A second transmission part 4, the second transmission part 4 including a driving pulley 41 and a driven pulley 42; the driving pulley 41 and the driven sprocket 22 are axially integrally formed as a chain pulley; the driving pulley 41 is in transmission connection with the driven pulley 42 through a transmission belt 411; the driven pulley 42 is rotatably mounted on the second rotating shaft support 30b, the second rotating shaft support 30b is arranged on the second support 43, and the second support 43 is arranged on the bottom plate 121; the second bracket 43 is parallel to the first bracket 23.
The invention drives the first transmission part 2 to carry out chain transmission through the driving part 1, and then drives the second transmission part 4 to carry out belt transmission through the first transmission part 2; the driven chain wheel 22 of the first transmission part 2 and the driving belt wheel 41 of the second transmission part 4 are integrally formed, so that unnecessary connection of the second transmission part 4 between the first transmission parts 2 is reduced, and the width of the whole transmission assembly is reduced; and the first bracket 23 and the second bracket 43 are made parallel, so that the width of the whole transmission assembly is consistent.
To support the second transmission part 4 and the driven sprocket 22; the driven sprocket 22 is supported by the first bracket 23, and the second transmission part 4 is supported by the second bracket 43; the first bracket 23 and the second bracket 43 each include two vertically moving legs 231 and a fixed panel 232; two ends of the fixed panel 232 are respectively connected with a vertical moving support leg 231, and the fixed panel 232 is effectively supported by the vertical moving support legs 231 arranged at the two ends and leaves the bottom plate 121; so that both the chain drive fixed to the first bracket 23 and the second transmission 4 fixed to the second bracket 43 are at a distance from the bottom plate 121.
In order to be able to make certain adjustments to the height of the first bracket 23 and the second bracket 43; specifically, as shown in fig. 6, the vertical moving leg 231 includes an L-shaped piece 231a and an adjusting piece 231 b; the horizontal panel of the L-shaped member 231a abuts the bottom plate 121; a vertical panel of the L-shaped member 231a is provided with a long limiting hole 231 c; the vertical panel of the adjusting member 231b is fixed to the limiting hole 231c by a bolt, and specifically, the adjusting member 231b is provided with a bolt hole through which a bolt penetrates, and the bolt penetrates through the limiting hole 231c, so that the adjusting member 231b can be effectively fixed to the L-shaped member 231 a; because the limiting hole 231c is long-strip-shaped, the bolt can be adjusted up and down in the limiting hole 231 c; thus, when the adjusting member 231b needs to be adjusted upward, only the position of the bolt needs to be adjusted upward, so that the connected adjusting member 231b is finely adjusted to move upward.
In order to better fix the adjusting member 231b to the fixing panel 232, as shown in fig. 6, an upper mounting plate 2311 is provided on the vertical panel of the adjusting member 231b, so that the lower end surfaces of the upper mounting plate 2311 and the fixing panel 232 are attached to each other; and penetrates the upper mounting plate 2311 and the fixing panel 232 by bolts, so that the upper mounting plate 2311 and the fixing panel 232 are fixed.

In order to engage the V-belt 412, the driving pulley 41 and the driven pulley 42 are provided with corresponding V-grooves, thereby increasing the contact surface between the V-belt 412 and the pulleys.
In order to prevent the belt 411 from being loosened and the dragging of the belt 411 caused by the excessively long distance between the driving pulley 41 and the driven pulley 42, an auxiliary pulley assembly 233 is provided for supporting the belt 411; specifically, as shown in fig. 9 or 10, the auxiliary pulley assembly 233 includes a plurality of rotating wheels 233a and an elongated fixing member 233 b; the fixing member 233b is provided to the first bracket 23 or the second bracket 43, and each fixing member 233b is provided with a plurality of runners 233a along a length direction thereof; so that each runner 233a is positioned in the driving belt 411 and can be pressed against the driving belt 411 to prevent the driving belt 411 from being dragged and loosened, thereby improving the efficiency and reliability of the driving.
In order to enable the motor bracket 12 to be displaced on the base plate 121 in the chain drive direction, so that the tensioning of the chain drive is adjusted; the motor bracket 12 includes two fixing plates 122 and a base 123; the two fixing plates 122 are fixed to the bottom plate 121, and the base 123 is located between the two fixing plates 122; two sides of the base 123 are respectively connected with the fixing plate 122 through an adjusting bolt 124; as shown in fig. 8, connecting plates for fixing are disposed on two sides of the base 123, each connecting plate is provided with a plurality of limiting holes 123a, and bolts are disposed in the limiting holes 123a to fix the connecting plates to the bottom plate 121; because the limiting hole 123a is long-strip-shaped, and the length thereof is extended along the length direction of the first bracket 23; the position of the motor bracket 12 is moved in the direction of the first bracket 23 by adjusting the adjusting bolt 124, so that fine adjustment of the position of the motor 11 is completed. Specifically, the bolt of the limit hole 123a is loosened, the user rotates the adjusting bolt 124 to move the motor bracket 12, and then the bolt of the limit hole 123a is locked.
In order to allow the sprocket to move in the longitudinal direction of the first bracket 23, and/or the driven pulley 42 to move in the longitudinal direction of the second bracket 43; as shown in fig. 3, the first rotating shaft bracket 30a or the second rotating shaft bracket 30b is now provided to include a shaft fixing seat 31 and a fixing block 32; the first bracket 23 and/or the second bracket 43 are provided with strip-shaped through holes along the length direction thereof; fixed block 32 is fixed in the one side of through-hole, and axle fixing base 31 is equipped with the installation axle that is used for connecting sprocket wheel or driven pulley 42, and bolt 311 fixed connection is passed through in one side of axle fixing base 31 in fixed block 32.
In a preferred embodiment, a centering roller machine is based on the principle that two oppositely and obliquely driven conveyors are arranged, so that the objects on the two conveyors are kept centered in the conveying process; since the width of each transfer is set to be limited, the above-described transfer assembly can be adopted for the transfer section of the center-roller machine.
In summary, the driving portion 1 drives the first transmission portion 2 to perform chain transmission, and then the first transmission portion 2 drives the second transmission portion 4 to perform belt transmission; the conveying is carried out through belt transmission, so that the width of rollers is reduced; in addition, the position of the driving pulley, the driven pulley, the driving chain wheel and the driven chain can be adjusted through the arranged rotating shaft bracket 3, so that the tightness of the conveying belt 411 or the chain 211 can be adjusted; in addition, the present invention can be applied to the height of the first bracket 23 and the second bracket 43 by vertically moving the leg 231.
Therefore, the invention effectively overcomes various defects in the prior art and has high industrial utilization value.
The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
