With continued reference to fig. 3, in an embodiment of the present application, the rubberizing mechanism includes a drive assembly 10 and a rubberizing assembly 20. The rubberizing assembly 20 comprises a swinging seat 21, a glue supply unit 23 and a press roller 22 both arranged on the swinging seat 21. The adhesive supply unit 23 is for supplying the double-sided adhesive tape C to the pressing roller 22. The driving assembly 10 is used for driving the swinging seat 21 to rotate so as to drive the press roller 22 to swing between the first unreeling station a1 and the second unreeling station a 2. The press roller 22 can be abutted against the material roll a on the first unreeling mechanism 101 when reaching the first unreeling station a1, and can be abutted against the material roll a on the second unreeling mechanism 102 when reaching the second unreeling station a 2. The driving assembly 10 is further used for driving the pressing roller 22 to roll along the surface of the material roll a through the swinging seat 21 so as to roll and adhere the double faced adhesive tape C provided by the adhesive supplying unit 23 to the material roll a.

In the above-mentioned rubberizing mechanism, when the material roll a located at the first unreeling station a1 needs to paste the double faced adhesive tape C, first, the driving assembly 10 drives the swinging seat 21 to rotate until the swinging seat 21 drives the press roller 22 to swing to the first unreeling station a1. At this time, the pressing roller 22 abuts against the roll a at the first unreeling station a1. Then, the adhesive supply unit 23 supplies the double-sided adhesive C to the pressing roller 22, and the driving assembly 10 drives the pressing roller 22 to roll along the surface of the roll a through the swinging seat 21 until the double-sided adhesive C supplied by the adhesive supply unit 23 is rolled and adhered to the roll a. At this time, the rubberizing of the roll a located at the first unreeling station a1 is completed.

When the double faced adhesive tape C is required to be adhered to the roll a located at the second unreeling station a2, first, the driving assembly 10 drives the swinging seat 21 to rotate until the swinging seat 21 drives the press roller 22 to swing to the second unreeling station a2. At this time, the pressing roller 22 abuts against the roll a at the second unreeling station a2. Then, the adhesive supply unit 23 supplies the double-sided adhesive C to the pressing roller 22, and the driving assembly 10 drives the pressing roller 22 to roll along the surface of the roll a through the swinging seat 21 until the double-sided adhesive C supplied by the adhesive supply unit 23 is rolled and adhered to the roll a. At this time, the rubberizing of the roll a located at the second unreeling station a2 is completed.

Therefore, the swinging seat 21 is utilized to drive the press roller 22 to swing between the first unreeling station a1 and the second unreeling station a2, and the swinging seat 21 is utilized to drive the press roller 22 to roll along the surface of the material roll A abutted against the press roller 22, so that the double faced adhesive tape C is rolled and adhered to the material roll A positioned at the first unreeling station a1 or the second unreeling station a2, the degree of automation is high, the operator is not required to watch, and the labor cost is reduced.

The press roller 22 is switched between the first unreeling station a1 and the second unreeling station a2 by using the swinging mode of the swinging seat 21, so that the switching is rapid and accurate, and the structure is simple. The double faced adhesive tape C is stuck to the surface of the material roll A by using the pressing roller 22 for rolling, so that the double faced adhesive tape C is stuck more flatly and firmly.

In particular, in the embodiment, the driving assembly 10 includes a supporting base 11, a first driving unit 12, a moving base 13, and a second driving unit 14. The motion seat 13 is movably connected to the support seat 11. The first driving unit 12 is mounted on the support base 11 and connected to the moving base 13, so that the first driving unit 12 can drive the moving base 13 to move relative to the support base 11. The oscillating seat 21 is rotatably connected to the moving seat 13, i.e. the oscillating seat 21 can rotate relative to the moving seat 13 and can also move along with the moving seat 13 relative to the supporting seat 11. The second driving unit 14 is mounted on the moving seat 13 and connected to the swing seat 21, so that the second driving unit 14 can drive the swing seat 21 to rotate relative to the moving seat 13. In this way, the second driving unit 14 can drive the swinging seat 21 to rotate relative to the moving seat 13, so that the swinging seat 21 drives the pressing roller 22 to swing between the first unreeling station a1 and the second unreeling station a 2. The first driving unit 12 can drive the moving seat 13 to move relative to the supporting seat 11, so that the moving seat 13 drives the swinging seat 21 and the pressing roller 22 on the swinging seat 21 to move together, and the pressing roller 22 rolls along the surface of the material roll A abutted with the pressing roller 22 so as to roll and adhere the double faced adhesive tape C to the material roll A.

Alternatively, the motion base 13 is moved in the first preset direction X1 by the driving of the first driving unit 12. The rotation axis of the swing seat 21 when rotated by the driving of the second driving unit 14 is parallel to the first preset direction X1 and perpendicular to the rotation axis of the pressing roller 22. In this way, under the driving action of the second driving unit 14, the swinging seat 21 drives the pressing roller 22 to abut against the material roll a located at the first unreeling station a1 or the second unreeling station a2, and the rotation axis of the pressing roller 22 is perpendicular to the axial direction of the material roll a. Under the driving action of the first driving unit 12, the motion seat 13 drives the swing seat 21 and the press roller 22 to move along the first preset direction X1, so that the press roller 22 rolls along the axial direction of the roll a on the surface of the roll a abutted against the press roller.

In particular, in the embodiment, one end of the swinging seat 21 is fixedly connected with a rotating shaft 211, and the rotating shaft 211 is assembled to the moving seat 13 through a bearing, so that the swinging seat 21 can rotate relative to the moving seat 13 along with the rotating shaft 211. The second driving unit 14 is connected to the rotating shaft 211 to drive the rotating shaft 211 to rotate around its own axis, so as to drive the swinging seat 21 to rotate together.

Optionally, the second driving unit 14 includes a motor and a timing belt. The motor is installed on the motion seat 13, and the output shaft of motor passes through the hold-in range and is connected with pivot 211 for can drive the pivot 211 through the hold-in range when the output shaft of motor rotates and rotate, pivot 211 drives the rotation of swing seat 21 again, and swing seat 21 drives compression roller 22 and unreels between station a1 and the second and unreels station a 2. The second driving unit 14 is not limited to a structure using a motor and a timing belt. In other embodiments, the second driving unit 14 may also adopt a structure such as a motor and a gear, which is not limited herein.

In the embodiment, the rubberizing assembly 20 includes a transfer base 25 and a third driving unit 24. The transfer base 25 is movably connected to the swing base 21, and the third driving unit 24 is mounted on the swing base 21 and connected to the transfer base 25. The pressing roller 22 is rotatably connected to the transfer base 25. The third driving unit 24 is used for driving the transferring base 25 to move along the second preset direction X2 relative to the swinging base 21 so as to drive the pressing roller 22 to approach or separate from the roll a. Thus, when the press roller 22 swings to the first unreeling station a1 or the second unreeling station a2 along with the swinging seat 21, the third driving unit 24 drives the transferring seat 25 to move relative to the swinging seat 21, so as to drive the press roller 22 to gradually approach the material roll a until the press roller 22 and the material roll a are abutted against each other. After the pressing roller 22 rolls along the surface of the roll a to roll the double faced adhesive tape C onto the roll a, the third driving unit 24 drives the transfer seat 25 to move relative to the swing seat 21, so as to drive the pressing roller 22 to gradually separate from the roll a, so that the pressing roller 22 is separated from the roll a.

Alternatively, the third driving unit 24 may employ a cylinder. Of course, in other embodiments, the third driving unit 24 may also employ a linear driving module, such as a motor and a screw, which is not limited herein.

Referring to fig. 4 and 5, in the embodiment of the application, the glue supply unit 23 includes an unreeling member 231, a stripping plate 232 and a reeling member 233, which are all disposed on the transfer base 25. The unreeling piece 231 is used for unreeling an output tape B (see fig. 2) downstream, the tape B comprising a release paper D and a plurality of the double-sided tape C described above attached to the same side of the release paper D. A peeling plate 232 is disposed downstream of the unreeling piece 231 for the tape B to wind around. The stripper plate 232 serves to separate the double-sided adhesive C from the separator D on the routed tape B and into between the press roll 22 and the roll a. A winding member 233 is disposed downstream of the peeling plate 232 for winding the separator paper D after passing through the peeling plate 232. Thus, when the pressing roller 22 abuts against the roll a, the tape B delivered downstream from the unreeling member 231 passes through the peeling plate 232 and is reeled by the reeling member 233, and the double-sided adhesive C on the tape B passing through the peeling plate 232 is separated from the release paper D under the action of the peeling plate 232 and enters between the pressing roller 22 and the roll a. At the same time, the pressing roller 22 rolls along the surface of the roll a (rolls upward as shown in fig. 5) under the driving action of the first driving unit 12 until the double-sided tape C that has entered between the pressing roller 22 and the roll a is rolled and stuck onto the roll a.

Further, the stripper plate 232 has a stripper end 2321 disposed opposite the press roll 22. The tape B is wound around the peeling end 2321 at an acute angle, that is, the tape B is wound around the peeling end 2321 from one side of the peeling plate 232 to the other side of the peeling plate 232, and the angle between the release paper D located on one side of the peeling plate 232 and the release paper D located on the other side of the peeling plate 232 is an acute angle. In this way, the adhesive tape B is greatly deformed when passing through the peeling end 2321, so that the double-sided adhesive C adhered to the side of the release paper D away from the peeling end 2321 receives the peeling force separated from the release paper D, and the double-sided adhesive C separated from the release paper D enters between the pressing roller 22 and the material roll a.

In particular embodiments, the rubberizing assembly 20 further includes a fixed mount 26, a floating mount 27, and an elastic member 28. The fixed support 26 is mounted on the transfer support 25, and the floating support 27 is movably connected to the fixed support 26 such that the floating support 27 can move relative to the fixed support 26. The pressure roller 22 is rotatably connected to the floating support 27 such that the pressure roller 22 can move with the floating support 27 relative to the fixed support 26. The elastic member 28 abuts between the fixed mount 26 and the floating mount 27 for providing a pretension force that causes the floating mount 27 to have a movement tendency to move away from the fixed mount 26. The side of the press roller 22 facing away from the fixed support 26 is adapted to abut against the roll a, so that the floating support 27 and the fixed support 26 are able to further compress the elastic member 28 under the pressing action of the roll a when the press roller 22 abuts against the roll a.

In this way, under the driving action of the third driving unit 24, the transfer seat 25 drives the pressing roller 22 to press against the material roll a. The pressing force of the material roll A applied to the pressing roller 22 is transferred to the floating support 27, and the floating support 27 moves towards the fixed support 26 under the action of the pressing force, so that the elastic piece 28 is further compressed, on one hand, the elastic piece 28 plays a role in buffering, and hard impact of the pressing roller 22 on the material roll A is avoided; on the other hand, under the action of the pre-tightening force provided by the elastic element 28, the compression roller 22 is ensured to be always kept in abutting contact with the material roll A during the process of rolling along the surface of the material roll A. Alternatively, the elastic member 28 may employ a spring.

Optionally, the fixed support 26 has a guide hole. The rubberizing assembly 20 further comprises a guide rod 29, wherein the guide rod 29 penetrates through the guide hole and can move along the axial direction of the guide hole. One end of the guide rod 29 is screwed with the floating mount 27. The elastic member 28 is sleeved on the guide rod 29, and two ends of the elastic member 28 are respectively abutted with the floating support 27 and the fixed support 26. In this way, the movement of the floating mount 27 relative to the fixed mount 26 is guided by the movement of the guide bar 29 along the guide hole.

Further, the rubberizing assembly 20 further comprises a sensing block 271 and a detecting member 261. The sensing block 271 is mounted on the floating mount 27 and the sensing piece 261 is mounted on the fixed mount 26. When the press roller 22 abuts against the roll a, the floating support 27 drives the sensing block 271 to move towards the fixed support 26 to the detecting member 261, so that the sensing block 271 is detected by the detecting member 261. Thus, when the detecting member 261 detects the sensing block 271, it indicates that the pressing roller 22 has been abutted against the roll a at this time, and therefore it can be determined whether the pressing roller 22 has been abutted against the roll a or not by the detection result of the detecting member 261. Alternatively, the detecting member 261 may employ a photoelectric sensor.

It should be noted that the release sheet 232 is not necessary, that is, the release sheet 232 is not limited to the use of the release sheet 232 to separate the double-sided tape C from the release paper D on the adhesive tape B. In other embodiments, referring to fig. 6, the glue supply unit 23 includes an unreeling member 231 and a reeling member 233, which are both disposed on the transfer base 25. The unreeling piece 231 is used for unreeling and delivering an adhesive tape B downstream, wherein the adhesive tape B comprises a release paper D and a plurality of double-sided tapes C stuck on the same side of the release paper D. The pressing roller 22 is disposed downstream of the unreeling piece 231 for pressing the double-sided tape C on the tape B passing by to the roll a so that the double-sided tape C on the tape B passing by the pressing roller 22 is stuck to the roll a and separated from the release paper D during the rolling of the pressing roller 22 along the surface of the roll a. The winding member 233 is used to wind the separator D passing through the pressing roller 22.

Thus, when the pressing roller 22 abuts against the roll a, the adhesive tape B output downstream from the unreeling member 231 is wound around the pressing roller 22 and then wound by the reeling member 233, the pressing roller 22 abuts against the roll a, and the side of the adhesive tape B to which the double-sided adhesive tape C is attached faces the roll a. While the separator D is wound up by the winding member 233, the pressing roller 22 is rolled along the surface of the roll a (rolled down as shown in fig. 6) by the driving of the first driving unit 12 until the double-sided tape C on the adhesive tape B wound around the pressing roller 22 is pressed against the roll a and separated from the separator D.
