Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of coding measurement devices, specifically an electromagnetic induction heating roller coding measurement device that is easy to maintain. Background Technology
[0002] Electromagnetic induction heating rollers are devices that use the principle of electromagnetic induction to heat the roller body. They are widely used in various industries such as plastics, rubber, textiles, and papermaking. Heating the roller body through electromagnetic induction has advantages such as fast heating speed, uniform temperature, and energy efficiency, making it particularly suitable for production processes that require rapid heating and precise temperature control. In order to accurately control the electromagnetic induction heating roller, an encoder is usually installed on the roller body or the motor shaft that drives the roller body to accurately measure the rotation angle or speed of the roller body. In order to protect the encoder from damage caused by external debris, a protective shell or cover is usually installed at the encoder mounting location.
[0003] For example, patent CN221929547U discloses an encoder protective cover, including an end cover protective cover and a shaft cylinder integrally formed at the center of the top of the end cover protective cover. A flange is integrally formed at the bottom edge of the end cover protective cover, and a rectangular boss is integrally formed at the top of the flange. An encoder protective cover body is installed on the outer wall of one side of the shaft cylinder. A rectangular opening is provided at the end of the encoder protective cover body away from the shaft cylinder, and a front sealing cover is provided at the rectangular opening of the encoder protective cover body. The protective cover body and the front sealing cover can be quickly disassembled, which facilitates the maintenance of the encoder in the encoder protective cover body. Compared with the previous structure of disassembling the protective cover and motor housing, maintenance personnel can directly access the motor encoder by simply opening the front sealing cover, which greatly shortens the maintenance time.
[0004] However, the roller coding measurement device in the above technology still has the following problems:
[0005] Although the quick-release encoder housing allows for rapid inspection and maintenance of the internal encoder, quick disassembly does not equate to quick reassembly. After completing the inspection and maintenance of the internal encoder, the small size of the encoder housing makes it difficult to insert the pins at the four corners of the protective cover into the side seats. In fact, misalignment during installation may cause deformation of the pins and side seats, making it impossible to reinstall the protective cover smoothly. This complicates subsequent installation work after encoder maintenance and delays the completion of the encoder measurement device maintenance. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides an electromagnetic induction heating roller encoding measurement device that is easy to maintain. For example, it enables rapid maintenance of the encoder and facilitates quick restoration of the encoding device after maintenance, thereby improving the overall maintenance process.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an electromagnetic induction heating roller encoding and measuring device that is easy to maintain, comprising an encoder installed on one side of a motor shaft, a protective cover installed on the outside of the encoder, the protective cover being fixedly connected to the motor shaft, a cover being connected to the side of the protective cover away from the motor shaft, a conical mounting block being fixedly connected to the side of the cover near the protective cover, the edge of the conical mounting block near the cover abutting against the inner edge of the protective cover, a sealing gasket being connected between the cover and the protective cover, connecting components being connected to the four sides of the conical mounting block, and a disassembly component being connected to the side of the connecting components away from the protective cover, the disassembly component extending to the outside of the cover.
[0008] Furthermore, the connecting assembly includes four insert rods. Each of the four sides of the tapered mounting block has a telescopic hole, which is interconnected to form a cross-shaped groove. The four insert rods are slidably connected to the four telescopic holes respectively. A connecting block is fixedly connected to the middle of the four telescopic holes. One end of each of the four insert rods located inside the four telescopic holes is fixedly connected to a telescopic spring. The other end of each of the four telescopic springs is fixedly connected to the connecting block. The four inner sidewalls of the protective cover near the end of the cover have slots. The ends of the four insert rods away from the telescopic springs are slidably connected to the four slots respectively. All four insert rods are connected to the disassembly assembly.
[0009] Furthermore, the disassembly assembly includes four pull ropes. A through hole is provided in the middle of the side of the connecting block near the cover. The end of the through hole away from the protective cover passes through the connecting block, the conical mounting block and the cover in sequence. The side wall of the through hole located inside the connecting block has four rope grooves that communicate with the four telescopic holes. One end of each of the four pull ropes is fixedly connected to the end of each of the four insert rods near the telescopic springs. The other end passes through the four telescopic springs and the four rope grooves, and is connected to the pulling assembly.
[0010] Furthermore, the pull assembly includes a main pull rope and a pull block. The ends of the four sub-pull ropes away from the insertion rod are all fixedly connected to one end of the main pull rope. The other end of the main pull rope passes through the perforation and extends to the outside of the cover before being fixedly connected to the pull block.
[0011] Furthermore, the pull block abuts against the side of the cap away from the conical mounting block.
[0012] Furthermore, the end of the insertion rod away from the telescopic spring and the side near the protective cover has a bevel.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This easy-to-maintain electromagnetic induction heating roller encoder measuring device uses a conical mounting block to quickly cover the protective cover with a cap, avoiding the problem of small caps being unable to be reinstalled on the protective cover. This allows the encoder to be quickly resealed inside the protective cover after maintenance, thus smoothly completing the post-maintenance protection operation. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Please see Figure 1 - Figure 5 An electromagnetic induction heating roller encoding and measuring device that is easy to maintain includes an encoder 2 installed on one side of a motor shaft cylinder 1. A protective cover 3 is installed on the outside of the encoder 2. The protective cover 3 is fixedly connected to the motor shaft cylinder 1. A cover 4 is connected to the side of the protective cover 3 away from the motor shaft cylinder 1. A conical mounting block 5 is fixedly connected to the side of the cover 4 near the protective cover 3. The edge of the conical mounting block 5 near the cover 4 abuts against the inner edge of the protective cover 3. A sealing gasket is connected between the cover 4 and the protective cover 3. Connecting components are connected to the four sides of the conical mounting block 5. A disassembly component is connected to the side of the connecting component away from the protective cover 3. The disassembly component extends to the outside of the cover 4.
[0023] like Figure 1 - Figure 5As shown, the maintenance-friendly electromagnetic induction heating roller encoder measuring device of this utility model is structurally similar to existing maintenance-friendly electromagnetic induction heating roller encoder measuring devices, such as the encoder protective cover disclosed in patent CN221929547U. The main improvement of this utility model is that after completing the maintenance of encoder 2, encoder 2 can be easily re-protected inside the protective cover 3, thereby smoothly completing the entire maintenance operation. Figures 1 to 5 As shown, the electromagnetic induction heating roller encoder measuring device of this utility model, which is easy to maintain, can be used by disassembling the assembly to separate the connecting assembly from the protective cover 3, removing the cover 4 and the conical mounting block 5 from the protective cover 3, thus exposing the encoder 2 inside the protective cover 3 for maintenance. After maintenance, the cover 4 and the conical mounting block 5 are brought close to the protective cover 3. At this time, the smaller end of the conical mounting block 5 can be quickly inserted into the protective cover 3, and the position between the cover 4 and the protective cover 3 can be quickly positioned, so that the connecting assembly can be directly aligned and connected with the protective cover 3, completing the quick sealing installation of the cover 4, thus smoothly completing the entire maintenance work and improving the work efficiency of the entire maintenance work.
[0024] like Figure 3 - Figure 5 As shown, the connecting assembly includes four insert rods 6. Each of the four sides of the conical mounting block 5 has a telescopic hole 501, which is interconnected to form a cross-shaped groove. The four insert rods 6 are slidably connected to the four telescopic holes 501. A connecting block 7 is fixedly connected to the middle of each of the four telescopic holes 501. One end of each insert rod 6 located within one of the four telescopic holes 501 is fixedly connected to a telescopic spring 11, and the other end of each telescopic spring 11 is fixedly connected to the connecting block 7. The four inner sidewalls of the protective cover 3 near the end of the cap 4 have slots 301. The ends of the four insert rods 6 away from the telescopic springs 11 are slidably connected to the four slots 301. All four insert rods 6 are connected to the disassembly assembly. The insert rods 6 move outward from the telescopic holes 501 via the telescopic springs 11 and are inserted into the slots 301 of the protective cover 3, thus fixing the conical mounting block 5 and the cap 4 to the protective cover 3. Combined with the other three insert rods 6, this ensures a more even force distribution between the protective cover 3 and the conical mounting block 5.
[0025] like Figure 3 - Figure 5As shown, the disassembly assembly includes four pull ropes 8. A through hole 701 is provided in the middle of the connecting block 7 near the cover 4. The end of the through hole 701 away from the protective cover 3 passes through the connecting block 7, the conical mounting block 5, and the cover 4 in sequence. Four rope grooves 702, communicating with four telescopic holes 501, are provided through the side wall of the through hole 701 within the connecting block 7. One end of each of the four pull ropes 8 is fixedly connected to the end of each of the four insert rods 6 near the telescopic spring 11, and the other end passes through the four telescopic springs 11 and the four rope grooves 702, and is connected to a pulling assembly. Using the four pull ropes 8, the four insert rods 6 can be pulled into the telescopic holes 501, thereby separating the insert rods 6 from their corresponding slots 301, allowing the conical mounting block 5 and the cover 4 to be removed from the protective cover 3.
[0026] like Figure 1 - Figure 5 As shown, the pull assembly includes a main pull rope 9 and a pull block 10. The ends of the four branch pull ropes 8 away from the insertion rod 6 are all fixedly connected to one end of the main pull rope 9. The other end of the main pull rope 9 passes through the through hole 701 and extends to the outside of the cover 4 before being fixedly connected to the pull block 10. When disassembling the cover 4, the main pull rope 9 is pulled outward from the central hole of the conical mounting block 5 and the cover 4 by the pull block 10. This simultaneously drives the four branch pull ropes 8 to retract the four insert rods 6 into the telescopic hole 501, thereby separating the four insert rods 6 from the corresponding slots 301. This allows the conical mounting block 5 and the cover 4 to be easily removed from the protective cover 3. During installation, the insert rods 6 are pulled back into the telescopic hole 501, and the conical mounting block 5 is inserted into the protective cover 3. Then, the pulling force on the insert rods 6 is released, and the telescopic spring 11 can drive the insert rods 6 to move outward from the telescopic hole 501 and insert them into the corresponding slots 301, thus completing the installation of the cover 4 on the protective cover 3. The operation is simple and quick, facilitating the rapid disassembly and installation of maintenance work.
[0027] like Figure 1 - Figure 5 As shown, the pull block 10 abuts against the side of the cover 4 away from the conical mounting block 5. When the insertion rod 6 is inserted into the slot 301, the pull block 10 abuts against the outside of the cover 4, so that after the conical mounting block 5 and the cover 4 are removed from the protective cover 3, the main pull rope 9, the branch pull rope 8 and the pull block 10 can cooperate to prevent the insertion rod 6 from popping out of the telescopic hole 501 under the action of the telescopic spring 11.
[0028] like Figure 1 - Figure 5 As shown, the end of the insertion rod 6 away from the telescopic spring 11 and the side near the protective cover 3 has a bevel. By setting the end face of the insertion rod 6 with a bevel, when installing the cover 4, the contact between the bevel and the protective cover 3 can push the insertion rod 6 into the telescopic hole 501, thus more smoothly completing the installation of the cover 4 on the protective cover 3.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
