Description

Technical Field

[0001] This invention belongs to the field of mechanical technology and relates to a vacuum packaging machine with an adjustable table width. Background Technology

[0002] Vacuum packaging machines automatically remove air from packaging bags, achieving a predetermined vacuum level before sealing. Alternatively, nitrogen or other mixed gases can be added before sealing. Before chips leave the factory, chip tubes need to be placed in packaging bags, vacuumed, and then packaged.

[0003] Existing vacuum packaging machines use a fixed table length, which is not suitable for packaging chip tubes of different lengths and the packaging efficiency is relatively low. Therefore, it is necessary to design a vacuum packaging machine with an adjustable table width. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a vacuum packaging machine with an adjustable table width.

[0005] The objective of this invention can be achieved through the following technical solution: A vacuum packaging machine with an adjustable table width, comprising a frame, on which a vacuum packaging machine body is mounted, characterized in that it further comprises two placement platforms, a worktable mounted on the frame, an adjustment belt provided on the worktable, a first track and a second track horizontally fixed on the worktable, a slider first slidably connected to the first track, the slider first being connected to one of the placement platforms, the placement platform being connected to the adjustment belt via a connecting piece first; a slider second slidably connected to the second track, the slider second being connected to an auxiliary platform, the auxiliary platform being connected to the adjustment belt via a connecting piece second, a guide sleeve fixed on the auxiliary platform, a guide rod vertically mounted on the guide sleeve, the guide rod being connected to the other placement platform, the placement platform also being connected to the upper end of a connecting rod; a guide plate vertically fixed on the worktable, the guide plate having a U-shaped clearance guide groove, a roller being provided in the U-shaped clearance guide groove, the roller also being connected to the lower end of a connecting rod; a widened platform is slidably connected to both placement platforms via an auxiliary rod.

[0006] The widened platform has two handles connected to it, and a limiting part is formed between the two handles.

[0007] A lower sealing strip is horizontally mounted on the frame, and an electric heating strip is provided on the lower sealing strip. The vacuum packaging machine body has a swingable swing arm, and a mounting base is mounted on the swing arm. A guide block is fixed on the mounting base, and a guide post is slidably connected to the guide block. A spring is also provided between the guide block and the guide post. An upper sealing strip that cooperates with the lower sealing strip is horizontally connected to the guide post. The frame is also equipped with a horizontally retractable vacuum extraction pipe, which can extend between the upper and lower sealing strips.

[0008] An electric push rod is mounted on the frame, and the push rod of the electric push rod is set horizontally. The end of the push rod is connected to a vacuum pumping pipe through a connecting frame.

[0009] The upper sealing strip is also provided with a semi-circular groove for the vacuum pumping pipe to pass through. The lower sealing strip is horizontally movable with an adjustment shaft.

Detailed Implementation

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] like Figures 1-9As shown, this adjustable-width vacuum packaging machine includes a frame 1, on which a vacuum packaging machine body 2 is mounted. In this embodiment, the vacuum packaging machine body 2 adopts an existing structure, which allows the vacuum extraction pipe 22 to be in a vacuum. It also includes two placement platforms 5. A worktable 4 is mounted on the frame 1, and an adjustment belt 24 is provided on the worktable 4. A first track 7 and a second track 9 are horizontally fixed on the worktable 4. A slider 6 is slidably connected to the first track 7, and the slider 6 is connected to one of the placement platforms 5. This placement platform 5 is connected to the adjustment belt 24 via a connector 25. A slider 28 is slidably connected to track 29. Slider 28 is connected to auxiliary platform 28, which is connected to control belt 24 via connector 22. A guide sleeve 23 is fixed on auxiliary platform 28, and a guide rod 26 is vertically arranged on guide sleeve 23. Guide rod 26 is connected to another placement platform 5, which is also connected to the upper end of connecting rod 31. A guide plate 30 is vertically fixed on worktable 4. The guide plate 30 has a U-shaped clearance guide groove 30a, and a roller 29 is arranged in the U-shaped clearance guide groove 30a. The roller 29 is also connected to the lower end of connecting rod 31. The structure, driven by the regulating belt 24, moves the placement platform 5. With the cooperation of the U-shaped guide groove 30a, rollers 29, guide rods 26, and guide sleeves 23, the two placement platforms 5 move alternately, alternately conveying packaging bags containing chip tubes to the vacuum packaging machine body 2. After the gas in the bag is removed by the vacuum extraction pipe 22, the bag opening is sealed by the upper sealing strip 10 and the lower sealing strip 18. Both placement platforms 5 are slidably connected to a widened platform 16 via auxiliary rods 17. The widened platform 16 has two handles 15 connected to it. A limiting part is formed between the handles 15. Since the chip tubes are of different lengths, the widened platform 16 can be pulled outward as needed, so that it can be used for packaging various products. The position of the widened platform 16 can be easily changed using the handles 15. At the same time, the chip tubes are restricted. After the packaging bag containing the chip tubes is placed on the placement table 5, since the packaging bag has a certain thickness, its mouth can be in a naturally open state, so that when it is close to the vacuum packaging machine body 2, the horizontally retractable vacuum suction tube 22 can be inserted into the mouth of the bag.

[0026] A lower sealing strip 18 is horizontally mounted on the frame 1. The lower sealing strip 18 has an electric heating strip 19, which does not directly contact the packaging bag but serves to heat the lower sealing strip 18. The vacuum packaging machine body 2 has a swing arm 3, on which a mounting base 11 is mounted. A guide block 12 is fixed to the mounting base 11, and a guide post 14 is slidably connected to the guide block 12. A spring 13 is also provided between the guide block 12 and the guide post 14. A horizontally connected element that cooperates with the lower sealing strip 18 is attached to the guide post 14. The upper sealing strip 10 and the frame 1 are also equipped with a horizontally extendable vacuum extraction pipe 22, which can extend between the upper sealing strip 10 and the lower sealing strip 18. With this structure, after the packaging bag is moved to the vacuum packaging machine body 2 on the placement table 5, the bag opening is located between the upper sealing strip 10 and the lower sealing strip 18. The vacuum extraction pipe 22 is inserted into the bag opening, and the upper sealing strip 10 is moved by the swing arm 3. After the upper sealing strip 10 and the lower sealing strip 18 clamp the bag opening, the air is extracted first, and then heat-sealed.

[0027] An electric push rod 20 is installed on the frame 1, and the push rod of the electric push rod 20 is set horizontally. The end of the push rod of the electric push rod 20 is connected to the vacuum pumping pipe 22 through the connecting frame 34. With this structure, the horizontal extension or retraction of the vacuum pumping pipe 22 can be controlled by the electric push rod 20.

[0028] The upper sealing strip 10 is also provided with a semi-circular groove 10a for the vacuum extraction pipe 22 to pass through. A horizontally movable adjustment shaft 35 is mounted on the lower sealing strip 18. The adjustment shaft 35 is also fixedly connected to the connecting frame 34. Several cams 21 that cooperate with the semi-circular groove 10a are fitted on the adjustment shaft 35. Each cam 21 also has a guide post 36. The adjustment shaft 35 has a Z-shaped drive groove 35a that cooperates with the guide post 36. The size of the cams 21 increases sequentially from one end of the adjustment shaft 35 to the other. With this structure, in the initial stage of extraction, after the upper sealing strip 10 and the lower sealing strip 18 meet, the vacuum extraction pipe 22 is located at the semi-circular groove 10a. In the later stages of vacuuming, the vacuum extraction tube 22 needs to be pulled out. Therefore, the vacuum extraction tube 22 can be gradually pulled out by the electric push rod 20. During the process of gradually pulling out the vacuum extraction tube 22, the electric push rod 20 also drives the control shaft 35 to move. With the cooperation of the Z-shaped drive groove 35a and the guide post 36, the corresponding cam 21 rotates. The cam 21 gradually closes the semi-circular groove 10a. Finally, after the vacuum extraction tube 22 is completely pulled out, the cam 21 completely closes the semi-circular groove 10a. Finally, under the action of the cam 21, the upper sealing strip 10 and the lower sealing strip 18, the bag opening is sealed, thereby ensuring the vacuuming effect and the sealing effect.

[0029] Both placement platforms 5 also have anti-slip mats 27.

[0030] Several synchronous pulleys 33 are also installed on the workbench 4. One of the synchronous pulleys 33 is connected to a power motor that can make it rotate. The control belt 24 is sleeved on the synchronous pulley 33. The power motor can drive the synchronous pulley 33 to rotate, and the synchronous pulley 33 can make the control belt 24 rotate as needed.

[0031] In this invention, two reciprocating placement platforms 5 are used. With the help of the widened platform plate 16, it can be used for packaging chip tubes of different lengths. Moreover, while one is packaging, the other can be used for picking and placing, thereby improving packaging efficiency.

[0032] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0033] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
