DETAILED DESCRIPTION

[0020] The following is a further non-limiting detailed description of the technical solution of the utility model in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-2 The utility model provides a technical solution: a fiber crushing device, including a bracket 1, a box body 2 is fixedly connected to the upper side of the bracket 1, a cavity 3 is opened in the box body 2, a feed port 4 is opened on the upper side of the box body 2, and a discharge port 5 is opened on the lower side of the box body 2. The feed port 4 and the discharge port 5 are both connected to the cavity 3, and the lower inner wall of the cavity 3 is inclined toward the discharge port 5.

[0022] A partition plate 6 is vertically arranged on one side of the feed inlet 4 close to the center of the cavity 3 and extending into the cavity.

[0023] A plurality of first crushing components 7 and a plurality of second crushing components 8 are respectively arranged on both sides of the partition plate 6 , and the plurality of first crushing components 7 and the plurality of second crushing components 8 are arranged vertically downward.

[0024] The first crushing assembly 7 and the second crushing assembly 8 have the same structure, and both include two groups of horizontally arranged rotating rollers 9. A plurality of crushing knives 10 are axially arranged on the two groups of rotating rollers 9. The crushing knives 10 are existing crusher blades. The crushing knives 10 on the two groups of rotating rollers 9 are arranged in sequence at intervals, so that the crushing knives 10 on the two groups of rotating rollers 9 intersect with each other to form a cross shearing area 13, so as to shear and crush the fibers.

[0025] One side of the roller shafts of the two groups of rotating rollers 9 passes through the box body 2 and is fixedly connected to a driving motor 11 . The driving motor 11 is fixedly connected to the outer wall of the box body 2 to drive the rotating rollers 9 to rotate.

[0026] A plurality of guide plates 12 are provided on the side of the two groups of rotating rollers 9 facing away from the cross-shearing area 13. The guide plates 12 are located between two adjacent groups of shredder knives 10 on the same rotating roller 9 and are in direct contact with the side surfaces of the shredder knives 10. The guide plates 12 are trapezoidal and have grooves 14 formed between the two groups of rotating rollers 9, which facilitate the concentration of fiber shredders in the cross-shearing area 13.

[0027] A conveying assembly 15 is provided on the side of the second crushing assembly 8 away from the first crushing assembly 7. The conveying assembly 15 includes a shell 16. The shell 16 and the inner wall of the cavity 1 3 form a cavity 2 17. The cavity 2 17 is in the shape of a straight slot. The cavity 2 17 is provided with a transfer outlet 18 and a transfer inlet 19 on one side of the crushing cavity. The transfer outlet 18 is located on the upper side of the transfer inlet 19.

[0028] Among them, the guide plates 12 on both sides of the rotating roller 9 of the first crushing component 7 are fixedly connected to the inner wall of the cavity 3 and one side of the partition 6 respectively, and the guide plates 12 on both sides of the rotating roller 9 of the second crushing component 8 are fixedly connected to the shell 16 and one side of the partition 6 respectively.

[0029] A conveyor belt 20 is rotatably connected in the cavity 17 . The conveyor belt 20 is an existing conventional conveyor belt. A plurality of baffles 21 are evenly connected to the belt surface of the conveyor belt 20 . The baffles 21 are in direct contact with the inner wall of the cavity 17 on the side away from the belt surface of the conveyor belt 20 .

[0030] The baffle 21 is arranged to be inclined upward from left to right, with a specific inclination angle of 15°. The lower end of the transmission outlet 18 is inclined toward the side of the cavity 3 and is connected with a connecting plate 22. The inclination of the connecting plate 22 is consistent with the deflection angle of the baffle 21, both of which are 15°. When the baffle 21 is transmitted to the transmission outlet 18, it docks with the connecting plate 22 to form an inclined surface that facilitates the fiber fragments to fall into the cavity 3.

[0031] The connecting plate 1 22 extends away from the side of the conveying component 15 to the top of the cross-shearing area 13 of the second shredder component 8, so that the fiber shredders falling from the baffle 21 fall on the top of the cross-shearing area 13 of the second shredder component 8, which is convenient for secondary shearing and crushing of the fiber shredders.

[0032] A screen 23 is disposed laterally at the lower side of the cavity 1 3, and the screen 23 is located below the first crushing component 7 and the second crushing component 8, and is used to screen out the crushed materials after shearing and crushing of the first crushing component 7 and the second crushing component 8;

[0033] One side of the screen 23 is inclined toward the lower side of the inlet 19 of the conveying component 15 and is connected to it. An oscillator 24 is provided on the lower side of the screen 23 away from the conveying component 15. After being screened out by the vibration of the oscillator 24, the crushed materials that have not passed through the screen 23 after shearing and crushing are transferred to the conveying component 15, and the conveying component 15 transports the crushed materials to the top of the second crushing component 8, and they are sheared and crushed for the second time by the second crushing component 8.

[0034] In this embodiment, the broken fiber material is fed into the feed port 4 , and after being sheared and broken for multiple times by the multiple groups of first crushing components 7 , the fiber material forms fiber crushed materials that fall on the screen 23 .

[0035] The fiber fragments smaller than the mesh size of the screen 23 are shaken off by the vibration of the oscillator 24 and are drawn out from the discharge port 5 along the lower inner wall of the cavity.

[0036] The fiber fragments that have not passed through the screen 23 gradually move to the inlet 19 under the vibration of the oscillator 24, and fall into the second cavity 17 through the inlet 19. Under the operation of the conveyor belt 20, the baffle 21 pushes the fiber fragments that have fallen into the second cavity 17 to the outlet 18, and fall from the outlet 18 under the action of gravity, and fall through the connecting plate 1 22 into the cross-shear area 13 of the second fragment assembly 8 for secondary shearing and crushing, and then pass through the vibration screening of the screen 23 for the second time, and then fall out from the discharge port 5.

[0038] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit them. Although the utility model is described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features can be replaced by equivalents, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
