According to the packaging materials, packaging forms, packaging items, etc., there are many classification methods for automatic packaging machines. According to the packaging form, it can be divided into bagging machines, canning machines and boxing machines. The boxing machine is to put the product into the box and fix and seal it;

[0003] When placing products on the display tray, they are often transferred by suction cups and then arranged. However, if the suction cups are used for a long time, the materials may fall off during the transfer process, especially for long and heavy products. It is impossible to provide double protection during the transfer of the materials, thereby improving the stability of the product transfer.

[0037] like Figure 1-2As shown in FIG. 5 , a gripping assembly is disposed on the outer side of the suction cup 36, and the gripping assembly includes two groups of symmetrically arranged movable rods 371 rotatably disposed on the top wall of the suction cup 36, a baffle 373 is fixedly disposed on the inner side wall of the movable rod 371 close to the suction cup 36, and the baffle 373 is in contact with the suction cup 36, a fixed wheel 372 is rotatably disposed at the bottom of the movable rod 371, and the two movable rods 371 are connected by an elastic ring 374;

[0038] The cylinder is controlled to move downward, so that the fixed wheel 372 contacts the product first, and then the suction cup 36 contacts the product, and the product is adsorbed by the suction cup 36. When the extended end of the cylinder is reset, the two movable rods 371 are quickly reset by the elastic ring 374, and the two sides of the product are clamped and fixed by the fixed wheel 372, so as to prevent the long strip product from falling due to the unstable center of gravity during the transfer process, thereby improving its stability during the transportation process;

[0043] The gear 331 is meshed and connected with the tooth plate 333, and the tooth plate 333 is controlled to move downward, and the adjustment plates 334 on both sides move downward along the sides of the placement plate 7, thereby adjusting the position of the placement plate 7 above the two unloading conveyors 61, and then the extended end of the cylinder is retracted, and the suction cup 36 moves to the top of the long product, and then the motor is controlled to rotate in the reverse direction, so that the two grabbing rods 35 are reset to prepare for the next feeding;

[0044] Embodiment 2: Figure 1 , 6 -7, the automatic packaging machine based on feed reversing arrangement adjustment proposed in this embodiment is improved on the basis of embodiment 1, a feeding conveyor 2 is arranged below one side of the limiting long plate 31, and a placing mechanism 6 is arranged below the other side of the limiting long plate 31;

[0045] like Figure 1 , 6 -7, the placing mechanism 6 includes a pair of unloading conveyors 61, a placing plate 7 is arranged above the pair of unloading conveyors 61, and a stabilizing plate is arranged on both sides of the pair of unloading conveyors 61. A limiting groove 65 is arranged above the stabilizing plate, and a two-way threaded screw rod 62 is rotatably arranged inside the limiting groove 65. Both ends of the two-way threaded screw rod 62 extend outside the limiting groove 65, and moving blocks 63 are threadedly connected on the outer walls of both sides of the two-way threaded screw rod 62, and the moving block 63 is slidably matched with the limiting groove 65, and the top of the moving block 63 is fixedly connected to the corresponding unloading conveyor 61;

[0046] like Figure 7 As shown, a handle is fixedly provided at one end of the bidirectional threaded screw rod 2 62, and the other ends of the two sets of bidirectional threaded screw rods 2 62 are connected by a transmission member 64;

[0047] It should be supplemented here that: the transmission member 64 includes two sets of transmission wheels, the transmission wheels are fixedly connected to the ends of the two-way threaded screw rod 62, and the two transmission wheels are matched through a transmission belt transmission;

[0048] When the width of the display tray 7 becomes smaller: the bidirectional threaded screw rod 2 62 is driven to rotate by the control handle, and then the two sets of bidirectional threaded screw rods 2 62 are synchronously rotated through the transmission member 64, and the corresponding two moving blocks 63 are close to each other, thereby adjusting the distance between the two unloading conveyors 61, so as to better adapt to the conveyance of display trays 7 of different widths; and the display tray 7 filled with long strip products can be packaged in the outer shell;

[0049] In the present invention, it can be seen from the combination of the first embodiment and the second embodiment that when feeding and grabbing products, the products are first adsorbed by the suction cup 36, and then clamped by the two fixed wheels 372, so that the products have double stability when they are transferred to the placement plate 7 for packaging. When feeding, the two-way threaded screw 32 is first controlled to rotate, and then the distance between the two grabbing rods 35 is adjusted to ensure that multiple groups of products are arranged and adjusted before being sent to the placement plate 7, so as to ensure the accuracy of the placement position;

[0050] In the process of placing and packaging, the position of the placing plate 7 is adjusted by two adjustment plates 334 to ensure the accuracy of the position of the placing plate 7. The present invention not only has double stability guarantee for grasping, but also in the process of placing and packaging, the arrangement and distance adjustment of the long strip products are firstly carried out, and then the position of the placing plate 7 is adjusted, thereby ensuring the accurate packaging of the long strip products, which significantly improves the production efficiency and product quality.

[0051] Working principle: When the present invention is used, first, the long strip products are placed on the feeding conveyor 2 at a fixed distance through external equipment, and the feeding mechanism 3 is moved to the top of the feeding conveyor 2 through the moving tooling 4, and the cylinder is controlled to move downward, so that the fixed wheel 372 contacts the product first, and then the suction cup 36 contacts the product, and the product is adsorbed by the suction cup 36. When the extended end of the cylinder is reset, the two movable rods 371 are quickly reset by the elastic ring 374, and the two sides of the product are clamped and fixed by the fixed wheel 372, so as to avoid the long strip products from falling due to the unstable center of gravity during the transfer process, thereby improving its stability during the transportation process;

[0052] Next, the contraction and extension of the extended end of the cylinder is controlled, and the long strip products are arranged and transferred to the top of the placement plate 7 through the mobile tooling 4. Subsequently, the motor is controlled to drive the bidirectional threaded screw 32 to rotate, so that the two grabbing rods 35 are synchronously moved toward the positioning rod 34, thereby adjusting the best placement position of the long strip products. When the long strip products are transferred to the top of the placement plate 7, the distance between the two grabbing rods 35 is adjusted again by controlling the rotation of the motor, and multiple groups of products are arranged and adjusted before feeding, thereby ensuring the accuracy of the product reversal placement position;

[0053] At the same time, the gear 331 is meshed and connected with the tooth plate 333, controlling the tooth plate 333 to move downward, and the adjustment plates 334 on both sides move downward along the sides of the placement plate 7, thereby adjusting the position of the placement plate 7 above the two unloading conveyors 61 to ensure the accuracy of the position of the placement plate 7 during unloading and packaging. Then the protruding end of the cylinder contracts, and the suction cup 36 moves to the top of the long product, and then the motor is controlled to rotate in the opposite direction, so that the two grabbing rods 35 are reset to prepare for the next feeding.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification.
