Abstract

The utility model discloses a cloth expanding device. The cloth expanding device comprises a faller chain, a hairbrush wheel group and a cloth expanding assembly, wherein the faller chain is provided with a plurality of needle blocks; the needle blocks are provided with positioning needles for fixing testing cloth, directions of threads at two sides of each cloth expanding screw rod are opposite, and the width of the testing cloth is adjusted inward or outward simultaneously along the axial direction of the screw rods. According to the utility model, through guiding of the hairbrush wheel group, strip testing cloth is fixed on the positioning needles of needle blocks, the tensioning degrees of the testing cloth on the two sides of the cloth expanding device are respectively regulated by shaking hand wheels arranged on left and right sides, after proper adjustment is achieved, a star-shaped handle is screwed, the tensioning quantity is locked, and cloth expanding chain wheels of the cloth expanding assembly are matched with the faller chain to realize feeding movement in a transmission direction; the smooth and correct reproduction of tissue of the testing cloth is achieved by applying tension through a faller frame.

Description

Widening device

Technical field

The utility model discloses a kind of widening device, by International Patent Classification (IPC) (IPC), divides and belongs to cloth dyeing drying plant manufacturing technology field.

Background technology

Examination cloth (cloth) belongs to precise materials, especially, for the knitwear of retractility, requires to have correct tissue after test, yet, try at present the restriction of cloth due to the tension force accessory, do not reach above-mentioned requirements after test.

Summary of the invention

For the deficiencies in the prior art, the utility model provides a kind of widening device, gives tension force by pin frame and reaches, and the smooth correct tissue of examination cloth reproduces.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of widening device, comprise needle plate chain, hairbrush wheels and expand the cloth assembly, wherein:

The needle plate chain, it forms pin frame side by side by two groups, and some pin pieces are installed on each needle plate chain, has the pilot pin of fixing examination cloth on the pin piece;

The hairbrush wheels, it is placed in needle plate chain top and forms the directive wheel that examination cloth is fixed on the pin piece;

Expand the cloth assembly, it comprises expansion cloth sprocket wheel, expands the cloth screw rod and expands the cloth nut, described expansion cloth screw rod is two pairs and all is furnished with the cloth of expansion nut, wherein the nut of a pair of expansion cloth screw rod is connected with the assembling of expansion cloth sprocket wheel by ball bearing, expand the cloth sprocket wheel and coordinate with the needle plate chain feed motion that realizes transmission direction, described each expansion cloth screw rod both sides ridge is on the contrary, simultaneously inside or outside along screw axial when examination cloth wide cut is adjusted.

Further, described expansion cloth assembly also comprises handwheel and star grip knob, this handwheel and star grip knob be placed in respectively before and after the needle plate chain side and respectively with wherein one expand the cloth screw rod and be connected and try the cloth tensioning degree to regulate both sides.

Further, described expansion cloth screw rod is comprised of pair of sprocket screw rod and pair of inside screw rod, one sprocket wheel screw rod coordinates with an inboard screw rod and two ends are arranged on bearing block, be provided with connecting plate between sprocket wheel screw rod and the inboard screw rod coordinated, the key way fixed mount is installed between two inboard screw rods, and the key way fixed mount is provided with guide rail.

The utility model characteristics are as follows:

1. in widening device, used the both sides ridge to contrary two couples expansion cloth screw rod and the expansion cloth nut matched, when examination cloth wide cut is adjusted, simultaneously inside or outside along screw axial;

2, the left and right sides all disposes and expands the cloth nut, so left and right sides wide cut can be adjusted respectively;

3, expand the cloth sprocket wheel and be arranged on and expand on the cloth nut by ball bearing, the rotation of expanding the cloth sprocket wheel can not affect expands the cloth nut, therefore can not affect the examination cloth wide cut that adjusted puts in place.

Fig. 2 is that the utility model expands cloth assembly schematic diagram;

Fig. 3 is the inboard screw rod schematic diagram of the utility model;

Fig. 4 is the utility model sprocket wheel screw rod schematic diagram.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Embodiment: refer to Fig. 1 to Fig. 4, a kind of widening device, comprise needle plate chain 1, hairbrush wheels 2 and expand cloth assembly 3, wherein:

Needle plate chain 1, it forms side by side by two groups, and some pin pieces 10 are installed on each needle plate chain, has the pilot pin of fixing examination cloth on the pin piece;

Hairbrush wheels 2, it is placed in needle plate chain top and forms the directive wheel that examination cloth is fixed on the pin piece;

Expand cloth assembly 3, it comprises expansion cloth sprocket wheel 31, expands the cloth screw rod and expands cloth nut 33, described expansion cloth screw rod is two pairs and all is furnished with the cloth of expansion nut 33, wherein the nut 33 of a pair of expansion cloth screw rod is connected with 31 assemblings of expansion cloth sprocket wheel by ball bearing 34, expand the cloth sprocket wheel and coordinate with the needle plate chain feed motion that realizes transmission direction, described each expansion cloth screw rod both sides ridge is on the contrary, simultaneously inside or outside along screw axial when examination cloth wide cut is adjusted.

Refer to Fig. 2, Fig. 3 and Fig. 4, expansion cloth assembly of the present utility model also comprises handwheel 35 and star grip knob, this handwheel and star grip knob be placed in respectively before and after the needle plate chain side and respectively with wherein one expand the cloth screw rod and be connected and try the cloth tensioning degree to regulate both sides.Described expansion cloth screw rod is comprised of pair of sprocket screw rod 321 and pair of inside screw rod 322, one sprocket wheel screw rod coordinates with an inboard screw rod and two ends are arranged on bearing block 36, be provided with connecting plate 37 between sprocket wheel screw rod and the inboard screw rod coordinated, key way fixed mount 38 is installed between two inboard screw rods, and the key way fixed mount is equipped with guide rail 39.

The utility model course of work is as follows:

1. by the guiding of hairbrush wheels, billot examination cloth is fixed on to (the pin piece is arranged on the needle plate chain) on pin piece pilot pin;

2. by shaking the handwheel of the left and right sides, regulate respectively the tensioning degree of both sides examination cloth, after adjusting to the right place, screw star grip knob, the locking amount of tension;
