DETAILED DESCRIPTION

[0029] 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.

[0030] See also Figure 1-Figure 4 The utility model provides a technical solution: a cotton strip feeding structure of a drawing frame, comprising a platform 1 and at least two rollers arranged on the platform 1, and a driving assembly for driving the rollers to rotate. In this embodiment, the driving assembly comprises: a motor 2 arranged in the platform 1; a gear 3 arranged on the lower end shaft of the roller; in this embodiment, the roller comprises a concave roller 4 and a convex roller 5; a cotton guide frame 18 and a pressure roller 19 are arranged at the upper end of the platform 1;

[0031] The above technical solution can be used to automatically feed cotton slivers. Before the cotton slivers enter the drafting part and the sliver forming part, the cotton slivers are first passed through the guide rollers and the pressure rollers 19 of the cotton guide frame 18 in sequence, and then multiple cotton slivers are passed through the gap between the concave roller 4 and the convex roller 5. The motor 2 is started to drive the two mutually meshing gears 3 to rotate, and the gears 3 drive the concave roller 4 and the convex roller 5 to rotate synchronously, and the concave roller 4 and the convex roller 5 turn in opposite directions. During this period, the concave roller 4 and the convex roller 5 squeeze the multiple cotton slivers and transport them to the drafting part.

[0032] like Figure 2 and Figure 3 As shown, the sliver feeding structure also includes a cleaning assembly for cleaning the roller, and the cleaning assembly also includes: a shell 6 with an opening at one end, and the end of the roller away from the sliver extends into the shell 6 through the opening; a plurality of drive rollers 9 rotatably arranged in the shell 6, preferably three drive rollers 9 are arranged in each shell 6, and the three drive rollers 9 are arranged in an arc shape; a cleaning belt 10 is sleeved on the outside of the drive roller 9, and a cleaning brush is arranged on the surface of the cleaning belt 10, and the cleaning brush is in contact with the roller; a driven assembly, which is used to drive the drive roller 9 to rotate while the roller rotates, so that the cleaning brush on the surface of the cleaning belt 10 cleans the cotton wool on the surface of the roller; in this embodiment, the driven assembly includes: a belt pulley 7, which is respectively arranged on the upper end shaft of the roller and the upper end shaft of the drive roller 9; a belt 8 arranged between the two belt pulleys 7;

[0033] The above technical solution can be used to clean the rollers. During the extrusion process, impurities such as cotton wool in the cotton strips will adhere to the surfaces of the concave roller 4 and the convex roller 5. Since a cleaning component is provided, while the concave roller 4 and the convex roller 5 rotate, the drive rollers 9 in their respective housings 6 are driven to rotate through the belt pulley 7 and the belt 8. The drive roller 9 drives the cleaning belt 10 to rotate. Since the direction of the drive roller 9 is the same as that of the respective rollers, the directions of the cleaning belt 10 and the roller are opposite at the position where the cleaning belt 10 contacts the roller, so that the cleaning brush on the surface of the cleaning belt 10 can make the friction with the roller more intense, so that the cotton wool and other impurities on the roller surface can be better adsorbed on the cleaning brush.

[0034] like Figure 2 and Figure 3 As shown, the sliver feeding structure further includes an electrostatic plate 11 disposed in the housing 6, and the electrostatic plate 11 is used to absorb cotton wool accumulated on the surface of the cleaning brush; in this embodiment, the electrostatic plate 11 is preferably disposed on the side of the cleaning belt 10 away from the roller, so as to facilitate cleaning the cleaning brush with accumulated cotton wool impurities;

[0035] The above technical solution can be used to continuously and effectively clean the roller, preventing the cleaning brush on the surface of the cleaning belt 10 from accumulating a lot of cotton wool impurities and affecting its cleaning effect on the roller. Since an electrostatic plate 11 is provided on the other side of the cleaning belt 10, the static electricity of the electrostatic plate 11 can adsorb the cotton wool adsorbed on the cleaning brush to the electrostatic plate 11, and the cleaning brush continues to clean the roller after cleaning.

[0036] Further, such as Figure 2 and Figure 3 As shown, a positioning block 12 is provided on the side of the electrostatic plate 11 away from the roller, and a positioning pin 14 is provided in the platform 1, and the positioning pin 14 is engaged with a positioning groove 13 provided in the positioning block 12; a top opening 15 is provided at the upper end of the platform 1, and a cover plate 17 is provided at the top opening 15, and a support block 16 for supporting the cover plate 17 is provided on the inner wall of the platform 1;

[0037] The above technical solution can facilitate the disassembly and maintenance of the electrostatic plate 11. When maintenance is required, it is only necessary to open the cover 17, carry the electrostatic plate 11 and pull it up, which can drive the positioning groove 13 of the positioning block 12 to disengage the positioning pin 14, so that the electrostatic plate 11 can be removed and the cotton wool on its surface can be scraped off.

[0038] Working principle: before the cotton slivers enter the drafting part and the sliver forming part, the cotton slivers are first passed through the guide rollers and the pressure rollers 19 of the cotton guide frame 18 in sequence, and then the multiple cotton slivers are passed through the gap between the concave roller 4 and the convex roller 5, and the motor 2 is started to drive the two mutually meshing gears 3 to rotate, and the gears 3 drive the concave roller 4 and the convex roller 5 to rotate synchronously, and the concave roller 4 and the convex roller 5 have opposite directions. During this period, the concave roller 4 and the convex roller 5 squeeze the multiple cotton slivers and transport them to the drafting part. During the squeezing process, impurities such as cotton wool in the cotton slivers will adhere to the surface of the concave roller 4 and the convex roller 5. Due to the provision of a cleaning component, while the concave roller 4 and the convex roller 5 rotate, they will pass The belt pulley 7 and the belt 8 drive the driving rollers 9 in the respective housings 6 to rotate, and the driving rollers 9 drive the cleaning belt 10 to rotate. Since the direction of the driving rollers 9 is the same as that of the respective rollers, the two directions are opposite at the position where the cleaning belt 10 contacts the roller, so that the cleaning brush on the surface of the cleaning belt 10 can make the friction with the roller more intense, so that the cotton wool and other impurities on the surface of the roller can be better adsorbed on the cleaning brush. Since an electrostatic plate 11 is provided on the other side of the cleaning belt 10, the static electricity of the electrostatic plate 11 can adsorb the cotton wool adsorbed on the cleaning brush to the electrostatic plate 11, and the cleaning brush continues to clean the roller after cleaning.

[0039] When maintenance is needed, the cover 17 is opened, and the electrostatic plate 11 is lifted and pulled upward to disengage the positioning groove 13 of the positioning block 12 from the positioning pin 14, so that the electrostatic plate 11 can be removed and the cotton wool on its surface can be scraped off.

[0040] 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.

[0041] 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.
