the working principle and beneficial effects of the technical scheme are as follows: the long-term code spraying operation is carried out, the first conveyor belt and the second conveyor belt are likely to be stained with ink sprayed by code spraying equipment, through the arrangement of the conveyor belt cleaning equipment, water flow and ultrasonic waves generated by the miniature water pump and the ultrasonic transducer can be conveyed to the first brush head and the second brush head through pipelines, and the width of the first brush head and the width of the second brush head are matched with the size of the first conveyor belt and the size of the second conveyor belt, so that the first conveyor belt and the second conveyor belt can be cleaned. The flexible backing material is discharged from the rear side of the workbench surface and from the front side; the cleaning equipment is arranged on the front side of the workbench surface, and the height of the cleaning equipment is not higher than the upper surface of the conveyor belt, so that the fabric discharging can not be blocked. The cleaning device only cleans a small part of the strip-shaped surface of the front side of the conveyor belt close to the workbench, and the surface of the conveyor belt is also beneficial to drying in the process from front operation to back operation after the surface is cleaned. And the widths of the first brush head and the second brush head are equal to the sizes of the first conveyor belt and the second conveyor belt, and the code spraying area of the gap is not affected.
The embodiment of the invention also provides an automatic coding method of the code spraying machine, which comprises the following steps:
s1, conveying flexible base materials to a designated position of a working platform through a conveyor belt;
s2, the visual recognition device recognizes the surface pattern of the flexible base material, a set code spraying area is selected, a plurality of alternative code spraying positions are sequentially determined from front to back along a conveyor belt gap in the area, the position coordinates of each alternative code spraying position are sequentially recorded, and the position coordinates are transmitted to the control system;
the control system controls the code spraying device to move to the first alternative code spraying position for carrying out the code spraying mark according to the front-back sequence of the position coordinates of the alternative code spraying positions;
s3, the control system controls the solidification and drying device to solidify and dry the spray-printed mark, and the spray-printing is completed;
s4, after the code spraying is finished, the flexible base material is sent out of the working platform through a conveyor belt;
the working principle and beneficial effects of the technical scheme are as follows: the invention is mainly applied to the flexible backing material for producing bedding articles, taking the gathered cotton as an example, the surface of the flexible backing material is provided with a plurality of gathered cotton threads, the surface of the flexible backing material is provided with various patterns, and the area with the gathered cotton threads is not suitable to be selected when the pattern is sprayed; after the flexible base material is conveyed in place, the visual recognition device recognizes the surface through various preset patterns, selects a proper code spraying range, recognizes a plurality of proper code spraying positions from front to back along the fabric transmission direction in the area, sets code spraying position coordinates, transmits the coordinates to the control system, and the control system automatically moves to a preferred code spraying position according to the position coordinates to finish automatic code spraying; after the code is sprayed, the code spraying position is solidified and dried by the solidifying and drying device, so that the code text sprayed and printed can be quickly dried and fixed.
In one embodiment, the automatic coding method of the code spraying machine, step S3 further includes:
s31, the control system controls the code reading detection device to read codes of the solidified and dried identifications, and detects whether the identifications are identifiable or not;
if the mark can be identified correctly, the detection is qualified, and the code spraying is finished;
if the identification is not identifiable, detecting failure; the control system controls the code spraying device to move to the position coordinate of the next alternative code spraying position to carry out the code spraying mark again according to the front-back sequence of the position coordinate of the alternative code spraying position;
and detecting whether the mark is identifiable again until the detection is qualified, and finishing code spraying.
The working principle and beneficial effects of the technical scheme are as follows: after the code-spraying text is dried and fixed, in order to ensure that the code-spraying text can be clearly and correctly identified, the code-reading detection device is utilized to carry out code-reading self-inspection on the code-spraying text, after the self-inspection is qualified, the whole set of code-spraying operation is completed, and the flexible base material is sent out from the workbench surface; if the self-checking is unqualified, the code spraying, curing and drying and code reading self-checking actions are automatically repeated at other proper code spraying positions. Therefore, the ink is not permeated and diffused on the surface of the flexible backing material, and pollution to the flexible backing material is avoided; and the clear and identifiable code text after spray printing can be ensured.
In one embodiment, the automatic coding method of the code spraying machine, step S31 further includes:
when the number of detection failures of the same flexible primer jet printing the same mark exceeds a threshold value, the code reading detection device gives an alarm to a control system, and the control system turns off the code spraying machine to stop code spraying operation.
The working principle and beneficial effects of the technical scheme are as follows: because the proper code spraying position on the surface of the flexible base material is limited, if the code spraying position is still unable to be detected to be qualified after the code spraying for many times, the code spraying position which possibly does not meet the requirement is used for the automatic code spraying of the code spraying machine; at the moment, the control system is reminded to close the code spraying machine through an alarm function, automatic operation is stopped, and workers are reminded to perform manual intervention and inspection; after the position is manually adjusted, the automatic code spraying operation is started.
In one embodiment, the ink jet printer automatically codes, preferably,
in the S2 step, the visual recognition device only determines the position coordinates of two alternative code spraying positions, and the control system controls the code spraying device to move to the first alternative code spraying position for carrying out code spraying identification according to the front-back sequence of the position coordinates of the alternative code spraying positions;
in the S31 step, whether the identification is identifiable or not is detected, if the identification is not identifiable, the detection fails; controlling the code spraying device to move to the position coordinate of the second alternative code spraying position to carry out the code spraying mark again; detecting whether the mark is identifiable again, if not, failing to detect;
the code reading detection device records the number of times of detection failure as two, the code reading detection device gives an alarm to the control system, and the control system closes the code spraying machine to stop the code spraying operation.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
