Description

Technical Field

[0001] The utility model relates to the technical field of cotton carding machines, in particular to an automatic tensioning and adjusting device for a cover plate of a cotton carding machine. Background Art

[0002] The carding machine is used to process cotton fiber and chemical fiber. It belongs to textile machinery and is mainly composed of three parts: the top combing part, the main combing part and the strip forming part. The main combing part includes the cylinder, the cover plate, the doffer and the large leak bottom. The cylinder cooperates with the movable cover plate to further and finely comb the fibers, so that the fibers are fully straightened and separated, and some short fibers and fine impurities are removed. The height and tightness of the cover plate of the traditional carding machine cannot be adjusted, and the stress conditions of different cotton fibers are different, so it does not have the function of flexibly adjusting the tightness of the cover plate.

[0003] The Chinese utility model patent with authorization announcement number CN217869258U discloses a high-efficiency carding machine for processing antioxidant cotton fabrics. The solution is to change the bracket supporting the cover plate into a style with adjustable upper and lower heights, and flexibly adjust the tightness according to the different cotton materials being processed. When adjusting the tightness of the cover plate, it is necessary to first loosen the fixing bolts and move the cover plate support strips up and down along the slide groove to adjust the actual height and spacing of the cover plate rollers, thereby adjusting the tightness of the cover plate. When adjusted to the appropriate degree, re-screw the fixing bolts, and the fixing bolts are inserted into the corresponding adjustment slot holes to fix the position of the cover plate support strips.

[0004] This solution has the following problems: when the tightness of the cover needs to be adjusted, the fixing bolts need to be unscrewed or tightened, and the position of the cover roller is adjusted by adjusting the relative positions of the cover support strips and the slide grooves. Moreover, each cover support strip needs to be debugged separately, which is cumbersome to operate and is not conducive to improving work efficiency. Utility Model Content

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0031] See also Figure 1-Figure 5 The utility model provides a technical solution: an automatic tensioning and adjusting device for a cotton carding machine cover, comprising a plurality of cover rollers 5 arranged in a machine body 1, a cover plate 6 is sleeved on the outside of the cover rollers 5, and the cover plate 6 is located above the cylinder 2; the adjusting device also includes two adjusting components relatively arranged at the front and rear sides of the machine body 1, and the adjusting component is used to adjust the support tension of the cover roller 5 on the cover 6, and the adjusting component includes: a fixed shaft 3 fixedly arranged on the machine body 1; a plurality of support rods 4 rotatably connected to the fixed shaft 3 at one end, the number of the support rods 4 is the same as the number of the cover rollers 5, and the end shaft of the cover roller 5 is rotatably connected to the rotating groove opened at the other end of the support rod 4; an adjusting component for automatically adjusting the angle between the support rods 4; in this embodiment, the adjusting component includes: a track 7 arranged on the inner wall of the machine body 1; a slider 10 slidably connected to the track 7; an electric push rod 11 connected to the slider 10; a convex column 13 arranged on the surface of the support rod 4, and the convex column 13 cooperates with the limiting groove 12 opened at the output end of the electric push rod 11;

[0032] The above technical solution can be used to quickly adjust the tension of the cover 6. The electric push rod 11 is started to extend, and the output end of the electric push rod 11 pushes the support rod 4 to rotate around the fixed axis 3, thereby increasing the angle of the support rod 4. The support rod 4 drives the cover roller 5 rotatably connected to it to rotate synchronously, thereby increasing the angle of the cover roller 5, thereby increasing the tension of the cover 6. While the support rod 4 rotates, the vertical height of the boss 13 decreases, thereby driving the electric push rod 11 to descend, and the slider 10 on the side of the electric push rod 11 slides down along the track 7.

[0033] Further, such as Figure 3 As shown, the adjustment device further includes: a fixing block 8 disposed on the side of the track 7; a fixing bolt disposed in a bolt hole 9 opened in the fixing block 8;

[0034] The above technical solution can be used to conveniently install the track 7 on the inner wall of the body 1 through fixing bolts.

[0035] Further, such as Figure 5 As shown, the support rod 4 includes a fixed end 401 rotatably connected to the fixed shaft 3 and a movable end 402 with a rotating groove, the movable end 402 is provided with a slide rod 15, and the slide rod 15 is slidably matched with the slide groove 16 opened in the fixed end 401; the adjustment device also includes: a tightening bolt 18, which is rotatably arranged in a rotating hole 17 opened in the fixed end 401, and one end of the tightening bolt 18 is matched with a positioning groove 19 opened in the slide rod 15.

[0036] The above technical solution can be used to fine-tune the tension of the cover 6. When it is necessary to fine-tune the tension of the cover 6, unscrew the tightening bolt 18 to disengage one end of it from the positioning groove 19 of the slide bar 15, thereby pushing the slide bar 15 to slide in the slide groove 16. When the slide bar 15 moves, it will drive the cover roller 5 to move synchronously. When the slide bar 15 reaches the desired position, rotate the tightening bolt 18 to insert it into the positioning groove 19 to complete the locking of the slide bar 15, thereby achieving fine-tuning of the tension of the cover 6.

[0037] Further, such as Figure 2 As shown, a convex plate 14 is provided at one end of the support rod 4 that is in contact with the cover roller 5, so that the distances between all the support rods 4 and the cover roller 5 are equal;

[0038] The above technical solution can prevent a large gap from existing between the support rod 4 and the cover roller 5 .

[0039] Working principle: When the tension of the cover plate 6 needs to be increased, the electric push rod 11 is started to extend, and the output end of the electric push rod 11 pushes the support rod 4 to rotate around the fixed shaft 3, thereby increasing the angle of the support rod 4, and the support rod 4 drives the cover plate roller 5 connected to it to rotate synchronously, so that the angle of the cover plate roller 5 becomes larger, so that the tension of the cover plate 6 is increased. When the support rod 4 rotates, the vertical height of the protrusion 13 decreases, thereby driving the electric push rod 11 to descend, and the slider 10 on the side of the electric push rod 11 slides down along the track 7;

[0040] When it is necessary to fine-tune the tension of the cover 6, unscrew the tightening bolt 18 so that one end of it disengages from the positioning groove 19 of the slide bar 15, thereby pushing the slide bar 15 to slide in the slide groove 16. The movement of the slide bar 15 will drive the cover roller 5 to move synchronously. When the slide bar 15 reaches the desired position, rotate the tightening bolt 18 to insert it into the positioning groove 19 to complete the locking of the slide bar 15, thereby achieving fine-tuning of the tension of the cover 6.

[0041] Thereby completing a series of tasks, the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0042] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
