Description

Technical Field

[0001] This utility model relates to the technical field of adhesive label printing machines, specifically to an adjustable fixed roller for adhesive label printing machines. Background Technology

[0002] Labels are composite materials with paper, film or special materials as the surface material, an adhesive coating on the back to form an adhesive layer, and silicone-coated protective paper as the base paper. After processing such as printing and die-cutting, they become finished labels. In adhesive label printing equipment, the fixed roller is one of the important components. Existing adhesive label printing machines usually place the fixed roller at the end of the machine body to perform the winding of the adhesive labels.

[0003] Chinese Patent CN221366193U discloses an adjustable fixed roller for an adhesive label printing machine. The roller includes a machine body, with guide rollers and a fixed roller located at the upper and lower ends of the frame. Positioning rods, slidably connected to the fixed ring, are located at both the upper and lower ends of the back side of the limiting ring. This adjustable fixed roller allows for adaptive adjustment of the winding width according to the size and width of the adhesive label, thus limiting the width of the label on both sides, ensuring winding quality, and offering greater adaptability.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: due to the setting of the limiting rings on the left and right sides of the outer circumference of the fixed roller, it is not easy to separate the adhesive label paper from the fixed roller after winding. When it is necessary to wind a new roll of adhesive label paper, the fixed roller needs to be disassembled and replaced with an empty fixed roller, which reduces the winding efficiency and causes inconvenience to use. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an easily adjustable fixed roller for an adhesive label printing machine.

[0018] Example 1

[0019] like Figures 1 to 4 As shown, the present invention proposes an adjustable fixed roller for an adhesive label printing machine, comprising a rotating rod 1, a sleeve 2, a driving mechanism, a moving plate 5, and an abutment plate 501. One end of the rotating rod 1 is connected to the end of the adhesive label printing machine body via a power source, while the other end is not connected to the machine body. The sleeve 2 is adjustablely slidably fitted outside the rotating rod 1, and a protective cover 3 is installed on the outside of the sleeve 2. A limit ring 304 is installed on the outer wall of the protective cover 3 near the abutment plate 501 to protect the adhesive label. The driving mechanism is located between the protective cover 3 and the sleeve 2. Multiple sets of moving plates 5 are provided, and the moving plates 5 are L-shaped. The multiple sets of moving plates 5 are evenly distributed around the outside of the sleeve 2, and the multiple sets of moving plates 5 are driven by the driving mechanism to move closer to or away from the sleeve 2. The abutment plate 501 is installed on the moving plate 5 at the end away from the driving mechanism, and the other end of the abutment plate 501 extends to the outside of the protective cover 3 and is slidably connected to the side end of the protective cover 3.

[0020] Furthermore, multiple sets of adjusting grooves 101 are evenly provided on the rotating rod 1, and a limiting hole 201 is provided on the sleeve 2 on the side away from the take-up drum. The limiting hole 201 is connected to one of the adjusting grooves 101 by bolts. By rotating the bolts to separate them from the adjusting grooves 101, the sleeve 2 can be driven to slide laterally along the rotating rod 1 a suitable distance, thereby driving the take-up drum to be adjusted on the rotating rod 1. By fixing the limiting hole 201 to the adjusting groove 101 at the appropriate position by bolts, the take-up drum can be limited and wound up.

[0021] Furthermore, the inner wall of the sleeve 2 is provided with a raised strip, and the outer wall of the rotating rod 1 is provided with a sliding groove. The raised strip and the sliding groove are slidably connected. The setting of the raised strip makes it easy to keep the sleeve 2 sliding and adjusting along the stable horizontal direction of the rotating rod 1, and avoids rotation interference between the limiting hole 201 and the adjusting groove 101.

[0022] Furthermore, the drive mechanism includes a rotating seat 4, a rotating handle 404, and a screw 405; the rotating seat 4 is rotatably connected to the outer wall of the sleeve 2, and a first bevel gear 401 is installed at one end of the outer wall of the rotating seat 4, and a driven gear 402 is installed at the other end; the rotating handle 404 is rotatably connected to the annular plate at the left end of the protective cover 3, and a driving gear 403 is installed at one end of the rotating handle 404 inside the protective cover 3. The driving gear 403 meshes with the driven gear 402, and a nut (not shown) is threaded onto the outer wall of the rotating handle 404. The nut abuts against the protective cover 3 to limit the rotating handle 404 and prevent it from rotating easily; multiple sets of screws 405 are provided, and multiple sets of screws 405 are evenly rotatably connected to the inner wall of the protective cover 3. A second bevel gear 406 is installed on the screw 405 at the end away from the protective cover 3. The second bevel gear 406 meshes with the first bevel gear 401, and the moving plate 5 is threaded onto the outer wall of the screw 405.

[0023] Furthermore, a limiting plate 302 is installed on the inner wall of the protective cover 3. The limiting plate 302 is sleeved on the outer wall of the sleeve 2. Multiple sets of limiting ports 303 are evenly opened on the limiting plate 302. The moving plate 5 passes through the limiting plate 302 and is slidably connected with the limiting ports 303. The limiting plate 302 is used to support the protective cover 3 and improve its overall strength.

[0024] In this embodiment, one end of the rotating rod 1 is mounted on the body of the adhesive label printing machine and connected to the power source. The sleeve 2 is fitted onto the outer wall of the rotating rod 1 and moved to a suitable position along the outer wall of the rotating rod 1. The limiting hole 201 is fixedly connected to the adjusting groove 101 in a suitable position by bolts. Rotating the handle 404 drives the drive gear 403 to rotate, causing the screw 405 meshing with it to rotate, which in turn drives the rotating seat 4 to rotate along the sleeve 2, thereby driving the first bevel gear 401 to rotate, causing the multiple sets of second bevel gears 406 meshing with it to rotate, which in turn drives the corresponding screws 405 to rotate. Since the moving plate 5 is slidably connected to the limiting port 303 on the limiting plate 302, when the screw 405 rotates, it drives the moving plate 5 to slide along the limiting port 303, causing the multiple sets of moving plates 5 to move towards the sleeve 2. The rotating rod 1 is moved closer to the rotating rod 1, causing multiple sets of abutment plates 501 to move towards the outer wall of the rotating rod 1. At this time, the take-up drum of the adhesive label can be moved around the outside of the rotating rod 1 until the take-up drum moves outside the multiple sets of abutment plates 501 and one end of the take-up drum abuts against the protective cover 3. Then, the rotating handle 404 is rotated in the opposite direction to make the multiple sets of abutment plates 501 move away from each other until the multiple sets of abutment plates 501 clamp the inner wall of the take-up drum. The outer wall of the abutment plate 501 is provided with an anti-slip pad to increase the friction between the abutment plate 501 and the take-up drum and prevent slippage. The rotating rod 1 is driven to rotate by the power source, which can drive the limited take-up drum to rotate and roll up the adhesive label. After the roll-up is completed, the rotating handle 404 is rotated to make the multiple sets of abutment plates 501 move closer to each other and away from the take-up drum, so that the take-up drum with the adhesive label wrapped around it can be removed from the rotating rod 1, making unloading more convenient and faster.

[0025] Example 2

[0026] like Figures 1 to 3 As shown, the present invention proposes an adjustable fixed roller for an adhesive label printing machine. Compared with Embodiment 1, the protective cover 3 is composed of a tube body and an annular plate that is detachably installed at both ends of the tube body by bolts. The inner wall of the annular plate is detachably connected to the outer wall of the sleeve 2 by bolts.

[0027] In this embodiment, a clearance opening 301 is provided on the annular plate at the right end of the protective cover 3. The abutment plate 501 is slidably connected to the clearance opening 301. The annular plate is detachably connected to the protective cover 3 and the sleeve 2, which facilitates disassembly for inspection of internal components.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
