Description

Technical Field

[0001] This utility model relates to the field of belt adjustment technology, specifically to a positioning belt lifting and adjusting device. Background Technology

[0002] In fields such as material handling and automated production, positioning belts are core components for material transmission and positioning, and their operational stability directly affects production efficiency and product quality. To adapt to the material height and tension adjustment requirements under different working conditions, positioning belt lifting and adjusting devices have become key supporting equipment.

[0003] When the positioning belt is in operation, the sliding parts of traditional adjustment devices are prone to radial displacement due to vibration, causing the adjustment trajectory to deviate from the preset direction, resulting in problems such as belt misalignment and abnormal noise. At the same time, the lack of a coordination mechanism between manual and automatic adjustment, and the fact that automatic adjustment modules often use rigid drive structures, make them prone to generating impact loads when responding to tension fluctuations, which aggravates the wear of the belt and rotating rollers and shortens the service life of the equipment.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0021] In the description of this utility model, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating the connection relationship between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0022] The positioning belt lifting and adjusting device provided in this embodiment, such as Figures 1-4 As shown, it includes: a fixed frame 100, a positioning belt 200 rotatably connected to the fixed frame 100, a rotating roller rotatably connected to the fixed frame 100 and in contact with the inner side of the positioning belt 200, a drive motor connected to the rotating roller installed on one side of the fixed frame 100, and a telescopic leg 300 installed at the bottom of the fixed frame 100; an adjustment mechanism 400, disposed on the fixed frame 100, the adjustment mechanism 400 including a slide groove 410 formed on the surface of the fixed frame 100, a slider 430 slidably connected in the slide groove 410, a rotating roller rotatably connected to one side of the slider 430, a positioning rod 420 fixedly connected in the slide groove 410 and slidably connected to the slider 430, a sliding seat 440 installed on the surface of the positioning rod 420, an adjustment ring 460 threadedly connected to the surface of the sliding seat 440, and the slider 430 disposed at one end of the adjustment ring 460.

[0023] The positioning belt lifting adjustment device using the above technical solution uses an electromagnet 480 that controls the magnitude of the magnetic force through a current signal, indirectly driving the sliding seat 440 to slide along the positioning rod 420. Real-time fine adjustment during equipment operation can automatically compensate for tension deviations caused by material load fluctuations, belt thermal expansion and contraction, or long-term wear. The adjustment ring 460 has anti-slip textures added to its outer circumference and is equipped with a hand-held turntable, increasing the operating contact area while preventing slippage. This allows the operator to easily apply adjustment force during equipment operation, reducing the labor intensity of manual intervention. The threaded transmission structure, combined with the guiding constraint of the positioning rod 420, improves the adjustment accuracy.

[0024] To achieve automatic adjustment of power output and precise locking, an electromagnet 480 is fixedly connected within the sliding groove 410. The electromagnet 480 has a through hole corresponding to the positioning rod 420, and the sliding seat 440 is configured as a magnetic seat. When the electromagnet 480 is energized, the sliding seat 440 can be magnetically attracted to fix its position. When the power is off, the sliding seat 440 is released to meet adjustment requirements. The direction of the magnetic force can also be changed to push the sliding seat 440 away, facilitating dynamic adjustment.

[0025] To enhance the motion stability of the sliding seat 440 and achieve adjustment buffering, a limiting hole corresponding to the positioning rod 420 is also provided on the sliding seat 440. The sliding seat 440 is slidably connected to the positioning rod 420. A spring 470 is sleeved on the surface of the positioning rod 420 between the adjusting ring 460 and the slider 430. The spring 470 can absorb the impact force when the adjusting ring 460 pushes the slider 430, preventing damage to the components caused by rigid contact, and at the same time providing reset assistance during reverse adjustment.

[0026] To improve the ease of manual adjustment and reduce effort, the adjusting ring 460 has evenly distributed anti-slip textures on its outer circumference, and a hand-held turntable with a diameter larger than that of the adjusting ring 460 is fixedly connected to the end of the adjusting ring 460 away from the slider 430. By increasing the lever arm, the force required for manual adjustment is reduced, allowing the operator to easily perform fine adjustments during equipment operation and reducing labor intensity.

[0027] To achieve real-time monitoring and closed-loop control of belt tension, the electromagnet 480 is electrically connected to a controller. A tension sensor for detecting and positioning the belt tension 200 is installed on the mounting bracket 100, and the tension sensor is connected to the controller via a signal connection. When the tension sensor detects that the belt tension deviates from the preset range, it can feed the signal back to the controller in real time. The controller changes the magnetic force output by adjusting the current of the electromagnet 480, thereby driving the sliding seat 440 to adjust the belt tension, ensuring that the belt is always in a stable operating state.

[0028] To optimize the buffering effect and adapt to different load requirements, spring 470 is designed as a disc spring, with its two ends abutting against adjusting ring 460 and slider 430, respectively. The preload of spring 470 can be changed by rotating adjusting ring 460, thereby adapting to the tension buffering requirements under different material loads and preventing belt damage due to sudden tension changes.

[0029] For height self-adjustment and stable support of the device, the telescopic leg 300 includes an outer tube and an inner rod. The surface of the outer tube has scale lines distributed along its length. The inner rod is fixedly connected to the outer tube by locking bolts, the end of which penetrates the outer tube and abuts against the surface of the inner rod. By tightening the bolts, the inner rod and outer tube can be rigidly fixed, preventing loosening during support and ensuring the overall stability of the device when conveying heavy materials.

[0030] In summary, the positioning belt lifting and adjusting device provided in this embodiment has the following advantages: the electromagnet 480 controls the magnitude of the magnetic force through a current signal, indirectly driving the sliding seat 440 to slide along the positioning rod 420. Real-time fine adjustment during equipment operation can automatically compensate for tension deviations caused by material load fluctuations, belt thermal expansion and contraction, or long-term wear. The adjusting ring 460 is equipped with anti-slip textures on its outer circumference and a hand-held turntable, increasing the operating contact area while preventing slippage. This allows the operator to easily apply adjustment force during equipment operation, reducing the labor intensity of manual intervention. The threaded transmission structure, combined with the guiding constraint of the positioning rod 420, improves the adjustment precision.

[0031] The controllers available can be Honeywell models such as: 1 / 16 DIN controllers (e.g., UDC1200); 1 / 32 DIN controllers (e.g., UDC700); 1 / 4 DIN controllers (e.g., UDC2500, UDC3200, UDC3500); 1 / 8 DIN controllers (e.g., UDC1700); EasySet digital controllers (e.g., EDC201, EDC202, EDC203); DC1000 controller; DCP250 programmer; DCP50DIN programmer, etc. Among them, the tension sensor can be selected from the ALTECLX series: LX-150N, LX-300N, LX-500N, LX-1000N, which, together with the TC808, TC950 tension controller, etc., form a tension control system to realize closed-loop tension control. It is widely used in control systems of gravure printing machines, slitting machines, etc., and is especially suitable for vertical installation.

[0032] In use, first adjust the overall height of the fixing bracket 100 by connecting the outer tube of the telescopic leg 300 to the inner rod, and then secure it with locking bolts. After the drive motor starts, the positioning belt 200 runs with the rotating roller. At this time, the tension sensor monitors the belt tension in real time and feeds it back to the controller. When the belt tension is abnormal, the controller adjusts the current of the electromagnet 480, which drives the sliding seat 440 to move the adjusting ring 460 through magnetic force. With the buffering effect of the disc spring 470, the slider 430 is pushed to adjust the position of the rotating roller, thus achieving automatic tension compensation. If manual intervention is required, the operator can rotate the adjusting ring 460 by hand-held turntable and use the thread transmission of the external thread 450 to precisely adjust the position of the slider 430. During the adjustment process, the electromagnet 480 maintains the basic magnetic force to ensure the stability of the sliding seat 440, thereby achieving coordinated operation of manual and automatic adjustment.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
