[0030] The specific use mode and role of the embodiment are as follows:
[0031] In the utility model, Figure 1As shown, the conveyor track plate 9 is cut off at both ends, and when the equipment body 1 is in use, the conveyor support column 2 needs to be bolted to the conveyor chain so that the conveyor support column 2 can move from right to left. At this time, the needle cylinder and needle seat are assembled and glued and cured. The needle seat is on the frustum rod of the needle support rod 5. When the conveyor support column 2 continues to move from right to left, the contact roller 8 contacts the inclined surface of the triangular block of the conveyor track plate 9. The contact roller 8 and the conveyor track plate 9 are in rolling contact, which effectively prevents jamming. 2. Continue moving. The conveyor support column 2 drives the needle support rod 5 to continue moving, causing the needle support rod 5 to move along the inclined surface of the triangular block of the conveyor track plate 9 via the fixed support column 7. The contact roller 8 moves and descends along the inclined surface of the triangular block of the conveyor track plate 9, and the contact roller 8 drives the fixed support column 7 to move and descend synchronously. The fixed support column 7 drives the needle support rod 5 to move and descend synchronously, causing the needle support rod 5 to descend and compress the support rod spring 6. This causes the frustum rod of the needle support rod 5 to descend and disengage from the needle seat, as shown in the image. Figure 5 As shown, at this point, the needle holder loses its support and falls forward into the hopper under the protection of the needle guard plate 3, thus completing the needle removal operation. The needle guard plate 3 effectively prevents the needle from falling in other directions. The conveying support column 2 continues to move. When the contact roller 8 passes the lower corner of the triangular block of the conveying track plate 9, the support rod spring 6 releases its reaction force. Under the reaction force of the support rod spring 6, the needle support rod 5 rises. The needle support rod 5 drives the fixed support column 7 to rise synchronously. The fixed support column 7 then drives the contact roller 8 to move along the triangular block of the conveying track plate 9. The other inclined plane moves upward. When the contact roller 8 disengages from the triangular block on the other inclined plane of the conveyor track plate 9, the needle support rod 5 rises and resets completely. The conveyor support column 2 continues to move, and then the next round of needle assembly and use can be carried out. Note that when the contact roller 8 is between the upper and lower horizontal plates of the conveyor track plate 9, the needle support rod 5 will not move up and down. Therefore, when the needle seat is fitted on the frustum rod of the needle support rod 5, the needle support rod 5 will not descend. Moreover, before the contact roller 8 enters the through groove of the conveyor track plate 9, the needle cylinder and needle seat have been assembled and glued and cured.
[0032] Example 2:
[0033] The difference from Embodiment 1 is that the regular hexagonal groove of the limiting circular plate 4 can also be set as a regular heptagonal groove, so that the limiting circular plate 4 can only be rotated by a special tool that cooperates with the regular heptagonal groove, thus preventing non-workers from rotating and disassembling the limiting circular plate 4.
[0034] Example 3:
[0035] Different from the first embodiment, the regular hexagonal slot of the fixed bearing column 7 can also be set as a regular heptagonal slot, so that the fixed bearing column 7 needs to be rotated by a special tool matched with the regular heptagonal slot, preventing non-workers from rotating and disassembling the fixed bearing column 7.
