Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary components and devices for canvas spinning, and in particular to a cotton feeding adjustment device for canvas spinning. Background Technology

[0002] In the spinning process of a spinning machine used to produce canvas yarn, the cotton sliver passes through the feeding channel, then through the holding area composed of the feeding roller and the feeding plate, and is then grasped by the combing roller for combing and impurity removal.

[0003] Existing technologies have the following problems: Extensive searches revealed that patent application CN201420300331.2 discloses a cotton feeding adjustment device for canvas spinning. This patent uses an adjusting screw to drive the extension and retraction of a spring. Due to inertia, the spring returns to its original shape, and the cotton feeding plate follows the spring, swinging around the pin as a fulcrum to change position. This allows adjustment of the distance between the cotton feeding plate and the gripping area of ​​the cotton feeding roller. However, this patent uses manual rotation of the screw to adjust the distance between the cotton feeding plate and the gripping area of ​​the cotton feeding roller, which reduces accuracy and introduces certain errors. Under long-term operation, the distance between the gripping area formed by the cotton feeding plate and the cotton feeding roller is difficult to guarantee, and the cotton sliver cannot be smoothly fed into the gripping range of the carding roller, reducing the carding efficiency of the carding roller.

[0004] To address these shortcomings, we proposed a cotton feeding adjustment device for canvas spinning. Utility Model Content

One end of the cotton feeding plate is fixed to the frame by a pin, and the cotton feeding plate swings around the pin as a fulcrum. A through groove is provided on the frame, and a connecting rod is installed through the inside of the through groove. One end of the connecting rod is hinged to the cotton feeding plate by a hinge. A limit groove is provided on the inner wall of the through groove, and a limit block is slidably connected inside the limit groove. The outer wall of the limit block is welded to the outer wall of the connecting rod. An adjusting threaded rod is installed at one end of the connecting rod. A housing is fixedly installed on one side surface of the frame, and a gear ring is rotatably connected inside the housing. A threaded block is fixedly connected to the inner wall of the gear ring, and the threaded block cooperates with the adjusting threaded rod. A servo motor is fixedly installed on the frame, and a gear is installed at the output end of the servo motor, and the gear meshes with the gear ring.

[0007] Preferably, the surface of the housing is provided with a groove for cooperating with the gear, and the width of the groove is greater than the thickness of the gear.

[0020] In this embodiment: the surface of the housing 9 is provided with a groove for cooperating with the gear 13, and the width of the groove is greater than the thickness of the gear 13.

[0021] Specifically, this allows gear 13 to mesh with gear ring 10 through the groove, thereby driving gear ring 10 to rotate in both directions.

[0022] In this embodiment: one end of the adjusting threaded rod 2 passes through the housing 9.

[0023] Specifically, under the limiting and guiding action of the limiting groove 7 and the limiting block 8, the servo motor 12 drives the gear 13 to rotate in both directions, and the rotation of the gear 13 drives the gear ring 10 to rotate in both directions. Thus, with the cooperation of the threaded block 11, the rotational motion can be converted into linear motion, and the adjusting threaded rod 2 can be driven to move horizontally left and right.

[0024] In this embodiment: the gear ring 10 is rotatably connected to the housing 9, and the diameter of the housing 9 is larger than the diameter of the gear ring 10.

[0025] Specifically, this allows the gear ring 10 to rotate within the housing 9.

[0026] In this embodiment: the diameter of the threaded block 11 is smaller than the diameter of the gear ring 10.

[0027] Specifically, the threaded block 11 can be fixed inside the gear ring 10.

[0028] In this implementation plan: the adjusting threaded rod 2 is used in conjunction with the through groove.

[0029] Specifically, this allows the adjusting threaded rod 2 to be fixedly connected to the connecting rod 5 for use.

[0030] Working Principle: During operation, a servo motor 12 drives the adjusting screw 2 to move horizontally, replacing manual adjustment of the distance between the gripping areas of the feed plate 3 and the feed roller 4 by turning the screw. This significantly improves adjustment accuracy, reduces errors, and ensures that the distance between the gripping areas formed by the feed plate 3 and the feed roller 4 remains constant during long-term operation. This allows for smooth feeding of the sliver to the gripping range of the combing roller, improving the combing efficiency. It should be noted that the servo motor 12 can be a packaged...
