Description

Technical Field

[0001] The utility model relates to the technical field of packaging devices, in particular to an automatic sealing and heat shrinking packaging device. Background Art

[0002] The automatic sealing and heat shrink packaging device places the items to be packaged on the working platform of the packaging machine and transports the items to the position for sealing and cutting the heat shrink film. The device will automatically wrap the heat shrink film around the outside of the items and perform the sealing and cutting operations. After the sealing and cutting is completed, the sealed and cut items and the film are sent to the heat shrink chamber for heating treatment, so that the heat shrink film shrinks and fits tightly to the surface of the items, thereby achieving sealing, packaging and protection of the items.

[0003] When using a sealing and heat shrink packaging device, when the items in the package box are output through the heating chamber, other conveying equipment is usually placed at the output end of the heating chamber to centrally convey the items in the package box. However, since the height position of the output end of the heating chamber is fixed, if the height of the conveying equipment is much lower than the output end of the heating chamber, the packaging film and the internal contents of the package box may be damaged during the falling of the items in the package box. Utility Model Content

[0011] Preferably, one end of the guide plate is fixedly connected to a pad rod, and the top end of the pad rod is an inclined surface.

[0012] The effect achieved by the above components is that when the packaging box enters the surface of the sliding plate from the surface of the guide plate, it will slide downward on the inclined surface of the top end of the pad rod, thereby preventing the packaging box from rolling when entering the sliding plate as much as possible.

[0013] Preferably, a control panel is provided at the top of the heat sealing machine, a protective device is provided on one side of the control panel, the protective device includes two sliders, two slide grooves are provided on one side of the control panel, the outer surface of the slider slides on the inner wall of the slide groove, and a baffle is fixedly connected to one side of the slider.

[0015] Preferably, a plurality of protrusions are fixedly connected to one side of the baffle, and the protrusions are linearly distributed on one side of the baffle.

[0016] The effect achieved by the above components is that the baffle can be pushed more conveniently by pressing the protrusion on the outer surface of the baffle with the hand to control the movement of the baffle and adjust the position of the baffle.

[0017] Preferably, a magnetic strip is fixedly connected to one side of the baffle, and an iron block is fixedly connected to one side of the control panel.

[0018] The effect achieved by the above components is that when the baffle is pushed to cover the control button, the magnetic strip at one end of the baffle will contact and magnetically attract the outer surface of the iron block, thereby fixing the position of the baffle.

[0019] Preferably, a plurality of rectangular grooves are formed on the outer surface of the baffle, and a plurality of sliding rods are slidably connected to the inner wall of the baffle.

[0020] The effect achieved by the above components is: when the baffle covers the control button, pushing a single sliding rod to move can control the sliding rod to open or close a single rectangular slot, operate a single row of control buttons, and avoid accidentally touching other control buttons when operating the control button as much as possible.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are:

[0022] In the utility model, by arranging an adjustment device, when the conveying device is placed at one end of the heat sealing machine, the height position of the sliding plate is changed by rotating the threaded cylinder so that the bottom end of the sliding plate is as close to the conveying device as possible, so that the packaging box can slide from the surface of the guide plate and the sliding plate to the conveying device, and the problem of damage to the packaging film or contents due to the packaging box falling from an excessively high height can be avoided as much as possible.
