Description

Technical Field

[0001] This invention belongs to the field of polymer material heating technology, specifically relating to a polymer material heating and pressing device. Background Technology

[0002] The polymer material heating and pressing device mainly uses heating and pressure to cause the polymer material to undergo plastic deformation under specific temperature and pressure, thereby pressing it into sheets of the required shape and size.

[0003] Current polymer material heating tableting equipment, with its built-in high-efficiency heating mechanism, can effectively heat-treat polymer materials during the processing, laying a solid foundation for subsequent tableting operations. However, in this series of precise and complex operations, the tableting equipment often releases a large amount of heat. If workers are accidentally exposed to this high heat, it could potentially cause burns and other safety hazards, posing a serious threat to the health of the operators. Furthermore, existing heating and pressing devices also have certain limitations in the heating process. Specifically, when starting the heating program, the equipment adopts a method of uniformly heating the entire pressing surface. While this method ensures heating uniformity to some extent, it undoubtedly prolongs the heating time, thus affecting the efficiency of the entire production process. This slow heating not only increases energy consumption but also, to some extent, restricts the speed and quality of polymer material processing. Summary of the Invention

[0004] The purpose of this invention is to provide a polymer material heating and pressing device to solve the problems of safety hazards and low processing efficiency of existing heating and pressing devices mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a polymer material heating and pressing device, comprising a base with a placement mold mounted on the top; an upper plate positioned directly above the base, with guide posts mounted at the four corners of both; a pressing mold also positioned at the bottom of the upper plate; and a stud penetrating the upper plate and threadedly connected thereto, the bottom end of which is connected to the pressing mold. During processing, the polymer material is wrapped in tin foil and placed on the placement mold. The stud is then rotated, causing the pressing mold to move downwards until it is pressed against the placement mold. At this point, an external control device is activated to adjust the heating elements inside the pressing mold and placement mold, thereby processing the polymer material. The stud and the mold should be in a rotating abutting state, that is, the stud is movably connected to the mold in the axial direction, while being limited by the mold in the vertical direction. Since this structure is existing technology, it will not be described in detail here. It also includes a protective component, which is set on the mold and the placement mold. The protective component separates the heat on the mold and the placement mold to prevent heat from being conducted to the outermost surface and causing burns. The heating component is placed at the internal center of the mold and the placement mold. The vertical projection of the heating component inside the mold and the placement mold coincides. The heating component extends outward of the mold and the placement mold in a planar spiral manner, thereby realizing the rapid heating and processing of polymer materials.

[0006] As a preferred technical solution of the present invention, the top of the placement mold is provided with a surface groove, the heating component includes a heating wire placed on the bottom surface of the surface groove, and a placement plate is also placed inside the surface groove. The placement plate covers the heating wire. In the heating of the polymer material, the heating wire in the disc is used to achieve rapid heating and conduct the temperature to the area of ​​the placement plate, avoiding the temperature from being transmitted to the side of the placement mold.

[0007] As a preferred technical solution of the present invention, the bottom end face of the placement plate is provided with a coil groove for placing the heating wire, and a lifting rod is also installed on the side of the heating wire. The entire heating wire can be easily removed by the lifting rod. The bottom end face of the placement plate is also provided with a slot for placing the lifting rod.

[0008] As a preferred technical solution of the present invention, the protective component is the distance between the placement plate and the inner wall of the placement mold. This distance is a partition groove, and the depth of the partition groove is greater than the depth of the surface groove, thereby ensuring temperature separation.

[0009] As a preferred technical solution of the present invention, a sealing strip is embedded inside the opening of the partition groove near the edge of the two parts. The sealing strip seals the gap formed by the partition groove. The height of the sealing strip is less than the depth of the partition groove, thereby achieving heat separation through the cavity formed by the partition groove. The sealing strip is made of polypropylene, which has the characteristics of high temperature resistance.

[0010] As a preferred technical solution of the present invention, pipes with one-way valves are installed on the surfaces of the pressing mold and the placement mold. The end of the pipe with the one-way valve is connected to the cavity inside the partition groove, and the other end of the pipe with the one-way valve is connected to an external vacuum pump. By extracting the gas in the cavity formed by the partition groove and the sealing strip, the heat insulation effect can be improved and better protection can be achieved.

[0011] As a preferred technical solution of the present invention, the stud is threadedly connected to the upper plate, and a handwheel is also installed on the top of the stud, which allows the stud to be rotated conveniently and quickly.

[0012] As a preferred technical solution of the present invention, both the pressing mold and the placement mold are connected to a transmission harness, which passes through the protective component and is connected to the heating component inside the pressing mold and the placement mold.

[0013] Compared with the prior art, the beneficial effects of the present invention are: In this invention, the protective component effectively isolates the heat released by the pressing mold to the outside during operation, fundamentally avoiding the risk of burns to workers due to accidental contact with the high-temperature pressing mold, and significantly improving the safety of the entire operating environment. At the same time, in the design of the heating area, by optimizing the layout of the heating elements, the heating area is precisely concentrated in the pressing area of ​​the polymer material. This change not only allows the heat to act on the material more directly and effectively, thereby greatly improving the efficiency of heating and pressing, but also significantly reduces the unnecessary conduction of heat to the outer surface of the pressing mold. While reducing energy consumption, it can also further improve safety and overcome the shortcomings of existing heating and pressing devices in use. Attached Figure Description
