[0001] The utility model relates to the technical field of coffee bean polishing equipment, in particular to a coffee bean polishing machine. Background Art

[0002] Coffee bean polishing is a step in the coffee bean processing process, which refers to the process of grinding and cleaning the surface of the coffee beans. The main purpose of polishing is to improve the appearance of the coffee beans, making them smoother and more uniform, and also to remove some surface imperfections and impurities.

[0003] In the prior art, such as the Chinese patent number: CN209219180U, a coffee bean polishing machine includes a device shell, a feed port, a discharge port, and a supporting device, wherein the feed port is arranged at the upper left of the device shell, the discharge port is arranged at the lower right of the device shell, the supporting device is arranged at the bottom of the device shell, a central rotating shaft is arranged in the device shell, an auger device is arranged on the central rotating shaft, a heating device and a cooling device are arranged above the device shell, the heating device is arranged at one end of the feed port, the cooling device is arranged at one end of the discharge port, a filter layer is arranged at the bottom of the device shell, the filter layer is arranged as a conical surface structure and is tightly connected to the bottom of the device shell, a filter chute is arranged at the lower part of the filter layer, and a leakage port is arranged at one end of the filter chute. The utility model can effectively increase the friction between coffee beans, improve the efficiency of silver skin removal, and at the same time, the surface of the coffee beans is not damaged during the polishing process.

[0004] Although the above scheme has the above advantages, the disadvantage of the above scheme is that before the polishing operation, the traditional coffee bean polishing machine only has a rough screening process. For some high-end coffee beans, the quality of each bean needs to meet higher standards. The coffee beans cannot be screened more carefully, and coffee beans of different specifications cannot be screened, resulting in the required specifications of the coffee beans not meeting the standards, reducing the overall quality of the coffee beans. In addition, when screening, a large amount of floating dust will adhere to the surface of the coffee beans. As the screening proceeds, the floating dust will float everywhere and cannot be blown away, which greatly affects the workers' operation and reduces the screening efficiency before the coffee beans are polished. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that before the polishing operation, the traditional coffee bean polishing machine only has a rough screening process. For some high-end coffee beans, the quality of each bean needs to meet a higher standard. The coffee beans cannot be screened more carefully, and coffee beans of different specifications cannot be screened, resulting in the required specifications of the coffee beans not meeting the standards, reducing the overall quality of the coffee beans, and during the screening, a large amount of floating dust will adhere to the surface of the coffee beans.

[0020] The technical effect of adopting the above further solution is: by turning on the second motor, the high-speed rotation of the stirring rod is used to polish the coffee beans that have been screened.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are:

[0022] 1. The utility model pours unscreened coffee beans onto the surface of the first sieve plate, then turns on the external power supply of motor 1, starts motor 1, and the output end of motor 1 starts to drive one of the cylinders to rotate forward. As the cylinder rotates rapidly, the two rotating plates and the cross bar also rotate accordingly. At this time, the other cylinder also rotates with the two rotating plates and maintains the same speed. Through the continuous rotation of the two rotating plates, the cross bar starts to make circular motion and gradually pulls the pull-out rod to swing up and down in a cycle. As the pull-out rod swings, the vertical plate and the top moving plate also start to shake repeatedly. At this time, the two first swinging rods start to swing at a uniform speed in the inner wall of one group of fixed rods and swing at the shaking frequency of the moving plate. The other two second swinging rods also swing at a uniform speed in the other group of fixed rods. The uniform swinging of the first swinging rod and the second swinging rod provides stable support for the moving plate as a whole to prevent the shaking frequency of the moving plate from being too large. Through the overall shaking of the moving plate, the unscreened coffee beans begin to pass through the first sieve The mesh plate completes the first layer of screening, and the coffee beans that fail to pass the screening of the first mesh plate will slide into the square plate with the overall swing of the moving plate. The coffee beans that complete the first layer of screening will pass through the second mesh plate for the second layer of screening, and the coffee beans that fail to pass the second layer of screening will slide onto the surface of the guide plate to be collected. At this time, the coffee beans that pass the two layers of screening will fall directly into the shell, and then the staff turns on motor 2 and uses the high-speed rotation of the stirring rod to polish the coffee beans that have completed the screening. Through the above operations, the layer-by-layer screening of the coffee beans is completed, and more detailed screening is provided. The staff can obtain larger coffee beans from the coffee beans that slide out of the square plate, medium-sized coffee beans from the coffee beans that slide out of the guide plate, and smaller coffee beans from the coffee beans that pass through the second mesh plate, thereby obtaining three different specifications of coffee beans, thereby achieving more detailed screening of the coffee beans, screening of coffee beans of different specifications, preventing the coffee beans from not meeting the required specifications, and improving the overall quality of the coffee beans.

[0023] 2. The utility model uses two cylinders to rotate forward, and the other cylinder drives the rotating column one to rotate forward. The continuous rotation of the rotating column one drives the belt to rotate forward. The belt rotates vertically and drives the rotating column two to rotate at the same time. As the rotating column two rotates, the paddle column movably connected to the inner wall of the outer cover also moves at a high speed as the rotating column two rotates. The high-speed rotation of the paddle column is used to generate wind force. When pouring coffee beans, the floating dust generated is blown away to prevent the workers' line of sight from being blocked. Therefore, the floating dust can be blown away during screening, and the workers' operations are prevented from being affected by the floating dust, thereby improving the screening efficiency before polishing the coffee beans.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Example 1, please refer to Figure 1-5The utility model provides a technical solution: a coffee bean polishing machine, comprising a shell 1, a support plate 102 is fixedly connected at the top edge of the shell 1, a plurality of fixed rods 108 are fixedly connected to one side of the inner wall of the support plate 102 near the top, the plurality of fixed rods 108 are evenly divided into two groups, one group of fixed rods 108 are movably connected to first swing rods 109 on both sides of the inner wall, the other group of fixed rods 108 are movably connected to second swing rods 110 on both sides of the inner wall, one side of the outer surface of the two first swing rods 109 is movably connected to a moving plate 103, both sides of the outer surface of the moving plate 103 are movably connected to one side of the outer surface of the two second swing rods 110, the inner wall of the moving plate 103 is fixedly embedded with a first screen plate 104, the inner wall of the moving plate 103 is fixedly connected with a square plate 105 on both sides, the inner wall of the moving plate 103 is fixedly connected with a second screen plate 106 on both sides, the inner wall of the moving plate 103 is fixedly connected with a guide plate 107 on both sides. Two horizontal plates 114 are fixedly connected to one side of the outer surface of the frame plate 102, one side of the outer surface of one of the horizontal plates 114 is fixedly connected to a support plate 113, a motor 112 is fixedly installed at the top center of the support plate 113, the inner sides of the outer surfaces of the two horizontal plates 114 are movably connected to two cylinders 115, one end of one cylinder 115 is fixedly connected to the output end of the motor 112, one end of the two cylinders 115 are fixedly connected to a rotating plate 116, the inner side of the outer surface of the rotating plate 116 is fixedly connected to a horizontal bar 117, the outer surface of the horizontal bar 117 is movably sleeved with a pull rod 118, a vertical plate 119 is fixedly connected to the bottom near the center of the second screen plate 106, the inner walls of the vertical plate 119 are movably connected to the outer surfaces of the pull rod 118, a motor 2 120 is fixedly installed on one side of the outer surface of the outer shell 1, the output end of the motor 2 120 is fixedly connected to a stirring rod 111, and the outer surface of the outer shell 1 is fixedly connected to a plurality of supporting legs 101.

[0033] In this embodiment, unscreened coffee beans are poured onto the surface of the first screen plate 104, and then the external power supply of the motor 112 is turned on to start the motor 112. The output end of the motor 112 starts to drive one of the cylinders 115 to rotate forward. As the cylinder 115 rotates rapidly, the two rotating plates 116 and the cross bar 117 also rotate accordingly. At this time, the other cylinder 115 also rotates with the two rotating plates 116 and maintains the same speed. Through the continuous rotation of the two rotating plates 116, the cross bar 117 starts to make a circular motion and gradually pulls the pull rod 118 upward. The vertical plate 119 and the top moving plate 103 also begin to shake repeatedly as the pull rod 118 swings. At this time, the two first swinging rods 109 begin to swing at a uniform speed in the inner wall of one set of fixed rods 108, and swing at the shaking frequency of the moving plate 103. The other two second swinging rods 110 also swing at a uniform speed in the other set of fixed rods 108. The uniform swinging of the first swinging rods 109 and the second swinging rods 110 provides a stable support for the moving plate 103 as a whole, preventing the shaking frequency of the moving plate 103 from being too large. The coffee beans that have not been screened begin to pass through the first screen plate 104 to complete the first layer of screening. The coffee beans that have not passed the first screen plate 104 will slide into the square plate 105 as the moving plate 103 swings as a whole. The coffee beans that have completed the first layer of screening will pass through the second screen plate 106 for the second layer of screening. The coffee beans that have not passed the second layer of screening will slide onto the surface of the guide plate 107 to be collected. At this time, the coffee beans that have passed the two layers of screening will directly fall into the shell 1. Then the staff turns on the motor 2 120 and uses the high-speed rotation of the stirring rod 111 to stir the coffee beans that have completed the screening. Polishing operation is performed. Through the above operation, the coffee beans are screened layer by layer, and more detailed screening is provided. The staff can obtain larger-sized coffee beans from the coffee beans sliding out of the square plate 105, and medium-sized coffee beans from the coffee beans sliding out of the guide plate 107 and smaller-sized coffee beans from the coffee beans passing through the second screen plate 106, thereby obtaining three coffee beans of different specifications, thereby achieving more detailed screening of the coffee beans, screening of coffee beans of different specifications, preventing the coffee beans from failing to meet the required specifications, and improving the overall quality of the coffee beans.

[0034] Embodiment 2, as Figure 1-5 As shown, one side of the outer surface of the bracket plate 102 is fixedly connected to the outer cover 202, and both sides of the inner wall of the outer cover 202 are movably connected to the blade column 204, one end of the blade column 204 is fixedly connected to the rotating column 203, and the outer surface of the rotating column 203 is connected to the belt 201 through a pulley, and one end of the other cylinder 115 is fixedly connected to the rotating column 1 2, and the outer surface of the rotating column 1 2 is connected to one side of the inner wall of the belt 201 through a pulley.

[0035] In this embodiment, two cylinders 115 rotate forward, and the other cylinder 115 drives rotating column 1 2 to rotate forward. The continuous rotation of rotating column 1 2 drives belt 201 to rotate forward. Belt 201 rotates vertically and drives rotating column 2 203 to rotate at the same time. As rotating column 203 rotates, paddle column 204 movably connected to the inner wall of outer cover 202 also moves at high speed as rotating column 203 rotates. The high-speed rotation of paddle column 204 generates wind force, which blows away floating dust generated when pouring coffee beans to prevent blocking the workers' line of sight. Therefore, floating dust can be blown away during screening, and workers' operations are prevented from being affected by floating dust, thereby improving the screening efficiency before polishing coffee beans.

[0036] Working principle: Before the polishing operation, the staff first pours the unscreened coffee beans onto the surface of the first screen plate 104, then turns on the external power supply of the motor 112, starts the motor 112, and the output end of the motor 112 starts to drive one of the cylinders 115 to rotate forward. As the cylinder 115 rotates rapidly, the two rotating plates 116 and the cross bar 117 also rotate accordingly. At this time, the other cylinder 115 also rotates with the two rotating plates 116 and maintains the same speed. Through the continuous rotation of the two rotating plates 116, the cross bar 117 starts to make a circular motion and gradually pulls the pull rod 118 to swing up and down in a cycle. As the pull rod 118 swings, the vertical plate 119 and the top moving plate 103 also start to rotate in the reverse direction. The moving plate 103 is shaken repeatedly, and the two first swinging rods 109 begin to swing at a uniform speed in the inner wall of one group of fixed rods 108, and swing with the shaking frequency of the moving plate 103. The other two second swinging rods 110 also swing at a uniform speed in another group of fixed rods 108. The uniform swinging of the first swinging rods 109 and the second swinging rods 110 provides stable support for the moving plate 103 as a whole to prevent the shaking frequency of the moving plate 103 from being too large. Through the overall shaking of the moving plate 103, the unscreened coffee beans begin to pass through the first screen plate 104 to complete the first layer of screening. The coffee beans that have not passed the screening of the first screen plate 104 will slide into the square plate 105 with the overall swinging of the moving plate 103. The coffee beans that have completed the first layer of screening will pass through the second screen plate The coffee beans that have not passed the second screening will slide onto the surface of the guide plate 107 to be collected. At this time, the coffee beans that have passed the two screenings will directly fall into the shell 1. Then the staff turns on the motor 2 120 and uses the high-speed rotation of the stirring rod 111 to polish the coffee beans that have completed the screening. Through the above operations, the layer-by-layer screening of the coffee beans is completed and more detailed screening is provided. The staff can obtain larger-sized coffee beans from the coffee beans that slide out of the square plate 105, medium-sized coffee beans from the coffee beans that slide out of the guide plate 107, and smaller-sized coffee beans from the coffee beans that pass through the second screen plate 106, thereby obtaining three different-sized coffee beans, thereby achieving the goal of being able to screen the coffee beans. More detailed screening can be carried out, and coffee beans of different specifications can be screened to prevent the coffee beans from not meeting the required specifications, thereby improving the overall quality of the coffee beans. When the two cylinders 115 rotate forwardly, the other cylinder 115 drives the rotating column 1 2 to rotate forwardly, and the belt 201 is driven to rotate forwardly through the continuous rotation of the rotating column 1 2. The belt 201 rotates vertically and drives the rotating column 2 203 to rotate. As the rotating column 203 rotates, the paddle column 204 movably connected to the inner wall of the outer cover 202 also moves at a high speed as the rotating column 203 rotates. The high-speed rotation of the paddle column 204 is used to generate wind force, and when the coffee beans are poured in, the floating dust generated is blown away to prevent the workers' sight from being blocked, thereby achieving the goal of blowing away the floating dust during screening.It prevents workers from being affected by floating dust and improves the screening efficiency before coffee bean polishing.
