Abstract
Description
Technical Field
[0001] This utility model relates to the field of hot melt adhesive supply technology, and in particular to a heating plate. Background Technology
[0002] Thermoplastic spacers (TPS) eliminate the use of heat-conducting metals like aluminum and stainless steel in traditional insulated glass. Insulated glass made with TPS has a significantly lower linear thermal conductivity than traditional products, effectively blocking heat loss from the glass edges and thus improving the overall energy efficiency of the window. TPS insulated glass has a lifespan 2-3 times longer than ordinary insulated glass and offers superior warm-edge performance. It provides a very low edge U-value, minimizing condensation at the edges. Due to its excellent performance, TPS insulated glass is used in passive house construction. TPS insulated glass features include: TPS thermoplastic spacers without metal embeddings; improved thermal barrier properties at the glass edges; a more even surface temperature distribution on both the inner and outer surfaces; effective reduction of condensation at the glass edges, inhibiting mold growth; flexible edge sealing; product diversity, making glass design more flexible and convenient; perfect compatibility with the glass assembly industry; high quality control; and a longer effective lifespan.
[0003] In the production process of TPS insulating glass, adhesive is supplied to an automatic coating machine via an adhesive supply machine. Existing adhesive supply machines, such as the adhesive supply device and method for a viscous adhesive supply system disclosed in patent application CN202110562117.9, include: a heating plate, which includes a heating plate body, a heating element and an adhesive discharge hole disposed on the heating plate body; an adhesive storage device for storing adhesive; a heating plate driving device for driving the heating plate to move; an adhesive pumping device connected to the adhesive discharge hole; and a gas flow path assembly, through which gas can be selectively injected into the adhesive storage device or discharged outwards. This technical solution achieves gas venting between the glue tank and the heating plate by designing a gas flow path component, and automatically seals the gas flow path component using viscous adhesive, eliminating the need for manual intervention, saving labor costs, and avoiding waste of adhesive. Furthermore, when changing the adhesive, positive pressure gas is introduced into the glue tank through the gas flow path component, and the positive pressure gas is used to push out the heating plate, or the positive pressure gas and the heating plate drive motor work together to efficiently remove the heating plate.
[0004] The above technical solution has some shortcomings. It requires the addition of a gas flow path component to the heating plate, which increases the overall thickness of the heating plate and makes the overall structure of the heating plate more complicated, making subsequent maintenance more troublesome.

[0033] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0034] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 as well as Figure 9As shown, the heating plate according to the embodiment of the present utility model includes a heating plate body 100. A mounting groove 110 for connecting to a glue pump 210 is provided at the center of the top surface of the heating plate body 100. A glue discharge hole 111 is provided through the mounting groove 110. An exhaust hole 120 is provided on the side of the heating plate body 100 near the mounting groove 110. A plurality of first mounting holes 130 are also provided on the top surface of the heating plate body 100 along the central axis of the heating plate body 100. A heating tube 131 is connected to each of the first mounting holes 130.
[0035] The bottom of the heating plate body 100 is connected to multiple protrusions, and each protrusion forms a colloid flow channel 150. Each colloid flow channel 150 is connected to the colloid discharge hole 111, and the exhaust hole 120 is connected to the colloid flow channel 150.
[0036] In actual use, by setting an exhaust hole 120 outside the mounting groove 110 and connecting it to the colloid flow channel 150, the gas in the glue bucket can be discharged while the glue is supplied. At the same time, the setting of the first mounting hole 130 makes it easy to disassemble and install the heating tube 131, and the heating tube 131 can be laid out more conveniently according to actual needs, so that the heating is more reasonable and the overall structure is simple and effective.
[0037] Specifically, the heating element 131 generates heat, which is then transferred through the heating plate body 100 to the adhesive in the glue bucket, causing it to soften and melt. During this process, the adhesive in the glue bucket changes from a state close to the heating plate body 100 towards the bottom of the glue bucket, successively into a fluid, a paste, and a solid.
[0038] In some specific embodiments of this utility model, it may also have the following additional technical features: the glue discharge hole 111 is eccentrically set.
[0039] The specific eccentric design of the glue discharge hole 111 makes it easy to use with the glue pump 210.
[0040] In some specific embodiments of this utility model, it may also have the following additional technical features: a second mounting hole 160 is also provided through the heating plate body 100, and a temperature sensor 161 is connected in the second mounting hole 160.
[0041] In some specific embodiments of this utility model, it may also have the following additional technical features: the glue discharge hole 111 is eccentrically located near the second mounting hole 160.
[0042] With the above design, the temperature sensor 161 can more easily and accurately monitor the temperature of the adhesive entering the glue pump 210, thus facilitating subsequent adjustments.
[0043] It should be noted that the heating element 131 and the temperature sensor 161 are both technical solutions commonly used by those skilled in the art. They can be obtained by consulting reference books and purchasing them on the market according to the actual needs and parameters. Their specific structure and principle will not be described in detail here.
[0044] In some specific embodiments of this utility model, it may also have the following additional technical features: the included angle between the line connecting the second mounting hole 160 and the center of the heating plate body 100 and the line connecting the exhaust hole 120 and the center of the heating plate body 100 is 90°.
[0045] Specifically, in addition to generating heat, the heating plate will also move downward under the pressure of the glue dispenser, thereby exerting pressure on the glue. At this time, the glue flows, and the gas carried by the flowing glue will be discharged through the exhaust port 120.
[0046] In some specific embodiments of this utility model, it may also have the following additional technical features: the diameter of the glue discharge hole 111 gradually increases from the top surface of the heating plate body 100 to the bottom surface of the heating plate body 100.
[0047] The above design allows the colloid to flow easily into the discharge hole 111.
[0048] In some specific embodiments of this utility model, it may also have the following additional technical features: the convex part has a fan-shaped structure, and the central axis of the convex part passes through the center of the heating plate body 100.
[0049] In some specific embodiments of this utility model, it may also have the following additional technical features: the protrusion includes a strip-shaped fan rib protrusion 141 and a plurality of arc-shaped fan surface protrusions 142 spaced apart on the strip-shaped fan rib protrusion 141. The plurality of arc-shaped fan surface protrusions 142 are symmetrically connected to the strip-shaped fan rib protrusion 141 about the central axis of the strip-shaped fan rib protrusion 141. The arc-shaped fan surface protrusions 142 connected to the same position on the strip-shaped fan rib protrusion 141 on different protrusions are spaced apart to form a circle with a notch. The gaps between two adjacent protrusions and the gaps between two arc-shaped fan surface protrusions 142 between two adjacent protrusions are connected to form a colloid flow channel 150.
[0050] Through the above design, the presence of the strip-shaped fan rib protrusion 141 and the arc-shaped fan surface protrusion 142 can increase the contact area with the colloid, thereby improving the heat exchange efficiency and the overall working efficiency.
[0051] In some specific embodiments of this utility model, it may also have the following additional technical features: the two ends of the colloid flow channel 150 are respectively connected to the glue discharge hole 111 and the bottom outer edge of the heating plate body 100.
[0052] The above design increases the flow space of the colloid, thereby avoiding dead zones in the colloid discharge process and making the discharge more efficient.
[0053] In some specific embodiments of this utility model, it may also have the following additional technical features: a circular array of multiple first mounting holes 130 spaced apart around the heating plate body 100.
[0054] The above design makes the heat generation more uniform and effective.
[0055] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
