Description

Technical Field

[0001] The utility model relates to the technical field of resin block melting, in particular to a device for maintaining the temperature of the glue environment of a glue coating machine. Background Art

[0002] The melting process heats the resin block, transforming it from a solid to a liquid. Thermosetting resin coating machines typically use a water-circulating baking rack for curing. To ensure the lifespan of the thermosetting resin, the thermosetting resin blocks must be stored in a cold storage at -18°C. During coating, the resin blocks are removed from the cold storage and placed on a water-circulating baking rack, where they are heated and melted, flowing into the resin tank for coating.

[0003] Chinese patent CN211307033U discloses a solid resin hot melting mechanism, comprising an upper frame and a lower frame. Two support tubes are arranged across the upper frame, and fixed plates are provided at both ends of the support tubes. The fixed plates are arranged across and fixed to the support tubes. A cover plate is provided above the fixed plates. A melting frame is arranged across between the two fixed plates. A melting plate is provided below the melting frame. The melting plate is arranged at an angle. A fixed support shaft is provided on the lower back side of the melting plate, and the two ends of the fixed support shaft are placed in a bearing seat. The bearing seat is fixed to the lower frame. A rotating support shaft is provided on the upper back side of the melting plate, and the two ends of the rotating support shaft are placed in the bearing seat. The bearing seat is fixed to the lower frame. A storage tank is provided directly below the resin liquid flow outlet on the lower side of the melting plate. The utility model can fully melt the solid resin and facilitate the cleaning of the mechanism.

[0004] In the above patent, when the ambient temperature of the glue-making rack is high in the summer, the cold resin can be easily melted from the baking rack and flow into the glue tank. However, when the ambient temperature in winter is generally lower than 10°C, the temperature of the cold resin blocks after being piled up is low. When the water circulation baking rack is used alone for glue-making, only the bottom layer of glue blocks contacts the baking rack, and the glue-making speed is slow, which in turn affects the efficiency of subsequent operations.

The maintenance cover 5 is made of high-temperature resistant PET foam boards bonded together to form a cover sealed on the left, right, back and top sides, which covers the glue baking rack 6, and then uses the blower 1 and the heater 3 to blow hot air into the maintenance cover 5, so that the glue baking rack 6 area can maintain an ambient temperature of 30-40°C, thereby accelerating the glue coating speed in winter. The top plate of the maintenance cover 5 is installed with a conveying pipe 4, and the end of the conveying pipe 4 away from the maintenance cover 5 is installed with a heater 3, and the heater 3 is connected to the blower 1 through a connecting pipe 2, and the air outlet end of the blower 1 and the connecting pipe 2 One end of the connecting pipe 2 is connected by a flange, the other end of the connecting pipe 2 is connected to the air inlet end of the heater 3 by a flange, and the air outlet end of the heater 3 is flange-connected to the delivery pipe 4.

[0027] Working principle of this utility model:

[0028] Refer to the instruction manual Figure 1-7 First, place the connecting rod 8 on the glue baking rack 6 between the support rod 7 and the guide rod 21, push the glue baking rack 6 inward to move horizontally, and the glue baking rack 6 drives the connecting rod 8 to move. When the inclined surface on the connecting rod 8 contacts the inclined surface of the insertion rod 19, the connecting rod 8 will make the insertion rod 19 slide on the maintenance cover 5. The insertion rod 19 drives the spring 18 to stretch through the movable plate 17. When the connecting rod 8 moves, the insertion rod 19 will slide on it. When the slot 22 on the connecting rod 8 and the insertion rod 19 move to the opposite side, the connecting rod 8 will slide on the support rod 7 and the guide rod 21 will move inward. When the resin block is in the desired position, the spring 18 returns to its original position under the action of the spring 18, so that the rod 19 is inserted into the slot 22, and the installation of the glue baking rack 6 is completed; the resin block is placed on the glue baking rack 6, and the glue is circulated by the water in the glue baking rack 6. At the same time, the blower 1 and the heater 3 are started, and the blower 1 sucks the gas from the connecting pipe 2 to the heater 3 for heating. The heated gas enters the maintenance cover 5 through the delivery pipe 4, and the gas is evenly distributed on the glue baking rack 6 through the hot air distributor 16. The resin block is evenly heated, which promotes the melting of the cold resin block; after the melting of the resin block is completed, when the glue baking rack 6 needs to be disassembled and cleaned, the motor 12 is started to drive the screw rod 14 to rotate, and the screw rod 14 causes the driving block 13 to slide down on the maintenance cover 5, and the driving block 13 causes one end of the movable rod 15 to rotate and move down, and the other end of the movable rod 15 rotates on the L-shaped rod 9 and makes it slide on the fixed rod 25, and the L-shaped rod 9 drives the sliding rod 11 to slide in the slide groove 10, and the L-shaped rod 9 moves to the movable plate 17. When in contact, the movable plate 17 is pushed to drive the insertion rod 19 to move outward and disengage from the slot 22. When the insertion rod 19 is completely out of the slot 22, the motor 12 is turned off and the glue baking rack 6 is taken out for cleaning, which makes it easy to take out the glue baking rack 6. By arranging the blower 1, the heater 3 and the hot air distributor 16 and other structures in conjunction with the glue baking rack 6, the problem of slow glueing speed when the glue baking rack 6 is used alone when the ambient temperature is low is solved.
