[0038] Below with reference to accompanying drawing some embodiment of the present utility model is described:

[0039] like Figures 1-6 As shown, the utility model proposes a conveying mechanism, including a frame, a conveyor belt and a conveyor assembly arranged on the frame, the conveyor assembly being arranged above the conveyor belt, the conveyor assembly being divided into two groups, the two groups of conveyor assemblies being symmetrically arranged along the vertical center plane of the conveyor belt, and the spacing between the two groups of conveyor assemblies being smaller than the width of the conveyor belt, and the conveying distance of the conveyor assembly being greater than the conveying distance of the conveyor belt;

[0040] The tableware is placed on this mechanism before entering the dishwasher. The tableware with a maximum diameter smaller than the distance between the two sets of conveying components 3, such as glass cups, will be conveyed out of the mechanism by the conveyor belt 2; while the tableware with a minimum diameter larger than the distance between the two sets of conveying components 3, such as Jiangzhong cups, will be driven by the conveyor component 2 to continue moving forward. The tableware on the conveyor belt 2 and the tableware on the conveyor component 2 are conveyed out of the mechanism at different positions, so that tableware of different shapes can be separated.

[0041] Furthermore, the transmission component 3 includes a support bar 301, a driving wheel 302, a driven wheel 303, a fixing member 306 and a first belt 307. The support bar 301 is fixedly installed on the frame 1. The length of the support bar 301 is greater than the length of the conveyor belt 2. The driving wheel 302 is arranged at one end of the support bar 301. The fixing member 306 is fixedly installed at the other end of the support bar 301. The driven wheel 303 is rotatably connected in the fixing member 306. The first belt 307 is simultaneously mounted on the driving wheel 302 and the driven wheel 303, and the first belt 307 is against the support bar 301. An installation groove 3061 is opened on the fixing member 306, and the driven wheel 303 is rotatably connected in the installation groove 3061.

[0042] According to the length of the conveyor belt 2, multiple support bars 301 can be horizontally spliced ​​to meet the purpose of transmission and separation; a tensioning shaft 304 and a first bearing 305 are provided in the driven wheel 303, and the tensioning shaft 304 can be disassembled in the fixing part 306, and the shaft is coaxially sleeved on the tensioning shaft 304, and the inner ring of the first bearing 305 is fixedly installed on the tensioning shaft 304, and the driving wheel 302 is coaxially fixedly installed on the outer ring of the first bearing 305.

[0043] By adjusting the installation position of the driven wheel 303 in the installation slot 3061, the tightness of the first belt 307 can be adjusted;

[0044] Furthermore, if Figure 1 and Figure 2 As shown, the conveying component 3 also includes a second belt 308 installed in the same manner as the first belt 307. The horizontal plane where the second belt 308 is located is higher than the horizontal plane where the first belt 307 is located. The conveying speeds of the first belt 307 and the second belt 308 are the same, and there is a difference in conveying speed between the first belt 307 and the second belt 308 and the conveyor belt 2.

[0045] By setting the first belt 307 and the second belt 308, the contact area between the first belt 307 and the second belt 308 and the tableware can be increased, thereby increasing the friction on the tableware, and further improving the transportation efficiency of the tableware by the device; at the same time, the first belt 307 and the second belt 308 can also protect the tableware, reduce the contact between the tableware and the support bar 301, and thus reduce the wear of the tableware.

[0046] The difference in transmission speed between the first belt 307, the second belt 308 and the conveyor belt 2 is within 25%. Specifically, the transmission speed range of the conveyor belt 2 is between 75% and 100% of the transmission speed of the first belt 307 and the second belt 308. Through such a setting, under the action of the first belt 307 and the second belt 308, the posture of the tableware on the conveyor belt 2 can be adjusted, thereby facilitating the separation of different tableware on the conveyor belt 2.

[0047] Furthermore, if Figure 3 As shown, the support bar 301 is provided with a first limiting groove 3011 for limiting the first belt 307 and a second limiting groove 3012 for limiting the second belt 308 .

[0052] By setting the driving mechanism, one driving member 4 can drive two groups of transmission components 3 to move toward each other synchronously at the same time. The driving member 4 is preferably a servo motor.

[0053] Furthermore, if Figure 6As shown, the mounting assembly 5 includes a mounting frame 501, a support rod 502, a first mounting piece 503 and a second mounting piece 504.

The mounting frame 501 is fixedly mounted on the rack 1, and the support rod 502 is vertically fixedly mounted in the mounting frame 501.

[0054] The first mounting piece 503 and the second mounting piece 504 are both L-shaped. By installing the first mounting piece 503 and the second mounting piece 504 on the frame 1, the vertical mounting position of the driving mechanism can be adjusted according to the size of the tableware to be separated, and the mounting position of the conveying assembly 3 on the frame 1 can be adjusted according to the position of the driving mechanism, thereby avoiding collision between different tableware when separating the tableware and reducing the risk of damage to the tableware.

[0055] Furthermore, if Figure 5 As shown, the transmission assembly 6 includes a relay shaft 601, a first main shaft 602, a second main shaft 603, a first sprocket 606, a second sprocket 607, a third sprocket 608, a first spur gear 609, a second spur gear 610, a third belt 611 and a fourth belt 612;

The fourth belt 612 is sleeved on the second sprocket 607 and the third sprocket 608. The first spur gear 609 and the second spur gear 610 are coaxially fixedly mounted on the relay shaft 601 and the second main shaft 603, respectively, and the first spur gear 609 is meshed with the second spur gear 610.

[0057] The transmission assembly 6 is arranged on the relay shaft 601, the first main shaft 602 and the second main shaft 603, and the driving wheels 302 in the transmission assembly 3 on both sides of the conveyor belt 2 are respectively arranged on the first main shaft 602 and the second main shaft 603.

[0058] The first main shaft 602, the second main shaft 603 and the relay shaft 601 are all rotatably connected to the work frame through the flange 604 and the second bearing 605. When the driving member 4 is working, it drives the first sprocket 606 to rotate synchronously, and the first sprocket 606 drives the third belt 611 to move synchronously. When the third belt 611 moves, it drives the second sprocket 607 on the first main shaft 602 to rotate synchronously. When the second sprocket 607 rotates, it drives the first main shaft 602 to rotate synchronously, and can drive the driving wheel 302 on the first main shaft 602 to rotate synchronously, thereby driving the first belt 307 and the second belt 308 on one side to move synchronously;
