Description

Technical Field

[0001] This utility model relates to the technical field of hot coating equipment for cardboard, and in particular to a hot coating equipment for honeycomb cardboard. Background Technology

[0002] Honeycomb paperboard is made based on the principle of honeycomb structure in nature. It is a new type of sandwich structure environmentally friendly and energy-saving material made by bonding corrugated base paper into countless hollow three-dimensional regular hexagons to form a whole load-bearing component - paper core, and then bonding face paper to both sides. In the processing of honeycomb paperboard, it is often necessary to improve the gluing equipment to apply glue to the surface of the honeycomb paperboard.

[0003] Currently, when applying glue to honeycomb paperboard, a glue roller is often used in conjunction with a transmission belt. The honeycomb paperboard is then passed through the glue roller to achieve the function of applying glue. However, during the process of the honeycomb paperboard passing through, the hot melt glue usually fills the entire glue roller. Since the sides of the glue roller are usually longer than the honeycomb paperboard, glue dripping occurs on both sides. This not only increases the difficulty of cleaning the transmission belt, but also leads to the waste of hot melt glue. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where, during the passage of honeycomb paperboard, hot melt adhesive usually fills the entire glue roller, and the sides of the glue roller are usually longer than the honeycomb paperboard, resulting in glue dripping on both sides. This not only increases the difficulty of cleaning the transmission belt, but also leads to the waste of hot melt adhesive.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a hot-coating device for honeycomb cardboard, including a mounting frame, a conveyor belt inside the mounting frame, a U-shaped platform fixedly connected to the upper end of the mounting frame, a hot melt adhesive box fixedly embedded in the top of the U-shaped platform, a glue roller rotatably connected to the lower end of the U-shaped platform, a glue flow channel in the middle of the U-shaped platform, and locking pins slidably connected to both ends of the U-shaped platform, extending to the outside of the U-shaped platform. The locking pins are slidably connected inside the glue flow channel. A positioning mechanism is provided on the mounting frame, and the positioning mechanism is drivenly connected to the locking pins on both sides. By blocking the sides of the glue flow channel with the locking pins on both sides, the hot melt adhesive can be made to fall only on the glue roller portion within the cardboard roller brush area, reducing the waste of hot melt adhesive and improving resource utilization.

[0006] In a preferred embodiment, the positioning mechanism includes mounting platforms fixedly connected to both ends of the mounting frame. A threaded rod is rotatably connected to the upper end of each mounting platform, and positioning clamps are threaded to both ends of the threaded rod. The helical directions of the two ends of the threaded rod are opposite. A drive motor is fixedly mounted on one side of the mounting platform, and the output end of the drive motor is fixedly connected to the threaded rod. The positioning clamps enable the positioning of the cardboard, preventing it from shifting while moving on the conveyor belt.

[0007] In a preferred embodiment, each of the two positioning clamps is fixedly connected to a connecting rod at one end away from each other. A synchronizing rod is fixedly connected to the end of the connecting rod. The end of the synchronizing rod away from the connecting rod is fixedly connected to the corresponding locking pin. The connecting rod and the synchronizing rod work together to drive the locking pins on both sides to move simultaneously, so that the positioning clamps can drive the locking pins on both sides to move synchronously during the movement.

[0008] In a preferred embodiment, guide rods are fixedly connected between the mounting platforms, and the guide rods are slidably connected to the two positioning clamps. The guide rods serve to guide the positioning clamps in a sliding manner, improving the stability of the positioning clamps' movement.

[0009] In a preferred embodiment, the lower end of the hot melt adhesive box is fixedly connected to two opposing guide plates at the guide plate. The two guide plates are arranged in a V-shape to guide the hot melt adhesive, so that the hot melt adhesive can fall accurately onto the upper end of the glue roller.

[0010] In a preferred embodiment, both positioning clamps are fixedly attached with rubber soft pads at one end close to each other to prevent damage to the cardboard during compression and fixing.

[0011] In a preferred embodiment, the mounting frame is fixedly connected to a guide plate at the output end of the conveyor belt, and protective frames are fixedly connected to both sides of the guide plate. The guide plate facilitates the export of the glued cardboard, while the protective frames prevent the cardboard from detaching from the guide plate during export.

[0012] In a preferred embodiment, the mounting bracket is fixedly connected to each of the four corners at the bottom, and the multiple legs serve to support the device.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. This utility model is equipped with a locking pin, a guide plate, a glue roller and a conveyor belt.

A positioning mechanism is provided on the mounting frame 1, and the positioning mechanism is drivenly connected to the locking pins 12 on both sides. By blocking the sides of the glue flow channel 19 by the locking pins 12 on both sides, the hot melt adhesive can be made to fall only on the glue roller 14 part in the cardboard roller brush area, reducing the waste of hot melt adhesive and improving the utilization rate of resources.

[0024] like Figure 1-4As shown, the positioning mechanism includes mounting platforms 9 fixedly connected to both ends of the mounting frame 1. A threaded rod 15 is rotatably connected to the upper end of the mounting platform 9. Positioning clamps 6 are threaded to both ends of the threaded rod 15, and the helical directions of the two ends of the threaded rod 15 are opposite. A drive motor 8 is fixedly installed on one side of the mounting platform 9, and the output end of the drive motor 8 is fixedly connected to the threaded rod 15. The positioning clamps 6 can realize the function of positioning the cardboard and prevent the cardboard from shifting when moving on the conveyor belt 5.

[0025] like Figure 1-4 As shown, each of the two positioning clamps 6 is fixedly connected to a connecting rod 11 at one end away from each other. A synchronizing rod 10 is fixedly connected to the end of the connecting rod 11. The end of the synchronizing rod 10 away from the connecting rod 11 is fixedly connected to the corresponding locking pin 12. Through the cooperation of the locking pin 12 and the connecting rod 11, the positioning clamps 6 can drive the locking pins 12 on both sides to move synchronously during the movement.
