Description

Technical Field

[0001] The present application relates to the technical field of paper barrel processing, and in particular to a square paper barrel cover shaping device. Background Art

[0002] Most products are currently packaged in traditional wooden boxes, plastic, or foam. With growing awareness of environmental protection, the availability of wooden boxes is becoming increasingly limited. Furthermore, wood utilization is low, resulting in high costs. Wooden boxes also have poor shock resistance, and pests and diseases can affect their quality. Plastic or foam packaging is difficult to recycle and can cause serious environmental pollution. Paper barrels are convenient, lightweight, and recyclable.

[0003] For example, Chinese patent application number CN02259448.5 discloses a square all-paper barrel, which consists of a barrel body, a barrel bottom and a barrel cover. The barrel body is square and shrinks inward to form a step near the upper end, and forms an upper skirt. At the same time, it is folded inward 90 degrees at the bottom end; the barrel bottom is fixedly connected to the inward folded part of the bottom end of the barrel body; the barrel cover includes a cover ring that can be buckled onto the outer side of the upper skirt of the step, and a cover plate fixedly connected to the cover ring and can be pressed against the inner side surface of the upper skirt.

[0004] Regarding the above-mentioned related technologies, the inventor believes that there are the following defects:

[0005] Based on the assembly requirements of the barrel body and the barrel cover, the inner diameter of the barrel cover is generally slightly larger than the inner diameter of the barrel body opening. Since the paper barrel cover is made of cardboard, the opening of the paper barrel cover is more likely to deform during processing and transportation. In order to ensure that the barrel body and the barrel cover are assembled more tightly, before the barrel cover is closed, the staff needs to use both hands to squeeze the side of the barrel cover towards the middle to make the side of the barrel cover slightly concave inward. However, the method of manually squeezing and shaping the barrel cover is not only inefficient, but also the strength and amplitude of each manual squeezing and shaping of the barrel cover are difficult to control, which will cause some barrel covers to deform excessively or the deformation is not obvious, so it needs to be improved.

[0032] The following is combined with Figure 1-2 This application is described in further detail.

[0033] The embodiment of the present application discloses a square paper drum cover shaping device. Figure 1 and Figure 2 The square paper drum cover shaping device includes a workbench 1, and a notch 111 is provided on each side of the top of the workbench 1. The four notches 111 are arranged along the four sides of a rectangle respectively. A vertically arranged shaping pressing plate 2 is hinged at the notch 111. The rotation axis of the shaping pressing plate 2 is arranged horizontally and along the length direction of the corresponding notch 111. The top of the shaping pressing plate 2 extends out of the upper surface of the workbench 1 for squeezing and shaping the side of the square paper drum cover. The bottom of the shaping pressing plate 2 extends into the interior of the workbench 1. A driving unit 3 is provided inside the workbench 1. The driving unit 3 is used to drive the bottom of the shaping pressing plate 2 to rotate. An elastic reset unit 4 is provided between the side of the workbench 1 and the bottom of the shaping pressing plate 2.

[0034] The beneficial technical effects of the square paper drum cover shaping device of the embodiment of the present application are roughly as follows:

[0035] The staff puts the square paper barrel cover upside down on the top surface of the workbench 1 and between the four shaping press plates 2. Then they operate and start the driving unit 3, thereby driving the four shaping press plates 2 to squeeze the four sides of the square paper barrel cover inward at the same time. As a result, the four sides of the shaped square paper barrel cover will be concave to a certain extent from the middle to the inside. When the square paper barrel cover is subsequently closed on the barrel body, the fit will be tighter, the square paper barrel cover will not bulge outward, and will be flatter and more beautiful. The above method does not require the staff to use both hands to squeeze manually, which is more efficient. In addition, the strength and amplitude of each squeezing are similar, which will not easily cause some barrel covers to deform excessively or the deformation is not obvious, thereby indirectly improving the quality of the product.

[0036] In this embodiment, in order to ensure that the four shaping platens 2 can start working at the same time, four groups of driving units 3 are provided.
