Description

Technical Field

[0001] This utility model relates to the field of coffee bean production technology, and in particular to a quantitative weighing machine for coffee beans. Background Technology

[0002] In the coffee-making industry, precise quantitative weighing of coffee beans is a key step in ensuring the stability of coffee quality. Whether it is coffee shops making various coffee drinks or coffee production companies carrying out large-scale production and processing, precise control of the amount of coffee beans used is necessary.

[0003] Currently, the traditional method of weighing coffee beans mainly relies on manual operation. Workers use ordinary electronic scales to manually place coffee beans on the weighing pan, adding them while observing the weight display until the required weight is reached.

[0004] The existing technical solutions have the following drawbacks: manual operation is inefficient and cannot meet the demand for rapid and large-volume weighing. Moreover, manual weighing is easily affected by factors such as the operator's skill level and concentration, making it difficult to guarantee the accuracy of weighing. Utility Model Content

[0005] The purpose of this invention is to provide a coffee bean quantitative weighing machine to solve the problems existing in the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A coffee bean weighing machine includes a dispensing mechanism and a weighing mechanism disposed at the bottom of the dispensing mechanism. The weighing mechanism includes a shell, a round rod, a connecting block, a receiving groove, a moving rod, and weights. The shell is a shell with a completely open bottom. Both front ends of the two side walls of the shell are provided with oblong holes. The round rod is fixedly installed at the center position inside the shell and is arranged in a left-right direction. The connecting block is rotatably mounted on the round rod. A forward extension plate extends from the front side of the connecting block. The moving rod passes through the extension plate. Both ends of the moving rod pass through the oblong holes and extend to the outside of the shell. The weights are detachably installed on the left end of the moving rod. A limit block is fixedly installed on the right end of the moving rod. A rearward extension bar extends from the rear side of the connecting block. The receiving groove is fixedly installed on the rear side of the extension bar.

[0008] By adopting the above technical solution, the extraction mechanism sends the extracted coffee beans into the receiving tank. Using the lever principle, the coffee beans are quantitatively weighed by weights. When the weight of the coffee bean end is greater than the weight of the weight end, the connecting block will move clockwise around the round rod, causing the coffee beans in the receiving tank to slide out of the receiving tank and then be discharged from the bottom of the outer shell. Thus, the quantitative extraction of coffee beans is completed without manual operation.

[0009] In a further embodiment, the receiving slot includes a vertical plate, a horizontal plate, a connecting plate, and a switch plate. The top of the outer casing has a first through hole that runs vertically through it. The rear end of the switch plate has a second through hole corresponding to the first through hole. The switch plate is slidably connected to the top of the outer casing. The vertical plate and the horizontal plate are arranged vertically. The horizontal plate is fixedly installed on the rear side of the bottom end of the vertical plate. The left and right sides of the vertical plate and the horizontal plate are both in contact with the inner wall of the outer casing. The top end of the vertical plate is rotatably connected to the bottom end of the connecting plate. The top end of the connecting plate is rotatably connected to the switch plate.

[0010] By adopting the above technical solution, when the round rod rotates clockwise, the vertical plate will drive the switch plate to slide backward through the connecting plate. Then, when the coffee beans in the receiving tank slide down, the solid part of the right end of the switch plate will block the first through hole, and the coffee beans in the extraction mechanism cannot continue to be delivered to the receiving tank. When the round rod moves counterclockwise to reset, the first through hole and the second through hole will connect, and the coffee beans can continue to be delivered to the receiving tank, thereby ensuring the quantitative extraction of coffee beans.

[0011] In a further embodiment, the extraction mechanism includes a blower, a cyclone separator, a feed pipe, and a feed funnel. The blower is fixedly installed on the top of the cyclone separator, and the air inlet of the blower is connected to the interior of the cyclone separator. One end of the feed pipe is connected to the feed inlet of the cyclone separator, and the other end of the feed pipe is connected to the discharge outlet of the feed funnel.

[0012] By adopting the above technical solution, the blower generates suction, which draws coffee beans from the feed hopper into the cyclone separator through the feed pipe, thus completing the automatic extraction of coffee beans without manual operation.

[0013] In a further embodiment, a silicone pad is fixedly installed on the inner wall of the cyclone separator.

[0014] By adopting the above technical solution, the collision between coffee beans and the inner wall of the cyclone separator is prevented, thus ensuring the integrity of the coffee beans.

[0015] In a further embodiment, a dust collection bag is detachably installed at the air outlet of the fan.

[0016] The above technical solution is used to absorb dust in the air discharged from the air outlet.

[0017] In a further embodiment, the movable rod includes a first crossbar and a second crossbar, the second crossbar being vertically disposed at the left end of the first crossbar, and the connection between the first crossbar and the second crossbar being a rounded transition.

[0018] By adopting the above technical solution, the weights can be detachably installed on the second crossbar, thereby allowing different weights to be replaced to achieve quantitative extraction of coffee beans of different weights.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. The extracted coffee beans are fed into the receiving tank through the extraction mechanism. Using the lever principle, the coffee beans are weighed quantitatively by weights. When the weight of the coffee beans is greater than the weight of the weights, the connecting block will move clockwise around the rod, causing the coffee beans in the receiving tank to slide out and be discharged from the bottom of the outer shell. This allows for the quantitative extraction of coffee beans without manual operation. Attached Figure Description

[0028] Example 1:

[0029] like Figures 1-4 As shown, a coffee bean quantitative weighing machine includes an extraction mechanism 1 and a weighing mechanism 2 disposed at the bottom of the extraction mechanism 1. The weighing mechanism 2 includes a shell 21, a round rod 22, a connecting block 23, a receiving groove 24, a moving rod 25, and a weight 26. The shell 21 is a shell with a completely open bottom. Both sides of the shell 21 have waist-shaped holes at their front ends. The round rod 22 is fixedly installed in the center position inside the shell 21. The round rod 22 is arranged in the left and right direction. The connecting block 23 is rotatably installed on the round rod 22. A forward extension plate 27 extends from the front side of the connecting block 23. The moving rod 25 passes through the extension plate 27. Both ends of the moving rod 25 pass through the waist-shaped holes and extend to the outside of the shell 21. The weight 26 is detachably installed on the left end of the moving rod 25. A limit block 28 is fixedly installed on the right end of the moving rod 25. A rearward extension strip 29 extends from the rear side of the connecting block 23. The receiving groove 24 is fixedly installed on the rear side of the extension strip 29.

[0030] The receiving slot 24 includes a vertical plate 241, a horizontal plate 242, a connecting plate 243, and a switch plate 244. The top of the outer casing 21 has a first through hole extending vertically. The rear end of the switch plate 244 has a second through hole corresponding to the first through hole. The switch plate 244 is slidably connected to the top of the outer casing 21. The vertical plate 241 and the horizontal plate 242 are vertically arranged. The horizontal plate 242 is fixedly installed on the rear side of the bottom end of the vertical plate 241. The left and right sides of the vertical plate 241 and the horizontal plate 242 are both in contact with the inner wall of the outer casing 21. The top end of the vertical plate 241 is rotatably connected to the bottom end of the connecting plate 243, and the top end of the connecting plate 243 is rotatably connected to the switch plate 244. The extraction mechanism 1 includes a fan. The device includes a machine 11, a cyclone separator 12, a feed pipe 13, and a feed funnel 14. The feed pipe 13 is a flexible hose. The blower 11 is fixedly installed on the top of the cyclone separator 12. The air inlet of the blower 11 is connected to the inside of the cyclone separator 12. One end of the feed pipe 13 is connected to the feed inlet of the cyclone separator 12, and the other end of the feed pipe 13 is connected to the discharge outlet of the feed funnel 14. A silicone pad is fixedly installed on the inner wall of the cyclone separator 12. A dust collector bag 3 is detachably installed at the air outlet of the blower 11. The moving rod 25 includes a first crossbar and a second crossbar. The second crossbar is vertically set at the left end of the first crossbar, and the connection between the first crossbar and the second crossbar is a rounded transition.

[0031] Specific implementation process: The blower 11 starts operating and generates strong suction. The suction is transmitted to the cyclone separator 12 through the air inlet connected to the inside of the cyclone separator 12. At this time, under the action of suction, coffee beans enter the feed pipe 13 from the feed funnel 14, and are then sucked into the cyclone separator 12 through the feed pipe 13, completing the automatic extraction of coffee beans. At the same time, the silicone pad fixedly installed on the inner wall of the cyclone separator 12 can effectively prevent coffee beans from colliding with the inner wall of the cyclone separator 12, thereby ensuring the integrity of the coffee beans. The dust collector bag 3, which can be detachably installed at the air outlet of the blower 11, can absorb the dust in the air discharged from the air outlet. The extracted coffee beans are sent to the weighing mechanism 2. The coffee beans enter the receiving tank 24 through the first through hole and the second through hole. As the weight of the coffee beans increases, when the front of the connecting block 32... When the weight at one end is less than the weight at the other end, the connecting block 23 will rotate clockwise around the round rod 22. The extension plate 27 on the front side of the connecting block 23 drives the moving rod 25 to move in the waist-shaped holes at the front ends of the two side walls of the outer casing 21. When the connecting block 23 rotates clockwise, the vertical plate 241 drives the switch plate 244 to slide backward through the connecting plate 243. The solid part at the right end of the switch plate 244 blocks the first through hole at the top of the outer casing 21, and the coffee beans in the extraction mechanism 1 cannot continue to be conveyed to the receiving tank 24. When the coffee beans in the receiving tank 24 slide down due to the rotation of the connecting block 23 and are discharged from the bottom of the outer casing 21, the connecting block 23 moves counterclockwise to reset, and the first through hole and the second through hole corresponding to the rear end of the switch plate are connected. The extraction mechanism 1 can then continue to convey coffee beans to the receiving tank 24. This cycle is repeated to realize the automatic quantitative weighing of coffee beans.
