[0001] The utility model relates to the technical field of chemical coating packaging, in particular to a composite packaging barrel with a sealing structure. Background Art
[0002] The chemical industry holds a vital position in my country's national economy, providing raw materials and products for people's daily needs. With the development and progress of society, people's living standards have gradually improved, leading to a growing demand for chemical products, further driving the development of the chemical industry. Currently, packaging for volatile chemical coatings requires the use of packaging drums.
[0003] Since chemical coatings may have properties such as volatility and corrosiveness, they need to be filled into plastic bags first, and then the plastic bags with the bag openings tied are placed into the packaging barrel. However, the simple knotting method has poor sealing properties and cannot ensure that the packaging is leak-free.
[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a composite packaging barrel with a sealing structure is proposed. Utility Model Content
[0005] The purpose of the present utility model is to provide a composite packaging barrel with a sealing structure to solve the problems raised in the above background technology.

[0008] Furthermore, a concave platform is provided around the top edge of the barrel body, a convex platform is provided around the bottom edge of the barrel cover, and the structures of the barrel body and the barrel cover are consistent.
[0009] Furthermore, the inserts are distributed in a circular pattern with equal intervals along the outer side of the annular concave platform, and a circular hole is opened in the middle of the annular concave platform.
[0010] Furthermore, one end of the return spring away from the pawl is fixedly connected to the annular concave platform, and the annular concave platform is elastically connected to the pawl through the return spring.
[0011] Furthermore, eight of the sliding pins, the cinch rods and the guide seats are provided, and the sliding pins and the cinch rods are integrated structures.

DETAILED DESCRIPTION
[0021] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0022] like Figure 2 and Figure 4 As shown, a composite packaging barrel with a sealing structure includes a barrel body 1 and a driven gear 13. A barrel cover 2 is provided on the top of the barrel body 1, and a hand strap 3 is installed on the top of the barrel cover 2. A card slot 4 is opened on the inner wall of the barrel body 1, and an insert block 5 is provided in the card slot 4. An annular concave platform 6 is provided between the insert blocks 5, and a transmission shaft 7 is rotatably provided on the middle right side of the top surface of the annular concave platform 6. A driving gear 8 and a ratchet 9 are sleeved on the outside of the transmission shaft 7, and a pawl 11 is rotatably connected to the right side of the top surface of the annular concave platform 6 through a rotating shaft 10. The front end of the pawl 11 is connected to a reset spring 12. The driven gear 13 is provided on the left side of the driving gear 8, and the driven gear 1 3 surface is penetrated by a sliding pin 14, a tie rod 15 is provided at the bottom of the sliding pin 14, and a guide seat 16 is sleeved on the outside of the tie rod 15, the insert block 5 is distributed in a circular manner with equal distances along the outer side of the annular concave platform 6, and a circular hole is opened in the middle of the annular concave platform 6, the end of the return spring 12 away from the pawl 11 is fixedly connected to the annular concave platform 6, and the annular concave platform 6 is elastically connected to the pawl 11 through the return spring 12, eight sliding pins 14, eight tie rods 15 and eight guide seats 16 are provided, and the sliding pins 14 and the tie rod 15 are an integrated structure, the guide seat 16 is fixed to the inner surface of the annular concave platform 6, and the guide seat 16 is a "return" type structure.
[0023] The specific operation is as follows: since the driven gear 13 contacts the sliding pin 14 and forms a guiding effect, the ratchet 9 is rotated to provide a rotational force for the driving gear 8, and the driving gear 8 and the driven gear 13 are engaged with each other to transmit power, so that the closing rod 15 moves along the guide seat 16 toward the center of the annular recess 6. The closing rod 15 clamps the knotted bag opening, making it difficult for the bag opening to loosen, thereby improving the packaging qualification rate and sealing performance.
[0024] like Figure 1 and Figure 3As shown, the barrel body 1 includes a plastic inner layer 101, a metal outer layer 102 and an anti-rust oil layer 103, and the outer surface of the plastic inner layer 101 is provided with a metal outer layer 102, and the outer surface of the metal outer layer 102 is coated with an anti-rust oil layer 103. A concave platform is provided around the top edge of the barrel body 1, and a convex platform is provided around the bottom edge of the barrel cover 2, and the structures of the barrel body 1 and the barrel cover 2 are consistent.
[0025] The specific operation is as follows: a layer of anti-rust oil layer 103 is made on the surface of the metal outer layer 102 through anti-rust treatment, which can prevent the outer surface of the metal outer layer 102 from directly contacting the air and oxidizing and rusting. The metal outer layer 102 is set on the outer surface of the plastic inner layer 101, which not only prevents the chemical coating from corroding the metal outer layer 102, but also ensures the overall strength of the barrel body 1, so that the service life can reach more than 20 times.
[0026] In summary, when using the composite packaging barrel with a sealing structure, first place the plastic bag filled with chemical coating inside the barrel body 1, then tie the bag mouth tightly, and then insert the insert block 5 outside the annular concave platform 6 into each of the slots 4 inside the barrel body 1, so that the barrel body 1 and the annular concave platform 6 are coaxially arranged;
[0027] Then the ratchet 9 is manually driven to rotate, and the driving gear 8 and the driven gear 13 are meshed with each other to transmit power, so that the sliding pin 14 is displaced when the driven gear 13 rotates, causing the tie rod 15 to move along the guide seat 16 toward the center of the annular concave platform 6. The tie rod 15 is closed to clamp the bag opening of the knotted packaging bag. Since the pawl 11 is kept in mesh with the ratchet 9 by the elastic force of the return spring 12, the rotation direction of the driving gear 8 and the driven gear 13 is restricted, ensuring that the tie rod 15 will not unfold after closing, making it difficult for the bag opening to be loosened, thereby improving the sealing of the packaging and preventing leakage of chemical coatings;
[0028] Then, the convex portion around the bottom edge of the barrel cover 2 is pressed into the concave portion around the top edge of the barrel body 1, so that the barrel body 1 and the barrel cover 2 are seamlessly connected, achieving a double-layer seal to prevent the chemical coating in the plastic bag from volatilizing and seeping out. The plastic inner layer 101, the metal outer layer 102, and the anti-rust oil layer 103 are arranged from the inside to the outside, which can prevent the outer surface of the metal outer layer 102 from directly contacting the air and causing oxidation and rusting, and at the same time prevent the chemical coating from directly corroding the metal outer layer 102, thereby ensuring the overall strength of the barrel body 1.
[0029] The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
