Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of machinery and relates to a color-coated plate rolling and cutting device. Background Art
[0002] Color-coated sheets are widely used in many fields such as construction, home appliances, and automobile manufacturing. In the production process of color-coated sheets, after a series of processes such as pre-treatment, powder coating, and curing, the continuous color-coated sheet strips need to be rolled into rolls for subsequent packaging, storage, and transportation. However, different end users or application scenarios have specific requirements for the length of color-coated sheets, which means that before or during rolling, the continuous color-coated sheets must be accurately cut at the specified length position.
[0003] The existing cutting and winding process is generally that the continuous color-coated plate passes through the cutting device and is continuously wound on the winding mechanism. When the color-coated plate is about to be wound to the required length, the cutting mechanism is operated, and the continuous color-coated plate is cut at the cutting mechanism and then transported to the winding mechanism for winding. In this process, especially in the transportation link from the cutting point to the winding mechanism, due to the release of the internal tension of the color-coated plate at the moment of cutting, the end of the color-coated plate after cutting may cause warping or rebound, which is not conducive to smooth winding and subsequent bundling and packaging, and may even cause safety hazards. Utility Model Content
[0004] The purpose of the utility model is to provide a safe, reliable and convenient color-coated plate rolling and cutting device for rolling and bundling in view of the above problems existing in the prior art.
[0005] The purpose of the utility model can be achieved through the following technical solutions:
[0006] A color-coated plate rolling and cutting device comprises a conveying platform and a rolling mechanism, and is characterized in that it also comprises a cutting mechanism and a pressing mechanism. The conveying platform and the rolling mechanism are arranged opposite to each other on the left and right, and the cutting mechanism and the pressing mechanism are both arranged above the conveying platform and the rolling mechanism. The cutting mechanism is located close to one side of the conveying platform and can be lowered to cut the color-coated plate. The pressing mechanism is located close to one side of the rolling mechanism and can be lowered to press the cut color-coated plate onto the rolling mechanism.
[0007] The color-coated plate winding and cutting device provides a stable carrier platform for the continuous conveyance of the color-coated plate through the setting of the conveyor table, ensures that the color-coated plate remains straight before being cut and provides support for the cutting action, and the setting of the cutting mechanism is used to accurately press down and cut the color-coated plate according to the winding length requirement, to ensure that the cut end surface is neat and burr-free, and the setting of the pressing mechanism presses down in time after the color-coated plate is cut, so that the cut end of the color-coated plate is flatly attached to the surface of the color-coated plate that has been wound on the winding mechanism, effectively preventing the end of the color-coated plate from warping or bouncing, and then the color-coated plate is rolled into a roll through the setting of the winding mechanism, and the winding process is guaranteed to be tight and flat with the assistance of the pressing component, which is convenient for the subsequent bundling and packaging of the color-coated plate rolls. The conveyor table and the winding mechanism are prior art and are not described here.
[0008] The above-mentioned color-coated plate winding and cutting device also includes a support frame, which is arranged between the conveying platform and the winding mechanism. The support frame is in an inverted U shape, and the above-mentioned cutting mechanism and pressing mechanism are both fixedly connected to the upper part of the U-shaped recess of the support frame.
[0009] The support frame provides stable support for the cutting mechanism and the pressing mechanism, and at the same time makes the cutting mechanism and the pressing mechanism suspended. When the color-coated plate does not need to be cut, the cutting mechanism and the pressing mechanism are retracted above the color-coated plate, without affecting the conveying and winding of the color-coated plate.
[0010] In the above-mentioned color-coated plate winding and cutting device, the pressing mechanism includes a cylinder 1, a connecting seat and a pressing roller. The cylinder 1 is fixedly connected to the support frame, the connecting seat is fixedly connected to the end of the piston rod of the cylinder 1, the connecting seat is in an inverted U shape, and the pressing roller is rotatably connected to the U-shaped notch of the connecting seat and can rotate circumferentially.
[0011] Cylinder 1 is used to drive the connecting seat and the pressure roller to do lifting and lowering movements. The connecting seat is used to bear the weight and movement of the pressure roller. After the cylinder drives the pressure roller to descend, the pressure roller can fit the surface of the color-coated plate and press it tightly against the winding mechanism to prevent the color-coated plate from warping or bouncing. When the winding mechanism rotates, the cut end of the color-coated plate can rotate freely according to the forward direction of the color-coated plate during the winding process without affecting the winding process, thereby ensuring the flatness and tightness of the color-coated plate winding, and facilitating subsequent bundling and packaging. When the color-coated plate is rolled up to the end and is just pressed by the pressure roller, it is completely rolled up, and then the operator bundles the color-coated plate on the winding mechanism. After bundling is completed, the cylinder 1 contracts to drive the pressure roller to rise and retract, and then the bundled color-coated plate roll on the winding mechanism can be unloaded and subsequently packaged.
[0012] In the above-mentioned color-coated plate winding and cutting device, the cutting mechanism includes a second cylinder and a cutter, the second cylinder is fixedly connected to the support frame, the cutter is fixedly connected to the end of the piston rod of the second cylinder and the end of the cutter is arranged vertically downward.
[0013] Cylinder 2 is used to drive the cutter to do lifting movement. When the color-coated plate needs to be cut, cylinder 2 drives the cutter to descend until the end of the cutter completely cuts off the color-coated plate. Then cylinder 2 contracts to drive the cutter to rise and retract.
[0014] In the above-mentioned color-coated plate winding and cutting device, the width of the cutter matches the width of the conveyor platform, and the width of the pressing roller is smaller than the width of the cutter.
[0015] The width of the cutter ensures that the cutter can cover the entire width of the color-coated plate conveyed by the conveyor table, thereby achieving one-time complete cutting of the color-coated plate, improving the cutting efficiency, cutting accuracy and flatness of the cut end surface of the color-coated plate. The width of the nip roller ensures that the color-coated plate can be prevented from warping or bouncing so that it can be rolled up smoothly and flatly. At the same time, the space left at both ends of the nip roller (i.e., both sides of the color-coated plate) makes it easy for operators to use strapping tape or rope to bundle the two ends of the color-coated plate roll after the color-coated plate is rolled up, which is convenient for subsequent handling, packaging and storage.
[0016] In the above-mentioned color-coated plate winding and cutting device, the pressing roller includes a central shaft and a pressing wheel, both ends of the central shaft are rotatably connected to the connecting seat, and the pressing wheel is fixedly connected to the central shaft and is arranged coaxially with the central shaft.
[0017] After the pressing roller is driven by the cylinder to descend, the pressing wheel can directly contact the color-coated plate and press the color-coated plate against the winding mechanism, effectively preventing the plate from warping and bouncing. Because the pressing roller is fixedly connected to the center shaft, and the center shaft is rotatably connected to the connecting seat, the pressing wheel and the center shaft can be driven to rotate when the color-coated plate continues to move forward. Such a structure takes into account the dynamic pressing requirements of the pressing material and the smooth contact during the transportation of the color-coated plate, ensuring the flatness and stability of the color-coated plate during the winding process, while avoiding scratches or damage to the surface of the color-coated plate.
[0018] In the above-mentioned color-coated plate rolling and cutting device, the number of the pressing wheels is several, and the several pressing wheels are evenly distributed along the axial direction of the central axis and there is a gap between two adjacent pressing wheels.
[0019] The gaps between the pressing wheels provide operating space for operators to bundle the color-coated coils after they are rolled up. Operators can pass strapping tape or rope through these gaps to firmly bundle the rolled color-coated coils, facilitating subsequent handling, packaging and storage.
[0020] In the above-mentioned color-coated plate rolling and cutting device, the number of the cylinders 2 is several, and the several cylinders 2 are evenly distributed along the width direction of the cutter.
[0021] Several cylinders synchronously drive the cutter to do lifting movement to ensure the balance of the cutter during the movement, thereby further improving the accuracy and flatness of the cutter's cutting of the color-coated plate.
[0022] Compared with the prior art, the color-coated plate winding and cutting device integrates the functions of conveying, cutting, pressing and winding, has a compact structure, and can improve production efficiency; the stable support of the color-coated plate by the conveying table and the one-time complete cutting of the cutting mechanism improve the cutting accuracy and cutting quality; the pressing mechanism can effectively press the cut color-coated plate to prevent warping or bouncing, which is safer and more reliable, while avoiding scratches or damage to the surface of the color-coated plate, ensuring the quality of the color-coated plate, and improving the flatness and tightness of the winding; and the structure of the pressing wheel makes it convenient for the operator to bundle the color-coated plate rolls after winding, which is convenient for subsequent handling, packaging and storage.
