[0015] The beneficial effects of this utility model are as follows: This utility model provides a steel sleeve vibration screening device, which has the following beneficial effects.

[0016] (1) Steel sleeves of different specifications to be screened are poured into a vibrating plate. The vibration of the vibrating plate causes the steel sleeves inside to spirally rise along the vibrating track to the discharge port. During the ascent, the steel sleeves gradually arrange themselves into a single row, and then, under the action of the guide plate at the discharge port, they enter the screening channel in sequence. The steel sleeves in the screening channel move forward along the screening channel under the action of vibration. Qualified steel sleeves will continue to move forward along the screening channel through the screening area below the fixed plate. Unqualified steel sleeves cannot pass through the screening area and will fall directly into the receiving box along the unqualified channel for unified collection. Steel sleeves that continue to move forward through the screening area will be... The steel sleeves pass through a guiding device and a flipping device. The guiding device guides all the steel sleeves into a forward-facing arrangement. After passing through the flipping device, the steel sleeves are flipped into an inverted reverse state. The flipped steel sleeves help the vibratory feeder to more accurately identify steel sleeves of different specifications, thereby transporting them to the correct steel sleeve sorting channel. This realizes the automation of steel sleeve screening, greatly improves screening efficiency, enhances the accuracy of screening different steel sleeves, avoids confusion, and ensures the compatibility of subsequent automotive parts. At the same time, it replaces the traditional manual screening method, reduces the workload of workers, and saves labor costs.

[0017] (2) The setting of the limiting device can further limit the size of the steel sleeve, prevent the vibration plate from making mistakes in identification, and prevent confusion between steel sleeves, thereby further enhancing the accuracy of steel sleeve screening.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0025] Example 1:

[0026] like Figures 1-5 As shown, this utility model provides a steel sleeve vibration screening device, including a vibrating plate 1, a screening channel 2, and a sorting channel. The vibrating plate 1 is connected to the screening channel 2. The screening channel 2 is fixedly installed on the outside of the vibrating plate 1 and arranged to rotate along the outside of the vibrating plate 1. Multiple sorting channels are connected to the screening channel 2. The sorting channels are used to sort steel sleeves 3 of different specifications. A spiral rising vibration track 4 is installed inside the vibrating plate 1. The discharge port at the uppermost end of the vibration track 4 is connected to the screening channel 2.

[0027] Furthermore, a guide plate 5 is installed at the connection between the discharge port and the screening channel 2. The guide plate 5 includes a first guide plate 51, a second guide plate 52, and a third guide plate 53. The first guide plate 51 is fixedly installed at the top position outside the vibrating plate 1 at the discharge port. The second guide plate 52 is fixedly connected to the discharge port of the vibrating plate 1 and is inclined towards the screening channel 2. The third guide plate 53 is fixedly installed at the end of the second guide plate 52 away from the discharge port. The third guide plate 53 is inclined from the inside to the outside along the screening direction.

[0028] The steel sleeve 3 inside the vibratory feeder 1, under the action of the first guide plate 51, enters the second guide plate 52 and moves along the second guide plate 52. Since the second guide plate 52 is arranged at a downward angle, the steel sleeve 3 slides downward along the second guide plate 52. The outer side plate 24 of the screening channel 2 limits the sliding steel sleeve 3, causing the steel sleeve 3 to re-enter the screening channel 2 in either the forward or reverse direction under the action of the third guide plate 53. The principle is that the steel sleeve 3 moves along the vibrating track 4 under the action of vibration. The vibrating track 4 transforms the stacked steel sleeves 3 into a single row during the spiral ascent, so that the steel sleeves 3 reaching the discharge port of the vibratory feeder 1 are in three states: forward, reverse, and lying down. The steel sleeve 3 consists of a ring 31 and a column 32. The ring 31 is fixedly installed on the column 32. The forward state of the steel sleeve 3 is as follows... Figure 4 As shown, with the ring 31 on top and the column 32 on the bottom, the reverse state of the steel sleeve 3 is as follows: Figure 5 As shown, with the column 32 on top and the ring 31 on the bottom, the width between the outer side plate 24 of the screening channel 2 and the outer side of the guide plate 2 52 is greater than the diameter of the bottom column 32 of the steel sleeve 3 and less than the diameter of the top ring 31 of the steel sleeve 3. The width between the outer side of the guide plate 2 52 behind the guide plate 3 53 and the outer side plate 24 of the screening channel 2 is greater than the diameter of the top of the steel sleeve 3. When the steel sleeve 3, which is in a lying position, passes the inclined guide plate 2 52, and under the blocking effect of the outer side plate 24 of the screening channel 2, the lying steel sleeve 3 changes to a forward and reverse state, enters the screening channel 2 along the guide plate 3 53, and continues to move forward along the screening channel 2.

[0029] If a small number of steel sleeves 3, lying down, still enter the screening channel 2 after passing through the second guide plate 52 and the third guide plate 53, they will roll down into the collection trough 25 below the screening channel 2 during the vibration screening process. The collection trough 25 is fixedly installed on the outside of the vibrating plate 1 and is arranged at an angle downward along the screening direction. This allows the steel sleeves 3 that have entered the collection trough 25 to fall into the bottom of the collection trough 25 along the angle of the collection trough 25. The screening channel 2 has a notch 26 at the bottom of the collection trough 25. The operator can take out the steel sleeves 3 from the collection trough 25 through the notch 26 and then pour them back into the vibrating plate 1.

[0030] Furthermore, the sorting channel includes a defective channel 6 and multiple steel sleeve sorting channels 7. The multiple steel sleeve sorting channels 7 are located behind the defective channel 6. The screening channel 2 is first connected to the defective channel 6. The defective steel sleeves 3 enter the receiving box 8 along the defective channel 6. Specifically, in this embodiment, there are four steel sleeve sorting channels 7, which are used to sort four similar steel sleeves of different specifications 3.

[0031] Furthermore, a fixing plate 9 is fixedly installed on the top of the screening channel 2, and the fixing plate 9 and the bottom of the screening channel 2 form a screening area. The qualified steel sleeves 3 pass through the screening area and enter different steel sleeve sorting channels 7 along the screening channel 2.

[0032] The steel sleeves 3, which pass through the guide plate 5 and enter the screening channel 2 in either the forward or reverse direction, will pass through the fixing plate 9 as they move forward along the screening channel 2. Qualified steel sleeves 3 will pass through the screening area in sequence and enter the subsequent screening channel 2 to continue moving forward, and then fall into different steel sleeve sorting channels 7. Unqualified steel sleeves 3 will be blocked by the fixing plate 9 and enter the receiving box 8 along the direction of the fixing plate 9 and the unqualified channel 6. When a certain number of unqualified steel sleeves 3 are collected in the receiving box 8, the receiving box 8 is picked up and the steel sleeves 3 in it are poured into the designated position.

[0033] Furthermore, the screening channel 2 is provided with a guiding device and a flipping device. The guiding device is located behind the fixed plate 9, and the flipping device is located behind the guiding device. The guiding device is used to guide the qualified steel sleeves 3, so that the steel sleeves 3 arranged in the forward or reverse direction on the screening channel 2 are uniformly turned into the forward state. The flipping device is used to flip the qualified steel sleeves 3 in the forward state to the reverse state.

[0034] The purpose of flipping the steel sleeves 3 from the forward position to the reverse position is not only to enhance the stability of the vibration screening process of the steel sleeves 3, but also to make it easier for the vibrating plate 1 to transport the steel sleeves 3 with different shapes, sizes or weights to the correct steel sleeve sorting channel 7, thus ensuring the accuracy of the screening.

[0035] Furthermore, the guiding device includes guide rod 10, guide rod 11, guide rod 12, guide plate 13, guide plate 14, and guide plate 15. One end of guide plate 13 is fixedly connected to the bottom of the screening channel 2 near the middle, thus narrowing the screening channel 2. The other end is fixedly connected to the outside of the vibrating plate 1. One end of guide rod 10 is fixedly installed on the outside of the vibrating plate 1 or on the bottom of the screening channel 2. If guide rod 10 is fixedly installed on the bottom of the screening channel 2, it is located inside guide plate 13, i.e., on the side closer to the vibrating plate 1. The other end of guide rod 10 extends outward to above guide plate 14. One end of the second guide rod 11 is fixedly connected to the lower part of the outer side of the screening channel 2, and the other end is fixedly connected to one end of the second guide plate 14 and the third guide plate 15. The second guide plate 14 and the third guide plate 15 intersect at the second guide rod 11. The other ends of the second guide plate 14 and the third guide plate 15 extend outward, forming a triangular outwardly widening guide channel 16 together with the bottom plate 27. The guide channel 16 is part of the screening channel 2. The qualified steel sleeve 3 enters the flipping device through the guide channel 16. One end of the third guide rod 12 is fixedly connected to the top of the outer side plate 24 of the screening channel 2, and the other end is located above the third guide plate 15.

[0036] The qualified steel sleeve 3 passing through the screening area below the fixed plate 9 continues to advance along the screening channel 2. Under the action of the guide plate 13 and the guide rod 10, the screening channel 2 tightens inward. The ring 31 of the steel sleeve 3 in the reverse state moves along the area between the guide rod 10 and the guide rod 11, causing the steel sleeve 3 to tilt slightly. Since the height of the end of the guide rod 10 away from the screening channel 2 is higher than the height of the end near the screening channel 2, and the end away from the screening channel 2 will also expand outward, so that it is above the guide plate 14, the ring 31 of the steel sleeve 3, which was initially tilted slightly, gradually becomes vertical. After being guided by the guide rod 11, the ring 31 enters the gap between the guide plate 13 and the guide plate 14, and then enters the guide channel 16 along the gap. At this time, after the guiding effect of the guide rod 10 disappears, the tilted steel sleeve 3 flips downward under the gravity of its own column 32, so that it is placed upright on the guide channel 16.

[0037] The ring 31 of the steel sleeve 3 in the forward state will move along the area between the guide rod 3 12 and the guide rod 2 11, and then continue to move along the area between the guide rod 3 12 and the guide plate 3 15, so that the ring 31 changes from a horizontal to a vertical arrangement. After the guiding effect of the guide rod 3 12 disappears, the inclined steel sleeve 3 flips downward under the gravity of its own column 32, so that it is placed in the forward position on the guide channel 16. Thus, the steel sleeve 3 that has passed through the guide device in either the forward or reverse direction can be placed in the forward position. All the steel sleeves 3 placed in the forward position continue to move forward along the screening channel 2.

[0038] Furthermore, the flipping device includes a first flipping rod 17, a second flipping rod 18, a flipping plate 19, and an extension plate 28. One end of the flipping plate 19 is fixedly connected to the bottom middle position of the guide channel 16. The top surface of the flipping plate 19 and the top surface of the guide channel 16 are on the same plane. The other end of the flipping plate 19 is fixedly connected to the inner side of the screening channel 2. One end of the first flipping rod 17 is fixedly installed on the inner side of the guide channel 16, and the other end extends above the flipping plate 19. One end of the second flipping rod 18 is fixedly connected to the outer side of the guide channel 16, and the other end is fixedly connected to the flipping plate 19 on the screening channel 2. The extension plate 28 is fixedly connected to the outer side of the guide channel 16, and the other end is fixedly connected to the outer side of the subsequent screening channel 2.

[0039] The steel sleeve 3 in the guide channel 16 is in the forward state. The column 32 of the steel sleeve 3 will move forward along the flipping rod 17 and flipping rod 28, so that the ring 31 of the steel sleeve 3 gradually changes from horizontal to vertical arrangement. Since the other end of the flipping rod 28 is fixedly connected to the flipping plate 19, the movement of the steel sleeve 3 will be cut off. The ring 31 flips downward under the action of gravity and falls onto the extension plate 28. Then it is placed in the opposite direction on the screening channel 2 along the extension plate 28. As the screening channel 2 continues to move forward, it falls into different steel sleeve sorting channels 7.

[0040] Furthermore, a photoelectric sensor is installed at the entrance of each of the steel sleeve sorting channels 7. The photoelectric sensor is electrically connected to the control system of the vibrating plate 1. The photoelectric sensor can accurately identify the diameter of the corresponding steel sleeve 3 and then transmit it to the control system. The control system will screen and classify different steel sleeves 3 according to preset parameters and logic.

[0041] Furthermore, a receiving basket is placed at the bottom of each of the steel sleeve sorting channels 7. The receiving basket is used to receive the sorted steel sleeves 3. A counting sensor is installed on each of the steel sleeve sorting channels 7. The counting sensor is used to count the number of steel sleeves 3 sorted by the steel sleeve sorting channel 7.

[0042] Furthermore, the vibrating tracks 4 inside the vibrating plate 1 are connected by a feed inlet 29, which is located at the bottom of the vibrating plate 1. The steel sleeves 3 enter the vibrating plate 1 through the feed inlet 29 for screening. When the number of steel sleeves 3 is small, they can also be poured in manually.

[0043] The working principle of this embodiment is as follows:

[0044] Steel sleeves 3 of different specifications enter the vibratory feeder 1 through the feed inlet 29. Under the action of vibration, they spiral upward along the vibratory track 4 and form a single row. Then, they enter the screening channel 2 through the discharge outlet along the direction of the guide plate 5 in either the forward or reverse direction. As they advance along the screening channel 2, qualified steel sleeves 3 that meet the screening requirements will smoothly pass through the screening area below the fixed plate 9 and continue to advance. Steel sleeves that do not meet the requirements will enter the receiving box 8 along the unqualified channel 6. The steel sleeves 3 that continue to advance will first pass through the guiding device, which will guide all steel sleeves 3 in the forward or reverse state to the forward state. The steel sleeves 3 in the forward state will continue to pass through the flipping device. After being flipped by the flipping device, all steel sleeves 3 in the forward state will be flipped to the reverse state. As the steel sleeves 3 in the reverse state continue to advance along the screening channel 2, the photoelectric sensor can identify the size and other information of the steel sleeves 3 that pass by at any time and transmit this information to the control system. The control system will screen and classify different steel sleeves 3 according to preset parameters and logic, so that they enter the corresponding receiving basket along the corresponding steel sleeve sorting channel 7.

[0045] Example 2:

[0046] like Figure 1 and Figure 2 As shown, based on Embodiment 1, this utility model provides a steel sleeve vibration screening device, wherein a limiting device is installed at the entrance of each steel sleeve sorting channel 7, and the limiting device is used to screen steel sleeves 3 of different specifications.

[0047] Furthermore, the limiting device includes a limiting plate 20, one end of which is fixedly installed at the entrance, and the other end of which forms a passage area 21 with the entrance. The passage area 21 is adapted to the annular area of ​​the steel sleeve 3. The passage areas 21 of different widths are used to pass through steel sleeves 3 of different specifications. The width of the passage area 21 gradually increases along the screening direction, that is, the steel sleeves 3 with relatively small size are screened first to prevent the steel sleeve sorting channel 7 that collects large-sized steel sleeves 3 from mixing with small-sized steel sleeves 3, which would lead to inaccurate screening results.

[0048] The control system adjusts the corresponding vibration force and vibration frequency parameters according to the preset parameters and logic to screen and classify different steel sleeves 3. The steel sleeves 3 of the appropriate specifications pass through the passage area 21 along the limit plate 20 and enter the corresponding steel sleeve sorting channel 7, which plays a further restrictive role and prevents the photoelectric sensor from malfunctioning and causing confusion between steel sleeves 3.

[0049] Example 3:

[0050] like Figure 1 and Figure 2 As shown, based on the above embodiments, this utility model provides a steel sleeve vibration screening device. The limiting device includes a second limiting plate 22. The two ends of the second limiting plate 22 are fixedly installed at the entrance. A rectangular limiting hole 23 is opened on the second limiting plate 22. The limiting hole 23 is used to limit the height and width of the steel sleeve 3 passing through.

[0051] Limiting plate 1 20 and limiting plate 22 can be used on different vibratory feeders 1, or they can be used on the same type of vibratory feeder 1 at the same time, depending on actual needs.

[0052] In the description of this utility model, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inner", "outer", "back", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0053] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
