Description

PTFE base cloth rolling straining device

Technical Field

The utility model belongs to the technical field of PTFE base cloth production facility technique and specifically relates to a PTFE base cloth rolling straining device is related to.

Background

PTFE, namely polytetrafluoroethylene, is one of the highest varieties in the bag type filter material, a filter bag made of PTFE base cloth can be used for flue gas treatment in the processes of coal-fired boilers, garbage incineration, carbon black production, titanium dioxide production and the like, and also has application in the processes of primary smelting, refining and chemical production of some metals, and the PTFE base cloth needs to be dyed in the production process.

The PEFT base cloth often can appear relaxing and drag ground when the rolling, just so lead to the rolling inefficacy, and current equipment can only be along with cloth tension along with the tight of tension through installation tight pulley on equipment, and when the cloth was lax, the yardage roll on the wind-up roll also can be followed laxly, and the cloth on the wind-up roll still can appear lax phenomenon this moment to cloth rolling inefficacy reduces work efficiency.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: in order to solve the problem that the existing equipment can only tension along with the tension degree of the cloth width by installing a tension pulley on the equipment, when the cloth width is loosened, the cloth roll on the winding roller can also be loosened along with the cloth width, and the cloth width on the winding roller still can be loosened at the moment, so that the cloth width is failed to be wound, and the working efficiency is reduced, a PTFE base cloth winding and tensioning mechanism is provided at present.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a PTFE base cloth rolling straining device, includes the frame and sets up the wind-up roll in the frame, be provided with straining device in the frame, straining device includes tensioning roller, slide and connecting rod, the tensioning roller rotates and sets up on the connecting rod, the articulated setting of connecting rod is on the slide, mutual parallel arrangement between tensioning roller and the wind-up roll, one side that the wind-up roll was kept away from to the connecting rod is provided with first spring, the slide sets up in the frame along the radial slip of wind-up roll, be provided with the second spring between frame and the slide, the slide is located between wind-up roll and the second spring.

The utility model discloses a slide and set up the slide in the frame to articulated the connecting rod on the slide, set up tensioning roller and base cloth laminating simultaneously in the one end of connecting rod, make the base cloth on the wind-up roll tensioning state always appear like this, can drive the slide along with the increase of base cloth rolling diameter on the frame displacement simultaneously, tensioning roller and cloth width of cloth laminating and tensioning on the first spring plays the connecting rod of keeping throughout, and the second spring plays the effect that the slide replied to initial displacement.

In order to realize the displacement of the sliding plate on the rack, further, a linear guide rail is arranged on the rack along the displacement direction of the sliding plate, a sliding block matched with the linear guide rail is arranged on the sliding plate, and the sliding block is arranged on the linear guide rail in a sliding manner. The linear guide rail on the machine frame is matched with the sliding block on the sliding plate, so that the sliding plate can move on the machine frame.

In order to adjust the displacement range of the sliding plate, a screw rod and a limiting nut are further arranged on the rack along the displacement direction of the sliding plate, a through hole is formed in the sliding plate, one end of the screw rod penetrates through the through hole and is in threaded connection with the limiting nut, and the limiting nut is located at one end, far away from the second spring, of the sliding plate. Through set up the screw rod in the frame to rotate limit nut, thereby change the displacement scope of slide, just also satisfy the requirement of different diameter wind-up rolls.

In order to better guarantee that the base cloth on the winding is tensioned, the number of the tensioning rollers is two, and the two tensioning rollers are oppositely arranged on two sides of the winding roller. Through set up dual tensioning in the both sides of wind-up roll, better assurance is better carries out the tensioning to the base cloth on the rolling.

The utility model has the advantages that: the utility model discloses PTFE base cloth rolling straining device is when using, set up the slide through sliding in the frame, and articulated the connecting rod on the slide, the one end at the connecting rod has set up tensioning roller and base cloth laminating simultaneously, make the base cloth on the wind-up roll tensioning state always appear like this, can drive the slide along with the increase of base cloth rolling diameter on the frame displacement simultaneously, first spring plays and keeps the tensioning roller on the connecting rod and cloth laminating and tensioning all the time, the second spring plays the effect that the slide replied to initial displacement, avoided existing equipment to pass through on equipment the tight pulley of installation and can only be along with cloth rate of tension tensioning, when the cloth appears lax, the yardage roll on the wind-up roll also can follow lax, the cloth on the wind-up roll still can appear lax phenomenon this moment, thereby the winding that the cloth became invalid, reduce work efficiency's problem.
