The embodiment provides an automatic tape splicing device 10, and the automatic tape splicing device 10 can effectively splice new and old material rolls, solves the problem that the head and tail bonding positions of the new and old material rolls are folded in the prior art, and improves the splicing quality of diaphragms.

Referring to fig. 1, fig. 2 and fig. 3, fig. 1 shows a specific structure of an automatic tape splicing apparatus 10 provided in the present embodiment in a first viewing angle, fig. 2 shows a specific structure of the automatic tape splicing apparatus 10 provided in the present embodiment in a second viewing angle, and fig. 3 shows a specific structure of the automatic tape splicing apparatus 10 provided in the present embodiment in a third viewing angle.

The automatic belt splicing device 10 comprises a base body 11, a first belt splicing mechanism 12, a second belt splicing mechanism 13 and a discharging roller 14. The first tape splicing mechanism 12 and the second tape splicing mechanism 13 are mounted on the base body 11 and are oppositely arranged in the left-right direction, and each tape splicing mechanism (the first tape splicing mechanism 12 and the second tape splicing mechanism 13) can move left and right relative to the base body 11. The discharge roller 14 is mounted on the base 11 and located downstream of the first belt joining mechanism 12 and the second belt joining mechanism 13, and the discharge roller 14 is movable left and right relative to the base 11.

The first splicing mechanism 12 and the second splicing mechanism 13 are respectively used for unreeling an old material roll or a new material roll, and the new material roll is spliced between the first splicing mechanism 12 and the second splicing mechanism 13.

The web of separator material is fed through the outfeed roller 14, i.e. the old web is fed out by the outfeed roller 14 before the new web is joined, and the joined web of separator material is also fed out by the outfeed roller 14.

The inventor finds that the existing splicing device has the problem that the new and old material rolls are folded when being spliced, and the reason is that the new and old material rolls are not in the correct posture when being spliced, for example, the new and old material rolls have large inclination angles or large inclination angles, so that the new and old material rolls are overlapped when being spliced, and the folding problem is caused.

For this reason, in order to join the new and old material rolls in the correct posture, the first joining mechanism 12 and the second joining mechanism 13 provided in the present embodiment are moved relative to the base body 11 so as to be able to approach or separate from each other, and the discharging roller 14 is also able to move relative to the base body 11.

Taking the first splicing mechanism 12 for unreeling the old material roll and the second splicing mechanism 13 for unreeling the new material roll as an example, when splicing is performed, the old material roll can be debugged through the movement of the first splicing mechanism 12 and the discharging roller 14 (or the second splicing mechanism 13 and the discharging roller 14 (in this case, the first splicing mechanism 12 unreels the new material roll and the second splicing mechanism 13 unreels the old material roll)), so that the part of the old material roll which is to be spliced with the new material roll can approach the new material roll in a correct posture, the new material roll is spliced in the correct posture, the new material roll is prevented from being overlapped at the splicing position, the folding problem is avoided, and the splicing quality is improved.

Alternatively, in a possible implementation, the first splicing mechanism 12 includes a first mounting plate 120, and a first passing roller 121 and a first applying mechanism 122 disposed on the first mounting plate 120, the first mounting plate 120 is slidably connected to the base 11, and the first passing roller 121 is used for the material roll to pass through.

The second tape splicing mechanism 13 comprises a second mounting plate 130, a second roller 131 and a second rubberizing mechanism 132, wherein the second roller 131 and the second rubberizing mechanism 132 are arranged on the second mounting plate 130, the second mounting plate 130 is connected to the base body 11 in a sliding mode, and the second roller 131 is used for allowing a material supply roll to pass through.

The first glue applying mechanism 122 is used for driving the new roll with the gummed paper to move so as to apply the new roll to the old roll on the second tape splicing mechanism 13 between the second roller 131 and the discharging roller 14.

The second glue applying mechanism 132 is used for driving the new roll with the gummed paper to move so as to apply the new roll to the old roll on the first tape splicing mechanism 12 between the first roller 121 and the discharging roller 14.

When the first splicing mechanism 12 unwinds the old material roll and the second splicing mechanism 13 unwinds the new material roll, the second gluing mechanism 132 moves the new material roll to enable the new material roll to be glued to the old material roll on the first splicing mechanism 12 between the first passing roller 121 and the discharging passing roller 14.

In contrast, when the first splicing mechanism 12 unwinds the new roll and the second splicing mechanism 13 unwinds the old roll, the first gluing mechanism 122 moves the new roll to enable the new roll to be glued to the old roll on the second splicing mechanism 13 between the second passing roller 131 and the discharging passing roller 14.

Optionally, in a possible implementation, the automatic belt splicing device 10 further comprises a third mounting plate 140, the discharging roller 14 is arranged on the third mounting plate 140, and the third mounting plate 140 is slidably connected to the base body 11.

Referring to fig. 2, in the embodiment, the base 11 includes three sliding assemblies 11a, and the first mounting plate 120, the second mounting plate 130 and the third mounting plate 140 are slidably disposed on one sliding assembly 11a, respectively, so that the first mounting plate 120, the second mounting plate 130 and the third mounting plate 140 slide relative to the respective sliding assemblies 11 a.

Alternatively, in a possible implementation manner, the first mounting plate 120 is provided with a first pushing block 123, and during the process of moving the first splicing mechanism 12 toward the second splicing mechanism 13, when the first pushing block 123 contacts the third mounting plate 140, the first pushing block 123 pushes the third mounting plate 140 to move synchronously.

The second mounting plate 130 is provided with a second pushing block 133, and when the second pushing block 133 contacts the third mounting plate 140 in the process that the second tape splicing mechanism 13 moves towards the first tape splicing mechanism 12, the second pushing block 133 pushes the third mounting plate 140 to move synchronously.

The technical scheme provided by the invention can enable the automatic splicing device 10 to easily complete the position adjustment of the new and old material rolls at the splicing position, reduce the operation procedures and reduce the probability of misoperation, and takes the first splicing mechanism 12 to unreel the old material roll and the second splicing mechanism 13 to unreel the new material roll as an example: only the first mounting plate 120 is applied with a load moving towards the second mounting plate 130, so that the first mounting plate 120 drives the third mounting plate 140 to move synchronously, and the new and old material rolls form a correct posture at the splicing position for splicing.

On the contrary, when the first splicing mechanism 12 unwinds the new material roll and the second splicing mechanism 13 unwinds the old material roll, the second mounting plate 130 is applied with a load moving toward the first mounting plate 120, and the position adjustment of the new material roll and the old material roll at the splicing position is also easily accomplished.

In one possible embodiment, the discharge roller 14 is located below the first joining element 12 and the second joining element 13.

When the first pushing block 123 contacts the third mounting plate 140, the old material roll on the first splicing mechanism 12 between the first roller 121 and the discharging roller 14 is in a vertical state.

When the second pushing block 133 contacts the third mounting plate 140, the old material roll on the second belt splicing mechanism 13 between the second roller 131 and the discharging roller 14 is in a vertical state.

The above embodiment designs the positional relationship among the first push block 123, the second push block 133, and the third mounting plate 140. Taking the first splicing mechanism 12 to unreel the old material roll and the second splicing mechanism 13 to unreel the new material roll as an example, when a load is applied to the first mounting plate 120, so that the first mounting plate 120 moves towards the second mounting plate 130, when the first push block 123 contacts the third mounting plate 140, the fulcrum of the discharging passing roller 14 and the first passing roller 121 acting on the old material roll is on a vertical straight line, so that the pre-splicing part of the old material roll is in a vertical state, at this time, the relative positions of the first mounting plate 120 and the third mounting plate 140 are not changed, the load continues to drive the first mounting plate 120 and the third mounting plate 140 to move towards the second mounting plate 130, and finally, the old material roll passing through the roller 121 is attached to the new material roll passing through the roller 131, so that the old material roll is attached to the new material roll in a vertical state for splicing.

On the contrary, when the first splicing mechanism 12 unwinds the new material roll and the second splicing mechanism 13 unwinds the old material roll, the principle is as above, and the description is omitted here.

In a possible implementation manner, the automatic belt splicing apparatus 10 further includes a first driving cylinder 20 and a second driving cylinder 30, the first driving cylinder 20 is used for driving the first mounting plate 120 to move left and right, and the second driving cylinder 30 is used for driving the second mounting plate 130 to move left and right.

It should be noted that, in order to ensure that the first pushing block 123 and the second pushing block 133 can accurately contact the third mounting plate 140, in this embodiment, the third mounting plate 140 is rectangular, and the first pushing block 123 and the second pushing block 133 are T-shaped, so that when the first pushing block 123 and the second pushing block 133 contact the third mounting plate 140, a vertical contact surface exists.

second drive cylinders

20 and 30 provide a load to the first and second mounting

plates

In other embodiments, the first mounting plate 120 and the second mounting plate 130 can be driven to move left and right by other specific linear driving devices, such as a cylinder or a linear module.

In one possible implementation, the automatic belt splicing apparatus 10 further includes a first positioning cylinder 40 and a second positioning cylinder 50, and the first positioning cylinder 40 and the second positioning cylinder 50 are respectively located at two sides of the third mounting plate 140 and are connected to the third mounting plate 140.

When the third mounting plate 140 slides to adjust the splicing position of the new and old material rolls to the correct posture, the third mounting plate 140 is kept in the current position by arranging the first positioning cylinder 40 and the second positioning cylinder 50 on the two sides of the third mounting plate 140. The condition that the quality of the belt splicing is influenced by the deviation of the discharging roller 14 due to the influence of the tension of the material coil passing belt on the discharging roller 14 is avoided.

The first old material cutting mechanism 70 includes a first cutting cylinder 701, a first old material cutter 702 and a first old material suction cup 703, the first cutting cylinder 701 is disposed on the first mounting plate 120, the first old material suction cup 703 is disposed at an execution end of the first cutting cylinder 701 through a spring, and the first old material cutter 702 is disposed at an execution end of the first cutting cylinder 701. The first cutting cylinder 701 drives the first old material suction cup 703 and the first old material cutter 702 to solve the old material roll, and the old material roll is cut by the first old material cutter 702. Similarly, the second used material cutting mechanism 71 includes a second cutting cylinder, a second used material cutter and a second used material suction cup.

It should be noted that the automatic tape splicing apparatus 10 further includes an intermediate passing roller mounting plate 80, an intermediate passing roller 81, and a first unwinding passing roller 82a (a second unwinding passing roller 82b), the first unwinding passing rollers 82a are provided on the first mounting plate 120, and the second unwinding passing rollers 82b are provided on the second mounting plate 130. The intermediate roller mounting plate 80 is positioned between the first mounting plate 120 and the second mounting plate 130, and the intermediate rollers 81 are provided on the intermediate roller mounting plate 80. Taking the first splicing mechanism 12 for unwinding the old material roll and the second splicing mechanism 13 for unwinding the new material roll as an example, when the first mounting plate 120 approaches the second mounting plate 130, the old material roll at the first old material cutting mechanism 70 acts on the middle over roller 81, and the old material roll at the portion is supported by the first unwinding over roller 82a and the middle over roller 81, so that the first old material cutting mechanism 70 can easily cut the old material roll.

It should be noted that, taking the first splicing mechanism 12 unwinding the old material roll and the second splicing mechanism 13 unwinding the new material roll as an example, the working process of the automatic splicing device 10 provided in this embodiment is as follows:

before splicing, the old material roll passes through the first unwinding roller 82a and the first roller 121 of the first mounting plate 120, the new material roll passes through the second unwinding roller 82b and the second roller 131 of the second mounting plate 130, the new material roll cut by the second cutter 615 is pressed between the second clamping suction cup 613 and the second pressing block 611, the adhesive tape is manually attached to the diaphragm (the old material roll), and the release paper on the other side of the adhesive tape is torn off.

When the tape needs to be changed, the first driving cylinder 20 drives the first mounting plate 120 to move to the right side, and meanwhile, when the first pushing block 123 touches the third mounting plate 140, the discharging roller 14 is driven to move to the right side (at this time, the old material roll between the first roller 121 and the discharging roller 14 is in a vertical state), the first driving cylinder 20 continues to drive the first mounting plate 120 and the third mounting plate 140 to move, finally, the first roller 121 and the second roller 131 touch, and the new and old material tapes are vertically pasted together. Meanwhile, the second rubberizing cylinder 132a drives the second rubberizing suction cup 132c to rotate 90 degrees to stick the new material roll stuck with the gummed paper and the old material roll together. Meanwhile, the old material cutter 702 cuts off the old material tape, thereby completing the splicing efficiently. It should be noted that, when the first splicing mechanism 12 unwinds the new material roll and the second splicing mechanism 13 unwinds the old material roll, the principle is the same as above, and the description is omitted here.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
