Description

Technical Field

[0001] This invention relates to the field of sock manufacturing technology, and more specifically to a sock stretching board for testing. Background Technology

[0002] During the manufacturing process, socks need to be knitted using a knitting, sewing, and turning machine, and then undergo shaping, cooling, and testing to ensure the quality control of the socks.

[0003] In the prior art, socks are shaped using hot steam. After the shaped socks are cooled, they need to be inspected for holes. However, the non-linear shape of the toe makes it difficult to stretch the sock during hole inspection. Therefore, a sock stretching board for inspection has been proposed. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a sock-stretching board for detection, which solves the problem of the difficulty in stretching the toe area of ​​socks.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] In this invention, a sock-stretching board is used for detecting holes in socks after they have been shaped. The socks include a body, a toe, and a toe seam. The sock-stretching board includes a first sock-feeding component and a second sock-feeding component mounted on the first sock-feeding component.

[0009] The second sock-releasing component is provided with an opening mechanism, which includes a first airbag, a second airbag, and a third airbag;

[0010] The first airbag, the second airbag, and the third airbag are respectively sealed to the second sock insert;

[0011] The spreading mechanism is connected to the first sock-releasing component and the second sock-releasing component through multiple through holes.

[0012] Furthermore, the thickness of the second airbag is less than the thickness of the first airbag, and the thickness of the second airbag is less than the thickness of the third airbag. The second airbag is located at the toe seam.

[0013] Furthermore, a lead screw is installed inside the first stocking release component, and the pusher is threadedly sleeved on the lead screw. The lead screw is rotatably connected to the first stocking release component, and the pusher is threadedly sleeved on the lead screw.

[0014] Furthermore, it also includes a base, on which the first stocking holder is mounted. Sliding members are mounted on both sides of the base, and both sliding members are slidably connected to the base through limiting grooves.

A bidirectional threaded rod is mounted on the base, and the sliding member is threaded onto the bidirectional threaded rod. The two sliding members are symmetrically arranged about the vertical line of the first stocking holder.

[0015] Furthermore, a rack is installed on one of the sliding components near the first sock-holding component, and a cylindrical gear is sleeved on the lead screw. The rack and cylindrical gear are in two states:

[0016] Before the clamping component clamps the sock, the rack and the cylindrical gear do not contact each other;

[0017] After the clamping device holds the sock, the rack and pinion mesh with the cylindrical gear.

[0018] Furthermore, the clamping member is rotatably connected to the sliding member via a rotating shaft, and the clamping member is inclined.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] This application provides a sock-stretching board for detection, which solves the problem of the sock toe being difficult to stretch, and achieves the detection effect of sock toe hole detection.

[0035] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0036] like Figures 1-4 As shown, a sock stretching board is used for detecting holes in socks after they have been shaped. The socks include a body 30, a toe 301, and a toe seam 302. The sock stretching board includes a first sock-releasing member 10 and a second sock-releasing member 101 mounted on the first sock-releasing member 10.

[0037] The second sock-holding component 101 is provided with an opening mechanism, which includes a first airbag 13, a second airbag 131 and a third airbag 14;

[0038] The opening mechanism is connected to the first sock-releasing member 10 and the second sock-releasing member 101 through multiple through holes, and the opening mechanism is highly sealed to the first sock-releasing member 10 and the second sock-releasing member 101.

[0039] The first airbag 13, the second airbag 131 and the third airbag 14 are respectively sealed to the second sock-wearing component 101.

[0040] The stretching mechanism is used to stretch the toe 301 of the sock. By inflating the sock stretching assembly, the inflation of the first airbag 13, the second airbag 131 and the third airbag 14 is controlled. The inflation of the first airbag 13, the second airbag 131 and the third airbag 14 can stretch the toe 301 of the sock that is fitted on the second sock support 101, thereby facilitating the detection of holes in the toe after stretching.

[0041] The thickness of the second airbag 131 is less than the thickness of the first airbag 13, and the thickness of the second airbag 131 is less than the thickness of the third airbag 14.

[0042] The second airbag 131 is located at the toe seam 302;

[0043] By setting the thickness of the second airbag 131 to be thinner than that of the first airbag 13 and the third airbag 14, the expansion degree of the second airbag 131 is greater than that of the first airbag 13 and the third airbag 14. The second airbag 131 expands the seam 302 of the sock toe more obviously, thereby achieving targeted detection of the seam 302 of the sock toe.

[0044] Furthermore, a lead screw 11 is installed inside the first sock-releasing component 10, and the pusher 12 is threaded onto the lead screw 11;

[0045] The lead screw 11 is rotatably connected to the first sock-releasing component 10;

[0046] The lead screw 11 is threaded with a pusher 12, which is slidably connected to the inner wall of the first stocking release member 10 through a sliding groove, and the pusher 12 and the first stocking release member 10 have good sealing performance.

[0047] Furthermore, it also includes a base 20, on which the first sock holder 10 is mounted;

[0048] Sliding members 22 are installed on both sides of the base 20, and both sliding members 22 are slidably connected to the base 20 through limiting grooves;

[0049] The end of the sliding member 22 located outside the first sock-releasing member 10 is equipped with a clamping member 24;

[0050] A bidirectional threaded rod 211 is installed on the base 20, and the sliding member 22 is threadedly sleeved on the bidirectional threaded rod 211.

[0051] The two sliding members 22 are symmetrically arranged about the vertical line of the first stocking member 10;

[0052] The bidirectional threaded rod 211 is driven by a drive motor 21.

[0053] By using the clamping member 24 to hold the sock body 30, after the sock is put on the first sock-releasing member 10 and the second sock-releasing member 101, the sock toe seam 302 is located at the corresponding position of the second airbag 131. Before the stretching mechanism stretches the sock toe, the clamping member 24 holds the sock body 30 to prevent the stretching mechanism from pushing the sock toe 301 upward, thus preventing the sock from moving when the sock toe is stretched, which would make it difficult for the sock toe 301 and the sock toe seam 302 to stretch.

[0054] Furthermore, a rack 23 is installed on one of the sliding members 22 near the first sock-holding member 10, and a cylindrical gear 111 is sleeved on the lead screw 11. The rack 23 and the cylindrical gear 111 are in two states, respectively as follows: Figures 2-3 As shown;

[0055] exist Figure 2 In the state where the clamping member 24 clamps the socks, the rack 23 and the cylindrical gear 111 are not in contact;

[0056] exist Figure 3 In the state where the clamping member 24 clamps the socks, the rack 23 meshes with the cylindrical gear 111.

[0057] By setting the rack 23 and the cylindrical gear 111 in two states, the drive motor 21 provides driving force to the bidirectional threaded rod 211, controlling the clamping member 24 to move towards each other, thereby realizing the clamping member 24 clamping the socks fitted on the first sock-releasing member 10. Since the rack 23 and the cylindrical gear 111 are not in contact at this time, the screw 11 does not rotate before the clamping member 24 clamps the socks, and the spreading mechanism has not yet spread the sock toe 301.

[0058] After the clamping member 24 clamps the socks fitted on the first sock-holding member 10, the rack 23 meshes with the cylindrical gear 111. The further movement of the rack 23 drives the rotation of the lead screw 11, thereby controlling the pusher 12 to drive the spreading mechanism to spread the sock toe 301 and the sock toe seam 302, completing the detection of the sock toe 301 and the sock toe seam 302. This solves the problem in the prior art that during the sock spreading process, the socks are pushed upwards, causing them to run upwards and making it difficult to spread the socks.

[0059] Furthermore, the clamping member 24 is rotatably connected to the sliding member 22 via a rotating shaft 241;

[0060] The clamping member 24 is inclined;

[0061] A torsion spring 242 is sleeved on the outer surface of the rotating shaft 241. Under the action of the torsion spring 242, the clamping member 24 is initially in the following state: Figure 1 As shown.

[0062] By setting the torsion spring 242, the clamping force of the clamping member 24 on the sock is achieved when the high end of the clamping member 24 clamps the sock.

[0063] Furthermore, a sponge block 25 is installed at one end of the clamping member 24 near the first sock-releasing member 10.

[0064] By setting the sponge block 25, after the sock is clamped at the high end of the clamping member 24, the distance that the clamping member 24 can continue to move towards the first sock-releasing member 10 can be further increased, which facilitates the control of the two states of the rack 23 and the cylindrical gear 111.

[0065] After the toe 301 is stretched open and the hole detection is completed, in the initial state, the sock body 30 is put on the first sock-putting piece 10, and the sock toe 301 and the sock toe seam 302 are put on the second sock-putting piece 101. After the sock is put on, the sock toe seam 302 on the sock corresponds to the position of the second airbag 131.

[0066] Furthermore, after the socks are put on, the drive motor 21 controls the bidirectional threaded rod 211 to rotate, controlling the two clamping members 24 to move towards the first sock-putting member 10, until the high end of the inclined clamping member 24 clamps the sock body 30. At this time, the state of the clamping member 24 changes from... Figure 1 Convert to Figure 2 In the state, Figure 1 In this state, there is a certain distance between the clamping member 24 and the first sock-releasing member 10, so that the sock can be put on the first sock-releasing member 10 at the beginning, and the clamping member 24 can be prevented from obstructing the sock-releasing process.

[0067] After the clamping member 24 clamps the sock at its high end, the clamping member 24, through the action of the torsion spring 242, increases the clamping force of the clamping member 24 on the sock body 30. Due to the inclined arrangement of the clamping member 24 and the placement of the sponge block 25, the clamping member 24 can continue to move towards the first sock-releasing member 10, achieving the meshing of the rack 23 and the cylindrical gear 111. This allows the lead screw 11 to drive the pushing member 12 upwards. As the pushing member 12 moves upwards, it inflates the expanding mechanism, facilitating the detection of the sock toe 301 and the sock toe seam 302. At this point, the entire device changes state from... Figure 2 Convert to Figure 3 .

[0068] It should be noted that, under normal conditions, the lead screw 11 can maintain its stability through a return spring, gear, or other conventional self-locking means.

[0069] For example, see below:

[0070] When setting the first sock-covering piece 10, the length of the first sock-covering piece 10 is set to be longer than the length of the regular sock body 30. For example, the length of the first sock-covering piece 10 is set to M1, which is used to cover socks with a length of less than M1 for the sock body 30.

[0071] For example: Suppose that the length of the sock body 30 to be tested is 250mm, and the length of the sock toe 301 is 40mm;

[0072] The length of the first sock piece 10 is set to M1 = 300 mm;

[0073] like Figures 1-4 As shown, from the moment the rack 23 begins to contact the cylindrical gear 111 until the degree of expansion of the opening mechanism satisfies the hole detection of the toe 301 and the seam 302 of the sock, the minimum upward volume V required by the pusher 12 is X in order to achieve the hole detection of the toe 301 and the seam 302 of the sock.

[0074] After the high end of the clamping member 24 contacts the sock body 30 to clamp the sock, the maximum distance Lmax that the rack 23 can move is the horizontal distance from the low end of the inclined clamping member 24 to the center of the rotating shaft 241 and the distance that the sponge block 25 can compress, such as... Figure 4 The horizontal distance from the lower end of the clamping member 24 to the center of the rotating shaft 241 is L1;

[0075] The compressible distance of the sponge block 25 is set to 5 / 6 of the thickness of the sponge block 25. Here, the thickness of the sponge block 25 is set to 12mm, so the compressible distance L2 of the sponge block 25 is 10mm.

[0076] Assuming the length of clamping member 24 is 150mm, the rotating shaft 241 is located at the center of clamping member 24, and the tilt angle of clamping member 24 is 30°, then L1 = 120mm can be obtained;

[0077] We can further obtain Lmax = L1 + L2 = 10 + 120 = 130 mm;

[0078] The number of revolutions of cylindrical gear 111 is C = Lmax / 3.14d, where d is the diameter of cylindrical gear 111;

[0079] The distance L3 that the pusher 12 moves is the pitch D of the lead screw 11 and the number of rotations C of the cylindrical gear 111, i.e., D·C;

[0080] Assuming the diameter of cylindrical gear 111 is 10mm, C = Lmax / 3.14d is approximately 5 revolutions;

[0081] The pitch D of the lead screw 11 is set to 8mm. Therefore, L3 = V / W / N = D·C = 40mm, where W is the width of the inner wall of the first stocking piece 10 and N is the thickness of the inner wall of the first stocking piece 10.

[0082] Setting W = 100mm and N = 5mm, we get V = 20cm. 3 =20ml, of which 20ml is sufficient to achieve the required stretching degree for detecting holes in the toe 301 and the seam 302 of the sock, using the first airbag 13, the second airbag 131 and the third airbag 14.

[0083] In summary, compared with existing technologies, it has the following beneficial effects:

[0084] 1. The stretching mechanism is used to stretch the toe of the sock. By inflating the sock stretching component, the inflation of the first, second, and third airbags is controlled. The inflation of the first, second, and third airbags can stretch the toe of the sock that is fitted onto the second sock piece, thus facilitating the detection of holes in the toe after stretching. At the same time, by setting the thickness of the second airbag to be thinner than that of the first and third airbags, the stretching degree of the second airbag is greater than that of the first and third airbags. The second airbag stretches the seam of the sock toe more obviously, thus enabling targeted detection of the seam of the sock toe.

[0085] 2. By using the clamping device to hold the sock body, after the sock is put on the first and second sock-laying pieces, the toe seam is located in the corresponding position of the second airbag. Before the stretching mechanism stretches the sock toe, the clamping device holds the sock body to prevent the stretching mechanism from pushing the sock toe upward, thus preventing the sock from moving when the sock toe is stretched, which would cause problems with the sock toe and the toe seam stretching.

[0086] 3. By tilting the clamping member and adding the sponge block, after clamping the sock at the high end of the clamping member, the distance that the clamping member can continue to move towards the first sock placement member can be further increased. This facilitates the control of both rack and pinion and cylindrical gear states. In the initial state of the clamping member, there is a certain distance between the clamping member and the first sock placement member, which makes it easier for the sock to be put on the first sock placement member initially. This prevents the clamping member from obstructing the sock putting process and ensures that the clamping member holds the sock before the opening mechanism opens.
