Description

Technical Field

[0001] The utility model belongs to the technical field of glue coating, and in particular relates to a more efficient pressure plate pump fluid supply device. Background Art

[0002] In the field of glue coating, glue fluid is usually prepared in advance and stored in a glue barrel, and then a fluid supply device is used to extract the glue fluid in the glue barrel and inject glue for use.

[0003] After searching and combining it with actual glue coating processing experience, we found that the glue coating industry currently generally uses a pressure plate pump for glue supply. However, this method has a significant disadvantage: the glue at the bottom of the glue barrel is difficult to extract, resulting in a large amount of glue residue. Insufficient glue supply also results in glue waste. In addition, a large amount of impurities in the glue fluid are extracted and transported along with the glue, resulting in quality issues. Therefore, to address the above-mentioned shortcomings known in the art, our company has improved the existing pressure plate pump fluid supply device and provided a more efficient pressure plate pump fluid supply device. Utility Model Content

[0009] As a preferred embodiment, the vertical center lines of the exhaust pipe and the exhaust hole coincide with each other, the length of the exhaust hole is equal to the thickness of the pressure plate body, and the bottom end of the exhaust pipe is connected to the top end of the exhaust hole.

[0010] As a preferred embodiment, a glue inlet hole is opened at the center of the bottom end of the pressure plate body, the retaining ring is located directly below the glue inlet hole, and the diameter of the retaining ring is greater than the diameter of the glue inlet hole.

[0011] As a preferred embodiment, a plurality of filter holes are evenly opened inside the retaining ring. Compared with the prior art, the beneficial effects of the present invention are:

[0012] In the solution of the present utility model:

[0013] The pressure plate body is moved down into the glue barrel, and two rubber sealing rings are used to seal the pressure plate body and the inner wall of the glue barrel, thereby preventing glue leakage when the pressure plate body presses down the glue in the glue barrel to supply glue.

[0022] 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:

[0023] like Figure 1-4 As shown, the utility model is a more efficient pressure plate pump fluid supply device, which includes a pressure plate body 1 and a pressure plate pump body 5. The outer wall of the pressure plate body 1 is provided with two retention grooves 2 in the vertical direction, and a sealing ring 3 is bonded in the retention groove 2. An exhaust component 4 is fixedly provided on the upper left side of the pressure plate body 1, and a pressure plate pump body 5 is fixedly installed on the middle part of the upper end of the pressure plate body 1. A glue outlet 6 is provided in front of the top of the pressure plate pump body 5. A retaining ring 7 is fixedly connected to the center of the bottom end of the pressure plate body 1, and an air extraction hole 9 is provided inside the left end of the pressure plate body 1.

[0024] On the basis of the above structure, the retaining groove 2 and the sealing ring 3 are arranged in a one-to-one correspondence, and the sealing ring 3 is made of elastic rubber.

[0025] In this embodiment, a sealing ring 3 made of elastic rubber material is used to facilitate sealing between the pressure plate body 1 and the inner wall of the glue barrel, thereby preventing glue leakage when the pressure plate body 1 presses the glue downward in the glue barrel to supply glue.

[0026] Based on the above structure, the exhaust assembly 4 includes an exhaust pipe 41, an exhaust hole 42 and a valve 43. The exhaust pipe 41 is fixedly connected to the upper left of the pressure plate body 1. The exhaust hole 42 is opened at the top of the exhaust pipe 41, and a valve 43 is installed in the middle of the exhaust pipe 41.

[0027] Based on the above structure, the vertical center lines of the exhaust pipe 41 and the exhaust hole 9 coincide with each other, the length of the exhaust hole 9 is equal to the thickness of the pressure plate body 1, and the bottom end of the exhaust pipe 41 is connected to the top end of the exhaust hole 9.

[0028] In this embodiment, the exhaust assembly 4 and the exhaust hole 9 are used to easily draw a vacuum into the glue barrel, thereby generating an air pressure difference between the inside and outside of the glue barrel, and utilizing the air pressure difference to facilitate the rapid extraction and transportation of the residual glue fluid in the glue barrel through the filter hole 8 inside the retaining ring 7, so as to facilitate reducing the residual glue fluid in the glue barrel and achieving the purpose of more complete glue discharge.

[0029] On the basis of the above structure, a glue inlet hole is opened at the center of the bottom end of the pressure plate body 1, and the retaining ring 7 is located directly below the glue inlet hole, and the diameter of the retaining ring 7 is greater than the diameter of the glue inlet hole.

[0030] On the basis of the above structure, a plurality of filter holes 8 are evenly formed inside the retaining ring 7 .

[0031] In this embodiment, the plurality of filter holes 8 provided inside the retaining ring 7 are used to filter out impurities contained in the glue fluid during the glue supply process, thereby improving the glue supply quality.

[0032] The working principle of this utility model is as follows:

[0033] When in use, firstly, the pressure plate body 1 is lowered into the glue barrel and the bottom end surface of the pressure plate body 1 is in contact with the glue. At this time, two rubber sealing rings 3 are used to facilitate the sealing between the pressure plate body 1 and the inner wall of the glue barrel, thereby preventing glue leakage between the pressure plate body 1 and the glue barrel when the pressure plate body 1 is controlled to press the glue downward for glue supply. Moreover, when the pressure plate pump body 5 is turned on for glue supply, the plurality of filter holes 8 evenly arranged inside the retaining ring 7 can also facilitate filtering out impurities contained in the glue fluid, thereby improving the glue supply quality.

[0034] Before extracting and transporting the glue, the existing vacuum pump can be used to evacuate the glue barrel through the exhaust pipe 41 and the exhaust hole 9. When the pressure plate body 1 is pressed to the bottom of the glue barrel, the vacuum state in the glue barrel is utilized to generate an air pressure difference inside and outside the glue barrel. The air pressure difference can be utilized to quickly extract and transport the residual glue fluid in the glue barrel through the filter hole 8 inside the retaining ring 7, thereby achieving the purpose of reducing the residual glue fluid in the glue barrel and more fully draining the glue. The extracted glue fluid can be transported through the glue outlet 6 and the external glue delivery pipeline.

[0035] 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.
