Description

Technical Field

[0001] This invention belongs to the technical field of automatic edge banding machines, specifically an edge scraping device for an automatic edge banding machine. Background Technology

[0002] An automatic edge banding machine is a high-efficiency, automated woodworking machinery. Its function is to apply glue to the edges of boards for edge banding. To ensure the quality of edge banding, the width of the edge banding strip is generally greater than the width of the board. After the edge banding is completed, there will be excess edge banding and residual glue, at which point the board needs to be scraped.

[0003] The new edge-scraping assembly consists of a fixed pair of scrapers. After scraping the board, residue and adhesive residue may accumulate at the blade head. Long-term accumulation will affect the quality of the edge scraping. Cleaning this requires disassembling the blade assembly, which is very troublesome. In addition, cleaning the residue that splashes and accumulates during edge scraping is also very tedious. At the same time, after the blade assembly is fixed, when the board moves between the blade heads, the blade may jump. After the blade assembly is fixed, the fixed blade needs to be removed and the position readjusted after changing the board, which is also very tedious. Therefore, an edge scraping device for an automatic edge banding machine is proposed. Summary of the Invention

[0004] To address the problems mentioned in the background art, such as the accumulation of residue and adhesive at the cutter head, the difficulty in cleaning up the splashed residue, the potential for cutter skipping, and the cumbersome process of fixing and adjusting the cutter assembly, this invention provides an edge-scraping device for an automatic edge-sealing machine.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an edge-scraping device for an automatic edge-sealing machine, comprising a main support, a first sliding seat and a second sliding seat disposed in the middle of the main support, positioning components movably connected to the sides of both the first and second sliding seats, a second cylinder fixedly connected to the top of the main support, a transverse positioning wheel fixedly connected to the top of the second sliding seat, a plate movably connected in the middle of the positioning components, a support and blocking component fixedly connected to the side of the first and second sliding seats away from the positioning components, an edge-scraping component slidably connected inside the support and blocking component, and a bonding plate fixedly connected between the edge-scraping components;

[0006] The support and blocking assembly includes a first baffle and a second baffle. The top of the second baffle and the bottom of the support plate are both fixedly connected to the support plate, and a residue pipe is opened at the bottom of the second baffle.

[0007] The scraping assembly includes a pair of support housings, a pair of slide rails at the front end of the support housings, a drive mechanism fixedly connected to the middle of the support housings, a pair of scraper rods rotatably connected inside the support housings, and limit toothed plates slidably connected on the slide rails.

[0008] Preferably, the first sliding seat is located above the second sliding seat, the first sliding seat is slidably connected to the main support, the second sliding seat is fixedly connected to the main support, the output end of the second cylinder passes through the top of the main support and is fixedly connected to the first sliding seat, and the transverse positioning wheel abuts against the plate.

[0009] Preferably, the positioning component includes a pair of fixed frames, a slide rod is fixedly connected inside the fixed frames, a vertical positioning wheel is provided at the front end of the fixed frames, and a first cylinder is fixedly connected to the rear end of the slide rod.

[0010] Preferably, the fixing frame is C-shaped, and the fixing frame is engaged with the first sliding seat and the second sliding seat respectively. The sliding rod is slidably connected with the first sliding seat and the second sliding seat respectively. The vertical positioning wheel abuts against the plate. The first cylinder passes through the rear end of the sliding rod and is fixedly connected with the first sliding seat and the second sliding seat respectively.

[0011] Preferably, the support and blocking assembly further includes a cleaning wheel, which is rotatably connected to the middle of the first baffle and the second baffle, and a motor is fixedly connected to one end of the cleaning wheel.

[0012] Preferably, the first baffle is fixedly connected to the first sliding seat, the second baffle is fixedly connected to the second sliding seat, the second baffle surrounds the periphery of the first baffle, the residue tube is externally connected to a dust collection mechanism, and the motor is located outside the first baffle and the second baffle, and is fixedly connected to the first baffle and the second baffle.

[0013] Preferably, the scraping assembly further includes a limiting groove, which is formed inside the support housing. A sliding rod is slidably connected inside the limiting groove. Scraping blades are fixedly installed at the bottom of each pair of scraper rods. A spring is fixedly connected to the top of the support housing.

[0014] Preferably, the support housing is slidably connected to the support plate, the middle part of the sliding rod is rotatably connected to the scraper rod, the outer end of the sliding rod is rotatably connected to the limiting tooth plate, the driving mechanism is located between a pair of limiting tooth plates and is engaged with the limiting tooth plate, and one end of the spring is fixedly connected to the support plate.

[0015] Preferably, when the drive mechanism drives the slide rails to move, the pair of slide rails move in opposite directions, causing the pair of scraper bars to rotate in opposite directions, so that one scraper blade moves into the interior of the mounting plate, while the other scraper blade rotates to a horizontal position.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] This invention solves the problem of residue and adhesive accumulating at the blade head and the difficulty in cleaning up splashed residue by setting up a scraping component and a support and blocking component. The drive mechanism drives a pair of limiting tooth plates to move in opposite directions, so that the scraping blade moves alternately with the scraping bar via the sliding rod. This causes the pair of scraping blades to switch positions, so that one scraping blade moves into the inside of the board to scrape the edge of the board, while the other scraping blade comes into contact with the cleaning wheel and is cleaned by the blade head of the scraping blade on the cleaning wheel, avoiding the accumulation of residue and adhesive residue. The scraping blades scrape the board alternately, keeping the scraping blades clean at all times. The debris generated during scraping is blocked inside by the baffle and then sucked out by the dust suction device connected to the residue tube.

[0019] This invention solves the problem of tool skipping by setting up a scraping component and a support blocking component. By sliding the support housing and the support plate together and setting the spring between the support plate and the support housing, the support housing remains stable under the buffer of the spring when the board passes over the bonding plate, so that the bonding plate and the board fit together and the tool skipping is avoided.

[0020] This invention solves the problem of cumbersome knife assembly fixing and adjustment by setting up a scraping component and a sliding seat. According to the thickness of the plate, the second cylinder is activated to adjust the vertical position of the first sliding seat, so as to drive the support housing to move up and down, thereby adjusting the distance between the scraping knives.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figures 1 to 8 As shown, the present invention provides an edge scraping device for an automatic edge banding machine, including a main support 1, a first sliding seat 2 and a second sliding seat 3 arranged in the middle of the main support 1, positioning components 4 movably connected to the sides of the first sliding seat 2 and the second sliding seat 3, a second cylinder 5 fixedly connected to the top of the main support 1, a transverse positioning wheel 6 fixedly connected to the top of the second sliding seat 3, a plate 7 movably connected in the middle of the positioning components 4, a support blocking component 8 fixedly connected to the side of the first sliding seat 2 and the second sliding seat 3 away from the positioning components 4, an edge scraping component 9 slidably connected inside the support blocking component 8, and a bonding plate 10 fixedly connected between the edge scraping components 9;

[0032] Among them, the support and blocking assembly 8 includes a first baffle 81 and a second baffle 82. The top of the second baffle 82 and the bottom of the support plate 83 are both fixedly connected to the support plate 83. A residue pipe 84 is opened at the bottom of the second baffle 82.

[0033] The scraping assembly 9 includes a pair of support housings 91, a pair of slide rails 93 at the front end of the support housings 91, a drive mechanism 94 fixedly connected to the middle of the support housings 91, a pair of scraper rods 96 rotatably connected inside the support housings 91, and limit toothed plates 99 slidably connected on each of the slide rails 93.

[0034] The above scheme is adopted as follows: by activating the second cylinder 5 to adjust the vertical position of the first sliding seat 2, and by activating the first cylinder 44 to push the slide rod 42 to move, the extension length of the vertical positioning wheel 43 is adjusted. After the plate 7 is conveyed to the positioning assembly 4 by the conveyor belt, the vertical positioning wheel 43 and the horizontal positioning wheel 6 cooperate to position and clamp the plate 7, keeping the plate 7 stable. Then the plate 7 enters the bonding plate 10, and the plate 7 pushes the bonding plate 10 to move to the upper and lower ends. Then, under the buffer of the spring 98, the bonding plate 10 is attached to the surface of the plate 7. Then the edge scraper 97 scrapes the edge of the plate 7. The debris generated by scraping splashes into the first baffle 81 and the second baffle 82, and is then sucked out by the dust suction device connected to the residue pipe 84. After scraping the edge of a plate, the drive mechanism 94 is activated, so that the edge scraper 97 drives the scraper rod 96 to move alternately through the sliding rod 95, so that the edge scraper 97 scrapes the edge of the plate 7 alternately, keeping the edge scraper 97 clean at all times.

[0035] like Figure 2 and Figure 3 As shown, the first sliding seat 2 is located above the second sliding seat 3. The first sliding seat 2 is slidably connected to the main support 1, and the second sliding seat 3 is fixedly connected to the main support 1. The output end of the second cylinder 5 passes through the top of the main support 1 and is fixedly connected to the first sliding seat 2. The transverse positioning wheel 6 abuts against the plate 7.

[0036] The above solution is adopted as follows: by installing a first sliding seat 2 and a second sliding seat 3 in the middle of the main support 1, the first sliding seat 2 is set to be slidably connected to the main support 1, so that the first sliding seat 2 can slide to adjust the distance between it and the second sliding seat 3. The output end of the second cylinder 5 passes through the top of the main support 1 and is fixedly connected to the first sliding seat 2, so as to control the distance of movement of the first sliding seat 2. By setting the transverse positioning wheel 6 to abut against the plate 7, the transverse position of the plate 7 can be positioned.

[0037] like Figure 2 , Figure 3 and Figure 4 As shown, the positioning component 4 includes a pair of fixed frames 41. A slide rod 42 is fixedly connected inside the fixed frame 41. A vertical positioning wheel 43 is provided at the front end of the fixed frame 41. A first cylinder 44 is fixedly connected to the rear end of the slide rod 42. The fixed frame 41 is C-shaped. The fixed frame 41 is engaged with the first sliding seat 2 and the second sliding seat 3 respectively. The slide rod 42 is slidably connected with the first sliding seat 2 and the second sliding seat 3 respectively. The vertical positioning wheel 43 abuts against the plate 7. The first cylinder 44 passes through the rear end of the slide rod 42 and is fixedly connected to the first sliding seat 2 and the second sliding seat 3 respectively.

[0038] The above solution is adopted as follows: by setting a positioning component 4, a sliding rod 42 is fixedly connected inside the fixed frame 41, and the fixed frame 41 is respectively engaged with the sides of the first sliding seat 2 and the second sliding seat 3, so that the fixed frame 41 can move with the first sliding seat 2, move up and down synchronously and remain stable, and the fixed frame 41 drives the vertical positioning wheel 43 to move vertically, so as to adjust the distance between the two vertical positioning wheels 43 to correspond to plates of different thicknesses. At the same time, the sliding rod 42 is slidably connected with the first sliding seat 2 and the second sliding seat 3 respectively. Through the first cylinder 44 set at the rear end of the sliding rod 42, the fixed frame 41 and the sliding rod 42 can be pushed to slide on the sides of the first sliding seat 2 and the second sliding seat 3 respectively, so as to adjust the extension length of the vertical positioning wheel 43.

[0039] like Figure 4 , Figure 5 and Figure 6 As shown, the support and blocking assembly 8 also includes a cleaning wheel 85, which is rotatably connected to the middle of the first baffle 81 and the second baffle 82 respectively. A motor 86 is fixedly connected to one end of the cleaning wheel 85. The first baffle 81 is fixedly connected to the first sliding seat 2, and the second baffle 82 is fixedly connected to the second sliding seat 3. The second baffle 82 surrounds the periphery of the first baffle 81. A dust suction mechanism is connected to the outside of the residue tube 84. The motor 86 is located outside the first baffle 81 and the second baffle 82 and is fixedly connected to the first baffle 81 and the second baffle 82.

[0040] The above scheme is adopted as follows: the support blocking assembly 8 is set as a first baffle 81 and a second baffle 82. Support plates 83 are set at the top of the second baffle 82 and the bottom of the support plate 83 to support the support housing 91 and are fixedly connected to the spring 98, so that the support housing 91 has room to move. A residue pipe 84 is opened at the bottom of the second baffle 82, and a dust collection mechanism is connected to the outside of the residue pipe 84 to collect the debris generated by the scraping knife 97 when scraping the edge of the plate 7. The second baffle 82 is set to surround the first baffle 81, so that the second baffle 82 and the first baffle 81 cooperate to prevent the debris generated by scraping from splashing into the equipment and accumulating. A cleaning wheel 85 is set in the middle of the first baffle 81 and the second baffle 82 to clean the scraping knife 97 and prevent residue from entanglement and solidification of residual glue.

[0041] like Figures 5 to 8 As shown, the scraping assembly 9 also includes a limiting slide groove 92, which is opened inside the support housing 91. A sliding rod 95 is slidably connected inside the limiting slide groove 92. A scraping blade 97 is fixedly installed at the bottom of a pair of scraping rods 96. A spring 98 is fixedly connected to the top of the support housing 91.

[0042] The above solution is adopted as follows: by setting the scraping component 9, a limiting groove 92 is opened inside the support housing 91 for the sliding of the sliding rod 95. A pair of slide rails 93 are set at the front end of the support housing 91 for limiting the limiting tooth plate 99. The driving mechanism 94 is set in the middle of the support housing 91, and the limiting tooth plate 99 can be driven to slide by the driving mechanism 94. The sliding rod 95 is movably connected to the scraper rod 96 and the limiting tooth plate 99 respectively, so that the limiting tooth plate 99 can drive the scraper rod 96 to rotate through the sliding rod 95. The design of a pair of scraper rods 96 allows the scraper rods 96 to enter the interior of the board plate 10 in an alternating manner to scrape the edge of the board 7.

[0043] like Figures 5 to 8 As shown, the support housing 91 is slidably connected to the support plate 83, the middle part of the sliding rod 95 is rotatably connected to the scraper rod 96, and the outer end of the sliding rod 95 is rotatably connected to the limiting tooth plate 99. The drive mechanism 94 is located between the pair of limiting tooth plates 99 and is engaged with the limiting tooth plate 99. One end of the spring 98 is fixedly connected to the support plate 83. When the drive mechanism 94 drives the slide rail 93 to move, the pair of slide rails 93 move in opposite directions, causing the pair of scraper rods 96 to rotate in opposite directions, so that a scraper blade 97 moves into the inside of the pasting plate 10.

[0044] The above solution involves sliding the support housing 91 to the support plate 83 and placing the spring 98 between the support plate 83 and the support housing 91. When the board passes over the bonding plate 10, the support housing 91 remains stable under the buffering effect of the spring 98, ensuring that the bonding plate 10 adheres to the board and preventing blade skipping. The drive mechanism 94 is positioned between a pair of limiting toothed plates 99 and meshes with them, allowing the drive mechanism 94 to drive the pair of limiting toothed plates 99 to move in opposite directions. This causes the scraping blade 97 to move alternately via the sliding rod 95, switching the positions of the pair of scraping blades 97. One scraping blade 97 moves into the interior of the bonding plate 10 to scrape the edge of the board 7, while the other scraping blade 97 contacts the cleaning wheel 85 and is cleaned by the blade head of the scraping blade 97 on the cleaning wheel 85, preventing residue accumulation and adhesive residue.

[0045] like Figure 8 As shown, when the scraper bar 96 is rotated to a horizontal position, the blade head of the scraper blade 97 will come into contact with the cleaning wheel 85, and the bottom ends of the adhesive plate 10 will be tilted upwards.

[0046] The above solution is adopted: by rotating the scraper bar 96 to a horizontal state, the scraper blade 97 will come into contact with the cleaning wheel 85 for cleaning. The bottom ends of the bonding plate 10 are set to be inclined upwards, so that when the board enters the middle of the bonding plate 10, it can be gradually pushed open by the board and keep in contact with the board, avoiding the blade jumping.

[0047] The working principle and usage process of this invention are as follows: During operation, firstly, based on the thickness of the sheet material, the second cylinder 5 is activated to adjust the vertical position of the first sliding seat 2. Then, the first cylinder 44 is activated to push the slide rod 42 to move, adjusting the extension length of the vertical positioning wheel 43. After the sheet material 7 is conveyed to the positioning assembly 4 via the conveyor belt, the vertical positioning wheel 43 and the horizontal positioning wheel 6 cooperate to position and clamp the sheet material 7, maintaining its stability. Then, the sheet material 7 enters the bonding plate 10, pushing the bonding plate 10 to move upward and downward. Then, under the buffer of the spring 98, the bonding plate 10 adheres to the surface of the sheet material 7. Finally, the edge of the sheet material 7 is scraped by the scraping blade 97. The debris generated during scraping splashes into the... The material enters the first baffle 81 and the second baffle 82, and is sucked out by the dust suction device connected to the residue pipe 84. After scraping the edge of a piece of board, the drive mechanism 94 is activated to drive a pair of limiting tooth plates 99 to move in opposite directions, so that the scraping blade 97 moves alternately through the sliding rod 95 to drive the scraper rod 96, causing the pair of scraping blades 97 to switch positions. One scraping blade 97 moves into the inside of the board plate 10 to scrape the edge of the board 7, while the other scraping blade 97 abuts against the cleaning wheel 85 and is cleaned by the blade head of the scraping blade 97 on the cleaning wheel 85 to avoid the accumulation of residue and residual glue. The scraping blades 97 scrape the edge of the board 7 alternately, so that the scraping blades 97 are always kept clean.
