Detailed Implementation

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figures 1-4This utility model provides an oil level alarm device for an EFK texturing machine, including an oil tank body 1. A sealing cover plate 21 is fixedly connected to the top of the oil tank body 1. An oil level alarm body 22 is installed on the top of the sealing cover plate 21. A sealing tube 23 is installed on the top of the oil level alarm body 22, extending downward into the interior of the oil tank body 1. Mounting plates 24 are installed on both sides of the oil level alarm body 22. The mounting plates 24 and the sealing cover plate 21 have slots 25 inside. A fixing rod is engaged inside the slots 25. A guide block 28 is engaged inside the fixing rod. A guide rod 29 is fixedly connected to the top of the guide block 28, with part of the guide rod 29 extending out of the fixing rod. A guide plate 31 is fixedly connected to the top of the guide rod 29. During operation, when it is necessary to install the oil level alarm body 22, the oil level alarm body 22 is installed on the top of the sealing cover plate 21, and then the mounting plates are moved. 24 is attached to the top of the sealing cover plate 21. Then, by inserting the fixing rod into the inside of the slot 25, the guide plate 31 is pushed to drive the guide rod 29 and the guide block 28 to be inserted into the inside of the fixing rod to squeeze the end of the locking block 27. This causes the locking block 27 to be squeezed and slide to both sides to be inserted into the inside of the guide hole for locking and fixing, so as to quickly install the sealing tube 23. After installation, the sealing tube 23 can be directly inserted into the oil tank body 1. The sealing tube 23 is equipped with a float, a capacitive sensor, an LED light, a control chip, etc., so that the sealing tube 23 can detect the oil in the oil tank body 1. When the oil level is lower than the limit value during production, the sealing tube 23 acts as a detection tool to feed back the real-time oil level to the oil level alarm body 22 for alarm processing. The locking insertion method makes it more convenient for users to install the sealing tube 23.

[0026] The oil level in the oil tank of the EFK texturing machine head is monitored in real time by a float and a capacitive sensor, and the change in oil level is converted into an electrical signal. The detected signal is filtered and amplified and compared with a preset threshold such as the minimum oil level. When the machine experiences oil shortage or leakage, or even when the oil valve switch is forgotten to be opened during machine maintenance, the alarm LED of the machine head will flash when the oil level is lower than the preset threshold. In severe cases, it will be upgraded to a continuous alarm.

[0027] When the capacitive sensor malfunctions, such as open circuit or short circuit, it outputs a fault code to avoid false alarms or missed alarms; by setting an oil-proof, oleophobic, and corrosion-resistant coating, it ensures that the float, capacitive sensor, etc., which come into contact with oil are not corroded and damaged; and by using a low-power chip and intermittent wake-up mode, it ensures long-term stable operation.

[0028] The fixing rod has several guide grooves 26 inside, preferably, such as Figure 4As shown, in this embodiment, there is one guide groove 26. The sealing cover plate 21 has a number of guide holes that are the same as the number of guide grooves 26 and are aligned with the guide grooves 26. A locking block 27 is slidably connected inside the guide groove 26. A telescopic groove 32 is opened inside the locking block 27. A pressing rod 33 is fixedly connected to the inner wall of the guide hole. A spring 34 is connected between the telescopic groove 32 and the pressing rod 33. When the locking block 27 leaves the guide groove 26, the guide rod can slide along the length direction of the slot 25. When working, when the locking block 27 is pressed and slides into the guide hole, the pressing rod 33 is inserted into the telescopic groove 32 and the spring 34 is compressed to generate elastic force. When it is necessary to disassemble the sealing tube 23, the guide rod 29 and the guide block 28 are slid out from the inside of the fixed rod by pulling the guide plate 31. Then the spring 34 generates elastic force to push the pressing rod 33, which drives the locking block 27 to slide out from the inside of the guide hole. The sealing tube 23 is disassembled by pulling the fixed rod.

[0029] Furthermore, such as Figures 3-4 As shown, the guide rod 29 has a cavity 41 inside, and guide holes 42 are opened at both ends inside the guide rod 29, which communicate with the cavity 41. The bottom of the guide plate 31 is hinged to a limit rod 45 by a torsion spring. A limit ring 46 is fixed to the inner side wall of the fixed rod. A pull rod 44 is raised and lowered at the top of the guide plate 31. A pull rope 43 is fixed to the bottom of the pull rod 44, and the other end of the pull rope 43 is fixed to the end of the limit rod 45 and passes through the inside of the guide hole 42. During operation, when the guide block 28 is inserted into the fixed rod, it drives the guide plate 31 to fit against the surface of the mounting plate 24, and then pulls... The movable pull rod 44 drives the pull rope 43 to pull the limit rod 45 to rotate and fit against the inner wall of the guide rod 29. When the limit rod 45 passes the limit ring 46, the pull rod 44 is released, and the limit rod 45 unfolds through the elastic force generated by the torsion spring to lock into the bottom of the limit ring 46 for secondary limiting, thereby improving the locking effect of the fixing rod and the installation stability of the sealing tube 23. When disassembly is required, the pull rod 44 is pulled to control the pull rope 43 to pull the limit rod 45 to rotate, and the limit rod 45 disengages from the limit ring 46, so that the fixing rod can be disassembled.

[0030] Furthermore, such as Figures 3-4 As shown, a sealing plate 5 is fixed to the bottom of the guide plate 31 and fits against the top of the fixing rod. During operation, the sealing plate 5 installed at the bottom of the guide plate 31 seals the top gap of the fixing rod, reducing the problem of external dust entering the interior of the fixing rod through the gap and causing corrosion.

[0031] like Figures 3-5As shown, the end of the locking block 27 is semi-arc and matches the guide hole; the end of the guide block 28 is provided with several arc-shaped grooves, which are arranged around the end face of the guide block 28. Preferably, in this embodiment, the arc-shaped grooves include two arranged vertically. During operation, by providing arc-shaped grooves on the surface of the guide block 28, the guide block 28 is less likely to get stuck when pressing the locking block 27.

[0032] Working principle: When the oil level alarm body 22 needs to be installed, the oil level alarm body 22 is installed on top of the sealing cover 21, and then the mounting plate 24 is driven to fit against the top of the sealing cover 21. Then, the fixing rod is inserted into the inside of the slot 25, and then the guide plate 31 is pushed to drive the guide rod 29 and the guide block 28 into the inside of the fixing rod to squeeze the end of the locking block 27. Figure 5 The locking block 27 shown has a chamfer to facilitate the pressing and movement of the guide block. This allows the locking block 27 to slide to both sides under pressure and insert into the guide hole for locking and fixing, enabling quick installation of the sealing tube 23. The sealing tube 23 then monitors the oil level inside the tank body 1. When the oil level is below a certain threshold, the sealing tube 23 triggers an alarm. The locking insertion method makes installation of the sealing tube 23 convenient for the user. When the locking block 27 slides into the guide hole under pressure, the pressing rod 33 inserts into the telescopic groove 32, compressing the spring 34 and generating elastic force. When the sealing tube 23 needs to be disassembled, pulling the guide plate 31 causes the guide rod 29 and guide block 28 to slide out from the fixed rod. Then, the spring 34 generates elastic force to push the pressing rod 33, causing the locking block 27 to slide out from the guide hole. This allows the sealing tube 23 to be disassembled by pulling the fixed rod. When the guide block 28 is inserted into the fixed rod, ... The guide plate 31 is brought into contact with the surface of the mounting plate 24. Then, the pull rod 44 is pulled, which drives the pull rope 43 to pull the limit rod 45 to rotate and fit against the inner wall of the guide rod 29. The spring force generated by the torsion spring allows the limit rod 45 to pass the limit ring 46. Then, by releasing the pull rod 44, the limit rod 45 is unfolded by the spring force generated by the torsion spring, and it is locked at the bottom of the limit ring 46 for secondary limiting, thereby improving the locking effect of the fixing rod and improving the installation stability of the sealing tube 23. When disassembly is required, the pull rod 44 is pulled to control the pull rope 43 to pull the limit rod 45 to rotate, thereby disassembling the fixing rod. A sealing plate 5 is installed at the bottom of the guide plate 31 to seal the top gap of the fixing rod, reducing the problem of external dust entering the interior of the fixing rod through the gap and causing corrosion. An arc groove is opened on the surface of the guide block 28 so that the guide block 28 will not get stuck when pressing the locking block 27.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
