Description

Technical Field

[0001] This utility model belongs to the field of edge trimming machine technology, specifically relating to an edge trimming machine for high-density board processing. Background Technology

[0002] High-density fiberboard (HDF) is a type of board made from wood fibers or other plant fibers, pressed together with urea-formaldehyde resin or other synthetic resins under heat and pressure. It is widely used in furniture production and processing. In the processing of HDF, the edges of the board need to be trimmed. In the existing technology, the trimming machine used for HDF needs to be manually positioned repeatedly and can only trim one edge of the board at a time, resulting in low trimming efficiency for HDF. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a trimming machine for high-density fiberboard (HDF) processing. This device can quickly position the board to be trimmed and simultaneously grind and trim the four edges of the board, greatly improving the efficiency of board trimming.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a trimming machine for high-density fiberboard processing, comprising a machine base, a first electric telescopic rod installed on the inner side of the machine base, the piston rod end of the first electric telescopic rod being connected to a mounting frame, a lifting support seat fixedly installed on the inner side of the mounting frame, a rubber pad provided on the top of the lifting support seat, a negative pressure suction hole penetrating between the top and bottom of the lifting support seat and the rubber pad, the bottom of the negative pressure suction hole being connected to a negative pressure pipe, a negative pressure pump installed inside the machine base, the suction port of the negative pressure pump being connected to the end of the negative pressure pipe, a bracket installed on the top of the machine base, a top plate installed on one side of the bracket, a second electric telescopic rod installed at the bottom of the top plate, a mounting plate installed at the bottom of the second electric telescopic rod, a four-sided synchronous grinding device provided at the bottom of the mounting plate, and a positioning clamping mechanism provided on the top of the machine base.

[0005] The beneficial effects of this utility model are as follows: This device can quickly position the board to be trimmed and can simultaneously grind and trim the four edges of the board, which greatly improves the efficiency of board trimming.

[0006] To improve the efficiency of sanding and trimming:

[0007] As a further improvement to the above technical solution: the four-sided synchronous grinding device includes a first drive slide rail and a second drive slide rail connected by a connecting rod and installed at the bottom of the mounting plate. A lead screw is rotatably installed on the inner side of the first drive slide rail and the second drive slide rail, and a first slider is slidably provided thereon. A first adjusting slide rail is installed below the first slider of the first drive slide rail, and a second adjusting slide rail is installed below the first slider of the second drive slide rail. A first bidirectional lead screw is rotatably installed on the inner side of the first adjusting slide rail and the second adjusting slide rail, and a second slider is slidably provided thereon. An edge trimming device is installed at the bottom of the second slider.

[0008] The beneficial effects of this improvement are as follows: The operation of the first and second servo motors is controlled according to the dimensions of the board material. The first servo motor drives the lead screw, and the transmission between the lead screw and the first slider drives the first and second adjusting slide rails to adjust their positions. This moves each set of fixed frames to the trimming starting point close to each corresponding edge of the board material. The operation of the second servo motor drives the first bidirectional lead screw to rotate, causing the two sets of fixed frames located below the first adjusting slide rail to move closer together, and also causing the two sets of fixed frames located below the second adjusting slide rail to move closer together, so that the grinding and trimming roller contacts the four edges of the board material. Then, the trimming drive motor can be turned on to drive the grinding and trimming roller to rotate, grinding the four edges of the board material. The first servo motor drives the lead screw to move the first slider, causing the first and second adjusting slide rails, connected to the fixed frames, the trimming drive motor, and the grinding and trimming roller to move along the edge of the board material, achieving simultaneous grinding of all four edges and improving the efficiency of grinding and trimming.

[0009] To sand the four sides of the board:

[0010] As a further improvement to the above technical solution: the trimming device includes a fixed frame installed at the bottom of the second slider, and a trimming drive motor is installed on the inner side of the fixed frame. The output end of the trimming drive motor is connected to the grinding and trimming roller.

[0011] The beneficial effects of this improvement are: turning on the trimming drive motor drives the grinding and trimming roller to rotate, which is used to grind the four sides of the board.

[0012] To move each set of fixing frames to the starting point of the trimming process for each edge of the corresponding sheet material:

[0013] As a further improvement to the above technical solution: a first servo motor is provided at one end of both the first drive slide rail and the second drive slide rail, the output end of the first servo motor is connected to the lead screw, and the lead screw and the first slider are threaded together.

[0014] The beneficial effects of this improvement are as follows: the first servo motor drives the lead screw to run, and the transmission between the lead screw and the first slider drives the first and second adjusting slide rails to adjust their positions, thereby moving each set of fixing frames to the trimming start end close to each edge of the corresponding plate.

[0015] To ensure the sanding and trimming roller contacts all four edges of the sheet material:

[0016] As a further improvement to the above technical solution: a second servo motor is installed at one end of the first adjusting slide rail and the second adjusting slide rail, the output end of the second servo motor is connected to the first bidirectional lead screw, and the first bidirectional lead screw and the second slider are threaded together.

[0017] The beneficial effects of this improvement are as follows: by operating the second servo motor, the first bidirectional lead screw is driven to rotate, thereby causing the two sets of fixed frames located below the first adjusting slide rail to move closer to each other, and causing the two sets of fixed frames located below the second adjusting slide rail to move closer to each other, so that the grinding and trimming roller contacts the four edges of the board.

[0018] To clamp and position the sheet material:

[0019] As a further improvement to the above technical solution: the positioning and clamping mechanism includes a clamping adjustment rail set on the top of the machine table, a second bidirectional lead screw rotatably mounted on the inner side of the clamping adjustment rail and a third slider slidably mounted thereon, a clamping plate mounting bracket mounted on the top of the third slider, a third electric telescopic rod mounted on the side of the clamping plate mounting bracket, the piston rod end of the third electric telescopic rod being connected to the positioning clamping plate, the third slider and the second bidirectional lead screw being threadedly connected, and one end of the second bidirectional lead screw passing through the side of the machine table and being connected to a handwheel.

[0020] The beneficial effects of this improvement are as follows: By rotating the second bidirectional lead screw through the handwheel, the transmission between the second bidirectional lead screw and the third slider drives the left and right sets of third sliders to move closer to each other. The movement of the third slider drives the clamping plate mounting bracket, the third electric telescopic rod, and the positioning clamping plate to move. When the positioning clamping plate moves close to the four corners of the plate, the piston rod of the third electric telescopic rod is extended, driving the positioning clamping plate toward the plate. Through the push of the positioning clamping plate, the plate is moved accordingly. Personnel can assist in adjusting the position of the plate until the positioning clamping plate clamps and positions the plate at the four corners.

[0021] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0033] like Figure 1-9As shown, a high-density fiberboard (HDF) trimming machine includes a machine base 1. A first electric telescopic rod 2 is installed on the inner side of the machine base 1. The piston rod end of the first electric telescopic rod 2 is connected to a mounting frame 3. A lifting support seat 4 is fixedly installed on the inner side of the mounting frame 3. A rubber pad 5 is provided on the top of the lifting support seat 4. A negative pressure suction hole 6 is provided through the top and bottom of the lifting support seat 4 and the rubber pad 5. The bottom of the negative pressure suction hole 6 is connected to a negative pressure pipe 7. A negative pressure pump 8 is installed inside the machine base 1. The suction port of the negative pressure pump 8 is connected to the end of the negative pressure pipe 7. A bracket 9 is installed on the top of the machine base 1. A top plate 10 is installed on one side of the bracket 9. A second electric telescopic rod 11 is installed on the bottom of the top plate 10. A mounting plate 12 is installed on the bottom of the second electric telescopic rod 11. A four-sided synchronous grinding device is provided on the bottom of the mounting plate 12. A positioning and clamping mechanism is provided on the top of the machine base 1.

[0034] This device can quickly position the board material to be trimmed and simultaneously grind and trim the four edges of the board, greatly improving the efficiency of board trimming.

[0035] The four-sided synchronous grinding device includes a first drive slide rail 13 and a second drive slide rail 14 connected by a connecting rod and installed at the bottom of the mounting plate 12. A lead screw 15 is rotatably installed on the inner side of the first drive slide rail 13 and the second drive slide rail 14, and a first slider 16 is slidably provided thereon. A first adjusting slide rail 18 is installed below the first slider 16 of the first drive slide rail 13, and a second adjusting slide rail 19 is installed below the first slider 16 of the second drive slide rail 14. A first bidirectional lead screw 20 is rotatably installed on the inner side of the first adjusting slide rail 18 and the second adjusting slide rail 19, and a second slider 21 is slidably provided thereon. A trimming device is installed at the bottom of the second slider 21.

[0036] The operation of the first servo motor 17 and the second servo motor 22 is controlled according to the size of the board material. The first servo motor 17 drives the lead screw 15, and the transmission between the lead screw 15 and the first slider 16 drives the first adjusting slide rail 18 and the second adjusting slide rail 19 to adjust their positions. This causes each set of fixing brackets 23 to move closer to the trimming start end of each corresponding edge of the board material. The operation of the second servo motor 22 drives the first bidirectional lead screw 20 to rotate, causing the two sets of fixing brackets 23 located below the first adjusting slide rail 18 to move closer to each other, and thus... The two sets of fixed frames 23 located below the second adjusting slide rail 19 approach each other, so that the grinding and trimming roller 25 contacts the four edges of the board. Then, the trimming drive motor 24 can be turned on to drive the grinding and trimming roller 25 to rotate and grind the four edges of the board. The first servo motor 17 drives the lead screw 15 to move the first slider 16, which in turn drives the first adjusting slide rail 18, the second adjusting slide rail 19, the fixed frame 23, the trimming drive motor 24, and the grinding and trimming roller 25 to move along the edge of the board, so as to achieve simultaneous grinding of the four edges and improve the efficiency of grinding and trimming.

[0037] The trimming device includes a fixed frame 23 installed at the bottom of the second slider 21. A trimming drive motor 24 is installed on the inner side of the fixed frame 23. The output end of the trimming drive motor 24 is connected to the grinding and trimming roller 25.

[0038] Turn on the trimming drive motor 24 to drive the grinding and trimming roller 25 to rotate, which is used to grind the four sides of the board.

[0039] One end of the first drive slide rail 13 and the second drive slide rail 14 is provided with a first servo motor 17. The output end of the first servo motor 17 is connected to the lead screw 15. The lead screw 15 and the first slider 16 are threaded together.

[0040] The first servo motor 17 drives the lead screw 15 to run, and the transmission between the lead screw 15 and the first slider 16 drives the first adjusting slide rail 18 and the second adjusting slide rail 19 to adjust their positions, thereby moving each set of fixing frames 23 to the trimming start end close to each edge of the corresponding plate.

[0041] A second servo motor 22 is installed at one end of the first adjusting slide rail 18 and the second adjusting slide rail 19. The output end of the second servo motor 22 is connected to the first bidirectional lead screw 20. The first bidirectional lead screw 20 and the second slider 21 are threaded together.

[0042] The operation of the second servo motor 22 drives the first bidirectional lead screw 20 to rotate, thereby causing the two sets of fixed frames 23 located below the first adjusting slide rail 18 to move closer to each other, and also causing the two sets of fixed frames 23 located below the second adjusting slide rail 19 to move closer to each other, so that the grinding and trimming roller 25 contacts the four edges of the board.

[0043] The positioning and clamping mechanism includes a clamping adjustment rail 26 set on the top of the machine base 1. A second bidirectional lead screw 27 is rotatably mounted on the inner side of the clamping adjustment rail 26 and a third slider 28 is slidably mounted thereon. A clamping plate mounting bracket 29 is mounted on the top of the third slider 28. A third electric telescopic rod 30 is mounted on the side of the clamping plate mounting bracket 29. The piston rod end of the third electric telescopic rod 30 is connected to the positioning clamping plate 32. The third slider 28 and the second bidirectional lead screw 27 are threadedly connected. One end of the second bidirectional lead screw 27 passes through the side of the machine base 1 and is connected to the handwheel 31.

[0044] Rotating the second bidirectional lead screw 27 via handwheel 31 causes the two sets of third sliders 28 to move closer together via transmission between the second bidirectional lead screw 27 and the third slider 28. The movement of the third slider 28 causes the clamping plate mounting bracket 29, the third electric telescopic rod 30, and the positioning clamping plate 32 to move. When the positioning clamping plate 32 moves close to the four corners of the plate, the piston rod of the third electric telescopic rod 30 is extended, causing the positioning clamping plate 32 to move toward the plate. The plate is displaced by the pushing action of the positioning clamping plate 32, and personnel can assist in adjusting the position of the plate until the positioning clamping plate 32 clamps and positions the plate at the four corners.

[0045] The working principle and usage process of this utility model: This device is applied to the batch continuous trimming of multiple plates of the same specification. First, the position of the positioning clamp 32 is adjusted. A plate to be trimmed is placed on the top of the machine base 1. The second bidirectional lead screw 27 is rotated by the handwheel 31. Through the transmission between the second bidirectional lead screw 27 and the third slider 28, the left and right sets of third sliders 28 are driven to move closer to each other. The movement of the third sliders 28 drives the clamp mounting bracket 29, the third electric telescopic rod 30, and the positioning clamp 32 to move. When the positioning clamp 32 moves close to the four corners of the plate, the piston rod of the third electric telescopic rod 30 is extended, driving the positioning clamp 32 to move towards the plate. Through the pushing of the positioning clamp 32, the plate is moved... The material is then displaced, and personnel can assist in adjusting the position of the board until the positioning clamp 32 clamps and positions the four corners of the board. Then, the negative pressure pump 8 is controlled to draw negative pressure, causing the bottom of the board to adhere tightly to the adhesive pad 5 and be adsorbed and fixed. The first electric telescopic rod 2 is controlled to drive the mounting frame 3, connected to the lifting support 4, to rise, causing the board to rise synchronously and disengage from the inside of the positioning clamp 32, ensuring the positioning clamp 32 does not obstruct the trimming work. Then, the second electric telescopic rod 11 is controlled to drive the mounting plate 12 to descend, bringing the grinding and trimming roller 25 to the same horizontal line as the four sides of the board. The first servo motor 17 and the second servo motor 22 are controlled according to the board's dimensions. The first servo motor 17 drives the lead screw 15, which in turn drives the lead screw 15. The transmission between the first slider 16 and the first servo motor 5 drives the first adjusting slide rail 18 and the second adjusting slide rail 19 to adjust their positions, thereby moving each set of fixed brackets 23 to the trimming start end close to each edge of the corresponding board. The second servo motor 22 drives the first bidirectional lead screw 20 to rotate, causing the two sets of fixed brackets 23 below the first adjusting slide rail 18 to move closer together, and the two sets of fixed brackets 23 below the second adjusting slide rail 19 to move closer together, so that the grinding and trimming roller 25 contacts the four edges of the board. Then, the trimming drive motor 24 is turned on, driving the grinding and trimming roller 25 to rotate and grind the four edges of the board. The first servo motor 17 drives the lead screw 15 to move the first slider 16, which in turn moves the first adjusting slide rail 18. The second adjusting slide rail 19 connects to the fixed frame 23, the trimming drive motor 24, and the grinding and trimming roller 25, moving along the edge of the board to simultaneously grind all four edges, improving grinding and trimming efficiency. After grinding one board, the second electric telescopic rod 11 is controlled to drive the mounting plate 12 to rise and reset, and the negative pressure pump 8 is controlled to stop running. At this time, the board is no longer attracted and fixed, and the trimmed board can be directly removed. Then, the first electric telescopic rod 2 is controlled to drive the mounting frame 3 along with the lifting support 4 to descend and reset, allowing a board to be placed. The board is placed directly between the four sets of positioning clamps 32 for positioning, and the negative pressure pump 8 is controlled to run again to attract and fix the board. Then, the first electric telescopic rod 2 is controlled to drive the mounting frame 3 to rise again.The lifting support 4 moves upward, raising the board material, allowing the aforementioned grinding and trimming process to be repeated. This process is repeated until all boards of the same specifications in this batch have been ground and trimmed. Then, the position of the positioning clamp 32 can be readjusted according to the dimensions of the next batch of boards. In summary, this device can quickly position boards to be trimmed and simultaneously grind and trim all four edges of the board, greatly improving the efficiency of board trimming.
