[0027] like Figures 1 to 6 As shown, the utility model provides an extruder for producing waterproof membranes, including a bottom plate 1, with limiting grooves 2 provided on both the front and rear sides of the upper surface of the bottom plate 1, and movable plates 3 movably connected to the inner surface of the limiting grooves 2.

A motor 10 is fixedly installed on the lower side of the left surface of the mounting plate 6. The other end of the output shaft of motor No. 1 10 is fixedly sleeved with a screw 11, and the right end of the screw 11 sequentially penetrates the mounting plate 6 and the fixed plate 7 and extends to the right side of the fixed plate 7. The outer surface of the fixed plate 7 is threadedly sleeved with a driving plate 9, and the inner surfaces of the front and rear sides of the driving plate 9 are movably connected to the outer surface of the cylinder 5. The left surface of the mounting plate 6 is fixedly connected to a limiting rod 8 located on the rear side of the screw 11, and the right end of the limiting rod 8 sequentially penetrates the mounting plate 6, the driving plate 9 and the fixed plate 7 and extends to the right side of the fixed plate 7. The outer surface of the limiting rod 8 is movably sleeved with the inner surface of the driving plate 9.

[0028] The operation of motor No. 1 10 will cause the screw 11 to start rotating, and the rotation of the screw 11 will drive the driving plate 9, causing the driving plate 9 to start moving to the left, and the movement of the driving plate 9 will drive the cylinder 5, causing the two movable plates 3 to start moving along the inner surface of the limit groove 2 as a whole.

[0029] Among them, the front end of the inner surface of the limiting groove 2 is fixedly connected with a fixing rod 12, and the rear end of the fixing rod 12 passes through the movable plate 3 and the bottom plate 1 in sequence and extends to the rear side of the inner surface of the limiting groove 2, and the outer surface of the fixing rod 12 and the inner surface of the movable plate 3 are movably connected.

[0030] The design of the fixing rod 12 ensures the stability of the overall movement of the two movable panels 3.

[0031] Among them, the top ends of the two movable plates 3 are fixedly connected with a mounting sleeve 13, the inner surface of the mounting sleeve 13 is fixedly connected with an extrusion cylinder 14, the right side of the outer surface of the extrusion cylinder 14 is fixedly connected with a heating plate 16 located inside the mounting sleeve 13, and the outer surface of the heating plate 16 is fixedly connected to the inner surface of the mounting sleeve 13.

[0032] The operation of the heating plate 16 can heat the materials inside the extrusion barrel 14, thereby causing the materials to melt and begin to mix with each other.

[0033] Among them, a discharge plate 15 is fixedly connected to the left side of the upper surface of the mounting sleeve 13. There are two discharge plates 15. The bottom ends of the two discharge plates 15 pass through the mounting sleeve 13 and the extrusion cylinder 14 in sequence and extend to the inner surface of the extrusion cylinder 14.

[0034] When the two discharge plates 15 are closed together, the operator can put the material into the interior of the extrusion cylinder 14 through the discharge plates 15 .

[0035] Among them, the inner surface of the top of the mounting plate 6 is fixedly mounted with the No. 2 motor 17, and the other end of the output shaft of the No. 2 motor 17 is fixedly sleeved with the No. 2 circular shaft 18. The right end of the No. 2 circular shaft 18 passes through the mounting sleeve 13 and the extrusion cylinder 14 in sequence and extends to the interior of the extrusion cylinder 14.

[0036] The operation of the second motor 17 will cause the second circular shaft 18 to start rotating as a whole.

[0037] Among them, the inner surface of the extrusion cylinder 14 is movably connected to a spiral plate 19, the inner surface of the spiral plate 19 is fixedly connected to the outer surface of the second circular shaft 18, and the inner surface of the extrusion cylinder 14 is movably connected to a die 20 located on the right side of the spiral plate 19.

[0038] The rotation of the spiral plate 19 can mix and transport the melted material inside the extrusion cylinder 14 .

[0039] The left side of the inner surface of the die 20 is fixedly connected to a stirring rod 21 , and the outer surface of the die 20 is fixedly sleeved with a driven gear 22 located on the right side of the extrusion cylinder 14 .

[0040] When the die 20 starts to rotate as a whole, the stirring rod 21 stirs the melted material, thereby improving the mixing degree between different materials inside the extrusion barrel 14.

[0041] Among them, a No. 3 motor 23 is fixedly installed on the right side of the upper surface of the base plate 1, and a No. 3 circular shaft 24 is fixedly sleeved on the other end of the output shaft of the No. 3 motor 23.

[0042] The operation of the third motor 23 will cause the third circular shaft 24 to start rotating as a whole.

[0043] The outer surface of the third circular shaft 24 is fixedly sleeved with a driving gear 25 , and the outer surface of the driving gear 25 is meshed with the outer surface of the driven gear 22 .

[0046] The design of the fixing seat 26 and the limiting sleeve 27 prevents the die 20 from falling as a whole.

[0047] The working principle and use process of this utility model:

[0048] When the operator needs to clean and maintain the spiral plate 19, the operator starts the No. 1 motor 10. As the No. 1 motor 10 runs, the screw 11 will start to rotate and drive the driving plate 9, so that the driving plate 9 starts to move to the left along the outer surface of the limit rod 8. During this process, since the inner surface of the driving plate 9 and the cylinder 5 are in contact with each other, the movement of the driving plate 9 will drive the cylinder 5, so that the two cylinders 5 and the two movable plates 3 as a whole begin to move away from each other along the inner surface of the limit groove 2. Finally, the spiral plate 19 will be exposed from the inside of the mounting sleeve 13 due to the overall movement of the two movable plates 3, thereby facilitating the cleaning and maintenance of the spiral plate 19.

[0049] When the operator starts to produce the waterproof membrane, the operator first puts several raw materials into the interior of the extruder 14 through the discharge plate 15, and then starts the heating plate 16, the second motor 17 and the third motor 23. The operation of the heating plate 16 will start to heat the extruder 14 and the materials inside the extruder 14 so that the raw materials begin to melt. The operation of the second motor 17 will cause the second circular shaft 18 and the spiral plate 19 to start rotating to mix and transport the raw materials, and the operation of the third motor 23 will cause the third circular shaft 24 and the driving gear 25 to start rotating. At this time, the driven gear 22 and the die 20 as a whole will start to rotate under the drive of the driving gear 25. During this process, the stirring rod 21 will mix and stir the materials inside the extruder 14. Finally, under the joint action of the extruder 14, the heating plate 16, the spiral plate 19, the die 20 and the stirring rod 21, the mixed material will be extruded from the right end of the die 20.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
