Disclosure of Invention
In order to overcome the defects, the invention provides the computer special paillette machine which has high processing efficiency and stable and reliable processing and can be suitable for paillettes with different shapes and sizes.
In order to achieve the purpose, the technical scheme adopted by the invention is that the computer special paillette machine comprises a frame, a workbench, a machine head and a control unit, wherein the control unit controls the workbench to move forwards, backwards, leftwards and rightwards along a horizontal plane through a motor, the machine head is fixed on the frame and is driven to work through the control unit, the machine head comprises a cam, a stamping device, a feeding device, a receiving device and a horizontal guide rail, the cam is fixed on the horizontal guide rail, the control unit controls the cam to transversely move and rotate along the horizontal guide rail through the motor, the cam is connected with a stamping connecting rod and a receiving connecting rod, the stamping connecting rod drives the stamping device to reciprocate, the receiving connecting rod drives the receiving device to reciprocate, the stamping device comprises a plurality of stamping pins and punches with the same quantity, the end faces of the stamping pins are of structures with different sizes and shapes, a feeding port and a discharging port are arranged in the vertical direction of the punches, the stamping pins are matched with the corresponding stamping pins, the stamping pins are provided with a stamping pin spring to provide upward spring restoring force, the stamping pins comprises a lighting strip plate and a strip-shaped spring, the lighting plate and the strip-shaped spring are matched with the other ends of the strip-shaped spring to the corresponding to the other ends of the strip-shaped spring and the strip-shaped spring, the strip-shaped stamping pin is matched with the other ends to the strip-shaped stamping pin and the other ends are matched with the strip-shaped stamping spring and the strip-shaped stamping spring, and the strip-shaped stamping spring is matched with the strip-shaped and the strip-shaped stamping spring and the pressing spring to the pressing punch, and the positions are in one-to-one correspondence.
The beneficial effects provided by the invention are as follows: under the drive of a motor, a cam of a machine head drives a stamping device through a stamping connecting rod, a stamping needle can be downwards inserted into a punched hole of a punch, a part of a strip-shaped paillette entering along a feed port of the punch at the punched hole position is downwards punched and extruded to be adhered to a corresponding position of a piece clothing with colloid on a workbench, then the piece clothing is controlled by a control unit to move to a needed next process position along a horizontal surface, back and forth, left and right on the workbench, the stamping processing of a piece of paillette can be completed, the processing mode can realize the processing of paillettes with various sizes and different shapes, only the end surface shape of the stamping needle is required to be changed into the required size and shape, the stamping needles with a plurality of end surfaces with different sizes and shapes are arranged for convenience in use, and the punch, the press head, the driving press roller and the driven press roller are correspondingly arranged at the same time, the required punching needle is directly selected, after one paillette processing is completed, the same cam drives the pressing head to move downwards through the material collecting connecting rod, so that the pressing head drives the driving pressing roller to rotate through the ratchet wheel, the driving pressing roller and the driven pressing roller rotate backwards together in the process, the pressed strip paillette strips punched by the punching needle are pulled backwards by one station from the discharge hole, the strip paillette strips are integrally fed into one station, preparation is made for the next punching process, during the material collecting process, the punching needle returns upwards under the action of the punching needle spring, during the punching process, the pressing head returns upwards under the action of the restoring spring, the driving pressing roller slides due to the action of the ratchet wheel and does not drive the strip paillette strips to move reversely, so that the reciprocating processing efficiency is high, compared with the two processes of punching and material collecting are respectively controlled through two motors, the intermittent motion of the stamping and receiving processes is realized through the same cam, zero error can be achieved, errors can not be accumulated slowly due to the accuracy of the motor, the situation that the receiving process is performed simultaneously when the stamping process is performed can be effectively avoided, and finally, the process is disordered is caused.
Further, the pressure head is connected with adjusting screw, adjusting screw adjusts the initial position of pressure head and receipts material connecting rod looks butt, because the cam drives the decurrent maximum stroke of receipts material connecting rod and is fixed, the initial position of pressure head and receipts material connecting rod looks butt through adjusting screw's adjustment, thereby adjust the stroke that the pressure head was driven by receipts material connecting rod, and then adjust the stroke that initiative compression roller and driven compression roller drove banded spangle strip carry, through this kind of regulation, when punching needle terminal surface size is little (the required processing spangle size is little promptly), the carry stroke of receipts material also needs to be adjusted little, just can more effective utilization banded spangle strip, not cause the waste.
Furthermore, the workstation includes fixed frame and rubber material's middle elastic cloth all around, compares the hard mesa that is in fixed horizontal plane, through rubber material's middle elastic cloth, can make the punching press go up the paillette better bonding on the piece clothing, and can not cause the punching press not put in place or the punching press to cross the first phenomenon such as cause the thimble.
Further, be equipped with the connector on the punching press connecting rod, be equipped with the recess on the connector, be equipped with the lug on the punching needle, the lug cooperatees with the recess, through the recess on the connector with punch the lug on the needle cooperate, can be when selecting different punching needles, only need along horizontal guide rail remove cam and punching press connecting rod can, such structure makes the selection and the change of punching needle all simple and fast.
Further, be equipped with coaxial pivoted outer cam and interior cam on the cam, outer cam drives punching press connecting rod reciprocating motion, interior cam drives receipts material connecting rod reciprocating motion, sets up outer cam and interior cam to when making outer cam promote the punching press connecting rod, interior cam and receipts material connecting rod are in the unmatched state, otherwise when interior cam promotes receipts material connecting rod, outer cam and punching press connecting rod are in the unmatched state, and such structure is simpler reasonable.
Further, the rear end of the discharge hole is provided with a guide pipe, the guide pipe is connected with the discharge hole and is pressed with the driving press roller and the driven press roller, the strip-shaped paillette strips are led to the position pressed by the driving press roller and the driven press roller from the discharge hole through the guide pipe, the stability of material collection can be improved, and the strip-shaped paillette strips can be prevented from being wound in a mess during material collection.
The invention is described in further detail below with reference to the drawings and examples.
