Description

Technical Field

[0001] The present invention relates to the technical field of food packaging, and specifically relates to a vacuum packaging machine for facilitating the fixation of food. Background Art

[0002] Frozen meat refers to meat products that are slaughtered, pre-cooled and degassed, quickly frozen, and then stored at a temperature below minus 18 degrees Celsius, with the deep meat temperature reaching below minus 6 degrees Celsius. High-quality frozen meat is generally quickly frozen at minus 28 to minus 40 degrees Celsius, and its texture and flavor are not much different from those of fresh meat or chilled meat. If frozen at a lower temperature, there will be significant differences in texture and flavor. Frozen meat in both ways has a long shelf life and is therefore widely used. When packaging frozen meat, a packaging machine is required.

[0003] In the prior art, a Chinese patent with the authorization announcement number CN218199003U discloses a vacuum packaging machine for processing frozen meat. By setting a rotating mechanism inside the device, it is convenient to drive the packaging machine body to move, so as to facilitate taking out the meat on the outer wall of the package. At the same time, the limiting plate set inside the device is convenient for limiting the meat, and by setting a transportation mechanism, it is convenient to quantitatively transport the meat, avoiding manually stacking the meat on one side of the packaging machine body by workers, thereby increasing the automation degree of the device. At the same time, the rotating mechanism set on one side of the device cooperates with the packaging machine body to facilitate vacuum packaging of the meat, solving the problem that the existing packaging machine has a low automation degree because workers need to sequentially place the packaging bag and the meat inside the packaging bag on one side of the packaging machine.

[0004] In the above-described solution, a rotatable rotating wheel is used to achieve quantitative transportation of frozen meat, and the packaging machine body is rotated to lift the packaging machine body to facilitate the taking and placing of the packaged frozen meat by personnel. However, in this solution, they are driven by different power sources, which results in a lack of necessary coordination between them, thereby affecting the operation accuracy. If the cooperation between the two mechanisms is poor, problems such as inaccurate transportation volume or unstable position of the meat during the packaging process may occur.

[0020] The present invention provides a vacuum packaging machine for facilitating the fixation of food. Compared with the prior art, the following beneficial effects are achieved:

[0021] 1. In the present invention, when the food is conveyed on the conveyor belt, the electric push rod reciprocally drives the translation plate to move. The translation plate will move horizontally through the cooperation between the L-shaped slider and the limiting groove. The first intermittent block and the second intermittent block on the translation plate will move synchronously. By using the cooperation between the first intermittent block and the second intermittent block and the pressing wheels on the first lifting rod and the second lifting rod respectively, as well as the reaction forces on the first lifting rod and the second lifting rod, the front intermittent rod and the rear intermittent rod on the first lifting rod and the second lifting rod will be lifted and lowered in sequence. By using the cooperation between the front intermittent rod and the rear intermittent rod, the intermittent conveyance of the food on the conveyor belt is completed, avoiding instability or interlacing during the packaging process, ensuring accurate positioning of the food during the packaging process, and avoiding interlacing, sliding or inaccurate positioning;

[0022] 2. In the present invention, when the translation plate moves horizontally back and forth, the translation plate will synchronously drive the first tooth block group on the pushing plate to move horizontally. By using the cooperation between the first tooth block group and the driving gear, when the driving gear rotates, it will drive the driving disc to rotate through the driving shaft. The T-shaped shaft on the driving disc will drive the driving plate to rotate around the driving shaft. By using the cooperation between the driving plate and the L-shaped pulling rod, and the cooperation between the L-shaped pulling rod and the square groove on the side plate, the packaging machine body on the placing plate will be lifted and lowered. By using the sequential lowering of the front intermittent rod and the rear intermittent rod and the synchronous lifting and lowering of the packaging machine body, accurate packaging and picking and placing operations are realized;

[0023] 3. In the present invention, during the process of the L-shaped pulling rod descending, the L-shaped pulling rod will synchronously drive the toothed plate to descend. By using the cooperation between the toothed plate and the auxiliary gear on the adjusting screw rod, the adjusting screw rod will rotate on the side plate through the bearing. By using the cooperation between the adjusting screw rod and the translation block, the translation block will be limited by the translation groove, thereby driving the stabilizing plate to move inward. The two stabilizing plates on the anti-falling vertical plate are used to fix the food, ensuring that the packaging machine body after descending completes the packaging of the food, preventing it from shifting or being unevenly stressed during the vacuum process, so as to ensure that the packaging machine can efficiently and accurately complete the packaging of the food during the vacuum operation;

[0024] 4. In the present invention, when the driving shaft rotates, it will drive the semi-gear to rotate synchronously. When the driving shaft rotates a certain angle and the packaging machine body rises, by using the cooperation between the semi-gear and the second tooth block group on the L-shaped push rod, the L-shaped push rod will move horizontally through the cooperation between the U-shaped sliding rod and the sliding groove. Then, by using the limitation of the positioning slider and the positioning sliding groove, the L-shaped push rod drives the pushing plate to move in the conveying groove during the horizontal movement. By using the conveying of the conveying plate, the packaged food can be moved to the vicinity of the storage box, so that the personnel can directly put the food into the storage box.

[0040] The lifting component includes a pushing plate 32 fixedly installed on the translation plate 26. A first tooth block group 33 is fixedly installed on the lower end surface of the pushing plate 32. Side plates 34 arranged symmetrically are fixedly installed on the placing plate 7. A driving shaft 35 is rotatably installed between the two side plates 34. A driving gear 36 is fixedly installed at the exact middle position of the driving shaft 35. A driving disc 37 is fixedly installed at the end of the driving shaft 35. A T-shaped shaft 38 is fixedly installed on the driving disc 37. A driving plate 39 is rotatably installed on the T-shaped shaft 38. One end of the driving plate 39 away from the T-shaped shaft 38 is rotatably installed with an L-shaped pulling rod 40.

[0041] In this embodiment, when the translation plate 26 moves horizontally back and forth, the translation plate 26 will synchronously drive the first tooth block group 33 on the pushing plate 32 to move horizontally. By using the cooperation between the first tooth block group 33 and the driving gear 36, when the driving gear 36 rotates, it will drive the driving disc 37 to rotate through the driving shaft 35.

And a threaded hole is opened on the translation block 56, and this threaded hole is used in cooperation with the adjusting screw rod 52.

[0045] In this embodiment, during the process of the L-shaped pulling rod 40 descending, the L-shaped pulling rod 40 will drive the tooth plate 54 to descend synchronously. Through the cooperation between the tooth plate 54 and the auxiliary gear 53 on the adjusting screw rod 52, the adjusting screw rod 52 will rotate on the side plate 34 through the bearing 51. By using the cooperation between the adjusting screw rod 52 and the translation block 56, the translation block 56 will drive the stabilizing plate 57 to move inward through the limit of the translation groove 55. The two stabilizing plates 57 on the anti-falling vertical plate 8 are used to fix the food, ensuring that the packaging machine body 50 after descending completes the packaging of the food, preventing it from shifting or being unevenly stressed during the vacuum process, so as to ensure that the packaging machine can efficiently and accurately complete the packaging of the food during the vacuum operation.

[0046] Working principle:

[0047] During use, when the food is conveyed on the conveyor belt 5, the electric push rod 24 drives the translation plate 26 to move reciprocally. The translation plate 26 will move horizontally through the cooperation between the L-shaped slider 31 and the limiting groove 30. The first intermittent block 27 and the second intermittent block 28 on the translation plate 26 will move synchronously. By using the cooperation between the first intermittent block 27 and the second intermittent block 28 and the pressing wheels 17 on the first lifting rod 14 and the second lifting rod 15 respectively, as well as the reaction forces on the first lifting rod 14 and the second lifting rod 15, the front intermittent rods 21 and the rear intermittent rods 22 on the first lifting rod 14 and the second lifting rod 15 will be lifted and lowered in sequence. By using the cooperation between the front intermittent rod 21 and the rear intermittent rod 22, the intermittent conveyance of the food on the conveyor belt 5 is completed;

[0048] When the translation plate 26 moves horizontally in a reciprocating manner, the translation plate 26 will synchronously drive the first tooth block group 33 on the push plate 32 to move horizontally. By using the cooperation between the first tooth block group 33 and the driving gear 36, when the driving gear 36 rotates, it will drive the driving disk 37 to rotate through the driving shaft 35. The T-shaped shaft 38 on the driving disk 37 will drive the driving plate 39 to rotate around the driving shaft 35. By using the cooperation between the driving plate 39 and the L-shaped pulling rod 40, and the cooperation between the L-shaped pulling rod 40 and the square groove 41 on the side plate 34, the packaging machine body 50 on the placing plate 7 will be lifted and lowered. By using the sequential lowering of the front intermittent rod 21 and the rear intermittent rod 22 and the synchronous lifting and lowering of the packaging machine body 50, precise packaging and picking and placing operations are realized;

[0049] During the process of the L-shaped pulling rod 40 descending, the L-shaped pulling rod 40 will synchronously drive the tooth plate 54 to descend. By using the cooperation between the tooth plate 54 and the auxiliary gear 53 on the adjusting screw rod 52, the adjusting screw rod 52 will rotate on the side plate 34 through the bearing 51. By using the cooperation between the adjusting screw rod 52 and the translation block 56, the translation block 56 will be limited by the translation groove 55, thereby driving the stabilizing plate 57 to move inward. By using the two stabilizing plates 57 on the anti-falling vertical plate 8, the food is fixed, ensuring that the packaging machine body 50 after descending completes the packaging of the food, preventing it from shifting or being unevenly stressed during the vacuum process, thereby ensuring that the packaging machine can efficiently and precisely complete the packaging of the food during the vacuum operation;

[0050] When the drive shaft 35 rotates, it will drive the half gear 47 to rotate synchronously. When the drive shaft 35 rotates a certain angle and the packaging machine body 50 rises, by using the cooperation between the half gear 47 and the second tooth block group 46 on the L-shaped push rod 45, the L-shaped push rod 45 will achieve horizontal movement through the cooperation between the U-shaped slide rod 44 and the sliding groove 43. Then, by using the limit of the positioning slider 48 and the positioning chute 49, the L-shaped push rod 45 drives the push plate 32 to move in the conveying groove 9 during the horizontal movement. With the conveying of the conveying plate 11, the packaged food can be moved near the storage box 3, so that personnel can directly put the food into the storage box 3.
