Description

Technical Field

[0002] In the field of industrial packaging, the automatic bagging and re-bagging machine is a key equipment to achieve efficient packaging of granular products. Its main function is to accurately pack a large number of granular products into packaging bags according to the predetermined weight, and automatically complete the sealing and conveying process. It is widely used in the chemical, food, building materials and other industries, effectively improving packaging efficiency, reducing labor costs, and ensuring packaging quality consistency, which is of great significance to large-scale production and product circulation.

[0003] However, traditional automated bagging and heavy bagging machines have many shortcomings. During the material filling process, product particles tend to accumulate unevenly in the packaging bag, affecting the packaging appearance and product stability. During subsequent transportation and storage, the unstable center of gravity may cause the packaging bag to topple over and the material to scatter, reducing product integrity and safety. The packaging bag fixing method is poor, mostly simple mechanical clamping or unilateral support, which makes it difficult to achieve all-round stability. Displacement and shaking are prone to occur during the packaging process, which not only interferes with the filling accuracy, but may even damage the packaging bag, increase the defective rate and material loss. In addition, the automation integration of the equipment is limited, and the various operating links are not smoothly connected, and manual intervention and adjustment are often required, such as opening and closing the feed pipe, positioning the packaging bag, etc. The operation is cumbersome and inefficient, and it is easy to introduce human errors.

When the motor is started, the rotating wheel starts to rotate, and the rotation of the rotating wheel drives the driving ring to rotate, thereby causing the threaded tube connected to the driving ring to start rotating. The rotation of the threaded tube controls the threaded rod to move up and down along the mounting plate. Since the internal threads of the threaded tubes on both sides of the mounting plate are set in opposite directions, the rotation of the driving ring will cause the threaded rods on both sides of the mounting plate to move in opposite directions. In conjunction with the reciprocating rotation of the motor, the threaded rods on both sides of the mounting plate begin to move up and down intermittently when the motor is working.

[0017] The present invention provides an automatic bagging and re-bagging machine. It has the following beneficial effects:

[0018] 1. In this automatic bagging and re-bagging machine, when the threaded rod moves downward, it will squeeze the adapter at the bottom, and then squeeze the driving frame through the adapter. The driving frame is limited by the protective cover, so when the driving frame is squeezed by the adapter, its bottom will deflect inward, thereby causing the adjustment plate to deflect, that is, the final motion state is that the adjustment plates on both sides are intermittently deflected and then reset, and then through the cooperation between the two adjustment plates, the product particles are filled into the packaging bag in a left-right moving manner after passing through the feeding pipe, thereby greatly improving the uniformity of the distribution of the product particles in the packaging bag, and at the same time, it can also improve the placement stability of the packaging bag after the product particles are filled, and avoid the problem of the packaging bag tipping over and causing the product particles to scatter during the subsequent sealing process.

[0019] 2. In this automatic bagging and re-bagging machine, when the opening of the bag enters the gap between the isolation frame and the protective cover, the electric push rod is started. When the electric push rod is started, it will push the adapter frame on the stabilizing frame to rotate downward, and then drive the support rod to slide along the guide rod through the matching seat, and during the sliding process, the support rod keeps moving downward at the same time, that is, the support rod moves obliquely downward relative to the isolation frame, so that the two sides of the bag are supported by the movement of the support rod, and the bag has been pre-fixed through the gap between the isolation frame and the protective cover, so that the four sides of the bag can be fixed during sub-packaging, thereby improving the overall stability of the bag when filling the product particles. When the adapter frame rotates downward, the corrugated tube between the bottom plate and the top plate will be stretched, so that its interior will be in a negative pressure state, and then air pressure will begin to be extracted from the expansion bag in the slide groove inside the baffle, that is, the expansion bag will begin to shrink, and then the offset plate will be pulled to slide in the slide groove, so that the No. 1 offset hole and the No. 2 offset hole will begin to align, and the feed pipe will be connected with the packaging bag, that is, the feed pipe will be opened synchronously when the packaging bag is supported to start conveying product particles. When the filling is completed, the electric push rod will reset, driving the offset plate to reset, and the feed pipe will be closed again, thereby greatly improving the degree of automation of the equipment and greatly reducing the consumption of manpower and material resources.

[0020] 3. In this automatic bagging and heavy bagging machine, after the corrugated tube is stretched, air pressure will be extracted from the telescopic plate at the same time, so that the telescopic plate begins to shrink, thereby pulling the movable cover to move to the outside of the connecting plate, that is, increasing the extrusion force between the rubber tube and the top of the packaging bag, and finally causing the elastic tube to be squeezed and deformed under the action of pressure, so that the contact area between the rubber tube and the packaging bag changes from linear to planar, thereby further improving the fixing effect of the packaging bag when the packaging bag is filled with product particles, and cooperating with the strut to complete the four-way fixation. When the packaging bag is initially installed in the gap between the isolation frame and the protective cover, the linear extrusion of the rubber tube is used to achieve preliminary fixation, so as to prevent the packaging bag from falling off from the gap between the isolation frame and the protective cover. At the same time, the squeezing effect on the packaging bag is gradually enhanced with the movement of the strut, so as to provide adjustability for the position of the packaging bag when the packaging bag is fixed in all directions, so as to avoid the problem that the fixing effect of the packaging bag by the rubber tube is too strong at the beginning, resulting in the packaging bag being pulled and damaged by the strut due to the inaccurate installation position of the packaging bag when the strut is working.

[0044] During operation, when the product particles need to be sub-packaged, the packaging bag can be automatically transported to the gap between the isolation frame 34 and the protective cover 36 through the device, and then the motor 37 is started to rotate intermittently and put the product particles into the feed hopper 33 at the same time. After the product particles pass through the feed hopper 33 and the feed pipe 35, they enter the packaging bag. When the packaging bag is filled with product particles of a specified weight, the packaging bag is removed from the gap between the isolation frame 34 and the protective cover 36, and is sealed by the device. Then the sub-packaged packaging bag can be transmitted through the conveyor belt 2. When the motor 37 is started, the rotating wheel 38 starts to rotate, and the rotation of the rotating wheel 38 drives the driving ring 39 to rotate, thereby causing the screw connected to the driving ring 39 to rotate. The corrugated tube 310 starts to rotate, and the rotation of the threaded tube 310 controls the threaded rod 311 to move up and down along the mounting plate 31. Since the internal threads of the threaded tube 310 on both sides of the mounting plate 31 are set in opposite directions, the rotation of the drive ring 39 will cause the threaded rods 311 on both sides of the mounting plate 31 to move in opposite directions. In conjunction with the reciprocating rotation of the motor 37, the threaded rods 311 on both sides of the mounting plate 31 start to move up and down intermittently when the motor 37 is working. When the threaded rod 311 moves downward, the adapter seat 312 at the bottom thereof is squeezed, and then the drive frame 313 is squeezed through the adapter seat 312. The drive frame 313 is limited by the protective cover 36, so when the drive frame 313 is squeezed by the adapter seat 312, its bottom will move inward. The adjusting plates 314 are deflected sideways, and the adjusting plates 314 are deflected sideways, that is, the final motion state is that the adjusting plates 314 on both sides are intermittently deflected and then reset, and then the cooperation between the two adjusting plates 314 allows the product particles to pass through the feeding tube 35 and be filled into the packaging bag in a left-right moving manner, thereby greatly improving the uniformity of distribution of the product particles in the packaging bag, and at the same time, it can also improve the placement stability of the packaging bag after the product particles are filled, and avoid the problem of the packaging bag tipping over and causing the product particles to scatter during the subsequent sealing process. When the opening of the packaging bag enters the gap between the isolation frame 34 and the protective cover 36, the electric push rod 42 is then started. When the electric push rod 42 is started, it will push the adapter frame 45 on the stabilizing frame 43 to rotate downward, and then through The mating seat 46 drives the support rod 47 to slide along the guide rod 48, and during the sliding process, the support rod 47 keeps moving downward, that is, the support rod 47 moves obliquely downward relative to the isolation frame 34, so that the two sides of the packaging bag are supported by the movement of the support rod 47, and the packaging bag has been pre-fixed through the gap between the isolation frame 34 and the protective cover 36, so that the four sides of the packaging bag are fixed during subpackaging, thereby improving the overall stability of the packaging bag when filling product particles, and when the adapter frame 45 rotates downward, the bellows 411 between the bottom plate 410 and the top plate 412 will be stretched, so that the inside is in a negative pressure state, and then the air pressure begins to be extracted from the expansion bag 415 in the slide groove 414 inside the baffle 413, that is, the expansion bag 415 begins to shrink.Then, the offset plate 416 is pulled to slide in the slide groove 414, so that the No. 1 offset hole 417 and the No. 2 offset hole 418 begin to align, and the feed pipe 35 is connected with the packaging bag, that is, the feed pipe 35 is opened synchronously when the packaging bag is supported to start conveying product particles. When the filling is completed, the electric push rod 42 is reset to drive the offset plate 416 to reset, and the feed pipe 35 is closed again, thereby greatly improving the automation level of the equipment and greatly reducing the consumption of manpower and material resources. At the same time, after the bellows 411 is stretched, air pressure will be extracted from the telescopic plate 426 at the same time, so that the telescopic plate 426 begins to shrink, thereby pulling the movable cover 420 to move to the outside of the connecting plate 419, that is, increasing the squeezing force between the rubber tube 425 and the top of the packaging bag, and finally causing the elastic tube 424 to be squeezed under the action of pressure. The deformation causes the contact area between the rubber tube 425 and the packaging bag to change from linear to planar, thereby further improving the fixing effect of the packaging bag when the packaging bag is filled with product particles, and cooperating with the support rod 47 to complete the four-way fixing. When the packaging bag is initially installed in the gap between the isolation frame 34 and the protective cover 36, the rubber tube 425 is used to achieve preliminary fixing through linear extrusion to prevent the packaging bag from falling off from the gap between the isolation frame 34 and the protective cover 36. At the same time, the movement of the support rod 47 gradually increases the squeezing effect on the packaging bag, so as to provide adjustability for the position of the packaging bag when the packaging bag is fixed in all directions, and avoid the problem that the fixing effect of the packaging bag by the rubber tube 425 is too strong at the beginning, resulting in the packaging bag being pulled and damaged by the support rod 47 due to the inaccurate installation position of the packaging bag when the support rod 47 is working.
