AI Technical Summary
The sealing mechanism of the drum on the existing glass hollow equipment cannot fully match the inner diameter of the drum, resulting in poor sealing effect and a problem of glue leakage.
A sealing mechanism including a sealing disc, a limiting rod and an inflatable sealing ring is designed. The outer diameter of the piston structure is adjusted through the air nozzle of the inflatable sealing ring, so that it is closely combined with the inner side wall of the glue barrel to enhance the sealing effect.
By fine-tuning the outer diameter of the piston structure, the tight combination of the inner side wall of the glue barrel and the sealing ring is achieved, which significantly improves the sealing effect and avoids the problem of glue leakage.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of glass deep processing equipment and relates to a sealing mechanism of a glue barrel on a glass hollow equipment. Background Art
[0002] Insulating glass is a glass deep-processing product that consists of two or more pieces of glass separated by a spacer frame and sealed with sealant to form a dry gas space between the glass layers. The edges of the insulating glass are completely sealed with sealant, which is generally packaged in barrels and can be used after unpacking. During the use of the sealant, it is still necessary to keep it sealed to prevent the outside air from mixing into the sealant.
[0003] However, among the structural adhesive products currently used in glass hollow processing, even if the sealants of the same brand and specification are used, there is still an error of 1 to 2 mm in the barrel diameter. As a result, the sealing mechanism of the glue barrel on the existing hollow equipment is always unable to completely match the inner diameter of the glue barrel, and thus cannot achieve the expected sealing effect, causing glue leakage in the glue barrel. Utility Model Content
[0004] The purpose of the utility model is to address the above-mentioned problems existing in the prior art and to provide a sealing mechanism for a glue barrel on a glass hollow equipment, aiming to make its outer diameter finely adjustable, thereby compensating for the error in the inner diameter of the glue barrel and improving the sealing effect of the glue barrel.
[0005] The purpose of the utility model can be achieved through the following technical solutions: a sealing mechanism for a glue barrel on a glass hollow equipment, characterized in that the mechanism includes a sealing disk, a limiting rod is vertically fixed at the center position of the top of the sealing disk, a glue outlet channel is provided in the limiting rod, and the bottom surface of the sealing disk is connected to the glue outlet channel; an installation groove is provided on the outer peripheral surface of the sealing disk, an inflatable sealing ring is provided in the installation groove, and an air nozzle is provided on the inflatable sealing ring.
[0006] The utility model has the advantages:
[0007] In this sealing structure, the sealing disk and the inflatable sealing ring thereon together constitute a piston structure that can move up and down in the rubber barrel, and the inflatable sealing ring is provided with an air nozzle, so that we can shrink or expand the sealing ring by inflating and deflating air into the sealing ring, and then fine-tune the outer diameter of the piston structure, so that the outer periphery of the sealing ring is always tightly combined with the inner wall of the rubber barrel, thereby improving its sealing effect. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1 It is a three-dimensional structural schematic diagram of the sealing mechanism.
[0009] Figure 2 It is a schematic diagram of the application scenario of the sealing mechanism.
[0010] In the figure, 1. sealing disk; 2. limiting rod; 21. glue outlet channel; 3. inflatable sealing ring; 31. air nozzle; 4. glue barrel; 5. sealant. DETAILED DESCRIPTION
[0011] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0012] like Figure 1 and Figure 2 As shown, a sealing mechanism of a glue barrel on a glass hollow equipment includes a sealing disk 1, a limiting rod 2 is vertically fixed at the top center position of the sealing disk 1, a glue outlet channel 21 is provided in the limiting rod 2, and the bottom surface of the sealing disk 1 is connected to the glue outlet channel 21; a mounting groove is provided on the outer peripheral surface of the sealing disk 1, an inflatable sealing ring 3 is provided in the mounting groove, and an air nozzle 31 is provided on the inflatable sealing ring 3.
[0013] Working principle: In this sealing structure, the sealing disk 1 and the inflatable sealing ring 3 thereon together constitute a piston structure that can move up and down in the rubber barrel 4, and the inflatable sealing ring 3 has an air nozzle 31, so that we can shrink or expand the sealing ring by filling and releasing air into the sealing ring, and then fine-tune the outer diameter of the piston structure, so that the outer periphery of the sealing ring is always tightly combined with the inner wall of the rubber barrel 4, thereby improving its sealing effect. In this sealing structure, its limit rod 2 will be restricted by the hollow device, so that it can only move up and down without being skewed, so that it always maintains a sealed state to the space below it in the rubber barrel 4. When the sealant 5 in the barrel is continuously drawn out through the glue outlet channel 21, this mechanism will slowly move downward under the action of negative pressure, and then the sealant 5 in the rubber barrel 4 will be completely discharged.
[0014] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
