Description

Technical Field

[0001] The utility model belongs to the field of packaging machinery, in particular to a packaging film transmission mechanism. Background Art

[0002] The packaging film transmission mechanism is used for unwinding and pulling the packaging film on the packaging machine. The existing packaging film transmission mechanism includes an unwinding mechanism, a pulling mechanism, and a frame group.

[0003] The above-mentioned prior art has the following problems: under the conveyance of a series of guide die shafts of the unwinding mechanism, the packaging film is prone to material deviation, affecting production. During the use and consumption of the packaging film, the material roll gradually becomes smaller and lighter, and the driving motor to pull the packaging film is unstable. When the material is changed, the traction pressure roller needs to be manually adjusted to create a gap between the traction pressure roller and the active rubber wheel so that the material can be taken out and the packaging film can be changed. However, manually adjusting the position of the traction pressure roller delays the production rhythm. When the packaging film is changed, the packaging film needs to be cut. The packaging film has no unlimited position device, which makes the operator cut the packaging film unevenly, resulting in waste in subsequent use. Summary of the invention

[0004] The purpose of the utility model is to solve the problems existing in the above-mentioned prior art and provide a packaging film transmission mechanism which can improve production efficiency.

[0005] The utility model is implemented as follows: a packaging film transmission mechanism, a reeling mechanism and a traction mechanism are installed on a frame group; a correction group is installed on the conveying group of the reeling mechanism; an active rubber roller, a traction pressure roller, a cylinder, a slider, and a first bearing are installed on a first support frame, a driving motor is connected to the active rubber roller, a bracket of a second film guide shaft is installed on the frame group, and a first support frame is installed on the frame group; a width adjustment sensor and a width adjustment sensor bracket are installed on the frame.

[0006] Furthermore, a film winding shaft, a magnetic powder brake, a second bearing, a first film guide shaft, a film connecting plate, and a guide shaft are installed on the second support frame of the conveying group. A linear bearing is installed on the guide shaft. A first gear is installed on the film winding shaft. A second gear is installed on the shaft of the magnetic powder brake. The film connecting plate is provided with air holes and cutting grooves.

[0007] Furthermore, the housing of the electric cylinder of the deviation correction group is installed on the first bracket, and one end of the central rod of the electric cylinder is connected to the connecting rod; the connecting rod is connected to the second support frame.

[0008] Furthermore, the first shaft of the traction roller is mounted on the first roller via a third bearing.

[0009] The advantages of the utility model are:

[0010] 1. Use the deviation correction group to prevent the packaging film from deviating. The side of the packaging film passes through the inside of the U-shaped sensor. When the packaging film deviates to trigger the sensor, the electric cylinder of the deviation correction group pushes the unwinding mechanism to move and align. This solves the problem of packaging film deviation and ensures production efficiency.

[0011] 2. The side of the film roll shaft in the unwinding mechanism is connected to the magnetic powder brake through gears, and the magnetic powder brake can adjust the torque as required. This ensures that when the packaging film on the unwinding roller is consumed, the torque of the unwinding roller is consistent, so that the driving motor pulls the packaging film to run stably.

[0012] 3. When the packaging film is changed, the traction mechanism is equipped with a push cylinder, so that the traction pressure wheel can move forward and backward as required, avoiding manual adjustment and improving production efficiency.

[0013] 4. The unwinding mechanism is equipped with a film splicing plate with air holes and cutting grooves. The film splicing plate is connected to a negative pressure air source, and the packaging film is adsorbed by the air holes of the film splicing plate to ensure that the packaging film is flat. The operator can use the tool to complete the straight-line cutting of the packaging film according to the limit of the cutting groove, so that the packaging film is regular after the change of shape.

The film splicing plate 1017 is externally connected to a negative pressure air source, and the packaging film is adsorbed by the air holes of the film splicing plate 1017.
