Description

Technical Field

[0001] The present invention relates to the technical field of fiberboard surface treatment, and particularly relates to a fiberboard surface shaping and processing device. Background Art

[0002] Fiberboard, also known as density board, is a man-made board made from wood fibers or other vegetable fiber raw materials, with urea-formaldehyde resin or other suitable adhesives applied. Adhesives and / or additives can be applied during the manufacturing process. Fiberboard has the advantages of uniform material quality, small difference in longitudinal and transverse strength, and not being prone to cracking, and is widely used. Manufacturing 1 cubic meter of fiberboard requires approximately 2.5 to 3 cubic meters of wood, which can replace 3 cubic meters of sawn timber or 5 cubic meters of logs. Developing fiberboard production is an effective way to comprehensively utilize wood resources. During the production process of fiberboard, its surface needs to be polished. The existing polishing methods usually use sandpaper for polishing, but there are often some problems in the polishing process:

[0003] In common polishing, the sandpaper is usually attached to the moving module, and the surface of the fiberboard is polished by moving. As the number of movements increases, the contact times between the abrasive particles of the sandpaper attached to the moving module and the surface of the fiberboard increase, resulting in a relatively high wear rate of the abrasive particles. The sandpaper needs to be frequently replaced, increasing the labor intensity of the personnel. Summary of the Invention

[0004] (I) Technical Solution

[0005] To solve the above problems, the present invention adopts the following technical solution: A fiberboard surface shaping and processing device includes a placement base, an electric slider, an adjustment mechanism, a moving frame, a polishing mechanism, and a cleaning mechanism. Electric sliders are installed at the front and rear ends of the placement base. An adjustment mechanism is provided on the electric slider. A moving frame is connected between the adjustment mechanisms. A polishing mechanism is provided at the lower end of the moving frame. Cleaning mechanisms are symmetrically provided inside the moving frame, and the cleaning mechanisms are located above the polishing mechanism.

[0006] The polishing mechanism includes a connecting roller. The left and right sides at the lower end of the moving frame are connected to the connecting roller through bearings. The number of connecting rollers is two. An intermittent rotation unit is installed at the front end of the connecting roller on the right side. The connecting rollers are connected by a belt. The outer surface of the belt is attached with sandpaper, which can be replaced when the sandpaper layer of the sandpaper is difficult to perform effective fine polishing. A resisting plate located inside the belt is installed in the moving frame, and the lower end surface of the resisting plate is attached to the surface of the lower part of the belt. A positioning unit for clamping and positioning with the belt is provided on the resisting plate. The setting of the positioning unit temporarily locks and embeds the position of the belt, avoiding the situation that the sandpaper moves along with the surface of the board during polishing.

[0007] The described positioning unit includes a fixed frame. Inside the fixed frame mounted on the abutting plate, a positioning block is slidably arranged up and down. An internal spring is connected between the fixed frame and the positioning block, and the internal spring always maintains a downward pushing trend on the positioning block. Positioning grooves are evenly formed on the belt, and the lower end of the positioning block is located in the positioning groove. The belt is connected in an embedded and locked manner by the elastically connected positioning block.

[0008] The described cleaning mechanism includes an embedded frame. The embedded frame is embedded in the moving frame. A feed port is formed at the lower end of the embedded frame. An air pump is connected and installed between the storage cavity formed in the embedded frame and the feed port. A cleaning unit arranged on the left side of the feed port is installed at the lower end of the embedded frame. The lower half of the embedded frame is located inside the anti-overflow cover, and the anti-overflow cover is installed at the upper end inside the moving frame. The setting of the anti-overflow cover reduces the possibility of air-sucked abrasive particles flying to the outside.

[0009] Among them, the described adjusting mechanism includes a moving slide. The moving slide is arranged on the electric slider. A lifting cylinder is installed between the moving slide and the side wall of the moving frame. The moving frame is driven to lift by the lifting cylinder. An adjustable-height sliding block is arranged at the lower end of the moving frame. The lower end of the sliding block is slidably arranged on the placing base. The sliding of the sliding block in cooperation with the moving frame and the lifting play an auxiliary adjusting role.

[0010] Among them, the described intermittent rotation unit includes a rotating disk. The rotating disk provided with meshing grooves meshes with a rotating rod. The rotating rod is installed on the output shaft of the motor. The motor is installed on the side wall of the moving frame through a motor base.

[0011] Among them, the lower inclined surface of the described positioning block is a structure that gradually slopes upward from left to right. The design of this inclined structure ensures that the connecting roller can drive the belt to rotate clockwise unidirectionally (it cannot rotate counterclockwise). When the sandpaper layer contacts and polishes the upper surface of the plate body, under the insertion of the positioning block, the sandpaper layer will not rotate counterclockwise following the plate body, avoiding the situation where the sandpaper layer is forced to move under the contact of the upper surface of the plate body when the rotating rod separates from the meshing groove.

[0012] Among them, a liftable sealing cover is arranged at the upper end of the storage cavity. By opening the sealing cover, the inhaled abrasive particles can be centrally taken out. The lower end of the feed port does not contact the upper half of the sandpaper layer of the sandpaper, avoiding affecting the adhesion amount of the abrasive on the sandpaper.

[0013] Among them, the described cleaning unit includes a connecting plate. The connecting plate is installed at the lower end of the embedded frame. A flexible cleaning belt that naturally hangs down is installed at the lower end of the connecting plate. The setting of the flexible cleaning belt scrapes and separates some abrasive particles that are about to be separated in a flexible blocking manner, while the abrasive particles with stronger adhesion that can still continue to polish maintain their original connection relationship.

[0014] Among them, the flexible cleaning belt is made of rubber material, which improves the flexibility degree. The left and right arranged flexible cleaning belts are cross-arranged, and a ventilation aisle is left between the cross-arrangements. When the air pump sucks air, the separated abrasive particles can pass through the channel and be sucked in.

[0015] (II) Beneficial effects

[0016] 1. For the fiberboard surface shaping and processing device described in the present invention, the sandpaper is attached to the intermittently rotatable belt, and the part of the sandpaper in contact with the surface of the board body is changed intermittently, so that the elliptically arranged sandpaper can be evenly utilized. Since the length of the attached sandpaper in the present invention is much longer than the length of the sandpaper fixedly attached in the prior art, the replacement frequency is greatly reduced, and the labor intensity of the personnel is reduced;

[0017] 2. For the fiberboard surface shaping and processing device described in the present invention, the area of the elliptically arranged sandpaper in contact with the surface of the board body is relatively large. By expanding the area, the wear degree of a single abrasive particle is reduced, the overall service life of the sandpaper layer is improved, and the replacement frequency is reduced;

[0018] 3. For the fiberboard surface shaping and processing device described in the present invention, the cleaning mechanism is used to flexibly scrape and suck the abrasive particles about to be separated, so that they are completely separated from and sucked away from the paper layer, avoiding the possibility that these abrasive particles increase the appearance of scratches while not playing a polishing role when contacting the surface of the board body subsequently.

[0025] The embodiments of the present invention will be described below with reference to the drawings. During this process, to ensure the clarity and convenience of the description, we may exaggerate the width of the lines or the size of the components in the drawings.

[0026] In addition, the terms used hereinafter are defined based on the functions in the present invention and may vary according to the intentions or conventions of users and operators. Therefore, these terms are defined based on the entire content of this specification.

[0027] As Figures 1 to 5 shown, a fiberboard surface shaping and processing device includes a placement base 1, an electric slider 2, an adjustment mechanism 3, a moving frame 4, a polishing mechanism 5, and a cleaning mechanism 6. Electric sliders 2 are installed at the front and rear ends of the placement base 1. An adjustment mechanism 3 is provided on the electric slider 2. A moving frame 4 is connected between the adjustment mechanisms 3. A polishing mechanism 5 is provided at the lower end of the moving frame 4. Cleaning mechanisms 6 are symmetrically arranged inside the moving frame 4, and the cleaning mechanisms 6 are located above the polishing mechanism 5.

[0028] The adjustment mechanism 3 includes a moving slide base 31. The moving slide base 31 is arranged on the electric slider 2. A lifting cylinder 32 is installed between the moving slide base 31 and the side wall of the moving frame 4. The moving frame 4 is driven to lift by the lifting cylinder 32. An adjustable-height sliding block 33 is provided at the lower end of the moving frame 4. The lower end of the sliding block 33 is slidably arranged on the placement base 1. The sliding block 33 cooperates with the sliding and lifting of the moving frame 4 to play an auxiliary adjustment role.

[0029] The polishing mechanism 5 includes a connecting roller 51. The left and right sides of the lower end of the moving frame 4 are connected to the connecting roller 51 through bearings. The number of connecting rollers 51 is two. An intermittent rotation unit 52 is installed at the front end of the connecting roller 51 on the right side. The connecting rollers 51 are connected by a belt 53. A sandpaper 54 is attached to the outer surface of the belt 53. When the sandpaper layer of the sandpaper 54 is difficult to perform effective fine polishing, it can be replaced. A resisting plate 55 inside the belt 53 is installed in the moving frame 4, and the lower end surface of the resisting plate 55 is attached to the surface of the lower part of the belt 53. A positioning unit 56 for clamping and positioning with the belt 53 is provided on the resisting plate 55. The setting of the positioning unit 56 temporarily locks the position of the belt 53, avoiding the situation that the sandpaper 54 moves along with the board surface during polishing on the board surface.

[0030] During specific work using the above technical solution, during the polishing process, the sandpaper 54 of the polishing mechanism 5 driven by the electric slider 2 moves leftward while descending, so as to perform fine polishing on the upper surface of the fiberboard. After moving leftward for a certain distance, it stops moving. The entire polishing mechanism 5 rises. At this time, the connecting roller 51 is driven to rotate clockwise by the intermittent rotation unit 52, so that the belt 53 drives the sandpaper 54 to rotate a small distance, causing the position of the sandpaper layer in the lower half of the sandpaper 54 to change, thereby ensuring the uniformity of polishing of the sandpaper layer in each area. After the sandpaper 54 rotates a certain distance, it stops rotating. At this time, the polishing mechanism 5 descends, and then continues to move leftward for polishing.

[0031] The intermittent rotation unit 52 described above includes a rotating disk 521. The rotating disk 521 provided with meshing grooves meshes with a rotating rod 522. The rotating rod 522 is installed on the output shaft of a motor 523. The motor 523 is installed on the side wall of the moving frame 4 through a motor base.

[0032] In specific work using the above technical solution, the motor 523 drives the rotating rod 522 to rotate. Under the intermittent meshing of the rotating rod 522 and the meshing grooves, the rotating disk 521 is driven to rotate intermittently, thereby driving the connecting roller 51 to rotate intermittently. When the connecting roller 51 rotates, the polishing mechanism 5 is not in contact with the upper surface of the plate body. When the connecting roller 51 stops rotating, the polishing mechanism 5 is in contact with the upper surface of the plate body.

[0033] The positioning unit 56 described above includes a fixed frame 561. A positioning block 562 is arranged to slide up and down inside the fixed frame 561 installed on the abutting plate 55. An internal spring 563 is connected between the fixed frame 561 and the positioning block 562. The internal spring 563 always maintains a downward pushing trend on the positioning block 562. Positioning grooves are evenly opened on the belt 53, and the lower end of the positioning block 562 is located in the positioning groove. The belt 53 is connected in an embedded and locked manner through the elastically connected positioning block 562. The lower inclined surface of the positioning block 562 is a structure that gradually slopes upward from left to right. The design of this inclined structure ensures that the connecting roller 51 can drive the belt 53 to rotate clockwise in one direction (it cannot rotate counterclockwise). When the sandpaper layer contacts and polishes the upper surface of the plate body, under the insertion of the positioning block 562, the sandpaper layer will not rotate counterclockwise following the plate body, avoiding the situation where the sandpaper layer is forced to move under the contact of the upper surface of the plate body when the rotating rod 522 separates from the meshing groove.

[0034] The cleaning mechanism 6 described above includes an embedded frame 61. The embedded frame 61 is embedded in the moving frame 4. A feed port 62 is opened at the lower end of the embedded frame 61. An air pump 63 is installed in communication between the storage cavity opened in the embedded frame 61 and the feed port 62. A cleaning unit 64 arranged on the left side of the feed port 62 is installed at the lower end of the embedded frame 61. The lower half of the embedded frame 61 is located inside an anti-overflow cover 65, and the anti-overflow cover 65 is installed at the upper end inside the moving frame 4. The setting of the anti-overflow cover 65 reduces the possibility of air-sucked abrasive particles flying to the outside. A liftable sealing cover is arranged at the upper end of the storage cavity. By opening the sealing cover, the inhaled abrasive particles can be centrally taken out. The lower end of the feed port 62 is not in contact with the sandpaper layer of the upper half of the sandpaper 54, avoiding affecting the adhesion amount of the abrasive on the sandpaper 54.

[0035] The described cleaning unit 64 includes a connecting plate 641. The connecting plate 641 is installed at the lower end of the embedded frame 61. At the lower end of the connecting plate 641, a flexible cleaning belt 642 that naturally hangs down is installed. The flexible cleaning belt 642 is arranged to scrape and separate some abrasive particles that are about to be separated in a flexible blocking manner, while the abrasive particles with stronger adhesion that can still continue to polish maintain their original connection relationship. The flexible cleaning belt 642 is made of rubber material, which improves the flexibility degree. Moreover, the left and right arranged flexible cleaning belts 642 are cross-arranged, and a ventilation aisle is left in the cross-arrangement. When the air pump 63 sucks air, the separated abrasive particles can pass through the channel and be sucked in.

[0036] In specific work using the above technical solution, the flexible cleaning belt 642 in the cleaning unit 64 is used to clean the abrasive particles falling off the sandpaper layer in a flexible blocking manner, so that the abrasive particles that have not fallen off are completely separated from the paper layer. Then, the air pump 63 is used to suck the abrasive particles into the storage cavity for temporary storage.

[0037] The implementation principle of this embodiment is as follows:

[0038] S1. Place the fiberboard on the placement base 1;

[0039] S2. Drive the descending polishing mechanism 5 to move leftward through the electric slider 2, and perform fine polishing on the upper surface of the fiberboard through the sandpaper 54. After moving leftward for a certain distance, stop moving. At this time, the polishing mechanism 5 rises as a whole and resets. At this time, drive the connecting roller 51 to rotate clockwise through the intermittent rotation unit 52, and the sandpaper 54 follows the belt 53 to rotate a small distance. The lower layer part of the sandpaper 54 changes. After the rotation stops, the polishing mechanism 5 descends so that the sandpaper layer contacts the fiberboard again. The electric slider 2 continues to drive the polishing mechanism 5 to move leftward, repeating step S2. During the process of polishing the upper surface of the fiberboard, intermittently rotate the position of the sandpaper, so as to continuously maintain the polishing accuracy. For the abrasive particles on the sandpaper layer, the flexible cleaning belt 642 is used to clean the abrasive particles falling off the passing sandpaper layer in a flexible blocking manner, so that the abrasive particles that have not fallen off are completely separated from the paper layer. Then, the fallen abrasive particles are sucked into the storage cavity for temporary storage by air suction;

[0040] S3. After the upper surface of the fiberboard is polished, turn over the fiberboard so that the original lower surface is turned upwards and arranged facing upwards, and perform polishing treatment on the existing upper surface through step S2.

[0041] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
