This equipment is widely used in metal processing and sheet metal processing, and is crucial for improving sheet metal processing efficiency and quality.

[0003] Among them, during the process of cutting the coiled sheet material, the high-speed slitting machine needs to use a tensioning device to tension the coiled sheet material to improve the cutting accuracy, thereby improving the quality of the coiled sheet material after cutting and winding.

[0005] However, since the position where the tension generating device exerts pressure on the coiled sheet is relatively concentrated, the coiled sheet is easily damaged during transportation under pressure, thereby affecting the final product quality of the coiled sheet. Utility Model Content

[0009] The machine body is provided with two seats for mounting the two positioning structures respectively, and the two seats are distributed along the transport direction of the coiled sheet;

[0042] The following is combined with Figure 1-3 This application is described in further detail.

[0043] Example 1:

[0044] An embodiment of the present application discloses a tensioning device for a high-speed slitting machine, which is used to keep the coiled sheet material in a tensioned state during transportation, thereby facilitating subsequent cutting of the coiled sheet material to obtain high-quality products.

[0045] Reference Figure 1 The tensioning device includes a body 1, two positioning structures 2, and a mounting platform 3. The body 1 provides a mounting support for the tensioning device and can also transport and move the coiled sheet 4 above it. The positioning structures 2 can tension the coiled sheet 4 during transportation and movement, and can keep the coiled sheet 4 in a tensioned state during transportation and movement. The mounting platform 3 also provides a mounting support for the tensioning device, making the layout of the tensioning device more reasonable and making the installation of the tensioning device more convenient.

[0046] The machine body 1 is fixedly mounted on the ground and has an overall rectangular parallelepiped structure. Two bases 11 for mounting the positioning structure 2 are provided on the top of the machine body 1. The two bases 11 are distributed along the length of the machine body 1 and have different vertical heights. The two ends of the machine body 1 in the lengthwise direction are an inlet 12 for the incoming rolled sheet material 4 and an outlet 13 for the outgoing rolled sheet material 4. The base 11 near the outlet 13 is positioned lower than the base 11 near the inlet 12. In this embodiment, the rolled sheet material 4 is preferably transported into the inlet 12 in a direction parallel to the lengthwise direction of the machine body 1 and is also transported out of the outlet 13 in a direction parallel to the lengthwise direction of the machine body 1.

[0047] Reference Figure 1 and Figure 2 The positioning structure 2 includes a positioning roller 21, a vacuum suction machine 22 and a driving component 23.

[0048] The positioning roller 21 is generally cylindrical in structure. Once installed on the corresponding base 11, it can rotate relative to the base 11. The rotation axis of the positioning roller 21 coincides with its own axis and is parallel to the width of the machine body 1. After the two positioning rollers 21 are installed on the two bases 11, the position of the positioning roller 21 near the outlet end 13 is lower than the position of the positioning roller 21 near the inlet end 12, and the vertical height difference between the two positioning rollers 21 is less than the radius of the positioning roller 21. In this embodiment, since the structure of the base 11 with the above-mentioned functions is common in the prior art, it will not be described in detail here, and only a brief representation is provided in the accompanying drawings.

[0049] The positioning roller 21 has a cavity 211 inside, and the shape of the cavity 211 is also cylindrical, and the axis of the cavity 211 coincides with the axis of the positioning roller 21; the radial surface of the positioning roller 21 is also provided with a plurality of suction holes 212, and the two ends of the suction holes 212 are respectively connected to the cavity 211 and the space outside the radial direction of the positioning roller 21, and the plurality of suction holes 212 are evenly distributed on the radial surface of the positioning roller 21.

[0050] The vacuum suction machine 22 is mounted on one side of the machine body 1 in the width direction and includes a main body 221 and an air pipe 222. The main body 221 is fixedly mounted on the ground. One end of the air pipe 222 is fixedly connected to the main body 221, and the other end of the air pipe 222 is fixedly connected to the base 11. The end of the air pipe 222 closest to the base 11 is able to communicate with the cavity 211 inside the corresponding positioning roller 21. During the rotation of the positioning roller 21 relative to the corresponding base 11, the air pipe 222 maintains communication with the cavity 211 inside the corresponding positioning roller 21. In this embodiment, since the vacuum suction machine 22 is a common prior art, it will not be described in detail here, and only a brief description is provided in the accompanying drawings.

[0051] The driving assembly 23 includes a first driving member 231, a coupling 234, a driving wheel 232 and a synchronous belt 233. The mounting platform 3 is fixedly installed on the ground and is located on the same side of the machine body 1 as the vacuum suction machine 22 for mounting and fixing the first driving member 231.

[0052] The driving wheel 232 is rotatably mounted on the top of the machine body 1 on the side close to the mounting platform 3, and is located on the side of the corresponding positioning roller 21 away from the other positioning roller 21, and the rotation axis of the driving wheel 232 is parallel to the axis of the corresponding positioning roller 21; the outer surface of the driving wheel 232 in the radial direction is distributed with teeth 5, and the outer surface of the positioning roller 21 in the radial direction close to the end of the mounting platform 3 is also distributed with the same teeth 5, and the inner surface of the synchronous belt 233 is also distributed with the same teeth 5, and the teeth 5 on the driving wheel 232 are aligned with the teeth 5 on the positioning roller 21 along the length direction of the machine body 1; the synchronous belt 233 is simultaneously wound around the corresponding driving wheel 232 and the positioning roller 21, and the teeth 5 on the synchronous belt 233 are simultaneously engaged with the teeth 5 on the driving wheel 232 and the teeth 5 on the positioning roller 21; at this time, the driving wheel 232 rotates relative to the machine body 1, and the corresponding positioning roller 21 can be driven to rotate synchronously relative to the corresponding base body 11 through the synchronous belt 233.

[0053] The first driving member 231 is fixedly mounted on the top of the mounting platform 3. The ends of the coupling 234 are fixedly connected to the corresponding first driving member 231 and the corresponding driving wheel 232, respectively. The first driving member 231 can drive the driving wheel 232 to rotate relative to the machine body 1 through the coupling 234. In this embodiment, the first driving member 231 is preferably a motor. Since the motor and coupling 234 are both common in the prior art, they will not be described in detail here, and both are only briefly shown in the drawings.

[0054] The two first driving members 231 drive the driving wheels 232 to rotate synchronously and in opposite directions, so that the two positioning rollers 21 can rotate synchronously and in opposite directions, and the speed at which the first driving members 231 drive the positioning rollers 21 to rotate matches the transportation speed of the coiled sheet 4 on the machine body 1.

[0055] During the process of transporting the coiled sheet 4 on the machine body 1, it will be wound on the radial surfaces of the two positioning rollers 21 at the same time, and the coiled sheet 4 will be wound on the positioning roller 21 near the outlet end 13 first and then on the positioning roller 21 near the inlet end 12 along its own transport direction.

[0056] During the transportation of the coiled sheet 4, the two vacuum suction machines 22 remain in operation to extract the gas in the two cavities 211, so that the positioning roller 21 can apply suction to the part of the coiled sheet 4 that contacts its surface through multiple suction holes 212, so that the coiled sheet 4 can remain in contact with the surface of the positioning roller 21, thereby keeping the coiled sheet 4 taut during transportation.

[0057] The implementation principle of the tensioning device of a high-speed slitting machine in the embodiment of the present application is as follows:

[0058] The coiled sheet 4 is first wound on the two positioning rollers 21 in a tensioned state, and then the two vacuum suction machines 22 are controlled to operate to keep the coiled sheet 4 in a tensioned state on the two positioning rollers 21 through suction;

[0059] Afterwards, during the transportation and movement of the coiled sheet 4 on the machine body 1, the two vacuum suction machines 22 continue to operate, and at the same time, the two first driving members 231 can drive the two positioning rollers 21 to rotate according to the transportation and movement speed of the coiled sheet 4, so that the coiled sheet 4 can remain in a tensioned state during the transportation and movement, thereby improving the subsequent cutting effect of the coiled sheet 4, thereby improving the quality of the final coiled sheet 4 product.

[0060] Example 2:

[0061] Reference Figure 1 and Figure 3 The difference between this embodiment and embodiment 1 lies in the mounting platform 3 , on which are mounted two lifting assemblies 31 for controlling the height position of the first driving member 231 , and the two lifting assemblies 31 correspond one-to-one to the two first driving members 231 .

[0062] Reference Figure 3 The lifting assembly 31 includes a lifting platform 311 and a second driving member 312 , and the first driving member 231 is fixedly installed on the top of the corresponding lifting platform 311 .

[0063] The lifting platform 311 is vertically slidably connected to the mounting platform 3. The second driving member 312 is installed inside the mounting platform 3 and below the lifting platform 311. The second driving member 312 can drive the lifting platform 311 to slide relative to the mounting platform 3. In this embodiment, the second driving member 312 is preferably a cylinder; since cylinders are common in the prior art, they will not be described in detail here and are only briefly illustrated in the drawings.

[0064] After the first driving member 231 is installed and fixed on the top of the corresponding lifting platform 311, the axis of the output end of the first driving member 231 will be located in the same vertical plane as the axis of the corresponding driving wheel 232; in the process of controlling the second driving member 312 to drive the lifting platform 311 to slide relative to the mounting platform 3, the axis of the output end of the corresponding first driving member 231 can coincide with the axis of the corresponding driving wheel 232, thereby making it convenient for the staff to install the coupling 234 between the first driving member 231 and the driving wheel 232, and at the same time improving the stability of the coupling 234 in transmitting power between the two.

[0065] The implementation principle of the tensioning device of a high-speed slitting machine in the embodiment of the present application is as follows:

[0066] During the process of installing the tensioning device, the staff first controls the second driving member 312 to drive the lifting platform 311 to slide and rise and fall, so that the corresponding first driving member 231 is coaxial with the corresponding driving wheel 232, and then installs the coupling 234 between the corresponding first driving member 231 and the corresponding driving wheel 232. This can not only make the installation process of the tensioning device more convenient, but also improve the stability of the power transmission of the coupling 234, thereby improving the control accuracy of the first driving member 231 driving the corresponding positioning roller 21 to rotate through the coupling 234.

[0067] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
