A type of integrated knitting and sewing machine for socks

Abstract

This utility model discloses an integrated knitting and sewing machine for socks, including a knitting station and a sewing station. The knitted sock blank is transferred from the knitting station to the sewing station. The sewing station has a downward-opening tubular mechanism into which the sock blank enters from bottom to top. A sock-pressing component is provided between the knitting and sewing stations. This component is a slender rod, rotatably mounted on the machine frame at one axial end. The rotation direction of the pressing rod is vertical and perpendicular to the line connecting the knitting and sewing stations. This utility model facilitates the extraction of the sock blank from the needle cylinder in the knitting station and is suitable for sock sewing machines with a downward-opening tubular mechanism.

Description

Technical Field

[0001] This utility model belongs to the field of knitting machinery technology, specifically relating to sock machines, and in particular to an integrated knitting and sewing machine for socks. Background Technology

[0002] The mainstream sock machine at present is the integrated knitting and sewing machine, which actually combines the sock knitting machine and the sock sewing machine into one. The sock is knitted at one station, and then the sock blank is transferred to another station to complete the sewing.

[0003] A technical problem exists in existing integrated knitting and sewing machines for socks: when the socks are very long, the front end has already entered the tubular mechanism of the sewing machine, while the rear end remains inside the knitting cylinder, which affects subsequent processing steps. To address this, the industry has adopted several technical solutions. For example, CN115613205A discloses a long-tube fabric lifting device, including an installation platform, a screw drive assembly, a fabric pusher, and a sliding mechanism. The installation platform is equipped with the screw drive assembly and the sliding mechanism, and the fabric pusher is mounted on the sliding mechanism. The screw drive assembly is fixedly connected to the sliding mechanism and drives the sliding mechanism to reciprocate the fabric pusher. The disadvantage of this technical solution is that it is only applicable to sock blanks entering the sewing machine from top to bottom, and not to sock blanks entering the tubular mechanism from bottom to top. Another disadvantage is the possibility that when the forces on both sides of the fabric pusher are balanced, the sock blank may get stuck, forming a triangle between the knitting machine, sewing machine, and fabric pusher, preventing it from moving forward or backward. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned defects and provide an integrated knitting and sewing machine for socks that is suitable for sock sewing machines that enter the tubular mechanism from bottom to top.

[0005] The technical solution adopted by this utility model is as follows: a sock knitting and sewing integrated machine includes a sock knitting station and a sock sewing station, wherein the knitted sock blank is transferred from the sock knitting station to the sock sewing station; characterized in that: the sock sewing station has a tubular mechanism with an opening facing downwards, and the sock blank enters the tubular mechanism from bottom to top; a sock pressing component is provided between the sock knitting station and the sock sewing station, the sock pressing component is a slender rod, and is rotatably mounted on the machine frame with one axial end thereon, the rotation direction of the sock pressing rod is vertical and perpendicular to the line connecting the sock knitting station and the sock sewing station.

[0006] Furthermore, the sock-pressing rod is fitted with a movable tube around its periphery, which can roll around the axial direction of the sock-pressing tube.

[0007] The active tube has a smooth surface.

[0008] The usage process of this utility model is as follows: When knitting or sewing socks, the sock-pressing component opens, moving away from the line connecting the knitting and sewing stations; this is the non-working position of the sock-pressing component. During the transfer of the sock blank from the knitting station to the sewing station, one end of the sock blank is in the sewing station while the other end is in the knitting station, meaning the sock blank lies horizontally between the two stations. At this time, the sock-pressing component rotates downwards, pressing down on the sock blank; this is the working position of the sock-pressing component. The sock-pressing component applies pressure to the sock blank, facilitating its extraction from the needle in the knitting station. Since the tubular mechanism of the sewing station is open downwards, the downward pressure on the sock blank does not affect its entry into the tubular mechanism. The rolling movable tube around the sock-pressing bar creates rolling friction between the bar and the sock blank, rather than sliding friction, resulting in lower friction and preventing jamming, thus ensuring smooth extraction of the sock blank. Attached Figure Description

[0009] Figure 1 This is a schematic diagram showing the state of the finished socks according to this utility model.

[0010] Figure 2 , Figure 3 This is a schematic diagram showing the state of the socks after they are finished being knitted and transferred. Detailed Implementation

[0011] See the attached drawings. This utility model has a sock knitting station 1 and a sock sewing station 2. There is a needle cylinder 4 on the sock knitting station, and the socks are knitted inside the needle cylinder to form a sock blank 00.

[0012] Figure 1 In the indicated state, the transfer mechanism 3 hooks onto the head end of the sock blank and remains above the syringe 4, with the end of the sock blank remaining inside the syringe. The pressing component 8 tilts back, avoiding the line connecting the knitting station 1 and the sewing station 2.

[0013] Figure 2 In the state shown, the transfer mechanism 3 moves the hooked head end of the sock blank to the sock sewing station; since the sock blank 00 is relatively long, the end of the sock blank remains in the needle cylinder, so that the sock blank 00 lies horizontally between the sock knitting station 1 and the sock sewing station 2.

[0014] Figure 3 In the indicated state, the sock-pressing component 8, driven by its motor 83, rotates around its axial end 82, causing it to press down on the sock blank 00 and continue pressing downwards. This pressure helps the end of the sock blank to leave the needle cylinder 4, allowing it to enter the tubular mechanism 4 at the sock-sewing station from bottom to top. The sock-pressing component 8 has a movable tube 81 on its periphery that directly contacts the sock blank. Therefore, during the pressing process, the movable tube rolls, preventing jamming.
