Description

Technical Field

[0001] The invention belongs to the technical field of brick tea production equipment and relates to an online tea filling device. Background Art

[0002] Green brick tea is a specialty industry in Xianning, Hubei Province, and has a high reputation in the industry. The existing brick tea production line generally includes the following steps: weigh the inner tea, middle tea and surface tea respectively, and place them in three tea boxes respectively. After continuous steaming in the tea steaming area, the three types of tea in the three tea boxes are sequentially introduced into the tea brick mold to form a three-layer structure. After pressing and molding, the tea brick blank is demoulded. The current brick tea production line has the following defects:

[0003] 1. A large number of tea boxes need to be operated online and arranged in order to facilitate the loading of inner tea, middle tea and surface tea, and then steamed separately and introduced into molds after steaming. That is, there are tea box circulation lines and mold circulation lines, and the structure is complicated.

[0004] 2. The humidity of tea leaves after steaming is very high. During the process of introducing tea leaves into the mold, some tea leaves adhere to the inner wall of the tea box, causing waste of tea leaves and requiring an additional cleaning process for the tea box. Furthermore, tea leaves are fragile after steaming, and the integrity of the tea leaves may be easily affected during the process of introducing tea leaves into the mold.

[0005] 3. In order to improve the cooking efficiency and realize continuous production, the inner tea, the surface tea and the middle tea are cooked in the same steamer, which may easily cause the middle tea to be overcooked. In fact, the cooking degree of the middle tea should be less than that of the inner tea and the surface tea to a certain extent, because the inner tea and the surface tea need to be embossed with patterns and the surface of the finished tea bricks needs to be smooth and clean, so the inner tea and the surface tea need to be cooked more thoroughly. Under ideal conditions, the inner tea and the surface tea need to be steamed for a longer time. However, in the prior art, because they are in the same steamer and the cooking time of each tea box is the same during continuous operation, the middle tea is overcooked.

[0006] 4. The existing tea brick mold needs to be manually disassembled, and its structure is complicated, and disassembling the mold wastes a lot of time. Summary of the invention

[0007] The purpose of the present invention is to provide an online tea filling device in view of the above-mentioned problems existing in the prior art. The technical problem to be solved by the present invention is how to improve the tea filling efficiency.

[0030] The third guide plate 5 is provided with a third avoidance opening at each tea pressing station 65 and brick discharging station 66;

[0031] The first guide plate 3, the second guide plate 4 and the third guide plate 5 are all ventilated mesh plates;

[0032] A steaming box 7 is provided at the tea steaming station 64, the middle of the steaming box 7 has a tea steaming cavity, and both ends of the steaming box 7 have a material passage for allowing the tea brick mold 2 to pass through; steam is introduced into the tea steaming cavity;

[0033] An upper pressing plate and a lower pressing plate are provided at the tea pressing station 65, and the upper pressing plate and the lower pressing plate are driven by a first cylinder and a second cylinder respectively.

[0034] The production method comprises the following steps:

[0035] Circulation of the tea brick mold 2 on the tea brick assembly line: the tea brick mold 2 is removed at the end of the brick tea assembly line, and after cleaning, it is sent to the head end of the tea brick assembly line, so that the first guide plate 3 is inserted into the first guide groove 24, and the second guide plate 4 is inserted into the second guide groove 25 respectively, and the tea brick mold 2 at the head end of the tea brick assembly line is intermittently pushed to move, so that each tea brick mold 2 on the tea brick assembly line moves synchronously;

[0036] The inner tea is put into the tea brick mold 2 running to the inner tea feeding station 61: the third guide plate 5 covers the lower end opening of the inner tea frame 21, and the weighed inner tea is put into the inner tea frame 21 from top to bottom;

[0037] The intermediate tea is put into the tea brick mold 2 running to the intermediate tea feeding station 62: the third guide plate 5 covers the lower opening of the inner tea frame 21, the second guide plate 4 covers the lower opening of the intermediate tea frame 22, and the weighed intermediate tea is put into the intermediate tea frame 22 from top to bottom;

[0038] Put the noodle tea into the tea brick mold 2 running to the noodle tea feeding station 63: the third guide plate 5 covers the lower end opening of the inner tea frame 21, the second guide plate 4 covers the lower end opening of the middle tea frame 22, and the first guide plate 3 covers the lower end opening of the noodle tea frame 23, and the weighed noodle tea is put into the noodle tea frame 23 from top to bottom;

[0039] Steaming tea: When each tea brick mold 2 passes through the steam box 7, the inner tea, the middle tea and the surface tea are steamed synchronously;

[0040] Pressing tea: At the tea pressing station 65, the first cylinder and the second cylinder act synchronously to drive the upper pressing plate and the lower pressing plate to press the tea leaves into the middle tea frame 22. The tea leaves are pressed by multiple tea pressing stations 65 to form tea bricks, and preliminary cooling is performed during the forming process.

[0041] Bricking: demoulding the tea bricks at the bricking station 66;

[0042] Cleaning: Remove the tea brick mold 2 at the end of the tea brick assembly line, and after cleaning, install it to the head end of the tea brick assembly line.

[0043] A brick-discharging assembly is respectively provided at the four side walls of the middle tea frame 22. The brick-discharging assembly includes a mounting hole opened on the side wall of the middle tea frame 22. A brick-discharging roller 221 is rotatably connected in the mounting hole. The circumferential surface of the brick-discharging roller 221 has a straight matching surface 222. The mounting hole forms a rectangular notch at the inner side surface of the middle tea frame 22. The straight surface can block the notch when it is flush with the inner side surface of the middle tea frame 22. A rotating shaft 223 is fixedly provided in the brick-discharging roller 221, and a bevel gear 224 is fixedly connected to both ends of the rotating shaft 223; the four rotating shafts 223 form a quadrilateral structure on the middle tea frame 22, and the two bevel gears 224 located at the corners of the quadrilateral structure are meshed with each other so that each brick-discharging roller 221 can rotate synchronously.

[0044] The brick discharging roller 221 is made of silica gel.

[0045] Each side wall of the middle tea frame 22 is a vertical surface, and the side wall of the inner tea frame 21 and the side wall of the middle tea frame 22 form an inclination angle of 3 to 5 degrees.

[0046] A third cylinder is provided at the brick discharging station 66, and a brick discharging frame is fixedly provided on the push rod of the third cylinder. The brick discharging frame includes a support plate 81 and driving plates 82 symmetrically arranged at both ends of the support plate 81, and the driving plates 82 and the support plate 81 have an inclination angle of 95 to 100 degrees; when the third cylinder pushes the brick discharging frame upward, the two driving plates 82 can respectively abut against two brick discharging rollers 221 parallel to each other, and make each brick discharging roller 221 rotate synchronously.

[0047] Two steam delivery pipes are arranged in the steam box 7 , which are located at the top and bottom of the steam box 7 respectively. The steam delivery pipes are provided with a plurality of steam nozzles facing the middle of the steam box 7 .

[0048] The brick-discharging roller 221 made of silicone material has a certain elasticity. During the tea pressing process, since the force is parallel to the side wall of the middle tea frame 22, the extrusion force on the brick-discharging roller 221 is small, and the matching surface 222 can be flush with the side wall of the middle tea frame 22 to form a smooth mold cavity. During the rotation of the brick-discharging roller 221, since it has a certain elasticity, the tea brick can be squeezed out from top to bottom while protecting the side wall of the tea brick from damage. The reason why the tea brick can be squeezed out is that in the initial state, the matching surface 222 is flat with the side wall of the middle tea frame 22. After the brick-discharging roller 221 rotates, it will extend out of the side wall of the middle tea frame 22, so that the brick-discharging roller 221 is tightly pressed against the side wall of the tea brick. During the rotation of the brick-discharging roller 221, the tea brick moves in the middle tea frame 22, and then the tea brick is separated from the middle tea frame 22.

[0049] Since the side walls of the inner tea frame 21 are all wedge-shaped, the tea bricks can be easily separated.

[0050] When the tea brick mold 2 is taken out from the end of the tea brick assembly line and installed at the beginning of the tea brick assembly line, it is necessary to ensure that the matching surface 222 of each brick discharging roller 221 is flat with the side wall of the middle tea frame 22.

[0051] Each tea brick mold 2 can be moved online by the guide rail composed of the first guide plate 3, the second guide plate 4 and the third guide plate 5. The moving method is: the spacing between adjacent stations is equally divided into multiple sections, and the tea brick mold 2 moves a small section at a time, stops after moving to the specified position, and moves the same distance again after stopping for a period of time, and repeats this process. The process actions such as unloading, pressing tea and discharging bricks are all performed when the tea brick mold 2 is stopped.

[0052] When the tea brick mould 2 moves between multiple tea pressing stations 65, the second guide plate 4 can block the lower opening of the middle tea frame 22 to prevent tea leaves from falling out, until the second avoidance opening 41 at this position is directly opposite to the outlet of the middle tea frame 22, and then the tea brick mould 2 stops operating and continues to press tea.

[0053] The inner tea feeding station 61, the middle tea feeding station 62 and the surface tea feeding station 63 all include a lower hopper and a receiving hopper. The lower hopper is used to put the weighed tea leaves into the corresponding tea brick mold 2, while the receiving hopper can hold the tea residues that may fall out.

[0054] Since the inner tea, middle tea and surface tea are all in the tea brick mold 2 throughout the production line, there is no need to change the container for the tea leaves, which reduces the number of steps and the number of times the tea leaves are led out and loaded, thereby reducing the damage to the tea leaves during the container replacement process.

[0055] Because the tea brick mold 2 is isolated by the first guide plate 3, the second guide plate 4 and the third guide plate 5 after being loaded with the inner tea, the middle tea and the surface tea, during the tea steaming process, the three kinds of tea are distributed in three spaces and are steamed separately. Furthermore, the steam at the top of the steamer 7 is sprayed from top to bottom to the surface tea of ​​the tea brick mold 2, and the steam at the bottom of the steamer 7 is sprayed from top to bottom to the inner tea of ​​the tea brick mold 2, while the middle tea is not directly steamed by the steam. After being blocked by the inner tea and the surface tea, the steam intensity, temperature and humidity of the steam for steaming the middle tea are weakened, which can ensure that within the same steaming time, the inner tea and the surface tea have greater maturity and humidity than the middle tea, thereby overcoming the shortcoming of simultaneous tea steaming in the existing tea brick production process causing the middle tea to be over-ripe.

[0056] This solution can realize online brick discharging. The taken-out tea bricks are placed on a support plate 81. A linear motor can push the tea bricks on the support plate 81 onto a conveyor belt. After cooling again, trimming, stamping, packaging and other processes can be carried out.

[0057] In addition to guiding each tea brick mold 2, the first guide plate 3, the second guide plate 4 and the third guide plate 5 are respectively provided with a first avoidance opening 31, a second avoidance opening 41 and a third avoidance opening adapted to each process, so that the tea brick mold 2 can perform feeding, pressing and bricking of three kinds of tea one by one.

[0058] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
