The earliest adhesives came from animals and plants. In the 19th century, rubber was the main component of adhesives; and now various polymers are widely used. Lenses are transparent materials with one or more curved surfaces made of optical materials such as glass or polyurethane. They are often used in the fields of optics, photography, or lasers. At present, the molds for making polyurethane lenses usually use two molds (one A mold and one B mold).

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0021] See also Figures 1 to 4 The utility model provides a winding device for processing a special packaging tape for polyurethane optical lenses, comprising two support plates 1 and a winding roller 2 rotatably connected between the two support plates 1. The support plate 1 is connected with a locking mechanism for locking the winding roller 2, and the locking mechanism comprises a cylinder 14 and a positioning plate 18. The cylinder 14 is used to drive the positioning plate 18 to rise and fall. The end of the winding roller 2 is connected with a rotating disk 15, and the rotating disk 15 matches the positioning plate 18. The top of the positioning plate 18 is a friction surface, which can increase the contact friction between the rotating disk 15 and the positioning plate 18, so as to achieve good locking of the rotating disk 15. The winding roller 2 is connected with a pressing mechanism for pressing the tape, and the winding roller 2 is connected with a motor 4 for driving the winding roller 2 to rotate.

[0022] The motor 4 can drive the winding roller 2 to rotate, which is convenient for winding the tape. After winding a proper amount of tape, the motor 4 stops, and the cylinder 14 drives the telescopic rod 19 to extend, so that the positioning pressure plate 18 moves up quickly and presses against the rotating disk 15, thereby achieving the positioning and locking of the rotating disk 15, and then fixing the winding roller 2, achieving the winding of a certain amount of tape, which is convenient for subsequent processing.

[0023] The locking mechanism also includes a vertical slot 16, a leading block 17, a telescopic rod 19, and a cylinder seat 20. The cylinder seat 20 is connected to the support plate 1. The cylinder 14 is fixed to the top of the cylinder seat 20, and the power output end of the cylinder 14 is connected to the telescopic rod 19. The end of the telescopic rod 19 is fixedly connected to the positioning pressure plate 18. The leading block 17 is used to guide the positioning pressure plate 18, and the leading block 17 is connected to the vertical slot 16, and the vertical slot 16 is arranged on the support plate 1.

[0024] The block 17 is fixedly connected to the side of the positioning pressure plate 18, and the block 17 is slidably connected to the vertical groove 16. When the positioning pressure plate 18 moves, the block 17 slides on the vertical groove 16, which can improve the stability of the movement of the positioning pressure plate 18, play a good guiding role, and can be accurately pressed on the rotating disk 15 to avoid misalignment.

[0025] A connecting disk 3 is rotatably connected to the inner side of the support plate 1, and both ends of the winding roller 2 are detachably connected to the two connecting disks 3. The detachable connection is a bolt connection, which is convenient for disassembly and assembly of the winding roller 2. The power output end of the motor 4 is connected to the connecting disk 3, and the other connecting disk 3 is connected to the rotating disk 15.

[0026] The pressing mechanism includes a connecting column 5, a connecting tube 6, an arc-shaped pressure plate 7, a sliding block 23, a spring 24, and an inner cavity 25. The two ends of the connecting column 5 are connected to the arc-shaped pressure plate 7 and the sliding block 23. The arc-shaped pressure plate 7 is attached to the winding roller 2. The inner cavity 25 is arranged in the connecting tube 6. The sliding block 23 is slidably connected to the inner cavity 25. The spring 24 is used to drive the sliding block 23 to move in the direction close to the arc-shaped pressure plate 7. During the process of winding the tape by the winding roller 2, the connecting column 5 and the sliding block 23 move downward, and the spring 24 is gradually compressed, so that the arc-shaped pressure plate 7 is always in close contact with the tape, achieving a good compaction purpose and facilitating subsequent processing. The sliding block 23 plays a good guiding role for the connecting column 5, that is, the arc-shaped pressure plate 7 is stably raised and lowered to prevent skewing and deviation.

[0027] The spring 24 is located in the inner cavity 25 , and both ends of the spring 24 are connected to the sliding block 23 and the connecting tube 6 .

[0028] The support plate 1 is fixed with a fixing plate 8, and the fixing plate 8 is slidably connected with a guide column 13, and the end of the guide column 13 is connected to the arc-shaped pressing plate 7, and the guide column 13 further guides the arc-shaped pressing plate 7. The guide column 13 is provided with a plurality of positioning grooves 21, and the fixing plate 8 is connected with a locking head 22 matching the positioning grooves 21, and the locking head 22 includes a rotary handle and a stud connected to the rotary handle, and the stud is threadedly connected to the fixing plate 8. When the winding roller 2 winds up an appropriate amount of tape and is disassembled, the rotary handle is rotated to connect the end of the stud with the corresponding positioning groove 21, so as to achieve the locking of the guide column 13, and then the arc-shaped pressing plate 7 is limited and fixed, so as to prevent the arc-shaped pressing plate 7 from moving up due to the thrust applied by the spring 24 to the arc-shaped pressing plate 7, so as to facilitate the disassembly and assembly of the winding roller 2.

[0029] The fixed plate 8 is connected with a control mechanism for controlling the opening or closing of the cylinder 2 14, and the control mechanism includes a control switch 10, a base 11, a cylinder 12, and a telescopic rod 1. The cylinder 12 is fixed to the fixed plate 8, and the power output end of the cylinder 12 is connected to the telescopic rod 1, and the end of the telescopic rod 1 is connected to the base 11. The control switch 10 is connected to the top of the base 11, and the arc-shaped pressing plate 7 is connected with a pressing head 9 that matches the control switch 10. When the pressing head 9 presses on the control switch 10, the cylinder 2 14 starts to work, so that the positioning pressing plate 18 is pressed against the rotating disk 15, and the winding roller 2 is locked. At this time, the winding roller 2 reels an appropriate amount of tape, and then the disassembly operation is carried out, and the motor 4 stops. When the new winding roller 2 is installed, the locking head 22 is operated to loosen the arc pressure plate 7, and the compressed spring 24 drives the arc pressure plate 7 to move upward, so that the pressing head 9 is separated from the control switch 10, and the cylinder 2 14 drives the positioning pressure plate 18 to return to the position, so as to loosen the rotating disk 15, and the motor 4 starts to work and drives the winding roller 2 to rotate and perform the winding operation. The cylinder 12 can drive the telescopic rod 1 to extend and retract, which is convenient for the base 11 and the control switch 10 to rise and fall, so that the position of the control switch 10 can be controlled, which is convenient for controlling the amount of tape winding.

[0030] Working principle: Motor 4 drives the winding roller 2 to rotate to realize the winding operation of the tape. As the winding amount increases, the connecting column 5 and the sliding block 23 move down synchronously, the spring 24 is gradually compressed, and the arc pressure plate 7 is always pressed on the tape to achieve good compaction and facilitate subsequent processing. After winding an appropriate amount of tape, the pressing head 9 presses on the control switch 10, and the cylinder 14 starts to work, driving the positioning pressure plate 18 to move up and press against the rotating disk 15 to realize the positioning of the winding roller 2. The motor 4 is in the shutdown state, and then the locking head 22 is used to fix the guide column 13 to achieve the locking of the arc pressure plate 7, which is convenient for the disassembly of the winding roller 2. When the new winding roller 2 is installed, the rotary locking head 22 loosens the guide column 13, and the compressed spring 24 drives the arc pressure plate 7 to move upward, so that the arc pressure plate 7 presses on the tape, and the pressing head 9 is separated from the control switch 10. The cylinder 2 14 drives the positioning pressure plate 18 to return to its original position, so that it is separated from the rotating disk 15, thereby loosening the winding roller 2, and the motor 4 drives the winding roller 2 to rotate to perform the winding operation.
