Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of paper processing, and particularly relates to an air supply device for paper processing. Background Art
[0002] Paper is generally divided into: letterpress printing paper, newsprint, offset printing paper, coated paper, book cover paper, dictionary paper, copy paper, board paper, etc.
[0003] Due to the light weight of paper, during the processing process, generally the positive pressure and negative pressure of gas are used to restrict the paper to change the position or posture of the paper. In order to achieve positive pressure and negative pressure, enterprises generally purchase air pumps for processing. Since a large number of air pumps are required and the unit price of air pumps is high, for enterprises, this is a relatively high expenditure. In addition, the existing air pumps have high noise, which will have an adverse impact on the health of employees. Since some enterprises are equipped with air compressors, there is an urgent need for an air supply device that uses an air compressor to provide positive and negative pressure gas for paper processing. Summary of the Utility Model
[0004] Aiming at the problems existing in the prior art, the utility model solves these problems with the following technical structure.
[0005] To achieve the above object, the utility model adopts the following technical scheme:
[0006] An air supply device for paper processing, comprising: a negative pressure component, a suction air pipe, a main pipeline, a first valve, and an air compressor air pipe. The suction air pipe is arranged at the suction port of the negative pressure component. One end of the air compressor air pipe is connected to the air compressor, and the other end is connected to the main pipeline. The suspended end of the main pipeline is connected to the air inlet of the negative pressure component. The first valve is arranged on the main pipeline.
[0007] Further,
[0008] The negative pressure component is a vacuum generator.
[0009] It further includes a pressure regulating valve, which is arranged on the main pipeline and is arranged on the side of the first valve close to the negative pressure component.
[0010] A pressure gauge is arranged on the pressure regulating valve.
[0011] It further includes a blowing air pipe, which is connected to the main pipeline and is arranged between the pressure regulating valve and the first valve.
[0012] A second valve is arranged on the blowing air pipe.
[0013] The second valve is a ball valve.
[0014] The first valve is an electromagnetic valve.
[0015] The suction air pipe is made of PVC or plastic.
[0016] The blowing air pipe is made of PVC or plastic.
[0017] Adopting the above structure of the present utility model can achieve the following beneficial effects:
[0018] The compressed air of the air compressor is introduced into the negative pressure assembly through the air compressor air pipe, so that the negative pressure assembly generates negative pressure, and the paper is adsorbed through the suction air pipe, thus replacing the air pump to limit the adsorption of the paper during the paper processing. For enterprises that already have an air compressor, the production cost is reduced, and the noise in the production workshop is reduced, making the working environment of employees better.

[0021] In order to enable those skilled in the art of the present technology to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0022] It should be noted that the terms "including" and "having" and any variations thereof in the description and claims of the present utility model and the above drawings are intended to cover non-exclusive inclusion. For example, a process, method, device, product or equipment that includes a series of steps or units does not necessarily have to be limited to those clearly listed steps or units, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or equipment.
[0023] The following is a further detailed description of the present application in conjunction with the attached Figure 1 drawings.
[0024] Refer to Figure 1A gas supply device for paper processing as shown includes: a negative pressure component 1, a suction air pipe 2, a main pipeline 3, a first valve 4, and an air compressor air pipe 5. The suction air pipe 2 is arranged at the suction port of the negative pressure component 1. One end of the air compressor air pipe 5 is connected to the air compressor, and the other end is connected to the main pipeline 3. The suspended end of the main pipeline 3 is connected to the air inlet of the negative pressure component 1. The first valve 4 is arranged on the main pipeline 3. In this way, the compressed air (positive pressure gas) of the air compressor is introduced into the negative pressure component 1 through the air compressor air pipe 5, so that the negative pressure component 1 generates negative pressure, and the paper is adsorbed through the suction air pipe 2, thus replacing the air pump to adsorb and limit the paper during the paper processing. For enterprises that already have an air compressor, the production cost is reduced, and the negative pressure component 1 can be a vacuum generator, such as the FESTO vacuum generator of FESTO, etc.
[0025] As Figure 1 shown, the device further includes a pressure regulating valve 6. The pressure regulating valve 6 is arranged on the main pipeline 3, and the pressure regulating valve 6 is arranged on the side of the first valve 4 close to the negative pressure component 1. In this way, the air pressure introduced into the negative pressure component 1 is regulated through the pressure regulating valve 6 to obtain compressed air with the required pressure value. In order to observe the pressure value in real time and accurately control it, a pressure gauge 9 is arranged on the pressure regulating valve 6, and the pressure value of the compressed air introduced into the negative pressure component 1 is displayed through the pressure gauge 9.
[0026] As Figure 1 shown, when the air pressure and gas volume of the compressed gas output by the air compressor are greater than the demand of the negative pressure component 1, some compressed gas needs to be discharged. Therefore, the device further includes a blowing air pipe 7. The blowing air pipe 7 is connected to the main pipeline 3, and the blowing air pipe 7 is arranged between the pressure regulating valve 6 and the first valve 4. In this way, part of the compressed gas from the air compressor is discharged through the blowing air pipe 7, and the discharged gas can also be used for processing, for example, blowing on the paper to change the position or posture of the paper; for cleaning, removing dust, etc. And a second valve 8 is arranged on the blowing air pipe 7 to control the on-off of the blowing air pipe 7. It is best to use a ball valve as the second valve 8. The ball valve has a simple structure, convenient operation, small fluid resistance, good sealing performance, and strong corrosion resistance.
[0027] Furthermore, it is optimal to use a solenoid valve as the first valve 4 because the solenoid valve can control the flow direction of liquid or gas, realize the positive and reverse flow of the flow rate, and can control the on-off of the air path channel or change the flow direction of the compressed air in the pneumatic circuit.
[0028] Furthermore, the suction air pipe 2 and the blowing air pipe 7 can be made of PVC or plastic. The PVC pipeline has the characteristics of being vacuum-resistant and high-pressure-resistant, while using plastic materials, such as steel skeleton plastic composite pipes, has the characteristics of pressure resistance, corrosion resistance, convenient installation, and strong negative pressure resistance. The specific material selection is adaptively selected according to the actual use requirements.
[0029] The working principle of the utility model is as follows: the compressed air (positive pressure gas) of the air compressor is passed into the negative pressure component 1 through the air compressor air pipe 5, so that the negative pressure component 1 generates negative pressure, and the paper is adsorbed through the suction pipe 2, thereby replacing the air pump, and the adsorption of the paper is restricted during the paper processing process. For enterprises that have air compressors themselves, the production cost is reduced, the noise in the production workshop is reduced, and the working environment of the employees is better.
[0030] The above are only preferred embodiments of the present application, and the present invention is not limited to the above embodiments. It is understood that other improvements and changes directly derived or associated by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included in the protection scope of the present invention.
