Description

Technical Field

[0001] The present application relates to the field of valve technology, and in particular to a reverse gear valve body for a textile machine. Background Art

[0002] The forward and reverse rotation of textile machinery is achieved by using a speed change valve to drive the forward and reverse transmission of the shaft. In forward transmission, the speed change valve makes the driving shaft and the driven shaft rotate in the same direction, while in reverse transmission, the speed change valve makes the driving shaft and the driven shaft rotate in the opposite direction.

[0003] The forward and reverse rotation of textile machinery is crucial. Different operating modes have a direct impact on the quality, aesthetics, and pattern of the fabric. Forward and reverse rotation also regulates yarn tension and speed, ensuring yarn consistency and uniformity, thereby achieving high-quality textile processing.

[0004] In actual operation, the speed change valve needs to be filled with oil for lubrication to ensure smooth and rapid forward and reverse switching of the textile machine. However, due to the imperfect structure of some existing speed change valves, the oil cannot enter the valve body smoothly or a smooth oil passage cannot be formed, resulting in internal oil blockage and preventing the textile machine from switching forward and reverse smoothly. Utility Model Content

[0005] In order to solve the problem in the prior art that the oil in the speed change valve inside the textile machine cannot flow smoothly, resulting in the inability to quickly switch between forward and reverse rotations of the textile machine, which in turn affects the quality of the textile products, the present application provides a reverse valve body for a textile machine.

[0006] The reverse valve body of a textile machine provided in this application adopts the following technical solution:

[0007] A reverse valve body for a textile machine comprises a mounting plate for fixing the valve body to a speed change valve and a mounting block arranged on one side of the mounting plate, wherein the circumferential edge of the mounting plate is adapted to the shape of the speed change valve, a first mounting hole and a second mounting hole are respectively formed through the mounting plate, the mounting block is provided with an inner cavity, an oil inlet groove and an oil outlet groove are symmetrically formed on a side of the mounting block away from the mounting plate, a through hole communicating with the inner cavity is formed at the bottom of the oil inlet groove and the oil outlet groove along the axial direction, and an oil inlet port and an oil outlet port are respectively formed at the bottom of the oil inlet groove and the oil outlet groove and pass through the side of the mounting plate away from the mounting block.

[0008] By adopting the above technical solution, the oil inlet tank and the oil outlet tank are respectively connected to the oil filling pipe and the oil drain pipe on the textile machine. When the textile machine switches forward and reverse, the oil enters the speed change valve from the oil filling pipe through the oil inlet port, and then enters the oil drain pipe from the oil outlet port for discharge. When the oil flow rate is too large and exceeds the bearing range of the speed change valve, the excess oil will flow back from the oil inlet tank to the oil outlet tank through the through holes at the bottom of the oil inlet tank and the oil outlet tank and the inner cavity connected to the through holes, thereby reducing the pressure of the speed change valve and avoiding blockage or leakage of the oil inside the speed change valve. In addition, when the oil inside the speed change valve is insufficient, the oil can also be replenished by introducing the oil in the inner cavity into the oil inlet port.

[0009] Optionally, the inner cavity is circular in shape along the cross section, and the axis of the inner cavity is perpendicular to the axes of the oil inlet groove and the oil outlet groove.

[0010] By adopting the above technical solution, the oil can flow smoothly without occupying too much internal volume of the installation block. In addition, the circular cross-section of the inner cavity also facilitates rapid flushing when the oil in the inner cavity is blocked.

[0011] Optionally, first screw holes for fixing the mounting block and the connecting structure are formed through the mounting block at a side away from the fixing plate near the four corners.

[0012] By adopting the above technical solution, it is easy to fix the mounting block and the mounting plate to prevent the oil inside the valve body from splashing out due to the shaking of the equipment during the operation of the textile machine, thereby improving the safety of the equipment during use.

[0013] Optionally, a plurality of irregularly shaped material reduction holes are provided on a side of the mounting block away from the mounting plate.

[0014] By adopting the above technical solution, the material consumption during the manufacture of the valve body can be reduced, thereby improving its economic applicability.

[0015] Optionally, a plurality of connection holes for connecting with the speed change valve to ensure that the valve body does not shake are opened circumferentially on the mounting plate, and the diameters of the plurality of connection holes are equal.

[0016] By adopting the above technical solution, the mounting plate can be fixed on the speed change valve to avoid sliding caused by an unstable connection structure.

[0017] Optionally, the mounting block is provided with stepped grooves at the oil inlet groove and the oil outlet groove on a side away from the mounting plate, and the two stepped grooves are both opened in the middle position of the mounting block and are symmetrically distributed along the short side direction of the mounting block.

[0018] By adopting the above technical solution, the oil filling pipe and the oil drain pipe can form a sealed installation structure with the liquid inlet groove and the liquid outlet groove respectively to avoid leakage. In addition, the two stepped grooves are symmetrically opened on one side of the mounting block, which can also ensure that the oil filling pipe and the oil drain pipe will not occupy too much space during installation when the inner cavity has the maximum volume.

[0019] Optionally, a plurality of placement grooves are provided on a side of the mounting plate away from the mounting block.

[0020] By adopting the above technical solution, the placement groove can abut against the internal parts of the speed change valve, so as to fix the parts and improve the stability of the overall structure of the speed change valve.

[0021] Optionally, the mounting block is provided with thickened structures at the four corners where the first screw holes are provided.

[0022] By adopting the above technical solution, the connection structure of the valve body can be reinforced, and the mounting block is not easily damaged.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. This application provides through-holes at the bottom of the oil inlet and outlet grooves of the valve body, and an inner cavity connected to both through-holes within the mounting block. This allows excess oil to flow back through the inner cavity, preventing oil blockage inside the speed change valve. The inner cavity can also be used to replenish the oil inside the speed change valve, thereby improving the forward and reverse rotation smoothness of the textile machine.

[0025] 2. This application designs the structure of the valve body to make the connection structure between the valve body and the oil filling pipe, oil drain pipe and the speed change valve body more stable, which can avoid oil splashing and causing danger or machine failure.

[0032] The following is combined with Figure 1-5 This application is described in further detail.

[0033] An embodiment of the present application discloses a reverse valve body for a textile machine.

[0034] Reference Figure 1 A reverse valve body for a textile machine is fixedly mounted on the main body of the machine's speed change valve. It includes a mounting plate 1 and a mounting block 2 fixedly connected to the mounting plate 1. The edge of the mounting plate 1 is designed with a curved structure that adapts to the speed change valve, thereby achieving a more stable connection with the speed change valve. Furthermore, the mounting plate 1 is provided with a plurality of connecting holes 11 to ensure a more stable connection with the speed change valve when connected, preventing shaking and oil spillage. To facilitate manufacturing and installation, the diameters of the plurality of connecting holes 11 are designed to be equal.

[0035] Furthermore, a plurality of placement grooves 12 are provided on the side of the mounting plate 1 away from the mounting block 2 so that the mounting structure of the parts inside the speed change valve is more stable and less likely to shake.

[0036] Reference Figure 1 and Figure 2 Furthermore, a first mounting hole 13 and a second mounting hole 14 are formed through the mounting plate 1 for securing the mounting plate 1 and the mounting block 2 to the speed change valve. Specifically, the first mounting hole 13 and the second mounting hole 14 have the same shape and size, and both have a stepped hole structure to reduce the space occupied by the mounting structure.

[0037] Reference Figure 1 and Figure 3 The mounting block 2 is provided with first screw holes 26 for fixing the mounting block 2 at positions near the four corners on the side away from the mounting plate 1, and reinforcements are provided at the positions of the first screw holes 26 to prevent the mounting block 2 from breaking when subjected to a large force, thereby causing damage to the valve body.

[0038] Reference Figure 1 and Figure 3 Furthermore, a plurality of irregularly shaped material reduction holes 27 are provided on the side of the mounting block 2 away from the mounting plate 1 to reduce the material used in manufacturing the valve body and improve its economic applicability.

[0039] Reference Figure 1 and Figure 3 The middle part of the mounting block 2 is provided with an inner cavity 21 along the length direction for the oil to flow in, and the shape of the inner cavity 21 along the cross-section is circular, so that the oil can flow more smoothly and avoid the result of oil blockage inside the inner cavity 21. The mounting block 2 is provided with an oil inlet groove 22 and an oil outlet groove 23 on the side away from the mounting plate 1. The oil inlet groove 22 and the oil outlet groove 23 are respectively connected and sealed with the oil filling pipe 3 and the oil drain pipe 4 to prevent the oil from leaking out. The mounting block 2 is provided with a through hole 24 connected to the inner cavity 21 at the bottom of the oil inlet groove 22 and the oil outlet groove 23, so that excess oil can be directly discharged to the outside of the speed change valve through the inner cavity 21. At the same time, when the oil inside the speed change valve is insufficient, the oil can also be sent into the speed change valve through the inner cavity 21.

[0040] Reference Figure 3 、 Figure 4 and Figure 5 Furthermore, an oil inlet 221 and an oil outlet 231 are respectively provided at the bottom of the oil inlet groove 22 and the bottom of the oil outlet groove 23, which are connected to the side of the mounting plate 1 away from the mounting block 2, so that the oil inside the oil filling pipe 3 enters the interior of the speed change valve through the oil inlet 221 and is then discharged from the oil drain pipe 4 of the oil outlet 231.

[0041] Furthermore, in order to allow the oil to smoothly enter the inner cavity 21 so that the inner cavity 21 can store some of the oil, the through hole 24 is designed to be located at the bottom center of the oil inlet groove 22 and the oil outlet groove 23, and the oil inlet port 221 and the oil outlet port 231 are respectively opened inside the oil inlet groove 22 and the oil outlet groove 23 on the same side of the inner cavity 21 along the length direction.

[0042] Reference Figure 4 and Figure 5 The mounting block 2 is provided with a stepped groove 25 at the oil inlet groove 22 and the oil outlet groove 23 so that the oil filling pipe 3 and the oil drain pipe 4 are sealed and connected to the oil inlet groove 22 and the oil outlet groove 23 respectively to prevent the oil from flying out from the connection position.

[0043] Preferably, the two stepped grooves 25 are both opened in the middle position of the mounting block 2 and are symmetrically distributed along the short side direction so that the volume of the inner cavity 21 can reach the maximum.

[0044] The implementation principle of the reverse valve body of a textile machine in the embodiment of the present application is as follows:

[0045] The oil enters the speed shift valve through the oil inlet hole from the oil filling pipe 3 located in the oil inlet groove 22, and then is discharged from the oil outlet hole to the inside of the oil drain pipe 4 located in the oil outlet groove 23, forming an oil passage to prevent the oil from being blocked in the speed shift valve.

[0046] When the oil in the speed change valve is too much, the oil in the oil inlet groove 22 can enter the inner cavity 21 through the through hole 24, and then be discharged from the inner cavity 21 to the oil drain pipe 4, thereby preventing the oil from being blocked. When the oil in the speed change valve is low, the oil in the inner cavity 21 enters the oil inlet groove 22 through the through hole 24, providing oil replenishment for the speed change valve.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
