Description

Technical Field

[0001] The utility model relates to the field of screw carburizing equipment, in particular to a feeding device for a mesh belt furnace for carburizing. Background Art

[0002] Self-tapping screws, also known as quick-thread screws, are quick-install fasteners made of steel with a galvanized and passivated surface. Self-tapping screws are mostly used to connect thin metal plates. During the processing of self-tapping screws, in order to improve the hardness and wear resistance of the screw surface, the surface needs to be carburized. Carburizing treatment refers to a chemical heat treatment process in which the steel is heated and kept warm in a carburizing medium to allow carbon atoms to penetrate into the surface layer in order to increase the carbon content of the steel surface and form a certain carbon concentration gradient. In the prior art, the carburizing process of the screws is generally achieved through a mesh belt furnace.

[0003] For example, the patent with authorization announcement number CN114990470A discloses a surface carburizing treatment equipment for the production of carbon steel self-tapping screws. A material receiving trough and a discharge plate are arranged on the support plate. The support shaft drives the brush roller to clean the mesh conveyor belt, and the cleaned coke is collected through the material receiving trough. The rotation of the support shaft also drives the discharge assembly and the cleaning mechanism. The discharge assembly drives the coke in the material receiving trough to be transported to the discharge ports on both sides thereof, so that the coke slides along the discharge plate to the discharge channel and is discharged out of the carburizing device. The cleaning mechanism cleans the coke on the discharge plate, thereby reducing the workload of the staff. There is no need to stop the machine to clean the mesh conveyor belt, so that the carburizing device can continuously carburize the material and improve production efficiency.

[0004] The above patent uses a mesh conveyor belt to transport the screws, and uses a carburizing device to heat and carburize the screws. However, the disadvantage of the above technology is that when the mesh belt furnace carries the screws, the screws are usually dumped at one end of the mesh belt, which causes a large number of screws to accumulate in the middle of the conveyor mesh belt, while there are fewer screws on both sides of the conveyor mesh belt, resulting in uneven distribution of the screws entering the mesh belt furnace body.

[0005] Therefore, it is necessary for us to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] Furthermore, the conveying motor is fixedly mounted on a motor mounting seat, and the motor mounting seat is fixedly mounted on the rear side of a roller frame mounting plate on the right side of the conveying bracket.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0025] See also Figure 1-4 , a feeding device for a mesh belt furnace for carburizing, comprising a conveying mesh belt 1;

[0026] The conveyor mesh belt 1 is mounted on the conveyor bracket 2, and a material balancing device 3 is also provided on the top right side of the conveyor mesh belt 1.

[0027] The conveying support 2 includes a bottom plate 201 and a top plate 208. The left and right sides of the top of the bottom plate 201 are respectively fixedly connected with roller frame mounting plates 202. The top of the roller frame mounting plate 202 is fixedly installed with a first shaft seat 203 at the front and back. The first shaft seat 203 is rotatably connected with a first roller shaft 204 through a bearing. A roller 205 is fixedly sleeved on the first roller shaft 204. The conveying mesh belt 1 is drivingly connected between the two rollers 205.

[0028] The front and rear ends of the first roller shaft 204 on the right side of the conveying bracket 2 pass through the first shaft seat 203, and the rear end of the first roller shaft 204 is connected to the output shaft of the conveying motor 206 through a coupling transmission;

[0029] Specifically, the conveying motor 206 is fixedly mounted on the motor mounting seat 207, and the motor mounting seat 207 is fixedly mounted on the rear side of the roller frame mounting plate 202 on the right side of the conveying bracket 2;

[0030] The top plate 208 is located directly above the bottom plate 201, and the top of the bottom plate 201 is fixedly connected to the top plate through the column 209, wherein the conveyor mesh belt 1 is close to the top of the top plate 208, and the top plate 208 is mainly used to support the conveyor mesh belt 1 to prevent the middle section of the conveyor mesh belt 1 from sinking;

[0031] The conveying support 2 also includes a tensioning roller 5, which is rotatably arranged on a tensioning shaft 501, and both ends of the tensioning shaft 501 are fixedly mounted on a third shaft seat 502, and a waist hole is opened on the third shaft seat 502, and the third shaft seat 502 is fixedly mounted on the side wall of the roller frame mounting plate 202 by bolts (not shown in the figure);

[0032] At the same time, in order to prevent the screws from falling from the sides of the front and rear sides of the conveyor mesh belt 1 after the screws are laid flat, two side baffles 209 are symmetrically arranged on the top of the top plate 208. The side baffles 209 are located on the front and rear sides of the conveyor mesh belt 1. The side baffles 209 are used to prevent the screws from falling from the conveyor mesh belt.

[0033] The side baffle 209 includes a bottom edge portion 210 and a side edge portion 211 which are perpendicularly arranged to each other, and the bottom edge portion 210 is fixedly connected to the top plate 208;

[0034] The material balancing device 3 includes a second roller 301 and a material balancing roller 302. The material balancing roller 302 is fixedly sleeved on the second roller 301. The front and rear ends of the second roller 301 are rotatably connected to a second shaft seat 303 through bearings. The second shaft seat 303 is fixedly installed on the top right end of the top plate 208.

[0035] The front end of the second roller shaft 301 passes through the second shaft seat 301 and is fixedly connected to a driven pulley 304, and the front end of the first roller shaft 204 is fixedly connected to a driving pulley 305, which is driven by a transmission belt 306.

[0036] The cross section of the material distribution roller 302 is drum-shaped, and the diameter of the material distribution roller 302 gradually decreases from the middle to both sides;

[0037] Two sets of guide plates 4 are also provided on the right side of the material balancing device 3. The structure of the guide plates 4 is similar to that of the side baffles 209. The two sets of guide plates 4 are open as a whole.

[0038] like Figure 5 As shown, in certain embodiments of the present scheme, two groups of guide blades 307 are further provided on the surface of the material-distributing roller 302, wherein the two groups of guide blades 307 are symmetrically arranged along the middle of the material-distributing roller 302, and the rotation directions of the two groups of guide blades 307 are arranged in opposite directions.

[0039] like Figure 6 As shown, when the feeding device for the mesh belt furnace for carburizing in this scheme is reused, it is similar to a surface carburizing treatment equipment for the production of carbon steel self-tapping screws in the background technology, and also includes a heating furnace 9 (mesh belt furnace) erected above the feeding device for the mesh belt furnace for carburizing. After the screws are evenly arranged through this scheme, they enter the heating furnace for uniform carburizing treatment.

[0040] When this solution is put into use, the conveying motor 206 drives the conveying mesh belt 1 to convey the screws to be carburized into the heating furnace 9. Figure 2 For example, at this time, the conveying motor 206 drives the roller 205 in front of it to rotate counterclockwise, and then drives the conveying mesh belt 1 to rotate counterclockwise, so that the screws to be carburized on the conveying mesh belt 1 are conveyed to the left side, and at this time, the transmission belt 306 also drives the material leveling roller 302 above the conveying mesh belt 1 to rotate counterclockwise, and because the material leveling roller 302 is a drum-shaped structure with a thick middle and thin ends; when the screws piled up in the middle of the conveying mesh belt 1 encounter the material leveling roller 302 rotating counterclockwise, the screws contacting the material leveling roller 302 are pushed to the right and to the front and back sides, so that the screws on the conveying mesh belt 1 are flattened as much as possible;

[0041] The advantage of the present solution of using a drum-shaped material-distributing roller 302 is that when the material-distributing roller 302 contacts the pile of screws being pushed, initially only the thicker middle part of the material-distributing roller 302 contacts the pile of screws, and its contact area is small, so the pile of screws can be squeezed apart more easily; whereas if a material-distributing roller 302 of uniform diameter is used, the screws are easy to contact directly and difficult to push apart, resulting in the screws in the middle of the pile of screws not being squeezed apart to the sides, but being squeezed by the material-distributing roller 302 directly in the middle of the pile of screws, thereby damaging the screws or the material-distributing roller.

[0042] Similarly, two groups of guide blades 307 are provided on the surface of the material distribution roller 302, which also has the advantage that when contacting with the screw pile, the screws can be contacted with a smaller contact area (guide blades), and then the screw pile can be easily pushed away.

[0043] At the same time, the material distribution roller 302 can also be made of high temperature resistant rubber material, so as to reduce the impact between the material distribution roller and the screw.
