Description

Technical Field

[0001] The utility model relates to the technical field of foam film sticking machines, in particular to a home appliance protective foam film sticking machine. Background Art

[0002] Foam is a solid plastic with micropores. It has the characteristics of light weight, thermal insulation and shock absorption. It is usually used to package products. In the process of packaging home appliances, it is necessary to ensure the waterproofness of the packaging box, so a laminating machine is needed to cover a layer of film on the outer surface of the foam.

[0003] The laminating machine is a special equipment used to laminate materials. It mainly includes a conveying mechanism and a laminating mechanism. The protective foam is placed on the conveying table and transported along the conveyor belt. After reaching the designated position, the driving mechanism pushes the film frame down to coat the foam.

[0004] After the film is covered on the outer surface of the foam, it needs to ensure that it fits tightly with the foam. However, the tensile tension of the film during the lamination process is low, which may cause wrinkles or stacking after lamination, resulting in a loose fit between the film and the foam, which is easily damaged by external forces.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] The flattening assembly 4 includes an electric push rod 401 fixedly connected to the upper surface of the support frame 1, a center rod 402 is provided at the driving end of the electric push rod 401, both ends of the center rod 402 are movably connected to round rods 403, one end of the round rod 403 away from the center rod 402 is fixedly connected to a rotating rod 404, and one end of the rotating rod 404 away from the round rod 403 is movably connected to a flattening roller 405;

[0027] Specifically, both ends of the center rod 402 are fixedly connected with an axle rod 407, one end of the round rod 403 close to the center rod 402 is provided with a groove 408, one end of the axle rod 407 away from the center rod 402 is movably connected to the inner wall of the groove 408, a torsion spring 409 is sleeved on the outer surface of the axle rod 407, one end of the torsion spring 409 is fixedly connected to the outer surface of the axle rod 407, and the other end of the torsion spring 409 is fixedly connected to the inner wall of the groove 408, and the flattening roller 405 is arranged in the middle part just above the laminating frame 5, and the angle of the flattening roller 405 is thirty degrees;

[0028] Furthermore, the electric push rod 401 is started to push the center rod 402 downward, and the flattening roller 405 moves downward to push the film to contact the outer surface of the foam. As the electric push rod 401 continues to push, the flattening roller 405 rotates around the shaft 407 and squeezes the torsion spring 409. The flattening roller 405 rolls to both sides to push and flatten the film, so that the film fits tightly to the outer surface of the foam. When the electric push rod 401 stretches the center rod 402 upward, the flattening roller 405 rises and the torsion spring 409 stretches to pull it to rotate and reset.

[0029] Example 2

[0030] Reference Figure 1 , Figure 2 and Figure 4 , which is the second embodiment of the utility model, this embodiment is based on the previous embodiment, and a deflection assembly 6 is provided on the upper surface of the support frame 1;

[0031] The deflection assembly 6 includes a motor 601 fixedly connected to the support frame 1 plate, the driving end of the motor 601 is fixedly connected to the first gear 602, the driving end of the electric push rod 401 is movably connected to the second gear 603, and the upper surface of the second gear 603 is fixedly connected to the damping shaft 406;

[0032] Specifically, the first gear 602 and the second gear 603 are meshed with each other, and the top end of the damping shaft 406 is fixedly connected to the driving end of the electric push rod 401;

[0033] Furthermore, after the flattening roller 405 flattens the film laterally, the flattening component 4 will reset, and then the motor 601 will be started. The driving end of the motor 601 drives the first gear 602 to rotate. While the first gear 602 rotates, it engages and drives the second gear 603 to rotate, which in turn drives the flattening roller 405 to rotate ninety degrees, so as to facilitate the longitudinal flattening of the film. The second gear 603 and the electric push rod 401 are connected by a damping shaft 406 to prevent the second gear 603 from rotating. The second gear 603 and the center rod 402 are fixedly connected by weldments, thereby achieving the effect of comprehensively flattening the film, making the film fit closely to the foam, thereby improving the waterproof protection of home appliances.

[0034] Working principle: When the device is in use, the foam is placed on the conveying table and will be conveyed to the bottom of the film coating frame 5, and then the driving mechanism 3 pushes the film coating frame 5 to press down to coat the foam. Since the specific structure and working principle of the device are existing technologies well known to the staff in this field, they will not be elaborated here. Before the film covers the outer surface of the foam, the electric push rod 401 is started to push the center rod 402 to move downward, and the flattening roller 405 moves downward to push the film to contact the outer surface of the foam. With the continuous pushing of the electric push rod 401, the flattening roller 405 will rotate around the shaft 407 and squeeze the torsion spring 409. The flattening roller 405 rolls to both sides to push and flatten the film, so that the film is tightly attached to the outer surface of the foam. When the electric push rod 401 stretches the center rod 402 upward, the flattening roller 405 rises and the torsion spring 409 stretches to pull it to rotate and reset;

[0035] After the flattening roller 405 flattens the film horizontally, the flattening component 4 will reset, and then the motor 601 will be started. The driving end of the motor 601 drives the first gear 602 to rotate. While the first gear 602 rotates, it engages and drives the second gear 603 to rotate, which in turn drives the flattening roller 405 to rotate ninety degrees, so as to facilitate the longitudinal flattening of the film. The second gear 603 and the electric push rod 401 are connected by a damping shaft 406 to prevent the second gear 603 from rotating, thereby achieving the effect of comprehensively flattening the film, making the film fit closely to the foam, and improving the waterproof protection of home appliances.
