Description

Technical Field

[0001] This utility model belongs to the field of ingredient mixing technology, and in particular relates to a polyvinyl chloride heat stabilizer ingredient mixing device. Background Technology

[0002] The PVC heat stabilizer mixing unit is a specialized piece of equipment used in the PVC processing industry. Its core function is to thoroughly and uniformly mix PVC resin powder with heat stabilizer, preparing qualified dry mix for subsequent molding processes such as extrusion, calendering, and injection molding. This ensures that PVC products have good thermal stability, mechanical properties, and appearance quality, making it a core piece of equipment in the front end of PVC processing and production.

[0003] Based on the above, the inventors have discovered the following shortcomings in existing polyvinyl chloride heat stabilizer mixing devices:

[0004] 1. There is no material scooping structure at the lower end of the mixing shaft, so it is impossible to scoop up and mix the material that has settled to the bottom. It is inconvenient to add material scooping measures to the mixing shaft to scoop up and mix the material that has settled to the bottom.

[0005] 2. The mixing shaft is directly mounted on the equipment via bearings, making the disassembly and assembly process of the mixing shaft difficult. It is inconvenient to add detachable assembly measures to the mixing shaft to achieve quick disassembly and replacement. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a polyvinyl chloride heat stabilizer mixing device. This addresses the issues of existing mixing shafts lacking a material scooping structure at the bottom, making it impossible to scoop up and mix materials that have settled at the bottom. It also avoids the inconvenience of adding material scooping measures to the mixing shaft for mixing, and the difficulty of disassembling and assembling the mixing shaft due to its direct mounting via bearings. Furthermore, it makes it difficult to add detachable assembly measures to the mixing shaft for quick disassembly and replacement.

[0007] The purpose and effectiveness of this utility model's polyvinyl chloride heat stabilizer mixing device are achieved through the following specific technical means:

[0008] A polyvinyl chloride heat stabilizer mixing device includes a device body; the device body is provided with a mixing shaft, a regular hexagonal rod is provided on the bottom end face of the mixing shaft, a threaded blind hole is opened on the bottom end face of the regular hexagonal rod of the mixing shaft, a material shovel fan is sleeved on the lower end of the regular hexagonal rod of the mixing shaft, a bearing cylinder with a through regular hexagonal hole is provided at the center of the material shovel fan, and inclined shovel plates are arranged in a ring array on the outer circumference of the bearing cylinder of the material shovel fan.

[0009] Furthermore, a semi-cylinder with a rearward-facing plane is provided in front of the top end face of the mixing shaft. The outer circumference of the semi-cylinder of the mixing shaft is threaded. A fitting block is provided in the middle of the rear end face of the semi-cylinder of the mixing shaft. An insertion hole with a through-hole is provided in the middle of the fitting block of the mixing shaft.

[0010] Furthermore, an anti-detachment fixing post is installed inside the threaded blind hole of the mixing shaft, an anti-detachment circular plate is provided at the lower part of the anti-detachment fixing post, a threaded post is provided on the top end face of the anti-detachment circular plate of the anti-detachment fixing post, and a regular hexagonal prism is provided on the bottom end face of the anti-detachment circular plate of the anti-detachment fixing post.

[0011] Furthermore, a mixing spiral plate is fitted onto the regular hexagonal rod of the mixing shaft, and a bearing cylinder with a through regular hexagonal hole is provided at the center of the mixing spiral plate. Spiral plates are provided on the outer circumference of the bearing cylinder of the mixing spiral plate, and the outer surface of the spiral plate of the mixing spiral plate is a frustum-shaped structure.

[0012] Furthermore, a rotating assembly column is fitted onto the semi-cylinder of the mixing shaft. A limiting circular plate is provided in the middle of the rotating assembly column. A fixing column is provided on the top end face of the limiting circular plate of the rotating assembly column. A regular hexagonal prism is provided on the top end face of the fixing column of the rotating assembly column. A semi-cylinder with a plane facing forward is provided behind the bottom end face of the limiting circular plate of the rotating assembly column. A through-hole fitting groove is opened in the middle of the front end face of the semi-cylinder of the rotating assembly column. A thread is opened on the outer circumference of the semi-cylinder of the rotating assembly column.

[0013] Furthermore, an assembly locking cylinder is threadedly installed on the semi-cylinder of the rotating assembly column. The assembly locking cylinder has a threaded inner circumference and a regular hexagonal structure on its outer circumference. A threaded hole that runs through the front and rear of the assembly locking cylinder is provided on its front wall.

[0014] Furthermore, an assembly anti-rotation post is installed inside the threaded hole of the assembly locking cylinder, a threaded post is provided behind the assembly anti-rotation post, a locking ring plate is provided on the outer circumference of the front end of the threaded post of the assembly anti-rotation post, and a regular hexagonal groove is opened on the front end face of the threaded post of the assembly anti-rotation post.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The material shovel fan sleeve rotates synchronously on the batching and mixing shaft, allowing the material shoveled at the bottom to be easily scooped up and mixed. This solves the problem that the mixing shaft has no material shovel structure at the bottom, making it impossible to scoop up and mix the material at the bottom, and making it inconvenient to install material shovel measures on the mixing shaft to scoop up and mix the material at the bottom.

[0017] The semi-cylinder of the mixing shaft and the semi-cylinder of the rotating assembly column can be easily matched. The locking sleeve can be used to lock the mixing shaft and the rotating assembly column at the matching point to prevent them from falling off. This solves the problem that the mixing shaft is directly installed on the equipment through the bearing, which makes the disassembly and assembly process of the mixing shaft difficult and makes it inconvenient to add detachable assembly measures to the mixing shaft to achieve quick disassembly and replacement.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0026] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown:

[0027] This utility model provides a polyvinyl chloride (PVC) heat stabilizer mixing device, including a device body 1. The device body 1 is provided with a mixing shaft 2 for facilitating the mixing of PVC heat stabilizer and supporting various components. A regular hexagonal rod is provided on the bottom end face of the mixing shaft 2 to facilitate the synchronous rotation of the material shovel fan 3 and the mixing spiral plate 5. A threaded blind hole is opened on the bottom end face of the regular hexagonal rod of the mixing shaft 2 to facilitate the installation of the anti-detachment fixing column 4 by thread. The material shovel fan 3 is sleeved on the lower end of the regular hexagonal rod of the mixing shaft 2 to facilitate the rotation of the material shovel fan 3 through the mixing shaft 2. A bearing cylinder with a through-hole regular hexagonal hole is provided in the center of the material shovel fan 3 to facilitate the insertion of the regular hexagonal rod of the mixing shaft 2. An inclined shovel plate is arranged in a circular array around the outer circumference of the bearing cylinder of the material shovel fan 3 to facilitate the material shovel fan 3 to scoop up and mix the material at the bottom. The top end face of the mixing shaft 2 is... A semi-cylinder with a flat rearward orientation is provided at the front, which facilitates the engagement with the semi-cylinder of the rotating assembly column 6 to form a cylindrical structure. The outer circumference of the semi-cylinder of the mixing shaft 2 is threaded, which facilitates the assembly of the locking cylinder 7 through threaded installation. A mating block is provided in the middle of the rear end face of the semi-cylinder of the mixing shaft 2, which facilitates the engagement with the mating groove of the rotating assembly column 6. An insertion hole with a through-hole is provided in the middle of the mating block of the mixing shaft 2, which facilitates the insertion of the anti-rotation column 8. An anti-detachment fixing column 4 is installed inside the threaded blind hole of the mixing shaft 2, which facilitates the anti-detachment of the material shovel fan 3. An anti-detachment circular plate is provided at the lower part of the anti-detachment fixing column 4, which facilitates the limiting and anti-detachment of the material shovel fan 3. A threaded column is provided on the top end face of the anti-detachment circular plate of the anti-detachment fixing column 4, which facilitates the threaded installation of the anti-detachment fixing column 4. A regular hexagonal prism is provided on the bottom end face of the anti-detachment circular plate of the anti-detachment fixing column 4, which facilitates the rotation and disassembly of the anti-detachment fixing column 4 using tools.

[0028] The mixing shaft 2 has a hexagonal rod fitted with a mixing spiral plate 5, facilitating synchronous rotation of the mixing shaft 2 and the mixing spiral plate 5. The mixing spiral plate 5 has a support cylinder with through-holes at the top and bottom, allowing the hexagonal rod of the mixing shaft 2 to be inserted. Spiral plates are arranged around the outer circumference of the support cylinder of the mixing spiral plate 5, facilitating the mixing of materials. The outer surface of the spiral plates of the mixing spiral plate 5 is a frustum-shaped structure, allowing materials to be spirally lifted upwards and then falling downwards for mixing. A rotating assembly column 6 fits onto the semi-cylinder of the mixing shaft 2, facilitating the driving of the mixing shaft. The rotating shaft 2 rotates. A limiting circular plate is provided in the middle of the rotating assembly column 6 to facilitate the limiting of the bearing and the assembly locking cylinder 7. A fixing column is provided on the top end face of the limiting circular plate of the rotating assembly column 6, allowing the rotating assembly column 6 to rotate by being mounted on the equipment housing via the bearing. The top end face of the fixing column of the rotating assembly column 6 is provided with a regular hexagonal prism, facilitating the synchronous rotation of the rotating assembly column 6 with an external power unit. A forward-facing semi-cylinder is provided behind the bottom end face of the limiting circular plate of the rotating assembly column 6, facilitating its engagement with the semi-cylinder of the mixing shaft 2. The semi-cylinder of the rotating assembly column 6... A through-groove groove is provided in the middle of the front face to facilitate the insertion and engagement of the mating block of the mixing shaft 2. The outer circumference of the semi-cylindrical part of the rotating assembly column 6 is threaded to facilitate the threaded installation of the locking cylinder 7. The locking cylinder 7 is threaded onto the semi-cylindrical part of the rotating assembly column 6 to secure the mating point between the mixing shaft 2 and the rotating assembly column 6, preventing detachment. The inner circumference of the locking cylinder 7 is threaded for easy assembly and disassembly. The outer circumference of the locking cylinder 7 has a regular hexagonal structure to facilitate rotation and disassembly using tools. The assembly locking cylinder 7 has a through threaded hole on its front wall, which facilitates the installation of the anti-rotation pin 8 by thread. The anti-rotation pin 8 is installed inside the threaded hole of the assembly locking cylinder 7 to prevent the assembly locking cylinder 7 from rotating. A threaded post is provided at the rear of the anti-rotation pin 8 to facilitate the installation of the anti-rotation pin 8 by thread. A locking ring plate is provided on the outer circumference of the front end of the threaded post of the assembly anti-rotation pin 8 to facilitate the locking of the anti-rotation pin 8 onto the assembly locking cylinder 7. A regular hexagonal groove is provided on the front end face of the threaded post of the assembly anti-rotation pin 8 to facilitate the rotation and disassembly of the anti-rotation pin 8 by tools.

[0029] The specific usage and function of this embodiment are as follows:

[0030] In this utility model, when... Figure 1As shown, when the device body 1 is in use, the rotating assembly column 6 is mounted on the equipment housing via bearings, allowing the rotating assembly column 6 to rotate. The hexagonal prism of the rotating assembly column 6 is connected to an external power device, thereby driving the rotating assembly column 6 to rotate. The rotating assembly column 6 drives the batching and mixing shaft 2 to rotate synchronously, which in turn drives the material shovel fan 3 and the mixing spiral plate 5 to rotate synchronously. The material shovel fan 3 and the mixing spiral plate 5 then mix the polyvinyl chloride heat stabilizer. Note that the shovel plate of the material shovel fan 3 contacts the bottom of the material container, facilitating the shoveling and mixing of the settled material, effectively breaking up the material accumulation layer. This solves the problem that the mixing shaft lacks a material shovel structure at the bottom, making it impossible to shovel and mix the settled material. Figure 1 As shown, when the mixing shaft 2 is disassembled from the rotating assembly column 6, the assembly anti-rotation column 8 is engaged with the assembly locking cylinder 7 by rotating the assembly anti-rotation column 8 with a tool. This causes the assembly anti-rotation column 8 to move forward and disengage from the insertion hole of the mixing shaft 2 through the thread engagement. This releases the assembly anti-rotation column 8 from its anti-rotation function on the assembly locking cylinder 7. Then, the assembly locking cylinder 7 is engaged with the semi-cylindrical thread of the mixing shaft 2 and the rotating assembly column 6 by rotating the assembly anti-rotation column 6. This causes the assembly locking cylinder 7 to descend and leave the joint between the mixing shaft 2 and the rotating assembly column 6 through the thread engagement, as shown in the diagram. Figure 5 As shown, the mixing shaft 2 is then removed from the rotating assembly column 6, thus completing the disassembly of the mixing shaft 2. The reverse operation is the installation operation of the mixing shaft 2. This solves the problem that the mixing shaft is directly installed on the equipment through the bearing, which makes the disassembly and assembly process of the mixing shaft difficult.

[0031] Example 2: The difference from Example 1 is that the regular hexagonal prism of the anti-detachment fixing post 4 can also be set as a regular heptagonal prism, so that the anti-detachment fixing post 4 can only be rotated by a special tool that works with the regular heptagonal prism, thus preventing non-workers from rotating and disassembling the anti-detachment fixing post 4.

[0032] Example 3: The difference from Example 1 is that the regular hexagonal groove of the assembly anti-rotation column 8 can also be set as a regular heptagonal groove. This makes it necessary to use a special tool that cooperates with the regular heptagonal groove to rotate the assembly anti-rotation column 8, thus preventing non-workers from rotating and disassembling the assembly anti-rotation column 8.
