Description

Technical Field

[0001] This application relates to the field of damped unwinding devices, and in particular to the unwinding mechanism of a damped adjustable composite instrument. Background Technology

[0002] Composite unwinding refers to the process of bonding two or more materials together through a specific process to form a new composite material.

[0003] Currently, during the extraction of roll materials, because the roll material itself has a certain mass, if the operation is suddenly stopped, the roll material will continue to rotate under the action of inertia, resulting in redundant roll material supply. This will cause the roll material to fall onto the table, which will lead to contamination. Utility Model Content

[0004] To avoid redundant material supply in the roll, this application provides a damped adjustable composite unwinding mechanism.

[0005] The damping adjustable composite instrument unwinding mechanism provided in this application adopts the following technical solution: the damping adjustable composite instrument unwinding mechanism includes a rotating rod, on which two corresponding mounting sleeves are respectively fitted, and on each of the two mounting sleeves, a corresponding first limiting plate and a second limiting plate are fixedly installed. A mounting column is fixedly installed on the rotating rod, and a mounting opening is provided on one side of the mounting column. A damping mechanism is provided in the mounting opening.

[0006] The damping mechanism includes a telescopic sleeve disposed in the mounting port, a spring disposed inside the telescopic sleeve, a bolt head disposed on one side of the telescopic sleeve, a threaded rod fixedly mounted on one end of the bolt head, a threaded hole adapted to the threaded rod being opened at one end of the rotating rod, a first one-way thrust ball bearing disposed on the side of the telescopic sleeve and the bolt head that are close to each other, and a second one-way thrust ball bearing disposed at one end of the spring.

[0007] By adopting the above technical solution, rotating the bolt head causes the threaded rod to rotate within the threaded hole, which in turn moves the telescopic sleeve and compresses the spring. The damping of the rotating rod is achieved through friction caused by the first and second one-way thrust ball bearings on both sides.

[0008] Preferably, a fixing seat is fixedly installed at one end of the mounting column, and a bearing is provided inside the fixing seat.

[0009] By adopting the above technical solution and setting a fixing base, it can be fixedly installed on the machine body, thereby playing an auxiliary role in installation.

[0010] Preferably, one end of the rotating rod is located inside the bearing and extends into the mounting port.

[0011] By adopting the above technical solution, one end of the rotating rod is located inside the bearing and extends into the mounting port, thereby playing an auxiliary role in installation.

[0012] Preferably, the telescopic sleeve is provided with scale lines.

[0013] By adopting the above technical solution, the tension of the spring can be easily adjusted by setting scale lines.

[0014] Preferably, two limiting grooves are symmetrically opened at one end of the mounting column, and corresponding limiting rods are slidably installed in each of the two limiting grooves, and both limiting rods are fixedly installed with the telescopic sleeve.

[0015] By adopting the above technical solution, the movement position of the telescopic sleeve can be guided and limited through the cooperation of the limiting groove and the limiting rod, thereby improving the stability of the telescopic sleeve during movement and further enhancing its convenience and flexibility in use.

[0016] Preferably, both limiting grooves are connected to the installation port, and the length of the limiting groove is greater than the length of the limiting rod.

[0017] By adopting the above technical solution, the length of the limiting groove must be greater than the length of the limiting rod, thus facilitating sliding.

[0018] Preferably, each of the two mounting sleeves has a corresponding mounting hole, and a corresponding positioning bolt is screwed into each of the mounting holes, with one end of each positioning bolt contacting the outer surface of the rotating rod.

[0019] By adopting the above technical solution, the positioning installation of the mounting sleeve can be released by rotating the positioning bolt, and then the limiting installation of the first limiting plate and the second limiting plate can be released. Therefore, the first limiting plate and the second limiting plate can be disassembled and assembled, and the roll material can be replaced easily.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. This application employs a mechanism where, with the cooperation of springs, rotating the bolt head causes the threaded rod to rotate within the threaded hole, moving the telescopic sleeve and compressing the spring. Friction from corresponding first and second one-way thrust ball bearings on both sides achieves damping of the rotating rod. The compression of the spring can be adjusted to change the damping magnitude, with scale markings for easy adjustment. This allows for damping of the coil rotation, reducing redundant coil feeding length and preventing the coil from falling onto the table and causing contamination.

[0022] 2. This application employs a limiting groove and similar mechanism. Through the combined action of the limiting groove and the limiting rod, the movement position of the telescopic sleeve can be guided and limited, thereby improving the stability of the telescopic sleeve during movement. This further enhances the convenience and flexibility of use. By rotating the positioning bolt, the positioning installation of the mounting sleeve can be released, thereby releasing the limiting installation of the first and second limiting plates. Therefore, the first and second limiting plates can be disassembled and installed, facilitating the replacement of the roll material. Attached Figure Description

[0029] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0030] This application discloses an adjustable damping composite instrument unwinding mechanism.

[0031] Reference Figure 1-3 The damping adjustable composite instrument unwinding mechanism includes a rotating rod 1, and two corresponding mounting sleeves 18 are respectively fitted on the rotating rod 1. A first limiting plate 2 and a second limiting plate 3 are fixedly installed on each of the two mounting sleeves 18. A mounting column 4 is fixedly installed on the rotating rod 1. A mounting opening 5 is opened on one side of the mounting column 4. A damping mechanism is set in the mounting opening 5 and a disassembly and assembly mechanism is set on the rotating rod 1.

[0032] The damping mechanism includes a telescopic sleeve 6 installed in the mounting port 5, a spring 14 installed in the telescopic sleeve 6, a bolt head 7 on one side of the telescopic sleeve 6, a threaded rod 8 fixedly installed at one end of the bolt head 7, a threaded hole 9 adapted to the threaded rod 8 at one end of the rotating rod 1, a first one-way thrust ball bearing 12 on the side of the telescopic sleeve 6 and the bolt head 7 that are close to each other, a second one-way thrust ball bearing 13 at one end of the spring 14, a fixed seat 10 fixedly installed at one end of the mounting column 4, a bearing 11 installed in the fixed seat 10, one end of the rotating rod 1 located in the bearing 11 and extending into the mounting port 5, and a scale line 15 on the telescopic sleeve 6.

[0033] Two limiting grooves 17 are symmetrically opened at one end of the mounting column 4. A corresponding limiting rod 16 is slidably installed in each of the two limiting grooves 17. Both limiting rods 16 are fixedly installed with the telescopic sleeve 6. Both limiting grooves 17 are connected to the mounting port 5. The length of the limiting groove 17 is greater than the length of the limiting rod 16.

[0034] In use, rotating the bolt head 7 causes the threaded rod 8 to rotate within the threaded hole 9, which in turn moves the telescopic sleeve 6 and compresses the spring 14. This friction, achieved through the first one-way thrust ball bearing 12 and the second one-way thrust ball bearing 13 on both sides, dampes the rotating rod 1. The compression of the spring 14 can be adjusted to change the damping magnitude. The scale line 15 is used for indication and adjustment. This allows the rotation of the roll material to have a certain degree of damping, thereby reducing the redundant length of the roll material supply and preventing the roll material from falling onto the table and causing contamination.

[0035] Reference Figure 3-5 The disassembly and assembly mechanism includes corresponding mounting holes 19 on two mounting sleeves 18. Each mounting hole 19 is screwed with a corresponding positioning bolt 20, and one end of each positioning bolt 20 is in contact with the outer surface of the rotating rod 1.

[0036] In use, the positioning bolt 20 can be rotated to release the positioning installation of the mounting sleeve 18, thereby releasing the limiting installation of the first limiting plate 2 and the second limiting plate 3. Therefore, the first limiting plate 2 and the second limiting plate 3 can be disassembled and assembled, facilitating the replacement of the roll material.

[0037] The implementation principle of the unwinding mechanism of the adjustable damping composite instrument in this application embodiment is as follows: In use, by rotating the bolt head 7, the threaded rod 8 will rotate in the threaded hole 9, and the telescopic sleeve 6 will move and compress the spring 14. The damping of the rotating rod 1 is achieved by friction through the first one-way thrust ball bearing 12 and the second one-way thrust ball bearing 13 on both sides. The compression of the spring 14 can be adjusted by the threaded rod 8 to change the damping magnitude. The scale line 15 is used for indication and easy adjustment. In this way, the rotation of the roll material can have a certain damping, thereby reducing the redundant length of the roll material supply and preventing the roll material from falling onto the table and causing contamination.

[0038] With the cooperation of the limiting groove 17 and the limiting rod 16, the movement position of the telescopic sleeve 6 can be guided and limited, thereby improving the stability of the telescopic sleeve 6 during movement. This further enhances the convenience and flexibility of use. By rotating the positioning bolt 20, the positioning installation of the mounting sleeve 18 can be released, thereby releasing the limiting installation of the first limiting plate 2 and the second limiting plate 3. Therefore, the first limiting plate 2 and the second limiting plate 3 can be disassembled and assembled, facilitating the replacement of the roll material.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
