Description

Technical Field

[0001] This utility model relates to the field of panel processing technology, and in particular to an adaptive dust collection device for panels in a conveying system. Background Technology

[0002] With the increasing market demand for panel furniture, manufacturers are placing greater emphasis on production efficiency, and modular design and automated integrated production lines have become an industry trend. Automated production lines utilize the coordinated operation of equipment such as roller conveyors, gantry cranes, or robotic arms to achieve the transfer and positioning of panels between various processes, ultimately realizing continuous production from raw wood board loading to finished pre-assembled parts unloading. However, existing automated production lines generally face a technical challenge: after processing by intelligent panel saws or CNC drilling machines, the surface of the panels often retains residual wood chips and dust. These residues can interfere with the subsequent adsorption and gripping operations of robotic arms, especially during the finished product unloading and stacking process, where debris trapped between panels can easily scratch the surface during transportation, affecting product quality.

[0003] To address this issue, common practices currently available include increasing the power of vacuum cleaners to enhance suction, installing air nozzles on the conveyor belt to disperse dust from the board surface, or performing manual cleaning at the end of the production line. However, these methods all have significant limitations: increasing vacuum cleaner power is energy-intensive and still fails to completely remove debris; direct air blowing easily leads to dust dispersion, polluting the working environment and failing to meet environmental protection requirements; and manual intervention is inefficient and increases labor costs. Therefore, existing dust removal methods only address the symptoms, not the root cause, and cannot simultaneously ensure board surface cleanliness while also achieving energy efficiency and environmental protection.

[0004] To address the aforementioned issues, there is an urgent need for a high-efficiency, adaptive, energy-saving, and environmentally friendly dust collection device that can be integrated into a roller conveyor to achieve precise dust removal for boards of different specifications, thereby improving the reliability and cleanliness of automated production. Utility Model Content

[0005] This invention provides an adaptive dust collection device for a conveying system, which can solve the problem that existing dust removal methods mentioned in the background art are only treating the symptoms and not the root cause, and are difficult to ensure the cleanliness of the board surface while taking into account energy efficiency and environmental protection.

[0006] An adaptive dust collection device for a conveying system is used for dust removal on the surface of a roller feeder. It includes a support frame, a dust collection hood component, and a lifting adjustment mechanism and a negative pressure dust collection mechanism disposed on the support frame. The support frame is fixedly installed on the roller feeder, and the lifting adjustment mechanism is installed on the support frame. The lifting and adjusting mechanism is connected to the dust hood component, and the lifting and adjusting mechanism includes a lifting assembly for coarsely adjusting the overall height of the dust hood component and a three-axis cylinder for driving the dust hood component to perform a single dust suction operation reciprocating motion; wherein, the interior of the dust hood component is divided into multiple independent dust suction areas; the negative pressure dust suction mechanism is mounted on the support frame, and it includes a main dust suction cylinder and multiple branch pipes, each branch pipe being connected to a dust suction area of ​​the dust hood component, and each branch pipe is equipped with a control component.

[0007] Preferably, the lifting assembly includes a mounting plate, an adjusting screw, an adjusting nut, a handwheel, and a lifting bracket. The mounting plate is mounted on a support frame. The adjusting screw is rotatably connected to the mounting plate via a bearing. The adjusting nut is threaded onto the adjusting screw. The handwheel is connected to the driving end of the adjusting screw. The adjusting nut is connected to the lifting bracket via a connecting plate. A three-axis cylinder is mounted on one side of the lifting bracket.

[0008] Preferably, the lifting bracket is provided with a limiting cylinder on its side, and a limiting rod connected to the dust collection hood component is slidably connected inside the limiting cylinder.

[0009] Preferably, the dust hood component includes a hood body, partitions, and an exhaust pipe. The hood body has multiple dust collection chambers formed inside by multiple partitions.

[0014] Preferably, the support frame is fixedly installed on the roller feed table by its bottom legs and connecting angle iron.

[0015] Preferably, an electrical control box is provided on one side of the support frame.

[0016] The beneficial effects of this utility model are: In this conveying system, the overall height of the dust collection hood component can be precisely adjusted via a lifting assembly, stably adapting to panel furniture boards of varying thicknesses. A three-axis cylinder drives the dust collection hood component in a single reciprocating motion for each dust collection operation, flexibly avoiding panels lifted by bristle brushes in the roller feeder.

Detailed Implementation

[0019] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0020] like Figure 1-3 As shown, this utility model proposes a panel adaptive dust collection device in a conveying system for dust removal on the panel surface of a roller feeder 2. It includes: a support frame 1, a dust collection hood component 4, and a lifting adjustment mechanism 3 and a negative pressure dust collection mechanism 5 mounted on the support frame 1. The support frame 1 is fixedly installed on the roller feeder 2, and the lifting adjustment mechanism 3 is installed on the support frame 1. The lifting adjustment mechanism 3 includes a lifting component 31 for coarsely adjusting the overall height of the dust collection hood component 4 and a three-axis cylinder 32 for driving the dust collection hood component 4 to perform a single dust collection operation reciprocating motion. The dust collection hood component 4 is internally divided into multiple independent dust collection areas. The negative pressure dust collection mechanism 5 includes a main dust collection cylinder 51 and multiple branch pipes 52, each branch pipe 52 correspondingly connected to a dust collection area of ​​the dust collection hood component 4, and each branch pipe 52 is equipped with a control component 53.

[0021] In the technical solution of this utility model, the overall height of the dust collection hood component 4 can be precisely adjusted by the lifting component 31, which can stably adapt to board furniture boards of different thicknesses, greatly reducing downtime for adjustment. The three-axis cylinder 32 drives the dust collection hood component 4 to perform a single dust collection operation reciprocating motion, which can flexibly avoid the boards lifted by the bristle brush in the roller feeding table 2. The dust collection hood is automatically driven to descend and fit the board surface by the three-axis cylinder 32. After the board leaves, it is automatically lifted and reset, and the height adaptation can be completed without manual intervention. The dust collection hood component 4 is divided into multiple independent dust collection areas. Each branch pipe 52 is connected to a corresponding dust collection area, and each pipe is equipped with a control component 53. The control component 53 can quickly close the dust collection channel of the pipe, leaving only the channel of the board area open. The adaptive board width adjustment method can adapt to the surface dust removal work of most specifications of boards in the automated line. The dust collection hood automatically opens and closes the corresponding area of ​​the dust collection hood according to the width of the board, reducing energy waste and ensuring maximum dust collection efficiency.

[0022] Specifically, the width of the board is identified from the board width information in the front-end host processing file, and the opening and closing of each channel is uniformly controlled by the integrated control system.

[0023] like Figure 1 and Figure 3 As shown, the lifting assembly 31 includes a mounting plate 311, an adjusting screw 312, an adjusting nut 313, a handwheel 314, and a lifting bracket 316. The mounting plate 311 is mounted on the support frame 1. The adjusting screw 312 is rotatably connected to the mounting plate 311 via a bearing. The adjusting screw 312 is threadedly connected to the adjusting nut 313. The drive end of the adjusting screw 312 is connected to the handwheel 314. The adjusting nut 313 is connected to the lifting bracket 316 via a connecting plate 315. A three-axis cylinder 32 is mounted on one side of the lifting bracket 316. By rotating the handwheel 314, the adjusting screw 312 can be rotated on the mounting plate 311. The rotation of the adjusting screw 312 can drive the adjusting nut 313 and the connecting plate 315 to rise and fall, thereby driving the lifting bracket 316 and the dust collection hood component 4 to rise and fall, allowing for precise adjustment of the overall height of the dust collection hood component 4.

[0024] Specifically, when the handwheel 314 is turned, the rotation of the lead screw is converted into the linear lifting and lowering of the adjusting nut 313. Each turn of the handwheel can achieve a height adjustment of 0.5~1mm, which can accurately match the height requirements of different batches of boards within the range of 9~60mm board thickness, ensuring that the dust collection hood and the board surface always maintain the optimal dust removal distance.

[0025] The lifting bracket 316 has a limiting cylinder 33 on its side. The limiting cylinder 33 has a limiting rod 34 that is slidably connected to the dust hood component 4. The lifting bracket 316 is slidably connected to the slide rail 36 on the support frame 1 through the sliding plate 35. The limiting cylinder 33 and the limiting rod 34 cooperate to enhance the stability of the lifting of the dust hood component 4. The sliding plate 35 and the slide rail 36 cooperate to enhance the stability of the lifting of the lifting bracket 316.

[0026] like Figure 1 and Figure 4 As shown, the dust hood component 4 includes a hood body 41, partitions 42, and an exhaust pipe 44. The hood body 41 has multiple dust collection chambers 43 formed inside by multiple partitions 42. Each dust collection chamber 43 is equipped with an exhaust pipe 44, and each exhaust pipe 44 is connected to a branch pipe 52 via a flexible hose. The hood body 41 is divided into multiple independent dust collection chambers 43 by multiple partitions 42 to achieve precise adaptation to plates of different widths. Each dust collection chamber 43 corresponds to an independent negative pressure channel. By activating only the dust collection chamber 43 corresponding to the plate, the dust collection chambers in the uncovered areas remain closed, avoiding the negative pressure dispersion and energy waste caused by the traditional equipment being open all areas.

[0027] like Figure 5 and Figure 6 As shown, the control component 53 includes a sealing plate 531, a rotating shaft 532, a drive cylinder 533, and a rotating clamp 534. The sealing plate 531 is disposed inside the branch pipe 52. The rotating shaft 532, which is rotatably connected to the branch pipe 52, is connected to the sealing plate 531. One end of the rotating shaft 532 is connected to the rotating clamp 534. The rotating clamp 534 is connected to the drive cylinder 533 through a spherical bearing 535. The drive cylinder 533 is installed on the outer wall of the branch pipe 52. The drive cylinder 533 quickly starts the action, and the linear motion is converted into the rotational motion of the rotating clamp 534 through the spherical bearing 535. The rotating clamp 534 is rigidly fixed to the rotating shaft 532, which can synchronously drive the rotating shaft 532 to rotate, thereby driving the sealing plate 531 inside the branch pipe 52 to flip, realizing the rapid opening and closing of the pipe.

[0028] like Figure 4 and Figure 7 As shown, an air blowing pipe 6 is provided inside the cover 41, and multiple air blowing holes 61 are opened on the air blowing pipe 6; an air pump is connected to the air blowing pipe 6, and air can be blown toward the plate surface through the air holes 61, so that the dust and debris on the plate surface and the grooves and holes are raised and can be easily sucked away by the cover 41.

[0029] Specifically, the blowing direction of the air pipe 6 is set at an angle of 15°-75° with the surface of the plate; preferably, the blowing direction of the air pipe 6 is set at an angle of 25° with the surface of the plate. The blowing direction at a 25° angle can form a composite airflow of oblique impact and upward lifting: on the one hand, the airflow impacts the surface of the plate at an oblique angle, which can effectively break through the adhesion between the dust and the plate surface and completely remove the deep residual dust; on the other hand, the oblique airflow will naturally diffuse upward after impact, forming an upward airflow traction, which accurately guides the peeled dust to the dust suction chamber 43 above, avoiding the dust from spreading to both sides.

[0030] like Figure 4 and Figure 7 As shown, a pressure roller seat 7 is provided inside the cover 41, and a pressure roller 9 is provided at the bottom of the pressure roller seat 7. A pressure roller 8 is provided on one side of the pressure roller 9. The pressure roller 8 and pressure roller 9 below the cover 41 can press on the board surface. When the cover 41 is in contact with the board surface, it plays a role in limiting and reducing friction, thereby reducing the risk of scratching and wear on the board surface by the bottom of the cover 41.

[0031] Specifically, the support frame 1 is fixedly installed on the roller feed table 2 by the support legs 10 and connecting angle iron 11 at its bottom. An air passage plate 12 is provided on one side of the support frame 1. The dust collection device is electrically connected to the electrical control box on the roller feed table 2.

[0032] Working principle: Before the equipment starts operating, the operator rotates the handwheel 314 via the lifting assembly 31, and adjusts the initial height of the dust collection hood component 4 through the transmission structure such as the adjusting screw 312 and adjusting nut 313, so that it is adapted to the thickness of the current batch of plates and leaves room for adjustment. When the upstream plate is transported to the bottom of the equipment, the photoelectric switch detects that the plate has reached the designated position. The central control system synchronously instructs the three-axis cylinder 32 to drive the dust collection hood to descend, the control assembly 53 to open the corresponding branch pipe, and the air blowing pipe 6 to start blowing air. The three-axis cylinder 32 drives the dust collection hood to descend smoothly along the guide structure, so that the pressure roller 8 and the pressure wheel 9 press against each other. The distance between the dust collection hood and the board surface is controlled within the optimal range. Then, the air blowing pipe 6 sprays air at an angle towards the board entry direction to stir up the dust. The negative pressure dust collection mechanism 5 forms negative pressure through the opened branch pipes and sucks the dust into the main dust collection cylinder 51 to achieve dust removal by blowing and suction. During the process, the equipment can close the branch pipes and air blowing in the boardless area according to the board width information of the front-end processing document, and adjust the air blowing pressure according to the transmission speed. After the board is removed, the three-axis cylinder 32 drives the dust collection hood to reset, the air blowing pipe and branch pipes are closed, the pressure sensor detects the status of the air blowing pipe, and the equipment returns to standby, completing the entire dust removal closed loop.

[0033] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
