Description

Technical Field

[0001] The utility model belongs to the technical field of non-woven fabric machinery, and particularly relates to a cotton output width adjustment device of an air pressure cotton box and a non-woven fabric production line. Background Art

[0002] The pneumatic hopper is a crucial component in nonwovens production lines, controlling uniform lateral feeding. It serves as the connection between the opener and the carding machine. The carding blower feeds the initially loosened fibers into the upper chamber of the pneumatic hopper. Beater rollers further loosen the fibers, and the web-forming blower delivers the fibers evenly to the lower chamber. Finally, the discharge rollers deliver the fibers evenly to the carding machine or other web-forming equipment. The fiber width delivered by the pneumatic hopper needs to be adjusted based on the subsequent carding machine or other web-forming equipment.

[0003] The conventional method for controlling the fiber width output by a pneumatic hopper involves using multiple baffles of varying thicknesses. A baffle of appropriate thickness is selected and installed on the pneumatic hopper based on the equipment's fiber width requirements. When the fiber width output by the pneumatic hopper needs to be changed while the nonwoven production line is in operation, the production line must first be shut down and then a baffle of appropriate thickness must be replaced. This traditional method of adjusting the fiber width reduces the production line's efficiency, increases worker labor intensity, and significantly impacts economic returns.

[0004] Therefore, how to overcome the above technical deficiencies is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0040] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0041] The core of the utility model is to provide a cotton output width adjustment device for an air pressure cotton box and a non-woven fabric production line, which can adjust the fiber width output by the air pressure cotton box online without stopping the non-woven fabric production line.

[0042] In order to enable those skilled in the art to better understand the technical solution provided by the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] Specifically, please refer to Figures 1-4 The utility model provides a cotton discharge width adjustment device B for a pneumatic cotton box, which is located at the fiber feeding inlet of a group of cotton discharge rollers C of the pneumatic cotton box, and mainly includes a baffle assembly, a sealing assembly and an adjustment assembly.

[0044] The baffle assembly is arranged on the pneumatic cotton box and is located at the end of the cotton discharge roller C. A fiber feeding port for conveying fibers can be formed between the baffle assemblies and between a pair of cotton discharge rollers C. By adjusting the distance between the baffle assemblies, the width of the output fiber can be adjusted.

[0045] The sealing assembly prevents lint from entering between the baffle assembly and wall panel 220 during operation, potentially affecting the adjustment of the adjustment assembly. The sealing assembly includes wall panel 220 and a curtain 210. Wall panel 220 forms part of the air pressure hopper housing A, meaning it is part of the housing A or can be removably attached to the housing A. The upper end of the curtain 210 is mounted on the baffle assembly and connected to the wall panel 220. The lower end of the curtain 210 is connected to the baffle assembly, creating a gap between the baffle assembly and the wall panel 220 for adjusting the cotton output width.

[0046] The adjustment assembly drives the baffle assembly and sealing assembly to move synchronously, thereby adjusting the width. The adjustment assembly includes a compression spring 310, an adjustment screw 320, and a first locknut 330. One end of the adjustment screw 320 is connected to the baffle assembly, and the other end passes through the wall panel 220 and is threadedly connected to the first locknut 330. The compression spring 310 is mounted on the adjustment screw 320, with its ends respectively contacting the baffle assembly and wall panel 220.

[0047] The cotton outlet width adjustment interval can be adjusted by adjusting the position of the first anti-loosening nut 330 on the adjusting screw 320 .

[0048] The cotton output width adjustment device B of the pneumatic cotton box provided by the present invention adjusts the position of the first anti-loosening nut 330 on the adjusting screw 320 by rotating the first anti-loosening nut 330, thereby converting the rotational motion of the first anti-loosening nut 330 into the linear motion of the adjusting screw 320, so that the adjusting screw 320 can drive the baffle assembly and the sealing assembly to perform linear motion. The change in the position of the baffle assembly can then adjust the cotton output width of the pneumatic cotton box. During this period, the compression spring 310 always provides elastic restoring force. The sealing assembly can prevent cotton wool from entering the adjustment assembly and affecting the adjustment effect. When the cotton output width of the pneumatic cotton box needs to be changed, the fiber width output by the pneumatic cotton box can be adjusted online without stopping the non-woven fabric production line. In addition, the cotton output width adjustment steps using the above structure are simple, which can effectively reduce the labor intensity of workers and improve the work efficiency of the non-woven fabric production line.

[0049] To adjust the difference between the maximum and minimum widths of the cotton output from the pneumatic cotton bin, simply change the lengths of the compression spring 310, the adjustment screw 320, and the curtain 210 to accommodate the needs of different nonwoven fabric production lines. The cotton output width adjustment device B provided in this application can adjust the width of the output cotton layer in real time according to the required width of the fiber product, thus providing a highly adaptable design.

[0050] In a specific embodiment, the sealing assembly further includes a pressing plate 230 and a fixing plate 250 , and the baffle assembly includes a baffle 110 and an adjustment plate 120 .

[0051] The pressure plate 230, the curtain 210, the baffle 110, and the adjustment plate 120 are connected by fasteners, and the wall panel 220, the upper end of the curtain 210, and the fixed plate 250 are connected by fasteners. One side of the baffle 110 is in contact with the curtain 210, and the other side is in contact with the adjustment plate 120. One end of the adjusting screw 320 and the adjustment plate 120 can be fixed by welding. The pressure plate 230 is disposed on the side of the curtain 210 away from the baffle 110. Specifically, the pressure plate 230 can be a strip-shaped plate with the same curvature as the baffle 110.

[0052] The fasteners include bolts and locknuts. Specifically, the baffle 110 is connected and fixed to the adjustment plate 120 via a first bolt 111 and a second locknut 112. The curtain 210 is attached to the baffle 110 via a pressure plate 230. The pressure plate 230 is then connected and fixed to the baffle 110 via a second bolt 231 and a third locknut 232.

[0053] Furthermore, a spacer sleeve 241 can be positioned between the curtain 210 and the wall panel 220. The wall panel 220 comprises a main body and a support plate 221. The main body is provided with a mounting opening for the support plate 221, which is located on the side of the wall panel 220 away from the baffle assembly. The main body has a clearance opening below the support plate 221 for mounting the cotton delivery roller C. The upper ends of the curtain 210 are connected to the spacer sleeve 241 and the fixing plate 250, respectively, and fasteners secure the curtain 210 to the support plate 221.

[0054] Specifically, the curtain 210 is secured to the support plate 221 / wall panel 220 via a third bolt 242 and a fourth locknut 243. The height of the spacer 241 matches the thickness of the wall panel 220. The other end of the adjustment screw 320 passes through the support plate 221 and is secured to the support plate 221 via a flat washer 340 and a first locknut 330.

[0055] To facilitate observation of the baffle assembly's adjustment from outside the pneumatic cotton box, a first rectangular hole 222 is formed in the support plate 221, covered with an observation window 400. Observation window 400 is secured to the support plate 221 via a fourth bolt 410. During operation, the pneumatic cotton box allows observation of the cotton noil inside through observation window 400, facilitating adjustments to the box's operating parameters.

[0056] In particular, the pressing plate 230 is made of stainless steel, which can achieve a lightweight design. The baffle 110 and the observation window 400 are organic glass plates, and the curtain 210 is a transparent polyethylene soft curtain, which is conducive to observing the internal situation.

[0057] The number of the pressing plate 230 may be one. Of course, in order to improve the compaction of the curtain 210 , a plurality of pressing plates 230 may be arranged at intervals.

[0058] A second rectangular hole 121 is provided on the adjustment plate 120, which allows one to observe the condition of the baffle assembly through the second rectangular hole 121, or to observe the operation inside the air pressure cotton box through the second rectangular hole 121 and the baffle assembly made of transparent material.

[0059] In a specific embodiment, the lower end and sides of the barrier curtain 210 are longer than the baffle assembly, allowing it to wrap around the baffle assembly and further improve sealing performance. Preferably, the lower end and sides of the barrier curtain 210 extend 3mm-5mm beyond the baffle 110. The bottom of the baffle assembly is spaced apart from the discharge roller C, with the distance between them preferably being 4mm-6mm. The lower end of the barrier curtain 210 is spaced apart from the discharge roller C, with the distance between them preferably being 1mm-2mm.

[0060] When it is necessary to reduce the output fiber width of the pneumatic cotton box, rotate the first anti-loosening nut 330Ⅰ counterclockwise. Through the rotational cooperation of the first anti-loosening nut 330 and the adjusting screw 320, the rotational motion of the first anti-loosening nut 330 is converted into the linear motion of the adjusting screw 320, so that the adjusting screw 320 moves away from the wall panel 220. Then, through the extension function of the compression spring 310 itself, the adjusting plate 120, the baffle 110, the curtain 210 and the pressure plate 230 are driven to move away from the wall panel 220, thereby adjusting the position of the baffle 110 and reducing the output fiber width of the pneumatic cotton box.

[0061] Similarly, when it is necessary to increase the output fiber width of the pneumatic cotton box, rotate the first anti-loosening nut 330 clockwise. Through the rotational coordination of the first anti-loosening nut 330 and the adjusting screw 320, the rotational motion of the first anti-loosening nut 330 is converted into the linear motion of the adjusting screw 320, so that the adjusting screw 320 moves toward the direction close to the wall panel 220, and then drives the adjusting plate 120, the baffle 110, the curtain 210 and the pressure plate 230 to move toward the direction close to the wall panel 220, thereby adjusting the position of the baffle 110, and then increasing the output fiber width of the pneumatic cotton box.

[0062] In addition, the utility model also provides a non-woven fabric production line, including a pneumatic cotton box shell A, a group of cotton discharge rollers C, and a cotton discharge width adjustment device B of the pneumatic cotton box as in the above specific embodiment.

[0063] Obviously, the non-woven fabric production line including the cotton output width adjustment device B of the above-mentioned pneumatic cotton box has the same beneficial effects, which will not be further described here.

[0064] When the pneumatic cotton box has only one discharge width adjustment device B, it can be installed on either side of the pneumatic cotton box housing A. A conventional baffle assembly can be used on the other side of the pneumatic cotton box housing A. That is, in this embodiment, the pneumatic cotton box's discharge mechanism is asymmetrically arranged on the left and right sides. Therefore, the accompanying drawings only illustrate one side; a conventional baffle assembly can be used on the other side depending on the actual situation.

[0065] When the pneumatic cotton box has two discharge width adjustment devices B, the two discharge width adjustment devices B are respectively provided on both sides of the pneumatic cotton box housing A. Since the discharge mechanism of the pneumatic cotton box is symmetrically arranged on the left and right sides, the drawings in this specification only show one side, and there is no need to provide a duplicate discharge width adjustment device B on the other side.
