Description

Technical Field

[0001] This invention relates to the field of slitting machine technology, and more particularly to a tension system for winding in a slitting machine. Background Technology

[0002] A shearing machine, also known as a slitting line, slitting machine, or slitting machine, is a type of slitting equipment.

[0003] The slitting machine has many structures, including the tension mechanism.

[0004] In slitting lines for the non-ferrous metals processing industry, tensioning equipment is an essential component. Different tensioning devices are configured depending on the material, condition, thickness, and number of strips being cut. Their function is to provide appropriate winding tension to the strip. Only when the tensioning equipment provides appropriate winding tension can the coiler ensure a tightly wound finished strip.

[0005] Patent application number 201110213869.0 discloses a vacuum tension control roller system for slitting mills. This system uses a vacuum pump to create a vacuum within the roller, adsorbing the strip onto the roller and forming tension. This ensures no contact pressure on the upper surface of the strip, preventing surface damage. The lower surface of the strip is adsorbed onto the vacuum roller, with no relative movement, minimizing the possibility of damage. Because of the vacuum adsorption method, all narrow strips can achieve the same unit tension.

[0006] When the above-mentioned solution is used directly, the contact area is not wide enough because the strip is in direct contact with the surface of the slitting machine. This causes the strip to swing left and right during use, making it inconvenient to use. Moreover, the strip is subjected to a large force during use, which can easily cause the surface to sink after a period of use, thus failing to meet people's usage requirements.

[0007] Therefore, based on the inventor's extensive experience in design, development, and actual production in the relevant industry over many years, the inventor has researched and improved the existing structure and its shortcomings, and provided a tension system for winding in a slitting machine, in order to achieve a more practical purpose. Summary of the Invention

[0008] To address the issues mentioned in the background art, where the device has insufficient contact area due to the strip directly contacting the surface of the slitting machine, resulting in left-right swaying during use, making it cumbersome to use, and also causing significant stress during operation, this invention provides a tension system for winding up a slitting machine.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A tension system for winding a slitting machine includes a frame, a vacuum tension roller assembly for guiding the movement of the roll material, a drive unit, and a vacuum assembly.

[0011] There are two sets of frames, with the frame located at the rear being lower in height than the frame located at the front.

[0012] Two sets of vacuum tension roller assemblies are used to guide the movement of the roll material, and the vacuum tension roller assemblies are mounted on the frame.

[0013] There are two sets of drive units, which are mounted on the frame.

[0014] There are two sets of vacuum components, which are located on one side of the frame.

[0015] The roll material forms an S-shape as it passes through the vacuum tension roller assembly, which includes a fixed inner cylinder and a rotating outer cylinder.

[0016] The inner cylinder is fixed and installed on the frame.

[0017] The rotating outer cylinder is rotatably mounted on the fixed inner cylinder, and a cavity is formed between the rotating outer cylinder and the fixed inner cylinder. The outer surface of the rotating outer cylinder has several sets of openings that communicate with the cavity, and the outer surface of the fixed inner cylinder has several sets of strip-shaped openings that communicate with the cavity.

[0018] The drive device is connected to the rotating outer cylinder and drives the rotation of the outer cylinder;

[0019] The vacuum component is connected to the cavity.

[0020] When in use, the suction force generated by the vacuum assembly contacts the plate through the strip, cavity and opening, thereby limiting the position of the plate and preventing it from shifting left or right during movement.

[0021] This invention describes a tension system for winding a slitting machine, which employs two sets of vacuum tension roller assemblies, one high and one low. When the roll passes through, it forms an S-shape. The contact area between the roll and the two sets of vacuum tension roller assemblies is large, and the overall system is relatively stable. No deviation occurs during correction. After correction by the two sets of vacuum tension roller assemblies, the roll moves at a consistent speed, resulting in better subsequent winding effect and promising application prospects.

[0022] Preferably, the drive device includes a motor assembly and a toothed belt drive assembly:

[0023] The motor assembly is installed on the upper surface of the frame near one end;

[0024] The toothed belt drive assembly is connected to the rotating outer cylinder, and the rotating outer cylinder is driven to rotate through the toothed belt drive assembly.

[0025] In use, the motor assembly drives the outer cylinder to rotate through the toothed belt drive assembly, thereby driving the plates to move.

[0026] Toothed belt drive components can also be replaced by other transmission structures. Compared with belt drives, toothed belt drive components are more efficient and more stable.

[0027] Preferably, the vacuum assembly includes a centrifugal fan assembly and an air inlet duct:

[0028] The centrifugal fan assembly is located on one side of the vacuum assembly;

[0029] The two ends of the air intake duct are connected to the air extraction end of the centrifugal fan assembly and one end of the fixed inner cylinder, respectively, through duct connectors.

[0030] During use, the centrifugal fan assembly draws air, creating a vacuum environment inside the cavity, thus producing a vacuum and resulting in good performance.

[0031] Preferably, the outer surface of the fixed inner cylinder is provided with an elastic support assembly for supporting the rotating outer cylinder, an auxiliary support assembly for correcting the shape of the rotating outer cylinder, and a cleaning assembly for cleaning the opening.

[0032] During use, the elastic support component can provide elastic support, providing timely support when the outer cylinder deforms slightly, thus preventing excessive deformation of the outer cylinder during use and extending its service life.

[0033] Preferably, the elastic support assembly includes several sets of elastic support members, which are installed in a ring at equal intervals on the outer surface of the fixed inner cylinder.

[0034] Installing elastic support components at equal intervals provides better support.

[0035] Preferably, the elastic support includes a mounting base, an elastic element, and a mounting strip:

[0036] The mounting base is fixedly installed on the outer surface of the fixed inner cylinder;

[0037] The elastic element is embedded and fixedly installed in a strip groove on the outer surface of the mounting base;

[0038] One end of the mounting strip is fixedly connected to the elastic element, and the mounting strip is located inside the strip groove;

[0039] The mounting strip is rotatably mounted with several sets of rollers via pins, and the outer surface of the rollers is in close contact with the inner surface of the rotating outer cylinder.

[0040] This invention discloses a tension system for winding in a slitting machine. It adopts an elastic support component. During use, the roller contacts the outer surface of the fixed inner cylinder, thereby effectively supporting the fixed inner cylinder and increasing its strength. Moreover, the elasticity of the system reduces the friction experienced by the fixed inner cylinder during rotation, ensuring normal operation and good performance. It has promising application prospects.

[0041] Preferably, the auxiliary support components are in several groups, and each auxiliary support component includes a telescopic rod and a straightening plate.

[0042] The main body of the telescopic rod is fixedly installed on the outer surface of the fixed inner cylinder;

[0043] The straightening plate is fixedly installed at the telescopic end of the telescopic pole, and the end face of the straightening plate away from the telescopic pole is arc-shaped.

[0044] After a period of use, the telescopic rod is activated, driving the straightening plate to move outward, thus supporting the rotating outer cylinder. The rotating outer cylinder rotates and contacts the deformed area, achieving the correction of the rotating outer cylinder and effectively improving the performance of the rotating outer cylinder.

[0045] Preferably, the cleaning assembly includes a mounting bracket and a cleaning roller;

[0046] The mounting bracket is installed on the outer surface of the fixed inner cylinder;

[0047] The cleaning roller is rotatably mounted on the mounting frame;

[0048] The outer surface of the cleaning roller is fixedly equipped with several sets of frustum-shaped rubber columns;

[0049] Wherein, the diameter of the end face of the frustum-shaped rubber column is smaller than the inner diameter of the opening.

[0050] When in use, the frustum-shaped rubber column is inserted into the opening as it rotates, which can directly push out the debris in the opening, ensuring the suction effect and making the product more effective.

[0051] Preferably, the mounting bracket includes a mounting post and a mounting ring:

[0052] The number of mounting columns is two sets, and both sets of mounting columns are fixedly installed on the inner surface of the fixed inner cylinder;

[0053] The mounting ring is fixedly installed on the mounting column, and the mounting ring is rotatably connected to the outer surface of the cleaning roller through a bearing.

[0054] In use, the frustum-shaped rubber column is rotated and mounted on the mounting ring.

[0055] Preferably, a drive gear ring is fixedly installed on the inner surface of the rotating outer cylinder, and a transmission gear ring is fixedly installed on the outer surface of the cleaning roller, wherein the transmission gear ring meshes with the drive gear ring.

[0056] This invention discloses a tension system for winding in a slitting machine, which includes a cleaning component. During use, the rotation of the outer cylinder drives the drive gear ring to move, which in turn drives the cleaning roller to move. This allows the frustum-shaped rubber column to be inserted into the opening, directly pushing out debris from the opening, thus improving its performance and extending the service life of the tension system for winding in the slitting machine. It has good application prospects.

[0057] Compared with the prior art, the beneficial effects of the present invention are:

[0058] 1. This invention describes a tension system for winding in a slitting machine, which employs two sets of vacuum tension roller assemblies, one high and one low. When the roll passes through, it forms an S-shape. The contact area between the roll and the two sets of vacuum tension roller assemblies is large, and the overall system is relatively stable. This solves the problem that existing vacuum tension rollers have a small force area during correction, and the roll is prone to deviation due to vibration. By using two sets of vacuum tension roller assemblies for correction, the movement speed of the roll is completely limited, so that the movement speed of the roll is consistent with that of the vacuum tension roller assemblies. This results in better subsequent winding effect and has good application prospects.

[0059] 2. This invention describes a tension system for winding a slitting machine, which uses an elastic support component to support a hollow rotating outer cylinder. This not only effectively supports the force-bearing surface of the fixed inner cylinder, making the fixed inner cylinder stronger and extending the service life of the rotating outer cylinder, but also makes the rotation of the rotating outer cylinder smoother, and has good application prospects.

[0060] 3. This invention describes a tension system for winding a slitting machine, which uses an auxiliary support component to periodically correct the rotating outer cylinder. This system can reset the rotating outer cylinder when it undergoes minor deformation, improving the winding effect of the roll material, reducing the workload of relevant personnel, and greatly extending the service life of the rotating outer cylinder.

[0061] 4. This invention describes a tension system for winding in a slitting machine, which includes a cleaning component. In use, the cleaning component does not require a drive structure and can rotate with the outer cylinder, thus saving costs.

[0062] 5. This invention describes a tension system for winding in a slitting machine, which includes a cleaning component. In use, the cleaning component cleans from the inside out, ensuring unobstructed openings. This method also reduces the amount of dirt entering the vacuum equipment. Furthermore, during cleaning, it blocks unused openings, greatly enhancing the suction at other openings and effectively improving the adsorption force of the vacuum tension roller on the roll material. This invention has promising application prospects. Attached Figure Description

[0079] The roll material forms an S-shape as it passes through the vacuum tension roller assembly, which includes a fixed inner cylinder 2 and a rotating outer cylinder 3.

[0080] The fixed inner cylinder 2 is mounted on the frame 1; the rotating outer cylinder 3 is rotatably mounted on the fixed inner cylinder 2, forming a cavity between the rotating outer cylinder 3 and the fixed inner cylinder 2; the outer surface of the rotating outer cylinder 3 has several sets of openings 4 communicating with the cavity; the outer surface of the fixed inner cylinder 2 has several sets of strip-shaped openings communicating with the cavity; the driving device is connected to the rotating outer cylinder 3 and drives the rotation of the rotating outer cylinder 3; the vacuum component is connected to the cavity.

[0081] The outer surface of the fixed inner cylinder 2 is provided with a cleaning component for cleaning the opening 4 from the inside, and the cleaning component moves synchronously with the rotating outer cylinder 3.

[0082] This invention describes a tension system for winding a slitting machine, which employs two sets of vacuum tension roller assemblies, one high and one low. When the roll passes through, it forms an S-shape. The contact area between the roll and the two sets of vacuum tension roller assemblies is large, and the overall system is relatively stable. No deviation occurs during correction. After correction by the two sets of vacuum tension roller assemblies, the roll moves at a consistent speed, resulting in better subsequent winding effect and promising application prospects.

[0083] During use, the suction force generated by the vacuum component contacts the plate through the strip-shaped port, cavity and opening 4, thereby limiting the position of the plate and preventing it from shifting left or right during movement.

[0084] Example 2

[0085] Reference Figure 1-10 The difference between this embodiment and Embodiment 1 is that:

[0086] The drive unit includes a motor assembly and a toothed belt drive assembly:

[0087] The motor assembly is installed on the upper end face of the frame 1 near one end; the toothed belt drive assembly is connected to the rotating outer cylinder 3, and the rotating outer cylinder 3 is driven to rotate through the toothed belt drive assembly.

[0088] In use, the motor assembly drives the outer cylinder 3 to rotate through the toothed belt drive assembly, thereby driving the plate to move.

[0089] Toothed belt drive components can also be replaced by other transmission structures. Compared with belt drives, toothed belt drive components are more efficient and more stable.

[0090] The vacuum assembly includes a centrifugal fan assembly 5 and an air inlet duct 6.

[0091] Centrifugal fan assembly 5 is located on one side of vacuum assembly; the two ends of air inlet duct 6 are connected to the air extraction end of centrifugal fan assembly 5 and one end of fixed inner cylinder 2 respectively through duct joints.

[0092] During use, the centrifugal fan assembly 5 draws air, creating a vacuum environment inside the cavity, thus producing a vacuum and resulting in good performance.

[0093] The outer surface of the fixed inner cylinder 2 is provided with an elastic support assembly for supporting the rotating outer cylinder 3, an auxiliary support assembly for correcting the shape of the rotating outer cylinder 3, and a cleaning assembly for cleaning the opening 4.

[0094] During use, the elastic support component can provide elastic support, providing timely support when the rotating outer cylinder 3 deforms slightly, thus preventing excessive deformation of the rotating outer cylinder 3 during use and improving its service life.

[0095] The elastic support assembly includes several sets of elastic support members, which are installed in a ring at equal intervals on the outer surface of the fixed inner cylinder 2.

[0096] Installing elastic support components at equal intervals provides better support.

[0097] The elastic support includes a mounting base 7, an elastic element 8, and a mounting strip 9: the mounting base 7 is fixedly installed on the outer surface of the fixed inner cylinder 2; the elastic element 8 is embedded and fixedly installed in the strip groove opened on the outer surface of the mounting base 7; one end of the mounting strip 9 is fixedly connected to the elastic element 8, and the mounting strip 9 is located inside the strip groove;

[0098] Among them, several sets of rollers 10 are rotatably mounted on the mounting strip 9 via pins, and the outer surface of the rollers 10 is in close contact with the inner surface of the rotating outer cylinder 3.

[0099] This invention discloses a tension system for winding in a slitting machine. It adopts an elastic support component. During use, the roller 10 contacts the outer surface of the fixed inner cylinder 2, thereby effectively supporting the fixed inner cylinder 2 and making the fixed inner cylinder 2 stronger. Moreover, the elasticity of the system reduces the friction force experienced by the fixed inner cylinder 2 during rotation, which does not affect its normal operation. It has good performance and promising application prospects.

[0100] Example 3

[0101] Reference Figure 1-10 The difference between this embodiment and Embodiment 2 is that:

[0102] The auxiliary support components consist of several sets, including telescopic rods 11 and straightening plates 12.

[0103] The main body of the telescopic rod 11 is fixedly installed on the outer surface of the fixed inner cylinder 2; the straightening plate 12 is fixedly installed on the telescopic end of the telescopic rod 11, and the end face of the straightening plate 12 away from the telescopic rod 11 is arc-shaped.

[0104] After a period of use, the telescopic rod 11 is activated, which drives the straightening plate 12 to move outward, thereby supporting the rotating outer cylinder 3. The rotating outer cylinder 3 rotates and contacts the deformed position, realizing the correction of the rotating outer cylinder 3, which can effectively improve the use effect of the rotating outer cylinder 3.

[0105] A pressure sensor is fixedly installed at the bottom of the main body of the telescopic rod 11, which can detect the force.

[0106] The cleaning assembly includes a mounting bracket and a cleaning roller 13;

[0107] The mounting bracket is installed on the outer surface of the fixed inner cylinder 2; the cleaning roller 13 is rotatably mounted on the mounting bracket; wherein, a number of sets of frustum-shaped rubber columns 14 are fixedly installed on the outer surface of the cleaning roller 13;

[0108] Among them, the diameter of the end face of the frustum-shaped rubber column 14 is smaller than the inner diameter of the opening 4.

[0109] The frustum-shaped rubber column 14 is inserted into the opening 4 without getting stuck, and can be easily pulled out.

[0110] During use, the frustum-shaped rubber column 14 is inserted into the opening 4 as it rotates, which can directly push out the debris in the opening 4, ensuring the suction effect and making the use more effective.

[0111] The mounting bracket includes mounting posts 15 and mounting rings 16.

[0112] There are two sets of mounting columns 15, and both sets of mounting columns 15 are fixedly installed on the inner surface of the fixed inner cylinder 2.

[0113] The mounting ring 16 is fixedly mounted on the mounting column 15, and the mounting ring 16 is rotatably connected to the outer surface of the cleaning roller 13 through a bearing.

[0114] In use, the frustum-shaped rubber column 14 is rotatably mounted on the mounting ring 16.

[0115] A drive gear ring 17 is fixedly installed on the inner surface of the rotating outer cylinder 3, and a transmission gear ring 18 is fixedly installed on the outer surface of the cleaning roller 13. The transmission gear ring 18 meshes with the drive gear ring 17.

[0116] When the vacuum tension roller assembly guides the movement of the roll material, the frustum-shaped rubber column 14 is inserted into the opening 4 that does not contact the roll material, thereby greatly enhancing the suction force at other openings 4.

[0117] This invention describes a tension system for winding in a slitting machine, which includes a cleaning component. During use, the rotation of the outer cylinder 3 drives the drive gear ring 17 to move, which in turn drives the gear ring 18 to rotate, thereby driving the cleaning roller 13 to move. This allows the frustum-shaped rubber column 14 to be inserted into the opening 4, directly pushing out debris from the opening 4, thus improving its performance and extending the service life of the tension system for winding in the slitting machine. It has good application prospects.
