Description

Technical Field

[0001] This utility model relates to the field of coffee processing technology, and in particular to a quantitative lifting machine. Background Technology

[0002] Coffee, one of the world's three major beverages, has a particularly strong bitter taste that stimulates the central nervous system, heart, and respiratory system. Moderate consumption can also relieve muscle fatigue and promote the secretion of digestive juices. Because it promotes kidney function and has a diuretic effect, helping the body excrete excess sodium ions, it is loved by a wide range of consumers. In the packaging and processing of coffee beans, lifting equipment is often used to facilitate operation and improve production efficiency.

[0003] According to the utility model patent CN214864301U, a coffee bean quantitative conveying device includes a feeding hopper. A connecting frame is fixedly connected to the bottom of the feeding hopper. A first support block is fixedly connected to the inner side of the connecting frame. A sliding column is fixedly connected to the top of the first support block. A filter plate is slidably connected to the outer side of the sliding column. A second support block is fixedly connected to the inner side of the connecting frame. A motor is fixedly connected to the rear end of the second support block. An elliptical block is fixedly connected to the end of the motor's main shaft. This utility model uses a gravity sensor to sense gravity and an electric telescopic rod to pull the quantitative plate to rotate inside the connecting frame, thereby quantitatively conveying coffee beans. The elliptical block improves sieving efficiency. A first spring mitigates the impact of falling coffee beans, and a second spring further buffers the impact, improving protection. It facilitates quantitative detection while reducing coffee bean drop rates, possessing broad market value and worthy of promotion.

[0004] While the above-mentioned technical solution can achieve the conveying of coffee beans, due to its structural design, the gravity sensor is located at the bottom of the metering plate, and the metering plate is supported by an electric push rod, making it difficult for the gravity sensor to perform its weighing function. Secondly, when coffee beans fall, they will accumulate in the middle of the two metering plates through the buffer plate, causing them to be subjected to force and rotate simultaneously. The gravity sensor will also be unable to perform its weighing function, thus failing to achieve the effect of quantitative conveying. Utility Model Content

[0005] The purpose of this invention is to provide a quantitative conveying machine that can quantitatively convey the amount of coffee beans according to actual packaging needs during the processing and packaging of coffee beans, thereby improving work efficiency and the accuracy of packaging coffee beans.

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

[0007] A quantitative elevator includes a fixed frame. A storage hopper is inclined downwards from front to back within the fixed frame. Control components communicating with the bottom left and right sides of the storage hopper are provided. A quantitative component communicating with the lower end of each control component is provided. A lifting component is provided at the rear end of the fixed frame. The lifting component includes a hollow lifting frame, a rotating shaft rotatably connected between the left and right sides of the inner wall of the lifting frame, synchronous pulleys respectively installed on the outer wall of the rotating shafts, synchronous belts fitted around and meshing with the outer walls of the two synchronous pulleys, and a plurality of lifting hoppers evenly spaced on the outer walls of the synchronous belts. A guide hopper, inclined downwards from front to back and outwards from the lower ends of the two quantitative components within the fixed frame, extends to the lower part of the inner wall of the lifting frame and is close to the lifting hopper. The guide hopper is wider at the top and narrower at the bottom.

[0008] A slot is provided above the rear end of the outer wall of the lifting frame. A guide hopper with an arc shape, open at both the front and bottom, is provided at the rear end of the outer wall of the lifting frame and communicates with the slot. A conveying component is provided at the lower end of the guide hopper at the rear end of the outer wall of the lifting frame and communicates with it. A support frame is provided at the upper end of one side of the outer wall of the lifting frame. A drive component is installed at the upper end of the support frame and is fixedly connected to the corresponding rotating shaft to drive the lifting component and the conveying component. A control box is provided on one side of the outer wall of the lifting frame. The control component, the metering component, and the drive component are all electrically connected to the control box.

[0009] By adopting the above technical solution, when using the device, first power it on and operate the control box to control the amount of coffee beans to be conveyed. Then, pour the coffee beans to be packaged into the storage hopper on the fixed frame. Then, the drive component drives the lifting component and the conveying component to work. The rotating shaft drives the corresponding synchronous pulley to rotate and drives the synchronous belt meshing with it to rotate, thereby driving the lifting hopper to rotate at a constant speed. The control component controls the coffee beans to enter the metering component. When the amount of coffee beans entering the metering component reaches the set value, the control component closes. Then, the metering component on one side of the guide hopper opens first, allowing the coffee beans to fall into the corresponding lifting hopper along the guide hopper. The synchronous belt lifts the lifting hopper containing coffee beans upward. When the next lifting hopper reaches the bottom of the guide hopper, another metering component opens to let the coffee beans fall. The first working control component and metering component continue to convey and weigh the coffee beans. When the coffee beans reach the top of the synchronous belt, the coffee beans will be thrown into the guide bin by the lifting hopper through the slot and fall onto the conveying component for subsequent conveying for packaging. This process is repeated to achieve the quantitative lifting effect during the packaging of coffee beans.

[0010] A further feature of this invention is that the control component includes a guide tube with openings at both the top and bottom, a groove formed on one side of the lower end of the guide tube, a baffle plate that is slidably connected to the groove and extends out of its opening end to block the opening at the lower end of the guide tube, a connecting frame disposed on one side of the upper end of the outer wall of the guide tube, and an electric push rod that is installed between the inner wall of the connecting frame and the outer wall of the baffle plate.

[0011] A further feature of this invention is that the quantitative component includes a quantitative cylinder with openings at both the top and bottom, a positioning shaft that is rotatably connected between the left and right sides of the lower end of the inner wall of the quantitative cylinder and extends out of its outer wall, a weighing device installed on the upper end of the positioning shaft and cooperating with the quantitative cylinder, a positioning frame disposed on one side of the lower end of the outer wall of the quantitative cylinder, and a first drive motor installed in the positioning frame and fixedly connected to one end of the positioning shaft.

[0012] By adopting the above technical solution, coffee beans can be weighed and then lifted and transported, improving the accuracy of quantitative lifting.

[0013] A further feature of this invention is that a buffer pad layer is provided at the rear end of the inner wall of the feed hopper.

[0014] By adopting the above technical solution, when the lifting bucket throws coffee beans into the feed hopper, the rigid contact force between the coffee beans and the inner wall of the feed hopper can be reduced, avoiding damage and preventing the coffee beans from rebounding and falling into the lifting frame.

[0015] A further feature of this invention is that the material conveying assembly includes an L-shaped material conveying pipe with openings at both ends, conveying rollers that are rotatably connected to the left and right sides of the inner walls of the material conveying pipe and extend out of their outer walls, a conveyor belt that is sleeved on the outer wall of the conveying rollers, a plurality of fixed grooves that are opened through the outer wall of the conveyor belt and are arranged at equal intervals along its length, and a receiving cloth that is flexibly arranged at the lower end of the inner wall of the fixed grooves.

[0016] By adopting the above technical solution, the combination of the fixed trough and the receiving cloth can ensure that each coffee bean in the lifting bucket is in a separate space when conveying coffee beans, thus further ensuring the quantitative delivery of coffee beans.

[0017] A further feature of this invention is that a counterweight block is provided at the bottom of the outer wall of each receiving cloth.

[0018] By adopting the above technical solution, the receiving cloth can be opened when each receiving cloth is in the upward position, which facilitates the accurate falling of coffee beans.

[0019] A further feature of this invention is that the drive assembly includes a second drive motor, a first pulley mounted on the outer wall of the power output shaft of the second drive motor, a second pulley disposed on one side of the outer wall of the conveying roller, and a transmission belt sleeved between the first pulley and the second pulley.

[0020] A further feature of this invention is that an infrared ranging sensor is installed on the front end of the inner wall of the lifting frame above the guide hopper.

[0021] By adopting the above technical solution, the distance between the front end of the outer wall of the elevator hopper and the infrared ranging sensor is monitored in real time, thereby further determining the opening time of the metering component, so that the falling coffee beans can fall accurately into the elevator hopper.

[0022] In summary, this utility model has the following beneficial effects:

[0023] Firstly, this utility model can quantitatively transport the amount of coffee beans according to actual packaging needs during the processing and packaging of coffee beans, thereby improving work efficiency and the accuracy of packaging coffee beans.

[0024] Secondly, the combination of the control component and the quantitative component of this utility model can not only control the amount of coffee beans lifted, but also allow the coffee beans in the storage hopper to fall in small, even amounts, further improving the quantitative lifting effect.

[0025] Thirdly, this utility model can drive both the lifting component and the material conveying component simultaneously with a single drive motor, thus reducing energy consumption;

[0026] Fourth, the infrared ranging sensor of this utility model can monitor the distance between the front end of the outer wall of the lifting hopper and the sensor in real time, thereby further determining the opening time of the metering component, so that the falling coffee beans can fall accurately into the lifting hopper.

The lifting assembly 3 includes a hollow lifting frame 31, a rotating shaft 32 rotatably connected between the upper and lower sides of the inner wall of the lifting frame 31 and the left and right sides respectively, a synchronous pulley 33 installed on the outer wall of the rotating shaft 32 respectively, a synchronous belt 34 that is fitted and meshed with the outer wall of the two synchronous pulleys 33, and a number of lifting buckets 35 that are evenly distributed on the outer wall of the synchronous belts 34. The fixed frame 1 is inclined downward from front to back at the lower end of the two metering components 2. An external guide hopper 36 extends to the lower part of the inner wall of the lifting frame 31 and is close to the lifting bucket 35. The guide hopper 36 is arranged with a larger top and a smaller bottom. An infrared ranging sensor 66 is installed above the guide hopper 36 at the front end of the inner wall of the lifting frame 31. A slot 4 is opened at the upper part of the rear end of the outer wall of the lifting frame 31. A guide bin 41 with an arc shape, open at both the front and bottom, is arranged at the rear end of the outer wall of the lifting frame 31 and communicates with the slot 4. A buffer pad 42 is arranged at the rear end of the inner wall of the guide bin 41.

[0041] A material conveying assembly 5 is provided at the lower end of the guide bin 41 on the rear end of the outer wall of the lifting frame 31. The material conveying assembly 5 includes an L-shaped material conveying pipe 51 with open ends, a conveying roller 52 that is rotatably connected to the left and right sides of the inner wall of the material conveying pipe 51 and extends out of its outer wall, a conveyor belt 53 that is sleeved on the outer wall of the conveying roller 52, a number of fixed grooves 54 that are opened through the outer wall of the conveyor belt 53 and are arranged at equal intervals along its length, and a flexible receiving cloth 55 that is respectively provided at the lower end of the inner wall of the fixed groove 54. A counterweight block 56 is provided at the bottom of the outer wall of each receiving cloth 55.

[0042] A support frame 6 is provided at the upper end of one side of the outer wall of the lifting frame 31. A drive component 61 is installed at the upper end of the support frame 6 and is fixedly connected to the corresponding rotating shaft 32 for driving the lifting component 3 and the conveying component 5. The drive component 61 includes a second drive motor 62, a first pulley 63 installed on the outer wall of the power output shaft of the second drive motor 62, a second pulley 64 provided on one side of the outer wall of the conveying roller 52, and a transmission belt 65 sleeved between the first pulley 63 and the second pulley 64. A control box 67 is provided on one side of the outer wall of the lifting frame 31. The control component 12, the metering component 2 and the drive component 61 are all electrically connected to the control box 67.

[0043] Usage: When in use, first power on the device and operate the control box 67 to control the amount of coffee beans to be conveyed by the metering component 2. Then, pour the coffee to be packaged into the storage hopper 11 on the fixed frame 1. The coffee beans in the storage hopper 11 will also fall into the guide tube 13 of the control component 12. Then, the drive component 61 on the support frame 6 drives the lifting component 3 and the conveying component 5 to work. The second drive motor 62 works and drives the first pulley 63 to rotate. At the same time, the transmission belt 65 and the second pulley 64 drive the conveying roller 52 on the conveying component to rotate, thereby driving the conveyor belt 53 to rotate. The rotating shaft 32 on the lifting frame 31 drives the corresponding synchronous pulley 33 to rotate and drives the synchronous belt 34 meshing with it to rotate, thereby driving the lifting hopper 35 to rotate at a constant speed. The control component 12 controls the coffee beans to enter the metering component 2.

[0044] The electric push rod 17 on the connecting frame 16 retracts and drives the baffle 15 to slide in the slide groove 14, thereby opening the lower end of the guide tube 13. The coffee beans will fall into the metering cylinder 21 of the metering component 2 and then be weighed by the weighing device 23. When the weight is close to the preset value, the electric push rod 17 gradually extends to return the baffle 15 to the initial state, so as to achieve precise control of the amount. When the amount of coffee beans reaches the set value, the control component 12 closes. When the lifting component 3 is working, the infrared distance sensor 66 in the lifting frame 31 will monitor the distance between itself and the outer wall of the corresponding lifting bucket 35 in real time. When the distance detected by it changes, the metering component 2 on one side of the guide bucket 36 opens first, the first drive motor 25 on the positioning frame 24 works and drives the weighing device 23 to flip through the positioning shaft 22, so that the coffee beans fall into the corresponding lifting bucket 35 along the guide bucket 36. The synchronous belt 34 then lifts the lifting bucket 35 containing coffee beans upward.

[0045] When the next lifting bucket 35 reaches below the guide bucket 36, the other metering component 2 opens to let the coffee beans fall. The first working control component 12 and metering component 2 continue to convey and weigh the coffee beans. When the coffee beans reach the top of the synchronous belt 34, the coffee beans will be thrown into the guide bin 41 by the lifting bucket 35 through the slot 4 and fall into the receiving cloth 55 in the fixed slot 54. The buffer layer 42 can not only avoid damage to the coffee beans due to rigid contact when throwing them, but also reduce the rebound rate of the coffee beans, allowing the coffee beans to fall quickly onto the conveying component 5. Since each receiving cloth 55 is equipped with a counterweight 56 ​​at the bottom, when the receiving cloth 55 is at its upper position, the receiving cloth 55 can be in a downward concave state to facilitate the receiving of the coffee beans. Then, it is conveyed to the packaging process by the conveyor belt 53. This process is repeated to achieve the quantitative lifting effect during the packaging process of coffee beans.

[0046] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment that make creative contributions as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
