Detailed implementation manners

[0028] In order 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 and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. It should be noted that when an element is referred to as "connected" or "communicated with" another element, it can be directly connected to the other element or connected to the other element through other intermediate elements.

[0029] As Figure 1-6 shown, this embodiment provides a stirring and discharging device, including:

[0030] A mixing pot 41, in which a stirrer 43 is provided. The stirrer 43 passes through the mixing pot 41 and is connected to a stirring motor 44. A plurality of feed pipes 45 are connected to the mixing pot 41, and the lower end of the mixing pot 41 is open.

[0031] A bottom pot frame 42, which is arranged below the mixing pot 41, includes a blanking channel 421, a cover plate 422 arranged in the blanking channel 421, and a cover plate driving mechanism that can drive the cover plate 422 to move to close or open the lower port of the mixing pot 41.

[0032] Compared with the prior art, the stirring and discharging device provided in this embodiment includes two parts: a stirring pot 41 and a bottom frame 42. The stirring pot 41 is used to heat, stir and mix the original popcorn and the flavoring slurry. After the stirring is completed, there is no need to turn it over and pour. Only by turning the cover plate 422 up and down can the bottom of the stirring pot 41 be opened, so as to discharge the stirred popcorn into the cup below. The discharge is cleaner, the structural design is ingenious and compact, occupying less space, and the falling popcorn is guided and limited by the material falling channel 421, so that it is easier to discharge the stirred popcorn into the cup without spilling easily. Moreover, by controlling the moving range of the cover plate 422, the opening size of the stirring pot 41 can be adjusted, so as to facilitate adapting to cups with different diameters.

[0033] As a preferred solution of this embodiment, one side of the cover plate 422 is pivotally connected to the material falling channel 421, and the cover plate driving mechanism can drive the cover plate 422 to perform up and down flipping motion. When the cover plate 422 flips upward, it can closely adhere to and seal the lower port of the stirring pot 41, and when it flips downward, it can open the lower port of the stirring pot 41. Further, preferably, the cover plate driving mechanism includes a cover plate motor 423, a driving gear 424 provided at the output end of the cover plate motor 423, and a sector gear 425 provided on the back surface of the cover plate 422. The driving gear 424 meshes with the sector gear 425. The cover plate motor 423 can drive the cover plate 422 to perform up and down flipping motion through the transmission of the driving gear 424 and the sector gear 425. A sealing ring 411 is provided at the lower port of the stirring pot 41, and can achieve sealing when the cover plate 422 flips upward to press against the lower port of the stirring pot 41. In this solution, by setting the sector gear 425, the rotational torque transmitted from the cover plate motor 423 to the cover plate 422 can be amplified, and the pressure of the cover plate 422 pressing against the lower port of the stirring pot 41 can be increased, thereby increasing the sealing effect, and the structure is simple and the work is stable.

[0034] As a preferred solution of this embodiment, the cover plate driving mechanism further includes a second travel switch 426 for detecting the flipping angle of the cover plate 422, which can control the cover plate 422 to be in an inclined state obliquely downward in the cleaning state, and preferably the downward inclination angle range is 30°-60°. Since the upper surface of the cover plate 422 is located at the bottom of the pot when the stirring pot 41 is stirring, it is easier to accumulate some viscous slurries such as syrup and oil. By setting the cover plate 422 in an inclined state obliquely downward in the cleaning state, it is easier to clean the upper surface of the cover plate 422.

[0035] As a preferred solution of this embodiment, it further includes a cleaning mechanism 9. The cleaning mechanism 9 includes a nozzle 91, a water receiving funnel 92, a lifting mechanism 93 and a waste water tank 94. The nozzle 91 is arranged on the mixing pot 41 and can spray cleaning water into it. The water receiving funnel 92 is located below the blanking channel 421 and can be driven by the lifting mechanism 93 to move up and down. When the water receiving funnel 92 moves to the lower dead point, a clearance space for the cup to pass through can be formed between the water receiving funnel 92 and the blanking channel 421. When the water receiving funnel 92 moves to the upper dead point, the water receiving funnel 92 can receive the cleaning waste water falling from the blanking channel 421 and introduce the cleaning waste water into the waste water tank 94. In this solution, by setting the cleaning mechanism 9, and the cleaning mechanism 9 includes a water receiving funnel 92 that can move up and down, the water receiving funnel 92 can be lowered to form a clearance space when the cup transporting mechanism transports the cup to the lower part of the blanking channel 421 to receive the material, and the water receiving funnel 92 can be raised to receive the cleaning waste water falling from the blanking channel 421 and introduce the cleaning waste water into the waste water tank 94 when cleaning is required.

[0036] As a preferred solution of this embodiment, the lifting mechanism 93 includes a mounting frame 931, a vertical track 932 provided on the mounting frame 931, a slider 933 cooperating with the track, a connecting frame 934 connecting the slider 933, a lifting motor 935 for driving the slider 933 to move up and down along the track, a transmission belt group 936, and a first travel switch 937 for controlling the stroke range of the water receiving funnel 92. The water receiving funnel 92 is mounted on the connecting frame 934.

[0037] As a preferred solution of this embodiment, the diameter of the upper port of the water receiving funnel 92 is larger than the diameter of the lower port of the blanking channel 421, and completely covers the lower port of the blanking channel 421 in the vertical projection direction.

[0038] As a preferred solution of this embodiment, the stirrer 43 includes a stirring shaft 431 and a stirring frame 432 installed at the lower end of the stirring shaft 431. A sleeve 433 is also sleeved outside the stirring shaft 431. The stirring shaft 431 and the sleeve 433 are either non-contact or rotatably connected, and there is a cavity channel between them. The upper part of the sleeve 433 extends out of the stirring pot 41 and is connected to a hot air pipe 434. The lower end of the sleeve 433 extends to the lower end of the stirring shaft 431, and a plurality of air inlet holes 4331 are arranged at intervals on the side wall of the sleeve. A temperature sensing probe 435 is also arranged between the stirring shaft 431 and the sleeve 433. The tail end or signal wire of the temperature sensing probe 435 extends out of the stirring pot 41 through an opening on the sleeve 433. An exhaust hole and a filter screen are also arranged on the stirring pot 41, and an exhaust pipe 436 is connected to the outside of the exhaust hole. In this solution, by arranging the sleeve to enclose a cavity channel around the stirring shaft 431 and providing a plurality of air inlet holes 4331 arranged at intervals on the side wall of the sleeve, it is convenient to evenly input hot air into the stirring pot 41 to achieve uniform heating, and it is also convenient to arrange the temperature sensing probe 435 by using the cavity channel. In other embodiments, the hot air pipe may not be provided, and hot air may be directly supplied into the stirring pot 41 through the popcorn feeding pipe 45 connected to the boiler.

[0039] As a preferred solution of this embodiment, it further includes a cup transporting mechanism 8. The cup transporting mechanism 8 can carry the cup and move the cup 100 to the lower part of the pot bottom frame 42 to receive the material falling from the feeding channel 421. The cup transporting mechanism 8 includes a rotating frame 81, a rotating frame motor 82, and a cup holder 83 for supporting the cup 100. The rotating frame motor 82 can drive the rotating frame 81 to rotate around a vertical axis. The cup holder 83 is arranged at one end of the cup frame away from the axis, and a guardrail 831 for preventing the cup 100 from slipping is arranged on the circumference of the cup holder 83. In this solution, by moving the cup 100 through the rotating frame 81, compared with the linear cup transporting mechanism 8, it can easily realize the movement of the cup 100 in the horizontal and vertical spaces inside the popcorn machine, so as to more conveniently match the transporting position of the cup 100 with different devices inside the popcorn machine. It occupies less space, has a simple and stable structure, low failure rate, and is more convenient for accurately positioning the transporting position of the cup body and is not prone to deviation.

[0040] The second object of the present utility model is achieved by the following technical solutions:
