For those skilled in the art, the specific meaning of the above terms in the present patent can be understood according to the specific circumstances.

[0066] Embodiment 1:

[0067] A winding device for insulating film production with automatic roll changing function, as shown in Figures 1-9 The winding device includes a frame 1, a self-changing roll winding part for winding the insulating film, a self-switching driving part for driving the self-changing roll winding part, and a cutter assembly 6 for roll changing and cutting the insulating film. The cutter assembly 6 is fixed to one side of the frame 1 through a fixed shaft 2. The self-changing roll winding part is rotatably connected to one side of the frame 1 through a connecting shaft 9, and is movably mounted to the outer wall of the fixed shaft 2. The driving part is mounted on the outer wall of one side of the frame 1 and is in transmission cooperation with the self-changing roll winding part. The self-changing roll winding part can be driven by the self-switching driving part to wind the insulating film to the full load degree. When the full load degree is reached, the self-changing roll winding part can be driven by the self-switching driving part to change the film roll, and at the same time, the cutter assembly 6 can cut and disconnect the insulating film between the full load film roll and the empty film roll, thereby realizing the automatic roll changing function.

[0068] In order to solve the problem of automatic roll changing; as Figure 1As shown, the self-replacing roll winding part includes two connecting support plates 3 and at least two roll shafts 5 which are detachably installed on opposite sides of the connecting support plates 3, one of the connecting support plates 3 is rotationally connected to the outer wall of the fixed shaft 2, and the other connecting support plate 3 is welded to the outer wall of the connecting shaft 9, and the roll shafts 5 are all rotationally connected to the inner wall of the connecting support plate 3 through the roller shaft 4. Before use, the outer wall of the roll shaft 5 is coated with a layer of glue, and then the roll shaft 5 is installed between the connecting support plates 3. When the two roll shafts 5 are in the position shown in the figure, one of the roll shafts 5 is located in the winding position and is preliminarily bonded and fixed to the insulating film through the glue on the outer wall, and then the insulating film can be wound by rotating. When the roll shaft 5 is fully loaded, the connecting shaft 9 rotates to drive the two roll shafts 5 to rotate, thereby realizing the position switching of the roll shaft 5. At the same time, the cutter assembly 6 cuts the connection of the film roll. After the two roll shafts 5 are switched, the other roll shaft 5 starts to work. At this time, the worker can remove the fully loaded roll shaft 5 and replace it with a new roll shaft 5.

[0069] In order to solve the problem of automation; such as Figures 1-5 As shown, the self-switching driving part includes a transmission member 10, a reversing member 11 and a limiting member 15. The transmission member 10 can provide power for the winding rotation of the roll shaft 5 and the position switching rotation of the roll shaft 5. The reversing member 11 can control the two driving forms of the transmission member 10, i.e., driving the roll shaft 5 to rotate and driving the roll shaft 5 to switch positions. The limiting member 15 can limit the two driving forms, thereby ensuring the intermittent driving of winding and roll replacement under the condition of single power input.

[0070] In order to solve the problem of driving; such as Figure 1 、 2 , 3, the transmission member 10 includes a gear one 7 fixedly installed on the outer wall of the roller shaft 4, a gear two 8 fixedly installed on the outer wall of the connecting shaft 9, an input shaft 12 and a main input gear 17 which can engage with the gear one 7 and the gear two 8. The main input gear 17 is axially slidably arranged on the outer wall of the input shaft 12 through the key-shaped groove 16 arranged on the inner wall of the input shaft 12. When the main input gear 17 engages with the gear one 7, it can drive the roller shaft 4 and the roll shaft 5 thereon to rotate through the gear one 7, thereby realizing the winding of the insulating film. When the winding is fully loaded, the main input gear 17 can move right along the axis of the input shaft 12 to separate from the gear one 7 and engage with the gear two 8, thereby driving the connecting support plate 3 to rotate through the gear two 8 and the connecting shaft 9, realizing the switching of the position. The transmission member 10 further includes an internal thread sleeve 19 which is threadedly connected to the outer wall of the input shaft 12. The internal thread sleeve 19 is rotationally connected with the main input gear 17 through the stepped ring one 18. When the internal thread sleeve 19 rotates relative to the input shaft 12, it can drive the main input gear 17 to move along the axis of the input shaft 12 through the threaded connection with the input shaft 12, thereby switching the engagement state of the main input gear 17.

[0071] In order to solve the meshing state switching problem; as Figure 2 、 4 The reversing piece 11 includes two sets of planetary gear train systems 22 sharing the same sun gear 21; the structure and installation of the planetary gear train system 22 are well known to those skilled in the art, and the present embodiment does not make too much redundant description; the sun gear 21 is axially slidably fitted to the outer wall of the input shaft 12 through the internally threaded sleeve 19, the other side of the sun gear 21 is connected with the stepped ring 25 through the spring 1 24, the rotation of the stepped ring 25 is connected to the inner wall of the internally threaded sleeve 19, one set of the outer ring gear of the planetary gear train system 22 is fixed to the outer wall of the rack 1, the planetary gear of the other set of the planetary gear train system 22 is rotatably connected with the same bracket 23, the bracket 23 is fixed to the top outer wall of the rack 1 through bolts, the outer wall of the internally threaded sleeve 19 is welded with the transmission folded line rod 20, the outer wall of the transmission folded line rod 20 is respectively movably inserted into the planetary gear and the outer ring gear of the two sets of planetary gear train systems 22; the two sets of planetary gear train systems 22 can respectively provide the internally threaded sleeve 19 with rotary driving force through the transmission folded line rod 20, and the two sets of planetary gear train systems 22 share the same sun gear 21, when the sun gear 21 cooperates with the left planetary gear train system 22, the planetary gear train system 22 rotates the internally threaded sleeve 19 and the sun gear 21 at the same direction and different speeds through the revolution of the planetary gear and the transmission folded line rod 20, when the sun gear 21 cooperates with the right planetary gear train system 22, the planetary gear train system 22 rotates the internally threaded sleeve 19 and the sun gear 21 in opposite directions through the rotation of the outer ring gear and the transmission folded line rod 20, thereby achieving the bidirectional movement requirement of the internally threaded sleeve 19 along the input shaft 12.

[0072] In order to solve the meshing state limiting problem, as Figure 2 、 5 The limiting piece 15 includes the T-shaped plate 27 slidably connected to the inner wall of the input shaft 12 and the ball 26 rollingly connected to the outer side of the T-shaped plate 27, the opposite outer wall of the T-shaped plate 27 is buckled with the same spring 2 28, and the input shaft 12 is welded with a limiting ring on the outer side of the meshing position of the sun gear 21 and the two sets of planetary gear train systems 22; when the internally threaded sleeve 19 moves, it can exert an axial force on the sun gear 21 through the spring 1 24, when the axial force is greater than the resistance provided by the ball 26 to the sun gear 21, the ball 26 contracts, the sun gear 21 axially slips, and the meshing position switching is performed, and due to the spherical surface structure of the ball 26, the spherical surface curvature gradually decreases, that is, when the sun gear 21 moves relative to the ball 26, in this process, the resistance of the ball 26 to the sun gear 21 will also gradually decrease, thereby realizing the rapid switching effect of the meshing state of the sun gear 21.

[0073] In order to solve the total drive problem, as Figure 2As shown, the self-switching driving part further comprises a driving source 14 fixedly installed on the top of the rack 1 and a synchronous assembly 13 for synchronously connecting the input shaft 12 and the output shaft of the driving source 14; in the embodiment, the specific types of the synchronous assembly 13 and the driving source 14 are not limited, the driving source 14 can be an electric motor, a pneumatic motor or a hydraulic motor, the synchronous assembly 13 can be a gear pair, a chain wheel transmission member or a belt wheel transmission member, preferably, the driving source 14 is an electric motor and the synchronous assembly 13 is a synchronous belt assembly, the synchronous belt assembly comprises a synchronous belt and a belt wheel, and the installation mode is known to those skilled in the art, which will not be described herein. When the driving source 14 is started, it can drive the input shaft 12 to rotate through the synchronous assembly 13.

[0074] In the embodiment, before use, the outer wall of the winding drum 5 is smeared with a layer of glue, and then the winding drum 5 is installed between the connecting support plates 3; when the two winding drums 5 are in the position shown in the figure, one of the winding drums 5 is located in the winding position and is preliminarily fixedly bonded with the insulating film through the glue on the outer wall; when the driving source 14 is started, it can drive the input shaft 12 to rotate through the synchronous assembly 13, thereby driving the main input gear 17 to rotate; in the state shown in the figure, the sun gear 21 cooperates with the left planetary gear set 22, the inner threaded sleeve 19 rotates at a different speed with the input shaft 12, the inner threaded sleeve 19 pulls the main input gear 17 to move right through the stepped ring 18, until the main input gear 17 disengages from the gear one 7 and engages with the gear two 8; at this time, the main input gear 17 drives the gear two 8 to rotate, the winding drum 5 position is switched, and after the main input gear 17 engages with the gear two 8 for a certain period of time, the spring one 24 is compressed due to the transverse displacement of the inner threaded sleeve 19, and the elastic force of the spring one 24 on the sun gear 21 is greater than the resistance of the ball 26 on the sun gear 21, so that the sun gear 21 quickly slips to the right side and is limited by the right limiting ring and cooperates with the right planetary gear set 22; at this time, the inner threaded sleeve 19 reverses the above direction and drives the main input gear 17 to move left; after the main input gear 17 disengages from the gear two 8, the winding drum 5 position switching is completed at this time, the staff can unload the full winding drum 5 and install a new winding drum 5; as the inner threaded sleeve 19 slides, the main input gear 17 engages with the gear one 7, drives the winding drum 5 in the winding position to rotate, and continues to wind the insulating film; and in a single cycle, the engagement time of the main input gear 17 with the gear one 7 is the winding time of a single winding drum 5.

[0075] Embodiment 2:

[0076] A winding device for insulating film production with automatic winding change function, comprising a rack 1, a connecting support plate 3, a winding drum 5, a driving source 14 and a synchronous assembly 13. Figure 1 、 7As shown, in order to solve the film cutting problem during station switching, this embodiment makes the following improvements on the basis of embodiment 1: the cutter assembly 6 includes a blade 35 slidably connected to the inner wall of the fixed shaft 2 through a T-shaped slide bar 36 and a double-raised cam 38 connected to the outer wall of the connecting shaft 9 by interference fit, and the outer wall of the T-shaped slide bar 36 is provided with a spring three 37.

[0077] In this embodiment, when the reel 5 station is switched to the point where the two reels 5 are in a horizontal plane, the connecting shaft 9 rotates synchronously with the reel 5 station switching, which drives the double-raised cam 38 to rotate. Through the structural limiting effect of the double-raised cam 38, the blade 35 is pushed out, thereby cutting off the connecting film between the two reels 5, ensuring the reliability of the automatic switching and winding of the reel 5.

[0078] Example 3:

[0079] A winding device for insulating film production with automatic roll changing function, such as Figure 1 、 7 As shown, in order to solve the anti-rotation problem in the non-driven state, this embodiment makes the following improvements on the basis of Example 1: the rotation connection between the reel 5 and the connecting support plate 3, and the rotation connection between the connecting support plate 3 and the fixed shaft 2 are both provided with a rotation one-way locking member, and the one-way locking member includes a fixed member connecting member 29 and a movable member connecting member 34, the outer wall of the movable member connecting member 34 is welded with a circular array of pawls 30, the inner wall of the fixed member connecting member 29 is rotatably connected to a limiting claw 33 that can cooperate with the pawl 30 through a torsion shaft 32, and the outer wall of the torsion shaft 32 and the opposite side of the fixed member connecting member 29 are welded with the same torsion spring 31.

[0080] When the reel 5 is wound up and the work station is switched, it rotates and disengages from the drive. If the rotational displacement at this time drives the reel 5 to rotate in the opposite direction by pulling the uncut insulating film, the insulating film that has been wound up on the reel 5 will be detached again, causing the winding to fail. When the reel 5 is in the wound state, the connecting support plate 3 is disengaged from the drive. When the reel 5 is wound up, tension will be generated between it and the insulating film. This tension will drive the connecting support plate 3 to rotate, causing the work station of the reel 5 to be unstable and the winding to fail.

[0081] In this embodiment: by setting a movable part connecting part 34 and a fixed part connecting part 29, the movable part connecting part 34 can be fixed to the roller shaft 4 and the fixed shaft 2, and the fixed part connecting part 29 is fixed to the connecting support plate 3, so that the limiting claw 33 cooperates with the pawl 30 on the outside of the movable part connecting part 34 to realize the one-way rotation and reverse self-locking rotation function of the roller shaft 4 relative to the connecting support plate 3 and the connecting support plate 3 relative to the fixed shaft 2, thereby preventing the abnormal rotation of the reel 5 and the connecting support plate 3 caused by the film tension in the non-driven state, thereby ensuring the safety and reliability of the entire winding and reel changing process.
