Description

Technical Field

[0001] This invention relates to a multi-layer blank layered filler folding device. Background Technology

[0002] Thousand-layer meat pie is a type of pasta snack, loved by consumers for its golden color, distinct layers, crispy exterior and tender interior, fragrant and delicious taste, and non-greasy texture. The traditional method of making thousand-layer pie involves five steps: rolling out the dough, spreading the filling, cutting lines, folding, and flattening. First, the risen dough is rolled into a square sheet about 3mm thick. Then, the prepared meat filling is evenly spread on the sheet. Next, about half or one-third of the square sheet is cut with a blade to begin folding. The layers are then folded one by one in a clockwise or counterclockwise direction. Finally, the folded pie is evenly flattened, completing the initial preparation of the thousand-layer pie dough. However, currently, the initial preparation of thousand-layer pie is all done manually, which is very labor-intensive. There is currently no food processing equipment that can replace manual labor in the initial preparation of thousand-layer pie, resulting in low production efficiency and hindering large-scale production and convenient processing.

[0020] The electrical control device moves the dough folding platform under the drive of the lead screw motor and lead screw to the area below the dough blank outlet of the dough press, allowing the falling dough blank to land at the right end of the dough folding platform. Then, the electrical control device stops the movement of the dough folding platform and starts the dough press to process the dough blank. The dough blank is then output downwards through the dough blank outlet. When the bottom end of the downward-moving dough blank contacts and overlaps the right end of the dough folding platform, the electrical control device moves the dough folding platform from left to right at the same speed as the falling dough blank, driven by the lead screw motor and lead screw, until the top end of the falling dough blank overlaps the left end of the dough folding platform. The front-to-back dimension of the dough blank is equal to the front-to-back dimension of the dough folding platform.

[0021] Then, via an electrical control device, the dough folding platform, driven by a lead screw motor and lead screw, moves to below the filling outlet of the layered pastry filling device, allowing the falling filling to land on the dough blank located at the right end of the dough folding platform. The electrical control device then activates the filling roller drive motor, which drives the active filling roller to rotate. The rotating active filling roller drives the driven filling roller to rotate as well. The driven filling roller, in turn, drives the vertical shaft to rotate via a pair of front lower drive bevel gears. The vertical shaft, in turn, drives the drive shaft to rotate via a pair of front upper drive bevel gears. The drive shaft, through each pair of helical drive bevel gears, drives the corresponding helical shafts and helical blades to rotate. After filling is added to the hopper, gravity and the rotating helical blades push the filling downwards to the active and driven filling rollers. The filling is then placed into the active filling rollers by multiple active filling grooves on the active filling rollers and the driven filling rollers by multiple driven filling grooves on the driven filling rollers. The filling groove roll passes through the filling outlet, allowing the filling to fall downwards onto the dough blank located at the right end of the dough folding platform. The linear velocity of the circumferential surface of the active filling roller is equal to the speed at which the dough folding machine base moves to the left under the drive of the lead screw motor and lead screw. The upper surfaces of the left front small pressure plate, left front large pressure plate, left rear small pressure plate, left rear large pressure plate, right rear small pressure plate, right rear large pressure plate, and fixed panel are aligned with the bottom end of the circumferential surface of the active filling roller and the active filling roller. 7. The distance between the bottom ends of the circumferential surfaces is slightly greater than the thickness of the dough. The filling is spread and pressed down by the active filling roller and then adheres to the upper surface of the soft dough. When the filling falls onto the upper surface of the dough at the right end of the dough folding platform, the electric control device makes the dough folding platform move from left to right under the drive of the lead screw motor and lead screw until the falling filling covers the upper surface of the dough. Then the electric control device makes the filling roller drive motor stop rotating.

[0022] Then, the electrical control device moves the dough folding platform to the left side of the slide under the drive of the lead screw motor and lead screw. The electrical control device also drives the incomplete gear shaft drive motor to rotate the incomplete gear clockwise. The teeth of the incomplete gear first mesh with the front rack, driving the front rack to move to the left along the front rack guide groove. At the same time, the front rack will stretch the front rack return spring. The leftward movement of the front rack will cause the lower left end of the front swing arm to move to the left and the upper right end of the front swing arm to swing downward clockwise. At the position where the incomplete gear and the front rack are about to disengage, the cutting edge of the dough cutting knife cuts the dough blank along the gap between the left front small pressure plate, the left front large pressure plate and the fixed panel. Then the incomplete gear continues to rotate and disengages from the front rack. The front rack, the front swing arm and the dough cutting knife return to their original positions under the tension of the front rack return spring.

[0023] Then the incomplete gear continues to rotate clockwise, allowing its teeth to mesh with the left rack and drive it to move backward along the left rack guide groove. At the same time, the left rack stretches the left rack return spring, enabling it to push the front end of the left front pressure plate to flip backward above the rear end of the left rear pressure plate via the left rocker arm, and keeping the left front small pressure plate upright. This causes the front left part of the dough to be flipped and pressed against the top of the rear left part of the dough by the left front large pressure plate. At the point where the incomplete gear and the left rack are about to disengage, the front left and rear left parts of the dough are pressed down by the left front large pressure plate. Then the incomplete gear continues to rotate and disengages from the left rack. The left front small pressure plate, the left front large pressure plate, the left rack, and the left rocker arm return to their original positions under the tension of the left rack return spring.

[0024] Then the incomplete gear continues to rotate clockwise, allowing its teeth to mesh with the rear rack and drive it to move to the right along the rear rack guide groove. At the same time, the rear rack stretches the rear rack return spring, enabling it to push the left end of the left rear large pressure plate to flip to the right above the right end of the right rear large pressure plate via the rear swing arm, and keeping the left rear small pressure plate upright. This causes the left front and left rear parts of the dough to be flipped and pressed against the top of the right rear part of the dough by the left rear large pressure plate. At the point where the incomplete gear and the rear rack are about to disengage, the left front, left rear, and right rear parts of the dough are pressed down by the left rear large pressure plate. Then the incomplete gear continues to rotate and disengages from the rear rack. The left rear small pressure plate, the left rear large pressure plate, the rear rack, and the rear swing arm return to their original positions under the tension of the rear rack return spring.

[0025] Then, the incomplete gear continues to rotate clockwise, allowing its teeth to mesh with the right rack and drive it forward along the right rack guide groove. Simultaneously, the right rack stretches the right rack return spring, enabling it to push the rear end of the right rear large pressure plate forward to the front end of the fixed panel via the right rocker arm, and keeping the right rear small pressure plate upright. This causes the left front, left rear, and right rear parts of the dough to be flipped and pressed against the top of the right front part of the dough by the right rear large pressure plate. At the point where the incomplete gear and the right rack are about to disengage, the left front, left rear, right rear, and right front parts of the dough are pressed down by the right rear large pressure plate. Then, the incomplete gear continues to rotate and disengages from the right rack. The right rear small pressure plate, left rear large pressure plate, right rack, and right rocker arm return to their original positions under the tension of the right rack return spring.

[0026] Preferably, the first active roller shaft, multiple follower roller shafts, and the second active roller shaft can be adjusted and fixed in position along the radial direction of the large roller shaft to change the width of the dough pressing channel. The number of follower roller shafts is 2-6. 2-3 spiral shafts are evenly arranged in the vertical direction inside the bracket. The cross-section of the feed inlet and the filling outlet is rectangular.

[0027] Preferably, the front end of the active filling roller is connected to the front end of the driven filling roller via a cylindrical gear transmission, and the motor shaft of the filling roller drive motor is connected to the front end of the active filling roller via a bevel gearbox.

[0028] Preferably, the filling roller drive motor, the incomplete gear shaft drive motor, and the lead screw motor are speed-regulating motors.

[0029] The multi-layer dough layering and filling folding device of the present invention has a slide rail on its frame along the left and right direction. A sliding block is provided on the slide rail, and the sliding block can reciprocate along the slide rail under the drive of a lead screw motor and a lead screw. A dough folding device is located on the top of the sliding block. A dough press and a layered cake filling device are arranged sequentially from right to left on the right side of the slide rail. In use, the dough press can process soft dough into dough blanks, the layered cake filling device can spread and press the filling onto the upper surface of the dough blank, and the dough blank folding device can fold the filled dough blank into the required shape for layered cakes. Therefore, the multi-layer dough layering and filling folding device of the present invention has the characteristics of efficiently and quickly completing the rolling, filling, folding, and flattening processes, significantly improving the production efficiency of the early stage of layered cake production, and significantly reducing the labor intensity of workers.

[0065] The electrical control device moves the dough folding platform under the drive of the lead screw motor 29 and lead screw 21 to below the dough blank outlet of the dough press, allowing the falling dough blank to land at the right end of the dough folding platform. Then, the electrical control device stops the movement of the dough folding platform and starts the dough press to process the dough blank. The dough blank is then output downward through the dough blank outlet. When the bottom end of the downward-moving dough blank contacts and overlaps the right end of the dough folding platform, the electrical control device moves the dough folding platform from left to right at the same speed as the falling dough blank, driven by the lead screw motor 29 and lead screw 21, until the top end of the falling dough blank overlaps the left end of the dough folding platform. The front-back dimension of the dough blank is equal to the front-back dimension of the dough folding platform.

[0066] Then, the electrical control device moves the dough folding platform under the drive of the lead screw motor 29 and lead screw 21 to below the filling outlet 8 of the layered pastry filling device, allowing the falling filling to land on the dough blank located at the right end of the dough folding platform. Then, the electrical control device activates the filling roller drive motor 11, which drives the active filling roller 6 to rotate. The rotating active filling roller 6 drives the driven filling roller 7 to rotate together. The driven filling roller 7 is driven by a pair of front-downward drive bevel gears. 19 drives the vertical shaft 17 to rotate, and the vertical shaft 17 drives the drive shaft 20 to rotate via a pair of front upper drive bevel gears 16. The drive shaft 20 drives the corresponding spiral shafts 13 and spiral blades 14 to rotate via each pair of spiral drive bevel gears 15. After filling is added into the hopper 1, gravity and the rotating spiral blades 14 will push the filling into the hopper 1 downward to the active filling roller 6 and the driven filling roller 7. Then the filling will be coated by multiple active filling grooves 9 on the active filling roller 6 and multiple driven filling grooves 7 on the driven filling roller 7. The filling groove 10 rolls through the filling outlet 8, allowing the filling to fall downwards onto the dough blank located at the right end of the dough folding platform. The linear velocity of the circumferential surface of the active filling roller 6 is equal to the speed at which the dough folding machine base 28 moves to the left under the drive of the lead screw motor 29 and lead screw 21. The upper surfaces of the left front small pressure plate 33, left front large pressure plate 331, left rear small pressure plate 32, left rear large pressure plate 321, right rear small pressure plate 31, right rear large pressure plate 311, and the fixed panel 30 are in contact with the circumferential surface of the active filling roller 6. The distance between the bottom of the active filling roller 7 and the bottom of the circumferential surface of the active filling roller 6 is slightly greater than the thickness of the dough. The filling is spread, pressed down and embedded and adhered to the upper surface of the soft dough after being spread by the active filling roller 6. When the filling falls onto the upper surface of the dough at the right end of the dough folding platform, the electric control device makes the dough folding platform move from left to right under the drive of the lead screw motor 29 and lead screw 21 until the falling filling covers the upper surface of the dough. Then the electric control device makes the filling roller drive motor 11 stop rotating.

[0067] Then, via an electrical control device, the sheet folding platform moves to the left side of the slide 22 under the drive of lead screw motors 29 and 21, and the incomplete gear shaft drive motor 27 drives the incomplete gear 26 to rotate clockwise via the electrical control device. See [link to relevant documentation]. Figure 10 , Figure 11The teeth of the incomplete gear 26 first mesh with the front rack 34, driving the front rack 34 to move to the left along the front rack guide groove. At the same time, the front rack 34 stretches the front rack return spring 35. The leftward movement of the front rack 34 causes the lower left end of the front swing arm 37 to move to the left and the upper right end of the front swing arm 37 to swing downward in a clockwise direction. At the position where the incomplete gear 26 and the front rack 34 are about to disengage, the cutting edge of the dough cutting knife 41 cuts the dough blank along the gap between the left front small pressure plate 33, the left front large pressure plate 331 and the fixed panel 30. At this time, the state of the mille-feuille dough blank being cut is as follows. Figure 12 As shown, the incomplete gear 26 then continues to rotate and disengages from the front rack 34. The front rack 34, the front rocker arm 37, and the blank cutter 41 return to their original positions under the tension of the front rack return spring 35.

[0068] Then the incomplete gear 26 continues to rotate clockwise, see... Figure 11 , Figure 13 The incomplete gear 26 meshes with the left rack 44, driving the left rack 44 to move backward along the left rack guide groove. Simultaneously, the left rack 44 stretches the left rack return spring 45, allowing it to push the front end of the left front pressure plate 331 backward via the left swing arm 47, placing it above the rear end of the left rear pressure plate 321. This keeps the left front pressure plate 33 upright, causing the left front part of the dough to be flipped and pressed against the top of the left rear part of the dough by the left front pressure plate 331. At the point where the incomplete gear 26 and the left rack 44 are about to disengage, the left front and left rear parts of the dough are pressed downward by the left front pressure plate 331. At this point, the folded layered dough is in the following state: Figure 14 As shown; then the incomplete gear 26 continues to rotate and disengages from the left rack 44, and the left front small pressure plate 33, the left front large pressure plate 331, the left rack 44 and the left swing rod 47 return to their original positions under the pulling force of the left rack return spring 45;

[0069] Then the incomplete gear 26 continues to rotate clockwise, see... Figure 15 The incomplete gear 26 meshes with the rear rack 54, driving the rear rack 54 to move to the right along the rear rack guide groove. Simultaneously, the rear rack 54 stretches the rear rack return spring 55, allowing it to push the left end of the left rear large pressure plate 321 to the right above the right end of the right rear large pressure plate 311 via the rear swing rod 57. This puts the left rear small pressure plate 32 in an upright position, causing the left front and left rear parts of the dough to be flipped and pressed against the top of the right rear part of the dough by the left rear large pressure plate 321. At the point where the incomplete gear 26 and the rear rack 54 are about to disengage, the left front, left rear, and right rear parts of the dough are pressed downwards by the left rear large pressure plate 321. At this point, the folded layered dough is in the following state: Figure 16As shown; then the incomplete gear 26 continues to rotate and disengages from the rear rack 54, and the left rear small pressure plate 32, the left rear large pressure plate 321, the rear rack 54 and the rear swing rod 57 return to their original positions under the pulling force of the rear rack return spring 55;

[0070] Then the incomplete gear 26 continues to rotate clockwise, see... Figure 17 The incomplete gear 26 meshes with the right rack 64, driving the right rack 64 forward along the right rack guide groove. Simultaneously, the right rack 64 stretches the right rack return spring 65, allowing it to push the rear end of the right rear large pressure plate 311 forward to above the front end of the fixed panel 30 via the right swing arm 67. This also puts the right rear small pressure plate 31 in an upright position. Consequently, the left front, left rear, and right rear parts of the dough are flipped and pressed against the top of the right front part of the dough by the right rear large pressure plate 311. At the point where the incomplete gear 26 and the right rack 64 are about to disengage, the left front, left rear, right rear, and right front parts of the dough are pressed downwards by the right rear large pressure plate 311. At this point, the folded layered dough is in the following state: Figure 18 As shown, this completes the initial processing of making the layered pancake dough, applying the filling to the layered pancake dough, and folding the filled dough into shape; then the incomplete gear 26 continues to rotate and disengages from the right rack 64, and the right rear small pressure plate 31, the left rear large pressure plate 321, the right rack 64, and the right swing rod 67 return to their original positions under the tension of the right rack return spring 65.
