Automatic fine-tuning control device for roller spacing bearded needle relative positions

Abstract

The invention discloses an automatic fine-tuning control device for roller spacing bearded needle relative positions. The automatic fine-tuning control device comprises a loosening machine, a conveying component and at least two claw rollers, wherein the loosening machine is used for loosening and scattering a regular fiber raw material; the conveying component is used for conveying the fiber; theat least two claw rollers are arranged on the loosening machine for loosening and scattering the fiber; the claw rollers are connected with a driving device through a rotary shaft; the claw rollers are provided with the automatic fine-tuning control device for the bearded barb relative positions; the automatic fine-tuning control device comprises a bilateral fine-tuning control device and a vertical fine-tuning control device which are arranged on the claw rollers; the bilateral fine-tuning control device and the vertical fine-tuning control device are arranged in a staggered way in order toadjust the roller pitch of the claw rollers; the fiber is further loosened by adjusting the relative distance of roller on the claw rollers. By adopting the automatic fine-tuning control device, the relative distance of the roller barbs on the claw roller is fine-tuned through the fine-tuning roller, so that good fiber loosening effect, good fiber filling power are achieved; the fiber is looseneduniformly, and the finished product quality is ensured.

Description

technical field [0001] The invention relates to the field of PTFE needle-punched felt, in particular to an automatic fine-tuning control device for the relative position of rollers and crochet needles. Background technique [0002] PTFE needle felt dust bag is a fiber with extremely stable chemical properties. Its characteristics are as follows: 1. Good air permeability:   Air permeability is an important indicator to measure the performance of filter materials. The air permeability of polytetrafluoroethylene (PTFE) film-coated filter material can reach 3-6m3 / ㎡·min, which has exceeded the actual use requirements. 2. Wide adaptability to the use environment: Polytetrafluoroethylene (PTFE) film-coated filter material has high and low temperature resistance, anti-condensation and chemical stability, and no aging properties, which determine its extreme resistance to temperature, humidity and corrosive gases. Strong adaptability, especially for high-concentration, high-humidity,...

Problems solved by technology

(2) singeing

[0004] In view of the above process, during the fiber opening process, the fiber blocks are fed into the carding process without sufficient opening, which directly affects the uniformity of the cotton web, resulting in the formation of cloud spots on the surface of the final finished felt, with poor uniformity , varying in thickness

[0005] In addition, in the process of fiber opening, sometimes the fiber will be blocked between the licker-in roller and the conveying device or too much fiber will be wound on the licker-in roller, so that the fiber will not be completely opened, and the fiber will block the discharge port and cannot be blown. come out

[0006] The above two problems mainly have the problems of uneven fiber opening and inconsistent thickness of fiber mixing, resulting in insufficient fiber fluff, which affects the subsequent operation steps
