Description

Technical Field

[0001] This utility model belongs to the field of PET polyester tape processing technology, specifically a high-speed slitting machine for PET polyester tape. Background Technology

[0002] PET polyester film, or simply PET film, is characterized by its high temperature resistance, printability, ease of processing, good voltage resistance and insulation, fire resistance (UL 94VTM-2 certified), and environmental friendliness (SGS and RoHS certified). It is a film material made from polyethylene terephthalate (PET) through extrusion to form thick sheets, which are then biaxially stretched. In the production of PET polyester tape, a high-speed slitting machine is used to cut wide PET polyester tape rolls into narrow PET polyester tapes that meet production requirements through a high-speed, precise cutting process.

[0003] In existing technology, the slitting cutters on slitting machines are generally directly fixed to the cutter shaft by rigid connectors such as bolts and clips. The relative positions between the cutters are completely locked, and the spacing cannot be flexibly adjusted according to actual production needs. They can only be slit into PET polyester strips of a single width, which has limitations.

[0004] Therefore, this utility model provides a high-speed slitting machine for PET polyester tape. Utility Model Content

[0005] To address the shortcomings of existing technology, the slitting cutters on slitting machines are generally directly fixed to the cutter shaft using rigid connectors such as bolts and clips. The relative positions between the cutters are completely locked, making it impossible to flexibly adjust the spacing according to actual production needs. This results in the machines only being able to slit into PET polyester strips of a single width, which presents limitations.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A high-speed PET polyester tape slitting machine of this utility model includes a base plate, and a slitting mechanism is provided on the top of the base plate. The slitting mechanism includes: The feeding and receiving components are located on the top of the base plate and are used for feeding and receiving materials. The cutting assembly includes a pair of upright plates fixed to the top of a base plate. A drive shaft is rotatably connected to the upright plates through a rotating hole. A cross bar is fixed between the opposite sidewalls of the pair of drive shafts. A set of cutters is slidably connected to the cross bar. An L-shaped block is fixed to the sidewall of the upright plate. A motor is fixed to the vertical sidewall of the L-shaped block. The output end of the motor is driven by one of the drive shafts. A guide roller is fixed between the opposite sidewalls of the pair of upright plates. An adjustment assembly for adjusting the set of cutters is provided between the opposite sidewalls of the pair of upright plates.

[0007] Preferably, the adjustment assembly includes a support rod fixed between a pair of upright plates, a set of concave blocks slidably connected to the support rod, and rotating rings rotatably connected to the opposite sidewalls of the concave blocks via rotating grooves, the rotating rings being fixed to the sidewall of the cutter.

[0008] Preferably, a circular block is fixed to the top of the concave block, and sliding grooves are provided on the opposite sidewalls of the pair of upright plates. A sliding block is slidably connected in the sliding groove, and a support plate is fixed between the opposite sidewalls of the pair of sliding blocks. A set of adjustment slots is provided on the support plate, and the circular block is slidably connected in the adjustment slot.

[0009] Preferably, a first rectangular strip is fixed to the top of the support plate, a second rectangular strip is fixed between the opposite sidewalls of the pair of upright plates, a first electric actuator is fixed to the sidewall of the second rectangular strip, and the telescopic end of the first electric actuator is fixed to the sidewall of the first rectangular strip.

[0010] Preferably, the feeding and receiving assembly includes a feeding unit, a receiving unit, and a pair of slide rails fixedly connected to the top of the base plate. Sliders are slidably connected to the slide rails, and a movable plate is fixedly connected to the top of the pair of sliders. The receiving unit is fixedly installed on the top of the movable plate, and the feeding unit is fixedly installed on the top of the base plate.

[0011] Preferably, a first rectangular block is fixed to the top of the base plate, a second electric actuator is fixed to the side wall of the first rectangular block, a second rectangular block is fixed to the telescopic end of the second electric actuator, and the second rectangular block is fixed to the bottom of the movable plate.

[0012] The beneficial effects of this utility model are as follows: 1. The high-speed PET polyester tape slitting machine of this utility model allows for quick adaptation to new slitting requirements without disassembling the cutters when switching slitting widths. Simply activate the first electric push rod, and adjust the cutter spacing through the linkage of the support plate and concave block. Simultaneously, fine-tune the position of the receiving unit using the second electric push rod. This eliminates the need for prolonged downtime for modifications, thus solving the problem in existing technologies where slitting cutters are typically fixed directly to the cutter shaft using rigid connectors such as bolts and clips. The relative positions of the cutters are completely locked, preventing flexible spacing adjustment based on actual production needs and limiting the slitting to a single width of PET polyester tape.

[0013] 2. The PET polyester tape high-speed slitting machine of this utility model drives the moving plate to move along the slide rail through the second electric push rod. The position of the take-up unit can be finely adjusted in real time according to the tension of the PET polyester tape released by the feeding unit and the change of the winding diameter, so as to avoid the cutter being unable to contact the PET polyester tape for slitting when the tension is insufficient.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1 to 6 As shown in the figure, a high-speed PET polyester tape slitting machine according to an embodiment of the present invention includes a base plate 1. A slitting mechanism is provided on the top of the base plate 1, including: a feeding and receiving assembly, which is provided on the top of the base plate 1 for feeding and receiving materials; and a cutting assembly, including a pair of upright plates 2 fixed to the top of the base plate 1. A drive shaft 3 is rotatably connected to the upright plates 2 through a rotating hole. A cross rod 4 is fixed between the opposite side walls of the pair of drive shafts 3 to provide radial support and drive a set of cutters 5 to rotate. A set of cutters 5 is slidably connected to the cross rod 4. An L-shaped block 6 is fixed to the side wall of the upright plate 2. A motor 7 is fixed to the vertical side wall of the L-shaped block 6. The high-speed motor 7 is the power source of the cutting assembly. The output end of the motor 7 is driven and connected to one of the drive shafts 3 in the pair of drive shafts 3. A guide roller 8, which is a circular metal roller with a smooth surface, is fixed between the opposite side walls of the pair of upright plates 2. An adjustment assembly for adjusting a set of cutters 5 is provided between the opposite side walls of the pair of upright plates 2.

[0018] The adjustment assembly includes a pair of support rods 9 fixed between the upright plates 2 to provide horizontal guidance. A set of concave blocks 10 are slidably connected to the support rods 9. Rotating rings 11 are rotatably connected to the opposite side walls of the concave blocks 10 through rotating grooves. The rotating rings 11 are fixed to the side walls of the cutter 5.

[0019] A circular block 12 is fixedly connected to the top of the concave block 10. A sliding groove 13 is provided on the opposite side walls of a pair of upright plates 2. A sliding block 14 is slidably connected in the sliding groove 13. A support plate 15 is fixedly connected between the opposite side walls of a pair of sliding blocks 14. A set of adjustment channels 16 is provided on the support plate 15. The circular block 12 is slidably connected in the adjustment channels 16.

[0020] A first rectangular strip 17 is fixed to the top of the support plate 15, and a second rectangular strip 18 is fixed between the opposite side walls of a pair of upright plates 2. A first electric actuator 19 is fixed to the side wall of the second rectangular strip 18, and the telescopic end of the first electric actuator 19 is fixed to the side wall of the first rectangular strip 17.

[0021] During operation, if it is necessary to change the slitting width, there is no need to disassemble the cutter 5. Simply start the first electric push rod 19, and adjust the spacing of the cutter 5 through the linkage of the support plate 15 and the concave block 10. At the same time, the position of the receiving unit 21 can be finely adjusted by the second electric push rod 26. This allows for quick adaptation to new slitting requirements without the need for long-term downtime for modification. This solves the problem in the existing technology where the slitting cutter 5 on the slitting machine is generally directly fixed on the cutter shaft by rigid connecting parts such as bolts and buckles. The relative position between the cutters is completely locked, and the spacing cannot be flexibly adjusted according to actual production needs. It can only slit into PET polyester strips of a single width, which has limitations.

[0022] The feeding and take-up assembly includes a feeding unit 20, a take-up unit 21, and a pair of slide rails 22 fixed to the top of the base plate 1. Slider 23 is slidably connected on the slide rails 22. A moving plate 24 is fixed to the top of the pair of sliders 23. The take-up unit 21 is fixedly installed on the top of the moving plate 24. The feeding unit 20 is used to release the PET polyester tape at a uniform speed. The released PET polyester tape first passes through the guide rollers 8 between the pair of upright plates 2. The feeding unit 20 is fixedly installed on the top of the base plate 1. The feeding unit 20 is used to wind up the PET polyester tape that has been cut.

[0023] A first rectangular block 25 is fixed to the top of the base plate 1, a second electric actuator 26 is fixed to the side wall of the first rectangular block 25, a second rectangular block 27 is fixed to the telescopic end of the second electric actuator 26, and the second rectangular block 27 is fixed to the bottom of the movable plate 24.

[0024] During operation, the moving plate 24 is driven to move along the slide rail 22 by the second electric push rod 26. The position of the take-up unit 21 can be finely adjusted in real time according to the tension of the PET polyester tape released by the feeding unit 20 and the change of the winding diameter. This avoids the cutter 5 being unable to contact the PET polyester tape for slitting when the tension is insufficient.

[0025] Working principle: Activating the first electric actuator 19, which is fixedly connected to the second rectangular bar 18, causes the telescopic end of the first electric actuator 19 to move the first rectangular bar 17, which is fixedly connected to it. Since the first rectangular bar 17 is fixed to the top of the support plate 15, the support plate 15 moves synchronously with the first rectangular bar 17. The sliding blocks 14 at both ends of the support plate 15 are respectively embedded in the sliding grooves 13 on the opposite sidewalls of the pair of upright plates 2, thus the support plate 15 moves stably along the sliding grooves 13. A set of adjustment slots 16 are provided on the support plate 15. The circular block 12 at the top of the concave block 10 is slidably connected to the adjustment slots 16. The translation of the support plate 15 pushes the circular block 12 to move through the adjustment slots 16, thereby causing the concave block 10, which is fixedly connected to the circular block 12, to slide along the support rod 9 (the support rod 9 is fixed between the pair of upright plates 2, providing a sliding guide for the concave block 10). Since the cutter 5 is rotatably connected to the concave block 10 via the rotating ring 11 on the side wall and the rotating groove on the opposite side wall, the sliding of the concave block 10 will directly drive the cutter 5 to slide along the cross rod 4. With the motor 7 driving the cross rod 4 to rotate, a set of cutters 5 can rotate and cut.

[0026] The second electric push rod 26, which is fixed to the first rectangular block 25, is activated. The telescopic end of the second electric push rod 26 drives the second rectangular block 27 to move. The second rectangular block 27 is fixed to the bottom of the moving plate 24, and the moving plate 24 is slidably connected to the slide rail 22 at the top of the base plate 1 through the bottom slider 23. Therefore, the moving plate 24 will move smoothly along the slide rail 22, thereby driving the top fixed receiving unit 21 to move closer to or away from the discharging unit 20, adjusting the spacing between them, and adjusting the tension.
