[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1

[0032] See also Figures 1 to 5 As shown, a circulating tray conveying mechanism in an embodiment of the present invention includes a machine platform 1, a fixed conveying line 2 is arranged above the machine platform 1, and a lifting conveying line 3 is arranged inside the fixed conveying line 2.

[0033] The fixed conveyor line 2 includes a frame 21 fixedly connected to the machine 1 , and both sides of the interior of the frame 21 are rotatably connected to a plurality of conveyor wheels 22 arranged at intervals, and the plurality of conveyor wheels 22 are driven by a motor 24 .

[0034] The lifting conveyor line 3 includes a lifting plate 31 that can be lifted and lowered. Side plates 32 are fixedly connected to both sides of the lifting plate 31. The inner sides of the two side plates 32 are rotatably connected to multiple spaced conveying wheels 2 34. The conveying wheels 2 34 on the same side are transmitted by a transmission assembly 35. Multiple conveying wheels 2 34 are driven by a driving assembly 36. The conveying wheels 2 34 and the conveying wheels 1 22 are arranged at 90 degrees, and the conveying wheels 2 34 at both ends can pass through the gap between the conveying wheels 1 22. The upper ends of the conveying wheels 2 34 and the upper ends of the side plates 32 are located in the same horizontal plane. When the conveying wheel 1 22 is raised, it will not be interfered by the conveying wheels 2 34. The upper surface of the side plates 32 is smoothly arranged with low friction, which is convenient for the material tray to enter and the conveying of the conveying wheels 2 34.

[0035] The lifting conveyor line 3 also includes a fixed plate 33 arranged below the lifting plate 31. The fixed plate 33 is fixedly connected to the machine platform 1, and an electric cylinder 38 is fixed to the lower end surface. The protruding end of the electric cylinder 38 is fixedly connected to the lifting plate 31. Guide rods 39 are fixed at the four corners of the lower end surface of the lifting plate 31. The guide rods 39 are slidably connected to the fixed plate 33, and the lifting plate 31 is driven to rise and fall by the action of the electric cylinder 38. The guide rods 39 are provided to play a restraining role to ensure that the lifting plate 31 will not deflect when it is lifted or lowered.

[0036] Among them, the transmission assembly 35 includes a plurality of single-row sprockets 351 respectively fixedly connected to the conveying wheel 2 34, and the plurality of single-row sprockets 351 are driven by a long chain 352. Two tensioning sprockets 353 are rotatably arranged between adjacent single-row sprockets 351, and the tensioning sprocket 353 is meshed and connected with the long chain 352. The driving assembly 36 includes a motor 2 361 and a transmission shaft 2 362. The motor 2 361 and the transmission shaft 2 362 are driven by a sprocket chain. The two ends of the transmission shaft 2 362 are respectively fixed to the conveying wheels 2 34 on both sides. When the lifting conveyor line 3 is conveying, the motor 2 361 is driven to drive the conveying wheel 2 34 connected to the transmission shaft 2 362 to rotate. The remaining conveying wheels 2 34 are connected by the transmission assembly 35 and will rotate synchronously, thereby synchronously conveying the material tray. The rotation direction of the conveying wheel 2 34 is changed by controlling the forward and reverse rotation of the motor 2 361 to convert the conveying direction of the lifting conveyor line 3.

[0037] In order to protect the second motor 361 from collision, a sleeve 363 is provided on the outer end cover of the second motor 361 , and ventilation holes are provided on both sides of the sleeve 363 .

[0038] In this example, see Figure 1 As shown, during installation, the fixed conveyor line 2 and the lifting conveyor line 3 are respectively connected to the external conveyor line 1 5 and the external conveyor line 2 6, wherein the height of the conveying wheel of the external conveyor line 1 5 is the same as the height of the conveying wheel 1 22, and the height of the upper surface of the conveying wheel of the external conveyor line 2 6 is the same as the height of the upper surface of the frame 21. Through the above arrangement, if the material tray enters from the external conveyor line 1 5, after the material tray is fed into the fixed conveyor line 2, the lifting conveyor line 3 rises until the side plate 32 is flush with the frame 21, and then the conveying wheel 2 34 rotates, thereby conveying the material tray to the external conveyor line 2 6;

[0039] If the material tray enters from the external conveyor line 2 6, the lifting conveyor line 3 is first raised to receive the material tray, and then lowered after the material plate is in place, and the material tray is lowered to the conveying wheel 1 22 of the fixed conveyor line 2, and the conveying wheel 1 22 rotates to convey the material tray to the external conveyor line 1 5. The material tray is flexibly transferred between the two external conveyor lines, so that the material tray can be quickly circulated and transported.

[0040] Embodiment 2

[0041] Based on Example 1, please refer to Figures 2 to 4 as well as Figure 6 As shown, positioning components 37 are provided on both sides of the lifting plate 31 close to the conveying wheel 22. The positioning components 37 themselves can be raised and lowered to position the material tray.

[0042] Specifically, the positioning assembly 37 includes a cylinder 371 fixedly connected to the lower end surface of the lifting plate 31, the protruding end of the cylinder 371 is fixedly connected to a positioning plate 372 arranged above the lifting plate 31, the upper end surface of the positioning plate 372 is fixed with a positioning column corresponding to the hole position below the material tray, and the two sides of the positioning plate 372 are fixedly connected with a guide rod 373 slidably sleeved with the lifting plate 31. Before the lifting conveyor line 3 is lifted, the positioning plate 372 can be lifted first, so that the positioning column of the positioning plate 372 is plugged into the corresponding hole position at the bottom of the material tray, thereby ensuring the stability of the material tray when it is lifted later.

[0043] Gaps are left between both ends of the lifting conveyor line 3 and the fixed conveyor line 2, a blocking component 4 is installed in the gap close to the output direction of the fixed conveyor line 2, a motor 24 is fixedly arranged in another gap, and the output end of the motor 24 is connected to a transmission shaft 23 through a sprocket chain transmission, and the two ends of the transmission shaft 23 are respectively fixed to two conveying wheels 22, and double-row sprockets 25 are fixed to the outer ends of multiple conveying wheels 22, and adjacent double-row sprockets 25 are driven by a short chain 26. The remaining gap leaves installation space for the motor 24 and the blocking component 4. When the fixed conveyor line 2 is working, it is driven by the motor 24 to drive the two conveying wheels 22 connected to the transmission shaft 23 to rotate. Since the conveying wheels 22 are driven by the double-row sprockets 25 and the short chain 26, the multiple conveying wheels 22 are driven to rotate synchronously to stably convey the material tray.

[0044] Among them, the blocking component 4 includes a mounting plate 41 fixedly connected to the machine table 1, and a cylinder 42 is fixed to the lower end surface of the mounting plate 41. The protruding end of the cylinder 42 passes through the mounting plate 41 and is fixed with a blocking frame 43. The two sides of the blocking frame 43 are slidably connected with the mounting plate 41. When the blocking component 4 is in use, the blocking frame 43 is driven to rise and fall by the cylinder 42. When it is raised, it is in a blocking state. After the blocking frame 43 is raised, it can limit the material tray entering from the direction of the lifting conveyor line 3 to ensure that the material tray is not easily skewed when entering the lifting conveyor line 3.

[0045] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
