Description

Technical Field

[0001] This utility model relates to the field of baking machine technology, specifically to a feeding device for a baking machine. Background Technology

[0002] Coffee roasting is the process of transforming the internal components of coffee beans. It involves roasting the beans at high temperatures, or baking, to create the coffee's unique color (similar to amber, depending on the desired level of roasting), flavor, and aroma. It is broadly categorized into light roast, medium roast, city roast, and dark roast.

[0003] When a coffee roaster is working, green coffee beans need to be placed into the hopper, and then a switching mechanism will move the beans into the roaster's drum. Due to the height of the roaster, some problems inevitably arise during the process of placing the beans into the hopper. Automatic feeding of green coffee beans is particularly important when roasting large quantities.

[0004] For example, the utility model patent with authorization announcement number CN214455063U discloses a negative pressure feeding device for a coffee roaster. This device, through the coordinated arrangement of a feeding hopper, a transmission pipeline, a closed hopper, a negative pressure pipeline, and a negative pressure device, can more conveniently and directly solve the feeding problem of a coffee roaster.

[0005] However, in actual use, when coffee beans are transferred from the closed hopper (feeding hopper) to the roasting machine, blockage may occur at the pipe inlet, which will affect the normal roasting process and cannot meet the usage requirements. Summary of the Invention

[0006] The purpose of this invention is to provide a feeding device for a baking machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A feeding device for a roaster includes: a feeding hopper mounted on the main body of the roaster, with a hopper cover installed at the upper end of the feeding hopper; a negative pressure component mounted on the hopper cover for creating negative pressure inside the feeding hopper; a feeding component mounted on the feeding hopper for cooperating with the negative pressure component to transfer coffee beans into the feeding hopper; and an anti-clogging component mounted at the lower end of the hopper cover for preventing coffee beans inside the feeding hopper from clogging the inlet; the anti-clogging component includes an anti-clogging shaft rotatably mounted at the lower end of the hopper cover, an anti-clogging paddle mounted on the anti-clogging shaft, and an anti-clogging motor mounted at the upper end of the hopper cover for driving the anti-clogging shaft to rotate.

[0008] As a preferred embodiment, the anti-blocking shaft extends into the pipe in the lower half of the feeding hopper, and the anti-blocking blade is spiral-shaped.

[0009] As a preferred embodiment, the upper end of the lid is provided with a negative pressure port, and the negative pressure assembly includes a negative pressure pipe installed in the negative pressure port, the other end of which is connected to a vacuum pump.

[0010] As a preferred embodiment, the feeding hopper is provided with a feeding port, and the feeding assembly includes a feeding pipe installed in the feeding port, the other end of which is connected to the storage hopper.

[0011] As a preferred embodiment, a support frame is also provided at the lower end of the storage hopper.

[0012] As a preferred embodiment, a solenoid valve is installed on the pipe in the lower half of the feeding hopper.

[0013] As a preferred embodiment, an auxiliary ring is also installed at the lower end of the bucket cover corresponding to the position of the negative pressure port. A connecting sleeve is screwed into the inner thread of the auxiliary ring, and an auxiliary retaining ring is fixed at the lower end of the connecting sleeve. Anti-slip texture is provided on the outer side of the auxiliary retaining ring.

[0014] Compared with existing technologies, the advantages of this invention are: by driving the anti-blocking shaft to rotate via an anti-blocking motor, the anti-blocking paddles rotate, thereby conveying coffee beans at a uniform speed through the pipeline. This effectively prevents coffee beans from clogging at the pipeline inlet, ensuring that the coffee beans are delivered into the roaster body, thus better meeting usage requirements. This invention has a reasonable structure, effectively preventing coffee beans from clogging in the hopper and facilitating their transfer to the roaster body, thus better meeting usage needs.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0018] Example: Please refer to Figures 1-4 A feeding device for a roaster includes: a feeding hopper 11 installed on the main body 1 of the roaster, a hopper cover 17 installed on the upper end of the feeding hopper 11, and a solenoid valve 4 installed on the pipe in the lower half of the feeding hopper 11; a negative pressure component installed on the hopper cover 17 for creating negative pressure in the feeding hopper 11; a feeding component installed on the feeding hopper 11 for cooperating with the negative pressure component to transfer coffee beans into the feeding hopper 11; and an anti-clogging component 2 installed at the lower end of the hopper cover 17 for preventing coffee beans in the feeding hopper 11 from clogging the pipe opening. The anti-clogging component 2 includes an anti-clogging shaft 22 rotatably installed at the lower end of the hopper cover 17, and an anti-clogging paddle 23 is also installed on the anti-clogging shaft 22. An anti-clogging motor 21 for driving the anti-clogging shaft 22 to rotate is also installed at the upper end of the hopper cover 17. In this embodiment, the anti-clogging shaft 22 extends into the pipe in the lower half of the feeding hopper 11, and the anti-clogging paddle 23 is spiral-shaped. To improve the sealing between the hopper 11 and the hopper cover 17, a sealing ring 19 is also installed in the sealing groove at the upper end of the hopper 11.

[0019] The working principle of this utility model is as follows: When it is necessary to transfer coffee beans in the feeding hopper 11 to the roaster body 1, the solenoid valve 4 is opened, and then the anti-blocking motor 21 is started. The anti-blocking motor 21 drives the anti-blocking shaft 22 to rotate, thereby realizing the rotation of the anti-blocking paddle 23, so as to convey the coffee beans into the pipeline at a uniform speed. This can effectively prevent the coffee beans from being blocked at the pipeline inlet, ensuring that the coffee beans can be conveyed into the roaster body 1, thereby better meeting the usage requirements.

[0020] As a further embodiment, the upper end of the hopper cover 17 is provided with a negative pressure port 151, and the negative pressure assembly includes a negative pressure pipe 15 installed in the negative pressure port 151. The other end of the negative pressure pipe 15 is connected to the vacuum pump 16. The feeding hopper 11 is provided with a feeding port 121, and the feeding assembly includes a feeding pipe 12 installed in the feeding port 121. The other end of the feeding pipe 12 is connected to the storage hopper 14. In this embodiment, a support frame 13 is also provided at the lower end of the storage hopper 14.

[0021] When it is necessary to transfer coffee beans into the feeding hopper 11, close the solenoid valve 4, and then turn on the vacuum pump to create a negative pressure in the feeding hopper 11. At the same time, the coffee beans stored in the storage hopper 14 can be sucked into the feed pipe 12 and then transferred into the feeding hopper 11.

[0022] As a further embodiment, an auxiliary ring 3 is installed at the lower end of the bucket cover 17 corresponding to the position of the negative pressure port 151. A connecting sleeve 33 is screwed onto the inner thread of the auxiliary ring 3. An auxiliary retaining ring 31 is fixed at the lower end of the connecting sleeve 33. Anti-slip texture 32 is provided on the outer side of the auxiliary retaining ring 31.

[0023] By setting anti-slip texture 32, it is easy to rotate the auxiliary retaining ring 31, which facilitates the installation of the auxiliary retaining ring 31. The auxiliary retaining ring 31 can prevent coffee beans from being sucked into the negative pressure tube 15.
