Description

Technical Field

[0001] This utility model relates to the field of panel furniture processing, and in particular to a rough finishing device for an edge banding machine. Background Technology

[0002] An edge banding machine is a piece of equipment used in furniture manufacturing and woodworking industries. It is mainly used to seal the edges of wood boards, enhancing their appearance and durability. It creates a smooth and neat edge banding effect by attaching edge banding strips to the edges of the wood boards. Edge banding machines are generally divided into manual and automatic types. Automatic edge banding machines are more efficient and suitable for large-scale production. Common edge banding materials include PVC, ABS, and wood veneer. The equipment completes the edge banding process through hot melt adhesive and pressing processes, and is widely used in the production of furniture such as cabinets and wardrobes.

[0003] Rough finishing is an important step in board processing. It is mainly used to remove uneven parts on the board surface, and to trim burrs, defects or irregular edges to ensure the smoothness and flatness of the board. In the edge banding direction, the purpose of rough finishing is to provide a better foundation for the subsequent edge banding process, so that the edge banding strip can be evenly and firmly adhered to the edge of the board. During the rough finishing process, the finishing direction is usually adjusted according to the size and shape of the board to ensure that the edge of each board meets the standard requirements and to avoid unevenness or detachment during edge banding.

[0004] The purpose of rough trimming is to trim the excess edge banding that protrudes beyond the upper and lower surfaces of the wooden board to a suitable protrusion height, preparing for the next fine trimming process. The adjustment force of the upper and lower contour discs should be such that when the pressure roller is pressing the workpiece, it can be moved by hand with a little force. However, if the pressure of a traditional edge banding machine is too high, the front end of the workpiece is easily damaged. If the pressure is too low, it cannot properly contour, resulting in poor trimming effect or even failure to trim the edge. Therefore, a rough trimming device for an edge banding machine is proposed to solve the above problems. Utility Model Content

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] Reference Figure 1 - Figure 19The present invention provides an embodiment of a roughing device for an edge banding machine, comprising a bracket 1, two guide rods 2 fixedly connected to the inner side of the bracket 1, a lower limit block 3 fixedly connected to the bottom of the front guide rod 2, the bracket 1 supporting the entire device, the guide rods 2 limiting the movement direction of the trimming adjustment component, the lower limit block 3 limiting the movement distance of the lower sliding block 4, a trimming adjustment component installed between the two guide rods 2, a buffer component installed on the left side of the trimming adjustment component, and a feed component installed on the rear side of the trimming adjustment component;

[0047] The cutting adjustment assembly includes two sliding blocks 4, which are internally slidably connected between the two guide rods 2. An adjusting screw 37 is fixedly connected to the bottom of the lower sliding block 4, and a nut 38 is threaded onto the outside of the adjusting screw 37. A spring 39 is fitted onto the outside of the adjusting screw 37. A top plate 50 is fixedly connected to the right side of the lower sliding block 4, and an adjusting screw 47 is fixedly connected to the top of the lower sliding block 4. A nut 48 is threaded onto the outside of the adjusting screw 47. A cylinder 2 49 is fixedly connected to the right side of the upper sliding block 4, and a screw 5 is rotatably connected inside the upper sliding block 4. A pressure ring 6 is slidably connected to the outside of the screw 5, and the pressure ring 6 is fixed inside the screw 5 by a pin 7. A spring sleeve 1 9 is fixedly connected to the top of the pressure ring 6. A spring 8 is fitted onto the upper side of a screw 5, a spring 13 is fitted onto the lower side of the screw 5, a sleeve 10 is slidably connected to the upper side of the screw 5, a nut 11 is threaded onto the external side of the screw 5, the bottom of the nut 11 abuts against the top of the sleeve 10, a handle 12 is fixedly connected to the top of the screw 5, a connecting copper block 51 is fixedly connected to the upper side of the screw 5, two guide rods 2 are fixed in the bracket 1, a sliding block 4 is fitted with a sliding seat 16, the sliding block 4 slides up and down along the sliding seat 16, a bearing 14 is fitted on the sliding block 4, two guide rods 2 15 are fixed on the sliding seat 16, the sliding seat 16 slides back and forth along the bearing 14 through the guide rods 2 15, the connecting copper block 51 is inserted into the bracket 1, it rises or falls with the upper beam, the connecting copper block 51 is fixed when the upper beam is stationary. The connecting copper block 51 has a threaded hole, and the screw 5 has a length of external thread. The screw 5 is screwed into the connecting copper block 51 through the thread. The pressure ring 6 is a hollow tube with a long hole at the bottom. The screw 5 is inserted into the inner diameter of the pressure ring 6, pressing the spring 13 at the bottom. The nut 11 is screwed into the screw 5, and its bottom surface presses against the upper end face of the sleeve 10. When the nut 11 is turned and moves downward along the screw 5, the sleeve 10 and the pressure ring 6 also move downward, increasing the compression of the spring 13 and its elastic force. Similarly, when the nut 11 is turned upward, the elastic force of the spring 13 decreases. The central hole of the pressure ring 6 passes through the sleeve 10. The connection between the pressure ring 6 and the screw 5 is achieved by a pin 7 passing through the holes of both. Nail 7 passes through the elongated hole of pressure ring 6. Spring 8 is installed between spring sleeve 9 and pressure ring 6, with its bottom contacting pressure ring 6. Since pressure ring 6 is fixed to screw 5, and screw 5 is connected to connecting copper block 51 by threads, pressure ring 6 will not move as long as screw 5 is not turned. The central hole of spring sleeve 9 passes through pressure ring 6. Under the action of gravity, sliding block 4 and spring sleeve 9 move downward. When spring sleeve 9 begins to contact spring 8, the elastic force of spring 8 reacts to gravity until the two reach a state of equilibrium. At this time, sliding block 4 and spring sleeve 9 will no longer move downward. Adjusting screw 4 37 is installed at the bottom of sliding block 4. Nut 4 38 is screwed into the thread of adjusting screw 4 37. Spring 4 39 passes into adjusting screw 4 37, with its upper end face contacting nut 4 38.Adjusting screw 47 is screwed into the corresponding screw hole of bracket 1. One end of adjusting screw 47 presses against sliding block 4. Turning adjusting screw 47 downwards compresses spring 4 39, causing sliding block 4 to move downwards. Turning adjusting screw 47 upwards causes sliding block 4 to move upwards under the spring force of spring 4 39. Turning nut 4 38 downwards compresses spring 4 39. This is to balance the weight of the adjustment mechanism with the spring force, and to require that the outer diameter of the contour disc 36 is lower than the surface of the wooden board. The bottom of spring 2 13 is fixedly connected to the inside of sliding block 4, and the top of spring 2 13 and the bottom of pressure ring 6 abut against each other. The connection ensures the stability of spring 13. The bottom of sleeve 10 abuts against the top of bracket 1. Screw 5 is externally rotatably connected to the inside of bracket 1, ensuring its stability. Connecting copper block 51 is externally slidably connected to the upper side of bracket 1 for easy installation. The bottom of spring 39 is fixedly connected to the inside of bracket 1, ensuring its stability. The output end of cylinder 49 abuts against the top of top plate 50, causing the two sliding blocks 4 to move in opposite directions. Adjusting screw 47 is externally slidably connected to the inside of bracket 1, limiting its direction of movement.

[0048] Reference Figure 1 - Figure 19The buffer assembly includes two bearings 14, which are externally fixedly connected to the inside of a sliding block 4. A guide rod 15 is slidably connected inside the bearings 14. A slide block 16 is slidably connected between the two guide rods 15. An adjusting block 17 is fixedly connected to the front of the slide block 16, and a mounting block 18 is rotatably connected to the front of the slide block 16. An adjusting screw 21 is installed between the adjusting block 17 and the mounting block 18. An adjusting screw 19 is threadedly connected inside the mounting block 18. A spring 20 is sleeved on the outside of the adjusting screw 19. The adjusting screw 21 is installed between the adjusting block 17 and the mounting block 18. A cylinder 22 is installed between the adjusting block 17 and the mounting block 18. An adjusting screw 23 is fixedly connected to the output end of the cylinder 22. The adjusting screw 23 is externally threaded... The system includes a nut 24 for threaded connection, a screw 25 for fixed connection to the top of the adjusting block 17, a counter 26 for fixed connection to the upper side of the screw 25, a handle 27 for fixed connection to the top of the screw 25, a contour disc 36 for rotatable connection to the front of the mounting block 18, a fixing screw 30 for fixed connection to the left side of the slide block 16, a locking screw 28 for fixed connection to the left side of the slide block 16, a nut 29 for external threaded connection to the locking screw 28, a mounting plate 31 for slidable connection to the left side of the slide block 16, abutting between the nut 29 and the mounting plate 31, a fixing screw 32 for fixed connection to the rear side of the mounting plate 31, a motor 33 for fixed connection to the left side of the mounting plate 31, a chip removal cover 34 for fixed connection to the front side of the motor 33, a roughing tool 35 for fixed connection to the output end of the motor 33, and an adjusting block 17 for threaded connection to the screw 25. 17 is fixed to the slide block 16. The mounting block 18 is bolted to the slide block 16 and can rotate around the slide block 16. The threaded part of the adjusting screw 19 is screwed into the adjusting block 17, and the screw head presses against the spring 20. The more the adjusting screw 19 is screwed in, the greater the elastic force of the spring 20, and the greater the upward force on the mounting block 18. Under the force of the spring 20, the mounting block 18 rotates counterclockwise around the slide block 16. The upper cylinder 22 is fixed to the mounting block 18, and the lower cylinder 22 is fixed to the adjusting block 17. The adjusting screw 23 is screwed into the cylinder 22 and locked with the nut 24. When the piston rod of the cylinder 22 extends, it will hit the adjusting block 17 or the mounting block 18. Since the adjusting block 17 is fixed, According to the relationship between action and reaction forces, the mounting block 18 is subjected to a downward force, and the slide 16 rotates clockwise. When cutting the edge banding, the contour disc 36 needs to press against the surface of the wooden board as a reference for cutting the edge banding. If the pressure is too high when the wooden board enters, it may damage the front end of the wooden board; if the pressure is too low, it cannot be properly contoured. In this device, the force pressing the wooden board when it enters is relatively small, and a larger force is used to press the wooden board after it enters. The force generated by the spring 20 and the cylinder 22 can make the mounting block 18 rotate counterclockwise and clockwise around the slide 16, respectively. The counterclockwise force is the force pressing the wooden board. The contour disc 36 is mounted on the mounting block 18. The greater the elastic force of the spring 20, the greater the force of the contour disc 36 pressing the wood, because the output direction of the cylinder 22 is opposite to that of the spring 20.Therefore, the output force of cylinder 1 22 and spring 3 20 can be adjusted to adjust the appropriate force of the conforming disc 36 pressing the wooden board. The motor 33 is installed on the mounting plate 31, and the locking screw 28 is fixed on the slide 16. The mounting plate 31 is installed and fixed on the slide 16 by nut 3 29. The function of fixing screw 1 30 and fixing screw 2 32 is to position the mounting plate 31. The steps to remove screw 1 5 are to first loosen nut 3 29, move the large round hole of the mounting plate 31 below nut 3 29, and then take out the mounting plate 31. During installation... Nut 329 is inserted through the large round hole. Mounting plate 31 is positioned, and finally, nut 329 is tightened. The position of the contour disc 36 is adjusted so that it is close to the chip removal cover 34. The smaller the gap between them, the better; it should not touch the chip removal cover 34. This ensures that the gap is small enough that the cutting material is less likely to fly out from around the chip removal cover 34. The contour disc 36 and the chip removal cover 34 surround the roughing tool 35, leaving only a gap at the edge where the sealing strip is cut. During chip removal, air enters from this gap and exits through the round hole of the chip removal cover 34, thus directing the cutting material out along the chip removal direction.

[0049] Reference Figure 1 - Figure 19 The feed assembly includes two connecting rods 44, which are fixedly connected to the rear side of the slide block 16. A connecting seat 42 is fixedly connected between the rear ends of the two connecting rods 44. A screw 40 is rotatably connected inside the connecting seat 42. A nut 43 is threadedly connected to the outside of the screw 40. A retaining ring 45 is slidably connected to the outside of the screw 40. The retaining ring 45 and the screw 40 are fixedly connected by a cotter pin 46. A counter 41 is fixedly connected to the outside of the screw 40. A handle 52 is fixedly connected to the rear end of the screw 40. The two connecting rods 44 are mounted and fixed on the slide block 16, and the connecting seat 42 is fixed on the connecting rods 44. The connection between the retaining ring 45 and the screw 40 is completed by inserting the cotter pin 46 into the holes of both. The screw 40 and the slide 16 are connected by threads. The nut 43 is screwed into the thread of the screw 40. The connecting seat 42 is between the nut 43 and the cotter pin 46, so the screw 40 is axially positioned. Adjust the nut 43 to preload the connecting seat 42. The pressure should be appropriate to ensure that the screw 40 can rotate smoothly. When the handle 52 is turned, the slide 16 moves along the guide rod 15 to adjust the horizontal position of the blade and the sealing strip. The screw 40 is externally rotatably connected to the inside of the slide 16, so that the slide 16 can move.

[0050] Working principle: When using this device, the pressure of the contour disc 36 can be controlled by adjusting the output force of spring 3 20 and cylinder 1 22. Even without cylinder 1 22, adjusting the compression of spring 3 20 alone can adjust the force. The difference is that with cylinder 1 22, adjusting its air pressure adjusts the pressure, making operation very convenient. The upper and lower buffer components allow for more precise adjustment. By turning handle 1 12, the blade contacts the edge banding tape, and then turning adjusting screw 2 21 adjusts the outer diameter of the contour disc 36 to align with the surface of the wooden board. After ensuring the surface is in contact, finally tighten the adjusting screw 21. Then, turn the handle 27 to make the lower end face of the screw 25 contact the mounting block 18, or turn the handle 27 to make the lower end face of the screw 25 separate from the surface of the mounting block 18 by a certain distance. This distance is the cutting amount, which can be read from the counter 26. Because the tool is stationary, the outer diameter of the contour disc 36 is always in contact with the wood board. Therefore, the closer the outer diameter of the contour disc 36 is to the cutting edge, the greater the cutting amount, and vice versa. This adjusts the contact distance between the cutting edge and the edge banding tape. With the cutting amount adjusted, turn the adjusting screw 47 to move it upward a small distance; this distance is the preload. At this point, the outer diameter of the copying disc 36 should be lower than the surface of the wooden board. Next, turn the nut 48 downward to compress the spring 49, increasing the preload; conversely, turning it downward decreases the preload. Then, control the cylinder 2 49 to work, extending its piston rod to press against the top plate 50. At this point, the upper and lower components move away in opposite directions. The lower component touches the lower limit block 3 and stops moving downward, while the upper component continues to move upward until the cylinder 2 49... Once the process is complete, work can begin. The chip removal cover 34 is made of metal and is connected to the bracket 1 through other parts, so static electricity does not easily accumulate on it. During chip removal, it will not attract the cuttings due to its own static electricity, thus preventing the cuttings from falling onto the wooden board and being pressed by the contour disc 36. This would cause the contour disc 36 to be raised, resulting in uneven contouring of the edge banding tape. The outer diameter of the contour disc 36 is larger than that of other products on the market, and it can wrap around the chip removal cover 34. Because of the increased outer diameter, the wooden board will enter more smoothly, and the operation will be more precise and convenient.
