Description

Technical Field

[0001] This utility model relates to the field of flame-retardant PE film blow molding production technology, specifically, to a flame-retardant PE film blow molding machine. Background Technology

[0002] The flame-retardant PE film blow molding machine is a specialized device for producing flame-retardant polyethylene (PE) film. This equipment uses blow molding technology to heat and extrude polyethylene resin, then blows it into a film using gas to form the desired film shape. Flame-retardant PE film incorporates flame retardants during production, giving it fire-resistant properties and enabling it to self-extinguish rapidly under fire, thus improving safety. The machine's main features are high efficiency and precision, allowing for control over film thickness, width, and flame-retardant properties. It is widely used in packaging, wire and cable, and building materials industries.

[0003] In existing PE film blow molding machines, the PE film is typically cooled in an air-cooling zone during the blow molding process. However, a common problem exists during this cooling process: the PE film is not effectively scraped during cooling. Because the temperature of the blow-molded PE film is still high and the film surface is not fully cured, the cooling in the air-cooling zone is insufficient to ensure the flatness of the film. This leads to the PE film easily shrinking and deforming during cooling, especially when the film thickness or stress is uneven. The shrinkage phenomenon is more obvious, which may cause wrinkles, ripples, or even uneven stretching on the film surface. This shrinkage and deformation not only affects the appearance quality of the film but may also lead to a decline in the performance of the film in subsequent processing or use. For example, the dimensional accuracy of the film may not meet the requirements, resulting in unqualified packaging products, or problems such as film surface damage and insufficient strength may occur during application. Therefore, those skilled in the art provide a flame-retardant PE film blow molding machine to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a flame-retardant PE film blow molding machine, which solves the problem in the existing PE film blow molding machine where the PE film is usually cooled in an air-cooling zone during the blow molding process. However, a common problem exists in the air-cooling process: the PE film is not effectively scraped during cooling. Because the temperature of the blow-molded PE film is high and the film surface is not fully cured, the cooling in the air-cooling zone is insufficient to ensure the flatness of the film. This causes the PE film to easily shrink and deform during cooling, especially when the film thickness or stress is uneven, the shrinkage phenomenon is more obvious, which may cause wrinkles, ripples or even uneven stretching on the film surface. This shrinkage and deformation not only affects the appearance quality of the film, but may also lead to a decline in the performance of the film in subsequent processing or use.

[0038] The film leveling mechanism 6 consists of a guide bar 601 and a reciprocating screw 602. The reciprocating screw 602 drives the reciprocating slider 604 to slide along the guide bar 601 by rotation, thereby driving the scraper 609 to scrape and level the surface of the flame-retardant PE film body 1. The guide bar 601 ensures that the slider moves along the correct trajectory through the guide groove 603, avoiding deviation or uneven scraping. This structure effectively avoids shrinkage and deformation of the film surface, ensures the flatness of the film, and improves the appearance quality and subsequent performance of the film. The scraper 609 is fixed on the spur gear 608. As the spur gear 608 rotates, the scraper 609 is driven to adhere to the surface of the flame-retardant PE film body 1 through meshing transmission. The scraper 609 and the film surface come into contact with each other, which can effectively remove any ripples or uneven parts that may exist on the film surface. This design effectively avoids shrinkage or deformation of the film surface due to lack of timely scraping during the air-cooling process, ensuring the quality of the film.

[0039] As one implementation method in this embodiment, please refer to Figures 7-8 As shown, multiple synchronous gears 7 are arranged in a ring at the lower end of the support ring 503.

[0040] The synchronous gear 7 and the internal gear ring 505 transmit power through gear meshing, ensuring that multiple film leveling mechanisms 6 can operate synchronously. Each synchronous gear 7 is connected to the lower outer side of the reciprocating screw 602, ensuring precise gear transmission. Through the transmission of power by the synchronous gear 7, the coordinated operation of multiple film leveling mechanisms 6 can be realized, avoiding unevenness on the film surface caused by asynchronous operation of different leveling mechanisms, thereby improving the quality of the film.

[0041] Working principle: The support assembly 2 consists of multiple support columns 201, which are connected to multiple support rods 205 through a first support ring 202. The support assembly 2 supports the entire device, ensuring that each component maintains stable operation. The first bearing 203 and the first rotating ring 204 ensure the rotational smoothness of the support structure, enabling the device to withstand pressure from all directions without deformation during operation. This structure ensures the stable operation of other mechanisms, while improving the durability and operating efficiency of the equipment. The transmission mechanism 3 is fixedly connected to the support rods 205 through the upper support plate 301, transmitting driving force. The fixed connection between the sleeve 303 and the upper rotating plate 304 enables the upper rotating plate 304 to operate stably, thereby driving multiple film leveling mechanisms 6 to rotate and operate. Multiple fourth bearings 305 ensure the smooth rotation of the upper rotating plate 304. The design of the transmission mechanism 3 effectively distributes power, enabling multiple film leveling mechanisms 6 to operate synchronously, improving the working efficiency of the system.

[0042] The drive mechanism 4 consists of an external gear ring 401 and a support plate 402. The drive motor 404 meshes with the external gear ring 401 through a drive gear 405 to achieve transmission. The drive motor 404 provides power to drive the gear system. Through the gear meshing of the external gear ring 401, the power is transmitted to the sleeve 303, which drives the upper rotating disk 304 to rotate. The drive mechanism 4 can transmit power efficiently and stably, ensuring the smooth operation of the entire system and improving the overall efficiency of the equipment. The synchronization mechanism 5 consists of a second support ring 501 and a second rotating ring 502. The internal gear ring 505 meshes with the synchronization gear 7 to ensure that multiple film leveling mechanisms 6 can work synchronously. The support rotating ring 503 provides the necessary stability and support through sliding cooperation with the second support ring 501, ensuring accurate and smooth synchronous transmission. This structure ensures the synchronous operation of the film leveling mechanism 6 and improves the overall operating accuracy of the equipment.

[0043] The film leveling mechanism 6 consists of a guide bar 601 and a reciprocating screw 602. The reciprocating screw 602 rotates to drive the reciprocating slider 604 to slide along the guide bar 601, thereby driving the scraper 609 to scrape and level the surface of the flame-retardant PE film body 1. The guide bar 601, through the guide groove 603, ensures that the slider moves along the correct trajectory, avoiding deviation or uneven scraping. This structure effectively avoids shrinkage and deformation of the film surface, ensures the flatness of the film, and improves the appearance quality and subsequent performance of the film. The scraper 609 is fixed on a spur gear 608. As the spur gear 608 rotates, the scraper 609 is driven to adhere to the surface of the flame-retardant PE film body 1 through meshing transmission. The contact between the surfaces effectively removes any ripples or unevenness that may exist on the membrane surface. This design effectively prevents shrinkage or deformation of the membrane surface during air cooling due to lack of timely scraping, ensuring membrane quality. The synchronous gear 7 transmits power through gear meshing with the internal gear ring 505, ensuring that multiple membrane leveling mechanisms 6 can operate synchronously. Each synchronous gear 7 is connected to the lower outer side of the reciprocating screw 602, ensuring precise gear transmission. Through the power transmission of the synchronous gear 7, the coordinated operation of multiple membrane leveling mechanisms 6 can be achieved, avoiding unevenness on the membrane surface caused by asynchronous operation of different leveling mechanisms, thereby improving membrane quality.
