[0035] The utility model proposes a reeling device 100, which is used for reeling a material strip. Figures 1 to 5 In an embodiment of the present invention, the unwinding device 100 includes two unwinding components 10 arranged at intervals, a glue splicing module 20 and a cutting knife component 30.

[0036] The glue connection module 20 includes two movably disposed glue connection seats 21 and two driving devices 22 . The two driving devices 22 are respectively connected to the corresponding glue connection seats 21 to drive each glue connection seat 21 to move toward or away from another glue connection seat 21 .

[0037] The driving device 22 has various types, such as a cylinder, a motor, etc., and specifically, a servo motor. The two driving devices 22 can simultaneously drive the two glue connection seats 21 to move closer to each other or farther away from each other, or one of the two driving devices 22 drives one glue connection seat 21 to move in a direction away from the other glue connection seat 21, and the other driving device 22 drives the other glue connection seat 21 to move in a direction close to the corresponding glue connection seat 21, that is, the two driving devices 22 drive the two glue connection seats 21 to move in the same direction.

[0038] In one example, the unwinding device 100 further includes a mounting frame 40, and the two glue connecting seats 21 are respectively movably mounted on the mounting frame 40. In another example, the unwinding device 100 further includes a housing, and the two glue connecting seats 21 are respectively movably mounted inside the housing. In another example, the two glue connecting seats 21 are movably mounted on a mounting plate of an automated production line.

[0039] Each glue connection seat 21 includes a rotatably arranged glue connection component 211 and a driving member 212. The circumferential sides of the glue connection component 211 are respectively provided with an adsorption surface 2115 and a glue sticking surface 2113. The driving member 212 is transmission-connected to the glue connection component 211 to drive the glue connection component 211 to rotate, so that the glue connection component 211 can switch the adsorption surface 2115 or the glue sticking surface 2113 toward the other glue connection seat 21.

[0040] The adsorption surface 2115 refers to one side surface of the adhesive bonding component 211, on which negative pressure is formed, and the adhesive bonding component 211 can adsorb the material tape by the negative pressure, and make the material tape close to the adsorption surface 2115. The adhesive bonding surface 2113 refers to the other side surface of the adhesive bonding component 211, on which an adhesive tape is provided, and the adhesive tape can be used to bond the broken parts of the material tape to connect the material tape together.

[0041] Among them, a glue changing channel is formed between the two glue connecting seats 21, and the two unwinding components 10 are used to carry the material tape roll and transport the material tape of the material tape roll to the glue changing channel. The glue changing channel is provided with a cutting station, and the cutter component 30 is used to cut the material tape at the cutting station.

[0042] The unwinding assembly 10 may include a rotating air expansion roller, and the material of the material roll is pulled and unwound by a driving motor outside the unwinding device. The unwinding assembly 10 may also include an unwinding roller with a power source. It can be understood that one of the two unwinding assemblies 10 is used to carry the working material roll, and the other unwinding assembly 10 is used to carry the spare material roll. Of course, the uses of the two unwinding assemblies 10 can be interchanged, that is, the unwinding assembly 10 used to carry the working material roll can also be used to carry the spare material roll.

[0043] In some examples, when the unwinding device 100 is in working state, when the working material tape roll is unwound to an empty roll, the adsorption surface 2115 located on one side of the working material tape adsorbs the working material tape and closely adheres to it, and at the same time, the adsorption surface 2115 located on the side of the spare material tape adsorbs the spare material tape and closely adheres to it, and then the cutter assembly 30 cuts the two material tapes in a direction perpendicular to the flow direction of the material tape at the cutting station, that is, the material tapes are cut on the adsorption surface 2115. At this time, the residual tailings can be recovered by reversing the unwinding assembly 10 for carrying the working material tape, or the negative pressure of the adsorption surface 2115 can be cut off, or the residual tailings can be dragged away by external force, and then the two adsorption surfaces 2 115 are in contact with each other, and at this time, the adsorption surface 2115 located on one side of the material tape can adsorb the end of the working material tape and the beginning of the spare material tape at the same time, that is, the adsorption surface 2115 originally located on one side of the working material tape can adsorb the end of the working material tape and the beginning of the spare material tape at the same time, and then cut off the negative pressure of the other adsorption surface 2115, and separate the two adsorption surfaces 2115 from each other, and finally drive the gluing component 211 without adsorbing the material tape to rotate through the driving part 212, switch the gluing surface 2113 to face the adsorption surface 2115 with the material tape adsorbed, and through the driving action of the driving device 22, face the adsorption surface 2115 with the material tape adsorbed, so as to complete the gluing operation.

[0044] Through the above technical scheme, the present application has the adsorption surface 2115 and the glue sticking surface 2113 of the glue connection assembly 211 in the two glue connection seats 21, which can be oriented toward the other glue connection seat 21, and can be driven by the driving device 22 to move toward the direction of the other glue connection seat 21. Under the mutual cooperation of the two glue connection seats 21, the adsorption surface 2115 of one glue connection seat 21 can be used to adsorb the end of the previous material belt and the beginning of the subsequent material belt together, and the driving member 212 of the other glue connection seat 21 can also be used to drive the glue connection assembly 211 to rotate, so that the glue sticking surface 2113 faces the adsorption surface 2115 with the material belt adsorbed, and is driven by the other driving device 22 to move toward the adsorption surface 2115 with the material belt adsorbed. The surface 2115 moves in the direction of the adhesive bonding work to complete the adhesive bonding work and realize the connection between the previous material strip and the subsequent material strip. In this way, the adsorption surface 2115 or the adhesive bonding surface 2113 can be switched to face the other adhesive connection seat 21 through the drive of the driving member 212, so as to facilitate the subsequent operation of the unwinding device 100. On the one hand, no manual operation is required, which avoids the problem of damage caused by manual operation of reel changing and improves the convenience and efficiency of material strip connection; on the other hand, there is no need to rely on the experience of workers to realize the connection of material strips, which reduces the influence of human factors, improves the connection accuracy and reliability of the previous material strip and the subsequent material strip, and indirectly improves the processing quality of the material strip by subsequent processing devices.

[0045] In some examples, such as Figures 1 to 4 As shown, the unwinding device 100 includes a mounting frame 40, and two driving devices 22 are respectively fixed to the mounting frame 40. The driving devices 22 can be installed on the mounting frame 40 by fixed connection methods such as threaded connection, welding, and riveting.

[0046] Each glue connection seat 21 also includes a base 213, which is movably mounted on the mounting frame 40 and is transmission-connected to a driving device 22 so as to move toward or away from another glue connection seat 21 under the drive of the corresponding driving device 22. The glue connection component 211 is rotationally mounted on the base 213, and the driving member 212 is fixedly mounted on the base 213 and is transmission-connected to the glue connection component 211 so as to drive the glue connection component 211 to rotate.

[0047] The glue joint assembly 211 can be rotatably mounted on the base 213 via a rotating shaft, a bearing, etc. The driving member 212 drives the glue joint assembly 211 to rotate relative to the base 213. During the rotation process, the circumference of the glue joint assembly 211 can adjust different sides to face another joint.

[0048] With such a configuration, the driving device 22 can drive the base 213 to move toward or away from another glue connection seat 21, thereby driving the glue connection assembly 211 rotatably mounted on the base 213 to move toward or away from another glue connection seat 21. When the adsorption surface 2115 faces another glue connection seat 21, under the driving action of the driving device 22, the glue connection assembly 211 can move toward another glue connection seat 21, and can adsorb the material strip through the adsorption surface 2115; when the glue sticking surface 2113 faces another glue connection seat 21, under the driving action of the driving device 22, the glue connection assembly 211 can move toward another glue connection seat 21, and can perform glue sticking operation on the material strip through the glue sticking surface 2113.

[0049] In some examples, such as Figures 1 to 4 As shown, each glue bonding component 211 includes a rotating member 2111 and an adsorption member 2112. The rotating member 2111 is rotatably installed on the base 213. The rotating member 2111 includes a first surface and a second surface. The first surface is adjacent to or opposite to the second surface. The glue surface 2113 is arranged on the first surface, and the adsorption member 2112 is installed on the second surface. The adsorption member 2112 is provided with an adsorption surface 2115 on the side away from the rotating member 2111.

[0050] Preferably, when the angle between the first surface and the second surface is 90°, the driving member 212 drives the rotating member 2111 to rotate 90°, so that the adsorption surface 2115 or the glue-applying surface 2113 can be switched to face the other glue-applying seat 21; when the first surface and the second surface are arranged opposite to each other, that is, the first plane and the second plane are parallel to each other, the driving member 212 drives the rotating member 2111 to rotate 180°, so that the adsorption surface 2115 or the glue-applying surface 2113 can be switched to face the other glue-applying seat 21.

[0051] With such arrangement, the driving member 212 can quickly drive the rotating member 2111 to rotate, so as to quickly switch the adsorption surface 2115 or the gluing surface 2113 toward the other gluing seat 21, so that the gluing component 211 can quickly complete the gluing operation, quickly connect the previous material strip and the subsequent material strip, and indirectly improve the processing efficiency of the subsequent processing device on the material strip.

[0052] In some examples, at least one adhesive bonding component 211 further includes an elastic member, an adsorbent 2112 is movably mounted on the second surface, and the elastic member is elastically supported between the adsorbent 2112 and the second surface. A guide column is protruding from the second surface, and the adsorbent 2112 is slidably mounted on an end of the guide column away from the second surface, and the number of the guide columns can be multiple.

[0053] With such arrangement, when the two adsorption surfaces 2115 squeeze and adsorb the material strip against each other, the elastic member can play a role of buffering and shock absorption to prevent the two adsorption members 2112 from having a hard collision and damaging the material strip, the adsorption surfaces 2115 , etc.

[0054] In some examples, such as Figure 3 As shown, an adsorption member 2112 includes two adsorption plates 2114, and the two adsorption plates 2114 are elastically mounted on the second surface through elastic members and are spaced apart along the width direction of the second surface. The cutter assembly 30 is fixedly mounted on the second surface and is located between the two adsorption plates 2114, so that when the two adsorption surfaces 2115 are squeezed against each other, the cutter assembly 30 protrudes between the two adsorption plates 2114 and cuts the material strip.

[0055] With such arrangement, when the two adsorption surfaces 2115 are pressed against each other, the cutter assembly 30 can cut the material strip between the two adsorption plates 2114. Thus, the structure of the cutter assembly 30 is simple, which not only saves the space for installing the cutter assembly 30, but also allows the adsorption surface area 2115 of the previous material strip and the subsequent material strip on the adsorption surface 2115 to be equal, thereby improving the stability of the unconnected material strip and facilitating the gluing operation.

[0056] In some examples, such as Figure 4 As shown, the other adsorption member 2112 is provided with a knife avoidance groove corresponding to the cutter assembly 30, so as to accommodate part of the blade of the cutter assembly 30 when the two adsorption surfaces 2115 are pressed against each other.

[0057] In some examples, such as Figure 1 and Figure 2 As shown, the mounting frame 40 is provided with a guide rail, which is extended in a direction perpendicular to the glue changing channel, and the base 213 of each glue connecting seat 21 is slidably mounted on the guide rail.

[0058] With such a configuration, the driving device 22 can drive the base 213 to slide along the guide rail, thereby driving the glue-joining assembly 211 mounted on the base 213 to move along the guide rail toward or away from the other glue-joining seat 21, so that the glue-joining seat 21 moves more smoothly relative to the mounting frame 40. The two driving devices 22 can simultaneously drive the two bases 213 to slide along the guide rail, so that the adsorption surfaces 2115 on the two glue-joining assemblies 211 contact or separate from each other.

[0059] In some examples, such as Figures 1 to 5 As shown, the unwinding device 100 further includes two tape-threading modules 50, each tape-threading module 50 includes a movably arranged tape-threading rod 51 and a driving structure 52, and the driving structure 52 is in transmission connection with the tape-threading rod 51 to drive the tape-threading rod 51 to move relative to the glue splicing module 20, and to pull the material tape to the adsorption surface 2115 through the tape-threading rod 51. The tape-threading rod 51 can fix the head end of the rear material tape by clamping, adsorption, gluing, etc.

[0060] With such an arrangement, the threading rod 51 can be used to pull the end of the rear material belt to the adsorption surface 2115 to improve the degree of automation of the unwinding device 100. In this way, not only the roll changing efficiency of the unwinding device 100 can be improved, but also the influence of human factors can be reduced. Specifically, the material belt is pulled to the adsorption surface 2115 by the threading rod 51, which avoids the inconvenience of manual threading, optimizes the process of the unwinding device 100, reduces the defective rate caused by manual threading, and avoids problems such as injuries caused by personnel threading.

[0061] In some examples, please refer to the above content. When the unwinding device 100 is in working state, when the working material tape roll is unwound to an empty roll, the adsorption surface 2115 located on one side of the working material tape adsorbs the working material tape and adheres to it. At the same time, the tape threading rod 51 pulls the spare material tape to the other adsorption surface 2115 and adheres to the adsorption surface 2115. Then, the two adsorption surfaces 2115 are driven to squeeze each other. The cutter assembly 30 can cut the material tape between the two adsorption plates 2114, and then drive the two adsorption surfaces 2115 to separate from each other. At this time, the residual tailings are recovered. , and then drive the two adsorption surfaces 2115 to contact each other, so that one adsorption surface 2115 can adsorb the end of the working material belt and the beginning of the spare material belt at the same time, and then cut off the negative pressure of the other adsorption surface 2115, so that the two adsorption surfaces 2115 are separated from each other, and finally the driving part 212 drives the gluing component 211 without adsorbing the material belt to rotate, and switches the gluing surface 2113 to face the adsorption surface 2115 with adsorbing the material belt, and through the driving action of the driving device 22, it faces the adsorption surface 2115 with adsorbing the material belt to complete the gluing operation.

[0062] In some examples, such as Figure 1 , Figure 2 and Figure 5 As shown, each belt threading module 50 also includes a conveying member 53, and the belt threading rod 51 is movably mounted on the mounting frame 40 through the conveying member 53. The conveying member 53 has a preset trajectory, and the preset trajectory flows through the glue changing channel. The driving structure 52 is transmission-connected with the conveying member 53 to drive the belt threading rod 51 to move along the preset trajectory through the conveying member 53.

[0063] The conveyor 53 includes but is not limited to a synchronous belt, a synchronous chain, a belt, etc. The conveyor 53 is movably mounted on the mounting frame 40 through a driven tooth. In this way, the conveyor 53 can pull the material belt to the adsorption surface 2115 through the belt threading rod 51 during the movement along the preset track.

[0064] In some examples, such as Figure 1 , Figure 2 and Figure 5As shown, the driving structure 52 includes a driving rod 54, one end of which is transmission-connected to the conveying member 53, and the other end of the driving rod 54 is provided with a driving handle 55. With such a configuration, after the head end of the rear material belt is fixed to the belt threading rod 51, the belt threading rod 51 can be driven to move along a preset trajectory by operating the driving handle 55.

[0065] In some examples, the driving structure 52 includes a driving motor, and the output end of the driving motor is in transmission connection with the conveying member 53. In this way, after the head end of the rear material belt is fixed to the belt threading rod 51, the driving motor can drive the belt threading rod 51 to move along a preset track, further improving the automation degree of the unwinding device 100.
