[0024] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercial products unless otherwise specified.

[0025] Embodiment 1:

[0026] like Figure 1 to Figure 5 As shown, the present invention provides a steel sleeve vibration screening device, including a vibration disk 1, a screening channel 2 and a sorting channel, the vibration disk 1 is connected to the screening channel 2, the screening channel 2 is fixedly installed on the outside of the vibration disk 1 and spirally arranged along the outside of the vibration disk 1, the screening channel 2 is connected with a plurality of the sorting channels, the sorting channels are used to sort steel sleeves 3 of different specifications, a spiral ascending vibration track 4 is installed in the vibration disk 1, and the uppermost discharge port 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, and the guide plate 5 includes a guide plate 1 51, a guide plate 2 52 and a guide plate 3 53. The guide plate 1 51 is fixedly installed at the top position of the outer side of the vibration plate 1 at the discharge port, the guide plate 2 52 is fixedly connected to the discharge port of the vibration plate 1, and is arranged obliquely toward the screening channel 2, and the guide plate 3 53 is fixedly installed at one end of the guide plate 2 52 away from the discharge port, and the guide plate 3 53 is arranged obliquely from the inside to the outside along the screening direction.

[0028] The steel sleeve 3 in the vibration plate 1 enters the guide plate 2 52 and moves along the guide plate 2 52 under the action of the guide plate 1 51. Since the guide plate 2 52 is arranged to be tilted downward, the steel sleeve 3 slides downward along the guide plate 2 52. The outer plate 24 of the screening channel 2 limits the sliding steel sleeve 3, so that the steel sleeve 3 enters the screening channel 2 in the forward or reverse direction under the action of the guide plate 3 53. The principle is that the steel sleeve 3 moves along the vibration track 4 under the action of the vibration force. The vibration track 4 arranges the stacked steel sleeves 3 in a single row during the spiral ascent, so that the steel sleeve 3 arriving at the discharge port of the vibration plate 1 presents three states, namely, forward, reverse and lying down. The steel sleeve 3 is composed of a ring body 31 and a column body 32. The ring body 31 is fixedly mounted on the column body 32. The forward state of the steel sleeve 3 is as follows: Figure 4 As shown, the ring body 31 is on the top and the column 32 is on the bottom. The reverse state of the steel sleeve 3 is as shown in FIG. Figure 5 As shown, that is, the column 32 is on the top and the ring body 31 is on the bottom. Since the width between the outer plate 24 of the screening channel 2 and the outer side of the guide plate 2 52 is larger than the diameter of the bottom column 32 of the steel sleeve 3, and smaller than the diameter of the ring body 31 at the top 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 larger than the diameter of the top of the steel sleeve 3. When the steel sleeve 3 in a lying state passes through the inclined guide plate 2 52 and under the blocking effect of the outer side plate 24 of the screening channel 2, the steel sleeve 3 in the lying state changes to a forward and reverse state, enters the screening channel 2 along the guide plate 3 53, and continues to move along the screening channel 2.

[0029] If there is still a small amount of lying steel sleeves 3 entering the screening channel 2 after passing through the guide plate 2 52 and the guide plate 3 53, at this time, the lying steel sleeves 3 will roll into the collecting trough 25 below the screening channel 2 during the vibration screening along the screening channel 2. The collecting trough 25 is fixedly installed on the outer side of the vibration plate 1. The collecting trough 25 is arranged to be tilted downward along the screening direction, so that the steel sleeves 3 entering the collecting trough 25 fall to the bottom of the collecting trough 25 along the tilted direction of the collecting trough 25. The screening channel 2 is provided with a notch 26 at the bottom position of the collecting trough 25, and the operator can take out the steel sleeve 3 in the collecting trough 25 from the notch 26, and then pour it into the vibration plate 1 again.

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

[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 forward or reverse steel sleeves 3 that enter the screening channel 2 through the guide plate 5 will pass through the fixed plate 9 while moving along the screening channel 2. The qualified steel sleeves 3 will pass through the screening area in turn and enter the subsequent screening channel 2 to continue moving forward, and then fall into different steel sleeve sorting channels 7. The unqualified steel sleeves 3 will be stopped by the fixed plate 9 and enter the receiving box 8 along the unqualified channel 6 along the direction of the fixed plate 9. When a certain number of unqualified steel sleeves 3 are collected in the receiving box 8, the receiving box 8 will be picked up and the steel sleeves 3 therein will be poured to the designated position.

[0033] Furthermore, a guiding device and a flipping device are provided on the screening channel 2. The guiding device is located on the rear side of the fixing plate 9, and the flipping device is located on the rear side of 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 changed into the forward state, and the flipping device is used to flip the qualified steel sleeves 3 in the forward state to the reverse state.

[0034] The steel sleeves 3 in the forward state are uniformly flipped to the reverse state. The main purpose is not only to enhance the stability of the vibration screening process of the steel sleeves 3, but also to make the vibration plate 1 more easily detect the differences in shape, size or weight of different steel sleeves 3, and transport them to the correct steel sleeve sorting channel 7 to ensure the accuracy of screening.

[0035] Furthermore, the guide device includes a guide rod 10, a guide rod 2 11, a guide rod 3 12, a guide plate 13, a guide plate 2 14 and a guide plate 3 15. One end of the guide plate 13 is fixedly connected to the bottom of the screening channel 2 near the middle position, so that the screening channel 2 becomes narrower, and the other end is fixedly connected to the outer side of the vibration plate 1. One end of the guide rod 10 is fixedly installed on the outer side of the vibration plate 1 or fixedly installed on the bottom of the screening channel 2. If the guide rod 10 is fixedly installed on the bottom of the screening channel 2, it is located on the inner side of the guide plate 13, that is, on the side close to the vibration plate 1. The other end of the guide rod 10 extends outward to the top of the guide plate 2 14. One end of the guide rod 2 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 guide plate 2 14 and the guide plate 3 15. The guide plate 2 14 and the guide plate 3 15 form an intersection at the guide rod 2 11. The other ends of the guide plate 2 14 and the guide plate 3 15 extend outward and together with the bottom plate 27 form a triangular guide channel 16 that widens outward. The guide channel 16 is a part of the screening channel 2. The qualified steel sleeve 3 enters the flipping device through the guide channel 16. One end of the guide rod 3 12 is fixedly connected to the top of the outer plate 24 of the screening channel 2, and the other end is located above the guide plate 3 15.

[0036] The qualified steel sleeve 3 passing through the screening area below the fixed plate 9 continues to move along the screening channel 2. Under the action of the guide plate 13 and the guide rod 10, the screening channel 2 is tightened inward, and the ring body 31 of the steel sleeve 3 in the reverse state will move along the area between the guide rod 10 and the guide rod 2 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 close to the end of 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 2 14, the ring body 31 of the steel sleeve 3, which is initially slightly tilted, is gradually arranged vertically. After being guided by the guide rod 2 11, the ring body 31 enters the gap between the guide plate 13 and the guide plate 2 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 action of the gravity of its own column 32, so that it is placed forward on the guide channel 16.

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

[0038] Furthermore, the flipping device includes a flip rod 17, a flip rod 18, a flip plate 19 and an extension plate 28, one end of the flip plate 19 is fixedly connected to the bottom middle position of the guide channel 16, the top surface of the flip plate 19 and the top surface of the guide channel 16 are located on the same plane, the other end of the flip plate 19 is fixedly connected to the inner side of the screening channel 2, one end of the flip rod 17 is fixedly installed on the inner side of the guide channel 16, and the other end extends to the top of the flip plate 19, one end of the flip rod 18 is fixedly connected to the outer side of the guide channel 16, and the other end is fixedly connected to the flip 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 is in the forward state in the guide channel 16, and the column 32 of the steel sleeve 3 will move forward along the flip rod 17 and the flip rod 2 18, so that the ring body 31 of the steel sleeve 3 gradually changes from a horizontal arrangement to a vertical arrangement. Since the other end of the flip rod 2 18 is fixedly connected to the flip plate 19, the movement of the steel sleeve 3 will be cut off, and the ring body 31 will flip downward under the action of gravity and fall onto the extension plate 28, and then be placed on the screening channel 2 in the opposite direction along the extension plate 28, and as the screening channel 2 continues to move forward, it will fall 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, and the photoelectric sensor is electrically connected to the control system of the vibration disk 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, and 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, and the counting sensor is used to count the number of steel sleeves 3 sorted by the steel sleeve sorting channel 7.

[0042] Furthermore, a feed port 29 is opened between the vibration tracks 4 in the vibration disk 1, and the feed port 29 is located at the lower part of the vibration disk 1. The steel sleeves 3 enter the vibration disk 1 from the feed port 29 for screening. When the number of steel sleeves 3 is small, they can also be poured directly by hand.

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

[0044] Steel sleeves 3 of different specifications enter the interior of the vibration disk 1 from the feed port 29, and under the action of the vibration force, they spirally rise along the vibration track 4 and form a single row arrangement, and then enter the screening channel 2 in a forward or reverse state through the discharge port along the direction of the guide plate 5, and move forward along the screening channel 2. Qualified steel sleeves 3 that meet the current screening requirements will smoothly pass through the screening area under the fixed plate 9 and continue to move forward, and 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 move forward will first pass through the guide device, and all the steel sleeves 3 that are in the forward or reverse state at this time will be guided to the forward state. The steel sleeves 3 in the forward state will continue to pass through the flipping device. After flipping by the flipping device, all the steel sleeves 3 in the forward state are flipped to the reverse state. In the process of the steel sleeves 3 in the reverse state continuing to be screened and moved forward along the screening channel 2, the photoelectric sensor can identify the size and other information of the passing steel sleeves 3 at any time, and transmit the information to the control system. The control system will screen and classify different steel sleeves 3 according to the preset parameters and logic, so that they enter the corresponding receiving basket along the corresponding steel sleeve sorting channel 7.

[0045] Embodiment 2:

[0046] like Figure 1 and Figure 2 As shown, based on Example 1, the present invention provides a steel sleeve vibration screening device, and a limiting device is installed at the entrance of each steel sleeve sorting channel 7, and the limiting device is used to screen the 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 the limiting plate 20 forms a passing area 21 with the entrance, and the passing area 21 is adapted to the annular area of ​​the steel sleeve 3. The passing areas 21 of different widths are used to pass the steel sleeves 3 of different specifications. The width of the passing area 21 gradually increases along the screening direction, that is, the steel sleeves 3 with relatively small sizes are screened first to prevent the steel sleeve sorting channel 7 that collects large-sized steel sleeves 3 from mixing into small-sized steel sleeves 3, resulting in inaccurate screening results.

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

[0049] Embodiment 3:

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

[0051] The limiting plate 1 20 and the limiting plate 2 22 can be used on different vibration plates 1 respectively, or can be used on the same vibration plate 1 at the same time according to actual needs.

[0052] In the description of the present invention, it is necessary to understand that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inside", "outside", "back", "middle", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0053] However, what is described above is only a specific embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the present invention should still fall within the scope covered by the claims of the present invention.
