Description

Technical Field

[0001] The utility model belongs to the technical field of crushing processing, and particularly relates to a rubber crushing device. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under very small external forces, and can return to its original state after the external forces are removed.

[0003] China is a large rubber-consuming country. Since rubber products do not decompose naturally, improper treatment of waste rubber products will cause environmental pollution. Moreover, China's rubber resources are relatively scarce. Therefore, current rubber products are usually recycled. During recycling, rubber is usually broken. However, current crushing devices usually result in inconsistent particle sizes of the crushed rubber. The rubber particles of different sizes are mixed together and cannot be separated, making subsequent processing inconvenient. Summary of the Utility Model

[0004] The technical problem to be solved by the embodiments of the present application is to overcome the deficiencies of the prior art and provide a rubber crushing device for solving the problem of inconsistent sizes of crushed rubber.

[0005] The technical solution for the embodiments of the present application to solve the above technical problem is as follows: A rubber crushing device, which includes:

[0006] A housing, in which a crushing chamber is formed;

[0007] A crushing roller assembly, arranged in the crushing chamber inside the housing;

[0008] A screen, inclined and arranged at the bottom of the crushing roller assembly;

[0009] A conveying device, whose input port is correspondingly connected to the bottom end of the inclined screen, and the output port of the conveying device communicates above the crushing roller assembly.

[0010] Compared with the prior art, the above technical solution has the following beneficial effects:

[0011] The rubber products passing through are crushed by the crushing roller assembly. Then, the particles of different sizes formed are screened by the screen below. The particles of appropriate size fall below the screen for collection, and the large particles roll down along the inclined screen to the input port of the conveying device and are conveyed by the conveying device above the crushing roller assembly for re-crushing, so as to ensure that the large rubber particles can be re-crushed until they can pass through the screen, avoiding the problem of inconsistent sizes of rubber products after one-time crushing.

[0012] Further, the crushing roller assembly includes:

[0013] Two parallel rotation shafts are rotatably connected to the housing, and a driving mechanism is connected to the end of each rotation shaft.

[0014] A number of crushing teeth are arranged on the rotation shafts at intervals, and the crushing rolls on the two rotation shafts are arranged radially at intervals and staggered.

[0015] Furthermore, the crushing teeth on the two rotation shafts are arranged circumferentially at intervals and staggered.

[0016] Furthermore, arc-shaped inner walls that are clearance-matched with the outer contour of the crushing roll assembly are formed on both sides of the crushing cavity.

[0017] Furthermore, a number of crushing cones are arranged on the inner wall.

[0018] Furthermore, the conveying device includes: a conveying pipeline, the two ends of which are respectively communicated with the bottom end of the screen and above the crushing roll assembly;

[0019] A spiral body is arranged in the conveying pipeline;

[0020] A driving mechanism is used to drive the spiral body to rotate and feed.

[0021] Furthermore, the conveying pipeline includes: a vertical section, and the spiral body is accommodated in the vertical section;

[0037] As Figure 1 shown, a rubber crushing device provided by an embodiment of the present utility model includes: a housing, a crushing roller assembly, a screen, and a conveying device.

[0038] A crushing cavity is formed in the housing. The crushing roller assembly is arranged in the crushing cavity inside the housing. The screen is inclined and arranged at the bottom of the crushing roller assembly. The input port of the conveying device is correspondingly connected to the bottom end of the inclined screen, and the output port of the conveying device communicates above the crushing roller assembly.

[0039] The passing rubber products are broken by the crushing roller assembly. After that, the particles of different sizes formed are screened by the lower screen. The suitable particles fall below the screen for collection, and the large particles roll along the inclined screen to the input port of the conveying device and are conveyed by the conveying device to the upper part of the crushing roller assembly for re-crushing, so as to ensure that the large rubber particles can be re-crushed until they can pass through the screen, avoiding the problem of uneven sizes of rubber products after one-time crushing.

[0040] Among them, the crushing roller assembly includes: two parallel rotating shafts, and a number of crushing teeth are arranged at intervals on the two rotating shafts.

[0041] The two rotating shafts are rotatably connected to the housing, and a driving mechanism is connected to the end of the rotating shaft. A number of crushing teeth are arranged at intervals on the rotating shaft, and the crushing rollers on the two rotating shafts are radially spaced and staggered, that is, the crushing teeth on one side of the rotating shaft extend into the interval formed by the two crushing teeth on the other side of the rotating shaft, thus forming a radial staggered arrangement.

[0042] The crushing teeth on the two rotating shafts are circumferentially spaced and staggered, and at the same time, it is ensured that the crushing teeth on the two rotating shafts rotate synchronously, so that when viewed axially, the crushing teeth on one side extend into the grooves of the crushing teeth on the other side.

[0043] Arc-shaped inner walls that are clearance-matched with the outer contour of the crushing roller assembly are formed on both sides of the crushing chamber.

[0044] A clearance is formed between the arc-shaped inner wall and the outside of the crushing teeth, and a part of the feed can be crushed.

[0045] A number of crushing cones are arranged on the inner wall. Through the cooperation of the crushing cones on the arc-shaped inner wall and the crushing teeth, the crushing effect is improved.

[0046] The conveying device includes: a conveying pipeline, a spiral body and a driving mechanism.

[0047] Both ends of the conveying pipeline are respectively communicated with the bottom end of the screen and the upper part of the crushing roller assembly. The spiral body is arranged in the conveying pipeline, and the driving mechanism is connected to the end of the spiral body and is located outside the conveying pipeline for driving the spiral body to rotate and feed.

[0048] Specifically, the conveying pipeline includes: a vertical section and a bent section.

[0049] The spiral body is accommodated in the vertical section, the bent section is connected to the top of the vertical section, and the end of the bent section is inclined downward and communicated with the housing and is located above the crushing roller assembly. When the material is sent to the top of the vertical section, it can slide from the inclined bent section into the upper part of the crushing roller assembly for re-crushing.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
