Description

Technical Field

[0001] The utility model relates to the technical field of powder processing machinery, in particular to a stirring device and a feeder. Background Art

[0002] Many industries require powders, such as foam board production and chemical production. Powders are mixed according to the formula in feeders and then transported to subsequent production and processing units. The uniformity and efficiency of the powder mix will affect production and processing efficiency.

[0003] The screw feeders currently used in extruders (typically single-screw or twin-screw feeders) consist of a hopper and a feeder. While the feeder has a spiral agitator, the hopper itself lacks a stirring mechanism. This can lead to material becoming lodged in the hopper, leaving no material between the hopper and the spiral structure. This can cause material to become stuck in the feeder hopper, potentially damaging the feeder.

[0004] If the hopper is overhead and the material suddenly scatters and falls down (the upper hopper will also have an impact on the feeder when it is automatically replenished), it will impact the feeder, causing the feeder to suddenly increase the feeding amount, resulting in unstable discharge, poor control of product thickness, and inability to produce normally. Utility Model Content

[0054] The terms "first" and "second" are used for descriptive purposes only and are not intended to imply relative importance.

[0055] Some embodiments of the present invention provide a stirring device, the structure of which is as follows: Figures 1 to 6 .

[0056] The cylinder 1 forms a cylinder cavity. Several first stirring rods 2 are spaced apart along the cylinder's axial direction within the cylinder cavity. In this embodiment, the cylinder 1 is cylindrical, having a columnar outer wall and two end panels. The first stirring rods 2 are mounted on at least one end panel. When the stirring device is in operation, the first stirring rods 2 are stationary.

[0057] The rotating shaft 3 is inserted into the cylinder, partially located inside the cylinder cavity and partially located outside the cylinder cavity. A power assembly is connected to the rotating shaft and can drive the rotating shaft to rotate. Specifically, the power assembly can be a speed reducer 4, and the power output shaft of the speed reducer is connected to the portion of the rotating shaft 3 located outside the cylinder cavity.

[0058] The turntable 5 is mounted on the rotating shaft 3 . A plurality of second stirring rods 6 are arranged at intervals on the turntable 5 . The second stirring rods 5 are inserted into the gaps between the first stirring rods 2 .

[0059] The first stirring rod 2 and the second stirring rod 6 are both of a certain length, and there is an overlap between the two stirring rods in the direction of their extension. After the speed reducer 4 is activated, it drives the rotating shaft 3 to rotate. When the material passes through the gap between the two stirring rods, the material is agitated and thoroughly mixed.

[0060] In some embodiments of the present invention, a structural structure of a cylinder and an installation form of the first stirring rod 2 are further provided.

[0061] The main body of the cylinder is open at both ends; it is provided with a feed port 10 and a discharge port 11. The feed port 10 is used to admit the materials to be mixed, and the discharge port is used to discharge the mixed and stirred materials. In this embodiment, the feed port 10 and the discharge port 11 are respectively designed at the two ends of the cylinder body in the axial direction, with the feed port 10 located radially above and the discharge port 11 located radially below.

[0062] The first side end cap 7 is mounted on the first side opening end of the body and is detachable from the body. The second side end cap 8 is mounted on the second side opening end of the body and is detachable from the body. Both end caps can be bolted together to form a detachable structure. To facilitate assembly and disassembly, handles can be optionally provided on each end cap. In this embodiment, a handle 9 is provided on the second side end cap 8.

[0063] The first stirring rod 2 is arranged on the first side end cover 7 and / or the second side end cover 8. The first side end cover 7, the second side end cover 8 and the main body surround the cylindrical cavity.

[0064] The barrel body can be designed as a cylindrical body, and both end caps are circular. In the use state, the axial direction of the barrel body 1 is set along the direction parallel to the ground. In a preferred embodiment, a first stirring rod 2 can be set on both end caps to improve the stirring effect.

[0065] In some embodiments of the present invention, the first side end cap 7 is provided with an axial hole, through which the rotating shaft 3 is inserted into the barrel cavity. Since the axial hole is provided in the first side end cap 7, a handle is not provided. The rotating shaft 3 can also be inserted from the side of the second side end cap 8, and the handle is correspondingly designed on the side of the first side end cap 7.

[0066] In some embodiments of the present invention, a first stirring rod 2 is provided on the upper edge of the first side end cover 7 in a direction toward the second side end cover 8, and a first stirring rod 2 is provided on the upper edge of the second side end cover 8 in a direction toward the first side end cover 7. There is a gap between the opposite ends of the first stirring rods 2 on the two end covers, that is, the length of the cylinder body is greater than the sum of the lengths of the first stirring rods 2 on the two end covers, and the turntable 5 is located in the gap, so as to avoid motion interference with the first stirring rods 2 on both sides.

[0067] Since there are first stirring rods 2 on both sides of the turntable 5, in order to improve the stirring effect, in some embodiments of the present invention, second stirring rods 6 are provided on both sides of the turntable 5, and the second stirring rod 2 on the side of the turntable facing the first side end cover 7 is set with a gap from the first stirring rod 2 on the first side end cover 7, and the second stirring rod 2 on the side of the turntable facing the second side end cover 8 is set with a gap from the first stirring rod 2 on the second side end cover.

[0068] When the reducer 4 starts to work, the second stirring rods 6 on both sides of the turntable 5 cooperate with the first stirring rods 2 on the two end covers to stir the materials, which can increase the stirring rate.

[0069] For example, to prevent the rotation shaft 5 from shifting, in some embodiments of the present invention, a positioning shaft 13 is provided on the second side end cap 8, and a positioning shaft sleeve 15 is provided on the turntable 5. The end of the positioning shaft 13 is inserted into the positioning sleeve 14 and can rotate relative to the positioning sleeve 14. This structure can fix the position structure between the second side end cap 8 and the turntable 5 without affecting the rotation of the rotation shaft 3.

[0070] The second embodiment of the present invention further provides a feeder, comprising the stirring device described above.

[0071] The feeder includes a hopper and a spiral stirring mechanism. The stirring device is part of the feeder, and its inlet 10 is connected to the feeder hopper 12. A feeder equipped with a stirring device can further improve the mixing of the output materials. It should be noted that the stirring device, as the front-end mechanism of the feeder, performs preliminary stirring and mixing on the materials added to the hopper. The materials output through the discharge port 11 are transported through a pipe 14 to the spiral stirring mechanism.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
