[0023] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the cold pressing device proposed in this utility model. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model. The same or similar reference numerals in the drawings represent the same or similar parts.

[0024] Please see Figures 1 to 4This utility model provides a cold pressing device, including a cold pressing box 1. A movable rolling assembly for rolling and cleaning wood is installed on the top of the cold pressing box 1. The movable rolling assembly includes a fixed frame 2 fixedly connected to the top of the cold pressing box 1. A bidirectional threaded rod 3 is rotatably connected to the inner side of the fixed frame 2. A turntable 4 is fixedly connected to the end face of the bidirectional threaded rod 3. Two movable plates 5 are threadedly connected to the outer surface of the bidirectional threaded rod 3. A limit post 6 is fixedly connected to the inner side of the fixed frame 2. A mounting frame 7 is fixedly connected to the outer side of the movable plates 5. A rolling roller 8 is rotatably connected to the inner side of the mounting frame 7. An adhesive sleeve 9 is adhered to the outer surface of the rolling roller 8. The cold pressing assembly for bidirectional rapid cold pressing of wood is installed inside the cold pressing box 1. During loading, the wood passes through the two rolling rollers 8, allowing the adhesive sleeve 9 on the outer surface of the rolling roller 8 to remove fine wood chips, dust, and debris from both sides of the wood using its adhesive properties, preventing the formation of dents, scratches, or color differences, and ensuring the aesthetic appearance of the wood.

[0025] In addition, the operator can rotate the turntable 4 clockwise or counterclockwise, so that the bidirectional threaded rod 3 rotates clockwise or counterclockwise inside the fixed frame 2, thereby driving the two movable plates 5 to move closer or further away from each other, and thus adjusting the distance between the two rolling rollers 8 to suit wood boards of different thicknesses.

[0026] In this embodiment, the cold pressing assembly includes a processing box 10 fixedly connected to the inside of the cold pressing box 1. Cylinders 11 are fixedly connected to both the left and right sides of the cold pressing box 1. The output shaft of the cylinder 11 is fixedly connected to a pressure plate 12. The two cylinders 11 can drive the two pressure plates 12 to quickly approach each other, thereby rapidly cold pressing the wood in both directions to improve processing efficiency.

[0027] It should be noted that this application can ensure that the piston rods of the two cylinders 11 extend and retract simultaneously by using a synchronization controller or synchronization valve, thereby achieving synchronous operation. These synchronization devices are common and mature in the field of pneumatic control, so they will not be described in detail in the specific embodiments.

[0028] It should be noted that neither the front of the cold pressing chamber 1 nor the processing chamber 10 is sealed, and the output shaft of the cylinder 11 passes through both the cold pressing chamber 1 and the processing chamber 10.

[0029] In this embodiment, electric push rods 13 are fixedly connected to the left and right sides of the bottom of the cold pressing box 1. The output shaft of the electric push rod 13 is fixedly connected to a scraper 14 for cleaning the pressure plate 12. Rubber pads are glued to the left and right sides of the scraper 14. Storage slots 15 for storing the scraper 14 are opened on the left and right sides of the bottom of the processing box 10. After pressing, the electric push rod 13 can drive the scraper 14 to move vertically upward, thereby scraping away any debris that may be stuck to the outer surface of the pressure plate 12 through the rubber pads glued to the left and right sides of the scraper 14.

[0030] Specifically, the bidirectional threaded rod 3 passes through the fixed frame 2 and extends to its outer side, and the movable plate 5 is slidably connected to the limiting post 6. The limiting post 6 achieves the effect of slidingly limiting the movable plate 5 to improve its movement stability.

[0031] Specifically, the roller 8 has a hollow structure, and the adhesive sleeve 9 is a paper adhesive. The roller 8 and the adhesive sleeve 9 are rolling dust-removing tools. The outer layer of adhesive paper, i.e. the adhesive sleeve 9, can be repeatedly peeled off to ensure the cleaning effect.

[0032] In this embodiment, support legs 16 are provided around the bottom of the cold pressing box 1, and a movable door 17 for unloading is hinged to the front of the processing box 10. The movable door 17 is easy to open and close, which makes it convenient for workers to unload the wood after pressing.

[0033] The working principle of the above embodiments is as follows:

[0034] In use, the operator can rotate the turntable 4 clockwise or counterclockwise, causing the bidirectional threaded rod 3 to rotate clockwise or counterclockwise inside the fixed frame 2. This causes the two movable plates 5 to move closer to or further away from each other, thereby adjusting the distance between the two rollers 8 to accommodate boards of different thicknesses. During loading, the wood passes through the two rollers 8, allowing the adhesive sleeves 9 on the outer surface of the rollers 8 to remove fine wood chips, dust, and debris from both sides of the wood using their adhesive properties. After cleaning, the wood falls downwards into the processing box 10 and... The wood is then pressed against the outer surface of the pressure plate 12. Then, the two cylinders 11 are activated simultaneously to drive the two pressure plates 12 to quickly approach each other, thereby rapidly cold-pressing the wood in both directions to improve processing efficiency. After pressing, the two pressure plates 12 are reset to their original positions, and the electric push rod 13 is activated to drive the scraper 14 to move vertically upward. The scraper 14 removes any debris that may be stuck to the outer surface of the pressure plate 12 by using the rubber pads attached to the left and right sides of the scraper 14. Finally, the movable door 17 is opened and closed, allowing workers to easily pull out the pressed wood from the inside of the processing box 10 for unloading.

[0035] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.

[0036] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
