By the structure, the chocolate refiner provided by the utility model can stir chocolate raw materials more efficiently, and has higher working efficiency.

However, the prior art represented by the above patent still has the following problems that the stirring blade is driven to rotate only by the rotating shaft to stir the raw materials, so that the raw materials move with a certain rule, and the raw materials are unevenly mixed.

In order to solve the above technical problems, the present embodiment provides a chocolate mixer. The chocolate mixer comprises a shell 1, a driving member 2, a rotating sleeve 3, a transmission member 4 and a stirring paddle 5 as shown in fig. 1 and 5. The housing 1 has a feed inlet 101 and a discharge outlet 102 communicating with the interior of the housing 1 as shown in fig. 1.

In order to prevent foreign matters from entering the shell 1 from the inlet 101 and thus to affect the quality of chocolate, a rotating plate 12 is rotatably installed on the edge of the inlet 101 as shown in fig. 6. The rotating plate 12 moves in the W1 direction toward the feed port 101 to close the feed port 101 as shown in fig. 6. The flap 12 moves away from the inlet 101 in the W2 direction to open the inlet 101 as shown in fig. 6.

And more preferably to prevent the operator from falling into the housing 1 when throwing material into the feed opening 101. As shown in fig. 2, a protective net 11 is arranged on the upper cover of the feed inlet 101.

As shown in fig. 4, the driving member 2 is installed in the housing 1, and the driving member 2 has a first tooth groove on the circumferential side. The rotating sleeve 3 is rotatably arranged in the shell 1 and sleeved outside the driving piece 2. The middle part of the moving part is rotatably arranged on the rotating sleeve 3, and one end of the transmission part 4 is positioned in the rotating sleeve 3 and is provided with a second tooth slot meshed with the first tooth slot. The stirring paddle 5 is arranged on the other end of the transmission piece 4 outside the rotating sleeve 3.

Through the structure, the chocolate mixing machine provided by the embodiment can enable the stirring paddle 5 to revolve around the axis of the rotating sleeve 3 and simultaneously rotate around the axis of the stirring paddle 5, so that raw materials are mixed more uniformly. Specifically, the rotating sleeve 3 rotates relative to the housing 1 to drive the transmission member 4 to revolve around the axis of the rotating sleeve 3, and further drive the stirring paddle 5 to revolve around the axis of the rotating sleeve 3. Simultaneously, the rotating sleeve 3 drives the second tooth groove on the transmission piece 4 to move relative to the first tooth groove, so that the second tooth groove rotates around the axis of the transmission piece 4. So as to drive the transmission member 4 to rotate around the axis of the transmission member 4, thereby causing the stirring paddle 5 to rotate around the axis of the transmission member 4. When the stirring paddle 5 revolves around the axis of the rotating sleeve 3, the stirring paddle can rotate around the axis of the transmission piece 4, so that the raw materials move more randomly, and the raw materials are mixed more uniformly.

In order to prevent the material from solidifying due to an excessively low temperature in the housing 1 during the stirring, the mixing was not uniform. A heating chamber 104 is provided in the side wall of the housing 1 as shown in fig. 3. As shown in fig. 3, the shell 1 is also provided with a water heater 13, and the water heater 13 is communicated with the heating cavity 104 through a water pipe. The above-mentioned water heater 13 is an electric water heater 13 produced by Shanghai's industrial production, and is not described in detail here. The water heater 13 is used to supply hot water into the heating chamber 104. Specifically, the water heater 13 supplies hot water into the heating chamber 104 to raise the temperature of the water in the heating chamber 104, so that the heating chamber 104 supplies heat into the housing 1 to prevent the temperature in the housing 1 from being excessively low.

Based on the above-described basis. As shown in fig. 7, both ends of the connecting rod 21 are respectively mounted on the housing 1. The first bevel gear 22 is sleeved outside the connecting rod 21 and evenly distributed along the axis of the connecting rod 21, and the first tooth grooves are formed in the first bevel gear 22.

Based on the above-described basis. The transmission 4 includes a rotation shaft 41 and a second bevel gear 42 as shown in fig. 8. The middle part of the rotating shaft 41 is rotatably arranged on the side wall of the rotating sleeve 3, one end of the rotating shaft 41 is positioned in the rotating sleeve 3, and the stirring paddle 5 is arranged on the other end of the rotating shaft 41 positioned outside the rotating sleeve 3. A second bevel gear 42 is mounted on one end of the rotating shaft 41 within the rotating sleeve 3 and has a second tooth slot, the second bevel gear 42 being meshed with the first bevel gear 22. Specifically, as shown in fig. 12, the rotating sleeve 3 drives the rotating shaft 41 to rotate around the axis of the rotating sleeve 3 in the W3 direction, so that the second bevel gear 42 rotates around the axis of the first bevel gear 22 in the W3 direction and meshes with the first bevel gear 22, and since the first bevel gear 22 is fixed relative to the connecting rod 21, so that the second bevel gear 42 rotates around the axis of the rotating shaft 41 in the W4 direction, the meshing transmission between the second bevel gear 42 and the first bevel gear 22 is realized. And thus the rotation shaft 41 rotates in the W4 direction about its own axis. So as to drive the stirring paddle 5 to rotate in the direction W4 around the axis of the rotating shaft 41 while rotating in the direction W3 around the axis of the rotating sleeve 3.

Based on the above, in order to make the material mixing more uniform. The stirring paddle 5 includes a paddle handle 51, a first paddle 52, and a second paddle 53 as shown in fig. 9. One end of the paddle handle 51 is coaxially mounted on the other end of the rotating shaft 41 outside the rotating sleeve 3. The first blade 52 and the second blade 53 are L-shaped, and the first blade 52 and the second blade 53 are located on opposite sides of the axis of the paddle handle 51, respectively. One end of the first paddle 52 is mounted on the other end of the paddle handle 51 remote from the rotational shaft 41. One end of the second paddle 53 is mounted on the other end of the paddle handle 51 remote from the rotational shaft 41 and is located on one side of the first paddle 52. The other end of the first paddle 52 and the other end of the second paddle 53 are located on opposite sides of the paddle handle 51, respectively.

Thus, when the paddle handle 51, the first paddle 52 and the second paddle 53 are rotated about the axis of the rotating sleeve 3 in the W3 direction, the paddle handle 51, the first paddle 52 and the second paddle 53 can each agitate the material. When the first and second paddles 52, 53 rotate in the W4 direction about the axis of the rotation shaft 41, the first and second paddles 52, 53 agitate the material. Meanwhile, when the first paddle 52 and the second paddle 53 rotate around the axis of the rotating shaft 41, the other end of the first paddle 52 and the other end of the second paddle 53 away from the paddle handle 51 can both drive the material to move towards the direction close to the paddle handle 51, so that the material is further disturbed, and the material is mixed more uniformly.

Based on the above, in order to prevent the material from adhering to both sides perpendicular to the rotating sleeve 3 in the housing 1. The rotating sleeve 3 includes a sleeve 31, a mounting sleeve 32 and a scraper 33 as shown in fig. 10. One end of the sleeve 31 is rotatably mounted in the housing 1, and the other end passes through the housing 1 and is located outside the housing 1. The sleeve 31 is sleeved outside the connecting rod 21 and the first bevel gear 22 as shown in fig. 13. As shown in fig. 11, through holes 311 are formed in the sleeve 31, and the through holes 311 are in one-to-one correspondence with the first bevel gears 22. In order to prevent adjacent paddles 5 from interfering with each other when rotating about the axis of rotation shaft 41. The through holes 311 are in two rows, the through holes 311 in two rows are alternately and uniformly distributed along the axis of the sleeve 31, and the through holes 311 in adjacent rows are alternately distributed on the sleeve 31. The mounting sleeves 32 are mounted on the outer peripheral side of the sleeve 31 in one-to-one correspondence with the through holes 311 as shown in fig. 10. As shown in fig. 14, the middle part of the rotating shaft 41 is rotatably mounted inside the mounting sleeve 32, one end of the rotating shaft 41 sequentially passes through the mounting sleeve 32 and the through hole 311 and is positioned inside the sleeve 31, and the other end of the rotating shaft 41 passes through the mounting sleeve 32 and is positioned outside the mounting sleeve 32. As shown in fig. 10, one ends of two scrapers 33 are respectively mounted at both ends of the sleeve 31, and the other ends of the two scrapers 33 each extend in a direction away from the sleeve 31 in a radial direction of the sleeve 31. The side surfaces of the two scrapers 33 facing the housing 1 are respectively abutted against two opposite inner walls of the housing 1. In this way, when the sleeve 31 rotates around the axis of the sleeve 31, the scraping plate 33 can be driven to move relative to the two inner walls of the sleeve 32 of the housing 1, so as to scrape off the materials adhered to the inner walls of the housing 1.

Meanwhile, as shown in fig. 12, the rotating sleeve 3 drives the rotating shaft 41 to rotate around the axis of the rotating sleeve 3 along the W3 direction, so that the second bevel gear 42 rotates around the axis of the first bevel gear 22 along the W3 direction and is meshed with the first bevel gear 22, and as the first bevel gear 22 is fixed relative to the connecting rod 21, the second bevel gear 42 rotates around the axis of the rotating shaft 41 along the W4 direction, so that meshing transmission between the second bevel gear 42 and the first bevel gear 22 is realized. And thus the rotation shaft 41 rotates in the W4 direction about its own axis. To rotate the handle, the first paddle 52 and the second paddle 53 in the W4 direction about the axis of the rotation shaft 41. And causes agitation of the material by the first blade 52 and the second blade 53. Simultaneously, the other end of the first paddle 52 and the other end of the second paddle 53 far away from the paddle handle 51 can drive the material to move towards the direction close to the paddle handle 51, so that the material is further disturbed, and the material is mixed more uniformly.
