Description

Technical Field

[0001] The utility model belongs to the technical field of metal drum rolling, and in particular relates to a metal drum rolling device which prevents cracking. Background Art

[0002] The metal drum rolling device is a mechanical device for rolling a metal sheet into a drum shape. Its technical background can be traced back to the demand for large-capacity storage, especially in the industrial field. Metal drums are widely used in storing liquids, powders, solid substances, etc., and are used in industries such as chemicals, food, medicine and petroleum. The existing metal drum rolling device mainly includes two rollers, which are located on both sides of the metal plate and driven to rotate by a motor. The metal plate is transmitted between the two rollers and compacted into a drum shape. However, the adjustment of the rolling force is a difficult task because the current devices often lack an effective control mechanism. Excessive rolling force may cause excessive force on the metal plate, thereby causing cracking and damage. This is mainly because the existing devices cannot accurately control the pressure between the rollers. When the pressure between the rollers is too large, the metal plate is prone to stress concentration, resulting in cracking. At the same time, excessive force on the metal plate can also cause other shape defects and deformation. Utility Model Content

[0003] In order to overcome the problem that the existing metal drum rolling device is difficult to adjust the rolling force, the metal plate coil is prone to cracking and damage due to excessive force.

[0004] The technical solution of the utility model is: a crack-proof metal drum rolling device, comprising a bracket, a bearing frame, a bearing frame, a side roller shaft, and a driving assembly; a bearing frame is arranged at the upper end of the bracket, and the bearing frame is fixedly connected to the bracket; an upper roller shaft assembly is arranged inside the bearing frame; side roller shafts are arranged at both front and rear ends below the upper roller shaft assembly, and the side roller shafts are connected to the bearing of the bearing frame; a driving assembly is arranged on one side of the bearing frame.

[0005] Preferably, the pressing distance between the upper roller and the side roller is adjusted by extending or retracting the output end of the pressure regulating cylinder to drive the adjustable bearing and the upper roller connected to it to descend or ascend, thereby adjusting the pressing strength of the plate coil. The height of the upper roller is adjusted by cooperating with an elastic transmission belt at the output end of the elastic drive motor, thereby solving the problem of the existing metal drum pressing device, which is difficult to adjust the pressing strength and easily causes the metal plate coil to be subjected to excessive force and prone to cracking and damage.

[0006] Preferably, the upper roller shaft assembly includes an upper roller shaft, an adjustable bearing, and a pressure regulating cylinder; the upper roller shaft is arranged between the bearing frames; adjustable bearings are arranged at both ends of the upper roller shaft, and the adjustable bearings are rotatably connected to the upper roller shaft bearings.

[0007] Preferably, a pressure regulating cylinder is provided at the upper end of the adjustable bearing, and the outer shell of the pressure regulating cylinder is fixedly connected to the upper end surface of the bearing frame, and the output end of the pressure regulating cylinder is transmission-connected to the outer shell of the adjustable bearing, and the height of the upper roller shaft is adjusted by extending or shortening the output end of the pressure regulating cylinder, thereby realizing the function of adjusting the pressing force of the plate roll.

[0008] Preferably, the drive assembly includes a transmission box, a transmission shaft, a transmission gear shaft, a driven gear shaft, and a drive motor; a transmission gear shaft is arranged inside the transmission box, and the transmission gear shaft is fixedly connected to one end of the outer side of the upper roller shaft assembly.

[0009] Preferably, a transmission shaft is provided at one outer end of the pressure regulating cylinder, and the transmission shaft is fixedly connected to the transmission gear shaft.

[0010] Preferably, a driving motor is arranged below the bearing frame, a housing of the driving motor is fixedly connected to the bracket, and an output end of the driving motor is connected to the transmission shaft via an elastic belt transmission.

[0011] Preferably, a driven gear shaft is arranged below both sides of the transmission gear shaft, and the driven gear shaft is fixedly connected to the side roller shaft, and the driven gear shaft is gear-connected to the transmission gear shaft. The output end of the elastic drive motor has an elastic transmission belt to realize the height adjustment of the upper roller shaft. When the upper roller shaft, the transmission gear shaft and the transmission shaft are raised, the thickness of the metal plate rolled on the upper roller shaft is used to squeeze the side roller shaft and drive it to rotate, thereby effectively improving the friction between the side roller shaft and the metal plate coil, and further improving the rotation efficiency of the plate coil during processing.

[0012] Beneficial effects of the utility model:

[0013] 1. The existing metal drum rolling device is difficult to adjust the rolling force, which easily causes the metal sheet coil to be subjected to excessive force and easy to crack and damage. The output end of the pressure regulating cylinder is extended and retracted to drive the adjustable bearing and the upper roller connected to it to descend or ascend to adjust the pressing distance between the upper roller and the side roller, thereby adjusting the pressing force of the plate coil. The elastic transmission belt at the output end of the elastic drive motor is used to adjust the height of the upper roller. When the upper roller, the transmission gear shaft, and the transmission shaft are raised, the thickness of the metal plate rolled on the upper roller is used to squeeze the side roller and drive it to rotate, thereby effectively improving the friction between the side roller and the metal sheet coil, thereby improving the rotation efficiency of the plate coil during processing. This solves the problem that the existing metal drum rolling device is difficult to adjust the rolling force, which easily causes the metal sheet coil to be subjected to excessive force and easy to crack and damage;

[0014] 2. By setting the upper roller assembly, the height of the upper roller can be adjusted by lengthening or shortening the output end of the pressure regulating cylinder, thereby realizing the function of adjusting the pressing force of the plate coil. BRIEF DESCRIPTION OF THE DRAWINGS
