Description

Technical Field

[0001] This invention relates to the field of PET production technology, specifically to an automated waste removal device for the bottom film of a product. Background Technology

[0002] Polyethylene terephthalate (PET) is produced by transesterification of dimethyl terephthalate with ethylene glycol or by esterification of terephthalic acid with ethylene glycol to synthesize diethyl terephthalate, followed by polycondensation. It is a crystalline saturated polyester, a milky white or light yellow, highly crystalline polymer with a smooth, glossy surface. It is a common resin in daily life and can be classified into APET, RPET, and PETG. It exhibits excellent physical and mechanical properties over a wide temperature range, with a service temperature up to 120℃. It has excellent electrical insulation properties, even at high temperatures and high frequencies, but its corona resistance is relatively poor. It also has good creep resistance, fatigue resistance, abrasion resistance, and dimensional stability.

The bottom film containing waste material is conveyed to the winding device by a transmission device for winding.

[0073] There are three first connecting plates 320. The three first connecting plates 320 are integrally formed in a ring on the outer circumference of the drive shaft 310 at one end facing the mounting plate 110.

[0081] Example 5

[0082] Please see Figure 1-3 and Figure 5-9 The winding mechanism 500 includes a winding shaft 510, a connecting shaft 520, a cutter 530, and an electrostatic emitter 540. The winding shaft 510 is connected to the first connecting plate 320 and the second connecting plate 330 respectively through the first slot 320a and the second slot 330a. A limiting ring 510a is provided on the outer circumferential wall of the winding shaft 510, and the limiting ring 510a contacts the first connecting plate 320. The connecting shaft 520 is provided at the end of the winding shaft 510, and the connecting shaft 520 corresponds to the insulating ring 130a. A permanent magnet 520a is provided on the outer circumferential wall of the connecting shaft 520, and the permanent magnet 520a corresponds to the electromagnet 130b. The cutter 530 is provided on the outer circumferential wall of the winding shaft 510, and the electrostatic emitter 540 is provided on the outer circumferential wall of the winding shaft 510.

[0083] The take-up shaft 510 is matched with the first slot 320a and the second slot 330a. The take-up shaft 510 is placed inside the first slot 320a and the second slot 330a. The take-up shaft 510 is supported by the first connecting plate 320 and the second connecting plate 330. The pressure plate 410 is driven to move toward the second connecting plate 330 by the telescopic mechanism 420. The connecting ring 430 is sleeved on the outer circumferential wall of the take-up shaft 510. A conductive sheet is installed on the end of the take-up shaft 510 away from the mounting plate 110. After the conductive sheet on the take-up shaft 510 contacts the conductive sheet on the connecting ring 430, current is conducted.

[0084] The connecting shaft 520 is coaxially integrally formed on the take-up shaft 510 at one end facing the mounting plate assembly 100. Driven by the pressure plate 410, the take-up shaft 510 moves inside the first connecting plate 320 and the second connecting plate 330 until the connecting shaft 520 is inserted into the inner side of the insulating ring 130a. The permanent magnet 520a is uniformly embedded in the outer circumference of the connecting shaft 520 in a ring shape. The permanent magnet 520a corresponds to the electromagnet 130b. By changing the magnetic pole of the electromagnet 130b and cooperating with the connecting shaft 520, the take-up shaft 510 is driven to rotate. Its principle is the same as that of the drive of a brushless motor. The bottom film is wound up by the rotation of the take-up shaft 510.

[0085] The cutter 530 is embedded in the outer circumferential wall of the take-up shaft 510. The cutter 530 is electrically connected to the conductive sheet. After current is applied, the cutter 530 is heated. When a set of take-up shafts 510 has finished winding, the drive shaft 310 drives the take-up shaft 510 to rotate, completing the winding process and leaving the working position. The take-up shaft 510 to be wound rotates to the working position and contacts the bottom film. The bottom film is melted by the cutter 530. When the take-up shaft 510 to be wound is in the working position, the heating of the electrostatic emission rod 540 stops. The take-up shaft 510 that has finished winding rotates to the next position. When the take-up shaft 510 is in the unloading position, the telescopic mechanism 420 drives the pressure plate 410 to move away from the second connecting plate 330. The pressure plate 410 drives the take-up shaft 510 to move away from the mounting plate 110, so that the connecting shaft 520 disengages from the inner cavity of the insulating ring 130a. After the limiting ring 510a contacts the first connecting plate 320, the pressure plate 410 continues to move until the connecting ring 430 disengages from the take-up shaft 510. Under the action of gravity, the take-up shaft 510 falls off the first connecting plate 320 and the second connecting plate 330.

[0086] An electrostatic emission rod 540 is embedded on the outer circumferential wall of the take-up shaft 510. The electrostatic emission rod 540 is connected to an electrostatic generator through a wire. The electrostatic generator generates static electricity, and the electrostatic emission rod 540 emits static electricity. After the cutter 530 melts the bottom film, the bottom film is attracted by static electricity and attached to the take-up shaft 510. The take-up shaft 510 is rotated to take the film in.

A first limiting groove 610a is formed on the side wall of the first bracket 610. The second bracket 620 is disposed on the side of the mounting plate 110 and corresponds to the first connecting plate 320. A second limiting groove 620a is formed on the top of the second bracket 620. The conveyor belt 630 is disposed between the first bracket 610 and the second bracket 620 and corresponds to the drive shaft 310.

[0089] The first bracket 610 and the second bracket 620 are disposed on the side of the take-up position. The first bracket 610 corresponds to the second connecting plate 330, and the second bracket 620 corresponds to the first connecting plate 320. One end of the take-up shaft 510 away from the connecting shaft 520 is inserted into the inner side of the first limiting groove 610a, and the take-up shaft 510 is inserted into the inner side of the second limiting groove 620a. The first limiting groove 610a and the second limiting groove 620a guide the take-up shaft 510, and the conveyor belt 630 transports the take-up shaft 510 so that the take-up shaft 510 can be accurately transported to the inner side of the first slot 320a and the second slot 330a, so that the limiting ring 510a is between the first connecting plate 320 and the mounting plate 110.

[0090] After the take-up shaft 510 enters the inner side of the first slot 320a and the second slot 330a, the telescopic mechanism 420 drives the pressure plate 410 to move toward the second connecting plate 330, so that the connecting ring 430 is engaged with the outer circumferential wall of the take-up shaft 510. The connecting ring 430 and the take-up shaft 510 are connected by a bearing. The pressure plate 410 drives the take-up shaft 510 to move toward the mounting plate 110 until the connecting shaft 520 is inserted into the inner cavity of the insulating ring 130a.
