[0018] Implementing the present utility model has the following beneficial effects:

[0019] An embodiment of the utility model discloses a driving device for a cold drink machine. The cold drink machine includes a main body, an evaporator for refrigeration, and a rotary scraper for scraping the surface of the evaporator. The driving device is characterized in that it includes an output shaft for driving the rotary scraper to rotate, a driving motor, and a speed-changing gearbox. The driving motor drives the output shaft to rotate through the speed-changing gearbox;

[0020] Among them, the driving motor includes an input shaft and a motor main body for driving the input shaft to rotate. The speed-changing gearbox is provided with an input end for the input shaft to access and an output end for the output shaft to access. One end of the input shaft is inserted into the input end, and the other end is provided with a cooling fan;

[0021] One end of the output shaft is inserted into the output end, and the other end passes through the inside of the evaporator and is connected to the rotary scraper. Thus, only a single motor driving source is required to complete the driving of the rotary scraper and the driving of the cooling fan. At the same time, under the deceleration of the speed-changing gearbox, the rotary scraper can be at a normal operating speed.

[0022] Moreover, the input end and the output end are respectively arranged on both side end faces of the speed-changing gearbox, so as to form a relatively cold space adjacent to the evaporator and a heat dissipation space for installing control components in the main body of the machine through the speed-changing gearbox. The cooling fan is located in the heat dissipation space to dissipate heat from the heat dissipation space. At the same time, the partition setting of the speed-changing gearbox can greatly weaken the heat conduction of the driving motor to the evaporator. Description of the Drawings

[0025] Figure 3 is an exploded structural diagram of the driving device of the utility model Detailed Embodiment

[0026] To make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] See Figure 1 、 23, embodiments of the present utility model provide a driving device for a cold drink machine. The cold drink machine includes a main body 1, an evaporator 2 for refrigeration, and a rotary scraper 3 for scraping the surface substances of the evaporator 2. The driving device includes an output shaft 4 for driving the rotary scraper 3 to rotate, a driving motor 5, and a speed change gearbox. The driving motor 5 drives the output shaft 4 to rotate through the speed change gearbox;

[0028] Among them, the driving motor 5 includes an input shaft 51 and a motor main body 52 for driving the input shaft 51 to rotate. The speed change gearbox is provided with an input end for the input shaft 51 to access and an output end for the output shaft 4 to access. One end of the input shaft 51 is inserted into the input end, and the other end is provided with a cooling fan 511;

[0029] One end of the output shaft 4 is inserted into the output end, and the other end passes through the inside of the evaporator 2 and is connected to the rotary scraper 3;

[0030] The input end and the output end are respectively arranged on the two side end faces of the speed change gearbox, so as to form a cold-biased space a adjacent to the evaporator 2 and a heat dissipation space b for installing control components in the main body 1 through the speed change gearbox. The cooling fan 511 is located in the heat dissipation space b.

[0031] Specifically, the speed change gearbox includes a partition box body 6 and a speed change gear set installed in the partition box body 6. The speed change gear set includes at least two speed change gears 61 to realize the decelerated output of the driving motor 5 to the output shaft 4.

[0032] Correspondingly, since the volume of the partition box body 6 needs to be adapted according to the actual space size in the main body 1, when the distance between the input end and the output end is too large, it is necessary to add a corresponding number of speed change gears 61 for power transmission to avoid the problem of too large a single speed change gear 61. Preferably, according to the shape and size of the cold-biased space and the heat dissipation space b separated by the speed change gearbox, the number of the speed change gears 61 is increased or decreased

[0033] On the other hand, when there are too many speed change gears 61, in order to facilitate the discrimination and assembly of production workers, the diameters of the speed change gears 61 are different. The partition box body 6 is provided with gear identification grooves 62 corresponding to and adapted to the speed change gears 61 one by one, so as to guide the installation of the speed change gears 61 through the dimensional assembly relationship between the gear identification grooves 62 and the speed change gears 61.

[0034] Since the speed change gearbox is generally large and needs to be installed and fixed within the main body 1, which increases the assembly difficulty, the drive device further includes an auxiliary connecting plate 7. The speed change gearbox is connected to the main body 1 through the auxiliary connecting plate 7. Plug-in slots 71 are provided on both sides of the auxiliary connecting plate 7, and the main body 1 is provided with plug-in posts 11 corresponding to the plug-in slots 71. Therefore, the speed change gearbox can be first connected to the auxiliary connecting plate 7, and then the plug-in posts 11 are inserted into the plug-in slots 71 to quickly complete the preliminary connection between the speed change gearbox and the main body 1.

[0035] Correspondingly, connection ears 63 for connecting to the auxiliary connecting plate 7 are provided on both side walls of the partition box body 6. Ear holding seats 72 for holding the two connection ears 63 are provided on both sides of the auxiliary connecting plate 7. The ear holding seats 72 are provided with ear holding openings 721 adapted to the outer contour of the connection ears 63 for the insertion of the connection ears 63. This facilitates the connection between the partition box body 6 and the auxiliary connecting plate 7.

[0036] Furthermore, on the auxiliary connecting plate 7, ear holding connection posts 722 are provided in the ear holding openings 721, and the connection ears 63 are provided with ear holes 631 adapted to the ear holding connection posts 722 for the insertion of the ear holding connection posts 722. Preferably, the plug-in slots 71 and the plug-in posts 11, the ear holding connection posts 722 and the ear holes 631 can all be connected and fixed by opening screw holes and then using bolts for connection.

[0037] The drive device further includes a silicon steel seat composed of laminated silicon steel sheets (not shown in the figure). The silicon steel seat is provided with a motor mounting hole adapted to the motor main body 52 for the insertion and installation of the motor main body 52. Therefore, the setting of the silicon steel seat can improve the energy efficiency of the drive motor 5 while also being used for the stable installation of the drive motor 5.

[0038] One end face of the partition box body 6 is provided with a motor mounting seat 64 for mounting and connecting the drive motor 5, and the motor mounting seats 64 are provided on both sides of the silicon steel seat;

[0039] The motor mounting seat 64 and the silicon steel seat are respectively provided with corresponding base connection holes and support connection holes. A connecting rod (not shown in the figure) for supporting the silicon steel seat is connected to the base connection hole, and the connecting rod passes through the support connection hole, thereby playing a role in supporting the silicon steel seat.

[0040] The silicon steel seat is also equipped with a pressing connection piece 65. Both ends of the connecting rod are respectively connected to the pressing connection piece 65 and the base connection hole to press and connect the silicon steel seat to the motor mounting seat 64.

[0041] The above are the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
