Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging equipment, and in particular to a packaging equipment sealing mechanism. Background Technology
[0002] In food processing, chemical granules, and building material powders, material sealing is a crucial process connecting production, warehousing, and transportation. As industry demands for production efficiency and product quality continue to rise, the continuity of the sealing process and the cleanliness of the materials have become core standards for measuring production levels. Traditionally, material mixing and bagging operations rely on two independent sets of equipment: the mixing equipment thoroughly mixes the materials and temporarily stores them in a silo; subsequently, the mixed materials must be manually transferred to the bagging station using transfer tools or by hand. In some production scenarios, multiple transfers are even required before the materials are fed into the bagging equipment's inlet. This paper proposes developing a packaging equipment sealing mechanism that integrates material mixing and bagging functions. Utility Model Content

The stirred material can fall directly into the packaging bag, solving the problems of material contamination, clumping and loss caused by traditional transfer links. Finally, the packaging bag is sealed by the sealing module.
[0006] In a further embodiment, the receiving module includes: A bracket is fixedly installed on the top of the box, and an avoidance hole is provided on the front side of the bracket; A ball screw, one end of which is rotatably mounted to the top of a bracket, and the other end of which is rotatably mounted with a disc; A first mounting plate is fixedly mounted to the disc, and a second mounting plate is slidably mounted on the front side of the bracket, the second mounting plate being fixedly mounted to the first mounting plate through clearance holes; A first fixing plate is provided, and multiple first fixing plates are symmetrically arranged on both sides of a second mounting plate.

[0025] The encapsulation module 7 includes a fourth fixing plate 71, multiple fourth fixing plates 71 are provided, and multiple fourth fixing plates 71 are symmetrically fixedly installed on the front side of the housing 2; a second cylinder 72, multiple second cylinders 72 are provided, and multiple second cylinders 72 are fixedly installed on the side of the fourth fixing plates 71 that are close to each other; a round rod 73, multiple round rods 73 are provided, and the two ends of multiple round rods 73 are fixedly installed on the side of the fourth fixing plates 71 that are close to each other; a sliding plate 74, multiple sliding plates 74 are provided, and multiple sliding plates 74 are slidably installed on the round rods 73, and the movable ends of the second cylinders 72 are all fixedly installed with the sliding plates 74; a third mounting plate 75, a third mounting plate 76, and a third mounting plate 77. The mounting plate 75 is slidably mounted on the round rod 73. The third mounting plate 75 is located on the side of the slide plate 74 that is close to each other. A spring is provided between the third mounting plate 75 and the left slide plate 74, and the spring is sleeved on the round rod 73. There are multiple heating blocks 76. Multiple heating blocks 76 are fixedly installed on the right side of the third mounting plate 75 and the left side of the right slide plate 74, respectively. The side of the heating blocks 76 that is close to each other has a mounting groove. A heat sealing knife 8 is fixedly installed in the mounting groove of the left heating block 76. Multiple casters 9 are fixedly installed at the bottom of the base 1. A power supply is fixedly installed in the housing 2. The power supply is electrically connected to the heating block 76.
[0026] Specific implementation process: First, the staff moves the entire equipment to a suitable position on the production site using the casters 9 at the bottom of the base 1. Then, they open the detachable cover 49 at the top of the hopper 47 and pour the material to be packaged into the hopper 47 of the receiving module 4. After adding the material, they close the cover 49 to prevent external dust from entering. Then, they adjust the ball screw 42 of the receiving module 4 according to the material characteristics, so that it drives the first mounting plate 44 to move up and down. Then, they adjust the height of the hopper 47 through the second mounting plate 48, while rotating the first mounting plate 44 which is rotatably connected to the second mounting plate 48. The fixed plate 45 finely adjusts the tilt angle of the hopper 47 to ensure that the discharge end of the hopper 47 is precisely aligned with the discharge pipe 55 of the mixing module 5. Then, the mixing module 5 is started, and the first motor 51 and the second motor 53 are turned on simultaneously. The shaft of the first motor 51 drives the conveying rod 52 to rotate to provide power for material conveying. The shaft of the second motor 53 drives the second gear 57 to rotate. The second gear 57 drives the first gear 56 and the sleeve 54 to rotate through the gear belt 58. The mixing rod 59 on the outer wall of the sleeve 54 then evenly mixes the material in the hopper 47 to prevent clumping. Then, the first cylinder 62 of the packaging module 6 is activated. The movable end of the first cylinder 62 pushes the side plate 64 to slide along the guide rods 63 fixed at both ends to the third fixed plate 61. Because the guide rods 63 restrict the movement direction of the side plate 64, the two side plates 64 can stably approach each other. At this time, the open end of the packaging bag to be filled is put into the positioning hole of the mounting block 65 on both sides. Then, the first cylinder 62 is controlled to reset, and the side plate 64 drives the mounting block 65 to separate slightly. The positioning hole is used to open and fix the opening of the packaging bag, so that the packaging bag is kept open and accurately connected to the feeding plate 3 on the front side of the box 2 to wait for the material to fall in. Next, the material that is evenly mixed in the mixing module 5 is discharged from the discharge pipe 55 under the rotation of the conveying rod 52. After being guided by the hopper 47 of the receiving module 4, it falls accurately into the packaging bag fixed in the packaging module 6 through the feeding plate 3 on the front side of the box 2. The staff observes the material filling according to the capacity of the packaging bag. When the material reaches the preset filling amount, the first motor 51 of the mixing module 5 is paused, the material conveying is stopped, and the bagging step is completed. After bagging is completed, the second cylinder 72 of the sealing module 7 is activated. The movable end of the second cylinder 72 pushes the two side slide plates 74 to slide along the round rods 73 fixed at both ends to the fourth fixed plate 71. The right slide plate 74 moves directly to the left, while the left slide plate 74 pushes the third mounting plate 75 to move synchronously to the right through the spring sleeved on the round rod 73. As the slide plates 74 and the third mounting plate 75 move, the two side heating blocks 76 gradually approach each other, and the heating blocks 76 are energized to rapidly heat up. When the two side heating blocks 76 are in contact with the opening of the packaging bag, the springs act as a buffer to prevent excessive pressure from breaking the packaging bag. The heat sealing knife 8 in the mounting groove of the left heating block 76 cooperates with the right heating block 76 to heat-seal and cut the opening of the packaging bag, forming a sealed and neat edge to prevent material leakage. After sealing is completed, the power to the heating block 76 is turned off, the second cylinder 72 is reset, and the two side slide plates 74 and the third mounting plate 75 drive the heating blocks 76 to separate, thus completing the sealing.
