Description

Technical Field

[0001] The present invention relates to a special computer sequin machine. Background Art

[0002] Most of the existing sequin machines fix sequins with fixed shapes and colors on the sequin clothes by thermal adhesion, or sew the sequins on the sequin clothes after punching holes in the middle of the sequins. The processing of these two forms of sequins is relatively complex, the processing efficiency is low, and there are restrictions on the shape and size of the sequins, and sequins with too small sizes cannot be processed. Summary of the Invention

[0003] In order to overcome the above-mentioned deficiencies, the present invention provides a special computer sequin machine with high processing efficiency, stable and reliable processing, and applicable to sequins of various different shapes and sizes.

[0004] To achieve the above object, the technical solution adopted by the present invention is: a special computer sequin machine, including a frame, a workbench, a machine head and a control unit. The control unit controls the workbench to move horizontally forward, backward, left and right through a motor. The machine head is fixed on the frame and is driven to work by the control unit. The machine head includes a cam, a punching device, a feeding device, a collecting device and a horizontal guide rail. The cam is fixed on the horizontal guide rail. The control unit controls the cam to move horizontally and rotate along the horizontal guide rail through a motor. The cam is connected with a punching connecting rod and a collecting connecting rod. The punching connecting rod drives the punching device to reciprocate. The collecting connecting rod drives the collecting device to reciprocate. The punching device includes a plurality of punch needles and punch heads with the same quantity. The end faces of the plurality of punch needles are structures with various different sizes and shapes. The punch head is provided with a punching hole in the vertical direction and a feeding port and a discharging port in the horizontal direction. The punch needles are correspondingly matched with the punching holes. A punch needle spring is arranged on the punch needles. The punch needle spring provides an upward spring restoring force for the punch needles. The feeding device includes a sequin tape reel and a strip-shaped sequin strip. The strip-shaped sequin strip is wound around the sequin tape reel and extends into the feeding port of the punch head. The collecting device includes a plurality of pressure heads, a driving pressure roller and a driven pressure roller with the same quantity. The pressure heads are matched with the driving pressure roller through ratchets. One end of the pressure heads is matched with the collecting connecting rod. A return spring is arranged at the other end of the pressure heads. The return spring provides an upward spring restoring force for the pressure heads. The discharging port is correspondingly located at the position where the driving pressure roller and the driven pressure roller are pressed tightly. The number of punch needles and pressure heads is the same and they are arranged in parallel with the horizontal guide rail and their positions correspond one by one.

[0005] The beneficial effects provided by the present invention are as follows: Driven by a motor, the cam of the machine head first drives a stamping device through a stamping connecting rod, which can insert a punching needle downward into the punching hole of a punch head. The part of the strip-shaped sequin strip that enters through the feeding port of the punch head and is at the punching position is punched downward and squeezed and adhered to the corresponding position of the adhesive-coated piece of clothing on the workbench. Then, the piece of clothing on the workbench is controlled by a control unit to move horizontally back and forth and left and right to the next required process position, and thus the stamping process of one sequin can be completed. This processing method can achieve the processing of sequins of various different sizes and shapes. Only the end face shape of the punching needle needs to be changed into the required size and shape. For the convenience of use, multiple punching needles with different end face sizes and shapes are provided, and at the same time, the punch head, the pressure head, the driving pressure roller, and the driven pressure roller are correspondingly set. Just directly select the required punching needle. After completing the stamping process of one sequin, the same cam drives the pressure head to move downward through a material receiving connecting rod. As a result, the pressure head drives the driving pressure roller to rotate through a ratchet. During this process, the driving pressure roller and the driven pressure roller rotate backward together, pulling the pressed strip-shaped sequin strip that has been punched by the punching needle backward by one station from the discharging port, so that the whole strip-shaped sequin strip advances one station, preparing for the next stamping process. During the material receiving process, the punching needle returns upward under the action of a punching needle spring, and during the stamping process, the pressure head also returns upward under the action of a return spring. During this process, due to the action of the ratchet, the driving pressure roller slips and does not drive the strip-shaped sequin strip to move backward. In this way, the reciprocating processing efficiency is high. Compared with controlling the stamping and material receiving processes respectively by two motors, this intermittent movement of the stamping and material receiving processes realized by the same cam can achieve zero mistakes and will not cause errors to accumulate slowly due to the precision of the motor, effectively avoiding the situation that the material receiving process is also in progress while the stamping process is being carried out, and finally causing the process to be disordered.

[0006] Further, the pressure head is connected with an adjusting screw, and the adjusting screw adjusts the initial position where the pressure head abuts against the material receiving connecting rod. Since the maximum downward stroke of the cam driving the material receiving connecting rod is fixed, by adjusting the initial position where the pressure head abuts against the material receiving connecting rod through the adjusting screw, the stroke of the pressure head driven by the material receiving connecting rod is adjusted, and further the stroke of the driving pressure roller and the driven pressure roller driving the strip-shaped sequin strip to advance is adjusted. Through this adjustment, when the end face size of the punching needle is small (i.e., the size of the sequin to be processed is small), the advancing stroke of the material receiving also needs to be adjusted smaller to make more effective use of the strip-shaped sequin strip without causing waste.

[0007] Further, the workbench includes a surrounding fixed frame and an intermediate elastic cloth made of rubber material. Compared with a hard tabletop at a fixed horizontal plane, through the intermediate elastic cloth made of rubber material, the sequins stamped on the piece of clothing can be better adhered to the piece of clothing, and phenomena such as incomplete stamping or over-stamping resulting in thimble will not occur.

[0008] Further, a connector is provided on the stamping connecting rod, a recess is provided on the connector, a protrusion is provided on the punching pin, and the protrusion cooperates with the recess. By matching the recess on the connector with the protrusion on the punching pin, when selecting different punching pins, it is only necessary to move the cam and the stamping connecting rod along the horizontal guide rail. Such a structure makes the selection and replacement of the punching pins simpler and faster.

[0009] Further, an outer cam and an inner cam that rotate coaxially are provided on the cam. The outer cam drives the stamping connecting rod to reciprocate, and the inner cam drives the material receiving connecting rod to reciprocate. The outer cam and the inner cam are provided, and when the outer cam pushes the stamping connecting rod, the inner cam and the material receiving connecting rod are in an uncooperated state, and vice versa, when the inner cam pushes the material receiving connecting rod, the outer cam and the stamping connecting rod are in an uncooperated state. Such a structure is simpler and more reasonable.

[0010] Further, a guide pipe is provided at the rear end of the discharge port. The guide pipe connects the discharge port to the position where the active pressure roller and the driven pressure roller are pressed together. By guiding the strip-shaped sequin strip from the discharge port to the position where the active pressure roller and the driven pressure roller are pressed together through the guide pipe, the stability of material collection can be improved, and the strip-shaped sequin strip can be prevented from being randomly wound during material collection.
