Description

Technical Field

[0001] The present invention relates to the technical field of pancake making equipment, in particular to an unmanned pancake selling robot control mechanism. Background Art

[0002] A robot is an intelligent machine capable of semi-autonomous or fully autonomous operation. It can be programmed and automatically controlled to perform tasks such as work or movement. Due to increasing market demand, pancake production has shifted from purely manual to semi-automatic. Using pancake robots to replace manual labor to complete some tasks improves production efficiency and meets market demand. A pancake robot typically consists of a rotating heating plate and a storage tank for pancake batter. The tank discharges the pancake batter onto the heating plate, which heats the pancakes and shapes them into pancakes. Pancake batter is the key ingredient in making pancakes. It is usually composed of flour (wheat flour, corn flour or green flour) dissolved in liquid (such as water, milk or eggs). If there are no customers for a long time, the pancake batter will be left standing for a long time. Due to the large particles and high density of the flour, it will gradually sink to the bottom under the action of gravity, forming a thicker sediment layer, and the upper layer is a thinner water layer. At this time, if the layered pancake batter is directly poured onto the heating plate, it may cause some parts to be too thick and the center is not easy to cook through, or some parts to be too thin and easy to break after frying, affecting the quality of the pancakes, so it needs to be improved.

[0028] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0029] The following is combined with Figures 1-11 This embodiment is described in further detail.

[0030] See also Figure 1-Figure 3 In this embodiment, an unmanned pancake vending robot control mechanism includes a housing 100, a production chamber is provided in the housing 100, a partition 200 is provided at the opening of the production chamber, the partition 200 divides the production chamber into an upper chamber and a lower chamber, a rotatable heating plate 230 is provided in the upper chamber, and a storage tank 220 for storing and discharging pancake batter is also provided in the upper chamber, a detachable side panel 110 is provided at the opening of the production chamber, the side panel 110 is connected to the housing 100 by screws, and a storage tank 220 is provided for storing and discharging pancake batter. A stirring piece is placed to produce precipitation of pancake batter, and a movable spreading component is provided in the upper cavity. The spreading component is close to the heating plate 230 and is used to spread the pancake batter thereon. A discharge port 600 connected to the lower cavity is provided on the partition 200. The movement of the spreading component can also drive the pancake crumbs in the upper cavity to move to the discharge port 600. A movable receiving barrel is provided in the lower cavity, and the receiving barrel moves to the bottom of the discharge port 600 to receive the pancake crumbs. The side panel 110 is installed on the outer shell 100 and is also used to fix the receiving barrel.

[0031] In this embodiment, a discharge pipe 431 communicating with the mixing chamber is provided at the lower end of the storage tank 220, and an openable and closable electromagnetic valve is provided in the discharge pipe 431, and a pressure pump 430 is provided on the top cover. When making pancakes, the electromagnetic valve in the discharge pipe 431 is first opened, and then the pressure pump 430 is started to pressurize the pancake batter in the mixing chamber, so that the pancake batter is discharged from the storage tank 220 through the discharge pipe 431 and falls onto the rotating heating plate 230. The spreading component approaches the heating plate 230 and flattens the pancake batter thereon. After completing the flattening of the pancake batter, the spreading component is moved away from the heating plate 230, and the heating plate 230 heats the pancake batter to make it into pancakes. At this time, the spreading component is again moved close to the heating plate 230, and one end of the pancake is tilted to cooperate with the heating plate The rotation of 230 causes the pancake to separate from the heating plate 230. At this time, the mechanical arm (not shown in the figure) is cooperated with. The mechanical arm is movably provided. The mechanical arm is also provided with a clamping claw for clamping the pancake, which can remove the pancake from the heating plate 230.

A receiving frame is provided in the lower cavity. A take-up door that moves up and down is provided on one side of the receiving frame. Moving the take-up door up can connect the receiving frame to the outside world, making it convenient for customers to take out the pancakes in the receiving frame. The other end of the pancake outlet tube is connected to the receiving frame. When the clamping claw clamps the pancake, the mechanical arm can drive the clamping claw and the pancake to move together and move them to the top of the pancake outlet, so that the pancake passes through the pancake outlet and the pancake outlet tube and is discharged to the receiving frame so that the customer can get the pancake. The stirring component is provided so that when the pancake batter is left to stand for a long time and the flour and water are separated due to gravity, the pancake batter can be stirred to make it evenly mixed again, thereby reducing the impact of uneven texture on the quality of the pancakes. In the process of producing pancakes from pancake batter, when the spreading assembly approaches the heating plate 230, pancake crumbs may be generated. The pancake crumbs will fall off due to the centrifugal force generated by the rotation of the heating plate 230 and eventually fall onto the partition 200. When the spreading assembly moves away from the heating plate 230, the pancake crumbs on the partition 200 will be driven toward the discharge port 600 and eventually fall into the receiving barrel, thereby keeping the partition 200 clean and tidy, and improving the customer's experience. Specifically, an observation window 111 is provided on the side panel 110 corresponding to the upper cavity, so that during the production process of the pancakes, customers can observe the production process of the pancakes in detail, eliminating the customer's concern that the pancakes are pre-made, thereby increasing sales; Among them, through the movable setting of the material receiving barrel, when a certain amount of pancake crumbs are accumulated in the material receiving barrel, the material receiving barrel can be taken out from the lower cavity and the pancake crumbs in the material receiving barrel can be processed centrally.

When the pancake batter is heated, the pancake batter is gradually removed from the heating plate 230. When the pancake batter is heated, the pancake batter is gradually removed from the heating plate 230. When the pancake batter is heated, the pancake batter is gradually removed from the heating plate 230. When the scraper block 1111 is attached to the heating plate 230, the scraper block 1111 is located above the discharge port 600. Some pancake crumbs that have detached from the side wall of the heating plate 230 fall into the receiving barrel, and the remaining pancake crumbs fall onto the partition 200. Specifically, an electric push rod 520 is fixedly connected to the side wall of the upper cavity by bolts, and the output end of the electric push rod 520 is fixedly connected to the push plate 521. When the electric push rod 520 is started, it can drive the push plate 521 to move closer to or away from the heating plate 230.

The movement of the brush 611 is used to drive the pancake crumbs on the partition 200 to move to the discharge port 600.

[0039] In this embodiment, when the connecting rod 610 moves with the electric push rod 520, it can drive the brush 611 to move with it, and then drive the pancake crumbs located on the partition 200 to move with it. When the pancake crumbs move to the discharge port 600, they will eventually fall into the receiving barrel. Specifically, in order to guide the movement of pancake crumbs, a guide bar 510 is provided on the partition 200. The guide bar 510 is arranged obliquely on the partition 200, with one end thereof abutting the side wall of the upper cavity and the other end extending to one side of the discharge port 600. When the brush 611 moves toward the discharge port 600, it can drive the pancake crumbs on the partition 200 to move with it, so that it contacts the guide bar 510 and finally falls to the discharge port 600.
