Description

Technical Field

[0001] The utility model relates to the technical field of automated production, in particular to the technical field of fully automatic lamp packaging equipment. Background Art

[0002] At present, plastic sealing is used in the packaging of lamps, which significantly improves the protection effect and aesthetics of the products. However, the application of plastic sealing technology in lamp packaging also has certain technical difficulties due to the fragility of lamps.

[0003] First of all, although commonly used mold sealing, vacuum sealing and other technologies can perform precision sealing, their cost-effectiveness is low when applied to lamps and lanterns, and they are not suitable for lamp products with a variety of shapes.

[0004] Conventional heat shrink film roll-type plastic sealing with one end pre-sealed has the advantages of high efficiency and economy. However, when plastic sealing lamps with plastic shells, the nodes of the heat seal are not accurately grasped, and the appearance of plastic lamps will be damaged. Utility Model Content

[0005] In order to solve the above problems, the utility model proposes a fully automatic lamp packaging device, which aims to at least solve the problem of grasping the accuracy of the heat-sealing nodes as mentioned above and provide efficient packaging equipment.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A fully automatic lamp packaging device, comprising a first conveyor belt for conveying products, an unwinding device arranged on the side of the first conveyor belt for outputting heat shrinkable film, and a film separation device for layering the heat shrinkable film output by the unwinding device on the upper and lower ends of the first conveyor belt;

[0008] It also includes a second conveyor belt that is staggered with the first conveyor belt toward the unwinding device, the second conveyor belt is provided with a first film cutting device for heat-sealing and cutting a heat shrink film in the product conveying direction, a second film cutting device for heat-sealing a side heat shrink film and cutting a residual film is provided on the opposite side of the unwinding device of the second conveyor belt, and a film rolling machine for recovering the residual film is provided at the rear end of the second film cutting device;

[0009] It also includes a third conveyor belt which is linearly connected with the second conveyor belt, and the third conveyor belt is provided with a heat shrink tunnel.

[0010] Compared with the prior art, in this case, the first conveyor belt with an unwinding device and the second conveyor belt with a film cutting device are staggered, and the unwinding device and the second film cutting device for cutting the residual film are arranged on both sides of the conveyor belt. The unwinding can be achieved by recovering the power of the film rolling machine that produces the residual film, and the film can be cut as much as it is unwound, so the sealing rhythm can be controlled efficiently and accurately.

[0011] In a preferred embodiment, the film winding machine is arranged at the lower end of the second conveyor belt, which can provide more stable tensile stress for the heat-shrinkable film moving back and forth.

[0012] In a preferred embodiment, the unwinding device includes a support roller for supporting the heat-shrinkable film roll. The support roller is arranged at the upper end of the first conveyor belt, and by using the self-weight of the heat-shrinkable film, it can automatically droop for easy pulling.

[0013] In some embodiments, the unwinding device further includes a plurality of guide rods arranged at the lower end of the support roller to keep the heat-shrinkable film under tension.

[0014] In some embodiments, the film separating device includes an upper reversing plate arranged at the upper end of the first conveyor belt and a lower reversing plate arranged at the lower end of the first conveyor belt.

[0015] In a preferred embodiment, an L-shaped film supporting rod is further included and arranged between the upper reversing plate and the first conveyor belt.

[0016] In a preferred embodiment, a guide plate is further included and arranged between the lower reversing plate and the first conveyor belt.

[0017] In some embodiments, a blowing device for blowing air between the film supporting rod and the first conveyor belt is further included.

[0018] In some embodiments, an adjusting rod for adjusting the heights of the upper reversing plate and the lower reversing plate is further included.

[0019] In a preferred embodiment, the first conveyor belt and the second conveyor belt are provided with support plates. Description of the Drawings

[0025] The features of the present invention and other related features are further described in detail below through embodiments for the understanding of those skilled in the same industry:

[0026] It should be noted that the words "upper", "lower", "left", and "right" used in the following description refer to the positional relationship in the spatial range. "Inner" and "outer" are also used to refer to the direction toward or away from the geometric center of a specific component. Figure 1 The "front" and "back" here refer to the direction in which the product moves on the equipment. The "front" direction is the direction in which the product enters, and the "back" direction is the direction in which the product exits.

[0027] Please refer to Figure 1 The fully automatic lamp packaging equipment in this case is a device for plastic sealing lamp products. The L1 section in the figure is the position of the first conveyor belt 1. A unwinding device 2 for outputting heat shrink film is arranged on the side of the first conveyor belt 1. At this time, the unwinding device 2 is located on the right side of the figure. It also includes a film separation device 3 for layering the heat shrink film output by the unwinding device 2 at the upper and lower ends of the first conveyor belt 1.

[0028] Furthermore, the L2 section in the figure is the position of the second conveyor belt 4, and the second conveyor belt 4 and the first conveyor belt 1 are staggered, and the direction is staggered toward the unwinding device 2, that is, the second conveyor belt 4 is arranged on the right side relative to the first conveyor belt 1. The second conveyor belt 4 is provided with a first film cutting device 41 for heat sealing and cutting the heat shrink film in the product conveying direction.

[0029] At this time, because the second conveyor belt 4 and the first conveyor belt 1 are staggered, there will be multiple extra heat shrink films on the left side of the second conveyor belt 4. A second film cutting device 42 for heat-sealing the side heat shrink film and cutting the residual film is set at this position, that is, on the side opposite to the unwinding device 2, and a film winding machine 43 for recovering the residual film is set at the rear end of the second film cutting device 42.

[0030] In this way, the unwinding device 2 and the second film cutting device 42 are arranged on both sides of the conveyor belt, that is, on both sides of the heat shrink film, respectively, so that the heat shrink film can be further stretched, and the unwinding can be achieved by recovering the power of the film winding machine 43 that produces residual film, and the amount of unwinding is cut, and the sealing rhythm can be controlled efficiently and accurately. In a preferred embodiment, the film winding machine 43 is arranged at the lower end of the second conveyor belt 4, which can provide a more stable tensile stress for the heat shrink film moving forward and backward.

[0031] In this way, after the mold opening and film coating, the film enters the third conveyor belt 5 in section L3 in the figure, and the third conveyor belt is provided with a heat shrink tunnel 51.

[0032] The heat sealing and cutting equipment for heat shrinkable films generally uses heating rods or heating plates to heat the parts to be sealed of the heat shrinkable film to the melting temperature, and then applies pressure through cylinders or springs to press the melted edges together. After maintaining for a certain period of time, it cools and solidifies to form a firm seal. For cutting, photoelectric sensors or encoders are used to detect the position of the heat shrinkable film, determine the cutting point, and the motor drives the cutting knife to precisely cut the heat shrinkable film into the required length, and then drying and heat shrinking are carried out. The heat sealing, cutting, and heat shrinking devices are common technical means in the industry and are not specifically limited in this case.

[0033] The heat shrinkable film involved in this case is a double-layer heat shrinkable film with one end of the heat shrinkable film roll pre-sealed, that is, a conventional heat shrinkable film roll with one end sealed. This is relatively common in the field of books with the same shape and simple styling. However, when used in the field of lamps with complex styling, a prerequisite for accurate cutting is to support and separate the two layers of heat shrinkable film so that the lamp can be accurately placed. Therefore, it is necessary to do a good job in unwinding and layering.

[0034] Please refer to Figure 2 and Figure 4 , the unwinding device 2 includes a supporting roller 22 for supporting the heat shrinkable film roll 21. At this time, the supporting roller 22 is arranged at the upper end of the first conveyor belt 1, and using the self-weight of the heat shrinkable film, it automatically sags for easy pulling. In some embodiments, guide rollers for flattening can also be added, which are not specifically limited in this case.

[0035] In some embodiments, the unwinding device 2 further includes a plurality of guide rods 23 arranged at the lower end of the supporting roller 22. The diameter, position, and quantity of the guide rods 23 can be adjusted according to requirements, mainly to keep the heat shrinkable film under tension.

[0036] Please refer to Figure 2 and Figure 3 , the film separating device 3 includes an upper reversing plate 31 arranged at the upper end of the first conveyor belt 1 and a lower reversing plate 32 arranged at the lower end of the first conveyor belt 1. The function of the reversing plate is to move the vertically downward heat shrinkable film in the front-back direction. Since the heat shrinkable film in this case is in a pre-heat-sealed state at one end, there is a film passing gap 33 between the unwinding device 2 and the first conveyor belt 1.

[0037] As a device for separating the heat shrinkable film, an L-shaped film supporting rod 34 is arranged between the upper reversing plate 31 and the first conveyor belt 1. Please refer to Figure 3 , a blowing device 6 for blowing air is further arranged on the first conveyor belt 1 between the film supporting rod 34 and the first conveyor belt 1.

[0038] Please refer to Figure 3, a guide plate 35 is provided between the lower reversing plate 32 and the first conveyor belt 1. The main function of the guide plate 35 is to prevent the heat-shrinkable film from being rolled into the first conveyor belt 1. In some embodiments, an adjusting rod 36 for adjusting the heights of the upper reversing plate 31 and the lower reversing plate 32 is further included.

[0039] Please refer to Figure 5 , the first conveyor belt 1 and the second conveyor belt 2 in this case can both adopt the pulley transmission mode. When adopting the pulley transmission mode, a support plate 11 can be added to prevent the belt from fatigue when the lighting product is too heavy or the conveying distance is long.

[0040] As described above, this case protects a fully automatic lighting packaging device, and all technical solutions identical or similar to this case should be regarded as falling within the protection scope of this case.
