Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology, and more specifically, to a heat treatment device for rolls with continuous tempering function. Background Technology

[0002] Continuous tempering heat treatment equipment is a type of heat treatment equipment that tempers metal workpieces through continuous conveying. Its core function is to optimize the mechanical properties and service life of the workpieces by controlling temperature and time. Existing continuous tempering heat treatment equipment mainly consists of multiple heating chambers set on a chain conveyor belt. The chain conveyor belt carries the workpiece through multiple heating chambers sequentially, achieving tempering heat treatment at different temperature gradients, resulting in higher efficiency. However, when heat treating rolls, existing continuous tempering heat treatment equipment requires cleaning the rolls to prevent quality problems caused by impurities remaining on the roll surface. Current cleaning methods mainly rely on manual brushing, which is inefficient and limits the processing efficiency of the heat treatment equipment. Furthermore, for some large-volume rolls, manual brushing is insufficient to thoroughly clean the roll surface. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a roll heat treatment device with continuous tempering function to solve the problems of low efficiency and insufficient manual cleaning of rolls mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a roll heat treatment device with continuous tempering function, comprising a chain conveyor belt, wherein a plurality of heating chambers are spaced apart along the conveying direction on the chain conveyor belt, a bracket is provided at the first end of the chain conveyor belt, two corresponding rotating shafts are rotatably mounted on the bracket, each rotating shaft is drivenly connected to a rotary motor, two corresponding arc plates are fixedly mounted on each rotating shaft, a plurality of rollers are rotatably mounted between the two arc plates along their arc direction, the rollers are drivenly connected to a drive motor, a roller body cleaning brush is fixedly mounted on the arc plate between every two rollers, a spray pipe is also fixedly mounted on the bracket, and a guide slide is fixedly mounted on the bracket below the two arc plates, the end of the guide slide being aligned with the chain conveyor belt.

[0005] As a preferred embodiment of this utility model, each roller is coaxially fixed with a rubber sleeve, and the outer surface of the rubber sleeve is provided with anti-slip texture.

[0006] As a preferred embodiment of this utility model, each of the arc-shaped plates is further fixedly equipped with a roller neck cleaning brush, which is configured to correspond to the roller neck of the roll.

[0007] As a preferred technical solution of this utility model, the bottom surface of the guide slide is provided with a number of water-permeable holes, and the surface of the guide slide is covered and fixed with a cushioning pad.

[0008] As a preferred embodiment of this utility model, the surface of the guide slide is also fixedly equipped with several strip-shaped speed bumps.

[0009] As a preferred embodiment of this invention, a drying chamber is also provided on the chain conveyor belt between the guide slide and the heating chamber.

[0010] As a preferred technical solution of this utility model, a waste liquid collection tank is also provided directly below the two arc-shaped plates, and a long-stroke cylinder corresponding to the waste liquid collection tank is fixedly installed on the bracket, with the output shaft of the long-stroke cylinder connected to the waste liquid collection tank.

[0011] As a preferred embodiment of this invention, the inner wall of the waste liquid collection tank is provided with a Teflon coating.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] The system comprises curved plates, rollers, roller body cleaning brushes, and roller neck cleaning brushes. During operation, the roll to be tempered is placed between two curved plates. A drive motor is then activated to rotate the rollers on the two curved plates synchronously. The rollers, through friction, drive the roll to rotate on the two curved plates. Simultaneously, a spray pipe sprays cleaning fluid onto the roll. Combined with the roller body and neck cleaning brushes on the curved plates, the roll can be cleaned quickly. After cleaning, two rotating motors are activated, causing the curved plates and rollers to rotate outwards synchronously under the drive of the rotating shaft. The roll falls onto the guide slide below and rolls down the chain conveyor, thus quickly completing the cleaning of the roll. This results in higher processing efficiency for the continuous tempering heat treatment device and avoids quality problems caused by surface impurities on the roll during subsequent tempering processes.

[0024] 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.

[0025] like Figures 1 to 9As shown, this utility model provides a roll heat treatment device with continuous tempering function, including a chain conveyor belt 1, a plurality of heating chambers 2 are arranged at intervals along the conveying direction on the chain conveyor belt 1, a bracket 4 is provided at the first end of the chain conveyor belt 1, two corresponding rotating shafts 5 are rotatably mounted on the bracket 4, each rotating shaft 5 is driven by a rotary motor 13, two corresponding arc plates 6 are fixedly mounted on each rotating shaft 5, a plurality of rollers 7 are rotatably mounted between the two arc plates 6 along their arc direction, the rollers 7 are driven by a drive motor 8, the drive motor 8 can directly drive one roller 7, or the rollers 7 can be connected by a sprocket structure, so that one roller 7 can drive the remaining rollers 7 to rotate synchronously through the sprocket transmission, a roller body cleaning brush 9 is fixedly mounted on the arc plate 6 between every two rollers 7, a spray pipe 14 is also fixedly mounted on the bracket 4, and a guide slide 12 is fixedly mounted on the bracket 4 below the two arc plates 6, the end of the guide slide 12 is aligned with the chain conveyor belt 1. The spray pipe 14 is used to connect to the cleaning fluid supply device so that the spray pipe 14 can spray cleaning fluid onto the two arc plates 6.

[0026] Each roller 7 is coaxially fixed with a rubber sleeve, and the outer surface of the rubber sleeve is provided with anti-slip texture. The rubber layer with anti-slip texture can greatly improve the friction between the roller 7 and the roller.

[0027] Each arc plate 6 is also fixedly installed with a roller neck cleaning brush 10, which is set to correspond to the roller neck of the roll.

[0028] The bottom surface of the guide slide 12 has several water-permeable holes, and the surface of the guide slide 12 is covered with a buffer pad, which is used to reduce the impact force on the guide slide 12 when the roller falls.

[0029] Several strip-shaped deceleration belts 11 are also fixedly installed on the surface of the guide slide 12. In order to prevent the roller from gradually accelerating as it rolls down the guide slide 12, the strip-shaped deceleration belts 11 are provided. The strip-shaped deceleration belts 11 can increase the friction between the roller and the guide slide 12 itself, thereby decelerating the roller and making the end speed of the roller smaller.

[0030] A drying chamber 3 is also installed on the chain conveyor belt 1 between the guide slide 12 and the heating chamber 2.

[0031] A waste liquid collection tank 16 is also provided directly below the two arc-shaped plates 6. A long-stroke cylinder 17 corresponding to the waste liquid collection tank 16 is fixedly installed on the bracket 4. The output shaft of the long-stroke cylinder 17 is connected to the waste liquid collection tank 16, so that the long-stroke cylinder 17 can drive the waste liquid collection tank 16 to move laterally on the bracket 4. In order to prevent the waste liquid generated during cleaning from carrying impurities onto the guide slide 12 and causing the rollers to be contaminated with impurities while rolling down the guide slide 12, a waste liquid collection tank 16 is provided. The waste liquid collection tank 16 is equipped with a water outlet pipe, which is connected to a waste liquid collection device to discharge the collected waste liquid. The inner wall of the waste liquid collection tank 16 is coated with Teflon.

[0032] When using this utility model, as shown in the attached document... Figure 6 As shown, the roll to be tempered is placed between two curved plates 6. The drive motor 8 is then started, driving the rollers 7 on the two curved plates 6 to rotate synchronously. The rollers 7 drive the roll to rotate on the two curved plates 6 through friction. At this time, the spray pipe 14 sprays cleaning fluid onto the roll. The curved plates 6 are equipped with roll body cleaning brushes 9 and roll neck cleaning brushes 10, allowing for rapid cleaning of the roll. After cleaning, as shown in the attached diagram... Figure 7 As shown, two rotary motors 13 are started, synchronously driving two rotary shafts 5 to rotate, so that the arc plate 6 and the roller 7 are synchronously flipped outward under the drive of the rotary shafts 5, so that the arc plate 6 and the roller 7 will not block the roller. The roller falls onto the guide slide 12 below, rolls down the guide slide 12 onto the chain plate conveyor, and then enters the drying chamber 3 for rapid drying under the drive of the chain plate, and then passes through multiple heating chambers 2 in sequence for tempering.
