DETAILED DESCRIPTION

[0047] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0048] like Figure 1~Figure 4 As shown, this embodiment proposes

[0049] A non-stop roll changing device comprises a main body 1; a cutting member 4 is arranged on the main body 1, and the cutting member 4 is used to cut the overlapping rolls A and B; a sticking roller 5 is slidably arranged on the main body 1, and the sticking roller 5 is used to stick an adhesive tape on the joint of the rolls A and B after sliding, and the cutting member 4 and the sticking roller 5 are arranged in sequence on the main body 1; a supporting member 6 is arranged on the main body 1, and the supporting member 6 is located at the lower side of the cutting member 4 and the sticking roller 5, and the supporting member 6 is used to guide the roll, and there is a gap between the supporting member 6 and the cutting member 4 and the sticking roller 5, and the gap is used for the roll to pass through.

[0050] In this embodiment, in order to solve the problem in the related art that the equipment needs to be stopped for loading and changing rolls, and the operation is cumbersome, a cutting piece 4, a material pasting roller 5 and a support member 6 are provided on the main body 1 for changing rolls without stopping the machine when the roll needs to be replaced. There is a gap between the cutting piece 4 and the material pasting roller 5 and the support member 6 for the roll to pass through. After the cutting piece 4 cuts the roll, the roll A and the roll B are still conveyed forward, and the cut material head is taken away. When the joint of the roll A and the roll B passes through the material pasting roller 5, the material pasting roller 5 slides close to the joint of the roll A and the roll B and sticks the joint of the roll A and the roll B together with tape. When changing rolls, the equipment does not need to be stopped, and the roll changing operation can be completed in the working state. The roll changing process does not affect the normal production of the equipment, and the operation is convenient and fast.

[0051] Specifically, the loading coil is coil A, and the prefabricated coil waiting to be loaded is coil B. Coil A and coil B pass through the gap between the cutting member 4 and the supporting member 6 together. When the die-cutting machine needs to change the roll, coil A and coil B are conveyed at the same time. The conveying speed of the conveying roller is kept the same as the working speed of the die-cutting machine. Coil A and coil B are conveyed at the same time. The cutting member 4 cuts the coil A and coil B below the cutting member 4. After cutting, the coil A located on the right side of the cutting member 4 and the coil B located on the left side of the cutting member 4 are docked together and conveyed synchronously. The remaining material heads of coil A and coil B are taken away. When the conveying coil A and coil B pass under the pasting roller 5, the pasting roller 5 slides toward the joint of coil A and coil B, and the tape on the pasting roller 5 sticks coil A and coil B together to complete the roll change. The supporting member 6 can prevent the coil from falling during the roll change process, and play a supporting and guiding role. The entire roll changing process does not require the equipment to stop, the die-cutting machine can continue production normally, and the operation is simple and convenient.

[0052] Furthermore, it also includes a discharge shaft 2, which is arranged on the main body 1; a conveying roller 3 is rotatably arranged relative to the main body 1, and the conveying roller 3 is located on one side of the cutting piece 4, and the conveying roller 3, the cutting piece 4 and the pasting roller 5 are arranged in sequence.

[0053] In this embodiment, by setting a discharge shaft 2 on the main body 1, it is convenient to discharge the coils A and B. By setting a conveying roller 3 above the support member 6, it is convenient to convey the coils A and B synchronously after cutting. Among them, the coil A located on the right side of the cutting member 4 can be conveyed forward by the die-cutting machine, and the coil B located on the left side of the cutting member 4 is conveyed synchronously with the conveying roller 3 and the coil A, so that the joint position of the coil A and the coil B reaches the bottom of the material attachment roller 5 at the same time. The rest of the coils can be directly taken away. After a roll change is completed, the staff can put the coil on the idle discharge shaft 2 when the equipment is working, and pass the starting position of the coil through the bottom of the conveying roller 3 and the cutting member 4 to facilitate the next roll change.

[0054] Furthermore, it also includes a screw 7, which is rotatably arranged on the main body 1; a guide member 8 is arranged on the main body 1; a sliding seat 9 is lifted and lowered on the guide member 8, the sliding seat 9 is threadedly connected to the screw 7, and the conveying roller 3 and the cutting member 4 are arranged on the sliding seat 9; a first driving member 10 is arranged on the main body 1, and the first driving member 10 is used to drive the screw 7 to rotate.

[0055] In this embodiment, in order to facilitate the completion of a roll change, when the staff pre-fabricates the roll on the unwinding shaft 2, the roll passes through the gap between the conveying roller 3 and the cutting member 4 and the support member 6, and the conveying roller 3 and the cutting member 4 are set on the sliding seat 9, and the screw 7 is driven to rotate by the first driving member 10. Since the sliding seat 9 is sleeved on the screw 7, under the guidance of the guide member 8, the sliding seat 9 can be raised and lowered relative to the main body 1, and the size of the gap between the conveying roller 3 and the cutting member 4 and the support member 6 can be changed during the lifting and lowering of the sliding seat 9. After the sliding seat 9 is raised, the gap becomes larger, which is convenient for the staff to pass the pre-fabricated roll through the gap. After the height of the sliding seat 9 is lowered, the gap becomes smaller, which is convenient for conveying the roll when changing the roll.

[0056] Furthermore, the support member 6 includes a plurality of rollers 12, which are rotatably arranged on the main body 1 and are respectively located below the corresponding positions of the conveying roller 3 and the cutting member 4; a support plate 11 is arranged on the main body 1, and is located below the material attaching roller 5, and one end of the support plate 11 is in contact with the roller 12.

[0057] In this embodiment, the support member 6 is composed of a roller 12 and a support plate 11. The roller 12 is located below the conveying roller 3 and the cutting member 4. Since the roller 12 is rotatably arranged, the roller 12 can rotate relative to the main body 1 during the conveying process of the conveying roller 3, and the conveying effect is better. When the cutting member 4 rotates and cuts, the roller 12 can also rotate relative to the main body 1 to avoid scratches on the surface of the support member 6 during cutting, which affects the flatness of the lower surface of the coil.

[0058] The support member 6 can also be directly composed of a support plate 11, which is located at the lower side of the conveying roller 3, the cutting member 4 and the material-attaching roller 5. While playing a supporting role to prevent the coil from falling, the support plate 11 has a simple structure and is more convenient to install.

[0059] Furthermore, the cutting member 4 comprises a rotating roller 13 , which is rotatably disposed on the sliding seat 9 ; and a cutting blade 14 is disposed on a side wall of the rotating roller 13 .

[0060] In this embodiment, the cutting member 4 includes a rotating roller 13 and a cutting blade 14. When the rotating roller 13 rotates, the cutting blade 14 rotates together with the rotating roller 13. When the cutting blade 14 contacts the coil, the coil can be cut. Since the cutting blade 14 has a certain height, during the process of the cutting blade 14 resetting after cutting, the rotating roller 13 will not contact the surface of the coil, and will not cause damage to the surface of the coil. Only the cutting blade 14 can cut the coil, which is easy to control.

[0061] Furthermore, it also includes a traction and pressing member 15, which includes a mounting seat 16, which is arranged on the main body 1, and the mounting seat 16 is located on the side of the material roller 5 away from the cutting member 4; the lifting seat 17 is slidably arranged on the mounting seat 16; the first telescopic member 18 is used to drive the lifting seat 17 to slide; the passive roller 19 is rotatably arranged on the lifting seat 17; the active pressure roller 20 is rotatably arranged on the mounting seat 16, and the support plate 11 is in contact with the active pressure roller 20; the second driving member 21 is arranged on the mounting seat 16, and the second driving member 21 is used to drive the active pressure roller 20 to rotate.

[0062] In this embodiment, the traction and pressing member 15 is located at the end of the material pasting roller 5 away from the cutting member 4, and can assist in conveying the cut coil. At the same time, when the joint of the coil passes through the traction and pressing member 15, the tape can be more firmly attached to the joint of the coil under the action of the traction and pressing member 15, so that the coil after the roll change can still be stably conveyed without breaking. The lifting seat 17 is slidably set on the mounting seat 16, and the lifting seat 17 can be driven to slide by the first telescopic member 18, so that the passive roller 19 is close to the active pressure roller 20, and the second driving member 21 drives the active pressure roller 20 to rotate, so as to press and convey the joints of the pasted coils. When the material is normally loaded after the pressing is completed, the first telescopic member 18 drives the lifting seat 17 to rise, and the distance between the passive roller 19 and the active pressure roller 20 becomes larger, which does not affect the normal loading.

[0063] Furthermore, there are multiple pasting rollers 5, and pasting rollers 5 are arranged on the upper and lower sides of the support plate 11. The support plate 11 has a notch 22 near the lower pasting roller 5. The lower pasting roller 5 is used to drive the tape to contact the joint of the rolls A and B through the notch 22 after sliding.

[0064] In this embodiment, a plurality of material pasting rollers 5 are respectively located on the upper side and the lower side of the support plate 11, and the support plate 11 has a notch 22 for the material pasting rollers 5 to pass through. The material pasting rollers 5 located on the upper side can drive the adhesive tape to adhere to the upper surface of the coil joint, and the material pasting rollers 5 located on the lower side can drive the adhesive tape to adhere to the lower surface of the coil joint after passing through the notch 22, so that the connection of the coil joint is more secure.

[0065] Furthermore, it also includes a tape material shaft 23, which has multiple tape material shafts 23. The multiple tape material shafts 23 are rotatably arranged on the main body 1. The tape material shafts 23 are located on the upper and lower sides of the multiple application rollers 5. The tape material shafts 23 are used to tension the tape together with the application rollers 5.

[0066] In this embodiment, the tape material shaft 23 and the material sticking roller 5 tension the tape together. The tape has the materials distributed at intervals. The material sticking roller 5 sticks the materials to the joints of the coiled material after sliding.

[0067] Furthermore, it also includes a tensioning roller 24, which has multiple tensioning rollers 24. The multiple tensioning rollers 24 are arranged on the main body 1, and the tensioning roller 24 is used to tension the coiled material; a receiving roller 25 is rotatably arranged on the main body 1, and the receiving roller 25 is used to tension the coiled material together with the tensioning roller 24 and the unwinding shaft 2.

[0068] In this embodiment, the prefabricated coil on the unwinding shaft 2 passes through the gap below the conveying roller 3 and the cutting member 4 and is connected to the receiving roller 25. After the roll change is completed, the receiving roller 25 can take up the head of the coil. The tensioning roller 24 can tension the coil to facilitate the conveyance of the coil when changing the roll.
