Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a belt bonding device suitable for use when manufacturing an endless belt by bonding both ends of a strip-shaped belt.

Conventionally, belts have been bonded by applying an adhesive to the bonded portion of the belt, heating it, and keeping it under pressure for a predetermined period of time using a vise or the like.

However, this process is time-consuming and the temperature of the adhesive drops during pressure bonding using a vise or the like, so strong adhesion cannot be expected.

The present invention is intended to solve these conventional disadvantages, and aims to provide a belt bonding device that is easy to handle and can also perform strong bonding.

Next, embodiments of the present invention will be described with reference to the drawings.

The belt adhesive device stands out from a lower M1 and an upper cover 3 which is pivotally supported to the lower M1 via a hinge 2.

The upper M3 and the lower M1 overlap and hold the belt to be bonded (details will be described later) in a crimped state.

An elongated engagement hole 4 is bored in the lower lid 1, and the upper lid 3
A tightening shaft 6 having a roller 5 at its tip that engages with the engagement hole 4 is rotatably attached to the shaft.

The end of the tightening shaft 6 passes through the upper lid 3 and projects to the outside, and a rotating handle 7 is attached thereto.

A coil spring 8 is provided between the handle 7 and the upper M3 (
(See FIG. 2) When the top cover 3 is opened, if the roller 5 always returns to a position where it does not collide with the elongated engagement hole 4, the roller 5 etc. will not be damaged during operation.

A surface plate 9 is attached to the lower lid 1 in a floating manner by a spring 10.

Numeral 11 is a screw for adjusting the strength of the spring 10, and is used to adjust the position (vertical position) of the surface plate 9 according to the thickness of the belt. Numeral 12 is a guide screw for the surface plate 9, which is used to adjust the position of the surface plate 9 in accordance with the thickness of the belt. It is slidably fitted.

Further, on both sides of the surface plate 9, there are clamps 13 made of thin steel plates.
13 is attached with one end thereof fixed to the hinge 2 side.

At the other ends of both clamp holders 13 and 13, presetters 14 and 14, which can be freely engaged and detached from the lower surface of the surface plate 9, are attached (see Fig. 3). 20 is held on the surface plate 9.

A heating plate 16 containing an electric heater 15 is provided in the center of the upper lid 3.

Note that a similar heater may be provided on the surface plate 9.

Furthermore, an inclined plate 17 that engages with the roller 5 is provided on the lower surface of the engagement hole 4 (on the back side in FIG. 1), so that when the roller 5 rotates due to rotation of the handle 7, the roller 5 By lightly moving the inclined plate 17 along its inclined surface, the upper cover 3 is tightened even more strongly when attached to the lower cover 1.

Next, the operation of this device will be explained.

First, electricity is applied to the electric heater 15 to preheat it for several minutes.

Next, apply adhesive to the bonding points of the belts 20, 20 to be bonded, polymerize the bonding points, and glue both sides +-2.
(Fix L20 on the surface plate 9 with clamps i3.13 (state shown in Fig. 1).

Next, the upper lid 3 is placed on the lower M1, that is, the upper lid 3 is closed, and the handle 7 is rotated.

By rotating the handle 7, the first lid 3 is firmly pressed against the lower lid 1.

At this time, the surface plate 9 is slightly displaced downward while compressing the spring 10, and the repulsive force of the spring 10 due to this displacement acts as a pressing force on the belts 20 and 20.

(-Thus, by adjusting the spring pressure of the spring 10 with the screw 11, the pressing force on the bell 1-20.20 can be adjusted by 3.

After keeping the adhesive, belt, etc. in a heated and pressurized state for a predetermined period of time, return the handle 7 to release the upper cover and open it. By removing 13, 13, a belt with completed adhesion can be obtained.

As described above, according to the present invention, the belt is coated with adhesive at the bonding point, is polymerized, is fixed on the surface plate using a clamping tool, and the top cover is closed and this state is maintained for a predetermined period of time. Since the belt can be glued, it is extremely easy to handle and does not require skill, so it can be operated even with uncontrolled tools.

Moreover, since bonding can be done under constant heating and pressure,
The present invention is highly practical as it has the extremely practical effect of making it possible to mass-produce endless belts with stable quality without product fluctuation. can.
