Description

Technical Field

[0001] This invention relates to the field of shredding equipment technology, and more specifically to a shredding device and winding machine that facilitates shredding replacement. Background Technology

[0002] As is well known, a winding machine mainly winds the bobbin yarn spun by a spinning machine into a cone yarn of a certain specification. Through a series of mechanical actions, such as traction, twisting and winding, it winds the yarn in an orderly manner onto the core tube. A yarn cutting device is a piece of equipment used in the textile and other industries to cut yarn when changing yarn.

[0003] Most existing winding machines use U-shaped cutting plates. When switching between full-wound yarn cakes, the tail yarn often slips and cannot be cut off, resulting in excessively long tail yarn. During the winding process, it is also very easy to form a double-tail abnormality and get caught in the bottom layer of the yarn cake, causing the yarn cake to become knotted, which in turn affects the normal winding process and even affects the quality of the yarn. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a wire cutting device and winding machine that facilitates wire replacement. It employs active cutting to cut the wire, resulting in better cutting performance, reducing the generation of double-tailed wires, and providing better protection for the wire during the pre-cutting capture process, making it more practical.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a slicing device for easy slicing, comprising two slicing plates and two electrically driven structures. Each of the two electrically driven structures includes a lead screw, a servo motor, and a slide. The two servo motors are respectively installed inside the two slicing plates, and the two lead screws are respectively rotatably connected to the two slicing plates.

Each of the two slidable frames is connected to a sliding frame. Each of the two sliding frames is fixedly connected to a connecting spring. Each of the two connecting springs is fixedly connected to the two sliding frames. Each of the two sliding frames is fixedly connected to a push-limit hook at its front end. Each of the two cutting plates is fixedly connected to an end frame at its front end. Each of the two end frames is equipped with a telescopic blade. Each of the two push-limit hooks is provided with a cutting plane. Each of the two cutting planes is matched with the two telescopic blades. Each of the two end frames is equipped with a linkage structure. Each of the two linkage structures is matched with the two sliding frames. Each of the two linkage structures is matched with the two telescopic blades.

[0006] Preferably, both of the linkage structures include support ears, which are fixedly connected to the front ends of the two end frames. A linkage frame is rotatably connected inside each of the support ears. One end of each linkage frame is connected to two telescopic blades, and the other end of each linkage frame is connected to a push rod. The two push rods are slidably connected to the two end frames. A return spring is fixedly connected to the rear end of each end frame, and the two return springs are fixedly connected to the two push rods.

[0007] Preferably, both linkage frames are provided with drive bar holes and driven bar holes, and drive shafts are connected to both drive bar holes. Both telescopic blades are provided with drive holes, and the two drive shafts are fixedly connected to the two drive holes respectively. Both driven bar holes are connected to driven shafts, and fixed ears are fixedly connected to both push rods. The two driven shafts are fixedly connected to the two fixed ears respectively.

[0010] A winding machine includes a main frame, on which a turntable is mounted. Two electrically powered winding support tubes are mounted on the turntable.

[0013] Compared with the prior art, the present invention provides a wire cutting device and a winding machine that facilitate wire changing, and has the following beneficial effects:

[0014] (1). In this invention, the electric drive structure is designed to form a corresponding capture structure with the wire, which facilitates the cutting of the wire. The wire is cut by active cutting, which has a better cutting effect and reduces the generation of double tails at the wire break.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example

[0026] Please see Figures 1-7 A slicing device for easy slicing includes two slicing plates 1 and two electrically driven mechanisms. Each of the two electrically driven mechanisms includes a lead screw 2, a servo motor 3, and a slide 4. The two servo motors 3 are respectively installed inside the two slicing plates 1. The two lead screws 2 are respectively rotatably connected to the two slicing plates 1. The output shafts of the two servo motors 3 are respectively connected to the two lead screws 2. The two slides 4 are respectively slidably connected to the two slicing plates 1 and are threadedly connected to the two lead screws 2. Each slide 4 has a sliding opening 5, and a sliding bracket 6 is slidably connected to each of the two sliding openings 5. The two sliding brackets 6 are fixedly connected. There are connecting springs 7, and two connecting springs 7 are fixedly connected to two sliding frames 6 respectively. The front end of each of the two sliding frames 6 is fixedly connected to a push limit hook 8. The front end of each of the two cutting plates 1 is fixedly connected to an end frame 9. A telescopic blade 10 is installed in each of the two end frames 9. A cutting plane 11 is set in each of the two push limit hooks 8. The two cutting planes 11 are matched with the two telescopic blades 10 respectively. Through the design of the electric push structure, a corresponding capture structure is formed with the wire, which facilitates the cutting of the wire. The cutting of the wire is achieved by active cutting, which has a better cutting effect and reduces the generation of double tail wires at the wire break.

[0027] It should be further explained that each of the two end frames 9 is equipped with a linkage structure, which is matched with each of the two carriages 4 and the two telescopic blades 10. Each linkage structure includes a support lug 12, which is fixedly connected to the front end of each of the two end frames 9. A linkage frame 13 is rotatably connected inside each support lug 12. One end of each linkage frame 13 is connected to one of the two telescopic blades 10, and the other end of each linkage frame 13 is connected to a push rod 14. Rod 14 is slidably connected to two end brackets 9. A return spring 15 is fixedly connected to the rear end of each end bracket 9. The two return springs 15 are fixedly connected to two push rods 14. Each of the two linkage frames 13 has a drive bar hole 16 and a driven bar hole 17. A drive shaft 18 is connected to each of the two drive bar holes 16. Each of the two telescopic blades 10 has a drive hole 19. The two drive shafts 18 are fixedly connected to the two drive holes 19. A driven shaft 20 is connected to each of the two driven bar holes 17. Two push rods... Each of the two push rods 14 is fixedly connected to a fixed lug 21. The two driven shafts 20 are fixedly connected to the two fixed lugs 21 respectively. Through the design of the linkage structure, the telescopic blade 10 is moved relative to the slide 4. In actual operation, before the wire cutting is formed, the cutting edge of the telescopic blade 10 is stored in the end frame 9. It is pushed out at the moment of cutting, which ensures that the wire cutting operation is carried out while the wire is captured before cutting. It is more practical. The rear ends of the two push rods 14 are fixedly connected to push connecting plates 22. The two push connecting plates 22 are fixedly connected to the two return springs 15 respectively. The two push limit hooks 8 are provided with guide slopes 23. When the wire is wound, when the wire jumps relative to the push limit hook 8, when the jump wire enters the guide slope 23, the guide slope 23 facilitates the wire to return to its original position relative to the wire cutting plate 1. The two push limit hooks 8 are provided with a middle notch, which is adapted to the telescopic blade 10 and provides an insertion port for the telescopic blade 10 to enter, so that the telescopic blade 10 can contact the cutting plane 11.

[0028] A winding machine includes a main frame 24, a turntable 25 mounted on the main frame 24, two electrically powered winding support tubes 26 mounted on the turntable 25, two shaving plates 1 fixedly connected to the front end of the turntable 25, and the two shaving plates 1 and the two electrically powered winding support tubes 26 are arranged alternately at intervals. Each shaving plate 1 is fixedly connected to a mounting plate 27, and the two mounting plates 27 are fixedly connected to the turntable 25 by multiple connecting bolts 28. The two shaving plates 1 are centrally symmetrically arranged on the turntable 25 to form a continuous winding operation of the filament. During the operation, the overall continuity is good, the operation efficiency is high, and it is more practical.

[0029] In this embodiment, the servo motor 3, main frame 24, turntable 25, and electric winding support tube 26 are all commercially available conventional equipment known to those skilled in the art. In this invention, we only use them without making any improvements to their structure and function. Their setting method, installation method, and electrical connection method can be easily explained by those skilled in the art by following the instructions for use. Therefore, we will not elaborate on them here.

[0030] In summary, the working principle of this easy-to-change wire cutting device and winding machine is as follows: First, the easy-to-change wire cutting device is installed on the corresponding winding machine, and the servo motor 3 is electrically installed. During actual operation, two electric winding support tubes 26 are used to mount the core cylinder for winding the wire. The electric winding support tubes 26 can provide internal support and positioning for the mounted core cylinder. The electric winding support tubes 26 have an electric self-rotation function to achieve the rotation of the core cylinder, thus achieving the winding motion of the wire relative to the core cylinder. Before the wire is wound, the turntable 25 will be positioned relative to the main frame 2. 4. Adjust the angle appropriately so that the slicing plate 1 and the electric winding support tube 26 are positioned with the slicing plate 1 at a higher relative position and the electric winding support tube 26 at a lower relative position. Before the wire is wound onto the core cylinder, it will be guided by the higher-positioned slicing plate 1. After the wire is wound relative to the core cylinder, the turntable 25 will work to exchange the positions of the two core cylinders. The rotation adjustment direction of the turntable 25 is to move the core cylinder that is winding the wire away from the direction from which the wire came, so that another core cylinder that has not yet been wound with wire can be connected to the wire winding position. After that, the unwound core cylinder will be wound. The core cylinder of the wire compresses the wire, and the servo motor 3, corresponding to the electric winding support tube 26 after winding, rotates the lead screw 2, causing the slide 4 to move forward relative to the cutting plate 1. The forward movement of the slide 4 drives the corresponding push limit hook 8 to move forward synchronously, bringing the cutting plane 11 closer to the telescopic blade 10. When the slide 4 contacts the push connecting plate 22, the continued forward movement of the slide 4 pushes the push connecting plate 22 to form a relative forward displacement relative to the end frame 9. This is achieved through the drive shaft 18, driven shaft 20, and fixed... Under the combined action of the fixed ear 21, the push connecting plate 22 and the linkage frame 13, the forward-moving slide 4 will cause the telescopic blade 10 to move backward, thereby achieving the extension of the telescopic blade 10 from the end frame and its contact with the cutting plane 11, thus achieving the cutting of the wire between the telescopic blade 10 and the cutting plane 11. After the wire is cut, the core cylinder that has not yet wound the wire rotates to achieve the rewinding of the wire, while the core cylinder that has finished winding the wire loses the internal tensioning effect of the corresponding electric winding support tube 26 by controlling it, so as to facilitate the removal of the core cylinder and the wire on it.
