Description

Technical Field

[0001] The utility model relates to the technical field of packaging machinery, in particular to a conveying mechanism of a bagging machine. Background Art

[0002] Currently, factories have achieved automated product packaging, typically using various packaging machines for production lines. Patent application number CN201920592688.5 discloses an automatic sealing packaging machine that includes a frame, a feed platform, a discharge platform, a film placement assembly, a knife holder assembly, and a waste material collection assembly to package products. The feed platform includes a feed frame, a photoelectric eye bracket fixed to the left side of the feed frame, and a feed motor and feed conveyor roller fixed to the right side of the feed frame. The feed motor and the feed conveyor roller are connected by a transmission chain. The feed motor drives the feed conveyor roller to rotate, causing the product to be wrapped to move to the left.

[0003] The above-mentioned feeding platform has the following shortcomings in the actual production process: 1. The feeding platform lacks a mechanism for conveying film. After the film is output from the film unwinding component, it can only be moved forward with the help of the knife holder component. When the equipment is used to package large products, due to the large film width, the resistance to film movement increases, and the knife holder component alone cannot pull the film smoothly, resulting in uneven film feeding and possible jamming; 2. The position of the adjustment platform is fixed and cannot be adjusted. When there is a deviation between the product conveying direction, the film unwinding direction and the knife holder component, it cannot be adjusted quickly. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a conveying mechanism of a bagging machine in view of the above-mentioned deficiencies in the prior art, so as to ensure smooth and unobstructed feeding of the film and reduce the jamming phenomenon.

[0006] The utility model with the above characteristics: By adding a film driving mechanism and using the combination of the active film driving roller and the passive film driving roller, it can provide an additional driving force when the film moves, effectively solving the problems of large film width and difficult movement during the packaging of large products, ensuring that the film moves smoothly during the feeding process, reducing jamming phenomena, and improving the overall packaging efficiency; the setting of the clutch assembly enables the active film driving roller to be attached to or separated from the passive film driving roller according to actual conditions, realizing the controllability of film movement, cooperating with subsequent processes, and reducing energy consumption.

[0007] A further setting of the utility model is that: the clutch assembly includes clutch swing plates respectively arranged on both sides of the driving seat and hinged thereto, a clutch power member for driving the clutch swing plates to rotate around the hinge center, the two ends of the active film driving roller are installed on the clutch swing plates, and the film driving motor is arranged on one of the clutch swing plates.

[0008] The utility model with the above characteristics: The clutch power member can quickly drive the clutch swing plates to rotate around the hinge center, thus quickly realizing the attachment or separation of the active film driving roller and the passive film driving roller. This fast clutch method makes the conveying mechanism adapt to the actual production situation of the film; setting the film driving motor on the clutch swing plate to rotate together with the active film driving roller ensures smooth driving.

[0009] A further setting of the utility model is that: the clutch swing plate is provided with a roller connecting portion connected to the active film driving roller, a driving hinge portion hinged to the driving seat, and a sliding connecting portion slidably connected to the driving seat. The roller connecting portion is higher than the driving seat. A first connecting shaft is provided between the driving hinge portion and the driving seat. Sliding grooves are respectively arranged on the two side walls of the driving seat. A second connecting shaft connected to the sliding connecting portion is inserted through the two sliding grooves. The output end of the clutch power member is connected to the second connecting shaft, and the end away from the output end is hinged to the driving seat. The clutch power member is selected as a cylinder.

[0010] The utility model with the above characteristics: Through the cooperation of the sliding connecting portion and the sliding grooves on the driving seat, it provides a stable guide for the rotation of the clutch swing plates; the clutch power member is hinged to the driving seat, so that it also swings when driving the second connecting shaft to move along the sliding groove, with high flexibility and suitable for the complex movement trajectory of the clutch assembly; the clutch power member is selected as a cylinder, which has the advantages of fast response speed, precise control, and simple maintenance.

[0011] A further setting of the utility model is that: the output end of the film driving motor is provided with an active synchronous pulley, one end of the active film driving roller is provided with a passive synchronous pulley, and synchronous rotation is achieved between the active synchronous pulley and the passive synchronous pulley through a synchronous belt.

[0012] The utility model with the above characteristics: The film driving motor drives the active film driving roller to rotate through the synchronous pulley assembly. This transmission method will not slip during operation, can ensure the precise synchronization between the film driving motor and the active film driving roller, and is more suitable for the situation where the film driving motor and the active film driving roller rotate.

[0013] A further setting of the utility model is that at least one set of linear guide rail assemblies are slidably connected below the feeding frame and the driving seat, and the length direction of the linear guide rail assembly is parallel to the axis direction of the passive film driving roller.

[0014] The utility model with the above characteristics: By setting the linear guide rail assembly, the installation positions of the feeding frame and the driving seat can be adjusted accordingly.

The active film driving guide roller a42 and the film driving motor a43 are arranged on the driving seat a44 through the clutch assembly a45. At least one set of linear guide rail assemblies a48 are slidably connected below the feeding frame a1 and the driving seat a44. The length direction of the linear guide rail assemblies a48 is parallel to the axis direction of the passive film driving guide roller a41.

[0021] The clutch assembly a45 includes clutch swing plates a451 arranged on both sides of the driving seat a44 and hinged to it, and a clutch power member a452 for driving the clutch swing plates a451 to rotate around the hinge center. Both ends of the active film driving guide roller a42 are installed on the clutch swing plates a451. The film driving motor a43 is arranged on one of the clutch swing plates a451. The clutch swing plates a451 are provided with a guide roller connection portion a4511 connected to the active film driving guide roller a42, a driving hinge portion a4512 hinged to the driving seat a44, and a sliding connection portion a4513 slidably connected to the driving seat a44. The guide roller connection portion a4511 is higher than the driving seat a44. A first connecting shaft a453 is provided between the driving hinge portion a4512 and the driving seat a44.
