Description

Technical Field

[0001] This utility model relates to the field of water jet loom technology, and specifically to a hinge structure applied to a water jet loom. Background Technology

[0002] Existing flat-weave plastic water jet looms include a shedding mechanism, a water jet weft insertion mechanism, a beat-up mechanism, a warp feeding mechanism, a take-up mechanism, and other auxiliary mechanisms. These auxiliary mechanisms may include a weft yarn supply section, a length measuring device, a weft storage device, a weft yarn cutter device, a selvage device, and a warp breakage automatic stop device. Its main working principle is roughly as follows: the shedding mechanism drives the heald frame to move up and down, using plastic yarns as warp to form the shed. The weft insertion mechanism uses a water jet to bring the plastic yarns used as weft into the shed. Then, the beat-up mechanism drives the reed to beat the weft yarns into the weft hole to weave the plastic woven fabric.

[0003] The shedding mechanism of a water jet loom is achieved by connecting the heald frame and the heald frame through a drive mechanism. The hinge structure in the drive mechanism often requires regular maintenance, such as adding lubricating oil to the rotating shaft. However, the existing hinge structure needs to be waterproof, making the oiling process inconvenient. In addition, the drive mechanism operates in a wet environment, especially in the case of a bottom heald frame structure. Therefore, the drive mechanism must be waterproof while being easy to lubricate, to prevent water from entering the hinge and affecting its flexibility.

[0004] Therefore, existing technologies need further development. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a hinge structure for water jet looms, so as to solve the technical problem that the operation of adding lubricating oil to the hinge structure of water jet looms is not convenient in related technologies.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: a hinge structure for a water jet loom is provided, comprising a rotating shaft, a first connecting rod rotatably connected to the rotating shaft, and a second connecting rod fixedly connected to the rotating shaft. The rotating shaft is characterized by having an oil injection hole and an oil storage groove communicating with the oil injection hole. The oil storage groove is located on the outer circumferential surface of the rotating shaft. A first end cap and a second end cap are respectively fitted onto both ends of the rotating shaft. An oil injection nozzle communicating with the oil injection hole is installed on the first end cap and / or the second end cap. The first end cap and the second end cap are detachably connected to both ends of the rotating shaft. A closed sludge groove is formed inside the first end cap and the second end cap, and the sludge groove communicates with the oil storage groove.

[0007] Furthermore, the oil storage tank includes multiple oil storage tanks, which are distributed at intervals along the axial direction of the rotating shaft on the outer circumferential surface of the rotating shaft, and the multiple oil storage tanks are interconnected.

[0008] Furthermore, an oil injection channel is provided inside the rotating shaft, which is connected to an oil injection hole and at least one oil storage tank.

[0009] Furthermore, the first connecting rod includes a first bushing, which houses a rotating shaft. A sealing ring is provided between the outer circumferential surface of the first bushing and the first end cover and / or the second end cover to seal the interior of the first end cover and / or the second end cover.

[0010] Furthermore, a pressure plate is provided at one end of the rotating shaft near the first end cover. One side of the pressure plate abuts against the first end cover, and the other side of the pressure plate abuts against the end of the first bushing near the first end cover, so as to limit the relative position of the rotating shaft and the first bushing.

[0011] Furthermore, a first connecting boss is provided inside the first end cap, the end of the first connecting boss abuts against the pressure plate, and a mud groove is formed between the first connecting boss and the inner circumferential surface of the first end cap.

[0012] Furthermore, the pressure plate is provided with a through-hole for oil discharge, which is connected to the oil storage tank and the sludge tank respectively; wherein, there are multiple first oil discharge holes, which are distributed at intervals around the axis of the rotating shaft on the pressure plate.

[0013] Furthermore, the second end cap includes: a second connecting boss, which protrudes into the interior of the second end cap, and the end of the second connecting boss abuts against the first bushing, and a mud groove is formed between the second connecting boss and the inner wall surface of the second end cap; and a mounting groove, which is formed inside the second connecting boss, and the end of the rotating shaft is embedded in the mounting groove.

[0014] Furthermore, a second oil drain hole is provided on the second connecting boss, and the second oil drain hole is connected to the oil storage tank and the sludge tank respectively; wherein, there are multiple second oil drain holes, and the multiple second oil drain holes are distributed axially around the rotating shaft on the second connecting boss.

[0015] Furthermore, a first through hole is provided on the second connecting rod, and a first threaded hole corresponding to the first through hole is provided on the first end cap and the second end cap respectively. The end cap fastener passes through the first through hole and connects with the first threaded hole, so that the first end cap and the second end cap are fixedly connected to the second connecting rod respectively.

[0016] Beneficial effects:

[0017] 1. An oil injection nozzle is installed on the first end cover and / or the second end cover. The oil injection nozzle is connected to the oil injection hole. After lubricating oil is injected into the oil injection hole through the oil injection nozzle, the lubricating oil enters the oil storage tank and lubricates the outer circumferential surface of the rotating shaft. Then, it enters the closed sludge tank for temporary storage through the oil storage tank. By setting the first end cover and the second end cover, the inside of the rotating shaft can be shielded and sealed to prevent oil leakage from the hinge structure. At the same time, the first end cover and the second end cover can prevent water from entering the hinge, avoiding rust or damage to the rotating shaft and other structures. The first end cover and the second end cover are detachably connected to the rotating shaft, making it easy to remove the first end cover and the second end cover for cleaning the sludge tank. This solves the technical problem of inconvenient operation when adding lubricating oil to the hinge structure of the water jet loom in related technologies.

[0018] 2. As the hinge structure moves and rubs continuously, metal powder will be generated around the rotating shaft. By setting up an oil sludge tank, the metal powder can be temporarily stored in the oil sludge tank along with the lubricating oil, preventing the metal powder from accumulating around the rotating shaft and increasing the friction coefficient of the rotating shaft, thus affecting the flexibility of the rotating shaft. By setting up a first end cover and a second end cover, the hinge structure can be sealed at the same time, and the dirty lubricating oil carrying metal powder can also be temporarily stored. The dirty lubricating oil in the oil sludge tank can be cleaned periodically by removing the first end cover and the second end cover, further improving the flexibility of the hinge structure.

[0019] 3. By setting a sealing ring, firstly, the sludge tank can be sealed to prevent the lubricating oil in the sludge tank from leaking out, further ensuring the internal sealing of the hinge structure and preventing leakage. Secondly, the sealing ring will prevent external water from entering the hinge structure, thus playing a waterproof role. This allows the hinge structure to have both sealing performance and waterproof function. Attached Figure Description

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] According to an embodiment of this utility model, a hinge structure for use in a water jet loom is provided. Please refer to [link / reference]. Figures 1 to 3 The rotating shaft 3 includes a rotating shaft 3, a first connecting rod 1 rotatably connected to the rotating shaft 3, and a second connecting rod 2 fixedly connected to the rotating shaft 3. The rotating shaft 3 has an oil injection hole 31 and an oil storage groove 32 communicating with the oil injection hole 31. The oil storage groove 32 is located on the outer circumferential surface of the rotating shaft 3. A first end cover 4 and a second end cover 5 are respectively fitted on both ends of the rotating shaft 3. An oil injection nozzle 53 communicating with the oil injection hole 31 is installed on the first end cover 4 and / or the second end cover 5. The first end cover 4 and the second end cover 5 are detachably connected to both ends of the rotating shaft 3. A closed sludge groove 6 is formed inside the first end cover 4 and the second end cover 5. The sludge groove 6 is communicating with the oil storage groove 32.

[0027] Specifically, an oil injection nozzle 53 is installed on the first end cover 4 and / or the second end cover 5. The oil injection nozzle 53 is connected to the oil injection hole 31. After lubricating oil is injected into the oil injection hole 31 through the oil injection nozzle 53, the lubricating oil enters the oil storage tank 32 and lubricates the outer peripheral surface of the rotating shaft 3. Then, it enters the closed sludge tank 6 for temporary storage through the oil storage tank 32. By setting the first end cover 4 and the second end cover 5, the inside of the rotating shaft 3 can be shielded and sealed to prevent oil leakage from the hinge structure. At the same time, the first end cover 4 and the second end cover 5 can prevent water from entering the hinge, avoiding rust or damage to the rotating shaft 3 and other structures. The first end cover 4 and the second end cover 5 are detachably connected to the rotating shaft 3, making it easy to remove the first end cover 4 and the second end cover 5 to clean the sludge tank 6. This solves the technical problem of inconvenient operation when adding lubricating oil to the hinge structure of the water jet loom in related technologies.

[0028] It should be noted that as the hinge structure moves and rubs continuously, metal powder will be generated around the rotating shaft 3. By setting up the sludge tank 6, the metal powder can be temporarily stored in the sludge tank 6 along with the lubricating oil, preventing the metal powder from accumulating around the rotating shaft 3 and increasing the friction coefficient of the rotating shaft 3, thus affecting the flexibility of the rotating shaft 3. By setting up the first end cover 4 and the second end cover 5, the hinge structure can be sealed at the same time, and the dirty lubricating oil carrying metal powder can also be temporarily stored. The dirty lubricating oil in the sludge tank 6 can be cleaned periodically by disassembling the first end cover 4 and the second end cover 5, further improving the flexibility of the hinge structure.

[0029] In the hinge structure applied to the water jet loom in this embodiment, see... Figure 1 The oil storage groove 32 includes multiple grooves, which are distributed at intervals along the axial direction of the rotating shaft 3 on the outer peripheral surface of the rotating shaft 3 and are interconnected. Specifically, the multiple oil storage grooves 32 are recessed along the axial direction of the rotating shaft 3 on the outer peripheral surface of the rotating shaft 3, and as the rotating shaft 3 rotates, lubricating oil flows between the multiple oil storage grooves 32, thereby lubricating the entire outer periphery of the rotating shaft 3.

[0030] In the hinge structure applied to the water jet loom in this embodiment, see... Figure 1 The rotating shaft 3 has an oil injection channel 33, which is connected to the oil injection hole 31 and at least one oil storage groove 32. Specifically, the oil injection channel 33 can be set at a certain angle or arc so that the oil injection hole 31 is connected to any one of the oil storage grooves 32, and the lubricating oil that reaches any one of the oil storage grooves 32 can reach other oil storage grooves 32 when the rotating shaft 3 rotates.

[0031] In some embodiments, the oil injection channel 33 includes a first channel opened along the rotation axis 3 and a second channel perpendicular to the first channel. The oil storage tank 32 includes three oil storage tanks. After passing through the first channel and the second channel, the oil injection hole 31 and the centrally located oil storage tank 32 are connected, so that the lubricating oil can quickly reach all the oil storage tanks 32.

[0032] In the hinge structure applied to the water jet loom in this embodiment, see... Figure 1 The first connecting rod 1 includes a first bushing 11, which houses a rotating shaft 3. A sealing ring 7 is provided between the outer circumferential surface of the first bushing 11 and the first end cover 4 and / or the second end cover 5 to seal the interior of the first end cover 4 and / or the second end cover 5. By providing the sealing ring 7, firstly, the sludge groove 6 can be sealed to prevent the lubricating oil in the sludge groove 6 from leaking out, further ensuring the internal sealing of the hinge structure and preventing leakage. Secondly, the sealing ring 7 will prevent external water from entering the interior of the hinge structure, thus playing a waterproof role, so that the hinge structure has both sealing performance and waterproof function.

[0033] In the hinge structure of the water jet loom in this embodiment, a second bushing 8 is inserted inside the first bushing 11, and a rotating shaft 3 is inserted inside the second bushing 8. By setting the second bushing 8, the friction coefficient and friction loss of the rotating shaft 3 can be reduced, the wear resistance of the rotating shaft 3 can be improved, and the flexibility of the hinge structure can be further improved.

[0034] In the hinge structure applied to the water jet loom in this embodiment, see... Figure 1 A pressure plate 34 is provided at one end of the rotating shaft 3 near the first end cover 4. One side of the pressure plate 34 abuts against the first end cover 4, and the other side of the pressure plate 34 abuts against the end of the first bushing 11 near the first end cover 4, thereby limiting the relative position of the rotating shaft 3 and the first bushing 11. By providing the pressure plate 34, the relative position of the rotating shaft 3 and the first bushing 11 can be limited, and the flow of lubricating oil in the oil storage tank 32 can be restricted, ensuring that most of the lubricating oil remains around the rotating shaft 3 and in the oil storage tank 32.

[0035] In the hinge structure applied to the water jet loom in this embodiment, see... Figure 1 The first end cap 4 has a protruding first connecting boss 41 inside. The end of the first connecting boss 41 abuts against the pressure plate 34. An oil sludge groove 6 is formed between the first connecting boss 41 and the inner circumferential surface of the first end cap 4. By setting the first connecting boss 41, an oil sludge groove 6 can be formed inside the first end cap 4. The lubricating oil in the oil sludge groove 6 is blocked by the first connecting boss 41, the inner wall of the first end cap 4, and the sealing ring 7, thereby forming a closed oil sludge groove 6.

[0036] In the hinge structure applied to the water jet loom in this embodiment, see... Figure 1 The pressure plate 34 has a through-hole 341, which is connected to the oil storage tank 32 and the sludge tank 6. Multiple first oil drain holes 341 are distributed at intervals around the axis of the rotating shaft 3 on the pressure plate 34. By providing the first oil drain holes 341, lubricating oil containing metal powder can enter the sludge tank 6 for temporary storage.

[0037] In the hinge structure applied to the water jet loom in this embodiment, see... Figure 1The second end cover 5 includes: a second connecting boss 51, which protrudes from the interior of the second end cover 5 and abuts against the first bushing 11 at its end; a sludge groove 6 is formed between the second connecting boss 51 and the inner wall of the second end cover 5; and a mounting groove, which is formed within the second connecting boss 51 and has the end of a rotating shaft 3 embedded in it. By providing the mounting groove, the rotating shaft 3 is embedded in the mounting groove, thereby positioning the rotating shaft 3. A sludge groove 6 can be formed inside the second end cover 5. The lubricating oil in the sludge groove 6 is blocked by the second connecting boss 51, the inner wall of the second end cover 5, and the sealing ring 7, thereby forming a closed sludge groove 6.

[0038] In the hinge structure applied to the water jet loom in this embodiment, see... Figure 2 The second connecting boss 51 has a through-hole 511, which communicates with both the oil storage tank 32 and the sludge tank 6. Multiple second oil holes 511 are distributed axially around the rotating shaft 3 on the second connecting boss 51. By providing the second oil holes 511, lubricating oil containing metal powder can enter the sludge tank 6 for temporary storage.

[0039] In the hinge structure applied to the water jet loom in this embodiment, see... Figure 1 The second connecting rod 2 has a first through hole 21, and the first end cap 4 and the second end cap 5 each have a first threaded hole 52 corresponding to the first through hole 21. The end cap fastener passes through the first through hole 21 and connects to the first threaded hole 52, so that the first end cap 4 and the second end cap 5 are respectively fixedly connected to the second connecting rod 2. Through the above arrangement, the first end cap 4 and the second end cap 5 are respectively fixedly connected to the second connecting rod 2, so that the rotating shaft 3 is fixedly connected to the second connecting rod 2.

[0040] It should be noted that the first end cover 4 and the second end cover 5 are reinforced on both sides of the rotating shaft 3 with screws, thus enabling the first end cover 4 and the second end cover 5 to be detachably installed.

[0041] It should be noted that the water jet loom includes a transmission mechanism connected to the heald frame 20 for driving the heald frame 10 to move up and down reciprocally. The transmission mechanism includes the hinge structure in this embodiment. The hinge structure in this embodiment has sealing performance and waterproof function, and is also easy to add lubricating oil.
