[0017] 3. This type of calendering equipment can move the lower movable block upward and fit with the upper movable block after the plate flat block is triggered by the protrusion on the plate surface, releasing the restriction of the movable block buckle on the upper movable block. Then the transmission mechanism can drive the upper movable block to descend and drive the plate flat block to perform the stamping operation. After the stamping is completed, the transmission mechanism drives the upper movable block to rise and re-engage with the movable block buckle, so that the plate stamping mechanism can quickly perform the next automatically triggered plate stamping operation after each stamping is completed.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] As introduced in the background technology, there are deficiencies in the existing technology. In order to solve the above technical problems, this application proposes a calendering device and a calendering method for metal sheet processing.

[0022] Example 1: See also Figures 1-8 , a calendering equipment, including a driving motor 1, a driving table 2, a device main body 4, a first calendering mechanism 6, a second calendering mechanism 7, a transmission mechanism 8 and a plate leveling mechanism 9, the driving table 2 is installed on the top of the driving motor 1, the device main body 4 is installed on one side of the driving table 2, a turntable 5 is installed inside the device main body 4, the first calendering mechanism 6 and the second calendering mechanism 7 are installed on the top of the device main body 4, the transmission mechanism 8 and the plate leveling mechanism 9 are installed on the top of the device main body 4, the power end of the driving motor 1 passes through the driving table 2 and is fixedly connected to the driving gear 3, the turntable 5 is fixedly installed inside the device main body 4, and one side of the transmission mechanism 8 is transmission-connected to the plate leveling mechanism 9; The driving end of the driving motor 1 can drive the driving gear 3 to rotate synchronously. When the driving gear 3 rotates, it can drive the first rolling mechanism 6 and the second rolling mechanism 7 to rotate synchronously to perform the rolling operation; The first calendering mechanism 6 includes a movable roller frame 62 and a first upper roller 64. The movable roller frame 62 is plugged into the device body 4. The first upper roller 64 is rotatably mounted on the inner side of the movable roller frame 62. During rolling, the aluminum alloy sheet is first rolled inside the first rolling mechanism 6 and then passes through the turntable 5 to enter the second rolling mechanism 7 for secondary rolling. When harder impurities appear in the sheet during rolling by the first rolling mechanism 6, the position of the first upper roller 64 rises and drives the movable roller frame 62 of the first upper roller 64 to rise, causing a bulge to appear on the top of the sheet. The sheet with the bulge on the top can touch the sheet leveling mechanism 9 when passing through the turntable 5. After the sheet leveling mechanism 9 is touched, the second rolling mechanism 7 rotates and can drive the sheet leveling mechanism 9 through the transmission mechanism 8 to flatten the impurities raised on the sheet, and then the sheet enters the second rolling mechanism 7 for a second rolling.

[0023] During operation, if there are no impurities in the aluminum alloy sheet, the sheet is first rolled from the inside of the first rolling mechanism 6 and then passes through the transfer table 5 to enter the inside of the second rolling mechanism 7 for secondary rolling. If there are impurities in the sheet, when the first rolling mechanism 6 is rolling, when harder impurities appear in the sheet, the position of the first upper roller 64 rises and drives the movable roller frame 62 to rise, so that a bulge appears on the top of the sheet, and the bulge on the top can touch the sheet flattening mechanism 9 when passing through the transfer table 5. After the sheet flattening mechanism 9 is touched, the second rolling mechanism 7 rotates and can pass through the conveyor The structure 8 drives the plate leveling mechanism 9 to flatten the raised impurities on the plate, and then the plate enters the second rolling mechanism 7 for a second rolling, so that the first upper roller 64 rises when the plate passes through the first rolling mechanism 6, so that the harder impurities remain on the surface of the plate to form harder protrusions. The protrusions on the surface of the plate can trigger the plate leveling mechanism 9 to flatten the harder impurities on the plate, and then the surface of the plate is flattened by the second rolling mechanism 7, so as to prevent the harder impurities from damaging the roller surface during the rolling process, thereby ensuring the quality of metal rolling.

[0024] The difference from the above embodiment is that, please refer to Figures 1-4 The first calendering mechanism 6 includes a first lower roller 61 and a movable roller frame 62. The first lower roller 61 is rotatably mounted inside the device body 4. A roller insert 63 is fixedly connected to the bottom of the movable roller frame 62. A first upper roller 64 is rotatably mounted inside the movable roller frame 62. A first roller gear 65 is fixedly connected to one side of the first upper roller 64. The outer portion of the first roller gear 65 is transmission-connected to the drive gear 3 via a first roller chain 66. When the driving motor 1 rotates, it can drive the driving gear 3 to rotate. When the driving gear 3 rotates, it can drive the first roller gear 65 to rotate through the first roller chain 66. When the first roller gear 65 rotates, it can drive the first upper roller 64 to rotate. When the first upper roller 64 rotates, it can drive the plate to be rolled. The movable roller frame 62 is connected to the interior of the device body 4 through the roller plug block 63. The movable roller frame 62 can move up and down inside the device body 4. When impurities appear in the rolled plate, the movable roller frame 62 can move up and down to adjust the distance between the first upper roller 64 and the first lower roller 61.

[0025] The second calendering mechanism 7 includes a second lower roller 71 and a second upper roller 72. The second lower roller 71 and the second upper roller 72 are both rotatably mounted inside the device body 4. The two ends of the second upper roller 72 are fixedly connected to a second roller gear 73 and a roller transmission gear 75 respectively. The outer portion of the second roller gear 73 is transmission-connected to the driving gear 3 via a second roller chain 74. When the driving motor 1 rotates, it can drive the driving gear 3 to rotate. When the driving gear 3 rotates, it can drive the second roller gear 73 to rotate through the second roller chain 74. When the second roller gear 73 rotates, it can drive the second upper roller 72 to rotate. When the second upper roller 72 rotates, it can drive the plate to be rolled for the second time and drive the roller transmission gear 75 to rotate.

[0026] During operation, the driving motor 1 can drive the first upper roller 64 and the second upper roller 72 to rotate synchronously. When the plate is processed, it is first rolled by the first rolling mechanism 6. When impurities appear in the plate during the rolling process, the first upper roller 64 can move upward to prevent the harder impurities in the plate from damaging the roller surface. After the processing is completed by the first rolling mechanism 6, the plate is rolled for the second time by the second rolling mechanism 7, which can prevent damage to the rollers while ensuring the rolling quality.

[0027] The difference from the above embodiment is that, please refer to Figure 4-Figure 8 The transmission mechanism 8 includes a rotating fixed pile 81, which is fixedly installed on the top of the device body 4. A transmission shaft 82 is rotatably installed inside the rotating fixed pile 81, and one end of the transmission shaft 82 is fixedly connected to a transmission gear 83. The outside of the transmission gear 83 is transmission-connected to the roller transmission gear 75 through a transmission chain 84. A block slide 85 is provided at the other end of the transmission shaft 82, and a block spring 86 is fixedly installed inside the block slide 85. The movable end of the block spring 86 is fixedly connected to a rotating block 87. One end of the transmission shaft 82 with a block slide 85 is rotatably connected to a transmission warehouse 88, and a fixed block 89 is fixedly installed inside the transmission warehouse 88. A transmission turntable 810 is fixedly connected to one side of the fixed block 89, and a transmission turntable 810 has a transmission block 811 fixedly installed on the side thereof. When the roller transmission gear 75 rotates, it can drive the transmission gear 83 to rotate synchronously through the transmission chain 84. When the transmission gear 83 rotates, it can drive the transmission shaft 82 to rotate synchronously.

[0028] The end of the transmission shaft 82 is engaged with the fixed block 89 inside the transmission chamber 88 through the fixed block 89. When the rotating block 87 is engaged with the fixed block 89, the transmission shaft 82 rotates to synchronously drive the transmission chamber 88 to rotate. When the transmission chamber 88 rotates, the transmission turntable 810 can be driven to rotate. The rotating block 87 is slidably installed inside the block slot 85 through the block spring 86. When the rotating block 87 is retracted into the block slot 85, the transmission shaft 82 no longer drives the transmission compartment 88 to rotate when it rotates.

[0029] The transmission clamping block 811 is fixedly mounted on the edge of the transmission turntable 810. The transmission turntable 810 is connected to the plate leveling mechanism 9 through the transmission clamping block 811. When the transmission turntable 810 rotates, it can drive the plate leveling mechanism 9 to move up and down. When the plate leveling mechanism 9 can move up and down, the transmission shaft 82 rotates through the transmission bin 88 to drive the transmission turntable 810 to rotate. When the plate leveling mechanism 9 cannot move up and down, the transmission shaft 82 rotates and the rotating block 87 is retracted into the inside of the block slide groove 85. At this time, the rotation of the transmission shaft 82 no longer drives the transmission bin 88 to rotate.

[0030] When working, the driving motor 1 can drive the second upper roller 72 to rotate. When the second upper roller 72 rotates, it can drive the transmission gear 83 to rotate through the roller transmission gear 75 and the transmission chain 84. When the transmission gear 83 rotates, it can drive the transmission shaft 82 to rotate. When the plate leveling mechanism 9 can move up and down, the end of the transmission shaft 82 is connected with the fixed block 89 inside the transmission warehouse 88 through the fixed block 89. When the rotating block 87 is connected with the fixed block 89, the rotation of the transmission shaft 82 can synchronously drive the transmission warehouse 88 to rotate. When the transmission warehouse 88 rotates, it can drive the transmission turntable 810 to rotate. When the material leveling mechanism 9 cannot move up and down, the transmission turntable 810 cannot rotate. When the transmission shaft 82 rotates, the rotating block 87 and the fixed block 89 are squeezed into the inside of the block slide groove 85. At this time, the rotation of the transmission shaft 82 no longer drives the transmission bin 88 to rotate. The clamping mechanism of the rotating block 87 and the fixed block 89 can enable the plate leveling mechanism 9 to move up and down, and when the plate leveling mechanism 9 cannot move up and down, the transmission shaft 82 can rotate alone, so that the transmission mechanism 8 can drive the plate leveling mechanism 9 to flatten the impurities raised on the surface of the plate when the adjustment is satisfied.

[0031] The difference from the above embodiment is that, please refer to Figure 5 and Figure 7The plate leveling mechanism 9 includes a snap fixing frame 91, which is fixedly mounted on the top of the device body 4. A movable block snap 92 is fixedly mounted inside the snap fixing frame 91, and an upper movable block 93 is clamped inside the movable block snap 92. The top of the upper movable block 93 is fixedly connected to an upper fixed column 94, and the top of the upper fixed column 94 is fixedly connected to a fixed column connecting plate 95. One side of the fixed column connecting plate 95 is fixedly mounted with a connecting plate slide groove 96. The bottom of the upper movable block 93 is fixedly connected to an extrusion and pushing cylinder 97. A lifting slide rod 98 is slidably mounted inside the upper movable block 93, and the bottom of the lifting slide rod 98 is fixedly connected to a plate leveling block 99. A slider limiting ring 910 is fixedly mounted on the outside of the lifting slide rod 98, and a lower movable block 911 is slidably mounted on the outside of the plate leveling block 99. The inner side of the movable block buckle 92 is engaged with the outer side of the upper movable block 93 , and the movable block buckle 92 can limit the position of the upper movable block 93 .

[0032] When the raised plate passes through the plate leveling block 99, it can drive the plate leveling block 99 to move upward. When the plate leveling block 99 moves upward, it can drive the lifting slide bar 98 to move upward. When the lifting slide bar 98 moves upward, it can drive the lower movable block 911 to move upward through the slider limit ring 910. When the lower movable block 911 moves upward, it can push the movable block buckle 92 and fit into the bottom of the upper movable block 93. After the lower movable block 911 and the upper movable block 93 fit together, the inclined structure at the bottom of the lower movable block 911 can make the upper movable block 93 no longer engage with the movable block buckle 92. Then the movable block buckle 92 can move downward and drive the extrusion pushing cylinder 97 to move downward. When the extrusion pushing cylinder 97 moves downward, it can drive the plate leveling block 99 to descend and punch the impurities raised on the plate.

[0033] When the driving plate 93 cannot move downward, the fixed column connecting plate 95 and the connecting plate slot 96 cannot move downward. After the connecting plate slot 96 cannot move downward, the driving plate 93 can be restricted by the driving block 811 so that the driving turntable 810 no longer rotates.

[0034] When the plate passes through the turntable 5, if there are hard impurities on the surface of the plate, the impurity protrusions can touch the plate flat block 99 to move upward, and when the plate flat block 99 moves upward, it can drive the lifting slide bar 98 to move upward. When the lifting slide bar 98 moves upward, it can drive the lower movable block 911 to move upward through the slider limit ring 910. When the lower movable block 911 moves upward, it can push the movable block buckle 92 away and fit the bottom of the upper movable block 93. After the lower movable block 911 fits with the upper movable block 93, the inclined structure at the bottom of the lower movable block 911 can make the upper movable block 93 no longer fit with the movable block buckle 92, and then the movable block buckle 92 can move downward and drive the extrusion pushing cylinder 97 to move downward. When the extrusion pushing cylinder 97 moves downward, it can drive the plate flat block 99 to descend and punch the impurities protruding on the plate, and fix the column connecting plate 95 after the punching is completed. After the upper movable block 93 cannot move downward, the fixed column connecting plate 95 and the connecting plate slide 96 cannot move downward. After the connecting plate slide 96 cannot move downward, the transmission block 811 can be used to limit the transmission turntable 810 so that the transmission turntable 810 no longer rotates. After the upper movable block 93 moves upward, the plate leveling block 99 moves upward under the pressure of the groove on the plate, so that the plate leveling mechanism 9 can return to its position after each plate leveling block 99 punches the plate, so that the plate leveling mechanism 9 can quickly perform the next automatic triggering plate leveling operation after each punching is completed.

[0035] Example 2: A calendering method for processing metal sheets, using the calendering device described in Example 1, comprises the following steps: At the beginning of the process, the plate is firstly passed through the first rolling mechanism 6 for preliminary rolling. When impurities appear in the plate, the first upper roller 64 can rise to prevent the impurities in the plate from damaging the first upper roller 64. When the plate with the protrusion on the top passes under the plate leveling mechanism 9, the plate leveling mechanism 9 can be triggered; After the plate leveling mechanism 9 is triggered, the transmission mechanism 8 can drive the plate leveling mechanism 9 to flatten the impurities raised on the plate; After the stamping is completed, the plate is subjected to a second rolling and flattening process by the second rolling mechanism 7 .

[0036] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
