A PU tube raw material mixing device

Abstract

The utility model relates to a PU tube raw material mixing device, aiming to solve the problem that the existing PU tube raw material mixing device often uses a motor to drive a stirring shaft and a stirring rod to rotate to achieve mixing of the PU tube raw materials. Although the surface of the stirring shaft currently used is distributed with multiple layers of stirring rods, each layer of stirring rods can only stir in a fixed direction, so that the stirring range is still limited, resulting in insufficient stirring. The utility model comprises a tank body, the surface of the tank body is provided with a feed inlet, the top of the tank body is provided with a stirring mechanism, and the outer side of the stirring mechanism is provided with an auxiliary mechanism. The utility model effectively drives the driving gear to rotate through the operation of the stirring mechanism, thereby driving the driven gear meshing with the driving gear to rotate, and then driving the pinion and the limit rod to rotate. When the limit rod rotates, the spiral blades on its surface also rotate, thereby effectively driving the PU tube raw materials to flip up and down, increasing the stirring range and improving the mixing effect.

[0002] The production process of PU tubes mainly includes the steps of raw material preparation, batching, mixing, injection molding, molding and curing. During the mixing step, it is often necessary to use a mixing device to stir the raw materials so that the raw materials are fully mixed and evenly mixed to ensure the quality and performance of the PU tube.

[0003] Existing PU tube raw material mixing devices often use a motor to drive the stirring shaft and stirring rods to rotate to achieve mixing of the PU tube raw materials. Although the surface of the stirring shaft currently used is distributed with multiple layers of stirring rods, each layer of stirring rods can only stir in a fixed direction, so that the stirring range is still limited, resulting in insufficient stirring. In view of this, we propose a PU tube raw material mixing device. Utility Model Content

[0009] Preferably, the gear ring is connected to the brush holder through a fixing frame, and the brush side of the brush holder fits the inner wall of the tank body. The rotation of the brush holder facilitates the brush side to clean the inner wall of the tank body.

[0010] Preferably, the stirring mechanism comprises a motor, a movable end of the motor is connected to a stirring shaft, and a plurality of stirring rods are evenly distributed on the surface of the stirring shaft.

[0011] Preferably, the stirring shaft passes through the driving gear, and the stirring shaft and the driving gear are fixedly connected.

[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0023] A PU pipe raw material mixing device, see Figures 1 to 4 , comprising a tank body 1, a feed port 2 is provided on the surface of the tank body 1, a stirring mechanism 3 is provided on the top of the tank body 1, an auxiliary mechanism 4 is provided on the outside of the stirring mechanism 3, and a supporting frame 5 is attached to the outside of the auxiliary mechanism 4;

[0024] The auxiliary mechanism 4 includes a driving gear 401, and a plurality of driven gears 402 are matched and meshed on the outer side of the driving gear 401, and a pinion 403 is fixedly connected to the bottom of the driven gear 402. A limit rod 404 is passed through the inside of the driven gear 402 and the pinion 403, and a spiral blade 405 is provided on the outer surface of the limit rod 404, wherein the driven gear 402, the pinion 403 and the limit rod 404 are fixedly connected, and the spiral blades 405 are evenly distributed on the surface of the limit rod 404, and a gear ring 406 is matched and meshed on the outer side of the pinion 403. Further, the gear ring 406 is mounted inside the support frame 5, and the support frame 5 and the tank body 1 are fixedly connected. A group of fixing frames 407 are symmetrically arranged at the bottom of the gear ring 406, and a brush frame 408 is connected to the side of the fixing frame 407. Further, the gear ring 406 is connected to the brush frame 408 through the fixing frame 407, and the brush side of the brush frame 408 is in contact with the inner wall of the tank body 1. The utility model effectively drives the driving gear 401 to rotate through the operation of the stirring mechanism 3, thereby driving the driven gear 402 meshing with the driving gear 401 to rotate, and then driving the pinion 403 and the limiting rod 404 to rotate. When the limiting rod 404 rotates, the spiral blade 405 on its surface also rotates, thereby effectively driving the PU tube raw material to flip up and down, increasing the stirring range and improving the mixing effect. The rotation of the pinion 403 effectively drives the gear ring 406 to rotate, thereby causing the fixing frame 407 and the brush frame 408 at the bottom of the gear ring 406 to rotate, so that the brush frame 408 can clean the inner wall of the tank body 1.

[0025] It is worth noting that the stirring mechanism 3 includes a motor 301, and a stirring shaft 302 is connected to the movable end of the motor 301, wherein the stirring shaft 302 runs through the interior of the driving gear 401, the stirring shaft 302 and the driving gear 401 are fixedly connected, and a plurality of stirring rods 303 are evenly distributed on the surface of the stirring shaft 302. In the utility model, the motor 301 effectively drives the stirring shaft 302 to rotate, thereby driving the stirring rod 303 and the driving gear 401 to rotate, and the operation of the driving gear 401 can effectively drive the auxiliary mechanism 4 as a whole to perform auxiliary mixing, thereby improving the mixing efficiency.

[0026] Working principle: Pour the raw materials required for the PU tube into the tank body 1 from the feed port 2, and drive the stirring shaft 302 to rotate through the motor 301, thereby driving the stirring rod 303 and the driving gear 401 to rotate. The rotation of the driving gear 401 can drive the driven gear 402 meshing with the driving gear 401 to rotate, thereby driving the pinion 403 and the limiting rod 404 to rotate. When the limiting rod 404 rotates, the spiral blade 405 on its surface also rotates, thereby driving the PU tube raw materials to flip up and down, increasing the stirring range and improving the mixing effect. Since the rotation of the pinion 403 can drive the gear ring 406 to rotate, the fixing frame 407 and the brush frame 408 at the bottom of the gear ring 406 rotate, which is convenient for the brush frame 408 to clean the inner wall of the tank body 1.
