Description

A kind of wool-weaving machine that has reducing valve

Technical field

The utility model relates to a kind of wool-weaving machine, particularly relates to a kind of wool-weaving machine that has reducing valve.

Background technology

Wool-weaving machine is one of the key equipment that need use in the production technique of silicon solar cell; The general PLC of employing controls, and touch screen operation can be realized manual and automatic making herbs into wool cleaning whole process; Adopt wall-hanging mechanical manipulator mode to move in addition, can regulate the process time voluntarily.As shown in Figure 1; Be the substruction of present most of wool-weaving machines; Eight groove positions, a last material level 11 and a following material level 12 are arranged; One winding displacement paths 14 is arranged in the place of switching push button 13, and circuit wherein links to each other with circuit in the switch cabinet 15, and the inner air pressure of the air pressure in the line channel 14 and wool-weaving machine are equal.The defective that existing wool-weaving machine exists is: when the temperature in the external workshop is higher than the wool-weaving machine temperature inside; The wool-weaving machine the inside can produce a large amount of water vapour; Include some chemical ingredientss in these steams, water vapour will get in the PLC circuit path or advance in drainage switch and the emergency stop switch button, can cause circuit the situation of short circuit to occur or corrode circuit causing opening circuit like this; Therefore each maintenance platoon line inspection road problem all will spend the regular hour; So not only influence normal daily production, and can reduce the life-span of equipment, increase the additional maintenance cost of equipment.

The utility model content

The technical problem that the utility model will solve provides a kind of wool-weaving machine that has reducing valve, can avoid water vapour to get into the PLC cable tubing, prolongs equipment life, reduces production costs.

For solving the problems of the technologies described above, the technical scheme of the utility model is:

A kind of wool-weaving machine that has reducing valve, said wool-weaving machine comprise PLC cable tubing, nitrogen pipeline, bubbling unit, and said PLC cable tubing is used for control, be full of nitrogen in the said nitrogen pipeline and be used for to bubbling unit input nitrogen,

Said wool-weaving machine also comprises reducing valve; Said reducing valve comprises inlet mouth, first air outlet, second air outlet; Said inlet mouth is connected in said nitrogen pipeline, and said first air outlet is connected in said bubbling unit, and said second air outlet is connected in said PLC cable tubing; Said nitrogen pipeline is imported nitrogen through said first air outlet to the bubbling unit, and imports nitrogen through said second air outlet to the PLC cable tubing.

Preferably, the said reducing valve of the utility model is provided with the setter that is used to regulate air pressure.

Therefore compared with prior art, the utility model has following beneficial effect:

Reducing valve can be shunted a part of nitrogen with the nitrogen in the original nitrogen pipeline and come out, and in this part nitrogen input PLC cable tubing, makes the air pressure of the inner air pressure of PLC cable tubing greater than wool-weaving machine inside; The water vapour that produces in the wool-weaving machine when producing so can not enter in the PLC cable tubing; Also can not get into switch, the generation of avoided short circuit fully, opening circuit has guaranteed normally carrying out of production; Also practice thrift the ME cost, reduced production cost.

Description of drawings

Accompanying drawing described herein is used to provide the further understanding to the utility model, constitutes the application's a part, does not constitute the improper qualification to the utility model, in the accompanying drawings:

Fig. 1 is the structural representation of existing wool-weaving machine;

Fig. 2 is the structural representation of the utility model embodiment;

Fig. 3 is the structural representation of reducing valve among the utility model embodiment.

Embodiment

To combine accompanying drawing and specific embodiment to specify the utility model below, be used for explaining the utility model in the illustrative examples and the explanation of this utility model, but not as the qualification to the utility model.

Be the described a kind of embodiment that has the wool-weaving machine of reducing valve of the utility model as shown in Figures 2 and 3; Wool-weaving machine comprises PLC cable tubing 2, nitrogen pipeline 3, bubbling unit; PLC cable tubing 2 is used for control, is full of nitrogen in the nitrogen pipeline 3 and is used for to bubbling unit input nitrogen, and present embodiment also comprises reducing valve 4; Reducing valve 4 comprises inlet mouth 41, first air outlet 42, second air outlet 43; Inlet mouth 41 is connected in nitrogen pipeline 3, the first air outlets 42 and is connected in the bubbling unit, and second air outlet 43 is connected in PLC cable tubing 2; Nitrogen pipeline 3 is imported nitrogen through first air outlet 42 to the bubbling unit, and imports nitrogen through second air outlet to the PLC cable tubing.

Preferably, in the present embodiment, reducing valve 4 is provided with the setter 44 that is used to regulate air pressure, can regulate the air pressure size of nitrogen during operation as required, according to actual measured results, need be that 0.4Pa gets final product with the nitrogen pressure size adjustment through setter 44 only.

More than technical scheme that the utility model embodiment is provided carried out detailed introduction; Used concrete example among this paper principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
