Description

Technical Field

[0001] This utility model relates to the field of wood veneer film application technology, specifically to a pressing device for applying wood veneer film. Background Technology

[0002] Decorative veneer plywood, also known as wood veneer panel, is a decorative material used for interior decoration or furniture surfaces. It is made by slicing natural wood or engineered wood into thin sheets of a certain thickness, adhering them to the surface of plywood, and then hot-pressing them together.

[0003] In the production process of wood veneer panels, lamination is an important step, which involves firmly attaching the protective or decorative layer to the wood veneer panel. In most wood veneer panel production, after the decorative surface is laminated, a protective film is applied to protect the front and decorative surfaces from damage and scratches. In actual production, air bubbles may appear in some parts of the protective film lamination process. Generally, the air bubbles are scraped off manually, and excess protective film on both sides of the wood veneer panel is also trimmed manually. This is time-consuming and labor-intensive, increasing the labor intensity of the workers. Utility Model Content

Detailed Implementation

[0021] To better understand the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, further illustrates this utility model.

[0022] like Figures 1-6 As shown, a pressing device for applying film to wood veneer panels includes a frame 100, a support platform 200, and a pressing and venting mechanism 300. The frame 100 is fixed on the ground, and the support platform 200 is fixed on the frame 100. The pressing and venting mechanism 300 is arranged above the support platform 200. The support platform 200 is used to place the wood veneer panel after film application, and the pressing and venting mechanism 300 is used to expel the air bubbles in the protective film of the wood veneer panel after film application on the support platform 200.

[0023] Specifically, the pressing and venting mechanism 300 includes a mounting frame 301, a hydraulic cylinder 302, a track seat 303, a pressure roller 304, and a pressure roller mounting seat 305. The mounting frame 301 is fixed to the ground, and the hydraulic cylinder 302 is fixed to the mounting frame 301. The output end of the hydraulic cylinder 302 is fixedly connected to the track seat 303. The track seat 303 includes two guide rods 3031 symmetrically arranged front and rear, with a rack 3032 fixed between the two guide rods 3031. The pressure roller 304 is rotatably mounted on the pressure roller mounting seat 305, and the pressure roller mounting seat 305 can slide along the guide rods 3031. A motor 306 is fixed on the pressure roller mounting seat 305, and the output end of the motor 306 is connected to a drive gear 307. The drive gear 307 meshes with the rack 3032. In use, the wood veneer panel is placed on the support platform 200 with the side of the wood veneer panel protective film that needs to be vented facing upwards. The hydraulic cylinder 302 is started, and the hydraulic cylinder 302 drives the track mounting seat 403 to move downwards. The pressure roller 304 and the pressure roller mounting seat 305 also move downwards. Initially, the pressure roller mounting seat 305 is located on the left side above the wood veneer panel. After the pressure roller 304 presses the wood veneer panel tightly, the motor 306 starts and drives the drive gear 307 to rotate. With the cooperation of the drive gear 307 and the rack 3032, the pressure roller mounting seat 305 moves to the right along the guide rod 3031. Under the action of the pressure roller 304, the air bubbles in the wood veneer panel protective film are squeezed to the right until they are expelled.

[0024] Preferably, the support platform 200 includes a support plate 201 fixed to the frame 100. A limit block 202 is provided on the right side of the support plate 201. A fixed stop bar 203 is provided on the rear side of the support plate 201. The fixed stop bar 203 is fixed on the support plate 201. The height of the fixed stop bar 203 is lower than the thickness of the wood veneer panel. A movable stop bar 204 is provided on the front side of the support plate 201. The movable stop bar 204 is slidably disposed on the support plate 201. A first cylinder 205 is connected to the side of the movable stop bar 204 away from the fixed stop bar 203. In use, the operator places the wood veneer panel on the support platform 200 so that the rear side of the wood veneer panel abuts against the fixed stop bar 203 and the right side of the wood veneer panel abuts against the limit block 202. Then the first cylinder 205 is activated. The first cylinder 205 drives the movable stop bar 204 to move toward the wood veneer panel until the movable stop bar 204 abuts against the wood veneer panel.

[0025] Preferably, the support plate 201 has a plurality of mounting holes for the support rollers 400 evenly spaced. Each support roller 400 is installed within one of the mounting holes. Each support roller 400 includes a roller body 401, a roller frame 402, and a mounting base 403. The roller body 401 is rotatably mounted on the roller frame 402. A connecting rod 4021 is provided at the lower part of the roller frame 402. The connecting rod 4021 is sleeved within a sleeve 4031 fixed to the mounting base 403. A spring 404 abuts against the lower end of the connecting rod 4021. The spring 404 is located away from the connecting rod 4021. The end is fixed to the bottom of the sleeve 4031. The top of the sleeve 4031 is provided with a limiting part 405 to prevent the connecting rod 4021 from disengaging from the sleeve 4031. The roller body 401 is slightly higher than the surface of the support plate 201, which makes it convenient for workers to move the wood veneer panel and avoids excessive contact and scratches between the wood veneer panel and the support plate 201 during movement. The purpose of setting the spring 404 is that when the pressure exhaust mechanism 300 is pressed down, the spring 404 is compressed, which makes the back of the wood veneer panel contact the support plate 201, making the whole process more stable.

[0026] Preferably, a scraper is fixed to the left side of the pressure roller 304. The scraper is made of rubber material, which makes the air release effect of the protective film on the wood veneer better.

[0027] Preferably, the support plate 201 has at least two suction cup mounting holes 206 in the middle, and a pneumatic suction cup 207 is installed in the suction cup mounting holes 206. The pneumatic suction cup 207 is fixed on the suction cup frame 208. The suction cup frame 208 is connected to the second cylinder 209 through a support rod. In use, in order to balance the wood veneer panel as a whole, when the pressure roller 304 acts on the middle of the wood veneer panel, the second cylinder 209 is activated to drive the suction cup frame 208 upward. The pneumatic suction cup 207 is activated after contacting the wood veneer panel to firmly suction the wood veneer panel.

[0028] Preferably, a side-tidying mechanism 500 is provided on the left side of the pressing and venting mechanism 300. The side-tidying mechanism 500 includes two tidying plates 501 disposed on the left side of the pressure roller mounting base 305. One end of each tidying plate 501 is connected to the pressure roller mounting base 305, and the other end of each tidying plate 501 is connected to a connecting post 502. The end of the connecting post 502 away from the tidying plate 501 is slidably connected to a guide rod 3031. A heating frame 503 is connected to the outer side of each tidying plate 501. An electric heating wire is disposed inside the heating frame 503. After the pressure roller 304 completes the removal of air bubbles, the pressure roller 304 continues to move to the right so that the wood veneer panel will not interfere with it when it rises. At this time, the second cylinder 209 works again, and the wood veneer panel moves upward under the drive of the pneumatic suction cup 207. Simultaneously, the heating wire inside the heating frame 503 operates, transferring heat to the arranging plate 501. As the wood veneer panel rises, the excess protective film on both sides of the wood veneer panel is pressed down onto the two sides of the wood veneer panel by the arranging plate 501. The arranging plate 501 is made of metal; in this embodiment, stainless steel is used. The heat from the arranging plate 501 shapes the protective film on both sides. Then, the second cylinder 209 returns to its original position. When the back of the wood veneer panel contacts the support plate 201, the suction cup stops working, and the second cylinder 209 returns to its original position. A temperature sensor can be installed at the heating frame 503. The temperature sensor is connected to a controller, which is connected to the heating wire switch. During use, the heating wire stops working when the temperature is higher than a certain temperature, and it operates to heat when the temperature is lower than a certain temperature.

[0029] Working Principle: During use, the operator places the wood veneer panel on the support platform 200, ensuring the back of the panel abuts against the fixed stop bar 203 and the right side abuts against the limit stop block 202. Then, the first cylinder 205 is activated, moving the movable stop bar 204 towards the wood veneer panel until it abuts against it, with the side of the protective film to be de-bubbled facing upwards. The hydraulic cylinder 302 is then activated, moving the track mounting base 403 downwards. The pressure roller 304 and pressure roller mounting base 305 also move downwards. Initially, the pressure roller mounting base 305 is located on the upper left side of the wood veneer panel. After the pressure roller 304 presses the wood veneer panel firmly, the motor 306 starts, driving the drive gear 307 to rotate. With the cooperation of the drive gear 307 and rack 3032, the pressure roller mounting base 305 moves to the right along the guide rod 3031. Under the action of the pressure roller 304, the wood veneer panel is protected... The air bubbles in the film are squeezed to the right until they are expelled. When the pressure roller 304 acts on the middle of the wood veneer panel, the second cylinder 209 is activated, driving the suction cup frame 208 upward. The pneumatic suction cup 207 is activated after contacting the wood veneer panel, sucking the wood veneer panel tightly. When the pressure roller 304 moves to the right side of the wood veneer panel, the second cylinder 209 works again. Driven by the pneumatic suction cup 207, the wood veneer panel moves upward. At the same time, the heating wire in the heating frame 503 works, and the heating frame 503 transfers heat to the arranging plate 501. As the wood veneer panel rises, the excess protective film on both sides of the wood veneer panel is pressed down on the two sides of the wood veneer panel by the arranging plate 501. The arranging plate 501 is made of metal, and in this embodiment, stainless steel plate is used. The heat of the arranging plate 501 shapes the protective film on both sides. Then the second cylinder 209 returns to its original position. When the back of the wood veneer panel contacts the support plate 201, the suction cup stops working, and the second cylinder 209 returns to its original position.
