Abstract

A button winding and crimping equipment, including a power device, a transmission device, a winding device, a thread turning device, a jumper pressing device and a control switch; it is used for winding and pressing the sewing thread around the button of the clothes to make the button The sewing thread between the clothing and the clothes is bundled to protect the sewing thread from abrasion and prevent the sewing thread from breaking, so that the sewn buttons are upright and durable. Each turn of the button sewing thread is compressed to prevent slack in the wrapped thread. Since the power of the winding device, turning device and jumper pressing device comes from the same drive device, the start and phase of each action are precisely controlled through mechanical transmission, which ensures the reliable winding and pressing process; the cam shaft Bearing contact is used between them, which not only reduces power consumption, but also improves the life of the machine; because the winding and crimping process is a precise mechanical transmission process, the reliability, accuracy and efficiency of its operation are far superior to those of weak or micro-current Controlled devices of the same type.

Description

A button winding crimping equipment

technical field

The invention relates to a device for wrapping and pressing sewing threads around clothes buttons, in particular to a device for winding and pressing sewing threads between clothes and buttons.

Background technique

In order to keep the surface of the clothes flat, especially the top of the button, it is necessary to reserve a gap between the back of the button and the fabric to be nailed when the button is nailed, so as to ensure the smoothness of the top of the button. Flat; but this sewing method creates a set of scattered seams between the button and the garment. If any one of the sewing threads in this group of scattered sewing threads breaks for some reason, it will cause the button to loosen or even come off. Simultaneously, this group of scattered sewing thread also can cause button to sag under the effect of button gravity, affects the attractive in appearance of clothing. These problems are particularly prominent in thicker fabric suits and coats.

In the prior art, in order to solve the above, it has gone through several stages of development: first, the garment processing adopts the method of manual operation to wind the ordinary thread on the sewing thread of the button, and then the winding thread is pressed tightly to avoid the slack and thread ends of the winding thread. Falling off; this method can well solve the above-mentioned problems in garment processing under the condition of pressing the thread once in a circle, but as the labor cost rises, this method gradually becomes unacceptable. In modern large-scale production, people have developed many solutions to the above problems: one of them is to develop elastic threads made of artificial rubber plastic substances, which rely on their own adhesion to tighten and fix sewing threads after winding, However, due to the high price of this thread, few varieties, and problems such as loss of viscosity after washing, it is seldom used; as an improvement of this method, as disclosed in Chinese patent 00216938. The winding method of heat-melting solidification, the temperature is often too low or too high during use, and it often burns woolen and chemical fiber clothing, and the winding is also easy to become brittle, and it will fall off after several washes. These problems basically limit the application of this technology. Another type of winding and knotting equipment disclosed in Chinese patent 200480019257.6 is a kind of equipment that can realize winding and knotting, but the equipment is respectively provided with a first driving device for driving the winding arm and a user The technology of setting two or more driving devices in one device increases the difficulty of control for the coordinated action between the driving devices, and the error and delay of signal transmission are both May cause confusion in system operation.

Contents of the invention

Therefore, the present invention is formed based on the consideration of the above-mentioned problems. The object of the present invention is to provide a device for winding the thread around the sewing thread of the button of the clothes and compressing the winding thread and the sewing thread at the same time, wherein The winding thread is firmly and automatically wound on the sewing thread between the back of the button and the surface of the clothing, and the winding thread at the back is pressed against the previously wound thread, and at the same time, a group of sewing threads connecting the button and the surface of the clothing are bound Comes in a bunch to avoid fraying and breaking of sewing thread, keep buttons and sewing thread upright.

Therefore, the present invention provides a button winding crimping equipment, including a power device that provides a power source for the movement of each part of the device, a transmission device that transmits the power source according to the needs of different parts, and alternately puts the winding wire on the line.

The process ensures the tightness and straightness of the button sewing thread, and prevents the winding thread from falling off and failing; the winding device includes a hollow main winding shaft, a winding head that can slide relative to the axial direction of the main winding shaft but does not rotate relatively, and a transmission gear 1. The cam that pushes the winding head to move in the axial direction and its reset mechanism, wherein the ratio of the rotation frequency of the winding head to the rotation frequency of the cam that pushes the winding head to reciprocate in the axial direction is 2:1, which is the thread turning after winding the sewing thread , wire jumper, and wire crimping have prepared effective line segments; the thread turning device includes a pair of non-closed arc-shaped slots that are relatively installed and can rotate relative to each other, transmission gears, cams that promote the rotation of non-closed arc-shaped slots, sliding shafts and their Reset mechanism, above the non-closed arc-shaped slot, there is a neutral area with a central arc angle exceeding 5 degrees but less than 180 degrees. It is carried out above the area; the jumper pressing device contains a jumper, a cam, a sliding shaft and a reset mechanism thereof.

Its working principle is: when the sewing button is placed on the button bracket, the button bracket supports the button sewing thread to the center of the arc-shaped slot on the same plane; after that, the power device starts and drives the winding thread first The winding head of the device rotates, and puts the winding wire in the arc-shaped slot of the turn-over device; when the winding wire finishes winding around the neutral area of the arc-shaped slot, the winding head on the winding device continues to rotate, and the winding head on the cam The winding thread is directly applied to the sewing thread of the button under the push of the button; when the winding head winds again to the neutral area of the non-closed arc-shaped slot on the thread turning device, the non-closed arc-shaped slot turns to the front of the button no more than 90 degrees, causing the winding wire to fall off from the non-closed arc-shaped slot; at this time, the jumper pressing device is activated under the action of the cam, and the winding wire that falls off from the slot is tightened, so that the wire that was originally placed in the arc-shaped slot The inner wrapping thread is tightly pressed on the wrapping thread that is applied on the button sewing thread to achieve the purpose of protecting and binding the button sewing thread, and also avoids the loosening of the wrapping thread; in the process of tightening the jumper thread, The arc-shaped wire groove is reset to the same plane by the reset mechanism, and the winding head also places the thread nozzle above the wire groove under the action of the reset mechanism to complete the first winding and crimping process; the winding head continues to rotate and repeat the above steps. Winding crimping process, until the specified number of winding turns is reached, the power unit stops working.

As a preference of the transmission device in the present invention, the working frequency of different devices and the phase positions of corresponding components are controlled by the number of teeth of the gears, so as to realize the coordinated actions of different components. As an alternative to the transmission, a sprocket drive or even a toothed drive can also achieve the object of the invention.
