[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-4 As shown, this utility model embodiment provides a floor extrusion device with a flatness adjustment structure, including a rectangular forming cavity 103 for shaping molten material into a sheet shape. The inlet end of the rectangular forming cavity 103 is connected to a feeding component for providing molten material. The outlet position of the rectangular forming cavity 103 is provided with a cutting component for cutting the sheet. Downstream of the rectangular forming cavity 103 is a first flattening component for pre-conditioning the sheet. Downstream of the first flattening component is a receiving component for receiving the sheet and a second flattening component for secondary flattening of the sheet. Through two flattening processes, the quality of the sheet is guaranteed.

[0029] The first leveling component includes a first conveyor belt 206 for carrying the sheet material. First conveyor rollers are provided on both sides of the first conveyor belt 206. The ends of the first conveyor rollers are rotatably connected to the first bracket 208. The first conveyor rollers are driven by a first motor 207. A leveling roller 205 is provided above the first conveyor belt 206. The two ends of the leveling roller 205 are rotatably mounted on a vertical plate. The gap between the leveling roller 205 and the first conveyor belt 206 corresponds to the thickness of the sheet material. When the formed sheet material comes out along the rectangular forming cavity 103, the leveling roller 205 matches the first conveyor belt 206, thereby performing a preliminary leveling operation on the sheet material.

[0030] The second leveling component includes a flattening push rod 400 disposed above the second conveyor belt 304. The flattening push rod 400 is mounted on a mounting frame (not shown). The output end of the flattening push rod 400 is connected to a flattening frame 401. A pressing plate 403 is fixedly disposed at the lower end of the flattening frame 401. The lower end of the pressing plate 403 has a polished surface. A semiconductor cooling plate is embedded at the upper end of the pressing plate 403. A heat dissipation unit is arranged at the upper end of the semiconductor cooling plate. During the secondary leveling process, the flattening push rod 400 drives the flattening frame 401 and the pressing plate 403 to move downward, so that the pressing plate 403 presses down on the plate on the second conveyor belt 304. A vibration motor is disposed on the pressing plate 403 to assist in the flattening process of the plate. During the operation, the semiconductor cooling plate can cool and shape the plate.

[0031] The heat dissipation unit includes multiple heat dissipation fins 402 disposed on the upper end of the pressure plate 403. One end of the pressure plate 403 is provided with a heat dissipation fan unit 404 that accelerates airflow. The arrangement direction of the heat dissipation fins 402 corresponds to the airflow direction. By accelerating the airflow through the heat dissipation fan unit 404, the heat dissipation area is increased in conjunction with the heat dissipation fins 402, thereby enabling the lower end surface of the pressure plate 403 to have a long-lasting cooling effect.

[0032] The receiving assembly includes a rotary motor assembly 300. The output end of the rotary motor assembly 300 is provided with a switching frame 302. Each end of the switching frame 302 is provided with a second support 303. A second conveyor belt 304 is provided on the upper end of each second support 303. Second conveyor rollers are matched to both ends of the second conveyor belt 304. The two ends of the second conveyor rollers are rotatably connected to a central support 301. A horizontal plate 500 is also provided between the central supports 301 to support the bottom of the upper second conveyor belt 304. The horizontal plate 500 is connected to a mechanism for lifting the second conveyor belt 304 upwards. The push rod 501 of the second conveyor belt 304 prevents deformation of the second conveyor belt 304 from affecting the forming of the sheet. The end of the second conveyor roller is driven by the second motor 305. Under the drive of the second motor 305, the second conveyor roller drives the second conveyor belt 304 to rotate, thereby transferring the formed sheet. The rotating motor group 300 drives the switching frame 302 to rotate. The switching frame 302 will transfer the unloaded second conveyor belt 304 to the downstream of the first leveling component to complete the receiving of materials. Then, by switching the positions of the two second conveyor belts 304, continuous processing can be achieved.

[0033] The cutting assembly includes a cutting blade 200 corresponding to the discharge port of the rectangular forming cavity 103. The upper end of the cutting blade 200 is connected to the output end of the cutting push rod 201. The fixed end of the cutting push rod 201 is connected to the cutting positioning frame 204. The two ends of the cutting positioning frame 204 are mounted on the upper end of the rectangular forming cavity 103. Two cutting guide rods 202 are symmetrically provided on the upper end of the cutting blade 200. The cutting positioning frame 204 is provided with a cutting guide sleeve 203 that matches the cutting guide rods 202. The cutting blade 200 is driven to move downward by the cutting push rod 201. The cutting blade 200 will slide up and down along the cutting guide rods 202 and the cutting guide sleeve 203 so as to cut the extruded sheet into the target size.

[0034] The feeding assembly includes a horizontally arranged extrusion conveyor cylinder 100. The discharge end of the extrusion conveyor cylinder 100 is connected to the feed end of the rectangular forming cavity 103. An extrusion screw is provided inside the extrusion conveyor cylinder 100. The extrusion screw is driven by an extrusion motor 104. Under the drive of the extrusion motor 104, the extrusion screw can extrude the molten material into the rectangular forming cavity 103, thereby completing the preliminary forming of the sheet. The upper port of the extrusion conveyor cylinder 100 is connected to the molten feeding cylinder 102. A heating pipe for heating the molten material is provided on the outside of the molten feeding cylinder 102. A stirring mechanism for stirring the molten material is provided inside the molten feeding cylinder 102.

[0035] Working principle: In actual use, the molten material is fed into the rectangular forming cavity 103 through the feeding assembly. The gap between the leveling roller 205 and the first conveyor belt 206 corresponds to the thickness of the sheet material. When the formed sheet material comes out along the rectangular forming cavity 103, the leveling roller 205 matches the first conveyor belt 206, thereby performing a preliminary leveling operation on the sheet material. When the extrusion length reaches the set value, the cutting assembly completes the cutting of a single sheet material. The first motor 207 drives the first conveyor roller to rotate, and the second conveyor roller drives the first conveyor belt 206 to rotate, thereby sending the preliminary formed sheet material onto the unloaded second conveyor belt 304. Motor 305 drives the second transmission roller to rotate, thereby transferring the initially formed board to the center position. By rotating the motor group 300, the switching frame 302 is driven to rotate. The switching frame 302 will transfer the unloaded second transmission belt 304 to the downstream of the first leveling component to complete the material receiving. During the secondary leveling process, the flattening push rod 400 drives the flattening frame 401 and the flattening plate 403 to move downward, so that the flattening plate 403 presses down on the board on the second transmission belt 304, and cools and shapes the board to complete the final leveling process. The flattening plate 403 is equipped with a vibration motor to assist in the flattening process of the board.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
