Tea ingredients include catechins, cholesterin, caffeine, inositol, folic acid, and pantothenic acid, which are beneficial to health. Tea beverages made from tea are one of the three major beverages in the world. Tea originated in China and was first used as a sacrifice. However, it has been used as a vegetable since the late Spring and Autumn Period, and developed into a medicinal use in the middle of the Western Han Dynasty. It was not until the late Western Han Dynasty that it developed into a high-end beverage for the palace. It was not until the Western Jin Dynasty that it became popular among the people as an ordinary beverage.

[0003] Tea repackaging is to place tea leaves in individual packaging bags. Each bag usually contains an appropriate amount of tea leaves, which is convenient for single use or carrying. Repackaging can better maintain the freshness of tea leaves. The packaging is independently sealed to prevent the tea leaves from contacting with air and slow down the oxidation of tea leaves. Repackaging is convenient for users to use on demand. Users can choose the appropriate type and quantity of tea leaves according to their own needs.

[0004] In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. The existing bulk tea is inevitably mixed with some debris and impurities during the production process. When packaging the tea, manual sorting is often required, which is very inconvenient; 2. When packaging the tea, there are often requirements for the specifications of the independent packaging, which requires the use of an automatic packaging machine with the function of quantitative feeding.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0022] In this embodiment, Figure 2 and Figure 5As shown, the transmission mechanism 2 is composed of a transmission main shaft 201, a transmission slave shaft 202, a driving motor 203 and a transmission belt 204, wherein the transmission main shaft 201 and the transmission slave shaft 202 respectively penetrate the inner walls of the left and right sides of the baffle 1 horizontally, and the transmission belt 204 is also sleeved on the outer wall of the shaft of the transmission main shaft 201 and the transmission slave shaft 202, and one end of the transmission main shaft 201 is plugged into the output end of the driving motor 203; it should be noted that, in the process of automatic packaging of tea leaves by the operator, it is necessary to first place a number of packaging boxes 3 on the upper surface of the transmission belt 204, and then start The driving motor 203 is driven, so that the output end of the driving motor 203 rotates rapidly and drives the connected transmission main shaft 201 to start rotating. At the same time, the transmission main shaft 201 transmits the rotational force it receives to the transmission slave shaft 202 at the other end through the transmission belt 204, so that the transmission main shaft 201 and the transmission slave shaft 202 can rotate at the same time, thereby driving the transmission belt 204 on which the two are mounted to continuously move around the axis. In this process, the packaging boxes 3 placed on the top of the transmission belt 204 are transmitted one by one to the bottom of the discharge pipe 10, completing the unloading and packaging of the tea leaves.

[0023] In this embodiment, Figure 2 and Figure 3 As shown, the inner wall of the screening box 5 is provided with a screening plate 501, and a vibration motor 502 is threadedly installed on the left and right sides of the bottom of the screening plate 501; it should be noted that before quantitative packaging of tea, the operator is required to pour the bulk tea from the hopper 6 into the interior of the screening box 5, and at the same time, start the vibration motor 502 threadedly installed on the bottom of the screening plate 501 through an external controller, so that the vibration motor 502 drives the entire screening plate 501 to vibrate continuously, and at the same time, when the tea enters the screening box 5 and falls on the surface of the screening plate 501, it can be vibrated and screened on the surface of the screening plate 501 under the drive of the vibration motor 502, because the surface of the screening plate 501 is provided with sieve holes, it can directly intercept impurities mixed in the tea, and then allow pure tea to pass through the sieve holes and fall into the drop barrel 7 directly below.

[0024] In this embodiment, Figure 2 and Figure 4As shown, the baffle mechanism 8 is composed of a baffle plate 801, a hydraulic push rod 802 and a rotating shaft 803, wherein the baffle plate 801 is arranged on the inner wall of the blanking barrel 7, and one side of the bottom of the baffle plate 801 is also fixedly connected to the driving end of the hydraulic push rod 802, and at the same time, a rotating shaft 803 is horizontally penetrated on one side of the inner part of the baffle plate 801; it should be noted that when the pure tea leaves that have undergone vibration screening fall into the blanking barrel 7 through the sieve holes opened on the surface of the screening plate 501, the tea leaves will directly fall on the top of the baffle plate 801 arranged on the inner wall of the blanking barrel 7, and the amount of tea leaves will continue to accumulate. At the same time, the weight sensor 9 threadedly installed on the bottom of the baffle plate 801 will run at the same time. After the tea leaves on the top of the baffle plate 801 accumulate to a certain weight, it will be immediately sensed by the weight sensor 9. At the same time, the hydraulic push rod 802 arranged on one side of the bottom of the baffle plate 801 starts to start and shortens its driving end, thereby driving the height of one side of the baffle plate 801 to drop, so that the other side of the baffle plate 801 rotates around the rotating shaft 803, and then the baffle plate 801 is flipped over, so that the tea leaves accumulated on the top of the baffle plate 801 tilt and slide into the discharge pipe 10 just below, completing the quantitative unloading.

[0025] In this embodiment, Figure 2 and Figure 4 As shown, the material blocking mechanism 8 and the weight sensor 9 together constitute a weighing mechanism; it should be noted that when automatically packaging tea leaves, it is often necessary to ensure that the weight of the sub-packaging is the same, and this requires the automatic unloading device to be able to perform quantitative operations on the tea leaves by itself. In the automatic packaging machine in the utility model, a weighing mechanism is designed, which is completed by the cooperation of the weight sensor 9 and the material blocking mechanism 8. The specific operation is that when the tea leaves fall to the top of the material blocking plate 801 of the material blocking mechanism 8, the material blocking plate 801 always remains in a parallel state, blocking the channel between the drop barrel 7 and the discharge pipe 10, and after the tea leaves on the top of the material blocking plate 801 accumulate to a certain weight, they will be sensed by the weight sensor 9 in time, and then the hydraulic push rod 802 is driven to make the material blocking plate 801 rotate and flip around the rotating shaft 803, thereby dumping the preset weight of tea leaves into the discharge pipe 10 directly below to complete quantitative unloading.

[0026] In this embodiment, Figure 1As shown, the blanking barrel 7 is an inverted cone-shaped barrel with a larger upper part and a smaller lower part. It should be noted that the tea leaves will pass through the vibration screening of the screening plate 501 in turn, and fall to the top of the baffle plate 801 arranged inside the blanking barrel 7. After reaching the preset weight, it will be promptly sensed by the weight sensor 9, and at the same time, the hydraulic push rod 802 will shorten its driving end, thereby driving the baffle plate 801 to flip, so that the preset weight of tea leaves will be poured into the discharge pipe 10 directly below. During this period, the tea leaves will fall downward and enter the lower half of the blanking barrel 7. At this time, the inverted cone-shaped barrel can make the tea leaves slide toward the middle along the barrel wall, thereby concentrating into the discharge pipe 10 arranged at the bottom of the blanking barrel 7, and then be discharged from the discharge pipe 10 to the opening of the packaging box 3 previously transferred to the bottom thereof, completing the packaging without being scattered everywhere.

[0027] The use method and advantages of the utility model: When the automatic packaging machine capable of quantitative feeding is used, the working process is as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, first, the operator places several packaging boxes 3 on the upper surface of the conveyor belt 204, and then pours the bulk tea leaves from the hopper 6 into the inside of the screening box 5, and starts the vibration motor 502, so that the vibration motor 502 drives the screening plate 501 to vibrate. At the same time, the tea leaves are vibrated and screened on the surface of the screening plate 501, and fall through the sieve holes to the top of the baffle plate 801 arranged inside the blanking tube 7 directly below. After accumulating to a certain weight, the weight sensor 9 will immediately sense it. At the same time, the hydraulic push rod 802 starts to start, shortens its driving end, and drives the baffle plate 801 to flip around the rotating shaft 803, so that the tea leaves accumulated on the top of the baffle plate 801 tilt and slide into the discharge pipe 10 directly below. At the same time, the transmission mechanism 2 starts to run and conveys the packaging box 3 to the bottom of the discharge pipe 10 to complete the quantitative unloading.
