Description

Technical Field

[0001] The utility model relates to the technical field of hosiery knitting machine equipment, in particular to a zero position alignment structure of a hosiery knitting machine. Background Art

[0002] The existing hosiery knitting machine consists of a machine head, a cap cover, and a large plate. The machine head is connected to the half plate. A needle groove is provided on the half plate, and a needle cylinder is provided on the large plate. The half plate is located above the needle cylinder. When the hosiery knitting machine is working, zero-position knitting can be achieved only after the needle groove and the needle cylinder are aligned. During the hosiery knitting process, when the socks are knitted and the toe sewing step is entered, the swing arm will shift to grab the socks. At this time, the cap cover and the machine head need to be lifted as a whole. When changing the yarn, the machine head needs to be lifted to facilitate the yarn to pass through the cap cover. When the machine head is lifted and then lowered, since the needle groove of the half plate is small, if it and the needle cylinder are not zero-aligned, the hosiery knitting machine will not work. Therefore, there is an urgent need for a hosiery knitting machine that can quickly and accurately achieve zero-position alignment between the needle cylinder on the large plate and the needle groove on the half plate. Utility Model Content

[0003] In view of this, the present invention aims to provide a zero-position alignment structure for a hosiery knitting machine to solve the problem in the prior art that when the machine head is raised and then lowered, the hosiery knitting machine will not work if the needle groove of the half disc is not aligned with the needle cylinder due to its small size.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0005] A zero-position alignment structure of a hosiery knitting machine comprises a machine head and a half disk. The machine head comprises a first drive assembly connected to the half disk, and the first drive assembly is connected to a first rotating part via a zero-position alignment assembly.

[0006] By setting a zero position alignment component, under the joint action of the first driving component and the first rotating part, zero position alignment is achieved quickly and accurately, so that the needle groove on the half disk and the needle cylinder on the large disk are aligned at zero position, and the hosiery knitting machine knits socks from zero position.

[0007] Furthermore, the zero-position alignment assembly includes a first alignment member and a second alignment member, the first alignment member is connected to the first rotating part, and the second alignment member is connected to the first driving assembly.

[0008] Furthermore, a first groove is provided in the first alignment member, an elastic member and a key are provided in the first groove, the elastic member is connected to the key, and a second groove is provided in the second alignment member. During zero-position alignment, the key penetrates from the first groove into the second groove under the action of the elastic member.

[0009] By setting the first groove, the second groove, the key and the elastic part, the first alignment part is rotated by the first rotating part. When the first groove and the second groove are aligned, the key in the first groove can quickly and accurately penetrate into the second groove under the action of the elastic part to achieve zero-position alignment. At this time, the first rotating part drives the zero-position alignment component, the second rotating part, the third rotating part and the fourth rotating part to rotate, thereby achieving the alignment of the needle groove and the syringe of the half disk connected to the fourth rotating part.

[0010] Furthermore, the first alignment member includes a main body ring, a connecting ring, and a gasket. The main body ring is connected to the connecting ring, and the gasket is connected to the main body ring. The gasket is located on the circumference of the connecting ring and is connected to the main body ring. This arrangement ensures the stability of the first alignment member connection and the alignment efficiency of the needle groove and the syringe.

[0011] Furthermore, one end of the elastic member is located on the gasket, and the other end of the elastic member is connected to the key.

[0012] This arrangement enables the key to have a vertical force, so that during zero alignment, the key can quickly penetrate into the second groove, thereby improving the efficiency of zero alignment.

[0013] Furthermore, the zero-position alignment assembly further includes a fixing member, which is fixed to the outer periphery of the first alignment member and / or the second alignment member.

[0014] This arrangement can improve the stability of the key and prevent the key from being separated from the first groove and the second groove.

[0015] Furthermore, a first through hole is provided on the fixing member, and a limiting column is provided on the key. The limiting column is inserted into the first through hole, and the limiting column can move in the first through hole.

[0016] In this setting, the fixing part is fixed and stationary, and zero-position alignment is achieved by moving the limiting column from one end to the other end in the first through hole. That is, when misaligned, when the key is squeezed by the second alignment part, the limiting column is located at the lower end of the first through hole. When aligned, the end of the key away from the elastic part penetrates into the second groove, and the limiting column moves upward and contacts the upper end of the second through hole.

[0017] Furthermore, the first driving assembly includes a second rotating part, a third rotating part, and a fourth rotating part that are connected in sequence, the fourth rotating part is connected to the half disk, and the second rotating part is connected to the first rotating part through a zero position alignment assembly.

[0018] Furthermore, the end of the second rotating part away from the nose passes through the second alignment member and extends into the first alignment member, the end of the first rotating part close to the nose extends into the first alignment member, and the first rotating part and the second rotating part do not contact each other.

[0019] Furthermore, the second rotating part, the third rotating part, and the fourth rotating part are all rotationally connected through gears, and the first rotating part is connected to a motor.

[0020] Compared with the prior art, the zero-position alignment structure of a hosiery knitting machine described in the present invention has the following advantages:

[0021] 1) The utility model provides a zero-position alignment component, which realizes zero-position alignment under the joint action of the first driving component and the first rotating part, so that the needle groove on the half disk and the needle cylinder on the large disk are aligned at zero position, and the hosiery knitting machine knits socks from the zero position;

[0022] 2) The utility model is provided with a first groove, a second groove, a key, and an elastic member. The first rotating part rotates the first alignment member. When the first groove and the second groove are aligned, the key in the first groove can quickly penetrate into the second groove under the action of the elastic member to achieve zero-position alignment. At this time, the first rotating part drives the zero-position alignment component, the second rotating part, the third rotating part, and the fourth rotating part to rotate, thereby achieving alignment between the needle groove and the syringe of the half disk connected to the fourth rotating part;

[0023] 3) The utility model connects the elastic member to the gasket, and the elastic member is connected to the key; the key has a vertical force, and when zero alignment is performed, the key can quickly penetrate into the second groove, thereby improving the efficiency of zero alignment.

[0032] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. In addition, a brief description is provided of the directions or positions involved in the following specific embodiments: the directions or positions indicated by "up," "down," "left," "right," "front," and "back" mentioned in the embodiments refer to the directions or positions shown in the accompanying drawings.

The machine head 1 is connected to the half plate 5, and the machine head 1 is connected to the cap cover 2. The support portion 3 is arranged on the large plate 4, and the half plate 5 is located above the sleeve 6. The sleeve 6 is connected with a needle cylinder. The machine head 1 comprises a first drive assembly, and the first drive assembly is connected to the half plate 5. The first drive assembly is connected to the first rotating part 10 via a zero-position alignment assembly 50. Under the joint action of the first drive assembly, the zero-position alignment assembly, and the first rotating part, zero-position alignment is achieved, so that the needle groove on the half plate and the needle cylinder on the large plate are aligned at zero position, and the hosiery knitting machine knits socks from zero position. The structure of the half plate, the structure of the large plate, the connection between the half plate and the machine head, the structure of the large plate, the connection between the large plate and the needle cylinder, etc. in the utility model are all prior art and will not be introduced in detail here.

[0034] Specifically, the zero-position alignment assembly 50 includes a first alignment member 51 and a second alignment member 52 . The first alignment member 51 is connected to the first rotating portion 10 , and the second alignment member 52 is connected to the first driving assembly.

[0035] More specifically, the second alignment member 52 is located at the upper end of the first alignment member 51, the end of the first drive assembly away from the machine head 1 passes through the second alignment member 52 and extends into the first alignment member 51, the end of the first rotating part 10 close to the machine head 1 extends into the first alignment member 51, and the first drive assembly and the first rotating part are not in direct contact. This arrangement facilitates lifting and lowering the machine head.

[0036] More specifically, a first groove 5111 is provided in the first alignment member 51, and an elastic member 514 and a key 515 are provided in the first groove 5111. The elastic member 514 is connected to the key 515, and a second groove 521 is provided in the second alignment member 52. When not aligned, the key is pressed by the second alignment member 52 under the action of the elastic member. When alignment is required, the first alignment member 51 is rotated by the first rotating part. When the first groove and the second groove are aligned, the key in the first groove can penetrate into the second groove under the action of the elastic member to achieve zero-position alignment. At this time, the first rotating part drives the zero-position alignment assembly and the first drive assembly to rotate, thereby realizing the operation of the half disk and the syringe connected to the first drive assembly.

[0037] Preferably, the elastic member is a spring.

[0038] More specifically, the first alignment member 51 includes a main body ring 511, a connecting ring 512, and a gasket 513. The main body ring 511 is connected to the connecting ring 512, and the gasket is located around the connecting ring and connected to the main body ring. This arrangement ensures the stability of the first alignment member connection and the efficient alignment of the needle groove and the syringe.

[0039] More specifically, the diameter of the main ring 511 is larger than that of the connecting ring 512. This arrangement improves the connection reliability between the first rotating portion and the first alignment member. The main ring 511 is located above the connecting ring 512. The gasket 513 is connected to the main ring 511 and located at its lower end. The first groove is formed by the main ring and the gasket. One end of the elastic member is located on the gasket, and the other end is connected to the key. This arrangement imparts a vertical force to the key, allowing it to quickly penetrate into the second groove during zero alignment, improving zero alignment efficiency.

[0040] More specifically, the width of the second groove gradually decreases from bottom to top. This setting limits the key and prevents the key from popping out of the second groove.

[0041] Preferably, the second alignment member 52 is a circular ring structure.

[0042] More specifically, the zero alignment assembly 50 further includes a fixing member 53, which is fixed to the outer periphery of the first alignment member 51 and / or the second alignment member 52.

[0043] More specifically, the fixing member 53 is provided with a first through-hole 531, which has a playground runway-like structure. The key 515 is provided with a limiting post 5151, which is inserted into the first through-hole 531 and is movable within the first through-hole. In this arrangement, the fixing member is stationary, and zero-position alignment is achieved by moving the limiting post from one end within the first through-hole to the other. That is, when misaligned, the key is squeezed by the second alignment member, and the limiting post is located at the lower end of the first through-hole. When aligned, the end of the key away from the elastic member extends into the second groove, causing the limiting post to move upward and contact the upper end of the second through-hole.

[0044] Preferably, the fixing member 53 is a circular ring structure.
