Concrete block coding device

Abstract

The invention discloses a concrete block coding device which comprises a base, a driving part fixedly arranged on the left side of the base and a positioning module fixedly arranged on the right side of the base. The positioning module is provided with a plurality of through holes which are combined to form a printing code shape, the base is further provided with a telescopic module in a horizontal sliding mode, and the telescopic module is provided with a plurality of engraving needles corresponding to the through holes; the telescopic end of the driving piece is connected with the telescopic module so as to drive the marking needle of the telescopic module to slidably penetrate through the through hole in a matched mode. The base is further provided with a controller, a first inductive switch and a second inductive switch, and the controller is in electric signal connection with the driving piece, the first inductive switch and the second inductive switch. According to the concrete block coding device, marking is conducted on the surface of a semi-finished product in a dotted character forming mode, accumulated materials on the marking needle can be automatically removed, ink, diluent and other consumables are not needed, the consumables and the cost are saved, and the concrete block coding device has the advantages of being simple in mechanism, reliable in action, convenient to maintain and the like.

Description

technical field [0001] The invention relates to the technical field of concrete block preparation, in particular to a coding device for concrete blocks. Background technique [0002] Existing aerated concrete blocks need to be marked and coded according to national standards when they are sold (the contents are generally product strength marks and company logos). The coding equipment generally uses automatic inkjet printers. This type of equipment mainly uses the inkjet printing function , under the control of the microcomputer computer program, the ink in the ink tank is sprayed on the surface of the moving block in the form of dots according to the set words through the dense needle nozzle by using compressed air to form a coding mark. When using an automatic inkjet printer for coding, the dust in the finished brick output area of ​​the aerated concrete block production plant is generally large, and the diameter of the nozzle nozzle of this type of automatic inkjet printer...

AI Technical Summary

Problems solved by technology

When using an automatic inkjet printer for coding, the dust in the finished brick output area of ​​the aerated concrete block production plant is generally large, and the diameter of the nozzle nozzle of this type of automatic inkjet printer is relatively small, and the ink exists in the nozzle. It is easy to solidify, and the dusty environment on site can easily cause nozzle blockage, making the ink unable to print normally. The ink used in this type of inkjet printer is generally customized and sold by the inkjet printer manufacturer. To solve this problem, it is necessary to purchase a matching set at the same time. The ink thinner is blended and used, and other inks cannot be used for normal printing or even fail. Because the ink and thinners for this type of inkjet printer are expensive and the amount is large, long-term purchase of consumables is very important for the production of aerated concrete blocks. It is a big expense for the manufacturer; and the maintenance of the nozzle is troublesome, and it cannot be repaired after being blocked. It needs to be sent back to the inkjet printer manufacturer with special equipment for clearing and repairing, which brings a lot of inconvenience to the maintenance work and increases the maintenance cost.
