[0027] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0028] The automatic roll-changing mechanism of the winding equipment for adhesive tape production comprises a support frame 1, a guide column 3, a driven gear 4, an expansion roller 6, a spring 7, a drive shaft 8, a transmission shaft 9, a driving gear 10 and a guide block 11;

[0029] like Figures 1 to 4 As shown, rotating plates 2 are rotatably connected to both sides of the support frame 1, one of the rotating plates 2 is equidistantly rotatably connected to a guide column 3, a sleeve 5 is slidably connected to the outside of the guide column 3, and a driven gear 4 is fixedly connected to the outside of the sleeve 5, and an air expansion roller 6 is equidistantly rotatably connected to the inside of the other rotating plate 2, and one end of each guide column 3 is fixedly connected to the corresponding air expansion roller 6, a spring 7 is sleeved on the outside of the guide column 3, and the sleeve 5 is elastically connected to the corresponding air expansion roller 6 through the spring 7, a driving shaft 8 is fixedly connected between the centers of the two rotating plates 2, a transmission shaft 9 is rotatably connected to the inside of the support frame 1, and a driving gear 10 is fixedly connected to the outside of the transmission shaft 9, and the driving gear 10 is meshed with an adjacent driven gear 4, a guide block 11 is fixedly connected to one side of the inner wall of the support frame 1, and a slope is provided on one side of the guide block 11;

[0030] The entire automatic roll-changing mechanism is installed on the tape production line and is firmly fixed in the working position by the support frame 1. During the roll-changing process, when a roll of tape is full and reaches the preset diameter, it is necessary to switch to another empty roll of tape to continue winding. At this time, by controlling the rotation of the drive shaft 8, the rotating plate 2 rotates to drive the air expansion rollers 6 to alternate positions, and their corresponding driven gears 4 will gradually separate from the driving gear 10. As the other set of idle air expansion rollers 6 and their related driven gears 4 rotate with the rotating plate 2, under the action of the guide block 11, the driven gear 4 will slide along the inclined surface of the guide block 11, and its corresponding sleeve 5 will squeeze the spring 7 to contract. When the rotating plate 2 of the driven gear 4 rotates to pass the guide block 11, the spring 7 rebounds to allow the driven gear 4 to reset and mesh with the driving gear 10 to continue the winding operation. Automatic roll changing is achieved by alternating between the three air expansion rollers 6.

[0031] like Figures 1 to 4 As shown, the guide block 11 is located directly below the driving gear 10 to ensure that when the driven gear 4 rotates with the rotating plate 2, the driven gear 4 can be accurately guided to slide through the inclined surface.

[0032] like Figures 1 to 4 As shown, the cross section of the guide post 3 is a regular polygon, so as to ensure that the sleeve 5 can slide on the guide post 3 while rotating synchronously with the guide post 3, thereby preventing the sleeve 5 from rotating during the sliding process.

[0033] like Figures 1 to 4As shown, reinforcing rods 12 are fixedly connected at equal intervals between the rotating plates 2 to enhance the structural strength between the rotating plates 2 and improve the stability and durability of the entire roll-changing mechanism.

[0034] like Figures 1 to 4 As shown, the teeth of the driving gear 10 and the driven gear 4 are arranged on opposite sides in an angular shape, so that the driven gear 4 and the driving gear 10 can guide each other when rebounding, promote easier engagement between the gears, and ensure smooth roll changing.

[0035] like Figures 1 to 4 As shown, mounting holes 13 are equidistantly provided on one side of the support frame 1 so as to facilitate the fixed installation of the automatic roll-changing mechanism on the corresponding position of the tape production equipment.

[0036] like Figures 1 to 4 As shown, a reinforcing ring 14 is provided on each opposite side of the rotating plate 2 . The reinforcing ring 14 surrounds the drive shaft 8 and is fixed to the rotating plate 2 to enhance the structural strength and stability of the connection between the drive shaft 8 and the rotating plate 2 .

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
