Description

Technical Field

[0001] This utility model relates to the field of warp knitting machine technology for sofa fabrics, specifically a warp knitting machine for sofa fabrics with adjustable rollers. Background Technology

[0002] A warp knitting machine for sofa fabrics is a type of textile machinery based on warp knitting technology. It uses one or more sets of parallel warp yarns, which interweave according to a specific pattern under the action of loop-forming components (such as latch needles and groove needles) to form a fabric. The warp yarns are drawn from the warp beam, pass through guide needles and other components, and, with the cooperation of the needle bed, knit sofa fabrics with a specific structural structure.

[0003] According to a public notice (No. CN116281306A) of a warp knitting machine for sofa fabric, the position of the take-up roller in the above application is fixed. Therefore, the distance between the two sets of rollers cannot be adjusted during use. The inability to adjust the distance makes it difficult to optimize the take-up process according to the characteristics of the fabric. Some rollers with adjustment structures are only adjusted in a single way without considering the drawbacks caused by excessively fast adjustment speed. When the roller adjustment speed is too fast, the tension of the fabric will suddenly change. For example, when the distance between the rollers is increased rapidly, the fabric will loosen instantly, which may lead to problems such as fabric accumulation and wrinkles. In order to solve this problem, we propose a warp knitting machine for sofa fabric with adjustable rollers. Utility Model Content

[0004] The purpose of this invention is to provide a warp knitting machine for sofa fabrics with adjustable rollers, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a warp knitting machine for sofa fabric with adjustable rollers, comprising a warp knitting machine frame, a connecting frame fixedly installed on the inner wall of the warp knitting machine frame, an electric roller I disposed within the connecting frame, an electric roller II penetrating the connecting frame and slidably connected to the electric roller II, a fixed frame fixedly installed on the surface of the connecting frame, and an adjustment control component disposed within the fixed frame, the control component comprising: a moving block, the moving block penetrating the connecting frame and slidably connected to the connecting frame, an electric roller II disposed on the surface of the moving block, a threaded rod penetrating the moving block and threadedly connected to the threaded rod, the threaded rod penetrating the fixed frame and rotatably connected to the fixed frame, the threaded rod penetrating a cylinder and fixedly connected to the cylinder, the surface of the cylinder hinged to a protrusion, the surface of the protrusion fixedly connected to one side of a torsion spring, and the other side of the torsion spring fixedly installed on the surface of the cylinder, thereby preventing the fabric from piling up, wrinkling, or being strongly stretched due to excessively fast adjustment speed of the moving block and the electric roller II.

[0006] Preferably, the surface of the protrusion is arc-shaped, which allows the arc-shaped protrusion to fold more easily when it is pressed.

[0007] Preferably, the control assembly further includes an adjusting component, which includes a fixing rod. The fixing rod is fixedly installed on the inner wall of the fixing frame. The fixing rod passes through the ball and is rotatably connected to the ball. When the ball is abutted, it can rotate on the surface of the fixing rod.

[0008] Preferably, the threaded rod passes through the circular plate and is fixedly connected to the circular plate, the circular plate is rotatably connected to the inner wall of the fixing frame, and a slot is provided on the surface of the circular plate to restrict the rotation of the circular plate and the threaded rod.

[0009] Preferably, a turntable is fixedly mounted on the surface of the threaded rod, and the turntable is rotatably connected to the surface of the fixed frame. When the turntable rotates on the surface of the fixed frame, the turntable can drive the threaded rod to rotate synchronously within the fixed frame.

[0010] Preferably, a support frame is fixedly installed on the surface of the fixing frame, the inner wall of the support frame is fixedly connected to one end of the spring, the other end of the spring is fixedly installed on the surface of the slide rod, the slide rod is in contact with the inner wall of the support frame, and when the slide rod is no longer subjected to an upward thrust, it can bounce up in the support frame under the support of the spring.

[0011] Preferably, a locking rod is fixedly installed on the surface of the slide rod. The locking rod passes through the fixing frame and is slidably connected to the fixing frame. When the slide rod moves, the locking rod fixed on the surface of the slide rod can move longitudinally synchronously within the fixing frame.

[0012] Compared with the prior art, this utility model provides a warp knitting machine for sofa fabrics with adjustable rollers, which has the following beneficial effects:

[0013] 1. This adjustable roller warp knitting machine for sofa fabrics, through the setting of a control component, allows the threaded rod to rotate within the fixed frame under the action of the turntable. The moving block can drive the electric roller two to move laterally to adjust the spacing. When the threaded rod rotates, the cylinder fixed on the surface of the threaded rod can move in a circular motion simultaneously. When the cylinder rotates, the protrusion hinged on the surface of the cylinder can fold on the surface of the cylinder under the support of the torsion spring when it comes into contact with the surface of the ball. This method can buffer the rotation speed of the moving block and the threaded rod, and avoid the fabric from piling up, wrinkling or being stretched strongly due to the excessive adjustment speed of the moving block and the electric roller two.

[0014] 2. This adjustable roller warp knitting machine for sofa fabrics features an adjustable mechanism. Because the threaded rod passes through and is fixedly connected to the circular plate, the circular plate can synchronously rotate within the fixed frame when the threaded rod rotates. The surface of the circular plate has a slot, so when the locking rod is located in the slot within the circular plate, the circular plate and the threaded rod cannot rotate synchronously. This method can provide secondary fixation for the position adjustment of the second electric roller, preventing changes in the distance between the second electric roller and the first electric roller due to accidental contact or collision during use, thus affecting the operation.

[0020] like Figures 1-4As shown, this utility model provides a technical solution: a warp knitting machine for sofa fabric with adjustable rollers, including a warp knitting machine frame 1, a connecting frame 2 fixedly installed on the inner wall of the warp knitting machine frame 1, an electric roller 3 disposed inside the connecting frame 2, the connecting frame 2 being penetrated by an electric roller 4 and slidably connected to the electric roller 4, a fixing frame 5 fixedly installed on the surface of the connecting frame 2, and a control component 6 for adjustment disposed inside the fixing frame 5, the control component 6 including: a moving block 61, the moving block 61 penetrating the connecting frame 2 and slidably connected to the connecting frame 2, the surface of the moving block 61 being provided with an electric roller 4, the moving block 61 being penetrated by a threaded rod 62 and threadedly connected to the threaded rod 62, the threaded rod 62 penetrating the fixing frame 5 and... The threaded rod 62 is rotatably connected to the fixed frame 5, passes through the cylinder 63 and is fixedly connected to the cylinder 63. The surface of the cylinder 63 is hinged to the protrusion 64. The surface of the protrusion 64 is fixedly connected to one side of the torsion spring 65. The other side of the torsion spring 65 is fixedly installed on the surface of the cylinder 63. During the rotation of the cylinder 63, the protrusion 64 will abut against the surface of the ball 662 and fold under the support of the torsion spring 65. At the same time, the ball 662 can roll on the surface of the fixed rod 661. This method can buffer the rotation speed of the moving block 61 and the threaded rod 62, and avoid the fabric from piling up, wrinkling or being strongly stretched due to the excessive speed adjustment of the moving block 61 and the electric roller 4.

[0021] The surface of the protrusion 64 is arc-shaped, which allows for better folding when abutted. The control assembly 6 also includes an adjusting component 66, comprising: a fixed rod 661, which is fixedly mounted on the inner wall of the mounting frame 5, passes through and is rotatably connected to a ball bearing 662, allowing the ball bearing 662 to rotate on the surface of the fixed rod 661 when abutted; a threaded rod 62, which passes through and is fixedly connected to a circular plate 663, which is rotatably connected to the inner wall of the mounting frame 5, and has a slot 664 on its surface, which restricts the rotation of both the circular plate 663 and the threaded rod 62; and a turntable 665, which is rotatably connected to the surface of the mounting frame 5, causing the threaded rod 62 to rotate synchronously within the mounting frame 5 when rotated on its surface. A support frame 666 is fixedly mounted on the surface of the fixed frame 5. The inner wall of the support frame 666 is fixedly connected to one end of a spring 668, and the other end of the spring 668 is fixedly mounted on the surface of a slide rod 667. The slide rod 667 fits against the inner wall of the support frame 666. When the slide rod 667 is no longer subjected to an upward thrust, it can spring up within the support frame 666 with the support of the spring 668. A locking rod 669 is fixedly mounted on the surface of the slide rod 667. The locking rod 669 passes through the fixed frame 5 and is slidably connected to the fixed frame 5. When the slide rod 667 moves, the locking rod 669 fixed to the surface of the slide rod 667 can move longitudinally synchronously within the fixed frame 5.

[0022] In this invention, when it is necessary to adjust the distance between the electric roller 3 and the electric roller 4 according to the thickness of the sofa fabric, the slide rod 667 is pushed upward within the support frame 666. When the slide rod 667 moves, it can compress the spring 668. At the same time, the locking rod 669 fixed on the surface of the slide rod 667 can move longitudinally within the fixed frame 5 and move out of the slot 664 opened on the surface of the circular plate 663. After moving out, the pushing force is maintained, and the turntable 665 rotates on the surface of the fixed frame 5. When the turntable 665 rotates, the threaded rod 62 fixed on the surface of the turntable 665 drives the circular plate 663 to rotate within the fixed frame 5. When the threaded rod 62 rotates, the moving block 61 can be forcefully adjusted to adjust the position of the electric roller 4. At the same time, when the threaded rod 62 rotates, the cylinder 63 fixed on the surface of the threaded rod 62 can rotate synchronously within the fixed frame 5. During the rotation of cylinder 63, protrusion 64 will abut against the surface of ball 662 and fold under the support of torsion spring 65. At the same time, ball 662 can roll on the surface of fixed rod 661. This method can buffer the rotation speed of moving block 61 and threaded rod 62, and avoid the fabric from piling up, wrinkling or being stretched too much due to excessive adjustment speed of moving block 61 and electric roller 4. After the spacing is adjusted, the force of pushing slide rod 667 is released, and slide rod 667 can spring up under the support of spring 668. The locking rod 669 fixed on the surface of slide rod 667 can be re-locked into the locking groove 664 opened on the surface of circular plate 663. This method can fix the position adjustment of electric roller 4 for a second time, and avoid the spacing between electric roller 4 and electric roller 3 from changing due to accidental contact or collision during use, thus affecting the use.

[0023] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
