Description

Technical Field

[0001] The utility model belongs to the technical field of glue coating, in particular to a device which can convert high-pressure fluid into low-pressure fluid for output. Background Art

[0002] Gluing is a process of evenly applying glue to the surface of an object. There are four main methods of gluing: scraping, roller coating, dipping and spraying. In the gluing industry, long-distance glue supply will cause the fluid pressure to be too high when it reaches the working pump body.

[0003] However, high-pressure fluids can easily interfere with and affect the normal operation of the pump body. Therefore, it is usually necessary to reduce the pressure of the high-pressure fluid. However, after searching and researching, it was found that in the field of glue coating, there is a lack of a fast and efficient glue fluid pressure reduction device, which makes it difficult to achieve rapid pressure reduction of the glue fluid, affecting the glue coating process. Therefore, it is urgent to improve the existing defects and shortcomings and provide a device that can convert high-pressure fluid into low-pressure fluid output. Utility Model Content

[0004] The purpose of this utility model is to address the deficiencies in the prior art and to provide a device with a reasonable design, simple structure, and the ability to quickly convert high-pressure fluid into low-pressure fluid output, thereby solving the problems in the prior art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A device that can convert high-pressure fluid into low-pressure fluid output, comprising an outer shell, an air inlet being provided at a middle position at the top end of the outer shell, a cylinder being fixedly mounted on the inner side of the top end of the outer shell, a ejector pin being fixedly connected to the output end of the cylinder, a sealing assembly being provided on a sliding sleeve on the outer side of the bottom end of the ejector pin, the sealing assembly being fixedly located on the inner side of the upper end of the outer shell, a glue inlet being provided on the right side wall of the outer shell, a glue outlet being provided on the left side wall of the outer shell, the glue outlet and the glue inlet being symmetrical about the outer shell, and a closing mechanism being fixedly mounted on the middle position at the bottom end of the outer shell.

[0007] As a preferred embodiment, the bottom end of the ejector pin passes through the sealing assembly, which includes a rubber gasket and a metal gasket, and the rubber gasket is located between two layers of the metal gaskets.

[0008] As a preferred embodiment, the outer shell, ejector pin and sealing mechanism are all made of 304 stainless steel.

[0009] As a preferred embodiment, the sealing mechanism includes a seal, a glue inlet cavity, a through hole, a spring, a support and a tungsten steel ball. The seal is fixedly installed in the middle position of the bottom end of the outer shell. A glue inlet cavity is opened inside the top end of the seal, and a through hole is opened on the inner wall of the bottom end of the glue inlet cavity. A spring is fixedly installed on the inner bottom of the glue inlet cavity, the top end of the spring is fixedly connected to the support, and the top of the support is fixedly connected to the tungsten steel ball.

[0010] As a preferred embodiment, the diameter of the top opening of the glue inlet cavity is smaller than the diameter length of the tungsten steel ball, the tungsten steel ball is located directly below the ejector pin, and the tungsten steel ball contacts and seals the top opening of the glue inlet cavity.

[0011] As a preferred embodiment, the glue inlet is connected to the glue inlet cavity, and the glue inlet cavity is connected to the glue outlet via a through hole.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the solution of the present utility model:

[0014] Applying pressure to the cylinder from the air inlet controls the downward movement of the ejector pin, which in turn applies pressure to the tungsten steel ball, pushing the tungsten steel ball and the support member downward and gradually compressing the spring. At this time, the glue fluid entering from the glue inlet can flow along the opened glue inlet cavity and through the through hole toward the glue outlet. In this process, high-pressure fluid can be converted into low-pressure fluid output. The fluid pressure at the glue outlet depends on the amount of compression of the spring by the ejector pin pushing the tungsten steel ball and the support member and the size of the opened glue inlet cavity, that is, the air pressure at the air inlet. Through this device, high-pressure fluid can be quickly converted into low-pressure fluid output, thus preventing the high-pressure fluid from interfering with and affecting the normal operation of the pump body.

[0015] The sealing assembly, consisting of a rubber gasket and two layers of metal gaskets, can ensure that the fluid will not penetrate into other parts of the device and cause leakage. The main body of the device is made of 304 stainless steel, which has high strength and good corrosion resistance, and can effectively extend the service life of the device.

[0023] The embodiments described below are only a portion of the embodiments of the present invention and do not represent all embodiments consistent with the present invention. The exemplary embodiments are described below in conjunction with the accompanying drawings:

[0024] like Figure 1-4 As shown, the utility model can convert high-pressure fluid into a device for low-pressure fluid output, which includes an outer shell 1, an air inlet 2 is opened at the middle position of the top of the outer shell 1, a cylinder 3 is fixedly installed on the inner side of the top of the outer shell 1, and the output end of the cylinder 3 is fixedly connected to a ejector pin 4, and a sealing assembly is provided on the outer sliding sleeve of the bottom end of the ejector pin 4, and the sealing assembly is fixedly located on the inner side of the upper end of the outer shell 1, a glue inlet 7 is opened on the right side wall of the outer shell 1, and a glue outlet 8 is opened on the left side wall of the outer shell 1, and the glue outlet 8 and the glue inlet 7 are symmetrical about the outer shell 1, and a closing mechanism 9 is fixedly installed at the middle position of the bottom end of the outer shell 1.

[0025] On the basis of the above structure, the bottom end of the ejector pin 4 passes through the sealing assembly. The sealing assembly includes a rubber gasket 5 and a metal gasket 6 . The rubber gasket 5 is located between the two layers of metal gaskets 6 .

[0026] In this embodiment, the provision of the sealing component can prevent the glue fluid from penetrating into other parts of the device, thereby preventing glue leakage.

[0027] On the basis of the above structure, the outer shell 1, the ejector pin 4 and the closing mechanism 9 are all made of 304 stainless steel.

[0028] In this embodiment, the main components of the device are all made of 304 stainless steel, which has high strength and good corrosion resistance, and can effectively extend the service life of the device.

[0029] On the basis of the above structure, the closing mechanism 9 includes a sealing member 91, a glue inlet cavity 92, a through hole 93, a spring 94, a support member 95 and a tungsten steel ball 96. The sealing member 91 is fixedly installed at the middle position of the bottom end of the outer shell 1. The top end of the sealing member 91 is provided with a glue inlet cavity 92. The bottom inner wall of the glue inlet cavity 92 is provided with a through hole 93. The inner bottom of the glue inlet cavity 92 is fixedly installed with a spring 94. The top end of the spring 94 is fixedly connected to the support member 95. The top of the support member 95 is fixedly connected to the tungsten steel ball 96.

[0030] Based on the above structure, the diameter of the top opening of the glue inlet cavity 92 is smaller than the diameter length of the tungsten steel ball 96. The tungsten steel ball 96 is located directly below the ejector pin 4. The tungsten steel ball 96 contacts and seals the top opening of the glue inlet cavity 92.

[0031] On the basis of the above structure, the glue inlet 7 is connected to the glue inlet cavity 92 , and the glue inlet cavity 92 is connected to the glue outlet 8 via a through hole 93 .

[0032] In this embodiment, the tungsten steel ball 96 and the support member 95 are pushed downward by the ejector pin 4, and the spring 94 is gradually compressed. At this time, the glue fluid entering from the glue inlet 7 can flow along the opened glue inlet cavity 92 and through the through hole 93 toward the glue outlet 8. In this process, the high-pressure fluid can be quickly converted into a low-pressure fluid output, which can avoid the high-pressure fluid from interfering with and affecting the normal operation of the pump body.

[0033] The working principle of this utility model is as follows:

[0034] When in use, first, one end of the existing air pipe is fixedly connected to the air inlet 2, and the glue fluid delivery pipe is fixedly connected to the glue inlet 7, and the glue fluid discharge pipe is fixedly connected to the glue outlet 8. During the glue fluid output process, pressure can be applied to the cylinder 3 from the air inlet 2 to control the ejector pin 4 to move downward and apply pressure to the tungsten steel ball 96, which can push the tungsten steel ball 96 and the support member 95 downward and gradually compress the spring 94. At this time, the glue fluid entering from the glue inlet 7 can flow along the opened glue inlet cavity 92 and through the through hole 93 toward the glue outlet 8. In this process, the high-pressure fluid can be converted into a low-pressure fluid output;

[0035] The fluid pressure at the glue outlet 8 depends on the amount of compression of the spring 94 by the ejector pin 4 pushing the tungsten steel ball 96 and the support 95, and the size of the top opening of the glue inlet chamber 92, that is, the air pressure at the air inlet 2. Through the conversion of this device, high-pressure fluid can be quickly converted into low-pressure fluid output. After experiments, it can convert the fluid with a maximum pressure of 21MPa at the glue inlet 7 into a fluid with a maximum pressure of 1MPa at the glue outlet 8, thereby preventing the high-pressure fluid from interfering with and affecting the normal operation of the pump body.

[0036] In this device, a sealing assembly consisting of a rubber gasket 5 and two layers of metal gaskets 6 is used to ensure that the fluid does not penetrate into other parts of the device and cause leakage. In addition, the main components of the device are made of 304 stainless steel, which has the characteristics of high strength and good corrosion resistance, and can effectively extend the service life of the device.

[0037] The above are only preferred specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any equivalent changes, modifications, substitutions and variations made by technicians in this technical field based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of existing technologies should be within the scope of protection determined by the claims.
