Technical Field

The invention relates to the technical field of metal processing equipment, in particular to a waste coiled material winding machine.

Background

Metal profiles such as aluminum and steel produce a large amount of scrap during processing, including scrap coil stock. The waste coiled material is the redundant part cut off in the side cut technology in the metal processing process. If not discharged in time, or handled, the waste coil stack can cause significant interference to the production line and production flow.

In the prior art, the collection and cleaning automation degree of the waste coiled materials is low. Because the specification of coiled material is different, and the shape is different, and the waste material is difficult to realize artifical clearance, directly simply piles up the clearance waste material, and is inefficient.

In order to improve quality and reduce consumption, in the technical field of metal processing equipment, equipment capable of assisting in recovering metal cutting waste materials is urgently needed.

Therefore, the application provides an abandonment coiled material rolling machine. The waste materials generated in the processing process of the metal materials, particularly the aluminum materials, can be treated to facilitate the collection and transportation of the waste materials. The scheme solves the problems by the following technical points:

As described above, the present application provides a waste coil winder. The device mainly comprises a coiled material belt conveying channel with a feeding port and a discharging port, a pressing roller and a clamping mechanism. In practical use, after the waste aluminum strips are cut, the finished product parts of the aluminum materials are pulled elsewhere to be made into aluminum coils, and the waste aluminum strips are pulled from the feeding ports to enter the coiled material strip conveying channel of the device. The end of the waste web is secured to the spool by a clamp on the spool. Because the material pressing rollers and the material clamping mechanisms are arranged at intervals along the conveying direction of the coiled material belt, the material pressing rollers are positioned between the scroll and the feeding port. After the coiled material belt is straightened between the reel and the feeding port, the transmission mechanism is used for driving the material pressing roller to apply external force to the coiled material belt close to the abandoned coiled material belt, and the reel capable of rotating drives the abandoned coiled material belt to be wound. Because of the support of pressing the material gyro wheel and holding to compress tightly, abandonment coiled material area produces material deformation, and under the winding of spool drives, abandonment coiled material becomes the small-size waste material book that can keep comparatively permanent form. Subsequently, the spool is moved to be drawn out of the web transport path, or the web-like waste web dropped onto the spool is scraped using the moving shutter, and the formed, small-sized waste web is dropped and discharged from the discharge port. The aluminum material treated by the device has the advantages of more consistent size of waste materials, compact volume and easy collection and transportation for treatment.

The further technical scheme is as follows:

the waste coiled material winding machine also comprises a rack and two upright posts which are fixed at the top of the rack and vertically extend upwards, the arrangement direction of the two upright posts is perpendicular to the direction of the coiled material belt conveying channel, and the two upright posts are arranged at two sides of the coiled material belt conveying channel at intervals; the quantity of drive mechanism is two, locates two separately on the stand, two drive mechanism support jointly and press the material gyro wheel in the interval of two stands. The technical characteristics define the main structure of the winder. The frame extends in the horizontal plane and is the bearing foundation of the main structure body of the winding machine. The upright post which is fixedly arranged on the rack and extends upwards is mainly used for installing the pressing roller, and the pressing roller can move up and down under the driving of the transmission mechanism, so that the height difference between the upright post and the rack provides a movement space for the up-and-down movement of the pressing roller. In addition, the quantity of stand is two, and drive mechanism sets up respectively on two stands, and the drive mechanism on two stands respectively supports jointly and presses the material gyro wheel and reciprocate in the interval of two stands, and two drive mechanism drive jointly presses the material gyro wheel for press the motion of material gyro wheel more stable. Meanwhile, the coiled material belt conveying channel is arranged between the two stand columns, so that an operation area for the coiled material belt to deform by applying force to the coiled material belt by the pressing roller is also arranged between the two stand columns, the counter force generated by the pressing operation is uniformly borne by the two stand columns, and compared with the stand column, the use strength of the winding machine is improved by the arrangement of the two stand columns. And, two stand settings are in the both sides in operation district, and the respective shape size of two stands of reasonable setting can utilize the stand to enclose the operation district and close the isolation and become comparatively sealed solitary space according to actual behavior, avoids the external world to compress tightly the operation and produce the influence.

The transmission mechanism comprises a transmission cylinder, a swing rod and a roller supporting rod fixedly connected with the swing rod; the cylinder body of the transmission cylinder is rotatably arranged on the upright post through a cylinder hinged seat, the oscillating bar is rotatably arranged on the upright post through an oscillating bar hinged seat, and an expansion link of the cylinder is hinged with the oscillating bar to drive the oscillating bar to rotate; one end of the roller supporting rod is fixedly connected with the swing rod, and the other end of the roller supporting rod is connected with the pressing roller. The technical characteristics specifically limit the structure of the transmission mechanism and the connection relationship of the structures. The cylinder body of the cylinder drives the telescopic rod to stretch and retract so as to change the shape of the triangle, and the oscillating rod rotates relative to the oscillating rod hinge seat. As the swing rod swings, the roller supporting rod fixedly connected with the swing rod drives the pressing roller to move, and then the pressing roller is driven to move up and down. When the pressing roller does not work, the pressing roller is lifted, and when the pressing roller works, the pressing roller is pressed down again.

When the swing rod is located in the middle of the swing motion of the swing rod, the angle between the swing rod and the telescopic rod of the air cylinder is 90 degrees. The characteristic ensures that the swing motion track of the swing rod is regular and controllable.

The two material clamping mechanisms are symmetrically arranged on two sides of the coiled material belt conveying channel; the material clamping mechanism comprises a material clamping mechanism main body with a scroll and a material clamping movement mechanism for driving the material clamping mechanism main body to move horizontally, and the two scrolls of the two material clamping mechanisms can be butted or separated under the driving of the material clamping movement mechanism; and a material collecting port communicated with the discharge port is arranged right below the scroll. Under the drive of the material clamping movement mechanism, the two symmetrically arranged material clamping mechanisms are butted in the coiled material belt conveying channel, and coiled materials are wound on the two reels at the crossing and butting position. After the winding shaping operation was accomplished, two spools kept away from each other, and the waste material book falls down and falls into in the aggregate opening and then through this rolling machine of discharge gate discharge.

The material clamping movement mechanism comprises a material clamping cylinder and a cylinder guide rail, the main body of the material clamping mechanism is arranged on the material clamping cylinder in a bearing mode, and the cylinder guide rail is laid on the top of the rack. The technical characteristics limit the structural characteristics of the material clamping movement mechanism, and the material clamping cylinder and the cylinder guide rail drive the material clamping mechanism main body, so that the reaction is fast and the movement is stable.

In order to control the dropping position of the waste material roll, an air passage is arranged in the reel main body section, and a plurality of air suction ports communicated with the air passage are formed in the reel main body section. In particular, the abutment point of the two reels is located in the middle of the transport path of the web of material, and if not disposed of, the waste rolls tend to fall near the middle of the path after separation of the two reels. After the air suction port is arranged on the main body section of the scroll of the device, the air suction port of the scroll on one side of the moving target position of the waste roll is opened before the scroll is separated, so that the waste roll is tightly and firmly adsorbed on the scroll, then the two scrolls are separated, and when the material clamping mechanism on which the scroll is located moves to the position near the target position. The suction port stops sucking, and because the reel is not butted, a part of the waste coiled material is suspended at the moment, and under the action of gravity of the suspended section, the waste coiled material inclines and then falls to a target position.

In this technical characteristic, the induction port begins to extend from the joint of two reel sections, therefore, after the induction port adsorbs waste coiled material, the waste coiled material of keeping away from reel main part section is all unsettled from the joint of two reel sections, and the unsettled section length of waste coiled material is changeed the slope and is fallen. The air suction ports are all arranged on the same semi-arc surface of the scroll, so that resultant force of adsorption force generated by each air suction port faces to one direction, and the adsorption stability is improved.
