[0046] Example:

[0047] like Figure 1 As shown, an embodiment of the present application discloses a rectifier bridge sheet discharging and anti-jamming mechanism, which is used to discharge sheets and convey the frame of the rectifier bridge, and its specific structure includes: a sheet discharging structure 1, a plurality of turnover material boxes 2 and a plurality of lifting structures 3.

[0048] Specifically, Figure 7 As shown, the film arrangement structure 1 includes:

[0049] The lifting plate 11 is arranged horizontally and has a rectangular structure with high regularity. A plurality of movable channels 111 evenly spaced side by side are provided on the top surface. The movable channels 111 are rectangular and arranged along the long axis direction, thereby improving the compactness of the structure.

[0050] The support assembly 12 is installed on the bottom surface of the lifting plate 11 , and can drive the lifting plate 11 to perform lifting motion under the drive of the lifting mechanism, thereby playing a role in supporting the lifting plate 11 .

[0051] A plurality of limiting plates 13 are arranged vertically and evenly spaced side by side on the top surface of the lifting plate 11, and a sheet arrangement station 1A is formed between two adjacent limiting plates 13, and the sheet arrangement station 1A corresponds to the movable channel 111 one by one; the sheet arrangement station 1A is used to place the turnover material box 2, and plays the role of left and right limiting.

[0052] Specifically, Figures 1 to 3 and Figures 4 to 6 As shown, a plurality of turnover material boxes 2 are placed one by one at the film arrangement station 1A, the turnover material boxes 2 are open at the front and rear, and a plurality of wire grooves 21 evenly spaced up and down are opened on both sides of the inner wall, a hollow opening 22 is opened at the bottom, and a plurality of vertical rods 23 are installed inside the rear end.

[0053] It should be noted that the two left and right wire grooves 21 located in the same horizontal plane jointly support a frame; thereby, multiple frames can be evenly spaced up and down; the vertical rod 23 plays a limiting role to prevent the frame from falling out from the rear end; the hollow opening 22 is used to allow the lifting structure 3 to extend into the interior of the turnover material box 2.

[0054] Specifically, Figures 1 to 7 As shown, a plurality of lifting structures 3 are arranged one by one below the movable channel 111 , and the lifting structures 3 include: support columns 31 and lifting blocks 32 .

[0055] The support column 31 is arranged vertically; the top material block 32 is arranged horizontally and installed on the top of the support column 31, and has convex strips 321 on the left and right sides of the top surface.

[0057] During installation, the support assembly 12 is connected to the driving end of the lifting mechanism, and the bottom ends of the plurality of lifting structures 3 are fixed to the ground, so that the lifting structures 3 can be kept in a vertical fixed state. Then, a pushing device is arranged on one side of the sheet arrangement and anti-jamming mechanism, and a hooking device is arranged on the other side.

[0058] During operation, the turnover material boxes 2 are placed one by one on the film arrangement station 1A, and the rear end is located on the side close to the pushing device, and the front end is located on the side close to the hooking device. Then, under the drive of the lifting mechanism, the support assembly 12 drives the lifting plate 11 to move downward, so that the lifting structure 3 extends into the turnover material box 2 through the movable channel 111 and the hollow opening 22. When the frame at the bottom of the turnover material box 2 is lifted by the convex strip 321 on the top of the lifting block 32 and no longer overlaps the wire grooves 21 on the left and right sides, the lifting mechanism stops moving; at this time, the pushing device is started, and the pushing device extends a push rod, which extends from the rear end into the turnover material box 2, partially pushing the frame out of the turnover material box 2, and then resets; at the same time, the hooking device is started, and the hooking device hooks the part where the frame is pushed out, and then the frame is completely pulled out of the turnover material box 2, and is released after being pulled to the appropriate position.

[0059] The utility model provides a lifting structure 3 so that the lifting block 32 can extend into the turnover box 2 through the movable channel 111 and the hollow opening 22, and uses the convex strip 321 to support the area on the bottom surface of the lowermost frame where no jumper wires or grains are arranged, so that the frame is no longer overlapped on the wire grooves 21 on the left and right sides. Therefore, when the turnover box 2 is translated and transported, the jumper wire will not get stuck on the track and the grain will not be squeezed and damaged, thereby avoiding damage to the material, reducing the scrap rate of the material, greatly improving the discharge smoothness rate, and greatly improving the production efficiency.

[0060] In some embodiments, Figures 1-2 and Figures 4-5 As shown, the support assembly 12 includes: a support plate 121 and a plurality of connecting columns 122 .

[0061] Specifically, the support plate 121 is preferably rectangular with good structural regularity; a plurality of limiting grooves 1211 are provided on its top surface, and the limiting grooves 1211 correspond one-to-one to the support columns 31, which play a limiting and guiding role and improve the stability of the lifting movement.

[0062] Specifically, multiple connecting columns 122 are provided between the lifting plate 11 and the support plate 121; the number is preferably four, and they are arranged at the four corners of the support plate 121, which has the advantage of stable support, but is not limited to this, and can be six or more, without specific limitation.

[0063] Through the further design of the structure of the supporting assembly 12, the stable support of the lifting plate 11 is guaranteed, the stability of the lifting movement is improved, and the equipment failure rate is reduced.

[0067] The above arrangement plays a role in supporting the turnover material box 2, and after being worn out due to long-term use, it can be disassembled and replaced, thereby extending the service life of the device and facilitating maintenance and repair.

[0068] Based on the above embodiments, Figure 3 As shown, a plurality of mounting grooves 112 corresponding to the backing plates 14 are formed on the top surface of the lifting plate 11 .

[0069] By providing the installation groove 112 , the pad 14 can be conveniently and quickly arranged at a suitable position during assembly, thereby improving assembly efficiency and reducing the difficulty of equipment debugging.

[0073] It should be noted that the areas on the bottom surfaces of different frames where jumpers or crystal grains are not arranged are located at different positions, so the top material blocks 32 adapted thereto are also different and need to be replaced accordingly in actual use.

[0074] Through the above design, the bolt connection between the top material block 32 and the support column 31 is realized, which will not interfere with the lifting of the top material block 32 and is easy to disassemble and replace, so as to facilitate the replacement of unused top material blocks 32 to adapt to the use of different frames, thereby improving the applicability of the device.
