Description

Technical Field

[0001] This utility model relates to the field of PVC material production technology, specifically to a mixing device for toughening PVC materials. Background Technology

[0002] The mixing device for toughening PVC materials is a key piece of equipment in the PVC processing production line. It is widely used in the production of PVC products such as pipes, profiles, and sheets. In order to improve the toughness and impact resistance of PVC, toughening agents, antioxidants and other additives need to be added during the production process. The uniformity of mixing of additives and PVC substrate directly determines the performance of the final product. If the mixing is uneven, it will lead to insufficient local toughness of PVC material, resulting in cracking, embrittlement and other problems.

[0003] Currently, most PVC mixing devices on the market use a single stirring shaft with stirring blades. This traditional device has a major problem: the stirring blades can only turn over local materials, and the material at the bottom of the mixing tank is difficult to turn to the top, forming a mixing dead zone. This leads to uneven mixing of toughening additives and PVC substrate, which not only requires extending the mixing time to improve uniformity, but may also cause the material to overheat and degrade due to prolonged stirring. At the same time, PVC material has a certain degree of stickiness and easily sticks to the inner wall of the mixing tank during the stirring process. Traditional devices lack an effective automatic cleaning structure, requiring manual disassembly and cleaning, which is time-consuming and labor-intensive, and may also lead to contamination of the next batch of material due to incomplete cleaning. In addition, some devices use a fixed connection for the tank lid, which is inconvenient to disassemble and reassemble, further increasing the difficulty of cleaning and maintenance.

[0004] Therefore, a mixing device for toughening PVC materials is proposed to solve the problem of low mixing efficiency. Utility Model Content

[0027] Please see Figure 1-4 This utility model provides a technical solution: a mixing device for toughening PVC materials, including a mixing tank 1, a tank cover 2 is movably installed on the top of the mixing tank 1 by bolts, and a first stirring component 3 and a second stirring component 4 are arranged inside the mixing tank 1.

[0028] Furthermore, the bottom of the bucket lid 2 is fitted into the outside of the mixing bucket 1 for sealing, and the top of the bucket lid 2 is hinged with a discharge cover 201 for feeding materials; the bottom of the mixing bucket 1 is provided with a discharge port 6 with a solenoid valve for discharging materials, and the bottom of the mixing bucket 1 is fixedly installed with a support leg 7 for supporting the device.

[0029] Please see Figure 3Furthermore, the first stirring assembly 3 includes a rotating shaft 301 rotatably mounted inside the lid 2, the rotating shaft 301 being located at the center of the lid 2. One end of the rotating shaft 301 extending into the mixing tank 1 is fixedly mounted with a mounting box 302. Inside the mounting box 302, a rotating shaft 303 located on the same axis as the rotating shaft 301 is rotatably mounted. One end of the rotating shaft 303 extending out of the mounting box 302 is fixedly mounted with a recess 305. The rotating shaft 303 is located at... A bevel gear 304 is fixedly installed at one end inside the mounting box 302. A rotating shaft 306 is rotatably installed inside the mounting box 302. The rotating shaft 306 is located on the left and right sides of the rotating shaft 303. A bevel gear 307 that meshes with the bevel gear 304 is fixedly installed at one end of the rotating shaft 306 inside the mounting box 302. Several material turning rods 308 are fixedly installed at one end of the rotating shaft 306 extending out of the mounting box 302. The material turning rods 308 are used to stir the upper material.

[0030] The material turning bar 308 stirs the upper layer material and the stirring plate 402 stirs the lower layer material respectively, forming an upper and lower circulation mixing, which improves the mixing efficiency.

[0031] Furthermore, one end of the rotating shaft 301 extending out of the barrel cover 2 is fixedly connected to the output end of the motor 309. The motor 309 is fixedly installed on the top of the barrel cover 2. The end of the turning rod 308 away from the rotating shaft 306 is flat, which is used to increase the turning area.

[0032] Motor 309 is used to drive shaft 301; the flat end of the turning rod 308 increases the contact area with the upper material, improves the turning efficiency, and can more fully break up material agglomerates, further improving the mixing uniformity and avoiding the dispersion effect of toughening additives due to material clumping.

[0033] Please see Figure 4 Furthermore, the second stirring assembly 4 includes a fourth rotating shaft 401, which is rotatably installed inside the mixing tank 1 and located on the same axis as the first rotating shaft 301. Several stirring blades 402 are fixedly installed on the outer wall of one end of the fourth rotating shaft 401 inside the mixing tank 1 for stirring the lower layer of materials. A protrusion 404 is fixedly installed on one end of the fourth rotating shaft 401 near the concave block 305, and the protrusion 404 is used to engage the concave block 305.

[0034] The second rotating shaft 303 and the fourth rotating shaft 401 of the first stirring component 3 are engaged by the concave block 305 and the convex block 404 to achieve power linkage. The material turning rod 308 and the stirring plate 402 operate simultaneously to avoid uneven mixing caused by inconsistent stirring rhythms.

[0035] Furthermore, one end of the rotating shaft 401 extending out of the mixing tank 1 is fixedly connected to the output end of the motor 405. The motor 405 is fixedly installed at the bottom of the mixing tank 1. A turning block 403 is fixedly installed on the top of the stirring plate 402 to increase the stirring area. The stirring plate 402 is a plate with an inclined angle for turning the material.

[0036] Motor 2 405 is used for rotating shaft 401. The inclined stirring blade 402 can generate an upward thrust, which can quickly turn the bottom material to the top. Together with the turning block 403, it increases the mixing area and improves the turning efficiency of the bottom material, solving the problem of the bottom material being difficult to mix in traditional devices.

[0037] Furthermore, the first motor 309 and the second motor 405 rotate in opposite directions. The first motor 309 is used to drive the mounting box 302 to rotate, and the second motor 405 is used to drive the protrusion 404 to rotate.

[0038] Motor 1 309 and Motor 2 405 rotate in opposite directions; Motor 1 309 drives the mounting box 302 to revolve, and Motor 2 405 drives the protrusion 404 to drive the rotating shaft 2 303 to rotate, realizing the main body of the turning bar 308 to revolve and the individual rotation, enhancing the stirring effect of the upper material, and further improving the mixing uniformity and efficiency.

[0039] Please see Figure 5 Furthermore, the mixing tank 1 is also provided with a cleaning component 5. The cleaning component 5 includes a mounting bracket 501 that is rotatably mounted on the outside of the rotating shaft 301. Rotating blocks 502 are rotatably mounted on both ends of the mounting bracket 501 away from the rotating shaft 301. Several cleaning rollers 504 are fixedly mounted on the bottom of the rotating blocks 502. The cleaning rollers 504 are in contact with the inner wall of the mixing tank 1 and are used to clean the tank wall.

[0040] Mounting frame 501 revolves with rotating shaft 301, driving cleaning roller 504 to move along the inner wall of mixing tank 1. Cleaning roller 504 adheres to the tank wall and can clean the adhering material in real time, avoiding the difficulty of cleaning after the material residue hardens, and reducing material waste. The rotation cleaning of cleaning roller 504 does not require an additional power source. It achieves synchronous cleaning with the power of the stirring component, simplifying the device structure.

[0041] Furthermore, a transmission gear 503 is fixedly installed on the side of the rotating block 502 away from the cleaning roller 504, and an annular rack 505 is fixedly installed on the inner wall of the barrel cover 2, with the transmission gear 503 meshing with the annular rack 505.

[0042] The transmission gear 503 meshes with the ring rack 505, converting the revolution of the mounting frame 501 into the rotation of the rotating block 502, which drives the cleaning roller 504 to rotate and rub against the barrel wall, thus improving the cleaning effect.

[0043] The input terminals of both Motor 1 (309) and Motor 2 (405) described in this article are electrically connected to an external power source.

[0044] In actual operation, when this device is used, open the material feeding cover 201 hinged to the top of the barrel cover 2, and put the toughened PVC material and the required additives into the mixing barrel 1; start motor 1 309 and motor 2 405, which rotate in opposite directions. Motor 1 309 drives shaft 1 301 to rotate inside the barrel cover 2. Shaft 1 301 drives the mounting box 302 at the lower end to rotate synchronously. Shaft 2 303 inside the mounting box 302 revolves with the mounting box 302. At the same time, motor 2 405 drives shaft 401 to rotate. The protrusion 404 at the top of shaft 401 engages with the concave block 305 at the bottom of shaft 2 303, causing shaft 2 303 to rotate on its own axis.

[0045] When the second rotating shaft 303 rotates, the first bevel gear 304 at one end drives the second bevel gear 307 meshing on both sides to rotate. The second bevel gear 307 drives the third rotating shaft 306 to rotate. The material turning rod 308 extending from the mounting box 302 of the third rotating shaft 306 rotates accordingly. The end of the material turning rod 308 away from the third rotating shaft 306 is flat, increasing the contact area with the upper material and turning and stirring the upper material in the mixing tank 1. At the same time, the fourth rotating shaft 401 drives the external stirring plate 402 to rotate. The stirring plate 402 is a plate with an inclined angle. Together with the top material turning block 403, it turns the material at the bottom of the mixing tank 1 upward, realizing the circulation and mixing of the upper and lower materials.

[0046] During the mixing process, the mounting bracket 501 on the outside of the rotating shaft 301 revolves with the rotating shaft 301. The transmission gear 503 on one side of the rotating block 502 at both ends of the mounting bracket 501 meshes with the annular rack 505 on the inner wall of the barrel cover 2, causing the rotating block 502 to rotate. The cleaning roller 504 at the bottom of the rotating block 502 rotates accordingly and adheres to the inner wall of the mixing barrel 1, cleaning the material adhering to the barrel wall in real time. After mixing is completed, the discharge port 6 with a solenoid valve at the bottom of the mixing barrel 1 is opened to discharge the mixed toughened PVC material. If a thorough cleaning of the device is required, the barrel cover 2 can be removed by bolts to further maintain the interior of the mixing barrel 1 and the mixing components.
