Description

Technical Field

[0001] This utility model relates to the technical field of crystallizer processing, and in particular to a pressure roller device for crystallizer processing. Background Technology

[0002] In metallurgical, chemical and other industrial fields, crystallizers are the core equipment for transforming materials from molten or solution states to solid crystals. As a key transmission and forming component of the crystallizer, the surface smoothness and cylindricity of the crystallizer roller directly determine the uniformity of crystallization, forming quality and production efficiency of the material inside the crystallizer. After processing or long-term use, the surface of the crystallizer roller is prone to defects such as scratches and roughness due to machining residues and material adhesion wear. If it is not precisely polished, it will lead to uneven material forming and adhesion to the roller surface during subsequent crystallization, which will seriously affect the operational stability of the crystallizer and the product qualification rate. Therefore, high-precision polishing of the crystallizer roller is a necessary process in the crystallizer processing stage. Hence, a pressure roller device for crystallizer processing is particularly needed.

[0003] However, most existing crystallizer processing roller devices can only grind the crystallizing roller in one direction, such as grinding only along the axial or circumferential direction of the crystallizing roller. This single-direction grinding will cause the grinding marks to be concentrated in the same direction. As the number of grinding times increases, the mechanical marks will continue to accumulate and gradually deepen, which will seriously affect the smoothness and flatness of the crystallizing roller surface, thereby affecting the crystallization effect of the material in the crystallizer and reducing product quality.

[0004] To address the aforementioned issues, a search revealed a patent with publication number CN219819072U that discloses a pressure roller device for crystallizer processing. The patent describes a device comprising: "a base plate, with supports fixedly mounted on both sides of the top of the base plate; a rotating plate rotatably mounted on one side of each support; a linkage frame rotatably mounted on the other side of each support; a crystallizing roller fixedly mounted between the rotating plate and the linkage frame; electric slide rails fixedly mounted inside both ends of the base plate; a sliding base slidably mounted on one side of each electric slide rail; a vertical fixing seat fixedly mounted on the top of one end of each sliding base; and a vertical fixing seat fixedly mounted on the top of the other end of each sliding base." This is a pressure roller device for crystallizer processing, equipped with a transverse grinding box. By setting up a vertical fixing seat and a transverse grinding box, the crystallizing roller can be fixed and rotated within the middle of the support. The vertical fixing seat grinds the crystallizing roller vertically, while the transverse grinding box grinds it horizontally. This effectively avoids deep mechanical marks caused by grinding in only one direction. Although the vertical fixing seat and transverse grinding box can achieve both horizontal and vertical grinding of the crystallizing roller, effectively avoiding deep mechanical marks caused by grinding in only one direction, it can only perform horizontal and vertical grinding on crystallizing rollers of the same size and specification, resulting in poor practicality.

[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a pressure roller device for crystallizer processing, including a base plate 1, a grinding mechanism 2 provided on the surface of the base plate 1, a rotating mechanism 3 provided on the surface of the base plate 1, a support plate 4 fixed on the surface of the base plate 1, a first slide 5 fitted on the surface of the base plate 1, and a second slide 6 fitted on the surface of the base plate 1. The grinding mechanism 2 includes a first threaded rod 201, a second threaded rod 202, a first motor 203, a second motor 204, a first rotating rod 205, a second rotating rod 206, a first lead screw 207, a second lead screw 208, a vertical grinding seat 209, a horizontal grinding seat 210, a third motor 211, a fourth motor 212, a vertical grinding rod 213, and a horizontal grinding rod 214. The first threaded rod 201 is rotatably connected to the side end of the base plate 1, and the second threaded rod 202 is rotatably connected to the side end of the base plate 1. The first motor 203 is mounted on the side end of the first slide 5, and the second motor 204 is mounted on the side end of the second slide 6. One end of rod 201 is fixedly connected to a first rotating rod 205; one end of the second threaded rod 202 is fixedly connected to a second rotating rod 206; the output end of the first motor 203 is fixedly connected to a first lead screw 207; the output end of the second motor 204 is fixedly connected to a second lead screw 208; one end of the first lead screw 207 is threadedly connected to a vertical grinding seat 209; one end of the second lead screw 208 is threadedly connected to a horizontal grinding seat 210; a third motor 211 is mounted on the surface of the vertical grinding seat 209; a fourth motor 212 is mounted on the surface of the horizontal grinding seat 210; and the output end of the third motor 211 is fixedly connected to a vertical grinding rod 21. 3. A transverse grinding rod 214 is fixedly connected to the output end of the fourth motor 212. When grinding the crystallizing roller 307, the first rotating rod 205 is rotated first, which drives the first threaded rod 201 to rotate. Then, the first threaded rod 201 drives the first slide block 5 to move horizontally along the surface of the base plate 1 until the vertical grinding rod 213 contacts the surface of the crystallizing roller 307. At the same time, the second rotating rod 206 is rotated, which drives the second threaded rod 202 to rotate. One end of the second threaded rod 202 drives the second slide block 6 to move horizontally until the transverse grinding rod 214 contacts the crystallizing roller 307. At this time, the first motor 203 is started. The output of the first motor 203 drives the first lead screw 207 to rotate, and the first lead screw 207 drives the vertical grinding seat 209 to move horizontally. At the same time, the third motor 211 is started, and the third motor 211 drives the vertical grinding rod 213 to rotate. The moving vertical grinding seat 209, together with the rotating vertical grinding rod 213, completes the vertical grinding of the crystallizing roller 307. Simultaneously, the second motor 204 is started, and the second motor 204 drives the second lead screw 208 to rotate. At this time, the second lead screw 208 drives the transverse grinding seat 210 to move, and at the same time, the fourth motor 212 is started to drive the transverse grinding rod 214 to rotate, thereby realizing the transverse grinding of the crystallizing roller 307.

[0019] Furthermore, one end of the first threaded rod 201 is connected through to the first slide block 5, and the first threaded rod 201 and the first slide block 5 are in a movable relationship. With the setting of the first threaded rod 201, when in use, the first slide block 5 is equipped with a ball nut that matches the first threaded rod 201. The first threaded rod 201 is fixed to the base plate 1 by a retaining ring and can only rotate. When the first threaded rod 201 rotates under the drive of the first rotating rod 205, its helical teeth generate an axial force on the nut. The first slide block 5 cannot rotate due to structural limitations, so it is driven by the nut to move horizontally along the axis of the first threaded rod 201 along the surface of the base plate 1, thereby finally adjusting the position of the vertical grinding rod 213.

[0020] Furthermore, one end of the second threaded rod 202 is connected through to the second slide block 6, and the second threaded rod 202 and the second slide block 6 are in a movable relationship. The first slide block 5 and the second slide block 6 can move in a straight line relative to or away from the base plate 1. With the setting of the second threaded rod 202, when in use, the second slide block 6 is equipped with a ball nut that matches the second threaded rod 202. The second threaded rod 202 is fixed to the base plate 1 by a retaining ring and can only rotate. When the second threaded rod 202 rotates under the drive of the second rotating rod 206, its helical teeth generate an axial force on the nut. The second slide block 6 cannot rotate due to structural limitations, so it is driven by the nut to move horizontally along the axis of the second threaded rod 202 along the surface of the base plate 1, thereby finally adjusting the position of the transverse grinding rod 214.

[0021] Furthermore, one end of the first lead screw 207 is in a movable relationship with the vertical grinding seat 209, and one end of the second lead screw 208 is in a movable relationship with the horizontal grinding seat 210. Through the arrangement of the first lead screw 207 and the second lead screw 208, during use, the vertical grinding seat 209 contains a ball nut that matches the first lead screw 207. The first lead screw 207 is fixed by a retaining ring and can only rotate. When the first motor 203 drives the first lead screw 207 to rotate, its helical teeth generate an axial force on the nut. Due to structural limitations, the vertical grinding seat 209 cannot rotate, so it moves horizontally along the axis of the first lead screw 207 with the nut, driving the vertical grinding seat 209 and the horizontal grinding seat 210. The grinding rod 213 grinds along one side of the crystallizing roller 307, thereby achieving a more comprehensive vertical grinding of the crystallizing roller 307. The transverse grinding seat 210 is equipped with a ball nut that matches the second lead screw 208. The first lead screw 207 is fixed by a retaining ring and can only rotate. When the fourth motor 212 drives the second lead screw 208 to rotate, its helical teeth generate an axial force on the nut. Due to structural limitations, the transverse grinding seat 210 cannot rotate, so it moves horizontally along the axis of the second lead screw 208 with the nut, driving the transverse grinding seat 210 and the transverse grinding rod 214 to grind along one side of the crystallizing roller 307, thereby achieving a more comprehensive vertical grinding of the crystallizing roller 307.

[0022] Furthermore, the rotating mechanism 3 includes a third threaded rod 301, a fifth motor 302, a sliding plate 303, a third rotating rod 304, a first rotating wheel 305, a second rotating wheel 306, and a crystallizing roller 307. The third threaded rod 301 is rotatably connected to the side end of the base plate 1, and the fifth motor 302 is mounted on the surface of the support plate 4. One end of the third threaded rod 301 is threadedly connected to the sliding plate 303, and the other end of the third threaded rod 301 is fixed to the third rotating rod 304. The output end of the fifth motor 302 is fixedly connected to the first rotating wheel 305, and the surface of the sliding plate 303 is rotatably connected to the second rotating wheel 306. One end of the second rotating wheel 306 is rotatably connected to the crystallizing roller 307. Through the arrangement of the third threaded rod 301, the fifth motor 302, the sliding plate 303, the third rotating rod 304, the first rotating wheel 305, the second rotating wheel 306, and the crystallizing roller 307, in use, the crystallizing roller 307 is first placed horizontally on one side of the first rotating wheel 305. The crystallizing roller 307 is moved to ensure that it is horizontally aligned with the first rotating wheel 305. Then, the crystallizing roller 307 is moved so that one end of the first rotating wheel 305 is embedded inside the crystallizing roller 307. Next, the third rotating rod 304 is rotated, and one end of the third rotating rod 304 drives the third threaded rod 301 to rotate synchronously. Since the third threaded rod 301 is connected to the slide plate 303 and forms a moving relationship, the rotating third threaded rod 301 will drive the slide plate 303 to move along the surface of the base plate 1 until the second rotating wheel 306 embedded on the surface of the slide plate 303 is also embedded inside the crystallizing roller 307, thus completing the clamping and positioning of the crystallizing roller 307. Finally, the fifth motor 302 is started, and the output end of the fifth motor 302 drives the first rotating wheel 305 to rotate. Through the interlocking transmission between the first rotating wheel 305 and the crystallizing roller 307, the crystallizing roller 307 is driven to rotate stably around its own axis. At this time, in conjunction with the grinding mechanism 2, the crystallizing roller 307 can be fully ground vertically and horizontally.

[0023] Furthermore, one end of the first rotating wheel 305 is fitted inside the crystallizing roller 307, and one end of the second rotating wheel 306 is fitted inside the crystallizing roller 307. The slide plate 303 can move linearly relative to or away from the base plate 1. One end of the third threaded rod 301 is in a movable relationship with the slide plate 303. Through the setting of the third threaded rod 301 and the first rotating wheel 305, in use, the slide plate 303 is equipped with a ball nut that matches the third threaded rod 301. The third threaded rod 301 is fixed by a retaining ring and can only rotate. When the third rotating rod 304 drives the third threaded rod 301 to rotate, its helical teeth generate an axial force on the nut. Due to structural limitations, the slide plate 303 cannot rotate, so it moves horizontally and linearly along the axis of the third threaded rod 301 with the nut. Subsequently, the slide plate 303 drives the second rotating wheel 306 to move. The first rotating wheel 305 is the transmission and clamping component of the rotating mechanism 3. It drives the crystallizing roller 307 to rotate under the drive of the fifth motor 302, and also plays a role in clamping and positioning the crystallizing roller 307 on one side.

[0024] Furthermore, the first slide block 5 and the second slide block 6 can move in a straight line relative to or away from the base plate 1. With the base plate 1 in use, the base plate 1 is used to support the various components so that the crystallizing roller 307 can be polished in the future.

[0025] Working principle: First, the crystallizing roller 307 is placed horizontally at one end of the first rotating wheel 305, ensuring that the crystallizing roller 307 and the first rotating wheel 305 are horizontally aligned. Then, the crystallizing roller 307 is moved so that one end of the first rotating wheel 305 is embedded inside the crystallizing roller 307. Next, the third rotating rod 304 is rotated, and one end of the third rotating rod 304 drives the third threaded rod 301 to rotate synchronously. Since the third threaded rod 301 is connected to the slide plate 303 and forms a moving relationship, the rotating third threaded rod 301 will drive the slide plate 303. 03. Move along the surface of the base plate 1 until the second rotating wheel 306, which is fitted onto the surface of the slide plate 303, is also embedded inside the crystallizing roller 307, completing the clamping and positioning of the crystallizing roller 307. Finally, start the fifth motor 302. The output end of the fifth motor 302 drives the first rotating wheel 305 to rotate. Through the engagement and transmission between the first rotating wheel 305 and the crystallizing roller 307, the crystallizing roller 307 is driven to rotate stably around its own axis. At this time, rotate the first rotating rod 205. The first rotating rod 205 drives the first threaded rod 201 to rotate, and then the first... The threaded rod 201 drives the first slide block 5 to move horizontally along the surface of the base plate 1 until the vertical grinding rod 213 contacts the surface of the crystallizing roller 307. At the same time, the second rotating rod 206 rotates, which drives the second threaded rod 202 to rotate. One end of the second threaded rod 202 drives the second slide block 6 to move horizontally until the transverse grinding rod 214 contacts the crystallizing roller 307. At this time, the first motor 203 is started. The output end of the first motor 203 drives the first lead screw 207 to rotate. The first lead screw 207 drives the vertical grinding seat 20 9. Move horizontally and simultaneously start the third motor 211. The third motor 211 drives the vertical grinding rod 213 to rotate. The moving vertical grinding seat 209 cooperates with the rotating vertical grinding rod 213 to complete the vertical grinding of the crystallizing roller 307. Simultaneously start the second motor 204. The second motor 204 drives the second lead screw 208 to rotate. At this time, the second lead screw 208 drives the transverse grinding seat 210 to move. At the same time, start the fourth motor 212 to drive the transverse grinding rod 214 to rotate, thereby realizing the transverse grinding of the crystallizing roller 307.
