Description

Technical Field

[0001] This utility model relates to the field of garment production technology, and in particular to a cutting device for polyester fiber garment production. Background Technology

[0002] Cutting devices for polyester fiber garment production refer to specialized mechanical equipment or tool combinations used in the manufacturing process of polyester fiber garments to precisely cut and trim polyester fiber fabrics to form garment components that meet design requirements. Fabric cutting is one of the key processes in the production of polyester fiber garments, directly affecting the quality of the garments and production efficiency.

[0003] A search revealed Chinese Patent Publication No. CN213203583U, which discloses a cutting device for polyester fiber garment production. The device includes a worktable, a winding mechanism, a transmission mechanism, and a cutting mechanism fixedly mounted on the worktable. The winding mechanism is fixedly mounted at one end of the worktable, and mounting frames are symmetrically arranged in the middle of the worktable. The transmission mechanism includes multiple sets of transmission wheel mechanisms fixedly mounted on the mounting frames. Each transmission wheel mechanism includes two transmission wheel bodies arranged vertically. An ironing device is also provided on the side of the mounting frame. A cutting platform is fixedly mounted at the end of the mounting frame away from the winding mechanism. The cutting mechanism includes a first electric cylinder. The present invention provides a cutting device for polyester fiber garment production, which includes a cutting blade and a gantry frame fixedly installed on the cutting platform near the mounting frame. The first electric cylinder is fixedly installed on the gantry frame, and the cutting blade is fixedly connected to the output end of the first electric cylinder. The cutting device has a good cutting effect. When using existing cutting devices, the operator needs to push the cutting blade with one hand and press the fabric with the other hand to prevent displacement, which easily causes fatigue. The pushing hand continuously controls the direction and speed, resulting in soreness and stiffness in the hand and arm; the pressing hand exerts force for a long time, causing numbness and soreness in the wrist. At the same time, the posture of bending over and stretching the arm will increase the burden on the shoulder, neck and waist. Under long-term operation, fatigue spreads, reduces efficiency, and easily causes accidents. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a cutting device for polyester fiber garment production, which aims to improve the existing technology that requires manual pushing of the machine body and pressing of the fabric to prevent the fabric from moving with the cutting blade, and the operator is prone to fatigue after long-term use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cutting device for polyester fiber garment production, comprising an outer machine, a positioning mechanism fixedly connected to the bottom of the outer wall of the outer machine for pressing the fabric, a cutting mechanism fixedly connected to the middle of the inner wall of the outer machine for quickly cutting cotton garments, and a pressing mechanism fixedly connected to the front side of the outer wall of the outer machine; the positioning mechanism includes a fixing clamp fixedly connected to the bottom of the outer wall of the outer machine, a connecting frame one fixedly connected to the top of the outer wall of the fixing clamp, a connecting frame two rotatably connected to the left side of the inner wall of the connecting frame one, and counterweight plates rotatably connected to both the connecting frame two and the outer wall of the connecting frame one on the side away from the outer wall of the connecting frame one; multiple counterweight blocks fixedly connected to the middle of the inner wall of the counterweight plate, and an adjustment component rotatably connected to the top of the outer wall of the connecting frame one.

[0006] Through the above technical solution: the positioning mechanism of the polyester fiber garment cutting device is responsible for stabilizing the fabric, providing a stable operating foundation for the cutting mechanism. Its operation relies on the coordinated movement of various components. The fixing clamp connects the positioning mechanism to the external machine, ensuring structural stability. Connecting frame one and connecting frame two form an openable frame to adapt to different fabric sizes. The counterweight plate and counterweight block initially fix the fabric by weight, reducing cutting displacement. The adjusting components enhance the flexibility and adaptability of the positioning mechanism.

[0007] As a further description of the above technical solution:

[0008] The adjustment assembly includes two telescopic columns, which are rotatably connected to the left and right sides of the inner wall of the connecting frame. A rebound frame is rotatably connected to the top of the outer wall of the right telescopic column, and a fixed frame is rotatably connected to the left side of the inner wall of the rebound frame. The fixed frame is rotatably connected to the left side of the inner wall of the counterweight plate.

[0009] The above technical solution involves two telescopic columns installed on the inner wall of the connecting frame, which can be rotated to adjust the angle. The top of the right telescopic column is connected to the rebound frame, which works in conjunction with the fixed frame to facilitate adjustment of the position and angle according to the characteristics of the fabric. The counterweight plate, through the elastic structure of the rebound frame, ensures the stability of the fabric and prevents damage. The positioning mechanism, through the weight and adjustability of the counterweight plate, achieves precise positioning of the fabric and improves cutting efficiency.

[0010] As a further description of the above technical solution:

[0011] The cutting mechanism includes a limiting plate, which is fixedly connected to the front side of the inner wall of the outdoor unit. A cutter is slidably connected to the middle of the inner wall of the limiting plate. A connecting rod is fixedly connected to the top of the outer wall of the cutter. A rotating component is fixedly connected to the top of the outer wall of the connecting rod.

[0012] The above technical solution converts the power of the motor into the precise cutting action of the cutter. The limiting plate, as a supporting component, is fixed to the front side of the inner wall of the outer unit to guide the cutter and ensure the stability of the cutting direction.

[0013] As a further description of the above technical solution:

[0014] The rotating assembly includes a motor, which is fixedly connected to the rear side of the inner wall of the outdoor unit. The output end of the motor is fixedly connected to a rotating shaft. Adjusting brackets are rotatably connected to the front and rear sides of the inner wall of the rotating shaft. Connecting columns are rotatably connected to the inner walls of the two adjusting brackets. The connecting columns are fixedly connected to the top of the outer wall of the connecting rod.

[0015] Through the above technical solution: when the motor starts, the rotating shaft drives the adjusting frame, connecting column and connecting rod, so that the cutter slides back and forth on the inner wall of the limiting plate. The adjusting frame adjusts the angle to control the cutter stroke and force. When the motor is running, the cutter slides at high frequency under the constraint of the limiting plate, generating shearing force to cut the material. The structure of the external unit ensures the stable operation of the cutting mechanism and achieves efficient and precise cutting.

[0016] As a further description of the above technical solution:

[0017] The pressing mechanism includes a fixed plate, which is fixedly connected to the front side of the outer wall of the outdoor unit. A pressure rod is slidably connected to the middle of the inner wall of the fixed plate. A base is provided at the bottom of the outer wall of the pressure rod. A wear-resistant component is fixedly connected to one side of the outer wall of the fixed plate.

[0018] Through the above technical solution: the operation of the pressing mechanism relies on the synergistic effect of the components, among which the fixed plate serves as the main support, connected to the front side of the outdoor unit, providing the installation base for the mechanism. During operation, the pressure rod slides smoothly in the inner wall of the fixed plate, transmitting pressure to the base and the pressure foot.

[0019] As a further description of the above technical solution:

[0020] The wear-resistant component includes a spring, which is fixedly connected to the middle of the outer wall of the pressure rod. A pressure foot is rotatably connected to the bottom end of the outer wall of the pressure rod, and ball bearings are rotatably connected to the four corners of the bottom of the base.

[0021] Through the above technical solution: the spring of the wear-resistant component is located in the middle of the pressure bar for buffering and reset. When pressed down, the spring is compressed to absorb the impact force and prevent damage; the presser foot at the bottom of the pressure bar can adjust the angle with the fabric surface to ensure uniform pressing; the ball bearings at the bottom of the base reduce the movement resistance, allowing the base to roll flexibly and reduce friction loss.

[0022] As a further description of the above technical solution:

[0023] A handle is fixedly connected to the top of the outer wall of the outdoor unit, and screws are threaded onto the left and right sides of the outer wall of the handle.

[0024] The above technical solution makes it easier for operators to carry, hold, and control the outdoor unit with the handles provided.

[0025] As a further description of the above technical solution:

[0026] A handle is fixedly connected to the bottom rear side of the outdoor unit, and heat dissipation holes are opened around the outer wall of the outdoor unit.

[0027] The above technical solution enables the grip to facilitate operation, while the heat dissipation holes ensure that the equipment can effectively dissipate heat during long-term operation, thereby maintaining its stable performance.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, during cutting, the counterweight can replace the human hand to press down on the fabric to position the fabric. The fixing clamp securely connects the positioning mechanism to the bottom of the outer machine. The rotating structure of connecting frame one and connecting frame two can adapt to different fabric sizes. The counterweight in the counterweight plate initially presses down on the fabric by gravity to prevent displacement. The adjustment component enhances the adaptability of the device: the telescopic column can be adjusted in length, and the linkage between the rebound frame and the fixing frame changes the angle of the counterweight plate to make it fit the fabric surface. The elastic buffer of the rebound frame avoids damage to the fabric due to pressure, ensures the stability of the fabric during cutting, and improves cutting accuracy and efficiency.

[0030] 2. In this utility model, the cutting mechanism achieves precise cutting through motor drive. The limiting plate is fixed to the front side of the inner wall of the outer unit to guide the cutter. After the motor starts, the rotating shaft drives the adjustment frame to move. The power is transmitted through the connecting column and connecting rod, causing the cutter to slide back and forth along the limiting plate. The adjustment frame can flexibly change the angle and precisely control the cutter's stroke and force. When the motor runs continuously, the high-frequency sliding of the cutter generates shearing force to cut the material. The structure of the outer unit ensures stable and efficient cutting.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a cutting device for polyester fiber garment production, comprising an outer machine 1, a positioning mechanism 2 fixedly connected to the bottom of the outer wall of the outer machine 1 for pressing the fabric, a cutting mechanism 3 fixedly connected to the middle of the inner wall of the outer machine 1 for quick cutting of cotton garments, and a pressing mechanism 4 fixedly connected to the front side of the outer wall of the outer machine 1; the positioning mechanism 2 includes a fixing clamp 201 fixedly connected to the bottom of the outer wall of the outer machine 1, a connecting frame 1 202 fixedly connected to the top of the outer wall of the fixing clamp 201, and a connecting frame 203 rotatably connected to the left side of the inner wall of the connecting frame 1 202. Counterweight plates 204 are rotatably connected to the outer walls of frame 203 and connecting frame 1, which are on opposite sides. Multiple counterweight blocks 205 are fixedly connected to the middle of the inner wall of counterweight plate 204. An adjustment assembly 206 is rotatably connected to the top of the outer wall of connecting frame 1, which includes two telescopic columns 2061. The two telescopic columns 2061 are rotatably connected to the left and right sides of the inner wall of connecting frame 1, which are connected to the left and right sides of the inner wall of connecting frame 1, which are connected to the top of the outer wall of the right telescopic column 2061. A rebound frame 2063 is rotatably connected to the left side of the inner wall of the rebound frame 2063. A fixed frame 2062 is rotatably connected to the left side of the inner wall of counterweight plate 204.

[0040] Specifically, in the polyester fiber garment cutting device, the main function of the positioning mechanism 2 is to stabilize the fabric and provide a solid working foundation for the cutting mechanism 3. The positioning mechanism 2 completes its work through the coordinated movement of its components. The fixing clamp 201 connects the positioning mechanism 2 to the external machine 1 to ensure structural stability. The connecting frame 1 202 and the connecting frame 203 form an openable frame to adapt to different fabric sizes. The counterweight plate 204 provides initial downward pressure and fixing force through the counterweight block 205 to reduce fabric displacement during cutting. The adjusting component 206 enhances the flexibility of the positioning mechanism 2. The combination of the telescopic column 2061 and the spring frame 2063 can adjust the angle to adapt to the fabric characteristics and ensure fabric stability. The positioning mechanism 2 ensures accurate and efficient cutting through these mechanisms.

[0041] Reference Figure 1 , Figure 2 and Figure 5 The cutting mechanism 3 includes a limiting plate 301, which is fixedly connected to the front side of the inner wall of the outdoor unit 1. A cutter 302 is slidably connected to the middle of the inner wall of the limiting plate 301. A connecting rod 303 is fixedly connected to the top of the outer wall of the cutter 302. A rotating assembly 304 is fixedly connected to the top of the outer wall of the connecting rod 303. The rotating assembly 304 includes a motor 3041, which is fixedly connected to the rear side of the inner wall of the outdoor unit 1. A rotating shaft 3042 is fixedly connected to the output end of the motor 3041. An adjusting frame 3043 is rotatably connected to the front and rear sides of the middle of the inner wall of the rotating shaft 3042. A connecting column 3044 is rotatably connected to the middle of the inner wall of the two adjusting frames 3043. The connecting column 3044 is fixedly connected to the top of the outer wall of the connecting rod 303.

[0042] Specifically, the core function of the cutting mechanism 3 is to convert the power of the motor 3041 into the precise cutting action of the cutter 302. The limiting plate 301, as a supporting component, is fixed to the front side of the inner wall of the outer unit 1 to provide guidance for the cutter 302 and ensure the stability of the cutting direction. After the motor 3041 starts, the rotating shaft 3042 rotates, driving the adjusting frame 3043, the connecting column 3044 and the connecting rod 303, ultimately causing the cutter 302 to slide back and forth along the inner wall of the limiting plate 301. The adjusting frame 3043 can adjust the angle to control the stroke and force of the cutter 302. When the motor 3041 runs continuously, the cutter 302 slides at high frequency under the constraint of the limiting plate 301, generating shearing force to cut the material. The structural design of the outer unit 1 ensures the stable operation of the cutting mechanism 3 and achieves efficient and precise cutting.

[0043] Reference Figure 1 , Figure 2 and Figure 3 The pressing mechanism 4 includes a fixed plate 401, which is fixedly connected to the front side of the outer wall of the outdoor unit 1. A pressure rod 402 is slidably connected to the middle of the inner wall of the fixed plate 401. A base 403 is provided at the bottom of the outer wall of the pressure rod 402. A wear-resistant component 404 is fixedly connected to one side of the outer wall of the fixed plate 401. The wear-resistant component 404 includes a spring 4041, which is fixedly connected to the middle of the outer wall of the pressure rod 402. A pressure foot 4042 is rotatably connected to the bottom of the outer wall of the pressure rod 402. Ball bearings 4043 are rotatably connected to the four corners of the bottom of the base 403. A handle 6 is fixedly connected to the top of the outer wall of the outdoor unit 1. Screws 5 are threadedly connected to the left and right sides of the outer wall of the handle 6. A grip 7 is fixedly connected to the bottom rear side of the outdoor unit 1. Heat dissipation holes 8 are opened around the outer wall of the outdoor unit 1.

[0044] Specifically, the operation of the pressing mechanism 4 relies on the coordinated operation of various components. The fixed plate 401, as the core support component, is firmly connected to the front outer wall of the outdoor unit 1, providing the installation foundation for the entire mechanism. When the operator applies force to the pressure rod 402, the pressure rod 402 can smoothly slide along the middle of the inner wall of the fixed plate 401, transmitting the pressure to the bottom base 403 and the pressure foot 4042. The spring 4041 in the wear-resistant component 404 is sleeved in the middle of the outer wall of the pressure rod 402, playing a buffering and restoring role. When pressed down, the spring 4041 is compressed and contracts, absorbing part of the impact force and avoiding rigid collision damage to the components; after the external force is removed, the spring 4041... The pressure bar 402 automatically rises by restoring its own elasticity and deformation. The pressure foot 4042, which is rotatably connected to the bottom of the pressure bar 402, can flexibly adjust its angle according to the surface undulation when contacting the object being pressed, such as cloth, to ensure uniform pressing and fit. The ball bearings 4043 at the four corners of the bottom of the base 403 reduce the resistance to movement. When pressing operations are required in different positions, the ball bearings 4043 can make the base 403 roll flexibly on the object surface, reducing friction loss. In addition, the handle 6 and grip 7 on the outdoor unit 1 facilitate the operator's handling and control, while the heat dissipation holes 8 ensure effective heat dissipation during long-term operation and maintain stable performance.

[0045] Working Principle: In the cutting device for polyester fiber garment production, the core function of the positioning mechanism 2 is to firmly press the fabric, providing a stable working foundation for the cutting mechanism 3. Its working process relies on the coordinated movement of various components. The fixing clamp 201 serves as the connection hub between the positioning mechanism 2 and the outer machine 1, fixing the entire positioning mechanism 2 to the bottom of the outer wall of the outer machine 1 to ensure structural stability. The connecting frame 1 202 and the connecting frame 203 are rotatably connected to form a flexible opening and closing frame structure. This design allows the positioning mechanism 2 to adapt to fabrics of different sizes and shapes. The counterweight plate 204 is rotatably connected to the connecting frame 1 202 and the connecting frame 203 respectively. Multiple counterweight blocks 205 inside the plate provide initial downward pressure and fixing force to the fabric through their own weight, reducing the displacement of the fabric during the cutting process. The adjusting component 206 further enhances the flexibility and adaptability of the positioning mechanism 2. Two telescopic columns 2061 are rotatably installed on the inner wall of the connecting frame 1 202. On the right side, the top of the telescopic column 2061 is rotatably connected to the rebound frame 2063. Through the rotational cooperation with the fixed frame 2062, the angle can be flexibly adjusted. When it is necessary to position the fabric, the operator can adjust the telescopic length of the telescopic column 2061 according to the thickness and flatness of the fabric, thereby changing the position and angle of the rebound frame 2063 and the fixed frame 2062, causing the counterweight plate 204 to adhere to the surface of the fabric. The elastic structure of the rebound frame 2063 can provide a certain buffer when pressing the fabric, which can ensure that the fabric is pressed tightly and avoid damage to the fabric due to excessive pressure. In this way, the positioning mechanism 2 can stably fix the fabric, ensuring the accuracy and efficiency of the cutting process. The positioning mechanism 2 for pressing the fabric is movably connected to the machine body. The positioning mechanism 2 is a counterweight plate 204 with a certain weight. The counterweight plate 204 is detachably connected to the machine body and its length and width can be adjusted. Its detachable method and size adjustment structure can be expanded by itself.

[0046] The core of the cutting mechanism 3's operation lies in converting the power of the motor 3041 into the precise cutting action of the cutter 302. The limiting plate 301, as a basic support component, is firmly fixed to the front side of the inner wall of the outer unit 1, providing a guide rail for the sliding of the cutter 302 and ensuring the stability of the cutting direction. When the motor 3041 starts, its output shaft 3042 begins to rotate. The adjusting frame 3043, rotatably connected to the front and rear sides of the inner wall of the shaft 3042, moves accordingly. The adjusting frame 3043 is connected to the connecting rod 303 via the connecting column 3044, and the connecting rod 303 is fixed to the cutter 302. Therefore, the rotational movement of the shaft 3042 is controlled by the adjusting frame 3043. The connecting column 3044 and connecting rod 303 ultimately transmit power to the cutter 302, causing the cutter 302 to slide back and forth along the middle of the inner wall of the limiting plate 301. The adjusting frame 3043 can rotate flexibly to change the angle between itself and the rotating shaft 3042 and the connecting column 3044, thereby precisely controlling the sliding stroke and cutting force of the cutter 302. When it is necessary to cut the material, the motor 3041 runs continuously. Under the constraint of the limiting plate 301, the cutter 302 generates a strong shearing force by sliding back and forth at a high frequency, thereby cutting the material. The structural design of the external unit 1 provides a stable operating space for the entire cutting mechanism 3, ensuring that the cutting process is efficient and accurate.
