Description

Technical Field

[0001] This utility model relates to the field of chain conveyor technology, and in particular to a cooling device for a conveyor chain. Background Technology

[0002] A conveyor chain is a mechanical device specifically designed for conveying and simultaneously cooling steel strips. It typically consists of a conveyor belt, drive unit, cooling system, support structure, and control system.

[0003] During operation, the drive unit moves the strip steel, transporting it from one location to another. The cooling system then cools the strip steel during transport to meet the requirements of the production process. This type of equipment is commonly found in industries such as metal processing, chemicals, and food. For example, on continuous production lines for thin metal sheets, the strip steel, after heat treatment, needs to be rapidly cooled via a cooling conveyor to achieve the specified properties and shape.

[0004] Currently, during the strip rolling process, due to insufficient flatness, excessively narrow width, or uneven thickness, strip may warp, affecting the winding operation of the coiling device. Furthermore, the conveyor chain may deviate during the conveying of the strip. The strip is generally guided by a fixed guiding device, which cannot adjust the strip as a whole on the conveyor chain, causing the strip to always follow the guide blocks on the guiding device. This results in small extrusion deformation on one side of the strip.

[0005] To address the problems in the prior art, a conveyor chain plate cooling device is provided. Utility Model Content

[0006] In view of this, the present invention proposes a conveyor chain plate cooling device to solve the problems of strip lifting and strip offset on one side.

[0011] Furthermore, preferably, the lifting frame is slidably fitted on both sides within the first and second lifting slots provided on both sides of the movable plate frame.

[0012] Furthermore, preferably, the guiding device includes a square frame plate, which is fixedly connected to the middle of the upper surface of the movable plate frame by bolts. An electric push rod is fixedly connected inside the square frame plate. The output end of the electric push rod is connected to a telescopic rod.

The first pushing assembly includes a first rotating frame, which is fixedly connected to one side of the pressure plate. A transmission plate is rotatably connected to the rotating frame through a first fixed rod. A second rotating frame is rotatably connected to one side of the transmission plate through a second fixed rod. A push rod is fixedly connected to the lower end of the second rotating frame.

Detailed Implementation

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0027] like Figure 1 As shown, combined with Figure 2-5 This utility model discloses a conveyor chain plate cooling device, including a support frame 1, a protective shell 11 on the upper surface of the support frame 1, a conveying device 12 inside the protective shell 11, and a strip steel 13 placed on the upper surface of the conveyor chain plate on the conveying device 12; a spray assembly 2 is provided on one side of the upper surface of the protective shell 11; a moving assembly 3 is provided on the other side of the protective shell 11, and a straightening assembly 4 and a guiding device 5 are provided inside the moving assembly 3.

[0028] In this embodiment, the spray assembly 2 includes two support plates 21 fixedly connected to the upper surface of one side of the protective shell 11. A water pump box 22 is fixedly connected to the upper surface of the two support plates 21. A water inlet pipe 23 is connected to one side of the water pump box 22, and spray elements 24 are arranged equidistantly along the length direction on the lower surface of the water pump box 22. The lower surface of the spray elements 24 is directly opposite the upper surface of the conveyor chain plate. When the water pump box 22 on the spray assembly 2 is started, water is delivered into the spray elements 24. The atomization of the spray elements 24 cools the strip steel 13 and also reduces the temperature of the conveyor chain plate and sprocket. This effectively avoids the loss of lubricating grease due to high temperature, improves the service life of the conveyor chain plate, and reduces equipment accidents.

[0029] In this embodiment, the movable component 3 includes a movable plate frame 31. Sliding plates 32 are fixedly connected to the lower part of both inner side walls of the movable plate frame 31. The sliding plates 32 are slidably engaged with sliding grooves 33 opened on both sides of the protective shell 11. A fixed plate 34 is fixedly connected to the lower part of one side of the movable plate frame 31. A first motor 35 is connected to one side of the fixed plate 34. A rotating shaft 36 is connected to the output end of the first motor 35. A gear 37 is sleeved on the lower end of the rotating shaft 36. The gear 37 meshes with a rack 38. A supporting long plate 39 is fixedly connected to the rack 38. One side of the supporting long plate 39 is fixedly connected to one side of the protective shell 11. The first motor 35 is started to drive the rotating shaft 36 to rotate counterclockwise. The rotating shaft 36 is driven counterclockwise to drive the gear 37. The gear 37 is driven counterclockwise to mesh with the rack 38, causing the moving plate frame 31 to slide in the two sliding grooves 33 through the two sliding plates 32 towards one side of the strip steel 13. After the moving plate frame 31 moves to the upper end face of one side of the strip steel 13, the first motor 35 is stopped and the second motor 42 is started, so that the roller 48 presses against the upper end face of the strip steel 13. The second motor 42 is stopped and the first motor 35 is started, so that the roller 48 rolls to one side to press against the upper end face of the strip steel 13. After the pressure roller 48 presses against one side of the strip steel 13, the second motor 42 is started to make the pressure roller 48 retract upward. Then, the above steps are repeated to press against the side of the strip steel 13 that is raised. This is beneficial to realize the reciprocating operation of the pressing work and can also realize the movement length of the overall guide strip steel 13.

[0030] In this embodiment, the straightening assembly 4 includes a fixed housing 41. The lower end face of the fixed housing 41 is fixed to the upper end face of the movable plate frame 31, and a second motor 42 is fixedly connected inside the fixed housing 41. The output end of the second motor 42 is connected to a screw 43. The upper end of the screw 43 is inserted into a first through hole opened on the upper end face of the movable plate frame 31, and the lower end of the screw 43 is engaged in a spiral groove opened in the middle of the lifting frame 44. A first connecting plate 45 and a second connecting plate 46 are fixedly connected to both sides of the lifting frame 44. A pressure rod 47 is fixedly connected to the lower part of the opposite surface of the first connecting plate 45 and the second connecting plate 46. A pressure roller 48 is sleeved on the outside of the pressure rod 47, and the lower part of the outer side of the pressure roller 48 presses against the upper end face of the strip steel 13. The second motor 42 is started to drive the screw 43 to rotate clockwise. The screw 43 is forcefully engaged clockwise in the spiral groove, causing the two sides of the lifting frame 44 to slide downwards into the first lifting groove 49 and the second lifting groove 491. At the same time, the first connecting plate 45, the second connecting plate 46, the pressure rod, and the pressure roller 48 are driven to move downwards. The pressure roller 48 is forcefully pressed downwards against one side of the strip 13. At this time, the second motor 35 is stopped, and the first motor 42 is started to move the moving plate frame 31 in the opposite direction. The outer side of the pressure roller 48 is driven to roll and press against one side of the strip 13, pressing against the side of the strip 13 that is raised. This facilitates the reciprocating rolling and pressing of the raised side of the strip 13, effectively preventing the winding operation of the winding device from being affected later, thereby improving the pressing effect.

[0031] In this embodiment, the lifting frame 44 is slidably fitted on both sides within the first lifting groove 49 and the second lifting groove 491 formed on both sides of the movable plate frame 31. This facilitates the stable up-and-down operation of the roller 48.

[0032] In this embodiment, the guiding device 5 includes a square frame plate 51, which is fixedly connected to the middle of the upper surface of the movable plate frame 31 by bolts. An electric push rod 52 is fixedly connected inside the square frame plate 51. The output end of the electric push rod 52 is connected to a telescopic rod 53. A pressure plate 54 is fixedly connected to the lower end of the telescopic rod 53. A first pushing assembly 55 and a second pushing assembly 56 are provided on both sides of the pressure plate 54. The first pushing assembly 55 includes a first rotating frame 551, which is fixedly connected to one side of the pressure plate 54 and is connected to a first fixing rod. A transmission plate 552 is rotatably connected. A second rotating frame 553 is rotatably connected to one side of the transmission plate 552 via a second fixed rod. A push rod 554 is fixedly connected to the lower end face of the second rotating frame 553. A push plate 555 is fixedly connected to one end face of the push rod 554, and one end of the push rod 554 is slidably fitted into a first sliding hole 556 located on the lower side of the movable plate frame 31. A limit plate 5541 is connected to one end face of the push rod 554. A spring body 557 is connected between one side of the limit plate 5541 and one side of the movable plate frame 31. One side of the push plate 555 abuts against one side of the strip steel 13. The sliding rod 558 slides downwards inside the second sliding hole 559. The first motor 35 is started, causing the movable plate frame 31 to move towards the spray assembly 2. After it approaches the spray assembly 2, the first motor 35 is stopped, and the electric push rod 52 is started to drive the telescopic rod 53 to move downward. The telescopic rod 53 is forced downward, driving the pressure plate 54. As the pressure plate 54 moves downward, the sliding rod 558 slides downward inside the second sliding hole 559. The pressure plate 54, through the first rotating frame 551 and the first fixed rod, presses down on the transmission plate 552. The transmission plate 552, through the force of the second fixed rod, moves downward... The push rod 554 slides to one side through the first sliding hole 556 and is pressed to one side by the limiting plate 5541 against the spring body 557. The push rod 554 drives the push plate 555 to one side, which in turn presses against one side of the strip 13. Simultaneously, the push plate 555 on the second pushing assembly 56 also presses against the other side of the strip 13 until the strip 13 is pushed to the middle of the conveyor chain by the two push plates 555, at which point the electric push rod 52 stops. Then, the first motor 35 is started, causing the moving plate frame 31 to move the two push plates 555 to one side. The two push plates 555 press against the side of the offset strip 13, guiding the strip 13 on the conveyor chain and concentrating it at the middle of the upper surface of the conveyor chain. The moving plate frame 31 then reaches the middle of the conveyor chain. Figure 1As shown. By setting two push plates 555, the distance between the two push plates 555 is greater than the width of the strip 13, avoiding excessive pressure and preventing the two push plates 555 from getting stuck during movement. The two push plates 555 and the movable frame plate 31 are used to guide the strip 13 located on the conveyor chain plate as a whole, eliminating the need for continuous guidance. This solves the problem of fixed guiding devices constantly guiding the strip, and avoids the problem of small compression deformation on one side of the strip 13, effectively improving practicality and work performance.

[0033] In this embodiment, a sliding rod 558 is fixedly connected to one side of the pressure plate 54. The sliding rod 558 is slidably fitted into a second sliding hole 559 opened on one side of the upper end face of the movable plate frame 31. The first pushing component 55 and the second pushing component 56 have the same structural position. By sliding the sliding rod 558 downward inside the second sliding hole 559, the pressure plate 54 is ensured to move stably up and down.

[0034] The working principle of this utility model is as follows:

[0035] In this invention, firstly, after the strip steel 13 undergoes the rolling process, one side of the strip steel 13 exits from the vibrating outlet and moves onto the conveyor chain plate on the conveying device 12. Then, the water pump box 22 on the spray assembly 2 is started to deliver water into the spray element 24. The atomization of the spray element 24 cools the strip steel 13 and also reduces the temperature of the conveyor chain plate and sprocket. After one side of the strip steel 13 is cooled, it continues to move to one side via the conveyor chain plate. If one side of the strip steel 13 tilts, the first motor 35 can be started to drive the rotating shaft 36 to rotate counterclockwise (the original state of the moving plate frame 31). Figure 1As shown), the rotating shaft 36 is driven counterclockwise to drive the gear 37. The gear 37 is driven counterclockwise to mesh with the rack 38, causing the moving plate frame 31 to slide towards the strip steel 13 through the two sliding plates 32 into the two sliding grooves 33. After the moving plate frame 31 moves to the upper end face of the strip steel 13, the first motor 35 is stopped and the second motor 42 is started to drive the screw 43 to rotate clockwise. The screw 43 is driven clockwise to mesh with the spiral groove, causing the two sides of the lifting frame 44 to slide downward into the first lifting groove 49 and the second lifting groove 491. At the same time, the first connecting plate 45 and the second connecting plate 491 are driven. Plate 46, pressure bar, and pressure roller 48 move downwards. The pressure roller 48 is pressed downwards against one side of the strip 13. At this time, the second motor 35 is stopped, and the first motor 42 is started to move the moving plate frame 31 in the opposite direction. The outer side of the pressure roller 48 rolls and presses against one side of the strip 13, pressing against the side of the strip 13 that is raised. After the pressure roller 48 presses against one side of the strip 13, the second motor 42 is started to retract the pressure roller 48 upwards. Then, the above steps are repeated to press against the side of the strip 13 that is raised. After the side of the strip 13 that is raised is parallel, this work is stopped.

[0036] When a misalignment occurs in the conveyor belt 13, the first motor 35 can be activated to move the movable plate frame 31 towards the spray assembly 2. After it approaches the spray assembly 2, the first motor 35 is stopped, and the electric push rod 52 is activated to drive the telescopic rod 53 to move downward. The telescopic rod 53 is forced downward, driving the pressure plate 54. As the pressure plate 54 moves downward, the sliding rod 558 slides downward inside the second sliding hole 559. The pressure plate 54, through the first rotating frame 551 and the first fixed rod, presses down on the transmission plate 552. The transmission plate 552, through the force of the second fixed rod, presses down against the second fixed rod. On the second rotating frame 553, the push rod 554 slides to one side in the first sliding hole 556, and is pressed to one side by the limiting plate 5541 against the spring body 557. The push rod 554 drives the push plate 555 to one side, and the push plate 555 presses against one side of the strip 13. Simultaneously, the push plate 555 on the second pushing assembly 56 also presses against the other side of the strip 13 until the strip 13 is pushed to the middle of the conveyor chain by the two push plates 555. The electric push rod 52 stops. The distance between the two push plates 555 is greater than the width of the strip 13. Then, the first motor 35 is started, causing the moving plate frame 31 to move the two push plates 555 to one side. The two push plates 555 press against the side of the offset strip 13, guiding the strip 13 on the conveyor chain to move as a whole and concentrating it at the middle of the upper surface of the conveyor chain. The moving plate frame 31 reaches the middle of the upper surface of the conveyor chain. Figure 1 As shown, stop the first motor 35, start the electric push rod 52 to drive the two push plates back to their original positions. If the deviation occurs again, continue the above steps to move and guide them.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
