[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0025] Embodiment 1:

[0026] Please refer to Figures 1-5 , a switch clamping system of a tableware cleaning device, including a frame 64, and also including a plurality of drive wheels 220 and a drive chain 54. The drive wheels 220 are rotatably connected to the frame 64. The drive chain 54 is sleeved on the drive wheels 220. A connecting shaft 53 is provided on the drive chain 54. The connecting shafts 53 are distributed at intervals. A grasping mechanism is provided on the connecting shaft 53. The grasping mechanism includes an abutting member 12 and a clamping member 11. The abutting member 12 is movably connected to the clamping member 11. A spoon handle 26 and a pulley 27 are provided on the abutting member 12. The pulley 27 is rotatably connected to the spoon handle 26. An opening and closing member 52 and a clamping release member 102 are respectively provided at both ends of the frame 64. The opening and closing member 52 is vertically arranged, and the clamping release member 102 is horizontally arranged and both are fixedly connected to the frame 64. The opening and closing member 52 is provided with an abutting head 51, and the clamping release member 102 is provided with a convex portion 155. The abutting head 51 and the convex portion 155 are arranged in an arc shape.

[0027] In addition, one end of the opening and closing member 52 is recessed inward to form a recessed portion 55.

[0028] The clamping member 11 is provided with at least two connecting holes 32. The connecting shaft 53 passes through the connecting holes 32 and both ends pass through the drive chain 54.

[0029] The clamping member 11 is provided with an outer edge convex portion 23, and the outer edge convex portion 23 is bent upward. At least two inner convex portions 24 are provided in the middle of the clamping member 11. The inner convex portions 24 are arranged at intervals. The clamping member 11 is provided with a rotation hole 34 and a rotation shaft 21. The rotation shaft 21 passes through the rotation hole 34. One end of the abutting member 12 is provided with an abutting portion 25. The abutting member 12 is rotatably connected to the rotation shaft 21 and is located between both ends of the clamping member 11. A resilient member 31 is sleeved on the rotation shaft 21. One end of the resilient member abuts against the abutting member 12 and the other end abuts against the clamping member 11. In this embodiment, the resilient member is a torsion spring.

[0030] The abutting member 12 is provided with a second outer edge convex portion 33, and the outer edge convex portion 33 is bent upward. With such a setting, the second outer edge convex portion 33 has a guiding effect, enabling tableware to enter the grasping mechanism more smoothly and preventing the tableware from getting stuck at the edge of the grasping mechanism.

[0031] One end of the frame 64 near the opening and closing member 52 is provided with a feeding device, and one end of the frame 64 near the clamping release member 102 is provided with a discharging device. The feeding device is provided with a feeding conveyor belt 61 and a feeding driving assembly, and the discharging device is provided with a discharging conveyor belt 101 and a discharging driving assembly.

[0032] Working principle of the switch clamping system:

[0033] Please refer to Figure 1 In order to make better use of the vertical space and enable the grasping mechanism to hold more tableware and enter the interior of the frame, the plurality of transmission wheels 220 are vertically distributed in multiple regions and are rotatably connected to the frame 64. The transmission chain 54 is sleeved on the transmission wheels 220, and the transmission chain 54 is arranged in a circuitous manner. By connecting a driving assembly to any one of the transmission wheels 220, the transmission chain 54 can be driven to rotate, causing the grasping mechanism on the transmission chain to perform a reciprocating circular motion. Generally, a motor can be used as the driving force for the driving assembly.

[0034] Please refer to Figures 2-3 As shown in, since a torsion spring 31 is sleeved on the rotating shaft 21, one end of the torsion spring 31 abuts against the abutting member 12, and the other end abuts against the clamping member 11. Therefore, when the grasping mechanism is not subjected to an external force, it remains in a clamped and closed state. When the transmission chain 54 rotates, the connecting shaft 53 and the grasping mechanism on the connecting shaft move from the lower end to the upper end of the opening and closing member 52. Since the opening and closing member 52 is fixedly connected to the frame 64, during the movement, the abutting head 51 of the opening and closing member 52 slides and abuts against the sliding wheel 27 of the spoon handle 26, causing the abutting member 12 to rotate around the rotating shaft 21, and the abutting portion 25 to tilt up, and the grasping mechanism is in an open state. When the grasping mechanism rises to the position of the recessed portion 55 of the opening and closing member 52, since the recessed portion 55 is recessed, the pressure on the abutting member 12 disappears, the torsion spring restores its deformation, and the grasping mechanism reclamps and is in a closed state.

[0035] Please refer to Figure 4, a feeding conveyor belt 61 is provided at the front end of the frame 64, and the feeding conveyor belt 61 is driven by a conveying motor 62 provided in the feeding drive assembly, so that the tableware on the conveyor belt is transported toward the grabbing mechanism. The tableware is transported on the feeding conveyor belt 61 in an inverted manner with its opening facing downward, and when it reaches the end of the feeding conveyor belt 61, it will slide into the grabbing mechanism in an open state. For the tableware entering the grabbing mechanism, since the opening of the tableware is facing downward, the inner convex portion 24 and the outer convex portion 23 of the clamping member 11 can limit the tableware to prevent the tableware from being displaced in the front, rear, left, and right horizontal planes in the grabbing mechanism; when the grabbing mechanism drives the tableware to rise to the position of the recessed portion 55 of the opening and closing member 52, the abutting member 12 is pressed down, and the abutting portion 25 abuts against the tableware to prevent the tableware from being displaced in the upper and lower positions.

[0036] See also Figure 5 , a loosening member 102 and a discharge conveyor belt 101 are provided at the rear end of the frame 64. The grabbing mechanism holding the tableware is driven by the transmission chain 54, and the sliding wheel 27 of the grabbing mechanism slides against the convex portion 155 of the loosening member. Under the action of the convex portion 155, the abutting portion 25 is tilted, the grabbing mechanism opens, and the tableware slides from the grabbing mechanism to the discharge conveyor belt 101 below. The discharge conveyor belt 101 is provided with a discharge conveying motor (not shown) provided in the discharge drive assembly to provide driving force, so that the tableware on the discharge conveyor belt 101 is transported toward the discharge port 150.

[0037] By cooperating with the feeding device and the discharging device through the grabbing mechanism, the tableware can be automatically fed and discharged without manual labor, thereby improving the cleaning efficiency and reducing the labor expenditure of personnel; and through the fixing method of the clamping member 11 and the abutment member 12, the tableware can maintain a stable clamping state during the cleaning process, which helps to improve the cleaning effect.

[0038] Embodiment 2:

[0039] See also Figure 1 A tableware washing device comprises a washing device 200, a high temperature pool 300, a drying device 400 and a switch clamping system according to any one of claims 1 to 5, wherein the washing device 200, the high temperature pool 300 and the drying device 400 are installed in a frame 64, and the switch clamping system is located within the working range of the washing device 200, the high temperature pool 300 and the drying device 400.

[0040] Specifically, the cleaning device 200 includes a spray head and a cleaning box. The spray head is located above the cleaning box, and the cleaning box is an open stainless steel water tank. When working, the spray head is connected to tap water to flush the tableware in the grabbing mechanism passing through the cleaning device 200 area to remove the residue on the tableware. The cleaning box is used to isolate the cleaning device 200 from the external equipment of the device, and is connected to a sewage pipe.

[0041] Specifically, the high-temperature tank 300 is filled with a high-temperature cleaning liquid. The high-temperature tank 300 is used for the second cleaning and high-temperature immersion disinfection of tableware. By high-temperature immersion in the high-temperature tank 300, the temperature of the surface of the tableware can be rapidly increased, so that after the tableware enters the working area of the next drying device 400, the drying efficiency of the tableware can be improved.

[0042] Specifically, the drying device 400 includes a hot air blower. The drying device 400 is used for drying the washed tableware.

[0043] The tableware cleaning equipment in the present invention effectively utilizes the vertical space, and the equipment has a compact structure and a small floor area, achieving the effect of saving space.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the specification of the present invention.
