Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber mixing machine technology, and in particular to an open-type rubber mixing machine discharge structure. Background Technology
[0002] Rubber mixing mills are key pieces of equipment in the rubber processing industry. They are mainly used to mix, plasticize, and homogenize raw rubber with various compounding agents (such as vulcanizing agents, fillers, plasticizers, etc.) to prepare rubber compounds with certain plasticity and uniformity to meet the requirements of subsequent molding and vulcanization processes.
[0003] A Chinese patent with publication number CN221048800U, entitled "A Feeding Structure for an Open-Type Rubber Mixing Mill," describes an open-type rubber mixing mill. Rollers are installed inside the mill, and a housing is fixedly connected between the inner walls of two supports. Fine circular rollers are symmetrically arranged within the housing, with their shafts fitted into the housing's inner cavity. A servo motor is mounted at the end of each roller, and its lower surface is fixedly connected to the upper surface of the supports. Using an open-type rubber mixing mill with a set of fine circular rollers at the top of the rollers for symmetrical rotational extrusion improves processing efficiency and quality. The feed rate can be more precisely adjusted through parameter control of the servo motors. However, this patent uses two independent motors to drive the two fine circular rollers, which presents a synchronization problem, leading to inconsistent roller speeds and affecting the uniformity of rubber mixing and the stability of equipment operation. Furthermore, the lack of effective restraint on the material-holding groove plate may cause it to detach during operation, further impacting normal equipment operation and production efficiency. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an open-type rubber mixing mill discharge structure.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An open-type rubber mixing mill discharge structure includes a machine body and a base. Support blocks are fixedly connected to both sides of the upper end of the base. Support plates are fixedly connected to the upper ends of the two support blocks. A common discharge frame is fixedly connected to the side of the two support plates that are close to each other. A feeding mechanism is provided in the discharge frame. An insertion slot is opened on one side of the base. A groove frame is inserted into the insertion slot. Fixing mechanisms are provided at both ends of one side of the base to fix the groove frame in the insertion slot.
[0007] As a further improvement of this utility model, the feeding mechanism includes two thin circular rollers disposed in the feeding frame. The same end of the two thin circular rollers passes through the feeding frame and is fixedly connected to a gear. The two gears mesh with each other. The other ends of the two thin circular rollers are rotatably connected to the inner wall of the feeding frame. A motor is fixedly connected to one side of the outer wall of the feeding frame. The output shaft end of the motor passes through the feeding frame and is fixedly connected to a thin circular roller.
[0008] As a further improvement of this utility model, the fixing mechanism includes a rectangular frame fixedly connected to the side wall of the base, a plug block slidably inserted into the rectangular frame, two plug holes being opened on the plug block, a toggle block being fixedly connected to one end of the plug block, a plug post being provided on one side of the rectangular frame, one end of the plug post passing through the rectangular frame and inserted into a plug hole, a pull plate being fixedly connected to the other end of the plug post, a spring sleeved with the plug post being fixedly connected to one side of the pull plate, and the other end of the spring being fixedly connected to the rectangular frame.
[0009] As a further improvement of this utility model, the insertion slot is a T-shaped structure, and the lower end structure of the groove frame matches the insertion slot structure.
[0010] As a further improvement of this utility model, a handle is fixedly connected to one side wall of the groove frame.
[0011] As a further improvement of this utility model, a rolling cylinder is rotatably connected between the two support blocks, and one end of the machine body passes through one of the support blocks and is connected to the rolling cylinder.
[0012] The beneficial effects of this utility model are:
[0013] This open-type rubber mixing mill uses a single motor to drive the fine rollers in the feeding mechanism. A transmission system is formed by meshing gears at the same end of the two rollers, achieving synchronous rotation. Compared to the original patent using two independent motors, this avoids motor synchronization issues and ensures that the two rollers rotate at the same speed. This helps improve the uniformity of rubber compound mixing, allowing the rubber to receive more even processing upon entering the tumbling drum, thereby improving the quality of rubber processing.
[0014] By setting up a fixing mechanism, the groove frame is effectively limited, preventing it from detaching during equipment operation and ensuring the integrity of the equipment structure. Compared with the original patent, which did not effectively limit the groove plate for placing materials, this improves the reliability of normal equipment operation, thereby ensuring production efficiency, reducing production interruptions caused by accidental detachment of the groove frame, and helping to improve the continuity and stability of the entire rubber processing production process.
[0015] This invention effectively improves the uniformity of rubber compound mixing, enhances the reliability of equipment operation and production stability, and improves the quality and efficiency of rubber processing. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Figures 1-5An open-type rubber mixing mill discharge structure includes a machine body 1 and a base 2. Support blocks 3 are fixedly connected to both sides of the upper end of the base 2. A rolling drum 19 is rotatably connected between the two support blocks 3. The rolling drum 19 is the core component for rubber processing. One end of the machine body 1 passes through one of the support blocks 3 and connects to the rolling drum 19, forming an integral structure. Support plates 4 are fixedly connected to the upper ends of both support blocks 3. A common discharge frame 5 is fixedly connected to the side of the two support plates 4 that are close to each other. The discharge frame 5 is used to guide the raw material into the rolling drum 19. The material frame 5 is equipped with a feeding mechanism, which includes two thin circular rollers 14 disposed inside the unloading frame 5. The same end of the two thin circular rollers 14 passes through the unloading frame 5 and is fixedly connected to a gear 13. The two gears 13 mesh with each other to form a transmission system, driving the two thin circular rollers 14 to rotate synchronously. The other ends of the two thin circular rollers 14 are rotatably connected to the inner wall of the unloading frame 5. A motor 6 is fixedly connected to one side of the outer wall of the unloading frame 5. The output shaft end of the motor 6 passes through the unloading frame 5 and is fixedly connected to one of the thin circular rollers 14, driving the entire feeding mechanism to run.
[0024] A slot 7 is provided on one side of the base 2, and a recessed frame 8 is inserted into the slot 7. A handle 12 is fixedly connected to one side wall of the recessed frame 8 for easy removal by the operator. The slot 7 has a T-shaped structure, and the lower end of the recessed frame 8 matches the structure of the slot 7, forming a stable and detachable connection. Both ends of one side of the base 2 are provided with fixing mechanisms to fix the recessed frame 8 in the slot 7. The fixing mechanism includes a rectangular frame 9 fixedly connected to the side wall of the base 2. Insertion blocks 11 are slidably inserted into the rectangular frame 9. When the two insertion blocks 11 extend out of the rectangular frame 9, they will block the recessed frame 8, thereby preventing it from detaching from the slot 7. Two insertion holes 15 are provided on the insertion blocks 11. One end of the plug-in block 11 is fixedly connected to a toggle block 10, which is used to drive the plug-in block 11 to move, thereby causing it to extend out of the blocking groove frame 8, or retract into the rectangular frame 9 without blocking the groove frame 8. A plug-in post 17 is provided on one side of the rectangular frame 9. One end of the plug-in post 17 passes through the rectangular frame 9 and is inserted into a plug-in hole 15 to achieve quick locking and position the plug-in block 11. The other end of the plug-in post 17 is fixedly connected to a pull plate 16, which is used to drive the plug-in post 17 to disengage from the plug-in hole 15. A spring 18 sleeved with the plug-in post 17 is fixedly connected to one side of the pull plate 16. The other end of the spring 18 is fixedly connected to the rectangular frame 9 to provide an automatic reset function.
[0025] When using this utility model, firstly, the motor 6 is turned on, and the motor 6 drives the fine circular roller 14, which is fixedly connected to its output shaft end, to rotate. Since the gears 13 at the same end of the two fine circular rollers 14 mesh with each other, the two fine circular rollers 14 rotate synchronously, and the feeding mechanism starts to work, guiding the raw material into the feeding frame 5 and sending it to the rolling cylinder 19. When it is necessary to operate the groove frame 8, to remove the groove frame 8, pull the pull plate 16 to disengage the plug post 17 from the plug hole 15 on the plug block 11, and then push the plug block 11 into the rectangular frame 9 by the toggle block 10. At this time, the groove frame 8 can be pulled out from the plug groove 7 by holding the handle 12. To install the groove frame 8, insert the groove frame 8 into the plug groove 7, push the plug block 11 out of the rectangular frame 9 by the toggle block 10, and then release the pull plate 16. The spring 18 drives the plug post 17 to insert into the plug hole 15, fixing the plug block 11, thereby fixing the groove frame 8. The entire device can then operate normally and perform rubber processing operations.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
