Description

Technical Field

[0001] This application relates to the technical field of automatic needle selection sheet arrangement equipment, and in particular to a needle selection sheet flipping mechanism for a needle sorting machine. Background Technology

[0002] In the textile manufacturing industry, knitting processes can create diverse fabric textures by arranging and combining different types of needle picks. As a core component of knitting machines, the arrangement of the needle picks directly determines the pattern, density, and structural characteristics of the fabric. With the increasing demand for personalized and complex textures in the textile industry, the flexibility and efficiency of needle pick arrangement have become important factors affecting production efficiency and product competitiveness.

[0003] In related technologies, needle sorting machines have multiple needle sorting strip holders, a needle sorting strip conveying mechanism, and a needle sorting strip support mechanism. The multiple needle sorting strip holders are used to place needle sorting strips of different models. The needle sorting strips are stacked horizontally in the holders. Individual needle sorting strips of each model are pushed sequentially from the holders to the conveying mechanism. The needle sorting strip groups arranged in sequence are then conveyed by the conveying mechanism to the support mechanism for tight arrangement.

[0004] Regarding the aforementioned technologies, the needle selection plates on the support mechanism need to be arranged closely in a vertical posture. Therefore, each needle selection plate needs to be flipped before entering the support mechanism so that it can smoothly enter the support mechanism and be arranged closely. Utility Model Content

[0005] In order to enable the needle selection plate group to be adjusted from a horizontal to a vertical position before entering the support mechanism, this application provides a needle selection plate flipping mechanism for a needle sorting machine.

[0006] The needle selection plate flipping mechanism of the needle sorting machine provided in this application adopts the following technical solution:

[0007] A needle selection plate flipping mechanism for a needle sorting machine includes a flipping wheel, a flipping spindle, and a flipping drive for driving the flipping spindle. The flipping spindle is vertically inserted and fixedly connected to the central axis of the flipping wheel, and the flipping drive is connected to one end of the flipping spindle.

[0008] By adopting the above technical solution, before the needle selection plates enter the support mechanism, a flipping drive is used to drive the flipping spindle, which in turn drives the flipping wheel to rotate. The flipping mechanism mainly consists of the flipping wheel, the flipping spindle, and the flipping drive. The flipping spindle is vertically inserted and fixedly connected to the central axis of the flipping wheel, ensuring the stability and reliability of the flipping wheel's rotation. The flipping wheel can act on the horizontally positioned needle selection plates, smoothly adjusting them from a horizontal to a vertical position, meeting the requirement that the needle selection plates on the support mechanism need to be arranged closely in a vertical position, ensuring that the needle selection plates can smoothly enter the support mechanism and be arranged closely.

[0009] Furthermore, the rotating wheel is provided with ratchet teeth in the circumferential direction for driving the selection needle plate.

[0010] By adopting the above technical solution, the ratchet enables the flipping wheel to form a more reliable engagement with the needle selector. The needle selector is embedded in the edge of the ratchet, preventing the needle selector from slipping during the flipping process. This ensures that the needle selector can accurately adjust its posture as the flipping wheel rotates, thereby improving the stability and accuracy of the flipping action.

[0011] Furthermore, there are multiple rotating wheels, and each rotating wheel is arranged in parallel with the others. A rotating guide plate is provided between two adjacent rotating wheels for abutting against the needle selection plate.

[0012] By adopting the above technical solution, multiple parallel rotating wheels act simultaneously on the needle selection plate, providing support and driving force at different positions on the needle selection plate. This results in a more uniform force on the needle selection plate during rotation, enhancing its stability compared to a single rotating wheel and preventing wobbling, deviation, or incomplete rotation. The rotating guide plate between adjacent rotating wheels abuts against the needle selection plate, providing auxiliary support and guidance during rotation. It provides additional support on the sides of the needle selection plate, further limiting its range of motion and keeping it within a predetermined plane during rotation, ensuring accurate adjustment from a horizontal to a vertical position.

[0013] Furthermore, it also includes a flipping guide for connecting with the needle selection plate support mechanism. The flipping guide has a limiting part on both sides of the flipping wheel and an extension part for connecting with the conveying mechanism. The table of the needle sorting machine is provided with a guide auxiliary support for fixing the extension part.

[0014] By adopting the above technical solution, the extension of the flipping guide bar is interconnected with the conveying mechanism, allowing the needle selector to smoothly transition from the conveying mechanism to the flipping wheel. The extension provides a continuous channel for the needle selector, preventing it from falling, misaligning, or jamming during the transition. The limiting part restricts the movement range of the needle selector, ensuring that after flipping, it enters the supporting mechanism along a predetermined path and position, achieving seamless connection between flipping and supporting, and guaranteeing the continuity and stability of the needle selector conveying.

[0015] Furthermore, a flipping side guide plate is provided between the limiting part and the flipping wheel.

[0016] By adopting the above technical solution, the flipping side guide plate can work together with the limiting part and the flipping wheel to more accurately position the needle selector. During the flipping process of the needle selector being driven by the ratchet, the flipping side guide plate restricts the position of the needle selector from the side, so that it can be kept in a proper position in both the horizontal and vertical directions. This provides a more accurate reference for the posture adjustment of the needle selector, ensuring that the needle selector completes the flipping at the correct angle and position and enters the supporting mechanism.

[0017] Furthermore, a cover for covering the needle selection plate conveying mechanism is installed on the table of the needle sorting machine. The edge of the cover is located adjacent to the flipping wheel. The cover is provided with an auxiliary pushing component on the upper side for pushing the accumulated needle selection plates into the needle selection plate supporting mechanism.

[0018] By adopting the above technical solution, the cover encloses the needle selection conveyor mechanism, preventing external dust and debris from entering the conveyor mechanism and avoiding needle jamming, damage, or misalignment. The edge of the cover is located adjacent to the flipping wheel, providing an installation platform for the auxiliary pushing component. The auxiliary pushing component can effectively push the accumulated needle selection pieces into the needle selection support mechanism, making the transition of the needle selection pieces from the conveyor mechanism to the flipping wheel more compact and smooth.

[0019] Furthermore, the auxiliary pushing component includes a pusher plate and a pusher cylinder for driving the pusher plate. The pusher cylinder is fixedly connected to the cover, and the pusher plate is located on one side of the needle selection plate support mechanism and installed at the piston rod end of the pusher cylinder.

[0020] By adopting the above technical solution, the pusher cylinder can provide a stable and controllable driving force to the pusher plate, ensuring that when the selector plates are stacked, the pusher plate has sufficient force to smoothly push the selector plates into the selector plate support mechanism. By controlling the extension and retraction of the piston rod of the pusher cylinder, the moving distance and position of the pusher plate can be precisely controlled, and the pusher plate can accurately push the stacked selector plates to the designated position of the selector plate support mechanism.

[0021] Furthermore, the flipping mechanism housing has a push-guiding inclined surface on its top side for cooperating with the auxiliary push component.

[0022] By adopting the above technical solution, when the pusher plate of the auxiliary push component pushes the needle selector, the inclined surface can optimize the push path of the auxiliary push component, making it easier for the needle selector to slide towards the support mechanism. Under inclined force, the needle selector can move more smoothly, reducing jamming and resistance during the push process and improving push efficiency.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Through the cooperation of the flipping drive, flipping spindle, and flipping wheels, the needle selector is accurately adjusted from a horizontal to a vertical position, meeting the requirements of the support mechanism for the vertical and tight arrangement of the needle selector, and ensuring that the needle selector smoothly enters the support mechanism. The circumferential ratchet of the flipping wheels prevents the needle selector from slipping during flipping. Multiple parallel flipping wheels, as well as components such as the flipping center guide plate and flipping side guide plate, enhance the stability and positioning accuracy of the needle selector during flipping, enabling the needle selector to complete the flipping at the correct angle and position and enter the support mechanism, ensuring the accuracy and consistency of the needle selector arrangement, and thus ensuring the accuracy of the fabric texture.

[0025] 2. The extension of the flipping guide bar connects with the conveying mechanism, and the limiting part cooperates with the supporting mechanism to achieve a smooth transition of the needle selector strip from the conveying mechanism to the flipping wheel and then to the supporting mechanism. This prevents the needle selector strip from falling, misaligning, or jamming during the transition, ensuring the continuity and stability of the conveying process. The cover encloses the needle selector strip conveying mechanism, blocking external debris from entering and preventing the needle selector strip from jamming, being damaged, or being misaligned. The auxiliary pushing component, in conjunction with the pushing guide inclined surface, can promptly handle accumulated needle selector strips, reducing pushing resistance and jamming, improving pushing efficiency, and ensuring smooth conveying and arrangement of the needle selector strips.

[0026] 3. The flipping mechanism consists of flipping wheels, flipping spindles, and flipping drive components. All components are securely connected. For example, the flipping spindle is vertically fixed to the central axis of the flipping wheels, ensuring the stability and reliability of the flipping wheels' rotation. This prevents components from becoming loose or damaged, thus reducing equipment maintenance costs. Attached Figure Description

[0034] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figure 1-6 The present application will be further described in detail with reference to the embodiments.

[0035] This application discloses a needle selection plate flipping mechanism for a needle sorting machine. (Refer to...) Figure 1 and Figure 2 The needle selection plate flipping mechanism of the needle header machine includes a flipping wheel 1, a flipping spindle 2, a flipping drive 3, a flipping center guide plate 4, a flipping side guide plate 5, and a flipping guide bar 6. The flipping spindle 2 is vertically inserted and fixedly connected to the central axis of the flipping wheel 1. The flipping drive 3 is mounted on the table of the needle header machine and connected to one end of the flipping spindle 2, thereby enabling it to drive the flipping spindle 2 to rotate axially. In this embodiment, the flipping drive 3 is preferably a servo motor.

[0036] Reference Figure 3 and Figure 4 The rotating wheel 1 is provided with ratchet 11 around its circumference for driving the needle selector. The ratchet 11 enables the rotating wheel 1 to form a more reliable engagement with the needle selector. The needle selector is embedded in the edge of the ratchet 11, preventing the needle selector from slipping during the rotation process. This ensures that the needle selector can accurately adjust its posture as the rotating wheel 1 rotates, thereby improving the stability and accuracy of the rotation action.

[0037] Reference Figure 4 In this embodiment, the number of flipping wheels 1 is preferably two, and the two flipping wheels 1 are arranged parallel to each other. The parallel flipping wheels 1 act on the needle selection plate simultaneously, providing support and driving force at different positions of the needle selection plate, so that the needle selection plate is subjected to a more uniform force during the flipping process. Compared with a single flipping wheel 1, the stability of the needle selection plate flipping is enhanced, and the needle selection plate is prevented from shaking, shifting, or failing to flip properly during the flipping process.

[0038] A central guide plate 4 is located between two rotating wheels 1, and two rotating side guide plates 5 are respectively provided on both sides away from the central guide plate 4. Both the central guide plate 4 and the rotating side guide plates 5 can be used to abut against the needle selector plate, playing a role in auxiliary support and guidance when the needle selector plate is rotated. They provide additional support on the side of the needle selector plate, further limiting the range of movement of the needle selector plate, keeping the needle selector plate within a predetermined plane during the rotation process, and ensuring that it can be accurately adjusted from a horizontal posture to a vertical posture.

[0039] Reference Figure 4 and Figure 5 The flipping guide 6 is located adjacent to the flipping side guide plate 5 and away from the flipping drive member 3. The flipping guide 6 has limiting portions 61 on both sides of the flipping wheel 1 and extension portions 62 for interconnection with the conveying mechanism. The table of the needle sorting machine is provided with a guide auxiliary support member 7 for fixing the extension portions 62. The extension portions 62 of the flipping guide 6 interconnect with the conveying mechanism, allowing the needle selector to smoothly transition from the conveying mechanism to the flipping wheel 1. The extension portions 62 provide a continuous channel for the needle selector, preventing it from falling, misaligning, or jamming during the transition. The limiting portions 61 restrict the movement range of the needle selector, ensuring that after flipping, the needle selector can enter the supporting mechanism along a predetermined path and position, achieving seamless connection between flipping and supporting, and ensuring the continuity and stability of the needle selector conveying.

[0040] Reference Figure 6 The table of the needle sorting machine is equipped with a cover 8 for covering the needle sorting plate conveying mechanism. The edge of the cover 8 is located adjacent to the flipping wheel 1. The cover 8 is provided with an auxiliary pushing component 9 on its upper side for pushing the stacked needle sorting plates into the needle sorting plate support mechanism.

[0041] The auxiliary pushing component 9 includes a needle pusher plate 91 and a needle pusher cylinder 92 for driving the needle pusher plate 91. The needle pusher cylinder 92 is fixedly connected to the cover 8. The needle pusher plate 91 is located on one side of the needle selection plate support mechanism and is installed at the end of the piston rod of the needle pusher cylinder 92. The flipping mechanism cover 8 has a pushing guide inclined surface 81 on its top side for cooperating with the auxiliary pushing component 9.

[0042] The pusher cylinder 92 provides a stable and controllable driving force to the pusher plate 91, ensuring that when the selector pieces are stacked, the pusher plate 91 has sufficient force to smoothly push the selector pieces into the selector piece support mechanism. By controlling the extension and retraction of the piston rod of the pusher cylinder 92, the moving distance and position of the pusher plate 91 can be precisely controlled, allowing the pusher plate 91 to accurately push the stacked selector pieces to the designated position in the selector piece support mechanism. When the pusher plate 91 of the auxiliary pusher assembly 9 pushes the selector pieces, the inclined surface can optimize the pushing path of the auxiliary pusher assembly 9, making it easier for the selector pieces to slide towards the support mechanism.

[0043] The implementation principle of the needle selection plate flipping mechanism of a needle sorting machine according to an embodiment of this application is as follows: The flipping drive 3 is installed on the needle sorting machine table, driving the flipping spindle 2 to rotate axially, thereby driving the flipping wheel 1, which is vertically inserted and fixedly connected to its axis, to rotate. The ratchet 11 on the circumferential direction of the flipping wheel 1 engages with the edge of the needle selection plate, reliably driving the needle selection plate, preventing slippage, and enabling the needle selection plate to accurately adjust its posture with the flipping wheel 1, changing from a horizontal posture to a vertical posture. Two parallel flipping wheels 1 act on the needle selection plate simultaneously, providing support and driving force at different positions, making the needle selection plate evenly stressed, enhancing the flipping stability, and avoiding shaking, deviation, or incomplete flipping.

[0044] The central guide plate 4 is located between the two rotating wheels 1, and the side guide plates 5 are located on both sides of the rotating wheels 1 away from the central guide plate 4. Each guide plate abuts against the needle selector. When the needle selector flips, the guide plates provide auxiliary support and guidance, applying additional support force from the side to limit the range of movement of the needle selector, keeping it within a predetermined plane and ensuring accurate adjustment from horizontal to vertical. The extension 62 of the rotating guide bar 6 connects with the conveying mechanism, providing a continuous channel for the needle selector, allowing it to smoothly transition from the conveying mechanism to the rotating wheels 1 and preventing it from falling.

[0045] When the selected needle pieces are stacked, the auxiliary pushing component 9 on the housing 8 accurately pushes the stacked selected needle pieces to the designated position of the selected needle piece support mechanism. The push guide inclined surface 81 on the top side of the housing 8 works in conjunction with the auxiliary pushing component 9 to optimize the push path, making it easier for the selected needle pieces to slide towards the support mechanism under the push of the push plate 91, reducing jamming and resistance, and improving push efficiency.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
