Description

Packing film and rewinding device used for the packing film

Technical field

The invention belongs to the technical field of packaging material production, and specifically relates to a packaging film and a rewinding device for the packaging film.

Background technique

Packing packing film is one of the commonly used packing materials for agricultural harvesting operations. Its soft texture and large single packing volume make it suitable for on-site packing of cotton and other cash crops. When packing, the packing machine uses the packing film to wrap the package, and then the packing film is cut, and finally the tape is sealed on the cutting place to complete the packing operation.

When the packaging film is being packaged, the packaging equipment needs to be braked at a specific moment. The current braking condition is based on the delivery time of the packaging film. However, due to the impression of many factors, the packaging film cannot be stopped within the specified time, so that The double-sided adhesive joint cannot be stopped at a suitable position, which causes the problem of poor packaging quality.

In addition, since the packaging film is usually a plastic film, its production process is often blown and stretched. In the final stage of production, the produced film is often wound on a paper tube to facilitate overall packaging and transport.

After the film winding is finished, the entire rewinding roller needs to be removed from the rewinding equipment, and then the paper tube and packaging film are removed from the rewinding roller. However, the problem with this process is that in order to facilitate the removal of the rewinding roll, the installation of the rewinding roll is often non-fixed installation, and its two ends are directly supported on the corresponding parts of the frame, which causes the rewinding roll It is installed in direct rolling contact with the frame bracket instead of bearings. This will cause long-term rolling friction between the rewinding roller and the frame and aggravate the loss of parts.

Detailed ways

As shown in Figures 1 to 5, the packaging film in the present invention is an improvement made on the basis of the disclosure of the invention with the application number 2017103078707. Specifically, the packaging film has continuously alternating viscous areas 22 and non-adhesive areas 23, Adjacent adhesive areas 22 and non-adhesive areas 23 are connected by a double-sided adhesive joint 24, and the bonding and working principle of the double-sided adhesive joint will not be repeated. The sticky area 22 is provided with an induction label 26 for braking by the packaging device and an electronic label 25 for recording the information of the package. The induction label 26 on the packaging film is scanned by the packaging device and the packaging device is braked to stop the double-sided tape joint. At the set position, the adhesive area 22 and the non-adhesive area 23 are narrowed at the junction of the double-sided adhesive joint 24 to form a waist structure 27.

The second improvement of the present invention lies only in the installation method of the rewinding roller 9. Specifically, a rewinding device includes a base 1, on which a left pillar 3 and a right pillar 2, and a left pillar 3 and Right pillar 2 can choose I-beam. The left pillar 3 is provided with a left platform 4, the right pillar 2 is provided with a right platform 16; the left platform 4 is provided with a sliding seat 6, and the sliding seat 6 is equipped with a left shaft sleeve 8 that can rotate around its central axis, and a base 1. There is also a driving device 1 for driving the sliding seat 6 to move along the axial direction of the left shaft sleeve 8; a driving device 2 for rotating the right shaft sleeve 10 and driving the right shaft sleeve 10 around its central axis is installed on the right platform 16; A rewinding roller 9 is connected between the shaft sleeve 8 and the right shaft sleeve 10 through a spline.

When rewinding, align the rewinding roller 9 with the left shaft sleeve 8 and the right shaft sleeve 10, and then move the sliding seat 6 to the right to move the left shaft sleeve 8 and the right shaft sleeve 10 to the corresponding ends of the rewinding roller 9 As a result, the rewinding roller 9 is installed, it can rotate under the action of torque, but cannot move axially due to the limitation of the shaft sleeve. Wind the packaging film from the conveying roller to the paper tube on the rewinding roller 9. When the rewinding of the packaging film is finished, support the rewinding roller 9 by hooks or other auxiliary equipment, and then move the sliding seat 6 to the left Move so that the left sleeve 8 is separated from the rewinding roller 9, and then the rewinding roller 9 is separated from the right sleeve 10 to be completely removed. Finally, remove the paper tube. The process is simple, efficient and reliable, which greatly improves work efficiency.

Further, the left sleeve 8 includes a shaft portion and a sleeve portion that are coaxially connected, the shaft portion of the left sleeve 8 is mounted on the sliding seat 6 through the left bearing seat 7, and the sleeve portion is provided with an internal spline; The sleeve 10 includes a shaft portion and a sleeve portion that are coaxially connected.

Similarly, the end of the connecting rod 17 can also be pivotally connected to the left upright column 2, and the end of the linear driver 18 can be pivotally connected to the base 1. In addition, both can be pivoted to the base 1. The key to realizing the linear actuator 18 to drive the connecting rod 17 is that the pivoting parts of the two need to have a distance in the horizontal direction.
