Description

Technical Field

[0001] This utility model relates to the field of conveying technology, and more specifically, to a material conveying device with positioning function. Background Technology

[0002] Heat treatment refers to a metal hot working process in which materials, in a solid state, are heated, held at temperature, and cooled to obtain the desired microstructure and properties. Cooling is an indispensable step in the heat treatment process, and the cooling methods vary depending on the process, mainly focusing on controlling the cooling rate. Generally, annealing has the slowest cooling rate, normalizing has a faster cooling rate, and quenching has an even faster cooling rate. However, different steel grades also have different requirements.

[0003] In the existing heat treatment process for round metal workpieces such as bearing rings, after the round workpiece is heated, it needs to be transported to a cooling device for surface cooling. The metal material is rapidly cooled to a certain temperature by spraying, and then cooled naturally. In this process, the workpiece is usually placed in the cooling device manually for cooling and then picked up. It is not convenient to control the spray cooling time of the workpiece, the continuity of cooling of multiple workpieces is poor, the efficiency is low, and the cooling effect between workpieces varies greatly. In view of this, we propose a material conveying device with positioning function. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a material conveying device with positioning function to solve the technical problems of the current manual placement of workpieces in cooling equipment for cooling and retrieval, which makes it inconvenient to control the time of spray cooling of workpieces and the poor cooling continuity between multiple workpieces.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a material conveying device with positioning function, including a conveyor belt passing through a cooling box, fixed frames arranged on both sides of the conveyor belt, and drive rollers drivingly connected to the symmetrical sides of the conveyor belt, with both ends of the drive rollers rotatably connected within the fixed frames, and a drive assembly arranged through the side wall of one of the drive rollers.

[0006] The transmission assembly includes a gear fixed to one end of the transmission roller. A motor is fixedly connected to one side of the fixed frame via a mounting base. A turntable is fixedly connected to the output end of the motor. Several sets of teeth are arranged in a ring at equal intervals on the surface of the turntable. Each set of teeth meshes with the gear in sequence when driven by the motor.

[0007] This invention enables intermittent conveyor belt transport under continuous motor rotation, providing dwell time for workpieces when they reach the lower end of the cooling box, ensuring effective cooling of the workpieces and equal cooling time among multiple workpieces.

[0008] Preferably, the transmission assembly further includes a limiting plate fixedly connected to the surface of the conveyor belt, the limiting plate being symmetrically distributed, and the limiting plate including a limiting part and a placement part.

[0009] Preferably, the placement part is arranged in a semi-circular arc shape between the two limiting parts, and a placement seat is placed inside the placement part.

[0010] Preferably, the placement seat has a placement cavity, and the placement cavity has different sized placement platforms that decrease in size from top to bottom in a stepped manner.

[0011] Preferably, the placement seat is provided with a flow cavity, and the side wall of the placement platform is provided with a through hole, and each placement platform is connected to the flow cavity through the through hole.

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

[0013] 1. This utility model, by setting up a transmission component, can utilize the connection between the gear and the turntable. When the turntable rotates, its multiple sets of teeth mesh with the surface of the gear and drive it to rotate synchronously. When the teeth disengage from the surface of the gear, the surface of the gear contacts the smooth surface of the turntable, limiting the position of the gear and keeping it stationary. In this way, intermittent transport of the conveyor belt can be achieved under the continuous rotation of the motor, providing a dwell time for the workpiece when it is transported to the lower end of the cooling box, ensuring the cooling effect of the workpiece and the same cooling time among multiple workpieces.

[0014] 2. This utility model also enables the positioning and calibration of the workpiece by setting a limiting part and a placement part, so that the workpiece can be placed at equal intervals and transported to the bottom of the cooling box. Furthermore, by using different sized placement platforms in the placement seat, round workpieces of different sizes can be placed. When the spray is sprayed into the placement cavity, the excess spray can flow through the through hole in the circulation cavity and be guided to the bottom of the placement cavity to contact the lower surface of the workpiece, further improving the cooling effect of rapid cooling of the workpiece surface.

[0020] like Figures 1 to 3 As shown, the present invention relates to a material conveying device with positioning function, including a conveyor belt 1 passing through a cooling box, fixed frames 3 arranged on both sides of the conveyor belt 1, and transmission rollers 2 connected to the symmetrical sides of the conveyor belt 1. The two ends of the transmission rollers 2 are rotatably connected in the fixed frames 3 at the same time, and a transmission component 4 is arranged through the side wall of one of the transmission rollers 2.

[0021] like Figure 1 and Figure 2 As shown, the transmission assembly 4 includes a gear 401 fixed to one end of the transmission roller 2. A motor 402 is fixedly connected to one side of the fixed frame 3 via a mounting base. A turntable 403 is fixedly connected to the output end of the motor 402. Several sets of teeth 404 are arranged in a ring at equal intervals on the surface of the turntable 403. Each set of teeth 404 meshes with the gear 401 sequentially when driven by the motor 402. The transmission assembly 4 also includes a limiting plate 405 fixedly connected to the surface of the conveyor belt 1. By setting the transmission assembly 4, the space between the gear 401 and the turntable 403 can be utilized. When the turntable 403 rotates, its multiple sets of teeth 404 mesh with the surface of the gear 401 and drive it to rotate synchronously. When the teeth 404 disengage from the surface of the gear 401, the surface of the gear 401 contacts the smooth surface of the turntable 403, limiting the position of the gear 401 and keeping it stationary. In this way, under the continuous rotation of the motor 402, the conveyor belt 1 can realize intermittent transportation, providing a dwell time for the workpiece when it is transported to the lower end of the cooling box, ensuring the cooling effect of the workpiece and the same cooling time among multiple workpieces.

[0022] In the embodiment of the present utility model, as Figure 2 and Figure 3As shown, the limiting plates 405 are symmetrically distributed. Each limiting plate 405 includes a limiting part 4051 and a placement part 4052. The placement part 4052 is arranged in a semi-circular arc shape between the two limiting parts 4051. A placement seat 5 is placed inside the placement part 4052. A placement cavity 6 is formed inside the placement cavity 6. The placement cavity 6 forms placement platforms 61 of different sizes that decrease in size from top to bottom in a stepped manner. A flow cavity 7 is also formed inside the placement seat 5. The side wall of the placement platform 61 is formed with a through hole. Each placement platform 61 is connected to the flow cavity 7 through the through hole. By setting the limiting part 4051 and the placement part 4052, the placement position of the workpiece can be positioned and calibrated, so that the workpiece can be placed at equal intervals and transported to the bottom of the cooling box. Furthermore, by using the different sized placement platforms 61 in the placement seat 5, round workpieces of different sizes can be placed. When the spray is sprayed into the placement cavity 6, the excess spray can flow through the through hole in the flow cavity 7 and be guided to the bottom of the placement cavity 6 to contact the lower surface of the workpiece, further improving the cooling effect of rapid cooling of the workpiece surface.

[0023] Working Principle: This embodiment provides a material conveying device with positioning function. In use, the heated workpiece is first placed manually into the placement seat 5 using auxiliary tools. Different sized workpieces are placed using the stepped placement platform 61, and the placement seat 5 is positioned according to the placement part 4052. Then, the motor 402 drives the turntable 403 and gear 404 to rotate. During rotation, each set of gears 404 meshes with the gear 401, thereby driving the gear 401 forward. The conveyor belt 1 rotates, enabling it to transport the placement seats 5. In the gap between each set of teeth 404, the surface of the turntable 403 contacts and adheres to the surface of the gear 401, thus keeping the gear 401 stationary. This provides equal dwell time after multiple sets of placement seats 5 are transported into the cooling box, ensuring the cooling time and effect of each workpiece. When spraying the workpiece for cooling, the connection between the flow cavity 7 and the through hole allows the spray to circulate on the inner wall of the placement seat 5, further improving the cooling effect on the workpiece surface.

[0024] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
