Figure 3 It is a schematic structural diagram of the corrugated sleeve 107 and the contact wheel 108 of the first embodiment of the utility model.

[0021] The fiber stirring device of the utility model includes a stirring tank 101, a main shaft 102, a sleeve 103, a stirring rod 104, a stopper 105, a spring 106, a corrugated sleeve 107, a contact wheel 108, a stopper groove 109, a protrusion 110, a cross arm 111, an inclined rod 112, a driven wheel 113, a driving motor 114, a driving wheel 115, and a belt 116, which solves the problem that the existing technology uses the rotation of the stirring shaft to drive the blades for stirring, and the simple circumferential rotation cannot generate enough turbulence, making it difficult to mix the materials evenly. It can be understood that the above scheme can also be used to improve product quality.

[0022] In this embodiment, the stirring tank 101 is a cylindrical tank body with a feed hopper on the top and a discharge port on the bottom. The stirring assembly is installed on the stirring tank 101, thereby solving the problem in the prior art that the simple circumferential rotation cannot generate sufficient turbulence, making it difficult to mix the materials evenly because the rotation of the stirring shaft is used to drive the blades for stirring.

[0023] The main shaft 102 extends into the mixing tank 101 and is rotatably connected to the mixing tank 101. The sleeve 103 is sleeved on the outside of the main shaft 102 and is slidably connected to the main shaft 102 and is located in the mixing tank 101. The stirring rod 104 is fixedly installed on the sleeve 103. The limit block 105 is fixedly connected to the main shaft 102 and is located at the bottom end of the main shaft 102. The spring 106 is sleeved on the outside of the main shaft 102 and is located between the limit block 105 and the sleeve 103. The corrugated sleeve 107 is sleeved on the outside of the sleeve 103 and is slidably connected to the main shaft 102. The sleeve 103 is fixedly connected, the contact wheel 108 is connected to the stirring tank 101 through the support, the support is installed in the stirring tank 101 and supports the contact wheel 108, the contact wheel 108 is in contact with the corrugated sleeve 107, the driving member drives the main shaft 102 to rotate, the top of the stirring tank 101 is provided with a mounting hole, the main shaft 102 passes through the mounting hole and is connected to the stirring tank 101 through a bearing, the driving member is used to drive the main shaft 102 to rotate, the sleeve 103 is a cylinder with an internal cavity, sleeved on the outside of the main shaft 102, the sleeve 1 03 can rotate with the main shaft 102 and can also move vertically along the main shaft 102. The number of the stirring rods 104 is multiple, and they are arranged in an annular shape on the outside of the sleeve 103. The stirring rods 104 are provided with stirring blades to improve the stirring effect. The limit block 105 is disc-shaped and is used to support and limit the spring 106. The spring 106 is arranged between the limit block 105 and the sleeve 103, and can provide elastic support for the sleeve 103. The corrugated sleeve 107 is annular and is located at the top of the sleeve 103. The top of the corrugated sleeve 107 is wavy. The contact wheel 108 is installed above the corrugated sleeve 107 through the support. When the sleeve 103 rotates with the main shaft 102, the contact wheel 108 presses on the corrugated sleeve 107, and cooperates with the elastic force of the spring 106 to make the sleeve 103 reciprocate vertically, so that the stirring rod 104 will continuously rise and fall while rotating circumferentially, thereby generating sufficient turbulence and improving the uniformity of stirring. This solves the problem that the existing technology uses the rotation of the stirring shaft to drive the blades for stirring, and the simple circumferential rotation cannot generate sufficient turbulence, making it difficult to mix the materials evenly.

[0024] Secondly, the limiting groove 109 is located on the side of the main shaft 102 close to the sleeve 103; the protrusion 110 cooperates with the limiting groove 109, the limiting groove 109 is located on the outer surface of the main shaft 102, and the protrusion 110 is located on the inner wall of the sleeve 103, and the limiting of the sleeve 103 is achieved through the cooperation between the limiting groove 109 and the protrusion 110.

[0025] At the same time, the driven wheel 113 is sleeved on the outside of the main shaft 102 and fixedly connected to the main shaft 102; the driving motor 114 is installed on the stirring tank 101 and is located on the side of the stirring tank 101 close to the driven wheel 113; the driving wheel 115 is fixedly connected to the output shaft of the driving motor 114; the belt 116 connects the driving wheel 115 and the driven wheel 113, and the driving motor 114 is provided with a matching controller. Through the controller, the driving motor 114 can be operated according to the set direction, speed and time. The controller can be set to meet different stirring requirements. The driving motor 114 drives the driving wheel 115 to rotate, and under the transmission action of the belt 116 and the driven wheel 113, the main shaft 102 is driven to rotate.

[0026] In addition, the cross arm 111 is fixedly connected to the inner wall of the stirring tank 101, and the contact wheel 108 is installed on the cross arm 111; the two ends of the inclined rod 112 are respectively connected to the inner wall of the stirring tank 101 and the cross arm 111, and the cross arm 111 is horizontally installed on the inner wall of the stirring tank 101.

The two ends of the inclined rod 112 are respectively connected to the cross arm 111 and the inner wall of the stirring tank 101 to form a triangular stable structure to improve the stability of the support. The contact wheel 108 is stably supported through the cross arm 111 and the inclined rod 112.

[0027] In this embodiment, during stirring, the drive motor 114 is started, and the drive motor 114 drives the main shaft 102 to rotate, so that the sleeve 103 drives the stirring rod 104 to rotate circumferentially. While the sleeve 103 rotates, the corrugated sleeve 107, the contact wheel 108 and the spring 106 cooperate with each other, so that the sleeve 103 drives the stirring rod 104 to rise and fall, thereby generating sufficient turbulence and improving the uniformity of stirring. This solves the problem that the existing technology uses the rotation of the stirring shaft to drive the blades for stirring, and the simple circumferential rotation cannot generate sufficient turbulence, making it difficult to mix the materials evenly.
