Description

Technical Field

[0001] This utility model relates to the field of PVC decorative panel technology, and in particular to a production device that can improve the weather resistance of PVC decorative panels. Background Technology

[0002] PVC decorative panels are a type of plastic decorative material made primarily of polyvinyl chloride (PVC). They are lightweight, heat-insulating, moisture-proof, and flame-retardant, and are widely used for interior wall and ceiling decoration. With their smooth surface, rich colors, diverse patterns, and convenient installation, they are one of the most widely used categories of building decoration materials.

[0003] The production of PVC decorative panels requires adding various raw materials into a mixing drum and mixing them thoroughly by a stirring mechanism. However, the existing stirring mechanism does not stir the various raw materials in the drum from top to bottom, resulting in uneven mixing of the raw materials and affecting product quality. Utility Model Content

[0004] The purpose of this invention is to provide a production device that can improve the weather resistance of PVC decorative panels, so as to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-9A production device for improving the weather resistance of PVC decorative panels includes a material cylinder 1, a drive motor 2 mounted above the material cylinder 1, a drive shaft 3 fixedly mounted on the output end of the drive motor 2, multiple evenly distributed slots 4 formed on the outer surface of the drive shaft 3, a stirring shaft 5 sleeved on the outer side of the drive shaft 3, multiple evenly distributed clamping plates 6 fixedly mounted on the inner surface of the stirring shaft 5, the clamping plates 6 respectively engaging in the corresponding slots 4, multiple sets of evenly distributed stirring rods 7 fixedly mounted on the outer side of the stirring shaft 5, and multiple supports fixedly mounted on the top side of the stirring shaft 5. A rod 8, multiple support rods 8 are fixedly installed on the side away from the stirring shaft 5 on the inner side of the rotating ring 9. A connecting groove 10 is opened at the bottom of the rotating ring 9. A connecting ring 11 is rotatably installed in the connecting groove 10. Multiple U-shaped limiting plates 12 are fixedly installed on the outer side of the rotating ring 9. The connecting ring 11 is rotatably installed in the U-shaped limiting plates 12. Multiple push rods 13 are fixedly installed at the bottom of the connecting ring 11. Push rods 14 are fixedly installed at the bottom of the multiple push rods 13 respectively. A cylinder 15 is set below the push rod 14. The telescopic end of the cylinder 15 is fixedly installed at the bottom of the push rod 14.

[0028] In the above embodiment, the drive motor 2 drives the drive shaft 3 to rotate, and the drive shaft 3 drives the stirring shaft 5 to rotate synchronously through the clamping plate 6. The multiple evenly distributed stirring rods 7 on the stirring shaft 5 also rotate accordingly, thereby stirring the various raw materials in the material cylinder 1 and mixing them together. At the same time, the cylinder 15 drives the push rod 14, the top rod 13 and the connecting ring 11 to move up and down. The connecting ring 11 drives the stirring rods 7 to move up and down. When the multiple stirring rods 7 move up and down, they can stir the various raw materials in the material cylinder 1, making them more evenly mixed, thereby improving the quality of the product.

[0029] Specifically, the bottom of the material cylinder 1 is open, and two semi-circular discharge baffles 16 are provided at the bottom of the material cylinder 1. An L-shaped moving plate 17 is fixedly installed on one side of the discharge baffle 16. A servo motor 18 and a ball screw 19 are respectively provided on both sides of the material cylinder 1. The threaded rod of the ball screw 19 is fixedly installed on the output end of the servo motor 18. The L-shaped moving plate 17 has a reserved hole, and the nut of the ball screw 19 is fixedly installed in the reserved hole.

[0030] A fixing plate 20 is fixedly sleeved on the outer side of the material cylinder 1. Two sets of limiting plates 21 are fixedly installed at the bottom of the fixing plate 20. The limiting plate 21 has a bearing mounting hole, and a bearing is fixedly installed in the bearing mounting hole. The threaded rod of the ball screw 19 is sleeved in the inner ring of the bearing.

[0031] In the above embodiment, after the various PVC decorative board raw materials in the barrel 1 are mixed, the servo motor 18 is turned on. The servo motor 18 drives the threaded rod of the ball screw 19 to rotate. When the threaded rod rotates, it drives the L-shaped moving plate 17 to move through the nut. The L-shaped moving plate 17 drives the discharge baffle 25 to move, so that the discharge baffle 25 moves out from directly below the barrel 1. Then, the mixed PVC decorative board raw materials in the barrel 1 fall from the bottom of the barrel 1 into the extruder (not shown in the figure) for the next process.

[0032] Specifically, each set of limiting plates 21 has a guide rod 22 fixedly installed on the side that is close to each other, and the L-shaped moving plate 17 has a guide hole, and the guide rod 22 is slidably installed in the guide hole.

[0033] In the above embodiment, by sliding the guide rod 22 in the guide hole, the L-shaped moving plate 17 moves in a straight line along the trajectory of the guide rod 22.

[0034] Specifically, support legs 23 are fixedly installed around the bottom of the fixed plate 20.

[0035] In the above embodiment, the support legs 23 are used to fix and support the bottom perimeter of the fixing plate 20.

[0036] Specifically, a cross-shaped connecting plate 24 is provided above the material cylinder 1, the top of the drive motor 2 is fixedly installed at the bottom center of the cross-shaped connecting plate 24, and L-shaped connecting plates 25 are fixedly installed on the bottom of the four sides of the cross-shaped connecting plate 24 respectively. The other side of the L-shaped connecting plate 25 is fixedly installed on the outer wall of the material cylinder 1.

[0037] In the above embodiments, the servo motor 2 is installed and fixed by the cross-shaped connecting plate 24 and the L-shaped connecting plate 25.

[0038] Working principle: Various raw materials for producing PVC decorative panels are added through the top opening of the material cylinder 1. A certain amount of UV absorber and stabilizer are also added to improve the weather resistance of the PVC decorative panels. The drive motor 2 and cylinder 15 are turned on. The drive motor 2 drives the drive shaft 3 to rotate. The drive shaft 3, through the clamping plate 6, drives the stirring shaft 5 and multiple stirring rods 7 to rotate synchronously. The rotation of the multiple stirring rods 7 stirs the various raw materials in the material cylinder 1, mixing them together. Additionally, the support rod 8, rotating ring 9, and U-shaped limiting plate 1... 2 will also rotate together, and the U-shaped limiting plate 12 will not be blocked by the top rod 13 when rotating. At the same time, the cylinder 15 works to drive the push rod 14, the top rod 13 and the connecting ring 11 to move up and down. The connecting ring 11 drives the U-shaped limiting plate 12, the rotating ring 9, the support rod 8, the stirring shaft 5, the stirring rod 7 and the clamping plate 6 to move up and down. The clamping plate 6 moves up and down along the trajectory of the clamping groove 4. When the multiple stirring rods 7 move up and down, they can stir the various raw materials in the material cylinder 1, making them more evenly mixed, thereby improving the quality of the product.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
