Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing equipment, specifically to an edge banding machine. Background Technology

[0002] An edge banding machine is a commonly used woodworking machine suitable for edge banding medium-density fiberboard, plywood, solid wood boards, particleboard, polymer door panels, plywood, etc. First, the molten adhesive is heated and melted, then applied to the edge of the board, and finally the edge banding strip is fixed to the edge of the board. When edge banding the board, it is usually necessary to trim off any excess edge banding strip from the board edge to ensure that the edge banding strip can perfectly fit the edge of the board.

[0003] The edge banding table of existing edge banding machines is usually of a fixed specification. When the width of the board being processed matches the width of the edge banding table, the edge trimming knife set on the edge of the edge banding table can keep the board stable and prevent it from deviating when trimming the edge. However, when the width of the board being processed is narrower than the width of the edge banding table, the resistance generated when the edge trimming knife cuts the excess edge banding strip can easily cause uneven force on both sides of the board and cause it to deviate. On the one hand, this will prevent the edge trimming knife from achieving effective trimming and cutting, and on the other hand, it will also affect the conveying of the board. In severe cases, it may even cause multiple boards to accumulate and block on the conveying mechanism of the edge banding machine, resulting in product loss and equipment loss.

[0004] This shows that existing technologies still have certain shortcomings. Utility Model Content

[0005] The purpose of this invention is to provide an edge banding machine that solves the problem that existing traditional edge banding machines cannot effectively trim narrower boards.

[0006] To achieve the above objectives, this utility model provides an edge banding machine, which includes an edge banding table and an upper pressure beam disposed above the edge banding table. The edge banding table is provided with a conveying mechanism for conveying the sheet material. A pressing mechanism is disposed at the lower part of the upper pressure beam. The edge banding table is also provided with a support mechanism. In the vertical direction, the pressing mechanism and the support mechanism are disposed opposite to each other on the upper and lower sides of the conveying mechanism. In the vertical direction, the pressing mechanism can move relative to the upper pressure beam and / or the support mechanism can move up and down relative to the edge banding table.

[0007] It also includes a trimming knife and a side support mechanism. The trimming knife and the side support mechanism are arranged opposite to each other on both sides of the conveying mechanism in a direction perpendicular to the conveying direction of the conveying mechanism, and the trimming knife and / or the side support mechanism can extend and retract relative to the conveying mechanism in a direction perpendicular to the conveying direction of the conveying mechanism.

[0008] In the above solution, the cooperation of the clamping mechanism and the supporting mechanism can clamp the side of the board to be trimmed during the board conveying and trimming process, preventing the board from shifting or deflecting in the direction perpendicular to its conveying direction. Simultaneously, the support mechanism on the other side of the board provides support and limitation, ensuring that even narrow boards maintain stable posture during edge banding and trimming, thus guaranteeing the edge banding effect. Furthermore, the clamping force and clamping range of the clamping and supporting mechanisms on the board can be flexibly adjusted by the lifting and lowering movement of the clamping mechanism relative to the upper pressure beam and / or the lifting and lowering movement of the supporting mechanism relative to the edge banding table. This adapts to the processing needs of boards of different thicknesses, expanding the applicability of the edge banding machine in this application.

[0009] As a preferred embodiment of this application, a ranging component is also included, which is disposed at the entrance of the conveying mechanism and includes a first ranging element for detecting the width of the plate and a second ranging element for detecting the thickness of the plate.

[0010] In the above scheme, measuring the thickness and width of the plate using the first and second measuring devices facilitates the corresponding adjustment of the positions of the support mechanism, clamping mechanism, side support mechanism, and trimming knife, which helps to ensure trimming accuracy.

[0011] In a preferred embodiment of this application, the clamping mechanism includes a plurality of clamping wheels arranged along the conveying direction of the conveying mechanism, the support mechanism includes a plurality of support wheels arranged along the conveying direction of the conveying mechanism, and the side support mechanism includes a plurality of side support wheels arranged along the conveying direction of the conveying mechanism; one or more trimming blades are provided, and the plurality of support wheels are divided into one or more groups corresponding to the number of trimming blades, and each group of support wheels is arranged in front of the corresponding trimming blade along the conveying direction of the conveying mechanism.

[0012] In the above scheme, the pressure roller, side support roller, and support roller can all rotate with the movement of the board, thereby limiting the board while reducing the resistance to the board conveying, which is conducive to ensuring the efficiency of the board edge banding process. At the same time, in the above scheme, the support roller is only set in front of the trimming knife to support and limit the board when the board is trimmed. The conveying section after the board has completely passed the trimming knife is not limited and supported by the support roller, further reducing the conveying resistance and improving the processing efficiency.

[0013] In a preferred embodiment of this application, the pressure wheel, the support wheel, and the side support wheel all include a wheel body and an elastic rim covering the outside of the wheel body.

[0014] In the above solution, compared with directly using a rigid wheel body, using an elastic wheel rim can reduce the pressure of the pressure wheel and support wheel on the plate, thereby avoiding damage to the surface of the plate.

[0015] In a preferred embodiment of this application, the side support mechanism further includes multiple side support rods, each of which is corresponding to a side support wheel. The side support wheel is located at the end of the side support rod facing the conveying mechanism. The side support mechanism also includes a side support drive assembly connected to the side support rods, which drives the multiple side support rods to extend and retract synchronously or asynchronously.

[0016] The above structure allows for the synchronous extension and retraction of the side support rods via the side support drive assembly, making it suitable for processing boards with regular edge structures. The asynchronous extension and retraction of the side support rods via the side support drive assembly allows it to be used for processing boards with irregular edge structures, further enhancing the versatility of the edge banding machine in this application.

[0017] In a preferred embodiment of this application, the side support drive assembly includes a plurality of drive cylinders, which are connected to the side support rods respectively. The drive cylinders drive the side support rods connected to them and cause the side support wheels on the side support rods to extend and retract.

[0018] In the above scheme, the drive cylinder can directly output linear motion, and can respond in a timely manner to changes in the edge shape of the plate when dealing with irregular edge structures. The drive side support mechanism provides stable and effective side support for the plate.

[0019] In a preferred embodiment of this application, the clamping mechanism further includes a first connecting frame, which is the same length as the conveying mechanism along the conveying direction, and a plurality of clamping wheels are mounted on the first connecting frame; the support mechanism further includes a second connecting frame, which is provided with one or more sets of support wheels corresponding to the number of sets of support wheels, and each set of support wheels is mounted on the second connecting frame corresponding to it.

[0020] The above structure allows for flexible adjustment of the arrangement of the clamping rollers on the first connecting frame and the arrangement of the support rollers on the second connecting frame according to actual needs. This allows for adaptation to / avoidance of protruding structures on irregularly shaped plates, and also facilitates the maintenance and replacement of the clamping rollers and support rollers.

[0021] As a preferred embodiment of this application, it further includes a clamping adjustment drive and a support adjustment drive. The clamping adjustment drive is driven to the first connecting frame to drive the first connecting frame to move the clamping wheel up and down. One or more support adjustment drives are provided corresponding to the second connecting frame. The support adjustment drive is driven to the second connecting frame to drive the second connecting frame and the support wheel installed on the second connecting frame to move up and down.

[0022] As a preferred embodiment of this application, it also includes side curtains, one or more of which are provided corresponding to the trimming knife. The side curtains are disposed between the trimming knife and the pressing wheel in a direction perpendicular to the conveying direction of the conveying mechanism.

[0023] In the above solution, by setting up a side curtain, excess edge banding residue and solidified adhesive residue cut off by the edge trimming knife during the trimming process can be prevented from falling between the clamping roller and the board and causing damage to the board surface.

[0024] In a preferred embodiment of this application, the height of the lower free end of the side curtain is not higher than the height of the upper surface of the board in the vertical direction.

[0025] This setup ensures close contact between the side curtain and the board surface, preventing residual edge banding, sawdust, and glue residue from leaking through the gap between the side curtain and the board surface. Attached Figure Description

[0034] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0035] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0036] like Figures 1-2 As shown, this application provides an edge banding machine, which includes an edge banding table 2 and an upper pressure beam 1 disposed above the edge banding table 2. The edge banding table 2 is provided with a conveying mechanism 4 for conveying sheet metal. A pressing mechanism 11 is disposed at the lower part of the upper pressure beam 1. The edge banding table 2 is also provided with a support mechanism 22. Vertically, the pressing mechanism 11 and the support mechanism 22 are disposed opposite each other on the upper and lower sides of the conveying mechanism 4, with a gap between them allowing the sheet metal to pass through. As a preferred embodiment of this application, vertically, the pressing mechanism 11 can move relative to the upper pressure beam 1 and / or the support mechanism 22 can move up and down relative to the edge banding table 2, thereby adjusting the size of the aforementioned gap to accommodate sheet metal of different thicknesses. Further, referring to... Figure 2 As shown, the edge banding machine in this application also includes an edge trimming knife 21 and a side support mechanism 23. The edge trimming knife 21 and the side support mechanism 23 are arranged opposite to each other on both sides of the conveying mechanism 4 in a direction perpendicular to the conveying direction of the conveying mechanism 4. Also, as a preferred embodiment of this application, the edge trimming knife 21 and / or the side support mechanism 23 can extend and retract relative to the conveying mechanism 4 in a direction perpendicular to the conveying direction of the conveying mechanism 4.

[0037] In the above scheme, the clamping mechanism 11 and the supporting mechanism 22 work together to clamp the side of the board to be trimmed during the board conveying and trimming process, preventing the board from shifting or deflecting in the direction perpendicular to its conveying direction. Simultaneously, the side support mechanism 23 provides support and limiting on the other side of the board, ensuring that even narrow boards maintain stable posture during edge banding and trimming, thus guaranteeing the edge banding effect. Furthermore, the movement of the trimming knife 21 and / or the side support mechanism 23 relative to the edge banding table 2 can flexibly adjust to the processing needs of boards of different widths, thus expanding the applicability of the edge banding machine in this application.

[0038] As a preferred embodiment of this application, refer to Figure 1 and Figure 2As shown, the clamping mechanism 11 includes multiple clamping wheels 112 arranged along the conveying direction of the conveying mechanism 4, the support mechanism 22 includes multiple support wheels 222 arranged along the conveying direction of the conveying mechanism 4, and the side support mechanism 23 includes multiple side support wheels 231 arranged along the conveying direction of the conveying mechanism 4. One or more trimming blades 21 are provided, and the multiple support wheels 222 are divided into one or more groups corresponding to the number of trimming blades 21. Each group of support wheels 222 is arranged in front of the corresponding trimming blade 21 along the conveying direction of the conveying mechanism 4. In the above scheme, the pressing wheel 112, the support wheel 222, and the side support wheel 231 are used to contact the board. The pressing wheel 112, the side support wheel 231, and the support wheel 222 can all rotate with the movement of the board, thereby limiting the board while reducing the resistance to the board conveying, which is conducive to ensuring the efficiency of the board edge banding process. At the same time, in the above scheme, the support wheel 222 is only set in front of the trimming knife 21 to support and limit the board when the board is trimmed. The conveying section after the board has completely passed the trimming knife 21 is not limited and supported by the support wheel 222, further reducing the conveying resistance and improving the processing efficiency.

[0039] It should be noted that the use of pressure roller 112, support roller 222, and side support roller 231 to contact the plate is only a preferred example of this application. The structure of the pressure mechanism 11, support mechanism 22, and side support mechanism 23 in this application is not limited to the above example. They can also use pressure roller, support roller, side support roller, or pressure block, support block, or side support block with a smooth surface to directly contact the plate. This application does not make specific limitations in this regard.

[0040] It should also be noted that this application does not specifically limit the structure and material of the clamping wheel 112 or the support wheel 222. In one example, both the clamping wheel 112 and the support wheel 222 include a wheel body and an elastic rim covering the outside of the wheel body. Preferably, the elastic rim is made of rubber material. The rigid wheel body, made of metal or engineering plastic, provides sufficient clamping and supporting force, and the elastic rim cushions the material to prevent damage to the surface of the sheet metal during clamping. Of course, this is only a preferred example of this application, and other different structural forms of the support wheel 222 and the clamping wheel 112 can also be used.

[0041] Furthermore, referring to Figure 1As shown, the clamping mechanism 11 also includes a first connecting frame, which is the same length as the conveying mechanism 4 along the conveying direction. Multiple clamping wheels 112 are mounted on the first connecting frame. The support mechanism 22 also includes a second connecting frame, which has one or more sets corresponding to the number of support wheels 222. Each set of support wheels 222 is mounted on its corresponding second connecting frame. This allows for flexible adjustment of the arrangement of the clamping wheels 112 on the first connecting frame and the arrangement of the support wheels 222 on the second connecting frame according to actual needs. This allows for adaptation to / avoidance of protruding structures on irregularly shaped plates, and also facilitates the maintenance and replacement of the clamping wheels 112 and support wheels 222.

[0042] Furthermore, referring to Figure 2 As shown, the side support mechanism 23 also includes multiple side support rods 232, each corresponding to a side support wheel 231. The side support wheel 231 is located at the end of the side support rod 232 facing the conveying mechanism 4. The side support mechanism 23 also includes a side support drive assembly connected to the side support rods 232. The side support drive assembly drives the multiple side support rods 232 to extend and retract synchronously or asynchronously. Using the above structure, synchronous extension and retraction of the side support rods 232 driven by the side support drive assembly is suitable for processing plates with regular edge structures, while asynchronous extension and retraction of the side support rods 232 driven by the side support drive assembly is suitable for processing plates with irregular edge structures, further improving the versatility of the edge banding machine in this application. In one example, the side support drive assembly includes multiple drive cylinders, each correspondingly connected to a side support rod 232. The drive cylinders drive the side support rods 232 connected to them, causing the side support wheels 231 on the side support rods 232 to extend and retract. The drive cylinder can directly output linear motion, and can respond promptly to changes in the edge shape of the sheet metal with irregular edge structures. The drive side support mechanism 23 provides stable and effective side support for the sheet metal. Here, the drive cylinder is preferably an electric cylinder, which has a faster response speed and is easier to control precisely compared to hydraulic cylinders and pneumatic cylinders.

[0043] Of course, the structure of the side support drive assembly in this application is not limited to the above example. It can also adopt a combination of motor, gear and rack or other different drive mechanisms. This application does not make any specific limitations on this.

[0044] Furthermore, referring to Figure 1As shown, the edge banding machine in this application also includes a side curtain 31. One or more side curtains 31 are provided corresponding to the trimming blade 21. The height of the lower free end of the side curtain 31 in the vertical direction is not higher than the height of the upper surface of the board, and it is positioned between the corresponding trimming blade 21 and the pressing roller 112 in a direction perpendicular to the conveying direction of the conveying mechanism 4. In the above solution, by providing the side curtain 31, excess edge banding strip residue, solidified adhesive residue, etc., cut by the trimming blade 21 during the trimming process can be prevented from falling into the space between the pressing roller 112 and the board, causing damage to the board surface. The fact that the lower free end of the side curtain 31 is not higher than the upper surface of the board ensures close contact between the side curtain 31 and the board surface, preventing residual edge banding strip residue, sawdust, solidified adhesive residue, etc., from leaking through the gap between the side curtain 31 and the board surface. Preferably, the lower free end of the side curtain 31 has a flexible structure or is made of a flexible component. In one example, the side curtain 31 includes a plastic frame 311 and a fabric piece 312 disposed below the plastic frame. This arrangement ensures the structural stability of the side curtain 31 and also prevents the side curtain 31 from being entirely made of a rigid structure and scratching the surface of the board.

[0045] It should be noted that this application does not specifically limit the structure and arrangement of the side curtain 31. In one example, the side wall of the upper pressure beam 1 is provided with a slot 32, and both ends of the side curtain 31 are fixed in the slot 32. Of course, the arrangement of the side curtain 31 in this application is not limited to the above example, and other arrangements can also be used.

[0046] The technical solutions protected by this utility model are not limited to the above embodiments. It should be noted that any combination of the technical solutions of any embodiment with one or more other embodiments is within the protection scope of this utility model. Although this utility model has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model are within the scope of protection claimed by this utility model.
