Description

Technical Field

[0001] This utility model relates to the field of mixer technology, specifically a high- and low-speed mixer for PVC sheet production. Background Technology

[0002] High- and low-speed mixers for PVC sheet production are mixing and stirring equipment specifically designed for the production of polyvinyl chloride (PVC) sheets. They are mainly used to mix various raw materials such as PVC resin, stabilizers, lubricants, fillers, and pigments in a specific ratio to form a dry mix that meets processing requirements. Their core feature is the use of a combination of high and low speed mixing to achieve efficient dispersion, plasticization, and cooling of the raw materials, ensuring the uniformity and stability of the mixture and laying the foundation for subsequent extrusion molding processes.

[0003] Existing patent document CN213382355U discloses a high- and low-speed mixer for PVC sheet production, including a main body. A connecting column is located at the top of the main body, and a motor is installed on one side of the connecting column, located on the inner wall of the top of the main body. A gear is connected to the output end of the motor, and a driven gear connected to the gear is located on the outer side of the connecting column. This invention utilizes a pneumatic cylinder and an electric telescopic rod. Activating the electric telescopic rod extends and retracts, while simultaneously, a spring is extended and retracted by a ball pressed against the inner wall of the discharge port, separating the ball from the discharge port. This allows material to enter and exit the collection box from the discharge port. After collection, a rotating door on one side of the main body is manually opened, and then the pneumatic cylinder is activated to push the collection box outwards from the main body, making material removal convenient and simple.

[0004] However, while existing high- and low-speed mixers for PVC sheet production can achieve high-speed and low-speed mixing of materials through their mixing components, cleaning the equipment after mixing is difficult due to the presence of dead corners in the mixing tank. Cleaning typically requires manual entry into the tank to rinse with water or a water gun, which is inefficient and increases the workload for workers. Therefore, we propose a high- and low-speed mixer for PVC sheet production. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4This utility model provides a technical solution: a high and low speed mixer for PVC board production, including a bearing unit 1, the bearing unit 1 including a lifting rod 105, and an installation plate 106 welded to the bottom of the lifting rod 105;

[0026] The mixing unit 2 includes a mounting bracket 201 bolted to the top of the lifting rod 105. A high-speed mixing motor 203 is mounted on the top of the mounting bracket 201. A high-speed mixing shaft 205 is fixed to the drive end of the high-speed mixing motor 203 via a coupling. A mixing blade 206 is welded to the bottom end of the high-speed mixing shaft 205. A water spray nozzle 207 is opened on the outer side of the high-speed mixing shaft 205. A water passage cavity 209 is opened from the outside to the inside of the high-speed mixing shaft 205. A rotary joint 208 is mounted on the outer side of the top of the high-speed mixing shaft 205. A cleaning water pipe 204 is welded to the outer side of the rotary joint 208.

[0027] The drive unit 3 includes a low-speed stirring motor 301 mounted on the top of the mounting bracket 201, and a drive wheel 302 is keyed to the drive end of the low-speed stirring motor 301.

[0028] Furthermore, the bottom of the mounting plate 106 is bolted to the base plate 101, and the bottom of the base plate 101 is threaded with casters 102, which facilitate the movement of the mixer by the workers.

[0029] Furthermore, a limiting groove 103 is provided on one side of the base plate 101, and a mixing tank 104 is installed inside the limiting groove 103. The mixing tank 104 can carry materials, and the limiting groove 103 can play a limiting role when the mixing tank 104 is placed.

[0030] Furthermore, a sealing cover 202 is bolted to the bottom of the mounting bracket 201. A bearing 210 is sleeved on the inner side of the sealing cover 202. A low-speed stirring shaft 211 is interference-fitted on the inner side of the bearing 210. The bearing 210 makes the low-speed stirring shaft 211 more sensitive during rotation, and the sealing cover 202 can play a sealing role.

[0031] Furthermore, a transmission wheel 213 is keyed to the top of the low-speed stirring shaft 211, and a low-speed stirring rod 212 is welded to the bottom of the low-speed stirring shaft 211. When the transmission belt 303 drives the low-speed stirring shaft 211 to rotate through the transmission wheel 213, the low-speed stirring shaft 211 drives the low-speed stirring rod 212 to rotate and perform low-speed stirring of the material.

[0032] Furthermore, a transmission belt 303 is connected to the outer side of the drive wheel 302. The transmission belt 303 is connected to the transmission wheel 213. By starting the low-speed stirring motor 301, the low-speed stirring motor 301 drives the transmission belt 303 to rotate through the drive wheel 302, and the transmission belt 303 drives the low-speed stirring shaft 211 to rotate through the transmission wheel 213.

[0033] Working Principle: After installation, first check the installation, fixation, and safety precautions of this utility model. When using the high- and low-speed mixer for PVC sheet production, the operator adds materials to the mixing drum 104, positioning the mixing drum 104 in the limiting groove 103. Then, the lifting rod 105 is activated, causing the mixing unit 2 to move downwards. At this time, the sealing cover 202 merges with the mixing drum 104. Subsequently, the high-speed mixing motor 203 is activated, driving the high-speed mixing shaft 205 to rotate. Simultaneously, the mixing blades 206 perform high-speed mixing of the materials. Meanwhile, the low-speed mixing motor 301 drives the transmission belt 303 through the drive wheel 302, and the transmission belt 303 drives the low-speed mixing shaft 211 to rotate through the transmission wheel 213. 211 drives the low-speed stirring rod 212 to rotate and stir the material at a low speed, while cleaning the inside of the mixing tank 104. After the stirring is complete, when the material is discharged and the mixing tank 104 needs to be cleaned, the worker connects the cleaning water pipe 204 to the water source. The water source is transported through the cleaning water pipe 204 to the rotary joint 208, and the rotary joint 208 transports the water to the water passage chamber 209 of the high-speed stirring shaft 205. At the same time, the water is sprayed out from the spray nozzle 207, and the sprayed water can wash the mixing tank 104. During the washing process, the high-speed stirring motor 203 drives the high-speed stirring shaft 205 to rotate, so that the sprayed water can thoroughly wash the inside of the mixing tank 104. This completes the use of this utility model. This utility model has a simple structure and is safe and convenient to use.
