Description

Technical Field

[0001] The utility model belongs to the technical field of printing equipment, and discloses a leakage and air leakage detection system for a printing machine. Background Art

[0002] In modern industrial production, printing machines are widely used in the production process of various printed products. The normal operation of printing machines has an important impact on production efficiency and product quality. However, printing machines often face potential safety hazards such as electric leakage and air leakage during operation. These hazards may not only lead to equipment failures and production interruptions, but also electric leakage and air leakage may even cause serious accidents such as fires, threatening the lives of workers. Therefore, real-time detection and early warning of the electric leakage and air leakage conditions of printing machines have become important measures to ensure printing production safety.

[0003] Traditional printing machine safety monitoring systems usually rely on manual inspections or simple alarm devices, and this method has the following problems:

[0004] 1. Detection is not timely: Manual inspections are intermittent and cannot achieve real-time monitoring of printing machines, easily missing early warning signals of electric leakage or air leakage, resulting in the expansion of faults.

[0005] 2. Detection accuracy is low: Simple alarm devices often can only provide relatively rough fault information and cannot accurately locate the specific position of electric leakage or air leakage, increasing the difficulty of maintenance.

[0006] 3. Information transmission is not smooth: Traditional monitoring methods often lack a systematic information transmission mechanism and cannot convey fault information to relevant personnel in a timely manner, delaying the timing of fault handling.

[0007] Based on the above problems, there is an urgent need for an intelligent monitoring system that can detect the electric leakage and air leakage conditions of printing machines in real time and accurately, and give early warnings in a timely manner. Content of the Utility Model

[0011] The gas detectors are arranged above the burners on the printing machine, the leakage detection ammeter is arranged on the metal cabinet door panel of the distribution box, and a printing machine serial port server is arranged in the signal line aggregation box body;

[0012] The data collected by the gas detector and the leakage detection ammeter is transmitted to the printer computer terminal through the printer serial server, and the printer computer terminal is connected to the central control terminal, which is used to control the system operation.

[0013] In some embodiments, the gas detector is installed on the printer through an L-shaped mounting plate. The gas detector is located directly above the burner, with its detection end facing downwards and towards the burner.

[0014] In some embodiments, mounting holes are provided on the cabinet door panel. The leakage detection ammeter is provided with a locking hook, and a locking buckle is provided on the other side of the cabinet door panel. The leakage detection ammeter passes through the mounting hole and is installed on the cabinet door panel under the cooperation of the locking hook and the locking buckle.

[0015] In some embodiments, the surface of the cabinet door panel is grounded.

[0016] In some embodiments, the printer computer terminal is connected to the central control terminal through a switch.

[0017] In some embodiments, the central control terminal is connected to the display terminal, and the display terminal is a display board that displays the operation status of the system.

[0018] In summary, the beneficial effects of the present utility model are as follows:

[0030] To deepen the understanding of the present utility model, the present utility model will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present utility model and do not constitute a limitation to the protection scope of the present utility model.

[0031] As Figure 1-6 shown, a leakage and gas leakage detection system for a printing press includes a printing press 1, a distribution box 2, a plurality of gas detectors 3 provided on the printing press 1, a leakage detection ammeter 4 provided on the distribution box 2, and a signal wire aggregation box body 5 provided on the printing press 1.

[0032] Among them, the printing press 1 is placed on the workshop floor and is used for printing operations on printing paper 4. The printing press 1 in this embodiment is a gravure printing press.

[0033] The distribution box 2 is arranged on one side of the printing press 1 and is used to supply electrical energy to the printing press 1 and provide overall control for the printing press 1.

[0034] During the printing process, in order to make the ink better adhere to the printing medium, a heater is required, and the heating part of the heater needs to use a burner 6. Generally, gas is used for combustion heating. The gas detector 3 is arranged above the burner 6 on the printing press 1 and is used to detect whether there is gas leakage at the burner 6, ensuring a safe production environment.

[0035] For large equipment such as the printing press 1, the distribution box 2 is generally powered by strong electricity. The leakage detection ammeter 4 is arranged on the metal cabinet door panel 7 of the distribution box 2, which can effectively monitor the leakage situation of the distribution box 2 and prevent accidents caused by miscontact of staff during leakage.

[0036] The signal line aggregation box body 5 is fixed on the printing machine 1. Signal lines of a number of gas detectors 3 and leakage detection ammeters 4 are all connected into the signal line aggregation box body 5. A printing machine serial server 8 is arranged in the signal line aggregation box body 5. The gas detectors 3 and the leakage detection ammeters 4 transmit the detected data to the printing machine computer terminal 9 through the printing machine serial server 8. The printing machine computer terminal 9 transmits the collected detection data to the central control terminal 10 through a switch 15. The central control terminal 10 is responsible for integrating and processing the data so that the staff can understand the operation status of the equipment at any time.

[0037] In a preferable implementation manner, the gas detector 3 is mounted on the printing machine 1 through an L-shaped mounting plate 11 and fixed by a number of screws. The gas detector 3 is located directly above the burner 6. The detection end of the gas detector 3 faces downward and faces the burner 6.

[0038] In order to detect the gas leakage state of the printing machine more accurately, the detection end of the gas detector 3 in this embodiment is arranged downward and mounted on a common gas leakage point through an L-shaped mounting plate, improving the detection efficiency of gas leakage.

[0039] Furthermore, an installation hole 12 is formed in the cabinet door panel 7. A locking hook 13 is arranged on the leakage detection ammeter 4. A locking buckle 14 is arranged on the other side of the cabinet door panel 7. The leakage detection ammeter 4 passes through the installation hole 12 and is mounted on the cabinet door panel 7 under the cooperation of the locking hook 13 and the locking buckle 14.

[0040] The cabinet door panel 7 is a metal door panel. When the equipment is leaking electricity, there will also be an electric current passing through the door panel. The leakage detection ammeter 4 can detect whether there is an electric current passing through the cabinet door panel 7 and the magnitude of the electric current, ensuring the safety of the production environment.

[0041] A grounding wire is connected to the cabinet door panel 7. The grounding wire is connected to a grounding stake to prevent personal injury caused by electric leakage.

[0042] As another implementation manner of further optimization, the central control terminal 9 is connected to the display terminal 16. The display terminal 16 is a display board for displaying the operation situation of the system.

[0043] The display board is used for displaying the working state of the printing machine 1, located in the factory display area or can also be located in the office area, facilitating the staff to be able to see the operation state of the printing machine 1 at any time so as to troubleshoot faults at any time and improve the printing quality.
