Description

Technical Field

[0001] The utility model belongs to the technical field of coilers, in particular to a detection device for the expansion and contraction of a coiler drum. Background Art

[0002] The expansion and contraction of the coiler drum is a crucial element in its operation. This expansion and contraction process accommodates coils of varying widths and diameters. The expansion and contraction of the drum securely grips coils of varying sizes, preventing them from loosening or slipping during the winding process. Furthermore, it ensures coiling quality. Precise expansion and contraction control ensures tight and neat winding, preventing wrinkles, deviations, and other quality issues.

[0003] During the production process of the leveling machine, several accidents occurred in which the reel could not be unloaded because the reel of the winder did not expand in diameter. The reason was that the system collected the electrical signal of the solenoid of the electromagnetic reversing valve of the expansion and contraction cylinder when the reel was expanding in diameter. If there was a problem with the solenoid valve or the hydraulic control circuit at this time, the reel would not expand in diameter, resulting in an accident that the reel could not be unloaded. It took a long time to rewind to the uncoiler, and the rewinding would appear in a tower shape and wrong edges. In severe cases, secondary accidents such as scraping and breaking of the belt would occur. A detection device for whether the reel has not expanded in diameter is needed to avoid such accidents. Utility Model Content

[0004] The purpose of the utility model is to provide a device for detecting the expansion and contraction of the winder drum. By providing a detection mechanism, the measuring plate and the detection ring cooperate with each other, and the diameter expansion of the drum can be detected according to the stroke of the detection ring, thereby avoiding the accident of being unable to unload the roll because the winder drum has not expanded in diameter, and solving the problem of being unable to detect the diameter expansion.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a detection device for the expansion and contraction of a reel of a winder, comprising a hydraulic cylinder and a hydraulic rod. The output end of the hydraulic cylinder is fixedly connected to the hydraulic rod. The hydraulic rod is provided with a detection mechanism and an expansion and contraction mechanism. The detection mechanism comprises a detection component, a buffer component and a fixing component.

[0007] The outer wall of the hydraulic cylinder is fixedly connected to a fixed sleeve, and a detection component is provided on the fixed sleeve. The detection component includes a plurality of grooves opened on the outer wall of the fixed sleeve. The outer wall of the fixed sleeve is fixedly connected to a plurality of measuring plates, and the outer walls of the plurality of measuring plates are provided with two detection rings.

[0008] Furthermore, the buffer assembly includes two connecting sleeves fixedly connected to the inner walls of the two detection rings, the inner walls of several of the connecting sleeves are slidably connected to sliding rods, and the ends of several of the sliding rods close to the hydraulic rod are fixedly connected to clamping blocks, and several of the clamping blocks are in contact with the outer wall of the hydraulic rod.

[0009] Furthermore, a spring is wound around the outer walls of the plurality of slide rods, one end of the spring is fixedly connected to the clamping block, and the other end of the spring is fixedly connected to the connecting sleeve.

[0010] Furthermore, the fixing assembly includes two bolts threadedly connected between the two detection rings, and the inner walls of the two detection rings are slidably connected to the outer wall of the measuring plate.

[0011] Furthermore, the expansion and contraction mechanism includes a limiting component and a connecting component. The limiting component includes a fixing frame fixedly connected to the left side of the fixing sleeve, and the groove slides through the fixing frame.

[0012] Furthermore, a plurality of sliding grooves are provided on the fixing frame, the inner walls of a plurality of the sliding grooves are slidably connected with sliders, and the left sides of a plurality of the sliders are fixedly connected with support plates.

[0014] The utility model has the following beneficial effects:

[0015] 1. By setting up a detection mechanism, the spring and the clamping block cooperate with each other to buffer the clamping force. When the detection ring applies pressure, the spring will compress and absorb part of the energy, thereby reducing the actual pressure applied to the hydraulic rod and protecting the hydraulic rod from overload damage. This design not only realizes the rapid installation of the detection ring, but also extends the service life of the hydraulic rod, ensuring the reliability and stability of the entire system. In addition, the measuring plate and the detection ring cooperate with each other to detect the diameter expansion of the reel according to the stroke of the detection ring, avoiding the accident of being unable to unload the reel due to the reel not expanding in diameter.

By setting up an expansion and contraction mechanism, the slide groove and the slider cooperate with each other, so that the slider can only slide on the inner wall of the slide groove, and the connecting plate and the hinged rod cooperate with each other. When the hydraulic cylinder drives the hydraulic rod to move left and right, multiple support plates can be moved closer or farther away from each other, so that the diameter of the reel can be expanded, ensuring that reels of different diameters can be fixed, which is convenient for winding.
