Description

Technical Field

[0001] This utility model relates to the field of edge banding machine technology, and in particular to an easily adjustable edge banding and pressing device. Background Technology

[0002] In industries such as panel processing and furniture manufacturing, edge banding and lamination is an important process. Its purpose is to seal the edges of panels to prevent them from getting damp and deformed, while also improving their appearance and lifespan.

[0003] Currently, there are many types of edge banding and laminating devices on the market, but most of them have some shortcomings: On the one hand, the height adjustment mechanism of existing devices is cumbersome and has low adjustment precision, making it difficult to adapt to the processing needs of boards of different thicknesses, resulting in unstable laminating effects; on the other hand, the edges of boards often have dust, wood chips and other impurities attached to them before laminating, and most existing devices lack effective pre-treatment and cleaning mechanisms. The presence of impurities will affect the adhesion between the edge banding film and the board, easily leading to problems such as delamination and lifting; in addition, the heating and pressing mechanisms of some devices are not well coordinated, resulting in poor heating uniformity and insufficient pressing force, which further affects the quality and efficiency of edge banding and laminating. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the problem in existing edge banding machines where it is difficult to clean excess adhesive from the edge banding strip, thus affecting the neatness and aesthetics of the board edges.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model is as follows: it includes a shell and two sets of bases symmetrically fixed inside the shell. A support platform is provided on the top of the base. Several sets of cylinders are fixedly installed on the surface of the support platform. The output end of the cylinder is connected to a mounting plate. A cleaning mechanism is provided on the surface of the support platform. The cleaning mechanism includes a fixed frame fixedly connected to the surface of the rear mounting plate. Fixed columns are symmetrically fixedly connected to the surface of the fixed frame. Connecting parts are slidably connected inside the fixed columns. A pressure plate is hinged to the bottom end of the connecting parts. Two sets of scrapers are fixedly connected to the side of the pressure plate.

[0008] Preferably, when the edge banding machine is in use, the board moves along the direction of multiple sets of pressure rollers. The pressure rollers apply pressure to the edge banding strip, which is then pasted onto the edge of the board. When the board passes between two sets of pressure plates, the board will squeeze the two sets of pressure plates to flip, making the pressure plates parallel to the board. Then, the scraper on the side of the pressure plate can scrape off the excess glue and cut off the excess edge banding strip, ensuring that the edge of the board is neat and beautiful.

[0009] Furthermore, a spring is fixedly connected to the top of the connector, a spring is fixedly connected to the bottom of the connector, and a collection box is fixedly connected to the side of the housing surface near the fixing frame, which can scrape and clean plates of different thicknesses.

[0010] Furthermore, rollers are symmetrically connected inside the pressure plate to reduce wear on the sheet material.

[0011] Furthermore, a mounting plate at the front end is fixedly connected to a mounting base, a heating roller is rotatably connected to the surface of the mounting base, and a heating tube is fixedly installed inside the mounting base on the side near the heating roller to facilitate heating and softening of the edge banding strip.

[0012] Furthermore, a pressure roller is rotatably connected to the surface of the mounting plate located between the fixed base and the fixed frame, which facilitates pressing the edge banding strip onto the surface of the board.

[0013] Furthermore, a drive motor is mounted on the surface of the housing, and a connecting shaft is fixedly connected to the output end of the drive motor. A reducer is mounted on the surface of the base, and the connecting shaft is connected to two sets of reducers. Nuts are installed inside the reducers, and screws are symmetrically and fixedly connected to the bottom surface of the support platform. The screws and nuts are threaded together to facilitate the lifting and adjustment of the support platform.

[0014] Furthermore, a slider is fixedly connected to the side of the support platform near the base, and a groove is provided on the side of the base surface near the slider. The support platform slides above the base through this slider groove, improving the stability of the support platform's movement.

[0015] (III) Beneficial Effects

[0016] Convenient and precise adjustment: This utility model uses a height adjustment mechanism composed of a drive motor, connecting shaft, reducer, screw and nut to achieve synchronous and precise adjustment of the height of the bearing platform. With the guiding and limiting effect of the slider and the slide groove, the adjustment process is stable and can quickly adapt to the processing needs of plates of different thicknesses, solving the problems of cumbersome adjustment and low precision of existing devices.

[0017] Thorough impurity removal: The cleaning mechanism of this utility model uses a cylinder to drive the pressure plate down, so that the scraper fits against the surface of the board. The elasticity of spring one and spring two ensures close contact between the scraper and the board. Rollers assist in the smooth transport of the board, while the collection box collects impurities in a concentrated manner, effectively removing dust, wood chips and other impurities from the edges of the board, avoiding impurities from affecting the adhesion between the edge sealing film and the board, and improving the quality of the film pressing.

[0018] Stable film pressing quality: This utility model achieves a continuous process of "pre-pressing and positioning - heating and softening - tight pressing" through the cooperation of pressure rollers, heating rollers and heating tubes. The pressure rollers ensure accurate positioning of the edge sealing film, and the heating rollers heat evenly, so that the edge sealing film is fully attached to the edge of the board and pressed firmly, effectively avoiding problems such as delamination and curling, and improving the quality and efficiency of edge sealing and pressing.

[0019] Stable and reliable structure: The overall structure of this utility model is reasonably designed, and the components are firmly connected. The cooperation structure of slider and groove, screw and nut, etc., improves the overall stability of the device, has a long service life, is easy to maintain, and is suitable for large-scale industrial production.

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] Example 1:

[0030] See Figure 1-7This utility model provides an embodiment: it includes a housing 1 and two sets of bases 2 symmetrically fixed inside the housing 1. A support platform 4 is provided above the base 2. Several sets of cylinders 5 are fixedly installed on the surface of the support platform 4. The output end of the cylinders 5 is connected to a mounting plate 6. A cleaning mechanism 3 is provided on the surface of the support platform 4. The cleaning mechanism 3 includes a fixing frame 32 fixedly connected to the surface of the rear mounting plate 6. Fixing columns 33 are symmetrically fixedly connected to the surface of the fixing frame 32. Connecting members 34 are slidably connected inside the fixing columns 33. The bottom end of 34 is hinged with a pressure plate 35, and two sets of scrapers 36 are fixedly connected to the side of the pressure plate 35. When the edge banding machine is in use, the board moves along the direction of multiple sets of pressure rollers 7. The pressure rollers 7 apply pressure to the edge banding strip and stick the edge banding strip to the edge of the board. When the board passes between the two sets of pressure plates 35, the board will squeeze the two sets of pressure plates 35 to flip, so that the pressure plates 35 are parallel to the board. Then the scrapers 36 on the side of the pressure plate 35 can scrape off the excess glue and cut off the excess edge banding strip to ensure that the edge of the board is neat and beautiful.

[0031] A spring 37 is fixedly connected to the top of connector 34, and a spring 38 is fixedly connected to the bottom of connector 34. A collection box 31 is fixedly connected to the side of the housing 1 near the fixing frame 32. Rollers 39 are symmetrically rotatably connected inside the pressure plate 35. A fixing seat 14 is fixedly connected to the surface of the mounting plate 6 at the front end. A heating roller 13 is rotatably connected to the surface of the fixing seat 14. A heating tube 15 is fixedly installed inside the fixing seat 14 near the heating roller 13. A pressure roller 7 is rotatably connected to the surface of the mounting plate 6 between the fixing seat 14 and the fixing frame 32. The scraped waste material can be collected through the collection box 31. By setting spring 37, plates of different thicknesses can be... The compression spring 37 retracts, causing the pressure plate 35 to adhere tightly to the surface of the board, facilitating the scraper 36 to scrape and clean boards of different thicknesses. The roller 39 converts the sliding friction between the pressure plate 35 and the board into rolling friction, reducing wear on the board. The heating wire inside the heating tube 15 is energized to heat the heating roller 13, which then heats and softens the edge banding strip, allowing it to adhere firmly to the side of the board. The cylinder 5 applies constant pressure to the edge banding strip, and the rubber surface of the pressure roller 7 provides good elastic pressure, ensuring the edge banding strip adheres tightly to the board without damaging the board surface.

[0032] Example 2:

[0033] Please see Figure 1-7In this embodiment, a drive motor 9 is mounted on the surface of the housing 1, and a connecting shaft 11 is fixedly connected to the output end of the drive motor 9. A reducer 10 is mounted on the surface of the base 2, and the connecting shaft 11 is connected to two sets of reducers 10. A nut 12 is installed inside the reducer 10. A screw 8 is symmetrically fixedly connected to the bottom surface of the support platform 4, and the screw 8 and the nut 12 are threadedly connected. A slider is fixedly connected to the side of the support platform 4 near the base 2. A groove is opened on the side of the base 2 near the slider. The support platform 4 slides above the base 2 through this slider groove. By starting the drive motor 9, the connecting shaft 11 can be driven to rotate, and then the reducer 10 drives the nut 12 to rotate. Then, the screw 8 screwed to the nut 12 pushes the support platform 4 to perform lifting and lowering operations, thereby synchronously adjusting the height of multiple sets of pressure rollers 7, realizing rapid adjustment of the sealing strip pressing height, without the need to adjust the position of each pressure roller 7 individually, which reduces the difficulty of machine adjustment and improves work efficiency.

[0034] Through the above steps, when using the edge banding machine, firstly, adjust the height of the support platform 4 according to the thickness of the board to be processed: start the drive motor 9, the drive motor 9 drives two sets of reducers 10 to work synchronously through the connecting shaft 11, the reducer 10 drives the nut 12 to rotate, the nut 12 is threaded with the screw 8, driving the support platform 4 to move up and down along the base 2 until the height of the support platform 4 is suitable for the thickness of the board, after the adjustment is completed, turn off the drive motor 9; then place the board to be processed on the surface of the support platform 4, start the cylinder 5, the cylinder 5 drives the mounting plate 6 to descend, the mounting plate 6 drives the cleaning mechanism 3, the pressure roller 7 and the heating roller 13 to descend synchronously until the scraper 36 is in contact with the edge surface of the board, the roller 39 is in contact with the upper surface of the board, and the pressure roller 7 and the heating roller 13 are in contact with the edge of the board and the edge banding film respectively; at the same time, start the heating tube 15, the heating tube 15 heats the heating roller 13 so that the heating roller 13 reaches the preset temperature.

[0035] Then, the edge banding film is placed on the edge of the board, and the board is moved along the surface of the support platform 4 by the external conveying mechanism. During the movement of the board, the scraper 36 is tightly attached to the edge of the board under the elastic action of spring 37 and spring 38, cleaning the dust, wood chips and other impurities on the edge of the board. The cleaned impurities fall into the collection box 31 below. Then, the pressure roller 7 performs preliminary pressing on the edge banding film on the edge of the board to ensure accurate positioning of the edge banding film. Finally, the heating roller 13 heats and softens the edge banding film, and applies pressure to the softened edge banding film to make the edge banding film tightly attached to the edge of the board, thus completing the edge banding and pressing process.

[0036] After the film pressing is completed, turn off the heating tube 15 and the cylinder 5. The cylinder 5 drives the mounting plate 6 to rise, so that the cleaning mechanism 3, the pressure roller 7 and the heating roller 13 are separated from the board, and the processed board can be taken out.

[0037] This utility model, through its reasonable structural design, achieves highly convenient adjustment, thorough cleaning of impurities, and stable film pressing, effectively improving the quality and efficiency of edge sealing and film pressing, and is suitable for widespread application.

[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
