Description

Technical Field

[0001] This invention relates to the field of cold-rolled steel strip processing technology, specifically to an uncoiling and cutting device for cold-rolled steel strip processing. Background Technology

[0002] Cold-rolled steel strip is made from hot-rolled coils by rolling at room temperature below the recrystallization temperature. Longer strips delivered in coils are called steel strips, also known as coils. Cold-rolled steel has excellent properties; through cold rolling, thinner and more precise cold-rolled steel strips can be obtained. It features high flatness, high surface finish, and ease of coating. It also has high stamping performance, is non-aging, and has a low yield point. Therefore, cold-rolled steel sheets have a wide range of applications, mainly in the automotive, printed steel drum, construction, building materials, and bicycle industries. It is also the best material for producing organically coated steel sheets.

[0003] Since cold-rolled steel strip is sold in coils, it must be uncoiled before use. After uncoiling, it needs to be straightened and cut. In the existing technology, uncoiling of cold-rolled steel strip requires an uncoiler, and cutting is carried out on a cutting production line, which takes up a lot of space and is also costly.

[0004] Patent application number "201810306825.4" discloses an integrated uncoiling and cutting machine for cold-rolled steel strip. The key technical features are: a frame with two U-shaped blocks symmetrically fixed at one end of the frame about its horizontal axis; a cold-rolled steel strip coil detachably connected between the two U-shaped blocks; a fixed shaft of the cold-rolled steel strip coil rotatably connected within a first bearing seat; the first bearing seat slidably connected within the opening of the U-shaped blocks; a stop block slidably connected vertically within the U-shaped blocks; a first groove for the stop block to slide on the U-shaped blocks; a first spring connecting the stop block and the bottom of the first groove; an upper drive roller and a lower drive roller rotatably connected to the frame; a first gear and a second gear fixed to the ends of the upper and lower drive rollers, respectively; a servo motor fixed to the frame; and the servo motor driving the lower drive roller to rotate. The device occupies a relatively small space.

[0005] The aforementioned device places the cold-rolled steel strip coil directly inside the U-shaped block. When the cold-rolled steel strip coil rotates, it will rub against the U-shaped block, which not only damages the rotating shaft of the cold-rolled steel strip coil, but also generates a lot of friction noise, affecting the working environment of the workers. Moreover, the aforementioned device directly conveys the cold-rolled steel strip coil through the upper and lower drive rollers, but the gap between the upper and lower drive rollers cannot be adjusted, which means that the device cannot convey cold-rolled steel strip coils of different thicknesses, resulting in limited applicability.

[0006] To address the aforementioned problems, the inventors have proposed an uncoiling and cutting device for cold-rolled steel strip processing. Summary of the Invention

[0007] To address the issue of significant frictional noise during the rotation of cold-rolled steel strip coils and the inability to adjust the gap between the upper and lower drive rollers, the present invention aims to provide an uncoiling and cutting device for processing cold-rolled steel strips.

[0008] To solve the above technical problems, the present invention adopts the following technical solution: It includes a base plate, with a steel strip support plate fixedly connected to one side of the top of the base plate. Two steel strip support plates are provided. A cold-rolled steel strip coil is arranged above the steel strip support plate. A clamping mechanism is provided on the top of the steel strip support plate. First mounting plates are fixedly connected to the front and rear of the top of the base plate. A first tensioning roller is rotatably connected between the two first mounting plates. Second mounting plates are fixedly connected to the front and rear of the top of the base plate. A tensioning groove is formed on the front of the second mounting plate. A tensioning slider is slidably connected to the inner surface of the tensioning groove. A second tensioning roller is rotatably connected between the two tensioning sliders. Tensioning telescopic rods are fixedly connected to the front and back of the base plate. One end of each tensioning telescopic rod is fixedly connected to the outer surface of the tensioning slider. The front of the top of the base plate... Both the upper and lower parts are fixedly connected to a third mounting plate. A lower drive roller is rotatably connected between the two third mounting plates. An adjusting groove is provided on the front of the third mounting plate and above the lower drive roller. An adjusting slider is slidably connected to the inner surface of the adjusting groove. An upper drive roller is rotatably connected between the two adjusting sliders. A conveying mechanism is provided at the front of the third mounting plate, and a cutting mechanism is provided on the other side of the top of the base plate. By setting a tensioning telescopic rod, activating the tensioning telescopic rod drives the tensioning slider to descend, thereby adjusting the tension of the cold-rolled steel strip coil during conveying and increasing the uncoiling effect of the device. The cold-rolled steel strip coil is conveyed by the lower drive roller and the upper drive roller to ensure the normal operation of the device. At the same time, the gap between the lower drive roller and the upper drive roller can be adjusted by the conveying mechanism, so that the device can convey cold-rolled steel strip coils of different thicknesses, increasing the applicability of the device.

[0009] Preferably, the conveying mechanism includes a conveying motor, a conveying mounting plate is fixedly connected to the front of the third mounting plate, the outer surface of the conveying motor is fixedly connected to the top of the conveying mounting plate, a conveying spline shaft is fixedly connected to one end of the lower drive roller shaft, a conveying spline cylinder is sleeved and slidably connected to the outer surface of the conveying spline shaft, the conveying motor provides power for the rotation of the lower drive roller and the upper drive roller, the conveying mounting plate is used to install the conveying motor, the conveying spline shaft allows the conveying spline cylinder to rotate with the conveying spline shaft, and at the same time allows the conveying spline cylinder to move along the conveying spline shaft, ensuring normal operation of the device while adjusting the position of the conveying output gear, the outer surface of the conveying spline cylinder... A conveying output gear is fitted and fixedly connected to the surface of the conveying mounting plate. A conveying adjustment groove is formed on the top of the conveying mounting plate, and a conveying adjustment slider is slidably connected to the inner surface of the conveying adjustment groove. The top of the conveying adjustment slider is rotatably connected to the outer surface of the conveying spline cylinder via a rotating frame. A conveying adjustment threaded rod is rotatably connected to the bottom of the conveying mounting plate, and a conveying adjustment threaded sleeve is threadedly connected to the outer surface of the conveying adjustment threaded rod. The outer surface of the conveying adjustment threaded sleeve is fixedly connected to the bottom of the conveying adjustment slider. The conveying output gear can mesh with the first, second, and third conveying input gears respectively, ensuring that the lower drive roller and the upper drive roller maintain driving... Simultaneously, the distance between the lower drive roller and the upper drive roller can be changed. The conveyor adjusting threaded rod is used to drive the conveyor adjusting threaded sleeve to move, the conveyor adjusting threaded sleeve is used to drive the conveyor adjusting slider to move, and the conveyor adjusting slider is used to drive the conveyor splined cylinder to move, ensuring the normal operation of the device. One end of the upper drive roller shaft is fixedly connected to a conveyor extension shaft, and the outer surface of the third mounting plate is fixedly connected to a conveyor adjusting telescopic rod. One end of the conveyor adjusting telescopic rod is rotatably connected to the outer surface of the conveyor extension shaft through a bearing. The conveyor extension shaft is used to install the first conveyor input gear, the second conveyor input gear, and the third conveyor input gear. The conveyor adjusting telescopic rod is used to adjust the conveyor extension... The height of the extended shaft allows the first, second, and third input gears to mesh with the output gears, respectively. The first, second, and third input gears are fitted and fixedly connected to the outer surface of the extended shaft. The meshing of these gears with the output gears allows for changing the distance between the lower and upper drive rollers, enabling the device to convey cold-rolled steel strip coils of varying thicknesses and increasing its versatility.

[0010] Preferably, the cutting mechanism includes a cutting box, the top of the base plate is fixedly connected to the bottom of the cutting box via a storage box, two upper cutting support rollers are rotatably connected to the inner surface of the cutting box, and two lower cutting support rollers are rotatably connected to the inner surface of the cutting box below the upper cutting support rollers. The cutting box is used to install the upper and lower cutting support rollers, which support the cold-rolled steel strip coil during cutting, facilitating the cutting process. A cutting telescopic rod is fixedly connected to the bottom of the inner surface of the cutting box. There are two cutting telescopic rods. A cutting blade is fixedly connected to one end of the cutting telescopic rod. A cutting inlet groove is opened on one side of the cutting box, and a cutting outlet groove is opened on the other side of the cutting box. Through the setting of the cutting mechanism, due to the clamping and support of the upper and lower cutting support rollers, the cutting telescopic rod is activated to drive the cutting blade to rise, thereby cutting the cold-rolled steel strip coil. The uncoiling and cutting of the cold-rolled steel strip coil can be completed on one machine, which occupies less space and has a lower production cost.

[0011] Preferably, the clamping mechanism includes a clamping placement block, the bottom of which is fixedly connected to the top of the steel strip support plate. A clamping placement groove is formed on the top of the clamping placement block. Clamping first rotating rollers are rotatably connected to both sides of the inner surface of the clamping placement groove. Clamping rotating shafts are rotatably connected to both sides of the top of the clamping placement block. The clamping first rotating rollers ensure smooth rotation of the cold-rolled steel strip coil shaft, preventing friction between the coil shaft and the clamping placement groove, reducing damage to the coil shaft, and minimizing noise during uncoiling, thus improving the working environment for workers. A clamping rotating frame is fixedly connected to the outer surface of the clamping rotating shaft, and a clamping second rotating roller is rotatably connected to the inner surface of the clamping rotating frame. A clamping rotating disk is fixedly connected to one end of the clamping rotating shaft. A clamping spring plate is fixedly connected to the outer surface of the steel strip support plate. A clamping rotating frame is used to install and clamp the second rotating roller. The clamping second rotating roller limits the rotation axis of the cold-rolled steel strip coil to prevent the cold-rolled steel strip coil from detaching and to increase the stability of the cold-rolled steel strip coil during rotation. A clamping spring rod is slidably connected through the bottom of the clamping spring plate. A clamping spring is sleeved on the outer surface of the clamping spring rod. The outer surface of the clamping rotating disk has clamping spring holes that are adapted to the clamping spring rod. The number of clamping spring holes is set to several. Pulling the clamping spring rod away from the clamping spring holes releases the limitation on the clamping rotating disk. Rotating the clamping rotating disk causes the clamping rotating shaft to rotate, which drives the second rotating roller to rotate, thereby moving the second rotating roller away from the clamping placement groove, thus facilitating the installation and replacement of the cold-rolled steel strip coil.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. By setting up the tensioning telescopic rod, activating the tensioning telescopic rod drives the tensioning slider to descend, thereby adjusting the tension during the conveying of cold-rolled steel strip coils and increasing the uncoiling effect of the device. The cold-rolled steel strip coils are conveyed by the lower drive roller and the upper drive roller to ensure the normal operation of the device. At the same time, the gap between the lower drive roller and the upper drive roller can be adjusted by the conveying mechanism, so that the device can convey cold-rolled steel strip coils of different thicknesses, increasing the applicability of the device.

[0014] 2. By setting the first rotating roller to clamp, the shaft of the cold-rolled steel strip coil rotates smoothly, preventing the shaft of the cold-rolled steel strip coil from rubbing against the clamping groove, reducing damage to the shaft of the cold-rolled steel strip coil, and reducing noise when the cold-rolled steel strip coil is uncoiled, thus improving the working environment for workers. By setting the second rotating roller to clamp and fix the shaft of the cold-rolled steel strip coil, the stability of the cold-rolled steel strip coil during rotation is increased.

[0015] 3. Through the setting of the cutting mechanism, the upper and lower support rollers clamp and support the cutting, and the cutting telescopic rod is activated to drive the cutting blade to rise, thereby cutting the cold-rolled steel strip coil. The uncoiling and cutting of the cold-rolled steel strip coil can be completed on one machine, which occupies less space and reduces production costs. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figure 1-11As shown, this invention provides an uncoiling and cutting device for cold-rolled steel strip processing, including a base plate 1. A steel strip support plate 2 is fixedly connected to one side of the top of the base plate 1. There are two steel strip support plates 2. A cold-rolled steel strip coil 3 is arranged above the steel strip support plate 2. A clamping mechanism 120 is arranged on the top of the steel strip support plate 2.

Second mounting plates 6 are fixedly connected to the front and rear of the top of the base plate 1. A tensioning groove 7 is opened on the front of the second mounting plate 6. A tensioning slider 8 is slidably connected to the inner surface of the tensioning groove 7. A second tensioning roller 9 is rotatably connected between the two tensioning sliders 8.

One end of the tensioning telescopic rod 10 is fixedly connected to the outer surface of the tensioning slider 8. A third mounting plate 1 is fixedly connected to the front and rear of the top of the base plate 1. 1. A lower drive roller 12 is rotatably connected between two third mounting plates 11. An adjusting groove 13 is provided on the front of the third mounting plate 11 and above the lower drive roller 12. An adjusting slider 14 is slidably connected to the inner surface of the adjusting groove 13. An upper drive roller 15 is rotatably connected between two adjusting sliders 14. A conveying mechanism 130 is provided at the front of the third mounting plate 11, and a cutting mechanism 140 is provided on the other side of the top of the base plate 1. By setting the tensioning telescopic rod 10, the tensioning telescopic rod 10 is activated to drive the tensioning slider 8 to descend, thereby adjusting the tension of the cold-rolled steel strip coil 3 during conveying and increasing the uncoiling effect of the device. The cold-rolled steel strip coil 3 is conveyed by the lower drive roller 12 and the upper drive roller 15 to ensure the normal operation of the device. At the same time, the gap between the lower drive roller 12 and the upper drive roller 15 can be adjusted by the conveying mechanism 130, so that the device can convey cold-rolled steel strip coils 3 of different thicknesses, increasing the applicability of the device.

[0031] The conveying mechanism 130 includes a conveying motor 131, a conveying mounting plate 132 fixedly connected to the front of the third mounting plate 11, the outer surface of the conveying motor 131 fixedly connected to the top of the conveying mounting plate 132, a conveying spline shaft 133 fixedly connected to one end of the shaft of the lower drive roller 12, and a conveying spline cylinder 134 sleeved and slidably connected to the outer surface of the conveying spline shaft 133.

[0032] By adopting the above technical solution, the conveyor motor 131 provides power for the rotation of the lower drive roller 12 and the upper drive roller 15. The conveyor mounting plate 132 is used to install the conveyor motor 131. The conveyor spline shaft 133 enables the conveyor spline cylinder 134 to rotate with the conveyor spline shaft 133, and at the same time enables the conveyor spline cylinder 134 to move along the conveyor spline shaft 133, ensuring the normal operation of the device while adjusting the position of the conveyor output gear 135.

[0033] A conveying output gear 135 is fitted and fixedly connected to the outer surface of the conveying spline cylinder 134. A conveying adjustment groove 136 is provided on the top of the conveying mounting plate 132. A conveying adjustment slider 137 is slidably connected to the inner surface of the conveying adjustment groove 136. The top of the conveying adjustment slider 137 is rotatably connected to the outer surface of the conveying spline cylinder 134 through a rotating frame. A conveying adjustment threaded rod 138 is rotatably connected to the bottom of the conveying mounting plate 132. A conveying adjustment threaded sleeve 139 is threadedly connected to the outer surface of the conveying adjustment threaded rod 138. The outer surface of the conveying adjustment threaded sleeve 139 is fixedly connected to the bottom of the conveying adjustment slider 137.

[0034] By adopting the above technical solution, the conveying output gear 135 can mesh with the conveying input first gear 1312, the conveying input second gear 1313, and the conveying input third gear 1314 respectively, so that the lower drive roller 12 and the upper drive roller 15 can change the distance between the lower drive roller 12 and the upper drive roller 15 while ensuring driving. The conveying adjustment threaded rod 138 is used to drive the conveying adjustment threaded sleeve 139 to move, the conveying adjustment threaded sleeve 139 is used to drive the conveying adjustment slider 137 to move, and the conveying adjustment slider 137 is used to drive the conveying spline cylinder 134 to move, ensuring the normal operation of the device.

[0035] One end of the upper drive roller 15 shaft is fixedly connected to a conveying extension shaft 1310, and the outer surface of the third mounting plate 11 is fixedly connected to a conveying adjustment telescopic rod 1311. One end of the conveying adjustment telescopic rod 1311 is rotatably connected to the outer surface of the conveying extension shaft 1310 through a bearing.

[0036] By adopting the above technical solution, the conveying extension shaft 1310 is used to install the first conveying input gear 1312, the second conveying input gear 1313, and the third conveying input gear 1314, and the conveying adjustment telescopic rod 1311 is used to adjust the height of the conveying extension shaft 1310 so that the first conveying input gear 1312, the second conveying input gear 1313, and the third conveying input gear 1314 can respectively mesh with the conveying output gear 135.

[0037] A first conveying input gear 1312 is sleeved and fixedly connected to the outer surface of the conveying extension shaft 1310, a second conveying input gear 1313 is sleeved and fixedly connected to the outer surface of the conveying extension shaft 1310, and a third conveying input gear 1314 is sleeved and fixedly connected to the outer surface of the conveying extension shaft 1310.

[0038] By adopting the above technical solution, the first input gear 1312, the second input gear 1313, and the third input gear 1314 are respectively engaged with the output gear 135, which can change the distance between the lower drive roller 12 and the upper drive roller 15, thereby enabling the device to transport cold-rolled steel strip coils 3 of different thicknesses and increasing the applicability of the device.

[0039] The cutting mechanism 140 includes a cutting box 141. The top of the base plate 1 is fixedly connected to the bottom of the cutting box 141 through a storage box. An upper cutting support roller 142 is rotatably connected to the inner surface of the cutting box 141. There are two upper cutting support rollers 142. A lower cutting support roller 143 is rotatably connected to the inner surface of the cutting box 141 and below the upper cutting support rollers 142. There are two lower cutting support rollers 143.

[0040] By adopting the above technical solution, the cutting box 141 is used to install the upper cutting support roller 142 and the lower cutting support roller 143. The upper cutting support roller 142 and the lower cutting support roller 143 are used to support the steel strip of the cold-rolled steel strip coil 3 during cutting, so as to facilitate the cutting of the device.

[0041] A cutting telescopic rod 144 is fixedly connected to the bottom of the inner surface of the cutting box 141. There are two cutting telescopic rods 144. A cutting blade 145 is fixedly connected to one end of the cutting telescopic rod 144. A cutting inlet groove 146 is opened on one side of the cutting box 141, and a cutting outlet groove 147 is opened on the other side of the cutting box 141.

[0042] By adopting the above technical solution, and through the setting of the cutting mechanism 140, the cutting upper support roller 142 and the cutting lower support roller 143 clamp and support the cutting telescopic rod 144 to drive the cutting blade 145 to rise, thereby cutting the cold-rolled steel strip coil 3. This allows the uncoiling and cutting of the cold-rolled steel strip coil 3 to be completed on one machine, occupying less space and reducing production costs.

[0043] The clamping mechanism 120 includes a clamping and placing block 121. The bottom of the clamping and placing block 121 is fixedly connected to the top of the steel strip support plate 2. A clamping and placing groove 122 is provided on the top of the clamping and placing block 121. A clamping first rotating roller 123 is rotatably connected to both sides of the inner surface of the clamping and placing groove 122. A clamping rotating shaft 124 is rotatably connected to both sides of the top of the clamping and placing block 121.

[0044] By adopting the above technical solution, the setting of the clamping first rotating roller 123 enables the rotating shaft of the cold-rolled steel strip coil 3 to rotate smoothly, preventing the rotating shaft of the cold-rolled steel strip coil 3 from rubbing against the clamping and placing groove 122, reducing damage to the rotating shaft of the cold-rolled steel strip coil 3, and reducing noise when the cold-rolled steel strip coil 3 is uncoiled, thus improving the working environment for workers.

[0045] A clamping rotating frame 125 is fixedly connected to the outer surface of the clamping rotating shaft 124, a clamping second rotating roller 126 is rotatably connected to the inner surface of the clamping rotating frame 125, a clamping rotating disk 127 is fixedly connected to one end of the clamping rotating shaft 124, and a clamping spring plate 128 is fixedly connected to the outer surface of the steel strip support plate 2.

[0046] By adopting the above technical solution, the clamping rotating frame 125 is used to install and clamp the second rotating roller 126. The clamping second rotating roller 126 limits the rotation shaft of the cold-rolled steel strip coil 3, prevents the cold-rolled steel strip coil 3 from detaching, and increases the stability of the cold-rolled steel strip coil 3 when rotating.

[0047] A clamping spring rod 129 is slidably connected through the bottom of the clamping spring plate 128. A clamping spring 1210 is sleeved on the outer surface of the clamping spring rod 129. A clamping spring hole 1211 that matches the clamping spring rod 129 is provided on the outer surface of the clamping rotating disk 127. The number of clamping spring holes 1211 is set to a certain extent.

[0048] By adopting the above technical solution, the clamping spring rod 129 is pulled away from the clamping spring hole 1211, thereby releasing the limit on the clamping rotating disk 127. The clamping rotating disk 127 is rotated to make the clamping rotating shaft 124 rotate. The clamping rotating shaft 124 drives the clamping second rotating roller 126 to rotate, thereby making the clamping second rotating roller 126 away from the clamping placement groove 122, thus facilitating the installation and replacement of the cold-rolled steel strip coil 3.

[0049] Working principle: The shaft of the cold-rolled steel strip coil 3 is placed in the clamping slot 122. The clamping spring rod 129 is pulled to extend the clamping spring 1210, and the clamping spring rod 129 moves away from the clamping spring hole 1211, thereby releasing the limit on the clamping rotating disk 127. The clamping rotating disk 127 is rotated to make the clamping rotating shaft 124 rotate. The clamping rotating shaft 124 drives the clamping rotating frame 125 to make the clamping second rotating roller 126 rotate. The clamping second rotating roller 126 is in close contact with the outer surface of the shaft of the cold-rolled steel strip coil 3. The clamping spring rod 129 is loosened, and the clamping spring 1210 shortens, causing the clamping spring rod 129 to be inserted into the clamping spring hole 1211, limiting and fixing the clamping rotating disk 127. The clamping second rotating roller 126 limits and fixes the shaft of the cold-rolled steel strip coil 3, ensuring the stability of the cold-rolled steel strip coil 3 when rotating.

[0050] The tensioning telescopic rod 10 is activated, which drives the tensioning slider 8 to move along the tensioning groove 7. The tensioning slider 8 drives the second tensioning roller 9 to descend. The second tensioning roller 9 squeezes the coil of cold-rolled steel strip 3, thus tensioning the coil of cold-rolled steel strip 3. The conveying motor 131 is activated, which drives the conveying spline shaft 133 to rotate the lower drive roller 12. At the same time, the conveying spline shaft 133 drives the conveying spline cylinder 134 to rotate the conveying output gear 135. The conveying output gear 135 drives the conveying input third gear 1314 to rotate the conveying extension shaft 1310. The conveying extension shaft 1310 drives the upper drive roller 15 to rotate. The rotation of the lower drive roller 12 and the upper drive roller 15 conveys the cold-rolled steel strip 3. When it is necessary to cut the cold-rolled steel strip 3, the cutting telescopic rod 144 is activated, which drives the cutting blade 145 to rise. Due to the clamping support of the cutting upper support roller 142 and the cutting entry groove 146, the cutting blade 145 cuts the cold-rolled steel strip 3.

[0051] When it is necessary to adjust the distance between the lower drive roller 12 and the upper drive roller 15, rotate the conveyor adjusting threaded rod 138 to move the conveyor adjusting threaded sleeve 139. The conveyor adjusting threaded sleeve 139 drives the conveyor adjusting slider 137 to move along the conveyor adjusting groove 136. The conveyor adjusting slider 137 drives the conveyor spline cylinder 134 to move along the conveyor spline shaft 133. The conveyor spline cylinder 134 drives the conveyor output gear 135 to move. After the conveyor output gear 135 moves to directly below the conveyor input second gear 1313, activate the conveyor adjusting telescopic rod 1311 to drive the conveyor extension shaft 1310 to move the adjusting slider 14 along the adjusting groove 13. The adjusting slider 14 drives the conveyor extension shaft 1310 to lower the conveyor input second gear 1313 and engage with the conveyor output gear 135. At the same time, the adjusting slider 14 drives the upper drive roller 15 to lower, thereby reducing the gap between the upper drive roller 15 and the lower drive roller 12.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
