Technical Field
[0001] This utility model relates to the field of seamless paper tube dustproof technology, and in particular to a high-strength seamless paper tube dustproof structure. Background Technology
[0002] High-strength seamless paper tubes are paper products with excellent physical properties and environmental characteristics. They are made of high-strength paper through precision rolling processes. Their surface is seamless and smooth, and they have extremely high compressive strength. They are widely used in many industries such as textiles, printing, packaging, and construction for winding, supporting, and protecting materials such as yarn, paper, and film. High-strength seamless paper tubes not only have the advantages of being lightweight, low-cost, and easy to recycle, but also are more stable and durable due to their seamless structure. They can effectively prevent the intrusion of contaminants such as dust and moisture, ensuring the safety and cleanliness of packaged items.
[0003] For high-strength seamless paper tubes used in food packaging, routine transportation and storage of the paper tubes can cause dust to fall onto the outer surface of the paper tubes, which can easily breed bacteria and contaminate the packaged food, thus causing food safety issues. If disposable vacuum packaging bags are used to package the paper tubes to prevent dust, it will greatly increase the workload of paper tube packaging and increase production costs.

Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0027] Example 1: Please refer to Figures 1 to 6 :
[0028] This utility model proposes a high-strength seamless paper tube dustproof structure, including: a dustproof box 1, with a paper tube inlet 101 opened on the upper edge of the right wall of the dustproof box 1, an inclined guide plate 103 fixedly connected inside the dustproof box 1, the inclined guide plate 103 being inclined from left to right, an inclined inlet 104 being provided at the left end of the inclined guide plate 103, the right edge of the inclined guide plate 103 being located at the lower edge of the paper tube inlet 101, and a paper tube drawer being opened on the lower edge of the front wall of the dustproof box 1. At the outlet 105, a push plate storage frame 4 is installed on the lower rear edge of the dustproof box 1. The push plate storage frame 4 is connected to the dustproof box 1. A discharge push plate 5 is slidably connected inside the push plate storage frame 4. A push plate guide rod 502 is fixedly connected to the rear end of the discharge push plate 5. The push plate guide rod 502 slidably passes through the push plate storage frame 4. Seamless paper tubes are put in and taken out through the paper tube inlet 101 and the paper tube outlet 105 to avoid dust from contacting the paper tubes and causing contamination.
[0029] In this embodiment, a paper tube insertion support plate 102 is fixedly connected to the lower right edge of the paper tube insertion inlet 101, and a first rotating cover plate 2 is connected to the upper right edge of the paper tube insertion inlet 101 via a hinge. The first rotating cover plate 2 covers the insertion support plate 102. First, the paper tube is inserted through the paper tube insertion inlet 101, and the insertion support plate 102 serves as an external support structure to further facilitate the insertion of the paper tube. The first rotating cover plate 2 covers the paper tube insertion inlet 101 to prevent dust and bacteria from falling into the dustproof box 1 through the paper tube insertion inlet 101 and contaminating the paper tube under normal conditions.
[0030] In this embodiment, the upper front edge of the paper tube outlet 105 is connected to a second rotating cover 3 via a hinge, and the second rotating cover 3 covers the front of the paper tube outlet 105. Under normal conditions, the second rotating cover 3 covers the front of the paper tube outlet 105 to seal the paper tube outlet 105 and prevent dust from falling into the dustproof box 1 through the paper tube outlet 105.
[0031] In this embodiment, a storage frame guide hole 401 is provided through the middle of the rear wall of the push plate storage frame 4. The storage frame guide hole 401 is slidably connected to the push plate guide rod 502. The left and right ends of the discharge push plate 5 are respectively bent backward to form a push plate limiting flange 501. The outer end faces of the two push plate limiting flanges 501 are in contact with the inner wall of the dustproof box 1. The rear end of the push plate guide rod 502 is connected to the guide rod limiting push block 503 by screws. A push plate reset spring 504 is sleeved on the push plate guide rod 502. The front end of the push plate reset spring 504 is fixedly connected to the rear surface of the discharge push plate 5, and the rear end of the push plate reset spring 504 is... The inner surface of the fixed connection push plate storage frame 4 is normally in a retracted state, and the front surface of the discharge push plate 5 is flush with the inner rear wall of the dust box 1. When taking out the paper tube, the guide rod limiting push block 503 is pushed forward, causing the discharge push plate 5 to move forward and apply a forward pushing force to the paper tube at the bottom layer inside the dust box 1, causing the paper tube at this layer to move forward. The front end of the paper tube protrudes out of the paper tube extraction port 105, making it convenient for the user to take out the paper tube. There is no need to open the box during the process of taking out the paper tube, and the discharge push plate 5 is automatically moved back to its original position after being pushed forward and then reset by the action of the push plate reset spring 504.
[0032] The working principle of this embodiment is as follows: First, when storing paper tubes in the dustproof box 1, the first rotating cover plate 2 is rotated upward, the paper tube is placed above the insertion support plate 102 and pushed to the left, so that the paper tube rolls to the left along the inclined guide plate 103. After the inclined guide plate 103 rolls to the position of the inclined inlet 104, it falls into the dustproof box 1 for arrangement and storage. The setting of the first rotating cover plate 2 can prevent external dust from falling into the dustproof box 1. When taking out the paper tube, the guide rod limiting push block 503 is pushed forward, so that the discharge push plate 5 moves forward, and a forward pushing force is applied to the paper tube at the bottom layer inside the dustproof box 1, so that the paper tube at this layer moves forward and the front end of the paper tube protrudes out of the paper tube extraction outlet 105. The user takes out the paper tube by hand or tool and pulls it forward. The paper tubes inside the dustproof box 1 automatically roll down and arrange themselves under their own gravity. The dustproof box 1 can be used for the sealed storage and transportation of paper tubes.
