Description

Technical fields:

[0001] This utility model relates to the technical field of pre-milling devices for edge banding machines, and in particular to a servo pre-milling device for edge banding machines. Background technology:

[0002] An edge banding machine is a type of woodworking machinery, belonging to the category of solid wood machinery. As the name suggests, an edge banding machine is used for edge banding. It includes a pre-milling device.

[0003] Most existing pre-milling devices for edge banding machines are like the one disclosed in Chinese Utility Model Patent Application No. CN202023000863.9, which includes a pre-milling base, a front pre-milling module, and a rear pre-milling module. The front and rear pre-milling modules each include a milling cutter slide connected to the pre-milling base in the front-to-back direction, a milling cutter assembly disposed on the milling cutter slide, a cylinder-driven power mechanism for driving the milling cutter slide to slide back and forth, and a tool adjusting assembly for adjusting the front and back position of the milling cutter slide. The cylinder-driven power mechanism is used to control the advance and retraction of the milling cutter assembly so that the milling cutter assembly can retract after milling and prevent interference. The tool adjusting assembly includes an adjusting screw and a stroke digital display, which means that the adjusting screw needs to be manually turned to adjust the tool. Since the milling cutter will wear out after a period of use and needs to be replaced, the replaced milling cutter needs to be re-set to ensure the milling amount of the wood board. The manual adjustment after each tool replacement is not only cumbersome but also inefficient. Utility Model Content:

[0004] The purpose of this invention is to provide a servo pre-milling device for edge banding machines to address the shortcomings of existing technologies. This device can replace the previous method of manually adjusting the screw for automatic tool adjustment, which not only reduces the workload of operators but also improves tool adjustment efficiency and is better suited for edge banding machines.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a servo pre-milling device for an edge banding machine, comprising a pre-milling base, a front pre-milling module, and a rear pre-milling module. The front pre-milling module and the rear pre-milling module each include a milling cutter slide connected to the pre-milling base in the front-rear direction, a milling cutter assembly disposed on the milling cutter slide, a lead screw nut disposed on the milling cutter base, a transmission lead screw threadedly connected to the lead screw nut, and a servo motor for driving the transmission lead screw to rotate. The servo motor is disposed on the milling cutter slide, and the output end of the servo motor drives the transmission lead screw.

[0006] A further improvement to the above solution is that the present invention also includes a thickness detection device for detecting the thickness of the sheet metal.

[0007] A further improvement to the above solution is that the thickness detection device includes a detection base, a detection slide connected to the detection base in the front-to-back direction, a detection roller connected to the detection slide in the vertical direction, a detection block set on the detection slide, a detection frame set on the detection base, a self-resetting linear displacement sensor set on the detection frame, and a reset compression spring clamped between the detection block and the detection frame. The self-resetting linear displacement sensor includes a detection probe, which abuts against the detection block.

[0008] A further improvement to the above scheme is that the detection frame has a first through hole, the detection block has a second through hole, and the detection frame has an adjusting bolt. The threaded end of the adjusting bolt passes through the first through hole and the second through hole in sequence and is threadedly connected to an adjusting nut.

[0009] A further improvement to the above scheme is that the reset compression spring is sleeved on the adjusting bolt.

[0010] A further improvement to the above solution is that the detection base is provided with a detection slide rail, a detection slider is slidably connected on the detection slide rail, and the detection slider is connected to the detection slide block.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a servo pre-milling device for an edge banding machine, including a pre-milling base, a front pre-milling module, and a rear pre-milling module. The front pre-milling module and the rear pre-milling module each include a milling cutter slide connected to the pre-milling base in the front-rear direction, a milling cutter assembly set on the milling cutter slide, a lead screw nut set on the milling cutter base, a transmission lead screw threadedly connected to the lead screw nut, and a servo motor for driving the transmission lead screw to rotate. The servo motor is set on the milling cutter slide, and the output end of the servo motor drives the transmission lead screw.

[0012] Compared to existing pre-milling devices that require manual adjustment of the lead screw for tool adjustment, this invention uses a servo motor to drive the lead screw in both forward and reverse rotation, which, in conjunction with the lead screw nut, causes the pre-milling slide to slide back and forth. This allows for adjustment of the relative position between the milling cutter assembly and the sheet metal, thus replacing the previous method of manually adjusting the lead screw for automatic tool adjustment. This not only reduces the workload of operators but also improves tool adjustment efficiency, making it better suited for edge banding machines. Furthermore, compared to the previous method that required separate cylinder-driven power mechanisms and tool adjustment components, this invention uses a servo motor to drive the lead screw in both forward and reverse rotation, which, in conjunction with the lead screw nut, causes the pre-milling slide to slide back and forth, thus moving the milling cutter assembly back and forth. This not only replaces the cylinder-driven power mechanism for tool advance and retraction but also replaces the tool adjustment component for tool adjustment, making it more practical.

[0018] The present invention will be further described below with reference to the accompanying drawings, such as... Figure 1-4 As shown, this utility model includes a pre-milling base 2, a front pre-milling module 3, and a rear pre-milling module 4. The front pre-milling module 3 and the rear pre-milling module 4 each include a milling cutter slide 31 slidably connected to the pre-milling base 2 in the front-to-back direction, a milling cutter assembly 32 disposed on the milling cutter slide 31, a lead screw nut 33 disposed on the milling cutter base, a transmission lead screw 34 threadedly connected to the lead screw nut 33, and a servo motor 35 for driving the transmission lead screw 34 to rotate. The servo motor 35 is disposed on the milling cutter slide 31, and its output end drives the transmission lead screw 34. Compared to existing pre-milling devices that require manual adjustment of the lead screw for tool adjustment, this utility model uses the servo motor 35 to drive the transmission lead screw 34 in both forward and reverse directions, and through its interaction with the lead screw nut 33... This invention enables the pre-milling slide to slide back and forth, thus adjusting the relative position between the milling cutter assembly 32 and the sheet metal. This replaces the previous method of manually turning the adjusting screw for automatic tool adjustment, reducing the workload of operators and improving tool adjustment efficiency, making it more suitable for edge banding machines. Furthermore, compared to the previous method requiring separate cylinder-driven power mechanisms and tool adjustment components, this invention uses a servo motor 35 to drive the transmission screw 34 in both forward and reverse directions, which, in conjunction with the screw nut 33, drives the pre-milling slide to slide back and forth, thereby moving the milling cutter assembly 32 back and forth. This not only replaces the cylinder-driven power mechanism for tool advance and retraction but also replaces the tool adjustment component for tool adjustment, making it more practical.

[0019] This invention also includes a thickness detection device 1 for detecting the thickness of the sheet metal. The thickness detection device 1 enables automatic detection of the sheet metal thickness, further improving the automation level of automatic tool adjustment. This invention also includes a controller 5. After tool change, the sheet metal is milled by the front pre-milling module 3 and the rear pre-milling module 4 respectively. Then, the thickness of the sheet metal is detected by the thickness detection device 1. The controller 5 adjusts the milling cutter assembly 32 of the front pre-milling module 3 and / or the milling cutter assembly 32 of the rear pre-milling module 4 according to the detection result of the thickness detection device 1. This ensures that the two milling cutter assemblies 32 of the front pre-milling module 3 and the rear pre-milling module 4 are located at preset reference positions and on the same plane, ensuring the flatness of the sheet metal after milling and achieving a higher overall level of automation.

[0020] Thickness detection device 1 includes a detection base 11, a detection slide 12 slidably connected to the detection base 11 in the front-to-back direction, a detection roller 13 rotatably connected to the detection slide 12 in the vertical direction, a detection block 14 disposed on the detection slide 12, a detection frame 15 disposed on the detection base 11, a self-resetting linear displacement sensor 16 disposed on the detection frame 15, and a reset compression spring 17 sandwiched between the detection block 14 and the detection frame 15. The self-resetting linear displacement sensor 16 includes a detection probe 161, which abuts against the detection block 14. When the movable plate to be detected moves to the position of the detection roller 13, the detection roller 13 rolls onto the movable plate to be detected, and the detection roller 13 is correspondingly pushed backward by the movable plate to be detected. As the detection roller 13 is pushed backward, the detection roller... The wheel 13 drives the detection slide 12 to slide backward, causing the detection block 14 located on the detection slide 12 to push the detection probe 161 of the self-resetting linear displacement sensor 16 backward. By combining with the reset compression spring 17, the detection roller 13 will move back and forth according to the different thicknesses at various positions on the moving plate to be tested, and push the detection probe 161 of the self-resetting linear displacement sensor 16 to different degrees. Thus, the different thicknesses at various positions on the moving plate to be tested can be automatically detected according to the displacement of the detection probe 161 of the self-resetting linear displacement sensor 16. The thickness detection device 1 of this utility model can perform automated thickness detection on moving plates, which can not only reduce the workload of operators, but also improve the thickness detection efficiency and improve the overall plate processing efficiency.

[0021] In addition, compared with directly detecting the thickness of a moving sheet material through an infrared photoelectric sensor, which is easily affected by surface reflection, pores, dust, color, etc., the thickness detection device 1 of this utility model provides more accurate and stable detection results.

[0022] The detection frame 15 has a first through hole 151, and the detection block 14 has a second through hole 141. The detection frame 15 is equipped with an adjusting bolt 18. The threaded end of the adjusting bolt 18 passes through the first through hole 151 and the second through hole 141 in sequence and is threadedly connected to an adjusting nut 19. By adjusting the position of the adjusting nut 19 locked on the adjusting bolt 18, the position of the detection block 14 relative to the detection probe 161 of the self-resetting linear displacement sensor 16 can be adjusted accordingly, so that the position of the detection block 14 relative to the detection probe 161 of the self-resetting linear displacement sensor 16 can be adjusted according to the actual situation.

[0023] The reset compression spring 17 is sleeved on the adjusting bolt 18. When the moving plate to be tested moves to the position of the detection roller 13, the detection roller 13 rolls on the moving plate to be tested. The detection roller 13 is correspondingly pushed backward by the moving plate to be tested. As the detection roller 13 is pushed backward, the detection roller 13 drives the detection slide 12 to slide backward and causes the detection block 14 located on the detection slide 12 to push the detection probe 161 of the self-resetting linear displacement sensor 16 backward. When the thickness of the moving plate to be tested decreases or it passes through the position of the detection roller 13, the reset compression spring 17 pushes the detection block 14 forward to slide and reset, and drives the detection roller 13 to move forward and reset.

[0024] The detection base 11 is provided with a detection slide rail 20, and a detection slider 21 is slidably connected on the detection slide rail 20. The detection slider 21 is connected to the detection slide block 12. Through the cooperation of the detection slide rail 20 and the detection slider 21, the detection slide block 12 can slide more smoothly on the detection base 11, thereby better realizing the thickness detection of the moving plate.

[0025] Working principle:

[0026] The servo motor 35 drives the transmission screw 34 to rotate, causing the milling cutter slide 31 to slide forward and approach the plate to be milled, thus completing the feed. The milling cutter assembly 32 pre-mills the plate to be milled. After the pre-milling is completed, the servo motor 35 drives the transmission screw 34 to rotate, causing the milling cutter slide 31 to slide backward and away from the plate to be milled, thus completing the retraction. When tool adjustment is required, the servo motor 35 drives the transmission screw 34 to rotate, causing the milling cutter slide 31 to move forward or backward according to the specific situation, so that the milling cutter assembly 32 is at the preset reference position, thus completing the tool adjustment. This utility model can replace the previous method of manually turning the adjustment screw for automatic tool adjustment, which can not only reduce the workload of operators, but also improve the tool adjustment efficiency, and is better suited for edge banding machines.

[0027] Of course, the above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
