[0012] The transverse slide 26 is slidably connected to the bottom of the transverse linear guide 9. The tail end of the transverse driving cylinder 11 is hinged at the left end of the transverse linear guide 9. The top end of the piston rod of the right end of the transverse driving cylinder 11 is connected to the transverse slide 26. The transverse driving cylinder 11 is used to drive the transverse slide 26 to translate left and right along the horizontal direction on the transverse linear guide 9. The lower end of the small swing arm 19 and the middle of the swing arm 12 are hinged at the middle and right ends of the transverse slide 26 respectively; a limiter 10 is fixed on the left end of the transverse slide 26 to limit the position of the small swing arm 19 swinging to the left in the plane shown in the figure. A sliding cross sleeve 27 is hinged at the upper part of the swing arm 12; a threaded cross sleeve 28 is hinged at the middle part of the small swing arm 19; the guide rod 13 is composed of a coaxial threaded portion and a smooth rod portion, the threaded portion at the left end of the guide rod 13 is screwed through the threaded hole of the threaded cross sleeve 28, and the smooth rod portion at the right end of the guide rod 13 slides through the through hole of the sliding cross sleeve 27, and a spiral compression spring 21 is sleeved on the outside of the smooth rod portion of the guide rod 13, one end of the compression spring 21 is against the nut on the left side of the guide rod 13, and the other end is against the left end face of the sliding cross sleeve 27, and the compression spring 21 transmits pressure to the swing arm 12 through the sliding cross sleeve 27; an A tension spring 20 is connected between the left end of the guide rod 13 and the limit member 10. The corner of the V-shaped cutter swing arm 14 is hinged to the lower part of the swing arm 12, and a B tension spring 22 is connected between the left half of the cutter swing arm 14 and the upper part of the swing arm 12 corresponding to the cutter swing arm 14; the top of the cutter 15 is hinged at the left end of the cutter swing arm 14, and the two ends of the connecting rod 16 are hinged to the lower part of the cutter 15 and the swing arm 12 near the lower end. An L-shaped plate 29 is fixed at the lower end of the swing arm 12 (the two can also be an integrated structure), and the top roller 17 and the corner roller 25 are respectively installed at the left and right ends of the bottom of the L-shaped plate 29. A roller is installed at the top of the swing arm 12, and a protrusion is provided on the left side of the upper part of the swing arm 12, and a mounting hole 32 for mounting a tape roller is provided on the protrusion. A fixed limit plate 7 and a cutter limit plate 18 are respectively installed at the upper and lower ends of the right side of the frame 1.

[0013] like Figure 1, the seat bearing 23 is fixed on the frame 1, and the lifting rocker arm 4 is fixedly connected to the inner ring of the seat bearing 23. Driven by the lifting drive cylinder 5, it can swing up and down around the rotation center of the seat bearing 23 in the direction shown in the figure. The tail of the lifting drive cylinder 5 is hinged on the frame 1, and the end is hinged on the lifting rocker arm 4. The longitudinal linear guide 6 and the transverse linear guide 9 are fixed on the frame 1. The movable limit plate 8 is hinged on the longitudinal linear guide 6, and can swing up and down around the hinge point in the direction shown in the figure. As shown in the figure, the movable limit plate 8 is located at the lower limit position. The tail of the transverse drive cylinder 11 is hinged on the transverse linear guide 9, and the end is hinged to the transverse slide 26. The transverse drive cylinder 11 can drive the transverse slide 26 to translate left and right on the transverse linear guide 9 along the horizontal direction shown in the figure. The limiter 10 is fixed on the transverse slide 26 to limit the position of the small swing arm 19 to swing to the left in the plane shown in the figure; the swing arm 12 and the small swing arm 19 are hinged on the transverse slide 26 and can swing around the hinge point in the plane shown in the figure; the sliding cross sleeve 27 is hinged on the swing arm 12, and the threaded cross sleeve 28 is hinged on the small swing arm 19, and both can swing around the hinge point in the plane shown in the figure. The threaded part of the guide rod 13 passes through the threaded hole of the threaded cross sleeve 28, and the smooth rod part passes through the smooth hole of the sliding cross sleeve 27. The compression spring 21 is sleeved on the smooth rod part of the guide rod 13, one end of which presses on the nut on the left side of the guide rod 13, and the other end presses on the left end face of the sliding cross sleeve 27, and the pressure is transmitted to the swing arm 12 through the sliding cross sleeve 27. When the swing arm 12 swings to the left, the compression spring 21 is compressed to provide the swing arm 12 with a rightward restoring force. The cutter 15 is hinged on the cutter swing arm 14, and the cutter swing arm 14 is hinged on the swing arm 12. One end of the B tension spring 22 is hung on the swing arm 12, and the other end is hung on the cutter swing arm 14. When the cutter swing arm 14 rotates counterclockwise, the B tension spring 22 is stretched, providing a clockwise restoring force to the cutter swing arm 14. The left end of the connecting rod 16 is hinged on the cutter 15, and the right end is hinged on the cutter swing arm 14. When the cutter swing arm 14 rotates counterclockwise, the connecting rod 16 constrains the cutter 15 to move along the desired path and cut the tape. The top rollers 17 and 25 are responsible for compacting the tape 2 on both sides of the material 3 to ensure that the tape does not lift up.

[0014] Working process of the present invention: When working, first install the adhesive tape (roller) 2 on the protruding part of the upper part of the swing arm 12. Figure 1 This is the initial state of the system. At this time, the lifting drive cylinder 5 is extended, the lifting rocker arm 4 is at the upper limit position, and the horizontal linear guide rail 9 and all parts installed on the horizontal linear guide rail 9 are lifted to the upper limit of the position shown in the figure through the pull rod 24. The material 3 is in place, and the tape 2 is in the ready state shown in the figure.

[0015] like Figure 2As shown, during the retraction of the lifting drive cylinder 5, the lifting rocker arm 4 is pulled to the lower limit position shown in the figure. At this time, the transverse linear guide rail 9 and all parts installed thereon (hereinafter referred to as the system) move downward with the lifting rocker arm 4. During the downward movement of the system, the small swing arm 19 is separated from the limit range of the movable limit plate 8. Under the pull of the A tension spring 20, the small swing arm 19 swings counterclockwise around the hinge point, driving the threaded cross sleeve 28 to rotate counterclockwise around the hinge point of the small swing arm 19, pulling the guide rod 13 and driving the swing arm 12 to swing counterclockwise around the hinge point, driving the tape 2 to stick to the left side of the material 3 shown in the figure, and the corner roller 25 is also attached to the left side of the material 3. The lifting drive cylinder 5 continues to retract to the fully retracted position of the cylinder. At this time, because the system is driven downward by the lifting drive cylinder 5, the corner roller 25 moves downward along the left side of the material 3, and the tape 2 is completely compacted on the left surface of the material 3.

[0016] like Figure 3 As shown, the lifting drive cylinder 5 extends out, pushing the lifting rocker arm 4 to the upper limit position shown in the figure, and lifting all system parts to the upper limit position shown in the figure through the pull rod 24. At this time, because the tape 2 has been attached to the left surface of the material 3, the tape 2 is pulled out during the upward process of the system. When the system runs to the position shown in the figure, the tape 2 is pulled out and is in the state shown in the figure, and the tape on the left side of the material 3 is completed.

[0017] like Figure 4 , the lifting drive cylinder 5 remains in the extended state, and the transverse drive cylinder 11 is extended, pushing the transverse slide 26 to translate to the right along the transverse linear guide 9 in the plane shown in the figure. At this time, the entire system is driven to translate to the right, pulling the tape 2. When the transverse drive cylinder 11 is fully extended into place, the tape 2 is pulled to the state shown in the figure, completing the preparation for pasting the upper surface of the material 3.

[0018] Figure 5 As shown, the lateral drive cylinder 11 remains in the extended state, and the lifting drive cylinder 5 retracts, driving the system downward. During this process, the tape 2 is attached to the upper surface of the material 3, completing the adhesion to the upper surface of the material 3. During the downward movement of the system, the compression spring 21 always applies pressure, so that the swing arm 12 is always pressed on the surface curve of the fixed limit plate 7. Under the constraint of the fixed limit plate 7, the top roller 17 presses the tape 2 on the right surface of the material 3. During the downward movement of the system, the cutter swing arm 14 contacts the cutter limit plate 18, and the surface curve of the cutter limit plate 18 forces the cutter swing arm 14 to swing counterclockwise, driving the cutter 15 to complete the cutting action of the tape 2. When the lifting drive cylinder 5 is fully retracted, all actions are completed.

[0019] After all the actions are completed, the lifting drive cylinder 5 extends to lift the whole system. After the lifting drive cylinder 5 is in place, the horizontal drive cylinder 11 retracts to drive the whole system back to the Figure 1 The initial state shown is ready to apply tape to the next package of material.
