Description

Technical Field

[0001] This utility model relates to the field of mixing machine technology, and in particular to a mixing machine for uniform mixing. Background Technology

[0002] A mixing mill is a high-efficiency and powerful industrial mixing equipment, mainly used for processing polymer materials such as rubber and plastics. Its core function is to subject polymers and compounding agents to strong shearing, extrusion and kneading under heat and pressure. Common types of mixing mills include closed internal mixers and open mixing mills.

[0003] Mixing mills are important devices in alloy research and development. Among them, open mills are used to mix polymers that make the alloy stronger. The research and development of this polymer usually uses small open mills. When mixing polymers, high-temperature preheating is often required on the extrusion rollers. During the processing, workers need to manually remove the polymer and put it back into the open mill for mixing to ensure that the polymer is mixed evenly. However, workers may be burned at high temperatures, which cannot meet the needs of workers. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a uniform mixing machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A homogenizing mixer includes an open mill, a support frame fixedly mounted on the open mill, a rotary motor fixedly mounted on the support frame, a threaded rod fixedly mounted on the motor shaft of the rotary motor, a lifting block threadedly connected to the threaded rod, a rotating shaft rotatably mounted on the lifting block, a tilting shovel fixedly mounted on the rotating shaft, a bidirectional screw rotatably mounted on the open mill, two mutually symmetrical push blocks threadedly connected to the bidirectional screw, a rotating assembly mounted on the lifting block, and a control mechanism for controlling the rotation of the bidirectional screw mounted on the support frame.

[0007] Preferably, the control mechanism includes a second rotating shaft rotatably mounted on a support frame. The second rotating shaft is connected to the threaded rod via a belt drive assembly. Both the second rotating shaft and the bidirectional screw are fixedly mounted with bevel gears, and the two bevel gears mesh with each other for transmission.

[0008] Preferably, the rotating assembly includes a third rotating shaft rotatably mounted on the lifting block, the third rotating shaft being connected to the first rotating shaft via a second belt drive assembly, a first spur gear being fixedly mounted on one end of the third rotating shaft, and a rack being fixedly mounted on the lower end of the support frame, the first spur gear meshing with the rack.

[0009] Preferably, a rotary motor is fixedly installed on the open mill, a rotating rod is fixedly installed on the output shaft of the rotary motor, a second spur gear is fixedly installed on the rotating rod, two rotating rods are rotatably installed on the open mill, a third spur gear is fixedly installed on each of the two rotating rods, the two third spur gears mesh with the second spur gear, and a cleaning block is fixedly installed on each of the two rotating rods.

[0010] Preferably, a plurality of feet are fixedly installed at the lower end of the open mill, and the lower ends of the plurality of feet are provided with anti-slip patterns.

[0011] Preferably, a slide bar is fixedly installed on the open mill, and both push blocks are slidably connected to the slide bar.

[0012] 1. Compared with the prior art, the beneficial effects of this utility model are: by rotating the threaded rod, the lifting block drives the tilting shovel to descend until it contacts the rotating roller on the open mill and shears the polymer raw material, so that the polymer enters the tilting shovel during the subsequent rotation. During this process, the belt drive assembly and the bevel gear drive the bidirectional screw to rotate, thereby causing the pushing block to polymerize the raw material, which is then more conveniently collected by the tilting shovel.

[0013] 2. After the material is collected by the shovel, it rises through the threaded rod. Driven by the spur gear and rack, and with the cooperation of the belt drive assembly, the rotating shaft and the shovel rotate, thus dropping the agglomerated material from the rear end of the shovel into the open mill, completing the turning of the material. Therefore, the automatic turning of the material can be completed, reducing the risk of burns to workers. Attached Figure Description

[0019] Reference Figures 1-4 A uniform mixing mill includes an open mill 1, which is existing technology. The open mill 1 is driven by a drive motor to drive a rotating roller, which uniformly mixes the raw materials placed on the rotating roller. The details are not elaborated here. A support frame 9 is fixedly installed on the open mill 1. A rotary motor 2 is fixedly installed on the support frame 9. The rotary motor 2 is existing technology and can rotate an object connected to its output shaft. A threaded rod 3 is fixedly installed on the motor shaft of the rotary motor 2. A lifting block 4 is threadedly connected to the threaded rod 3. A rotating shaft 5 is rotatably installed on the lifting block 4. There is a friction layer at the rotatable connection between the rotating shaft 5 and the lifting block 4. This friction layer is a limiting block with a self-locking function. Therefore, the rotating shaft 5 and the tipping shovel 6 will not shake or rotate automatically due to up and down movement. The tipping shovel 6 is fixedly installed on the rotating shaft 5. A bidirectional screw 7 is rotatably installed on the open mill 1. Two mutually symmetrical push blocks 8 are threadedly connected to the bidirectional screw 7. A rotating component is installed on the lifting block 4. A control mechanism for controlling the rotation of the bidirectional screw 7 is installed on the support frame 9.

[0020] By starting the rotary motor 2, the threaded rod 3 is driven to rotate, which causes the lifting block 4 to descend. When the lifting block 4 descends, it drives the rotating shaft 5 and the tipping shovel 6 to descend simultaneously until they contact the rotating roller of the open mill 1. The tipping shovel 6 cuts the raw material and allows the raw material to enter the tipping shovel 6 by its own weight, thus completing the automatic agglomeration of the raw material.

[0021] The control mechanism includes a rotating shaft 10 rotatably mounted on the support frame 9. The rotating shaft 10 is connected to the threaded rod 3 via a belt drive assembly 11. The belt drive assembly 11 consists of two pulleys and a belt body, which can drive the rotation of the threaded rod 3, causing the rotating shaft 10 to rotate. Both the rotating shaft 10 and the bidirectional screw 7 are fixedly mounted with bevel gears 12, and the two bevel gears 12 mesh with each other for transmission.

[0022] When the lifting block 4 descends, the threaded rod 3 drives the rotating shaft 10 to rotate through the belt drive assembly 11, which in turn drives the bevel gear 12 on it to rotate. This causes the meshing bevel gear 12 to rotate, which in turn drives the bidirectional screw 7 to rotate. The rotation of the bidirectional screw 7 drives the two push blocks 8 to move closer to the center, causing the raw material to move from being dispersed to being gathered in the center. When the turning shovel 6 contacts the rotating roller, the push block 8 moves to the appropriate position, and the raw material matches the turning shovel 6, which further facilitates the cutting work of the turning shovel 6.

[0023] The rotating assembly includes a rotating shaft 13 rotatably mounted on the lifting block 4. The rotating shaft 13 is connected to the rotating shaft 5 via a belt drive assembly 14. The belt drive assembly 14 consists of two pulleys and a belt body, which can drive the rotation of the rotating shaft 13, causing the rotating shaft 5 to rotate. A spur gear 15 is fixedly mounted on one end of the rotating shaft 13, and a rack 16 is fixedly mounted on the lower end of the support frame 9. The spur gear 15 meshes with the rack 16.

[0024] When the rotary motor 2 starts, causing the threaded rod 3 to rotate and drive the lifting block 4 to descend, the meshing of the spur gear 15 and rack 16 on the rotating shaft 3 13 of the lifting block 4 causes the rotating shaft 3 13 to rotate, which in turn drives the rotating shaft 5 to rotate through the belt drive assembly 2 14. This causes the turning shovel 6 to rotate, changing from a vertical state to a horizontal state that can match the rotating roller. When the rotary motor 2 starts, causing the threaded rod 3 to rotate in the opposite direction, the lifting block 4 rises. Due to the meshing of the spur gear 15 and rack 16, the spur gear 15 drives the rotating shaft 3 13 to rotate in the opposite direction, thus changing the turning shovel 6 from a horizontal state to a vertical state. During this process, the raw materials that are agglomerated in the turning shovel 6 fall off the turning shovel 6 by their own weight and re-enter the rotating roller to continue the mixing process. This completes the automatic turning operation.

[0025] A rotary motor 17 is fixedly installed on the open mill 1. The rotary motor 17 is existing technology and can make an object connected to its output shaft rotate. A rotating rod 18 is fixedly installed on the output shaft of the rotary motor 17. A spur gear 29 is fixedly installed on the rotating rod 18. Two rotating rods 20 are rotatably installed on the open mill 1. A spur gear 31 is fixedly installed on each of the two rotating rods 20. Both spur gears 321 mesh with spur gear 29. A cleaning block 22 is fixedly installed on each of the two rotating rods 20.

[0026] After processing is completed, the rotating motor 17 is started, which drives the rotating rod 18 to rotate, thus causing the fixedly installed spur gear 2 19 to rotate, thereby causing the meshing spur gear 3 21 to rotate, which causes the rotating rod 20 to drive the cleaning block 22 to rotate, thereby causing the cleaning block 22 to contact the rotating roller, thus cleaning the rotating roller.

[0027] Multiple feet are fixedly installed at the lower end of the open mill 1. The lower ends of the multiple feet are all equipped with anti-slip textures. With the use of the feet, the operator can stably place the device in the designated position. A sliding rod is fixedly installed on the open mill 1. Two push blocks 8 are slidably connected to the sliding rod. The sliding rod has a limiting function, which allows the two push blocks 8 to slide stably without shaking.

[0028] In this invention, the working principle is as follows: Starting the rotary motor 2 drives the threaded rod 3 to rotate, causing the lifting block 4 to descend. As the lifting block 4 descends, it simultaneously drives the rotating shaft 5 and the tipping shovel 6 to descend until they contact the rotating roller of the open mill 1. The tipping shovel 6 cuts the raw material, and the material, by its own weight, enters the tipping shovel 6, thus completing the automatic agglomeration of the raw material. While the lifting block 4 descends, the threaded rod 3 drives the rotating shaft 10 to rotate via the belt drive assembly 11, thereby driving the bevel gear 12 on it to rotate. This, in turn, drives the meshing bevel gear 12 to rotate, causing the bidirectional screw 7 to rotate. The rotation of the bidirectional screw 7 drives the two pushing blocks 8 to move closer together, causing the raw material to move from dispersed to more concentrated. When the tipping shovel 6 contacts the rotating roller, the pushing blocks 8 move to the appropriate position, matching the raw material with the tipping shovel 6, further facilitating the tipping process. The cutting operation of the material shovel 6 is carried out by the following process: When the rotary motor 2 starts, the threaded rod 3 rotates, causing the lifting block 4 to descend. The meshing of the spur gear 15 and rack 16 on the rotating shaft 3 13 of the lifting block 4 causes the rotating shaft 3 13 to rotate. This rotation is transmitted through the belt drive assembly 2 14 to the rotating shaft 5, thus causing the material shovel 6 to rotate and change from a vertical state to a horizontal state that can match the rotating roller. When the rotary motor 2 starts, the threaded rod 3 rotates in the opposite direction, causing the lifting block 4 to rise. Due to the meshing of the spur gear 15 and rack 16, the spur gear 15 drives the rotating shaft 3 13 to rotate in the opposite direction, thus causing the material shovel 6 to change from a horizontal state to a vertical state. During this process, the raw materials that are clumped in the material shovel 6 fall off the material shovel 6 by their own weight and re-enter the rotating roller to continue the mixing process. This completes the automatic material turning operation.
