Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] See Figures 1 to 7 A feeding device for the production of PVC hollow composite tiles includes a reaction vessel 1, a valve 14, at least three support bases 3, a stirring assembly 11, a screening assembly 22, and a vibration assembly 23.

[0033] The reactor 1 is the main container of the device, placed vertically. Inside, a stirring shaft 2 is installed vertically. The stirring shaft 2 is rotatably engaged with the inner wall of the reactor 1 via bearings, allowing it to rotate around its vertical axis to provide power for mixing materials inside the reactor. The bottom of the reactor 1 is welded to a support base 3, which is located below the bottom of the reactor 1, bearing its weight and providing support to maintain its position during operation. Multiple screens 4 are distributed along the stirring shaft 2, perpendicular to the shaft and evenly arranged. A circular fixing ring 5 is fixed at the top center of each screen 4, surrounding the stirring shaft 2. The inner diameter of the fixing ring 5 matches the outer diameter of the stirring shaft 2, and the two are fixed by welding. A spring 6 is fixed between the inner side of the fixing ring 5 and the stirring shaft 2, with the other end also fixed to the stirring shaft 2. During operation, the spring 6, depending on the working requirements and the state of the materials, may be in a stretched or compressed state, providing elasticity to the screens 4. The bottom of each screen 4 is fixed by welding. An arc-shaped ring 7 is integral with the screen 4. The surface of the arc-shaped ring 7 has a notch 8, one end of which is rounded 9. A fixing plate 10 is installed on the stirring shaft 2 at a position corresponding to the arc-shaped ring 7. The surface of the fixing plate 10 fits against the surface of the arc-shaped ring 7. During operation, the two work together during the rotation of the stirring shaft 2, affecting the movement of the screen 4. The stirring assembly 11, according to its structural design, is welded onto the stirring shaft 2. When the stirring shaft 2 rotates, the stirring assembly 11 rotates synchronously, feeding the material into the reaction vessel 1. The stirring operation promotes the mixing and reaction of materials, meeting the requirements of the production process for material handling. The feed port 12 is located on the side of the reactor 1. The feed port 12 serves as a channel for materials to enter the reactor 1, introducing raw materials into the reactor to provide material conditions for subsequent chemical reactions. The discharge port 13 is located at the center of the bottom of the reactor 1, facilitating the discharge of materials after the reaction under the action of gravity. A valve 14 is installed inside the discharge port 13. The valve 14 can control the opening and closing state of the discharge port 13 and adjust the material discharge speed according to actual production needs.

[0034] First, refer to Figure 3In this embodiment, a rotating ring 15 is also included. The rotating ring 15 is mounted on the stirring shaft 2 and is fitted onto the outer surface of the stirring shaft 2. It is connected to the stirring shaft 2 via a suitable bearing structure, allowing the rotating ring 15 to rotate around the stirring shaft 2. At the very center of the top of each screen 4, a circular fixing ring 5 is securely connected to the screen 4 via a nut. The fixing ring 5 surrounds the stirring shaft 2, and its inner diameter matches the outer diameter of the stirring shaft 2. The two are connected in a clearance fit. This connection method allows the fixing ring 5 to stably surround the stirring shaft 2 while also providing a certain amount of room for movement. One end of a spring 6 is welded to the inner side of the fixing ring 5, and the other end is welded to the rotating ring 15. In this way, the screen 4 is connected to the rotating ring 15 via the spring 6, changing the original direct connection between the spring 6 and the stirring shaft 2. In terms of position, the rotating ring 15 is located on the outer surface of the stirring shaft 2. The screen 4 is connected to the stirring shaft 2 by the fixed ring 5 at the top and is connected to the rotating ring 15 by the spring 6. This layout provides a specific structural foundation for the operation of the device. In terms of connection, the connection methods such as nuts, welding, and clearance fits ensure the stability of the connection between the various components and the smoothness of operation. In terms of function, the rotating ring 15 rotates around the stirring shaft 2. With the elasticity of the spring 6, the screen 4 will make corresponding movements due to the stretching or compression of the spring 6 during the operation of the device. At the same time, the rotation of the rotating ring 15 will affect the movement and force on the screen 4, which helps the material to be screened or mixed on the screen 4 to meet the different working requirements of the device.

[0035] Then, refer to Figure 7In this embodiment, the stirring assembly 11 consists of multiple double-sided blades 16. Each double-sided blade 16 is perpendicular to the stirring shaft 2 and is evenly distributed at equal intervals along the axial direction of the stirring shaft 2. The double-sided blades 16 are firmly fixed to the outer surface of the stirring shaft 2 by welding, and the screen 4 is located in the space between each double-sided blade 16. Specifically, in the axial dimension of the stirring shaft 2, the area between adjacent double-sided blades 16 accommodates the screen 4. From the positional relationship, the double-sided blades 16 are perpendicular and evenly distributed around the stirring shaft 2, while the screen 4 is interspersed between the double-sided blades 16. The three together constitute the layout structure of the stirring assembly 11 in the reactor 1. In terms of connection, the double-sided blades 16 are tightly connected to the stirring shaft 2 by welding, ensuring that the double-sided blades 16 can stably follow the rotation of the stirring shaft 2 during its rotation. In terms of function, when the stirring shaft 2 starts to rotate, the double-sided blades 16 fixedly connected to it perform a circular motion. The rotation of the double-sided blades 16 applies force to the material inside the reactor 1, propelling it to flow and causing collisions and mixing between particles to achieve thorough mixing. Meanwhile, the screen 4, positioned between the double-sided blades 16, uses its mesh structure to screen and filter the material during mixing, separating particles that do not meet the screen aperture requirements. Simultaneously, the shape and position of the screen 4 guide the flow direction of the material, creating a specific flow path within the reactor 1, further optimizing the uniformity and efficiency of the mixing and meeting the process requirements for material handling within the reactor.

[0036] Secondly, see Figure 4In this embodiment, it also includes at least one chute 17 and a corresponding number of sliders 18. At least one chute 17 is formed inside the reactor 1. In this embodiment, the specific number is preferably set to three. These three chute 17s are distributed along a specific inner wall region inside the reactor 1. The chute 17 has a linear groove-like structure, and its length extends along a specific direction along the inner wall of the reactor 1. The sliders 18 are fixed to the side of the screen 4, specifically, at a position on the side of the screen 4 perpendicular to the stirring shaft 2. The shape of the sliders 18 is specially designed to match the shape of the chute 17. The slider 18 is precisely fitted into the groove 17, allowing it to fit snugly inside. Positionally, the groove 17 is located inside the reactor 1, while the slider 18 is fixed to the side of the screen 4. The two are connected by the slider embedding into the groove 17, establishing a specific positional relationship between the screen 4 and the inner wall of the reactor 1. The position of the screen 4 within the reactor 1 is restricted and guided by the groove 17. In terms of connection, the slider 18 and the groove 17 form a sliding connection. This connection is achieved through the precisely fitted shape of the slider 18 and the groove 17, ensuring that the slider 18 fits snugly within the groove 17. The slider 18 is fixed to the side of the screen 4 by means of welding, bolting, or other specific processes to ensure a stable and reliable connection between the slider 18 and the screen 4 during operation. From a functional perspective, when the stirring shaft 2 rotates, it drives the screen 4 to move. Simultaneously, the extension and contraction of the spring 6 and the force exerted by the material on the screen 4 jointly affect its movement. Under the combined effect of these forces, due to the sliding connection between the slider 18 and the chute 17, the screen 4 can slide along the direction of the chute 17 within the reactor 1. This sliding motion allows the screen 4 to adjust its position more flexibly during material mixing, thus better fulfilling its functions of screening, filtering, and guiding material flow. For example, during material flow, the sliding of the screen 4 can change its contact position and angle with the material, making the screening and filtering effects more uniform and efficient. Furthermore, the sliding of the screen 4 can further guide the material to form a more complex and rational flow path within the reactor 1, promoting thorough mixing and meeting the diverse process requirements of material handling within the reactor.

[0037] Finally, see Figure 7 In this embodiment, a bracket 19 is also included. The bracket 19 is fixed to the top of the reactor 1 and is stably connected to the top of the reactor 1 by welding. A motor 20 is installed on the side of the bracket 19. The output shaft of the motor 20 is directly welded to the stirring shaft 2 to achieve a fixed connection. After the motor 20 is started, the output shaft drives the stirring shaft 2 to rotate, providing power for the movement of the stirring assembly 11 and the screen 4.

[0038] Working principle:

[0039] The feeding device for the production of PVC hollow composite tiles first involves the operator adding solid granular polyvinyl chloride resin raw material into the reactor 1 through the feed inlet 12 in a predetermined amount. The motor 20, mounted on the side of the support 19, is then started. The output shaft of the motor 20 drives the stirring shaft 2, which is welded to it, to rotate. The rotation of the stirring shaft 2 drives the double-sided blades 16 mounted on it to stir the raw material in the reactor 1. When there are uneven particle sizes in the raw material, and larger, unmelted particles are stuck on the screen 4, the screen 4 is connected to the rotating ring 15 on the stirring shaft 2 via a spring 6. The slider 18 on the side of the screen 4 can slide in the groove 17 inside the reactor 1. When the stirring shaft 2 rotates, it drives the clamping plate 10 to rotate. The clamping plate 10 engages with the arc-shaped ring 7, causing the screen 4 to move. Simultaneously, the spring 6 contracts. When the clamping plate 10 moves to the notch 8 position, the elastic potential energy of the spring 6 causes the screen 4 to reset, generating vibration.

[0040] After being heated and stirred, the raw materials are discharged from the reactor 1 by opening the valve 14 inside the discharge port 13.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
