[0031] The working principle is as follows:
[0032] When the turning conveyor is to be used, the first motor 2 and the second motor 5 installed outside the first conveyor frame 1 and the second conveyor frame 4 can be respectively operated to achieve the transmission rotation of the first conveyor rollers 3 and the second conveyor rollers 6 installed inside the first conveyor frame 1 and the second conveyor frame 4. When the first conveyor frame 1 is transmitting and rotating, it can drive the item to move towards the second conveyor frame 4. When the item is transmitted to the rear end of the first conveyor frame 1, the item will fall onto the top of the second conveyor rollers 6 at the upper end of the second conveyor frame 4. Furthermore, with the transmission rotation of the running second conveyor rollers 6, the right or left turning transmission of the item can be achieved to meet the transmission processing requirements of the item in different directions;
[0033] To ensure that when the item falls from the first conveyor frame 1 to the upper end of the second conveyor frame 4, it is not easy to have a falling problem. In this application, a falling prevention device 7 is provided in the middle of the upper end of the second conveyor frame 4. First, the adjustable blocking member 74 provided between the two pairs of left and right vertical plates 72 can achieve the closure between the two pairs of left and right vertical plates 72 through the transparent curtain 744 connected to the internal winding roller 743. In this way, when the item falls from the first conveyor frame 1 to the upper end of the second conveyor frame 4, it can be flexibly blocked by the transparent curtains 744 on both sides to avoid the lateral falling problem of the item. At the same time, in cooperation with the equally spaced blocking strips 73 between the left and right vertical plates 72 at the rear end, the rear side anti-falling out of the item can be achieved. Thus, through the blocking on the left and right sides and the rear side, it can be ensured that when the item falls from the first conveyor frame 1 to the upper end of the second conveyor frame 4, it can perform stable falling and turning transmission. Moreover, when the item stably falls to the second conveyor rollers 6 at the upper end of the second conveyor frame 4, due to the fact that the transparent curtain 744 is a flexible curtain as a whole, it can be ensured that when the item is driven by the transmission of the second conveyor rollers 6, it can stably pass through the lower end of the transparent curtain 744, avoiding the problem of the limitation of the item transmission process caused by the setting of the transparent curtain 744;
[0034] When preventing small items from falling, in order to prevent the transparent curtain 744 from blocking an excessively large area, which would prevent small items from passing through the lower end of the transparent curtain 744, the area of use of the transparent curtain 744 needs to be reduced. To this end, the rocker 746 installed at the middle part of the front side of the rotating shell 7451 can be used in advance to realize the rotation of the lower end of the connecting frame 741 and the connected winding roller 743. When the winding roller 743 rotates, the transparent curtain 744 is rolled up as a whole, thereby reducing the area of use of the transparent curtain 744. At the same time, when the winding roller 743 rolls up the transparent curtain 744, the pressure roller 7426 against the outer side of the transparent curtain 744 can cooperate with the elastic force of the compression spring 7424 provided on the outer side of the support rod 7422. To assist in pressing the rolled transparent curtain 744 and avoid the problem of the transparent curtain 744 being rolled loose, at the same time, as the diameter of the rolled transparent curtain 744 increases, the pressure roller 7426 will be pushed upward as a whole, and as the pressure roller 7426 moves upward, the connecting piece 7425 docked at the middle of the pressure roller 7426 will push up the docking rods 7423 connected on both sides of the top, so that the docking rods 7423 are moved upward and contracted along the support rod 7422 plugged in the middle of the upper end, and at the same time, the compression spring 7424 arranged on the outer side of the support rod 7422 is squeezed, so that the squeezed compression spring 7424 can not only strengthen the squeezing of the rolled transparent curtain 744 by the pressure roller 7426 again, but also provide elastic support for the subsequent recovery of the compression assembly 742;
[0035] After the rolling-up activity of the transparent curtain 744 is completed, it is necessary to grasp the vertical rod 7453 in the middle of the lower end of the shell 7451 and hold the gripping rod 7454 connected to the side to bring the gripping rod 7454 close to the vertical rod 7453, so that the first moving bar 7455 connected to the upper end of the gripping rod 7454 will move right accordingly, and at the same time, the first rack 7456 arranged on the side of the first moving bar 7455 will move right synchronously to mesh with the gear 7457 connected to the lower end of the transmission, so that the gear 7457 can drive the second rack 7458 connected to the bottom, so that the second rack 7458 can realize the left movement of the second moving bar 7459 The first moving bar 7455 and the second moving bar 7459 can move synchronously relative to each other. At the same time, the lock shaft 74510 arranged at the upper ends of the first moving bar 7455 and the second moving bar 7459 can be simultaneously moved out of the circular holes opened inside the two sides of the guide groove 747 to achieve a quick unlocking activity. At this time, the housing 7451 can be moved downward as a whole to make the slider 7452 arranged at the rear side of the housing 7451 move along the guide groove 747 to adjust the downward movement of the connecting frame 741 as a whole. Thus, the transparent curtain 744 that has completed the winding adjustment can be moved downward to the lower end position to adapt to the anti-drop and anti-transmission blocking of small items.
[0036] Secondly, when the first moving bar 7455 and the second moving bar 7459 are unlocked by relative movement, the spring 74511 connecting the middle parts will be compressed. After the downward adjustment is completed, the grip bar 7454 can be released to allow the compressed spring 74511 to rebound, automatically realizing the reverse movement and reset of the first moving bar 7455 and the second moving bar 7459, and automatically realizing the reinsertion and locking of the two side lock shafts 74510 and the round holes on both sides inside the guide groove 747, ensuring that the overall adjustable part 74 is in a stable state after the downward adjustment.
[0037] The above are only the preferred examples of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
