Description

Technical Field

[0001] This invention relates to the field of steel strip coil feeding technology, specifically to a multi-material coil uncoiling device. Background Technology

[0002] The production of drawer slides requires steel strips with a width of approximately 8-15cm. Before use, these steel strips are mostly in coils, necessitating the use of a steel strip uncoiling device. This uncoiling device is a crucial piece of equipment in the steel industry for processing steel strip coils. It is widely used in steel strip pretreatment, shearing, and straightening processes. As the core component of the uncoiling device, it is responsible for smoothly unwinding the steel strip coil from the drum.

[0003] Currently, multiple steel strip rolls are often mounted side-by-side on the tensioning shaft of an uncoiler to facilitate steel strip feeding. Multiple steel strip rolls can be installed by controlling the opening and closing of the tensioning shaft in a single operation. A stop is fixed on the tensioning shaft to limit the movement of the steel strip rolls, preventing them from shifting or scattering. This eliminates the need to control the opening and closing of the tensioning shaft for each group of steel strip rolls being fed, thus reducing workload.

[0004] However, in current multi-coil uncoiling devices, after loading multiple coils, the limiting structure at the end of each coil needs to be manually adjusted after use to ensure that the limiting structure contacts the inner set of steel strip coils. The adjustment process is cumbersome and time-consuming, thus reducing work efficiency. Therefore, in view of this, a multi-coil uncoiling device is proposed to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention proposes a multi-roll unwinding device to solve the technical problem mentioned in the background art: after loading multiple rolls, existing multi-roll unwinding devices require manual adjustment of the limiting structure at the end of each roll after use, which is a cumbersome and time-consuming process, thus reducing work efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-material roll unwinding device, comprising:

[0007] A frame, on which a rotatable mounting plate is provided;

[0008] Tensioning plates are arranged in multiple sets in a circumferential direction, and each set is slidably mounted on the mounting plate along the radius of the mounting plate. The mounting plate is also provided with a drive mechanism that drives multiple sets of tensioning plates to slide simultaneously. The tensioning plates are provided with mounting frames.

[0009] A first stop is provided on the tensioning plate, and a second stop is slidably provided on the tensioning plate;

[0010] A connecting block is slidably disposed within the mounting frame and can be selectively connected to the second stop. A first elastic element is provided between the connecting block and the inner wall of the mounting frame.

[0011] A reset mechanism is disposed within the mounting frame and can be selectively connected to or separated from the connecting block to drive the connecting block to reset and compress the first elastic element.

[0012] In a preferred embodiment, the mounting plate has multiple sets of sliding grooves along its radius, and the end of the tensioning plate is provided with a slider, which is slidably engaged in the sliding groove.

[0013] In a preferred embodiment, the first stop is slidably disposed on the tensioning plate, and the slider is provided with a rotatable threaded post, which is screwed onto the first stop.

[0014] In a preferred embodiment, a first anti-collision strip is provided at one end of the first guard, and a second anti-collision strip is provided at the opposite end of the second guard.

[0015] In a preferred embodiment, the drive mechanism includes:

[0016] A lead screw, rotatably mounted on the mounting plate along its axis; and

[0017] A threaded sleeve is fitted onto the lead screw and screwed to it. Each tensioning plate is provided with at least two sets of hinged and parallel support rods, which are hinged to the threaded sleeve.

[0018] In a preferred embodiment, the second stop is screwed with a bolt, which is inserted into the connecting block when tightened.

[0019] In a preferred embodiment, the reset mechanism includes:

[0020] The rack is slidably disposed within the mounting frame;

[0021] A transmission assembly, disposed on one set of the support rods and connected to the rack, drives the rack to slide as the support rods rotate about their hinge point with the mounting frame; and

[0022] A connecting component is disposed on the rack to connect it to the connecting block during the sliding of the rack.

[0023] In a preferred embodiment, the transmission assembly includes:

[0024] The drive gear is located at the hinge point between one set of the support rods and the mounting frame;

[0025] A first reversing wheel is rotatably disposed within the mounting frame along its axis and meshes with the driving gear. A first accelerating wheel, coaxially connected to one side of the first reversing wheel, is disposed thereon, and the diameter of the first accelerating wheel is larger than that of the first reversing wheel.

[0026] The second reversing wheel is rotatably disposed within the mounting frame along its axis and meshes with the first accelerating wheel. A second accelerating wheel is coaxially connected to one side of the second reversing wheel. The diameter of the second accelerating wheel is larger than that of the second reversing wheel, and the second accelerating wheel meshes with the rack.

[0027] In a preferred embodiment, a limiting block is provided on the connecting block, and a limiting groove is formed in the mounting frame, wherein the limiting block is slidably engaged in the limiting groove.

[0028] In a preferred embodiment, the connection component includes:

[0029] A wedge-shaped block is provided, wherein a mounting groove is provided on the rack, and the wedge-shaped block is slidably engaged at the opening of the mounting groove and extends outward;

[0030] A fixing post is disposed on the wedge-shaped block and can pass through the connecting block; the bolt passes through the connecting block and can abut against the fixing post.

[0031] A second elastic element is disposed between the wedge block and the mounting groove.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] In use, this device allows multiple sets of steel strip coils to be used to be placed on multiple tensioning plates. A drive mechanism controls the simultaneous sliding of these tensioning plates to tension the steel strip coils, facilitating feeding. After the steel strip coils are installed, a second stop is installed on the tensioning plate and connected to the connecting block. Then, the connection between the reset mechanism and the connecting block is released. Under the action of the first elastic element, the connecting block slides within the mounting frame, causing the second stop to slide towards the first stop, clamping and limiting the installation of the multiple sets of steel strip coils to prevent displacement and scattering. Furthermore, after one set of steel strip coils is used, the first elastic element causes the second stop to slide, automatically clamping the remaining sets. After all the installed steel strip coils have been used, the second stop can be disassembled and multiple sets of tension plates can be controlled to slide and close to install new steel strip coils. The tension plates can then be opened again. During the sliding opening and closing process, the connecting block can be reset by the reset mechanism to facilitate the reinstallation of the second stop. This eliminates the need to manually adjust the position of the second stop after each set of steel strip coils has been used during the entire steel strip coil feeding process, effectively improving the feeding efficiency of steel strip coils.

[0048] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0049] Example:

[0050] like Figure 1 , 2 As shown, the present invention provides a multi-material roll unwinding device, including a frame 101, a rotatable mounting plate 102 on the frame 101, a plurality of tension plates 202 arranged circumferentially on the mounting plate 102, the tension plates 202 being slidably mounted on the mounting plate 102 along the radius of the mounting plate 102, a plurality of sliding grooves 103 being formed on the mounting plate 102 along its radius, and a slider 201 being provided at the end of the tension plate 202, the slider 201 being slidably engaged in the sliding groove 103. The mounting plate 102 is also provided with a driving mechanism for driving the plurality of tension plates 202 to slide simultaneously, the driving mechanism including a lead screw 104 rotatably mounted on the mounting plate 102 along its axis, a threaded sleeve 105 being sleeved on the lead screw 104, and at least two sets of hinged and parallel support rods 204 being provided on each tension plate 202, the support rods 204 being hinged to the threaded sleeves 105.

[0051] In use, the threaded sleeve 105 can be slid on the screw 104 by controlling the screw 104 to rotate. During the sliding process, the threaded sleeve 105 drives the movement of multiple sets of tensioning plates 202 through multiple sets of hinged and parallel support rods 204. Since the multiple sets of tensioning plates 202 are limited by the cooperation of the slider 201 and the slide groove 103, the multiple sets of tensioning plates 202 can open and close. By controlling the multiple sets of tensioning plates 202 to close, and then placing multiple sets of steel strip coils side by side on the multiple sets of tensioning plates 202, and then controlling the multiple sets of tensioning plates 202 to open and tension the steel strip coils, the uncoiling and feeding of steel strip coils can be carried out.

[0052] like Figure 3 , 4As shown in Figure 5, in this embodiment, the tensioning plate 202 is provided with a first stop 205 and a second stop 501 that are slidably mounted. The slider 201 is provided with a rotatable threaded post 207, which is screwed onto the first stop 205. A first anti-collision strip 206 is provided on one end of the first stop 205, and a second anti-collision strip 503 is provided on the opposite end of the second stop 501. The tensioning plate 202 is provided with a mounting frame 203, and a connecting block 406 is slidably mounted inside the mounting frame 203. The connecting block 406 can be selectively connected to the second stop 501, and a first elastic element 408 is provided between the connecting block 406 and the inner wall of the mounting frame 203. A bolt 502 is screwed onto the second stop 501, and the bolt 502, when tightened, passes through the connecting block 406.

[0053] After multiple sets of steel strip rolls are installed, the steel strip rolls abut against the first stop 205. Then, the second stop 501 is slidably locked onto the tension plate 202. Finally, the bolt 502 is rotated to pass through the connecting block 406, connecting the second stop 501 to the connecting block 406. Under the action of the first elastic element 408, the connecting block 406 slides, causing the second stop 501 to slide closer to the first stop 205. This helps the first stop 205 clamp and limit the multiple sets of steel strip rolls. After the outermost set of steel strip rolls is used up, the second stop 501 automatically closes to the first stop 205 without manual adjustment. When all sets of steel strip rolls are used up, the first stop 205 and the second stop 501 close together. The first anti-collision strip 206 and the second anti-collision strip 503 cushion the impact and prevent injury to workers. Furthermore, the first stop 205 can be slid along the axis of the threaded column 207 by rotating the threaded column 207, so as to adjust the initial distance between the first stop 205 and the second stop 501, which facilitates the installation of multiple steel strip coils of different sizes.

[0054] like Figure 3 , 5As shown in Figure 6, in this embodiment, a reset mechanism is provided within the mounting frame 203, which can be selectively connected to or separated from the connecting block 406. The reset mechanism drives the connecting block 406 to reset and compress the first elastic member 408. The reset mechanism includes a rack 401 slidably disposed within the mounting frame 203. A transmission assembly connected to the rack 401 is provided on a set of support rods 204. The transmission assembly drives the rack 401 to slide when the support rods 204 rotate along their hinge point with the mounting frame 203. The transmission assembly includes a drive gear 301, a first reversing wheel 302, and a second reversing wheel 304. The drive gear 301 is located at the hinge point between one set of support rods 204 and the mounting frame 203. The first reversing wheel 302 is rotatably mounted in the mounting frame 203 along its axis and meshes with the drive gear 301. A first acceleration wheel 303 is coaxially connected to one side of the first reversing wheel 302. The second reversing wheel 304 is rotatably mounted in the mounting frame 203 along its axis and meshes with the first acceleration wheel 303. A second acceleration wheel 305 is coaxially connected to one side of the second reversing wheel 304 and meshes with the rack 401.

[0055] During the opening and closing of multiple sets of tension plates 202 controlled by the drive mechanism, the support rod 204 and the mounting frame 203 rotate relative to each other, thereby driving the drive gear 301 to rotate. The drive gear 301, in turn, drives the first reversing wheel 302 and the first acceleration wheel 303 to rotate. The first acceleration wheel 303, in turn, drives the second reversing wheel 304 and the second acceleration wheel 305 to rotate. Since the diameter of the first acceleration wheel 303 is larger than that of the first reversing wheel 302, and the diameter of the second acceleration wheel 305 is larger than that of the second reversing wheel 304, the rack 401 is controlled to slide within a relatively large range during the opening and closing of the tension plates 202. When the multiple sets of tension plates 202 open, the rack 401 moves outward; when the multiple sets of tension plates 202 close, the rack 401 moves inward.

[0056] like Figure 3 , 5 As shown in Figure 7, in this embodiment, a limiting block 407 is provided on the connecting block 406, and a limiting groove 208 is opened in the mounting frame 203. The limiting block 407 is slidably engaged in the limiting groove 208. A connecting component is provided on the rack 401, which connects the rack 401 to the connecting block 406 during the sliding process. The connecting component includes a wedge block 403. An mounting groove 402 is opened on the rack 401. The wedge block 403 is slidably engaged in the opening of the mounting groove 402 and extends outward. A fixing post 404 is provided on the wedge block 403. The fixing post 404 can pass through the connecting block 406. A bolt 502 passes through the connecting block 406 and abuts against the fixing post 404. A second elastic member 405 is provided between the wedge block 403 and the mounting groove 402.

[0057] In the initial state, when the multiple tensioning plates 202 are open and tensioning the steel strip coil, the rack 401 is located on the outermost side of the mounting frame 203, and the fixing post 404 passes through the connecting block 406. One side of the wedge block 403 abuts against the connecting block 406, and the first elastic element 408 is in a compressed state. During the installation of the second stop 501, the bolt 502 is tightened so that it passes through the connecting block 406. During the movement, the bolt 502 pushes the fixing post 404 downward until both the fixing post 404 and the wedge block 403 are retracted into the mounting groove 402 and compress the second elastic element 405. The fixing post 404 and the wedge block 403 are disengaged from the connecting block 406. At this time, the second stop 501 can be controlled to slide and contact the steel strip coil under the restoring ability of the first elastic element 408.

[0058] After the steel strip coil is used up, the connecting block 406 moves to the end of the limiting groove 208, disassembles the second stop 501, and controls the multiple sets of tensioning plates 202 to close. During the closing process, the tensioning plates 202 drive the rack 401 to move to the innermost side of the mounting frame 203. The connecting block 406 is limited by the limiting groove 208 and cannot continue to move. During the movement, the rack 401 can push the wedge block 403 and the fixing post 404 downward through the inclined surface of the wedge block 403 to retract into the mounting groove 4. The second elastic element 405 is compressed until the fixed post 404 is locked into the connecting block 406 again under the action of the second elastic element 405. Then the steel strip coil is fed. After the steel strip coil is fed, the multiple tension plates 202 are opened, and the rack 401 is reset and the connecting block 406 is reset. Then the second stop 501 can be installed to repeat the previous process. Thus, the position of the second stop 501 does not need to be manually adjusted during the entire steel strip coil feeding process.

[0059] Specific usage and beneficial effects of the present invention:

[0060] In use, this device allows multiple sets of steel strip coils to be used to be mounted on multiple sets of tensioning plates 202. A drive mechanism controls the simultaneous sliding of these tensioning plates 202 to tension the steel strip coils, facilitating feeding. After the steel strip coils are installed, the second stop 501 is mounted on the tensioning plate 202 and connected to the connecting block 406. Then, the connection between the reset mechanism and the connecting block 406 is released. Under the action of the first elastic element 408, the connecting block 406 slides within the mounting frame 203, causing the second stop 501 to slide towards the first stop 205, thus clamping and limiting the installation of the multiple sets of steel strip coils and preventing them from shifting or scattering.

[0061] After one set of steel strip coils is used up, the second stop 501 slides under the action of the first elastic element 408 to automatically clamp the other sets of steel strip coils. When all the installed steel strip coils are used up, the second stop 501 can be disassembled and the multiple tension plates 202 can be controlled to slide and close to install new steel strip coils. The tension plates 202 can then be opened again. During the sliding opening and closing process, the tension plates 202 can be reset by the reset mechanism to control the connecting block 406, so that the second stop 501 can be reinstalled. This eliminates the need to manually adjust the position of the second stop 501 after each set of steel strip coils is used up during the entire steel strip coil feeding process, effectively improving the steel strip coil feeding efficiency.

[0062] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to the present invention, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
