Description

Technical Field

[0001] The utility model relates to packaging production equipment, in particular to a quick rejecting device of a bottom pasting machine. Background Art

[0002] The bottom gluing machine is a special equipment used to seal the bottom of packaging bags. When working, the packaging bags are fed into the bottom gluing machine through the bag feeding assembly for bottom sealing. In the actual production process, the angle of the packaging bags may be skewed when they are fed in, resulting in the inability to maintain the required angle when feeding them into the bottom gluing station, which will affect the subsequent bottom sealing operation. Therefore, some mechanisms that can remove packaging bags have also appeared on the market, but they often have defects such as low detection accuracy and slow rejection speed, and the user experience is not good.

[0008] It further includes a second cylinder. The piston rod of the second cylinder is connected to one end of a first swing arm. The other end of the first swing arm is connected to a transmission shaft rotatably arranged on the frame. The transmission shaft is connected to one end of a second swing arm. The other end of the second swing arm is hinged to one end of a transmission arm. The other end of the transmission arm is hinged to a swing frame. A winding wheel is arranged on the swing frame. The rejection conveyor belt bypasses the winding wheel. By controlling the swing of the swing frame, the rejection conveyor belt can be made to approach or move away from the pressure conveyor belt.

[0009] For the quick rejection device of the bottom-pasting machine with the above technical solution, by arranging the in-place sensors, if all the in-place sensors detect the packaging bag simultaneously, it indicates that the packaging bag is fed at the required flush angle. If different in-place sensors do not detect the packaging bag simultaneously, it indicates that the angle of the packaging bag has tilted.

[0020] As shown in the figure, the rapid rejection device of the bottom pasting machine disclosed by the utility model includes arranged feeding conveyor belts 3, and a pressing conveyor belt 4 is arranged corresponding to each feeding conveyor belt 3. Furthermore, a pushing conveyor belt 5 is arranged corresponding to one side of the feeding conveyor belt 3, and pushing blocks 6 are arranged on the pushing conveyor belt 5 at intervals. The pushing blocks 6 can cooperate to push the packaging bags, so as to further improve the stability and accuracy of the packaging bag transportation. The packaging bags are tightly pressed between the feed conveyor belt 3 and the pressure conveyor belt 4 for transportation. A mounting frame is provided above the conveying path of the feed conveyor belt 3, and in-place sensors 7 are arranged on the mounting frame. In this embodiment, the in-place sensors 7 are photoelectric sensors. A large rotating wheel 15 is provided at the discharge end of the feed conveyor belt 3, and the pressure conveyor belt 4 bypasses the large rotating wheel 15, and also includes a rejection conveyor belt 2 and a rejection ejector rod 19. The rejection conveyor belt 2 is arranged corresponding to the pressure conveyor belt 4 bypassing the large rotating wheel 15, and a discharge platform 17 is provided corresponding to the discharge end of the feed conveyor belt 3. A clearance hole 16 is provided on the discharge platform 17, and the rejection ejector rod 19 is connected to the mobile drive component, and the mobile drive component can drive the rejection ejector rod 19 to be ejected from the clearance hole 16, and the bag body that does not meet the requirements is pushed into between the rejection conveyor belt 2 and the pressure conveyor belt 4 for transportation, and a collecting bucket 1 is provided at the discharge end of the rejection conveyor belt 2 and the pressure conveyor belt 4. Specifically, the mobile driving assembly is a first cylinder 18, the piston rod of the first cylinder 18 is connected to the rejection push rod 19, and the rejection push rod 19 can be driven to extend and retract by controlling the action of the first cylinder 18. In addition, it also includes a second cylinder 8, the piston rod of the second cylinder 8 is connected to one end of the first swing arm 9, the other end of the first swing arm 9 is connected to a transmission shaft 10 rotatably arranged on the frame, the transmission shaft 10 is connected to one end of the second swing arm 11, the other end of the second swing arm 11 is hinged to one end of the transmission arm 12, the other end of the transmission arm 12 is hinged to the swing frame 13, the swing frame 13 is provided with a winding wheel 14, the rejection conveyor belt 2 bypasses the winding wheel 14, and the rejection conveyor belt 2 can be made close to the pressing conveyor belt 4, or away from the pressing conveyor belt 4 by controlling the swing frame 13 to swing. The swing of the swing frame 13 is achieved by the action of the second cylinder 8 and the transmission through the swing arm and the transmission arm. During assembly and conveyor belt winding, the swing frame 13 can be controlled to swing to an angle where the reject conveyor belt 2 and the pressing conveyor belt 4 are far apart, which is convenient for conveyor belt winding and overall assembly of the equipment. When in use, the swing frame 13 is controlled to swing to an angle where the reject conveyor belt 2 is close to the pressing conveyor belt 4. At the same time, it is also convenient to realize the separate maintenance of components.

[0021] The working principle of the present utility model is as follows: The packaging bag is first conveyed backward by the feeding conveyor belt 3 and the material pressing conveyor belt 4. When it is conveyed near the discharging end, the packaging bag will pass through the arranged in-place sensors 7. If all the in-place sensors 7 simultaneously sense the packaging bag, it indicates that the packaging bag is fed at the required angle. Finally, the packaging bag will be sent out from the discharging platform 17 and enter the bottom pasting station for bottom pasting processing. If all the in-place sensors 7 do not simultaneously detect the packaging bag, it indicates that the angle of the packaging bag is inclined. At this time, the rejection ejector rod 19 is controlled to extend, and the packaging bag sent out from the discharging ends of the feeding conveyor belt 3 and the material pressing conveyor belt 4 is pushed into the space between the rejection conveyor belt 2 and the material pressing conveyor belt 4, and is conveyed to the collection hopper 1 under the combined conveyance of the rejection conveyor belt 2 and the material pressing conveyor belt 4. This rejection method enables the packaging bag to be rejected during the conveying process, without the need to stop the machine and wait, and will not affect the subsequent conveyance of the packaging bags. Then, the worker can take away the packaging bags in the collection and feed them again.

[0022] With this structure of the present utility model, by arranging the in-place sensors, if all the in-place sensors simultaneously detect the packaging bag, it indicates that the packaging bag is fed at the required flush angle. If different in-place sensors do not simultaneously detect the packaging bag, it indicates that the angle of the packaging bag is inclined. The detection accuracy is very high, and the subsequent rejection operation can be realized by transferring and rejecting during the conveying process of the packaging bag. The rejection speed is fast and will not affect the subsequent continuous conveyance of the packaging bags.
