Description

Technical Field

[0001] This utility model belongs to the technical field of sheet metal production equipment, and in particular relates to a dust removal mechanism for a pre-adhesive coating process on sheet metal surfaces. Background Technology

[0002] In the field of board processing, the quality of the surface gluing process directly determines the stability of subsequent board splicing, lamination and other processes. The effectiveness of pre-dust removal is the core prerequisite affecting the quality of gluing. If wood chips, dust and other impurities remain on the board surface, gaps will appear between the glue layer and the board surface, which will lead to defects such as delamination and bubbling. In severe cases, rework is required, which will significantly increase production costs.

[0003] Currently, the mainstream pre-dust removal method for boards in the industry mainly adopts a blowing or suction structure with fixed nozzles to remove surface dust through airflow impact or adsorption. However, the existing technology has a key problem that is easily overlooked and difficult to solve: although the existing dust removal structure can quickly remove some surface dust, it is powerless against residual dust in the grooves of the board surface and dust with strong adsorption, making it difficult for the existing dust removal mechanism to meet the pre-cleaning requirements of high-precision board gluing process. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing pre-dust removal methods for boards using fixed nozzle blowing or suction structures can only quickly remove a portion of the surface dust, but cannot effectively remove residual dust in the textured depressions of the board surface or dust with strong adsorption. Therefore, this invention provides a dust removal mechanism for the pre-adhesion process on the board surface.

[0005] The present invention achieves the above objectives through the following technical solution: a dust removal mechanism for a pre-adhesive coating process on a board surface, comprising a board conveying device, wherein a dust removal component is provided at one end of the upper surface of the board conveying device; The dust removal assembly includes a support arm fixed to the upper surface of the plate conveying device. A dust removal mechanism is provided on the support arm. A protective cover is provided on the support arm located outside the dust removal mechanism. A plurality of serpentine air ducts are evenly distributed on one side wall of the protective cover. The air outlets of the serpentine air ducts cooperate with the dust removal mechanism. The dust removal mechanism includes a dust removal body fixed to the support arm. Two sets of bearing seats are arranged opposite each other at both ends of the dust removal body. A drive shaft is arranged between the inner rings of the two sets of bearing seats located at the same end. A gear plate is fixedly arranged on each of the two sets of drive shafts. The two sets of gear plates are connected by a chain belt. A motor that rotates one of the drive shafts is arranged on the outer wall of one end of the dust removal body. Several sets of extension arms are evenly distributed on the outer wall of the chain belt. A cleaning head is arranged at the end of each extension arm.

[0006] Furthermore, the sheet material conveying device includes a conveyor frame, with conveyor rollers rotatably mounted at both ends of the conveyor frame, a conveyor belt sleeved between the two sets of conveyor rollers, and a drive motor mounted on one side of the conveyor frame. The output shaft of the drive motor is fixedly connected to one end of one set of conveyor rollers via a coupling.

[0007] Furthermore, a reinforcing seat is provided between the extension arm and the outer side wall of the chain belt, and the extension arm is L-shaped.

[0008] Furthermore, the cleaning head includes a mounting base fixedly connected to the end of the extension arm, and the surface of the mounting base is covered with cleaning bristles.

[0009] Furthermore, an observation window is provided on the other side wall of the protective cover away from the serpentine duct, and the observation window is fitted with transparent glass.

[0010] Furthermore, the snake-neck duct includes a flexible metal corrugated pipe, one end of which is connected to an external air supply duct, and the other end of which is provided with a conical air outlet.

[0011] Beneficial effects: This utility model has a reasonable design, simple and stable structure, and strong practicality, and has the following beneficial effects: Enhancing dust removal thoroughness: This dust removal mechanism uses a motor to drive the drive shaft, gear plate, and chain belt to rotate, which in turn drives the cleaning head at the end of the extension arm to dynamically sweep the surface of the board. This effectively removes residual dust and strongly adsorbed dust from the textured depressions on the board surface. At the same time, the snake-neck duct on the side wall of the protective cover adopts a flexible metal corrugated pipe structure, which can flexibly adjust the angle and position of the conical air outlet to precisely match the sweeping trajectory of the cleaning head. This allows the dust raised by the sweeping to be blown to the designated area or directly discharged, avoiding secondary dust dispersion and re-contamination, and ensuring the cleanliness of the board surface to meet the requirements of high-precision gluing. Balancing the compatibility with sheet material specifications and cleaning stability: The extension arm is designed in an "L" shape and reinforced with a seat between it and the chain belt. This enhances the structural strength of the connection between the extension arm and the chain belt, preventing the cleaning head from loosening or shifting due to long-term high-frequency sweeping. The "L" shape also allows for the cleaning needs of sheets of a certain thickness. Meanwhile, the cleaning head uses a mounting base with cleaning bristles. The bristle material ensures cleaning intensity on the sheet material surface while avoiding scratches, effectively balancing cleaning effect and sheet material protection. It can be adapted to dust removal operations on sheets of different thicknesses. Improving the ease of operation and maintenance: The protective cover is equipped with an observation window with transparent glass on the side wall, allowing staff to observe the cleaning status inside the dust removal mechanism and the conveying of the sheet metal in real time, making it easier to detect and handle abnormalities in a timely manner. In addition, the flexible characteristics of the serpentine duct and the sleeve structure of the cleaning head make it easier to adjust the duct angle and replace the cleaning lint, reducing the difficulty and cost of daily equipment maintenance and improving the overall ease of use and operation and maintenance efficiency of the equipment.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Example 1: Combination Figure 1-3 The dust removal mechanism shown includes a board conveying device 1 for automated board conveying. The board conveying device 1 serves as the basic supporting structure of the entire dust removal mechanism. Its core function is to stably convey the board to be dusted to the dust removal operation area, providing continuous and precise material conveying support for subsequent dust removal processes. In order to clean the dust on the board surface during the conveying process, a dust removal component 2 for performing dust removal operations is fixedly installed at one end of the upper surface of the board conveying device 1. The working area of ​​the dust removal component 2 corresponds precisely to the conveying path of the board conveying device 1, ensuring that the board can completely pass through the cleaning range of the dust removal component 2 during the conveying process. The dust removal assembly 2 includes a support arm 201 bolted to the upper surface of the plate conveying device 1. The support arm 201 is made of high-strength metal, and its two ends are fixedly connected to the two side edges of the plate conveying device 1, forming a stable portal support structure. Below the middle crossbeam of the support arm 201, a dust removal mechanism 202 for direct contact with the plate surface is fixedly installed by welding or bolting. The working height of the dust removal mechanism 202 can be preset according to the plate thickness to ensure effective contact between its cleaning end and the plate surface. To prevent dust from spreading to the surrounding environment during dust removal and to protect the dust removal mechanism 202, the support arm 201 located outside the dust removal mechanism 202 is secured with clips or screws. A semi-enclosed protective cover 203 is fixedly installed. The bottom of the protective cover 203 and the surface of the conveyor belt of the board conveying device 1 are reserved with a gap for the board to pass through. In addition, on the side wall of the protective cover 203 facing the cleaning direction of the dust removal mechanism 202, a number of snake neck air ducts 204 are evenly distributed in the horizontal direction. The air outlets of the snake neck air ducts 204 face the cleaning operation point of the dust removal mechanism 202. The angle and height of the air outlets can be flexibly adjusted through the snake neck structure so that the air outlets and the cleaning action of the dust removal mechanism 202 can be coordinated in real time. When the dust removal mechanism 202 sweeps and cleans the surface of the board, the snake neck air ducts 204 can simultaneously suck away or blow away the dust raised by the sweeping to the designated collection area to prevent the dust from falling back onto the surface of the board. The dust removal mechanism 202 includes a dust removal body 2021 bolted to the lower part of the crossbeam in the middle of the support arm 201. The dust removal body 2021 has a long, rectangular frame structure, the length of which is adapted to the conveying width of the plate conveying device 1. At both ends of the dust removal body 2021 along its length, two sets of bearing seats 2022 are respectively and symmetrically fixed to the upper and lower sides of both ends of the dust removal body 2021. The inner ring axes of the bearings of the two sets of bearing seats 2022 at the same end are kept coaxial. Between the inner rings of the bearings of the two sets of bearing seats 2022 at the same end, a drive shaft 202 for transmitting power is provided with an interference fit. 3. Both ends of the drive shaft 2023 pass through the inner rings of the bearings in the two sets of bearing housings 2022, and its ends extend outward from the outer side of the bearing housings 2022, forming a power input or transmission connection end. On the side walls of both sets of drive shafts 2023, a gear disc 2024 is fixedly installed by a flat key. The number of teeth and tooth pitch of the two sets of gear discs 2024 are consistent. The two sets of gear discs 2024 are meshed with a chain belt 2025 that matches the tooth pitch of the gear discs 2024, forming a closed-loop transmission structure. When one set of drive shafts 2023 rotates, the meshing transmission between the gear disc 2024 and the chain belt 2025 drives the other set of drive shafts 2023 to rotate synchronously. The chain belt 2025 is driven by a motor bracket, which provides power to the drive shaft 2023. The motor 2026, located on the outer wall of one end of the dust collector body 2021, rotates one of the drive shafts 2023. The output shaft of the motor 2026 is fixedly connected to the end of the drive shaft 2023 extending from the bearing housing 2022 via a coupling. When the motor 2026 is energized, the torque of its output shaft is transmitted to the drive shaft 2023 via the coupling, thereby driving the entire chain belt 2025 transmission structure. The chain belt 2025 rotates along its cyclic movement direction on the outer wall of the chain belt 2025. Several sets of extended arms 2027 are evenly distributed. The extended arms 2027 are fixedly connected to the chain links of the chain belt 2025 by welding or bolts, and the extension direction of all extended arms 2027 is consistent. At the end of each extended arm 2027, a cleaning head 2028 for directly cleaning the surface of the board is detachably connected by threads or buckles. The cleaning head 2028 is made of soft and wear-resistant cleaning material. When the chain belt 2025 drives the extended arms 2027 to circulate, the cleaning head 2028 can move synchronously with the extended arms 2027 to continuously sweep and clean the surface of the board conveyed below, realizing dust removal operation.

[0016] In this embodiment, the sheet metal conveying device 1 includes a conveyor frame 101, which serves as the basic load-bearing frame of the entire conveying structure. The conveyor frame 101 is welded from rectangular steel pipes. At both ends of the conveyor frame 101 along its length, conveyor rollers 102 are rotatably mounted via bearing seats. A conveyor belt 103 is sleeved between the two sets of conveyor rollers 102 for directly carrying and conveying the sheet metal. When the conveyor rollers 102 rotate, friction drives the conveyor belt 103 to circulate along the conveying direction, thereby achieving stable conveying of the sheet metal placed on the upper surface of the conveyor belt 103. To provide the conveyor rollers 102 with… The rotational power is provided by a drive motor 104 fixedly mounted on one side wall of the conveyor frame 101 via a motor mounting bracket. The drive motor 104 is a geared motor, and its output speed can be adjusted according to the dust removal requirements of the board, ensuring that the board maintains a suitable conveying speed when passing through the working area of ​​the dust removal component 2, providing sufficient cleaning time for the dust removal mechanism 202. The output shaft of the drive motor 104 is fixedly connected to one end of one set of conveyor rollers 102 via a flexible coupling to avoid damage to the conveyor rollers 102 or the motor output shaft due to excessive torque.

[0017] In this embodiment, to ensure the structural stability of the extension arm 2027 when driving the cleaning head 2028 to perform dust removal operations, and to avoid loosening or breakage of the connection between the extension arm 2027 and the chain belt 2025 due to long-term high-frequency sweeping, a reinforcing seat is integrally formed or fixed by welding between the outer walls of the extension arm 2027 and the chain belt 2025 to enhance the connection strength. At the same time, to adapt to the working space layout of the dust removal mechanism 202 and to ensure that the cleaning head 2028 can accurately contact the surface of the plate and avoid interference from other components, the shape of the extension arm 2027 is designed as "L".

[0018] In this embodiment, the cleaning head 2028 includes a mounting base for achieving a stable connection with the extension arm 2027. On the cylindrical protruding surface of the mounting base, cleaning bristles for directly contacting the surface of the board to remove dust are tightly fitted. The cleaning bristles are made of highly elastic and wear-resistant nylon fibers or microfibers. The fibers of the bristles are distributed in a fluffy manner. When in contact with the surface of the board, they can remove dust through the sweeping action of the fibers and temporarily adsorb dust through the gaps between the fibers, preventing the dust from being raised again during the cleaning process. The dust is then carried away by the airflow of the subsequent serpentine duct 204, thereby improving the overall dust removal effect.

[0019] In this embodiment, in order to realize real-time monitoring of the operation status of the dust removal mechanism 202 and facilitate the timely detection of abnormalities such as deviation of plate conveying, wear of cleaning head 2028, or dust accumulation by the staff, an observation window for observing the internal working conditions is opened on the other side wall of the protective cover 203 away from the snake neck duct (204). A transparent glass is fixedly installed in the observation window, and the staff can clearly observe the internal working conditions through the glass. The dust removal operation status can be grasped without opening the protective cover 203, which not only ensures the dust removal efficiency, but also reduces the dust leakage problem caused by frequent opening of the protective cover 203.

[0020] In this embodiment, the serpentine duct 204 includes a flexible metal corrugated pipe for flexible angle adjustment. The flexible metal corrugated pipe is formed by spiral winding of multiple layers of stainless steel strips, and metal reinforcing ribs are provided inside the pipe wall. This ensures the flexibility of the corrugated pipe to bend and shape arbitrarily within a 360° range, and can also resist the deformation of the pipe wall caused by airflow pressure during air supply, ensuring stable airflow delivery. To achieve a stable airflow supply, one end of the flexible metal corrugated pipe is sealed to the external air supply duct through a flange joint. To enhance the airflow, the other end of the flexible metal corrugated pipe is provided with a conical air outlet, which can transform the columnar airflow in the corrugated pipe into a more concentrated conical airflow, reduce the airflow range, increase the local airflow speed, and ensure that the airflow can accurately act on the area swept by the cleaning head 2028 to sweep up the dust.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
