TECHNICAL FIELD

[0001] The utility model relates to tension control technical field more particularly, relate to a kind of floating roller device and tension control mechanism. BACKGROUND

[0002] In the processing and transportation process of film base material category roll stock, to ensure that it maintains a certain degree of stretch flatness, it is usually necessary to control the tension by a tension adjusting structure such as a floating roller, so as to maintain the stretching state of the base material and thus ensure its processing quality. In the prior art, a common floating roller device is composed of a driving mechanism, an oscillating arm and a floating roller. The floating roller body is oscillated by the driving mechanism to achieve the purpose of tension adjustment. However, for such a common floating roller device, the tension adjustment accuracy is often affected during the specific debugging process due to the influence of the weight of the floating roller itself.

[0003] Therefore, the prior art urgently needs a floating roller device that reduces the influence of the weight of the floating roller itself and improves the tension adjustment accuracy. SUMMARY

[0004] The utility model aims at overcoming at least one of the above-mentioned deficiencies of the prior art, providing a floating roller device that reduces the influence of the weight of the floating roller itself, improves the tension adjustment accuracy and improves the tension adjustment effect.

[0005] The technical solution adopted by the utility model is a floating roller device, which comprises a main wallboard, a floating roller mounting mainboard, a floating roller driving mechanism, a floating roller body and a counterweight assembly. The floating roller mounting mainboard is rotatably installed on the main wallboard. The floating roller driving mechanism drives the floating roller mounting mainboard to rotate. The end portion of the floating roller body is installed on one side of the rotation center of the floating roller mounting mainboard. The counterweight assembly is arranged on the other side of the rotation center of the floating roller mounting mainboard. In this application, the floating roller driving mechanism drives the floating roller mounting mainboard to rotate, thereby driving the floating roller body to oscillate around the rotation center as the oscillation base point to adjust the tension accordingly. The counterweight assembly is arranged on the opposite side of the floating roller body, which is beneficial to counterbalance according to the weight of the floating roller body to avoid the influence of the weight of the floating roller body on the accuracy. Through the balance of the counterweight assembly, the driving degree of the floating roller driving mechanism can be accurately matched with the tension adjustment degree, thereby improving the tension adjustment accuracy of the floating roller device. In addition, the counterweight assembly can also counterbalance according to the weight of other possible errors, and the debugging method has multiple modes, which is suitable for different application scenarios. It is worth noting that the floating roller device comprises the main wallboards on both sides, the floating roller mounting mainboards, the floating roller driving mechanisms and the floating roller bodies. The end portions of the floating roller bodies are installed on the floating roller mounting mainboards on the corresponding sides. The floating roller mounting mainboards are rotatably installed on the main wallboards on the corresponding sides and are driven by the floating roller driving mechanisms on the corresponding sides to oscillate.

[0006] Further, the counterweight assembly comprises a counterweight rod and a weight formed on the counterweight rod. Further, the counterweight rod is installed on the side of the floating roller installation main plate opposite to the floating roller body, and the weight is detachably sleeved on the counterweight rod. Further, the weight of the counterweight rod is less than the weight of the floating roller body; through the counterweight of the weight, the configuration is more flexible, and different specifications of weights can be used in combination to adjust the balance.

[0007] Further, the floating roller installation main plate is further provided with a mounting groove, the mounting groove has a plurality of mounting positions, and the end of the counterweight rod is adjustably mounted on the mounting groove. Further, the mounting groove is an elongated mounting groove, and the length direction of the mounting groove is the length direction of the floating roller installation main plate. Further, the end of the counterweight rod is connected with a locking screw, and the locking screw cooperates with the locking of the counterweight rod relative to the position of the mounting groove. Or, the end of the counterweight rod is mounted on the mounting groove through a locking structure, and the locking structure can release or fasten the end of the corresponding side counterweight rod. That is, the position of the counterweight rod can be adjusted relative to the floating roller installation main plate; according to actual needs, the counterweight rod can be mounted on the corresponding mounting position. On the one hand, the position of the counterweight rod can be adjusted in the length direction of the floating roller installation main plate (i.e. the swing arm direction), and the position of the counterweight rod can be finely adjusted according to the actual weight and counterweight to achieve the best debugging result. Compared with the weight, the counterweight rod can be further adjusted to improve the adjustability. On the other hand, the position of the counterweight rod can be adjusted according to the needs, which is suitable for different scenes.

[0008] Further, the ratio of the distance between the rotation center of the floating roller installation main plate and the floating roller body to the distance between the rotation center and the counterweight assembly is greater than 1.3, and the distance between the rotation center and the counterweight assembly is less than the distance between the rotation center and the floating roller body. Further, the ratio of the distance between the rotation center and the floating roller body to the distance between the rotation center and the counterweight assembly is between 1.5 and 3. Further, when the counterweight assembly is a counterweight rod, the distance between the rotation center and the counterweight assembly represents the distance between the rotation center and the counterweight rod. That is, the distance between the rotation center and the floating roller body is D1, the distance between the rotation center and the counterweight assembly is D2, and the ratio of D1 to D2 is greater than 1.3, and further, the ratio of D1 to D2 is between 1.5 and 3. By setting the distance ratio, sufficient counterweight balance space is reserved, and at the same time, the floating roller device occupies a larger swing space, which is beneficial to the arrangement of other components inside the main wall plate.

[0009] Further, the swing angle range of the floating roller body relative to the horizontal plane is -30°-30°. That is, the total angle range of the rotation center is 60°.

[0010] Further, limit blocks are arranged above and / or below the main wall plate on the side of the main wall plate where the floating roller installation main plate is arranged with the counterweight assembly. The limit blocks assist in limiting the rotating position of the floating roller installation main plate, reduce the load on the corresponding driving mechanism, avoid damage to the driving mechanism, and improve the service life of the overall floating roller device.

[0011] Further, a bumper pad is arranged on the upper end and / or lower end of the side of the floating roller installation main plate where the counterweight assembly is arranged. The bumper pad is arranged in cooperation with the limit blocks to avoid direct impact between the floating roller installation main plate and the limit blocks due to excessive rotation.

[0012] Further, a rotating shaft is also included, which is installed on the corresponding side main wall plate through the floating roller installation main plate, and forms the rotating center of the floating roller installation main plate. When the driving mechanism drives the floating roller installation main plate to rotate, the floating roller installation main plate rotates around the rotating shaft as the axis, and the side of the floating roller installation main plate close to the floating roller body forms a swing arm to drive the floating roller body to swing. The counterweight assembly is located on the side of the floating roller main plate opposite to the floating roller body, and at least balances the weight of the floating roller body.

[0013] Further, the end of the rotating shaft passes through the floating roller installation main plate and is fixed to the main wall plate through a quick-release fixing plate, which is detachably fixed to the main wall plate. The rotating shaft is arranged to rotate relative to the quick-release fixing plate, and is fixed relative to the floating roller installation main plate. The output end of the driving mechanism is detachably connected to the floating roller installation main plate. Since the rotating shaft only provides the rotating center, it does not require a complex cooperating component structure. On this basis, the quick-release fixing plate is used to install the rotating shaft to the main wall plate, so that the main body structure formed by the floating roller installation main plate, the floating roller body, the counterweight assembly, and the rotating shaft can be easily detached from the wall plate. This is conducive to immediate disassembly, maintenance, and replacement, and improves the use stability of the corresponding device.

[0014] Further, the floating roller driving mechanism includes a telescopic cylinder installed on the main wall plate. The floating roller main plate extends upward to form an adapter, and the output end of the telescopic cylinder is rotatably connected to the upper end adapter of the floating roller main plate. Further, in the length direction of the floating roller installation main plate, the adapter is located between the floating roller body and the rotating shaft (rotating center).

[0017] Compared with the prior art, the floating roller device has the advantages that the self-weight influence of the floating roller is reduced, the tension adjustment precision is improved, and the tension adjustment effect is improved. BRIEF DESCRIPTION OF DRAWINGS
