Description

Technical Field

[0001] The utility model relates to the field of hollow glass production, in particular to a TPSS thermoplastic warm edge spacer strip heating device. 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, it is necessary to first glue the edge of a piece of glass to initially form a spacer, and then heat the spacer to bond another piece of glass. Chinese patent CN202320698930.3 provides a device for heating the edge of glass, which supports the glass through supporting structures such as a support rack, an upper roller and a middle roller, and heats the glass through a horizontal heating module and a vertical heating module. Although the heating module can be adjusted to heat glass of different sizes, its supporting structure cannot adapt to glass support of different sizes. For example, when the size of the glass is almost the height of the middle roller, only the upper and lower parts of the glass are supported, and the middle part is suspended. If the glass is heated at this time, the middle part will become soft and bent, which not only affects the heating but also poses a risk of glass falling. Utility Model Content

More importantly, the two are connected through a transmission mechanism, and on the one hand, the second driving member can drive both to move at the same time, and the structural arrangement is more reasonable and simple; on the other hand, when the upper crossbeam is adjusted, the middle crossbeam can be adjusted accordingly so that it is always in the middle of the upper crossbeam and the lower crossbeam, so that no matter what the size of the glass is, it can be adjusted to a suitable position to achieve stable support for the glass.

The upper crossbeam 6 and the middle crossbeam 5 are specifically arranged on the guide rail 13 through a slider, and the upper crossbeam 6 is driven to move up and down by the second driving member 14, and the middle crossbeam 5 can move with the upper crossbeam 6 through a plurality of groups of transmission mechanisms 15; the transmission mechanism 15 includes a transmission chain 1501 and a transmission gear 1502, and the transmission gear 1502 is fixed on the rear side of the middle crossbeam 5, one end of the transmission chain 1501 is fixed to the upper part of the frame 1, and the other end is fixed to the upper crossbeam 6 after bypassing the transmission gear 1502, so that the moving distance of the middle crossbeam 5 is half of the moving distance of the upper crossbeam 6.

[0027] Further, such as Figure 4 As shown, the first driving member 12 includes a transverse conveyor belt or a transverse conveyor chain, and a transverse guide rail for limiting the sliding of the left vertical beam is provided on one side of the transverse conveyor belt. The left vertical beam 7 is fixedly connected to the transverse conveyor belt through a first connecting member, so as to drive the left transverse beam to move left and right along the transverse guide rail as the transverse conveyor belt runs forward and backward. Figure 2 As shown, the second driving member 12 includes a vertical conveyor belt, and the upper crossbeam 6 is fixedly connected to the vertical conveyor belt through a second connecting member, so as to drive the upper crossbeam to move up and down along the vertical guide rail as the vertical conveyor belt runs forward and backward.

Whether it is the left vertical beam or the upper crossbeam, both ends of the left vertical beam and the upper crossbeam need to be provided with conveyor belts, and the conveyor belts at both ends can be driven by a transmission shaft and a servo motor to achieve synchronous movement.

[0028] Regarding the feeding mechanism, it can realize the movement of glass through multiple rollers arranged in parallel, and a chain and a motor cooperating with one end of the roller. Since the feeding mechanism is a prior art, it will not be described in detail here.

[0029] Furthermore, a plurality of guide wheels 16 are sequentially arranged on the upper crossbeam 6 , the middle crossbeam 5 and the lower crossbeam 4 at intervals along the feeding direction.

[0030] Working principle:

[0031] Process 1: After the glass size is determined in the early stage, the heating device begins to adjust adaptively. Specifically, the second driving member 14 will slide the upper beam 6 along the vertical guide rail 13. Under the action of the transmission mechanism 15, the middle beam 5 will slide along the vertical guide rail 13 until it moves to a suitable position. The moving distance of the middle beam 5 is half of the moving distance of the upper beam 6. In this way, the middle beam 5 can always be in the middle of the upper beam 6 and the lower beam 4, realizing effective support for the upper, middle and lower positions of the glass. The upper beam 6 and the middle beam 5 adopt a linkage mode, which can facilitate the reasonable arrangement of each structure without affecting the supporting function. During the above process, the first driving member 12 will also move the left vertical beam 7 until it moves to a suitable position. Among them, a horizontal upper heating member 10 is provided on the upper beam 6, a horizontal lower heating member 11 is provided near the lower beam 4, and a vertical heating member 9 is provided on the left vertical beam 7 and the right vertical beam. After waiting for the glass to be transported, the heating members in four directions can cover and heat the spacer strips at the edge of the glass.

[0032] Process 2: The glass is transported to the heating device. When the glass detection switch 3 detects the glass, the glass will stop at this position for heating. After the heating is completed, it can be transported to the next process.

[0033] In one specific embodiment, Figure 2 or Figure 5 As shown, the upper beam 6 is connected to a shield 17 extending forward above the guide wheel 16, and a horizontal upper heating element 10 is arranged in front of the glass in the shield 17. The heating elements in four directions of the glass are all located in front of the glass, so that the spacer strips can be heated directly, and the heating speed is faster.

[0034] In one specific embodiment, the glass detection switch 3 may be a diffuse reflection type photoelectric sensor.

[0035] In one specific embodiment, Figure 4 As shown, the glass detection switch 3 includes a deceleration switch and a stop switch which are sequentially arranged along the feeding direction. Such an arrangement can not only ensure the early conveying efficiency, but also can safely and stably realize the glass stopping and heating operation.

[0036] In one specific embodiment, the vertical heating element 9, the upper horizontal heating element 10 and the lower horizontal heating element 11 are heated by electric heating tubes, and a protective cover is also provided in front of the lower horizontal heating element. Figure 6 As shown, a heat reflection cover 18 is provided on the left vertical beam 7 and the right vertical beam 8, and the vertical heating element 9 is provided in the heat reflection cover. The above arrangement can not only protect the electric heating pipe, but also help to improve the heating efficiency.

[0037] In one specific embodiment, for aesthetic and protection purposes, a protective cover is provided on the frame in front of the first driving member 12. A dustproof plate is also provided on the rear side of the frame.

[0038] 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.

[0039] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
