Description

Technical Field

[0001] This utility model relates to the field of feeding machine technology, and more specifically, to a rubber feeding machine with a telescopic structure. Background Technology

[0002] In the conveying process of plastic powder granules, rubber feeders with telescopic structures play a crucial role. Due to the characteristics of plastic powder granules, such as particle size distribution and shape, the design requirements for feeders are relatively high. Rubber feeders with telescopic structures can adapt to different particle sizes and shapes, ensuring uniform and continuous conveying of powder granules. Simultaneously, the elasticity of the rubber material can reduce wear on the feeder from powder granules to a certain extent, extending the service life of the equipment. In existing technologies, directly conveying plastic powder granules onto a conveyor belt presents several problems. Plastic powder granules may scatter during conveying due to vibration or uneven speed, leading to material waste and environmental pollution. Furthermore, the hardness or sharpness of the granules can easily wear down the conveyor belt, shortening its service life and affecting conveying efficiency. Uneven particle distribution can also cause belt misalignment, affecting the normal operation of the conveyor. In addition, plastic powder is prone to generating static electricity during conveying, which, if not handled properly, may cause safety hazards such as fire or explosion. Moreover, factors such as humidity, particle size differences, or conveying speed can also cause blockage problems, further affecting conveying efficiency. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0029] like Figures 1 to 8 As shown, this utility model provides a rubber feeder with a telescopic structure, including a support platform 1 and a support frame 2. A mixing tank 3 is movably installed inside the support platform 1, and both ends of the mixing tank 3 pass through the inside of the support platform 1. A discharge pipe 20 is fixedly installed at the bottom of the mixing tank 3, and a one-way valve 21 is fixedly installed inside the discharge pipe 20.

[0030] A rotating shaft 19 is movably installed inside the mixing tank 3, with one end of the rotating shaft 19 penetrating through the interior of the mixing tank 3. A first gear 22 is fixedly installed at one end of the rotating shaft 19. A housing 5 is fixedly installed on the top of the mixing tank 3. A first motor 6 is fixedly installed on the top of the housing 5. A second gear 23 is fixedly installed at the output end of the first motor 6, and the second gear 23 meshes with the first gear 22. A stirring rod 18 is fixedly installed on the outer surface of the rotating shaft 19. A feed pipe 4 is fixedly installed on the top of the mixing tank 3.

[0031] The worker pours the plastic powder particles to be mixed into the mixing tank 3 through the feed pipe 4, and then turns on the first motor 6 at the top of the tank 5. The first motor 6 drives the second gear 23 to rotate. The second gear 23 meshes with the first gear 22, and the second gear 23 drives the first gear 22 to rotate. The first gear 22 drives the rotating shaft 19 to rotate inside the support platform 1. The rotating shaft 19 drives the stirring rod 18 to rotate, and the stirring rod 18 mixes the plastic powder particles evenly. After the plastic powder particles are evenly mixed, the one-way valve 21 is opened inside the discharge pipe 20, so that the evenly mixed plastic powder particles slowly fall into the next step through the discharge pipe 20, thereby completing the even mixing of the plastic powder particles.

[0032] The plastic powder particles to be mixed are poured into the mixing tank 3 through the feed pipe 4. Then, the first motor 6 is turned on at the top of the housing 5. The first motor 6 drives the second gear 23 to rotate, which in turn drives the first gear 22 to rotate. The first gear 22 drives the rotating shaft 19 to rotate inside the support platform 1. The rotating shaft 19 drives the stirring rod 18 to rotate, and the stirring rod 18 mixes the plastic powder particles evenly. Compared with traditional feeding machines, this feeding machine, through the cooperation between the stirring rod 18 and the rotating shaft 19, facilitates the even mixing of plastic powder particles inside the mixing tank 3. The application of the stirring rod 18 inside the mixing tank 3... The mixing quality is significantly improved, ensuring that the plastic powder particles are fully stirred and mixed, achieving a highly uniform effect. This plays a crucial role in ensuring the production quality of rubber products. At the same time, uniform mixing also shortens the mixing time, thereby optimizing production efficiency and enabling the rubber feeder to complete its tasks more quickly. In addition, by optimizing the stirring method and speed of the stirring rod, not only is the mixing quality guaranteed, but energy consumption is also effectively reduced, achieving the goal of energy conservation and emission reduction. It is worth mentioning that the rubber feeder with a telescopic structure can be adapted to rubber mixing machines of different heights, and the uniform mixing function of the rotating shaft-19 further enhances the adaptability and flexibility of the equipment.

[0033] The support frame 2 has a telescopic rod 25 movably installed inside, a support block 32 is fixedly installed on the top of the telescopic rod 25, and a conveying mechanism is fixedly installed on the top of the support block 32.

[0034] A housing 26 is fixedly installed on the outside of the support frame 2. A positioning hole 24 is opened inside the telescopic rod 25, and a positioning block 33 is movably installed inside the positioning hole 24. A pull rod 31 is fixedly installed at one end of the positioning block 33, and one end of the pull rod 31 passes through the inside of the housing 26. A spring 10 is fixed between the housing 26 and the positioning block 33.

[0035] The operator needs to adjust the conveying mechanism according to the height of the rubber mixing machine. By holding the pull rod 31, the operator moves the positioning block 33 inside the positioning hole 24. The positioning block 33 compresses the spring 10, causing it to pass through the support frame 2 and enter the housing 26. Now, the positioning block 33 releases its restriction on the telescopic rod 25. By holding the telescopic rod 25, the operator moves it up and down on the support frame 2. The telescopic rod 25 drives the support block 32 synchronously, which in turn drives the conveying mechanism to move up and down. When the conveying mechanism reaches the appropriate height from the rubber mixing machine, the operator releases the pull rod 31. The spring 10 compresses the positioning block 33, causing it to pass through the support frame 2 and enter the housing 26, thus limiting and fixing the telescopic rod 25 inside the support frame 2. This allows for the adjustment of the conveying mechanism's angle.

[0036] To adjust the conveying mechanism to a height that matches the rubber mixer, the operator must first hold the component pull rod 31 and use it to pull the positioning block 33 to slide inside the positioning hole 24. As the positioning block 33 moves, it compresses the spring 10, causing the positioning block 33 to pass through the interior of the support frame 2 and enter the housing 26. At this point, the positioning block 33 no longer restricts the telescopic rod 25. The operator can hold the telescopic rod 25 and move it freely up and down on the support frame 2, driving the connected support block 32 and the conveying mechanism to rise and fall synchronously. When the appropriate height is reached, the pull rod 31 is released, and the spring 10 squeezes the positioning block 33 again, allowing it to pass through the support frame 2 and enter the housing 26, thereby limiting and fixing the telescopic rod 25 and ensuring that the conveying mechanism is stable at the required height. Compared with traditional feeding, this feeding machine, through the cooperation between the positioning block 33, the spring 10 and the positioning hole 24, facilitates the angle adjustment of the conveying mechanism, which can significantly optimize the material conveying process, reduce unnecessary conveying distance, and thus greatly improve conveying efficiency. Its adjustable angle design gives the rubber feeding machine height adaptability and flexibility, making it easy to adapt to rubber mixing machines of different heights and tilt angles. Within a limited production space, the rubber feeder achieves efficient material conveying by reasonably adjusting the angle of the conveying mechanism, effectively saving space. In addition, reasonable adjustment of the conveying angle can reduce the wear of the material on the conveying mechanism, extend the service life of the equipment, and the angle adjustment operation is simple and does not require complicated technical support, which helps to simplify the daily maintenance and upkeep of the equipment.

[0037] The conveying mechanism is fixedly installed on the top of the support block 32. The conveying mechanism includes a fixed bracket 17 fixedly installed on the top of the support block 32. A second rotating shaft 29 is movably installed inside the fixed bracket 17, and both ends of the second rotating shaft 29 pass through the interior of the fixed bracket 17. A third rotating shaft 30 is movably installed inside the fixed bracket 17, and both ends of the third rotating shaft 30 pass through the interior of the fixed bracket 17. A second motor 27 is fixedly installed on the front of the fixed bracket 17, and the output end of the second motor 27 is fixedly connected to one end of the third rotating shaft 30. A conveyor belt 28 is internally connected to the third rotating shaft 30 and the second rotating shaft 29.

[0038] When the operator opens the one-way valve 21 inside the discharge pipe 20, the uniformly mixed plastic powder particles are allowed to slowly fall through the discharge pipe 20 onto the top of the conveyor belt 28. Then, the second motor 27 is turned on, which drives the rotating shaft 30 to rotate inside the fixed bracket 17. The rotating shaft 30 then drives the conveyor belt 28 and the rotating shaft 29 to rotate within the fixed bracket 17. The uniformly mixed plastic powder particles are then moved through the conveyor belt 28 into the rubber mixing machine, thus completing the conveying of the plastic powder particles and improving the conveying efficiency of the uniformly mixed plastic powder particles.

[0039] Among them, a support plate 11 is fixedly installed at the bottom of the support platform 1, and a connecting plate 12 is fixedly installed between the two support plates 11.

[0040] The cooperation between the support plate 11 and the connecting plate 12 facilitates the support platform 1, and the support platform 1 provides stable support for the mixing tank 3, ensuring the stability of the plastic powder particles in the mixing tank 3 during the mixing process.

[0041] A connecting plate 12 is fixedly installed at the angle between the support plate 11 and the reinforcing rib 13, and the connecting plate 12 is triangular in shape.

[0042] Since the connecting plate 12 is triangular in shape at the angle between the support plate 11 and the reinforcing rib 13, the triangle has the characteristic of stability, which avoids the support plate 11 and the reinforcing rib 13 from shaking during use and improves the stability of the support plate 11 and the connecting plate 12 during use.

[0043] Among them, a motor protective cover 7 is fixedly installed on the outer surface of the first motor 6, and a column 8 is fixedly installed between the motor protective cover 7 and the housing 5.

[0044] The cooperation between the motor protective cover 7 and the column 8 facilitates stable support for the first motor 6, thus preventing the first motor 6 from shaking during use, ensuring the stability of the first motor 6 during use, and improving the efficiency of the first motor 6.

[0045] The motor protective cover 7 has heat dissipation holes 9 inside, and the heat dissipation holes 9 are arranged in a circular array.

[0046] Since the heat dissipation holes 9 are arranged in a circular array inside the motor protective cover 7, it is convenient to dissipate heat from the first motor 6, ensuring that the temperature of the first motor 6 is stable during use and extending the service life of the first motor 6.

[0047] The support platform 1 has a fixing groove 14 inside, a fixing block 15 is movably installed inside the fixing groove 14, and a toolbox 16 is fixedly installed on the back of the fixing block 15.

[0048] By holding the toolbox 16, the fixing block 15 is slowly placed into the fixing slot 14. The fixing slot 14 limits and fixes the fixing block 15. By adding the toolbox 16, it is convenient for the staff to take out and place maintenance tools inside the toolbox 16.

[0049] The inner diameter of the fixing groove 14 is equal to the outer diameter of the fixing block 15, and the inner surface of the fixing groove 14 is smooth.

[0050] Since the inner diameter of the fixing groove 14 is equal to the outer diameter of the fixing block 15, and the inner surface of the fixing groove 14 is smooth, it is easy to hold the toolbox 16 and slowly put the fixing block 15 into the fixing groove 14, thereby improving the installation efficiency of the toolbox 16.

[0051] The stirring rods 18 are arranged in a circular array on the outer surface of the rotating shaft 19, and the stirring rods 18 are made of stainless steel.

[0052] Because the stirring rod 18 is made of stainless steel and is arranged in a circular array, the stainless steel material provides good corrosion resistance, making it suitable for long-term use.

[0053] Working principle and usage process of this utility model:

[0054] The worker pours the plastic powder particles to be mixed into the mixing tank 3 through the feed pipe 4, and then turns on the first motor 6 at the top of the tank 5. The first motor 6 drives the second gear 23 to rotate. The second gear 23 meshes with the first gear 22, and the second gear 23 drives the first gear 22 to rotate. The first gear 22 drives the rotating shaft 19 to rotate inside the support platform 1. The rotating shaft 19 drives the stirring rod 18 to rotate, and the stirring rod 18 mixes the plastic powder particles evenly. After the plastic powder particles are evenly mixed, the one-way valve 21 is opened inside the discharge pipe 20, so that the evenly mixed plastic powder particles slowly fall into the next step through the discharge pipe 20, thereby completing the even mixing of the plastic powder particles.

[0055] The operator needs to adjust the conveying mechanism according to the height of the rubber mixing machine. By holding the pull rod 31, the operator moves the positioning block 33 inside the positioning hole 24. The positioning block 33 compresses the spring 10, causing it to pass through the support frame 2 and enter the housing 26. Now, the positioning block 33 releases its restriction on the telescopic rod 25. By holding the telescopic rod 25, the operator moves it up and down on the support frame 2. The telescopic rod 25 drives the support block 32 synchronously, which in turn drives the conveying mechanism to move up and down. When the conveying mechanism reaches the appropriate height from the rubber mixing machine, the operator releases the pull rod 31. The spring 10 compresses the positioning block 33, causing it to pass through the support frame 2 and enter the housing 26, thus limiting and fixing the telescopic rod 25 inside the support frame 2. This allows for the adjustment of the conveying mechanism's angle.
