Description

A powder conveying device for the production of cemented carbide rods Technical Field

[0001] This utility model relates to the field of cemented carbide rod production technology, and in particular to a powder conveying device for cemented carbide rod production. Background Technology

[0002] Hard alloy rods, also known as tungsten carbide rods, are composite materials made from refractory metal compounds (hard phases) and binder metals through powder metallurgy. They possess high hardness, wear resistance, strength, and toughness, as well as good heat resistance and corrosion resistance.

[0003] Reference to the utility model patent with authorization announcement number CN210285684U, a conveying device for nickel-based alloy powder production is disclosed, including a workbench, a conveying box, and a first rotary motor. First support columns are welded to the four corners of the bottom surface of the workbench. A conical funnel is arranged on the bottom surface of the workbench between the four sets of first support columns, and the conveying box is located directly below the outlet of the conical funnel. Three sets of second support columns are welded to the bottom surface of the conveying box. The conveying box has a semi-circular groove structure and is horizontally positioned directly below the conical funnel. A support plate is welded to the end of the conveying box directly below the conical funnel, and the first rotary motor is fixedly installed on the top surface of the support plate by bolts. A single screw conveying shaft is horizontally arranged inside the conveying box, and the single screw conveying shaft is rotatably connected to the conveying box via bearings.

[0004] The aforementioned patent uses a single screw conveyor shaft to transport powder materials. This conveying method is inconvenient for long-distance transport. In addition, a conveying box is set on the outside of the single screw conveyor shaft, and material residue will remain during the conveying process, which is difficult to clean. Its applicability is poor. In order to solve the shortcomings of the above technology, we propose a powder conveying device for the production of cemented carbide rods. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a powder conveying device for the production of cemented carbide rods.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A powder conveying device for producing cemented carbide rods includes a support frame for producing cemented carbide rods, a conveyor belt disposed inside the support frame, and a powder cleaning mechanism disposed on the left side of the support frame. The powder cleaning mechanism includes a mounting plate, sleeves symmetrically fixedly mounted on the right side of the mounting plate, a rotating plate disposed on the right side of the mounting plate, a rotating shaft fixedly connected to the side of the rotating plate, the rotating shaft being rotatably inserted into the inside of the sleeve, a telescopic cylinder symmetrically hinged between the rotating plate and the lower side of the mounting plate, a return spring fixedly mounted inside the telescopic cylinder, and a mounting slot opened on the right side of the rotating plate, a brush holder being inserted into the mounting slot, and a brush being fixedly mounted on the side of the brush holder.

[0008] Furthermore, several transverse baffles are evenly distributed on the outer side of the conveyor belt, and the right side of the rotating plate is close to the left side of the conveyor belt.

[0009] Furthermore, a sealing ring is embedded at the telescopic port of the telescopic cylinder.

[0010] Furthermore, a number of limiting screws are screwed onto the lower side of the rotating plate, with the upper end of each limiting screw threaded through to the inside of the mounting slot and abutting against the brush holder.

[0011] Furthermore, connecting folding plates are fixedly connected to both sides of the mounting plate, and the connecting folding plates are screwed to the support frame.

[0012] Furthermore, a rotating roller is rotatably mounted on the inner side of the support frame, the conveyor belt is sleeved on the outer side of the rotating roller, and a drive motor is fixedly mounted on the outer wall of the support frame. The output end of the drive motor rotates through to the inner side of the support frame and is fixedly connected to the rotating roller.

[0013] Furthermore, a controller is fixedly installed on the outer wall of the support frame.

[0014] Furthermore, a material guide trough is provided below the rotating plate, and a connecting column is fixedly connected between the material guide trough and the support frame.

[0015] Compared with related technologies, the powder conveying device for the production of cemented carbide rods proposed in this utility model has the following beneficial effects:

[0016] In this invention, a powder conveying device for producing cemented carbide rods is described. Through a powder cleaning mechanism, a rotating plate within the mechanism is kept horizontal under the action of a return spring inside a telescopic cylinder. A brush mounted on the side of the rotating plate remains in contact with the conveyor belt. When the conveyor belt conveys powder to the left, the brush sweeps the conveyor belt, preventing powder residue. Simultaneously, transverse baffles on the conveyor belt cause the rotating plate to rotate downwards. When the upper and lower transverse baffles rotate to the left, the rotating plate, under the action of the return spring, strikes the transverse baffles, knocking off any remaining powder. The striking action of the rotating plate and the continuous brushing action of the brush effectively clean the powder residue on the conveyor belt, preventing powder residue. Furthermore, this invention utilizes a conveyor belt, facilitating long-distance transport. The conveying interface is in direct contact with the outside environment, simplifying future maintenance and making it highly adaptable. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Referring to Figures 1-7, a powder conveying device for the production of cemented carbide rods includes a support frame 1 for the production of cemented carbide rods, a conveyor belt 5 is provided on the inner side of the support frame 1, and a powder cleaning mechanism 9 is provided on the left side of the support frame 1. The powder cleaning mechanism 9 includes a mounting plate 91, a sleeve 93 is symmetrically fixedly mounted on the right side of the mounting plate 91, a rotating plate 95 is provided on the right side of the mounting plate 91, a rotating shaft 94 is fixedly connected to the side of the rotating plate 95, the rotating shaft 94 is rotatably inserted into the inner side of the sleeve 93, a telescopic cylinder 96 is symmetrically hinged between the rotating plate 95 and the lower side of the mounting plate 91, a return spring 97 is fixedly mounted on the inner side of the telescopic cylinder 96, an installation slot 99 is opened on the right side of the rotating plate 95, a brush holder 910 is inserted into the inner side of the installation slot 99, and a brush 911 is fixedly mounted on the side of the brush holder 910.

[0027] In this method, a rotating roller 4 is rotatably installed on the inner side of the support frame 1, and a conveyor belt 5 is sleeved on the outer side of the rotating roller 4. A drive motor 3 is fixedly installed on the outer wall of the support frame 1. The output end of the drive motor 3 rotates through to the inner side of the support frame 1 and is fixedly connected to the rotating roller 4. A controller 2 is fixedly installed on the outer wall of the support frame 1.

[0028] With the above configuration, when the drive motor 3 rotates, it can drive the inner rotating roller 4 to rotate, which in turn drives the conveyor belt 5 to rotate, so as to transport the powder.

[0029] In this configuration, several transverse baffles 6 are evenly distributed on the outer side of the conveyor belt 5, and the right side of the rotating plate 95 is close to the left side of the conveyor belt 5.

[0030] With the above configuration, the right side of the rotating plate 95 is close to the left side of the conveyor belt 5. When the transverse baffle 6 on the conveyor belt 5 rotates to the upper side of the rotating plate 95, the rotating plate 95 will rotate downward under the action of the transverse baffle 6. At this time, the brush 911 brushes relative to the conveyor belt 5, sweeping away the residual powder on the conveyor belt 5. When the transverse baffle 6 rotates through the contact space with the rotating plate 95, the rotating plate 95 will return upward under the action of the return spring 97 inside the telescopic cylinder 96, striking the next rotating transverse baffle 6 and knocking off the powder on the conveyor belt 5.

[0031] In this method, a sealing ring 98 is embedded at the telescopic port of the telescopic cylinder 96.

[0032] By setting it in the above manner, the sealing ring 98 prevents powder from entering the inside of the telescopic cylinder 96, thus ensuring the normal functionality of the telescopic cylinder 96.

[0033] In this method, a number of limiting screws 912 are screwed onto the lower side of the rotating plate 95. The upper end of the limiting screw 912 is screwed through to the inside of the mounting slot 99 and the upper end of the limiting screw 912 abuts against the brush holder 910.

[0034] With the above-described configuration, the limiting screw 912 abuts against the brush holder 910, ensuring that the brush holder 910 is stably inserted into the mounting slot 99. When the brush needs to be replaced, the limiting screw 912 is loosened, and the brush holder 910 is slid out of the mounting slot 99. Then, the brush holder 910 of the new brush 911 is inserted into the mounting slot 99. This makes replacing the brush 911 convenient and ensures that the brush 911 is securely fixed.

[0035] In this configuration, connecting plates 92 are fixedly connected to both sides of the mounting plate 91, and the connecting plates 92 are screwed to the support frame 1.

[0036] With the above-described setup, the entire powder cleaning mechanism 9 is installed on the left side of the support frame 1 via screw connection, making installation convenient and secure.

[0037] In this method, a guide trough 7 is provided below the rotating plate 95, and a connecting column 8 is fixedly connected between the guide trough 7 and the support frame 1.

[0038] With the above-described configuration, the guide trough 7 is positioned below the rotating plate 95, allowing the powder that is knocked down and brushed to fall onto the guide trough 7. The guide trough 7 is inclined, and the powder that falls onto the guide trough 7 slides down to the position to be processed.

[0039] The working principle of the powder conveying device for cemented carbide rod production provided by this utility model is as follows:

[0040] In use, powder for producing cemented carbide rods is fed onto conveyor belt 5. The drive motor 3 is turned on to drive conveyor belt 5 to rotate to the left, conveying the powder. The brush 911 installed on the side of the rotating plate 95 on the left side of conveyor belt 5 is in contact with conveyor belt 5 to brush and sweep the conveyor belt 5, brushing the residual powder down onto the guide chute 7. The conveyor belt 5 conveys the powder down onto the rotating plate 95. The rotating plate 95 is flipped by the action of the transverse baffle 6, causing the rotating plate 95 to tilt downward, thus causing the powder on the rotating plate 95 to slide down onto the guide chute 7. When the transverse baffle 6 rotates past the contact space with the rotating plate 95, the rotating plate 95 is reset upward by the action of the return spring 97 inside the telescopic cylinder 96, striking the next rotating transverse baffle 6, and knocking the powder off the conveyor belt 5, which finally falls onto the guide chute 7, avoiding powder residue on the conveyor belt 5.

[0041] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
