Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, in particular to a reaction chamber structure of a coating machine. Background Art

[0002] The coating machine is used to adsorb the film to the surface of the product to form a coating. The film can be heated and then covered on the product by air pressure difference. When coating the product, the film is first transported to the top of the product, and then the film is covered on the product by closing the mold. The traditional coating process is to close the mold, evacuate and heat the mold cavity, and the neutrons will lift the product. At this time, the product will partially contact the film, and then the mold cavity will be filled with high pressure. The edge of the product that first contacts the film will form an imprint. After the coating or transfer is completed, the high-pressure gas is discharged, and the mold is opened to take out the product. When coating, when using some films with straight lines or flash point lines for product coating or transfer, because the film is secondary molded and stretched, the outer part of the film that first contacts the product will produce lines or marks after the product is filled with high pressure. Utility Model Content

[0003] The utility model aims to provide a reaction chamber structure of a coating machine. When the neutrons rise to push the product to fit the diaphragm, the neutrons push the product up and at the same time, the elastic support frame structure pushes the diaphragm open, so that the diaphragm does not contact part of the periphery of the product first. The product rises and fits the diaphragm under the continued push of the neutrons, and the diaphragm does not produce lines or marks on part of the periphery of the product.

[0004] To achieve the above-mentioned purpose, the technical solution provided by the utility model is: a reaction chamber structure of a coating machine, including a reaction chamber, in which an upper mold and a lower mold are arranged, and the membrane used for coating is sealed and positioned by the upper mold and the lower mold, and the lower mold is provided with a lifting bracket for placing the product, and the lifting bracket is also provided with an elastic support frame structure for elastically supporting the membrane.

[0005] The utility model adopts the above-mentioned technical scheme, and the diaphragm is first arranged on the lower mold. When the lower mold moves toward the upper mold to close the mold, the diaphragm is tightly attached to the bottom of the upper mold and a coating chamber is formed in the space enclosed by the diaphragm and the upper mold by vacuuming. During the continuous rising process of the lifting bracket, the elastic support frame structure pushes open the diaphragm, so that the diaphragm does not contact the outer part of the product. After the lifting bracket rises to its position, high pressure is applied in the coating chamber enclosed by the diaphragm and the upper mold, so that the diaphragm is pressed down by the high-pressure gas, and the product located in the area of ​​the elastic support frame structure continues to rise and contacts the diaphragm for coating. The outer part of the product does not contact the outer part because the diaphragm is supported by the elastic support frame structure, and no lines or marks are produced.

[0006] For the reaction chamber structure of the above-mentioned coating machine, the elastic support frame structure includes a spring, a fixing piece and a retaining piece fixed at both ends of the spring. The spring is fixed on the neutron through the fixing piece, and the retaining piece is arranged at the top of the spring. The fixing piece can fix the spring by screwing, and the retaining piece is arranged at the top of the spring, which can increase the contact area with the diaphragm and better expand the diaphragm.

[0007] For the reaction chamber structure of the above-mentioned coating machine, the lifting support includes a neutron and a lifting rod. The lifting rod is movably inserted through the bottom of the reaction chamber to drive the neutron to lift. The lifting rod is used to connect the cylinder, so as to drive the neutron to lift by the cylinder.

[0008] For the reaction chamber structure of the above-mentioned coating machine, a guide rod is connected to the bottom of the neutron, and the guide rod is movably inserted through the bottom of the reaction chamber. The guide rod plays a guiding role to make the lifting movement of the neutron stable.

[0009] For the reaction chamber structure of the above-mentioned coating machine, the lifting support includes a supporting plate and a lifting cylinder. The supporting plate places the product, and the lifting cylinder is arranged at the bottom of the reaction chamber to drive the supporting plate to lift.

[0010] For the reaction chamber structure of the above-mentioned coating machine, the upper mold includes an upper template and an upper mold housing. The upper template is arranged at the bottom of the upper mold housing. The lower mold includes a lower template. Through holes are provided in the middle of the lower template and the upper template. The lower template and the upper template are attached to clamp the diaphragm. After the lower mold and the upper mold are closed, the lower template and the upper template are attached and clamp the diaphragm. The through hole on the lower template can accommodate the elastic support frame structure to push up and expand the diaphragm when the neutron rises. After the diaphragm is expanded and its height rises, the supporting plate can continue to rise to make the product contact the diaphragm.

[0011] For the reaction chamber structure of the above-mentioned coating machine, a sealing ring is provided between the upper template and the lower template. The upper template and the lower template are sealed after closing through the sealing ring.

[0012] For the reaction chamber structure of the above-mentioned coating machine, a driving rod for driving the lower template to lift is connected to the bottom of the lower template. The driving rod drives the lower template to lift to realize closing and opening of the mold.

[0013] For the reaction chamber structure of the above-mentioned coating machine, an air extraction port for vacuum extraction communicating with the inner cavity of the upper mold is provided on the side wall of the reaction chamber.

DETAILED DESCRIPTION

[0027] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0028] Reference Figures 1 to 10 A reaction chamber structure of a coating machine includes a reaction chamber 1, in which an upper mold 2 and a lower mold 3 are arranged. A membrane 4 for coating is sealed and positioned by the upper mold 2 and the lower mold 3. The lower mold 3 is provided with a lifting bracket 3a for placing a product 5. The lifting bracket 3a is also provided with an elastic support frame structure 32 for elastically supporting the membrane 4.

[0029] Among them, the diaphragm 4 can be placed on the lower mold 3 in advance, and when the lower mold 3 moves upward to close the mold with the upper mold 2, the diaphragm 4 is clamped; the lower mold 3 is provided with a lifting bracket 3a for placing the product 5, and an elastic support frame structure 31 is arranged around the product, and the elastic support frame structure 32 is distributed on the periphery of the product 5, and the product 5 is located in the area of ​​the elastic support frame structure 32. In this embodiment, the elastic support frame structure 32 can be set to 4. In other embodiments, the elastic support frame structure 32 can be set to a number that is suitable for supporting the diaphragm 4 without contacting the outer edge of the product 5; when the lower mold 3 and the upper mold 2 are closed, the diaphragm 4 fits the inner cavity of the upper mold 1, and then the space enclosed by the upper mold 1 and the diaphragm 4 is formed into a coating chamber 20 by vacuuming. After the vacuum is drawn, the lifting bracket 3a rises and opens the diaphragm 4 through the elastic support frame structure 32. After the diaphragm 4 is opened, high-pressure gas is input into the coating chamber 20 to fill the coating chamber 20 with high pressure, press the diaphragm 4 downward, and press the elastic elastic support frame structure 31 downward at the same time, and then continue to lift the product 5 to make it contact the diaphragm 4; after the elastic support frame structure 31 pushes the diaphragm 4 open so that it does not contact the edge of the product, the product 5 located in the area of ​​the elastic support frame structure 31 rises and contacts the diaphragm 4. Among them, a mechanism for pushing the product 5 up can be independently set up. For example, the product is placed on a plate that can move on the neutron 31, such as a supporting plate. The supporting plate is pushed up by a cylinder to drive the product 5 to rise and contact the diaphragm 4 to achieve coating.

[0030] In this embodiment, if Figure 10 As shown, the elastic support frame structure 32 includes a spring 321 and a fixing sheet 322 and a baffle 323 fixed at both ends of the spring 321. The spring 321 is fixed to the neutron 31 through the fixing sheet 322, and the baffle 323 is arranged at the top of the spring 321. The fixing sheet 322 and the baffle 323 are fixedly connected at both ends of the spring 321. The spring 321 is fixed to the neutron 31 through the fixing sheet 322. When the spring 321 contacts the diaphragm 4, it contacts the diaphragm 4 through the baffle 323, and pushes the diaphragm 4 open during the rise. The spring 321 plays a buffering role.

[0031] like Figure 1 , Figure 6As shown, the lifting bracket 3a includes a neutron 31 and a lifting rod 311. The lifting rod 311 is movably inserted through the bottom of the reaction chamber 1 to drive the lifting of the neutron 31. The lifting rod 311 can be connected to a driving component that drives its lifting movement, such as a cylinder, an oil cylinder, a linear motor, etc.

[0032] A guiding rod 11 is connected to the bottom of the neutron 31. The guiding rod 11 is movably inserted through the bottom of the reaction chamber 1. The guiding rod 11 plays a role in guiding the lifting movement of the neutron 31.

[0033] Such as Figure 2 , Figure 4 and Figure 5 As shown, the lifting bracket 3a includes a supporting plate 33 and a lifting cylinder 313. The supporting plate 33 places the product 5. The lifting cylinder 313 is arranged at the bottom of the reaction chamber 1 to drive the lifting of the supporting plate 33. Among them, the piston rod of the lifting cylinder 331 is connected to the supporting plate 33 through a straight rod 14. By driving the lifting movement of the supporting plate 33 through the lifting cylinder 33, the product 5 contacts the diaphragm 4.

[0034] Such as Figure 6 , Figure 7 As described, the upper die 2 includes an upper template 21 and an upper die housing 22. The upper template 21 is arranged at the bottom of the upper die housing 22. The lower die 3 includes a lower template 34. Through holes 6 are provided in the middle of the lower template 34 and the upper template 21. The lower template 34 and the upper template 21 are attached to clamp the diaphragm 4. During implementation, the diaphragm 4 can be pre-placed on the lower template 34. After the lower template 34 moves upward towards the upper template 21 to close the die, the upper template 21 and the lower template 34 clamp the diaphragm 4. Among them, a sealing ring 7 is provided between the upper template 21 and the lower template 34.

[0035] In this embodiment, a driving rod 12 that drives the lifting of the lower template 34 is connected to the bottom of the lower template 34. An air extraction port 13 for evacuating the inner cavity of the upper die 2 is provided on the side wall of the reaction chamber 1. A heating device 23 is provided on the inner top wall of the upper die housing 22.

[0036] Such as Figures 1 - 10 As shown, the diaphragm 4 is placed on the lower template 34. During the film covering operation, the lower template 34 moves towards the upper template 21 through the driving rod 12 until the lower template 34 is attached to and clamps the diaphragm 4 to complete the die closing. After the die closing, the film covering chamber 20 is evacuated through a suction fan or an air pump to form a vacuum chamber in the film covering chamber 20. Initially, the neutron 31 is in the lowest position, such as Figure 2 As shown. The neutron 31 is driven to move upward through the lifting rod 311, driving the supporting plate 33 and the product 5 arranged on the neutron 31 to rise. As the neutron 31 rises, the elastic support frame structure 32 contacts the diaphragm 4, such as Figure 4As shown, the neutron 31 continues to rise. When the neutron 31 rises to the right position, the elastic support frame structure 32 pushes the diaphragm 4, so that the diaphragm 4 is stretched upward, and the product 5 is located below the stretched part of the diaphragm 4. Figure 5 As shown. Then, high-pressure gas is filled into the film-coating chamber 20 to form a high-pressure cavity in the film-coating chamber 20. At this time, the lifting cylinder 331 pushes the straight rod 14 to control the support plate 33 to rise upward, so that the product 5 contacts the diaphragm 4. After the product contacts the diaphragm 4, the heating effect is achieved through the heating device 23, and the exhaust port 13 is connected to the exhaust fan or air pump to evacuate the interior of the upper mold shell 22 to form the film-coating chamber 20. Then, high-pressure gas is input to form a high-pressure cavity in the film-coating chamber 20. The diaphragm 4 is covered on the product 5 to complete the film coating.

[0037] Among them, the lower template 34 matches the shape of the upper template 21, and a through hole 6 is set in the middle, so that after the lower template 34 and the upper template 21 are molded together, the neutron 31 can drive the elastic support frame structure 32 to lift the diaphragm 4 upward, and the supporting plate 33 can drive the product 5 to move upward and contact the diaphragm 4.
