Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile machinery and equipment, specifically to a pressure roller device for adjusting the tension of a synchronous belt. Background Technology
[0002] In warp knitting machines, the timing belt is a key transmission component, and its tension has a crucial impact on the stable operation and production efficiency of the equipment. If the timing belt is improperly tensioned, being too loose will cause it to slip, reducing the transmission accuracy of the warp knitting machine, lowering the quality of the fabric, and may even lead to equipment failure; while being too tight will increase wear on the timing belt, shorten its service life, and also place an additional burden on other components of the equipment.
[0003] Currently, after a warp knitting machine has been running for a long time, the timing belt will gradually loosen due to wear and other factors. At this time, it is necessary to adjust its tension in a timely and accurate manner. However, the existing tensioning device of the warp knitting machine is not flexible and precise enough. Its tensioning device is difficult to make small and precise adjustments, and cannot meet the precise requirements of the timing belt for tension under different working conditions, which can easily lead to the timing belt being too loose or too tight.

[0007] Furthermore, the fixing screw includes a screw portion and a rotating portion, the rotating portion being disposed at the bottom end of the screw portion, and the rotating portion being integrally formed with the screw portion.
[0008] Furthermore, the end of the rotating shaft is provided with an anti-loosening nut, which is threadedly connected to the end of the rotating shaft.

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0018] Reference Figures 1-3As shown, a pressure roller device for adjusting the tension of a timing belt includes a mounting plate 1, a connecting seat 2, a connecting plate 3, a pressure roller mechanism 4, and an adjusting mechanism 5. The connecting seat 2 is disposed at the bottom of the mounting plate 1. There are two connecting plates 3, which are symmetrically arranged on both sides of the connecting seat 2, and the middle part of the connecting plate 3 is rotatably connected to the connecting seat 2. The pressure roller mechanism 4 is disposed at one end of the connecting plate 3 and is used to press against the timing belt to adjust the tension of the timing belt. The adjusting mechanism 5 is disposed at the other end of the connecting plate 3 and is used to drive the connecting plate 3 to rotate so as to flexibly adjust the height position of the pressure roller mechanism 4, thereby achieving precise adjustment of the tension of the timing belt.
[0019] The adjusting mechanism 5 includes a mounting hole, a lifting hole, a fixing screw 51, a rotating hole, a rotating shaft 52, and a fixing nut 53. The mounting hole is located on the connecting plate 3, the lifting hole is located on the mounting plate 1, the fixing screw 51 passes through the lifting hole, the rotating hole is located at the bottom of the fixing screw 51, the rotating shaft 52 passes through the rotating hole, and the end of the rotating shaft 52 is located in the mounting hole. The fixing nut 53 is located on the fixing screw 51 and is positioned above the connecting plate 3. Specifically, by rotating the fixing nut 53, the fixing screw 51 can move up and down within the lifting hole, thereby driving the connecting plate 3 to rotate, achieving adjustment of the height of the pressure roller mechanism 4, and thus achieving precise adjustment of the synchronous belt tension.
[0020] The fixing screw 51 includes a screw portion 511 and a rotating portion 512. The rotating portion 512 is disposed at the bottom end of the screw portion 511 and is integrally formed with the screw portion 511. The rotating hole is located on the rotating portion 512.
[0021] The rotating shaft 52 has an anti-loosening nut 6 at its end, which is threaded to the end of the rotating shaft 52 and located on the outside of the connecting plate 3. The anti-loosening nut 6 prevents the rotating shaft 52 from falling out of the mounting hole, ensuring the stability of the device.
[0022] The pressure roller mechanism 4 includes a pressure roller shaft 41 and a pressure roller 42. The pressure roller shaft 41 is mounted on the connecting plate 3, and the pressure roller 42 is rotatably mounted on the pressure roller shaft 41. The pressure roller 42 presses against the timing belt, and the tension of the timing belt is adjusted by adjusting the height of the pressure roller 42.
[0023] A bearing 7 is provided between the pressure roller shaft 41 and the pressure roller 42. The bearing 7 reduces the frictional resistance between the pressure roller 42 and the pressure roller shaft 41, making the pressure roller 42 rotate more smoothly and improving the adjustment efficiency.
[0024] The connecting plate 3 has a triangular structure.
[0025] The connecting seat 2 and the mounting plate 1 are fastened together by bolts.
[0026] Specifically, when it is necessary to adjust the tension of the timing belt, the fixing nut 53 is rotated, and the fixing nut 53 moves on the fixing screw 51, causing the fixing screw 51 to move up and down within the lifting hole. The movement of the fixing screw 51 drives the connecting plate 3 to rotate around the connecting seat 2 via the rotating shaft 52, thereby causing the pressure roller 42 of the pressure roller mechanism 4 to move up and down, thus adjusting the tension of the timing belt. By precisely controlling the rotation angle of the fixing nut 53, minute adjustments to the tension of the timing belt can be achieved to meet the usage requirements under different working conditions.
[0027] The above are only some specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
