Description

Technical Field

[0001] The utility model relates to the field of transmission equipment, and particularly relates to a belt positioning and adjusting tensioning device. Background Art

[0002] In the field of machining production, it is very common to use a belt to transport products to be processed. For example, during assembly line production, semi-finished products completed in the previous process need to be transported to the next process for further processing. However, during the belt transmission process, as the running time extends, problems such as belt loosening or belt head deflection may occur, resulting in belt deviation, which seriously affects the service life of the belt. Therefore, to prevent the belt from becoming loose after long-term use, a tensioning and positioning adjustment device is needed to adjust the position of the belt in real time, so that the belt always maintains an appropriate tension and avoids belt deviation and slipping. Content of the Utility Model

[0003] The utility model provides a belt positioning and adjusting tensioning device, aiming to solve the problem that during the belt running process, the belt is prone to loosening or the belt head is deflected, resulting in belt deviation, which seriously affects the service life of the belt.

[0004] To achieve its purpose, the utility model adopts the following technical solutions:

[0005] A belt positioning and adjusting tensioning device includes a driving drum and a driven drum driven by a belt. A belt protection frame is arranged on the outer side of the belt. One side of the end of the driving drum is provided with a positioning frame. A plurality of pulleys are symmetrically arranged on both sides of the positioning frame. And a slide rail is arranged on the belt protection frame below the positioning frame. The pulleys can slide in the slide rail. After being supported by a driving drum bearing, the driving drum is fixed to the positioning frame through a driving drum bearing fixer. Two frame horizontal wheels are symmetrically arranged at the top of the positioning frame far from the belt. And two first fixed wheels collinear with the two frame horizontal wheels respectively are symmetrically arranged on the belt protection frame. Two second fixed wheels and two third fixed wheels are symmetrically arranged on the building above the belt protection frame. A steel wire rope is threaded through the two frame horizontal wheels. Both ends of the steel wire rope sequentially pass through the first fixed wheel, the second fixed wheel and the third fixed wheel on the same side and are connected to a counterweight.

[0006] Further, the positioning frame is rectangular.

[0007] Further, there are four pulleys, which are respectively arranged at the four corners of the positioning frame.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] The belt positioning, adjusting and tensioning device provided by the utility model fixes the driving roller on the positioning frame of the four-corner belt pulley, which is similar to a manned vehicle. The positioning frame is connected to the counterweight through a steel wire rope passing through the horizontal wheel of the frame. By adjusting the position of the positioning frame under the counterweight through the steel wire rope, the position of the driving roller is changed, so as to achieve the purpose of tensioning the belt, prevent the belt from running off track and extend the service life of the belt. The overall design is ingenious and highly practical. Brief Description of the Drawings

Detailed Embodiment

[0012] The following further describes the utility model with reference to the drawings:

[0013] As Figure 1 shown, the utility model is a belt positioning, adjusting and tensioning device, including a driving roller 3 driven by a belt 1 and a driven roller (since the driving roller and the driven roller driven by the belt are prior arts, the driven roller is not shown in Figure 1 ). To ensure the safety of transmission and prevent the belt 1 from shifting and slipping to cause injury, a belt protection frame 11 is provided on the outer side of the belt 1, and the belt protection frame 11 will not affect the normal transmission operation of the belt 1. On one side of the end of the driving roller 3, a rectangular positioning frame 6 is provided. Four pulleys 2 are symmetrically arranged at the four corners of the positioning frame 6, and a slide rail 7 is provided on the belt protection frame 11 below the positioning frame 6. The pulleys 2 can freely slide in the slide rail 7 to move the positioning frame 6; the driving roller 3 is fixedly connected to the positioning frame 6 through the driving roller bearing fixer 5 after being supported by the driving roller bearing 4, but does not affect the normal rotation of the driving roller 3; on the top of the side of the positioning frame 6 away from the belt 1, two horizontal wheels 8 of the frame are symmetrically provided, and two first fixed wheels 10 collinear with the two horizontal wheels 8 of the frame are symmetrically provided on the belt protection frame 11; on the roof of the building above the belt protection frame 11, two second fixed wheels 12 and two third fixed wheels 13 are symmetrically provided; a steel wire rope 9 first passes through the two horizontal wheels 8 of the frame, and then the two ends of the steel wire rope 9 pass out of the horizontal wheels 8 of the frame and respectively pass through the first fixed wheel 10, the second fixed wheel 12 and the third fixed wheel 13 on the same side in sequence and are all connected to the counterweight 14.

[0014] During operation, start the device, and drive the roller 3 to rotate to drive the belt 1 to operate. When the belt 1 is offset due to long-term operation, the positioning frame 6 is pulled by the steel wire rope 9 to move in the slide rail 7 driven by the pulley 2, driving the driving roller 3 to be adjusted back and forth, so as to timely adjust the position of the driving roller 3, thereby tightening the belt 1. Moreover, the configuration 14 can maintain the balance of the steel wire rope 9 for a long time under its own weight, ensuring that the frame horizontal wheels 8, the first fixed wheel 10, the second fixed wheel 12 and the third fixed wheel 13 on both sides are evenly stressed, ensuring that the driving roller 3 does not move randomly, the belt 1 operates normally, and the service life of the belt 1 is extended.
