Description

Technical Field

[0001] This utility model relates to the field of warp knitting machine technology, and in particular to a needle bed support and cradle connection structure. Background Technology

[0002] A warp knitting machine is a textile machine specifically designed for producing knitted fabrics. It forms fabric by arranging yarns longitudinally (warp direction) and using a series of needles and guide bars (also called yarn guides). Warp knitting is widely used in clothing, home décor, and industrial textiles. The needle bed support and cradle are crucial components of the warp knitting machine, supporting and guiding the needle bed to ensure its stable and precise position during high-speed operation. This allows the needle bed to move smoothly back and forth during machine operation, thus enabling the knitting process. In the warp knitting machine structure, the needle bed cradle is mounted on a central swing shaft. The support and cradle are slidably connected in a straight line. Two different drive shafts drive the central swing shaft and support to reciprocate, and the central swing shaft then drives the cradle to swing, achieving the basic knitting function. This structure has become a mature and widely used feature in warp knitting machines. However, due to the linear sliding of the bracket relative to the cradle, the connecting parts, which are intermediate connecting structures, will experience axial displacement after long-term use during high-frequency reciprocating motion. This will affect the relative movement of the cradle in the same direction, thus affecting the normal use of the machine. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a connection structure for a needle bed support and a cradle, which limits the axial movement of the connecting parts used for linear sliding connection between the support and the cradle, reduces the risk of axial movement of the connecting parts, avoids interference with the normal movement of the cradle, and improves the stability of the warp knitting machine.

[0004] The technical solution to achieve the purpose of this utility model is:

[0005] A needle bed support and cradle connection structure includes a needle bed support, a connector, and a needle bed cradle. The connector is provided in pairs, including a body and a movable part that are slidably connected in a straight direction. A pair of parallel needle bed guide posts are fixedly connected to the needle bed support. The two needle bed guide posts respectively penetrate the body of the corresponding connector and are interference-fitted with the body. The needle bed cradle is fixedly connected to the movable part. Springs are provided at both ends of the connector and fitted on the corresponding needle bed guide posts. The two ends of the springs respectively abut against the ends of the needle bed guide posts and the body of the connector, so that the two ends of the body of the connector are always subject to axial constraint force.

[0006] Furthermore, the end of the spring away from the connector is provided with a shock-absorbing washer coaxially fixedly sleeved on the needle bed guide post and abuts against the shock-absorbing washer.

[0007] Furthermore, the connecting component is a linear bearing.

[0008] Furthermore, the front side of the needle bed cradle is provided with a pair of integrally formed mounting sleeves, the needle bed bracket is provided with mounting holes corresponding to the mounting sleeves, the top of the needle bed guide post is fixedly inserted into the mounting hole, the bottom extends to the lower end of the mounting sleeve, the connector is provided inside the mounting sleeve, and the movable part is fixedly connected to the mounting sleeve.

[0009] Furthermore, the outer peripheral surface of the mounting sleeve is provided with an oil nozzle for connecting the connector.

[0010] Furthermore, the bottom of the mounting sleeve is provided with an oil receiving box that is spaced and fitted onto the lower end of the needle bed guide post.

[0011] By adopting the above technical solution, this utility model has the following beneficial effects:

[0012] (1) This utility model provides springs sleeved on the needle bed guide post at both ends of the connector used to connect the needle bed bracket and the needle bed cradle. The two springs continuously apply an axial force toward the center of the needle bed guide post to both ends of the connector body, thereby limiting the axial movement of the body and preventing circumferential displacement of the body after long-term use, which would interfere with the normal movement of the cradle. At the same time, it can also play a certain role in shock absorption during the relative reciprocating motion of the cradle and the bracket, thereby improving the stability of the warp knitting machine.

[0013] (2) This utility model adds a shock-absorbing washer at the end of the spring away from the connecting part, which eliminates the direct impact that may occur between the cradle and the bracket in relative reciprocating motion. When used in conjunction with the spring, it greatly improves the service life of the entire component while reducing noise.

[0014] (3) This utility model uses linear bearings as connecting parts, which has a simple structure, is easy to install, can be used for high-speed reciprocating motion, and has a longer service life.

[0015] (4) By setting an oil nozzle, this utility model facilitates the addition of lubricating grease to the internal connecting parts, thereby further improving the service life.

[0016] (5) By setting up an oil collection box, this utility model avoids excess oil dripping and contaminating the fabric being processed. Attached Figure Description

[0017] To make the content of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings, wherein:

[0021] 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.

[0022] (Example 1)

[0023] like Figure 1 The needle bed support and cradle connection structure shown includes a needle bed support 1, a connector 2, a needle bed cradle 3, and needle bed guide posts 4. Each connector 2 and needle bed guide post 4 is provided in pairs. The connector 2 includes a body and a movable part that are slidably connected in a straight direction. The two needle bed guide posts 4 are fixed on the needle bed support 1 and arranged in parallel, and respectively pass through the bodies of the two connectors 2 and are interference-fitted with the corresponding bodies to achieve a fixed connection. The movable parts of the two connectors are simultaneously fixed to the needle bed cradle, thereby achieving a sliding connection between the needle bed support 1 and the needle bed cradle 3 in a straight direction through the connector 2. The connector 2 has springs 5 ​​fitted on the corresponding needle bed guide post 4 at both ends. The two ends of the springs 5 ​​abut against the ends of the needle bed guide post 4 and the body of the connector 2, respectively, so that the two ends of the body of the connector 2 are always subject to axial constraint force, thereby limiting the axial movement of the body and preventing circumferential displacement of the body after long-term use, which would interfere with the normal movement of the cradle. At the same time, it can also play a certain role in shock absorption during the relative reciprocating movement of the cradle and the bracket, thus improving the stability of the warp knitting machine.

[0024] Specifically, connector 2 is a linear bearing, which has a simple structure, is easy to install, is suitable for high-speed reciprocating motion, and has a longer service life. The front side of the needle bed cradle 3 is provided with a pair of integrally formed mounting sleeves 3-1. The needle bed bracket 1 is located above the needle bed cradle 3 and has mounting holes 1-1 corresponding to the mounting sleeves 3-1. The bottoms of the two needle bed guide pillars 4 extend to the lower end of the mounting sleeves 3-1, and their tops are inserted into the mounting holes 1-1, and are fixed by tightening with radially arranged pins. Connector 2 is located inside the mounting sleeve 3-1, and the moving part is fixed to the mounting sleeve through an interference fit. The outer circumference of the mounting sleeve 3-1 is provided with an oil nozzle communicating with connector 2, facilitating the addition of lubricating grease to the internal connector 2 and further improving its service life. Considering that excessive lubricating grease may drip, an oil collection box with a gap is provided at the bottom of the mounting sleeve 3-1, fitted onto the lower end of the needle bed guide pillar 4, to prevent grease from dripping onto the fabric below and causing contamination.

[0025] The upper and lower ends of the needle bed guide post 4 are respectively coaxially fixed with shock-absorbing washers 6. The end of the spring 5 away from the connector 2 abuts against the shock-absorbing washer 6, which eliminates the direct impact that may occur between the cradle and the bracket in relative reciprocating motion. By using the shock-absorbing washer 6 and the spring 5 together, the noise is reduced and the service life of the entire component is greatly improved.

[0026] This invention provides springs 5 ​​fitted onto needle bed guide posts 4 at both ends of the connector used to connect the needle bed support 1 and the needle bed cradle 2. The two springs 5 ​​are constrained by shock-absorbing washers 6 at both ends and kept in a pre-compressed state, continuously applying an axial force toward the center of the needle bed guide post 4 to both ends of the connector 2 body. This limits the axial movement of the body and prevents circumferential displacement of the body after long-term use, which would interfere with the normal movement of the cradle. At the same time, it can also play a certain role in shock absorption during the relative reciprocating motion of the cradle and the support, thus improving the stability of the warp knitting machine.

[0027] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
