Description

Technical Field

[0001] The utility model relates to a ton bag mouth tightening and exhausting device, belonging to the technical field of ton bag mouth tying. Background Art

[0002] Ton bags are usually used for powder filling. In the field of modern logistics and warehousing, powder filling is usually carried out through automated packaging lines. After filling, the bags are tied. There are multiple ways to tie the bag mouths, including suturing and tying. The tying method is more suitable for reuse of ton bags, that is, after one packaging use, it can be tied and sealed again. Generally, the tying operation is done manually, which has low work efficiency and high labor intensity. In addition, the powder particles are easily dispersed into the air, which is harmful to workers.

[0003] A Chinese invention patent with publication number CN117963261A discloses a ton bag closing machine, including a bag opening tightening device, including two swing frames 21, a closing push plate 23 protruding inward from the swing frame 21, and the closing push plate 23 is perpendicular to the limit plate, and the movement directions of the closing push plates 23 are opposite. When the bag is tied, the swing frame 21 of the bag opening tightening device embraces the bag opening of the ton bag under the drive of the swing drive 22, and then the two closing push plates 23 are driven by the push plate drive 24 to approach each other to embrace the flat bag opening together.

[0004] The above-mentioned bag mouth closing machine has the following disadvantages in the closing process: after the powder is filled into the ton bag, the bag mouth is directly closed and tied by the push plate, resulting in the ton bag being loosely tied and the tying quality being poor. In addition, the ton bag also seals in air, which is inconvenient for the storage and transportation of the ton bag.

[0005] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] In view of the deficiencies in the background technology, the utility model provides a ton bag mouth tightening and exhausting device, which can tighten the mouth of the ton bag filled with powder and squeeze out the air in the ton bag, so that the ton bag after the mouth is tied is tighter, which is convenient for the storage and transportation of the ton bag.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] A ton bag mouth tightening and exhausting device comprises a mounting bracket, a central control rotating platform is mounted on the mounting bracket, a rotating body is fixed with a turntable, a lower surface of the turntable is fixed with a clamping claw driving cylinder, and a plurality of clamping claws are evenly distributed around the clamping claw driving cylinder;

[0009] A push plate is fixed on the telescopic rod of the clamp driving cylinder. The upper end of the clamp is hinged on the lower surface of the rotating disk. The clamp is connected to the push plate. The push plate moves up and down to drive the clamp to open and close.

[0010] Furthermore, a plurality of support rods are evenly distributed around the push plate, and the support rods are arranged in one-to-one correspondence with the clamping claws. The first ends of the support rods are hinged to the clamping claws, and the second ends of the support rods are hinged to the push plate.

[0011] Furthermore, the clamp includes a claw rod and an upper bending section extending inward from the top of the claw rod, the upper bending section is arranged at a certain angle to the claw rod, the first end of the support rod is hinged at the bending point of the claw rod and the upper bending section, and the end of the upper bending section extending inward is hinged on the turntable.

[0012] Furthermore, the clamping claw also includes a lower clamping section arranged at the lower end of the claw rod.

[0013] Furthermore, the support rod is in an arc shape with the middle section convex toward the bottom.

[0014] Furthermore, a plurality of support columns are vertically provided on the lower surface of the turntable, and the support columns are arranged in a one-to-one correspondence with the clamping jaws, and the lower ends of the support columns are hinged to the ends of the upper bending sections of the clamping jaws extending inward.

[0015] Furthermore, it also includes a vertically arranged electric cylinder, and the mounting bracket is mounted on a sliding seat of the electric cylinder.

[0016] Furthermore, the central control rotating platform is driven by a driving motor.

[0017] Compared with the prior art, the utility model has the following advantages after adopting the above technical solution:

[0018] When the push plate moves downward, the support rod pulls the clamp downward so that the clamps are close together and can clamp the bag opening. Driven by the central control rotating platform, the clamps rotate. At the same time, the electric cylinder drives the mounting bracket to move downward, so that the clamps clamp the bag opening and rotate while moving downward to remove the air in the bag and twist the bag opening into a columnar shape, so that the tied ton bag is tighter and easier to store and transport.

[0025] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0026] like Figure 1-3 As shown, the utility model provides a ton bag mouth tightening and exhausting device, comprising a mounting bracket 2, a central control rotating platform 3 is mounted on the mounting bracket 2, the central control rotating platform 3 is driven by a driving motor 4, a turntable 10 is fixed on the rotating body, a clamp driving cylinder 9 is fixed on the lower surface of the turntable 10, and a plurality of clamps 6 are evenly distributed on the circumference of the clamp driving cylinder 9;

[0027] A push plate 8 is fixed on the telescopic rod of the clamp driving cylinder 9. The upper end of the clamp 6 is hinged on the lower surface of the turntable 10. The clamp 6 is connected to the push plate 8. The push plate 8 moves up and down to drive the clamp 6 to open and close, so as to grasp the bag mouth of the ton bag. Then, the central control rotating platform 3 drives the turntable 10 to rotate, thereby driving the clamp 6 to rotate, so as to tighten the bag mouth of the ton bag.

[0028] A plurality of support rods 7 are evenly distributed around the push plate 8 , and the support rods 7 are arranged in one-to-one correspondence with the clamping claws 6 . The first ends of the support rods 7 are hinged to the clamping claws 6 , and the second ends of the support rods 7 are hinged to the push plate 8 .

[0029] The clamping claw 6 includes a claw rod 601 and an upper bending section 602 extending inward from the top of the claw rod 601, and the upper bending section 602 is arranged at a certain angle to the claw rod 601. The first end of the support rod 7 is hinged at the bending point of the claw rod 601 and the upper bending section 602, and the end of the upper bending section 602 extending inward is hinged on the turntable 10.

[0030] The clamping claw 6 further includes a lower clamping section 603 disposed at the lower end of the claw rod 601 .

[0031] The support rod 7 is in an arc shape with the middle section convex toward the lower side.

[0033] The utility model further comprises a vertically arranged electric cylinder 1 , and the mounting bracket 2 is mounted on a sliding seat of the electric cylinder 1 .

[0034] The specific working principle of the utility model:

[0035] The electric cylinder 1 drives the mounting bracket 2 to move up and down, thereby driving the clamping jaws 6 to move up and down. When the clamping jaws drive the cylinder 9 to extend and retract, it drives the push plate 8 to move up and down. When the push plate 8 moves up, the support rod 7 pushes the clamping jaws 6 upward to move upward, so that the clamping jaws 6 are separated. When the push plate 8 moves down, the support rod 7 pulls the clamping jaws 6 downward to move downward, so that the clamping jaws 6 are close together to clamp the bag opening. Driven by the central control rotating platform 3, the clamping jaws 6 rotate. At the same time, the electric cylinder 1 drives the mounting bracket 2 to move downward, so that the clamping jaws 6 clamp the bag opening while rotating and moving downward, the air in the bag is discharged, and the bag opening is twisted into a columnar shape, so that the tied ton bag is tighter, which is convenient for the storage and transportation of the ton bag.
