Description

Technical Field

[0001] This utility model relates to the field of automated equipment, and in particular to a winding mechanism with high stability. Background Technology

[0002] In the production of roll products such as films, paper, and textiles, there are unwinding devices, tension adjustment devices, slitting devices, and winding devices. Each device can perform a corresponding function, and devices can be added or removed according to actual functional requirements to meet production needs.

[0003] The prior art (announcement number: CN 218968323 U, announcement date: 2023.05.05) discloses a roller limiting mechanism and a winding and unwinding mechanism having the same, which realizes the limiting and replacement of the roller by means of a rotating connection between the limiting member and the base, without the need for tools.

[0004] The above solution requires a handle to drive the limiting component to press the roller. The pressure of manual operation is difficult to maintain, which can easily lead to inconsistent winding quality during the winding operation. In addition, in the existing winding device, the position of the winding roller is fixed, and it needs to be used in conjunction with the pressing roller to press the roll material onto the winding roller for winding. However, as the roll material continues to wrap around the winding roller, the pressure of the pressing roller on the roll material will gradually increase, which will also lead to inconsistent winding quality of the roll material and affect the production yield of the roll material. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model provides a technical solution that can solve the above problems.

[0006] A highly stable winding mechanism includes a frame on which a conveyor belt is fixedly mounted. Positioning cabinets are provided on both the front and rear sides of the frame, and the conveyor belt is positioned between the two positioning cabinets.

[0007] The positioning cabinet is fixedly equipped with a lifting unit. A winding roller is rotatably installed between the lifting units of the two positioning cabinets. The winding roller has a roll of material wound on it. When the winding roller is winding, the bottom side of the roll of material is always against the conveyor belt.

[0008] Furthermore: the lifting unit includes a lifting motor, a chain assembly, a lifting platform, a roller frame, and two vertical screws; the lifting motor is fixedly installed inside the positioning cabinet, the two vertical screws are rotatably fitted on the left and right sides of the positioning cabinet respectively, the chain assembly is fitted on the rotor of the lifting motor and the bottom end of the two vertical screws, and the lifting motor drives the two vertical screws to rotate synchronously through the chain assembly; lifting blocks are fixedly installed on both sides of the lifting platform, the lifting blocks are formed with threaded holes, the vertical screws are screwably fitted into the threaded holes one by one, the roller frames are fixedly installed on the lifting platform one by one, and the take-up rollers are rotatably fitted onto the roller frames of the two lifting platforms.

[0009] Furthermore: a support plate is fixedly installed at the bottom of the positioning cabinet, a lifting motor is fixedly installed on the bottom side of the support plate, and the upper and lower ends of the vertical screw are respectively rotatably installed inside the positioning cabinet and on the support plate.

[0010] Furthermore: the chain assembly includes a first sprocket, a first transmission chain, and two second sprockets. The rotor of the lifting motor drives the first sprocket to rotate.

[0011] Furthermore, a first reducer is provided between the lifting motor and the first sprocket, and the lifting motor drives the first sprocket to rotate through the first reducer.

[0030] like Figure 1-7 As shown, the present invention provides a highly stable winding mechanism, including a frame 1, on which a conveyor belt 2 is fixedly installed. Positioning cabinets 3 are provided on both the front and rear sides of the frame 1, and the conveyor belt 2 is positioned between the two positioning cabinets 3.

[0031] The positioning cabinet 3 is fixedly installed with a lifting unit 4. A winding roller 5 is rotatably installed between the lifting units 4 of the two positioning cabinets 3. A roll of material 6 is wound on the winding roller 5. When the winding roller 5 is winding, the bottom side of the roll of material 6 is always against the conveyor belt 2.

[0032] The principle is as follows: the coil material 6 is conveyed on the conveyor belt 2. When it reaches the take-up roller 5, the coil material 6 can be wound up on the take-up roller 5. During winding, the coil material 6 will gradually wrap around the take-up roller 5. After a certain number of turns, the coil material 6 on the take-up roller 5 will gradually become thicker. At this time, the lifting unit 4 drives the take-up roller 5 to gradually rise. It should be noted that the speed at which the lifting unit 4 drives the take-up roller 5 to rise needs to be consistent with the speed at which the coil material 6 becomes thicker, so that the pressure during winding can always be consistent, thereby ensuring the uniform winding of the coil material 6, improving the winding quality, and avoiding the coil material 6 from breaking and being damaged during the winding process.

[0033] Furthermore: the lifting unit 4 includes a lifting motor 41, a chain assembly 42, a lifting platform 43, a roller frame 44, and two vertical screws 45; the lifting motor 41 is fixedly installed inside the positioning cabinet 3, and the two vertical screws 45 are respectively rotatably installed on the left and right sides of the positioning cabinet 3; the chain assembly 42 is installed on the rotor of the lifting motor 41 and the bottom end of the two vertical screws 45, and the lifting motor 41 drives the two vertical screws 45 to rotate synchronously through the chain assembly 42; lifting blocks 7 are fixedly installed on both the left and right sides of the lifting platform 43, lifting... The lowering block 7 has threaded holes 8 formed on it. Vertical screws 45 are screwed into the threaded holes 8 one by one. Roller frames 44 are fixedly installed on the lifting platform 43 one by one. The take-up roller 5 is rotatably installed on the roller frames 44 of the two lifting platforms 43. The chain group 42 allows the two vertical screws 45 to rotate synchronously, and then the lifting motor 41 drives the two lifting blocks 7 to lift synchronously. The lifting platform 43 installed on the two lifting blocks 7 can lift stably in the positioning cabinet 3, thereby ensuring the accurate height positioning of the take-up roller 5.

[0034] Furthermore: a support plate 9 is fixedly installed at the bottom of the positioning cabinet 3, the lifting motor 41 is fixedly installed on the bottom side of the support plate 9, and the upper and lower ends of the vertical screw 45 are respectively rotatably installed inside the positioning cabinet 3 and on the support plate 9; this allows the lifting motor 41 and the chain assembly 42 to be hidden on the bottom side of the support plate 9, which is convenient for actual use.

[0035] Furthermore, the chain assembly 42 includes a first sprocket 421, a first transmission chain 422, and two second sprockets 423. The rotor of the lifting motor 41 drives the first sprocket 421 to rotate. The two second sprockets 423 are respectively fixedly installed at the bottom ends of the two vertical screws 45. The first transmission chain 422 is installed between the first sprocket 421 and the two second sprockets 423. This allows the chain assembly 42 to drive the two vertical screws 45 to rotate synchronously, resulting in higher stability.

[0036] Furthermore, a first reducer 10 is provided between the lifting motor 41 and the first sprocket 421, and the lifting motor 41 drives the first sprocket 421 to rotate through the first reducer 10; this can achieve speed reduction transmission and prevent damage to the lifting motor 41.

[0037] Furthermore, a servo motor 11 and a second reducer 12 are fixedly installed inside one of the lifting platforms 43. The servo motor 11 drives the winding roller 5 to rotate through the second reducer 12. The servo motor 11 drives the winding roller 5 to wind up, realizing automatic winding operation. The setting of the second reducer 12 can prevent damage to the servo motor 11.

[0038] Furthermore: a third sprocket 13 is fixedly installed at the output shaft of the second reducer 12, and a fourth sprocket 14 is fixedly installed at the end of the take-up roller 5 near the servo motor 11. A second transmission chain 15 is installed between the third sprocket 13 and the fourth sprocket 14. The take-up roller 5 can be driven to rotate by the cooperation of the sprocket and the chain, which has higher stability during rotation. The take-up speed can be set according to actual needs, which is convenient for actual use.
