Description

Technical Field

[0001] The invention relates to the technical field of combing equipment, in particular to a combing blending equipment for high-temperature resistant flame-retardant protective fabrics and a combing process thereof. Background Art

[0002] With the rapid development and application of combing machines, the product quality and operation efficiency of combing machines have been generally improved. As a key process for yarn quality control, various indicators such as yarn evenness CV value, cotton neps and short fiber content rate are strictly controlled. During the long-term operation of combing machines, due to improper process design, inadequate maintenance and inspection, deformation of equipment parts, and aging of combing equipment, the process design data is inaccurate, which leads to quality fluctuations.

[0003] Chinese invention patent publication number CN115896989B discloses a combing machine for flame-retardant fabrics. The problem raised in its background technology is that due to the large number of combing needles, when adjusting the spacing between them according to needs, it is necessary to disassemble and adjust the large number of combing needles one by one, which makes the operation more cumbersome. By moving one end of the X-shaped movable frame, the guide groove can also limit the combing needles, and the other end of the X-shaped movable frame is limited by a limit sleeve, so that when the width of the X-shaped movable frame changes, the spacing between the combing needles can be adjusted. However, it has the following problems:

[0004] It adjusts multiple combing needles through an X-shaped movable frame. Although it limits the two ends of the X-shaped movable frame, it does not have a locking structure, and does not limit the hinge in the middle of the X-shaped movable frame. Due to the characteristics of the X-shaped movable frame itself, the X-shaped movable frame is prone to looseness and offset during long-term use, thereby affecting the stability of adjusting the combing needles, and further affecting the combing effect. In addition, the combing needles will deform during long-term use, affecting the combing effect. It does not have a structure for detecting the deformation of the combing needles. In the prior art, staff usually perform inspections through visual observation during regular maintenance. The inspection effect is poor and there are certain deficiencies. In order to solve the above problems, a combing blending device for high-temperature resistant flame-retardant protective fabrics and a combing process thereof are proposed. Summary of the Invention

The stability of the first guide block 329 and the combing needles 37 is improved while the adjustment is performed;

[0096] S2: During the adjustment process, the adjustment component 32 drives the self-locking component 38 to move, thereby self-locking the adjusted position of the combing needles 37. Since the spacing of the combing needles 37 is adjusted by the longitudinal movement of the adjustment plate 323, the self-locking component 38 limits the adjustment plate 323 in the longitudinal direction, thereby improving the stability of the combing needles 37 after adjustment, thereby avoiding affecting the combing effect. In addition, the position of the first guide block 329 is limited by the limiting component 36, further improving the stability of the combing needles 37 after adjustment.

[0097] S3: After the adjustment is completed, the linkage between the adjustment component 32 and the self-locking component 38 is disconnected through the connecting component 34, so that the self-locking component 38 uses a purely mechanical method to self-lock the combing needle 37, thereby preventing the self-locking effect from being affected by electrical failures such as the cylinder 31 and improving the stability of the self-locking.

[0098] S4: After the adjustment is completed, the raw material of the high-temperature resistant flame-retardant protective fabric is conveyed through the roller group 2. The roller group 2 includes a feed roller group 2 and a discharge roller group 2. The raw material enters the inner side of the machine body 1 from the feed roller group 2 and is conveyed to the outside of the machine body 1 through the discharge roller group 2. During the conveying process, that is, when the raw material is at the bottom of the combing needle 37, the cylinder 31 drives the combing needle 37 to move downward to contact the raw material, thereby combing it;

[0099] S5: After the combing needle 37 has worked for a certain period of time or the combing is completed, the detection component 39 is used to detect whether the combing needle 37 has been deformed, so as to facilitate the next combing use and the actual detection by the staff.

[0100] In step S1, the adjustment component 32 adjusts the distance between the combing needles 37 to match the raw material specifications of the high-temperature resistant flame-retardant protective fabric.

[0101] At the same time, the contents not described in detail in this specification belong to the existing technology well known to those skilled in the art.
