Description

Technical Field

[0001] The utility model relates to the field of hollow glass production, in particular to a TPSS glue supply channel exhaust mechanism. Background Art

[0002] Insulating glass is a new type of building material that has good heat insulation, sound insulation, is beautiful and practical, and can reduce the weight of buildings. The common insulating glass on the market is mostly formed by adding metal spacers between two or more pieces of glass to support the formation of a hollow layer, and two layers of gluing are used to ensure the sealing of the hollow layer. Although the metal spacers give the insulating glass a reasonable hollow layer thickness and service life, the metal spacers conduct heat too quickly, and when the temperature difference between indoors and outdoors convects, metal heat bridges will be formed, which significantly reduces the thermal insulation of the glass. Therefore, with the development of science and technology, based on factors such as energy consumption, TPSS thermoplastic warm edge spacers came into being.

[0003] In the production of TPSS thermoplastic warm edge spacer glue, higher requirements are placed on the continuity of the glue discharge of thermoplastic warm edge spacer glue. During each initial glue application, in addition to the air in the glue barrel that needs to be discharged, there will also be some air in the glue supply channel. Failure to discharge will cause a disconnection between the last residual glue and the new glue, and the gear pump will be easily damaged if it runs idle without glue. At present, exhaust and blocking are mainly achieved by opening an exhaust hole at the end of the glue supply channel and a matching cover. Such a setting is not only troublesome to disassemble and assemble, but also not conducive to the realization of automated glue production. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art, the utility model provides a TPSS glue supply channel exhaust mechanism, which can automatically open the exhaust port for exhaust when exhaust is needed and can automatically seal after exhaust. The entire exhaust operation is fast and convenient, laying a foundation for realizing fully automated gluing production of insulating glass.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] A TPSS glue supply channel exhaust mechanism, comprising a fixed block fixed at an exhaust port of the glue supply channel, an exhaust channel for connecting the glue supply channel with the outside world is provided in the fixed block, a valve column is installed in the exhaust channel, and the valve column can be driven to rotate by a driving member so that it has a first state of cutting off the glue supply channel from the outside world and a second state of connecting;

[0007] The driving member includes a telescopic cylinder, a lever arm and a mounting seat. One end of the lever arm is fixed relatively to the valve column, and the other end is hinged to the output end of the telescopic cylinder through a first hinge shaft. The top of the telescopic cylinder is hinged to the mounting seat through a second hinge shaft. The first hinge shaft and the second hinge shaft are arranged in the same direction so that the valve column can be driven to change between the first state and the second state by the telescopic cylinder extending and retracting.

[0008] Preferably, a sealing ring is provided between the fixing block and the exhaust port.

[0009] Preferably, the piston rod end of the telescopic cylinder is connected to the first hinge shaft through a fisheye joint. Such an arrangement can reduce the difficulty of matching between the various components and facilitate smooth and flexible realization of valve column state changes.

[0010] Preferably, one end of the valve column close to the driving member is configured as a prism section, and one end of the lever arm is provided with a lever hole matched with the prism section, so that the valve column can be easily replaced when a problem occurs with the valve column.

[0011] Preferably, the telescopic cylinder can be a pneumatic cylinder.

[0012] The utility model adopts the above technical solution, and has the advantages that: the TPSS glue supply channel exhaust mechanism realizes the on-off coordination between the glue supply channel and the outside world through the fixed block, the valve core and the driving part, and can automatically connect the outside world and the exhaust port for exhaust when exhaust is needed, and can automatically seal after exhaust is completed. The entire exhaust operation is fast and convenient, which lays the foundation for the subsequent realization of fully automated glue production of hollow glass. Among them, the valve column is set as a prismatic section and a lever arm, which will make it easier to replace the valve core when there is a problem with the valve column.

DETAILED DESCRIPTION

[0017] In order to clearly illustrate the technical features of the present solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings. In the following description, many specific details are described to facilitate a full understanding of the present application. However, the present application can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0018] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0019] like Figure 1-3 As shown, in this embodiment, the TPSS glue supply channel exhaust mechanism includes a fixed block 3 fixed at the exhaust port 2 of the glue supply channel 1, and the fixed block 3 is provided with an exhaust channel 301 connecting the glue supply channel 1 with the outside world. A valve column 4 is installed in the exhaust channel 301, and the valve column 4 can be driven to rotate by a driving member 5 so that it has a first state of cutting off the glue supply channel 1 from the outside world and a second state of connecting; the driving member 5 includes a telescopic cylinder 501, a lever arm 502 and a mounting seat 503, one end of the lever arm 502 is relatively fixed to the valve column 4, and the other end is hinged to the output end of the telescopic cylinder 501 through a first hinge shaft 504, and the top of the telescopic cylinder 501 is hinged to the mounting seat 503 through a second hinge shaft 505, and the first hinge shaft 504 and the second hinge shaft 505 are arranged in the same direction, so that the telescopic cylinder 501 can be extended to drive the valve column 4 to change between the first state and the second state. Among them, the telescopic cylinder can be, but is not limited to, a cylinder, an electric cylinder, and the like.

[0020] Working principle: When the glue supply channel 1 needs to be exhausted, the gear pump of the glue supply mechanism first rotates at a low speed, and at the same time, the telescopic cylinder 501 retracts to drive the lever arm 502 to rotate with the valve column 4 as the axis. Since the lever arm 502 and the valve column 4 are relatively fixed, the lever arm 502 will drive the valve column 4 to rotate. After rotating ninety degrees, the valve hole of the valve column 4 will be connected to the outside world and the glue supply channel for exhaust. Specifically, as the glue supply pressure plate presses down on the glue supply, the gas in the glue supply channel is gradually exhausted. After the exhaust is completed, when the glue is discharged through the exhaust channel, the exhaust is completed. At this time, the telescopic cylinder 501 extends to drive the lever arm 502 to rotate in the opposite direction. The lever arm 502 synchronously drives the valve column 4 to rotate ninety degrees in the opposite direction to achieve the blocking of the exhaust channel. After that, the gear pump can rotate at a high speed to supply glue. The exhaust mechanism of the present application can quickly complete the exhaust operation, save trouble and labor, and is conducive to the realization of fully automated glue production of insulating glass.

[0021] In one of the specific embodiments, a sealing ring 6 is further provided between the fixing block 3 and the exhaust port 2 to achieve better sealing during the glue supply process, which is beneficial to the stable pressure glue supply.

[0022] In one specific embodiment, the piston rod end of the telescopic cylinder 501 can be connected to the first hinge shaft 504 through a fisheye joint 506. Such a configuration can reduce the difficulty of matching between the various components and facilitate the smooth and flexible transformation of the two states of the valve column.

[0023] In one of the specific embodiments, when the valve column has problems such as poor sealing and other problems and needs to be replaced, in order to facilitate the replacement of the valve column, the following settings can be made: the end of the valve column 4 close to the driving member 5 is set as a prismatic segment, and one end of the lever arm 502 is provided with a lever hole that cooperates with the prismatic segment, so that the valve column 4 can be driven to rotate through the lever arm 502.

[0024] The above-mentioned specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.

[0025] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
