Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically a control mechanism for a multi-mode rising rake. Background Technology

[0002] In the textile production process, textile tensioning equipment, as a crucial component of textile machinery, plays a key role in generating tension and forming loops in the fabric. Currently, mainstream computerized flat knitting machines primarily use rollers, and the rakes are uniformly raised and lowered, preventing the selection of individual rakes for lifting. This results in a relatively simple operating mode, making it impossible to dynamically adjust the rake combination based on different yarn characteristics (such as thickness and elasticity) or textile processes. Alternatively, frequent machine stops for manual adjustments are necessary, reducing production efficiency. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, this utility model provides a control mechanism for a multi-mode rising rake, which can automatically select different combinations of rakes to rise, is easy to use, and has high production efficiency.

[0004] This utility model provides a control mechanism for a multi-mode rising rake, including a pushing mechanism. The pushing mechanism has a rotating shaft, and the rotating shaft has several pushing tooth groups. Each pushing tooth group includes multiple pushing teeth, with the pushing teeth of each group evenly arranged around the rotating shaft. At least one set of rotating teeth is provided on the rotating shaft. The pushing mechanism has a positioning component that cooperates with the rotating teeth. Multiple stops are fixedly arranged along the movement trajectory of the rotating teeth. Each stop has a rotation angle, and a return spring is provided at the rotational connection of the stop. When the rotating teeth move, they contact the stops, causing the rotating teeth to rotate around the rotating shaft by a certain angle. A chamber is arranged on one side of each pushing tooth group. Sliding grooves are provided on the outer side of each chamber, corresponding to the positions of the pushing tooth groups. The pushing teeth on the pushing tooth groups closest to the chambers extend into the chambers through the sliding grooves, and the pushing teeth extending into the chambers are slidably connected to the sliding grooves. The rake body is slidably disposed within the chambers.

[0005] In a preferred embodiment, the pushing mechanism includes a rotating shaft with positioning end plates at both ends. The rotating shaft is rotatably connected to the positioning end plates. Swing arms are fixedly mounted at both ends of the rotating shaft. The rotating shaft is rotatably mounted between the outer and inner sides of the swing arms. The rotating shaft is driven to revolve around the rotating shaft by the swing arms.

[0006] In a preferred embodiment, the stop block is mounted on the positioning end plate around the rotating shaft.

[0007] In a preferred embodiment, the chambers are evenly arranged between the positioning end plates.

[0008] In a preferred embodiment, the positioning element is a positioning plate, which is rotatably mounted on the swing arm.

[0009] In a preferred embodiment, the pushing tooth assembly is an integral structure and is star-shaped, with each star-shaped corner of the pushing tooth assembly serving as a pushing tooth.

[0010] In a preferred embodiment, the end of the chamber near the rotation axis is arc-shaped, the other end of the chamber is straight, and the slide groove is arc-shaped.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] This invention utilizes the cooperation of rotating teeth and stop blocks to control the combination of different arrangements of pushing teeth entering the chamber, achieving selective lifting of specific rake bodies to meet diverse operational needs. It is easy to use and highly efficient. A positioning component locks the position of the rotating teeth, preventing malfunctions and ensuring the pushing teeth remain fixed when reversing to push the rake. The side-by-side arrangement of multiple pushing tooth groups and rake bodies supports modular expansion, allowing for flexible adjustment of the number or layout of rakes as needed. Mode selection and action execution are completed simply by rotating the shaft in both directions, facilitating integration with automated control systems and reducing the need for manual intervention.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a control mechanism for a multi-mode rising rake includes a pushing mechanism, a rotating shaft 4 on the pushing mechanism, several pushing tooth groups 5 on the rotating shaft 4, each pushing tooth group 5 including multiple pushing teeth 501, the pushing teeth 501 of each pushing tooth group 5 being evenly arranged around the rotating shaft 4, at least one set of rotating teeth 6 being evenly arranged around the rotating shaft 4, a positioning member 9 on the pushing mechanism cooperating with the rotating teeth 6, and multiple stops 7 fixedly arranged on the movement trajectory of the rotating teeth 6. A return spring is provided at the rotating connection of the stop block 7, which has a rotation angle. When the rotating tooth 6 moves, it touches the stop block 7, causing it to rotate around the rotation axis 4 by a certain angle. A chamber 8 is arranged on one side of the push tooth assembly 5. Slide grooves 801 are provided on the outer side of the chamber 8 and at the positions corresponding to the push tooth assembly 5. The push teeth 501 on the push tooth assembly 5 that are close to the chamber 8 extend into the chamber 8 through the slide grooves 801. The push teeth 501 that extend into the chamber 8 are slidably connected to the slide grooves 801. The rake body 10 is slidably arranged inside the chamber 8. The end of the chamber 8 that is close to the rotation axis 4 is arc-shaped, and the other end is straight. The slide groove 801 is arc-shaped.

[0022] The driving mechanism includes a rotating shaft 1, with positioning end plates 2 at both ends of the rotating shaft 1. The rotating shaft 1 is rotatably connected to the positioning end plates 2. Swing arms 3 are fixedly mounted at both ends of the rotating shaft 1. A rotating shaft 4 is rotatably positioned between the outer and inner sides of the swing arms 3. The rotating shaft 1 drives the rotating shaft 4 to revolve around the rotating shaft 1 via the swing arms 3. Stop blocks 7 are arranged around the rotating shaft 1 on the positioning end plates 2. Chambers 8 are evenly arranged between the positioning end plates 2. Positioning elements 9 are positioning plates, rotatably mounted on the swing arms 3.

[0023] Example 2

[0024] like Figure 5 As shown, the push tooth assembly 5 is a one-piece structure in a star shape, with each star point of the push tooth assembly 5 serving as a push tooth 501. Other structures are consistent with Embodiment 1.

[0025] When selecting which rake bodies 10 arranged side-by-side need to rise, the rotating shaft 1 rotates (counterclockwise), thereby driving the swing arm 3 to rotate. This causes the rotating teeth 6 to rotate along with the swing arm 3. The rotating teeth 6 will touch the stop block 7 along its rotation path. At this time, the stop block 7 does not rotate. Each time the rotating teeth 6 encounters a stop block 7, the rotating teeth 6 will rotate around the rotating shaft 4 by a certain angle. Each time the rotating teeth 6 rotates around the rotating shaft 4 by a certain angle, the pushing tooth assembly 5 will also rotate around the rotating shaft 4. Furthermore, the pushing teeth 501 of the pushing tooth assembly 5 will have different arrangements, meaning that the pushing teeth 501 of different pushing tooth assemblies 5 will extend into the interior of the chamber 8. This allows for control of the rotation... The rotation angle of the rotating tooth 6 is used to control the different pushing teeth 501 of the pushing tooth group 5 to enter the interior of the chamber 8. After the selected pushing tooth 501 of the pushing tooth group 5 enters the chamber 8, the positioning member 9 rotates at a certain angle so that the positioning member 9 abuts against the rotating tooth 6 to prevent the rotating tooth 6 from moving again. Then the rotating shaft 1 starts to reverse (rotate clockwise). Since the stop block 7 has a rotation angle on the positioning end plate 2, when the fixed rotating tooth 6 touches the stop block 7 again on the return path, the stop block 7 will rotate at a certain angle. The fixed rotating tooth 6 will pass over the stop block 7 and the pushing teeth 501 that enter the interior of the chamber 8 will push the corresponding rake body 10 respectively, and the outer end of the rake body 10 will rise.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
