Description

Technical Field

[0001] This utility model relates to the technical field of mooncake processing equipment, and more specifically, to an automatic pastry machine. Background Technology

[0002] Automatic puff pastry machines typically consist of two rollers, one above the other, with an adjustable distance between them. The dough is placed between the rollers, and the rotation and pressure of the rollers thin the dough. The operator then folds the thinned dough, repeating this process multiple times to create multi-layered puff pastry. The principle of the puff pastry machine is based on the extensibility of dough and the layered structure after folding. By thinning the dough, its surface area is increased, and fats such as butter are added between the layers, thus enhancing the crispness.

[0003] Existing automatic dough extrusion machines compress the dough, requiring pastry chefs to fold and adjust it during operation. This process requires continuous operation by the chefs, increasing labor costs. However, if the folding is done entirely automatically, the mechanical folding of the dough cannot be adjusted to the feel of the dough after folding, resulting in a poor texture in the final product. Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic puff pastry machine.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: The automatic dough sheeter includes a dough sheeter body, on which a conveyor belt for conveying dough is provided.

One end of the rotating rod is fixedly connected to the receiving plate, and the other end of the rotating rod is controlled by a reciprocating motor. The driving of the reciprocating motor and the sliding of the conveyor belt are both controlled by the control system on the dough sheeter body.

[0006] The present invention is further configured such that: two distance measuring instruments are provided on the fixed frame, the two distance measuring instruments are respectively placed above the receiving plate and above the conveyor belt, the two distance measuring instruments are close to each other and overlap the measuring edges and are located at the junction of the receiving plate and the conveyor belt, and the distance measuring instruments are wirelessly connected to the control system of the puffing machine.

[0008] The present invention is further configured such that: a blocking rod is fixedly connected to the other end of the support frame, and the receiving plate abuts against the blocking rod when it rotates to overlap the support frame.

[0009] The present invention is further configured such that: a flexible plate is fixedly connected to one end of the receiving plate near the conveyor belt, the flexible plate having elastic deformation properties, and the other side of the flexible plate abutting against the end face of the conveyor belt.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] This automatic puff pastry machine, such as Figures 1-3As shown, the machine includes a dough sheeter body 1, on which a conveyor belt 2 is installed for conveying dough. The kneaded dough is placed on the conveyor belt 2 of the dough sheeter body 1. The conveyor belt 2 is a reciprocating conveyor belt 2. The dough is squeezed by the pressure rollers on the dough sheeter body 1 and repeatedly folded to achieve the purpose of dough sheet forming. After squeezing, a folding mechanism is set at one end of the dough sheeter body 1 near the conveyor belt 2. The folding mechanism includes a receiving plate 3 and a rotating rod 4. One end of the rotating rod 4 is fixedly connected to the receiving plate 3, and the other end of the rotating rod 4 is controlled by a reciprocating motor. When the dough is conveyed from the conveyor belt 2 to the receiving plate 3, the reciprocating motor drives the receiving plate 3 to flip through the rotating rod 4. Part of the dough is placed on the conveyor belt 2 and the other part is placed on the receiving plate 3. After the receiving plate 3 flips, it drives the dough to fold. After folding, the dough will move towards the pressure rollers on the dough sheeter body 1 under the drive of the conveyor belt 2. This process is repeated many times to complete the dough sheet squeezing and forming process.

[0020] The reciprocating motor drive and the sliding of the conveyor belt 2 are both controlled by the control system on the puff pastry machine body 1. Two distance measuring instruments 8 are installed on the fixed frame 6. The two distance measuring instruments 8 are respectively placed above the receiving plate 3 and above the conveyor belt 2. The two distance measuring instruments 8 are close to each other, with the measuring edges overlapping and located at the junction of the receiving plate 3 and the conveyor belt 2. The distance measuring instruments 8 are wirelessly connected to the control system of the puff pastry machine body 1. In order to ensure that the folding mechanism can fold the dough more evenly and improve the automation of the folding mechanism on the puff pastry machine body 1, a recognition device has been added.

[0021] The measuring instrument 8 can be a camera or other device capable of identifying objects. After taking a picture, the measuring instrument 8 transmits it to the control system of the puff pastry machine 1. The current wireless transmission technology is also very mature and can fully meet the usage requirements. The control system compares the signals transmitted by the two measuring instruments 8. When the dough lengths captured by the two measuring instruments 8 are consistent, the control system of the puff pastry machine 1 releases a signal, the conveyor belt 2 stops conveying to one end of the folding mechanism, and the reciprocating motor is started to drive the receiving plate 3 to flip, folding the dough on the receiving plate 3 and the dough on the conveyor belt 2. After folding, the reciprocating motor drives the receiving plate 3 to flip in the opposite direction, and the conveyor belt 2 is conveyed away from the folding mechanism for the next pressing. After the flipping is completed, the reciprocating motor and the drive of the conveyor belt 2 are not set with trigger signals. Only the start interval time of the reciprocating motor is set in the control system to simplify the trigger signal, thereby reducing the occurrence of error in the release of the trigger signal and ensuring the stable folding of the dough.

[0022] A support frame 5 is welded onto the puff pastry machine body 1. A reciprocating motor is fixed to the side wall of the support frame 5 by bolts. A connecting rod is integrally formed at the end of the rotating rod 4 away from the receiving plate 3. The connecting rod is rotatably connected to the support frame 5. The axis of the connecting rod is perpendicular to the axis of the rotating rod 4. The connecting rod is connected to the rotor of the reciprocating motor. The overall cross-sectional shape of the rotating rod 4 and the connecting rod is L-shaped. A through slot is provided on the support frame 5. The connecting rod is inserted into the through slot and passes through the through slot, which facilitates the reciprocating motor on the support frame 5 to control the connecting rod. After the connecting rod rotates, it drives the rotating rod 4 to rotate. The two symmetrically arranged rotating rods 4 have snap-fit ​​slots on their side walls that are close to each other. The receiving plate 3 is snapped and fixed in the snap-fit ​​slot to form a detachable connection, which makes it easy to remove the receiving plate 3 for cleaning and improves the practicality of the puff pastry machine body 1.

[0023] A blocking rod is fixedly connected to the other end of the support frame 5. When the receiving plate 3 rotates to overlap the support frame 5, it abuts against the blocking rod. A flexible plate is fixedly connected to one end of the receiving plate 3 near the conveyor belt 2. The flexible plate has elastic deformation properties. The other side of the flexible plate abuts against the end face of the conveyor belt 2. The flexible plate is made of food-grade deformable plastic sheet. There is a height difference between the receiving plate 3 and the conveyor belt 2. The receiving plate 3 is set at an angle between the receiving plate 3 and the conveyor belt 2, so that the dough conveyed on the conveyor belt 2 can be conveyed to the receiving plate 3 along the guide of the flexible plate. At the same time, the flexible plate can deform. When the receiving plate 3 rotates and folds the dough, it will squeeze the flexible plate to deform, reducing rigid collisions during the use of the pastry machine and extending the service life of the pastry machine.

[0024] A fixed frame 6 is welded to one end of the support frame 5 near the conveyor belt 2. A counting plate 7 is rotatably connected to the fixed frame 6. A counter is set on the fixed frame 6 to count the number of rotations of the counting plate 7 and respond accordingly. Existing automated counters are also commonly used, and an appropriate one can be selected. The height of the fixed frame 6 is greater than the height of the receiving plate 3, and the length of the counting plate 7 is greater than the thickness of the fixed frame 6. The rotation axis of the counting plate 7 is located at the center line of the counting plate 7. The reciprocating motor drives the receiving plate 3 to rotate. When the receiving plate 3 completes one fold towards the conveyor belt 2, it pushes the counting plate 7 to rotate counterclockwise once, and the counter counts once. When the receiving plate 3 resets, it pushes the counting plate 7 to rotate clockwise once, and the counter does not count. After accumulating a certain number of counts, a response is triggered to remind the operator to shape or adjust the dough. The specific number of responses can be adjusted according to the actual product needs to ensure that the production needs of various pastries are met.

[0025] Working principle: First, the kneaded dough is placed on the conveyor belt 2 of the puff pastry machine 1. As the conveyor belt 2 transports the dough to the folding structure, two rangefinders 8 transmit the captured information in real time to the control system of the puff pastry machine 1. When the lengths of the dough on the receiving plate 3 and the conveyor belt 2 are approximately the same, the conveyor belt 2 is paused, and the reciprocating motor is started to drive the receiving plate 3 to rotate via the connecting rod and the rotating rod 4. The dough also completes the folding process. After folding, the reciprocating motor rotates in the opposite direction, and the conveyor belt 2 slides in the same direction, driving the folded dough to be conveyed and pressed. This cycle is repeated to achieve automated folding. During folding, the receiving plate 3 pushes the counting plate 7 on the fixed frame 6 to count. The counter retains the count and responds to remind the operator to shape or perform other operations on the dough after a certain number of counts are reached.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
