Abstract
Description
Technical Field
[0001] This utility model relates to the field of screening equipment technology, and in particular to a screening device. Background Technology
[0002] In machining, measuring blocks are typically used to compare worn cutting tools with their lengths to screen out tools that are longer than a preset value. This allows qualified tools to be machined and repaired for reuse, thus reducing operating costs. However, measuring large quantities of worn tools is labor-intensive and reduces screening efficiency. Utility Model Content
[0003] In view of the above situation, it is necessary to provide a screening device to improve screening efficiency.
[0004] This application provides a screening device, including: A feeding assembly includes a feeding component, a rotating component, and a driving component. The feeding component has a receiving groove configured to receive multiple stacked workpieces. The rotating component is movably inserted through the feeding component and extends into the receiving groove. The rotating component has a receiving groove and a supporting arc surface. The receiving groove and the supporting arc surface are sequentially arranged on the side wall of the rotating component along the rotation direction of the rotating component. The receiving groove is configured to receive the workpiece located at the bottom layer of the multiple workpieces. The driving component is connected to the rotating component and is used to drive the rotating component to move the bottom layer workpiece out of the receiving groove and to make the supporting arc surface abut against the workpiece adjacent to the bottom layer workpiece. A guiding assembly, disposed on one side of the feeding component and having a guiding groove, the guiding groove communicating with the receiving groove; and A screening component, connected to the guide component, is provided with an inclined surface and a screening groove. The inclined surface is inclined in a first direction relative to the rotating member and in a second direction relative to the rotating member. The inclined surface is provided with a receiving position and a discharging position. The receiving position is located adjacent to the guide component relative to the discharging position. The inclined surface is configured to receive the workpiece guided to the receiving position via the guide groove and guide the workpiece to move from the receiving position toward the discharging position. The screening groove is located between the receiving position and the discharging position and extends through the screening component in a third direction. The screening groove has a preset length so that workpieces less than or equal to the preset length fall into the screening groove. The first direction, the second direction, and the third direction are perpendicular to each other.
[0005] In operation, the aforementioned screening device first provides multiple stacked workpieces. A rotating component receives the bottom workpiece from the stack via a receiving groove. Then, a driving component rotates the rotating component, moving the bottom workpiece from the receiving groove to a guide groove. The workpiece then moves to the receiving position on the inclined surface via the guide groove. Simultaneously, the rotating component's abutting arc surface abuts against the workpiece adjacent to the bottom workpiece, preventing other workpieces from entering the guide groove and ensuring that only a single workpiece is transferred out of the receiving groove. Finally, the inclined surface guides the workpieces from the receiving position towards the discharge position, allowing workpieces of a preset length or less to enter the screening groove and workpieces longer than the preset length to be discharged. Thus, the screening device continuously provides workpieces to the inclined surface through the feeding and guiding components, and uses the combination of the inclined surface and the screening groove to screen workpieces longer than the preset length, achieving rapid and accurate workpiece screening and improving screening efficiency.

[0007] In some embodiments, the filtering component further includes: A limiting member is provided at one end of the inclined surface away from the guide assembly and connected to the screening member. The limiting member is used to abut against and limit the workpiece to the inclined surface.
[0008] In some embodiments, the filtering component further includes: A detection element is disposed near the screening slot and connected to the screening element. The detection element is electrically connected to the drive element and is configured to detect the number of the screened and qualified workpieces.
[0009] In some embodiments, the filtering component further includes: A holding member is disposed at the receiving position and located above the inclined surface.

The sliding groove is inclined relative to the guide groove and communicates with the guide groove. The sliding groove is configured to guide the workpiece to slide from the guide groove to the inclined surface.
[0012] In some embodiments, the cross-section of the guide groove in the second direction decreases along the direction from the feeder toward the guide assembly.
[0013] In some embodiments, the feeder includes: A feed body is disposed on one side of the guide assembly and is provided with the receiving groove. The feed body is configured to receive the workpiece. A cover plate is placed over the storage slot and is detachably connected to the feeding body.

[0023] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.
[0024] Please see Figure 1 This application provides a screening device 100, which includes a feeding assembly 10, a guiding assembly 20, and a screening assembly 30. The screening device 100 is used to screen workpieces 200 that are longer than a preset length. The workpiece 200 can be a cutting tool, a round bar, etc.
[0025] To facilitate understanding and explanation of the embodiments of this application, a three-dimensional coordinate system has been established in some of the accompanying drawings, with the first direction being... Figure 1 The X-axis direction is shown, and the second direction is... Figure 1 The Y-axis direction shown is the third direction. Figure 1 The Z-axis direction shown is perpendicular to each other in the first, second, and third directions.
[0026] Please see Figure 1 , Figure 2 , Figure 3and Figure 4 The feeding assembly 10 includes a feeding component 11, a rotating component 12, and a driving component 13. The feeding component 11 has a receiving groove 111, which is configured to receive a plurality of stacked workpieces 200. The rotating component 12 is movably inserted through the feeding component 11 and extends into the receiving groove 111. The rotating component 12 has a receiving groove 121 and a supporting arc surface 122, which are sequentially arranged on the side wall of the rotating component 12 along the rotation direction of the rotating component 12. The receiving groove 121 is configured to receive the bottommost workpiece 200 among the plurality of workpieces 200. The driving component 13 is connected to the rotating component 12 and is used to drive the bottommost workpiece 200 of the rotating component 12 to move out of the receiving groove 111 and to make the supporting arc surface 122 abut against the workpiece 200 adjacent to the bottommost workpiece 200. A guide assembly 20 is located on one side of the feeder 11 and has a guide groove 21, which communicates with the receiving groove 111. A screening assembly 30 is connected to the guide assembly 20. The screening assembly 30 has an inclined surface 31 and a screening groove 32. The inclined surface 31 is inclined relative to the rotating member 12 in a first direction and in a second direction. The inclined surface 31 has a receiving position 311 and a discharging position 312. The receiving position 311 is located adjacent to the guide assembly 20 relative to the discharging position 312. The inclined surface 31 is configured to receive the workpiece 200 guided by the guide groove 21 to the receiving position 311 and guide the workpiece 200 to move from the receiving position 311 toward the discharging position 312. The screening groove 32 is located between the receiving position 311 and the discharging position 312 and penetrates the screening assembly 30 in a third direction. The screening groove 32 has a preset length so that workpieces 200 with a length less than or equal to the preset length fall into the screening groove 32. For example, the drive unit 13 can be a rotary cylinder, a motor, etc.
[0027] When the screening device 100 described above is in use, firstly, the feeding component 11 provides a plurality of stacked workpieces 200, and the rotating component 12 receives the bottom workpiece 200 among the plurality of workpieces 200 through the receiving groove 121; then, the driving component 13 drives the rotating component 12 to rotate, so as to move the bottom workpiece 200 located in the receiving groove 121 to the guide groove 21, so that the workpiece 200 moves through the guide groove 21 to the receiving position 311 of the inclined surface 31, while the abutting arc surface 122 of the rotating component 12 abuts against the workpiece 200 adjacent to the bottom workpiece 200, so as to prevent other workpieces 200 from moving into the guide groove 21, and ensure that the rotating component 12 transfers a single workpiece 200 out of the receiving groove 111; finally, the inclined surface 31 guides the workpiece 200 to move from the receiving position 311 toward the discharge position 312, so that workpieces 200 less than or equal to a preset length move into the screening groove 32, and workpieces 200 greater than the preset length move to the discharge position 312. In this way, the screening device 100 continuously supplies workpieces 200 to the inclined surface 31 through the feeding component 10 and the guiding component 20, and the inclined surface 31 and the screening groove 32 cooperate to screen workpieces 200 that are longer than the preset length, thereby achieving fast and accurate completion of the screening operation of workpieces 200 and improving screening efficiency.
[0028] In addition, the feeding assembly 10 provides a single workpiece 200 to the inclined plane 31 at a time through the rotating component 12, avoiding the collision and screening difficulties caused by multiple workpieces 200 being moved to the inclined plane 31 at once, thereby improving screening stability and screening accuracy.
[0029] It should be noted that if the length of workpiece 200 is greater than the preset length, workpiece 200 continues to move closer to the discharge position 312 after passing through the screening tank 32; if the length of workpiece 200 is less than or equal to the preset length, workpiece 200 falls directly into the screening tank 32. In the first direction, the end of inclined surface 31 adjacent to guide component 20 is higher than the end of inclined surface 31 away from guide component 20; in the second direction, the end of inclined surface 31 located at receiving position 311 is higher than the end of inclined surface 31 located at discharge position 312, thereby ensuring that inclined surface 31 guides workpiece 200 to slide from receiving position 311 toward discharge position 312.
[0030] Please see Figure 1 and Figure 4 In some embodiments, the screening assembly 30 includes a screening element 33 and a stop element 34. The screening element 33 is connected to the guide assembly 20 and has an inclined surface 31 and a screening groove 32. The stop element 34 is located at the end of the inclined surface 31 away from the receiving position 311 and is connected to the screening element 33. The stop element 34 is configured to abut against and stop the screened workpiece 200 from reaching the discharge position 312.
[0031] Thus, through the above-mentioned arrangement, the stop member 34 can abut against the screened workpiece 200 to stop the screened workpiece 200 from reaching the discharge position 312, so as to facilitate centralized processing of the screened workpiece 200 and thereby improve the screening effect.
[0032] Please see Figure 1 In some embodiments, the screening component 30 further includes a limiting member 35, which is located at the end of the inclined surface 31 away from the guide component 20 and connected to the screening component 33. The limiting member 35 is used to abut against and limit the workpiece 200 to the inclined surface 31.
[0033] Thus, through the above-mentioned arrangement, the limiting member 35 can abut against the end of the workpiece 200 away from the guide component 20 on the inclined surface 31 to limit the workpiece 200 to the inclined surface 31, preventing the workpiece 200 from leaving the inclined surface 31 due to inertia when it moves from the guide groove 21 to the inclined surface 31. This is beneficial for the inclined surface 31 to guide the workpiece 200 to perform the screening operation, thereby improving the screening stability.
[0034] Please see Figure 1 In some embodiments, the screening assembly 30 further includes a detection element 36, which is disposed near the screening slot 32 and connected to the screening element 33. The detection element 36 is electrically connected to the drive element 13 and is configured to detect the number of qualified screening workpieces 200. Exemplarily, the detection element 36 can be a proximity sensor or a position sensor.
[0035] Thus, through the above settings, after the qualified workpieces 200 are piled up to a preset number at the discharge position 312, the workpieces 200 closest to the receiving position 311 among the multiple qualified workpieces 200 are located at the slot opening of the adjacent screening tank 32. The detection component 36 can detect the workpieces 200 closest to the receiving position 311 among the multiple qualified workpieces 200, to determine that the number of qualified workpieces 200 has reached the preset number, and sends an electrical signal to the drive component 13, so that the drive component 13 stops driving the rotating component 12 to provide the workpieces 200 to be screened, thereby avoiding the accumulation of too many qualified workpieces 200 at the discharge position 312, which would cause the workpieces 200 to fall or fall from the inclined plane 31, thereby improving the screening stability.
[0036] Please see Figure 1 and Figure 4 In some embodiments, the screening component 30 further includes a holding member 37 disposed at the receiving position 311 and above the inclined surface 31. The holding member 37 is connected to the screening component 33 and is configured to hold the workpiece 200 moved to the receiving position 311 against the inclined surface 31.
[0037] Thus, through the above configuration, the holding member 37 can hold the workpiece 200 to the inclined surface 31 during the process of the workpiece 200 moving from the guide groove 21 to the receiving position 311, preventing the workpiece 200 from tilting or jumping during the process of sliding from the guide groove 21 to the inclined surface 31, ensuring that the workpiece 200 moves stably to the receiving position 311, thereby improving the guiding stability.
[0038] Please see Figure 1 In some embodiments, the screening component 30 further includes a receiving component 38, which is located below the screening groove 32 and is used to receive unqualified workpieces 200.
[0039] Thus, through the above configuration, the receiving component 38 can receive the unqualified workpieces 200, so as to facilitate centralized processing of the unqualified workpieces 200, thereby improving the screening quality.
[0040] Please see Figure 1 and Figure 2 In some embodiments, the guide groove 21 includes a guide groove 211 and a sliding groove 212. The guide groove 211 extends along a third direction and communicates with the receiving groove 111. The sliding groove 212 is inclined relative to the guide groove 211 and communicates with the guide groove 211. The sliding groove 212 is configured to guide the workpiece 200 to slide from the guide groove 211 to the inclined surface 31.
[0041] Thus, through the above configuration, the guide groove 21 can guide the bottommost workpiece 200 among multiple workpieces 200 to the sliding inclined groove 212, so that the sliding inclined groove 212 can use its inclined characteristics to guide the workpiece 200 to slide to the inclined surface 31, thereby realizing the function of the wire assembly guiding the workpiece 200.
[0042] Please see Figure 2 In some embodiments, the cross-section of the guide groove 211 in the second direction decreases along the direction from the feeder 11 toward the guide assembly 20.
[0043] Thus, through the above configuration, the guide groove 211 can be made to have a large upper opening and a small lower opening, so that the guide groove 211 can stably receive the workpiece 200 conveyed by the rotating component 12, so as to accurately guide the workpiece 200 to the sliding inclined groove 212, thereby improving the guiding accuracy of the guide assembly 20.
[0044] Please see Figure 1 In some embodiments, the feeder 11 includes a feed body 112 and a cover plate 113. The feed body 112 is located on one side of the guide assembly 20 and has a receiving groove 111. The feed body 112 is configured to receive the workpiece 200. The cover plate 113 covers the receiving groove 111 and is detachably connected to the feed body 112.
[0045] Thus, through the above configuration, the feeding body 112 and the cover plate 113 are detachably connected, so that the feeding component 11 forms a split structure, which facilitates the replenishment of the workpiece 200 to be screened to the receiving trough 111, thereby achieving continuous supply of workpiece 200 and improving screening efficiency.
[0046] Please see Figure 1 and Figure 2 In some embodiments, the feed body 112 is provided with a relief groove 114, which is located at one end of the feed body 112 adjacent to the guide component 20 and on the wall of the receiving groove 111. The relief groove 114 is used to avoid the rotating component 12.
[0047] Thus, through the above-mentioned arrangement, the avoidance groove 114 can avoid the rotating part 12 rotating in the receiving groove 111, preventing the rotating part 12 from colliding with the feeding body 112, thereby improving the feeding stability of the feeding part 11.
[0048] The working process of the screening device 100 described above is roughly as follows: First, the feeding component 11 provides a plurality of stacked workpieces 200, and the rotating component 12 receives the bottom workpiece 200 among the plurality of workpieces 200 through the receiving groove 121. Then, the driving member 13 drives the rotating member 12 to rotate, so as to move the workpiece 200 located at the bottom of the receiving groove 121 to the guide groove 21, so that the workpiece 200 moves to the receiving position 311 of the inclined surface 31 via the guide groove 21. At the same time, the abutting arc surface 122 of the rotating member 12 abuts against the workpiece 200 adjacent to the bottom workpiece 200, so as to prevent other workpieces 200 from moving into the guide groove 21, and ensure that the rotating member 12 transfers a single workpiece 200 out of the receiving groove 111. Finally, the inclined plane 31 guides the workpiece 200 from the receiving position 311 toward the discharging position 312, so that workpieces 200 longer than the preset length move into the screening tank 32 and workpieces 200 longer than the preset length move to the discharging position 312, thereby achieving a fast and accurate completion of the screening operation of workpieces 200 and improving screening efficiency.
[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
