Description

Technical Field

[0001] This utility model relates to the field of oil change in looms, and more particularly to a water-jet loom that facilitates oil change. Background Technology

[0002] As a key piece of equipment in the textile industry, the efficient and stable operation of water jet looms is crucial to production efficiency. However, existing water jet looms face significant technical bottlenecks in oil change procedures, specifically in the following aspects:

[0003] Internal gear transmissions wear down over time, requiring the use of machine oil. This oil needs changing after prolonged machine operation. The current oil draining process relies on manual unscrewing of the drain plug, which, due to oil pressure and viscosity, easily splashes and pollutes the working environment. Furthermore, the drain plug on older equipment is often difficult to remove due to corrosion, requiring tools to forcibly tighten it, posing a risk of damaging the oil hole threads and further increasing maintenance costs. Therefore, we propose a water-jet loom design for convenient oil changing. Utility Model Content

[0004] To solve the technical problem of manually tightening bolts to drain oil in traditional methods, this utility model provides a water-jet loom that facilitates oil changes.

[0005] This utility model is achieved using the following technical solution: a water-jet loom for easy oil replacement, comprising a loom, an oil replacement mechanism, a mounting base fixedly connected to the inner wall of the loom, a fixed base mounted above the mounting base, an oil outlet base fixedly mounted on the outer side of the mounting base, a plugging oil outlet head movably connected inside the oil outlet base, an outlet groove opened on the surface of the loom, an operation groove opened on the side of the loom, and a cover plate installed on the surface of the loom.

[0006] The oil change mechanism includes a handle, a receiving handle is fixedly connected to the bottom of the handle, one end of a connecting plate is movably engaged with the inner side of the receiving handle, a deflection shaft is hinged at the connection between the receiving handle and the connecting plate, and a support shaft passes through the bottom of the receiving handle and is movably hinged to a fixed seat.

[0007] The end of the connecting plate away from the deflection axis rod is integrally fixed with a snap-fit ​​bracket. The snap-fit ​​bracket is U-shaped. One end of the push rod is snapped into the inner side of the snap-fit ​​bracket. The connection between the push rod and the snap-fit ​​bracket is hinged with a connecting axis. A movable frame is fixedly connected to the lower top of the push rod.

[0008] The operator grips the handle and applies external force. Because the bottom of the handle is fixedly connected to the receiving handle, the movement of the handle will cause the receiving handle to move. One end of the receiving handle is movably engaged with the connecting plate, and a deflection shaft is hinged at the connection point, allowing relative rotation between the receiving handle and the connecting plate. Simultaneously, the bottom of the receiving handle movably passes through a support shaft, which is movably hinged to a fixed seat mounted above the mounting base. These connecting structures ensure the stability and flexibility of the receiving handle's movement. When the receiving handle moves under the action of the handle, it rotates around the support shaft.

[0009] The rotation of the receiving handle drives the connecting plate to move via the deflection shaft. A U-shaped locking bracket is fixed to the end of the connecting plate furthest from the deflection shaft. This bracket is hinged to the push rod via the connecting shaft, allowing the movement of the connecting plate to be transmitted to the push rod. When the connecting plate moves, it pushes the push rod to move via the locking bracket and the connecting shaft. A movable frame is fixedly connected below the top of the push rod, so the movement of the push rod causes the movable frame to move synchronously.

[0010] A connecting platform is fixedly connected to the top of the oil outlet base, and the connecting platform is fixedly supported below the fixed base. The bottom end of the movable frame is fixedly connected to the plugged oil outlet. One end of the oil pump pipe is fixedly connected to the outside of the oil outlet connector, and the other end of the oil pump pipe is connected to the oil pump. An outlet groove is opened on the surface of the weaving machine.

[0011] As a further optimization of this utility model, the handle on the oil changing mechanism extends through the area of ​​the outlet groove to the outside of the housing of the weaving machine, making it convenient for the operator to grip it through the operating groove opened on the side wall of the equipment.

[0012] As a further optimization of this utility model, the bottom end of the movable frame is fixedly connected to the plugged oil outlet head, the oil outlet connector is fixedly sleeved on the outside of the oil outlet head base, and a movable groove is opened on the surface of the oil outlet connector. The oil outlet connector is a rigid connector tube, and the movable frame is inserted into the movable groove. The movable groove is opened along the axial direction of the oil outlet connector.

[0013] As a further optimization of this utility model, when the moving frame moves under the drive of the push rod, due to the guiding effect of the moving groove, the moving frame will drive the plugged oil outlet head to move along the axial direction of the oil outlet joint, thereby pressing the plugged oil outlet head into the oil outlet head base, thereby opening the oil outlet channel, and the plugged oil outlet head will then discharge oil.

[0014] As a further optimization of this utility model, when the oil outlet is blocked, the machine oil in the loom is discharged from the loom through the oil outlet base, oil outlet connector and oil pump pipeline under its own gravity or the suction of the oil pump, so as to replace the machine oil.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, through the design of an oil changing mechanism, allows operators to simply hold the handle and apply external force to drive a series of components to move in tandem, easily opening or closing the oil outlet channel without disassembling complex parts, greatly simplifying the oil changing process and significantly improving oil changing efficiency.

[0017] 2. The oil change process of this utility model is carried out in a relatively closed structure. The oil outlet and oil outlet connector are tightly fitted together, and there is an oil pump pipeline connected to the oil pump, which can effectively prevent waste oil from splashing.

[0018] 3. The oil changing mechanism of this utility model adopts a mechanical linkage design, which eliminates the need for direct contact with the drain plug, thus avoiding disassembly difficulties caused by bolt corrosion and the risk of damage to the oil hole threads.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Example 1: Please refer to Figures 1-5This embodiment proposes a water-jet loom with convenient oil replacement, including a loom device 1, an oil replacement mechanism 2 on the loom device 1, an installation base 3 fixedly connected to the inner wall of the loom device 1, a fixed seat 26 installed above the installation base 3, an oil outlet base 4 fixedly installed on the outer side of the installation base 3, a plugging oil outlet 5 movably connected inside the oil outlet base 4, an outlet groove 10 opened on the surface of the loom device 1, an operation groove 11 opened on the side of the loom device 1, and a cover plate 12 installed on the surface of the loom device 1.

[0028] The oil changing mechanism 2 includes a handle 21, a receiving handle 22 is fixedly connected to the bottom end of the handle 21, one end of a connecting plate 23 is movably engaged on the inner side of the receiving handle 22, a deflection shaft 24 is hinged at the connection between the receiving handle 22 and the connecting plate 23, and a support shaft 25 is movably passed through the bottom end of the receiving handle 22, and the support shaft 25 is movably hinged on the fixed seat 26.

[0029] A snap-fit ​​bracket 27 is integrally fixed to one end of the connecting plate 23 away from the deflection axis rod 24. The snap-fit ​​bracket 27 is U-shaped and is hinged to the push rod 29 via the connecting axis 28. A movable frame 210 is fixedly connected to the lower top of the push rod 29. The handle 21 on the oil changing mechanism 2 extends through the area of ​​the outlet groove 10 to the outside of the housing of the weaving machine 1. When it is necessary to change the oil of the water-jet loom, the cover plate 12 is opened first. The operator first comes into contact with the handle 21 located on the outside of the housing of the weaving machine 1. The handle 21 extends through the outlet groove 10 opened on the surface of the weaving machine 1, making it convenient for the operator to grasp it through the operating groove 11 opened on the side wall of the equipment. At this time, the oil outlet 5 is in the state of blocking the oil outlet base 4, preventing the oil from flowing out.

[0030] The specific technical solution involves the operator gripping handle 21 and applying external force. Since the bottom end of handle 21 is fixedly connected to receiving handle 22, the movement of handle 21 will cause receiving handle 22 to move. One end of connecting plate 23 is movably engaged on the inner side of receiving handle 22, and a deflection shaft 24 is hinged at the connection point, allowing relative rotation between receiving handle 22 and connecting plate 23. Simultaneously, the bottom end of receiving handle 22 movably passes through support shaft 25, which is movably hinged to fixed seat 26. Fixed seat 26 is mounted above mounting base 3. These connection structures ensure the stability and flexibility of the movement of receiving handle 22. When receiving handle 22 moves under the influence of handle 21, it rotates around support shaft 25.

[0031] More specifically, the rotation of the receiver 22 drives the connecting plate 23 to move via the deflection shaft 24. A U-shaped locking bracket 27 is fixed to the end of the connecting plate 23 furthest from the deflection shaft 24. One end of the push rod 29 is locked to the inner side of the locking bracket 27, and a connecting shaft 28 is hinged at the connection point. This connection method allows the movement of the connecting plate 23 to be transmitted to the push rod 29. When the connecting plate 23 moves, it pushes the push rod 29 to move via the locking bracket 27 and the connecting shaft 28. A movable frame 210 is fixedly connected to the lower part of the top of the push rod 29, so the movement of the push rod 29 will drive the movable frame 210 to move synchronously.

[0032] A connecting platform 41 is fixedly connected to the top of the oil outlet base 4. The connecting platform 41 is fixedly supported under the fixed base 26. The bottom end of the movable frame 210 is fixedly connected to the blocked oil outlet 5.

[0033] In a further technical solution, the bottom end of the movable frame 210 is fixedly connected to the plugged oil outlet head 5, and the oil outlet connector 6 is fixed to the outside of the oil outlet base 4. The oil outlet connector 6 is sleeved on the plugged oil outlet head 5, and a movable groove 7 is opened on the surface of the oil outlet connector 6. The oil outlet connector 6 is a rigid connector tube, and the movable frame 210 is inserted into the movable groove 7. The movable groove 7 is opened along the axial direction of the oil outlet connector 6. When the movable frame 210 moves under the drive of the push rod 29, due to the guiding effect of the movable groove 7, the movable frame 210 will drive the plugged oil outlet head 5 to move along the axial direction of the oil outlet connector 6, thereby pressing the plugged oil outlet head 5 into the oil outlet base 4, thereby opening the oil outlet channel and allowing the plugged oil outlet head 5 to dispense oil.

[0034] One end of the oil pump pipe 8 is connected to the outer thread of the oil outlet connector 6, and the other end of the oil pump pipe 8 is connected to the oil pump 9. When the oil outlet 5 is blocked, the machine oil in the loom is discharged from the loom through the oil outlet base 4, the oil outlet connector 6 and the oil pump pipe 8 under its own gravity or the suction of the oil pump 9, so as to change the machine oil.

[0035] The working principle of this patent is as follows:

[0036] Operational preparation phase:

[0037] When the oil in the water-jet loom needs to be changed, first open the cover 12. The operator will first encounter the handle 21 located on the outside of the loom housing 1. The handle 21 extends through the outlet groove 10 on the surface of the loom 1, allowing the operator to grip it via the operating groove 11 on the side wall of the equipment. At this time, the oil outlet 5 is in the state of blocking the oil outlet base 4, preventing the oil from flowing out.

[0038] Start the oil change mechanism:

[0039] The operator grips handle 21 and applies external force. Since the bottom end of handle 21 is fixedly connected to receiving handle 22, the movement of handle 21 will drive the receiving handle 22 to move. One end of connecting plate 23 is movably engaged on the inner side of receiving handle 22, and a deflection shaft 24 is hinged at the connection point, allowing relative rotation between receiving handle 22 and connecting plate 23. Simultaneously, the bottom end of receiving handle 22 movably passes through support shaft 25, which is movably hinged to fixed seat 26. Fixed seat 26 is mounted above mounting base 3. These connection structures ensure the stability and flexibility of the movement of receiving handle 22. When receiving handle 22 moves under the action of handle 21, it rotates around support shaft 25.

[0040] The rotation of the receiving handle 22 drives the connecting plate 23 to move via the deflection shaft 24. A U-shaped locking bracket 27 is fixed to the end of the connecting plate 23 away from the deflection shaft 24. One end of the push rod 29 is locked to the inside of the locking bracket 27, and a connecting shaft 28 is hinged at the connection point. This connection method allows the movement of the connecting plate 23 to be transmitted to the push rod 29. When the connecting plate 23 moves, it pushes the push rod 29 to move through the locking bracket 27 and the connecting shaft 28. A movable frame 210 is fixedly connected to the lower part of the top of the push rod 29, so the movement of the push rod 29 will drive the movable frame 210 to move synchronously.

[0041] Open the oil outlet channel:

[0042] The bottom end of the movable frame 210 is fixedly connected to the plugged oil outlet head 5. The oil outlet connector 6 is fixedly sleeved on the outside of the plugged oil outlet head 5, and a movable groove 7 is opened on the surface of the oil outlet connector 6. The movable frame 210 is inserted into the movable groove 7, which is opened along the axial direction of the oil outlet connector 6. When the movable frame 210 moves under the drive of the push rod 29, due to the guiding effect of the movable groove 7, the movable frame 210 will drive the plugged oil outlet head 5 to move along the axial direction of the oil outlet connector 6, thereby pressing the plugged oil outlet head 5 into the oil outlet head base 4, thereby opening the oil outlet channel and allowing the plugged oil outlet head 5 to dispense oil.

[0043] Oil drain:

[0044] One end of the oil pump pipe 8 is fixedly connected to the outside of the oil outlet base 4, and the other end of the oil pump pipe 8 is connected to the oil pump 9. When the oil outlet 5 is blocked, the machine oil in the loom is discharged from the loom through the oil outlet base 4, the oil outlet connector 6 and the oil pump pipe 8 under its own gravity or the suction of the oil pump 9, so as to change the machine oil.

[0045] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
