[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific preferred embodiments.

[0027] In the description of the present invention, it should be understood that the terms "left side", "right side", "upper part", "lower part", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. "First", "second", etc. do not indicate the importance of the components, and therefore cannot be understood as a limitation on the present invention. The specific dimensions used in this embodiment are only for illustrating the technical solution, and do not limit the scope of protection of the present invention.

[0028] like Figure 1 and Figure 2 The embodiment of the present application discloses a winding mechanism of a double-sided tape slitting machine, including a frame 1, a rocker arm 11, a winding roller 12, a servo cylinder 13 and a support seat 2. The winding roller 12 adopts an inflatable shaft. The winding roller 12 includes a first end and a second end distributed along the axial direction. The first end is rotatably connected to the frame 1, and a bearing 121 is installed at the second end. The diameter of the outer ring of the bearing 121 is not greater than the outer diameter of the winding roller 12. A driving unit for driving the winding roller 12 to rotate is installed on the frame 1. The driving unit includes a servo motor 3. The motor shaft of the servo motor 3 is coaxially connected to one end of the winding roller 12.

[0029] like Figure 1 and Figure 2 The swing rod 11 rotates on the side wall of the frame 1 and corresponds to the second end. The swing rod 11 is provided with an arc groove 115 for supporting the outer ring of the bearing 121. The arc groove 115 is provided with two clamping plates 116 symmetrically distributed about the bearing 121. The clamping plates 116 abut against the outer ring of the bearing 121. The two clamping plates 116 limit the axial movement of the bearing 121 and avoid abutting against the roller in the bearing 121 to avoid interfering with the movement of the bearing 121. The bearing 121 supports the winding roller 12 on the one hand, and reduces the resistance of the winding roller 12 on the other hand.

[0030] like Figure 1 and Figure 2The cylinder body of the servo cylinder 13 is hinged to the frame 1, and the driving rod of the servo cylinder 13 is hinged to the swing rod 11. The servo cylinder 13 drives the swing rod 11 to rotate up and down, so that the swing rod 11 drives the arc groove 115 to abut or separate from the bearing 121.

[0031] like Figure 1 and Figure 3 The support seat 2 is located below the winding roller 12. The support seat 2 is provided with an arc-shaped support plate 21, and the axis of the support plate 21 is parallel to the axis of the winding roller 12. Two vertical guide sleeves 22 are provided on the support seat 2, and two guide posts 23 are provided on the bottom surface of the support plate 21. The two guide posts 23 are respectively inserted into the two guide sleeves 22. The guide sleeves 22 are threaded with locking screws 24. The locking screws 24 vertically penetrate into the guide sleeves 22 and abut against the guide posts 23 to fix the guide posts 23 and the guide sleeves 22, thereby fixing the position of the support plate 21.

[0032] like Figure 1 and Figure 3 The servo motor 3 drives the reel 12 to reel, and the diameter of the tape roll gradually increases. When the reel stops reeling, the tape roll is just supported on the support plate 21. The support of the support plate 21 shares the load on the connection position of the first end of the reel 12 and the frame 1, so as to prevent the reel 12 from bending downward. The operator can adjust the position of the support plate 21 according to the final diameter of the tape roll. When adjusting, the operator loosens the locking screw 24, moves the support plate 21 up and down, and tightens the locking screw 24 after adjustment. It is convenient and quick.

[0033] The guide post 23 is provided with a fastening surface 25 that can fit with the end surface of the locking screw 24 ; the fastening surface 25 increases the contact area between the locking screw 24 and the guide post 23 , thereby increasing the stability of the force of the locking screw 24 .

[0034] like Figure 1 and Figure 2 The rocker arm 11 includes a first rod body 111 and a second rod body 112. The first rod body 111 is hinged to the side wall of the frame 1. The piston rod of the servo cylinder 13 is hinged to the first rod body 111. An arc groove 115 is arranged at the end of the second rod body 112. The first rod body 111 and the second rod body 112 overlap at one end thereof, and the first rod body 111 and the second rod body 112 are fixed at the overlapping part by a bolt assembly 113. A waist groove 114 is provided on the first rod body 111 for the bolt assembly 113 to pass through. The waist groove 114 extends along the length direction of the first rod body 111.

[0035] The bolt assembly 113 includes a screw nut, which is threadedly connected to the nut after vertically passing through the waist groove 114 and the second rod body 112 in sequence. The waist groove 114 and the bolt assembly 113 allow the first rod body 111 and the second rod body 112 to move telescopically in the length direction, and adjust the length of the swing rod 11 to ensure that the position of the arc groove 115 can form an accurate support for the bearing 121, which is convenient for on-site debugging.

[0036] The principle of the embodiment of the present application is as follows: the reel 12 adopts an inflatable shaft. When reeling, a paper tube is sleeved on the reel 12, and the paper tube is tightened by the reel 12. The servo motor 3 drives the reel 12 to rotate, and each tape is wound on a different paper tube. When unloading, the servo cylinder 13 drives the swing rod 11 downward, driving the arc groove 115 to separate from the bearing 121. The operator releases the tension of the reel 12 on the paper tube and can withdraw each paper tube from the reel 12. After that, it is only necessary to replace a new paper tube and restore the support of the swing rod 11 on the bearing 121, without the need to repeatedly load and unload the reel 12.

[0037] The utility model also provides a double-sided tape slitting machine including the winding mechanism disclosed in the above embodiment. For the structures of other parts of the double-sided tape slitting machine, please refer to the prior art and will not be described in detail herein.

[0038] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
