Description

Technical Field

[0001] This utility model relates to the field of warp knitting machines, and in particular to a novel lubrication device for the tensioner wheel of a warp knitting machine. Background Technology

[0002] A warp knitting machine is a textile machinery used to produce warp-knitted fabrics. Its working principle involves multiple warp yarns arranged parallel along the longitudinal direction (warp direction) of the machine. Guide needles lead the warp yarns through knitting needles to form loops, thus creating a knitted fabric with a specific structure and properties. Warp knitting machines are widely used in the textile industry and can produce a variety of products, including curtains, clothing fabrics, geotextiles, and medical bandages.

[0003] Currently, existing warp knitting machines require lubrication of the tension wheel, and each lubrication requires stopping the machine, removing the tension wheel assembly, adding oil, and then reinstalling the tension wheel assembly. When the warp knitting machine is running at high speed, this part is prone to wear on the bearings and parts, thus affecting the use of the warp knitting machine. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a novel lubrication device for the tension wheel of a warp knitting machine.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a novel warp knitting machine tensioner lubrication device, comprising a warp knitting machine body, a motor, a multi-wedge pulley assembly, a multi-wedge body, a tensioner assembly, and a small multi-wedge pulley assembly. The motor is mounted on the outer wall of the warp knitting machine body. The multi-wedge pulley assembly is mounted on the outer wall of the output shaft of the motor. The small multi-wedge pulley assembly is mounted inside the warp knitting machine body. The multi-wedge body is connected to the outer walls of the multi-wedge pulley assembly and the small multi-wedge pulley assembly. The tensioner assembly is mounted on the outer wall of the warp knitting machine body and presses against the multi-wedge body. The tensioner assembly includes a tensioner body, which presses against the multi-wedge body. On the surface, a tensioning shaft is installed inside the tensioning wheel body. Two bearings are movably connected inside the tensioning wheel body, and a spacer is movably connected between the two bearings. The two bearings rotate on the outer wall of the tensioning shaft, and the spacer is fixedly connected to the outer wall of the tensioning shaft. A cavity is formed between the two bearings and the spacer. An oil cup is fixedly connected inside the left end of the tensioning shaft. A first oil inlet channel is opened inside the tensioning shaft. Lubricating oil is introduced into the inlet end of the oil cup, and the outlet end of the oil cup is connected to the first oil inlet channel. A second oil inlet channel is opened inside the tensioning shaft, and the first oil inlet channel is connected to the second oil inlet channel. A through hole is opened inside the spacer, and the second oil inlet channel is connected to the through hole.

[0006] Further: The lubricating oil enters the first oil inlet channel through the oil cup outlet and then enters the cavity area through the second oil inlet channel and through hole.

[0007] Further: The first oil inlet channel is opened laterally inside the tensioning shaft, and the second oil inlet channel is opened longitudinally inside the tensioning shaft.

[0008] Furthermore, the second oil inlet channel is vertically disposed above and to the right of the first oil inlet channel, and the through hole is disposed above the second oil inlet channel.

[0009] Furthermore: the multi-wedge pulley assembly is fixedly connected to the outer wall of the output shaft of the motor, and the small multi-wedge pulley assembly is rotatably connected to the inside of the warp knitting machine body.

[0010] Further: the multi-wedge body is engaged with the outer wall of the multi-wedge pulley assembly, and the side of the multi-wedge pulley assembly away from the multi-wedge body is engaged with the outer wall of the small multi-wedge pulley assembly.

[0011] This utility model has the following beneficial effects:

[0012] 1. Compared with existing technologies, this novel warp knitting machine tensioner lubrication device connects a multi-wedge pulley assembly and a small multi-wedge pulley assembly via a multi-wedge belt body. The tensioner assembly presses against the multi-wedge belt body. Inside the tensioner body, there is a tensioning shaft, an oil cup, two bearings, a spacer, a cavity, a through hole, a first oil inlet channel, and a second oil inlet channel. Lubricating oil is introduced into the oil cup through the left inlet end. After entering the oil cup, the lubricating oil passes through the first oil inlet channel, the second oil inlet channel, and the through hole into the cavity. With the high-speed rotation of the warp knitting machine, the lubricating oil overflows and lubricates the two bearings. This solves the problem of directly lubricating without removing the tensioner assembly and addresses the issues of poor lubrication and reliability during high-speed operation of high-speed warp knitting machines.

The motor 2 is mounted on the outer wall of the warp knitting machine body 1. The multi-wedge pulley assembly 3 is mounted on the outer wall of the output shaft of the motor 2. The small multi-wedge pulley assembly 6 is mounted inside the warp knitting machine body 1. The multi-wedge body 4 uses a 10PL multi-wedge belt and is connected to the outer walls of the multi-wedge pulley assembly 3 and the small multi-wedge pulley assembly 6. The tensioner assembly 5 is mounted on the outer wall of the warp knitting machine body 1 and presses against the multi-wedge body 4. The motor 2 drives the multi-wedge pulley assembly 3 to rotate, and the rotation of the multi-wedge pulley assembly 3 drives... The multi-wedge belt body 4 and the small multi-wedge pulley coupling 6 rotate, while the tensioning pulley coupling 5 presses against the multi-wedge belt body 4, thus tensioning the multi-wedge belt body 4. The tensioning pulley coupling 5 includes a tensioning pulley body 501, which presses against the surface of the multi-wedge belt body 4. A tensioning shaft 504 is installed inside the tensioning pulley body 501. Two bearings 502 are movably connected inside the tensioning pulley body 501, and the two bearings 502 are limited to rotate inside the tensioning pulley body 501. A spacer 503 is movably connected between the two bearings 502, and the two bearings 502 rotate on the outer wall of the tensioning shaft 504. The spacer 503 is fixedly connected to the outer wall of the tensioning shaft 504. A cavity 506 is formed between the two bearings 502 and the spacer 503. An oil cup 505 is fixedly connected to the left end of the tensioning shaft 504. A first oil inlet channel 508 is provided inside the tensioning shaft 504. Lubricating oil enters through the inlet end of the oil cup 505, which is located on the left side. The outlet end of the oil cup 505 is connected to the first oil inlet channel 508, and the outlet end of the oil cup 505 is located on the right side. A second oil inlet channel 509 is provided inside the tensioning shaft 504, connecting the first oil inlet channel 508 to the second oil inlet channel 509. A through hole 507 is provided inside the spacer 503, connecting the second oil inlet channel 509 to the through hole 507. Lubricating oil enters the first oil inlet channel 508 through the outlet end of the oil cup 505 and then passes through the second oil inlet channel 509 and the through hole 507 into the cavity 506 area. The tensioning wheel body 501 and the tensioning shaft... During the rotation of 504, the lubricating oil entering the first oil inlet channel 508, the second oil inlet channel 509, and the through hole 507 is transported to the cavity 506 area. The overflowing lubricating oil lubricates the two bearings 502. The first oil inlet channel 508 is opened laterally inside the tensioning shaft 504, and the second oil inlet channel 509 is opened longitudinally inside the tensioning shaft 504. The second oil inlet channel 509 is vertically positioned above and to the right of the first oil inlet channel 508. The through hole 507 is located above the second oil inlet channel 509.

[0020] Working principle: When the warp knitting machine is running, the tensioning wheel body 501 presses the multi-wedge body 4. The motor 2 drives the multi-wedge pulley coupling 3 to rotate. The rotation of the multi-wedge pulley coupling 3 drives the multi-wedge body 4 to rotate, which in turn causes the small multi-wedge pulley coupling 6 to rotate, thus rotating the main shaft to complete the warp knitting machine's loop forming operation. The rotation of the multi-wedge body 4 also causes the tensioning wheel body 501 to rotate. Lubricating oil is introduced into the left inlet end of the oil cup 505. The lubricating oil enters the first oil inlet channel 508 through the right outlet end of the oil cup 505 and passes through the first oil inlet channel 508. 08 enters the interior of the second oil inlet channel 509, then enters the interior of the through hole 507 through the second oil inlet channel 509, and then enters the cavity 506 area. The rotation of the tension wheel body 501 drives the tension shaft 504 to rotate, thereby filling the cavity 506 area with lubricating oil. The lubricating oil overflows in the cavity 506 area to lubricate the two bearings 502. This solves the problem of lubricating the bearings 502 directly by adding lubricating oil into the interior of the tension wheel assembly 5 without removing it, and solves the problem of poor lubrication and reliability of high-speed warp knitting machines during high-speed operation.
