Description

Technical Field

[0001] This utility model relates to the field of extrusion equipment technology, and in particular to a high-efficiency extrusion equipment for PVC floating boards. Background Technology

[0002] PVC floating boards are lightweight boards made from polyvinyl chloride as the main raw material. They have good buoyancy and corrosion resistance and are often used in hydroponics, construction of aquatic facilities, etc., to provide support and basic structure for related scenarios.

[0003] PVC floats are widely used in hydroponics, water recreation facilities, and other fields. They require high-efficiency extrusion equipment for precise molding and mass production. High-efficiency extrusion equipment for PVC floats utilizes an optimized screw structure to enhance plasticization. Combined with an intelligent temperature and pressure control system, it can ensure uniform plasticization of materials and stable extrusion, thereby improving product quality and production efficiency.

[0004] However, existing high-efficiency extrusion equipment for PVC floating boards has the following shortcomings:

[0005] In the existing technology, the high-efficiency extrusion equipment for PVC floats requires the raw materials to be fed into the screw barrel. However, due to differences in production processes or improper storage, some large particles may be present in the raw materials. These large particles are difficult to disperse evenly during screw conveying and plasticizing, resulting in uneven plasticizing of the material. This leads to internal defects in the extruded PVC floats, such as bubbles and uneven density, which seriously affects the product quality and performance.

[0006] Therefore, we propose a high-efficiency extrusion device for PVC floating boards to solve the problems mentioned above. Utility Model Content

[0007] The purpose of this invention is to provide a high-efficiency extrusion device for PVC floating boards. By using a motor-driven transmission mechanism combined with an eccentric component, the screen assembly can be made to perform efficient reciprocating motion. At the same time, through the coordinated operation of the guide plate and the sliding component, large particles of material can be collected in a concentrated manner, thereby solving the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency extrusion device for PVC floating boards, comprising a screw extruder, wherein a hopper is fixedly connected to the top of the screw extruder, two fixed rods are fixedly connected to the inner wall of the hopper, a sliding frame is movably sleeved between the outer walls of the two fixed rods, a screen is fixedly connected to the outer wall of the sliding frame, a fixed seat is fixedly connected to one side of the outer wall of the sliding frame, a linkage rod is movably sleeved on the outer wall of the fixed seat, a connecting rod is movably inserted into the inner wall of the linkage rod, a rotating disk is fixedly connected to one side of the outer wall of the connecting rod, a drive motor is fixedly inserted into the inner wall of the rotating disk, and a guide plate is fixedly connected to the inner wall of the hopper.

[0009] Preferably, a discharge box is fixedly connected to one side of the outer wall of the hopper, and two sliding grooves are formed on one side of the outer wall of the discharge box.

[0010] Preferably, a sliding cabinet is slidably embedded between the inner walls of the two sliding grooves, and a handle is fixedly connected to one side of the outer wall of the sliding cabinet.

[0011] Preferably, the top of the hopper is fixedly connected to a discharge pipe, and the input end of the discharge pipe is fixedly connected to a conveying pipe.

[0012] Preferably, the top of the conveying pipe is fixedly connected to a feed hopper, and two bearings are fixedly inserted into the inner wall of the conveying pipe.

[0013] Preferably, a rotating shaft is fixedly inserted between the interiors of the two bearings, and a helical blade is fixedly sleeved on the outer wall of the rotating shaft.

[0014] Preferably, a conveyor motor is fixedly connected to one side of the outer wall of the rotating shaft.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, through the interaction of the various components of the device, the transmission mechanism of the motor drive combined with the eccentric component can promote the efficient reciprocating motion of the screen component. At the same time, through the coordinated operation of the guide plate and the sliding component, large particles of material can be collected. In this way, the raw materials are accurately screened, effectively preventing large particles of raw materials from entering the screw conveying and plasticizing process. Since large particles of material are screened out in advance, the material can be evenly dispersed during the screw conveying and plasticizing process, eliminating the problem of internal defects in the extruded PVC float due to uneven plasticizing of the material, and effectively ensuring the quality and performance of the product.

[0017] 2. In this utility model, the uniform conveying of raw materials is achieved through the interaction of the various components of the device, which can effectively alleviate the instantaneous material load on the screening component and avoid excessive impact force of feeding. At the same time, this method can complete the feeding process with low human intervention, which significantly reduces the labor intensity of manual feeding. Attached Figure Description

Detailed Implementation

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, as shown in the attached document Figure 1 - Appendix Figure 4As shown, this utility model provides a technical solution: a high-efficiency extrusion device for PVC floating boards, including a screw extruder 1, a hopper 2 fixedly connected to the top of the screw extruder 1, two fixed rods 3 fixedly connected to the inner wall of the hopper 2, a sliding frame 4 movably sleeved between the outer walls of the two fixed rods 3, a screen 5 fixedly connected to the outer wall of the sliding frame 4, a fixed seat 6 fixedly connected to one side of the outer wall of the sliding frame 4, a linkage rod 7 movably sleeved on the outer wall of the fixed seat 6, a connecting rod 8 movably inserted into the inner wall of the linkage rod 7, a rotating disk 9 fixedly connected to one side of the outer wall of the connecting rod 8, a drive motor 10 fixedly inserted into the inner wall of the rotating disk 9, a guide plate 11 fixedly connected to the inner wall of the hopper 2, a discharge box 12 fixedly connected to one side of the outer wall of the hopper 2, two sliding grooves 13 opened on one side of the outer wall of the discharge box 12, a sliding cabinet 14 slidably embedded between the inner walls of the two sliding grooves 13, and a handle 15 fixedly connected to one side of the outer wall of the sliding cabinet 14.

[0026] The effect achieved by the entire embodiment 1 is as follows: After the raw materials enter the hopper 2 through the conveying component, they will first fall to the top of the screen 5. The screen 5 screens the raw materials according to the preset aperture specifications. Materials with the required particle size can pass through smoothly, while large particles are intercepted. At the same time, the drive motor 10 is started, and its output end drives the rotating disk 9 to rotate. Since the connecting rod 8 is fixedly connected to one side of the outer wall of the rotating disk 9, and the connecting rod 7 is movably sleeved on the outer wall of the connecting rod 8, the circular motion of the rotating disk 9 is converted into the reciprocating linear motion of the connecting rod 7. The connecting rod 7 then drives the sliding frame 4 and the screen 5 to reciprocate together through the fixed seat 6, so that the raw materials at the top of the screen 5 are evenly dispersed and constantly jumping, effectively enhancing the screening efficiency. Large particles will slide down the inclined surface of the screen 5 and finally slide down the inclined surface of the guide plate 11 into the sliding cabinet 14. By pulling the handle 15, the sliding cabinet 14 can be pulled out from the discharge box 12, thereby realizing the centralized collection and cleaning of large particles.

[0027] Example 2, as Figure 2-4 As shown, the top of the feeding hopper 2 is fixedly connected to the feeding pipe 16, the input end of the feeding pipe 16 is fixedly connected to the conveying pipe 17, the top of the conveying pipe 17 is fixedly connected to the feeding hopper 18, two bearings 19 are fixedly inserted into the inner wall of the conveying pipe 17, a rotating shaft 20 is fixedly inserted between the interior of the two bearings 19, a spiral blade 21 is fixedly sleeved on the outer wall of the rotating shaft 20, and a conveying motor 22 is fixedly connected to one side of the outer wall of the rotating shaft 20.

[0028] The effect achieved by the entire embodiment 2 is as follows: During use, the operator first feeds the raw materials into the conveying pipe 17 through the feed hopper 18, and then starts the conveying motor 22. The output end of the motor drives the rotating shaft 20 and the spiral blade 21 to rotate synchronously. When the spiral blade 21 rotates, it pushes the material in a spiral propulsion manner, causing it to move upward along the inclined pipe of the conveying pipe 17, and fall into the feed hopper 2 at a uniform speed through the discharge pipe 16 for subsequent screening. This conveying method not only ensures that the material enters the screening component evenly and stably, effectively reducing the material pressure borne by the screening component at the moment, and avoiding the reduction of screening efficiency or equipment damage due to excessive feeding impact, but also completes the feeding operation with a low degree of human intervention, greatly reducing the labor intensity of manual feeding.

[0029] The working principle of the entire equipment is as follows: During operation, the operator first feeds the raw materials into the conveying pipe 17 through the feed hopper 18, then starts the conveying motor 22. The output of the conveying motor 22 drives the rotating shaft 20 to rotate, which in turn causes the spiral blades 21 connected to the rotating shaft 20 to rotate synchronously. During rotation, the spiral blades 21 utilize their unique spiral structure to generate axial thrust, pushing the material upwards along the inclined pipe of the conveying pipe 17. The material is conveyed in an orderly manner during this process, and finally enters the feeding hopper 2 at a uniform speed through the discharge pipe 16. The raw materials entering the feeding hopper 2 first reach the top of the screen 5. The screen 5 precisely screens the raw materials according to the pre-set screen aperture size specifications. Materials with particle sizes that meet the screen aperture size requirements can pass smoothly through the screen 5 and enter the subsequent processing flow, while materials with larger particle sizes that exceed the screen aperture size are intercepted by the screen 5. At the same time, the operator starts the drive motor 10, and the output of the drive motor 10 drives the rotating disk 9 to rotate in a circular motion. Since a connecting rod 8 is fixedly connected to one side of the outer wall of the rotating disk 9, and a linkage rod 7 is movably sleeved on the outer wall of the connecting rod 8, the rotational motion of the rotating disk 9 is converted into the reciprocating motion of the linkage rod 7. The linkage rod 7 then drives the sliding frame 4 and the screen 5 to reciprocate through the fixed seat 6. The reciprocating motion of the screen 5 has multiple functions. On the one hand, it can drive the raw materials at the top of the screen 5 to be evenly dispersed, avoid material accumulation, and make the material fully contact the screen 5. On the other hand, it causes the material to jump continuously on the screen 5. This dynamic motion greatly enhances the screening efficiency. During the screening process, the intercepted large particles will slide down the inclined surface of the screen 5 under their own gravity and the vibration generated by the reciprocating motion of the screen 5. Finally, the large particles are guided by the inclined surface of the guide plate 11 and smoothly enter the interior of the sliding cabinet 14. The operator only needs to pull the handle 15 to pull the sliding cabinet 14 out of the discharge box 12, thereby realizing convenient cleaning and centralized processing of large particles.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
