Description

Technical Field

[0001] This utility model relates to the field of embroidery machine technology, and more specifically, to a thread clamping structure on an embroidery machine. Background Technology

[0002] Embroidery, as a traditional and exquisite decorative craft, still occupies an important position in the modern textile industry. The advent of embroidery machines has greatly improved the production efficiency and quality of embroidery. Computerized embroidery machines are the most advanced embroidery machinery of our time, enabling traditional hand embroidery to be completed at high speed and efficiency, and achieving the requirements of "multi-layered, multi-functional, uniform, and perfect" results that hand embroidery cannot reach. It is an electromechanical product embodying various advanced technologies, and the thread clamping structure of the embroidery machine plays a crucial role in the embroidery effect.

[0003] Chinese patent application CN201721654916.4 discloses a thread clamping device for a multi-thread embroidery machine, comprising two sets of parallel and vertically arranged support plates. A horizontally arranged top plate is bolted to the top of the support plates. A push rod motor is connected to the bottom center of the top plate, and the push rod motor is perpendicular to the top plate. A connecting rod is welded to the output shaft of the push rod motor. This utility model has a simple structure and novel design, and can clamp multiple broken threads simultaneously, preventing the broken threads from moving further, making it easier for workers to find the broken thread joints, and improving the efficiency of thread reconnection.

[0004] However, as can be seen from the accompanying drawings in the instruction manual, when multiple threads are clamped, they are only clamped by two rollers. When multiple threads are being transported, they are prone to horizontal movement due to thread breakage, which can cause adjacent threads to cross and become entangled, affecting the transport effect and making it inconvenient to separate and limit the transported threads. Therefore, a thread clamping structure for embroidery machines is proposed. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a thread clamping structure for embroidery machines to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a thread clamping structure for an embroidery machine, comprising a frame, two first limiting grooves on one side of the frame, a first limiting slider in the middle of the first limiting groove, and multiple thread dividing rods on the side of the frame near the first limiting sliders. First screws are symmetrically inserted into both ends of each thread dividing rod, and a pressing screw head is fixedly connected to one end of each first screw. The thread dividing rods can separate and limit multiple threads used for embroidery, preventing them from tangling. By rotating the pressing screw head to control the rotation of the first screws, the thread dividing rods can be pressed against the wall of the frame. Through cooperation with the first limiting sliders, the position of the thread dividing rods can be fixed. By controlling the sliding of the first limiting sliders inside the first limiting grooves, the thread dividing rods can be moved on one side of the frame for easy adjustment and use.

[0007] A fixed roller is rotatably connected to the bottom of the inner cavity of the frame, a support frame is provided at the top of the inner cavity of the frame, a lifting plate is provided at the top of the support frame, and a movable roller is rotatably connected to the bottom of the support frame. Multiple limiting grooves are symmetrically opened on the surfaces of the movable roller and the fixed roller. Connecting rods are symmetrically fixedly connected to the top two sides of the support frame. A spring is sleeved in the middle of the connecting rod. The top of the connecting rod passes through the lifting plate and is fixedly connected to the first limiting plate. The fixed roller and the movable roller can clamp and fix the wire located in the middle of the limiting groove. The lifting plate can move up and down, and the connecting rod and the spring can control the up and down movement of the support frame. It is convenient to control the up and down movement of the movable roller. The compression of the spring can achieve the clamping and buffering effect.

[0008] A second screw is inserted into the top of the frame. A third limiting slider and a second limiting slider are fixedly connected to both sides of the lifting plate and the support frame, respectively. A second limiting groove is symmetrically opened on both sides of the inner cavity of the frame. The stability of the support frame and the lifting plate moving up and down is improved by the cooperation of the third limiting slider and the second limiting slider with the second limiting groove. The up and down movement of the lifting plate is controlled by rotating the second screw, which is convenient for driving.

[0009] Preferably, one end of the first screw is rotatably connected to one side wall of the first limiting slider, the extrusion screw head is threadedly connected to the dividing rod, and the dividing rod corresponds to the first limiting slider. By rotating the extrusion screw head to control the rotation of the first screw, the dividing rod can be driven to extrude against the frame, which facilitates fixing the position of the dividing rod.

[0010] Preferably, the outer surfaces of both the fixed roller and the movable roller are provided with rubber pads, the dividing rod and the limiting groove are offset from each other, and the cross-sectional shape of the support frame is set to "U" shape. The rubber pads can buffer the wires located in the middle of the limiting groove when the fixed roller and the movable roller clamp them. At the same time, the limiting groove limits the feeding of the wires, thereby improving the performance.

[0011] Preferably, the bottom end of the second screw passes through the lifting plate, and two second limiting plates are fixedly connected to the bottom end of the second screw. The two second limiting plates are respectively set on the upper and lower sides of the lifting plate. By rotating the turntable, the second screw drives the second limiting plates to move the lifting plate up and down, which is convenient for driving.

[0012] Preferably, the third limiting slider and the second limiting slider have the same cross-sectional shape, the third limiting slider is fixed on both sides of the lifting plate, and the second limiting slider is fixed on both sides of the support frame.

[0013] Preferably, the third limiting slider is adapted to the second limiting slide groove, and both the third limiting slider and the second limiting slider are located in the middle of the second limiting slide groove. The cooperation between the third limiting slider, the second limiting slider and the second limiting slide groove improves the stability of the lifting plate and the support frame moving up and down.

[0014] Preferably, mounting plates are symmetrically fixedly connected to the bottom of both sides of the frame, and mounting holes are opened on the surface of the mounting plates. The second screw is threadedly connected to the top wall of the frame, and the frame can be easily installed and fixed through the mounting plates and mounting holes.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model firstly uses a dividing rod to separate and limit the conveyed threads, so that when one thread breaks, it will not affect the adjacent threads, thus playing a limiting and separating role. Furthermore, the limiting groove can improve the stability of the threads when the fixed roller and the movable roller clamp or convey them, preventing the threads from moving horizontally due to excessively loose conveying, which would affect the conveying or clamping effect and improve the use effect.

[0017] 2. This utility model also allows the first limiting slider to slide inside the first limiting groove, which can adjust the position of the dividing rod as needed. The rubber pads on the surfaces of the fixed roller and the movable roller can limit the clamping of the wire. The spring is squeezed by the lifting plate and the support frame, which can buffer the clamping strength of the movable roller and the fixed roller on the wire. The stability of the movement of the lifting plate and the support frame is improved by the cooperation of the third limiting slider and the second limiting slider with the second limiting groove.

[0018] In summary, through the interaction of the above-mentioned multiple functions, the conveyed threads can be separated and limited, so that the breakage of one thread will not affect the normal use of adjacent threads, and the clamping of the threads is limited while providing buffering.

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.

[0025] As attached Figure 1-4 The thread clamping structure on the embroidery machine shown includes a frame 1. Two first limiting grooves 2 are opened on one side of the frame 1. A first limiting slider 3 is set in the middle of the first limiting groove 2. Multiple thread dividing rods 4 are set on the side of the frame 1 near the first limiting slider 3. First screws 5 are symmetrically inserted at both ends of the thread dividing rods 4. A pressing screw head 6 is fixedly connected to one end of the first screw head 5. The thread dividing rods 4 can separate and limit the multiple threads used for embroidery to prevent them from tangling. By rotating the pressing screw head 6, the first screws 5 can be rotated, which can make the thread dividing rods 4 press against the wall of the frame 1. By cooperating with the first limiting slider 3, the position of the thread dividing rods 4 can be fixed. By controlling the sliding of the first limiting slider 3 inside the first limiting groove 2, the thread dividing rods 4 can be moved on one side of the frame 1 for easy adjustment.

[0026] A fixed roller 7 is rotatably connected to the bottom of the inner cavity of frame 1, a support frame 8 is provided at the top of the inner cavity of frame 1, a lifting plate 11 is provided at the top of the support frame 8, and a movable roller 9 is rotatably connected to the bottom of the support frame 8. Multiple limiting grooves 10 are symmetrically opened on the surfaces of the movable roller 9 and the fixed roller 7. Connecting rods 12 are symmetrically fixedly connected to the top two sides of the support frame 8. A spring 14 is sleeved in the middle of the connecting rod 12. The top of the connecting rod 12 passes through the lifting plate 11 and is fixedly connected to the first limiting plate 13. The fixed roller 7 and the movable roller 9 can clamp and limit the wire located in the middle of the limiting groove 10 while clamping and fixing it. The lifting plate 11 can move up and down, and the connecting rod 12 and the spring 14 can control the up and down movement of the support frame 8, which is convenient for controlling the up and down movement of the movable roller 9. The clamping buffering effect can be achieved by squeezing the spring 14.

[0027] A second screw 18 is inserted into the top of the frame 1. A third limiting slider 16 and a second limiting slider 15 are fixedly connected to both sides of the lifting plate 11 and the support frame 8, respectively. A second limiting groove 17 is symmetrically opened on both sides of the inner cavity of the frame 1. The stability of the support frame 8 and the lifting plate 11 moving up and down is improved by the cooperation of the third limiting slider 16 and the second limiting slider 15 with the second limiting groove 17. The lifting plate 11 can be controlled to move up and down by rotating the second screw 18, which is convenient for driving.

[0028] As attached Figure 1-3 As shown, one end of the first screw 5 is rotatably connected to one side wall of the first limiting slider 3, and the extrusion screw head 6 is threadedly connected to the dividing rod 4. The dividing rod 4 corresponds to the first limiting slider 3. By rotating the extrusion screw head 6, the first screw 5 can be rotated, which can drive the dividing rod 4 to extrude against the frame 1, making it convenient to fix the position of the dividing rod 4.

[0029] As attached Figure 1-4As shown, rubber pads are provided on the outer surfaces of both the fixed roller 7 and the movable roller 9. The dividing rod 4 and the limiting groove 10 are offset from each other. The cross-sectional shape of the support frame 8 is set as "U". The bottom end of the second screw 18 passes through the lifting plate 11. Two second limiting plates 19 are fixedly connected to the bottom end of the second screw 18. The two second limiting plates 19 are respectively set on the upper and lower sides of the lifting plate 11. The cross-sectional shape of the third limiting slider 16 and the second limiting slider 15 are the same. The third limiting slider 16 is fixed on both sides of the lifting plate 11, and the second limiting slider 15 is fixed on both sides of the support frame 8. The third limiting slider 16 is adapted to the second limiting groove 17. The third limiting slider 16 and the second limiting slider 15 are both set in the middle of the second limiting groove 17. Mounting plates 21 are symmetrically fixed to the bottom of both sides of the frame 1. Mounting plates 21 have mounting holes on their surfaces. The second screw 18 is threadedly connected to the top wall of the frame 1. The rubber pads act as a buffer when the fixed roller 7 and the movable roller 9 clamp the wire located in the middle of the limiting groove 10.

The mounting plates 21 and mounting holes facilitate the installation and fixing of the frame 1.

[0030] The working principle of this utility model is as follows: the frame 1 is easily fixed in the preset position of the embroidery machine by rivets passing through the mounting holes on the mounting plate 21, and then the silk thread is conveyed between the two dividing rods 4 and between the fixed roller 7 and the movable roller 9.

[0031] Then, rotating the second screw 18 controls the lifting plate 11 to drive the support frame 8 to control the movable roller 9 to move downward. Through cooperation with the fixed roller 7, the wire is clamped and fixed. At the same time, through the limiting groove 10 and the rubber pads on the surface of the fixed roller 7 and the movable roller 9, the clamped wire can be limited and buffered. And through the compression of the spring 14 by the lifting plate 11 and the support frame 8, the compression intensity between the movable roller 9 and the fixed roller 7 can be buffered.

[0032] By rotating the extrusion screw head 6 and controlling the first limiting slider 3 to slide inside the first limiting groove 2, the position of the dividing rod 4 can be adjusted, improving the performance.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
