Description

Technical Field

[0001] This utility model relates to the technical field of manual bag-fastening devices, and in particular to a manual bag-fastening device. Background Technology

[0002] In environments without an air supply, conventional cylinder-type bag clamps become ineffective. To overcome the problems of low efficiency in manual bagging and filling in environments without an air supply...

[0003] Existing manual bagging devices detach the bag before the clamping part is opened, and the opening and closing freedom of the clamping part cannot be adjusted, resulting in low bagging efficiency. There is an urgent need to provide a manual bag-fastening device to improve production efficiency, reduce labor intensity, and overcome the problem of environments without air supply. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a manual bag-fastening device, comprising:

[0005] The bucket mechanism includes an inlet end and an outlet end;

[0006] The bag clamping installation mechanism is located at the discharge end and is used for the installation of the clamping mechanism;

[0007] The bag clamping mechanism includes two annular buckles that are hinged to the bag clamping mounting mechanism and two linkage gears disposed at the hinges. The meshing of the two linkage gears enables the opening or closing of the two annular buckles. The two annular buckles include annular clamping parts and limiting parts that extend outward from the overlapping ends of the two annular clamping parts and are hinged to the bag clamping mounting mechanism. The two linkage gears are fixedly connected to the limiting parts.

[0008] A fastening mechanism is provided at the end of the annular buckle away from the bag clamping mechanism, and is used to clamp the bag opening.

[0009] In one embodiment, the bag clamping mounting mechanism includes a fixing component fixedly connected at one end to the bucket body mechanism, a connecting component hinged to the fixing component, and two parallel mounting shafts for mounting the annular buckle. The limiting portion is provided with a through hole adapted to the mounting shafts. The annular buckle is hinged to the bag clamping mounting mechanism via the mounting shafts.

[0010] In one embodiment, the fastening mechanism includes a limiting buckle extending outward from one end of one annular buckle away from the bag clamping mechanism, and a fastening component hinged to the other end of the annular buckle away from the bag clamping mechanism. The fastening component is adapted to the limiting buckle for locking and unlocking the two annular buckles.

[0011] In one embodiment, the fastening assembly includes a limiting member connected to the annular buckle via a spring, a limiting end hinged to one end of the annular buckle and adapted to the limiting member, and a drive handle disposed at the other end of the limiting end. The limiting end is provided with a limiting pin adapted to the limiting buckle. Locking is achieved when the limiting end engages with the limiting member.

[0012] In one embodiment, the annular buckle is provided with a double U-shaped rubber band to increase the friction between the bag and the annular buckle and prevent the bag from falling out.

[0013] In one embodiment, the bucket body mechanism includes a bucket body formed by welding a square top to a round bottom and a square flange disposed on top.

[0014] In one embodiment, the linkage gear is a sector gear.

[0016] Beneficial effects of this utility model

[0017] This utility model provides a manual bag-closing device, including a hopper mechanism, a bag-clamping and mounting mechanism, a bag-clamping mechanism, and a fastening mechanism. It solves the problem of low efficiency in manual bag-closing in environments without a pneumatic power source, improving production efficiency and reducing labor intensity. It has a wide range of applications and can be used with common pneumatic cylinders or motor-driven bag-clamping interfaces.

[0018] The manual bag-fastening device uses the meshing of two linked gears to limit the opening or closing of the two annular straps. When the fastening mechanism is released, only a certain initial force is needed to fully open the annular straps on both sides of the bag-clamping mechanism. The annular straps have good degrees of freedom, and their opening and closing degree can be adjusted to control the drop angle.

[0019] The fastening mechanism uses a drive handle to open and close the limiting buckle and the limiting pin. Rotating the handle by a certain angle opens the fastening mechanism. The drive handle opens one annular buckle, causing its annular clamping part to move away from the limiting part and rotate in the opposite direction. A linkage gear then drives another annular buckle to fully open the bag clamp. This opening method allows the bag to detach from the clamping mechanism and fall freely under gravity, with a falling angle of approximately 45°. The structure is simple, and the bag's falling position is controllable. Attached Figure Description

[0027] Reference Figures 1-5

[0028] This utility model provides a manual bag-closing device, including a hopper mechanism 10, a bag-clamping mounting mechanism 20, a bag-clamping mechanism 30, and a fastening mechanism 40. The hopper mechanism 10 includes an inlet end 11 and an outlet end 12; material enters from the inlet end 11 and exits from the outlet end 12 for packaging. The bag-clamping mounting mechanism 20 is disposed at the outlet end 12 and is used for mounting the clamping mechanism. The bag-clamping mechanism 30 includes two annular buckles 31 respectively hinged to the bag-clamping mounting mechanism 20 and two linkage gears 32 disposed at the hinge. The meshing of the two linkage gears 32 realizes the limiting of opening or closing of the two annular buckles 31, and realizes the controllable adjustment of the opening and closing freedom of the annular buckles 31. The two annular buckle straps 31 each include annular clamping portions 33 and limiting portions 34 extending outward from the overlapping ends of the two annular clamping portions 33, hinged to the bag clamping mounting mechanism 20. The two linkage gears 32 are respectively fixedly connected to the limiting portions 34. When the two annular clamping portions 33 are relatively far apart, the movement direction of the two limiting portions 34 is opposite to the movement direction of the two annular clamping portions 33. The fastening mechanism 40 is located at the end of the annular buckle strap 31 away from the bag clamping mounting mechanism 20 and is used to clamp the bag opening. The manual bag-fastening device achieves the opening or closing of the two annular buckle straps 31 through the meshing of the two linkage gears 32. When the fastening mechanism 40 is released, only a certain initial force is needed to fully open the annular buckle straps 31 on both sides of the bag clamping mechanism 30. The annular buckle straps 31 have good degrees of freedom, allowing adjustment of their opening and closing angles to control the drop angle.

[0029] The fastening mechanism 40 opens and closes the limiting buckle 41 and the limiting pin via the drive handle 45. When the handle rotates a certain angle, the fastening mechanism 40 opens. The drive handle 45 drives one annular buckle 31 to open, causing its annular clamping part 33 to move away from and rotate in the opposite direction to the limiting part 34. The linkage gear 32 drives another annular buckle 31 to fully open the bag clamp. This opening method allows the fastening mechanism 40 to open when the bag clamping mechanism 30 is unsupported, allowing the bag to detach from the bucket mechanism 10 and fall freely under gravity at an angle of approximately 45°. The structure is simple, and the bag's falling position is controllable.

[0030] In one embodiment, the bag clamping installation mechanism 20 includes a fixing component 21 fixedly connected to the bucket body mechanism 10 at one end, a connecting component 22 hinged to the fixing component 21, and two parallel mounting shafts 23 for mounting the annular buckle 31. The limiting part 34 is provided with a through hole adapted to the mounting shaft 23.

[0031] In one embodiment, the fastening mechanism 40 includes a limiting buckle 41 provided at one end of one annular buckle 31 that extends outward away from the bag clamping installation mechanism 20, and a fastening component 42 hinged to the other end of the annular buckle 31 that is away from the bag clamping installation mechanism 20.

[0032] In one embodiment, the fastening assembly 42 includes a limiting member 43 connected to the annular buckle 31 via a spring 46, a limiting end 44 with one end hinged to one end of the annular buckle 31 and adapted to the limiting member 43, and a drive handle 45 disposed at the other end of the limiting end 44. The limiting end 44 is provided with a limiting pin adapted to the limiting buckle 41.

[0033] In one embodiment, the annular buckle 31 is provided with a double U-shaped rubber band 36.

[0034] In one embodiment, the bucket body mechanism 10 includes a bucket body formed by welding a square top and a square flange disposed on the top.

[0035] In one embodiment, the linkage gear 32 is a sector gear.

[0036] In one embodiment, the linkage gear 32 and the limiting part 34 are fixedly connected by screws 35.
