However, since the pulling rope lifts one end of the loading shell, there is no limiting structure on the other end of the loading shell, which causes the other end of the loading shell to tilt when it rises to the feed hopper position, thereby reducing the loading effect of the loading shell and making the material loading unstable. Therefore, we need to propose an extruder for producing waterproof membranes. Utility Model Content

[0024] The material turning mechanism 5 includes a fixed plate 51 fixedly connected to one side of the lifting platform 45, and connecting plates 52 are welded at both ends of one side of the fixed plate 51, and one end of the opposite side of the connecting plate 52 is rotatably connected to a mounting seat 53, and an electric push rod 55 is provided on one side of the mounting seat 53, and a hinge block 56 is fixedly connected to the telescopic rod end of the electric push rod 55, and the hinge block is rotatably connected to the hinge seat 15.

[0025] A forward and reverse motor 12 is fixedly connected to the lower surface of the base 1. The lower end of the screw 43 passes through the base 1 and is driven by the forward and reverse motor 12. A limit switch 11 is set at the top of the guide groove 42. The limit switch 11 limits the position of the lifting platform 45 to prevent the lifting platform 45 from hitting the top of the guide groove 42. The limit switch 11 is convenient for transmitting signals to the controller 7. The controller 7 controls the forward and reverse motor 12 to stop and the two sets of electric push rods 55 to start, thereby improving the efficiency of material feeding.

[0026] Multiple groups of steel balls 47 are embedded on both sides adjacent to the lifting platform 45 and the fixed plate 51, and the multiple groups of steel balls 47 are arranged at equal intervals. Limiting grooves 44 for the steel balls 47 to roll and connect are provided on both sides of the guide groove 42. The steel balls 47 roll with the limiting grooves 44 on both sides of the guide groove 42, thereby improving the stability of the lifting platform 45 during lifting and lowering, thereby improving the stability of the upper hopper 8.

[0027] The two groups of connecting plates 52 are both arranged vertically to the fixed plate 51, and the two groups of mounting seats 53 are fixedly connected to the adjacent side of the electric push rod 55 with a fixing pin 54, and the fixing pin 54 is inserted into one side of the connecting plate 52, and the mounting seat 53 and the connecting plate 52 are rotatably connected through the fixing pin 54, so that when the telescopic rod of the electric push rod 55 is extended, the angle of the electric push rod 55 and the horizontal plane changes, thereby facilitating the flipping of the upper hopper 8.

[0028] A drainage plate 13 is fixedly connected to one end of the upper surface of the upper hopper 8, and a feed channel 3 is connected to the upper end of one side of the extruder body 2. The drainage plate 13 facilitates the drainage of materials in the overturned upper hopper 8 into the feed channel 3, thereby feeding the extruder body 2 and improving the extrusion efficiency of the waterproof material production.

The length of the fixing plate 51 is greater than the width of the column 41. The universal wheels 10 facilitate movement of the device, thereby improving convenience.

[0031] When in use, the staff pours the material of the waterproof membrane into the upper hopper 8, and sends instructions to the controller 7 through the control panel 9, so that the controller 7 controls the forward and reverse motor 12 to start, and the transmission screw 43 of the forward and reverse motor 12 drives the lifting platform 45 to rise along the guide groove 42 on the column 41, and the steel ball 47 rolls with the limit groove 44, which improves the stability of the lifting platform 45 when it is lifted. When the lifting platform 45 rises to the top of the guide groove 42, it hits the limit switch 11, and the limit switch 11 sends an instruction to the controller 7. The controller 7 controls the forward and reverse motor 12 to stop and controls the two sets of electric push rods 55 to extend the telescopic rods, so that the upper hopper 8 is turned over with the joint position of the joint plate 14 and the side plate 46, so that the material in the upper hopper 8 falls into the feeding channel 3 through the guide plate 13, completing the loading of the waterproof material, improving the stability of the lifting and lowering of the upper hopper 8, avoiding the shaking of the upper hopper 8 when loading, and thus improving the production efficiency of the waterproof membrane.
