Abstract

Technical Field
[0001] This utility model relates to the field of rubber release agent preparation technology, specifically a centralized preparation device for rubber release agents. Background Technology
[0002] In the tire industry, after the mixing process, the rubber sheets need to be treated with a release agent. This step prevents the rubber sheets from sticking together, deforming, or breaking due to their high viscosity, ensuring smooth subsequent processing. At the same time, it reduces the surface friction coefficient of the rubber sheets, improves processing performance and surface smoothness, and reduces defects. It also protects the surface of the rubber compound from oxidation, moisture absorption, or contamination, and assists in demolding during molding and vulcanization, improving production efficiency and product quality, adapting to the needs of automated production, and the rational selection of release agents can balance environmental safety and economic benefits.
[0003] However, the dispersed release agent preparation mode currently used by most factories has multiple drawbacks: the release agent is prone to sedimentation when stored inside the mixing tank for a long time, it is inconvenient to effectively stir the release agent, and it cannot effectively inhibit the sedimentation phenomenon.
[0004] Therefore, we propose a centralized preparation device for rubber release agents to improve upon the above-mentioned problems. Utility Model Content

[0013] As a further technical solution of this utility model, the top of the left and right sides of the mixing tank is fixedly connected with a support block, and the support block and the cover plate are respectively provided with a fixing groove on the left and right sides. The fixing groove is provided with a fixing bolt, and the cover plate is fixed to the top of the mixing tank by the fixing bolt and the fixing groove.
[0014] Compared with the prior art, the beneficial effects of this utility model are: the centralized configuration device for rubber release agents not only effectively suppresses the deposition of release agents and facilitates the uniformity of release agent ratio, but also enables the release agent to be added by opening the feeding cover;
[0015] (1) By setting up a stirring rod, stirring blade, variable frequency speed control motor, rotating shaft, drive gear, driven gear and splicing sleeve, the variable frequency speed control motor is started. The variable frequency speed control motor drives the drive gear to rotate through the rotating shaft. The drive gear drives the mounting shaft and liquid level sensor to rotate inside the mixing tank through the driven gear and mounting sleeve. Thus, the release agent inside the mixing tank can be stirred by the stirring rod and stirring blade, preventing the release agent from depositing inside the mixing tank and affecting subsequent use, and reducing additional expenses caused by quality problems;

When the material level inside the mixing tank reaches the low material level, the solenoid valve on the discharge pipe is closed, and the alarm sounds at the same time to remind the operator to add the release agent. After pressing the confirmation button, the alarm is extinguished, the solenoid valve on the water inlet pipe is opened, and water enters the interior of the mixing tank through the water inlet pipe. The release agent enters the interior of the mixing tank through the discharge box. When the water level reaches the high material level, the solenoid valve on the water inlet pipe is automatically closed to stop water injection, and the solenoid valve on the discharge pipe is automatically opened, so that it can be added to the interior of the sub-tank through the branch pipe at the bottom of the water outlet pipe. Side blow ports are arranged at certain intervals on the top of the branch pipe. The compressed air pulse frequency is controlled by PLC linkage. Combined with the hydrophobic coating treatment of the pipe wall, the amount of deposits attached to the pipe is reduced. The liquid level sensor is used to monitor the liquid level of the mixing tank in real time. The linkage solenoid valve and electromagnetic flow meter form an adjustment loop to achieve precise control of the release agent dilution ratio.
[0017] (3) By setting up a feeding port, feeding cover, fixing bolts, fixing groove and support block, after the cover is placed on the top of the mixing tank, the fixing bolts are screwed into the inside of the fixing groove to limit and fix the cover, so as to prevent the cover from accidentally shifting at the top of the mixing tank and affecting subsequent processing.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-4 This utility model provides an embodiment of a centralized preparation device for rubber release agents, comprising a mixing tank 1 and a support 21. The mixing tank 1 is mounted on the top of the support 21, and a staircase 24 is mounted on the front left side of the support 21. A cover plate 28 is mounted on the top of the mixing tank 1, and a variable frequency speed control motor 12 is mounted on the right side of the top of the cover plate 28. A feeding box 8 is mounted on the right side of the top of the mixing tank 1. A rotating shaft 13 is fixedly connected to the output end of the variable frequency speed control motor 12. A drive gear 14 is mounted on the outside of the rotating shaft 13. An installation sleeve 16 is mounted at the middle position of the top of the cover plate 28. A connecting shaft 26 is movably connected inside the installation sleeve 16. A driven gear 15 is fixedly connected to the top of the connecting shaft 26. An installation shaft 25 is mounted at the bottom of the connecting shaft 26. A splicing sleeve 17 is provided at the connection between the connecting shaft 26 and the installation shaft 25. A fixing sleeve 27 is mounted on the outside of the installation shaft 25. A stirring blade 3 is fixedly connected to the left and right sides of the fixing sleeve 27.
[0025] The mounting shaft 25 is mounted on the bottom end of the connecting shaft 26 via the splicing sleeve 17. The stirring blade 3 is set inside the stirring tank 1. The driving gear 14 and the driven gear 15 are meshed. The top end of the connecting shaft 26 rotates inside the mounting sleeve 16 via the bushing.
[0026] Specifically, such as Figure 1 and Figure 3As shown, the variable frequency speed control motor 12 is started. The variable frequency speed control motor 12 drives the drive gear 14 to rotate through the rotating shaft 13. The drive gear 14 drives the mounting shaft 25 and the liquid level sensor 4 to rotate inside the mixing tank 1 through the driven gear 15 and the mounting sleeve 16. This allows the stirring rod 2 and the stirring blade 3 to stir the release agent inside the mixing tank 1, preventing the release agent from depositing inside the mixing tank 1 and affecting subsequent use, thus reducing additional expenses caused by quality problems.
[0027] Liquid level sensors 4 are installed at the upper and lower ends of the left side of the mixing tank 1. A discharge pipe 20 is fixedly connected to the middle position of the bottom of the mixing tank 1. A water outlet pipe 19 is installed at the bottom of the right side of the mixing tank 1. A water inlet pipe 5 is fixedly connected to the left side of the top of the cover plate 28. A connecting pipe 18 is provided at the top of the water inlet pipe 5 and the water outlet pipe 19. A solenoid valve 6 and an electromagnetic flow meter 7 are installed on the water inlet pipe 5, the water outlet pipe 19, the connecting pipe 18 and the discharge pipe 20 respectively. The discharge pipe 20 is fixedly connected between the water outlet pipe 19 and the bottom of the mixing tank 1. A branch pipe is fixedly connected to the bottom of the water outlet pipe 19. A multi-component tank is provided at the bottom of the branch pipe. A blow nozzle is machined at the top of the branch pipe. A support plate 10 is fixedly connected to the front end of the feeding box 8. An alarm 9 is installed at the top of the support plate 10.
[0028] Specifically, such as Figure 1 and Figure 2 As shown, the liquid level sensor 4 inside the mixing tank 1 can detect the liquid volume inside the mixing tank 1. When the material level inside the mixing tank 1 reaches the low level, the solenoid valve 6 on the discharge pipe 20 is closed, and the alarm 9 sounds at the same time, reminding the operator to add the release agent. After pressing the confirmation button, the alarm is extinguished, the solenoid valve 6 on the water inlet pipe 5 is opened, and water enters the interior of the mixing tank 1 through the water inlet pipe 5. The release agent enters the interior of the mixing tank 1 through the discharge box 8. When the water level reaches the high level, the solenoid valve 6 on the water inlet pipe 5 is automatically closed to stop water injection, and the solenoid valve 6 on the discharge pipe 20 is automatically opened, so that water can be added to the interior of the distribution tank through the branch pipe at the bottom of the water outlet pipe 19. Side blow ports are arranged at certain intervals on the top of the branch pipe. The compressed air pulse frequency is controlled by the PLC linkage, and the hydrophobic coating treatment of the pipe wall reduces the amount of deposits adhering to the pipe. The liquid level sensor 4 monitors the liquid level of the mixing tank in real time, and the linkage solenoid valve 6 and electromagnetic flow meter 7 form an adjustment loop to achieve precise control of the release agent dilution ratio.
[0029] A feeding port 22 is fixedly connected to the rear end of the top of the feeding box 8. A feeding cover 23 is provided at the top of the feeding port 22. A feeding pipe 11 is fixedly connected to the bottom of the feeding box 8. The feeding pipe 11 is installed at the rear end of the right side of the top of the cover plate 28. Support blocks 31 are fixedly connected to the top of the left and right sides of the mixing tank 1. Fixing grooves 30 are respectively opened on the left and right sides inside the support blocks 31 and the cover plate 28. Fixing bolts 29 are provided inside the fixing grooves 30. The cover plate 28 is fixed to the top of the mixing tank 1 by fixing bolts 29 and fixing grooves 30.
[0030] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, after the cover plate 28 is placed on the top of the mixing tank 1, the fixing bolt 29 is screwed into the inside of the fixing groove 30 to limit and fix the cover plate 28, preventing the cover plate 28 from accidentally shifting off the top of the mixing tank 1 and affecting subsequent processing. When it is necessary to adjust the release agent inside the feed box 8, the feed cover 23 is removed from the top of the feed port 22 by the handle at the top of the feed cover 23. After removing it, it is convenient to add the release agent into the inside of the feed box 8 through the feed port 22.
[0031] Working principle: When using this utility model, after the cover plate 28 is placed on the top of the mixing tank 1, the fixing bolts 29 are screwed into the fixing groove 30 to limit and fix the cover plate 28, preventing the cover plate 28 from accidentally shifting off the top of the mixing tank 1 and affecting subsequent processing. The liquid level sensor 4 inside the mixing tank 1 can detect the liquid volume inside the mixing tank 1. When the material level inside the mixing tank 1 reaches the low level, the solenoid valve 6 on the discharge pipe 20 is closed, and the alarm 9 sounds at the same time, reminding the operator to add a release agent. After pressing the confirmation button, the alarm is extinguished, the solenoid valve 6 on the water inlet pipe 5 is opened, and water enters the mixing tank through the water inlet pipe 5. When adjusting the release agent inside the feed hopper 8, the feed cover 23 is removed from the top of the feed port 22 using the handle at the top of the feed cover 23. After removal, the release agent is easily added to the feed hopper 8 through the feed port 22. The release agent then enters the mixing tank 1 through the feed hopper 8. When the water level reaches the high level, the solenoid valve 6 on the inlet pipe 5 automatically closes, stopping water injection, and the solenoid valve 6 on the outlet pipe 20 automatically opens, allowing water to be added to the sub-tank through the branch pipe at the bottom of the outlet pipe 19. Side blow ports are arranged at certain intervals at the top of the branch pipes, controlled by a PLC. The linkage control of compressed air pulse frequency, combined with the hydrophobic coating treatment of the pipe wall, reduces the amount of deposits adhering to the pipe. The liquid level sensor 4 monitors the liquid level of the mixing tank in real time. The linkage solenoid valve 6 and electromagnetic flow meter 7 form an adjustment loop to achieve precise control of the dilution ratio of the release agent. When the material level in the sub-tank reaches the low level, the solenoid valve 6 on the discharge pipe 20 is automatically opened to add material. After reaching the high level, the solenoid valve 6 on the discharge pipe 20 is automatically closed, and the variable frequency speed control motor 12 is started. The variable frequency speed control motor 12 drives the drive gear 14 to rotate through the rotating shaft 13. The drive gear 14 drives the mounting shaft 25 and the liquid level sensor 4 to rotate inside the mixing tank 1 through the driven gear 15 and the mounting sleeve 16. Thus, the release agent inside the mixing tank 1 can be stirred by the stirring rod 2 and the stirring blade 3, preventing the release agent from depositing inside the mixing tank 1 and affecting subsequent use, and reducing additional expenses caused by quality problems.
[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
