Description

Technical Field

[0001] This utility model relates to the field of industrial roller component processing and repair technology, specifically to an internal spiral guide roller rust removal device. Background Technology

[0002] In existing internal spiral guide roller equipment, the spiral guide plate is usually fixedly connected to the inner wall of the roller body and cannot be disassembled or separated. After long-term use, rust and impurities easily adhere to the surface of the spiral guide plate. Due to the narrow space between the spiral guide plate and the inner wall of the roller body, and the spiral structure of the spiral guide plate, traditional rust removal methods are difficult to penetrate to clean all parts of its surface, resulting in the inability to completely remove the rust from the surface of the spiral guide plate. The accumulation of rust not only affects the guiding and conveying effect of the spiral guide plate on materials, but also reduces the cleanliness of the roller body and the spiral guide plate as a whole, thus adversely affecting the subsequent normal use of the equipment. Therefore, an internal spiral guide roller rust removal device is proposed. Utility Model Content

[0003] This utility model proposes an internal spiral guide roller rust removal device. The ball screw driven by the motor drives the connecting rod to move along the spiral surface, ensuring that the rust removal operation can cover all parts of the spiral guide plate, thereby achieving a complete and thorough cleaning of the surface of the spiral guide plate, improving the cleanliness of the roller body and the spiral guide plate as a whole, and ensuring the normal use of the equipment in the future.

[0004] According to one aspect, at least one embodiment of the present invention provides an internal spiral guided drum rust removal device, comprising: a drum body, a spiral guide plate disposed on the inner wall of the drum body, a sliding rod welded and fixed to the outer wall of the spiral guide plate, a sliding groove formed on the inner wall of the drum body, the sliding rod slidably connected inside the sliding groove, the spiral guide plate being disposed on the inner wall of the drum body through the sliding connection between the sliding rod and the sliding groove, a connecting ring fixedly connected to one end of the sliding rod, a connecting plate disposed on one side of the connecting ring, a rubber insert fixedly connected to the inner side of the connecting plate, an installation groove formed on the connecting ring, the rubber insert being inserted and fixedly fixed inside the installation groove, a motor disposed at one end of the connecting plate, a ball screw fixedly connected to the power transmission end of the motor, a ball screw drive block being drivenly connected to the outer end of the ball screw drive block, a rotating block being rotatably sleeved on the outside of the ball screw drive block, a connecting rod fixedly connected to the outer end of the rotating block, and the connecting rod being disposed on the spiral guide plate.

[0005] For example, at least one embodiment of the present invention provides an internal spiral guide roller rust removal device, which further includes: an auxiliary block fixedly connected to the outer end of the roller body, a limiting rod movable inside the auxiliary block, a limiting groove formed on the surface of the sliding rod, and the limiting rod inserted into the limiting groove through the sliding groove.

[0006] For example, at least one embodiment of the present invention provides an internal spiral guide roller rust removal device, which further includes: a spring wound around the outer wall of the limiting rod, one end of the spring being fixedly connected to the limiting rod, and the other end of the spring being fixedly connected to the auxiliary block.

[0007] For example, at least one embodiment of the present invention provides an internal spiral guide roller rust removal device, which further includes: the outer end of the limiting rod is arranged in a ring shape, and the surface of the outer end of the limiting rod is provided with anti-slip texture.

[0008] For example, at least one embodiment of the present invention provides an internal spiral guide roller rust removal device, which further includes: the outer wall of the rubber insert and the inner wall of the mounting groove are in contact with each other, and four sets of the rubber insert are provided on the connecting plate.

[0009] For example, at least one embodiment of the present invention provides an internal spiral guide roller rust removal device, which further includes: the motor is rotatably connected inside the connecting plate through a bearing sleeve block, and the motor is connected to a power source through a wire.

[0010] For example, at least one embodiment of the present invention provides an internal spiral guide roller rust removal device, which further includes: a rubber handle fixedly connected to the outer end of the connecting rod, and the rubber handle is symmetrically attached to the surface of the spiral guide plate.

[0011] For example, at least one embodiment of the present invention provides an internal spiral guide roller rust removal device, which further includes: an array of rust removal pads provided on the outer wall of the rubber handle, the rust removal pads being distributed in a conical shape on the surface of the outer wall of the rubber handle.

[0012] The working principle and beneficial effects of this utility model are as follows: The internal spiral guide roller rust removal device slides the spiral guide plate to the inner wall of the roller body through the sliding rod and the sliding groove, and uses the connecting ring to realize the synchronous movement of the sliding rod, so that the spiral guide plate can be separated from the inside of the roller body and completely exposed, providing sufficient operating space for rust removal operation; at the same time, the connecting plate is fixed by the rubber plug and the mounting groove of the connecting ring, which can quickly realize the assembly of the motor and ball screw structure with the connecting ring. When the motor drives the ball screw to rotate, the ball screw transmission block moves parallel to the ball screw. With the rotational connection of the rotating block and the ball screw transmission block, the connecting rod can move against its outer wall under the guidance of the spiral guide plate. During the above-mentioned structural assembly process, the ball screw driven by the motor drives the connecting rod to move along the spiral surface, ensuring that the rust removal operation can cover all parts of the spiral guide plate, thereby achieving a complete and thorough cleaning of the spiral guide plate surface, improving the cleanliness of the roller body and the overall spiral guide plate equipment, and ensuring the normal use of the equipment in the future.

[0021] Refer to the instruction manual appendix Figure 1-5A spiral-guided drum rust removal device includes: a drum body 1, a spiral guide plate 2 disposed on the inner wall of the drum body 1, a sliding rod 4 welded and fixed to the outer wall of the spiral guide plate 2, a groove 3 formed on the inner wall of the drum body 1, the sliding rod 4 slidably connected inside the groove 3, the spiral guide plate 2 being disposed on the inner wall of the drum body 1 through the sliding connection between the sliding rod 4 and the groove 3, a connecting ring 5 fixedly connected to one end of the sliding rod 4, a connecting plate 7 disposed on one side of the connecting ring 5, a rubber insert 8 fixedly connected to the inner side of the connecting plate 7, an installation groove 6 formed on the connecting ring 5, the rubber insert 8 being inserted and fixedly fixed inside the installation groove 6, a motor 9 disposed at one end of the connecting plate 7, a ball screw 10 fixedly connected to the power transmission end of the motor 9, and a ball screw drive block 1 connected to the outer end of the ball screw 10. 1. A rotating block 12 is externally mounted on the ball screw drive block 11. A connecting rod 13 is fixedly connected to the outer end of the rotating block 12. The connecting rod 13 is mounted on the spiral guide plate 2. During the rust removal operation, the sliding rod 4 is first released from its fixed position on the slide groove 3. After the release, the connecting ring 5 is pulled. The connecting ring 5 causes the sliding rod 4 to slide inside the slide groove 3. Since the sliding rod 4 is fixedly connected to the spiral guide plate 2, the sliding of the sliding rod 4 causes the spiral guide plate 2 to detach from the inside of the drum body 1, so that the spiral guide plate 2 is completely exposed, which facilitates the subsequent rust removal operation. At this time, the connecting plate 7 is installed on one end surface of the connecting ring 5, so that the rubber insert 8 is aligned with the mounting groove 6 on the connecting ring 5 and forcefully inserted. The rubber insert 8 undergoes a certain deformation during the insertion process. After the insertion is completed, the rubber insert... Under the action of its own elastic restoring force, column 8 fits tightly against the inner wall of mounting groove 6, achieving the effect of positioning and initial fixation, ensuring that there is no relative movement between connecting plate 7 and connecting ring 5; at this time, motor 9 is started, and the output shaft of motor 9 drives ball screw 10 to rotate. When ball screw 10 rotates, the threads on its surface mesh with the threads inside ball screw transmission block 11. Since ball screw transmission block 11 is restricted by rotating block 12 and connecting rod 13, it cannot rotate with ball screw 10. Therefore, the rotation of ball screw 10 will drive ball screw transmission block 11 to move parallel to the outer wall of ball screw 10; at this time, since ball screw transmission block 11 and rotating block 12 are set in a rotating connection manner, ball screw transmission block 11 moves parallel to the outer wall of ball screw 10. When the rod 10 moves horizontally, the rotating block 12 can rotate accordingly based on the contact between the connecting rod 13 and the surface of the spiral guide plate 2. This allows the connecting rod 13 to move along the outer wall of the spiral guide plate 2 under its guidance, thereby achieving the application and cleaning of the rust remover on the surface of the spiral guide plate 2. The above structure, by making the spiral guide plate 2 detachable and using a motor-driven ball screw structure to move the connecting rod 13 along the surface of the spiral guide plate 2, solves the problem that the surface of the spiral guide plate 2 cannot be completely cleaned during the general rust removal operation of the drum body 1. It can comprehensively clean all parts of the spiral guide plate 2, improve the overall cleanliness of the drum body 1 and the spiral guide plate 2, and ensure the normal use of the equipment in the future.

[0022] Then, an auxiliary block 16 is fixedly connected to the outer end of the roller body 1. A limiting rod 17 is movable inside the auxiliary block 16. A limiting groove 18 is opened on the surface of the slide rod 4. The limiting rod 17 passes through the slide groove 3 and is inserted into the limiting groove 18. By sliding the limiting rod 17 on the auxiliary block 16, one end of the limiting rod 17 is driven to insert into the limiting groove 18. At this time, the slide rod 4 will form a fixed structure on the slide groove 3. The limiting rod 17 restricts the movement of the slide rod 4, thereby ensuring the fixed effect of the spiral guide plate 2 inside the roller body 1 under normal use, and preventing the spiral guide plate 2 from sliding during the operation of the roller body 1, which would affect the guiding and conveying of materials.

[0023] Subsequently, a spring 19 is wound around the outer wall of the limiting rod 17. One end of the spring 19 is fixedly connected to the limiting rod 17, and the other end of the spring 19 is fixedly connected to the auxiliary block 16. Through the elastic properties of the spring 19, the spring 19 always applies a spring force to the limiting rod 17 in the direction of the slide rod 4, so that the limiting rod 17 can always be inserted into the limiting groove 18, ensuring the connection stability between the limiting rod 17 and the limiting groove 18. Even if the device is subjected to slight vibration, the limiting rod 17 will not easily disengage from the limiting groove 18, further improving the fixing reliability of the spiral guide plate 2 inside the roller body 1.

[0024] Next, the outer end of the limiting rod 17 is arranged in a ring shape, and the surface of the outer end of the limiting rod 17 is provided with anti-slip texture. By pulling the ring structure at the outer end of the limiting rod 17, the limiting rod 17 is driven to overcome the elastic force of the spring 19 and move away from the slide rod 4, so that the limiting rod 17 is separated from the limiting groove 18. Then, the slide groove 3 and the slide rod 4 are changed to a movable connection, which plays a role in the subsequent disassembly and rust removal of the spiral guide plate 2. The whole operation process is simple and labor-saving, and it is convenient for operators to quickly complete the disassembly work.

[0025] At this point, the outer wall of the rubber insert 8 is in contact with the inner wall of the mounting groove 6, and four sets of rubber inserts 8 are provided on the connecting plate 7. This distribution method can make the force between the connecting plate 7 and the connecting ring 5 more uniform, avoiding excessive local force that could damage the connection structure. The four sets of rubber inserts 8 work together to fix the connecting ring 5 to the connecting plate 7. This fixing effect is to ensure that the connection between the connecting plate 7 and the connecting ring 5 is not affected when the motor 9 is working, and to ensure that the power of the motor 9 can be stably transmitted to the ball screw 10, so that the rust removal operation can be carried out smoothly.

[0026] Next, the motor 9 is rotatably connected inside the connecting plate 7 via a bearing sleeve, and the motor 9 is connected to the power supply via wires. This structure ensures that the motor 9 will not affect the fixing effect between the connecting ring 5 and the connecting plate 7 when it starts, so that the ball screw 10 can run normally. At this time, the connecting ring 5 and the connecting plate 7 will be fixed to the external bracket by some existing auxiliary fixing parts such as some support seats or fixed seats. The external bracket provides stable support for the entire rust removal mechanism, preventing the connecting ring 5 and the connecting plate 7 from shaking during the rust removal process, which would affect the rust removal accuracy and effect.

[0027] Secondly, a rubber handle 14 is fixedly connected to the outer end of the connecting rod 13. The rubber handle 14 is symmetrically fitted onto the surface of the spiral guide plate 2. This arrangement ensures that when the ball screw drive block 11 moves parallel, the rubber handle 14 is guided by the spiral guide plate 2 and remains in contact with the surface of the spiral guide plate 2, thus simultaneously removing rust from both sides of the spiral guide plate 2 and enhancing the rust removal effect. Furthermore, due to the material properties of the rubber handle 14, it can be deformed and positioned on both sides of the spiral guide plate 2. Even if the surface of the spiral guide plate 2 has a certain curvature or uneven structure, the rubber handle 14 can still fully contact the surface of the spiral guide plate 2 through its own deformation, ensuring thorough rust removal.

[0028] Finally, an array of rust-removing pads 15 are provided on the outer wall of the rubber handle 14. The rust-removing pads 15 are distributed in a conical shape on the outer surface of the rubber handle 14. The conical structure of the rust-removing pads 15 increases the contact pressure with the surface of the spiral guide plate 2, thereby improving the rust removal effect. The rust-removing pads 15 are made of conical sponges soaked in rust-removing liquid. The sponge material has good water absorption and retention properties, which can absorb a sufficient amount of rust-removing liquid. During the movement of the rubber handle 14, the rust-removing liquid can continuously act on the rust on the surface of the spiral guide plate 2. At the same time, the friction of the conical sponge can remove the rust. This arrangement can better improve the rust removal effect, ensuring that the rust on the surface of the spiral guide plate 2 can be completely removed, restoring the original surface condition of the spiral guide plate 2.

[0029] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
