Description

Technical Field

[0001] The utility model relates to the technical field of sealing strip molding, in particular to a transformer sealing strip molding device special for ACM rubber material. Background Art

[0002] ACM (Acrylonitrile Chloroprene Rubber) is a synthetic rubber widely used in sealing materials, hoses, and tapes due to its excellent oil and heat resistance and mechanical properties. In transformers, sealing strips prevent the leakage of insulating oil and the ingress of moisture and impurities, which is crucial for the safe operation of the transformer.

[0003] However, in the existing manufacturing process of sealing strips, most molding equipment uses hydraulic cylinders for extrusion operations. This traditional method requires waiting for the raw materials to be refilled into the mold after each extrusion before the next extrusion operation can be carried out. This makes the production process unable to achieve continuity, thereby limiting the improvement of work efficiency. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-4 The utility model provides a technical solution: a forming device for ACM rubber special transformer sealing strip, including a base 1 and a bracket 5. An extrusion device is installed on the base 1, and a forming device is installed on the bracket 5. The discharge end of the extrusion device is connected to the feed end of the forming device. The forming device includes multiple groups of rollers 9 symmetrically arranged and turning in opposite directions. A plurality of air vents are opened on the rollers 9, and a plurality of distance rings 10 arranged in the axial direction are fixedly connected to the rollers 9 by bolts. A transmission shaft 8 is fixedly arranged at both ends of the rollers 9 in the axial direction. The two ends of the transmission shaft 8 are rotatably mounted on the bracket 5. The transmission shafts 8 located on the same horizontal plane are connected by belts 7. Two groups of second motors 6 located at different horizontal planes are fixedly mounted on the bracket 5. The output shafts of the second motor 6 are respectively connected to the corresponding transmission shafts 8 for transmission. A windshield 11 is sleeved on the transmission shaft 8. The windshield 11 near the top of the bracket 5 is rotatably sleeved on the upper transmission shaft 8, and the windshield 11 near the bottom of the bracket 5 is fixedly sleeved on the lower transmission shaft 8. A plurality of cooling fans 12 are fixedly installed in the windshield 11. The extrusion device squeezes the raw material into strips. Under the drive of the belt 7, two sets of second motors 6 drive the rollers 9 at the upper and lower positions to rotate. Figure 2 In the drawing, the three upper sets of rollers 9 rotate counterclockwise, while the three lower sets of rollers 9 rotate clockwise, thereby unloading the strip material. During the unloading process, the strip material is continuously cooled by a cooling fan 12, accelerating the shaping of the strip. The strip material is then cut into several narrow strips by a distance ring 10. The distance ring 10 has an I-shaped cross-section and can cut sealing strips of fixed sizes. By adjusting the spacing between adjacent distance rings 10, sealing strips of different sizes can be cut, providing high flexibility and versatility.

[0028] Specifically, such as Figure 1 and Figure 4As shown, the extrusion device includes an extrusion barrel 2, which is fixedly connected to the base 1. A feed port 4 with a funnel-shaped structure is fixedly connected to one side of the top of the extrusion barrel 2, and a discharge port 14 with a trapezoidal contraction structure is fixedly connected to the other end of the extrusion barrel 2. A spiral auger 13 is rotatably installed in the extrusion barrel 2, and a first motor 3 is fixedly installed on one side of the extrusion barrel 2. The output shaft of the first motor 3 is in transmission connection with the spiral auger 13. The raw material is put into the extrusion barrel 2 through the feed port 4, which drives the first motor 3 to rotate the spiral auger 13, and the raw material is extruded and discharged through the discharge port 14 in the form of strips. The strips are adapted to the spacing between the distance rings 10 at both ends of the roller 9, and the raw material can be continuously extruded and discharged, making the production process continuous and improving production efficiency.

[0029] Working principle: When in use, first, the raw material is put into the extrusion cylinder 2 through the feed port 4, and the first motor 3 is driven to drive the spiral auger 13 to rotate, and the raw material is continuously extruded and discharged in the shape of strips through the discharge port 14, thereby improving production efficiency;

[0030] Secondly, under the transmission of belt 7, two sets of second motors 6 drive the rollers 9 at the upper and lower positions to rotate respectively. Figure 2 In the process of exporting, the three groups of rollers 9 on the upper side rotate counterclockwise, and the three groups of rollers 9 on the lower side rotate clockwise, thereby exporting the strip material. During the exporting process, the heat dissipation fan 12 continuously cools the rubber strip to accelerate the shaping of the rubber strip, and the distance ring 10 cuts the strip material into several narrow rubber strips.
