Referring to fig. 1 and 5, a roll changing apparatus according to an embodiment of the present invention includes an unwinding assembly, a roll changing assembly and a cutting assembly 40.
The unwinding assembly comprises a first unwinding mechanism 11 and a second unwinding mechanism 12, wherein the first unwinding mechanism 11 is used for unwinding and outputting a first material belt a, and the second unwinding mechanism 12 is used for unwinding and outputting a second material belt b. The reel changing assembly is arranged at the downstream of the unreeling assembly and comprises a first reel changing mechanism 21 and a second reel changing mechanism 22 which are oppositely arranged. A reel change passage c for the first material belt a and the second material belt b to pass through is formed between the first reel changing mechanism 21 and the second reel changing mechanism 22.
The first reel changer 21 is configured to be movable toward the second reel changer 22 to press the first and second tapes a, b against the second reel changer 22. The second reel changer 22 is configured to be movable towards the first reel changer 21 to press the first and second strips of material a, b against the first reel changer 21.
The cutting assembly 40 is used for cutting the first material belt a or the second material belt b pressed between the first reel changing mechanism 21 and the second reel changing mechanism 22.
The roll changing device is described by taking a first material belt a unreeled and output by the first unreeling mechanism 11 as a working material belt, and a second material belt b unreeled and output by the second unreeling mechanism 12 as a standby material belt. At this time, the first material tape a unwound and outputted by the first unwinding mechanism 11 passes through the reel change passage c between the first reel changer 21 and the second reel changer 22, and is outputted downstream. The second material belt b unwound and output by the second unwinding mechanism 12 passes through a reel changing passage c between the first reel changing mechanism 21 and the second reel changing mechanism 22 and is wound by the second reel changing mechanism 22.
When the material roll on the first unwinding mechanism 11 is used up and needs to be changed, the first reel changing mechanism 21 moves towards the second reel changing mechanism 22 until the first material strip a and the second material strip b in the reel changing channel c are pressed between the first reel changing mechanism 21 and the second reel changing mechanism 22, so that the first material strip a and the second material strip b are bonded. Then, the cutting assembly 40 cuts off an end of the first material tape a connected to the first unwinding mechanism 11, so as to connect the working material tape (the first material tape a) and the standby material tape (the second material tape b). Then, the first reel changing mechanism 21 moves away from the second reel changing mechanism 22 to reset, and the second material tape b unreeled and output by the second unreeling mechanism 12 passes through the reel changing channel c and is output downstream, that is, one-time reel changing is realized.
It should be noted that, a reel changing process in a case that the first material tape a unwound and outputted by the first unwinding mechanism 11 is a spare material tape, and the second material tape b unwound and outputted by the second unwinding mechanism 12 is a working material tape is similar to the above case, and therefore, details are not described herein.
Therefore, the utility model discloses a change the scroll device and can realize that the automatic switch-over of first material area a and second material area b is the work material area (automatic change of lap promptly), compares with the artifical change of lap mode that adopts among the prior art, has shortened greatly when shutting down, has improved production efficiency, and does not need personnel on duty, has reduced personnel's configuration to the cost of labor has been reduced.
It should be noted that the first material strip a and the second material strip b may be adhesive tapes, so that the first material strip a and the second material strip b pressed between the first reel changer 21 and the second reel changer 22 may be adhered to each other during the reel change. Of course, in other embodiments, the first and second tapes a, b may not be tapes. At this time, the first material belt a or the second material belt b on the material roll is pasted with double-sided adhesive tape, so that the first material belt a and the second material belt b are pasted in the process of changing the roll.
In the embodiment, the reel changing device further includes an installation plate 80, and the first unreeling mechanism 11, the second unreeling mechanism 12, the first reel changing mechanism 21, the second reel changing mechanism 22 and the cutting assembly 40 are all installed on the installation plate 80, so that the integration level of each mechanism of the reel changing device is improved, the size is reduced, and the space required to be occupied is saved.
Referring to fig. 1, fig. 2 and fig. 4, in an embodiment of the present invention, the first reel changing mechanism 21 includes a first fixing seat 212, a first driving member 213 and a first pushing block 214. The first fixing base 212 is fixedly connected to the mounting plate 80. The first driving member 213 is installed on the first fixing seat 212 and is in transmission connection with the first pushing block 214 to drive the first pushing block 214 to move toward the second reel changing mechanism 22, so as to press the first material tape a and the second material tape b penetrating through the reel changing channel c onto the second reel changing mechanism 22, and further to bond the first material tape a and the second material tape b. It should be noted that, when the first tape a is the spare tape, the first tape a passes through the reel changing channel c and then winds through the first pushing block 214. When the first material belt a is the working material belt, the first material belt a passes through the reel changing channel c and continues to be conveyed downstream. Alternatively, the first driver 213 may be a cylinder.
Further, a first slide rail may be disposed on the mounting plate 80, and a first slide block may be disposed on the first push block 214, and the first slide block is slidably engaged with the first slide rail, so as to guide the movement of the first push block 214 toward or away from the second reel changer 22. Of course, the first slide rail and the first slide block are not necessary, i.e. in some embodiments, the first slide rail and the first slide block may not be provided, and the first push block 214 may be directly installed at the driving end of the first driving member 213.
Referring to fig. 1, 2 and 4, in one embodiment of the present invention, the reel change assembly further includes a first pressing mechanism 211, the first pressing mechanism 211 includes a first pressing head 2114, and the first pressing head 2114 is configured to controllably press and fix the first material belt a to the first pushing block 214. Therefore, after the second material tape b is switched to the working material tape, a new material roll is replaced on the first unwinding mechanism 12, and the starting end of the first material tape a unwound from the first unwinding mechanism 12 (at this time, the first material tape a is a spare material tape) can pass through the unwinding passage c and bypass the first pushing block 214 by manual operation. The first ram 2114 then presses the first strip of material a against the first pusher 214 in preparation for the next reel change.
In some embodiments, first compression mechanism 211 further includes a first rotation shaft 2111, a first oscillation drive 2112, and a first pressure head seat 2113.
The first rotating shaft 2111 is rotatably disposed around its own axis, and is drivingly connected to a first swinging drive member 2112, and the first swinging drive member 2112 is used to drive the first rotating shaft 2111 to rotate around its own axis. One end of first pressure head holder 2113 is connected to first rotating shaft 2111, and the other end of first pressure head holder 2113 is mounted with first pressure head 2114.
In the process that the first rotating shaft 2111 drives the first pressing head seat 2113 to rotate, the first pressing head 2114 can press the first material strip a passing through the reel changing channel c against the first pushing block 214, so that the first material strip a is fixed relative to the first pushing block 214.
Specifically, in the embodiment, the first pressing mechanism 211 further includes a first cutter seat 2115, a first cutter 2116 and a first elastic member 2118. One end of the first cutter holder 2115 is connected to the first rotating shaft 2111, and the other end of the first cutter holder 2115 mounts the first cutter 2116 such that the first cutter 2116 can rotate with the first rotating shaft 2111. One end of the first pressure head seat 2113, which is away from the first pressure head 2114, is rotatably connected to the first rotating shaft 2111, and the first elastic element 2118 is connected to the first rotating shaft 2111 and the first pressure head seat 2113, where the first elastic element 2118 is used to provide a pre-tightening force that causes the first pressure head seat 2113 to have a tendency of driving the first pressure head 2114 to rotate toward the first pushing block 214, so that the first pressure head 2114 can drive the first pressure head seat 2113 to rotate relative to the first rotating shaft 2111 under the action of an external force, overcoming the pre-tightening force provided by the first elastic element 2118.
In the process that the first rotating shaft 2111 drives the first presser bit seat 2113 and the first cutter seat 2115 to rotate, the first presser bit 2114 can press the first material tape a (i.e., the spare material tape) passing through the reel changing channel c to the first push block 214 of the first reel changing mechanism 21, and the first cutter 2116 can cut off the first material tape a pressed to the first push block 214 of the first reel changing mechanism 21 by the first presser bit 2114, so that the length of the start end of the first material tape a is ensured to be consistent when the reel is changed every time, and the splicing effect is improved. Specifically, the first rotating shaft 2111 is rotatably mounted to the mounting plate 80 about its own axis.
Thus, after the first material strip a is pulled to pass through the reel changing channel c and pass through the first pushing block 214, the first swinging driving element 2112 drives the first rotating shaft 2111 to rotate, so as to drive the first pressing head 2114 to rotate to approach the first pushing block 214, so as to press the first material strip a passing through the first pushing block 214 against the first pushing block 214 of the first reel changing mechanism 21. Meanwhile, the first cutter 2116 rotates along with the first rotating shaft 2111 to be close to the first pushing block 214 of the first reel changing mechanism 21 until the first material tape a pressed on the first pushing block 214 by the first pressing head 2114 is cut off, so that the subsequent splicing of the first material tape a and the second material tape b is facilitated, and the splicing effect is improved.
When the first material tape a wound by the first pushing block 214 needs to be pressed and cut, first, the first swinging driving member 2112 drives the first rotating shaft 2111 to rotate, so that the first pressing head 2114 is driven by the first pressing head seat 2113 to rotate to be close to the first pushing block 214 of the first reel changing mechanism 21, and simultaneously the first cutting blade 2116 is driven by the first cutting blade seat 2115 to rotate to be close to the first pushing block 214 of the first reel changing mechanism 21. When the first pressing head 2114 rotates to contact with the first material strip a on the first pushing block 214 of the first reel changing mechanism 21 and press the first material strip a against the first pushing block 214 of the first reel changing mechanism 21, the first rotating shaft 2111 continues to rotate, so that the first cutting blade 2116 is driven to rotate by the first cutting blade holder 2115 to be close to the first pushing block 214 of the first reel changing mechanism 21 until the first cutting blade 2116 cuts off the first material strip a. That is to say, in the process that the first rotating shaft 2111 drives the first pressing head 2114 and the first cutting blade 2116 to rotate through the first pressing head seat 2113 and the first cutting blade seat 2115 respectively and approach the first pushing block 214 of the first reel changing mechanism 21, the first pressing head 2114 firstly presses the first material tape a on the first pushing block 214 of the first reel changing mechanism 21, and then the first cutting blade 2116 contacts with the first material tape a to cut off the first material tape a, which is beneficial to improving the quality of the section and improving the cutting effect.
It should be noted that, the first pressing head 2114 and the first cutting blade 2116 swing around the first rotating shaft 2111 by the rotation of the first rotating shaft 2111, so as to further achieve the pressing and cutting of the first material tape a, which is beneficial to reduce the space occupied by the first pressing mechanism 211 and improve the structural compactness of the reel changer compared with the mode of linear movement.
In an embodiment, the first pushing block 214 has a first cutting groove 2141 on a side facing the first cutting blade 2116, and the first cutting groove 2141 is disposed corresponding to the first cutting blade 2116. In this way, the first cutting blade 2116 rotates along with the first rotating shaft 2111 to approach the first pushing block 214 until cutting into the first cutting groove 2141, so as to cut the first material strap a pressed against the first pushing block 214 by the first pressing head 2114, thereby preventing the first cutting blade 2116 from contacting and damaging the first pushing block 214.
Alternatively, the first elastic member 2118 may be a torsion spring. The first elastic element 2118 is disposed around the first rotation shaft 2111, and a torsion arm of the first elastic element 2118 is connected to the first pressure head seat 2113, and another torsion arm of the first elastic element 2118 is fixed to the first rotation shaft 2111. Further, the first rotating shaft 2111 is fixedly fitted with a first fixing ring 2119 (see fig. 4), and a torsion arm of the first elastic member 2118 fixedly disposed with respect to the first rotating shaft 2111 is connected to the first fixing ring 2119. A first limiting plate is fixedly mounted on the first rotating shaft 2111, and the first pressure head seat 2113 abuts against the first limiting plate under the action of the first elastic element 2118, so that the first pressure head seat 2113 is limited.
Specifically, in one embodiment, the first swinging driving member 2112 includes a first driving body and a first telescopic end that is telescopic relative to the first driving body. The first drive body is hingedly connected to the mounting plate 80. The first pressing mechanism 211 further includes a first hinge 2117, one end of the first hinge 2117 is connected to the first rotating shaft 2111, and the other end of the first hinge 2117 is hinged to the first telescopic end. In this way, the first retractable end of the first swinging driving element 2112 can be retracted relative to the first driving body, so that the first rotating shaft 2111 is driven to rotate by the first hinge 2117, and the first pressing head 2114 and the first cutting blade 2116 swing around the first rotating shaft 2111, and the first material belt a is pressed and cut. Alternatively, first oscillating drive 2112 may be a pneumatic cylinder.
It should be noted that, by using the expansion of the first expansion end to realize the swing of the first pressure head 2114 and the first cutter 2116 around the first rotating shaft 2111, the distance between the first pressure head 2114 and the first cutter 2116 and the first rotating shaft 2111 and the distance between the first expansion end and the first rotating shaft 2111 can be designed, so that the first pressure head 2114 and the first cutter 2116 are driven to respectively compress and cut the first material strip a by using a smaller expansion stroke of the first expansion end, the space occupied by the first compressing mechanism 211 is further reduced, and the structural compactness of the reel changer is improved.
It should be noted that the first pressing mechanism 211 is not limited to the first pressing head and the first cutting knife swinging to press and cut the first material tape a. Referring to fig. 5 to 8, in other embodiments, the first pressing head 2114 and the first cutting blade 2116 of the first pressing mechanism 211 may also perform pressing and cutting of the first material strip a by linear movement. In this embodiment, the first pressing mechanism 211 further includes a first movable driving element 21121 and a first mounting seat 21122. The first pressing head 2114 is mounted on the first mounting seat 21122, and the first mounting seat 21122 is mounted at the driving end of the first movable driving member 21121 to be driven by the first movable driving member 21121 to move along the first direction, so as to drive the first pressing head 2114 to approach or separate from the first pushing block 214, and to press or release the first material belt a passing through the first pushing block 214.
In an embodiment, the first pressing mechanism 211 further includes a first cutting blade 2116 and a first elastic member 2118, and the first cutting blade 2116 is disposed on the first mounting seat 21122, so that the first cutting blade 2116 is close to or away from the first pushing block 214 along with the first mounting seat 21122 along the first direction. The first pressing head 2114 is movably connected to the first mounting seat 21122 along the first direction, and the first elastic member 2118 abuts against the first pressing head 2114 and the first mounting seat 21122 to provide a pre-tightening force that causes the first pressing head 2114 to have a tendency to move toward the first pushing block 214 along the first direction. Alternatively, the first movement drive 21121 may be a pneumatic cylinder. The first elastic member 2118 may be a spring.
Thus, after the first tape a is pulled to pass through the reel changing channel c and to wrap around the first pushing block 214 (at this time, the first tape a is a spare tape), the first moving driving element 21121 drives the first mounting seat 21122 to move toward the first pushing block 214 along the first direction, so as to drive the first pressing head 2114 to approach the first pushing block 214 along the first direction, so as to press the first tape a wrapped around the first pushing block 214 against the first pushing block 214. Meanwhile, the first cutting blade 2116 follows the first mounting seat 21122 to approach the first push block 214 along the first direction until the first material tape a pressed on the first push block 214 by the first pressing head 2114 is cut off, so as to facilitate the subsequent splicing of the first material tape a and the second material tape b.
It should be noted that, the first pressing head 2114 and the first cutting blade 2116 are driven by the first moving driving element 21121 to move along the first direction to press and cut the first material tape a, so that the structure of the first pressing mechanism 211 is simplified, and the pressing and cutting actions are more stable and reliable.
Further, the first pressing mechanism 211 further includes a first guide post 21123 and a first stopper 21124. The first mounting seat 21122 is provided with a first guide hole, and the first guide post 21123 is disposed through the first guide hole and is in sliding fit with the first guide hole. The first stopper 21124 is fixedly connected to an end of the first guide post 21123 for preventing the first guide post 21123 from disengaging from the first mounting seat 21122. The other end of the first guide post 21123 is fixedly connected to the first pressing head 2114, and the first elastic member 2118 abuts between the first mounting seat 21122 and the first pressing head 2114. In this way, the first guide post 21123 and the first guide hole are used to guide the movement of the first press head 2114, so that the action of the first press head 2114 to press or release the first material strap a is more stable and reliable. It should be noted that the first mounting seat 21122 may be provided with a plurality of mutually parallel first guide holes, each first guide hole is provided with a first guide post 21123 in a sliding fit manner, end portions of all the first guide posts 21123 located on the same side of the first mounting seat 21122 are fixedly connected to the first limiting block 21124, and end portions of all the first guide posts 21123 located on the other side of the first mounting seat 21122 are fixedly connected to the first pressing head 2114. In this way, the movement of the first presser 2114 is guided by the plurality of first guide posts 21123, and the stability and reliability of the operation of pressing or releasing the first tape a by the first presser 2114 are further improved.
Referring to fig. 2 and fig. 6, in an embodiment of the present invention, the first pushing block 214 has a first tape winding surface 2143 for the first material tape a passing through the reel changing channel c, and the first tape winding surface 2143 and the first pressing head 2114 are disposed correspondingly, so that the first pressing head 2114 can press the first material tape a against the first tape winding surface 2143. In this way, when the start end of the first material strap a needs to be pressed and cut, the first pressing head 2114 and the first cutting knife 2116 are driven by the first swinging driving element 2112 or the first moving driving element 21121 to swing or move toward the first tape winding surface 2143 of the first pushing block 214, first the first pressing head 2114 contacts the first material strap a and presses the first material strap a onto the first tape winding surface 2143, and then the first cutting knife 2116 contacts the first material strap a pressed onto the first tape winding surface 2143 to cut the first material strap a.
In an embodiment, the first pushing block 214 further has a first pressing surface 2142 as a side surface facing the second reel changing mechanism 22, and the first winding surface 2143 is engaged with an end of the first pressing surface 2142 at the output end of the reel changing channel c. Thus, when the first tape a is a spare tape, the first unwinding mechanism 11 unwinds and outputs the first tape a, and the first tape a passes through the input end of the reel changing channel c to the output end of the reel changing channel c along the first pressing surface 2142, and winds through the first push block 214 along the first tape winding surface 2143.
The first pressure surface 2142 is provided with a first guide roller 215 at an end thereof located at an input end of the winding path c, and/or the first pressure surface 2142 is provided with a second guide roller 216a at an end thereof located at an output end of the winding path c. In this way, the first material belt a is guided by the first guide roller 215 and/or the second guide roller 216a, so that the first material belt a is prevented from being scratched by the first push block 214 directly contacting the first material belt a. It is understood that the first guide roller 215 and the second guide roller 216a are both rotatable about their own axes with respect to the first push block 214.
Further, a third guide roller 217 is disposed at an end of the first strip winding surface 2143 away from the first pressing surface 2142, and the first strip a wound around the first strip winding surface 2143 is guided by the third guide roller 217, so that the first strip a is prevented from being scratched by the first pushing block 214.
It should be noted that the first pressing mechanism 211 is not necessary, and in other embodiments, the first material strap a may be fixed to the first pushing block 214 by vacuum suction. Specifically, the first pushing block 214 has a first tape winding surface 2143 for the first tape a passing through the reel changing passage c, and the first tape winding surface 2143 is configured to absorb the first tape a passing through.
Further, the first tape winding surface 2143 is provided with a plurality of suction holes connected to an external vacuum source, so that the first tape a wound through the suction holes is sucked. When the first material belt a needs to be loosened, the connection between each adsorption hole and an external vacuum source is cut off.
Of course, it can be understood that, in order to improve the splicing effect, a cutting mechanism may be provided to cut the leading end of the first material strip a that is adsorbed and fixed on the first tape winding surface 2143 of the first pushing block 214, so as to ensure good consistency of the length of the leading end of the first material strip a as the spare material strip during each roll change. It will be appreciated that the cutting mechanism is mounted to the mounting plate 80 and is positioned to correspond to the first strap winding surface 2143. As for the specific structure of the cutting mechanism, a structure that the air cylinder drives the cutter may be adopted, and other cutting structures in the prior art may also be adopted as long as the first material belt a can be cut, which is not limited herein.
Referring to fig. 1 and fig. 2, in an embodiment of the present invention, the first reel changing mechanism 21 further includes a first clamping mechanism 216, and the first clamping mechanism 216 includes a first clamping driving member 2161 and a first clamping block 2162 in transmission connection with the first clamping driving member 2161. The first clamping driving member 2161 is used for driving the first clamping block 2162 to clamp the first material belt a pressed between the first reel changing mechanism 21 and the second reel changing mechanism 22. The cutting assembly 40 is used for cutting off the first material tape a from a position between the input end of the reel changing passage c and the first clamping block 2162. Thus, the two sides of the position where the first material belt a is cut by the cutting assembly 40 are respectively clamped and fixed by the first clamping mechanism 216, the first reel changing mechanism 21 and the second reel changing mechanism 22, which is beneficial to improving the section quality and ensuring the cutting effect. Alternatively, the first clamp drive 2161 may be a clamp cylinder.
Specifically, in the embodiment, the first clamping driving member 2161 is installed on the first fixing seat 212 and is located on a side of the first pushing block 214 facing away from the first pressing head 2114. Therefore, during roll changing, the cutting assembly 40 can be cut off at a position between the portion of the first material strap a pressed by the first pushing block 214 on the second roll changing mechanism 22 and the portion clamped and fixed by the first clamping block 2162, so that the first material strap a is disconnected from the first unwinding mechanism 11 and is bonded with the second material strap b unwound by the second unwinding mechanism 12, and roll changing is realized.
The first clamping mechanism 216 is not essential, and the first clamping mechanism 216 may not be provided in a case where the cutting effect of the cutting unit 40 to cut the first tape a can be ensured.
It should be further noted that the input end of the reel changing channel c refers to an end into which the first material strip a and the second material strip b enter, and the output end of the reel changing channel c refers to an end out of which the first material strip a and the second material strip b exit. Specifically, in the embodiment shown in fig. 1, the lower end of the roll changing channel c is an input end, and the upper end of the roll changing channel c is an output end. Specifically, in the embodiment shown in fig. 5, the left end of the roll changing channel c is an input end, and the right end of the roll changing channel c is an output end.
Referring to fig. 1 and fig. 3, in an embodiment of the present invention, the second reel changing mechanism 22 includes a second fixing seat 222, a second driving member 223 and a second pushing block 224. The second fixing base 222 is fixedly connected to the mounting plate 80. The second driving member 223 is mounted on the second fixing seat 222 and is in transmission connection with the second pushing block 224 to drive the second pushing block 224 to move toward the first pushing block 214 of the first reel changing mechanism 21, so as to press the first material tape a and the second material tape b penetrating through the reel changing channel c against the first pushing block 214 of the first reel changing mechanism 21, and further bond the first material tape a and the second material tape b. It should be noted that, when the second material tape b is the spare material tape, the second material tape b passes through the second pushing block 224 after passing through the reel changing channel c. And when the second material belt b is a working material belt, the second material belt b passes through the reel changing channel c and is continuously conveyed to the downstream. Alternatively, the second driver 223 may be a cylinder.
Referring to fig. 5 and fig. 6, further, a second slide rail may be disposed on the mounting plate 80, and a second sliding block is disposed on the second pushing block 224, and the second sliding block is slidably engaged with the second slide rail, so as to guide the movement of the second pushing block 224 toward or away from the first reel changer 21. Alternatively, the first slide rail and the second slide rail may be the same slide rail, i.e. the first slide block and the second slide block share the same slide rail.
Of course, the second slide rail and the second slider are not necessary, and in some embodiments (such as the embodiment shown in fig. 1), the second slide rail and the second slider may not be provided, and the second push block 224 may be directly installed at the driving end of the second driving member 223.
With continued reference to fig. 1 and 3, in one embodiment of the present invention, the reel change assembly further comprises a second pressing mechanism 221, the second pressing mechanism 221 comprises a second pressing head 2214, and the second pressing head 2214 is configured to controllably press and fix the second material strap b to the second pushing block 224. Therefore, after the first material tape a is switched to the working material tape, a new material roll is replaced on the second unwinding mechanism 22, and the beginning end of the second material tape b unwound from the second unwinding mechanism 22 (at this time, the second material tape b is the standby material tape) can pass through the unwinding passage c and bypass the second push block 224 manually. The second ram 2214 then presses and fixes the second strip b to the second pusher 224 in preparation for the next reel change.
In some embodiments, the second pressing mechanism 221 further comprises a second rotating shaft 2211, a second swinging driver 2212 and a second pressing head seat.
The second rotating shaft 2211 is rotatably disposed around its axis and is in transmission connection with a second swinging driving member 2212, and the second swinging driving member 2212 is used for driving the second rotating shaft 2211 to rotate around its axis. One end of the second pressure head base is connected to the second rotating shaft 2211, and the other end of the second pressure head base is provided with the second pressure head 2214.
In the process that the second rotating shaft 2211 drives the second pressing head seat to rotate, the second pressing head 2214 can press the second material strip b penetrating through the reel changing channel c onto the second pushing block 224, so that the second material strip b is fixed relative to the second pushing block 224.
In one embodiment, the second pressing mechanism 221 further includes a second cutter holder 2215, a second cutter 2216 and a second elastic member 2218. One end of the second cutter holder 2215 is connected to the second rotating shaft 2211, and the other end of the second cutter holder 2215 is provided with the second cutter 2216, so that the second cutter 2216 can rotate along with the second rotating shaft 2211. One end of the second pressing head seat departing from the second pressing head 2214 is rotatably connected to the second rotating shaft 2211, the second elastic element 2218 is connected to the second rotating shaft 2211 and the second pressing head seat, the second elastic element 2218 is used for providing a pre-tightening force that enables the second pressing head seat to have a trend of driving the second pressing head 2214 to rotate towards the second pushing block 224, so that the second pressing head 2214 can drive the second pressing head seat to overcome the pre-tightening force provided by the second elastic element 2218 under the action of an external force and rotate relative to the second rotating shaft 2211.
Wherein, second pivot 2211 drives second pressure head seat and second cutter holder 2215 pivoted in-process, second pressure head 2214 can compress tightly in the second pusher 224 of second change of lap mechanism 22 with wearing out the second material area b (being reserve material area) of changing a roll passageway c, second cutter 2216 can cut off and be compressed tightly the second material area b on the second pusher 224 of second change of lap mechanism 22 by second pressure head 2214 to ensure that the length of the start end of second material area b is unanimous when changing a lap at every turn, be favorable to improving the area effect of connecing. Specifically, the second rotating shaft 2211 is rotatably mounted to the mounting plate 80 about its axis.
Thus, after the second material strip b is pulled to pass through the reel changing channel c and wind around the second pushing block 224, the second swinging driving member 2212 drives the second rotating shaft 2211 to rotate, so as to drive the second pressing head 2214 to rotate and approach the second pushing block 224 of the second reel changing mechanism 22, so as to press the second material strip b wound around the second pushing block 224 of the second reel changing mechanism 22 to the second pushing block 224. Meanwhile, the second cutter 2216 rotates along with the second rotating shaft 2211 to be close to the second push block 224 of the second reel changing mechanism 22 until the second material belt b pressed by the second pressing head 2214 on the second push block 224 is cut off, so that the subsequent splicing of the first material belt a and the second material belt b is facilitated, and the splicing effect is improved.
When the second material tape b wound by the second pushing block 224 of the second reel changing mechanism 22 needs to be compressed and cut, first, the second swinging driving member 2212 drives the second rotating shaft 2211 to rotate, so that the second pressing head 2214 is driven to rotate by the second pressing head seat to be close to the second pushing block 224 of the second reel changing mechanism 22, and the second cutting knife 2216 is driven to rotate by the second cutting knife seat 2215 to be close to the second pushing block 224 of the second reel changing mechanism 22. When the second pressing head 2214 rotates to contact with the second material strip b on the second pushing block 224 of the second reel changing mechanism 22 and press the second material strip b against the second pushing block 224 of the second reel changing mechanism 22, the second rotating shaft 2211 continues to rotate, so that the second cutting knife 2216 is driven to rotate by the second cutting knife holder 2215 to be close to the second pushing block 224 of the second reel changing mechanism 22, until the second cutting knife 2216 cuts off the second material strip b. That is to say, in the process that the second rotating shaft 2211 drives the second pressing head 2214 and the second cutter 2216 to rotate through the second pressing head seat and the second cutter seat 2215 respectively and to approach the second push block 224 of the second reel changing mechanism 22, the second pressing head 2214 firstly presses the second material strip b to the second push block 224 of the second reel changing mechanism 22, and then the second cutter 2216 contacts with the second material strip b to cut off the second material strip b, which is beneficial to improving the quality of the section and improving the cutting effect.
It should be noted that, the second rotating shaft 2211 rotates to swing the second pressing head 2214 and the second cutting knife 2216 around the second rotating shaft 2211, so as to compress and cut the second material strap b.
In an embodiment, a side of the second pushing block 224 facing the second cutting knife 2216 is provided with a second cutting groove 2241, and the second cutting groove 2241 is arranged corresponding to the second cutting knife 2216. Therefore, the second cutter 2216 rotates along with the second rotating shaft 2211 to be close to the second push block 224 until being cut into the second cutting groove 2241, so that the second material belt b pressed on the second push block 224 by the second pressing head 2214 is cut off, and the second cutter 2216 is prevented from being damaged due to contact with the second push block 224.
Alternatively, the second elastic member may be a torsion spring. The second elastic member is sleeved on the second rotating shaft 2211, and one torsion arm of the second elastic member is connected to the second head base, and the other torsion arm of the second elastic member is fixedly disposed relative to the second rotating shaft 2211. Further, a second fixing ring is fixedly secured to the second rotating shaft 2211, and a torsion arm of the second elastic member fixedly disposed relative to the second rotating shaft 2211 is connected to the second fixing ring. A second limiting plate is fixedly mounted on the second rotating shaft 2211, and the second press head seat abuts against the second limiting plate under the action of the second elastic piece, so that the second press head seat is limited.
In one embodiment, the second swing driving element 2212 includes a second driving body and a second telescopic end that is telescopic relative to the second driving body. The second drive body is hingedly connected to the mounting plate 80. The second pressing mechanism 221 further includes a second hinge 2217, one end of the second hinge 2217 is fixedly connected to the second rotating shaft 2211, and the other end of the second hinge 2217 is hinged to the second telescopic end. So, the flexible end of second of accessible second swing driving piece 2212 is flexible relative to the second drive body to drive second pivot 2211 through second articulated elements 2217 and rotate, and then realize that second pressure head 2214 and second cutter 2216 swing around second pivot 2211, and realize compressing tightly and cut off second material area b. Alternatively, the second swing drive 2212 may be a pneumatic cylinder.
It should be noted that, the second pressing head 2214 and the second cutter 2216 swing around the second rotating shaft 2211 by using the extension and contraction of the second telescopic end, the distance between the second pressing head 2214 and the second cutter 2216 and the second rotating shaft 2211 and the distance between the second telescopic end and the second rotating shaft 2211 can be designed, the second pressing head 2214 and the second cutter 2216 can be driven to respectively press and cut the second material strip b by using the smaller extension and contraction stroke of the second telescopic end, the space occupied by the second pressing mechanism 221 is further reduced, and the structural compactness of the coil changing device is improved.
It should be noted that the second pressing mechanism is not limited to the second pressing head and the second cutting knife swinging to press and cut the second material tape b. Referring to fig. 5, 9 and 10, in other embodiments, the second pressing head 2214 and the second cutting knife 2216 of the second pressing mechanism 221 may also perform pressing and cutting on the second material strip b by linear movement. In this embodiment, the second pressing mechanism 221 further includes a second movable driving member 22121 and a second mounting seat 22122. The second pressing head 2214 is mounted on the second mounting seat 22122, and the second mounting seat 22122 is mounted on the driving end of the second movable driving member 22121 to be driven by the second movable driving member 22121 to move in the first direction, so as to drive the second pressing head 2214 to approach or move away from the second pushing block 224, so as to press or release the second material strip b passing through the second pushing block 224.

The second pressing head 2214 is movably connected to the second mounting seat 22122 along the first direction, and the second elastic member 2218 abuts against the second pressing head 2214 and the second mounting seat 22122 to provide a pre-tightening force that makes the second pressing head 2214 have a tendency to move towards the second pushing block 224 along the first direction. Alternatively, the second movement drive 22121 may be a pneumatic cylinder. The second elastic member 2218 may be a spring.
Thus, after the second material strip b is pulled to pass through the reel changing channel c and to wind around the second pushing block 224 (at this time, the second material strip b is a spare material strip), the second moving driving member 22121 drives the second mounting seat 22122 to move towards the second pushing block 224 along the first direction, so as to drive the second pressing head 2214 to approach the second pushing block 224 along the first direction, so as to press the second material strip b wound around the second pushing block 224 onto the second pushing block 224. Meanwhile, the second cutter 2216 follows the second mounting seat 22122 to approach the second push block 224 along the first direction until the second material strip b pressed against the second push block 224 by the second press head 2214 is cut off, so as to facilitate the subsequent splicing of the first material strip a and the second material strip b.
It should be noted that, the second pressing head 2214 and the second cutting knife 2216 are driven by the second moving driving element 22121 to move along the first direction to press and cut the second material strap b, so that the structure of the second pressing mechanism 22 is simplified, and the pressing and cutting actions are more stable and reliable.

The other end of the second guide post 22123 is fixedly connected to the second pressing head 2214, and the second elastic member 2218 abuts between the second mounting seat 22122 and the second pressing head 2214. In this way, the second guide post 22123 is used to guide the movement of the second pressing head 2214, so that the pressing or releasing action of the second pressing head 2214 on the second material strip b is more stable and reliable. It should be noted that the second mounting seat 22122 may be provided with a plurality of second guide holes parallel to each other, each second guide hole is slidably fitted with a second guide post 22123, the end portions of all the second guide posts 22123 located on the same side of the second mounting seat 22122 are fixedly connected to the second stop block 22124, and the end portions of all the second guide posts 22123 located on the other side of the second mounting seat 22122 are fixedly connected to the second press head 2214. In this way, the movement of the second ram 2214 is guided by the plurality of second guide posts 22123, and the stability and reliability of the operation of pressing or releasing the second material strip b by the second ram 2214 are further improved.

In this way, when the start end of the second material strip b needs to be pressed and cut, the second pressing head 2214 and the second cutting knife 2216 are driven by the second swing driving element 2212 or the second moving driving element 22121 to swing or move towards the second strip winding surface 2243 of the second pushing block 224, so that the second pressing head 2214 first contacts the second material strip b and presses the second material strip b onto the second strip winding surface 2243, and then the second cutting knife 2216 contacts the second material strip b pressed onto the second strip winding surface 2243 to cut the second material strip b.
In a specific embodiment, the second pushing block 224 further has a second pressing surface 2242 as a side surface facing the first reel changing mechanism 21, and the second tape winding surface 2243 is engaged with an end of the second pressing surface 2242 at the output end of the reel changing passage c. Therefore, when the second material strip b is a spare material strip, the second unwinding mechanism 12 unwinds and outputs the second material strip b, and the second material strip b passes through the output end of the reel changing passage c from the input end of the reel changing passage c along the second pressing surface 2242, and winds through the second push block 224 along the second strip winding surface 2243.

In this embodiment, since the first correcting roller 31 can fix the first tape a when the first tape a is the spare tape, the first pressing head 2114 is not required to be used for pressing and fixing. Since the second correcting roller 32 can fix the second material strip b when the second material strip b is a spare material strip, the second pressing head 2214 is not required to be used for pressing and fixing. Specifically, both the first correcting roller 31 and the second correcting roller 32 may be mounted to the mounting plate 80.
