Description
Technical Field
[0001] This utility model relates to the field of raincoat fabric processing technology, and in particular to a raincoat fabric cutting device. Background Technology
[0002] As a key piece of equipment in the raincoat production process, the raincoat fabric cutting device precisely cuts the raincoat fabric to specific sizes and shapes, providing the basic components for subsequent raincoat manufacturing. In the modern raincoat manufacturing industry, with the ever-increasing demands for raincoat quality and production efficiency, the performance and function of this device are receiving increasing attention. In actual production, the raincoat fabric cutting device typically involves the following key components:
[0003] 1. Conveying device: responsible for smoothly conveying the raincoat fabric to the cutting area. Common conveying methods include roller conveyor and belt conveyor. It is required to ensure that the fabric conveying speed is uniform and stable.
[0004] 2. Cutting device: includes various types of blades, such as rotary blades and straight blades. The sharpness and cutting accuracy of the blades directly affect the cutting quality.
[0005] 3. Positioning device: The cutting position of the fabric is determined by the use of rulers, sensors and other equipment to ensure the accuracy of the cutting size.
[0006] Currently, to meet the demands of raincoat production, manufacturers employ various types of raincoat fabric cutting equipment. Some manufacturers use manually operated cutting devices, which are simple in structure and low in cost, but require highly skilled operators and have low production efficiency. Other manufacturers use semi-automatic cutting devices, which improve production efficiency to some extent, but still have shortcomings in terms of precise fabric positioning and automation. Some large enterprises have introduced fully automatic cutting devices, which have a high level of automation, but still face some challenges in handling different fabric characteristics and complex cutting requirements.
[0007] However, the above-described implementation methods still have the following problems. Regarding fabric tension control, many devices have fixed adjustment mechanisms, making it impossible to adjust tension according to the fabric's thickness, material, and other characteristics. This leads to wrinkles and loosening of the fabric during transport, affecting cutting accuracy. Regarding fabric anti-shifting, existing devices have fixed anti-shifting plates, which cannot meet the cutting needs of fabrics of different widths. This application proposes a solution to this problem: a vertically adjustable tensioning mechanism and a fabric anti-shifting structure. The vertically adjustable tensioning mechanism can flexibly adjust the tension according to the actual situation of the fabric, ensuring the stability of fabric transport; the fabric anti-shifting structure can effectively prevent fabric shifting during cutting, improving cutting accuracy, reducing defect rates, and enhancing the overall quality and efficiency of raincoat production. Utility Model Content
[0008] To address the shortcomings of existing technologies, this utility model provides a raincoat fabric cutting device that solves the problem that many devices have fixed adjustment mechanisms, making it impossible to adjust the tension according to the thickness, material, and other characteristics of the fabric. This results in wrinkles and loosening of the fabric during the conveying process, affecting the cutting accuracy. In terms of preventing fabric displacement, the existing devices have fixed anti-displacement plates, which cannot meet the cutting needs of fabrics of different widths.
[0009] To achieve the above objectives, this utility model provides the following technical solution:
[0010] A raincoat fabric cutting device includes a frame, a conveying mechanism, and a cutting mechanism. A control panel is provided on the surface of the frame.

A connecting strip is provided inside the frame. A tensioning push rod is movably engaged within the connecting strip. Two return springs for providing pushing force are fixedly connected to the lower surface of the push rod. A drive screw is provided in front of the connecting strip. A rotating rod is threaded between the two supports. Both return springs are fixedly connected to the connecting strip. The push rod is in contact with the fabric surface through the elastic force of the two return springs, keeping it taut.
[0011] Preferably, the inner wall of the connecting strip is provided with two pairs of limiting grooves, and two limiting posts are fixedly connected to both sides of the push rod. The two pairs of limiting posts are movably connected to the two pairs of limiting grooves respectively. The front and rear sides of the connecting strip are fixedly connected with sliders for limiting.

[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. A push rod is installed under the fabric. The push rod is in contact with the fabric surface by the elastic force of two return springs, keeping it in a taut state.

[0023] Example
[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application effectively solves the problem that many devices have fixed adjustment mechanisms, making it impossible to adjust tension according to the thickness, material, and other characteristics of the fabric. This leads to wrinkles and loosening of the fabric during transport, affecting cutting accuracy. Regarding fabric anti-shifting, existing devices have fixed anti-shifting plates, which cannot meet the cutting needs of fabrics of different widths. The overall approach is as follows:
[0025] To address the problems existing in the prior art, this utility model provides a raincoat fabric cutting device, including a frame 1, a conveying mechanism 3, and a cutting mechanism 4. A control panel 2 is provided on the surface of the frame 1. Two limiting strips 11 for limiting movement are movably engaged on the inner wall of the frame 1. Support brackets 10 are fixedly connected to the opposite sides of the two limiting strips 11. A connecting strip 15 is provided inside the frame 1. A tensioning push rod 16 is movably engaged inside the connecting strip 15. Two return springs 17 for providing pushing force are fixedly connected to the lower surface of the push rod 16. A drive screw 13 is provided in front of the connecting strip 15. A rotating rod 6 is threaded between the two supports 10. Both return springs 17 are fixedly connected to the connecting strip 15. During use, the cutting mechanism 4 and the conveyor are started via the control panel 2. The conveying mechanism 3 transports the raincoat fabric, which is then cut by the cutting mechanism 4. During the cutting process, to ensure appropriate tension on the fabric, a push rod 16 is installed below the fabric. The push rod 16 is in contact with the fabric surface by the elastic force of two return springs 17, keeping it taut. To avoid overstretching, the screw 13 is rotated by holding the handle 12. During the rotation of the screw 13, the slider 14 sleeved on its surface moves due to the thread action. The movement of the slider 14 will drive the fixed connecting strip 15 to move together. The connecting strip 15 will drive the push rod 16 to move. At this time, the tension can be flexibly adjusted according to the fabric tension to ensure that the fabric maintains appropriate tension during the cutting process, avoiding wrinkling or stretching deformation of the fabric, thereby improving the cutting accuracy.
[0026] The inner wall of the connecting strip 15 has two pairs of limiting grooves 19. Two limiting posts 18 are fixedly connected to both sides of the push rod 16. The two pairs of limiting posts 18 are movably connected to the two pairs of limiting grooves 19 respectively. Sliding blocks 14 for limiting are fixedly connected to both the front and rear sides of the connecting strip 15. Two slots 5 are opened on the inner wall of the frame 1. The two slots 5 are movably connected to the two sliding blocks 14 respectively. Two positioning blocks 9 are fixedly connected to the upper surface of the frame 1. The two positioning blocks 9 are movably sleeved with two brackets 10 respectively. Two rings 7 are rotatably connected to the annular side of the rotating rod 6. Fixed rods 8 are fixedly connected to the annular side of each of the two rings 7. Both fixed rods 8 are fixedly connected to the frame 1. The upper surface of the screw 13 is fixed... The fixed connection includes a handle 12, and the screw 13 is threadedly connected to the front slider 14 of the two sliders 14. During the cutting process, in order to ensure the stability of the fabric conveying, the two brackets 10 inside the rotating rod 6 are driven to move relative to each other by rotating the screw. During the relative movement of the two brackets 10, the fixed limiting strips 11 will also move together. At this time, the two limiting strips 11 are adjusted to the required spacing according to the fabric width. The two sides of the fabric fit into the grooves opened on the surface of the two limiting strips 11, so that the fabric is restricted by the limiting strips 11 on both sides during the conveying process, thereby ensuring the accurate position of the fabric in the width direction, preventing its lateral deviation, and improving the cutting quality and conveying stability.

[0039] Screw 13: Rotates under the drive of handle 12, causing slider 14 to move through the thread action, which in turn drives connecting bar 15 and push rod 16 to move, adjusting fabric tension;
[0040] Slider 14: It is threadedly connected to screw 13, moves when screw 13 rotates, and drives connecting bar 15 to move. At the same time, it cooperates with slot 5 to play a limiting and guiding role.

[0046] Working principle:
[0047] During use, the cutting mechanism 4 and conveying mechanism 3 are activated via the control panel 2. The conveying mechanism 3 transports the raincoat fabric, which is then cut by the cutting mechanism 4. To ensure proper fabric tension during cutting, a push rod 16 is positioned below the fabric. The push rod 16 is held taut against the fabric surface by the elasticity of two return springs 17. To prevent overstretching, the screw 13 is rotated by gripping the handle 12. During rotation, the slider 14 fitted onto the surface of the screw 13 moves due to the threaded action. This movement of the slider 14 moves the fixed connecting strip 15, which in turn moves the push rod 16. At this point, the fabric tension can be adjusted according to the desired cutting speed. The tension is flexibly adjusted to ensure that the fabric maintains appropriate tension throughout the cutting process, preventing wrinkles or stretching deformation and thus improving cutting accuracy. During the cutting process, to ensure stable fabric feeding, the two inner brackets 10 are driven to move relative to each other by rotating the rotating rod 6. The relative movement of the two brackets 10 will drive the fixed limiting strips 11 to move together. At this time, the two limiting strips 11 are adjusted to the required spacing according to the fabric width. The two sides of the fabric fit into the grooves opened on the surface of the two limiting strips 11, so that the fabric is restricted by the limiting strips 11 on both sides during the feeding process, thereby ensuring the accurate position of the fabric in the width direction, preventing its lateral deviation, and improving the cutting quality and feeding stability.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
