[0041] The utility model proposes a double-axis counter-rotating synchronous drive mixer, comprising a drive assembly 90, a first transmission shaft 10, a second transmission shaft 20, a synchronization assembly 60 and a first fastener 40, wherein one end of the first transmission shaft is connected to the drive assembly 90, and the first transmission shaft 10 is provided with a first bevel gear 31; the second transmission shaft 20 is arranged opposite to the first transmission shaft 10, and the second transmission shaft 20 is provided with a second bevel gear 32; one end of the synchronization assembly 60 is connected to the first bevel gear 31, and the other end is connected to the second bevel gear 32; the first fastener 40 is provided on the side of the first bevel gear 31 away from the synchronization assembly 60, and the side of the second bevel gear 32 away from the synchronization assembly 60; wherein, when the first transmission shaft 10 rotates, the second transmission shaft 20 is driven to rotate in the opposite direction through the synchronization assembly 60.

[0042] In one embodiment, the first transmission shaft 10 and the second transmission shaft 20 are arranged parallel to each other. When the driving assembly 90 drives the first transmission shaft 10 to rotate, the synchronization assembly 60 is used to realize that the first transmission shaft 10 drives the second transmission shaft 20 to rotate simultaneously.

[0043] The synchronization assembly 60 is arranged vertically relative to the first transmission shaft 10 and the second transmission shaft 20 , and the first bevel gear 31 and the second bevel gear 32 are respectively arranged on the first transmission shaft 10 and the second transmission shaft 20 , so as to realize axial vertical transmission.

[0044] Specifically, the synchronization assembly 60 includes a synchronization shaft 61 and a third bevel gear 62, and the synchronization shaft 61 is arranged between the first transmission shaft 10 and the second transmission shaft 20; a third bevel gear 62 is respectively provided at both ends of the synchronization shaft 61, one of the third bevel gears 62 is meshed with the first bevel gear 31, and the other third bevel gear 62 is meshed with the second bevel gear 32.

[0045] The two third bevel gears 62 are respectively arranged on the left and right sides of the synchronization shaft 61, the first bevel gear 31 is arranged at the middle position of the first transmission shaft 10, and the second bevel gear 32 is also arranged at the middle position of the second transmission shaft 20. The two third bevel gears 62 are respectively meshed with the first bevel gear 31 and the second bevel gear 32. Therefore, when the driving assembly 90 drives the first transmission shaft 10 to rotate, the first transmission shaft 10 drives the first bevel gear 31 to rotate; the first bevel gear 31 drives the third bevel gear 62 meshed with it to rotate, and then drives the synchronization shaft 61 and the third bevel gear 62 on the other side to rotate; and then drives the second bevel gear 32 meshed with it and the second transmission shaft 20 to rotate.

[0046] Understandable, please refer to Figure 1 , the synchronization assembly 60 is located between the first transmission shaft 10 and the second transmission shaft 20, wherein the first bevel gear 31 is located on the right side of the third bevel gear 62 meshing therewith, and the second bevel gear 32 is located on the left side of the third bevel gear 62 meshing therewith. Therefore, when the first transmission shaft 10 rotates clockwise, the corresponding second transmission shaft 20 rotates counterclockwise. When the first transmission shaft 10 rotates counterclockwise, the second transmission shaft 20 rotates clockwise. Thus, the first transmission shaft 10 and the second transmission shaft 20 are synchronously rotated in opposite directions. When applied to a mixer, the mixing and stirring effect can be improved.

[0047] During the above operation, a ring-shaped or semi-ring-shaped groove 70 is formed on the side wall of the first transmission shaft 10 along the circumferential direction, and the first fastener 40 is arranged in the groove 70 .

[0048] The slot 70 has a certain depth, so the lower half of the first fastener 40 is engaged in the slot 70, and the upper half is exposed outside the slot 70. And the portion of the first fastener 40 exposed outside the slot 70 abuts against the first bevel gear 31. Figure 2 and Figure 3 The third bevel gear 62 abuts against the left side of the first bevel gear 31 , and the first fastener 40 abuts against the right side of the first bevel gear 31 , thereby limiting the first bevel gear 31 and further limiting the first transmission shaft 10 .

[0049] In addition, the second transmission shaft 20 is also provided with the same structures as the slot 70, the first and the fixing, so as to limit the second transmission shaft 20. Therefore, the first transmission shaft 10 and the second transmission shaft 20 are fixed by the first fastener 40 to ensure the stability of the rotation of the first transmission shaft 10 and the second transmission shaft 20 during the above operation to prevent shaking.

[0050] The technical solution of the utility model realizes the synchronous rotation of the first transmission shaft 10 and the second transmission shaft 20 through the synchronization component 60. In addition, the first fastener 40 is used to cooperate with the transmission component to position the first transmission shaft 10 and the second transmission shaft 20, thereby improving the stability of the first transmission shaft 10 and the second transmission shaft 20 during the rotation process, preventing the first transmission shaft 10 and the second transmission shaft 20 from being unable to rotate at the same frequency due to interference from external factors such as vibration during the operation of the equipment, thereby ensuring the stability of the equipment during operation and improving the transmission efficiency.

[0051] In one embodiment, please refer to Figure 4 The first fastener 40 is a gear ring. A ring-shaped groove 70 extending circumferentially is provided on the side wall of the first transmission shaft 10 . The gear ring is disposed in the groove 70 , and a portion of the gear ring protrudes from the groove 70 .

[0052] The portion of the gear ring protruding from the slot 70 abuts against the end of the first bevel gear 31 away from the synchronization assembly 60 ; or the portion of the gear ring protruding from the slot 70 abuts against the end of the second bevel gear 32 away from the synchronization assembly 60 .

[0053] In this embodiment, the gear ring can be in a semicircular ring shape, and the corresponding slot 70 is in a semicircular ring shape, and the shape is adapted to the gear ring to ensure that when the gear ring is engaged in the slot 70, the gear ring can be stably engaged in the slot 70.

[0054] In addition, two semicircular rings can be spliced ​​to form a circular ring structure. The slot 70 is circular, and its shape is adapted to the circular ring structure after the two semicircular rings are spliced, so as to ensure that when the gear ring is clamped in the slot 70, the gear ring can be stably clamped in the slot 70. Among them, the two semicircular ring sleeves are respectively sleeved on both sides of the first transmission shaft 10, and the inner diameter of the circular ring structure formed is adapted to the diameter of the first transmission shaft 10, so as to ensure that the formed circular ring structure can be stably clamped on the first transmission shaft 10. In addition, the method of splicing two semicircular rings can make it easier for operators to install.

[0055] In one embodiment, the dual-axis counter-rotating synchronous drive mixer also includes a flat key 50, a first avoidance groove is provided on the first bevel gear 31, and a second avoidance groove is provided on the first transmission shaft 10 at the position of the first avoidance groove, the first avoidance groove is connected to the second avoidance groove to form an installation gap 80, and the flat key 50 is arranged in the installation gap 80.

The end of the first bevel gear 31 is recessed inward to form a first avoidance groove, and at a position corresponding to the first avoidance groove, the side wall of the first transmission shaft 10 is also recessed inward to form a second avoidance groove.

[0057] The first avoidance groove and the second avoidance groove are spliced ​​to form an installation gap 80 for accommodating the flat key 50. The flat key 50 is used to connect, thereby improving the limiting effect on the first bevel gear 31 and preventing the first bevel gear 31 from sliding on the first transmission shaft 10.

Both the first mounting hole and the second mounting hole can be threaded holes. The first mounting hole and the second mounting hole are located in corresponding positions.

[0059] In addition, the same structures such as the first avoidance groove, the second avoidance groove, the flat key 50 , the first mounting hole and the second mounting hole may be provided on the second transmission shaft 20 , so as to further improve the stability of the second transmission shaft 20 and the second bevel gear 32 .

[0064] In this embodiment, the mounting portion 612 and the connecting portion 611 are integrally formed. The diameter of the mounting portion 612 is set to be slightly smaller than that of the connecting portion 611, thereby forming a stepped structure with a height difference.

[0065] The side of the second fastener 63 facing away from the third bevel gear 62 is abutted against the side wall of the connecting portion 611 protruding from the mounting portion 612, thereby limiting the second fastener 63, further improving the limiting effect of the second fastener 63, and improving the stability of the synchronization assembly 60 during operation.

[0066] Similarly, the second fastener 63 is disposed on one side of another third bevel gear 62 to also improve its stability during operation.
