Description

Technical Field

[0001] The utility model relates to the technical field of tea compacting equipment, in particular to tea compacting equipment used in tea production and processing. Background Art

[0002] Brick tea, also known as steamed and pressed tea, is tea leaves that look like bricks. It is also a representative type of compressed tea. It is made of tea leaves, tea stems, and sometimes tea powder. After the loose tea leaves are pressed into brick tea, the volume is greatly reduced, which is convenient for transportation. After the tea leaves are pressed into bricks or cakes, there is no need to worry about them breaking during transportation, which reduces the difficulty and cost of transportation. In the process of compacting tea leaves, compacting equipment is needed. The existing tea compacting equipment is mainly composed of a driving component and a single mold. The driving component drives the upper mold to move downward to compact the tea leaves inside the lower mold, thereby achieving the compaction effect.

[0003] The tea compacting equipment in the prior art has the following deficiencies during use: 1. The setting of a single mold requires personnel to take out the compacted tea leaves after completing the compaction in sequence, and then release the material for the next compaction action. The interval waiting time between the two compaction actions is relatively long, which reduces the compaction efficiency; 2. After the compaction is completed, the tea leaves in the lower mold cannot be taken out quickly, and personnel need to pick them out by hand, which is inconvenient to operate, thereby reducing the material removal efficiency and failing to meet the use requirements. Based on the above situation, we propose a tea compacting equipment for tea production and processing. Utility Model Content

The infrared signal receiver 8, the infrared signal transmitter 7 and the PLC controller 1 cooperate to automatically control the brake motor 5 to close after the two compacting frames 12 are adjusted; the utility model uses a series of structural settings to exchange the positions of the two compacting frames 12 during the compacting of tea leaves, so that the material taking and compacting operations can be carried out at the same time. When the next compacting operation is carried out, there will be no long waiting time, thereby improving the compacting efficiency, and the tea leaves after compaction can be automatically pushed out without the need for personnel to pick them out, thereby improving the material taking efficiency.

[0029] Working principle: During the compaction operation, the pressure threshold for the reverse start of the first electric telescopic rod 102 is first set through the PLC controller 1. After setting, a certain amount of tea leaves are placed in the two compaction frames 12. After placement, the first electric telescopic rod 102 is started in the forward direction. The output shaft of the first electric telescopic rod 102 drives the compaction block 2 to move downward to the compaction frame 12 on the left through the pressure sensor 4. While the compaction block 2 moves downward, it compacts the tea leaves inside the compaction frame 12. When the tea leaves are compacted to the point where they cannot move further, the compaction block 2 is restricted from moving further. At this time, the pressure sensor 4 detects the squeezing force of the first electric telescopic rod 102 and transmits the detected squeezing force to the PLC controller 1. When the pressure value reaches the threshold, The PLC controller 1 controls the first electric telescopic rod 102 to start in the reverse direction (this is the first control in the whole process). The output shaft of the first electric telescopic rod 102 drives the compacting block 2 to move out of the compacting frame 12 on the left through the pressure sensor 4. Then the compaction of the tea leaves inside the compacting frame 12 on the left is completed. When the compacting block 2 moves upward to contact the touch switch 3, the touch switch 3 is triggered to turn on. The touch switch 3 transmits the signal to the PLC controller 1 (this is the second transmission in the whole process). The PLC controller 1 controls the first electric telescopic rod 102 to close and controls the brake motor 5 to turn on in the forward direction (this is the second control in the whole process). The output shaft of the brake motor 5 drives the two compacting frames 12 to rotate through the connecting rod 6. The connecting rod 6 also drives the two The infrared signal transmitter 7 rotates. When the infrared signal transmitter 7 on the left rotates to the right and the infrared signal transmitter 7 on the right rotates to the left, the compacting frame 12 on the left rotates to the right and the compacting frame 12 on the right rotates to the left. While the compacting frame 12 rotates, it also drives the first support block 14, the first support ball, the second support block 17 and the second support ball 18 to rotate. At this time, the second support ball 18 on the right is in active contact with the top of the push block 11. At the same time, the infrared signal receiver 8 will receive the signal sent by the infrared signal transmitter 7 on the left. After receiving the signal, the infrared signal receiver 8 transmits the information to the PLC controller 1 (this is the third transmission in the whole process). At this time, the PLC controller 1 controls the brake motor 5 to close. Close and control the reciprocating electric telescopic rod 10 to open, and at the same time control the first electric telescopic rod 102 to open again to perform the compacting operation on the left side (this is the third control in the whole process). The reciprocating electric telescopic rod 10 drives the push block 11 to move up and down reciprocatingly. When the push block 11 moves upward, it squeezes the second support ball 18 in contact with it. The second support ball 18 drives the push plate 13 to move upward through the corresponding second support block 17. The push plate 13 drives the corresponding two guide rods 16 to move upward and stretch the spring 15. At the same time, the push plate 13 pushes the compacted tea leaves inside the compacting frame 12 upward, and the personnel can directly take out the compacted tea leaves without the need for digging out. The material taking efficiency is improved by automatically pushing out the material.

[0030] As the push block 11 moves downward, the squeezing force on the second supporting ball 18 is relaxed. At this time, the elastic force of the spring 15 in the stretched state drives the push plate 13 to move downward and reset, and the tea leaves to be compacted can be placed in the compacting frame 12. After placement, the tea leaves inside the compacting frame 12 on the left side complete the compacting action, and then the PLC controller 1 will control the brake motor 5 to turn on again to complete the position exchange between the two compacting frames 12. The specific process is the same as the above-mentioned operation process. By means of the interchangeable position of the two compacting frames 12, one compacting frame 12 can perform the compacting operation while the other compacting frame 12 performs the material picking and discharging work. When the next compacting operation is performed, there will be no long waiting time, thereby improving the compacting efficiency.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
