Description

Technical Field

[0001] This utility model relates to the field of paper product manufacturing technology, specifically to a drying device for paper product manufacturing. Background Technology

[0002] Corrugated cardboard is a common packaging material. The production and processing of common corrugated cardboard requires the use of adhesive to bond different types of cardboard together. After bonding, the adhesive must be allowed to dry before the next processing step can proceed.

[0003] In order to improve drying efficiency, dryers are generally used to dry paperboard. However, ordinary dryers cannot limit and clamp the paperboard. During the drying process, the paperboard may shift, affecting the quality of the final product.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a drying device for paper product manufacturing, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a drying device for paper product manufacturing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drying device for paper product manufacturing, comprising a base frame, pre-pressing rollers, and an anti-loosening device. A drying chamber is installed on the top of the base frame, and a conveyor belt is installed on the inner bottom of the drying chamber. Pre-pressing rollers are arranged horizontally on both sides of the conveyor belt, and side plates are installed on both sides of one end of the pre-pressing rollers. Lifting rods are installed on both sides of the top of the side plates, and an L-shaped top frame is installed on the top of the lifting rods. Fitting grooves are opened on both sides of the horizontal end of the L-shaped top frame, and fitting plates are embedded in the inner side of the fitting grooves.

[0007] The drying chamber has anti-loosening devices installed in the middle of the inner walls on both sides. The anti-loosening devices include mounting plates, telescopic air rods, movable side plates, support rods, side fixed ends, and fixed rollers. Side fixed ends are installed on both sides of the mounting plates, and movable side plates are axially connected to the inner side of each set of side fixed ends. Fixed rollers are axially connected to the inner side of the movable side plates. Support rods are installed on the inner side of the middle of the movable side plates. Telescopic air rods are axially connected to the support rods and the mounting plates.

[0008] A top cover is installed in the middle of the top wall of the drying chamber, and a drive motor is installed at the top center of the top cover. A fan blade is installed at the bottom center of the top cover, and heaters are symmetrically distributed on both sides of the bottom wall of the top cover.

[0009] Furthermore, a drive motor is installed on the outside of the drying chamber, and the drive motor and the conveyor belt are connected in a transmission connection.

[0010] Furthermore, the L-shaped top frame and the upper edges of the drying chamber are fixedly installed on both sides.

[0011] Furthermore, the interlocking plate and the side plate are vertically welded and fixedly connected.

[0012] Furthermore, the drive motor and the fan blades are connected by a transmission.

[0013] Furthermore, the mounting plate forms a pneumatic transmission structure through the telescopic air rod and the support rod.

[0014] Furthermore, the side fixed end is movably connected to the movable side plate and the fixed roller via a shaft connection.

[0015] This utility model provides a drying device for paper product manufacturing, which has the following beneficial effects:

[0016] 1. This utility model uses a conveyor belt as the direct conveyor for paper products. Pre-pressing rollers are symmetrically distributed on both sides of the belt. The pre-pressing rollers can press the paper products together from top to bottom, maintain the stability of the upper and lower sheets of the paper products, and prevent displacement.

[0017] When moving to the middle processing area, if the length is long, the pressing rollers on both sides can be pre-fixed to prevent displacement; if the length is narrow, the anti-loosening device in the middle of the drying chamber wall can drive the support rod and movable side plate to rotate under the action of the telescopic air rod, thereby driving the fixed roller to rotate and press the paper products at the bottom, thus ensuring that they do not shift during drying and affect production quality.

[0018] Because the roller is an elastic component, it can undergo elastic deformation, thereby ensuring the squeezing force on the paperboard, and can clamp and convey paperboards of different thicknesses.

[0019] 2. In this utility model, the two sides of the pre-compression roller are fixed by a shaft connection through side plates, and the height is adjusted by a lifting rod, which is convenient to adjust according to the thickness of the paper product.

[0020] A fitting plate is vertically fixed to the surface of the side panel. It is fixedly connected to the side panel. When the side panel is raised or lowered, it is inserted into the fitting groove in the L-shaped top frame for corresponding raising and lowering. The fitting plate can seal the inner space of the top cover, reduce heat loss during drying, and make the drying effect better and more efficient.

[0021] 3. This utility model uses a horizontally distributed heater and a fan blade driven by a motor to form a drying unit. It uses the generated hot air to dry paper products, which can conveniently dry cardboard, quickly dry the glue, and improve drying efficiency. Attached Figure Description
