Description

Technical Field

[0001] This invention relates to the field of egg tart crust production equipment technology, and more particularly to a mechanical linkage production equipment for egg tart crusts. Background Technology

[0002] Egg tarts, a common baked delicacy, typically consist of two parts: the tart shell and the egg custard. The tart shell is a step before baking, requiring it to be attached to a foil cup. This manual process is tedious, and currently, there are no mechanized tart shell forming machines. Existing tart shell forming machines rely mainly on the coordination of electrical control and pneumatic circuits to achieve the required operation, which makes it difficult to improve efficiency, and the complex circuitry is not conducive to later maintenance. Therefore, there is a need to develop a more convenient mechanical linkage tart shell forming device. Summary of the Invention

[0055] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0056] This embodiment describes a mechanical linkage production equipment for egg tart crusts, such as... Figure 1-12 As shown, it includes:

[0057] Machine base 1, the top surface of the machine base 1 is formed with a table 11, and a support 12 is provided on the table 11;

[0058] A pressing and forming mechanism 2 is installed on the support 12 and is used to press the dough into shape.

[0059] The turntable mechanism 3 is provided with a plurality of pressing molds 31. The turntable mechanism 3 rotates to move each pressing mold 31 in turn to the underside of the pressing and forming mechanism 2.

[0060] The feeding mechanism 4 is used to push the egg tart crust that has been pressed and formed in the turntable mechanism 3 out of the pressing mold 31.

[0061] Drive unit 5, which is connected to the pressing and forming mechanism 2 to drive the pressing and forming mechanism 2;

[0062] A first transmission mechanism 6 is connected between the drive unit 5 and the turntable mechanism 3 so that the drive unit 5 drives the turntable mechanism 3.

[0063] The second transmission mechanism 7 is connected between the first transmission mechanism 6 and the unloading mechanism 4 to drive the unloading mechanism 4.

[0064] By setting up the first transmission mechanism 6 and the second transmission mechanism 7, only one drive unit 5 is needed to simultaneously drive the pressing and forming mechanism 2, the turntable mechanism 3, and the unloading mechanism 4. Therefore, the production rhythm of the equipment can be adjusted simply by controlling the speed of the drive unit 5, making equipment debugging and electrical control simpler. Moreover, the single drive source can effectively reduce production costs. Furthermore, due to the reduction of electrical components, the circuit of the whole machine is very simple, making it easy to maintain. By setting up the first transmission mechanism 6 and the second transmission mechanism 7, the pressing and forming mechanism 2, the turntable mechanism 3, and the unloading mechanism 4 can achieve mechanical linkage, thereby replacing the traditional electric and pneumatic control. This can better improve the stability and reliability of the equipment, extend its service life, and reduce maintenance costs.

[0065] The turntable mechanism 3 has a feeding side and a discharging side. In actual production, the carrier and dough are first placed into each pressing mold 31 from the feeding side. The carrier can be an aluminum foil cup. As the turntable mechanism 3 rotates, the carrier and dough located on the feeding side are moved to the pressing and forming mechanism 2 in sequence. The pressing and forming mechanism 2 presses the dough in the pressing mold 31 into shape, thereby obtaining the egg tart crust. As the turntable mechanism 3 rotates, the pressed egg tart crust moves to the discharging side. The unloading mechanism 4 pushes the egg tart crust out of the pressing mold 31, making the pressing mold 31 empty. As the turntable mechanism 3 rotates, it returns to the feeding side to place the carrier and dough. This cycle repeats, so that egg tart crusts can be pressed continuously.

[0066] Specifically, such as Figure 1-5 As shown, the pressing and molding mechanism 2 includes a first slide plate 21, a first slide rail 22, a first cam 23, a second cam 24, a connecting seat assembly 25, a first bearing seat 26, a first rotating shaft 27, and a die head 28. The first slide rail 22 is vertically mounted on the bracket 12. The first slide plate 21 is slidably connected to the first slide rail 22. There are two first bearing seats 26, which are respectively disposed on both sides of the slide plate. The two ends of the first rotating shaft 27 are rotatably connected to the first bearing seats 26. The first cam 23 and the second cam 24 are fixedly mounted on the first rotating shaft 27. The upper end of the first slide plate 21 is provided with a first rotating wheel 211 that cooperates with the first cam 23, and the lower end of the first slide plate 21 is provided with a second rotating wheel 212 that cooperates with the second cam 24. The connecting seat assembly 25 is disposed at the bottom of the first slide plate 21, and the die head 28 is mounted on the connecting seat assembly 25.

[0067] The drive unit 5 includes a motor 51 and a hollow shaft reducer 52. The hollow shaft reducer 52 is mounted on the bracket 12. The motor 51 is connected to the input shaft of the hollow shaft reducer 52. The first rotating shaft 27 passes through the hollow shaft reducer 52.

[0068] The first slide plate 21 slides vertically with the first slide rail 22. The first cam 23 and the second cam 24 form a conjugate cam. When the drive unit 5 drives the first cam 23 and the second cam 24 to rotate, the first cam 23 engages with the first rotating wheel 211, and the second cam 24 engages with the second rotating wheel 212, thereby driving the first slide plate 21 to rise or fall. Specifically, during the rising process, the first cam 23 applies force to the first rotating wheel 211, causing the first rotating wheel 211 to drive the first slide plate 21 to rise. At this time, the second rotating wheel 212 remains in close contact with the second cam 24. During the falling process, the first rotating wheel 211 remains in close contact with the first cam 23, under the influence of gravity and... Under the pressure of the second cam 24 on the second rotating wheel 212, the first slide plate 21 slides down along the first slide rail 22, so that the mold head 28 presses the dough in the pressing mold 31 into shape, and then starts to rise again. By setting the first cam 23 and the second cam 24, the first slide plate 21 can better follow the first cam 23 and the second cam 24 to slide up and down. The setting of the second cam 24 can provide sufficient pressing force during the pressing process. Compared with the structure of pulling down with a spring, the pressure on the dough can remain unchanged during long-term use, thereby ensuring more stable product quality.

[0069] Furthermore, such as Figure 3 As shown, the connecting seat assembly 25 includes a pressing connecting rod 251, a die head connecting plate 252, a die head connecting rod 253, and a die head mounting plate 254. The upper end of the pressing connecting rod 251 is fixedly connected to the first sliding plate 21, and the die head connecting plate 252 is fixed to the bottom of the pressing connecting rod 251. There are two sets of die head connecting rods 253, each set consisting of two rods. The two sets of die head connecting rods 253 are respectively disposed at both ends of the die head connecting plate 252, and the upper end of the die head connecting rod 253 is fixedly connected to the die head connecting plate 252. The lower end of each set of die head connecting rods 253 is fixedly connected to the same die head mounting plate 254.

[0070] The mold head 28 includes a mold head body 281 and a protruding ring 282. The protruding ring 282 is disposed in the middle of the mold head body 281. The top surface of the protruding ring 282 is fixedly connected to the mold head mounting plate 254 by screws.

[0071] By pressing the connecting rod 251 and the die head connecting plate 252, the installation position of the die head 28 can be lowered, allowing the die head 28 to be pressed into the pressing mold 31. This arrangement also reduces the weight of the first slide plate 21, making it easier and more flexible to lift and lower the first slide plate 21 when driven by the first cam 23 and the second cam 24, while also reducing energy consumption. The lower end of the die head connecting rod 253 is fixedly connected to the protruding ring 282 of the die head 28 via the die head mounting plate 254, thereby connecting the die head 28 to the connecting seat assembly 25. The top surface of the mold head 28 is pressed against the bottom surface of the mold head connecting plate 252. During the process of the mold head 28 pressing the dough into egg tart crusts, the mold head connecting plate 252 can provide downward pressure on the mold head 28, while the mold head connecting rod 253 only serves to fix the mold head 28 to the mold head connecting plate 252, and can move the fixed position down to the mold head mounting plate 254. Since there is a large space between the mold head mounting plate 254 and the mold head connecting plate 252, the mold head 28 can be easily repaired and replaced.

[0072] Furthermore, such as Figure 4 As shown, the first cam 23 is provided with a first alignment hole 231, and the second cam 24 is provided with a second alignment hole 241 that has the same shape as the first alignment hole 231. The first alignment hole 231 and the second alignment hole 241 are aligned.

[0073] With this configuration, the first cam 23 and the second cam 24 can be positioned using the first alignment hole 231 and the second alignment hole 241 during installation. This ensures that the first cam 23 and the second cam 24 can be installed correctly, avoiding problems such as jamming or stuck during operation. It should be noted that the first alignment hole 231 and the second alignment hole 241 are irregularly shaped so that they can be aligned in only one specific position.

[0074] The second cam 24 is provided with first through holes 242 symmetrically on both sides of the second alignment hole 241.

[0075] By setting the first through hole 242, the weight of the second cam 24 can be reduced, which not only makes the second cam 24 more stable when rotating and reduces the shaking caused by uneven weight, but also reduces power consumption to a certain extent.

[0076] Furthermore, such as Figure 1 and Figure 12 As shown, the machine base 1 is fixedly provided with a lower mounting plate 13 below the table surface 11; as Figure 5 and 6As shown, the turntable mechanism 3 includes a mold turntable 32, a turntable bearing 33, a second rotating shaft 34, a shifting turntable 35, and a shift fork limiting assembly 36. The turntable bearing 33 is mounted on the top surface of the machine base 1, and the mold turntable 32 is mounted on the top surface of the turntable bearing 33. The pressing molds 31 are arranged equidistantly around the axis of the mold turntable 32. The upper end of the second rotating shaft 34 passes through the machine base 1 and the turntable bearing 33 and is fixedly connected to the mold turntable 32. The lower end of the second rotating shaft 34 passes through the lower mounting plate 13 and is fixedly connected to the shifting turntable 35; the top surface of the shifting turntable 35 is provided with a plurality of shifting posts 351, which are equidistantly arranged around the axis of the shifting turntable 35; the bottom surface of the shifting turntable 35 is provided with a plurality of limiting posts 352, which are equidistantly arranged around the axis of the shifting turntable 35; the shift fork limiting assembly 36 is installed on the bottom surface of the lower mounting plate 13;

[0077] Furthermore, such as Figure 5 and 12 As shown, the lower mounting plate 13 is provided with a second through hole 14, and a first bearing 15 is installed in the second through hole 14. The first bearing 15 is rotatably engaged with the second rotating shaft 34.

[0078] The cooperation between the second rotating shaft 34 and the first bearing 15 can limit the lower end of the second rotating shaft 34, making the second rotating shaft 34 more stable when rotating.

[0079] The first transmission mechanism 6 includes a first transmission shaft 61 and a reversing gearbox 62. The first transmission shaft 61 is rotatably mounted on the bracket 12. The upper end of the first transmission shaft 61 is connected to the first rotating shaft 27 via a bevel gear. The lower end of the first transmission shaft 61 passes through the platform 11 and is connected to the input shaft of the reversing gearbox 62 via a bevel gear. The output shaft of the reversing gearbox 62 is connected to the shift fork limiting assembly 36 to drive the shift fork limiting assembly 36 to release the limiting post 352 when the shift post 351 is moved to make the shift turntable 35 rotate, and to limit the limiting post 352 when the shift post 351 is moved to the correct position.

[0080] The mold turntable 32 is used to support the pressing mold 31. The mold turntable 32 is connected to the shifting turntable 35 through the second rotating shaft 34. Therefore, when the shifting turntable 35 rotates, the mold turntable 32 can be driven to rotate synchronously through the second rotating shaft 34. The drive unit 5 transmits power to the turntable mechanism 3 through the first transmission mechanism 6. The first transmission mechanism 6 drives the third cam 37 to rotate. The third cam 37 drives the shifting fork limiting assembly 36 to sequentially shift the shifting column 351, so that the shifting turntable 35 can rotate a certain angle each time. This drives the mold turntable 32 to move the pressing mold 31, which is loaded with the carrier and dough, to the pressing and forming mechanism 2 for pressing. After pressing, the mold turntable 32 moves the pressing mold 31 out of the pressing and forming mechanism 2 and moves the next pressing carrier to the pressing and forming mechanism 2. The pressing process continues, allowing for the continuous pressing of tart shells. However, when the shifting fork limit assembly 36 moves to the next shifting post 352, it needs to disengage from the previous shifting post 351. During this process, the shifting turntable 35 is prone to displacement due to vibration and inertia, causing the pressing mold 31 and the die head 28 to misalign, affecting product quality. Therefore, by setting a limit post 352 on the bottom surface of the shifting turntable 35, the shifting fork limit assembly 36 limits the limit post 352 when it leaves the shifting post 351, ensuring the shifting turntable 35 remains stationary and allowing the pressing mold 31 and the die head 28 to align perfectly, thereby improving product quality and yield.

[0081] Furthermore, such as Figure 5 and 6As shown, the shift fork limiting assembly 36 includes a mounting bracket 361, a first slide block 362, a lower slide block 363, a second slide block 364, a third cam 37, a cam frame 365, a limiting arm 366, and a shift fork 367. The mounting bracket 361 is fixed to the bottom surface of the lower mounting plate 13. The first slide block 362 is mounted on the inner bottom surface of the mounting bracket 361. The lower slide block 363 is slidably connected to the first slide block 362 to move closer to and further away from the shifting turntable 35. The second slide block 364 is disposed on the top surface of the lower slide block 363, and the second slide block 364 is perpendicular to the first slide block 362. The cam frame 365 is slidably connected to the second slide block 364. The cam frame 365 is hollow inside, and the third cam 37 engages with the inner wall of the cam frame 365. The reversing gear... The output shaft of the wheel box 62 is connected to the third cam 37; the shift fork 367 is installed on one end of the cam frame 365 near the shifting turntable 35, and the shift fork 367 is used to sequentially move the shifting column 351 to make the shifting turntable 35 rotate; the limiting arm 366 is installed on one end of the lower slide plate 363 near the shifting turntable 35, the limiting wall is provided with a limiting slide rail 3661, and a relief groove 3662 is provided between the limiting slide rail 3661 and the lower slide plate 363, the limiting arm 366 is used to make the limiting column 352 slide from the relief groove 3662 into the limiting slide rail 3661 for limiting when the shift fork 367 leaves the shifting column 351, and to make the limiting column 352 leave the limiting slide rail 3661 when the shift fork 367 moves the shifting column 351.

[0082] When the third cam 37 rotates under the drive of the first transmission mechanism 6, the third cam 37 drives the cam frame 365 to slide along the second slide block 364. Since the second slide block 364 is mounted on the lower slide plate 363, the second slide block 364 can move in a direction perpendicular to its extension. Therefore, the cam frame 365 can move cyclically in a plane according to a certain arc-shaped closed loop trajectory under the drive of the third cam 37, so as to sequentially move each shifting column 351, causing the shifting turntable 35 to rotate intermittently. Driven by the third cam 37, the lower slide plate 363 reciprocates along the first slide block 362. In the extending direction of the first slide block 362, the movement of the lower slide plate 363 and the cam frame 365 is synchronized. The lower slide plate 363, by driving the limiting arm 366 to reciprocate, can limit the limiting post 352 when the shift fork 367 leaves the shift post 351. Specifically, when the shift fork 367 leaves the shift post 351, the shift post 351 and the shift fork 367 are switched on the next shift. The limiting post 352 between the posts 351 enters the limiting arm 366 from the relief groove 3662 and slides into the limiting slide rail 3661. As the shift fork 367 and the limiting arm 366 retract, the two sides of the limiting slide rail 3661 maintain the restriction on the limiting post 352. When the shift fork 367 extends forward and approaches the next shift post 351, the limiting arm 366 also extends forward at the same time, causing the limiting post 352 to move closer to the relief groove 3662. When the shift fork 367 holds the shift post 351, the limiting post... 352 also moves into the relief groove 3662. As the shift fork 367 moves the shifting post 351, the limiting post 352 also moves away from the limiting arm 366 from the relief groove 3662 along with the movement of the shifting turntable 35. This cycle repeats, so that the shifting turntable 35 can rotate intermittently. And when the shift fork 367 leaves the shifting post 351, it can still position the shifting turntable 35 so that the pressing mold 31 can be aligned with the die head 28 during the pressing process, thereby improving the quality of the product.

[0083] Furthermore, the number of pressing molds 31, the number of shifting posts 351, and the number of limiting posts 352 are equal. The shifting posts 351 and the limiting posts 352 are staggered, and the shifting posts 351 are located on the angle bisector of the central angle formed by two adjacent limiting posts 352.

[0084] Since the limiting arm 366 can only move along the extension direction of the first slide block 362, while the shift fork 367 can not only extend and retract synchronously with the limiting arm 366, but also move to both sides of the limiting arm 366, thereby actuating the shifting column 351. It should be noted that the extreme positions of the shift fork 367 to both sides of the limiting arm 366 are symmetrical about the limiting arm 366. With this setting, when the shift fork 367 moves the shifting column 351 from one side of the limiting arm 366 to the other side, the limiting column 352 between the shifting column 351 and the next shifting column 351 can just move to the moving path of the limiting arm 366. Thus, the limiting arm 366 only needs to extend and retract to restrict the limiting column 352 within the limiting slide 3661, making the structure of the shift fork limiting assembly 36 simpler and more compact.

[0085] Furthermore, such as Figure 7 As shown, the feeding mechanism 4 includes an ejection assembly 41, which includes a fourth cam 411, an ejection slide plate 412, an ejection mounting plate 413, a second slide rail 414, an ejector rod 415, and a first reset assembly 416. The fourth cam 411 is connected to the second transmission mechanism 7. The ejection mounting plate 413 is fixed to the top surface of the lower mounting plate 13. The second slide rail 414 is vertically mounted on the ejection mounting plate 413. The ejection slide plate 412 slides along the second slide rail 414. The top of the ejector plate 412 extends toward the fourth cam 411, and the top of the ejector plate 412 engages with the fourth cam 411; the push rod 415 has an L-shaped structure, one end of the push rod 415 is connected to the ejector plate 412, and the other end extends upward; one end of the first reset assembly 416 is connected to the ejector plate 412, and the other end is connected to the lower mounting plate 13, and the first reset assembly 416 is used to apply a downward elastic force to the ejector plate 412;

[0086] The second transmission mechanism 7 includes a second bearing seat 71 and a second transmission shaft 72. There are two second bearing seats 71. The second bearing is disposed on the lower mounting plate 13. The second transmission shaft 72 is disposed between the two second bearing seats 71. The second transmission shaft 72 is connected to the input shaft of the reversing gearbox 62 via a synchronous belt drive. The fourth cam 411 is mounted on the second transmission shaft 72.

[0087] The second transmission mechanism 7 drives the fourth cam 411 to rotate. During the rotation, the fourth cam 411 intermittently pushes the ejector plate 412 upward. The ejector plate 412 slides upward under the push of the fourth cam 411, and the ejector plate 412 drives the ejector rod 415 to move upward, thereby ejecting the pressed egg tart shells in the pressing mold 31. As the fourth cam 411 continues to rotate, the ejector plate 412 moves downward under the elastic action of the first reset component 416, so that the ejector plate 412 can quickly reset. After the next pressing mold 31 containing egg tart shells moves to the top of the ejector rod 415, the fourth cam 411 has just rotated one revolution and pushes the ejector plate 412 again, and so on.

[0088] Furthermore, the feeding mechanism 4 also includes an ejection assembly 42, which includes a fifth cam 421, an ejection mounting plate 422, a third slide rail 423, an ejection slide plate 424, a push rod 425, and a second reset assembly 426. The ejection mounting plate 422 is mounted on the bracket 12, the third slide rail 423 is horizontally mounted on the ejection mounting plate 422, the ejection slide plate 424 is slidably connected to the third slide rail 423, the fifth cam 421 cooperates with the ejection slide plate 424, one end of the push rod 425 is fixedly connected to the ejection slide plate 424, and the other end of the push rod 425 extends toward the mold turntable 32 for ejecting the tart shells ejected by the ejection assembly 41 from the pressing mold 31. One end of the second reset assembly 426 is connected to the ejection slide plate 424, and the other end is connected to the machine base 1. The second reset assembly 426 is used to apply an elastic force toward the fifth cam 421 to the ejection slide plate 424.

[0089] The second transmission mechanism 7 further includes a third bearing seat 73 and a third transmission shaft 74. There are two third bearing seats 73, which are disposed on the platform 11. The third transmission shaft 74 passes through the two third bearing seats 73. One end of the third transmission shaft 74 is connected to the first transmission shaft 61 through a bevel gear. The fifth cam 421 is installed on the other end of the third transmission shaft 74.

[0090] The second transmission mechanism 7 drives the fifth cam 421 to rotate. The fifth cam 421 intermittently pushes the ejector plate 424, causing the ejector plate 424 to move horizontally along the third slide rail 423 and the push rod 425. This allows the egg tart shells ejected from the pressing mold 31 by the ejector assembly 41 to be pushed out of the pressing mold 31, so that the pressing mold 31 returns to an empty state to wait for the next pressing. The second reset assembly 426 always applies a spring force to the ejector plate 424, so that the ejector plate 424 can quickly retract and reset after the egg tart shells are ejected. After the next pressing mold 31 containing egg tart shells moves to the bottom of the push rod 425, the fifth cam 421 has just completed one revolution and pushes the ejector plate 424 again, and so on.

[0091] Furthermore, the first reset assembly 416 includes a first mounting plate 417 and a first spring 418. The first mounting plate 417 is fixed to the lower mounting plate 13, and one end of the first spring 418 is connected to the first mounting plate 417 and the other end is connected to the ejection slide plate 412.

[0092] When the ejector slide 412 is pushed upward by the fourth cam 411, the first hanging plate 417 moves upward along with the ejector slide 412, thereby stretching the first spring 418. As the fourth cam 411 continues to rotate until it leaves the ejector slide 412, the first spring 418 will immediately retract, thereby pulling the ejector slide 412 downward and quickly resetting it.

[0093] Similarly, the second reset assembly 426 includes a second mounting plate 427, a second spring 428, and a third mounting plate 429. The second mounting plate 427 is fixed to the ejection slide plate 424, and the third mounting plate 429 is on the top surface of the machine base 1. One end of the second spring 428 is connected to the second mounting plate 427, and the other end is connected to the third mounting plate 429.

[0094] When the ejector plate 424 is pushed horizontally by the fifth cam 421, the second mounting plate 427 moves horizontally along with the ejector plate 424, while the position of the third mounting plate 429 remains fixed, thereby stretching the second spring 428. As the fifth cam 421 continues to rotate until it leaves the ejector plate 424, the second spring 428 will immediately retract, thereby quickly pulling the ejector plate 424 back to its original position.

[0095] Furthermore, such as Figure 1 As shown, it also includes a conveying mechanism 8, which is disposed on the top of the machine base 1 and located on one side of the mold turntable 32. The conveying mechanism 8 is used to receive the egg tart shells pushed out by the ejection component 42.

[0096] The ejector component 42 ejects the egg tart shells from the pressing mold 31 to the conveyor mechanism 8, which can be a belt conveyor. The conveyor mechanism 8 transports the pressed egg tart shells to the next process.

[0097] Furthermore, such as Figure 8-12 As shown, it also includes an adsorption mechanism 9, which includes a first cylinder 901, a third slide block 902, a first slide rod 903, a suction cup seat 904, a negative pressure pipe 905, a limiting seat 906, a suction cup 907, a second cylinder 908, a fourth slide block 909, a second slide rod 910, an L-shaped connecting rod 911, and an air baffle 912.

[0098] The first cylinder 901 and the third slide block 902 are respectively fixed to the lower mounting plate 13. One end of the first slide rod 903 is connected to the piston rod of the first cylinder 901. The first slide rod 903 is slidably engaged with the third slide block 902. The top surface of the first slide rod 903 is provided with a guide step 913.

[0099] The suction cup base 904 is installed on the top surface of the machine base 1, and the suction cup base 904 is located below the mold turntable 32. The suction cup base 904 is provided with a third through hole 914 in the vertical direction, and the top surface of the suction cup base 904 is provided with an air baffle groove 915 communicating with the third through hole 914.

[0100] The upper end of the negative pressure tube 905 is inserted into the third through hole 914 and is slidably engaged with the third through hole 914. The lower end of the negative pressure tube 905 is inserted into the limiting seat 906. The suction cup 907 is disposed on the top of the negative pressure tube 905. The bottom of the negative pressure tube 905 is connected to an external negative pressure air source. The bottom of the limiting seat 906 is slidably engaged with the guide step 913. The guide step 913 drives the negative pressure tube 905 to slide up and down in the third through hole 914.

[0101] The second cylinder 908 and the fourth slide block 909 are installed on the bottom of the table 11 of the machine base 1. One end of the second slide rod 910 is connected to the piston rod of the second cylinder 908. The second slide rod 910 and the fourth slide block 909 are slidably engaged. One end of the L-shaped connecting rod 911 is connected to the second slide rod 910. The table 11 is provided with a clearance hole 16. The other end of the L-shaped connecting rod 911 extends upward and passes through the clearance hole 16. The air baffle 912 is fixed to the other end of the L-shaped connecting rod 911. The air baffle 912 is inserted into the air baffle groove 915. The air baffle 912 is used to move away from the top of the third through hole 914 when the negative pressure pipe 905 rises and to block the top of the third through hole 914 when the negative pressure pipe 905 falls.

[0102] When the die head 28 presses down, it comes into direct contact with the dough and applies pressure. Because the dough is light and has a certain degree of stickiness, it easily sticks to the die head 28. However, a carrier, such as an aluminum foil cup, stainless steel cup, aluminum cup, or iron cup, separates the dough from the pressing mold 31, so the dough sticks to the carrier but not to the pressing mold 31. To prevent the dough from sticking to the die head 28 after pressing, the surface of the die head 28 is usually very smooth to reduce the adhesion between the dough and the surface of the die head 28. However, even so, the dough will still have some... There is a certain probability that the dough will stick to the mold head 28 and detach from the pressing mold 31 when the mold head 28 moves upward. To solve this problem, the present invention innovatively sets up an adsorption mechanism 9. When the mold head 28 moves upward, the adsorption mechanism 9 adsorbs the carrier inside the pressing mold 31, thereby preventing the dough and carrier from moving upward with the mold head 28 and detaching from the pressing mold 31. Specifically, when the mold head 28 begins to move upward, the first cylinder 901 and the second cylinder 908 extend simultaneously. The second cylinder 908 pushes the air baffle 912 through the L-shaped rod, causing the top of the third through hole 914 to open. The first cylinder 901 pushes the first slide rod 903 to extend. The first slide rod 903 lifts the limiting seat 906 and the negative pressure tube 905 through the guide step 913, causing the suction cup 907 at the top of the negative pressure tube 905 to extend upward and adhere to the bottom surface of the carrier, thus holding the carrier in place. The adhesion between the dough and the carrier is greater than the adhesion between the dough and the mold head 28, so the dough and the carrier will remain inside the pressing mold 31, thus preventing the dough and the carrier from moving upward with the mold head 28. After the mold head 28 moves upward a certain distance and detaches from the dough, the first cylinder 901 and the second cylinder... Simultaneously, cylinder 908 retracts, with cylinder 901 pulling the first slide bar 903 back to its original position. The limiting seat 906 falls along the guide step 913 of the first slide bar 903, causing the suction cup 907 to detach from the carrier. At the same time, cylinder 908 pulls the air baffle 912 through the L-shaped rod to block the top of the third through hole 914, thus blocking the suction cup 907 and preventing negative pressure between the carrier and the suction cup seat 904. When the mold turntable 32 moves the pressed tart shell out of the pressing mechanism 2 by rotation, the tart shell will not tilt under the impact of the airflow.

[0103] Furthermore, the adsorption mechanism 9 also includes a guide tube 916 and a third spring 917. The guide tube 916 is sleeved on the top outer side of the negative pressure tube 905, and the bottom of the guide tube 916 is fixed to the bottom surface of the platform 11 by a flange. The top of the guide tube 916 passes through the platform 11 and is inserted into the bottom of the suction cup seat 904. The third spring 917 is sleeved on the outside of the negative pressure tube 905, and the upper end of the third spring 917 abuts against the flange of the guide tube 916, and the lower end abuts against the limiting seat 906.

[0104] By setting the guide tube 916, the negative pressure tube 905 can be better guided, giving the negative pressure tube 905 a longer guide surface, thereby reducing the swaying of the negative pressure tube 905 during up and down movement, and making the negative pressure tube 905 more stable during up and down movement; the third spring 917 can provide a downward elastic force to the limiting seat 906. When the first cylinder 901 retracts, the limiting seat 906 moves downward under the elastic force of the third spring 917 and sticks tightly to the surface of the guide step 913; in addition, the third spring 917 can also cause the limiting seat 906 to drive the negative pressure tube 905 to pull the suction cup 907 out of the bottom of the carrier, so that the suction cup 907 can quickly detach from the carrier.
