Description

Technical Field

[0001] This utility model relates to the field of extruder technology, specifically to an extruder for an outer sheath of a thermal insulation pipe. Background Technology

[0002] Screw extruders rely on the pressure and shearing force generated by the rotating screw to fully plasticize and uniformly mix materials, which are then shaped through a die. To prevent material blockage in the hopper, modern screw extruders often incorporate an auger and a motor working in conjunction with it. Screw extruders also require motors, and some have multiple hoppers, leading to the use of multiple motors. Using multiple motors wastes motor resources, increases extruder costs, and provides a poor user experience. Utility Model Content

[0026] Please see Figures 1-5This application provides a technical solution: an extruder for an outer sheath of a thermal insulation pipe, including a frame 110, an extruder body 120, a support bracket 130, a motor 140, a U-shaped plate 150, a screw 160, a hopper 190, a second column 195, an auger 196, a transmission mechanism 170, and an anti-winding mechanism 180. The extruder body 120 is fixed to the frame 110 by the support bracket 130. The motor 140 and the U-shaped plate 150 are both fixed to the upper surface of the frame 110. The screw 160 is rotatably mounted on the extruder body 120. Several support brackets 130 are provided and are linearly and equidistantly installed on the upper surface of the frame 110. The several support brackets 130 make the extruder body 120 more firmly fixed to the frame 110.

[0027] One end of the screw 160 is fixed to the output shaft of the motor 140. The hopper 190 is installed on the housing of the extruder body 120. The lower end of the second column 195 is fixed to the upper end of the auger 196. The second column 195 is rotatably mounted on the hopper 190. The auger 196 is inserted into the hopper 190. The auger 196 and the screw 160 are correspondingly arranged. The hopper also includes a hopper cover 191, which is fixed to the hopper 190 by a hinge. The hopper cover 191 facilitates the injection of material into the hopper 190. The hopper also includes a latch 192, with different parts of the latch 192 fixed to the outer walls of the hopper 190 and the hopper cover 191. The latch 192 facilitates the opening and closing of the hopper cover 191. The hopper also includes a handle 193, which is fixed to the upper surface of the hopper cover 191. The handle 193 facilitates the opening and closing of the hopper cover 191. In this embodiment, the handle 193 is a lifting handle.

[0028] The transmission mechanism 170 is mounted on the U-shaped plate 150, the screw 160, and the second column 195. The transmission mechanism 170 enables the screw 160 and the auger 196 to rotate synchronously. The transmission mechanism 170 includes a first column 171, a gear transmission component 172, a first belt transmission component 173, and a second belt transmission component 174. The first column 171 is rotatably mounted on the U-shaped plate 150. There are two second columns 195. The first column 171 and one of the second columns 195 are connected together by the first belt transmission component 173. The first column 171 and the other second column 195 are connected together by the second belt transmission component 174. The first column 171 and the screw 160 are connected together by the gear transmission component 172.

[0029] Different anti-winding mechanisms 180 are respectively installed on one of the hoppers 190 and the U-shaped plate 150. The anti-winding mechanism 180 is set to prevent the belts on the first belt drive component 173 and the second belt drive component 174 from getting tangled together. The anti-winding mechanism 180 includes a support rod 181, a first partition 182, a second partition 183 and a third partition 184. The first partition 182 and the second partition 183 are both sleeved on the first column 171, and the third partition 184 is sleeved on one of the second columns 195. The first partition 182 and the second partition 183 are fixed to the U-shaped plate 150 by the support rod 181, and the third partition 184 is fixed to one of the hoppers 190 by different support rods 181.

[0030] The working principle and process of this utility model are as follows: In use, the motor 140 is started via the control box. The rotation of the output shaft of the motor 140 drives the screw 160 to rotate. The rotation of the screw 160 drives the gear transmission component 172 to rotate. The rotation of the gear transmission component 172 drives the first column 171 to rotate. The rotation of the first column 171 drives the first belt transmission component 173 and the second belt transmission component 174 to rotate. Under the action of the first belt transmission component 173 and the second belt transmission component 174, the two second columns 195 rotate synchronously. The rotation of the second columns 195 drives the auger 196 to rotate. The rotation of the auger 196 effectively prevents material from clogging in the hopper 190. When only one hopper 190 needs to be used, the belt on the first belt transmission component 173 or the second belt transmission component 174 corresponding to the hopper 190 not being used is removed. The first partition 182 and the second partition 194 are then removed. The first belt drive 173 and the second belt drive 174 are separated by the third partition 184, effectively preventing the belts from getting tangled. When other hoppers 190 need to be used, the belt is fitted onto the pulley on the second column 195, and then the belt is installed onto the pulley on the first column 171 using a pry bar. This allows for belt installation and removal without stopping the machine. The extruder for the outer sheath of the insulation pipe uses the gear drive 172, the first belt drive 173, and the second belt drive 174 to achieve synchronous rotation of the screw 160, the first column 171, and the two second columns 195, effectively preventing material from clogging in the hopper 190. In other words, one motor 140 can achieve synchronous rotation of the screw 160, the first column 171, and the two second columns 195, saving motor resources and equipment costs, and providing users with a better user experience.

[0031] The embodiments of this utility model have been described in detail above, but the content is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
