Description

Technical Field

[0001] This utility model relates to the field of shrink packaging machine technology, specifically a fully automatic sealing and shrink packaging machine. Background Technology

[0002] Shrink packaging machines wrap products with heat-shrink film, then heat the wrapped products to shrink the film, thus tightly wrapping the products. Fully automatic shrink packaging machines can automatically feed, wrap, seal, and shrink, saving labor costs.

[0003] In the comparative case, patent publication number CN112407490B relates to the field of automatic sealing and heat shrink packaging machine technology, and discloses a fully automatic sealing and heat shrink packaging machine, including a conveying device. A rolling column is movably installed on the inner side of the top of the conveying device, and a support frame is fixedly installed on the inner side of the middle of the top of the conveying device. A heating plate is fixedly installed at the bottom of the support frame, and an electrical wire is provided at the bottom of the heating plate and electrically connected to a power source. This fully automatic sealing and heat shrink packaging machine uses pressure rollers to press the packaging bag onto the support frame, causing the packaging bag to be heat-melted and bonded at this point. During the rolling of the pressure rollers, the following cutter disc cuts open the bonded portion, slicing the packaging bag from left to right. Because the blade extends into the cutting groove, it ensures that the blade can fully contact the packaging bag, ensuring the quality of the cut, eliminating subsequent bonded portions, and eliminating the possibility of leaks and defects, greatly improving processing efficiency and product quality.

[0004] However, in implementing the relevant technology, the following problems were found in the above-mentioned fully automatic sealing and heat shrink packaging machine. In the comparative case, when the power is turned on, the upper surface of the heating plate generates heat and heats the support frame as well. The cylinder controls the moving frame to move downward, and finally the pressure roller presses the packaging bag onto the support frame, so that the packaging bag is heat-melted and bonded at this point. During the rolling of the pressure roller, the cutter disc following behind will cut open the bonded part, cutting the packaging bag from left to right. Since the blade extends into the cutting groove, it ensures that the blade can fully contact the packaging bag. In the existing shrink packaging machine, the packaging bag is folded and conveyed by multiple sets of rollers during operation, which easily causes creases and wrinkles, affecting the integrity of the subsequent sealing and cutting of the packaging bag and reducing the safety of the shrink packaging machine operation.

[0005] Therefore, it is necessary to redesign and modify the shrink packaging machine to effectively prevent creases and wrinkles from easily appearing when the packaging bag is folded and conveyed through multiple sets of rollers during operation, which would affect the integrity of the subsequent sealing and cutting of the packaging bag.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 5 As shown, the present invention provides a fully automatic sealing and shrink packaging machine, comprising:

[0025] Packaging machine body 1, a winding machine 2 is installed at the bottom of the front end of packaging machine body 1, a roller 3 is movably connected to the inner side of packaging machine body 1 through a bearing, and a leveling mechanism 4 is fixedly connected to the left and right sides of the front end of packaging machine body 1 and at the top of the roller 3.

[0026] The leveling mechanism 4 includes a connecting box 41, a slider 42, a trapezoidal plate 43, and a roller 44. The connecting box 41 is fixedly connected to the left and right sides of the front end of the packaging machine body 1 and to the top of the roller 3. The slider 42 is slidably connected to the front and back ends of the left side of the connecting box 41. The trapezoidal plate 43 is fixedly connected to the left side of the slider 42. The top and bottom of the inner side of the trapezoidal plate 43 are movably connected to the roller 44 through bearings. The limit mechanism 5 is fixedly connected to the right side of the slider 42.

[0027] refer to Figure 3 The limiting mechanism 5 includes a cross block 51, a rectangular plate 52, and a double-headed U-shaped plate 53. The cross block 51 is fixedly connected to the right side of the slider 42. The rectangular plate 52 is fixedly connected to the front end of the inner wall of the connecting box 41. The back end of the rectangular plate 52 is fixedly connected to the back end of the inner wall of the connecting box 41. The right side of the cross block 51 is slidably connected to the left side of the rectangular plate 52. The double-headed U-shaped plate 53 is fixedly connected to the top and bottom of the slider 42. The right side of the back end of the inner wall of the connecting box 41 is movably connected to the driving mechanism 6 through a bearing.

[0028] As a technical optimization of this utility model, the setting of the limiting mechanism 5 enables the double-headed U-shaped plate 53 to move under the influence of external force. The double-headed U-shaped plate 53 moves closer to each other, causing the slider 42 and the cross block 51 to move accordingly. The cross block 51 moves stably along the surface of the rectangular plate 52, thereby achieving the limiting function and preventing the cross block 51 from detaching during the movement.

[0029] refer to Figure 5 The drive mechanism 6 includes a positive and negative threaded rod 61, a turntable 62, a screw sleeve 63, and a docking plate 64. The positive and negative threaded rod 61 is movably connected to the right side of the back end of the inner wall of the connecting box 41 via a bearing. The front end of the positive and negative threaded rod 61 passes through the front end of the connecting box 41 and is fixedly connected to the turntable 62. The front end and back end of the surface of the positive and negative threaded rod 61 and are located inside the connecting box 41 are movably sleeved with the screw sleeve 63. The left and right sides of the screw sleeve 63 are fixedly connected to the docking plate 64. The top and bottom of the docking plate 64 are fixedly connected to one side of the double-headed U-shaped plate 53.

[0030] As a technical optimization of this utility model, the drive mechanism 6 allows the turntable 62 to be manually rotated clockwise. The rotation of the turntable 62 drives the positive and negative threaded rods 61 to rotate. The rotation of the positive and negative threaded rods 61 drives the threaded sleeves 63 to move closer to the inside along the thread direction. The close proximity of the threaded sleeves 63 drives the mating plate 64 to move accordingly, thereby realizing the function of mechanical power transmission and avoiding the phenomenon of asynchronous movement of the threaded sleeves 63.

[0031] refer to Figure 5 A protective sleeve 7 is fixedly fitted at the center of the surface of the positive and negative threaded rod 61. The protective sleeve 7 is used in conjunction with the threaded sleeve 63.

[0032] As a technical optimization of this utility model, the protective sleeve 7 can assist the screw sleeve 63 in its work and at the same time play a protective role, avoiding the phenomenon of the screw sleeves 63 colliding when they get close to each other.

[0033] refer to Figure 4 A groove 8 is provided on the surface of the rectangular plate 52 at the position corresponding to the cross block 51. The groove 8 is used in conjunction with the cross block 51.

[0034] As a technical optimization of this utility model, by setting the slide groove 8, the cross block 51 can move left and right inside the slide groove 8, and at the same time play a limiting role, avoiding the phenomenon of the cross block 51 deviating during the movement.

[0035] refer to Figure 2 There are several rollers 44, which are evenly distributed and are used in conjunction with the trapezoidal plate 43.

[0036] As a technical optimization of this utility model, the setting of the roller 44 can assist the trapezoidal plate 43 in working, avoiding the inability of a single roller 44 to achieve uniform rolling of the packaging bag.

[0037] The working principle and usage process of this utility model are as follows: When in use, the packaging bag is placed on the surface of the winding machine 2, and one end is wrapped with a roller 3 for conveying. Then, the turntable 62 is manually rotated clockwise. The rotation of the turntable 62 drives the positive and negative threaded rods 61 to rotate. The rotation of the positive and negative threaded rods 61 causes the threaded sleeves 63 to move closer to the inside along the threads. The closer the threaded sleeves 63 move together, causing the docking plate 64 to move accordingly. The movement of the docking plate 64 causes the double-headed U-shaped plate 53 to move accordingly. The movement of the double-headed U-shaped plate 53 causes the slider 42 and the cross block 51 to move synchronously. The cross block 51 moves stably along the slide groove 8 on the surface of the rectangular plate 52. Finally, the sliders 42 move closer together, causing the trapezoidal plate 43 to move accordingly. The closer the trapezoidal plates 43 move together, causing the roller 44 to contact the surface of the packaging bag for rolling. When the winding machine 2 is working and conveying the packaging bag, the movement of the packaging bag in the middle of the roller 44 cooperates with the roller 44 to roll its surface to flatten the wrinkles. Finally, the packaging machine 1 completes the automated sealing, cutting, shrinking and other processes.

[0038] In summary, this fully automatic sealing and shrink packaging machine works in conjunction with the packaging body 1, winding machine 2, rollers 3, flattening mechanism 4, connecting box 41, slider 42, trapezoidal plate 43, rollers 44, and limiting mechanism 5. During operation, the slider 42 moves under the influence of external force, and the sliders 42 move closer to each other, causing the trapezoidal plate 43 and rollers 44 to move closer synchronously. The closer proximity of the rollers 44 causes the packaging bag to be rolled in the middle by rotating the rollers 44, thereby flattening the packaging bag and reducing wrinkles and creases. This solves the problem in existing shrink packaging machines where packaging bags are folded and conveyed by multiple sets of rollers during operation, which easily leads to creases and wrinkles, affecting the integrity of the subsequent sealing and cutting of the packaging bag.
