Description

Technical Field

[0001] The utility model relates to the technical field of automated food processing and selling equipment, in particular to an automatic feeding refrigerated cabinet, an automatic feeding system and an automatic grilled sausage vending machine. Background Art

[0002] Grilled sausage is a very popular snack food. Grilled sausages sold on the market are basically processed by grilling machines. Traditional grilling machines require manual operation. They need to manually put the sausages on the grill for grilling, manually judge whether the grilled sausages are baked, and manually take out the baked sausages. The labor cost is high and the efficiency is low. The manual operation process will also increase the risk of food contamination. In order to solve the above problems, the Chinese utility model patent with announcement number CN210295282U discloses a mechanical arm and an automatic grilling sausage system, a vending system, and a vending machine. The basic principle is that the mechanical arm takes out the skewered sausages from the low-temperature storage room and transfers them to the baking room. When the sausages are baked, the mechanical arm transfers the sausages for shipment. The low-temperature storage chamber in the patent is provided with a storage box for storing sausages. The storage box is set on the door body. When in use, it is moved out of the box body following the pushing and pulling of the door body for the robotic arm to take out the sausages. It can be seen that each time the material is taken out, the storage box and the sausages therein will be in contact with a large amount of outside air, which is not conducive to maintaining a low temperature in the storage chamber, will increase the energy consumption of the low-temperature storage chamber, and will increase the risk of food contamination; moreover, since the sausages are statically placed in the storage box, the robotic arm needs to move to a different position to take the material each time the material is taken out, which places high requirements on the robotic arm and the control system, and will increase the manufacturing and maintenance costs.

[0018] 1. The refrigerator is equipped with several independent automatic silos. Each silo has a built-in feeding mechanism, which can automatically transport materials (such as sausages) to the discharge port. When taking materials, the taking mechanism only needs to drive the taking bracket to move to the front of the corresponding silo and then squeeze the discharge baffle to take out a single sausage, making the taking mechanism and the taking process simpler, more stable, and more efficient, with low manufacturing and maintenance costs.

The structural design is simple and ingenious. The XZ plane moving frame is vertically arranged in front of the refrigerator, so that the space occupied by the XZ plane moving frame and the refrigerator in the width direction (X-axis direction) and the height direction (Z-axis direction) overlap, and the space occupied in the cabinet in the depth direction (Y-axis direction) is also small, so that the space utilization rate in the cabinet can be higher. The overall structural layout of the sausage vending machine is more compact and occupies less space. Moreover, the material-retrieving bracket can be driven by the XZ plane moving frame to move arbitrarily within the XZ plane range, with a large range of activity and better structural strength and stability.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0033] The automatic feeding refrigerator 1 provided in this embodiment is generally installed in an automatic food processing and vending machine. Taking an automatic grilled sausage vending machine as an example, when in use, the raw sausages (materials) are placed in advance on the feeding mechanisms 13 of the automatic silos 12 in the refrigerator 1 for refrigeration. After receiving the order information from the consumer, the controller will control the refrigerator 1 to open the refrigerator door 11, and control the feeding mechanism 13 to convey the front sausage to the unloading port to wait for unloading. The refrigerator door 11 does not need to be fully opened, but only needs to be opened until the material taking mechanism of the vending machine can move to the unloading baffle 15 of the corresponding silo 12 and push the unloading baffle 15 to retract backwards, so that the single sausage at the feeding port can fall out to the material taking mechanism. After the material taking is completed, the refrigerator door 11 is controlled to be closed. Compared with the prior art, the refrigerator 1 of the present invention is provided with a plurality of independent automatic silos 12, each of which is equipped with a feeding mechanism 13, which can automatically feed the sausages to the discharge port. When taking materials, the feeding mechanism only needs to drive the feeding bracket to move to the front of the corresponding silo 12 and then squeeze the discharge baffle 15 to take out a single sausage, so that the feeding mechanism and the feeding process are simpler, more stable and more efficient, with low manufacturing and maintenance costs. Moreover, when taking materials, it is not necessary to pull out all the silos 12 and all the sausages therein. During the taking process, the refrigerator 1 has less heat exchange with the outside world, making the refrigerator 1 more energy-efficient. Moreover, the feeding motor 14 of the automatic silo 12 is located outside the refrigerator 1, and there are no electrical components in the refrigerator 1, which can improve the reliability and durability of the equipment.

The feeding motors 14 corresponding to the two silos 12 located on the outermost sides are respectively The driving roller 132 which is arranged on the left and right outer walls of the refrigerator 1 and directly connected to the corresponding conveyor belt 131 through its driving shaft can move the conveyor belt 131 forward and backward. The other silos 12 located between the outermost silos 12 have a first gear 133 extending from the end of their corresponding driving roller 132. The driving shaft of the corresponding feeding motor 14 passes through the upper and lower layers of the conveyor belt 131 of the outermost silo 12 and is provided with a second gear 134 at the end. The first gear 133 and the second gear 134 are meshed, so that the conveyor belt 131 of the silo 12 can be driven to move forward and backward. This solution realizes that when there are three or more silos 12, the feeding mechanisms 13 of the middle silo 12 and the outermost silo 12 can be independently controlled and driven without interfering with each other, and the structural design is reasonable and ingenious.

[0035] As a preferred solution of this embodiment, the automatic door opening mechanism 16 includes a door opening motor 161 and a door opening slide rail 162 fixedly connected to the outer wall of the refrigerator 1, and a door opening push rod 163 slidably connected to the door opening slide rail 162. The output shaft of the door opening motor 161 is transmission-connected to the door opening push rod 163 via a door opening transmission belt 164. The front end of the door opening push rod 163 is tilted upward and a roller protrudes from the inner side of the front end. The roller abuts against the refrigerator door 11. The rotation of the door opening motor 161 can drive the door opening push rod 163 to move along the direction of the door opening slide rail 162, thereby driving the refrigerator door 11 to open and close.
