Description

Technical Field

[0001] The present invention relates to the field of mixing equipment, and specifically to a rubber roller raw material mixing device and method. Background Art

[0002] A rubber roller is a roller-shaped product with a metal or other material core and an outer rubber coating vulcanized. Compared with a pure metal roller, it has good elasticity and oil resistance. When processing a rubber roller, it is necessary to mix the rubber raw materials on the surface. The existing rubber roller raw material mixing devices generally have a too simple stirring structure and lack the function of turning up and down, resulting in a longer mixing time and a general mixing effect. Secondly, it is not easy to convey the rubber roller raw materials out of the device after the mixing and stirring inside the device are completed.

A first rotating shaft is connected to one side wall of the support block through a bearing. The output end of the first motor is connected to the first rotating shaft. When this technical solution is used, through the arranged support plate, mixing bin, first motor, support block, first rotating shaft, stirring frame, scraper, stirring rod, stirring plate, feeding bin and baffle, the rubber roller raw materials can be cyclically turned and stirred to fully mix the raw materials, which can effectively improve the mixing effect and shorten the mixing time. For the above technical solution, although the turning and stirring are realized, multi-directional and multi-point stirring cannot be provided during stirring, and the proportioning and feeding of materials cannot be completed during stirring, which is inconvenient in use. Summary of the Invention

The structure of the present invention is novel. When in use, after one end of the movable cylinder enters the bottom of the feeding hopper, different materials enter different positions of the barrel through the cooperation of the feeding hopper and the movable cylinder. Later, the conveying component rotates to drive the materials to turn up and down, and the conveying component cooperates with the stirring column to provide multi-point and multi-direction rapid stirring and mixing.

[0005] To achieve the above object, the present invention is realized through the following technical solutions: A rubber roller raw material mixing device, including a base, on which a fixed seat and a support seat are respectively welded. A barrel body is fixedly installed between the fixed seat and the support seat. An opening is provided at the top of the barrel body, and a movable cylinder is movably installed inside the opening. A connecting rod is welded between the movable cylinders, and a lifting mechanism is fixedly installed on the connecting rod. One end of the lifting mechanism is fixed on the barrel body. A feed barrel is movably installed at the top of the movable cylinder, and a feed hopper is fixedly installed at the top of the feed barrel.

[0010] Further, a stirring plate is fixed at the bottom of the stirring auger, one end of the conveying auger is movably installed inside the discharge pipe, and a control box is fixed on the side of the fixed seat.

The conveying motor is respectively connected to the conveying auger and the stirring auger.

[0012] A rubber roller raw material mixing method realized by using the rubber roller raw material mixing device described in claim 1 includes the following steps:

[0013] Step 1, Material preparation: First, an appropriate amount of rubber raw materials need to be prepared, including natural rubber, synthetic rubber, etc. In addition, some auxiliary materials such as vulcanizing agents, accelerators, antioxidants, etc. are also required. The selection of materials will directly affect the quality and performance of the rubber roller.

[0014] Step 2, Ratio and mixing: According to a specific formula, the rubber raw materials and auxiliary materials are mixed together. After stirring and kneading, a uniform rubber compound is formed.

[0015] Step 3, Filtering the rubber compound;

[0016] Step 4, Shaping: During the shaping process, various methods can be used, such as the laminating method and the extrusion winding method. In the laminating method, the film rolls extruded by the calender are placed on the laminating machine and wound and laminated layer by layer on the metal roll core; while in the extrusion winding method, the hot rubber strips are continuously extruded by the extruder and directly wound on the metal roll core.

[0017] Step 5, Vulcanization treatment;

[0018] Step 6, Processing and trimming.

[0019] Furthermore, after the mixing in Step 3 is uniform, a rubber compound filtering machine is used to remove impurities in the rubber compound to ensure that there are no air bubbles and impurities in the rubber compound to meet the requirements of rubber roller shaping. In Step 5, the prepared rubber roller blank is subjected to vulcanization treatment, enabling it to undergo a chemical reaction under high temperature and high pressure to increase the crosslinking density of the rubber compound, thereby improving the physical properties and chemical stability of the rubber roller.

[0020] Furthermore, after the vulcanization treatment in Step 6, the rubber roller is processed and decorated, including processes such as turning, polishing, and punching, to remove surface defects and uneven parts, enabling the rubber roller to reach the required precision and surface quality. Quality inspection is carried out on the manufactured rubber roller, including tests of indicators such as hardness, tensile strength, compression set, and thermal stability.

[0021] Advantages of the present invention:

[0022] 1. For this rubber roller raw material mixing device, when one end of the movable cylinder enters the bottom of the feed hopper, different materials enter different positions of the barrel simultaneously through the cooperation of the feed hopper and the movable cylinder. Later, the conveying component rotates to drive the materials to turn up and down, and the cooperation between the conveying component and the stirring column provides multi-point and multi-directional rapid stirring and mixing.

[0023] 2. For this rubber roller raw material mixing device, later the movable cylinder moves downward, the conveying component pushes the arc plate downward. When the arc plate moves downward, the connection hole position is opened, and the materials are pushed into the discharge pipe through the conveying auger and the stirring auger and discharged. The cooperation between the conveying auger and the discharge pipe provides driving force, effectively preventing the materials from being blocked in the discharge pipe.

[0024] 3. After one end of the movable cylinder enters the fixed hole in the later stage, the position of the conveying component is adjusted. In addition, the same material is conveyed to different positions of the barrel under the drive of the conveying component, and the rapid stirring and mixing in the later stage is completed through the conveying of the material.

Detailed Embodiments

[0034] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0035] Please refer to Figures 1 to 8 , the present invention provides a technical solution: a rubber roller raw material mixing device, including a base 1, on which a fixed seat 3 and a support seat 5 are respectively welded. A barrel 7 is fixedly installed between the fixed seat 3 and the support seat 5. An opening 12 is formed at the top of the barrel 7, and a movable cylinder 13 is movably installed inside the opening 12. A connecting rod 15 is welded between the movable cylinders 13, and a lifting mechanism 16 is fixedly installed on the connecting rod 15. The lifting mechanism 16 is a linear reciprocating electric push rod. The lifting mechanism 16 drives the up and down movement of the movable cylinder 13 through the connecting rod 15. The up and down movement of the movable cylinder 13 adjusts the position of the conveying assembly 19, and the materials at different positions are tumbling and moving, so as to complete the feeding and mixing of materials at different positions. One end of the lifting mechanism 16 is fixed on the barrel 7. A feeding barrel 10 is movably installed at the top of the movable cylinder 13, and a feeding hopper 11 is fixedly installed at the top of the feeding barrel 10. The feeding barrel 10 is welded and fixed on the support seat 5 through a fixing frame 6. A driving motor 4 is fixedly installed on the fixed seat 3, and a rotating column 17 is installed on the driving motor 4. One end of the rotating column 17 is installed on the inner wall of the barrel 7 through a bearing seat. A connecting hole 25 is formed at the bottom of the barrel 7. Later, the conveying auger 23 and the stirring auger 22 move downward through the connecting hole 25 and contact the arc plate 20.

[0036] In this embodiment, a stirring column 18 is welded on the rotating column 17, and a conveying assembly 19 is movably installed between the stirring columns 18. The conveying assembly 19 includes a stirring auger 22 and a conveying auger 23. The stirring auger 22 and the conveying auger 23 are respectively movably installed inside the movable cylinder 13. A connecting box 8 is fixed at the bottom of the barrel 7, a discharge pipe 9 is movably installed at the bottom of the connecting box 8, and an arc plate 20 is movably installed inside the connecting box 8. A cavity 14 is formed inside the feeding barrel 10, and a fixing hole 31 is formed at the bottom of the cavity 14. The movable cylinder 13 is movably installed inside the fixing hole 31. After one end of the movable cylinder 13 enters the fixing hole 31, the materials inside the feeding barrel 10 are fed into the barrel 7 simultaneously from three points for mixing. The multi-point feeding of materials facilitates the subsequent rapid stirring and mixing.

[0037] In this embodiment, the arc-shaped plate 20 is installed inside the connection box 8 through a support mechanism 21. The support mechanism 21 is a support spring, which pushes the arc-shaped plate 20 upward. After the arc-shaped plate 20 moves upward, it blocks the connection hole 25. When discharging is not required, the arc-shaped plate 20 completes the blocking and sealing of the connection hole 25. One end of the discharge pipe 9 is fixed to the arc-shaped plate 20. A sponge plate 24 is fixed on the arc-shaped plate 20, and the sponge plate 24 is in movable contact with the bottom of the barrel 7. The bottom of the stirring auger 22 is fixed with a stirring plate 26. One end of the conveying auger 23 is movably installed inside the discharge pipe 9. A control box 2 is fixed on the side of the fixed seat 3. A conical seat 27 is fixed inside the movable cylinder 13. The conical seat 27 is fixed inside the movable cylinder 13 through a fixing rod 28. A motor cavity 29 is opened inside the conical seat 27, and a conveying motor 30 is fixedly installed inside the motor cavity 29. The conveying motor 30 is respectively connected to the conveying auger 23 and the stirring auger 22. The materials on the arc-shaped plate 20 are pushed and simultaneously dialed inward by the stirring plate 26, and the materials after moving inward are pushed out of the discharge pipe 9 through the conveying auger 23 for discharging.

[0038] The rubber roller raw material mixing method implemented by using the rubber roller raw material mixing device described in claim 1 includes the following steps:

[0039] Step 1, material preparation: First, an appropriate amount of rubber raw materials need to be prepared, including natural rubber, synthetic rubber, etc. In addition, some auxiliary materials are also required, such as vulcanizing agents, accelerators, antioxidants, etc. The selection of materials will directly affect the quality and service performance of the rubber roller.

[0040] Step 2, proportioning and mixing: According to a specific formula, the rubber raw materials and auxiliary materials are mixed together, and after stirring and kneading, a uniform rubber compound is formed.

[0041] Step 3, filtering the rubber.

[0042] Step 4, forming: Multiple methods can be used during the forming process, such as the lamination forming method, the extrusion winding forming method, etc. In the lamination forming method, the film rolls extruded by the calender are placed on the lamination forming machine, and are wound and laminated layer by layer on the metal roll core; while in the extrusion winding forming method, a hot rubber strip is continuously extruded through an extruder and directly wound on the metal roll core.

[0043] Step 5, vulcanization treatment.

[0044] Step 6, processing and trimming.

[0045] In this embodiment, after the kneading in step three is uniform, a rubber filtering machine is used to remove impurities in the rubber compound to ensure that there are no air bubbles and impurities in the rubber compound, so as to meet the requirements of the rubber roller forming. In step five, the made rubber roller blank is vulcanized, enabling it to undergo a chemical reaction under high temperature and high pressure to increase the crosslinking density of the rubber compound, thereby improving the physical properties and chemical stability of the rubber roller. After the vulcanization treatment in step six is completed, the rubber roller is processed and decorated, including processes such as turning, polishing, and punching, to remove surface defects and uneven parts, so that the rubber roller reaches the required precision and surface quality. Quality inspection is carried out on the made rubber roller, including tests of indicators such as hardness, tensile strength, compression deformation, and thermal stability.

[0046] When the device is in use, first start the lifting mechanism 16 to push the movable cylinder 13 upward. One end of the movable cylinder 13 enters the bottom of the feed hopper 11 through the fixing hole 31, and various materials are respectively poured into the interior of the feed hopper 11. When various materials enter and are mixed in the early stage, the rapid entry of materials is realized through the movable cylinder 13. When feeding, start the conveying motor 30 to drive the conveying auger 23 and the stirring auger 22 to rotate. Through the rotation of the conveying auger 23 and the stirring auger 22, the materials are pushed downward and enter the interior of the barrel 7. Start the driving motor 4 to drive the rotating column 17 and the stirring column 18 to rotate. The stirring column 18 stirs and mixes the materials dropped by the movable cylinder 13. When the feeding is completed, rotate the conveying auger 23 and the stirring auger 22 in the reverse direction. The conveying auger 23 and the stirring auger 22 rotate upward to drive the materials at the bottom to roll. The materials are subjected to multi-point combined stirring through the rotation of the conveying auger 23 and the stirring auger 22. When multi-point feeding of a large amount of the same material is required, move the movable cylinder 13 downward. After the movable cylinder 13 moves downward, the height positions of one end of the conveying auger 23 and the stirring auger 22 are adjusted. Through the change in height, the materials at different positions are pushed upward for stirring. When one end of the movable cylinder 13 stays inside the fixing hole 31, the materials inside the cavity 14 enter the interior of the movable cylinder 13 at three points respectively. Under the rotation of the conveying auger 23 and the stirring auger 22, the materials are pushed into different positions of the barrel 7, and the rapid mixing of the later-stage materials is completed through feeding at different positions. After the stirring is completed, start the lifting mechanism 16 to drive the movable cylinder 13 to descend through the connecting rod 15. When the movable cylinder 13 descends, the conveying auger 23 and the stirring auger 22 contact the arc-shaped plate 20 through the connecting hole 25. The arc-shaped plate 20 moves downward under its push. When the arc-shaped plate 20 moves downward, the support mechanism 21 is extruded. After the arc-shaped plate 20 moves downward, the sponge plate 24 loses extrusion, and after the sponge plate 24 restores its elasticity, the side of the stirring plate 26 is blocked. In the later-stage discharging, the stirring auger 22 rotates to drive the stirring plate 26 to simultaneously push the materials inward. Under the pushing of the materials, it cooperates with the conveying auger 23. The conveying auger 23 rotates inside the discharge pipe 9, and under the rotation, the materials inside the discharge pipe 9 are pushed outward by the conveying auger 23 to avoid blockage.
