Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile processing technology, specifically to a surface cleaning mechanism for suede processing. Background Technology
[0002] Knitted weft-knitted suede is a type of artificial suede fabric made using weft knitting technology combined with special finishing processes (mainly napping). It successfully mimics the look and feel of suede leather while possessing the elasticity, softness, and breathability of knitted fabrics. It is a popular fabric widely used in clothing, shoes, bags, and home furnishings.
[0003] In the knitted weft-knitted suede processing technology, the suede fabric undergoes finishing processes such as napping and shearing to obtain a uniform pile. However, the processing process generates a large amount of loose floating hair and lint, requiring the suede surface to be cleaned to make it smoother and ensure that the suede surface is clean and free of residual floating hair.

[0014] (III) Beneficial Effects
[0015] This utility model provides a surface cleaning mechanism for processing cowhide suede. It has the following beneficial effects:
[0016] 1. In this utility model, the rotation of the pressure regulating motor can push the pressure regulating plate to move back and forth, thereby changing the overlapping area between the pressure relief port and the pressure regulating port, thus changing the ventilation area. The suction power generated by the suction tube can be dynamically and smoothly adjusted, and the suction power can be enhanced in stages. Compared with the existing constant pressure suction, it can avoid the surface air resistance formed by constant pressure, which hinders the fiber gaps. The staged pressurization allows the airflow to gradually break through the resistance layer at different depths, achieving all-dimensional cleaning.
[0017] 2. While removing loose hair and lint, the air pressure is gradually controlled by the pressure slope to keep the fabric tension in a low range, thus avoiding irreversible deformation caused by constant pressure hair suction being kept under high pressure. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] This utility model embodiment provides a surface cleaning mechanism for suede processing, such as... Figure 1-2As shown, the device includes, from front to back, a suction fan 1, a pressure regulating mechanism, a dust collection box 2, a ventilation pipe 3, and a lint suction pipe 4, with a lint suction port on the side wall of the lint suction pipe 4.
[0023] The pressure regulating mechanism includes a pressure regulating box 5, a pressure regulating motor 6, and a pressure regulating plate 7. The pressure regulating box 5 is hollow inside. The front and rear sides of the pressure regulating box 5 are connected to connecting sleeves 8. A filter screen 9 is installed in the connecting sleeve 8 on the rear side. The connecting sleeves 8 on the front and rear sides are respectively connected to the suction fan 1 and the dust collection box 2. The negative pressure generated by the suction fan 1 passes through the pressure regulating box 5, then through the dust collection box 2 and the ventilation pipe 3, forming a suction pressure at the suction port of the suction pipe 4. This pressure acts on the surface of the suede processing, sucking away the loose hair and lint, which then enters the dust collection box 2.
[0024] The pressure regulating box 5 has a sliding guide rail on its upper side, and a limit beam is provided on the front side of the sliding guide rail. The pressure regulating plate 7 is slidably installed in the sliding guide rail. The output end of the pressure regulating motor 6 is connected to the pressure regulating screw 10, and the pressure regulating plate 7 is threadedly connected to the pressure regulating screw 10. The upper side wall of the pressure regulating box 5 has a circular pressure relief port 11. The pressure regulating plate 7 includes an integrally formed connecting part and a sealing part. The connecting part has a conical pressure regulating port 12. The front and rear sides of the conical pressure regulating port 12 are provided with semi-circular holes of different sizes. The inner diameter of the semi-circular hole on the front side is equal to the inner diameter of the pressure relief port 11, and the inner diameter of the semi-circular hole on the rear side is smaller than the inner diameter of the pressure relief port 11. When the pressure regulating plate 7 is behind the sliding guide rail, the semi-circular hole on the front side of the pressure regulating port 12 coincides with the circular pressure relief port 11. At this time, the internal area of the pressure regulating box 5 is most connected to the outside. The air pressure of the suction fan 1 after passing through the pressure regulating box 5 is at its lowest value. As the pressure regulating plate 7 slides forward, the area of the pressure relief port 11 gradually increases, and the air pressure after passing through the pressure regulating box 5 gradually increases. The length of the sealing part is greater than the inner diameter of the pressure relief port 11, and the sealing part can completely seal the pressure relief hole, so that the hair suction pressure reaches the maximum value, thereby realizing the staged pressurization of the hair suction air pressure. In addition, the shape of the pressure regulating port 12 and the pressure relief port 11 is defined so that the change of ventilation area is fluctuating, thereby making the increase and decrease of air pressure uneven, that is, generating a pulse-like fluctuating air pressure, which can further impact the suede and clean the suede more thoroughly. However, compared with the strong impact of the pulse, the impact method of this application is gentler, avoiding the fabric damage caused by the pulse, and keeping the suede surface flat after hair suction cleaning.
[0025] A connecting beam 13 is fixed to the front side of the pressure regulating plate 7. A pressure regulating nut 14 is fixed to the side of the connecting beam 13 facing the pressure regulating screw 10. The pressure regulating nut 14 is threadedly sleeved on the pressure regulating screw 10. A guide rod 15 parallel to the pressure regulating screw 10 is provided on the upper side of the dust collection box 2. A guide hole is opened on the side of the connecting beam 13 corresponding to the guide rod 15. The guide hole is slidably sleeved on the guide rod 15. A displacement sensor 16 is fixed to the front side of the pressure regulating plate 7. The displacement sensor 16 is electrically connected to the pressure regulating motor 6. The displacement sensor 16 can control the forward and reverse rotation of the pressure regulating motor 6. Thus, the pressure regulating plate 7 can slide back and forth in the extension direction of the pressure regulating screw 10 through the threaded engagement, thereby realizing the gradual adjustment of the suction air pressure.
[0026] Working principle:
[0027] In this invention, the airflow gradually breaks through the resistance layer at different depths through a gradual, staged pressurization, achieving full-dimensional hair removal and cleaning. At the same time, compared with the hair removal process that maintains a constant high pressure, the gradual pressure regulation hair removal in this application is more energy-efficient.
[0028] In addition, the pressure regulating mechanism in this utility model can also control the pressure regulating plate 7 to be in a fixed position, thereby adjusting the suction air pressure to maintain a certain pressure, so as to meet the cleaning needs of cowhide suede processing surfaces with different weight differences.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
