Description

Technical Field

[0001] This invention relates to the field of textile machinery and equipment manufacturing technology, and in particular to a weft-laying trolley device with a yarn pressing function. Background Technology

[0002] In recent years, with the rapid development of high-end intelligent warp knitting machine equipment manufacturing at home and abroad, there is a growing need for warp knitting machines that can achieve high output, intelligence, and stability in order to weave quickly and maximize production capacity. This has played a rapid role in promoting the intelligent manufacturing and innovation of the entire textile equipment industry.

[0003] In the entire warp knitting machine equipment field, the products produced by this warp knitting machine are widely used in construction, agriculture, and industrial fields. With the continuous expansion of the market, the demand for this product has risen sharply, which has driven the rapid iteration and upgrading of the warp knitting machine. The pressing action is an essential knitting action in this type of warp knitting machine. Generally, the weft yarn is pressed by the weft warp carriage and then enters the knitting area to knit the finished product. In this process, the fast and stable pressing and laying of the weft yarn is particularly critical, which directly depends on the overall knitting speed and stability of the equipment. In the past, the traditional tension spring type was used, which determined the pressing action by tension. This action is a continuous cycle action. After long-term operation, the tension spring will fatigue and break. At the same time, there are also disadvantages such as insufficient stability and high noise, which ultimately affect the high-speed knitting of the warp knitting machine.

[0004] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a weft-laying carriage device with a yarn-pressing function to solve the problem that the tension spring will fatigue and break after long-term operation.

[0006] To achieve the above objectives, the present invention provides a weft-laying trolley device with a yarn-pressing function, comprising a frame and a weft-laying trolley mounted on the frame, and further comprising: a reciprocating motion mechanism mounted on the frame for driving the weft-laying trolley to reciprocate horizontally; a yarn-pressing execution mechanism mounted on the weft-laying trolley for performing yarn-pressing and avoidance actions; and a trajectory guiding mechanism mounted at both ends of the frame. When the weft-laying trolley drives the yarn-pressing execution mechanism to move synchronously to both ends of the frame, the trajectory guiding mechanism drives the yarn-pressing execution mechanism to switch from the avoidance action to the yarn-pressing action, thereby realizing the yarn-pressing action.

[0007] Optionally, the yarn pressing actuator includes a connecting shaft rotatably mounted on the weft laying trolley, a locking frame fixedly connected to the connecting shaft, two yarn pressing rods fixedly connected below the locking frame, and an abutment unit adapted to the machine frame installed on the connecting shaft.

[0008] Optionally, the abutment unit includes a rotating seat fixedly installed at the end of the connecting shaft away from the locking frame, a guide bar fixedly connected to the frame, and two rollers adapted to the guide bar rotatably connected to the rotating seat.

[0009] Optionally, the trajectory guiding mechanism includes trajectory blocks respectively disposed at both ends of the frame, the trajectory blocks are equipped with connecting parts adapted to the guide strip, and the trajectory blocks are provided with arc-shaped grooves adapted to the rollers.

[0010] Optionally, the connector includes a connecting plate fixedly installed on the track block. The bottom horizontal position of the connecting plate is consistent with the bottom horizontal position of the guide strip. The connecting plate has a plurality of first oblong holes, through which first bolts pass, and the connection between the first bolts and the guide strip is a threaded connection.

[0011] Optionally, a guide seat is fixedly connected to the track block, and the guide seat is slidably mounted on the frame.

[0012] Optionally, the reciprocating motion mechanism includes a first synchronous belt disposed on the frame, and the weft laying carriage and the first synchronous belt are fixedly connected. An anti-sway unit adapted to the weft laying carriage is installed on the frame, and a drive structure for driving the first synchronous belt to move is installed on the frame.

[0013] Optionally, the drive structure includes a first rotating shaft rotatably mounted at one end of the frame, a third rotating shaft rotatably connected to the other end of the frame, a first synchronous pulley fixedly sleeved on the outside of the first rotating shaft, a driven pulley fixedly sleeved on the outside of the third rotating shaft, and a first synchronous belt respectively sleeved on the outside of the first synchronous pulley and the driven pulley, a second synchronous pulley fixedly sleeved on the outside of the first rotating shaft, a servo motor mounted on the frame, a second rotating shaft fixedly connected to the output end of the servo motor, a driving pulley fixedly sleeved on the outside of the second rotating shaft, and the driving pulley and the second synchronous pulley connected by a second synchronous belt, and a translation component adapted to the servo motor mounted on the frame.

[0014] Optionally, the translation component includes several second bolts disposed on the frame, several second oblong holes are provided on the frame, the second bolts pass through the corresponding second oblong holes, and the connection between the second bolts and the servo motor is a threaded connection. A third oblong hole is provided on the frame, and the second rotating shaft passes through the third oblong hole.

[0015] Optionally, the anti-sway unit includes a slide rail fixedly installed on the frame, a plurality of threaded columns passing through the weft-laying trolley, an eccentric disc fixedly connected to the threaded column, a roller cooperating with the slide rail rotatably connected to the side of the eccentric disc away from the threaded column, a nut being fitted on the external thread of the threaded column, and the nut and the eccentric disc being located on opposite sides of the weft-laying trolley.

[0016] The beneficial effects of this invention are as follows: The reciprocating motion mechanism drives the weft-laying carriage to move back and forth horizontally relative to the frame, and the weft-laying carriage drives the yarn-pressing actuator to move synchronously. When the weft-laying carriage drives the yarn-pressing actuator to move to both ends of the frame, the trajectory guide mechanism drives the yarn-pressing actuator to switch from an avoidance action to a yarn-pressing action to achieve the yarn-pressing action. By driving the yarn-pressing actuator to perform the yarn-pressing action through the trajectory guide mechanism, the stability is improved, the risk of spring fatigue fracture is eliminated, the reliability of long-term operation is guaranteed, the noise is reduced, the mechanical forced drive avoids the impact noise of spring rebound, the working environment is improved, and the structure is simplified, eliminating the need for pneumatic components and control systems, significantly reducing manufacturing and maintenance costs.

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0021] Example 1, by Figure 1 , Figure 2 and Figure 5 The present invention includes a frame 1 and a weft-laying trolley 2 mounted on the frame 1. It further includes: a reciprocating motion mechanism mounted on the frame 1 for driving the weft-laying trolley 2 to reciprocate horizontally; a yarn-pressing actuator mounted on the weft-laying trolley 2 for performing yarn-pressing and avoidance actions; and a trajectory guiding mechanism located at both ends of the frame 1. When the weft-laying trolley 2 drives the yarn-pressing actuator to move synchronously to both ends of the frame 1, the trajectory guiding mechanism drives the yarn-pressing actuator to switch from avoidance to yarn-pressing action, thereby realizing the yarn-pressing action. The reciprocating motion mechanism drives the weft-laying trolley 2 to reciprocate horizontally relative to the frame 1. The weft-laying trolley 2 drives the yarn-pressing actuator to move synchronously. When the weft-laying trolley 2 drives the yarn-pressing actuator to move to both ends of the frame 1, the trajectory guide mechanism drives the yarn-pressing actuator to switch from the avoidance action to the yarn-pressing action to realize the yarn-pressing action. By driving the yarn-pressing actuator to perform the yarn-pressing action through the trajectory guide mechanism, the stability is improved, the risk of spring fatigue fracture is eliminated, the reliability of long-term operation is guaranteed, the noise is reduced, the mechanical forced drive avoids the impact noise of spring rebound, the working environment is improved, and the structure is simplified, eliminating the need for pneumatic components and control systems, which significantly reduces manufacturing and maintenance costs.

[0022] Example 2, based on Example 1, is... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7The yarn pressing actuator includes a connecting shaft 3 rotatably mounted on the weft laying carriage 2. A locking frame 4 is fixedly connected to the connecting shaft 3. Two yarn pressing rods 5 are fixedly connected below the locking frame 4. An abutment unit adapted to the frame 1 is mounted on the connecting shaft 3. The abutment unit includes a rotating seat 6 fixedly mounted at the end of the connecting shaft 3 away from the locking frame 4. A guide bar 8 is fixedly connected to the frame 1. Two rollers 7 adapted to the guide bar 8 are rotatably connected to the rotating seat 6. The trajectory guiding mechanism includes trajectory blocks 9 respectively disposed at both ends of the frame 1. The track block 9 is equipped with a connector that matches the guide bar 8. The track block 9 has an arc groove 10 that matches the roller 7. The connector includes a connecting plate 12 that is fixedly installed on the track block 9. The bottom horizontal position of the connecting plate 12 is the same as the bottom horizontal position of the guide bar 8. The connecting plate 12 has several first waist-shaped holes 13. A first bolt 14 passes through the first waist-shaped holes 13. The first bolt 14 and the guide bar 8 are connected by a threaded connection. A guide seat 11 is fixedly connected to the track block 9. The guide seat 11 is slidably installed on the frame 1. When the reciprocating motion mechanism drives the weft-laying carriage 2 and the yarn-pressing actuator to move, the weft-laying carriage 2 drives two rollers 7 to slide at the bottom of the guide bar 8. When the weft-laying carriage 2 moves to the end of the frame 1, the rollers 7 slide from the guide bar 8 into the arc-shaped groove 10. The arc-shaped groove 10 drives the rotating seat 6 and the connecting shaft 3 to rotate relative to the weft-laying carriage 2 through the rollers 7. The connecting shaft 3 drives the locking frame 4 and the yarn-pressing rod 5 to rotate, and the yarn-pressing rod 5 can then perform the yarn-pressing action. When the weft-laying carriage 2 moves in the opposite direction relative to the frame 1, the rollers 7 slide out of the arc-shaped groove 10, and the connecting shaft 3 and the yarn-pressing rod 5 rotate in the opposite direction. The yarn-pressing rod 5 can then switch from the yarn-pressing action to the avoidance action. Without pressing the yarn, the operator rotates the first bolt 14 to release the fixed relationship between the connecting plate 12 and the guide bar 8. The operator drives the track block 9 and the guide seat 11 to slide relative to the frame 1, and the connecting plate 12 moves relative to the guide bar 8, which changes the distance between the two track blocks 9. On this basis, the track block 9 can slide laterally, which can realize the adjustment according to the width of the equipment. Finally, the operator drives the first bolt 14 to rotate in the opposite direction, and the guide bar 8 and the connecting plate 12 are fixedly connected together by the first bolt 14. The design of the guide seat 11 increases the stability of the track block 9 when moving horizontally and reduces the possibility of the track block 9 tilting and shaking.

[0023] Example 3, based on Example 1, is... Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6The reciprocating motion mechanism includes a first synchronous belt 15 mounted on a frame 1, with the weft-laying carriage 2 fixedly connected to the first synchronous belt 15. An anti-sway unit adapted to the weft-laying carriage 2 is mounted on the frame 1. A drive structure for driving the first synchronous belt 15 is mounted on the frame 1. The drive structure includes a first rotating shaft 16 rotatably mounted at one end of the frame 1, and a third rotating shaft 27 rotatably connected to the other end of the frame 1. A first synchronous pulley 17 is fixedly sleeved on the outside of the first rotating shaft 16, and a driven pulley 28 is fixedly sleeved on the outside of the third rotating shaft 27. The first synchronous belt 15 is respectively sleeved on the outside of the first synchronous pulley 17 and the driven pulley 28. A second synchronous pulley 18 is fixedly sleeved on the outside of the first rotating shaft 16. A servo motor 19 is mounted on the frame 1, and a second rotating shaft 20 is fixedly connected to the output end of the servo motor 19. A driving pulley 22 is fixedly sleeved on the outside of the second rotating shaft 20. 22 and the second synchronous pulley 18 are connected by the second synchronous belt 23. The frame 1 is equipped with a translation component adapted to the servo motor 19. The translation component includes several second bolts 24 set on the frame 1. Several second oblong holes 25 are opened on the frame 1. The second bolts 24 pass through the corresponding second oblong holes 25. The connection between the second bolts 24 and the servo motor 19 is a threaded connection. The frame 1 is equipped with a third oblong hole 26. The second rotating shaft 20 passes through the third oblong hole 26. The anti-sway unit includes a slide rail 29 fixedly installed on the frame 1. Several threaded columns 30 pass through the weft laying carriage 2. An eccentric disk 31 is fixedly connected to the threaded column 30. A roller 32 that cooperates with the slide rail 29 is rotatably connected to the side of the eccentric disk 31 away from the threaded column 30. Nuts 21 are sleeved on the external threads of the threaded column 30. Nuts 21 and eccentric disk 31 are located on both sides of the weft laying carriage 2, respectively. The second rotating shaft 20 is driven to rotate by the servo motor 19. The second rotating shaft 20 drives the first rotating shaft 16 to rotate via the drive wheel 22, the second synchronous belt 23, and the second synchronous pulley 18. The first rotating shaft 16 then drives the first synchronous belt 15 to move via the first synchronous pulley 17. The first synchronous belt 15 drives the driven wheel 28 to move synchronously. The first synchronous belt 15 drives the weft-laying carriage 2 to slide relative to the frame 1. The weft-laying carriage 2 drives the roller 32 to slide on the slide rail 29. The design of the roller 32 and the slide rail 29 ensures that the weft-laying carriage 2 moves smoothly relative to the frame 1. The operator drives the second bolt 24 to rotate, releasing the fixed relationship between the servo motor 19 and the frame 1. The operator then drives the servo motor 19 to slide relative to the frame 1. The second rotating shaft 20 and the drive wheel 22 can be driven to move relative to the second synchronous wheel 18 so that the second synchronous belt 23 is in a taut state. Finally, the operator drives the second bolt 24 to rotate in the opposite direction, so that the servo motor 19 is fixed relative to the frame 1. The operator drives the nut 21 to rotate so that the nut 21 and the eccentric disk 31 no longer clamp the weft laying carriage 2. Then the operator drives the threaded column 30 and the eccentric disk 31 to rotate. The eccentric disk 31 and the roller 32 rotate around the threaded column 30 as the rotation center, changing the position of the roller 32 to ensure that the roller 32 is in close contact with the slide rail 29. Then the operator drives the nut 21 to rotate in the opposite direction so that the nut 21 and the eccentric disk 31 clamp the weft laying carriage 2, so that the threaded column 30 and the eccentric disk 31 are fixed relative to the weft laying carriage 2.
