[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 8The utility model provides a technical solution: a heat shrink film machine for cosmetic packaging, comprising a conveying device 1, a heating box 2 and a pair of angle pressing components respectively arranged on both sides of the top of the conveying device 1. The angle pressing device of the present application is suitable for heat shrink film packaging of cosmetic boxes. The feed end of the conveying device 1 is used to cooperate with the existing film cutting machine (not shown in the figure) to form a heat shrink film production line. The angle pressing component comprises a cylinder 8 and a pair of guide plates 3 fixedly installed on the top of the conveying device 1. A slide 5 is fixedly installed on the top of the conveying device 1. The cylinder 8 is fixedly installed at the central position of the slide 5. A pair of clamping blocks 10 are fixedly installed on the slide 5. A pair of support rods 6 are fixedly installed on one side of the guide plate 3. The pair of support rods 6 are respectively fixedly connected to the clamping blocks 10. 10 is the prior art, in which the position of the support rod 6 on the slide 5 is locked by a pair of bolts, one end of the guide plate 3 is provided with an inclined section, and the inclined section expands toward the opening of the heating box 2. The advantage of this arrangement is that it provides a guiding effect for the packaging box, and a pressing plate 4 is rotatably installed on one side of the guide plate 3. The pressing plate 4 is made of a material with both thermal conductivity and heat resistance. A through hole 7 for accommodating the pressing plate 4 is provided on the side wall of the guide plate 3. The advantage of this arrangement is that when the packaging box is pressed at an angle, the material can be smoothly transported out through the conveying device 1. A pair of L-shaped rods 11 are rotatably installed at the output end of the cylinder 8, and the L-shaped rods 11 extend to contact with the pressing plate 4. A guide block 12 is fixedly installed at the central position of the pressing plate 4, and an angle is formed between the guide block 12 and the pressing plate 4. The guide block 12 A sliding hole is provided on the top, and a pair of connecting rods 13 are rotatably installed on the output end of the cylinder 8. One end of the connecting rod 13 is integrally formed with a vertical ear. One end of the L-shaped rod 11 is fixedly connected to the connecting rod 13, and the L-shaped rod 11 is fixedly installed at the vertical ear position, and the other end extends to the sliding hole that penetrates the guide block 12 and is rotatably sleeved with a sliding sleeve 14. By setting the sliding sleeve 14, the friction between the L-shaped rod 11 and the guide block 12 is effectively reduced, so that the rotation of the pressure plate 4 is smoother and less prone to jamming. A limit plate 9 is fixedly installed on the top of the slide 5, and a pair of slots are provided on the limit plate 9. The purpose of this setting is to facilitate the adjustment of the extension distance of the limit plate 9 on the conveying device according to needs. The L-shaped rod 11 is rotatably sleeved with a roller 15 below the sliding sleeve 14, and the roller 15 and the limit plate 9 When the packaging box is transported by the conveying device 1 to the center of a pair of angle pressing components, the output end of the cylinder 8 cooperates with the L-shaped rod 11 to drive a pair of pressing plates 4 to make a circular motion until they collide with the corners of the packaging box and flatten the sharp corners of the heat shrink film. When the present application is in operation, the packaging box with the heat shrink film is sent to the heating box 2 by the conveying device 1. When it moves to the position of the angle pressing component, the output end of the cylinder 8 in the pair of angle pressing components is controlled to extend, and a pair of L-shaped rods 11 contact the limit plate 9 through the roller 15, and make relative movement on one side of the limit plate 9 until they are away from each other. The L-shaped rod 11 slides in the sliding hole of the guide block 12 through the sliding sleeve 14 and drives the pressing plate 4 to make a 90° circular motion. At this time, the four groups of pressing plates 4 cooperate to collide with the corners of the cosmetic packaging box and flatten the sharp corners of the heat shrink film.The present application forms an angle pressing assembly in the heating box 2 by cooperating with the guide plate 3, the pressing plate 4, the guide block 12, the L-shaped rod 11 and the cylinder 8. The pressing plate 4 rotates to contact the corners of the cosmetic packaging box to flatten the sharp corners of the heat shrink film joint, so that the heat shrink film fits the packaging more closely. The structure is simple and the operation is convenient. It improves the packaging aesthetics while effectively controlling the investment cost of the equipment.
