Description

Technical Field

[0001] This utility model relates to the field of garment production technology, specifically a rapid thread-cutting device for garment production. Background Technology

[0002] A rapid thread trimming device for garment production is an automated device specifically designed for the garment manufacturing industry. It aims to efficiently and accurately remove thread ends generated during the sewing process. This device typically integrates a suction system, a cutting mechanism, and a fabric fixing device. It straightens and fixes the thread ends by suction, and then uses a blade or scissors to complete the cutting. Its core objective is to improve thread trimming efficiency, reduce manual labor intensity, and ensure consistent thread trimming quality.

[0003] Some existing thread-cutting machines have protective nets at the air inlet to prevent clothing from being sucked in. However, the presence of the nets affects the suction power, and thread ends are prone to accumulating or getting caught on the nets, further affecting the suction power. Some thread-cutting machines without protective nets require one hand to hold the machine and aim at the thread end while the other hand presses down on the fabric to prevent it from being sucked in, making it difficult to coordinate both hands. This is especially true when handling thin or elastic fabrics, which are prone to slipping. The thread-cutting time for a single garment increases, and long-term operation can easily lead to worker fatigue. Fabric movement may result in the thread end not being completely straightened, leaving residual thread ends or damaging the fabric after cutting.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this invention is to provide a rapid thread-cutting device for garment production, in order to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a quick thread cutting device for garment production, including a housing 1 and a housing 2 vertically slidably connected to its bottom. A fixed tube is fixed to the top of the housing 1, and a suction device is connected to the outside of the fixed tube. Multiple fixed plates are fixed on the outer arc wall of the housing 1 in a ring array about its axial direction. A telescopic rod 1 is connected to the bottom of the fixed plate, and a horizontal pressure plate is rotatably connected to the end of the telescopic rod 1 away from the fixed plate. Multiple grooves arranged in a circular array along the axial direction are formed on the side wall of shell one near shell two. A telescopic rod two is installed in the groove, and the telescopic end of the telescopic rod two is fixed to shell two. The outer arc wall of telescopic rod one and telescopic rod two are connected to the same connecting pipe. A vertical sliding channel is provided on the outer edge of the top of shell one. The sliding channel is set to avoid the grooves. A fixing block slides at the top opening of the sliding channel. A helical rod is coaxially fixed at the bottom of the fixing block. A spline sleeve is coaxially engaged at the bottom outer side of the helical rod. The spline sleeve is horizontally rotatably connected to the inner wall of the sliding channel. A spline shaft is coaxially slidably connected at the bottom inner arc wall of the spline sleeve.

[0007] Furthermore, a rotating groove is provided at the top of the second housing corresponding to the position of the spline shaft, the spline shaft is disposed in the rotating groove, a gear is coaxially fixed at the bottom of the spline shaft, an annular storage groove is provided on the inner arc wall of the second housing corresponding to the position of the gear, a rotating disk is horizontally rotated at the top of the inner wall of the storage groove disposed on the inner wall of the second housing, the storage groove and the bottom of the rotating groove are connected, and uniform gear teeth are provided on the outer arc wall of the rotating disk near the gear, the gear meshes with the gear teeth on the outer arc wall of the rotating disk.

[0008] Furthermore, a horizontal limiting plate is coaxially provided at the bottom of the rotating disk. On the side of the rotating disk near the limiting plate, there are multiple sliding grooves I arranged in a circular array about its axis. On the side of the limiting plate near the rotating disk, there are multiple sliding grooves II arranged in a circular array about its axis. The multiple sliding grooves I and the multiple sliding grooves II correspond one to one. The sliding groove I on the rotating disk is arc-shaped, with one end facing the axis of the rotating disk and the other end bent towards the outer edge of the rotating disk. The length direction of the sliding groove II is consistent with the radial direction of the limiting plate. The same cutting blade slides in the corresponding sliding groove I and sliding groove II. An axially penetrating air intake channel is provided at the center of the side wall of the rotating disk and the limiting plate that are close to each other.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. Through the coordinated operation of telescopic rod one and telescopic rod two, the operator presses shell two onto the clothing, causing shell one to descend while simultaneously forcing telescopic rod two to retract. This causes telescopic rod one to extend synchronously, driving the pressure plate to further press the surrounding fabric, forming a stable working area. Thus, only one hand is needed to ensure stability during cutting while avoiding the clothing being sucked in.

[0010] 2. The drive mechanism enables one-button cutting. Pressing simultaneously activates fabric pressing, thread suction, and cutting, greatly improving work efficiency. Furthermore, the mechanical transmission structure is simple, and maintenance costs are lower than those of electric cutting mechanisms. Attached Figure Description

[0013] 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.

[0014] Please see the appendix Figure 1 To be continued Figure 4 The present invention provides a rapid thread cutting device for garment production: including a housing 10 and a housing 2 11 vertically slidably connected to its bottom. A fixing tube 12 is fixed to the top of the housing 10, and a suction device is connected to the outside of the fixing tube 12. Multiple fixing plates 13 are fixed on the outer arc wall of the housing 10 in a ring array about its axial direction. A telescopic rod 14 is connected to the bottom of the fixing plate 13. A horizontal pressure plate 16 is rotatably connected to the end of the telescopic rod 14 away from the fixing plate 13. Multiple grooves are provided on one side wall of the housing 10 near the housing 21 in a ring array along its axial direction. A telescopic rod 25 is provided in the groove. The telescopic end of the telescopic rod 215 is fixed to the housing 21. The corresponding telescopic rod 14 and the outer arc wall of the telescopic rod 215 are connected to the same connecting pipe 141. The outer edge of the top of the housing 10 is provided with a vertically penetrating sliding channel. The sliding channel is set to avoid the groove. A fixing block 20 is slidably attached to the top opening of the sliding channel. A spiral rod 21 is coaxially fixed to the bottom of the fixing block 20. The outer bottom end of the spiral rod 21 is coaxially engaged with a spline sleeve 22, the spline sleeve 22 is horizontally rotatably connected to the inner wall of the sliding channel, and the bottom end of the inner arc wall of the spline sleeve 22 is coaxially slidably connected to a spline shaft 23. The top of the housing 11 is provided with a rotating groove corresponding to the position of the spline shaft 23. The spline shaft 23 is disposed in the rotating groove. A gear 24 is coaxially fixed at the bottom of the spline shaft 23. An annular storage groove is provided on the inner arc wall of the housing 11 corresponding to the position of the gear 24.

[0015] It should be noted that: the first shell 10 is a fixed base, and the top is connected to the suction device through the fixed pipe 12. The second shell 11 can slide vertically along the bottom of the first shell 10. The initial position is at the highest point, the first telescopic rod 14 is in the retracted state, the pressure plate 16 is away from the fabric, and the second telescopic rod 15 is in the extended state, supporting the second shell 11. The telescopic rod 14 and the telescopic rod 2 15 have the same structure and are both pre-filled with pressurized gas. They are connected to each other through the connecting pipe 141. When the telescopic rod 2 15 retracts, the compressed gas is forced into the telescopic rod 14 through the connecting pipe 141, causing it to extend. Furthermore, a return spring is fitted on the outer arc wall of the telescopic end of both the telescopic rod 14 and the telescopic rod 2 15 for easy reset. The shell 11 is pressed down vertically, causing it to slide downward along the bottom of the shell 10. The telescopic rod 15 is compressed, and its contraction is synchronously transmitted to the telescopic rod 14 through the connecting pipe 141. The telescopic rod 14 extends and pushes the pressure plate 16 to move horizontally inward, pressing the fabric from all sides to prevent it from sliding. In particular, it also prevents some lighter clothing fabrics from being directly sucked into the shell 10. When the housing 11 is pressed down to its lowest point, the suction device is activated through the fixed pipe 12. The suction force can straighten the threads on the fabric for subsequent cutting.

[0016] Please see the appendix Figure 1 To be continued Figure 4 The present invention provides a technical solution: a rotating disk 25 is horizontally rotated at the top of the inner wall of the storage groove on the inner wall of the housing 21. The storage groove and the bottom of the rotating groove are connected. The outer arc wall of the rotating disk 25 is provided with uniform gear teeth at one end near the gear 24. The gear 24 and the gear teeth on the outer arc wall of the rotating disk 25 mesh with each other. The bottom of the rotating disk 25 is coaxially provided with a horizontal limiting disk 27. The rotating disk 25 is provided with a plurality of sliding grooves I distributed in a ring array about its axial direction on the side near the limiting disk 27. The limiting disk 27 is provided with a plurality of sliding grooves II distributed in a ring array about its axial direction on the side near the rotating disk 25. The plurality of sliding grooves I and the plurality of sliding grooves II correspond one to one. The first groove on the rotating disk 25 is arc-shaped, with one end facing the axis of the rotating disk 25 and the other end bent towards the outer edge of the rotating disk 25. The length direction of the second groove is consistent with the radial direction of the limiting disk 27. The same cutter 26 slides in the corresponding first and second grooves. The rotating disk 25 and the limiting disk 27 are both provided with an axially penetrating air intake channel at the center of their respective side walls.

[0017] It should be noted that when the housing 21 is pressed down, the spline shaft 23 and spline sleeve 22 adapt to the change in axial distance. The gear 24 and the outer arc wall teeth of the rotating disk 25 are always meshed to drive the rotating disk 25 to rotate. The meshing of the helical rod 21 and the spline sleeve 22 allows the vertical motion of the helical rod 21 to be converted into the horizontal rotation of the spline sleeve 22 when the helical rod 21 slides. This further meshes with the rotation of the rotating disk 25, driving multiple cutters 26 to move synchronously in the radial direction to complete the shearing. When the rotating disk 25 rotates, the arc-shaped groove on it drives the cutter 26 to slide along the radial groove of the limiting disk 27 towards the air intake channel. The cutter 26 moves radially from the initial position towards the air intake channel to cut the straightened thread end. After the cutting is completed, the operator releases the housing 11, and the telescopic rod 15 extends under the action of the spring, pushing the housing 11 to rise. The telescopic rod 14 retracts synchronously, the pressure plate 16 releases the fabric, the spline shaft 23 and the gear 24 move upward, the rotating disk 25 stops rotating, and the device returns to its initial state.

[0018] Working principle: The shell 11 is pressed down vertically, the telescopic rod 15 retracts, and the gas is pressed into the telescopic rod 14 through the connecting pipe 141, pushing the pressure plate 16 to horizontally press the fabric. Simultaneously pressing the fixing block 20 triggers the spiral rod 21 to mesh with the spline sleeve 22, changing the vertical motion to horizontal rotation. This drives the gear 24 via the spline shaft 23, which in turn drives the rotating disk 25 to rotate. The arc-shaped slide groove one of the rotating disk 25 is linked with the radial slide groove two of the limiting disk 27, causing the cutter 26 to radially cut into the wire end. The suction device pulls the straight wire end through the fixing pipe 12, and the cutter 26 resets after completing the cutting.
