Abstract

The utility model provides a safety device of a screen plate printer, which has the advantage of better safety. The utility model is aimed at eliminating the safety problem of workers when the workers clean the stains of the screen plates of the commonly used screen printers. A set of an operating press cylinder is matched in a screen plate lifting mechanism of the screen plate printer, and the operating press cylinder is matched with a preset safety through hole penetrating the screen plate lifting mechanism. After the screen plate lifting mechanism is raised, an operating rod of the operating press cylinder can penetrate in the safety through hole to ensure that the lifting mechanism can not fall accidentally. The utility model can display better safety.

Description

The safety device of screen printer

The utility model is the safety device about a kind of screen printer, particularly, is meant a kind ofly by members such as action cylinder pressure, safe through holes, and common composition can make the design of the better security of screen printer performance.

Because making level, modern printing industry day by day improves, the use of screen printer is very general especially, and in the printing apparatus indispensable one especially of the half tone of screen printer, but, owing to use after a period of time this half tone just can be stopped up or stained by printing ink, just need the staff to enter to scrape under tool rest, flood bar seat, print arm and the half tone to clear up, there is when damage also to need the staff to enter operation under the half tone in mechanism in addition, so the convenience of cleaning, maintenance work and security just become the characteristic of using manufacturer to pay attention to the most; Therefore, how to develop the safety device of the screen printer of a kind of prune job convenience and the better security of tool, become developer and manufacturer already and want most several problems of overcoming, and the problem that is presented in the foregoing also is the motivation that the inventor researches and develops this case.

Traditional screen printer sees also shown in Figure 1ly, is to adopt an actuating strut 10 turns, drives toothed chain 11 again, and through behind some induction sprockets 12, makes bracing frame 13 by upwards pulling of toothed chain 11, and upwards rise from board 14 working faces; The elevating mechanism of the screen printer that this kind is commonly used is being sold on the market, is being used for a long time, but this kind design through after the long-term use, still finding has weak point, makes its effect clear, tracing it to its cause is to be:

Owing to use after a period of time this half tone 15 just can be stopped up or stained by printing ink, scrape tool rest 16 and need the staff to enter, flood bar seat 17, cleaning under print arm 18 and the half tone 15, and above-mentioned parts all are to support with bracing frame 13, also be to support with toothed chain 11, and upwards rise from board 14 working faces by bracing frame 13, when so the staff clears up the maintenance work of half tone 15 or each mechanism, parts weight above the staff is very surprising, and the support force of toothed chain 11 not only has its limit, whether and it is firm to have assembling, the problem of material lifetime length, so the staff can have great security doubt when advancing cleaning work, the mental handicape when causing cleaning and the danger of mechanism itself.

Primary and foremost purpose of the present utility model is to provide the safety device of the better screen printer of a kind of security; The utility model sets the set cylinder pressure in the half tone elevating mechanism of screen printer, and default safe through hole to wear in the action cylinder pressure actuating strut cooperation half tone elevating mechanism, after the half tone elevating mechanism is raise, action cylinder pressure actuating strut can penetrate in the safe through hole, to guarantee that elevating mechanism can accident not fall, make the better security of screen printer performance.

The purpose of this utility model is achieved in that a kind of safety device of screen printer, it is characterized in that comprising: a board is a pedestal, is provided with some action grooves in all sides, and is provided with two relative through holes in the predeterminated position system of action groove; Some bracing frames are a bridge body, and are to slide to be located in the action groove of board, and the supporting framing front end group is provided with a chain that is connected to default power; Some action cylinder pressures are action cylinder pressures, and are that group is located in the board, have an actuating strut in action in the cylinder pressure, and actuating strut is corresponding to two relative through holes in the action groove.Wherein the action of this action cylinder pressure, bracing frame can be to utilize the operation of automatic control circuit system.

In sum, the utility model is to set the set cylinder pressure in the half tone elevating mechanism of screen printer, and default safe through hole to wear in the action cylinder pressure actuating strut cooperation half tone elevating mechanism, after the half tone elevating mechanism is raise, action cylinder pressure actuating strut can penetrate in the safe through hole, to guarantee that elevating mechanism can accident not fall, make the better security of screen printer performance.

30. action cylinder pressure 31. actuating struts

Relevant the utility model is the technology of reaching above-mentioned purpose, being adopted, means and other effects, but enumerate a preferable embodiment now and cooperate graphic detailed description as after, believe the purpose of this utility model, feature and other advantages, when can by one deeply and concrete understanding; See also shown in Figure 2ly again, can understand and show that the utility model is made of jointly members such as board 20, bracing frame 21 and action cylinder pressures 30, wherein:

This board 20 is a pedestal, is provided with some action grooves 22 in all sides, and is provided with two relative through holes 23 in the predeterminated position system of action groove 22;

This bracing frame 21 is a bridge body, and is to slide to be located in the action groove 22 of board 20, and bracing frame 21 front group are provided with a chain 24 that is connected to default power;

This action cylinder pressure 30 is one can utilize the action cylinder pressure 30 of control circuit operation, and is that group is located in the board 20, has an actuating strut 31 in action cylinder pressure 30, and actuating strut 31 is corresponding to two relative through holes 23 in the action groove 22; The above is the correlation position of each related elements of the utility model and the general introduction of structure thereof.

In order to clearly demonstrate manner of execution of the present utility model and effect, please cooperate again consult shown in Figure 3, the utility model is when normal running, since board 20 need with bracing frame 21 on each unit interoperation, so bracing frame 21 need wear action groove 22 bottoms to board 20, make the position can be by being attached to operation on the board 20 at each unit on the bracing frame 21, this action cylinder pressure 30 then remains in the board 20, move actuating strut 31 in the cylinder pressure 30 also keep in the state of receipts.

Then please consult shown in Figure 4 again, after using a period of time, the user need be to being stopped up by printing ink on the bracing frame 21 or stained mechanism when clearing up and keeping in repair, the user can utilize automatic control system to open the default power of chain 24, make chain 24 begin action, and the guiding by chain cable fairlead 25 drives bracing frame 21, make bracing frame 21 rising of in the action groove 22 of board 20, sliding, and after rising to predeterminated position, the power of automatic control system meeting breakdown action cylinder pressure 30, make the actuating strut 31 of action cylinder pressure 30 push away forward and stretch, and actuating strut 31 can corresponding stretch in two comparatively speaking the through holes 23 of action groove 22; Utilize above-mentioned action, the utility model can be in bracing frame 21 displacements aloft the time, be stuck in actuating strut 31 envelopes in the action groove 22 of board 20, make bracing frame 21 when accident falls, still can be by actuating strut 31 blockings, so be positioned at the work that the operating personnel of 20 of mechanism on the bracing frame 21 and boards can clear up and keep in repair under the most stable mood, do not have the security doubt again, the danger of mental handicape when causing the Qing Dynasty and mechanism itself.
