Description

Technical Field

[0001] This utility model relates to the field of casting machines, specifically a stretch film casting machine. Background Technology

[0002] A stretch film casting machine is a complete set of equipment that uses melt casting and rapid cooling processes to produce polyethylene / polypropylene stretch film. It can efficiently and stably produce stretch film with high transparency, extremely uniform thickness and excellent tensile properties to meet the needs of large-scale and high-strength packaging in industry.

[0003] In existing technologies, stretch film casting machines can efficiently and stably produce stretch films with high transparency, extremely uniform thickness, and excellent tensile properties. After the stretch film is produced, its surface temperature is high. Therefore, workers will install cooling rollers and water baths at the discharge port of the stretch film casting machine. The cooling rollers and water baths work together to cool the stretch film. However, the water temperature inside the water bath will increase as the working time increases. At this point, workers need to stop the machine, remove the hot water from the water bath, and add cold water. This shutdown maintenance not only extends the working time and reduces work efficiency, but also requires the use of a large amount of additional water, which increases production costs to some extent. Utility Model Content

[0004] To address the shortcomings of existing technologies, the water temperature inside the water bath increases as the working time extends, requiring operators to shut down the equipment, remove the hot water from the water bath, and refill with cold water. This shutdown not only extends working time and reduces efficiency but also requires a large amount of additional water, thus increasing production costs to some extent. This invention proposes a wrapping film casting machine.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a stretch film casting machine, including a casting machine body, a connecting base fixedly connected to one side of the casting machine body, a cooling roller body and a guide roller provided on the top of the connecting base, a water bath tank fixedly connected to the top of the connecting base, a positioning roller rotatably connected to the inner cavity of the water bath tank, a cooling mechanism provided at the bottom of the water bath tank, and a scraping mechanism provided on one side of the guide roller. The cooling mechanism includes a water tank located directly below a water bath. An inlet pipe, an outlet pipe, and heat dissipation fins are fixedly connected to the inner cavity of the water tank. One end of each inlet and outlet pipe is fixedly connected to the inner cavity of the water bath. A water pump is fixedly connected to the surface of each inlet and outlet pipe. One side of the heat dissipation fins extends through one side of the water tank. A mounting plate is fixedly connected to one side of the water tank. A cooling fan is fixedly connected to the inner cavity of the mounting plate. Auxiliary components are provided within the inner cavity of the water tank.

[0006] Preferably, the auxiliary component includes a U-shaped plate, one side of which is fixedly connected to one side of the water tank. A servo motor is fixedly connected to the inner cavity of the U-shaped plate. The output end of the servo motor passes through one side of the U-shaped plate and is fixedly connected to a stirring rod. One end of the stirring rod passes through one side of the water tank.

[0007] Preferably, the wiping mechanism includes a mounting base plate, the bottom of which is fixedly connected to the top of the connecting base, a connecting rod fixedly connected to the top of the mounting base plate, and a mounting block fixedly connected to one side of the connecting rod. There are two mounting blocks, and a squeegee is movably engaged on one side of each of the two mounting blocks.

[0008] Preferably, a sealing rubber block is fixedly connected to the surface of the heat dissipation fins, and one side of the sealing rubber block is fixedly connected to one side of the water tank.

[0009] Preferably, the surface of the heat dissipation fins is provided with heat dissipation through holes, and multiple heat dissipation through holes are provided, and the multiple heat dissipation through holes are arranged in a honeycomb pattern.

[0010] Preferably, a reinforcing ring is rotatably connected to the surface of the stirring rod, and one side of the reinforcing ring is fixedly connected to one side of the water tank.

[0011] Preferably, a snap-fit ​​block is fixedly connected to one side of the scraper, and a snap-fit ​​hole is provided on one side of the mounting block, wherein the surface of the snap-fit ​​block is movably snapped into the inner cavity of the snap-fit ​​hole.

[0012] The advantages of this utility model are: This invention utilizes two water pumps in conjunction with inlet and outlet pipes to achieve water circulation within the water bath and tank. Auxiliary components can accelerate the water flow rate within the tank, allowing for faster cooling. A scraper mechanism removes water stains from the surface of the stretch film. The cooling mechanism ensures continuous water circulation within the water bath, preventing excessively high water temperatures. This reduces the need for frequent maintenance shutdowns and improves work efficiency. The scraper mechanism also cleans the surface of the stretch film passing through the water bath, preventing water residue buildup. This addresses the issue of water temperature rising over time, requiring shutdowns to remove hot water and refill with cold water. Such shutdowns not only extend working hours and reduce efficiency but also consume large amounts of water, increasing production costs. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a stretch film casting machine. (Refer to...) Figure 1 and Figure 2A stretch film casting machine includes a casting machine body 1, a connecting base 2 fixedly connected to one side of the casting machine body 1, a cooling roller body 3 and a guide roller 6 provided on the top of the connecting base 2, a water bath 4 fixedly connected to the top of the connecting base 2, a positioning roller 5 rotatably connected to the inner cavity of the water bath 4, a cooling mechanism 7 provided at the bottom of the water bath 4, and a scraping mechanism 8 provided on one side of the guide roller 6. The cooling mechanism 7 includes a water tank 701, which is located directly below the water bath 4. The inner cavity of the water tank 701 is fixedly connected to an inlet pipe 702, an outlet pipe 703, and a heat dissipation fin 705. One end of the inlet pipe 702 and the outlet pipe 703 are fixedly connected to the inner cavity of the water bath 4. A water pump 704 is fixedly connected to the surface of the inlet pipe 702 and the outlet pipe 703. One side of the heat dissipation fin 705 extends through one side of the water tank 701. A mounting plate 706 is fixedly connected to one side of the water tank 701. A cooling fan 707 is fixedly connected to the inner cavity of the mounting plate 706. An auxiliary component 708 is provided in the inner cavity of the water tank 701.

[0018] The casting machine body 1 can efficiently and stably produce stretch film with high transparency, extremely uniform thickness and excellent tensile properties to meet the needs of large-scale and high-strength packaging in industry. After the stretch film inside the casting machine body 1 is produced, it will first pass through the cooling roller body 3. The cooling roller body 3 can rapidly cool the molten plastic film to set its shape, which directly determines the gloss, transparency and initial physical properties of the film. At the same time, the casting machine body 1 and the cooling roller body 3 are existing technologies in this field, so they will not be described in detail here. After the stretch film passes through the connecting base 2, it will pass through the interior of the water bath 4 and undergo secondary cooling. The positioning roller 5 inside the water bath 4 can provide positioning for the stretch film, so that it can pass smoothly through the water bath 4 and flow to the guide roller 6. The guide roller 6 can guide the stretch film, so that the stretch film can pass through the guide roller 6 and pass through the scraping mechanism 8. The scraping mechanism 8 can scrape off the water stains on the surface of the stretch film. The stretch film with the water stains scraped off will flow to the next process. Furthermore, the water bath 4, water tank 701, inlet pipe 702, and outlet pipe 703 are interconnected. Inlet pipe 702 and outlet pipe 703 are also connected to water pump 704. Operators can start water pump 704 to pump water from the water bath 4 into inlet pipe 702, which then flows into water tank 701. Water tank 701 provides a mounting point for heat dissipation fins 705, which absorb heat from the water in water tank 701, preventing the water temperature from becoming too high. Additionally, water tank 701 can connect to mounting plate 706 to provide power to cooling fan 707. The cooling fan 707 provides a connection function, and through its own operation, it accelerates the airflow on the surface of the cooling fins 705, so that the surface temperature of the cooling fins 705 can be quickly cooled by the outside air, and the cooling fins 705 can more easily absorb the heat contained in the water source inside the water tank 701. At the same time, the staff can use the auxiliary component 708 to stir the water source inside the water tank 701, so that the hot and cold water inside the water tank 701 can be mixed more quickly. At the same time, another water pump 704 can be started to pump the water source inside the water tank 701 into the outlet pipe 703, and then discharge it into the water bath 4 through the outlet pipe 703, thereby realizing water circulation.

[0019] Reference Figure 1 and Figure 3 The auxiliary component 708 includes a U-shaped plate 7081, one side of which is fixedly connected to one side of a water tank 701. A servo motor 7082 is fixedly connected to the inner cavity of the U-shaped plate 7081. The output end of the servo motor 7082 passes through one side of the U-shaped plate 7081 and is fixedly connected to a stirring rod 7083. One end of the stirring rod 7083 passes through one side of the water tank 701. The water tank 701 provides installation and connection for the U-shaped plate 7081, and the U-shaped plate 7081 is connected to the servo motor 7082. Meanwhile, the servo motor 7082 is connected to the stirring rod 7083. The operator can start the servo motor 7082 and drive the stirring rod 7083 to rotate. The rotation of the stirring rod 7083 can agitate the water flow inside the water tank 701, making the hot and cold water inside the water tank 701 more evenly mixed. At the same time, it can also allow the water inside the water tank 701 to quickly pass through the heat dissipation fins 705, so that the heat absorption effect of the heat dissipation fins 705 can be fully utilized.

[0020] Reference Figure 4 and Figure 5The squeegee mechanism 8 includes a mounting base plate 801. The bottom of the mounting base plate 801 is fixedly connected to the top of the connecting base 2. A connecting rod 802 is fixedly connected to the top of the mounting base plate 801. A mounting block 803 is fixedly connected to one side of the connecting rod 802. There are two mounting blocks 803. A scraper 804 is movably engaged on one side of each mounting block 803. The connecting base 2 provides a connection to the connecting rod 802 through the mounting base plate 801. At the same time, the connecting rod 802 is connected to the mounting block 803. The mounting block 803 provides installation and connection for the scraper 804. After the stretch film is positioned by the guide roller 6, it will pass between the two scrapers 804. The two scrapers 804 can cooperate with each other to scrape the upper and lower surfaces of the stretch film, so that the surface of the stretch film is less likely to have a large amount of water stains, which would affect the normal processing of subsequent processes.

[0021] Reference Figure 2 A sealing rubber block 9 is fixedly connected to the surface of the heat dissipation fin 705. One side of the sealing rubber block 9 is fixedly connected to one side of the water tank 701. The heat dissipation fin 705 provides installation and connection for the sealing rubber block 9. At the same time, the sealing rubber block 9 can be connected to the water tank 701. The sealing rubber block 9 can seal the gap between the heat dissipation fin 705 and the water tank 701, so that the water inside the water tank 701 is not easy to flow out from the connection between the heat dissipation fin 705 and the water tank 701, thereby preventing water leakage.

[0022] Reference Figure 2 and Figure 3 The surface of the heat dissipation fin 705 is provided with heat dissipation through holes 10. Multiple heat dissipation through holes 10 are provided and are arranged in a honeycomb pattern. By opening multiple honeycomb heat dissipation through holes 10 on the surface of the heat dissipation fin 705, the contact area between the heat dissipation fin 705 and the air can be increased to a certain extent. This allows the cooling fan 707 to cool the heat dissipation fin 705 more smoothly, and the heat dissipation fin 705 can better absorb the heat from the water source inside the water tank 701.

[0023] Reference Figure 3A reinforcing ring block 11 is rotatably connected to the surface of the stirring rod 7083. One side of the reinforcing ring block 11 is fixedly connected to one side of the water tank 701. The surface of the snap-fit ​​block 13 is movably snapped into the inner cavity of the snap-fit ​​hole 12 to connect the stirring rod 7083 to the reinforcing ring block 11. At the same time, the reinforcing ring block 11 is connected to the water tank 701. The setting of the reinforcing ring block 11 can seal the connection between the stirring rod 7083 and the water tank 701, so that the water inside the water tank 701 is not easy to leak out from the connection between the stirring rod 7083 and the water tank 701. It can also provide support for the stirring rod 7083 to a certain extent, so that the stirring rod 7083 can more smoothly complete the stirring of the water inside the water tank 701.

[0024] Reference Figure 5 A snap-fit ​​block 13 is fixedly connected to one side of the scraper 804, and a snap-fit ​​hole 12 is provided on one side of the mounting block 803. The surface of the snap-fit ​​block 13 and the inner cavity of the snap-fit ​​hole 12 can be movably snapped into the scraper 804, which can provide installation and connection for the snap-fit ​​block 13. By opening the snap-fit ​​hole 12 on one side of the mounting block 803, the snap-fit ​​block 13 and the snap-fit ​​hole 12 can be snapped into each other, so that when the staff needs to replace and maintain the scraper 804, the scraper 804 can be disassembled more smoothly and conveniently.

[0025] Working Principle: Before use, the operator needs to inject water into the water bath 4 and turn on one of the water pumps 704 to pump the water from the water bath 4 into the water tank 701 through the inlet pipe 702. Simultaneously, the operator turns on the other water pump 704 to return the water from the water tank 701 to the water bath 4 through the outlet pipe 703. When the wrapping film enters the water bath 4 through the positioning roller 5, its surface temperature is rapidly cooled by the water inside the water bath 4. If the water temperature inside the water bath 4 becomes too high, the operator can start one of the water pumps 704, which will pump the water from the water bath 4 into the water tank 701 through the inlet pipe 702. The heat contained in the water entering the water tank 701 is absorbed by the heat dissipation fins 705, while the cooling fan 70... 7 will accelerate the airflow on the surface of the heat dissipation fins 705, enabling the heat dissipation fins 705 to dissipate heat quickly. The operator can also turn on the servo motor 7082, and the operation of the servo motor 7082 will drive the stirring rod 7083 to rotate. The rotation of the stirring rod 7083 will agitate the water inside the water tank 701, making the hot and cold water inside the water tank 701 evenly mixed. At the same time, the water can pass through the heat dissipation fins 705 more quickly. Then, another water pump 704 will pump the water inside the water tank 701 through the water outlet pipe 703 to the inside of the water bath 4 to achieve water circulation. After passing through the water bath 4, the wrapping film will pass through the guide roller 6 and enter the middle of the two scrapers 804. The scrapers 804 will scrape the surface of the wrapping film, making it less likely for a large amount of water stains to remain on the surface of the wrapping film.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
