[0033] Further basis Figure 2 , Figure 3 , Figure 4 and Figure 5The working process of an example of a tape preparation process shown is:

[0034] The cross slot 2 at the side end of the winding roller 1 facilitates the drive connection, and the shaping paper roller 3 is fixed to the surface of the winding roller 1 through the internal thread of the winding roller 1. The shape characteristics of the shaping paper roller 3 are used to specify the shape of the wound tape, thereby changing the style of the formed tape, which is suitable for use in tapes at different positions.

[0035] Further optimization in combination with the above embodiments:

[0036] Further basis Figure 2 , Figure 3 , Figure 4 and Fig.12 The working process of an example of a tape preparation process shown is:

[0037] Through the multiple molding grooves 5 for tape molding on the shaping paper roller 3, the winding tape roller 4 is rolled and formed according to the shape of the molding grooves 5 under the state of being squeezed and fitted. The winding tape roller 4 after winding is evenly provided with grooves of the same shape as the molding grooves 5. After slitting, a tape of a special shape is formed, which is suitable for fitting and gluing at special angles to avoid large creases and gaps.

[0038] Further optimization in combination with the above embodiments:

[0039] Further basis Figure 2 , Figure 3 , Figure 4 and Fig.12 The working process of an example of a tape preparation process shown is:

[0040] By placing the winding roller 1 to be wound on the support platform 9, the winding positioning driver 8 is driven to make the winding driver 6 and the roller tip 7 move inward or outward synchronously, so as to facilitate the clamping and separation of the winding roller 1; the winding driver 6 is connected and driven through the cross slot 2 to provide power for rotation for winding; the center of the winding roller 1 is fixed by the roller tip 7, so as to facilitate stable winding.

[0041] Further optimization in combination with the above embodiments:

[0042] Furthermore, the winding roller 1 is arranged on two support platforms 9 for support, and an assembled bearing seat 10 for rotation is fixed on the support platform 9 by bolts. The two ends of the winding roller 1 are respectively rotatably arranged in the two assembled bearing seats 10, and the assembled bearing seats 10 are fixed to the winding roller 1 by bolts. The two support platforms 9 are respectively fixedly connected to the two ends of the processing base 11 for supporting operation.

[0043] This part is based on Figure 2 , Figure 3 , Figure 4 and Fig.12 The working process of an example of a tape preparation process shown is:

[0044] Through the two assembly bearing seats 10 for rotation on the two support platforms 9, the bearings fixed at both ends of the winding roller 1 are clamped in the two assembly bearing seats 10 and are easy to rotate. The semicircular ring of the bearing seat 10 is assembled by bolts to facilitate the removal and placement of the winding roller 1, and the assembly bearing seat 10 is locked and fixed by bolts.

[0045] Further optimization in combination with the above embodiments:

[0046] Furthermore, two arc-shaped adding drivers 12 for processing drive adding are evenly fixed on the processing base 11, and the arc-shaped adding driver 12 is driven by a gear rack to drive an arc-shaped adding platform 13 for arc-shaped adding. The arc-shaped adding platform 13 is limited and slid in the processing base 11 by an arc-shaped groove.

[0047] This part is based on Figure 5 , Figure 6 , Figure 7 and Figure 8 The working process of an example of a tape preparation process shown is:

[0048] Through the two arc-shaped adding drivers 12 on the processing base 11, the two arc-shaped adding platforms 13 are driven inward to add, and the rolled tape is processed, or retracted into the processing base 11 for convenient storage and shielding.

[0049] Further optimization in combination with the above embodiments:

[0050] Furthermore, the two arc-shaped adding platforms 13 are respectively fixed with a forming extruder 14 for extrusion and a slitter 15 for slitting and dispersing.

[0051] This part is based on Figure 5 , Figure 6 , Fig.10 and Fig.11 The working process of an example of a tape preparation process shown is:

[0052] The two arc-shaped adding drivers 12 are controlled by frequency conversion driving to respectively perform driving control when using the forming extruder 14 for extrusion forming and the slitter 15 for slitting and dispersion, so as to facilitate the adding and adjusting of the processing drive.

[0053] Further optimization in combination with the above embodiments:

[0054] Furthermore, the forming extruder 14 includes two limiting slide frames 16, multiple spring shafts 17, a tightening slide 18 and multiple extrusion convex rollers 19. The two limiting slide frames 16 are evenly fixed on the arc-shaped adding platform 13 on the left, and multiple spring shafts 17 are evenly fixed on the arc-shaped adding platform 13 on the left. The two ends of the tightening slide 18 are respectively limited and slid in the two limiting slide frames 16, and the tightening slide 18 slides on the multiple spring shafts 17. Multiple extrusion convex rollers 19 are rotatably set on the fixed shaft on the tightening slide 18, and the extrusion convex rollers 19 are in contact with the winding tape roller 4.

[0055] This part is based on Figure 5 , Figure 6 , Figure 7 and Figure 8 The working process of an example of a tape preparation process shown is:

[0056] By driving the arc-shaped adding platform 13, the two limiting slide frames 16 are driven with the tightening slide 18 and the multiple extrusion convex rollers 19 toward the winding tape roller 4 until the extrusion convex roller 19 fits and squeezes the winding tape roller 4. By setting the springs on the multiple spring shafts 17, as the tape is continuously wound thicker, the springs on the spring shafts 17 are continuously squeezed, thereby increasing the squeezing force, thereby making the density of the wound tape tighter and the wound tape thicker, while also avoiding continuous squeezing interference and avoiding deviation of the squeezing convex roller 19 and the winding tape roller 4 during the fitting and winding process.

[0057] Further optimization in combination with the above embodiments:

[0058] Furthermore, the slitter 15 includes a slitting drive 20, a plurality of slitting blades 21, a plurality of fixed knife supports 22 and a side locking slide 23. The slitting drive 20 is fixed to the arc-shaped adding platform 13 on the right side through a motor seat. A plurality of fixed knife supports 22 are fixed to the transmission shaft of the slitting drive 20 through internal threads. The slitting blades 21 are fixed to the fixed knife supports 22 through bolts. The transmission shaft of the slitting drive 20 rotates in the side locking slide 23, and the side locking slide 23 is connected to the arc-shaped adding platform 13 on the right side through threaded cooperation.

[0059] This part is based on Fig.12 , Fig. 9 , Fig.10 and Fig.11 The working process of an example of a tape preparation process shown is:

[0060] By driving the arc-shaped adding platform 13 on the right side, the slitting driver 20 brings multiple slitting blades 21, multiple fixed knife supports 22 and side locking slides 23 to add to the winding tape roller 4. By driving the slitting driver 20, the multiple slitting blades 21 and multiple fixed knife supports 22 are rotated, and the slitting blades 21 cut the middle ends of the shaped paper roller 3 and the forming groove 5, thereby evenly dividing the winding tape roller 4 into multiple parts, which is convenient for daily use. The side locking slide 23 is added by rotating the bolt, and then the installation of the multiple fixed knife supports 22 is squeezed and fixed to avoid the slitting blades 21 from being offset. At the same time, according to the size of the knife support, it is replaced in combination with the actual size requirements.

[0061] The shape of the tape prepared through processing is semi-cylindrical and semi-conical, which is practical for daily angled bonding, avoids the generation of unnecessary creases on the tape, and facilitates perfect fitting at special angles.
