[0002] Packaging boxes are commonly used packaging materials in various production processes. In today's rapidly evolving environment of automated production, automated box packing is particularly important for the entire automated production process. However, due to the close size of the incoming materials and the packaging boxes, a high degree of accuracy in the box's position is required, necessitating the use of positioning devices for precise positioning.

[0003] According to Chinese Patent Publication No. CN210653862U, a packaging box positioning device includes a sensing mechanism, a base, and a positioning structure disposed on the base. The positioning structure includes a first positioning structure for adjusting the packaging box along a first direction and a second positioning structure for adjusting the packaging box along a second direction. The sensing mechanism is electrically connected to the positioning structure. When the sensing mechanism detects that the packaging box enters the area corresponding to the positioning structure, the first positioning structure limits the packaging box along the first direction, and the second positioning structure limits the packaging box along the second direction. This packaging box positioning device, before automatic material packing, uses the first and second positioning structures to accurately position the packaging box and uses the sensing mechanism to detect the position of the packaging box, solving the problem of accurate packaging box positioning and effectively replacing manual labor, reducing the labor intensity of employees. However, the mechanism on the top of the base of the aforementioned device is exposed, making it prone to dust accumulation or collision damage to related components, affecting the positioning effect. Therefore, a packaging positioning device with protective functions is proposed to solve the above-mentioned problems. Utility Model Content

[0022] The protective shell 32 is provided with a sealing mechanism 4 at the top. The sealing mechanism 4 includes a cover plate 41, which is located at the top of the protective shell 32. A U-shaped plate 42 is connected to the bottom of the cover plate 41. L-shaped plates 43 are connected to both the left and right sides of the cover plate 41. A clamping plate 44 is slidably connected to the L-shaped plate 43. A through hole is opened on the outer wall of the U-shaped plate 42. The clamping plate 44 passes through the outer wall of the protective shell 32 and is inserted into the through hole. The clamping plate 44 is slidably connected to the protective shell 32. A connecting piece 47 is connected to the bottom of the clamping plate 44. One end of a spring 48 is connected to the outer wall of the connecting piece 47, and the other end of the spring 48 is connected to the outer wall of the L-shaped plate 43.
