TB390S Double-Sided Pasting Machine

The TB390S double-sided pasting machine is a special production equipment for lead-acid battery plate pasting, which we developed successfully based on the demands collected from domestic users. With a special structural design, the grid passes through lead paste during filling. The pasted surface is flat; no grid ribs are exposed on either side of the grid after pasting, and the paste weight on both sides is relatively uniform. The weight tolerance after pasting is precisely controlled to guarantee the consistency and stability of coated grids. It is an ideal equipment for the pasting process in battery production.

Technical Parameters

1. Applicable grid dimensions: L(220–360) mm × W(110–170) mm × T(1.2–4.5) mm
2. Grid pasting weight tolerance: For pasting weight ≤ 300 g: ±5 g per large plate; For pasting weight ＞ 300 g: ±1.5% per large plate. (Tolerance for small plate: ±1 g)
3. Grid pasting uniformity: ±0.05 mm; the mean deviation of plates from different batches shall not exceed 1/3 of the total tolerance.
4. Pasting quality: No grid ribs exposed on either side of green plates after pasting; no paste sticking or missing paste. Plates shall be flat with no surface scratches.
5. Production capacity: 80–140 plates/min
6. Paste hopper capacity: Approx. 160 kg lead paste
7. Power supply: 380 V / 50 Hz, Power rating: 15.55 kW
8. Pneumatic supply: 0.4–0.6 MPa, Air consumption: 0.2 m³/min
9. Overall dimension of main machine: L3828 mm × W1310 mm × H1915 mm
10. Equipment weight: 2.3 T

Equipment Features

1. Grid feeding mechanism: The grid feeding mechanism is extended for safer operation. Its drop height is adjustable to suit various types of grids.
2. Pasting main unit: ① Both main drive and paste hopper speed adopt frequency conversion speed regulation to realize stepless speed regulation, supporting pasting for grids of different thicknesses. ② The driven roller of the main machine is thickened, and the pasting belt is extended to 2050 mm. It avoids the common problem on other pasting machines: small-diameter driven rollers form sharp edges that stretch the pasting belt, thus effectively prolonging the service life of the pasting belt. The uniquely designed quantitative paste feeding mechanism reduces lead paste waste and lowers production costs. ③ The paste hopper adopts a double-layer structure. It prevents lead paste from entering bearings, which otherwise would cause large deviations in weight and thickness, and fracture of the stirring shaft and paste squeezing roller shaft. It effectively solves the high failure rate and difficult maintenance issues of conventional pasting machines. ④ Centralized lubrication is applied to the paste hopper, facilitating routine maintenance by operators.
3. Acid shower mechanism: ① All wetted parts in contact with acid, including screws and frames, are made of acid-resistant stainless steel. ② The acid shower roller adopts a full-length through-shaft design, avoiding shaft corrosion and fracture, which frequently occurs on machines with half shafts connected by welding. ③ Special material is used for the transition roller of the acid shower section to prevent paste adhesion.
4. Surplus paste recovery unit & acid water recovery unit: ① Used for the recovery of surplus paste and acid water.
