[0033] In order to make the personnel in the technical field better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application.

[0034] As Figures 1 to 3 Indicated, a warp knitting machine cloth collecting mechanism, including mounting seat 1 and two support frames 2 that are oppositely arranged on mounting seat 1, sleeve shaft 3 is rotationally arranged on support frame 2, and the warp knitting machine cloth collecting mechanism further includes:

[0035] The collection part 4 for winding cloth is detachably installed between the two support frames 2.

[0036] The collection part 4 includes:

[0037] The spline shaft 41 is axially inserted into one side of the sleeve shaft 3.

[0038] The cloth roller 42 is fixed between the two spline shafts 41.

[0039] The cloth pressing strip 44 is hinged to the cloth pressing groove 43 axially arranged on the surface of the cloth roller 42.

[0040] The two cloth blocking plates 46 are relatively fixed to the two ends of the cloth roller 42 for limiting and guiding when the cloth is rolled.

[0041] The limiting member 45 is arranged between the end surface of the cloth pressing strip 44 and the cloth blocking plate 46, and is used to fix the two ends of the cloth pressing strip 44.

[0042] After the replacement operation of the collecting part 4 is completed, the cloth end needs to be fixed on the collecting part 4 first. The cloth end fixing operation process is as follows: first, operate the limiting member 45 to release the limiting and fixing effect of the limiting member 45 on the cloth pressing strip 44, then turn the cloth pressing strip 44 outward from the cloth pressing groove 43, then adhere the end of the cloth to the inner wall of the cloth pressing groove 43 along the length direction of the cloth pressing groove 43, and finally reset the cloth pressing strip 44, turn it over, and operate the limiting member 45 to fix the cloth pressing strip 44, so as to press the end of the cloth between the opposite surfaces of the cloth pressing strip 44 and the cloth pressing groove 43. In this way, the difficulty of the cloth end fixing operation can be reduced, and the fixing effect of the cloth and the efficiency of the cloth end fixing operation can be improved under the premise of keeping the cloth flat.

[0043] In this embodiment, the limiting member 45 includes:

[0044] The plug block 452 is inserted into the limiting hole 451 arranged on the end surface of the cloth pressing strip 44, and one end of the plug block 452 is inserted into the insertion hole 458 arranged on the cloth blocking plate 46.

[0045] The spring 455 is slidingly inserted into the limiting groove 453 arranged in the limiting hole 451.

[0046] The sliding block 454 is slidingly inserted into the limiting groove 453, and is located between the spring 455 and the limiting hole 451. The remaining end of the plug block 452 is fixed on the sliding block 454.

[0047] The movable distance of the plug block 452 is greater than the axial length of the limiting hole 451, and the movable distance of the plug block 452 is less than the axial length of the insertion hole 458 and the limiting hole 451.

[0048] The insertion block 452 is designed to avoid being pushed into the limiting slot 453 completely and difficult to be pulled out again when the insertion block 452 is pushed to retract into the limiting slot 453. In the later stage of the operation of fixing the end of the cloth, the end surface of the insertion block 452 is always in contact with the cloth blocking disc 46 until the cloth pressing strip 44 is reset. At this time, one end of the insertion block 452 is aligned with the insertion hole 458 and inserted into the insertion hole 458, so as to fix the cloth pressing strip 44. The cloth pressing strip 44 can press the end of the cloth tightly between the opposite surfaces of the cloth pressing strip 44 and the cloth pressing groove 43, so as to improve the firmness of the fixed end of the cloth, avoid the loosening of the end of the cloth during the rolling of the cloth, affect the smooth rolling of the cloth, or easily cause the wrinkles on the surface of the cloth and affect the beauty of the collected cloth.

[0049] In the embodiment, the limiting member 45 further comprises:

[0050] The push block 456 is slidably connected with the through slot 457 arranged between the cloth pressing strip 44 and the limiting slot 453. One side of the push block 456 is fixed on the sliding block 454. By pushing the push block 456 horizontally away from one end of the through slot 457, the sliding block 454 and the insertion block 452 can be pushed to move synchronously, and the spring 455 is compressed. Until one end of the insertion block 452 is separated from the insertion hole 458 on the cloth blocking disc 46, the cloth pressing strip 44 can be flipped to the outside of the cloth pressing groove 43. During the flipping of the cloth pressing strip 44, the end surface of the insertion block 452 always keeps in contact with the surface of the cloth blocking disc 46, so as to release the limiting and fixing of the cloth pressing strip 44. After the end of the cloth is placed in the cloth pressing groove 43, the cloth pressing strip 44 is reset and flipped until one end of the insertion block 452 is aligned with the insertion hole 458. Under the elastic force of the spring 455, one end of the insertion block 452 is inserted into the insertion hole 458, so as to realize the limiting and fixing of the cloth pressing strip 44, and the end of the cloth is tightly fixed. The operation difficulty and efficiency are high.

[0051] In the embodiment, the length of the cloth pressing strip 44 is equal to that of the cloth pressing groove 43, and the length of the cloth pressing groove 43 is greater than the width of the cloth. In this way, the end of the cloth with a width less than the length of the cloth pressing groove 43 can be tightly fixed during the fixing of the end of the cloth, so as to improve the application range.

[0052] In the embodiment, the cloth collecting mechanism of the warp knitting machine further comprises:

[0053] The two sliding seats 6 are slidably connected with the two guide slots 5 arranged on the mounting seat 1 respectively, and the bottom of the supporting frame 2 is fixed on the top of the sliding seat 6.

[0054] The two telescopic cylinders 7 are fixed on the mounting seat 1 respectively, and the free ends of the telescopic cylinders 7 are fixed on the supporting frame 2. The telescopic cylinders 7 are used to push and pull the supporting frame 2 to move linearly and reciprocally.

[0055] After a roll of cloth is finished, the two support frames 2 can be moved away from each other by controlling the telescopic cylinder 7 to retract and dragging the support frame 2 to move, so that the spacing between the two support frames 2 is enlarged, the roll of cloth is quickly unloaded, and the new collecting part 4 is installed, which greatly simplifies the replacement step of the collecting part 4 and improves the efficiency of the replacement operation.

[0056] In the embodiment, the warp knitting machine cloth collecting mechanism further comprises a driving part arranged on one of the support frames 2, and the driving part is used to drive the sleeve shaft 3 to rotate.

[0057] The above only describes the preferred embodiments of the present application, and the parts not described in the present application can be realized by using or referring to the existing technology. Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or replacements made by the person skilled in the art within the essential scope of the present application should also belong to the protection scope of the present application.
