Description

Technical Field

[0001] The utility model relates to the technical field of rubber crushing, in particular to a rubber crushing machine. Background Art

[0002] With the rapid development of my country's industry, agriculture and transportation, the consumption of rubber is increasing, and there is more and more waste rubber. Since waste rubber will not decompose naturally, a large amount of waste rubber is accumulated, which not only wastes resources but also seriously pollutes the environment. Proper treatment and recycling of waste rubber can protect the environment and achieve sustainable development. In daily life, a large number of rubber products are discarded, which will cause waste of resources and pollute the environment. The waste rubber can be crushed by mechanical crushing, and the crushed rubber can be recycled and reused. Nowadays, rubber crushers are often used for recycling and crushing waste rubber, which uses a combination of cutter wheels to crush waste rubber such as tires, hoses, rubber shoes, etc. for recycling and reuse.

[0003] However, some existing rubber crushing equipment has the following problems: when encountering larger rubber products such as tires or a large number of rubber products piled into the hopper, multiple pieces are easily squeezed and stuck in the hopper, requiring manual unblocking, which is time-consuming and labor-intensive and may pose a safety hazard.

[0004] Therefore, a rubber pulverizer is proposed. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. 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 those skilled in the art without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 , the utility model provides a technical solution:

[0022] A rubber crusher includes a frame 101, which is an integral frame structure for supporting the entire device. The frame 101 is provided with a first crushing mechanism and a second crushing mechanism that work synchronously from top to bottom. The first crushing mechanism includes a large crushing barrel 201 connected to the frame 101 and a first crushing knife group arranged in the large crushing barrel 201. The cross section of the large crushing barrel 201 is circular, and a plurality of discharge ports 202 are provided at intervals at the bottom of the large crushing barrel 201. The rubber particles that are initially crushed by the first crushing knife group can fall into the second crushing mechanism through the plurality of discharge ports 202 for secondary crushing.

[0023] In some implementations of the present embodiment, the central axis of the large crushing barrel 201 is parallel to the horizontal direction, and a plurality of annular grooves 203 are evenly spaced on the inner wall of the large crushing barrel 201; the first crushing knife group includes a first rotating shaft 204 rotatably connected to the frame 101 and a plurality of first blades 205 evenly spaced on the first rotating shaft 204, the central axis of the first rotating shaft 204 is colinear with the central axis of the large crushing barrel 201, and the first rotating shaft 204 is transmission-connected to the second crushing mechanism; the plurality of first blades 205 correspond one-to-one to the plurality of annular grooves 203, any first blade 205 is an elliptical structure, and the length of the long semi-axis of any first blade 205 is greater than the inner diameter of the large crushing barrel 201, and less than the sum of the inner diameter of the large crushing barrel 201 and the depth of the annular groove 203.

[0024] The first blade 205 is designed as an elliptical structure. On the one hand, after the first blade 205 is installed in the large crushing barrel 201, there is a gap between its edge and the inner wall of the large crushing barrel 201, which is convenient for temporarily storing the rubber to be cut in the large crushing barrel 201; on the other hand, the first blade 205 cooperates with the annular groove 203 to facilitate the cutting of the rubber; on the third hand, when the "long end" of the first blade 205 is inserted into the annular groove, it can give the rubber a thrust, pushing the rubber to the inner wall of the large crushing barrel 201, thereby playing a dredging role, and no manual dredging is required. At the same time, this thrust forms a cutting impact force, which still has a good cutting effect when cutting harder rubber. The rubber particles cut by the first crushing mechanism fall into the second crushing mechanism through a number of discharge ports 202 for secondary cutting and crushing.

[0025] Specifically, the second crushing mechanism includes a second crushing knife group and small crushing barrels 301 that are connected to a plurality of discharge ports 202 in a one-to-one correspondence. The second crushing knife group includes a second rotating shaft 302 rotatably connected to the frame 101 and a plurality of crushing knife groups spaced apart on the second rotating shaft 302. Any crushing knife group is located in the corresponding small crushing barrel 301. Any crushing knife group includes a plurality of second blades 303 spaced apart evenly. There is a gap between any second blade 303 and the inner wall of the small crushing barrel 301. The second rotating shaft 302 is transmission-connected to the first rotating shaft 204.

[0026] The second pulverizing mechanism is designed as a plurality of independent pulverizing units. The rubber particles cut by the first pulverizing mechanism can fall into each small pulverizing barrel 301 for small batch cutting, which can reduce the cutting pressure of the second pulverizing mechanism.

[0027] When the second blades 303 perform secondary crushing on the rubber, the second blades 303 will rotate. Since there is a gap between two adjacent second blades 303, the rubber particles that are secondary crushed are easily accumulated between the two adjacent second blades 303, thereby causing blockage. Therefore, in order to reduce the blockage rate between two adjacent second blades 303, a plurality of levers 401 are evenly spaced in any small crushing barrel 301, and any lever 401 is located between two adjacent second blades 303. The presence of the lever 401 when the second blades 303 rotates makes it difficult for the crushed rubber particles to accumulate between two adjacent second blades 303.

[0028] In order to realize the synchronous rotation of the first rotating shaft 204 and the second rotating shaft 302, the central axis of the second rotating shaft 302 is parallel to the central axis of the first rotating shaft 204, and the same end of the first rotating shaft 204 and the second rotating shaft 302 are both provided with a pulley 501, and the two pulleys 501 are connected by a belt 502; the end of the first rotating shaft 204 away from the pulley 501 is connected by a driving motor 503. This design enables one driving motor 503 to drive the two rotating shafts to rotate, realizing a lightweight design. In other implementations of this embodiment, the transmission mechanism between the first rotating shaft 204 and the second rotating shaft 302 can also use a gear mechanism to realize power transmission.

[0029] In order to facilitate feeding, a feeding port 601 is provided on the top of the large crushing barrel 201. Figure 1 As shown, the feeding port 601 is designed to be long and strip-shaped, and extends along the extension direction of the large crushing barrel 201. This design can pour a large amount of rubber at one time; on the other hand, it can also easily handle the long strip of rubber.

[0030] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
