Description

Technical Field

[0001] The utility model relates to the technical field of rubber mixing machine distance adjustment, in particular to a novel distance adjustment device for a rubber mixing machine. Background Art

[0002] Rubber mixing machine is an important casting machine, which is mainly used in rubber heat refining, sheeting, rubber breaking, plastic refining and mixing processes. According to the structural characteristics, it can be divided into two categories: open type and closed type. In the rubber refining operation, the rubber mixing machine uses mechanical action and thermal energy to fully mix rubber with various auxiliary raw materials (such as fillers, plasticizers, vulcanizers, etc.) to achieve ideal plasticity and viscosity to meet the needs of subsequent processing and molding. At the same time, the rubber mixing machine has a compact structure and is easy to close, which helps to collect waste gas efficiently and show excellent environmental protection performance.

[0003] However, the current rubber mixer has some obvious shortcomings in terms of pitch adjustment. First, the use of hydraulic pitch adjustment leads to reduced accuracy. Since the hydraulic system is affected by factors such as oil temperature changes, oil leakage and impurities during long-term operation, its performance may fluctuate, thus affecting the accuracy of pitch adjustment. This fluctuation may lead to unstable pitch adjustment operation of the rubber mixer, which has a negative impact on product quality and production efficiency.

[0004] Secondly, key components in the hydraulic system, such as pumps, valves, and cylinders, will wear and age over time. These worn and aged components will further reduce the performance of the hydraulic system, which in turn affects the accuracy of the distance adjustment. For example, a decrease in the sealing performance of the cylinder may lead to leakage problems, which will seriously affect the accuracy of the distance adjustment. Utility Model Content

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 - Figure 4 As shown, a novel pitch adjustment device of a rubber mixer has an innovative design, which makes the rubber mixing process more accurate and efficient. The device is mainly composed of core components such as a base 1, a rubber mixer body 2, a rubber roller 3 and a side frame 4. Among them, the rubber mixer body 2 and the side frame 4 are both firmly mounted on the base 1 to ensure that the entire device is stable and reliable.

[0027] Two rubber rollers 3 are cleverly installed between the side frames 4, which are key components for realizing the rubber mixing function. In order to achieve accurate adjustment of the position of the rubber rollers 3, a connecting plate 5 and a fixing plate 8 are specially arranged at the opening of the side frame 4. The two plates are respectively located on the outside and inside of the opening of the side frame 4, forming an ingenious support and fixing structure.

[0028] The outer end of the connecting plate 5 is also provided with a mounting plate 6, and the three form a whole. On the end faces of the connecting plate 5, the mounting plate 6 and the fixing plate 8, waist holes 7 are provided, which not only facilitate the connection between the components, but also make the structure of the whole device more compact.

[0029] An adjusting plate 9 is provided at the inner end of the fixing plate 8, and its position can be adjusted as required. A docking rod 10 is provided at the inner end of the adjusting plate 9, and this rod is cleverly inserted into the waist hole 7 and mounted on the connecting plate 5 and the mounting plate 6. In this way, by adjusting the position of the docking rod 10, the rubber roller 3 can be accurately adjusted.

[0030] The rod body of the docking rod 10 is provided with a joint 11, which is connected to the pitch-adjusting screw 12. The joint 11 and the pitch-adjusting screw 12 are connected by a T-key and a T-slot, which is both firm and easy to disassemble. The pitch-adjusting screw 12 passes through the side frame 4 and is connected to a handle 13. By turning the handle 13, the position of the pitch-adjusting screw 12 can be easily adjusted.

[0031] The adjustment plate 9 is also connected to the rubber roller 3 through a connecting rod 14. When the pitch adjustment screw 12 is rotated, it pushes the docking rod 10 to move along the waist hole 7, and then drives the rubber roller 3 to adjust its position through the connecting rod 14. This design makes the pitch adjustment process smoother and more accurate.

[0032] The side frames 4 are parallel to the base 1 and are firmly fixed to the base 1 by bolts. The rotating shaft of the side frame 4 is connected to the driving device of the rubber mixer to ensure the stable operation of the entire device. The connecting plate 5 and the fixing plate 8 are fixed to the side frame 4 by welding, which enhances the stability and reliability of the entire structure.

[0033] The end surface of the connecting plate 5 is provided with threaded holes in an array, which facilitates bolt connection with the mounting plate 6. After the mounting plate 6 is tightly fitted with the connecting plate 5, it is fixed together by bolts. At the same time, the waist holes 7 on the connecting plate 5 and the mounting plate 6 need to be aligned to ensure that the docking rod 10 can be smoothly inserted and play a supporting role.

[0034] The contact end of the fixed plate 8 and the adjusting plate 9 is designed to be smooth to reduce friction and wear. The adjusting plate 9 can be adjusted along the waist hole 7 on the fixed plate 8, thereby achieving accurate control of the rubber roller 3.

[0035] The rod head of the docking rod 10 is provided with a bearing, and the bearing is embedded in the waist hole 7 opened in the mounting plate 6. This design enables the docking rod 10 to move smoothly in the waist hole 7 while maintaining a stable supporting effect. The docking rod 10 and the joint 11 are arranged perpendicular to each other, and this layout makes the entire structure more compact and reasonable.

[0036] The upper end of the joint 11 is provided with a T-slot for connecting with the T-key at the lower end of the pitch-adjusting screw 12. The connection between the T-slot and the T-key is designed to be smooth to reduce friction resistance and ensure smooth operation of the connection. The pitch-adjusting screw 12 and the side frame 4 are connected by a threaded connection, which is both firm and easy to adjust.

[0037] The connecting rod 14 is fixedly connected to the pitch adjusting screw rod 12 by bolts, and the two are arranged perpendicular to each other. This arrangement enables the connecting rod 14 to stably transmit the thrust or pulling force of the pitch adjusting screw rod 12 to the rubber roller 3, thereby realizing a precise pitch adjusting function.

[0038] Distance adjustment process: Confirm that the rubber mixer is in shutdown state to ensure safe operation. The operator needs to stand in a suitable position of the equipment for easy observation and operation.

[0039] Next, the pitch adjustment process is started by turning the handle 13 on the pitch adjustment screw 12. Since the pitch adjustment screw 12 is threadedly connected to the side frame 4, turning the handle 13 will cause the pitch adjustment screw 12 to move on the side frame 4.

[0040] As the pitch adjusting screw rod 12 moves, the joint 11 connected thereto will also move. Since the joint 11 is connected to the docking rod 10, and the rod head of the docking rod 10 is provided with a bearing and embedded in the waist hole 7 provided in the mounting plate 6, the docking rod 10 will move along the waist hole 7.

[0041] The movement of the docking rod 10 is transmitted to the rubber roller 3 through the connecting rod 14. Since the connecting rod 14 is fixedly connected to the pitch-adjusting screw 12 by bolts and the two are arranged perpendicular to each other, the connecting rod 14 can stably transmit the thrust or pull of the pitch-adjusting screw 12 to the rubber roller 3.

[0042] As the connecting rod 14 is pushed or pulled, the rubber roller 3 will be adjusted between the side frames 4. Due to the ingenious design and support between the connecting plate 5, the mounting plate 6 and the fixed plate 8, the movement of the rubber roller 3 will remain stable and accurate.

[0043] When the desired distance adjustment position is reached, stop rotating the handle 13 and check whether the position of the rubber roller 3 is accurate. If fine adjustment is required, the handle 13 can be rotated again for fine adjustment.

[0044] Finally, after confirming that the position of the rubber roller 3 is adjusted correctly, the rubber mixer is restarted to perform the rubber mixing operation. During the entire distance adjustment process, the operator needs to stay focused to ensure accurate and safe operation, and the distance adjustment process of the rubber roller 3 of the rubber mixer is completed. The design of this distance adjustment device makes the rubber mixing process more accurate and efficient, and improves production efficiency and product quality.

[0045] The utility model significantly improves the rubber mixing accuracy and operation convenience by adding a pitch-adjusting structure. The pitch-adjusting structure achieves the accuracy of the rubber roller position adjustment by accurately matching the docking rod, waist hole, pitch-adjusting screw and side frame, as well as the precise control of the rubber roller by the connecting rod, ensuring the uniform distribution and full mixing of the rubber material, thereby improving the quality of rubber mixing. At the same time, by turning the handle on the pitch-adjusting screw, the operator can easily adjust the position of the rubber roller, reduce the difficulty of operation, and improve work efficiency. In addition, the structure enhances the stability and reliability of the rubber mixer, reduces failures and downtime, and improves the overall operating efficiency. Finally, its modular design allows different models of rubber mixers to flexibly replace the pitch-adjusting device to meet personalized needs.

[0046] The above are the preferred embodiments of the utility model and the technical principles used therein. For those skilled in the art, without departing from the spirit and scope of the utility model, any obvious changes such as equivalent transformation, simple replacement, etc. based on the technical solution of the utility model shall fall within the protection scope of the utility model.
