Description

Technical Field

[0001] This application belongs to the field of trimming technology, and more specifically, relates to a trimming machine. Background Technology

[0002] With the improvement of consumers' aesthetic standards and the pursuit of personalized home environments, aesthetics and personalized design have become important manifestations of the core competitiveness of furniture products. To achieve a unique design style and exquisite appearance, the edges of the various panels that make up the furniture are usually covered with edge banding tape. Edge banding tape not only covers burrs and imperfections on the edges of the panels, improving their overall aesthetics, but also effectively prevents the edges from getting damp and cracking, extending the lifespan of the furniture. After the edge banding tape is applied, excess tape will remain at the outline of the panel edge, requiring careful trimming to ensure that the edge banding tape is flush with the edge of the panel.

[0003] In traditional techniques, the edge trimming process after the board is sealed relies heavily on manual labor: the operator first uses a utility knife or other hand tools to cut off the excess edge banding, and then sands it smooth. The trimming effect of manual trimming is highly correlated with the operator's experience and skill level, resulting in poor consistency and low efficiency, making it difficult to meet the stable quality and efficiency requirements of mass production. Summary of the Invention

[0004] The purpose of this application is to provide an edge trimming machine to solve the technical problems of poor edge trimming consistency and low edge trimming efficiency in the prior art.

[0025] Please refer to the following: Figures 1 to 8 The edge trimming machine 100 provided in the embodiments of this application will now be described. The edge trimming machine 100 is used to trim the edges of a workpiece 200 with edge banding tape. For example, the workpiece 200 is a board for furniture. After the edge banding tape is used to seal the edges of the furniture board, there is excess edge banding tape on the outline edge of the board. The edge trimming machine 100 is used to cut off the excess edge banding tape on the edge banding outline of the board.

[0026] Please refer to the following: Figure 1 and Figure 2The trimming machine 100 includes a worktable 10, a first displacement device 20, a second displacement device 30, a trimming device 40, and a positioning device 12. The worktable 10 is provided with a table surface 111 for placing the workpiece 200. The first displacement device 20 is disposed on the worktable 10, the second displacement device 30 is disposed on the first displacement device 20, and the trimming device 40 is disposed on the second displacement device 30. The first displacement device 20 is used to drive the second displacement device 30 and the trimming device 40 to reciprocate in the horizontal direction. The second displacement device 30 is used to drive the trimming device 40 to reciprocate in the vertical direction. Under the drive of the first displacement device 20 and the second displacement device 30, the trimming device 40 can move along the edge contour of the workpiece 200 to perform contour trimming on the workpiece 200. That is, under the drive of the first displacement device 20 and the second displacement device 30, the trimming device 40 can move in accordance with the edge contour of the workpiece to perform contour cutting trimming on the excess edge banding. The positioning device 12 is provided on the worktable 10 and is used to position the workpiece 200 on the table surface 111.

[0027] For example, the table surface 111 is the upper surface of the workbench 10. In use, the workpiece 200 is fixed on the table surface 111 of the workbench 10, and the positioning device 12 presses the workpiece 200 on the table surface 111 to position the workpiece 200. Then, the trimming device 40 is activated, and with the cooperation of the first displacement device 20 and the second displacement device 30, the trimming device 40 is driven to perform horizontal and vertical contouring movements along the edge sealing contour of the workpiece 200 to trim the excess part of the edge sealing strip of the workpiece 200.

[0028] Compared with the prior art, the trimming machine 100 provided in this application uses a first displacement device 20 to drive a second displacement device 30 and a trimming device 40 to move horizontally and reciprocally. The second displacement device 30 drives the trimming device 40 to move vertically and reciprocally. This allows the trimming device 40 to move along the edge contour of the workpiece 200 under the drive of the first displacement device 20 and the second displacement device 30 for contour trimming. At the same time, the positioning device 12 can position the workpiece 200 on the table 111, reducing the uncertainty of manual operation, making the trimming process more stable, effectively improving the consistency of the trimming effect and the trimming efficiency, and meeting the stable requirements of quality and efficiency for mass production.

[0029] Specifically, the first displacement device 20 and the second displacement device 30 drive the trimming device 40 to move precisely in the horizontal and vertical directions, enabling the trimming device 40 to accurately conform to the edge contour of the workpiece 200 and perform contour trimming on the workpiece 200. This replaces the traditional manual operation that relies on human experience and feel, thereby significantly improving the consistency of the trimming path and processing accuracy, and ensuring a uniform and stable trimming effect. The positioning device 12 presses the workpiece 200 onto the table 111, making the workpiece 200 accurately and stably fixed on the table 111, effectively avoiding trimming deviations caused by the movement of the workpiece 200. That is, compared with the problem of cutting deviations caused by the easy shaking of the workpiece 200 during manual trimming, the stability of trimming is significantly improved. Understandably, using the trimming machine 100 of this application for trimming significantly improves processing efficiency and product qualification rate, reduces the dependence on the operator's technical skills, and can stably meet the standardized requirements for quality and efficiency in mass production.

[0030] Furthermore, the trimming machine 100 provided in this application can effectively trim adjacent edges and irregular joints of the workpiece 200 to precisely cut excess edge banding at the sides and end joints of the workpiece 200. This allows for the completion of trimming at the sides and end joints of the workpiece 200 in one operation, thereby improving the consistency of trimming results and increasing trimming efficiency. The shape of the aforementioned end joints can be, but is not limited to, beveled, arc-shaped, C-shaped, or J-shaped.

[0031] In one embodiment of this application, please refer to Figure 3 and Figure 4 The first displacement device 20 includes a horizontal guide assembly 21, a transition frame 22, and abutment 23. The horizontal guide assembly 21 is disposed on the side end of the worktable 10, the transition frame 22 is connected to the horizontal guide assembly 21, and the abutment 23 is disposed on the transition frame 22 for the workpiece 200 to abut against. By using the abutment 23 fixed on the transition frame 22 to position the workpiece 200 against the transition frame 22, the trimming path of the trimming device 40 can be indirectly constrained, which is beneficial to improving the positioning accuracy of the workpiece 200 and the trimming consistency of the end edge, thereby increasing the trimming accuracy of the workpiece 200.

[0032] Optionally, the horizontal guide assembly 21 includes a horizontal guide rail 211, a horizontal slider 212, and a blocking block 213. The horizontal guide rail 211 is disposed on the side of the worktable 10, and the length direction of the horizontal guide rail 211 is parallel to the horizontal direction. The horizontal slider 212 is slidably disposed on the horizontal guide rail 211 and connected to the adapter frame 22. There are two blocking blocks 213, which are respectively disposed at both ends of the horizontal guide rail 211 along the sliding direction to prevent the horizontal slider 212 from disengaging from the horizontal guide rail 211, thereby ensuring the stability of the horizontal guide assembly 21 in use.

[0033] Optionally, the adapter frame 22 includes a base plate 221 and a drag arm 222. The base plate 221 is connected to the horizontal guide component 21 and the second displacement device 30. The drag arm 222 is connected to the abutment member 23. There are two drag arms 222, which are respectively arranged on both sides of the base plate 221 along the moving direction of the horizontal guide component 21. Correspondingly, there are also two abutment members 23, which are respectively arranged on each horizontal guide component 21. A clearance groove 223 corresponding to the position of the trimming device 40 is formed between the two drag arms 222.

[0034] In one embodiment of this application, please refer to Figure 3 and Figure 4 The abutment 23 includes a wheel box 231, a guide wheel 232 and a fixing member 233. The wheel box 231 is disposed on the adapter frame 22. The guide wheel 232 is rotatably disposed in the wheel box 231. The side of the guide wheel 232 facing the worktable 10 is exposed in the wheel box 231 so that it can roll and contact the edge of the workpiece 200 on the table surface 111. During the trimming process, when the workpiece 200 contacts the abutment 23, the guide wheel 232 can roll, which helps to reduce the friction between the abutment 23 and the edge of the workpiece 200. This effectively guides the workpiece 200, ensuring its accurate position during the trimming process, allowing the trimming device 40 to move more precisely along the edge contour of the workpiece 200 for contour trimming and improving trimming accuracy. It also avoids damage to the edge of the workpiece 200 due to excessive friction, ensuring the integrity and quality of the workpiece 200. At the same time, it helps to improve the smoothness of the trimming process, further improves trimming efficiency, and meets the stable requirements of quality and efficiency for mass production.

[0035] Optionally, the number of abutment members 23 is at least two, and the at least two abutment members 23 are arranged sequentially at intervals along the horizontal direction. Each abutment member includes multiple guide wheels 232, and the multiple guide wheels 232 are arranged sequentially along the horizontal direction.

[0036] Optionally, the wheel box 231 is provided with an adjustment groove 234, and the fixing member 233 passes through any position of the adjustment groove 234 and is connected to the adapter frame 22 to connect the wheel box 231 to the adapter frame 22, and to allow the wheel box 231 to move closer to or further away from the worktable 10 along the extension direction of the adjustment groove 234. The adjustment groove 234 is a strip-shaped groove, and the length direction of the adjustment groove 234 is perpendicular to the moving direction of the adapter frame 22. The fixing member 233 is a screw. By adjusting the position of the fixing member 233 in the adjustment groove 234, the distance between the abutment 23 and the worktable 10 can be adjusted, thereby accommodating workpieces 200 with beveled sides, and achieving the purpose of expanding the processing applicability range of the trimming device. For example, please refer to... Figure 1For workpiece 200 whose bottom edge and top edge are far apart, the distance between the abutment 23 and the worktable 10 can be adjusted so that when the side of workpiece 200 to be trimmed corresponds to the position of trimming device 40, the other side is in reliable contact with abutment 23, so that trimming device 40 can perform trimming processing.

[0037] In another embodiment of this application, the first displacement device 20 further includes a horizontal drive source, which is disposed on the worktable 10 and connected to the adapter frame 22. The horizontal drive source is used to drive the adapter frame 22 to move horizontally, thereby driving the second displacement device 30, the trimming device 40, and the abutment member 23 to move automatically in the horizontal direction. This improves the degree of automation and thus enhances the trimming quality and efficiency. Optionally, the horizontal drive source may be, but is not limited to, a motor.

[0038] In one embodiment of this application, in order to reduce the labor intensity of operators and increase trimming efficiency, please refer to... Figure 5 and Figure 6 The second displacement device 30 includes a vertical guide assembly 31, a mounting frame 32, and an elastic assembly 33. The vertical guide assembly 31 is connected to the first displacement device 20 and the mounting frame 32, and is used to guide the mounting frame 32 to move back and forth in the vertical direction relative to the first displacement device 20. The elastic assembly 33 is connected to the first displacement device 20 and the mounting frame 32, and is used to provide elastic support for the mounting frame 32 to slide along the vertical guide assembly 31. By providing elastic support for the mounting frame 32 through the elastic assembly 33, the labor intensity can be effectively reduced, the operation time can be extended, and the trimming efficiency can be increased.

[0039] Specifically, the vertical guide component 31 guides the mounting frame 32 to move precisely back and forth in the vertical direction, ensuring that the trimming device 40 can accurately track the vertical changes of the edge contour of the workpiece 200, thereby achieving high-precision vertical positioning during the contour trimming process. Simultaneously, the elastic component 33 provides elastic support to the mounting frame 32, effectively offsetting part of the trimming device 40's own weight and movement resistance, making vertical movement more effortless and stable, reducing the operator's physical load and the volatility of manual control. The synergistic effect of these two components not only improves the stability and response speed of the trimming device 40 in the vertical direction but also further ensures the continuity and consistency of the overall trimming path, thereby significantly enhancing the uniformity of the trimming effect and processing efficiency, and reducing the impact of manual intervention on accuracy.

[0040] Please refer to Figure 5 The vertical guide assembly 31 includes a vertical guide rail 311 and a vertical slider 312. The vertical guide rail 311 is disposed on the first displacement device 20, and the vertical slider 312 slides along the vertical guide rail 311 and is connected to the mounting bracket 32.

[0041] In one embodiment of this application, to improve work efficiency while increasing trimming accuracy, please refer to... Figure 5 The elastic component 33 includes a first connector 331, a second connector 332, and an elastic element 333. The first connector 331 is mounted on the adapter frame 22 of the first displacement device 20, and the second connector 332 is mounted on the mounting frame 32. The elastic element 333 connects the first connector 331 and the second connector 332. Both the first connector 331 and the second connector 332 are screws, and the elastic element 333 is a tension spring. A limiting block is provided between the two first connectors 331. There are two elastic components 33, which are respectively located on both sides of the vertical guide component 31. The tension spring provides an upward elastic force, which can effectively balance the weight of the trimming device 40, reduce operator fatigue, and improve work efficiency. At the same time, the two symmetrically arranged elastic components 33 can effectively provide uniform support for the sliding of the mounting frame 32, prevent the mounting frame 32 from tilting, and improve trimming accuracy.

[0042] In one embodiment of this application, to improve the accuracy of the trimming operation while ensuring the protection of the operator, please refer to... Figure 5 and Figure 6 The second displacement device 30 also includes an observation window 34, which is mounted on the mounting bracket 32 ​​and located on the side of the trimming device 40 facing away from the table surface 111. Exemplarily, the observation window 34 is located directly above the trimming blade of the trimming device 40. The observation window 34 can block debris generated above the trimming blade, preventing debris from splashing into the operator's eyes. During use, the operator can clearly observe the contact between the trimming blade (not shown) and the workpiece 200 through the observation window 34, and adjust the trimming path in a timely manner, thereby effectively reducing misoperation and improving the accuracy of the trimming operation. Specifically, the observation window 34 includes an adjustment frame 341, a frame 342, and a viewing plate 343. The adjustment frame 341 is connected to the mounting frame 32, the frame 342 is rotatably connected to the adjustment frame 341, and the viewing plate 343 is disposed on the frame 342. When picking up or placing the workpiece 200, the frame 342 can be rotated to fit against the mounting frame 32, thereby effectively preventing the frame 342 from obstructing the workpiece 200. During the trimming process, the frame 342 is rotated to align with the position of the trimming blade of the trimming device 40, and the viewing plate 343 prevents dust and chips, maintaining a clear field of vision, thereby improving the protection of the operator.

[0043] In one embodiment of this application, to improve the ease of maintenance and replacement of the trimming device 40 and reduce the operating cost of the trimming device 40, please refer to... Figure 5 and Figure 6The mounting bracket 32 ​​includes a mounting plate 321 and a clamping member 322. The mounting plate 321 is connected to the vertical guide assembly 31. Specifically, the mounting plate 321 is connected to the vertical slider 312 of the vertical guide assembly 31. The clamping member 322 is connected to the mounting plate 321 and is provided with a mounting hole 325 and a shrinkage groove 326 communicating with the mounting hole 325. The trimming device 40 is detachably disposed in the mounting hole 325. The clamping component 322 includes a fixing part 323 and a clamping part 324. The fixing part 323 is connected to the mounting plate 321 by bolts. There are two clamping parts 324, which are respectively connected to both ends of the fixing part 323. The ends of the two clamping parts 324 away from the fixing part 323 form a shrinkage groove 326. In use, one clamping part 324 can be threaded through a screw and connected to the other clamping part 324. The screw drives the two clamping parts 324 to move closer to each other, thereby clamping the trimming device 40. By clamping the trimming device 40 with the clamping component 322, the trimming device 40 can be quickly installed and disassembled, which facilitates the maintenance and replacement of the trimming device 40. This effectively increases the convenience of maintenance and replacement of the trimming device 40 and reduces the cost of using the trimming device 40.

[0044] In one embodiment of this application, please refer to Figure 5 and Figure 6 The mounting bracket 32 ​​also includes a control lever 327, which is connected to the mounting plate 321. The design of the control lever 327 provides convenience and stability for the operator's control, thereby reducing the difficulty of trimming, increasing the precision of trimming, and improving the quality of trimming.

[0045] In another embodiment of this application, the second displacement device 30 further includes a vertical drive source. The vertical drive source is disposed on the adapter frame 22 of the first displacement device 20 and connected to the mounting plate 321 of the mounting frame 32. The vertical drive source is used to drive the mounting frame 32 to move in the vertical direction. The mounting frame 32 drives the trimming device 40 to move automatically in the vertical direction, which is beneficial to improving the degree of automation and thus improving the trimming quality and efficiency. Optionally, the vertical drive source can be, but is not limited to, a motor.

[0046] In one embodiment of this application, please refer to Figure 1 and Figure 2 The positioning device 12 is located on the side of the workbench 10. The workpiece 200 is pressed and fixed on the workbench 10 by the positioning device 12 to prevent the workpiece 200 from shifting during the trimming process, thereby improving the stability and safety of the workpiece 200 during the trimming process.

[0047] Specifically, please refer to Figure 2 and Figure 7The positioning device 12 includes a clamping drive assembly 13 and a pressure plate 14. The clamping drive assembly 13 is disposed on the worktable 10 and connected to the pressure plate 14, and is used to drive the pressure plate 14 to perform lifting and lowering movements so that the pressure plate 14 can press the workpiece 200 on the table surface 111.

[0048] The clamping drive assembly 13 includes a drive source 131 and a control valve 132. The drive source 131 is mounted on the worktable 10 and connected to the pressure plate 14. The control valve 132 is used to control the drive source 131 to drive the pressure plate 14 closer to or further away from the worktable 10. The drive source 131 is a cylinder, and the control valve 132 is a manual cylinder valve. In this embodiment, the number of drive sources 131 can be one or more. When there are multiple drive sources 131, each drive source 131 is connected to the pressure plate 14 to increase the force when the pressure plate 14 is pressed down. In use, the cylinder action is controlled by the manual cylinder valve to achieve rapid lifting and lowering of the pressure plate 14, thereby improving the ease of operation.

[0049] In actual processing, there may be excess edge banding at both ends of workpiece 200. Therefore, after cutting off the excess edge banding at one end of workpiece 200, workpiece 200 needs to be lifted and its orientation changed so that the other end of workpiece 200 faces the trimming device 40. Only then can the trimming device 40 be controlled to cut off the excess edge banding at the other end of workpiece 200.

[0050] In one embodiment of this application, in order to improve the processing efficiency of workpiece 200 with excess edge banding at both ends, two positioning devices 12 are used. The two positioning devices 12 are respectively set at both ends of the worktable 10 in the horizontal direction. After the excess edge banding at one end of the workpiece 200 is cut off, the workpiece 200 is directly controlled to move on the table surface 111 of the worktable 10 to the other positioning device 12, so that the positioning device 12 can clamp the workpiece 200 to fix it, thereby effectively improving the trimming efficiency of workpiece 200 with excess edge banding at both ends. At the same time, for workpiece 200 whose trimming size is smaller than the table surface 111 of the worktable 10, both ends of the workpiece 200 can be clamped at once, thereby effectively improving the clamping firmness of the workpiece 200.

[0051] Optionally, please refer to Figure 7 and Figure 8The worktable 10 is provided with a clearance groove 112, which is used to accommodate the pressure plate 14. When the pressure plate 14 is accommodated in the clearance groove 112, the top surface of the pressure plate 14 is lower than the table surface 111 of the worktable 10. For workpieces 200 whose trimming size is larger than the table surface 111 of the worktable 10, by accommodating the pressure plate 14 in the clearance groove 112, the workpieces 200 on the table surface 111 of the worktable 10 can be effectively prevented from shifting, thereby effectively reducing the floor space occupied by the worktable 10. At the same time, it can realize the fixed processing of large-sized workpieces 200, thereby effectively improving the operational convenience of workpieces 200 in the processing process and the space utilization rate of the worktable 10.

[0052] Furthermore, to improve the fixing effect on workpiece 200, please refer to... Figure 7 The pressure plate 14 includes a pressure part 141 and a connecting part 142. There are multiple pressure parts 141, which are spaced apart. The connecting part 142 is connected to the drive source 131. The number of clearance grooves 112 is the same as the number of pressure parts 141, and they are spaced apart. The multiple spaced pressure parts 141 can clamp the workpiece 200 together with the table surface 111 between each pressure part 141, thereby reducing the suspended area of ​​the workpiece 200 at the clearance groove 112 and achieving the purpose of improving the fixing effect of the workpiece 200.

[0053] Please see Figure 7 and Figure 8 The workbench 10 is provided with a receiving slot 113, which is connected to the clearance slot 112 and is located on one side of the workbench 10. The drive source 131 is set in the receiving slot 113. The drive source 131 is hidden by the receiving slot 113, which helps to reduce the space occupied by the drive source 131, keep the appearance of the workbench 10 clean, and further improve the space utilization of the workbench 10.

[0054] Please see Figure 2 The trimming device 40 includes a body 41 and a trimming knife connected to the body 41. The body 41 is mounted on the second displacement device 30. The trimming knife is used to trim the workpiece 200 to cut off excess edge banding on the workpiece 200. That is, the trimming knife is the cutting execution component of the trimming device 40.

[0055] When using the trimming machine 100 provided in this application: the workpiece 200 is placed on the table surface 111 of the worktable 10, and one side of the workpiece 200 abuts against the guide wheel 232 of the abutment member 23. One end of the workpiece 200 is placed between the table surface 111 and the pressure plate 14 of the worktable 10. The pressure plate 14 is controlled to move closer to the table surface 111 of the worktable 10 using the drive source 131 to press the workpiece 200 firmly onto the table surface 111. The operator holds the control lever 327 on the mounting frame 32, adjusts the height of the trimming device 40 through the second displacement device 30, and uses the elastic support force of the elastic component 33 to drive the mounting frame 32 to slide up and down along the vertical guide rail 311, so that the cutting end of the trimming knife fits the contour of the workpiece 200. Then, the first displacement device 20 is pushed to move horizontally according to the workpiece 200. The vertical displacement of the profile of 0 is adjusted so that the trimming knife fits the profile of the workpiece 200 to achieve contour cutting. The excess edge banding at the side and end edge joint of the workpiece 200 is processed in one go. During the trimming process, the contact between the trimming knife and the workpiece 200 is monitored in real time through the observation window 34. The horizontal / vertical movement speed or direction is adjusted in time to avoid over-cutting or omission. After the trimming of one end of the workpiece 200 is completed, the control valve 132 is operated to release the pressure plate 14 at the corresponding end. The workpiece 200 is moved along the table 111 so that the other end to be trimmed is aligned with the trimming knife. At the same time, one side of the workpiece 200 is still against the abutment 23. The control valve 132 of the positioning device 12 at the other end is operated to press the workpiece 200 and then perform the trimming operation on the other end of the workpiece 200. The excess edge banding on the left and right sides of the workpiece 200 is trimmed.
