[0025] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0026] The utility model provides a packaging bag pressing mechanism for a vacuum packaging machine, wherein a motor is provided to drive a lead screw to rotate, thereby driving a slider to move, and the slider drives a pressing plate to move. When pressing the packaging bag, the positions of the two pressing plates can be adjusted according to the size of the packaging bag, so that packaging bags of different sizes can be pressed and fixed, thereby enhancing the practicality of the device.

[0027] Figure 1-Figure 3 The following is a schematic diagram of the structure of a vacuum packaging machine packaging bag pressing mechanism according to the present invention. Figure 1-Figure 3 In this embodiment, a packaging bag pressing mechanism of a vacuum packaging machine includes a vacuum packaging machine body 100, a pressing component 200 and an adjusting and moving component 300.

[0028] A placement plate 102 is provided on one side of the upper end of the vacuum packaging machine body 100 , and a U-shaped plate 101 is provided on the upper end of the placement plate 102 .

[0029] The clamping assembly 200 includes a hydraulic push rod 210 vertically arranged in the middle of the U-shaped plate 101, a horizontal plate 220 vertically fixed to the lower end of the hydraulic push rod 210, and a clamping plate 230 arranged on both sides of the middle of the lower end of the horizontal plate 220. A sliding groove is opened at the lower end of the horizontal plate 220. Preferably, in this embodiment, limit rods 221 are vertically fixed on both sides of the middle portion of the upper end of the cross plate 220, and a limit slot is provided on the U-shaped plate 101. The limit rods 221 pass through the limit slots, and the limit rods 221 vertically fixed to the upper end of the cross plate 220 move synchronously with the up and down movement of the cross plate 220. During the up and down movement, a certain friction force is generated between the limit rods 221 and the limit slots of the cross plate 220, thereby ensuring the stability of the cross plate 220 during the up and down movement. The lower end of the pressing plate 230 is provided with multiple elastic members 233, and the lower end of the elastic member 233 is provided with a buffer plate 234. The elastic member 233 and the buffer plate 234 provided at the lower end of the pressing plate 230 play a buffering role for the compressed packaging bag. The lower end of the buffer plate 234 is provided with a protective pad, and the material of the protective pad is rubber. The protective pad provided at the lower end of the buffer plate 234 plays a protective role for the compressed packaging bag.

[0030] The adjustment and movement assembly 300 includes a motor 310 disposed at one end of the horizontal plate 220, a lead screw 320 disposed at the output end of the motor 310, and two symmetrically arranged sliders 330 with threads disposed outside the lead screw 320. The pressure plate 230 is mounted at the lower end of the sliders 330, and the outer wall of the lead screw 320 is provided with two sections of oppositely directed threads. Preferably, in this embodiment, mounting plates 231 are fixed to both sides of the middle portion of the upper end of the pressure plate 230. Bolts 232 are disposed on the outer side of the mounting plate 231 and extend through the mounting plate 231 to the sliders 330. The pressure plate 230 is mounted at the lower end of the sliders 330 by the action of the mounting plate 231 and the bolts 232. Later, the operator can remove the pressure plate 230 by removing the bolts 232, thereby facilitating disassembly and replacement of the pressure plate 230.

[0031] Combine Figure 1-Figure 3The bag pressing mechanism of a vacuum packaging machine of this embodiment is specifically used as follows: the operator places the bag to be pressed on the placing plate 102, and then adjusts the position of the pressing plate 230 according to the size of the bag, starts the motor 310, and the motor 310 drives the lead screw 320 to rotate. The rotating lead screw 320 drives the two sliders 330 to move closer to or away from each other, and then drives the pressing plates 230 to move closer to or away from each other, thereby adjusting the positions of the two pressing plates 230, so that when pressing the bag, it can press and fix bags of different sizes, thereby enhancing its practicality. Then, the hydraulic push rod 210 pushes the pressing plate 230 downward, so that the pressing plate 230 presses the bag. When pressing, the elastic member 233 and the buffer plate 234 provided at the lower end of the pressing plate 230 play a buffering role for the pressed bag, and the protective pad provided at the lower end of the buffer plate 234 plays a protective role for the pressed bag.

[0032] While the present invention has been described above with reference to specific embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
