Description

Technical Field

[0001] The utility model relates to the field of hollow glass production, in particular to a TPSS glue barrel 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 gluing production of TPSS thermoplastic warm edge spacer strips, glue is applied to the edge of the glass through a glue supply mechanism. Each time the glue is applied for the first time, the glue barrel needs to be vented. The current exhaust method is mainly to open an exhaust port on the glue supply pressure plate, and install an exhaust valve at the exhaust port for manual exhaust. This exhaust has the following defects: First, residual glue in the exhaust valve may cause blockage, and heat transfer softening requires a certain amount of time, resulting in a long exhaust time; second, manual exhaust is required each time, which is troublesome. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art, the utility model provides a TPSS rubber barrel exhaust mechanism, which, on the one hand, is convenient for quickly exposing the exhaust port for exhaust, and automatic exhaust is more convenient; on the other hand, automatic blocking is not only convenient, but also has a more stable and reliable blocking effect.

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

[0006] A TPSS glue barrel exhaust mechanism comprises a mounting frame, a telescopic cylinder and an exhaust rod, wherein the mounting frame comprises a mounting base plate fixed at the exhaust port on the top of a glue supply pressure plate, an exhaust through hole connected to the exhaust port is provided in the middle of the mounting base plate, an annular groove is provided in the exhaust through hole, a sealing ring is installed in the annular groove, a bracket is fixedly connected to the mounting base plate to invertly install the telescopic cylinder above the mounting base plate, and the exhaust rod is connected to the output end of the telescopic cylinder so that the exhaust rod can be driven by the telescopic cylinder to have a first state of blocking the exhaust through hole and the exhaust port and a second state of exposing the exhaust through hole for exhaust.

[0007] Preferably, the lower end of the exhaust rod is a tapered end.

[0008] Preferably, the bracket includes a mounting top plate, and a fixing rod connected between the mounting top plate and the mounting bottom plate, the telescopic cylinder is inverted and fixed on the mounting top plate, and the output shaft of the telescopic cylinder is arranged to penetrate the mounting top plate.

[0009] Preferably, the telescopic cylinder is a pneumatic cylinder.

[0010] Preferably, the exhaust rod is fixedly connected to the output end of the telescopic cylinder through a connector, a flared opening is formed at the upper portion of the exhaust through hole, and a closing opening is arranged at the outer lower portion of the connector to match the flared opening.

[0011] The utility model adopts the above technical solution, which has the advantages that the TPSS glue barrel exhaust mechanism can automatically cooperate with the exhaust through hole and the exhaust port of the glue supply pressure plate through the structural settings of the mounting frame, the telescopic cylinder and the exhaust rod. On the one hand, it is convenient to quickly expose the exhaust port for the exhaust of the glue barrel, and on the other hand, the exhaust port can be reliably sealed to ensure the stability of the subsequent gluing process.

[0012] In summary, the use of the above-mentioned exhaust mechanism not only makes the entire exhaust operation fast and convenient, but also the sealing is stable and reliable, and it also lays the foundation for the subsequent realization of fully automated gluing production of insulating glass.

[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 barrel exhaust mechanism includes a mounting frame, a telescopic cylinder 1 and an exhaust rod 2. The mounting frame includes a mounting base plate 3 fixed at the exhaust port on the top of the glue supply platen. The middle of the mounting base plate 3 is provided with an exhaust through hole 4 connected to the exhaust port. An annular groove is provided in the exhaust through hole 4. A sealing ring 5 is installed in the annular groove. A bracket is fixed on the mounting base plate 3 to invert the telescopic cylinder 1 above the mounting base plate 3. The exhaust rod 2 is connected to the output end of the telescopic cylinder 1 so that the exhaust rod 2 can be driven by the telescopic cylinder 1 to have a first state of blocking the exhaust through hole 4 and the exhaust port and a second state of exposing the exhaust through hole 4 for exhaust. Among them, the telescopic cylinder can be, but is not limited to, a cylinder, a hydraulic cylinder and other structures.

[0020] Principle of use: When in use, install the exhaust mechanism corresponding to the exhaust port of the glue supply platen, and specifically fix the installation base plate 3 to the glue supply platen. When the glue barrel needs to be vented, the piston rod of the telescopic cylinder 1 retracts and takes the exhaust rod 2 out of the exhaust port and the exhaust through hole 4. As the glue supply platen moves down in the rubber barrel, the air in the rubber barrel will be gradually exhausted. Since the exhaust mechanism is fixed on the glue supply platen, it will move up and down with it; after exhausting, the piston rod of the telescopic cylinder 1 will take the exhaust rod 2 down, insert it into the exhaust through hole 4 and the exhaust port of the glue supply platen for sealing. Since a sealing ring is installed in the exhaust through hole 4 and the exhaust mechanism of this application is used for automatic sealing, the reliability of the sealing is guaranteed.

[0021] In one specific example, the lower end of the exhaust rod 2 is a tapered end, which facilitates the exhaust rod to be quickly and accurately inserted into the exhaust through hole and the exhaust port for sealing.

[0022] In one specific example, the bracket includes a mounting top plate 6 and a fixing rod 7 connected between the mounting top plate and the mounting bottom plate. The telescopic cylinder 1 is inverted and fixed on the mounting top plate. The output shaft of the telescopic cylinder 1 passes through the mounting top plate, which can limit the output shaft and facilitate stable extension and retraction of the output shaft. In addition, the bracket structure is also relatively simple.

[0023] In one specific example, the exhaust rod is fixedly connected to the output end of the telescopic cylinder through a connector 8, and a flared opening is formed at the upper part of the exhaust through hole, and the lower outer side of the connector is closed to match the flared opening. The advantage of this arrangement is that the force of the exhaust rod can be extended to the connector, which is beneficial to protecting the exhaust rod, and is also beneficial to reliably block the exhaust through hole and the exhaust port. It should be noted that in the specific setting, the length of the exhaust rod should be less than the thickness of the glue supply platen, so that the glue in the glue barrel can be used up when gluing.

[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.
