Description

Technical Field

[0001] This utility model relates to the field of resin cleaning technology, specifically a waste resin cleaning machine. Background Technology

[0002] In the production of wind turbine blades, hoses are used to transport resin raw materials. However, when production stops, the resin remaining inside the hoses gradually adheres to the hose walls and hardens, rendering the hoses unusable and ultimately requiring disposal as waste. Since these hoses are typically made of non-biodegradable plastic materials, traditional landfill disposal methods are not feasible. The usual practice is to crush the plastic pipes and recycle them.

[0003] However, before these hoses can be recycled, the hardened resin adhering to their inner walls must be thoroughly removed. But the hardened resin adhering to the inner walls of the hoses is not easy to clean, which is a problem that urgently needs to be solved. Utility Model Content

The cutting blade 432 is fixedly connected to a driven shaft 433 rotatably connected to the side wall of the dividing chamber 431.

[0032] The tube-breaking separation assembly 4 also includes a protective shell 44 located outside the first gear 414 and the second gear 416 and fixedly connected to the surface of the conveyor 411, and the motor 420 is fixedly connected to the protective shell 44.

[0033] The stirring and cleaning assembly 5 includes a stirring drum 501 whose upper end is fixedly connected to the dividing chamber 431. A stirring shaft 502 is rotatably connected inside the stirring drum 501. One end of the stirring shaft 502 passes through the end wall of the stirring drum 501 and is coaxially connected to the output shaft of the drive motor 503. The drive motor 503 is fixedly installed at the end of the stirring drum 501. A first pulley 504 is fixedly sleeved on the end of the stirring shaft 502 near the drive motor 503. The first pulley 504 is connected to a second pulley 506 fixedly connected to the driven shaft 433 via a transmission belt 505. It should be noted that a filling port is provided on the upper wall of the stirring drum 501, which can be used to add cleaning fluid into the stirring drum 501.

[0034] The outer wall of the mixing drum 501 is welded and fixed to the base 1 by a rigid fastener 6.

[0040] Working principle: When the motor 420 is started, the output shaft of the motor 420 drives the first gear 414 to rotate, which in turn drives the two sets of pressing conveyor rollers 413 to rotate. The plastic tube is clamped between the upper and lower symmetrical pressing conveyor rollers 413 and fed backward through the longitudinal groove 412. At the same time, the cutting roller 419 fixedly connected to the rotating shaft 415 will rotate through the synchronous pulley 417 and the synchronous belt 418. Because the cutting edge of the cutting wheel 419 is embedded in the center of the longitudinal groove 412 of the conveyor 411, the plastic tube is cut into two halves along the axial direction when it passes through. The rotating shafts 415 are staggered to ensure that the cutting wheel 419 can achieve full coverage cutting of the plastic tube. The axially cut plastic tube enters the dividing chamber 431. The cutting blade 432 rotates at high speed through the driven shaft 433 to cut the plastic tube into small segments laterally. The segmented plastic tube falls into the mixing drum 501. The drive motor 503 drives the mixing blade to rotate through the mixing shaft 502 to mix with the cleaning liquid and remove residual resin. After cleaning, the switch of the discharge nozzle 8 is turned on. The inclined discharge nozzle uses gravity to discharge the material and waste liquid.
