[0025] Reference Figure 1 As shown, the ton bag feeding device provided in the embodiment of the utility model includes a sealing and cutting bag feeding component 100, a material receiving structure 200 and a feeding structure 300, as shown in FIG. Figure 2 As shown, the sealing and cutting bag unloading assembly 100 includes a pressure cover 110, a barrel 120, a driving structure 130 and a cutter 140 for cutting the inner bag of the ton bag 700. The pressure cover 110 has a first connecting hole 111 penetrating along the up-down direction thereof, and the barrel 120 is movable up and down and is arranged below the pressure cover 110. The barrel 120 has a unloading cavity 121, and the upper end of the unloading cavity 121 has a second connecting hole 111 corresponding to the position of the first connecting hole 111. 22, the barrel 120 includes an upper barrel 123 and a lower barrel 124, the upper barrel 123 is rotatably connected to the lower barrel 124, the upper end surface of the upper barrel 123 is located above the upper end surface of the lower barrel 124 so that the upper barrel 123 can press the outer bag of the ton bag 700 together with the pressure cover 110, the driving structure 130 is used to drive the lower barrel 124 to move up and down and rotate, and the tool 140 is arranged in the feeding cavity 121 and connected to the lower barrel 124; Figure 1 , 2 As shown, the material receiving structure 200 is connected to the lower end of the material discharge cavity 121 , and the material feeding structure 300 is used to place the ton bag 700 onto the barrel 120 and the pressure cover 110 .

[0026] The drive structure 130 drives the lower cylinder 124 to move up and down, and the cutter 140 can move with the lower cylinder 124. When the upper cylinder 123 and the pressure cover 110 jointly press the outer bag of the ton bag 700, the cutter 140 can simultaneously pierce the inner bag of the ton bag 700, thereby improving the efficiency of the unloading operation of the ton bag 700, thereby improving the working efficiency of the feeding station; and when the drive structure 130 drives the lower cylinder 124 to rotate, the cutter 140 can rotate with the lower cylinder 124, thereby further cutting the ton bag 700. The inner bag makes the opening of the ton bag 700 larger and the unloading speed faster, further improving the working efficiency of the feeding station; the outer bag of the ton bag 700 is pressed between the pressure cover 110 and the upper barrel 120, so that the outer bag of the ton bag is only connected to the unloading chamber 121, thereby preventing the battery powder from overflowing and thus avoiding pollution of the external environment; the barrel 120 can move up and down, so that the ton bag feeding station is not at a fixed height, thereby avoiding the situation where the ton bag 700 cannot be closely attached to the entrance when the outer bag size is small, thereby avoiding the scattering of dust.

[0027] like Figure 1 ,2 As shown, during operation, the feeding structure 300 moves the ton bag 700 to the top of the pressure cover 110, and then drives the ton bag 700 to descend a certain height, so that the bottom of the ton bag 700 passes through the first connecting hole 111 of the pressure cover 110 and the second connecting hole 122 of the barrel 120, so that the bottom of the ton bag 700 is placed in the pressure cover 110 and the lower material cavity 121, and then a part of the side edge of the outer bag of the ton bag 700 is pulled outward from the gap between the pressure cover 110 and the upper barrel 123; the driving structure 130 drives the lower barrel 124 to move upward, and the upper barrel 123 gradually abuts against the bottom surface of the pressure cover 110, thereby pressing the outer bag of the ton bag 700 between the pressure cover 110 and the upper barrel 120, and the pressure cover 110 and the upper barrel 120 are sealed together. The outer bag ensures that when the bottom of the outer bag is cut by the cutter 140, the outer bag of the ton bag 700 is only connected to the feeding chamber 121; in the process of the lower cylinder 124 moving upward, the cutter 140 follows the lower cylinder 124 to move upward, and then the cutter 140 can simultaneously pierce the aluminum foil inner bag of the ton bag 700; after the outer bag is sealed and the inner bag is pierced, the outer bag remains sealed under the clamping action of the pressure cover 110 and the upper cylinder 123, and the driving structure 130 drives the lower cylinder 124 to rotate relative to the upper cylinder 123, and the cutter 140 follows the lower cylinder 124 to rotate, and the cutter 140 further expands the gap of the inner bag of the ton bag 700, and a large amount of battery powder is discharged from the gap and collected through the material receiving structure 200.

[0028] Furthermore, if Figure 2 As shown, the aperture of the second connecting hole 122 is greater than or equal to the aperture of the first connecting hole 111, so as to ensure that the upper cylinder 123 and the pressure cover 110 can jointly clamp the outer bag of the ton bag 700 to ensure the sealing effect of the outer bag.

[0029] Furthermore, if Figure 2 , 3 As shown, the driving structure 130 includes a motor 131, a driving gear 132 and an up-and-down motion structure 133 for driving the lower cylinder 124 to move up and down. The motor 131 and the up-and-down motion structure 133 are located on one side of the lower cylinder 124. The motor 131 is connected to the driving gear 132. The outer wall of the lower cylinder 124 has an external gear 125 meshing with the driving gear 132. When the up-and-down motion structure 133 drives the lower cylinder 124 to move up and down, the external gear 125 can slide up and down relative to the driving gear 132. The driving structure 130 adopts the above structure to make the driving structure 130 simple in structure.

[0030] When sealing the outer bag, the up and down moving structure 133 drives the lower cylinder 124 to move upward, the outer gear 125 on the lower cylinder 124 moves upward relative to the driving gear 132, the lower cylinder 124 drives the upper cylinder 123 to move upward, and the upper cylinder 123 clamps the outer bag between the upper cylinder 123 and the pressure cover 110; when cutting the inner bag, the motor 131 drives the lower cylinder 124 to rotate through the driving gear 132 and the outer gear 125, and the lower cylinder 124 drives the cutter 140 to rotate; specifically, the motor 131 can be connected to the control device, and the control device controls the running time of the motor 131 so that the rotation angle of the outer gear 125 does not exceed 360 degrees, so that the aluminum foil in the inner bag of the ton bag 700 is left on the ton bag 700, and no additional processing of the aluminum foil is required in the later stage.

[0031] Furthermore, if Figure 2 As shown, the up and down movement structure 133 includes a driving device 1331 and an extension portion 1332. The extension portion 1332 is arranged on the outer wall of the lower cylinder 124. The driving device 1331 includes a moving rod 1333 for driving the extension portion 1332 to move up and down. When the extension portion 1332 rotates, the extension portion 1332 slides relative to the moving rod 1333 so that the up and down movement structure and the rotation structure on the barrel 120 do not interfere with each other.

[0032] When the lower cylinder 124 rotates, the moving rod 1333 can be slidably connected with the extension part 1332, and the driving device 1331 does not affect the rotation of the upper cylinder 123. When the lower cylinder 124 moves up and down, the driving gear 132 is slidably connected with the external gear 125 up and down, so that the driving gear 132 does not affect the up and down movement of the lower cylinder 124; specifically, the driving device 1331 is a cylinder.

[0033] Furthermore, if Figure 2 As shown, the sealing and cutting bag blanking assembly 100 also includes a fixed base plate 150 and a connecting piece 160.

The fixed base plate 150 has a through hole 151, and the lower cylinder 124 is located in the through hole 151, so that there is no contact between the fixed base plate 150 and the lower cylinder 124. The lower cylinder 124 can move up and down relative to the fixed base plate 150, so that the sealing and cutting bag blanking assembly 100 is small in size.

[0034] Further, one of the motor 131 and the driving device 1331 is mounted on the pressure cover 110, and the other of the motor 131 and the driving device 1331 is mounted on the fixed base plate 150, so that the sealing and cutting bag blanking assembly 100 is an integrated structure, which is convenient for assembly, disassembly and maintenance; specifically, Figure 2 , 3As shown, the motor 131 is installed at the bottom of the pressure cover 110, the bottom of the upper cylinder 123 is located inside the upper end of the lower cylinder 124 and is rotatably connected thereto, the external gear 125 is arranged on the outer side wall of the upper part of the lower cylinder 124, the driving device 1331 is installed on the upper end surface of the fixed base plate 150, the bottom of the extension part 1332 has a slide groove 1334, the upper end of the moving rod 1333 has a slider 1335, and the moving rod 1333 is slidably connected to the slide groove 1334 through the slider 1335.

[0035] Furthermore, if Figure 2 As shown, the upper cylinder 123 is located inside the lower cylinder 124, and a bearing 126 is provided between the upper cylinder 123 and the lower cylinder 124 so that the battery powder can be discharged smoothly; specifically, the upper and lower ends of the bearing 126 are provided with sealing covers 128, and the sealing covers 128 are used to seal the gap between the upper cylinder 123 and the lower cylinder 124 to prevent the battery powder from overflowing.

[0036] Furthermore, if Figure 1 As shown, it also includes a hammering cylinder 400, which has a hammering part 410, and the hammering part 410 faces the side wall of the ton bag 700 located on the pressure cover 110 to further increase the speed of unloading.

[0037] Furthermore, if Figure 1 , 2 As shown, the material receiving structure 200 includes a material receiving hopper 210, the lower end of the material discharge chamber 121 has a third connecting hole 127, the lower cylinder 124 and the material receiving hopper 210 are sealed and rotatably connected, and the material receiving hopper 210 is used to receive the battery powder in the material discharge chamber 121; specifically, the material receiving hopper 210 and the lower cylinder 124 can be sealed and rotatably connected via a rotary joint (not shown in the figure).

[0038] Furthermore, if Figure 2 As shown, the position of the cutter 140 corresponds to the inner bag of the ton bag 700, and the distance between the center point of the feeding chamber 121 and the inner wall of the feeding chamber 121 is greater than the distance between the center point of the feeding chamber 121 and the cutter 140, so that the opening of the ton bag 700 is larger and the feeding speed is faster, further improving the feeding efficiency.

[0039] Furthermore, if Figure 1 As shown, the feeding structure 300 includes a crossbeam 310, an electric hoist 320 movably mounted on the crossbeam 310, and a hanger 330 arranged on the electric hoist 320. The hanger 330 is used to hang ton bags 700. The electric hoist 320 facilitates the picking and placing of ton bags 700. The ton bags 700 can be hung on the hanger 330 by a hanging belt.
