Abstract

The utility model discloses a safe ultraviolet drier, which aims to provide a safe ultraviolet drier which has the function of air draught detection and can automatically stop and make an alarm when exceptions happen. The utility model is characterized in that a machine is provided inside with a wind pressure switch, the negative pressure pipe of which is arranged on the inner wall of an outlet pipe, a signal output contact is connected with a machine controller, thereby when air draught and exhaustion exceptions happen, the utility model can timely detect the exceptions and simultaneously stops and makes an alarm to prevent machine accidents resulting from overheating. The utility model is used to dry printed matter.

Description

The safety-type ultraviolet drier

Technical field

The utility model relates to a kind of printing drying machine, and more particularly, it relates to a kind of ultraviolet drier.

Background technology

Ultraviolet drier, the UV that extensively is used in printings such as silk-screen, wire mark, flexo, a page or leaf printing coats with lacquer drying.But all there is bigger potential safety hazard in the employed ultraviolet drier of press at present, when following fault takes place in the exhausting system of board:

1. exhaust column all comes off on the board;

2. exhaust column partly comes off on the board;

3. board upcast ventilation pipe breakage;

4. the air exhauster not exhausting that breaks down.

When above-mentioned situation takes place, board can because of exhausting inadequately or not exhausting cause in the board temperature too high, and the board fault takes place, can cause that also printed matter is overheated and on fire when serious, thereby cause fire.

Summary of the invention

The purpose of this utility model is to provide a kind of has the exhausting measuring ability, the safety-type ultraviolet drier that but autostop is also reported to the police under the abnormal conditions is taking place.

The purpose of this utility model is to be achieved by following technical scheme.

Safety-type ultraviolet drier of the present utility model comprises board, is contained in the interior inner cover of board, is installed in the discharge pipe on the inner cover, the air exhauster that is contained in air outlet tube mouth, blast switch, and described blast switch is located on the interior inner cover of board; The port of the negative pressure pipe that blast switch is drawn is arranged on the discharge pipe inwall; Signal output contact on the blast switch is connected with the gauge tap of board by lead.

Adopt the ultraviolet drier of utility model, but have advantage safe in utilization, that abnormal conditions autostop and warning take place.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Among the figure: board 1 inner cover 2 discharge pipes 3 air exhausters 4 blast switch 5

Negative pressure pipe 51 signal output contacts 52 stators 6

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done to describe further.

Fig. 1 is the utility model a kind of specific embodiment wherein.

As shown in fig. 1, safety-type ultraviolet drier of the present utility model is on the basis of existing ultraviolet drier, increases wind pressure detection device; The concrete practice is that the right-hand member of the discharge pipe 3 on the inner cover 2 in board 1 is fixed a stator 6, is used for installing and fixing blast switch 5; The negative pressure pipe 51 of drawing on the blast switch 5 is installed on the inwall of discharge pipe 3, and the signal output contact 52 on the blast switch 5 is connected by the gauge tap of lead with board 1; Negative pressure pipe 51 is in air exhauster 4 operate as normal, under the intact situation of discharge pipe 3, can produce certain negative pressure, and blast switch 5 is opened; It is normal at this time to control current signal output; And when following situation takes place:

1. exhaust column all comes off on the board;

2. exhaust column partly comes off on the board;

3. board upcast ventilation pipe breakage;

4. the air exhauster not exhausting that breaks down;

Blast in the discharge pipe 3 can change, and the negative pressure in the negative pressure pipe 51 will reduce, and blast switch 5 can't be opened, and the control current signal is undesired, thereby makes the gauge tap deenergization of board 1 and warning simultaneously.So just can prevent that board 1 is because of the overheated accident that causes.

Claims

1. safety-type ultraviolet drier, comprise board (1), be contained in inner cover (2) in the board (1), be installed in discharge pipe (3) on the inner cover (2), be contained in air exhauster (4), the blast switch (5) of discharge pipe (3) mouthful, it is characterized in that: described blast switch (5) is located on the inner cover (2) in the board (1); The port of the negative pressure pipe (51) that blast switch (5) is drawn is arranged on discharge pipe (3) inwall; Signal output contact (52) on the blast switch (5) is connected by the gauge tap of lead with board (1).
