Description

Technical Field

[0001] The invention belongs to the technical field of resin tile cooling, and in particular relates to a cooling structure of a twin-screw extruder for producing resin tiles. Background Art

[0002] Resin tiles are tiles supported by highly weather-resistant engineering resin. Resin tiles are divided into natural resin tiles and synthetic resin tiles. The resin on the market is generally synthetic resin tiles. Resin tiles are mainly used in flat-to-slope projects, mobile homes, high-end villas, antique buildings, garden pavilions, factories, villas, real estate projects, awnings and sunshades, etc.

In this arrangement, it is ensured that the coolant can enter the connecting pipe 303 through the circular through holes 3031 .

[0047] Embodiment 3:

[0048] The difference between the above embodiment and this embodiment is that: Figure 1 and Figures 4 to 9 As shown, a cooling structure of a twin-screw extruder for producing resin tiles, the third moving mechanism includes a plurality of moving plates 402, each of which is fixedly connected to one end of a cam 4012 with two symmetrical moving rods 4021, and a sliding mechanism is arranged above each moving plate 402.

[0051] The implementation principle of the cooling structure of a twin-screw extruder for producing resin tiles in this embodiment is as follows:

[0052] First, the staff places the resin tile on the transmission unit 100 (the transmission unit 100 is a prior art), and the transmission unit 100 can transmit the placed resin tile;

[0053] When the resin tile is transferred to the bottom of the installation unit 200, the staff starts the motor 301. When the motor 301 is running, it can drive the rotating rod 3011 to rotate. When the rotating rod 3011 rotates, it can drive the guide sleeve 3012 in the guide slide groove 3013 and the guide slider as well as the limit rod 302, the extrusion plate 3021 and the second slide rail 3024, so that the guide sleeve 3012 can move up and down. When the guide sleeve 3012 moves downward, it can drive the limit rod 302 to drive the extrusion plate 3021 to move downward. When the extrusion plate 3021 moves downward, it can drive the connecting pipe 303, the connecting pipe 3032 and the hose 3033 to move downward.

[0054] When the connecting pipe 3032 moves downward, it can drive the rotating drum 4011 that is fitted together to rotate with the assistance of the rotating shaft 401 (because the connecting pipe 3032 and the rotating drum 4011 are tightly fitted, the rotating drum 4011 can be rotated driven by the friction force when the connecting pipe 3032 moves downward), and when the rotating shaft 401 rotates, it can drive the cam 4012 to rotate, and when the cam 4012 rotates, it can push the moving rod 4021 to drive the moving plate 402 to move horizontally with the assistance of the moving slide groove 4022 and the moving slider 4023 in the sliding mechanism;

[0055] When the movable plate 402 moves, it will be able to drive the fixed plate 403 to move, and when the fixed plate 403 moves, it will be able to drive the push plate 4031 away from the hose 3033, so that the hose 3033 can be reset under its own elasticity, thereby adjusting the position of the spray head 3034 on the front side of the hose 3033, so as to achieve a more comprehensive spraying of the resin tile, so that when the resin tile is cooled, its cooling effect is better (when the movable plate 402 moves downward, because the coolant is located in the inner cavity of the cooling box 204 and in The piston plate 3022 is above the movable plate 402, and when the movable plate 402 moves downward, the piston plate 3022 is stationary with the assistance of the connecting rod 3023, so the movable plate 402 will be separated from the piston plate 3022, so that the groove at the place where the movable plate 402 and the piston plate 3022 are originally sealed is opened, so that the coolant above can enter the bottom of the movable plate 402, and the coolant can enter the inner wall of the connecting pipe 303 from the circular through hole 3031 opened at the connecting pipe 303, and then enter the inner cavity of the connecting pipe 3032);

[0056] When the guide sleeve 3012 moves downward, it will be able to drive the positioning rod 305, the placement plate 3051 and the baffle 3052 to move downward. When the baffle 3052 moves downward, it will be able to drive the movable rod 3053 to move downward. When the movable rod 3053 moves downward, it will be able to push the cleaning plate 2035 to move horizontally with the assistance of the first slide rail 2021. When the cleaning plate 2035 moves, it will be able to push the flip plate 2034 in the flip mechanism to open with the assistance of the rotating rod 203, so that the debris on the cleaning plate 2035 can be cleaned.
