Description

Technical Field

[0001] This utility model relates to the technical field of rubber product manufacturing equipment, specifically to a rubber particle raw material mixing equipment for rubber product manufacturing. Background Technology

[0002] In the production of rubber products, it is necessary to thoroughly mix different types and specifications of rubber granules to ensure that the subsequently produced rubber products have uniform properties and stable quality. Currently, most rubber granule raw material mixing equipment on the market adopts a traditional stirring structure, which achieves raw material mixing by rotating a stirring paddle in a mixing tank.

[0003] However, these traditional mixing equipment have significant shortcomings. On the one hand, traditional mixing chambers are mostly cylindrical or rectangular in shape, which can easily lead to dead zones in the flow of rubber particles during the mixing process due to structural limitations. This results in some raw materials not being fully mixed, causing uneven mixing and affecting the quality of subsequent rubber products. On the other hand, traditional stirring methods rely solely on the unidirectional rotation of the stirring paddle to move the raw materials, resulting in low mixing force and efficiency. Relying on the unidirectional rotation of the stirring paddle to move the raw materials can also cause damage and breakage of rubber particles, affecting the final product. Furthermore, a long mixing time is required to achieve a basic mixing effect, which is not conducive to improving the production efficiency of rubber products.

[0004] Therefore, designing a rubber particle raw material mixing equipment that can avoid mixing dead zones and improve mixing uniformity and efficiency has become an urgent problem to be solved in the current rubber product manufacturing industry. Utility Model Content

[0005] This utility model aims to solve the above-mentioned technical problems by providing a rubber particle raw material mixing device for rubber product manufacturing.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0007] A rubber particle raw material mixing device for rubber product manufacturing includes a base frame, on which a mixing box for mixing rubber particles is installed; the mixing box has a rhomboid structure, and a mixing cavity is opened inside the mixing box. The upper and lower ends of the mixing cavity are connected to storage boxes, and a connecting pipe for intensifying the mixing of rubber particles is installed on the inner side of the mixing box; a drive device for driving the mixing box to rotate is installed on the base frame.

[0008] Furthermore, the connecting pipes are arranged in two sets, which are cross-connected and each end is connected to the mixing chamber. The cross-connected sets of pipes allow the rubber particles to form multi-directional flow channels within the mixing chamber during the rotation of the mixing box, breaking the single flow trajectory, further intensifying the collision and mixing between the raw materials, and improving the mixing effect.

[0009] Furthermore, multiple sets of separating rods are installed inside the mixing chamber. These separating rods can break up clumps or aggregates of rubber particles within the mixing chamber, preventing raw material agglomeration from affecting the uniformity of mixing. Simultaneously, the separating rods can change the flow direction of the raw materials when the mixing chamber rotates, increasing the complexity of the material's movement and thus improving mixing efficiency.

[0010] Furthermore, support frames are installed on both sides of the base frame and on both sides of the mixing chamber. Each set of support frames includes a fixed frame that is positioned opposite to the base frame, and a baffle is installed between the two fixed frames. The support frames, through the stable connection between the fixed frames and the base frame, and the support provided by the baffle for the mixing chamber, provide a stable support structure for the rotation of the mixing chamber, ensuring that the mixing chamber will not shift or shake during high-speed rotation, thereby improving the stability and safety of the equipment operation.

[0011] Furthermore, the driving device includes a drive motor, the output end of which is equipped with a rotating shaft. A baffle is connected to the outer side of the rotating shaft via a bearing, and the other end is fixedly connected to one end of the mixing chamber. A linkage shaft is installed at the other end of the mixing chamber, and the outer side of the linkage shaft is connected to another baffle via a bearing. After the drive motor starts, it drives the mixing chamber to rotate around the axis of the rotating shaft and the linkage shaft via the rotating shaft. The linkage shaft rotates synchronously with the mixing chamber under the support of the bearings on the baffle, ensuring that the mixing chamber can achieve stable and smooth 360° rotation, providing power for the thorough mixing of rubber particles.

[0012] Furthermore, a motor bracket is mounted on the base frame, and the drive motor is fixedly connected to the motor bracket by bolts. The motor bracket provides a stable mounting base for the drive motor, and the bolt fixing method not only facilitates the installation and disassembly of the drive motor, but also ensures that the drive motor will not shift due to vibration during operation, thus ensuring the stable operation of the drive device.

[0013] Furthermore, the storage box is equipped with a feed port for rubber particles. This feed port facilitates the addition of rubber particle raw materials into the mixing equipment and the discharge of the mixed material after mixing, simplifying the operation process and improving production convenience.

[0014] With the above structure, this utility model has the following advantages:

[0015] 1. This utility model sets the mixing chamber into a rhomboid structure and drives the mixing chamber to rotate with a driving device, so that the rubber particles can make a circular motion without dead angles along the inclined inner wall of the rhomboid structure in the mixing chamber. This effectively avoids the mixing dead angles caused by structural problems in traditional mixing equipment and significantly improves the mixing uniformity of rubber particle raw materials.

[0016] 2. The two sets of connecting pipes that cross each other inside the mixing box, as well as the multiple sets of separating rods inside the mixing chamber, can, during the rotation of the mixing box, form a multi-directional flow channel through the connecting pipes, intensifying the collision of raw materials; on the other hand, the separating rods can break up the clumps of raw materials and change the flow direction of the raw materials, which greatly improves the mixing efficiency of the raw materials, shortens the mixing time, and helps to improve the overall production efficiency of rubber products.

[0017] 3. The support frames on both sides of the base frame provide stable support for the mixing tank through the fixing frame and baffle. The drive motor is fixed to the base frame through the motor bracket, which ensures the stability and safety of the equipment during operation, reduces the probability of equipment failure due to vibration or displacement, and extends the service life of the equipment.

In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0024] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0025] The present invention will now be described in further detail in conjunction with the full text.

[0026] Combined with appendix Figures 1-2 A rubber particle raw material mixing device for rubber product manufacturing includes a base frame 1. The base frame 1, as the basic support component of the entire device, is made of high-strength steel to ensure the overall load-bearing capacity and stability of the device. A mixing chamber 2 for mixing rubber particles is installed on the base frame 1. The mixing chamber 2 has a rhomboid structure. The rhomboid design allows the rubber particles inside the mixing chamber 2 to slide freely along the inclined inner wall of the rhombus when rotating, avoiding the dead flow corners that are easily generated in traditional rectangular or cylindrical mixing chambers.

[0027] Specifically, the mixing chamber 2 has a mixing cavity 3 inside, which is the main space for mixing rubber particles. The upper and lower ends of the mixing cavity 3 are connected to a storage box 4, which is used to temporarily store the raw materials to be mixed and the mixed materials after mixing. The storage box 4 is equipped with a material inlet 12 for inlet and outlet of the rubber particles. The material inlet 12 can be detachable by using a pipe opening and a threaded cap. Workers can add raw materials to the storage box 4 through the material inlet 12. The raw materials enter the mixing cavity 3 under gravity. After mixing, the mixed raw materials are discharged through the material inlet 12.

[0028] When this invention is specifically implemented, such as Figure 2 As shown, the mixing chamber 2 is equipped with two sets of connecting pipes 5 to enhance the mixing of rubber particles. These two sets of connecting pipes 5 are cross-connected and their ends are connected to the mixing chamber 3. When the mixing chamber 2 rotates, some of the rubber particles in the mixing chamber 3 flow along the inner wall of the mixing chamber 3, while the rest enter the cross-connecting connecting pipes 5. Through the connecting pipes 5, a multi-directional material flow path is formed in the mixing chamber 3, allowing the rubber particles to collide and mix more fully, effectively improving the mixing effect.

[0029] Specifically, multiple sets of separating rods 7 are installed inside the mixing chamber 3. The separating rods 7 are evenly distributed inside the mixing chamber 3. When rubber particles flow in the mixing chamber 3, the separating rods 7 can break up clumps or aggregates of rubber particles, preventing raw materials from clumping and affecting the uniformity of mixing. At the same time, the separating rods 7 can also change the direction of movement of rubber particles during their flow, increasing the complexity of the movement of raw materials and further improving mixing efficiency.

[0030] When this invention is specifically implemented, such as Figure 1 and Figure 2 As shown, a drive unit 6 for rotating the mixing tank 2 is installed on the base frame 1. Support frames 8 are installed on both sides of the mixing tank 2 on the base frame 1. Each set of support frames 8 includes a fixed frame 9 that is disposed opposite to the base frame 1. A baffle 10 is installed between the two fixed frames 9. The fixed frames 9 of the support frames 8 are fixedly connected to the base frame 1 by welding to ensure the stability of the support frames 8. The baffle 10 is connected to the fixed frame 9 by bolts to facilitate later maintenance and replacement.

[0031] Specifically, the drive unit includes a drive motor 601, which is a three-phase asynchronous motor with stable speed and sufficient torque to meet the power requirements for the rotation of the mixing tank 2. A rotating shaft 602 is mounted on the output end of the drive motor 601. The outer side of the rotating shaft 602 is connected to a baffle 10 via a bearing, and the other end is fixedly connected to one end of the mixing tank 2. A linkage shaft 11 is mounted on the other end of the mixing tank 2, and the outer side of the linkage shaft 11 is connected to another baffle 10 via a bearing. The bearing configuration reduces the frictional resistance between the rotating shaft 602 and the linkage shaft 11 during rotation, ensuring smooth rotation of the mixing tank 2.

[0032] Specifically, a motor bracket 603 is installed on the base frame 1, and the drive motor 601 is fixedly connected to the motor bracket 603 by bolts. The motor bracket 603 can provide stable support for the drive motor 601, and the bolt fixing method facilitates the installation, disassembly and maintenance of the drive motor 601.

[0033] The working principle of this utility model:

[0034] When using this rubber particle raw material mixing equipment, the operator first adds the rubber particle raw material to be mixed into the mixing chamber 3 through the material inlet 12 on the storage tank 4. After the raw material is added, the drive motor 601 is started. The drive motor 601 drives the rotating shaft 602 to rotate, and the rotating shaft 602 drives the mixing tank 2 to rotate around the axis of the rotating shaft 602 and the linkage shaft 11. The linkage shaft 11 rotates synchronously with the mixing tank 2 under the support of the bearing of the baffle 10.

[0035] During the rotation of mixing chamber 2, due to its rhomboid structure, the rubber particles circulate along the inclined inner wall of the rhombus within mixing chamber 3, avoiding the formation of mixing dead zones. Simultaneously, the two sets of interconnected pipes 5 on the inner side of mixing chamber 2 allow some rubber particles to flow within these pipes, forming multidirectional material flow paths and intensifying collisions and mixing between the rubber particles. Multiple sets of separating rods 7 within mixing chamber 3 break up clumps of rubber particles and change their flow direction, further improving the uniformity and efficiency of mixing.

[0036] Once the rubber particle raw materials are mixed to meet the production requirements, the drive motor 601 is turned off, the mixing box 2 stops rotating, and the workers then discharge the mixed rubber particle raw materials through the material outlet 12, completing one mixing operation.

[0037] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
