[0002] In the field of metal processing, thin plate material is processed by stamping equipment, and the required shape material is punched out to process products, which will form long strip-shaped plate waste. These waste materials need to be wound and collected in time to avoid affecting the continuous operation of the stamping equipment.

[0003] For example, on August 9, 2019, a Chinese utility model patent with patent number ZL201821525326.6 and the name "a material guiding and waste winding device for metal sheet stamping" was published. It includes a material guiding device and a waste collecting device. The material guiding device is provided with a winding material cylinder wound with metal sheet. The metal sheet passes through the first guide roller into the material guiding roller. The material guiding roller delivers the metal sheet to the blanking die. The metal sheet is formed into waste after being punched by the blanking die. The waste is wound on the waste winding cylinder after passing through the material collecting roller and the second guide roller. The utility model automatically feeds the metal sheet after flattening by the material guiding roller, reducing the amount of manual labor. The waste is automatically wound on the waste winding cylinder, which is convenient for later processing and avoids the phenomenon of scattered waste accumulation. The device integrates the three processes of material guiding, stamping and waste collecting, and automatically produces, greatly reducing the amount of manual labor, saving labor cost and improving work efficiency. The device has low manufacturing cost and small floor area, and is suitable for small processing plants. However, this waste winding device uses a waste winding cylinder to wind the waste, which still has the following problems.

[0024] The utility model will be further explained in detail in connection with the drawings and specific embodiment.

[0025] Embodiment one, Figures 1 to 4 As shown in the drawings, a waste collecting device matched with a stamping device comprises a frame 1, a motor 2, a rotating shaft 3 pivoted on the frame 1, one end of the rotating shaft 3 connected with the rotating shaft of the motor 2 through a coupling 21, and a waste collector 4 connected with the other end of the rotating shaft 3. The waste collector 4 comprises four elastic clamping jaws 41, one end of each of the four elastic clamping jaws 41 connected with each other through a support 42, and each of the four elastic clamping jaws 41 arranged along the axial direction of the rotating shaft 3 and clamped on the outer circumferential surface of the other end of the rotating shaft 3. The four elastic clamping jaws 41 are used for winding long strip-shaped plate waste 10. When the pulling force generated by winding the long strip-shaped plate waste 10 is greater than the friction force between the four elastic clamping jaws 41 and the outer circumferential surface of the other end of the rotating shaft 3, the waste collector 4 can rotate relative to the rotating shaft 3. In this embodiment, a cylinder 31 is further fixedly connected with the other end of the rotating shaft 3, and the central axis of the cylinder 31 overlaps with the central axis of the rotating shaft 3. Each of the four elastic clamping jaws 41 is arranged along the axial direction of the rotating shaft 3 and clamped on the outer circumferential surface of the cylinder 31. When the pulling force generated by winding the long strip-shaped plate waste 10 is greater than the friction force between the four elastic clamping jaws 41 and the outer circumferential surface of the cylinder 31, the waste collector 4 can rotate relative to the cylinder 31. In this way, the weight of the rotating shaft 3 can be reduced, and sufficient friction force between the four elastic clamping jaws 41 and the outer circumferential surface of the cylinder 31 can be ensured.

[0026] The four elastic clamping jaws 41 are uniformly distributed along the circumferential direction of the rotating shaft 3.

[0027] A handle 43 is arranged on the support 42. The handle 43 is convenient for discharging the waste and mounting the waste collector 4 on the cylinder 31 at the other end of the rotating shaft 3. In addition, since the four elastic clamping jaws 41 are all elastic, the waste collector 4 can be easily separated from the long strip-shaped plate waste 10 wound in a roll shape, and the waste collector 4 can be reused.

[0028] A limiting baffle 5 is fixedly connected with the rotating shaft 3 near the elastic clamping jaws 41, and the limiting baffle 5 is perpendicular to the rotating shaft 3. The limiting baffle 5 can prevent the long strip-shaped plate waste 10 from running laterally and interfering with the frame 1.

[0029] The outer circumferential edge of the limiting baffle 5 is circular, the limiting baffle 5 is provided with a central through hole, and the limiting baffle 5 is sleeved on the rotating shaft 3 through the central through hole and fixedly connected with the rotating shaft 3.

[0030] By the setting of the support legs of the frame 1, after the frame 1 is installed on the horizontal ground, the central axis of the rotating shaft 3 is arranged to be inclined to the horizontal plane, and the end of the rotating shaft 3 connected to the motor 2 is lower than the other end of the rotating shaft 3 connected to the waste collector 4 (in this embodiment, the rotating shaft 3 is connected to the waste collector 4 through the cylinder 31). In this way, the collected roll-shaped long strip-shaped plate waste 10 is ensured to be close to one side of the limiting baffle 5 by the action of gravity, preventing the collected roll-shaped long strip-shaped plate waste 10 from being separated from the waste collector 4, and improving the use safety.

[0031] The frame 1 is provided with a start button 6 and an emergency stop button 7. When the start button 6 is pressed, the motor 2 starts to rotate. When the emergency stop button 7 is pressed, the motor 2 stops rotating.

[0032] In use, the long strip-shaped plate waste 10 output from the stamping equipment is clamped between one elastic clamp jaw 41 and the cylinder 31, and then the start button 6 is pressed. The motor 2 starts to rotate and drives the waste collector 4 to rotate through the rotating shaft 3. The long strip-shaped plate waste 10 intermittently output from the stamping equipment is wound on the waste collector 4. During the winding process, if the winding speed is faster than the output speed of the long strip-shaped plate waste 10, when the pulling force generated by the winding long strip-shaped plate waste 10 is greater than the friction force between the four elastic clamp jaws 41 and the outer circumferential surface of the cylinder 31 due to the pulling action, the waste collector 4 can rotate relative to the cylinder 31. In this way, the winding speed is reduced, the winding speed is automatically adjusted, the continuous work of the stamping equipment is not affected, and the waste collecting device can work better with the stamping equipment.

[0033] In actual work, the motor speed can be adjusted so that the winding speed of the waste collector 4 is slightly faster than the output speed of the long strip-shaped plate waste 10. The relative rotation of the waste collector 4 and the cylinder 31 automatically coordinates the speeds of the two.

[0034] When an abnormal situation occurs in actual work, the emergency stop button 7 can be pressed to stop the motor 2 from rotating, and the collecting device stops working. The emergency stop button 7 can also be linked with the stamping equipment, so that the stamping equipment also stops working, to improve the use safety of the equipment.

[0035] When the waste collector 4 winds waste to a certain amount or the stamping equipment no longer outputs long strip-shaped plate waste 10, the stamping equipment is first stopped, the tail of the long strip-shaped plate waste 10 is handled, the waste collector 4 with the wound long strip-shaped plate waste 10 is pulled out of the cylinder 31 through the handle 43, and then the waste collector 4 is separated from the roll-shaped long strip-shaped plate waste 10 after the roll-shaped long strip-shaped plate waste 10 is bound. The waste collector 4 is reloaded into the cylinder 31 to continue collecting waste.

[0036] Embodiment two, Figure 5As shown, different from the first embodiment is that the motor 2 shaft is connected to the rotating shaft 3 through a speed reducer 22. The frame 1 is provided with a controller 8, the motor 2 is a servo motor, and the controller 8 controls the rotating speed of the motor 2 according to the moving speed of the long strip-shaped plate waste output by the stamping device.

[0037] The frame 1 below the rotating shaft 3 is provided with an inductive switch 9, and when the inductive switch 9 senses that the long strip-shaped plate waste falls to a set position, the controller 8 increases the rotating speed of the motor 2.

[0038] The working mode of the embodiment is basically the same as the first embodiment, but the rotating speed of the motor 2 can be better controlled to better coordinate the working rhythm of the collecting device and the stamping device.

[0039] Although the utility model is specifically shown and introduced in combination with the preferred embodiment, it should be understood by those skilled in the art that various changes can be made to the utility model in form and details without departing from the spirit and scope of the utility model defined in the appended claims, and all are within the protection scope of the utility model.
