Description

Technical Field

[0001] This utility model relates to the field of fabric production equipment technology, specifically a cutting device for fabric production. Background Technology

[0002] In the fabric manufacturing industry, cutting is a key processing step, and its efficiency and quality directly affect the final quality of the product and production efficiency.

[0003] Traditional fabric cutting devices have many drawbacks. On the one hand, some devices lack a stable and reliable fabric conveying system, which can easily lead to problems such as fabric shifting and wrinkling during the conveying process. This not only affects the cutting accuracy but also increases the workload of subsequent finishing. Moreover, the low degree of automation of the conveying system requires frequent manual intervention, reducing production efficiency. On the other hand, some devices fail to effectively flatten the fabric before cutting, resulting in wrinkles and unevenness on the fabric surface. This leads to inaccurate fabric dimensions and uneven edges. In addition, the cutting mechanism's movements are not precise and stable enough, which can easily cause cutting deviations or blade jamming, affecting the quality and efficiency of cutting. Therefore, we propose a fabric cutting device for production. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for fabric production to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fabric cutting device includes a worktable. A groove is provided on the left side of the worktable, and a fabric roller is rotatably mounted in the groove. Conveyor rollers are rotatably mounted on the left and right sides of the top of the worktable via mounting frames and rotating shafts. Rubber pads are provided on the conveyor rollers. A fixed frame is also provided on the top of the worktable between the two mounting frames. A lifting plate is slidably mounted on the fixed frame. A plurality of telescopic rods are evenly arranged at the bottom of the lifting plate. A pressing plate is provided at the end of the telescopic arm of the telescopic rod.

[0008] As a further improvement of this utility model: a threaded rod is rotatably provided on the fixed plate, the threaded rod passing through the slider and being threadedly connected to the slider.

[0009] As a further improvement of this utility model: a synchronous pulley is connected to the rotating shaft of the conveying roller by a key, and the left and right synchronous pulleys are connected by a synchronous belt.

[0010] As a further improvement of this utility model: a power motor is provided on the outer wall of the mounting frame on the left side, and the power output shaft of the power motor is connected to the rotating shaft of the conveying roller through a coupling.

[0011] As a further improvement of this utility model: a servo motor is also provided on the side wall of the fixed plate, and the power output shaft of the servo motor is connected to the threaded rod through a coupling.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The device uses a conveyor roller with a rubber pad on the top of the worktable and a synchronous pulley and belt to achieve synchronous rotation of the two conveyor rollers. With the help of a power motor, it can stably and continuously convey the fabric, effectively avoiding fabric deviation and wrinkles. At the same time, a sliding flattening roller is set on the back of the fixed frame. The threaded rod driven by the servo motor drives the slider to move, so that the flattening roller rotates under the meshing action of gears and racks, accurately flattening the fabric and ensuring that the fabric is flat before cutting, which greatly improves the cutting accuracy and quality.

[0014] 2. The lifting plate, which slides on the fixed frame, can drive the cutter up and down under the influence of a hydraulic rod to achieve the cutting action. The telescopic rod and return spring at the bottom of the lifting plate ensure that the pressing plate remains stable after contacting the fabric, guaranteeing the stability of the fabric during the cutting process. At the same time, the cutter can continue to descend to complete the cutting, improving the cutting accuracy. Moreover, the coordinated work of all components results in a high degree of automation, reducing manual intervention, effectively improving cutting efficiency, and reducing production costs.

[0020] Example

[0021] Please see Figures 1-3 In this embodiment of the present invention, a fabric production cutting device includes a workbench 1. A groove is provided on the left side of the workbench 1, and a fabric roller 2 is rotatably disposed in the groove. Under the action of the fabric roller 2, the fabric can be conveyed, thereby ensuring the smooth progress of subsequent cutting work.

[0022] The top left and right sides of the workbench 1 are also equipped with conveyor rollers 3 via mounting brackets and rotating shafts. Rubber pads are installed on the conveyor rollers 3. In actual use, when it is necessary to convey the fabric, the operator puts one end of the fabric under the left conveyor roller 3, and then uses the friction between the conveyor roller 3 and the fabric to convey the fabric. At the same time, the fabric at the other end is received by the right conveyor roller 3, thereby realizing the automated loading and unloading function.

[0023] A synchronous pulley 4 is connected to the rotating shaft of the conveying roller 3 via a key. The two synchronous pulleys 4 are connected by a synchronous belt 6. Under the action of the synchronous pulleys 4 and the synchronous belt 6, the two conveying rollers 3 can rotate synchronously, thereby completing the function of stable and continuous fabric conveying and output. A power motor 5 is installed on the outer wall of the mounting frame on the left side. The power output shaft of the power motor 5 is connected to the rotating shaft of the conveying roller 3 via a coupling. At this time, the power motor 5 can drive the conveying roller 3 to rotate.

[0024] A fixed frame 7 is also provided on the top of the workbench 1 between the two mounting brackets on the left and right. A lifting plate 14 is slidably mounted on the fixed frame 7. Several telescopic rods 15 are evenly arranged at the bottom of the lifting plate 14. A pressing plate 18 is provided at the end of the telescopic arm of the telescopic rod 15. A return spring 16 is also sleeved on the outside of the telescopic rod 15. One end of the return spring 16 is connected to the lifting plate 14, and the other end of the return spring 16 is connected to the pressing plate 18. A cutter 17 is also provided at the bottom of the lifting plate 14. A hydraulic rod 8 is also provided on the fixed frame 7. The telescopic arm is connected to the lifting plate 14. When the fabric needs to be cut, the hydraulic rod 8 drives the lifting plate 14 to move downward. When the pressing plate 18 contacts the fabric, the cutter 17 continues to descend under the action of the telescopic rod 15, thereby cutting the fabric. After the cutting is completed, the hydraulic rod 8 is retracted. In addition, under the action of the return spring 16, the pressing plate 18 returns to its original position, thus ensuring the efficiency of subsequent use. At the same time, under the action of the pressing plate 18, the stability of the fabric is ensured during cutting, thereby ensuring the quality of cutting.

[0025] A sliding rod 10 and a threaded rod 12 are provided on the rear outer wall of the fixed frame 7 via a fixed plate 9. A slider 11 is slidably mounted on the sliding rod 10. The threaded rod 12 passes through the slider 11 and is threadedly connected to the slider 11. A flattening roller 21 is rotatably mounted on the slider 11. A gear 20 is connected to the shaft of the flattening roller 21 via a key. A rack 19 is provided on the front outer wall of the fixed frame 7. The rack 19 meshes with the gear 20. When the fabric needs to be cut, the threaded rod 12 drives the slider 11 to move, thereby causing the flattening roller 21 to rotate under the action of the gear 20 and the rack 19, thus flattening the fabric inside the fixed frame 7 and ensuring the subsequent cutting quality. A servo motor 13 is also provided on the side wall of the fixed plate 9. The power output shaft of the servo motor 13 is connected to the threaded rod 12 via a coupling.

[0026] During operation, the worker feeds one end of the fabric under the left conveyor roller 3 and starts the power motor 5. Its power output shaft drives the left conveyor roller 3 to rotate via a coupling. Since the rotating shafts of the two conveyor rollers 3 are connected by a key with synchronous pulleys 4, and the two synchronous pulleys 4 are connected by a synchronous belt 6, the two conveyor rollers 3 rotate synchronously. The friction between the conveyor rollers 3 and the fabric is used to smoothly and continuously transport the fabric. When the fabric reaches the appropriate position for cutting, the hydraulic rod 8 is activated. Its telescopic arm pushes the lifting plate 14 downwards. The pressing plate 18 at the bottom of the lifting plate 14 first contacts the fabric. Under the action of the telescopic rod 15, the pressing plate 18 stops moving, while the lifting plate 14 continues to descend, driving the cutter 17 to cut the fabric. After cutting, the hydraulic rod 8 retracts, the lifting plate 14 rises, and under the action of the return spring 16, the pressing plate 18 returns to its position. Simultaneously, the cutter 17 also rises with the lifting plate 14, completing one cutting action. Before cutting, to ensure cutting quality, the fabric needs to be flattened. The servo motor 13 is started, and its power output shaft drives the threaded rod 12 to rotate through the coupling. The threaded rod 12 drives the slider 11 to slide on the slide bar 10, and the flattening roller 21 on the slider 11 moves accordingly. At the same time, the gear 20 on the shaft of the flattening roller 21 meshes with the rack 19 on the front outer wall of the fixed frame 7, so that the flattening roller 21 rotates during the movement, flattening the fabric inside the fixed frame 7, ensuring that the fabric is flat before cutting, thereby improving the cutting quality.
