Description

Technical Field

[0001] The utility model relates to the technical field of material packaging tools, and in particular provides a material heat shrink packaging mechanism. Background Art

[0002] Heat shrinking is a common way to package materials. Heat shrinking is to heat and shrink the heat shrink packaging film by blowing out hot air from a hot air gun to form a package for the material. The common operation method is to use a handheld hot air gun to manually shrink the package, that is, the operator uses a manual hot air gun to move the hot air gun muzzle to shrink the location to be shrunk, so the technical requirements for the operator are relatively strict. At the same time, the diameter and thickness of the objects to be shrunk are different. The air gun needs to be preheated in advance during the operation. Only when the temperature is reached can the shrunk product be operated. The control of temperature and time requires certain technical capabilities. The hot air gun is a heating device, and the exposed heating head and the hot air outlet that blows air all the time are more unfavorable to safety, which is easy to cause burns or burn other objects and cause fires. Therefore, while taking up personnel time, safety cannot be guaranteed. Personnel cannot get actual efficiency work, which also buries hidden dangers for enterprise safety production.

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0017] refer to Figure 1-Figure 4The utility model provides a material heat shrink packaging mechanism, including a slide bar lifting drive unit 1, two slide bars 2, an arc slide 3 and two hot air guns 4. The slide bar lifting drive unit 1 is vertically fixedly arranged below the material placement station, the slide bar lifting drive unit 1 is rotatably connected to one end of the two slide bars 2, the arc slide 3 is fixedly arranged below the material placement station on one side of the slide bar lifting drive unit 1, two groups of connecting components are arranged in the slide groove of the arc slide 3, the other ends of the two slide bars 2 are respectively rotatably connected to one group of connecting components, and the other sides of the two groups of connecting components are respectively connected to a hot air gun 4.

[0018] The utility model is arranged on a heat shrink packaging device. When the utility model is used to perform heat shrink packaging on materials, the materials are placed at the material placement station of the heat shrink packaging device, and the slide bar lifting drive unit 1 drives one end of two slide bars 2 to perform up and down lifting movements, and the other ends of the two slide bars 2 pull the connecting components to perform circular movements on both sides of the slide groove of the arc slide 3, and the two groups of connecting components drive the two hot air guns 4 to perform circular movements, thereby achieving heating and blowing of the positions where the materials need to be heat shrunk.

[0019] When the material is cylindrical, the cylindrical material can be driven to rotate under the action of the material rotation drive assembly, so as to achieve the blowing and shrinking of the heat shrink film of the entire circumference of the cylindrical material. At the same time, in order to blow and shrink different positions in sequence, the drive of the slide bar lifting drive unit 1 to the slide bar 2 can be set, first let the two hot air guns 4 cyclically blow and shrink the heat shrink film on both sides of the cylindrical material at the positions on both sides, and then cyclically blow and shrink on both sides of the middle position, and finally achieve overall heat shrinkage in coordination with the rotation of the material.

[0020] As a specific implementation method of the connecting component, each group of the connecting components includes a connecting plate 5, two connecting wheels 6 and a tension spring 7. The connecting plate 5 is fixedly connected to the hot air gun 4. Two connecting wheels 6 are arranged on the connecting plate 5.

A tension spring 7 is arranged between the end of the slide rod 2 away from the slide rod lifting drive unit 1 and the lower end of the connecting plate 5. The tension spring 7 keeps the hot air gun 4 in a state of being inclined toward the center direction of the arc slide 3.

[0021] During the movement of the slide bar 2 pulling the hot air gun 4, the slide bar 2 pulls the connecting wheel 6 connected in the slide groove of the arc slide 3 to move along the slide groove, and pulls the connecting wheel 6 connected to the lower edge of the arc slide 3 to move along the lower edge of the arc slide 3. At the same time, the lower end of the hot air gun 4 is pulled up by the pulling of the tension spring 7, so that the hot air gun 4 remains in a state of being inclined toward the center direction of the arc slide 3, which is beneficial to the hot air blowing and shrinking of the material surface.

[0023] Preferably, the slide bar lifting drive unit 1 is a linear module, on which a driving slider 10 is arranged, and the driving slider 10 is rotatably connected to one end of the two slide bars 2 .

The first lifting control sensor unit 11 transmits the signal to the controller, and the controller controls the linear module to stop driving or drive in the opposite direction.
