Description

Technical Field

[0001] This utility model relates to the field of material screening equipment technology, and in particular to a vibrating metal detection and separation device. Background Technology

[0002] During the production and processing of materials such as plastic granules, metallic impurities are often mixed into the materials. These impurities not only affect the quality of the final product, but may also cause wear or damage to subsequent processing equipment (such as extruders, injection molding machines, etc.).

[0003] Existing metal detection and separation equipment can only introduce one type of plastic granules for metal detection and separation. It does not have a mixing function. When the separated plastic granules need to be mixed for use, the two different plastic granules need to be mixed in a certain proportion, which adds an extra production process and reduces production efficiency. Furthermore, in existing metal detection and separation equipment, a lot of material remains in the separated metal impurities. These residual materials need to be separated again after each export. Due to the presence of a small amount of material, the metal detection and separation equipment does not separate the materials finely enough. At this time, the separation method often adopts manual shaking separation, which is inefficient and has poor separation effect. Summary of the Invention

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0020] This embodiment: like Figure 1 As for Figure 2 As shown, a vibrating metal detection and separation device includes a first frame 1, a second frame 2, a discharge bin 3, a metal bin 4, a feeding mechanism 5, a vibration mechanism 6, and a detection mechanism 7. The first frame 1 has a discharge bin 3, with a collection bin 8 connected to its bottom. A first discharge pipe 9 is connected to one side of the collection bin 8 and is connected to an external material collection point or material usage point (not shown). The second frame 2 is mounted on the top surface of the discharge bin 3, along with the detection mechanism 7 located adjacent to the second frame 2. The second frame 2 is equipped with... There is a feeding mechanism 5, and a vibration mechanism 6 is also provided on the second frame 2. The vibration mechanism 6 is located below the feeding mechanism 5. The feeding mechanism 5 is connected to the detection mechanism 7 through the guide pipe 10. The vibration mechanism 6 is connected to the guide pipe 10 in a transmission connection. A metal bin 4 is provided on one side of the first frame 1. A second discharge pipe 11 is connected to one side of the metal bin 4. The second discharge pipe 11 is connected to an external material collection point (not shown in the figure). The detection mechanism 7 is connected to the discharge bin 3 through the material connecting pipe 12 and to the metal bin 4 through the metal connecting pipe 13.

[0021] like Figure 1 As for Figure 3 As shown, specifically, the feeding mechanism 5 includes a hopper 51 and two feeding bins 52. The hopper 51 is located at the top of the first frame 1. The bottom of the hopper 51 is connected to a guide pipe 10. The two feeding bins 52 are connected to the top of the hopper 51 through opening and closing valves 53. The opening and closing valves 53 are used to open and close the feeding bins 521 to discharge material. At the same time, by adjusting the opening degree of the two opening and closing valves 53, two materials can be mixed by entering the hopper 51 in proportion. The feeding hopper 52 also includes a feeding hopper 521 connected to the opening and closing valve 53. The top of the feeding hopper 521 is fixed with a feeding top cover 522 that can be opened and closed by three first latches 54. The three first latches 54 are arranged in a ring at equal intervals. When there is an abnormality in the feeding hopper 521, or when materials need to be manually added, the first latches 54 can be opened to open the feeding top cover 522 for maintenance or manual feeding. A negative pressure pipe 5221 is connected to the top cover 522. The negative pressure pipe 5221 is used to provide negative pressure in the feed hopper 521. A feed pipe 5211 is connected to the side of the feed hopper 521. The feed pipe 5211 is used for material to enter the feed hopper 521. The feed pipe 5211 is connected to an external material source (not shown in the figure) that requires metal separation, and the negative pressure pipe 5221 is connected to an external negative pressure device (not shown in the figure). When the negative pressure device is started, a negative pressure is generated inside the negative pressure pipe 5221, which in turn generates a negative pressure inside the feed hopper 521 and the feed pipe 5211, so that the material from the external material source flows into the feed hopper 521 from the feed pipe 5211. The operation is convenient and does not require manual feeding.

[0022] Meanwhile, in this embodiment, the number of feeding hoppers 52 can be set according to the need to mix various different materials; When mixing of materials is not required, the same materials can be added to both feed hoppers 52, which is highly practical.

[0023] like Figure 1 He Ru Figure 4 As shown, specifically, the vibration mechanism 6 includes four rectangularly distributed support columns 61 on the second frame 2. Vibration springs 62 are respectively sleeved on the four support columns 61. Vibration seats 63 are fixedly connected to the top of the vibration springs 62. Transmission plates 65 are fixedly connected to the top of the vibration seats 63 through two L-shaped connecting plates 64. The bottom of the collecting hopper 51 is connected to a guide pipe 10. The transmission plate 65 is fixedly connected to the guide pipe 10. A vibration motor 66 is also provided on the vibration seat 63. Among them, the vibration spring 62 is used to buffer the vibration impact of the vibration seat 63, while enhancing the vibration amplitude of the guide tube 10 and improving the material conveying efficiency. The material in the collecting hopper 51 will fall into the guide pipe 10. The guide pipe 10 is at a certain angle. The material falling into the guide pipe 10 will not move. It is necessary to start the vibration motor 66 to drive the vibration seat 63 to vibrate up and down through the vibration spring 62, which in turn drives the two connected L-shaped connecting plates 64, the transmission plate 65 and the guide pipe 10 to vibrate. When the guide pipe 10 vibrates, the material falling on the guide pipe 10 will move along the inclined direction, which makes the conveying stable and prevents the metal impurities in the material box from accumulating together. At the same time, it can avoid material blockage.

[0024] like Figure 1 ,like Figure 7 He Ru Figure 8As shown, specifically, the detection mechanism 7 includes a detection chamber 71, an electromagnetic identification unit 72, and a connecting hopper 73. The top of the discharge chamber 3 is fixedly connected to a material connecting pipe 12, and the top of the material connecting pipe 12 is fixedly connected to the detection chamber 71. The top of the detection chamber 71 is connected to the connecting hopper 73 through an opening and closing mechanism 74. One side of the connecting hopper 73 has a connecting opening, through which the guide pipe 10 passes. An electromagnetic identification unit 72 is provided on one side of the detection chamber 71. The electromagnetic identification unit 72 is used for real-time metal detection. The top of the material connecting pipe 12 is located inside the detection chamber 71 and a separation mechanism 75 is also provided. One side of the separation mechanism 75 is connected to one end of a metal connecting pipe 13, and the other end of the metal connecting pipe 13 is connected to a metal chamber 4. like Figure 1 ,like Figure 7 He Ru Figure 8 As shown, more specifically, the separation mechanism 75 includes a separation chamber 751 connected to the metal connecting pipe 13 and the material connecting pipe 12. A separation rotating rod 752 is rotatably arranged inside the separation chamber 751. A separation plate 753 that can drive the material to flow into the material connecting pipe 12 or the metal connecting pipe 13 is fixedly sleeved on the separation rotating rod 752. A transmission block 754 is fixedly connected to one end of the separation rotating rod 752. A separation driving cylinder 755 is arranged on the outside of the separation chamber 751. The telescopic shaft of the separation driving cylinder 755 is fixedly connected to one end of the transmission block 754. A detection tube 76 is arranged between the top of the separation chamber 751 and the connecting hopper 73. An electromagnetic identification unit 72 is located on one side of the detection tube 76. When material containing metal impurities enters the detection tube 76 through the connecting hopper 73 via the guide pipe 10, the material passing through the connecting pipe will be detected by the electromagnetic identification unit 72. The electromagnetic identification unit 72 drives the separation drive cylinder 755 to operate. The operation of the separation drive cylinder 755 drives its telescopic rod to drive the separation block to rotate around the separation rotating rod 752. The separation rotating rod 752 drives the separation plate 753 to rotate, thereby changing the material flow direction and causing part of the material containing metal impurities to fall into the metal connecting pipe 13, and then causing the material containing metal impurities to fall into the metal bin 4.

[0025] like Figure 1 He Ru Figure 5 As shown, more specifically, the opening and closing mechanism 74 includes a connecting plate 741 disposed on the top of the detection chamber 71. The connecting plate 741 has a first opening for connecting the detection tube 76 and the connecting bucket 73. Push grooves communicating with the first opening are provided on opposite sides of the connecting plate 741. An opening and closing plate 742 is slidably disposed in the push groove. The opening and closing plate 742 has a second opening aligned with the first opening. Both ends of the opening and closing plate 742 also have limiting parts 7421 that limit the connecting plate 741. The limiting parts 7421 can prevent the opening and closing plate 742 from disengaging from the push groove when it slides. When the limiting part 7421 moves to the end of the connecting plate 741, it can align the connecting plate 741 with the first opening, the opening and closing plate 742 and the second opening, adjust the position of the opening and closing plate 742 in the push groove, and also adjust the size of the material channel between the detection chamber 71 and the connecting hopper 73 to control the flow rate of the material falling in.

[0026] like Figure 1 He Ru Figure 2 As shown, specifically, a first observation window 31 is provided on one side of the discharge bin 3, a second observation window 41 is provided on one side of the metal bin 4, and a third observation window 511 is provided on one side of the collecting hopper 51. The first observation window 31, the second observation window 41 and the third observation window 511 are elliptical, which makes it easier for staff to observe the internal material status. like Figure 1 He Ru Figure 5 As shown, specifically, the top of the discharge hopper 3 is hinged to a first door panel 32 that can be opened and closed. A rectangular observation window 321 is provided on the door panel. The rectangular observation window 321 has the same function as the first, second and third observation windows, which makes it convenient for staff to observe the internal material status. The first door panel 32 is also equipped with a handle 322, which makes it convenient to inspect the inside of the discharge hopper 3. The bottom of the metal compartment 4 is hinged with a second door panel 42 that can be opened and closed. Two second latches 43 are provided on one side of the metal compartment 4 at intervals to engage with the second door panel 42 to close, so as to facilitate the opening of the metal compartment 4 and discharge the metal impurities inside the metal compartment 4. The second discharge pipe 11 and the second door panel 42 are at a certain height. A metal detection unit 14 is also provided on one side of the metal bin 4. The height of the metal detection unit 14 is lower than the height of the second discharge pipe 11. The metal bin 4 is at a certain angle. The material falling into the metal bin 4 from the metal connecting pipe 13 will fall into the metal bin 4 from the highest point of the angle and roll along the inclined direction to the lowest point of the angle of the metal bin 4. Since the density of metal impurities is relatively large compared with plastic particles, the metal impurities will accumulate at the bottom of the metal bin 4 while rolling on the slope and will not run out beyond the second discharge pipe 11. The metal detection unit 14 is used to detect whether the content of metal impurities in the metal bin 4 exceeds the height of the metal detection unit 14 (close to the second discharge pipe 11); When the metal content in the metal bin 4 exceeds the inspection height of the metal detection unit 14, that is, when a certain amount is reached, the metal detection unit 14 will issue a warning alarm, reminding the operator to open the second latch 43 and open the second door 42 in time to discharge the metal impurities in the metal bin 4. The content of the separated material is less than that of the material remaining after traditional separation, which can effectively reduce the difficulty of secondary separation after separation. Meanwhile, when the metal content in the metal bin 4 does not exceed the inspection height of the metal detection unit 14, the material falling into the metal bin 4 will fall through the second discharge pipe 11 to the material collection point for collection, which can effectively reduce the frequency of secondary material separation and effectively enhance separation efficiency and production efficiency.

[0027] like Figure 2 He Ru Figure 6 As shown, specifically, the first discharge pipe 9 has several rectangular array of through holes 91. When the through holes 91 are smaller than the material particles, the material can be prevented from escaping through the through holes 91. The first discharge pipe 9 is also connected to an external negative pressure device (not shown in the figure). At the same time, in this embodiment, the first discharge pipe 9 is set at an angle upward. Combined with the design that the through holes 91 are smaller than the material particles, the material will gather in the discharge bin 3 due to gravity, so that the discharge bin 3 has a material storage function. When the material inside the discharge bin 3 is needed, the external negative pressure device provides negative pressure to the first discharge pipe 9. The external gas flows towards the output end of the first discharge pipe 9 through the through holes 91. The airflow will drive the material concentrated in the collection bin 8 to move towards the output end of the first discharge pipe, thereby realizing the use of the material at any time.

[0028] like Figure 1 As shown, a control switch 15 is mounted on one side of the second frame 2 via an L-shaped mounting plate. The control switch 15 is electrically connected to the vibration motor 66, the separation drive cylinder 755, the electromagnetic identification unit 72, and the metal detection unit 14. The control switch 15 enables centralized control of the equipment, making operation simple and convenient.

[0029] like Figure 1 He Ru Figure 2 As shown, more specifically, the bottom four corners of the first frame 1 are provided with four lockable guide wheels 16, which facilitate the movement and fixation of the equipment.

[0030] Working principle: In use, by activating the external negative pressure device, negative pressure is generated in the negative pressure pipe 5221 on the feed top cover 522, so that the two different materials to be processed enter the corresponding feed hopper 521 through the feed pipe 5211 respectively. By adjusting the opening degree of the two opening and closing valves 53, the ratio of the two materials entering the collection hopper 51 is controlled to achieve material mixing. At the same time, the vibration motor 66 is started, and the vibration motor 66 drives the vibration seat 63 to vibrate. The vibration is transmitted to the guide pipe 10 through the transmission plate 65, so that the mixture falling into the guide pipe 10 is conveyed to the connecting bucket 73 of the detection mechanism 7 under the action of vibration. The material enters the detection tube 76 through the connecting hopper 73. The electromagnetic identification unit 72 detects the material in real time. When no metal impurities are detected, the separation plate 753 remains in its initial state. The material enters the discharge hopper 3 through the material connecting pipe 12 and is collected in the collection hopper 8. When metal impurities are detected, the control switch 15 controls the separation drive cylinder 755 to move, pushing the transmission block 754 to drive the separation rod 752 to rotate, causing the separation plate 753 to turn towards the material connection pipe 12, and closing the material connection pipe 12 channel. The metal impurities enter the metal connection pipe 13 with the material and finally fall into the metal bin 4. When the material in the metal bin 4 accumulates to the height of the metal detection unit 14, the metal detection unit 14 will detect that the metal impurity content is too high and issue a warning alarm to remind the operator to open the second door panel 42 to clean and discharge the metal impurities in the metal bin 4.

[0031] When the material in the discharge bin 3 is needed, the external negative pressure device is activated to generate negative pressure in the first discharge pipe 9. Through the ventilation effect of the through hole 91, the material in the collection bin moves toward the first discharge pipe 9, thereby enabling the material to be used at any time.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
