Abstract

The invention discloses a dual spiral heating wire drawing machine added with an underactuation stirring structure. The machine comprises a base, a motor, a coupler, an end cover, a radial bearing, afeeding opening, a hopper, the underactuation stirring structure, a machine cylinder, a support, a dual spiral heating screw rod, a screw rod screw groove, a wire drawing machine head, and a discharging opening. Multiple material inlet openings are formed, a raw material, a modifying agent and a coloring agent are directly and evenly mixed in the hopper, and production efficiency is improved; a dual spiral blade heating module is adopted, heating efficiency is improved, the temperature control precision is improved, and the problem that in the wire drawing process, a wire is prone to breakageis solved; the wire drawing machine sufficiently uses heat energy, and energy waste is reduced.

Description

technical field

[0001] The invention relates to the field of 3D printing consumables production, in particular to a double-helix heating wire drawing machine with an under-driven stirring structure. Background technique

[0002] All over the world, with the rapid development of 3D printing technology, the consumption of 3D printing consumables is increasing day by day. In my country, the demand for 3D printing consumables is rapidly increasing, and with the increase in consumption, energy consumption also increases accordingly. Existing plastic wire drawing machines need to mix plastic particles and modifiers in advance; the heating adopts the heating method of the heating module at the discharge port to produce wire drawing consumables; during the production process, it is found that this method has high energy consumption, low wire drawing accuracy, and inaccurate temperature control , The problem of complicated process. If vigorously promote 3D printing technology, this...

Embodiment Construction

[0020] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0021] The support 13 and the motor 2 are fixed on the base 1, the double-helix heating screw 12 starts to preheat to the set temperature, and then the stirring structure 10 is under-driven to rotate. The plastic powder enters the hopper 9 through the feed port 6 , the modifier passes through the feed port 7 , and the colorant enters the hopper 9 through the feed port 8 . The upper end of the under-driven stirring structure 10 is fixed in the hopper through the cover plate 1002 and the lower end through the sieve plate 1006. The motor 1001 of the under-driven stirring structure 10 drives the upper cross turntable 1003, the lower cross turntable 1004, and the diamond-shaped blade 1005 to mix powder, modifier, Colorant. After mixing evenly, it fa...
