Description

Technical Field

[0001] This utility model relates to the field of PET film slitting technology, specifically to a high-efficiency PET film slitting machine. Background Technology

[0002] PET film is a thin film material made of polyethylene terephthalate. It has advantages such as light weight, high strength, good transparency, and being non-toxic and odorless, and is widely used in various fields. After PET film production, the wide PET film needs to be cut into rolls of different widths according to the customer's specific requirements to better adapt to the customer's processing equipment and production needs. A slitting machine is required for PET film slitting. The PET film slitting machine mainly consists of an unwinding mechanism, a cutting mechanism, a winding mechanism, various functional rollers, and tension control, correction control, and detection devices. The metallized film raw material released from the unwinding mechanism passes through the flattening roller, tension detection roller, guide roller, and correction system before entering the cutting mechanism for slitting. Finally, the winding mechanism winds it into film rolls that meet the standards.

[0003] However, currently, when PET film is slit, workers usually lift the PET film roll and manually place it onto the air shaft for PET film slitting and feeding. But when the PET film roll is large, the labor intensity of manual feeding is high, and safety hazards are easily caused when lifting the PET film roll. Therefore, we propose a high-efficiency PET film slitting machine. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a high-efficiency PET film slitting machine, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a high-efficiency PET film slitting machine, comprising: The base has two symmetrically distributed side plates fixedly connected to its top. Two symmetrically distributed auxiliary rollers are arranged on the opposite sides of the two side plates. A slitting component for PET film slitting is arranged between the two auxiliary rollers. A winding roller is arranged on the opposite sides of the two side plates. The feeding mechanism includes a cylinder fixedly connected to the top of the base. A connecting plate is fixedly connected to the telescopic end of the cylinder. A rotating shaft is movably connected to the top of the connecting plate via a bearing. A T-shaped seat is fixedly connected to the other end of the rotating shaft. An air expansion shaft is movably connected to the outside of the T-shaped seat via a bearing. The material pushing mechanism includes an extension bar fixedly connected to the outside of the base. A groove is provided on the top of the extension bar, and a slider is slidably connected to the inside of the groove. A bearing plate is fixedly connected to the top of the slider.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] Example 1: Reference Figure 1-3 This is the first embodiment of the present invention, which discloses a high-efficiency PET film slitting machine, comprising: The base 1 has two symmetrically distributed side plates 2 fixedly connected to the top of the base 1. Two symmetrically distributed auxiliary rollers 5 are arranged on the opposite side of the two side plates 2. A slitting component 4 for PET film slitting is arranged between the two auxiliary rollers 5. A winding roller 3 is arranged on the opposite side of the two side plates 2. The slitting component 4 includes a stepper motor fixedly connected to the outside of the side plate 2. The stepper motor is fixedly connected to a transmission rod via an output shaft, and circular blades at different distances are provided on the outside of the transmission rod.

[0020] The feeding mechanism 6 includes a cylinder 609 fixedly connected to the top of the base 1. A connecting plate 604 is fixedly connected to the telescopic end of the cylinder 609. A rotating shaft 608 is movably connected to the top of the connecting plate 604 via a bearing. A T-shaped seat 602 is fixedly connected to the other end of the rotating shaft 608. An air expansion shaft 605 is movably connected to the outside of the T-shaped seat 602 via a bearing.

[0021] Specifically, a driven gear 607 is fixedly connected to the outer side of the rotating shaft 608, and a servo motor 603 is fixedly connected to the outer side of the connecting plate 604. The cylinder 609 and the servo motor 603 are linked and controlled by the PLC. After the lifting action is completed, rotation is triggered. The servo motor 603 is fixedly connected to the driving gear 606 through the output shaft. The outer side of the driving gear 606 meshes with the outer side of the driven gear 607.

[0022] The servo motor 603 can drive the drive gear 606 to rotate via the output shaft. The rotation of the drive gear 606 drives the driven gear 607 to rotate. The rotation of the driven gear 607 drives the rotating shaft 608 to rotate. The rotation of the rotating shaft 608 drives the T-shaped seat 602 to rotate, thereby adjusting the direction of the air shaft 605 so that it can cooperate with the pushing mechanism 7 to push the PET film roll into the appropriate position outside the air shaft 605.

[0023] Specifically, a drive motor 601 is fixedly connected to the outside of the T-shaped seat 602, and one end of the air shaft 605 near the T-shaped seat 602 passes through the T-shaped seat 602 and is fixedly connected to the output shaft of the drive motor 601 through a coupling.

[0024] The drive motor 601 can drive the air expansion shaft 605 to rotate through the output shaft, so that when the PET film roll is installed on the air expansion shaft 605, the PET film roll can be driven to rotate, which makes it convenient for the circular blade to cut it.

[0025] Specifically, a limiting seat 610 is fixedly connected to the top of the connecting plate 604 away from the T-shaped seat 602, and a rectangular block 611 is movably connected to the other end of the air shaft 605 through a bearing. The rectangular block 611 is slidably connected to the inside of the limiting seat 610.

[0026] The outer side of the limiting seat 610 is provided with a groove for the rectangular block 611 to be placed. The inner side of the groove is provided with a limiting bolt for limiting the rectangular block 611. When the rectangular block 611 enters the groove, it is limited by the limiting bolt. Under the action of the limiting seat 610, the rectangular block 611 is supported from the bottom to ensure stability when cutting the PET film roll.

[0027] Example 2: Reference Figure 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that: The pushing mechanism 7 includes an extension bar 701 fixedly connected to the outside of the base 1. A groove 702 is provided on the top of the extension bar 701. A slider 707 is slidably connected to the inside of the groove 702. A bearing plate 704 is fixedly connected to the top of the slider 707.

[0028] The carrier plate 704 can move within the slide groove 702 under the action of the slider 707. When the PET film roll is placed on the carrier plate 704, the position of the PET film roll can be adjusted by pushing the carrier plate 704 so that it enters the outside of the air shaft 605, thus completing the feeding of the slitting machine.

[0029] Specifically, an arc-shaped groove 706 is provided in the middle of the top of the bearing plate 704, and a baffle 705 is fixedly connected to the top of the bearing plate 704.

[0030] The arc groove 706 facilitates the insertion of the PET film roll, ensuring that the PET film roll is located in the middle of the support plate 704 during feeding, so that the air shaft 605 can accurately penetrate the inside of the PET film roll, and the baffle 705 blocks the PET film roll from rolling up.

[0031] Specifically, a pusher plate 703 is fixedly connected to the outside of the bearing plate 704, and the pusher plate 703 is inclined and set on the outside of the bearing plate 704.

[0032] The inclined pusher plate 703 allows heavy PET film rolls to roll directly from the ground onto the support plate 704, facilitating the feeding of PET film rolls and improving feeding efficiency.

[0033] Specifically, a support leg is fixedly connected to the bottom of the extension bar 701 on the side away from the base 1, and both the slider 707 and the slide groove 702 are T-shaped.

[0034] The extension strip 701 is supported by the support legs to ensure its stability. The T-shaped design ensures that the bearing plate 704 can only move in a straight line, which facilitates the feeding of PET film rolls.

[0035] The remaining structure is the same as that in Example 1.

[0036] The workflow of this utility model is as follows: When it is necessary to feed a heavy PET film roll, the PET film roll placed on the ground is pushed onto the support plate 704 by the pusher plate 703 until the PET film roll is located in the arc groove 706 opened in the middle of the support plate 704. The limiting seat 610 is removed from the rectangular block 611. The servo motor 603 drives the drive gear 606 to rotate through the output shaft. The drive gear 606 rotates and drives the rotating shaft 608 to rotate. The rotating shaft 608 rotates and drives the T-shaped seat 602 together with the air expansion shaft 605 to rotate. When it rotates to a horizontal position with the extension strip 701, the cylinder 609 retracts until the air expansion shaft 605 is at the same height as the inner wall of the PET film roll and stops. At this time, the support plate 704 is pushed, and under the action of the slider 707 and the slide groove 702, the PET film roll moves towards the air shaft 605 until it moves to the appropriate position on the air shaft 605 and then stops. The air shaft 605 works to fix the PET film roll on its outer side. The cylinder 609 extends, driving the PET film roll to move upward until it reaches the processing height and stops. At this time, the servo motor 603 rotates in the opposite direction, driving the T-shaped seat 602 to rotate until the rectangular block 611 enters the inner side of the limiting seat 610 and stops, limiting it and completing the feeding of the slitting machine. When the slitting machine is working, the two auxiliary rollers 5 tighten the PET film, making it easier for the circular blade to slit it. The slit material is then wound up by the take-up roller 3, completing the slitting of the PET film.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
