[0005] The invention is further configured such that the fixing base is provided with a guide strip, the bottom of the pressure plate is provided with a slot, the guide strip is inserted into the slot, and the pressure plate can move along the length direction of the guide strip so that the pressure plate moves toward the corresponding extension plate.

[0006] The invention is further configured such that the movable rod includes a rod portion one and a rod portion two located above the rod portion one, the rod portion two located below the rod portion three, and the rod portion one is able to fit against the inner wall of the extension plate.

[0007] The invention is further configured such that a gap is formed between the second rod portion and the inner wall of the corresponding extension plate.

[0008] The invention is further configured such that the second rod has a groove, the groove opens toward the side of the corresponding extension plate, the groove is connected to a channel one and a channel two, and a negative pressure device is connected to the outside of the channel two.

[0009] The invention is further configured such that the extension plate has a plurality of first slots, and the pressure plate has a first protrusion corresponding to each of the first slots, the first protrusion being able to be inserted into the first slot.

[0010] The present invention is further configured such that the first slots are distributed vertically along the inner wall of the extension plate, the depth of the first slot located at the bottom is greater than that of the other first slots, and the height of the first protrusion located at the bottom is greater than that of the other first protrusions.

[0011] The invention is further configured such that a fixed block is connected to the bottom of the movable rod, a lifting plate is connected to the fixed block, and a driving component is connected to the lifting plate to achieve up and down movement.

[0012] The present invention also adopts the following technical solution: a method for treating the edge film of a decorative panel, using a decorative panel edge film treatment device, comprising the following steps:

[0013] ① Insert the decorative panel with the film attached into the boss;

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figure 1 As shown, this embodiment discloses a decorative panel edge film treatment device, including a fixing base 1. The fixing base 1 has a boss 11 at its upper end. The boss 11 has a rectangular frame structure and an opening at its top, allowing the decorative panel 2 to be inserted and installed. Figure 4 , Figure 6 As shown, the main body of decorative panel 2 is arc-shaped, and decorative panel 2 includes extension panels 21 located on both sides. Figure 5As shown, the inner wall of the extension plate 21 is provided with a first slot 211 and a second slot 212. The second slot 212 is located above the first slot 211. Multiple first slots 211 are distributed along the inner wall of the extension plate 21. The depth of the first slot 211 located at the bottom is greater than that of the other first slots 211. The first slot 211 with the largest depth is close to the bottom of the extension plate 21.

[0032] like Figure 1 , Figure 2 As shown, the decorative panel 2 is made of plastic. The outer wall of the decorative panel 2 is covered with a film 22. The film 22 has a very thin wall thickness, less than 0.03 mm. The film 22 is shown in the figure in a thickened manner to show its state.

[0033] The membrane body 22 includes side membranes 221 located on both sides. The side membranes 221 are attached to the extension plate 21 and extend from the outer wall of the extension plate 21, around the bottom surface of the extension plate 21, to the inner wall of the extension plate 21. A pressure plate 23 is installed on the inner wall of the extension plate 21. The pressure plate 23 has a second protrusion 232 that can be inserted into a second slot 212 to allow the extension plate 21 and the pressure plate 23 to be interference-fitted. The pressure plate 23 has a first protrusion 231 that corresponds one-to-one with the first slot 211. The first protrusion 231 can be inserted into the first slot 211. The protrusion height of the lowest first protrusion 231 is greater than that of the other first protrusions 231. The membrane body 22 is pressed and fixed by the pressure plate 23 and the inner wall of the extension plate 21 (the side membrane 221 between the pressure plate 23 and the inner wall of the extension plate 21 is not shown).

[0034] Combination Figure 2 , Figure 7 The fixed base 1 is provided with a guide bar 14, and the bottom of the pressure plate 23 is provided with a slot 233. The guide bar 14 is inserted into the slot 233, and the pressure plate 23 can move along the length direction of the guide bar 14 so that the pressure plate 23 can move towards the corresponding extension plate 21 and be inserted into the extension plate 21 for fixation.

[0035] Combination Figure 1 , Figure 2 The fixed base 1 has a sliding rod 42 slidably connected to both sides. The fixed base 1 is provided with a sliding groove 13. The sliding rod 42 can move up and down along the inner wall of the sliding groove 13. Specifically, the bottom of the sliding rod 42 is connected to a fixed block 41. The fixed block 41 is connected to a lifting plate 4. The lifting plate 4 is connected to a driving component 31 to realize up and down movement. The driving component 31 is a hydraulic cylinder.

[0036] like Figure 3 As shown, after the pressure plate 23 is installed on the fixed base 1, the second protrusion 232 is higher than the moving rod 42. The moving rod 42 includes a rod portion 423 located at the top. When the moving rod 42 moves upward, one side of the rod portion 423 moves against the inner wall of the extension plate 21 so as to fit the edge film 221 against the inner wall of the extension plate 21.

[0037] The movable rod 42 includes a first rod portion 421 and a second rod portion 422 located above the first rod portion 421. The second rod portion 422 is located below the third rod portion 423. The first rod portion 421 can fit against the inner wall of the extension plate 21 so that the edge film 221 at the bottom corner of the inner wall of the extension plate 21 forms a fold.

[0038] A gap is formed between the second rod part 422 and the inner wall of the corresponding extension plate 21. The second rod part 422 is provided with a groove 4221. The groove 4221 opens towards the side of the corresponding extension plate 21. The groove 4221 is connected to the first channel 424 and the second channel 425. The second channel 425 is connected to a negative pressure device through the air pipe 6. The fixed base 1 is provided with a groove 12. The air pipe 6 passes through the groove 12. The bottom of the first channel 424 is closed by the fixing block 41.

[0039] like Figure 1 As shown, the decorative panel edge film treatment device includes a cam 51. After installation, the pressure plate 23 is located on both sides of the cam 51. The cam 51 is connected to a drive rod 5, which is driven to rotate by a motor 32. The rotation of the cam 51 can push the pressure plate 23 to move towards the corresponding extension plate 21. The motor 32 and the drive component 31 are both mounted on the base plate 3.

[0040] The above-mentioned decorative panel edge film treatment device includes the following steps:

[0041] ①For example Figure 1 As shown, the decorative panel 2 with the film 22 attached is inserted into the boss 11, as follows. Figure 3 As shown, the side membrane 221 is horizontal and extends out of the inner wall of the extension plate 21 (that is, the side membrane 221 extends away from the outer wall of the extension plate 21 and exceeds the inner wall of the extension plate 21).

[0042] ②For example Figure 1 , Figure 3 , Figure 7 As shown, the pressure plate 23 is installed on the fixed base 1, and the guide strip 14 is inserted into the slot 233.

[0043] ③ For example Figure 3 As shown, the moving rod 42 moves upward to its limit position, so that the side membrane 221 bends upward and fits against the inner wall of the extension plate 21 (i.e., Figure 2 (The state shown).

[0044] ④ The rod part 423 moves downward, and at the same time, negative pressure is generated in the groove 4221. The side membrane 221 is pulled downward on the inner wall surface of the extension plate 21. At the bottom of the inner wall surface of the extension plate 21, the side membrane 221 forms an arch due to the traction of the negative pressure.

[0045] ⑤ The cam 51 rotates and pushes the pressure plate 23 so that the pressure plate 23 is close to the corresponding extension plate 21. The second protrusion 232 is inserted into the second slot 212, and at the same time the side film 221 is clamped by the second protrusion 232 and the inner wall of the second slot 212.

[0046] ⑥ As the third rod 423 continues to move downward and away from the bottom of the extension plate 21, the arched portion of the side membrane 221 at the bottom of the inner wall surface of the extension plate 21 is folded by the third rod 423, thereby increasing the length of the side membrane 221 at the bottom of the inner wall surface of the extension plate 21.

[0047] ⑦ The cam 51 rotates to push the pressure plate 23 so that the first protrusion 231 is inserted into the first slot 211, thereby completing the clamping of the edge film 221 by the pressure plate 23 and the extension plate 21, so that the edge film 221 is firmly fixed to avoid the phenomenon of film detachment.

[0048] When the first protrusion 231 is inserted into the first slot 211, the first protrusion 231 located at the bottom is inserted into the corresponding first slot 211 first. Since there is a margin in the length of the side film 22 at this point, the first protrusion 231 extends this margin into the first slot 211 when it is inserted, so as to avoid excessive stretching of the side film 22 when the first protrusion 231 is inserted, effectively protecting the side film 22 and preventing the side film 22 from becoming too tight, which would lead to a decrease in toughness or direct tearing.

[0049] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
