[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1 to Figure 3 In an embodiment of the utility model, a ton bag feeding auxiliary device comprises a hollow funnel 1 which is wide at the top and narrow at the bottom. A feeding pipe 2 is connected to the bottom end of the funnel 1. An opening is provided on the circumferential outer wall of the feeding pipe 2. A rotating door 3 for closing or opening the opening is rotatably connected to the outer wall of the feeding pipe 2. Two symmetrically arranged limit rings 5 ​​are welded to the inner wall of the feeding pipe 2, and a gap is provided between the two limit rings 5. An anti-reverse rotation component is rotatably installed on the inner wall of the feeding pipe 2, and the anti-reverse rotation component is used to drive the clamping component to move. The anti-reverse rotation component that rotates forward is used to drive the clamping component to clamp the discharge port of the ton bag. The anti-reverse rotation component that rotates reversely is used to drive the clamping component to cancel the clamping of the discharge port of the ton bag.

[0026] In this embodiment: the bottom of the ton bag has a feeding opening made of non-woven fabric, which is generally closed by a cable tie when no material is being fed. The feeding opening of the ton bag is passed from the bottom of the funnel 1 to the feeding pipe 2 and passes between the two limiting rings 5. The position of the cable tie is controlled by the lifting device so that the cable tie is located in the gap between the two limiting rings 5.

[0027] Then open the revolving door 3. After the revolving door 3 is opened, the anti-reverse rotation component is rotated, and the anti-reverse rotation component drives the clamping component to clamp the discharge port of the ton bag. After clamping, the cable tie is untied, and then the anti-reverse rotation component is rotated in the opposite direction. The anti-reverse rotation component drives the clamping mechanism to move in the opposite direction, canceling the clamping of the discharge port of the ton bag. At this time, the material in the ton bag is discharged through the opened discharge port of the ton bag.

[0028] Please refer to Figure 3 The anti-reverse rotation assembly includes a worm 10 rotatably connected to the inner wall of the discharge pipe 2, a worm wheel 9 is meshed on the outer side of the worm 10, and a rotating shaft is interference-fitted at the center hole of the worm wheel 9; the outer peripheries of the two limit rings 5 ​​are integrally formed with a rotating seat 7, the rotating seat 7 is rotatably connected to the rotating shaft through a bearing, and a crank 11 is installed at the end of the worm 10 close to the opening.

[0029] In this embodiment: after opening the revolving door 3, the crank handle 11 is turned, the crank handle 11 rotates to drive the worm 10 to rotate, and the worm 10 drives the worm wheel 9 to rotate. At this time, the rotating shaft and the rotating seat 7 rotate relative to each other. Since the power transmission between the worm 10 and the worm wheel 9 is unidirectional, the problem that the clamping assembly cannot be effectively clamped can be effectively avoided.

[0030] Please refer to Figure 3 The clamping assembly includes a gear 8 which is interference-fitted on the outer wall of the rotating shaft, and the gear 8 and the worm gear 9 are located at different heights; racks 12 are meshed on both sides of the outer periphery of the gear 8, and the two racks 12 are offset in the upper and lower positions, and the thickness of the gear 8 is equal to the total thickness of the two racks 12, and one end of the two racks 12 is fixedly connected with a clamping plate 13; the two clamping plates 13 moving toward each other are used to clamp the discharge port of the ton bag.

[0031] In this embodiment: when the worm gear 9 rotates, the worm gear 9 drives the gear 8 to rotate synchronously through the rotating shaft, and the gear 8 drives the two racks 12 to move toward or oppositely, and the two racks 12 respectively drive the two clamping plates 13 to move toward or oppositely. When the two clamping plates 13 move toward each other to the shortest distance, the discharge port of the ton bag can be effectively clamped, which can avoid sudden discharge when opening the cable tie, causing safety risks due to the staff's hands being too close to the discharge port.

[0032] Please refer to Figure 3 Two limiting rods 6 are welded to the inner wall of the feeding tube 2, and a hole groove equal to the outer wall of the limiting rod 6 is opened inside the rack 12, and the vertical cross-sections of the hole groove and the limiting rod 6 are both elliptical.

[0033] In this embodiment, during the movement of the two racks 12 , the racks 12 slide along the outer wall of the limiting rod 6 , thereby preventing the racks 12 from moving in other directions.

[0034] Please refer to Figure 1 The non-rotating end of the revolving door 3 is detachably connected to the opening through a magnetic attraction component, which includes a positive magnet and a negative magnet. The positive magnet is connected to the non-rotating end of the revolving door 3, and the negative magnet is connected to the opening edge of the discharge pipe 2. A handle 4 is installed at one end of the outer wall of the revolving door 3.

[0035] In this embodiment, when opening the revolving door 3, the handle 4 is pulled by hand, and the handle 4 applies a pulling force to the revolving door 3. The pulling force overcomes the magnetic attraction force, and the revolving door 3 can be opened.

[0036] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
