Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, and specifically discloses a cold pressing device for wood processing. Background Technology

[0002] Wood processing uses wood as raw material and mainly employs mechanical or chemical methods to process it, ensuring that the products retain the basic characteristics of wood. Wood processing technologies include basic processing techniques such as wood cutting, wood drying, wood gluing, and wood surface finishing, as well as functional treatment techniques such as wood protection and wood modification. During wood processing, cold presses are used to press the boards down, resulting in a stronger bond between the boards.

[0003] Chinese patent CN211278822U discloses a cold pressing device for wood processing, including a pressure plate. Support rods are provided at the four corners of the top outer wall of the pressure plate, and a top plate is provided on the top outer wall of each support rod. Two upper hydraulic rods are provided on the top outer wall of the top plate, and an upper plate is provided on the bottom outer wall of each upper hydraulic rod. A pressure plate is provided below the upper plate, and a buffer mechanism is provided between the pressure plate and the upper plate. A pressure block is provided on the top outer wall of the pressure plate. The buffer mechanism includes springs located at the four corners of the top outer wall of the pressure plate, with the top outer wall of the springs located on the bottom outer wall of the upper plate. Pull rod holes are provided at the four corners of the bottom outer wall of the upper plate, and pull rods are slidably connected to the inner side walls of the pull rod holes. This invention prevents sudden increases in pressure on the wood panels, thus preventing misalignment between the panels, improving the quality of cold pressing, preventing wear on the bottom of the panels during loading, facilitating loading, and preventing hand injuries to workers.

Furthermore, after cold pressing the board, wood chips will remain above the cold pressing table, requiring manual cleaning of the wood chips. This cleaning process is cumbersome and affects the working efficiency of the cold press. Therefore, a cold pressing device for wood processing is needed to solve this problem. Utility Model Content

Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0025] Please see Figure 1-5A cold pressing device for wood processing includes a base plate 1, two symmetrically distributed support plates 2 are fixedly connected to the upper end face of the base plate 1, a top plate 3 is fixedly connected to the upper end face of the two support plates 2, four symmetrically distributed limiting rods 5 are fixedly connected between the base plate 1 and the top plate 3, a multi-stage lamination mechanism is provided between the base plate 1 and the top plate 3, and a flipping mechanism is provided between the base plate 1 and the top plate 3.

[0026] The multi-stage lamination mechanism includes multiple pressure plates 6, each with a first mounting plate 7 on both sides. The outer walls of the multiple first mounting plates 7 are fixedly connected to two front-to-back first ear plates 8. The outer walls of the multiple first ear plates 8 are fixedly connected to sliding sleeves 9 that are slidably connected to limiting rods 5. The outer walls of the multiple first mounting plates 7 are fixedly connected to first sleeves 10. The left and right end faces of the multiple pressure plates 6 are fixedly connected to shafts 11 that are rotatably connected to the first sleeves 10. The outer walls of the multiple first sleeves 10 located on the same side are movably connected to scissor-type telescopic frames 18.

[0027] In this embodiment: the wood to be pressed is placed between multiple pressure plates 6, the hydraulic cylinder 4 is activated, the hydraulic cylinder 4 drives the fixed plate 19 to move downward, and then drives the two uppermost first mounting plates 7 to move downward. The two uppermost first mounting plates 7 further drive the two uppermost first sleeves 10 to move downward, and then drive the uppermost pressure plate 6 to move downward through the connecting shaft 11. When the two uppermost first sleeves 10 move downward, they further drive the multiple lower first sleeves 10 to move downward synchronously through the two scissor-type telescopic frames 18, and then drive the multiple lower pressure plates 6 to move downward synchronously through the connecting shaft 11, thereby pressing multiple pieces of wood simultaneously. Multiple boards can be pressed at one time, resulting in high production efficiency.

[0028] As a technical optimization of this utility model, the flipping mechanism includes a servo motor 16 installed on the upper surface of the top plate 3. The output end of the servo motor 16 extends to the lower part of the top plate 3 and is fixedly connected to a spline shaft 17. A second mounting plate 12 is fixedly connected between two first ear plates 8 located on the left side and at the same height. A second sleeve 14 that is rotatably connected to the spline shaft 17 is rotatably connected to the interior of a plurality of second mounting plates 12. A second bevel gear 15 is fixedly connected to the outer wall of a plurality of second sleeves 14. A first bevel gear 13 that meshes with the second bevel gear 15 is fixedly connected to the outer wall of a plurality of connecting shafts 11 located on the left side.

[0029] In this embodiment: the servo motor 16 is started, and the servo motor 16 drives the spline shaft 17 to rotate, which in turn drives multiple second sleeves 14 to rotate synchronously. The multiple second sleeves 14 further drive multiple second bevel gears 15 to rotate synchronously, which in turn drives multiple first bevel gears 13 to rotate synchronously. The multiple first bevel gears 13 further drive multiple pressure plates 6 to rotate synchronously through the connecting shaft 11, so that the multiple pressure plates 6 rotate synchronously to tilt, thereby causing the wood chips on the upper surface of the pressure plate 6 to automatically slide off under the action of gravity, making it easy to clean the wood chips.

[0030] As a technical optimization of this utility model, a fixing plate 19 is fixedly connected to the upper end face of the two first mounting plates 7 located on the uppermost side, and a hydraulic cylinder 4 is installed on the upper end face of the top plate 3. The output end of the hydraulic cylinder 4 extends to the lower part of the top plate 3 and is fixedly connected to the fixing plate 19.

[0031] In this embodiment, the hydraulic cylinder 4 and the fixed plate 19 work together to facilitate the synchronous up-and-down movement of multiple pressure plates 6 to press the wood.

[0032] As a technical optimization of this utility model, a second ear plate 20 is fixedly connected to the lower side of the right end face of the left support plate 2, and the lower end of the spline shaft 17 is rotatably connected to the second ear plate 20.

[0033] In this embodiment: by rotatably connecting the lower end of the spline shaft 17 to the second ear plate 20, it is convenient to limit the position of the spline shaft 17 and make the spline shaft 17 rotate stably.

[0034] As a technical optimization of this utility model, the lower end of the scissor-type telescopic frame 18 is movably connected to the base plate 1.

[0035] In this embodiment: by movably connecting the lower end of the scissor-type telescopic frame 18 to the base plate 1, it is convenient to limit the lower end of the scissor-type telescopic frame 18 and prevent the scissor-type telescopic frame 18 from moving up and down.

[0036] As a technical optimization of this utility model, a controller is provided on the outer wall of one of the support plates 2, and the hydraulic cylinder 4 and the servo motor 16 are both electrically connected to the controller.

[0037] In this embodiment, the controller facilitates the normal operation of the hydraulic cylinder 4 and the servo motor 16.

[0038] As a technical optimization of this utility model, the servo motor 16 is a worm gear reducer motor.

[0039] In this embodiment, by setting the servo motor 16 as a worm gear reducer motor, it is convenient to use the self-locking property of the worm gear to rotate and fix the spline shaft 17.

[0040] The working principle and usage process of this utility model are as follows: In use, the wood to be pressed is first placed between multiple pressure plates 6. Then, the hydraulic cylinder 4 is activated, causing the fixed plate 19 to move downwards, which in turn causes the two uppermost first mounting plates 7 to move downwards. The two uppermost first mounting plates 7 further cause the two uppermost first sleeves 10 to move downwards, which in turn causes the uppermost pressure plate 6 to move downwards via the connecting shaft 11. As the two uppermost first sleeves 10 move downwards, they further cause the multiple lower first sleeves 10 to move downwards synchronously via the two scissor-type telescopic frames 18, which in turn cause the multiple lower pressure plates 6 to move downwards synchronously via the connecting shaft 11. Simultaneous pressing of multiple pieces of wood allows for the pressing of multiple boards at once, resulting in high production efficiency. After pressing, the hydraulic cylinder 4 drives multiple pressure plates 6 to move upward synchronously, then the boards are removed. The servo motor 16 is then started, which drives the spline shaft 17 to rotate, which in turn drives multiple second sleeves 14 to rotate synchronously. The multiple second sleeves 14 further drive multiple second bevel gears 15 to rotate synchronously, which in turn drives multiple first bevel gears 13 to rotate synchronously. The multiple first bevel gears 13 further drive multiple pressure plates 6 to rotate synchronously through the connecting shaft 11, causing the multiple pressure plates 6 to rotate synchronously to an inclined position. This allows the wood chips on the upper surface of the pressure plates 6 to automatically slide off under gravity, making wood chip cleaning simple.
