Abstract
Description
Technical Field
[0001] This application relates to the technical field of gaskets, and in particular to a gasket coating and cooling device. Background Technology
[0002] Bottled foods need to be sealed after processing. Sealing usually uses gaskets. Traditional gaskets have a three-layer structure: paper, aluminum foil, and film, with the paper facing outwards and the film facing inwards. Gaskets vary depending on the actual use; some are glued to the bottle opening, while others are glued to the bottle cap. When glued to the bottle cap, the gasket needs to be glued to the cap in order to adhere to it.
[0003] In the method of applying adhesive to the gasket before bonding it to the bottle cap, some adhesive initially penetrates the paper because the paper is the first point of contact with the adhesive. However, when the adhesive is applied to the inside of the bottle cap before bonding the gasket, the previously applied adhesive has already solidified, resulting in less penetration into the paper on the gasket. Therefore, compared to applying adhesive to the inside of the bottle cap first, the method of applying adhesive to the gasket before bonding requires a longer cooling time, thus reducing production efficiency. Further improvements are needed. Utility Model Content
[0004] To accelerate the curing rate of adhesive applied to gaskets, this application provides a gasket adhesive cooling device.
[0005] This application provides a gasket coating and cooling device, which adopts the following technical solution:
[0006] A gasket coating and cooling device includes a housing and a conveying assembly for conveying bottle caps with gaskets bonded to the housing. The housing has a chamber. The conveying assembly includes a frame, a transmission belt wound around the frame, and a drive component for driving the transmission belt. The opposite side walls of the housing are provided with through slots for the transmission belt to pass through, and the through slots are connected to the chamber. The housing is provided with a blower pipe for conveying cold air to the chamber.
[0007] By employing the above technical solution, cold air is delivered into the chamber through a blower to lower the chamber temperature. Through heat exchange, the adhesive cools and solidifies, thus accelerating the curing rate of the adhesive applied to the gasket. Compared to natural cooling at room temperature, this method takes less time. Furthermore, compared to applying adhesive to the bottle cap and then bonding the gasket to it, the cooling time is relatively shorter, minimizing the impact on production efficiency when bonding the gasket and cap in this way. Moreover, the use of cold air for cooling prevents the cap from being blown away or the gasket from the cap before the adhesive has solidified, reducing the possibility of weak adhesion between the two.
[0008] Preferably, the air outlet of the blower is directed toward the top wall of the housing.
[0009] By adopting the above technical solution, it is known that air cooling achieves a cooling effect. If a lower temperature is required, the required air velocity is also relatively high. Since the gasket is very light, when the air volume delivered by the air blower is large, the corresponding air velocity will also be high, which may cause the gasket to be blown away from the bottle cap. Therefore, the air outlet direction of the air blower is set to blow towards the top wall of the box, that is, to avoid the gasket and the bottle cap, thereby reducing the possibility of blowing the gasket away from the bottle cap or blowing the bottle cap over.
[0010] Preferably, a desiccant is provided inside the box, and a desiccant is also provided on the periphery of the box located in the slot.
[0011] By employing the above technical solution and incorporating a desiccant, the humidity inside the chamber is reduced, thereby minimizing the possibility of condensation on the bottle caps or gaskets due to excessive humidity in the chamber under air-cooled conditions. Furthermore, the area near the perforation is a point of hot and cold air exchange; condensation may occur on the bottle caps when cold air flows to the outside. Therefore, a desiccant is installed here to absorb moisture, reducing the possibility of water molecules flowing into the uncured adhesive layer.
[0012] Preferably, the two through slots include a first through slot for the bottle cap to enter the chamber with the conveyor belt and a second through slot for the bottle cap to leave the chamber with the conveyor belt. The air blowing pipe includes an air inlet pipe passing through the side wall of the box body near the first through slot and an air outlet pipe connected to the air inlet pipe. The length direction of the air outlet pipe is parallel to the length direction of the box body. Several air outlet pipes are spaced apart along the width direction of the box body. An air outlet is provided on the outer peripheral wall of the air outlet pipe near the top wall of the box body. Several air outlets are spaced apart along the length direction of the air outlet pipe.
[0013] By adopting the above technical solution, the air volume at the air outlet far from the air inlet will be reduced as the air outlet is set along the length of the air outlet pipe. This allows the glue on the bottle cap entering the box from the first through slot to exchange heat with the excess cold air, thus accelerating the solidification rate and effect.
[0014] Preferably, a transition box is provided on the side wall of the housing near the second through slot. The side wall of the transition box has a through hole for the transmission belt to pass through. A heating coil is provided inside the transition box. The heating coil contains a heat-conducting medium. The outer peripheral wall of the heating coil is covered with a heat insulation pad. The thickness of the heat insulation pad gradually decreases in the direction away from the second through slot.
[0015] By adopting the above technical solution, a transition box is provided, and a heating coil is provided inside the transition box. A heating medium flows in the heating coil. As the heat insulation pad provided on the heating coil gradually decreases in the direction away from the second through groove, the temperature of the transition box can gradually increase in the direction away from the second through groove. This reduces the possibility of excessive water droplets condensing on the bottle cap due to a large temperature difference when the bottle cap is in direct contact with the outside world, and also reduces the possibility of some water droplets penetrating into the adhesive layer.
[0016] Preferably, the spacing between adjacent pipes on the heating coil gradually increases towards the second through groove.
[0017] By adopting the above technical solution, the possibility of excessive temperature change after direct heat exchange can be further reduced.
[0018] Preferably, the outer peripheral wall of the heat insulation pad is provided with absorbent cotton.
[0019] By adopting the above technical solution and by setting up a water-washing cotton, some water molecules are absorbed during the heat exchange process, thereby reducing the amount of water droplets retained during the heat exchange process of the hot airflow flowing to the bottle cap.
[0020] Preferably, a guide plate is provided on the upper surface of the frame near the second through slot. The guide plate is disposed in the transition box, and the end of the guide plate away from the frame is inclined upward toward the second through slot.
[0021] By adopting the above technical solution, and by setting up an air guide plate, the cooler air is directed to the heating coil.
[0022] In summary, this utility model has the following beneficial effects:
[0023] 1. Cold air is delivered into the chamber through a blower to lower the temperature of the chamber. Through heat exchange, the adhesive is cooled and fixed, thereby accelerating the curing rate of the adhesive applied to the gasket. Compared with natural cooling in a room temperature environment, it takes less time, thus speeding up the bonding rate between the bottle cap and the gasket.
[0024] 2. By incorporating a desiccant, the humidity inside the chamber is reduced, thereby minimizing the possibility of condensation on the bottle caps or gaskets due to excessive humidity in the chamber under air-cooled conditions. Furthermore, the area near the perforation is a point of hot and cold air exchange; condensation may occur on the bottle caps when cold air flows to the outside. Therefore, a desiccant is installed here to absorb moisture, reducing the possibility of water molecules flowing into the uncured adhesive layer.
[0025] 3. By setting up a transition box, a heating coil is installed inside the transition box, and a heating medium flows in the heating coil. As the heat insulation pad installed on the heating coil gradually decreases in the direction away from the second through groove, the temperature of the transition box can gradually increase in the direction away from the second through groove. This reduces the possibility of excessive water droplets condensing on the bottle cap due to excessive temperature difference when the bottle cap is in direct contact with the outside world, and also reduces the possibility of some water droplets penetrating into the adhesive layer.

[0036] The opposite side walls of the housing 1 are provided with through slots 12 for the transmission belt 22 to pass through. The through slots 12 are connected to the chamber 11. For easy distinction, in this embodiment, the two through slots 12 are the first through slot 121 for the bottle cap to enter the chamber 11 with the transmission belt 22 and the second through slot 122 for the bottle cap to leave the chamber 11 with the transmission belt 22.
[0037] For the delivery of cold air, the housing 1 is provided with an air duct 3 for delivering cold air to the chamber 11.

(Referring to...) Figure 4 For the heating coil 7, which is arranged parallel to the height direction of the transition box 6, in this embodiment, the distance between the bend of the heating coil 7 and the conveyor belt gradually increases in the direction closer to the second through groove 122.
