Description

Technical Field

[0001] The utility model belongs to the technical field of storage batteries, and more specifically relates to a lead paste refilling machine. Background Art

[0002] The manufacturing of battery green plates is an important process in the production of lead-acid batteries. At present, many battery manufacturers use automatic backfilling machines to backfill lead paste in the manufacturing of green plates. Using automatic backfilling machines to backfill lead paste can reduce the labor intensity of workers, and backfilling lead paste is more timely than manual work, which reduces the weight deviation of green plates caused by manual centralized backfilling of lead paste.

[0003] Since the position of the automatic backfilling machine's conveying spiral backfilling lead paste is fixed, although the weight of a single piece of raw board is reduced, the weight deviation of the two connected pieces is too large. The main reason for this problem is that the lead paste enters the paste bucket through the automatic backfilling machine's spiral, and the temperature of the lead paste increases due to the friction of the spiral, causing the apparent density to increase, resulting in a large weight deviation between the two small pieces.

[0004] As battery consistency requirements become increasingly higher, ensuring the consistency of green plate weight is the top priority for quality assurance, and ensuring the uniformity of lead paste backfill apparent density is an urgent problem that battery manufacturers need to solve.

[0024] See also Figure 1 Now, a lead paste re-paste machine provided by the utility model is described. A lead paste re-paste machine comprises a material receiving trough 1, a longitudinal conveying barrel 9 and a transverse conveying barrel 13. The upper end of the material receiving trough 1 is open and located below the plate coating machine, and is used to collect the lead paste dropped from the plate coating machine. Two mutually parallel extruding rods 2 are transversely arranged at the upper part of the inner cavity of the material receiving trough 1. The two extruding rods 2 are both rotatably arranged and there is an extrusion gap between them. A discharge port is arranged at the lower part of one side of the material receiving trough 1. A first transmission screw 3 for transmitting lead paste to the side of the discharge port is transversely arranged at the lower part of the inner cavity of the material receiving trough 1. The longitudinal conveying barrel 9 is disposed at the lower part of the inner cavity of the material receiving trough 1. The lower end is connected to the discharge port, and a second transmission screw 10 for transmitting lead paste upward is arranged inside the longitudinal conveying barrel 9. A blanking port is opened on the upper part of the side wall of the longitudinal conveying barrel 9, and a transverse conveying barrel 13 is connected to the blanking port. A discharge port is arranged at one end of the transverse conveying barrel 13, and a third transmission screw 14 for transmitting lead paste from the blanking port to the discharge port is arranged inside the transverse conveying barrel 13. A water inlet pipe 18 is connected to the side wall of the longitudinal conveying barrel 9, and the water inlet pipe 18 introduces pure water into the interior of the longitudinal conveying barrel 9.

[0025] The utility model provides a lead paste refilling machine. Compared with the prior art, the material receiving trough 1 installed below the plate coating machine collects the lead paste dropped from the plate coating machine through its upper opening. The lead paste enters the first transmission screw 3 at the lower part of the material receiving trough 1 after being squeezed by two paste squeezing rods 2. The first transmission screw 3 conveys the lead paste to the discharge port. The lead paste enters the bottom of the longitudinal conveying barrel 9 and is conveyed to the blanking port at the upper part of its side wall through the second transmission screw 10. The lead paste enters the transverse conveying barrel 13 through the blanking port, and is conveyed to the discharge port of the transverse conveying barrel 13 through the third transmission screw 14, and finally backfilled into the paste bucket of the plate coating machine. When the lead paste passes through the longitudinal conveying barrel 9, the water inlet pipe 18 introduces pure water into the longitudinal conveying barrel 9 for stirring, so that the apparent density of the backfilled lead paste is close to the apparent density of the normal lead paste dropped by the paste machine. The utility model provides a lead paste refilling machine, which can make the apparent density of the backfilled lead paste close to the normal lead paste, and ensure the consistency of the weight of the green plate.

[0026] Specifically, a first motor reducer 6 is provided on the side of the receiving trough 1 away from the discharge port, and the driving end of the first motor reducer 6 is transmission-connected to the first transmission screw 3. The first motor reducer 6 provides rotational power for the first transmission screw 3 to drive the lead paste to be transported from the receiving trough 1 to the discharge port of the receiving trough 1.

[0027] See also Figure 2 A driving gear 7 is provided at one end of the first transmission screw 3 away from the discharge port, and a driven gear 8 is provided at one end of the two paste squeezing rods 2 away from the discharge port.

Of course, the driving gear 7 can also be located in the middle of the two driven gears 8, and the meshing with any driven gear 8 is achieved through a transmission gear. While the first motor reducer 6 drives the first transmission screw 3 to rotate, the driving gear 7 of the first transmission screw 3 drives any driven gear 8 to rotate, and then drives the other driven gear 8 to rotate, thereby realizing the reverse synchronous rotation of the two paste squeezing rods 2 to squeeze the lead paste passing through the extrusion gap, and squeeze the large pieces of lead paste into small pieces.

The inner cross-section of the receiving guide pipe 17 increases from the direction close to the material discharge port to the direction away from the material discharge port, and can guide the lead paste to enter the receiving hopper 16, and then enter the transverse conveying barrel 13 through the receiving hopper 16, and finally transported to the discharge port of the transverse conveying barrel 13 through the third transmission screw 14 inside the transverse conveying barrel 13.

[0032] Preferably, there are multiple water inlet pipes 18, which are connected to the side wall of the longitudinal conveying barrel 9 at intervals from top to bottom.
