Description

[Detailed description of the invention] (Industrial field of application) The present invention is designed to vacuum the inside of a plastic film packaging bag used for food storage, etc., and then This invention relates to a tabletop vacuum packer that forms two welded parts.

(Prior art and problems) As shown in Fig. 3, the tabletop vacuum packer has a heat insulating structure on the top surface of the main body 1 which houses equipment (intake fan motor, transformer, micro switch, etc. - not shown). A packaging bag welding heater 3 and a fusing heater 4 are arranged in parallel with each other via a material 2, and
A flat intake cylinder 5 having an intake port 5a at the center of the upper surface is attached so as to be able to move vertically, and a band-shaped elastic body 7 ( A band-shaped elastic body 8 (made of sponge or the like) for sealing the opening of the packaging bag is attached, which has a recess 8a that fits into the upper surface of the tip of the suction pipe 5 (made of heat-resistant rubber or the like).

Then, the opening of the packaging bag containing the food is inserted into the suction tube 5 and placed on the top surface of the main body 1, the lid 6 is closed, and the opening of the packaging bag is pressed and sealed by the elastic body 8. , the suction fan motor is operated to suction the air inside the packaging bag from the suction pipe 5 to create a vacuum state.

Next, the welding heater 3 is energized to linearly weld the opening of the packaging bag, and then the fusing heater 4 is energized to fuse it.

As described above, in the conventional desktop vacuum packer, a single welded part is formed at the opening of the packaging bag, but sometimes two parallel welded parts are formed in order to improve the maintenance of the vacuum state.

In such a case, in the conventional desktop vacuum packer, after forming a single welded part, the lid 6 is opened, the packaging bag is moved toward the front, the lid 6 is closed again, and the welding heater 3 is energized. This resulted in the formation of a second welded part, which resulted in the defect of poor work efficiency.

In addition, since heaters for welding and for fusing have different calorific values, it is troublesome in terms of parts management.

(Means for Solving the Problems) The present invention provides a heater on the top surface of a main body housing equipment inside through a heat insulating material, a suction cylinder movable up and down in the center of the top surface of the main body, and a lid. In the vacuum pack, which includes an elastic body for pressing the packaging bag onto the heater and an elastic body for pressing the opening of the packaging bag against the top surface of the body on the inner surface of the body, two heaters are arranged in parallel on the heat insulating material. Support arms supporting both ends of a heat-resistant membrane provided with a width that simultaneously covers the two heaters are slid onto the upper surface of the main body perpendicular to the longitudinal direction of the heaters to simultaneously cover the two heaters, or The present invention is provided with a guide device that selectively covers only one heater.

(Example) Embodiments of the present invention will be described with reference to the drawings.

The difference between the present invention and the conventional desktop vacuum packer shown in FIG. Attach the same symbol.

As shown in FIG. 1, a heater 4 having the same calorific value as a conventional fusing heater 4 is arranged in parallel on the upper surface of the main body 1 with a heat insulating material 2 interposed therebetween.

Reference numeral 9 denotes a heat-resistant film (approximately 0.13 mm thick) made of polytetrafluoroethylene resin or the like having a width that simultaneously covers the tops of the two heaters 4, and support arms 10 are attached to both ends of the heat-resistant film 9. ing.

Thus, a groove 10 is formed on the lower end surface of each support arm 10.
a is formed, and a protrusion 11 that loosely fits into the groove 10a extends over a length 1.5 times the width of the heat-resistant film 9 (support arm 10) in the recess 1a on both sides of the upper surface of the main body 1 (two heaters). The heat-resistant film 9 slides through the support arm 10 using the protrusion 11 of the main body 1 as a guide, and covers the two heaters 4 at the same time. You can also cover only books.

Therefore, when forming two welded parts parallel to the opening of the packaging bag, the heat-resistant film 9 is slid to cover the two heaters 4 at the same time.
If you place the opening of the packaging bag on top (see Figure 2 A),
Through the interposition of the heat-resistant film 9, an amount of heat suitable for welding is supplied, and two welded portions are simultaneously formed.

Further, when forming and fusing a single welded part normally, it is sufficient to slide the heat-resistant film 9 forward to cover only one heater 4 (see FIG. 2B).

(effect) The present invention has the following effects.

(a) By moving the heat-resistant film, two welded parts can be formed at the opening of the packaging bag at the same time, and normal welding and fusing are also possible, making it extremely convenient to use.

(b) Since it is sufficient to use two heaters for fusing, parts management in the manufacturing process of the tabletop vacuum packer is also easy.
