[0025] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0026] Please refer to Figures 1 to 3 As shown, in the embodiment of the utility model,
[0027] A device for detecting the surface smoothness of a rubber roller comprises a support frame 1, a lateral driving mechanism 4, a roughness detector 5, a clamping and rotating mechanism and a height adjusting member.
[0028] Among them, a material rack plate 2 is fixedly installed on the top of the support frame 1, and two material rack plates 2 are provided. The two material rack plates 2 are equidistantly provided with a plurality of first positioning grooves for positioning and supporting the rubber roller. In this embodiment, the feeding mechanism 3 includes a second motor 301 and a base 302. The second motor 301 is fixedly installed on the support frame 1, and the base 302 is arranged between the two material rack plates 2. Feeding plates 303 are fixedly connected to both sides of the top of the base 302. Second positioning grooves for supporting the rubber roller are equidistantly provided on the feeding plate 303. A connecting plate 304 is fixedly connected to the bottom of the base 302. The opposite side ends of the connecting plate 304 are rotatably connected with rocking arms 307. The lower end of the rocking arm 307 is rotatably connected with a fixed seat 305 through a transmission shaft. The fixed seat 305 is fixed on the support frame 1, and one end of the transmission shaft is fixedly connected with a transmission gear 306. A synchronous gear is fixedly connected to the rotating shaft of the second motor 301, and the synchronous gear is transmission-connected to one of the transmission gears 306 through a first synchronous toothed belt 308.
[0029] By adopting the above technical solution, the rubber roller to be tested is placed between the two material racks 2, so that the shafts at both ends of the rubber roller are mounted in the first positioning grooves on the material racks 2. When the rubber roller needs to be transported, the second motor 301 is started, and the rocking arm 307 is driven to rotate through the synchronous gear and the transmission gear 306 in cooperation with the first synchronous toothed belt 308. As the rocking arm 307 moves upward, the feeding plate 303 lifts the rubber roller on the material rack 2 and moves it toward the direction close to the roughness detector 5, so that the rubber roller enters the next first positioning groove, and this cycle is repeated to achieve intermittent transportation of the rubber roller.
[0030] In this embodiment, the clamping and rotating mechanism includes a clamping component and a rotating component 6. The clamping component is provided with two groups, and the two groups of clamping components are symmetrically arranged on both sides of the support frame 1. The two groups of clamping components include a support plate 101, and a moving seat 102 is slidably provided on the top of the support plate 101. A second electric push rod 103 is fixedly installed on the top of the support plate 101, and the piston rod end of the second electric push rod 103 is fixedly connected to one side of the moving seat 102; the rotating component 6 includes a first motor 601 and a vertical plate 603. The first motor 601 is fixedly installed on one of the moving seats 102, and a first rubber pressure plate 602 is fixedly installed on the rotating shaft of the first motor 601. The vertical plate 603 is fixedly installed on the other moving seat 102, and a rotating rod 604 is rotatably installed on the upper part of the vertical plate 603 through a seat bearing, and the end of the rotating rod 604 is fixedly connected to a second rubber pressure plate 605.
[0031] By adopting the above design, when the rubber roller moves to the bottom of the roughness detector 5, the piston rod of the second electric push rod 103 is controlled to extend, so that the first rubber pressure plate 602 and the second rubber pressure plate 605 are pressed against the two ends of the rubber roller shaft to fix the rubber roller. When the smoothness of different positions of the rubber roller needs to be tested, the first motor 601 is controlled to rotate, so that the rubber roller can be driven to rotate, so that different positions of the rubber roller surface face the roughness detector 5.
[0032] In this embodiment, the transverse driving mechanism 4 includes a linear module 402, the tops of the two support plates 101 are fixedly connected to the vertical frames 401, the slide rails of the linear module 402 are fixedly installed between the two vertical frames 401, the height adjustment member is fixedly installed at the bottom of the slide table of the vertical frame 401, the height adjustment member includes a first electric push rod 7, the bottom of the piston rod of the first electric push rod 7 is fixedly installed with an assembly plate, and the roughness detector 5 is fixedly installed at the bottom of the assembly plate.
[0033] By adopting the above technical solution, when the rubber roller moves to the bottom of the roughness detector 5, the piston rod of the first electric push rod 7 is controlled to move toward the rubber roller. When the detection distance is reached, the roughness detector 5 is started to detect the smoothness of the rubber roller. Then, the roughness detector 5 is driven by the linear module 402 to move laterally to detect the smoothness of different positions of the rubber roller.
[0034] Specifically, in order to improve the stability of the feeding mechanism 3 when conveying the rubber roller, the two transmission gears 306 at both ends of the side of the connecting plate 304 away from the first synchronous toothed belt 308 are connected by a second synchronous toothed belt 309 .
[0035] Specifically, in order to realize automatic detection, a controller and a distance sensor 8 are also included. The distance sensor 8 is fixedly installed at the bottom of the assembly plate. The distance sensor 8 is electrically connected to the signal input terminal of the controller. The second motor 301, the first electric push rod 7, the second electric push rod 103, the first motor 601 and the roughness detector 5 are all controlled by the controller. The distance sensor 8 can be set to detect the distance between the roughness detector 5 and the rubber roller to avoid collision between the roughness detector 5 and the rubber roller.
[0036] In this embodiment, the distance sensor 8 and the controller model are not limited, as long as the rubber roller smoothness detection requirements are met. For example, the distance sensor 8 can use an ultrasonic distance sensor with a model of UM30-213113S07, the controller can use an ultra-miniaturized PLC controller of S7-200, and the roughness detector 5 can use a surface roughness tester with a model of TR200.
[0037] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.
[0038] Working principle: When in use, place the rubber roller to be tested between the two material racks 2, so that the shafts at both ends of the rubber roller are mounted in the first positioning grooves on the material racks 2, and then start the second motor 301 to transport the rubber roller to the bottom of the roughness detector 5, and then control the piston rod of the second electric push rod 103 to extend, so that the first rubber pressure plate 602 and the second rubber pressure plate 605 are against the two ends of the rubber roller shaft to fix the rubber roller, and control the piston rod of the first electric push rod 7 to move toward the rubber roller. When the detection distance is reached, start the roughness detector 5 to perform smoothness detection on the rubber roller. When it is necessary to detect the smoothness of different positions of the rubber roller, the roughness detector 5 is driven by the linear module 402 to move horizontally, and the smoothness of different positions of the rubber roller is detected. The first motor 601 can also be controlled to rotate the shaft, thereby driving the rubber roller to rotate, so that different positions of the rubber roller surface face the roughness detector 5, and thus 360° full-face detection of the rubber roller can be achieved.
