[0025] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] Combined with appendix Figure 1-5 A square lithium iron phosphate battery roll compatible mechanism is used to replace the flange of the feeding part of the square lithium iron phosphate battery slitting machine. It includes a right-side clamping structure 1 and a left-side clamping structure 2 installed on both sides of the slitting machine. The hollow roll 3 of the roll is fixed between the right-side clamping structure 1 and the left-side clamping structure 2, so that the slitting machine drives the roll to rotate to complete the feeding.

[0028] The right-side chuck structure 1 includes a base shaft 11, a shaft disc 12 fixedly mounted on the left end of the base shaft 11, a circular hole inside the shaft disc 12, the left end of the base shaft 11 being inserted into the circular hole on the right end of the shaft disc 12, a threaded hole on the left end face of the base shaft 11, a connecting plate integrally mounted inside the circular hole of the shaft disc 12, and a threaded hole corresponding to the threaded hole of the base shaft 11 on the connecting plate inside the shaft disc 12, the base shaft 11 being fixed to the shaft disc 12 by bolts.

[0029] A screw 13 is provided on the left side of the shaft disk 12. The right end of the screw 13 is also inserted into the hollow circular hole of the shaft disk 12. The screw 13 and the shaft disk 12 are fixedly set relative to each other. The right end of the screw 13 is provided with several evenly distributed grooves. The outer surface of the shaft disk 12 is provided with several evenly distributed threaded holes that penetrate into the circular hole of the peripheral disk 12. The threaded holes on the outer side of the shaft disk 12 are set in positions corresponding to the grooves on the right end of the screw 13. Fixing screws are provided in the threaded holes on the outer side of the shaft disk 12 to fix the screw 13 in the center hole of the shaft disk 12. The screw 13 is concentric with the base shaft 11.

[0030] A bushing 14 is inserted into the screw 13. The bushing 14 has a flange protrusion 141 at one end near the base shaft. Shoulders 15 are provided on both sides of the bushing 14. A right-side chuck 16 is abutted between the two shoulders 15. The right-side chuck 16 is a hollow structure. An inwardly annular engaging protrusion is provided inside the right-side chuck 16. The engaging protrusion is located between the two shoulders 15 and abuts against the two shoulders 15. The two shoulders 15 fix the right-side chuck 16 by engaging.

[0031] Since the right shoulder 15 abuts against the flange protrusion 141, the screw 13 is screwed into the flange protrusion 141 of the bushing 14 with a limit nut 17. The limit nut 17 abuts against the right end face of the flange protrusion 141, thereby providing a locking force on the right side of the right chuck 16 together with the flange protrusion 141.

[0032] An elastic washer 18 abuts against the left end face of the shoulder 15 on the left side. A locking nut 19 is screwed into the leftmost part of the screw 13. By tightening the locking nut 19 to the right, the locking nut 19 squeezes the elastic washer 18, which in turn further squeezes the shoulder 15 on the left side. At this time, the locking nut 19 provides a locking force to the left side of the right chuck 16 by squeezing the shoulder 15 on the left side. Due to the pressure on both sides, the right chuck 16 between the two shoulders is locked. The right chuck 16 is concentric with the base shaft 11 to prevent the drum 3 from shaking after it is installed on the right chuck 16.

[0033] The shaft disc 12 is also provided with abutment screw holes. The abutment screw holes are oriented left and right and several are evenly distributed on the left end face of the shaft disc 12. Abutment bolts 161 are screwed into the abutment screw holes. Abutment nuts are provided on the abutment bolts 161. The abutment nuts are all located on the left end face of the shaft disc 12. The left end face of the abutment bolts 161 abuts against the right end face of the right side chuck. The abutment bolts 161 abut against the right side chuck to prevent the right side chuck from shifting after long-term use, and the abutment nuts prevent the abutment bolts 161 from moving to the right.

[0034] The left-side clamp structure 2 includes a base shaft 21, on which a bushing 22 is fixedly sleeved. The bushing 22 is provided with fixing bolts to fix the bushing 22 to the base shaft 21. The right end of the bushing 22 is a flange, and an extension shaft 23 is fixedly connected to the right end of the bushing 22. The left end of the extension shaft 23 is a flange, and the flange at the right end of the bushing 22 and the flange at the left end of the extension shaft 23 are fixed together by bolts.

[0035] A spline 24 is fixedly provided on the extended shaft 23. The spline 24 starts from the flange face of the extended shaft 23 and has the same shaft length as the extended shaft 23. The left chuck 26 is fixed on the extended shaft 23 and is fixed to the extended shaft 23 by bolts. The extended shaft 23 has threaded holes arranged in different positions in sequence. The position of the left chuck 26 can be changed by bolting the left chuck 26 to the threaded holes at different positions on the extended shaft 23.

[0036] Both the bushing 22 and the extended shaft 23 have lifting screw holes on their flanges. Lifting bolts 25 are installed in the lifting screw holes, and anti-reverse nuts are installed on the lifting bolts 25. The anti-reverse nuts are all located on the right side of the flange faces of the bushing 22 and the extended shaft 23. The right end face of the lifting bolt 25 abuts against the left end face of the left chuck 26, thereby preventing the left chuck 26 from moving after long-term use.

[0037] The left collet 26 is concentric with the base shaft 21 and the extension shaft 23, and the right collet 16 is concentric with the left collet 26.

[0038] Both the right-side chuck 16 and the left-side chuck 26 have a tapered surface on the side facing the drum 3. That is, both the left end face of the right-side chuck 16 and the right end face of the left-side chuck 26 have a tapered surface. The tapered surface can help the right-side chuck 16 and the left-side chuck 26 to align with the drum 3. When the right-side chuck 16 and the left-side chuck 26 are concentric with the drum 3 and rotate synchronously with the drum 3, the drum 3 will not wobble.

[0039] In use, the roll 3 is fitted between the chucks on both sides. The slitting machine moves the right chuck structure 1 and the left chuck structure 2 towards each other, so that the right chuck 16 and the left chuck 26 abut against the roll 3. Due to the inclined conical surfaces on the right chuck 16 and the left chuck 26, the right chuck 16 and the left chuck 26 automatically align. After the right chuck 16 and the left chuck 26 clamp the roll 3, they can cooperate with the slitting machine to unwind and achieve material feeding.

[0040] When used with drums 3 of different lengths, the position of the right-side chuck 16 can be adjusted to accommodate different drum lengths. First, the locking nut 19 is screwed on, then the right-side chuck 16 is adjusted to the appropriate position. Then, the positions of the locking nut 19 and the limit nut 17 are further adjusted to lock the right-side chuck 16. At the same time, the position of the abutment bolt 161 is further changed so that the abutment bolt 161 abuts against the right-side chuck 16 again, so that it can once again play a role in preventing the right-side chuck 16 from slipping.

[0041] The length of the drum 3 can also be changed by altering the position of the threaded hole where the left chuck 26 is fixed to the bolt on the extension shaft 23. After the left chuck 26 is in the appropriate position, the position of the lifting bolt 25 can be readjusted so that it can abut against the left chuck 26 again to prevent it from moving.

[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
