BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0014] Combine the following Figure 1 The technical solution of the utility model is further illustrated by specific embodiments.

[0015] like Figure 1 The high-efficiency transmission device of the jacquard machine shown includes: a workbench 1, a bracket 2, a first jacquard plate 11 and a second jacquard plate 12. The bracket 2 is arranged on the workbench 1. In this embodiment, the number of the brackets 2 is 2, and they are arranged on the workbench 1 with a front and rear interval, and cooperate to provide transmission support for the first jacquard plate 11 and the second jacquard plate 12.

[0016] The first jacquard plate 11 and the second jacquard plate 12 are arranged in the bracket 2 with an interval up and down. In this embodiment, the bracket 2 is vertically provided with slide rails 13 located on both sides of the first jacquard plate 11 and the second jacquard plate 12. Both sides of the first jacquard plate 11 and the second jacquard plate 12 are respectively provided with sliders 10 located on the corresponding slide rails 13. Through the cooperation of the slide rails 13 and the sliders 10, the first jacquard plate 11 and the second jacquard plate 12 are guided to be lifted and lowered, thereby improving stability.

[0017] A first rack 15 extending downward is provided at the end of the first jacquard plate 11, and a second rack 14 extending downward is provided at the end of the second jacquard plate 12. A transmission shaft 8 extending between the first rack 15 and the second rack 14 is provided in the bracket 2. A gear 7 is provided on the transmission shaft 8. The gear 7 is respectively engaged with the first rack 15 and the second rack 14 on both sides. The gear 7 is used to realize the linkage of reverse lifting and lowering of the first rack 15 and the second rack 14. The structure is simple, the reliability is improved, and no chain and multiple cams are required.

[0018] In this embodiment, the bracket 2 is provided with a plurality of guide wheels 9 located outside the first rack 15 and the second rack 14 to guide the lifting of the first rack 15 and the second rack 14, thereby avoiding the problem of force deflection.

[0019] The workbench 1 is provided with a lifting drive mechanism for driving the first rack 15 or the second rack 14 to reciprocate up and down, thereby performing reverse lifting and lowering drive of the first jacquard plate 11 and the second jacquard plate 12. The front and rear two brackets 2 can share a transmission shaft 8, which reduces maintenance costs.

[0020] like Figure 1 As shown, the lifting drive mechanism includes a motor 3, a turntable 4 and a connecting rod 6. The turntable 4 is vertically arranged on the rotating shaft of the motor 3. A first pin 5 is eccentrically arranged on the turntable 4, and the eccentric rotation of the first pin 5 is driven by the motor 3.

[0021] The connecting rod 6 is arranged between the first pin 5 and the first rack 15 or the second rack 14 , and a second pin 16 is arranged on the first rack 15 or the second rack 14 connected to the connecting rod 6 , which is beneficial to the angle change of the connecting rod 6 .

[0022] like Figure 1 As shown, in this embodiment, the motor 3 is located below the gear 7, and the connecting rod 6 is arranged between the first pin shaft 5 and the second pin shaft 16 on the second rack 14. The first pin shaft 5 is adjusted in height as the turntable 4 rotates, and the connecting rod 6 rises and falls and changes its angle as the first pin shaft 5 rises and falls, driving the reciprocating rise and fall of the second rack 14, and the gear 7 is used to realize the reverse rise and fall of the first rack 15, thereby realizing the linkage of the reverse rise and fall of the first jacquard plate 11 and the second jacquard plate 12.
