Description

Technical Field

[0001] This utility model relates to the field of roving frame technology, and in particular to a roving length testing device for roving frames. Background Technology

[0002] In the roving production process of the textile industry, precise control of roving length plays a crucial role in production efficiency and product quality. However, existing roving length testing methods have many problems and are difficult to meet production needs.

[0003] Currently, the length measurement of roving frames is usually measured in meters. However, in actual production, the length of roving varies significantly between different frames, with differences exceeding ten meters per frame. Various methods used in the industry to identify these length discrepancies have their drawbacks. One common method is to weigh the entire roving to compare differences, but due to the inherent uneven weight distribution of the roving itself, this method cannot accurately control the length to within 20 meters, failing to meet the requirements of precision production. Another method is to hang the roving on the spinning frame to measure the length. However, this method is not only time-consuming, severely impacting production progress, but also highly dependent on the operating status of the equipment. Different operating conditions at different times lead to large fluctuations in measurement results, making precise length control impossible and resulting in significant raw material waste and increased production costs.

[0004] While existing technologies exist for detecting and controlling textile equipment, most focus on yarn quality inspection and equipment operation status monitoring, with few specifically optimized for roving length testing. These technologies fail to effectively address the issues of large variations in roving length and inaccurate measurements, leading to problems such as unstable product quality and low production efficiency for textile companies. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing roving frames, such as low roving length accuracy, which makes it difficult to meet the requirements of fine production, and to provide a roving length testing device for roving frames.

[0006] This utility model is achieved through the following technical solution: a roving length testing device for a roving frame, comprising a sensing probe, a telescopic arm, and a base; the base is fixed to the roving frame frame by bolts, and the base is located near the tail end of the front roller of the roving frame; a rotating mechanism is provided on the base, and the rotating mechanism is connected to a lifting unit, which can be rotated through the rotating mechanism; the lifting unit is connected to a rotating mechanism, which can be raised and lowered through the lifting unit; the rotating mechanism is connected to a telescopic arm, which can be rotated through the rotating mechanism; the telescopic arm is connected to a sensing probe, which can be extended and retracted through the telescopic arm; the sensing probe is used to test the rotation number of the front roller, and the sensing probe is connected to an external counter through a data cable. This utility model achieves multi-dimensional flexible adjustment of the sensing probe through the coordinated operation of multiple mechanisms, which facilitates accurate testing of the front roller rotation number and is applicable to different roving frames.

[0007] A further improvement of this utility model is that the rotating mechanism includes a support shaft, with support plates at both ends of the support shaft, and the support shaft is fixed to the base via the support plates. A rotating tube is mounted on the support shaft via a bearing rotating sleeve, located between the two support plates. A positioning bolt A is screwed onto the rotating tube, and the positioning bolt A can penetrate into the interior of the rotating tube and press against the outer wall of the support shaft, thereby fixing the position of the rotating tube. A support arm is connected to the rotating tube, and the rotating tube is connected to the lifting unit via the support arm. The rotating mechanism can stably rotate and fix the angle, ensuring stable testing and allowing for flexible adjustment of the sensor probe position.

[0008] A further improvement of this utility model is that the lifting unit includes a fixed plate, one side of which is connected to a support arm, and the other side of the fixed plate is provided with a slide groove. A screw is rotatably mounted inside the slide groove, one end of which rotates out of the slide groove and then connects to a knob after rotating out of the fixed plate. A movable slider located inside the slide groove is screwed onto the screw, the outer wall of which slides in contact with the inner wall of the slide groove, and the movable slider is connected to a rotating mechanism. This lifting unit allows for precise height adjustment, facilitating the proximity of the sensing probe to the front roller, thus improving testing accuracy and ease of use.

[0009] A further improvement of this invention is that pulleys are respectively provided on the outer walls of both sides of the movable slider, and the pulleys slide in contact with the inner wall of the groove. The pulleys reduce friction, making the moving slider rise and fall more smoothly, ensuring the stability of the sensing probe, and extending the life of the device.

[0010] A further improvement of this invention is that the rotating mechanism includes a support tube fixed to the movable slider. A rotating column is rotatably mounted inside the support tube, and the rotating column is connected to a telescopic arm. A positioning bolt B is screwed onto the support tube. The positioning bolt B can penetrate into the support tube and press against the outer wall of the rotating column, thereby fixing the position of the rotating column. This rotating mechanism allows the sensing probe to rotate flexibly and be fixed, expanding the testing angle and making it suitable for complex spaces.

[0011] A further improvement of this invention is that the rotating column is movably disposed inside the support tube, with the outer wall of the rotating column slidingly contacting the inner wall of the support tube; one end of the support tube is connected to a movable slider, and the other end of the support tube is screwed with a sealing cap for sealing the rotating column, and the sealing cap is provided with an assembly hole through which the telescopic arm can pass. The design of the rotating column and the sealing cap ensures smooth rotation, prevents foreign objects from entering, and ensures the stability and reliability of the device.

[0012] A further improvement of this invention is that the telescopic arm includes an outer tube and an inner tube. One end of the outer tube is detachably connected to the sensing probe via a connector assembly, and the other end of the outer tube is slidably inserted into the inner tube. One end of the inner tube is slidably inserted into the interior of the outer tube, and the other end of the inner tube is connected to a rotating column. A positioning bolt C is screwed onto the outer tube. The positioning bolt C can penetrate into the interior of the outer tube and press against the outer wall of the inner tube, thereby fixing the position of the outer tube. The telescopic arm is length-adjustable, precisely controlling the distance between the sensing probe and the front roller, thus improving testing accuracy.

[0013] Further improvements to this invention include that both the outer and inner tubes are hollow square tubes. The inner wall of the outer tube has reinforcing ribs, and the outer wall of the inner tube has reinforcing grooves corresponding to the reinforcing ribs. Furthermore, the side wall of the inner tube that contacts the positioning bolt C is thickened. This special tube material and reinforced design enhance the strength of the telescopic arm, ensuring stable and accurate testing and extending its service life.

[0014] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0015] 1. This invention uses the roving roller rotation speed as the measurement benchmark and combines it with the roller diameter to calculate the roving length, thus overcoming the problem of large length discrepancies caused by the previous method of counting in meters. By testing and correcting each roving frame individually, the length discrepancy can be precisely controlled, significantly improving the accuracy of roving length setting, ensuring product quality stability, and reducing subsequent production problems caused by length discrepancies.

[0016] 2. The sensing probe, telescopic arm, rotating mechanism, lifting unit, and slewing mechanism of this invention work together to flexibly adjust the position in multiple dimensions, making it easy to operate and highly adaptable. Operators can easily adjust the sensing probe to the optimal testing position. This device is applicable to different models of roving machines and complex spatial environments around the front roller, greatly improving the convenience and versatility of testing and reducing the difficulty and labor intensity of the operator's work.

[0017] 3. The components of this utility model employ reasonable design and material selection, such as the reinforcing ribs and thickened wall design of the telescopic arm, as well as the fastening methods of each connecting component, effectively enhancing the overall structural strength.

[0026] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0027] Please refer to the attached document. Figure 1 The following is a description of a specific embodiment: The roving length testing device for a roving frame according to this utility model includes a sensing probe 1, a telescopic arm 2, and a base 6. The base 6 is fixed to the roving frame 7 by bolts, and is located near the tail end of the front roller of the roving frame. A rotating mechanism 5 is provided on the base 6, and a lifting unit 4 is connected to the rotating mechanism 5. The lifting unit 4 can be rotated via the rotating mechanism 5. A rotating mechanism 3 is connected to the lifting unit 4, and the rotating mechanism 3 can be raised and lowered via the lifting unit 4. The rotating mechanism 3 is connected to the telescopic arm 2, and the telescopic arm 2 can be rotated via the rotating mechanism 3. The sensing probe 1 is connected to the telescopic arm 2, and the sensing probe 1 can be extended and retracted via the telescopic arm 2. The sensing probe 1 is used to test the number of revolutions of the front roller, and the sensing probe 1 is connected to an external counter via a data cable.

[0028] The working principle of this invention is based on the coordinated operation of multiple components to flexibly adjust the position of the sensing probe 1 for accurate testing of the front roller rotation. The base 6 is bolted to the roving frame 7 near the tail end of the front roller, providing stable support for the entire device. The rotary mechanism 5, lifting unit 4, rotating mechanism 3, and telescopic arm 2 are connected sequentially, allowing the sensing probe 1 to be flipped, lifted, rotated, and extended / retracted. The sensing probe 1 measures the rotation of the front roller by sensing its rotation and transmits the data to an external counter via a data cable. This device not only adapts to the position and spatial layout of the front roller on different roving frames, improving the versatility and flexibility of the test, but also ensures that the sensing probe 1 is precisely positioned near the front roller, greatly improving the accuracy of roving length testing.

[0029] Among them, refer to the appendix Figure 4 The rotary mechanism 5 includes a support shaft 501, with support plates 502 at both ends of the support shaft 501. The support shaft 501 is fixed to the base 6 via the support plates 502. A rotating tube 503 is mounted on the support shaft 501 via a bearing rotating sleeve, located between the two support plates 502. A positioning bolt A504 is screwed onto the rotating tube 503. The positioning bolt A504 can penetrate into the interior of the rotating tube 503 and press against the outer wall of the support shaft 501, thereby fixing the position of the rotating tube 503. A support arm 505 is connected to the rotating tube 503, and the rotating tube 503 is connected to the lifting unit 4 via the support arm 505.

[0030] The rotating mechanism 5 utilizes the principle that the rotating tube 503 on the support shaft 501 can rotate around the shaft, and uses positioning bolts A504 to fix the position of the rotating tube 503. Both ends of the support shaft 501 are fixed to the base 6 via support plates 502. The rotating tube 503 is fitted onto the support shaft 501 and can rotate freely. When the rotating tube 503 rotates to a suitable angle, the positioning bolts A504 are tightened to press against the outer wall of the support shaft 501, thereby fixing the rotating tube 503. The rotating tube 503 is connected to the lifting unit 4 via a support arm 505, causing the lifting unit 4 to rotate. This design allows for flexible adjustment of the angle of the lifting unit 4 according to the actual situation of the roving machine, ensuring the induction probe 1 is in the optimal testing position, while also guaranteeing the stability of the device during testing and avoiding impact on testing accuracy due to shaking.

[0031] Among them, refer to the appendix Figure 2The lifting unit 4 includes a fixed plate 401, one side of which is connected to the support arm 505, and the other side of the fixed plate 401 is provided with a slide groove 402. A screw 403 is rotatably installed inside the slide groove 402. One end of the screw 403 rotates out of the slide groove 402 and then rotates out of the fixed plate 401 before connecting to a knob 405. A movable slider 404 located inside the slide groove 402 is screwed onto the screw 403. The outer wall of the movable slider 404 slides in cooperation with the inner wall of the slide groove 402, and the movable slider 404 is connected to the rotating mechanism 3.

[0032] The lifting unit 4 can rotate the screw 403 by turning the knob 405. The screw 403 is screwed to the movable slider 404. When the screw 403 rotates, the movable slider 404 moves up and down within the slide groove 402. The operator can precisely control the raising and lowering of the movable slider 404 by rotating the knob 405, thereby adjusting the height of the sensing probe 1. This design allows the sensing probe 1 to be precisely positioned near the front roller, avoiding testing errors caused by improper height. Furthermore, it is simple and convenient to operate, improving testing efficiency and accuracy.

[0033] Among them, refer to the appendix Figure 3 The rotating mechanism 3 includes a support tube 301, which is fixed to the movable slider 404. A rotating column 302 is rotatably arranged inside the support tube 301. The rotating column 302 is connected to the telescopic arm 2, and a positioning bolt B304 is screwed onto the support tube 301. The positioning bolt B304 can penetrate into the support tube 301 and press against the outer wall of the rotating column 302, thereby fixing the position of the rotating column 302.

[0034] When the angle of the sensing probe 1 needs to be adjusted, loosen the positioning bolt B304, and the rotating column 302 can rotate freely within the support tube 301. After adjusting to the appropriate angle, tighten the positioning bolt B304 to fix it. This design allows the sensing probe 1 to approach the front roller from different angles, adapting to the complex spatial environment around the front roller, expanding the application scenarios of the device, and improving the flexibility of testing.

[0035] Among them, refer to the appendix Figure 3 The telescopic arm 2 includes an outer tube 201 and an inner tube 202. One end of the outer tube 201 is detachably connected to the sensing probe 1 via a connector assembly, and the other end of the outer tube 201 is slidably inserted into the inner tube 202. One end of the inner tube 202 is slidably inserted into the interior of the outer tube 201, and the other end of the inner tube 202 is connected to the rotating column 302. A positioning bolt C203 is screwed onto the outer tube 201. The positioning bolt C203 can penetrate into the interior of the outer tube 201 and press against the outer wall of the inner tube 202, thereby fixing the position of the outer tube 201.

[0036] When it is necessary to adjust the distance between the sensor probe 1 and the front roller, loosen the positioning bolt C203, slide the outer tube 201, adjust it to the appropriate position, and then tighten the positioning bolt C203. This design can precisely control the distance between the sensor probe 1 and the front roller, avoiding the impact of improper distance on the test accuracy. At the same time, it can prevent the sensor probe 1 from colliding and being damaged by the front roller, thus improving the accuracy of the test and the applicability of the device.

[0037] In one embodiment, reference is made to the appendix. Figure 2 The two outer walls of the movable slider 404 are respectively provided with pulleys 406, and the pulleys 406 slide in contact with the inner wall of the groove 402.

[0038] During the lifting and lowering process of the movable slider 404, the pulley 406 plays an auxiliary role. When the movable slider 404 slides within the groove 402 under the drive of the screw 403, the pulley 406 reduces the friction between the movable slider 404 and the inner wall of the groove 402. This design makes the lifting and lowering process of the movable slider 404 smoother and more stable, reduces wear on components, extends the service life of the device, and ensures the stability of the position of the sensing probe 1 during the lifting and lowering process, further improving the testing accuracy.

[0039] In one embodiment, reference is made to the appendix. Figure 3 The rotating column 302 is movably disposed inside the support tube 301, and the outer wall of the rotating column 302 slides in contact with the inner wall of the support tube 301; one end of the support tube 301 is connected to the movable slider 404, and the other end of the support tube 301 is screwed with a sealing cover 303 for sealing the rotating column 302, and the sealing cover 303 is provided with an assembly hole that can pass through the telescopic arm 2.

[0040] The outer wall of the rotating column 302 slides in contact with the inner wall of the support tube 301, allowing it to rotate freely within the support tube 301. The sealing cap 303 prevents dust and debris from entering the support tube 301 and affecting the rotation of the rotating column 302, and the mounting holes on the sealing cap 303 allow the telescopic arm 2 to pass through smoothly. This design ensures the smooth rotation of the rotating column 302 while improving the sealing and stability of the device, thus contributing to the overall reliability and service life of the device.

[0041] In one embodiment, reference is made to the appendix. Figure 5 and 6 Both the outer tube 201 and the inner tube 202 are hollow square tubes. The inner wall of the outer tube 201 is provided with reinforcing ribs 2011, and the outer wall of the inner tube 202 is provided with reinforcing grooves 2022 corresponding to the reinforcing ribs 2011. The side wall of the inner tube 202 that contacts the positioning bolt C203 is thickened.

[0042] The reinforcing rib 2011 and the reinforcing groove 2022 work together to enhance the structural strength of the telescopic arm 2. Simultaneously, the thickened side wall of the inner tube 202 where it contacts the positioning bolt C203 further improves the compressive strength of the telescopic arm 2. During frequent extension, retraction, and adjustment of the telescopic arm 2, this design effectively prevents deformation, ensuring the stability of the sensor probe 1's position, thereby improving testing accuracy, extending the service life of the telescopic arm 2, and reducing maintenance costs.

[0043] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
