Description

Carpet inkjet printing machine with thickness detection device

Technical field:

The utility model relates to a structure of a textile printing device, in particular to a structure of a carpet printing machine with a thickness detection device.

technical background:

When the printing machine prints on the printing medium, ensuring the proper distance between the printing machine nozzle and the printing medium is a key point for the printing machine to produce high-precision patterns. Generally, different types of printing media have different thicknesses. If the proper distance between the nozzle of the printing machine and the printing medium cannot be maintained, the following problems will occur: 1. When the nozzle of the printing machine is too close to the printing medium, the nozzle Failure to obtain a suitable distance for spraying will cause the quality of the printed pattern to decline; if the nozzle of the printing machine is in contact with the printing medium, it will also cause damage to the nozzle or scrapping of the printing medium. 2. When the distance between the nozzle of the printing machine and the printing medium is large, the printed pattern will be blurred and imprecise.

Detailed ways:

According to Fig. 1 and Fig. 2, the thickness detection device of the present invention mainly includes a height detection bracket 2, a contact sensor 3, a height sensor 4 and a lifting pair 7.

The height detection bracket 2 spans above the conveyor belt frame 1 and the conveyor belt 5, and the two ends of the height detection bracket 2 are respectively provided with lifting pairs 7, and the lifting pairs 7 are installed on a bracket 6, and the brackets 6 are respectively fixed. On both sides of the conveyor belt frame 1; the lifting pair 7 is a turbine device, and is respectively provided with an independent motor 8 for driving. Also be provided with contact sensor 3 and height sensor 4 on height detection support 2, described contact sensor 3 is provided with several, and it is arranged on the range of height detection support 2 above conveyer belt 5, and equidistant is installed in height detection respectively on bracket 2. There are two height sensors 4 , which are respectively arranged at both ends of the height detection bracket 2 , and the height sensors 4 are placed on the end faces of both sides of the conveyor belt frame 1 .

The contact sensor 3 is also connected to the control circuit of the motor 8 to control the operation of the motor. When the contact sensor touches the printing medium, the contact sensor sends a signal to control the motor 8 to drive the lifting pair to rise. The contact sensor 3 is not in contact with the printing medium. If the printing medium is not touched, the contact sensor sends a signal to stop the motor. The height sensor 4 is connected to the control circuit on the print head frame, the height sensor sends out a signal representing the thickness of the printing medium, the control circuit detects the electrical signal from the height sensor, and adjusts the height of the print head frame after calculation.

When the printing machine is working, the printing medium is placed on the conveyor belt and conveyed through the height detection device. If the contact sensor 3 is in contact with the printing medium, the contact sensor 3 sends a signal to the motor control circuit to control the operation of the motor 8, and the motor drives the lift The auxiliary rises to drive the height detection bracket to rise. If the contact sensor 3 is always in contact with the printing medium, it keeps rising until the contact sensor does not contact the printing medium, then the contact sensor sends a signal to the motor control circuit, and the motor stops running. At the same time, the height sensor 4 installed on the height detection bracket 2 transmits the signal to the nozzle control circuit at the same time, and after the calculation by the nozzle control circuit, the height of the nozzle is controlled to keep the nozzle at a suitable distance from the printing medium.
