Description

Technical Field

[0001] The invention relates to the field of textile machinery, in particular to a high-speed rapier loom. Background Art

[0002] like Figure 1 and 2 As shown, this is the technical solution previously applied for by the applicant (patent number: 201911098547.9), which discloses a braiding machine that can realize twist weaving, including two front and rear heald frames, an opening power group for driving the front heald frame to move left and right, and a heald lifting power group for driving the two heald frames to move up and down. The above scheme has the following defects: 1. The heald drawing power group includes a gear transmission and a speed change structure, which is used to change the power of the loom's main drive motor and transmit it to the swing mechanism in the heald drawing power group. The swing mechanism swings back and forth to drive the two heald drawing rods to make reciprocating rotation and swing within a certain range, and then drive the front and rear heald frames to achieve up and down movement through the adapter; but in the above scheme, the swing mechanism and the heald drawing rod are arranged in the same plane, so that the overall footprint of the heald drawing power group is large, which is not conducive to being integrated with the loom frame. At the same time, in the above scheme, the translational motion of the output rod in the swing mechanism is converted into the reciprocating rotation of the heald drawing rod, and then the rotation is converted into up and down motion through the adapter, resulting in the output of the driving force not being direct enough; 2. The power transmission structure of the loom's main drive motor and the opening power group and the heald drawing power group is relatively complicated, time-consuming to install, and the maintenance frequency is high and the cost is high.

[0003] To solve the above-mentioned defects, the applicant later proposed a new high-speed rapier loom, such as Figure 3 and Figure 4 As shown, see patent CN202311229695.6 for details. In this patent, a swing mechanism that swings up and down is adopted, and through an L-shaped connector, the power output from the swing mechanism can directly drive the heald frame to move up and down, reducing the loss of force in the conversion process and improving the transmission efficiency. At the same time, the power of the opening power group and the heald lifting power group is penetrated by the same two-way transmission shaft, eliminating the power transmission structure between the loom main drive and the opening power group, improving the integration of the opening power group and the heald lifting power group, and simplifying the power transmission structure between the loom main drive and the opening power group and the heald lifting power group.

[0004] However, in actual production, the applicant found the following defects:

[0005] 1. Because in the above scheme, the power group of the heald raising needs to be on both sides of a set of heald raising and weft sharing cam groups (such as Figure 4 The upper and lower sides or Figure 2 Both the front and rear sides of the rapier loom are provided with a heald swing arm, but the heald swing arm can only complete one back-and-forth swinging action after the cam rotates one circle, which makes it difficult to increase the speed of the rapier loom;

[0006] 2. In the above scheme, if Figure 3 As shown, the heald rod used to connect the heald frame is an integral square tube. If a fault occurs, the square tube needs to be removed as a whole. Since the square tube is very long and has many connection nodes, the overall removal solution requires a lot of manpower and is very inconvenient.

[0007] 3. In the currently used harness power group, the positions of the harness common weft cam group and the harness swing arm are fixed, and the gap cannot be easily adjusted. If the loom speed is to be adjusted, the cam can only be replaced. At the same time, since the gap cannot be easily adjusted, the removal of the cam is also troublesome.

[0054] The present invention is further described in detail below in conjunction with the embodiments. It should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like herein indicate directions or positional relationships based on the attached Figure 5 The orientation or positional relationship shown is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0055] This embodiment provides a high-speed rapier loom. Figure 5 and Figure 6 As shown, it includes a frame, a power box is arranged on the left side of the frame, and the power box is composed of an input gear set 5, an opening power set 3 and a heald lifting power set 4. The right side of the frame is provided with heald frames 1 and 2 arranged in a forward and backward direction and a T-shaped connector 9, an L-shaped connector 8 and a heald lifting arm 6 located below the heald frames. The input gear set 5 is used to provide power to the opening power set 3 and the heald lifting power set 4. The opening power set 3 is connected to the front heald frame 1 by a transmission mechanism as shown in FIG. Figure 1 The transition structure 10 shown in the figure is connected to realize the left and right movement of the front heald frame 1 (the transition structure 10 can realize the front heald frame 1 to move both up and down and left and right, which belongs to the existing structure). The heald drawing power group 4 is connected to the heald drawing rod 7, and the two heald drawing rods 7 extend to the bottom of the front heald frame 1 and the rear heald frame 2 respectively, and are used to drive the T-shaped connector 9 and the L-shaped connector 8 to rotate back and forth. The rotation of the T-shaped connector 9 and the L-shaped connector 8 drives the front heald frame 1 and the rear heald frame 2 to move up and down through the heald drawing arm 6.

[0056] like Figure 6 As shown, the input gear set 5, the opening power set 3 and the heald power set 4 are integrated in a housing. Figures 7 to 10 As shown, the heald power group 4 includes a heald input shaft 401 and a mounting shaft 402, the input gear group 5 outputs power to the heald input shaft 401, the two ends of the heald input shaft 401 are rotatably connected to the box body through bearings, and the two ends of the mounting shaft 402 are fixed to the box body, and two heald common weft cam groups 403 are fixed on the heald input shaft 401, and the heald common weft cam group 403 includes a cam 1 4031 and a cam 2 4032, and the mounting shaft 402 is connected to the heald common weft cam group 403 through bearings. The two heald lifting swing arms 405 correspond to each other. The heald lifting swing arms 405 are provided with a roller 1 406 matched with a cam 1 4031 and a roller 2 407 matched with a cam 2 4032. The cam 1 4031 pushes the roller 1 406 to make the heald lifting swing arm 405 swing to the left around the mounting shaft 402. The cam 2 4032 pushes the roller 2 407 to make the heald lifting swing arm 405 swing to the right around the mounting shaft 402. The upper end of the heald lifting swing arm 405 is rotatably connected to the heald lifting connecting rod 701.

[0057] By adopting the mode of cooperating the single-sided heddle-raising swing arm 405 with the heddle-raising common weft cam group 403 and designing the cam shape, the heddle-raising swing arm 405 can swing back and forth 3 times during one rotation. Compared with the existing rapier loom, the power can be increased by 3 times, which greatly improves the production efficiency.

[0058] The fixing structure between the two ends of the mounting shaft 402 and the box body is as follows Figure 7As shown, an outer convex shaft hole 408 is integrally formed at the connection between the box body and the installation shaft 402, and the side wall of the outer convex shaft hole 408 is provided with a screw hole and a tightening bolt 409 is threadedly connected. The end of the installation shaft 402 can just pass through the outer convex shaft hole 408, and the installation shaft 402 is fixed by tightening the tightening bolt 409.

[0059] To achieve the adjustable gap between the heald swing arm 405 and the heald weft co-weft cam group 403, as shown in FIG. Figures 8 to 10 As shown, the hoisting power group 4 includes a sleeve 410 and a hoop 411, and the sleeve 410 is sleeved on the installation shaft 402. The sleeve 410 includes an eccentric section 4101 and a locking section 4102. The locking section 4102 is divided into several pieces along the circumferential direction. The hoop 411 is arranged on the outer wall of the locking section 4102. The locking section 4102 is gathered by the hoop 411, so that the sleeve 410 is fixed to the installation shaft 402, and the hoisting swing arm 405 is installed on the outer wall of the eccentric section 4101 through a bearing. When adjusting the gap, loosen the tightening bolt 409 so that the installation shaft 402 can rotate relative to the box body. At this time, one hand holds the heald swing arm 405 tightly, and the other hand gives the installation shaft 402 a rotating force. The rotation of the installation shaft 402 drives the shaft sleeve 410 to rotate. Since the heald swing arm 405 and the shaft sleeve 410 are connected by a bearing, the rotation of the eccentric section 4101 of the shaft sleeve 410 changes the position of the heald swing arm 405, thereby changing the gap between the heald swing arm 405 and the heald common weft cam group 403. In this way, the swing speed of the heald swing arm 405 can be changed, and the switching of different fabric modes such as fork weaving, twist weaving, and flat weaving of the rapier loom can be realized without disassembling and replacing the cam. At the same time, since the gap between the heald swing arm 405 and the heald common weft cam is adjustable, when the gap is adjusted to the maximum, the heald common weft cam group 403 can be easily disassembled.

[0060] In order to facilitate the screwing of the mounting shaft 402, the present embodiment further provides a screwing structure 404 on the end surface of the mounting shaft 402 to facilitate the rotation of the shaft body, such as an inner hexagon, an outer hexagon, a slotted seam or a cross seam, etc. Fig. 9 As shown, this embodiment adopts an external hexagonal screwing structure 404.

The cam three 3051 pushes the roller three 306 to make the opening swing arm swing rightward around the opening swing arm shaft 302, and the cam four 3052 pushes the roller four 307 to make the opening swing arm swing leftward around the opening swing arm shaft 302. The two ends of the transmission rod 303 are respectively connected to the upper end of the opening swing arm and one end of the left-right moving rod 304, and the other end of the left-right moving rod 304 is connected to the upper end of the opening swing arm and the left-right moving rod 304.
