Description

Technical Field

[0001] This utility model relates to the field of vacuum packaging equipment, and more specifically, it relates to an electric cross-cutting and sealing packaging machine. Background Technology

[0002] Currently, most mainstream food storage containers on the market use a ring-cut heat-sealing process (i.e., continuous circumferential cutting and sealing). This technology uses a ring-shaped heated blade to continuously heat-press and cut the film at the container opening in a circumferential direction, forming a sealing layer. A typical application is the sealing of PP / PE material food storage containers, which requires ensuring airtightness to extend the shelf life of food. However, existing ring-cut heat-sealing technology has the following problems: ring-cutting of the packaging film produces ring-shaped waste strips, requiring the addition of a winding structure to collect these waste strips on the equipment, resulting in a non-compact overall structure and large space occupation; its applicability is limited, as the ring die needs to be changed according to the shape of the packaging box. For some irregularly shaped packaging boxes, such as rectangular or elliptical boxes, a custom-made ring die is required to ring-cut the packaging film, resulting in high changeover costs and high production costs. Based on the above problems, this application proposes an electric cross-cutting sealing packaging machine with a wide range of applications, a simple and compact overall structure, small space occupation, rapid packaging capability, and high working efficiency. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an electric cross-cutting and sealing packaging machine with a wide range of applications and high working efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an electric cross-cutting sealing and packaging machine, comprising a frame, a sealing mold assembly, a film roll assembly, and a pallet frame assembly, wherein the sealing mold assembly is located between the film roll assembly and the pallet frame assembly, and a cutter assembly is provided at the front end of the sealing mold assembly. The frame is provided with a slide rail that slides with the pallet frame assembly, and the pallet frame assembly moves back and forth along the slide rail toward the lower part of the sealing mold assembly. The pallet frame assembly is provided with a positioning part for fixing the packaging film. After the packaging film on the film roll assembly passes around the cutter assembly, it is fixed in the positioning part of the pallet frame assembly. The positioning part moves the packaging film to the lower part of the sealing mold assembly, and the packaging film is positioned between the sealing mold assembly and the pallet frame assembly.

[0005] The present invention is further configured such that: one end of the tray frame assembly is provided with a magnetic strip, the positioning part includes a positioning cross plate that is slidably engaged on the slide rail, the positioning cross plate is provided with at least one magnetic block, and the packaging film is sandwiched between the magnetic strip and the magnetic block.

[0006] The present invention is further provided that: a handle is provided at the other end of the tray frame assembly.

[0007] The present invention is further configured such that the positioning plate is provided with three magnetic blocks.

[0008] The present invention is further configured such that: the cutting blade assembly includes a blade and an L-shaped blade guard plate; the side of the blade end is fixed to the sealing mold assembly; one end of the blade guard plate is fixed to the sealing mold assembly and abuts against the end of the blade; and the other end is bent and arranged parallel to the blade.

[0009] By adopting the above technical solutions, the cross-cut sealing method can avoid the traditional ring-cutting method, avoid the generation of ring-shaped waste strips, and eliminate the need for a waste winding mechanism, making the equipment structure simpler and more compact, and reducing the risk of mechanical failure. The straight-line cross-cut sealing technology eliminates the need to customize special ring-shaped die for different shapes (such as rectangular, elliptical and other irregular boxes), and only requires adjusting the cutter stroke to adapt to various box types, which has the advantage of wide applicability.

[0015] Reference Figures 1 to 4 The embodiments of this utility model will be further described below.

[0016] An electric cross-cutting sealing and packaging machine includes a frame 1, a sealing mold assembly 2, a film roll assembly 3, and a pallet frame assembly 4. The sealing mold assembly 2 is located between the film roll assembly 3 and the pallet frame assembly 4. A cutter assembly 5 is also provided at the front end of the sealing mold assembly 2. The frame 1 is provided with a slide rail 10 that slides with the pallet frame assembly 4. The pallet frame assembly 4 moves back and forth along the slide rail 10 toward the lower part of the sealing mold assembly 2. The pallet frame assembly 4 is provided with a positioning part for fixing the packaging film. After the packaging film on the film roll assembly 3 passes around the cutter assembly 5, it is fixed in the positioning part of the pallet frame assembly 4. The positioning part moves the packaging film to the lower part of the sealing mold assembly 2, and the packaging film is in a state between the sealing mold assembly 2 and the pallet frame assembly 4.

[0017] One end of the pallet rack assembly 4 is provided with a magnetic strip 40. The positioning part includes a positioning horizontal plate 41 that slides on the slide rail 10. The positioning horizontal plate 41 is provided with at least one magnetic block 42, and the packaging film is sandwiched between the magnetic strip 40 and the magnetic block 42. The other end of the pallet rack assembly 4 is provided with a handle 43. The positioning horizontal plate 41 is provided with three magnetic blocks 42.

[0018] The cutting blade assembly 5 includes a blade 51 and an L-shaped blade guard 50. The side of the end of the blade 51 is fixed to the sealing mold assembly 2. One end of the blade guard 50 is fixed to the sealing mold assembly 2 and abuts against the end of the blade 51. The other end is bent and set parallel to the blade 51.

[0019] Working principle: The packaging box to be sealed is placed in the pallet frame assembly 4. The packaging film roll assembly 3 is pulled down and wrapped around the cutter assembly 5. Through the mutual attraction of the magnetic strip 40 and the magnetic block 42, the end of the packaging film is clamped between the positioning plate 41 and the pallet frame assembly 4. Then, the pallet frame assembly 4 is pushed so that it moves along the slide rail 10 to the bottom of the sealing mold assembly 2. At the same time, the packaging film is moved between the pallet frame assembly 4 and the sealing mold assembly 2. Through the downward movement of the sealing mold assembly 2, the packaging box is heat-sealed. The blade 51 of the cutter assembly 5 also moves down with the sealing mold assembly 2, which plays the role of cutting the packaging film horizontally. After the heat-sealing packaging is completed, the handle 43 is placed on the pallet frame assembly 4, so that it moves away from the sealing mold assembly 2, and the unloading process is completed.
