For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] The following is combined with Figure 1-7 The present invention is further described.

[0022] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: a slitting device for transparent patch production.

[0023] The specific technical solution includes a base frame 1, a guide rod 3, a raw material roller 21, a winding shaft 12, a driving component, a slitting component, and a detection component.

[0024] A further design is as follows: a side panel 2 is fixedly provided on at least one side of the top of the base frame 1 . In this embodiment, the side panels 2 are fixedly connected on both sides of the top of the base frame 1 .

[0025] The guide rods 3 are rotatably connected to the outside of the side plate 2, and 3 to 5 groups of guide rods 3 can be provided to guide the raw materials.

[0026] Specifically, in order to facilitate replacement of the raw material roller 21, the raw material roller 21 is detachably arranged at one end of the side plate 2, and the raw material is wound around the raw material roller 21; Therefore, the outer sides of the two side panels 2 are fixedly connected with a second mounting frame 19, and a limiting cylinder 20 is penetrated and slidably connected in the second fixing frame. A second positioning threaded rod 22 is also threadedly penetrated and connected in the second mounting frame 19. The shafts on both sides of the raw material roller 21 can be inserted into the limiting cylinder 20, so the shafts on both sides of the raw material roller 21 are respectively inserted into the two limiting cylinders 20, and then the second positioning threaded rod 22 is rotated to contact the limiting cylinder 20 to fix the position of the limiting cylinder 20.

[0027] Specifically, the winding shaft 12 is detachably arranged at the other end of the side plate 2, and a plurality of winding rings 13 are detachably fixedly arranged outside the winding shaft 12; Therefore, the outside of the two side panels 2 is also fixedly connected with a first mounting frame 9; A sleeve 15 is rotatably connected to one of the first mounting frames 9, and a limiting sleeve 10 is passed through and slidably connected to the other first mounting frame 9. The limiting sleeve 10 is a three-quarter ring structure for engaging the winding shaft 12, and a first positioning threaded rod 11 is also threadedly connected to the first mounting frame 9. The first positioning threaded rod 11 penetrates the first mounting frame 9 and contacts the limiting sleeve 10. Therefore, one end of the winding shaft 12 is inserted into the sleeve 15, and the other end of the winding is engaged in the limiting sleeve 10. Then, the first positioning threaded rod 11 is rotated to fix the limiting sleeve 10 in contact, so that the winding shaft 12 can be quickly installed.

[0028] In order to drive the winding shaft 12 to rotate, a driving assembly is provided to drive the winding shaft 12 to rotate; The driving assembly includes a motor 18 fixedly connected to the outside of the first mounting frame 9, a first gear 14 fixedly connected to the outside of the sleeve 15, and a second gear 16 fixedly connected to the driving shaft of the motor 18. The first gear 14 is meshed with the second gear 16, so the second gear 16 is driven to rotate by the motor 18. The meshing of the second gear 16 with the first gear 14 can drive the winding shaft 12 to rotate. The end of the winding shaft 12 connected to the sleeve 15 is a rectangular structure, and the inner cavity of the sleeve 15 is also a rectangular structure. In this way, when the sleeve 15 rotates, the winding shaft 12 can be driven to rotate.

[0029] In order to cut the raw material into a plurality of strips, a cutting assembly is arranged outside the side plate 2 to cut the raw material into N strips, where N>1; Specifically, the slitting assembly includes a rotating rod 5 rotatably connected to the outside of the side plate 2, a plurality of cutting blades 6 fixedly connected to the outside of the rotating rod 5, and a driving machine 4 fixedly connected to the outside of the side plate 2, the driving shaft of the driving machine 4 is fixedly connected to the rotating rod 5, and the cutting blades 6 are used to cut the raw materials into several strips.

[0030] Among them, a fixing frame 7 is fixedly connected to the outside of the side plate 2, and an electric push rod 8 is fixedly connected to the fixing frame 7. The piston rod of the electric push rod 8 passes through the fixing frame 7 and is fixedly connected to a cutting knife 29, which is used to cut the raw materials.

[0031] In order to detect whether enough raw materials are wound on the winding ring 13, a detection component is arranged outside the side plate 2 to detect whether the raw materials outside the winding ring 13 are wound saturated.

[0032] The detection assembly includes a rotating arm 23 rotatably connected to the outside of the side plate 2, an adjusting rod 24 fixedly connected to the rotating arm 23, a mounting block 25 fixedly connected to the outside of the adjusting rod 24, and a proximity sensor 26 fixedly connected to the outside of the mounting block 25. A control module 27 is provided on the base frame 1, and an indicator light 28 is also fixedly connected to the base frame 1. The indicator light 28, the electric push rod 8, the drive machine 4, the proximity sensor 26 and the motor 18 are all electrically coupled to the control module 27, and the outside of the base frame 1 is hinged with a cylinder 17, and the piston rod of the cylinder 17 is connected to the rotating arm 23. The arm 23 is hinged, and the cylinder 17 pushes and adjusts the rotating arm 23, so it is convenient to control and adjust the distance between the proximity sensor 26 and the winding ring 13. When the raw material strip outside the winding ring 13 is wound to a certain thickness, it can be detected by the proximity sensor 26. After the proximity sensor 26 transmits the signal to the control module 27, the control module 27 turns off the motor 18 and starts the electric push rod 8 to drive the cutting knife 29 to move downward, cut off the raw material strip, and then take out the winding shaft 12. At the same time, the indicator light 28 lights up to remind the staff to come and deal with it.

[0033] The control module 27 may be a programmable controller, and the proximity sensor 26 is an existing product, and a corresponding model can be selected on the market, and the present invention does not limit the model.

[0034] In order for those skilled in the art to fully understand the technical solution, this application makes the following summary: First, place the raw material roll 21 wrapped with raw materials (PE film, release paper or film) between the two second fixing frames 7, then slide and adjust the limiting cylinder 20, so that the limiting cylinder 20 is inserted into the shaft rod on the side of the raw material roll 21, and then rotate the second positioning threaded rod 22 to contact the limiting cylinder 20 to fix the position of the limiting cylinder 20; Then, one end of the winding shaft 12 is inserted into the sleeve 15, and the other end of the winding is engaged in the limiting sleeve 10, and then the first positioning threaded rod 11 is rotated to abut and fix the limiting sleeve 10; Next, the raw material on the raw material roller 21 is pulled through the guide roller, corresponding to the winding shaft 12; Then, the driving machine 4 is started to rotate, and the driving machine 4 drives the rotating rod 5 to rotate, so that the cutting blade 6 on the rotating rod 5 slides over the raw material to cut it into several strips, and then the raw material is continuously pulled until the cut raw material strips correspond to the limiting ring, and then they are fixedly connected to the limiting ring; Finally, the motor 18 is started to drive the second gear 16 to rotate, and the second gear 16 drives the winding shaft 12 to rotate, and the winding ring 13 is driven to rotate by the rotation of the winding shaft 12, and then the raw material strip is wound by the winding ring 13; When the raw material strip outside the winding ring 13 is wound to a certain thickness, it can be detected by the proximity sensor 26. After the proximity sensor 26 transmits the signal to the control module 27, the control module 27 turns off the motor 18 and starts the electric push rod 8 to drive the cutting knife 29 to move downward, cuts the raw material strip, and then takes out the winding shaft 12.
