The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0020] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0021] Please see Figures 1 to 5 This utility model provides a chopsticks pre-cleaning device 200, including an oil-removing tank 201 and a scrubbing mechanism. A conveying mechanism for conveying chopsticks is installed inside the oil-removing tank 201. The conveying mechanism is provided with conveying grooves 203, and the chopsticks are located between the conveying grooves 203. The conveying mechanism is used to convey the chopsticks into the oil-removing tank 201 for soaking. The scrubbing mechanism is located behind the oil-removing tank 201, and the conveying mechanism conveys the soaked chopsticks to the scrubbing mechanism for scrubbing.

[0022] In some embodiments, the conveying mechanism may employ a conveyor chain or belt, which is provided with multiple conveying slots 203 at intervals, and the chopsticks are regularly placed in the intervals between adjacent conveying slots 203.

[0023] The pre-cleaning device 200 for chopsticks operates in two stages: a soaking stage and a scrubbing stage. First, the conveyor mechanism sends the chopsticks into the degreasing tank 201 for soaking. Then, the soaked chopsticks are conveyed forward until they enter the scrubbing mechanism located behind the degreasing tank 201.

[0024] In some embodiments, the washing mechanism specifically includes a housing 205, rollers 204, and track supports 206. Two rollers 204 are provided, each end of which is rotatably supported on the side wall of the housing 205 via bearings. The surface of the rollers 204 may be covered with cleaning materials such as bristles or sponges, and they are driven to rotate at high speed by independent drive motors. The track supports 206 are sandwiched between the two rollers 204, and have internally machined slides 207. After the chopsticks transition from the conveying mechanism to the washing mechanism, their ends rest within the slides 207 of the left and right track supports 206. At this time, the main body of the chopsticks is suspended in the area between the two rollers 204. When the rollers 204 rotate at high speed, the bristles on them thoroughly wash the middle of the chopsticks. Simultaneously, the track supports 206 not only provide support, but their slides 207 also allow the chopsticks to move slowly forward under friction during the washing process, achieving continuous automated cleaning.

[0025] In some embodiments, to ensure a smooth and unobstructed transition of chopsticks from the conveying mechanism to the washing mechanism, the side of the track support 206 near the outlet of the degreasing tank 201 is designed in a flared, funnel shape. When chopsticks are conveyed out of the degreasing tank 201 via the conveying mechanism, slight positional deviations or asynchrony may occur. The funnel-shaped inlet provides greater tolerance, guiding the chopstick tips like a funnel, allowing them to smoothly enter the slide 207 within the track support 206 even with slight positional shifts. This design significantly reduces the risk of machine stoppage due to chopsticks getting stuck at the track inlet during transfer, improving the continuity and stability of the entire washing process.

[0026] In some embodiments, the conveying mechanism is the core component that drives the chopsticks to complete the soaking and conveying process within the degreasing tank 201. The conveying mechanism mainly consists of a driving part and a transmission part. The driving part transmits power, typically a variable-speed motor. The transmission part includes a first sprocket shaft 208, a second sprocket shaft, a conveying chain 202, and sprockets 210. Two first sprocket shafts 208 and two second sprocket shafts are rotatably connected to both sides of the inner wall of the degreasing tank 201 via bearing seats and other supporting components. Along the height direction of the degreasing tank 201, the two first sprocket shafts 208 are located above, and the two second sprocket shafts are located below, thus forming a three-dimensional transmission loop. Each shaft is equipped with two sprockets 210. The two conveying chains 202 mesh with the corresponding upper and lower sprockets 210, thus forming a closed circular transmission path. The transmission power is connected to one of the shafts via the conveying chain 202, a belt, or a reducer, driving its rotation and thus driving the entire conveying chain 202 to circulate. The chopsticks fixed on the conveyor chain 202 move with the conveyor chain 202, sequentially completing the cycle of descending, horizontal immersion, rising, and returning.

[0027] In some embodiments, to ensure stable operation of the conveyor chain 202 and prevent it from loosening and jumping, a clamping mechanism is also provided inside the degreasing tank 201. The clamping mechanism includes a rotating shaft 211 and one or more pressure rollers 212 mounted on the first rotating shaft 211. The rotating shaft 211 is typically rotatably connected to the inner wall of the degreasing tank 201 via a bearing housing, and its installation position is located above the conveyor chain 202 loop or near a specific bending point. The outer circumferential surface of the pressure roller 212 is in direct contact with the conveyor chain 202. It uses its own weight or applies a downward pressure through an adjustable mechanism to continuously press the slack side of the conveyor chain 202 towards the bottom of the degreasing tank 201. This effectively eliminates the sag of the conveyor chain 202 caused by stretching during long-term operation, preventing the conveyor chain 202 from jumping, slapping, or mis-engaging with the sprocket 210 during operation, thus ensuring the smoothness and reliability of power transmission.

[0028] In some embodiments, to prevent chopsticks from slipping off the conveyor chain 202 during transport, and especially to prevent them from getting stuck or damaged in the narrow gap between the conveyor chain 202 and the inner wall of the degreasing tank 201, a first baffle 213 is provided between the conveyor chain 202 and the inner wall of the degreasing tank 201. This first baffle 213 is typically a long, strip-shaped structure, with its length parallel to the running path of the conveyor chain 202, and is fixed to the inner wall of the degreasing tank 201. The first baffle 213 provides lateral obstruction and limitation for the chopsticks, ensuring that they maintain the correct posture throughout the soaking and transport process, and will not deviate from their predetermined position due to water flow impact, equipment vibration, or centrifugal force when the chain turns, thereby ensuring the orderliness and reliability of the entire cleaning process.

[0029] In some embodiments, a second baffle 214 is provided on the side of the conveyor chain 202 away from the first baffle 213, and the second baffle 214 is connected to the inner wall of the degreasing tank 201 through a connector 215.

[0030] In addition to the first baffle 213 already installed on the side of the conveyor chain 202 near the inner wall of the degreasing tank 201, a second baffle 214 is also installed on the other side of the conveyor chain 202 away from the first baffle 213. The second baffle 214 is securely connected to the inner wall of the degreasing tank 201 or other supporting structure via a connector 215. The connector 215 can be a bracket, bolt, etc. The first baffle 213 and the second baffle 214 are located on opposite sides of the conveyor chain 202, thereby limiting the pressure roller 212 and preventing it from moving left or right.

[0031] In some embodiments, to significantly improve the initial cleaning effect of the degreasing tank 201 on chopsticks, especially to remove stubborn stains and particles in crevices, the degreasing tank 201 is provided with a plurality of ultrasonic vibrators 216, which are evenly distributed on the bottom or side wall of the housing.

[0032] In some embodiments, the ultrasonic vibrator 216 is a piezoelectric ceramic transducer. When a high-frequency electrical signal is applied, the ultrasonic vibrator 216 converts electrical energy into high-frequency mechanical vibration, generating a dense ultrasonic cavitation effect in the cleaning fluid. Specifically, countless tiny bubbles in the liquid rapidly form and violently burst, generating strong localized shock waves and micro-jet streams at the moment of bursting. This powerful physical force can act on every corner of the chopsticks' surface, effectively removing adhering oil and other contaminants. Its cleaning effect far surpasses simple soaking, laying a solid foundation for subsequent scrubbing processes and achieving deep cleaning.

[0033] In some embodiments, to facilitate the maintenance, cleaning, and separation and discharge of different contaminants in the degreasing tank 201, a differentiated drainage system is provided on the degreasing tank 201. Specifically, a first drain hole 217 is provided on the side wall of the degreasing tank 201, while a second drain hole 218 is provided at the bottom of the degreasing tank 201. This design fully considers the effective removal of contaminants of different densities. Since the grease generated during the cleaning process has a density less than water, it will float on the water surface. Therefore, an important function of the higher-positioned first drain hole 217 is as a drain hole for floating oil (and surface wastewater). When emptying the degreasing tank 201, the grease-rich surface liquid can be discharged first through the first drain hole 217 to achieve preliminary separation of oil and grease. Subsequently, the second drain hole 218 located at the bottom of the tank is opened. Since solid particles such as food residue have a density greater than water, they will settle at the bottom of the tank. The second drain hole 218 is used to completely empty the bottom wastewater and remove the deposited solid impurities. This combined high and low-level drainage design allows for more scientific and efficient treatment of different types of cleaning waste, facilitating wastewater classification and tank cleaning. Simultaneously, the first drain hole 217 can also function as an overflow hole, maintaining a stable liquid level within the tank during normal cleaning processes and preventing excessively high water levels.

[0034] In some embodiments, a liquid level sensor is installed in the degreasing tank 201. Multiple liquid level sensors can be set in the degreasing tank 201. When the liquid level is lower than the set lower limit, the system automatically opens the water inlet valve until the liquid level reaches the set upper limit and then closes it to ensure that there is sufficient liquid during the cleaning process.

[0035] In some embodiments, a heater 219 is also provided in the degreasing tank 201 to heat the water in the degreasing tank 201, resulting in better decontamination. The liquid level sensor can cut off the power to the heater 219 when the liquid level is too low to prevent dry burning and potential safety accidents.

[0036] In some embodiments, to ensure that chopsticks can be smoothly and orderly transferred from the conveying mechanism of the degreasing tank 201 to the washing mechanism at the rear end, and to prevent jamming or falling at the interface, a guide plate 209 is provided on the side of the degreasing tank 201 near the washing mechanism. This guide plate 209 is typically a smooth plate-like structure, with one end adjacent to the discharge end of the conveyor chain 202, and the other end extending above or in front of the washing mechanism (such as the flared inlet of the track bracket 206). The guide plate 209 mainly receives and guides the chopsticks. When the chopsticks are sent out of the degreasing tank 201 by the conveyor chain 202, the guide plate 209 provides a smooth transition slope or channel, constraining the movement trajectory of the chopsticks so that, under the action of gravity or inertia, they slide or fall smoothly and controllably into the designated receiving position of the washing mechanism (such as the slide rail 207 of the track bracket 206), thereby achieving a reliable connection between the two main workstations and ensuring the smoothness of continuous production.

[0037] This utility model also provides an automatic chopsticks cleaning device, including the aforementioned chopsticks pre-cleaning device and a chopsticks feeding device installed at the front end of the chopsticks pre-cleaning device. The chopsticks feeding device arranges the chopsticks so that they enter the chopsticks pre-cleaning device 200 one by one. A rinsing device is also installed at the rear end of the washing mechanism to rinse the chopsticks.

[0038] The operator places the chopsticks to be cleaned onto the conveyor mechanism at the feed end of the degreasing tank 201. The chopsticks are neatly positioned between the conveyor grooves 203 of the conveyor chain 202. The conveyor chain 202 starts, carrying the chopsticks slowly into and completely immersing them in the cleaning solution in the degreasing tank 201. During this process, the cleaning solution initially softens the stains adhering to the chopsticks. Simultaneously, multiple ultrasonic vibrators 216 installed inside the degreasing tank 201 begin to operate, generating a powerful cavitation effect. The impact force of the bursting microbubbles violently impacts the surface of the chopsticks from all angles, efficiently removing stubborn oil and particles.

[0039] After soaking and ultrasonic cleaning, the conveyor chain 202 transports the chopsticks to the end of the degreasing tank 201. The guide plate 209 located at the outlet of the degreasing tank 201 smoothly receives and guides the chopsticks, allowing them to slide into the subsequent brushing mechanism, effectively preventing jamming or falling at the interface.

[0040] The chopsticks fall into the slides 207 of the two track supports 206 of the washing mechanism at both ends, with the middle section of the chopsticks suspended in the air. Two high-speed rotating rollers 204 vigorously scrub the main body of the chopsticks. Under the action of friction, the chopsticks move slowly forward along the slides 207. After deep scrubbing, the clean and dry chopsticks are discharged from the end of the washing mechanism and then rinsed by the rinsing device, completing the entire cleaning process.

[0041] Throughout the cleaning process, the liquid level sensor in the degreasing tank 201 monitors the liquid level in real time and automatically controls the opening and closing of the water inlet valve to maintain a constant cleaning liquid level. After cleaning, grease with a density less than water can be preferentially discharged through the first drain hole 217 on the higher side wall, while solid residues settled at the bottom of the tank are completely discharged through the second drain hole 218 at the bottom, achieving classified cleaning of dirt. The chopsticks pre-cleaning device 200 provided by this utility model combines ultrasonic soaking with mechanical brushing, and utilizes automatic conveying, liquid level control, intelligent sewage discharge, and guided transition design to form a highly efficient, thorough, and fully automated chopsticks cleaning production line.

[0042] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
