DETAILED DESCRIPTION

[0021] The following further describes the present application in conjunction with the drawings, and it is necessary to point out here that the following detailed description is only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application, and those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0022] Example 1

[0023] As Figures 1-5 shown, a film rack assembly for film feeding of a packaging machine includes a frame 1, the frame 1 is provided with a first film pulling assembly 3 and a second film pulling assembly 4, wherein the first film pulling assembly 3 includes a first driving roller 31, the second film pulling assembly 4 includes a second driving roller 41, the first driving roller 31 and the second driving roller 41 are each driven by a servo motor 42 provided on the frame 1, and the second driving roller 41 and the output shaft end of the corresponding servo motor 42 are connected in an open and closed manner through a clutch device 43 provided on the frame 1.

[0024] The first film pulling assembly 3 and the second film pulling assembly 4 are continuously operated, so that the packaging film has sufficient driving capacity during the film feeding process, and the second film pulling assembly 4 is provided with a clutch device, when the first film pulling assembly 3 and the second film pulling assembly 4 produce bag accumulation or excessive stretching, the power connection of the second film pulling assembly 4 is disconnected to become a free roller to eliminate the influence.

[0025] The frame 1 is further provided with a feeding tensioning assembly 2, which comprises a tensioning roller frame 21 hinged to the frame 1 and a tensioning roller 22 arranged on the tensioning roller frame 21, wherein the tensioning roller frame 21 is driven and adjusted by a tensioning cylinder 23. The feeding tensioning assembly 2 is arranged to adjust the tensioning degree of the incoming film. The tensioning cylinder 23 drives the tensioning roller frame 21 to rotate, so that the tensioning roller 22 is located at different positions, thereby adjusting the tensioning degree.

[0026] The first driving roller 31 is arranged at the rear end of the second driving roller 41 in the film feeding direction. In order to generate friction between the packaging film and the first driving roller 31, a film pressing roller is arranged to press the packaging film together with the first driving roller 31. The second driving roller 41 is the same.

[0027] The first film pulling assembly 3 further comprises a guide roller 33 and an auxiliary deviation correcting roller 34. The surface of the first driving roller 31 is provided with a first deviation correcting sleeve 32, and the surface of the auxiliary deviation correcting roller 34 is provided with a second deviation correcting sleeve 35. After the first film pulling assembly 3 pulls the packaging film, the packaging film enters the next processing stage, i.e. sealing and cutting. Therefore, the first deviation correcting sleeve 32 is arranged on the first driving roller 31 to prevent the packaging film from deviating. The guide roller 33 changes the orientation of the packaging film.

[0028] The clutch device 43 is arranged on the shaft of the second driving roller 41. The shaft of the servo motor 42 is provided with a transmission belt wheel 44, which is connected to the clutch device 43 through a belt. The clutch device 43 is arranged to intermittently disconnect the driving of the second driving roller 41. When the second driving roller 41 normally operates, it is driven together with the first driving roller 31. When there is film accumulation or excessive stretching, the connection of the second driving roller 41 is disconnected, so that it becomes a free roller, thereby eliminating the film accumulation or excessive stretching of the second driving roller 41 on the packaging film. The clutch device 43 is a prior art, which can be a pneumatic clutch. It mainly comprises a friction component, a driving component and a reset component.

[0029] The film frame assembly further comprises at least two adjusting assemblies 5. The adjusting assembly 5 comprises a pair of screw rod assemblies 52 arranged on the frame 1. The screw rod assemblies 52 are both provided with a moving seat. The two moving seats are provided with an adjusting roller 51. The shafts of the two screw rod assemblies 52 are provided with turbines. The frame 1 is rotatably provided with a synchronous adjusting shaft 53 with a worm at both ends, which is used to drive the two turbines to rotate in one direction through the worm. The adjusting roller 51 is arranged to change the angle of the packaging film as needed. The position of the adjusting roller 51 is changed to adjust the contact area of the packaging film with other different rollers.

[0030] The frame 1 is further provided with a film blowing assembly 6, which comprises an air nozzle support 61 arranged on the frame 1, a gas distribution block 62 arranged on the air nozzle support 61 and an air nozzle 63 arranged on the gas distribution block 62, which is used to blow away dust and impurities on the packaging film.

[0031] The implementation is specific to: the packaging film is unwound by the unwinding device, then passes through the tensioning roller 22 to adjust the tension, enters the second driving roller 41, and then passes through the intermediate rollers such as the adjusting roller 51 and the auxiliary deviation correction roller 34, and is pulled into the next level processing device by the first driving roller 31.

[0032] The above-described embodiments only express several implementation manners of the present application, the description is more specific and detailed, but it cannot be understood as a limitation on the patent scope of the present application. It should be pointed out that, for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
