Description

Technical Field

[0001] The utility model relates to the technical field of packaging machines, and particularly relates to a bag supporting assembly. Background Art

[0002] The bag supporting mechanism of a packaging machine is an indispensable and important part in the packaging process. By precisely controlling the movement track and speed of the packaging bag, it realizes the stable transportation and accurate positioning of the packaging bag, providing a strong guarantee for subsequent packaging operations. The design of the bag supporting mechanism usually takes into account factors such as the material, size, shape of the packaging bag and the overall layout of the packaging machine to ensure the smooth progress of the packaging process.

[0003] In the current technical field, a bag supporting assembly of a traditional packaging machine often occupies a large amount of space resources, not only increasing the overall size of the equipment, but also restricting the flexible layout and space optimization of the production line. In addition, its load-bearing capacity is generally limited and it is difficult to meet diverse and heavy packaging requirements. Content of the Utility Model

[0004] In view of the deficiencies in the prior art, the utility model provides a bag supporting assembly.

[0005] An embodiment of the utility model provides a bag supporting assembly, including:

[0006] A base, an elevating plate is arranged above the base, and guiding mechanisms are arranged at both ends of the elevating plate;

[0007] A bag supporting mechanism, the bag supporting mechanism includes a cylinder, a connecting rod, a hopper and a supporting block. A U-shaped frame is fixedly arranged on the elevating plate, a lifting mechanism is arranged on the U-shaped frame. Rotating columns are fixedly arranged on both sides of the cylinder, and both of the two rotating columns are rotatably arranged inside the U-shaped frame. The connecting rod is fixedly arranged at the output end of the cylinder. Side plates are fixedly arranged at both ends of the bottom of the elevating plate.

Linear bearings are respectively arranged through both ends of the elevating plate, and the two guiding columns respectively penetrate through the two linear bearings and are arranged in cooperation therewith.

[0009] Furthermore, the lifting mechanism includes a motor, a reciprocating lead screw, and a shaft. The motor is installed above the base. The reciprocating lead screw passes through the U-shaped frame and is threadedly connected thereto. One end of the reciprocating lead screw is fixedly connected to one end of the shaft, and the other end of the shaft is rotatably provided on the base. A transmission mechanism is provided between the shaft and the output end of the motor.

[0010] Furthermore, the transmission mechanism includes two belt pulleys and a belt. The two belt pulleys are respectively fixedly sleeved on the output end of the motor and the shaft, and the two belt pulleys are driven by the belt.

Detailed implementation manners

[0026] The technical solutions in the present invention will be further described below with reference to the drawings and embodiments.

[0027] As Figures 1-6 shown, an embodiment of the present invention provides a bag supporting assembly, including:

[0028] A base 1, on which a plurality of mounting holes are provided through, for fixedly mounting the base 1 on a conveying device. The conveying device can drive the base 1 to move, thereby driving the tubular film material to move. Above the base 1, there is a lifting plate 3. At both ends of the lifting plate 3, there is a guiding mechanism. The guiding mechanism includes two guiding columns 2 fixedly arranged in parallel on the base 1. At both ends of the lifting plate 3, linear bearings 4 are provided through. The two guiding columns 2 respectively pass through the two linear bearings 4 and are arranged in cooperation therewith, so that the two linear bearings 4 can slide back and forth on the guiding columns 2 on the same side;

[0029] The bag supporting mechanism includes a cylinder 6, a connecting rod 7, a hopper 9 and a support block 11. A U-shaped frame 5 is fixedly arranged on the lifting plate 3, and a lifting mechanism is arranged on the U-shaped frame 5. The lifting mechanism includes a motor 13, a reciprocating lead screw 14 and a shaft rod 15. Two mounting plates 12 are fixedly arranged in parallel on the base 1, the motor 13 is fixedly arranged on the mounting plate 12, the reciprocating lead screw 14 penetrates through the U-shaped frame 5 and is threadedly connected thereto. The threaded length on the reciprocating lead screw 14 is relatively short, so that when the reciprocating lead screw 14 rotates, it can drive the U-shaped frame 5 to quickly move up and down back and forth, thereby evenly vibrating the materials inside the cylindrical film on the hopper 9. One end of the reciprocating lead screw 14 is fixedly connected to one end of the shaft rod 15, the other end of the shaft rod 15 is rotatably arranged on the base 1, and a transmission mechanism is arranged between the shaft rod 15 and the output end of the motor 13;

[0030] The transmission mechanism includes two belt pulleys 16 and a belt 17. The two belt pulleys 16 are respectively fixedly sleeved on the output end of the motor 13 and the shaft rod 15, and the two belt pulleys 16 are driven by the belt 17;

[0031] Both sides of the cylinder 6 (set as a cylinder 6 with a large load capacity, so as to ensure the ability to support heavier materials) are fixedly provided with rotating columns, and the two rotating columns are both rotatably arranged inside the U-shaped frame 5. The connecting rod 7 is fixedly arranged on the output end of the cylinder 6. A through hole is arranged through the lifting plate 3, and the connecting rod 7 penetrates through the through hole and is movably arranged, so that the connecting rod 7 can move in the through hole;

[0032] Both ends of the bottom of the lifting plate 3 are fixedly provided with side plates 8. The hopper 9 is arranged between the two side plates 8. The hopper 9 is bent and is used for placing materials with a cylindrical film. One end of the hopper 9 is fixedly provided with a round rod 10. Both ends of the round rod 10 respectively penetrate through the side plate 8 on the same side and are rotatably connected thereto. The support block 11 is fixedly sleeved on the round rod 10. The bottom end of the connecting rod 7 is hinged to the support block 11. The support block 11 and the connecting rod 7 form a link structure, so that while the cylinder 6 can drive the hopper 9 to rotate, the hopper 9 can carry heavier materials.

[0033] The detailed working process of the present utility model is as follows:

[0034] 1. During use, the cylinder 6 drives the support block 11 to rotate downward through the connecting rod 7, and the support block 11 drives the outer end of the hopper 9 to rotate upward through the round rod 10. At this time, the materials with a cylindrical film can be conveyed onto the hopper 9. At this time, the motor 13 can drive the shaft rod 15 and the reciprocating lead screw 14 to rotate through the belt 17. The reciprocating lead screw 14 can drive the lifting plate 3 to move up and down back and forth through the U-shaped frame 5, and the lifting plate 3 can drive the hopper 9 to move up and down, so as to evenly vibrate the products inside the cylindrical film;

[0035] 2. After the base 1 and the materials are transported to the set position by the conveying device, the air cylinder 6 drives the support block 11 to rotate upward through the connecting rod 7. The support block 11 drives the outer end of the hopper 9 to rotate downward through the round rod 10, pouring out the materials in the hopper 9. Finally, the conveying device drives the hopper 9 to reset, and the cycle is carried out.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
