[0007] Preferably, an air inlet pipe is connected to the side wall of the feeding hopper; the air inlet pipe is arranged at a position corresponding to the feeding hopper close to the feeding pipe; so that when the plastic particles enter the extruder body and the feeding pipe, the plastic particles are heated more fully, thereby achieving a better heating effect on the plastic particles.

[0008] Preferably, a baffle plate is fixedly connected to the inside of the feeding hopper; a plurality of feed holes are opened inside the baffle plate; a plurality of push plates are fixedly connected to the side wall of the rotating shaft, and the push plates are regularly arranged in a circular array on the side wall of the rotating shaft; the bottom of the push plate contacts the top of the baffle plate; this can effectively prevent the plastic particles from accumulating at the same place inside the feeding hopper, so that the plastic particles are better heated by the hot air entering from the air inlet pipe.

[0009] Preferably, a pushing auger is fixedly connected to the side wall of the rotating shaft; the pushing auger is arranged at a position corresponding to the bottom of the feeding hopper; and bubbles can be effectively prevented from appearing inside the plastic particles after the plastic particles are melted inside the extruder body.

[0028] like Figure 2 and Figure 4 As shown, an air inlet pipe 14 is connected to the side wall of the feeding hopper 4; the air inlet pipe 14 is arranged at a position corresponding to the feeding hopper 4 close to the feeding pipe 3; during operation, when plastic particles are put into the feeding hopper 4, hot air can be introduced into the feeding hopper 4 through the air inlet pipe 14 to heat the plastic particles in the feeding hopper 4, thereby preheating the plastic particles, so that when the plastic particles enter the extruder body 2 and the feeding pipe 3, the heating of the plastic particles is more sufficient, thereby achieving a better heating effect on the plastic particles.

[0029] like Figure 2As shown, a blocking plate 10 is fixedly connected to the inside of the feeding hopper 4; a plurality of feed holes 11 are opened inside the blocking plate 10; a plurality of push plates 12 are fixedly connected to the side wall of the rotating shaft 9, and the push plates 12 are regularly arranged in a circular array on the side wall of the rotating shaft 9; the bottom of the push plate 12 contacts the top of the blocking plate 10; during operation, when it is necessary to put plastic particles into the inside of the feeding hopper 4, the plastic particles can be blocked by the blocking plate 10, and at the same time, the push plate 12 is driven to rotate by the rotating shaft 9 to push the plastic particles on the top of the blocking plate 10, so that the plastic particles can enter the inside of the feeding hopper 4 through the plurality of feed holes 11, thereby effectively avoiding the accumulation of plastic particles at the same place inside the feeding hopper 4, so that the plastic particles are better heated by the hot air entering the air inlet pipe 14.

[0030] like Figure 3 and Figure 6 As shown, a pushing auger 15 is fixedly connected to the side wall of the rotating shaft 9; the pushing auger 15 is arranged at a position corresponding to the bottom of the feeding hopper 4; when working, when the plastic particles are stirred by the stirring blades 901, the plastic particles are pushed by the pushing auger 15, which can stir the plastic particles and make the plastic particles enter the interior of the feeding pipe 3 better, thereby effectively avoiding the occurrence of bubbles inside the plastic particles after the plastic particles are melted inside the extruder body 2.

[0031] like Figure 3 and Figure 5 As shown, the interior of the fixing bolt 13 is slidably connected with a sliding plate 16; a spring is fixedly connected between the top of the sliding plate 16 and the inner side wall of the fixing bolt 13; a connecting rod 17 is fixedly connected to the bottom of the sliding plate 16; and a contact block 18 is fixedly connected to the bottom end of the connecting rod 17; during operation, when the feeding hopper 4 is fixed by the fixing bolt 13, the sliding plate 16 is pushed by the spring, so that the connecting rod 17 and the contact block 18 push the bottom of the threaded hole, thereby making the pressure between the fixing bolt 13 and the threaded hole greater, making the friction between the fixing bolt 13 and the threaded hole greater, so that the fixing effect of the fixing bolt 13 on the feeding hopper 4 can be better.

[0032] like Figure 4 As shown, a material blocking net 19 is fixedly connected to the interior of the air inlet pipe 14; the material blocking net 19 is arranged at one end of the air inlet pipe 14 close to the interior of the feeding hopper 4; during operation, when the plastic particles inside the feeding hopper 4 are preheated through the air inlet pipe 14, the material blocking net 19 is arranged at the end of the air inlet pipe 14 to block the plastic particles, thereby effectively preventing the plastic particles from entering the interior of the air inlet pipe 14.

[0033] like Figure 6As shown, a positioning block 20 is fixedly connected to the side wall of the rotating shaft 9; the positioning block 20 is rotatably connected to the internal position of the blocking plate 10; during operation, when the rotating shaft 9 rotates inside the blocking plate 10, the blocking plate 10 limits the rotation of the positioning block 20, so that the blocking plate 10 is less likely to tilt during rotation, making the rotation of the blocking plate 10 more stable.

[0034] like Figure 6 As shown, a plurality of anti-wear balls 21 are arranged between the blocking plate 10 and the positioning block 20; the side walls of the anti-wear balls 21 are in contact with the side walls of the blocking plate 10 and the positioning block 20; during operation, when the positioning block 20 rotates inside the blocking plate 10, by arranging the anti-wear balls 21 between the blocking plate 10 and the positioning block 20, the sliding friction between the blocking plate 10 and the positioning block 20 can be converted into rolling friction, so that the friction force between the blocking plate 10 and the positioning block 20 is smaller, thereby reducing the wear between the blocking plate 10 and the positioning block 20.

[0035] During operation, when the extruder body 2 needs to be fed, the plastic particles can be placed in the internal position of the feeding hopper 4, and then the mounting frame 6 can be driven to rotate by the driving motor 8, so that the mounting frame 6 drives the stirring blades 901 to rotate, and then the plastic particles can be stirred by the stirring blades 901, thereby effectively avoiding the blockage and bridging of the plastic particles inside the feeding hopper 4, so that the feeding effect of the extruder body 2 is better.

[0036] When plastic particles are put into the feeding hopper 4, hot air can be introduced into the feeding hopper 4 through the air inlet pipe 14 to heat the plastic particles in the feeding hopper 4, thereby preheating the plastic particles, so that when the plastic particles enter the extruder body 2 and the feeding pipe 3, the heating of the plastic particles is more sufficient, thereby achieving a better heating effect on the plastic particles.

[0038] When the plastic particles are stirred by the stirring blades 901, the auger 15 is pushed to push the plastic particles, so that the plastic particles can be stirred and at the same time, the plastic particles can be better allowed to enter the interior of the feed pipe 3, thereby effectively preventing the formation of bubbles inside the plastic particles after the plastic particles are melted inside the extruder body 2.

[0039] When the feeding hopper 4 is fixed by the fixing bolt 13, the sliding plate 16 is pushed by the spring, so that the connecting rod 17 and the contact block 18 push the bottom of the threaded hole, thereby making the pressure between the fixing bolt 13 and the threaded hole greater, and making the friction between the fixing bolt 13 and the threaded hole greater, so that the fixing effect of the fixing bolt 13 on the feeding hopper 4 can be better.

[0040] When the plastic particles in the feeding hopper 4 are preheated through the air inlet pipe 14 , the plastic particles can be blocked by providing a material blocking net 19 at the end of the air inlet pipe 14 , thereby effectively preventing the plastic particles from entering the air inlet pipe 14 .

[0041] When the rotating shaft 9 rotates inside the blocking plate 10 , the blocking plate 10 limits the rotation of the positioning block 20 , so that the blocking plate 10 is less likely to tilt during rotation, and the rotation of the blocking plate 10 is more stable.

[0042] When the positioning block 20 rotates inside the blocking plate 10, by arranging the anti-wear ball 21 between the blocking plate 10 and the positioning block 20, the sliding friction between the blocking plate 10 and the positioning block 20 can be changed into rolling friction, so that the friction force between the blocking plate 10 and the positioning block 20 is smaller, thereby reducing the wear between the blocking plate 10 and the positioning block 20.
