During working, the first vacant fixed conveying line 4a is close to the first feeding and discharging station 3a, the second vacant fixed conveying line 4b with materials is close to the second discharging station 3b, the first feeding and discharging station 3a can convey the first products 5a to the position above the first fixed conveying line 4a until the first products 5a are stopped by the front stopping mechanism 42a, the first fixed conveying line 4a carries materials, meanwhile, the second fixed conveying line 4b can convey the second products 5b to the second discharging station 3b, and the second fixed conveying line 4b is vacant; after the feeding and discharging action is completed, the driving motor 21 enables the rotating platform 22 to rotate 180 degrees, at the moment, the first fixed conveying line 4a is close to the second feeding and discharging station 3b, meanwhile, the second fixed conveying line 4b is close to the first feeding and discharging station 3b, and the reversing operation can be continuously performed by repeating the actions. Because the operation of discharging is carried out while the feeding is stopped, so time is saved, the action is simple, the error rate is low, and the working efficiency is high. In practical application, the materials can be discharged from the first feeding and discharging station 3a, and the materials can be fed from the second feeding and discharging station 3 b; and three or more than three fixed conveying lines can be arranged on the rotating station 2, and three or more than three feeding and discharging stations can be arranged. Therefore, the front and back feeding directions of the products can be adjusted, and the distribution operation of multiple production lines can be carried out.

As shown in fig. 2, the machine table 1 is provided with a circular guide rail 11 centered on a vertical axis, and the bottom of the rotary platform 22 is provided with a slider 221 engaged with the circular guide rail 11. The circular guide rail 11 can make the rotary platform 22 move precisely according to a circular track, so as to prevent the product from shaking and sliding when rotating due to uneven stress on the rotary platform 22.

As shown in fig. 4, the first fixed conveying line 4a and the second fixed conveying line 4b are further provided with a rear blocking mechanism 42b located on one side of the conveying mechanism 41 away from the vertical axis, each of the front blocking mechanism 42a and the rear blocking mechanism 42b includes an L-shaped blocking block 421 and a blocking cylinder 422 for driving the blocking block 421 to ascend and descend, the front blocking mechanism 42a is provided with a front sensing mechanism 43a on one side away from the vertical axis, the rear blocking mechanism 42b is provided with a rear sensing mechanism 43a on one side away from the vertical axis, and the device controller controls the front blocking mechanism 42a and the rear blocking mechanism 42b to ascend and descend according to signals received by the front sensing mechanism 43a and the rear sensing mechanism 43 b. The front sensing mechanism 43a and the rear sensing mechanism 43b may be a photoelectric sensor, an optical fiber sensor, or other mechanisms capable of detecting whether an object passes through the sensing area, and the detection direction is not limited to the horizontal direction, and may be the vertical direction. The front blocking mechanism 42a and the rear blocking mechanism 42b control the product to pass through by using the lifting of the blocking block 421, and the L-shaped structure of the blocking block 421 has a limiting effect on the front and rear directions of the product. When the first fixed conveying line 4a and the second fixed conveying line 4b just rotate to be in place, the rear blocking mechanism 42b can be in a falling state, products can normally pass through the upper portion of the rear blocking mechanism 42b until the rear blocking mechanism 42a contacts, the products can be detected by the front sensing mechanism 43a at the moment, the rear sensing mechanism 43b cannot sense the products, the rear blocking mechanism 42b can rise, the products can be clamped between the front blocking mechanism 42a and the rear blocking mechanism 42b, and at the moment, the products can be blocked by the blocking block 421 in the rotating process of the rotating platform 22 and are not easy to slide. If this rotary conveying mechanism does not carry out the product and turns to the operation, also can let preceding barrier mechanism 42a and back barrier mechanism 42b fall together, first fixed transfer chain 4a and the fixed transfer chain 4b of second use as the whole section transfer chain of linking from beginning to end, let the product directly pass through first business turn over material station 3a, rotatory station 2 and second business turn over material station 3b in proper order and move backward.

When the rotary platform 22 rotates, the air cylinder 32 drives the butt joint conveying line 31 to move in a direction away from the rotary platform 22, so that the butt joint conveying line 31 is prevented from colliding with a product; when the docking conveyor line 31 is aligned with the first fixed conveyor line 4a or the second fixed conveyor line 4b, the air cylinder 32 can make the docking conveyor line 31 close to the rotary platform 22, so as to prevent the docking conveyor line 32 from being too far away from the first fixed conveyor line 4a or the second fixed conveyor line 4b to cause the product to fall.

As shown in fig. 2 to 4, the conveying mechanism 41 includes a substrate 411, a fixed support 412 disposed on one side of the substrate 411, a support plate 413 disposed on the other side of the substrate 411, a movable support 414 movable between the fixed support 412 and the support plate 413, and a driving unit 415 for moving the movable support 414, a pair of slide rails 4111 for guiding the movable support 414 to translate perpendicularly to the conveying direction is disposed on the substrate 411, and belt conveying units (not labeled) are disposed on both the fixed support 412 and the movable support 414. The product is moved by means of two belt conveyor units. The driving unit 415 can adjust the position of the movable support 414 on the slide rail 4111, and thus control the distance between the fixed support 412 and the movable support 414, which determines the distance between the two belt conveying units. The drive unit 415 can control the spacing of the two belt conveyor units to accommodate the width of the product. The structure of the butt conveying line 31 may be the same as that of the first fixed conveying line 4a and the second fixed conveying line 4 b. Because the docking conveyor line 31 functions similarly to the

fixed conveyor lines

4a, 4b, the equipment can be assembled by using the same modular components, and the modular components can be used in series even if damaged, so that the maintenance is more convenient.

As shown in fig. 4, the front blocking mechanism 42a and the rear blocking mechanism 42b are fixed to the movable bracket 414. Thus, the front blocking mechanism 42a and the rear blocking mechanism 42b do not increase the limitation on the moving space of the movable bracket 414 due to the fixation on the base plate 411.

As shown in fig. 4, the driving unit 415 includes a screw 4151 rotatably connected between the fixed bracket 412 and the supporting plate 413 and a hand wheel 4152 at one end of the screw 4151, and the movable bracket 414 is provided with a nut (not exposed) threadedly engaged with the screw 4151. The combination of the screw rod and the nut can be replaced by a ball screw and other screw transmission mechanisms so as to improve the efficiency of converting rotation into linear movement; therefore, the distance between the two belt conveying units can be adjusted on site by using the hand wheel 4151 to adapt to the width of a product, and the control is convenient.
