Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production and processing technology, and in particular to a nonwoven fabric production and cutting device. Background Technology

[0002] Nonwoven fabrics, as a type of non-woven material, are widely used in many fields such as medical and health care, agriculture, industrial packaging, and household goods due to their lightweight, breathability, moisture resistance, and environmental friendliness. With the continuous growth of demand from downstream industries, the production scale of nonwoven fabrics continues to expand, and the requirements for its processing efficiency and cutting quality are also increasing.

[0003] Currently, existing nonwoven fabric cutting equipment has many limitations in practical applications: traditional single-blade cutting equipment needs to complete multiple positions of cutting one by one, which is inefficient and difficult to meet the needs of mass production. Although some multi-blade cutting equipment can achieve multi-position cutting, the adjustment of the cutting blade spacing is cumbersome and requires manual adjustment one by one, which is complicated to operate.

[0004] Therefore, those skilled in the art have provided a nonwoven fabric production cutting apparatus to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a non-woven fabric production cutting device. Through the coordinated operation of multiple cutting components, a linkage structure is formed by a fixed plate, a support plate, and a connecting rod. With the help of a screw, a cylinder, and a motor drive, the cutting blade position can be adjusted, lifted, and moved for cutting. The spacing between multiple cutting blades can be quickly adjusted to achieve one-time multi-position cutting, which greatly improves production efficiency compared with traditional single-blade cutting equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A nonwoven fabric production cutting device includes a processing table, a fixed frame is fixedly connected to one side of the upper end of the processing table, and a cutting component is arranged between the processing table and the fixed frame.

[0008] The cutting assembly includes multiple fixed plates, multiple first support plates, multiple connecting plates, and multiple connecting rods. Each connecting rod is rotatably connected to a corresponding connecting plate. A second support plate is fixedly connected to the rear end of one of the fixed plates. Multiple first support plates are fixedly connected to their respective fixed plates. An adjustment groove and two positioning grooves are provided at the upper end of the processing table. An adjustment screw is rotatably connected between the inner walls of both sides of the adjustment groove. An adjustment slider is threaded onto the outer wall of the adjustment screw. Positioning rods are fixedly connected between the inner walls of both sides of the two positioning grooves. Positioning sliders are slidably fitted onto the outer walls of both positioning rods. Cylinders are fixedly installed at the upper center of each of the multiple fixed plates. The telescopic ends of each of the multiple cylinders penetrate the corresponding fixed plate and are fixedly connected to a lifting seat. A controller and a first motor are fixedly installed at the front and rear of one side of the processing table, respectively. A second motor is fixedly installed at the front end of each of the multiple lifting seats.

[0009] Through the above technical solution, the cutting components work together, with the fixed plate, support plate, connecting rod and other components forming a linkage structure. With the help of lead screw, cylinder, motor and other drive, the position adjustment, lifting and lowering and moving cutting action of the cutting blade can be realized. By quickly adjusting the spacing of multiple cutting blades, multi-position cutting can be realized at one time, which greatly improves production efficiency compared with traditional single-blade cutting equipment.

[0010] Furthermore, multiple positioning sleeves are fixedly connected to both sides of the lower end of the multiple lifting seats, and movable columns are slidably arranged inside the multiple positioning sleeves. Positioning pressure plates are fixedly connected to the lower ends of the multiple movable columns located on the same side, and telescopic springs are fixedly connected between the inner walls of the opposite ends of the multiple movable columns and the corresponding positioning sleeves.

[0011] With the above technical solution, when the cylinder drives the lifting seat to descend, the positioning sleeve moves down synchronously with the lifting seat. Since the positioning pressure plate at the lower end of the movable column contacts the surface of the non-woven fabric first, the movable column slides upward relative to the positioning sleeve under the action of material resistance, compressing the internal telescopic spring. The elastic force generated by the spring is evenly applied to the surface of the non-woven fabric through the positioning pressure plate, forming a stable pre-tightening force to pre-press and fix the non-woven fabric, which can effectively prevent the material from slipping or wrinkling due to the lateral force generated by the blade cutting during the cutting process.

[0012] Furthermore, each of the multiple lifting seats has a moving groove at the lower center, and a moving screw is rotatably connected between the front and rear inner walls of the multiple moving grooves. A moving slider is threaded onto the outer wall of each of the multiple moving screws. Each of the multiple moving sliders slides within the corresponding moving groove. A cutting blade is fixedly connected to the lower end of each of the multiple moving sliders. The output ends of the multiple second motors pass through the corresponding lifting seats and are fixedly connected to the corresponding moving screws.

[0013] With the above technical solution, when the motor starts, it drives the lead screw to rotate, and the cutting blade can be moved by the provided movable slider, thereby realizing the cutting action of non-woven fabric.

[0014] Furthermore, positioning telescopic rods are fixedly connected to the upper front and rear ends of the multiple fixed plates, and the telescopic ends of the multiple positioning telescopic rods penetrate the corresponding fixed plates and are fixedly connected to the corresponding lifting seats.

[0015] The above technical solution, with its positioning telescopic rod, makes the lifting process of the lifting seat more stable.

[0016] Furthermore, the output end of the first motor passes through the processing table and is fixedly connected to the adjusting screw. The first motor, multiple cylinders, and multiple second motors are all electrically connected to the controller.

[0017] Through the above technical solution, the controller acts as the command center, outputting electrical signals to control the start, stop, speed, extension and retraction of the first motor (adjusting the position of the cutting component), the cylinder (driving the lifting), and the second motor (driving the movement of the cutting blade).

[0018] Furthermore, each of the plurality of fixed plates and fixed frames has a sliding groove near the corresponding connecting plate, and a sliding rod is fixedly connected between the front and rear inner walls of the plurality of sliding grooves. A sliding block is slidably sleeved on the outer wall of each of the plurality of sliding rods. Each of the plurality of sliding blocks is fixedly connected to the corresponding connecting plate. Two adjacent connecting rods are rotatably connected. The adjusting slider and the second support plate are fixedly connected. Both of the positioning sliders are fixedly connected to the corresponding first support plate.

[0019] Through the above technical solution, multiple connecting rods and the fixed frame form a hinged structure. When the adjusting screw drives the adjusting slider to move, the adjusting slider drives the fixed plate connected to it to move horizontally through the second support plate. The movement of the fixed plate is transmitted to other fixed plates through the connecting rods, so that all fixed plates move synchronously and at equal distances. The positioning slider slides on the positioning rod to provide auxiliary support for the fixed plate group and ensure its stability during movement.

[0020] Furthermore, an industrial rubber plate is provided at the upper center of the processing table;

[0021] Through the above technical solution, an industrial rubber sheet is laid on the upper part of the processing table. Utilizing the elasticity and wear resistance of rubber, it can withstand the impact of the cutting blade. Moreover, the hardness of rubber is lower than that of the cutting blade, which can avoid damage to the blade. Its wear-resistant properties can resist repeated cutting by the blade. After long-term use, only the surface layer of the rubber sheet needs to be replaced, reducing equipment maintenance costs.

[0022] Furthermore, an end positioning plate is fixedly connected to the upper end of the processing table near the fixed frame;

[0023] With the above technical solution, the end positioning plate is vertically fixed to the side of the processing table near the fixed frame. During the nonwoven fabric feeding process, the end of the material is aligned with the positioning plate to achieve end alignment positioning.

[0024] This utility model has the following beneficial effects:

[0025] 1. The nonwoven fabric production cutting device proposed in this utility model, through the coordinated operation of multiple cutting components, forms a linkage structure with a fixed plate, a support plate, and a connecting rod. With the help of a lead screw, a cylinder, and a motor drive, it realizes the adjustment, lifting, and moving cutting of the cutting blade position. It can quickly adjust the spacing between multiple cutting blades to achieve one-time multi-position cutting, which greatly improves the production efficiency compared with traditional single-blade cutting equipment. At the same time, the positioning pressure plate combined with the telescopic spring pre-compresses the material to avoid slippage and wrinkles during cutting, ensuring the cutting quality. It achieves dual optimization of high efficiency and high quality in the nonwoven fabric production cutting process. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Reference Figure 1-6 This utility model provides a specific embodiment: a non-woven fabric production cutting device, including a processing table 1, a fixed frame 2 fixedly connected to one side of the upper end of the processing table 1, a cutting component 3 arranged between the processing table 1 and the fixed frame 2, an industrial rubber plate 27 arranged in the middle of the upper end of the processing table 1, the industrial rubber plate 27 is laid on the upper end of the processing table 1, utilizing the elasticity and wear resistance of rubber to withstand the impact of the cutting blade 19 falling, and the hardness of the rubber is lower than that of the cutting blade 19, which can avoid damage to the blade body. Its wear resistance can resist repeated cutting by the blade. After long-term use, only the surface layer of the rubber plate needs to be replaced, reducing equipment maintenance costs. An end positioning plate 28 is fixedly connected to the upper end of the processing table 1 near the fixed frame 2. The end positioning plate 28 is vertically fixed to the side of the processing table 1 near the fixed frame 2. During the non-woven fabric feeding process, the end of the material is aligned with the positioning plate to achieve end alignment positioning.

[0036] The cutting assembly 3 includes multiple fixed plates 4, multiple first support plates 5, multiple connecting plates 33, and multiple connecting rods 7. Each connecting rod 7 is rotatably connected to a corresponding connecting plate 33. A second support plate 6 is fixedly connected to the rear end of one of the fixed plates 4. Each of the multiple first support plates 5 is fixedly connected to a corresponding fixed plate 4. The upper end of the processing table 1 has an adjustment groove 8 and two positioning grooves 11. An adjustment screw 9 is rotatably connected between the inner walls of both sides of the adjustment groove 8. An adjustment slider 10 is threaded onto the outer wall of the adjustment screw 9. Positioning rods 12 are fixedly connected between the inner walls of both sides of the two positioning grooves 11. Positioning sliders 13 are slidably fitted onto the outer walls of both positioning rods 12. Multiple fixed plates 4 and the fixing frame 2 are positioned near the corresponding connecting plates 33. A sliding groove 30 is provided, and a sliding rod 31 is fixedly connected between the front and rear inner walls of multiple sliding grooves 30. A sliding block 32 is slidably fitted onto the outer wall of each sliding rod 31. Each sliding block 32 is fixedly connected to a corresponding connecting plate 33. Adjacent connecting rods 7 are rotatably connected. An adjusting slider 10 is fixedly connected to a second support plate 6. Two positioning sliders 13 are fixedly connected to their respective first support plates 5. Multiple connecting rods 7 form a hinged structure with the fixing frame 2. When the adjusting screw 9 drives the adjusting slider 10 to move, the adjusting slider 10 drives the fixed plate 4 connected to it to translate via the second support plate 6. The movement of the fixed plate 4 is transmitted to other fixed plates 4 via the connecting rods 7, causing all fixed plates 4 to move synchronously and equidistantly. 13 slides on the positioning rod 12 to provide auxiliary support for the fixed plate 4 groups, ensuring their stability during movement. A cylinder 14 is fixedly installed at the upper center of each of the multiple fixed plates 4. The telescopic ends of the multiple cylinders 14 pass through the corresponding fixed plate 4 and are fixedly connected to the lifting seat 15. Positioning telescopic rods 26 are fixedly connected to the front and rear ends of the upper parts of the multiple fixed plates 4. The telescopic ends of the multiple positioning telescopic rods 26 pass through the corresponding fixed plate 4 and are fixedly connected to the corresponding lifting seat 15. The positioning telescopic rods 26 make the lifting process of the lifting seat 15 more stable. A controller 25 and a first motor 24 are fixedly installed on the front and rear sides of one side of the processing table 1, respectively. A second motor 29 is fixedly installed at the front end of each of the multiple lifting seats 15. Through cutting... Component 3, with its multiple components working together, including the fixed plate 4, support plate, and connecting rod 7, forms a linkage structure. Driven by a lead screw, cylinder 14, and motor, it enables the position adjustment, lifting, and moving cutting action of the cutting blade 19. The spacing between multiple cutting blades 19 can be quickly adjusted, allowing for simultaneous multi-position cutting. Compared to traditional single-blade cutting equipment, this significantly improves production efficiency. Each of the lower center of multiple lifting seats 15 has a moving groove 16. Moving lead screws 17 are rotatably connected between the front and rear inner walls of each moving groove 16. Moving sliders 18 are threaded onto the outer walls of each moving lead screw 17. Each moving slider 18 slides within its corresponding moving groove 16, and a cutting blade 19 is fixedly connected to the lower end of each moving slider 18.The output ends of multiple second motors 29 all pass through the corresponding lifting base 15 and are fixedly connected to the corresponding moving lead screw 17. When the motor starts, it drives the lead screw to rotate, which in turn moves the cutting blade 19 via the provided moving slider 18, thereby realizing the cutting action of the non-woven fabric.

[0037] Multiple positioning sleeves 20 are fixedly connected to both sides of the lower end of multiple lifting seats 15. Movable columns 21 are slidably arranged inside each positioning sleeve 20. Positioning pressure plates 22 are fixedly connected to the lower ends of multiple movable columns 21 located on the same side. Telescopic springs 23 are fixedly connected between the inner walls of the opposite ends of the multiple movable columns 21 and the corresponding positioning sleeves 20. When the cylinder 14 drives the lifting seat 15 to descend, the positioning sleeves 20 move downwards synchronously with the lifting seat 15. Since the positioning pressure plates 22 at the lower ends of the movable columns 21 contact the non-woven fabric surface first, the movable columns 21 slide upwards relative to the positioning sleeves 20 under the action of material resistance, compressing the internal telescopic springs 23. The generated elastic force is evenly applied to the surface of the nonwoven fabric through the positioning pressure plate 22, forming a stable pre-tightening force to pre-press and fix the nonwoven fabric, which can effectively prevent the material from slipping or wrinkling due to the lateral force generated by the blade cutting during the cutting process. The output end of the first motor 24 passes through the processing table 1 and is fixedly connected to the adjusting screw 9. The first motor 24, multiple cylinders 14 and multiple second motors 29 are all electrically connected to the controller 25. The controller 25 acts as the command center and outputs electrical signals to control the start, stop, speed and extension of the first motor 24 (adjusting the position of the cutting component 3), cylinder 14 (driving the lifting), and second motor 29 (driving the cutting blade 19 to move).

[0038] Working principle: In use, the operator first places the non-woven fabric on the processing table 1, aligning its end with the end positioning plate 28 to complete the initial positioning of the material. After starting the equipment, the controller 25 sends a command to the first motor 24 according to the preset parameters, driving the adjusting screw 9 to rotate. Through the connection between the adjusting slider 10 and the second support plate 6, the fixed plate 4 connected to it is moved horizontally. Since the adjacent connecting rods 7 are rotated and connected, a parallelogram linkage mechanism is formed. The movement of the fixed plate 4 is synchronously transmitted to other fixed plates 4 through the connecting rods 7, so that all fixed plates 4 slide synchronously and equidistantly along the positioning rod 12, quickly completing the spacing adjustment of multiple cutting blades 19. Subsequently, the controller 25 controls the cylinder 14 to move, driving the lifting seat 15 to descend. During this process, the positioning pressure plate 22 first contacts the surface of the non-woven fabric, and the movable column 21 compresses the telescopic spring 23 under the action of material resistance, using the spring force to form a stable pre-tightening force on the non-woven fabric to prevent the material from slipping during cutting. Once the positioning plate 22 is fixed in place, the cylinder 14 continues to push the lifting seat 15 down, causing the cutting blade 19 to cut into the non-woven fabric and contact the industrial rubber plate 27 on the processing table 1. At this time, the controller 25 triggers the second motor 29 to start, driving the moving lead screw 17 to rotate. The rotating motion is converted into linear motion through the moving slider 18, driving the cutting blade 19 to move laterally along the moving groove 16 to complete the cutting of the non-woven fabric and achieve one-time multi-position cutting.
