DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0032] See also Figure 1 and Figure 2The stacking and flattening device based on hot stamping for aluminum-plastic bag production shown in the figure includes a stacking platform 1, two arc-shaped track rods 2 are fixed at one end of the stacking platform 1, and the arc-shaped track rods 2 are provided with a bonding plate 3 for hydraulic cylinder drive, and also include a transfer device 4 installed between the two arc-shaped track rods 2 and a support frame 8 installed on the outside of the stacking platform 1, and a plurality of isolation plates 5 are slidably sleeved on the outside of the two arc-shaped track rods 2, an insertion port 6 is opened in the isolation plate 5, and a guide plate 7 is fixed on the outside of the insertion port 6, a threaded rod 9 is rotatably installed on one end of the support frame 8, and a sliding rod 10 is fixed on the other end of the support frame 8, a moving seat 11 slidably connected to the sliding rod 10 is threadedly sleeved on the outside of the threaded rod 9, and a flattening mechanism 12 is installed on the moving seat 11, and a driving motor 13 fixed to the outer end of the threaded rod 9 is fixed on the outside of the support frame 8.

[0033] It should be noted that: a hot stamping die can be installed on the designed stacking platform 1, so that hot stamping can be directly performed after the stacking is flattened.

[0034] It is worth noting that the isolation plate 5 is made of plastic with a certain flexibility, so that when it is attached to the multi-layer material, the material can be prevented from being damaged.

[0035] See also Figure 6 , Figure 7 and Figure 10-11 The flattening mechanism 12 shown in the figure includes a flattening motor 14 fixed to one end of a moving seat 11, the moving seat 11 is an L-shaped structure, and the flattening motor 14 is installed at the vertical end of the moving seat 11, and a plurality of threaded sleeves 15 are rotatably inserted into the vertical end of the moving seat 11, and a plurality of flattening rods 16 are threadedly inserted in the plurality of threaded sleeves 15, and a linkage 17 is installed on the outer side of the threaded sleeve 15, and a plurality of flattening rods 16 are slidably sleeved with a support seat 18 at the tail end, and the flattening motor 14 is installed at the rear end of the moving seat 11. A push rod 19 is fixed to the output end of the machine 14 through a coupling, and the push rod 19 is threadedly connected to the support seat 18. The flattening rod 16 has a hollow tube structure inside, and a plurality of air inlet holes 20 are equidistantly opened on the outside of the flattening rod 16. The front end of the flattening rod 16 is a conical structure, and a limit groove 21 is opened on the outside of the flattening rod 16. A limit strip 22 adapted to the limit groove 21 is fixed on the inside of the support seat 18, and a negative pressure component 23 is installed on the outer end of the support seat 18;

[0036] It should be noted that: by rotating the flattening motor 14 and cooperating with the linkage 17, the multiple threaded sleeves 15 rotate synchronously, so that the multiple flattening rods 16 can be synchronously moved and inserted into the guide plate 7 and extended into the insertion port 6. Then, the driving motor 13 rotates to drive the movement of the moving seat 11, thereby cooperating with the flattening rods 16 to push the multiple materials in sequence, realize the flattening action, and reduce the occurrence of wrinkles.

[0037] It is worth noting that the linkage member 17 includes a plurality of linkage gears 31, which are meshed with each other and are respectively installed on the outer sides of the output ends of the plurality of threaded sleeves 15 and the flattening motor 14. The plurality of linkage gears 31 are meshed with each other and can realize synchronous rotation, wherein the inner threads of adjacent threaded sleeves 15 face opposite directions, thereby ensuring that the adjacent flattening rods 16 can move synchronously.

[0038] Also, see Figure 3-Figure 5 The transfer device 4 shown in the figure includes an outer cylinder 32 and an inner rod 33, the inner rod 33 is rotatably inserted into the outer cylinder 32, and an adjustment port 34 is opened on the outer side of the outer cylinder 32, a docking plate 35 is fixed on the outer side of the adjustment port 34, and two adsorption plates 36 are installed at both ends of the docking plate 35 through a rotating shaft, and adsorption disks 37 are installed at the outer ends of the two adsorption plates 36, and an adjustment column 38 is slidably inserted at the other end, and thread grooves facing opposite directions are opened on the outer sides of the two ends of the inner rod 33, and a moving platform 39 is threadedly inserted at both ends, and the moving platform 39 is rotatably connected to the tail end of the adjusting column 38, support legs are connected at both ends of the outer cylinder 32 through bearing sleeves, and a rotating motor 40 is fixed on the outer side of one of the support legs through a motor frame, and the output end of the rotating motor 40 is fixed to the outer end of the inner rod 33 through a coupling, and a rotating member 41 is installed at the end of the outer cylinder 32 away from the rotating motor 40;

[0039] It should be noted that: by rotating the motor 40, the inner rod 33 is driven to rotate, and the rotating part 41 is cooperated to realize the rotation of the outer cylinder 32. The rotation of the inner rod 33 can drive the two moving platforms 39 to move synchronously in opposite directions, thereby controlling the angle deviation of the adsorption plate 36, so that the adsorption plate 37 is separated from the isolation plate 5, satisfying the action of adsorption, movement and lowering of the isolation plate 5.

[0040] It is worth noting that the negative pressure gas required by the adsorption disk 37 is provided by external negative pressure equipment.

[0041] Also, see Figure 5 The rotating member 41 shown in the figure includes a connecting gear 42 rotatably mounted through a connecting frame, a gear rod 43 meshing with the connecting gear 42 is fixed to the outer end of the inner rod 33, and an inner gear ring 44 meshing with the connecting gear 42 is fixed to the inner wall of the outer cylinder 32;

[0042] It should be noted that: through the rotation of the inner rod 33, in cooperation with the action of the connecting gear 42, the inner gear ring 44 can be driven to rotate, thereby driving the outer cylinder 32 to rotate, and the adsorbed isolation plate 5 is moved to the stacking platform 1 through the arc track rod 2. After moving to the stacking platform 1, the two adsorption plates 37 retract at an angle, thereby separating from the isolation plate 5. At this time, the isolation plate 5 is pressed onto the stacking platform 1 by moving the bonding plate 3 downward, thereby realizing the docking and pressing of the multi-layer materials.

[0043] The principle of stacking and flattening aluminum-plastic bags: First, layers of materials are placed on the stacking platform 1 in sequence through external equipment. Each time a layer of material is stacked, the outer cylinder 32 in the transfer device 4 is rotated to rotate the adsorbed isolation plate 5 through the arc track rod 2, so that the isolation plate 5 moves along the arc track rod 2 to the stacking platform 1, and then squeezed through the bonding plate 3. Each time a layer of material is attached, the isolation plate 5 is driven by the transfer device 4 to rotate and bond, so that the isolation plate 5 is sandwiched in the middle of the multi-layer material. Then, the flattening motor 14 is rotated to drive multiple linkage gears 31 to rotate synchronously, so that multiple threaded sleeves 15 are rotated, and multiple flattening rods 16 are driven to move synchronously and inserted into the insertion port 6. Then, the driving motor 13 is used to drive the threaded rod 9 to rotate, so that the moving seat 11 rotates along the slide rod 10, thereby realizing the flattening operation of the multi-layer material and reducing the generation of wrinkles.

[0044] In addition, in this solution, a stacking and expansion method based on hot stamping for the production of aluminum-plastic bags comprises the following steps:

[0045] A. A hot stamping die is installed on the stacking platform 1. When the personnel place the multi-layer materials required for the aluminum-plastic bag layer by layer, after placing each layer of materials, a separation plate 5 is moved through the transfer device 4 so that there are separation plates 5 in the multi-layer materials, and then they are pressed together through the laminating plate 3;

[0046] B. The inner part of the multilayer material is flattened by inserting a plurality of flattening rods 16 into the insertion opening 6 in the isolation plate 5 and then moving the plurality of flattening rods 16;

[0047] C. After flattening, hot pressing is performed using a hot stamping die installed on the stacking platform 1. Example 2

[0048] See also Figure 8 and Fig. 9 , this embodiment further explains Example 1, the negative pressure assembly 23 shown in the figure includes an L-shaped plate 24, the L-shaped plate 24 is fixed to the support seat 18 through a connecting plate, and a rotating gear 25 is rotatably installed on the outer side of the L-shaped plate 24, a limiting opening 26 is opened on the outer side of the push rod 19, and the rotating gear 25 is sleeved on the outer side of the push rod 19 and engaged with the limiting opening 26, a speed change gear 27 meshing with the rotating gear 25 is rotatably installed on the outer side of the L-shaped plate 24, and a negative pressure wind wheel 28 is fixed on the outer side of the central axis of the speed change gear 27, a support plate 29 is fixed on the L-shaped plate 24, and a negative pressure cylinder 30 sleeved on the outer side of the negative pressure wind wheel 28 is fixed through the support plate 29, the outer end of the negative pressure cylinder 30 is connected to the tail ends of multiple flattening rods 16 through a hose, and a moving opening for moving the push rod 19 is opened on the support plate 29;

[0049] It should be noted that: by rotating the designed flattening motor 14, the push rod 19 is driven to rotate, so that the support seat 18 can be controlled to move along the moving seat 11, and the flattening rod 16 is slowly pushed into the insertion port 6, and then the push rod 19 is rotated to drive the rotating gear 25 and the speed gear 27 to mesh and rotate with each other, so that the negative pressure wind wheel 28 rotates, so that negative pressure can be generated in the multiple push rods 19, and air is sucked through the air inlet 20 to adsorb the multi-layer material, which is convenient for the subsequent flattening operation;

[0050] It is worth noting that: during adsorption, a section of the flattening rod 16 is first slowly extended, and then the moving seat 11 is driven by the driving motor 13 to move, so that a section of the flattening rod 16 begins to adsorb the multi-layer material, and then slowly extends, adsorbing the multi-layer material and moving slowly, which can better flatten the multi-layer material and improve the flattening effect. At the same time, in order to avoid too tight adsorption with the multi-layer material, a groove is opened on the outside of the flattening rod 16 at the position corresponding to the air inlet 20. Example 3

[0051] See also Figure 8 This embodiment is further described for other embodiments. A limiting frame 45 that fits the moving seat 11 is fixed to the bottom end of the L-shaped plate 24 shown in the figure.

[0052] It should be noted that the design of the limit frame 45 can make the movement of the L-shaped plate 24 smoother and more stable.
