Background technique

Vending machine is a common equipment for commercial automation. It is not limited by time and place, can save manpower and facilitate transactions. It is a brand-new form of commercial retail, also known as a 24-hour micro supermarket. At present, there are four types of common vending machines: beverage vending machines, food vending machines, integrated vending machines, and cosmetic vending machines. Among them, the food vending machine includes a cotton candy machine, and a cotton candy preparation device is arranged inside the machine. The semi-automatic or fully automatic marshmallow machines currently on the market greatly reduce labor costs. However, there are still the following problems:

First of all, because the production of marshmallows requires a high-speed rotating high-temperature burner, the power mechanism of the high-speed rotating burner designed by the existing automatic cotton candy machine generally adopts a belt drive to transmit power. For example, a DC motor uses a synchronous pulley to drive the furnace. When the head rotates, it has the following defects: ① The transmission is slippery, the speed change ratio is inaccurate, the overall size is large, the life of the timing belt is short, and the timing belt needs to be replaced frequently, which is time-consuming and laborious, and is not suitable for flammable and explosive occasions; ② For The force of the shaft and the bearing is large, and the transmission efficiency is low, and when the power mechanism used is a DC brush motor, the friction between the brush and the commutator will cause sparks, the noise is large, it is easy to generate heat, and the interference is large. High temperature operation leads to certain potential safety hazards; ③ It is difficult to maintain, and the brushes need to be replaced constantly, which is time-consuming and laborious, and requires a lot of human resources to be managed, resulting in high use costs.

Secondly, its core component is the burner module for processing marshmallows. The burner module must be kept clean to ensure the machine's life and long-lasting work. In the current cotton candy vending machine, the cleaning of the burner module needs to be manually cleaned after being disassembled regularly, which is time-consuming and labor-intensive, and is inconvenient to use.

In addition, in the process of making marshmallows, the stove head module needs to be kept at a high temperature to ensure that the candy canes are evenly thrown out. However, the current automatic marshmallow machine cannot achieve rapid heating of the stove head module, and requires a long wait, which reduces the production efficiency of marshmallows.

Correspondingly, referring to FIG. 1 , the air pump assembly 300 further includes a bifurcated pipe 302 and a second pipe 304 , one end of the bifurcated pipe 302 is communicated with the air pump 301 , and the other end is divided into two parts, which are respectively connected to the air pump 301 . The first pipeline 303 and the second pipeline 304 communicate with each other. In addition, the burner module 100 further includes a collection structure 60 , the collection structure 60 is disposed on the sugar outlet pipe 20 and is close to the hollow shaft brushless motor 81 , but is not connected to the hollow shaft 30 . Specifically, the collection structure 60 is provided with an air outlet 63 and an air outlet pipe 64, two ends of the air outlet pipe 64 are respectively connected to the second pipe 304 and the air outlet (63), and the air outlet 63 is located in the Below the backflow gap 121 , the airflow in the air pump 301 can reach the backflow prevention gap 121 through the air outlet pipe 64 and the air outlet pipe 63 .

In the above design, a backflow prevention gap 121 is provided between the sugar outlet pipe 40 and the hollow rotating shaft 30, and the hollow rotating shaft 30 drives the burner main body 10 and the burner cover 20 to rotate, so the outlet The sugar tube 30 is not affected by the rotation of the burner main body 10, and the anti-backflow gap 121 can ensure that the hollow shaft 30 will not rub against the sugar outlet tube 40 during operation to generate noise. The anti-backflow gap 121 is located above the collection structure 60, and the airflow through the air outlet 63 on the collecting device 60 reaches the anti-backflow gap 121, so that the material in the sugar-making chamber 11 is under the action of the airflow. It will not enter the anti-backflow gap 121 , so no waste will be generated, and at the same time, it will be ensured that the sugar outlet pipe 40 and the hollow shaft 30 will not be damaged by the waste. At the same time, the sugar outlet pipe 30 and the air outlet 63 are connected to the same air pump 301, which can ensure that the air pressure at the anti-backflow gap 121 is approximately the same as the air pressure blown by the sugar outlet pipe 30, and no large air pressure will be generated. Therefore, the normal operation of the furnace head module 100 will not be affected.

Further, the collecting structure 60 further includes a collecting groove 61 , a second through hole 62 , a connecting head 65 and a fixing seat 66 . The collection structure 60 is sleeved on the sugar outlet pipe 40 through the second through hole 62 and fixed by the fixing seat 66 to prevent the collection structure 60 from sliding on the sugar outlet pipe 40 . The air outlet 63 is provided in the collecting tank 61 , and the connecting head 65 is used to connect the air outlet pipe 64 to the air outlet 63 to prevent air leakage.

In another embodiment, the sugar outlet pipe ( 40 ) is provided with a shielding portion 42 near the first through hole ( 12 ), and the shielding portion 42 is located above the backflow prevention gap 121 . After the air pump 301 transports the sugar-making raw materials into the sugar-making chamber 11 through the air flow of the first pipe 303, the sugar-making raw materials may hit the burner cover due to inertia or the power provided by the air flow. , so that the sugar raw material rebounds to the direction of the sugar outlet pipe 40 . By arranging the shielding portion 42, the rebounded sugar-making raw material can be prevented from entering the sugar-discharging pipe 40, which can avoid blocking the backflow prevention gap 121 and improve the utilization rate of the sugar-making raw material.

Preferably, a sliding bearing (not shown) is provided at the anti-backflow gap 121 between the sugar outlet pipe 40 and the hollow rotating shaft 30, which can effectively prevent the sugar outlet pipe 40 from being bent and directly abrading the hollow rotating shaft. 30.

The above are only some embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the principles of the present invention, several improvements and modifications can be made. It should be regarded as the protection scope of the present invention.
