Description

Technical Field

[0001] The utility model relates to the technical field of jacquard machines, in particular to an intermediate driven jacquard machine connecting rod mechanism and a jacquard machine. Background Art

[0002] In the prior art, the knife-lifting power of the jacquard machine is generally set at one end of the frame. For example, Chinese utility model patent: 202321651972.8, an improved connecting rod mechanism for a jacquard machine; such as Chinese utility model patent: 202221577681.4, an eccentric wheel connecting rod mechanism of a jacquard machine. The technical solution is to set the power mechanism at the end of the frame and transmit the power to the swing shaft through the connecting rod. This form of operation will inevitably cause one of the connecting rods to be longer, and the connecting rod will vibrate during the power transmission process, causing the bearing to be easily damaged. In addition, the length of the frame will increase, the overall size of the jacquard machine will increase, and the amount of steel used and the overall cost will increase. Utility Model Content

[0005] The power mechanism is a direct drive motor, and the direct drive motor is directly connected to the power shaft.

[0006] The lengths of the first link and the second link are equal or close to each other.

[0007] A jacquard machine adopts the connecting rod mechanism of the above structure.

[0008] The utility model provides an intermediate driven jacquard machine connecting rod mechanism and a jacquard machine, in which a power shaft is arranged on a frame between two swing shafts, and an eccentric wheel and a connecting rod are used to transmit power to the swing shaft, which can effectively shorten the length of the connecting rod, make the power transmission more stable, and at the same time reduce the overall length of the jacquard machine to reduce the cost.

[0013] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0014] Embodiment 1:

[0015] like Figure 1 , Figure 2 , Figure 3 As shown, the utility model discloses an intermediate-driven jacquard machine connecting rod mechanism, comprising a frame 1 and a first swing shaft 2 and a second swing shaft 3 arranged at both ends of the frame 1, a power shaft 9 is arranged on the intermediate frame 1 at one end of the first swing shaft 2 and the second swing shaft 3, a first rocker arm 4 is arranged on the first swing shaft 2 at one end of the power shaft 9, a second rocker arm 5 is arranged on the second swing shaft 3 at one end of the power shaft 9, a first eccentric wheel 11 and a second eccentric wheel 10 are arranged on the power shaft 9, the installation angle difference between the first eccentric wheel 11 and the second eccentric wheel 10 on the power shaft 9 is 180°, a first wheel sleeve 12 is arranged on the first eccentric wheel 11, a second wheel sleeve 13 is arranged on the second eccentric wheel 10, a first connecting rod 6 is arranged between the first wheel sleeve 12 and the first rocker arm 4, a second connecting rod 7 is arranged between the second wheel sleeve 13 and the second rocker arm 5, a power mechanism is arranged on the frame 1, and the power mechanism is transmission-connected with the power shaft 9.

[0016] Among them, the frame 1 is the frame 1 of an existing jacquard machine, which generally includes two vertically arranged mounting plates. The first swing shaft 2 and the second swing shaft 3 are arranged between the two mounting plates. The first swing shaft 2 and the second swing shaft 3 are of the prior art, and swing arms are arranged thereon for driving the lifting of the lifting knife, and the specific structure will not be elaborated. The first wheel sleeve 12 is sleeved on the first eccentric wheel 11, and the two can rotate relative to each other; the second wheel sleeve 13 is sleeved on the second eccentric wheel 10, and the two can rotate relative to each other.

[0017] The power shaft 9 is arranged on the frame 1 between the first swing shaft 2 and the second swing shaft 3, and the power shaft 9 is located on one side of the frame 1 and has a short length. The power shaft 9 is parallel to the first swing shaft 2 and the second swing shaft 3. A first rocker arm 4 is arranged at the end of the first swing shaft 2, and a second rocker arm 5 is arranged at the end of the second swing shaft 3. Of course, the first rocker arm 4 and the second rocker arm 5 need to be at the same end, and the power shaft 9 is located between the two rocker arms. The first eccentric wheel 11 and the second eccentric wheel 10 are arranged on the power shaft 9. The first wheel sleeve 12 on the first eccentric wheel 11 is connected to the first swing arm through a first connecting rod 6, and the second wheel sleeve 13 on the second eccentric wheel 10 is connected to the second swing arm through a second connecting rod 7. When the power shaft 9 rotates, it drives the eccentric wheels to rotate. The first eccentric wheel 11 drives the first wheel sleeve 12 to perform a circular motion, and the second eccentric wheel 10 also drives the second wheel sleeve 13 to perform a circular motion. Finally, the first connecting rod 6 and the second connecting rod 7 reciprocate. At this time, the first rocker arm 4 drives the first swing shaft 2 to reciprocate, and the second rocker arm 5 drives the second swing shaft 3 to reciprocate, realizing the lifting and lowering of the jacquard machine.

[0018] The lengths of the first connecting rod 6 and the second connecting rod 7 are close. Specifically, it means that the power shaft 9 is arranged on the frame 1 at the middle part between the first swing shaft 2 and the second swing shaft 3 as much as possible. In this way, the distances from the power shaft 9 to the first swing shaft 2 and the second swing shaft 3 are basically the same, so the lengths of the first connecting rod 6 and the second connecting rod 7 are basically the same. In this form, both the first connecting rod 6 and the second connecting rod 7 can maintain a short length, so the power transmission of the power shaft 9 is relatively stable and the overall stability is high. If the power shaft 9 is arranged close to one side, the length of one of the connecting rods will increase, which will affect the stability of power transmission. Of course, when the power shaft 9 is arranged between the first swing shaft 2 and the second swing shaft 3, the length of the connecting rod will inevitably be shorter than that of the connecting rod in the prior art. Therefore, the stability of its power transmission will inevitably be better than that of the power transmission of the jacquard machine in the prior art. Therefore, arranging the power shaft 9 at the middle position between the first swing shaft 2 and the second swing shaft 3, and the lengths of the first connecting rod 6 and the second connecting rod 7 are the same or close is the optimal solution.

[0019] The power mechanism is a direct drive motor 8, and the direct drive motor 8 is directly connected to the power shaft 9. By using the direct drive motor 8 as the power mechanism, a speed reducer can be dispensed with, reducing the space occupied on the side of the frame 1. The direct connection between the direct drive motor 8 and the power shaft 9 means that the output shaft of the direct drive motor 8 can be directly used as the power shaft 9.
