Description

Technical Field

[0001] This invention relates to the field of leveling device technology, specifically a leveling device based on belt conveyor processing. Background Technology

[0002] Belts used to cinch the waist, such as trouser belts, are commonly called leather belts. However, during the production of leather belts using existing belt processing machines, the high toughness of leather and the elasticity of the belts can easily cause damage to the belts themselves when subjected to the pressure of hard processing parts or excessive pressure during the leveling process. This damage to the surface of the belts can affect the quality of the finished product.

[0003] According to publicly available patent 202021838723.6, a leveling device based on belt conveyor processing includes a base and a heating device body. The heating device body is fixedly connected to one side of the upper surface of the base via four uprights. Third uprights are fixedly connected to both the front and rear ends of the upper surface of the base. Two of the third uprights have holes at their tops, and a first pressure roller is rotatably connected between the two third uprights. Spring connectors are elastically connected to the tops of the two third uprights, and fixing blocks are elastically connected to the tops of the two spring connectors. The two fixing blocks have holes in their middles and are rotatably connected to the first pressure roller. Second uprights are fixedly connected to both the front and rear ends of the other side of the upper surface of the base. Bearings are fixedly connected to the tops of the two second uprights, and a second pressure roller is rotatably connected between the two bearings. In the process of developing this invention, the inventors discovered that the existing technology has at least the following unresolved problems. By incorporating heating lamps, when the belt passes under the heating device, it is heated by the lamps, effectively heating the leather and softening it. This prevents significant damage to the softened belt even when subjected to external pressure during leveling. This solves the problem of damage to the leather surface during belt leveling. However, traditional belt leveling devices often experience excessive or insufficient leveling pressure after heating, leading to belt damage or incomplete leveling. Furthermore, the loading and unloading of these devices is cumbersome, and their manufacturing cost is high. Therefore, a new technical solution is needed to address these issues. Summary of the Invention

In addition, the leveling device is cumbersome to load and unload, and the leveling device is costly to manufacture.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a leveling device based on belt processing, comprising a leveling mechanism, the leveling mechanism including a mounting frame, the two ends of the mounting frame being respectively connected to a feeding conveyor belt and a discharging conveyor belt via two sets of rotating shafts, one of the two sets of rotating shafts being connected to a first pulley, the first pulley being connected to a second pulley via a transmission belt, the second pulley being connected to a mounting base via a drive motor, a plurality of first leveling rollers being installed between the feeding conveyor belt and the discharging conveyor belt, one end of the first leveling roller being connected to a chain via a gear, a plurality of second leveling rollers being installed directly above the plurality of first leveling rollers, the two ends of the second leveling rollers being connected to a support plate via a slider, the support plate having a plurality of grooves, the top end of the slider being connected to an electric push rod via a pressure sensor.

[0006] In a preferred embodiment of the present invention, a heating cover is installed above the feeding conveyor belt, a hot air blower is installed at the top of the heating cover, both ends of the heating cover are fixedly connected to the two sides of the mounting frame, the mounting end of the hot air blower is fixedly connected to the top of the heating cover, and the air outlet end of the hot air blower communicates with the interior of the heating cover.

[0007] In a preferred embodiment of the present invention, the two ends of the two sets of rotating shafts are rotatably connected to the inner sides of the two ends of the mounting bracket, one end of the two first pulleys is fixedly connected to one end of the two rotating shafts, one end of the transmission belt is sleeved inside the two first pulleys, and the other end of the transmission belt is sleeved inside the second pulley.

[0008] In a preferred embodiment of the present invention, the position of the second pulley corresponds to the position of the first pulley, the mounting end of the second pulley is fixedly connected to the output end of the drive motor, the mounting end of the drive motor is fixedly connected to the surface of the mounting base, and the top end of the mounting base is fixedly connected to one side of the bottom of the mounting frame.

[0009] In a preferred embodiment of the present invention, the two ends of the plurality of first leveling rollers are rotatably connected to the inner side of the mounting frame, one end of the plurality of gears is fixedly connected to one end of the plurality of first leveling rollers, and the chain meshes with the toothed end of the plurality of gears.

[0010] In a preferred embodiment of the present invention, the support plate is fixedly connected to both sides of the mounting frame, the size of the slider matches the size of the groove, and is slidably connected to its inner wall.

[0011] In a preferred embodiment of the present invention, the detection end of the pressure sensor is fixedly connected to the top of the slider, and the mounting end of the pressure sensor is fixedly connected to the output end of the electric actuator.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] This invention increases the pressure detection values ​​of multiple pressure sensors from the feed conveyor belt end to the discharge conveyor belt end in sequence. When the belt is leveled, the output end of the electric push rod drives the slider to slide inside the chute through the pressure sensor, so that the slider drives the second leveling roller to move downward. At this time, the second leveling roller moves downward to the appropriate position according to the pressure value on the belt, thereby adjusting the distance between the first leveling roller and the second leveling roller. This avoids the phenomenon that the leveling pressure is too high or too low during the leveling process after the belt is heated, which would cause damage to the belt or failure to level completely.

[0017] During the leveling process, the drive motor will drive the second pulley to rotate, and the second pulley will then drive the two sets of rotating shafts to rotate via the transmission belt. In this process, the two sets of rotating shafts will drive the feeding conveyor belt and the discharging conveyor belt to rotate respectively, thereby achieving automatic belt control and improving the convenience of belt feeding.

[0018] The rotating shaft drives other gears to rotate via gears and chains. These other gears then drive the first leveling roller to rotate, and the first leveling roller, in conjunction with the second leveling roller, rotates the belt. This allows the leveling device to use only one motor to drive its transmission components during operation, thereby reducing the manufacturing cost of the leveling device.

[0029] Example 1: A leveling device based on belt conveyor processing, see [link to example]. Figures 1 to 4The system includes a leveling mechanism, which comprises a mounting frame 1. Two sets of rotating shafts 11 connect the two ends of the mounting frame 1 to a feed conveyor belt 12 and a discharge conveyor belt 13, respectively. One of the rotating shafts 11 is connected to a first pulley 14. The first pulley 14 is connected to a second pulley 16 via a drive belt 15. The two ends of the two rotating shafts 11 are rotatably connected to the inner surfaces of both ends of the mounting frame 1. One end of each of the two first pulleys 14 is fixedly connected to one end of each of the two rotating shafts 11. One end of the drive belt 15 is fitted inside the two first pulleys 14, and the other end of the drive belt 15 is fitted inside the second pulley 16. The second pulley 16 is connected to a mounting base 18 via a drive motor 17. The position of the second pulley 16 is relative to the first... The position of the pulley 14 is corresponding, the mounting end of the second pulley 16 is fixedly connected to the output end of the drive motor 17, the mounting end of the drive motor 17 is fixedly connected to the surface of the mounting base 18, the top of the mounting base 18 is fixedly connected to one side of the bottom of the mounting frame 1, the upper surface of the first leveling roller 19 is flush with the surface of the feeding conveyor belt 12 and the discharging conveyor belt 13. When the belt is leveling, the drive motor 17 will drive the second pulley 16 to rotate, and then the second pulley 16 will drive the two sets of rotating shafts 11 to rotate through the transmission belt 15. During this process, the two sets of rotating shafts 11 will drive the feeding conveyor belt 12 and the discharging conveyor belt 13 to rotate respectively, thereby achieving automatic belt operation and improving the convenience of belt feeding.

[0030] Multiple first leveling rollers 19 are installed between the feeding conveyor belt 12 and the discharging conveyor belt 13. One end of the first leveling roller 19 is connected to a chain 21 via a gear 20. Both ends of the multiple first leveling rollers 19 are rotatably connected to the inner side of the mounting frame 1. One end of the multiple gears 20 is fixedly connected to one end of the multiple first leveling rollers 19. The chain 21 meshes with the toothed end of the multiple gears 20. The rotating shaft 11 drives the other gears 20 to rotate through the gears 20 and the chain 21. At this time, the other gears 20 will drive the first leveling rollers 19 to rotate. Then, the first leveling rollers 19 cooperate with the second leveling rollers 22 to rotate the belt. This allows the leveling device to use only one motor to drive its transmission components during use, thereby reducing the cost of manufacturing the leveling device.

[0031] Multiple second leveling rollers 22 are mounted directly above multiple first leveling rollers 19. The two ends of each second leveling roller 22 are connected to a support plate 24 via sliders 23. The support plate 24 has multiple grooves 25 and is fixedly connected to both sides of the mounting frame 1. The sliders 23 are sized to match the grooves 25 and are slidably connected to their inner walls. The top of each slider 23 is connected to an electric actuator 27 via a pressure sensor 26. The detection end of the pressure sensor 26 is fixedly connected to the top of the slider 23, and the mounting end of the pressure sensor 26 is fixedly connected to the output end of the electric actuator 27. The mounting end of the electric actuator 27 is fixedly connected to the top of the support plate 24 and corresponds to the position of the grooves 25. The two ends of each second leveling roller 22 are rotatably connected between two sliders 23 and are aligned with the positions of the first leveling rollers 19. Correspondingly, the pressure detection values ​​of multiple pressure sensors 26 increase sequentially from the feeding conveyor belt 12 end to the discharging conveyor belt 13 end. By increasing the pressure detection values ​​of multiple pressure sensors 26 sequentially from the feeding conveyor belt 12 end to the discharging conveyor belt 13 end, when the belt is leveled, the output end of the electric push rod 27 will drive the slider 23 to slide inside the slide groove 25 through the pressure sensor 26, so that the slider 23 drives the second leveling roller 22 to move downward. At this time, the second leveling roller 22 will move downward to the appropriate position according to the pressure value on the belt, thereby adjusting the distance between the first leveling roller 19 and the second leveling roller 22, so as to avoid the phenomenon that the leveling pressure is too high or too low during the leveling process after the belt is heated, which would cause the belt to be damaged or not leveled completely.

[0032] For details, see Figure 1 A heating cover 28 is installed above the feeding conveyor belt 12. A hot air blower 29 is installed on the top of the heating cover 28. The two ends of the heating cover 28 are fixedly connected to the two sides of the mounting frame 1. The mounting end of the hot air blower 29 is fixedly connected to the top of the heating cover 28. The air outlet of the hot air blower 29 is connected to the interior of the heating cover 28. Baffles 3 are installed between the multiple first leveling rollers 19 to prevent the belt from detaching from the first leveling rollers 19 during conveying.
