Embodiment 1

[0018] Example 1 as figure 2 As shown, there are two bosses and two grooves arranged alternately in each row on the peripheral surface of its driving squeeze roller 7 and driven squeeze roller 3 . The boss of the active squeeze roller 7 corresponds to the groove position of the driven squeeze roller 3, to ensure that the boss of the active squeeze roller 7 can be just right when the active squeeze roller 7 and the driven squeeze roller 3 roll against each other synchronously. Align the groove of the driven squeeze roller 3.

[0019] Example 1 as image 3 As shown, when the lead cake 14 enters the joint between the active extrusion roller 7 and the driven extrusion roller 3, the driven extrusion roller 3 will rotate due to the power mechanism driving the active extrusion roller 7 to rotate through the engagement of the transmission gear 4. Synchronously rotating with the active squeeze roller 7, the lead cake 14 is squeezed into the groove to become lead pellets, and then pu...

Embodiment 2

[0020] Embodiment 2 is basically the same as Embodiment 1, except that the curved surfaces of the two extrusion rollers are distributed with concave and convex staggered bosses and grooves of different sizes, and the bosses and grooves in the middle of the curved surface of the extrusion rollers are The grooves have the same size, but the bosses and grooves on both sides of the curved surface of the extrusion roller are larger than those in the middle, because the lead cake 14 is not completely regular in size, so the two sides of the curved surface of the extrusion roller When the boss and the groove are larger than the boss and the groove in the middle, the leftover material can be fully used, saving raw materials. The difference between embodiment 2 and embodiment 1 is that the ejector mechanism is composed of an eccentric cam and ejector rods; or the ejector rod mechanism is formed by a spring connected to the bottom of each ejector rod. In the present invention, the lead ...

Abstract

The invention belongs to a design method and a device for a machine carrying out granule cutting to soft metal in a cold state, in particular to a design method and a device relating to a lead cake granulator which squeezes a lead cake into granules via two squeezing rollers contra-rotating synchronously. A power mechanism is fixed on a machine frame (1) of the lead cake granulator adopted by the invention, and is in the transmission connection with a granule cutting mechanism via a transmission mechanism; the granule cutting mechanism is provided with the two squeezing rollers contra-rotating synchronously, and accidented and staggered dummy clubs and flutes are distributed on the arc surfaces of the squeezing rollers. The lead cake granulator can directly cut lead cakes into lead granules in the cold state, and the energy is saved, the lead material wastage is lowered, and the environmental pollution is reduced.

Description

technical field [0001] The invention belongs to a design method and device for particle segmentation equipment for soft metals in a cold state, in particular to a lead cake granulator and a design method thereof. technical background [0002] At present, in the lead-acid battery manufacturing industry, the lead powder machine that produces lead powder needs to use about 50g of lead pellets as raw materials. The traditional way to obtain lead pellets is to melt the lead ingots (each ingot weighs 45kg) in a lead melting pot and separate them. into lead particles, which not only wastes a lot of energy, consumes lead materials but also seriously pollutes the environment. In order to fundamentally solve these problems, it is necessary to adopt a new process of directly dividing lead ingots into lead cakes and lead pellets in a cold state, and its core is to manufacture lead cake granulators. Contents of the invention [0003] The object of the present invention is to provide a...
