Description

Technical Field

[0001] This utility model relates to the technical field of grinders, and in particular to a grinder for mixing coffee beans with auxiliary materials. Background Technology

[0002] During the production and processing of coffee powder products, additional ingredients need to be added to enhance the flavor.

[0003] Currently, when processing coffee beans with additives, it is usually necessary to manually add coffee beans and additives to a grinder in a certain proportion, and then grind them together. However, manual control of the proportions of materials is not very accurate, which can easily lead to mixing errors and reduce the taste of the finished coffee bean mixture. In addition, the manual addition of coffee beans and additives to the grinder increases the labor intensity and reduces processing efficiency. Therefore, a grinder that can automatically measure and mix coffee beans and additives and automatically feed and convey them is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a coffee bean mixing and grinding machine to reduce the labor intensity of manual feeding, improve the working efficiency of the grinding machine and the accuracy of the mixing.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.

[0006] A coffee bean grinding machine with added auxiliary materials includes a housing, a grinding device, two sets of feed hoppers, two sets of cylinders, two sets of spiral blades, two sets of first motors, two sets of discharge pipes, and a controller. The grinding device is installed inside the housing, and a discharge port is provided at the bottom of the housing. The two sets of feed hoppers are respectively installed on the outer side walls of the left and right sides of the housing. The lower parts of the two sets of cylinders are respectively installed on the inner side walls of the two sets of feed hoppers, and each set of cylinders has a feed port at the bottom, which communicates with the inside of the two sets of feed hoppers. The upper and lower ends of the two sets of spiral blades are respectively rotatably installed on the inner side walls of the two sets of cylinders. The two sets of first motors are respectively installed at the top of the two sets of cylinders, and the output ends of the two sets of first motors are respectively concentrically connected to the top of the two sets of spiral blades. The two sets of discharge pipes are respectively connected to the upper part of the two sets of cylinders, and the output ends of the two sets of discharge pipes are respectively connected to the upper part of the housing. The controller is installed at the top of the housing and is electrically connected to the two sets of first motors.

[0007] First, coffee beans and auxiliary materials are placed in two separate feeding hoppers. The materials in the two hoppers enter the lower part of the two sets of cylinders through the feed inlets. Then, the controller controls the rotation of two sets of first motors, which drive the rotation of the two sets of cylinders. This causes the two sets of spiral blades to lift and convey the materials entering the lower part of the two sets of cylinders upwards. The conveyed materials then enter the housing through two sets of discharge pipes. Afterwards, the coffee beans and auxiliary materials are mixed and ground by the grinding device. The two sets of spiral blades lift and convey the materials, reducing the labor intensity of manual feeding and improving the working efficiency of the grinder. The controller controls the speed of the output end of the two sets of first motors, which facilitates the quantitative control of the feeding of coffee beans and auxiliary materials through the two sets of spiral blades, thereby improving the convenience and accuracy of automatic batching of the grinder.

[0008] Preferably, the powder grinding device includes a funnel, two sets of extrusion rollers, a filter screen, a rotating shaft, a first powder grinding rod, and a second motor. The funnel is installed on the upper part of the inner side wall of the box. The front and rear ends of the two sets of extrusion rollers are respectively rotatably installed on the inner side wall of the funnel, and the two sets of extrusion rollers are respectively rotated in opposite directions by a drive assembly. The filter screen is installed on the lower part of the inner side wall of the box. The bottom end of the rotating shaft is rotatably installed on the bottom of the inner side wall of the box. Multiple sets of first powder grinding rods are respectively circumferentially installed on the upper part of the outer side wall of the rotating shaft. The second motor is installed at the bottom of the box, and the output end of the second motor is concentrically connected to the bottom end of the rotating shaft.

[0009] Two sets of discharge pipes respectively transport coffee beans and auxiliary materials into the chamber. The material entering the chamber falls into the funnel, which guides and transports the material between two sets of extrusion rollers. The drive assembly drives the two sets of extrusion rollers to rotate in opposite directions, thereby crushing the material and improving the convenience of subsequent grinding. The crushed material continues to fall downwards, and the second motor drives the shaft to rotate. The rotation of the shaft drives multiple sets of first grinding rods to rotate, thereby grinding the material. The ground material settles on the top of the filter plate and is filtered through the filter plate, causing the ground material to fall to the bottom of the chamber. Large pieces of material settle on the top of the filter plate for further grinding, improving the grinding quality of the material.

[0010] Preferably, it also includes a first blower, a second blower, and a valve. The first blower is installed at the top of the housing and its output end is connected to the inside of the housing. The second blower is installed on the outer wall of the housing and its output end is positioned opposite to the discharge port at the bottom of the housing. The valve is connected to and installed at the discharge port of the housing.

[0011] When it is necessary to discharge the material at the bottom of the chamber, open the valve, and then turn on the first and second blowers. After the second blower is turned on, it blows air from top to bottom, causing the material powder attached to the filter screen to be conveyed downwards. Then, the material powder at the bottom of the chamber is blown out through the valve by the second blower, which improves the cleaning effect of material discharge in the chamber, while reducing the upward flying of material powder in the chamber and improving the discharge convenience of the pulverizer.

[0012] Preferably, the device also includes a collar, a bolt, and a collection bag. The collar is fitted onto the valve output end, the bolt is installed on the upper part of the collar, and the collection bag is installed on the right end of the collar, and the collection bag communicates with the inside of the valve. The collar is fitted onto the outer wall of the valve output end, and then the collar is tightened by rotating the bolt, thereby fixing the collar to the valve. Then, the material at the bottom of the box is discharged into the collection bag through the valve, improving the convenience of collecting finished materials.

[0013] Preferably, the device also includes multiple sets of second grinding rods, which are circumferentially installed on the inner side wall of the chamber, and the positions of the multiple sets of second grinding rods are staggered with those of the multiple sets of first grinding rods. After the multiple sets of first grinding rods rotate, they cooperate with the multiple sets of second grinding rods to grind the material, thereby improving the grinding efficiency of the grinding machine.

[0014] Preferably, it also includes a brush, which is installed on the outer wall of the second motor and the bottom end of the brush contacts the top surface of the filter screen. After the second motor rotates, it drives the brush to rotate, so that the brush sweeps the material on the top of the filter screen and reduces the clogging of the filter screen.

[0015] Preferably, it also includes two sets of cover plates, the upper parts of which are rotatably installed on the inner side wall of the box, and the two sets of cover plates are respectively set at the output ends of the two sets of discharge pipes; when the two sets of discharge pipes discharge materials, the weight of the materials pushes the two sets of cover plates to open, allowing the materials to enter the funnel; when the materials stop being conveyed, the two sets of cover plates are flipped outward and closed by natural gravity, improving the sealing effect of the output ends of the two sets of discharge pipes.

[0016] Due to the adoption of the above technical solutions, the technological progress achieved by this utility model is as follows.

[0017] This invention places coffee beans and auxiliary materials into two sets of feeding hoppers respectively. The materials in the two sets of feeding hoppers enter the lower part of the two sets of cylinders through the feeding inlets. Then, the controller controls the rotation of two sets of first motors, which drive the rotation of the two sets of cylinders. This causes two sets of spiral blades to lift and convey the materials entering the lower part of the two sets of cylinders upwards. The conveyed materials then enter the housing through two sets of discharge pipes. Afterwards, the coffee beans and auxiliary materials are mixed and ground by a grinding device. The two sets of spiral blades lift and convey the materials, reducing the labor intensity of manual feeding and improving the working efficiency of the grinder. The controller controls the speed of the output end of the two sets of first motors, which facilitates the quantitative control of the feeding of coffee beans and auxiliary materials through the two sets of spiral blades, thereby improving the convenience and accuracy of automatic batching of the grinder.

The materials in the two sets of feed hoppers 2 enter the lower part of the two sets of cylinders 3 through the feed inlets. Then, the controller 7 controls the rotation of the two sets of first motors 5, which drive the rotation of the two sets of cylinders 3. This causes the two sets of spiral blades 4 to lift and convey the materials entering the lower part of the two sets of cylinders 3 upwards.

[0026] In operation, coffee beans and auxiliary materials are first placed into two sets of feeding hoppers 2. The materials in the two sets of feeding hoppers 2 enter the lower part of two sets of cylinders 3 through the feeding inlets. Then, the controller 7 controls the rotation of two sets of first motors 5, which drive the rotation of the two sets of cylinders 3. This causes the two sets of spiral blades 4 to lift and convey the materials entering the lower part of the two sets of cylinders 3 upwards. The conveyed materials then enter the box 1 through two sets of discharge pipes 6. The materials entering the box 1 fall into the funnel 8, where they are guided and conveyed to the space between two sets of extrusion rollers 9. The drive assembly drives the two sets of extrusion rollers 9 to rotate in opposite directions, thereby crushing the materials. The crushed materials continue to fall downwards, and are further crushed by the rollers. The second motor 13 drives the rotating shaft 11 to rotate. After the rotating shaft 11 rotates, it drives multiple sets of first grinding rods 12 to rotate, thereby grinding the material into powder.
