Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric production, and particularly relates to a double-channel rough opener. Background Technique

[0002] Non-woven fabric is a fabric formed without spinning and weaving. It only arranges textile staple fibers or filaments in a directional or random manner to form a fiber web structure, and then is reinforced by mechanical, thermal bonding or chemical methods. It is a new fiber product directly formed by using polymer chips, staple fibers or filaments through various fiber web forming methods and consolidation technologies, with a soft, breathable and planar structure. Non-woven fabrics are widely used in various fields. In the aspect of medical and health fabrics, they are often used to make surgical gowns, protective clothing, disinfection wrapping cloths, masks, diapers, sanitary napkins for women, etc.

[0003] When making medical and health fabrics, the initial step is to preliminarily disperse the fiber cotton material by using a cotton-beating roller for the use of equipment in subsequent processes. However, the existing rough opener has a relatively simple structural design. It uses a single cotton-beating roller to open the fiber cotton material, resulting in poor opening effect. Moreover, the fiber cotton material is relatively firm, and during the opening process, the resistance suffered by the cotton-beating roller is large, which easily damages the cotton-beating roller. Therefore, it is necessary to make a double-channel rough opener to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a double-channel rough opener to solve the problems mentioned in the background technique.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A double-channel rough opener, comprising a first frame, a first feeding mechanism, a first cotton-beating bin, a conveying bottom curtain, a second feeding mechanism, a second cotton-beating bin, a first cotton-sending fan and a cotton collecting box. The first cotton-beating bin includes a bin body housing, a first rotary driving assembly and a first cotton-beating roller. The bin body housing is fixed on the first frame and a first feeding port is provided on the right side. An opening is provided below the bin body housing. The first rotary driving assembly is fixed on the first frame. The first cotton-beating roller is rotatably installed on the first frame and corresponds to the left side of the first feeding port.

A second feeding port is opened on the right side of the second cotton-beating bin. The second feeding mechanism is fixed on the first frame and is respectively connected to the second feeding port and the conveying bottom curtain at the left and right sides. The right side of the first cotton-sending fan is communicated with the left side of the second cotton-beating bin. The cotton collecting box is communicated with the upper end of the cotton-sending fan through a pipeline. A plurality of groups of opening plates protruding radially are provided on the first cotton-beating roller. A hook portion is provided on one side of the opening plate facing the rotation direction. The opening plates are arranged in multiple rows along the length direction of the first cotton-beating roller, and the multiple rows of opening plates are spirally distributed along the length direction of the first cotton-beating roller.

[0007] Further description of the present invention: The first cotton-beating bin further includes a ventilation plate, which is fixed on the left side of the bin body housing, and a plurality of groups of ventilation holes are uniformly arranged on the ventilation plate.

[0008] Further description of the present invention: The first cotton-beating bin further includes a cotton guiding plate, which is fixed on the front and rear sides inside the bin body housing. The two groups of cotton guiding plates correspond to the upper side of the conveying bottom curtain and the right side of the second feeding mechanism, and the right side of the cotton guiding plate is inclined outward.

[0010] Further description of the present invention: A dust filtering assembly for filtering dust is provided in the cotton collecting box.

[0011] The beneficial effects of the present utility model are as follows: The fiber cotton material is conveyed into the first cotton beating bin through the first feeding mechanism. The first rotary drive assembly drives the first cotton beating roller to rotate counterclockwise. The hook part of the loosening plate on the first cotton beating roller hooks and tears the fiber cotton material and throws it leftward from above the first cotton beating roller along the rotation direction of the first cotton beating roller. The fiber cotton material after the first loosening falls on the conveying bottom curtain and continues to be conveyed leftward, and is fed into the second cotton beating bin from the second feeding mechanism. The second cotton beating roller is driven to rotate by the first cotton beating roller through a synchronous belt, and the rotation direction of the second cotton beating roller is also counterclockwise. The second cotton beating roller loosens the fiber cotton material for the second time and throws it from above the second cotton beating roller. Under the action of the first cotton feeding fan, the cotton material after two times of loosening is conveyed to the cotton collecting box through a pipeline. The cotton material in the cotton collecting box is put into subsequent equipment for processing through manual transportation or pipeline transportation. The advantage of this design is that two cotton beating rollers are used for two times of loosening to improve the effect of rough loosening. On the other hand, multiple rows of loosening plates are spirally distributed along the length direction of the first cotton beating roller. When hooking and tearing the cotton material conveyed by the first feeding mechanism, the loosening plates in the same row hook and loosen in sequence instead of the whole row hooking and tearing simultaneously, which can effectively reduce the resistance received by the first cotton beating roller during loosening, improve the loosening efficiency and service life of the first cotton beating roller.
