Description

Technical Field

[0001] This utility model belongs to the field of packaging production technology, and more specifically, it relates to a cigarette electrostatic film packaging and conveying structure. Background Technology

[0002] During sorting and packaging, the cigarette packs are counted and stacked, then conveyed to the packaging mechanism via a lever. After shaping, they are first wrapped with film in an east-west direction, and then conveyed to the winding mechanism for north-south winding. Compared to traditional PE film packaging, this method reduces the oven heat-shrinking process and has the advantages of being environmentally friendly and saving energy. To ensure good stacking shape, electrostatic adsorption is utilized, employing electrostatically charged cold film packaging to ensure a tight and secure stack. However, because the packaging film carries static electricity, it easily adheres to the film-feeding rollers during packaging, causing "film rewinding" and resulting in machine malfunctions and shutdowns.

[0003] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a cigarette electrostatic film packaging and conveying structure in order to achieve a more practical value. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a cigarette electrostatic film packaging conveying structure to solve the problem that the film is easily adsorbed on the film feeding roller during the film packaging process, causing the film feeding roller to "wrap film backwards" and resulting in malfunction and shutdown.

[0005] The purpose and function of this utility model's electrostatic film packaging and conveying structure for cigarettes are achieved through the following specific technical means:

[0006] A cigarette electrostatic film packaging conveying structure includes a feeding frame and a winding frame installed on a packaging machine frame. A film winding roller is rotatably connected inside the winding frame, and a film feeding roller is rotatably connected inside the feeding frame. A slider is slidably connected inside the feeding frame, and a pressure roller is rotatably connected between two sliders. The slider and the feeding frame are connected by a pressure mechanism so that the pressure roller abuts against the surface of the film feeding roller.

[0007] The feeding frame is equipped with an isolation plate located above the film feeding roller. The isolation plate has multiple arrayed openings. The film feeding roller has multiple arrayed slots along its length to form multiple roller sections. The top of each roller section protrudes from the corresponding opening.

[0008] Furthermore, the feeding frame is provided with two sets of mounting components located on both sides of the film feeding roller. Each set of mounting components includes positioning blocks installed on the two inner walls of the feeding frame, and mounting strips are provided between the two opposing positioning blocks. The two sides of the isolation plate are respectively connected to the mounting strips of the corresponding mounting components by bolts.

[0009] Furthermore, the pressure mechanism includes a top seat fixedly installed on the inner wall of the feeding rack, a connecting rod vertically passing through the top seat, the bottom of the connecting rod being connected to a slider, and a spring sleeved on the connecting rod being provided between the slider and the top seat.

[0010] Furthermore, a rocker arm is hinged to the top of the connecting rod through the top seat, and a handle extends from one side of the rocker arm.

[0011] Furthermore, a mounting plate is provided on the rear side of the feeding rack, and a guide roller is rotatably connected between the two mounting plates.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] When the film passes through the film feeding roller, both ends contact the isolation plate to form a physical barrier, which indirectly isolates the film from the film feeding roller, eliminates the phenomenon of "film wrapping backward" caused by static electricity, avoids packaging machine malfunctions and shutdowns due to static electricity, and improves equipment operating efficiency.

[0022] Example:

[0023] As attached Figure 1 To be continued Figure 3 As shown:

[0024] This utility model provides a cigarette electrostatic film packaging and conveying structure, including a feeding frame 1 and a winding frame 2 installed on the packaging machine frame. The feeding frame 1 and the winding frame 2 are two symmetrically arranged plate clamps (the packaging machine frame is omitted in the figure). A film winding roller 3 is rotatably connected inside the winding frame 2. A film roll is wound on the film winding roller 3. A film feeding roller 5 is rotatably connected inside the feeding frame 1. The film is led out from the film roll and guided and pulled by the film feeding roller 5. A slider 11 is slidably connected inside the feeding frame 1. A vertical groove 13 is opened on the feeding frame 1 in the figure. The slider 11 is slidably locked in the groove 13. A pressure roller 6 is rotatably connected between the two sliders 11. The slider 11 and the feeding frame 1 are connected by a pressure mechanism so that the pressure roller 6 abuts against the surface of the film feeding roller 5. The pressure roller 6 makes the film stick tightly to the film feeding roller 5. The rotation of the film feeding roller 5 can drive the film to move.

[0025] The pressure mechanism includes a top seat 8 fixedly installed on the inner wall of the feeding frame 1. A connecting rod 10 is vertically installed on the top seat 8. The bottom of the connecting rod 10 is connected to the slider 11. A spring 12 is sleeved on the connecting rod 10 between the slider 11 and the top seat 8. The spring 12 squeezes the slider 11 so that the pressure roller 6 can press against the film feeding roller 5, thereby allowing the film feeding roller 5 to stably and continuously convey the film.

[0026] The top of the connecting rod 10 is hinged to the top seat 8 with a rocker arm 9. A handle extends from one side of the rocker arm 9. By pressing the handle, the front end of the rocker arm 9 can be tilted upward, causing the connecting rod 10 to rise, which can disengage the pressure roller 6 from the film feeding roller 5. The handle can be lowered to reset the position.

[0027] During the packaging film conveying process, an isolation plate 7 is installed inside the feeding frame 1 above the film feeding roller 5. The isolation plate 7 has multiple arrayed openings 703. The film feeding roller 5 has multiple arrayed slots 501 along its length to form multiple roller sections. The top of each roller section protrudes from the corresponding opening 703. When the film passes through the film feeding roller 5, both ends contact the isolation plate 7, forming a physical blockage, which indirectly isolates the film from the film feeding roller 5, eliminates the phenomenon of "film wrapping and rewinding" of the film feeding roller 5 caused by static electricity, avoids the packaging machine from malfunctioning and stopping due to static electricity, and improves the operating efficiency of the equipment.

[0028] In addition, the isolation plate 7 can be tilted according to the actual conveying situation to increase the physical blocking effect.

[0029] The feeding frame 1 has a mounting plate on the rear side, and a guide roller 4 is rotatably connected between the two mounting plates. After the film is drawn out by the film feeding roller 5, it is guided by the guide roller 4 and the traction angle is adjusted to avoid the film being overly wrapped on the film feeding roller 5 or the pressure roller 6 due to different heights of the film being pulled out during subsequent packaging.

[0030] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
