[0003] The authorized patent with the known application number: CN202110334534.8 discloses a self-service pancake making and selling machine and a pancake manufacturing method. Its background technology proposes the problem that "the batter, sauce, cooking oil, etc. in traditional pancake processing machines are usually sprayed, and quantitative taking cannot be achieved, which is easy to cause pollution to the inside of the machine. Long-term oil mist is not filtered and there are hygiene problems. It is easy to breed bacteria. The inside of the machine cannot be cleaned automatically, and the temperature of the pot cannot be well controlled."

[0019] A method for using an egg liquid blowing device comprises the following steps:

[0020] S1: When in use, the robot arm grabs the sterile raw eggs and places them in the lower sealing bowl, and the egg straightener is used to make the eggs vertically centered. Then, the motor three cooperates with the reducer to drive the rotating support plate to rotate, so that the lower sealing bowl with the eggs placed on it is aligned with the upper sealing bowl. At the same time, the lifting mechanism cooperates with the conical block to drive the striker rod to move up into the connecting pipe. Then, the motor two drives the screw rod two to rotate, so that the connecting block drives the fixed plate and the slider to move down along the guide rail, so that the upper sealing bowl and the lower sealing bowl are closed, and at the same time, the fitting retainer contacts the top of the egg for pre-pressure and fixation. Conversely, when taking out the egg shell, the upper sealing bowl and the lower sealing bowl can be separated by reversing the motor two.

[0021] S2: When the lower sealing bowl switches its position, the lead screw is driven to rotate by a motor, so that the nut seat drives the movable plate to move up along the surface of the guide plate, and at the same time, one end of the torsion spring slides along the surface of the fixed rod, thereby driving the firing pin rod to move up to the inside of the connecting tube, and cooperating with the bracket and the conical block to compress the spring and store force. When egg liquid is added, the movable plate continues to move up, and the movable plate rotates along the inclined surface of the guide plate, and the torsion spring is twisted, so that the movable plate is separated from the bottom of the conical block. At this time, the impact force suddenly released by the spring can drive the firing pin rod to move down and penetrate the eggshell, and then move the movable plate down again. When the movable plate contacts the conical block, it rotates and twists the torsion spring. When it moves to the bottom of the conical block, the torsion spring drives the movable plate to reset and abut against the bottom of the conical block. Then the motor reverses and drives the movable plate to cooperate with the conical block to drive the firing pin rod to move up to the throat, and cooperates with the lip of the throat and the fitting retainer to make the eggshell penetration port in a sealed space, and at the same time, it is convenient to prepare for piercing the eggshell next time.

[0022] S3: When the liquid is discharged, the air is conveyed and pressurized between the upper sealing bowl and the lower sealing bowl through the air pump, the pressurized air pipe and the connecting pipe, so that the egg liquid will be blown to the bottom outlet of the lower sealing bowl by the atmospheric pressure through the sealed space pressure formed by the fitting stabilizer and the throat, thereby achieving the purpose of blowing out the egg liquid. Moreover, since the inside and outside of the eggshell are in the sealed room, only the outlet serves as the sealing medium outlet, so the blowing pressure will not cause pressure on the eggshell, and thus there will be no risk of blowing up the eggshell. In particular, when the eggshell is broken, as long as the bottom of the eggshell is in contact with the bottom sealing pad of the lower sealing bowl intact, the remaining eggshell can still form a seal with the mechanism under the pressure of the fitting retainer, and the purpose of blowing out the egg liquid can still be achieved.

[0023] The working principle and beneficial effects of the present invention are:

[0024] 1. The present invention can close or separate the upper sealing bowl and the lower sealing bowl through the lifting mechanism and the rotating mechanism, and can use the two lower sealing bowls alternately. At the same time, the egg straightener cooperates with the fitting retainer to ensure the egg fixation and sealing effect, facilitate the egg to be fixed and centered, and ensure the sealing effect between the two through the sealing ring, so that the egg is inside the space between the two, which can prevent the egg liquid from being contaminated.

[0025] 2. The present invention drives the screw rod to rotate through a motor, so that the nut seat drives the movable plate to move up along the surface of the guide plate, and at the same time, one end of the torsion spring slides along the surface of the fixed rod, thereby driving the firing pin rod to move up and cooperate with the bracket and the conical block to compress the spring and accumulate force. When the firing pin rod pierces the eggshell, the motor drives the screw rod to drive the movable plate to continue to move up. During the process, the movable plate rotates along the inclined surface of the guide plate, and the torsion spring is twisted, thereby separating the movable plate from the bottom of the conical block. At this time, the impact force suddenly released by the spring can drive the firing pin rod to move down suddenly to penetrate the eggshell, which is convenient and quick to penetrate the eggshell and can ensure the integrity of the eggshell.

[0026] 3. The present invention uses an air pump and a pressurized air pipe to blow air into the connecting pipe to apply pressure, so that the egg liquid in the eggshell will be blown to the bottom outlet of the lower sealing bowl by the atmospheric pressure through the sealed space pressure formed by the fitting stabilizer and the throat, thereby achieving the purpose of blowing out the egg liquid. Therefore, the effect of preparing and using the egg liquid immediately is achieved, avoiding the situation in which the egg liquid is easily deteriorated and contaminated by the method of storing the egg liquid in advance, facilitating the freshness and taste of the egg liquid to the greatest extent, reducing food safety risks, and effectively improving the hygiene, safety and quality of pancakes.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Example

[0039] See also Figure 1 - Figure 8 , the present invention provides an egg taking and egg liquid blowing device for a pancake machine, comprising: a base plate 1, on which a lifting mechanism is provided;

[0040] A fixed plate 2 is arranged on the lifting mechanism, a fixed seat 1 3 is fixedly installed on one side of the fixed plate 2, and a fixed seat 2 4 symmetrically arranged with the fixed seat 1 3 is fixedly installed on one side of the fixed plate 2;

[0041] A connecting pipe 5 is fixedly mounted on the fixing seat 2 4, the bottom end of the connecting pipe 5 is fixedly connected with an upper sealing bowl 6, and a throat 7 is fixedly mounted inside the connecting pipe 5;

[0042] Two lower sealing bowls 8 are arranged below the base plate 1. A rotating mechanism for alternately using the two lower sealing bowls 8 is arranged on the base plate 1. A positioning mechanism for centering the eggs is arranged between the lower sealing bowls 8 and the upper sealing bowl 6.

[0043] A bracket 10 is fixedly mounted on the top of one side of the fixing plate 2, and a firing pin rod 11 is slidably connected to the bracket 10, and the bottom end of the firing pin rod 11 extends into the connecting pipe 5. The bottom end of the firing pin rod 11 is thicker than the rod body. An inverted cone block 13 is fixedly mounted on the surface of the firing pin rod 11, and a spring 12 is sleeved on the surface of the firing pin rod 11, and the two ends are respectively connected to the cone block 13 and the bracket 10;

[0044] A moving mechanism is arranged on the fixed plate 2 for driving the firing pin rod 11 to move up and down so that the spring 12 can store force; and an air supply mechanism is arranged on the fixed plate 2 for blowing air into the connecting pipe 5.

[0045] The positioning mechanism includes a fitting retainer 14 fixedly installed inside the upper sealing bowl 6, an egg straightener 15 fixedly installed inside the lower sealing bowl 8, a sealing groove opened on the surface of the upper sealing bowl 6, and a sealing ring 16 fixedly installed in the sealing groove, wherein the bottom of the lower sealing bowl 8 has a bottom sealing gasket, and the fitting retainer 14 is made of rubber material.

[0046] The technical solution provided by this embodiment is as follows: when in use, the sterile raw egg is grabbed by the mechanical arm and placed in the lower sealing bowl 8, and the egg is vertically centered by the egg straightener 15 to prevent the egg from tilting and affecting the subsequent piercing effect, and then the lower sealing bowl 8 with the egg placed is driven by the rotating mechanism to exchange positions with another empty one, so that the egg is aligned with the upper sealing bowl 6, and at the same time, the moving mechanism cooperates with the conical block 13 to drive the striker rod 11 to move up into the connecting pipe 5 to leave enough space for the egg, and cooperates with the conical block 13 and the bracket 10 to compress the spring 12 to store force, and then the lifting mechanism is used to drive the striker rod 11 to move up into the connecting pipe 5 to leave enough space for the egg, and the spring 12 is compressed and stored by the cone block 13 and the bracket 10. The descending mechanism drives the fixing plate 2 to move downward, so that the fixing plate 2 drives the connecting pipe 5 and the upper sealing bowl 6 to move downward as a whole, and at the same time cooperates with the fitting retainer 14 to contact and pre-press the top of the egg to ensure the fixing and sealing effect, so as to facilitate the egg to be fixed and centered, so that the upper sealing bowl 6 and the lower sealing bowl 8 are closed, and the sealing effect between the two is ensured by the sealing ring 16, so that the egg is in the space between the two, so as to be ready for liquid discharge. When adding egg liquid in the pancake making process, at this time, the moving mechanism cooperates with the conical block 13 to drive the striker rod 11 to move up a short distance again. After moving up to the appropriate position, the moving mechanism separates from the conical block 13. At this time, the spring 12 suddenly releases the restoring force to drive the firing pin rod 11 to move down, so that the egg can be pierced. The moving mechanism then moves down. After moving down to the bottom of the conical block 13, it cooperates with the conical block 13 to drive the firing pin rod 11 to move up to the throat 7. Since the bottom end of the firing pin rod 11 is thicker than the rod body, it cooperates with the lip of the throat 7 and the fitting retainer 14 to make the eggshell penetration hole in a sealed space. At the same time, the air supply mechanism is used to blow air into the connecting pipe 5 to increase pressure, so that the egg liquid will be pressurized by atmospheric pressure through the above The pressure formed in the sealed space is blown to the bottom outlet of the lower sealed bowl 8 to be discharged, thereby achieving the purpose of blowing out the egg liquid, so that the egg liquid is made and used immediately, avoiding the situation that the egg liquid is prone to deterioration and pollution by adopting the method of storing the egg liquid in advance, and ensuring the freshness and taste of the egg liquid to the greatest extent, reducing the hidden danger of food safety, and effectively improving the sanitation, safety and quality of the pancakes. Moreover, since the eggshell inside and outside are in the sealed chamber, only the outlet serves as the sealing medium outlet, so the blowing pressure will not cause pressure on the eggshell, and then there will be no risk of blowing out the eggshell. In particular, when the eggshell is broken, as long as the bottom of the eggshell and the bottom sealing pad contact part of the lower sealed bowl 8 are intact, the remaining eggshell can still form a seal with the mechanism under the pressure of the fitting retainer 14, and the purpose of blowing out the egg liquid can still be achieved.

[0047] Furthermore, the moving mechanism includes a guide plate 17 fixedly mounted on a side surface of the fixed plate 2, a fixed rod 19 fixedly mounted between opposite surfaces of the fixed seat 1 3 and the fixed seat 2 4, a linear component provided on the fixed plate 2, a movable plate 21 provided on the linear component and slidably connected to the guide plate 17, a limit pin rod 22 fixedly mounted on the movable plate 21, and a torsion spring 23 sleeved on the surface of the limit pin rod 22, wherein both ends of the torsion spring 23 are respectively in contact with the fixed rod 19 and the movable plate 21.

[0048] The linear component includes a screw rod 18 rotatably connected between the opposite surfaces of the fixed seat 1 3 and the fixed seat 2 4, a nut seat 20 threadedly connected to the surface of the screw rod 18, and a motor 1 24 fixedly installed on the top of the fixed seat 2 4, the output end of the motor 1 24 movably passes through the fixed seat 2 4 and is connected to the screw rod 18, and the movable plate 21 is rotatably connected to the surface of the nut seat 20.

[0049] Specifically, when driving the firing pin rod 11 to rise and fall to store force, the motor 24 drives the screw rod 18 to rotate, so that the nut seat 20 drives the movable plate 21 to move up along the surface of the guide plate 17, and at the same time, one end of the torsion spring 23 slides along the surface of the fixed rod 19, thereby driving the firing pin rod 11 to move up and cooperate with the bracket 10 and the conical block 13 to compress the spring 12 to store force. When the firing pin rod 11 pierces the eggshell, the motor 24 drives the screw rod 18 to drive the movable plate 21 to continue to move up. During the process, the movable plate 21 rotates along the inclined surface of the guide plate 17, and the torsion spring 23 is twisted, so that the movable plate 21 is separated from the bottom of the conical block 13. At this time, the impact force suddenly released by the spring 12 can drive the firing pin 11 to move up. The needle rod 11 suddenly moves down to penetrate the eggshell, and then the motor 24 cooperates with the screw 18 to drive the movable plate 21 to move down again. When the movable plate 21 contacts the conical block 13, it rotates. When it moves to the bottom of the conical block 13, the torsion spring 23 drives the movable plate 21 to return to the bottom of the conical block 13. Then the motor 24 reverses and drives the movable plate 21 to cooperate with the conical block 13 to drive the firing pin rod 11 to move up to the throat 7. In cooperation with the fitting retainer 14, the eggshell puncture port can be placed in a sealed space, and at the same time, it is convenient to prepare for the next puncture of the eggshell, thereby realizing the role of the firing pin rod 11 in lifting and storing force, which is convenient for quickly penetrating the eggshell and can ensure the integrity of the eggshell so that the subsequent robot arm can grab the eggshell for cleaning.

[0050] Furthermore, the gas delivery mechanism includes an air pump 25 fixedly mounted on a side of the fixed plate 2, and a pressurized air pipe 26 fixedly mounted on the surface of the connecting pipe 5. The output end of the air pump 25 is connected to the pressurized air pipe 26 through pipe 1, and the output end of the air pump 25 is connected to a filter through pipe 2.

[0051] Specifically, after the egg is pierced, since the inside and outside of the egg are both in the sealed space formed between the upper sealing bowl 6 and the lower sealing bowl 8, and the fitting retainer 14, the air pump 25 cooperates with the pressurized air pipe 26 to supply air to the connecting tube 5, thereby pressurizing the space between the upper sealing bowl 6 and the lower sealing bowl 8, so that the egg liquid will be blown out from the bottom of the lower sealing bowl 8 by the atmospheric pressure and the pressure of the sealed space formed by the fitting straightener 14 and the throat 7. At this time, since the inside and outside of the eggshell are both in the sealed space, only the outlet serves as the sealing medium outlet, thereby achieving the effect of blowing out the egg liquid.

[0052] Furthermore, the lifting mechanism includes a guide rail 27 fixedly mounted on the front side of the base plate 1 , a slider 28 slidably connected to the surface of the guide rail 27 , and a power component arranged on the base plate 1 , and the fixed plate 2 is fixedly mounted on the surface of the slider 28 .

[0053] The power component includes a motor 29 fixedly mounted on the top of the rear side of the base plate 1, a screw rod 30 fixedly connected to the output end of the motor 29, and a connecting block 31 threadedly connected to the surface of the screw rod 30. A groove is provided on the base plate 1 for sliding with the connecting block 31, and the connecting block 31 is connected to the fixed plate 2.

[0054] Specifically, when switching the lower sealing bowl 8, the motor 29 drives the screw rod 2 30 to rotate, so that the connecting block 31 moves up, and the connecting block 31 drives the fixed plate 2 and the slider 28 to move up along the surface of the guide rail 27, so that the upper sealing bowl 6 and the lower sealing bowl 8 are separated, and then the position of the lower sealing bowl 8 is switched by the rotating mechanism, and then the motor 29 drives the screw rod 2 30 to reverse, so that the fixed plate 2 moves down, thereby driving the upper sealing bowl 6 and the lower sealing bowl 8 after the switching position to close, so as to achieve the effect of closing the upper sealing bowl 6 and the lower sealing bowl 8.

[0055] Furthermore, the rotating mechanism includes a motor 32 fixedly mounted on the bottom of the rear side of the base plate 1, a mounting frame fixedly mounted on the rear side of the base plate 1 and located below the motor 32, a reducer 33 fixedly mounted on the top of the mounting frame, and a rotating support plate 9 connected to the output end of the reducer 33 through a coupling, the output end of the motor 32 and the input end of the reducer 33 are connected, and two lower sealing bowls 8 are symmetrically fixedly mounted at both ends of the rotating support plate 9.

[0056] Specifically, the motor 32 cooperates with the reducer 33 to drive the rotating support plate 9 to rotate, thereby driving the two lower sealed bowls 8 on the rotating support plate 9 to rotate, so that the two lower sealed bowls 8 can exchange positions, thereby cooperating with the grasping of the robotic arm, so as to achieve the effect of alternating the two lower sealed bowls 8 to hold eggs, thereby accelerating the efficiency of the robotic arm in grasping eggs, and thus improving the work efficiency of pancake making.

[0057] A method for using an egg liquid blowing device comprises the following steps:

[0058] S1: When in use, the robot arm grabs the sterile raw eggs and places them in the lower sealing bowl 8, and the egg straightener 15 makes the eggs vertically centered, and then the motor three 32 cooperates with the reducer 33 to drive the rotating support plate 9 to rotate, so that the lower sealing bowl 8 with the eggs placed is aligned with the upper sealing bowl 6, and at the same time, the lifting mechanism cooperates with the conical block 13 to drive the striker rod 11 to move up to the connecting pipe 5, and then the motor two 29 drives the screw rod two 30 to rotate, so that the connecting block 31 drives the fixed plate 2 and the slider 28 to move down along the guide rail 27, so that the upper sealing bowl 6 and the lower sealing bowl 8 are closed, and at the same time cooperate with the fitting retainer 14 to contact and pre-press and fix the top of the egg. On the contrary, when taking out the egg shell, the upper sealing bowl 6 and the lower sealing bowl 8 can be separated by reversing the motor two 29.

[0059] S2: When the lower sealing bowl 8 switches its position, the motor 24 drives the screw 18 to rotate, so that the nut seat 20 drives the movable plate 21 to move up along the surface of the guide plate 17, and at the same time, one end of the torsion spring 23 slides along the surface of the fixed rod 19, thereby driving the striker rod 11 to move up to the inside of the connecting pipe 5, and cooperates with the bracket 10 and the conical block 13 to compress the spring 12. When the egg liquid is added, the movable plate 21 continues to move up, and the movable plate 21 rotates along the inclined surface of the guide plate 17, and the torsion spring 23 is twisted, so that the movable plate 21 and the bottom of the conical block 13 are Separation, at this time, the impact force suddenly released by the spring 12 can drive the firing pin rod 11 to move down to penetrate the eggshell, and then move the movable plate 21 down again. When the movable plate 21 contacts the conical block 13, it rotates and twists the torsion spring 23. When it moves to the bottom of the conical block 13, the torsion spring 23 drives the movable plate 21 to return to its original position and abut against the bottom of the conical block 13. The rear motor 24 reverses and drives the movable plate 21 to cooperate with the conical block 13 to drive the firing pin rod 11 to move up to the throat 7, and cooperate with the lip of the throat 7 and the fitting retainer 14 to make the eggshell penetration port in a sealed space, while facilitating preparation for piercing the eggshell next time.

[0060] S3: When the liquid is discharged, the air pump 25 cooperates with the pressurized air pipe 26 and the connecting pipe 5 to transmit air and pressurize between the upper sealing bowl 6 and the lower sealing bowl 8, so that the egg liquid will be blown to the bottom outlet of the lower sealing bowl 8 by the atmospheric pressure through the sealed space pressure formed by the fitting straightener and the throat, thereby achieving the purpose of blowing out the egg liquid. Moreover, since the inside and outside of the eggshell are in the sealed room, only the outlet serves as the sealing medium outlet, so the blowing pressure will not cause pressure on the eggshell, and thus there will be no risk of blowing up the eggshell. In particular, when the eggshell is broken, as long as the bottom of the eggshell is in contact with the bottom sealing pad of the lower sealing bowl 8 is intact, the remaining eggshell can still form a seal with the mechanism under the pressure of the fitting retainer 14, and the purpose of blowing out the egg liquid can still be achieved.

[0061] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

9. A method for using an egg liquid blowing device, applicable to an egg taking and egg liquid blowing device for a pancake machine as claimed in any one of claims 1 to 8, characterized in that: The following steps are involved: S1: When in use, the mechanical arm grabs the sterile raw egg and places it in the lower sealing bowl (8), and the egg straightener (15) makes the egg vertically centered, and then the motor three (32) cooperates with the reducer (33) to drive the rotating support plate (9) to rotate, so that the lower sealing bowl (8) with the egg placed is aligned with the upper sealing bowl (6), and at the same time, the lifting mechanism cooperates with the conical block (13) to drive the striker rod (11) to move up into the connecting pipe (5), and then the motor two (29) drives the screw rod two (30) to rotate, so that the connecting block (31) drives the fixing plate (2) and the sliding block (28) to move down along the guide rail (27), so that the upper sealing bowl (6) and the lower sealing bowl (8) are closed, and at the same time, the fitting retainer (14) contacts the top of the egg to pre-press and fix it. On the contrary, when the egg shell is taken out, the motor two (29) is reversed to separate the upper sealing bowl (6) and the lower sealing bowl (8). S2: When the lower sealing bowl (8) switches its position, the motor (24) drives the screw (18) to rotate, so that the nut seat (20) drives the movable plate (21) to move up along the surface of the guide plate (17), and at the same time, one end of the torsion spring (23) slides along the surface of the fixed rod (19), thereby driving the striker rod (11) to move up to the inside of the connecting tube (5), and cooperates with the bracket (10) and the conical block (13) to compress the spring (12) to store force. When the egg liquid is added, the movable plate (21) continues to move up, and the movable plate (21) rotates along the inclined surface of the guide plate (17), and the torsion spring (23) is twisted, so that the movable plate (21) and the conical block (13) are connected. The bottom is separated, and the impact force suddenly released by the spring (12) can drive the firing pin rod (11) to move downward to penetrate the eggshell, and then the movable plate (21) is moved downward again. When the movable plate (21) contacts the conical block (13), it rotates and twists the torsion spring (23). When it moves to the bottom of the conical block (13), the torsion spring (23) drives the movable plate (21) to return to contact with the bottom of the conical block (13). After that, the motor 1 (24) reverses and drives the movable plate (21) to cooperate with the conical block (13) to drive the firing pin rod (11) to move upward to the throat (7), and cooperates with the lip of the throat (7) and the fitting retainer (14) to make the eggshell penetration port in a sealed space, and at the same time, it is convenient to prepare for piercing the eggshell next time. S3: When the liquid is discharged, the air pump (25) cooperates with the pressurized air pipe (26) and the connecting pipe (5) to transmit air and pressurize between the upper sealing bowl (6) and the lower sealing bowl (8), so that the egg liquid can be blown to the bottom outlet of the lower sealing bowl (8) by the atmospheric pressure through the sealed space pressure formed by the fitting straightener (14) and the throat (7), thereby achieving the purpose of blowing out the egg liquid. Since the inside and outside of the eggshell are in the sealed room, only the outlet serves as the sealing medium outlet, so the blowing pressure will not cause pressure on the eggshell, and thus there will be no risk of blowing up the eggshell. In particular, when the eggshell is broken, as long as the bottom of the eggshell and the bottom sealing pad contacting the lower sealing bowl (8) are intact, the remaining eggshell can still form a seal with the mechanism under the pressure of the fitting retainer (14), and the purpose of blowing out the egg liquid can still be achieved.
