Description

Technical Field

[0001] The utility model relates to the technical field of sand core conveying, in particular to a sand core conveying device. Background Art

[0002] During the production of sand cores, the sand cores formed in the sand core box are transported to the set position through a conveyor belt and grabbed by a robot into a cargo box.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] like Figure 1 The figure shows a specific embodiment of the sand core conveying device provided by the utility model, which includes: a conveying body 10 for conveying sand cores A, the conveying body 10 includes a power wheel 11, a driven wheel (not shown in the figure) and a first conveyor belt 12 located therebetween, and the formed sand core A is placed on the first conveyor belt 12 to achieve its conveyance to a set position; it also includes a cleaning mechanism 20 for cleaning the first conveyor belt 12, the cleaning mechanism 20 includes a cleaning brush 21 located on the lower side of the first conveyor belt 12, and the cleaning brush 21 is installed on a support shaft 22, and the support shaft 22 is drivingly connected to the power wheel 11 or the driven wheel.

[0027] The above-mentioned sand core conveying device is equipped with a cleaning mechanism 20 located on the lower side of the first conveyor belt 12 to clean the first conveyor belt 12, thereby preventing the sand particles adsorbed on the sand core A from adhering to the first conveyor belt 12, resulting in the problem of excessive sand particles accumulating on the first conveyor belt 12; at the same time, since the support shaft 22 of the cleaning brush 21 is connected to the power wheel 11 or the driven wheel, it can use the power of the existing conveying body 10 to realize the rolling cleaning of the cleaning brush 21, and the cleaning effect is better.

[0028] Specifically, in one embodiment, the power wheel 11 is connected to the driving motor through the power shaft 13; the support shaft 22 and the power shaft 13 are connected by transmission through the second conveyor belt 23. That is, the cleaning brush 21 is connected by transmission to the power shaft 13 of the conveying body 10 through the support shaft 22, and the two are connected by transmission through the second conveyor belt 23, which can make the rotation direction of the cleaning brush 21 opposite to the transmission direction of the first conveyor belt 12, which is conducive to the cleaning brush 21 to clean the sand on the first conveyor belt 12, and the cleaning effect is better.

[0029] In another alternative embodiment, the power wheel 11 is connected to the driving motor through the power shaft 13; the support shaft 22 and the power shaft 13 are connected through a gear transmission group. The support shaft 22 of the cleaning brush 21 is connected to the power shaft 13 of the conveying body 10 through the gear transmission group. The gear transmission ratio can be designed according to the situation so that the cleaning brush 21 rotates at a more reasonable speed to obtain a better cleaning effect.

[0030] Specifically, Figure 2 As shown, the cleaning brush 21 includes a brush cylinder 211 sleeved on the support shaft 22 and bristles 212 arranged on the brush cylinder 211. The brush cylinder 211 is fixedly connected to the support shaft 22, so that the cleaning brush 21 and the first transmission belt can be conveyed in opposite directions. More specifically, the cleaning brush 21 uses polytetrafluoroethylene bristles 212, which have the advantages of chemical corrosion resistance and low friction coefficient, thereby improving the cleaning effect of the first conveyor belt 12.

[0031] Specifically, in an optional embodiment, the cleaning brush 21 extends along the width direction of the first conveyor belt 12 , and the length of the cleaning brush 21 is greater than the width of the first conveyor belt 12 .

[0032] Specifically, the sand core conveying device further includes a sand collecting device 30, such as Figure 1As shown, the sand grain collecting device 30 includes a collecting funnel 31 located below the cleaning mechanism 20 and a collecting vehicle 32 located below the collecting funnel 31. The sand grains swept off by the cleaning mechanism 20 fall into the collecting vehicle 32 through the collecting funnel 31, realizing the transfer of waste sand. More specifically, the width of the collecting funnel 31 is greater than the width of the first conveyor belt 12, so that the sand grains on the first conveyor belt 12 can completely fall into the collecting funnel 31.

[0033] Specifically, in an alternative embodiment, as Figure 1 shown, the above sand core conveying device further includes an image acquisition device 40 located above the conveying main body 10. The acquisition surface of the image acquisition device 40 faces the upper surface of the first conveyor belt 12 to acquire the position of the sand core A on the first conveyor belt 12 when the conveying main body 10 is running, facilitating the precise grasping of the sand core A by the manipulator B.

[0034] Specifically, in order to further improve the sand grain cleaning effect, in an alternative embodiment, as Figure 3 shown, the sand core conveying device further includes a jet cleaning mechanism 50 located below the first conveyor belt 12. The jet cleaning mechanism 50 includes a support frame 51 extending along the width direction of the first conveyor belt 12 and an air supply pipe 52 arranged on the support frame 51. The air supply pipe 52 is used to supply high-pressure air. A plurality of air jet holes 53 are provided on the air supply pipe 52. The air jet holes 53 face the lower surface of the first conveyor belt 12 and are used to perform jet treatment on the first conveyor belt 12 after being cleaned by the cleaning mechanism 20 to clean the sand grains attached to the first conveyor belt 12.

[0035] Specifically, in an alternative embodiment, the jet cleaning mechanism 50 is located within the coverage area of the sand grain collecting device 30, that is, the jet cleaning mechanism 50 is located within the coverage area of the collecting funnel 31 of the sand grain collecting device 30, so that the sand grains cleaned by the jet cleaning mechanism 50 fall into the collecting funnel 31. At the same time, the jet cleaning mechanism 50 is located on the side far from the cleaning mechanism 20 to prevent the sand grains swept by the cleaning mechanism 20 from being blown away when the jet cleaning mechanism 50 jets air.

[0036] Obviously, the above embodiments are merely examples for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. The obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
