Description

Technical Field

[0001] This utility model relates to the field of blown film machine technology, and in particular to a raw material pretreatment feeding device for blown film machines that reduces crystal point defects. Background Technology

[0002] With the development of blow molding technology, blown film machines have been widely used in the production of plastic films. In the process of producing plastic films by blow molding machines, it is necessary to fully mix various plastic raw materials in the appropriate proportions.

[0003] If the internal structure of the existing equipment is not cleaned in a timely manner, raw materials may easily remain inside. Over time, these residual raw materials may undergo deterioration, oxidation, or other reactions. When the equipment is fed again, they may be mixed into the new raw materials, which can easily lead to crystal point defects. Utility Model Content

[0004] This utility model discloses a raw material pretreatment feeding device for blown film machines to reduce crystal point defects. It aims to solve the technical problem that if the device is not cleaned in time, the raw material is easy to remain inside, which will deteriorate and oxidize over a long period of time, and old raw materials will be mixed in when feeding again, causing crystal point defects.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a raw material pretreatment feeding device for blown film machines to reduce crystal point defects, comprising a main body, wherein a cleaning component is provided on the main body, the cleaning component includes a rotary motor, the power output shaft of the rotary motor is connected to a rotating component via a coupling, an annular fixing component is fixedly connected to the top of the rotary motor, the inner side of the annular fixing component is fixedly connected to the outer side of the main body, a pull rope is movably connected to the inner side of the rotating component, a circular hole is opened on the side of the main body near the rotary motor, the inner side of the circular hole is movably connected to the outer side of the pull rope, an annular component is fixedly connected to the front end of the pull rope, an annular scraper is fixedly connected to the side of the annular component near the pull rope, a through hole is opened on the inner side of the bottom end of the annular component, a circular rod is movably connected inside the through hole, the two ends of the circular rod are fixedly connected to the two ends of the inner side of the main body, and a tension spring is fixedly connected to the side of the annular component away from the pull rope.

[0006] The device, equipped with a main body and cleaning components, cleans materials inside. A rotary motor starts, driving a rotating component to rotate. The rotary motor, acting as a power source, provides initial power for the entire cleaning process. As the rotating component rotates, its inner side is movably connected to a pull rope, causing the pull rope to move. The pull rope passes through a circular hole on the main body, converting the circular motion of the rotating component into linear motion. A ring-shaped component is fixedly connected to the front end of the pull rope. When the pull rope moves, it causes the ring-shaped component to move along a circular rod. Because both ends of the circular rod are fixed inside the main body, they act as guides, ensuring the ring-shaped component can only move along the rod. The device moves in a straight line along the direction of the round rod. A ring-shaped scraper is fixedly connected to the ring component. When the ring component moves, it drives the ring scraper to move synchronously. The scraper cleans the material inside the device. When the rotary motor reverses or stops providing tension, the tension spring will play its role. One end of the tension spring is connected to the ring component. Under the action of its elastic restoring force, it will pull the ring component back to its initial position, so that the ring component and the ring scraper are reset, preparing for the next cleaning. During the process, the inside of the device is cleaned in time, so that no material remains inside. When feeding again, old material will not be mixed in, effectively avoiding the occurrence of crystal point defects.

[0007] In a preferred embodiment, the main body has an inner shell inside. One end of the tension spring is fixedly connected to one side of the inner shell. Holes are provided at both ends of the inner shell, and the inside of the holes is fixedly connected to both ends of the outer side of the round rod. A circular groove is provided at the end of the inner shell near the rotary motor, and the inside of the circular groove is movably connected to the outside of the pull rope. The outside of the annular scraper is in contact with the inside of the inner shell. The outside of the annular fixing member is movably connected to the inside of the inner shell. A gearbox is fixedly connected to the front end of the main body. A drive motor is connected to the front end of the gearbox via a coupling. A filter is fixedly connected to the side of the main body away from the gearbox. A stirring rod is fixedly connected to one end of the gearbox and movably connected to the inside of the inner shell. A fixing seat is fixedly connected to the outside of the main body. A feed hopper is provided on the outside of the main body. Circular grooves are provided at the top of the outer sides of both the main body and the inner shell, and the inside of the circular grooves is fixedly connected to the outside of the bottom end of the feed hopper. A curved heater is fixedly connected to the outside of the inner shell. Waste discharge ports are fixedly connected to the outside of the bottom ends of both the main body and the inner shell.

[0008] In a preferred embodiment, a cleaning assembly is provided on one side of the main body. The cleaning assembly includes a rotating shaft, a belt movably connected to the outer side of the rotating shaft, and the inner side of the belt away from the rotating shaft is movably connected to the outer side of the bottom end of the rotating component. A water pipe is movably connected to the outer side of the rotating shaft, and a water tank is fixedly connected to the bottom end of the water pipe. A slot is formed on the inner side of the water pipe and the side of the main body near the rotating shaft. The outer side of the slot is movably connected to the outer side of the water pipe. The outer side of the water pipe is fixedly connected to the inner side of the annular component. An annular transfer box is fixedly connected to the front end of the water pipe. One side of the annular transfer box is fixedly connected to the side of the annular component away from the annular scraper. Multiple rectangular holes are formed on the inner side of the annular transfer box, and hidden spray heads are fixedly connected inside each rectangular hole.

[0009] By incorporating a cleaning assembly, during the cleaning process following raw material cleaning, the rotating component drives the belt, which transmits power to the rotating shaft, causing it to rotate. As the shaft rotates, the movable water pipe moves accordingly. Since the outer side of the water pipe is fixedly connected to the inner side of the annular component, the annular component, driven by the cleaning assembly, moves synchronously with the water pipe and the annular transfer box. One end of the water pipe is connected to a water tank, and the other end to the annular transfer box, maintaining communication during movement to provide a channel for subsequent water spraying. The cleaning solution in the water tank is transported to the annular transfer box via the water pipe. Multiple rectangular holes are provided inside the annular transfer box, each with a hidden spray head fixedly connected. As the annular transfer box moves with the annular component, the hidden spray heads spray cleaning solution into the device, rinsing away any residue from the raw materials after cleaning. This achieves the cleaning function. The cleaning process begins immediately after the initial cleaning action, eliminating the need for additional waiting or process switching, thus shortening the overall cleaning time.

[0010] As can be seen from the above, the raw material pretreatment feeding device for blown film machines that reduces crystal point defects provided by this utility model has the technical effect of timely cleaning of the inside of the device, ensuring that the raw material does not remain inside, and preventing the old raw material from being mixed in when feeding again, thus effectively avoiding the occurrence of crystal point defects.

[0022] Working principle: During raw material pretreatment feeding, drive motor 3 starts and transmits power to gearbox 2. Drive motor 3 serves as the initial power source for the entire device, providing the power foundation for subsequent actions. Gearbox 2 processes the power of drive motor 3 by speed change and other processes, and then transmits the power to stirring rod 9. Stirring rod 9 rotates inside inner shell 11, which can perform pretreatment and stirring operations on raw materials. After the raw material pretreatment feeding is completed, rotary motor 801 starts, driving rotating component 802 to start rotating. When rotating component 802 rotates, the movable pull rope 8... 04. The movement begins. The pulling rope 804 passes through the corresponding circular holes and grooves on the main body 1 and the inner shell 11, converting the circular motion of the rotating part 802 into linear motion. The front end of the pulling rope 804 is fixedly connected to the annular part 805. The movement of the pulling rope 804 drives the annular part 805 to move along the circular rod 808. Both ends of the circular rod 808 are fixed to the inside of the main body 1 and pass through the holes at both ends of the inner shell 11, serving as a guide and ensuring that the annular part 805 can only move in a straight line. The annular scraper 806 fixedly connected to the annular part 805 moves synchronously, using the scraper to scrape the main body 1 and... The residual material inside the inner shell 11 is scraped and cleaned. During the movement of the annular component 805, the tension spring 807 is stretched. When the rotary motor 801 reverses or stops providing tension, the tension spring 807, relying on its elastic restoring force, pulls the annular component 805 back to its initial position, resetting the annular component 805 and the annular scraper 806, preparing for the next cleaning cycle. Simultaneously, as the rotating component 802 rotates, it drives the rotating shaft 501 to rotate via the belt 502. The rotation of the rotating shaft 501 drives the water pipe 503, which is movably connected to it, to move. Since the outer side of the water pipe 503 is fixedly connected to the inner side of the annular component 805, when the annular component 805 moves, it moves the water pipe 503 and the annular transfer box 505 synchronously. The water pipe 503 connects the water tank 504 and the annular transfer box 505 to ensure a continuous connection. The cleaning fluid in the water tank 504 is transported to the annular transfer box 505 through the water pipe 503. The hidden water spray head 506 inside the annular transfer box 505 sprays the cleaning fluid into the device to further rinse the residual raw materials after cleaning by the cleaning component 8. Finally, the cleaned waste is collected through the waste drop outlet.
