Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of foam processing, in particular to a foam semi-cutting device. Background Art
[0002] Before use, the foam tape roll is in a continuous state. When in use, single pieces need to be torn off for use. Therefore, the foam tape needs to be semi-cut. The top of the foam tape is attached with a self-adhesive release paper, and the bottom of the foam tape is attached with a bottom release paper. The foam tape advances under the traction of a traction mechanism. According to process requirements, the bottom release paper and the foam tape need to be cut at a certain distance to facilitate single-piece use after tearing during operation, while keeping the complete self-adhesive release paper intact to ensure a continuous state before use, that is, semi-cut processing of the foam tape. Since both the top and bottom surfaces of the foam tape are sticky, after the foam tape is semi-cut, the foam tape will stick to the long strip cutter and move with the long strip cutter, causing the foam tape to shift, resulting in deviation in the subsequent semi-cutting of the foam tape.
[0003] Therefore, a foam semi-cutting device that solves the above problems is needed. Summary of the Utility Model
[0004] The utility model provides a foam semi-cutting device. Through the setting of the foam tape support plate, it not only supports the foam tape but also blocks the foam tape that sticks to the long strip cutter after semi-cutting, solving the problem that the deviation of the foam tape caused by the foam tape sticking to the cutter affects the semi-cutting accuracy of the foam tape.
[0005] The technical solution of the utility model is realized as follows:
[0006] The foam half-cutting device comprises a frame, on which a cutter mounting plate is slidably mounted along the Z-axis direction, the cutter mounting plate is horizontally arranged, the cutter mounting plate is transmission-connected with a linear drive mechanism, a long strip cutter for half-cutting the foam material strip is fixedly mounted on the top of the cutter mounting plate, the long strip cutter extends along the Y-axis direction, a foam material strip support plate for supporting the foam material strip is arranged above the cutter mounting plate, an avoidance long strip hole for avoiding the long strip cutter is arranged on the foam material strip support plate, and a limiter for limiting the top of the foam material strip is arranged above the foam material strip support plate. The top plate has two limit screws threadedly mounted on the limit top plate for limiting the long strip cutter to the half-cutting position, each of the limit screws has a locking nut threadedly mounted on it, the lower end of each limit screw passes through the foam material strip support plate, when the long strip cutter moves up to the half-cutting position, the lower ends of the two limit screws rest against the top of the cutter mounting plate, the foam material strip passes between the limit top plate and the foam material strip support plate and is transported along the X-axis direction, the foam material strip support plate and the limit top plate are both fixedly mounted on the frame and are both arranged parallel to the cutter mounting plate.
[0007] As a preferred technical solution, both ends of the foam material strip support plate are bent downward to form fixed plates, each of the fixed plates is fixedly installed on the frame, and each of the fixed plates is vertically provided with a long waist hole for adjusting the corresponding installation position of the fixed plate.
[0008] As a preferred technical solution, a guide roller is rotatably mounted on both sides of the frame through an adjustable bracket.
[0009] As a preferred technical solution, each of the adjustable brackets includes two fixed columns fixedly mounted on the frame, each of the fixed columns is hinged with an adjustment arm via an adjustment bolt, and the two end shafts of each guide roller are respectively fixedly mounted on the corresponding adjustment arm.
[0010] As a preferred technical solution, two slide rails are arranged on the frame along the Z-axis direction, a slider is slidably installed on each of the slide rails, both ends of the cutter mounting plate are respectively fixedly installed on the corresponding sliders, and the linear drive mechanism includes a cylinder fixedly installed on the frame, and the piston rod of the cylinder is fixedly connected to the cutter mounting plate.
[0011] By adopting the above technical solution, the beneficial effects of the utility model are as follows:
[0012] 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 up 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.
[0013] 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, and thus make this device suitable for half-cutting foam tapes of different thicknesses.
[0014] Since two limit screws are threadedly installed on the limit top plate, the limit screws can limit the formation of the cutter mounting plate and stop the cutter from moving to the half-cut position. Brief Description of the Drawings

The foam tape passes through between the limit top plate 6 and the foam tape support plate 4 and is conveyed along the X-axis direction. Both the foam tape support plate 4 and the limit top plate 6 are fixedly mounted on the frame 1 and are both arranged parallel to the cutter mounting plate 2.

[0025] Both of the two locking nuts 8 are arranged above the limit top plate 6. After the position adjustment of the limit screw rod 7 is completed, the locking nuts 8 are rotated to lock the limit screw rod 7.
[0026] In summary, through the setting of the foam tape support plate, the present utility model not only supports the foam tape, but also blocks the foam tape adhered to the long cutter after half-cutting, solving the problem that the deviation of the foam tape caused by the adhesion of the foam tape to the cutter affects the half-cutting precision of the foam.
