Description

Technical Field

[0001] The utility model relates to the technical field of knotting machines, and more particularly to a rope-twisting and knotting machine for processing fiber scarves. Background Art

[0002] Scarf is an indispensable fabric in people's daily life. There are three processing methods for it: weaving, knitting and hand-knitting. In the process of production, in order to make the scarf more beautiful, some weft yarns are usually reserved at the end of the scarf, and these weft yarns are made into rope-like tassels and then knotted. However, the current rope twisting and knotting equipment is not suitable for production.

[0003] Chinese patent application No. CN202020696144.6 discloses a rope-twisting and knotting machine for scarf processing, including a rope-twisting and knotting machine body, a fixing mechanism and a rolling mechanism. The surface of the rope-twisting and knotting machine body is connected to a processing panel, and the fixing mechanism includes a fixing block, which is fixedly connected to a stop block on one side surface of the rope-twisting and knotting machine body. A spring is connected to the other side surface of the spring, and a stop plate is connected to the bottom end surface of the stop plate. A non-slip pad is provided, and a pull rod is provided inside the stop block. Through the designed fixing mechanism, the scarf can be fixed on the processing panel in a stable state, and knotting work can be performed stably. At the same time, the scarf product can be quickly replaced by manual pulling, which speeds up the production and processing of the scarf. The non-slip pad contacts the surface of the scarf, which can also prevent the scarf thread from sliding, and at the same time avoid the corners of the equipment from hooking the scarf, thereby playing a protective role.

[0004] When the above solution is implemented, the scarf is rolled up by the winding mechanism and one end of the scarf is fixed by the fixing mechanism. Since most scarves have a symmetrical structure, both ends of the scarf need to be knotted. After the knot is tied at one end, when replacing the other end, the scarf needs to be removed first, and then fixed and rolled up after switching one end. The entire device is relatively cumbersome for disassembling and installing the scarf, which increases the workload of workers and reduces work efficiency. A solution is proposed below to address the above problems. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a rope twisting and knotting machine for processing fiber scarves, which can quickly convert the two ends of the scarf and improve work efficiency.

[0006] In order to solve the above problems, the present invention adopts the following technical solutions.

[0007] A rope twisting and knotting machine for processing fiber scarves includes a knotting machine body, a processing surface is provided at the processing end of the knotting machine body, a telescopic bracket is provided on the processing surface, a fixed frame is provided on one side of the telescopic bracket, two winding rods are provided inside the fixed frame, and the two winding rods are respectively slidably matched with the fixed frame, and a driving assembly for driving the two winding rods to move is provided on one side of the fixed frame, the two winding rods are located at both ends of the side of the fixed frame, and the two winding rods are at different heights, and clamping assemblies are respectively provided at both ends inside the fixed frame, and the clamping assemblies are respectively matched with the upper and lower end surfaces inside the fixed frame.

[0025] Example 1:

[0026] See also Figure 1-6A rope twisting and knotting machine for processing fiber scarves includes a knotting machine body 1. A controller 16 is fixedly connected to the side of the knotting machine body 1. The controller 16 is used to control the start and stop of subsequent components and plays a control role. The processing end of the knotting machine body 1 is provided with a processing surface 2. A telescopic bracket 3 is provided on the processing surface 2. The telescopic bracket 3 includes a bottom end and a moving end. The bottom end is fixed on the processing surface 2. The moving end passes through the top of the bottom end and slides together. A second cylinder 13 is provided on one side of the telescopic bracket 3. The second cylinder 13 is electrically connected to the controller 16. The bottom processing surface 2 of the second cylinder 13 is fixed. The output end of the second cylinder 13 and the movable end of the telescopic bracket 3 are fixedly connected. The extension and retraction of the second cylinder 13 can drive the telescopic bracket 3 to extend and retract. After the telescopic bracket 3 is extended, it can drive the fixed bracket 4 to move upward, thereby separating from the processing surface 2 and creating a distance, which is convenient for rotating the fixed bracket 4 and avoiding limitation, and realizing the conversion of the two ends of the scarf. At the same time, when the second cylinder 13 is retracted, the telescopic bracket 3 can be driven to retract, and the fixed bracket 4 directly acts on the processing surface 2, which is convenient for the knotting machine body 1 to process the scarf and ensures the stability of the knotting machine body 1 when processing the scarf.

[0027] The upper and lower end surfaces of the fixing frame 4 are both provided with stabilizing buffer pads 15, which are used to buffer the contact between the fixing frame 4 and the processing surface 2 when the fixing frame 4 rotates, so as to avoid generating large noises. At the same time, the processing surface 2 and the fixing frame 4 are both protected. The fixing frame 4 is fixedly connected to a rotating shaft on one side near the moving end, and the rotating shaft passes through the moving end and rotates to achieve the rotational cooperation between the fixing frame 4 and the moving end, that is, the conversion of the two ends of the scarf inside the fixing frame 4 can be adjusted by rotating the fixing frame 4, and the scarf does not need to be removed and reinstalled, which is convenient for conversion and can improve efficiency. The cross section of the fixing frame 4 is C-shaped, and the C-shaped design can facilitate the scarf to be put into and taken out of the fixing frame 4. The interior of the fixing frame 4 is fixedly provided with a vertical plate, and the vertical plate is horizontally provided with two slide grooves, and the two slide grooves are at different levels. The side of the fixing frame 4 will have a stabilizing groove corresponding to the two slide grooves. The cam 5 is fixedly connected to the outside of the reel 5 and is fixed with a stopper 14 to prevent the reel 5 from separating from the stopper 14 and the reel 5.

[0028] Clamping assemblies 7 are respectively provided at both ends of the interior of the fixing frame 4. The two clamping assemblies 7 respectively cooperate with the upper and lower end surfaces inside the fixing frame 4. The clamping assembly 7 includes a first cylinder 11 and a pressure plate 12. The first cylinder 11 is vertically arranged inside the fixing frame 4. The first cylinder 11 and the controller 16 are electrically connected, and the pressure plate 12 is horizontally arranged at the output end of the first cylinder 11. The pressure plate 12 is pushed to move by the first cylinder 11, and the end of the scarf is clamped by the pressure plate 12 and the fixing frame 4. The use of two clamping assemblies 7 can facilitate the fixation of the two ends of the scarf, ensuring that the end of the scarf is in a fixed position after changing direction, which is convenient for the knotting machine body 1 to perform knotting operations.

[0029] A driving assembly 6 is provided between the fixed frame 4 and the vertical plate. The driving assembly 6 includes a motor 8, a gear 9 and a rack 10. The motor 8 is fixed on one side of the fixed frame 4. The motor 8 and the controller 16 are electrically connected. The gear 9 is fixed at the output end of the motor 8. The two slides are symmetrical and fixedly connected with slide rails. The slide rails and the slides are parallel to each other. There are two racks 10. The two racks 10 slide with the two slide rails respectively, and the two racks 10 are symmetrical between the centers. The gear 9 is arranged between the two racks 10, and the two racks 10 are meshed with each other. The two racks 10 are fixedly connected to the corresponding moving rods respectively. The gear 9 is driven to rotate by the motor 8, and the two racks 10 are driven to move by the gear 9, thereby driving the two moving rods to move in opposite directions through the rack 10, that is, driving the winding rod 5 to move in opposite directions, which can avoid manual pulling of the winding rod 5, automate the operation, and reduce the labor intensity of manual labor.

[0030] Working principle:

[0031] When in use, the user places the scarf inside the fixing frame 4, with the two ends of the scarf respectively located between the winding rod 5 and the fixing frame 4, and the middle part of the scarf located between the two winding rods 5. At the same time, the two ends of the scarf are respectively arranged between the two clamping plates and the fixing frame 4. The controller 16 controls the first cylinder 11 to start, and the first cylinder 11 drives the clamping plate to move, thereby radially fixing the ends of the scarf through the clamping plate and the fixing frame 4, ensuring the stability of the scarf when the scarf is processed by the subsequent knotting machine, and avoiding damage to the scarf.

[0032] After the two ends are clamped and fixed, the controller 16 will control the motor 8 to start, the motor 8 will drive the gear 9 to rotate, and the gear 9 will drive the mutually meshing racks 10 to move. Since the rack 10 is restricted by the guide rail, the rack 10 will move along the guide rail, and the rack 10 will drive the moving rod to move. The movement of the moving rod will drive the scarf to bend and straighten, so that the scarf will bend into a Z shape, which has a storage effect on the scarf, and then the end of the scarf will be knotted through the knotting machine body 1.

[0033] When one end is knotted, the controller 16 controls the second cylinder 13 to start, and the second cylinder 13 will drive the telescopic bracket 3 to start, and the telescopic bracket 3 will drive the fixing bracket 4 to move upward, that is, drive the fixing bracket 4 and the processing surface 2 to separate. The user rotates the fixing bracket 4, and the fixing bracket 4 will drive the internal scarf to rotate, that is, rotate the other end of the scarf to the processing end of the knotting machine body 1, so that the knotting machine body 1 can process the other end of the scarf. After the conversion is completed, the controller 16 drives the second cylinder 13 to retract, so that the fixing bracket 4 falls on the processing surface 2 to ensure stability during processing. Until the other end is also processed, the controller 16 controls the motor 8 to reverse, thereby driving the winding rod 5 to loosen the scarf, and then controls the first cylinder 11 to retract through the controller 16, and removes the clamping plate to clamp the end of the scarf, so that the scarf can be taken out and replaced with a new scarf.
