Description

Technical Field

[0001] The invention belongs to the technical field of furniture, and in particular relates to an edge processing device for furniture panels. Background Art

[0002] When the board is edged, there is often a problem that only the tail end of the board is sealed or the entire edge is not sealed. These are caused by unstable feeding belt. The edge banding belt is squeezed and fed by the feeding wheel and the transmission wheel. The spacing between the two wheels is required to be between 3-4mm.

[0003] If the distance between the two wheels is too large, the two wheels will not fit together, resulting in insufficient friction and the edge banding cannot be delivered stably; if the wheelbase is too small, the friction will increase, which will hinder the normal delivery of the edge banding. Therefore, the distance between the two wheels needs to be kept within a reasonable range and should not fluctuate greatly. At the same time, if the feeding wheel and the transmission wheel are not flexible, slippage may occur during feeding.

[0004] The distance between the transmission wheel and the belt feed wheel can be adjusted by springs and bolts, but during production, the transmission wheel and the belt feed wheel are pressed against the plate for a long time, and after long-term stress, the distance between the two wheels will fluctuate, and the rotation of the two wheels may also become stuck. This is an inevitable defect of the rolling conveying method, which may lead to unstable belt conveying and edge quality problems. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a furniture board edge processing device, which at least partially solves the above problem.

[0007] Furthermore, a belt conveying wheel and a transmission wheel are rotatably provided on the edge banding strip conveying plate, and a belt conveying motor is connected to the lower end of the transmission wheel; Furthermore, a material roll fixing disk is provided at the rear end of the edge banding strip conveying plate.

[0008] Furthermore, a plurality of groups of bottom plates are provided at the lower end of the edge banding strip conveying plate, and a symmetrically arranged forced conveying mechanism is slidably arranged on each group of the bottom plates. The number of the forced conveying mechanisms matches the number of the bottom plates. A transmission shaft passes through the center of the forced conveying mechanism, and a clamping motor is provided at the end of the transmission shaft.

[0009] Furthermore, the forced conveying mechanism comprises a rectangular frame, the rectangular frame slides on the bottom plate, an upper rack is provided on the inner side of the upper wall of the rectangular frame, and a lower rack is provided on the inner side of the lower wall of the rectangular frame; Furthermore, a half gear is provided in the middle of the rectangular frame, the transmission shaft passes through the center of the half gear, and the half gear can be meshed with the upper rack and the lower rack respectively; Furthermore, a clamping frame is installed above the rectangular frame through a connecting plate, and the clamping frame is slidably arranged in the connecting plate through a compression spring, and a grooved clamping plate is provided on the side of the clamping frame close to the edge strip conveying plate, and a guide column is provided on the side of the clamping frame away from the edge strip conveying plate; Furthermore, a guide rail plate is provided at the rear end of the clamping frame, the guide rail plate is fixedly connected to the bottom plate, straight rails are symmetrically provided on the upper wall of the guide rail plate, a disengagement rail is provided at one end of the straight rail, a reset rail is provided at the end of the straight rail away from the disengagement rail, and the disengagement rail is connected to the reset rail to form a closed loop; Furthermore, the guide post can slide along a path formed by the straight rail, the breakaway rail and the reset rail on the guide rail plate.

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0016] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0017] like Figure 1 As shown, an embodiment of the present invention proposes a furniture board edge processing device, including a conveyor table 1, which is used to convey and fix the board to be edged, so as to complete the edged treatment during the horizontal movement of the board. The side wall of the conveyor table 1 is provided with an edge strip conveyor plate 4, and the edge strip conveyor plate 4 can guide the strip to the side wall of the board. In order to make the strip fit better with the board, the edge strip conveyor plate 4 and the conveyor table 1 are arranged at a certain acute angle.

[0018] In order to press the strip and fit it to the side wall of the plate, the side wall of the conveyor platform 1 is provided with a pressing roller 3, which presses the strip to fit the strip and the plate. During the pressing, the surface of the strip will be coated with glue, which is not shown in the attached drawings. The middle array of the conveyor platform 1 is provided with a conveyor roller 2, which is connected to an external power mechanism to achieve rotation.

[0019] Combination Figure 2 As shown, a tape feed wheel 5 and a transmission wheel 9 are rotatably provided on the edge banding strip conveying plate 4. There are multiple groups of tape feed wheels 5 arrayed, and the transmission wheel 9 is close to the conveying platform 1 and is arranged in cooperation with the current tape feed wheel 5. The distance between the transmission wheel 9 and the tape feed wheel 5 can be adjusted, so as to adjust the friction force applied to the strip during conveying. The tightness of the transmission wheel 9 can be adjusted by a spring, and the specific structure is not shown here. A strip conveying motor 8 is connected to the lower end of the transmission wheel 9, and the strip conveying motor 8 drives the transmission wheel 9 to rotate. When the transmission wheel 9 rotates, it provides friction to the surface of the strip, so as to drive the strip to move toward the conveying platform 1.

[0020] A material roll fixing disk 6 is provided at the rear end of the edge banding strip conveying plate 4. The edge banding strip coil is fixed on the rotating shaft in the middle of the material roll fixing disk 6, and the strip is guided and clamped by the tape feeding wheel 5 on the edge banding strip conveying plate 4, and finally conveyed to the conveying platform 1 by the transmission wheel 9.

[0021] The lower end of the edge strip conveying plate 4 is provided with a plurality of bottom plates 7, Figure 3 and Figure 4 As shown, a symmetrically arranged forced conveying mechanism 11 is slidably arranged on each group of bottom plates 7, and the number of forced conveying mechanisms 11 is adapted to the number of bottom plates 7. A transmission shaft 10 runs through the center of the forced conveying mechanism 11, and a clamping motor 12 is arranged at the end of the transmission shaft 10. The clamping motor 12 drives the forced conveying mechanism 11 to move back and forth, and the forced conveying mechanism 11 clamps the strip, follows the strip to move to a set position, and then releases the strip, and then returns to the initial position. In the process of clamping the strip, the strip and the forced conveying mechanism 11 will not roll relative to each other, so as to prevent the strip from slipping or unstable feeding, etc., to overcome the defects of the rolling conveying method, and multiple groups of forced conveying mechanisms 11 are configured for staggered clamping. When one group of forced conveying mechanisms 11 clamps the strip, the other group of forced conveying mechanisms 11 remains in a loose state to prevent a vacuum period of clamping.

[0022] The forced conveying mechanism 11 includes a rectangular frame 13, which slides on the bottom plate 7. An upper rack 19 is provided on the inner side of the upper wall of the rectangular frame 13, and a lower rack 20 is provided on the inner side of the lower wall of the rectangular frame 13. The module and tooth height of the upper rack 19 and the lower rack 20 are set the same.

[0023] A half gear 14 is provided in the middle of the rectangular frame 13, and the transmission shaft 10 passes through the center of the half gear 14. Half of the half gear 14 is distributed with meshing teeth, and the other half is a smooth arc shape. The half gear 14 can mesh with the upper rack 19 and the lower rack 20 respectively. When the half gear 14 meshes with the upper rack 19 for transmission, the rectangular frame 13 moves horizontally in one direction. When the half gear 14 meshes with the lower rack 20 for transmission, the rectangular frame 13 moves in the opposite direction.

[0024] A clamping frame 16 is mounted above the rectangular frame 13 through a connecting plate 17. Figure 5 As shown, the clamping frame 16 is slidably arranged in the connecting plate 17 through a compression spring 18, and a grooved clamping plate 21 is provided on the side of the clamping frame 16 close to the edge strip conveying plate 4. The compression spring 18 always applies pressure to the clamping frame 16 in the direction of the strip, so that the grooved clamping plate 21 is pressed against the strip. The groove holes on the grooved clamping plate 21 can increase the friction force on the surface of the strip and improve the stability of clamping and conveying. A guide column 22 is provided on the side of the clamping frame 16 away from the edge strip conveying plate 4.

[0025] like Figure 4 and Figure 6 As shown, a guide rail plate 15 is provided at the tail end of the clamping frame 16, and the guide rail plate 15 is fixedly connected to the base plate 7. Straight rails 23 are symmetrically provided on the upper wall of the guide rail plate 15, and a breakaway rail 24 is provided at one end of the straight rail 23. A reset rail 25 is provided at the end of the straight rail 23 away from the breakaway rail 24, and the breakaway rail 24 is connected to the reset rail 25 to form a closed loop.

[0026] The guide post 22 can slide along the path formed by the straight rail 23, the breakaway rail 24 and the reset rail 25 on the guide rail plate 15. Preferably, the camber curve of the reset rail 25 is smaller than that of the breakaway rail 24 so that the guide post 22 can transition from the breakaway rail 24 to the reset rail 25.

[0027] like Figure 3 and Figure 7 As shown, the upper wall of the bottom plate 7 is symmetrically provided with a slide groove 26, the outer side of the slide groove 26 is symmetrically provided with a support frame 27, and the middle part of the upper wall of the bottom plate 7 is provided with a flange 28; the rectangular frame 13 is slidably arranged in the slide groove 26, and the guide plate 15 is fixed on the support frame 27.

[0028] During specific operation, the edge banding tape coil is fixed on the central axis of the material coil fixing disk 6, and then one end of the tape is passed through the tape feeding wheel 5 on the edge banding strip conveying plate 4 in sequence until the tape is clamped in the gap between the tape feeding wheel 5 at the end and the transmission wheel 9.

[0029] Then the plate is placed on the conveying roller 2 on the conveying platform 1, and the external power mechanism drives the conveying roller 2 to rotate, and when the conveying roller 2 rotates, it will synchronously drive the plate to move horizontally.

[0030] Start the strip conveying motor 8, which drives the driving wheel 9 to rotate. The driving wheel 9 provides friction to the surface of the strip to move the strip forward. During this process, the side wall of the strip will be coated with glue by the gluing mechanism (the gluing mechanism is not shown in the attached figure). When the strip contacts the side edge of the plate, the pressing roller 3 presses the strip and the side wall of the plate. Since the surface of the strip has been coated with glue, the strip can now bond with the side wall of the plate.

[0031] During the operation, in order to prevent the driving wheel 9 and the belt feeding wheel 5 from slipping relative to the belt material and causing unstable feeding, the forced conveying mechanism 11 is started to forcefully clamp and convey the belt material.

[0032] When the forced conveying mechanism 11 starts working, the clamping motor 12 needs to be started first. The clamping motor 12 drives the half gear 14 to rotate through the transmission shaft 10. When the half gear 14 rotates, it will mesh with the upper rack 19 and the lower rack 20 for transmission.

[0033] When the half gear 14 is meshed with the upper rack 19, the rectangular frame 13 moves toward the conveyor platform 1. At this time, the guide column 22 is in the straight rail 23 close to one side of the rectangular frame 13, so that the grooved clamps 21 on the clamping frames 16 on both sides are close to each other, and the grooved clamps 21 are close to each other under the action of the clamping spring 18, and the strip is clamped together to prevent it from loosening. When the rectangular frame 13 moves, it will synchronously drive the grooved clamps 21 to move, and the grooved clamps 21 on both sides will force the strip to move a distance, which is the same as the length of the straight rail 23.

[0034] When the guide post 22 moves to the end of the straight rail 23, the guide post 22 will move along the arc of the departure rail 24 in the direction away from the side wall of the rectangular frame 13, so that the grooved clamps 21 on both sides are gradually separated, and the strips in the grooved clamps 21 on both sides are no longer subjected to the clamping force. At this time, the forced conveying mechanism 11 can no longer force the strip to move, and the remaining forced conveying mechanisms 11 repeat the above-mentioned actions of the forced conveying mechanism 11, taking over the clamping of the strip, thereby continuously clamping the strip to move.

[0035] When the guide post 22 moves to the disengagement rail 24, it will enter the reset rail 25. At this time, the half gear 14 has also rotated to the lower rack 20 and meshed with the lower rack 20. When the half gear 14 continues to rotate, the rectangular frame 13 will move in the opposite direction, and the guide post 22 will overcome the pressure of the compression spring 18 and enter the outer straight rail 23 from the reset rail 25. The guide post 22 slides along the straight rail 23 until it enters the disengagement rail 24 and the reset rail 25 at the other end of the guide rail plate 15 again, thereby forming a closed-loop path and moving back and forth along this path under the action of the half gear 14, thereby realizing the reciprocating clamping, loosening and re-clamping of the strip, and continuously driving the strip to move.

[0036] Multiple groups of forced conveying mechanisms 11 can take over the clamping of the strip, so that the strip is always subjected to a forced clamping force. Under the action of this clamping force, the strip continues to feed to the conveying platform 1, plays an auxiliary feeding role for the driving wheel 9, and makes up for the defects of the rolling feeding method of the driving wheel 9.

[0037] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0038] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
