Description

Technical Field

[0001] The invention relates to the technical field of polyester fiber processing, in particular to an instrument for synchronously detecting online tension and oil content of polyester fibers. Background Art

[0002] Polyester fiber, full name polyethylene terephthalate fiber (PET), is a synthetic fiber made from polyester chips made by the condensation reaction of organic dibasic acids and diols, and then processed through melt spinning, post-processing and other processes. During the polyester fiber production process, various fiber indicators such as linear density, strength, elongation, oil content, tension, etc. directly affect subsequent processing and final product performance.

[0003] However, the prior art still has the following problems:

[0004] First, the detection efficiency and accuracy of most existing polyester fiber online detection devices need to be improved. Existing equipment can often only perform single-index detection of tension or oil content, or requires the two detections to be performed in steps, which makes the entire detection process time-consuming and lengthy, seriously restricting production efficiency. In addition, the layout of its detection device is not scientific enough, the accuracy of the detection elements is limited, and it is easily interfered by external factors during long-term operation, resulting in large errors in the detection data and an inability to provide accurate and reliable quality feedback for production.

[0005] Secondly, the versatility and adaptability of the equipment are not high. The structural design of traditional testing equipment is relatively fixed and lacks adjustment mechanisms such as servo motor drive. When faced with polyester fibers with different linear densities and different production process requirements, it is difficult to flexibly adjust the testing position and testing conditions. This results in the same equipment being unable to meet diverse production needs. When companies produce products of different specifications, they often need to replace equipment or invest a lot of money in modifications, which greatly limits the application scope of the equipment.

[0006] In addition, the stability of fiber transportation and detection is poor. The existing equipment has defects in the design of the fiber transportation system and lacks effective limiting and stabilizing devices. During high-speed transportation, polyester fibers are prone to deviation, jitter, and even entanglement. These problems not only affect the smooth progress of the detection, but also cause large fluctuations in the test results.

[0007] In response to the above problems, the inventors proposed a synchronous detector for online tension and oil content of polyester fibers to solve the above problems. Summary of the Invention

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example: Figure 1-8 As shown, the present invention provides a synchronous detector for online tension and oil content of polyester fiber, including a bracket 1, an output shaft 2, a transmission shaft 3, an adjustment shaft 5 and two parallel shafts 6 are provided on the upper side of the bracket 1, and an oil content detector 72 is provided between the two parallel shafts 6, a pressure roller 4 is provided on the upper side of the transmission shaft 3, a tension detector 71 is fixedly provided on the upper surface of the adjustment shaft 5, a control box 7 is fixedly provided in the bracket 1, and the control box 7 is communicatively connected with the tension detector 71 and the oil content detector 72, the bracket 1 serves as the basic support structure of the entire detector, and provides an installation platform for other components. The output shaft 2, the transmission shaft 3, the adjustment shaft 5 and the two parallel shafts 6 constitute the path framework for fiber transportation and detection. The oil content detector 72 is installed between the two parallel shafts 6 to detect the oil content of the fiber; the pressure roller 4 is located on the upper side of the transmission shaft 3 to assist in fiber transportation and provide a certain pressure; the tension detector 71 is set on the adjustment shaft 5 to monitor the fiber tension in real time; the control box 7 receives the data signals of the tension detector 71 and the oil content detector 72, and after analysis and processing, it can control the relevant components to adjust the operating parameters to achieve synchronous detection and regulation of the tension and oil content of the polyester fiber.

[0033] The upper surface of the bracket 1 is symmetrically connected to the support seat 21 by bolts, and the upper surface of the support seat 21 is provided with a slot 22, and the output shaft 2 is clamped in the two slots 22. A guard plate 23 is fixedly provided on one side of the bracket 1, and a first servo motor 24 is fixedly provided on the upper surface of the guard plate 23. The output end of the first servo motor 24 is inserted into one end of the output shaft 2, and the output shaft 2 and the output end of the first servo motor 24 are connected by bolts. A limit plate 25 is symmetrically fixed on the outer surface of the output shaft 2. The support seat 21 is fixed to the bracket 1 by bolts, and its slot 22 plays a positioning and supporting role for the output shaft 2 to ensure that the output shaft 2 is stably installed. The guard plate 23 is used to protect the first servo motor 24. After the first servo motor 24 is started, its output end drives the output shaft 2 to rotate. The two are connected by bolts to ensure effective power transmission. The limit plate 25 on the outer surface of the output shaft 2 can prevent the polyester fiber from deviating to both sides during the conveying process, ensuring that the fiber is conveyed along the predetermined path, providing stable fiber conveying conditions for subsequent detection processes.

[0034] The upper surface of the bracket 1 is symmetrically connected with a vertical plate 31 by bolts. The transmission shaft 3 is rotatably set between the two vertical plates 31. A shell 32 is provided on the outside of one of the vertical plates 31, and the lower surface of the shell 32 is connected to the bracket 1 by bolts. Two sprockets 33 are rotatably provided in the shell 32, and the outer surface of the sprocket 33 is meshed with a chain 34. A second servo motor 35 is fixed on one side of the bracket 1. The output end of the second servo motor 35 is fixedly connected to one of the sprockets 33. One end of the transmission shaft 3 passes through the vertical plate 31 and is connected to the other. The two sprockets 33 are fixedly connected, and the vertical plate 31 is fixed on the bracket 1 to provide rotation support for the transmission shaft 3. After the second servo motor 35 is started, it drives the sprocket 33 connected to it to rotate. Through the transmission of the chain 34, the other sprocket 33 rotates synchronously, thereby driving the transmission shaft 3 to rotate. The shell 32 protects the internal sprocket 33 and chain 34 to prevent dust and other impurities from entering and affecting the transmission effect. This transmission structure realizes the transmission of power from the second servo motor 35 to the transmission shaft 3, providing rotational power for the pressure roller 4, and assisting in the transportation and compression of polyester fibers.

[0035] A support slider 41 is provided on the upper surface of the vertical plate 31, and the pressure roller 4 is rotatably set between the two support sliders 41. The upper surface of the support slider 41 is symmetrically and movably inserted with a plug-in column 42, and the lower end of the plug-in column 42 is fixed with a screw column 43, and the screw column 43 is threadedly inserted into the upper end of the corresponding vertical plate 31. A limit block 44 is fixed on the upper end of the plug-in column 42, and a spring 45 is fixedly connected between the limit block 44 and the corresponding support slider 41. The support slider 41 supports the pressure roller 4 so that it can rotate freely. The screw column 43 is screwed with the vertical plate 31. The height of the support slider 41 can be adjusted by rotating the wire column 43, thereby adjusting the contact pressure between the pressure roller 4 and the fiber. The plug column 42 and the limit block 44 limit and guide the movement of the support slider 41 to prevent it from deflecting. The setting of the spring 45 enables the pressure roller 4 to adaptively adjust the pressure according to the characteristics of the fiber. When the fiber thickness and other characteristics change, the spring 45 compresses or extends to ensure that the pressure roller 4 can effectively press the fiber to assist in transportation without damaging the fiber due to excessive pressure, thereby ensuring that the fiber state is stable during the detection process.

[0036] An adjustment frame 55 is fixed on the upper surface of the bracket 1, and a lifting block 51 is symmetrically slidably provided in the adjustment frame 55. The adjustment shaft 5 is fixedly provided between the two lifting blocks 51. A third servo motor 52 is fixed on the upper surface of the adjustment frame 55, and the output end of the third servo motor 52 passes through the adjustment frame 55 and is fixedly connected to a lead screw 53. The lead screw 53 is rotatably provided in the adjustment frame 55, and the lead screw 53 threadably passes through one of the lifting blocks 51. A limiting column 54 is fixed in the adjustment frame 55, and the limiting column 54 passes through one of the lifting blocks 51. The outer side of the lifting block 51 is clamped on the inner wall of the adjustment frame 55. After the third servo motor 52 is started, it drives the screw 53 to rotate. Since the screw 53 is threadedly connected to one of the lifting blocks 51, under the guidance and limiting action of the limit column 54, the lifting block 51 slides up and down along the inner wall of the adjustment frame 55, thereby driving the adjustment shaft 5 to rise and fall. By adjusting the height of the adjustment shaft 5, it can adapt to polyester fibers of different specifications, ensuring that the tension detector 71 performs tension detection on the fiber at the appropriate position, thereby improving the accuracy and applicability of the detection.

[0037] A transverse plate 8 is symmetrically fixed on the upper surface of the bracket 1, and a guide rail 81 is fixed on the inner side of the transverse plate 8. An electric slider 82 is slidably provided on the inner side of the guide rail 81. The transverse plate 8 is fixedly installed on the bracket 1 to provide a stable installation basis for the guide rail 81. The guide rail 81 and the electric slider 82 cooperate with each other. The electric slider 82 can slide on the guide rail 81, thereby providing guidance and support for the horizontal movement of the oil content detector 72. By controlling the sliding of the electric slider 82, the oil content detector 72 can be moved to different positions in the horizontal direction, thereby realizing the detection of the oil content of different parts of the fiber, and improving the comprehensiveness and flexibility of the detection.

[0038] A moving plate 83 is fixedly connected between the two electric sliders 82, and a moving block 84 is slidably provided on the upper surface of the moving plate 83. A fourth servo motor 85 is fixedly provided on one side of the moving block 84, and the output end of the fourth servo motor 85 is fixedly connected to a driving gear 86. A toothed plate 88 is fixedly provided on one side of the moving plate 83, and the toothed plate 88 is meshed with the driving gear 86. A T-shaped slider 87 is fixedly provided on the lower surface of the moving block 84, and the T-shaped slider 87 is clamped in the moving plate 83. After the fourth servo motor 85 is started, it drives the driving gear 86 to rotate. Since the toothed plate 88 is fixed on the moving plate 83, when the driving gear 86 is meshed with the toothed plate 88, under the meshing force, the moving block 84 slides on the moving plate 83 through the T-shaped slider 87. By controlling the rotation of the fourth servo motor 85, the oil content detector 72 can be more accurately adjusted in the horizontal direction, and the oil content can be detected at different positions of the fiber, thereby further improving the detection accuracy.

[0039] A support plate 9 is fixed to one side of the moving block 84, and a crown gear 91 is provided on the lower side of the support plate 9. An L-shaped plate 92 is fixed to one side of the lower surface of the support plate 9, and a fifth servo motor 93 is fixed to the upper surface of the L-shaped plate 92. The output end of the fifth servo motor 93 passes through the L-shaped plate 92 and is fixed with a spur gear 94, and the spur gear 94 is meshed with the crown gear 91. A column 99 is fixed to the upper surface of the crown gear 91, and the upper end of the column 99 passes through the support plate 9 and is fixed with a turntable 95. A support rod 96 is fixed to the upper surface of the turntable 95, and one side of the support rod 96 is detachably connected to the oil content detector 72. After the fifth servo motor 93 is started, it drives the spur gear 94 to rotate, and the spur gear 94 engages with the crown gear 91, causing the crown gear 91 to rotate around its axis. The crown gear 91 drives the turntable 95 and the support rod 96 to rotate through the column 99, thereby realizing the angle adjustment of the oil content detector 72 in the vertical plane. By controlling the rotation angle and direction of the fifth servo motor 93, the oil content detector 72 can detect fibers from different angles, thereby improving the comprehensiveness and accuracy of the detection. At the same time, the detachable connection between the support rod 96 and the oil content detector 72 facilitates quick operation when maintaining, calibrating or replacing the detector.

[0040] A mounting groove 97 is provided on the upper surface of the support rod 96, and a mounting rod 98 is fixedly provided on one side of the oil content detector 72, and the mounting rod 98 is clamped in the mounting groove 97. The mounting rod 98 and the mounting groove 97 are connected by bolts. The cooperation between the mounting rod 98 and the mounting groove 97 realizes the preliminary positioning of the oil content detector 72 and the support rod 96, ensuring that the detector is installed in an accurate position. On this basis, the mounting rod 98 and the mounting groove 97 are fixedly connected by bolts, further ensuring that the oil content detector 72 is firmly installed on the support rod 96. The oil content detector 72 adopts a detachable installation method, and the bolt connection between the mounting rod 98 and the mounting groove 97 facilitates maintenance, calibration and replacement of the detection instrument, thereby reducing the maintenance cost and difficulty of the equipment; the modular design of each component also facilitates the overall inspection and upgrade of the equipment.

[0041] Among them, the first servo motor 24, the second servo motor 35, the third servo motor 52, the fourth servo motor 85, the fifth servo motor 93, the electric slider 82, the tension detector 71 and the oil content detector 72 are existing technologies and will not be described in detail; at the same time, the present invention also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail.

[0042] Working principle: The first servo motor 24 starts, driving the output shaft 2 to rotate. The limit plate 25 on the output shaft 2 prevents the polyester fiber from deviating during the conveying process. The output shaft 2 transmits power to the subsequent transmission components, causing the polyester fiber to begin to be conveyed. The second servo motor 35 drives the sprocket 33 to rotate, which drives the transmission shaft 3 to rotate through the chain 34, and then drives the pressure roller 4 to rotate, conveying and initially compacting the polyester fiber.

[0043] During the conveying process, the polyester fiber passes through the adjustment shaft 5. The tension detector 71 on the adjustment shaft 5 detects the tension of the fiber in real time. The third servo motor 52 can adjust the height of the lifting block 51 through the screw 53, thereby adjusting the height of the adjustment shaft 5 to adapt to the tension detection position requirements of polyester fibers of different specifications, ensuring the accuracy of tension detection.

[0044] The oil content detector 72 between the two parallel shafts 6 detects the oil content of the polyester fiber. The fourth servo motor 85 drives the drive gear 86 to rotate. The drive gear 86 engages with the tooth plate 88, causing the moving block 84 to slide on the moving plate 83. At the same time, the fifth servo motor 93 drives the spur gear 94 to rotate. The spur gear 94 engages with the crown gear 91, causing the crown gear 91 to rotate. The turntable 95 and the support rod 96 are then driven to rotate through the column 99, thereby adjusting the position of the oil content detector 72 in the horizontal and vertical directions. The oil content detector can detect the oil content of fibers at different positions. The cooperation between the mounting rod 98 and the mounting slot 97 facilitates the removal and installation of the oil content detector 72.

[0045] The tension detector 71 and the oil content detector 72 transmit the detected data to the control box 7, which analyzes and processes the data and determines whether the tension and oil content of the polyester fiber are qualified according to the preset parameter range. It can also issue control instructions to each servo motor as needed to adjust the equipment operating parameters to ensure the production quality of the polyester fiber.

[0046] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
