Description

Technical Field

[0001] The present invention belongs to the technical field of slitting equipment, and in particular relates to an adjustable slitting equipment and a production process for producing aluminum plates and strips. Background Art

[0002] Aluminum sheet and strip refers to aluminum sheet or strip made of aluminum as the main raw material and mixed with other alloy elements. Aluminum sheet and strip is an important basic material for the development of my country's national economy and is widely used in aviation, aerospace, construction, printing, transportation, electronics, chemical industry, food, medicine and other industries.

[0003] In the field of aluminum sheet and strip production, the performance of slitting equipment plays a vital role in product quality and production efficiency. After the traditional aluminum sheet and strip slitting equipment is used for slitting and cutting, the conveying stability of the slitting is often difficult to ensure. The slitting strips are prone to scattering and offset during the conveying process, which not only affects the subsequent processing steps, but also may lead to a decline in product quality. At the same time, traditional equipment usually requires a separate polishing process after slitting to remove defects and burrs on the surface of the slitting strips, which increases production time and equipment costs. Moreover, traditional equipment lacks an effective mechanism for precise conveying of the slitting strips. The slitting strips may interfere with and collide with each other, affecting the position accuracy of the slitting strips.

[0004] In order to avoid the above-mentioned technical problems, it is necessary to provide an adjustable slitting equipment and production process for the production of aluminum plates and strips to overcome the above-mentioned defects in the prior art. Summary of the invention

[0008] As a preferred embodiment, a first driving motor is fixedly disposed at a rotating portion of one end of the slitting cutting roller, and the first driving motor is fixedly disposed on one side of the first connecting block via a third fixing block.

[0009] As a preferred embodiment, two fixing rods are commonly fixedly provided on adjacent sides of the two first connecting blocks, and a plurality of protective frames are commonly fixedly provided on adjacent sides of the two fixing rods, and each of the protective frames covers the top of the corresponding cutting blade.

[0010] As a preferred embodiment, two fourth connecting blocks are fixedly provided on the back of the workbench, and conveying bottom rollers are rotatably provided on adjacent sides of the two fourth connecting blocks.

[0011] As a preferred implementation scheme, two connecting blocks are fixedly provided on both sides of the workbench, a second cylinder is fixedly provided on the two connecting blocks, and a plurality of supporting legs are fixedly provided on the lower surface of the workbench.

[0012] As a preferred embodiment, a fifth connecting block is fixedly provided on the top of the two second cylinders, a second connecting frame is fixedly provided on the lower surfaces of the two fifth connecting blocks, and two conveying top rollers are rotatably provided on the lower surfaces of the two second connecting frames.

[0013] As a preferred embodiment, a transmission wheel is fixedly provided at the rotation point at one end of the two conveying top rollers, a transmission belt is commonly provided between the two transmission wheels, a second drive motor is fixedly provided on the lower surface of the fifth connecting block on one side through a fourth fixed block, and an output shaft of the second drive motor is fixedly provided on one side of the transmission wheel on one side.

[0014] The present invention discloses a production process of an adjustable slitting device for producing aluminum strips, which is characterized by comprising the following steps:

[0015] S1, first start the first drive motor to drive the slitting cutting roller to rotate, so that the cutting blade is in a ready state, and at the same time, start the first synchronous servo motor and the second synchronous servo motor to control the lower pressure roller and the upper pressure roller to perform low-speed idling preheating in the same thread direction but opposite rotation direction;

[0016] S2, then place the aluminum strip that has been processed in the previous stage on the conveying bottom roller of the workbench, start the second drive motor, drive the conveying top roller to rotate through the transmission wheel and the transmission belt, and cooperate with the conveying bottom roller to smoothly convey the aluminum strip to the strip cutting area;

[0017] S3, when the aluminum strip reaches the strip cutting roller, the first drive motor accelerates and the multiple cutting blades on the strip cutting roller accurately strip the aluminum strip, and the stripped aluminum strip immediately enters between the upper pressure roller and the lower pressure roller;

[0018] S4, then the upper pressure roller and the lower pressure roller, under the control of the first synchronous servo motor and the second synchronous servo motor, clamp and convey the aluminum strip after slitting in opposite rotation directions. Since the spiral patterns on the upper pressure roller and the lower pressure roller are the same and the rotation directions are opposite, the aluminum strip after slitting can be stably conveyed. At the same time, the multiple positioning dividing plates inside the first connecting frame position and separate the aluminum strip after slitting to prevent mutual interference between the strips.

[0019] S5. The aluminum strip after final stripping continues to move forward under the conveyance of the upper and lower pressure rollers and enters the subsequent processing steps or is collected and sorted.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention provides a lower pressure roller and an upper pressure roller. When the aluminum strip after cutting and stripping moves between the upper pressure roller and the lower pressure roller, the two rollers rotate in opposite directions under the synchronous drive of the second synchronous servo motor and the first synchronous servo motor, and the same threads interact with each other. On the one hand, the aluminum strip can be continuously and stably conveyed, ensuring that the aluminum strip after stripping can be smoothly advanced to the next process. On the other hand, the interaction force generated by the reverse rotation can effectively clamp the aluminum strip, which helps to enhance the stability of the aluminum strip during conveying, prevent it from being offset, misplaced or loose, and ensure that the aluminum strip after stripping always remains in a neat and orderly state during conveying.

[0022] The present invention, when the upper pressure roller and the lower pressure roller rotate synchronously in opposite directions and the spiral lines thereon have the same thread direction, will produce a significant grinding and deburring effect on the aluminum strip. When the aluminum strip passes between the upper pressure roller and the lower pressure roller, due to the reverse rotation of the two rollers, a certain pressure and friction force will be applied to the aluminum strip. Such pressure and friction force make the aluminum strip tightly clamped during the conveying process. The spiral lines act as fine files to evenly grind the surface of the aluminum strip. For the aluminum strip after stripping, the burrs that may exist on its edge will be gradually removed under the action of the spiral lines. The same direction design of the spiral lines ensures that in the whole grinding and deburring process, all parts of the aluminum strip can be treated consistently, and there will be no local over- or under-grinding. In this way, it helps to improve the surface quality and production efficiency of the aluminum strip.

[0023] The present invention is provided with a plurality of positioning dividing plates. When the aluminum strip is stripped by the strip cutting roller, these positioning dividing plates can separate different strips to ensure that each strip is transported in a specific channel. When the upper pressure roller and the lower pressure roller rotate synchronously in opposite directions, they not only play the role of grinding and deburring the aluminum strip, but also their spiral patterns can assist in the stable transportation of the strips. Due to the same-direction design of the spiral patterns, the strips are subjected to consistent forces during the transportation process, further avoiding mutual interference and collision between the strips. At the same time, the upper pressure roller and the lower pressure roller clamp and guide the strips, so that the strips can always be kept in the correct position, thereby improving the position accuracy of the strips. Such a design ensures the accuracy and stability of the strips in subsequent processing procedures, and provides a strong guarantee for the production of high-quality aluminum strip products.

[0024] According to the present invention, when the second cylinder is started, it will drive the fifth connecting block connected thereto to perform lifting movement, and the lifting of the fifth connecting block makes the second connecting frame and the two conveying top rollers installed thereon lift synchronously. At the same time, the lifting of the first cylinder can drive the upper pressure roller to perform lifting and adjustment. During the processing of the aluminum strip, for aluminum strips of different thicknesses, the height of the conveying top roller and the upper pressure roller can be accurately adjusted by adjusting the first cylinder and the second cylinder. When processing thicker aluminum strips, it is ensured that the aluminum strips can smoothly enter the slitting equipment and be stably conveyed between the rollers, while ensuring sufficient pressure to achieve good slitting and conveying effects. When processing thinner aluminum strips, the first cylinder and the second cylinder are contracted to reduce the height of the upper pressure roller and the conveying top roller, so as to prevent the aluminum strip from being unstable in conveying or having a poor slitting effect due to the large spacing between the rollers. Through such coordinated adjustment, the processing requirements of aluminum strips of different thicknesses can be met, thereby improving the versatility and adaptability of the equipment.

[0025] The present invention uses two conveying top rollers. On the one hand, the two conveying top rollers greatly increase the contact area with the aluminum plate strip, so that the pressure can be more evenly distributed on the aluminum plate strip. During the conveying process, this uniform pressure distribution ensures that the aluminum plate strip can move forward smoothly without deviation or shaking caused by local uneven force, thereby greatly improving the stability of transportation. On the other hand, when the aluminum plate strip encounters external interference or uneven load during the conveying process, the two conveying top rollers can cooperate with each other to jointly adjust the force state to maintain stable transportation of the aluminum plate strip, which helps to improve the reliability and stability of the equipment.

DETAILED DESCRIPTION

[0033] The present invention will be further described below in conjunction with the embodiments.

[0034] The following examples are used to illustrate the present invention, but they cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions. Simple improvements to the method of the present invention under the premise of the concept of the present invention belong to the scope of protection claimed in the present invention.

[0035] See also Figure 1-6 The present invention provides an adjustable slitting device and production process for aluminum plate and strip production, including a workbench 1, two first connecting blocks 3 are fixedly arranged on the workbench 1, and slitting cutting rollers 4 are rotatably arranged on the adjacent sides of the two first connecting blocks 3, and a plurality of cutting blades 5 are fixedly arranged on the slitting cutting rollers 4, two second connecting blocks 6 are fixedly arranged on the front of the workbench 1, and a lower pressure roller 7 is rotatably arranged on the adjacent sides of the two second connecting blocks 6, a third connecting block 8 is fixedly arranged on each of the two first connecting blocks 3, a first cylinder 9 is fixedly arranged on each of the two third connecting blocks 8, a first connecting frame 10 is fixedly arranged on the bottom ends of the two first cylinders 9, an upper pressure roller 11 is rotatably arranged on the lower surface of the first connecting frame 10, and spiral patterns 12 are provided on the upper pressure roller 11 and the lower pressure roller 7, and the spiral patterns 12 on the upper pressure roller 11 and the lower pressure roller 7 have the same thread direction, and a plurality of positioning dividing plates 32 are arranged inside the first connecting frame 10.

[0036] By setting the lower pressure roller 7 and the upper pressure roller 11, when the aluminum strip after cutting and stripping moves between the upper pressure roller 11 and the lower pressure roller 7, due to the reverse rotation of the two rollers under the synchronous drive of the second synchronous servo motor 15 and the first synchronous servo motor 13, the same threads interact with each other, on the one hand, the aluminum strip can be continuously and stably conveyed, ensuring that the aluminum strip after stripping can be smoothly advanced to the next process; on the other hand, the interaction force generated by this reverse rotation can effectively clamp the aluminum strip, which helps to enhance the stability of the aluminum strip during transportation, prevent it from being offset, misaligned or loose, and ensure that the aluminum strip after stripping always remains neat and orderly during transportation. When the upper pressure roller 11 and the lower pressure roller 7 rotate synchronously in reverse and the spiral lines 12 thereon have the same thread direction, the aluminum strip will have a significant grinding and deburring effect. When the aluminum strip passes between the upper pressure roller 11 and the lower pressure roller 7, the reverse rotation of the two rollers will exert a certain pressure and friction on the aluminum strip. This pressure and friction make the aluminum strip tightly clamped during the conveying process. The spiral pattern 12 is like a fine file, which evenly grinds the surface of the aluminum strip. For the aluminum strip after stripping, the burrs that may exist on its edge will be gradually removed under the action of the spiral pattern 12. The same-direction design of the spiral pattern 12 ensures that all parts of the aluminum strip can be treated consistently during the entire grinding and deburring process, and there will be no local over- or under-grinding. In this way, it helps to improve the surface quality and production efficiency of the aluminum strip.

[0037] like Figure 2 As shown, the present invention provides an embodiment, a first synchronous servo motor 13 is arranged at the rotation part of one end of the lower pressure roller 7, and the first synchronous servo motor 13 is fixedly arranged on one side of the second connecting block 6 through a first fixing block 14, and a second synchronous servo motor 15 is arranged at the rotation part of one end of the upper pressure roller 11, and the second synchronous servo motor 15 is fixedly arranged on one side of the first connecting frame 10 through a second fixing block 16.

[0038] like Figure 2 As shown, the present invention provides an embodiment, a first drive motor 17 is fixedly arranged at the rotation part of one end of the slitting cutting roller 4, and the first drive motor 17 is fixedly arranged on one side of the first connecting block 3 through a third fixing block 18.

[0039] like Figure 4 As shown, the present invention provides an embodiment, two fixing rods 19 are fixedly provided on the adjacent sides of the two first connecting blocks 3, and a plurality of protective frames 20 are fixedly provided on the adjacent sides of the two fixing rods 19, and each protective frame 20 covers the top of the corresponding cutting blade 5.

[0040] like Figure 5 As shown, the present invention provides an embodiment, two fourth connecting blocks 21 are fixedly provided on the back of the workbench 1, and conveying bottom rollers 22 are provided on the adjacent sides of the two fourth connecting blocks 21 to rotate together.

[0041] like Figure 5 As shown, the present invention provides an embodiment, two connecting blocks 23 are fixedly provided on both sides of the workbench 1, a second cylinder 24 is fixedly provided on the two connecting blocks 23, and a plurality of supporting legs 2 are fixedly provided on the lower surface of the workbench 1.

[0042] By setting the first cylinder 9 and the second cylinder 24, when the second cylinder 24 is started, it will drive the fifth connecting block 25 connected thereto to perform lifting and lowering movements. The lifting and lowering of the fifth connecting block 25 causes the second connecting frame 26 and the two conveying top rollers 27 installed thereon to rise and fall synchronously. At the same time, the lifting and lowering of the first cylinder 9 can drive the upper pressure roller 11 to perform lifting and lowering adjustments. During the processing of aluminum strips, for aluminum strips of different thicknesses, the heights of the conveying top roller 27 and the upper pressure roller 11 can be accurately adjusted by adjusting the first cylinder 9 and the second cylinder 24. When processing thicker aluminum strips, it is ensured that the aluminum strips can smoothly enter the stripping equipment and be stably conveyed between the rollers, while ensuring sufficient pressure to achieve good stripping and conveying effects. When processing thinner aluminum strips, the first cylinder 9 and the second cylinder 24 contract to reduce the heights of the upper pressure roller 11 and the conveying top roller 27 to prevent the aluminum strip from being unstable or the stripping effect being poor due to the large spacing between the rollers. Through such coordinated adjustment, the processing requirements of aluminum strips of different thicknesses can be met, thereby improving the versatility and adaptability of the equipment.

[0043] like Figure 5 As shown, the present invention provides an embodiment, the top ends of the two second cylinders 24 are fixedly provided with fifth connecting blocks 25, the lower surfaces of the two fifth connecting blocks 25 are commonly fixedly provided with second connecting frames 26, and the lower surfaces of the two second connecting frames 26 are respectively rotatably provided with two conveying top rollers 27.

[0044] Through the two conveying top rollers 27, on the one hand, the two conveying top rollers 27 greatly increase the contact area with the aluminum strip, so that the pressure can be more evenly distributed on the aluminum strip. During the conveying process, this uniform pressure distribution ensures that the aluminum strip can move forward smoothly without deviation or shaking caused by local uneven force, thereby greatly improving the stability of transportation. On the other hand, when the aluminum strip encounters external interference or uneven load during the conveying process, the two conveying top rollers 27 can cooperate with each other to jointly adjust the force state to maintain stable conveying of the aluminum strip, which helps to improve the reliability and stability of the equipment.

[0045] like Figure 5 and Figure 6 As shown, the present invention provides an embodiment, a transmission wheel 28 is fixedly provided at the rotation point at one end of the two conveying top rollers 27, a transmission belt 29 is commonly provided between the two transmission wheels 28, and a second drive motor 31 is fixedly provided on the lower surface of the fifth connecting block 25 on one side through a fourth fixed block 30, and the output shaft of the second drive motor 31 is fixedly provided on one side of the transmission wheel 28 on one side.

[0046] The present invention discloses a production process of an adjustable slitting device for producing aluminum strips, which is characterized by comprising the following steps:

[0047] S1, first start the first drive motor 17 to drive the slitting cutting roller 4 to rotate, so that the cutting blade 5 is in a ready state, and at the same time, start the first synchronous servo motor 13 and the second synchronous servo motor 15 to control the lower pressure roller 7 and the upper pressure roller 11 to perform low-speed idling preheating in the same thread direction but opposite rotation directions;

[0048] S2, then place the aluminum strip that has been processed in the previous stage on the conveying bottom roller 22 of the workbench 1, start the second drive motor 31, drive the conveying top roller 27 to rotate through the transmission wheel 28 and the transmission belt 29, and cooperate with the conveying bottom roller 22 to smoothly convey the aluminum strip to the strip cutting area;

[0049] S3, when the aluminum strip reaches the strip cutting roller 4, the first drive motor 17 accelerates and the multiple cutting blades 5 on the strip cutting roller 4 accurately strip the aluminum strip, and the stripped aluminum strip immediately enters between the upper pressure roller 11 and the lower pressure roller 7;

[0050] S4, then the upper pressing roller 11 and the lower pressing roller 7, under the control of the first synchronous servo motor 13 and the second synchronous servo motor 15, clamp and convey the aluminum strip after slitting in opposite rotation directions. Since the spiral patterns 12 on the upper pressing roller 11 and the lower pressing roller 7 are the same and rotate in opposite directions, the aluminum strip after slitting can be stably conveyed. At the same time, the multiple positioning dividing plates 32 inside the first connecting frame 10 position and separate the aluminum strip after slitting to prevent mutual interference between the strips.

[0051] S5. The aluminum strip after final stripping continues to move forward under the conveyance of the upper and lower pressure rollers and enters the subsequent processing steps or is collected and sorted.

[0052] The working principle and use process of the present invention are as follows: the multiple cutting blades 5 on the slitting cutting roller 4 accurately cut the aluminum strip into several strips, and the slitting aluminum strip is then moved between the upper pressing roller 11 and the lower pressing roller 7. The spiral patterns 12 on the upper pressing roller 11 and the lower pressing roller 7 are the same and rotate in opposite directions. When the slitting aluminum strip is between the two, due to the reverse rotation of the two rollers, the same threads interact with each other. On the one hand, the aluminum strip can be continuously and stably conveyed, ensuring that the slitting aluminum strip is smoothly advanced to the next process; on the other hand, the interaction force generated by the reverse rotation can effectively clamp the aluminum strip, which helps to enhance the stability of the aluminum strip during the conveying process and prevent it from being offset, misaligned or loosened. The upper and lower pressure rollers 11 and 7 rotate in opposite directions synchronously and the spiral lines 12 thereon have the same thread direction, which will produce a significant grinding and deburring effect on the aluminum strip. When the aluminum strip passes between the upper and lower pressure rollers 11 and 7, the reverse rotation of the two rollers will exert a certain pressure and friction on the aluminum strip. This pressure and friction make the aluminum strip tightly clamped during the transportation process. The spiral lines 12 are like fine files, which evenly grind the surface of the aluminum strip. For the aluminum strip after slitting, the burrs that may exist on its edge will be gradually removed under the action of the spiral lines 12. The same-direction design ensures that during the entire grinding and deburring process, all parts of the aluminum strip can be treated consistently without local over- or under-grinding. In this way, it helps to improve the surface quality and production efficiency of the aluminum strip. By providing a plurality of positioning dividing plates 32, when the aluminum strip is stripped by the strip cutting roller 4, these positioning dividing plates 32 can separate different strips to ensure that each strip is conveyed in a specific channel. When the upper pressure roller 11 and the lower pressure roller 7 rotate synchronously in opposite directions, they not only grind and deburr the aluminum strip, but the spiral texture 12 can also assist in the stable conveying of the strips. Due to the same-direction design of the spiral texture 12, the strips will be subjected to consistent force during the conveying process, thereby ensuring stable conveying of the strips. The mutual interference and collision between the strips are avoided in one step. At the same time, the clamping and guiding effect of the upper pressure roller 11 and the lower pressure roller 7 on the strips enables the strips to always remain in the correct position, thereby improving the position accuracy of the strips. Such a design ensures the accuracy and stability of the strips in subsequent processing steps, and provides a strong guarantee for the production of high-quality aluminum strip products. When the second cylinder 24 is started, it will drive the fifth connecting block 25 connected thereto to perform lifting and lowering movements. The lifting and lowering of the fifth connecting block 25 causes the second connecting frame 26 and the two conveying top rollers 27 installed thereon to rise and fall synchronously. At the same time, the lifting and lowering of the first cylinder 9 can drive the upper pressure roller 11 to perform lifting and lowering adjustments. During the processing of the aluminum strip, for aluminum strips of different thicknesses,By adjusting the first cylinder 9 and the second cylinder 24, the height of the conveying top roller 27 and the upper pressure roller 11 can be accurately adjusted. When processing thicker aluminum strips, it is ensured that the aluminum strips can smoothly enter the slitting equipment and be stably conveyed between the rollers, while ensuring sufficient pressure to achieve good slitting and conveying effects. When processing thinner aluminum strips, the first cylinder 9 and the second cylinder 24 are contracted to reduce the height of the upper pressure roller 11 and the conveying top roller 27 to prevent the aluminum strip from being unstable in conveying or having a poor slitting effect due to the large spacing between the rollers. Through such coordinated adjustment, the processing requirements of aluminum strips of different thicknesses can be met, and the versatility of the equipment is improved. The two conveying top rollers 27 greatly increase the contact area with the aluminum strip, so that the pressure can be more evenly distributed on the aluminum strip. During the conveying process, this uniform pressure distribution ensures that the aluminum strip can move forward smoothly without deviation or shaking caused by local uneven force, thereby greatly improving the stability of the conveying. On the other hand, when the aluminum strip encounters external interference or uneven load during the conveying process, the two conveying top rollers 27 can cooperate with each other to adjust the force state together to maintain the stable conveying of the aluminum strip, which helps to improve the reliability and stability of the equipment.

A production process of an adjustable slitting device for producing aluminum strips based on claims 1-8, characterized in that; The following steps are involved: S1, first start the first drive motor (17) to drive the slitting cutting roller (4) to rotate, so that the cutting blade (5) is in a ready state, and at the same time, start the first synchronous servo motor (13) and the second synchronous servo motor (15) to control the lower pressure roller (7) and the upper pressure roller (11) to perform low-speed idling preheating in the same thread direction but opposite rotation directions; S2, then placing the aluminum strip that has undergone the preliminary treatment on the conveying bottom roller (22) of the workbench (1), starting the second drive motor (31), driving the conveying top roller (27) to rotate through the transmission wheel (28) and the transmission belt (29), and cooperating with the conveying bottom roller (22) to smoothly convey the aluminum strip to the strip cutting area; S3, when the aluminum strip reaches the strip cutting roller (4), the first drive motor (17) accelerates its rotation, and the multiple cutting blades (5) on the strip cutting roller (4) accurately strip the aluminum strip, and the stripped aluminum strip then enters between the upper pressure roller (11) and the lower pressure roller (7); S4, then the upper pressure roller (11) and the lower pressure roller (7) are controlled by the first synchronous servo motor (13) and the second synchronous servo motor (15) to clamp and convey the aluminum strip after slitting in opposite directions of rotation. Since the spiral patterns (12) on the upper pressure roller (11) and the lower pressure roller (7) are the same and rotate in opposite directions, the aluminum strip after slitting can be stably conveyed. At the same time, the multiple positioning dividing plates (32) inside the first connecting frame (10) position and separate the aluminum strip after slitting to prevent mutual interference between the strips. S5. The aluminum strip after final stripping continues to move forward under the conveyance of the upper and lower pressure rollers and enters the subsequent processing steps or is collected and sorted.
