Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly tableware processing technology, specifically to a raw material cleaning device for environmentally friendly tableware processing. Background Technology

[0002] Eco-friendly tableware, as a biodegradable alternative, primarily utilizes plant fibers (such as straw, bagasse, and bamboo fiber) as processing raw materials. Cleaning is a crucial step in the processing of these raw materials, aiming to remove mud, dust, and other impurities adhering to the surface, ensuring the hygiene and quality of the final tableware product.

[0003] Bubble washing machines are widely used for cleaning plant fiber raw materials. Their working principle typically involves an aeration device at the bottom of the machine generating a large number of bubbles. As these bubbles rise, they tumble and wash the raw material, and combined with the water flow, achieve initial cleaning. However, relying solely on bottom-based bubbles has limited effectiveness in removing firmly attached impurities or those embedded in the crevices of the raw material. Therefore, existing technologies have developed improvements by adding a high-pressure rinsing device to the top of the bubble washing machine. This uses high-pressure water to further rinse floating or suspended materials, aiming to improve overall cleanliness.

[0004] However, these existing high-pressure rinsing devices are usually fixed in place, and the spray angle of their nozzles is not adjustable. This results in dead zones in the rinsing coverage area, making it impossible to dynamically adjust the rinsing according to the distribution and flow of the raw materials in the cleaning tank. Consequently, the rinsing uniformity is poor, hindering further improvements in cleaning efficiency and effectiveness.

[0005] Therefore, we propose an environmentally friendly tableware processing raw material cleaning device. Utility Model Content

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides an environmentally friendly tableware processing raw material cleaning device, which has the following beneficial effects: 1.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: an environmentally friendly tableware processing raw material cleaning device.

[0022] Specifically, it includes a bubble washer 1 and a high-pressure rinsing structure 2. The bubble washer 1 is used to initially tumble and clean the plant fiber raw materials (such as straw, bagasse, etc.) in the tank by using bubbles generated at the bottom. The high-pressure rinsing structure 2 is fixedly installed on the upper part of the bubble washer 1 and is used to dynamically and high-pressure supplement rinse the raw materials floating or suspended in the tank of the bubble washer 1.

[0023] The high-pressure rinsing structure 2 includes a motor mounting base 3, a drive motor 4, and six sets of high-pressure rinsing units 5. The motor mounting base 3 is fixed to one end of the upper outer surface of one side of the bubble cleaner 1 by welding. The drive motor 4 (preferably a servo motor with forward and reverse control function or a regular motor with control circuit) is fixedly mounted on the upper outer surface of the motor mounting base 3.

[0024] The high-pressure rinsing unit 5 includes a transmission box 6, a drive shaft 7, a water guide pipe 8, a support frame 9, a high-pressure nozzle 10, an interface 11, a worm gear 12, a worm 13, and a filter screen 14. The transmission box 6 is fixed to the upper part of the outer surface of one side of the bubble cleaner 1. Along the length of the bubble cleaner 1, the transmission boxes 6 of the six high-pressure rinsing units 5 are arranged in sequence.

[0025] The output shaft of the drive motor 4 is connected to the drive shaft 7 of the nearest high-pressure flushing unit 5 via a coupling. Multiple drive shafts 7 are also connected sequentially via couplings, thereby enabling all six high-pressure flushing units 5 to be driven synchronously by one drive motor 4.

[0026] In a high-pressure rinsing unit 5, the drive shaft 7 runs through the lower part of the entire transmission box 6. Two sets of support frames 9 are symmetrically fixed on the left and right sides of the upper outer surface of the bubble cleaner 1. A water guide pipe 8 connects between these two sets of support frames 9, with its axis approximately parallel to the width direction of the bubble cleaner 1. One end of the water guide pipe 8 passes through and extends to the upper part of the transmission box 6. An interface 11 is provided on the outer surface of this end of the water guide pipe 8 for connection to an external high-pressure water supply line via a rotary joint (not shown in the figure), ensuring uninterrupted water supply when the water guide pipe 8 rotates.

[0027] Multiple high-pressure nozzles 10 are evenly spaced and installed on one side of the outer surface of the water guide pipe 8 for spraying high-pressure water jets. Both the worm gear 13 and the worm wheel 12 are housed inside the transmission housing 6. The worm gear 13 is fixedly sleeved on the outer wall of the middle portion of the drive shaft 7. The worm wheel 12 is fixedly sleeved on the outer wall of the portion of the water guide pipe 8 located inside the transmission housing 6, and is positioned above the worm gear 13, so that the worm gear 13 and the worm wheel 12 mesh with each other, forming a worm gear transmission pair.

[0028] To achieve a self-locking function and prevent the water flow reaction force from causing the guide pipe 8 to rotate on its own, the worm gear 13 is designed as a single-start worm gear, and its lead angle is smaller than the equivalent friction angle of the worm wheel pair. This gives the transmission a reverse self-locking characteristic; the guide pipe 8 will only rotate when the drive motor 4 actively drives it.

[0029] The filter screen 14 is fixed inside the water pipe 8 and located at the end near the interface 11. Its function is to filter the flushing water from the external water supply system, intercept large particulate impurities in the water, and prevent the high-pressure nozzle 10 from clogging.

[0030] A first sealed bearing is provided at the penetration point between the drive shaft 7 and the transmission box 6, through which the drive shaft 7 is rotatably connected to the transmission box 6. Similarly, sealed bearings are provided at the penetration point between the water guide pipe 8 and the transmission box 6, as well as at the connection point between the water guide pipe 8 and the two side support frames 9, through which the water guide pipe 8 is rotatably connected to the transmission box 6 and the support frames 9.

[0031] Working principle: When using this invention, first start the bubble cleaner 1 and the external high-pressure water supply system. High-pressure water enters the water guide pipe 8 through interface 11, is filtered by the built-in filter screen 14, and is then sprayed downwards into the cleaning tank of the bubble cleaner 1 by the equidistantly arranged high-pressure nozzles 10. At the same time, start the drive motor 4. The drive motor 4 drives all drive shafts 7 to rotate synchronously through a coupling. The drive shafts 7 drive the worm gear 13 on them to rotate, the worm gear 13 drives the worm wheel 12 meshing with it to rotate, and the worm wheel 12 drives the water guide pipe 8 and all the high-pressure nozzles 10 on it to slowly and periodically rotate (oscillate) around the axis of the water guide pipe 8.

[0032] The oscillation of the high-pressure nozzle 10 expands the water flow coverage, enabling multi-angle, comprehensive dynamic rinsing of materials tumbling within air bubbles, thus improving cleaning effectiveness, especially beneficial for removing stubborn impurities from fiber gaps. The self-locking characteristic of the worm gear pair ensures the nozzle remains stable at any angle, preventing displacement due to water flow impact. The built-in filter 14 continuously filters the water supply, ensuring long-term stable operation of the high-pressure nozzle 10 and reducing maintenance requirements.
