Description

Technical Field

[0001] The utility model relates to the technical field of bag intercepting machines, in particular to an automatic bag intercepting machine. Background Art

[0002] There are mainly the following types of steering operation modes for bagged items transported by traditional belt conveyors: baffle type: manual switching after stopping the machine is required, which is inefficient, and the baffle is made of metal, which can easily scratch the packaging bags, causing the materials to scatter and require manual cleaning; baffle type steering is achieved through the inertia of the bagged items. When multiple bags reach the steering position at the same time, it is easy to cause bag jams. In severe cases, the blockage will cause shutdown and seriously affect production; pure manual type: when the conveyor line cannot be stopped for switching and the bagged items need to be turned, the bagged items running in a straight line are directly moved and turned manually. This method has high labor intensity and has great safety hazards. To this end, we propose an automatic bag intercepting machine to solve the above problems. Utility Model Content

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] Example

[0017] See also Figure 1-2The utility model provides a technical solution: an automatic bag intercepting machine, including a crossbeam 1, the left side of the crossbeam 1 is rotatably mounted on the frame 4 through a rotating pin 3, the top of the crossbeam 1 is fixedly connected to the reducer 2, the front side of the crossbeam 1 is fixedly connected to the main motor 9, the output shaft end of the main motor 9 is connected to the input shaft of the reducer 2, the right side of the frame 4 is rotatably connected to an electric push rod 5, the output end of the electric push rod 5 is rotatably connected to the front of the crossbeam 1, the bottom of the crossbeam 1 is rotatably mounted with an active roller 6, the output end of the reducer 2 is fixedly connected to the top of the active roller 6, so that the angle of steering of the bagged items can be freely adjusted within a certain range without stopping the machine. The steering of the bagged items relies on inertia and the traction force of the endless belt 8 to achieve, making the steering more reliable and smooth. Even if multiple bags arrive at the steering position at the same time, they can pass smoothly. The electric push rod 5 is arranged without crossing the belt conveyor, and the belt conveyor will not be stuck due to temporary stacking of bags. The endless belt 8 adopts a polyester herringbone pattern belt, which is durable and has strong friction and traction.

[0018] In this embodiment, specifically: a driven roller 7 is rotatably mounted on the bottom of the crossbeam 1, and the driving roller 6 and the driven roller 7 are connected to each other via an endless belt 8;

[0019] In this embodiment, specifically: the top of the driven roller 7 is rotatably connected to a connecting seat, and the crossbeam 1 is slidably sleeved on the outside of the connecting seat;

[0020] In this embodiment, specifically: the right side of the connecting seat is fixedly connected to the adjusting screw rod 10, and the outer side of the adjusting screw rod 10 is threadedly connected to a nut;

[0021] In this embodiment, specifically: the crossbeam 1 is rotatably sleeved on the outside of the nut;

[0022] In this embodiment, specifically: a control box 11 is provided above the beam 1;

[0023] In this embodiment, specifically, the control box 11 is electrically connected to the main motor 9 through a conductive wire.

[0024] The utility model is in operation: when the bagged articles conveyed by the belt conveyor need to be turned, the control box 11 is operated to start the main motor 9 (it can also be started on site), the main motor 9 rotates and drives the active roller 6 to rotate through the reducer 2, driving the endless belt 8 and the driven roller 7 to rotate, and the electric push rod 5 is started (it can also be started on site), pushing the crossbeam 1 to rotate, so that the crossbeam 1 and the belt conveyor reach the required angle ( Figure 2 After the angle β is reached, the electric push rod 5 stops working (the main motor 9 continues to run). When the bagged items running in a straight line touch the rotating endless belt 8, they change their running direction under the inertia and the traction of the rotating endless belt 8, enter the chute, and then enter other belt conveyor systems through the chute, completing the turning operation of the bagged items.

[0025] When the bagged items transported by the belt conveyor need to run in a straight line, the control box 11 operates the electric push rod 5 to retract (it can also be operated on site), and the electric push rod 5 retracts and drives the crossbeam 1 to rotate to the return position (the main motor 9 continues to run during the retraction of the electric push rod 5), the electric push rod 5 stops running and the main motor 9 stops running, and the bagged items run in a straight line.

[0026] When the endless belt 8 is found to be too tight, too loose, or deviating up or down, the nut can be rotated to drive the adjusting screw 10 to move laterally, the adjusting screw 10 drives the connecting seat to move laterally, and the connecting seat drives the driven roller 7 to move laterally. During the movement, the driven roller 7 tightens the endless belt 8 for adjustment. When the angle of the bagged items turning to run ( Figure 2 When the angle α in the middle does not reach the required angle, the angle between the beam 1 and the belt conveyor can be adjusted by adjusting the stroke of the electric push rod 5 ( Figure 2 The angle β in the figure is adjusted to achieve the required angle for the steering of the bagged items, thereby forming an automatic bag intercepting machine. The steering angle of the bagged items can be freely adjusted within a certain range without stopping the machine. The steering of the bagged items is achieved by both inertia and the traction of the endless belt 8, making the steering more reliable and smooth. Even if multiple bags arrive at the steering position at the same time, they can pass smoothly. The electric push rod 5 is arranged not to cross the belt conveyor, and the belt conveyor will not be stuck due to temporary bag overlap. The endless belt 8 adopts a polyester herringbone pattern belt, which is durable and has strong friction and traction.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
