[0026] Conveyor line 60. Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0028] Reference Figures 1 to 4 The semi-automatic washing line shown is used to clean tableware placed in washing frames. It includes an air bubble rinsing tank 10, an ultrasonic soaking cleaning tank 20, a spray washing device 30, a drying device 40, a hoisting and conveying device 50, and a conveyor line 60. The air bubble rinsing tank 10 is used to initially remove oil stains from the surface of the tableware. The ultrasonic soaking cleaning tank 20 is used to deeply clean stains in crevices. The spray washing device 30 is used to rinse off residual detergent. The drying device 40 is used to dry the tableware. The hoisting and conveying device 50 hoists the washing frames and transfers them between the air bubble rinsing tank 10 and the ultrasonic soaking cleaning tank 20. The conveyor line 60 can receive the washing frames output by the hoisting and conveying device 50 and is used to transport the washing frames to the spray washing device 30 and the drying device 40.

[0029] Specifically, the washing frame is a stainless steel mesh frame that can accommodate multiple sets of tableware, with reinforcing ribs at the bottom to prevent deformation; the hoisting and transporting device 50 can use a gantry-type hoist, and the conveyor line 60 is a mesh chain conveyor belt. All equipment is arranged sequentially in a straight line, minimizing floor space. This washing line achieves semi-automation of tableware washing through modular combination and automated transfer, balancing efficiency and cost, and is suitable for small to medium-sized venues.

[0030] See Figure 1 and Figure 3 In this application, the bubble rinsing tank 10 is a stainless steel water tank with multiple bubble generators 11 evenly installed at the bottom. The high-pressure bubbles generated by the bubble generators 11 rise from the bottom of the tank, impacting the surface of the tableware, removing oil and food residue, resulting in high initial cleaning efficiency and avoiding scratches to the tableware due to the absence of mechanical friction. At the same time, the water inside the bubble rinsing tank 10 contains detergent, which helps to improve the cleaning effect.

[0031] In addition, in one embodiment of this application, the ultrasonic soaking cleaning tank 20 is the same size as the bubble rinsing tank 10. The ultrasonic soaking cleaning tank 20 is equipped with multiple sets of ultrasonic generators 21, which are distributed on the tank wall and the bottom of the tank. The ultrasonic waves generated by the ultrasonic generators 21 can penetrate the gaps of tableware and shake off the stubborn stains attached to them. It is especially suitable for hard-to-clean areas such as the edges of bowls and plates and the gaps between chopsticks. The ultrasonic soaking time can be set by the background control system to adapt to tableware with different levels of stains.

[0032] It should be noted that in this application, both the bubble rinsing tank 10 and the ultrasonic soaking cleaning tank 20 are equipped with slag discharge ports at the bottom, and control valves are installed on the slag discharge ports to periodically open and discharge the sediment at the bottom; a water inlet is provided at the top, which is connected to tap water or hot water pipes, and detergent or hot water can be added as needed to improve the oil stain dissolution efficiency; a liquid level sensor is installed on the tank wall to automatically replenish water when the water level is too low.

[0033] See Figure 1 and Figure 2 In this application, for the sake of simplified design and reduced equipment costs, the hoisting and conveying device 50 includes a frame 51, a horizontal rail 52 mounted on the frame 51, and a self-propelled platform 53 capable of moving along the horizontal rail 52. The self-propelled platform 53 is equipped with a lifting device 54 capable of lifting and lowering. The lifting device 54 can grasp the cleaning frame. The horizontal rail 52 spans above the bubble rinsing tank 10 and the ultrasonic immersion cleaning tank 20, with both ends extending outwards. One end of the horizontal rail 52 is located above the feeding end of the conveyor line 60, which can receive the cleaning frame below the lifting device 54. The frame 51 is a welded square steel structure fixed to the ground; the horizontal rail 52 is an I-beam; the lifting device 54 is a hook structure or a mechanical gripper structure, adapted to the hanging lugs on both sides of the cleaning frame.

[0034] To facilitate self-propelled operation, a rack 55 is provided on the frame 51, parallel to the horizontal rail 52. A travel motor 56 is provided on the self-propelled platform 53, and a gear 57 that meshes with the rack 55 is provided on the output end of the travel motor 56. Simultaneously, to enable the lifting action of the lifting device 54, a lifting device 58 is provided on the self-propelled platform 53. The lifting device 54 is installed at the lower end of the lifting device 58 and can grab or release the cleaning frame. In the above embodiment, both the travel motor 56 and the lifting device 58 are connected to the central control system and can be controlled by buttons or foot switches, making operation convenient.

[0035] See Figure 1 and Figure 4 The spray washing device 30 includes a support frame 31, a protective cover 32 mounted on the support frame 31, and several nozzles 33 disposed within the protective cover 32. The conveyor line 60 passes through the protective cover 32. A collection cover 34 is disposed on the support frame 31 below the conveyor line 60. A water outlet is disposed at the bottom of the collection cover 34, and a filter box 35 is disposed on the water outlet. A collection box 36 is disposed on the support frame 31 below the water outlet. A purifier 37 and a water supply pump 38 are disposed inside the collection box 36. The inlet end of the water supply pump 38 is connected to the purifier 37, and the outlet end of the water supply pump 38 is connected to the nozzles 33 through a pipeline. The protective cover 32 can be made of transparent acrylic material or can be equipped with an observation window to prevent splashing of washing water. The nozzles 33 are arranged in a ring around the periphery of the conveyor line 60, and multiple nozzles are also disposed on the sides, mainly for rinsing from the side. The collection hood 34 is funnel-shaped and made of stainless steel. It collects the rinsing water and introduces it into the filter box 35 through the outlet. The filter box 35 is equipped with multiple layers of filter screens. The purifier 37 in the collection box 36 sterilizes and softens the water after rinsing. The water supply pump 38 delivers the treated water to the nozzle 33 through the pipeline to realize water recycling.

[0036] See Figure 1 and Figure 4 The drying device 40 includes a frame 41, a drying hood 42, and a hot air blower 43. The frame 41 is a stainless steel frame, and the drying hood 42 is mounted on the frame 41. The conveyor line 60 runs through the drying hood 42. The hot air blower 43 is installed at the bottom of the drying hood 42 with its air outlet facing upwards. The hot air generated forms an airflow inside the drying hood 42, carrying away moisture from the surface of the tableware. An exhaust vent is provided at the top of the drying hood 42 to expel humid air and prevent water vapor condensation and backflow. The drying time can be adjusted by the speed of the conveyor line 60 to ensure that the moisture content of the tableware is at a low level after drying. An observation window is provided on the side of the drying hood 42 to monitor the drying process in real time.
