Description

Technical Field

[0001] The utility model belongs to the technical field of wooden board processing, in particular to a device for deburring the surface of wooden furniture boards. Background Art

[0002] Wooden furniture is a type of furniture made of wood panels as processing materials and processed according to designed furniture drawings.

[0003] In the process of wooden furniture processing, the processed boards are cut and formed to obtain board blanks, and the board blanks are then subjected to subsequent processes such as painting to obtain cost boards. The finished boards are then installed according to the processing drawings to obtain furniture.

[0004] Therefore, the treatment of wood panels is the key to the quality of finished wooden furniture. Specifically, because wood panels, especially logs, have a large number of burrs, only after the burrs are fully removed can the paint adhere smoothly to the panels after subsequent painting, ensuring that the painted surface of the furniture is smooth and burr-free.

[0005] The current method of removing burrs is that the operator manually polishes the board using a polishing machine. The disadvantage of this method is that it not only has low processing efficiency, but also generates a large amount of wood dust during the processing, which seriously endangers the health of the operator.

[0006] At the same time, since the plate has a certain surface area, it is difficult for the operator to operate it. Specifically, the operator can only polish the plate along the four sides with a handheld polishing machine to ensure that the center and near-center parts of the plate can be polished.

[0007] At the same time, in the actual working process, the hand-throwing method is prone to defects such as missed throwing, resulting in low polishing efficiency.

[0008] While mechanical polishing is relatively efficient, traditional polishing machines also have significant drawbacks: When feeding plates of varying sizes into the polishing machine, the plates are prone to shaking under the polishing force, resulting in instability. This requires the coordination of multiple operators, who simultaneously push the plates and support their sides to prevent shaking.

[0009] At the same time, due to the different thicknesses of different plates, the polishing force of thin plates is not enough during the polishing process, resulting in incomplete burr removal. Utility Model Content

[0010] Based on the above background, the purpose of the present invention is to provide a device for deburring the surface of wooden furniture panels.

[0011] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0019] Preferably, a rectangular sliding opening is formed on the convex seat, and the spring sliding structure includes a sliding rod fixedly connected to the rectangular sliding opening; the sliding rod is slidably connected to the sliding roller seat;

[0020] The slide rod is sleeved with a spring, and both ends of the spring are fixedly connected to the rectangular slide and the slide roller seat respectively;

[0021] The top and the bottom of the friction roller are rotatably connected to a rotating shaft respectively, and the rotating shaft is fixedly connected to the sliding roller seat.

[0022] Preferably, a plurality of adjusting claws are fixedly connected to the front and rear sides of the deburring roller adjustment seat respectively;

[0023] The top of the frame is fixedly connected with a fixed convex seat, and the fixed convex seat is fixedly connected with a plurality of adjusting screws slidably connected with the adjusting claws. The adjusting screws are threadedly connected with a pair of nuts positioned on both sides of the adjusting claws.

[0024] Preferably, the deburring roller adjustment seat is provided with a mounting hole corresponding to the deburring roller;

[0025] End seats are fixedly connected to both sides of the mounting hole, and rotating shafts are fixedly connected to both ends of the deburring roller, and the rotating shafts are rotatably connected to the end seats.

[0026] The belt transmission structure includes a pulley motor fixedly mounted on the dehairing roller adjustment seat, and the pulley motor is connected to the rotating shaft through the pulley structure;

[0031] The utility model has the following beneficial effects:

[0032] 1. During operation, when a sheet is loaded onto the conveyor belt, both ends of the sheet contact the contact rollers. The contact rollers, in a rotating connection, roll against the sheet. During this contact, the sliding roller seat compresses the spring and slides inwards towards the cam. This creates elastic contact. Furthermore, sheets of varying sizes can be conveyed in this contact state. This ensures that the sheet's contact facilitates deburring by the deburring assembly described below.

[0033] 2. During the height adjustment process, loosen the nut and adjust the height of the deburring roller adjustment seat to adjust according to the thickness of the plate. If the thickness of the plate is thin, adjust it downward to ensure that the deburring roller can remove the burrs on the plate under high-speed rotation.

[0034] 3. During operation, the deburring roller, driven by a pulley motor, rotates at high speed. (The surface of the deburring roller has been roughened by grinding, and the high-speed rotation of the roller removes the burrs.) Specifically, the operator places the plate on the conveyor belt. As the conveyor belt moves, the plate slowly advances. Because the two sides of the plate are in a state of friction, the plate does not shake during the grinding process. During the grinding process, the operator can manually support the ends of the plate to control the speed of the plate and ensure that the plate is fully polished. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Example 1

[0046] like Figure 1-5 As shown, a surface deburring device for wooden furniture panels includes a deburring mechanism, wherein the deburring mechanism includes a belt conveyor 2, and the belt conveyor 2 is a conventional belt conveyor device disclosed in the prior art, and its main structure includes a belt conveyor 2 including frames spaced apart on the front and rear sides, and a transmission belt is installed between the frames.

[0047] Specifically, the frame includes frame end mounts 11 spaced apart on either side. The belt conveyor 2 also includes belt rollers rotatably connected between the frame end mounts (a driving belt roller 22 on the left and a driven belt roller 24 on the right). A drive motor 21 is mounted on the left belt roller. Specifically, according to conventional methods, a rotating shaft is mounted at each end of the driving belt roller 22 and the driven belt roller 24. The rotating shaft is rotatably connected to bearings mounted on the frame end mounts. The output shaft of the drive motor 21 is mounted to the rotating shaft via a flange connection plate. According to conventional methods, the drive motor 21 is fixedly mounted on a motor support frame (not shown).

[0048] At the same time, a connecting beam 12 is fixedly connected between the frame end seats 11.

[0049] Several roller assemblies 3 that elastically press against the side edges of the plate are fixedly assembled on the connecting beam 12; with the cooperation of the front and rear roller assemblies 3, when the plate is loaded onto the conveyor belt, the side edges of the plate elastically press against the roller assemblies 3 during the transmission process, thereby ensuring that the plate does not shake during the grinding process.

[0050] And after loading plates of different widths, the plates can be loaded and transported under the side friction.

[0051] The roller assembly 3 includes a roller frame 31 fixedly installed at the top position of the connecting beam frame. The roller frame 31 is integrally formed with upper and lower convex seats 32 spaced apart inwardly. The convex seats 32 are slidably connected to the sliding roller seats 331 through a spring sliding structure, and the sliding roller seats 31 are rotatably connected to the contact rollers 33.

[0052] Specifically, a rectangular sliding opening is opened on the convex seat, and the spring sliding structure includes a sliding rod 34 fixedly connected in the rectangular sliding opening; the sliding rod 34 is slidably connected to the sliding roller seat 331;

[0053] The slide rod 34 is sleeved with a spring 341 , and both ends of the spring 341 are fixedly connected to the rectangular slide and the sliding roller seat 331 ; the top and bottom of the resisting roller 33 are rotatably connected to a rotating shaft, which is fixedly connected to the sliding roller seat 331 .

[0054] During operation, when a sheet of material is loaded onto the conveyor belt, its ends contact the contact rollers 33. The contact rollers 33, in their rotating connection, roll against the sheet. During this contact, the sliding roller seat 331 compresses the spring 341 and slides inwards towards the cam. This creates elastic contact, allowing sheets of varying sizes to be conveyed in this state of contact. This ensures that the sheet's contact facilitates burr removal by the deburring assembly described below.

[0055] Example 2

[0056] like Figure 1-5 As shown, based on the structure of Example 1, the deburring mechanism of this embodiment further includes a deburring assembly installed between the tops of the frames, the deburring assembly including a deburring roller adjustment seat 45 with an adjustable height, a deburring roller being rotatably connected to the deburring roller adjustment seat 45; the deburring roller is driven to rotate by a belt transmission structure.

[0057] Specifically, a plurality of adjusting claws 42 are fixedly connected to the front and rear sides of the deburring roller adjustment seat 45; a fixed boss is fixedly connected to the top of the frame, and a plurality of adjusting screws 421 slidingly connected to the adjusting claws 42 are fixedly connected to the fixed boss, and a pair of nuts 4211 positioned on both sides of the adjusting claw 42 are threadedly connected to the adjusting screws 421.

[0058] During the height adjustment process, loosen the nut 4211 and adjust the height of the deburring roller adjustment seat 45 to adjust according to the thickness of the plate. If the thickness of the plate is thin, adjust it downward to ensure that the deburring roller can remove the burrs on the plate under high-speed rotation.

[0059] At the same time, the deburring roller adjustment seat 45 is provided with a mounting hole corresponding to the deburring roller 44; specifically, end seats are fixedly connected on both sides of the mounting hole (according to the existing method, bearings are installed on the end seats, and the rotating shaft is rotatably connected in the bearings), and the two ends of the deburring roller 44 are fixedly connected with a rotating shaft, which is rotatably connected to the end seat.

[0060] The above-mentioned belt transmission structure includes a pulley motor 46 fixedly mounted on the deburring roller 44 adjustment seat 45, and the pulley motor 46 is connected to the rotating shaft through a pulley structure 461; the pulley structure 461 includes a driven pulley mounted on the rotating shaft, and a driving pulley is mounted on the output shaft of the pulley motor 46, and the driven pulley and the driving pulley are connected through a transmission belt.

[0061] During operation, the deburring roller 44, driven by a pulley motor 46, rotates at high speed. (The surface of the deburring roller 44 has been roughened and polished, and the high-speed rotation of the roller scrapes and removes the burrs.) Specifically, the operator places the sheet material on the conveyor belt. As the conveyor belt moves, the sheet material slowly advances. Because the two sides of the sheet material are in a state of friction, the sheet material does not shake during the polishing process. During the polishing process, the operator can manually support the ends of the sheet material to control the speed of the sheet material and ensure that the sheet material is fully polished.

[0062] To enhance grinding stability during the grinding process, supporting rollers corresponding to the deburring rollers 44 are rotatably connected between the frames. The supporting rollers are similarly rotatably connected to bearings mounted on the frames via fixed rotating shafts at both ends. These supporting rollers are located directly below the deburring rollers 44, inside the conveyor belt. The number of supporting rollers can be increased based on actual working conditions to ensure smooth sheet material conveyance during the grinding process.

[0063] Example 3

[0064] like Figure 1-5 As shown, based on the structure of Example 2, in order to prevent a large amount of dust from escaping during the grinding and deburring process, the deburring roller 44 adjustment seat 45 is fixedly connected with a dust cover 5 covering the deburring roller 44; the dust cover 5 is arc-shaped.

[0065] In accordance with existing dust extraction methods, a dust extraction pipe 51 is connected to the top of the dust cover 5. The dust extraction pipe 51 is connected to an external exhaust duct (not shown) through a flexible connecting pipe (not shown). As in existing methods, an exhaust fan (not shown), such as an axial flow fan, is installed in the external exhaust duct to extract dust during the grinding process.

[0066] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
