Description

Automatic cloth cutter

Technical field

The present invention relates to a kind of cutting machinery, relate in particular to a kind of automatic cloth cutter.

Background technology

Cloth is used more and more widely in commercial production as a kind of textile material, and use amount is also quite big, and therefore, the process efficiency of manual fabric dividing in the past is low, and accuracy to size is poor, can't satisfy growing use amount; And cloth has certain retractility; In case the pulling force that in cutting the cloth process, cloth is applied changes; Then cloth will produce different deformation; Cause the cloth accuracy to size after the last cutting low, present automatic cloth cutter is not kept the mechanism of constant pulling force mostly, so the cutting effect is relatively poor.

Summary of the invention

The present invention provides a kind of cutting effective automatic cloth cutter for solving the prior art problem.

Technical scheme of the present invention is: automatic cloth cutter; Comprise the anterior cloth feeding mechanism and the cloth cut device at rear portion; Cloth feeding mechanism the place ahead is provided with pre-distribution agency; Said pre-distribution agency comprises prime feed preparation unit roller that is arranged at the pre-distribution agency upper-end front and the transiting rod that is arranged at the pre-distribution agency upper rear; Pre-distribution agency also is provided with the cloth monitoring probe, and said cloth monitoring probe comprises the only cloth probe that cloth is popped one's head in and is arranged at middle part, pre-distribution agency lower end that advances that is arranged at the pre-distribution agency upper center.

Supply cloth mechanism to supply one section cloth in advance, can not produce pulling force to preceding end-grain cutting cloth when making cloth roll put cloth, the cloth that supplies in advance falls between transiting rod and the prime feed preparation unit roller; Receive signal when advancing the cloth probe, the cloth that promptly supplies in advance uses in the time of will using up, and advances the cloth probe and sends instruction; The operation of prime feed preparation unit roller obtains cloth from cloth roll, receives signal when ending the cloth probe; When the cloth length that promptly supplies in advance reaches a certain amount of, end the cloth probe and send instruction, the prime feed preparation unit roller is out of service; Through the combination of prime feed preparation unit roller with back level feed preparation unit roller, evenly work feed makes cloth receive constant pulling force all the time, and the deformation of cloth is constant all the time, makes cloth measure-alike of all cutting-outs.

As preferably, saidly advance the cloth probe and be infrared probe, and end of probe is downward; The said cloth probe that ends is infrared probe, and end of probe upwards; Saidly advance the cloth probe and end the cloth probe to be arranged on the position near the central vertical line of prime feed preparation unit roller and transiting rod line.Cloth is in cutting process, and the cloth that supplies in advance reduces, and the sagging minimum point of cloth increases; When the sagging minimum point of cloth and advance distance between the end of probe of cloth probe and be decreased to when a certain amount of, advance the cloth probe and detect signal, the cloth that supplies in advance is about to use up; The prime feed preparation unit roller brings into operation, and obtains cloth from cloth roll, and the cloth that supplies in advance is sagging under the gravity effect; The sagging minimum point of cloth reduces, and when minimum point and distance between the end of probe of ending the cloth probe are decreased to when a certain amount of, end cloth and pops one's head in and detect signal; The cloth that supplies in advance is more, and the prime feed preparation unit roller is out of service.

As preferably, a back level feed preparation unit roller is installed on the rag cutter frame of cloth cut device, and the rag knife in the cloth cut device is a chopper, and rag knife is arranged at the rear of back level feed preparation unit roller, and an end of rag knife is articulated in the rag cutter frame.The otch that the rag knife of chopper structure produces is more straight, and precision is higher.

As preferably, said prime feed preparation unit roller also is provided with stroke cylinder with the top of back level feed preparation unit roller, and said stroke cylinder can be controlled prime feed preparation unit roller and back level feed preparation unit roller upper and lower translation.Stroke cylinder can be according to the different-thickness of different clothes; The upper-lower position of adjustment prime feed preparation unit roller and back level feed preparation unit roller; The constant pressure that prime feed preparation unit roller and back level feed preparation unit roller are produced cloth; The frictional force that produces is constant, has guaranteed that the suffered pulling force of cloth in the work feed process is constant, makes the size of cutting more accurate.

As preferably; The below of said prime feed preparation unit roller and back level feed preparation unit roller is provided with the prime that matches with prime feed preparation unit roller and back level feed preparation unit roller respectively and cooperates roller and back level to cooperate roller, and said prime feed preparation unit roller, back level feed preparation unit roller, prime cooperate roller and back level to cooperate the outer surface of roller to be provided with silica gel layer.What cooperate roller is arranged so that the frictional force that the cloth upper and lower surfaces receives in the work feed process is equal and constant, guarantees the stable of work feed process; The roller on silica gel surface can not skid cloth in course of conveying, further guarantee the stable of work feed process.

As preferably, said cloth feeding mechanism is provided with slide bar, and said slide bar is provided with adjustable spacing ring.Spacing ring makes cloth in course of conveying, keep straight.

The length of the cloth that level feed preparation unit roller in back is confirmed through the number of turns that rolls across to carry, when the length of the cloth of conveying meets the demands, the time-out conveying, rag knife downcuts cloth;

In sum, the present invention has the following advantages:

1, cloth suffered pulling force in course of conveying is constant, constant deformation, and the size of cutting is accurate, good cutting effect;

2, cloth is straight in course of conveying, stable, and conveying and cutting speed are fast.
