Description

Technical Field

[0001] This utility model relates to the field of packaging bag manufacturing, specifically to a fabric cutting and collection device. Background Technology

[0002] Fabrics are commonly used materials in decoration. They include various types of fabrics such as synthetic fiber carpets, non-woven wall coverings, linen, nylon, colored adhesive tape, and flannel. Fabrics play a significant role in decoration and display, often being an indispensable mainstay of the entire sales space.

[0003] Fabric cutting machines are used in fabric processing, such as the currently used fabric cutting disc cutter machine, which includes a cutter frame, a fabric feeding frame, a disc cutter mechanism, and a waste collection device. The fabric feeding frame is horizontally arranged at the front end of the cutter frame, the disc cutter mechanism is located at the upper end of the cutter frame, and the waste collection device is located at the bottom of the disc cutter mechanism and inside the cutter frame.

[0004] The fabric enters the disc cutter mechanism between the support plate and the pressure plate via the feed frame. First, the feed frame adjusts and controls the width, position, and tension of the fabric. Then, the pressure plate presses down on the fabric above the support plate. The magnetic switches on the support and pressure cylinders sense the position reached. When the fabric is pulled to the required size and position, the support plate and the pressure plate retract together. The rotary cylinder controls the circular cutter to move left and right. The fabric is cut by the cooperation of the circular cutter and the bottom cutter. After the fabric is cut, the circular cutter stops at the other end, waiting for the next command. The rotary cylinder adjusts the angle of the circular cutter, the rotary motor rotates in the opposite direction, and the fabric returns to the origin after being cut. Two cuts constitute one cycle. The cut fabric lint automatically falls into the waste trough.

[0005] The fabric cutting disc cutter used above cuts the fabric directly below the machine after it is cut. Since production is continuous, the continuously cut fabric accumulates haphazardly below the equipment. Operators have to constantly collect this haphazardly accumulated fabric, which increases their workload. Utility Model Content

[0006] This invention provides a fabric cutting and collecting device, which can reduce the labor intensity of operators.

[0007] The technical solution to the above problem is as follows:

[0008] A fabric cutting and collecting device includes a frame, a first clamping mechanism, a second clamping mechanism, a first driver, a second driver, and a cutting mechanism. The first clamping mechanism is arranged longitudinally along the frame and pivotally connected to the frame. The second clamping mechanism is arranged longitudinally along the frame and pivotally connected to the frame, and is located below the first clamping mechanism. The first driver is connected to the first clamping mechanism, and the second driver is connected to the second clamping mechanism. The cutting mechanism is arranged longitudinally along the frame and fixed to the frame, and is located between the first and second clamping mechanisms. The device also includes a suspension mechanism for suspending the cut fabric. The suspension mechanism is mounted on the frame and is located below the second clamping mechanism.

[0009] A suspension mechanism is installed below the second clamping mechanism. First, the fabric passes through the first clamping mechanism and the second clamping mechanism, and then passes between the suspension mechanism and the pressure component. A portion of the fabric is clamped between the suspension mechanism and the pressure component. After the fabric is cut by the cutting mechanism in the first and second clamping mechanisms and falls, it is suspended on the suspension mechanism in a U-shape. Multiple fabrics can be stacked on the suspension mechanism, which avoids the fabric from scattering and piling up after being cut. When the operator removes the stacked fabrics from the suspension mechanism, multiple fabrics can be removed at once, thereby reducing the operator's labor intensity. Attached Figure Description

[0026] The first cutter holder assembly 7 is slidably engaged with the first mounting base 2, and fixed to the first flexible transmission mechanism 5.

The ultrasonic welding component 7c engages with the first cutter assembly 8.

[0027] The first cutting blade assembly 8 is slidably engaged with the first mounting base 2. The first cutting blade assembly 8 is fixed to the second flexible transmission mechanism 6. When the second flexible transmission mechanism 6 is working, it drives the first cutting blade assembly 8 to move longitudinally along the frame A.

[0028] The suspension mechanism G is used to suspend the cut fabric. The suspension mechanism G is mounted on the frame A and is located below the second clamping mechanism C. The suspension mechanism G includes a second mounting base 9, a fourth driver 10, a third drive shaft 11, a third flexible transmission mechanism 12, and a rod-shaped assembly 13 for suspending the cut fabric. The second mounting base 9 is arranged laterally along the frame A and is fixed to the frame A. The fourth driver 10 is connected to the third drive shaft 11 and is supported by the frame A. The fourth driver 10 preferably uses a geared motor. Both ends of the third drive shaft 11 are connected to the third flexible transmission mechanism 12.

[0029] The third flexible transmission mechanism 12 is arranged laterally along the frame A and is mounted on the second mounting base 9. Both ends of the rod-shaped assembly 13 are connected to the third flexible transmission mechanism 12. The third flexible transmission mechanism 12 preferably uses a belt drive mechanism. The rod-shaped assembly 13 is slidably fitted with the second mounting base 9. The rod-shaped assembly 13 includes a connecting block, a slider, and a connecting rod. The connecting block is fixed to the third flexible transmission mechanism 12, the slider is fixed to the connecting block, and both ends of the connecting rod are fixed to the connecting block and / or the slider, respectively.

[0030] This utility model also includes a pressure application component H, which includes a third mounting base 14, an intermediate connecting component, and a pressure plate 15 that cooperates with the suspension mechanism G to clamp the cut fabric.

The first linear actuator 17 is preferably a cylinder.

[0031] The working process of this utility model is as follows: one end of the fabric passes through the first clamping mechanism B and the second clamping mechanism C. Then, after one end of the fabric passes between the pressure plate 15 and the rod-shaped assembly 13, the first linear actuator 17 operates, driving the pressure plate 15 to feed towards the rod-shaped assembly 13. The fabric is clamped between the pressure plate 15 and the rod-shaped assembly 13. The first clamping mechanism B and the second clamping mechanism C stop operating, and the fabric located between the first clamping mechanism B and the second clamping mechanism C is in a taut state. The linear actuator 8c drives the blade holder 8d to feed towards the ultrasonic welding component 7c. The fabric is clamped between the cutter assembly 8e and the ultrasonic welding component 7c. The third actuator 1 operates, driving the first drive shaft 3 to rotate. The first drive shaft 3 drives the first flexible transmission mechanism 5 and the second flexible transmission mechanism 6. The linear transmission mechanism 6 moves, thereby causing the first blade holder assembly 7 and the first cutting blade assembly 8 to move. During this process, the fabric located between the first clamping mechanism B and the second clamping mechanism C is cut by the first blade holder assembly 7 and the first cutting blade assembly 8. The linear driver 8c resets, creating a gap between the cutting blade assembly 8e and the ultrasonic welding component 7c. The first clamping mechanism B and the second clamping mechanism C operate, wherein the cut fabric moves downward under the action of the second clamping mechanism C. After the cut fabric separates from the second clamping mechanism C, the other end of the fabric falls freely downward under the action of gravity. Since a part of the fabric is clamped between the pressure plate 15 and the rod-shaped assembly 13, the other end of the fabric is suspended on the rod-shaped assembly 13 after free fall. Each piece of fabric is U-shaped after being suspended on the rod-shaped assembly 13. Then, the first linear driver 17 resets, creating a gap between the pressure plate 15 and the rod assembly 13. The fabric conveyed by the first clamping mechanism B passes through the second clamping mechanism C and then passes between the pressure plate 15 and the rod assembly 13. This process is repeated, causing multiple cut fabrics to be suspended sequentially on the rod assembly 13. When the fabric accumulated on the rod assembly 13 reaches a set quantity, the fourth driver 10 operates to drive the third drive shaft 11 to rotate. The third drive shaft 11 drives the third flexible transmission mechanism 12 to move, which in turn drives the rod assembly 13 to move, causing the rod assembly 13 to retract to the outside of the frame A. The operator removes the fabric stacked on the rod assembly 13 and then resets the rod assembly 13 to continue production.
