[0056] Specifically, in this embodiment, the biscuit blocking bar 1221 is disposed close to the side of the flipping wheel 121 containing the biscuits 101, thereby preventing the biscuits 101 in the flipping groove 1211 from falling.

[0057] In addition, in this embodiment, the depth of each of the pancake turning grooves 1211 is set to gradually decrease along the rotation direction of the flipping wheel 121, so that the biscuit 101 is not easy to shake significantly in the accommodating cavity enclosed by the pancake retaining bar 1221 and the flipping wheel 121, thereby ensuring the integrity of the biscuit 101, and further ensuring the accuracy of the flipping assembly 120 in flipping the biscuit 101, thereby improving the efficiency of flipping the biscuit 101.

[0058] It should be noted that the flip assembly 120 further includes a driving member, which is disposed on one side of the flip wheel 121 and the cake storage assembly 110, and is in transmission connection with the flip wheel 121. In this embodiment, the flip wheel 121 is driven to rotate by the driving member.

[0059] Optionally, the driving member is, for example, a motor, and the output shaft of the motor is drivingly connected to the flip wheel 121 . In this embodiment, the flip wheel 121 is driven to rotate by the motor.

[0060] Alternatively, if Figure 2 and Figure 3 As shown, the transport component 130 includes a supporting member 131 and a conveying member 132 .

[0061] The supporting member 131 is disposed on a side of the transporting assembly 130 close to the flipping assembly 120 , and the supporting member 131 is used to receive the biscuits 101 after being flipped over by the flipping assembly 120 .

[0062] Optionally, the supporting member 131 includes a first support bar 1311 and a second support bar 1312, and the first support bar 1311 and the second support bar 1312 are both arranged on the side of the flip wheel 121 away from the pancake trough body 111, and the first support bar 1311 and the second support bar 1312 are relatively arranged on the same horizontal plane.

[0063] It should be noted that there is a gap between the first supporting bar 1311 and the second supporting bar 1312 , and the first supporting bar 1311 and the second supporting bar 1312 jointly support the biscuits 101 that have been turned over.

[0064] Optionally, the conveying member 132 is disposed on a side of the supporting member 131 away from the turning assembly 120 , and the conveying member 132 is used to move the biscuits 101 on the supporting member 131 .

[0065] Alternatively, if Figure 3 As shown, the conveying member 132 includes a push rod 1321 and a transmission chain 1322, the transmission chain 1322 is arranged on the side of the supporting member 131 away from the flip wheel 121, and the push rod 1321 is arranged between the transmission chain 1322 and the supporting member 131, and the push rod 1321 is located between the first support bar 1311 and the second support bar 1312, that is, the push rod 1321 is located in the gap between the first support bar 1311 and the second support bar 1312.

[0066] The push rod 1321 is fixedly mounted on the transmission chain 1322 . In this embodiment, the transmission chain 1322 drives the push rod 1321 to move, and then the push rod 1321 pushes the biscuits 101 on the supporting member 131 to move.

[0067] Optionally, there are multiple push rods 1321 in this embodiment, and the multiple push rods 1321 are arranged at intervals on the transmission chain 1322, and each push rod 1321 pushes one biscuit 101 accordingly.

[0068] Specifically, the specific number of the push rods 1321 in this embodiment is, for example, ten. It should be noted that this embodiment does not limit the specific number of the push rods 1321, and the specific number of the push rods 1321 can be designed according to actual production conditions.

[0069] It should be noted that, in this embodiment, each pancake turning groove 1211 can only hold one biscuit 101. In this embodiment, as the turning wheel 121 rotates, when the second opening 1212 of one pancake turning groove 1211 corresponds to the first opening 1112 of the pancake dropping groove body 111, the multiple biscuits 101 stacked in the pancake dropping groove 1111 of this embodiment enter the multiple pancake turning grooves 1211 in the turning wheel 121 in turn due to their own gravity and the thrust of the other biscuits 101 above.

[0070] Furthermore, the biscuits 101 entering the pancake turning groove 1211 rotate with the flipping wheel 121, and when the pancake turning wheel rotates 180 degrees, the biscuits 101 in the pancake turning groove 1211 are flipped from facing up to facing down, and are conveyed to the biscuit 101 support strip.

[0071] Among them, by matching the linear speed of the push rod 1321 with the flip wheel 121, that is, setting the linear speed of the push rod 1321 to be consistent with the linear speed of the flip wheel 121, one push rod 1321 correspondingly pushes a biscuit 101 on the supporting member 131, and transports it to the bottom of the material shaft of the automatic sandwich machine for biscuit 101 to be coated with cream, and then to other cake dropping mechanisms to cover a biscuit 101 facing up to form a sandwich biscuit 101.
