Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy screw material mixing technology, and in particular to a powder metallurgy screw material mixing device with a protective mechanism. Background Technology

[0002] The screw conveyor for powder metallurgy is a mixing device specifically designed for powder metallurgy processes. It is primarily used for the efficient and uniform mixing of powder metallurgy raw materials to promote mixing and reaction between materials, thereby improving product quality and production efficiency. This device is widely used in the powder metallurgy industry and is an indispensable piece of equipment in the production process.

[0003] Existing mixing devices generate a large amount of dust during the mixing of powdered materials. This dust pollution leads to a decline in air quality in the working environment. Prolonged exposure to dust pollution can not only damage the respiratory system of employees but also cause other health problems such as skin diseases and eye discomfort. Utility Model Content

[0004] The purpose of this invention is to provide a powder metallurgy screw material mixing device with a protective mechanism. This device prevents materials from flying and spreading during the mixing process, thus solving the problem of materials easily flying and spreading during the mixing process in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A powder metallurgy screw material mixing device with a protective mechanism includes a housing. A vertical rod is rotatably connected inside the housing. Multiple horizontal rods are arranged in a circular array on the sidewall of the vertical rod. A cylindrical column is rotatably connected inside the housing, with the vertical rod and cylindrical column rotatably connected through it. Multiple rods are arranged in a circular array on the sidewall of the cylindrical column. A lever plate is fixedly connected to both sides of the cylindrical column, with its lower end fitting against the bottom of the housing and located below the rods. A discharge pipe is fixedly connected through it to the lower end of the housing. An upper cover is located on the upper end of the housing. A feed cylinder is located on the upper end of the upper cover. A turntable is rotatably connected inside the upper cover. Multiple storage troughs are arranged in a circular array on the upper end of the turntable, and multiple slots are arranged in a circular array on the lower end of the turntable. The slots communicate with the storage troughs, and a lower cover is rotatably connected inside the slots. A discharge port is located at the lower end of the upper cover.

[0007] Preferably, a drive motor is fixedly connected to the lower end of the housing, a main gear is rotatably connected inside the lower end of the housing, the output end of the drive motor is fixedly connected to the lower end of the main gear, and the upper end of the main gear is fixedly connected to the lower end of the vertical rod.

[0008] Preferably, a transmission gear is rotatably connected inside the lower end of the housing, and the transmission gear meshes with the main gear.

[0009] Preferably, a gear is rotatably connected inside the lower end of the housing, the gear is fixedly connected to the cylinder, and a belt is provided on the outside of the gear and the outside of the transmission gear.

[0010] Preferably, a motor is fixedly connected to the upper end of the cover, and a gear is fixedly connected to the output end of the motor.

[0011] Preferably, the upper end of the turntable is provided with a groove, and a plurality of tooth blocks are arranged in a ring array on the inner wall of the groove, and the gear two meshes with the tooth blocks.

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

[0013] 1. The motor drives gear two to rotate, which in turn pushes a toothed block, which in turn drives a turntable to rotate. As the turntable rotates, one of the storage troughs moves below the feed cylinder, allowing material inside the feed cylinder to fall into the storage trough. Simultaneously, the material is positioned above the lower cover. The turntable then rotates again, blocking the feed cylinder outlet at the upper part of the turntable where no storage trough is located. The storage trough containing material then rotates above the outlet. At this point, due to gravity, the lower cover rotates downwards, and a portion of the lower cover slides towards the outlet. Inside the feed inlet, the trough is opened, and the material inside the storage tank falls into the housing through the trough and the discharge port. The turntable continues to rotate, and the lower cover, located inside the discharge port, contacts the side wall of the discharge port. As the turntable rotates, the lower cover rotates into the trough, sealing the storage tank. At the same time, the turntable rotates, and the part of the lower end of the turntable without a trough seals the discharge port. By rotating the turntable, the feed cylinder and the discharge port are sealed, preventing the material from flying and spreading during the mixing process, thereby improving the overall protection of the device.

[0014] 2. The drive motor drives the main gear to rotate, which in turn drives the vertical rod to rotate in the forward direction. The vertical rod drives multiple horizontal rods on the side wall to rotate in the forward direction, and the transmission gear rotates accordingly. Through a belt, the kinetic energy of the transmission gear is transmitted to gear one, causing gear one to drive the cylinder to rotate in the reverse direction. The cylinder drives two rods and two levers on the side wall to rotate in the reverse direction. Through the agitation in both directions, the material inside the shell is fully mixed, preventing blockage or quality problems caused by material agglomeration during subsequent processing. This improves the mixing efficiency of powder materials. At the same time, thorough mixing reduces the impact and wear of materials on the mixing equipment, extending the service life of the equipment. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5A powder metallurgy screw material mixing device with a protective mechanism includes a housing 001. A vertical rod 106 is rotatably connected inside the housing 001. Multiple horizontal rods 107 are arranged in a ring array on the side wall of the vertical rod 106. A cylindrical column 108 is rotatably connected inside the housing 001. The vertical rod 106 and the cylindrical column 108 are rotatably connected through each other. Multiple rods 109 are arranged in a ring array on the side wall of the cylindrical column 108. A lever plate 110 is fixedly connected to both sides of the cylindrical column 108. The lower end of the lever plate 110 is attached to the bottom of the inner part of the housing 001. The lever plate 110 is located below the rods 109. A discharge pipe 111 is fixedly connected through the lower end of the housing 001.Upper cover 002 is located on the upper part of housing 001. A feed cylinder 201 is located on the upper part of upper cover 002. A turntable 204 is rotatably connected inside upper cover 002. Multiple storage troughs 207 are arranged in a circular array on the upper part of turntable 204, and multiple slots 208 are arranged in a circular array on the lower part of turntable 204. Slots 208 communicate with storage troughs 207. A lower cover 209 is rotatably connected inside slots 208. A discharge port 210 is located at the lower end of upper cover 002. The lower cover 209 rotates into the slots 208, sealing the inside of storage troughs 207. The upper and lower ends of turntable 204 are respectively connected to upper cover 001. 02 The two ends of the internal structure are fitted together. A valve is installed inside the discharge pipe 111. The discharge port 210 is offset from the feed cylinder 201. The operator feeds the powder metallurgy screw material into the feed cylinder 201. The turntable 204 rotates, rotating one of the storage tanks 207 to below the feed cylinder 201. The material inside the feed cylinder 201 falls into the storage tank 207, and the material is located above the lower cover 209. Then the turntable 204 rotates. At this time, the part of the turntable 204 without the storage tank 207 is blocked at the outlet end of the feed cylinder 201, and the storage tank 207 containing the material is rotated to the discharge port 210. Above 10, under the influence of gravity, the lower cover 209 rotates downwards, and a portion of the lower cover 209 slides into the discharge port 210, opening the slot 208. The material inside the storage tank 207 falls into the housing 001 through the slot 208 and the discharge port 210. The turntable 204 continues to rotate, and a portion of the lower cover 209 inside the discharge port 210 contacts the side of the discharge port 210. As the turntable 204 rotates, the lower cover 209 rotates into the slot 208, sealing the storage tank 207. Through the above steps, the material inside the feed cylinder 201 is conveyed to the housing 001. Inside the shell 001, after the material is introduced, the vertical rod 106 drives multiple horizontal rods 107 on the side wall to rotate in the forward direction. Simultaneously, the cylinder 108 drives two rods 109 and two levers 110 on the side wall to rotate in the opposite direction. This two-way agitation ensures thorough mixing of the material inside the shell 001. After thorough mixing, the valve inside the discharge pipe 111 opens, allowing the material to be discharged through the discharge pipe 111 to the outside of the shell 001. At the same time, the levers 110 push the material above the discharge pipe 111 to prevent excessive material residue inside the shell 001.

[0023] A drive motor 101 is fixedly connected to the lower end of the housing 001. A main gear 102 is rotatably connected inside the lower end of the housing 001. The output end of the drive motor 101 is fixedly connected to the lower end of the main gear 102. The upper end of the main gear 102 is fixedly connected to the lower end of the vertical rod 106. The drive motor 101 drives the main gear 102 to rotate, and the main gear 102 drives the vertical rod 106 to rotate.

[0024] A transmission gear 103 is rotatably connected inside the lower end of the housing 001. The transmission gear 103 meshes with the main gear 102. When the main gear 102 rotates, the transmission gear 103 rotates accordingly.

[0025] Gear 104 is rotatably connected inside the lower end of housing 001. Gear 104 is fixedly connected to cylinder 108. Gear 104 and transmission gear 103 are both provided with belt 105. When transmission gear 103 rotates, the kinetic energy of transmission gear 103 is transmitted to gear 104 through belt 105, so that gear 104 drives cylinder 108 to rotate.

[0026] A motor 202 is fixedly connected to the upper end of the cover 002, and a gear 203 is fixedly connected to the output end of the motor 202. The motor 202 drives the gear 203 to rotate.

[0027] The upper end of the turntable 204 is provided with a groove 205, and multiple tooth blocks 206 are arranged in a ring array on the inner wall of the groove 205. Gear 203 meshes with the tooth blocks 206, and the gear 203 drives the tooth blocks 206 to rotate, which in turn drives the turntable 204 to rotate.

[0028] In this invention, the operator feeds the powder metallurgy screw material into the feed cylinder 201. The motor 202 drives the gear 203 to rotate, which in turn pushes the gear block 206, which in turn drives the turntable 204 to rotate. The turntable 204 rotates, moving one of the storage troughs 207 below the feed cylinder 201. The material inside the feed cylinder 201 falls into the storage trough 207, which is now above the lower cover 209. The turntable 204 then rotates again, blocking the outlet of the feed cylinder 201 at the part of the turntable 204 without the storage trough 207. The storage trough 207 containing the material rotates above the outlet 210. At this point, due to gravity, the lower cover 209 rotates downwards, and the lower cover 209... 9. Partially, the material is slid into the discharge port 210, opening the slot 208. The material inside the storage tank 207 falls into the housing 001 through the slot 208 and the discharge port 210. The turntable 204 continues to rotate. The lower cover 209 is located inside the discharge port 210, and its side wall contacts the side of the discharge port 210. As the turntable 204 rotates, the lower cover 209 rotates into the slot 208, sealing the storage tank 207. At the same time, the turntable 204 rotates, and the part of the lower end of the turntable 204 without the slot 208 seals the discharge port 210, thereby preventing the powder from flying and being wasted in the subsequent mixing process and improving the overall protection of the device. Through the above steps, the material inside the feed cylinder 201 is transported into the housing 001.

[0029] After the material is introduced into the shell 001, the drive motor 101 drives the main gear 102 to rotate, which in turn drives the vertical rod 106 to rotate in the forward direction. The vertical rod 106 drives the multiple horizontal rods 107 on the side wall to rotate in the forward direction, and the transmission gear 103 rotates accordingly. Through the belt 105, the kinetic energy of the transmission gear 103 is transmitted to the gear 104, which drives the cylinder 108 to rotate in the reverse direction. The cylinder 108 drives the two rods 109 and the two levers 110 on the side wall to rotate in the reverse direction. Through the agitation in both directions, the material inside the shell 001 is fully mixed. After the material inside the shell 001 is fully mixed, the valve inside the discharge pipe 111 is opened, allowing the material to be discharged to the outside of the shell 001 through the discharge pipe 111. At the same time, the levers 110 push the material above the discharge pipe 111 to prevent a large amount of material from remaining inside the shell 001.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
