The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The invention is explained in detail below with reference to the figures and with reference to exemplary embodiments:

as shown in fig. 1 to 3, an air-jet removing structure of a metal detector comprises a conveyor belt 1, wherein an air flow nozzle 2 lower than the surface of the conveyor belt 1 is arranged at the tail of the conveyor belt 1, the air flow nozzle 2 is positioned at one side of the conveyor belt 1, the opening of the air flow nozzle faces the other side, and the air flow nozzle 2 is used for removing substandard products in the downward throwing process.

In this embodiment, because the afterbody of conveyer belt 1 sets up airflow nozzle 2, and airflow nozzle 2 is located one side of conveyer belt 1 and its opening is towards the opposite side simultaneously, consequently, when the detection machine detects substandard product, and after substandard product is thrown from conveyer belt 1 afterbody, airflow nozzle 2 carries out the air current to substandard product in the air and sprays, thereby blow out substandard product the scope of the falling point of substandard product, thereby realize rejecting substandard product in the product, because the primary structure who rejects is airflow nozzle 2, consequently, can avoid the situation that the unloading board 3 bullet that is overturned when substandard product is rejected among the prior art flies or throws and flies, can improve subsequent sorting efficiency.

In this embodiment, because the setting of airflow nozzle 2 is at 1 afterbody in the transportation area, and when airflow nozzle 2 rejected not up to standard product, not up to standard product is being in aloft, consequently, can avoid 2 spun air currents of airflow nozzle to cause the influence to other products, influence the falling point scope of up to standard product, when avoiding waiting to examine the product on the transportation area 1 and comparatively avoiding, reject the new problem that the rejection action of not up to standard product influences adjacent product.

Specifically, the tail of the conveying belt 1 is further provided with an inclined blanking plate 3, the top of the blanking plate 3 is lower than the height of the conveying belt 1, and the airflow spray head 2 is arranged on the blanking plate 3. Through setting up down flitch 3, can pass through for the product that 1 afterbody of conveyer belt was thrown down, avoid the initial velocity on the conveyer belt 1 to cross when low excessively, the product up to standard can't be transported to the product up to standard conveyer belt 1 on.

Specifically, a supporting rod perpendicular to the blanking plate 3 is arranged on the end face of the blanking plate 3, and the airflow nozzle 2 is fixed on the blanking plate 3 through the supporting rod. In this embodiment, as shown in fig. 1, the number of the support rods is two, the two support rods are fixed on the end surface of the blanking plate 3 through bolts, the two support rods are made of aluminum alloy rods, and the airflow nozzle 2 and the support rods are fixed by welding or inserting.

Specifically, the airflow nozzles 2 are flat nozzles or multi-head side-by-side nozzles; the flat spray heads or the multi-head side-by-side spray heads are arranged in parallel to the blanking plate 3. The air flow spray head 2 is a flat spray head or a multi-head side-by-side spray head, so that air flow sprayed by the air flow spray head 2 is flat, the stress area of the product can be enlarged when the product is blown, and the stability of the product when the product is removed is improved.

Specifically, the airflow nozzles 2 are multi-head side-by-side nozzles, the multi-head side-by-side nozzles include a plurality of nozzles with openings arranged in a line, and the number of the nozzles of the multi-head side-by-side nozzles is at least three. The multi-head side-by-side type sprayer comprises a hollow buffer body, as shown in fig. 1 and 3, the buffer body is a cuboid, the multi-head side-by-side type sprayer further comprises a sprayer, the sprayer is communicated with a cavity of the buffer body, the cavity of the buffer body is further communicated with a flexible hose 5, as shown in fig. 3, and the flexible hose 5 is communicated with three sprayers through the cavity of the buffer body.

Specifically, the range of the inclination amplitude of the blanking plate 3 is as follows: 30 to 60. In this embodiment, the inclination of the blanking plate 3 is 45 °.

Specifically, still be equipped with two deflector 31 that are the splayed setting on the flitch 3 down, two deflector 31 are followed the transportation direction symmetry of transportation area 1 sets up, and the interval of the higher one side in two deflector 31 positions is greater than the interval of opposite side. In this embodiment, through setting up deflector 31, can be so that the product up to standard that drops on lower flitch 3 passes through accurate landing of deflector 31 to product transport belt up to standard 1, carries out subsequent encapsulation process again.

Specifically, the air flow sprayer further comprises a fan 4, and the air inlet end of the air flow sprayer 2 is communicated with the air outlet end of the fan 4 through a flexible hose 5. Fan 4 in this embodiment is high pressure positive blower 4, and high pressure positive blower 4 spun high-speed high pressure draught can effectively improve the effect of rejecting of substandard product.

Optionally, the tail of the conveyer belt 1 is provided with a waste collecting box 6 for collecting products which do not reach the standard, and the opening of the waste collecting box 6 is opposite to the opening of the airflow nozzle 2 and is arranged on two sides of the tail of the conveyer belt 1. Set up waste product collection box 6 and be favorable to the collection of not up to standard product, can be so that not up to standard product can be directly blown in waste product collection box 6 through air current shower nozzle 2 in, improve the collection efficiency of follow-up not up to standard product.

Preferably, the waste collecting box 6 is further provided with a plurality of air leakage holes 61, and the air leakage holes 61 are located on the other side of the opening of the waste collecting box 6. Through setting up hourglass wind hole 61, can be so that blow the partial air current of substandard product and can discharge through hourglass wind hole 61, with the backward flow influence of 2 blowout air currents of low air shower nozzle, avoid it to influence the throwing point of follow-up substandard product, in this embodiment, like fig. 1, hourglass wind hole 61 is the bar hole of vertical setting, and a plurality of bar holes are rectangle array setting.

The working principle and the working process of the embodiment are as follows:

when the method is used, a product to be detected is placed at the head of the conveyor belt 1, then the metal detector is started to detect the product on the conveyor belt 1, the product which does not reach the standard is detected by the metal detector, and after the product which does not reach the standard is thrown down from the tail of the conveyor belt 1, the fan 4 is started, so that the airflow sprayer 2 performs airflow jet on the product which does not reach the standard, the product which does not reach the standard in the air is blown into the waste product collecting box 6, and the rejection action of the product which does not reach the standard is completed. Because the main structure of rejecting is air current shower nozzle 2, consequently, can avoid being thrown the condition that flies or throws by unloading board 3 that overturns when not up to standard product rejects among the prior art. Simultaneously, because when substandard product was rejected to this embodiment, substandard product was in the air, consequently, can avoid 2 spun air currents of air current shower nozzle to cause the influence to other products, influences the falling point scope of substandard product.

It is to be understood that the above embodiments are merely exemplary embodiments that have been employed to illustrate the principles of the present invention, and that the present invention is not limited thereto.
