Description

Technical Field

[0001] The utility model relates to the technical field of corrugated cardboard processing, in particular to a preheating device for cleanly producing corrugated cardboard. Background Art

[0002] Corrugated cardboard is a multi-layered adhesive body consisting of at least one corrugated core paper layer and one cardboard layer. It has high mechanical strength and can withstand collisions and falls during transportation. When producing and processing corrugated cardboard, a related preheating device is often required to achieve bonding between the two layers of corrugated cardboard. The patented technology discloses a preheating device for corrugated cardboard production and processing (authorization announcement number CN217495499U). This patented technology discloses a preheating device for corrugated cardboard production and processing, including a preheating box body, a conveyor device installed on the preheating box body, a placement plate fixedly installed through the side wall of the preheating box body, a chute at the bottom of the preheating box body, an abutment plate and a limit block fixedly installed on the inner wall of the preheating box body, and a gear rotatably connected to the inner wall of the preheating box body. The chute is provided with a pushing mechanism, which extends into the placement plate and is slidably connected thereto, the pushing mechanism meshes with the gear, and the limit block is provided with a driving mechanism, which meshes with the gear. The utility model has a reasonable structural design. After the corrugated cardboard is preheated and pressed, it can automatically push out the pressed corrugated cardboard, eliminating the operator's manual removal of the corrugated cardboard, and avoiding the situation where the corrugated cardboard is still at a high temperature and causes burns to the operator. This patented technology solves the problem in the prior art that after the corrugated cardboard is preheated, in order to ensure that the corrugated cardboard does not cool down, the corrugated cardboard is pressed in the preheating device. After pressing, the operator needs to take out the pressed corrugated cardboard and place it, and the corrugated cardboard may still be at a high temperature, which can easily burn the operator.

[0003] However, in the prior art, the corrugated cardboard is preheated on one side, which makes it difficult to preheat the corrugated cardboard uniformly. Therefore, it is necessary to solve the problem of comprehensive preheating of the corrugated cardboard in the prior art.

[0004] Therefore, those skilled in the art provide a preheating device for clean production of corrugated cardboard to solve the problems raised in the above background technology. Utility Model Content

[0038] The corrugated cardboard passes through the conveying frame structure 2 and can be transported on the preheating frame structure 1 to the preheating turning structure 3 for preheating treatment;

[0039] The conveying frame structure 2 starts the servo motor 206, which drives the transmission roller 205 to rotate. The transmission roller 205 drives the conveyor belt 207 to move, so that the corrugated cardboard on the conveyor belt 207 moves along the movable top frame 102 and the movable top frame 2 103 to the positioning structure 31;

[0040] Before the corrugated cardboard is preheated, the servo motor 105 is started, which drives the screw 104 to rotate. The screw 104 is spirally driven along the pulley bracket 1 202, so that the movable bracket 201 passes through the pulley bracket 1 202 and the pulley bracket 2 203 and moves along the preheating bracket 101, so that the conveyor belt 207 is away from the preheating turning structure 3, so that the corrugated cardboard can be preheated and pretreated;

[0041] By starting the corresponding cylinder 1 3102, the angle of the clamping plate 3103 can be adjusted to a right angle state, and the corrugated cardboard can be clamped and positioned. After the corrugated cardboard is positioned by the positioning structure 31, the servo motor 306 is started, and the servo motor 306 starts to drive the bevel gear 304 to rotate. The bevel gear 304 engages the bevel gear ring 305 to rotate, so that the bevel gear ring 305 drives the preheating ring cylinder 301 to rotate along the outer shaft frame 303, so that the corrugated cardboard on the positioning structure 31 is turned up and down. After the clamping plate 3103 is unfolded by the cylinder 1 3102, the hot air blower 307 can preheat the upper and lower surfaces of the corrugated cardboard respectively, so that the entire corrugated cardboard is preheated evenly.
