Description

Technical Field

[0001] This utility model relates to the field of edge sealing technology for film-coated sheets, and in particular to a film-peeling machine. Background Technology

[0002] Most furniture is made of wood panels.

[0003] In furniture board manufacturing, the conventional practice for edge banding of laminated boards is to cut and bandage them manually, or use tools. Due to the manual involvement, there are many problems in the edge banding process of laminated boards.

[0004] If manual edge sealing is used, the film on the laminated board needs to be lifted and cut, which is labor-intensive. If tools are used for manual edge sealing, edge sealing strips will remain after most laminated boards are sealed, requiring secondary work to remove the edge sealing strips.

[0005] Therefore, solutions to the above problems are urgently needed. Utility Model Content

[0049] As a preferred embodiment of the present application, as Figure 1 A film tearing machine, comprising:

[0050] A bracket 1 in an "丄" shape;

[0051] A transmission device 2 arranged on the left side of the bracket 1. The transmission device 2 is used to realize the function of conveying the sheet material. In the transmission device 2, an upper transmission wheel 201 and a lower transmission wheel 202 are arranged at intervals up and down. The transmission device 2 restricts the conveying path of the sheet material with a film through the upper transmission wheel 201 and the lower transmission wheel 202;

[0052] A first film tearing device 3 arranged on the right side of the bracket 1. The first film tearing device 3 is used to realize the function of刨除 the adhesive film on the sheet material with a film. In the first film tearing device 3, a first film tearing tool 300 is configured. The first film tearing tool 300 is arranged close to the conveying path. The first film tearing device 3 preliminarily刨除 the adhesive film on the edge of the sheet material with a film through the first film tearing tool 300;

[0053] A second film tearing device 4 arranged on the left side of the bracket 1. The second film tearing device 4 is used to realize the function of刨除 the adhesive film on the sheet material with a film. In the second film tearing device 4, a second film tearing tool 400 is configured. The second film tearing tool 400 is arranged close to the conveying path. The second film tearing device 4刨除 the adhesive film on the edge of the edge of the sheet material with a film through the second film tearing tool 400.

[0054] It should be noted that there is an unclear expression "刨除" in some parts of the original text. It may need to be further clarified according to the actual situation to ensure more accurate translation.The film-coated sheet enters from the position of the first film-removing device 3 in the conveying path. The first film-removing device 3 performs preliminary film removal treatment on the film-coated sheet. After the first film-removing device 3 completes the treatment, the preliminarily treated film-coated sheet is transferred to the second film-removing device 4, which completes the final treatment of the edge sealing strip of the film-coated sheet.

[0055] This embodiment of a film-tearing machine includes a support 1, a transmission device 2 disposed on the left side of the support 1, a first film-tearing device 3 disposed on the right side of the support 1, and a second film-tearing device 4 disposed on the left side of the support 1. The transmission device 2 uses an upper transmission wheel 201 and a lower transmission wheel 202 to constrain the conveying path of the film-coated sheet. In the conveying path, the first film-tearing blade 300 on the first film-tearing device 3 performs preliminary edge sealing treatment on the film-coated sheet, and the second film-tearing blade 400 on the second film-tearing device 4 further removes the edge sealing strip after the preliminary edge sealing treatment of the film-coated sheet, thereby realizing the mechanized application of edge sealing treatment of the film-coated sheet and achieving efficient processing.

[0056] In this embodiment, the first film-tearing blade 300 and the second film-tearing blade 400 are misaligned.

[0057] In practical use, the setting position of the first film-tearing cutter 300 determines the maximum width of the edge sealing of the film-coated sheet. The film-coated sheet after being removed by the first film-tearing cutter 300 has an edge sealing strip, which is then removed by the second film-tearing cutter 400. The second film-tearing cutter 400 is only used for subsequent processing of the edge sealing strip on the film-coated sheet.

[0058] For a specific example, if the width of the edge to be removed is 5cm, the first film-tearing blade 300 is set at a position 5cm from the edge of the film-coated board, while the second film-tearing blade 400 is set at a position less than 5cm from the edge of the film-coated board. This demonstrates the staggered setting of the first film-tearing blade 300 and the second film-tearing blade 400.

[0059] Preferably, the first film-tearing blade 300 is an annular first film-tearing blade 300;

[0060] The second film-tearing tool 400 is an annular second film-tearing tool 400;

[0061] Multiple triangular cutting edges are provided on both the first film-tearing cutter 300 and the second film-tearing cutter 400. During the rotation of the first film-tearing cutter 300 and the second film-tearing cutter 400, the triangular cutting edges are used to remove the adhesive film, and the beveled design guides the removed adhesive film outside the equipment to avoid the removed adhesive film remaining on the board and affecting the edge sealing effect.

[0062] In this embodiment, the specific components of the film-tearing machine are as follows: Figure 1 and Figure 2 As shown, the first film-tearing device 3 includes:

[0063] First mounting plate 31; first drive motor 32, the first drive motor 32 is fixedly mounted on the first mounting plate 31, and the drive end of the first drive motor 32 is connected to the first film tearing cutter 300.

The first up-and-down driving cylinder 353 is installed on the top of the first testing plate 351 and the driving end of the first up-and-down driving cylinder 353 is connected to the first moving plate 331.

[0070] The first pressure gauge 352 is used to detect the pressure of the first film-tearing blade 300 on the film-coated sheet during operation. An external controller is used to drive the first up-and-down drive cylinder 353 in an automated control manner to adjust the gap between the first film-tearing blade 300 and the film-coated sheet, so as to prevent the first film-tearing blade 300 from chipping the sheet.

[0071] In this embodiment, the structure of the docking transmission device 2 is as follows: Figure 1 and Figure 3 As shown, the transmission device 2 includes:

[0072] The second upper mounting plate 21 has a drive wheel 201 mounted on one side of the first upper mounting plate.

The second upper moving plate 231 and the second lower moving plate 232 are both installed on the second vertical slider (not shown). The second upper moving plate 231 and the second lower moving plate 232 can move up and down through the second vertical slide rail 241 and the second vertical slider (not shown).

[0084] The second upper tearing cutter 401 moves synchronously with the upper drive wheel 201 and the second lower tearing cutter 402 moves synchronously with the lower drive wheel 202. This allows the second upper tearing cutter 401 and the second lower tearing cutter 402 to be fixed in position on the second upper mounting plate 21 and the second lower mounting plate 22. This simplifies the operation steps of adjusting the relative positions of the second upper tearing cutter 401 and the upper drive wheel 201 and the second lower tearing cutter 402 and the lower drive wheel 202 when processing boards of different thicknesses.
