[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] refer to Figures 1 to 7This invention provides a puff pastry imitation handmade filling production line. The production line includes: a feeding conveyor line 1, a transferring mechanism 2, a dough pressing assembly 4, a filling assembly 5, and a filling assembly 6 arranged sequentially along the processing direction of the production line. The dough blanks pass sequentially through the transferring mechanism 2, the dough pressing assembly 4, and the filling assembly 5 via the feeding conveyor line 1 to form dough workpieces with filling, which are then conveyed to the filling assembly 6. The dough blanks are conveyed via the feeding conveyor line 1, first to the transferring mechanism 2, which transfers them to the filling conveyor line 8. The filling conveyor line 8 then sequentially conveys the dough blanks to the dough pressing assembly 4, the filling assembly 5, and the filling assembly 6. The dough pressing assembly 4 shapes the dough into a specified shape. Subsequently, the filling assembly 5 adds filling to the dough, forming dough workpieces with filling. Finally, the dough workpieces are conveyed to the filling assembly 6 for the filling operation.

[0034] The filling assembly 6 includes a lifting receiving unit that moves vertically and a horizontal filling unit that opens and closes horizontally. The lifting movement path of the lifting receiving unit intersects with the horizontal movement path of the horizontal filling unit.

[0035] The dough product moves with the lifting and supporting unit, and the filling operation is completed based on the convergence of the lifting and supporting unit and the horizontal filling unit. The lifting and supporting unit moves vertically to support and lift the filled dough to a predetermined height. The horizontal filling unit opens and closes horizontally to form a wrapping space. The movement paths of these two units intersect in space, ensuring precise triggering of the wrapping action.

[0036] The specific working process is as follows: The filled dough workpiece is conveyed to the lifting and receiving unit. The lifting and receiving unit begins to descend, moving the dough workpiece towards the horizontal filling unit. Simultaneously, the horizontal filling unit begins its horizontal opening and closing motion. When the lifting and receiving unit descends to the designated position, the opening and closing motion of the horizontal filling unit creates a wrapping space and covers the dough workpiece, allowing the dough workpiece to complete the filling operation under the coordinated action of the lifting and receiving unit and the horizontal filling unit.

[0037] This design replaces manual operation with mechanical coordination, maintaining the shaping characteristics of hand-wrapping filling while achieving automated continuous production. The key is the intersecting motion paths of the lifting receiving unit and the horizontal filling unit, ensuring precise triggering of the wrapping action and mimicking the three-dimensional trajectory of hand-wrapping filling. The formation of this dynamic wrapping area solves the coordination problem between the filling action and workpiece positioning, improving the accuracy and efficiency of filling.

[0038] Specifically, the material transfer mechanism 2 includes: a gantry frame disposed above the feeding conveyor line 1, an arc-shaped track disposed on the gantry frame, and a transfer manipulator slidably engaged with the arc-shaped track. A material transfer drive motor is disposed inside the gantry frame. The transfer manipulator engages with the arc-shaped track based on a movable swing arm. The material transfer drive motor drives and connects to the movable swing arm, causing the movable swing arm to swing along the arc-shaped track. The transfer manipulator slidably engages with the limiting groove of the movable swing arm, allowing the transfer manipulator to move horizontally as the movable swing arm swings.

[0039] Furthermore, the transplanting robot is equipped with a vertical guide rail slider mechanism and a horizontal guide rail slider mechanism, which enable the transplanting robot to adaptively adjust with the swinging motion of the movable arm to meet the lifting and translation requirements after the surface blank is gripped.

[0040] Furthermore, the transplanting robot can be configured as a cylinder-driven clamping robot structure or a motor-driven clamping robot structure, and the clamping pressure of the clamping robot meets the clamping requirements of the dough blank. These details will not be elaborated here.

[0041] The production line also includes one or more filling conveyor lines 8. The movement trajectory of the transfer robot covers the feeding conveyor line 1 and the filling conveyor line 8. Based on the transfer robot clamping and transporting the dough blanks of the feeding conveyor line 1, the dough blanks can be processed separately, so that the feeding conveyor line 1 can simultaneously meet the feeding needs of multiple filling conveyor lines 8, thereby improving the processing efficiency.

[0042] Specifically, the pressing assembly 4 includes: a first driving component, a first gear transmission mechanism, and a plurality of tapered pressing rods 632;

[0043] The first driving component is connected to the first gear transmission mechanism. Several conical pressure rods 632 are evenly distributed along the circumference and are connected via the first gear transmission mechanism. When the pressing assembly 4 is running, the first driving component drives the main shaft of the first gear transmission mechanism to rotate, which in turn drives each conical pressure rod 632 to rotate synchronously around its own axis through gear meshing. When the tapered ends of the conical pressure rods 632 contact the dough blank, they gradually apply radial pressure as they rotate. Their tapered design ensures that the pressure decreases from the center to the periphery, preventing tearing of the dough edges due to sudden pressure changes. Multiple conical pressure rods 632 evenly distributed along the circumference form a ring-shaped pressing area. As the dough blank passes through, each pressure rod 632 sequentially presses its surface at multiple angles, simulating the spiral pressing trajectory of hand-rolling. Because the first gear transmission mechanism ensures that the rotational speed and phase of all pressure rods 632 are consistent, the number of times the dough is pressed and the pressure value tend to be balanced in each area, thereby eliminating local thickness differences. After pressing, the tapered pressure bar 632 gradually reduces the contact area between its tapered end and the dough, allowing the dough to detach naturally from the surface of the pressure bar 632 and preventing adhesion that could damage the dough. This technical solution, through synchronous transmission and structural optimization, improves pressing efficiency while achieving uniform dough thickness and completely eliminates the hygiene risks associated with manual operation.

[0044] Specifically, the production line also includes a dough extrusion assembly 3, which includes a first screw conveyor 31 and a first output pipe 32. The first screw conveyor 31 is used to knead and convey the dough, and convey it to the conveyor belt of the filling conveyor line 8 through the first output pipe 32.

[0045] The first screw conveyor 31 is located outside the conveyor belt of the filling conveyor line 8. The first output pipe 32 is connected to the first screw conveyor 31, and the outlet of the first output pipe 32 is located above the filling conveyor line 8. A cutting mechanism 33 is provided between the first output pipe 32 and the filling conveyor line 8. The cutting mechanism 33 is provided with a first linkage transmission mechanism and a plurality of cutting blades 332 distributed along the circumference. The plurality of cutting blades 332 are driven by gear meshing, and the gear of one of the cutting blades 332 is connected to the first linkage transmission mechanism, so that the first transmission linkage mechanism 331 can drive the plurality of cutting blades 332 to open and close, thereby realizing the cutting operation of the dough output from the first output pipe 32 and realizing the quantitative output of the dough.

[0046] The dough extrusion assembly 3 is located at the front end of the dough pressing assembly 4. By setting the dough extrusion assembly 3, the types of dough materials that can be fed into the filling conveyor line 8 can be enriched, so that the filling conveyor line 8 can meet the processing needs of different types of products.

[0047] Specifically, the filling assembly 5 includes a second screw conveyor and a second output pipe. The second screw conveyor is located outside the conveyor belt of the filling conveyor line 8, and the second output pipe is connected to the second screw conveyor, with the outlet of the second output pipe located above the filling conveyor line 8. The structural design and working principle of the filling assembly 5 are the same as those of the dough extrusion assembly, and will not be described in detail here.

[0048] Specifically, a telescopic adjustment mechanism 7 is provided at the end of the filling conveyor line 8. The telescopic adjustment mechanism 7 includes a third drive component 71 and an S-shaped movable component 72. The conveyor belt of the filling conveyor line 8 covers the surface of the S-shaped movable component 72, and the third drive component 71 drives the S-shaped movable component 72 to telescopically move. The third drive component 71 includes a third drive motor 711 and a synchronous belt 712. The third drive component 71 is located on the outside of the filling conveyor line 8, and the synchronous belt 712 is connected to the S-shaped movable component 72 based on a connecting shaft, so that the third drive motor 711 can drive the S-shaped movable component 72 to telescopically move.

[0049] Specifically, the S-shaped movable component 72 includes: a staggered support plate 721 and a movable shaft 722. The movable shaft 722 is connected to one end of the support plate 721 based on a connecting rod 723. The support plate 721 and the movable shaft 722 are driven to extend and retract horizontally based on the third drive component 71 and the synchronous belt 712.

[0050] Specifically, the S-shaped movable component 72 further includes a fixed rotating shaft 724, which is staggered with the movable rotating shaft 722, and an S-shaped path is formed between the fixed rotating shaft 724, the movable rotating shaft 722 and the receiving plate 721, and the conveyor belt of the filling conveyor line 8 is arranged along the S-shaped path;

[0051] The S-shaped path is dynamically adjusted in position by the third driving component 71, the conveyor belt of the filling conveyor line 8 moves with the S-shaped path, and the conveyor belt is kept taut by the cooperation of the fixed rotating shaft 724 and the movable rotating shaft 722.

[0052] When the third drive component 71 is activated, the synchronous belt 712 is driven to rotate, which in turn drives the movable shaft 722 and the receiving plate 721 to move horizontally via the connecting rod. At this time, the fixed shaft 724 remains in a fixed position, while the movable shaft 722 moves with the receiving plate 721, causing the length ratio of different path segments formed by the S-shaped path to change. The conveyor belt is stretched between the fixed shaft 724 and the movable shaft 722. The difference in path curvature caused by their staggered arrangement creates a tension gradient on the surface of the conveyor belt, which meets the conveying requirements of the filling conveyor line 8 and allows for the change of the position of the end of the conveyor belt, so that the dough blanks with filling can be transported to the vertical lifting support unit of the filling assembly 6.

[0053] Specifically, the vertical lifting support unit is equipped with a material transfer conveyor belt, which is used to transfer processed products and realize the discharge and conveying of products. Above the vertical lifting support unit is a pressure bar unit 63, which includes a pressing drive motor 631 and a pressure bar 632. The pressing drive motor 631 drives the pressure bar 632 based on a synchronous action belt mechanism. When the vertical lifting support unit descends to a preset position, the pressing drive motor 631 drives the pressure bar 632 to descend and press and shape the processed product, thereby improving the processing quality of the filling production.

[0054] The horizontal filling unit includes: a transmission gear located in the middle, several action plates arranged in a circumferential direction, and several action gears. The several action gears mesh with the transmission gear, and the several action plates are connected one-to-one to the several action gears.

[0055] One of the actuating gears is connected to an external power component via a transmission linkage mechanism, allowing the actuating gear to rotate under the drive of the external power component. Several actuating plates deflect horizontally along with the driven gear, achieving the closing and opening / closing actions. The rotational motion of the driven gear is decomposed into multiple actuating gears through meshing transmission, with the rotation angle of each actuating gear maintaining a strict correspondence with the input angle of the driven gear. Driven by the actuating gears, the actuating plates deflect horizontally with the same angular velocity and phase difference, forming a centripetal closing or centrifugal opening action pattern. During the closing phase, the ends of all actuating plates move simultaneously towards the central axis, applying uniform circumferential pressure to the edge of the skin through the arc contour, causing the skin to close synchronously along the circumferential direction.

[0056] Specifically, the production line also includes an output conveyor belt, on which a turning mechanism 91 is installed. The turning mechanism 91 is used to flip the workpiece. When the vertical lifting support unit descends to a preset position, the transfer conveyor belt connects with the output conveyor belt, and the transfer conveyor belt can output the processed finished product to the output conveyor belt 9.

[0057] The discharge conveyor belt 9 is provided with two conveyor sections with different travel heights, and the turning mechanism 91 is located at the height difference between the two conveyor sections. The finished product is transported to the turning mechanism 91 via the first conveyor section, and is turned over and falls into the second conveyor section by the turning mechanism 91 to meet the discharge of the finished product.

[0058] Furthermore, the flipping mechanism 91 includes a flipping motor 912 and a flipping action plate 911. The flipping motor 912 drives and connects to the flipping action plate 911. When the finished product is conveyed to the flipping action plate 911 through the first conveying section, the flipping motor 912 can drive the flipping action plate 911 to flip over, thereby realizing the flipping operation of the finished product.

[0059] The application achieves automated posture adjustment during the unloading stage of filled workpieces. By replacing manual intervention with mechanical flipping, it eliminates the hygiene risks caused by human contact with food. Synchronized control of the flipping mechanism and the conveyor belt speed allows the workpieces to complete the flipping action without interruption, maintaining the continuous operation of the production line. After flipping, the bottom folded surface of the workpiece faces upwards, facilitating secondary pressing of the sealing area by subsequent processing equipment. Simultaneously, the directional arrangement of the sealing seams provides a standardized interface for the gripping and positioning of subsequent packaging machinery, effectively solving the problem of low processing efficiency caused by chaotic workpiece posture in traditional production lines.

[0060] The puff pastry imitation hand-wrapped filling production line provided in this embodiment of the invention outputs the dough blanks through a conveyor line, which then pass through the pressing component 4 and the loading component in sequence. The filling component 6, which is equipped with a lifting receiving unit and a horizontal filling unit, performs the imitation hand-wrapping operation, thereby improving the filling efficiency and filling quality of the finished product and realizing efficient and high-quality fully automatic filling production.

[0061] Furthermore, the above provides a detailed description of a puff pastry imitation handmade filling production line provided by the embodiments of the present invention. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present invention.
