Description

Technical Field

[0001] This utility model belongs to the technical field of automated sock machine equipment, and relates to a sock machine scissor assembly. Background Technology

[0002] The scissor assembly in a sock machine sewing mechanism is a key component, and its performance directly affects the machine's production efficiency and product quality. A traditional sock machine scissor assembly, such as the one disclosed in Chinese patent [Application No.: 202321808699.5], includes a mounting bracket, a lifting cylinder fixed on the bracket, a thread-cutting cylinder mounted on the output end of the lifting cylinder, and a return spring installed between the bottom end of the thread-cutting cylinder and the side wall of the lifting cylinder; scissors for cutting thread are mounted on the thread-cutting cylinder; and the thread-cutting cylinder has an air inlet bend.

[0003] The scissor assembly in the above solution achieves the wire-cutting function to a certain extent, but it has a redundant structure, requires dual cylinders for coordinated control, has a complex air circuit layout, and the spring is prone to relaxation due to long-term shearing vibration, which causes the scissor reset position to deviate. In addition, the scissor blade is directly driven by the cylinder and lacks rigid guiding constraint. Since the piston rod of the cylinder is prone to lateral deviation during the movement, the movement trajectory of the scissor blade is unstable and unevenly worn, which not only affects the accuracy of wire cutting, but may also cause the scissor blade to collide with other components. Utility Model Content

[0004] The purpose of this utility model is to address the above-mentioned problems by providing a sock machine scissor assembly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sock knitting machine scissor assembly includes scissors, the scissors comprising a first blade and a second blade, the first blade and the second blade being connected by a blade hinge, a first linear guide assembly being provided between the handle of the first blade and the scissor base to restrict the first blade to axial movement only, a linear drive unit being provided between the first blade and the scissor base, and an opening and closing guide structure being provided between the first blade and the scissor base to allow the second blade to rotate around the blade hinge to complete the opening and closing of the scissors when the first blade moves linearly along the first linear guide assembly.

[0007] The linear drive unit directly propels the first blade body to move linearly along the first linear guide assembly, eliminating the need for coordinated control of multiple drives and simplifying the structure and layout. The rigid constraint of the first linear guide assembly ensures that the first blade body moves only along a single axis, avoiding the lateral force generated when the traditional cylinder directly drives the scissors, while improving the repeatability and positioning accuracy of the cutting action. The opening and closing guide structure can accurately convert the linear motion of the first blade body into the rotational opening and closing action of the second blade body. The opening and closing angle of the scissors and the cutting stroke can be precisely controlled, which can adapt to different wire thicknesses and cutting strength requirements.

[0008] In the above-mentioned sock machine scissor assembly, the opening and closing guide structure includes an opening and closing guide groove provided on the scissor seat. The central axis of the opening and closing guide groove is inclined to the central axis of the first linear guide assembly. An opening and closing guide slide body is provided on the handle of the second blade body, which passes through the opening and closing guide groove and can move along its length direction.

[0009] The mechanical cooperation between the opening and closing guide groove and the opening and closing guide slide ensures that the opening and closing angle and stroke of each shearing action are completely determined by the geometric parameters of the opening and closing guide groove, thus improving long-term stability. The shearing force is transmitted through the rigid contact between the opening and closing guide groove and the opening and closing guide slide, resulting in high shearing drive efficiency. The simple structure eliminates the need for other complex connecting mechanisms, making it more suitable for the narrow installation space of sock machines.

[0010] In the aforementioned sock machine scissor assembly, the opening and closing guide structure includes an opening and closing guide groove provided in the handle of the second blade body. The central axis of the opening and closing guide groove is inclined to the central axis of the first linear guide assembly. The scissor seat is provided with an opening and closing guide slide body that passes through the opening and closing guide groove and can move along its length direction.

[0011] In the aforementioned sock machine scissor assembly, a straight groove is provided on the inner end of the opening and closing guide groove, and the central axis of the straight groove is parallel to the central axis of the linear drive unit.

[0012] When the opening and closing guide slider of the second cutter body slides in the straight groove, since the straight groove is parallel to the central axis of the linear drive unit, the second cutter body only moves in a straight line synchronously with the first cutter body during this stage and does not rotate. The actual shearing action is triggered only when the opening and closing guide slider enters the opening and closing guide groove, thus avoiding the problem of wire pulling or incomplete shearing caused by premature closure of the blade in the traditional solution.

[0013] In the aforementioned sock machine scissor assembly, the opening and closing guide slide is disposed on the widened extension plate of the handle of the second blade.

[0014] The widened extension plate provides a stable support platform for the opening and closing guide slide body, preventing the sliding trajectory from deviating due to deformation of the second cutter body under high-frequency shearing.

[0015] In the aforementioned sock machine scissor assembly, the first linear guide component includes a first linear guide groove disposed between the handle of the first blade body and / or the scissor seat. A strip-shaped guide slider is provided in the first linear guide groove, and one end of the strip-shaped guide slider is fixed to the handle of the first blade body.

[0016] The first linear guide groove acts as a sliding guide for the strip guide slider, thereby ensuring that the first blade can only move along the first linear guide groove, avoiding the lateral force generated when the traditional cylinder directly drives the scissors, and improving the repeatability and positioning accuracy of the cutting action.

[0017] In the aforementioned sock machine scissor assembly, the strip-shaped guide slider is provided with a reset slider that passes through the scissor seat, and the scissor seat is provided with a reset guide groove that cooperates with the reset slider.

[0018] The reset slider can pull back the strip guide slider to quickly reset the first and second cutter bodies.

[0019] In the aforementioned sock machine scissor assembly, the linear drive unit includes a single-acting propulsion cylinder, the output end of which abuts against the handle of the first blade body; an elastic reset structure for resetting the first blade body after it moves forward is provided between the scissor seat and the handle of the first blade body.

[0020] The output end of the single-acting propulsion cylinder extends to push the first cutter body to move. After the second cutter body completes shearing, the elastic reset structure can reset the first and second cutters body.

[0021] In the aforementioned sock machine scissor assembly, the elastic reset structure includes a reset spring disposed at the bottom of the scissor seat. One end of the reset spring is connected to the lower end of the opening and closing guide slide body, and the other end is connected to the spring fixing post at the bottom of the scissor seat.

[0022] When the opening and closing guide slider moves within the opening and closing guide groove, the return spring is stretched to provide elastic potential energy for reset. After the second cutter completes shearing, the return spring releases energy and pulls the lower end of the opening and closing guide slider to reset the second cutter and the first cutter.

[0023] In the aforementioned sock machine scissor assembly, the blade hinge includes a hinge bolt and a hinge nut. A blade tension adjustment spring is fitted onto the hinge bolt, with one end of the spring abutting against the tail of the hinge bolt and the other end abutting against the second blade. The scissor seat has a positioning plate, which is fixed to the mounting plate of the mounting base by fixing bolts. The mounting plate has bolt positioning holes and arc-shaped adjustment holes. The positioning plate has strip-shaped positioning holes that correspond to the bolt positioning holes and arc-shaped adjustment holes. Fixing bolts are inserted between the strip-shaped positioning holes and the bolt positioning holes and arc-shaped adjustment holes, respectively. The linear drive unit contains a counting signal sensor.

[0024] During operation, the blade tension adjustment spring consistently applies a stable elastic force to the second blade. This elastic force, adjusted by the hinge bolt and hinge nut, precisely controls the friction between the blades, adapting to the shearing needs of yarns of varying thicknesses and materials. The positioning plate can be rotated via the combination of the arc-shaped adjustment hole and the strip-shaped positioning hole, allowing for the rotation adjustment of the shears and accommodating different installation angles. A counting signal sensor tracks the number of drives by the linear drive unit, automatically incrementing the count after each shearing action for real-time monitoring.

[0025] Compared with existing technologies, the advantages of this invention are: 1. It eliminates the need for coordinated control of multiple drives, simplifying the structure and layout. 2. It ensures that the first blade moves only along a single axis, avoiding the lateral force generated when the traditional cylinder directly drives the scissors, while improving the repeatability and positioning accuracy of the cutting action. 3. The opening and closing angle of the scissors and the cutting stroke can be precisely controlled, adapting to different wire thicknesses and cutting strength requirements.

Detailed Implementation

[0032] Example 1

[0033] like Figures 1-4 As shown, a sock knitting machine scissor assembly includes scissors 1, which includes a first blade body 2 and a second blade body 3. The first blade body 2 and the second blade body 3 are connected by a blade body hinge 4. A first linear guide component 6 is provided between the handle of the first blade body 2 and the scissor seat 5, which can restrict the first blade body 2 to move only axially. A linear drive unit 7 is also provided between the first blade body 2 and the scissor seat 5. An opening and closing guide structure 8 is provided between the first blade body 2 and the scissor seat 5, which enables the second blade body 3 to rotate around the blade body hinge 4 to complete the opening and closing of the scissors 1 when the first blade body 2 moves linearly along the first linear guide component 6.

[0034] In this invention, the linear drive unit 7 drives the first blade 2 to move linearly along the first linear guide assembly 6. When the first blade 2 moves, the opening and closing guide structure 8 forces the second blade 3 to rotate around the blade hinge 4, thereby realizing the cutting action of the scissors 1.

[0035] The linear drive unit 7 directly pushes the first cutter body 2 to move linearly along the first linear guide assembly 6, eliminating the need for coordinated control of multiple drives and simplifying the structure and layout. The rigid constraint of the first linear guide assembly 6 ensures that the first cutter body 2 moves only along a single axis, avoiding the lateral force generated when the traditional cylinder directly drives the scissors 1, while improving the repeatability and positioning accuracy of the cutting action. The opening and closing guide structure 8 can accurately convert the linear motion of the first cutter body 2 into the rotational opening and closing action of the second cutter body 3. The opening and closing angle and cutting stroke of the scissors 1 can be precisely controlled, which can adapt to different wire thicknesses and cutting strength requirements.

[0036] Specifically, combining Figures 1-4As shown, the opening and closing guide structure 8 includes an opening and closing guide groove 9 disposed on the scissor seat 5. The central axis of the opening and closing guide groove 9 is inclined to the central axis of the first linear guide assembly 6. An opening and closing guide slide body 10 is disposed on the handle of the second blade body 3, which passes through the opening and closing guide groove 9 and can move along its length direction.

[0037] When the first blade 2 moves linearly along the first linear guide assembly 6, the opening and closing guide slider 10 on the handle of the second blade 3 is forced to move along the trajectory of the opening and closing guide groove 9. Since the central axis of the opening and closing guide groove 9 is inclined to the central axis of the first linear guide assembly 6, the displacement of the opening and closing guide slider 10 in the opening and closing guide groove 9 will be converted into the rotational motion of the second blade 3 around the blade hinge 4 to realize the cutting action of the scissors 1.

[0038] The mechanical cooperation between the opening and closing guide groove 9 and the opening and closing guide slide body 10 ensures that the opening and closing angle and stroke of each shearing action are completely determined by the geometric parameters of the opening and closing guide groove 9, thus improving long-term stability. The shearing force is transmitted through the rigid contact between the opening and closing guide groove 9 and the opening and closing guide slide body 10, resulting in high shearing drive efficiency. The simple structure eliminates the need for other complex connecting mechanisms, making it more suitable for the narrow installation space of sock machines.

[0039] Specifically, combining Figures 2-4 As shown, a straight groove 11 is provided on the inner end of the opening and closing guide groove 9, and the central axis of the straight groove 11 is parallel to the central axis of the linear drive unit 7.

[0040] When the opening and closing guide slide 10 of the second cutter body 3 slides in the straight groove 11, since the straight groove 11 is parallel to the central axis of the linear drive unit 7, the second cutter body 3 only moves in a straight line synchronously with the first cutter body 2 during this stage and does not rotate. The actual cutting action is triggered only when the opening and closing guide slide 10 enters the opening and closing guide groove 9, thus avoiding the problem of wire pulling or incomplete cutting caused by premature closure of the blade in the traditional solution.

[0041] Specifically, combining Figures 1-4 As shown, the opening and closing guide slide body 10 is disposed on the widened extension plate 12 of the handle of the second cutter body 3; the opening and closing guide groove 9 gradually slopes outward from the handle of the first cutter body 2 to the cutter head.

[0042] The widened extension plate 12 provides a stable support platform for the opening and closing guide slide body 10, preventing the second cutter body 3 from deviating from its sliding trajectory due to deformation under force during high-frequency shearing. The opening and closing guide groove 9 can force the opening and closing guide slide body 10 to shift outward, driving the second cutter body 3 to rotate rapidly around the cutter body hinge 4, thereby improving shearing efficiency.

[0043] Specifically, combining Figure 1 , Figure 3 and Figure 4As shown, the first linear guide assembly 6 includes a first linear guide groove 13 disposed between the handle of the first blade body 2 and / or the scissor seat 5. A strip-shaped guide slider 14 is provided in the first linear guide groove 13, and one end of the strip-shaped guide slider 14 is fixed to the handle of the first blade body 2.

[0044] The strip guide slider 14 is slidably connected in the first linear guide groove 13. The first linear guide groove 13 plays a sliding guiding role for the strip guide slider 14, thereby ensuring that the first blade body 2 can only move along the first linear guide groove 13, avoiding the lateral force generated when the traditional cylinder directly drives the scissors 1, and improving the repeatability and positioning accuracy of the cutting action.

[0045] Specifically, combining Figure 1 , Figure 3 and Figure 4 As shown, the strip guide slider 14 is provided with a reset slider 15 that passes through the scissor seat 5, and the scissor seat 5 is provided with a reset guide groove 16 that cooperates with the reset slider 15.

[0046] The first cutter body 2 and the second cutter body 3 can be quickly reset by pulling back the strip guide slider 14 through the reset slider 15.

[0047] Specifically, combining Figure 3 As shown, the linear drive unit 7 includes a single-acting propulsion cylinder 20, the output end of which abuts against the handle of the first blade body 2; an elastic reset structure 17 for resetting the first blade body 2 after it moves forward is provided between the scissor seat 5 and the handle of the first blade body 2. The elastic reset structure 17 includes a reset spring 18 disposed at the bottom of the scissor seat 5. One end of the reset spring 18 is connected to the lower end of the opening and closing guide slide body 10, and the other end is connected to the spring fixing post 19 at the bottom of the scissor seat 5.

[0048] The output end of the single-acting propulsion cylinder 20 extends to push the first cutter body 2 to move. When the opening and closing guide slide body 10 moves in the opening and closing guide groove 9, the reset spring 18 is stretched to provide elastic potential energy for reset. When the second cutter body 3 completes the shearing, the reset spring 18 releases energy and drives the second cutter body 3 and the first cutter body 2 to reset by pulling the lower end of the opening and closing guide slide body 10.

[0049] Specifically, combining Figures 1-4 As shown, the blade hinge 4 includes a hinge bolt 21 and a hinge nut 22. A blade tension adjustment spring 23 is sleeved on the hinge bolt 21. One end of the blade tension adjustment spring 23 abuts against the tail of the hinge bolt 21, and the other end abuts against the second blade 3.

[0050] The output end of the single-acting propulsion cylinder 20 extends to push the first blade 2 to move. During the operation of the scissors 1, the blade tension adjustment spring 23 always applies a stable elastic force to the second blade 3. This elastic force can be precisely controlled by adjusting the hinge bolt 21 and hinge nut 22 to adapt to the cutting needs of yarns of different thicknesses and materials.

[0051] The optimal approach, combined with Figures 1-5 As shown, the scissor seat 5 is provided with a positioning plate 24, which is fixed to the mounting plate 26 of the mounting base 25 by fixing bolts 27; the mounting plate 26 is provided with bolt positioning holes 28 and arc-shaped adjustment holes 29, and the positioning plate 24 is provided with strip-shaped positioning holes 30 that are adapted to the bolt positioning holes 28 and arc-shaped adjustment holes 29. Fixing bolts 27 are respectively inserted between the strip-shaped positioning holes 30 and the bolt positioning holes 28 and arc-shaped adjustment holes 29; the linear drive unit 7 is provided with a counting signal sensor 31.

[0052] By cooperating with the arc-shaped adjustment hole 29 and the strip-shaped positioning hole 30, the positioning plate 24 can be rotated and adjusted, thereby adjusting the rotation of the scissors 1 to adapt to different installation angles; the counting signal sensor 31 can count the number of drives of the linear drive unit 7, and automatically increment the count after each shearing action to achieve real-time monitoring.

[0053] Specifically, combining Figure 1 , Figure 2 and Figure 4 As shown, the first cutter body 2 has a widening seat 32 on the handle, and a connecting seat 33 is provided at one end of the strip guide slider 14. At least one prepositioning post 34 is provided on the connecting seat 33 through which the widening seat 32 passes. The connecting seat 33 and the widening seat 32 are fixed by bolts.

[0054] The pre-positioning post 34 can ensure accurate alignment between the strip guide slider 14 and the tool holder of the first tool body 2, ensuring positioning accuracy, avoiding positional deviations of traditional bolt connections, and enabling rapid installation.

[0055] The working principle of this utility model is as follows: the output end of the single-acting propulsion cylinder 20 extends and pushes the first blade body 2 to move linearly along the first linear guide groove 13. The opening and closing guide sliding body 10 on the handle of the second blade body 3 is forced to move along the trajectory of the opening and closing guide groove 9. The displacement of the opening and closing guide sliding body 10 in the opening and closing guide groove 9 is converted into the rotational motion of the second blade body 3 around the blade body hinge 4 to perform the cutting action of the scissors 1. When the second blade body 3 completes the cutting, the return spring 18 releases energy and pulls the lower end of the opening and closing guide sliding body 10 to drive the second blade body 3 to rotate and return to its original position.

[0056] Example 2

[0057] The structure and working principle of this embodiment are basically the same as those of Embodiment 1. The difference is that the opening and closing guide structure 8 includes an opening and closing guide groove 9 provided in the handle of the second blade body 3. The central axis of the opening and closing guide groove 9 is inclined to the central axis of the first linear guide assembly 6. The scissor seat 5 is provided with an opening and closing guide slide body 10 that passes through the opening and closing guide groove 9 and can move along its length direction.
