Description

Technical Field

[0001] The utility model relates to the technical field of film forming, in particular to a film forming device for processing vacuum insulation panels. Background Art

[0002] Vacuum Insulation Panel (VIP) is a new type of high-efficiency insulation material. It uses vacuum insulation technology to isolate heat conduction by maximizing the internal vacuum degree, thereby achieving the purpose of heat preservation and energy saving. VIP consists of three parts: core material, gas adsorption material (Getter) and closed gas barrier film (Barrier). The gas adsorption material is used to absorb internal residual gas and released gas to maintain the vacuum degree of VIP. The gas barrier film is made of plastic and wrapped on both sides of the core material to prevent the penetration of air and water vapor, so that a vacuum is formed inside.

[0003] At present, when vacuum insulation panels are produced, the core material is placed between two layers of gas barrier films, and then the edges are sealed by heat sealing technology to form a closed chamber. The shape of the gas barrier film is flat to adapt to the design of the panel.

[0004] In view of the above scheme, when improving the production equipment, in order to limit the position of the core material on the flat air barrier film to prevent it from deviating during heat sealing, a space for accommodating the core material is set on the lower air barrier film so that the core material will not deviate in the space. For this improvement, there is already a corresponding structure, as recorded in Chinese patent publication No. CN117450360A, which accommodates the core material in the bottom shell and sets a barrier film heat-sealed with the shell above the bottom shell, thereby forming a vacuum insulation panel from top to bottom by the barrier film, the core material and the bottom shell; if the bottom shell is used to process the vacuum insulation panel, the position of the bottom shell needs to be positioned, and the core material can only be placed from the upper open end of the bottom shell, resulting in the entire process taking a lot of time to position the bottom shell, and the four sides of the bottom shell are all raised, which also increases the production cost of the bottom shell.

[0005] Therefore, under the condition that the existing technology adopts the bottom shell production, there are still problems such as low processing efficiency of the vacuum insulation panel and increased bottom shell material cost. Utility Model Content

[0006] The main purpose of the utility model is to provide a film forming device for processing vacuum insulation panels, aiming to improve the processing efficiency of vacuum insulation panels and also reduce the cost of bottom shell materials.

[0007] In order to achieve the above-mentioned purpose, the utility model proposes a film forming device for processing vacuum insulation panels, including a base frame, which includes a long strip of transmission pressure plate for conveying air-isolating film; an auxiliary part, which can tension the side of the air-isolating film and move along the transmission direction of the air-isolating film on the base frame; and a stamping part, which is installed on the base frame and can stamp the force-bearing end of the air-isolating film tensioned by the auxiliary part, so that the stamped area forms a continuous cavity that can accommodate the core material.

[0008] Furthermore, the auxiliary component includes a movable plate installed on the base frame, and the movable plate is provided with tensioning parts on both sides of the air barrier film, and the tensioning parts laterally tension the air barrier film.

[0009] Furthermore, the tensioning part includes a film pressing roller arranged on the movable plate, and the film pressing roller presses and tensions the side edge of the gas barrier film.

[0010] Furthermore, the film pressing rollers include an upper pressing roller and a lower pressing roller which are located on both sides of the air barrier film and rotate on the movable plate frame, wherein the upper pressing roller and the lower pressing roller can approach each other.

[0011] Furthermore, the film pressing rollers on both sides can be adjusted in position along the transverse direction of the air barrier film to adapt to air barrier films of different widths.

[0012] Furthermore, a first telescopic cylinder is installed on the movable plate frame, and the first telescopic cylinder drives the upper pressure roller and the lower pressure roller to move toward each other, or drives the upper pressure roller to move toward the lower pressure roller, or drives the lower pressure roller to move toward the upper pressure roller, so as to tension the side of the air barrier film.

[0013] Furthermore, the stamping part includes a bracket installed on the side of the air barrier film away from the transmission pressure plate, and a stamping tool is slidably arranged on the bracket and in a direction perpendicular to the air barrier film. The stamping tool is adapted to the transmission pressure plate and forms a cavity for accommodating the core material between the two air barrier films.

[0014] Furthermore, the cross section of the punch is convex, and the cross section of the transmission plate is concave to match the punch.

[0015] The above technical solution has the following advantages:

[0016] The utility model adopts a transmission pressure plate to transmit the air barrier film, and the two sides of the air barrier film are tensioned by auxiliary parts. The stamping tool punches and forms the tensioned part of the air barrier film so that the air barrier film is between the stamping tool and the transmission pressure plate. The air barrier film after stamping forms a cavity that can accommodate core materials. The cavity is in a continuous through state and can accommodate multiple core materials. The core materials will be transported together with the air barrier film, which greatly improves the transmission efficiency. The lower diaphragm of the vacuum insulation panel only needs to be stamped by the film, and there is no need to place the core material on one side of the bottom shell, thereby greatly improving the placement efficiency of the core material. At the same time, after the film is stamped, only the middle part needs to form a cavity, and the two sides form a table. The two sides of the transmission direction are directly opened, and the open part is convenient for placing the core material, which not only saves the material of the core material but also improves the placement efficiency.

[0017] When the punching tool forms the air barrier film, the film pressing roller tensions the punching part of the air barrier film, which can effectively prevent the side of the compressed part of the air barrier film from warping during punching, and improve the flatness of the subsequent side table heat sealing. The whole process is as shown in the Chinese patent publication number CN220593815U. After the air barrier film is punched and formed, it can replace the bottom shell of the original product to facilitate the accommodation of the core material. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the utility model and do not constitute a limitation on the utility model.

[0024] This device is part of the entire production line. It is only used to press and shape the air barrier film required for the vacuum insulation panel to form a cavity that can accommodate the core material. The air barrier film on the roller can replace the original bottom shell. On the one hand, it reduces the overall material loss. On the other hand, when the continuous air barrier film is transmitted, the core material falls into the cavity of the air barrier film, which can drive the core material to be transmitted to the subsequent processing steps without the need to drive the core material again. The continuous air barrier film also facilitates the free selection of the position during subsequent packaging, thereby improving the flexibility of packaging.

[0025] like Figure 1 and Figure 3 As shown, a film forming device for processing a vacuum insulation panel includes a base frame 10, an auxiliary component 20 and a stamping component 30. The base frame 10 includes a long strip of transmission pressure plate 103 for conveying an air barrier film; the auxiliary component 20 can tension the side of the air barrier film and move along the transmission direction of the air barrier film on the base frame 10; the stamping component 30 is installed on the base frame 10, and can stamp the force-bearing end of the air barrier film tensioned by the auxiliary component 20, so that the stamped area forms a continuous cavity that can accommodate the core material. Among them, the base frame 10 also includes a support frame 101 and a workbench 102 installed on the support frame 101 away from the ground, and the auxiliary parts 20 and the stamping parts 30 are both arranged on the workbench 102; a slide rail is arranged on the workbench 102 along the conveying direction of the air barrier sheet, and the auxiliary part 20 moves on the workbench 102 through the slide rail, so that the auxiliary part 20 can tighten the two sides of the air barrier film and drive the air barrier film to move to the stamping part 30, so as to improve the conveying effect of the air barrier film and avoid the air barrier film from missing the transmission structure. The stamping part 30 can stamp and form the air barrier film that fits the transmission platen 103, so that after the air barrier film is formed, it fits on the transmission platen 103 and has the same cross-section as the transmission platen 103. The core plate can be placed in the stamping area of ​​the air barrier film. Therefore, on the long strip transmission platen 103, multiple core plates can be placed in an interval manner one after another, and it is only necessary to maintain the distance between the multiple core plates. After the core plate is placed, it will move together with the air barrier film, which is convenient for subsequent heat sealing operations.

[0026] like Figure 1 and Figure 2 As shown, the auxiliary component 20 includes a movable plate 201 installed on the base frame 10, and the movable plate 201 is provided with tensioning parts on both sides of the air barrier film, and the tensioning parts laterally tension the air barrier film, wherein the movable plate 201 moves along the workbench 102 through a slide rail, and the tensioning part is used to tension the two ends of the air barrier film, and the stamping part 30 punches the tensioned part of the air barrier film to make the molding of the air barrier film more precise to prevent its periphery from warping.

[0027] like Figure 2As shown, the tensioning part includes a film pressing roller 202 arranged on the movable plate 201, and the film pressing roller 202 presses and tensions the side of the air barrier film. Specifically, the film pressing roller 202 can be selected individually or in plurality. If multiple film pressing rollers are used, they can be symmetrically arranged on both sides of the air barrier film, such as two groups, three groups, etc., and it is only necessary to squeeze and tension the two sides of the air barrier film by using rollers.

[0028] Embodiment 1:

[0029] A single film pressing roller 202 is used. When the air barrier film passes through the film pressing roller 202, one side of the air barrier film is attached to the table top of the movable plate 201 frame, and the film pressing roller 202 on the other side presses the air barrier film toward the frame, thereby pressing the side of the air barrier film. The table top of the frame can be set above the air barrier film, and the film pressing roller 202 is set below the air barrier film. It is preferred to set the table top of the frame below the air barrier film, and the film pressing roller 202 is set above the air barrier film, which can reduce the interference problem of the slide rail between the movable plate 201 and the workbench 102.

[0030] Embodiment 2:

[0031] The film pressing roller 202 includes an upper pressing roller 2021 and a lower pressing roller 2022 on both sides of the air barrier film and rotated on the movable plate 201 frame, wherein the upper pressing roller 2021 and the lower pressing roller 2022 can approach each other, and approaching each other not only refers to the upper pressing roller 2021 and the lower pressing roller 2022 moving toward each other at the same time, but also refers to the upper pressing roller 2021 moving toward the lower pressing roller 2022, or the lower pressing roller 2022 moving toward the upper pressing roller 2021, the upper pressing roller 2021 is located above the air barrier film, and the lower pressing roller 2022 is located above the air barrier film. Below the film, the lower pressure roller 2022 and the upper pressure roller 2021 can move toward each other synchronously on the movable plate 201 frame, and the two are close to each other, and jointly squeeze the side of the air barrier film to tension the two sides of the air barrier film; in addition, one of them can be arranged to be movable and the other is fixed on the movable plate 201 frame. Preferably, the upper pressure roller 2021 is arranged to be able to move toward the lower pressure roller 2022, and the upper pressure roller 2021 presses the air barrier film against the lower pressure roller 2022, so that the two are squeezed against each other, and the side of the air barrier film is tensioned.

[0032] On the basis of the above two embodiments, a first telescopic cylinder 203 is installed on the frame of the movable plate 201, and the first telescopic cylinder 203 drives the upper pressure roller 2021 and the lower pressure roller 2022 to move toward each other, or the first telescopic cylinder 203 drives the upper pressure roller 2021 to move toward the lower pressure roller 2022, or the first telescopic cylinder 203 drives the lower pressure roller 2022 to move toward the upper pressure roller 2021, so that the side of the air barrier film is tensioned. No matter whether the upper pressure roller 2021 or the lower pressure roller 2022 needs to move, it is driven by the first telescopic cylinder 203. The first telescopic cylinder 203 is preferably pneumatic. The specific reason is that the air barrier film does not need to use excessively high pressure, and only needs to play a tensioning role.

[0033] like Figure 2 As shown, the film pressing rollers 202 on both sides can be adjusted in position along the lateral direction of the air barrier film to accommodate air barrier films of different widths, wherein the frames on both sides of the movable plate 201 move back and forth via slide rails, and the two frames are driven mutually by screws, so that the relative position relationship can be adjusted to facilitate the use of air barrier films of different widths.

[0034] like Figure 2 and Figure 3 As shown, the stamping part 30 includes a bracket 301 installed on the side of the air barrier film away from the transmission pressure plate 103, and a stamping tool 303 is slidably arranged on the bracket 301 and perpendicular to the direction of the air barrier film. The stamping tool 303 is adapted to the transmission pressure plate 103, and the air barrier film is formed between the two to form a cavity for accommodating the core material. A second telescopic cylinder 302 is also fixedly mounted on the bracket 301 to drive the punching tool 303 to approach or move away from the air barrier film, wherein the punching tool 303 is driven by the second telescopic cylinder 302, and the second telescopic cylinder 302 is preferably pneumatic. The piston rod of the second telescopic cylinder 302 extends to drive the punching tool 303 to approach the air barrier film, so that the air barrier film is pressed against the transmission plate 103 by the punching tool 303, and the air barrier film is formed into a cavity that can accommodate the core material. The piston rod of the second telescopic cylinder 302 contracts, and the air barrier film is transmitted along with the subsequent driving wheel of the transmission plate 103 until the unpunched part of the air barrier film moves to that place, and then it can be punched again by the second telescopic cylinder 302.

[0035] like Figure 3 As shown, the cross-section of the punching tool 303 is convex, and the cross-section of the transmission platen 103 is concave to match the punching tool 303. The cross-section of the air barrier film can be formed into a concave shape, or the cross-section of the air barrier film can be punched into an approximately concave shape, such as modifying the edge of the concave shape to an inclined state or setting it to an arc shape. It can be adjusted as needed. It is preferred to form the air barrier film into a concave cross-section so that the core material can be placed. The two lateral ends of the air barrier film are pressed by the upper pressure roller 2021 and the lower pressure roller 2022. When the punching tool 303 is stamped and formed, the air barrier film can better fit the transmission platen 103 and the punching tool 303 to avoid wrinkles in the air barrier film.

[0036] When in use, the film pressing roller 202 is Figure 1The position is the initial state, the film pressing roller 202 presses and tensions the side of the air barrier film, and then the moving plate 201 conveys the air barrier film to the bottom of the punching tool 303, and the second telescopic cylinder 302 drives the punching tool 303 to press down toward the air barrier film, and the upper pressing roller 2021 and the lower pressing roller 2022 rotate with the side of the air barrier film to prevent the side of the air barrier film from being pulled during punching. At the same time, the side of the air barrier film is also tensioned and limited to prevent it from warping, until the air barrier film rests on the transmission pressure plate 103, and a concave air barrier film is formed at the punching tool 303, which is used as the lower diaphragm of the vacuum insulation panel. Figure 3 As shown, the core material can be placed in the concave cavity, which can limit the position of the core material. As the air barrier film is gradually transported by the transmission pressure plate 103, the core material will move with the air barrier film, and the film pressing roller 202 will loosen the side of the air barrier film that has been punched, and move to the area where the air barrier film is to be punched through the movable plate 201 again, and tension it again through the film pressing roller 202. As the movable plate 201 moves to the punching tool 303 again, the punching tool 303 punches and forms the air barrier film in this area, and the film pressing roller 202 tensions and limits the side of the air barrier film. After stamping and forming, the above operations are repeated again, and an air barrier film unwound from a roll can be gradually punched into a long strip, and a through core material placement cavity is formed at the top, which is convenient for transportation as well as subsequent cutting and heat sealing.

[0037] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
