Detailed Description

The present invention will be further described with reference to the accompanying drawings.

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and the following detailed description. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.

Referring to fig. 1-2, an extruder for producing a PE film comprises a machine barrel 1 and a driving motor 2, wherein an extrusion screw 3 is arranged in the machine barrel 1, a feed inlet 4 is formed in the upper end of the machine barrel 1, a supporting leg 5 is fixedly arranged at the lower end of the machine barrel 1, an extrusion head 6 is fixedly arranged at the output end of the machine barrel 1, a forming head 7 is fixedly arranged on the extrusion head 6, one end of the extrusion screw 3 penetrates through the machine barrel 1, a driven wheel 8 is fixedly arranged, a driving wheel 9 is fixedly arranged on an output shaft of the driving motor 2, a belt 10 is arranged between the driving wheel 9 and the driven wheel 8 for transmission connection, a mounting hole 11 is formed in the extrusion screw 3 along the main shaft direction of the extrusion. Extrusion screw 3 preferentially adopts the excellent material of heat conductivity, utilizes the transfer heat, can heat the material, prevents that the material from solidifying and causing the unable normal work of device in the barrel.

In this embodiment, the heating device 12 includes a heating wire 121 located in the mounting hole 11 and a power supply 122 located outside the mounting hole, and a movable connecting element 13 fixedly arranged outside the power supply 122 is rotatably connected with the main shaft of the extrusion screw 3. The power supply 122 is fixed to the barrel 1 by a connecting rod, preventing it from rotating.

In this embodiment, the movable connecting member 13 includes a connecting member 131 and a bearing 132, the bearing 132 is sleeved on the main shaft, the number of the connecting member 131 is at least two, one end of the connecting member is fixed on the power supply 122, and the other end of the connecting member is fixed on the bearing 132. The movable connecting piece 13 is used for preventing the heating device 12 from rotating along with the extrusion screw 3, and the using effect is influenced, specifically, when the extrusion screw 3 rotates, the bearing 132 rotates along with the extrusion screw 3 inside, and the bearing 132 does not rotate outside, so the power supply 122 connected with the connecting piece 131 also does not rotate, that is, the heating wire 121 also does not rotate, and thus the normal use of the heating device 12 is not influenced.

In this embodiment, the heating wire 121 is a spiral structure, and the heating area is increased, so that the extrusion screw 3 can be heated rapidly.

In this embodiment, driving motor 2 is gear motor, and the extrusion screw rod of being convenient for can adjust the rotational speed as required for material extrusion speed receives control.

The above description is only for the purpose of illustrating the technical solutions of the present invention and not for the purpose of limiting the same, and other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
