[0028] The embodiment of the present utility model discloses a PE partition slitting device.

[0029] Embodiment 1

[0030] The present utility model provides a PE partition slitting device as shown in Figures 1-4 which includes a slitting frame 1. The slitting frame 1 is arranged in a U shape, and two symmetrically arranged rotating rods 2 are rotatably provided on one side inside. A conveying roller 3 is fixedly sleeved on the rod wall of the rotating rod 2. A conveying motor 4 is fixedly provided on the front side of the slitting frame 1. The end of the output shaft of the conveying motor 4 penetrates into the slitting frame 1 and is fixedly connected to the rotating rod 2. Transmission gears 21 are fixedly sleeved on the rear ends of the two rotating rods 2, and the two transmission gears 21 are cooperatively arranged;

[0031] Two symmetrically arranged support plates 5 are fixedly provided on the inner wall of the slitting frame 1. Through holes are formed in the interiors of the two support plates 5, a cutting knife 6 is arranged inside the through holes, a guiding block 7 is fixedly penetrated inside the cutting knife 6, a sliding hole for the guiding block 7 to slide is formed on the back side of the slitting frame 1, a fixing rod 8 is fixedly provided on the inner wall of the slitting frame 1, and a plurality of spaced slitting knives 9 are slidably sleeved on the rod wall of the fixing rod 8. A through hole for sliding with the fixing rod 8 is formed in the slitting knife 9, and a locking bolt 20 is threadedly penetrated through the top of the slitting knife 9, and the end of the locking bolt 20 is arranged in cooperation with the rod wall of the fixing rod 8.

[0032] Before slitting the PE separator, adjust the longitudinal movement speed of the cutting knife 6, adjust the position of the slitting knife 9 according to the specifications to be slit, and fix the position of the slitting knife 9 by the extrusion of the locking bolt 20 and the fixing rod 8. Then start the conveying motor 4, so that the two rotating rods 3 rotate relatively under the cooperation of the two transmission gears 21, so that the PE separator can enter between the two support plates 5 through the two conveying rollers 3. At this time, the adjacent two cutting knives 6 move intermittently and approach each other under the sliding cooperation of the guiding block 7 and the sliding hole, so that the separator can be slit by the cutting knife 6 during conveying and be in the shape of a plurality of strips with a fixed width. Subsequently, during the continuous movement of the separator, the side surface of the separator contacts the plurality of slitting knives 9, and the separator can be separated into multiple small separator blocks, thereby completing the slitting work of the PE separator.

[0033] Embodiment 2

[0034] On the basis of Embodiment 1, Embodiment 2 is to control the reciprocating movement speed of the cutting knife 6 to slit the separator into different specifications and sizes, as Figures 1-3 shown, a pushing and slitting mechanism is arranged between the two cutting knives 6 and the slitting frame 1. The pushing and slitting mechanism includes a push plate 10. A connecting plate 11 is fixedly provided on the outer side of the rear end of the guiding block 7. The connecting plate 11 is bent. A fixing plate 12 is fixedly provided on the back side of the slitting frame 1. A support spring 13 is fixedly provided on the side wall of the fixing plate 12 and is fixedly connected to the push plate 10 through the support spring 13. The push plate 10 is sleeved on the outer sides of the ends of the two connecting plates 11;

[0035] A push block 14 is fixedly provided on the outer wall of the push plate 10. A speed regulating motor 16 is fixedly provided on the outer wall of the slitting frame 1 through a motor fixing frame 15. A cam 17 is fixedly sleeved on the end of the output shaft of the speed regulating motor 16. The cam 17 is arranged in cooperation with the push block 14.

[0036] Before slitting, by controlling the rotational speed of the speed-regulating motor 16, the rotational speed of the cam 17 can be adjusted. At this time, the frequency of contact between the cam 17 and the push block 14 is controllable. When the cam 17 contacts the push block 14, the push block 14 can be pushed and, under the support of the support spring 13, cause the push plate 10 to move laterally. At this time, under the sliding fit between the guide block 7 and the sliding hole, the two connecting plates 11 are pushed and move closer to each other, enabling the two cutting knives 6 to approach and slit the partition. When the cam 17 separates from the push block 14, under the elastic recovery of the support spring 13, the push plate 10 and the connecting plate 11 rebound to their original positions, causing the cutting knives 6 to separate from the partition. Since the contact frequency between the cam 17 and the push block 14 is controllable, the cutting contact frequency between the cutting knives 6 and the partition can be adjusted, thereby completing the slitting of the partition in various width dimensions.

[0037] Embodiment 3

[0038] On the basis of Embodiment 2, in order to enable the connecting plate 11 to quickly move back after being pushed and drive the cutting knife 6 to return to its original position in Embodiment 3, as Figures 2-3 shown, two symmetrically arranged guide grooves are formed on the back side of the slitting frame 1. A guide rod 18 is fixedly inserted through the inside of the connecting plate 11, and the end of the guide rod 18 is slidably arranged in the guide groove, and a return spring 19 is fixedly arranged between the end of the guide rod 18 and the inner wall of the guide groove.

[0039] When the connecting plate 11 is pushed, through the sliding fit between the guide rod 18 and the guide groove, the connecting plate 11 moves stably. After a single slitting, the connecting plate 11 can drive the cutting knife 6 to move back to its original position through the synchronous cooperation of the return spring 19 and the support spring 13, ensuring that the slitting work can be carried out continuously and stably.

[0040] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
