Technical Field

[0001] This utility model relates to the field of food processing, specifically to an automatic pancake machine. Background Technology

[0002] Jianbing guozi is one of China's traditional famous snacks. The traditional way of making jianbing is to pour batter onto a jianbing griddle, spread it out manually, and cook the batter into a pancake.

All of these processes are done manually, which is slow, time-consuming, labor-intensive, and inefficient, and cannot meet market demand. Therefore, to improve the production efficiency and output of jianbing, an automatic jianbing machine is needed. Utility Model Content

Detailed Implementation

[0043] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0044] Figure 1 and Figure 2 The diagram shows the structure of an automatic pancake machine in one embodiment, including: a base plate 1, a support base 2, a cylinder 3, a connecting arm 4, a motor 5, a floating joint 6, a connector 7, a mounting base 8, a scraper 9, a pancake griddle 10, and a clamp 11.

[0045] The base plate 1 is located at the bottom of the entire machine; the pancake griddle 10 is fixed on the base plate; the support base 2 is fixed on the base plate and located on one side of the pancake griddle 10; the cylinder 3 is installed on the support base, with the telescopic end of the cylinder 3 pointing vertically upward; one end of the connecting arm 4 is fixedly connected to the telescopic end of the cylinder 3, and the other end is suspended above the center of the pancake griddle 10; the motor 5 is fixed to the end of the connecting arm 4 suspended above the pancake griddle 10; the clamp 11 is locked around the output shaft of the motor 5; the floating joint 6 is connected to the clamp 11; the mounting base 8 is connected below the floating joint 6; the scraper 9 is installed at the mounting base 8; and the connector connects the clamp 11 and the mounting base 8.

[0046] The automatic pancake machine in the above embodiments can automatically and quickly spread the batter evenly and heat it into pancakes. It has a fast processing speed, high production efficiency, and greatly increases pancake output.

[0047] In a preferred embodiment, a preferred structure for the support base is provided, such as... Figure 1 As shown, the support base 2 includes an L-shaped plate and a right-angled triangular plate. One side of the L-shaped plate is attached to and fixed to the base plate, while the other side is perpendicular to the base plate; the two right-angled sides of the right-angled triangular plate are attached to and fixed to the two sides of the L-shaped plate, respectively. This structural design makes the connection between the support base and the base plate more secure.

[0048] In a preferred embodiment, a preferred structure for the connecting arm 4 is provided, such as... Figure 1 and Figure 2 As shown, connecting arm 4 has an L-shaped structure. In some specific embodiments, a motor mount can also be provided at the end of the connecting arm for mounting the motor.

[0049] During motor rotation, eccentricity is inevitable, causing additional forces and affecting the uniformity of rotation. In a preferred embodiment, such as... Figure 3 As shown, the clamp 11 is a cylindrical structure, divided into two pieces (first clamp piece 111 and second clamp piece 112), which are fixed to the output shaft of the motor by nuts. A protrusion is provided at the bottom of the first clamp piece 111 for fixing to the floating joint.

[0050] like Figure 4 As shown, the floating connector 6 consists of two parts: a floating housing 61 and a ball joint 62. The housing 61 has a spherical cavity 611 inside and an output port 612. One end of the ball joint 62 is a ball 621, and the other end is a rod 622. The ball 621 is located inside the spherical cavity 611 of the housing 61, and the rod 622 extends out of the output port 612 and is fixed to the mounting base 8.

[0051] There is no axial gap between the connector housing and the ball joint; there is a radial gap between the rod body and the output port.

[0052] In some specific embodiments, the floating shell 61 is provided with an internal thread, which, along with a nut, is used to fix the protrusion of the aforementioned clamp. The rod body 622 is provided with an external thread, which, along with a nut, is used to fix the fixing seat 8.

[0053] In this embodiment, the floating connector used is a standard component, with a movable connection between its ball head and the connector housing, allowing the ball head to swing freely within the output range, thereby achieving the floating function. This design ensures that the scraper can completely adhere to the surface of the pancake griddle during descent, avoiding the problem of the scraper not fully adhering to the surface of the pancake griddle, and thus preventing uneven thickness of the pancakes.

[0054] Of course, since the floating joint has a ball joint inside, it cannot transmit the rotational force of the motor. In a preferred embodiment, connector 7 is designed to transmit the rotational force of the motor, allowing the scraper to rotate. Specifically, as shown... Figure 5 As shown, the connector 7 includes an upper fixing plate 71, a lower fixing plate 72, and a connecting rod 73. The upper fixing plate 71 is an L-shaped plate and is fixed to the clamp 11 by bolts.

[0055] The lower fixing plate 62 is an L-shaped plate, which is fixed to the mounting base 8 by bolts; the two ends of the connecting rod 73 are connected to the upper fixing plate 71 and the lower fixing plate 72 respectively.

[0056] Furthermore, to ensure the floating effect, in a preferred embodiment, the upper and lower fixing plates are respectively provided with through holes, the connecting rod extends into the through holes, and is locked in place using a nut; the diameter of the through hole is larger than the diameter of the connecting rod, so that the connecting rod can sway when inserted into the through hole, so that the floating is not affected.

[0057] In a preferred embodiment, the mounting base 8 is a cylinder with a missing corner at the bottom, forming an L-shaped surface. The scraper is fixed to the L-shaped surface.

[0058] In a preferred embodiment, the bottom edge of the scraper that contacts the batter is designed with a concave structure. Specifically, the concave edge of the scraper's bottom maintains a fixed distance from the surface of the pancake griddle, which is equivalent to the thickness of a pancake. Without this concave structure, the scraper would be completely pressed against the pancake griddle, causing the batter to be unable to spread smoothly and ultimately being scraped off completely.

[0059] In another preferred embodiment, a control board for cylinders and motors can also be used, which is connected to the Raspberry Pi to achieve automation.

[0060] In one specific embodiment, taking the automatic pancake machine in the above embodiment as an example, the entire operation process is provided:

[0061] When adding batter, the pancake griddle is raised to avoid obstruction: Activate cylinder 3, cylinder 3 rises, driving connecting arm 4 to rise, thereby driving motor 5, floating joint 6, mounting base 8 and scraper 9 to rise simultaneously. At this time, batter is added to the pancake griddle 10.

[0062] When processing batter, the batter is lowered and positioned: the control cylinder 3 lowers, and the same transmission process as the rising process lowers the entire structure including the motor 5, floating joint 6, mounting base 8, and scraper 9, so that the scraper comes into contact with the batter.

[0063] During the pancake spreading stage: The floating joint 6 ensures that the scraper 9 is in complete contact with the pancake griddle 10. The motor 5 is started, which drives the connecting piece 7 through the clamp 11, thereby driving the scraper 9 to rotate and quickly and evenly spread the batter for heating.

[0064] In addition, the entire system is connected and controlled via a Raspberry Pi, which is extremely low-cost and automates the process.

[0065] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the substantive content of this utility model.
