Description

Technical Field

[0001] This utility model relates to the technical field of filter membrane production equipment, and more specifically, to a slitting and conveying device for filter membrane production. Background Technology

[0002] As a core separation element in water treatment, biomedicine, food processing and other fields, the "slitting and conveying" process of filter membranes directly determines the dimensional accuracy and appearance quality of the products. With the expansion of filter membrane application scenarios, the market demand for narrow and ultra-thin filter membranes is increasing, which puts forward higher requirements for the operating accuracy of the slitting and conveying device - it is necessary to achieve high-speed and stable rotation of the slitting blade shaft to avoid filtration performance failure due to membrane material damage.

[0003] When the slitting blade shaft rotates at high speed, the shearing force between the blade assembly and the membrane material, as well as the operating friction of the bearing itself, will generate periodic vibrations. These vibrations are directly transmitted to the frame through the bearing housing. Because traditional devices often use a rigid connection between the bearing housing and the frame, lacking an effective vibration buffer structure, the vibrations can cause frame resonance, leading to radial runout of the blade shaft. This runout causes the shearing position between the slitting blade and the membrane material to shift, resulting in rough edges and serrated notches on the slit membrane, thus leading to a high defect rate.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] (II) Technical Solution To address the aforementioned problems, the specific technical solution adopted by this utility model is as follows: A slitting and conveying device for filter membrane production includes a frame, a bearing housing, and a slitting blade shaft disposed within the bearing housing. An air bladder ring is provided at the connection between the bearing housing and the frame. The inner wall of the air bladder ring is fixedly connected to the outer circumferential surface of the bearing housing, and the outer wall is fixedly connected to the inner wall of the mounting groove of the frame. A sealed air chamber is formed inside the air bladder ring, and an inflation nozzle is provided.

[0007] Furthermore, the airbag ring is made of oil-resistant rubber.

[0008] Furthermore, the air chamber of the airbag ring is provided with an annular metal skeleton, which is embedded between the inner and outer sidewalls of the airbag ring, and the skeleton has through holes evenly distributed on it.

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments.

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0018] According to an embodiment of the present invention, a slitting and conveying device for filter membrane production is provided.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-3 As shown, the slitting and conveying device for filter membrane production according to an embodiment of the present utility model includes a frame 1, a bearing seat 2, and a slitting blade shaft 3 disposed in the bearing seat 2. An airbag ring 4 is provided at the connection between the bearing seat 2 and the frame 1. The inner side wall of the airbag ring 4 is fixedly connected to the outer peripheral surface of the bearing seat 2, and the outer side wall is fixedly connected to the inner wall of the mounting groove of the frame 1. A sealed air chamber is formed inside the airbag ring 4 and an inflation nozzle 5 is provided.

[0020] In one embodiment, the "airbag ring 4 between the bearing housing 2 and the frame 1" can directly target and buffer the local vibration generated by the high-speed rotation of the slitting blade shaft 3. The airbag ring 4 can absorb the periodic vibration of the blade shaft in real time through the elastic deformation of the internal sealed air cavity, thus preventing the vibration from being directly transmitted to the frame 1 through the bearing housing 2 and causing resonance.

[0021] Specifically, the airbag ring 4 is made of oil-resistant rubber.

[0022] In one embodiment, it exhibits excellent aging resistance, significantly reducing maintenance frequency and costs.

[0023] Specifically, the air chamber of the airbag ring 4 is provided with an annular metal skeleton 6, which is embedded between the inner and outer side walls of the airbag ring 4, and through holes are evenly distributed on the skeleton.

[0024] In one embodiment, excessive deformation of the rubber can be limited, thereby reducing the stiffness decay rate of the airbag ring 4.

[0025] Specifically, the outer circumferential surface of the bearing housing 2 is provided with an annular groove, the inner sidewall of the airbag ring 4 is embedded in the groove and fixed by the vulcanization process; the inner wall of the mounting groove of the frame 1 is provided with an annular boss 7, and the outer sidewall of the airbag ring 4 is provided with an annular groove, with the boss and groove having an interference fit.

[0026] In one embodiment, the annular groove on the outer circumference of the bearing housing 2 is vulcanized and fixed to the inner wall of the airbag ring 4, so that the rubber and metal form a "molecular-level bond" to avoid loosening of the inner connection caused by vibration.

[0027] Specifically, it also includes a pressure sensor 8 and a pressure relief valve 9. The pressure sensor 8 is connected to the air chamber of the airbag ring 4 to detect the internal air pressure, and the pressure relief valve 9 is connected in series with the inflation nozzle 5.

[0028] In one embodiment, the pressure sensor 8 is used to detect the internal air pressure, while the pressure relief valve 9 automatically opens when the air pressure exceeds a preset threshold.

[0029] Specifically, there are two airbag rings 4, which are symmetrically arranged at both ends of the bearing housing 2 along the axial direction.

[0030] In one embodiment, the bearing housing 2 is ensured to be subjected to balanced forces at both ends.

[0031] Specifically, the slitting shaft 3 is equipped with a circular blade assembly, and a slitting motor 10 is installed at the end of the slitting shaft 3, and the slitting motor 10 is installed on the side surface of the frame 1.

[0032] In one embodiment, the slitting motor 10 is mounted on the end of the slitting blade shaft 3 and fixed to the side surface of the frame 1, forming a direct drive structure of "motor-blade shaft", which has significant advantages in transmission efficiency and response speed.

[0033] Working principle: When the slitting blade shaft 3 rotates at high speed, the shearing force between the slitting blade assembly and the filter membrane, and the friction of the blade shaft bearing will generate periodic vibration. Since the inner side of the airbag ring 4 is fixed in the annular groove on the outer circumference of the bearing seat 2 through the vulcanization process, the vibration will be transmitted to the airbag ring 4 first. The sealed air chamber inside the airbag ring 4 absorbs the vibration energy through "elastic deformation". The annular metal skeleton 6 inside the air chamber of the airbag ring 4 plays the role of "rigid support": on the one hand, it restricts the "creep deformation" of the oil-resistant rubber due to long-term pressure, and avoids the stiffness of the airbag ring 4 from decreasing with the use time. On the other hand, the uniform through holes on the skeleton ensure smooth airflow inside the air chamber, avoids the "shock absorption blind zone" caused by uneven local air pressure, and ensures that the vibration attenuation effect at all points in the circumference of the airbag ring 4 is consistent, and ensures that the vibration of the slitting blade shaft 3 is stable and controlled in the whole circumference.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
