The connection between the barrel body and the barrel bottom in the production process of paper barrels mainly relies on the sealing process, so the accuracy and precision of the sealing equipment and the quality of the sealing process operation will affect the overall quality of the paper barrel. Therefore Barrel hoop groove arc The rationality of shape and reserved size has a great impact on the quality of paper drums. The groove of the barrel hoop is too deep and the arc curvature is small, which makes it easy to crush the quality of the barrel body's raw and auxiliary materials during the molding process paperboard drum The raw materials used for the quality impact bucket include kraft paper, plywood, strip steel, adhesives, etc. What is currently worrying is that most of the competition among cardboard barrel production enterprises remains in price competition, with very few participating in competition based on quality. In order to compete with customers, enterprises have to resort to cutting corners and using low weight paper instead of high weight paper. If the groove of the drum hoop is too shallow and the arc curvature is too large, it directly affects the connection between the bottom of the drum and the drum body. The amount of iron plate rolled onto the drum body is relatively small, resulting in weak bonding between the cardboard and plywood. So the molding process operation should regularly check the size bending of each part of the sealing mold, and workers should strictly follow the process specifications to prevent deviations caused by this fibre drum The tightness of the bottom joint varies, which affects the fit between the bucket bottom and the bucket body.
In order to increase the strength of the paper drum, upper and lower clamps are installed at the upper and lower openings of the drum. The clamp in the middle of the drum is called the upper clamp, and the lower clamp is called the lower clamp. The main function of the upper and lower clamps is to ensure the strength of the paper barrel and maintain the roundness of the barrel mouth and body; Strengthening the closure device can effectively position the lid and mouth of the barrel, maintaining good interchangeability; The fixed barrel body and plywood form a sturdy whole.
Paper barrels have been widely used in various industries, from industry to agriculture, from mechanical assurance to food packaging. Paper barrels have many advantages, such as reliable product performance and low cost. So while being practical, we also need to ensure exquisite and artistic quality. This can increase the beauty and value of the product, making it more widely accepted.
The contradiction between unique and innovative design and convenient and economical manufacturing requires careful coordination. Generally speaking, regardless of the shape, it can be implemented or approximated using a certain structure. However, when implementing some shapes, the manufacturing difficulty and cost may increase significantly. For most commercial packaging, the production volume is often large, so the economy should be considered first when designing the shape, and the embodiment of product concept can also be compensated by performance design.
In summary, during the design process, the external shape and manufacturing materials of the container should be determined based on the size, weight, shape, and other conditions of the packaged material, and a three-dimensional rendering should be drawn to provide a basis for structural design. It should be emphasized that 3D renderings play an extremely important guiding role in packaging container design. In many cases, with only working drawings or physical boxes, people may not be able to fold the required paper box at all. Therefore, before completing the design, it is often necessary to redraw the 3D rendering to highlight its structural characteristics To guide people in correctly shaping containers.
