Description

Technical Field

[0001] The utility model relates to the technical field of material belt conveying, in particular to a new and old material belt conveying device. Background Art

[0002] In the models of printing, die-cutting, slitting and other industries, for the unwinding and rewinding of the coil, the conveying units of various parts of the machine need to cooperate with each other to make the coil run stably at a certain speed. When the old coil is about to run out, it is necessary to replace the old tape with a new tape. In order to ensure the alignment of the connection between the new tape and the old tape, the new tape and the old tape will be cut from the same position. The part of the material cut from the head of the new tape needs to be transported away by the new tape conveyor. In order to ensure that the production of the host is not affected during the material replacement process, the transportation of the old tape during the material replacement process requires an old tape conveyor with a cache function to be set downstream of the cutting position. However, the traditional method is to manually cut off a part of the material from the head of the new tape and discharge it. If the discharge is not timely, it will affect the subsequent production and processing of the tape. The host needs to stop or reduce the production speed to cooperate with the material replacement, which reduces the processing efficiency of the tape, so there are certain limitations.

[0003] Therefore, a new and old material belt conveying device is needed to solve the above problems. Utility Model Content

[0004] The utility model provides a new and old material belt conveying device, which realizes the automatic conveying of the new material belt and can cache the old material belt at the same time, thus avoiding the influence of the host machine slowing down or stopping when switching materials on the material belt processing efficiency.

[0005] The technical solution of the utility model is achieved in this way:

[0006] The new and old material belt conveying device includes a frame. Along the forward direction of the material belt, the frame is provided with a new material belt conveying component for conveying the new material belt and an old material belt conveying component for conveying the old material belt. The new material belt conveying component is arranged upstream of the old material belt conveying component. The new material belt conveying component includes a new material belt conveying roller and a traction rubber roller. The new material belt conveying roller is rotatably installed on the frame. A reset component for making the traction rubber roller always press against the new material belt conveying roller is arranged between the frame and the traction rubber roller. The old material belt conveying component includes a guide roller and an old material belt conveying roller. The guide roller is rotatably installed on the frame. The old material belt conveying roller is slidably installed on the frame. The extension line of the sliding direction of the old material belt conveying roller intersects with the extension line of the forward direction of the material belt.

[0007] As a preferred technical solution, the reset assembly includes a mounting plate, which is rotatably mounted on the frame via a hinge shaft, a rotating shaft is rotatably mounted on the mounting plate, the traction rubber roller is adjustably mounted on the rotating shaft, and a compression spring is arranged between the free end of the mounting plate and the frame.

[0008] As a preferred technical solution, a slide rail is provided on the frame, a slider is slidably installed on the slide rail, the old material belt conveyor roller is rotatably installed on the slider, a rodless cylinder is provided on the frame, and the slider is slidably installed on the frame through the rodless cylinder.

[0009] As a preferred technical solution, a drive motor is provided on the mounting plate, and the drive motor is drivingly connected to the rotating shaft.

[0010] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0011] The conveyor belt of old and new material comprises a conveyor belt of new material and a conveyor belt of old material, and the material head of new material is placed between the conveyor belt roller of new material and the traction rubber roller before changing materials. After the new material is cut, the rotating shaft rotates under the drive of the driving motor, driving the traction rubber roller to rotate. At this time, the material cut from the new material is squeezed by the conveyor belt roller of new material and the traction roller and rotated by the traction rubber roller, and the material cut from the new material can be conveyed away. During the material processing, the conveyor belt roller of old material moves in the direction away from the guide roller, that is, the old material is cached. During the material switching process, the conveyor belt roller of old material moves in the direction close to the guide roller, and the cached old material is conveyed downstream. In the utility model, the new material conveyor assembly is used to realize the automatic conveying of the new material, so as to avoid the influence of the untimely conveying of the new material on the subsequent production and processing of the material. At the same time, the old material conveyor assembly is used to realize the caching of the old material, so as to avoid the influence of the main machine speed reduction or shutdown on the material processing efficiency when switching materials.

[0012] Before switching materials, the new material belt conveying component can position the material head of the new material belt, so that the new material belt maintains a certain tension, preparing for the subsequent cutting of the new material belt. Therefore, the new material belt conveying component has the function of positioning the material head of the new material belt and conveying the new material belt at the same time, and has multifunctionality.

[0013] Since the new material belt conveying assembly includes a reset assembly, the traction rubber roller can be adjusted in position along the axial direction of the rotating shaft, so that it is suitable for material belts in various positions. Under the action of the compression spring, the traction rubber roller can press material belts of different thicknesses against the new material belt conveying roller, thereby increasing the usable range of the new material belt conveying assembly.

The new material belt conveying roller 2 is rotatably installed on the frame 1. A reset component for making the traction rubber roller 3 always lean against the new material belt conveying roller 2 is arranged between the frame 1 and the traction rubber roller 3. The old material belt conveying component includes a guide roller 4 and an old material belt conveying roller 5. The guide roller 4 is rotatably installed on the frame 1.

[0023] The method of using the utility model is as follows:

[0024] The first step is to place the head of the new material strip between the new material strip conveying roller 2 and the traction rubber roller 3 before switching the material. After the new material strip is cut, the traction rubber roller 3 rotates under the action of the drive motor 13, and the cut new material strip is conveyed away by the traction rubber roller 3, thus completing the conveyance of the cut new material strip.

[0025] In the second step, before switching the material, the old material belt conveying roller 5 is driven by the rodless cylinder 12 to move away from the guide roller 4, that is, the old material belt is buffered between the old material belt conveying roller 5 and the guide roller 4.

[0026] The third step is that during the material switching process, driven by the rodless cylinder 12, the old material belt conveyor roller 5 moves toward the direction close to the guide roller 4, and the cached old material belt moves forward along the forward direction of the material belt, so that the main machine can process without stopping.

[0027] In summary, the utility model realizes the automatic conveying of new material strips, and can also cache old material strips, thereby avoiding the influence of the host machine slowing down or stopping when switching materials on the material strip processing efficiency.
