[0014] As a preferred technical solution, a coding component for coding and marking the foam composite sheet with uneven thickness is installed downstream of the traction coding knife seat, and the coding component includes a coding mounting frame installed on the traction coding knife seat, and a sliding frame is slidably mounted on the coding mounting frame along the Z-axis direction, and a pair of guide columns extending along the Y-axis direction are fixedly mounted on the sliding frame, and a number of movable plates are slidably mounted on the two guide columns, and a positioning knob is arranged between each of the movable plates and one of the guide columns, and an inkjet head is slidably mounted on each of the movable plates along the Z-axis direction, and a micrometer knob is arranged between the inkjet head and the movable plate.

[0015] As a preferred technical solution, each of the cache devices includes a fixed roller group fixedly installed on the frame, a sliding roller group is arranged below each of the fixed roller groups, and each of the sliding roller groups is slidably installed on the frame along the Z-axis direction. The fixed roller group includes a plurality of fixed rollers arranged in sequence along the X-axis direction, and each of the fixed rollers is arranged parallel to the Y-axis. The sliding roller group includes a lifting seat, and a plurality of sliding rollers arranged in sequence along the X-axis direction are rotatably installed on the lifting seat, and each of the sliding rollers is arranged parallel to the Y-axis. A sliding roller is arranged below the middle position of the two fixed rollers, and the foam material strips are staggered around the fixed rollers and the sliding rollers in sequence.

[0016] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0017] Since the fully automatic production equipment for foam sheet includes a half-cutting device, during the use of this equipment, the foam material tape is half-cut by the half-cutting device, and the self-adhesive release paper is retained. The foam material tape and the bottom release paper are cut at a certain distance, so that when in use, the foam or the release paper can be partially torn off. Then, the outer shape of the half-cut foam material tape is cut, and finally the foam sheet is obtained. At the same time, the equipment is also provided with a device for thickness detection and a device for spraying defective product codes, which is beneficial to distinguish and remove defective foam sheets.

[0018] Since the fully automatic production equipment for foam sheet includes a thickness detection tool holder, and a thickness detection platform is fixedly installed on the thickness detection tool holder. During the use of this equipment, the foam material tape continuously advances. First, the material tape is guided by the material tape edge de-wrinkling frame, which avoids the deviation of the foam material tape during thickness measurement and improves the accuracy of the thickness detection of the foam material tape. When the foam material tape passes through between the de-wrinkling roller and the material tape edge de-wrinkling elastic sheet, the material tape edge de-wrinkling elastic sheet flattens the wrinkles on both sides of the material tape, ensuring the flatness during the thickness detection of the foam material tape. When the foam material tape moves to the detection platform, negative pressure is formed at the position of the material tape flattening matrix holes, so that the bottom of the foam material tape adheres to the top of the suction detection platform, realizing the positioning of the foam material tape on the detection platform, thus avoiding the jitter of the foam material tape during thickness measurement and further improving the accuracy of the thickness detection of the foam material tape. At the same time, the laser displacement sensor emits a laser beam to the material tape and calculates the time difference of the laser beam reflected back by the material tape to calculate the thickness of the foam material tape, greatly reducing the error of the thickness detection of the foam material tape and accurately measuring the thickness of the foam material tape, so as to ensure that the subsequent defective foam material tape can be better detected.

[0019] Since the material tape flattening matrix holes include the middle material tape flattening matrix holes and the edge material tape flattening matrix holes, the foam material tape is sucked in different regions through the setting of the middle material tape flattening matrix holes and the edge material tape flattening matrix holes. Since the edges of the foam material tape are more likely to wrinkle than the middle position of the material tape, by increasing the number of the edge material tape flattening matrix holes, the suction force of the thickness detection platform on the edge of the foam material tape is increased, so that the more easily wrinkled edge is flattened on the thickness detection platform, further ensuring the accuracy of the thickness detection.

[0020] Since the wrinkle elastic sheet mounting rod is installed on the material tape edge de-wrinkling frame through two elastic clamping plates, during the use of this device, the elastic clamping plates themselves have elasticity and can automatically clamp the wrinkle elastic sheet mounting rod, thus realizing the quick adjustment of the wrinkle elastic sheet mounting rod. By rotating the wrinkle elastic sheet mounting rod, the force of the material tape edge de-wrinkling elastic sheet pressing on the material tape can be realized, so as to be applicable to the flattening of material tapes with different wrinkle conditions.

[0021] Since the foam half-cutting device includes a foam tape support plate, when using this device to half-cut the foam tape, the foam tape passes through between the limit top plate and the foam tape support plate, and advances along the X-axis direction under the traction of the traction mechanism. The foam tape support plate supports the foam tape. When the position to be half-cut moves to the position of the avoidance long hole, the traction mechanism stops pulling the foam tape. At this time, under the drive of the linear drive mechanism, the cutter mounting plate moves upward and abuts against the bottom of the limit screw. The long cutter passes through the avoidance long hole and moves to the half-cut position to cut off the foam tape and the bottom release paper, leaving the self-adhesive release paper. Then, under the drive of the linear drive mechanism, the long cutter resets. During the reset process of the long cutter, the foam tape support plate blocks the foam tape, preventing the foam tape from sticking to the long cutter after half-cutting and moving with the long cutter, thus avoiding deviation in subsequent foam half-cutting caused by the offset of the foam tape. After completing the half-cutting, the traction mechanism continues to pull the foam tape. When the next position to be half-cut moves to the position of the avoidance long hole, the traction mechanism stops pulling the foam tape and starts to half-cut the foam tape. This process is repeated until all positions to be half-cut are completed.

[0022] Since the foam half-cutting device includes a foam tape support plate, and the foam tape support plate is provided with oblong holes, the position where the foam tape fixing plate is fixedly installed on the frame can be adjusted through the oblong holes, so as to realize the distance between the foam tape support plate and the limit top plate, making this device suitable for half-cutting foam tapes of different thicknesses.

[0023] Since two limit screws are threadedly installed on the limit top plate, the limit screws can limit the formation of the cutter mounting plate to stop the cutter after it moves to the half-cut position. Brief Description of the Drawings
