Abstract

The invention discloses a device for automatically tracking the tension of a post treatment production line of synthetic leathers, comprising a rotating shaft (8), a rotating shaft swing arm (7), a cloth guide roller (9) and a mounted bearing. A cylinder swing arm (3) is installed at the external end of the rotating shaft (8) and connected with a cylinder (5); a big sprocket wheel (12) is also installed at the external end of the rotating shaft (8) and connected with a small sprocket wheel (11) through a chain (1), and the small sprocket wheel (11) is installed on an angular displacement device (2). Through the index display on the angular displacement device, the running speed of a painted rubber roller is adjusted and controlled so that the cloth guide roller moves towards the left direction or the right direction, and the tension of the synthetic leather is automatically tracked to realize accurate tensioning with favorable tensioning effect, thereby lateral displacement and position deviation do not occur when the synthetic leather is conveyed, the color paste is uniformly coated and the coloring quality of the synthetic leather is improved.

Description

The device for automatically tracking tension of post treatment production line of synthetic leather

One, technical field

The present invention relates to a kind of post treatment production line of synthetic leather, specifically relate to a kind of device that synthetic leather is carried out tensioning control that is applied to post treatment production line of synthetic leather.

Two, background technology

Post treatment production line of synthetic leather is the production equipment of repeatedly tinting and dry in a kind of surface to natural leather or dermatine, by unreel, tensioning, tint, device such as oven dry, rolling constitutes, wherein tensioning apparatus only is made of rotating shaft, rotating shaft swing arm, fabric guide roll, rolling bearing units etc., tensile force to synthetic leather can not well be controlled, tension effects is relatively poor, cause the transverse shift, position sideslip of synthetic leather and to go up mill base inhomogeneous, influenced the quality of tinting of synthetic leather.

Three, summary of the invention

The object of the invention is to overcome above-mentioned deficiency, and a kind of device for automatically tracking tension that can carry out the tension force of synthetic leather from the post treatment production line of synthetic leather of motion tracking, good control is provided.

Purpose of the present invention realizes by following technical solution: a kind of device for automatically tracking tension of post treatment production line of synthetic leather, comprise rotating shaft, rotating shaft swing arm, fabric guide roll and rolling bearing units, in the outer end of described rotating shaft the cylinder swing arm is housed, the cylinder swing arm links to each other with cylinder; Hinge wheel also is equipped with in outer end in described rotating shaft, and hinge wheel links to each other with minor sprocket by chain, and this minor sprocket is contained on the angular displacement device.In described rotating shaft, balance weight and weight compensating piece also are housed by counter-jib.

After adopting structure of the present invention, show that the rubber roll speed of service of tinting of regulating and control this production line makes fabric guide roll do motion to the left or to the right, synthetic leather tension force is carried out realizing accurate tensioning from motion tracking, and tension effects is good by the pointer on the angular displacement device.Thereby synthetic leather can not produce transverse shift, position sideslip when carrying, last mill base is even, has improved the synthetic leather quality of tinting.

Four, description of drawings

The present invention is described in further detail below in conjunction with accompanying drawing and embodiment.

Fig. 1 is the device for automatically tracking tension structural representation of post treatment production line of synthetic leather of the present invention.

Fig. 2 is the right view (and the rubber roll of tinting, drying room fabric guide roll, drying room crossbeam are housed) of Fig. 1.

Fig. 3 is the left view (and the rubber roll of tinting, drying room fabric guide roll, drying room crossbeam are housed) of Fig. 1.

Fig. 4 is that the B of the angular displacement device among Fig. 1 is to view.

Five, the specific embodiment

Referring to figs. 1 through Fig. 3 as can be known, the device for automatically tracking tension of post treatment production line of synthetic leather of the present invention, comprise rotating shaft 8, rotating shaft swing arm 7, fabric guide roll 9 (tensioning with) and rolling bearing units (comprising rotating shaft rolling bearing units 6 and roller strap seat bearing 10), in the outer end of described rotating shaft 8 cylinder swing arm 3 is housed, cylinder swing arm 3 (by bearing pin 4) links to each other with cylinder 5; Hinge wheel 12 also is equipped with in outer end in described rotating shaft 8, and hinge wheel 12 links to each other with minor sprocket 11 by chain 1, and this minor sprocket 11 is contained on the angular displacement device 2.(can be the outermost end place) and by counter-jib 14 balance weight 13 and weight compensating piece 15 are housed also in described rotating shaft 8, countershaft plays balanced action.

Wherein: angular displacement device 2, cylinder 5 all can be contained on the drying room crossbeam 16 of this post treatment production line of synthetic leather; Pointer 17 (as shown in Figure 4) also can be housed on the angular displacement device 2, and pointer also and then rotated (generally in 30 degree scopes) when minor sprocket rotated; According to installation requirement, cylinder swing arm 3 and cylinder 5, hinge wheel 12, chain 1, minor sprocket 11 can be positioned on the outer end, the same side of rotating shaft with angular displacement device 2, also can divide on the left and right sides outer end that is positioned at rotating shaft, Figure 1 shows that on same (right side) side outer end of rotating shaft; The rubber roll 18 of tinting of this post treatment production line of synthetic leather is equipped with in the below of fabric guide roll 9, and the tint variable-frequency motor of rubber roll 18 speeds of service of angular displacement device 2, cylinder 5, control all is electrically connected by its regulation and control with the microcomputer controller of this production line.

During work, synthetic leather 20 is wrapped on the rubber roll 18 of tinting, fabric guide roll 9 (tensioning) and the drying room fabric guide roll 19 successively.When the tension force of synthetic leather is not enough, pointer on the angular displacement device shows not in place, then variable-frequency motor is controlled the rubber roll 18 quickening speeds of service of tinting, make fabric guide roll 9 work as shown in Figure 2 to left movement (former) at illustrated dotted line position, the while cylinder push-rod stretches out the swing arm of promotion cylinder fabric guide roll is positioned support and synthetic leather is carried out tensioning, and make the rotating shaft rotation, drive hinge wheel, chain and minor sprocket work by rotating shaft again the pointer on the angular displacement device is rotated.Pointer on the angular displacement device shows when putting in place that the rubber roll 18 of then tinting keeps the speed of service constant, and cylinder quits work, and fabric guide roll stops swinging, and synthetic leather is realized tensioning.When the pointer on the angular displacement device shows when offside, the synthetic leather tensioning is excessive, variable-frequency motor control rubber roll 18 speed of service that slows down of tinting then, make fabric guide roll moving right as shown in Figure 2, cylinder push-rod is made contractile motion fabric guide roll is positioned support simultaneously, and synthetic leather is realized suitable, accurately tensioning, and makes the rotating shaft rotation, drive hinge wheel, chain and minor sprocket work by rotating shaft again the pointer on the angular displacement device is rotated, show until pointer to put in place.
