Description

Technical Field

[0001] This utility model belongs to the field of vacuum packaging machine technology, and specifically relates to an energy-saving vacuum packaging machine and a heat-sealing structure. Background Technology

[0002] Vacuum packaging machines are devices that remove air from packaging and seal it to extend the shelf life of goods and prevent oxidation and mold growth. They are widely used in the food, pharmaceutical, and electronics industries. In operation, a vacuum packaging machine creates a vacuum by removing air from the packaging and then uses a heat-sealing structure to seal the opening. However, most commonly used vacuum packaging machines place the bags to be packaged flat in the vacuum chamber. This results in the bags occupying a significant amount of surface area. Furthermore, most commonly used vacuum packaging machines have a symmetrical structure with two heat-sealing structures, allowing multiple bags to be packaged simultaneously. However, this flat-lay structure requires more space, resulting in a wider machine. To vacuum-pack even more bags simultaneously, the width needs to be further increased, thus increasing the required production area.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content

[0008] In a preferred embodiment, an adjusting stud is threadedly connected to the inner side of the adjusting threaded hole. The lower end of the adjusting stud is rotatably connected to the support plate via a bearing. According to the specifications of the items after being packed in the packaging bag, the adjusting stud rotates and engages with the adjusting threaded hole, thereby driving the two sets of limiting plates to move back and forth to complete the spacing adjustment.

The heat sealing strip contains several groups of ceramic heating elements that are linearly and equally distributed. Each group of ceramic heating elements has an independently controlled structure. The open end of the packaging bag is placed in the heat sealing groove and held by the heat sealing strip. During heat sealing, several groups of ceramic heating elements are independently started and stopped according to the arrangement of the packaging bag, and the heat is reduced by the heat reflective layer to reduce heat loss to the non-heat-sealed area, thereby improving the heat sealing energy-saving effect.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are:

[0027] The vacuum tank 102 is provided in two sets and is arranged in a symmetrical structure. Each set of vacuum tank 102 has a space partition plate 114 fixedly connected to the middle position of the inner side. A support plate 104 is installed on both the front and rear sides of the space partition plate 114 inside the vacuum tank 102.

[0028] An adjustment assembly 200 is provided above the support plate 104. A set of electric telescopic rods 103 for adjusting the height of the support plate 104 is fixedly connected below the support plate 104. A sealing outer ring 105 for sealing is fixedly connected to the outside of the support plate 104. Two sets of symmetrically arranged limiting plates 201 are provided in the adjustment assembly 200.

[0029] A guide groove 106 for assisting the linear movement of the limiting plate 201 is provided in the middle of the upper surface of the support plate 104, and a guide slider 202 is fixedly connected below the limiting plate 201.

[0030] The guide slider 202 and the guide groove 106 are movably fitted together. An adjustment sleeve 205 is provided in the middle position between the front and rear sets of limit plates 201. The upper surface of the adjustment sleeve 205 is vertically penetrated to form an adjustment threaded hole.

[0031] An adjusting stud 206 is connected to the inner thread of the adjusting threaded hole. The lower end of the adjusting stud 206 is rotatably connected to the support plate 104 through a bearing. According to the specifications of the items after being packed in the packaging bag, the adjusting stud 206 is rotated and engages with the adjusting threaded hole, which drives the two sets of limit plates 201 to move back and forth to complete the spacing adjustment.

[0032] Two sets of symmetrically arranged rotating seats 203 are fixedly connected to the front and rear sides of the adjusting sleeve 205 and the end of the limiting plate 201 near the adjusting sleeve 205. A rotating connecting plate 204 is rotatably connected between the two sets of rotating seats 203.

[0033] Two sets of symmetrically distributed switching rods 113 are fixedly connected to the front and rear sides of the packaging base 101.

The switching rods 113 drive the vacuum cover 111 to switch left and right under the control of the motor rotation, and the vacuum sealing ring 112 and the packaging base 101 form a sealed vacuum structure.

[0034] Specifically, the user places the item to be packaged inside the packaging bag. According to its overall specifications, the electric telescopic rod 103 drives the support plate 104 to move up and down, and the sealing outer ring 105 seals against the inner wall of the vacuum groove 102 to form a sealing structure. According to the specifications of the packaging bag, the adjusting stud 206 can be rotated and cooperate with the adjusting threaded hole to drive the two sets of limiting plates 201 to move back and forth to complete the spacing adjustment. The guide slider 202 assists in linear adjustment along the guide groove 106, so that the adjusted support plate 104 and limiting plate 201 limit and support the packaging bag, and place the upper end of the packaging bag in the heat sealing groove 108. The vertically placed packaging bag avoids the large width area occupied by the flat structure, thus reducing the overall width when packaging multiple sets at the same time.

[0035] Please see Figures 1-3 As a second embodiment of this utility model:

[0036] Four sets of heat-sealing seats 107 are fixedly connected to both the left and right ends of the upper surface of the packaging seat 101. A heat-sealing groove 108 is opened on the upper surface of the heat-sealing seat 107. A heat-reflective layer 109 for improving the heat-sealing effect is fixedly connected to the inner side of the heat-sealing groove 108.

[0037] The heat reflective layer 109 is made of polished aluminum foil. A heat sealing strip 110 is provided above the heat sealing seat 107. The heat sealing strip 110 contains several groups of ceramic heating elements that are linearly and equally distributed. Each group of ceramic heating elements has an independent control structure. The open end of the packaging bag is placed in the heat sealing groove 108 and pressed by the heat sealing strip 110. During heat sealing, several groups of ceramic heating elements are independently started and stopped according to the arrangement of the packaging bag, and the heat is reduced to the non-heat-sealed area by passing through the heat reflective layer 109.

[0038] Based on the first embodiment described above, further, the user places the open end of the packaging bag into the heat-sealing groove 108 and holds it with the heat-sealing strip 110. During the heat sealing process, several sets of ceramic heating elements are independently started and stopped according to the arrangement of the packaging bag, and the heat is reduced to the non-heat-sealed area by passing through the heat reflection layer 109, thereby improving the heat sealing energy-saving effect.
