Description

Technical Field

[0001] This invention relates to the field of mechanical equipment technology, specifically to a linear gripping device and gripping method for vortex spinning. Background Technology

[0002] Vortex spinning, also known as air-jet vortex spinning, uses air vortices instead of traditional mechanical twisting. After drafting, the fiber bundles pass through a spiral channel to form a yarn core and wrapping structure, allowing direct yarn production from slivers. It is one of the free-end spinning methods. During vortex spinning, materials often need to be gripped and transferred. Current gripping mechanisms are quite complex, with many being hydraulically driven. While hydraulic systems offer high gripping force and are suitable for heavy loads, they are prone to leakage and contamination. Hydraulic gripping mechanisms are also inconvenient for gripping smaller materials, and their design is complex. Furthermore, existing spinning gripping equipment can only grip a fixed quantity, making it difficult to freely set the gripping amount as needed, and the clamping force is often insufficient, affecting the gripping effect.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses a spinning gripping mechanism [CN205114490U], which includes a base plate on which multiple gripping mechanisms are arranged. Each gripping mechanism is provided with a support base, which is composed of multiple support plates connected to each other. Multiple grippers are provided on the support base, and a connecting plate is provided at the tail of each gripper. A cylinder is provided at the rear end of the support base, and a cylinder shaft is provided on the cylinder. The cylinder shaft is connected to one end of the connecting plate. An upper connecting hole is provided at the tail of each gripper, and the support plates are located at the upper and lower ends of the grippers respectively.

[0004] The above solution has solved to some extent the problems of inconvenience and pollution caused by existing hydraulic yarn gripping equipment when gripping small materials. However, the solution still has many shortcomings, such as: it can only grip a fixed quantity, making it difficult to freely control the gripping amount as needed, and the gripping force is not good, affecting the gripping effect.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0039] like Figure 1-7 As shown, a linear gripping device for vortex spinning includes a mobile lifting box 1, a sliding assembly frame 2 on one side of the mobile lifting box 1, a position sensing component 3 between the sliding assembly frame 2 and the mobile lifting box 1, a plurality of clamping components 5 connected inside the sliding assembly frame 2 via a lifting mechanism 4, a push rod structure 6 at the upper end of the clamping component 5 that can drag the clamping component 5 up and down, and adjustable swing components 7 symmetrically arranged on both sides of the clamping component 5.

[0040] The lifting mechanism 4 includes a lifting groove 41 set in the inner wall of the sliding assembly frame 2. A lifting connecting rod 42 is slidably and vertically arranged in the lifting groove 41. A positioning crossbar 43 is arranged parallel to the upper end of the lifting connecting rod 42. A lifting drive cylinder 44 is arranged on the positioning crossbar 43. The output end of the lifting drive cylinder 44 passes through the clearance through hole of the lifting connecting rod 42 and is connected to the clamping assembly 5.

[0041] As can be seen, the push rod structure 6 includes a push-pull cylinder 61 set on the positioning crossbar 43. The output end of the push-pull cylinder 61 is connected to the lifting connecting rod 42 and drives the lifting connecting rod 42 to rise and fall in the lifting slide 41. The bottom of the lifting connecting rod 42 is provided with a separate positioning clamping groove 421, and the adjustable swing assembly 7 is provided with an extension clamping plate 71 corresponding to the separate positioning clamping groove 421.

[0042] Here, the length of the extension clamp 71 is not limited. During the initial adjustment of the clamping depth, the lifting drive cylinder 44 is used to drive the clamping assembly 5 to descend. During the secondary adjustment, the extension clamp 71 in the adjustable swing assembly 7 is continuously lowered by the push-pull cylinder 61, thereby expanding the clamping depth.

[0043] Furthermore, the clamping assembly 5 includes a clamping seat 51 connected to the lifting drive cylinder 44. Both ends of the clamping seat 51 are connected to the adjustable swing assembly 7 via damping hinge shafts 52. The lower end of the clamping seat 51 is symmetrically provided with sliding gear grooves 53. The sliding gear grooves 53 are provided with meshing gear discs 54. The bottom of the gear discs 54 is connected to elastic clamping plates 56 via damping connecting shafts 55. The elastic clamping plates 56 located on both sides of the lower end of the clamping seat 51 are arranged in an inclined symmetrical manner. The elastic clamping plates 56 and the adjustable swing assembly 7 are connected by an arc-shaped top pressure spring 57.

[0044] The elastic clamp 56 can effectively increase the clamping force on the vortex spinning, and can achieve linkage contraction with the swing of the adjustable swing component 7. Together with the adjacent adjustable swing component 7, it can achieve a wider comprehensive clamping and increase the clamping and gripping capacity.

[0045] Furthermore, the adjustable swing assembly 7 includes a clamping frame 72 connected to the damping hinge shaft 52. The clamping frame 72 has strip-shaped adjustment grooves 73 on both sides, and the aforementioned extension clamping plate 71 is inserted into the circumferential inner side of the clamping frame 72. The upper end of the extension clamping plate 71 is provided with a snap-fit ​​cap 711 corresponding to the separate positioning clamping groove 421, and the lower end of the extension clamping plate 71 has an easy insertion part 712. The extension clamping plate 71 is provided with a lifting limit groove 713 corresponding to the strip-shaped adjustment groove 73. The clamping frame 72 is provided with a positioning screw 74 that passes through the strip-shaped adjustment groove 73 and the lifting limit groove 713.

[0046] The positioning height of the positioning screw 74 is not limited and can be set as needed. When the positioning screw 74 is set at the uppermost end of the lifting limit groove 713, the extension length of the extension clamp is shorter. When the positioning screw 74 is set at the lowermost end of the lifting limit groove 713, the extension length of the extension clamp is longer.

[0047] During the secondary adjustment, the push-pull cylinder 61 drives the lifting linkage 42 to descend, causing the snap cap 711 at the upper end of the extension clamp 71 to insert into the corresponding split positioning clamping groove 421 and continuously apply downward pressure, causing the extension clamp 71 to extend downward continuously, thereby allowing the easy insertion part 712 at the lower end of the extension clamp 71 to be inserted into the vortex spinning, thus achieving clamping and positioning.

[0048] Specifically, the upper end of the clamping seat 51 is provided with an electric adjusting tooth groove 8, and the upper surface of the clamping seat 51 is provided with a drive motor 81. The output end of the drive motor 81 is provided with a moving toothed disc 82 that meshes in the electric adjusting tooth groove 8. A movable mounting seat 83 is provided between the drive motor 81 and the electric adjusting tooth groove 8. A pressing push plate 84 is provided on the movable mounting seat 83. The end of the pressing push plate 84 away from the movable mounting seat 83 is provided with a positioning frame groove 85 that acts on the clamping frame 72. The positioning frame groove 85 is engaged with the clamping frame 72, thereby cooperating with the separate positioning clamping groove 421 to position the upper end of the clamping frame 72. The pressing push plate 84 has a receiving groove 86. An auxiliary push plate 88 is connected to the receiving groove 86 through a push spring 87.

[0049] The clamping push plate 84 has two main functions:

[0050] 1. When the extension clamping plate 71 and the elastic clamping plate 56 clamp the vortex spinning stack, a clamping force is applied;

[0051] 2. When it is necessary to adjust the overall clamping width, a driving force is provided to swing the local clamping frame 72 and the extension clamping plate 71 inward.

[0052] Specifically, when the clamping width needs to be adjusted, the lifting drive cylinder 44 lowers the clamping seat 51, while the push-pull cylinder 61 drives the lifting linkage 42 to rise. The lifting linkage 42 drives the extension clamping rod to rise. Due to the limiting effect of the positioning screw 74 and the lifting limit groove 713 on the extension clamping plate 71, the extension clamping rod is limited when the positioning screw 74 is at the bottom of the lifting limit groove 713. The clamping seat 51 and the lifting linkage 42 continue to move away from each other, and the snap cap 711 disengages from the separate positioning clamping groove 421. At this time, the drive motor 81 starts and drives the pressing push plate 84 to continuously apply a pushing force to the clamping frame 72, so that the clamping frame 72 overcomes the force of the damping hinge shaft 52 and swings inward and links the elastic clamping plate 56, thereby realizing the partial storage of the clamping frame 72, and thus achieving the adjustment of the clamping width.

[0053] The spacing between adjacent clamping seats 51 can be set to a short distance or a long distance; the present invention does not limit this.

[0054] When the distance is set to short, in order to prevent the clamping frame 72 from swinging, when two adjacent clamping seats 51 swing, the corresponding extension clamping plates 71 will make contact and repel each other. Therefore, the two adjacent clamping frames 72 adopt a method of one being stationary and the other descending, forming a misalignment and then performing the swinging action.

[0055] When the distance is set to long, the corresponding extension clamps 71 will not collide when the two adjacent clamping frames 72 swing, thus avoiding the conflict of forces.

[0056] More specifically, the mobile lifting platform 1 is provided with a sliding rail 11 at its bottom, and the mobile lifting platform 1 is slidably mounted on the sliding rail 11 via a sliding plate frame 12; a lifting rail 13 is provided on one side of the mobile lifting platform 1, and a lifting slider 14 is provided on one side of the sliding assembly frame 2 and is engaged with the lifting rail 13; the mobile lifting platform 1 is provided with a lifting drive box 15 that can drive the lifting slider 14 to rise and fall, thereby driving the sliding assembly frame 2 to rise and fall on the lifting rail 13; the position sensing component 3 includes an infrared sensing light strip 31 provided on the mobile lifting platform 1, and an infrared sensing module 32 corresponding to the infrared sensing light strip 31 is provided on one side of the sliding assembly frame 2.

[0057] The sliding drive of the mobile lifting platform 1 includes a cylinder and a drag chain plate, and the drive of the lifting drive box 15 includes gear and rack and pinion, gear and chain belt. This invention does not limit the details.

[0058] A gripping method for a linear gripping device for vortex spinning includes the following steps:

[0059] S1, Gripping and gripping preset: Set the gripping width and depth, select the gripping seat 51 used for the gripping position, and set the descent depth and lifting height of the sliding assembly frame 2;

[0060] In this invention, the clamping seat 51 and the extension clamping plate 71 are both equipped with position sensors and pressure sensors, and the cylinders and motors and other driving devices are remotely controlled via a control panel.

[0061] S2, Lowering and gripping eddy current spinning material: Automatically control and adjust the position and gripping depth according to the set parameters, and control the swing of the local clamping frame 72 or the instruction received by the individual clamping seat 51 according to the gripping width;

[0062] S3. After clamping the material, the sliding assembly frame 2 is lifted and slid to the set position for unloading;

[0063] S4. Select either the continuous clamping action or reset, and return to step S1.

[0064] Step S2 specifically includes the following steps:

[0065] S21. The mobile lifting platform 1 slides to the designated position and drives the sliding assembly frame 2 to descend to the set height;

[0066] S22. Select the corresponding clamping seat 51 according to the preset clamping width;

[0067] When it is necessary to expand the gripping width or perform overall clamping, the lifting drive cylinder 44, the push-pull cylinder 61, and the drive motor 81 work together to make the corresponding clamping frame 72 and the extension clamping plate 71 swing toward the inner wall of the clamping seat 51, thereby controlling the clamping width.

[0068] S3. The lifting drive cylinder 44 drives the clamping seat 51 to descend, and the push-pull cylinder 61 drives the extension clamping plate 71 to continue to descend, expanding the clamping depth.

[0069] S4. Stable clamping and increased clamping force are achieved by driving motor 81 to press against clamping frame 72, thus completing the clamping action.

[0070] The elastic clamp 56 is used to increase the pre-clamping force during the clamping process.

[0071] Step S3 specifically includes the following steps:

[0072] S31, the sliding assembly frame 2 is raised to the set height, and the vortex spinning yarn is clamped and raised synchronously;

[0073] S32, The mobile lifting platform 1 slides on the mobile slide rail 11 to the set position;

[0074] S33, the sliding assembly frame 2 descends to the set height, and the vortex spinning yarn is clamped and descends synchronously;

[0075] S34, drive motor 81 retracts, clamping frame 72 relieves force;

[0076] S35, lifting drive cylinder 44, push-pull cylinder 61 drive lifting linkage 42 and clamping seat 51 to reset, the mobile lifting box 1 moves to the initial position, and the sliding assembly frame 2 resets to the initial height.

[0077] In summary, the principle of this embodiment is as follows: the mobile lifting platform 1 moves as a whole through the bottom sliding rail 11 and the slide frame 12, and the sliding assembly frame 2 is raised and lowered by the lifting rail 13 and the lifting drive box 15. The infrared sensing light strip 31 of the position sensing component 3 cooperates with the infrared sensing module 32 to achieve precise positioning. During operation, the gripping width, depth and other parameters are first set and the clamping seat 51 is selected. Then the mobile lifting platform 1 slides to the designated position, and the sliding assembly frame 2 descends to the set height (S21). The clamping seat 51 is selected according to the preset width, and the clamping seat 51 is driven to descend by the lifting drive cylinder 44. Then the extension clamping plate is driven by the push-pull cylinder 61. The clamping depth is increased by lowering the clamping frame 71. Finally, the clamping frame 72 is pressed down by the drive motor 81. The clamping force is increased by the elastic clamping plate 56 and the pressing spring 57 of the clamping component 5 to complete the gripping. After gripping, the sliding assembly frame 2 is raised, the mobile lifting box 1 slides to the unloading position, and then lowers down to unload. Finally, it can choose to continue operation or reset and return. The adjustable swing component 7 adjusts the extension length of the extension clamping plate 71 through the positioning screw 74 and the strip adjustment groove 73. The drive motor 81 and the pressing push plate 84 swing and adjust the clamping frame 72 located in the middle to achieve the purpose of clamping width adjustment, thereby realizing flexible control of gripping amount and clamping force.
