[0023] This application discloses a tea packaging machine with a screening effect. The tea leaves are placed on a screening box, and the leaves move along an inclined screen plate. Because the screen plate has perforations, fine particles of impurities in the tea leaves fall through the perforations to the bottom of the screening box, thus completing the initial screening of the tea leaves. A second push rod component controls a baffle to prevent the tea leaves from flowing out of the screening box. Furthermore, a scraper in the mixing assembly moves laterally in conjunction with a second screw component, thus agitating the tea leaves and completing a second screening. The scraper and the second push rod... The components are connected, enabling the scraper to move vertically. This prevents the scraper from pushing and accumulating tea leaves on one side during movement, thus avoiding the accumulation of impurities inside the tea leaves. The sieve box is connected to the support seat installed on the first screw component. Therefore, after sieving, the sieve box can be moved to the main body of the packaging machine by the first screw component for further sieving. After the tea leaves enter the main body of the packaging machine, the raw tea leaves can be sieved again. Through the cooperation of the mixing component and the sieve plate, the sieving operation of the tea leaves can be realized, thereby improving the processing efficiency of the tea leaves.

[0044] Reference Figures 1-4 A tea packaging machine with a sieving effect includes a packaging machine body 1 and a sieving box 2. The packaging machine body 1 is used to package tea, while the sieving box 2 is used to sieve the tea. The packaging machine body 1 has a feeding box 11, and displacement components 3 are respectively arranged on both sides of the feeding box 11. The displacement components 3 include a support 31, which is arranged on the outside of the feeding box 11. A first lead screw component 32 is rotatably arranged on the support 31 and a rotating motor 33 is installed on it. The rotating motor 33 is a servo drive motor in the prior art. The rotating motor 33 and the first lead screw component 32 are connected by a coupling. A bearing seat 34 is installed on the first lead screw component 32. The bottom of the feeding box 11 is respectively installed on two sets of bearing seats 34. The displacement components 3 drive the sieving box 2 to move its position, so that the sieving box 2 is closer to or farther away from the packaging machine body 1. This allows for adjustment according to the tea to be packaged, avoiding the problem of waste of resources caused by the tea having to be sieved again.

[0045] The screening box 2 has a receiving cavity 21. A discharge hopper 22 communicating with the receiving cavity 21 is provided on one side of the screening box 2. Through the cooperation of the first screw component 32 and the bearing seat 34, the screen plate 4 is inclinedly installed in the receiving cavity 21, which is close to or away from the top of the feeding box 11. One end of the screen plate 4 is located in the discharge hopper 22. The receiving cavity 21 serves as the main screening cavity, which is used to contain tea raw materials and screening components, and provides screening operation space. Through the cooperation of the inclined screen plate 4 and the discharge hopper 22, the tea leaves slide along the inclined direction under the action of gravity, and the tea leaves are quickly discharged. Since the screen plate 4 has screen holes, small tea dregs can fall off the screen plate 4 during the flow, while large whole tea leaves are discharged along the discharge hopper 22.

[0046] A mixing assembly 5 is provided inside the accommodating cavity 21. The mixing assembly 5 includes a second lead screw component 51, which is movably installed on the inner wall of the accommodating cavity 21. The other end extends to the outside of the screening box 2 and is equipped with a drive motor 52. The drive motor 52 is a servo drive motor in the prior art. The output end of the drive motor 52 is connected to the second lead screw component 51 through a coupling. A support base 53 is installed on the second lead screw component 51. A support plate 531 is provided on one side of the support base 53. A first push rod component 54 is provided on the support plate 531. The piston end of the first push rod component 54 passes through the support plate 531 and is equipped with a scraper plate 541. The scraper plate 541 moves close to the surface of the screen plate 4 and can remove tea particles stuck on the screen plate 4 to prevent blockage. At the same time, the stirring action loosens the accumulated tea and improves the screening pass rate.

[0047] The screening box 2 is also equipped with a second push rod component 6 located above the discharge hopper 22. The discharge hopper 22 has a slot 221. A baffle 61 is installed on the piston end of the second push rod component 6. Through the cooperation of the second push rod component 6, the baffle 61 passes through or moves away from the slot 221. The baffle 61 is used to control the discharge rhythm of the screened material and to discharge the tea leaves in the screening box 2 in coordination with the screening progress of the screening box 2 or subsequent processes.

[0048] Based on the above structure, by placing the tea raw materials requiring sieving into the sieving box 2, and controlling the baffle 61 through the second push rod component 6, the baffle 61 is embedded into the slot 221 of the discharge hopper 22 and abuts against the inner wall end face of the discharge hopper 22. When the tea in the sieving box 2 moves along the inclined angle of the sieve plate 4, because the sieve plate 4 has sieve holes, when the tea particles are smaller than the size of the sieve holes, they will fall through the sieve holes to the bottom of the sieving box 2, thus achieving preliminary sieving of the tea. Furthermore, since the sieving box 2 has a mixing component 5, the scraper 541 in the mixing component 5 is connected to the first push rod component 54. Through the cooperation of the first push rod component 54, the scraper 541 can be driven to contact the tea material. Since the support plate 531 on which the first push rod component 54 is placed is located on the support seat 53 connected to the second screw component 51, the tea material is sieved. The rotation of the drive motor 52 enables the second lead screw component 51 to move the support base 53 in the direction of rotation of the second lead screw component 51. During the movement, the scraper plate 541 moves, thereby agitating the tea leaves and removing some of the fine particles accumulated in the tea leaves, thus achieving a second screening operation. Finally, with the cooperation of the first lead screw component 32 and the rotating motor 33, the screening box 2 is moved to the top of the dispensing machine body 1. With the cooperation of the second push rod component 6, the baffle 61 is moved away from the trough 221, allowing the tea leaves in the screening box 2 to flow into the dispensing machine body 1 for dispensing. Through the cooperation of the sieve plate 4 and the mixing component 5 in the screening box 2, the screening and dispensing of tea materials can be carried out on one machine, solving the problem that the existing screening and dispensing require two different machines, resulting in long turnaround time and low processing efficiency.

[0049] In one embodiment, reference is made to Figure 1 and Figure 4 The support seat 34 has a groove 341, within which a limiting groove is provided. Several limiting grooves are provided and spaced apart along the length of the groove 341. An elastic element 7 is provided on the limiting groove, and a buffer pad 71 is connected to the other end of the elastic element 7. The elastic element 7 is a pressure spring in the prior art, and the buffer pad 71 is made of rubber. The buffer pad 71 is connected to the bottom of the screening box 2. The elastic element 7 and the buffer pad 71 form a buffer structure, which can buffer and reduce vibration of the screening box 2. During the screening process, the screening box 2 will vibrate. This structure can reduce the impact of vibration on the support seat 34 and the entire dispensing machine body, while avoiding direct collision between the screening box 2 and the support seat 34 due to excessive vibration and damage. This reduces the noise and wear caused by vibration of the equipment and extends the service life of the equipment.

[0050] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 6A snap-fit ​​seat 211 is provided on one side of the receiving cavity 21, and a snap-fit ​​seat 2111 is provided on the snap-fit ​​seat 2111. A through groove 23 is provided on the other side of the screening box 2 corresponding to the snap-fit ​​groove 2111. Through the cooperation of the snap-fit ​​seat 211 and the through groove 23, when the screen plate 4 passes through the through groove 23 and is located in the receiving cavity 21, one end of the screen plate 4 is embedded in the snap-fit ​​groove 2111, so that the screen plate 4 is installed in the screening box 2. This can accurately position the screen plate 4 in the screening box 2, ensure that the screen plate 4 remains stable during the screening process, and enable flexible installation of the screen plate 4. This facilitates the subsequent replacement or maintenance of the screen plate 4. At the same time, screen plates 4 with different mesh sizes can be replaced according to the actual situation to adjust the screening accuracy.

[0051] In one embodiment, reference is made to Figure 1 and Figure 2 A vibration motor 8 is installed on the outside of the screening box 2. The vibration motor 8 is located between two sets of supports 31. The vibration motor 8 provides the power required for vibration of the screening box 2, so that the tea leaves in the screening box 2 shake under the action of vibration, thereby causing the broken leaves attached to the tea leaves to fall off by shaking. Thus, the broken leaves can be better screened through the screen holes of the screen plate 4, further improving the screening efficiency.

[0052] In one embodiment, reference is made to Figures 1-3 A collection box 24 is movably installed at the bottom of the accommodating cavity 21. The collection box 24 has a collection port that communicates with the accommodating cavity 21. The collection box 24 is located below the sieve plate 4. Part of the collection box 24 is located outside the sieve box 2 and is equipped with a handle 241. The collection box 24 collects tea leaves after being screened by the sieve plate 4 through the collection port. The handle 241 makes it easy to remove the collection box 24 from the sieve box 2, which is convenient for cleaning and collecting tea leaves.

[0053] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 6 The inner wall of the slot 2111 is provided with a magnetic layer 2112, and the side of the screen plate 4 facing the slot 2111 is provided with a magnetic part 41. Through the cooperation of the magnetic part 41 and the magnetic layer 2112, the screen plate 4 is magnetically connected to the mounting base 211. The magnetic adsorption effect further enhances the connection stability between the screen plate 4 and the mounting base 211. At the same time, during the screening process, it can prevent the screen plate 4 from loosening or shifting due to vibration, ensuring that the position of the screen plate 4 is fixed during the screening process, thus improving the accuracy and stability of screening.

[0054] In one embodiment, reference is made to Figure 1 and Figure 5The scraper plate 541 has inclined ends 5411 at both ends. The two sets of inclined ends 5411 form pointed tips on the scraper plate 541, which abut against the end face of the sieve plate 4. The scraper plate 541 can scrape the tea leaves on the sieve plate 4 during the sieving process, preventing tea leaves from accumulating on the sieve plate 4 and ensuring that the tea leaves can pass evenly through the sieve holes of the sieve plate 4. The pointed tips formed by the inclined ends 5411 can more effectively scrape the tea leaves and also play a guiding role in the scraping process.

[0055] In one embodiment, reference is made to Figures 1-3 The other end of the screen plate 4 is provided with a limiting plate 42. When the screen plate 4 is embedded in the slot 2111, the limiting plate 42 is located outside the screen box 2. The size and area of ​​the limiting plate 42 are larger than the size and area of ​​the through slot 23. A handle groove is provided on the side of the limiting plate 42 away from the through slot 23. The limiting plate 42 plays a limiting role to prevent the screen plate 4 from being excessively inserted into the screen box 2 during installation. At the same time, the handle groove is also convenient for operators to operate when installing and disassembling the screen plate 4.

[0056] In one embodiment, reference is made to Figure 1 A support rod 311 is provided at the bottom of the support 31. The other end of the support rod 311 abuts against the top of the main body 1 of the dispensing machine. The support rod 311 provides support for the support 31, enhances the stability of the support 31, improves the overall stability of the equipment, and reduces shaking and displacement caused by vibration or external force.
