Description

Technical Field

[0001] This utility model relates to the technical field of decorative panel processing equipment, and in particular to a rapid positioning and cutting structure for decorative panels. Background Technology

[0002] The rapid positioning and cutting structure for decorative panels is a specialized piece of equipment used in decoration, furniture manufacturing, and other fields for processing decorative panels. Its core function is to precisely fix the panel's position through a positioning mechanism, which, in conjunction with the cutting mechanism, enables automated, high-precision cutting. It can cut panels of different sizes and shapes according to design requirements and is widely used in home decoration sites, panel processing plants, and furniture production workshops. This structure can replace traditional manual marking and cutting, significantly improving panel processing efficiency and precision, and is a key piece of equipment for ensuring the quality of decoration projects and reducing labor costs. However, existing decorative panel cutting equipment has significant shortcomings in practical use.

[0003] On the one hand, the positioning accuracy is low and the operation is cumbersome. Traditional cutting equipment mostly uses manual fixation of the board, which requires repeated measurement and marking during positioning, which is prone to positioning deviation, resulting in inconsistent board size after cutting and poor adaptability.

[0004] On the other hand, the cutting efficiency is low and the safety is insufficient. Traditional equipment is mostly single-station cutting, and the board is prone to displacement due to vibration during the cutting process, resulting in low efficiency. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a rapid positioning and cutting structure for decorative panels, which overcomes the shortcomings of the prior art and effectively solves the problems of low positioning accuracy, cumbersome operation and low efficiency of cutting equipment in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A rapid positioning and cutting structure for decorative panels includes a placement platform. Right-angle frames are welded and fixed to both rearward sides of the top of the placement platform, and a cutting mechanism is welded and fixed to one end of each of the two right-angle frames. A positioning mechanism is welded and fixed to the top of the placement platform between the two right-angle frames. The cutting mechanism includes a U-shaped frame, threaded rods rotatably connected to the inner walls of both ends of the U-shaped frame, auxiliary rods evenly distributed around the threaded rods along a ring and welded and fixed to the inner walls of both ends of the U-shaped frame, a corrugated tube sleeved on the outside of the threaded rods and auxiliary rods, and a cutting assembly connected to the walls of the threaded rods and auxiliary rods. The cutting assembly includes a movable block, a first push rod motor fixed to the bottom of the movable block, a cutter fixed to the bottom of the first push rod motor, and telescopic rods respectively connected and fixed between the top two ends of the cutter and the bottom two ends of the movable block. The positioning mechanism includes a fixed plate, a second push rod motor fixed to the front of the fixed plate, a positioning plate fixed to one end of the second push rod motor, F-shaped frames respectively welded and fixed to the top two ends of the positioning plate, a connecting plate inserted into the two F-shaped frames, a third push rod motor fixed to the bottom of the connecting plate, and a pressure plate fixed to the bottom of the third push rod motor. Furthermore, the top of the placement platform has a strip-shaped opening, and the width of the strip-shaped opening is greater than the width of the cutter.

[0007] The slotted opening provides cutting space for the cutter, preventing it from colliding and being damaged by the placement platform. It also allows cutting debris to fall through the slot into the collection device below, reducing dust pollution.

[0008] Furthermore, the two ends of the two bellows are respectively fixed between the outer wall of the movable block and the inner wall of the U-shaped frame, and a servo motor is installed and fixed on the outer wall of one end of the U-shaped frame. The output shaft of the servo motor is connected and fixed to one end of the threaded rod through a coupling.

[0009] The corrugated tube can wrap around the threaded rod and auxiliary rod to prevent cutting debris from adhering and affecting the sliding of the parts; the servo motor provides power to the threaded rod, and by precisely controlling the speed, it drives the cutting components to move smoothly, achieving uniform speed cutting of the sheet metal and improving cutting accuracy. Furthermore, the movable block is screwed to the threaded rod, and the movable block is slidably connected to the four auxiliary rods.

[0010] The screwed connection between the movable block and the threaded rod converts the rotational motion of the threaded rod into the linear motion of the movable block; the four auxiliary rods are arranged in a ring to guide the movable block, prevent the movable block from rotating synchronously with the threaded rod, and ensure that the cutting assembly moves smoothly.

[0011] Furthermore, a first guide rod is welded and fixed to both ends of the back of the positioning plate, and a first through hole adapted to the first guide rod is opened at both ends of the front of the fixing plate. A second guide rod is welded and fixed to both ends of the top of the pressure plate, and a second through hole adapted to the second guide rod is opened at both ends of the top of the connecting plate.

[0012] The fit between the first guide rod and the first through hole ensures that the positioning plate remains horizontal when it moves with the second push rod motor, avoiding positioning deviation; the fit between the second guide rod and the second through hole ensures that the pressure plate moves vertically when it rises and falls with the third push rod motor, evenly pressing the plate and preventing the plate from shifting.

[0013] Furthermore, the top of the F-shaped frame and both ends of the top of the connecting plate are provided with insertion holes, and insertion rods are inserted into the insertion holes.

[0014] The F-frame provides support for the connecting plate. After the insertion rod is inserted into the insertion hole, it can fix the relative position of the connecting plate and the F-frame, preventing the connecting plate from shaking when the pressure plate presses the plate.

[0015] The beneficial effects of this utility model are as follows: With high positioning accuracy and convenient operation, the automated positioning mechanism and guide structure solve the problems of poor positioning and complicated operation of traditional equipment. The second push rod motor drives the positioning plate to accurately position, and the third push rod motor drives the pressure plate to quickly press the plate, greatly shortening the single positioning time. The first guide rod and the second guide rod ensure that there is no deviation in the positioning and pressing process, and can be adapted to plates of different thicknesses without replacing parts, thus improving adaptability compared to traditional equipment. With high cutting efficiency and good safety, relying on the dual cutting mechanism and protective design, it improves the low efficiency and poor safety of traditional equipment. The dual cutting mechanism can cut both sides or different positions of the plate at the same time. With the uniform speed cutting driven by the servo motor, the efficiency is greatly improved. The corrugated pipe protects the threaded rod and auxiliary rod, and the strip-shaped opening collects debris, reducing the impact of dust on the parts. No manual supervision is required during the cutting process, avoiding operator contact with the cutting area, significantly improving safety and meeting the requirements of safe production.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0019] Reference Figure 1-4 A rapid positioning and cutting structure for decorative panels includes a placement platform 1. Right-angle frames 2 are welded and fixed to both rear sides of the top of the placement platform 1. A cutting mechanism 3 is welded and fixed to one end of the top of each of the two right-angle frames 2. A positioning mechanism 4 is welded and fixed to the top of the placement platform 1 between the two right-angle frames 2. The cutting mechanism 3 includes a U-shaped frame 5, threaded rods 6 rotatably connected to the inner walls of both ends of the U-shaped frame 5, auxiliary rods 8 evenly distributed around the threaded rods 6 along a ring and welded and fixed to the inner walls of both ends of the U-shaped frame 5, a corrugated pipe 9 sleeved and movable outside the threaded rods 6 and auxiliary rods 8, and a cutting assembly 10 connected to the walls of the threaded rods 6 and auxiliary rods 8. The cutting assembly 10 includes a movable block 1. 1. A first push rod motor 12 is installed and fixed to the bottom of the movable block 11. A cutter 13 is installed and fixed to the bottom of the first push rod motor 12. Telescopic rods 14 are respectively connected and fixed between the top two ends of the cutter 13 and the bottom two ends of the movable block 11. The positioning mechanism 4 includes a fixed plate 15, a second push rod motor 16 installed and fixed to the front of the fixed plate 15, a positioning plate 17 installed and fixed to one end of the second push rod motor 16, F-shaped frames 19 respectively welded and fixed to the top two ends of the positioning plate 17, a connecting plate 20 inserted into the two F-shaped frames 19, a third push rod motor 21 installed and fixed to the bottom of the connecting plate 20, and a pressure plate 22 installed and fixed to the bottom of the third push rod motor 21. The top of the placement platform 1 has a strip-shaped opening, the width of which is greater than the width of the cutter 13. The strip-shaped opening provides cutting space for the cutter 13, preventing it from colliding and being damaged by the cutter 13 with the placement platform 1. At the same time, it allows cutting debris to fall through the strip-shaped opening to the collection device below, reducing dust pollution. The two ends of the two corrugated pipes 9 are respectively fixed between the outer wall of the movable block 11 and the inner wall of the U-shaped frame 5. A servo motor 7 is installed and fixed on the outer wall of one end of the U-shaped frame 5. The output shaft of the servo motor 7 is connected and fixed to one end of the threaded rod 6 through a coupling. The corrugated pipes 9 can wrap around the threaded rod 6 and the auxiliary rod 8. To prevent cutting debris from adhering and affecting the sliding of components, the servo motor 7 provides power to the threaded rod 6. By precisely controlling the rotation speed, it drives the cutting assembly 10 to move smoothly, achieving uniform speed cutting of the sheet metal and improving cutting accuracy. The movable block 11 is screwed to the threaded rod 6 and slidably connected to the four auxiliary rods 8. The screwed connection between the movable block 11 and the threaded rod 6 converts the rotational motion of the threaded rod 6 into the linear motion of the movable block 11. The four auxiliary rods 8 are arranged in a ring to guide the movable block 11 and prevent it from rotating synchronously with the threaded rod 6, ensuring that the cutting assembly 10 moves smoothly.

[0020] The positioning plate 17 has a first guide rod 18 welded and fixed at both ends of its back. The fixing plate 15 has a first through hole adapted to the first guide rod 18 at both ends of its front. The pressure plate 22 has a second guide rod 23 welded and fixed at both ends of its top. The connecting plate 20 has a second through hole adapted to the second guide rod 23 at both ends of its top. The cooperation between the first guide rod 18 and the first through hole ensures that the positioning plate 17 remains horizontal when it moves with the second push rod motor 16, avoiding positioning deviation. The cooperation between the second guide rod 23 and the second through hole ensures that the pressure plate 22 moves vertically when it rises and falls with the third push rod motor 21, evenly pressing the plate and preventing the plate from shifting. The top of the F-shaped frame 19 and the top of the connecting plate 20 have insertion holes at both ends. Insert rods are inserted into the insertion holes. The F-shaped frame 19 provides support for the connecting plate 20. After the insertion rod is inserted into the insertion hole, it can fix the relative position of the connecting plate 20 and the F-shaped frame 19, preventing the connecting plate 20 from shaking when the pressure plate 22 presses the plate.

[0021] For the placement platform and foundation support: Placement platform 1 is made of 15mm thick Q235 cold-rolled steel plate with electrostatic powder coating, which is highly corrosion resistant and can be used for a long time in humid processing environments. The top of placement platform 1 has a strip opening, and a debris collection box is installed below it through a bracket. Debris can fall naturally into the collection box through the strip opening for easy centralized cleaning. The right-angle frame 2 is welded to the two sides of the top rear of placement platform 1 with full welding. The weld leg height is 8mm. The weld is inspected to ensure that there is no false welding. The top of the right-angle frame 2 is fixed to the U-shaped frame 5 of the cutting mechanism 3 with M12 bolts to ensure the stability of the cutting mechanism. For the cutting mechanism and drive unit: The U-shaped frame 5 of the cutting mechanism 3 is rotatably connected to the threaded rod 6 at both ends by deep groove ball bearings. The radial clearance of the bearings is ≤0.02mm. Lithium-based grease is applied, and the rotational resistance is ≤10N. The auxiliary rods 8 distributed in a ring around the threaded rod 6 are fully welded to the inner walls at both ends of the U-shaped frame 5. The surface of the auxiliary rods 8 is polished to ensure smooth sliding of the movable block 11. The servo motor 7 is mounted on the outer wall of one end of the U-shaped frame 5 through an L-shaped bracket. The output shaft is connected to the threaded rod 6 through a plum blossom coupling. The coupling allows a radial deviation of ≤0.1mm to reduce vibration transmission. The motor achieves precise speed and direction control through a PLC controller, driving the cutting assembly 10 to move along the threaded rod 6. For the cutting assembly and protective parts: the movable block 11 of the cutting assembly 10 is screwed to the threaded rod 6 and slides with the auxiliary rod 8. The first push rod motor 12 is installed at the bottom of the movable block 11 by M8 bolts. The output shaft is fixed to the cutter 13 by the flange. The telescopic rod 14 connects the top two ends of the cutter 13 and the bottom two ends of the movable block 11 to ensure that the cutter 13 remains vertical when it is raised and lowered, so as to avoid the saw blade tilting and causing the cutting surface to be uneven. The corrugated tube 9 sleeved on the outside of the threaded rod 6 and the auxiliary rod 8 is fixed at both ends to the outer wall of the movable block 11 and the inner wall of the U-shaped frame 5 by clamps respectively. The corrugated tube 9 can move and extend with the movable block 11, completely covering the parts and preventing debris from entering and affecting the sliding.

[0022] For the positioning mechanism and pressing part: the fixing plate 15 of the positioning mechanism 4 is fully welded to the placement platform 1. The second push rod motor 16 is installed on the front of the fixing plate 15 by M8 bolts. The output shaft is welded to the positioning plate 17. The first guide rod 18 welded to both ends of the back of the positioning plate 17 slides with the first through hole of the fixing plate 15 to ensure that the positioning plate 17 moves smoothly. The F-shaped frame 19 welded to both ends of the top of the positioning plate 17 is aligned with the insertion hole of the connecting plate 20. After the insertion rod is inserted, the position of the connecting plate 20 is fixed. The third push rod motor 21 installed at the bottom of the connecting plate 20 by M8 bolts has its output shaft fixed to the pressure plate 22. The friction coefficient of the rubber pad is ≥0.8 to prevent slippage when pressing the plate. The second guide rod 23 welded to both ends of the top of the pressure plate 22 slides with the second through hole of the connecting plate 20 to ensure that the pressure plate 22 presses the plate evenly.

[0023] Working principle: Equipment debugging and parameter setting: Debug according to the specifications of the decorative board to be cut; adjust the position of the connecting plate 20 within the F-frame 19 so that the height of the pressure plate 22 matches the thickness of the board, and insert the plug rod to fix the connecting plate 20; set the parameters through the PLC controller: the second push rod motor 16 pushes the positioning plate 17 to a position 1800mm away from the cutting line, the third push rod motor 21 sets the clamping force to 150N, the first push rod motor 12 sets the descending height of the cutter 13 (the saw blade penetrates 2mm into the board), and the servo motor 7 sets the moving speed of the cutting component 10 to 10mm / s, completing the debugging; Panel positioning and clamping: Place the decorative panel on top of the placement platform 1, with one end of the panel attached to the positioning plate 17 (not extended). Start the second push rod motor 16 to push the positioning plate 17 and move the panel to the preset cutting position. The first guide rod 18 ensures that the positioning plate 17 moves horizontally without deviation. Start the third push rod motor 21 to move the pressure plate 22 downward until the rubber pad is pressed tightly against the surface of the panel. The second guide rod 23 ensures that the pressure plate 22 is pressed vertically and the panel is not tilted or offset, thus completing the positioning and clamping. Automatic plate cutting process: The cutter 13 is started, and the saw blade rotates at high speed (3000 r / min). The first push rod motor 12 is started, which drives the cutter 13 to move downward. The saw blade contacts the plate and begins cutting. At the same time, the servo motor 7 is started, which drives the movable block 11 to move smoothly along the threaded rod 6 and the auxiliary rod 8. The cutting component 10 moves synchronously with the movable block 11 to achieve continuous cutting of the plate. The debris generated by cutting falls into the collection box through the strip opening of the placement table 1. The corrugated pipe 9 prevents debris from adhering to the threaded rod and the auxiliary rod, ensuring smooth sliding of the components. When the cutting component 10 moves to the preset cutting endpoint, the first push rod motor 12 drives the cutter 13 to rise and detach from the plate. The servo motor 7 stops, the cutter 13 is turned off, and one cutting operation is completed. Sheet removal and equipment maintenance: After cutting, the third push rod motor 21 drives the pressure plate 22 to rise, releasing the sheet. The cut sheet is then removed manually or by a robotic arm. The second push rod motor 16 drives the positioning plate 17 to reset, preparing for the cutting of the next sheet. During routine maintenance, the debris collection box is cleaned regularly (once a day), the wear of the saw blade 13 is checked (if the saw teeth wear is ≥1mm, it is replaced), the grease on the threaded rod 6 and the auxiliary rod 8 is replenished (once a week), and the operating noise of the push rod motor and the servo motor is checked (if the noise exceeds the standard, check the bearing wear) to ensure long-term stable operation of the equipment. The entire process achieves rapid positioning, efficient cutting, and safety protection of decorative sheets, meeting the needs of large-scale processing.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
