Description

Technical Field

[0001] This utility model relates to the technical field of egg tart crust production equipment, and in particular to a turntable structure for an automatic egg tart crust production equipment. 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. The manual process is tedious. However, in current egg tart shell production equipment, the pressing molds are usually placed on a turntable. The turntable rotates, moving each pressing mold sequentially under the mold head for pressing. The turntable is usually directly driven by a motor. Because the pressing molds need to pause temporarily under the mold head during the pressing process, the motor needs to be started and stopped frequently, resulting in a short motor lifespan and high maintenance costs.

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] This embodiment describes a turntable structure for an automated egg tart crust production device, such as... Figure 1-5 As shown, it includes:

[0030] Machine base 1, the top surface of which is formed with a table surface 11;

[0031] A turntable mechanism 3 includes a mold turntable 32, a rotating shaft 34, and a shifting turntable 35. The mold turntable 32 is mounted on the top surface of the table 11. The mold turntable 32 is provided with pressing molds 31, which are equidistantly arranged around the axis of the mold turntable 32. The upper end of the rotating shaft 34 passes through the table 11 and is fixedly connected to the mold turntable 32, and the lower end of the rotating shaft 34 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.

[0032] The fork limiting assembly 36 is used to release the limiting post 352 when the shifting post 351 is moved to make the shifting turntable 35 rotate, and to limit the limiting post 352 when the shifting post 351 is moved to the position.

[0033] The drive mechanism 5 is connected to the shift fork limiting assembly 36 to drive the shift fork limiting assembly 36.

[0034] In practical use, a pressing and forming mechanism is installed above the table 11 via a bracket 12. The pressing and forming mechanism performs pressing by reciprocating up and down the drive die head. The mold turntable 32 is used to support the pressing die 31. The mold turntable 32 is connected to the shift turntable 35 via a rotating shaft 34. Therefore, when the shift turntable 35 rotates, the rotating shaft 34 can drive the mold turntable 32 to rotate synchronously. The drive mechanism 5 drives the cam 37 to rotate. The cam 37 drives the shift fork limit assembly 36 to sequentially move the shift column 351, so that the shift turntable 35 can rotate a certain angle each time. This drives the mold turntable 32 to move the pressing die 31, which is loaded with the carrier and dough, to the pressing and forming mechanism for pressing. After pressing, the mold turntable 32 removes it from the pressing and forming mechanism and moves the next pressing carrier. The pressing continues below the pressing and forming mechanism, thus continuously pressing out egg tart crusts. Furthermore, when the fork 367 limiting mechanism moves to the next shifting post 351, it needs to first disengage from the previous shifting post 351 and move to the position of the next limiting post 352. During this period, the shifting turntable 35 is prone to displacement due to vibration, inertia, and other factors, causing the pressing mold 31 and the die head to not be fully aligned, affecting product quality. Therefore, by setting a limiting post 352 on the bottom surface of the shifting turntable 35, when the fork 367 limiting mechanism leaves the shifting post 351, it limits the limiting post 352, thus keeping the shifting turntable 35 stationary. This ensures that the pressing mold 31 and the die head are fully aligned, thereby improving product quality and yield.

[0035] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, a lower mounting plate 13 is fixedly provided below the top surface of the machine base 1. The lower mounting plate 13 has a through hole 14, and a bearing 15 is installed in the through hole 14. The bearing 15 is rotatably engaged with the rotating shaft 34. The lower end of the rotating shaft 34 passes through the lower mounting plate 13 and is fixedly connected to the shifting turntable 35.

[0036] The cooperation between the rotating shaft 34 and the bearing 15 not only limits the lower end of the rotating shaft 34, making the rotating shaft 34 more stable when rotating, but also constrains both the upper and lower ends of the rotating shaft 34, thus making it more stable when rotating and reducing shaking.

[0037] Furthermore, such as Figure 3As 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 cam frame 365, a cam 37, 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 shift 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. The cam 37 is drively connected to the drive mechanism 5. The cam 37 is connected to the cam frame. The inner wall of 365 is fitted; 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 from the relief groove 3662 when the shift fork 367 moves the shifting column 351.

[0038] When cam 37 rotates under the drive of drive mechanism 5, cam 37 drives cam frame 365 to slide along second slide block 364. Since second slide block 364 is mounted on lower slide plate 363, second slide block 364 can move in a direction perpendicular to its extension. Therefore, cam frame 365 can move cyclically in a plane according to a certain arc-shaped closed loop trajectory under the drive of cam 37, so as to sequentially actuate each shifting column 351, causing shifting turntable 35 to rotate intermittently; lower slide plate 36 Driven by cam 37, the lower slide plate 363 moves reciprocally 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 move reciprocally, 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 next shift post 351 moved by the shift fork 367... The limiting post 352 between the two ends enters the limiting arm 366 from the relief groove 3662 and slides into the limiting slide 3661. As the shift fork 367 and the limiting arm 366 retract, the two sides of the limiting slide 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... 52 also moves into the clearance groove 3662. As the shift fork 367 moves the shifting post 351, the limiting post 352 also moves away from the clearance groove 3662 and the limiting arm 366 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 mold head during the pressing process, thereby improving the quality of the product.

[0039] Furthermore, such as Figure 1 and Figure 2 As shown, a turntable bearing 33 is provided between the mold turntable 32 and the table surface 11.

[0040] By setting the turntable bearing 33, not only can the turntable be supported, but friction between the bottom surface of the mold turntable 32 and the table surface 11 can also be avoided, which would cause wear and make the mold turntable 32 rotate more smoothly.

[0041] 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.

[0042] 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.

[0043] Furthermore, such as Figure 5 As shown, the limiting arm 366 includes a base plate 3663 and limiting plates 3664 disposed on both sides of the base plate 3663. The limiting slide 3661 is formed between the two limiting plates 3664. A gap is left between the limiting plates 3664 and the sliding plate 363 to form the clearance groove 3662. The end of the base plate 3663 away from the limiting plates 3664 is fixed to the sliding plate 363.

[0044] The base plate 3663 serves as a connector to fix the limiting plate 3664 so that a limiting slide 3661 can be formed between the two limiting plates 3664.

[0045] Furthermore, such as Figure 2 As shown, the drive mechanism 5 includes a motor 51, a reduction gearbox 52, a transmission shaft 53, and a reversing gearbox 54; a bracket 12 is provided on the top surface of the platform 11, the reduction gearbox 52 is fixedly installed on the bracket 12, the motor 51 is installed at the input end of the reduction gearbox 52, the upper end of the transmission shaft 53 is connected to the output end of the reduction gearbox 52 through a bevel gear transmission, the lower end of the transmission shaft 53 is connected to the input shaft of the reversing gearbox 54 through a bevel gear transmission, and the output shaft of the reversing gearbox 54 is connected to the cam 37 through a transmission.

[0046] This arrangement allows the motor 51 to be placed above the platform 11, making maintenance and repair of the motor 51 more convenient. The reversing gearbox 54 allows the fork 367 limiting mechanism to move forward relative to the drive shaft 53, thus getting closer to the turntable mechanism 3. The fork 367 and limiting arm 366 can then move and limit the shifting turntable 35 with a shorter stroke, resulting in faster and more flexible operation.
