Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper processing, in particular to a flattening machine for corrugated paper production. Background Technique

[0002] Corrugated paper is a plate-shaped object formed by bonding a facing paper and a corrugated paper with a waveform formed by a corrugating roll. Corrugated paper is widely used in the internal and external packaging of various products, such as household appliances, food, beverages, e-commerce goods, fruits and vegetables, express packages, etc. Its high strength and buffering performance effectively protect the packaged goods during transportation.

[0003] Traditional flattening devices may adopt relatively simple mechanical structures, unable to achieve continuous and efficient flattening operations. Manual operation accounts for a relatively large proportion, and the degree of automation is low, increasing labor costs and operation complexity, which leads to low production efficiency and inability to meet the needs of large-scale production. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a flattening machine for corrugated paper production. Aiming at the deficiencies of the prior art, the manual operation of the traditional flattening device accounts for a relatively large proportion, the automation is low, and the flatness of the corrugated paper after flattening is not high, which leads to low production efficiency and low process precision. To solve the problems raised in the above background technique, a new type of flattening machine for corrugated paper production needs to be designed.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A flattening machine for corrugated paper production, including a workbench, electric push rods are fixedly installed at both ends of the workbench, sliders are slidably installed at one ends of the two electric push rods, a pressing plate is fixedly installed at the bottom end of the slider, a plurality of heating tubes are arranged inside the pressing plate, an air cylinder is fixedly installed inside the pressing plate, a sliding rod is slidably installed inside the air cylinder, a spring is arranged between the sliding rod and the inner wall of the air cylinder, a piston is fixedly installed at the free end of the sliding rod, a trapezoidal hole is opened at the position of the piston on the pressing plate, and the piston slides on the surface of the trapezoidal hole. A plurality of exhaust holes are opened on the other side of the pressing plate, filter nets are fixedly installed at both ends of the exhaust holes, a rotating rod is rotatably installed inside the exhaust hole, a small fan is installed at one end of the rotating rod inside the exhaust hole, and a large fan is installed at the other end of the rotating rod outside the exhaust hole.

[0006] As a preferred technical scheme of the utility model, a first roller and a second roller are rotatably installed at the top end of the workbench, and the first roller and the second roller are symmetrically arranged. Corrugated paper slides through between the first roller and the second roller, and brushes are slidably installed on the outer surfaces of the first roller and the second roller close to the large fan.

[0007] As a preferred technical solution of the present utility model, the exhaust holes are installed opposite to the first roller and the second roller, and heat-absorbing materials are provided on the outer surfaces of the first roller and the second roller. The heat-absorbing materials on the outer surfaces of the first roller and the second roller absorb the heat flow led out by the large fan, and at the same time preheat the corrugated paper.

[0008] As a preferred technical solution of the present utility model, a heat-insulating layer is provided on the outer wall of the pressing plate, a heat-insulating plate is fixedly installed outside the heating pipe, a cover plate is installed at the top end of the heating pipe, and both the heat-insulating plate and the cover plate are heat-insulating materials.

[0009] As a preferred technical solution of the present utility model, a plurality of small holes are provided at the bottom end of the pressing plate, and the workbench can be cleaned through the holes at the bottom end of the pressing plate.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. By the mutual cooperation of the workbench, the pressing plate, the heating pipe, the air cylinder, the trapezoidal hole, the piston, the exhaust hole, the small fan and the large fan, the present utility model improves the flatness of the flattened corrugated paper. The heating pipe heats and flattens inside the pressing plate, which can effectively smooth the wrinkles on the surface of the corrugated paper and maintain the flatness of the cardboard. The inside of the pressing plate is in a sealed state, making the heating effect better. When the high temperature inside the pressing plate reaches a certain level, the heat temperature flushes out the piston, and the cold air flows into the inside of the pressing plate through the trapezoidal hole. The small fan inside the exhaust hole on the other side of the pressing plate is driven to rotate by the air flow, and drives the large fan to rotate through the rotating rod, accelerating the air circulation and controlling the temperature inside the pressing plate.

[0013] 2. By setting the first roller, the second roller and the brush, the outer surfaces of the first roller and the second roller are heat-absorbing materials. When the large fan blows the heat flow towards the first roller and the second roller, the heat-absorbing materials on the surface absorb the heat, which can preheat the corrugated paper sliding through between the first roller and the second roller. At the same time, the brush on the roller can clean the roller and the corrugated paper, preventing the sticky dust from affecting the flattening accuracy. BRIEF DESCRIPTION OF THE DRAWINGS
