[0034] like Figure 1 As shown, the utility model proposes a coin-operated quantitative ice cream machine, including a shell 1, a coin sensing mechanism 2 installed on one side of the shell 1 for coin insertion, and a discharge component 6 realizes the discharge of ice cream after the coin is started. The coin sensing mechanism 2 is a prior art and will not be described in detail here.

[0035] For details, please refer to Figure 2The above-mentioned ice cream machine includes a production system for producing ice cream arranged in a housing 1, and the production system includes a mixing mechanism 3, a refrigeration mechanism 4, and a feeding mechanism 5. The mixing mechanism 3 for mixing raw materials includes a mixing cylinder 31, a first servo motor 32, a mixing rod 33, and a mixing blade 34. The mixing cylinder 31 is arranged at the top of the housing 1, and the mixing cylinder 31 is convenient for adding raw materials. The first servo motor 32 is installed at the bottom of the mixing cylinder 31, and the output end of the first servo motor 32 penetrates the mixing cylinder 31 and is fixedly connected with the mixing rod 33. After the first servo motor 32 is started, it drives the mixing rod 33 to rotate. Multiple groups of mixing blades 34 are installed on the outer ring of the mixing rod 33, and the mixing blades 34 rotate synchronously with the mixing rod 33 to mix the raw materials. The refrigeration mechanism 4 for refrigeration includes a refrigeration cylinder 41, a compressor 42, and a condenser 43. The hollow refrigeration cylinder 41 is fixedly installed in the housing 1. The refrigeration cylinder 41 and the mixing cylinder 31 are connected by a pipeline and controlled by a solenoid valve. After the solenoid valve is opened, the raw materials in the mixing cylinder 31 flow into the refrigeration cylinder 41. The compressor 42 is installed in the shell 1, and the condenser 43 is installed on the inner side of the shell 1. The side wall of the refrigeration cylinder 41 has a refrigeration cavity, which contains refrigeration liquid. The refrigeration cavity of the refrigeration cylinder 41, the compressor 42, and the condenser 43 are connected in sequence by copper pipes, which are used to refrigerate the inside of the refrigeration cylinder 41 to reduce the temperature of the ice cream and make it shape. The condenser 43 dissipates heat, and the refrigeration cylinder 41 absorbs heat to form a closed loop, and the temperature is transferred through the refrigerant as a medium. The feeding mechanism 5 for feeding includes a second servo motor 51, a stirring rod 52, a stirring barrel 53, and blades 54. The second servo motor 51 is installed on the side of the refrigeration cylinder 41 away from the discharge component 6. The output end of the second servo motor 51 passes through one side of the refrigeration cylinder 41 and is fixedly connected to the stirring rod 52. The second servo motor 51 drives the stirring rod 52 to rotate after starting. The stirring barrel 53 is installed on the outer ring of the stirring rod 52, and the stirring barrel 53 rotates synchronously with the stirring rod 52. The spirally arranged blades 54 are installed on the outer ring of the stirring barrel 53. The blades 54 rotate synchronously with the stirring barrel 53 to stir the cooled ice cream raw materials so that they are cooled evenly, thereby facilitating the production of ice cream. At the same time, when the refrigeration cylinder 41 is connected to the discharge hole 62, the setting of the blades 54 allows the ice cream to enter the discharge hole 62 and be discharged from below the discharge hole 62.

[0036] Further, such as Figure 3As shown, the above-mentioned ice cream machine also includes a discharge assembly 6 installed on the side of the shell 1 for cooperating with the feeding mechanism 5 to realize discharge. The discharge assembly 6 includes a fixed block 61, a discharge hole 62, a valve stem 63, and a first push rod motor 64. The fixed block 61 is installed on the side of the shell 1, and the position of the fixed block 61 is fixed. A discharge hole 62 is opened in the fixed block 61, and the discharge hole 62 is connected to the inside of the refrigeration cylinder 41. The valve stem 63 is slidably connected to the discharge hole 62. When the valve stem 63 slides, it controls whether the refrigeration cylinder 41 is connected to the discharge hole 62. The output end of the first push rod motor 64 installed in the shell 1 is fixedly connected to the valve stem 63. The first push rod motor 64 is used to drive the movement of the valve stem 63 after starting.

[0037] For further information, see Figure 1 The ice cream machine further includes a receiving mechanism 7 for receiving materials, which is arranged below the discharge assembly 6. The receiving mechanism 7 includes a linear motor 71, a lifting rod 72, and a snap ring 73. The linear motor 71 is installed in the housing 1. The lifting rod 72 is fixedly connected to the side of the moving end of the linear motor 71 close to the fixed block 61. The snap ring 73 is installed at the end of the lifting rod 72 away from the linear motor 71. After the linear motor 71 is started, the lifting rod 72 drives the snap ring 73 to move, thereby driving the egg tray placed in the snap ring 73 to move and approach the discharge assembly 6, so as to facilitate catching the ice cream.

[0038] In this embodiment, when in use, raw materials are put into the mixing cylinder 31, and the first servo motor 32 is started to drive the mixing blade 34 to rotate to stir and mix the raw materials, and then the solenoid valve is opened, and the raw materials in the mixing cylinder 31 flow into the refrigeration cylinder 41. At this time, the compressor 42 and the condenser 43 are started, driving the refrigerant to circulate and move, and refrigerating the refrigeration cylinder 41. At this time, the temperature in the refrigeration cylinder 41 gradually decreases, so that the raw materials therein are formed. At the same time, the second servo motor 51 is started, and the stirring barrel 53 and the blade 54 are driven to rotate through the stirring rod 52. At this time, the blade 54 turns the ice cream in the refrigeration cylinder 41, so that the temperature is evenly dispersed, and the overall shape difference is small, so that the ice cream is formed. When it is necessary to discharge, first place an egg tray in the clamp ring 73, and then insert coins into the coin sensing mechanism 2. When the amount is reached, the first push rod motor 64 is started to drive the valve stem 63 to move upward. At this time, the valve stem 63 slides upward in the discharge hole 62, so that the refrigeration cylinder 41 is now connected to the discharge hole 62. At this time, the blade 54 continues to rotate to bring the ice cream into the discharge hole 62, and discharges it from the bottom of the discharge hole 62. At the same time, the linear motor 71 starts to drive the clamping ring 73 to move upward through the lifting rod 72, so that the egg tray moves upward and close to the fixed block 61. At this time, the ice cream just enters the egg tray when it is discharged, and as the ice cream is discharged, the linear motor 71 drives the egg tray to move slowly downward, thereby completing the production of an ice cream. At this time, since the control time of the first push rod motor 64 can be accurately controlled, the discharge amount of ice cream is quantitative, preventing the discharge of excess ice cream from causing waste. Embodiment 2

[0039] like Figure 4 As shown, based on the first embodiment, the ice cream machine further includes a protective assembly 8 for catching the melted ice cream liquid, the protective assembly 8 includes a liquid collecting cup 81, a connecting plate 82, a connecting rod 83, and a second push rod motor 84. The liquid collecting cup 81 is arranged below the discharge hole 62. The liquid collecting cup 81 is used to catch the liquid of the melted ice cream remaining after the discharge at the discharge hole 62. At the same time, the bottom of the liquid collecting cup 81 can also be connected to a pipeline for connecting to a waste liquid bucket. The bottom of the liquid collecting cup 81 is fixedly connected to a connecting plate 82, and the liquid collecting cup 81 drives the connecting plate 82 to move synchronously when it moves. The top of the connecting plate 82 away from the end of the liquid collecting cup 81 is also fixedly connected to a connecting rod 83, and the connecting rod 83 drives the liquid collecting cup 81 to move synchronously through the connecting plate 82 when it moves. The output end of the second push rod motor 84 installed on the side of the housing 1 is rotatably connected to the end of the connecting rod 83 away from the connecting plate 82. The protection component 8 also includes a third servo motor 85, a synchronization rod 86, a first gear 87, a second gear 88, and a rotating sleeve 89. The third servo motor 85 arranged on one side of the second push rod motor 84 is also installed on the housing 1. The output end of the third servo motor 85 is fixedly connected to the synchronization rod 86. The end of the synchronization rod 86 away from the third servo motor 85 is installed with the first gear 87. After the third servo motor 85 is started, the first gear 87 is driven to rotate by the synchronization rod 86. A second gear 88 meshing with the first gear 87 is arranged on one side of the first gear 87. When the first gear 87 rotates, it drives the second gear 88 to rotate synchronously. The rotating sleeve 89 is fixedly connected to the second gear 88, and the second gear 88 rotates synchronously with the rotating sleeve 89. The rotating sleeve 89 is slidably mounted on the connecting rod 83, and is used to drive the connecting rod 83 to slide in the rotating sleeve 89 after the second push rod motor 84 is started. At the same time, the connecting rod 83 is in a quadrangular prism shape, so that the rotating sleeve 89 can drive the connecting rod 83 to rotate synchronously when rotating. The rotating sleeve 89 is installed on the side of the housing 1 through two sets of bearing seats, so that the position of the rotating sleeve 89 is fixed.

[0040] In this embodiment, when discharging, the second push rod motor 84 is started to drive the connecting rod 83 to move downward, and the connecting rod 83 slides in the rotating sleeve 89, and the connecting rod 83 drives the liquid collecting cup 81 to move downward through the connecting plate 82. Then the third servo motor 85 is started, and after starting, the third servo motor 85 drives the first gear 87 to rotate through the synchronous rod 86. When the first gear 87 rotates, it meshes with the first gear 87 and the second gear 88 rotates synchronously, and at the same time drives the rotating sleeve 89 to keep rotating in place under the limiting action of the bearing seat. At this time, the rotating sleeve 89 drives the connecting rod 83 to rotate synchronously, and when the connecting rod 83 rotates, it drives the liquid collecting cup 81 to move away from the bottom of the discharge hole 62 through the connecting plate 82, so as to facilitate the discharge operation. After the discharge is completed, the third servo motor 85 is started to rotate in the opposite direction to drive the liquid collecting cup 81 to move to the bottom of the discharge hole 62, and then the second push rod motor 84 is started to move the liquid collecting cup 81 upward for sealing. At this time, the ice cream remaining at the bottom of the discharge hole 62 will melt, drip into the liquid collecting cup 81 after melting, and can flow into the waste liquid barrel along the pipeline, thereby preventing the dripping ice cream from contaminating the equipment.
