Feed amount detector

Abstract

The invention discloses a feed amount detector. The feed amount detector comprises a measuring tool frame placed between a bottom cutter and a round cutter, a gear and a rack meshed with the gear are arranged in the measuring tool frame, the lower portion of the measuring tool frame is provided with a groove hole and a compression rod installed in the groove hole in a matched mode, a spring is arranged between the compression rod and the innermost end of the groove hole, teeth meshed with the gear are arranged on the compression rod, a dial indicator is fixedly arranged on the measuring tool frame and provided with a measuring rod which fixedly makes contact with the rack and is capable of moving back and forth relative to the dial indicator, the dial indicator is arranged at one end of the measuring tool frame, the bottom face at the other end of the measuring tool frame is an arc surface, the top face at the other end of the measuring tool frame is a plane, the radius of the arc surface is consistent with the radius of the bottom cutter, the arc surface coincides with the arc of the bottom cutter face, and the plane is placed on a shaft of the round cutter. When paper is cut, the feed amount of the cutters can be accurately adjusted through the feed amount detector, so that the cutters are in the optimal use state, the product quality is ensured, and the service life of the cutters is prolonged.

Description

technical field [0001] The present invention relates to the technical field of detection of feed amount in the mechanical field of slitting industry (including slitting paper, film, cloth, leather, etc.), especially relates to a device that can accurately adjust the feed amount of a knife when cutting paper. Feed amount detector. Background technique [0002] At present, it is used to detect the feed rate and adjust the feed rate of the slitting machine tool through human experience and visual inspection. There is also a vernier caliper stuck at the shaft head of the bed knife and the round knife for detection, which is obtained by calculating the theoretical distance. The distance between the shaft heads of the cutters of each size; however, the position of the knife on the slitting machine is very narrow, the vernier caliper is not easy to level, and the shaft head of the bed knife is painted with paint, and the paint of some bed knives is worn or lost. However, the theore...

[0002] At present, it is used to detect the feed rate and adjust the feed rate of the slitting machine tool through human experience and visual inspection. There is also a vernier caliper stuck at the shaft head of the bed knife and the round knife for detection, which is obtained by calculating the theoretical distance. The distance between the shaft heads of the cutters of each size; however, the position of the knife on the slitting machine is very narrow, the vernier caliper is not easy to level, and the shaft head of the bed knife is painted with paint, and the paint of some bed knives is worn or lost. However, the theoretical distance is passed. The diameter of the shaft head without painting is calculated, which often makes the adjustment of the cutting amount of the tool inaccurate, affects the product quality and the tool is fragile or the life is not long
