[0002] Rubber has a wide range of applications in our daily life. During the processing of rubber, plastic refining is required. Plastic refining refers to changing the properties of raw materials through mechanical destruction, improving the plasticity of the rubber compound, enhancing the fluidity of the rubber compound, and increasing the adhesiveness of the rubber compound.

[0003] In the existing raw rubber plastic refining device, due to the single cutting method, the cutting of raw rubber molecular chains is uneven, affecting the quality of the rubber compound.

[0021] 1. The present invention installs and places the crushing structure and the screening structure through the installation structure provided on the bottom plate. Further, through the partition plate, it is convenient to seal the lifting raw materials in the inner cavity of the crushing structure. Through the crushing structure on the installation structure, during use, the raw rubber materials are cut by the crushing knives, thereby cutting the molecular chains of the raw rubber materials, cutting off the raw rubber molecular chains, making the plasticity of the raw rubber uniform, and finally obtaining rubber materials with uniform quality. Through the gear set on the crushing structure, during use, through the meshing of the driving gear, the first transmission gear, and the second transmission gear with each other, the adjacent two crushing knives rotate towards each other, thereby realizing repeated cutting of the raw rubber that does not meet the use size. Through the sealing structure on the crushing structure, during use, the inner cavity of the crushing frame is sealed. Further, through the rotation of the sealing flap, it is convenient to place the raw rubber in the inner cavity of the crushing frame, providing convenience for the subsequent processing of the raw rubber, such as cutting, plasticating, etc., in terms of the entry operation. Through the screening structure on the installation structure, during use, through the mutual sliding between the longitudinal screening rods, the size of the cut raw rubber is screened under the cooperation of the transverse screening rods. Further, the movement direction of the screened qualified raw rubber materials is guided through the material guiding groove, and then the lifting size of the cut raw rubber is limited. The screening gap is adjusted as needed to ensure that the raw rubber meeting the size requirements enters the next process. Through the gap adjustment structure on the crushing structure, during use, the gap between the longitudinal screening rods is made the same through the sliding rod and the adjusting rod. Further, the gap between the longitudinal screening rods is adjusted under the action of the central positioning rod and the adjusting rod by the adjusting drive structure.

[0022] 2. The present invention installs and places the stirring structure through the lifting structure on the bottom plate.

Through the stirring structure on the lifting structure, during use, the raw rubber materials in the inner cavity of the plasticating structure are stirred and mixed in multiple directions simultaneously, so that the raw materials can fully contact the air and the heat on the plasticating structure. Through the stirring drive structure on the bottom plate, during use, the plasticating structure is positioned and placed. Further, the driving force of the worm wheel is transmitted to the driving stirring rod through the base on the plasticating structure, thereby realizing the rotation of the driving stirring rod and the driven stirring rod. Through the plasticating structure on the stirring drive structure, during use, the raw rubber materials in the inner cavity of the sealing frame are heated through the electric heating module and the sealing frame. Further, the driving force of the stirring drive structure is transmitted to the stirring structure through the rotating block and the clamping block, thereby heating and stirring and mixing the raw rubber materials in the inner cavity of the plasticating structure, making the raw materials evenly heated and adjusting the viscosity of the raw rubber.

[0045] Further, the stirring structure 9 includes a stirring ring 91 rotatably connected to the inner cavity of the placing plate 83.

The adjusting gears 92 are meshed with the adjusting tooth ring 84. The middle part of the inner cavity of the stirring ring 91 is fixedly connected with a driving stirring rod 94. A groove is formed in the middle of the lower end surface of the driving stirring rod 94. Through the stirring structure 9 on the lifting structure 8, during use, the raw rubber materials in the inner cavity of the plasticating structure 11 are stirred and mixed in multiple directions at the same time, so that the raw materials can fully contact with the air and the heat on the plasticating structure 11.

[0046] Further, the stirring driving structure 10 includes a worm gear 101 rotatably connected to the middle part of the upper end surface of the bottom plate 1. A clamping block 102 is fixedly connected to the upper end surface of the worm gear 101. A worm 103 is rotatably connected to the upper end surface of the bottom plate 1 on one side of the worm gear 101 through a bracket. A driving motor 104 is fixedly connected to the upper end surface of the bottom plate 1 on one side of the worm 103. The front end surface rotating shaft of the worm 103 penetrates through the bracket and is fixedly connected to the output end of the driving motor 104. Through the stirring driving structure 10 on the bottom plate 1, during use, the plasticating structure 11 is positioned and placed, and then the driving force of the worm gear 101 is transmitted to the driving stirring rod 94 through the base 111 on the plasticating structure 11, so as to realize the rotation of the driving stirring rod 94 and the driven stirring rods 93.

[0047] The plasticating structure 11 is placed on the base 111 on the upper end surface of the clamping block 102. Electric heating modules 112 are fixedly connected to the four corners of the lower end surface of the base 111. A sealing frame 113 is fixedly connected to the upper end surface of the base 111. Through the plasticating structure 11 on the stirring driving structure 10, during use, the raw rubber materials in the inner cavity of the sealing frame 113 are heated through the electric heating modules 112 and the sealing frame 113, and then the driving force of the stirring driving structure 10 is transmitted to the stirring structure 9 through the rotating block 1112 and the clamping block 1113, so as to heat, stir and mix the raw rubber materials in the inner cavity of the plasticating structure 11, make the raw materials evenly heated, and adjust the viscosity of the raw rubber.

[0048] The base 111 includes a sealing plate 1111 placed on the upper end surface of the clamping block 102. A rotating block 1112 is fixedly connected to the middle part of the upper end surface of the sealing plate 1111. A clamping groove matching the clamping block 102 is formed in the lower end surface of the rotating block 1112. A clamping block 1113 matching the groove in the lower end surface of the driving stirring rod 94 is fixedly connected to the middle part of the upper end surface of the rotating block 1112.

[0049] Working principle: When working, pull the connecting rope 44. At this time, since the counterweight 43 is fixedly connected to the sealing flap 42, the sealing flap 42 moves in a circle with the hinge as the center, thereby opening the sealing flap 42 and placing the raw rubber in the inner cavity of the crushing frame 31.

[0050] When the raw rubber needs to be cut, the pulverizing motor 32 is started to rotate the output end of the pulverizing motor 32, so that the pulverizing knife 33 in the middle of the inner cavity of the pulverizing frame 31 rotates. Since the driving gear 341 is fixedly connected to the middle pulverizing knife 33, the driving gear 341 rotates. Since the driving gear 341, the transmission gear 1 342 and the transmission gear 2 343 are meshed with each other, the transmission gear 1 342 and the transmission gear 2 343 rotate in sequence, so that the two adjacent pulverizing knives 33 rotate relative to each other, thereby realizing the cutting of the raw rubber, and then realizing the cutting of the raw rubber molecular chain, making the plasticity of the raw rubber uniform, so as to obtain a rubber material with uniform quality.

[0051] When it is necessary to screen the lifting size of the cutting, the hydraulic telescopic rod 74 is started to shrink the hydraulic telescopic rod 74, so that the height of the connecting column 73 and the connecting slider 71 is lowered. At this time, due to the transmission connection between the adjusting rod 63 and the connecting slider 71, the adjusting rod 63 is close to each other under the limiting action of the sliding rod 62, thereby causing the spring between the adjusting rod 63 to shrink, further causing the longitudinal screening rods 53 to approach each other, so that the gap between the transverse screening rod 52 and the longitudinal screening rod 53 becomes smaller. Similarly, when the hydraulic telescopic rod 74 is extended, the connecting slider 71 and the connecting column 73 move upward. At this time, the adjusting rod 63 is away from each other under the elastic force of the spring between the adjusting rod 63 due to the lack of the pulling of the transmission belt 72, so that the pores between the transverse screening rod 52 and the longitudinal screening rod 53 are increased, thereby limiting the size of the raw rubber after cutting.

[0052] When the cut raw rubber is plasticized, the plasticizing structure 11 is placed above the clamping block 102, and then the lower end surface groove of the rotating block 1112 is engaged with the clamping block 102. At the same time, the raw rubber material that meets the size after cutting passes through the material guide groove 51 under the action of gravity and falls into the inner cavity of the sealing frame 113. At this time, the lifting structure 8 is started to shrink the electric telescopic rod 81, so the height of the lifting plate 82 and the placement plate 83 is reduced, so that the lower end surface groove of the active stirring rod 94 is engaged with the clamping block 1113. At this time, the electric heating module 112 is started to heat the raw rubber material cut in the inner cavity of the plasticizing structure 11.

[0053] Furthermore, start the stirring drive structure 10, causing the output end of the drive motor 104 to rotate. Thus, the worm 103 rotates. Since the worm gear 101 meshes with the worm 103, the worm gear 101 rotates, further causing the clamping block 102 to rotate. Since the clamping block 102 engages with the rotating block 1112, the rotating block 1112 and the clamping block 1113 rotate, so the active stirring rod 94 rotates. Since the active stirring rod 94 is fixedly connected to the stirring ring 91, the stirring ring 91 rotates, further causing the driven stirring rod 93 to perform a circular motion with the stirring ring 91 as the center. At the same time, since the upper end surface of the stirring ring 91 is provided with an adjusting gear 92 that meshes with the adjusting gear ring 84, the adjusting gear 92 rotates. At this time, since the adjusting gear 92 is fixedly connected to the active stirring rod 94, when the active stirring rod 94 rotates with the stirring ring 91 as the center, the active stirring rod 94 itself also rotates, thereby stirring and mixing the raw rubber material in the inner cavity of the plasticating structure 11 and making the raw material evenly heated, thus adjusting the viscosity of the raw rubber.
