Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically to a mechanical pressing assembly with adjustable thickness. Background Technology

[0002] Trimming and sawing the edges of planks is an important step in wood processing. Its main purpose is to remove irregular parts from the edges of the planks, ensuring that the edges are flat and smooth, and meet the specified dimensions and aesthetic requirements.

[0003] To ensure maximum utilization of the wood planks during edge trimming, a visual recognition system is typically used to trim the opposite sides of the planks to maximize their utilization. Therefore, the planks need to be fed forward one by one, and a pressure assembly is needed to press the planks together during the sawing process.

[0004] For example, the patent publication number CN117901214A discloses "a plate edge cleaning device and method", which includes a correction mechanism. The correction mechanism includes: a base, a correction slide rail, a correction slider, a correction motor, a lead screw, two brackets, a curved arm, a correction cylinder lower block and an upper block. When the output shaft of the correction cylinder is pushed out, the plate to be cleaned is clamped between the lower block and the upper block. The bottom wall of the lower block is flush with the top wall of the plate to be cleaned.

[0005] The device's correction mechanism adopts a single-point structure. The extension and retraction of the correction cylinder drives the crank arm to rotate, thereby pressing or releasing the lower pressure block. However, it can only be applied to a single thickness of wood board. When the thickness of the wood board changes, it cannot guarantee that the bottom wall of the lower pressure block and the top wall of the board to be cleaned are flush.

[0006] Furthermore, using a cylinder to press down the wood conveyor can easily lead to unstable air pressure, which can cause the material to deviate from its intended path. The cylinder is also susceptible to weather conditions, and extremely cold weather can freeze the pneumatic components. Utility Model Content

[0007] The purpose of this invention is to provide a mechanical pressing assembly with adjustable thickness to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An adjustable-thickness mechanical pressing assembly for edge trimming of wood boards includes:

[0010] A movable base and a lead screw drive assembly that drives the movable base to move in a first direction;

[0011] The movable base is provided with two sets of first motors, as well as a first connecting plate and a second connecting plate that move in the second direction. The output ends of the two sets of first motors are respectively provided with a support plate gear and a pressure plate gear. The first connecting plate and the second connecting plate are respectively provided with a support plate rack and a pressure plate rack extending in their moving direction. The support plate rack meshes with the support plate gear, and the pressure plate gear meshes with the pressure plate rack.

[0012] The pallet rack is provided with a pallet plate, and the pressure plate rack is provided with a pressure plate;

[0013] The first direction and the second direction are perpendicular to each other.

[0014] Preferably, the lead screw drive assembly includes a guide rail base, a guide rail and a lead screw disposed on the guide rail base, the lead screw is driven by a second motor, the movable base is mounted on a slider, and the slider slides on the guide rail.

[0015] Preferably, a lead screw protective sleeve is provided on the outside of the lead screw.

[0016] Preferably, the first connecting plate and the second connecting plate slide together on the movable base via a slider rail assembly.

[0017] Preferably, the first motor is a servo motor.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] The first motor uses servo control, which ensures high precision in the pressing method and prevents malfunctions. The mechanical gear and rack transmission method is not easily damaged, is stable, simple, and efficient, and offers high speed and precision, reducing after-sales costs and simplifying installation.

[0020] The mechanical pressing method replaces the cylinder pressing method, which is stable and efficient.

[0021] The use of a gear and rack clamping method prevents material movement, and the upper and lower gears and racks clamp the material stably to prevent it from deviating from its intended direction.

[0022] The pallet and pressure plate clamp the plates by moving in a straight line, which keeps the plates of different thicknesses flush with the side wall of the plates to be cleaned, thus improving clamping stability. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Example: A mechanical pressing assembly with adjustable thickness, such as Figure 1-2 As shown:

[0029] The system includes a fixed guide rail base 2, a guide rail 3 fixed on the guide rail base 2, and a lead screw 8 rotatably connected to the guide rail base 2 via a bearing 1. A servo connector 9 is fixed to one side of the guide rail base 2, and a second motor 10 is installed on the servo connector 9. The second motor 10 is a servo motor. One end of the lead screw 8 and the output end of the second motor 10 are connected by a coupling 6. A second slider 5 is slidably connected to the guide rail 3. A movable base 4 is fixed to the top wall of the second slider 5, and the movable base 4 and the lead screw 8 are threaded together. A lead screw protective sleeve 7 is fitted on the outside of the lead screw 8.

[0030] The movable base 4 has a first connecting plate 11 and a second connecting plate 22 that are slidably connected up and down on one side via a slider rail assembly. The slider rail assembly includes a first guide rail 20 and a first slider 21; the second connecting plate 22 is located above the first connecting plate 11.

[0031] A vertically extending support rack 12 is fixedly provided on one side of the first connecting plate 11, and a vertically extending pressure rack 19 is fixedly provided on one side of the second connecting plate 22.

[0032] Two sets of first motors 16 are fixedly installed on one side of the mobile base 4. The first motors 16 are servo motors, permanent magnet motors, stepper motors, magnetic eddy current brake motors, variable speed motors, or geared motors, etc. The output end of one set of first motors 16 is connected to the support plate gear 13 through a reducer 17, and the support plate gear 13 meshes with the support plate rack 12; the output end of the other set of first motors 16 is connected to the pressure plate gear 18 through a reducer 17, and the pressure plate gear 18 meshes with the pressure plate rack 19.

[0033] A support plate 14 is fixedly installed on the upper end of the support plate rack 12, and a pressure plate 15 is fixedly installed on the upper end of the pressure plate rack 19. The pressure plate 15 is located directly above the support plate 14.

[0034] Working principle:

[0035] During the forward conveying of the sheet material, in order to avoid the pressure plate 15 and the pallet 14 affecting the movement of the sheet material, the pressure plate 15 and the pallet 14 are positioned below the horizontal plane of the sheet material.

[0036] When clamping is required, a set of first motors 16 drives the pressure plate 15 to move upward through the cooperation of the pressure plate gear 18 and the pressure plate rack 19, so that it is positioned above the horizontal plane of the plate.

[0037] Another set of first motors 16 drives the pallet 14 to move upward through the cooperation of pallet gear 13 and pallet rack 12. At this time, the upper surface of the pallet 14 is flush with the lower surface of the plate.

[0038] The plate is then conveyed forward to the space between the upper surface of the pallet 14 and the lower surface of the pressure plate 15. The pressure plate 15 moves downward and clamps the plate with the pallet 14.

[0039] Then the second motor 10 drives the lead screw 8 to rotate, and the rotation of the lead screw 8 drives the clamped plate forward to the position to be sawed through the moving base 4.

[0040] The mechanical pressing assembly is set in two sets. The two sets of mechanical pressing assemblies clamp the two ends of the plate respectively. The two sets of mechanical pressing assemblies are independent of each other. The two sets of mechanical pressing assemblies drive the clamped plate forward to different positions to achieve the correction of the plate.
