Description

Technical Field

[0001] The invention relates to the technical field of rubber processing equipment, and in particular to a buffer feeding device of recycled rubber molding equipment. Background Art

[0002] In the modern industrial field, screw pumps, with their unique working principles and excellent performance advantages, occupy an indispensable and important position in many industrial application scenarios. They are widely used in petrochemical, sewage treatment, food processing and other industries, and are one of the key technologies currently developed in my country. The quality and performance of the stator rubber bushing, a key component of the screw pump, directly determine the overall working efficiency and service life of the screw pump. The molding technology of the rubber bushing is the key link to ensure its quality and performance. From the selection of rubber materials, the design of the formula, to each parameter setting of the molding process, it has a vital impact on the performance of the final product. It can even be said that the level of rubber bushing molding technology can largely represent the advanced level of screw pump technology.

[0003] Existing rubber bushings are usually made of recycled rubber. The raw materials of recycled rubber come from a wide range of sources, including various types of waste rubber products such as waste tires and rubber seals. After these waste rubber products are crushed, the resulting recycled rubber raw materials show obvious characteristics: the particle sizes are uneven and the shapes are also very irregular. In addition, some recycled rubbers contain more sticky components, and during the feeding process, this stickiness will cause the rubber particles to stick to each other. As a result, during the feeding process, larger particles are very likely to block the feeding channel, thereby hindering the normal feeding order and affecting the continuity and stability of production. Summary of the invention

[0004] The main purpose of the present invention is to provide a buffer feeding device for recycled rubber molding equipment to overcome the problems existing in the prior art.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] Through the above technical solution, the feeding component can break up the sticky materials and then use the vibrating filter to screen them, effectively avoiding large particles from blocking the feeding channel, ensuring the smoothness of the feeding, and thus maintaining the continuity and stability of production.

[0014] Through the above technical solution, the guidance of the discharge cone and the shock absorption of the buffer component allow the material to enter the dispersing area in the feed bin in a more orderly manner, which is conducive to the stability of subsequent feeding processes such as dispersing and screening, thereby improving the feeding quality and production efficiency of the entire recycled rubber molding equipment.

[0030] The technical solution of the present invention is further described below through the accompanying drawings and embodiments.

[0031] Combination Figures 1 to 6 , this embodiment provides a buffer feeding device of a recycled rubber molding device, including an extruder 1, a feeding bin 2 is provided at one end of the extruder 1, and a feeding assembly is provided inside the feeding bin 2;

[0032] The feed assembly includes a scattering component and a screening component. The scattering component includes a connecting rod 13. The top of the connecting rod 13 is fixedly connected with a plurality of scattering rods 8. The plurality of scattering rods 8 are located inside the feed bin 2.

[0033] The screening component includes a filter screen 7. Connecting plates 10 are provided at both ends of the inner side of the feed bin 2. Both ends of the filter screen 7 are located on the inner side of the connecting plate 10. An elastic member 15 is fixedly connected to the bottom of the filter screen 7. The two elastic members 15 are respectively fixedly connected to the corresponding connecting plates 10. A vibration motor 18 is provided at the bottom of the filter screen 7.

[0034] After the material enters the feed bin 2, the breaking rod 8 located inside the feed bin 2 breaks up the material under the drive of the connecting rod 13. Since there are multiple breaking rods 8, they can stir and impact the material, especially for the recycled rubber particles that are bonded together due to sticky components. Through the mechanical action of the breaking rods 8, large agglomerates are broken up into smaller particles, so as to prevent the material from entering the subsequent process in large blocks.

[0035] The broken materials will fall on the filter screen 7. The filter screen 7 plays a screening role, and its mesh size is designed to allow small particles that meet the requirements to pass through, while blocking oversized particles. When the material falls on the filter screen 7, the vibration motor 18 starts to work, causing the filter screen 7 to vibrate. The bottom of the filter screen 7 is connected to the connecting plate 10 through an elastic member 15, and this elastic connection method can enhance the vibration effect. During the vibration process, small particles pass through the filter screen 7 under the combined action of gravity and vibration force, and then enter the extruder 1, while large particles remain on the filter screen 7. This vibration screening method can continuously and effectively screen the material and make the particle size of the material entering the extruder 1 more uniform.

[0036] By setting up the feeding assembly, the sticky materials can be broken up and then screened by the vibration filter 7, which effectively avoids the large particles from blocking the feeding channel, ensures the smoothness of the feeding, and thus maintains the continuity and stability of production.

[0037] Reference Figure 1-Figure 4A fixed plate 9 is fixedly connected to the inside of the feed bin 2, a driving motor 11 is provided on the top of the fixed plate 9, a rod body 12 is fixedly connected to the output end of the driving motor 11, the rod body 12 and the connecting rod 13 are both rotatably connected to the fixed plate 9, and the rod body 12 and the connecting rod 13 are connected through a synchronous belt transmission.

[0038] The driving motor 11 is used as a power source. After starting, its output end drives the rod body 12 to rotate. Since the rod body 12 and the connecting rod 13 are connected by a synchronous belt transmission, and both are rotatably connected to the fixed plate 9, the rotational movement of the rod body 12 can be transmitted to the connecting rod 13 through the synchronous belt, so that the connecting rod 13 rotates accordingly. The multiple breaking rods 8 fixedly connected to the top of the connecting rod 13 will rotate in the feed bin 2 as the connecting rod 13 rotates, and the recycled rubber material in the feed bin 2 is broken up.

[0039] Reference Figure 1-Figure 3 A feed port 3 is provided at the top of the feed bin 2, and a buffer assembly is provided below the feed port 3. The buffer assembly includes a feed cone 4. The outer wall of the feed cone 4 is smoothly provided. A telescopic rod 5 is fixedly connected to the bottom of the feed cone 4. A spring 6 is provided on the outer wall of the telescopic rod 5. The bottom end of the telescopic rod 5 is fixedly connected to a fixed plate 9.

[0040] When the recycled rubber material enters the feed bin 2 from the feed port 3, it will first fall on the discharge cone 4 of the buffer component. The outer wall of the discharge cone 4 is smooth, allowing the material to slide down its inclined surface relatively smoothly. Since the falling material has a certain impact force, the discharge cone 4 will be compressed downward under the action of the force. At this time, the telescopic rod 5 connected to the bottom of the discharge cone 4 will shrink, and the spring 6 sleeved on the outer wall of the telescopic rod 5 will be compressed. The spring 6 and the telescopic rod 5 work together to absorb part of the impact force generated by the falling material, thereby achieving a buffering effect. When the impact force of the material is reduced, the spring 6 will return to its original state under the action of its own elastic force, so that the discharge cone 4 returns to its initial position, ready to welcome the entry of the next batch of materials.

[0041] First, the buffer assembly effectively reduces the impact force of the material on the equipment components through the buffering effect of the spring 6 and the telescopic rod 5, thereby extending the service life of the equipment and reducing the maintenance cost of the equipment;

[0042] Secondly, through the guidance of the discharge cone 4 and the shock absorption of the buffer component, the material can enter the disintegration area in the feed bin 2 in a more orderly manner, which is conducive to the stability of subsequent disintegration and screening and other feeding processes, thereby improving the feeding quality and production efficiency of the entire recycled rubber molding equipment.

[0043] Reference Figure 3-Figure 4The driving motor 11 is located on one side of the telescopic rod 5, and the plurality of breaking rods 8 are located between the fixed plate 9 and the filter screen 7. One end of the connecting rod 13 extends through and extends to the bottom of the filter screen 7 and is fixedly connected with a feeding roller 14, which is arranged in a spiral shape.

[0044] After the material is screened by the filter screen 7, the granular material falls down, and the spiral discharge roller 14 uses its special spiral structure to generate a driving force on the falling particles during the rotation process. This driving force can make the falling particles move quickly and orderly to the feeding direction of the extruder 1, thereby accelerating the feeding speed.

[0045] Reference Figure 6 A heating box 16 is provided on the outer wall of the bottom end of the feed bin 2 , and an electric heating wire 17 is provided inside the heating box 16 .

[0046] The electric heating wire 17 works in the heating box 16 to heat the outer wall of the bottom end of the feed bin 2. The heat is gradually transferred from the bottom of the feed bin 2 to the inside to preheat the recycled rubber material. Since the heating box 16 surrounds the outer wall of the bottom end of the feed bin 2, it can transfer heat to the contacted bin wall part more evenly. This preheating method is to conduct heat from the bin wall to the material through heat conduction, so that the material temperature reaches a suitable range before entering the subsequent processing link.

[0047] Working principle: The rubber material enters from the feed port 3 and first contacts the buffer assembly. The material can slide smoothly due to the smooth outer wall of the material discharge cone 4 in the buffer assembly. At the same time, the impact force of the falling material presses the discharge cone 4 downward, driving the telescopic rod 5 to contract and the spring 6 to compress. The two work together to absorb the impact force, reduce the impact on the equipment components, protect the equipment, and extend the service life. When the impact force decreases, the spring 6 recovers and the discharge cone 4 returns to its original position. Then, the material enters the scattered area in the feed bin 2.

[0048] In the feed bin 2, the drive motor 11 is started, and the output end drives the rod body 12 to rotate, and the connecting rod 13 is rotated through the synchronous belt, so that the multiple breaking rods 8 stir and impact the material, especially for the recycled rubber particles bonded by the sticky components, breaking up the large agglomerates into small particles to prevent large pieces of material from entering the subsequent process.

[0049] The broken materials fall on the filter screen 7, and the vibration motor 18 is started. Since the bottom of the filter screen 7 is connected to the connecting plate 10 through the elastic member 15, the vibration effect is enhanced. Under the action of vibration and gravity, small particles pass through the filter screen 7 and enter the extruder 1, and large particles remain on the filter screen 7, ensuring that the particle size of the materials entering the extruder 1 is uniform, avoiding large particles from blocking the feed channel, and maintaining production continuity and stability.

[0050] After the equipment has been running for a period of time, it is stopped and the staff can open the relevant inspection port of the feed bin 2 (which is the prior art and not shown in the figure). Since large particles of material remain on the filter screen 7, the large particles can be cleaned off the filter screen 7 manually using tools (such as a shovel, a brush, etc.), or a negative pressure adsorption tube can be introduced through the feed port 3, and the large particles can be sucked away by an external negative pressure adsorption device.

[0051] After being screened by the filter screen 7, the granular material falls down, and the spiral feed roller 14 located below the filter screen 7 uses its special spiral structure to push the falling particles during the rotation process, so that the particles move quickly and orderly in the feeding direction of the extruder 1, thereby accelerating the feeding speed.

[0052] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
