Filament bundle tension buffer device for chemical fiber production

Abstract

The invention discloses a filament bundle tension buffer device for chemical fiber production. The device comprises a rack. The rack comprises two support rods which are vertically arranged. The opposite side walls of the two support rods are symmetrically provided with two mounting grooves, wherein openings of the mounting grooves are opposite to each other. A mounting block is arranged in each mounting groove. A rotating shaft is connected to the side wall of each mounting block in a rotary manner through a rotating part, wherein each rotating shaft is transversely arranged. A filament feeding wheel is arranged between the two rotating shafts, wherein the filament feeding wheel is transversely arranged. Mounting holes are symmetrically formed in the side walls of the upper side and the lower side of each mounting groove, wherein openings of every two mounting holes are opposite to each other. Movable blocks are connected into the mounting holes in a sliding manner, wherein the movable blocks are vertically arranged. Inclined planes are symmetrically arranged at one end of each movable block, and the other end of each movable block penetrates the side wall of the corresponding mounting hole and is connected with a swing rod in a rotary manner. By means of the filament bundle tension buffer device for chemical fiber production, the phenomena that filament bundles are fracturedor wound due to sudden change of the tension in the conveying process can be effectively avoided, and the influence of springback of springs on stable filament feeding of the filament feeding wheel can be reduced.

Description

Technical field [0001] The invention relates to the technical field of chemical fiber spinning production equipment, in particular to a tow tension buffer device for chemical fiber production. Background technique [0002] At present, chemical fiber plays a very important role in life and industry. The use of recycled bottle flake spinning can not only solve the environmental pollution of polyester, but also realize the recycling of resources, thereby reducing energy consumption and reducing the chemical fiber industry's dependence on crude oil. More importantly, the use of recycled bottle flakes to weave polyester staple fiber has a very low cost and an obvious price advantage. In actual production, the conveying distance of the chemical fiber tow is very long, so it is easy to break and wrap due to the sudden change in tension. Therefore, it is necessary to design a buffer device to avoid sudden changes in the tension of the tow during the conveying process. In view of the phe...

Problems solved by technology

In actual production, the conveying distance of chemical fiber tow is very long, so it is easy to cause broken and entangled filaments due to sudden changes in tension. Therefore, it is necessary to design a buffer device to avoid sudden changes in tension during the conveying process of tows. Aiming at the phenomenon of the tow tension buffer device for chemical fiber production in the patent No. CN203889793U, a plurality of elastic parts arranged in the circumferential direction interfere with the shaft sleeve and the shaft hole, so as to buffer the sudden tension during transportation, but due to the multiple springs It is set in conflict with the shaft sleeve, so that during the buffering process, the aftershock of the spring will make the entire shaft sleeve shake continuously, which makes the wire feed roller not stable enough when feeding the wire.
