Description

Technical Field

[0001] This invention belongs to the field of furnace roller processing technology, and specifically relates to a furnace roller surface spraying treatment equipment. Background Technology

[0002] In many industrial production fields, especially in processes such as metal rolling and heat treatment, furnace rolls play a crucial role. As a key component for carrying and conveying materials, the surface quality of furnace rolls directly affects the stability of the production process and the quality of products. With the continuous development of industrial technology, the requirements for the surface performance of furnace rolls are also increasing. In order to meet the needs of different production processes, extend the service life of furnace rolls, and reduce production costs, it is usually necessary to spray the surface of furnace rolls. By spraying a special coating on the surface of furnace rolls, the wear resistance, corrosion resistance and other properties of the furnace roll surface can be effectively improved, and the adaptability of furnace rolls in harsh working environments can be enhanced. Therefore, furnace roll surface spraying equipment has emerged and become an important piece of equipment to ensure the performance of furnace rolls and improve industrial production efficiency and quality.

[0003] Existing furnace roller surface coating processes involve cleaning the roller surface before coating, reducing work efficiency. Most cleaning methods rely on manual wiping or compressed air blowing, which has limited effectiveness and fails to completely remove stubborn stains and fine particles. These residual contaminants affect the adhesion between the coating and the roller surface during coating, leading to easy peeling and reduced coating quality and service life. Furthermore, most existing furnace roller surface coating equipment uses fixed spray nozzles, making it difficult to adjust the spraying distance in real-time according to the actual specifications and surface condition of the roller. This results in uneven coating thickness, especially when processing rollers of different diameters. Uneven coating thickness affects the consistency of the roller surface performance, thus impacting the overall quality stability of the production process. Therefore, there is an urgent need to design a furnace roller surface coating equipment to address these issues. Summary of the Invention

[0019] This specific embodiment is a furnace roller surface spraying treatment device, the structural schematic diagram of which is shown below. Figures 1-13 As shown, the furnace roller surface spraying treatment equipment includes a frame 1. A spindle box 2 and a tailstock 3 are respectively set at the top two ends of the frame 1. A three-jaw chuck for fixing the furnace roller is set on the opposite side of the spindle box 2 and the tailstock 3. The spindle box 2 and the tailstock 3 are mounted on the frame 1 through an X-axis moving module. During operation, one end of the furnace roller that needs to be surface sprayed is placed in the three-jaw chuck on the spindle box 2, and the other end is placed in the three-jaw chuck on the tailstock 3. The clamping action of the three-jaw chuck fixes both ends of the furnace roller, realizing the stable installation of the furnace roller on the equipment. It should be noted that the spindle box 2, the tailstock 3, the three-jaw chuck and the X-axis moving module are all existing technologies and will not be described in detail here.

[0020] In this embodiment, as Figure 1 and Figure 13As shown, the furnace roller surface spraying treatment equipment also includes a support assembly 4. The support assembly 4 is installed on the top of the frame 1 and is arranged in two sets between the main spindle box 2 and the tailstock 3. The support assembly 4 is used to support the furnace roller. The support assembly 4 includes a support seat 401 installed on the top of the frame 1. A connecting wheel frame 402 is fixedly connected to the top of the support seat 401. Two support rollers 403 are rotatably connected inside the connecting wheel frame 402. The furnace roller to be surface sprayed is hoisted to the equipment by a lifting device. The connecting parts at both ends of the furnace roller are placed between the two support rollers 403. The furnace roller is supported by the support seat 401, the connecting wheel frame 402 and the support rollers 403. The furnace roller is then clamped and fixed by a three-jaw chuck through the movement of the main spindle box 2 and the tailstock 3. As a preferred embodiment of this invention, the support base 401 is also mounted on the frame 1 via an X-axis moving module, which can adjust the spacing between the two sets of support components 4 to accommodate the support placement of furnace rollers of different lengths. The support base 401 can be configured as a telescopic adjustable support base, which can adjust the height of the connecting wheel frame 402 and the support roller 403. Since the dimensions of the connecting parts of furnace rollers of different specifications are also different, the height adjustment of the connecting wheel frame 402 and the support roller 403 can ensure the proper assembly of the furnace roller with the three-jaw chuck on the main shaft box 2 and the tailstock 3.

[0021] In this embodiment, as Figure 4 As shown, the furnace roller surface spraying treatment equipment also includes a cleaning unit 5. The cleaning unit 5 is located above the frame 1 and between the two sets of support components 4. It is used to clean the surface of the furnace roller. The cleaning unit 5 includes a mounting plate 51, a feeding group 52 and a receiving group 53 installed at both ends of the top of the mounting plate 51. An attachment mechanism is provided on the top of the mounting plate 51 between the feeding group 52 and the receiving group 53. The attachment mechanism is used to attach the cleaning tape to the surface of the furnace roller. A moving mechanism 7 is used to drive the mounting plate 51 to move along the axial direction of the furnace roller. The moving mechanism 7 can be a linear module, a linear module, a screw mechanism, etc., and its main function is to... The effect is to provide a linear motion output with high control precision. The cleaning belt roll is installed on the feeding group 52, and one end of the cleaning belt roll is wound up by the receiving group 53, so that the cleaning belt passes around the bottom part of the furnace roller. The attachment mechanism ensures that the cleaning belt has sufficient contact area with the surface of the furnace roller. The moving mechanism 7 drives the mounting plate 51 to move automatically along the axial direction of the furnace roller. At the same time, the feeding group 52 and the receiving group 53 work together automatically to realize the continuous supply and winding of the cleaning belt, effectively removing dust, impurities and other contaminants from the surface of the furnace roller, improving the cleanliness of the furnace roller surface, and providing good surface conditions for subsequent spraying treatment.

[0022] In this embodiment, in the cleaning unit of the furnace roller surface spraying treatment equipment, a suitable material and type of cleaning belt can be selected according to the actual condition of the furnace roller, cleaning requirements, etc., such as non-woven cleaning belt, cotton cleaning belt, synthetic fiber cleaning belt, etc.

[0023] In this embodiment, as Figure 4 and Figure 5 As shown, the attachment mechanism includes a connecting seat 54 fixedly connected to the middle of the top of the mounting plate 51. Two rotating plates 55 are rotatably connected to the connecting seat 54. A limiting wheel 56 is rotatably connected to the end of the rotating plate 55 away from the connecting seat 54. A receiving groove 561 for accommodating the cleaning strip is formed on the outer surface of the limiting wheel 56 along the circumferential direction. Multiple second ball bearings 562 are rotatably connected to the outer sides of both ends of the rotating plate 55 near the furnace roller. Sliding grooves 511 are symmetrically formed on both sides of the top of the mounting plate 51 on the connecting seat 54. A moving block 571 is slidably connected in the sliding groove 511. A support plate 57 is hinged between the moving block 571 and the adjacent rotating plate 55. A third elastic element 572 is fixedly connected between the side of the moving block 571 away from the connecting seat 54 and the inner wall of the sliding groove 511. The third elastic element 572 can be a spring. Before the cleaning unit 5 starts working, the furnace roller is placed on the support assembly 4 from top to bottom using a hanger, so that the furnace roller contacts the limiting wheel 56. The third elastic element 572 pushes the moving block 571 to slide in the slide groove 511. The support plate 57 keeps the rotating plate 571 at a suitable opening angle, and the cleaning belt is placed inside the receiving groove 561 on the limiting wheel 56, so that the limiting wheel 56 on the rotating plate 571 always keeps in contact with the furnace roller, limiting the position of the cleaning belt and ensuring that the cleaning belt has sufficient length to contact the furnace roller, thereby improving the cleaning effect on the furnace roller. The setting of the second ball 562 on the limiting wheel 56 reduces the friction between the limiting wheel 56 and the furnace roller when the mounting plate 51 drives the attachment mechanism to move, so that the limiting wheel 56 can move more smoothly along the furnace roller axis, ensuring the cleaning effect.

[0024] In this embodiment, as Figure 5 and Figure 6As shown, the attachment mechanism also includes an attachment wheel 563. Both ends of the attachment wheel 563 are rotatably connected to connecting plates 564. Arc-shaped grooves 565 are also provided on the outer sides of both ends of the limiting wheel 56. A guide arc rod 566 is fixedly connected inside the arc-shaped groove 565. One end of the connecting plate 564 is slidably connected inside the arc-shaped groove 565 and sleeved on the outer side of the guide arc rod 566. A second elastic element 567 is sleeved between the bottom end of the connecting plate 564 and the inner wall of the arc-shaped groove 565, and on the outer side of the guide arc rod 566. The second elastic element 567 can be a spring. When the furnace roller approaches the cleaning unit 5, the attachment wheel 563 first contacts the surface of the furnace roller. Due to the reaction force of the furnace roller surface, the attachment wheel 563 will be subjected to outward pressure. The pressure is transmitted through the connecting plate 564, causing the connecting plate 564 to slide along the guide arc rod 566 in the arc groove 565 while compressing the second elastic element 567. As the second elastic element 567 is compressed, the elastic force generated by it reacts on the connecting plate 564, thereby making the attaching wheel 563 press more tightly against the surface of the furnace roller. In this process, the attaching wheel 563 always maintains full contact with the surface of the furnace roller under the action of elastic force, tightly adhering the cleaning belt to the surface of the furnace roller. With the positioning function of the limiting wheel 56, it ensures that the cleaning belt adheres well to the surface of the furnace roller, completing the cleaning work on the surface of the furnace roller, effectively improving the cleaning effect, and ensuring that contaminants on the surface of the furnace roller can be removed more thoroughly.

[0025] In this embodiment, as Figure 7 , Figure 8 and Figure 9 As shown, the feeding assembly 52 includes a feeding roller frame 521 fixedly connected to the top of the mounting plate 51. Feeding connecting shafts 522 are rotatably connected to both sides of the feeding roller frame 521. A feeding tray 523 is detachably installed between the two feeding connecting shafts 522, and the feeding connecting shafts 522 and the feeding tray 523 are detachably connected by bolts. The receiving assembly 53 includes a receiving roller frame 531 fixedly connected to the top of the mounting plate 51. A receiving connecting shaft 532 is rotatably connected to both sides of the receiving roller frame 531. A receiving tray 533 is detachably installed between the two receiving connecting shafts 532, and the receiving connecting shafts 532 and the receiving tray 533 are detachably connected by bolts. The detachable installation of the feeding tray 523 and the receiving tray 533 allows operators to quickly and easily disassemble and install new feeding trays and receiving trays after the cleaning belt is used up or when different types of cleaning belts need to be replaced, reducing equipment downtime and improving work efficiency.

[0026] Furthermore, such as Figure 9As shown, a linkage assembly is provided between one of the receiving connecting shafts 532 and the frame 1. The linkage assembly includes a first pulley 534 fixedly sleeved on the outside of one of the receiving connecting shafts 532 and a drive box 535 fixedly connected to the mounting plate 51. A first rotating shaft and a second rotating shaft are rotatably connected to the drive box 535. One end of the first rotating shaft is located outside the drive box 535 and fixedly connected to a second pulley 536. A belt 537 is driven between the second pulley 536 and the first pulley 534. The other end of the first rotating shaft... The first end of the second rotating shaft is located inside the drive housing 535 and is fixedly connected to a first bevel gear 538. One end of the second rotating shaft is located inside the drive housing 535 and is fixedly connected to a second bevel gear 539, which meshes with the first bevel gear 538. The other end of the second rotating shaft is located outside the drive housing 535 and is fixedly connected to a gear 5310. A rack 5311 is fixedly connected to the bottom of the frame 1 at the location of the gear 5310. The gear 5310 meshes with the rack 5311. The rack 5311 is positioned along the moving direction of the moving mechanism 7. The mounting plate 51 is longer than the length of the furnace roller to be coated. When the moving mechanism 7 drives the mounting plate 51 to move along the axial direction of the furnace roller, the mounting plate 51 drives the drive box 535 on it to move together. Since the gear 5310 on the drive box 535 meshes with the rack 5311 installed on the frame, the gear 5310 is driven to rotate during the movement of the mounting plate 51. The rotation of the gear 5310 drives the second rotating shaft fixedly connected to it to rotate, and the second bevel gear 539 on the second rotating shaft rotates accordingly. Through the second bevel gear 5310, the second bevel gear 539 rotates. 39 meshes with the first bevel gear 538, driving the first bevel gear 538 and the first rotating shaft connected thereto, as well as the second pulley 536 on the first rotating shaft, to rotate. Through the belt 537, the first pulley 534 is driven to rotate. The first pulley 534 transmits power to the receiving connecting shaft 532, which in turn drives the receiving disc 533 to rotate, gradually winding up the used cleaning belt. This achieves linkage between the receiving group 53 and the mounting plate 51, ensuring that the cleaning belt can be wound up in time during the cleaning process and maintaining the continuity of the cleaning work.

[0027] Furthermore, to prevent the feeding tray 523 from rotating arbitrarily during the feeding process, such as Figure 7 and Figure 8As shown, multiple positioning holes 5231 are evenly spaced along the circumferential direction on the outer walls of both sides of the feeding tray 523. A guide groove is provided between each pair of adjacent positioning holes 5231. A sleeve 524 is fixedly connected to the feeding roller frame 521 at the positioning holes 5231. A first ball bearing 526 is disposed inside the sleeve 524, with part of the first ball bearing 526 passing through the sleeve 524 and engaging in the positioning hole 5231. A first elastic element 525, which can be a spring, is also disposed inside the sleeve 524. One end of the first elastic element 525 abuts against the outside of the first ball bearing 526, and the other end abuts against the inner wall of the sleeve 524. When the cleaning unit 5 starts working, the cleaning belt is pulled, and the feeding tray 523 is pulled and rotates. The first ball bearing 526 slides along the guide groove as the feeding disc 523 rotates, thanks to the positioning holes 5231 and guide grooves. As the feeding disc rotates, when the first ball bearing 526 slides to the next positioning hole 5231, it is engaged in the positioning hole 5231 again under the elastic force of the first elastic element 525, thus achieving phased positioning of the feeding disc's rotation angle. As the cleaning work progresses, the feeding disc 523 continues to rotate, and the first ball bearing 526 continuously switches between the positioning holes 5231 and guide grooves under the action of the first elastic element 525, ensuring that the feeding disc 523 can rotate in an orderly manner when subjected to the pulling force of the cleaning belt, thereby achieving continuous and stable feeding of the cleaning belt.

[0028] In this embodiment, as Figure 10As shown, the fixed-distance spraying unit 6 includes a movable plate 61 disposed below the mounting plate 51. A fixed column 62 is fixedly connected to one end of the top of the movable plate 61, and a third ball bearing 621 is rotatably connected to the top of the fixed column 62. A spray nozzle 63 is mounted on the other end of the top of the movable plate 61 via a bracket. The spray nozzle 63 is connected to the paint supply equipment. The height of the top of the spray nozzle 63 is lower than the height of the top of the third ball bearing 621. A guide reset mechanism is provided between the movable plate 61 and the mounting plate 51. When the furnace roller is not installed in the furnace roller surface spraying treatment equipment, the movable plate 61 is in its initial position relative to the mounting plate 51 under the action of the guide reset mechanism. At this time, the third ball bearing 621 at the top of the fixed column 62 and the spray nozzle 63 are in their respective initial height states. When the furnace roller is installed, the third ball bearing 621 first contacts the surface of the furnace roller. The reaction force will push the fixed column 62 and the moving plate 61, causing the moving plate 61 to move relative to the mounting plate 51 against the elastic force of the guide reset mechanism, thereby adjusting the position of the spray nozzle 63. This ensures that the distance between the spray nozzle 63 and the surface of the furnace roller is consistent when performing surface spraying treatment on furnace rollers of different specifications, thus maintaining the stability of the distance between the spray nozzle 63 and the surface of the furnace roller, improving the accuracy and quality of spraying. When spraying the furnace roller, the friction is reduced by the contact between the third ball bearing 621 and the surface of the furnace roller, which helps with movement. As a preferred embodiment of this example, the bracket of the spray nozzle 63 can be replaced with a height adjustment mechanism, such as an electric telescopic rod or a manual screw adjustment assembly, which can adjust the initial height of the spray nozzle 63 according to different spraying processes and spraying materials, thereby improving the spraying quality.

[0029] In this embodiment, as Figure 10As shown, the guide reset mechanism includes a guide post 65 fixedly connected to the bottom of the mounting plate 51. The moving plate 61 is slidably engaged with the guide post 65. A retaining post 64 is fixedly connected to the bottom of the moving plate 61. A fixing frame 66 is also fixedly connected to the bottom of the mounting plate 51. A through hole is provided on the fixing frame 66 corresponding to the retaining post 64. The bottom end of the retaining post 64 passes through the through hole. A fourth elastic element 67 is sleeved between the fixing frame 66 and the moving plate 61 and outside the retaining post 64. The fourth elastic element 67 can be a spring. When the fixed-distance spraying unit 6 is not working, the moving plate 61 is in the initial position relative to the mounting plate 51 under the elastic force of the fourth elastic element 67. At this time, the bottom end of the retaining post 65 passes through the through hole on the fixing frame 66. When the third ball 621 contacts the furnace roller and is subjected to the reaction force of the furnace roller, the force is transmitted to the moving plate 61. The moving plate 61 slides along the guide post 65, and at the same time drives the moving plate 61 to move along the guide post 65. The retaining post 65 moves in the through hole of the fixing frame 55 to compress the fourth elastic element 67. During this process, the fourth elastic element 67 stores elastic potential energy. The position of the moving plate 61 changes with the force of the furnace roller, thereby adjusting the distance between the spray nozzle and the furnace roller. During the spraying operation, the fourth elastic element 67 is continuously compressed, and its elastic force acts on the third ball 621 through the moving plate 61, so that the third ball 621 always fits tightly against the surface of the furnace roller, ensuring the stability of the spraying distance during the spraying process. When the furnace roller is removed from the surface spraying equipment, the force of the furnace roller on the third ball 621 disappears, and the elastic potential energy stored in the fourth elastic element 67 is released, pushing the moving plate 61 to move along the guide post 65 to the initial position. The retaining post 65 moves accordingly in the through hole of the fixing frame 66 until the moving plate 61 returns to the initial position, preparing for the next fixed-distance spraying.

[0030] A clamping and positioning assembly 68 is provided between the fixed frame 66 and the frame 1. The clamping and positioning assembly 68 is used to clamp and lock the position of the retaining post 64. The clamping and positioning assembly 68 includes a limiting frame 681 fixedly connected to the bottom of the fixed frame 66 and symmetrically arranged on both sides of the retaining post 64. A moving rod 682 is slidably connected to the limiting frame 681. The moving rod 682 has a polygonal cross-section to prevent the moving rod 682 from deflecting during movement. A clamping block 683 is fixedly connected to one end of the moving rod 682 near the retaining post 64, and the other end of the moving rod 682 is rotatably connected to... There is a roller 685, and a limit block is fixedly sleeved on the moving rod 682 near the roller 685. A fifth elastic element 684 is sleeved between the limit block and the limit frame 681 and outside the moving rod 682. The fifth elastic element 684 can be a spring. The clamping and positioning assembly 68 also includes two guide plates 686 fixedly connected to the top of the frame 1. The inner side of the two guide plates 686 near the clamping and positioning assembly 68 is designed to be flared. When the mounting plate 51 drives the fixed-distance spraying unit 6 to move and spray, the clamping and positioning assembly 68 gradually approaches the guide plates 686 on the frame 1. 86. As the moving roller 685 first contacts the inner side of the flared design of the guide plate 686, due to the flared design of the guide plate 686, during continued movement, the guide plate 686 exerts an inward squeezing force on the roller 685. This causes the roller 685 to drive the moving rod 682 to slide and compress the fifth elastic element 684 on the limiting frame 681. The moving rod 682 then drives the clamping block 683 to gradually approach the retaining post 64, so that the clamping block 683 moves exactly to both sides of the retaining post 64. The clamping block 683 tightly clamps the retaining post 64, locking the position of the retaining post 64. The clamping and positioning component 68 is used to fix the position of the moving plate 61, thereby keeping the distance between the spray nozzle 63 and the furnace roller stable. The function of the clamping and positioning component 68 is to lock the position of the moving plate 61 during the spraying process. Because the positions of the fixing column 62 and the spray nozzle 63 are different, when spraying the position near the end of the furnace roller, the fixing column 62 and the third ball bearing 621 have moved to the position of disengaging from the furnace roller. At this time, the position of the moving plate 61 is locked under the action of the clamping and positioning component 68, so that the spray nozzle 63 can still be kept in the current position to continue the spraying operation.

[0031] Working principle: During use, the furnace roller to be coated is hoisted to the equipment using a lifting device. The connecting parts at both ends of the furnace roller are placed between the two support rollers 403 of the two sets of support components 4. The furnace roller is supported by the support base 401, the connecting wheel frame 402 and the support rollers 403. One end of the furnace roller is placed in the three-jaw chuck on the spindle box 2 and the other end is placed in the three-jaw chuck on the tailstock 3. The clamping action of the three-jaw chuck fixes both ends of the furnace roller, achieving stable installation of the furnace roller on the equipment. The cleaning belt roll is installed on the feeding tray 523 of the feeding group 52. One end of the cleaning belt roll is wound up through the receiving tray 533 of the receiving group 53, so that the cleaning belt passes around the bottom part of the furnace roller. The furnace roller contacts the limiting wheel 56. The third elastic element 572 pushes the moving block 571 to slide in the slide groove 511. The support plate 57 keeps the rotating plate 55 at a suitable opening angle. The cleaning belt is placed inside the receiving groove 561 on the limiting wheel 56, so that the limiting wheel 56 always keeps in contact with the furnace roller and limits the position of the cleaning belt. Then the attachment wheel 563 first contacts the surface of the furnace roller. The reaction force from the surface causes the attaching wheel 563 to experience outward pressure. This pressure is transmitted through the connecting plate 564, causing the connecting plate 564 to slide along the guide arc rod 566 in the arc groove 565 while simultaneously compressing the second elastic element 567. This makes the attaching wheel 563 press more tightly against the surface of the furnace roller, firmly adhering the cleaning belt to the surface of the furnace roller. The moving mechanism 7 drives the mounting plate 51 to move automatically along the axial direction of the furnace roller. At the same time, the feeding group 52 and the receiving group 53 work together automatically to achieve continuous supply and winding of the cleaning belt, effectively removing dust, impurities and other contaminants from the surface of the furnace roller, and improving the cleanliness of the furnace roller surface. Furthermore, during the installation of the furnace roller, the third ball bearing 621 first contacts the surface of the furnace roller. Due to the reaction force of the furnace roller surface, it pushes the fixed column 62 and the moving plate 61, causing the moving plate 61 to overcome the elasticity of the guide reset mechanism and move relative to the mounting plate 51, thereby adjusting the position of the spray nozzle 63. This ensures that the distance between the spray nozzle 63 and the surface of the furnace roller is consistent when performing surface spraying treatment on furnace rollers of different specifications. The spray nozzle 63 is connected to the paint supply equipment to perform spraying treatment on the surface of the furnace roller. When the mounting plate 51 drives the fixed-distance spraying unit 6 to move and spray, the clamping and positioning component 68 gradually... Near the guide plate 686 on the frame 1, the guide plate 686 exerts an inward squeezing force on the roller 685, causing the clamping block 683 to tightly clamp the fixing post 64, locking the position of the fixing post 64, thereby fixing the position of the moving plate 61, and keeping the distance between the spray nozzle 63 and the furnace roller stable. When spraying the position near the end of the furnace roller, the fixing post 62 and the third ball 621 have moved to the position of disengaging from the furnace roller. At this time, the position of the moving plate 61 is locked under the action of the clamping and positioning component 68, so that the spray nozzle 63 can still maintain the current position and continue the spraying operation.
