[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific examples described herein are merely illustrative and not intended to limit the scope of the invention.

[0019] Please see Figures 1-3 As shown, an integrated pre-treatment equipment for vegetable washing and packaging includes a washing device and a packaging device arranged in front and behind, which respectively wash and package the vegetables.

[0020] The cleaning device includes a wastewater tank 1, a first belt conveyor 2, and a cleaning mechanism, wherein: The top opening of sewage tank 1; The first belt conveyor 2 has several partitions 3 on its conveyor belt, and a vegetable placement trough is formed between two adjacent partitions 3.

[0021] Specifically, the water supply system includes a water source pump 6 and a three-way water distribution valve 7. The water source pump 6 is connected to the first interface of the three-way water distribution valve 7 through a pipeline. The second and third interfaces of the three-way water distribution valve 7 are both connected to the cleaning pipe 4 through pipelines. A booster pump 8 and a first shut-off valve 9 are connected between the second interface of the three-way water distribution valve 7 and the cleaning pipe 4. A vegetable cleaner additive 11 and a second shut-off valve 10 are provided between the third interface of the three-way water distribution valve 7 and the cleaning pipe 4.

[0022] In this embodiment, for example, a feeding chute 18 is provided on the sewage tank 1 corresponding to the front side of the first belt conveyor 2 to facilitate the feeding of vegetables onto the conveyor belt of the first belt conveyor 2; the cleaning nozzle 5 is divided into a high-pressure nozzle and a fine spray nozzle, which are selected and installed on the cleaning pipe 4 according to the type of vegetables to be pretreated. For example, when cleaning root vegetables and other vegetables with a lot of mud, a high-pressure nozzle is selected for cleaning, and the stubborn mud is efficiently removed by high pressure (water pressure is generally 0.4~0.8MPa); when cleaning leafy vegetables (such as spinach, celery, etc.) with a lot of pesticide residue, a fine spray nozzle is selected, and the cleaning water flow acts on the surface of the vegetable leaves in a "fan-shaped mist and columnar" composite form (water pressure is generally 0.3~0.4MPa, and the lower water pressure can effectively protect the leaves), quickly dispersing the mud and pesticides and other impurities on the surface.

[0023] According to the above design, during pretreatment, after the vegetables are placed onto the conveyor belt of the first belt conveyor 2 according to the preset units, the vegetables are transported backward. The three-way water distribution valve 7 is adjusted to connect its first interface with its second interface. At the same time, the first shut-off valve 9 is opened, and the water source pump 6 and the booster pump 8 are turned on to perform high-pressure rinsing on the vegetables. Alternatively, the three-way water distribution valve 7 is adjusted to connect its first interface with its third interface. At the same time, the second shut-off valve 10 is opened, and the water source pump 6 and the vegetable cleaner additive 11 are turned on to add vegetable cleaner and perform low-pressure rinsing on the vegetables.

The first hot-melt mechanism is fixed on the packaging platform 19 and is located above the second belt conveyor 20. The first hot-melt mechanism is used to weld the left and right sides of the packaging film conveyed by the second belt conveyor 20, and also plays a certain role in backward transmission. The second heat-sealing mechanism is fixed on the packaging platform 19 and is located between the second belt conveyor 20 and the second support plate 41. The second heat-sealing mechanism is used to periodically cut and seal the packaging film after it has passed through the first heat-sealing mechanism.

[0036] During pretreatment, a collection frame is placed below the second support plate 33.

[0037] Specifically, the first welding mechanism includes a substrate 21, a first hot melt assembly, two clamping wheel sets, and a first driver 26.

[0039] In this embodiment, for example, the second hot melt assembly includes a hot melt roller 27 and two second hot melt blocks 28 symmetrically fixed on the hot melt roller 27.

[0040] According to the above design, before pretreatment, the packaging film on the film supply roller 21 is pulled onto the first support plate 41, and its left and right sides are overlapped before being placed into the first hot-melt mechanism; during pretreatment, the washed vegetable units fall onto the first support plate 41 in sequence and are conveyed backward with the packaging film, and then fall onto the second support plate 33 in sequence. During the conveyance of the vegetable units, the left and right sides of the packaging film are first welded by the first welding mechanism, and then the packaging film is periodically cut and sealed by the second welding mechanism to form a complete package.
