Description

Technical Field

[0001] This invention relates to the field of cutting device technology, and more particularly to a cutting device for textile machine parts. Background Technology

[0002] Textile machines, also known as spinning machines, looms, or cotton spinning machines, are a general term for various mechanical equipment in the textile industry that processes natural or chemical fibers into yarn and then weaves them into fabric. Tracing its development, ancient textile machines were mostly simple devices driven by human or animal power. With the continuous innovation of industrial technology, textile machines have undergone a leap from mechanization to intelligence, gradually evolving from traditional mechanical looms to modern CNC automatic looms that integrate electronic and computer technologies. This has not only greatly improved production efficiency and product quality but also achieved a high degree of automation and precision control, making it an indispensable core equipment in the modern textile industry.

[0003] During the production process of textile machines, various parts usually need to be cut to facilitate the production and assembly of the textile machine. Due to the different sizes and shapes, the production and processing of parts need to be cut according to different requirements. Existing cutting tools can generally only cut in a straight line in the up-down or left-right direction, and cannot cut parts at an offset angle. The cutting direction of the cutting tool cannot be adjusted. The only way is for the worker to hold the part by hand and align the part with the cutting tool to cut it. However, this is very tiring and not conducive to long-term work. In addition, the part is prone to shaking when cutting by hand, which affects the cutting effect of the tool and results in low work efficiency.

[0004] In actual production, in order to improve processing efficiency, mechanical equipment is usually used to drive the blades to rotate and cooperate with the conveyor belt for batch cutting. However, mechanical cutting can easily cause material to be squeezed, stretched, curled and deformed, resulting in cutting size deviation. In addition, it is necessary to stop the machine regularly to replace the blades or sharpen them, which reduces the production efficiency of the equipment. Summary of the Invention

[0005] The purpose of this invention is to solve the shortcomings of existing technologies, such as the easy extrusion, stretching, curling and deformation of materials when using mechanical blades for cutting, resulting in deviations in cutting dimensions, the need for periodic machine shutdowns to replace blades or sharpen them, and the reduction of equipment production efficiency. Therefore, this invention proposes a cutting device for textile machine parts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a cutting device for textile machine parts, including a support frame, a movable structure on the support frame, a mounting frame on the movable structure, a cutting mechanism on the mounting frame, a conveying unit on the support frame, and a clamping mechanism and a lifting structure that are linked to the cutting mechanism on the conveying unit.

[0007] Furthermore, the cutting mechanism includes a lifting structure, a lateral movement structure, and a cutting module, and the clamping mechanism and the lifting structure are poweredly connected to the lifting structure.

[0008] Furthermore, the lifting structure includes a fixed plate, a stepper motor is mounted on the mounting bracket, a first lead screw is poweredly connected to the shaft end of the stepper motor, and a first nut seat that is threadedly connected to the first lead screw is fixedly provided on the fixed plate.

[0009] Furthermore, a slider is mounted on the fixed plate, a slide rail corresponding to the slider is fixedly provided on the mounting bracket, and a connecting rod that is rotatably connected to the clamping mechanism is rotatably connected to the slider. The clamping mechanism includes two clamping blocks arranged opposite each other, each clamping block having an installation groove, and a support frame that cooperates with the installation groove is fixedly installed on the mounting frame.

[0010] Furthermore, the transverse structure includes a drive motor mounted on the fixed plate, the output shaft of the drive motor is poweredly connected to a second lead screw, the cutting module is provided with a second nut seat threadedly connected to the second lead screw, a guide block is fixedly provided on the cutting module, and a guide rail that cooperates with the guide block is fixedly provided on the fixed plate.

[0011] Furthermore, a scissor lifting mechanism poweredly connected to the clamping block is installed inside the support frame. A drive block and a transmission block poweredly connected to the scissor lifting mechanism are provided on the support frame. The drive block is rotatably connected to the connecting rod. A reset plate is fixedly provided on the clamping block. The reset plate is connected to the mounting frame by a spring.

[0012] Furthermore, the lifting structure includes a connecting frame fixedly connected to two support frames. A guide tube is fixedly installed on the connecting frame, and a guide column is inserted into the guide tube. A lifting part is provided on the guide column. The lifting part includes a base plate, and a support column is fixedly installed on the base plate. A slot is opened at the top of the support column, and a support plate is provided on the base plate. A connecting column that is inserted into the slot is fixedly installed at the lower end of the support plate.

[0013] Furthermore, the guide post is a threaded post, and a threaded sleeve is threadedly connected to the guide post. The threaded sleeve is poweredly connected to the transmission block through a transmission rod, and a telescopic component is provided on the transmission rod.

[0014] Furthermore, the cutting module includes a base plate disposed on a transverse structure, a mounting plate disposed on the base plate, a laser cutting head disposed on the mounting plate, a cooling fan disposed below the mounting plate, the mounting plate being rotatably connected to the base plate, and a linear motor rotatably disposed on the base plate and rotatably connected to the mounting plate.

[0015] Furthermore, the movable structure includes a screw mounted on a support frame, a support block threadedly connected to the screw on the mounting frame, a guide rod movably inserted into the support block on the support frame, and a servo motor poweredly connected to the screw fixedly mounted on the support frame.

[0016] The textile machine parts cutting device proposed in this invention has the following advantages: In this invention, the automation level and processing efficiency of the device are improved by linking the cutting mechanism with the clamping mechanism and the lifting structure. The fixed plate is raised and lowered by the screw drive, and then the clamping mechanism is driven to automatically clamp and release the material by mechanical transmission components such as connecting rods, scissor lifting mechanism and transmission rod. At the same time, the lifting structure is driven to perform synchronous lifting and adjustment to prevent the high temperature generated by cutting from damaging the conveying unit. On the other hand, the synchronization of the actions is achieved, ensuring that the clamps automatically lock and the lifting mechanism automatically aligns when the cutting head descends, eliminating the error of manual cooperation and improving the continuity of textile machine parts processing and production safety. Secondly, in this invention, the lifting and lateral movement structures of the laser cutting head both adopt a precision transmission method using a motor in conjunction with a lead screw and guide rail, ensuring high precision and stability of the laser cutting head's movement in space and effectively avoiding cutting path deviation. The cutting module is equipped with a cooling fan to quickly reduce the workpiece temperature, effectively avoiding the risk of the workpiece being burned by excessively high temperature after cutting. The linear motor drives the cutting head angle adjustment, enabling the device to flexibly cope with the cutting needs of complex curved surfaces or inclined edges. Attached Figure Description

[0019] 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.

[0020] Reference Figures 1-11 A textile machine parts cutting device includes a support frame 1, a movable structure 2 on the support frame 1, an mounting frame 3 on the movable structure 2, a cutting mechanism 4 on the mounting frame 3, a conveying unit 5 on the support frame 1, and a clamping mechanism 6 and a lifting structure 7 that are linked to the cutting mechanism 4 on the conveying unit 5.

[0021] In this invention, a cutting system is constructed by setting up a support frame 1, a movable structure 2, a mounting frame 3, a cutting mechanism 4, a conveying unit 5, and a clamping mechanism 6 and a lifting structure 7 that are linked with the cutting mechanism 4. Through the linkage design of the cutting mechanism 4, the clamping mechanism 6, and the lifting structure 7, the mechanical transmission components drive the clamping mechanism 6 to automatically clamp and release the material, while simultaneously driving the lifting structure 7 to perform synchronous lifting and lowering adjustments. During cutting, the workpiece is lifted up, effectively preventing the high temperature generated during cutting from damaging the conveying unit 5 below. On the other hand, this linkage design achieves synchronous action, ensuring that the clamp automatically locks and the lifting mechanism automatically aligns when the cutting head descends.

[0022] Reference Figures 1-3 Furthermore, in this embodiment, the cutting mechanism 4 includes a lifting structure 41, a lateral movement structure 42, and a cutting module 43. The clamping mechanism 6 and the lifting structure 7 are poweredly connected to the lifting structure 41. By dividing the cutting mechanism 4 into a lifting structure 41, a lateral movement structure 42, and a cutting module 43, and setting the clamping mechanism 6 and the lifting structure 7 to be poweredly connected to the lifting structure 41, the lifting structure 41 serves as the core power source, simultaneously driving the cutting module 43 to feed, the clamping mechanism 6 to clamp, and the lifting structure 7 to lift. By using a single power source to drive multiple coordinated actions, the control system is simplified, equipment costs are reduced, and the synchronization of each action is ensured.

[0023] Reference Figures 2-3 Specifically, in this embodiment, the lifting structure 41 includes a fixed plate 411, a stepper motor 412 is mounted on the mounting frame 3, and a first lead screw 413 is poweredly connected to the shaft end of the stepper motor 412. The first lead screw 413 is rotatably mounted on the mounting frame 3, and both the shaft end of the stepper motor 412 and the first lead screw 413 are provided with synchronous pulleys. The two synchronous pulleys are connected by a synchronous belt. A first nut seat 414 is fixedly provided on the fixed plate 411 and threadedly connected to the first lead screw 413. The rotation angle is controlled by the stepper motor 412, thereby controlling the descent height of the cutting head to adapt to the cutting requirements of workpieces of different thicknesses. At the same time, the first lead screw 413 drives the rotational motion into linear motion, outputting a large thrust, which can stably drive the subsequent clamping and lifting components.

[0024] Reference Figure 2 , Figure 3 and Figure 4Furthermore, in this embodiment, a slider 415 is installed on the fixed plate 411, and a slide rail 416 corresponding to the slider 415 is fixedly provided on the mounting frame 3. A connecting rod 417 that is rotatably connected to the clamping mechanism 6 is rotatably connected to the slider 415. By installing the slider 415 on the fixed plate 411 and providing a corresponding slide rail 416 on the mounting frame 3, the fixed plate 411 is prevented from deflecting or shaking during the lifting process, thereby improving the stability of the cutting. Reference Figure 2 , Figure 5 and Figure 6 The clamping mechanism 6 includes two clamping blocks 61 arranged opposite to each other. The clamping blocks 61 are provided with mounting grooves. The mounting frame 3 is fixedly provided with a support frame 62 that cooperates with the mounting grooves. The clamping mechanism 6 is powered by a connecting rod 417, which converts the vertical lifting motion of the fixed plate 411 into a force that drives the clamping mechanism 6 to move.

[0025] Reference Figure 2 Specifically, in this embodiment, the transverse structure 42 includes a drive motor 421 mounted on the fixed plate 411. The output shaft of the drive motor 421 is poweredly connected to a second lead screw 422. Synchronous pulleys are mounted on both the shaft end of the drive motor 421 and the second lead screw 422. The two synchronous pulleys are connected by a synchronous belt. The cutting module 43 is provided with a second nut seat 423 threadedly connected to the second lead screw 422. A guide block 424 is fixedly mounted on the cutting module 43. A guide rail 425 that cooperates with the guide block 424 is fixedly mounted on the fixed plate 411. The transverse structure 42 uses the drive motor 421 in conjunction with the second lead screw 422, the second nut seat 423, and the cooperation between the guide block 424 and the guide rail 425 to realize the horizontal movement of the cutting module 43.

[0026] Reference Figure 5 and Figure 6 It should be noted that, in this embodiment, a scissor lift mechanism 63, which is poweredly connected to the clamping block 61, is installed inside the support frame 62. A drive block 64 and a transmission block 65, which are poweredly connected to the scissor lift mechanism 63, are provided on the support frame 62. The drive block 64 is rotatably connected to the connecting rod 417. A reset plate 66 is fixedly provided on the clamping block 61. The reset plate 66 is connected to the mounting bracket 3 by a spring 67. The drive block 64 is pushed by the connecting rod 417, which in turn drives the scissor lift mechanism 63 to move the clamping block 61, thereby achieving the clamping and fixing of the workpiece. At the same time, by setting the reset plate 66 and the spring 67, the elastic force of the spring 67 is used to assist the reset and release of the clamping block 61.

[0027] Reference Figures 8-11Furthermore, in this embodiment, the lifting structure 7 includes a connecting frame 71 fixedly connected to two support frames 62. A guide tube 72 is fixedly installed on the connecting frame 71, and a guide post 73 is inserted into the guide tube 72. A lifting part 74 is provided on the guide post 73. The lifting part 74 includes a base plate 741, and a support post 742 is fixedly installed on the base plate 741. A slot is opened at the top of the support post 742. A support plate 743 is provided on the base plate 741, and a connecting post inserted into the slot is fixedly installed at the lower end of the support plate 743. The lifting part 74 adopts a structural design in which the base plate 741, the support post 742 and the support plate 743 are inserted into each other, realizing quick disassembly and quick assembly of the support plate 743. The corresponding support plate 743 can be quickly replaced according to different sizes or shapes of textile machine parts, and it is also easy to replace the support plate 743 after it is worn.

[0028] Reference Figure 11 Specifically, in this embodiment, the guide post 73 is a threaded post, and a threaded sleeve 75 is threadedly connected to the guide post 73. The threaded sleeve 75 is poweredly connected to the transmission block 65 through a transmission rod 76. A telescopic component 77 is provided on the transmission rod 76. By designing the guide post 73 as a threaded post and connecting it with the threaded sleeve 75, the transmission rod 76, and the transmission block 65, when the clamping mechanism 6 is activated, the transmission block 65 moves, driving the transmission rod 76, which in turn drives the threaded sleeve 75 to rotate. This causes the guide post 73 to lift the lifting part 74, thereby converting the horizontal driving force of the clamping mechanism 6 into the vertical lifting force of the lifting structure 7. This achieves synchronous clamping and lifting, effectively isolates cutting heat, and protects the conveying unit 5.

[0029] Reference Figure 2 and Figure 4 In detail, in this embodiment, the cutting module 43 includes a base plate 431 disposed on the transverse structure 42, a mounting plate 432 disposed on the base plate 431, a laser cutting head 433 disposed on the mounting plate 432, and a cooling fan 434 disposed below the mounting plate 432. The mounting plate 432 is rotatably connected to the base plate 431. A linear motor 435 is rotatably disposed on the base plate 431 and rotatably connected to the mounting plate 432. The cutting module 43 is equipped with a cooling fan 434, which can quickly cool the cutting area, effectively reduce the workpiece temperature, and avoid the hidden danger of the workpiece being burned by excessively high temperature after cutting. In addition, by driving the mounting plate 432 to rotate relative to the base plate 431 through the linear motor 435, the angle of the laser cutting head 433 is automatically adjusted, so that the device can flexibly cope with the cutting needs of complex curved surfaces, bevels or chamfers on textile machine parts, and increase the processing range of the device.

[0030] Reference Figure 1More specifically, in this embodiment, the movable structure 2 includes a screw 21 disposed on the support frame 1, a support block 22 that is threadedly connected to the screw 21 is disposed on the mounting frame 3, a guide rod 23 is also disposed on the support frame 1, the guide rod 23 is movably inserted into the support block 22, and a servo motor 24 that is power-connected to the screw 21 is fixedly disposed on the support frame 1.

[0031] Working method: First, the equipment is started by an external control device. The textile machine parts to be processed are placed on the conveying unit 5. The conveying unit 5 transports the parts to the preset processing position below the cutting mechanism 4. Then, the servo motor 24 of the moving structure 2 drives the screw 21 to rotate, which drives the support block 22 threadedly connected to it to move along the guide rod 23, thereby adjusting the position of the mounting frame 3 and the cutting mechanism 4 in the horizontal direction to achieve coarse positioning of the parts.

[0032] Specifically, when cutting the parts: Stepper motor 412 drives the first lead screw 413 to rotate, and drives the fixing plate 411 to descend smoothly along the slide rail 416 through the first nut seat 414. The descent of the fixing plate 411 causes the cutting module 43 to move down as a whole and approach the workpiece. At the same time, the clamping mechanism 6 and the lifting structure 7 move synchronously through mechanical linkage. Simultaneously, as the fixed plate 411 descends, the connecting rod 417 rotatably connected to it moves downward and deflects at an angle, pushing the drive block 64 to move. The drive block 64 drives the scissor lifting mechanism 63 to unfold, pushing the two clamping blocks 61 to move relative to each other, thereby firmly clamping the textile machine parts. At this time, the reset plate 66 stretches the spring 67, accumulating reset force; At the same time as the clamping action occurs, the transmission block 65 moves with the scissor lifting mechanism 63, and pulls the threaded sleeve 75 through the transmission rod 76. Since the guide column 73 is a threaded column, the threaded sleeve 75 rotates under the action of tension, thereby driving the guide column 73 to rise axially, driving the lifting part 74 to move upward, and the support plate 743 lifts the accessory, separating it from the conveying unit 5, to prevent the conveying unit 5 from being burned by the high temperature of subsequent cutting. In practice, the drive motor 421 drives the second lead screw 422 to rotate, and the second nut seat 423 drives the base plate 431 to move laterally along the guide rail 425, so as to realize the horizontal movement of the laser cutting head 433. If the cutting path includes a bevel or a specific angle, the linear motor 435 pushes the mounting plate 432 to rotate relative to the base plate 431, and adjusts the angle of the laser cutting head 433 to adapt to complex cutting requirements. During the laser cutting head 433 emitting laser to cut, the cooling fan 434 works continuously to blow cold air into the cutting area to accelerate the cooling of the cut, reduce the heat-affected zone and lower the temperature of the workpiece.

[0033] It should be noted that after the cutting is completed: The stepper motor 412 in the lifting structure 41 reverses, driving the fixed plate 411 to rise and reset. Under the elastic force of the spring 67, the clamping mechanism 6 drives the clamping block 61 to move in the opposite direction through the reset plate 66. At the same time, the lifting structure 7 descends under the action of the reverse movement of the linkage mechanism, placing the processed parts back onto the conveying unit 5. Finally, the conveying unit 5 moves the finished product out of the processing area to achieve cyclic processing.

[0034] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
