Description

Technical Field

[0001] This utility model belongs to the field of cardboard processing, and in particular relates to a cardboard feeding device. Background Technology

[0002] As is well known, cardboard, also known as pulp molding, is made from cardboard scraps, newsprint, white pure wood pulp, etc. The pulp is crushed and mixed to a certain concentration, then vacuum-formed using customized CNC molds based on product design. After drying, it forms various types of environmentally friendly paper products for different uses. During cardboard processing, the cardboard to be processed needs to be fed to the next processing station using a feeding device.

[0003] There are various types of cardboard feeding devices available. One type features two traction wheels on a machine base, with a gap between them. The gap size matches the thickness of the cardboard to be fed. A traction motor drives the lower traction wheel. A conveyor is located at the front of the machine base, directly opposite the traction wheels. When feeding cardboard, a suction cup holds the cardboard, and the front end of the cardboard is inserted into the gap between the traction wheels. The suction cup detaches from the cardboard, and the traction motor drives the lower traction wheel to rotate. Driven by the two traction wheels, the cardboard moves forward onto the conveyor, which then transports it to the next processing position. While this method achieves cardboard feeding, the inability to adjust the gap between the two traction wheels means it cannot adapt to different cardboard thicknesses. Furthermore, this feeding device can only feed cardboard of the same thickness, resulting in poor adaptability. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a cardboard feeding device, which aims to solve the problem that the existing cardboard feeding devices can only feed cardboard of the same thickness and have poor adaptability.

[0020] When the device is used to feed the paperboards one by one and in order to the next station for processing, first, the paperboards are placed on the lifting plate according to the requirements, then the material taking mechanism sends the paperboards to the traction mechanism according to the order, the paperboards are sent to the feeding conveying table by the traction mechanism, and the feeding conveying table sends the paperboards to the next station.

[0021] In the structure, the pressure wheels are located directly above the traction wheels. The front ends of the pressure wheels have a gap with the front ends of the traction wheels. When the material taking mechanism takes a paperboard and moves towards the traction wheel, after the front end of the paperboard is inserted into the gap between the pressure wheel and the traction wheel, the material taking mechanism immediately separates from the paperboard. The traction wheel drives the paperboard to move forward, the paperboard is sent to the feeding conveying table, and the feeding conveying table sends the paperboard to the next station. After the material taking mechanism separates from the paperboard, the material taking mechanism takes the next paperboard and prepares to send it to the traction mechanism.

In the actual process of feeding the paperboard, the spring can keep the pressing wheel always slightly pressed on the paperboard, so that the paperboard cannot deviate during conveying and can be accurately fed to the feeding conveying table. At the same time, the pressing wheel and the traction wheel can adapt to paperboards of different thicknesses and can pull the paperboards of different thicknesses forward, thereby improving the adaptability of the whole device.

[0023] In the device, Figure 4 The feeding mechanism comprises a top beam 13 vertically slidingly installed in the rack 1, and the top beam 13 is slidingly provided with a feeding plate 14 in front and back, the feeding plate 14 is downwardly provided with a group of suction cups 15, the top beam 13 is provided with a moving air cylinder 151, the driving shaft of the moving air cylinder 151 is connected with the feeding plate 14, and the top of the rack 1 is downwardly provided with an up-down air cylinder 16 for driving the top beam 13 to slide up and down.

Then, the feeding plate moves upward, at this time, the front end of the paperboard is aligned with the gap between the pressing wheel and the traction wheel. The moving air cylinder drives the feeding plate to move forward, and when the front end of the paperboard penetrates into the gap, the suction cups immediately separate from the paperboard. Finally, the traction motor drives the traction wheel to rotate, and the traction wheel drives the paperboard to move forward until the paperboard is fed to the feeding conveying table.
