Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of zinc ingot processing, in particular to zinc ingot rolling equipment. Background Art
[0002] Zinc has active chemical properties, and has quite good corrosion resistance, mechanical properties and good formability. In metal consumption, zinc ranks fifth after steel, aluminum, copper and manganese. The consumption areas of zinc are galvanizing, brass and bronze, zinc-based alloys and chemical products, and zinc plates are mainly used in the construction industry and light industry. During production, zinc is generally melted and poured into a mold to form a zinc ingot, which is convenient for transportation as a raw material. Zinc plate rolling molding is generally processed with zinc ingots as raw materials. Due to the large thickness of zinc ingots, they are prone to cracking, folding and sticking to the rollers during rolling, so they are not suitable for direct rolling processing. In view of the above situation, the utility model provides a zinc ingot rolling equipment. Utility Model Content
[0003] The utility model aims to provide a zinc ingot rolling equipment.
[0004] The above technical objectives of the utility model are achieved through the following technical solutions:
[0005] A zinc ingot rolling equipment comprises an equipment outer frame, a feed port, a feed conveying roller, a feed roller, a discharging roller, a discharging port, a discharging conveying roller and a rolling mechanism, wherein the feed conveying roller is installed at the bottom of the feed port, the discharging conveying roller is installed at the bottom of the discharging port, the rolling mechanism is installed on the equipment outer frame, between the feed port and the discharging port, the rolling mechanism comprises a pair of feed rollers and a pair of discharging rollers, the pair of feed rollers consists of an upper feed roller and a lower feed roller, the shaft ends of the upper feed roller and the lower feed roller are connected by a gear pair, and the upper feed roller and the lower feed roller are provided with concave arc grooves; a pair of discharging rollers consists of an upper discharging roller and a lower discharging roller, the shaft ends of the upper discharging roller and the lower discharging roller are connected by a gear pair, and trimming knives are provided on both sides of the discharging roller.
[0006] Furthermore, a heat preservation resistance wire is provided above the rolling mechanism, and a waste collection tank is provided below the rolling mechanism. The heat preservation resistance wire can keep the zinc ingot warm during the rolling process to avoid excessive cooling and affecting the rolling process. The waste collection tank is used to collect waste chips generated during the rolling process.
[0007] Furthermore, a preheating resistance wire is provided on the equipment outer frame between the feed port and the rolling mechanism and above the feed conveying roller. The preheating resistance wire heats the rolled zinc ingot to improve the plasticity of the zinc ingot and avoid defects such as cracks.
[0008] Further, at least a pair of intermediate rollers are installed between the feeding roller and the discharging roller. The intermediate rollers play a transitional role, gradually rolling the zinc ingot thinner.
[0009] Further, the arc-shaped grooves on the upper feeding roller and the lower feeding roller are arranged in a dislocation manner. The arc-shaped grooves can increase the deformation amount of the zinc ingot during the initial pressing, making it better formed and processed.
[0010] Further, the cross-section of the trimming knife is in a right-angled triangle structure. The right-angled sides of the trimming knives on the upper discharging roller and the lower discharging roller are arranged in a fitting manner. The trimming knife can cut the defective positions on both sides of the rolled plate, reducing the subsequent processing procedures.
[0011] In summary, the present utility model has the following beneficial effects: By setting the heat preservation resistance wire and the preheating resistance wire, the present utility model can perform corresponding heat treatment on the zinc ingot rolling process, avoiding the generation of rolling defects.

The feeding roller 5 is composed of an upper feeding roller 5a and a lower feeding roller 5b, and the shaft ends of the upper feeding roller 5a and the lower feeding roller 5b are connected by a gear pair 12, and the upper feeding roller 5a and the lower feeding roller 5b are provided with a concave arc groove 13; a pair of discharging rollers 7 is composed of an upper discharging roller 7a and a lower discharging roller 7b, and the shaft ends of the upper discharging roller 7a and the lower discharging roller 7b are connected by a gear pair 14, and trimming knives 15 are provided on both sides of the discharging roller 7.
[0018] Furthermore, a heat preservation resistance wire 8 is provided above the rolling mechanism, and a waste collection tank 9 is provided below the rolling mechanism. The heat preservation resistance wire 8 can keep the zinc ingot warm during the rolling process to avoid excessive cooling and affecting the rolling process. The waste collection tank 9 is used to collect waste chips generated during the rolling process.
[0019] Furthermore, a preheating resistance wire 4 is provided on the equipment outer frame 1 between the feed port 2 and the rolling mechanism and above the feed conveying roller 3. The preheating resistance wire 4 heats the rolled zinc ingot to improve the plasticity of the zinc ingot and avoid defects such as cracks.
[0020] Furthermore, at least one pair of intermediate rollers 6 is installed between the feed roller 5 and the discharge roller 7. The intermediate rollers 6 play a transition role so that the zinc ingot is gradually rolled and thinned.
[0021] Furthermore, the arc grooves 13 on the upper feed roller 5a and the lower feed roller 5b are staggered, and the arc grooves 13 can increase the deformation of the zinc ingot during the initial pressing, so that it can be better formed and processed.

[0023] Working principle: The zinc ingots to be processed are heated to a certain temperature by a heating device, and then clamped and placed on the feeding conveying rollers 3 at the feeding port 2 by tools such as a manipulator. While the feeding conveying rollers 3 convey the feed, the preheating resistance wire 4 is electrified for further heating to make it reach or maintain the rolling temperature. The zinc ingots enter the rolling mechanism from the feeding port 2 and are initially rolled into shape by the feeding rolling rollers 5, and then are rolled one or more times by the intermediate rolling rollers 6 to gradually make the zinc ingots thinner into zinc plates. Then, after being trimmed by the discharging rolling rollers 7, they are conveyed out by the discharging conveying rollers 11. During the rolling process, the zinc material is insulated by the heat preservation resistance wire 8 to keep it in a better rolling temperature range. The waste chips generated during rolling are collected and processed through the waste collection tank 9.
