Description
Technical Field
[0001] This utility model relates to the field of textile equipment technology, and in particular to a heddle lifting mechanism that facilitates the installation of a power source. Background Technology
[0002] The heald frame is an important component of a loom. It is a frame with heald rods and a drive mechanism, connected by upper and lower crossbeams and left and right side rails. After the healds are placed on the heald frame, the warp yarns that are threaded through the healds are gathered together. With the movement of the heald lifting mechanism of the loom, the heald frame moves up and down according to the program of the shedding device, which opens the warp yarns in layers, allowing the weft yarns to shuttle through the warp yarns and weave into fabrics with different patterns.
[0003] The heddle-lifting mechanism is one of the main components of weaving equipment. Weaving equipment has several heddle frames installed, with a small distance between adjacent frames. The traditional working principle of the heddle-lifting mechanism is as follows: each heddle frame is driven by an independent heddle-lifting mechanism, which includes a power source and a rocker arm mechanism to drive each heddle frame in a reciprocating up-and-down motion. The driving torque of the heddle-lifting mechanism is transmitted to the gear train through a coupling, causing an eccentric wheel fixed coaxially to rotate a full circle. The eccentric wheel, through an open connecting rod, causes a three-arm rocker arm to swing, and the three-arm rocker arm, through a heddle frame connecting rod, causes the heddle frames mounted on it to open up and down.
[0004] Since each heald frame is connected to a power source, and the power source itself has a certain volume, coupled with the small distance between two adjacent heald frames, it is difficult to install multiple power sources simultaneously on the weaving equipment. At the same time, since the heald frame moves up and down reciprocatingly, the swing direction of the rocker arm mechanism is constantly changing. Each time the rocker arm mechanism changes direction, it needs to overcome inertial force, which affects the stability of the rocker arm mechanism's movement. This not only increases the energy consumption of the power mechanism but also increases the wear rate of the rocker arm mechanism.
[0005] Therefore, how to ensure the stability of the swing arm mechanism while facilitating the installation of a power source on weaving equipment is an urgent problem to be solved. Utility Model Content
[0006] This utility model provides a lifting mechanism that facilitates the installation of a power source in order to solve the above-mentioned technical problems.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A heald frame lifting mechanism that facilitates the installation of a power source includes several heald frames mounted on a loom, each heald frame being drivenly connected to a heald frame lifting mechanism; each heald frame lifting mechanism includes a first main shaft and a second main shaft arranged parallel to each other on the loom, the first main shaft having a first linkage mechanism hinged to the heald frame, the second main shaft having a second linkage mechanism hinged to the heald frame, the second linkage mechanism being drivenly connected to the first linkage mechanism via an intermediate rod; the first linkage mechanism is also drivenly connected to a reciprocating drive mechanism, the reciprocating drive mechanism, the first linkage mechanism, the intermediate rod, and the second linkage mechanism working together to cause the heald frame to move up and down reciprocally; the second linkage mechanism is provided with an elastic tensioning member drivenly connected to itself.

Detailed Implementation
[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model. Example
[0016] like Figure 1 and Figure 2 The illustrated heddle-lifting mechanism, which facilitates the installation of a power source, includes several heddle frames 1 mounted on a loom. Each heddle frame 1 is driven and connected to a heddle-lifting mechanism. Each heddle-lifting mechanism includes a first main shaft 2 and a second main shaft 3 arranged parallel to each other on the loom. A first linkage mechanism 4, which is hinged to the heddle frame 1, is mounted on the first main shaft 2. A second linkage mechanism 5, which is hinged to the heddle frame 1, is mounted on the second main shaft 3. The second linkage mechanism 5 and the first linkage mechanism 4 are driven and connected via an intermediate rod 6. The first linkage mechanism 4 is also driven and connected to a reciprocating drive mechanism 7, which serves as the power source for the heddle-lifting mechanism. An elastic tensioning member 8 is provided at the second linkage mechanism 5 and is driven and connected to it. Meanwhile, the reciprocating drive mechanisms 7 driven and connected to the heddle frames 1 in odd-numbered positions and the reciprocating drive mechanisms 7 driven and connected to the heddle frames 1 in even-numbered positions are located on both sides of the first linkage 42.
[0017] In this embodiment, the reciprocating drive mechanism 7 uses a hydraulic rod to achieve reciprocating drive. During operation, the reciprocating drive mechanism 7, the first linkage mechanism 4, the intermediate rod 6, and the second linkage mechanism 5 work together to make the heald frame 1 move up and down reciprocally. In the vertical direction, when the heald frame moves to the highest or lowest point, it is at rest and begins to reverse direction. At this time, the reciprocating drive mechanism 7 and the two linkage mechanisms need to overcome inertial forces to move, which not only increases the energy consumption of the reciprocating drive mechanism 7 but also increases the wear rate. By setting an elastic tensioning element 8 at the second linkage mechanism 5, the elastic force can be released to provide power to the second linkage mechanism 5, thereby reducing the burden on the reciprocating drive mechanism 7, making the reciprocating drive mechanism 7 more stable in reversing direction, and improving its performance.
[0018] Preferably, in this embodiment, the first linkage mechanism 4 includes a first sleeve 41 rotatably mounted on the first main shaft 2. A first link 42, a second link 43, and a third link 44 are fixedly mounted on the first sleeve 41, forming a T-shaped structure. The free end of the first link 42 is hinged to the execution end of the reciprocating drive mechanism 7. The free end of the second link 43 is hinged to a fourth link 45, and the free end of the fourth link 45 is hinged to the heald frame 1. The free end of the third link 44 is hinged to one end of the intermediate rod 6.
[0019] Preferably, in this embodiment, the second linkage mechanism 5 includes a second sleeve 51 rotatably mounted on the second main shaft 3. A fifth link 52 and a sixth link 53 are fixedly mounted on the second sleeve 51, forming an L-shaped structure. The free end of the fifth link 52 is hinged to the end of the intermediate rod 6 away from the third link 44. The free end of the sixth link 53 is hinged to a seventh link 54, and the free end of the seventh link 54 is hinged to the heald frame 1. The elastic tensioning member 8 is connected to the sixth link 53 in a transmission manner.
[0020] Specifically, in this embodiment, the elastic tensioning member 8 includes a crossbeam 81 mounted on the loom, an adjusting screw 82 threadedly connected to the crossbeam 81, and a tension spring 83 with one end connected to the adjusting screw 82. The other end of the tension spring 83 is connected to the sixth link 53. The central axis of the adjusting screw 82 and the extension / retraction direction of the tension spring 83 are both parallel to the vertical direction. In the vertical direction, the tension spring 83 is located above the sixth link 53.
[0021] The length of the tension spring 83 can be adjusted by rotating the adjusting screw 82, thereby adjusting the tension of the tension spring 83. This ensures that the force generated by each tension spring 83 causes the position of each palm frame to change in a consistent manner, thus guaranteeing the movement accuracy of each palm frame and improving the weaving quality.
[0022] from Figure 1From the perspective of [the device], when the second link 43 rotates clockwise around the central axis of the first main shaft 2 (during which the heald frame 1 moves from top to bottom), the sixth link 53 rotates counterclockwise around the central axis of the second main shaft 3. The tension spring 83 is in a stretched state, and it can overcome the inertial force generated by the downward movement of the free end of the sixth link 53. When the sixth link 53 rotates clockwise around the central axis of the second main shaft 3, the overall length of the tension spring 83 becomes shorter, and its presence facilitates the clockwise rotation of the sixth link 53. Therefore, during the reciprocating movement of the heald frame 1, the tension spring 83 helps the reciprocating drive mechanism 7 control the movement of the first link mechanism 4 and the second link mechanism 5, thereby reducing the energy consumption of the reciprocating drive mechanism 7.
[0023] Working principle: from Figure 1 From the perspective of the device, when the heald frame 1 needs to be moved downward, the reciprocating drive mechanism 7 causes the first connecting rod 42 to rotate clockwise around the central axis of the first main shaft 2. During this process, the second connecting rod 43 and the third connecting rod 44 rotate clockwise around the central axis of the first main shaft 2 simultaneously. The fifth connecting rod 52 rotates counterclockwise around the central axis of the second main shaft 3 under the push of the intermediate rod 6, and the sixth connecting rod 53 also rotates counterclockwise around the central axis of the second main shaft 3 simultaneously. The fourth connecting rod 45 moves downward under the push of the second connecting rod 43, and the seventh connecting rod 54 also moves downward under the push of the sixth connecting rod 53, thereby moving the heald frame 1 downward.
[0024] When the heddle frame 1 needs to move upward from its lowest position, the reciprocating drive mechanism 7 can make the first connecting rod 42 rotate counterclockwise around the central axis of the first main shaft 2.
[0025] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
