Description

Technical Field

[0001] The utility model relates to the technical field of cotton carding machines, in particular to a strip forming structure for cotton carding machines. Background Art

[0002] The working principle of the carding machine is to open, comb and remove impurities from the cotton (fiber) rolls sent from the previous process or the oily cotton (chemical fiber) layer supplied by the cotton box, so that all the curled cotton loops become basically straight single fibers. In the process, the broken seeds, impurities and short fibers left over from the cotton cleaning process are removed, and then the cotton strips of a certain specification are integrated and stored in the cotton cylinder for use in the drawing process. However, when the strip-forming structure of the carding machine is in operation, the surfaces of the pressure rollers and guide rollers are prone to adhere to substances such as short fibers and impurities. After long-term use, it is easy to reduce the quality of the cotton strips, and impurities such as short fibers will affect the quality of the cotton strips. Patent numbers are CN204874915U and CN216039992U, both of which provide a cotton wool cleaning device in the strip-forming structure of the carding machine. However, although the cotton wool is light in weight, it is easy to clog the air outlet of the cotton wool collecting device after being collected, causing the wind force to weaken or be unable to continue collecting the cotton wool. At this time, timely cleaning is required, but when cleaning the cleaning device, the machine needs to be stopped for cleaning, which is time-consuming and labor-intensive. Utility Model Content

[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a strip-forming structure for a carding machine.

DETAILED DESCRIPTION

[0018] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0019] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] A strip forming structure for a carding machine, such as Figure 1 and Figure 2 As shown, the strip forming machine housing 1 is provided with a feed port 2, a strip forming roller 3 and a discharge port 4 from left to right in sequence, which are located in a horizontal straight line, and the strip forming roller 3 includes an upper pressing roller 31 and a lower pressing roller 32, which are used for extruding and forming cotton wool strips;

[0021] A cleaning cam 5 is provided at the upper right end of the upper pressure roller 31 and the lower right end of the lower pressure roller 32, respectively. A plurality of cleaning brushes 51 are provided on the convex arc surface of the cleaning cam 5, which abut against the upper pressure roller 31 and the lower pressure roller 32;

[0022] like Figure 3 and Figure 4 As shown, the cleaning cam 5 is hollow inside, and a cleaning brush 51 and a suction port 52 (a plurality of holes with a diameter of less than 1 cm can be provided) are provided on the convex arc surface of the cleaning cam 5, and the cleaning cam 5 is hollow inside, and the rear end face of the cleaning cam 5 is fixedly connected to a horizontal pipe 7, and the front end face is fixedly connected to a horizontal rod 8, and the cleaning cam 5 is connected to an exhaust device 6 fixed to the rear end face of the strip-forming housing 1 through the horizontal pipe 7, and a rotating fixing device 9 is fixedly provided on the front end face of the horizontal rod 8;

[0023] like Figure 5 As shown, the rectangular torsion bar 91 on the rotating fixing device 9 is fixed on the end face of the horizontal rod 8, and the fixing plate 92 extends out of the end face of the horizontal rod 8. The fixing plate 92 is provided with mounting holes and is fixedly connected to the strip casing 1 by bolts.

[0024] When the strip forming roller 3 is working, the upper pressing roller 31 and the lower pressing roller 32 on the strip forming roller 3 rotate in opposite directions, pressing the cotton wool continuously entering from the feed port 2 into a strip shape, and then outputting it from the discharge port 4;

[0025] When the upper pressure roller 31 and the lower pressure roller 32 rotate, the cleaning brush 51 on the cleaning cam 5 can intercept the cotton wool remaining on the upper pressure roller 31 and the lower pressure roller 32 on the cleaning brush 51, and then the exhaust device 6 is started, and the exhaust device 6 can suck a part of the cotton wool from the cleaning brush 51 through the suction port 52 into the inner cavity of the cleaning cam 5 until it reaches the cotton wool filter in the horizontal pipe 7 and is intercepted.

[0026] When the cotton wool in the horizontal pipe 7 blocks the cotton wool filter and needs to be cleaned, first stop the operation of the exhaust device 6, then separate the exhaust device 6 from the connecting port connected to the horizontal pipe 7 through the hose, then remove the screws on the fixing plate 9 by a wrench, so that the fixing plate 9 is separated from the strip forming machine casing 1, and then hold the torsion bar 91 on the rotating fixing device 9 with one hand to rotate the cleaning cam 5 so that the raised arc surface of the cleaning cam 5 is away from the roller surface of the strip forming roller 3, and then pull the cleaning cam 5 forward to make the horizontal pipe 7 separate from the strip forming machine casing 1, and then open the opening and closing door set on the side end face of the strip forming machine casing 1 (mainly used for maintenance, not shown in the figure, generally set on the side end face of the strip forming machine casing 1), manually replace the cotton wool filter in the horizontal pipe 7 through the opening and closing door, and manually remove the cotton wool trapped on the cleaning brush 51. After cleaning, restore the cleaning cam 5 according to the above reverse steps and fix it so that the cleaning brush 51 on the cleaning cam 5 abuts against the roller surface of the strip forming roller 3.

[0027] For the sake of safety in use, a blocking plate A through which the cleaning cam 5 can pass is provided in the strip forming machine casing 1 in front of the strip forming roller 3, to facilitate the cleaning cam 5 to detach from the strip forming roller 3 and to facilitate the cleaning of cotton wool; a blocking plate B through which the horizontal pipe 7 can pass is provided in the strip forming machine casing 1 behind the strip forming roller 3, and the blocking plates A and B divide the strip forming machine casing 1 into three spaces, front and rear, to facilitate the disassembly and maintenance of the horizontal pipe 7.

[0028] The horizontal pipe 7 and the strip forming machine casing 1 are fixed by a rubber plug, that is, the horizontal pipe 7 is provided with a through hole on the end face of the strip forming machine casing 1, and the rubber plug is fixedly sleeved on the horizontal pipe 7. The horizontal pipe 7 is fixed in the through hole by the pressure of the rubber plug inserted into the through hole of the horizontal pipe 7.

[0029] The above description is only an explanation of the preferred embodiments of the present application and the technical principles and other schemes used. At the same time, the scope of the invention involved in the present application is not limited to the technical scheme formed by a specific combination of the above technical features, but also should cover other technical schemes formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) by each other to form a technical scheme.
