The reel changing assembly is used for realizing switching between a first material belt a and a second material belt, namely, when the unreeling of the first material belt a on the first unreeling mechanism 11 is completed, the reel changing assembly switches the second material belt unreeled and output by the second unreeling mechanism 12 to be conveyed downstream, and when the unreeling of the second material belt of the second unreeling mechanism 12 is completed, the reel changing assembly switches the first material belt a unreeled and output by the first unreeling mechanism 11 to be conveyed downstream.

The first adsorption mechanism 22 includes a first adsorption seat 221, and the second adsorption mechanism 23 includes a second adsorption seat 231. The first adsorption seat 221 and the second adsorption seat 231 are arranged along a first direction, so that the first material belt a unwound and output by the first unwinding mechanism 11 or the second material belt unwound and output by the second unwinding mechanism 12 passes through a space between the first adsorption seat 221 and the second adsorption seat 231 and is conveyed downstream. The first suction seat 221 and the second suction seat 231 are configured such that at least one thereof is movable toward or away from each other in a first direction with respect to the other, thereby clamping the first strip a or the second strip passing between the first suction seat 221 and the second suction seat 231 when the first suction seat 221 and the second suction seat 231 are moved toward each other.

The side of the first suction holder 221 facing the second suction holder 231 has first and

The first adsorption area 2211 is used for adsorbing the first material belt a, and the second adsorption area 2212 is used for adsorbing the second material belt. The first adsorption seat 221 is further configured to be movable in a second direction perpendicular to the first direction, and during the movement of the first adsorption seat 221 in the second direction, the first adsorption area 2211 and the second adsorption area 2212 may be alternately aligned with the second adsorption seat 231 in the first direction. When the first adsorption areas 2211 are aligned with the second adsorption seats 231 in the first direction, the first adsorption seats 221 and the second adsorption seats 231 approach each other in the first direction to clamp the first material belt a passing between the first adsorption areas 2211 and the second adsorption seats 231; when the second adsorption areas 2212 are aligned with the second adsorption seats 231 in the first direction, the first adsorption seats 221 and the second adsorption seats 231 approach each other in the first direction to clamp the second material tape passing between the second adsorption areas 2212 and the second adsorption seats 231.

When the roll of the first unwinding mechanism 11 is used up and needs to be changed, first, the first suction seat 221 and the second suction seat 231 approach each other to clamp the first tape a, the cutting mechanism 24 cuts the first tape a, and the second suction seat 231 sucks the cut first tape a. Then, the first suction seat 221 and the second suction seat 231 are separated from each other, the first suction seat 221 moves along the second direction until the second suction area 2212 is aligned with the second suction seat 231 in the first direction, and the first suction seat 221 and the second suction seat 231 approach each other, so as to adhere the cut first material tape a sucked by the second suction seat 231 to the starting end of the second material tape sucked by the second suction area 2212. Finally, the second adsorption area 2212 of the first adsorption seat 221 releases adsorption of the second material strip, the second adsorption seat 231 releases adsorption of the cut first material strip a, and the first adsorption seat 221 and the second adsorption seat 231 are away from each other, so that the second material strip passes through the space between the first adsorption seat 221 and the second adsorption seat 231 and is conveyed downstream along with the cut first material strip a, that is, reel change is realized.

It should be noted that the first material tape a and the second material tape may be adhesive tapes, so that the starting end of the first material tape a may be adhered to the cut end of the second material tape, or the starting end of the second material tape may be adhered to the cut end of the first material tape a during the roll changing process. Of course, in other embodiments, the first and second strips of material a and b may not be adhesive tape. At this time, the starting end of the first material belt a on the material roll is pasted with a double-sided adhesive tape, so that the starting end of the first material belt a is conveniently adhered with the cut end of the second material belt in the process of changing the roll. The double-sided adhesive tape is adhered to the starting end of the second material belt on the material roll, so that the starting end of the second material belt is adhered to the cut end of the first material belt a in the process of changing the roll.

It should be noted that, specifically, in the embodiment shown in fig. 1, the first direction is an up-down direction, and the second direction is a direction perpendicular to the paper surface.

In the embodiment of the present invention, the first adsorption seat 221 includes a first position and a second position in the process of moving along the second direction.

As described above, when the roll of the first unwinding mechanism 11 runs out and a roll change is required, the first suction seat 221 and the second suction seat 231 approach each other to clamp the first tape a between the first suction area 2211 of the first suction seat 221 and the second suction seat 231, the cutting unit cuts the first tape a, and the second suction seat 231 sucks the cut first tape a. Then, the first suction seat 221 and the second suction seat 231 are separated from each other, and the first suction seat 221 moves in the second direction until the second suction area 2212 is aligned with the second suction seat 231 in the first direction. Then, the second suction seat 231 and the first suction seat 221 approach each other to stick the cut first tape a sucked by the second suction seat 231 to the beginning end of the second tape sucked by the second suction area 2212. Finally, the second adsorption area 2212 of the first adsorption seat 221 releases adsorption of the second material strip, the second adsorption seat 231 releases adsorption of the cut first material strip a, and the first adsorption seat 221 and the second adsorption seat 231 are away from each other, so that the second material strip can pass through between the first adsorption seat 221 and the second adsorption seat 231 following the cut first material strip a and then be conveyed downstream. It is understood that the second suction seat 231 may suck the first material strip a before the cutting mechanism 24 cuts the first material strip a, or after the cutting mechanism 24 cuts the first material strip a, which is not limited herein.

When the first suction seat 221 is located at the second position, the second suction seat 231 is aligned with the second suction area 2212 in the first direction, the cutting mechanism 24 is configured to cut the second material strip clamped by the first suction seat 221 and the second suction seat 231 approaching each other along the first direction, and the second suction seat 231 can suck the cut second material strip. As described above, when the roll of the second unwinding mechanism 12 is used up and the roll change is required, first, the first suction seat 221 and the second suction seat 231 approach each other to clamp the second tape between the second suction area 2212 of the first suction seat 221 and the second suction seat 231, the cutting unit cuts the second tape, and the second suction seat 231 sucks the cut second tape. Then, the first suction seat 221 and the second suction seat 231 are separated from each other, and the first suction seat 221 is moved in the second direction until the first suction area 2211 is aligned with the second suction seat 231 in the first direction. Then, the second suction holder 231 and the first suction holder 221 approach each other to stick the cut second tape sucked by the second suction holder 231 to the leading end of the first tape a sucked by the first suction area 2211. Finally, the first adsorption area 2211 of the first adsorption seat 221 releases adsorption of the first material strip a, the second adsorption seat 231 releases adsorption of the cut second material strip, and the first adsorption seat 221 and the second adsorption seat 231 are away from each other, so that the first material strip a can pass through between the first adsorption seat 221 and the second adsorption seat 231 following the cut second material strip and then be conveyed downstream. It is understood that the second material strip may be sucked by the second suction seat 231 before the cutting mechanism 24 cuts the second material strip, or after the cutting mechanism 24 cuts the second material strip, which is not limited herein.

So, when the second material strap needs to be compressed, first, the first belt pressing driving member 242 drives the first moving seat 243 to move close to the second adsorption area 2212 along the first direction, so as to drive the first belt pressing block to contact with the second material strap, and further compress the second material strap in the second adsorption area 2212. Then, the first tape pressing driving member 242 continues to drive the first moving seat 243 to move close to the second absorbing area 2212 along the first direction, so as to compress the first elastic buffer 244, and further drive the first cutting knife 26 to continue to move towards the second tape until the first cutting knife 26 cuts the start end of the second tape. Alternatively, the first resilient buffer 244 may be a spring. The first press block may be mounted to the first moving base 243 through a guide rod and a guide sleeve, so that the first press block is movable in a first direction with respect to the first moving base 243 by the guide of the guide rod and the guide sleeve.

The second belt pressing mechanism 25 further includes a second movable base and a second elastic buffer. The second movable seat is connected to the driving end of the second press belt driving piece, and the second press belt driving piece is used for driving the second movable seat to move back and forth along the first direction. The second press belt block is movably connected to the second moving seat along the first direction, and the second elastic buffer piece is arranged between the second moving seat and the second press belt block so as to provide pretightening force for enabling the second press belt block to have a movement trend away from the second moving seat along the first direction. The second strip pressing block can press the first strip a to the first absorbing area 2211 in the process of moving along the first direction along with the second moving seat, and meanwhile, the second elastic buffer piece can be compressed to play a buffering role.

The second cutting blade 27 is mounted to the second moving base of the second belt pressing mechanism 25 to move in synchronization with the second moving base in the first direction. Therefore, when the first material strap a needs to be compressed, firstly, the second press belt driving member drives the second moving seat to move close to the first absorbing area 2211 along the first direction, so as to drive the second press belt block to contact with the first material strap a, and further compress the first material strap a in the first absorbing area 2211. Then, the second belt pressing driving member continues to drive the second moving seat to move close to the first absorbing area 2211 along the first direction, so as to compress the second elastic buffer member, and further drive the second cutting blade 27 to continue to move towards the first material belt a until the second cutting blade 27 cuts off the start end of the first material belt a. Alternatively, the second resilient buffer may be a spring. The second press belt block can be arranged on the second movable seat through the guide rod and the guide sleeve, so that the second press belt block can move along the first direction relative to the second movable seat under the guiding action of the guide rod and the guide sleeve.

It should be noted that, in other embodiments, the first cutting blade 26 may be provided with a driving mechanism to drive the first cutting blade 26 to move along the first direction, so as to cut the beginning end of the second material tape.

Of course, the second cutting blade 27 may also be provided with a driving mechanism to drive the second cutting blade 27 to move along the first direction, so as to cut the leading end of the first material strap a.

In a specific embodiment, the reel changer further comprises a connecting plate 30, and the connecting plate 30 is fixedly connected to the sliding base 222 to move synchronously with the sliding base 222 along the second direction. The first unwinding mechanism 11 and the second unwinding mechanism 12 are disposed on the connecting plate 30 along the second direction.

Further, the first adsorption mechanism 22 further includes a limit rod 227, and the fixing base 2261 is provided with a limit hole or a limit groove. The position-limiting rod 227 is slidably fitted in the position-limiting hole or the position-limiting groove, and one end of the position-limiting rod 227 is fixedly connected with the first adsorption seat 221. More specifically, one end of the limiting rod 227 departing from the first adsorption seat 221 has a limiting portion, and the limiting portion can abut against one side of the fixing seat 2261 departing from the first adsorption seat 221 in the process that the limiting rod 227 slides along the limiting hole or the limiting groove, so as to limit the moving range of the first adsorption seat 221 along the first direction.

In particular, in the embodiment, the unwinding assembly 10 further includes a first roller 14 and a second roller 15. The first roller 14 is rotatably connected to the connecting plate 30 around its axis and located between the first unwinding mechanism 11 and the reel changing assembly, so as to guide the first material tape a unwound and output by the first unwinding mechanism 11 to a position between the first suction seat 221 and the second suction seat 231. The second roller 15 is rotatably connected to the connecting plate 30 around its axis and located between the second unwinding mechanism 12 and the reel changing assembly, so as to guide the second material tape unwound and output by the second unwinding mechanism 12 to a position between the first suction seat 221 and the second suction seat 231.

It should be noted that the second driving member 226 is not necessary, that is, in another embodiment, please refer to fig. 6 and 7, the sliding seat 222 is only movable in the second direction by the first driving member 223, but not movable in the first direction, that is, the first suction seat 221 can only move with the sliding seat 222 in the second direction, but not movable in the first direction. At this time, the first material tape a or the second material tape is pressed only by the movement of the second suction seat 231 along the first direction. Therefore, the second driving member 226, the fixing seat 2261, the limiting rod 227 and other parts are omitted, the structure is simplified, and the equipment cost is reduced.

Referring to fig. 1, in the embodiment of the present invention, the second adsorption mechanism 23 further includes a lifting seat 232 and a third driving member 233. The lifting base 232 is movably connected to the mounting base 21 along a first direction, and the second suction base 231 is connected to the lifting base 232. The third driving member 233 is mounted on the mounting base 21 and is in transmission connection with the lifting base 232 to drive the lifting base 232 to move along the first direction, so as to drive the second adsorption base 231 to approach or leave the first adsorption base 221 along the first direction. Alternatively, the third driving member 233 may be a cylinder.

Referring to fig. 1 and 5, in some embodiments, the cutting mechanism 24 includes a guide base 241, a cutting blade 242 and a fourth driving member 245, wherein the cutting blade 242 is mounted on the guide base 241.

Thus, when the second suction seat 231 and the first suction seat 221 clamp the first material strip a or the second material strip during the roll changing process, the fourth driving member 245 drives the guide seat 241 to move along the first direction to drive the cutting knife 242 to move along the first direction, so that the cutting knife 242 cuts off the clamped first material strip a or the clamped second material strip during the movement of the cutting knife 242 along the first direction. Alternatively, the fourth driving member 245 may be a cylinder.

Further, the first adsorption seat 221 is provided with a cutter groove 2215 corresponding to the cutter 242, so that when the cutter 242 moves towards the first adsorption seat 221 along the first direction to cut the first material strap a or the second material strap, the cutter 242 cuts into the cutter groove 2215, thereby preventing the cutter 242 from being damaged due to contact with the first adsorption seat 221. Further, a cutter groove 2215 is formed between the first adsorption area 2211 and the third adsorption area 2213, and a cutter groove 2215 is also formed between the second adsorption area 2212 and the fourth adsorption area 2214.

That is, the cutter 242 is located between the pressing block 243 and the second suction seat 231. The elastic member 245 is disposed between the pressing block 243 and the guide seat 241 to provide a pre-load force that tends to make the pressing block 243 approach toward the first adsorption seat 221 in the first direction. Thus, after the lifting seat 232 drives the second adsorption seat 231 to approach the first adsorption seat 221 to clamp the first material strip a or the second material strip, the fourth driving member 245 drives the guide seat 241 to drive the cutter 242 and the pressing block 243 to approach the first adsorption seat 221, so that the pressing block 243 presses the first material strip a or the second material strip against the first adsorption seat 221 (at this time, the elastic member 245 is compressed), and then the cutter 242 cuts off the first material strip a or the second material strip. Alternatively, the elastic member 245 may be a spring.

It should be noted that, in the process that the guide seat 241 drives the cutter 242 and the pressing block 243 to approach the first adsorption seat 221, the guide seat 241 presses the first material tape a or the second material tape on the first adsorption seat 221, and then the cutter 242 contacts the first material tape a or the second material tape, so as to cut off the first material tape a or the second material tape.

Further, the cutting mechanism 24 further includes a guide rod 244, the guide rod 244 is slidably engaged with the guide seat 241, and the pressing block 243 is fixedly connected with one end of the guide rod 244 facing the first adsorption seat 221. More specifically, the guide holder 241 has a guide hole, and the guide rod 244 passes through the guide hole and is slidably engaged with the guide hole. One end of the guide rod 244, which is far away from the pressing block 243, is located on one side of the guide seat 241, which is far away from the pressing block 243, and is connected with a limit block 2411. During the sliding of the guide rod 244 relative to the guide seat 241 in the first direction, the limiting block may abut against a side of the guide seat 241 facing away from the pressing block 243 to limit a moving range of the guide rod 244 in the first direction. Alternatively, the guide bar 244 may include two or more.

Specifically, in an embodiment, the reel changer further includes a detector 40 disposed on the second adsorption mechanism 23, where the detector 40 is configured to detect an unwinding condition of the material roll on the first unwinding mechanism 11 when the first adsorption seat 221 is located at the first position, or detect an unwinding condition of the material roll on the second unwinding mechanism 12 when the first adsorption seat 221 is located at the second position, so that when the detector 40 detects that the unwinding of the material roll on the first unwinding mechanism 11 or the second unwinding mechanism 12 is completed, the first adsorption mechanism 22, the second adsorption mechanism 23, and the cutting mechanism 24 perform a reel changing operation. Alternatively, the detector 40 is mounted on the guide holder 241. The detector 40 may be a photosensor.

Referring to fig. 1 and fig. 2, the first adsorption seat 221 is located at a first position, a starting end of the second material tape unreeled and output by the second unreeling mechanism 12 is pressed against the second adsorption area 2212 by the first material pressing end 241 of the first belt pressing mechanism 24, the first material tape a unreeled and output by the first unreeling mechanism 11 passes through the first adsorption seat 221 and the second adsorption seat 231 and is conveyed downstream to an initial state, and a reel change process of the reel change device is described below:

when the roll unwinding of the roll in the first unwinding mechanism 11 is completed and a roll change is required, first, the first suction seat 221 and the second suction seat 231 are driven by the second driving element 226 and the third driving element 233 to approach each other (or, in an embodiment where the first suction seat 221 cannot move in the first direction, the second suction seat 231 is driven by the third driving element 233 to approach the first suction seat 221), so as to clamp the first tape a.

Then, the fourth driving member 245 drives the guide seat 241 to approach the first adsorption seat 221, so that the pressing block 243 presses the first material strip a, and the cutting blade 242 cuts the first material strip a as the guide seat 241 continues to approach the first adsorption seat 221. After the first tape a is cut, the fourth driving member 245 drives the guide holder 241 to return.

Then, at this time, the cut end of the first material tape a is adsorbed by the second adsorption seat 231, the end of the first material tape a connected to the material roll is adsorbed by the third adsorption area 2213, and the start end of the second material tape unreeled and output by the second unreeling mechanism 12 is adsorbed by the second adsorption area 2212. The second driving member 226 drives the first suction seat 221 to move away from the second suction seat 231 along the first direction (or, in an embodiment where the first suction seat 221 cannot move along the first direction, the second suction seat 231 is driven by the third driving member 233 to move away from the first suction seat 221), and then the first driving member 223 drives the first suction seat 221 to move along the second direction to the second position.

Then, the second driving element 226 drives the first suction seat 221 to approach the second suction seat 231 along the first direction (or, in an embodiment where the first suction seat 221 cannot move along the first direction, the second suction seat 231 approaches the first suction seat 221 under the driving of the third driving element 233), so that the cut end of the first material tape a sucked by the second suction seat 231 is adhered to the start end of the second material tape sucked by the second suction area 2212, thereby realizing the connection between the cut ends of the second material tape and the first material tape a.

Finally, the second suction holder 231 releases the suction of the cut end of the first tape a, and the second suction area 2212 of the first suction holder 221 releases the suction of the leading end of the second tape. And, the second driving unit 226 and the third driving unit 233 respectively drive the first suction seat 221 and the second suction seat 231 to move away from each other (or, in an embodiment where the first suction seat 221 cannot move in the first direction, the second suction seat 231 moves away from the first suction seat 221 under the driving of the third driving unit 233), so that the second material tape can be transported downstream through between the first suction seat 221 and the second suction seat 231.

The material roll on the first roll changing mechanism 11 is changed, and the starting end of the first material belt a unwound and output by the first roll changing mechanism 11 is pressed against the first adsorption area 2211 by the second pressing end 251 of the second belt pressing mechanism 25, so as to be ready for the next roll change.
