Abstract
Description
Technical fields:
[0001] This utility model belongs to the field of agricultural machinery belt production technology, and specifically relates to a device for measuring the thickness of the connecting layer of agricultural machinery belt. Background technology:
[0002] After the agricultural machinery belt is manufactured, the toothed sections are separated by an intermediate groove. The distance from the bottom of the intermediate groove to the lower surface of the belt is the thickness of the connecting layer. To ensure the quality of the agricultural machinery belt, the thickness of the connecting layer needs to be measured. Measurement is generally done using calipers or a projection method, but both methods have drawbacks. When using calipers, the narrow, arc-shaped bottom of the intermediate groove makes measurement inconvenient. When using the projection method, the presence of fibers extending from the belt body within the intermediate groove affects the measurement accuracy.
[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content:
[0004] The purpose of this invention is to provide a device for measuring the thickness of the connecting layer of agricultural machinery belts, thereby overcoming the defects in the prior art.
[0005] To achieve the above objectives, this utility model provides a device for measuring the thickness of the connecting layer of an agricultural machinery belt, including a base, a transmission mechanism, a track switching mechanism, a measuring mechanism, a belt length adjustment mechanism, and a tensioning mechanism. The base is equipped with the transmission mechanism, track switching mechanism, and belt length adjustment mechanism. An agricultural machinery belt is mounted on the transmission mechanism. The track switching mechanism is equipped with the measuring mechanism, which is movable along the width direction of the agricultural machinery belt. The belt length adjustment mechanism is equipped with the tensioning mechanism, which is movable along the length direction of the agricultural machinery belt. The transmission mechanism… The system includes a drive pulley and a tension pulley. The agricultural machinery belt is fitted between the drive pulley and the tension pulley, and a tensioning mechanism is connected to the tension pulley. The measuring mechanism includes a digital dial indicator with a ball-head probe at its front end. The digital dial indicator is vertically mounted on the measuring mechanism, with the ball-head probe positioned above the agricultural machinery belt. Based on the length of the agricultural machinery belt, a belt length adjustment mechanism adjusts the length between the tension pulley and the drive pulley. The tensioning mechanism adjusts the position of the tension pulley along the length of the agricultural machinery belt. The digital dial indicator measures the thickness of the connecting layer. A track switching mechanism adjusts the position of the digital dial indicator along the width of the agricultural machinery belt, switching the measurement track.
[0006] Preferably, in the technical solution, the track switching mechanism includes a bracket, a first servo motor, a first ball screw, a first linear guide rail, a first connecting plate, and a first linear slider. The bracket is mounted on a base, and the first servo motor and the first linear guide rail are mounted on the bracket.

When the lifting cylinder drives the toothed pressure plate to rise, the toothed pressure plate drives the digital dial indicator to rise as a whole through the fixing ring. Conversely, when the toothed pressure plate descends and engages with the toothed structure of the agricultural machinery belt, the digital dial indicator, which loses its support, descends until the ball-head thin rod probe contacts the bottom of the middle groove.

[0020] The measuring mechanism 4 includes a digital dial indicator 40, a frame 41, a toothed pressure plate 42, a lifting cylinder 43, a guide sleeve 44, a guide rod 45, and a fixing ring 46.

The frame 41 has a "C" shaped structure, and the agricultural machinery belt 7 is located in the inner cavity of the frame 41. The upper end of the frame 41 is equipped with the digital dial indicator 40, the lifting cylinder 43, and the guide sleeve 44. The measuring rod 47 at the lower end of the digital dial indicator 40 passes through the toothed pressure plate 42. The measuring rod 47 has a ball-headed thin rod probe 48 at its end, and a guide rod 45 is housed in a guide sleeve 44. The guide rod 45 and the guide sleeve 44 form a guiding mechanism.

The ball-headed thin rod probe 48 is aligned with the middle groove 70 of the agricultural machinery belt. The bottom surface of the inner cavity of the frame 41 serves as the measurement reference plane, which contacts the lower surface of the agricultural machinery belt 7. A fixing ring 46 is provided on the measuring rod 47. The digital dial indicator 40 is connected to an external server via a data cable 49 to record measurement data.
[0021] The belt length adjustment mechanism 5 includes a second servo motor 50, a second ball screw 51, a second linear guide rail 52, a second linear slider 53, a slide plate 54, and a second connecting plate 55.

[0023] During operation, the piston rod of the lifting cylinder 43 descends, and the toothed pressure plate 42 descends through the guide sleeve 44 and the guide rod 45. The digital dial indicator 40 loses its support and descends simultaneously until the ball-head thin rod probe 48 contacts the measurement reference plane. At this time, the digital dial indicator is set to zero.
[0024] When the piston rod of the lifting cylinder 43 rises, it drives the toothed pressure plate 42 to rise.

The tensioning cylinder 61 pulls the tension wheel 21 to tension the agricultural machinery belt 7. The lifting cylinder 43 drives the toothed pressure plate 42 to flatten and position the agricultural machinery belt 7 to be tested. At the same time, the ball-head thin rod probe 48 contacts the bottom of the middle groove 70 of the agricultural machinery belt 7 to be tested. At this time, the reading of the digital display dial indicator 40 is the dimension A - the distance from the bottom of the groove to the lower plane, that is, the thickness of the connecting layer, which can be sent to the external server for recording via the data cable 49.
[0025] The toothed pressure plate 42 rises and resets, the drive wheel 20 rotates, and the agricultural machinery belt 7 under test rotates to the next measurement point of the intermediate groove 70 for measurement. This continues until all measurement points of the intermediate groove 70 are completed. Then, the first servo motor 31 drives the first ball screw 32, which moves the frame 41 along the first linear guide rail 33 via the first connecting plate 34 to the next intermediate groove 70 for measurement. This process continues until all intermediate grooves 70 of the agricultural machinery belt 7 have been measured.
