Abstract

This utility model discloses a rapid cooling and shaping device for coated paper, including symmetrically arranged L-shaped plates. The top of the L-shaped plates is connected to a cooling roller structure. Water tank one and water tank two are fixed on the L-shaped plates respectively. The rapid cooling and shaping device for coated paper also includes: a driving structure fixed to one end of the cooling roller structure; and a cooling water circulation structure fixed on water tank one and water tank two and connected to the end of the cooling roller structure. The water pump in the water circulation structure draws water from water tank one and enters the cold water chamber inside the cooling roller through water pipe one and water pipe two. The cooling roller cools and shapes the coated paper. The cooled water then flows through drain pipe one and drain pipe two into water tank two for temporary storage. During the temporary storage process, the water is cooled, avoiding the situation where the water cooled by the cooling roller flows into the same water tank, causing the water temperature to rise and the cooling effect to gradually decrease as it circulates through the cooling roller.

Description

Technical Field

[0001] This application relates to a rapid cooling and shaping device for coated paper. Background Technology

[0002] The manufacturing process of coated paper involves coating polyethylene particles onto the paper surface using a casting machine. After cooling, the polyethylene and paper are firmly bonded together. Its main characteristics are oil and water resistance, and heat sealing capability. Different applications utilize these unique properties, making coated paper widely used in various fields, such as food packaging and industrial packaging.

[0003] Existing technology disclosure number CN212636344U discloses a water-cooling circulation system for a coating machine, including a frame. The frame is horizontally rotatably connected from left to right along the paper transport direction to a first cooling roller, a second cooling roller, and a shaping roller, all with hollow interiors. Each of the first and second cooling rollers has a rotary joint for inlet and outlet of cooling water at one end. A cooling water circulation device is provided between the outlet of the rotary joint at the end of the first cooling roller and the inlet of the rotary joint on the second cooling roller. A water-separating cylinder is coaxially arranged inside both the first and second cooling rollers. Several sets of water-blocking components are fixed axially on the inner walls of the first and second cooling rollers and on the periphery of the water-separating cylinders. This invention maximizes the retention time of cooling water within the first and second cooling rollers for thorough conduction, significantly improving the cooling efficiency of the cooling rollers.

[0004] The cooling devices used for cooling and shaping mostly involve circulating cooling water through multiple rotating cooling rollers. The laminated paper is then wrapped around the outer walls of these rollers for cooling and shaping. These cooling rollers are mostly cylindrical and hollow, filled with circulating cooling water. However, the water that has cooled the coated paper through the cooling rollers flows into the same water tank, such as the water-cooled circulation system mentioned above. The temperature of the cooled water will rise, and as it circulates through the cooling rollers and the water tank, the water temperature in the tank will increase, gradually reducing the cooling effect.

[0005] Therefore, it is desirable to provide a device for rapid cooling and shaping of coated paper. Utility Model Content

[0006] This embodiment provides a rapid cooling and shaping device for coated paper, which solves the problem that the water after cooling the coated paper by the cooling roller flows into the same water tank, and the temperature of the cooled water will rise.

[0014] Furthermore, the cooling water circulation structure includes a water pump, a pumping pipe, a first water supply pipe, a second water supply pipe, a first drain pipe, a second drain pipe, a first valve, a connecting pipe, and a second valve. The water pump is fixed to the top of the first water tank, and a pumping pipe is fixed to the input end of the water pump. The other end of the pumping pipe passes through the top of the first water tank and extends to the bottom of the first water tank.

[0015] Furthermore, a water supply pipe is fixed to the output end of the water pump, and the other end of the water supply pipe passes through the cooling roller three and is connected to the cold water chamber. Water supply pipes two are fixed on both sides of the water supply pipe one, and the other end of the water supply pipe two passes through the cooling roller one and the cooling roller two and is connected to the cold water chamber.

[0016] Furthermore, a drain pipe is fixed to the cold water chamber at the end of the cooling roller three away from the water supply pipe one, and the other end of the drain pipe one passes through the top of the water tank two and communicates with the inside of the water tank two.

[0017] Furthermore, both cooling roller one and cooling roller two have a drain pipe two fixed to the cold water chamber at the end away from the water supply pipe two, and the other end of the drain pipe two is connected to the drain pipe one.

During the temporary storage process, the water can be cooled. After cooling, valve 2 on the connecting pipe is opened to draw out the water in water tank 2 for reuse. Setting up two water tanks can cool and store the discharged water, avoiding the situation where the water that has cooled the coated paper through the cooling roller flows into the same water tank, causing the water temperature in the tank to rise and gradually reduce the cooling effect as it circulates through the cooling roller.

[0045] Working principle and usage: All electrical components in this application are externally connected to a power supply and control device during use. First, the coated paper is passed around cooling rollers 201, 202, and 303 respectively. During cooling, water is pumped from water tank 4 by water pump 601 and flows through water pipes 603 and 604 into the cold water chamber 204 inside the cooling rollers. The cooling rollers cool and shape the coated paper. The cooled water then flows through drain pipes 605 and 606 into water tank 5 for temporary storage. During temporary storage, the water is cooled. After cooling, the connecting pipe 6 is opened. Valve 609 on 08 draws water from water tank 5 for reuse. Setting up two water tanks allows for the cooling and storage of the discharged water, preventing the water that has cooled the coated paper after passing through the cooling rollers from flowing into the same water tank, which would cause the water temperature in the tank to rise and gradually reduce the cooling effect as it circulates through the cooling rollers. At the same time, the motor 301 in the drive structure 3 drives the gear 302 to rotate, and the gear rings 303, 304, and 305 meshing with the gear 302 rotate accordingly, thereby causing the cooling rollers 201, 202, and 203 to rotate, accelerating the cooling speed of the coated paper.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
