[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0034] See also Figures 1 to 4 , the high-efficiency drop-rejection metal detection equipment may include the following contents.
[0035] Detection channel 1, the output end of detection channel 1 is connected to sorting channel 3;
[0036] A metal detection component 2 is arranged around the outside of the detection channel 1;
[0037] The sorting channel 3 includes a qualified outlet 31 coaxial with the detection channel 1, and a rejection outlet 32 arranged at the lower middle part of the sorting channel 3;
[0038] The level of the inlet of the detection channel 1 is higher than the qualified outlet 31;
[0039] A flap 33 for shielding the rejection outlet 32 is arranged inside the sorting channel 3, and a high-speed electromagnet 34 for driving the flap 33 is arranged outside the sorting channel 3;
[0040] The metal detection component 2 and the high-speed electromagnet 34 are electrically connected to the central control component 4 .
[0041] Here, when the metal detection component detects that the material passing through is an abnormal material, the flap is controlled to flip over to directly cover the qualified outlet, and the rejection outlet is opened at the same time, so that the abnormal material can fall from the rejection outlet by itself, so there is no need to locate the abnormal material, nor to carry out complicated debugging and testing, and maintenance and use are extremely convenient.
[0042] In this embodiment, the metal detection component 2 is used to detect whether the passing material contains metal substances;
[0043] Among them, materials without metal substances are qualified materials, and materials with metal substances are abnormal materials;
[0044] When the metal detection component 2 detects that the material currently passing through is abnormal material, it outputs an alarm signal to the central control component 4.
[0045] Here, the metal detection component is based on the principle of electromagnetic induction, and can detect the passage of metal materials through changes in its own current, thereby generating an alarm signal based on the current changes.
[0046] In this embodiment, when the metal detection component 2 detects that the material currently passing through is qualified material, the surface of the flap 33 and the inner wall of the detection channel 1 are in the same plane, together forming the detection channel 1. The material flows through the sorting channel 3 through the detection channel 1 and is output from the qualified outlet 31 of the sorting channel 3.
[0047] In this embodiment, the flap is normally in a fallen state, at which time it is in the same plane as the inner wall, and the top end can be slightly lower than the inner wall to prevent the material from touching the top end and bouncing when sliding past, resulting in poor material falling.
[0048] In this embodiment, the central control component 4 is used to output a rotation instruction to the high-speed electromagnet 34 when receiving an alarm signal.
[0049] In this embodiment, the high-speed electromagnet 34 is used to drive the flap 33 to flip up according to the rotation instruction, so that the end of the flap 33 touches the upper inner wall of the sorting channel 3 to block the qualified outlet 31.
[0050] In this embodiment, when the qualified outlet 31 is in a blocked state, the rejection outlet 32 is in an open state, and abnormal materials are output through the rejection outlet 32 .
[0051] Here, compared with the conventional practice of identifying abnormal materials and then rejecting them through an action mechanism, this solution directly changes the material outlet through a flap, so that as long as the flap is flipped up before the abnormal materials slide over the flap, it can be ensured that the abnormal materials can stably leave the rejection outlet.
[0052] Therefore, there is no need to carry out complicated debugging and testing of the action mechanism and the detection mechanism, which reduces the problems of rejection failure, false rejection, etc. caused by the lack of synchronization between the detection process and the action process during operation.
[0053] It is understandable that, assuming that the flow rate of the material sliding down is large, the qualified materials around the abnormal materials will inevitably be directed to the rejection outlet after the flap is turned up. Here, when the material flow rate is large, the time interval from the flap turning up to the reset can be appropriately shortened to reduce the number of qualified materials rejected.
[0054] Also, in the scheme of using an action mechanism to push abnormal materials, or using high-pressure air to blow away abnormal materials, when the material flow rate is too large, there is also a situation where the surrounding qualified materials are rejected, and the abnormal materials may not be rejected because the rejection force is dispersed. This scheme achieves rejection by changing the material channel, so there is no need to consider factors such as the force of the action mechanism and the air pressure of the high-pressure air. The rejection effect of conventional rejection equipment can be obtained regardless of the high or low material flow rate.
[0055] In this embodiment, a collecting bottle 35 is disposed below the reject outlet 32 , and the abnormal materials are output through the reject outlet 32 and fall into the collecting bottle 35 .
[0056] Here, a collecting device is provided below the reject outlet to collect abnormal materials and conduct inspection, thereby reducing the situation where metal substances are contained in the materials.
[0057] In this embodiment, the width of the flap 33 is smaller than the width of the inner wall of the inlet of the sorting channel 3;
[0058] The flap 33 is assembled through the inlet of the sorting channel 3 .
[0059] Here, the flap can be conveniently loaded or taken out through the feed port without the need for additional process holes, ensuring that the inner wall of the sorting channel is smoother and reducing damage to the material caused by bumps.
[0060] The flap is assembled on the high-speed electromagnet in the form of a latch through a sliding bearing, which makes loading and unloading easy and avoids the grease contamination problem of rolling bearings. It is suitable for food and pharmaceutical materials.
[0061] In this embodiment, the qualified outlet 31 of the sorting channel 3 adopts an easily detachable docking port to cooperate with a clamp to connect the input end of a pipeline or a packaging device.
[0062] Here, you can place containers for receiving qualified materials directly under the qualified outlet, or you can directly transport the qualified materials to the equipment of the next process through an easily detachable interface to achieve streamlined operation.
[0063] In this embodiment, the detection channel 1, the metal detection component 2, the sorting channel 3 and the central control component 4 are assembled on the rotating base 51 at the top of the bracket 5;
[0064] The rotating base 51 is used to adjust the inclination angle;
[0065] A pulley 52 is mounted on the bottom of the bracket 5 .
[0066] Here, by adjusting the inclination angle of the rotating base, the sliding speed and sliding flow rate of the material can be controlled to adapt to the physical properties of the material and the production speed.
[0067] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:
[0068] When not triggered, the flap is basically in the same plane as the inner wall of the sorting channel, and together they form the discharge channel for qualified materials. When abnormal materials pass through the metal inspection component, the flap is controlled to flip up, closing the qualified outlet and opening the rejection outlet, and it is reset after the abnormal materials fall from the rejection outlet. The flap is driven quickly and accurately by a high-speed electromagnet, and the flip-up interception action does not require special debugging, which reliably ensures that abnormal materials are rejected, and is easy to maintain and use.
