Description

TECHNICAL FIELD

[0001] The utility model relates to corrugated paperboard production technical field, specifically is a kind of forming mould for corrugated paperboard production. BACKGROUND

[0002] The forming mould for corrugated paperboard production is one of the core equipment in the production process of corrugated paperboard, and its main function is to press the corrugated paper into wave-shaped corrugated paper and bond with face paper and back paper to form corrugated paperboard with specific corrugation type and strength. The forming mould for corrugated paperboard production is usually composed of corrugated rollers, gluing devices, pressure rollers, racks and transmission systems, etc. After the corrugated paper is preheated by a preheater, it enters between the upper and lower corrugated rollers and is pressed into wave-shaped corrugated paper under the action of occlusion pressure.

[0003] For example, the Chinese patent "corrugated forming machine for corrugated paperboard production" with publication number CN219820812U includes two support columns, a driving mechanism is installed between the two support columns, and an adjusting mechanism is arranged on the top of each support column. A support sleeve is fixedly connected to the top of each adjusting mechanism, a threaded column is spirally connected to the top center of each support column, and a limiting disc is fixedly connected to the bottom of each threaded column. A second bearing is fixedly connected inside each adjusting mechanism, a connecting rod is fixedly connected between the two second bearings, and an adjusting press roller is fixedly connected between the two connecting rods. A connecting plate is fixedly connected between the two support columns of each group, the driving mechanism includes a driving motor fixedly connected to one side of the support column, a fixed press roller is fixedly connected to the output end of the driving motor, and a first bearing is installed between the two ends of the fixed press roller and the support column.

[0004] Although the above-mentioned prior art can realize the production of corrugated paperboard, in actual use, on the one hand, it is difficult to replace the corrugated rollers, which are usually fixedly arranged on the machine table, so that different devices need to be replaced for producing corrugated paperboard of different shapes, thereby reducing the efficiency of paperboard production. On the other hand, the production effect of corrugated paperboard is not good enough, and the raw paperboard is prone to position deviation under the action of the corrugated rollers before being pressed, thereby reducing the precision of corrugated paperboard production. Therefore, it does not meet the existing needs, and thus we propose a forming mould for corrugated paperboard production. UTILITY MODEL CONTENTS

[0005] The utility model aims to provide a forming mould for corrugated paperboard production to solve the problems of difficulty in replacing the corrugated rollers and poor production effect of corrugated paperboard mentioned in the background.

[0008] Preferably, the central position of the outside of the second fixed link is fixedly provided with a second corrugated roller, the central position of the outside of the first fixed link is fixedly provided with a first corrugated roller, and the first corrugated roller corresponds to the position of the second corrugated roller.

[0009] Preferably, the upper end of the machine table is fixedly provided with a mounting frame on both sides, one end of the mounting frame close to the outside of the machine table is fixedly provided with two second hydraulic telescopic devices, the second hydraulic telescopic devices are symmetrically arranged, and the telescopic end of the second hydraulic telescopic device extends to the other end of the mounting frame.

[0010] Preferably, one end of the telescopic end of the second hydraulic telescopic device is fixedly provided with a guide rod, the inside of the guide rod is provided with a sliding groove, and the sliding groove is through structure.

[0011] Preferably, the inside of the sliding groove is provided with five rollers, and the upper and lower ends of the rollers are rotatably connected with the inner wall of the sliding groove.

[0012] Preferably, the central position of the upper end of the machine table is fixedly provided with a first hydraulic telescopic device, and the upper end of the telescopic end of the first hydraulic telescopic device is fixedly connected with the mounting seat.

[0013] Compared with the prior art, the utility model has the beneficial effects that:

[0014] (1) This utility model allows for quick replacement of corrugated rollers via through holes and bolts. When different corrugated rollers need to be replaced, rotate the nut to move it outside the bolt until the nut separates from the bolt. At this point, pull the bolt out of the through hole and remove the first and second corrugated rollers from between the first and second flanges, respectively. Then, place the new first and second corrugated rollers between the first and second flanges, respectively. Finally, reinsert the bolt into the through hole and fix it with the nut, thereby improving the convenience of corrugated roller replacement.

[0015] (2) This utility model can guide and limit the board material through the guide rod and the second hydraulic telescopic device. Before corrugated cardboard production, the distance between the guide rods is adjusted according to the specific production needs. At this time, the second hydraulic telescopic device is activated so that the telescopic end of the second hydraulic telescopic device extends. The extension of the telescopic end of the second hydraulic telescopic device drives the guide rods to move towards each other until the guide rods are moved to the appropriate position. Then, the raw cardboard is placed between the first corrugated roller and the second corrugated roller. At the same time, the two ends of the cardboard contact and slide with the rollers to avoid the position of the corrugated cardboard during the production process, thereby improving the production accuracy of the cardboard.

[0016] (3) The present invention can adjust the height of the first corrugated roller by setting the first hydraulic telescopic device. Before corrugated cardboard production, the height of the first corrugated roller is adjusted according to the specific production needs. At this time, the first hydraulic telescopic device is activated, so that the telescopic end of the first hydraulic telescopic device retracts. The retraction of the telescopic end of the first hydraulic telescopic device drives the first fixed rod and the first corrugated roller to move downward together until the first corrugated roller is moved to the appropriate position. At this time, the subsequent operation of corrugated cardboard is carried out to avoid the raw cardboard from being damaged due to excessive pressure, thereby improving the strength and stiffness of the corrugated cardboard.

The inside of the first flange 6 and the second flange 12 are provided with four through holes 20. The through holes 20 are distributed in a ring at equal intervals and are through-hole structures. Bolts 9 are provided inside the through holes 20. One end of the bolt 9 extends to the outside of the first flange 6 and the second flange 12. Nuts 10 are sleeved on the outside of one end of the bolt 9 to facilitate the disassembly and assembly of the first flange 6 and the second flange 12 through the bolts 9 and nuts 10.

[0025] Please see Figure 1 , Figure 2 and Figure 3Mounting brackets 14 are fixedly installed on both sides of the upper end of the machine base 1. Two second hydraulic telescopic devices 15 are fixedly installed on one end of the mounting bracket 14 near the outside of the machine base 1.
