Description

Technical Field

[0001] This utility model relates to the field of tape slitting technology, specifically to a tape slitting device with adjustable slitting distance. Background Technology

[0002] Adhesive tape is a strip-shaped product made by coating adhesives (such as pressure-sensitive adhesives, hot melt adhesives, etc.) onto a substrate such as film, paper, or cloth. Due to its characteristics of quick adhesion, easy peeling (in some types), and strong adaptability, it is widely used in various fields such as daily life, industry, and medicine. During the production process, adhesive tape needs to be cut to the required width.

[0003] Existing tape slitting machines do not allow for convenient adjustment of the slitting distance between the blades. Adjusting this distance often requires disassembling the blades and then reinstalling them according to the desired spacing, which is cumbersome. Therefore, a tape slitting device with adjustable slitting distance is proposed. Utility Model Content

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] This utility model provides a technical solution: such as Figures 1 to 4 As shown, in this embodiment, a tape slitting device with adjustable slitting distance includes a base 1. Two bearing seats 10 are fixedly installed on both sides of the upper end of the base 1. A rotating shaft 2 is rotatably installed between the two bearing seats 10. Another bearing seat 10 is fixedly installed on the upper end of each of the two bearing seats 10. Another rotating shaft 2 is rotatably installed between the other two bearing seats 10. A driving mechanism acting on the rotating shaft 2 is provided at the end of the rotating shaft 2. Fixed plates 12 are fixedly sleeved at both ends of the rotating shaft 2. A fixed cutting blade 3 and three movable cutting blades 4 are arranged between the two fixed plates 12. The fixed cutting blade 3 is fixedly sleeved on the outer wall of the rotating shaft 2, and the three movable cutting blades 4 are slidably sleeved on the outer wall of the rotating shaft 2. An adjustment mechanism acting on the three movable cutting blades 4 is provided between the two fixed plates 12. The adjustment mechanism is adjusted by... The device consists of a hinge 11, a rotating column 18, and an adjusting column 19. The two ends of the adjusting shaft 11 are fixedly connected to the rotating columns 18. The two rotating columns 18 are rotatably installed inside the two fixed plates 12. The fixed plates 12 have movable grooves that fit the rotating columns 18. One end of the rotating column 18, away from the adjusting shaft 11, extends to the outside of the fixed plate 12. The extended end of the rotating column 18 is fixedly connected to the adjusting column 19. The adjusting shaft 11 passes through one fixed cutting blade 3 and three movable cutting blades 4 in sequence. The adjusting shaft 11 is slidably connected to the fixed cutting blade 3. The outer wall of the adjusting shaft 11, away from the fixed cutting blade 3, has a first thread segment 15, a second thread segment 16, and a third thread segment 17 in sequence. The first thread segment 15, the second thread segment 16, and the third thread segment 17 are threadedly connected to the three movable cutting blades 4 respectively.

[0020] One of the fixed plates 12 has a locking bolt 20 threadedly connected to its top end, and the bottom of the locking bolt 20 abuts against the rotating column 18.

[0021] After the position of the three movable cutting blades 4 is adjusted by rotating the adjusting shaft 11, the adjusting shaft 11 can be locked by the locking bolt 20 to prevent the adjusting shaft 11 from rotating.

[0022] The pitch ratio of thread segment 15, thread segment 16, and thread segment 17 is 1:2:3.

[0023] With this configuration, when the adjusting shaft 11 is rotated, the ratio of the distances moved by the three movable cutting blades 4 is 1:2:3, thus ensuring that the spacing between two adjacent cutting blades is always the same.

[0024] Among them, a guide key 13 is fixedly connected to the outer wall of the rotating shaft 2. The guide key 13 is located on the side of the outer wall of the rotating shaft 2 away from the adjusting shaft 11. The inner walls of the three movable cutting blades 4 are all provided with keyways 14 that slide and fit with the guide key 13.

[0025] The guide key 13 and keyway 14 make the movement of the movable cutting blade 4 more stable.

[0026] The drive mechanism consists of a mounting frame 5 and a motor 7. The mounting frame 5 is fixedly installed on the upper end of the base 1. Two mounting slots 6 are opened on the mounting frame 5. The two mounting slots 6 are located in the extension direction of the two rotating shafts 2 respectively. The motors 7 are fixedly installed in the two mounting slots 6 respectively. The output shafts of the two motors 7 are fixedly connected to the ends of the two rotating shafts 2 respectively.

[0027] The motor 7 can control the rotation of two rotating shafts 2, thereby driving the fixed cutting blade 3 and the movable cutting blade 4 to rotate.

[0028] Two guide rollers 8 are suspended above the base 1. The two guide rollers 8 are distributed on both sides of the rotating shaft 2. The two ends of the guide rollers 8 are respectively rotatably connected to fixed vertical plates 9. The bottom of the fixed vertical plates 9 is fixedly connected to the base 1.

[0029] The conveyor belt can be guided by the guide roller 8.

[0030] This utility model provides a tape slitting device with adjustable slitting distance, and its specific working principle is as follows:

[0031] In use, loosen the locking bolt 20 to allow the adjusting shaft 11 to rotate freely. At this time, rotating the adjusting column 19 will drive the adjusting shaft 11 to rotate. Since the pitch ratio of the first thread segment 15, the second thread segment 16, and the third thread segment 17 is 1:2:3, the ratio of the distances the three movable cutting blades 4 move when rotating the adjusting shaft 11 is also 1:2:3, thus ensuring that the spacing between two adjacent cutting blades is always the same. According to the required width of the tape to be cut, adjust the spacing between the cutting blades to the required length. The adjusted spacing can be measured with a micrometer. Then tighten the locking bolt 20 to lock the adjusting shaft 11, ensuring that the adjusting shaft 11 will not rotate, thereby driving the movable cutting blades 4 to move, thus completing the adjustment of the cutting distance.

[0032] It should be noted that there will be a slight misalignment between the upper and lower cutting blades, similar to the two blades of scissors, which will not be described in detail here.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
