[0024] The embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary only, and are merely intended to explain the present application, and cannot be understood as limiting the present application.

[0025] The core of the present application is to provide a tooth cutter and a stirring device, which can improve the shearing speed and rotational speed and realize good stirring and dispersion functions.

[0026] In order to enable those skilled in the art to better understand the technical solutions provided by the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0027] Specifically, referring to Figure 1 The tooth cutter provided by the present application comprises a base 400, a transmission shaft, and a plurality of blades 200.

[0028] The base 400 is used to be installed on the inner cavity side wall of the stirring device, the transmission shaft is rotatably arranged on the base 400, the plurality of blades 200 are arranged on the transmission shaft in the axial direction, and the blade 200 is provided with a cutting edge on one side in the rotating direction. The tooth cutter is arranged close to the side wall, and the material distributed on the side wall of the stirring device can be fully sheared.

[0029] The tooth cutter provided by the present application is installed on the inner cavity side wall of the stirring device, a plurality of blades 200 are arranged on the transmission shaft, and a cutting edge is arranged on one side in the rotating direction of the blade 200, so that the plurality of blades 200 can be rotated at high speed under the driving of the rotating transmission shaft and continuously cut the material, and the good stirring and dispersion functions of the material in the stirring device are realized. In addition, since the material moves up and down in the stirring device under the driving of the paddle, the flow resistance of the material generated by the blade 200 is reduced due to the arrangement of the tooth cutter on the side wall of the stirring device, the shearing effect is enhanced, and the shearing speed and rotational speed of the blade 200 can be further improved.

[0030] In specific embodiments, the end of the transmission shaft away from the base 400 is a conical tip 110, and the conical design can reduce the rotational resistance when the transmission shaft rotates and also reduce the resistance when the material flows.

[0031] As Figure 1As shown, the plurality of blades 200 are arranged at intervals on the transmission shaft, and adjacent two blades 200 in the axial direction of the transmission shaft are staggered in the projection direction, and in particular, the staggered arrangement can be arranged vertically in the projection direction. The blade 200 is a strip-shaped structure, and a mounting hole for inserting the transmission shaft is formed at the center of the strip-shaped structure, and each blade 200 forms two symmetrical cantilever blades on both sides of the transmission shaft, which can realize effective cutting of the peripheral gear cutter.

[0032] In a specific embodiment, the transmission shaft includes a main shaft 300 and a shaft end 100, one end of the main shaft 300 is rotatably connected with the base 400, and the other end is provided with a plurality of blades 200, and the shaft end 100 is arranged at the other end of the main shaft 300; wherein the main shaft 300 and the blade 200 are an integral structure, or the main shaft 300 and the blade 200 are detachably connected. A plurality of blades 200 are arranged at intervals along the edge of the main shaft 300. In one form, the main shaft 300 and the blade 200 are an integral structure, which can be welded to the main shaft 300 or integrally cast, and finally welded to the other end face of the main shaft 300 through the shaft end 100. Of course, in another form, a plurality of clamping grooves can be provided on the main shaft 300, and the blade 200 can be detachably connected to the main shaft 300 by clamping or pinning, and the shaft end 100 can be arranged at the other end of the main shaft 300 by threaded connection.

[0033] The main shaft 300 penetrates the base 400 and is connected with the external driving mechanism to realize rotation. The base 400 can be fixed on the inner cavity side wall of the stirring device by bolts.

[0034] In order to prevent damage to the inner cavity of the stirring device caused by the blade 200 falling off the main shaft 300, the shaft end 100 is provided with a blocking column 120. The blocking column 120 can be welded or detachably connected to the side surface of the shaft end 100.

[0035] In a specific embodiment, the effective cutting length of each blade 200 is less than or equal to twice the diameter of the transmission shaft, and a compact gear cutter structure is adopted, so that the blade 200 can rotate at a high speed, and the material falling into the center of the stirring device is subjected to high-speed shearing, realizing the dispersion function of the material in the stirring device, meeting the needs of different material stirring and dispersion, and improving the compatibility.

[0036] The prior art has a large tool diameter, high motor capacity requirement, and a low shearing speed, which cannot achieve further material refinement, the tool is vertically arranged, only the tool tip can contact the material close to the side wall, resulting in large useless work and low work efficiency. The application of the gear cutter breaks the limitation of the shape of the traditional mixer tool, increases the number of cutting edges, and realizes high linear speed shearing. With the same energy consumption, the material is more accurately mixed, the gear cutter has a small size, further reduces the equipment floor space, and reduces the production cost.

[0037] In addition, the utility model provides a kind of stirring equipment, it is characterized by, including stirring container, driving mechanism and as above specific embodiment gear cutter, gear cutter is arranged in the side wall of stirring container, driving mechanism is used to drive the rotation of transmission shaft of gear cutter.

[0038] Obviously, the stirring equipment comprising the above gear cutter has the same beneficial effects, which will not be repeated here.

[0039] The present application also includes a paddle, which is rotatably arranged at the bottom of the stirring container. The paddle device is one, and the gear cutter device can be multiple arranged circumferentially along the side wall of the stirring container.

[0040] As shown in Figure 1 The gear cutter is small and multi-blade, arranged on the side wall of the stirring equipment in the horizontal direction. The number of blades 200 can be 12 blades 200 (each cantilever blade is regarded as a blade 200), the tail of the blade 200 is connected with the transmission shaft, the transmission shaft drives the blade 200 to rotate at high speed, and the rotating speed of the transmission shaft can reach 70 m / s. At the same time, the paddle arranged at the bottom of the inner cavity of the stirring container rotates at low speed, which can ensure that the material moves in a vortex centrifugal motion in the interior of the stirring container, so that the material rises along the side wall of the stirring container under the action of centrifugal force, and then falls in the central position of the stirring container under the action of gravity, forming the rolling of the material, which further ensures that the material can pass through the gear cutter area. The material is subjected to high-speed shearing by the gear cutter during the rolling process, realizing sufficient stirring and dispersion of the material.

[0041] In order to reasonably utilize the space and maximize the shearing efficiency, the length of the paddle is greater than the length of the gear cutter, and in particular, the length of the paddle is slightly smaller than the diameter of the bottom of the stirring container, so that the material can not sink to the bottom and always circulate and float up and down. At the same time, the gear cutter is designed to be small, the volume of the gear cutter is small, the requirement for the motor and the equipment volume is low, and the increase of production cost is avoided. In addition, the rotating axis of the paddle coincides with the center line of the stirring container, and the rotating axis of the paddle is vertically arranged with the transmission shaft, i.e. the blade 200 is vertically arranged, and the blade 200 will not generate flow resistance to the material during rotation.

[0042] The main process steps of the stirring device in specific use are as follows:

[0043] 1. The material enters the inner cavity of the stirring container from the feeding port of the stirring container;

[0044] 2. The driving mechanism corresponding to the paddle and the cutter is started, the paddle starts to rotate at high speed, the material in the stirring container generates centrifugal force, and the material continuously circulates and sinks in the cavity;

[0045] 3. The cutter rotates at high speed and continuously cuts the material;

[0046] 4. After the material is fully mixed under the action of the cutter and the paddle, the driving mechanism corresponding to the paddle and the cutter is turned off;

[0047] 5. The material flows out of the discharge port of the stirring container.
