[0024] The utility model provides a waste discharge mechanism.

[0025] Reference Figure 1-2In one embodiment of the utility model, the waste discharge mechanism includes a rolling device 1, a negative pressure component (not shown in the drawings) and a positive pressure component (not shown in the drawings). The rolling device 1 can rotate along its own axis, and the rolling surface 11 on the rolling device 1 rotates through the first position 2 and the second position 3 in sequence; the negative pressure component is set at the first position 2, and the negative pressure component is used to adsorb the waste piece 5 on the rolling surface 11; the positive pressure component is set at the second position 3, and the positive pressure component is used to release the adsorption state between the waste piece 5 and the rolling surface 11; and the rolling surface 11 is connected to the negative pressure component and the positive pressure component. Specifically, when the waste material 4 to be discharged passes through the first position 2, the negative pressure component is connected to the rolling surface 11, so that the corresponding position of the rolling surface 11 has negative pressure, and the rolling device 1 adsorbs the waste piece 5 to the rolling surface 11 under the action of the negative pressure component; the rolling device 1 rotates to the second position 3 with the adsorbed waste piece 5; at the second position 3, the positive pressure component is connected to the rolling surface 11, so that the negative pressure at the corresponding position of the rolling surface 11 can be released, and the waste piece 5 is released from the adsorption state under the action of the positive pressure component and detached from the rolling surface 11, thereby completing the removal of the waste piece 5 on the waste material 4 to be discharged. The waste discharge mechanism has the beneficial effects of simple structure and easy use.

[0026] Specifically, the waste discharge mechanism further includes a negative pressure device 6, which is disposed at the first position 2, and is disposed opposite to the negative pressure device 6; a passage 61 is disposed between the negative pressure device 6 and the negative pressure device, and the passage 61 is used for the waste material 4 to be discharged to pass through; the negative pressure device 6 is used to adsorb the waste material 4 to be discharged. The negative pressure device 6 and the negative pressure assembly adsorb the opposite sides of the waste material 4 to be discharged, respectively. It can be understood that the provision of the negative pressure device 6 can expand the scope of application of the waste material 4 to be discharged, can reduce the influence of factors such as the weight and area of ​​the waste material 4 to be discharged on the adsorption effect of the negative pressure assembly, reduce the risk of the waste material 4 to be discharged and the waste piece 5 being adsorbed by the negative pressure assembly together, further improve the adsorption accuracy of the waste piece 5 by the negative pressure assembly, and improve the usability of the waste discharge mechanism.

[0027] Specifically, the waste discharge mechanism also includes a collecting device 7, which is located below the second position 3 and is used to collect the waste pieces 5 that fall from the second position 3. The setting of the collecting device 7 is conducive to collecting the waste pieces 5 and facilitating subsequent processing. The collecting device 7 includes a suction assembly 71 and a receiving tray 72, and the receiving tray 72 is located below the second position 3; the receiving tray 72 is used to carry the waste pieces 5 that fall from the second position 3, and the suction assembly 71 is used to absorb the waste pieces 5 located on the receiving tray 72. The receiving tray 72 with a carrying space is arranged below the second position 3, and can collect the waste that has separated from the rolling surface 11 as much as possible to prevent the waste from being scattered everywhere. The suction assembly 71 can transfer the waste on the receiving tray 72 to prevent the waste from accumulating on the receiving tray 72 and exceeding the carrying capacity of the receiving tray 72, thereby helping to achieve a continuous waste removal process.

[0028] Specifically, the first position 2 is set at the bottom of the rolling device 1, and the range of the rotation angle of the rolling device 1 when the rolling device 1 rotates from the first position 2 to the second position 3 is 0° to 180°. It can be understood that, as a preferred solution, when the first position 2 is set at the bottom of the rolling device 1, a plurality of waste materials 4 to be discharged continuously pass through the bottom of the rolling device 1 through a feeding mechanism set in the horizontal direction, and combined with the rotation of the rolling device 1 along its own axial direction, the process of removing the waste pieces 5 can be continuously carried out, thereby achieving the removal of the waste pieces 5 and improving the work efficiency. The second position 3 is set at a rotation angle of 0° to 180 with the first position 2, which is conducive to the timely removal of the waste pieces 5 adsorbed on the rolling surface 11, shortening the distance of the waste pieces 5 being adsorbed.

[0029] Furthermore, the second position 3 further includes a scraper 8, which is arranged on the side of the positive pressure assembly away from the negative pressure assembly, and the scraping portion 81 of the scraper 8 abuts against the rolling surface 11. In order to prevent the waste pieces 5 adsorbed on the rolling surface 11 from being completely detached in the second position 3 and affecting the waste removal effect, the scraper 8 is arranged to abut against the rolling surface 11. When the waste pieces 5 that have not been detached pass through the scraper 8, they are scraped off the rolling surface 11 by the scraper 8.

[0030] Specifically, the rolling device 1 has a plurality of ventilation cavities 12 arranged around the rolling surface 11 at one end, and the other end of the ventilation cavity 12 is used for the gas of the negative pressure component or the positive pressure component to pass through. It can be understood that the rolling device 1 is an annular structure, the outer side of the annular shape of the rolling device 1 is the rolling surface 11, the negative pressure component and the positive pressure component are arranged on the inner side of the annular shape of the rolling device 1, the negative pressure component and the positive pressure component will not rotate with the rolling device 1, and the negative pressure component is located at the first position 2, and the positive pressure component is located at the second position 3. When the rolling device 1 rolls to the first position 2, the negative pressure component is connected to the ventilation cavity 12 rotated to the first position 2, and the negative pressure component sucks gas inwardly to form a negative pressure on the rolling surface 11 corresponding to the ventilation cavity 12 connected to the negative pressure component, thereby adsorbing the waste piece 5 to the rolling surface 11; the rolling surface 11 continues to roll forward with the waste piece 5 to the second position 3. At this time, the positive pressure component is connected to the ventilation cavity 12 rotated to the second position 3, and the positive pressure component discharges gas outwardly. The rolling surface 11 corresponding to the ventilation cavity 12 connected to the positive pressure component is released from the negative pressure state, and the waste piece 5 falls from the rolling surface 11.

[0031] Furthermore, the ventilation chambers 12 are arranged at intervals along the rotation direction of the rolling device 1, and the distance between two adjacent ventilation chambers 12 is the same as the distance between two adjacent waste materials 4 to be discharged. This arrangement can achieve the position of the rolling surface 11 corresponding to one ventilation chamber 12 to adsorb a waste piece 5 on the waste material 4 to be discharged, which is conducive to fully adsorbing the waste piece 5 on a single waste material 4 to be discharged, and is also conducive to improving the adsorption effectiveness of the rolling device 1.

[0032] Furthermore, the rotation speed of the rolling device 1 is the same as the passing speed of the waste material 4 to be discharged. That is, the time taken to pass through two adjacent ventilation cavities 12 along the rotation direction should be consistent with the time taken to pass through two adjacent waste materials 4 to be discharged along the passing direction. This setting enables the portion of the rolling surface 11 corresponding to each ventilation cavity 12 to be adsorbed to the waste material 5 during the rotation of the rolling device 1, further improving the adsorption effectiveness of the rolling device 1, and avoiding the situation where part of the rolling surface 11 fails to effectively adsorb the waste material when the speeds of the two are inconsistent.

[0033] The utility model also provides an RFID metal antenna manufacturing system, including a waste discharge mechanism of any of the above embodiments. The specific structure of the waste discharge mechanism is referred to the above embodiments. Since the RFID metal antenna manufacturing system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0034] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
