Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically to a pressing device for a water-jet loom used in textile fabric processing. Background Technology

[0002] A water jet loom is a modern weaving machine that uses high-pressure water jets to guide the weft yarn into the fabric weave. Water jet looms offer advantages such as high speed, high efficiency, and strong adaptability, and are widely used in the textile industry, especially for weaving hydrophobic fibers (such as polyester and nylon).

[0003] For example, the water-jet loom with Chinese patent publication number CN221398254U relates to the field of fabric production technology. This water-jet loom includes a water collection tank, a cleaning assembly, and a transmission assembly. The water collection tank houses the loom body, and the cleaning assembly is located on the water collection tank. The cleaning assembly is used to clean lint. The transmission assembly is located on the cleaning assembly and includes a rotating rod, a transmission wheel, a conveyor belt, an electric push rod, a toothed plate, and gears. The electric push rod drives the toothed plate to move, the toothed plate drives the gears to rotate, the gears drive the rotating rod to rotate, the rotating rod drives the conveyor belt to rotate, and the conveyor belt drives the cleaning assembly to perform cleaning.

[0004] The water jet loom described in the aforementioned patent can only perform internal cleaning during use. However, the existing water jet loom's internal pressing device lacks a lubricating component for the bobbin shaft, causing the bobbin and bearing to become dry after long-term use. Therefore, an improved device is needed to address this problem. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressing device for a water-jet loom for textile fabric processing, comprising a support device, and an alignment device fixedly installed at equal intervals on the side end of the support device. The alignment device includes a nozzle, a support cavity, a bobbin, a shaft, a sealing plate, a bearing, a bearing seat, an accumulation cavity, a circulation pump, and an oil pipe. The sealing plate is symmetrically fixedly installed inside the front end of the support cavity. The bearing seat is fixedly installed inside the front end of the support cavity and is located behind the sealing plate. The bearing is installed at the top of the bearing seat. The circulation pump is fixedly installed at the rear end of the support cavity. The oil pipe is fixedly installed at the top of the circulation pump. The nozzle is fixedly installed at the bottom front end of the oil pipe. The shaft is installed inside the bearing. The bobbin is fixedly installed at the front end of the shaft. The accumulation cavity is fixedly installed behind the bottom end of the support cavity.

[0007] Preferably, the support device includes a special-shaped connecting rod, a hydraulic cylinder, and a support base. The hydraulic cylinder is symmetrically and fixedly installed on the top of the support base, and the special-shaped connecting rod is fixedly installed on the top of the hydraulic cylinder.

[0008] Preferably, the top end of the support cavity is connected to the front end of the irregular connecting rod.

[0009] Preferably, the interior of the accumulation cavity is hollow, and the support cavity, accumulation cavity, circulation pump and oil pipe are interconnected.

[0010] Preferably, the support cavity has a through hole at its inner bottom end away from the sealing plate.

[0011] Preferably, the nozzle is vertically aligned with the bearing.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] When in use, this device allows the lubricating oil inside the support cavity to flow back into the collection cavity for collection through the interconnection between the accumulation cavity and the support cavity. At the same time, when the circulation pump is turned on, the lubricating oil can be discharged into the nozzle through the oil pipe, so that the nozzle can spray the lubricating oil onto the area where the bearing and shaft meet, so that the shaft is sufficiently lubricated. Furthermore, the support cavity is sealed by the sealing plate to prevent the lubricating oil from flowing out of the support cavity. When the circulation pump is started, the lubricating oil circulates within the support cavity, so as to perform circulating lubrication of the bearing. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present 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 the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model provides an embodiment of a water-jet loom pressing device for textile fabric processing, comprising a support device 2, with alignment devices 1 fixedly installed at equal intervals on the side end of the support device 2. The alignment device 1 includes a nozzle 3, a support cavity 4, a bobbin 5, a shaft 6, a sealing plate 7, a bearing 8, a bearing seat 9, an accumulation cavity 10, a circulation pump 11, and an oil pipe 12. The sealing plate 7 is symmetrically fixedly installed inside the front end of the support cavity 4, the bearing seat 9 is fixedly installed inside the front end of the support cavity 4 and is located behind the sealing plate 7, the bearing 8 is installed at the top of the bearing seat 9, the circulation pump 11 is fixedly installed at the rear end of the support cavity 4, the oil pipe 12 is fixedly installed at the top of the circulation pump 11, the nozzle 3 is fixedly installed at the bottom front end of the oil pipe 12, the shaft 6 is installed inside the bearing 8, the bobbin 5 is fixedly installed at the front end of the shaft 6, and the accumulation cavity 10 is fixedly installed behind the bottom end of the support cavity 4.

[0020] The support device 2 includes a special-shaped connecting rod 13, a hydraulic cylinder 14, and a support base 15. The hydraulic cylinder 14 is symmetrically fixedly installed on the top of the support base 15, and the special-shaped connecting rod 13 is fixedly installed on the top of the hydraulic cylinder 14. When the hydraulic cylinder 14 is opened, the special-shaped connecting rod 13 can be driven to move up and down, so that the pressure on the pressing thread can be adjusted.

[0021] The top of the support cavity 4 is connected to the front end of the irregular connecting rod 13. When the irregular connecting rod 13 is displaced, it can drive the alignment device 1 at the top center of the support base 15 to be displaced.

[0022] The interior of the storage cavity 10 is hollow, and the support cavity 4, the storage cavity 10, the circulation pump 11 and the oil pipe 12 are interconnected, which facilitates the flow of lubricating oil inside the support cavity 4, the storage cavity 10, the circulation pump 11 and the oil pipe 12.

[0023] The support cavity 4 has a through hole at its bottom interior, away from the sealing plate 7, to facilitate the flow of lubricating oil into the storage cavity 10.

[0024] The nozzle 3 is vertically aligned with the bearing 8 to facilitate spraying lubricating oil onto the surface of the bearing 8.

[0025] Working Principle: In use, the support base 15 can be installed on an external water jet loom. An alignment device 1 is installed at each of the front ends of the support base 15, and another alignment device 1 is installed on the irregular connecting rod 13 at the top of the support base 15. The yarn is passed through the two yarn wheels 5 at the front end of the support base 15. Then, the hydraulic cylinder 14 is activated, causing the alignment device 1 at the center of the top of the support base 15 to move downwards. This causes the yarn wheel 5 at the center of the top of the support base 15 to press and tension the yarn, completing the yarn pressing operation. When the yarn wheel 5 rotates, the circulation pump 11 can be started. Lubricating oil is stored in the accumulation chamber 10, and an oil pipe 12 is installed between the circulation pump 11 and the accumulation chamber 10. When the circulation pump 11 starts, the lubricating oil inside the accumulation chamber 10 is discharged into the nozzle 3 through the oil pipe 12. The nozzle 3 is vertically aligned with the bearing 8, allowing the lubricating oil to... The lubricating oil is sprayed onto the surfaces of bearing 8 and shaft 6, completing the lubrication of bearing 8 and shaft 6. At the same time, the lubricating oil dripping from bearing 8 and shaft 6 is connected to the top of accumulation cavity 10 through the through hole at the bottom of support cavity 4, so that the lubricating oil can flow back into accumulation cavity 10 through the through hole, which facilitates the continuous delivery of lubricating oil to oil pipe 12 by circulation pump 11. Meanwhile, when the lubricating oil flows over the surfaces of bearing 8 and shaft 6, it can carry away the heat from the surfaces of bearing 8 and shaft 6, preventing the bearing 8 from overheating during long-term operation. When this device is in use, two sealing plates 7 are installed at the front end of the inside of support cavity 4 to prevent lubricating oil from leaking out. At the same time, by opening hydraulic cylinder 14, the irregular connecting rod 13 is moved up and down, so that the thread wheel 5 in the center alignment device 1 at the top of support base 15 can control the pressure of pressing the thread, so that the thread can always be kept taut.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
