Description
Technical Field
[0001] This utility model relates to the field of resin sand production technology, specifically to a resin sand production line conveying device with a nested screening structure. Background Technology
[0002] Resin sand is a synthetic binder. It refers to molding sand or core sand that uses synthetic resin as the binder for sand particles. After molding or coreing with resin sand, the resin undergoes an irreversible cross-linking reaction and solidifies through the action of a curing agent, thus giving the mold or core the necessary strength. Resin sand is widely used as molding sand in modern casting production. Molding sand with resin as a binder mainly includes hot-film coated resin sand, hot-box resin sand, cold-box resin sand, furan resin sand, and I-furan resin self-hardening sand. Resin sand has high strength after hardening, making it particularly suitable for machine molding and capable of producing complex, thin-walled castings. Generally, the agglomerated resin sand is first broken up before it is used. However, existing resin sand production line conveying devices can only transport resin sand and cannot screen it, making it inconvenient to use and hindering its subsequent reuse.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see Figure 1-6This utility model provides a technical solution: a resin sand production line conveying device with a nested screening structure, including a base 10, a screening box 20, a filter screen 201, a connecting plate 202, a conveyor belt 203, a guide plate 204, a motor 301, a rotating shaft 302, a cleaning rod 303, a discharge port 304, a receiving groove 305, a guide plate 306, and a diversion groove 307;
[0032] The conveying device of this resin sand production line can divert resin sand. The specific implementation method is as follows:
[0033] A sieving box 20 is mounted on the surface of the base 10. The surface of the base 10 is equipped with a diversion and transport mechanism, which includes: symmetrically mounted connecting plates 202 on the surface of the base 10, with a conveyor belt 203 positioned between the connecting plates 202; multiple layers of filter screens 201 installed inside the sieving box 20; a guide plate 204 fixedly connected to the inner wall of the sieving box 20; the multiple layers of filter screens 201 have different mesh spacings; the bottom of the cleaning rod 303 is in contact with the surface of the filter screen 201, and the end of one cleaning rod 303 is in contact with the bottom surface of the inner wall of the sieving box 20; the guide plate 204 is a spiral structure plane, and the bottom of the guide plate 204 is positioned corresponding to the position of the filter screen 201.
[0034] Resin sand can be placed inside the screening box 20. At this time, the resin sand falls on the surface of the guide plate 204, causing the resin sand to move downward along the surface of the guide plate 204. Then, the resin sand falls on the surface of the upper filter screen 201 along the guide plate 204. At this time, the filter screen 201 can filter the resin sand. The resin sand with a larger diameter remains on the surface of the filter screen 201, while the resin sand with a smaller diameter falls through the mesh of the filter screen 201 and falls on the surface of the bottom filter screen 201. The resin sand can be filtered multiple times through multiple layers of filter screens 201. At this time, the resin sand on the surface of the filter screen 201 falls onto the surface of different conveyor belts 203 through the receiving groove 305 and the guide plate 306. The transmission mechanism drives the conveyor belts 203 to move, and the conveyor belts 203 transport the resin sand on the surface.
[0035] The conveying device of this resin sand production line improves the filtration efficiency of filter screen 201. The specific implementation method is as follows:
[0036] The screening box 20 is equipped with a rotating mechanism, which includes: a motor 301 mounted on the surface of the base 10, a rotating shaft 302 fixedly connected to the end of the output shaft of the motor 301, the other side of the rotating shaft 302 inserted into the interior of the screening box 20, and multiple cleaning rods 303 mounted on the surface of the rotating shaft 302; a feed inlet 304 embedded in the surface of the filter screen 201, and a receiving groove 305 fixedly connected to the bottom of the filter screen 201; and multiple guide rods fixedly connected to the surface of the screening box 20. The guide plate 306 and the inner bottom surface of the screening box 20 are embedded with a flow channel 307. The surface of the screening box 20 is provided with multiple openings, and the openings of the screening box 20 are connected to the end of the receiving groove 305. The guide plates 306 are respectively set inside the openings of the screening box 20. The guide plates 306 are set as inclined mechanisms, and the end of the guide plates 306 is in contact with the surface of the conveyor belt 203. The flow channel 307 is set as an inclined channel, and the end of the flow channel 307 is set corresponding to the position of the opening of the screening box 20.
[0037] When the resin sand is placed inside the screening box 20, the motor 301 can be started. The motor 301 drives the rotating shaft 302 to rotate, and the rotating shaft 302 drives the cleaning rod 303 to rotate. The cleaning rod 303 rotates on the bottom surface of the filter screen 201 and the inner wall of the screening box 20, which can flatten the resin sand on the surface of the filter screen 201 and speed up the filtration of the resin sand. At the same time, the cleaning rod 303 moves the larger diameter resin sand on the surface of the filter screen 201. When it moves to the discharge port 304, the larger diameter resin sand on the surface of the filter screen 201 can fall into the receiving tank 305. At this time, the receiving tank 305 can perform secondary filtration of the resin sand. The resin sand moves on the surface of the receiving tank 305, causing it to move to the surface of the guide plate 306. The resin sand then moves along the guide plate 306 to the surface of the conveyor belt 203, where it can be discharged. At the same time, when the cleaning rod 303 rotates on the bottom surface of the inner wall of the screening box 20, it can push the resin sand on the bottom surface of the screening box 20 to move into the interior of the diversion trough 307, causing it to move along the diversion trough 307 to the guide plate 306, and then fall onto the surface of the conveyor belt 203 of that layer through the guide plate 306.
[0038] Working principle: When using the resin sand production line conveying device with a nested screening structure, a screening box 20, a filter screen 201, a connecting plate 202, a conveyor belt 203, and a guide plate 204 are set up to divert the resin sand. A receiving trough 305, a guide plate 306, and a diversion trough 307 are set up to improve the filtration efficiency of the filter screen 201 and increase the overall practicality.
[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
