Description

Technical Field

[0001] The invention relates to the technical field of circular knitting machine weaving equipment, in particular to a graded clamping and adjusting device on an artificial fur machine. Background Art

[0002] Artificial fur machine is a single-sided weft knitting circular machine used for weft knitting long plush fabrics. In addition to the yarn guide for feeding the ground yarn, this machine also has a set of wool strip feeding device, which can feed the wool strips into the doffer covered with metal combing needles through the upper and lower rollers. After the knitting needles rise and hook the fiber bundles attached to the doffer surface, they are woven into the fabric together with the ground yarn to form a fluffy effect similar to natural fur.

[0003] At present, during the working process of circular knitting machines, fibers (such as polyester, nylon, wool, etc.) and other yarn materials need to be pulled and curled before they can meet certain appearance and performance requirements. In particular, for products that require tension or pulling and curling, the grey fabrics will be clamped and unloaded through the pulling and curling device, such as knitted fabrics, sportswear, underwear and other product fabrics that require elasticity and softness, or thicker and stiffer fabric products such as artificial fur and leather.

[0004] The pulling, curling and clamping devices of existing large circular knitting machines are mostly curling rollers, which are driven by motors to rotate, so that the fabric is rolled up and pulled down. However, for fibers of different thicknesses or different elasticities, and fabrics of different thicknesses, the required pulling, curling and clamping tension and holding force are completely different, so the fabric obtained by curling the curling rollers will have problems of poor uniformity and flatness. Especially for the pulling and curling device of artificial fur machines, since the yarn strips required for artificial fur are thicker and more fluffy, after weaving, the pulling tension of the curling roller will directly affect the surface quality, hairiness and fluffy effect of the artificial fur; therefore, it is particularly important to improve the pulling and curling device of artificial fur machine equipment.

[0005] In order to improve the above problems, a Chinese patent with publication number CN102344049A discloses a curling device for a fur machine, which includes a curling roller and a pair of guide rollers arranged on a frame. The guide roller is arranged on the upper end of the winding roller at the lower end of the knitting cylinder, and the winding roller is located below the center of the two guide rollers. This patent sets a pair of guide rollers at the lower end of the knitting cylinder to guide and pre-press the knitted fabric, and then wind it up through the winding roller. The wound fabric is flat and uniform. However, this method can only enhance the pulling and clamping effect on the fur cloth, and cannot effectively improve the problem of uneven pulling tension on the cloth surface. In actual production, the speed and tightness of the clamping device are often controlled by the experience and estimation of professionals in order to obtain better quality artificial fur cloth, but it is inevitable that the fabric products have serious quality deviations and batch characteristics. Summary of the invention

[0006] In view of the above existing problems, the object of the present invention is to provide a graded clamping and adjusting device on an artificial fur machine, comprising two main parts: a clamping device and a graded adjusting device;

[0007] The clamping device includes a group of clamping parts with a symmetrical structure, wherein the clamping parts are a Q-type column and a pulling stick that cooperate with each other, the pulling stick is located below the Q-type column, and the other side of the symmetrical structure is a P-type column and a corresponding pulling stick; the clamping parts are clamped by the cooperation of the Q-type column (P-type column) and the corresponding pulling stick; wherein the column structure of the clamping parts includes a detachable cylindrical part, a latch and a detachable column at the upper and lower ends; the graded adjustment device includes a graded adjustment rod, a counterweight block and a counterweight placement slot; in one embodiment, the upper and lower ends of the Q-type column and the P-type column in the clamping parts are detachable rounded columns, which can improve the contact force condition of the fur at this location;

[0008] In one embodiment, the surfaces of the q-type column and the p-type column in the clamping device are respectively composed of three arc curves (R1, R2, R3), and the radius of the pulling roller is R4. The three arc curves are respectively R1 is a semi-circular arc curve, R2 is a 1 / 4 arc curve, and R3 is a 1 / 4 arc curve. The surface size of the clamping device and the diameter of the pulling roller are in a fixed relationship of 2R4>R1>R2>R4>R3;

[0009] In one embodiment, the length of the column of the clamping device can be increased or decreased according to the cylinder diameter of the artificial fur machine and the shrinkage rate of the fur to achieve the control of the appropriate size of the clamping device;

[0010] In one embodiment, the surface of the clamping device is made of smooth metal material to reduce the damage to the fur caused by clamping and pulling;

[0011] In one embodiment, two clamping parts with mutually 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 where the center of the pulling rod is located;

[0012] In one embodiment, a step adjustment rod connected to the clamping device is arranged in a direction perpendicular to the axis of the clamping device, and the step adjustment rod can adjust the distance from the curved surface of the arc region of the clamping device R2 to the pulling rod by rotating left and right;

[0013] In one embodiment, the graded adjustment device is adjusted by the weight of the counterweight block so that the vertical clamping force F1 of the clamping device R1 area on the fur is equal to the horizontal clamping force F2 of the clamping device R2 area on the fur after adjustment of the adjustment rod;

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

[0015] In one embodiment, the position of the grading adjustment rod is adjusted according to actual usage. If the fur is very thick, the grading adjustment rod is located obliquely above the horizontal plane of the center of the pulling rod. At this time, the counterweight block is adjusted first to increase the weight, the fur is pressed down, and the adjustment rod drops to the horizontal plane of the center of the circle. At this time, the grading adjustment rod is adjusted again, and the grading adjustment rod is extended and retracted to make the distance D equal to the fabric thickness after the counterweight block is adjusted.

[0016] In one embodiment, the relationship between the adjustment level of the adjustment rod and the placement weight of the counterweight block is: level one corresponds to weight four, and the corresponding fur thickness is x 1 ; Level 2 corresponds to weight 3, and the corresponding fur thickness is x 2 ; Level 3 corresponds to weight 2, and the corresponding fur thickness is x 3 ; Level 4 corresponds to weight 1, and the corresponding fur thickness is x 4 ; where x 1 、x 2 、x 3 , and x 4 They represent different fur thicknesses, and the order of thickness from large to small is x 4 >x 3 >x 2 >x 1 The configuration adjustment relationship of the graded adjustment device can meet the clamping adjustment of furs with different thicknesses in 4 levels.

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

[0018] The patent of the present invention provides a graded clamping and adjusting device on an artificial fur machine, which can accurately control the clamping and pulling force of the artificial fur machine to cope with fur cloth of different thickness and quality requirements by adjusting the graded adjusting device and selecting the counterweight relationship, and coordinating the shape surface of the clamping device with reasonable advantages. Different levels are adjusted by the graded adjusting rod to provide a uniform, graded and strong clamping effect for the clamping device, thereby 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, the device makes very little change to the original curling device of the artificial fur machine. It is only necessary to clamp and install a graded clamping and adjusting device on the artificial fur machine on the original curling roller of the artificial fur machine, and the installation, disassembly, adjustment and other modifications of the device are convenient and labor-saving.

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

[0028] Embodiment 1

[0029] The present embodiment provides a graded clamping and adjusting device on an artificial fur machine, comprising two main parts: a clamping device and a graded adjusting device. The clamping device can provide sufficient and uniform cloth clamping force to ensure the production preparation of fur and the flatness of the cloth. The graded adjusting device can effectively solve the clamping situation of fur of different thicknesses under the machine through graded settings, and can achieve a good clamping effect for artificial fur of different thicknesses and quality requirements. A graded clamping and adjusting device on an artificial fur machine can provide a uniform, graded, and strong clamping effect, significantly improving the production efficiency and product quality of the artificial fur machine.

[0030] The clamping device comprises a set of symmetrical clamping parts, such as Figure 1 As shown, Figure 1 (a) is a schematic diagram of the structure of the graded clamping adjustment device and the pulling rod. Figure 1 (b) is a plan view of the structure of the graded clamping adjustment device and the pulling rod. Figure 1 (c) is a cross-sectional schematic diagram of the graded clamping and adjusting device; Figure 1 As shown in (a) of FIG. 1 , the graded clamping adjustment device with a symmetrical structure is located on the upper part of the pulling rod, and the clamping is achieved by cooperating with the pulling rod; Figure 1 As shown in (b), the length of the clamping cylinder is L1, the length of the pulling rod is L2, and r represents the radius of the rounded corner portion of the loadable rounded corner cylinder; Figure 1 As shown in (c) of the figure, the symmetrical q-type clamping component 1 and the p-type clamping component 2 in the graded clamping and adjusting device are fixedly connected via an internal graded adjusting rod 3.

[0031] The detailed structure of the clamping parts 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 removable rounded corner cylinder at the edge of the clamping part after disassembly. Figure 2 (c) is a schematic diagram of the disassembly process of the detachable column at the edge of the clamping component; Figure 2 As shown in (a) in the figure, the edge of the clamping part is a detachable rounded cylindrical structure, which can improve the contact force condition of the fur at this location; Figure 2 As shown in (b) of FIG. 1 , the removable rounded cylinder is fixed to the clamping component by a latch; Figure 2 As shown in (c) in the figure, the length of the graded clamping device can be adjusted according to the actual usage. The removable rounded cylinder 13 is fixed on the graded clamping adjustment device by the pin 12. When the length of the graded clamping adjustment device needs to be changed, the removable rounded cylinder 13 can be removed, and the removable cylindrical component 11 can be installed on the pin 12. Then, the removable rounded cylinder 13 can be fixed to the clamping component again to realize the change of the length of the clamping component. This measure can not only play a certain role in expanding the fur, but also provide a more uniform and appropriate clamping effect for products with different fur machine barrel diameters and artificial furs 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 excess part of the clamping column compared to the pulling rod will not produce a clamping effect.

[0032] The clamping device is the core part of the device and needs to work on furs of different thicknesses. The surface size of the clamping device is fixedly related to the diameter of the pulling rod. The surface size of the clamping device is composed of three arc curves (R1, R2, R3), and the radius of the pulling rod is R4. Figure 3 As shown; among them, Figure 3 (a) is a schematic cross-sectional view of the clamping component. Figure 3 (b) is a partial enlarged schematic diagram of three arc curves and the pulling rod in the clamping part; Figure 3 As shown in (b), the three arc curves are R1 is a semi-arc curve, R2 is a 1 / 4 arc curve, and R3 is a 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, so as to ensure a better clamping effect. In addition, the surface of the clamping part is made of smooth metal material to reduce the clamping and pulling damage to the fur.

[0033] The graded adjustment device includes a graded adjustment rod, a counterweight block and a counterweight placement slot; Figure 4 As shown, the graded adjustment device includes a graded adjustment rod 3, a counterweight 4, and a counterweight placement groove 5. There is a graded adjustment rod 3 connected to the symmetrical clamping device in a direction perpendicular to the axial direction of the clamping device. The graded adjustment rod 3 can adjust its own length by rotating left and right, thereby adjusting the distance from the curved surface of the clamping device R2 area to the pulling rod; the counterweight 4 is set in the counterweight placement groove 5 between the graded adjustment rods 3, and the clamping action is achieved through the adjustment of the graded adjustment rod 3 in coordination with the arc curved surface of the clamping device and the pulling rod; wherein the counterweight can be loaded and unloaded by cooperating with the adjustment of the graded adjustment rod 3.

[0034] The working principle of the graded adjustment device is as follows Figure 5 As shown, Figure 5 (a) is a detailed cross-sectional schematic diagram of the device. Figure 5 (b) is a schematic diagram of the corresponding level and the distance between the clamping column and the pulling rod during the level adjustment process; Figure 5 As shown in (a), the graded adjustment rods 3 are respectively located on the horizontal plane of the center of the R1 arc area and the horizontal plane of the pulling rod center; the length of the counterweight 4 is L3, and it is located on the horizontal plane of the center of the R1 arc area; the distance between the clamping column and the pulling rod is D, the vertical clamping force of the R1 arc area on the fur is F1, and the horizontal force of the R2 arc area on the fur is F2; ​​through the adjustment of the graded adjustment rods 3, the vertical force F1 and the horizontal force F2 are equal; and the number of graded adjustment rods 3 and the size of the counterweight 4 can also be adjusted according to actual usage to ensure that the vertical force F1 and the horizontal force F2 are equal; L3 of the counterweight 4 and the depth of the counterweight placement groove 5 are both equal to the pulling rod diameter (2R4), and the center of the counterweight 4 is located above the center of the pulling rod. As shown in FIG. Figure 5 As shown in (b), when the adjustment level is four, the distance between the clamping part and the pulling rod is D. The adjustment level is adjusted to one through the graded adjustment rod 3, and the length of the graded adjustment rod 3 is increased, so that the distance D between the clamping part and the pulling rod is reduced, thereby achieving the adjustment of the fur clamping force.

[0035] Place Figure 6 As shown, the relationship between the adjustment level of the graded adjustment rod (3) and the placement weight of the counterweight block (4) is: level one corresponds to weight four, and the corresponding fur thickness is x 1 ; Level 2 corresponds to weight 3, and the corresponding fur thickness is x 2 ; Level 3 corresponds to weight 2, and the corresponding fur thickness is x 3 ; Level 4 corresponds to weight 1, and the corresponding fur thickness is x 4 ; where x 1 、x 2 、x 3 , and x 4 They represent different fur thicknesses, and the order of thickness from large to small is x 4 >x 3 >x 2 >x 1 The configuration adjustment relationship of the graded adjustment device can meet the clamping adjustment of furs with different thicknesses in 4 levels.

[0036] Based on this, the graded clamping adjustment device on the artificial fur machine provided by the present invention can accurately control the clamping and pulling force of the artificial fur machine by adjusting the graded adjustment device and selecting the counterweight relationship, as well as coordinating the shape surface of the clamping device with reasonable advantages, thereby providing a uniform, graded and strong clamping effect, reducing waste caused by uneven fabric thickness or uneven surface, and significantly improving the production efficiency and product quality of the artificial fur machine.

[0037] In this embodiment, a fur cloth with a thickness of about 10mm is used to verify the clamping effect of the device proposed by the present invention. The fur cloth will become fluffy after being placed on the machine, so the fur cloth is much larger than 10mm when on the machine, and 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 adjustment rod 3 of the graded adjustment device can be adjusted and set so that the distance (D) from the curved surface of the clamping device R2 area to the pulling rod is 5-7mm, and the counterweight block 4 of the graded adjustment device is configured at about 500g to ensure that the center of the counterweight block 4 is located above the center of the pulling rod, and to ensure that the lower two of the four adjustment rods 3 are at the level of the center of the pulling rod. This embodiment uses a graded clamping and adjusting device on an artificial fur machine provided by the patent of the present invention to clamp and pull fur, thereby improving the uniformity of fabric thickness and surface flatness, and improving 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 principle of the present invention should be included in the protection scope of the present invention.
