Description

Technical Field

[0001] The utility model relates to the technical field of rubber waste recycling, and particularly relates to a feeding mechanism and a rubber waste recycling and crushing device thereof. Background Technique

[0002] Rubber products are widely used in many fields. In order to advocate economic and environmental protection, waste rubber after use is generally recycled, and rubber crushing processing is an essential step in the process of waste rubber recycling.

[0003] In the prior art, for example, a rubber recycling crushing device disclosed in the utility model patent with the authorization announcement number CN214521328U. For the rubber with large particles after crushing in this device, it can enter the feeding box through the feeding pipe. The second motor is controlled to rotate by the controller, and the rotation of the second motor drives the spiral blade to rotate, and the rubber particles in the feeding box are conveyed into the crushing box through the discharge pipe for continuous crushing, and the rubber with larger particles after crushing is fed again to improve the uniformity of rubber crushing.

[0004] However, the following problems still exist in the above-mentioned crushing device during use: when the large-particle rubber in the filter box enters the feeding box through the discharge pipe, some small-particle rubbers that meet the crushing size will also enter the feeding box through the discharge pipe due to inertia for re-feeding. This leads to the feeding of small-particle rubbers that meet the crushing size being useless work during the secondary feeding process, increasing energy consumption and not meeting the processing concept of energy conservation and consumption reduction. Therefore, a feeding mechanism and a rubber waste recycling and crushing device thereof are proposed. Content of the Utility Model

Detailed implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0023] The present invention provides as Figures 1-3A feeding mechanism as shown includes a feeding pipe shell 100, and also includes a feeding pipeline 102, a screen pipe 106 and an auxiliary pipeline 103. There is a feeding mechanism 200 inside the feeding pipe shell 100. The screen pipe 106 is made by winding a stainless steel wire mesh into a circular tube shape. The aperture diameter of the screen holes on it is larger than that of fine-grained rubber and smaller than that of coarse-grained rubber. At the top of the outer wall of the feeding pipe shell 100, there is a discharge pipeline 101 fixedly connected and communicating with the inner cavity of the feeding pipe shell 100. The end far from the feeding pipe shell 100 extends in an obliquely downward direction. In this way, the discharge pipeline 101 can be inclined downward. When the feeding mechanism 200 lifts the rubber particles at the bottom position of the feeding pipe shell 100 to the port position of the discharge pipeline 101, the discharge can be carried out by using the slope of the discharge pipeline 101, so that the rubber particles can enter the crushing device along the discharge pipeline 101 for re-crushing operation. The feeding pipeline 102 is fixedly connected to the bottom of the outer wall of the feeding pipe shell 100. There is a feeding channel 104 in the middle of the feeding pipeline 102, which communicates with the inner cavity of the feeding pipe shell 100. There is a sorting channel 105 on the inner wall of the feeding channel 104. The screen pipe 106 is fixedly arranged in the inner cavity of the sorting channel 105, and the inner side of the screen pipe 106 is communicated with the feeding channel 104. There is a discharge port 107 on the outer wall of the feeding pipeline 102, which communicates with the end of the sorting channel 105. One end of the auxiliary pipeline 103 is fixedly connected and communicated with the discharge port 107. The end of the feeding pipeline 102 far from the feeding pipe shell 100 is communicated with the filter box at the bottom discharge port of the crushing device. The filtered rubber particles can enter the feeding pipe shell 100 by using the slope of the feeding pipeline 102. Among them, the rubber particles enter from the inner side of the screen pipe 106. By using the screening function of the screen pipe 106, the fine-grained rubber particles are screened out and fall into the sorting channel 105, and slide to the end position of the sorting channel 105 by using the slope of the feeding pipeline 102, and then enter the auxiliary pipeline 103 from the discharge port 107 and can be discharged through the auxiliary pipeline 103, so as to avoid the fine-grained rubber particles from entering the feeding pipe shell 100 from the feeding pipeline 102, reduce unnecessary work and lower energy consumption.

[0024] It should be noted that the outer diameter length of the screen pipe 106 is smaller than the diameter length of the sorting channel 105, and the inner diameter length of the screen pipe 106 is equal to the diameter length of the feeding channel 104. In this way, the gap between the sorting channel 105 and the screen pipe 106 can meet the sliding of the fine-grained rubber particles. The length of the sorting channel 105 is smaller than the length of the feeding channel 104, and both ends of the sorting channel 105 are not communicated with both ends of the feeding pipeline 102, so that the rubber particles flowing out from the side wall of the filter box on the crushing device can enter from the inner side of the screen pipe 106, and then the screened fine-grained rubber particles can enter the position between the sorting channel 105 and the screen pipe 106 for subsequent discharge;

[0025] Furthermore, the end of the feed pipe 102 away from the feeding shell 100 extends in an obliquely upward direction, and the end of the auxiliary pipe 103 away from the feed pipe 102 extends in an obliquely downward direction. The inertial effect generated by the slope can be utilized to enable the rubber particles to achieve automatic blanking in the feed pipe 102 and the auxiliary pipe 103.

[0026] In a preferred embodiment, the feeding mechanism 200 includes a rotating shaft 201 rotatably disposed in the inner cavity of the feeding shell 100. A spiral blade 202 is fixedly connected to the outer wall of the rotating shaft 201. A feeding motor 203 is fixedly connected to the top end of the feeding shell 100. The output shaft of the feeding motor 203 penetrates through the inner cavity of the feeding shell 100 and is drivingly connected to the top end of the rotating shaft 201. After the feeding motor 203 is connected to an external power source, it drives the rotating shaft 201 to rotate. The rotating shaft 201 drives the spiral blade 202 to rotate, and the rubber particles located at the bottom of the feeding shell 100 can be gradually lifted upward to the discharge pipe 101 to feed the crushing device.

[0027] On the other hand, the present utility model also provides a rubber waste recycling and crushing device, including the above-mentioned feeding mechanism.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
