Description

Technical Field

[0001] This utility model relates to the field of adhesive melting device technology, specifically to an online adhesive melting device. Background Technology

[0002] The production of composite adhesive films involves uniformly coating molten resin at a specific temperature onto release paper or other carriers. The resin temperature significantly affects its viscosity, severely impacting coating quality; therefore, maintaining the resin temperature during operation is crucial. The common practice is to heat the resin, stored at low temperatures, to a set temperature in an oven, then pour it tray by tray into a coating machine for production. This method is extremely labor-intensive; furthermore, the quantity to be baked needs to be estimated and calculated—too much is wasteful, while too little results in unsuitable film production.

[0003] Therefore, some online melting devices have emerged on the market, such as online dispensing rack melting devices, online double-roller melting devices, and screen melting devices. However, online dispensing rack melting devices and online double-roller melting devices have problems such as insufficient melting, insufficient melting capacity, and inability to meet the melting requirements of high-viscosity resins. Traditional screen melting devices also have problems such as easy material accumulation and tangling in the melting tank, which will affect the melting speed and uniformity. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an online melting device that can solve the problems of easy material accumulation and roll-up in the melting tank of traditional mesh curtain melting devices, which affect the melting speed and uniformity.

[0006] In one embodiment, the melting system includes a drive roller, a melting hot plate, a heat preservation plate, a mesh curtain, and a second actuator. The mesh curtain covers the drive roller, the melting hot plate, and the heat preservation plate. The second actuator is connected to the drive roller and drives the drive roller to rotate, thereby moving the mesh curtain from the melting hot plate to the heat preservation plate and circulating it. The glue tank is provided on the upper surface of the melting hot plate for heating the mesh curtain and melting the glue block. The lower end of the heat preservation plate is located above the coating roller and is used to keep the glue liquid on the mesh curtain warm and transfer the glue liquid to the working glue tank of the coating roller.

[0007] In one embodiment, the melting system further includes a preheating plate, through which the mesh curtain is preheated before moving to the melting hot plate.

[0008] In one embodiment, the hot melt plate is connected to a tilting drive device, which drives the hot melt plate to rotate, causing the hot melt plate to detach from the mesh curtain.

[0009] In one embodiment, a heat insulation cover is provided on the upper surface of the insulation board.

[0010] In one embodiment, a scraper is provided at the lower end of the insulation board, and a cover plate is provided on the scraper.

[0011] In one embodiment, the second actuator includes a chain, a drive motor, and a chain tensioning cylinder; the chain is sequentially engaged with sprockets at one end of each drive roller; after the chain tensioning cylinder tensions the chain, the drive motor drives the drive wheel engaged with the chain to rotate, so that the chain drives the drive roller to drive the mesh curtain to rotate.

[0012] In one embodiment, the melting system further includes a third actuator, a fourth actuator, a distance sensor, a proximity switch, and a fifth actuator. The third actuator tensions the mesh curtain. The distance sensor is used to detect the deviation of the mesh curtain in real time. The fourth actuator adjusts the position of the mesh curtain online in real time based on the deviation detected by the distance sensor. Two proximity switches are respectively located on both sides of the mesh curtain. When either side of the mesh curtain touches the proximity switch, the online melting device alarms and automatically stops. The movable end of the fifth actuator is connected to the proximity switch on the operating side and is used to drive the proximity switch away from the mesh curtain when it needs to be replaced.

[0013] In one embodiment, a level and temperature sensor is provided on one side of the working glue tank to collect the temperature and level of the glue solution in the working glue tank; the level and temperature sensor is communicatively connected to the main control system; the main control system is communicatively connected to the melting glue system and is used to adjust the running speed of the screen and the temperature of the melting glue hot plate according to the feedback information from the level and temperature sensor.

[0036] Please see Figures 1-11The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0037] It should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings of this specification are only used to complement the content disclosed in the specification for those skilled in the art to understand and read, and are not intended to limit the conditions under which this utility model can be implemented. Therefore, they have no substantial technical significance.

The term “connection,” unless otherwise specified, includes both direct and indirect connections.

[0039] To avoid confusion with this utility model, some technical features known in the art have not been described.

[0040] like Figures 1 to 8 As shown, this embodiment provides an online glue melting device 100, including a flipping bracket 110, a glue melting system 120, and a glue tank 130. The flipping bracket 110 is fixedly mounted on the upper surface of an operating table (not shown in the figure). The glue melting system 120 is rotatably connected to the flipping bracket 110 via a slewing bearing 111, and is used to melt glue blocks and convey melted glue to a coating roller 200. The glue tank 130 is disposed on the upper surface of the glue melting system 120 and is used to hold glue blocks, which can be resin. Further, the glue tank 130 includes a tank body 131, a baffle plate 132, and a hot glue melting roller 133. The baffle plate 132 is disposed within the tank body 131, and the position of the baffle plate 132 within the tank body 131 is adjustable, thereby allowing the width of the tank body 131 to be adjusted. The hot melt roller 133 is set on the glue outlet side of the trough 131 to increase the glue melting capacity on the outlet side. It can prevent the softened glue block from flipping over the hot melt roller 133, and can prevent the glue trough 130 from having problems such as easy material accumulation and material roll-up, thereby improving the speed and uniformity of glue melting.

[0041] Specifically, the tumbling motion of the melting system 120 relative to the tumbling support 110 is controlled by the first actuator 140. The first actuator 140 can be a pneumatic cylinder or an electric cylinder, with its fixed end fixed to the upper surface of the operating table and its movable end connected to the melting system 120. It is used to push the melting system 120 to rotate around the slewing bearing 111, thereby causing the melting system 120 as a whole to switch its dispensing position relative to the coating roller 200 to adapt to unidirectional coating (e.g., ...). Figure 7 (as shown) or reverse coating (as shown) Figure 8 As shown in the diagram, when it is necessary to replace the mesh curtain 125, the entire molten adhesive system 120 can be rotated to the top of the operating table via the first actuator 140. After removing the adhesive tank 130, the belt-type molten adhesive mesh curtain 125 can be quickly replaced.

[0042] like Figure 3 As shown, the adhesive melting system 120 includes two side connecting plates with a trapezoidal side projection, and a drive roller 121, a preheating plate 122, an adhesive melting hot plate 123, and an insulation plate 124 sequentially arranged between the two side connecting plates. The drive roller 121 is located at the four corners of the side connecting plates, and the preheating plate 122, the adhesive melting hot plate 123, and the insulation plate 124 are respectively arranged between the two drive rollers 121. A mesh curtain 125 covers the drive roller 121, the preheating plate 122, the adhesive melting hot plate 123, and the insulation plate 124. The drive roller 121 is used to drive the movement of the mesh curtain 125; the preheating plate 122 is used to preheat the mesh curtain 125; the adhesive melting hot plate 123 is used to heat the mesh curtain 125; and the insulation plate 124 is used to keep the adhesive on the mesh curtain 125 warm and transfer the adhesive to the coating roller 200. In the molten state, the hot plate 123 is in a horizontal position, and the glue tank 130 is positioned above the hot plate 123. The insulation plate 124 is inclined and positioned on the glue outlet side of the hot plate 123. The rotation of the drive roller 121 is driven by the second actuator, which drives the movement of the screen curtain 125. After being preheated by the preheating plate 122, the screen curtain 125 enters the glue tank 130. The hot plate 123 melts the glue block in the glue tank 130, and the screen curtain 125 carries away the melted glue liquid, which is then transferred to the top of the coating roller 200 via the insulation plate 124. A scraper 126 is provided at the lower end of the insulation plate 124, which scrapes the glue liquid onto the coating roller 200. After the glue is dispensed, the screen curtain 125 continues to move, passes through the preheating plate 122 again, and then enters the glue tank 130, thus completing the cycle.

[0043] Please combine Figure 2 and Figure 3The second actuator is located on the side connecting plate near the tilting bracket 110 and includes a chain 151, a drive motor 152, and a chain tensioning cylinder 153. The chain 151 is sequentially engaged with the sprockets at one end of each drive roller 121. After the chain tensioning cylinder 153 tensions the chain 151, the drive motor 152 drives the drive wheel engaged with the chain 151 to rotate, so that the chain 151 can drive the drive roller 121 to drive the mesh curtain 125 to rotate.

[0044] Furthermore, in order to control the mesh curtain 125 to remain taut, a third actuator 160 (e.g., a tensioning cylinder) for tensioning the mesh curtain 125 can be added to the side connecting plate.

[0045] Furthermore, to prevent the net curtain 125 from deviating, a fourth actuator 171 (e.g., an electric push rod) and a distance sensor 172 can be added to the side connecting plate near the flipping bracket 110. The movable end of the fourth actuator 171 is connected to the drive roller 121 below the preheating plate 122. The distance sensor 172 is set directly opposite the drive roller 121 below the preheating plate 122 to detect the deviation of the net curtain 125 in real time. The fourth actuator 171 pushes the drive roller 121 below the preheating plate 122 to adjust its position according to the deviation detected by the distance sensor 172, thereby adjusting the position of the net curtain 125 online in real time.

[0046] Furthermore, such as Figure 3 and Figure 4 As shown, a proximity switch 180 is provided on each side of the mesh curtain 125. When the mesh curtain 125 deviates beyond its maximum position to either side of the side connecting plate, the mesh curtain 125 can trigger the proximity switch 180, activating the main control system 400 (e.g., Figure 5 (As shown) It issues an alarm and controls the online melting device 100 to automatically stop. The proximity switch 180 on the operating side is connected to the movable end of the fifth actuator 190 (e.g., a cylinder). When the screen curtain 125 needs to be replaced, the fifth actuator 190 drives the proximity switch 180 on the operating side to move away from the screen curtain 125 so that the screen curtain 125 can be smoothly removed from the operating side.

[0047] like Figure 9 As shown, to facilitate the separation of the hot melt plate 123 from the mesh curtain 125 and to control the temperature of the adhesive, a tilting drive device (pneumatic or electric cylinder) can be added to the side connecting plate to drive the hot melt plate 123 to rotate and tilt. Simultaneously, when the machine stops, this design allows the hot melt plate 123 to detach from the mesh curtain 125, preventing excessive melting of the adhesive block during abnormal shutdowns.

[0048] like Figure 10 As shown, a heat insulation cover 127 can be added to the upper surface of the insulation board 124 to reduce the temperature loss of the adhesive caused by the mesh curtain 125 when it is transported on the insulation board 124.

[0049] like Figure 11 As shown, since the screws on the scraper 126 are prone to loosening during use, a cover plate 128 can be added to the scraper 126 to prevent the screws from falling off.

[0050] Furthermore, such as Figure 6 As shown, a liquid level and temperature sensor 300 can be installed on one side of the working glue tank 201 of the glue coating roller 200 to collect the temperature and liquid level of the glue in the working glue tank 201 and feed it back to the main control system 400. The main control system 400 adjusts the running speed of the screen curtain 125 of the online glue melting device, as well as the temperature on the preheating plate 122 and the glue melting hot plate 123, according to the liquid level and temperature information, so as to realize the online real-time control of the glue application amount according to the glue application amount of the glue coating machine.

[0051] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
