Description

Technical Field

[0001] This invention relates to the field of vacuum packaging machine technology, specifically to a vacuum packaging machine for finished mutton slices. Background Technology

[0002] Vacuum packing machines utilize existing technology to create a vacuum inside packaging bags, thereby delaying oxidation and deterioration of the contents, making the bags more moisture-proof and waterproof, preventing evaporation and loss, reducing bag volume, lowering logistics and transportation costs, and ensuring a tighter, more secure packaging bag to prevent items from rolling or being squeezed during transport. This effectively guarantees the integrity of the goods during transit. Therefore, vacuum packing machines are widely used in the food, agricultural products, pharmaceutical, and electronics industries.

[0003] Currently, the working principle of vacuum packaging machines generally falls into two categories. One is to use a vacuum chamber and a vacuum system to create a negative pressure environment for the packaging bag and items placed inside, thereby expelling the air from the packaging bag and achieving the purpose of vacuum packaging. The other is to insert a vacuum tube into the opening of the packaging bag, use a vacuum pump to extract the air from the packaging bag through the vacuum tube, and then use a heat-sealing device to heat-seal the opening of the packaging bag to complete the purpose of vacuum packaging the items.

[0004] In the process of vacuum packaging finished mutton slices, because the packaging bags used to package the finished mutton slices are relatively large, it is difficult to use a vacuum packaging machine with a vacuum chamber for packaging. The common method is to use a vacuum packaging method with an air extraction tube to extract air from the packaging bag. However, the mutton slices processed in the existing technology are generally rolled up, so the middle of the mutton slices is hollow. When the air is extracted from the inside of the packaging bag using the air extraction tube, the packaging bag will shrink, which will cause the mutton slices at the edges to deform. Summary of the Invention

[0005] This invention proposes a vacuum packaging machine for finished mutton slices, which solves the problem in the prior art where the packaging bag easily squeezes and deforms the mutton slices at the edges during the packaging process.

[0006] The technical solution of the present invention is as follows: A vacuum packaging machine for finished mutton slices, comprising a vacuum packaging machine body, wherein the vacuum packaging machine body has a vacuum pumping device and a bottom heat-melting device, and further comprising:

[0007] A fixed bracket is fixedly connected to the body of the vacuum packer, and a transverse sliding groove is provided on the fixed bracket;

[0008] The material feeding tray is slidably connected to the transverse sliding groove frame. The packaging bag is placed on the outside of the material feeding tray. A support tray is provided at the bottom of the material feeding tray to support the bottom of the packaging bag.

[0009] The material feeding tray has multiple abutment bars on both sides, and a flexible mounting structure is provided between the fixed bracket and the multiple abutment bars located on the same side.

[0010] The spacer plate is provided on both sides of the material feeding tray. The spacer plate is located between the material feeding tray and the multiple abutting supports. After the material feeding tray is removed from the packaging bag, the spacer plate also moves towards the direction of the transverse sliding groove frame, so that the abutting supports abut against the side of the packaging bag, reducing the gap on the inner edge of the packaging bag.

[0011] The rotating flap is rotatably mounted on one side of the transverse sliding groove frame. The rotating flap prevents the packaging bag from moving with the feeding tray and cooperates with the bottom hot melt equipment.

[0012] Both sides of the material feeding tray are provided with sliding supports, which are slidably connected to the transverse sliding groove frame. One side of the spacer plate is fixedly connected to the sliding support. A first drive cylinder is provided on the transverse sliding groove frame, and the output end of the first drive cylinder is connected to one side of the material feeding tray.

[0013] The material feeding tray is provided with multiple support rods on one side near the transverse sliding groove frame, and the support rods are located on the side of the material feeding tray.

[0014] The bottom of the vacuum packing machine body is provided with a rotating bracket, the rotating bracket has a rotating shaft, one side of the support tray is connected to the rotating shaft, and the vacuum packing machine body is provided with a second drive cylinder to drive the support tray to flip.

[0015] The elastic installation structure includes a mounting vertical plate and a receiving cylinder seat. The mounting vertical plate is fixedly connected to the fixed bracket. Multiple offset components are provided on the mounting vertical plate. Each offset component corresponds to one of the abutment bars. A receiving cylinder seat is provided on each offset component. A push rod is slidably connected inside the receiving cylinder seat. The push rod is connected to the abutment bar. A spring is provided between the receiving cylinder seat and the push rod.

[0016] The offset component includes a rotating frame and a through support groove. The rotating frame is fixedly connected to the mounting vertical plate. Mounting shafts are rotatably connected to both the upper and lower sides of the rotating frame. The receiving cylinder is disposed between the two mounting shafts. The through support groove is provided on the side of the receiving cylinder facing the rotating frame.

[0017] Both sides of the fixed bracket are rotatably equipped with take-up drum seats, on which traction ropes are wound. The traction ropes abut against the multiple through support slots, and one side of the traction ropes is connected to one side of the spacer plate. The fixed bracket is equipped with a first drive motor that drives the take-up drum seats to rotate. The traction ropes follow the spacer plate and move, causing the abutment support bars to shift towards the direction of the transverse sliding slot frame.

[0018] The top of the transverse sliding slot frame is provided with a rotating slot frame, and a drive shaft is rotatably connected to the rotating slot frame. One side of the rotating flap is connected to the drive shaft, and a second drive motor for driving the drive shaft to rotate is provided on the rotating slot frame.

[0019] An air extraction tube is installed through the bottom of the material feeding tray. The air extraction tube extends through one side of the material feeding tray to form an air extraction extension section. The other side of the air extraction tube is connected to the vacuum extraction device. The air extraction extension section is moved into the opening of the packaging bag to work with the vacuum extraction device to extract air from the packaging bag.

[0020] The top of the bottom heat-melting device is equipped with a heat-melting platform. The rotating flip plate squeezes the opening of the packaging bag and fits it against the heat-melting platform to heat-seal the packaging bag.

[0021] The working principle and beneficial effects of this invention are as follows:

[0022] When vacuum-packing rolled mutton slices, this invention first extends a feeding tray from the transverse sliding groove frame. Then, a packaging bag is placed over the outside of the feeding tray. Next, mutton slices are stacked onto the feeding tray inside the packaging bag in a honeycomb pattern. A support tray then supports the bottom of the packaging bag. After stacking the mutton slices, a rotating flap abuts the mutton slices at the bag opening. This causes the feeding tray and the spacer plates on both sides to move inwards towards the transverse sliding groove frame. As the spacer plates move laterally, the abutment bars on both sides sequentially abut against the sides of the packaging bag, reducing gaps on the sides. The rotating flap prevents the mutton slices from following the feeding tray. The material tray is removed from the packaging bag. After the material tray is completely removed from the packaging bag, a rotating flap and a hot-melt platform are used to seal the opening of the packaging bag, leaving only the suction tube extension section inside the packaging bag. The vacuum equipment, in conjunction with the suction tube, sucks out the air from inside the packaging bag, creating a vacuum state inside the packaging bag. During the vacuuming process, because the side of the packaging bag is in direct contact with the mutton slices, the packaging bag will not undergo significant deformation, effectively preventing the mutton slices inside from being squeezed and deformed. Then, the suction tube extension section is quickly removed from the packaging bag, and the rotating flap and the hot-melt platform are used to heat-seal the opening of the packaging bag, completing the vacuum packaging process for the mutton slices.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0037] This embodiment presents a vacuum packaging machine for finished mutton slices. Please refer to [link / reference]. Figure 1 and Figure 7 The vacuum packaging machine body 1 includes a vacuum pumping device 2 and a bottom heat-sealing device 3. The vacuum pumping device 2 and the bottom heat-sealing device 3 are the main equipment used on the vacuum packaging machine body 1 in the prior art. They are used to implement the vacuuming process inside the packaging bag and the heat-sealing process at the opening of the packaging bag, respectively, to realize the vacuum packaging operation of mutton slices.

[0038] Also includes mounting bracket 4, please refer to Figure 1The fixed bracket 4 is fixedly connected to the vacuum packaging machine body 1. The fixed bracket 4 is provided with a horizontal sliding groove 5. The horizontal sliding groove 5 is slidably connected to the feeding tray 6. The packaging bag is placed on the outside of the feeding tray 6. The feeding tray 6 can make the rolled mutton slices distributed in a honeycomb pattern inside the packaging bag.

[0039] Sliding supports 11 are provided on both sides of the material feeding tray 6. Please refer to [link / reference]. Figure 1 The sliding support 11 is slidably connected to the transverse sliding groove frame 5. One side of the spacer plate 9 is fixedly connected to the sliding support 11. The transverse sliding groove frame 5 is provided with a first drive cylinder 12. The output end of the first drive cylinder 12 is connected to one side of the material discharge tray 6. When it is necessary to remove the material discharge tray 6 from the packaging bag, the first drive cylinder 12 is activated, which drives the material discharge tray 6 and the sliding support 11 to move together to the inside of the transverse sliding groove frame 5.

[0040] The material tray 6 is provided with multiple support rods 13 on one side near the transverse sliding groove frame 5. Please refer to [link / reference]. Figure 2 The support rod 13 is located on the side of the feeding tray 6. Using multiple support rods 13, the packaging bag can be completely opened between the bottom wall of the feeding tray 6 and the multiple support rods 13, which makes it convenient for the user to put the mutton slices into the packaging bag, and also ensures that when the feeding tray 6 is subsequently removed from the packaging bag, the top of the side wall of the feeding tray 6 will not come into excessive contact with the packaging bag, making the removal of the feeding tray 6 more convenient.

[0041] The bottom of the material tray 6 is provided with a support tray 7, please refer to [link / reference]. Figure 6 The vacuum packing machine body 1 has a rotating bracket 14 at its bottom, with a rotating shaft 15 on the rotating bracket 14. One side of the support tray 7 is connected to the rotating shaft 15. The vacuum packing machine body 1 is equipped with a second drive cylinder 16 that drives the support tray 7 to rotate. The second drive cylinder 16 is rotatably mounted on the vacuum packing machine body 1 via a hinge seat, and the output end of the second drive cylinder 16 is also rotatably connected to the bottom of the support tray 7. When the second drive cylinder 16 is started, it pushes the support tray 7 to rotate along the center point of the rotating shaft 15. After the packaging bag is placed on the outside of the feeding tray 6, the support tray 7 is used to support the bottom of the packaging bag.

[0042] Multiple abutment supports 8 are provided on both sides of the material discharge tray 6. Please refer to [link / reference]. Figure 2 , Figure 4 and Figure 5A flexible mounting structure is provided between the fixed bracket 4 and multiple abutment supports 8 located on the same side. Spacer plates 9 are provided on both sides of the material dispensing tray 6, located between the material dispensing tray 6 and the multiple abutment supports 8. After the material dispensing tray 6 is removed from the packaging bag, the spacer plates 9 also move towards the transverse sliding groove frame 5, causing the abutment supports 8 to abut against the side of the packaging bag, reducing the gap at the inner edge of the packaging bag. The flexible mounting structure includes a mounting vertical plate 101 and a receiving cylinder seat 102. The mounting vertical plate 101 is fixedly connected to the fixed bracket 4, and multiple offset components are provided on the mounting vertical plate 101, each corresponding to one of the abutment supports 8. The offset assembly is provided with a receiving cylinder seat 102, and a push rod 103 is slidably connected inside the receiving cylinder seat 102. The push rod 103 is connected to the abutment support 8. A spring 104 is provided between the receiving cylinder seat 102 and the push rod 103. When the material discharge tray 6 and the spacer plate 9 move inward to the side of the transverse sliding groove frame 5, the spacer plate 9 will gradually separate from the multiple abutment supports 8. Under the action of the spring 104, the push rod 103 is pushed from inside the receiving cylinder seat 102 toward the material discharge tray 6, so that the abutment support 8 directly contacts the side of the packaging bag, squeezes the side of the packaging bag to fit with the mutton slices, and reduces the deformation area of ​​the packaging bag during the vacuuming process.

[0043] Furthermore, the length of the spacer plate 9 used in this invention is shorter than that of the material tray 6. Therefore, when the material tray 6 and the spacer plate 9 are moved back between the multiple abutment bars 8 on both sides, the two sides of the material tray 6 will first contact the abutment bars 8, causing the abutment bars 8 to move a certain area towards the receiving cylinder 102. Then, the spacer plate 9 will contact the abutment bars 8 again, causing the abutment bars 8 to continue moving towards the receiving cylinder 102. The spring 104 will also adaptively contract within the receiving cylinder 102, ultimately keeping the abutment bars 8 in contact with the spacer plate 9.

[0044] In this invention, the moving distance of the abutment support 8 driven by the elastic force of the spring 104 is slightly greater than the combined thickness of the side walls of the spacer plate 9 and the material tray 6. This small movement will not cause the abutment support 8 to damage the mutton slices on the side of the packaging bag.

[0045] The offset assembly includes a rotating frame 111 and a through support groove 113, please refer to [link / reference]. Figure 5The rotating frame 111 is fixedly connected to the mounting vertical plate 101. Mounting shafts 112 are rotatably connected to both the upper and lower sides of the rotating frame 111. The receiving cylinder seat 102 is positioned between the two mounting shafts 112. A through support groove 113 is provided on the side of the receiving cylinder seat 102 facing the rotating frame 111. When the spacer plate 9 is actually pulled out from between the multiple abutting supports 8, to improve the smoothness of the spacer plate 9's movement, the spacer plate 9 will move laterally, causing the abutting supports 8 and the receiving cylinder seat 102 to move. 2. The center point of the diffraction mounting shaft 112 is rotated to provide a driving force for the movement of the spacer plate 9. When the spacer plate 9 moves back between the multiple abutting supports 8, the abutting supports 8 are made to face the spacer plate 9, so that the spacer plate 9 and the multiple abutting supports 8 can abut against each other again. Under the action of the rotating frame 111, the receiving cylinder seat 102 and the abutting supports 8 are rotated back to be perpendicular to the material discharge tray 6 and then the rotation stops. The receiving cylinder seat 102 and the abutting supports 8 will only rotate to one side of the transverse sliding groove frame 5.

[0046] Both sides of the fixed bracket 4 are rotatably equipped with take-up drum seats 121. Please refer to [link / reference]. Figure 3 A traction rope 122 is wound on the take-up drum 121. The traction rope 122 abuts against multiple through support slots 113, and one side of the traction rope 122 is connected to one side of the spacer plate 9. When the spacer plate 9 moves laterally, it will drive the traction rope 122 to move synchronously, adjusting the position of the traction rope 122. When the traction rope 122 moves, it will drive the abutment support 8 to flip or reset to one side of the transverse sliding groove frame 5 through the friction with the through support slots 113. A first drive motor 123 is provided on the fixed bracket 4 to drive the take-up drum 121 to rotate. The traction rope 122 moves with the spacer plate 9, driving the abutment support 8 to shift in the direction of the transverse sliding groove frame 5. When the traction rope 122 moves with the spacer plate 9, the first drive motor 123 is started, driving the take-up drum 121 to rotate on the fixed bracket 4, winding or unwinding the traction rope 122 to adapt to the position of the spacer plate 9.

[0047] A rotating flap 10 is rotatably mounted on one side of the transverse sliding groove frame 5. Please refer to [link / reference]. Figure 2The rotating flap 10 prevents the packaging bag from moving with the feeding tray 6 and cooperates with the bottom hot-melt equipment 3. The top of the horizontal sliding groove frame 5 is provided with a rotating groove frame 201. A drive shaft 202 is rotatably connected to the rotating groove frame 201. One side of the rotating flap 10 is connected to the drive shaft 202. The rotating groove frame 201 is provided with a second drive motor 203 for driving the drive shaft 202 to rotate. When it is necessary to remove the feeding tray 6 from the packaging bag containing mutton slices, the second drive motor 203 is started to drive the drive shaft 202 to rotate, so that the rotating flap 10 rotates along the center point of the drive shaft 202. First, the rotating flap 10 abuts against the mutton slices located at the opening of the packaging bag. When the feeding tray 6 is removed from the packaging bag, the rotating flap 10 abuts against the mutton slices to prevent the mutton slices from moving out of the packaging bag with the feeding tray 6.

[0048] An air extraction tube 17 is installed through the inner bottom of the material discharge tray 6. Please refer to [link / reference]. Figure 4 and Figure 7 The suction tube belt 17 passes through one side of the material discharge tray 6 to form a suction extension belt section 18. The other side of the suction tube belt 17 is connected to the vacuum pumping device 2. The suction extension belt section 18 is moved into the opening of the packaging bag and works with the vacuum pumping device 2 to extract the air from the packaging bag. During the process of the material discharge tray 6 being removed from the packaging bag, the material discharge tray 6 is completely removed from the packaging bag, while the suction extension belt section 18 remains inside the packaging bag. Then, the flip plate 10 is rotated to squeeze the upper and lower sides of the opening of the packaging bag to fit together. The suction extension belt section 18 is trapezoidal, which makes it easy to keep the opening of the packaging bag closed. Then, the vacuum pumping device 2 is started to extract the air from the packaging bag through the suction tube belt 17. Then, the first drive cylinder 12 continues to drive the material discharge tray 6 to move, and the suction extension belt section 18 is removed from the packaging bag. Then, the flip plate 10 is rotated to completely seal the packaging bag.

[0049] A hot melt platform 19 is provided on the top of the bottom hot melt device 3. Please refer to [link / reference]. Figure 7 Rotate the flip plate 10 to squeeze the opening of the packaging bag and fit it with the hot melt platform 19 to heat melt and seal the packaging bag. The bottom hot melt device 3 can generate heat on the hot melt platform 19, which will eventually heat melt and seal the opening of the packaging bag, thus completing the vacuum packaging operation of the mutton slices.

[0050] When the finished mutton slice vacuum packaging machine needs to pack mutton slices into packaging bags, it first places the packaging bag on the outside of the feeding tray 6, and then stacks the mutton slices on the feeding tray 6 inside the packaging bag, so that the mutton slices are stacked in a honeycomb pattern inside the packaging bag. At the same time, the second drive cylinder 16 is driven to drive the support tray 7 to support the bottom of the packaging bag. After the mutton slices are stacked, the rotating flip plate 10 is used to abut the mutton slices located at the opening of the packaging bag. Then, the feeding tray 6 and the spacer plates 9 on both sides are driven to move laterally to the inside of the sliding groove frame 5. As the spacer plates 9 move laterally, the abutting support strips 8 located on both sides abut against the side of the packaging bag in turn, reducing the gaps on the side of the packaging bag. The rotating flip plate 10 is used to prevent the mutton slices from moving out of the packaging bag along with the feeding tray 6.

[0051] After the material tray 6 is completely removed from the packaging bag, the rotating flap 10 and the hot-melt platform 19 are used to seal the opening of the packaging bag, leaving only the suction tube 17 with its suction extension section 18 extending into the packaging bag. The vacuum pump 2 is used in conjunction with the suction tube 17 to suck up the air from the packaging bag, creating a vacuum inside the packaging bag. Then, the suction extension section 18 is quickly removed from the packaging bag, and the rotating flap 10 and the hot-melt platform 19 are used to heat-seal the opening of the packaging bag, completing the vacuum packaging process for the mutton slices.

[0052] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
