Description

Technical Field

[0001] This invention belongs to the field of cutting technology, specifically a positioning and cutting device for cabinet production. Background Technology

[0002] Kitchen cabinets are the core of kitchen functionality and an important component of home space. They consist of cabinet bodies, doors, countertops, and hardware accessories. Their main function is to provide ample storage space and to achieve a rational layout for cooking, washing, and food preparation. The manufacturing of kitchen cabinets relies heavily on the precise cutting of various types of boards (such as particleboard, MDF, solid wood boards, and fire-resistant boards). This process is fundamental to manufacturing and is typically completed using equipment such as electronic panel saws and CNC machining centers. The cutting operation not only determines the basic dimensions and shape of the cabinet structure but also provides precise components for subsequent processes such as edge banding, drilling, grooving, and assembly. Efficient cutting solutions maximize material utilization and reduce waste, making them a key technological link in achieving mass production, standardization, and customization of kitchen cabinets.

[0003] A kitchen cabinet is typically made up of two identical top panels, side panels, and door panels, as well as two or more identical partitions. However, in traditional cutting production methods, when multiple identical top panels, side panels, door panels, or partitions need to be cut continuously from the same large sheet of material, existing equipment can usually only cut one at a time. This leads to repeated loading, positioning, and adjustments, resulting in frequent downtime and increased auxiliary time. Especially in mass production or with a high volume of customized orders, this repetitive operation significantly reduces processing efficiency, extends the production cycle, restricts capacity expansion, and reduces the efficiency and speed of kitchen cabinet processing. Therefore, improvements are needed to address these issues. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a positioning and cutting device for cabinet production, comprising a device base, an inverted L-shaped mounting beam fixedly installed on the middle of one side of the top of the device base, three horizontally synchronously adjustable n-shaped moving plates equally spaced on the inner side of the inverted L-shaped mounting beam, each n-shaped moving plate having a cutting wheel installed on its inner side, and an inner square tube rotatably mounted on the lower part of each n-shaped moving plate via bearings, the cutting wheel being fixedly installed on the middle of the surface of the inner square tube, and a square drive shaft penetrating the three inner square tubes being rotatably mounted on the inner side of the inverted L-shaped mounting beam. The top of the beam is equipped with a transmission mechanism 1 for synchronously and equally spaced adjustment of three n-shaped moving plates.

Three horizontally movable and adjustable drag plates are installed at equal distances between the two sliding rods 1. A fixing strip is fixedly installed on one side of each drag plate. A T-shaped push plate extending to the top of each fixing strip is installed on the top of each fixing strip. The bottom of the device platform is equipped with a transmission mechanism 2 for synchronously and equally spaced adjustment of the three drag plates. The transmission mechanism 2 is connected to the transmission mechanism 1.

[0005] Preferably, the top of each of the towing plates is provided with a cutting groove, and three cutting wheels are respectively located inside the three cutting grooves. The middle of the upper part of the inverted L-shaped mounting beam is provided with an adjustment groove that matches the n-shaped moving plate. A sliding rod II is fixedly installed inside the adjustment groove, and the upper parts of the three n-shaped moving plates are slidably sleeved on the sliding rod II.

[0006] Preferably, both transmission mechanism one and transmission mechanism two include three transmission plates and fixed plates. The six transmission plates are respectively fixedly installed on the top of the three n-shaped movable plates and the bottom of the three drag plates. The two fixed plates are respectively fixedly installed on the top of the inverted L-shaped mounting beam and the bottom of the device platform. Each of the six transmission plates has a sliding groove, and a slider is symmetrically slidably installed inside each of the six sliding grooves. Each of the two fixed plates has an adjustment mounting groove, and a bidirectional threaded shaft is rotatably installed inside each adjustment mounting groove. Movable sleeves are threadedly connected to both sides of the bidirectional threaded shaft. The four sliders on any two adjacent transmission plates and the two movable sleeves and two sliders on the fixed plate and the adjacent transmission plate are movably connected by an X-shaped movable frame.

[0007] Preferably, a scale is fixedly installed on one side of the inverted L-shaped mounting beam, and a scale pointer matching the scale is fixedly installed on one end of one of the transmission plates on the inverted L-shaped mounting beam. One end of each of the two bidirectional threaded shafts movably passes through the fixed plate and extends to one end of the device base. A sprocket is fixedly installed on one end of each of the two bidirectional threaded shafts, and a chain is installed between the two sprockets. A motor connected to the other end of the bidirectional threaded shaft on the fixed plate is installed on one end of one of the fixed plates.

[0008] Preferably, each of the three fixing strips has a long groove at its top, and a threaded rod is rotatably installed inside each of the three long grooves. The lower part of the T-shaped push plate is slidably installed inside the long groove and threadedly connected to the threaded rod. One end of the threaded rod extends to the outside of one end of the fixing strip and is fixedly installed with a bevel gear.

[0009] Preferably, a connecting shaft is rotatably mounted on one end of each of the three fixed plates, a bevel gear two that matches and meshes with bevel gear one is fixedly mounted on one end of each connecting shaft, and a gear is fixedly mounted on the other end of each connecting shaft.

[0010] Preferably, a gear column is rotatably mounted on one end of each mounting groove, and three gears are meshed with the gear column. The shaft end of the gear column extends movably to one side of the device base and is fixedly mounted with a sprocket three. A motor two is mounted on the inverted L mounting beam, and a sprocket four is fixedly mounted on the output end of the motor two. The spindle of the sprocket four movably passes through the inverted L mounting beam and is fixedly connected to one end of a square transmission shaft. A chain two is installed between the sprocket four and the sprocket three.

[0011] Compared with the prior art, the beneficial effects of the present invention are: (1) This positioning and cutting device has a multi-station synchronous cutting structure. This multi-station synchronous cutting structure can perform equal-interval cutting adjustment, so that batch cutting of cabinet panels can be carried out in one processing, which effectively improves the efficiency and speed of cabinet panel cutting and processing, shortens the cabinet production cycle, and increases the cabinet processing capacity. At the same time, this positioning and cutting device has an automatic pushing structure, which can push and move the panel to make the panel stable and safe for cutting. Its performance can meet the needs of cabinet production. (2) Place the large-size plate to be processed between the top of the device base and the three drag plates, and position the large-size plate between the three fixed strips and the three cutting wheels, while making the large-size plate contact one end of the inverted L-shaped mounting beam. Then, starting the motor and using two sprockets and a chain will cause the two bidirectional threaded shafts to rotate synchronously. The rotation of the bidirectional threaded shafts will cause the two movable sleeves on them to move relative to each other. The relative movement of the two movable sleeves on the bidirectional threaded shafts will drive the X-shaped movable frame connected to them to rotate and adjust. The rotation and adjustment of the X-shaped movable frame will drive the two sliders connected to it to move relative to each other and push the corresponding transmission plate to move. The movement of the transmission plate will drive the scale pointer to move synchronously. Then, by the scale indication of the scale pointer on the scale, the transmission plate and one end of the inverted L-shaped mounting beam can be precisely adjusted. The movement of this transmission plate will synchronously drive the other two transmission plates to adjust their positions synchronously and by the same distance through the other two X-shaped movable frames, so that the three transmission plates can move synchronously and by the same distance; the synchronous and same distance movement of the three transmission plates on the inverted L-shaped mounting beam and the three transmission plates on the device base will drive the three n-shaped moving plates and the three drag plates to move synchronously and by the same distance, so that the distance between the three cutting wheels and the inner end of the inverted L-shaped mounting beam is the same as the distance between any two adjacent cutting wheels; (3) Place the large-size plate to be processed between the surface of the first and second balls on the top of the device base and the three drag plates, and position the large-size plate between the three fixed strips and the three cutting wheels, and make the large-size plate contact one end of the inner side of the inverted L mounting beam; at the same time, adjust the position of the three cutting wheels and the three drag plates so that the distance between the three cutting wheels and the inner end of the inverted L mounting beam is the same as the distance between any two adjacent cutting wheels; and the movement of the three drag plates will drive the gear to slide on the gear column and maintain effective meshing connection; Then, start motor two, causing sprocket four to rotate. The rotation of sprocket four will drive the square drive shaft to rotate, which in turn will drive the three cutting wheels to rotate through the inner square tube. The rotation of sprocket four will drive the gear column to rotate through chain two and sprocket three. The rotation of the gear column will drive the three gears to rotate, which in turn will drive the bevel gear two to rotate. The rotation of bevel gear two will drive the bevel gear one to rotate, which will drive the threaded rod to rotate. The rotation of the threaded rod will move the T-shaped push plate, which will move the T-shaped push plate towards the large-sized plate and push the large-sized plate towards the three rotating cutting wheels. At the same time, the large-sized plate will be manually supported to move it stably towards the cutting wheels. Then, the rotating cutting wheels will cut multiple pieces of the large-sized plate to the required size. Attached Figure Description

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0015] This positioning and cutting device features a multi-station synchronous cutting structure, which allows for equidistant cutting adjustments. This enables batch cutting of cabinet panels in a single process, effectively improving the efficiency and speed of cabinet panel cutting, shortening the cabinet production cycle, and increasing cabinet processing capacity. Furthermore, the device has an automatic pushing structure that pushes and moves the panels, ensuring stable and safe cutting. The device's simple design makes positioning and cutting convenient, convenient, stable, and reliable, meeting the performance requirements of cabinet production.

[0016] Example 1, by Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The present invention includes a device base 1. An inverted L-shaped mounting beam 2 is fixedly installed in the middle of one side of the top of the device base 1. Three horizontally adjustable n-shaped moving plates 3 are installed at equal intervals on the inner side of the inverted L-shaped mounting beam 2. The distance between the n-shaped moving plate 3 near the motor 37 and the inverted L-shaped mounting beam 2 is the same as the distance between any two adjacent n-shaped moving plates 3. A cutting wheel 4 is installed on the inner side of each n-shaped moving plate 3, and an inner square tube 5 is rotatably installed on the lower part of each n-shaped moving plate 3 through a bearing. The cutting wheel 4 is fixedly installed in the middle of the surface of the inner square tube 5. An adjustment groove 15 matching the n-shaped moving plate 3 is opened in the middle of the upper part of the inverted L-shaped mounting beam 2. A sliding rod 16 is fixedly installed inside the adjustment groove 15. The upper parts of the three n-shaped moving plates 3 are slidably sleeved on the sliding rod 16, thereby effectively installing the n-shaped moving plates 3.

[0017] Furthermore, a square drive shaft 6 that passes through three inner square tubes 5 is rotatably mounted on the inner side of the inverted L-shaped mounting beam 2, and a transmission mechanism 7 is provided on the top of the inverted L-shaped mounting beam 2 to synchronously and equally adjust the three n-shaped moving plates 3.

[0018] The device base 1 has a vertically through mounting groove 8 in the middle. Two sliding rods 9 are fixedly installed in the middle of the mounting groove 8. Three horizontally adjustable drag plates 10 are installed at equal distances between the two sliding rods 9. Each drag plate 10 has a cutting groove 11 on its top. Three cutting wheels 4 are located inside the three cutting grooves 11, so that the cutting wheels 4 can effectively cut the material on the drag plate 10.

[0019] Each of the three towing plates 10 is fixedly installed with a fixing strip 12 on one side. Each of the fixing strips 12 is equipped with a T-shaped push plate 13 extending to the top of the device base 1. The bottom of the device base 1 is provided with a transmission mechanism 2 14 for synchronous and equal-distance adjustment of the three towing plates 10. The transmission mechanism 2 14 is connected to the transmission mechanism 1 7.

[0020] Example 2, based on Example 1, is... Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, both transmission mechanism 1 7 and transmission mechanism 2 14 include three transmission plates 17 and fixed plates 18. The six transmission plates 17 are respectively fixedly installed on the top of the three n-shaped moving plates 3 and the bottom of the three drag plates 10, and the two fixed plates 18 are respectively fixedly installed on the top of the inverted L-shaped mounting beam 2 and the bottom of the device platform 1.

[0021] Each of the six transmission plates 17 has a sliding slot 19, and each of the six sliding slots 19 has a slider 20 symmetrically slidably mounted inside. Each of the two fixed plates 18 has an adjustment mounting slot 21, and each of the adjustment mounting slots 21 has a bidirectional threaded shaft 22 rotatably mounted inside. Each of the two bidirectional threaded shafts 22 has a movable sleeve 23 threadedly connected to both sides. The four sliders 20 on any two adjacent transmission plates 17 and the two movable sleeves 23 and two sliders 20 on the fixed plate 18 and the adjacent transmission plate 17 are movably connected by an X-shaped movable frame 24, so that equal-interval adjustment can be effectively performed.

[0022] A scale 201 is fixedly installed on one side of the inverted L-shaped mounting beam 2. The starting end of the scale 201 is aligned with the end of the inner side of the inverted L-shaped mounting beam 2 that is close to the motor 37. One end of one of the transmission plates 17 on the inverted L-shaped mounting beam 2 is fixedly installed with a scale pointer 1701 that matches the scale 201, so that the cutting distance can be precisely adjusted.

[0023] One end of each of the two bidirectional threaded shafts 22 movably passes through the fixed plate 18 and extends to one end of the device base 1. A sprocket 25 is fixedly installed at one end of each of the two bidirectional threaded shafts 22. A chain 26 is installed between the two sprockets 25. A motor 27 connected to the other end of the bidirectional threaded shaft 22 on one of the fixed plates 18 is installed at one end of the fixed plate 18, thereby enabling the cutting wheel 4 and the drag plate 10 to be adjusted synchronously and at equal intervals.

[0024] Specifically, the large-sized plate to be processed is placed between the top of the device base 1 and the three drag plates 10, and the large-sized plate is positioned between the three fixed strips 13 and the three cutting wheels 4, while the large-sized plate is in contact with one end of the inner side of the inverted L-shaped mounting beam 2. Then, starting the motor 27 and using the two sprockets 25 and the chain 26 will cause the two bidirectional threaded shafts 22 to rotate synchronously. The rotation of the bidirectional threaded shafts 22 will cause the two movable sleeves 23 on them to move relative to each other. The relative movement of the two movable sleeves 23 on the bidirectional threaded shafts 22 will drive the X-shaped movable frame 24 connected to it to rotate and adjust. The rotation and adjustment of the X-shaped movable frame 24 will drive the two sliders 20 connected to it to move relative to each other and push the corresponding transmission plate 17 to move. The movement of the transmission plate 17 will drive the scale pointer 1701 to move synchronously. Then, through the scale indication of the scale pointer 1701 on the scale 201, the transmission plate 17 and one end of the inverted L-shaped mounting beam 2 can be precisely adjusted in position. The movement of the transmission plate 17 will synchronously drive the other two transmission plates 17 to adjust their positions synchronously and at the same distance through the other two X-shaped movable frames 24, so that the three transmission plates 17 can move synchronously and at the same distance. The synchronous and same-distance movement of the three transmission plates 17 on the inverted L-shaped mounting beam 2 and the three transmission plates 17 on the device base 1 will drive the three n-shaped moving plates 3 and the three drag plates 10 to move synchronously and at the same distance, so that the distance between the three cutting wheels 4 and the inner end of the inverted L-shaped mounting beam 2 is the same as the distance between any two adjacent cutting wheels 4.

[0025] Example 3, based on Example 1, is... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, each of the three fixed plate strips 12 has a long groove 28 on its top, and a threaded rod 29 is rotatably installed inside each of the three long grooves 28. The lower part of the T-shaped push plate 13 is slidably installed inside the long groove 28 and threadedly connected to the threaded rod 29. One end of the threaded rod 29 extends to the outside of one end of the fixed plate strip 12 and is fixedly installed with a bevel gear 30.

[0026] Each of the three fixed plate strips 12 has a connecting shaft rotatably mounted on one end. A bevel gear 31, matching and meshing with bevel gear 30, is fixedly mounted on one end of each connecting shaft. A gear 32 is fixedly mounted on the other end of each connecting shaft. A gear column 33 is rotatably mounted on one end of each mounting groove 8. All three gears 32 mesh with the gear column 33. The shaft end of the gear column 33 extends movably to one side of the device base 1 and is fixedly mounted with a sprocket 34. A motor 37 is mounted on the inverted L-shaped mounting beam 2. A sprocket 35 is fixedly installed at the output end of sprocket 37. The spindle of sprocket 35 moves through the inverted L-shaped mounting beam 2 and is fixedly connected to one end of the square drive shaft 6. A chain 36 is installed between sprocket 35 and sprocket 34, which can effectively move and cut multiple pieces of the placed plate to the required specifications. Ball bearings 38 are installed at equal distances on both sides of the top of the device platform 1, and ball bearings 39 are installed at equal distances on both sides of the top of the drag plate 10, which can push and move the placed plate.

[0027] Specifically, the large-size plate to be processed is placed between the surfaces of the first ball 38 and the second ball 39 on the top of the device base 1 and the three drag plates 10, and the large-size plate is positioned between the three fixed strips 13 and the three cutting wheels 4, and the large-size plate is in contact with one end of the inner side of the inverted L-shaped mounting beam 2. Meanwhile, by adjusting the positions of the three cutting wheels 4 and the three drag plates 10, the distance between the three cutting wheels 4 and the inner end of the inverted L-shaped mounting beam 2 is the same as the distance between any two adjacent cutting wheels 4; and the movement of the three drag plates 10 will drive the gear 32 to slide on the gear column 33 and maintain effective meshing connection. Then, start motor 2 37 to rotate sprocket 4 35. The rotation of sprocket 4 35 will drive square drive shaft 6 to rotate. The rotation of square drive shaft 6 will drive three cutting wheels 4 to rotate through inner square tube 5. The rotation of sprocket 4 35 will drive tooth column 33 to rotate through chain 2 36 and sprocket 34. The rotation of tooth column 33 will drive three gears 32 to rotate. The rotation of three gears 32 will drive bevel gear 2 31 to rotate. The rotation of bevel gear 2 31 will drive bevel gear 1 30 to rotate, which will drive threaded rod 29 to rotate. The rotation of threaded rod 29 will move T-shaped push plate 13, which will move towards the large-size plate and push the large-size plate towards the three rotating cutting wheels 4. At the same time, the large-size plate is manually supported to move it stably towards the cutting wheels 4. Then the rotating cutting wheels 4 will cut multiple pieces of the large-size plate to the required size.
