Technical Field

[0001] The utility model belongs to the technical field of glass fiber cloth production, and particularly relates to a safety protection device for a glass fiber yarn warping machine. Background Art

[0002] Warping is an important part of the glass fiber cloth production process. The warping machine is used to organize the glass fiber raw yarn into warp yarn packages to prepare for the subsequent sizing and weaving processes. The warp yarn is wound by the warping shaft of the warping machine. After winding, it enters the sizing process and the warping machine is replaced with a new warping shaft. In the existing technology, the warping shaft of the warping machine is usually set at the outermost side of the frame and driven by a motor to rotate at high speed. However, due to the lack of safety protection devices, there are huge safety hazards in the working state. If the operator touches the warping shaft by negligence, it is easy to be scratched by it, or even in danger of being entangled by the warping shaft. Therefore, the existing warping machine structure is further improved, and a safety protection device for a glass fiber yarn warping machine is proposed. Utility Model Content

[0003] In response to the deficiencies in the background technology, the utility model provides a safety protection device for a glass fiber yarn warping machine. By adding a freely flippable protection rod on the outside of the warping shaft, the protection rod can be used to prevent the operator from accidentally touching the warping shaft. At the same time, the protection rod can be freely flipped, thereby ensuring the normal disassembly and assembly of the warping shaft.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] In the description of the present invention, it should be understood that the terms "middle", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0027] In this utility model, unless otherwise specified or limited, the terms "disposed," "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed or detachable connections, mechanical connections, direct connections, or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0028] like Figures 1 to 3As shown, a safety protection device for a glass fiber yarn warping machine includes a warping shaft 1 and two frame seats 2. The warping shaft is located between the two frame seats and is rotatably connected to the two frame seats. A swing arm 3 is rotatably connected to the side of each frame seat close to the warping shaft. A protection rod 4 is connected between the ends of the two swing arms. By adjusting the angle of the swing arm, the position of the protection rod can be adjusted to change its positional relationship with the warping shaft. The first support block 5 and the second support block 6 are respectively provided on the side of each frame seat close to the warping shaft. The first support block is located on the outside of the warping shaft, and the second support block is located above the inside of the warping shaft. The rotation angle range of the two swing arms is 0-120°. When the two swing arms are respectively pressed on the two first support blocks, the two swing arms and the protective rod are in the same horizontal plane, that is, the angle between the two swing arms and the horizontal plane is 0°. At this time, the protective rod is located on the outside of the warping shaft, which can play a blocking role to prevent the operator on the outside of the warping shaft from accidentally touching the warping shaft in a high-speed rotating state; when the two swing arms are respectively pressed on the two second support blocks, the two swing arms are flipped inward and upward, so that the two swing arms are in an inclined state. At this time, the angle between the two swing arms and the horizontal plane is 120°, and the protective rod is located above the inside of the warping shaft. In this state, the protective rod will not play a blocking role on the warping shaft, and the warping shaft can be freely disassembled and assembled.

[0029] The first support block and the second support block are made of rubber material, which can play a shock-absorbing role when the protective rod is opened (the protective rod is located above the inner side of the warping beam) or closed (the protective rod is located outside the warping beam). Figure 2 and Figure 7 As shown, the first support block includes a fixed part 501 and a movable part 502. The fixed part is fixedly connected to the frame seat, and the movable part is connected to the swing arm. The movable part is connected in cooperation with the fixing slot 5011 provided at the upper end of the fixed part to ensure the structural stability of the protective rod when it falls.

[0030] like Figure 5 As shown, the protective rod includes a central section 401, and the two ends of the central section are symmetrically connected with a transition section 402 and an end 403. The end and the central section are perpendicular to each other and are detachably connected to the corresponding swing arm. The protective rod of this structure can effectively wrap the warping beam as a whole, thereby improving safety. Figure 6 As shown, the two end caps mate with the sockets 301 provided on the two swing arms, respectively. A locking assembly is provided between the end caps and the swing arms to facilitate assembly, removal, replacement, and maintenance of the protective bar. The locking assembly comprises positioning holes 7 provided on the swing arms and mating holes 8 provided on the end caps. The positioning and mating holes are connected by locking bolts 9, making assembly and removal quick and easy. The number of mating holes is at least two, evenly spaced along the length of the end caps, allowing the distance between the protective bar and the warping beam to be adjusted as needed, thus providing a wide range of applications.

[0031] Combine Figure 3 and Figure 4 As shown, an infrared receiver 10 is installed at the end of one of the swing arms away from the protective rod. The infrared receiver cooperates with an infrared transmitter 11 mounted on the corresponding frame. When the swing arm is bearing pressure on the first support block, the infrared transmitter is located inside the infrared receiver, and the two are located on the same horizontal line. The infrared receiver and infrared transmitter are both electrically connected to the warping machine's control system. When the two swing arms are horizontal, the infrared receiver can receive the signal from the infrared transmitter and feed it back to the control system. The control system analyzes and determines that the protective rod is in a safe protection state, and the warping beam rotates normally. Conversely, when the infrared receiver cannot receive the signal from the infrared transmitter, indicating that the two are not on the same horizontal line, the infrared receiver feeds back the signal to the control system. The control system determines that the swing arm is not horizontal, and the protective rod has not reached the specified position, thus failing to perform its safety protection function. The warping beam cannot rotate or stops rotating, ensuring the personal safety of the operator.

[0032] The working principle of this utility model is as follows:

[0033] like Figure 1 As shown, when the warping machine needs to be started to wind the glass fiber warp yarn 12, the swing arm 3 is rotated to a horizontal state so that the swing arm 3 bears pressure on the first support member 5. At this time, the protective rod 4 is located on the outside of the warping shaft, which can effectively separate the operator from the warping shaft to avoid accidental collision. When the warping machine is finished winding and the warping shaft 1 stops rotating, the operator flips the swing arm 3 upward until it bears pressure on the second support member 6. The protective rod 4 is located above the inside of the warping shaft, allowing the warping shaft to be disassembled, assembled, or replaced. If the infrared transmitter 11 and the infrared receiver 10 work together, safety can be further improved. When the infrared receiver 10 can receive the signal from the infrared transmitter 11, it indicates that the protective rod 4 is playing a safety role; otherwise, the warping shaft 1 cannot rotate or stops rotating.

[0034] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that come within the meaning and range of equivalents of the claims be included in the present invention.
