Description

Technical Field

[0001] This utility model relates to the field of tea packaging machines, and in particular to a vacuum compression tea packaging machine. Background Technology

[0002] A tea packaging machine is a type of mechanical equipment specifically designed for tea packaging. It can efficiently and accurately complete processes such as weighing, packaging, and sealing of tea.

[0003] In traditional vacuum compression tea packaging machines, if the bag opening is not fully or stably kept open when the packaging bag is opened, the tea can easily overflow from the bag opening during the filling process. This not only wastes valuable raw materials but may also pollute the production environment, increase cleaning and maintenance costs, and the unstable bag opening may lead to insufficient tea filling, affecting the integrity of the packaging and the standardization of the product, thereby reducing customer satisfaction.

[0004] To address the aforementioned issues, a vacuum compression tea packaging machine capable of controlling the opening of the packaging bag needs to be designed. Utility Model Content

[0022] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0023] Example: A vacuum compression tea packaging machine, such as Figures 1-8As shown, the machine includes a base 1, a rotating frame 2, rotating rods 3, a feeding frame 4, a torsion spring 5, a motor 6, a discharge frame 7, a support frame 71, a baffle plate 72, a packaging machine body 8, a mounting frame 81, an air extraction pipe 9, an air pump 10, a guide rod 11, a sliding frame 12, a first guide rod 13, a screw 14, a bidirectional motor 15, a bag mouth support block 16, a cylinder 17, a second guide rod 18, a squeezing frame 19, an electric push rod 20, a protrusion 21, and a receiving frame 22. A motor 6 is installed inside the base 1. The rotating frame 2 is connected to the output shaft of the motor 6. Several rotating rods 3 are rotatably connected to the rotating frame 2. Each rotating rod 3 has a feeding frame 4 connected to its center for feeding. Frame 4 is used to place packaging bags. Two torsion springs 5 ​​connect the feeding frame 4 and the rotating frame 2. A support frame 71 is connected to the right side of the base 1. A feeding frame 7 is connected to the left side of the support frame 71. The feeding frame 7 is used to place tea leaves and discharge them. A baffle plate 72 is rotatably connected to the lower part of the feeding frame 7. The baffle plate 72 passes through the feeding frame 7. The size of the baffle plate 72 is adapted to the baffle opening at the lower part of the feeding frame 7. The baffle plate 72 is used to control the flow rate and volume of the tea leaves to prevent them from overflowing or falling to the ground. A mounting frame 81 is connected to the left side of the base 1. The packaging machine body 8 is mounted on the upper part of the mounting frame 81. The packaging machine body 8 is used to handle the tea leaves. The packaging bags for the leaves are heat-sealed. An air pump 10 is installed on the left side of the packaging machine body 8, and an air extraction pipe 9 is connected to the left side of the air pump 10. A cylinder 17 is installed on the upper right side of the support frame 71, and a sliding frame 12 is connected to the lower end of the telescopic rod of the cylinder 17. Guide rods 11 are symmetrically connected to the front and rear of the outer wall of the feeding frame 7. The sliding frame 12 is slidably connected to the guide rods 11. First guide rods 13 are symmetrically connected to the left and right sides of the lower front side of the sliding frame 12. A bidirectional motor 15 is installed on the lower rear side of the sliding frame 12. Screws 14 are connected to the output shafts at both ends of the bidirectional motor 15. Bag opening support blocks 16 are slidably connected to both screws 14. The bag opening support blocks 16 are used to support and adjust the packaging bags. The bag opening size is determined by two bag opening support blocks 16 and two first guide rods 13, which are slidably connected. The space formed between the two bag opening support blocks 16 is tightly fitted with the discharge port of the feeding frame 7. A second guide rod 18 is connected to the base 1, and an electric push rod 20 is installed on the front side of the base 1. An extrusion frame 19 is connected to the upper end of the electric push rod 20. The extrusion frame 19 is slidably connected to the second guide rod 18. Both ends of the rotating rod 3 are connected to protrusions 21. The extrusion frame 19 and the protrusions 21 are in contact and cooperate. The contact point between the extrusion frame 19 and the protrusions 21 is designed in a U-shape. A receiving rack 22 is connected to the front side of the base 1. The receiving rack 22 is used to collect the finished packaging bags.

[0024] When this device is needed for vacuum packaging of tea, the operator first connects the vacuum pump to the suction pipe 9. After the vacuum pump is connected, the operator starts the packaging machine to put it into operation. Then, the operator places the packaging bags into the feeding frame 4 one by one. After the packaging bags are placed, the operator pours the tea into the unloading frame 7. When a certain amount of tea has been poured, the operator starts the motor 6. The output shaft of the motor 6 drives the rotating frame 2 to rotate counterclockwise. During the rotation of the rotating frame 2, all the components on it rotate. When the feeding frame 4 containing the packaging bags rotates to below the unloading frame 7, the operator starts the cylinder 17. The telescopic rod of the cylinder 17 drives the sliding frame 12 and all the components on it to move downwards along the guide rod 11. When the bag opening support block 16 moves into the inlet of the packaging bag, the operator starts the bidirectional motor 15. The output shafts at both ends of the bidirectional motor 15 drive the screw 14 to rotate. The screw 14 drives the two bag opening support blocks 16 to move outward along the first guide rod 13. The movement of the two bag opening support blocks 16 opens the inlet of the packaging bag. When the inlet of the packaging bag is opened to an appropriate size, the bidirectional motor 15 is turned off. Then the operator rotates the baffle plate 72 until it is rotated to a suitable angle. The tea leaves fall smoothly into the opened packaging bag through the outlet of the feeding frame 7. When the tea leaves are filled to the predetermined amount, the operator rotates the baffle plate 72 in the opposite direction until it returns to its original position. Then the operator releases the baffle plate 72 and starts the process again. The bidirectional motor 15 rotates in reverse, driving the screw 14 to rotate in the opposite direction. The screw 14 moves the two bag opening support blocks 16 inward along the first guide rod 13 until they are in contact with the discharge port of the feeding frame 7. Then, the bidirectional motor 15 is turned off. Subsequently, the cylinder 17 drives the sliding frame 12 and all its components to move upward along the guide rod 11 until they reach their initial position. Then, the cylinder 17 is turned off. The rotating frame 2 continues to drive the feeding frame 4, the tea-filled packaging bag, and all its components to rotate. When the feeding frame 4 rotates to the side of the packaging machine, the operator uses a flat plate to fold the opening of the tea-filled packaging bag into the packaging machine. After the opening of the tea bag is inside the packaging machine, the flat plate is retracted. At this time, the cover of the packaging machine automatically closes to clamp the opening of the tea bag. Then, the air pump 10 is started, and the air inside the tea bag is drawn into the vacuum extractor through the air extraction pipe 9. After all the air inside the tea bag has been extracted, the air pump 10 is turned off. At this time, the packaging machine heat-seals the opening of the tea bag to ensure that the packaging bag is completely sealed and leak-free. After the packaging bag is sealed, the cover of the packaging machine automatically opens. Then, the rotating frame 2 drives the feeding frame 4, the sealed packaging bag, and all its components to continue rotating. When the feeding frame 4 rotates to the position of the receiving frame 22, the operator starts the electric push rod 20.The electric push rod 20 drives the extrusion frame 19 to move upward along the second guide rod 18. The extrusion frame 19 moves and contacts the protrusion 21, applying pressure to it. This causes the protrusion 21 to drive the rotating rod 3 and the feeding frame 4 to rotate, deforming the torsion spring 5. When the feeding frame 4 rotates to fit against the receiving frame 22, the sealed packaging bag slides onto the receiving frame 22, facilitating collection by staff. Then, the electric push rod 20 drives the extrusion frame 19 downward along the second guide rod 18 until it reaches its initial position, at which point the motor is turned off. During this process, the protrusion 21 is no longer under pressure. Under the reset action of the torsion spring 5, the rotating rod 3 drives the feeding frame 4 and the protrusion 21 to rotate in the opposite direction until the feeding frame 4 returns to its original position. When the next feeding frame 4 containing a packaging bag rotates to below the feeding frame 7, all the above operations are repeated. After all the tea leaves are vacuum-packed, the motor 6, the packaging machine, and the vacuum pump are turned off in sequence.
