Problems solved by technology

[0002] The existing rollers are generally driven by belt wheels, which tend to slip after a long time or when the roller is sprayed with water, and the running speed drops significantly.
In addition, the existing drum uses external water spraying to cool down the sand temperature, but if the customer's output is large and the sand temperature is high, the existing cooling method cannot make the pouring reach the required temperature, resulting in burns on the white mold and failure to work normally.

Embodiment 1

[0023] see figure 1 , in the figure, the needle wheel cooling machine with automatic sand temperature control of the present invention includes a drum 1, a drum cover 2 and a drum driving device 6, retaining wheels 3 are provided at the edges of both ends of the drum, and sand inlets are respectively provided at both ends of the drum. The mouth 4 and the sand outlet 5 are provided with a spray device 7 between the outside of the drum and the drum outer cover, and an automatic atomization cooling device 8 arranged inside the drum, and a fan interface 9 is provided at one end of the drum sand outlet.

[0024] see Figure 2-4 , the drum driving device includes a transmission mechanism and a power mechanism, wherein the transmission mechanism includes a pair of pin chain rings 6-1 and a double-row sprocket 6-2 for meshing transmission, and the two sides of the rotating shaft of the double-row sprocket are rotatably supported on bearings And on the bearing seat 6-3.

[0025] see ...

Embodiment 2

[0034] see figure 2 , the structure of this embodiment is similar to that of Embodiment 1, and the same numbers represent the same meanings, which will not be repeated here. The difference is that the power mechanism described in this embodiment includes a motor 6-4 and a speed reducer 6-5 ; One end of the rotating shaft of the double-row sprocket is directly connected with the reducer through the coupling 6-6.

Embodiment 3

[0036] see Figure 8 , the structure of this embodiment is similar to that of Embodiment 1, and the parts with the same numbers represent the same meaning, so they will not be repeated here. The pipe 7-1 is provided with at least one row of spray holes 7-2 along the surface of the spray pipe towards the side of the drum.

Abstract

The invention discloses a pinwheel cooling machine capable of automatically controlling sand temperature, which comprises a roller, a roller casing and a roller driving device, retainer wheels are arranged at the edge of two ends of the roller, a sand inlet and a sand outlet are respectively arranged at two ends of the roller, a spray apparatus is arranged between the external part of the roller and the roller casing, the cooling machine also comprises an automatic atomization cooling device arranged in the roller, a blower fan interface is arranged at one end of the sand outlet of the roller, the automatic atomization cooling device comprises an atomization pipeline, the roller driving device comprises a transmission mechanism and a power mechanism, the transmission mechanism contains a pair of pin chain rings and double strand chain wheels which enable engagement and transmission, and two sides of a rotating shaft of the double strand chain wheel are supported on a bearing and a bearing pedestal in a rotation manner. The pinwheel cooling machine has the advantages that the transmission is reliable and stable, appearance of skid phenomenon can be avoided, temperature at the sand outlet can be effectively controlled, and the sand treatment amount in the machine in unit time is increased.

Description

technical field [0001] The invention belongs to the technical field of the lost foam casting industry, and in particular relates to a pin wheel cooler with automatic sand temperature control. Background technique [0002] Existing drums are generally driven by belt pulleys, which tend to slip over time or when the drum is sprayed with water, and the running speed drops obviously. In addition, the existing drum uses external water spraying to cool down the sand temperature, but if the customer's output is large and the sand temperature is high, the existing cooling method cannot make the pouring reach the required temperature, resulting in burns on the white mold and failure to work normally. Production. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a reliable and stable transmission, avoid slippage, and effectively control the temperature of the s...
