[0002] As we all know, rubber particles are granular raw materials formed after colloid processing. They are mainly composed of various polymers, which are formed by a large number of repeating units (monomers) connected by polymerization reactions. The rubber particle production line is an auxiliary device for realizing rubber particle injection molding production.

[0003] After searching, the Chinese patent application number CN216544626U and the patent application number CN202278694U respectively disclose a rubber pellet flower-shaped molding die and a molding mold for making barbell plates from recycled rubber pellets, wherein the former is roughly described as including a die body and an extruder, a die cavity is arranged in the die body, the die cavity includes a plurality of independent chambers and a merging chamber connected to each chamber, one end of the die body is arranged as a discharge end, the discharge end is provided with a discharge port connected to the merging chamber, the die body is arranged in sequence according to the order of each chamber-merging chamber-discharge port, the chambers and the merging chambers are respectively connected to the corresponding extruders, and the extruder is provided with an injection piece for injecting the extruded material into the die body, The die head body is provided with a feed port corresponding to the extruder to connect the injection part with each chamber and the merging cavity. When in use, it can process multi-color granules, solving the problem of single color of granules made by existing granule molds. The latter can be roughly described as including a mold body, a mold cover is provided on the mold body, and an annular cavity is formed inside after the mold body and the mold cover are closed. The upper and lower surfaces of the outer and inner sides of the annular cavity are provided with an outer annular groove and an inner annular groove respectively. The interval area between the inner annular groove and the outer annular groove is evenly distributed with three fan-shaped concave platforms, and the three fan-shaped concave platforms are adjacent to each other at an interval of 60 degrees. When in use, the annular contact surface of the mold body and the outer edge of the mold cover is provided with an injection and pressing sub-platform structure to increase the molding pressure of the product in the mold cavity, which is beneficial to the molding of the product.

[0025] The servo motor 13, the electric drive rod 14 and the first electric telescopic rod 46 in this embodiment are all conventional devices purchased on the market and known to those skilled in the art. In the present invention, we only use them without improving their structure and function. For those skilled in the art, their setting method, installation method and electrical connection method only need to be debugged and operated according to the requirements of their instruction manual, and will not be described in detail here.

[0026] In summary, the working principle of the granule production line is as follows: when in use, the granule production line is first installed at the desired location. During the installation process, the guide butt joint pipe 2 should be installed corresponding to the extrusion head of the matching extruder, so that the raw materials of the granules output by the extruder can be auxiliary guided by the guide butt joint pipe 2, and the main frame 1 is installed relative to the extruder, so that the axis of the connecting butt joint pipe 6 on the main frame 1 coincides with the axis of the guiding butt joint pipe 2. During actual operation, the displacement drive of the sliding table 5 relative to the main frame 1 can be realized by powering on the first electric telescopic rod 46. During the movement of the sliding table 5, the synchronous movement of the connecting butt joint pipe 6 is realized through the cover shell 8, so that the relative connection and separation state of the guiding butt joint pipe 2 and the connecting butt joint pipe 6 can be controlled. When the connecting butt joint pipe 6 approaches and contacts the guiding butt joint pipe 2 and is connected, the raw materials in the guiding butt joint pipe 2 can be transported to the upper elbow 7 through the guidance of the connecting butt joint pipe 6, and are sequentially guided through the main guide hole 23 and the auxiliary diversion hole 24 in the diversion flow 22. and diversion and enter multiple die end cavities connected to the auxiliary diversion hole 24, and finally form filling and pressure holding in the mutually cooperating die end cavities, the first half die cavity 25 and the second half die cavity 26 to realize auxiliary molding of the rubber particles. Along with the aforementioned injection molding, the servo motor 13 is started. A driving gear is installed on the output shaft of the servo motor 13. The driving gear is meshed with an internal gear ring. The internal gear ring is fixedly connected to the rotating frame 10. Through the meshing transmission of the driving gear and the internal gear ring, the servo motor 13 is powered on in stages to realize the rotation drive of the rotating frame 10 relative to the cover shell 8. During the rotation of the rotating frame 10, multiple die end cavity groups 12 will rotate sequentially into the feeding area of ​​the upper elbow 7 to realize the sequential injection of raw materials into multiple whole mold bodies. The bending direction of the upper elbow 7 is upward, so the whole mold body that rotates into the top of the multiple whole mold bodies is in the raw material injection state, and the whole mold body that rotates into the bottom of the multiple whole mold bodies is in the unloading state. Considering the effect of gravity, it is convenient to assist in demolding and falling of the solidified rubber particles.

[0027] Furthermore, during the rotation of the rotating frame 10, the synchronous rotation movement of multiple synchronous drive plates 35 will be realized. The rotation of the synchronous drive plate 35 to the lowest position will cause the round head plate 44 to enter the notch area 45 on the synchronous drive plate 35. Then, the electric drive rod 14 is powered on to realize the movement of the round head plate 44 in the direction away from the connecting butt joint 6. Under the pulling effect of the round head plate 44 on the synchronous drive plate 35, the synchronous drive plate 35 can be moved away from the rotating frame 10. The movement of the synchronous drive plate 35 drives the first traction rod 36 and the second traction rod 37 connected thereto to move synchronously. The first traction rod 36 and the second traction rod 37 respectively drive the two transmission circular shafts 40 to move. The first transmission rod 38 and the second transmission rod 39 are driven by the two round head plates 44 to move. The first transmission rod 38 and the second transmission rod 39 respectively realize the movement and push of the first mold body 3 and the second mold body 4, that is, the first mold body 3 and the second mold body 4 in the whole mold body at the bottom are rotated to move downward synchronously. Since the interior of the mold base cavity 11 is a vertical surface structure and the exterior is a gradually expanding surface structure, the first mold body 3 and the second mold body 4 moving downward will first maintain a relatively contact closed state and move under the guidance of the vertical surface structure. In this process, the rubber particles can be assisted to be removed from the mold end cavity. When the first mold body 3 and the second mold body 4 are completely entered, When the first mold body 3 and the second mold body 4 are in the structural area of ​​the gradually expanding surface, the limiting effect of the vertical surface structure on the first mold body 3 and the second mold body 4 fails. At the same time, under the elastic pulling action of the auxiliary tension spring 21, the first mold body 3 and the second mold body 4 in the relatively contact closed state will rotate and separate relative to each other, so that the first half mold cavity 25 and the second half mold cavity 26 can be relatively rotated and opened to facilitate the demolding of the rubber particles. After the first mold body 3 and the second mold body 4 are relatively rotated and separated, the relative pushing effect of the first pair of push frames 29 and the second pair of push frames 31 formed relatively inside the two will also be reduced or even disappear. Therefore, under the elastic pushing action of the first push spring 33, the first pair of push frames 29 will form a relative position relative to the first mold body 3. The movement of the first pair of push frames 29 will drive the multiple first side push frames 30 thereon to form synchronous movement, and the moving multiple first side push frames 30 will respectively move outward relative to the multiple first half-mold cavities 25 to assist the rubber particles located in the first half-mold cavities 25 to form auxiliary outward push demolding. Similarly, under the elastic pushing action of the second push spring 34, the second pair of push frames 31 will form a relative position movement relative to the second mold body 4, and the movement of the second pair of push frames 31 will drive the multiple second side push frames 32 thereon to form synchronous movement, and the moving multiple second side push frames 32 will respectively move outward relative to the multiple second half-mold cavities 26 to assist the rubber particles located in the second half-mold cavities 26 to form auxiliary outward push demolding.

[0028] Furthermore, since the plastic pellets after injection molding are an integrated complete structure, during the demolding process, after the first half-mold cavity 25 and the second half-mold cavity 26 that cooperate with each other form a relative rotation separation, the plastic pellets with the complete structure will be in the first half-mold cavity 25 or the second half-mold cavity 26. Therefore, in the actual operation process, one of the first side push frame 30 and the second side push frame 32 will complete the auxiliary demolding of the plastic pellets. After the demolding is completed, the electric drive rod 14 controls the round head plate 44 to reset, and the pulling effect of the reset round head plate 44 on the synchronous drive plate 35 fails. Under the action of the first reset spring and the second reset spring, the first traction rod 36 and the second traction rod 37 are reset in the reverse motion. , thereby achieving the synchronous upward reset of the first mold body 3 and the second mold body 4 that have moved downward at the bottom, so that the first mold body 3 and the second mold body 4 form a whole mold body again and enter the mold base cavity 11, and then the rotating frame 10 rotates again to realize the synchronous rotation drive of multiple whole mold bodies, and then realize the alternating raw material injection and rubber pellet demolding of multiple whole mold bodies in sequence to form continuous production of rubber pellets. After the production is completed, the first electric telescopic rod 46 works to control the connection docking tube 6 to separate relative to the guide docking tube 2 to facilitate the corresponding cleaning of the extruder head on the extruder. In order to facilitate the guidance and external discharge of the rubber pellets after demolding, a guide ramp is provided on the main frame 1 and a through port is provided on the sliding table 5.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
