Description

Technical Field

[0001] The utility model relates to the technical field of automatic processing / selling equipment, in particular to a feeding mechanism and a popcorn machine with the same. Background Art

[0002] Many automatic processing and vending equipment for bulk goods (such as popcorn machines, candy bean vending machines, etc.) need to be equipped with a quantitative unloading mechanism. Taking a popcorn machine as an example, the function of the quantitative unloading mechanism is generally to quantitatively output the raw materials (such as corn, etc.) in the silo to the popcorn making device, and then the popcorn making device processes the raw materials into popcorn. However, the automatic vending popcorn machines on the market now generally use a solenoid valve as a quantitative unloading mechanism at the outlet of the silo, and control the quantitative discharge by controlling the opening and closing time of the solenoid valve. However, in actual applications, since the stacking height of the raw materials in the silo will gradually change, the raw material outflow speed will also change when the solenoid valve is opened. Therefore, even if the solenoid valve is opened for the same time, it is difficult to ensure that the discharge amount is the same each time, and it is difficult to achieve stable quantitative discharge. This will make it difficult to keep the amount of popcorn produced each time consistent, affecting the user experience. Utility Model Content

[0031] Embodiment 1:

[0032] like Figure 1-5 As shown, this embodiment provides a feeding mechanism 100, including a silo 1, a turntable 2, a feeding barrel 3, a fixed plate 4 and a driving device 5. The silo 1 is fixedly arranged and has a feeding port 11 at the bottom. The turntable 2 is located below the silo 1 and can rotate under the drive of the driving device 5. The inner cavity volume of the feeding barrel 3 is smaller than that of the silo 1 and both ends thereof are open. The feeding barrel 3 is eccentrically connected to the bottom of the turntable 2 and the turntable 2 is provided with an opening corresponding to the upper port of the feeding barrel 3. The fixed plate 4 is located below the silo 1 and can rotate under the drive of the driving device 5. A discharge port 41 corresponding to the lower port of the lower barrel 3 is provided below and on the barrel 3. The discharge port 41 and the feed port 11 are staggered in the rotation direction of the turntable 2 so that the turntable 2 can carry the lower barrel 3 alternately through the feed port 11 and the discharge port 41 when the turntable 2 rotates, and when the lower barrel 3 passes through the feed port 11, its upper port is connected to the feed port 11 and its lower port is blocked by the fixed plate 4; when the lower barrel 3 passes through the discharge port 41, its lower port is connected to the discharge port 41 and the turntable 2 can block the feed port 11.

[0033] The unloading mechanism provided in this embodiment is generally used in automatic processing / selling equipment for bulk goods (such as automatic popcorn machines, candy bean vending machines, etc.). When working, the turntable 2 is driven to rotate by the driving device 5, which can drive the unloading barrel 3 to alternately pass through the feeding port 11 and the discharging port 41. When the unloading barrel 3 passes through the feeding port 11, the material in the silo 1 can fall into and fill the unloading barrel 3. When the unloading barrel 3 passes through the discharging port 41, the material in the unloading barrel 3 can be discharged through the feeding port 11, so that the material output each time is equal to the inner cavity volume of the distributing barrel, and stable quantitative discharging can be achieved. Moreover, each rotation of the turntable 2 can complete a discharging process. The structural design is compact and ingenious, the operation is stable, and the control is convenient.

[0034] As a preferred solution of this embodiment, at least one side wall of the discharge barrel 3 is provided with a pull-out adjustment frame 6, and the inner cavity volume of the discharge barrel 3 can be adjusted by moving the position of the adjustment frame 6. In this solution, by providing the adjustment frame 6, the inner cavity volume of the discharge barrel 3 can be adjusted as needed, so that the discharge mechanism 100 can not only realize quantitative discharge, but also adjust the quantitative size as needed, and is flexible and convenient to use. As one of the preferred solutions, the adjustment frame 6 includes a partition 61 vertically or obliquely placed in the lower barrel 3, a top plate 62 arranged on the top of the partition 61, extending outward and flat against the bottom of the turntable 2, and a connecting plate 63 arranged on the left and right sides of the partition 61, extending inward and flat against the inner wall of the lower barrel 3. When the adjustment frame 6 moves toward the inside of the lower barrel 3, the top plate 62 can cooperate with the turntable 2 to produce a shielding effect to prevent the material from falling into the lower barrel 3, thereby effectively adjusting the inner cavity volume of the lower barrel 3. The inner wall of the lower barrel 3 and the connecting plate 63 are provided with transverse strip holes 31 and a connecting structure matched therewith, so that the adjustment frame 6 can be moved laterally and the position of the adjustment frame 6 can be locked by screws. In other embodiments, a driving mechanism for driving the adjustment frame to move can also be provided, so as to facilitate the automatic adjustment of the inner cavity volume of the lower barrel by controlling the action of the driving mechanism.

[0035] As a preferred solution of this embodiment, an elastic scraper structure 7 is provided on the lower port of the lower barrel 3 and the lower edge of the feed port 11. In this solution, by providing the elastic scraper structure 7, when the turntable 2 and the feed port 11 move relative to each other, and the lower port of the silo 1 and the fixed plate 4 move relative to each other, the elastic scraper structure 7 can elastically scrape the material without rigidly crushing the material, and can also prevent the material from blocking and stagnating, resulting in poor movement of the turntable 2. Furthermore, the elastic scraper mechanism is preferably a columnar spring arranged laterally, which has a good scraping effect, and the spring itself is a standard part with stable size, easy to replace and low cost.

[0036] As a preferred solution of this embodiment, the silo 1 is a cylindrical structure, and an inclined baffle 12 is installed near the bottom of the silo 1. One side of the baffle 12 is inclined upward and has an arc edge that is in contact with the inner wall of the silo 1. The other side is enclosed with the lower end of the silo 1 to form a feed port 11 and an elastic scraper structure 7 is provided on it. The turntable 2 is a concentric equal-diameter disk arranged directly below the silo 1. A connecting sleeve 8 is also installed above the fixed plate 4. The lower end of the silo 1 is inserted into the connecting sleeve 8 and is detachably fixedly connected thereto. The driving device 5 is a motor fixedly installed below the fixed plate 4. The motor is connected to the turntable 2 through a rotating shaft and can drive the turntable 2 to rotate. In this solution, the silo 1 and the turntable 2 are concentric and equal-diameter circular structures, and the silo 1 is installed on the fixed plate 4 through the connecting sleeve 8, and the turntable 2 is accommodated therein, so that the unloading mechanism 100 is an integrated structure as a whole, which is easy to assemble, and the structural design is ingenious and compact, and the space occupancy is small. When the turntable 2 moves, it will not interfere with external objects.

[0037] As a preferred solution of this embodiment, a touch protrusion 21 is further provided on the lower surface of the turntable 2 near the outer edge, and the unloading mechanism 100 also includes a fixed touch switch 9, and the contact piece of the touch switch 9 is located on the movement path of the touch protrusion 21, so that the touch protrusion 21 can trigger the touch switch 9 when the turntable 2 rotates and passes through the touch switch 9, and when triggered, the unloading barrel 3 is just facing the discharge port 41. In this solution, by providing the touch protrusion 21 and the touch switch 9, it is convenient to automatically control the unloading mechanism 100, so that each time the touch switch 9 is triggered, the driving device 5 stops driving the turntable 2 to rotate, and waits for the next time when the unloading mechanism needs to discharge, and then controls the driving device 5 to start and drive the turntable 2 to rotate one circle to complete unloading and then stop, which is convenient for control.

[0038] As a preferred solution of this embodiment, the upper port size of the lower barrel 3 is smaller than or equal to the feed port 11 and is completely exposed from the feed port 11 when passing through the feed port 11. The lower port size of the lower barrel 3 is smaller than or equal to the discharge port 41 and is completely exposed from the discharge port 41 when passing through the discharge port 41. This design allows the lower barrel 3 to be filled at the fastest speed when passing through the feed port 11, and all the materials in the lower barrel 3 can be discharged at the fastest speed when passing through the discharge port 41.
