Description

Technical Field

[0001] The invention relates to the technical field of vacuum packaging, in particular to a vacuum packaging device for meat product processing. Background Art

[0002] Meat processing refers to the process of transforming raw meat into meat products with specific flavor, texture and shelf life through a series of processing methods. This process not only includes traditional air-drying, pickling, smoking and other processes, but also covers modern freezing, vacuum packaging, fermentation and other technologies. Depending on the depth of processing, meat processing can be divided into primary processing and deep processing.

[0003] After searching, the Chinese patent with publication number CN220391619U discloses a vacuum packaging device for meat processing, which relates to the technical field of meat food packaging, including: a transport mechanism, which is composed of multiple parts and components; the measuring mechanism is movably installed above the transport mechanism, the measuring mechanism includes a cylinder, a jacket is fixedly connected to the top of the cylinder, a telescopic plate is fixedly connected to one side of the jacket, a connecting plate is fixedly installed on one side of the telescopic plate, and a quantitative box is fixedly connected to the top of the connecting plate; the sealing mechanism is movably installed above the transport mechanism, the sealing mechanism includes a connecting block, the inner side of the connecting block is fixedly crossed in the through hole, and the inner surface of the connecting hole is fixedly connected with a thread. This new vacuum packaging device for meat processing has a highly integrated structure, is easy and quick to use, can be used directly for vacuum packaging of meat products, and an adjustable size structure is added at the connection of the vacuum processing device. However, this solution still has the following shortcomings when it is actually used:

[0004] In the current meat processing industry, especially for products such as luncheon meat and steak that require high-quality appearance and precise packaging, the traditional vacuum packaging loading process often relies on manual operation. During this process, the staff needs to accurately place the cut meat products one by one on the material tray of the vacuum packaging machine to ensure that each piece or piece of meat is neatly and tightly arranged so that the subsequent packaging operation can proceed smoothly. However, this method of relying on manual loading greatly increases the labor cost, because a sufficient number of skilled workers are required to perform this work uninterruptedly to meet the needs of the production line. Secondly, manual loading significantly reduces the overall efficiency of vacuum packaging.

[0005] Therefore, the present application provides a vacuum packaging device for meat processing to meet the purpose of rapid loading of vacuum packaging. Summary of the invention

[0061] Beneficial effects of the present invention:

[0062] 1. This vacuum packaging device for meat processing realizes the automatic loading process of meat products by setting a loading frame and a unloading component and controlling the movement of the lower and upper pallets through a driving mechanism. This mechanism not only improves production efficiency and reduces manual operation, but also avoids errors and waste that may occur during manual unloading.

[0063] 2. This vacuum packaging device for meat processing is equipped with a transmission component and a shaking component. Under the action of the transmission component, when the rack is driven to slide back and forth in the guide groove, the fixed gear, the connecting rod and the support plate are linked to make the meat products on the support plate vibrate. This vibration helps to remove the overlap between the meat products and make their placement more neat. At the same time, with the support of the spring, the vibration effect is more significant, which further improves the uniform placement of the meat products and provides convenience for subsequent packaging and processing.

[0064] 3. This vacuum packaging device for meat processing realizes the automatic alignment function of meat products by setting a swinging material component and a linkage mechanism of a driving rod, a lever, etc. During the sliding of the driving rack, the interaction between the driving rod and the lever enables the alignment plate to slide along the slide groove, so as to press the meat products tightly and arrange them neatly. This automatic alignment mechanism not only improves the packaging efficiency of meat products, but also ensures the neatness and beauty of the packaging effect. At the same time, by setting the sliding distance and reset timing of the alignment plate, excessive squeezing and damage of the meat products are avoided, thereby ensuring the quality and integrity of the product.

[0077] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0078] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0079] like Figures 1 to 9 As shown, a vacuum packaging device for meat product processing includes a base frame 1; a conveyor belt 2, which is arranged on the inner side of the base frame 1; a vacuum pressing cover 3, which is arranged on one side of the top surface of the base frame 1; a loading frame 4, which is fixedly installed on the other side of the top surface of the base frame 1 through a mounting frame; a material blocking plate 5, which is fixedly installed on the conveyor belt 2; a material unloading assembly, which is arranged on the loading frame 4; a material shaking assembly, which is arranged on the base frame 1 and the conveyor belt 2; a transmission assembly, which is arranged on the base frame 1; and a material swinging assembly, which is arranged on the material shaking assembly.

[0080] When vacuum packaging meat products, the meat products put into the packaging bags can first be placed in the loading frame 4 in order. Under the action of the unloading component, the meat products can be stably placed in the loading frame 4. When vacuum packaging is performed, the conveyor belt 2 can be started to move the material blocking baffle 5 to the bottom of the loading frame 4. At this time, the unloading component can be opened to unload the meat products in the loading frame 4 in an orderly manner. In addition, during the unloading process, the transmission component can drive the shaking component to move so as to shake the meat products to ensure that they are placed more neatly. The swinging component can align the meat products for vacuum packaging. After the meat products are loaded, the conveyor belt 2 is opened again to move the meat products to the bottom of the vacuum pressing cover 3. The vacuum pressing cover 3 can be opened to vacuum-pack the meat products. The working principle and connection method of the vacuum pressing cover 3 are existing mature technologies and will not be elaborated here.

[0081] like Figure 2 , Figure 3 As shown, the unloading assembly includes: two rotating shafts 61, which are symmetrically rotated and mounted on the loading frame 4; two brackets 62, which are respectively fixedly mounted on the ends of the two rotating shafts 61 away from the loading frame 4, and the brackets 62 are composed of a vertical portion, a horizontal portion and an inclined portion. The vertical portion of the bracket 62 located at one end of the loading frame 4 and the inclined portion of the bracket 62 located at the other end of the loading frame 4 are in the same direction; two torsion springs 63 are respectively mounted on the two rotating shafts 61, and the two ends of the torsion springs 63 are respectively connected to the rotating shaft 61 and the loading frame 4 fixedly connected; two lower clamping plates 64, respectively fixedly mounted on the bottom ends of the vertical parts of the two brackets 62; two support rods 65, respectively fixedly mounted on the bottom ends of the inclined parts of the two brackets 62; two groups of upper clamping plates 66, respectively arranged on the two support rods 65, and each group of upper clamping plates 66 is distributed in a linear array on the support rods 65; two groups of through-ports 67, symmetrically opened on the feeding frame 4, each group of through-ports 67 is distributed in a linear array on the feeding frame 4, and the through-ports 67 correspond to the upper clamping plates 66; a driving mechanism, arranged on the feeding frame 4;

[0082] When unloading the meat products in the loading frame 4, in the initial state, the two lower clamping plates 64 are located on both sides of the bottom surface of the loading frame 4, which can block the meat products and prevent them from falling. The two brackets 62 can be rotated in opposite directions under the action of the torsion spring 63 through the driving mechanism. When the brackets 62 rotate, the lower clamping plates 64 can move out of the bottom surface of the loading frame 4, and at the same time, the upper clamping plates 66 can move to the through opening 67 to limit the second-to-last layer of meat products. At this time, the meat products at the bottom can fall under the action of gravity. After the two brackets 62 are reset under the action of the driving mechanism, the lower clamping plates 64 can be reset to limit the meat products in the loading frame 4, and the upper clamping plates 66 can move out of the through opening 67 for re-loading.

[0083] like Figure 2 , Figure 3 As shown, the driving mechanism includes: a fixing frame 68, fixedly mounted on the side wall of the loading frame 4; a transmission shaft 69, rotatably mounted on the inner side wall of the fixing frame 68; two cams 610, respectively fixedly sleeved on both ends of the transmission shaft 69, and the convex tops of the two cams 610 face opposite directions; a driving motor 611, fixedly mounted on the top surface of the bottom frame 1 through a connecting frame, and the output end of the driving motor 611 is fixedly connected to one end of the transmission shaft 69;

[0084] When the driving motor 611 is turned on, the transmission shaft 69 can be driven to rotate, and when the transmission shaft 69 rotates, the cam 610 can be driven to rotate. The convex tops of the two cams 610 face opposite directions, so when the cam 610 rotates, the two brackets 62 can rotate in opposite directions under the action of the torsion spring 63, and as the driving motor 611 continues to drive, the transmission shaft 69 can rotate 360° to reset the two cams 610.

[0085] like Figure 4 , Figure 5 , Figure 6 , Fig. 9 As shown, the material shaking assembly includes: a guide groove 71, which is opened on the top surface of the bottom frame 1 away from the driving motor 611; a guide block 72, which is slidably mounted on the inner side wall of the guide groove 71; a driving rack 73, which is fixedly mounted on the top surface of the guide block 72; a guide frame 74, which is fixedly mounted on the top surface of the conveyor belt 2; a support plate 75, which is slidably mounted on the inner side wall of the guide frame 74, and the horizontal position of the top surface of the support plate 75 is at least lower than the horizontal position of the top surface of the material blocking baffle 5, and the length of the support plate 75 is the same as the length of the material blocking baffle 5; a plurality of springs 76, which are distributed in a linear array between the bottom surface of the support plate 75 and the inner bottom wall of the guide frame 74; a connecting rod 77, which is fixedly mounted on the end of the support plate 75; a fixed gear 78, which is fixedly mounted on the end of the connecting rod 77 away from the support plate 75;

[0086] During the feeding process, the fixed gear position 78 at the end of the connecting rod 77 is located at the end of the driving rack 73. Under the action of the transmission assembly, when the transmission shaft 69 rotates, it can drive the driving rack 73 to slide back and forth in the guide groove 71 through the guide block 72. During the reciprocating sliding of the driving rack 73, since the fixed gear 78 is in a fixed state, the fixed gear 78, the connecting rod 77 and the support plate 75 can vibrate under the action of the teeth, and the vibration is more intense under the action of the spring 76, so that the meat product located on the support plate 75 can be shaken so that the end can be placed against the card baffle 5.

[0087] like Figure 2 , Figure 4 , Figure 7 As shown, the transmission assembly includes: a sealing cylinder 81, which is fixedly mounted on the top surface of the bottom frame 1 away from the driving motor 611, and the sealing cylinder 81 is located directly below the transmission shaft 69; a piston plate 82, which is slidably mounted on the inner wall of the sealing cylinder 81; a push rod 83, which is fixedly mounted on the top surface of the piston plate 82, and the top end of the push rod 83 passes through the top surface of the sealing cylinder 81; a connecting pipe 84, which is arranged on the inner side of the bottom frame 1, and the two ends of the connecting pipe 84 are respectively connected to the sealing cylinder 81 and the guide groove 71; a linkage mechanism, which is arranged between the transmission shaft 69 and the push rod 83;

[0088] The transmission shaft 69 rotates 180° to drive the push rod 83 and the piston plate 82 to slide downward along the sealing tube 81 through the linkage mechanism, and then the gas in the sealing tube 81 can be pushed into the guide groove 71 through the connecting pipe 84, and the guide block 72 in the guide groove 71 can be pushed. The transmission shaft 69 continues to rotate 180° to make the piston plate 82 slide upward, and under the action of air pressure, the guide block 72 slides in the opposite direction and resets, thereby driving the driving rack 73.

[0089] like Figure 7 As shown, the linkage mechanism includes: a turntable 85, fixedly mounted on the end of the transmission shaft 69 away from the driving motor 611; a transmission rod 86, rotatably mounted on the side edge of the turntable 85, and the end of the transmission rod 86 away from the turntable 85 is rotatably connected to the top of the push rod 83;

[0090] When the transmission shaft 69 rotates, the turntable 85 can be driven to rotate, and the two ends of the transmission rod 86 are respectively rotatably connected to the side positions of the side of the turntable 85 and the top of the push rod 83, so when the turntable 85 rotates, the push rod 83 can be driven to slide back and forth in the vertical direction.

[0091] like Figure 5 , Figure 8 , Fig. 9As shown, the swing material assembly includes: a lap plate 91, fixedly mounted on the end of the guide frame 74 away from the material blocking baffle 5; two slide grooves 92, symmetrically opened on the top surface of the lap plate 91; an alignment plate 93, slidably mounted on the inner side walls of the two slide grooves 92 through a slider; two springs 94, respectively arranged on the inner sides of the two slide grooves 92, and the two ends of the spring 94 are respectively fixedly connected to the inner side walls of the slide grooves 92 and the side walls of the slider; a lever 95, fixedly mounted on the side wall of the alignment plate 93; a fixed sleeve 96, fixedly mounted on the side wall of the driving rack 73; a driving rod 98, slidably mounted on the inner side wall of the fixed sleeve 96, and the end of the driving rod 98 away from the fixed sleeve 96 is symmetrically provided with inclined surfaces; a spring 3 97, arranged on the inner side of the fixed sleeve 96, and the two ends of the spring 3 97 are respectively fixedly connected to the driving rod 98 and the inner side wall of the fixed sleeve 96, and the elastic force of the spring 3 97 is at least greater than the elastic force of the spring 2 94;

[0092] When the piston plate 82 moves downward and the driving rack 73 slides in the direction away from the sealing cylinder 81, the driving rod 98 at the end of the driving rack 73 can contact the lever 95, and under the action of the inclined surface and the spring three 97, the driving rod 98 can slide along the fixed sleeve 96 and thus slide over the lever 95 to the other side of the lever 95. As the driving rack 73 slides in the opposite direction, the elastic force of the spring three 97 is greater than the elastic force of the spring two 94. Therefore, the driving rod 98 can drive the lever 95 and the aligning plate 93 to slide along the slide groove 92 on the top surface of the lap plate 91. During the sliding process of the aligning plate 93, the meat products can be pressed tightly so that the meat products are neatly arranged. As the aligning plate 93 slides to the end of the slide groove 92, the driving rod 98 can slide over the lever 95 to reset under the action of the spring three 97 and the inclined surface, and the aligning plate 93 can slide in the opposite direction to reset under the action of the spring two 94, so as to avoid affecting the packaging effect of the meat products.
