[0003] However, in the existing motor belt tightening operation process, since the belt is installed as a whole and fixed as a whole, when adjusting the belt later, it needs to be disassembled, replaced and adjusted again, which is relatively cumbersome. It makes tension adjustment difficult and lacks a convenient fine-tuning mechanism. Therefore, it is necessary to propose a new type of motor belt tightening tooling. Utility Model Content

A motor belt tightening tool is proposed.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a motor belt fastening tool, comprising a sheet metal frame, the sheet metal frame is composed of sheet metal plates on both sides and four connecting fastening bolts, and the surfaces of the sheet metal plates in the sheet metal frame are provided with adjusting distance slide grooves, and the edge connection block is fastened with the yield installation space formed by the sheet metal frame, and a fine-tuning slide rail is installed at the bottom of the edge connection block, and the fine-tuning slide rail is composed of a slide groove and a fine-tuning control motor. The inner sliding connection of the fine-tuning slide rail is connected to the edge connection sliding block plate, and the bottom wall surface of the edge connection sliding block plate is provided with a groove along the sliding side rail, and the groove is fastened to the mounting plate on the back surface of the sliding side rail, and the side frame of the mounting plate is provided with a driving motor, and the output end of the driving motor is connected with a rotating gear.
[0006] Preferably, the side end of the rotating tooth is meshedly connected with a rack, and the side end of the rack is fastened with an edge-jointed slide.
[0007] Preferably, a plurality of auxiliary rollers are mounted on the inner surface of the edge-jointed slide, and a belt fitting arc limiting slider is fastened to the side end surface of the top wall of the edge-jointed slide.

The belt fitting arc limiting slider ensures that the side of the belt is effectively in the operation offset area during this process to prevent the belt from running off and slipping. The overall belt can be effectively fine-tuned during operation without the need for re-disassembly, replacement and adjustment.
[0014] 2. In the utility model, during use, the brushless control motor is started to drive the short adjustment screw at the bottom to rotate, thereby controlling the sliding connection to slide longitudinally along the adjustment distance slide groove, so as to facilitate the adjustment of the relative position between the belt fitting limiting wheel and the auxiliary roller, and provide adaptive adjustment for motor belts of different specifications. The height difference design between the belt fitting limiting wheel and the multiple sets of auxiliary rollers helps to first apply preliminary positioning and guidance to the belt through the belt fitting limiting wheel during the tightening process, and then the auxiliary rollers follow closely to evenly distribute the pressure to ensure that the belt is flat and wrinkle-free and tightened in place.

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.
[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0022] Example 1, as Figure 1 - Figure 4 As shown, the utility model provides a technical solution: a motor belt fastening tool, including a sheet metal frame 1, the sheet metal frame 1 is composed of sheet metal sheets on both sides and four connecting fastening bolts, the surface of the sheet metal sheets in the sheet metal frame 1 is provided with an adjustment distance slide groove 2, the side block is fastened to the yield installation space formed by the sheet metal frame 1, the bottom of the side block is installed with a fine-tuning slide rail 9, the fine-tuning slide rail 9 is composed of a slide groove and a fine-tuning control motor, the interior of the fine-tuning slide rail 9 is slidably connected to the side sliding block plate 10, the side sliding block The bottom wall surface of the plate 10 is provided with a grooved sliding rail 11, and the back surface of the grooved sliding rail 11 is fastened with a mounting plate 16. A driving motor 17 is mounted on the side of the mounting plate 16, and the output end of the driving motor 17 is connected to a rotating gear 18. The side end of the rotating gear 18 is meshed with a rack 15, and the side end of the rack 15 is fastened with an edge-connected skateboard 12. A plurality of sets of auxiliary rollers 13 are mounted on the inside of the surface of the edge-connected skateboard 12, and the side end surface of the top wall of the edge-connected skateboard 12 is fastened with a belt fitting arc limiting slider 14.
[0023] The belt is then placed between the auxiliary roller 13 and the belt fitting limiting wheel 3 to pass through, and the position of the belt edge is initially positioned by the fine-tuning slide rail 9 at the bottom of the edge block. At this time, the fine-tuning control motor has not yet been started, and the slide groove allows slight longitudinal position adjustment to facilitate the contact between the belt fitting arc limiting slider 14 and the belt edge. Then the operator activates the fine-tuning control motor through the external PLC controller, so that the fine-tuning control motor drives the slide to move finely in the slide groove, so that the belt fitting arc limiting slider 14 forms a precise fit and calibration with the belt edge, and the precise control capability of the fine-tuning slide rail 9 ensures the high accuracy of the installation position and reduces the installation error. Then the drive motor 17 on the mounting plate 16 is started, and the rotating gear 18 at its output end begins to rotate. As the rotating gear 18 rotates, it engages with the rack 15, driving the rack 15 to slide horizontally up and down along the side surface of the edge sliding block plate 10. This action is transmitted to the The edge-jointed slide 12 realizes vertical displacement of the edge-jointed slide 12 inside the groove-along sliding rail 11, and then the translation of the edge-jointed slide 12 drives multiple sets of auxiliary rollers 13 to rise and fall along the groove-along sliding rail 11, so that multiple sets of auxiliary rollers 13 are located on the lower surface of the belt for contact and rolling. The rolling and lifting of the auxiliary rollers 13 will gradually adjust the tension of the belt in cooperation with the belt fitting limiting wheel 3 until a predetermined tension value is reached. The belt fitting arc limiting slider 14 ensures that the edge of the belt is effectively in the operating offset area during this process to prevent the belt from running off track and slipping. After the belt reaches the ideal tension, the driving motor 17 is stopped, and the position of the edge-jointed slide 12 can be locked by an external fixing device (limit block, self-locking structure, etc.) to prevent loosening due to vibration and other reasons. At this point, the fastening installation of the belt is completed, ensuring the high efficiency and stability of the motor transmission (and the adjustment of the above-mentioned overall structure can be feedback-adjusted according to the tension detection sensor installed in the motor or on the surface of the conveyor belt).
[0024] Example 2, as Figure 1 - Figure 4 As shown, two groups of sliding guide columns 4 are symmetrically installed on the left and right sides of the sheet metal frame 1, and a brushless control motor 5 is installed on the top wall surface of the convex edge of the side end of the sheet metal frame 1. The bottom output end of the brushless control motor 5 is connected to a short adjusting screw 6, and the external thread of the short adjusting screw 6 is connected to a sliding connector 8. The side of the sliding connector 8 is connected to a belt fitting limiting wheel 3, and the sliding connector 8 drives the belt fitting limiting wheel 3 to slide inside the distance adjustment slide 2 for adjustment. There is a height difference in the position setting of the belt fitting limiting wheel 3 and multiple groups of auxiliary rollers 13. The side of the sheet metal frame 1 is fastened with an arc edge frame 7. The arc edge frame 7 is used to be installed on the side of the frame of the belt conveyor structure according to needs, so that the belt can be restricted and fastened as a whole.
[0025] In this embodiment, the sheet metal frame 1 is placed at an appropriate position of the belt conveyor structure, and is firmly connected to the side of the conveyor belt frame by installing the arc edge frame 7. The purpose of installing the arc edge frame 7 is to ensure that the entire tooling has a good support and guiding effect on the fitting and tightening of the belt. By starting the brushless control motor 5, the short adjustment screw 6 at the bottom is driven to rotate, and then the sliding connection 8 is controlled to slide longitudinally along the adjustment distance slide 2, so as to facilitate the adjustment of the relative position between the belt fitting limiting wheel 3 and the auxiliary roller 13, and provide adaptive adjustment for motor belts of different specifications. The height difference design between the belt fitting limiting wheel 3 and the multiple sets of auxiliary rollers 13 helps to first apply preliminary positioning and guidance to the belt through the belt fitting limiting wheel 3 during the tightening process, and then the auxiliary roller 13 follows closely to evenly distribute pressure to ensure that the belt is flat and wrinkle-free and tightened in place.
[0026] The working principle of this embodiment is as follows: the sheet metal frame 1 is placed at an appropriate position of the belt conveyor structure, and is firmly connected to the side of the conveyor frame by installing the arc edge frame 7. The function of installing the arc edge frame 7 is to ensure that the entire tooling has a good support and guiding effect on the fitting and tightening of the belt, so that during use, the belt is placed between the auxiliary roller 13 and the belt fitting limiting wheel 3 to pass through, and the position of the belt side is preliminarily positioned through the fine-tuning slide rail 9 at the bottom of the edge block. At this time, the fine-tuning control motor has not yet started, and the slide groove allows a slight longitudinal position adjustment to facilitate the contact between the belt fitting arc limiting slider 14 and the belt side. Then the operator activates the fine-tuning control motor through the external PLC controller so that the fine-tuning control motor The driving slide moves finely in the slide groove, so that the belt fitting arc limiting slider 14 is accurately fitted and calibrated with the side of the belt, and the precise control ability of the fine-tuning slide rail 9 ensures the high accuracy of the installation position and reduces the installation error. Then the driving motor 17 on the mounting plate 16 is started, and the rotating gear 18 at its output end begins to rotate. As the rotating gear 18 rotates, it engages with the rack 15, driving the rack 15 to slide horizontally up and down along the side surface of the edge sliding block plate 10. This action is transmitted to the edge sliding plate 12 through the connection between the rack 15 and the edge sliding plate 12, so that the edge sliding plate 12 is located inside the groove along the sliding rail 11 to form a vertical displacement, and then the translation of the edge sliding plate 12 drives multiple sets of auxiliary rollers 13 along The grooves are lifted and lowered along the sliding rails 11, so that multiple sets of auxiliary rollers 13 are located on the lower surface of the belt for contact and rolling. The rolling and lifting of the auxiliary rollers 13 will gradually adjust the tension of the belt in cooperation with the belt fitting limiting wheel 3 until the predetermined tension value is reached. The belt fitting arc limiting slider 14 ensures that the side of the belt is effectively in the operating offset area during this process to prevent the belt from running off and slipping. After the belt reaches the ideal tension, the driving motor 17 is stopped, and the position of the edge sliding plate 12 can be locked by an external fixing device (limiting block, self-locking structure, etc.) to prevent loosening due to vibration and other reasons. At this point, the fastening installation of the belt is completed, ensuring the high efficiency and stability of the motor transmission (and can be installed according to the The tension detection sensor in the motor or on the surface of the conveyor belt is used to perform feedback adjustment on the adjustment of the above-mentioned overall structure), wherein the brushless control motor 5 can be started to drive the short adjustment screw 6 at the bottom to rotate, and then control the sliding connection 8 to slide longitudinally along the adjustment distance slide 2, so as to facilitate the adjustment of the relative position between the belt fitting limiting wheel 3 and the auxiliary roller 13, and provide adaptive adjustment for motor belts of different specifications. The height difference design between the belt fitting limiting wheel 3 and the multiple sets of auxiliary rollers 13 helps to first apply preliminary positioning and guidance to the belt through the belt fitting limiting wheel 3 during the tightening process, and then the auxiliary roller 13 follows closely to evenly distribute the pressure to ensure that the belt is flat and wrinkle-free and tightened in place.
