Description

Technical Field

[0001] This utility model relates to the field of fabric winding technology, and in particular to an automatic roll changing device for a winding equipment. Background Technology

[0002] In the field of fabric production technology, after fabric production is completed, it needs to be wound. Traditional fabric winding equipment is usually equipped with only one winding roller, which is connected to a drive mechanism for winding. When only one winding roller is provided, after the fabric roll on the winding shaft is finished, the machine needs to be stopped to unload the material and replace it with a new winding drum, resulting in low production efficiency.

[0003] To address the aforementioned issues, the field currently equips the unloading end of the production line with at least two winding shafts and correspondingly sets two drive mechanisms. This allows the fabric roll on one winding shaft to be wound onto another idle winding shaft for further winding after the roll has been wound up. Simultaneously, the operator can unload the wound fabric roll without stopping production.

[0004] However, in existing multi-spindle winding equipment, when the fabric is switched between two winding shafts, it is usually cut manually with a knife, which poses certain safety hazards. In addition, manual cutting is slow and affects production efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an automatic winding device for winding equipment, which improves winding switching efficiency while enhancing safety.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] Furthermore, the first winding mechanism, the second winding mechanism, and the conveying roller each have a first winding area, a second winding area, and a conveying area; in the direction of movement of the cutting mechanism, the edges of the first winding area and the second winding area are respectively flush with the edges of the conveying area.

[0009] Furthermore, in a direction perpendicular to the cutting mechanism in the horizontal plane, there is a gap between the first winding mechanism and the second winding mechanism.

[0010] Furthermore, the cutting end of the cutting mechanism can extend between the second winding mechanism and the conveying roller and press against the fabric located on the conveying roller.

[0011] Furthermore, it also includes sensing components; in the direction of movement of the cutting mechanism, a sensing component is respectively provided at both ends of the conveying area, and the sensing end of the sensing component can be arranged opposite to the moving end of the cutting mechanism.

[0012] Furthermore, the winding equipment includes a frame and a roll changing platform; the first winding mechanism, the second winding mechanism, the cutting mechanism and the roll changing platform are respectively disposed on the frame.

[0013] Furthermore, the first winding mechanism includes a first lifting mechanism and a first winding roller;

[0014] The first winding roller is mounted on the movable end of the first lifting mechanism; the fixed end of the first lifting mechanism is connected to the frame; when the first winding roller presses against the conveying roller, the first winding roller rotates.

[0015] Furthermore, the second winding mechanism includes a second lifting mechanism and a second winding roller; the second winding roller is mounted on the movable end of the second lifting mechanism; the fixed end of the second lifting mechanism is connected to the frame; when the second winding roller presses against the conveying roller, the second winding roller rotates.

[0016] Furthermore, the roll changing platform includes a lifting mechanism and a support member; the support member is connected to the movable end of the lifting mechanism, and the support member is arranged adjacent to the conveyor roller; when the lifting mechanism descends, the top of the support member is lower than the top of the conveyor roller;

[0017] The support member is used to receive the fabric roll wound outside the first winding mechanism.

[0018] Furthermore, the cutting mechanism includes a cutting component and a linear drive component; the linear drive component is mounted on the frame; the fixed end of the cutting component is connected to the linear drive component in a transmission manner, and the movable end of the cutting component is positioned toward the side where the second winding mechanism is located.

[0019] The beneficial effects of this invention are as follows: by bringing the first and second winding mechanisms into contact with the conveyor rollers, the first and second winding mechanisms are driven to rotate; by providing a cutting mechanism, the material is automatically cut after the first winding mechanism has finished winding, and then automatically wound up by the second winding mechanism, replacing manual cutting. Furthermore, since the first and second winding mechanisms directly contact the conveyor rollers for winding, compared to existing technologies, no driving mechanism is required, resulting in a simpler structure and enabling rapid unloading of fabric rolls, thus improving production efficiency.

[0032] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0033] Please refer to Figures 1-4 An automatic roll-changing device for a winding machine is disclosed. The winding machine includes a conveyor roller 1 for conveying fabric, a first winding mechanism 2, a second winding mechanism 3, and a cutting mechanism 4. At least one of the first winding mechanism 2 and the second winding mechanism 3 presses against the conveyor roller 1 to wind the fabric onto the first winding mechanism 2 or the second winding mechanism 3. The cutting mechanism 4 is disposed on the side of the second winding mechanism 3 away from the first winding mechanism 2, and the moving direction of the cutting mechanism 4 is parallel to the first winding mechanism 2 and the second winding mechanism 3, respectively. The cutting mechanism 4 is used to cut the fabric wound on the first winding mechanism 2 when the second winding mechanism 3 presses against the conveyor roller 1.

[0034] Understandably, by setting up a cutting mechanism 4, the material is automatically cut after the first winding mechanism 2 has finished winding, and then automatically wound up by the second winding mechanism 3, replacing manual cutting. Furthermore, the first winding mechanism 2 and the second winding mechanism 3 directly contact the conveyor roller 1 for winding, which, compared to existing technologies, eliminates the need for a drive mechanism, resulting in a simpler structure and enabling rapid unloading of the fabric roll 8, thus improving production efficiency.

[0035] In some embodiments, the first winding mechanism 2, the second winding mechanism 3, and the conveying roller 1 each have a first winding region 21, a second winding region 31, and a conveying region 41; in the direction of movement of the cutting mechanism 4, the edges of the first winding region 21 and the second winding region 31 are flush with the edges of the conveying region 41, respectively. It is worth noting that the widths (i.e., the dimensions in the direction of movement of the cutting mechanism 4) of the first winding region 21, the second winding region 31, and the conveying region 41 depend on the width of the fabric.

[0036] In some embodiments, there is a gap between the first winding mechanism 2 and the second winding mechanism 3 in a direction perpendicular to the cutting mechanism 4 in the horizontal plane, providing sufficient space for the fabric to be switched onto the second winding mechanism 3, and ensuring the effectiveness of the switching action.

[0037] In some embodiments, the cutting end of the cutting mechanism 4 can extend between the second winding mechanism 3 and the conveying roller 1 and press against the fabric located on the conveying roller 1 to ensure that the fabric can be completely cut.

[0038] In some embodiments, a sensing component 5 is further included; a sensing component 5 is respectively provided at both ends of the conveying area 41 in the direction of movement of the cutting mechanism 4, and the sensing end of the sensing component 5 can be arranged opposite to the moving end of the cutting mechanism 4. Specifically, the sensing component 5 is located outside both ends of the conveying area 41. The sensing component 5 is used to sense the position of the cutting mechanism 4. When the operator controls the first winding mechanism 2 to unload, it can determine whether to control the first winding mechanism 2 to separate from the conveying roller 1 based on the detection result of the sensing component 5. Further, when the sensing component 5 located at the end of the running trajectory of the cutting mechanism 4 senses the cutting mechanism 4, it sends a signal to the control center. When the operator starts the unloading program, the first winding mechanism 2 performs the unloading action; conversely, when the sensing component 5 does not sense the cutting mechanism 4, when the operator starts the unloading program, the first winding mechanism 2 does not perform the unloading action until the sensing component 5 senses the cutting mechanism 4 and then performs the unloading action.

[0039] In some embodiments, the winding equipment includes a frame 6 and a roll changing platform 7; the first winding mechanism 2, the second winding mechanism 3, the cutting mechanism 4 and the roll changing platform 7 are respectively disposed on the frame 6.

[0040] In some embodiments, the first winding mechanism 2 includes a first lifting mechanism 22 and a first winding roller 23; the first winding roller 23 is mounted on the movable end of the first lifting mechanism 22; the fixed end of the first lifting mechanism 22 is connected to the frame 6; when the first winding roller 23 presses against the conveying roller 1, the first winding roller 23 rotates. Specifically, the first lifting mechanism 22 includes two symmetrically arranged first drive motors and two symmetrically arranged first lifting arms 221. The first drive motors are connected to the input ends of the first lifting arms 221. The two ends of the first winding roller 23 are respectively mounted on the movable ends of the corresponding first lifting arms 221. The movable ends of the first lifting arms 221 are provided with first limiting hooks 222 for limiting the first winding roller 23. The working principle of the first winding mechanism 2 is as follows: When the first winding roller 23 is winding, the first drive motor controls the first lifting arm 221 to lift, so that the two ends of the first winding roller 23 press against the first lifting arm 221, and the first winding roller 23 contacts the conveyor roller 1. The conveyor roller 1 applies driving force to the first winding roller 23, and the fabric is automatically wound on the first winding roller 23. When the first winding roller 23 is finished winding, as the diameter of the fabric roll 8 continues to increase, the first winding roller 23 will move along the surface of the first lifting arm 221 and fall into the first limit hook. At this time, the operator issues a winding command through the control center. After the first winding mechanism 2 receives the command to execute the unloading action, if the cutting mechanism 4 has already completed the cutting action, the first drive motor controls the first lifting arm 221 to descend, and the fabric roll 8 located on the first winding roller 23 is separated from the conveyor roller 1.

[0041] In some embodiments, the second winding mechanism 3 includes a second lifting mechanism 32 and a second winding roller 33; the second winding roller 33 is mounted on the movable end of the second lifting mechanism 32; the fixed end of the second lifting mechanism 32 is connected to the frame 6; when the second winding roller 33 abuts against the conveyor roller 1, the second winding roller 33 rotates. Specifically, the second lifting mechanism 32 includes a second drive motor 321 and a second lifting arm 322, the second drive motor 321 is connected to the input end of the second lifting arm 322, the two ends of the second winding roller 33 are respectively mounted on the movable ends of the corresponding second lifting arms 322, and the movable end of the second lifting arm 322 is provided with a second limiting hook 323 for limiting the second winding roller 33. The tilting direction of the second lifting arm 322 is opposite to that of the first lifting arm 221, and before the first winding roller 23 and the second winding roller 33 are switched, the tilting direction of the first lifting arm 221 and the tilting direction of the second lifting arm 322 form an angle of less than or equal to 100°. The working principle of the second winding mechanism 3 is as follows: Before the second winding roller 33 performs the winding action, the second winding roller 33, on which the winding cylinder is sleeved, is manually mounted on the second lifting arm 322. That is, both ends of the second winding roller 33 are respectively embedded in the corresponding second limit hooks 323. After the first winding roller 23 finishes winding, the changing action is manually initiated. That is, the second drive motor 321 controls the second lifting arm 322 to rotate away from the first winding mechanism 2, so that the second lifting arm 322 descends and contacts the fabric. The fabric drives the second winding roller 33 to rotate. Then, the cutting mechanism 4 is activated to cut the fabric. After the fabric is cut, the unwound part will automatically be wound onto the second winding roller 33, completing the changing action. Preferably, the first winding roller 23 and the second winding roller 33 are both expansion shafts. By setting the first winding mechanism 2 and the second winding mechanism 3, the automatic roll changing action can be realized during the fabric winding process. The first winding roller 23 and the second winding roller 33 are both rotated by the force of the conveyor roller 1 and the fabric. Compared with the prior art, there is no need to connect with the drive mechanism, which makes the drive structure simpler and reduces the difficulty of changing the winding drum and unloading the fabric roll 8.

[0042] In some embodiments, the roll-changing platform 7 includes a lifting mechanism 71 and a support member 72; the support member 72 is connected to the movable end of the lifting mechanism 71 and is disposed adjacent to the conveyor roller 1; when the lifting mechanism 71 descends, the top of the support member 72 is lower than the top of the conveyor roller 1; the support member 72 is used to receive the fabric roll 8 wound around the first winding mechanism 2. When the first winding mechanism 2 controls the fabric roll 8 to unload, the fabric roll 8 will descend, and the lifting mechanism 71 will control the support member 72 to rise, so that the fabric roll 8 falls onto the support member 72, so that the subsequent unloading operation can be performed manually.

[0043] In some embodiments, the cutting mechanism 4 includes a cutting component 42 and a linear drive component 43; the linear drive component 43 is mounted on the frame 6; the fixed end of the cutting component 42 is connected to the linear drive component 43, and the movable end of the cutting component 42 faces the side where the second winding mechanism 3 is located. The linear drive component 43 drives the cutting component 42 to move rapidly along the axial direction of the second winding roller 33 to cut the fabric. Specifically, as the linear drive component 43 drives the cutting component 42 to move, the fabric is gradually cut, and thus the fabric will gradually wind onto the second winding roller 33 as it rotates. Optionally, the linear drive component 43 can be a linear module, a screw drive mechanism, or a synchronous belt slide. Preferably, the linear drive component 43 is a linear module.
