Description

TECHNICAL FIELD

[0001] The utility model relates to a slitting machine equipment field, concretely relates to a turnover type unwinding equipment for slitting machine. BACKGROUND

[0002] The slitting machine is a kind of slitting equipment for cutting wide film into multiple narrow materials.Currently, the unwinding equipment of slitting machine generally places the steel core of mother roll on guide rail, uses manpower to push the steel core to the position of specified chuck, and then clamps the two ends of mother roll steel core by two chucks. Many steps in the unwinding equipment of current slitting machine need to rely on manual carrying movement, which is inconvenient to operate, time-consuming and laborious, and affects production efficiency. Especially, for the winding of large-diameter and large-mass mother roll (the roll diameter of mother roll can reach 1.55 meters, and the weight can reach 3 tons), the operation is more difficult, and the labor intensity is large, time-consuming and laborious, which affects production efficiency. SUMMARY

[0003] The utility model aims at providing a turnover type unwinding equipment for slitting machine, which is convenient to operate, can realize automatic winding and unwinding, does not need worker's carrying during winding and unwinding process, thereby reducing labor intensity and improving production efficiency.

[0004] The technical scheme of the utility model is:

[0005] A turnover type unwinding equipment for slitting machine, comprising:

[0006] A rack;

[0007] An unwinding beam is rotationally arranged at the bottom of the rack, and the unwinding beam is provided with a guide rail parallel to the unwinding beam;

[0008] A beam driving mechanism drives the unwinding beam to rotate;

[0009] A pair of unwinding arms slide along the guide rail, each unwinding arm is provided with a rotary chuck, the rotary chucks on the pair of unwinding arms are coaxial and parallel to the guide rail, at least one unwinding arm in the pair of unwinding arms is provided with a chuck driving mechanism, and the chuck driving mechanism drives the corresponding rotary chuck to rotate;

[0010] A translation driving mechanism is arranged on the unwinding beam and drives the pair of unwinding arms to slide along the guide rail. The specific use of the turnover type unwinding equipment for slitting machine in the scheme is as follows,

[0011] When the mother roll is transported to the designated position in front of the rack, the beam driving mechanism drives the unwinding beam to rotate, so that the rotary chuck on the pair of unwinding arms is turned down to the designated position, and the rotary chuck is aligned with the position of the steel core of the mother roll. Then, the translation driving mechanism drives the pair of unwinding arms to slide along the guide rail, so that the rotary chucks on the pair of unwinding arms are close to each other, until the rotary chucks on the pair of unwinding arms clamp the two ends of the steel core of the mother roll. Then, the beam driving mechanism drives the unwinding beam to rotate, and the rotary chucks on the pair of unwinding arms drive the mother roll to turn up to the designated position, so that the automatic winding can be realized. After the material on the mother roll is completely released, the beam driving mechanism drives the unwinding beam to rotate, so that the rotary chucks on the pair of unwinding arms are turned down to the designated position, so that the automatic unwinding can be realized. The whole process does not need workers to carry, so it is convenient to operate, and the automatic winding and unwinding can be realized, and the workers do not need to carry during the winding and unwinding process, so as to reduce the labor intensity and improve the production efficiency.

[0012] Preferably, the beam driving mechanism comprises a pneumatic cylinder or an electric cylinder, one end of the pneumatic cylinder or the electric cylinder is hinged with the unwinding beam, and the other end of the pneumatic cylinder or the electric cylinder is hinged with the rack. In this way, the unwinding beam can be driven to rotate by the extension and contraction of the pneumatic cylinder or the electric cylinder, so that the rotary chucks on the pair of unwinding arms are turned down or up to the designated position.

[0013] Preferably, the pneumatic cylinder or the electric cylinder of the beam driving mechanism is arranged above the unwinding beam. Since the unwinding beam is arranged at the bottom of the rack, the pneumatic cylinder or the electric cylinder is arranged above the unwinding beam in this scheme. On the one hand, this facilitates the arrangement of the pneumatic cylinder or the electric cylinder. On the other hand, since the unwinding beam and the unwinding arms thereon need to be turned up by the beam driving mechanism to lift the mother roll up to the designated height position during the working process of the slitting machine, the height of the turning type unwinding equipment of the slitting machine should not be higher than the height of the mother roll lifted up to the designated position, so that the height space of the equipment site will not have higher requirements. Especially for the mother roll with large diameter (the diameter of the mother roll can reach 1.55 meters), the height of the highest point of the mother roll is generally not less than 2 meters during the working process of the slitting machine. Therefore, there is enough space above the unwinding beam to arrange the pneumatic cylinder or the electric cylinder of the beam driving mechanism, and the height of the equipment will not exceed the height of the mother roll lifted up to the designated position, that is, the height space of the equipment site will not have higher requirements.

[0014] Preferably, the distance between the rotary shaft of the unwinding beam and the rotary shaft of the rotary chuck is L1, the distance between the rotary shaft of the unwinding beam and the hinge shaft between the one end of the pneumatic cylinder or the electric cylinder and the unwinding beam is L2, and L1 is greater than L2. In this way, the pneumatic cylinder or the electric cylinder of the beam driving mechanism provides a smaller extension length, so that the mother roll can be lifted up to the designated height position, which can reduce the height space occupied by the pneumatic cylinder or the electric cylinder of the beam driving mechanism, reduce the height of the equipment, improve the compactness of the structure, and facilitate the transportation and entry and exit of the equipment.

[0015] As preferred, the translation driving mechanism corresponds to the unwinding arms one by one, and the translation driving mechanism comprises:

[0016] A screw rod mechanism, comprising a screw rod rotatably arranged on the unwinding beam and a nut matched with the screw rod, the screw rod being parallel to the guide rail, and the nut being connected with the corresponding unwinding arm;

[0017] A screw rod driving mechanism, comprising a driving motor for driving the screw rod to rotate. In this way, the corresponding unwinding arm can be driven to move individually by the translation driving mechanism, and the operation is more flexible.

[0018] As preferred, the translation driving mechanism comprises:

[0019] A screw rod mechanism, comprising a screw rod and two nuts corresponding to the unwinding arms one by one, the screw rod being rotatably arranged on the unwinding beam, the screw rod being parallel to the guide rail, the screw rod comprising two thread segments with opposite screw directions, and the nuts being connected on the thread segments one by one, and the nuts being connected with the corresponding unwinding arms;

[0020] A screw rod driving mechanism, comprising a driving motor for driving the screw rod to rotate. In this way, only one translation driving mechanism can be used to drive a pair of unwinding arms to approach each other, so as to clamp the two ends of the mother coil steel core by the rotary chuck; or to drive a pair of unwinding arms to separate from each other, so as to release the mother coil steel core; and the device can save one translation driving mechanism without affecting the normal operation of the device, thereby reducing the manufacturing cost.

[0021] As preferred, it further comprises a deviation rectifying driving mechanism, the rack comprises a base and an unwinding support, the base is provided with a sliding rail parallel to the unwinding beam, the unwinding support slides along the sliding rail, and the unwinding support is driven to slide along the sliding rail; the unwinding support comprises two side frames and a connecting beam connecting the two side frames, and the unwinding beam is rotatably arranged between the two unwinding side frames. In this way, when the rotary chuck on a pair of unwinding arms clamps the two ends of the mother coil steel core, the unwinding support can be driven to slide along the sliding rail by the deviation rectifying driving mechanism, so as to adjust the axial position of the mother coil and realize the axial deviation rectification of the mother coil.

[0022] As preferred, it further comprises a locking mechanism, which comprises:

[0023] A locking hole arranged on one end surface of the unwinding beam;

[0024] A locking pin slidingly arranged on the rack and matched with the locking hole;

[0025] A pneumatic cylinder arranged on the rack, for driving the locking pin to move so as to insert or remove the locking pin from the locking hole;

[0026] When the beam driving mechanism drives the unwinding beam to rotate, the rotating chuck on the unwinding arm is rotated to the position, at this time, the locking hole is aligned with the locking pin, and the locking pin is inserted into the locking hole by driving the locking pin to move.

[0027] As a preferred, the chuck driving mechanism comprises a chuck motor.

[0042] Specific embodiment one, as Figure 1 , Figure 2As shown in the figure, a kind of turnover unwinding equipment for slitting machine, including rack 1, unwinding beam 2, beam driving mechanism 3, a pair of unwinding arms 4 and translation driving mechanism 8.

[0043] Unwinding beam 2 is rotationally arranged at the bottom of rack 1. The rotation axis of unwinding beam 2 is parallel to unwinding beam 2. Guide rail 2.1 is arranged on unwinding beam 2. Guide rail 2.1 is parallel to unwinding beam 2. Beam driving mechanism 3 drives unwinding beam 2 to rotate.

[0044] A pair of unwinding arms 4 slide along guide rail 2.1. In this embodiment, a pair of unwinding arms 4 refers to two unwinding arms 4, and both of them slide along guide rail 2.1.

[0045] Translation driving mechanism 8 is arranged on unwinding beam 2, and it drives a pair of unwinding arms 4 to slide along guide rail 2.1. Translation driving mechanism 8 can drive a pair of unwinding arms 4 to approach or separate from each other.

[0046] Rotary chuck 5 is arranged on each unwinding arm 4. Rotary chuck 5 is rotationally arranged on unwinding arm 4 through bearing. The rotation axes of rotary chucks 5 on a pair of unwinding arms 4 are coaxial and parallel to guide rail 2.1, that is, the rotation axes of rotary chucks 5 on a pair of unwinding arms 4 are coaxial, and the rotation axes of rotary chucks 5 are parallel to guide rail 2.1. At least one unwinding arm 4 in a pair of unwinding arms 4 is provided with chuck driving mechanism 6. Chuck driving mechanism 6 drives corresponding rotary chuck 5 to rotate.

[0047] The specific use of a kind of turnover unwinding equipment for slitting machine in this embodiment is as follows,

[0048] When the mother roll is transported to the designated position in front of rack 1, beam driving mechanism 3 drives unwinding beam 2 to rotate, so that rotary chucks 5 on a pair of unwinding arms 4 are turned down to the designated position, and rotary chucks 5 are aligned with the position of the steel core of the mother roll. Then, translation driving mechanism 8 drives a pair of unwinding arms 4 to slide along guide rail 2.1, so that rotary chucks 5 on a pair of unwinding arms 4 approach each other, until rotary chucks 5 on a pair of unwinding arms 4 clamp the two ends of the steel core of the mother roll. Then, beam driving mechanism 3 drives unwinding beam 2 to rotate, and the mother roll is turned up to the designated position by rotary chucks 5 on a pair of unwinding arms 4, so that automatic winding can be realized. Finally, after the material on the mother roll is completely released, beam driving mechanism 3 drives unwinding beam 2 to rotate, so that rotary chucks 5 on a pair of unwinding arms 4 are turned down to the designated position, and then translation driving mechanism 8 drives a pair of unwinding arms 4 to slide along guide rail 2.1, so that rotary chucks 5 on a pair of unwinding arms 4 separate from each other, and the steel core is released, so that automatic unwinding can be realized. The whole process does not need workers to carry, so it is convenient to operate, and automatic winding and unwinding can be realized, and workers are not needed to carry during the process of winding and unwinding, so that the labor intensity is reduced and the production efficiency is improved.

[0049] Specific embodiment two is as follows, Figure 1 ,Figure 2 As shown, a flip-type unwinding device for a slitting machine includes a frame 1, an unwinding beam 2, a beam drive mechanism 3, a pair of unwinding arms 4, and a translation drive mechanism 8.

[0050] The unwinding beam 2 is rotatably mounted at the bottom of the frame 1. The rotation axis of the unwinding beam 2 is parallel to the unwinding beam 2. A beam drive mechanism 3 drives the unwinding beam 2 to rotate. The beam drive mechanism 3 includes a pneumatic cylinder or an electric cylinder. One end of the pneumatic cylinder or electric cylinder is hinged to the unwinding beam 2, and the other end of the pneumatic cylinder or electric cylinder is hinged to the frame 1. In this way, the unwinding beam 2 can be driven to rotate by the extension and retraction of the pneumatic cylinder or electric cylinder.

[0051] It should be noted that using a pneumatic or electric cylinder to extend and retract the unwinding beam 2 in the beam drive mechanism 3 is only a preferred embodiment. In actual manufacturing, the beam drive mechanism 3 can also use a power motor to drive the unwinding beam 2 to rotate.

[0052] The unwinding beam 2 is provided with a guide rail 2.1. Two slidingly connected slide blocks 2.2 are provided on the guide rail 2.1. The guide rail 2.1 is parallel to the unwinding beam 2. A pair of unwinding arms 4 slide along the guide rail 2.1. In this embodiment, a pair of unwinding arms 4 refers to two unwinding arms 4, both of which slide along the guide rail 2.1. Specifically, each unwinding arm 4 corresponds one-to-one with a slide block 2.2, and the unwinding arm 4 is fixed to the corresponding slide block 2.2 by bolts or welding, so that the unwinding arm 4 slides along the guide rail 2.1.

[0053] The translation drive mechanism 8 is mounted on the unwinding beam 2, and drives a pair of unwinding arms 4 to slide along the guide rail 2.1. The translation drive mechanism 8 can drive the pair of unwinding arms 4 to move closer to each other or separate from each other.

[0054] In one implementation, such as Figure 2 As shown, the translation drive mechanism 8 corresponds one-to-one with the unwinding arm 4. The translation drive mechanism 8 includes a lead screw mechanism 8.1 and a lead screw drive mechanism 8.2. The lead screw mechanism includes a lead screw rotatably mounted on the unwinding beam 2 and a nut that engages with the lead screw. The lead screw is parallel to the guide rail 2.1. The nut is connected to the corresponding unwinding arm 4; in this embodiment, the nut is connected to the slide 2.2 of the corresponding unwinding arm 4. The lead screw drive mechanism includes a drive motor that drives the lead screw to rotate. Thus, the corresponding unwinding arm 4 can be moved independently by the translation drive mechanism 8, making the operation more flexible. The drive motor and the lead screw are connected through a transmission mechanism, such as a synchronous belt drive mechanism or a gear drive mechanism. Of course, the drive motor can also directly drive the lead screw to rotate.

[0055] In another embodiment, a pair of unwinding arms 4 share a translation driving mechanism 8 (not shown in the figure). The translation driving mechanism 8 includes a screw rod mechanism and a screw rod driving mechanism. The screw rod mechanism includes a screw rod and two nuts corresponding to the unwinding arms 4. The screw rod is rotatably arranged on the unwinding beam 2. The screw rod is parallel to the guide rail 2.1. The screw rod includes two thread segments with opposite screw directions, and the nuts are correspondingly connected to the thread segments. The nuts are connected to the corresponding unwinding arms 4. In this embodiment, the nuts are connected to the sliding seats 2.2 of the corresponding unwinding arms 4. The screw rod driving mechanism includes a driving motor that drives the screw rod to rotate. In this way, only one translation driving mechanism 8 is needed to simultaneously drive a pair of unwinding arms 4 to move closer to each other, clamp the two ends of the mother roll steel core through the rotary chuck 5, or drive a pair of unwinding arms 4 to move away from each other to release the mother roll steel core. This can save one translation driving mechanism 8 and reduce production costs without affecting the normal operation of the equipment. The driving motor is connected to the screw rod through a transmission mechanism, such as a synchronous belt transmission mechanism or a gear transmission mechanism. Of course, the driving motor can also directly drive the screw rod to rotate.

[0056] As shown in Figure 1 , Figure 2 , each unwinding arm 4 is provided with a rotary chuck 5. The rotary chuck 5 is rotatably arranged on the unwinding arm 4 through a bearing. The rotary axes of the rotary chucks 5 on a pair of unwinding arms 4 are coaxial and parallel to the guide rail 2.1, i.e., the rotary axes of the rotary chucks 5 on a pair of unwinding arms 4 are coaxial, and the rotary axes of the rotary chucks 5 are parallel to the guide rail 2.1. At least one of the unwinding arms 4 in a pair of unwinding arms 4 is provided with a chuck driving mechanism 6. The chuck driving mechanism 6 drives the corresponding rotary chuck 5 to rotate.

[0057] In one embodiment, only one of the unwinding arms 4 in a pair of unwinding arms 4 is provided with a chuck driving mechanism 6. The chuck driving mechanism 6 includes a chuck motor. The chuck motor is connected to the rotary axis of the rotary chuck 5 through a transmission mechanism, such as a synchronous belt transmission mechanism or a gear transmission mechanism. Of course, the chuck motor can also directly drive the rotary chuck 5 to rotate.

[0058] In another embodiment, both unwinding arms 4 are provided with a chuck driving mechanism 6. The chuck driving mechanism 6 includes a chuck motor. The chuck motor is connected to the rotary axis of the corresponding rotary chuck 5 through a transmission mechanism, such as a synchronous belt transmission mechanism or a gear transmission mechanism. Of course, the chuck motor can also directly drive the corresponding rotary chuck 5 to rotate. In actual work, the chuck driving mechanisms 6 on a pair of unwinding arms 4 drive the rotary chucks 5 to rotate synchronously.

[0059] The specific use of the flip-type unwinding equipment of the slitting machine in this embodiment is as follows,

[0060] When the mother roll is transported to the designated position in front of the rack 1, the beam driving mechanism 3 drives the unwinding beam 2 to rotate, and the rotating clamping heads 5 on the pair of unwinding arms 4 are turned down to the designated position, so that the rotating clamping heads 5 are aligned with the position of the steel core of the mother roll.

[0061] Then, the translation driving mechanism 8 drives the pair of unwinding arms 4 to slide along the guide rail 2.1, so that the rotating clamping heads 5 on the pair of unwinding arms 4 are close to each other, until the rotating clamping heads 5 on the pair of unwinding arms 4 clamp the two ends of the steel core of the mother roll.

[0062] Then, the beam driving mechanism 3 drives the unwinding beam 2 to rotate, and the rotating clamping heads 5 on the pair of unwinding arms 4 drive the mother roll to turn up to the designated position, so that the automatic winding is realized. During the working process of the slitting machine, the clamping head driving mechanism 6 drives the rotating clamping heads 5 and the mother roll to rotate, and the material on the mother roll is output.

[0063] Finally, after the material on the mother roll is completely released, the beam driving mechanism 3 drives the unwinding beam 2 to rotate, and the rotating clamping heads 5 on the pair of unwinding arms 4 are turned down to the designated position, and then the translation driving mechanism 8 drives the pair of unwinding arms 4 to slide along the guide rail 2.1, so that the rotating clamping heads 5 on the pair of unwinding arms 4 are separated from each other, the steel core is released, and the automatic unwinding is realized. The whole process does not need workers to carry, so the operation is convenient, the automatic winding and unwinding can be realized, the workers do not need to carry during the winding and unwinding process, so the labor intensity is reduced, and the production efficiency is improved.

[0064] Specifically, as shown in Figure 1 , Figure 2 A turning type unwinding equipment for a slitting machine further comprises a guide roller 7. The guide roller 7 is rotationally arranged on the rack 1. The guide roller 7 is parallel to the rotating shaft of the rotating clamping head 5. The guide roller 7 is higher than the unwinding beam 2. In this embodiment, the guide roller 7 is the top of the rack 1. After the film of the mother roll is output, the guide roller 7 can guide.

[0065] In one embodiment of this embodiment, as shown in Figure 2 A turning type unwinding equipment for a slitting machine further comprises a deviation rectifying driving mechanism 9. The rack 1 comprises a base 1.1 and an unwinding support. The base 1.1 is provided with a sliding rail 1.4, which is parallel to the unwinding beam 2. The unwinding support slides along the sliding rail 1.4. The unwinding support comprises two side frames 1.2 and a connecting beam 1.3 connecting the two side frames 1.2. The unwinding beam 2 is rotationally arranged between the two unwinding side frames 1.2. The deviation rectifying driving mechanism 9 drives the unwinding support to slide along the sliding rail 1.4. The deviation rectifying driving mechanism 9 is a pneumatic cylinder, an oil cylinder or an electric cylinder. In this way, after the rotating clamping heads 5 on the pair of unwinding arms 4 clamp the two ends of the steel core of the mother roll, the unwinding support can be driven by the deviation rectifying driving mechanism 9 to slide along the sliding rail 1.4, so as to adjust the axial position of the mother roll and realize the axial deviation rectification of the mother roll.

[0066] In another embodiment of the present embodiment, the rack 1 comprises a base 1.1 and a unwinding support. The unwinding support comprises two side frames 1.2 and a connecting beam 1.3 connecting the two side frames 1.2. The side frames 1.2 of the unwinding support are directly fixed on the base 1.1 by bolts or welding. The unwinding beam 2 is rotatably arranged between the two unwinding side frames 1.2.

[0067] Further, as shown in Figure 1 , the cylinder or electric cylinder of the beam driving mechanism is arranged above the unwinding beam 2. Since the unwinding beam 2 is arranged at the bottom of the rack 1, the present scheme arranges the cylinder or electric cylinder above the unwinding beam 2, which on the one hand facilitates the arrangement of the cylinder or electric cylinder; on the other hand, since in the working process of the slitting machine, the unwinding beam 2 and the unwinding arm 4 thereon need to be driven by the beam driving mechanism 3 to be flipped upward to lift the parent roll to a specified height position, the height of the flip-type unwinding equipment of the slitting machine itself should not be higher than the height of the parent roll lifted to the specified position, so that the height space of the equipment site will not have higher requirements, especially for large-diameter parent rolls (the diameter of the parent roll can reach 1.55 meters), in the working process of the slitting machine, the height of the highest point of the parent roll is generally not less than 2 meters; therefore, there is enough space above the unwinding beam 2 to arrange the cylinder or electric cylinder of the beam driving mechanism 3, and arranging the cylinder or electric cylinder above the unwinding beam 2 will not make the equipment height exceed the height of the parent roll lifted to the specified position, that is, it will not have higher requirements on the height space of the equipment site.

[0068] Further, as shown in Figure 1 , the distance between the rotation axis of the unwinding beam 2 and the rotation axis of the rotary chuck 5 is L1, and the distance between the rotation axis of the unwinding beam 2 and the hinge shaft between one end of the cylinder or electric cylinder and the unwinding beam 2 is L2, and L1 is greater than L2. In this way, the cylinder or electric cylinder of the beam driving mechanism 3 provides a smaller extension length, that is, the parent roll can be lifted to a specified height position, which can reduce the height space occupied by the cylinder or electric cylinder of the beam driving mechanism 3, reduce the height of the equipment, improve the compactness of the structure, and facilitate the transportation and entry and exit of the equipment.

[0069] Further, the turnover unwinding equipment for slitting machine further comprises a locking mechanism. The locking mechanism comprises a locking hole, a locking pin slidingly arranged on the frame 1 and matched with the locking hole, and a cylinder arranged on the frame 1. The locking hole is arranged on one end surface of the unwinding beam 2. The sliding direction of the locking pin is parallel to the unwinding beam 2. The cylinder drives the locking pin to move so that the locking pin is inserted into or moved out of the locking hole. When the unwinding arm 4 is driven by the beam driving mechanism 3 to rotate, the rotary chuck 5 on the unwinding arm 4 is rotated to the position, at this time, the locking hole is aligned with the locking pin, and the locking pin is driven to move so that the locking pin is inserted into the locking hole. In this way, when the unwinding beam 2 is driven by the beam driving mechanism 3 to rotate, the parent roll is turned over to the specified position through the rotary chuck 5 on the pair of unwinding arms 4, and the locking pin is driven to move so that the locking pin is inserted into the locking hole, thereby locking the height position of the parent roll, ensuring the position stability of the parent roll in the working process of the slitting machine, and avoiding the change of the height position of the parent roll.

[0070] The above is only a preferred embodiment of the present application, and does not limit the present application. Any simple modification, change and equivalent transformation of the above embodiment according to the technical essence of the present application still belong to the protection scope of the technical scheme of the present application.
