Description

Technical Field

[0001] This utility model belongs to the technical field of powder metallurgy molding green blank conveying equipment, specifically relating to a conveying channel for burner cap green blanks. Background Technology

[0002] Powder metallurgy is a mature, efficient, and economical method for manufacturing burner caps, especially suitable for mass production of complex-shaped caps. A large number of gas stove caps (domestic and commercial) on the market are manufactured using powder metallurgy, particularly those made of stainless steel with complex burner hole designs. Its core advantage lies in its ability to achieve near-net-shape forming of complex structures at a relatively low cost and extremely high efficiency.

[0003] The conveyor trough for powder metallurgy molding green blanks is a key piece of equipment connecting the pressing and sintering processes, and its core function is to achieve lossless transfer of the green blanks. The green blank is the intermediate state of metal powder after pressing and before sintering, and its characteristics directly affect the subsequent sintering quality and the performance of the final product. Powder metallurgy green blanks have poor mechanical properties, most notably low strength and high brittleness.

[0004] When the molded green preform is ejected from the mold, a large amount of powdery raw material is usually ejected simultaneously. The powder and green preform mix, and during the transfer process in the conveyor trough, the powder and green preform need to be separated. Conventional methods use airflow separation and vibrating sieving to separate the powder, but airflow separation can pollute the atmospheric environment near the equipment, and vibrating sieving can cause the green preform to crack.

[0005] In order to overcome the shortcomings of airflow sorting and vibrating screening, this utility model aims to provide a conveying channel for burner cap green blanks. Utility Model Content

[0006] The purpose of this invention is to provide a conveying channel for burner cap green blanks to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A conveying channel for burner cap green blanks includes a channel groove, a plurality of screens are provided at the bottom of the channel groove, a detachable receiving hopper is provided at the bottom surface of the channel groove, and a dust suction pipe is connected to the bottom of the receiving hopper; the receiving hopper is located directly below the screens; and a connector is provided at one end of the channel groove.

[0008] Preferably, the upper and lower edges of the bottom surface of the screen are respectively provided with a pull-out rail one; a material receiving hopper is provided at the pull-out rail, and a pull-out rail two is provided on the upper and lower sides of the material receiving hopper respectively; the pull-out rail one and the pull-out rail two cooperate to pull and pull, and the material receiving hopper can be pulled and moved left and right; a baffle is provided at one end of the pull-out rail one, and the material receiving hopper is pulled out or inserted from the other end of the pull-out rail one.

[0009] Preferably, the receiving hopper is provided with a pull handle on one side.

[0010] Preferably, the upper end of the channel groove is hinged with a connector, the connector is provided with a plurality of bolt fixing holes, and a support foot is provided at the upper part of the bottom surface of the channel groove.

[0011] Preferably, two screens are arranged sequentially at the bottom of the channel groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) The present invention provides a conveying channel for a burner cap green blank, which adopts a screen structure. When the powder and the green blank pass through the screen, the powder can fall into the receiving hopper. (2) The present invention provides a conveying channel for a burner cap green blank, which is connected to a dust suction pipe at the receiving hopper. The powder passing through the screen can be sucked in by the dust suction pipe, which strengthens the tendency of the powder to enter the screen. (3) The present invention provides a conveying channel for the burner cover green blank, which adopts a detachable pull-out structure for the receiving hopper, and can be disassembled and cleaned.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] A conveying channel for burner cap green blanks includes a channel trough 1. Two screens 2 are provided at the bottom of the channel trough 1. When powder and green blanks pass through the screens 2, the powder can fall through the screens 2, achieving separation of the powder and green blanks. Two detachable receiving hoppers 3 are provided on the lower surface of the channel trough 1, each corresponding to one of the two screens 2, and located directly below each screen 2. The receiving hoppers 3 are used to collect the powder falling from the screens 2. A suction pipe 4 is connected to the bottom of the receiving hoppers 3, and a negative pressure device is connected to the end of the suction pipe 4. The powder passing through the screens 2 can be sucked in by the suction pipe 4, strengthening the tendency of the powder to enter the screens 2.

[0016] The receiving hopper 3 is detachable and can be removed from the bottom of the channel groove 1. To achieve this detachability, a pull-out rail 5 is provided at the upper and lower edges of the bottom surface of the screen 2, with the receiving hopper 3 located at the pull-out rail 5. A second pull-out rail 6 is provided on the upper and lower sides of the receiving hopper 3. The pull-out rails 5 and 6 work together to allow the receiving hopper 3 to move left and right. A pull-out handle 11 is provided on one side of the receiving hopper 3, greatly facilitating its movement. To limit excessive pulling of the receiving hopper 3, a baffle 7 is provided at one end of the pull-out rail 5, allowing the receiving hopper 3 to be pulled out or inserted from the other end of the pull-out rail 5.

[0017] A connector 8 is hinged to the upper end of the channel groove 1. The connector 8 has two bolt fixing holes 9, and the channel groove 1 is fixed to the front end equipment through the connector 8. A support foot 10 is provided on the bottom surface of the channel groove 1 to support the channel groove 1.
