Description

Technical Field

[0001] This utility model relates to the field of cardboard processing technology, specifically to a cardboard feeding and paperboard positioning and adjustment device for cardboard processing. Background Technology

[0002] Cardboard boxes are usually made of multiple cardboard sheets joined together. In the cardboard box production process, in order to improve the quality of the cardboard boxes, multiple layers of cardboard are often glued together to form thicker cardboard sheets. These thicker cardboard sheets are then folded into cardboard boxes. In order to make the multiple layers of cardboard sheets tightly glued together, the multi-layer cardboard sheets coated with adhesive are fed into the gluing mechanism by a conveyor belt for pressing. However, the cardboard sheets are prone to shifting in position when transported on the conveyor belt, which can cause them to collide with the entrance of the gluing mechanism when they arrive at the gluing mechanism, thus damaging the cardboard sheets. Utility Model Content

[0003] The purpose of this invention is to provide a paperboard positioning and adjustment device for carton processing, so as to solve the problems mentioned in the background art.

[0005] Preferably, the adjustment assembly includes a motor, a bidirectional threaded rod, two first sliders, and a sliding rod. The motor is fixedly connected to the front side of the first fixed frame. The motor output shaft passes through the first fixed frame and is fixedly connected to the bidirectional threaded rod. The rear end of the bidirectional threaded rod is rotatably connected to the left end of the rear side wall of the first fixed frame. The threads at both ends of the bidirectional threaded rod have opposite directions. The two first sliders are threadedly connected to the two ends of the bidirectional threaded rod. The ends of the two first sliders away from the bidirectional threaded rod are slidably connected to the sliding rod. The two ends of the sliding rod are fixedly connected to the inner side wall of the first fixed frame. The two first mounting brackets are fixedly connected to the bottom surface of the two first sliders.

[0006] Preferably, the sliding assembly includes a second fixed frame, two slide grooves and two second sliders. The second fixed frame is fixedly connected to the left end of the top surface of the frame. The two slide grooves are distributed vertically on the side of the second fixed frame. The two second sliders are slidably disposed inside the two slide grooves. The side of the two second sliders away from the second fixed frame is fixedly connected to the side of the second mounting frame.

[0007] Preferably, the centering assembly includes an electric telescopic rod, a pressure sensor, and a push plate. The electric telescopic rod is fixedly connected to the middle of the side of the third mounting frame. The telescopic end of the electric telescopic rod passes through the third mounting frame and is fixedly connected to the pressure sensor. The push plate is fixedly connected to the side of the pressure sensor away from the electric telescopic rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. In use, the first mounting frame, the connecting frame, and the multiple guide rollers inside the second mounting frame guide the cardboard on the conveying mechanism. The motor drives the bidirectional threaded rod to rotate, which causes the bidirectional threaded rod to drive the two first sliders to move closer to each other. The two first sliders then drive the first mounting frame to move closer to each other, thus making it suitable for guiding cardboard of different sizes. 2. When this utility model is in use, the electric telescopic rod drives the push plate to extend, and the two push plates push the cardboard to the middle position, thereby completing the positioning adjustment of the cardboard. The pressure sensor monitors the clamping force of the push plate to avoid excessive pressure that could damage the cardboard. Attached Figure Description

The rear end of the bidirectional threaded rod 42 is rotatably mounted on the left end of the rear side wall of the first fixed frame 3 via a bearing. The threads at both ends of the bidirectional threaded rod 42 have opposite directions. The two first sliders 43 are threaded to both ends of the bidirectional threaded rod 42. The slide rod 44 is slidably connected to the end of the two first sliders 43 away from the bidirectional threaded rod 42. The two ends of the slide rod 44 are bolted to the inner side wall of the first fixed frame 3. The two first mounting brackets 5 are bolted to the bottom surface of the two first sliders 43.

[0016] The sliding assembly 8 includes a second fixed frame 81, two slide grooves 82 and two second sliders 83. The second fixed frame 81 is bolted to the left end of the top surface of the frame 1. The two slide grooves 82 are distributed vertically and opened on the side of the second fixed frame 81. The two second sliders 83 are slidably installed inside the two slide grooves 82. The side of the two second sliders 83 away from the second fixed frame 81 is bolted to the side of the second mounting frame 7.

[0017] The centering assembly 10 includes an electric telescopic rod 101, a pressure sensor 102, and a push plate 103. The electric telescopic rod 101 is bolted to the middle of the side of the third mounting bracket 9. The telescopic end of the electric telescopic rod 101 passes through the third mounting bracket 9 and is threadedly connected to the pressure sensor 102. The push plate 103 is bolted to the side of the pressure sensor 102 away from the electric telescopic rod 101. The photoelectric sensor 104 is bolted to the right end of the side of the push plate 103. The front end of the photoelectric sensor 104 passes through the push plate 103.

[0018] Multiple guide rollers 11 are rotatably mounted on the inner sides of the first mounting frame 5, the connecting frame 6, and the second mounting frame 7 via bearings.

[0019] The support frame 12 is bolted to the corner of the bottom surface of the frame 1. The control panel 13 is bolted to the middle of the front side of the frame 1.

[0020] Working principle: In use, multiple guide rollers 11 on the inner sides of the first mounting frame 5, connecting frame 6, and second mounting frame 7 guide the cardboard on the conveying mechanism 2. The motor 41 is started, driving the bidirectional threaded rod 42 to rotate. This causes the bidirectional threaded rod 42 to move the two first sliders 43 closer together, which in turn move the first mounting frame 5 closer together, thus adapting to guide cardboard of different sizes. After the photoelectric sensor 104 detects that the cardboard has moved to the designated position, the control panel 13 controls the conveying mechanism 2 to stop conveying. The electric telescopic rod 101 drives the push plate 103 to extend, and the two push plates 103 push the cardboard to the middle position, thus completing the positioning adjustment of the cardboard. The pressure sensor 103 monitors the clamping force of the push plate 104. When the pressure reaches a certain value, it transmits a signal to the control panel 13, which then controls the electric telescopic rod 101 to retract, preventing excessive pressure from damaging the cardboard. This invention has the advantages of being easy to use and having good performance.
