[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1

[0020] like Figure 1-Figure 7 As shown, this embodiment discloses a bidirectional inertial vibrating feeder, including a connecting component 1 for constraining the position of materials, a fastening sleeve 2 is connected to the connecting component 1, the fastening sleeve 2 ensures the tightness of the connection of the connecting component 1 and improves the stability of the connecting component 1 when in use, one end of the fastening sleeve 2 is connected to a vibration damping component 8, and the end of the vibration damping component 8 away from the fastening sleeve 2 is connected to a support portion 4. In this embodiment, the support portion 4 is preferably an I-beam to ensure that the connecting component 1 does not tip over when conveying materials.

[0021] The connecting component 1 includes a protective shell 101, a vibration cavity 1011 is opened in the protective shell 101, and a vibration component 5 is connected to the vibration cavity 1011. The material passing through the protective shell 101 will enter the vibration cavity 1011 and fall on the vibration component 5. The vibration of the vibration component 5 drives the material on its surface to move evenly, thereby realizing the movement of the material. In order to ensure that the vibration component 5 completes the movement of the material, a power component 3 is connected to the vibration component 5. A plurality of vibrators 6 are connected to the vibration component 5. The end of the vibrator 6 away from the vibration component 5 is connected to the cavity wall of the vibration cavity 1011. The vibration component 5 is driven to move by the power component 3, and the direction of vibration is maintained by the vibrator 6, thereby ensuring the normal movement of the material on the surface of the vibration component 5.

[0022] When the bidirectional inertial vibrating feeder is in use, the material to be transported passes through the protective shell 101 and enters the vibration chamber 1011, and falls on the vibration component 5. At this time, the power component 3 and the exciter 6 are controlled to work, driving the vibration component 5 to vibrate, so as to move the material on the vibration component 5. In the process of vibration of the vibration component 5, the connection component 1 will be vibrated, and the vibration frequency of the connection component 1 will be weakened by the vibration reduction component 8 to ensure that the connection component 1 will not shake significantly, thereby ensuring its safety in use.

[0023] In order to ensure the safety of the vibration component 5 when in use and improve the use efficiency of the vibration component 5, two working components 7 for identifying and detecting the conveying status of the vibration component 5 are provided on the vibration component 5. The working components 7 include a connecting plate 701. The two ends of the connecting plate 701 distributed along the length direction are rotatably connected in the vibration cavity 1011. A plurality of connecting columns 702 are connected to one end of the connecting plate 701 close to the vibration component 5. A movable rod 703 is slidably provided at one end of the connecting column 702 away from the connecting plate 701. A resistance rod 7031 is connected to the movable rod 703, and the resistance rod 7031 can resist the vibration component 5.

[0024] Furthermore, the vibration assembly 5 includes a vibration plate 501, wherein the length direction of the connecting plate 701 corresponds to the width direction of the vibration plate 501, the exciters 6 are connected to the vibration plate 501, and the two ends of the vibration plate 501 distributed along the length direction are respectively provided with screening grooves 502 for improving the material transmission efficiency. When the material vibrates on the vibration plate 501 and moves to the area of ​​the screening groove 502, part of the material will directly fall through the screening groove 502, and another part will fall after being transmitted to the end of the screening groove 502 as the vibration of the vibration plate 501, thereby realizing batch conveying of the material, ensuring the material conveying efficiency while effectively reducing the accumulation of the material. The movable rod 703 is located at the screening groove 502, and the movable rod 703 always runs through the screening groove 502.

[0025] Furthermore, the protective shell 101 is respectively penetrated by a feed port 102 and two discharge ports 103, wherein the feed port 102 and the discharge port 103 are respectively located on both sides of the vibration plate 501 along the thickness direction, and the two discharge ports 103 are respectively distributed along the length direction of the protective shell 101, and the material to be transported enters the vibration cavity 1011 through the feed port 102, and as the vibration of the vibration plate 501 is transmitted, the material is moved out of the vibration cavity 1011 through the two discharge ports 103.

[0026] In order to ensure that the material does not separate from the vibration plate 501 during the process of conveying the material, the surface of the vibration plate 501 is further curved, and the distribution of the multiple movable rods 703 is the same as the curvature of the vibration plate 501, that is, the heights of the movable rods 703 passing through each area of ​​the vibration plate 501 are the same.

[0027] In order to ensure that the power component 3 can realize bidirectional vibration feeding to the vibration plate 501, further, the power component 3 includes a first vibration motor 301, the first vibration motor 301 is located on one side of the feed port 102, and the second vibration motor 302 and the third vibration motor 303 are respectively connected between the two discharge ports 103. The first vibration motor 301, the second vibration motor 302 and the third vibration motor 303 can all act on the vibration plate 501. At the same time, the second vibration motor 302 and the third vibration motor 303 have the same rotation direction, and the first vibration motor 301 and the second vibration motor 302 and the third vibration motor 303 have opposite rotation directions. Through the three vibration motors arranged in a herringbone shape, periodic vibration is performed, and the composite vibration is adjusted to realize bidirectional transportation of materials on the vibration plate 501, which has the characteristics of high efficiency and high stability. In this embodiment, the first vibration motor 301, the second vibration motor 302 and the third vibration motor 303 are all prior art and will not be described in detail here.

[0028] Furthermore, a movable groove is provided on one side of the movable rod 703 close to the connecting column 702, and a return spring 704 is connected to one end of the movable rod 703 close to the connecting column 702. The return spring 704 is located in the movable groove, and one end of the return spring 704 away from the movable rod 703 is connected to the connecting column 702. When the resistance rod 7031 is resisted by the vibration plate 501, the movable rod 703 can be compressed according to the pressure on the vibration plate 501, and the return spring 704 can be compressed.

[0029] When the vibration plate 501 is in the process of vibrating and feeding, since the vibration plate 501 and the resistance rod 7031 are in conflict with each other, the movable rod 703 will be in a state of moving at the same frequency as the vibration plate 501, that is, when the vibration plate 501 is in a vibrating state, the return spring 704 can expand and contract with the vibration plate 501, thereby identifying the material condition on the vibration plate 501 and the vibration condition of the vibration plate 501, ensuring that the working state of the vibration plate 501 is always in a stable state.

[0030] When the vibration plate 501 is in a normal working state, the reset spring 704 can be used to identify the weight of the material on the vibration plate 501. When the compression depth of the reset spring 704 is at a normal compression depth, it means that the vibration plate 501 is in a normal working state at this time, and the vibration state of the vibration plate 501 is maintained stable. When the compression depth of the reset spring 704 is deeper, it means that the weight of the material on the vibration plate 501 is heavier, which affects the feeding state of the vibration plate 501. At this time, the vibration frequency of the vibration plate 501 needs to be adjusted.

[0031] When the vibration frequency and compression depth of the reset spring 704 are both in normal state, it means that the vibration of the vibration plate 501 is in normal working state at this time. When the vibration frequency of the reset spring 704 is normal, but the compression depth is deep, it means that the vibration state of the vibration plate 501 is stable at this time, but there is a lot of material stored on the vibration plate 501, which warns the staff to slow down the feeding rate of the feed port 102.

[0032] Furthermore, in order to ensure that the resistance rod 7031 can drive the resistance rod 7031 and the vibration plate 501 to slide relative to each other through the active rotation of the connecting plate 701 during the process of being resisted by the vibration plate 501, the resistance rod 7031 is made cylindrical, and a groove for constraining the position of the resistance rod 7031 is provided on the connecting column 702 to ensure that the movement state of the resistance rod 7031 is stable when the resistance rod 7031 is extended and retracted on the connecting column 702 as the reset spring 704 changes.

[0033] It should be noted that in order to ensure that the return spring 704 can effectively identify the working state of the vibration plate 501, a pressure sensor is arranged at one end of the return spring 704, and the elastic change of the return spring 704 is identified by the change of the pressure indication of the pressure sensor, thereby ensuring that the return spring 704 can identify the working state of the vibration component 5.

[0034] When the device is working, the power assembly 3 is controlled to work, causing the vibration plate 501 to vibrate, and then the vibration exciter 6 is used to maintain the vibration state of the vibration plate 501 stable, thereby ensuring that the vibration plate 501 is in a normal vibration state.

[0035] The material to be transported enters the vibration chamber 1011 through the feed port 102 and falls on the vibration assembly 5, thereby realizing the transportation and separation of the material. Specifically, when the material falls on the vibration plate 501, the vibration of the vibration plate 501 is used to move the material to the side close to the screening slot 502, so that the material moves through the screening slot 502 to the discharge port 103, thereby realizing the replenishment of the material.

[0036] When the vibration plate 501 is in a normal working state, the movable rod 703 vibrates with the vibration frequency of the vibration plate 501, and when the material passes through the screening slot 502, part of the material will pass through the screening slot 502 and directly fall to the discharge port 103, and the remaining material will move to the end of the vibration plate 501 after passing through the movable rod 703 with the vibration of the vibration plate 501, and then enter the discharge port 103. In the process of moving to the end, the material continues to pass through the screening slot 502 to separate from the vibration plate 501, and in order to ensure the stability of the feeding rate of the vibrating feeder during feeding, the movable rod 703 is used to adjust the material replenishment rate on the vibration plate 501, that is, when the material passes through the movable rod 703, the excess material can be blocked by the movable rod 703 or the material can be accelerated to pass through the screening slot 502, thereby ensuring the stability of the discharge rate through the discharge port 103.

[0037] In order to judge the working state of the vibration component 5, during use, the state of the vibration component 5 is identified by identifying the working state of the reset spring 704. When the reset spring 704 is at a normal compression depth and the compression frequency is in a normal state, it means that the vibration plate 501 is in a normal working state at this time, and the power component 3 and the exciter 6 are in a stable working mode, ensuring that the discharge port 103 is in a normal feeding progress.

[0038] When the reset spring 704 is at a normal compression depth but its compression frequency is in an abnormal state, it means that the feed rate on the vibration plate 501 is stable and in a normal state, but the power component 3 and the exciter 6 have malfunctions, which affect the vibration amplitude of the vibration plate 501, thereby interfering with the material replenishment rate, causing the pressure sensor on the reset spring 704 to show an abnormal reading, prompting the staff to test the working performance of the power component 3 and the exciter 6 to ensure that the bidirectional inertial vibrator is in a normal conveying state.

[0039] When the return spring 704 is at a normal compression frequency but the compression depth increases, it means that the periodic expansion and contraction changes of the return spring 704 are in a normal state, indicating that the working conditions of the power component 3 and the vibrator 6 are stable, and can ensure that the vibration plate 501 vibrates and conveys the material above it. However, due to the increase in the compression depth of the return spring 704, when ensuring that the vibration component 5 is in a normal working state, it means that the amount of material falling onto the vibration plate 501 through the feed port 102 increases, causing the gravity on the vibration plate 501 to increase.

[0040] When the compression depth of the reset spring 704 increases and remains constant, the vibration amplitude of the power component 3 and the vibrator 6 is increased according to the pressure indication of the pressure sensor, and the vibration amplitude of the vibration plate 501 is increased to ensure that the material on the vibration plate 501 can be stably transported; when the compression depth of the reset spring 704 is in a gradually deepening stage, the vibration amplitude of the power component 3 and the vibrator 6 is initially regulated. When the reset spring 704 is continuously compressed, the operation of the power component 3 and the vibrator 6 is interrupted, the vibration plate 501 is prompted to stop vibrating, and the staff is prompted to inspect the feed port 102. On the one hand, the feeding rate is ensured to be stable, and on the other hand, excessive pressure on the vibration plate 501 is avoided to damage the power component 3 and the vibrator 6, thereby ensuring the constant service life of the vibrating feeder.

[0041] After inspection by the staff, when the feed port 102, the power assembly 3 and the exciter 6 are all in normal working mode, but the compression amplitude of the reset spring 704 and the indication of the pressure sensor continue to increase, it means that the screening slot 502 is blocked by materials. At this time, while maintaining the normal operation of the power assembly 3 and the exciter 6, the connecting plate 701 is controlled to rotate in the vibration chamber 1011 to realize the rotation of the connecting column 702 and the movable rod 703. Since the interference rod 7031 is cylindrical and always conflicts with the vibration plate 501, during the rotation of the connecting plate 701, the elastic effect of the reset spring 704 will promote The length of the connecting column 702 and the movable rod 703 is extended so that the movable rod 703 can move in the screening slot 502, so as to clear the blockage in the screening slot 502. When a blockage appears in the screening slot 502, the elastic action of the power assembly 3, the vibrator 6 and the return spring 704 is utilized to clear the impurities in the screening slot 502, that is, the vibration plate 501 drives the resistance rod 7031 to move when it vibrates, so that the contact pressure between the movable rod 703 and the impurities in the screening slot 502 is always in a dynamically changing process, thereby clearing the blockage in the screening slot 502 and ensuring that the vibration plate 501 maintains a normal conveying state. Embodiment 2

[0042] A method for using a bidirectional inertial vibrating feeder comprises the following steps: S1, control the power assembly 3 and the exciter 6 to work, drive the vibration plate 501 to vibrate, and thus drive the movable rod 703 to vibrate; S2, conveying the material to be conveyed into the vibration chamber 1011 through the feed port 102, so that the material falls onto the vibration plate 501, and the material is conveyed as the vibration plate 501 vibrates; S3, when the material is transported to one side of the screening slot 502 on the vibration plate 501, the material falls from the vibration plate 501 in sequence through the screening slot 502; S4, using the movable rod 703 to comb the material passing through the screening slot 502 to ensure stable material transportation through the screening slot 502, and at the same time using the movable rod 703 to identify the working state of the return spring 704 during the vibration process, so as to ensure the stable vibration state of the vibration plate 501; S5. The material after passing through the screening slot 502 is discharged from the vibration chamber 1011 through the discharge port 103 in sequence, completing the feeding of the material.
