Description

Technical Field

[0001] This utility model relates to the technical field of dust prevention devices, specifically a dust prevention device for tea packaging equipment. Background Technology

[0002] Dust pollution is easily generated during the tea production process, particularly in the packaging stage. On the one hand, fine tea dust is generated due to friction and breakage during the conveying, unloading, and weighing of tea leaves; on the other hand, dust suspended in the workshop environment may fall into the tea leaves, affecting their hygiene, quality, and taste.

[0003] Current traditional tea packaging equipment mostly uses enclosed enclosures for simple protection, but lacks an effective internal dust removal mechanism, leading to dust accumulation. In addition, the lack of a preliminary screening function for tea leaves during the feeding process makes it easy for impurities or clumps of tea leaves to enter the packaging stage, reducing product quality. Therefore, we have proposed a dust prevention device for tea packaging equipment. Utility Model Content

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Example: Figures 1-6 As shown, the dustproof device of the tea packaging equipment of this utility model includes a packaging box 1, a filter box 2 fixedly connected to one side of the packaging box 1, a feed pipe 3 fixedly connected to the top of the packaging box 1, a lifting frame 4 movably connected inside the packaging box 1, a vacuum cleaner 6 fixedly installed on one side of the packaging box 1 through a connecting plate 5, a dust suction hood 7 fixedly connected to the output end of the vacuum cleaner 6, and one end of the dust suction hood 7 communicating with the filter box 2, a filter screen 8 slidably connected inside the filter box 2, and a dust suction plate 9 fixedly connected to the inner wall of one side of the packaging box 1, and the dust suction plate 9 communicating with the filter box 2.

[0026] The gap between the filter screen 8 and the dust collection plate 9 is provided with a conveying pipe 10, and one end of the conveying pipe 10 passes through the filter box 2 and is connected to one side of the feed pipe 3. When the vacuum cleaner 6 is started, the conveying pipe 10 generates negative pressure inside the feed pipe 3, and the dust generated by the tea leaves is captured in real time during the feeding process, so as to achieve "dust control at the source", prevent dust from overflowing the equipment, and achieve effective dust prevention.

[0027] Among them, a servo motor 11 is fixedly installed on the outer periphery of the packaging box 1. The output end of the servo motor 11 is connected to a rotating shaft 12. A cam 13 is fixedly connected to the outer periphery of the center end of the rotating shaft 12. The outer periphery of the cam 13 abuts against the bottom of the lifting frame 4. The cam 13 is fixed to the middle of the rotating shaft 12. Its outline is an eccentric circle. When rotating, it periodically pushes the bottom of the lifting frame 4 to realize reciprocating lifting motion.

[0028] The lifting frame 4 has a limit plate 14 fixedly connected to both sides, and the inner sides of the packaging box 1 have limit grooves 15, and the interior of the two limit grooves 15 is slidably connected to the two limit plates 14.

[0029] Each of the two limiting grooves 15 has two fixedly connected sliding pillars 16 inside, and the four sliding pillars 16 are slidably connected to the two limiting plates 14. Each of the four sliding pillars 16 has a return spring 17 sleeved on its outer periphery. The two ends of the return spring 17 are fixed to the top of the limiting plate 14 and the top wall of the limiting groove 15, respectively. Through through holes in the limiting plate 14, the return spring 17 slides with the sliding pillars 16, ensuring no swaying during the lifting process. The return spring 17 is sleeved on the outer periphery of the sliding pillars 16, with one end pressing against the upper surface of the limiting plate 14 and the other end abutting against the inner top wall of the limiting groove 15, providing a rebound force so that the lifting frame 4 quickly returns to its original position after the cam disengages from contact, improving vibration efficiency.

[0030] The top of the lifting frame 4 is detachably connected to a filter frame 18. Both the lower surfaces of the lifting frame 4 and the filter frame 18 are provided with several material leakage holes 19. Both sides of the filter frame 18 are fixedly connected to handles 20. The detachable filter frame 18 is provided above the lifting frame 4, and its size matches the lifting frame 4, making it easy to install and remove.

[0031] The inner wall of the dispensing box 1 is fixedly connected to a stirring funnel 21, and a geared motor 22 is fixedly installed at the bottom of the stirring funnel 21. The output end of the geared motor 22 is connected to a stirring shaft 23, and several stirring rods 24 are fixedly welded to the outer periphery of the stirring shaft 23. A collection box 25 is slidably connected to the bottom of the dispensing box 1. A box door 26 is provided on the side near the lifting frame 4, and the box door 26 is rotatably connected to the dispensing box 1. By using the stirring shaft and stirring rods driven by the geared motor inside the stirring funnel, the tea leaves can be stirred and dispersed at the initial stage of entering the dispensing box. The dust and other dust remaining on the surface of the tea leaves can be captured in real time by the dust collection plate, reducing the concentration of suspended particulate matter in the air inside the dispensing equipment, effectively removing dust, preventing dust from overflowing from the equipment, and achieving effective dust prevention.

[0032] Working Principle: During operation, the vacuum cleaner 6 is activated. Through the cooperation of the vacuum hood 7 and the conveying pipe 10, a negative pressure airflow is generated inside the feed pipe 3. Tea leaves are then fed into the packaging box 1 through the feed pipe 3. Fine dust generated during the tea leaf entry process is quickly captured and sucked into the filter box 2 along the conveying pipe 10, then falls into the stirring funnel 21. At this time, the reduction motor 22 is activated, driving the stirring shaft 23 and the stirring rod 24 welded to its outer circumference to rotate, uniformly stirring and dispersing the tea leaves. The tea leaves then fall through the aperture on the surface of the stirring funnel 21 into the filter frame 18. Simultaneously, the servo motor 11 is activated, driving the rotating shaft 12 to continuously rotate the cam 13. The cam 13 periodically pushes the bottom of the lifting frame 4, causing it to reciprocate up and down along the limiting groove 15. During the upward movement, the return spring 17 is compressed; after the cam 13 reaches its highest point, the lifting frame 4 falls back under its own weight and the elastic force of the return spring 17, creating a stable vibrating screening effect. Under this vibration, the tea leaves continuously bounce within the filter frame 18. Fine tea dust and impurities fall through the discharge hole 19 into the lower part of the lifting frame 4, while whole tea leaves remain within the filter frame 18, achieving preliminary sieving and purification. Simultaneously, the vacuum cleaner 6 creates a negative pressure airflow inside the packaging box 1 through the dust suction hood 7 and dust suction plate 9, drawing the dust generated during the stirring and vibration of the tea leaves into the filter box 2. The dust is effectively intercepted by the sliding filter screen 8, and clean air is discharged through the vacuum cleaner 6, preventing dust from overflowing and polluting the environment or flowing back into the tea leaves, thus preventing dust from overflowing from the equipment and achieving effective dust prevention. After the equipment has been running for a period of time, the box door 26 can be rotated and opened, and the filter frame 18 can be pulled out through the handle 20 to clean the residual impurities inside. At the same time, the filter screen 8 can also be slid out of the filter box 2 to remove accumulated dust.
