Description

Technical Field

[0001] The utility model relates to the technical field of narrowband machines, in particular to a narrowband machine with an anti-deviation function. Background Art

[0002] Narrow-band machines are important equipment for logistics sorting, and are mainly used as converging machines (also called merging machines) and diverting machines. Existing narrow-band machines all drive the conveyor belt (belt) to move through a transmission roller. Since the transmission roller can only transmit torque and bear the force of the conveyor belt, the narrow-band machine will frequently cause the conveyor belt to deviate during the logistics sorting process. In order to prevent the conveyor belt from deviating and maintain the continuity of the logistics sorting operation, an adjustment roller and a tensioning roller are installed between the active roller and the driven roller. For example, the patent document with announcement number CN104003175B discloses a 45-degree narrow-band converging machine for logistics automation conveyor lines.

[0003] In actual production activities, adding deviation adjustment rollers and tensioning rollers to prevent the narrow-band conveyor from conveyor belt deviation will not only lead to complex structure and high production costs of the narrow-band conveyor, but also increase the size and weight of the entire narrow-band conveyor, which is not conducive to the installation of the narrow-band conveyor in the logistics sorting workshop.

[0004] Therefore, how to prevent the conveyor belt of a narrow belt conveyor from deviation without increasing the volume has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0040] Examples, such as Figure 1-Figure 4 As shown, a narrowband machine with an anti-deviation function comprises:

[0041] Frame 10.

[0042] The active roller 20 is installed at one end of the frame 10 in the transverse direction, and a plurality of active rollers 20 are sequentially arranged and fixedly connected along the longitudinal direction.

[0043] The driven roller 30 is multiple in number and the multiple driven rollers 30 are installed at the other end of the frame 10 in the transverse direction.

[0044] The conveyor belt 40 is provided in a plurality, and the plurality of conveyor belts 40 are installed between the driving roller 20 and the driven roller 30 in a one-to-one correspondence.

[0045] The driving motor 50 is installed on one longitudinal side of the frame 10 , and the driving motor 50 is transmission-connected with the active roller 20 to drive the active roller 20 to drive the conveyor belt 40 to move.

[0046] In the longitudinal direction, the radial dimensions of the active roller 20 and the driven roller 30 increase first and then decrease.

[0047] The present application adopts a split structure, in which a plurality of active rollers 20 are linearly arranged along the longitudinal direction at one lateral end of the frame 10, and a plurality of driven rollers 30 are installed at the other lateral end of the frame 10, and in the longitudinal direction, the radial dimensions of the active rollers 20 and the driven rollers 30 first increase and then decrease, so that when the conveyor belt 40 deviates to one side of the active roller 20 or the driven roller 30, the active roller 20 or the driven roller 30 can generate an axial force on the conveyor belt 40, thereby realizing automatic deviation correction of the conveyor belt 40, preventing the conveyor belt 40 from deviating, and making the narrow-band machine have a smaller volume, which is conducive to the installation of the narrow-band machine in the logistics sorting workshop.

[0048] It should be noted that the horizontal direction in this application refers to Figure 1 The double arrow direction in the application refers to the vertical relationship Figure 1 The single room head direction.

[0049] In a specific embodiment, if Figure 2 , Figure 3 As shown, the lateral distance between the driven roller 30 and the active roller 20 is adjustable, so that the staff can tighten the conveyor belt 40.

[0050] Preferably, Figure 2 , Figure 3 As shown, a mounting plate 16 is fixedly connected to the other lateral end of the frame 10. The mounting plates 16 are arranged in pairs at the other lateral end of the frame 10, and a lateral slide groove 17 is opened on the mounting plate 16. The lateral slide groove 17 makes the mounting plate 16 as a whole U-shaped with an open right end.

[0051] The driven roller 30 is rotatably mounted on the central shaft 31, which is arranged in the longitudinal direction, and the two ends of the central shaft 31 are laterally slidably connected in the transverse slide groove 17; radial adjustment holes are provided at the two ends of the central shaft 31, and a tightening screw 60 is threadedly connected in the radial adjustment hole, and one transverse end of the tightening screw 60 abuts against the mounting plate 16, that is, one transverse end of the tightening screw 60 abuts against the bottom wall of the transverse slide groove 17, so that the driven roller 30 is driven to move in the transverse direction by screwing the tightening screws 60 at both ends of the driven roller 30, thereby realizing the tightening of the conveyor belt 40; at the same time, the conveyor belt 40 can also be corrected by screwing the tightening screw 60 at one end of the driven roller 30.

[0052] It should be noted that the transverse sliding connection between the central shaft 31 and the transverse sliding groove 17 belongs to the prior art, for example, a plane that fits with the groove side wall is machined on the central shaft 31.

[0053] In a specific embodiment, if Figure 1 , Figure 2 As shown, along the longitudinal direction, the transverse dimensions of the plurality of conveyor belts 40 gradually increase so that the narrow belt machine can be used as a converging machine or a diverting machine.

[0054] Preferably, Figure 3 , Figure 4As shown, the frame 10 is arranged in the horizontal direction, and the frame 10 is in a trapezoidal shape as a whole. The frame 10 includes an upper frame 11, a long side plate 12, a short side plate 13, a transition plate 14 and a lower frame 15; wherein the upper frame 11 and the lower frame 15 are arranged in parallel one above the other, that is, the upper frame 11 is arranged directly above the lower frame 15; a mounting step is provided at the other end of the upper frame 11 in the horizontal direction, and the driven roller 30 and the transition plate 14 are installed on the mounting step, that is, the inclined side of the trapezoidal frame 10 is provided with a step-by-step decreasing mounting step, and the driven roller 30 and the transition plate 14 are installed on the mounting step, and the driving roller 20 is installed on the right-angle side of the trapezoidal frame 10.

[0055] One longitudinal end of the upper frame 11 is fixedly connected to the lower frame 15 through a long side plate 12, that is, the bottom side of the trapezoidal frame 10 is provided with a long side plate 12, and the long side plate 12 is fixedly connected to the upper frame 11 and the lower frame 15; the other longitudinal end of the upper frame 11 is fixedly connected to the lower frame 15 through a short side plate 13, that is, the top side of the trapezoidal frame 10 is provided with a short side plate 13, and the short side plate 13 is fixedly connected to the upper frame 11 and the lower frame 15.

[0056] More preferably, Figure 1 As shown, a mounting frame 18 is fixedly connected to a side of the long side plate 12 away from the upper frame body 11 , and a transmission mechanism 70 is installed on the mounting frame 18 . The transmission mechanism 70 is transmission-connected between the driving motor 50 and the active roller 20 .

[0057] In a specific embodiment, the active roller 20 is a drum-shaped roller or a conical roller; the driven roller 30 is a drum-shaped roller or a conical roller.

[0058] This setting is because: for the drum roller, when the conveyor belt is tightened, the force generated between the drum roller and the conveyor belt and the friction generated during operation are no longer evenly distributed. The part with the greatest force is the highest point of the drum surface, and the force on the rest of the drum surface will decrease as the curvature decreases, showing a decreasing state. Due to the change in the force condition, there will be no relative offset between the drum surface of the drum roller and the conveyor belt, thereby achieving the effect of automatic correction.

[0059] For the conical roller, when the conveyor belt deviates to the inclined surface of the conical roller, the conical bodies at both ends of the conical roller will form a resistance, thereby generating a lateral thrust, automatically moving the conveyor belt to the center position, achieving the effect of automatic deviation correction.

[0060] Compared with the prior art, this application has at least the following beneficial technical effects:

[0061] The narrow-band machine of the present application adopts two sets of rollers to drive the conveyor belt to move, which can greatly reduce the height and volume of the narrow-band machine and improve space utilization. It is not only suitable for sorting environments in various occasions of diversion and convergence, but also suitable for double-layer or multi-layer conveyor lines.

[0062] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
