Description

Technical Field

[0001] This utility model relates to the field of corrugated paper processing technology, and in particular to a preheating device that facilitates the adjustment of the preheating effect of corrugated paper. Background Technology

[0002] Corrugated paper is a sheet-like material made by bonding facing paper and corrugated paper formed by corrugating rollers. In the processing of single-faced corrugated board, the base paper is first rolled into corrugations using corrugating rollers, and then bonded to the single-faced paper sheet to form the board. Before rolling, the base paper needs to be dried and preheated using a preheating device to facilitate forming and bonding.

[0003] Publication number CN214308046U discloses a preheating device for easily adjusting the preheating effect of corrugated paper, relating to the field of corrugated paper processing. It includes a preheating roller for drying corrugated base paper, a first adjusting roller above the preheating roller, and a second adjusting roller below the preheating roller. The corrugated base paper passes sequentially between the first adjusting roller and the preheating roller, and between the preheating roller and the second adjusting roller. A drive mechanism is connected to the first adjusting roller to drive it to rotate around the axis of the preheating roller. This application has the effect of easily adjusting the drying degree of the corrugated base paper.

[0004] While the above-mentioned methods can adjust the degree of drying of corrugated base paper, the corrugated base paper drying process requires multiple roller operations, which is extremely troublesome. Moreover, adjusting the roller area to change the degree of drying is generally ineffective. Therefore, we propose a preheating device that facilitates the adjustment of the preheating effect of corrugated paper. Utility Model Content

[0005] The main purpose of this utility model is to provide a preheating device that facilitates the adjustment of the preheating effect of corrugated paper. By setting up a material guiding unit and adjusting the heating unit, it solves the problem that the corrugated base paper drying process requires multiple roller operations, which is extremely troublesome, and the effect of adjusting the roller area to change the degree of drying is generally not significant.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a preheating device for easy adjustment of the preheating effect of corrugated paper, including a processing box, and further including: a material guiding unit and an adjusting heating unit disposed on the processing box; The material guiding unit includes a carrier box, a rotating shaft, a guide roller, and a motor. The carrier box is fixedly installed at the center of the top surface of the processing box. Two rotating shafts are symmetrically installed on the carrier box. Two guide rollers are respectively sleeved on the outer circumferential surface of the middle end of the two rotating shafts. The motor is installed on the top surface of the processing box and its output end is connected to the end face of one of the rotating shafts. A strip-shaped feeding groove is opened at the center of the top surface of the carrier box. A strip-shaped dropping groove is opened at the center of the top surface and the center of the bottom surface of the processing box, located directly below the strip-shaped feeding groove. The adjusting heating unit includes a bidirectional lead screw, a guide rod, guide blocks, and a strip heating plate. The processing box has a strip mounting groove on each of its two inner walls. The bidirectional lead screw is installed on one of the strip mounting grooves and extends to the outside of the processing box. The guide rod is fixedly installed on the other strip mounting groove. There are four guide blocks in total. Two of the guide blocks are respectively matched with the two symmetrically arranged positive and negative threads on the bidirectional lead screw. The other two guide blocks are movably installed on the guide rod. A strip heating plate is arranged between every two guide blocks.

[0013] Compared with the prior art, the preheating device of this utility model, which facilitates the adjustment of the preheating effect of corrugated paper, has the following beneficial effects: 1. In this utility model, by setting a material guiding unit, the operation of the motor can control one of the rotating shafts to rotate on the carrier box, and one of the guide rollers will rotate inside the carrier box accordingly. The corrugated base paper can be put into the strip feeding groove at the center of the top surface of the carrier box and reach between the two guide rollers. The rotating guide roller can guide the corrugated base paper to move vertically downward. The strip dropping groove located directly below the strip feeding groove and opened at the center of the top and bottom surfaces of the processing box can cooperate with the corrugated base paper to vertically enter and exit the processing box to receive the heating treatment of the heating unit. The equipment has a simple and stable material guiding operation for the corrugated base paper drying process.

[0014] 2. In this utility model, by setting up an adjustment heating unit, the two guide blocks that are engaged with the two threads on the two-way screw outside the processing box can move relative to each other under the force, which can help adjust the spacing of the two strip heating plates. The other two guide blocks can slide and move on the guide rod to adjust the strip heating plates and provide auxiliary support. The preheating effect can be adjusted by adjusting the spacing of the two strip heating plates on the opposite sides of the vertically moving corrugated base paper. The equipment adjustment can change the effect of preheating and drying more conveniently and effectively. Attached Figure Description
