Description

Technical Field

[0001] This utility model relates to the field of tape slitting machine technology, and in particular to a tape slitting machine cutter gap adjustment mechanism. Background Technology

[0002] A roll-type long strip adhesive tape slitting machine is a device that cuts long rolls of adhesive tape into multiple narrow rolls. After the tape is placed on a fixed roller, the position of the roller is adjusted so that it drives the tape roll to contact the cutting blades, which then cut the tape to a set width. The equipment allows for adjustment of the blade gap and slitting speed, adapting to tapes of different thicknesses and materials. It is widely used in packaging, electronics, and other fields, efficiently achieving fixed-width slitting of long strips of adhesive tape to meet diverse production needs.

[0003] In related technologies, the adjustment of existing tool gaps is quite cumbersome, and is mostly done manually. Workers manually adjust the tools one by one. When adjusting the tool position, workers need to use measuring tapes or other aids to prevent inconsistent spacing. The adjustment is not only cumbersome and slow, but also prone to errors, which is not conducive to the precise cutting of tape.

[0004] Therefore, we propose a tape slitting machine cutter gap adjustment mechanism to solve the above problems. Utility Model Content

The output shaft of the movable servo motor 5 is fixedly connected to the threaded rod 6, and the movable servo motor 5 can drive the threaded rod 6 to rotate.

[0039] In this embodiment, a fixed roller 9 is fixedly installed on one side of the movable base 8, which can be used to fit the rubber tube onto the fixed roller 9 for easy cutting.

[0040] In this embodiment, a fixed wheel 13 is fixedly sleeved on the outer side of the cutting roller 12. Four guide rods 14 are fixedly installed on one side of the fixed wheel 13. Multiple limiting grooves are opened on one side of the fixed wheel 13 to facilitate the restriction of the movement trajectory of the threaded ring 19 and multiple cutter wheels 20.

[0041] In this embodiment, an external threaded post 15 is rotatably sleeved on the outer side of the cutting roller 12. A limiting wheel 16 is fixedly installed on the left end of the external threaded post 15. A plurality of limiting protrusions are provided on one side of the limiting wheel 16.

[0042] In this embodiment, the adjustment mechanism includes a threaded ring 19 and multiple springs 21. Multiple cutter wheels 20 are slidably sleeved on four guide rods 14. Multiple springs 21 are sleeved on each of the four guide rods 14. The two ends of the multiple springs 21 respectively abut against the corresponding cutter wheels 20. The left ends of the four springs 21 located on the left side abut against the fixed wheel 13. The same threaded ring 19 is slidably sleeved on the four guide rods 14.

[0043] In this embodiment, a linkage disc 17 is fixedly installed on the right end of the external threaded column 15. The right ends of the four guide rods 14 are slidably connected to the left side of the same linkage disc 17. The left side of the fixing knob 11 is in contact with the right side of the linkage disc 17, so that the linkage disc 17 can be squeezed by the fixing knob 11, thereby driving the limiting wheel 16 and the fixing wheel 13 to make close contact and perform limiting.

[0044] In this embodiment, a rotating wheel 18 is fixedly installed on the right side of the linkage disk 17, which can drive the linkage disk 17 to rotate.

[0045] Working principle: When cutting the tape, the operator places the tape sleeve onto the fixed roller 9, then starts the equipment. The moving servo motor 5 starts, driving the threaded rod 6 to rotate. A threaded sleeve 7 is threaded onto the threaded rod 6, and a movable base 8 is fixedly fitted onto the outer side of the threaded sleeve 7. A movable opening is opened on one side of the movable bracket 2, and the movable base 8 is slidably installed inside the movable opening. Therefore, the threaded sleeve 7 cannot rotate with the threaded rod 6. The rotation of the threaded rod 6 drives the threaded sleeve 7 to move axially, and the movement of the threaded sleeve 7 drives the movement of the movable base 8, which in turn drives... The fixed roller 9 moves along with the glue tube. After the glue tube moves to contact the cutter wheel 20, the cutting servo motor 4 is started. The cutting servo motor 4 drives the cutting roller 12 to rotate, which in turn drives multiple cutter wheels 20 to rotate, cutting the glue tube into rolls of film with uniform width. When the required width of the roll changes, the operator stops the equipment and manually rotates the fixing knob 11. The fixing knob 11 is threadedly connected to the threaded hole on one side of the cutting bracket 10. Therefore, when the fixing knob 11 rotates, it moves axially. After the fixing knob 11 moves, it interacts with the linkage plate 1. There is a gap between wheel 7 and wheel 18. After the operator holds wheel 18, he pulls wheel 18 and linkage plate 17 towards the cutting bracket 10. The movement of linkage plate 17 drives the external threaded column 15 and limit wheel 16 to move. Limit wheel 16 moves away from fixed wheel 13. At this time, there is no movement interference between the two. The operator can drive linkage plate 17 and external threaded column 15 to rotate through wheel 18. Threaded ring 19 is threaded on external threaded column 15. Four guide rods 14 are fixedly installed on one side of fixed wheel 13. Threaded ring 19 is slidably sleeved on the four guide rods 14. On the guide rod 14, the external threaded column 15 rotates, causing the threaded ring 19 to move axially. The movement of the threaded ring 19 compresses the first cutter wheel 20 on the right side. The cutter wheel 20 moves to the left under compression. Four springs 21 are fixedly installed on the left side of each of the multiple cutter wheels 20. Therefore, when the first cutter wheel 20 is compressed and moves, the four springs 21 on its left side compress the second cutter wheel 20, causing it to move. Repeating the above steps, the multiple cutter wheels 20 move to the left synchronously, thereby adjusting the gap between the cutter wheels 20 and completing the control of the spacing.

[0046] The technological advancements of this invention compared to existing technologies are as follows: It can move the fixed roller 9, causing it to bring the rubber tube on it into contact with multiple cutting wheels 20. The cutting wheels 20 then cut the rubber tube into rolls of uniform width, increasing the practicality of the equipment and the stability during cutting. Furthermore, the rotation of the external threaded column 15 drives the threaded ring 19 to move, which in turn compresses the rightmost cutting wheel 20. The first cutting wheel 20 is compressed by four springs 21 on one side, which in turn compresses the second cutting wheel 20. The multiple cutting wheels 20 move sequentially, thereby adjusting the spacing between them, increasing the applicability and convenience of the equipment.

Specific embodiments have been used to illustrate the principles and implementation methods of this application. These embodiments are merely illustrative and are intended to aid in understanding the method and core concepts of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims.
