Description

Technical Field

[0001] This utility model relates to the field of vacuum equipment technology, specifically to a vacuum tube rack. Background Technology

[0002] After packaging the product, air needs to be extracted using specialized equipment to maintain a high vacuum inside the bag. This helps prevent food spoilage, inhibits microbial growth and reproduction, and, importantly, prevents food oxidation. The extraction process requires a suction pipe inserted into the bag to remove air from the outside. A vacuum pump is then used to extract the air, which is subsequently released from the bag. The existing technology has the following problems:

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1 , Figure 2 As shown, this utility model provides a vacuum tube rack, including a vacuuming mechanism 1. An adjustment mechanism 2 is provided on the top of the vacuuming mechanism 1, and a pressing mechanism 3 is provided on the rear side of the vacuuming mechanism 1. The vacuuming mechanism 1 includes a U-shaped plate 11. A vacuum tube 12 is fixedly installed on the inner wall of the U-shaped plate 11. A vacuum tube connection end 13 is fixedly connected to the right rear end of the U-shaped plate 11. The front end of the vacuum tube connection end 13 passes through the inner cavity of the U-shaped plate 11 and communicates with the vacuum tube 12. A flat vacuum pipe 14 that passes through its inner cavity is fixedly connected to the middle of the front side of the vacuum tube 12. Vacuum hoses 15 that pass through its inner cavity are fixedly connected to the left and right sides of the front end of the vacuum tube 12. The two vacuum hoses 15 are located on the left and right sides of the flat vacuum pipe 14, respectively.

[0023] In use, the flat suction pipe 14 is inserted into the packaging bag, and the vacuum tube connection end 13 is connected to the vacuum pump. The suction pipe 12 can be used to evacuate the flat suction pipe 14 and the two suction hoses 15.

[0024] like Figure 3As shown, the adjustment mechanism 2 includes a left and right adjustment box 21, which is fixedly installed on the top of the U-shaped plate 11. An adjustment groove 22 is provided on the front side of the left and right adjustment box 21. A positive and negative threaded rod 23 is movably installed on the left side of the inner wall of the adjustment groove 22. The right end of the positive and negative threaded rod 23 passes through to the right side of the left and right adjustment box 21 and is fixedly installed with a knob 24. The left and right sides of the outer wall of the positive and negative threaded rod 23 are respectively provided with threaded walls with opposite threads. An adjustment plate 25 is threadedly installed on the outer wall of both threaded walls. An L-shaped hanging plate 26 is fixedly installed on the front side of both adjustment plates 25. The vertical part of both L-shaped hanging plates 26 is located on the front side of the U-shaped plate 11. A flat suction side pipe 27 is fixedly connected to the front side of the vertical part of both L-shaped hanging plates 26. The rear ends of the two flat suction side pipes 27 pass through to the rear side of the vertical part of the two L-shaped hanging plates 26 and are respectively connected to the end of the two suction hoses 15 away from the suction pipe 12.

[0025] Depending on the size of the packaging bag to be vacuumed, the knob 24 can be rotated, which will rotate the positive and negative threaded rod 23 in the adjusting slide 22. The threaded wall of the positive and negative threaded rod 23 with opposite threads on the left and right sides of the outer wall is connected to the threads of the two adjusting plates 25, which will drive the L-shaped hanging plate 26 to move in the opposite direction. This will cause the flat vacuum side tube 27 to gradually move away from the flat vacuum pipe 14. At the same time, the soft vacuum hose 15 will not hinder the vacuuming effect through the flat vacuum side tube 27 after adjustment. At this time, the two flat vacuum side tubes 27 inserted into the packaging bag along with the flat vacuum pipe 14 will also follow the flat vacuum pipe 14 to perform vacuuming, so that the vacuuming is more uniform and faster.

[0026] like Figure 4 , Figure 5 As shown, the clamping mechanism 3 includes a clamping control box 31, which is fixedly installed on the rear side of the U-shaped plate 11. A clamping drive groove 32 is provided on the front side of the clamping control box 31. A positive and negative threaded rod 33 is movably installed on the bottom of the inner wall of the clamping drive groove 32. The top of the positive and negative threaded rod 33 extends through to the top of the clamping control box 31 and is fixedly installed with a knob 34. The upper and lower sides of the outer wall of the positive and negative threaded rod 33 are provided with threaded walls 2 with opposite threads. An L-shaped clamping plate 35 is threaded on the outer wall of both threaded walls 2. A squeezing mechanism 36 is provided at the opposite ends of the vertical part of the two L-shaped clamping plates 35. The two squeezing mechanisms 36 are located on the upper and lower sides of the flat air extraction pipe 14 and the two flat air extraction side pipes 27, respectively. Each squeezing mechanism 36 includes a squeezing plate 361. An airbag 362 is fixedly installed on the opposite side of the two squeezing plates 361.

[0027] Before vacuuming, the inlet end of the packaging bag can be fitted onto the two flat suction side tubes 27 and the flat suction pipe 14, and positioned between the opposing faces of the two extrusion mechanisms 36. Then, the knob 34 on the top of the clamping control box 31 can be rotated to drive the positive and negative threaded rods 33 in the clamping drive groove 32 to rotate. The two extrusion plates 361 can be controlled to move closer to each other by using the threaded walls with opposite threads on the upper and lower sides of the outer wall of the positive and negative threaded rods 33 and the threaded connection at the horizontal position of the two L-shaped clamping plates 35. The airbags 362 are used to clamp the packaging bag fitted onto the upper and lower sides of the flat suction pipe 14 and the two flat suction side tubes 27. The soft filling effect of the airbags 362 improves the sealing after clamping, thereby improving the stability of vacuuming and avoiding a large amount of air leakage.

[0028] The working principle of this vacuum tube rack will be explained in detail below.

[0029] like Figure 1-5 As shown, in use, the flat vacuum tube 14 is inserted into the packaging bag, and the vacuum tube connection end 13 is connected to the vacuum pump. The vacuum tube 12 is used to evacuate the flat vacuum tube 14 and the two vacuum hoses 15. Simultaneously, the knob 24 can be rotated according to the desired size of the vacuum packaging bag, thereby rotating the positive and negative threaded rod 23 in the adjusting groove 22. The threaded walls on the opposite sides of the outer wall of the positive and negative threaded rod 23 are connected to the threads of the two adjusting plates 25, causing the L-shaped hanging plate 26 to move in opposite directions. This gradually moves the flat vacuum side tube 27 away from the flat vacuum tube 14. The flexible vacuum hose 15 does not obstruct the vacuuming effect through the flat vacuum side tube 27 after adjustment. At this time, the two flat vacuum side tubes 27, which are inserted into the packaging bag along with the flat vacuum tube 14, will also move simultaneously with the flat vacuum tube 14. The suction pipe 14 is used for suction, which makes the suction faster and more uniform. Before vacuuming, the inlet end of the packaging bag can be placed on the two flat suction side pipes 27 and the flat suction pipe 14, and placed between the two extrusion mechanisms 36. Then, the knob 34 on the top of the clamping control box 31 can be rotated to drive the positive and negative threaded rod 33 in the clamping drive groove 32 to rotate. The two extrusion plates 361 can be controlled to move closer to each other by using the threaded wall with opposite threads on the upper and lower sides of the outer wall of the positive and negative threaded rod 33 and the threaded connection at the horizontal position of the two L-shaped clamping plates 35. The air bag 362 is used to clamp the packaging bag placed on the upper and lower sides of the flat suction pipe 14 and the two flat suction side pipes 27. The soft filling effect of the air bag 362 improves the sealing after clamping, thereby improving the stability of vacuuming and avoiding a large amount of air leakage.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
