[0058] DETAILED DESCRIPTION

[0059] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0060] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0061] The embodiment of the present application provides an expansion device for toe-split socks, which solves the problem that the toe-split part of the toe-split socks is not fully expanded, thereby affecting the shaping effect. The airbag 4 is used to fully expand the toe-split part of the toe-split socks, thereby improving the shaping effect.

[0062] The technical solution in the embodiments of the present application is to solve the above technical problems, and the overall idea is as follows:

[0063] The airbag 4 is inserted into the toe part and inflated so that the toe part can be fully unfolded, thereby facilitating shaping.

[0064] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0065] Example 1

[0066] Reference Figure 1-Figure 7 A toe-opening device for tabi socks comprises a plate body 1, wherein a cavity is formed in the plate body 1;

[0067] an air duct 2, one end of which is in communication with the cavity and the other end of which extends outside the plate body 1, the air duct 2 being used to inflate or extract gas from the cavity;

[0068] A piston 3 is installed in the cavity and is movably sealed with the cavity;

[0069] Several air bags 4 are installed on the piston 3;

[0070] a through hole corresponding to the position of the airbag 4 and communicating with the cavity;

[0071] The blocking block 5 is installed in the cavity and is located on the moving track of the piston 3, and is used to block the piston 3 from moving out of the cavity.

[0072] During the production process, if it is an ordinary sock, it can be directly put on the plate body 1.

[0073] When producing tabi socks, air is inflated into the cavity through air guide tube 2. As the air pressure in the cavity increases, piston 3 is pushed to move, and airbag 4 follows piston 3 and extends out of the cavity. This allows airbag 4 to penetrate the tabi portion of the sock, and air enters airbag 4, causing it to expand, thereby expanding the tabi portion. This allows steam or hot air to more fully contact the sock during shaping, improving shaping efficiency.

[0074] In a new embodiment, the mounting cavity is provided in the piston 3 and communicates with the through hole;

[0075] A movable plate 6 is located in the mounting cavity;

[0076] A plurality of sealing plugs 7 are mounted on the movable plate 6 at positions corresponding to the through holes, and are configured so that the sealing plugs 7 are in contact and sealed with the through holes;

[0077] A guide rod 8 is mounted on the movable plate 6, and the other end of the guide rod 8 extends out of the mounting cavity and into the cavity;

[0078] A fixing block 9 is installed in the cavity;

[0079] A guide hole is formed on the fixing block 9, and the guide rod 8 passes through the guide hole and contacts the inner wall of the guide hole;

[0080] The partition plate 10 is mounted on the guide rod 8 and is used to abut against the fixed block 9 when following the movement of the guide rod 8;

[0081] The push block 20 is installed in the cavity and is located below the partition 10 .

[0082] The through-hole is blocked by the sealing plug 7. This prevents gas from entering the airbag 4 during the ascent of the piston 3. This prevents the airbag 4 from rubbing against the inner wall of the cavity, ensuring the safety of the airbag 4. As the sealing plug 7 rises, it drives the guide rod 8 upward until the movable plate 6 and the fixed block 9 engage. The movable plate 6 and the sealing plug 7 cannot rise any further, while the sealing plug 7 continues to rise. At this point, the airbag 4 has also moved outside the cavity. The sealing plug 7 then separates from the through-hole, allowing airflow to enter the airbag 4, expanding it and widening the bifurcated toe portion.

[0083] The number and size of the airbags 4 can also be designed according to the style of the specific socks. For example, if the number of toe parts is 2 / 3 / 4 / 5, the number of airbags 4 can be set accordingly, and the size of the airbags can also be set according to the size of the toe parts.

[0084] In a new embodiment, the mounting seat 11 is disposed in the through hole;

[0085] A vent hole is provided on the mounting base 11;

[0086] The limiting column 12 is provided on the mounting seat 11 and is offset from the vent hole. The upper end of the limiting column 12 extends into the airbag 4 , and the upper end of the limiting column 12 is provided with a rounded corner.

[0087] The airbag 4 can be clamped by the mounting seat 11 and the limiting column 12 , so that when the piston 3 is received into the cavity, the airbag 4 is prevented from entering the through hole, thereby protecting the safety of the airbag 4 during use.

[0088] In a new embodiment, a damping assembly is installed between the blocking block 5 and the piston 3 to generate resistance when the piston 3 returns to the cavity.

[0089] Through the resistance generated by the damping component, the gas in the cavity, the sealing plug 7 and the airbag 4 will be discharged along the air guide tube 2 during the process of retracting the airbag 4. At this time, the resistance of the damping component and the friction between the sealing plug 7 and the cavity are inconvenient, and the air pressure in the cavity gradually decreases, and the external force on the sealing plug 7 gradually increases. It can be set until the airbag 4 shrinks and does not rub against the inner wall of the cavity when descending, and the air pressure on the sealing plug 7 can push the sealing plug 7 into the cavity.

[0090] In a new embodiment, several of the air bags 4 are configured to increase or decrease in sequence.

[0091] In this way, when putting on the socks, the position of the socks can be adjusted according to the size of the air bag 4 to ensure that the large toe part can penetrate into the large air bag 4, thereby avoiding the situation where some toe parts are not fully opened due to the same size of the air bags 4, while some toe parts are opened too much and the knitting effect of the toe parts is damaged.

[0092] In a new embodiment, it also includes:

[0093] An air filling and deflation device 13, connected to the air guide tube 2, for filling or deflating the cavity;

[0094] The solenoid valve 14 is provided on the air guide pipe 2 .

[0095] The inflation and deflation device 13 can be an air compressor, an air pump or other equipment, which is commonly used in the prior art and will not be described in detail herein. The electromagnetic valve 14 is quickly opened or closed to ensure that the air pressure of the airway tube 2 after inflation or deflation of the cavity is stable.

[0096] In a new embodiment, the damping assembly includes:

[0097] A mounting groove is provided on the lower side wall of the blocking block 5;

[0098] A first magnetic block 15 is disposed in the mounting groove;

[0099] A slot is provided on the upper side wall of the piston 3 and corresponds to the position of the mounting slot;

[0100] The second magnetic block 16 is disposed in the slot and is configured to attract the first magnetic block 15 .

[0101] Through the mutual adsorption of the first magnetic block 15 and the second magnetic block 16, resistance to movement is generated when the piston 3 moves into the cavity, ensuring that the gas in the airbag 4 fully enters the cavity and is sucked away before the piston 3 descends. The magnetic attraction method has a long service life and will not be easily damaged.

[0102] In a new embodiment, the first magnetic block 15 and the second magnetic block 16 are both made of neodymium magnets, and the first magnetic block 15 and the second magnetic block 16 are configured to be in contact with the side wall.

[0103] By providing the neodymium magnet, the magnetic force is stronger, ensuring that more gas in the airbag 4 can be discharged. When the first magnetic block 15 and the second magnetic block 16 contact each other, the force is even greater.

[0104] In a new embodiment, it also includes:

[0105] a limiting member 19 mounted on the movable plate 6 , wherein the height of the limiting member 19 is smaller than the height of the sealing plug 7 ;

[0106] The communication hole is formed on the movable plate 6 .

[0107] The limiting member 19 is restricted so as to be stuck between the movable plate 6 and the piston 3, ensuring that the gas can generate pressure on the piston 3 through the communicating hole, thereby ensuring that the piston 3 can still move smoothly after the movable plate 6 does not move upward.

[0108] Example 2

[0109] Reference Figure 8-Figure 9 , the damping assembly comprises:

[0110] A friction member 17 is mounted on the blocking block 5;

[0111] A plurality of protrusions 18 are distributed on the surface of the friction member 17 and are made of elastic material;

[0112] The friction groove is provided on the piston 3 and corresponds to the position of the friction member 17 , and the protrusion 18 contacts the inner wall of the friction member.

[0113] By setting the friction member 17 and the protrusion 18, friction is generated between the friction groove to ensure that when the piston 3 moves downward, the gas in the airbag 4 can fully enter the cavity and be sucked away. In addition, the length of the friction member 17 can be set to be greater than the first magnetic block 15. In this way, when the piston 3 moves into the cavity, it will move slowly first, ensuring the stability of the piston 3 during movement and also ensuring the safety of the piston 3.

[0114] During actual use of the present invention, after the socks are put on the sock board, if the socks are toe-parted socks, air can be inflated into the cavity through the air guide tube 2. The increased air pressure in the cavity can push the piston 3 to move, driving the airbag 4 to move, so that the airbag 4 enters the toe-parted part. At the same time, the airbag 4 expands and can lift the toe-parted part.

[0115] During the movement of the piston 3, the movable plate 6, the guide rod 8 and the partition 10 can be pushed to move, and under the restriction of the fixed block 9, the piston 3 can move stably along the movement trajectory of the piston 3. During the movement, the sealing plug 7 and the through hole are sealed, and the airflow will not enter the airbag 4, ensuring that the airbag 4 will not rub against the inner wall of the cavity. After the fixed block 9 contacts the partition 10, the movable plate 6 and the sealing plug 7 can no longer move. Under the action of the limiter 19, the gas can enter the area around the limiter 19 through the connecting hole, continue to generate pressure on the piston 3, push the piston 3 to move, and separate the sealing plug 7 and the through hole, so that the airflow can enter the airbag 4, causing the airbag 4 to expand. At this time, the airbag 4 is already in the toe part.

[0116] After the inspection or shaping is completed, the gas is extracted from the cavity, and the air pressure in the cavity gradually decreases. Under the resistance of the damping component, the gas in the airbag 4 fully enters the cavity. Only then will the external pressure push the piston 3 into the cavity or only move a very short distance, ensuring that the airbag 4 does not rub against the inner wall of the cavity.

[0117] Under the action of the air pressure difference between the outside and the cavity, the piston 3 is pushed to move into the cavity. At the same time, the movable plate 6, the sealing plug 7 and the guide rod 8 move with the piston 3 until the push block 20 contacts the partition 10. The piston 3 continues to move downward, and the sealing plug 7 does not move downward. In this way, the sealing plug 7 can gradually enter the through hole and jam the position of the through hole, ensuring that the next time the five-toed socks are tested, the airbag 4 will not expand until it extends out of the plate body 1.

[0118] In summary, compared with the existing technology, the present invention has the following beneficial effects:

[0119] 1. By configuring the airbag 4 and piston 3, the plate 1 can not only stretch and shape ordinary socks, but also shape tabi socks. This eliminates the need to purchase separate sock plates, saving costs. Furthermore, the tabi sock application process is automated, making it quick and convenient.

[0120] 2. When putting on the split toe socks, the split toe part can be quickly and fully opened to present a three-dimensional shape, thereby improving the quality of shaping and thus improving the processing quality of the split toe socks.
