DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] like Figure 1 and Figure 2As shown, a PET waste film cutting device includes a frame 1 and a glue removal component 7. A conveyor belt 3, a cutting position 2 and a transmission belt 2 4 are arranged from left to right below the surface of the frame 1, and an auxiliary component 6 is installed above the surface of the frame 1. The glue removal component 7 is installed on the right side of the auxiliary component 6, and the glue removal component 7 includes a forward and reverse motor 701, a gear 1 702, a gear 2 703, a gear 3 704, a connecting arm 705 and a wiping roller 706. The output shaft of the forward and reverse motor 701 is connected to the gear 1 702, and the gear 1 70 2 is provided with a gear 2 703 on the left side, and a gear 3 704 is connected to the left side of the gear 2 703, and a connecting arm 705 is connected to the middle of the gear 2 703 and the gear 3 704, and a wiping roller 706 is connected to the lower rear end of the connecting arm 705 through a rotating shaft, and the gear 2 703 is meshed and connected with the gear 1 702 and the gear 3 704 respectively, and the connecting arms 705 are symmetrically distributed about the vertical center axis of the sliding frame 602, and two connecting arms 705 and two wiping rollers 706 are respectively provided, and the cutting knife 605 is provided between the two wiping rollers 706.

[0022] The specific operation is as follows. After the adhesive remover is applied to the surface of the wiping roller 706, the gear 1 702 is driven to rotate by the forward and reverse motor 701, and the gear 1 702 drives the gear 2 703 to transmit and cause the gear 3 704 to rotate. The gear 2 703 and the gear 3 704 with opposite rotation directions each drive a connecting arm 705 to rotate. When the wiping roller 706 is close to both sides of the cutting knife 605, the friction between the cutting knife 605 and the wiping roller 706 can be used to remove the glue.

[0023] like Figure 1 and Figure 3 As shown, the frame 1 and the cutting position 2 are fixedly connected, the cutting position 2 is arranged between the conveyor belt 1 3 and the transmission belt 2 4, and a reeling roller 5 is installed on the right side of the transmission belt 2 4. The auxiliary component 6 is arranged above the cutting position 2, and the auxiliary component 6 includes a guide seat 601, a sliding frame 602 and a sliding pin 603, and the sliding frame 602 is slidably arranged between the guide seats 601, and the sliding pin 603 is penetrated in the sliding groove on the surface of the sliding frame 602. The auxiliary component 6 also includes a driving motor 604 and a cutting knife 605, and one end of the sliding pin 603 is connected to the driving motor 604, and the cutting knife 605 is installed at the bottom of the sliding frame 602.

[0024] The specific operation is as follows: after the driving motor 604 is started, its output shaft will drive the sliding pin 603 to rotate, and the sliding pin 603 will slide in the sliding groove on the surface of the sliding frame 602, causing the sliding frame 602 to perform vertical lifting movement with respect to the guide seat 601, so that the impact force of the cutting knife 605 when it descends will be used to cut off the PET waste film.

[0025] In summary, when the PET waste film cutting device is used, firstly, the forward and reverse motor 701 is used to drive the gear 1 702 to rotate, and the gear 1 702 drives the gear 2 703 to drive the gear 3 704 to rotate, and the gear 2 703 and the gear 3 704 with opposite rotation directions each drive a connecting arm 705 to rotate, and the wiping roller 706 is adjusted to be away from the cutting knife 605;

[0026] In the working state, the PET waste film is transported by the conveyor belt 1 3 and the transmission belt 2 4 and is rolled up by the unwinding roller 5. When it needs to be cut after being rolled up for a period of time, the driving motor 604 is controlled to drive the sliding pin 603 to rotate, and the sliding frame 602 is driven by the sliding pin 603 to perform vertical lifting movement between the two guide seats 601. During this period, the cutting knife 605 falls on the cutting position 2 along with the sliding frame 602, and the PET waste film can be cut by the impact;

[0027] When the cutting knife 605 has glue on its surface due to long-term cutting, the glue remover is applied to the surface of the wiping roller 706, and then the forward and reverse motors 701 are controlled to drive the gear 1 702 to rotate, and the gear 1 702 drives the gear 2 703 to drive the gear 3 704 to rotate, so that the two connecting arms 705 each drive a wiping roller 706 to rotate in the direction close to the cutting knife 605 until the wiping roller 706 is close to the two sides of the cutting knife 605. At this time, the driving motor 604 is used to make the cutting knife 605 move up and down, so that the friction between the cutting knife 605 and the wiping roller 706 is used to remove the glue on the surface of the cutting knife 605, thereby ensuring the cutting quality of the cutting knife 605.

[0028] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
