Description

Technical Field

[0001] This utility model relates to the technical field of raw material conveying equipment for beverage machines, specifically a raw material conveying mechanism for beverage machines. Background Technology

[0002] Currently, commercially available beverage machines generally use belt conveyors to transport powdered or granular ingredients from the hopper to the brewing station. However, existing structures generally suffer from two major drawbacks: difficulty in cleaning residual powder from the conveyor belt and cumbersome tension adjustment. On the one hand, after each feeding cycle, a large amount of powder often adheres to the surface of the conveyor belt. Current technology lacks scrapers, causing residual powder to fall into the machine's internal cavity with the return belt, contaminating the equipment and wasting ingredients. On the other hand, the drive wheel and frame are often rigidly fixed, leading to belt slackening after prolonged operation. Therefore, there is an urgent need for a compact material conveying mechanism that can be tensioned online and has a highly efficient self-cleaning function for the conveyor belt. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a raw material conveying mechanism for a beverage machine, which can solve the problems in the prior art.

[0004] This utility model is achieved through the following technical solution: A raw material conveying mechanism for a beverage machine includes a frame structure. A drive wheel structure is provided on the left side of the frame structure, and a driven wheel structure is connected and fixed on the right side of the frame structure. The drive wheel structure includes a drive wheel, and the driven wheel structure includes a driven wheel. A conveyor belt is wound around the outer surface of the drive wheel and the driven wheel, and the conveyor belt provides a power connection between the drive wheel and the driven wheel. The frame structure is characterized in that an infeed structure and an outlet structure are fixed on the top two sides respectively, a waste box is provided at the bottom of the frame structure, and a scraper structure is provided on the lower left side of the outlet structure for scraping and collecting powder impurities adhering to the conveyor belt into the waste box.

[0005] In a further technical solution, conveyor belt baffles are fixed on the front and rear sides of the outer surface of the conveyor belt.

[0006] A further technical solution involves fixing a first connecting plate to one side of the bottom of the frame structure and a second connecting plate to the other side of the bottom of the frame structure.

[0007] A further technical solution includes a drive wheel structure comprising a drive wheel mounting plate at the front and a rear. The drive wheel mounting plates are connected and fixed to the first connecting plate. The drive wheel is rotatably mounted between the drive wheel mounting plates. A motor mounting plate is fixed to one side of one of the drive wheel mounting plates. A motor is fixed to the motor mounting plate. The output shaft of the motor is poweredly connected to the drive wheel. A tensioning structure is also provided between the drive wheel mounting plate and the frame structure.

[0008] A further technical solution includes a feeding structure comprising a guide plate fixedly disposed on the top of the drive wheel mounting plate, the guide plate being connected and fixed between the front and rear sides of the drive wheel mounting plate.

[0009] In a further technical solution, the top of the guide plate is provided with an inclined surface that slopes downward to the right.

[0010] A further technical solution includes a tensioning structure comprising multiple oblong holes disposed within the drive wheel mounting plate. The frame structure comprises a main plate with a first threaded hole. A bolt is threaded into the first threaded hole and passes through the oblong holes to fix the drive wheel mounting plate and the main plate relative to each other. A sliding groove is also provided within the main plate. A side plate is fixed to one side of the drive wheel mounting plate and slides into the sliding groove. A flange is fixed to one side of the sliding groove and has a second threaded hole. A tensioning bolt is threaded into the second threaded hole and abuts against the side plate.

[0011] A further technical solution includes a driven wheel structure comprising a driven wheel mounting plate at the front and a driven wheel at the rear, and a frame structure comprising a main body plate.

The driven wheel is rotatably disposed between the driven wheel mounting plates.

[0012] A further technical solution includes a discharge structure comprising a hopper fixed to the right side of the driven wheel mounting plate, the hopper having an opening, a discharge port fixed at the bottom of the hopper, and a waste plate inclined toward the waste box fixed to the left side of the discharge port. The waste plate is located between the second connecting plate and the driven wheel, and the conveyor belt passes between the waste plate and the driven wheel. When the conveyor belt hangs down naturally, it contacts the waste plate, and the waste plate scrapes out the powder impurities on the outer surface of the conveyor belt and guides them into the waste box.

The conveyor belt 11 provides a power connection between the drive wheel 23 and the driven wheel 32. An infeed structure and an outlet structure are fixed on the top two sides of the frame structure, respectively. A waste box 26 is provided at the bottom of the frame structure. A scraper structure is also provided on the lower left side of the outlet structure to scrape and collect the powder impurities adhering to the conveyor belt 11 into the waste box 26. The powder impurities adhering to the conveyor belt 11 located at the lower side will also fall directly into the waste box 26 due to gravity.

[0028] Advantageously, conveyor belt baffles 12 are fixed on the front and rear sides of the outer surface of the conveyor belt 11. The conveyor belt baffles 12 are used to block the front and rear sides of the conveyor belt 11 to prevent the raw materials from leaking from the front and rear sides during conveying.

A flange is provided on one side of the first connecting plate 24 and the second connecting plate 28. The waste box 26 is placed on the flange, and the left and right sides of the waste box 26 are limited by the vertical parts of the first connecting plate 24 and the second connecting plate 28.

[0030] Advantageously, the drive wheel structure includes a drive wheel mounting plate 25 at the front and a drive wheel mounting plate 25 at the rear. The drive wheel mounting plate 25 is connected and fixed to the first connecting plate 24. A drive wheel 23 is rotatably arranged between the drive wheel mounting plates 25. A motor mounting plate 21 is fixed to one side of one of the drive wheel mounting plates 25. A motor 13 is fixed on the motor mounting plate 21. The output shaft of the motor 13 is poweredly connected to the drive wheel 23 through a coupling. A tensioning structure is also provided between the drive wheel mounting plate 25 and the frame structure.

[0031] Advantageously, the feeding structure includes a guide plate 22 fixedly disposed on the top of the drive wheel mounting plate 25. The guide plate 22 is connected and fixed between the front and rear drive wheel mounting plates 25. The top of the guide plate 22 is provided with an inclined surface that slopes downward to the right, and the inclined surface is used to guide the raw material.

[0032] Advantageously, the tensioning structure includes multiple oblong holes 42 disposed within the drive wheel mounting plate 25, and the frame structure includes a main plate 27. A first threaded hole 41 is disposed within the main plate 27, and a bolt is threadedly connected within the first threaded hole 41. The bolt passes through the oblong holes 42 to fix the drive wheel mounting plate 25 and the main plate 27 relative to each other. A sliding groove 44 is also disposed within the main plate 27. A side plate 43 is fixed to one side of the drive wheel mounting plate 25, and the side plate 43 slides into the sliding groove 44. A flange plate 46 is fixed to one side of the sliding groove 44, and a second threaded hole 45 is disposed within the flange plate 46. A tensioning bolt is threadedly connected within the second threaded hole 45, and the tensioning bolt abuts against the side plate 43. After the bolts in the oblong holes 42 and the first threaded hole 41 are loosened, by rotating the tensioning bolt in the second threaded hole 45, the tensioning bolt presses against the side plate 43, thereby driving the drive wheel mounting plate 25 to move to the left, which allows the drive wheel 23 to tension the conveyor belt 11.

[0033] Advantageously, the driven wheel structure includes a driven wheel mounting plate 29 at the front and a driven wheel at the rear, the frame structure includes a main plate 27, the main plate 27 is fixedly connected to the driven wheel mounting plate 29, the bottom of the driven wheel mounting plate 29 is fixedly connected to the second connecting plate 28, and a driven wheel 32 is rotatably provided between the driven wheel mounting plates 29.

[0034] Advantageously, the discharge structure includes a hopper 31 fixed to the right side of the driven wheel mounting plate 29. The hopper 31 has an opening, and a discharge port 51 is fixed at the bottom of the hopper 31. A waste plate 52 inclined towards the waste box 26 is fixed to the left side of the discharge port 51. The waste plate 52 is located between the second connecting plate 28 and the driven wheel 32. The conveyor belt 11 passes between the waste plate 52 and the driven wheel 32. When the conveyor belt 11 hangs down naturally, it contacts the waste plate 52. The waste plate 52 scrapes out the powder impurities on the outer surface of the conveyor belt 11 and guides them into the waste box 26.

[0035] Advantageously, the frame structure includes a main plate 27 at the front and a main plate 27 at the rear.

A fixed plate 33 is fixedly arranged between the main plates 27 at the top and bottom. The conveyor belt 11 moves on the upper surface of the upper fixed plate 33 and moves below the lower fixed plate 33.

[0036] When the raw material conveying mechanism is in operation, the motor 13 drives the drive wheel 23 to rotate. After the drive wheel 23 rotates, it drives the driven wheel 32 to rotate through the conveyor belt 11, so that the conveyor belt 11 has a tensioning function under the action of the tensioning structure. The conveyor belt 11 runs continuously clockwise. The raw materials in the external space are put in from above the guide plate 22, and then after passing through the conveyor belt 11, they are put into the hopper 31 and then fall from the discharge port 51. The raw material powder impurities adhering to the conveyor belt 11 are scraped by the waste plate 52 and collected into the waste box 26. Furthermore, due to gravity, the powder impurities on the outer surface of the lower conveyor belt 11 will also fall further into the waste box 26.

[0037] When adjusting the tension of the drive wheel mounting plate 25 and the drive wheel 23, after the bolts in the waist-shaped hole 42 and the first threaded hole 41 are loosened, the tensioning bolt in the second threaded hole 45 is rotated. After the tensioning bolt presses against the side plate 43, it can drive the drive wheel mounting plate 25 to move to the left, so that the drive wheel 23 can tension the conveyor belt 11.

[0038] The waste box 26 can also slide directly out from the front of the first connecting plate 24 and the second connecting plate 28 to facilitate personnel to empty the raw material powder and impurities in the waste box 26.

[0039] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without creative effort should be included within the protection scope of this utility model; therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
