Description

Technical Field

[0001] This application relates to the field of dust removal technology for sheet metal, specifically to a dust removal device for sheet metal and a hot pressing device. Background Technology

[0002] In production lines for engineered wood panels, decorative panels, and composite flooring, hot pressing is a crucial process. Before hot pressing, the surface of the substrate often has wood chips, dust, fibers, and even oil stains adhering to it. If these are not cleaned properly, defects such as pitting, blistering, and delamination can easily occur under high temperature and pressure, directly affecting the appearance quality and bonding strength of the finished product. Therefore, the boards are generally equipped with dust removal or cleaning devices before entering the hot pressing station. Currently, the most common method is to install a pair of brush rollers on the upper and lower sides of the conveyor roller conveyor, which remove contaminants from both sides by rotating and brushing.

[0003] In existing technologies, brush rollers are typically mounted on fixed supports. This structure is barely usable when mass-producing sheets of a single thickness, but it reveals significant shortcomings in flexible production scenarios with multiple specifications and small batches. (1) When the board is thin, the contact pressure between the upper and lower brush rollers and the board surface is too small, and the bristles cannot fully cut into the surface gaps, resulting in dust residue and a significant reduction in cleaning effect. (2) When the thickness of the board is large, the fixed spacing cannot accommodate the board to pass through. It is often necessary to stop the machine to disassemble or replace the entire brush mechanism, which increases manual intervention and reduces the overall line speed.

[0004] Therefore, how to enable the dust removal device for boards to adjust the brush roller spacing required for cleaning the boards according to different board thicknesses has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] This application provides a dust removal device and a hot pressing device for sheet metal, which improves the problem that the dust removal device for sheet metal cannot adjust the cleaning distance of the brush roller according to the thickness of the sheet metal.

[0006] In a first aspect, embodiments of this application provide a dust removal device for sheet metal, comprising: Mounting rack; Two dust removal mechanisms are both mounted on the mounting frame, and the two dust removal mechanisms are arranged opposite each other to define the dust removal distance of the board; and Two spacing adjustment mechanisms are provided, one of which is connected to one of the dust removal mechanisms, and the other of which is connected to the other dust removal mechanism, for adjusting the size of the dust removal spacing of the board. The spacing adjustment mechanism includes a force-applying component, two opposing adjustment components, and a transmission component. The force-applying component is connected to the input end of one of the adjustment components and the transmission component. The end of the transmission component away from the force-applying component is connected to the other adjustment component. The adjustment ends of the two adjustment components are connected to the same dust removal mechanism.

[0007] Optionally, the transmission assembly includes a transmission rod and at least two couplings, one end of the transmission rod being connected to the force-applying member via the couplings, and the other end being connected to the adjustment assembly.

[0008] Optionally, the transmission assembly further includes at least one support bearing seat, which is disposed on the mounting bracket and sleeved on the transmission rod.

[0009] Optionally, the dust removal mechanism includes a drive assembly and a cleaning roller. The two ends of the cleaning roller are rotatably connected to the adjustment ends of the two adjustment assemblies, respectively. The drive assembly is disposed on the mounting frame, and the drive end of the drive assembly is connected to one end of the cleaning roller to drive the cleaning roller to rotate.

[0010] Optionally, the cleaning rollers in the two dust removal mechanisms are arranged opposite to each other to define the dust removal distance of the board, and the two cleaning rollers rotate in opposite directions.

[0011] Optionally, the drive assembly includes a drive motor, a drive sprocket, a driven sprocket, and a chain. The drive motor is mounted on the mounting frame, and its output end is connected to the drive sprocket. The driven sprocket is connected to one end of the cleaning roller, and the chain meshes with both the drive sprocket and the driven sprocket.

[0012] Optionally, the drive assembly further includes a reducer, the input end of which is connected to the output end of the drive assembly, and the output end of which is connected to the drive sprocket.

[0013] Optionally, the dust removal mechanism further includes a dust collection frame, a negative pressure pipe, and multiple dust collection nozzles. The dust collection frame is mounted on the mounting frame and forms a dust collection channel. The negative pressure pipe is connected to the dust collection channel and provides negative pressure. The multiple dust collection nozzles are arranged at intervals along the axial direction of the cleaning roller and are all connected to the dust collection channel.

[0014] Optionally, the adjusting component is a screw jack, the input end of which is connected to the force-applying component, and the output end of which is connected to the dust removal mechanism.

[0015] Secondly, embodiments of this application provide a hot pressing device, including the sheet metal dust removal device as described in the first aspect.

[0016] Therefore, the embodiments of this application utilize two spacing adjustment mechanisms to connect two dust removal mechanisms respectively, thereby driving the two dust removal mechanisms to move towards or away from each other. This changes the dust removal distance defined by the two dust removal mechanisms, adapting to boards of different thicknesses. Dust removal of boards of different thicknesses can be achieved simply by adjusting the position of the dust removal mechanisms through the spacing adjustment mechanisms. Specifically, by applying force to the force-applying component in the spacing adjustment assembly, the force-applying component drives one of the adjustment components and the transmission component to move. The transmission component then synchronously transmits the movement of the force-applying component to the other adjustment component, achieving synchronous movement of the two adjustment components. The two adjustment components synchronously drive both ends of the dust removal mechanism, ensuring smooth movement of the dust removal mechanism and thus achieving the purpose of adjusting the dust removal distance of the board according to the board thickness.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or specifying the number of technical features indicated. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0022] Please see Figures 1 to 6 This application provides a dust removal device for sheet metal, including a mounting frame 1, two dust removal mechanisms 2, and two spacing adjustment mechanisms 3. Both dust removal mechanisms 2 are mounted on the mounting frame 1 and are arranged opposite to each other to define the dust removal spacing for the sheet metal. The adjustment end of one spacing adjustment mechanism 3 is connected to one of the dust removal mechanisms 2, and the adjustment end of the other spacing adjustment mechanism 3 is connected to the other dust removal mechanism 2, for adjusting the size of the dust removal spacing for the sheet metal.

[0023] The spacing adjustment mechanism 3 includes a force-applying component 31, two opposing adjustment components 32, and a transmission component 33. The force-applying component 31 is connected to the input end of one of the adjustment components 32 and the transmission component 33. The end of the transmission component 33 away from the force-applying component 31 is connected to the other adjustment component 32. The adjustment ends of the two adjustment components 32 are connected to the same dust removal mechanism 2.

[0024] The technical solution provided in this application utilizes two spacing adjustment mechanisms 3 to connect two dust removal mechanisms 2 respectively, thereby driving the two dust removal mechanisms 2 to move towards or away from each other, thus changing the dust removal distance of the board defined by the two dust removal mechanisms 2. This adapts to boards of different thicknesses, and dust removal of boards of different thicknesses can be achieved simply by adjusting the position of the dust removal mechanisms 2 through the spacing adjustment mechanisms 3. In detail, by applying force to the force-applying member 31 in the spacing adjustment component 32, the force-applying member 31 can drive one of the adjustment components 32 and the transmission component 33 to move. The transmission component 33 then synchronously transmits the movement of the force-applying member 31 to the other adjustment component 32, achieving synchronous movement of the two adjustment components 32. The two adjustment components 32 synchronously drive both ends of the dust removal mechanism 2, ensuring the smooth movement of the dust removal mechanism 2, thereby achieving the purpose of adjusting the dust removal distance of the board according to the thickness of the board.

[0025] In some embodiments, the adjusting component 32 is a screw jack, with its input end connected to the force-applying component 31 and its output end connected to the dust removal mechanism 2. The force-applying component 31 can be a handwheel. The handwheel, in conjunction with the screw jack, constitutes a handwheel-type screw jack. Screw jacks are existing products. In this embodiment, the screw jack used is a product of Shanghai Yintong, model SJA50, of the screw motion type, and its core principle is a worm gear structure.

[0026] In some embodiments, see Figure 2 and Figure 6 The transmission assembly 33 includes a transmission rod 331 and at least two couplings 332. One end of the transmission rod 331 is connected to the force-applying component 31 via the coupling 332, and the other end is connected to the adjusting component 32. When the operator applies force to the force-applying component 31, the force-applying component 31 transmits the force and the motion to the transmission rod 331 and one of the adjusting components 32 that are connected to the force-applying component 31, causing the transmission rod 331 and the adjusting component 32 to move synchronously. At the same time, the transmission rod 331 also drives the adjusting component 32 on the side away from the force-applying component 31 to move synchronously. The two adjusting components 32 synchronously drive the dust removal mechanism 2, achieving stable movement of the dust removal mechanism 2. In this embodiment, the force-applying component 31 undergoes rotational motion, which in turn drives the transmission rod 331 to rotate. The rotational motion of the force-applying component 31 is also transmitted to one of the adjustment components 32, causing the adjustment end of the adjustment component 32 to move linearly. The transmission rod 331 also drives the other adjustment component 32 to move linearly, so that the two adjustment components 32 move linearly toward or away from the dust removal mechanism 2 in sync, thereby achieving the purpose of changing the dust removal distance between the two dust removal mechanisms 2.

[0027] Furthermore, the transmission assembly 33 also includes at least one support bearing seat 333, which is disposed on the mounting bracket 1 and sleeved on the transmission rod 331, serving to support the transmission rod 331 and stabilize its rotation. For example, for a long transmission rod 331, it is easily affected by deflection and may bend, leading to unstable rotation. By providing multiple support bearing seats 333, multiple supports are formed in the axial direction of the transmission rod 331, thereby effectively overcoming the bending deformation of the transmission rod 331 caused by deflection.

[0028] In some embodiments, see Figures 3 to 5The dust removal mechanism 2 includes a drive assembly 21 and a cleaning roller 22. Both ends of the cleaning roller 22 are rotatably connected to the adjustment ends of two adjustment assemblies 32, respectively. The drive assembly 21 is mounted on the mounting frame 1, and its drive end is connected to one end of the cleaning roller 22 to drive its rotation. By using the drive assembly 21 to drive the cleaning roller 22 to rotate, when the board enters the dust removal gap defined by the two cleaning rollers 22, the rotation of the cleaning roller 22 can sweep away dust, waste residue, and debris from the surface of the board. Some of this debris will be adsorbed onto the surface of the cleaning roller 22, some will be swept away from the board surface, and some will be swept from the rear end to the front end. The direction from the rear end to the front end is the direction of board conveying. The adjustment end of the adjustment assembly 32 is connected to the cleaning roller 22, thus realizing the adjustment of the gap between the two cleaning rollers 22. In this embodiment, the adjustment direction is the up-and-down lifting direction. Furthermore, the two ends of the cleaning roller 22 are rotatably connected to the adjustment end, ensuring the normal rotation of the cleaning roller 22.

[0029] Furthermore, the cleaning rollers 22 in the two dust removal mechanisms 2 are arranged opposite to each other to define the dust removal distance of the board, and the two cleaning rollers 22 rotate in opposite directions. By setting the rotation directions of the two cleaning rollers 22 to be opposite, it is beneficial to assist in the transportation of the board. In addition, the size of the board dust removal distance defined by the two cleaning rollers 22 is mainly determined according to the thickness of the board, and generally the board dust removal distance is slightly smaller than the thickness of the board to ensure that the cleaning rollers 22 can form a squeezing cleaning on the board. For example, the board dust removal distance can be equal to 0.95 times the thickness of the board.

[0030] In some embodiments, see Figure 4 The drive assembly 21 includes a drive motor 211, a drive sprocket 212, a driven sprocket 213, and a chain 214. The drive motor 211 is mounted on the mounting frame 1, and its output end is connected to the drive sprocket 212. The driven sprocket 213 is connected to one end of the cleaning roller 22. The chain 214 meshes with both the drive sprocket 212 and the driven sprocket 213. When the drive motor 211 starts, it drives the drive sprocket 212 to rotate. The rotation of the drive sprocket 212 is transmitted to the driven sprocket 213 through the chain 214, causing the driven sprocket 213 to rotate synchronously. The driven sprocket 213 is fitted onto the cleaning roller 22, thereby synchronously driving the cleaning roller 22 to rotate.

[0031] Furthermore, the drive assembly 21 also includes a reducer 215. The input end of the reducer 215 is connected to the output end of the drive assembly 21, and the output end of the reducer 215 is connected to the drive sprocket 212. This reduces the rotational speed of the drive motor 211, making the rotational speed of the cleaning roller 22 easier to control. For example, the reduction ratio of the reducer 215 can be 1:10, or it can be another reduction ratio, set according to actual needs.

[0032] In some embodiments, see Figure 5 The dust removal mechanism 2 also includes a dust collection frame 23, a negative pressure pipe 24, and multiple suction nozzles 25. The dust collection frame 23 is mounted on the mounting frame 1 and forms a suction channel. The negative pressure pipe 24 is connected to the suction channel and provides negative pressure. The multiple suction nozzles 25 are arranged at intervals along the axial direction of the cleaning roller 22 and are all connected to the suction channel. The negative pressure pipe 24 provides negative pressure mainly through an externally connected negative pressure device, which provides negative pressure, and then the negative pressure is transmitted to the suction channel connected to it through the negative pressure pipe 24. By using multiple suction nozzles 25 to absorb dust and other dirt, the cleaning effect is further improved.

[0033] Furthermore, the suction nozzle 25 is located on the side of the cleaning roller 22 facing its direction of travel, which helps to improve the cleaning effect of the suction nozzle 25 on the dirt swept out by the rotating cleaning roller 22.

[0034] Embodiments of this application also provide a hot pressing device, including the sheet metal dust removal device described in any of the foregoing embodiments. Since the hot pressing device includes a sheet metal dust removal device, all aspects of the structure and beneficial effects of such a device are present in the hot pressing device and will not be elaborated further here.
