Description

Technical Field

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

[0002] Bag manufacturing is a systematic process that integrates design, craftsmanship, and materials. From the initial style design and pattern making to the selection of fabrics and accessories, and then through multiple processes such as cutting, sewing, and assembly, various materials are transformed into bag products with practical and aesthetic attributes. Among them, fabric cutting is an important starting point in the manufacturing process. Based on the precise paper pattern dimensions, combined with the texture, elasticity, and extensibility of the fabric, cutting equipment is used to efficiently and accurately divide the fabric into the required components, laying a good foundation for the subsequent sewing process.

[0003] Currently, in the cutting of bag fabrics, manual punching machines are typically used to cut the fabric into specified sizes and shapes. During the punching process, operators need to place the punching die on top of multiple stacks of fabric, and then use the manual punching machine to press down and push the punching die to cut the fabric. Due to the soft nature of the fabric, it is difficult to ensure that the punching die is in a vertical position during the placement of the die, resulting in deviations in the size of the cut pieces and skewed edges. This is especially true for complex shapes or small-sized fabric parts, where the accuracy error is more obvious, affecting the fit of subsequent sewing and splicing. Existing technology has not solved this problem. Utility Model Content

[0004] The purpose of this invention is to provide a fabric cutting device for bag processing. By setting an adjustment component, the position of the die can be flexibly adjusted, ensuring that the operator can easily move the die during the die-cutting process, thereby ensuring processing efficiency. Furthermore, the adjustment component can support the die and ensure that it is in a vertical position, thereby ensuring cutting accuracy, improving the fit of subsequent sewing and splicing, and thus improving product quality, thereby solving the problems mentioned in the background art.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figures 1-4 This utility model provides a technical solution:

[0023] A fabric cutting device for bag processing includes a stamping assembly for providing downward pressure. The stamping assembly includes a lower pressure plate 2, with four sets of support rods 3 slidably engaged around its perimeter. The bottoms of the support rods 3 are fixedly mounted on a stamping table 4. A stamping plate 5 is slidably mounted on the top surface of the stamping table 4, with its bottom abutting against and slidably engaged with the top surface of the stamping table 4. A guide slider 14 is fixedly mounted on the bottom of the stamping plate 5. A guide groove 15 is formed on the top surface of the stamping table 4, and the guide slider 14 slidably engages with the guide groove 15. The center of the top surface of the lower pressure plate 2 is fixedly connected to the telescopic end of a hydraulic cylinder 16. The pressure cylinder 16 is fixedly installed at the center of the top surface of the top plate 17, and the top plate 17 is fixedly connected to the top of the support rod 3. The bottom of the stamping table 4 is fixedly installed with an equipment box. The equipment box is based on a hydraulic system and electrical control. It contains a hydraulic component consisting of a hydraulic pump, oil tank, overflow valve, reversing valve and hydraulic oil pipe. It is equipped with a drive motor to provide power to the hydraulic cylinder 16. At the same time, it is equipped with an electrical control module containing a control box and an overload protection device (or PLC controller) to receive operation signals and regulate the operation of the equipment, providing stable power output and precise control for this device, and ensuring efficient and safe stamping process.

[0024] By setting up a pressing component, a stable and controllable downward pressure can be provided. The hydraulic cylinder 16 provides a stable and adjustable downward pressure, driving the pressing plate 2 to press down precisely and vertically along the support rod 3. When the pressing plate 2 moves downward, it can evenly transmit the pressure to the punching die 1, ensuring that the punching die 1 can thoroughly punch out multi-layered or different thicknesses of bag fabric, avoiding problems such as fabric edge tearing and incomplete punching caused by insufficient pressure. At the same time, by utilizing the sliding cooperation between the stamping plate 5 and the stamping table 4, the operator can pull out the stamping plate 5 during the processing, thereby flexibly adjusting the position of the punching die 1. Combined with the downward pressing action of the pressing plate 2, continuous punching of different areas of fabric can be achieved, providing a power guarantee for efficient mass production.

[0025] It also includes a die-cutting mold 1 for cutting fabric, a mounting slide 6 and mounting grooves 7 on both sides of the die-cutting mold 1 engaging with each other, two sets of fixing screws 11 are provided on both sides of the mounting slide 6, the fixing screws 11 slide and rotate within the mounting holes of the mounting slide 6, and the fixing screws 11 are threaded into the mounting grooves 7.

[0026] By setting up the die-cutting mold 1, the fabric can be cut in conjunction with the pressing component. The shape and size of the die-cutting mold 1 are strictly matched with the specifications of the cut pieces required for the bag fabric. Whether it is a simple rectangle, a circle, or a complex irregular structure, it can be accurately cut in one go through the corresponding die-cutting mold 1. The edges of the die-cutting mold 1 are specially treated (such as sharpening and wear-resistant coating), which can quickly cut the fabric under pressure, ensuring that the edges of the cut pieces are smooth and neat, and reducing quality problems such as burrs and snags. At the same time, the mounting grooves 7 on both sides of the die-cutting mold 1 are compatible with the mounting slides 6 of the adjusting component, which not only facilitates the quick replacement of die-cutting molds 1 of different specifications to meet the needs of diverse cut pieces, but also works with the adjusting component during the cutting process to stably bear the pressure transmitted by the pressing component, ensuring the consistency and reliability of each cutting.

[0027] It also includes an adjustment assembly for adjusting the position of the blanking die 1. The adjustment assembly includes two sets of symmetrically arranged mounting slides 6. The mounting slides 6 are slidably mounted on the longitudinal slide rod 8. The two ends of the longitudinal slide rod 8 are slidably engaged with the transverse slide rod 9. The two ends of the transverse slide rod 9 are slidably engaged with the vertical slide rod 10. The bottom of the vertical slide rod 10 is fixedly mounted on the support frame 12. The support frame 12 is fixedly connected to both sides of the stamping plate 5. A compression spring 13 is slidably sleeved on the surface of the vertical slide rod 10. The top of the compression spring 13 abuts against the bottom of both ends of the transverse slide rod 9, and the bottom of the compression spring 13 abuts against the support frame 12.

[0028] By setting up adjustment components, the position of the die-cutting mold 1 can be flexibly switched, and the verticality of the die-cutting mold 1 is ensured. Through the sliding cooperation between the mounting slide 6 and the longitudinal slide bar 8, the die-cutting mold 1 can move freely along the longitudinal slide bar 8. The cooperation between the longitudinal slide bar 8 and the transverse slide bar 9 realizes the transverse position adjustment. The sliding of the transverse slide bar 9 along the vertical slide bar 10 provides the die-cutting mold 1 with vertical movement space. The three work together to enable the die-cutting mold 1 to be accurately positioned in three-dimensional space, meet the die-cutting needs of different parts of the fabric, and improve the fabric utilization rate. In addition, the snap-fit ​​structure between the mounting slide 6 and the die-cutting mold 1 and the locking effect of the fixing screw 11 can stabilize the die-cutting mold 1. Combined with the limit of the transverse slide bar 9 by the vertical slide bar 10, it is ensured that the die-cutting mold 1 is always in a vertical state, fundamentally avoiding the deviation of the cut piece size caused by tilting, and laying a precise foundation for the subsequent sewing process.

[0029] In practical use, install the device in the designated position and first check whether the hydraulic system and electrical control module inside the equipment box are operating normally. During operation, the operator lays the bag fabric to be cut flat on the stamping plate 5, rotates the appropriate cutting die 1 according to the cutting requirements, installs it onto the mounting slide 6, and tightens the fixing screws 11 on both sides of the mounting slide 6 to fix the cutting die 1. Adjust the position of the cutting die 1 by adjusting the components: push the mounting slide 6 to slide along the longitudinal slide bar 8 to achieve longitudinal positioning, move the longitudinal slide bar 8 to slide along the transverse slide bar 9 to complete the transverse adjustment, align it with the designated position on the fabric, and after adjustment... Push the stamping plate 5 to move the blanking die 1 and other components below the lower pressure plate 2. Then start the equipment. The hydraulic cylinder 16 drives the lower pressure plate 2 to press down vertically along the support rod 3. The downward pressure pushes the blanking die 1 to move downward and blank the fabric. During the blanking process, the transverse slide bar 9 moves downward with the blanking die 1, and the compression spring 13 is compressed and contracts. After the blanking is completed, the compression spring 13 pushes the transverse slide bar 9 to reset. After completing one blanking cycle, pull the stamping plate 5 to pull the adjustment component and the blanking die 1 and other components out from below the lower pressure plate 2, or repeat the above adjustment steps to move the blanking die 1 to the next blanking position for the next blanking cycle.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
