Description

Technical Field

[0001] This utility model relates to the technical field of fabric winding devices, specifically a winding device for a warp knitting machine based on lateral pressure. Background Technology

[0002] In the warp knitting production of greige fabrics, the winding device, as a key piece of equipment connecting weaving and post-processing, directly determines the winding quality and subsequent processing efficiency of the greige fabric, occupying an indispensable position in the entire textile industry chain. The greige fabric formed by warp knitting machines through a multi-guide bar loop-forming process not only possesses significant elasticity, meeting the tensile performance requirements of various garments and industrial products, but also has wide width characteristics, adapting to the requirements of large-scale production. This necessitates that the winding process simultaneously meet the dual requirements of constant tension control and uniform pressure application, which is fundamentally different from the winding requirements of weft knitting machines, which focus on elasticity adjustment, thus posing a higher challenge to the technical level of the winding device.

[0003] Chinese patent CN221939671U discloses an auxiliary winding mechanism for a warp knitting machine, including a drive mechanism, a support, a drive wheel, a driven wheel, and an auxiliary winding belt. The drive wheel and driven wheel are mounted on the support, and the auxiliary winding belt is sleeved on the drive wheel and driven wheel. The outer surface of the auxiliary winding belt has raised patterns. A drive shaft is located in the middle of the drive wheel, and the drive shaft is connected to the output end of the drive mechanism. The driven wheel has a pin, which is connected to the support through a spring adjustment mechanism. This patent uses the driven wheel to drive the winding belt to apply a lateral pulling force to the fabric surface, converting friction into lateral tension. This does not change the winding pressure during winding, resulting in a very smooth surface of the final finished fabric bundle.

[0004] Existing devices attempt to apply lateral tension to the fabric surface by driving a winding belt with a driven wheel, converting friction into lateral tension to assist winding. This method does not change the winding pressure during winding. However, it is important to note that this structure is fixed to the winding device and its position cannot be moved. Because fabric widths vary in actual production—different batches and even the same batch of raw fabric may have different widths—this structure cannot be flexibly adjusted according to the actual width requirements of the fabric. When dealing with narrower fabrics, the tension application point may be outside the fabric's range, rendering it ineffective; when handling wider fabrics, insufficient tension coverage may cause problems such as curling and uneven edges, severely affecting winding quality and the device's versatility. Utility Model Content

[0005] The purpose of this invention is to provide a warp knitting machine winding device for knitted fabric based on lateral pressure. By setting up a telescopic drive component and a moving module, the pressure belt can be moved back and forth along the width of the fabric, thereby meeting the requirements of fabrics of different widths.

[0006] To address the problems in existing technologies, this utility model provides a warp knitting machine winding device for knitted fabric based on lateral pressure, comprising: a base plate; a winding assembly installed on the top of the base plate for winding the fabric; and a lateral pressure assembly disposed on the top of the base plate and at the input end of the winding assembly for applying tension to both sides of the fabric to prevent wrinkles from forming during winding. Two sets of the lateral pressure assemblies are provided and distributed on both sides of the fabric. Each lateral pressure assembly also includes a main body capable of vertical movement, with rotating wheels rotatably mounted at both ends of the bottom of the main body, and a pressure belt sleeved on the rotating wheels. The pressure belt can reciprocate along a direction perpendicular to the fabric.

[0007] Preferably, the surface of the pressure band is further provided with stripes to increase friction.

[0008] Preferably, a rotary drive is fixed to one side of the outer side of the main body, and the output end of the rotary drive passes through the main body and is connected to the rotary wheel.

[0009] Preferably, the lateral pressure application assembly further includes a lifting frame disposed on the top of the main body, and the lateral pressure application assembly further includes a slide bar fixed to the top of the main body and capable of slidingly engaging with the lifting frame.

[0010] Preferably, a spring is fitted on the outer side of the main body, with the bottom of the spring connected to the top of the main body and the top of the spring connected to the bottom of the lifting frame.

[0011] Preferably, the lateral pressure application component further includes a movable module disposed on the top of the base plate, and a connecting frame is slidably disposed on the movable module. A telescopic drive component is vertically installed in the connecting frame, and the output end of the telescopic drive component is connected to the lifting frame.

[0012] Preferably, the winding assembly includes a fixed plate mounted on one side of the top of the base plate, a first rotating disk rotatably mounted on the fixed plate, and a drive device for driving the first rotating disk to rotate is fixed on the outer side of the fixed plate.

[0013] Preferably, the winding assembly further includes a movable plate disposed on the other side of the top of the base plate, a second rotating disk rotatably disposed on the inner side of the movable plate, a moving mechanism for driving the movable plate to reciprocate between the movable plate and the base plate, a winding roller being held between the first rotating disk and the second rotating disk, a positioning post being disposed at the inner center of the first rotating disk and the second rotating disk, a central hole being opened in the center of the winding roller, a plurality of protrusions being disposed on the outer side of the positioning post, and a sliding groove cooperating with the protrusions being opened on the outer edge of the central hole.

[0014] The beneficial effects of this utility model are as follows: By configuring a moving module on the outside of the main body, and utilizing the linear drive characteristics of the moving module, the main body can be driven to move back and forth along the width direction of the fabric for adjustment. This structural design breaks through the fixed installation limitations of traditional transverse pressure components. By dynamically adjusting the spatial position of the main body, the pressure mechanism can adapt to knitted fabrics of different widths, effectively solving the problem of tension application point offset or incomplete coverage caused by insufficient width adaptability of existing devices. To achieve reliable contact control between the pressure belt and the fabric surface, this application sets a telescopic drive component as the actuator. By adjusting its telescopic stroke, the pressure belt can be driven to complete the position switching in the up and down directions. When a winding operation is required, the telescopic drive component drives the pressure belt downward to contact the fabric surface; when winding is completed or the roll needs to be replaced, the pressure belt is driven upward to disengage, greatly improving the ease of operation and the flexibility of equipment operation. At the same time, a spring is installed on the slide rod to form an elastic buffer mechanism. Utilizing the preload and deformation compensation characteristics of the spring, the pressure belt can always maintain a constant pressure contact state with the fabric surface during the winding process. This design can effectively offset pressure fluctuations caused by factors such as changes in roll diameter and fabric thickness deviation, ensuring the uniformity and stability of lateral pressure application, avoiding the problems of local overpressure or insufficient pressure that are easily caused by traditional rigid pressure structures, and significantly improving the winding quality of wide-width warp-knitted fabrics.

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] Reference Figures 1-6 As shown, this utility model provides a warp knitting machine winding device for knitted fabric based on lateral pressure, including: a base plate 1; a winding assembly 2, installed on the top of the base plate 1 for winding the fabric; and a lateral pressure assembly 3, located on the top of the base plate 1 and at the input end of the winding assembly 2, for applying tension to both sides of the fabric to prevent wrinkles during winding. Two sets of the lateral pressure assembly 3 are provided and distributed on both sides of the fabric. The lateral pressure assembly 3 also includes a main body 32 capable of vertical movement, with rotating wheels 33 rotatably mounted at both ends of the bottom of the main body 32. A pressure belt 31 is fitted onto the rotating wheels 33, and the pressure belt 31 can reciprocate along a direction perpendicular to the fabric. The surface of the pressure belt 31 is also provided with stripes to increase friction.

[0024] During the operation of the warp knitting machine, the fabric first passes through the transverse pressure assembly 3. Two sets of transverse pressure assemblies 3 are located on both sides of the fabric. The pressure belt 31 moves back and forth in a direction perpendicular to the fabric, using the friction increased by its surface stripes to apply tension to both sides of the fabric, keeping the fabric flat in the width direction and avoiding wrinkles.

[0025] The winding assembly 2 includes a fixed plate 21 mounted on one side of the top of the base plate 1. A first rotating disk 24 is rotatably mounted on the fixed plate 21. A driving device 23 for driving the first rotating disk 24 to rotate is also fixed on the outer side of the fixed plate 21. The driving device 23 can be a combination of a motor, belt and pulley, or a combination of motor and gear. The winding assembly 2 also includes a movable plate 26 mounted on the other side of the top of the base plate 1. A second rotating disk 27 is rotatably mounted on the inner side of the movable plate 26. A moving mechanism 25 for driving the movable plate 26 to reciprocate is also provided between the movable plate 26 and the base plate 1. The moving mechanism 25 can be a combination of a motor and a lead screw. A winding roller 22 is held between the first rotating disk 24 and the second rotating disk 27. A positioning post 28 is provided at the center of the inner side of the first rotating disk 24 and the second rotating disk 27. A center hole 221 is opened in the center of the winding roller 22. Several protrusions are provided on the outer side of the positioning post 28, and a sliding groove that cooperates with the protrusions is opened on the outer edge of the center hole 221.

[0026] During winding, the moving plate 26 is first driven away from the fixed plate 21 by the moving mechanism 25, placing the winding roller 22 on the positioning post 28 of the first rotating disk 24, so that the protrusion of the positioning post 28 is embedded in the groove of the center hole 221 of the winding roller 22. Then, the moving mechanism 25 drives the moving plate 26 closer to the fixed plate 21, so that the positioning post 28 of the second rotating disk 27 is also inserted into the center hole 221 of the other end of the winding roller 22, thus clamping and fixing the winding roller 22. After the drive device 23 is started, it drives the first rotating disk 24 to rotate. Through the cooperation of the positioning post 28 and the winding roller 22, the winding roller 22 and the second rotating disk 27 rotate synchronously. The flat fabric, after being processed by the transverse pressure component 3, is wound around the surface of the winding roller 22, completing the winding process. After winding is completed, the moving mechanism 25 drives the moving plate 26 away, so that the winding roller 22 with the wound fabric can be removed and replaced with a new winding roller 22 for the next winding.

[0027] A rotary drive component 321 is fixed to one side of the exterior of the main body 32, and the output end of the rotary drive component 321 passes through the main body 32 and is connected to the rotating wheel 33. The lateral pressure application assembly 3 also includes a lifting frame 34 disposed on the top of the main body 32, and the lateral pressure application assembly 3 also includes a slide rod 322 fixed to the top of the main body 32 and capable of slidingly engaging with the lifting frame 34.

[0028] The rotary drive 321 drives the rotary wheel 33 to rotate, which in turn drives the pressure belt 31 to apply tension to both sides of the fabric. When it is necessary to adjust the height of the main body 32 according to the fabric thickness, the lifting frame 34 can move up and down to drive the main body 32 to move up and down. At this time, the sliding cooperation between the slide rod 322 and the lifting frame 34 provides a stable guide for the movement of the main body 32, ensuring that the main body 32 and the rotary wheel 33 and the pressure belt 31 below can be accurately adjusted to the appropriate position, further ensuring the lateral pressure effect on the fabric, so that the fabric remains flat during the winding process and reduces the generation of wrinkles.

[0029] A spring 38 is sleeved on the outer side of the main body 32. The bottom of the spring 38 is connected to the top of the main body 32, and the top of the spring 38 is connected to the bottom of the lifting frame 34. The lateral pressure assembly 3 also includes a movable module 37 disposed on the top of the base plate 1, and a connecting frame 36 is slidably disposed on the movable module 37. A telescopic drive component 35 is vertically installed in the connecting frame 36, and the output end of the telescopic drive component 35 is connected to the lifting frame 34.

[0030] When it is necessary to accommodate fabrics of different widths, the moving module 37 drives the connecting frame 36 to move horizontally, which in turn moves the telescopic drive component 35, the lifting frame 34, and the main body 32 as a whole, adjusting the spacing between the two sets of transverse pressure components 3 to ensure that the pressure band 31 can act on both sides of the fabric. When adjusting the height of the main body 32, the telescopic drive component 35 extends and retracts, causing the lifting frame 34 to move up and down. The telescopic drive component 35 can be an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder, etc. At this time, the slide rod 322 guides the main body 32 to rise and fall synchronously. The spring 38 plays a buffering role in this process, avoiding rigid collisions between components, while maintaining the stability of the pressure of the pressure band 31.

[0031] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
