[0039] Referring to the attached Figure 1-8 As shown, embodiments of the present application are proposed. The strip roll bottom cylinder unloading, cylinder changing and barrel changing device described in this embodiment includes:

[0040] A frame having two relatively arranged mounting brackets 10;

[0041] A pay-off roll 20, the two ends of which are respectively rotatably installed on the two mounting brackets 10, and the pay-off roll 20 winds a strip-shaped article;

[0042] Two receiving tables 70 are respectively installed on the two mounting brackets 10, and the two receiving tables 70 are respectively located on the front sides of the two ends of the pay-off roll 20. The two ends of the strip roll 140 are respectively placed on the two receiving tables 70;

[0043] The material rack 100 is arranged on the front side of the rack through a translation mechanism 130.

[0044] Two third clamps 80 are respectively installed on two mounting frames 10 through sliding mechanisms. The two third clamps 80 are respectively used for clamping both ends of the strip coiling roll 140 on the material receiving table 70. The sliding mechanism is used to drive the two third clamps 80 to reciprocate along the material receiving table 70.

[0045] Two fourth clamps 90 are respectively rotatably installed on two mounting frames 10 through a roll shifting driving mechanism. The two fourth clamps 90 can respectively swing on the mounting frame 10 on the same side to the front end of the material receiving table 70 on the same side or one side of the material rack 100 under the action of the roll shifting driving mechanism.

[0046] In this embodiment, a clamping opening is provided on the fourth clamp 90. When the fourth clamp 90 rotates to the front end of the material receiving table 70 on the same side under the drive of the roll shifting driving mechanism, the clamping opening of the fourth clamp faces upward.

[0047] Refer to Figure 8 As shown, in this embodiment, an arc-shaped groove is provided at the rear side of the third clamp 80, and the cross-section of the arc-shaped groove is a major arc. A notch 81 is provided at the lower end of the third clamp 80, and the notch 81 communicates with the inside of the arc-shaped groove.

[0048] Refer to the appendix Figure 1 As shown, both ends of the strip coiling roll 140 are respectively placed on two material receiving tables 70 for winding. After the strip coiling roll 140 finishes winding, after the cutting knife assembly 50 cuts off the film, the roll shifting driving mechanism drives the third clamp 80 on the same side to rotate upward to the front end of the material receiving table 70 on the same side. At this time, the two third clamps 80 clamp both ends of the strip coiling roll 140 on the material receiving table 70. The sliding mechanism drives the two third clamps 80 to drive the strip coiling roll 140 to move forward along the material receiving table 70 and move out of the material receiving table 70. The two third clamps 80 release the clamping of the strip coiling roll 140, and the strip coiling roll 140 falls from the material receiving table 70 into the clamping opening of the fourth clamp 90, as Figure 2 ;

[0049] Refer to the appendix Figure 3 As shown, when the roll shifting driving mechanism drives the fourth clamp 90 to rotate downward to one side of the material rack 10, at this time, the clamping opening of the fourth clamp faces upward. The fourth clamp 90 continues to rotate downward to place the strip coiling roll 140 on the fourth clamp 90 on the material rack, completing the unloading of the strip coiling roll 140.

[0050] In order to enable the strip coiling roll 140 to be stably wound on the material receiving table 70, a groove is further provided on the material receiving table 70, and the strip coiling roll 140 is placed in the groove for winding.

[0051] In this embodiment, it further includes a clamping mechanism 120. The clamping mechanism 120 is arranged at one end of the rack, and the translation mechanism 130 is used to drive the rack to move horizontally in front of the machine frame to approach or move away from the clamping mechanism 120.

[0052] Such as Figure 4 , when the wound roll 140 is unloaded onto the rack 100 by two fourth clamps 90, both ends of the roll 140 extend beyond both ends of the rack 100, that is, the bottom cylinder wound on the roll 140 is placed on the rack 100. The clamping mechanism 120 clamps one end of the roll 140, and the translation mechanism 130 drives the rack 100 to move away from the clamping mechanism 120. The rack 100 drives the bottom cylinder placed on it to move accordingly until the bottom cylinder moves out of the roll 140, and then the rack 100 stops moving. Only need to manually remove the bottom cylinder wound with the film on the rack 100, and then place the bottom cylinder without wound film on the rack 100. The translation mechanism 130 drives the rack 100 to move towards the clamping mechanism 120, which is more convenient to operate and does not require manual removal and installation of the bottom cylinder;

[0053] Such as Figure 6 As shown, the translation mechanism 130 drives the rack 100 to move towards the clamping mechanism 120, so that the bottom cylinder without wound film on the rack 100 moves accordingly and is sleeved on the roll 140 until the bottom cylinder without wound film moves to a preset position with the rack 100, and then the rack 100 stops moving. The clamping mechanism 120 releases the roll 140 and waits for winding.

[0054] The roll 140 is an air shaft. After the bottom cylinder without wound film is sleeved on the roll 140, the roll 140 is inflated to make the bottom cylinder tightly sleeved on the roll 140; after the wound roll 140 is placed on the rack 100, the roll 140 is depressurized to relax the bottom cylinder so that the bottom cylinder can move synchronously with the rack 100.

[0055] Based on the above content, this application further includes:

[0056] Two first clamps 30 are respectively installed on two mounting brackets 10 through a vertical driving mechanism 40 and are respectively located above both ends of the unwinding roller 20;

[0057] A cutter assembly 50 is installed on the machine frame through a rotary driving mechanism. The rotary driving mechanism is used to drive the cutter assembly 50 to rotate around the unwinding roller 20;

[0058] Two second clamps 60 are installed on the cutter assembly 50 and are located at both ends of the unwinding roller 20;

[0059] Two fifth jigs 110, and the two fifth jigs 110 are respectively mounted on the two mounting brackets 10 through swing drive mechanisms, and the two fifth jigs 110 are respectively located on one side of the two fourth jigs 90 away from each other;

[0060] The two vertical drive mechanisms 40 are respectively mounted on the mounting bracket 10 through horizontal movement mechanisms, and the horizontal movement mechanisms are used to drive the vertical drive mechanisms 40 to drive the first jig 30 to move reciprocally between the front side of the material receiving table 70 and above the unwinding roller 20.

[0061] Wherein, clamping openings are provided on the first jig 30 and the second jig 60, the clamping opening of the first jig 30 faces forward, and when the cutting tool assembly 50 rotates above the unwinding roller 20, the clamping openings of the two second jigs 60 face upward.

[0062] After the bottom cylinder of the unreeled film is sleeved on the winding roller 140 and placed on the material rack 100 waiting for winding, when the roller transfer drive mechanism drives the fourth jig 90 on the same side to rotate upward to one side of the material rack 10, at this time the clamping opening of the fourth jig 90 faces upward and clamps the winding roller 140 in its clamping opening, and the fourth jig 90 continues to rotate upward to the front end of the material receiving table 70 on the same side. At this time, both ends of the winding roller 140 are distributed at the front ends of the two material receiving tables 70 at this time, as Figure 6 shown.

[0063] Figure 6 In, the swing drive mechanism drives the two fifth jigs 110 to swing upward from the bottom until the fifth jigs 110 swing to the front side of the material receiving table 70, the vertical drive mechanism 40 drives the two first jigs 30 to descend, and the fifth jigs 110 continue to swing upward and drive the winding roller 140 to continue to rise until it is flush with the two first jigs 30 to as Figure 7 shown in;

[0064] Figure 7 In, the horizontal movement mechanism drives the first jig 30 to move forward so that the first jig 30 clamps the winding roller 140, the vertical drive mechanism 40 drives the first jig 30 to drive the winding roller 140 to move upward away from the fifth jig 110, and the horizontal movement mechanism then drives the two first jigs 30 to drive the winding roller 140 to move above the unwinding roller 20 to as Figure 1 shown in;

[0065] Figure 1In the process, after the cutter assembly 50 is driven by the rotary drive mechanism to rotate to the top of the unwinding roller 20 with the unwinding roller 20 as the axis, the two vertical drive mechanisms 40 drive the two first clamps 30 to descend until the two first clamps 30 and the two second clamps 60 are distributed at the same height, thereby placing the tape roll 140 on the second clamp 60, and the cutter assembly 50 cuts the film, and the film is rewound on the tape roll 140. After the previous tape roll 140 that has completed winding is moved out of the receiving platform 70, the cutter assembly 50 continues to rotate forward, and the second clamp 60 drives the two ends of the tape roll 140 to rotate forward and pass one side of the receiving platform 70. The tape roll 140 on the second clamp 60 is placed on the receiving platform 70, thereby placing the tape roll 140 on the receiving platform 70 for winding, thereby realizing continuous roll replacement and unloading of the tape rolls.

[0066] In this embodiment, the cutter assembly 50 is distributed between the two receiving platforms 70 so that the cutter assembly 50 can rotate between the two receiving platforms 70 with the unwinding roller 20 as the axis, and can place both ends of the second belt winding roller 140 on the receiving platform 70.

[0067] In order to ensure smooth transfer of the tape roll 140 between the first clamp 30 , the second clamp 60 and the fourth clamp 90 , the two first clamps 30 are distributed on both sides of the two fourth clamps 90 close to each other, and the two second clamps 60 are distributed on both sides of the two receiving tables 70 away from each other.

[0068] The fifth clamp 110 is provided with a clamping groove, and when the fifth clamp 110 swings to the front side of the material receiving platform 70 and is flush with the height of the first clamp 30, the clamping grooves on the fifth clamp 110 are all facing upwards, so that when the fifth clamp 110 swings to the front side of the material receiving platform 70, it can directly drive the belt roll 140 to swing upward; and when the fifth clamp 110 swings to be flush with the height of the first clamp 30, the clamping grooves of the fifth clamp 110 are facing upwards, and the vertical drive mechanism 40 drives the two first clamps 30 to move upwards away from the two fifth clamps 110.

[0069] In this embodiment, the first clamp 30 and the second clamp 60 are provided with clamping openings, and the clamping opening of the first clamp 30 faces forward. When the cutter assembly 50 rotates to above the unwinding roller 20, the clamping openings of the two second clamps 60 face upward.

[0070] When the first clamp 30 faces forward, the second clamp 60 rotates with the cutter assembly 50 to drive the second tape roll 140 to rotate and separate from the first clamp 30;

[0071] When the clamping openings of the two second clamps 60 face upward, the first clamp 30 is lowered to place the second belt roll 140 in the second clamps 60 .

[0072] The structures and connection relationships of the rotation drive mechanism, the roller moving drive mechanism, the swing drive mechanism, and the horizontal moving mechanism belong to the commonly used technologies in the art. In this application, the specific structures and connection relationships of the rotation drive mechanism, the roller moving drive mechanism, the sliding mechanism, and the swing drive mechanism are not specifically described, as long as the above work can be satisfied.
