Description

Technical Field

[0001] This utility model relates to the field of mesh belt idler furnaces, specifically a continuous mesh belt idler furnace production line. Background Technology

[0002] A mesh belt idler furnace is a continuous heat treatment equipment that combines mesh belt conveying with idler support. It is mainly used for heat treatment processes of metal materials, such as quenching, tempering, and solution treatment. The mesh belt drive system consists of a high-temperature resistant mesh belt and a transmission device. The mesh belt runs smoothly, and the speed can be adjusted steplessly by a frequency converter.

[0003] Mesh belt roller furnaces utilize mesh belts for material transport and heat treatment in a high-temperature environment. Workpieces are placed on the mesh belt, and through the rotation of the rollers and the movement of the mesh belt, the workpieces continuously advance within the furnace, undergoing stages such as heating, heat preservation, and cooling to complete the heat treatment process.

[0004] In existing mesh belt idler furnaces, a large number of workpieces are usually directly fed onto the mesh belt for heat treatment. However, during use and observation, it has been found that this conveying method can easily lead to the accumulation of workpieces, which affects the heating and cooling process and thus the quality of heat treatment.

[0005] Therefore, a continuous mesh belt idler roller furnace production line is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The continuous mesh belt idler furnace production line of this utility model includes a normalizing section, a cooling section, and a tempering section. Each of the normalizing section, cooling section, and tempering section includes a mesh belt conveyor. Thermocouples and heating components are provided inside the normalizing section and the tempering section. A pair of vertical plates are fixedly installed on one side of the normalizing section. A hopper is fixedly connected between the pair of vertical plates. A pair of sliding plates are provided on the inner wall of the hopper, and the sliding plates are inclined. Through the cooperation of the hopper and the sliding plates, the output flow of the workpiece can be restricted by the sliding plates, thereby improving the uniformity of the workpiece distribution on the conveyor, enhancing the subsequent heating effect, and reducing the accumulation of workpieces.

[0008] Preferably, an adjusting motor is fixedly connected to the middle of one side of the upright plate; a gear is fixedly connected to the output end of the adjusting motor; the gear and the outer wall of the hopper are rotatably connected; a rack is slidably connected to the outer wall of the hopper; the rack and the gear are meshed; limit plates are symmetrically fixedly connected to both sides of the rack; the slide plate and the hopper are slidably connected; a fixing pin is fixedly connected to the outer wall of the slide plate; the fixing pin and the limit plate are slidably connected; by setting the limit plate and the fixing pin, starting the adjusting motor can drive the slide plate to slide along the hopper through the meshing of the gear and rack, thereby limiting the flow of workpieces of different sizes and improving the adaptability and flexibility of the slide plate for limiting the flow of workpieces of various sizes.

[0009] Preferably, multiple guide strips are symmetrically fixed to the inner wall of the hopper; the guide strips are equidistant; by setting the guide strips, the workpiece will flow along the inner wall of the hopper after being added into the hopper. At this time, the guide strips can provide additional guidance for the workpiece, thereby improving the orderliness of the workpiece flow and facilitating subsequent flow restriction and heating of the workpiece.

[0010] Preferably, a guide plate is fixed to the inner wall of the hopper; the end face of the guide plate is inclined; by setting the guide plate, because the end face of the guide plate is inclined, the workpiece can be forced to flow to the inner wall of the hopper under the guidance of the guide plate after being added into the hopper and guided by the guide strip, which further improves the uniformity of the workpiece flow in the hopper and reduces the local accumulation.

[0011] Preferably, the cooling section further includes an air duct; the bottom of the air duct is flared; by setting the air duct, the end of the air duct can be connected to a cold air supply device, so that the cooling airflow can pass through the air duct to exchange heat and cool the workpiece on the mesh belt in the cooling section. By setting the bottom of the air duct to be flared, the airflow range can be increased, thereby increasing the contact area between the airflow and the workpiece.

[0012] Preferably, a grille is fixed to the bottom of the air duct; by setting the grille, the output airflow in the air duct can be evenly distributed, so that the airflow can cover the surface of the workpiece more evenly. At the same time, the grille can also prevent large impurities from entering the interior of the air duct and protect the cleanliness of the air duct.

[0013] The advantages of this utility model are: 1. The continuous mesh belt idler furnace production line of this utility model, through the cooperation of the hopper and the sliding plate, allows the workpiece to be restricted by the sliding plate to improve the uniformity of the workpiece distribution on the conveyor, thereby enhancing the subsequent heating effect and reducing the accumulation of workpieces.

[0014] 2. The continuous mesh belt idler furnace production line of this utility model, by setting a limiting plate and fixing pin, can drive the slide plate to slide along the hopper through gear and rack meshing when the adjusting motor is started, thereby limiting the flow of workpieces of different sizes and improving the adaptability and flexibility of the slide plate to limiting the flow of workpieces of various sizes.

[0018] 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 scope of protection of the present utility model.

[0019] Specific implementation examples are given below.

[0020] Please see Figures 1 to 6As shown in the embodiment of this utility model, a continuous mesh belt idler furnace production line includes a normalizing section 1, a cooling section 12, and a tempering section 13. Each of the normalizing section 1, cooling section 12, and tempering section 13 includes a mesh belt conveyor. Thermocouples and heating components are installed inside both the normalizing section 1 and the tempering section 13. A pair of vertical plates 14 are fixedly installed on one side of the normalizing section 1. A hopper 15 is fixedly connected between the pair of vertical plates 14. A pair of sliding plates 16 are provided on the inner wall of the hopper 15, and the sliding plates 16 are inclined. During operation, workpieces can be added in batches through the hopper 15. The workpieces pass through the pair of sliding plates 16 and are discharged through the gap between the sliding plates 16, allowing the workpieces to be flow-limited by the sliding plates 16 and input to the mesh belt conveyor in the normalizing section 1. The power source of the mesh belt conveyor can be a motor. The mesh belt is sleeved on the idler rollers, and the idler rollers are provided with positioning plates to limit the mesh belt movement and prevent it from shifting. To prevent misalignment, the idlers are driven by sprockets and chains. The workpiece is conveyed to the normalizing section 1 by the conveyor and heated by the heating components inside the normalizing section 1. The heating components can be electric heating, which is a mature existing technology and will not be described in detail here. During the heating process, hot air can be introduced through a fan connected to the top of the normalizing section 1 to expand the heating area. The heated workpiece can be conveyed to the cooling section 12 and cooled by the cooling section 12. The cooled workpiece can then be conveyed to the tempering section 13. The internal structure of the tempering section 13 can be the same as that of the normalizing section 1 to continue heating the workpiece until it is output from the tempering section 13. Finally, the workpiece can be naturally cooled to complete the heat treatment. Through the cooperation of the hopper 15 and the slide plate 16, the output flow of the workpiece can be restricted by the slide plate 16, thereby improving the uniformity of the workpiece distribution on the conveyor, enhancing the subsequent heating effect, and reducing the accumulation of workpieces.

[0021] Please see Figure 4 and Figure 5As shown, an adjusting motor 2 is fixedly connected to the middle of one side of the upright plate 14; a gear 22 is fixedly connected to the output end of the adjusting motor 2; the gear 22 and the outer wall of the hopper 15 are rotatably connected; a rack 23 is slidably connected to the outer wall of the hopper 15; the rack 23 and the gear 22 are meshed; limit plates 24 are symmetrically fixed to both sides of the rack 23; the slide plate 16 and the hopper 15 are slidably connected; a fixing pin 25 is fixedly connected to the outer wall of the slide plate 16; the fixing pin 25 and the limit plate 24 are slidably connected; when processing different batches of workpieces, i.e., when there are differences in workpiece size, the adjusting motor 2 can be started to drive the gear 22 to rotate, and the gear 22 will mesh with the rack 23. When the rack 23 engages, it moves vertically along the hopper 15. The rack 23 moves along with the limiting plate 24. When the limiting plate 24 moves vertically, it can control the slide plate 16 to slide obliquely along the hopper 15 by applying corresponding upward and downward pressure to the fixing pin 25. This controls the opening size between a pair of slide plates 16, thus adapting to flow restriction of workpieces of different sizes. By setting the limiting plate 24 and the fixing pin 25, starting the adjusting motor 2 can drive the slide plate 16 to slide along the hopper 15 through the engagement of the gear 22 and the rack 23. This allows for flow restriction of workpieces of different sizes, improving the adaptability and flexibility of the slide plate 16 in flow restriction of workpieces of various sizes.

[0022] Please see Figure 5 As shown, multiple guide strips 3 are symmetrically fixed to the inner wall of the hopper 15; the guide strips 3 are equidistantly arranged; by setting the guide strips 3, after the workpiece is added into the hopper 15, it will flow along the inner wall of the hopper 15. At this time, the guide strips 3 can provide additional guidance for the workpiece, thereby improving the orderliness of the workpiece flow and facilitating the subsequent flow restriction output and heating of the workpiece.

[0023] Please see Figure 5 As shown, a guide plate 4 is fixedly connected to the inner wall of the hopper 15; the end face of the guide plate 4 is inclined; by setting the guide plate 4, because the end face of the guide plate 4 is inclined, the workpiece can be forced to flow to the inner wall of the hopper 15 under the guidance of the guide plate 4 after being added into the hopper 15 and guided by the guide strip 3, which further improves the uniformity of the workpiece flow in the hopper 15 and reduces the local accumulation.

[0024] Please see Figure 6 As shown, the cooling section 12 also includes an air duct 5; the bottom of the air duct 5 is flared; by setting the air duct 5, the end of the air duct 5 can be connected to a cold air supply device, so that the cooling airflow can be passed through the air duct 5 to exchange heat and cool the workpiece on the mesh belt at the cooling section 12. By setting the bottom of the air duct 5 to be flared, the airflow range can be increased, thereby increasing the contact area between the airflow and the workpiece.

[0025] Please see Figure 6As shown, a grille 6 is fixedly connected to the bottom of the air duct 5; by setting the grille 6, the grille 6 can evenly distribute the output airflow in the air duct 5, so that the airflow can more evenly cover the surface of the workpiece. At the same time, the grille 6 can also prevent large impurities from entering the interior of the air duct 5, thus protecting the cleanliness of the air duct 5.

[0026] Working principle: Workpieces are added in batches through hopper 15. Within hopper 15, the workpieces pass through a pair of sliding plates 16 and are discharged through the gap between the plates. This allows the workpieces to be flow-limited by the sliding plates 16 and input to the mesh belt conveyor in normalizing section 1. The mesh belt conveyor can be powered by an electric motor. The mesh belt is fitted onto idler rollers, and the idler rollers are equipped with positioning plates to limit the mesh belt and prevent it from deviating. The idler rollers are driven by sprockets and chains. The workpieces are conveyed to the normalizing section 1 and heated by the heating components within the normalizing section 1. The heating components can be electrically heated, which is a mature existing technology and will not be described in detail here. During the heating process, a fan can be connected to the top of normalizing section 1. Hot air is introduced to expand the heating area. The heated workpiece can be conveyed to the cooling section 12 and cooled there. The cooled workpiece can then be conveyed to the tempering section 13, whose internal structure can be the same as the normalizing section 1, to continue heating the workpiece until it is output from the tempering section 13. Finally, the workpiece can be naturally cooled to complete the heat treatment. When processing different batches of workpieces, i.e., when there are differences in workpiece size, the gear 22 can be driven to rotate by starting the regulating motor 2. The gear 22 will mesh with the rack 23, causing the rack 23 to move vertically along the hopper 15. The rack 23 will also move along with the limiting plate 24. When the limiting plate 24 moves vertically, it can control the sliding plate 16 to slide obliquely along the hopper 15 by applying corresponding upward and downward pressure to the fixing pin 25, thereby controlling the opening size between a pair of sliding plates 16 to adapt to the flow restriction work of workpieces of different sizes; by setting the guide strip 3, after the workpiece is put into the hopper 15, it will flow along the inner wall of the hopper 15. At this time, the guide strip 3 can provide additional guidance for the workpiece, thereby improving the orderliness of the workpiece flow and facilitating the subsequent flow restriction output and heating of the workpiece; by setting the guide plate 4, because the end face of the guide plate 4 is inclined, the workpiece can be forced to flow under the guidance of the guide plate 4 after being put into the hopper 15. The inner wall of the hopper 15 is guided by the guide strip 3, which further improves the uniformity of the workpiece flow in the hopper 15 and reduces local accumulation. By setting the air duct 5, the end of the air duct 5 can be connected to the cold air supply equipment, so that the cooling airflow can be passed through the air duct 5 to exchange heat and cool the workpiece on the mesh belt at the cooling section 12. By setting the bottom of the air duct 5 to be flared, the airflow range can be increased, thereby increasing the contact area between the airflow and the workpiece. By setting the grid 6, the grid 6 can evenly distribute the output airflow in the air duct 5, so that the airflow can more evenly cover the surface of the workpiece. At the same time, the grid 6 can also prevent large impurities from entering the interior of the air duct 5, protecting the cleanliness of the air duct 5.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
