Technical Field
[0001] This utility model belongs to the field of wood board cold pressing technology, specifically, it relates to a cold pressing auxiliary device for processing solid wood boards. Background Technology
[0002] The processing of solid wood boards includes raw material cutting, drying, gluing, lamination, cold pressing, hot pressing, painting and edge trimming. In cold pressing, a cold press is used to press the laminated raw materials together. A woodworking cold press is a type of mechanical equipment commonly used in wood processing. It mainly uses pressure to bond multiple pieces of wood together to form a larger wood board. Usually, a forklift is used to move the stacked laminated raw materials to the worktable of the cold press.
[0003] Application No.: CN201921628337.1 (Announcement No.: CN211392832U) Utility Model discloses a feeding trolley for a wood board cold press, including a square base frame and universal wheels with brakes installed at the lower end of the base frame. Two upward support columns are fixed on the upper right side of the base frame, and the upper ends of the two support columns are connected by a crossbeam. Each support column is fitted with a sliding cylinder, and a square support frame arranged horizontally to the left is fixed between the two sliding cylinders. The inner cavity of the support frame is rotatably connected to the front and rear ends of the support frame at equal intervals in the left and right directions with upwardly extending rollers, and the support frame is connected to a lifting power mechanism.
[0004] The existing feeding device is not convenient for adjusting the position of the board. If the board is placed crookedly, it may shift during the feeding process, which may prevent it from entering the cold press. Utility Model Content
[0005] In view of this, the present invention provides a cold pressing auxiliary device for solid wood board processing, which solves the technical problems of existing feeding devices being inconvenient to adjust the position of the boards, the skewness caused by the placement of the boards, and the possible deviation during the feeding process, which may lead to the boards being unable to enter the cold press.
[0006] This utility model is implemented as follows:
[0007] This utility model provides a cold pressing auxiliary equipment for solid wood board processing, which has a movable platform located on the left side of the cold press body. The movable platform is equipped with a support frame, and the right end of the support frame is equipped with a rotating roller rotatably connected to it. The rotating roller is used to drive the solid wood board to move laterally into the cold press.
[0008] The support frame is provided with two synchronously longitudinally moving clamping plates located on the left side of the rotating roller. The clamping plates are in the shape of an inverted "mountain" and are used to position the solid wood board to the transverse center of the support frame.
[0009] Each clamping plate has a corresponding extension plate fixedly installed on its right wall, and the extension plate is slightly higher than the lower worktable of the cold press body.
[0010] Based on the above technical solution, the cold pressing auxiliary equipment for solid wood board processing of this utility model can be further improved as follows:
[0011] Furthermore, threaded blocks are fixedly installed on the bottom wall of the vertical rod in the middle of both clamping plates, and a double-ended screw is rotatably connected to the middle of the support frame in the lateral direction. The threaded blocks are threadedly connected to both ends of the double-ended screw.
[0012] Slider blocks are fixedly installed on the bottom walls of the vertical rods on both sides of the two clamping plates. Two fixed sliding rods are symmetrically installed on the support frame, and the sliders are slidably connected to the sliding rods on the same side.
[0013] Furthermore, the movable ends of the drive cylinders are fixedly installed at the four corners of the bottom wall of the support frame, and the fixed ends of the drive cylinders are fixedly installed on the movable platform.
[0014] Furthermore, the support frame is provided with a plurality of rotatably connected guide rollers, which are arranged symmetrically about the support frame in the longitudinal direction and distributed between two adjacent vertical rods of the clamping plate.
[0015] Furthermore, a through groove is provided between the slide rod on the right and the double-ended lead screw, and a push plate is provided in the through groove. The push plate moves vertically along the through groove and moves laterally along the through groove.
[0016] Furthermore, casters are fixedly installed at the four corners of the bottom wall of the mobile platform, and the casters have locking parts.
[0017] Compared with existing technologies, the advantages of the cold-pressing auxiliary equipment for solid wood board processing provided by this utility model are:
[0018] The height of the sheet metal can be adjusted by setting up a support frame, making it suitable for various cold presses; the equipment is located outside the cold press, and the separate design allows it to be used on multiple cold presses.
[0019] By setting a clamping plate that moves synchronously, the plate can be positioned in the middle and the front and back walls of the plate can be kept flat, thus avoiding displacement during the loading process.
[0020] By setting an extension plate inside the cold press, the plate can be continuously guided until it is fully inside the cold press. The clamping plate allows the plate to be placed on the rotating rollers and guide rollers without the need for manual alignment or movement.
[0021] By setting the extension plate slightly higher than the rotating roller, the rotation of the rotating roller can be avoided.
[0022] By setting up a pusher plate, the distance between the rotating roller and the cold press is avoided, which would prevent the wood board from being fully moved into the cold press. Therefore, a pusher plate that moves laterally is set up to push the board a short distance. The pusher plate can also move longitudinally to avoid affecting the board during the feeding process of the rotating roller. When the pusher plate is not working, it is located below the rotating roller, making the overall structure compact. Attached Figure Description

[0035] Example 1
[0036] like Figure 1-4 As shown, this utility model provides a cold pressing auxiliary equipment for solid wood board processing, which has a movable table 1, the movable table 1 is located on the left side of the cold press body, wherein the movable table 1 is provided with a support frame 11, and the right end of the support frame 11 is provided with a rotating roller 3 rotatably connected, the rotating roller 3 is used to drive the solid wood board to move laterally into the cold press.
[0037] Two clamping plates 2 that move longitudinally in sync are provided on the support frame 11 and located to the left of the rotating roller 3. The clamping plates 2 are in the shape of an inverted "mountain" and are used to position the solid wood board to the middle of the support frame 11 in the transverse direction.
[0038] Each clamping plate 2 has a corresponding extension plate 21 fixedly installed on its right wall. The extension plate 21 is slightly higher than the lower worktable of the cold press body.
[0039] Optionally, in the above technical solution, threaded blocks 22 are fixedly installed on the bottom wall of the vertical rod in the middle of the two clamping plates 2, and a double-ended screw 23 is rotatably connected to the middle of the horizontal part of the support frame 11, with the threaded blocks 22 threadedly connected to both ends of the double-ended screw 23.
[0040] Slider 24 is fixedly installed on the bottom wall of the vertical rods on both sides of the two clamping plates 2. Two fixed sliding rods 25 are symmetrically installed on the support frame 11. The slider 24 is slidably connected to the sliding rod 25 on the same side.
[0041] Optionally, in the above technical solution, the movable ends of the drive cylinders 12 are fixedly installed at the four corners of the bottom wall of the support frame 11, and the fixed ends of the drive cylinders 12 are fixedly installed on the moving platform 1.
[0042] Optionally, in the above technical solution, the support frame 11 is provided with a plurality of rotatably connected guide rollers 31, the guide rollers 31 are arranged symmetrically about the support frame 11 in the longitudinal direction, and the guide rollers 31 are distributed between two adjacent vertical rods of the clamping plate 2.
[0043] Optionally, in the above technical solution, a through groove 40 is provided between the right slide bar 25 and the double-ended lead screw 23, and a push plate 41 is provided in the through groove 40. The push plate 41 moves vertically along the through groove 40 and moves laterally along the through groove 40.
[0044] Optionally, in the above technical solution, casters 5 are fixedly installed at the four corners of the bottom wall of the mobile platform 1, and the casters 5 have locking parts.
[0045] The length and width of the push plate 41 are smaller than the length and width of the through groove 40.
[0046] Among them, the output shaft of drive motor B30 only needs to rotate clockwise, while the output shaft of drive motor A20 can rotate either clockwise or counterclockwise.
[0047] The bottom wall of the extension plate 21 is slightly higher than the top surface of the rotating roller 3 (the height distance between the extension plate 21 and the rotating roller 3 is less than the thickness of the plate), so as to avoid it abutting against the rotating roller 3 and affecting the rotation of the rotating roller 3.
[0048] Among them, multiple "L"-shaped plates are fixedly installed on the support frame 11, and both ends of the rotating roller 3 and the guide roller 31 are rotatably connected to the long plate of the L-shaped plate.
[0049] Preferably, the drive cylinder 12, the telescopic cylinder A42, and the telescopic cylinder B43 are all cylinders with guide rods.
[0050] Furthermore, a drive motor A20 is fixedly installed at the middle of the front end of the support frame 11. The output axis of the drive motor A20 extends rearward and is connected to the double-ended lead screw 23 via a coupling. A drive motor B30 is fixedly installed at the right front end of the support frame 11. The output axis of the drive motor B30 extends rearward and is connected to the rotating roller 3 via a coupling.
[0051] Furthermore, the movable platform 1 is provided with a movable plate 4 that is slidably connected laterally. A telescopic cylinder A42 is fixedly installed on the movable plate 4. The movable end of the telescopic cylinder A42 extends upward and is fixedly connected to the middle of the left end of the push plate 41. A telescopic cylinder B43 is fixedly installed in the middle of the longitudinal direction of the top wall of the movable platform 1. The movable end of the telescopic cylinder B43 extends to the right and its end is fixedly connected to the left wall of the movable plate 4.
[0052] The process of cold pressing wood boards includes: preparing wood boards; adding glue; placing the pressing plate; and applying pressure.
[0053] The purpose of this cold pressing auxiliary equipment is to move the prepared wood boards (stacked) into the cold press after gluing is completed.
[0054] Preferably, a dual-head motor can be installed on the support frame 11 at the left side of the dual-head screw 23 to drive the corresponding two guide rollers 31 to rotate in the same way as the rotating roller 3, thereby providing auxiliary power for the feeding of the rotating roller 3.
[0055] Preferably, multiple rollers are evenly distributed on the extension plate 21 and the clamping plate 2, and the rollers are embedded in the opposite side of the two extension plates 21 and the opposite side of the two clamping plates 2, which facilitates the movement of the plate.
[0056] Preferably, the height of the stacked wooden boards to be cold-pressed adapted to the cold-pressing auxiliary equipment is less than the height of the push plate 41, so as to avoid the wooden boards being not firm after gluing, causing the upper layer of wooden boards on the push plate 41 to separate during the pushing process (if the glue actually used for gluing can guarantee that there will be no separation after gluing, it is not limited by the push plate 41, but it is always limited by the size of the cold press, that is, the length and width of the wooden boards cannot be greater than the size of the upper and lower working platforms of the cold press).
[0057] Working principle:
[0058] When in use, (at this time, the distance between the two clamping plates 2 is the largest, the moving plate 4 is located at the leftmost end of the stroke, the push plate 41 is located at the bottommost end of the stroke, and the height of the support frame 11 is between the upper and lower working platforms of the cold press) place the solid wood board that needs to be cold-pressed onto the rotating roller 3 and the guide roller 31 (depending on the length of the board, it may not need to contact each guide roller 31, but it must contact the rotating roller 3).
[0059] Push the moving table 1 so that its right wall (the side with the rotating roller 3) fits against the side wall of the cold press (the side of the cold press feed port). At this time, the extension plate 21 is inserted into the cold press. First, start the drive cylinder 12 to drive the support frame 11 to move down until the top surface of the rotating roller 3 is flush with the lower working platform of the cold press. At this time, the wooden board to be cold-pressed can be moved smoothly to the lower working platform.
[0060] Then, bring the two clamping plates 2 closer together (the extension plate 21 moves along with them) to position the plate in the middle, making the front and back walls of the plate straight, so as to avoid deviation during the feeding process and prevent it from being unable to move onto the cold press. Then, start the drive motor B30 to make the rotating roller 3 rotate clockwise and move the plate onto the cold press (the extension plate 21 ensures that the plate will not deviate when it is fully moved into the cold press, especially during the process of the push plate 41 pushing the plate into the cold press, it still maintains a straight movement in the transverse direction).
[0061] Start the telescopic cylinder A42 so that its movable end extends and drives the push plate 41 to move upward until the bottom wall of the push plate 41 is higher than the rotating roller 3. Then start the telescopic cylinder B43 so that its movable end extends and drives the push plate 41 on the moving plate 4 to move to the right, pushing the leftmost part of the board that has not entered the cold press completely into the cold press (the board is fed by the aforementioned rotating roller 3, and combined with the push of the telescopic cylinder B43, there is no need to use a cylinder with an excessively long stroke to feed the board. The pushing range is the distance from the inside of the cold press to the rotating roller 3).
[0062] Finally, release the clamping plate 2 and move the moving table 1 backward as a whole until the extension plate 21 is removed from the cold press. Then the cold press can be put into operation to press down the plate (no manual operation is required to avoid getting too close to the cold press and causing danger).
[0063] The synchronous movement of the clamping plate 2 is achieved by activating the drive motor A20 to rotate clockwise or counterclockwise, thereby causing the double-ended lead screw 23 to rotate in place. The threaded blocks 22 on both sides move closer or further apart due to the threaded connection, and the sliding rods 25 on both sides provide guidance for the movement. The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
