Description

Technical Field

[0002] Coconut flakes refer to a kind of food that is made by drying the coconut flesh and grinding it into shreds or powder. It is very popular in Guangdong, Hainan and Fujian in China, and is used to make various desserts, cakes, dishes, etc.

[0003] Metal detection of coconut flakes determines whether it can meet the requirements of everyone's health. If there is metal in coconut flakes, it will pose a great threat to the safety of consumers. When the existing metal detection device for coconut flakes processing detects coconut flakes with metal foreign matter, it pushes the coconut flakes through a pushing mechanism to make the coconut flakes and metal impurities fall toward the magnetic rod. The speed of the coconut flakes and metal impurities falling vertically is fast and the impact force is large. It is difficult for the metal impurities to be stably adsorbed on the magnetic rod, so that the magnetic rod adsorbs less metal impurities, resulting in poor separation effect of coconut flakes and metal impurities.

[0026] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0028] See also Figures 1 to 12The present application proposes a metal detection device for processing coconut flakes, comprising a conveyor belt 1, a metal detector 2, a material receiving mechanism 4, a driving mechanism 3 and a material dividing mechanism 5; the metal detector 2 is connected to the conveyor belt 1 to detect the coconut flakes on the conveyor belt 1; the material receiving mechanism 4 is arranged below the conveyor belt 1, and comprises a fixed seat 43, a material receiving box 42 and a rotating column 421, the fixed seat 43 is provided with a mounting plate 431, one end of the rotating column 421 is fixedly connected to the material receiving box 42, and the other end is rotatably connected to the mounting plate 431, and the rotating column 421 is provided with a mounting plate 431. The rotating column 421 is sleeved with a torsion spring 4211, and the two ends of the torsion spring 4211 are respectively connected to the material receiving box 42 and the mounting plate 431, and an electromagnet 424 is arranged inside the material receiving box 42; the driving mechanism 3 is electrically connected to the metal detector 2, so as to move the coconut flakes detected to contain metal impurities to the material receiving mechanism 4; the material separating mechanism 5 is arranged under the material receiving box 42, so as to receive the coconut flakes when the electromagnet 424 is energized, and receive the metal impurities when the electromagnet 424 is de-energized, and separate the coconut flakes from the metal impurities.

[0029] In the embodiments provided in this application, please refer to Figure 1 and Figure 2When the powdered coconut flakes are transported to the bottom of the metal detector 2 on the conveyor belt 1, if metal impurities are detected in the coconut flakes, the driving mechanism 3 will be activated and the pile of coconut flakes will enter the receiving mechanism 4. The metal impurities may include impurities such as iron filings that can be attracted by magnets. The top and side walls of the receiving box 42 are respectively provided with a receiving port and a dropping port. When the coconut flakes and metal impurities fall from the receiving port onto the electromagnet 424 in the receiving box 42, as the amount of coconut flakes increases, the receiving box 42 slowly tilts. When the receiving box 42 tilts slightly, the tilt angle is small, and the powdered coconut flakes will first slide from the dropping port to the dividing mechanism 5 below. When the powdered coconut flakes slide in the receiving box 42, the pressure on the docking box 42 is small, and the iron filings will stably stay and be adsorbed in the horizontal or approximately horizontal receiving box 42 to prevent the iron filings from rolling too much relative to the electromagnet 424 after falling. As piles of powdered coconut flakes fall into the receiving box 42, the iron filings in the receiving box 42 will increase. The receiving box 42 resists the elastic force of the torsion spring 4211 and tilts downward. When the number of iron filings is sufficient, the electromagnet 424 will lose power and lose magnetism. The iron filings will slide from the material drop opening of the receiving box 42 to the material distribution mechanism 5; wherein, a weight sensor electrically connected to the electromagnet 424 can be provided in the receiving box 42. When the number of iron filings in the receiving box 42 increases, its overall weight becomes larger. The weight sensor can transmit the weight signal to the controller, and the controller will cause the electromagnet 424 to lose power. Of course, when the number of iron filings increases, the receiving box 42 will tilt. An encoder can also be provided on the receiving box 42. When the receiving box 42 tilts to a predetermined angle, the encoder can transmit the angle signal to the controller, and the controller will cause the electromagnet 424 to lose power. When metal impurities such as iron filings fall into the material distribution mechanism 5, the receiving box 42 returns to a horizontal position under the action of the torsion spring 4211, and the electromagnet 424 will restore its magnetism. The coconut flakes and metal impurities that fall into the material dividing mechanism 5 successively will be separated and fall to different positions.

[0030] The coconut flakes and metal impurities falling from the conveyor belt 1 will exert a certain impact force on the electromagnet 424 in the receiving box 42, which may damage the electromagnet 424. In order to prevent the receiving box 42 from tilting too much after being impacted and to prevent the electromagnet 424 from being damaged, in some embodiments of the present application, please refer to Figure 2 The receiving mechanism 4 also includes a material drop bin 41, which is connected to the conveyor belt 1 and is located above the receiving box 42. A plurality of inclined buffer plates 411 are arranged in the material drop bin 41, and the inclination angles of the plurality of buffer plates 411 from top to bottom in the material drop bin 41 decrease in sequence. When the coconut flakes and metal impurities fall from the uppermost buffer plate with a larger inclination angle to the lowermost buffer plate 411 with a smaller inclination angle, and then fall from the lowermost buffer plate 411, the impact force on the lower electromagnet 424 will be reduced.

[0031] In some embodiments of this application, please refer to Figure 2 and Figure 5The material distribution mechanism 5 includes a mounting seat 51, a material distribution platform 52, a first material receiving box, a second material receiving box and a blocking mechanism. A first button 511 is provided on the top of the mounting seat 51, and the first button 511 is electrically connected to the electromagnet 424; the material distribution platform 52 is inclined and connected to the mounting seat 51, and the material distribution platform 52 has a first material drop channel 521 and a second material drop channel that are interconnected. The first material drop channel 521 is located below the material receiving box 42, and a separator is provided in the middle of the second material drop channel, which divides the second material drop channel into the first material distribution channel 522 and the second material drop channel. The material distribution channel 523, the extension direction of the first material distribution channel 522 coincides with the extension direction of the first material dropping channel 521; the first material receiving box is located below the material distribution platform 52 and corresponds to the first material distribution channel 522; the second material receiving box is located below the material distribution platform 52 and corresponds to the second material distribution channel 523; the blocking mechanism is provided on the material distribution platform 52, for closing and opening the first material distribution channel 522, so that the coconut flakes can enter one of the first material receiving box and the second material receiving box, and metal impurities can enter the other of the first material receiving box and the second material receiving box.

[0032] The shredded coconut will first fall into the first material distribution channel 521, and when the blocking mechanism opens the first material distribution channel 522, the shredded coconut will pass through the first material distribution channel 522 and fall into the first material receiving box; when the blocking mechanism closes the first material distribution channel 522, the shredded coconut will be guided by the blocking mechanism to the second material distribution channel 523 and slide into the second material receiving box; when the receiving box 42 is tilted to press the first button 511, the electromagnet 424 will lose power and magnetism, and the metal impurities will slide into the first material distribution channel 521, and the blocking mechanism will move from opening the first material distribution channel 522 to closing the first material distribution channel 522, so that the metal impurities pass through the second material distribution channel 523 and slide into the second material receiving box, so that the metal impurities and the shredded coconut fall to different positions, and the shredded coconut and the metal impurities are successfully separated. After the receiving box 42 presses the first button 511, the blocking mechanism will also move from closing the first distributing channel 522 to opening the first distributing channel 522, so that the metal impurities pass through the first distributing channel 522 and slide into the first receiving box, and the metal impurities and the coconut flakes can also fall to different positions. Among them, the first button 511 can be a reset button. When the receiving box 42 rotates upward under the action of the torsion spring 4211, the first button 511 returns to its original position, the circuit where the electromagnet 424 is located will be closed again, and the electromagnet 424 will be energized to restore its magnetism.

[0033] For further information, see Figure 7 The blocking mechanism includes a redirecting plate 53, a driving motor 5221 and a button switch. The redirecting plate 53 is arranged on the material distribution platform 52. The driving motor 5221 is installed on the material distribution platform 52 and connected to the redirecting plate 53, and can rotate the redirecting plate 53 to abut against the partition body to close the first material distribution channel 522; the button switch is arranged on the top of the mounting seat 51 and is electrically connected to the driving motor 5221.

[0034] When the material receiving box 42 presses the first button 511 and the button switch, the driving motor 5221 starts and causes the redirecting plate 53 to rotate a certain angle and to be close to the separator, thereby closing the first material distribution channel 522, and the redirecting plate 53 will guide the metal impurities to the second material distribution channel 523. When the material receiving box 42 releases the first button 511 and the button switch, the driving motor 5221 reverses and causes the redirecting plate 53 to return to the initial position of opening the first material distribution channel 522. The driving motor 5221 may be a servo motor.

[0035] Understandably, see Figure 5 The blocking mechanism may also include a redirecting plate 53 and a first elastic member 531. The redirecting plate 53 is rotatably mounted on the upper surface of the material distribution platform 52. Both ends of the first elastic member 531 are respectively connected to the redirecting plate 53 and the material distribution platform 52, so that the redirecting plate 53 can abut against the partition to close the first material distribution channel 522.

[0036] During the falling of the coconut flakes, since the powdered coconut flakes are light and in a flowing state, the impact force of the coconut flakes on the redirecting plate 53 is small and cannot overcome the elastic force of the first elastic member 531. The coconut flakes will be guided to the second material distribution channel 523 and fall into the second material receiving box. Subsequently, during the falling of the metal impurities, since the metal impurities are heavy, the impact force on the redirecting plate 53 is large and greater than the elastic force of the first elastic member 531. The metal impurities will push the redirecting plate 53 away and rotate the redirecting plate 53 to open the first material distribution channel 522. The metal impurities will fall from the first material distribution channel 522 into the first material receiving box.

[0037] See also Figure 5 and Figure 6 Since the metal impurities are constantly flowing when impacting the redirecting plate 53, as the metal impurities continuously enter the first distribution channel 522, the impact force of the remaining metal impurities will become smaller, and a small amount of metal impurities will be guided by the redirecting plate 53 to the first blanking channel 521. In order to prevent a small amount of metal impurities and coconut flakes from falling into the same position and being unable to be separated, a magnetic plate 5231 can be obliquely installed at a position of the second distribution channel 523 away from the first blanking channel 521. The coconut flakes will be guided away by the magnetic plate 5231, and a small amount of metal impurities will be adsorbed by the magnetic plate 5231, thereby preventing the small amount of metal impurities and coconut flakes from mixing.

[0038] Since the metal detector 2 will detect multiple piles of coconut flakes with metal impurities, the magnetic plate 5231 will absorb the metal impurities entering the second material distribution channel 523 for multiple times. The volume of the magnetic plate 5231 is fixed and cannot absorb more metal impurities. In order to adapt to the multiple adsorption of metal impurities and make the metal impurities leave the second material distribution channel 523 and be separated from the coconut flakes, in some embodiments of the present application, the second material receiving box has a first accommodating chamber and a second accommodating chamber, and the first accommodating chamber is correspondingly located below the guide plate 55; the separator is away from the first drop A receiving groove is provided at one end of the channel 521, and a first motor 541 is provided in the receiving groove. The first motor 541 is connected to a magnetic column 5411 located in the second material distribution channel 523. A guide plate 5232 close to the second material receiving box is provided in the second material distribution channel 523. The guide plate 5232 is inclined to guide the coconut flakes to the second receiving chamber. An inclined guide plate 55 is fixedly connected to the top of the guide plate 5232. The guide plate 55 has a scraping end close to the magnetic column 5411, and the magnetic column 5411 is at least partially located above the scraping end.

[0039] The bottom of the magnetic column 5411 can be spaced a small distance from the surface of the second material distribution channel 523. When the metal impurities slide close to the magnetic column 5411 or touch the magnetic column 5411, they will be adsorbed by the magnetic column 5411, the first motor 541 is in the starting state, and the magnetic column 5411 continuously rotates around its own axis. When the metal impurities on the outer surface of the magnetic column 5411 increase, the outer metal impurities will touch the scraping end of the guide plate 55 tilted downward. As the magnetic column 5411 rotates, the outer metal impurities will be scraped off to the upper surface of the guide plate 55, and the metal impurities will slide along the guide plate 55 to the first accommodating chamber below. The coconut flakes will be guided to the second accommodating chamber by the guide plate 5232, so that the coconut flakes and the metal impurities can be further separated.

[0040] In some embodiments of this application, please refer to Figure 2 and Figure 3 A fixed box 44 is provided on the side wall of the material receiving box 42, and an elastic baffle 441 is provided on the inner bottom wall of one end of the fixed box 44 close to the rotating shaft. A circulation shell 45 is connected to the bottom of the fixed box 44. The circulation shell 45 has an inclined channel, an arc-shaped channel and a vertical channel that are interconnected. The end of the fixed box 44 away from the rotating column 421 is connected to the inclined channel, a first counterweight ball is provided in the arc-shaped channel and a rotating rod is rotatably installed, three fan-shaped shift plates 451 are provided at intervals on the outer peripheral wall of the rotating rod, a plurality of second counterweight balls are provided in the vertical channel, and a third counterweight ball 442 abutting the elastic baffle 441 and the second counterweight ball is provided in the fixed box 44.

[0041] When the receiving box 42 is tilted to about thirty degrees, the third counterweight ball 442 in the fixed box 44 bends the elastic baffle 441 against it and quickly rolls to the end of the fixed box 44 away from the rotating column 421, which can press the first button 511 more forcefully, and also make the receiving box 42 overcome the elastic force of the torsion spring 4211 and quickly tilt downward to press the first button 511, thereby reducing the time that the receiving box 42 is in a state of large inclination and increasing the time that the receiving box 42 maintains a small inclination, further preventing metal impurities from falling on the electromagnet 424 in the receiving box 42 from having too large an activity range, so as to more stably absorb more metal impurities and improve the absorption effect of fallen metal impurities. When the metal impurities slide down, the material receiving box 42 rotates upward, the third counterweight ball 442 rolls from the inclined channel to the arc channel and rotates the fan-shaped plate 451, so that the second counterweight ball in the vertical channel moves upward, and the first counterweight ball in the arc channel moves to the bottom of the vertical channel, so that the top second counterweight ball can enter the fixed box 44 as the third counterweight ball 442 and abut the elastic baffle 441, and the material receiving box 42 can also return to its initial horizontal state. In this way, the counterweight balls can be recovered and recycled, so that the material receiving box 42 can return to a horizontal state.

[0042] When coconut flakes and metal impurities fall into the receiving box 42, due to the elastic force of the torsion spring 4211, the receiving box 42 will vibrate, causing the coconut flakes to vibrate out of the receiving box 42 and fall outside the distributing mechanism 5, and causing the metal impurities to move on the electromagnet 424 in the receiving box 42, affecting the adsorption effect of the electromagnet 424. In order to reduce the vibration of the receiving box 42, in some embodiments of the present application, a first spherical airbag 422 abutting against a fixed seat 43 is provided at the bottom of the receiving box 42, and a second spherical airbag 423 is provided at the top of the receiving box 42, the second spherical airbag 423 abuts against a buffer plate 411 away from the conveyor belt 1, the first spherical airbag 422 and the second spherical airbag 423 are connected to each other, and the volume of the first spherical airbag 422 is greater than the volume of the second spherical airbag 423.

[0043] When the receiving box 42 tilts downward, the bottom of the receiving box 42 will squeeze the first spherical airbag 422, and the gas in the first spherical airbag 422 will be transported to the second spherical airbag 423. Since the second spherical airbag 423 is smaller, when it is filled with gas, it will maintain contact with the lowest buffer plate 411 in the drop bin 41 during the expansion process. In this way, the second airbag will reduce the rebound speed of the torsion spring 4211, thereby reducing the vibration of the receiving box 42.

[0044] In some embodiments of this application, please refer to Figure 8 and Fig. 9The material dispensing mechanism 5 includes a first collecting box 56 and a second collecting box located below the material receiving box 42; a slide groove is provided at one end of the electromagnet 424, and a slider 4241 is slidably connected to the inner wall of the slide groove and abuts against the inner wall of the material receiving box 42; a second elastic member connected to the slider 4241 is provided in the slide groove, and the part of the slider 4241 away from the second elastic member is arranged in an arc shape; a fixing rod 425 rotatably connected to the part of the electromagnet 424 close to the slide groove is provided on the inner side wall of the material receiving box 42; an inner wall of the material receiving box 42 abutting against the slider 4241 is provided with a first opening 427 located below the slider 4241; an inner bottom wall of the material receiving box 42 is provided with a second opening 428 located below the slider 4241; a support seat is provided on the inner bottom wall of the material receiving box 42, and a second button 426 electrically connected to the electromagnet 424 is provided on the top of the support seat; and the electromagnet 4 The other end of 24 abuts against the second button 426, and the material dropping bin 41 is provided with a pull rope 412, and the end of the pull rope 412 away from the material dropping bin 41 is connected to the other end of the electromagnet 424; a fixed box 44 is provided on the side wall of the material receiving box 42, and an elastic baffle 441 is provided on the inner bottom wall of one end of the fixed box 44 close to the rotating shaft, and a circulation shell 45 is connected to the bottom of the fixed box 44, and the circulation shell 45 has an inclined channel, an arc channel and a vertical channel that are interconnected. The end of the fixed box 44 away from the rotating column 421 is connected to the inclined channel, a first counterweight ball is provided in the arc channel and a rotating rod is rotatably installed, three fan-shaped dial plates 451 are provided at intervals on the outer peripheral wall of the rotating rod, and a plurality of second counterweight balls are provided in the vertical channel, and a third counterweight ball 442 abutting against the elastic baffle 441 and the second counterweight ball is provided in the fixed box 44.

[0045] When the material receiving box 42 is tilted to a certain angle, the third counterweight ball 442 bends the elastic baffle 441 against which it abuts and quickly rolls to the end of the fixed box 44 away from the rotating column 421, so that the material receiving box 42 overcomes the elastic force and rotates downward to a larger tilt angle. During the movement of the third counterweight ball 442, the pull rope 412 will be stretched straight and the electromagnet 424 will rotate relative to the fixed rod 425. The pull rope 412 will rotate the electromagnet 424 to a nearly vertical position. When the electromagnet 424 rotates, it will disengage from the second button 426, so that the second button 426 returns to the initial state of the electromagnet 424 being powered off, and the metal impurities on the electromagnet 424 will slide off from the first opening 427 and the second opening 428. The second button 426 can be a reset button. When the electromagnet 424 rotates relative to the fixed rod 425 until the slider 4241 corresponds to the first opening 427, the slider 4241 will extend out of the first opening 427 under the action of the second elastic member and slide the metal impurities from the first opening 427 and the second opening 428 into the first collection box 56. The setting of the slider 4241 can make the metal impurities on the electromagnet 424 slide into the first collection box 56 earlier and faster. In the process of the third counterweight ball 442 being limited by the elastic baffle 441, the coconut flakes on the electromagnet 424 will slide into the second collection box through the drop opening. In this way, the structure is simpler, the space occupied is small, and it is easier to separate the coconut flakes and metal impurities. When the drop is completed, the receiving box 42 will return to a horizontal state, and the electromagnet 424 will continue to press the second button 426, and the electromagnet 424 will restore its magnetism.

[0046] In some embodiments of this application, please refer to Figure 1 and Fig.10 The driving mechanism 3 includes a second motor 31 and a feeding body 32. The second motor 31 is installed on the conveyor belt 1 and is electrically connected to the metal detector 2. The feeding body 32 is connected to the second motor 31. An avoidance groove is provided in the feeding body 32. A feeding plate 321 is slidably connected to the inner wall of the avoidance groove. The feeding plate 321 is provided with a third elastic member connected to the inner wall of the avoidance groove. The bottom of the feeding plate 321 is inclined.

[0047] When the metal detector 2 detects that the coconut flakes below contain metal impurities, the second motor 31 is started, and the feeder 32 rotates and pushes the pile of coconut flakes to the receiving mechanism 4. The feeder 32 can rotate 360 ​​degrees to return to the original position to avoid pushing other coconut flakes down during the return journey. The third elastic member can enable the feeder plate 321 to smoothly and fluently rotate to abut or detach from the upper surface of the conveyor belt 1, and under the action of the third elastic member, the feeder plate 321 is closely attached to the surface of the conveyor belt 1 to prevent the coconut flakes from being scraped and lost. The bottom of the feeder plate 321 is tilted to better scrape the coconut flakes.

[0048] Since the feeding body 32 still has the risk of pushing the shredded coconut to the opposite side of the receiving mechanism 4 or the second motor 31, in some embodiments of the present application, please refer to Fig.11 and Fig.12 The driving mechanism 3 includes a mounting frame 33, a mounting block 34, a cylinder 35 and a push plate 36. The mounting frame 33 is installed on the conveyor belt 1. The mounting block 34 is arranged on the mounting frame 33. A sliding member 341 is movably inserted in the mounting block 34. A protrusion 341 is provided at one end of the sliding member 341 away from the mounting block 34; the cylinder 35 is arranged on the mounting block 34, and the cylinder 35 is connected to a pushing member 351. One end of the pushing member 351 away from the cylinder 35 is rotatably connected to a connecting plate 37, and the connecting plate 37 is rotatably connected to the protrusion 3411; the push plate 36 is connected to the connecting plate 37, and the connecting plate 37 is provided with a blocking block 371 that can abut the sliding member 341.

[0049] The cylinder 35 is started to drive the push member 351 to move, and when the bottom of the push plate 36 contacts the surface of the transmission belt, the stop block 371 also contacts the sliding member 341. The push plate 36 pushes the coconut flakes to the receiving mechanism 4, and when the push plate 36 returns, the stop block 371 is separated from the sliding member 341, and the connecting plate 37 rotates, and the push plate 36 moves upward and away from other coconut flakes on the conveyor belt 1.

[0050] Working principle: If the metal detector 2 detects that there are metal impurities in the coconut flakes, the driving mechanism 3 will be activated and the pile of coconut flakes will enter the receiving mechanism 4; the top and side walls of the receiving box 42 are respectively provided with a receiving port and a dropping port. When the coconut flakes and metal impurities fall from the receiving port onto the electromagnet 424 in the receiving box 42, as the amount of coconut flakes increases, the receiving box 42 slowly tilts. When the receiving box 42 is slightly tilted, the tilt angle is small, and the powdered coconut flakes will first slide from the dropping port to the dividing mechanism 5 below. When the powdered coconut flakes slide in the receiving box 42, the pressure on the docking box 42 is small, and the iron filings will stay stably and be adsorbed in the horizontal or approximately horizontal receiving box 42 to prevent the iron filings from rolling too much relative to the electromagnet 424 after falling. As piles of powdered coconut flakes fall into the receiving box 42, the iron filings in the receiving box 42 will increase, and the receiving box 42 will resist the elastic force of the torsion spring 4211 and tilt downward. When the number of iron filings is sufficient, the electromagnet 424 will lose power and magnetism, and the iron filings will slide from the drop-out opening of the receiving box 42 to the material separation mechanism 5. The coconut flakes and metal impurities that fall into the material separation mechanism 5 successively will be separated and fall to different positions.
