Description

Technical Field

[0001] The utility model relates to the technical field of edge banding machines, in particular to an automatic edge banding machine used for furniture wood processing. Background Art

[0002] Edge banding machine is a commonly used woodworking machine, which is mainly used to stick edge banding strips on the edges of wooden boards to make the edges of the boards smoother and more beautiful. It is widely used in the process of wooden board processing.

[0003] The working principle of the edge banding machine is to put the wooden board on the conveyor belt, and the side of the wooden board that needs to be edge banded contacts the side of the edge banding machine and the glue guide roller. The conveyor belt drives the wooden board to move, and the glue guide roller rotates to apply glue to one side of the wooden board. After the part coated with glue contacts the edge banding strip, the edge banding strip is clamped by the wooden board and the limit seat on the top side of the edge banding machine, and the edge banding strip is bonded to the wooden board. For example, a fully automatic edge banding machine disclosed in Chinese patent CN218802939U, the fully automatic edge banding machine, by setting an infrared lamp to heat the edge banding tape, ensures the adhesion of the edge banding tape, avoids the problem of the edge banding tape falling off due to reduced adhesion in winter, and the infrared heating has high thermal efficiency, improves the energy utilization efficiency, and is energy-saving and environmentally friendly; by setting a telescopic rod and a second cutting knife to achieve the cutting of the excess part of the edge banding tape, the workload of the staff is effectively reduced and the degree of automation of the device is improved. However, while solving the problem, the existing fully automatic edge banding machine has the following defects:

[0004] The limiting roller group of the existing fully automatic edge banding machine is generally parallel to the limiting seat, that is, the conveying direction of the limiting roller group is consistent with the conveying direction of the conveyor belt. Therefore, when the wooden board moves above the conveyor belt, the clamping force of the wooden board and the limiting seat on the edge banding strip is often insufficient, resulting in insufficient firmness of the edge banding strip bonded to the wooden board, and easy problems of warping or unevenness. The existing solution is usually that when banding the edge, the carpenter gives the wooden board a thrust in the direction of the limiting seat, so that the wooden board pushes the edge banding strip, so that the edge banding strip slides tightly on the surface of the limiting seat, thereby solving the problems of insufficient firmness and easy warping or unevenness. However, this solution is more laborious. Utility Model Content

[0024] The present utility model provides an automatic edge banding machine for furniture wood processing.

[0025] Embodiment 1:

[0026] As Figure 1-2 shown, it includes an edge banding device 1. A workbench 11 is fixedly connected to the top of the edge banding device 1. A hole slot 12 is opened on the top of the workbench 11. A conveyor belt 13 is fixedly installed inside the edge banding device 1. A limiting seat 2 is fixedly connected to one side of the top of the workbench 11. A limiting plate 21 is fixedly connected to one side of the bottom of the limiting seat 2 close to the conveyor belt 13. The limiting plate 21 is used to limit and support the board. A lifting plate 3 is slidably connected to the inside of the limiting seat 2 in a liftable manner. One side of the bottom of the lifting plate 3 is rotatably connected with a plurality of pressure rollers 4. The lifting plate 3 can adjust the height of the plurality of pressure rollers 4 by sliding up and down, so as to adjust the distance between the pressure rollers 4 and the conveyor belt 13, which can be applicable to boards of different thicknesses. And the included angle between the pressure rollers 4 and the conveying direction of the conveyor belt 13 is less than ninety degrees. As Figure 2 shown, the included angle a is less than ninety degrees. In this way, when the conveyor belt 13 conveys the board, the pressure rollers 4 rotate, and can give the board a force towards the limiting plate 21 direction, which is equivalent to the thrust given by a person to the board.

[0027] Specifically, positioning grooves 22 are opened on both sides of the limiting seat 2. Positioning plates 31 are fixedly connected to both sides of the lifting plate 3. The positioning plates 31 are slidably connected in the positioning grooves 22. A vertical screw rod 23 is rotatably connected to the top of the limiting seat 2. A threaded hole 32 is opened on the top of the lifting plate 3. The screw rod 23 is threadedly connected in the threaded hole 32. The number of the screw rod 23 and the threaded hole 32 is at least two, which can provide stable support for the lifting plate 3. By rotating the screw rod 23, the lifting plate 3 can be lifted and lowered, so as to achieve the purpose of adjusting the height of the pressure rollers 4.

[0028] Embodiment 2:

[0029] When adjusting the height of the pressing roller 4 of the existing edge banding machine, it is usually necessary to separately adjust the adjusting screws on both sides of the edge banding machine to lift or lower the pressing roller 4 as a whole, which is inconvenient to operate. To solve this problem, as Figure 1-3 shown, on the basis of Embodiment 1, a worm gear 24 is fixedly connected to the top end of the screw rod 23, and a plurality of first bearing seats 25 are fixedly connected to the top of the limit seat 2. A worm 26 is rotatably connected inside the bearing seat 25. The worm 26 meshes with the worm gear 24, and one end of the worm 26 is fixedly connected to a first turntable 27. By rotating the worm 26 through the first turntable 27, the worm gear 24 can be driven to rotate, thereby driving the screw rod 23 to rotate in the threaded hole 32, achieving the purpose of raising or lowering the lifting plate 3. It is not necessary to separately operate each screw rod 23 to rotate, which is convenient and fast. Moreover, the combination of the worm gear 24 and the worm 26 has self-locking property, making the support for the lifting plate 3 more stable.

[0030] Embodiment 3:

[0031] For plates with different weights and different sizes, different thrusts need to be provided to the plates. If the force is too small, the edge banding may curl or be uneven, and if the force is too large, the surface of the plate may be damaged. To solve this problem, as Figure 4-5 shown, on the basis of Embodiment 1 or Embodiment 2, a plurality of through holes 33 are opened at the top of the lifting plate 3. A rotating shaft 41 is rotatably connected to the axis of the pressing roller 4. The pressing roller 4 can rotate around the rotating shaft 41. One end of the rotating shaft 41 is fixedly connected to a positioning seat 42. A positioning shaft 43 is fixedly connected to the top of the positioning seat 42. The positioning shaft 43 is rotatably connected in the through hole 33, enabling the positioning seat 42 to rotate through the positioning shaft 43, thereby adjusting the angle of the pressing roller 4. The top end of the positioning shaft 43 is fixedly connected with a limit block 44 to prevent the positioning shaft 43 from falling off. A plurality of second bearing seats 34 are fixedly connected to the bottom of the lifting plate 3. A lead screw 35 is rotatably connected inside the second bearing seat 34. A plurality of moving seats 5 are threadedly connected to the outer surface of the lead screw 35. A limit groove 36 is opened at the bottom of the lifting plate 3. One side of the moving seat 5 is fixedly connected with a limit rod 52. The limit rod 52 is slidably connected in the limit groove 36. When the lead screw 35 is rotated, since the limit rod 52 is restricted by the limit groove 36, the moving seat 5 will not rotate with the lead screw 35. Therefore, the lead screw 35 can rotate inside the moving seat 5, enabling the moving seat 5 to move on the surface of the lead screw 35. The top end of the moving seat 5 is fixedly connected with a sliding rod 51. One side of the positioning seat 42 is fixedly connected with a push plate 45. A sliding groove 46 is opened at the top of the push plate 45. The sliding rod 51 is slidably connected in the sliding groove 46. One end of the lead screw 35 is fixedly connected with a second turntable 37. By rotating the lead screw 35 through the second turntable 37, the moving seat 5 is moved, so that the sliding rod 51 can push the push plate 45 to move. At this time, the positioning seat 42 will rotate through the positioning shaft 43, thereby adjusting the angle of the pressing roller 4.

[0032] The working principle of the present utility model is as follows: When in use, glue is applied to the side of the board. After the edge banding strip is adhered to the glued part, the conveyor belt 13 conveys the board. One side of the board with the edge banding strip adhered is attached to one side of the limiting plate 21. When passing through the pressing roller 4, the pressing roller 4 rolls. The inclined pressing roller 4 can give the board a thrust force towards the limiting plate 21, so that the board is tightly attached to the side of the limiting plate 21, providing sufficient clamping force for the edge banding strip. Thus, before the glue cures, the edge banding strip can be closely attached to the board, so that after the glue cools and cures, the edge banding strip will not have the problem of warping.

[0033] Compared with the prior art, the present utility model has the following beneficial effects relative to the prior art:

[0034] 1. By setting the inclined pressing roller 4, the angle between the pressing roller 4 and the conveying direction of the conveyor belt 13 is less than ninety degrees. Thus, when the conveyor belt 13 conveys the board, the pressing roller 4 rotates, and can give the board a force towards the limiting plate 21, which is equivalent to the thrust force given by a person to the board, so that the limiting plate 21 and the board can provide sufficient clamping force for the edge banding strip, ensuring that the edge banding strip will not have the problems of warping or unevenness, and there is no need for manual application of thrust force, thus saving manpower.

[0035] 2. When adjusting the height of the pressing roller 4, by rotating the worm 26 through the first turntable 27, all the worm wheels 24 can be driven to rotate, thereby driving all the screws 23 to rotate in the threaded holes 32, achieving the purpose of raising or lowering the lifting plate 3. It is convenient and fast, and the combination of the worm wheel 24 and the worm 26 has self-locking property, making the support for the lifting plate 3 more stable.

[0036] 3. By rotating the lead screw 35 through the second turntable 37, multiple moving seats 5 can be moved, enabling the sliding rod 51 to push the push plate 45 to move, making the positioning seat 42 rotate, thereby adjusting the inclination angle of the pressing roller 4. Thus, when conveying the board, the thrust force of the pressing roller 4 on the board can be adjusted, so as to be applicable to different boards, improving the practicability.
