Description

Technical Field

[0001] This utility model relates to the field of roll material production technology, and in particular to an automatic roll material feeding and cutting mechanism. Background Technology

[0002] In industrial production, the feeding and cutting of rolled materials are crucial steps in many processes. Traditional methods of feeding and cutting rolled materials often rely heavily on manual labor, which is not only inefficient but also prone to inaccurate cutting. For example, in some small processing plants, workers manually pull out the rolled material and cut it. This method is not only labor-intensive but also, due to the instability of manual operation, makes it difficult to ensure consistent length and precision in each cut, thus affecting product quality.

[0003] With the development of industrial automation, some automatic feeding and cutting equipment for rolled materials has gradually emerged; however, the existing equipment still has some shortcomings in practical applications: the ends of the rolled material will have a certain curvature during the winding and release process, which will lead to cutting difficulties or reduced cutting accuracy if not effectively limited. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing an automatic feeding and cutting mechanism for rolled materials.

[0005] The technical solution of this utility model is an automatic feeding and cutting mechanism for rolled materials, which includes a movable base frame, a unwinding roller, a traction device, a cutting device, and two sets of limiting plate assemblies. The mobile base is equipped with a roll unwinding bracket and a mounting bracket; the unwinding roller is rotatably mounted on the roll unwinding bracket; the traction device includes a first limiting roller, a second limiting roller, a servo motor roller frame, and a second servo cylinder. The first limiting roller is rotatably mounted on the mounting bracket, the servo motor is mounted on the mounting bracket and its output shaft is connected to the rotating shaft of the first limiting roller, the roller frame is slidably mounted on the mounting bracket, the second limiting roller is rotatably mounted on the roller frame, and the second servo cylinder is mounted on the mounting bracket and its output shaft is connected to the roller frame; two sets of limiting plate assemblies are symmetrically arranged below the first limiting roller and the second limiting roller. The limiting plate assembly includes a fixed limiting plate and a movable limiting plate. The fixed limiting plate is located above the movable limiting plate, and an elastic connecting assembly connects the fixed limiting plate and the movable limiting plate on the same side; the cutting device is located below the limiting plate assembly.

[0006] Preferably, the unwinding support is also equipped with an anti-deviation device, which includes a guide roller and two limiting rings. The guide roller is rotatably mounted on the unwinding support, and the two limiting rings are slidably sleeved on the outer periphery of the guide roller. The unwinding support is equipped with a drive assembly for driving the two limiting rings to move closer or further apart.

[0007] Preferably, the drive assembly includes a bidirectional lead screw and a knob. The bidirectional lead screw is rotatably mounted on the unwinding bracket, and the knob is located at the end of the bidirectional lead screw. Each of the two limit rings is connected to a connecting plate, and both connecting plates are threadedly connected to the bidirectional lead screw.

[0008] Preferably, the elastic connection assembly includes a guide rod, a spring, and a limiting block. A connecting frame is connected to the fixed limiting plate, the guide rod movably passes through the connecting frame and its two ends are respectively connected to the movable limiting plate and the limiting block, and the spring is sleeved on the guide rod.

[0009] Preferably, the cutting device includes a first servo cylinder, a cutter, and a cutter holder, wherein the cutter and the cutter holder are both located below the movable limiting plate, and the first servo cylinder is mounted on the mounting bracket and its output shaft is connected to the cutter.

[0011] Compared with the prior art, the present invention has the following beneficial technical effects: 1. The two sets of limiting plate components limit the ends of the roll material, preventing the roll material from being affected by the curvature of the ends. At the same time, when the cutter retracts, it can force the curled part at the bottom of the roll material to straighten, further improving the accuracy of cutting. 2. This continuous solution can achieve continuous segmented operation without stopping the machine, and has the advantages of simplified structure and high operating efficiency.

[0014] Example 1; as Figures 1-4 As shown, the automatic feeding and cutting mechanism for roll material proposed in this embodiment includes a movable base frame 1, an unwinding roller 3, a traction device, a cutting device, and two sets of limiting plate assemblies. The mobile base frame 1 is equipped with a roll unwinding bracket 2 and a mounting bracket 4; the unwinding roller 3 is rotatably mounted on the roll unwinding bracket 2; in this technical solution, a control panel 6 is also provided on the mounting bracket 4. The control panel 6 adopts a combination of HMI (Human Machine Interface) + PLC (Programmable Logic Controller). The HMI provides users with an intuitive and user-friendly operating interface, and various commands can be easily issued by touching the screen.

[0015] The traction device includes a first limiting roller 51, a second limiting roller 52, a servo motor 7, a roller frame 15, and a second servo cylinder 14. The first limiting roller 51 is rotatably mounted on the mounting bracket 4. The servo motor 7 is mounted on the mounting bracket 4 and its output shaft is connected to the rotating shaft of the first limiting roller 51. The roller frame 15 is slidably mounted on the mounting bracket 4. The second limiting roller 52 is rotatably mounted on the roller frame 15. The second servo cylinder 14 is mounted on the mounting bracket 4 and its output shaft is connected to the roller frame 15.

[0016] Two sets of limiting plate assemblies are symmetrically arranged below the first limiting roller 51 and the second limiting roller 52. The limiting plate assembly includes a fixed limiting plate 16 and a movable limiting plate 17. The fixed limiting plate 16 is located at the upper end of the movable limiting plate 17. The fixed limiting plate 16 on the side adjacent to the second limiting roller 52 is connected to the roller frame 15, and the fixed limiting plate 16 on the other side is connected to the mounting bracket 4. An elastic connecting assembly is connected between the fixed limiting plate 16 and the movable limiting plate 17 on the same side. The elastic connecting assembly includes a guide rod 191, a spring 192 and a limiting block 193. A connecting frame 18 is connected to the fixed limiting plate 16. The guide rod 191 movably passes through the connecting frame 18 and its two ends are connected to the movable limiting plate 17 and the limiting block 193 respectively. The spring 192 is sleeved on the guide rod 191.

[0017] The cutting device is located below the limiting plate assembly. The cutting device includes a first servo cylinder 13, a cutter 20, and a cutter holder 21. The cutter 20 and the cutter holder 21 are both located below the movable limiting plate 17. The first servo cylinder 13 is mounted on the mounting bracket 4 and its output shaft is connected to the cutter 20.

[0018] The working principle of this technical solution is as follows: The roll material is wound onto the unwinding roller 3. The end of the roll material is pulled out and passes through the area between the first limiting roller 51 and the second limiting roller 52. The roll material also needs to pass between the two sets of limiting plate assemblies. The pulling out of the roll material should be done with the help of auxiliary tools or machines, and safety should be taken into account. The second servo cylinder 14 is activated to drive the roller frame 15 and the second limiting roller 52 to move closer to the first limiting roller 51, giving the roll material a certain pressure. This pressure can ensure that the roll material remains stable during subsequent movement. When cutting the roll material, the servo motor 7 is activated to drive the first limiting roller 51 to rotate, thereby driving the roll material to move and realize the unwinding operation. When cutting the roll material, the first servo cylinder 13 is activated to drive the cutter 20 to move and insert into the groove of the cutter seat 21. At this time, the end of the roll material is cut off.

[0019] The purpose of the two sets of limiting plate assemblies in this technical solution is to limit the end of the rolled material being pulled out. Because the end of the rolled material has a certain curvature during the release process after winding, if the rolled material is not limited, it may lead to problems such as failure to cut the rolled material smoothly or a decrease in cutting accuracy. Since the cutting device is located at the bottom of the limiting plate assembly, the cutter 20 needs a certain amount of time to retract after completing the cut, but the unwinding of the rolled material is still ongoing. If the end of the rolled material is blocked by the cutter 20, the deformation generated by the end of the rolled material can push the movable limiting plate 17 to expand outward, thereby preventing the rolled material between the two sets of limiting plate assemblies from moving upward. When the cutter 20 retracts, the movable limiting plate 17 is driven to reset under the elastic force of the elastic connecting assembly. At this time, the curled part at the bottom of the rolled material is immediately forced to straighten, further improving the accuracy of the rolled material cutting.

[0020] Additionally, an inclined plate can be installed below the cutting device to allow the cut roll material to slide off automatically.

[0021] Example 2; as Figure 1 As shown, the automatic feeding and cutting mechanism for roll material proposed in this embodiment, compared with Embodiment 1, has an anti-deviation device installed on the roll material unwinding bracket 2. The anti-deviation device includes a guide roller 8 and two limiting rings 9. The guide roller 8 is rotatably mounted on the roll material unwinding bracket 2, and the two limiting rings 9 are slidably sleeved on the outer periphery of the guide roller 8. A driving assembly for driving the two limiting rings 9 to move closer or further apart is installed on the roll material unwinding bracket 2. The driving assembly includes a bidirectional lead screw 10 and a knob 11. The bidirectional lead screw 10 is rotatably mounted on the roll material unwinding bracket 2, and the knob 11 is located at the end of the bidirectional lead screw 10. A connecting plate 12 is connected to each of the two limiting rings 9, and the two connecting plates 12 are threadedly connected to the bidirectional lead screw 10.

[0022] In this embodiment, the operator can drive the bidirectional lead screw 10 to rotate by turning the knob 11. The rotation of the bidirectional lead screw 10 will cause the two limiting rings 9 to move closer or further apart. By adjusting the position of the two limiting rings 9, the position of the coil on the guide roller 8 can be restricted to prevent the coil from deviating during the unwinding process.

[0023] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
