[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Please see Figures 1-3 The present invention provides the following technical solution: a vacuum compression device for facial towels, including a vacuum packaging machine 1, a working groove 11 at the top of the vacuum packaging machine 1, and an auxiliary positioning mechanism 2, which includes: a lifting plate 21, a translation plate 22, a pressure roller 23, a drive mechanism 24, a tail end face pressing mechanism 25, and a vertical cylinder 26.

[0043] Furthermore, by Figures 1-3As shown, in this embodiment, the lifting plate 21 is located in the working groove 11 and has a vertical degree of freedom of movement. Two translation plates 22 are symmetrically distributed below the lifting plate 21 and have opposite degrees of freedom of movement in the horizontal direction. The pressure roller 23 is rotatably mounted on the bottom end of the translation plate 22. The driving mechanism 24 is drivably connected to the translation plate 22 and is used to drive the two translation plates 22 to move synchronously in opposite directions. Two tail end face pressing mechanisms 25 are symmetrically fixed to the bottom surface of the lifting plate 21 and are used to press the closed end of the packaging bag. The tail end face pressing mechanism 25 includes a vertical plate 251 fixed to the bottom surface of the lifting plate 21 and a pressing strip 252 elastically mounted on the bottom end of the vertical plate 251. The vertical cylinder 26 is fixed inside the vacuum packaging machine 1, and the lifting plate 21 is fixed to the vertical cylinder 26. With the above scheme adopted, when using the piston rod top of 6, the auxiliary positioning mechanism 2 is fixed in the working groove 11 of the vacuum packaging machine 1. First, the vertical cylinder 26 is started to raise the lifting plate 21 to a higher position. Then, the packaging bag containing the face towel is placed flat in the working groove 11, and two symmetrically distributed packaging bags are placed at the same time, with the near end of the two packaging bags being the closed end. Then, the vertical cylinder 26 is started to pull the lifting plate 21 down, and the pressing strip 252 presses the closed end of the packaging bag. Then, the drive mechanism 24 is started to drive the two translation plates 22 to move away from the outside. The translation plates 22 drive the pressure roller 23 to move, which can flatten the face towel and squeeze out the air in the packaging bag. The tail end pressing mechanism 25 ensures the stability of the packaging bag and avoids the problem of the packaging bag shifting and affecting the sealing.

[0044] It should be noted that a standard model of vacuum packaging machine 1 can be used, such as the single-chamber vacuum packaging machine 1 of model DZ-400. The specific working principle of vacuum packaging machine 1 is a well-known existing technology on the market, and will not be elaborated on in this article.

[0045] Optionally, by Figures 1-3 As shown in this embodiment, the tail end pressing mechanism 25 further includes: a fixing block 253, a threaded post 254, a locking nut 255, and a telescopic spring 256. The fixing block 253 is fixed to the bottom of the outer side of the upright plate 251. The threaded post 254 is fixed to the top surface of the pressing strip 252 and passes through the fixing block 253. The locking nut 255 is installed on the protruding end of the threaded post 254 by threaded engagement. The telescopic spring 256 is sleeved on the threaded post 254 and is located between the pressing strip 252 and the fixing block 253. With the above solution, the telescopic spring 256 realizes the elastic installation of the pressing strip 252. When the pressing strip 252 presses the closed end of the packaging bag, the telescopic spring 256 retracts, which not only ensures the stability of the packaging bag, but also avoids mechanical damage caused by rigid clamping.

[0046] It should be noted that the above solution is only a preferred technical solution of this utility model and is not intended to limit this utility model. In actual use, the same effect can be achieved by directly using the telescopic spring 256 to connect the pressing strip 252 and the upright plate 251. After adopting the solution of this utility model, the connection between the pressing strip 252 and the upright plate 251 is more stable, and the initial height of the pressing strip 252 can also be adjusted by turning the locking nut 255.

[0047] Preferably, by Figures 1-3 As shown in this embodiment, the tail end pressing mechanism 25 further includes a rubber strip 257, which is bonded and fixed to the bottom surface of the pressing strip 252. The rubber strip 257 is flexible and can effectively prevent the packaging bag from being scratched by the pressing strip 252.

[0048] Preferably, by Figures 1-3 As shown in this embodiment, the fixing block 253, the threaded post 254, the locking nut 255, and the telescopic spring 256 are all symmetrically distributed in twos, resulting in high stability.

[0049] Optionally, by Figure 1 and Figure 2 As shown, in this embodiment, the driving mechanism 24 includes: a guide slider 241, a driving platform 242, a fixed plate 243, a bidirectional threaded screw 244, and a driving motor 245. A guide sliding hole 211 is machined on the lifting plate 21. The guide slider 241 is fixed to the top of the translation plate 22 and passes through the guide sliding hole 211. The driving platform 242 is fixed to the top of the guide slider 241. Two fixed plates 243 are symmetrically fixed to the top surface of the lifting plate 21. The bidirectional threaded screw 244 is rotatably installed between the two fixed plates 243 and passes through the driving platform 242 and is connected to the driving platform 242 by thread engagement. The driving motor 245 is fixed on the fixed plate 243 and is used to drive the bidirectional threaded screw 244 to rotate. With the above scheme, when in use, the driving motor 245 is started to drive the bidirectional threaded screw 244 to rotate. Under the thread engagement, the driving platform 242 uses the guide slider 241 to drive the translation plate 22 to move.

[0050] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the drive mechanism 24 further includes a guide rod 246. The two guide rods 246 are symmetrically fixed between the two fixed plates 243, and the guide rods 246 pass through the drive platform 242. With the above solution, the two guide rods 246 are used to guide the drive platform 242, which improves the stability of the drive platform 242.

[0051] Preferably, by Figure 1 and Figure 2As shown, in this embodiment, the outer wall of the guide slider 241 abuts against the inner wall of the guide hole 211 to ensure the stability of the guide slider 241.

[0052] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the top surface of the translation plate 22 abuts against the bottom surface of the lifting plate 21, and the bottom surface of the drive platform 242 abuts against the top surface of the lifting plate 21, further improving the stability of the translation plate 22.

[0053] It should be noted that the drive motor 245 and the vertical cylinder 26 are both commercially available conventional devices with built-in power switches. Those skilled in the art can make conventional selections according to their needs. Their working principles are common knowledge known to those skilled in the art and have been fully disclosed in the prior art, so they will not be elaborated on further in this article.

[0054] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0055] Components not described in detail in this article are existing technologies.

[0056] The working principle and usage process of this utility model: When using the vacuum packaging machine 1 of this utility model, the auxiliary positioning mechanism 2 is fixed in the working groove 11 of the vacuum packaging machine 1.

[0057] First, start the vertical cylinder 26 to raise the lifting plate 21 to a higher position. Then, place the packaging bag containing the face towel flat in the working groove 11, and place two symmetrically distributed packaging bags at the same time, with the near ends of the two packaging bags being closed.

[0058] Then, the vertical cylinder 26 is activated to pull the lifting plate 21 down, and the pressing strip 252 presses the closed end of the packaging bag. Then, the drive mechanism 24 is activated to drive the two translation plates 22 to move away from the outside. The translation plates 22 drive the pressure roller 23 to move, which can flatten the face towel and squeeze out the air in the packaging bag. The tail end pressing mechanism 25 ensures the stability of the packaging bag and avoids the packaging bag from shifting and affecting the sealing.

[0059] Finally, turn on the vacuum packaging machine 1, extract the air from the working slot 11 to make the working slot 11 a vacuum state, and seal the packaging bag.
