Description

Technical Field

[0001] This utility model relates to the field of sesame mooncake production technology, specifically a screening device for sesame mooncakes. Background Technology

[0002] Mooncakes are one of the most famous traditional Chinese pastries, a traditional food for the Mid-Autumn Festival. The round shape of the mooncake symbolizes family reunion and harmony. Mooncakes are made of flour, sugar, sesame seeds, and various fillings. They have a soft, sweet and delicious taste. In the production process of mooncakes, sesame seeds need to be ground and then screened to obtain sesame powder. The sesame powder is then mixed with other ingredients to make the crust. Therefore, the screening process is particularly important.

[0003] Chinese patent discloses a sesame screening device for sesame paste production (authorization announcement number CN209205788U). The device feeds sesame seeds into a screening box through an inlet, where they fall evenly through holes in a baffle plate. A blower removes stalks and leaves from the sesame seeds. When the sesame seeds land on the upper surface of the sieve plate, a vibrating motor activates, causing the sieve plate to vibrate. The sesame seeds then flow along the mesh of the sieve plate into a collection box, while sand and gravel mixed in with the sesame seeds are discharged through the air outlet into a waste box. However, this device only uses a single sieve plate to screen the sesame seeds. While this method can screen larger impurities, it is difficult to screen smaller impurities, resulting in insufficient screening accuracy and hindering the improvement of raw material screening efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sesame mooncake screening device, comprising a base, a collection box fixedly connected to the top of the base, and a first vertical rod and a second vertical rod fixedly connected to the top of the base. A traveling mechanism is installed on the first and second vertical rods. The traveling mechanism includes a servo motor, a first adjusting block, and a second adjusting block. A bidirectional lead screw is fixedly connected to the drive end of the servo motor. One end of the bidirectional lead screw is rotatably connected to an installation block via a bearing. The external threads of the bidirectional lead screw are fitted with the first and second adjusting blocks. A first bracket and a second bracket are hinged to the top and bottom of the first adjusting block, respectively. A third bracket and a fourth bracket are hinged to the top and bottom of the second adjusting block, respectively. A first limiting frame is hinged to one end of the first bracket and one end of the second bracket. A second limiting frame is hinged to one end of the third bracket and one end of the fourth bracket. A first fastening rod is fixedly connected to each of the two second limiting frames. A second fastening rod is fixedly connected to each of the two first limiting frames. A first screening box is fixedly connected to one end of the first fastening rod, and a second screening box is fixedly connected to one end of the second fastening rod.

[0006] Optionally, motors are fixedly connected to the bottom center of the first screening box and the bottom center of the second screening box, and the drive ends of the two motors pass through the first screening box and the second screening box respectively and are fixedly connected to a stirring plate.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 4 This utility model provides a screening device for sesame mooncakes, including a base 1, a collection box 2 fixedly connected to the top of the base 1, and a first vertical rod 3 and a second vertical rod 4 fixedly connected to the top of the base 1.

[0020] A traveling mechanism 5 is installed on the first vertical rod 3 and the second vertical rod 4. The traveling mechanism 5 includes a servo motor 51, a first adjusting block 52, and a second adjusting block 53. A bidirectional lead screw 511 is fixedly connected to the drive end of the servo motor 51. One end of the bidirectional lead screw 511 is rotatably connected to a mounting block 512 via a bearing. The first adjusting block 52 and the second adjusting block 53 are threaded onto the external threads of the bidirectional lead screw 511. A first bracket 521 and a second bracket 522 are hinged to the top and bottom of the first adjusting block 52, respectively. A third bracket 531 and a fourth bracket 532 are hinged to the top and bottom of the second adjusting block 53, respectively. A first limiting frame 54 is hinged to one end of the first bracket 521 and one end of the second bracket 522. A first limiting frame 54 is hinged to one end of the third bracket 531 and one end of the fourth bracket 532. Each end of the bracket 532 is hinged to a second limiting frame 55. A first fastening rod 56 is fixed to each of the two second limiting frames 55. A second fastening rod 57 is fixed to each of the two first limiting frames 54. A first screening box 58 is fixed to one end of the first fastening rod 56, and a second screening box 59 is fixed to one end of the second fastening rod 57. Motors 581 are fixed to the bottom center of both the first and second screening boxes 58 and 59. The drive ends of the two motors 581 pass through the first and second screening boxes 58 and 59 respectively and are fixed to a stirring plate 582. Both first limiting frames 54 are slidably fitted outside the first vertical rod 3, and both second limiting frames 55 are slidably fitted outside the second vertical rod 4. A servo motor 51 is fixed to the first vertical rod. 3. Mounting block 512 is fixed to the second vertical rod 4. Multiple sets of first filter holes are evenly distributed at the bottom of the first screening box 58, and multiple sets of second filter holes are evenly distributed at the bottom of the second screening box 59. The diameter of the first filter holes is larger than that of the second filter holes, and the diameter of the first screening box 58 is smaller than that of the second screening box 59. This ensures that the raw materials in the first screening box 58 fall into the second screening box 59 during the screening process. The center point of the first screening box 58 and the center point of the second screening box 59 are on the same vertical line. The lengths of the first support 521, second support 522, third support 531, and fourth support 532 are all equal, and their inclination angles are also equal. The traveling mechanism 5 can drive the first support 521, the second support 522, the third support 531, and the fourth support 532 to swing. Through the swinging of these supports, not only can the two first limiting frames 54 move relative to or in opposite directions, but the two second limiting frames 55 can also move relative to or in opposite directions. This, in turn, causes the first screening box 58 and the second screening box 59 to move relative to or in opposite directions, facilitating the shaking of the raw materials within the first and second screening boxes 58 and 59. Utilizing this dual-shaking filtration method, not only larger impurities can be screened, but also smaller impurities can be screened, resulting in finer raw material screening and improved screening efficiency.Furthermore, while the first screening box 58 and the second screening box 59 move up and down, the motor 581 can also drive the stirring plate 582 to rotate within the first screening box 58 and the second screening box 59, further improving the screening effect of the raw materials.

[0021] Among them, the servo motor 51 is model ACSM110-G04030LZ, and the motor 581 is model YE2.

[0022] Working principle: When using this device, sesame seeds are poured into the first screening box 58. At this time, the servo motor 51 and the electric motor 581 are turned on. The forward and reverse rotation of the servo motor 51 drives the bidirectional lead screw 511 to rotate in both directions. Through the forward and reverse rotation of the bidirectional lead screw 511, the first adjusting block 52 and the second adjusting block 53 can be moved relative to each other and in opposite directions. This, in turn, can drive the first support 521, the second support 522, the third support 531, and the fourth support 532 to move. Since the two first limiting frames 54 are slidably sleeved on the outside of the first vertical rod 3, and the two second limiting frames 55 are slidably sleeved on the outside of the second vertical rod 4, the movement of the first support 521, the second support 522, the third support 531, and the fourth support 532 can drive the first adjusting block 521, the second support 522, the third support 531, and the fourth support 532 to move. The fastening rod 56 and the second fastening rod 57 move relative to and in opposite directions, thereby driving the first screening box 58 and the second screening box 59 to move relative to and in opposite directions. While the first screening box 58 and the second screening box 59 are moving up and down, the motor 581 is turned on, which drives the stirring plate 582 to rotate, so as to continuously stir the raw materials in the first screening box 58 and the second screening box 59. The qualified raw materials in the first screening box 58 can fall into the second screening box 59 through the first filter hole at the bottom. As the second screening box 59 continues to shake, the raw materials in the second screening box 59 can be discharged through the second filter hole at the bottom and finally fall into the collection box 2 below for collection. Impurities in the raw materials remain in the first screening box 58 and the second screening box 59.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
