Description

Technical Field

[0001] This utility model relates to the technical field of cotton yarn production equipment, specifically a cotton yarn sliver cutting mechanism for cotton yarn production. Background Technology

[0002] In the production process of cotton yarn for curtains, cutting the cotton yarn strips to a specific length is an important prerequisite for the smooth progress of subsequent weaving processes.

[0003] Currently, the industry relies heavily on manual operation or simple mechanical devices for cutting cotton yarn strips. Manual cutting requires operators to repeatedly perform positioning and cutting actions, completing only one strip at a time. Processing large quantities of cotton yarn strips for curtain production is extremely time-consuming and subject to human error, making it difficult to guarantee uniform cutting lengths. This results in dimensional deviations in the woven curtains, severely impacting product quality. Existing simple mechanical devices often cut only one strip at a time, requiring the rearrangement of new strips before the next operation. This inefficient work model is far from meeting the growing large-scale production needs of curtain manufacturers.

[0004] Moreover, the large amount of debris generated during the cutting process will be scattered on the workbench, which is difficult to clean. This not only pollutes the production environment, but may also enter the mechanical device, causing equipment failure, increasing equipment maintenance costs, and affecting the continuity of production. Summary of the Invention

[0005] To address the shortcomings mentioned in the background art, the purpose of this utility model is to provide a cotton yarn cutting mechanism for cotton yarn production, so as to solve the problems of low cutting efficiency, poor precision, and inconvenient debris cleaning in the prior art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A cotton yarn sliver cutting mechanism for cotton yarn production includes a worktable with a cutting component. The worktable has a hollow interior and a plurality of staggered first and second transverse grooves are provided on the top of the worktable. A first slide block and a second slide block are slidably disposed in the first and second transverse grooves, respectively. Vertically arranged pull rods are fixedly installed on the first and second slide blocks. The multiple pull rods cooperate to pull the cotton yarn sliver into an S-shape. The mechanism also includes a driving component for driving the first and second slide blocks to move closer or further apart.

[0008] The cutting assembly includes a crossbeam fixedly installed on a workbench, a protective shell fixedly connected to the crossbeam, a hydraulic rod vertically arranged inside the protective shell, a cutter fixedly connected to the output end of the hydraulic rod, a cutting edge for the cutter to pass through at the bottom end of the protective shell, a shearing opening communicating with a first horizontal groove and a second horizontal groove on the top of the workbench, and a V-shaped cutting groove fixedly connected inside the workbench and below the shearing opening, the cutting edge of the cutter and the cutting edge of the V-shaped cutting groove forming a shearing engagement in the vertical direction.

[0009] The drive assembly includes two symmetrically arranged push plates and a screw. One push plate is fixedly connected to each first slide block, and the other push plate is fixedly connected to each second slide block. The bottom end of the push plate fits against the top end of the worktable. Slider blocks are symmetrically arranged on the first and second slide blocks. Slider grooves that slide and engage with the sliders are symmetrically opened on the inner walls of the first and second transverse grooves. Bosses are symmetrically fixedly connected to the worktable. The screw is rotatably mounted on the two bosses. The screw is a double-threaded screw. The two push plates are respectively threaded to the two reverse threaded sections of the screw. Turntables are fixedly connected to both ends of the screw.

[0010] More preferably, the workbench is provided with two Y-shaped brackets, the groove axes of the two Y-shaped brackets are aligned with each other to support the cotton yarn roll, and pneumatic clamps are symmetrically arranged on the workbench at both ends of the shearing opening, with the clamping opening of the pneumatic clamps facing the cotton yarn output path of the Y-shaped brackets.

[0011] More preferably, the front end of the workbench is open and a waste drawer is slidably installed inside, the waste drawer being used to collect the debris generated during the cutting of cotton yarn strips.

[0012] More preferably, the left and right outer walls of the workbench are symmetrically fitted with anti-accidental activation switches, and the signal output terminals of the two activation switches are connected in parallel to the control circuit of the hydraulic rod to form a safety circuit for synchronous triggering by both hands.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model uses multiple pull rods to pull the cotton yarn strips into an S-shape, enabling the cutting of multiple cotton yarn strips at once. Compared to existing technologies that can only cut one cotton yarn strip at a time, this greatly improves production efficiency and can meet the needs of large-scale production by curtain manufacturers. The pneumatic clamps at both ends of the cutting end further ensure the stability of the cotton yarn strips during the cutting process, contributing to improved cutting efficiency and quality.

[0015] 2. This utility model, through the design of pneumatic clamps and turntables at both ends of the screw, simplifies and facilitates the feeding of cotton yarn and the adjustment of the pull rod spacing. The dual-hand synchronous trigger safety circuit effectively prevents operator error and ensures operator safety.

[0016] 3. This utility model can collect the debris generated during the cutting process in a timely manner by setting up a waste drawer, which facilitates centralized cleaning, keeps the working environment clean, reduces the impact of debris on the equipment, lowers equipment maintenance costs, and improves the service life of the equipment.

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] like Figure 1-4 As shown, a cotton yarn sliver cutting mechanism for cotton yarn production includes a workbench 1. The workbench 1 serves as the basic load-bearing structure of the entire device, and its interior is hollow, providing installation space for the waste drawer 24 and also helping to reduce the overall weight. The top of the workbench 1 has several staggered first horizontal grooves 3 and second horizontal grooves 4. First slide blocks 5 and second slide blocks 6 are slidably disposed within the first horizontal grooves 3 and second horizontal grooves 4, respectively. Vertically mounted pull rods 7 are fixedly installed on both the first slide blocks 5 and second slide blocks 6. The multiple pull rods 7 cooperate to pull the cotton yarn sliver into an S-shape. In this way, the cotton yarn sliver can be effectively fixed and stretched, ensuring the stability of the cotton yarn sliver during the cutting process, preventing slippage or twisting, and thus improving cutting accuracy. Furthermore, it includes a drive assembly 8 for driving the first slide blocks 5 and second slide blocks 6 to move closer or further apart. The drive assembly 8 can adjust the distance between the pull rods 7 according to actual production needs, thereby achieving the cutting of cotton yarn slivers of different lengths.

[0027] The cutting assembly 2 is the core component for cutting cotton yarn strips. It includes a crossbeam 9 fixedly installed on the workbench 1, which provides a stable mounting base for components such as the protective shell 10 and the hydraulic rod 11. The protective shell 10 is fixedly connected to the crossbeam 9, and the hydraulic rod 11 is vertically arranged inside the protective shell 10. The output end of the hydraulic rod 11 is fixedly connected to the cutter 12. The protective shell 10 not only protects the internal components such as the hydraulic rod 11 from external debris affecting their normal operation, but also has a cutting edge 13 at its bottom for the cutter 12 to pass through. The top of the workbench 1 has a shearing opening 14 that communicates with the first horizontal groove 3 and the second horizontal groove 4. A V-shaped cutting groove 15 is fixedly connected inside the workbench 1 and below the shearing opening 14. The cutting edge of the cutter 12 and the cutting edge of the V-shaped cutting groove 15 form a shearing engagement in the vertical direction. When the hydraulic rod 11 drives the cutter 12 to move downward, the cutter 12 cooperates with the V-shaped cutter groove 15 to quickly and accurately cut the cotton yarn strip in the S-shape, ensuring that the cut cotton yarn strip has a neat end face.

[0028] The drive assembly 8 specifically includes two symmetrically arranged push plates 16 and screws 17. One push plate 16 is fixedly connected to each first slide block 5, and the other push plate 16 is fixedly connected to each second slide block 6. The bottom end of the push plate 16 fits against the top end of the worktable 1, providing support and guidance. Slider blocks 18 are symmetrically arranged on the first slide block 5 and the second slide block 6. The inner walls of the first transverse groove 3 and the second transverse groove 4 are symmetrically provided with sliding grooves 19 that slide with the sliders 18. This structural design makes the first slide block 5 and the second slide block 6 more stable during sliding and less prone to displacement. Bosses 20 are symmetrically fixedly connected to the worktable 1. Screws 17 are rotatably mounted on the two bosses 20. The screws 17 are double-threaded screws. The two push plates 16 are respectively threaded to the two reverse-threaded sections of the screw 17, and turntables 21 are fixedly connected to both ends of the screw 17. By rotating the turntable 21, the screw 17 can be driven to rotate more easily, thereby causing the two push plates 16 to move synchronously in opposite directions under the drive of the screw 17, causing the first slide 5 and the second slide 6 to move closer or further apart, thus realizing flexible adjustment of the distance between the pull rods 7.

[0029] Two Y-shaped brackets 22 are installed on the workbench 1, with their groove axes aligned to support the cotton yarn roll and facilitate the feeding of cotton yarn. Pneumatic clamps 23 are symmetrically arranged on the workbench 1 at both ends of the shearing opening 14. The clamping openings of the pneumatic clamps 23 face the cotton yarn output path of the Y-shaped brackets 22, allowing them to quickly and firmly clamp the ends of the cotton yarn. Working in conjunction with the pull rod 7, the pneumatic clamps pull the cotton yarn into an S-shape, further ensuring the stability of the cotton yarn during the cutting process. The front end of the workbench 1 is open, and a waste drawer 24 is slidably installed inside. The waste drawer 24 collects debris generated during the cotton yarn cutting process, facilitating centralized cleaning, maintaining a clean working environment, and effectively preventing debris from entering the equipment and affecting its normal operation. The left and right outer walls of the workbench 1 are symmetrically fitted with anti-accidental activation switches 25. The signal output terminals of the two activation switches are connected in parallel to the control circuit of the hydraulic rod 11 to form a two-hand synchronous trigger safety circuit. The hydraulic rod 11 will only start when the operator presses the two activation switches at the same time, thereby effectively preventing the operator from being injured due to misoperation during the operation of the equipment and improving the safety of the equipment.

[0030] Workflow

[0031] Feeding preparation: Place the cotton yarn roll containing the cotton yarn strip on the two Y-shaped brackets 22, allowing the cotton yarn strip to naturally exit from the brackets. Pull the cotton yarn strip so that it passes between the pull rod 7 on the first slide 5 and the pull rod 7 on the second slide 6. Activate the pneumatic clamp 23 near the front end to clamp the free end of the cotton yarn strip.

[0032] Adjusting the spacing of the pull rods 7: Based on the required length of the cotton yarn to be cut, rotate the turntables 21 at both ends of the screw 17 in the drive assembly 8. Since the screw 17 is a double-threaded screw 17, and the two push plates 16 are respectively threaded to the two reverse threaded sections of the screw 17, when rotating the turntable 21 to drive the screw 17 to rotate, the two push plates 16 will drive the first slide 5 and the second slide 6 to move away from or closer to each other, thereby adjusting the spacing between the pull rods 7, so that the multiple pull rods 7 pull the cotton yarn into an S-shape of a suitable shape and length. Then, another starting clamp is activated to hold the other end of the cotton yarn, ensuring that the cotton yarn will not slip in subsequent operations.

[0033] Cutting operation: After the distance between the pull rods 7 is adjusted and the cotton yarn is in a stable S-shaped state, the operator presses the anti-accidental-touch start switch 25 on the outer walls of the left and right sides of the workbench 1 simultaneously with both hands. At this time, the control circuit is connected, the hydraulic rod 11 is activated, and its output end drives the cutter 12 to move downward. The cutter 12 passes through the blade 13 at the bottom of the protective shell 10 and the shearing opening 14 at the top of the workbench 1, and cooperates with the V-shaped blade groove 15 below to quickly and accurately cut the cotton yarn in the S-shaped state.

[0034] Collection and Cleaning: The cut cotton yarn falls below workbench 1 and can be collected manually or using other collection devices. The debris generated during the cutting process falls directly into the waste drawer 24 at the front of workbench 1. Once the waste drawer 24 is full, it can be removed for cleaning to maintain a clean working environment and ensure the normal operation of the equipment. The above steps can then be repeated for the next cotton yarn cutting operation.
