Description

Technical Field

[0001] The utility model relates to the technical field of fabric grasping, in particular to a fabric grasping jaw. Background Technique

[0002] Fabric is a commonly used material in decorative materials. It includes various fabrics such as chemical fiber carpets, non-woven wall coverings, linen, nylon, colored adhesive tapes, flannel, etc. A large amount of fabric is used for wall surface decoration, partition, and background treatment, which can also form a good commercial space display style. In textile machinery, after the fabric is manufactured, it needs to be wound around a reel for storage due to its large size. During handling, due to the long length of the fabric, it is difficult for manual labor to carry it, so it is necessary to use a fabric grasping jaw to complete the handling of the fabric.

[0003] The patent document with the publication number of CN213499246U discloses a fabric grasping jaw, which includes a mounting plate. A rotary cylinder is arranged at the bottom of the mounting plate, and the output end of the bottom of the rotary cylinder is connected with a fixed seat. A hydraulic cylinder is arranged at the center of the bottom of the fixed seat, a hydraulic rod is arranged inside the hydraulic cylinder, the bottom end of the hydraulic rod is fixedly connected with a linkage block, two first link rods are hinged on both sides of the linkage block, a second link rod is hinged between the other ends of the two link rods on the same side, the bottom end of the second link rod is connected with a clamping arm, and the joints between the two second link rods and the clamping arm are respectively hinged inside the hinge grooves arranged on both sides of the hinge platform arranged therebetween. The fabric grasping jaw provided by the utility model eliminates the work of manually transferring the fabric stack, and at the same time, the design of the clamping pins can play a limiting function during the process of clamping the fabric, so that it is not necessary to align whether the clamping jaws on both sides are symmetrically located on both sides of the center of gravity of the fabric stack before clamping, which greatly improves the work efficiency.

[0004] The above patent can only grasp the rolled fabric. When the axial length of the rolled fabric is too long, simply using the jaw to grasp one side of it, the fabric is likely to tilt towards one end, and then the fabric at the headquarters will slip, and the clamping is unstable.

[0028] Embodiment

[0029] Referring to Figures 1-3 , for an embodiment of the present utility model, a fabric grasping claw is provided, including: a grasping unit 100, a rotary driving unit 200, a grasping rod tightening unit 300, and an axial adjusting unit 400.

[0030] Among them, the grasping unit 100 includes a mounting plate 101 and a fixed cylinder 102 located directly below the mounting plate 101. Claw plates 103 are symmetrically arranged on both sides of the fixed cylinder 102. A grasping rod 104 is fixedly installed on one side of each claw plate 103 close to the center of the fixed cylinder 102. The grasping rod 104 is a hollow structure. The lower end of the fixed cylinder 102 is fixedly connected with symmetrically positioned electric telescopic rods 105. The lower end of each electric telescopic rod 105 is fixedly connected with a tightening sleeve 106. Through the arrangement of the tightening sleeve 106 and the electric telescopic rod 105, the grasping stability of the fabric by the grasping claw can be improved in cooperation with the grasping rod 104 and the claw plate 103. The tightening sleeve 106 is arranged in an arc shape, and a grid rubber pad is padded on the inner wall of the tightening sleeve 106. The setting of the grid silicone pad further improves the tightening effect of the tightening sleeve 106 on the fabric;

[0031] The rotation drive unit 200 includes a rotation drive unit 200 for driving the fixed cylinder 102 to rotate;

[0032] Furthermore, the rotation drive unit 200 includes a hollow cylinder 201 fixedly installed at the center of the lower end of the fixed plate and a rotating rod 202 rotatably connected to the lower end of the hollow cylinder 201. The lower end of the rotating rod 202 is fixedly connected to the center of the upper end of the fixed cylinder 102. A fixed ear 203 is fixedly connected to the lower end of the side wall of the hollow cylinder 201. A rotating motor 204 is fixedly installed on the fixed ear 203. The output shaft of the rotating motor 204 penetrates through the fixed ear 203 and is fixedly sleeved with a driving gear 205.

Second bevel gears 403 meshing with the first bevel gear 402 are symmetrically arranged in the fixed cylinder 102. Each second bevel gear 403 is rotatably connected to the inner end wall of the fixed cylinder 102 through a threaded rod 404. A threaded block 405 is threadedly connected to the threaded rod 404. One end of each threaded block 405 away from the second bevel gear 403 is fixedly connected to a pair of symmetrically positioned push rods 406. One end of each pair of push rods 406 away from the threaded block 405 is fixedly connected to the corresponding grab plate 103.

[0036] During use, start the rotary motor 204, drive the rotating rod 202 and the fixed cylinder 201 to rotate through the driving gear 205 and the driven gear 206, so that the fixed cylinder 201 is arranged parallel to the rolled fabric. Then rotate the adjusting rod 401 forward, and adjust the distance between the grasping plate 103 and the grasping rod 104 through the cooperation of the first helical gear 402 and the second helical gear 403, and use it according to the axial length of the rolled fabric. When the grasping rod 104 is inserted into both ends of the rolled fabric reel, restart the inside of the grasping rod 104 through the air pump 303, and the elastic telescopic airbag 302 presses against the inner wall of the rolled fabric reel, which can clamp from both ends of the fabric. Compared with the grasping method of clamping the side surface of the fabric, the grasping is more stable and the fabric will not tilt.
