Abstract
Description
Technical Field
[0001] The utility model relates to an improvement on a corrugated paper forming structure, in particular to a corrugated roller assembly for producing coreless corrugated paper. Background Art
[0002] Corrugated paper is a paper structure with corrugated waveforms, which is mainly used as a supporting layer in a cardboard structure. It improves the strength of the cardboard without increasing its weight. Usually, a cardboard structure with more than two layers of corrugated paper has core paper between the corrugated paper layers, and the core paper and the corrugated paper layers are bonded to form the main inner layer structure of the cardboard. With the development of production technology, a coreless corrugated cardboard structure has emerged, that is, no core paper is required, and the relatively raised peaks between the corrugated structures of the corrugated layers are aligned with each other and bonded to form a stable inner layer structure. Therefore, according to the production needs of the structure, the structure of the corrugated roller assembly needs to be improved accordingly. Utility Model Content
[0003] The purpose of the utility model is to overcome the above-mentioned shortcomings in the prior art and to provide a corrugated roller assembly for producing coreless corrugated paper.
[0004] The technical solution adopted by the utility model to solve the above-mentioned problem is as follows: the corrugated roller assembly is fixed on the frame as a whole, the corrugated roller assembly includes a first group of corrugated rollers, a second group of corrugated rollers and a power device, the first group of corrugated rollers and the second group of corrugated rollers both include a main roller and a slave roller, the main roller and the slave roller have a corrugated pressing surface, the paper passes between the main roller and the slave roller and is pressed into a corrugated shape, the main rollers are fixedly installed on the frame, the slave rollers are installed on the frame through an adjusting device, the adjusting device adjusts the pressing gap between the slave roller and the main roller, the main rollers of the first group of corrugated rollers and the main rollers of the second group of corrugated rollers are arranged adjacent to each other, and the corrugated structures of the two are convex-convexly arranged relative to each other and keep the linear speed synchronously running. The corrugated roller assembly is mainly used to produce corrugated paper, and to bring the corrugations into relative contact for easy bonding, so there are two sets of corrugated rollers. Two sheets of paper enter the two sets of corrugated rollers respectively and are pressed into corrugated shape. The two sheets of paper form a relative top match due to the positions of the two main rollers. A gluing structure can also be set between the two sets of corrugated rollers to apply glue between the two layers of corrugated paper to achieve fixed bonding in the aligned state. Therefore, the processing requirements without core paper can be achieved, the amount of paper used can be saved, and the thickness and weight of the cardboard can be reduced without reducing the strength.
[0005] Furthermore, the adjustment device includes a rotating arm and an adjusting airbag, one end of the rotating arm is rotatably connected to the frame, the other end of the rotating arm is connected to the adjusting airbag, the base surface of the adjusting airbag is fixed to the frame, the adjusting airbag changes its thickness and changes the angle of the rotating arm, the rotating arm is rotatably connected to the slave roller, and the angle of the rotating arm is changed to adjust the gap between the slave roller and the main roller. The gap between the slave roller and the main roller is mainly used for different paper thicknesses and corrugated sizes. By adjusting the height of the airbag, the adjustability of the slave roller position is achieved, and the structure of the slave roller has a certain working elasticity, reducing the problem of paper breakage due to excessive rigidity.
[0006] Furthermore, the main roller of the second group of corrugated rollers is installed on the frame through an eccentric sleeve, and the eccentric sleeve is a shaft end connection structure with eccentric inner and outer rings, and the eccentric sleeve is connected with a rotating swing rod, and the rotating swing rod is connected with a telescopic link, and the telescopic link is telescopic and changes the angle of the rotating swing rod, and the rotating swing rod rotates to drive the change of the eccentricity of the eccentric sleeve. The working surface of the main roller of the second group of corrugated rollers can be adjusted within a certain range, and the distance is used to compensate for the docking distance caused by adjusting different corrugated heights. The relative distance is changed by rotating the eccentric sleeve, and the adjustment distance range has high precision.
[0007] Furthermore, the main rollers are all connected to a power device, which includes a drive motor, a synchronous belt, and a steering shaft roller. The drive motor is fixed on the frame and outputs power. The synchronous belt is an endless belt and works in a cycle. The synchronous belt passes through the steering shaft roller and turns on one side of one of the main rollers. The two main rollers are respectively connected to the inner and outer sides of the synchronous belt. The drive motor drives the synchronous belt and drives the two main rollers to run at the same linear speed. The power device can be driven by a single drive motor, which reduces the space occupied by the drive structure, and realizes the synchronous reverse rotation of the two main rollers to ensure the consistency of the linear speed.
[0008] Furthermore, a suction plate is provided at the end of the main roller, which is connected to a fan through an air duct, and the fan is fixed on a frame. The suction plate has a plurality of air holes, which are arranged corresponding to the surface edge of the main roller. The suction plate is used to suck air from the working surfaces of the main roller and the slave roller, remove fine particles generated during the paper pressing process, and effectively improve the processing quality.
[0009] Compared with the prior art, the utility model has the following advantages and effects: the design is an improvement on the equipment for producing corrugated paper products with a coreless paper structure, which can achieve rapid positioning between corrugated layers, effectively improve the production efficiency of the product, and the formed paper has high strength and stable quality.
