Description

Technical Field

[0001] This utility model relates to the field of roll-to-roll machine technology, specifically to a paper feeding assembly for a sleeve capacitor core roll-to-roll machine. Background Technology

[0002] Capacitor bushings are composite insulating materials that use oil paper and adhesive paper as the main insulation and capacitor voltage equalizing plates to evenly distribute the radial and axial electric fields. When manufacturing capacitor bushings, the paper feeding assembly on the roll-to-roll machine is required to assist in the processing.

[0003] However, while the existing paper feeding assembly for the sleeve capacitor core winding machine can place paper well, it often involves directly inserting the paper roller onto the placement roller. This method does not provide adequate internal support for the paper roller's inner wall. Furthermore, when placing paper rollers of different lengths, the synchronous adjustment of the inner support length is not high. As the paper decreases, the paper roller will wobble and bump against the placement roller under centrifugal force after being directly inserted into the placement roller, affecting the stability of paper conveying.

[0004] Therefore, in view of this, we studied and improved the existing structure to address its shortcomings, and proposed a paper feeding assembly for a sleeve capacitor core winding machine. Utility Model Content

[0005] The purpose of this utility model is to provide a paper feeding assembly for a sleeve capacitor core winding machine, so as to solve the problems mentioned in the background art, which often involve directly inserting the paper roller onto the placing roller for placement, resulting in poor internal support effect on the inner wall of the paper roller, and poor synchronous adjustment of the internal support length of the paper roller when placing paper rollers of different lengths.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a paper feeding assembly for a sleeve capacitor core winding machine, comprising a winding machine body, a connecting frame detachably connected to the outer wall of the winding machine body, a rotating seat rotatably connected to the inner side wall of the connecting frame, an installation plate fixedly connected to the outer wall of the rotating seat, a first servo motor fixedly connected to the bottom of the installation plate, a drive gear rotatably connected to the inner wall of the installation plate fixedly connected to the output end of the first servo motor, a connecting gear rotatably connected to the inner wall of the installation plate meshing with the outer wall of the drive gear, a sliding column slidably connected to the outer wall of the connecting gear, a connecting block slidably connected to the inner wall of the installation plate fixedly connected to the outer wall of the sliding column, a positioning rod fixedly connected to the outer wall of the connecting block, an electric push rod disposed inside the positioning rod, an adjusting rod fixedly connected to one end of the electric push rod, a sleeve capacitor paper roller placed on the surface of the installation plate adhering to the outer wall of the positioning rod, and sleeve capacitor paper being wound up on the outer wall of the sleeve capacitor paper roller.

[0007] Furthermore, a second servo motor is fixedly connected to the outer wall of the connecting frame, and a threaded rod that is rotatably connected to the output end of the second servo motor is fixedly connected to the outer wall of the connecting frame. A threaded slide rod that is slidably connected to the outer wall of the connecting frame is threadedly connected to the outer wall of the threaded rod. A fixing groove is provided at the connection between the outer wall of the connecting frame and the threaded slide rod. A connecting column is slidably connected to the outer wall of the threaded slide rod. A connecting groove is provided at the connection between the outer wall of the threaded slide rod and the connecting column. A rotating rod that is rotatably connected to the outer wall of the connecting frame is fixedly connected to the outer wall of the connecting column.

[0008] Furthermore, the connection between the outer wall of the connecting gear and the sliding column is provided with an inclined groove, the connection between the inner wall of the mounting plate and the connecting block is provided with a sliding groove, and the connection between the outer wall of the mounting plate and the connecting block is provided with a limiting groove.

[0009] Furthermore, the inclined groove is formed in a ring on the surface of the connecting gear, and the inclined groove and the sliding column are configured in a one-to-one correspondence.

[0010] Furthermore, the sliding column forms a sliding structure with the inclined groove through the driving gear and the connecting gear, and the connecting block forms a sliding structure with the limiting groove through the sliding column and the inclined groove. The connecting block and the positioning rod are arranged in a one-to-one correspondence.

[0011] Furthermore, the adjusting rod forms a telescopic structure with the positioning rod via an electric push rod. The outer contours of both the adjusting rod and the positioning rod are cylindrical. There are four sets of both the adjusting rod and the positioning rod, and the positions of the four sets of the adjusting rod and the positioning rod are equidistantly distributed about the central axis of the sleeve capacitor paper roller.

[0012] Furthermore, the threaded slide bar forms a sliding structure between the threaded rod and the fixed groove.

[0013] Furthermore, the rotating rod forms a rotating structure with the connecting frame through the connecting column and the connecting groove. The rotation center of the rotating rod coincides with the rotation center of the rotating seat. The rotation center of the rotating rod is fixedly connected to the rotation center of the rotating seat through a rotating shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the setting of the positioning rod, improves the stability of the fit between the paper roller and the mounting plate when the paper core of the sleeve capacitor is fed through the roll-to-roll machine. This prevents the paper roller from being directly inserted into the placement roller, which would cause the paper roller to shake during subsequent rotation due to centrifugal force. After the paper roller is placed on the mounting plate, the first servo motor is turned on, and the rotation of the drive gear drives the connecting gear to rotate. The rotation of the connecting gear drives the sliding column to slide along the inner wall of the inclined groove. The sliding of the sliding column drives the connecting block to slide along the inner wall of the sliding groove and the limiting groove. This achieves the effect of driving the positioning rod to move along the edge distance of the center of the mounting plate, thereby improving the stability of the paper roller after placement and use.

[0016] 2. By setting an adjusting rod, when it is necessary to place and install paper rollers of different lengths, in order to improve the fitting effect between the positioning rod and paper rollers of different lengths, the electric push rod can be opened according to the specific length of the paper roller, which will drive the adjusting rod to extend and retract along the end of the positioning rod, thereby increasing the overall usable length of the positioning rod and playing the role of adjusting and fitting paper rollers of different lengths.

[0017] 3. By setting up a rotating rod, this utility model allows for improved adjustment of paper conveying states when the paper is processed using the auxiliary sleeve capacitor core of the roll-to-roll machine. The second servo motor can be activated, and the rotation of the threaded rod drives the threaded slide bar to slide along the inner wall of the fixed groove. The sliding of the threaded slide bar causes the connecting column to slide along the inner wall of the connecting groove. The sliding of the connecting column causes the rotating rod to rotate along the outer wall of the connecting frame. The rotation of the rotating rod causes the rotating seat to rotate synchronously, achieving convenient adjustment of the paper conveying state. Attached Figure Description

A sleeve capacitor paper roller 17, which is placed on the surface of the mounting plate 4, is attached to the outer wall of the positioning rod 12. A sleeve capacitor paper 18 is wound up on the outer wall of the sleeve capacitor paper roller 17.

[0027] Furthermore, a slanted groove 9 is provided at the connection between the outer wall of the connecting gear 7 and the sliding column 8, a sliding groove 10 is provided at the connection between the inner wall of the mounting plate 4 and the connecting block 11, and a limiting groove 13 is provided at the connection between the outer wall of the mounting plate 4 and the connecting block 11. This facilitates the effect of driving the connecting block 11 to slide at the center distance through the opening of the slanted groove 9 and the sliding groove 10.

[0028] Furthermore, the inclined groove 9 is formed in a ring on the surface of the connecting gear 7. The inclined groove 9 and the sliding column 8 are set in a one-to-one correspondence. This arrangement of the inclined groove 9 forming a ring on the surface of the connecting gear 7 is conducive to achieving the effect of driving the four sets of positioning rods 12 to slide synchronously.

[0029] Furthermore, the sliding column 8 forms a sliding structure with the inclined groove 9 through the driving gear 6 and the connecting gear 7. The connecting block 11 forms a sliding structure with the limiting groove 13 through the sliding column 8 and the inclined groove 9.

Through the connection of the connecting gear 7, the sliding column 8 is driven to slide along the inner wall of the inclined groove 9, which plays the role of driving the positioning rod 12 to slide conveniently, and improving the stability of the paper roller after placement and bonding.

[0030] Furthermore, the adjusting rod 15 forms a telescopic structure with the positioning rod 12 via the electric push rod 14. The outer contours of both the adjusting rod 15 and the positioning rod 12 are cylindrical. There are four sets of adjusting rods 15 and positioning rods 12. The positions of the four sets of adjusting rods 15 and positioning rods 12 are equidistant from the central axis of the sleeve capacitor paper roller 17, which is beneficial for driving the electric push rod 14 to drive the adjusting rod 15 to telescopically move along the end of the positioning rod 12, thereby playing the role of adjusting and fitting paper rollers of different lengths.

[0031] Example 2: Figure 1 , Figure 2 and Figure 6 As shown, the paper feeding assembly for the sleeve capacitor core winding machine proposed in this utility model, compared with Embodiment 1, is another embodiment of this utility model. A second servo motor 19 is fixedly connected to the outer wall of the connecting frame 2. A threaded rod 20, rotatably connected to the outer wall of the connecting frame 2, is fixedly connected to the output end of the second servo motor 19. A threaded slide rod 21, slidably connected to the outer wall of the connecting frame 2, is threadedly connected to the outer wall of the threaded rod 20. A fixing groove 22 is provided at the connection point between the outer wall of the connecting frame 2 and the threaded slide rod 21. A connecting post 23 is slidably connected to the outer wall of the threaded slide rod 21. A connecting groove 24 is provided at the connection point between the outer wall of the threaded slide rod 21 and the connecting post 23. A rotating rod 16 is fixedly connected to the outer wall of the connecting frame 2. During operation, by setting the rotating rod 16, it is beneficial to improve the adjustment effect of different paper conveying states when processing through the auxiliary sleeve capacitor core of the roll-to-roll machine. The second servo motor 19 can be turned on, and the rotation of the threaded rod 20 drives the threaded slide rod 21 to slide along the inner wall of the fixed groove 22. The sliding of the threaded slide rod 21 drives the connecting column 23 to slide along the inner wall of the connecting groove 24. The sliding of the connecting column 23 drives the rotating rod 16 to rotate along the outer wall of the connecting frame 2. The rotation of the rotating rod 16 drives the rotating seat 3 to rotate synchronously, so as to achieve the effect of convenient adjustment of the paper conveying state.

[0032] Furthermore, the threaded slide bar 21 forms a sliding structure between the threaded rod 20 and the fixed groove 22, which facilitates the rotation of the threaded rod 20 and drives the threaded slide bar 21 to slide along the inner wall of the fixed groove 22, thereby enabling the rotating rod 16 to rotate conveniently.

[0033] Furthermore, the rotating rod 16 forms a rotating structure with the connecting frame 2 through the connecting column 23 and the connecting groove 24. The rotation center of the rotating rod 16 coincides with the rotation center of the rotating seat 3. The rotation center of the rotating rod 16 is fixedly connected to the rotation center of the rotating seat 3 through a rotating shaft. This facilitates the sliding of the connecting column 23 along the inner wall of the connecting groove 24, driving the rotating rod 16 to rotate along the outer wall of the connecting frame 2, thereby achieving the effect of convenient adjustment of the paper conveying status.

[0034] Working principle: When using the paper feeding assembly of the sleeve capacitor core roll-up machine, firstly, when the sleeve capacitor core is fed through the roll-up machine, in order to improve the stability of the fit between the paper roller and the mounting plate 4 and prevent the paper roller from being directly inserted into the placement roller, which would cause the paper roller to shake during subsequent rotation due to centrifugal force, the paper roller can be placed on the mounting plate 4. Then, the first servo motor 5 is turned on, and the rotation of the drive gear 6 drives the connecting gear 7 to rotate. The rotation of the connecting gear 7 drives the sliding column 8 to slide along the inner wall of the inclined groove 9. The sliding of the sliding column 8 drives the connecting block 11 to slide along the inner wall of the sliding groove 10 and the limiting groove 13, thereby driving the positioning rod 12 to move along the edge distance of the center of the mounting plate 4, which improves the stability of the paper roller after placement.

[0035] Secondly, when it is necessary to place and install paper rollers of different lengths, in order to improve the fit between the positioning rod 12 and paper rollers of different lengths, the electric push rod 14 can be opened according to the length of the specific paper roller, and the adjusting rod 15 can be moved along the end of the positioning rod 12 to increase the overall length of the positioning rod 12, thereby achieving the function of adjusting and fitting paper rollers of different lengths.

[0036] Finally, when processing the auxiliary sleeve capacitor core of the roll-to-roll machine, in order to improve the adjustment effect of different paper conveying states, the second servo motor 19 can be turned on. The rotation of the threaded rod 20 drives the threaded slide rod 21 to slide along the inner wall of the fixed groove 22. The sliding of the threaded slide rod 21 drives the connecting column 23 to slide along the inner wall of the connecting groove 24. The sliding of the connecting column 23 drives the rotating rod 16 to rotate along the outer wall of the connecting frame 2. The rotation of the rotating rod 16 drives the rotating seat 3 to rotate synchronously, so as to achieve the effect of convenient adjustment of the paper conveying state.
