Description

Technical Field

[0001] This utility model relates to the field of roller technology, and in particular to a roller feeding mechanism. Background Technology

[0002] When the cotton gin is working, the cotton is first laid flat on the conveyor belt and fed quickly using a single roller or double roller. Then the whole machine starts to rotate, fluffing the cotton into wadding. However, oil or impurities easily stick to the rollers, which will contaminate the cotton and affect the feeding effect.

[0003] Chinese patent publication number CN213517598U discloses a foreign object detection device for a cotton ginning machine, comprising two roller support seats. The device is fixedly connected to the top of the cotton ginning machine via the roller support seats. A PLC controller is fixedly connected to the top of the cotton ginning machine. A first bearing seat is fixedly connected to the lower inner wall of each of the two roller support seats. A first bearing is rotatably connected to the middle of each of the two first bearing seats. A second bearing seat is fixedly connected to the upper inner wall of each of the two roller support seats. A second bearing is rotatably connected to the middle of each of the two second bearing seats. A lower roller is rotatably connected between the two first bearings. Lower roller square sleeves are fitted on the outer sides of both ends of the lower roller. A lower roller rack is fixedly connected to the surface of the lower roller. A drive motor is rotatably connected to one end of the lower roller. The above detection device cannot repeatedly clean foreign objects on the roller, thus affecting the cleaning effect.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0024] See Figures 1 to 7 This utility model provides a roller feeding mechanism, which includes: a pair of rollers 1 arranged vertically, the rollers 1 rotating relative to each other can convey compressed or impurity-containing cotton to a cotton ginning machine for processing; the pair of rollers 1 are driven to rotate by a drive member 21 and the rotation directions of the pair of rollers 1 are opposite; support seats 2 are respectively provided on both sides of the pair of rollers 1 to support the rotation of the rollers 1, and bearing seats 26 are provided in the support seats 2 to provide support for the rollers 1 and ensure stable rotation of the rollers 1; a reciprocating bearing plate 4 is slidably connected to the support seats 2, and a cleaning brush 5 is engaged on the bearing plate 4 to clean the rollers 1, which can clean impurities, oil stains and other contaminants adhering to the surface of the rollers 1.

[0025] See Figures 1 to 7Preferably, a driving member 21 is fixedly connected to the support base 2 of this utility model. The driving member 21 drives one roller 1 to rotate. A transmission wheel 3 is fixedly connected to the end of each pair of rollers 1 away from the driving member 21. The two transmission wheels 3 mesh with each other. When the driving member 21 drives one roller 1 to rotate, the two meshing transmission wheels 3 drive the other roller 1 to rotate and the rotation directions of the two rollers 1 are opposite.

[0026] See Figures 1 to 7 In addition, each of the two rollers 1 of this utility model is provided with a bearing seat 26 on both sides. The bearing seat 26 is located inside the support seat 2, and a stud 24 screwed to the support seat 2 is rotatably connected above the bearing seat 26 located at the top. The distance between the two rollers 1 can be adjusted by rotating the stud 24.

[0027] See Figures 1 to 7 Furthermore, the bearing plate 4 of this utility model is provided with a groove 43 for accommodating the stud 24. The groove 43 can ensure that the bearing plate 4 does not interfere with the stud 24 when it reciprocates. The bottom of the bearing plate 4 abuts against the slide rail 25 that restricts the bearing plate 4 from sliding along the roller 1 axis. The slide rail 25 can ensure that the bearing plate 4 moves stably. A baffle 41 is provided on each side of the bearing plate 4.

[0028] See Figures 1 to 7 Better still, in this invention, one of the baffles 41 abuts against a push block 6 rotatably connected to the support base 2, and the push block 6 is elliptical in shape. The other baffle 41 is slidably connected to the support rod 22. The support rod 22 is sleeved with an elastic element 23. When the push block 6 rotates, when the maximum diameter of the push block 6 abuts against the baffle 41, it drives the baffle 41 to move the bearing plate 4. At this time, the elastic element 23 contracts. When the minimum diameter of the push block 6 abuts against the baffle 41, the elastic element 23 naturally extends, driving the bearing plate 4 to move in the opposite direction, thereby realizing the reciprocating movement of the bearing plate 4. The top of the cleaning brush 5 is provided with several fixing clips 51. Several fixing clips 51 are snapped onto the bearing plate 4, and the opening direction of several fixing clips 51 is set at the input end of a pair of rollers 1, ensuring that when the rollers 1 rotate, the fixing clips 51 can be tightly attached to the bearing plate 4.

[0029] Working principle: By rotating the stud 24, the gap between the two rollers 1 can be adjusted. By activating the drive component 21, the two rollers 1 are driven to rotate in opposite directions. The telescopic component 7 is activated, and the telescopic component 7 controls the vertical rod 71 to drive the cylindrical pin to slide in the horizontal groove 62, thereby driving the rotating rod 61 to rotate. The rotating rod 61 drives the push block 6 to rotate. The push block 6 abuts against the baffle 41, driving the support plate 4 to move. The support plate 4 is secured with a cleaning brush 5 by a fixing clip 51, and the opening of the fixing clip 51 faces the input end of the pair of rollers 1 to ensure that the fixing clip 51 will not fall off when the rollers 1 rotate. The cleaning brush 5 can clean the rollers 1.

[0030] In summary, this utility model provides a roller feeding mechanism, comprising: a pair of rollers arranged vertically, the rollers rotating relative to each other to transport compressed or impurity-containing cotton to a cotton ginning machine for processing; the pair of rollers are driven to rotate by a drive component and the rotation directions of the pair of rollers are opposite; support seats are respectively provided on both sides of the pair of rollers to support the rotation of the rollers, and bearing seats are provided in the support seats to provide support for the rollers and ensure stable rotation of the rollers; a reciprocating carrier plate is slidably connected to the support seats, and a cleaning brush for cleaning the rollers is engaged on the carrier plate to clean impurities, oil stains, etc. adhering to the roller surface; the beneficial effects of this utility model are: the pair of relatively rotating rollers can realize the feeding function; the reciprocating carrier plate can ensure that the cleaning brush cleans the rollers repeatedly, improving the cleaning effect, while avoiding impurities on the rollers from contaminating the raw materials; and the cleaning brush engaged on the carrier plate can be easily installed and replaced.
