Abstract
The utility model discloses an offset press damping conductivity alarm device, damping water return circuit department installation conductivity sensor, conductivity sensor electricity are connected to central controller, central controller electricity connection display screen and alarm lamp, report to the police when the conductivity value surpasss the normal scope of settlement, play suggestion and warning user's effect to help the snap judgments trouble reason, the rejection rate of printing that can significantly reduce practices thrift raw and other materials such as paper, printing ink.
Description
Technical Field
The utility model belongs to printing production control field, concretely relates to damping system to offset printing process carries out conductivity monitoring alarm's device.
Background
Offset printing requires a dampening system to provide a special "dampening water" to the press to wet the plate. The "dampening water" circulating in the dampening system contains mainly water, dampening solution, alcohol and impurities such as ink brought back from the printing press during printing. Whether the dampening water meets the requirements of the printing machine or not directly influences the quality of printed products after printing. Conductivity values are an important parameter for fountain water, and only fountain water that meets a certain range of conductivities is suitable for printing.
The existing dampening system has no conductivity monitoring function, and the dampening state monitoring is mainly realized by visual inspection of printing quality by printing personnel. When the quality of the printed product is found to be in a problem due to dampening water by visual inspection, whether dampening equipment works normally or not needs to be checked, possible reasons are gradually checked, and then a fault can be judged and maintained, so that huge waste of raw materials such as paper, printing ink and the like and working hours is inevitably caused.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide an offset press damping conductivity alarm device of automatic suggestion damping water quality reports to the police.
In order to solve the technical problem, the utility model discloses a technical scheme be: a dampening conductivity alarm device of an offset press is characterized in that a conductivity sensor is installed at a dampening water loop and electrically connected to a central controller, and the central controller is electrically connected with a display screen and an alarm lamp.
Preferably, the dampening water loop is further provided with a pH value sensor, and the pH value sensor is electrically connected to the central controller.
Implement the utility model discloses technical scheme can real-time supervision and show the conductivity value of fountain water, reports to the police when the conductivity value surpasss the normal scope of settlement, plays suggestion and warning user's effect to help the snap judgments trouble reason, the rejection rate of printing that can significantly reduce practices thrift raw and other materials such as paper, printing ink.

Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1, the offset press dampening plate conductivity alarm device mainly comprises a conductivity sensor 1, a central controller 3 and an alarm lamp 5.
The conductivity sensor 1 is arranged in a water loop 2 of the dampening system and is connected with the control device through a signal line; the water loop 2 is a part of a water pipeline of the dampening system, water in the water loop 2 is always in a flowing state, and the water quality is consistent with that of a water storage tank of the dampening system. The central controller 3 is a central controller of the dampening system, receives an electric signal from the conductivity sensor, and controls the display screen 4 and the alarm lamp 5 to operate. Display screen 4 installs in casing operating panel, shows real-time pH value and alarm information. The alarm lamp 5 is installed at a position where the cabinet is easily observed, and the operation is controlled by the central controller 3.
When the measured conductivity value is lower than the set lower limit, the central controller controls an alarm lamp 5 to give an audible and visual alarm, a display screen 4 displays the measured conductivity value, prompts a user to give an alarm on the lower limit of the conductivity value, and prompts possible reasons and inspection operation, such as whether the fountain solution adding function of a fountain system is normal or not; when the measured conductivity value is higher than the set upper limit, the central controller controls the alarm lamp 5 to give an audible and visual alarm, the display screen 4 displays the measured conductivity value, prompts a user to give an alarm at the upper limit of the conductivity, and prompts possible reasons and inspection operations, such as water changing and cleaning of dampening equipment.
As shown in fig. 2, the conductivity sensor 1 is composed of a probe 1.1, a transmitter 1.2 and a housing 1.3, wherein a signal output end of the probe 1.1 is connected with an input end of the transmitter 1.2, the probe 1.1 and the transmitter 1.2 are installed in the housing 1.3, and a top end of the housing is connected with an electric wire.
The transmitter comprises a DC/DC converter, a signal processing unit and a signal transmission unit, wherein the input end of the DC/DC converter is connected with a 12-24V direct-current power supply, the output end of the DC/DC converter is supplied with the power supply of the signal processing unit, the input end of the signal processing unit is connected with the signal output end of the probe 1, and the output end of the signal processing unit is connected with the input end of the signal transmission unit.
The shell is made of corrosion-resistant engineering plastics, the engineering plastics comprise PVC or PPS, and NPT tapered threads are arranged at the bottom of the shell, so that the equipment is convenient to mount on a pipeline.
The surface of conductivity sensor probe is provided with the oil-proof layer, and the oil-proof layer is formed by waterproof medicine material preparation, can make conductivity sensor probe have good waterproof performance, oil proofness and wearability, can prevent that the greasy dirt in the dampening environment from causing the influence to conductivity sensor probe, promotes the measurement numerical value accuracy.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
