Description

Technical Field

[0001] The utility model relates to the technical field of steel shot production, in particular to an automatic feeding device for steel shot production. Background Art

[0002] Steel shot is a small round or oval steel ball made of high carbon steel or alloy steel. They are usually used for surface treatment in the industrial field. Steel shot is one of the commonly used media in sandblasting operations. It is used to clean and remove rust, old paint, dirt, etc. on the metal surface. Sandblasting can improve the roughness of the metal surface and enhance the adhesion of the coating. Through shot peening or shot blasting, the steel shot hits the metal surface at high speed, which can cause cold work hardening of the metal surface and improve its fatigue strength and service life. The steel shot will gradually wear and become smaller during use and eventually be replaced. The size, hardness and shape of the steel shot can be selected according to different application requirements. They are widely used in many industries such as ships, automobiles, aircraft, construction, bridges, etc. The use of steel shot can not only improve the quality and life of the product, but also improve production efficiency. It is an important industrial consumable.

[0003] The automatic feeding device for steel shot production is an automated device used in the steel shot production process, with the purpose of improving production efficiency and reducing labor costs. The main function of this type of device is to automatically feed the steel shot into the next stage of the production line, thereby reducing dependence on manual operation. The automatic feeding device for steel shot production is an important device for realizing automation and efficient production in the steel shot production process. Through such a device, not only can production efficiency and product quality be improved, but also production costs can be reduced. However, the traditional steel shot production feeding device is prone to steel ball blockage and steel ball leakage during the conveying process due to the inability to control the speed and flow rate, resulting in item loss and reduced work progress. For this reason, we propose an automatic feeding device for steel shot production to solve the above problems. Utility Model Content

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

[0013] The utility model can accurately control the flow rate of steel balls by setting the movement of the first piston and the first sliding rod, so as to avoid too many steel balls entering the receiving hopper at the same time and causing blockage or overflow. When a certain number of steel balls fall, the first piston and the first sliding rod push the baffle plate to close, so as to prevent more steel balls from entering the receiving hopper and reduce the possibility of blockage.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: an automatic feeding device for steel shot production, comprising a storage hopper 1, a group of support columns 3 are installed on the bottom surface of the storage hopper 1, a first piston 18 is installed on the outer surface of one of the support columns 3, two first sliding rods 17 are slidably connected to the inner wall of the first piston 18, and a material blocking plate 19 is commonly connected to one end of the two first sliding rods 17 close to the storage hopper 1, a second piston 15 is installed on the outer surface of one of the support columns 3, and two second sliding rods 13 are slidably connected to the inner wall of the second piston 15, wherein a connecting rod 5 is connected to a side surface of the two support columns 3 close to each other, and a receiving hopper 4 is commonly connected to a side surface of the two connecting rods 5 close to each other, a fixed frame 10 is sleeved on the outer surface of one of the support columns 3, and a cylinder 9 is connected to one end of the fixed frame 10 close to the receiving hopper 4, a telescopic rod 11 is slidably connected to the inner wall of the cylinder 9, and a partition 12 is connected to the end of the telescopic rod 11 away from the cylinder 9.

[0021] Among them, the upper surface of the storage hopper 1 is connected to an extension plate 2, and the bottom surface of the receiving hopper 4 is connected to a material transfer pipe 20. The extension plate 2 can help guide the flow of steel shots, ensuring that the steel shots can flow smoothly from the storage hopper 1 to the receiving hopper 4, reducing the possibility of material blockage and deviation.

[0022] Among them, each first sliding rod 17 is connected to a first limiting plate 16 at one end away from the storage hopper 1, and each second sliding rod 13 is connected to a second limiting plate 14 at one end away from the storage hopper 1. The first limiting plate 16 and the second limiting plate 14 can ensure that the second sliding rod 13 moves within a specific range, thereby accurately controlling the position of related components, which is very important for maintaining stable operation and repeated positioning of the device.

[0023] Among them, the end of the feeding pipe 20 away from the storage hopper 1 is connected to the fixed plate 23, and a motor 24 is installed on the right side of the fixed plate 23. The feeding pipe 20 driven by the motor 24 can accurately control the conveying speed of the steel shot to adapt to different production rhythms and needs.

[0024] Among them, the left side of the fixed plate 23 is rotatably connected to the rotating shaft 22, the output end of the motor 24 is connected to the right end of the rotating shaft 22, and the outer surface of the rotating shaft 22 is installed with a propeller 21. The design of the propeller 21 can effectively propel the material steel shots to move along the material transfer pipe 20, especially when the material needs to be transported from a low place to a high place.

[0025] Among them, the outer surface of the material transfer pipe 20 is equipped with a discharge port 25, and a material receiving box 6 is placed at the lower end of the discharge port 25. The material receiving box 6 provides a container for collecting steel shots discharged from the discharge port 25 for subsequent processing or packaging.

[0026] Among them, a group of supporting feet 8 are installed on the bottom surface of the material receiving box 6, and a discharge pipe 7 is installed on the right side of the material receiving box 6. The supporting feet 8 can ensure that the material receiving box 6 remains stable during the process of collecting steel shots, reduce the tilting or movement caused by vibration or external force, and thus improve the safety of the working environment.

[0027] Working principle: When in use, the steel balls start to fall from the storage hopper 1 and fall onto the baffle plate 19. At the same time, the first piston 18 and the first sliding rod 17 move to open the baffle plate 19. When a certain number of steel balls fall, the first piston 18 and the first sliding rod 17 push the baffle plate 19, and the second piston 15 and the second sliding rod 13 pull the baffle plate 19 to a far point to block the steel balls. The fallen steel balls fall into the receiving hopper 4, and the partition 12 on the telescopic rod 11 driven by the cylinder 9 pre-stores the steel balls for the second time. The motor 24 drives the propeller 21 to rotate and pushes the steel balls to move along the feeding pipe 20. When the transmission of the steel balls in the feeding pipe 20 is about to be completed, the telescopic rod 11 contracts, and the steel balls continue to fall. The steel balls are discharged to the receiving box 6 through the discharge port 25. The receiving box 6 collects the steel balls and flows out the steel balls through the discharge pipe 7 for easy transportation to the next production link.
