Technical Field
[0001] The utility model belongs to the technical field of food packaging, and particularly relates to an automatic modified atmosphere packaging machine. Background Art
[0002] As some fresh-keeping products such as food fruits and vegetables, meats, etc. increasingly become the mainstream of food consumption and occupy an increasingly large share in the domestic and foreign markets, applying modified atmosphere packaging to food preservation can greatly extend the shelf life of food, so it has great market potential. In short, the modified atmosphere fresh-keeping packaging machine evacuates the air in the original packaging box and fills it with a mixed gas (nitrogen, oxygen, carbon dioxide) in a certain ratio to effectively preserve and protect the packaged food. Its characteristic is that it does not require high-temperature sterilization, so compound modified atmosphere fresh-keeping can ensure the taste, flavor and nutritional components of the original food. The inside of the automatic modified atmosphere packaging machine is assembled with an upper mold and a lower mold. The upper mold is responsible for pressing the film for thermoplastic molding, and the lower mold is for box loading and gas injection. There is a gap between the upper and lower molds to facilitate the disassembly and assembly of the molds.
[0003] Before the existing automatic modified atmosphere packaging machine packages food, it is necessary to first prepare the plastic wrap and pass it through the inside of the packaging machine from one side to the other side so that the mold inside the packaging machine can press the plastic wrap on the box for thermoplastic molding. However, during the film threading process, it is necessary to first remove the mold inside the packaging machine and then manually pass the plastic wrap through the inside of the machine, which is time-consuming and laborious. Moreover, due to the instability of manual operation, the film threading process may cause jitter, resulting in deformation and damage of the plastic wrap. Content of the Utility Model
[0004] The purpose of the utility model is to provide an automatic modified atmosphere packaging machine, which drives a clamping plate through a sliding handle to pass the plastic wrap through the gap between the upper and lower molds and the tensioning shaft inside the modified atmosphere packaging machine, without the need to disassemble the mold again. The film threading process is smooth and time-saving, avoiding the jitter and damage of the plastic wrap caused by the jitter of manual film threading and improving the film threading quality.

Specific embodiments
[0022] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the specific protection scope claimed by the present utility model.
[0023] Such as Figures 1-4 、 Figure 6As shown in the figure, an automatic modified atmosphere packaging machine includes a modified atmosphere packaging machine 1, a sliding frame 2, and a second clamping plate 203. A first sliding groove 201 is provided inside the sliding frame 2. On one side of the second clamping plate 203, spring columns 211 are symmetrically and fixedly connected. The second clamping plate 203 is elastically connected to a first clamping plate 202 through the spring columns 211. The two second clamping plates 203 are fixedly connected through a second connecting rod 209, and the two first clamping plates 202 are fixedly connected through a first connecting rod 208. One side of the second clamping plate 203 is slidably connected to the first sliding groove 201 through a second sliding rod 207. A rotating ring 204 is rotatably connected to the outer wall of the second sliding rod 207. On the outer wall of the rotating ring 204 and on both sides of the sliding frame 2, sliding handles 215 are symmetrically and fixedly connected. A common end of the two sliding handles 215 is fixedly connected to a third connecting rod 216. A side plate 205 is fixedly connected between the second clamping plate 203 and the second sliding rod 207. The first clamping plate 202 is slidably connected to the side plate 205. A second sliding groove 212 is provided between the second clamping plate 203 and the spring column 211. The bottom of the second sliding groove 212 is a slope. A first sliding rod 206 is slidably connected to the top of the first clamping plate 202. The first sliding rod 206 is slidably connected to the second sliding groove 212 through an inserting handle 213 at one end. An inserting groove 214 for the inserting handle 213 to slide and be inserted is provided at one end of the second sliding groove 212.
[0024] According to the above structure, when the two first sliding rods 206 are slid, since the slope at the bottom of the second sliding groove 212 causes the first sliding rod 206 to rise, the first clamping plate 202 rises accordingly. The third connecting rod 216 slides to one end of the second sliding groove 212, and the spring column 211 expands and contracts accordingly. The inserting handle 213 slides and is inserted into the inserting groove 214, fixing the opening between the first clamping plate 202 and the second clamping plate 203. The plastic wrap is placed into the opening. Then, the first sliding rod 206 is slid to make the inserting handle 213 leave the inserting groove 214. Under the pulling-back of the spring column 211, the first sliding rod 206 slides towards one end of the second sliding groove 212, and the opening closes to clamp the plastic wrap. Hold the third connecting rod 216 and drive the rotating ring 204, the second sliding rod 207, the second clamping plate 203, etc. to slide along the first sliding groove 201 through the sliding handle 215.
[0025] Refer to the appendix Figures 1-2 、 Figure 5, the sliding frame 2 is set as a symmetrical group, with a group consisting of two. The middle section of the sliding frame 2 is arranged inside the modified atmosphere packaging machine 1, and both ends of the sliding frame 2 are fixedly connected to the outer wall of the modified atmosphere packaging machine 1. The second clamping plate 203 is symmetrically and slidably assembled between the two sliding frames 2. Tensioning shafts 104 are symmetrically and fixedly connected to both sides of the modified atmosphere packaging machine 1. A swelling shaft 103 is rotatably assembled between the two tensioning shafts 104 on both sides of the modified atmosphere packaging machine 1. Through grooves 105 are symmetrically formed through the middle of the modified atmosphere packaging machine 1. Support rods 102 are fixedly connected to both sides of the modified atmosphere packaging machine 1 and on one side of the swelling shaft 103. Both ends of the sliding frame 2 are fixedly connected to the support rods 102. The middle section of the sliding frame 2 is set as a straight line, and both sides of the sliding frame 2 are set as curved lines that penetrate both sides of the two tensioning shafts 104. The middle section of the sliding frame 2 penetrates through the through groove 105. Outer expansion columns 101 are fixedly connected to both ends of the modified atmosphere packaging machine 1 and on one side of the through groove 105. Magnetic attraction columns 210 for adsorbing the second clamping plate 203 are symmetrically and fixedly connected to both ends of the sliding frame 2.
[0026] According to the above structure, the connecting rod three 216 drives the first clamping plate 202, the second clamping plate 203 and the plastic wrap to slide along the first sliding groove 201, first pass through the tensioning shaft 104 above the modified atmosphere packaging machine 1, then wind around the outside of the tensioning shaft 104 below the modified atmosphere packaging machine 1, and continue to slide through the through groove 105, that is, the gap between the upper die and the lower die inside the modified atmosphere packaging machine 1, and drive the plastic wrap to wind around the swelling shaft 103 on the other side of the modified atmosphere packaging machine 1. The outer expansion column 101 strengthens the structure of the modified atmosphere packaging machine 1 and facilitates the sliding of the connecting rod three 216. The magnetic attraction column 210 adsorbs and fixes the second clamping plate 203 when it is stationary. The support rod 102 is used to connect the modified atmosphere packaging machine 1 and the sliding frame 2 to fix the sliding frame 2. In the present utility model, the clamping plate is driven by the sliding handle 215, and the plastic wrap passes through the gap between the upper and lower dies inside the modified atmosphere packaging machine 1 and the tensioning shaft 104, without the need to disassemble the die again. The film threading process is smooth and stable, time-saving and labor-saving, avoiding the shaking and damage of the plastic wrap caused by the shaking during manual film threading, and improving the film threading quality.
[0027] The working principle of the present utility model is as follows: Slide the two sliding rods 206. Since the slope at the bottom of the second sliding groove 212 causes the first sliding rod 206 to rise, the first clamping plate 202 rises accordingly. The third connecting rod 216 slides to one end of the second sliding groove 212, and the spring column 211 expands and contracts accordingly. The embedding handle 213 slides and is embedded in the embedding groove 214, so that the opening of the first clamping plate 202 and the second clamping plate 203 is fixed. Place the plastic wrap into the opening, then slide the first sliding rod 206 to make the embedding handle 213 leave the embedding groove 214. Under the pulling back of the spring column 211, the first sliding rod 206 slides towards one end of the second sliding groove 212, and the opening closes to clamp the plastic wrap. Pinch the third connecting rod 216 and drive the rotating ring 204, the second sliding rod 207, the second clamping plate 203, etc. to slide along the first sliding groove 201. The third connecting rod 216 drives the first clamping plate 202, the second clamping plate 203 and the plastic wrap to slide along the first sliding groove 201 together. First, pass through the tensioning shaft 104 above the modified atmosphere packaging machine 1, then wind around the outside of the tensioning shaft 104 below the modified atmosphere packaging machine 1, and continue to slide through the through groove 105, that is, the gap between the upper die and the lower die inside the modified atmosphere packaging machine 1, and drive the plastic wrap to wind around the inflation shaft 103 on the other side of the modified atmosphere packaging machine 1. The outward expansion column 101 strengthens the structure of the modified atmosphere packaging machine 1 and facilitates the sliding of the third connecting rod 216. The magnetic attraction column 210 adsorbs and fixes the second clamping plate 203 when it is stationary. The support rod 102 is used to connect the modified atmosphere packaging machine 1 and the sliding frame 2 to fix the sliding frame 2.
[0028] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices and operation methods not specifically described and explained in the present utility model, unless otherwise specifically stated and limited, are implemented according to the conventional means in the art.
