Abstract

The utility model provides a roller mechanism of a flat knitting machine and belongs to the technical field of knitting machinery. The roller mechanism of the flat knitting machine comprises transporting belts, an active roller, a passive roller, a V-shaped gap, a hairbrush and a micro switch, wherein the transporting belts are arranged oppositely and rotate in different directions, the active roller and the passive roller drive the transporting belts, the V-shaped gap used for knitted fabrics to penetrate through is formed between the transporting belts arranged oppositely, the rotatable hairbrush is arranged below the transporting belts, and the micro switch is used in match with the hairbrush. According to the roller mechanism of the flat knitting machine, point contact traction and line contact traction of the metal structure is changed into face contact traction, and stressed state of fabrics is improved by the face contact force under the situation of identical traction force. At the same time, the transporting belts are made of materials strong in flexibility like polyurethane materials, and cleanness and smoothness of the surface of the fabrics and maintenance of natural states like memory spaces are further improved.

Description

Roller of flat knitting machine mechanism

Technical field

The utility model relates to a kind of roller of flat knitting machine mechanism, belongs to the flat machine technical field.

Background technology

Machined needles woven garment and adornment are with the roller output procedure of knitted fabric after circle is moved back in lopping of computer flat knitting machine, that the knitted fabric that will form pulls out from knitting point, give the certain tension force of fabric, then send, because tractive affects very large on knitting cycle and product quality, generally will satisfy following basic demand: owing to knitting cycle carries out continuously, so the tractive motion also will continuously move; The tractive tension force that acts on each coil will stablize, evenly, unanimously; Tractive tension force, unit interval tractive amount are synchronous with lopping technique; The primary characteristic that keeps textile material is such as smoothness, anti-fracture energy, fibre space elasticity etc.

Yet, existing Knitting Machinery, such as computer flat knitting machine, its draw-off mechanism mainly is that Weight type, pecten formula, roller type, pin are brush, cam-type etc., all there is significant deficiency in the draw-off mechanism of these forms, at first, adopt the part of metal structure that fiber is exerted pressure, destroyed original performance of fiber; Secondly, the differential that the linear velocity of lopping process speed and the motion of tractive component surface causes forms mantle friction, makes fiber surface produce vaporific structure even fluffing; At last, the metal surface point, line local damage that pressure and the frictional force of fiber is very easily caused fiber surface and the change of fibrous inside natural structure, make fiber in the situation of its fracture strength license, radially spread attenuation, length direction stretcher strain, friction and point, linear pressure all in various degree destruction the serviceability of fiber.

Summary of the invention

The purpose of this utility model provides a kind of roller of flat knitting machine mechanism that overcomes defects.

The technical scheme that adopts for realization the utility model purpose is as follows:

Roller of flat knitting machine mechanism, comprise drive roll and driven roll, between drive roll and the driven roll conveyer belt is installed, article two, conveyer belt is for being oppositely arranged face-to-face, direction of rotation is opposite, article two, consist of " V " shape gap of passing for knitted fabric between the conveyer belt, below conveyer belt, be provided with rotating hairbrush, and the microswitch that is used with hairbrush.

The two ends of described drive roll are provided with the sleeve that is connected with initiative roll shaft, and two end supports are installed on the sleeve, are connected with the driven roll support between two end supports, and driven roll is located on the driven roll support.

The entrance two ends in described " V " shape gap are provided with the yarn guiding parts.

Described conveyer belt is made by polyurethane fiber.

Operation principle and the beneficial effect of the utility model roller of flat knitting machine mechanism are as follows:

1. adopt the opposite conveyer belt group tractive output fabric of direction of rotation in the face of arranging, point, the line contact tractive of metal structure are changed into face contact tractive, in the identical traction force situation, face contact pulling force has changed the stress concentration phenomenon of traction force to fiber, and the fiber that makes unit are is stressed reduces, and has greatly improved the stress of fiber;

2. conveyer belt adopts the strong materials of pliability such as polyurethane material, has further improved the maintenance of the natural forms such as any surface finish of fiber and memory headroom;

3. the entrance two ends in " V " shape gap are provided with the yarn guiding parts, can make things convenient for mechanical erection, and promote the tractive effect when producing;

4. when fabric was transmitted the roll coil of strip and lives together rotation situation, fabric just can touch hairbrush, and hairbrush can touch microswitch automatically after being subject to certain pressure, and whole system just can be sent the failure warning signal, thereby prevents better the generation of unexpected job failure.

Description of drawings

Fig. 1 is the partial structurtes cutaway view of the utility model roller of flat knitting machine mechanism;

Fig. 2 is the perspective view of the utility model roller of flat knitting machine mechanism.

Number in the figure: 1, left tray; 2, right carriage; 3, drive roll; 4, driven roll; 5, " V " shape gap; 6, yarn guiding parts; 7, sleeve; 8, two end supports; 9, driven roll support; 10, hairbrush; 11, microswitch; 12, conveyer belt.

The specific embodiment

Fig. 1,2 is the utility model roller of flat knitting machine mechanism, on left tray 1 and right carriage 2, drive roll 3 and driven roll 4 are installed, drive roll 3 and driven roll 4 are two pairs, between drive roll 3 and the driven roll 4 conveyer belt 12 is installed, the direction of rotation of the conveyer belt 12 between the two pairs of drive rolls 3 and the driven roll 4 is opposite, article two, consist of " V " shape gap 5 that supplies knitted fabric to pass between the conveyer belt 12, below conveyer belt 12, be provided with rotating hairbrush 10, and the microswitch 11 that is used with hairbrush 10.

Starting device, drive two drive rolls 3 and do the rotation of opposing parallel, and driving conveyer belt 12 rotates, change point, the line contact tractive of metal structure into face contact tractive, in the situation of identical traction force, face contact pulling force has changed the stress concentration phenomenon of traction force to fiber, thereby has changed significantly the stress of fiber.

The two ends of drive roll 3 are provided with the sleeve 7 that is connected with its roll shaft, sleeve 7 one ends are connected with the axle of drive roll 3, the other end is fixed in the drive roll 3, be provided with two end supports 8 on the

sleeve

7,8 of two end supports are connected with driven roll support 9, driven roll 4 is installed on this driven roll support 9, and guarantees to have kept between two driven rolls 4 space of opposing parallel.

The entrance two ends in " V " shape gap 5 are provided with yarn guiding parts 6, can play to the direction of fabric certain guiding and control action, thereby have kept well original shape of fabric.

Hairbrush 10 removable revolving, when 3 relative motion of two drive rolls, conveyer belt 12 also rotates thereupon, as fabric occurs be transmitted the roll coil of strip and live, fabric rotates with conveyer belt 12, and fabric just can touch hairbrush 10, can automatically touch the microswitch 11 of its below after hairbrush 10 is stressed, this moment the whole system caution signal that just can break down, thereby prevent better the generation of unexpected job failure.
