Description

Technical Field

[0001] This invention relates to the field of boat socks, and in particular to a boat sock, its manufacturing method, and apparatus. Background Technology

[0002] Boat socks are a type of ultra-short, low-cut sock. They are named "boat socks" because their shape resembles a boat (the curved outline fits the ankle and the length reaches no more than the ankle). They are also called "ankle socks," "boat-shaped socks," or "ultra-short socks" because they reach the ankle.

[0003] Like other socks, most boat socks on the market are knitted or machine-knitted products. Socks are typical knitted products, just like knitting sweaters. Baidu Wenku mentions that "socks belong to weft-knitted products, and crochet hooks are the main tool for completing the knitting process." Due to their functional requirements (elasticity, fit) and production process characteristics, boat socks are almost always knitted or machine-knitted. Boat socks belong to weft-knitted fabrics (the mainstream technology for socks). Their production process relies on knitting machines or hand-knitting needles / crochet hooks, using the circular knitting of yarn to form a three-dimensional structure, meeting the elastic wrapping needs of the feet. Machine knitting is the main production method for boat socks; using fully computerized knitting machines, various sizes of boat socks can be produced efficiently. Some handmade boat socks are knitted using knitting needles or crochet hooks, which is a sub-category of knitting.

[0004] There is demand for non-knitted or non-woven boat socks. Summary of the Invention

Detailed Implementation

[0020] Example 1: like Figure 1 As shown: This embodiment is an apparatus for manufacturing boat socks. It uses a cut piece extrusion method to form boat socks. Compared to boat socks currently manufactured using knitting or weaving methods, using a cut piece to manufacture boat socks represents a new approach. Boat socks formed from a single cut piece are integrally molded, just like knitted or woven boat socks, eliminating the need for sewing. This fills a market gap where boat socks are not manufactured from a single piece of fabric through extrusion. The boat sock manufacturing process includes two types of equipment: one is a cutter for the fabric pieces, which can be garment factory cutting equipment or other fabric cutting equipment; the other is an extrusion device, which is not yet available in the industry, such as... Figure 1 As shown, the extrusion device 1000 includes a die device and a cut piece supply device 1100.

[0021] In this embodiment, according to the preparation method of this embodiment, firstly, the fabric is cut into pieces to prepare boat socks using ordinary cutting equipment; then, the pieces are wrapped around the inner mold 1310 using the piece supply device 1100 in the mold device; then, the outer mold 1210 is used to press the inner mold 1310, so that the pieces are pressed into the inner mold 1310 to form a boat sock.

[0022] like Figure 1As shown, the cut piece supply device 1100 is mounted on the support of the extrusion device 1000. The cut piece supply device 1100 includes a pressure plate 1110 and a baffle 1120 for clamping the cut pieces. Both the pressure plate 1110 and the baffle 1120 are flat plates, stacked one on top of the other. Foot-shaped through holes are provided at the same position in the middle of the pressure plate 1110 and the baffle 1120. These through holes allow the inner mold 1310, driven by the inner mold movement device 1320, to press the cut piece against the back of the baffle 1120. According to the design, the cut piece is a square piece of fabric. Through a production line or other conveying device, the cut piece is transferred from the outlet of the cutting equipment to between the pressure plate 1110 and the baffle 1120, covering the foot-shaped through hole. Thus, the pressure plate 1110 and the baffle 1120 clamp the cut piece in the middle, and the cut piece itself can be seen through the foot-shaped through hole. In this embodiment, the pressure plate 1110 and the baffle 1120 are arranged in the middle of the support of the extrusion device 1000. According to the timing control of the central processing unit of the equipment, the pressure plate 1110 and the baffle 1120 are separated, and the cut piece is placed between the pressure plate 1110 and the baffle 1120.

[0023] The mold device includes an inner mold 1310 wrapped with cut pieces supplied by a cut piece supply device 1100 and an inner mold movement device 1320. The cut pieces wrapped in the inner mold 1310 are extruded and molded into a sock by pressing from the outside of the inner mold 1310 towards the inner mold 1310, and the outer mold movement device 1220 is also included.

[0024] In this embodiment, the inner mold 1310 needs to pass through the foot-shaped through hole in the middle of the pressure plate 1110 and the foot-shaped through hole in the middle of the baffle 1120. The outer mold 1210 and the outer mold movement device 1220 are installed on the back of the baffle 1120. The pressure plate 1220 presses the cut piece upward and is blocked by the baffle 1120. The pressure plate 1220 is below and the baffle 1120 is above. Therefore, the back of the baffle 1120 is a horizontal platform facing upward, which can facilitate the installation of the outer mold 1210 and the outer mold movement device 1220. The inner mold 1310 passes through the pressure plate 1110 and the baffle 1120 from below the pressure plate 1220 and enters the back of the baffle 1120, in the middle of the outer mold 1210. In practice, in some other embodiments, the pressure plate 1110 can be installed above the baffle 1120, i.e., the pressure plate 1110 is on top and the baffle 1120 is below. The inner mold 1310 is driven by the inner mold moving device 1320 to pass through the pressure plate 1110 and the baffle 1120 from above, while the outer mold 1210 is still installed on the back of the baffle 1120. The outer mold 1210 is supported by the support of the extrusion device 1000, and the top surface of the outer mold 1210 is attached to the back of the baffle 1120. In this way, whether the pressure plate 1110 or the inner mold 1310 moves downward, the cut piece is placed into the baffle 1120. However, in this embodiment, although the pressure plate 1110 and the inner mold 1310 move upward, and the cut piece is also placed on the pressure plate 1100, the back of the baffle 1120 provides a flat mounting surface for the outer mold 1210.

[0025] In this embodiment, the foot-shaped through hole between the pressure plate 1110 and the baffle 1120 is used for the inner mold 1310 to pass through and for determining the size of the sock opening. The inner mold 1310 cannot pass directly through this foot-shaped through hole. Therefore, in this embodiment, as... Figure 5 , 6 As shown in Figures 7 and 8, the inner mold 1310 includes a hind foot 1311, a forefoot 1313, a left midfoot 1312, and a right midfoot 1314. Under the action of the inner mold motion device 1320, the hind foot 1311, forefoot 1313, left midfoot 1312, and right midfoot 1314 come together to form a complete foot. The inner mold motion device 1320 includes a heel up-and-down motion mechanism 1321 that drives the hind foot 1311 and forefoot 1313 to move up and down respectively; a heel length adjustment mechanism 1322 that drives the hind foot 1311 and forefoot 1313 to move closer to or further away from each other respectively; a foot up-and-down motion mechanism 1323 that drives the left midfoot 1312 and right midfoot 1314 to move up and down respectively; and a foot width adjustment mechanism 1324 that drives the left midfoot 1312 and right midfoot 1314 to move closer to or further away from each other respectively.

[0026] If the hind foot 1311, forefoot 1313, left midfoot 1312, and right midfoot 1314 are assembled together, the volume will be too large to pass through the foot-shaped through hole. Therefore, the inner mold 1310 is divided into the above four parts, and the midfoot is inserted between the forefoot 1311 and the forefoot 1313. In this way, the inner mold motion device 1320 needs to have independent heel up-and-down motion mechanism 1321 and foot up-and-down motion mechanism 1323 to drive the forefoot 1311 and the forefoot 1313 up-and-down motion, as well as the left midfoot 1312 and the right midfoot 1314 up-and-down motion respectively. The hind foot 1311 and forefoot 1313, along with the left midfoot 1312 and right midfoot 1314, pass through the foot-shaped through hole at different times. Generally, in this embodiment, the foot up-and-down movement mechanism 1323 first drives the left midfoot 1312 and right midfoot 1314 downwards, away from the forefoot 1311 and forefoot 1313. Then, driven by the heel length adjustment mechanism 1322, the forefoot 1311 and forefoot 1313 move closer to each other. After they come together, the heel up-and-down movement mechanism 1321 drives the hind foot 1311 and forefoot 1313 to move towards each other. The foot part 1311 and the forefoot part 1313 are pushed upward from the foot-shaped through hole. Since the cut piece covers the foot-shaped through hole, it also enters the back of the baffle 1120 through the foot-shaped through hole. Since the edge of the cut piece is pressed by the pressure plate 1110 and the baffle 1120, the cut piece is tightly wrapped around the close-approaching back foot part 1311 and forefoot part 1313. Then, driven by the heel length adjustment mechanism 1322, the back foot part 1311 and forefoot part 1313 move away from each other, so that the length of the boat sock reaches the designed length. Next, under the action of the foot width adjustment mechanism 1324, the left middle foot 1312 and the right middle foot 1314 move closer to each other. After coming together, under the action of the foot up-down movement mechanism 1323, the left middle foot 1312 and the right middle foot 1314 pass upward through the foot-shaped through hole and reach the middle of the rear foot 1311 and the front foot 1313. Then, under the action of the foot width adjustment mechanism 1324, the left middle foot 1312 and the right middle foot 1314 move away from each other, separating to the designed distance, so that the outer panels of the left middle foot 1312 and the right middle foot 1314 are taut. In practice, at this time, there is a gap between the left middle foot 1312 and the right middle foot 1314. Figure 5As shown. Furthermore, depending on the length of the boat sock, in this embodiment, the height of the heel portion 1311, the left midfoot portion 1312, and the right midfoot portion 1314 only needs to be higher than the ankle, while the thickness of the forefoot portion 1313 only needs to be equal to the height of a normal foot. Thus, when the stretched fabric piece is wrapped around the inner mold 1310, its length is determined. At this time, the edge of the fabric piece is still pressed between the pressure plate 1110 and the baffle 1120. In this embodiment, because a foot-shaped through-hole 1111, smaller than the inner mold 1310, is used for the inner mold 1310 to pass through, the fabric piece can be tightly wrapped around the inner mold 1310. The foot-shaped through-hole 1111 is shown in [reference needed]. Figure 9 As shown.

[0027] Next, the outer mold 1211 presses the cut piece from around the inner mold 1310 to form the shape of a boat sock, as shown. Figure 2 , 3 As shown in Figure 4: The outer mold 1210 is disposed around the foot-shaped through hole on the back of the baffle 1120. The outer mold 1210 includes a rear outer mold 1211 that mates with the rear foot 1311, a front outer mold 1213 that mates with the front foot 1313, a left outer mold 1212 that mates with the left midfoot 1312, and a right outer mold 1214 that mates with the right midfoot 1314. The outer mold movement device 1220 is installed on the back of the baffle 1120 and drives the rear outer mold 1211, the front outer mold 1213, the left outer mold 1212, and the right outer mold 1214 to move toward the inner mold 1310. The rear outer mold 1211, the front outer mold 1213, the left outer mold 1212, and the right outer mold 1214 move toward the inner mold 1310 from around the inner mold 1310, so that the cut pieces between the outer mold 1211 and the inner mold 1310 are squeezed to form a boat sock.

[0028] In this embodiment, the heel up-and-down movement mechanism 1321, the heel length adjustment mechanism 1322, the foot up-and-down movement mechanism 1323, and the foot width adjustment mechanism 1324 all require power. In practice, there are many power devices that drive the inner mold 1310 to move. In this embodiment, the heel up-and-down movement mechanism 1321 and the foot up-and-down movement mechanism 1323 are powered by cylinders, each using two cylinders. The rear foot 1311, front foot 1313, left middle foot 1312, and right middle foot 1314 of the inner mold 1310 are each driven to move up and down by one cylinder. The push rod of each cylinder is fixed. Under the control of the host, each cylinder drives its respective inner mold part to move. The heel length adjustment mechanism 1322 adjusts the relative position between two cylinders in the hind foot 1311 and the forefoot 1313. The foot width adjustment mechanism 1324 adjusts the relative position between two cylinders in the left midfoot 1312 and the right midfoot 1314. This can also be achieved using a power source such as a motor. In this embodiment, cylinders are also used. The cylinder in the hind foot 1311 is fixed to the cylinder's push rod, while the cylinder in the forefoot 1313 is fixed to the cylinder body. This allows the distance between the hind foot 1311 and the forefoot 1313 to be adjusted. Similarly, a single cylinder is used to adjust the distance between the cylinders in the left midfoot 1312 and the right midfoot 1314. In this embodiment, the outer mold motion device 1220 can also be implemented using a cylinder. The rear outer mold 1211, the front outer mold 1213, the left outer mold 1212, and the right outer mold 1214 are each driven by a cylinder, and the cylinder body can be fixed to the back of the baffle.

[0029] In this embodiment, a heating device 1380 is also provided inside the inner mold 1310. In practice, a heating device can also be provided in the outer mold 1210. When the outer mold 1210 presses against the inner mold 1310, the cut piece is heated, which can make the cut piece form faster and less prone to deformation after forming. The heating device 1380 can be a heating tube or heating wire implanted in the inner or outer mold and connected to an external power source. Generally, mains power is used, which allows for higher power and faster heating. Of course, direct current can also be used. By controlling the DC voltage of the power supply as required, the heating temperature can be controlled. In addition, depending on the properties of the materials used for the cut pieces, such as using malleable materials like nylon, the temperature of these heating devices can be controlled. For example, the temperature of the left midfoot 1312, right midfoot 1314, and heel 1312 can be controlled to be higher, or the power of the heating devices inside the front outer mold 1213, left outer mold 1212, and right outer mold 1214 can be controlled to be higher, so that the cut pieces outside the left midfoot 1312, right midfoot 1314, and heel 1312 can be made thicker at the heel of the boat sock.
