Description

Technical Field

[0001] This utility model relates to the technical field of packaging machines, specifically to an automatic film tension adjustment device for a fully automatic pillow packaging machine. Background Technology

[0002] A fully automatic pillow packaging machine is a device used for automatic product packaging. When using a pillow packaging machine to package products such as buns, biscuits, bread, mooncakes, soft candies, as well as pharmaceuticals, daily necessities, and industrial parts, the packaging film needs to be folded to match the size of the product being packaged.

[0003] The fully automatic pillow packaging machine includes a horizontal sealing assembly, a vertical sealing assembly, a feeding tail frame assembly, a film mounting roller assembly, a film supply roller shaft assembly, a film forming hopper assembly, a suspension for adjusting film tension, and a control center. The packaging film passes through the film supply roller shaft assembly, the suspension, and the film forming hopper assembly in sequence.

[0004] Depending on the size of the packaged items, film rolls of different widths are selected to form packaging bags of different sizes. Each time a different size film roll is changed, the tension of the film needs to be readjusted by adjusting the movable roller on the suspension. Currently, this is done manually, which takes a long time and usually requires an experienced technician. Each adjustment results in the scrapping of a long section of film, which is time-consuming, labor-intensive, and wasteful of materials. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an automatic film tension adjustment device for a fully automatic pillow packaging machine, which can conveniently adjust the film tension when changing film rolls of different sizes, saving time and effort.

[0006] The technical solution to achieve the purpose of this utility model is as follows: an automatic film tension adjustment device for a fully automatic pillow packaging machine, comprising a suspension installed on the fully automatic pillow packaging machine for adjusting film tension, the suspension comprising a movable roller and two cantilever arms with elongated holes, characterized in that: the cantilever arms are fixedly provided with racks parallel to the elongated holes, the movable roller comprises a spindle and a rotating cylinder sleeved on the spindle, the spindle is provided with a gear meshing with the rack, one end of the spindle is provided with a servo motor for driving the spindle to rotate, and the servo motor is electrically connected to the control center on the fully automatic pillow packaging machine.

[0007] A handle is provided at the other end of the spindle away from the servo motor.

[0008] The cantilever is equipped with a slide rail for mounting a servo motor and parallel to the elongated hole, and the servo motor is equipped with a slider that matches the slide rail.

[0009] The automatic film tension adjustment device of this fully automatic pillow packaging machine has the following advantages: it is easy to use. When changing film rolls of different sizes, after adjusting the film tension for the first time, the data of the servo motor movement distance displayed on the control center is confirmed and saved, and the data is represented by the code of the packaging bag. Subsequently, when the code is entered on the control center, the data will pop up. After confirmation, the servo motor can move to the previously adjusted position to adjust the film tension, saving time and effort and effectively reducing material waste. If the film tension obtained from the data is deviated, the data can be fine-tuned. As long as the data is not reconfirmed and saved, each time the code is entered, the previously confirmed and saved data will pop up, making adjustment convenient. Attached Figure Description

[0010] The present invention will now be described in detail with reference to the accompanying drawings and embodiments;

[0011] Figure 1 This is a schematic diagram of the structure of this utility model;

[0013] Figure 3 This is a schematic diagram of the main structure of this utility model with the film attached. Detailed Implementation

[0014] like Figures 1-3 As shown, the automatic film tension adjustment device of the fully automatic pillow packaging machine includes a suspension 1 installed on the fully automatic pillow packaging machine for adjusting film tension. The suspension 1 includes a movable roller 1.1 and two cantilever arms 1.2 with elongated holes 1.3. The cantilever arms 1 are fixedly equipped with racks 1.4 parallel to the elongated holes 1.3. The movable roller 1.1 includes a spindle 1.11 and a rotating drum 1.12 sleeved on the spindle 1.11. The spindle 1.11 is equipped with a gear 1.5 that meshes with the rack 1.4. The tooth profile of the gear 1.5 is not shown in the figure. One end of the spindle 1.11 is equipped with a servo motor 2 that drives the spindle 1.11 to rotate. The servo motor 2 is electrically connected to the control center on the fully automatic pillow packaging machine.

[0015] A handle 1.13 is provided at the other end of the spindle 1.11, away from the servo motor 2, for easy manual adjustment.

[0016] The cantilever 1.2 is provided with a slide rail 3 for mounting the servo motor 2 and parallel to the elongated hole 1.3, and the servo motor 2 is provided with a slider 4 that matches the slide rail 3.

[0017] The film for the packaging bag is loaded and passes sequentially through the film feeding roller assembly 5, suspension 1, and film forming hopper assembly 6 of the fully automatic pillow packaging machine. The code corresponding to the packaging bag is input into the control center, and the control center displays the data for the distance that the servo motor 2 needs to move. After confirmation, the servo motor 2 can move to the previously adjusted position, thus adjusting the film tension. If the film tension obtained from the data is deviated, the data can be fine-tuned. As long as the data is not reconfirmed and saved, each time the code is entered, the previously confirmed and saved data will be displayed, making adjustment convenient.
