Obviously, what is described is only a part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 , the utility model provides two technical solutions:

[0021] Embodiment 1

[0022] A fusing and extruding device for producing plastic sheets comprises a workbench 1, a transmission mechanism 2 is arranged on both sides of the workbench 1, a lifting mechanism 3 is arranged in the middle position inside the workbench 1, a loading mechanism 4 is arranged at the top of the workbench 1, limiting mechanisms 5 are arranged at the tops of both sides of the workbench 1, and a fusing and extruding mechanism 6 is arranged in the middle position of the top of the workbench 1.

[0023] The transmission mechanism 2 includes transmission belts 201 installed on both sides of the top of the workbench 1 , and the transmission belts 201 can perform transmission work on the loading mechanism 4 .

[0024] The loading mechanism 4 includes a loading frame 401 arranged on one side of the top of the conveyor belt 201, and a movable plate 402 is slidably connected to the bottom end of the loading frame 401. Slots 403 are arranged in the middle positions of both sides of the loading mechanism 4, and a guide groove 404 is arranged on one side of the outside of the loading mechanism 4. Plastic raw materials can be placed in the loading mechanism 4. When the guide groove 404 on one side of the loading mechanism 4 contacts with the plug block 504, the plug block 504 can be pushed to move. When the plug block 504 is inserted into the slot 403 on the loading mechanism 4, the position of the loading mechanism 4 can be fixed.

[0025] The limiting mechanism 5 includes a pull rod 501 slidably connected to the top ends of both sides of the workbench 1, a movable block 502 is fixedly connected to one side of the pull rod 501, a spring 503 is fixedly connected to one side of the movable block 502, and an insert block 504 that is externally plugged into the slot 403 is fixedly connected to the side of the movable block 502 away from the spring 503. When the insert block 504 is subjected to force, the spring 503 can be squeezed by the movable block 502. At this time, the insert block 504 can be retracted into the interior of the workbench 1. When the force on the insert block 504 is removed, the movable block 502 can push the insert block 504 out of the interior of the workbench 1 due to the reaction force of the squeezing of the spring 503.

[0026] The fusing and extruding mechanism 6 includes a fixed frame 601 fixedly connected to the middle position of the top of the workbench 1, a hydraulic rod 602 is installed in the middle position of the top of the fixed frame 601, and a hot pressing plate 7 is installed at the bottom end of the hydraulic rod 602. When the hydraulic rod 602 is started, the hot pressing plate 7 can be pushed downward, and the hot pressing plate 7 can heat and fuse the plastic raw materials in the loading mechanism 4 and then extrude them into shape.

[0027] Embodiment 2

[0028] The main difference from the first embodiment is:

[0029] A fusing and extruding device for producing plastic sheets, wherein a lifting mechanism 3 includes a servo motor 301 installed at the middle position of the bottom end of a workbench 1, a threaded rod 302 is installed at the output shaft end of the servo motor 301, and a threaded barrel 303 is connected to the external thread of the threaded rod 302. The bottom ends of both sides of the threaded barrel 303 are fixedly connected to limit blocks 304, and the top of the threaded barrel 303 is fixedly connected to a push plate 305. When the servo motor 301 is started, the threaded rod 302 can be driven to rotate inside the threaded barrel 303. At this time, the threaded barrel 303 can push the push plate 305 to perform lifting movements, and the push plate 305 pushes the movable plate 402 at the bottom end of the loading mechanism 4 to lift, so that the movable plate 402 can push the plastic sheet after fusing and extrusion in the loading mechanism 4 to lift. At the same time, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0030] When the embodiment of the present application is in use: the material loading mechanism 4 loaded with plastic raw materials is placed on the top of the conveyor belt 201 on the left side of the workbench 1. At this time, the conveyor belt 201 is started to push the material loading mechanism 4 to move. When the guide groove 404 on one side of the material loading mechanism 4 contacts the plug blocks 504 on both sides of the workbench 1, the guide groove 404 can push the plug blocks 504. At this time, the plug blocks 504 can squeeze the springs 503 through the movable blocks 502. At this time, the plug blocks 504 can be put into the workbench 1. When the material loading mechanism 4 moves to the middle position inside the workbench 1, the plug blocks 504 are no longer stressed, and due to the reverse action of the springs 503 being squeezed, the material loading mechanism 4 is pushed back. By applying force, the insert block 504 can be pushed into the slot 403 on the loading mechanism 4 through the movable block 502. At this time, the conveyor belt 201 is closed and started by the hydraulic rod 602, which can push the hot pressing plate 7 to move downward. The hot pressing plate 7 can heat and fuse the plastic raw materials in the loading mechanism 4, and press the hot pressing plate 7 downward to extrude the plastic raw materials. After the processing is completed, by pulling the pull rod 501, the pull rod 501 can drive the insert block 504 to be pulled out of the slot 403 on the loading mechanism 4 through the movable block 502. At this time, the conveyor belt 201 is started to push the loading mechanism 4 and the internal plastic sheets to quickly discharge the materials.
