[0002] Adhesive tape is a viscoelastic polymer that possesses both liquid and solid properties. It has a wide range of applications, not only in everyday office applications but also in numerous other industries, including automotive, electronics, papermaking and printing, construction, home appliances, new energy, and rail transit. Therefore, tape trimming equipment is an essential tool in the tape production process, crucial for improving production efficiency and ensuring product quality.

[0003] An existing patent (publication number: CN217458203U) proposes a trimming device for tape production and processing. This device utilizes a cutting mechanism that starts with a motor that rotates a screw, which in turn moves an adjustment block, which in turn moves a movable plate, which in turn moves a T-shaped slider within a C-shaped slide rail. When the movable plate reaches the desired height, the motor stops, and a pneumatic cylinder starts to move a curved plate, which in turn moves a triangular blade. The triangular blade trims the rotating, reeled tape, offering the advantages of convenient and neat cutting. However, the device's blade position remains fixed, making it inflexible for manufacturers' tape trimming needs of varying sizes and requirements, thus limiting its practicality.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0021] See Figure 1-5 A trimming device for tape production and processing includes a fixed frame bottom plate 1, a blade 6, and a first side plate 2 and a second side plate 3 integrally formed with the fixed frame bottom plate. The front ends of the first side plate 2 and the second side plate 3 are provided with a notch for placing a first winding roller 4. The film master tape sleeve is placed on the first winding roller 4. An adjustment plate 15 is fixedly provided on the outer wall between the first side plate 2 and the second side plate 3, which are close to each other. A control cavity is opened inside the adjustment plate 15, and an adjustment structure is provided inside the control cavity. A control motor 13 is provided on the outer wall of the second side plate 3. 3 is provided with a circular hole on the upper part, in which a worm 12 is provided, and a control motor 13 is fixedly connected to the worm 12. A rotating shaft 10 is provided in the control cavity, and cylindrical protrusions provided at the bottom and top of the control cavity are fixed in the grooves at both ends of the rotating shaft 10 to realize the rotation of the rotating shaft 10 in the control cavity. A worm gear 11 is fixedly connected to the middle of the rotating shaft 10, and the worm gear 11 and the worm 12 are meshed with each other. A gear 9 is fixedly connected to the bottom of the rotating shaft 10, and racks 8 are provided on the front and rear sides of the gear 9, and the racks 8 and the gear 9 are meshed with each other.

[0022] In addition, a thread is provided on the worm 12 , and the worm 12 passes through the left and right sides of the second side plate 3 and is fixed by nuts.

[0023] refer to Figure 3 、 Figure 4The left end of the rack 8 is fixedly connected to the connecting rod 7, and the lower end of the connecting rod 7 is fixedly connected to the collar 16. The collar 16 is detachably connected to the blade 6 by a screw (not indicated in the figure). Slides 14 are opened on the left and right sides of the bottom of the adjusting plate 15. The width of the connecting rod 7 corresponds to that of the slide 14. The connecting rod 7 can slide along the slide 14. At the same time, a protrusion is provided at the bottom of the rack 8, which can slide along the strip slides provided on both sides of the bottom of the adjusting plate 15 to ensure the stability of the rack during movement.

[0024] refer to Figure 1 、 Figure 3 、 Figure 5 A storage box 17 is provided in the middle of the right connecting rod 7. A cavity is opened inside the storage box 17, and a tape measure 18 is provided inside the cavity. A notch is provided on the left side of the forward side of the storage box 17. The zero scale end of the tape measure 18 is placed outside the notch and is fixed with a Velcro A19. A Velcro B20 is fixedly connected to the left connecting rod 7 at the same height, and the Velcro A19 and the Velcro B20 are adhesively connected.

[0025] In addition, when the measuring tape 18 is not in use, it can be placed in the storage box 17. When the measuring tape 18 is in use, the Velcro A19 and Velcro B20 of the zero scale of the measuring tape 18 are bonded together, and the measuring tape 18 extends and retracts with the movement of the connecting rod 7. The scale can clearly display the distance between the blades 6.

[0026] refer to Figure 1 When a smaller tape master is replaced on the first roller 4, the master tape is wound on the second roller 21 arranged between the first side plate 2 and the second side plate 3, and the trimmed tape is wound on the third roller 22 under the fixed shaft 5 for collection. At this time, the control motor 13 is turned on, and the worm 12 drives the worm wheel 11 to rotate counterclockwise. At the same time, the gear 9 also rotates counterclockwise. The rack 8 engaged with the gear 9 drives the connecting rod 7 to approach each other, and the distance between the blades 6 on both sides is reduced. The tape measure 18 shrinks accordingly, and the control motor 13 is turned off according to the scale displayed on the tape measure to complete the size adjustment. It should be noted that, in order to facilitate control, we can install a control switch on the side of the second side plate 3. The control switch can be equipped with a single-chip microcomputer of the control system, which can adjust the opening and closing, direction, speed, etc. of the control motor 13.

[0027] As a preferred embodiment of the above implementation scheme, a slide groove can be opened above the fixed shaft 5, a rotatable ball is set in the slide groove, a protrusion is set on the inner wall of the ring 16, the protrusion slides along the slide groove, the rolling of the ball reduces friction, and the adjustment is faster.

[0028] Working principle: when the tape needs to be trimmed, first put the tape sleeve on the first roll 4, tear the edge of the tape and place it on the third roll 22, and finally fix it on the outer wall of the third roll 22. After fixing, turn on the control motor 13 to control the worm 12 to rotate. The worm 12 drives the worm wheel 11 to move clockwise and counterclockwise, and the gear 9 fixed on the same rotating shaft 10 also moves clockwise and counterclockwise at the same time. The racks 8 on both sides engaged with the gear 9 move away from each other and approach each other, and the blade 6 connected to the rack 8 through the connecting rod 7 changes in distance. Comparing the size of the film, the tape measure on the connecting rods 7 on both sides is extended and extended to display the scale to help the production workers make adjustments. After the adjustment is completed, turn off the control motor 13, and the blade 6 will start trimming the tape fixed between the second roll 21 and the third roll 22 according to the set size. The cut tape is wound on the middle of the third roll 22. After the trimming is completed, the third roll 22 can be removed to collect the tape.

[0029] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention.
