Description

Technical Field

[0001] The utility model relates to the technical field of label paper winding machines, in particular to a reel quick-disassembly structure of a label paper winding machine. Background Art

[0002] The label paper winder is a device used to wind label paper or similar film materials from a parent roll into a roll. In the winder, the winding drum is a key component, which plays an important role in supporting and transmitting the winding material. As a cylindrical structure, the winding drum provides a stable support platform so that the label paper or film material can be evenly wound. Through its own rolling motion, it helps the material on the parent roll to gradually wind into a roll with a larger diameter. The design of the quick-release structure is to simplify the operation and maintenance process of the winder, so that the operator can quickly and safely replace and maintain the roll, thereby reducing production downtime and improving equipment utilization. The current roll quick-release structure generally installs the roll on the inner shaft through a spline fit, and screws or bolts a support member for supporting the roll at the end of the inner shaft. If the threaded connection is not properly installed or tightened, the roll may loosen or fall off when running at high speed. Although the threaded connection is usually a common fixing method, its installation and removal also require more tools and time. Compared with the original intention of the quick-release structure design, it is not very convenient. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-6 The utility model provides an embodiment: a roll quick-release structure of a label paper winding machine, comprising a right-angle frame 1 and a ball bearing 2 installed on the outer wall of one side of the right-angle frame 1, and a central shaft 3 is rotatably installed inside the ball bearing 2, an outer spline roll sleeve 4 is fixed to the outer surface of the central shaft 3, and a rear baffle 5 is fixed to one end of the surface of the outer spline roll sleeve 4, and a plurality of convex hollow lock seats 10 distributed in an annular manner with equal intervals are installed on the surface of the rear baffle 5, an inner spline roll sleeve 6 is slidably sleeved on the surface of the outer spline roll sleeve 4, and a support plate 7 is installed at one end of the surface of the inner spline roll sleeve 6, a plurality of cylindrical grooves distributed in an annular manner are arranged on the surface of the rear baffle 5, and a convex column for mutual insertion with the cylindrical groove is installed on the back of the support plate 7;

[0021] The outer surface of the support plate 7 is provided with a hook-type elastic self-locking structure 9 for plugging with the convex hollow lock seat 10. A rotating pusher for forcing each hook-type elastic self-locking structure 9 to move synchronously is provided on the outer wall of the support plate 7 away from the rear baffle plate 5. The rotating pusher is a cam plate 11 rotatably installed on the surface of the support plate 7. The outer wall of the cam plate 11 is provided with an outer convex portion 1101 for contacting one end of the J-shaped lock hook 902.

[0022] The top of the right angle frame 1 is integrally formed with a longitudinal arm 101, and support rods 102 are installed on both sides of the top of the longitudinal arm 101. When the right angle frame 1 is installed, the right angle frame 1 can be connected to the wall panel of the label paper winding machine through the support rods 102, and the connection method can be welding;

[0023] Four rectangular ribs distributed in a ring-shaped cross are integrally formed on the outer wall of the outer spline winding sleeve 4, and rectangular rib grooves for sliding the rectangular ribs are arranged on the inner wall of the inner spline winding drum 6. The key grooves between the outer spline winding sleeve 4 and the inner spline winding drum 6 cooperate, so that when the outer spline winding sleeve 4 is driven, the inner spline winding drum 6 rotates together with the outer spline winding sleeve 4, so as to achieve the purpose of winding up the label paper;

[0024] The hook-type elastic self-locking structure 9 includes a rectangular convex plate 8 fixed at the edge of the support plate 7, a U-shaped seat 901 fixed on the surface of the rectangular convex plate 8, a J-shaped lock hook 902 slidably installed inside the U-shaped seat 901, and a spiral spring 904 fixed on the inner wall of one side of the U-shaped seat 901. The spiral spring 904 and the J-shaped lock hook 902 are concentrically mounted, and a convex rod 903 that penetrates the outside of the U-shaped seat 901 is fixed on one end of the surface of the J-shaped lock hook 902. One end of the spiral spring 904 abuts against the convex rod 903, and the other end of the J-shaped lock hook 902 is plugged into the convex hollow lock seat 10. The rear baffle 5 and the support plate 7 After the relative surfaces of the J-shaped locking hook 902 come into contact, the staff releases the cam plate 11, and the end of the J-shaped locking hook 902 is no longer subjected to force, and then the spiral spring 904 inside the U-shaped seat 901 begins to reset from a compressed state, and the spiral spring 904 pushes the J-shaped locking hook 902 to move through the convex rod 903 until the upper end of the J-shaped locking hook 902 is plugged into the convex hollow locking seat 10, so that the curved hook type elastic self-locking structure 9 and the convex hollow locking seat 10 are connected. This structural design is more intuitive and easy to operate, and the operator can master the locking and unlocking methods more quickly, reducing the connection failure that may be caused by operating errors;

[0025] A plum blossom handle is fixed at the edge of the surface of the cam disc 11 , and the cam disc 11 can be quickly rotated by the plum blossom handle on the surface of the cam disc 11 .

[0026] When the embodiment of the present application is in use, the right-angle frame 1 is first fixed to the point where the label paper winder is used to wind up the label paper, and then the staff takes out the inner spline winding drum 6 to be fitted with the outer spline winding drum sleeve 4, so that the outer spline winding drum sleeve 4 and the inner spline winding drum 6 are slid and fitted until the opposite surfaces of the rear baffle plate 5 and the support plate 7 contact each other. During this process, the staff needs to manually rotate the cam plate 11 so that the cam plate 11 forces each bent hook type elastic self-locking structure 9 to move synchronously through the outer convex portion 1101, so that the active end of the bent hook type elastic self-locking structure 9 does not contact the convex hollow lock seat 10, so as to avoid obstruction to the fitting operation of the outer spline winding drum sleeve 4 and the inner spline winding drum 6. When the outer spline winding drum sleeve 4 and the inner spline winding drum 6 are fitted to the extreme position, the staff releases the cam plate 11, and the bent hook type elastic self-locking structure 9 is reset and its active The moving end and the convex hollow lock seat 10 are plugged into each other, and a locking point is formed between the bent hook type elastic self-locking structure 9 and the convex hollow lock seat 10, thereby connecting the rear baffle plate 5 and the support plate 7, so that the outer spline reel sleeve 4 and the inner spline winding drum 6 are stably assembled together. Compared with traditional threaded or bolted fixation, the convex hollow lock seat 10 and the bent hook type elastic self-locking structure 9 can more firmly connect the outer spline reel sleeve 4 with the inner spline winding drum 6, and effectively prevent accidental loosening or falling off during the rotation of the shaft body, thereby ensuring the stability and operation safety of the equipment. The structural design coordination of the bent hook type elastic self-locking structure 9 and the convex hollow lock seat 10 also allows the operator to quickly lock and unlock without the need for complicated matching tools or extra time, which greatly saves the operation time of replacing the reel and achieves the purpose of fast disassembly and replacement of the reel.
