Description

TECHNICAL FIELD

[0001] The utility model relates to the field of printed fabric, especially an automatic deviation rectifying device. BACKGROUND

[0002] In the prior art, when printing, the printed fabric is tightly attached to the rubber guide belt and does not move because of the pre-applied adhesive on the rubber guide belt. After printing, the fabric enters the drying device, and the printed fabric is separated from the rubber belt. The polyester guide belt rotates by the driving roller, and the fabric is stably attached to the polyester guide belt by the pressure of the hot air nozzle and enters the drying room for drying.

[0003] The existing conveying device cannot guarantee absolute parallelism between the driving roller and the driven roller when conveying the fabric, and left and right deviation inevitably occurs. At this time, the position of the fabric often needs to be adjusted manually to prevent deviation and return to the normal transmission track. Manual intervention may cause the worker to be in a dangerous area, which may cause injury to the worker. SUMMARY

[0004] The automatic deviation rectifying device provided by the present application can automatically correct the fabric if deviation occurs when the conveying device conveys the fabric in the prior art, avoiding the problem that manual adjustment of the position of the fabric may cause the worker to be in a dangerous area, which may cause injury to the worker.

[0005] The technical solutions adopted by the present application are as follows.

[0006] An automatic deviation rectifying device includes a support, a first plate arranged on one side of the support, a second plate arranged on the other side of the support, a guide roller for guiding the fabric, a connecting piece connecting the end faces of the guide rollers, and an adjusting device for adjusting the angle of the guide roller. The guide roller is provided with two groups. The connecting piece is provided with four groups in opposite positions. The adjusting device is arranged on the second plate, and the adjusting device is arranged on the second plate. The working end of the adjusting device is connected to the connecting piece.

[0007] As a further improvement of the above technical solution, the adjusting device includes a third plate, a first hinge point arranged on the third plate, and a pushing piece hingedly connected to the second plate. The pushing end of the pushing piece is connected to the first hinge point. The third plate is provided with two groups of connecting pieces.

[0008] As a further improvement of the above technical solution, a first slot adapted to the guide roller is formed in the second plate. The diameter of the first slot is greater than the diameter of the guide roller.

[0009] As a further improvement of the above technical solution: the second plate is provided with a fourth plate; the fourth plate is L-shaped; the fourth plate is provided with a first limiting block; the first limiting block is provided with two groups opposite to the fourth plate; the third plate is provided with a guide wheel; the guide wheel is provided with four groups; two groups of the guide wheel abut against the upper fourth plate, and the other two groups of the guide wheel abut against the lower fourth plate; the upper fourth plate is provided with a second limiting block; the guide wheel is located between the first limiting block and the second limiting block.

[0010] The one or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0011] 1. The support is an integral frame, and the two sides of the support are provided with a first plate and a second plate. The first plate is provided with two groups of connecting pieces connected to the end face of the guide roller. The second plate is provided with a fourth plate, which is L-shaped. The fourth plate is provided with two groups opposite to each other. The fourth plate is provided with a first limiting block located on the inner side of the fourth plate. The second plate is hingedly connected with a pushing piece, which is a pneumatic cylinder. The driving end of the pushing piece is connected with a third plate. The third plate is provided with a first hinge point connected to the acting end of the pushing piece. The third plate is rotatably connected with a guide wheel, which is provided with four groups. The lower two groups of the guide wheel are in contact with the lower fourth plate, and the upper two groups of the guide wheel are in contact with the upper fourth plate. The upper fourth plate is provided with a second limiting block. The guide wheel is located between the first limiting block and the second limiting block. The second plate is provided with a first slot adapted to the guide roller. The diameter of the first slot is greater than the diameter of the guide roller. Thus, the pushing piece drives the third plate to move, thereby adjusting the angle of the guide roller, so that the position of the fabric changes until it is located on the normal transmission track. The automatic deviation correcting device proposed in the embodiments of the present application can drive the two deviation correcting rollers to move in the opposite direction of the deviation of the fabric when one of the left and right sensors senses the deviation of the fabric during the transmission of the fabric on the mesh belt. The other end of the roller is supported and fixed by the universal bearing and can be angularly rotated to make the deviation correcting roller move left or right, thereby gradually correcting the fabric. When the fabric deviates again, the above-mentioned operation is repeated to automatically correct the fabric. Compared with the traditional manual deviation correction or electric deviation correction, the embodiments of the present application can obtain the direction of deviation through the sensor, drive the roller to tilt left or right through the cylinder, and achieve the automatic deviation correction of the fabric, thereby achieving the change of the position of the fabric until it is located on the normal transmission track.
