Description

Technical Field

[0001] The utility model relates to the technical field of coiling machines, and particularly relates to a drum structure of a coiling machine. Background Art

[0002] A coiling machine is a device used to unwind or feed coiled materials, and is widely used in various industrial production fields, such as processing, packaging, transportation and other links in industries such as metal products, plastic products, and paper products. According to different functions and structures, coiling machines can be divided into various types, such as automatic coiling machines, coiling feeders, and coiling turning machines.

[0003] After retrieval, Chinese Patent Publication No. CN220901460U discloses a mandrel structure of an uncoiler, which includes a main shaft. A first limiting plate is fixedly connected to the left end of the main shaft. A rubber pad is fixedly connected to the outer side of the first limiting plate. There are inclined surfaces on the surface of the main shaft. An expanding diameter plate is slidably arranged on the outer side of the inclined surface. The left and right ends of the expanding diameter plate are slidably provided with drum covers, and the inner end surfaces of the expanding diameter plate and the drum covers are in contact; the outer side surface of the left drum cover is in contact with the inner end surface of the first limiting plate; each drum cover is detachably connected with a buckle cover; the inner side surface of the buckle cover is flush with the inner side surface of the drum cover; it also includes a plurality of rollers rotatably arranged inside the expanding diameter plate. The outer circumference of the roller is directly or indirectly pressed against the inclined surface, and the roller is in contact with the upper end surface inside the expanding diameter plate; a notch is formed on the right side of the expanding diameter plate, and a positioning pin is embedded in the notch. The positioning pin passes through the inclined surface and is threadedly connected to the main shaft. A plurality of rollers are arranged inside the expanding diameter plate, so that the service life of the expanding diameter plate is longer.

[0004] However, in the above technical solution, only the inclined surfaces on the main shaft are used to contact the rollers to increase the diameter of the expanding diameter plate. However, the adjustment of the diameter of the expanding diameter plate depends on the length of the main shaft and the angle of its inclined surface. When the diameter to be adjusted is relatively large or small, the main shaft needs to be moved over a large range. Since the angle of the inclined surface on the main shaft is fixed, the main shaft always needs to be moved over a long range. Summary of the Utility Model

Compared with the first embodiment, the detailed structure of the expansion component is described in this embodiment. The expansion component includes a telescopic device 3, a support plate 4, a diameter-increasing plate 5, and a roller 6. The telescopic end of the telescopic device 3 passes through the cylinder cover 2 and is connected to one end of the main shaft 1; the telescopic device 3 is selected but not limited to a hydraulic cylinder; the telescopic device 3 is connected to the coiler.

[0025] The rollers 6 are evenly distributed at equal intervals along the length direction of the arc plate 7, and the rollers 6 are rotatably connected to the fixing plates 8 by bearings.

[0026] Embodiment Three

[0027] As Figures 2-3 shown in the figure, a drum structure of a coiler proposed by the present utility model. Compared with the second embodiment, the detailed structure of the connection component is described in this embodiment. The connection component includes two T-shaped blocks 11, an adjusting rod 13, a rotating block 14, a moving rod 15, and an elastic member 16. The two T-shaped blocks 11 are arranged in parallel and are connected to the main shaft 1. The T-shaped blocks 11 are slidably connected to T-shaped grooves 12 opened on the support plates 4; the adjusting rod 13 is rotatably connected to a receiving groove opened at one end of the main shaft 1 away from the cylinder cover 2 by a bearing.

[0028] Embodiment Four

[0029] As Figures 2-4As shown, a drum structure of a coiling machine proposed by the present utility model. Compared with the third embodiment, the detailed structure of the limiting component is described in this embodiment. The limiting component includes a moving ring 17, an adjusting screw 18, a handle 19, and a guide rod 20. The moving ring 17 is arranged parallel to the cylinder cover 2. The moving ring 17 is sleeved outside the main shaft 1. One end of the adjusting screw 18 is rotatably connected to the moving ring 17, and the other end of the adjusting screw 18 passes through the threaded hole on the cylinder cover 2 to connect the handle 19. The guide rod 20 is arranged parallel to the adjusting screw 18. One end of the guide rod 20 passes through the through hole on the cylinder cover 2 to connect with the moving ring 17.

[0030] In an optional embodiment, a plurality of limiting plates 21 are connected to the side of the moving ring 17 away from the cylinder cover 2; the limiting plates 21 are circumferentially distributed with the central axis of the cylinder cover 2 as the center. The shapes of the limiting plates 21 are all L-shaped. The longer lengths of the limiting plates 21 are closely attached to the surface of the diameter increasing plate 5, and when the diameter increasing plate 5 moves away from the main shaft 1, it guides and limits the diameter increasing plate 5.

[0031] In an optional embodiment, an installation groove 22 is formed on the arc surface of the arc-shaped plate 7, and an anti-slip layer is connected in the installation groove 22; the anti-slip layer is selected but not limited to a rubber layer.

[0032] In summary, when the present utility model is used, the material is installed from one end of the main shaft 1 away from the telescopic device 3 through an external transportation device. The material moves along the main shaft 1 and contacts the limiting plate 21 and the diameter increasing plate 5. The position of the coiled material on the main shaft 1 is limited by the limiting plate 21; when it is necessary to uniformly distribute the width of the coiled material and adjust the positions of the moving ring 17 and the limiting plate 21, the staff rotates the handle 19, which will drive the adjusting screw 18 to rotate. The adjusting screw 18 rotates in the threaded hole on the cylinder cover 2 and drives the moving ring 17 to move along the length direction of the main shaft 1, so that the positions of the moving ring 17 and the limiting plate 21 change to limit the coiled material. After the telescopic device 3 is started, it will stretch the main shaft 1 to move towards the cylinder cover 2. The support plate 4 on the main shaft 1 moves to contact the diameter increasing plate 5. The roller 6 on the diameter increasing plate 5 contacts the support plate 4. The top inclined support plate 4 pushes the sliding block 9 at one end of the diameter increasing plate 5 to move along the sliding groove 10 through the contact with the roller 6. When multiple diameter increasing plates 5 move simultaneously, the outer diameter of the arc-shaped plate 7 increases and gradually matches and clamps the inner diameter of the material; when it is necessary to obtain a larger or smaller angle, the staff inserts an inner hexagon wrench into the adjustment groove to drive the adjustment rod 13 to rotate. The rotating block 14 on the adjustment rod 13 rotates and contacts one end of the moving rod 15. The elastic member 16 rebounds and pushes the moving rod 15 to closely adhere to the rotating block 14. One end of the moving rod 15 moves away from the support plate 4. The support plate 4 is replaced through the sliding of the T-shaped block 11 and the T-shaped groove 12, and a support plate 4 with a larger or smaller angle is replaced, and then it is installed. Thus, a larger angle can be obtained when the distance remains unchanged, so that more sizes can be adjusted when the length of the main shaft 1 remains unchanged.

Various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those skilled in the relevant technical field.
