Description

Technical Field

[0001] The present invention relates to the technical field of rubber and plastic recycling, and particularly to a waste rubber and plastic powder grinding and recycling device. Background Art

[0002] Rubber and plastic are the general terms for the rubber and plastic industries. They both originate from the refining process of petroleum. Although they have the same origin, their physical properties are very different during the process of being processed into final products, resulting in their different uses in the application fields. One of the most extensive applications of rubber is to manufacture tires. During the process of rubber and plastic recycling, especially for larger waste rubbers, they will go through multiple processing procedures such as crushing, cutting, and re-grinding to ensure that they can be effectively processed and reused.

[0003] For example, a "rubber and plastic powder grinding, recycling and reusing device" with the publication number of CN216578760U includes a grinding powder box body. Inside the grinding powder box body, a filter plate is vertically and rotatably connected. A number of groups of holes are opened inside the filter plate, and the front and rear ends of the filter plate are respectively rotatably connected to the inner wall of the grinding powder box body through rotating shafts.

[0004] However, in the prior art, as the rubber and plastic fragments are gradually broken into finer particles, these particles often accumulate due to gravity inside the crushing cavity or in a specific area. The occurrence of the accumulation problem will first directly affect the feeding efficiency of the crusher. When accumulation occurs near the feeding port, the newly entered rubber and plastic materials will be blocked and it is difficult to smoothly enter the crushing area, thus causing poor feeding, and even leading to equipment overload or shutdown. In addition, the accumulated powder will also block the screen or the discharge port, resulting in the inability of the qualified crushed products to be normally discharged, further aggravating the blockage of the crushing process. More importantly, the accumulation phenomenon will also have a negative impact on the crushing effect. In the accumulated state of the rubber and plastic materials, due to the mutual extrusion between particles, larger lumps or agglomerates will be formed, and these lumps are difficult to be effectively crushed, thus affecting the particle size distribution and quality of the final product. At the same time, long-term accumulation will also cause the temperature of the powder to rise, accelerate the aging and degradation of the rubber and plastic materials, produce bad odors, and even pose safety hazards.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, the cutting knife is driven to rotate by a rotating rod to quickly cut the rubber and plastic fragments into powder. As the powder accumulates, the cylinder adjusts the height of the sphere to drive the third movable block and the swing frame. The swing frame has a fixed height but a variable angle. The position of the stacking plate is adjusted as the sphere rises and falls to prevent it from contacting the bottom of the grinding bin. When the sphere rises, the stacking plate is lifted. When it falls, the stacking plate moves down to sort the powder to ensure uniform distribution. This periodic lifting promotes qualified powder to fall into the guide shell and is transported to the screening mechanism through the discharge plate. The movable rod slides in the limit frame to provide stable guidance and support for the swing frame and the third movable block, ensuring smooth overall operation. This design optimizes powder management and improves grinding and screening efficiency.

[0020] 2. In the present invention, the reduction motor drives the crank to rotate, transmits force to the second movable block through the push rod, and changes the direction of the force, so that it can reciprocate in a straight line in the limit hole to realize powder screening. During this process, the second movable block squeezes the springs on both sides to increase the movement frequency and improve the screening stability and efficiency. At the same time, the first movable block squeezes the spring driven by the crank, cooperates with the second movable block, and drives the receiving plate and the screen to reciprocate synchronously to accelerate the powder screening. The whole system uses the elasticity of the spring to achieve rapid resetting and continuous screening, ensuring the high efficiency and continuity of the screening process. This design cleverly combines mechanical transmission and spring elasticity to achieve fine screening of powder.

[0021] 3. In the present invention, the third drive motor drives the active bevel gear, which drives the driven bevel gear to rotate, and then drives the rotating column to rotate. This rotation fine-tunes the position of the first mounting frame to ensure that the cutting knife acts accurately on the rubber and plastic fragments to achieve efficient cutting and crushing. The second drive motor drives the rotating rod to rotate, driving the cutting knife to rotate at high speed, and forcefully cuts the fragments into powder. The guide frame and the slide rail cooperate closely to provide stable guidance for the first mounting frame, enhance the rigidity of the mechanism, ensure that the cutting and crushing process is smooth and reliable, and the overall design is efficient and precise, thereby improving the crushing efficiency.

Specific embodiments

[0032] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1: Refer to Figure 1 - Figure 6 As shown in the figure: The waste rubber and plastic powder recycling device includes a bottom plate 1. A second support platform 31 is fixedly installed on one side of the top of the bottom plate 1, and a first support platform 22 is fixedly connected to the other side of the top of the bottom plate 1. A first driving motor 2 is installed on the top of the first support platform 22. A crushing table 3 is installed on the top of the second support platform 31. A powder grinding mechanism 5 is installed on one side of the crushing table 3. A material pushing mechanism 7 is installed at the bottom of the powder grinding mechanism 5. A screening mechanism 6 is installed inside the second support platform 31. The screening mechanism 6 is used to screen the finished products;

[0034] The powder grinding mechanism 5 includes a powder grinding bin 51 and a rotating column 59. A driven bevel gear 591 is fixedly connected to the outer surface of the bottom end of the rotating column 59. A material guiding shell 57 is installed at the bottom of the inner cavity of the powder grinding bin 51;

[0035] The pushing mechanism 7 includes a first lifting rod 73 and two fixed plates 79. The top of the first lifting rod 73 passes through the rotating column 59, and the first lifting rod 73 is slidably connected to the rotating column 59. A sphere 731 is fixedly connected to the top of the first lifting rod 73. A third movable block 74 is movably connected to the outer surface of the sphere 731. The outer wall of the third movable block 74 is fixedly connected to two swing frames 75. The two fixed plates 79 are both fixedly connected to the outer wall of the rotating column 59. One end of one of the fixed plates 79 is fixedly connected to a limiting sleeve 78, and one end of the other fixed plate 79 is fixedly connected to a support rod 76. The top of the support rod 76 is fixedly connected to a limiting frame 761, and a movable rod 762 is slidably connected to the inner side of the limiting frame 761. The movable rod 762 is fixedly connected to the swing frame 75. The second lifting rod 77 is slidably connected to the inner side of the limiting sleeve 78. The transmission rod 771 is rotatably connected to the inner side of the top of the second lifting rod 77, and a stacking plate 772 is fixedly connected to the bottom of the second lifting rod 77.

[0036] A cylinder 71 is installed on the top of the base plate 1, and a lifting block 72 is rotatably connected to the top of the cylinder 71. The top of the lifting block 72 is fixedly connected to the bottom of the first lifting rod 73. The top of the transmission rod 771 is rotatably connected to the inner side of one end of the swing frame 75, and one end of the transmission rod 771 abuts against the rotating column 59.

[0037] In this embodiment, during the fine operation of the grinding mechanism 5, the rotating rod 541 drives the multiple cutting blades 55 on its outer surface to rotate at a high speed, thereby quickly and effectively cutting the rubber and plastic fragments into fine powder.

[0038] As the powder is continuously produced and accumulated. The cylinder 71 adjusts the height of the sphere 731 by controlling the lifting and lowering of the first lifting rod 73. The lifting and lowering of the sphere 731 not only changes its own height, but also drives the movement of the third movable block 74. Next, a swing frame 75 is fixed in height under the joint action of the limit frame 761 and the movable rod 762, but the angle can be changed freely. This design enables one end of the other swing frame 75 to be lifted when the sphere 731 rises, and then the second lifting rod 77 is driven to slide inside the limit sleeve 78 through the transmission rod 771. The height of the stacking plate 772 changes so that it no longer contacts the bottom of the inner cavity of the grinding bin 51.

[0039] On the contrary, when the ball 731 descends, the two swing frames 75 restore the equilibrium state under the action of gravity. At this time, the second lifting rod 77 and the stacking plate 772 begin to move downward to push and sort the accumulated rubber and plastic powder. This periodic lifting movement not only ensures the uniform distribution of the powder, but also allows the powder that meets the requirements to fall smoothly into the guide shell 57 and be transported to the screening mechanism 6 through the discharge plate 571 for the final screening process.

[0040] During the entire powder material management process, the sliding of the movable rod 762 inside the limit frame 761 plays a crucial guiding and supporting role. It not only ensures the smooth movement of the swing frame 75 and the third movable block 74.

[0041] Embodiment 2: Figure 8 and Figure 9 As shown, the screening mechanism 6 includes a second mounting frame 61. Two limit holes 62 are provided at the top of the second mounting frame 61. A first movable block 651 is slidably connected inside one of the limit holes 62, and a second movable block 671 is slidably connected inside the other limit hole 62. A movable frame 67 is fixedly connected to the top of the second movable block 671. A screen mesh 66 is fixedly connected to the top of the movable frame 67. A receiving plate 65 is installed inside the movable frame 67. The bottom of the receiving plate 65 is fixedly connected to the first movable block 651. Two springs 69 are symmetrically installed in the inner cavity of the limit hole 62, and limit rods 621 are fixedly connected to both sides of the inner cavity of the limit hole 62. One end of the spring 69 is sleeved on the surface of the limit rod 621, and the other end of the spring 69 is sleeved on one end of the first movable block 651 or one end of the second movable block 671. A crank 63 is rotatably connected to the center of one side of the first movable block 651. A push rod 68 is rotatably connected to the side wall of one end of the crank 63. One end of the push rod 68 is rotatably connected to the side wall of the spring 69. A reduction motor 64 is installed on the side wall of the receiving plate 65. The output end of the reduction motor 64 is fixedly connected to the crank 63.

[0042] In this embodiment, the reduction motor 64 drives the crank 63 to perform circular motion, and then transmits the rotating force to the second movable block 671 through the push rod 68. The connection design between the push rod 68 and the second movable block 671 enables the push rod 68 to change the direction of the acting force applied to the second movable block 671 during the rotation of the crank 63. This design not only realizes the transmission of force, but also enables the second movable block 671 to perform linear reciprocating motion under the limitation of the limit hole 62, thereby realizing the screening function of the powder material.

[0043] At the same time, the extrusion of the two side springs 69 by the second movable block 671 during movement not only increases its movement frequency, but also makes the entire screening process more stable. The elastic effect of the spring 69 enables the second movable block 671 to quickly return to its original position when subjected to an external force, thereby ensuring the continuity and high efficiency of screening.

[0044] In addition, the first movable block 651 can also slide inside the limit hole 62 and squeeze the two springs 69 under the drive of the crank 63. This not only enables the first movable block 651 to work in cooperation with the second movable block 671, but also enables the receiving plate 65 to move through the elastic effect of the spring 69. In this way, the receiving plate 65 and the screen mesh 66 can perform reciprocating motion simultaneously, thereby quickly screening the powder material.

[0045] Embodiment 3: According to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, a screening port 511 is provided at the bottom of the inner cavity of the grinding bin 51, a guide shell 57 is fixedly connected to the bottom of the grinding bin 51, a discharge plate 571 is fixedly connected to one side of the guide shell 57, a mounting shell 58 is fixedly connected to the bottom of the guide shell 57, a third drive motor 593 is mounted on one side of the mounting shell 58, a driving bevel gear 592 is fixedly connected to the output end of the third drive motor 593, and the driving bevel gear 592 is meshed with the driven bevel gear 591. A support block 581 is rotatably connected to the outer surface of the bottom end of the rotating column 59, and the support block 581 is fixedly connected to the inner wall of the mounting shell 58. A first mounting frame 56 is symmetrically fixedly connected to the outer surface of the top end of the rotating column 59, a second drive motor 54 is mounted on the top of the first mounting frame 56, a rotating rod 541 is fixedly connected to the output end of the second drive motor 54, and a cutting knife 55 is fixedly connected to the outer surface of the rotating rod 541. A slide rail 52 is fixedly connected to the top of the inner cavity of the grinding bin 51, and a guide frame 53 is slidably connected to the surface of the slide rail 52, and the guide frame 53 is fixedly connected to the first mounting frame 56. The top of the crushing table 3 is fixedly connected to the feed port 4, and the output end of the first drive motor 2 is fixedly connected to the belt transmission member 21, and one end of the belt transmission member 21 is fixedly connected to the inner cutting member of the crushing table 3.

[0046] In this embodiment, when the third driving motor 593 is started, it generates a rotational force, which is transmitted to the driving bevel gear 592 to make it start to rotate. As the driving bevel gear 592 rotates, it further drives the driven bevel gear 591 to rotate, thereby causing the rotating column 59 to rotate.

[0047] The first mounting frame 56 is a key component for mounting the second drive motor 54 and the cutting blade 55. The change of its position will directly affect the cutting and crushing effect. By accurately rotating the rotating column 59, the position of the first mounting frame 56 can be finely adjusted, thereby ensuring that the cutting blade 55 can accurately act on the rubber and plastic fragments, achieving efficient and accurate cutting and crushing.

[0048] When the second driving motor 54 is started, it drives the rotating rod 541 to rotate at high speed, thereby causing the cutting blade 55 installed on the outer surface to rotate rapidly. The high-speed rotating cutting blade 55 has a strong cutting force, which can quickly cut the rubber and plastic fragments into smaller particles and further crush them into powder.

[0049] During the movement of the first mounting bracket 56, the guide bracket 53 plays a crucial guiding role. The guide bracket 53 closely cooperates with the slide rail 52 to ensure the stability and accuracy of the first mounting bracket 56 during movement. At the same time, the presence of the guide bracket 53 also enhances the overall rigidity and stability of the mechanism, making the cutting and crushing process smoother and more reliable.

[0050] Usage method and working principle of this device: When the third driving motor 593 operates, it drives the driving bevel gear 592 to rotate. As the driving bevel gear 592 rotates, the driven bevel gear 591 also rotates accordingly, thereby driving the rotating column 59 to rotate in order to adjust and control the position of the first mounting bracket 56. Utilizing the driving force of the second driving motor 54, the rotating rod 541 can be driven to rotate, so that multiple cutting blades 55 mounted on the outer surface of the rotating rod 541 can achieve high-speed rotation, quickly cutting and crushing the rubber and plastic fragments to ensure that they can be further refined into powder materials.

[0051] During the operation of the powder grinding mechanism 5, as the powder materials are continuously generated and accumulated, the air cylinder 71 is used to control the lifting action of the first lifting rod 73. When the first lifting rod 73 slides inside the rotating column 59, it drives the sphere 731 to change its height position. The lifting of the sphere 731 further drives the third movable block 74 to move. Since a swing bracket 75 is jointly restricted by the limiting bracket 761 and the movable rod 762, its height cannot be changed and it can only change the angle. Therefore, as the sphere 731 continues to rise, one end of the other swing bracket 75 will be lifted, and then drives the second lifting rod 77 to slide inside the limiting sleeve 78 through the transmission rod 771, thereby changing the height of the stacking plate 772 so that it no longer contacts the inner cavity bottom of the powder grinding bin 51.

[0052] On the contrary, when the sphere 731 descends, due to the action of gravity, the two swing brackets 75 return to the balanced state, causing the second lifting rod 77 and the stacking plate 772 to start moving downward. This action pushes and accumulates the rubber and plastic powder materials, pushing them towards the screening port 511. The qualified powder materials then fall into the inside of the guide shell 57 and are conveyed to the screening mechanism 6 through the discharge plate 571 for final screening treatment. This can avoid excessive accumulation of powder materials inside the powder grinding bin 51, thereby affecting the cutting and crushing efficiency of the cutting blades 55. At the same time, during the movement of the swing bracket 75, the movable rod 762 can smoothly slide inside the limiting bracket 761, facilitating the movement of the two swing brackets 75 and the third movable block 74.

[0053] After the powder material accumulates to the top of the screen 66, the reduction motor 64 starts to drive the crank 63 to rotate. The crank 63 makes a circular motion centered on the output end of the reduction motor 64, and the push rod 68 drives the second movable block 671 to move under the push of the crank 63. Since the second movable block 671 can only move linearly under the restriction of the limit hole 62, it makes a linear reciprocating motion inside the limit hole 62. In this process, the second movable block 671 will successively squeeze the springs 69 on both sides, increasing the frequency of its movement. At the same time, the first movable block 651 can also slide inside the limit hole 62. When the crank 63 moves through the push rod 68, the first movable block 651 will also slide under the reaction force and also successively squeeze the two springs 69. The elasticity of the springs 69 causes the material receiving plate 65 to also have corresponding movements.

[0054] Finally, with the simultaneous reciprocating movements of the material receiving plate 65 and the screen 66, the powder material is quickly screened, thereby improving the screening efficiency. The description has been revised for grammar errors to make the expression more accurate and fluent.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
