Description

Technical Field

[0001] The utility model relates to the technical field of installation and debugging of combing machine nippers, and particularly discloses a combing machine nipper pressure measuring device. Background Art

[0002] Combing machines are crucial pieces of equipment in the textile industry, and one of their core components is the nipper system. This system not only plays a key role in improving yarn quality and removing short fibers and impurities, but also directly impacts spinning efficiency and the quality of the final product. A combing machine's nipper system typically consists of two nippers, upper and lower, which work together to periodically open and close during machine operation to achieve precise control of the fiber bundle. Each set of nippers consists of multiple fingers (or jaws), typically made of high-strength, wear-resistant materials.

[0003] The nippers of a comber play a crucial role in inserting, gripping, and pulling fibers. Nip pressure is a key parameter influencing fiber pulling, so properly adjusting nipper pressure is crucial for improving fiber quality and processing results. Over time, combing equipment can experience significant variations in pressure between different nipper fingers, leading to poor combing results.

[0004] Currently, to address this issue, experienced and skilled maintenance personnel are often required to adjust the nipper pressure by adjusting the tension shaft and the spring compression in the guide rod according to the fiber pulling conditions and the web bonding conditions. However, manual adjustment of the nipper pressure cannot guarantee balanced pressure at different nipper fingers, which still affects the carding quality of the finished product. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the present invention provides a combing machine nipper pressure measuring device to solve the problem that when relying on manual experience to adjust the pressure, the pressure at the nipper fingers cannot be guaranteed to be balanced, which still affects the combing effect of the finished product.

[0006] In order to achieve the above purpose, the technical solution of the utility model is:

[0007] A combing machine nipper pressure measuring device comprises a digital spring scale and a turnbuckle. A screw at one end of the turnbuckle is connected to the digital spring scale via a connector. A first hook is fixedly mounted on the screw end of the other end of the turnbuckle. A second hook is connected to the pull rod of the digital spring scale. The second hook is connected to a mounting member for mounting the combing machine frame. During use, the first hook is attached to the tension shaft at different nipper fingers, and the mounting member is attached to the combing machine frame. The digital spring scale reading is used to adjust the compression of the springs in the tension shaft and guide rod, thereby reducing the pressure difference between different nipper fingers. This makes the nipper pressure adjustment process more intuitive, reduces the requirements for maintenance personnel, and improves the combing effect of the finished product.

[0008] Preferably, the connector includes a concave-shaped connecting frame; the two side walls of the connecting frame are hingedly connected to the two side walls of the digital spring scale; a through hole is provided on the bottom surface of the connecting frame; the screw rod of the turnbuckle passes through the through hole and is fixed to the connecting frame by two nuts. The provision of the connector can make the reading of the digital spring scale more stable.

[0009] Preferably, the mounting member includes a fixed plate; a side hanging plate is telescopically mounted on the fixed plate; and a limit assembly is provided between the fixed plate and the side hanging plate. The side hanging plate can be extended and retracted on the fixed plate, the distance between the side hanging plate and the fixed plate can be adjusted, and the side hanging plate is fixed by the limit assembly, thereby facilitating mounting on the frame of different types of combing machines and ensuring stable mounting.

[0010] Preferably, the fixed plate includes a horizontal plate; a plurality of insertion rods are provided on the upper side of the horizontal plate; the plurality of insertion rods are arranged at intervals and parallel to each other; a plurality of clearance grooves are provided on the hanging side plate; the insertion rods are inserted into the clearance grooves; the limiting assembly includes two bolts; the fixed plate and the hanging side plate are connected by two bolts.

[0011] Preferably, the hanging plate further comprises a flat plate; a clearance groove is provided on the flat plate; and a folded plate is fixedly provided at one end of the flat plate away from the clearance groove. When the hanging member is hung on the comber frame, the lower portions of the folded plate and the side surface of the cross plate respectively contact the two side surfaces of the comber frame crossbeam, thereby ensuring stable hanging and accurate readings of the digital spring scale.

[0012] Preferably, the hem plate is provided with anti-slip grooves to increase friction and ensure stable hanging.

[0013] The beneficial effects of the utility model are as follows: when in use, a hook is used to hang on the tension shaft at different pliers fingers, which is then hung on the combing machine frame using a hanging piece, and the digital spring scale reading is used to adjust the compression amount of the spring in the tension shaft and the guide rod, thereby reducing the pressure difference at different pliers fingers, making the pressure adjustment process of the pliers plate more intuitive, reducing the requirements on the quality of maintenance personnel, and improving the combing effect of the finished product.

[0021] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0022] like Figure 1-3 As shown, a combing machine nipper pressure measuring device includes a digital display spring scale 1 and a basket bolt 2. The basket bolt 2 is open. The end of the screw at the upper end of the basket bolt 2 is fixedly provided with a hook 3, which is used to hang on the tension shaft of the nipper. The screw at the lower end of the basket bolt 2 is connected to the digital display spring scale 1 through a connector 5.

[0023] In this embodiment, the connector 5 includes a connecting frame 501 that is generally concave in shape. Reinforcing ribs 502 are provided between the side walls and bottom surface of the connecting frame 501 to enhance structural rigidity. The side walls of the connecting frame 501 are hinged to the side walls of the digital spring scale 1, allowing the turnbuckle 2 to rotate on the digital spring scale 1, increasing the adjustment space during use and broadening its applicability. A through hole is provided on the bottom surface of the connecting frame 501. The screw at the lower end of the turnbuckle 2 passes through the through hole and is fixed to the connecting frame 501 via two nuts. The provision of the connector can ensure more stable readings on the digital spring scale. In alternative embodiments, a threaded sleeve is provided on the outer wall of the digital spring scale 1, and the screw at the lower end of the turnbuckle 2 is threaded within the sleeve. This results in a rigid and fixed connection between the digital spring scale 1 and the turnbuckle 2, limiting the adjustment space during use.

[0024] In the above arrangement, a radial through hole is provided on the pull rod 101 of the digital display spring scale 1, and a hook 2 4 is connected to the radial through hole; the hook 2 4 is connected to a hanging member for hanging the combing machine frame. The hanging member includes a fixed plate 6; the fixed plate 6 includes a horizontal plate 601; eight plug rods 602 are provided on the upper side of the horizontal plate 601; the eight plug rods 602 are arranged at intervals and parallel to each other; the hanging plate 7 includes a flat plate 702; eight clearance grooves 701 are provided on the flat plate 702 to match the plug rods 602, and the plug rods 602 are inserted into the clearance grooves 701, so that the hanging plate 7 can be extended and retracted on the fixed plate 6; the clearance grooves 701 are extended inward from the side wall of the flat plate 702. In order to fix the position of the hanging plate 7 on the fixed plate 6, a limiting assembly is provided between the fixed plate 6 and the hanging plate 7. The limiting assembly includes two bolts 8; the fixed plate 6 and the hanging plate 7 are connected by two bolts 8. Three first through holes are provided along the width direction of the flat plate 702, and three second through holes are provided along the width direction of the insertion rod 602. Bolts 8 can be provided through the first through holes and the second through holes. Two bolts 8 are used to fix the side hanging plate 7 to the fixed plate 6. The length of the hanging member can be adjusted according to different carding machine models to ensure stable hanging. In other alternative embodiments, when the limit assembly is provided, through holes are provided along the length direction of the side hanging plate 7 and the fixed plate 6. Bolts 8 are provided in the through holes, and nuts are provided at the ends of the bolts 8. A shim is placed between the bottom surface of the clearance groove 701 and the insertion rod 602 to fix the length of the hanging member and fix the side hanging plate 7 to the fixed plate 6.

[0025] A hemmed plate 703 is fixedly mounted on the end of the flat plate 702, away from the clearance slot 701. Anti-slip grooves 704 are provided on the hemmed plate 703 to increase friction and ensure stable mounting. When the mounting member is mounted on the comber frame, the hemmed plate 703 and the lower portion of the side of the cross plate 601 contact the two side surfaces of the comber frame beam, respectively, ensuring stable mounting and accurate readings on the digital spring scale 1.

[0026] In other alternative embodiments, the hanging member is an integral part, and the cross section is concave-shaped. When measuring the pressure of the nippers of combers of different models, the hanging member is replaced according to the model of the comber.

[0027] When in use, close the nipper plate, use hook 3 to hang it on the tension shaft at different nipper fingers, use the folding plate 703 and the lower part of the side of the cross plate 601 to contact the two side surfaces of the combing machine frame crossbeam respectively, hang the hanging part on the crossbeam of the combing machine frame, use the digital spring scale 1 to read the value, adjust the compression amount of the spring in the tension shaft and the guide rod, reduce the pressure difference at different nipper fingers, make the pressure adjustment process of the nipper plate more intuitive, reduce the quality requirements for maintenance personnel, and improve the combing effect of the finished product.

[0028] Before using this comber nipper pressure measuring device, there were significant differences in pressure between combers and between different nipper fingers on a single comber, with the maximum difference reaching more than 10 kg. The nippers of a single comber had uneven grip, resulting in uneven combing effects, which led to fiber damage. Especially when producing high-quality long fibers (≥16 mm), this easily caused material loss and unnecessary consumption.

[0029] The use of this comber nipper pressure measurement device not only provides precise readings of nipper pressure but also enables the development of standardized specifications for different comber models. Through meticulous machine-by-machine and nipper-by-finger testing and comparison, precise control and standardization of nipper pressure across the same model and within individual machines has been successfully achieved. Comber noil has decreased by an average of 0.2%, significantly saving production costs. For example, with three teams operating at 12 tons per day, this results in a 24kg reduction per shift, a 24kg*3=72kg reduction per day, a 2,160kg reduction per month, and a 25,920kg reduction per year. At 17,000 RMB per ton of raw cotton, this translates to an annual saving of 440,640 RMB in raw cotton costs.

Without departing from the spirit and essence of the present invention, persons of ordinary skill in the art may make various equivalent modifications or substitutions to the embodiments of the present invention, and such modifications or substitutions shall be within the scope of the present invention. Any changes or substitutions that can be easily conceived by persons skilled in the art within the technical scope disclosed in the present invention shall be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
