DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] like Figures 1-2 As shown in an illustrative embodiment of the quick-disassembly and detachable flying knife stirring device of this utility model, the quick-disassembly and detachable flying knife stirring device includes a stirring shaft 1, a flying knife stirring assembly 2, and a fixing assembly 3.

[0033] Multiple flying knife stirring components 2 are sleeved and installed on the stirring shaft 1. Two sets of fixing components 3 are provided, both fixedly installed on the stirring shaft 1. Each flying knife stirring component 2 is located between two fixing components 3, which clamp and fix the multiple flying knife stirring components 2 stacked on top of each other. How the fixing components 3 are fixedly installed or detachably installed on the stirring shaft 1 is prior art and not the point of this application.

[0034] The fly-knife stirring assembly 2 comprises a base mounting seat 21, a quick-release mounting seat 22 and a fly-knife blade 23. The base mounting seat 21 is sleeved on the stirring shaft 1 and is provided with a first mounting groove 24, the outer side of which extends to the outer side wall of the base mounting seat 21, so that the quick-release mounting seat 22 is radially inserted into the first mounting groove 24 and is fixedly connected with the base mounting seat 21 through a fixing bolt 25 perpendicular to the stirring shaft 1. The quick-release mounting seat 22 is provided with a second mounting groove 26, the upper side and the outer side of which extend to the top surface and the outer side wall of the quick-release mounting seat 22 respectively, so that the inner end of the fly-knife blade 23 is axially inserted into the second mounting groove 26 and the remaining part of the fly-knife blade 23 radially extends out of the second mounting groove 26 and extends to the outer side. The inner end of the fly-knife blade 23 is provided with a positioning pin 27. Since the upper side of the first mounting groove 24 extends to the top surface of the base mounting seat 21, the top surface of the quick-release mounting seat 22 faces the bottom surface of the base mounting seat 21 of the adjacent fly-knife stirring assembly 2, the base mounting seat 21 of the adjacent fly-knife stirring assembly 2 presses the inner end of the fly-knife blade 23 and simultaneously presses one end of the positioning pin 27, and the other end of the positioning pin 27 is limitedly fixed in a pin hole 201 provided on the quick-release mounting seat 22, the positioning pin 27 limits the fly-knife blade 23 in the radial direction to avoid the fly-knife blade 23 from being thrown out of the second mounting groove 26 in the rotation process under the action of centrifugal force, thereby maintaining the connection stability.

[0035] The stirring shaft 1 is connected with the output shaft of a speed reducer on the stirring machine and rotates under the driving of the output shaft. The fixed assembly 3 clamps the fly-knife stirring assembly 2 to rotate, so that the fly-knife blades 23 on each fly-knife stirring assembly 2 shear, crush and mix the materials in the stirring barrel.

[0036] When one of the fly-knife blades 23 needs to be replaced, since the fixing bolt 25 is perpendicular to the stirring shaft 1, i.e. the fixing bolt 25 is on a plane perpendicular to the stirring shaft 1, and the head of the fixing bolt 25 is located on the outer side surface of the quick-release mounting seat 22 and is exposed, a tool can directly rotate the fixing bolt 25 to detach the quick-release mounting seat 22 from the base mounting seat 21 and disconnect the quick-release mounting seat 22 from the base mounting seat 21. Further, since the first mounting groove 24 extends to the outer wall of the base mounting seat 21, the quick-release mounting seat 22 is radially pulled out of the first mounting groove 24, the second mounting groove 26 is removed from below the base mounting seat 21 of the adjacent fly-knife stirring assembly 2, and the inner end of the fly-knife blade 23 is exposed. At this time, the fly-knife blade 23 can be axially removed from the second mounting groove 26 to complete the disassembly of the fly-knife blade 23. The reverse operation can be performed to install the fly-knife blade 23. During the disassembly and installation of the fly-knife blade 23, the fixed assemblies 3 at both ends keep clamping each fly-knife stirring assembly 2, and the adjacent fly-knife stirring assembly 2 does not need to be moved or disassembled.

[0037] In addition, the inner end of the second mounting groove 26 extends to the inner side surface of the quick-release mounting seat 22, so that when the flying knife blade 23 is broken, the inner end of the flying knife blade 23 remaining in the second mounting groove 26 can be taken out through the openings on both sides of the second mounting groove 26 after the quick-release mounting seat 22 is removed, without the need for tools and convenient operation.

[0038] In the above exemplary embodiment, the flying knife type stirring device capable of quick disassembly is realized by installing the quick-release mounting seat 22 capable of being radially disassembled on the base mounting seat 21, realizing the limiting installation of the flying knife blade 23, and the stable connection of the flying knife blade 23 can be ensured by fixing the quick-release mounting seat 22 and the base mounting seat 21 through the fixing bolts 25. The disassembly structure is simple, the quick-release mounting seat 22 can be radially extracted by only removing the fixing bolts 25 when the flying knife blade 23 is disassembled, and then the flying knife blade 23 is axially pulled out, without the need for operating the remaining flying knife stirring assembly 2, so that the disassembly operation is simple and convenient. The flying knife blade 23 still remains inserted in the groove structure and is limited by the radial limiting of the positioning pin 27, which is the same as the original structure, so that the flying knife blade 23 does not need to be modified, only the combined structure of the base mounting seat 21 and the quick-release mounting seat 22 needs to be replaced, which is easy to modify and solves the problem of complicated disassembly steps of the flying knife blade 23 of the current flying knife type stirring device.

[0039] In some embodiments, the inner end of the flying knife blade 23 is provided with a limiting block 28 on both sides, and the limiting block 28 is inserted into the radial limiting groove 29 provided on the inner wall of the second mounting groove 26. By inserting and connecting the limiting block 28 and the radial limiting groove 29, the radial limiting of the flying knife blade 23 is further strengthened, the centrifugal force of the flying knife stirring device during rotation is borne by the two limiting blocks 28 and the positioning pin 27, the breakage of the positioning pin 27 caused by excessive centrifugal force is avoided, and the stability of the limiting fixation of the flying knife blade 23 is ensured. In addition, the inner end of the flying knife blade 23 is in a cross-shaped structure due to the limiting blocks 28 on both sides, which improves the structural strength of the inner end of the flying knife blade 23, thereby improving the connection strength between the inner and outer parts of the flying knife blade 23 in the base mounting seat 21, improving the service life of the flying knife blade 23 under high-speed rotation, and reducing the risk of breakage of the flying knife blade 23.

[0040] In some embodiments, two fixing bolts 25 are provided, and the two fixing bolts 25 are respectively arranged through the two limiting blocks 28, so that the fixing bolts 25 limit and fix the limiting blocks 28, and the connection stability of the flying knife blade 23 and the quick-release mounting seat 22 is further improved.

[0041] In some embodiments, the two fixing bolts 25 are radially arranged with an included angle between them, that is, the spacing between the two fixing bolts 25 gradually decreases from outside to inside, which forms a clamping effect on the fixing of the flying knife blade 23, thereby further improving the connection stability of the flying knife blade 23. In addition, the fixing bolt 25 is kept in the radial direction, and more withstands the centrifugal force, so that the threads of the outer wall of the fixing bolt 25 are in closer contact with the threads of the inner wall of the threaded hole, improving the self-locking effect of the threaded connection of the fixing bolt 25.

[0042] In some embodiments, one end of the positioning pin 27 passes through the pin hole 201 and presses on the inner surface of the first mounting groove 24, so that after the quick release mounting seat 22 is radially pulled out of the first mounting groove 24, the positioning pin 27 can extend downward by its own gravity out of the quick release mounting seat 22 and out of the pin hole 201, eliminating the radial limitation of the positioning pin 27 on the flying knife blade 23, so that the flying knife blade 23 can be directly pulled out radially from the second mounting groove 26, improving the convenience of disassembly. In addition, when limited and installed, the two ends of the positioning pin 27 can receive more direct clamping force, improving its installation stability.

[0043] In some embodiments, the base mounting seat 21 is centrally provided with an assembly hole 202, and the stirring shaft 1 passes through the assembly hole 202. The cross section of the stirring shaft 1 is polygonal, and the assembly hole 202 is matched therewith. The polygonal cross section makes the outer wall of the stirring shaft 1 have multiple planar sections, which can transmit torque through surface contact when matched with the assembly hole 202, achieving limitation and driving of the base mounting seat 21 in the circumferential direction, improving the stability of the flying knife stirring assembly 2 in the circumferential direction after installation, and reducing the pressure of the two-end fixing assembly 3 clamping fixation. In addition, by facing the outer wall of the stirring shaft 1 with different planes of the flying knife blade 23 of the adjacent flying knife blade 23 assembly, the angle position of the flying knife blade 23 of the upper and lower adjacent flying knife stirring assemblies 2 can be staggered, which facilitates the setting of the flying knife stirring assembly 2 in a state with better stirring effect.

[0044] In some embodiments, the end surface of the inner end of the flying knife blade 23 is in surface contact with the surface of the stirring shaft 1, so that the outer wall of the stirring shaft 1 limits and drives the flying knife blade 23 while limiting and driving the base mounting seat 21 in the circumferential direction, improving the stability of the flying knife blade 23 in the circumferential direction, enabling it to cut materials with greater viscosity and strength, and improving the stirring effect.

[0045] In some embodiments, the base seat 21 is in the shape of a round cake, and the outer surface of the quick-release seat 22 matches the outer surface of the base seat 21 to form a circular arc surface, so that the flying knife stirring assembly 2 is smooth in structure outside the flying knife blade 23, and the material flows smoothly on the wall during rotation, avoiding the quick-release seat 22 protruding or being recessed relative to the base seat 21, so that the material is left in the joint of the quick-release seat 22 and the base seat 21 during rotation, ensuring smooth material flow and full mixing.

[0046] It should be noted that: the various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts of each embodiment can be referred to.

[0047] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit it. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the specific embodiments of the present application can be modified or some technical features can be replaced by equivalent ones without departing from the spirit of the present application. They should be covered in the technical solution range of the present application.
