Detailed Implementation

[0019] Reference Figs. 1 to 3 The embodiments of this utility model will be further described below.

[0020] A trimming device for processing PET high-frequency hot melt adhesive tape includes a base plate 1 and two trimming mechanisms 100 respectively installed on both sides of the base plate 1 for trimming the tape. Each trimming mechanism 100 includes a support plate 2 for supporting the movement of the tape, a motor 3 mounted on the support plate 2, a turntable 4 mounted on the output end of the motor 3, and a grinding disc 5 mounted on the turntable 4. The support plate 2 has a receiving channel 21 that mates with the grinding disc 5, and the grinding disc 5 moves within the receiving channel 21. The base plate 1 is fixed with the two trimming mechanisms 100. Two fixed platforms 6 are respectively corresponding to 0. The fixed platform 6 is movably connected to the corresponding support plate 2. The support plate 2 is movable on the base plate 1. An L-shaped fixed plate 7 is installed on the support plate 2. The output end of the motor 3 passes through the fixed plate 7 and is rotatably connected to the fixed plate 7. The fixed plate 7 is provided with a limiting part 200 that cooperates with the support plate 2 to limit the material belt. The limiting part 200 includes a connecting rod 8 connected to the fixed plate 7, a mounting frame 9 connected to the connecting rod 8, and a positioning roller 10 rotatably connected to the mounting frame 9. The positioning roller 10 rolls on the material belt.

[0021] Working principle: The PET high-frequency hot melt adhesive tape (referred to as "tape") to be trimmed passes between the two trimming mechanisms 100 and moves continuously along the length of the base plate 1. The two sides of the tape are placed on the corresponding support plates 2. The motor 3 drives the turntable 4 and the grinding disc 5 on it to rotate at high speed. The contact friction between the edge of the grinding disc 5 and the outer edge of the tape achieves the trimming of the tape. The setting of the channel 21 on the support plate 2 facilitates the normal high-speed rotation of the grinding disc 5 to trim the edge of the tape and avoids interference of the support plate 2 with the rotation of the grinding disc 5.

[0022] During the trimming process, the positioning roller 10 on the limiting part 200 rolls on the material strip and cooperates with the support plate 2 to clamp and limit the material strip on the support plate 2 without affecting the movement of the material strip. This ensures that the material strip remains in the predetermined position during the movement, preventing the material strip from shifting during the trimming process and thus ensuring the accuracy of the trimming. Ultimately, this achieves the goal of limiting the material strip that moves and is transmitted on the support plate 2 during trimming by cooperating with the limiting part 200 and the support plate 2 to limit the material strip and prevent the material strip from shifting its movement posture during the trimming process, thus affecting the accuracy of the trimming.

[0023] The fixed plate 7 has a first threaded hole 11 that is threaded to one end of the connecting rod 8. The other end of the connecting rod 8 is equipped with a first bearing 12. The other end of the connecting rod 8 is rotatably connected to the mounting frame 9 through the first bearing 12. The mounting frame 9 is equipped with a stop rod 13 that is connected to the fixed plate 7. A second bearing 14 is passed through both ends of the positioning roller 10. The positioning roller 10 is rotatably connected to the mounting frame 9 through the two second bearings 14, so as to realize the rotatable connection of the positioning roller 10 on the mounting frame 9, which facilitates the rolling of the positioning roller 10 on the material belt.

[0024] The vertical height of the positioning roller 10 can be adjusted by rotating the connecting rod 8, thereby ensuring that the positioning roller 10 can roll on strips of different thicknesses and limit the strips on the support plate 2. This achieves the limitation of strips of different thicknesses, improves the adaptability of the trimming equipment, and the stop rod 13 prevents the mounting frame 9 from rotating when the connecting rod 8 rotates, thus affecting the limitation of the positioning roller 10 on the strip. At the same time, it prevents the mounting frame 9 from shaking when the positioning roller 10 rotates on the mounting frame 9, thereby enhancing the structural stability of the entire limiting part 200.

[0025] A support rod 15 is connected to the support plate 2. The support rod 15 slides on the base plate 1. The base plate 1 has a guide groove 22 that is slidably connected to the support rod 15. The bottom of the support rod 15 is arc-shaped, and an adjusting screw 16 is rotatably connected to the support rod 15. The adjusting screw 16 is rotatably connected to the support rod 15 through a bearing. The fixed platform 6 has a guide channel 17 that is movably connected to the support plate 2 and a second threaded hole 18 that is threadedly connected to the adjusting screw 16. A movable groove 19 is opened on the inner wall of the bottom of the guide channel 17. A ball bearing 20 is movably connected in the movable groove 19. The support plate 2 abuts against the ball bearing 20.

[0026] The adjusting screw 16 is connected to the fixed platform 6 through the second threaded hole 18. The adjusting screw 16 is rotatably connected to the support rod 15, which facilitates the rotation of the adjusting screw 16 to push the support rod 15 to slide in the guide groove 22. At this time, the support plate 2 moves in the guide channel 17, which facilitates the adjustment of the position of the support plate 2. This allows the support plates 2 of the two trimming mechanisms 100 to move closer or further apart to accommodate material strips of different widths. At the same time, the threaded connection between the adjusting screw 16 and the second threaded hole 18 on the fixed platform 6 ensures that the support plate 2 remains stable after adjustment, avoiding inaccurate trimming caused by the instability of the support plate 2.

[0027] The support rod 15 slides in the guide groove 22 on the base plate 1. The bottom of the support rod 15 is arc-shaped to reduce the friction between the support plate 2 and the guide groove 22, so that the support plate 2 can remain stable during movement. The ball bearing 20 reduces the friction between the support plate 2 and the guide channel 17 on the fixed platform 6, making the movement of the support plate 2 smoother and improving the stability of the support plate 2 during movement.

[0028] A guide sleeve 23 that mates with the output end of the motor 3 is provided on the fixed plate 7. The output end of the motor 3 passes through the guide sleeve 23 and is rotatably connected to the guide sleeve 23, so as to realize the rotatable connection between the output end of the motor 3 and the fixed plate 7, so that the motor 3 can smoothly drive the grinding disc 5 to rotate and trim the material strip when it is working.
