Description

Technical Field

[0001] The utility model relates to the field of packaging machines, in particular to a bag outlet steering adjustment device for a mobile packaging machine. Background Art

[0002] A packaging machine is a type of mechanical equipment that packages products, and its main function is to protect the products and enhance their appearance. A mobile packaging machine is a special type of packaging machine that is mobile and can be quickly transported to where it is needed.

[0003] Due to design reasons, the output end of the mobile packaging machine is driven by the conveyor belt of the outlet conveyor and the movable conveyor perpendicular to its horizontal direction and guided by the steering roller on the side. The bags of the packaging machine are often blocked at the outlet steering position. Therefore, the outlet of the mobile packaging machine now uses a curved conveyor for steering.

[0004] Existing mobile packaging machines generally transport packaging bags to the surface of a curved conveyor and then to a palletizer for palletizing. During production and observation, it was found that there was a height difference at the connection between the curved conveyor and the palletizer, which would reduce the stability of the device in transporting packaging bags.

[0005] Therefore, in order to solve the above problems, a bag outlet steering adjustment device for a mobile packaging machine is proposed. Utility Model Content

[0033] Working principle: dock the end of the curved conveyor 1 away from the first connecting plate 12 with the output end of the mobile packaging machine, dock the end of the curved conveyor 1 close to the first connecting plate 12 with the palletizer and start the electric push rod 14. After the electric push rod 14 is started, the angle of the connecting rod 15 will change, and the connecting rod 15 will transmit the pressure applied by the electric push rod 14 to the first connecting plate 12 so that the angle of the first connecting plate 12 will also change. At this time, the first connecting plate 12 will rotate with the roller 13 and the height of the first connecting plate 12 from the ground will also change. After adjusting the height of the first connecting plate 12 to the input end of the palletizer, the device can be started, and then the packaging bags will flow out from the output end of the packaging machine. The bag is then transported to the surface of the roller 13 along the curved conveyor 1 and is then transported to the palletizer along the roller 13 and is then palletized. When the bag reaches the surface of the roller 13, it comes into contact with the pressing plate 23. The pressing plate 23 compresses the spring telescopic rod 22 under the squeezing action of the bag. Then, the pressing plate 23 moves toward the vertical plate 2 along with the spring telescopic rod 22. The spring telescopic rod 22 applies elastic force to the pressing plate 23 so that the pressing plate 23 squeezes the bag. When the bag slides along the surface of the pressing plate 23, it moves toward the middle of the roller 13 under the elastic force of the spring telescopic rod 22. When the package bag comes into contact with the pressure plate 23, it will also come into contact with the runner 3. The runner 3 will rotate under the action of friction. The runner 3 will convert the sliding friction between the packaging bag and the pressure plate 23 into rolling friction, reducing the friction between the packaging bag and the pressure plate 23, and reducing the wear or damage caused by friction when the packaging bag moves. At the same time, the runner 3 will also press the side wall of the packaging bag to reduce wrinkles on the surface of the packaging bag; when the packaging bag is transported, it will collide with the runner 3, and the buffer pad 4 will come into contact with the packaging bag before the runner 3. After being squeezed by the packaging bag, the buffer pad 4 will deform and absorb the impact, and then the buffer pad 4 will transmit the attenuated impact force to the runner 3 and the pressure plate 23. Plate 23; when the packaging bag moves along the surface of the pressure plate 23, the packaging bag will come into contact with the brush bristles 52, and the brush bristles 52 will clean the surface of the packaging bag to reduce the dust attached to the surface of the packaging bag; when working, the air intake pipe 6 can be connected to an air pump, and the air pump will inject air into the interior of the air intake pipe 6, and the air flow will pass through the air intake pipe 6 and the first connecting plate 12 into the interior of the roller 13, and then the air flow will be ejected from the circular hole 62 and reach the surface of the packaging bag. The packaging bag will float slightly under the action of the air flow, thereby improving the corrective effect of the pressure plate 23 on the packaging bag; when the device is placed, debris, dust and other impurities will diffuse through the air to the circular hole 62, and the baffle 7 will intercept these impurities.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
