Description

Technical Field

[0001] This invention relates to the field of circular knitting machine weaving equipment technology, and in particular to a graded clamping and adjusting device for an artificial fur machine. Background Technology

[0002] An artificial fur knitting machine is a single-sided weft circular knitting machine used for weaving weft-knitted plush fabrics. In addition to a yarn guide for feeding the ground yarn, this machine also has a sliver feeding device that feeds the sliver through upper and lower rollers into a doffer with a surface covered in metal combs. The knitting needles rise and hook the fiber bundles attached to the doffer's surface, weaving them together with the ground yarn into the fabric to create a plush effect similar to natural fur.

[0003] Currently, during the operation of circular knitting machines, the weaving of fiber raw materials (such as polyester, nylon, wool, etc.) requires traction and crimping to achieve certain appearance and performance requirements. In particular, for product fabrics that require unwinding tension or traction and crimping, a traction and crimping device is used to clamp and remove them from the machine. Examples include knitted fabrics, sportswear, underwear, and other fabrics that require elasticity and softness, as well as thicker and stiffer fabrics such as artificial fur and leather.

[0004] Existing circular knitting machines typically employ a curling roller for pulling and holding the fabric. A motor drives the roller to rotate, thus pulling the fabric up. However, the required tension and gripping force vary significantly depending on the fiber thickness, elasticity, and fabric thickness. Therefore, fabrics pulled and curled by the curling roller often suffer from poor uniformity and smoothness. This is especially true for artificial fur machines. Because artificial fur requires thicker and fluffier yarns, the tension exerted by the curling roller after weaving directly affects the fabric's surface quality, texture, and fluffiness. Therefore, improving the pulling and curling device of artificial fur machines is crucial.

[0005] To address the aforementioned issues, Chinese Patent CN102344049A discloses a winding device for a fur knitting machine. This device includes a winding roller mounted on the frame and a pair of guide rollers. The guide rollers are positioned above the take-up roller at the lower end of the knitting cylinder, with the take-up roller located below the center of the two guide rollers. This patent uses a pair of guide rollers at the lower end of the knitting cylinder to guide and pre-press the knitted fabric before it is wound up by the take-up rollers, resulting in a smooth and uniform fabric. However, this method only enhances the tension and clamping effect on the fur fabric and does not effectively improve the problem of uneven tension on the fabric surface. Furthermore, in actual production, the speed and tightness of the clamping device are often controlled by professionals based on their experience and estimations to obtain better quality artificial fur fabric, but inevitably, the fabric products suffer from serious quality deviations and batch variations. Summary of the Invention

[0006] To address the aforementioned problems, the present invention aims to provide a grading clamping and adjusting device for an artificial fur machine, comprising two main components: a clamping device and a grading and adjusting device.

[0007] The clamping device includes a set of symmetrical clamping components, each consisting of a q-shaped column and a pulling rod that cooperate with each other. The pulling rod is located below the q-shaped column. On the other side of the symmetrical structure is a p-shaped column and a corresponding pulling rod. The clamping components clamp the fur by cooperating with the q-shaped column (p-shaped column) and the corresponding pulling rod. The column structure of the clamping component includes a detachable cylindrical component, a pin, and columns that are detachable at both the top and bottom. The grading adjustment device includes a grading adjustment rod, a counterweight, and a counterweight placement slot. In one embodiment, the top and bottom ends of the q-shaped column and p-shaped column in the clamping component are detachable rounded columns, which can improve the contact force of the fur at that location.

[0008] In one embodiment, the surfaces of the q-shaped and p-shaped cylinders in the clamping device are each composed of three arc curves (R1, R2, R3), and the radius of the pulling rod is R4. The three arc curves are R1 (a semi-circular arc), R2 (a quarter-circular arc), and R3 (a quarter-circular arc), and the surface dimensions of the clamping device are in a fixed relationship with the diameter of the pulling rod: 2R4 > R1 > R2 > R4 > R3.

[0009] In one embodiment, the length of the cylindrical component of the clamping device can be increased or decreased according to the actual diameter of the artificial fur machine and the shrinkage rate of the fur, so as to achieve appropriate size control of the clamping device.

[0010] In one embodiment, the surface of the clamping device is made of a smooth metal material to reduce the pulling and tearing damage to the fur.

[0011] In one embodiment, two clamping components with symmetrical structures are connected and fixed by two sets of graded adjustment devices in the middle; one set of graded adjustment rods is located on the horizontal plane of the center of the R1 arc area in the clamping device, and the other set of graded adjustment rods is located on the horizontal plane of the center of the pulling rod.

[0012] In one embodiment, a graded adjustment rod connected to the clamping device is provided in a direction perpendicular to the axis of the clamping device. The graded adjustment rod can be rotated left and right to adjust the distance from the curved surface of the R2 arc region of the clamping device to the pulling rod.

[0013] In one embodiment, the grading adjustment device adjusts the weight of the counterweight so that the vertical clamping force F1 of the clamping device R1 region on the fur is equal to the horizontal clamping force F2 of the clamping device R2 region on the fur after the adjustment of the adjusting rod.

[0014] In one embodiment, the length of the counterweight and the depth of the counterweight placement groove are both equal to the diameter of the pulling rod, and the center of the counterweight is located above the center of the pulling rod.

[0015] In one implementation, the position of the grading adjustment rod is adjusted according to the actual usage. If it is a very thick fur, the grading adjustment rod is located diagonally above the horizontal plane of the center of the pulling rod. At this time, the counterweight is adjusted first to increase the weight, the fur is pressed down, and the adjustment rod is lowered to the horizontal plane of the center. Then the grading adjustment rod is adjusted again, and the grading adjustment rod is extended and retracted so that the distance D is equal to the fabric thickness after the counterweight is adjusted.

[0016] In one embodiment, the adjustment levels of the adjusting rod are related to the weight of the counterweight as follows: Level 1 corresponds to weight 4, with a fur thickness of x1; Level 2 corresponds to weight 3, with a fur thickness of x2; Level 3 corresponds to weight 2, with a fur thickness of x3; and Level 4 corresponds to weight 1, with a fur thickness of x4. Here, x1, x2, x3, and x4 represent different fur thicknesses, arranged in descending order of thickness: x4>x3>x2>x1. This tiered adjustment device configuration allows for clamping and adjustment of furs of different thicknesses across four levels.

[0017] The beneficial effects of the present invention are:

[0018] The graded clamping adjustment device for an artificial fur machine provided by this invention can precisely control the clamping tension of the artificial fur machine to cope with fur fabrics of different thicknesses and quality requirements by adjusting the relationship between the graded adjustment device and the counterweight, and by matching the reasonable advantages of the clamping device's shape and surface. Different grades can be adjusted by adjusting the graded adjustment rod to provide uniform, graded, and strong clamping action for the clamping device, reducing waste caused by uneven fabric thickness or uneven surface, and significantly improving the production efficiency and product quality of the artificial fur machine. In addition, this device requires very little modification to the original artificial fur machine's curling device. It only requires clamping and installing a graded clamping adjustment device on the original artificial fur machine's curling roller. Moreover, the installation, disassembly, and adjustment of this device are convenient and labor-saving. Attached Figure Description

[0027] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] This embodiment provides a graded clamping and adjusting device for an artificial fur machine, comprising two main components: a clamping device and a graded adjusting device. The clamping device provides sufficient and uniform clamping force on the fabric surface, ensuring the smoothness of the fabric during fur production. The graded adjusting device, through graded settings, effectively addresses the clamping situation of fur of different thicknesses after unloading, achieving good clamping performance for artificial fur of varying thicknesses and quality requirements. This graded clamping and adjusting device for an artificial fur machine provides uniform, graded, and strong clamping action, significantly improving the production efficiency and product quality of the artificial fur machine.

[0030] The clamping device includes a set of symmetrical clamping components, such as... Figure 1 As shown, Figure 1 (a) is a schematic diagram of the structure of the graded clamping and adjusting device and the pulling rod. Figure 1 (b) is a plan view of the graded clamping and adjusting device and the pulling rod structure. Figure 1 (c) in the diagram is a cross-sectional schematic of the graded clamping and adjusting device; as shown in the image. Figure 1As shown in (a), the symmetrically structured graded clamping and adjusting device is located on the upper part of the pulling rod, and achieves clamping through cooperation with the pulling rod; as Figure 1 As shown in (b), the length of the clamping column is L1, the length of the pulling rod is L2, and r represents the radius of the rounded corner portion of the detachable rounded corner column; as shown in (b). Figure 1 As shown in (c), the q-type clamping component 1 and p-type clamping component 2, which are symmetrical to each other in the graded clamping adjustment device, are fixedly connected by the internal graded adjustment rod 3.

[0031] The detailed structure of the clamping component is as follows: Figure 2 As shown, Figure 2 (a) is a schematic diagram of the surface structure of the clamping component. Figure 2 (b) is a detailed structural diagram of the detachable rounded corner cylinder of the clamping component after disassembly. Figure 2 (c) in the diagram is a schematic diagram of the disassembly process of the detachable column at the edge of the clamping component; as shown in Figure 1. Figure 2 As shown in (a), the edge of the clamping component is a detachable rounded cylindrical structure, which can improve the contact force of the fur at that location; Figure 2 As shown in (b), the detachable rounded cylinder is secured to the clamping component by a pin; as Figure 2 As shown in (c), the length of the grading clamping device can be adjusted according to the actual use. The detachable rounded column 13 is fixed to the grading clamping adjustment device by the pin 12. When it is necessary to change the length of the grading clamping adjustment device, the detachable rounded column 13 can be removed, the detachable cylindrical component 11 can be installed on the pin 12, and then the detachable rounded column 13 can be fixed back to the clamping component to realize the change of the clamping component length. This measure can not only play a certain role in expanding the distribution, but also provide a more uniform and suitable clamping effect for products with different fur machine cylinder diameters and artificial fur with different shrinkage effects. It should be noted that the length L1 of the clamping column is less than the length L2 of the pulling rod. Even if the length L1 of the clamping column is greater than the length L2 of the pulling rod, the part of the clamping column that is longer than the pulling rod will not produce a clamping effect.

[0032] The clamping device, as the core component of the system, needs to be effective for handling fur of varying thicknesses. The surface dimensions of the clamping device are fixed to the diameter of the pulling rod, and the surface dimensions of the clamping device consist of three arc curves (R1, R2, R3), while the radius of the pulling rod is R4. For example... Figure 3 As shown; where, Figure 3 (a) in the diagram is a cross-sectional view of the clamping component. Figure 3 (b) is a magnified schematic diagram of the three arc curves and the pulling rod in the clamping component; as shown in Figure (b). Figure 3As shown in (b), the three arc curves are R1 (semi-circular arc curve), R2 (1 / 4 arc curve), and R3 (1 / 4 arc curve). The length relationship between the radius of the three arc curves and the radius of the pulling rod is 2R4 > R1 > R2 > R4 > R3 to ensure a better clamping effect. In addition, the surface of the clamping component is made of smooth metal material to reduce the clamping and pulling damage to the fur.

[0033] The grading adjustment device includes a grading adjustment rod, a counterweight, and a counterweight placement slot; such as Figure 4 As shown, the grading adjustment device includes a grading adjustment rod 3, a counterweight 4, and a counterweight placement groove 5. The grading adjustment rod 3, perpendicular to the axial direction of the clamping device, connects to the symmetrical clamping device. The grading adjustment rod 3 can be adjusted in length by rotating left and right, thereby adjusting the distance from the curved surface of the clamping device's R2 region to the pulling rod. The counterweight 4 is placed in the counterweight placement groove 5 between the grading adjustment rods 3. The clamping action is achieved through the adjustment action of the grading adjustment rods 3 in conjunction with the curved surface of the clamping device and the pulling rod. The counterweight can be loaded and unloaded by adjusting the grading adjustment rods 3.

[0034] The working principle of the graded adjustment device is as follows: Figure 5 As shown, where, Figure 5 (a) in the diagram is a detailed cross-sectional view of the device. Figure 5 (b) in the diagram is a schematic diagram showing the relationship between the grade and the spacing between the clamping column and the pulling rod during the grade adjustment process; for example... Figure 5 As shown in (a), the grading adjustment rod 3 is located on the horizontal plane of the center of the R1 arc region and the horizontal plane of the center of the pulling rod, respectively; the length of the counterweight 4 is L3, located on the horizontal plane of the center of the R1 arc region; the distance between the clamping column and the pulling rod is D; the vertical clamping force acting on the fur in the R1 arc region is F1, and the horizontal force acting on the fur in the R2 arc region is F2; ​​by adjusting the grading adjustment rod 3, the vertical force F1 and the horizontal force F2 are made equal; and the number of grading adjustment rods 3 and the size of the counterweight 4 can also be adjusted according to the actual use to ensure that the vertical force F1 and the horizontal force F2 are equal; the L3 of the counterweight 4 and the depth of the counterweight placement groove 5 are both equal to the diameter of the pulling rod (2R4), and the center of the counterweight 4 is located above the center of the pulling rod. Figure 5 As shown in (b), when the adjustment level is four, the distance between the clamping component and the pulling rod is D. The adjustment level is adjusted to one by the grade adjustment rod 3, and the length of the grade adjustment rod 3 increases, thereby reducing the distance D between the clamping component and the pulling rod, thus realizing the adjustment of the fur clamping force.

[0035] Place Figure 6As shown, the relationship between the adjustment levels of the grading adjustment rod (3) and the weight of the counterweight (4) is as follows: Level 1 corresponds to weight 4, and the corresponding fur thickness is x1; Level 2 corresponds to weight 3, and the corresponding fur thickness is x2; Level 3 corresponds to weight 2, and the corresponding fur thickness is x3; Level 4 corresponds to weight 1, and the corresponding fur thickness is x4; where x1, x2, x3, and x4 represent different fur thicknesses, and the order of thickness from largest to smallest is x4>x3>x2>x1. The configuration and adjustment relationship of the grading adjustment device can meet the clamping adjustment of furs of different thicknesses in 4 levels.

[0036] Based on this, the graded clamping adjustment device for artificial fur machines provided by the present invention can precisely control the clamping and pulling force of artificial fur machines by adjusting the relationship between the graded adjustment device and the counterweight, as well as by using the reasonable and advantageous shape and surface of the clamping device, to provide uniform, graded, and strong clamping action, reduce waste caused by uneven fabric thickness or uneven surface, and significantly improve the production efficiency and product quality of artificial fur machines.

[0037] In this embodiment, a fur fabric with a thickness of approximately 10mm after unloading is used to verify the clamping and pulling effect of the device proposed in this invention. The fur fabric becomes fluffy after being unloaded, so its thickness on the machine is much greater than 10mm. The distance (D) from the curved surface of the clamping device R2 area to the pulling rod should also be less than 10mm. Based on this, the adjusting rod 3 of the grading adjustment device can be adjusted so that the distance (D) from the curved surface of the clamping device R2 area to the pulling rod is 5-7mm. Simultaneously, the counterweight 4 of the grading adjustment device is set to around 500g, ensuring that the center of the counterweight 4 is above the center of the pulling rod, and that the lower two of the four adjusting rods 3 are at the same level as the center of the pulling rod. This embodiment, based on the grading clamping and pulling device for an artificial fur machine provided by this patent, improves the uniformity of fabric thickness and surface flatness, thereby increasing the production efficiency and product quality of the artificial fur machine.

[0038] Some steps in the embodiments of the present invention may be implemented using software, and the corresponding software program may be stored in a readable storage medium, such as a CD or a hard disk.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
