[0002] Papermaking is a significant invention of the working people of ancient China. It can be made in two forms: mechanical and handmade. Mechanical papermaking involves continuous production on a papermaking machine. Pulp suitable for paper quality is diluted with water to a certain concentration, initially dehydrated on the machine's wire section to form wet paper sheets.

[0032] like Figures 1 to 12As shown, a papermaking raw material crushing device includes a hollow cylinder 1, the upper surface of the hollow cylinder 1 is fixedly connected to a feed hopper 2, the bottom of the hollow cylinder 1 is fixedly connected to a discharge hopper 3, the bottom of the discharge hopper 3 is fixedly connected to a support leg 4, the front and rear sides of the hollow cylinder 1 are fitted with U-shaped plates 5, the front and rear sides of the U-shaped plate 5 are each provided with a first circular hole 6, the front and rear sides of the hollow cylinder 1 are each provided with a strip hole 7, the inner wall of the strip hole 7 is fitted with a cylinder 8, the surface of the cylinder 8 is aligned with the inner wall of the first circular hole 6 Fixed connection, a second circular hole 9 is opened on the front and back sides of the U-shaped plate 5, the inner wall of the second circular hole 9 and the back of the U-shaped plate 5 are fixedly connected with a crushing mechanism 10, the surface of the crushing mechanism 10 is in contact with the inner wall of the strip hole 7, the front of the hollow cylinder 1 is fixedly connected with a lifting mechanism 11, the surface of the lifting mechanism 11 is fixedly connected with a third bearing 12, the surface of the cylinder 8 is fixedly connected with a fourth bearing 13, and the surfaces of the third bearing 12 and the fourth bearing 13 are fixedly connected with a connecting plate 14.

[0033] Among them, the crushing mechanism 10 includes a first motor seat 101, a first drive motor 102, a crushing roller 103 and a first bearing 104. The front of the first motor seat 101 is fixedly connected to the back of the U-shaped plate 5, the upper surface of the first motor seat 101 is fixedly connected to the bottom of the first drive motor 102, the output end of the first drive motor 102 is fixedly connected to one end of the crushing roller 103 through a coupling, the surface of the crushing roller 103 is fixedly connected to the inner ring of the first bearing 104, the inner wall of the second circular hole 9 is fixedly connected to the outer ring of the first bearing 104, and the surface of the crushing roller 103 is in contact with the inner wall of the strip hole 7.

[0034] The lifting mechanism 11 includes a second motor base 111, a second drive motor 112, a threaded column 113, a threaded cylinder 114, a hollow block 115, a U-shaped column 116, a second bearing 117 and a fixed block 118.

[0035] It should be noted that, through the cooperation of the U-shaped plate 5, the cylinder 8 and the strip hole 7, the crushing mechanism 10 can only move to the left or right. When the second drive motor 112 on the lifting mechanism 11 drives the threaded column 113 to rotate, the hollow block 115 can be moved upward or downward through the cooperation of the threaded column 113 and the threaded barrel 114, and the distance between the left and right crushing mechanisms 10 is changed through the cooperation of the U-shaped plate 5, the first circular hole 6, the strip hole 7, the cylinder 8, the third bearing 12, the fourth bearing 13, the connecting plate 14 and the U-shaped column 116. At this time, by changing the distance between the left and right crushing mechanisms 10, the size of the crushed raw material can be changed.

[0036] like Figures 1 to 5 As shown, a scale 15 is fixedly connected to the front of the hollow cylinder 1, and the bottom of the scale 15 is in contact with the upper surface of the U-shaped plate 5. A pointer 16 is fixedly connected to the front of the U-shaped plate 5, and the back of the pointer 16 is in contact with the front of the scale 15.

[0037] It should be noted that, through the cooperation of the scale 15 and the pointer 16 , the user can intuitively judge the distance between the left and right pulverizing mechanisms 10 .

[0038] like Figures 1 to 13 As shown, a locking groove 17 is provided at the bottom of the U-shaped plate 5, and a strip ring 18 is fixedly connected to the left and right sides of the hollow cylinder 1. The inner wall of the strip ring 18 and the inner wall of the locking groove 17 are both fitted with locking columns 19. The bottom of the locking column 19 and the left and right sides of the hollow cylinder 1 are fixedly connected with an electric telescopic rod 20, and the front and rear sides of the U-shaped plate 5 are fixedly connected with reinforcement blocks 21.

[0039] It should be noted that the side of the electric telescopic rod 20 is fixed to the hollow cylinder 1, and the telescopic end of the electric telescopic rod 20 is fixed to the bottom of the locking column 19. The locking column 19 can only move up and down through the bar ring 18, and the locking column 19 can be controlled to move up or down through the electric telescopic rod 20. At the same time, a plurality of locking grooves 17 are provided at the bottom of the U-shaped plate 5, and when the U-shaped plate 5 is moved to a suitable position, the locking column 19 is inserted into the locking groove 17, so that the U-shaped plate 5 can be locked, and the force applied to the lifting mechanism 11 when the crushing mechanism 10 crushes the raw materials is reduced, thereby effectively improving the service life of the lifting mechanism 11. The reinforcement block 21 is located at the locking groove 17, and the opening at the bottom of the locking groove 17 can be locked by the reinforcement block 21, so that the locking groove 17 is not easily deformed.

[0040] The working principle of the utility model is as follows: first, the distance between the left and right crushing mechanisms 10 is adjusted according to the crushing requirements. When adjusting, the locking column 19 is separated from the locking groove 17 by the electric telescopic rod 20. Then, the threaded column 113 is driven to rotate by the second driving motor 112, and the hollow block 115 is moved upward or downward by the cooperation of the threaded column 113 and the threaded cylinder 114. At the same time, the left and right crushing mechanisms 10 are adjusted by the cooperation of the U-shaped plate 5, the first circular hole 6, the strip hole 7, the cylinder 8, the third bearing 12, the fourth bearing 13, the connecting plate 14 and the U-shaped column 116. The distance between the two crushing mechanisms 10 changes. When the two crushing mechanisms 10 move to the appropriate position, the second drive motor 112 stops driving the threaded column 113 to rotate, and the two crushing mechanisms 10 are stopped at the appropriate position through the self-locking property of the thread between the threaded column 113 and the threaded barrel 114. At this time, by changing the distance between the left and right crushing mechanisms 10, the size of the crushed raw materials can be changed. Then, the locking column 19 is inserted into the locking groove 17 through the electric telescopic rod 20, and the U-shaped plate 5 is locked through the cooperation of the locking column 19 and the locking groove 17.

[0041] When crushing the raw materials, the first drive motors 102 on the two crushing mechanisms 10 are first turned on to make the two crushing rollers 103 rotate in opposite directions. Then, the raw materials enter the hollow cylinder 1 through the feed hopper 2 and are crushed by the two counter-rotating crushing rollers 103. The crushed raw materials are discharged through the discharge hopper 3.

[0042] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention.
