As shown in fig. 1 to 3, the degradable pet bag extruder comprises a base 1, wherein a driving device 2, a speed reducing device 3, a transmission device 4 and an insulation can 6 are arranged on the base 1. The output shaft of the driving device 2 is connected with the input shaft of the speed reducing device 3, and the output shaft of the speed reducing device 3 is connected with the input shaft of the transmission device 4.

The insulation can 6 is internally provided with a charging barrel 8, an electric heating device 7 and a translation device 12. An extrusion screw 9 is rotatably arranged in the charging barrel 8, and one end of the screw 9 is connected with an output shaft of the transmission device 4. The outlet of the barrel 8 is connected in turn with a filter device 10, a mixing box 16 and an extrusion head 17, the inlet of which is connected with the feed hopper 5.

The electric heating devices 7 are multiple in number and are sequentially arranged at equal intervals on the outer side of the charging barrel 8, and the translation devices 12 drive the electric heating devices 7 to move at equal intervals along the axial direction of the charging barrel 8. The electric heating device 7 is heated after being electrified, and heats the charging barrel 8 through radiation, so that the temperature of the raw material in the charging barrel 8 is raised.

When the temperature of the raw material at the position of the charging barrel 8 close to the outlet does not reach the set value, the translation device 12 is started to quickly concentrate all the electric heating devices 8 to the position, so that the local temperature is increased to realize the purpose of quick temperature rise. The temperature of the electric heating device 8 does not change in this process, so that the electric power consumption is not additionally increased. After the temperature of the raw material reaches the set value, the translation device 12 disperses the electric heating device 8 gradually, and the temperature of the electric heating device is also increased slowly to heat the raw material in the whole charging barrel 8.

Preferably, the mixing box 16 has a mounting cylinder 23, a pressure gauge 14 and a temperature gauge 15, a piston 19 is arranged in the mounting cylinder 23 in a movable and sealed manner, a linear motor 18 for driving the piston 19 to move axially is arranged at the end of the piston, and a heating rod 20 capable of being inserted into or withdrawn from the mixing box 16 is arranged at the bottom of the piston 19.

When the pressure gauge 14 and the temperature gauge 15 detect that the material in the mixing box 16 does not reach the set requirement, the linear motor 18 is started, and the piston 19 is driven to insert the heating rod 20 into the mixing box 16 to heat the material inside again. When the material does not need to be heated, the heating rod 20 exits the mixing box.

As a preferred example, the filter device 10 has a plurality of filter channels 22 communicating the cartridge 8 and the mixing box 16, the filter channels 22 having a lower density of holes on the inlet side of the filter device 10 than on the outlet side.

Since the holes on the outlet side are more dense, the raw material undergoes one extrusion while passing through the filtering passage 22, thereby providing an advantageous condition for the final extrusion.

As a preferred example, the electric heating device 7 is a heating ring, and the heating ring is sleeved on the outer periphery of the charging barrel 8. The electric heating device 7 with a circular structure can be matched with the shape of the charging barrel 8 so as to uniformly heat in the circumferential direction.

Preferably, the translation device 12 includes a plurality of X-arms 24 and electric push rods 21, the X-arms 24 are hinged to each other along a straight line, one end of the X-arm 24 at the end is fixed, the other end is hinged to the push rod of the electric push rod 21, and the electric push rod 21 is hinged. The X-arm 24 changes in length as it rotates about the central hinge axis, thereby achieving overall telescoping.

Preferably, the bottom of the translation device 12 is further provided with a linear slide 13, and the linear slide 13 is fixedly arranged along the axial direction of the charging barrel 8. The linear slide rail 12 provides stability and smoothness for extension and retraction of the translation device 12.

Preferably, a screw feeder 25 is further provided in the hopper 5. The screw feeder 25 has a conical screw which is adapted to the conical structure of the feed hopper 5 in order to better feed the material into the barrel 8.
