Description

Technical Field

[0001] This utility model relates to the field of sealing and packaging equipment technology, and more specifically, it relates to a continuous packaging machine with a replaceable mechanism. Background Technology

[0002] Sealing packaging machines are commonly used in the food industry. They place food inside containers such as boxes and then heat-seal the opening with a packaging film to achieve airtight packaging and preservation. A sealing packaging machine includes an upper mold mechanism and a lower mold mechanism. The packaging container is placed on the lower mold, and the upper mold mechanism moves downwards to cut and heat-seal the packaging film at the opening of the container, completing the sealing process. Due to the diverse types of packaging containers, sealing different sizes of containers requires upper and lower mold mechanisms of corresponding sizes. However, in existing equipment, both the upper and lower mold mechanisms are fixedly mounted on the frame and cannot be disassembled or replaced, resulting in high equipment changeover costs and increased production costs. Based on these issues, this paper proposes a sealing packaging machine that facilitates mold replacement. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sealing and packaging machine with low changeover cost, wide applicability and easy mold replacement.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a continuous packaging machine with a replaceable mechanism, comprising a frame, wherein a detachably fitted upper mold mechanism and a lower mold mechanism are provided within the frame, a conveying mechanism is provided on one side of the lower mold mechanism, the conveying mechanism is provided with a guide rail structure with adjustable width, the upper mold mechanism includes an upper vacuum chamber with an upper cover plate, a slide rail is provided above the frame, the two sides of the upper cover plate are slidably fitted within the slide rail, a positioning structure for limiting the movement of the upper cover plate is also provided on the slide rail, and an assembly cavity for assembling the lower mold mechanism is provided below the frame.

[0005] The present invention is further configured such that: the positioning structure includes a positioning seat and a positioning bolt that is inserted into the positioning seat and slides up and down; the positioning seat is provided with a locking groove; and locking blocks are provided on both sides of the positioning bolt; when the locking blocks are inserted into the locking groove, the tail end of the positioning bolt extends out of the positioning seat and is fixedly inserted into the upper cover plate.

[0006] The present invention is further provided with two handles on the upper end surface of the upper cover plate.

[0007] The present invention is further configured such that: the guide rail structure includes at least two guide rails, a conveying area is formed between the two guide rails, a sliding member is provided on the guide rail, a transverse slide is provided on the bottom surface of the conveying mechanism, and the sliding member is inserted into the slide and slides in cooperation.

[0008] By adopting the above technical solution, rapid mold changeover is achieved. When changing molds of different specifications, there is no need to disassemble the main structure of the equipment. The changeover time is short and the efficiency is high. It has the advantage of high compatibility with multiple specifications. The upper mold mechanism and the frame are assembled by sliding rails, and the lower mold mechanism and the frame are assembled by placing them in the assembly cavity. The assembly method is simple and applicable to the replacement and assembly of molds of various specifications. It also has the advantages of low equipment cost, low maintenance cost, and low storage cost. Attached Figure Description

Detailed Implementation

[0016] Reference Figures 1 to 6 The embodiments of this utility model will be further described below.

[0017] A continuous packaging machine with a replaceable mechanism includes a frame 1. The frame 1 has a detachably fitted upper mold mechanism 2 and a lower mold mechanism 3. A conveying mechanism 4 is located on one side of the lower mold mechanism 3. The conveying mechanism 4 has an adjustable guide rail structure 40. The upper mold mechanism 2 includes an upper vacuum chamber with an upper cover plate 20. A slide rail 16 is provided above the frame 1. The two sides of the upper cover plate 20 are slidably fitted within the slide rail 16. A positioning structure 10 for restricting the movement of the upper cover plate 20 is also provided on the slide rail 16. An assembly cavity 11 for assembling the lower mold mechanism 3 is provided below the frame 1.

[0018] The positioning structure 10 includes a positioning seat 12 and a positioning bolt 13 that slides vertically within the positioning seat 12. The positioning seat 12 has a locking groove 14, and locking blocks 15 are provided on both sides of the positioning bolt 13. When the locking blocks 15 are inserted into the locking groove 14, the tail end of the positioning bolt 13 extends outside the positioning seat 12 and is fixed to the upper cover plate 20. The upper end face of the upper cover plate 20 has two handles 21.

[0019] The guide rail structure includes at least two guide rails 41, and a conveying area 42 is formed between the two guide rails 41. A sliding member 43 is provided on the guide rail 41, and a transverse slide rail 17 is provided on the bottom surface of the conveying mechanism 4. The sliding member 43 is inserted into the slide rail 17 for sliding engagement.

[0020] Working principle: When the equipment needs to be changed, by pulling up the positioning bolt 13, the locking block 15 disengages from the locking groove 14. At this time, the tail end of the positioning bolt 13 disengages from the upper cover plate 20 of the upper mold mechanism 2, and the upper cover plate 20 can then slide out of the frame 1 along the slide rail 16, realizing the disassembly and replacement of the upper mold mechanism 2. The lower mold mechanism 3 can be directly disassembled from the assembly cavity 11 in the frame 1, which is simple and convenient to operate. When adjusting the conveying area 42, the left and right displacement guide rail 41 is used to expand or shrink the conveying area 42, which is suitable for packaging containers of different specifications. When the guide rail 41 moves, it slides left and right along the horizontally set slide rail 17 through the sliding member 43, which is coordinated with the adjustment of the guide rail 41.

[0021] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
