DETAILED DESCRIPTION

[0029] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0030] Example

[0031] like Figure 1-10As shown, this embodiment discloses a compression packaging machine, including a frame 1, a pressing plate mechanism 2, a sealing mechanism 3 and a driving device 4. The frame 1 is provided with a workbench 11 for placing items to be packaged. The pressing plate mechanism 2 and the sealing mechanism 3 are both arranged on the frame 1 and located above the workbench 11. The pressing plate mechanism 2 is arranged above the sealing mechanism 3. The driving device 4 is arranged at the upper end of the frame 1. The power output end of the driving device 4 is connected to the pressing plate mechanism 2 and is used to drive the pressing plate mechanism 2 to perform lifting and lowering movements in the frame 1. In this embodiment, a sponge mattress packed in a film bag is placed on the workbench 11, and the driving device 4 drives the pressing plate mechanism 2 to perform a descending movement in the frame. Under the pressure of the pressing plate mechanism 2, the sponge mattress is flattened and exhausted. When the air in the film bag is exhausted, the sealing mechanism 3 heat-seals the film bag mouth to complete the compression packaging, so that the volume of the sponge mattress is reduced, which is convenient for transportation.

[0032] In this embodiment, the pressure plate mechanism 2 includes a pressure plate body 21, two groups of first synchronization components 22 and two groups of second synchronization components 23. The upper end surface of the pressure plate body 21 is connected to the power output end of the driving device 4. The first synchronization component 22 is arranged at the opposite ends of the pressure plate body 21, and the second synchronization component 23 is arranged between the first synchronization components 22 and perpendicular to the first synchronization components 22.

[0033] In this embodiment, the first synchronization components 22 include gears 221 provided at two adjacent corners of the pressure plate body 21, a rack 222 vertically provided on the frame 1 and matching the gear 221, and a first synchronization shaft 223 for connecting the gear 221; the second synchronization components 23 include a second synchronization shaft 231 and a bevel tooth 232 for connecting the first synchronization shaft 223 and the second synchronization shaft 231, one end of the bevel tooth 232 is sleeved in the first synchronization shaft 223, and the other end of the bevel tooth 232 is sleeved in the second synchronization shaft 231. Each group of gears 211 slides on the rack 222. Since the first synchronization shaft 223 connects the two gears 221, the pressure plate body 21 can initially maintain the horizontal lifting movement; at the same time, the bevel gear 232 connects the first synchronization shaft 223 and the second synchronization shaft 231. Even if the pressure plate body 21 is subjected to uneven force, it can still maintain the horizontal lifting movement; the first synchronization component 22 and the second synchronization component 23 are used in conjunction with each other, so that the pressure plate body and the flattened sponge mattress are always kept parallel in the horizontal direction, ensuring that the compressed thickness of the sponge mattress remains consistent.

[0034] In this embodiment, the pressing plate mechanism 2 further includes a limiting assembly 24, which includes a limiting bracket 241, a limiting block 242 and a switch seat. The limiting bracket 241 is arranged on the workbench 11 and is located on a side close to the frame 1. The limiting block 242 and the switch seat are both arranged on the limiting bracket 241. The height of the limiting block 242 is adjusted by controlling the switch seat, thereby adjusting the thickness of the compressed sponge mattress.

[0035] In this embodiment, the sealing mechanism 3 includes an upper heat sealing component 31 and a lower heat sealing component 32 . The upper heat sealing component 31 is arranged on one side of the pressure plate mechanism 2 , and the lower heat sealing component 32 is arranged below the upper heat sealing component 31 .

[0036] In this embodiment, the upper heat sealing assembly 31 includes a heat sealing platen 311, a cylinder 312 and a cylinder support 313. The cylinder 312 is arranged on one side of the platen mechanism 2 through the cylinder support 313, and the output end of the cylinder 312 is connected to the heat sealing platen 311. The lower heat sealing assembly 32 includes a heat sealing sheet 321, a heat sealing pad 322 and a heat sealing support 323. The heat sealing pad 322 is arranged on one side of the workbench 11 through the heat sealing support 323, and the heat sealing sheet 321 is arranged on the upper end surface of the heat sealing pad 322. When the platen mechanism 2 completes the compression volume, the cylinder 312 drives the heat sealing plate 311 to move downward and contacts the heat sealing pad 322. The heat sealing sheet 321 heats the film bag mouth to complete the heat sealing process.

[0037] In this embodiment, the sealing mechanism 3 further includes an adjustment component 33, which is disposed on both sides of the workbench 11. The adjustment component 33 includes a hand wheel 331, a spring 332, a pull rod 333, an adjustment pressure plate 334 and a slider 335. The hand wheel 331 is disposed at one end of the pull rod 333, the spring 332 is sleeved on the pull rod 333, and the adjustment pressure plate 334 is slidably disposed at the other end of the pull rod 333 through the slider 335. The compression / extension length of the spring 332 is adjusted by adjusting the hand wheel 331, so as to adjust the position of the adjustment pressure plate 334, so that the adjustment pressure plate 334 can move with the slider 335 to flatten the film bag mouth and avoid edge misalignment or wrinkles.

[0038] In this embodiment, the packaging machine further includes an electric control box 5, and the pressing plate mechanism 2, the sealing mechanism 3 and the driving device 4 are all electrically connected to the electric control box 5. The worker controls the electric control box 5 to uniformly control the operation of the packaging machine, thereby realizing automatic control, which not only saves labor costs but also standardizes product packaging.
