Detailed Embodiment
[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0021] Embodiment
[0022] Refer to Figures 1-4, a cowhide roll winding device, including a mounting frame body 1. An installation shaft 2 is rotatably installed in the mounting frame body 1. A winding drum 3 located inside the mounting frame body 1 is fixed on the installation shaft 2. An auxiliary component used in cooperation with the winding drum 3 is arranged on the mounting frame body 1. The auxiliary component includes a U-shaped bracket 4 inserted into the top of the inner cavity of the mounting frame body 1 and attached to the core of the winding drum 3. The bottom of the U-shaped bracket 4 is of a cylindrical structure. A fixed grip is fixed to the right end of the installation shaft 2. The U-shaped bracket 4 with a cylindrical bottom structure can better press the cowhide roll. And the design of the fixed grip facilitates the user to rotate the installation shaft 2 and the winding drum 3. Both ends of the U-shaped bracket 4 penetrate through the mounting frame body 1 and are fixed with a top plate 5. L-shaped lifting plates 8 are fixed on both sides of the front and back of the U-shaped bracket 4. Extension plates are fixed on both sides of the top of the front and back of the mounting frame body 1. The top end of the L-shaped lifting plate 8 penetrates through the extension plate and is fixed with a convex plate. By setting the L-shaped lifting plate 8, the extension plate and the convex plate, the U-shaped bracket 4 can be slidably limited, improving the stability of the U-shaped bracket 4 during movement and avoiding excessive inclination, which affects the pressing effect of the U-shaped bracket 4 on the cowhide roll;
[0023] Two groups of T-shaped rods 6 are symmetrically inserted into the top plate 5 along the left-right direction. A first spring 7 is wound around each group of T-shaped rods 6, and both ends of the first spring 7 are fixed to the protruding ends of the T-shaped rods 6 and the top plate 5. Multiple groups of teeth 9 are evenly fixed on the surface of one end of the winding drum 3. An auxiliary shaft 10 is rotatably installed at the top of the right side of the mounting frame body 1. A gear 11 and a ratchet 12 are sequentially fixed to both ends of the auxiliary shaft 10 along the left-right direction. A square column 22 is fixed to the top of the right inner cavity of the mounting frame body 1. An auxiliary bearing used in cooperation with the auxiliary shaft 10 is embedded in the square column 22. The design of the square column 22 and the auxiliary bearing improves the overall stability of the auxiliary shaft 10 and avoids the excessive length of the suspended part at one end of the auxiliary shaft 10 affecting the rotation stability. The meshing sides of the gear 11 and the teeth 9 are close to each other. A positioning shaft 13 is rotatably installed on the right side of the mounting frame body 1. A pawl 14 meshing with the ratchet 12 is fixed on the positioning shaft 13. A second spring 15 is fixed to the front of the pawl 14, and one end of the second spring 15 is fixed to the mounting frame body 1 through a support plate. A mounting plate 16 is fixed to the right end of the positioning shaft 13. A T-shaped limiting rod 17 is inserted into the mounting plate 16, and the left end of the T-shaped limiting rod 17 penetrates into the mounting frame body 1. An elastic sleeve 18 is fixed on the T-shaped limiting rod 17. One end of the elastic sleeve 18 is of a semi-circular structure. The design of the elastic sleeve 18 utilizes its elastic performance to improve the stability of the T-shaped limiting rod 17 during insertion and avoid its easy detachment from the mounting frame body 1. And the design of the semi-circular structure at one end facilitates the unobstructed insertion of the T-shaped limiting rod 17 and the elastic sleeve 18 into the mounting frame body 1;
[0024] Elastic binding straps 19 are provided on both sides of the bottom of the back surface of the U-shaped bracket 4. Guide seats 21 that cooperate with the elastic binding straps 19 are fixed on both sides of the top of the back surface of the mounting frame body 1. The design of the guide seats 21 prevents the elastic binding straps 19 that move with the U-shaped bracket 4 from being overly worn by the mounting frame body 1. One end of each group of elastic binding straps 19 is fixed with a cross card seat 20 inserted on the top plate 5. By providing an auxiliary component, the winding drum 3 after winding can be quickly positioned. And in cooperation with the elastic binding straps 19, the wound kraft paper roll can be integrally bound, and in cooperation with the cross card seat 20, the bound elastic binding straps 19 can be positioned, so that one end of the wound kraft paper roll can be completely attached to the wound kraft paper roll, and in cooperation with the winding drum 3 that remains in a fixed state as a whole, it can effectively prevent the wound kraft paper roll from being easily loosened.
[0025] In the present utility model, the user rotates the mounting shaft 2, which will drive the winding drum 3 to rotate synchronously to wind the kraft paper roll. By using the meshing of the teeth 9 and the gear 11 and with the cooperation of the auxiliary shaft 10, the ratchet 12 can be driven to rotate in the opposite direction to the winding drum 3. And under the elastic action of the second spring 15, a driving force can be continuously applied to the pawl 14, so that the pawl 14 can remain engaged with the ratchet 12, thereby quickly forming a locking and limiting structure for the winding drum 3 to limit the rotation direction of the winding drum 3 and prevent the winding drum 3 from rotating back. At the same time, by using the elastic rebound of the first spring 7, a downward pressure can be continuously applied to the U-shaped bracket 4, so that the U-shaped bracket 4 can continuously press on the kraft paper roll, further preventing the kraft paper roll from being easily loosened during winding. After the winding of the kraft paper roll is completed, one end of the kraft paper roll cannot be directly fixed to the wound kraft paper roll. At this time, the user inserts the T-shaped limiting rod 17 and the elastic sleeve 18 on the mounting frame body 1, and uses the elastic rebound of the elastic sleeve 18 to make the T-shaped limiting rod 17 clamped more tightly, thereby limiting the pawl 14 and further fixing the winding drum 3. Then the user removes the cross card seat 20 from the top plate 5, passes the elastic binding strap 19 around the bottom of the wound kraft paper roll from the back surface and then to the front surface, and at the same time, the cross card seat 20 is clamped on the top plate 5 again from the front surface, so that the wound kraft paper roll can be integrally bound, and one end of the wound kraft paper roll can be completely attached to the wound kraft paper roll, and in cooperation with the winding drum 3 that remains in a fixed state as a whole, it can effectively prevent the wound kraft paper roll from being easily loosened.
[0026] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
