Description

Technical Field

[0001] This utility model relates to the technical field of jacquard machine equipment, and in particular to an anti-deviation transmission mechanism for the lifting knife of an electronic jacquard machine. Background Technology

[0002] Warp shedding refers to the process on a loom where a portion of the warp threads are divided into upper and lower layers, creating a gap to allow the weft threads to pass through. This mechanism has various designs, but its main function is to sequentially cross and layer a certain number of warp threads. Warp shedding is a crucial step in textile manufacturing. Shedding mechanisms typically employ complex combinations of levers, conjugate cams, and connecting rods to achieve the up-and-down movement of the inner and outer needle lifting arms. During this up-and-down movement, the lifting plate experiences a lateral pulling force due to the eccentric rotation of the cam, causing it to shift during the lifting process. Therefore, patent publication number CN219450030U proposes a "lifting plate anti-deviation transmission mechanism for an electronic jacquard machine," which places the frame plate above the main shaft and uses a guide shaft to ensure the frame plate always moves vertically up and down, preventing the lifting plate from shifting due to lateral deviation of the frame plate.

[0003] In this solution, the initial height of the lifting plate can be adjusted by rotating the threaded column. However, since this solution does not have a locking structure for the threaded column, frequent vibrations during equipment operation will cause the threaded column to rotate, resulting in height errors at both ends of the lifting plate, which in turn causes the lifting knife to deviate. In view of the above reasons, this application proposes an anti-deviation transmission mechanism for lifting knives in an electronic jacquard machine. Utility Model Content

[0038] Example 1

[0039] like Figure 1-3 As shown, the present invention proposes an anti-deviation transmission mechanism for the lifting blade of an electronic jacquard machine, comprising a top plate 1, a frame plate 2 movably disposed at the bottom of the top plate 1, a guide shaft fixedly disposed at the bottom of the top plate 1, the guide shaft and the frame plate 2 being movably connected, an internal threaded sleeve 4 fixedly disposed at the bottom of the frame plate 2, a pull rod 2 3 fixedly disposed at the top of the internal threaded sleeve 4, the pull rod 2 3 being hingedly connected to the frame plate 2, a threaded post 5 for adjustment movably disposed inside the internal threaded sleeve 4, a pull rod 6 for connection movably disposed at the bottom end of the threaded post 5, a lifting blade plate 9 hingedly connected at the bottom of the pull rod 6, a locking ring 7 welded on the threaded post 5, multiple slots provided on the outside of the locking ring 7, the slots being adapted to the locking plate 802, a locking structure 8 for locking the threaded post 5 fixedly disposed at the top of the pull rod 6, and limit wheels 10 and limit grooves 11 for cooperating with the limit wheels 10 fixedly disposed on both sides of the lifting blade plate 9;

[0040] The locking structure 8 includes two vertical plates 801 and a locking plate 802 slidably connected thereto. The front and back of the locking plate 802 are provided with sliding grooves 809. The two vertical plates 801 are welded to the side of their proximity, and the sliding grooves 809 are movably connected to the sliding grooves 809. Two extension plates 803 are fixedly provided on one side of the vertical plates 801. The inner sides of the two extension plates 803 and the two vertical plates 801 are provided with limiting grooves. A crossbar 804 is welded to one side of the locking plate 802. The front and back of the locking plate 802 are provided with storage grooves 805. The storage grooves 805 are provided with locking blocks 808. A spring 806 is fixedly provided in the storage grooves 805. A rectangular plate 807 is welded to the other end of the spring 806. The rectangular plate 807 and the storage grooves 805 are slidably connected. One end of the locking block 808 is fixedly connected to the rectangular plate 807.

[0041] In this embodiment, when the threaded column 5 needs to be rotated to adjust the original height of the lifting plate 9, the two locking blocks 808 are first pressed inward. When the locking block 808 is retracted into the storage groove 805 and the end away from the storage groove 805 is in contact with the inner wall of the limiting groove, the horizontal bar 804 is held and pulled outward. The horizontal bar 804 drives the locking plate 802 to disengage from the slot. Then the threaded column 5 can be rotated to adjust the initial height of the lifting plate 9. After the adjustment is completed, the horizontal bar 804 is pushed inward. The horizontal bar 804 drives the locking plate 802, and the locking plate 802 drives the locking block 808. When the locking plate 802 is inserted into the slot to achieve the positioning of the threaded column 5, the locking block 808 also moves to the positioning slot of the vertical plate 801. The spring 806 applies a pushing force to the rectangular plate 807, and the rectangular plate 807 then drives the locking block 808 to pop out from the positioning slot, thus achieving the positioning of the locking plate 802.

[0042] Example 2

[0043] like Figure 1-4 As shown, based on Embodiment 1, the inner wall of the limiting slide 11 is provided with a shock-absorbing structure 12. The shock-absorbing structure 12 includes a horizontal plate 121 for installation. A damper 122 is fixedly installed on the top of the horizontal plate 121. A lower support seat 123 is fixedly installed on the outside of the damper 122. An upper support seat 124 is fixedly installed at the output end of the damper 122. A second spring 125 is sleeved on the damper 122. The second spring 125 is located between the upper support seat 124 and the lower support seat 123. An installation strip 126 is welded to the top of the upper support seat 124. Two push rods 127 are welded to the top of the mounting strip 126. When the lifting plate 9 falls and is about to reach the limit position, the mounting cover outside the limit wheel 10 will first contact the two push rods 127. The two push rods 127 press the upper support seat 124 through the mounting strip 126. The upper support seat 124 presses the output end of the damper 122 and the second spring 125. The cooperation of the second spring 125 and the damper 122 can achieve the purpose of shock absorption and buffering, thereby reducing the amplitude and impact force generated when the lifting plate 9 falls, and extending the service life of the equipment.

[0044] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
