Description

Technical Field

[0001] The present invention relates to a method for supporting rollers and a supporting mechanism for a horizontal loop structure in a continuous strip production line, which is a metal strip transmission system with a horizontal loop structure and is applicable to equipment in continuous strip annealing production lines, continuous strip galvanizing / coating production lines, and continuous strip degreasing production lines. It belongs to the technical field of metal heat treatment equipment. Technical Background

[0002] Currently, in continuous strip annealing production lines, continuous strip galvanizing / coating production lines, and continuous strip degreasing production lines, in order to ensure that the process section operates continuously during the loading and unloading processes of the unit, a loop device needs to be provided before and after the process section to store metal strips. Among them, there is a horizontal loop structure. To prevent the metal strip from sagging during large strokes of the horizontal loop, a transfer cart needs to be provided in the middle of the horizontal loop structure, and the rollers in the transfer cart are used to support the metal strip running in the loop to ensure that the metal strips between layers do not contact each other after the transfer cart is pulled apart by a large distance, thereby avoiding damage to the surface of the metal strip.

[0003] In the prior art, the roller support structure of the transfer cart of the horizontal loop is a passive rotating roller support structure, and this passive rotating roller support structure has the following problems: (1) The elevation of the roller is at a fixed position, and the contact between the roller and the metal strip is a flat line contact. After the metal strip is tightened, there is only a horizontal tension, which easily causes the friction force between the metal strip and the roller to be less than the bearing damping force, resulting in the roller not rotating due to too small a friction force, and thus the surface of the metal strip is scratched by the roller. (2) Mechanical processing errors cause the elevations of multiple transfer cart rollers to be inconsistent, and the roller and the metal strip are in intermittent contact during the movement of the loop, resulting in the surface of the metal strip being scratched by the roller. Summary of the Invention

[0004] One of the purposes of the present invention is to solve the problems existing in the roller support structure of the transfer cart of the horizontal loop in the prior art, which easily causes the roller not to reduce the friction force, resulting in the roller not rotating due to the lack of friction force and scratching the surface of the metal strip, and the problem of mechanical processing errors causing the surface of the metal strip to be scratched by the roller. A method for supporting rollers of a horizontal loop structure in a continuous strip production line is provided, forming a dynamic roller support structure, which has outstanding substantial features and remarkable technical progress such as a simple support structure, automatic adjustment of the support point, the roller keeps rotating continuously, the friction force between the roller and the metal strip remains constant, and preventing the surface of the metal strip from being scratched by the roller.

[0005] The second object of the present invention is to solve the problems existing in the support structure of the transfer cart rollers of the horizontal loop in the prior art, which are prone to causing no reduction in the friction force of the rollers, resulting in the rollers not rotating due to the lack of friction force and scratching the surface of the metal strip, and the problem that the surface of the metal strip is scratched by the rollers due to machining errors. A roller support mechanism for the horizontal loop structure of a continuous strip production line is provided, forming a dynamic roller support structure, which has prominent substantial features and significant technical progress such as a simple support structure, automatic adjustment of the support point, the rollers keep rotating continuously, the friction force between the rollers and the metal strip remains constant, and preventing the surface of the metal strip from being scratched by the rollers.

[0006] One object of the present invention can be achieved by adopting the following technical solutions:

[0007] A method for supporting rollers in the horizontal loop structure of a continuous strip production line, characterized in that:

[0008] 1) In the horizontal loops at the inlet end and the outlet end of the continuous strip production line, there are respectively provided roller automatic lifting mechanisms, and each roller automatic lifting mechanism is composed of a number of automatic lifting units. The number of automatic lifting units is the same as the number of roller cars in the horizontal loop and forms a one-to-one correspondence relationship;

[0009] 2) The automatic lifting unit drives the roller to move up and down so that the roller remains in contact with the workpiece, forming a dynamic support structure for the roller, so that the workpiece drives the roller to keep rotating from beginning to end;

[0010] 3) The automatic lifting unit automatically drives the roller to move up and down according to the position change of the roller car. Specifically, when the distance between adjacent roller cars becomes smaller and the roller on the roller car is about to leave the workpiece, the automatic lifting unit automatically lifts the roller so that the roller remains in close contact with the workpiece, and the workpiece drives the roller to rotate; when the distance between adjacent roller cars becomes larger and the roller on the roller car is about to lift the workpiece, the automatic lifting unit automatically lowers the roller so that the roller remains in horizontal contact with the workpiece, and the workpiece drives the roller to rotate smoothly.

[0011] Another object of the present invention can also be achieved by adopting the following technical solutions:

[0012] Further, in the horizontal loop, the rollers of the transfer cart adopt a lever support form. Specifically, the roller is installed on a lever arm, and through a counterweight block, the roller automatically lifts or lowers around the hinge of the support according to the horizontal height of the workpiece (metal strip).

[0013] Further, when all the idlers are in a horizontal state, the idlers are in contact with the workpiece (metal strip). At this time, under the action of the counterweight, the idlers have an upward pressing force, thereby increasing the friction between the idlers and the workpiece and making the idlers rotate smoothly. When some of the idlers cannot contact the workpiece (metal strip), the idlers will be lifted upward under the action of the counterweight and come into contact with the workpiece (metal strip) to keep the idlers rotating.

[0014] Further, when the push cart loaded with idlers is pulled open, the weight of the workpiece (metal strip) is supported by the idlers on the push cart. The workpiece (metal strip) presses the idlers to deflect downward, and the weight of the idlers is supported by two limit bolts. The workpiece (steel strip) maintains a wrap angle and contact with the idlers to keep the idlers rotating.

[0015] The second object of the present invention can be achieved by adopting the following technical solutions:

Its structural feature lies in that: an inlet idler automatic lifting structure is provided in the horizontal inlet loop, and an outlet idler automatic lifting structure is provided in the horizontal outlet loop. The inlet idler automatic lifting structure and the outlet idler automatic lifting structure are each composed of a number of automatic lifting units, and each automatic lifting unit is arranged on an idler cart; through this automatic lifting unit, the idler is driven to move up and down so that the idler remains in contact with the workpiece, forming a dynamic support structure for the idler, so that the workpiece drives the idler to keep rotating from beginning to end.

[0017] The second object of the present invention can also be achieved by adopting the following technical solutions:

[0018] Further, an inlet loop cart and a number of inlet idler carts are provided in the horizontal inlet loop, and an outlet loop cart and a number of outlet idler carts are provided in the horizontal outlet loop respectively; the inlet loop cart, the inlet idler carts and the outlet loop cart, the outlet idler carts move on the same track; the inlet loop cart and a number of inlet idler carts form an inlet push cart structure on the same track, and the inlet loop cart and a number of inlet idler carts are each provided with an automatic lifting unit; the outlet loop cart and a number of outlet idler carts form an outlet push cart structure on the same track, and the outlet loop cart and a number of outlet idler carts are each provided with an automatic lifting unit; through this automatic lifting unit, the idler is driven to move up and down so that the idler remains in contact with the workpiece, forming a dynamic support structure for the idler, so that the workpiece drives the idler to keep rotating from beginning to end.

[0019] Further, the automatic lifting unit is a structure of a balance scale lever, including a swing arm and a base. The bottom surface of the swing arm is movably connected to the base through a fulcrum to form a rotating structure. The upper surface of the left end of the swing arm is in movable contact with the idler roller, and an adjustable counterweight is arranged at the right end, forming an automatic lever structure. In practical application: the counterweight and the idler roller are installed on a swing arm. By adjusting the counterweight, the idler roller is tilted upward, and the idler roller remains in contact with the workpiece (steel strip).

[0020] Further, a left set screw is provided at the left end of the base, and a right set screw is provided at the right end. The left set screw and the right set screw are connected to the base through set screw nuts to form left and right limiting structures for the swing arm.

[0021] Further, the adjustable counterweight is connected to the right end of the swing arm through a screw rod. Nuts are provided on both sides of the adjustable counterweight. By adjusting the nuts, the position of the adjustable counterweight on the screw rod is adjusted to realize the adjustable moment arm of the counterweight.

[0022] The present invention has the following outstanding substantial effects and remarkable technical progress:

[0023] 1. The method for supporting an idler roller of a horizontal loop structure of a continuous strip production line involved in the present invention. Since idler roller automatic lifting mechanisms are respectively provided in the horizontal loops at the inlet end and the outlet end of the continuous strip production line, the idler roller is driven to move up and down through the automatic lifting unit so that the idler roller remains in contact with the workpiece, forming a dynamic support structure for the idler roller, thereby enabling the workpiece to drive the idler roller to rotate throughout the process. Therefore, it can solve the problems existing in the support structure of the transfer cart idler roller of the horizontal loop in the prior art, which are likely to cause no reduction in the friction force of the idler roller, resulting in the idler roller not rotating due to the lack of friction force and scratching the surface of the metal strip, and the problem of the surface of the metal strip being scratched by the roller due to machining errors.

Through this automatic lifting unit, the roller is driven to move up and down so that the roller remains in contact with the workpiece, forming a dynamic support structure for the roller, so that the workpiece drives the roller to rotate from beginning to end.

[0033] In this embodiment:

[0034] An inlet loop car and a number of inlet roller cars are provided in the horizontal inlet loop, and an outlet loop car and a number of outlet roller cars are provided in each of the horizontal outlet loops; the inlet loop car, the inlet roller cars, the outlet loop car, and the outlet roller cars move on the same track; the inlet loop car and a number of inlet roller cars form an inlet transfer cart structure on the same track, and an automatic lifting unit is provided in each of the inlet loop car and a number of inlet roller cars; the outlet loop car and a number of outlet roller cars form an outlet transfer cart structure on the same track, and an automatic lifting unit is provided in each of the outlet loop car and a number of outlet roller cars; through this automatic lifting unit, the roller 1 is driven to move up and down so that the roller remains in contact with the workpiece, forming a dynamic support structure for the roller, so that the workpiece drives the roller to rotate from beginning to end.

[0035] The automatic lifting unit is a balance beam structure, including a swing arm 2 and a base 4. The bottom surface of the swing arm 2 is movably connected to the base 4 through a fulcrum 10 to form a rotating structure. The upper surface of the left end of the swing arm 2 is in movable contact with the roller, and an adjustable counterweight 8 is provided at the right end, forming an automatic lever structure; in actual application: the counterweight 8 and the roller 1 are installed on a swing arm 2. By adjusting the counterweight 8, the roller 1 is tilted upward, and the roller 1 remains in contact with the workpiece (steel strip).

[0036] A left top screw 3 is provided at the left end of the base 4, and a right top screw 5 is provided at the right end. The left top screw 3 and the right top screw 5 are connected to the base 4 through top screw nuts, forming a left and right limit structure for the swing arm 2.

[0037] The adjustable counterweight 8 is connected to the right end of the swing arm 2 through a screw 6. Nuts 7 are provided on both sides of the adjustable counterweight 8. By adjusting the nuts 7, the position of the adjustable counterweight 8 on the screw 6 is adjusted to realize the adjustable moment arm of the counterweight.

[0038] The roller support method for the horizontal loop structure of the continuous strip production line involved in this embodiment is characterized in that:

[0039] 1) In the horizontal loops at the inlet end and the outlet end of the continuous strip production line, there are respectively provided roller automatic lifting mechanisms, and each roller automatic lifting mechanism is composed of several automatic lifting units. The number of automatic lifting units is the same as the number of roller cars in the horizontal loop and forms a one-to-one correspondence;

[0040] 2) The automatic lifting unit drives the roller to move up and down so that the roller remains in contact with the workpiece, forming a dynamic support structure for the roller, so that the workpiece drives the roller to rotate from beginning to end;

[0041] 3) The automatic lifting unit automatically drives the roller to move up and down according to the position change of the roller car. Specifically: when the distance between adjacent roller cars becomes smaller and the roller on the roller car is about to leave the workpiece, the automatic lifting unit automatically lifts the roller so that the roller remains in close contact with the workpiece, and the workpiece drives the roller to rotate; when the distance between adjacent roller cars becomes larger and the roller on the roller car is about to lift up the workpiece, the automatic lifting unit automatically lowers the roller so that the roller remains in horizontal contact with the workpiece, and the workpiece drives the roller to rotate smoothly.

[0042] Further, in the horizontal loop, the roller of the transfer cart adopts a lever support form. Specifically: the roller 1 is installed on a swing arm 2 (lever), and through the counterweight 8, the roller 1 can automatically lift or lower around the hinge of the support 4 along with the horizontal height of the workpiece (metal strip).

[0043] Further, when all the rollers are in a horizontal state, the rollers are all in contact with the workpiece 9 (metal strip). At this time, under the action of the counterweight 8, the roller has an upward pressing force, thereby increasing the friction force between the roller 1 and the workpiece 9 and making the roller rotate smoothly; when one of the rollers cannot contact the workpiece (metal strip), this roller will lift up under the action of the counterweight and contact the workpiece (metal strip) to keep the roller rotating.

[0044] Further, when the frame loading the roller 1 is pulled apart, the weight of the workpiece 9 (metal strip) is supported by the roller 1 on the frame. The workpiece 9 (metal strip) presses the roller 1 to deflect downward, and the weight of the roller is supported by the two limit bolts. The workpiece (steel strip) and the roller maintain a wrap angle and contact to keep the roller rotating.

[0045] In this embodiment, the roller of the transfer cart in the horizontal loop adopts a lever form. The roller 1 is installed on a lever arm 2, and through the counterweight 8, the roller 1 can be automatically lifted or lowered around the hinge of the support 4 along with the horizontal height of the metal strip. The left set screw 3 and the right set screw 5 are used as the left and right limits of the lever 2.

[0046] The counterweight 8 can adjust its position on the screw rod 6 through the nut 7, realizing adjustable counterweight arm.

[0047] The working principle of this embodiment is as follows:

[0048] In practical applications, a horizontal inlet loop is arranged at the inlet end of the continuous strip production line, and a horizontal outlet loop is arranged at the outlet end. An automatic lifting structure for inlet rollers is provided in the horizontal inlet loop, and an automatic lifting structure for outlet rollers is provided in the horizontal outlet loop. The automatic lifting structure for inlet rollers and the automatic lifting structure for outlet rollers are each composed of several automatic lifting units, and each automatic lifting unit is arranged on a roller car; specifically: an inlet loop car and several inlet roller cars are provided in the horizontal inlet loop, and an outlet loop car and several outlet roller cars are provided in the horizontal outlet loop; the inlet loop car, the inlet roller cars, the outlet loop car, and the outlet roller cars move on the same track; the inlet loop car and several inlet roller cars form an inlet transfer cart structure on the same track, and the inlet loop car and several inlet roller cars are each provided with an automatic lifting unit; the outlet loop car and several outlet roller cars form an outlet transfer cart structure on the same track, and the outlet loop car and several outlet roller cars are each provided with an automatic lifting unit; through this automatic lifting unit, the rollers are driven to move up and down to keep the rollers in contact with the workpiece, forming a dynamic support structure for the rollers, so that the workpiece drives the rollers to rotate throughout the process.

[0049] Refer to Figures 2 to 5 , several automatic lifting units are respectively arranged in the horizontal loops at the inlet end and the outlet end of the continuous strip production line, constituting several horizontal loop transfer roller car structures (in the figure, it is a combination structure of three roller cars)

[0050] Refer to Figure 2 , three roller cars are arranged together, very close to each other. The workpiece 9 (metal strip) is in line contact with the roller 1, and the friction force is very small in the natural state. When the friction force may be less than the damping of the roller 1 itself, the roller 1 does not rotate; at this time, the counterweight 8 presses the roller 1 upward through the swing arm 2 (lever), increasing the friction force between the workpiece 9 (metal strip) and the roller 1 to make the roller 1 rotate, and the workpiece 9 (metal strip) keeps closely fitting with the roller 1 in the transfer cart, so that the roller 1 keeps rotating.

[0051] Refer to Figure 3 , three roller cars are arranged together, and the horizontal height of the roller 1 in one of the transfer carts is lower than that of the roller 1 in the adjacent transfer cart. Under the action of the counterweight 8, the roller 1 in this transfer cart is lifted upward, so that the roller 1 in this transfer cart is kept at the same horizontal height as the roller 1 in other transfer carts, the workpiece 9 (metal strip) keeps closely fitting with the rollers 1 in each transfer cart, and each roller 1 keeps rotating.

[0052] Refer to Figure 4 , three roller cars are arranged together. The horizontal height of the roller 1 in one transfer cart is higher than that of the roller 1 in the adjacent transfer cart. Under the action of the weight of the workpiece 9 (metal strip), the roller 1 in this transfer cart presses downward, and the roller 1 in this transfer cart is pressed down, so that the roller 1 in this transfer cart is at the same horizontal height as the roller 1 in other transfer carts. The workpiece 9 (metal strip) is in close contact with the roller 1 of each transfer cart, and each roller 1 keeps rotating.,

[0053] Refer to Figure 5 , three roller cars are arranged together. The arrangement distance of the roller 1 between the three transfer carts is relatively far. Under the action of the self-weight of the workpiece 9 (metal strip), the roller 1 of each transfer cart presses downward. The left setscrew 3 serves as a limit for the roller 1 of the transfer cart to limit its downward pressure amplitude, so that the workpiece 9 (metal strip) is in close contact with the roller 1 of each transfer cart, and each roller 1 keeps rotating.

[0054] In this embodiment, it can also be composed of two roller cars arranged together, four roller cars arranged together, five roller cars arranged together or more than six roller cars arranged together to form a structure of multiple horizontal loop transfer roller cars.

[0055] The present invention also has the following advantages:

[0056] 1. Prevent the situation that the roller of the loop transfer cart does not rotate during work, prevent damage to the surface of the workpiece (metal strip), and improve the surface quality of the product. 2. The structure is simple, automatically adjusted, and maintenance-free in daily use.
