Description

TECHNICAL FIELD

[0001] The application relates to the technical field of metal detection, in particular to a metal detection device for shredded coconut processing. BACKGROUND

[0002] Shredded coconut refers to a kind of food dried and ground into silk or powder from the flesh of coconut. It is very popular in Guangdong, Hainan and Fujian of China, and is used to make various desserts, cakes and dishes.

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

[0027] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail with reference to the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0028] Please refer to Figures 1 to 12The application provides a metal detection device for processing shredded coconut, which comprises a conveying belt 1, a metal detector 2, a receiving mechanism 4, a driving mechanism 3 and a distributing mechanism 5. The metal detector 2 is connected with the conveying belt 1 and used for detecting the shredded coconut on the conveying belt 1. The receiving mechanism 4 is arranged below the conveying belt 1 and comprises a fixed seat 43, a 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 with the receiving box 42, and the other end is rotatably connected with the mounting plate 431. The rotating column 421 is sleeved with a torsional spring 4211. The two ends of the torsional spring 4211 are respectively connected with the receiving box 42 and the mounting plate 431. The receiving box 42 is internally provided with an electromagnet 424. The driving mechanism 3 is electrically connected with the metal detector 2 and used for moving the shredded coconut containing metal impurities to the receiving mechanism 4. The distributing mechanism 5 is arranged below the receiving box 42 and used for receiving the shredded coconut when the electromagnet 424 is electrified, receiving the metal impurities when the electromagnet 424 is de-energized and separating the shredded coconut from the metal impurities.

[0029] In the embodiments provided in the application, refer to Figure 1 and Figure 2When the powdered coconut is conveyed on the conveyor belt 1 to the below of the metal detector 2, if the coconut contains metal impurities, the driving mechanism 3 is actuated and the pile of coconut is made to enter the receiving mechanism 4, the metal impurities can include iron filings and other impurities that can be attracted by a magnet; the top and side wall of the receiving box 42 are respectively provided with a receiving port and a discharging port, when the coconut and metal impurities fall into the electromagnet 424 in the receiving box 42 from the receiving port, as the coconut increases, the receiving box 42 slowly tilts, when the receiving box 42 slightly tilts, the tilting angle is small, the powdered coconut will first slide from the discharging port to the below distribution mechanism 5, the pressure of the powdered coconut on the receiving box 42 is small when the powdered coconut slides in the receiving box 42, and the iron filings will be stably stopped and adsorbed in the receiving box 42 which is horizontal or approximately horizontal, preventing the iron filings from falling and rolling relatively to the electromagnet 424 with too large an amplitude. As one pile after another of powdered coconut falls 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 amount of iron filings is sufficient to make the electromagnet 424 lose power and lose magnetism, the iron filings will slide from the discharging port of the receiving box 42 to the distribution mechanism 5; wherein a weight sensor electrically connected to the electromagnet 424 can be arranged in the receiving box 42, after the amount of iron filings in the receiving box 42 increases, the total weight becomes larger, the weight sensor can transmit a weight signal to the controller, and the controller will make the electromagnet 424 lose power. Of course, after the amount of iron filings increases, the receiving box 42 will tilt, and an encoder can also be arranged on the receiving box 42, when the receiving box 42 tilts to a predetermined angle, the encoder can transmit an angle signal to the controller, and the controller makes the electromagnet 424 lose power. When the iron filings and other metal impurities fall into the distribution mechanism 5, the receiving box 42 returns to the horizontal position under the action of the torsion spring 4211, and the electromagnet 424 restores the magnetism. The coconut and metal impurities that fall into the distribution mechanism 5 in succession will be separated and fall into different positions.

[0030] The coconut and metal impurities falling from the conveyor belt 1 will form a certain impact force on the electromagnet 424 in the receiving box 42, there is a risk of damaging 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 further comprises a discharging bin 41, the discharging bin 41 is connected to the conveyor belt 1 and located above the receiving box 42, a plurality of inclined buffer plates 411 are arranged in the discharging bin 41, the inclination angles of the plurality of buffer plates 411 in the discharging bin 41 from top to bottom decrease in turn. When the coconut and metal impurities fall from the uppermost buffer plate 411 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 below electromagnet 424 will decrease.

[0031] In some embodiments of the present application, please refer to Figure 2 and Figure 5, the distributing mechanism 5 comprises a mounting base 51, a distributing table 52, a first collecting box, a second collecting box and a blocking mechanism, the top of the mounting base 51 is provided with a first button 511, the first button 511 is electrically connected with the electromagnet 424; the distributing table 52 is arranged in an inclined manner and is connected with the mounting base 51, the distributing table 52 has a first material falling channel 521 and a second material falling channel which are communicated with each other, the first material falling channel 521 is located below the collecting box 42, the middle part of the second material falling channel is provided with a partition body, the partition body divides the second material falling channel into a first distributing channel 522 and a second distributing channel 523, the extending direction of the first distributing channel 522 coincides with the extending direction of the first material falling channel 521; the first collecting box is located below the distributing table 52 and corresponds to the first distributing channel 522; the second collecting box is located below the distributing table 52 and corresponds to the second distributing channel 523; the blocking mechanism is arranged on the distributing table 52 and is used for closing and opening the first distributing channel 522, so that the shredded coconut can enter one of the first collecting box and the second collecting box, and the metal impurities can enter the other one of the first collecting box and the second collecting box.

[0032] The shredded coconut will first fall into the first material falling channel 521, when the blocking mechanism opens the first distributing channel 522, the shredded coconut will pass through the first distributing channel 522 and fall into the first collecting box; when the blocking mechanism closes the first distributing channel 522, the shredded coconut will be guided by the blocking mechanism to the second distributing channel 523 and slide to the second collecting box; when the collecting box 42 is inclined to press the first button 511, the electromagnet 424 will lose electricity and lose magnetism, the metal impurities will slide to the first material falling channel 521, the blocking mechanism will be moved from opening the first distributing channel 522 to closing the first distributing channel 522, so that the metal impurities pass through the second distributing channel 523 and slide to the second collecting box, realizing that the metal impurities and the shredded coconut fall to different positions and successfully separating the shredded coconut and the metal impurities. After the collecting box 42 presses the first button 511, the blocking mechanism will also be moved 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 to the first collecting box, which can also realize that the metal impurities and the shredded coconut fall to different positions. Among them, the first button 511 can be a reset button, when the collecting box 42 rotates upward under the action of the torsion spring 4211, the first button 511 returns to the original position, the circuit in which the electromagnet 424 is located will restore to be closed, and the electromagnet 424 restores to be magnetic after being powered.

[0033] Further, please refer to Figure 7 The blocking mechanism comprises a diversion plate 53, a driving motor 5221 and a button switch, the diversion plate 53 is arranged on the distributing table 52. The driving motor 5221 is installed on the distributing table 52 and is connected with the diversion plate 53, which can make the diversion plate 53 rotate to abut against the partition body to close the first distributing channel 522; the button switch is arranged on the top of the mounting base 51 and is electrically connected with the driving motor 5221.

[0034] When the receiving box 42 presses the first button 511 and the button switch, the driving motor 5221 starts and rotates the diversion plate 53 by a certain angle and abuts against the partition, thereby closing the first material distribution channel 522, and the diversion plate 53 guides the metal impurities to the second material distribution channel 523. When the receiving box 42 releases the first button 511 and the button switch, the driving motor 5221 reverses and makes the diversion plate 53 return to the initial position of opening the first material distribution channel 522. The driving motor 5221 can be a servo motor.

[0035] It can be understood that, referring to Figure 5 , the plugging mechanism can further include the diversion plate 53 and the first elastic member 531, the diversion plate 53 is rotatably installed on the upper surface of the material distribution table 52, and the two ends of the first elastic member 531 are respectively connected to the diversion plate 53 and the material distribution table 52, so that the diversion plate 53 abuts against the partition to close the first material distribution channel 522.

[0036] In the process of the coconut rind sliding, since the powdered coconut rind is light and in a flowing state, the impact force of the coconut rind on the diversion plate 53 is small, which cannot overcome the elastic force of the first elastic member 531, and the coconut rind is guided to the second material distribution channel 523 and falls into the second receiving box. Subsequently, in the process of the metal impurities sliding, since the metal impurities are heavy, the impact force of the metal impurities on the diversion plate 53 is large and greater than the elastic force of the first elastic member 531, the metal impurities push away the diversion plate 53 and make the diversion plate 53 rotate to open the first material distribution channel 522, and the metal impurities fall into the first receiving box from the first material distribution channel 522.

[0037] Referring to Figure 5 and Figure 6 , since the metal impurities are continuously flowing when impacting the diversion plate 53, as the metal impurities continuously enter the first material distribution channel 522, the impact force of the remaining small amount of metal impurities becomes small, and a small amount of metal impurities is guided by the diversion plate 53 to the first material distribution channel 521. In order to prevent the small amount of metal impurities and the coconut rind from falling into the same position and being unable to be separated, the magnetic plate 5231 can be obliquely installed at a position of the second material distribution channel 523 away from the first material distribution channel 521, the coconut rind is guided away by the magnetic plate 5231, and the small amount of metal impurities is adsorbed by the magnetic plate 5231, thereby preventing the small amount of metal impurities and the coconut rind from being mixed.

[0038] Since the metal detector 2 will detect multiple piles of shredded coconut with metal impurities, the magnetic plate 5231 will adsorb the metal impurities entering the second material distribution channel 523 multiple times. The volume of the magnetic plate 5231 is fixed and cannot adsorb more metal impurities. In order to adapt to the adsorption of metal impurities multiple times and make the metal impurities leave the second material distribution channel 523 and separate from the shredded coconut, in some embodiments of the present application, the second material collecting box has a first accommodating cavity and a second accommodating cavity, and the first accommodating cavity is located below the material guiding plate 55. One end of the partition body away from the first material falling channel 521 is provided with an accommodating groove, and the accommodating groove is provided with a first motor 541. The first motor 541 is connected with a magnetic column 5411 located in the second material distribution channel 523. The second material distribution channel 523 is provided with a guide plate 5232 close to the second material collecting box. The guide plate 5232 is inclined to guide the shredded coconut to the second accommodating cavity. The top of the guide plate 5232 is fixedly connected with an inclined material guiding plate 55. The material guiding plate 55 has a scraping end close to the magnetic column 5411. The magnetic column 5411 is at least partially located above the scraping end.

[0039] The bottom of the magnetic column 5411 and the surface of the second material distribution channel 523 can be spaced apart by a small distance. When the metal impurities slide close to the magnetic column 5411 or contact 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 inclined downward material guiding plate 55. With the rotation of the magnetic column 5411, the outer metal impurities will be scraped off to the upper surface of the material guiding plate 55. The metal impurities will slide down the material guiding plate 55 to the first accommodating cavity below. The shredded coconut will be guided by the guide plate 5232 to the second accommodating cavity, which can further separate the shredded coconut and the metal impurities.

[0040] In some embodiments of the present application, please refer to Figure 2 and Figure 3 The side wall of the material collecting box 42 is provided with a fixed box 44. The inner bottom wall of one end of the fixed box 44 close to the rotating shaft is provided with an elastic baffle 441. The bottom of the fixed box 44 is connected with a circulating housing 45. The circulating housing 45 has an inclined channel, a circular arc channel and a vertical channel which are in communication with each other. One end of the fixed box 44 away from the rotating column 421 is in communication with the inclined channel. The circular arc channel is provided with a first counterweight ball and a rotating rod which is rotatably installed. The outer circumferential wall of the rotating rod is provided with three sector-shaped dials 451 at intervals. The vertical channel is provided with a plurality of second counterweight balls. The fixed box 44 is provided with a third counterweight ball 442 which abuts against the elastic baffle 441 and the second counterweight ball.

[0041] When the receiving box 42 is inclined to about thirty degrees, the third counterweight ball 442 in the fixed box 44 presses 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 powerfully, and can also make the receiving box 42 overcome the elastic force of the torsional spring 4211 and quickly incline downward to press the first button 511, reduce the time of the receiving box 42 in a large inclination state, increase the time of the receiving box 42 in a small inclination state, further prevent the activity range of the metal impurities after falling on the electromagnet 424 in the receiving box 42 from being too large, so as to more stably adsorb more metal impurities and improve the adsorption effect on the falling metal impurities. When the metal impurities slide down, the receiving box 42 rotates upward, the third counterweight ball 442 rolls from the inclined channel to the circular-arc-shaped channel and rotates the sector-shaped plate 451, so that the second counterweight ball in the vertical channel moves upward, the first counterweight ball in the circular-arc-shaped channel moves to the lowermost part of the vertical channel, and then the uppermost second counterweight ball can enter the fixed box 44 as the third counterweight ball 442 and abut against the elastic baffle 441, and the receiving box 42 can also return to the initial horizontal state, so that the counterweight balls can be recycled and used circularly, and the receiving box 42 can return to the horizontal state.

[0042] When the shredded coconut and metal impurities fall into the receiving box 42, the receiving box 42 will vibrate due to the elastic force of the torsional spring 4211, which will make the shredded coconut vibrate out of the receiving box 42 and fall to the outside of the distributing mechanism 5, and will make the metal impurities 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, the bottom of the receiving box 42 is provided with a first spherical air bag 422 abutting against the fixed seat 43, and the top of the receiving box 42 is provided with a second spherical air bag 423 abutting against the buffer plate 411 away from the conveying belt 1, the first spherical air bag 422 and the second spherical air bag 423 are in communication with each other, and the volume of the first spherical air bag 422 is greater than that of the second spherical air bag 423.

[0043] When the receiving box 42 inclines downward, the bottom of the receiving box 42 will extrude the first spherical air bag 422, and the gas in the first spherical air bag 422 is transported to the second spherical air bag 423. Since the second spherical air bag 423 is smaller, when the inside is filled with gas, it will keep in contact with the lowermost buffer plate 411 in the dropping bin 41 in the process of inflation, so that the second air bag can reduce the rebound speed of the torsional spring 4211, and in turn reduce the vibration of the receiving box 42.

[0044] In some embodiments of the present application, please refer to Figure 8 and Figure 9The distributing mechanism 5 comprises a first collecting box 56 and a second collecting box located below the receiving box 42; one end of the electromagnet 424 is provided with a sliding groove, an inner wall of the sliding groove is slidably connected with a sliding block 4241 abutting against an inner wall of the receiving box 42, a second elastic member connected with the sliding block 4241 is arranged in the sliding groove, a portion of the sliding block 4241 away from the second elastic member is arranged in an arc shape, a fixed rod 425 rotationally connected with the portion of the electromagnet 424 close to the sliding groove is arranged on an inner side wall of the receiving box 42, an inner wall of the receiving box 42 abutting against the sliding block 4241 is provided with a first opening 427 located below the sliding block 4241, an inner bottom wall of the receiving box 42 is provided with a second opening 428 located below the sliding block 4241, the inner bottom wall of the receiving box 42 is provided with a support seat, a top portion of the support seat is provided with a second button 426 electrically connected with the electromagnet 424, the other end of the electromagnet 424 abuts against the second button 426, the blanking bin 41 is provided with a pull rope 412, one end of the pull rope 412 away from the blanking bin 41 is connected with the other end of the electromagnet 424; a side wall of the receiving box 42 is provided with a fixed box 44, an inner bottom wall of one end of the fixed box 44 close to the rotating shaft is provided with an elastic baffle 441, a bottom portion of the fixed box 44 is connected with a circulating housing 45, the circulating housing 45 has an inclined channel, a circular-arc-shaped channel and a vertical channel which are in communication with each other, one end of the fixed box 44 away from the rotating column 421 is in communication with the inclined channel, a first counterweight ball is arranged in the circular-arc-shaped channel and a rotating rod is rotationally arranged in the circular-arc-shaped channel, three sector-shaped dials 451 are arranged at intervals on an outer circumferential wall of the rotating rod, a plurality of second counterweight balls are arranged in the vertical channel, a third counterweight ball 442 abutting against the elastic baffle 441 and the second counterweight balls is arranged in the fixed box 44.

[0045] When the receiving box 42 is tilted to a certain angle, the third counterweight ball 442 presses and bends the elastic baffle 441 against it and quickly rolls to the end of the fixed box 44 away from the rotating column 421, so that the receiving box 42 overcomes the elastic force and turns downward to a larger inclination angle. During the movement of the third counterweight ball 442, the pull rope 412 will be straightened and make the electromagnet 424 rotate relative to the fixed rod 425, the pull rope 412 will make the electromagnet 424 rotate to be close to vertical, and the electromagnet 424 will be separated from the second button 426 when it rotates, so that the second button 426 returns to the initial state of making the electromagnet 424 de-energized, and the metal impurities on the electromagnet 424 will fall 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 to make the sliding block 4241 correspond to the first opening 427, the sliding block 4241 will extend out of the first opening 427 under the action of the second elastic member and make the metal impurities fall into the first collecting box 56 from the first opening 427 and the second opening 428, respectively. The setting of the sliding block 4241 can make the metal impurities on the electromagnet 424 fall into the first collecting box 56 earlier and faster. During the limiting of the third counterweight ball 442 by the elastic baffle 441, the shredded coconut on the electromagnet 424 will fall into the second collecting box through the falling port, so that the structure is simpler, occupies less space, and is easier to separate the shredded coconut and the metal impurities. When the falling is completed, the receiving box 42 will return to the horizontal state, and the electromagnet 424 will continue to press the second button 426, and the electromagnet 424 will restore the magnetic property.

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

[0047] When the metal detector 2 detects that the shredded coconut below contains metal impurities, the second motor 31 is started, and the feeding body 32 rotates and pushes the pile of shredded coconut to fall to the receiving mechanism 4. The feeding body 32 can rotate 360 degrees to return to the original position, so as to avoid pushing other shredded coconut to fall during the return. The third elastic member can make the feeding plate 321 smoothly and smoothly rotate to abut or separate from the upper surface of the conveying belt 1, and the feeding plate 321 is tightly attached to the surface of the conveying belt 1 under the action of the third elastic member, so as to prevent the shredded coconut from being scraped and lost, and the bottom of the feeding plate 321 is inclined, so as to better scrape the shredded coconut.

[0048] Since there is still a risk that the feeding body 32 will push the shredded coconut to fall to the opposite side of the receiving mechanism 4 or the opposite side of the second motor 31, in some embodiments of the present application, please refer toFigure 11 and Figure 12 The driving mechanism 3 comprises a mounting frame 33, a mounting block 34, a cylinder 35 and a pushing plate 36. The mounting frame 33 is mounted on the conveying belt 1. The mounting block 34 is arranged on the mounting frame 33. A sliding piece 341 is movably arranged in the mounting block 34. The sliding piece 341 is provided with a protrusion 3411 at an end away from the mounting block 34. The cylinder 35 is arranged on the mounting block 34. The cylinder 35 is connected with a pushing piece 351. The pushing piece 351 is rotatably connected with a connecting plate 37 at an end away from the cylinder 35. The connecting plate 37 is rotatably connected with the protrusion 3411. The pushing plate 36 is connected with the connecting plate 37. The connecting plate 37 is provided with a blocking block 371 capable of abutting against the sliding piece 341.

[0049] The cylinder 35 drives the pushing piece 351 to move. When the bottom of the pushing plate 36 contacts the surface of the conveying belt, the blocking block 371 also contacts the sliding piece 341. The pushing plate 36 directly pushes the shredded coconut to fall into the receiving mechanism 4. When the pushing plate 36 returns, the blocking block 371 is separated from the sliding piece 341. The connecting plate 37 rotates. The pushing plate 36 will move upward and away from other shredded coconut on the conveying belt 1.

[0050] Working principle: If the metal detector 2 detects that the shredded coconut contains metal impurities, the driving mechanism 3 will act and make the pile of shredded coconut enter the receiving mechanism 4. The top and side wall of the receiving box 42 are respectively provided with a receiving port and a discharging port. When the shredded coconut and metal impurities fall into the electromagnet 424 in the receiving box 42 from the receiving port, the receiving box 42 slowly tilts as the shredded coconut increases. When the receiving box 42 slightly tilts, the angle of inclination is small. The powdered shredded coconut will first slide from the discharging port to the distribution mechanism 5 below. The pressure of the powdered shredded coconut on the receiving box 42 is small when it slides in the receiving box 42. The iron scraps will be stably stopped and adsorbed in the receiving box 42 which is horizontal or approximately horizontal, preventing the iron scraps from falling and rolling relatively to the electromagnet 424 with too large an amplitude. As more and more piles of powdered shredded coconut fall into the receiving box 42, the iron scraps 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 amount of iron scraps is sufficient, the electromagnet 424 will lose power and lose magnetism. The iron scraps will slide from the discharging port of the receiving box 42 to the distribution mechanism 5. The shredded coconut and metal impurities falling into the distribution mechanism 5 in succession will be separated and fall into different positions.
