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.

[0024] Example 1

[0025] Please see Figures 1-3 A composite modified plastic extruder includes a hopper 1, an output pipe 2 fixedly installed on the lower surface of the hopper 1, an mounting plate 3 fixedly installed on the outer surface of the hopper 1, three first connecting plates 4 fixedly connected to the outer surface of the mounting plate 3, a sleeve 5 provided on the lower surface of the hopper 1, three second connecting plates 6 fixedly connected to the outer surface of the sleeve 5, bolts 7 rotatably provided on the lower surface of each of the three second connecting plates 6, nuts 8 rotatably provided on the outer surface of the bolts 7, a plurality of die heads 9 slidably provided on the inner surface of the sleeve 5, and a clamping plate 10 fixedly connected to the upper surface of the plurality of die heads 9.

[0026] Specifically, through the cooperation between hopper 1, output pipe 2, mounting plate 3, first connecting plate 4, sleeve 5, second connecting plate 6, bolt 7, nut 8, mold head 9, and clamping plate 10, the mold head 9 and hopper 1 can be easily disassembled and installed. This facilitates cleaning and allows for the replacement of different mold heads 9 to meet molding requirements.

[0027] In this implementation scheme: the output pipe 2 is set in a corresponding manner to the mold head 9, and the upper surfaces of the first connecting plate 4 and the second connecting plate 6 are both provided with threaded grooves that are threadedly connected to the bolt 7.

[0028] Specifically, the first connecting plate 4 and the second connecting plate 6 are attached together, and the first connecting plate 4 and the second connecting plate 6 are limited and fixed by bolts 7 with threaded grooves.

[0029] In this embodiment: a collar is fixedly connected to the inner surface of the sleeve 5, and the clamping plate 10 is correspondingly clamped to the collar.

[0030] Specifically, the die head 9 is secured inside the sleeve 5 by a clamping plate 10 and a collar.

[0031] Working principle: The material output from the hopper 1 of the composite modified plastic extruder enters the die head 9 through the output pipe 2 for output molding. The die head 9 can be replaced as needed. The bolt 7 and nut 8 are disengaged from the threaded grooves on the first connecting plate 4 and the second connecting plate 6. The sleeve 5 is removed from the hopper 1. Then, the retaining plate 10 on the die head 9 is disengaged from the collar, and other die heads 9 can be replaced. The retaining plate 10 on the die head 9 is placed into the sleeve 5 and engaged with the collar. The second connecting plate 6 and the first connecting plate 4 are fitted together. Then, the bolt 7 is rotated and connected to the threaded groove. The other end is fixed by the nut 8 to ensure the stability of the installation.

[0032] Example 2

[0033] Please see Figure 1 , Figure 4 Based on Embodiment 1, this utility model provides a technical solution:

[0034] In this embodiment: an insulation ring 11 is fixedly wrapped around the outer surface of the hopper 1, a heating ring 12 is fixedly installed on the outer surface of the hopper 1, and an electric heating wire 13 is fixedly installed on the inner surface of the heating ring 12.

[0035] Specifically, through the cooperation of the insulation ring 11, the heating ring 12, and the heating wire 13, the material conveyed in the hopper 1 can be kept warm in real time to ensure that the material can be stably output and molded.

[0036] In this implementation scheme: the insulation ring 11 is made of rubber and plastic insulation material, and the heating wire 13 is set in a corresponding manner with the hopper 1.

[0037] Specifically, the rubber and plastic insulation material of insulation ring 11 has a low thermal conductivity and a high closed-cell rate, which effectively blocks heat transfer.

[0038] Working principle: When the hopper 1 is conveying materials, the heating wire 13 in the heating coil 12 is turned on to maintain a constant temperature output in the hopper 1. The heat insulation coil 11 prevents the heat from dissipating from the hopper 1.
