[0084] The guide opening A42 and the guide opening B43 are both used to allow the U-shaped push rod 9-3-2 on the shifting rod 9 to pass through.

[0085] The working stations of the loading platform 2, the spray cleaning device 3, the ultrasonic cleaning device 4, the steam cleaning device 5 and the drying device 6 have the same length; when the screw nut A13 moves from one end of the screw A11 to the other end of the screw A11, the tray 10 is pushed by the torsion spring propulsion mechanism 9-3 to move from the loading platform 2 to the working station of the spray cleaning device 3, or from the spray cleaning device 3 to the working station of the ultrasonic cleaning device 4, or from the ultrasonic cleaning device 4 to the steam cleaning device 5, or from the steam cleaning device 5 to the working station of the drying platform 6, or from the drying platform 6 to the working station of the unloading platform 7.

[0086] Since the torsion spring propulsion mechanism 9-3 is characterized in that it is only used to push the tray 10 to the next cleaning station, but cannot push the tray 10 from the current station to the previous station in the reverse direction;

[0087] When the torsion spring propulsion mechanism 9-3 pushes the tray 10 from the current station to the next station, one end of the torsion spring 9-3-5 is stuck in the U-shaped slot 9-3-6, and the other end of the torsion spring 9-3-5 is pressed against the stop rod 9-3-4 (see Figure 5 ), therefore, the U-shaped push rod 9-3-2 can push the tray 10 to the next station;

[0088] When the torsion spring propulsion mechanism 9-3 returns from the current station to the previous station, for example, when the first batch of trays 10 loaded with tableware moves from the loading platform 2 to the station where the spray cleaning device 3 is located, in order to continue to transport the next batch of tableware (the cleaning production line continuously and uninterruptedly cleans the tableware during the cleaning process), the torsion spring propulsion mechanism 9-3 initially located at the loading platform 2 must return to its original position. During the process of returning to its original position, the torsion spring propulsion mechanism 9-3 will inevitably contact the tray 10. During the return process, the U-shaped push rod 9-3-2 moves in a direction away from the baffle rod 9-3-4. At the same time, the stiffness coefficient of the torsion spring 9-3-5 is 0.5-1N / m, which is not enough to generate elastic force to push the tray 10 back to its original position. Therefore, the tray 10 can only run from the current station to the next station, and cannot be pushed back to the previous station from the current station by the U-shaped push rod 9-3-2.

[0089] When the U-shaped push rod 9-3-2 passes through the drying device 6, it passes through the guide openings A42 on the opposite sides of the drying box 6-1;

[0090] When the U-shaped push rod 9-3-2 passes through the spray box 15 on the spray cleaning device 3 and the spray box 15 of the steam cleaning device 5, it passes through the guide openings B43 on the opposite sides of the spray box 15.

[0091] The working process of a tableware washing line of the present invention is as follows: the tableware to be washed is placed on a tray 10, and a partition frame is provided on the tray 10, and a tableware is placed in each partition frame; then the tray 10 is placed on the tray bracket 8 of the station where the loading platform 2 is located, the motor A12 rotates forward, the screw A11 rotates, and drives the screw nut A13 to move, and the screw nut A13 drives the torsion spring propulsion mechanism 9-3 on the lever 9 to move along the washing line, at this time, the torsion spring propulsion mechanism 9-3 located at the starting end of the station of the loading platform 2 pushes the tray 10 along the tray bracket 8 to the station where the spray cleaning device 3 is located, at this time, the motor B22 at the spray cleaning device 3 rotates forward, and the double-groove rotating wheel A21 drives the two lifting doors A20 to move upward through the lifting rope A23 and the lifting rope B24 respectively, and the opening A19 is opened, and the torsion spring propulsion mechanism 9-3 moves the tray 10 from the station where the loading platform 2 is located to the station where the spray cleaning device 3 is located;

[0092] After the tableware enters the station where the spray cleaning device 3 is located along with the tray 10, the lifting door A20 descends to close the opening A19 to prevent the cleaning liquid from splashing. At this time, the motor A12 reverses, the lead screw A11 moves in the opposite direction with the lead screw nut A13, and the torsion spring propulsion mechanism 9-3 on the lever 9 also moves in the opposite direction along with the lead screw nut A13, and the torsion spring propulsion mechanism 9-3 located at the starting end of the loading station 2 returns to the initial position;

[0093] The water pump 31 is turned on, and the cleaning water tank 33 is pre-configured with cleaning liquid. The cleaning liquid in the cleaning water tank 33 is pumped into the water inlet pipe 30 through the water pump 31, and is transported to each branch duct 32 through the water inlet pipe 30. The cleaning liquid in each branch duct 32 is sprayed out through the nozzle 18. Since the nozzles 18 are arranged at the top, bottom, left and right positions in the spray box 15, the tableware in the tray 10 can be washed in all directions; the washed cleaning liquid can be returned to the cleaning water tank 33 through the return port on the support plate A for repeated use; at the same time, the food residue in the tableware after washing is filtered out through the filter plate 34; after washing;

[0094] The motor B22 rotates forward, driving the lifting door A20 to open. At the same time, the motor A12 rotates forward, driving the screw nut A13 to move through the screw A11, and the screw nut A13 drives the lever 9 to move. At this time, the torsion spring propulsion mechanism 9-3 located at the spray cleaning device 3 station pushes the tray 10 at the current station to move toward the ultrasonic cleaning device 4. After the tray 10 with tableware reaches the tray bracket 8 on the ultrasonic cleaning device 4, the motor A12 reverses, the screw nut A13 returns to the initial position, and the torsion spring propulsion mechanism 9-3 at the spray cleaning device 3 station also returns to the initial position;

[0095] At the same time, the motor C13 rotates forward, the transmission shaft 4-2 rotates, and at the same time drives the two bevel gears A4-3 to move. The two bevel gears A4-3 are respectively meshed with the bevel gear B4-4, and the bevel gear B4-4 drives the screw B4-5 to rotate, and the screw nut B4-6 moves on the screw B4-5, and at the same time drives the tray bracket 8 and the docking frame 4-8 to form a square frame body to move downward, and the tray 10 with the tableware descends along the square frame body to the ultrasonic tray 4-11 in the cleaning box 4-1, and the tableware on the tray 10 is ultrasonically cleaned through the interaction between the water in the cleaning box 4-1 and the transducer 4-12; after the cleaning is completed, the motor C13 flips over and drives the square frame body to rise to the initial position through the screw nut B4-6;

[0096] On the spray box 15 located at the steam cleaning device 5, the motor B22 rotates forward, driving the lifting door A20 to open. At the same time, the motor A12 rotates forward, driving the screw nut A13 to move through the screw A11, and the screw nut A13 drives the lever 9 to move. At this time, the torsion spring propulsion mechanism 9-3 located at the station of the ultrasonic cleaning device 4 pushes the tray 10 on the current station to move onto the steam cleaning device 5. After the tray 10 with tableware reaches the tray bracket 8 on the steam cleaning device 5, the motor A12 reverses, and the screw nut A13 returns to its original position. The torsion spring propulsion mechanism 9-3 at the ultrasonic cleaning device 4 station also returns to the initial position; the motor B22 reverses to drive the lifting door A20 to fall. At this time, the heating rod is energized to heat the water in the water tank 39. The water vapor generated after heating is transported to the branch ducts 32 in the spray box 15 through the air guide pipe 40. The cleaning liquid in each branch duct 32 is sprayed out through the nozzle 18. Since the nozzles 18 are arranged at the top, bottom, left and right positions in the spray box 15, the tableware in the tray 10 can be fully steam sterilized;

[0097] After the disinfection is completed, the motor B22 reverses and the lifting door A20 opens. At the same time, the motor D6-6 rotates forward, the lifting door B6-4 opens, and the motor A12 rotates forward, driving the screw nut A13 to move through the screw A11, and the screw nut A13 drives the lever 9 to move. At this time, the torsion spring propulsion mechanism 9-3 located at the steam cleaning device 5 station pushes the tray 10 on the current station to move to the drying device 6. After the tray 10 with tableware reaches the tray bracket 8 on the drying device 6, the motor A12 reverses, the screw nut A13 returns to the initial position, and the torsion spring propulsion mechanism 9-3 at the steam cleaning device 5 station also returns to the initial position; the motor D6-6 reverses to drive the lifting door B6-4 to close. At the same time, the fan 6 -2 is turned on to blow air into the drying box 6-1 to dry the tableware on the tray 10 in the drying box 6-1; after drying is completed, the motor D6-6 rotates forward to drive the lifting door B6-4 to open, and the motor A12 rotates forward to drive the screw nut A13 to move through the screw A11, and the screw nut A13 drives the lever 9 to move. At this time, the torsion spring propulsion mechanism 9-3 located at the station of the drying device 6 pushes the tray 10 on the current station to move to the lower feeding table 7. After the tray 10 loaded with tableware reaches the tray bracket 8 on the lower feeding table 7, the motor A12 reverses, the screw nut A13 returns to the initial position, and the torsion spring propulsion mechanism 9-3 at the station of the drying device 6 also returns to the initial position; at this time, one cycle of cleaning work is completed.

[0098] The tableware washing line of the present invention can also be used to wash machined parts and is applied to the field of mechanical parts washing. A plurality of squares are evenly arranged on the tray 10, and tableware or parts to be washed are placed in each square. The bottom of the square is a hollow structure, which is convenient for the washing liquid to flow out and for the nozzle to spray water upward from the bottom.
