Description

Technical Field

[0001] This utility model relates to the technical field of rubber roller forming machines, specifically to a three-column rubber roller forming machine. Background Technology

[0002] The bushing roller is a crucial component of spinning machinery and one of the most frequently used parts. Rotating at a certain speed, it grips the cotton yarn or sliver, thus completing the drafting action. This is a key step in ensuring spinning quality, and therefore, the bushing roller has a significant impact on the spinning quality of the machine. The outer surface of the bushing roller is a rubber sleeve that directly contacts the textile, and it wears out relatively quickly. However, the internal iron core and bearings can often be used for a long time. Therefore, the current practice is mostly to remove the outer rubber sleeve from the bearing after it wears out and replace it with a new one for continued use.

[0003] The three-column rubber roller fitting machine is mainly used in the textile industry for fitting rubber rollers and bearings. It accurately presses the rubber roller onto the bearing, ensuring a tight fit and forming a rubber roller assembly that can be installed on spinning equipment. The three-column rubber roller fitting machine improves the motion precision during the fitting process, effectively preventing aluminum-lined rubber roller detachment and mechanical wave phenomena during spinning caused by insufficient fitting precision, thus contributing to improved yarn quality.

[0004] For operational safety, existing three-column rubber roller forming machines typically have a pair of photoelectric sensors installed on both sides of the rubber roller support. These sensors monitor the working area of ​​the telescopic cylinder. After the telescopic cylinder completes one downward press assembly, the worker will inspect the rubber sleeve, roller core, and bearing. If the photoelectric sensor detects any foreign objects at this point, the telescopic cylinder will not open, thus ensuring worker safety. However, the detection range of the photoelectric sensors on existing three-column rubber roller forming machines is relatively small and cannot effectively protect worker safety. Utility Model Content

[0005] To address the technical problem of limited protection range of grating sensors in existing rubber roller forming machines, this invention provides a three-column rubber roller forming machine.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A three-column rubber roller forming machine includes two sensor mounting brackets located on both sides of a rubber roller support. Each sensor mounting bracket has a grating sensor mounted on both sides. Each grating sensor has several detection heads distributed vertically. Two grating sensors on the same side of the two sensor mounting brackets form a group. The detection heads of the grating sensors in the same group are arranged opposite each other and all the detection heads face the rubber roller support. The vertical dimension ratio of the grating sensor to the rubber roller support is greater than 1.3:1.

[0008] The above-described structural design includes grating sensors mounted on both sides of each sensor mounting bracket. Each grating sensor has several detection heads distributed vertically, with the detection heads in the same group facing the rubber roller support. Furthermore, the vertical dimension ratio between the grating sensor and the rubber roller support is greater than 1.3:1. Compared to existing photoelectric sensors with smaller detection ranges, this application significantly expands the monitoring range of the telescopic cylinder's working area, enabling more comprehensive detection of foreign objects that may enter the working area. This effectively prevents workers from being injured by accidental equipment startup when replacing the rubber roller core and bearings, significantly improving operational safety.

[0009] As a preferred implementation of a three-column rubber roller mill, the grating sensor has a vertical dimension of 200mm.

[0010] The above structural design makes the detection range of the grating sensor more specific and quantifiable. In practical applications, 200mm can ensure that the grating sensor has sufficient coverage in the vertical direction, further enhancing the monitoring effect on the working area of ​​the telescopic cylinder and providing more reliable safety protection for the staff.

[0011] As a preferred implementation of a three-column rubber roller mill, each grating sensor is equipped with eight detection heads.

[0012] With the above structural design, each grating sensor is equipped with 8 detection heads, increasing the number of detection points. More detection heads allow for more detailed monitoring of the space around the rubber roller support, enabling timely detection even of small foreign objects entering the working area. This improves detection sensitivity and accuracy, further enhancing the safety of workers.

[0013] As a preferred implementation of a three-column rubber roller machine, the rubber roller bracket is supported by a telescopic cylinder, which passes through the rubber roller bracket. The bottom of the grating sensor is not higher than the top of the rubber roller bracket, and the top of the grating sensor is not lower than the top of the telescopic cylinder.

[0014] By adopting the above structural scheme, the bottom of the grating sensor is limited to not being higher than the top of the rubber roller bracket, and the top is not lower than the top of the telescopic cylinder. This ensures that the grating sensor can monitor the entire working area of ​​the rubber roller bracket and the telescopic cylinder in all directions, eliminating possible blind spots and more effectively protecting the safety of workers when the telescopic cylinder is in operation and when replacing the rubber roller core and bearings.

[0015] As a preferred implementation of a three-column rubber roller mill, the distance between the sensor mounting brackets can be adjusted.

[0016] With the above structural design, the distance between the sensor mounting brackets can be adjusted, allowing the three-column rubber roller machine to flexibly adjust the spacing of the sensor mounting brackets according to different specifications of rubber rollers and actual working needs. This changes the monitoring range of the grating sensor, enhances the versatility and adaptability of the equipment, better meets diverse operating scenarios, and ensures the safety of workers under different working conditions.

[0017] As a preferred implementation of a three-column rubber roller machine, the bottom of each sensor holder is mounted on a fixed platform, and a slider is mounted on the bottom of each sensor holder. Two slide rails are mounted on the fixed platform, and the length direction of each slide rail is set along the arrangement direction of the two sensor holders. One slider is slidably mounted on one slide rail. The side of the slider at the bottom of each sensor holder away from the other sensor holder is connected to the telescopic shaft.

[0018] With the above structural design, each sensor holder is mounted on a slide rail of the mounting platform via a slider at its bottom. The slider is connected to a telescopic shaft, allowing the sensor holder to move smoothly along the slide rail and enabling precise adjustment of the distance between the sensor holders. Controlling the telescopic shaft allows for convenient and quick adjustment of the monitoring range according to actual conditions, improving the ease and efficiency of equipment adjustments and further enhancing the equipment's safety protection capabilities for workers in different working scenarios.

[0019] As a preferred implementation of a three-column rubber roller machine, the telescopic shaft is a cylinder telescopic shaft.

[0020] The above-mentioned structural scheme uses a cylinder telescopic shaft, which has the characteristics of fast response speed and stable power output. Using a cylinder telescopic shaft can quickly and accurately adjust the distance between the sensor mounting brackets, enabling the grating sensor to adapt to different working requirements in a timely manner. While ensuring that the equipment can quickly adjust the monitoring range, it also improves the overall operating efficiency and safety of the equipment.

[0021] As a preferred implementation of a three-column rubber roller mill, the telescopic shaft is a damped telescopic shaft.

[0022] By adopting the above structural design, the damped telescopic shaft provides a certain amount of resistance during the extension and retraction process, making the movement of the sensor mounting bracket smoother and slower, and facilitating cost-effective adjustment of the telescopic shaft's length. Simultaneously, the damping effect reduces vibration and impact during adjustment, extending the equipment's service life and further ensuring worker safety.

[0023] As a preferred implementation of a three-column rubber roller mill, the sensor mounting bracket includes a bottom bracket and a top bracket, with the grating sensor mounted on the top bracket, which is capable of rotating relative to the bottom bracket about a horizontal axis.

[0024] With the above structural design, the top support of the sensor holder can rotate relative to the bottom support around a horizontal pivot, allowing the angle of the grating sensor mounted on the top support to be adjusted, thereby changing the monitoring direction. By adjusting the angle of the grating sensor, it can better adapt to rubber rollers of different lengths and positions, as well as different working environments, expanding the monitoring range and overcoming the limitation of the monitoring range in existing technologies. This improves the adaptability and safety of the equipment in different working scenarios.

[0025] As a preferred implementation of a three-column rubber roller machine, the top support has a U-shaped structure, the grating sensor is installed on the outer wall of the side wing of the top support, the top of the bottom support extends into the top support, the top of the bottom support has a connection hole, the inner walls of the two side wings of the top support have opposite mounting holes, a horizontal rotating shaft is connected in the mounting hole, the horizontal rotating shaft passes through the connection hole, and the horizontal rotating shaft is dampedly connected to the connection hole.

[0026] The above structural design features a U-shaped top support with a damped connection between the horizontal pivot and the bottom support's connecting hole. The U-shaped structure facilitates the installation of the grating sensor and provides stable support, preventing interference between the sensor's rotation and the bottom support. The damped connection provides resistance during rotation, ensuring stability once the desired angle is reached. This prevents angle changes due to equipment vibration or other external forces, ensuring the grating sensor remains at the optimal monitoring angle, effectively improving monitoring performance and providing more reliable safety protection for personnel.

[0027] The beneficial effects of this utility model include:

[0028] This invention significantly expands the monitoring range of the telescopic cylinder's working area by installing grating sensors on both sides of the sensor mounting bracket, setting a specific number of detection heads, and using a reasonable size ratio. This improves detection sensitivity and accuracy, effectively preventing injury to workers during accidental equipment startup when replacing rubber sleeves, roller cores, and bearings. The adjustable spacing of the sensor mounting bracket, combined with a slider rail structure driven by the cylinder telescopic shaft or damped telescopic shaft, allows for flexible changes in the monitoring range according to roller specifications and operational needs, improving the convenience and efficiency of equipment adjustments. The sensor mounting bracket consists of a top support and a bottom support. The top support is rotatable and employs a U-shaped structure and damping connection design, enabling the grating sensor to adjust its monitoring angle to adapt to rollers of different lengths and positions, as well as different working environments. This comprehensively enhances the equipment's versatility, adaptability, and safety, providing reliable safety protection for workers and extending the equipment's service life.

[0034] 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 in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] Reference Figure 1-2This embodiment proposes a three-column rubber roller mounting machine, including two sensor mounting brackets 1, located on both sides of a rubber roller support 2. The rubber roller support 2 is supported by a telescopic cylinder 8, which passes through the rubber roller support 2. A grating sensor 3 is installed on both sides of each sensor mounting bracket 1. Each grating sensor 3 has several detection heads 4 distributed vertically. Two grating sensors 3 on the same side of the two sensor mounting brackets 1 form a group, with the detection heads 4 of the same group of grating sensors 3 facing each other and all facing the rubber roller support 2. The vertical dimension ratio of the grating sensor 3 to the rubber roller support 2 is greater than 1.3:1. The bottom of the grating sensor 3 is not higher than the top of the rubber roller support 2, and the top of the grating sensor 3 is not lower than the top of the telescopic cylinder 8, ensuring a large monitoring range and comprehensive coverage of areas with potential safety risks. In one specific embodiment, the vertical dimension of the grating sensor 3 is 200mm, and each grating sensor 3 has eight detection heads 4. By adjusting the descent frequency of the solenoid valve that is matched with the telescopic cylinder 8, the descent speed of the telescopic cylinder 8 is adjusted from the original 3 seconds / time to 5 seconds / time.

[0036] During operation, the detection head 4 emits and receives light, creating a monitoring light curtain over the rubber roller bracket 2 and its surrounding area. When a foreign object (such as a human body part or tool) enters the light curtain and blocks the light, the grating sensor 3 immediately detects the change in light. The grating sensor 3 is electrically connected to the control system. Once it detects a change in light, it determines that a foreign object has entered the danger zone and quickly transmits a signal to the control system. The control system then sends a command to the drive device of the telescopic cylinder 8 to immediately stop the operation of the telescopic cylinder 8, thereby preventing the telescopic cylinder 8 from causing injury to the workers while it is pressing down and ensuring operational safety.

[0037] The distance between the sensor mounting brackets 1 is adjustable. Each sensor mounting bracket 1 is mounted on a mounting platform 9 at its bottom, and each bracket has a slider 5 at its bottom. Two slide rails 6 are mounted on the mounting platform 9, with the length of each slide rail 6 aligned with the arrangement of the two sensor mounting brackets 1. One slider 5 is slidably mounted on one slide rail 6. The side of each sensor mounting bracket 1's slider 5 furthest from the other sensor mounting bracket 1 is connected to a telescopic shaft 7. The telescopic shaft 7 can be a cylinder telescopic shaft 7 or a damped telescopic shaft 7. When the telescopic shaft 7 moves, it moves the slider 5 along the slide rail 6, thereby changing the distance between the sensor mounting brackets 1 and adjusting the monitoring range of the grating sensor 3.

[0038] The sensor mounting bracket 1 includes a bottom bracket 11 and a top bracket 12. The grating sensor 3 is mounted on the top bracket 12, which is rotatable relative to the bottom bracket 11 via a horizontal pivot 13. The top bracket 12 has a U-shaped structure. The grating sensor 3 is mounted on the outer wall of the side wing of the top bracket 12. The top end of the bottom bracket 11 extends into the top bracket 12, and a connection hole is provided at the top end of the bottom bracket 11. Opposite mounting holes are opened on the inner walls of the two side wings of the top bracket. The horizontal pivot 13 is connected to the mounting holes and passes through the connection holes, forming a damped connection. When encountering rubber rollers of different lengths and positions, the operator can manually rotate the top bracket 12 to change the monitoring angle of the grating sensor 3. Because the connection hole between the horizontal pivot 13 and the bottom bracket 11 is damped, the top bracket 12 can stably maintain the angle after adjustment, ensuring that the grating sensor 3 can always effectively monitor the working area.

[0039] Work process:

[0040] Based on the specifications of the rubber roller to be processed, first adjust the distance between the sensor holders 1. Activate the control device for the telescopic shaft 7; the telescopic shaft 7 pushes the slider 5 at the bottom of the sensor holder 1, moving it smoothly along the slide rail 6 on the fixed platform 9 until the spacing of the sensor holders 1 matches the current rubber roller. Simultaneously, check the status of the grating sensor 3 to ensure it is operating normally.

[0041] When staff replace the rubber sleeve, rubber roller core, and bearing, the grating sensor 3 located on both sides of the rubber roller bracket 2, with its multiple detection heads 4, monitors the working area in all directions. Once a foreign object (such as a staff member's hand exceeding the safe range) enters the monitoring area, it immediately transmits a signal to the control system.

[0042] After confirming that the rubber roller core and bearing are correctly positioned and that no foreign objects have entered the danger zone, the telescopic cylinder 8 is activated. The telescopic cylinder 8 begins to press down and assemble, ensuring a tight fit between the rubber sleeve and the bearing. During the operation of the telescopic cylinder 8, the grating sensor 3 continuously monitors to ensure the safety of the working area. Its layout, with its bottom not higher than the top of the rubber roller support 2 and its top not lower than the top of the telescopic cylinder 8, ensures real-time monitoring of the entire critical area.

[0043] After the telescopic cylinder 8 completes one downward pressing and fitting action, it rises and resets. The operator removes the fitted rubber roller assembly and prepares to insert a new rubber sleeve, rubber roller core, and bearing, repeating the above loading and fitting process.

[0044] If different lengths and positions of rubber rollers are encountered during operation, the angle of the top bracket 12 of the sensor mounting bracket 1 can be adjusted. By manually rotating the top bracket 12, it rotates relative to the bottom bracket 11 with the horizontal rotating shaft 13 as the axis, changing the monitoring direction of the grating sensor 3 installed on the outer wall of the side wing of the top bracket 12. Since the connection hole between the horizontal rotating shaft 13 and the bottom bracket 11 is damped, after adjusting to a suitable angle, the top bracket 12 can stably maintain that angle, ensuring that the grating sensor 3 always monitors the working area at the optimal angle, thus ensuring operational safety.

[0045] 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.
