Description
Technical Field

[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 supplied to the gluing head through a glue supply mechanism. In addition to high requirements for glue supply continuity, higher requirements are also placed on glue supply stability. However, due to the several-meter-long glue supply hose connecting the glue supply mechanism and the gluing head, the distance and insufficient early exhaust make it impossible for the thermoplastic warm edge spacer glue to be accurately delivered to the gluing nozzle, which affects the glue stability and thus affects the product quality. Utility Model Content

[0019] like Figure 1-3As shown, in this embodiment, the TPSS glue-spraying mechanism which is easy to adjust and measure comprises a glue-spraying frame 1, one side of the glue-spraying frame 1 is provided with a glue supply joint 2, a gear metering pump 3 and a glue-spraying component 4 which are sequentially connected through a first pipe section 5 and a second pipe section 6, a glue supply channel which is connected to the first pipe section 5 is formed in the glue supply joint 2, a pneumatic glue cylinder 7 is connected to the top of the glue supply joint 2, the pneumatic glue cylinder 6 comprises a glue cylinder body 701, a heating coil 702 is provided on the outer jacket of the glue cylinder body 701, and a mica heating coil can be used specifically, a glue piston 703 is provided in the glue cylinder body 701, so as to form a glue supply channel under the glue piston 703. A connected glue storage chamber 704 is provided, on which a glue piston rod 705 is connected. A cylinder 707 is invertedly installed above the glue cylinder body 701 through a bracket 706. The output end of the cylinder 707 is connected to the upper end of the glue piston rod 705 through a coupling 708, so that the glue piston 703 can be driven to replenish glue in the glue supply channel. A pressure sensor 10 is provided at the output end of the glue supply channel. An electronic ruler 8 is connected to the side of the cylinder body of the cylinder. An electronic ruler end plate 9 is connected to the side of the coupling 708. The floating joint of the electronic ruler 8 is connected to the electronic ruler end plate 9 to measure the amount of glue entering the glue storage chamber 704.
[0020] Working principle: before glue application, the gear metering pump is started to speed up the transfer of glue in the glue supply pipe toward the glue supply joint. Before the glue is discharged from the glue application part, glue can be continuously transferred to the glue storage chamber 704 for storage. During storage, the cylinder 707 will release pressure so that the glue piston 703 can push the glue piston rod 705 and the piston rod of the cylinder 707 upward in turn. When the electronic ruler 8 measures a certain amount of glue, it stops, and then the glue application part can be started to start the glue application operation. When the pressure sensor 10 detects that the glue pressure is reduced, the cylinder 707 will drive the glue piston 703 to move downward to the glue supply channel to pass the glue, and stop when the pressure sensor 10 detects that the glue pressure reaches the standard range. At this time, the glue pressure delivered by the glue supply channel is relatively stable, so it is convenient for the metering pump to accurately measure and stably transfer glue backward to the glue application head.
[0021] In one specific embodiment, the glue applying component 4 includes an electric slip ring 401 and a glue applying head 403 connected to the second pipe section 6 through a rotary joint 402, the rotor of the electric slip ring 401 is fixed outside the rotary joint 402, the stator of the electric slip ring 401 is relatively fixed outside the second pipe section 6, the rotor is connected to a driven gear 404, the driven gear 404 is meshed with a driving gear 405, and the driving gear 405 is driven by a servo motor 406 fixed to the glue applying frame 1, so as to realize the glue applying head 403 to rotate and apply glue. The above structure is reasonably arranged, and can realize the glue applying head to rotate and apply glue, which is conducive to ensuring a good glue applying quality.
[0022] Among them, two spaced fixing plates are provided on the side of the glue rack 1, and the fixing plates are provided with mounting holes, and the second pipe section 6 is provided through the mounting holes, and the stator of the electric slip ring 401 is fixed between the two fixing plates outside the second pipe section 6, and the servo motor 406 is provided below the stator. The above structures not only look simple and compact, but also have high connection firmness.
[0023] In one specific embodiment, the bracket 706 includes a lower positioning ring fixed to the glue cylinder body 701 and an upper positioning ring fixed to the cylinder body of the cylinder 707, and a plurality of positioning rods are connected between the lower positioning ring and the upper positioning ring outside the glue piston rod. A reinforcing plate is also connected between the bracket 706 and the glue rack 1. Such a configuration will help increase the connection firmness and the smoothness of glue supply.
[0024] In one specific embodiment, a dust cover 709 is provided on the top of the rubber cylinder 701 to prevent dust from entering the rubber cylinder.
[0025] 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.
