[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0027] like Figure 1-4 As shown, a non-powered roller conveyor with adjustable conveying direction includes a roller 1 with a rotating shaft 11 at both ends, and a bearing frame 2 fixedly connected to the rotating shaft 11. The bearing frame 2 is provided with screws 31 arranged opposite to each other and freely movable.
[0028] It also includes a threaded sleeve 4, which is used to thread a screw 31 on an adjacent rotating shaft 11.
[0029] Specifically, the bearing is installed in the bearing housing 2 using a gradient method, and the inner ring of the bearing and the gradient on the rotating shaft 11 are locked together. The connection method is existing technology and will not be described in detail here.
[0030] Furthermore, in the default state, the ends of the screw 31 are in contact with the ends of the adjacent screw 31. After rotating the screw sleeve 4, the two screws 31 are moved away from each other, and the outer wall of the screw sleeve 4 is provided with folds and recesses to increase friction.
[0031] By rotating the screw sleeve 4 to extend the screws 31 at both ends, the distance between the shafts 11 of two adjacent rollers 1 is increased. Similarly, the same method is used to adjust the distance to a greater extent on the other side of the roller 1 (or one end is kept still while the other end is adjusted to an appropriate distance). This process is repeated on other rollers 1, so that a fan-shaped area is gradually formed between adjacent rollers 1, thereby causing the conveyor line to bend in the conveying direction. This allows a single conveyor line to meet the requirement of redirecting the transport of items. The operation is manual, which not only achieves energy-saving effects but also provides long-term stability through the use of mechanical parts.
[0032] As a further embodiment of this utility model, a ball block 3 is fixedly installed at the end of the screw 31, and a ball hole 21 for fitting the ball block 3 is provided on the bearing bracket 2.
[0033] Specifically, the center of ball block 3 is located in bearing bracket 2 to ensure the stability of ball block 3 during rotation without it coming off.
[0034] The ball block 3 allows the screw 31 to move at any angle, enabling the ends of the screw 31 at both ends of the screw sleeve 4 to adapt to the fan-shaped position after the shaft 11 is adjusted, ensuring the formation of the conveyor line reversal. At the same time, the range of motion reached by the side wall of the screw 31 against the side wall of the bearing bracket 2 is greater than the fan-shaped adjustment required by the shaft 11.
[0035] As another embodiment further provided by this utility model, the bearing bracket 2 is split into two parts, and the ball hole 21 can be opened along with the bearing bracket 2.
[0036] Specifically, the ball hole 21 is divided into a hemisphere on the horizontal plane, so the ball hole 21 can ensure the sliding limit of the ball block 3 when it is closed.
[0037] By using a detachable bearing bracket 2 with bolts and nuts, the installation of the ball block 3 becomes more convenient, and the stability of the screw 31's movement is ensured after the bearing bracket 2 is installed.
[0038] As another embodiment of this utility model, a limiting arm 42 is also provided on the screw sleeve 4 and is inserted into the bearing bracket 2.
[0039] The symmetrically arranged limiting arms 42 are inserted and locked to the bearing bracket 2. On the one hand, this provides guidance for the two screws 31 to move away from each other. On the other hand, it can also release the lock, which facilitates the sliding adjustment of the bearing bracket 2 and the ball block 3.
[0040] As another embodiment provided in this utility model, a rotating ring 41 is rotatably provided on the screw sleeve 4, and the rotating ring 41 and the limiting arm 42 are fixedly connected.
[0041] Specifically, the limiting arm 42 and the rotating ring 41 are welded together, and the rotation method of the rotating ring 41 and the screw sleeve 4 is existing technology, which will not be described in detail here.
[0042] The rotating ring 41 ensures that the screw sleeve 4 is not disturbed by rotation during rotation, and also ensures the limiting function of the limiting arm 42.
[0043] As another embodiment of this utility model, the bearing bracket 2 is provided with equidistantly arranged locking holes 22, and the end of the limiting arm 42 is fixedly installed with a locking block 43 that is inserted and engaged with any of the locking holes 22.
[0044] Specifically, the lock hole 22 is located on the side wall of the bearing bracket 2 at the opening and closing position.
[0045] When the height of the bearing bracket 2 needs to be adjusted, the screw 31 deflects downward and adjusts the locking holes 22 on the bearing bracket 2 to engage with the locking block 43. The purpose is to use the limiting arm 42 to fix and limit the bearing bracket 2 after the height is adjusted.
[0046] As another embodiment provided in this utility model, a support column 23 is fixedly installed on the bearing bracket 2.
[0047] Specifically, the support column 23 is detachably connected to the bearing bracket 2 using bolts, nuts, and bearings.
[0048] The height of support column 23 can be adjusted by using an electric push rod or a staggered extension rod with multiple holes at the lower end and locking it with bolts and nuts to meet the on-site requirements for the height of the conveyor line.
[0049] As another embodiment further provided in this utility model, the limiting arm 42 is specifically a Z-shaped elastic metal rod.
[0050] Through the elastic metal rod and the pressure applied by its shape, the limiting arm 42 can maintain the pressure limiting effect on the bearing frame 2, preventing the locking function from loosening.
[0051] As another embodiment further provided in this utility model, the locking block 43 is specifically a rubber block.
[0052] The rubber locking block 43 can improve the friction to prevent slippage. At the same time, when the screw 31 deflects horizontally, the locking block 43 swings horizontally in the locking hole 22 and still maintains the locking effect. Meanwhile, after the screw sleeve 4 moves away, the elastic limiting arm 42 restores part of its deformation.
[0053] As another embodiment further provided in this utility model, the support 23 is specifically an alloy metal rod.
[0054] The alloy support pillars 23 ensure the pressure resistance during the conveying process, allowing the conveyor line to stably transport items under the action of multiple support pillars 23.
[0055] Working principle: By rotating the screw sleeve 4, the screws 31 at both ends are extended to increase the distance between the shafts 11 of two adjacent rollers 1. Similarly, the same method is used to adjust the distance to a larger size on the other side of the roller 1, and this step is performed on other rollers 1 in sequence, so that a fan-shaped area is gradually formed between adjacent rollers 1, thereby causing the conveyor line to bend in the conveying direction, so that a single conveyor line can meet the redirection of the transport of items.
[0056] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
