PET Heat Shrink Battery Casing Film Blowing Machine

PET power battery casing Film Blowing Machine, this machine adopts the down blowing method (PET has strong fluidity, slow crystallization speed, and the down blowing method is more stable than flat blowing); 1、 Supporting equipment: strict requirements for drying and processing conditions 

1. Dehumidifier 85 -90℃ 

2. Dryer (4-6 hours)

3. Automatic feeding; 

2、 Blowing film machine production line: 

1. The entire host is raised by 70cm to facilitate the downblowing of the mold, which directly corresponds to the center diameter of a set of traction cooling water trays. Simply pull the film, and after the downblowing cooling is confirmed, increase preheating before flat blowing expansion (to avoid straight white lines of the casing); 

2. The extruder motor adopts a 15KW high-efficiency and energy-saving permanent magnet synchronous motor; 

3. The gearbox refueling pump maintains lubrication of the thrust shaft bearing, which is durable and durable. 

4. The barrel screw pair thread ➕ Barrier type, equipped with a 200mm cooling sleeve at the feeding port, suitable for PET modified materials; 4-stage cast aluminum heating, fan heat dissipation; 

5. Self designed and produced integrated bottom blowing mold, with 3 stages of heating, bending, mold core, and mold mouth; 

6. The control box host Siemens 10 shows that the PLC temperature control mold is fast, and the heating temperature of PET material exceeds 200 ℃ (4 sets of machine barrels and 3 sets of molds are heated in sections); 

7. A set of traction auxiliary machines is equipped with mobile tracks (three heating channels for a one-time blowing mold, equipped with three cooling water trays (fixed blowing film size) and cooling pumps, bubble control device, a pair of traction rollers, and the cooling water trays can be adjusted up and down for easy film connection. (Equipped with a circulating water pump and equipped with a 304 stainless steel external household water purifier); 

8. Two sets of traction stainless steel rubber rollers are equipped with a pair of cylinders to open, with PU rubber rollers reaching a hardness of 95 degrees. The secondary heating is carried out at 95 ℃ to circulate hot water. The front heating section and rear cooling section of the fixed diameter water jacket are equipped with adjustable devices, which can rise and fall. The water level is automatically controlled.

 9. Three sets of traction are equipped with T-shaped screw rods, and the track is moved to facilitate the use of blowing and expanding bubbles; 

10. The three sets of auxiliary machine traction rollers adopt Korean spherical bearings and gearbox sprockets, each with independent speed control display and synchronous speed control. The three sets of auxiliary machine roller speeds coordinate to increase membrane line speed and stability (high production); 

11. The winding adopts a torque motor controller, and the stainless steel plate winding disc film is curled smoothly; 

12. Machine size: 9 meters long, 1.5 meters wide, 2 meters high, with a total installed capacity of 35KW, normal power consumption of 21KW/h, weight of about 2 tons, and floor area of 27 square meters; Production capacity: 2000-3000 meters per hour; 

13. The key is that our machine has a high preservation rate, and the production of heat recovery sleeves can meet the requirements in terms of straightness, flatness, thickness uniformity, surface brightness, shrinkage rate, production capacity, etc. 

14. This machine has simple operation, stable performance, low waste, high qualification rate, reasonable design, beautiful appearance, high-quality material selection and matching to increase texture and machine service life. Machine quality is the core support point of the enterprise, and beautiful appearance is a beautiful scenery line in your workshop.

 15. PET is an internationally recognized environmentally friendly heat shrink material, with technical specifications, physical properties, application scope and usage methods, and a lateral shrinkage rate of 45-50%; Longitudinal 10-15%, width error: ± 0.03mm. Thickness tolerance: ± 0.02mm;
