Description

Technical Field

[0001] The invention relates to the technical field of foam board production, and in particular to a foam board production device. Background Art

[0002] Foam board, also known as Chevron board or Andy board, its chemical composition is mainly polyvinyl chloride (PVC), so it is also called foam polyvinyl chloride board. It has the characteristics of light weight, waterproof, flame retardant, acid and alkali resistance, moth-proof, heat preservation, sound insulation, shock absorption, etc. At the same time, it is also a non-toxic, odorless, pollution-free environmentally friendly material, widely used in construction, advertising, packaging and other fields.

[0003] The current foam board production process includes: raw material preparation, high-speed mixing, low-speed cold mixing, conical twin-screw extrusion, die shaping (skin foaming), cooling and shaping, multi-roller traction, product cutting, collection and inspection.

[0004] During the cutting process of the foam board, due to the influence of extrusion, foaming and other processes, the heat distribution inside the board may not be uniform, especially when the board is thicker or the amount of foaming agent used is larger, the heat inside the board may be higher and the distribution is more uneven. When the foam board is cut, the part that was originally "supported" by the heat inside the board is removed, causing the heat to be more easily transferred to both sides. At this time, the heat inside the board is still high, and the material strength of the edge part is not enough to resist the influence of heat, the edge will expand, affecting the production quality of the foam board.

[0005] In the prior art, a cutting device (Announcement No.: CN209579679U) is disclosed. Although the cutting device places a PVC foam board on a cutting table, and then controls motor one and motor two to adjust the position of the cutting motor installed on the lead screw according to the size of the waste edges on both sides of the PVC foam board, so that the cutting blades on the cutting motor correspond to the positions of the waste edges required to be cut on both sides of the PVC foam board and are accurately positioned by an infrared device, the waste edges on both sides of the PVC foam board can be cut at the same time, saving cutting time and improving cutting efficiency. However, in actual use, after the cutting is completed, the edge of the foam board is not promptly processed and protected, and the edge of the foam board is easily affected by the central heat and expands and deforms.

After reaching a certain temperature, the cooling effect of the water flow on the foaming plate can be ensured by changing the water flow. The water pump 19 is installed on the water tank 18. The water flow in the water tank 18 can be transported to the water guide cavity 17 through the water pump 19 to cool the heat-conducting frame 12, the lifting plate 13 and the ball 16. A water delivery pipe 1 is installed on the water pump 19. The water delivery pipe 1 is set with a three-way pipe. The other two ends of the water delivery pipe 1 are respectively connected to the heat-conducting frame 12 and the lifting plate One end of the water guide cavity 17 on the heat conducting frame 12 and the lifting plate 13 is connected, and the water flowing into the water guide cavity 17 can flow back into the water tank 18 through the pipeline to form a water circulation. A water delivery pipe 2 is installed on the water tank 18. The water delivery pipe 2 adopts a three-way pipeline setting. The other two ends of the water delivery pipe 2 are respectively connected with one end of the water guide cavity 17 on the heat conducting frame 12 and the lifting plate 13. The heat conducting frame 12 and the lifting plate 13 are both equipped with convex strips, and one side of the convex strips extends to the central axis position of the ball 16, which is used to limit the edge of the foaming plate to ensure that the ball 16 can stably contact the edge of the foaming plate.

The heat-conducting frame 12 is provided with a plurality of long through grooves, and the plurality of long through grooves are all connected to the air delivery cavity 26. When the foaming plate moves, the air pump 20 is used to extract the heat-collecting air inside the heat-conducting frame (12). At the same time, by setting the absorption airflow, a low-temperature area can be formed on one side of the edge of the foaming plate, thereby accelerating the rate at which the heat in the middle of the foaming plate flows to both sides. A filter plate is installed in the long through groove to prevent dust from entering the air delivery cavity 26.

[0024] like Figure 4 and Figure 6 As shown, a support frame 24 is installed on the fixed frame 11, and a pushing cylinder three 25 is installed on the support frame 24. An air guide frame 22 is arranged above the conveying part 3, and the air guide frame 22 is connected to the telescopic shaft of the pushing cylinder three 25.

[0026] In this embodiment, the pipe used is selected as a soft pipe or a hard pipe according to actual usage conditions to avoid affecting the movement of the object.

[0027] In this embodiment, the foaming board is moved by a multi-roller traction device outside; When in use, the position of the cutting knife 7 is adjusted according to the production requirements of the foam board. First, the positions of the multiple cutting knives 7 in the same cutting box 5 are adjusted according to the width of the waste after the foam board is cut. The operation is as follows: the adjusting screw 8 is turned to adjust the position of the moving frame 6, thereby completing the position adjustment of the cutting knife 7, so that multiple cuts are arranged in a ladder shape, and the foam board is cut evenly. Then, the positions of the two cutting boxes 5 are adjusted by the screw moving component 4, thereby adjusting the position between the cutting knives 7 located in the two cutting boxes 5, so that the distance between the two cutting knives 7 located at the last cutting is the same as the distance required for the production of the foam board. Then, the foam board is moved by pulling the multi-roller pulling device, and the cutting operation of the foam board can be completed by the cutting knife 7; After the cutting of both sides of the foaming board is completed, it will continue to move to the conveying part 3. During the movement of the foaming board in the conveying part 3, the position between the two heat-conducting frames 12 can be adjusted by the two pushing cylinders 14, and the position of the lifting plate 13 can be adjusted by the pushing cylinder 2 15 at the same time, and the contact between the ball bearing 16 and the edge of the foaming board is adjusted. Then, the water pump 19 is started to convey water to the water guide cavity 17. The heat flowing out of the foaming board can be transferred to the heat-conducting frame 12 and the lifting plate 13 through the contact between the ball bearing 16 and the foaming board. The heat-conducting frame 12 and the lifting plate 13 are cooled by the flow of water in the water guide cavity 17, thereby contact cooling of the edge of the foaming board can be performed; Start the vacuum pump 20, the air flow flows into the air delivery cavity 26 through the long through groove, and then flows into the vacuum pump 20 through the air guide pipe. In this process, the heat flowing out from the edge of the foam board will flow with the air flow, thereby increasing the cooling effect on the edge of the foam board. At the same time, the air flow can form a low-temperature area on one side of the edge of the foam board, thereby accelerating the rate at which the heat in the middle of the foam board flows to both sides, which can improve the cooling efficiency of the foam board. The air flow absorbed by the vacuum pump 20 will flow into the air guide frame 22 through the air delivery pipe 21, and then act on the surface of the foam board through the air outlet 23. The air flow acting on the surface of the foam board contains part of the heat flowing out of the foam board. This heat acting on the surface of the foam board can make the heat on the surface of the foam board reach a relatively uniform state, thereby avoiding uneven heat on the foam board during the flow process, which causes wrinkles on the surface of the foam board, and ensuring the production quality of the foam board.

[0028] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
