Abstract

The utility model relates to a loom with a novel hot cutter in an optimal position, which belongs to the field of a loom in textile industry and is suitable for application of a trademark loom. The utility model provides the loom with the novel hot cutter in the optimal position, and the purpose is to reduce cutting error and ensure cutting quality. The novel hot cutter is installed in the position which reduces the distance between a cutting point and a force receiving point before the width of figured cloth is not changed or has less change. The loom with the novel hot cutter in the optimal position is composed of a machine frame, a drive system, a figure braiding system and the hot cutter. The utility model is characterized in that the hot cutter (13) is installed on the machine frame (12) in the cloth conveying roller (2), the hot cutter is composed of a fixing body (7), electrodes (8, 9) and a cutter body (10), wherein the cutter body cuts the figured cloth at the outlet (14) of the cloth conveying roller, or the cutter body is arranged at the outlet (15) of a turning plate (3).

Description

A kind of loom of the novel hot knife in the optimum position

Technical field:

The loom of a kind of novel hot knife in the optimum position of utility model belong to textile industry the loom field, be fit to the application of trademark loom especially.

Background technology:

The loom classification is a lot, and the trademark loom of weave trade marking is wherein arranged, and it comprises frame, transmission system, self-figure system and hot knife.Trade mark comprises literal, color, pattern or their combination, so trade mark cloth can be described as figured cloth.

Total fabric width that each Tianwan businessman marks loom cloth comprises the identical trade mark of many groups, they are linked to be together, so will be cut to single trade mark figured cloth to a whole cloth branch, cut by the cutting knife that is installed on the loom, cutting knife adopts hot knife usually, cutting essence is that so the hot knife cutter hub is exactly a heater, heater can adopt heating wire, laser, laser apparatus with the heat yarn that fuses.

Yarn just becomes figured cloth after loom is finished the longitude and latitude braiding, figured cloth enters feed preparation unit roller 2 (Fig. 2) and wraps up the roller surface from the below immediately, draw from the top of feed preparation unit roller then, behind deflecting plate 3, pass through axle 1 (4) and axle 2 (5) successively, the hot knife (13) that is installed in this moment between axle 1 and the axle 2 is cut figured cloth, and the figured cloth after cutting batches (Fig. 1) by work beam 6.

After figured cloth leaves feed preparation unit roller and deflecting plate, can produce the phenomenon that fabric width changes, the situation that figured cloth produces this phenomenon has two kinds.

First, we know, the internal force of figured cloth can be with the yarn material, the undaform density that produces during warp knitting, the density of parallel are different and variant, in order to weave different patterns, pattern, figured cloth graticule density everywhere is inequality, so figured cloth suffered internal force everywhere is different, different internal force can make the figured cloth fabric width change.But there is Buddha's warrior attendant sand on the surface of trademark loom feed preparation unit roller, and by husky promptly its surface of Buddha's warrior attendant, the internal force of having kept figured cloth is constant, so the figured cloth fabric width between feed preparation unit roller and deflecting plate is forced to and can not changes immediately for the figured cloth that has just woven.But after deflecting plate, the external force that figured cloth is firmly grasped by Buddha's warrior attendant sand is cancelled, so the figured cloth fabric width can be with different variation of suffered power everywhere.

The second, after the cutting, figured cloth internal force is damaged, and cloth produces the power of inwardly shrinking, and the power of contraction is different, and figured cloth fabric width minification is also different.Distance dependent in the figured cloth between convergent force and point of contact and the stressed fulcrum of figured cloth, this distance is big, and figured cloth fabric width minification is big, so all point of contacts are not on the straight line of same warp, there is lateral separation front and back between the point of contact, form cutting error.

Above-mentioned two kinds of situations make the figured cloth fabric width neglect little neglecting greatly, and figured cloth just looks like in cutting knife front move left and right, and the point of contact is departed from, and has produced cutting error, and figured cloth edge, cutting back is irregular, even exceeds standard, causes waster.

Existing hot knife is that axle 1 is the stressed fulcrum of figured cloth between axle 1 and axle 2, and is bigger to the distance of cut point with axle 1.

From last analysis as can be known, 3 cause influence cut quality are arranged, the one, figured cloth is (Fig. 1) after leaving feed preparation unit roller and deflecting plate, because of the figured cloth internal force balance is damaged, the fabric width of cloth can change.The 2nd, distance also influences cut quality between cut point and the stress point.The 3rd, yarn material, pictorial trademark.For blanket brand, thirdly be hard and fast, therefore to improve cut quality from first and second reason.Promptly to before also having little time to change, cut the figured cloth amplitude broad or reduce distance between cut point and the stress point.

Summary of the invention:

The utility model provides a kind of loom of the novel hot knife in the optimum position, its objective is the minimizing cutting error, guarantees cut quality.

The utility model adopt the figured cloth fabric width do not change or few the variation before and the position that dwindles distance between cut point and the stress point new hot knife is installed.

A kind of loom of the novel hot knife in the optimum position, contain frame, transmission system, self-figure system and hot knife, it is characterized in that hot knife is installed on the frame of feed preparation unit roller position, hot knife is by fixed body, and electrode and cutter hub are formed, cutter hub and figured cloth are tangent in the feed preparation unit roller exit, or cutter hub is positioned at the deflecting plate exit.

Hot knife as mentioned above, fixedly physical efficiency is rotated.

Aforesaid hot knife, the fixed body top end face has compressing member.

The utility model is simple in structure, installs easy to adjustly, has improved cut quality greatly.

Fig. 3 is novel hot knife vertical view.

Fig. 4 is that novel hot knife is installed in the frame schematic diagram.

Fig. 5 is that hot knife is installed the optimum position schematic diagram.

1, figured cloth 2, feed preparation unit roller 3, deflecting plate 4, axle 15, axle 26, work beam 7, fixed body 8, positive electrode 9, negative electrode 10, cutter hub 11, screw 12, frame 13, hot knife 14, feed preparation unit roller export the outlet of 15 deflecting plates

The specific embodiment:

With object lesson explanation this programme.

Fig. 5 shows it is the optimum position that hot knife is installed: hot knife 13 is installed in feed preparation unit roller outlet 14 or deflecting plate 3 outlets 15

Fig. 2,3 has shown the structure of hot knife 13: it is made up of fixed body 7, positive electrode 8, negative electrode 9, cutter hub 10.This routine cutter hub is a heating wire, and it is fixed between the positive and negative electrode (8,9).

Fig. 4 is novel hot knife scheme of installation, and fixed body 7 is installed in the hole of frame 12, and it can rotate, and the top end face of fixed body compresses with screw 11.

Single, easy to adjust between this exemplary construction, reduce labour intensity, improve cut quality.
