Problems solved by technology

[0003] In the PVC / PU production process, the traditional precision coating head needs manual operation to complete the knife jumping and reset actions when the release paper joint is close to the coating knife. Due to the operator's operation and various uncertain factors, the knife is often jammed and broken paper production accident
Every time there is a knife jam accident, it has to be stopped to collect materials and pick up paper. During this period, nearly 100 meters of leather are scrapped due to long-term baking in the oven, resulting in great waste.
Moreover, due to the different production processes of PVC / PU, the moving speed of PVC / PU will vary from 10 m / min to 35 m / min, so it is difficult to control the coating of PVC / PU by manual operation. The exact time of knife take-off and reset will not be able to control the length of waste leather produced each time when the knife is taken off and reset, which will also cause waste of materials caused by inaccurate movements

Embodiment 1

[0025] like figure 1 As shown, a PVC / PU coating knife automatic knife jumping and reset control device includes a color sensor 1 for detecting the release paper joint; a sensor for detecting the movement distance of PVC / PU and generating a pulse corresponding to the movement distance A pulse generator 2; a first counter 4 and a second counter 3 for counting the pulses; a first relay 6 for controlling the work of the coating knife lifting device; and a first relay 6 for controlling the work of the coating knife falling device Two relays 5; the color mark sensor 1 is electrically connected with the first counter 4, the second counter 3 and the pulse generator 2 respectively, and the pulse generator 2 is electrically connected with the first counter 4 and the second counter 3 respectively, so The first counter 4 is electrically connected to the first relay 6 , and the second counter 3 is electrically connected to the second relay 5 .

[0026] In this embodiment, the PVC / PU coati...

Embodiment 2

[0034] like Figure 5 As shown, this embodiment is a method corresponding to the automatic jumping of the PVC / PU coating knife and the reset control device in the first embodiment. The method comprises the following steps: S1, judging whether to detect the joint of the release paper; S2, generating a pulse corresponding to the moving distance when the joint of the release paper is detected; S3, counting the pulse by the first counter and the second counter ; S4. Judging whether the first counter overflows, if yes, control the coating knife to start; S5, judging whether the second counter overflows, if yes, control the coating knife to fall; S6, end.

[0035] In this embodiment, the pulses are respectively connected to the first counter and the second counter through an integral distributor.

[0036] In this embodiment, the color mark sensor is an infrared emitting and receiving sensor.

[0037] In this embodiment, the pulse is generated by a Hall sensor, and a magnetic subst...

Abstract

The invention discloses a device and method for automatic tool tripping and reset control over a PVC / PU coating tool. The device comprises a color mark sensor, a pulse generator, a first counter, a second counter, a first relay and a second relay, wherein the color mark sensor is used for detecting release paper connectors, the pulse generator is used for detecting the moving distance of PVC / PU and generating pulses corresponding to the moving distance, the first counter and the second counter are used for carrying out counting on the pulses, the first relay is used for controlling a coating tool lifting up device to work, and the second relay is used for controlling a coating tool dropping down device to work. The color mark sensor is respectively and electrically connected to the first counter, the second counter and the pulse generator, the pulse generator is respectively and electrically connected to the first counter and the second counter, the first counter and the first relay are electrically connected, and the second counter and the second relay are electrically connected. The device for automatic tool tripping and reset control over the PVC / PU coating tool is stable in working performance and high in precision, and greatly reduces material waste.

Description

technical field [0001] The invention relates to a coating knife control device and a method thereof, in particular to a PVC / PU coating knife automatic jumping and reset control device and a method thereof. Background technique [0002] PVC / PU artificial leather is based on a special paper (commonly known as release paper) as a carrier. PVC or PU slurry is divided into 2 to 3 layers and scraped on the surface of the release paper, dried or foamed with hot air in an oven, and then It is formed by laminating the cloth with the dried and formed coating with a laminating material. In the production process, due to the different product structures, the release paper must be cut and spliced ​​with colored high-temperature tape to produce a release paper joint. Before the PVC / PU and the release paper are peeled off, they pass through the guide wheel and the cooling wheel synchronously between the oven and the precision coating head in the nearly 100-meter-long assembly line equipme...
