Description

Technical Field

[0001] The present invention belongs to the technical field of rolling equipment, and particularly relates to a rolling equipment for recycling waste metals. Background Art

[0002] When recycling and regenerating waste metal plates, it is usually necessary to level and straighten them through a rolling device for subsequent processing or direct utilization. Traditional rolling equipment applies pressure to the metal plate through one or more pairs of pressure rollers to eliminate its bending deformation and restore flatness. However, the rolling devices in the prior art still have significant defects when adapting to complex recycling scenarios, which are specifically manifested in the following two aspects: First, most existing rolling devices focus on the flattening function of metal plates, and the cutting process needs to rely on independent equipment such as shearing machines or laser cutting machines. Since the sizes of waste metal plates are different, they often need to be cut to a unified length after recycling to meet the requirements of standardized production. The traditional process requires the metal plate to be rolled first and then transported to the cutting station, resulting in a long production line, increased equipment investment, and easy occurrence of positioning errors in the connection of multiple processes, which is likely to cause uneven cutting lengths. Second, the thickness of waste metal plates varies greatly due to different sources. It is inconvenient to adjust the gap between the pressure rollers of existing rolling devices, and it is difficult to achieve dynamic and precise control during continuous feeding, and it cannot quickly adapt to metal plates of different thicknesses to ensure the rolling effect.

[0003] To solve the above problems, a rolling equipment for recycling waste metals is proposed in this application. Summary of the Invention

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. By arranging a rolling mechanism, the driving motor on the rolling mechanism can drive the first pressing roller to rotate. When the first pressing roller rotates, it can drive the second pressing roller to rotate synchronously through a chain-type linkage module. The first pressing roller and the second pressing roller cooperate to quickly flatten the metal plate. By rotating the adjusting screw rod, the lifting block can be controlled to lift, and the rolling gap between the first pressing roller and the second pressing roller can be adjusted, which is convenient for rolling plates with different thicknesses. By arranging a chain-type linkage module, transmission can be realized without affecting the adjustment of the rolling gap between the first pressing roller and the second pressing roller. Through the tension adjusting module, the tightness of the chain-type linkage module after the rolling gap is adjusted can be adjusted in real time, and dynamic precise control can be realized during continuous feeding, which can meet different rolling requirements and has good rolling effects.

[0021] 2. While the rolling mechanism is performing rolling treatment on the metal sheet, the second pressing roller on the rolling mechanism can drive the lower linkage mechanism to rotate through the transmission mechanism. The lower linkage mechanism can drive the upper linkage mechanism to rotate synchronously through the first linkage gear. When the upper linkage mechanism and the lower linkage mechanism rotate synchronously, the transmission cam can drive the upper cutting mechanism and the lower cutting mechanism to move relative to each other or move away from each other. When the cutting knife on the upper cutting mechanism moves to the lowest point under the drive of the transmission cam and the cutting knife on the lower cutting mechanism moves to the highest point under the drive of the transmission cam, the value detected by the displacement sensor reaches the maximum at this time. When the displacement sensor detects the set maximum value, the data processing and control module will control the upper and lower groups of cutting knives to punch once through the hydraulic rod, and the metal plate can be punched at equal lengths, which is convenient for subsequent recycling and reprocessing.

[0022] 3. The driving gear and the driven gear on the transmission mechanism are respectively fixedly installed at one end of the second pressing roller and one end of the lower linkage mechanism through the first fixing component and the second fixing component, which is convenient for disassembling and replacing the driving gear and the driven gear. By replacing the driving gear and the driven gear with different transmission ratios, the cutting length of the upper cutting mechanism and the lower cutting mechanism for the metal plate can be adjusted, and the metal plate can be cut into a unified length according to requirements, which can meet the needs of standardized production;

[0023] 4. By setting the guiding mechanism, the guiding roller on the guiding mechanism can guide and support the metal sheet after being rolled by the rolling mechanism, which can prevent the rolled metal sheet from being bent under its own gravity. The metal sheet can be limited by the annular limiting plate on the outer side of the guiding roller, which can prevent the metal sheet from shaking during transportation. After the metal sheet is cut by the upper cutting mechanism and the lower cutting mechanism, control the electric push rod on the guiding mechanism to contract. When the electric push rod contracts, it can drive multiple groups of guiding rollers to move synchronously towards the outside. When the guiding rollers move towards the outside to a certain extent, the cut metal sheet will fall into the storage box through the gap between the guiding rollers on the front and back sides for neat stacking, which is convenient for subsequent collection and processing.

By rotating the adjusting screw 202, the lifting of the lifting block 203 can be controlled, and the rolling gap between the first pressing roller 206 and the second pressing roller 207 can be adjusted, which is convenient for rolling plates with different thicknesses. The chain-type linkage module 208 can achieve transmission without affecting the adjustment of the rolling gap between the first pressing roller 206 and the second pressing roller 207.

[0057] As a further embodiment of the above invention: The displacement sensor 809 adopts a linear displacement sensor, and one end of it abuts against the cross plate 801.

[0058] As a further embodiment of the above invention: The transmission mechanism 10 includes a first fixing component 1001 and a second fixing component 1002 fixedly arranged at one end of the second pressing roller 207 and one end of the lower linkage mechanism 5 respectively. One end of the second pressing roller 207 is fixedly connected with a driving gear 1003 through the first fixing component 1001, and one end of the lower linkage mechanism 5 is fixedly connected with a driven gear 1004 through the second fixing component 1002.

By replacing the driving gear 1003 and the driven gear 1004 with different transmission ratios, the cutting length of the metal plate by the upper cutting mechanism 7 and the lower cutting mechanism 8 can be adjusted, and the metal plate can be cut into a unified length according to requirements, which can meet the needs of standardized production;

[0060] As a further embodiment of the above invention: The guiding mechanism 11 includes a rectangular plate member 1101 fixedly arranged on the top of the base 1 through a bracket. An L-shaped mounting member 1102 is fixedly arranged outside the rectangular plate member 1101. An electric push rod 1103 is fixedly arranged on the L-shaped mounting member 1102. A moving plate 1104 is fixedly arranged at one end of the electric push rod 1103. A plurality of push-pull rods 1105 are fixedly arranged at equal intervals on one side of the moving plate 1104. One end of the push-pull rod 1105 is rotatably connected with a guiding roller 1106 through a bearing. An annular limiting plate 1107 is fixedly arranged outside one end of the guiding roller 1106. The guiding roller 1106 on the guiding mechanism 11 can guide and support the metal plate after being roll-pressed by the roll-pressing mechanism 2, which can avoid the metal plate being bent under its own gravity after being roll-pressed. The annular limiting plate 1107 outside the guiding roller 1106 can limit the metal plate, which can avoid the metal plate shaking during transportation. After the metal plate is cut by the upper cutting mechanism 7 and the lower cutting mechanism 8, the electric push rod 1105 on the guiding mechanism 11 is controlled to contract. When the electric push rod 1105 contracts, it can drive a plurality of guiding rollers 1106 to move synchronously towards the outside. When the guiding rollers 1106 move towards the outside to a certain extent, the cut metal plate will fall into the storage box 12 through the gap between the guiding rollers 1106 on the front and back sides for neat stacking, which is convenient for subsequent collection and processing.

[0061] During specific implementation: The driving motor 205 on the rolling mechanism 2 can drive the first pressing roller 206 to rotate. When the first pressing roller 206 rotates, the second pressing roller 207 can be driven to rotate synchronously through the chain linkage module 208. The cooperation between the first pressing roller 206 and the second pressing roller 207 can quickly flatten the metal plate. By rotating the adjusting screw 202, the lifting block 203 can be controlled to lift or lower, and the rolling gap between the first pressing roller 206 and the second pressing roller 207 can be adjusted, facilitating the rolling treatment of plates with different thicknesses. The chain linkage module 208 can achieve transmission without affecting the adjustment of the rolling gap between the first pressing roller 206 and the second pressing roller 207. By controlling the electric telescopic rod 2092 on the tension adjustment module 209, the tension adjustment block 2093 can be moved left and right to adjust the position of the third sprocket 2084. By adjusting the position of the third sprocket 2084, the tightness of the chain linkage module 208 after the rolling gap is adjusted can be adjusted in real time. The tension sensor 2094 can detect the tension of the transmission chain 2085 on the chain linkage module 208, enabling dynamic and precise control during continuous feeding;

[0062] The second pressing roller 207 on the rolling mechanism 2 can drive the lower linkage mechanism 5 to rotate through the transmission mechanism 10. The lower linkage mechanism 5 can drive the upper linkage mechanism 4 to rotate synchronously through the first linkage gear 6. When the upper linkage mechanism 4 and the lower linkage mechanism 5 rotate synchronously, the upper cutting mechanism 7 and the lower cutting mechanism 8 can be driven to move relative to each other or away from each other through the transmission cam 403. When the cutting knife 805 on the upper cutting mechanism 7 moves to the lowest position driven by the transmission cam 403 and the cutting knife 805 on the lower cutting mechanism 8 moves to the highest position driven by the transmission cam 403, the value detected by the displacement sensor 809 reaches the maximum at this time. When the displacement sensor 809 detects the set maximum value, the data processing and control module will control the upper and lower groups of cutting knives 805 to punch once through the hydraulic rod 802, enabling equal-length punching of the metal plate;

[0063] The driving gear 1003 and the driven gear 1004 are respectively sleeved on the outer side of the threaded connection column, and then the anti-loosening nut is rotated to lock and fix the driving gear 1003 and the driven gear 1004, completing the installation. By replacing the driving gear 1003 and the driven gear 1004 with different transmission ratios, the cutting length of the upper cutting mechanism 7 and the lower cutting mechanism 8 for the metal plate can be adjusted, and the metal plate can be cut into a unified length according to requirements, meeting the needs of standardized production;

[0064] The guiding roller 1106 on the guiding mechanism 11 can guide and support the metal plate after being roll-pressed by the roll-pressing mechanism 2, which can prevent the roll-pressed metal plate from being bent under its own gravity. The annular limiting plate 1107 outside the guiding roller 1106 can limit the metal plate, which can prevent the metal plate from shaking during transportation. After the metal plate is cut by the upper cutting mechanism 7 and the lower cutting mechanism 8, the electric push rod 1105 on the guiding mechanism 11 is controlled to contract. When the electric push rod 1105 contracts, it can drive multiple groups of guiding rollers 1106 to move synchronously outward. When the guiding rollers 1106 move outward to a certain extent, the cut metal plate will fall into the storage box 12 through the gap between the guiding rollers 1106 on the front and rear sides for neat stacking.
