[0002] A winder is a machine that winds the material to be wound onto a shaft or sleeve into a roll by high-speed rotation, and the roll is then transported for other processing of the wound material. Due to the high rotation speed, problems are prone to occur in the installation of the bobbin of the winder, such as insufficient clamping force, insufficient balance accuracy of key components, or insufficient surface roughness of the clamping parts; or long braking time, which affects the working efficiency of the winder, generally due to excessive inertia.

[0038] The working principle and beneficial effects of the present invention are:

[0039] In order to solve the problems of bobbin loading, bobbin unloading and high-speed winding of the winding machine, a winding roller is specially designed. The elastic deformation of the second elastic member can realize the synchronous rotation and cancellation of the synchronous rotation of the bobbin and the first roller body and push the bobbin down.

The first elastic member and the pressure member can realize the second elastic member to tighten and loosen the bobbin, thereby realizing high-speed rotation, bobbin loading and bobbin withdrawal of the bobbin. The first elastic member transmits a trend of movement toward the blocking member to the second body. The sliding of the second body makes the first space smaller. The second elastic member located in the first space is deformed, tightening the bobbin, and realizing synchronous rotation of the bobbin and the first roller body. The pressure member drives the second body to move away from the blocking member, making the first space larger, and the second elastic member contracts and separates from the bobbin. In this way, the bobbin can be removed from the first roller body to prepare for bobbin withdrawal. Figure 3As shown, the bobbin is no longer on the second body and is about to be separated from the first roller body to complete the bobbin withdrawal operation. Through the cooperation of these elements, the automatic bobbin loading and bobbin withdrawal operations are realized. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0046] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] like Figure 1~Figure 3 As shown, this embodiment provides a winding roller, comprising

[0048] A first roller body, the tube is used to be sleeved on the first roller body;

[0049] The second body is movably arranged relative to the first roller body;

[0050] The stopper 3 is arranged on the first roller body, and a first space 11 is formed between the stopper 3 and the second body, and the first space 11 becomes larger or smaller after the stopper 3 and the second body move relative to each other;

[0051] A first elastic member 4, one end of which acts on the second body to make the first space 11 tend to become smaller;

[0052] A pressing member 5 is rotatably or movably arranged at one side of the second main body, and acts on the second main body after being rotated or moved, so that the first space 11 becomes larger;

[0053] The second elastic member 6 is arranged in the first space 11. When the first space 11 becomes larger or smaller, the second elastic member 6 is deformed to act on the inner wall of the bobbin, thereby realizing synchronous rotation of the two or canceling synchronous rotation.

[0054] In this embodiment, in order to solve the problems of bobbin loading, bobbin unloading and high-speed winding of the winding machine, a winding roller is specially designed. The bobbin and the first roller body are rotated synchronously and the synchronous rotation is canceled through the elastic deformation of the second elastic member 6, and the bobbin is pushed down. During operation, the bobbin loading process, the working process, the bobbin unloading preparation process and the bobbin unloading process are required. Figure 1 This is the working state of the winding roller when winding at high speed. Figure 2 In preparation for bobbin withdrawal, Figure 3 It is the bobbin retracting state.

[0055] In this embodiment, the rotation of the first roller body realizes the rotation and winding of the winding roller, and the first elastic member 4 transmits a movement trend to the second body, so that the second body moves axially, the first space 11 becomes smaller, and the second elastic member 6 is deformed. The first elastic member 4 and the pressing member 5 can realize the second elastic member 6 to tighten and loosen the bobbin, thereby realizing the high-speed rotation, loading and unloading of the bobbin. Figure 1 As shown, the first elastic member 4 transmits a tendency to move toward the stopper 3 to the second body, the second body slides to reduce the first space 11, and the second elastic member 6 in the first space 11 deforms to tighten the bobbin, thereby achieving synchronous rotation of the bobbin and the first roller. Figure 2 As shown, the pressing member 5 drives the second body to move away from the stopper 3, so that the first space 11 becomes larger, and the second elastic member 6 contracts and separates from the bobbin, so that the bobbin can be removed from the first roller body, and the bobbin is ready to be withdrawn. Figure 3 As shown, the bobbin is no longer on the second body and is about to be separated from the first roller body to complete the bobbin withdrawal operation. Through the cooperation of these elements, the automatic bobbin loading and bobbin withdrawal operations are realized.

[0056] Further, the pressing member 5 is rotatably arranged on one side of the second body;

[0057] The first slide bar 7 further includes: the first slide bar 7 has a groove 701 and a sliding surface 702; the groove 701 and the sliding surface 702 are connected; the groove 701 has a guide surface for facilitating the pressing member 5 to slide from the groove 701 to the sliding surface 702; after the first slide bar 7 moves, one end of the pressing member 5 extends into the groove 701 or slides on the sliding surface 702;

[0058] The pressing member 5 has at least the following two states after the first sliding rod 7 slides:

[0059] One end of the pressing member 5 extends into the groove 701, and the other end of the pressing member 5 acts on the second body;

[0060] One end of the pressing member 5 is on the sliding surface 702, and the pressing member 5 does not act on the second body.

[0061] In this embodiment, in order to achieve that the second elastic member 6 remains in a relaxed state when the bobbin is loaded and withdrawn, a first slide bar 7 is designed, and the pressing member 5 is arranged on one side of the first slide bar 7. Specifically, the first slide bar 7 has a groove 701 and a sliding surface 702. There are two states when the pressing member 5 slides on the first slide bar 7, one state when one end of the pressing member 5 is in the groove 701, and another state when one end of the pressing member is on the sliding surface 702. Figure 1 As shown, the second elastic member 6 holds the bobbin tightly, the first slide bar 7 does not move, and the pressing member 5 is stationary in the groove 701. At this time, the bobbin and the first roller body rotate synchronously. Figure 2 As shown, the first slide bar 7 moves toward the bobbin, and the groove 701 moves synchronously with the first slide bar 7. One end of the pressing member 5 is in the groove 701 and is rotated by the groove 701, thereby pushing the second body and driving the second body to move in the opposite direction of the stopper 3, so that the first space 11 becomes larger, thereby relaxing the second elastic member 6 and separating from the bobbin. Figure 3 As shown, the first slide bar 7 continues to move toward the bobbin direction, and the pressing piece 5 slides from the groove 701 through the guide surface to the sliding surface 702. After sliding onto the sliding surface 702, the pressing piece 5 no longer rotates and always maintains the position when it last slid out of the groove 701. The pressing piece 5 no longer continues to push the second main body, so that the first space 11 always maintains the size when the pressing piece 5 slides out of the groove 701, and the first elastic piece 6 no longer deforms and remains in a relaxed state, which is convenient for the operation of loading and unloading the bobbin.

[0062] Furthermore, it also includes a first linear driving device 8, wherein an output end of the first linear driving device 8 abuts against the first sliding rod 7 to drive the first sliding rod 7 to move;

[0063] A second sliding bar 9, one end of which is provided with a push plate 901, and the push plate 901 is connected to the first sliding bar 7;

[0064] The second linear drive device 10, the second slide bar 9 is arranged on the output end of the second linear drive device 10, driving the second slide bar 9 to move. After the second slide bar 9 moves, the push plate 901 pushes the tube off the first roller body, and during the pushing process, one end of the pressing piece 5 slides on the sliding surface 702.

[0065] In this embodiment, the first linear drive device 8 and the second linear drive device 10 can be a cylinder, an electric cylinder, or a hydraulic cylinder. Figure 1As shown, the first linear drive device 8 drives the first slide bar 7 to slide, and the output end of the first linear drive device 8 abuts against the first slide bar 7. After the pressure piece 5 slides to the sliding surface 702, the first linear drive device 8 reaches the maximum stroke and separates from the first slide bar 7, and no longer drives the first slide bar 7 to slide. Figure 2 As shown, after the first linear drive device 8 stops working, the second linear drive device 10 can start working, driving the second slide bar 9 to slide in the direction of the bobbin. The second slide bar 9 is linked with the first slide bar 7 through the push plate 901, driving the first slide bar 7 to slide. During this process, the pressure piece 5 keeps sliding on the sliding surface 702, so that the second body is no longer pushed by the pressure piece 5, the size of the first space 11 remains unchanged, the second elastic member 6 remains in a relaxed state, and the second slide bar 9 pushes the push plate 901 to push the bobbin out. Through the combination of the first linear drive device 8 and the second linear drive device 10, it is possible to safely and efficiently realize the bobbin first relaxation and then withdrawal, as well as various combinations of bobbin loading methods. At the same time, setting up two drive devices can also quickly realize the bobbin installation state, which only requires the second linear drive device 10 to be fully retracted and the first linear drive device 8 to be fully extended.

[0066] Further, the second body includes a support seat 201, the support seat 201 is arranged on one side of the first elastic member 4, and the first elastic member 4 acts on the support seat 201;

[0067] The second connecting roller 202 is slidably disposed on the support seat 201 and is also slidably disposed on the first roller body, a first space 11 is formed between the second connecting roller 202 and the stopper 3, and a second space 12 is formed between the second connecting roller 202 and the support seat 201;

[0068] The third elastic member 203 is disposed in the second space 12 and is used to deform after the second space 12 becomes larger or smaller, and to act on or cancel the effect on the bobbin.

[0069] In this embodiment, the first elastic member 4 acts on the support seat 201, and transmits pressure to the second connecting roller 202 through the support seat 201, so that the second connecting roller 202 slides on the first roller body. The second connecting roller 202 forms a first space 11 with the stopper 3, and forms a second space 12 with the support seat 201, so that more elastic members can be arranged in both spaces, ensuring the stability of the elastic members in the process of tightening and loosening the bobbin, and preventing a problem with an elastic member from causing the bobbin to be thrown out and injuring people. At the same time, the second elastic member 6 and the third elastic member 203 use tension springs of the same specifications, so that their deformation sizes can be kept consistent, so that the winding roller is not prone to problems in the winding and unwinding of the winding roller.

[0070] Furthermore, the second body further includes a limiting space 204, which is arranged on the second connecting roller 202, and there are two limiting spaces 204;

[0071] There are two limiting members 205 , one limiting member 205 is set on the support seat 201 , one end of which extends into a limiting space 204 and moves in the limiting space 204 , and the other limiting member 205 is set on the first roller body, one end of which extends into another limiting space 204 and moves in the limiting space 204 .

[0072] In this embodiment, the limiting member 205 is a screw, which is arranged on the support seat 201. The support seat 201 can also be subdivided into three parts, and the sliding tracks of the three parts are consistent. One end of the limiting member 205 extends into the limiting space 204 on the second connecting roller 202. The first elastic member 4 drives the support seat 201 to slide, and the support seat 201 drives the second connecting roller 202 to move, so that the size of the first space 11 and the second space 12 changes, thereby realizing the tightening and relaxation of the second elastic member 6 and the third elastic member 203.

[0073] The support seat 201, the second connecting roller 202, the second elastic member 6, the third elastic member 203 and the limiting member 205 form a whole, namely the second body, which realizes the smooth movement of the second body and enables the second body to rotate and wind at high speed with the first roller body. The existence of the limiting member 205 ensures that the deformation size of the second elastic member 4 and the third elastic member 6 remains consistent each time, thereby improving the installation stability of the bobbin.

[0074] Further, the support seat 201 is slidably disposed on the first roller body;

[0075] The other end of the first elastic member 4 acts on the first roller body.

[0076] In this embodiment, the first elastic member 4 is a compression spring, which mainly bears pressure, and the pressure is relatively large, and a support seat 201 is required to fix its position and transmit its pressure. One end of the first elastic member 4 is set inside the support seat 201, and the other end can not only act on the fixed frame or wall, but also be connected to the fixed part on the first roller body, so that the first elastic member 4 will not move after being stressed and can well transmit the movement trend. Similarly, it can be reasonably inferred that the first elastic member 4 is designed as a tension spring to achieve the purpose of the present invention.

[0077] Furthermore, the support seat 201 has a pushing portion 2011, and the pushing portion 2011 is adjacent to the pressing member 5. After the pressing member 5 rotates, it pushes the pushing portion 2011 to slide, thereby pushing the second body to move.

[0078] In this embodiment, in order to facilitate the pressure piece 5 to act on the second body, a push portion 2011 is provided on the support seat 201. Figure 2 As shown, one end of the pressing member 5 is behind the pushing portion 2011, and the pressing member 5 can push the pushing portion 2011 by rotating, and the pushing portion 2011 can drive the second body to slide, and the movement of the second body is achieved by using a simple pushing portion 2011.

[0079] Further, the first roller body includes a rotating shaft 101, the rotating shaft 101 passes through the second body, and the stopper 3 is arranged on the rotating shaft 101;

[0080] The rotating roller 102 is disposed on the rotating shaft 101 , and the rotating shaft 101 drives the rotating roller 102 to rotate.

[0081] In this embodiment, the first roller body is composed of a rotating shaft 101 and a rotating roller 102, and the rotating roller 102 is connected to the rotating shaft 101 by bolts, so that the rotating shaft 101 drives the rotating roller 102 to rotate, and the second body is also a roller body. The rotating shaft 101 is arranged inside the second body, and the rotating roller 102 is arranged on one side of the rotating shaft 101. The stopper 3 is arranged on the rotating shaft 101, and there is only a pipe sleeve on the outside of the rotating roller 102. In this way, the rotating roller 102 can be disassembled without disassembling the rotating shaft, and the rotating roller 102 can be replaced as needed, which facilitates the disassembly and maintenance of the rotating roller 102.

[0082] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
