[0018] The following clearly and completely describes the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention.

[0019] The present invention provides an automatic egg cracking machine, which includes two egg holders 2 and two egg opening knives 1 arranged symmetrically, the egg holders 2 have an opening facing upward and form an egg groove, the egg opening knife 1 hits the egg from the side to crack it, and a push rod 23 is provided behind the egg holder 2, which synchronously opens at least one side of the egg opening knife 1 to open the egg; in the present invention, by providing the egg opening knife 1 to open the egg from the side, the egg opening knife 1 does not block the egg liquid from flowing out from the side of the egg shell, avoiding the waste of egg liquid; by providing the egg groove with an opening facing upward, when opening the egg from the side, the egg does not fly out from above the opening but remains within the opening, avoiding the need for an additional egg fixing device.

[0020] It should be noted that the egg opening knife 1 in the present invention can be triggered by a mechanical structure to crack the egg, or can be driven by a driving mechanism such as a cylinder or an electromagnetic valve to crack the egg. In the embodiment of the present invention, the egg cracking is triggered by a mechanical structure, which is specifically as follows:

[0021] As shown in FIG. 2-FIG. 6, the egg opening knife 1 in the embodiment of the present invention includes a left blade 12, a right blade 11, a slider 13, and a fixed bracket 3 for mounting the slider 13. The left blade 12 is fixed to the slider 13 via a left knife connecting member 122, and the right blade 11 is fixed to the slider 13 via a right knife connecting member 112. The left blade 12 and the right blade 11 are slidably mounted in the chute 31 above the fixed bracket 3 via the slider 13. A locking component is provided on the slider 13. An energy storage device 5 is provided at the end close to the locking direction (lock groove 1321) of the side of the slider 13, and a reset trigger rod 131 is provided at the other end. An egg knife elastic member 15 is provided between the left knife connecting member 122 and the right knife connecting member 112. In this embodiment, the energy storage device 5 uses a spring. When the locking component is in a locking state, the spring is compressed to generate stored energy, as shown in FIG. 5, the spring is located in the chute 31, one end of the spring abuts against the inner wall of the chute 31, and the other end abuts against the slider 13. The compressed stored energy of the spring causes the slider 13 to generate an impact force towards the end close to the blade. The locking component locks the position of the slider 13, so that the slider 13 is fixed and cannot move. After the locking component is triggered to unlock, as shown in FIG. 6, the compression of the spring unfolds and releases the stored energy to the slider 13, which converts the stored energy of the spring into an impact force moving towards one end of the blade. At this time, the slider 13 slides the blade in the chute 31 and causes the blade to collide with the egg in front, thereby achieving the effect of breaking the egg.

[0022] It should be noted that the locking component in the present invention can be controlled to lock and unlock using various forms such as motor drive or mechanical trigger. In this embodiment, the locking component uses a mechanical structure. Specifically, the locking component includes a slide engaging block 132 that is protruded upward from the slider 13. A lock groove 1321 is provided on the side of the slide engaging block 132. The slide engaging block 132 is provided with a slide hook 14 that is used by engaging with the lock groove 1321. The slide hook 14 uses a trigger structure, one end of which is used to hook and fix the lock groove 1321 of the slide engaging block 132, and the other end of which is provided with an egg-crack trigger rod 142. The middle part is connected to an axis pin so that both ends can rotate. 5 to 6, when the egg-cracking trigger rod 142 is triggered to move, the slide hook 14 rotates along the pivot pin 141 by a certain angle, causing the slide hook 14 to leave the lock groove 1321, thereby releasing the lock on the slider 13; it should be noted that the fixed bracket 3 further includes a hollow upper cover plate 6, the slide engaging block 132 protrudes from the hollow portion of the upper cover plate 6, and the pivot pin 141 for fixing the pivot point of the slide hook 14 is fixed to the upper cover plate 6, so that the upper cover plate 6 can fix the position of the pivot pin 141, prevent dust from falling, and provide protection for the mechanical structure below the upper cover plate 6.

[0023] As shown in FIG. 7, the egg holder 2 in the embodiment of the present invention includes a left egg holder block 22 and a right egg holder block 21. When the left egg holder block 22 and the right egg holder block 21 are arranged side by side and approach each other, an egg groove for placing eggs is formed with the opening facing upward. The push rod 23 is a double-rod type push rod. The push rod 23 is fixedly provided below the fixed bracket 3. Left egg holder connection members 221 and right egg holder connection members 211 are provided on both sides of the push rod 23. An egg holder trigger rod 231 is provided at one end of the push rod 23. An egg holder elastic member 24 is provided between the left egg holder connection member 221 and the right egg holder connection member 211. The push rod 23 controls the opening of the left egg holder block 22 and the right egg holder block 21, and the egg holder elastic member 24 controls the automatic closing of the left egg holder block 22 and the right egg holder block 21. By providing the lower cover plate 7, the push rod 23 is fixedly provided below the fixed bracket 3. The push rod 23 can use a triangular double-rod structure or a structure with a push block. In this embodiment, the push rod 23 uses a double-rod structure, and the angle between the double rods can change as the push rod 23 moves. One end of the main body rod of the push rod 23 is configured as a trigger type structure, that is, one end of the main body rod of the push rod 23 is the egg holder trigger rod 231. The left egg holder connection member 221 and the right egg holder connection member 211 are fixedly connected to the double rods of the push rod 23 respectively, that is, they are located on both sides of the push rod 23. As shown in FIG. 8, when the egg holder trigger rod 231 is triggered and displaced in the direction of the egg, the push rod 23 is displaced in the same direction. The opening and closing angle between the double rods changes from α to β, and the distance between the ends of the double rods changes from a to b. It is clearly understood that α < β and a < b. Since the ends of the double rods are fixedly provided on the left egg holder connection member 221 and the right egg holder connection member 211 respectively, as the egg holder trigger rod 231 is triggered and displaced in the direction of the egg, the push rod 23 pushes the left egg holder connection member 221 and the right egg holder connection member 211 to move away from each other.Furthermore, the left egg holder block 22 and the right egg holder block 21 can be separated to both sides, so that the egg liquid can flow out after breaking the egg shell and drop into a frying pan or other egg liquid collecting device.

[0024] It should be noted that the egg opening knife 1 in the present invention can only achieve the function of cracking an egg through the action of the energy storage device 5 and the locking component, that is, it can only make the left blade 12 and the right blade 11 collide with the egg to break the shell. At this time, the left blade 12 and the right blade 11 are in a closed state, and in order to separate the left blade 12 and the right blade 11 from each other and open the egg shell to allow the egg liquid to flow out, the left knife connecting member 122 and the right knife connecting member 112 are controlled by a motor to separate from each other, or the egg holder 2 is opened to synchronously control the egg opening knife 1 locked in the egg to open, thereby allowing the egg liquid to flow out. In this embodiment, a structural design is used in which the egg opening knife 1 and the egg holder 2 open synchronously.

[0025] Specifically, as shown in FIG. 9 and FIG. 10, in the embodiment of the present invention, the upper end of the left egg holder connecting member 221 is provided with a left guide block 222 with a slope, the lower end of the left knife connecting member 122 is provided with a left bump 121 extending downward, the upper end of the right egg holder connecting member 211 is provided with a right guide block 212 with a slope as well, and the lower end of the right knife connecting member 112 is provided with a right bump 111 extending downward. In the present embodiment, both the left guide block 222 and the right guide block 212 use a trapezoidal structure, and the left bump 121 and the right bump 111 In order to better introduce the left blade 12 into the non-slope portion along the trapezoidal slope of the left guide block 222 and the right guide block 212, a trapezoidal structure is provided, and the left guide block 222, the right guide block 212, the left bump 121 and the right bump 111 are all symmetrically provided. When the egg opening knife 1 is released and locked and jumps out toward the egg by the energy storage device 5, before the stored energy of the energy storage device 5 is completely consumed, the egg knife elastic member 15 is pulled between the right knife connecting member 112 and the left knife connecting member 122, so that the left blade 12 and The right blade 11 and the left knife connecting member 122 are constantly pulled by force to approach each other and stick to each other, and then collide with the egg synchronously to crack the eggshell. At this time, the state of the left knife connecting member 122, the right knife connecting member 112, the left egg holder connecting member 221 and the right egg holder connecting member 211 is shown in FIG. 9, the left knife connecting member 122 and the right knife connecting member 112 are in a parallel relationship with each other, and then the energy storage device 5 continues to provide stored energy so that the left blade 12 and the right blade 11 can be inserted further deeper into the egg. At this time, the left blade 12 and the right blade 11 can only crack the egg. When push rod 23 pushes left knife connecting member 122 and right knife connecting member 112 to separate to both sides, left bump 121 is moved by left guide block 222, and at the same time, right bump 111 is moved by right guide block 212, so that left bump 121 and right bump 111 are separated to both sides. At this time, the state of left knife connecting member 122, right knife connecting member 112, left egg holder connecting member 221 and right egg holder connecting member 211 is as shown in FIG. 10, and there is a certain angle between left knife connecting member 122 and right knife connecting member 112,The angle between the ends close to the left blade 12 and the right blade 11 is large, so that the left egg holder connecting member 221 connected to the left bump 121 and the right egg holder connecting member 211 connected to the right bump 111 actually move to both sides synchronously, and further move the left blade 12 and the right blade 11 to both sides, thereby achieving the effect that the left blade 12 and the right blade 11 open the cracked egg shell and let the egg liquid flow out.

[0026] It should be further explained that in some embodiments, when the egg holder 2 and the egg opening knife 1 are opened, one part may move separately and another part may be fixed and not move; or in other embodiments, the two parts may move to both sides at the same time to achieve the separate opening; specifically, for example, the left egg holder block 22 and the left blade 12 may remain stationary, and the right egg holder block 21 and the right blade 11 may move to the open side by driving a motor, while the right egg holder block 21 and the right blade 11 may remain stationary, and the left egg holder block 22 and the left blade 12 may move in the egg opening direction by driving a motor; or in the above embodiments, a symmetrical guide structure may be used, which allows the symmetrically arranged egg holder 2 and egg opening knife 1 to move to both sides along the symmetrical center to achieve the opening and closing movement of the egg holder 2 and the egg opening knife 1.

[0027] The automatic egg cracking machine in the embodiment of the present invention is driven by a driving device 8 to slide as a whole, the driving device 8 in this embodiment uses a ball screw and a motor, and while driving, it uses a trigger mechanism 4 to control the egg cracking operation, the egg opening knife 1 is opened by the egg holder 2, thereby realizing the egg opening operation, and after the egg liquid flows out, the egg opening knife 1 is automatically reset (hereinafter abbreviated as reset) and the egg holder 2 automatically discards the egg shell (hereinafter abbreviated as shell discard) operations are further set, and these operations are automatically performed by moving the machine with the trigger mechanism 4, thereby making the egg cracking operation fully automated. The trigger mechanism 4 includes an egg cracking trigger part 41, a reset trigger part 42 and an egg holder trigger part 43, and the egg holder trigger part 43 includes a part of the trigger structure required for opening eggs. Specifically, the push rod 23 can be displaced a short distance toward the egg, that is, the egg holder trigger rod 231 at one end of the push rod 23 contacts the first inclined surface of the egg holder trigger part 43 and climbs along the first inclined surface, thereby displacing the push rod 23 toward the egg. The following describes the overall operating steps of the automatic egg cracking machine in this embodiment of the present invention.

[0028] 2 to 11, the egg holder 2 is located at one end of the trigger mechanism 4, and immediately after placing the delivered egg in the egg groove, the driving device 8 starts to move the egg cracking machine along the egg cracking direction. First, the egg cracking trigger rod 142 acts with the egg cracking trigger part 41. When the egg cracking trigger rod 142 is triggered and moves, the slide hook 14 is rotated by a certain angle along the axis pin 141, and the slide hook 14 is released from the lock groove 1321, thereby releasing the lock on the slider 13. The slider 13 causes the left blade 12 and the right blade 11 to collide with the egg and crack it by the energy storage device 5, and the left blade 12 and the right blade 11 are locked in the egg while remaining in the closed state. Then, the egg holder trigger rod 231 comes into contact with the egg holder trigger part 43, and the egg holder trigger part 43, the first slope of the egg holder 22 is climbed, and the push rod 23 is displaced toward the egg, and the push rod 23 pushes the left egg holder block 22 and the right egg holder block 21 to separate, and the separation distance is small enough that the egg shell does not fall from the egg holder 2, and the left bump 121 and the right bump 111 of the egg opening knife 1 are respectively engaged with the left guide block 222 and the right guide block 212 at this time, so that when the left guide block 222 and the right guide block 212 move away from each other, the left blade 12 and the right blade 11 are moved away from each other, and the egg shell is opened from the opening opened at the egg cracking position, and the egg liquid in the egg shell flows down between the left blade 12 and the right blade 11, and falls through the gap between the opened left egg holder 2 and the right egg holder 2 to perform egg scrambling or egg liquid collection.

[0029] After that, the driving device 8 continues to move the egg cracking device along the egg cracking direction, and after the egg cracking trigger rod 142 is released from the egg cracking trigger part 41, the slide hook 14 returns to the lock angle along the axis pin 141. However, the slider 13 is not reset at this time, and when it continues to move in the egg cracking direction to the reset trigger part 42, the reset trigger rod 131 climbs along the slope of the reset trigger part 42 in the direction away from the egg, so that the reset trigger rod 131 is pushed by the reset trigger part 42 in the direction away from the egg, thereby pulling out the egg opening knife 1 from inside the eggshell, and the left bump 121 and the right bump are respectively pushed by the left guide block. The left and right guide blocks 222 and 212 are separated, and are re-attached by the action of the egg knife elastic member 15. When the slider 13 comes into contact with the slide hook 14, the slide hook 14 slides again into the lock groove 1321 and locks. Then the driving device 8 continues to move the egg cracker along the egg cracking direction, and moves it to the position for triggering the egg holder trigger part 43 to discard the shell, that is, to the second inclined surface of the egg holder trigger part 43. The push rod 23 is further pushed toward the egg by the egg holder trigger part 43, which causes the left egg holder block 22 and the right egg holder block 21 to be separated further, and the egg shell falls through both gaps and is discarded. Finally, the egg holder 2 is located at the other end of the trigger mechanism 4, and the driving device 8 moves the egg cracker in the opposite direction along the return direction, and the egg holder elastic member 24 is provided between the left egg holder connecting member 221 and the right egg holder connecting member 211, and the egg holder elastic member 24 pulls the left egg holder connecting member 221 and the right egg holder connecting member 211 so as to tend to keep them approaching each other, and when the egg holder trigger rod 231 at one end of the push rod 23 moves in the return direction along the egg holder trigger portion 43, the left egg holder connecting member 221 and the right egg holder connecting member The pushing force on 211 gradually decreases until it is completely gone, and the egg holder elastic member 24 pulls the left egg holder connecting member 221 and the right egg holder connecting member 211 to gradually reset them, and finally the egg cracker returns to the position where it originally received the egg, i.e. completing one cycle of automatic egg cracking, and sliding the egg cracker by one driving device 8, completing all the operations of egg cracking, egg opening, resetting and shell discarding in one go, with its ingenious structure, which saves the internal space of the small machine and increases the space utilization rate, making it suitable for use in small machines with small installation space.
