Description

Technical Field

[0001] This application relates to the technical field of nut cleaning equipment, and in particular to a fully automatic nut cleaning device. Background Technology

[0002] Nuts often have metal shavings remaining after manufacturing, requiring cleaning. A nut cleaning device is a piece of equipment used to remove oil, metal shavings, and other impurities from the surface of nuts.

[0003] Nut cleaning devices typically consist of a main body, a cleaning tank, a spray system, and a material guiding assembly. The spray system uses high-pressure water jets to rinse the nuts inside the cleaning chamber, while the material guiding assembly mechanically agitates the nuts, resulting in a multi-faceted rinse that removes dirt from their surfaces. Some devices are also equipped with an ultrasonic vibration system, which uses high-frequency vibration to create cavitation effects in the cleaning agent, further enhancing the cleaning effect.

[0004] Currently, after cleaning, the surface of some nuts may not be thoroughly cleaned, requiring the addition of cleaning agent to mix with the nuts. The cleaning agent is injected evenly into the roller manually or using a pump, and the rotation of the roller promotes the mixing of the nuts and cleaning agent. However, due to the small size and large number of nuts, uneven mixing can easily occur, which will affect the cleaning effect of the nuts. Summary of the Invention

[0005] To improve the cleaning effect of nuts, this application provides a fully automatic nut cleaning device.

[0006] The fully automatic nut cleaning device provided in this application adopts the following technical solution: An automatic nut cleaning device includes a cleaning unit and a feeding device installed on one side of the cleaning unit. The cleaning unit includes a first cleaning cabinet and a second cleaning cabinet. The discharge port of the first cleaning cabinet is equipped with a cleaning device for removing residues from the surface of the nuts. The discharge port of the cleaning device is equipped with a mixing device for promoting the mixing of cleaning liquid and nuts. The discharge port of the mixing device is equipped with a filter box connected to the feeding device. The mixing device includes a cabinet, a spiral cylinder, and a drive mechanism. The spiral cylinder is rotatably mounted on the cabinet. The drive mechanism is installed inside the cabinet and is used to drive the spiral cylinder to rotate. Spiral blades for promoting the mixing of cleaning liquid and nuts and pushing the nuts forward are fixedly connected to the inner wall of the spiral cylinder. A guide plate connected to the spiral cylinder is fixedly connected to the side of the cabinet near the cleaning device. A pump is fixedly connected to the side of the cabinet near the guide plate. One end of the pump is connected to a liquid storage tank connected to the cabinet. The other end of the pump is fixedly connected to a movable nozzle for guiding the cleaning liquid into the spiral cylinder.

[0007] By adopting the above technical solution, firstly, the entire process of nut cleaning can be automated by setting up a cleaning device, a feeding device, a cleaning device, a mixing device, etc., reducing manual intervention and improving production efficiency; secondly, the cleaning device can remove residues from the surface of the nut, and the mixing device promotes the mixing of cleaning liquid and nut through a spiral drum and spiral blades, ensuring that the nut can fully contact the cleaning liquid, thereby improving the cleaning effect.

[0008] Optionally, the spiral cylinder is a three-section type, and the spiral blades are provided in three sections. The pitch of the spiral blades at both ends is greater than the pitch of the spiral blades in the middle section. The spiral blades in the middle section are used to reduce the forward distance of the nut.

[0009] By adopting the above technical solution, the three-section design of the spiral drum allows the larger pitch at both ends to quickly push the nut into the spiral drum, while the smaller pitch in the middle slows down the forward speed of the nut, allowing the nut to stay in the spiral drum for a longer time, thus mixing more thoroughly with the cleaning fluid. This ensures that the cleaning fluid can act evenly on each nut, improving the cleaning effect.

[0010] Optionally, the two ends of the spiral cylinder are cylindrical hollow tubes, and the middle part is an elliptical hollow tube.

[0011] By adopting the above technical solution, the cylindrical part facilitates the smooth entry and exit of the nut, while the elliptical part can increase the contact area and residence time of the nut in the screw cylinder, which can create a more complex flow state of the cleaning fluid, thereby better promoting the mixing of the cleaning fluid and the nut and further improving the cleaning effect.

[0012] Optionally, the lower end of the filter box is provided with a collection box for collecting cleaning fluid, and one end of the collection box is fixedly connected to a circulation pipe connected to a storage tank.

[0013] By adopting the above technical solution, the collection box is connected to the storage tank through a circulation pipe, which allows the cleaning liquid to be collected and recycled, reducing waste of cleaning liquid, lowering production costs, reducing environmental pollution, and improving the operational stability and reliability of the entire cleaning device.

[0014] Optionally, a baffle is hinged to one side of the guide plate. The baffle is used to cover the feed inlet of the guide plate and is located on the discharge port side of the impurity removal device. A limit switch that cooperates with the baffle is fixedly connected to one side of the guide plate.

[0015] By adopting the above technical solution, the baffle is used to cover the feed inlet of the guide plate, which can effectively prevent the material from flowing back during the conveying process and ensure that the material can smoothly enter the mixing device. When the baffle rotates and connects with the contact of the limit switch, the pump runs, realizing the automatic control of the pump and improving the automation level and operating efficiency of the equipment.

[0016] Optionally, the contact of the limit switch is located on one side of the baffle, and the limit switch is electrically connected to the pump. When the baffle rotates and connects with the contact of the limit switch, the pump operates.

[0017] By adopting the above technical solution, precise control of the pump can be achieved. The pump will only operate when the baffle is rotated to a specific position, avoiding ineffective operation of the pump, saving energy, extending the service life of the equipment, and realizing coordinated work between the equipment through the limit switch and the electrical connection of the pump, thereby improving the reliability and stability of the entire system.

[0018] Optionally, the lower end of the baffle near the guide plate is arc-shaped, and an elastic pad is fixedly connected to the side of the baffle near the guide plate.

[0019] By adopting the above technical solution, the collision between the material and the baffle when entering the guide plate can be reduced, avoiding damage to the material due to the collision, thereby reducing equipment wear, extending the service life of the equipment, and ensuring the integrity of the nut.

[0020] Optionally, a vibration device for removing moisture from the surface of the nuts is provided on one side of the discharge port of the second cleaning cabinet, and a collection box for collecting the nuts is provided on one side of the discharge port of the vibration device.

[0021] By adopting the above technical solution, not only can the moisture on the surface of the nut be effectively removed, allowing the nut to be better dried or otherwise treated in subsequent processes, but the cleaned nuts can also be easily collected, improving production efficiency and reducing manual operation.

[0022] Optionally, the impurity removal device includes a fixed frame, a vibrating plate, and a vibrating motor. Damping rods are fixedly connected to the four corners of the upper end of the fixed frame. The upper end of the piston rod of each damping rod is fixedly connected to the four corners of the vibrating plate. A vibrating spring is sleeved on the outside of each damping rod and fixedly connected between the fixed frame and the vibrating plate. The vibrating motor is fixedly connected to the lower side of the vibrating plate. A conical drain port is provided at the lower end of the vibrating plate.

[0023] By adopting the above technical solution, the vibration motor drives the vibratory plate to vibrate, which can effectively remove impurities and residues from the surface of the nut, improve the cleanliness of the nut, and the conical drain port can easily discharge the removed impurities, prevent impurities from accumulating in the device, and keep the equipment clean and efficient.

[0024] Optionally, both the first and second cleaning cabinets include a body, a filter cartridge, and stirring blades. The stirring blades are rotatably connected to the inner wall of the filter cartridge. The feed inlet of the filter cartridge is fixedly connected to the upper end of the body. One side of the filter cartridge has an opening communicating with the discharge outlet of the body. A drive box for driving the stirring blades is fixedly installed on one side of the body. The inner wall of the filter cartridge is provided with a spray pipe. One side of both the first and second cleaning cabinets is fixedly connected to a circulating water tank. The upper ends of the two circulating water tanks are respectively fixedly connected to a high-pressure pump connected to the spray pipe.

[0025] By adopting the above technical solution, the stirring blades are rotatably connected to the inner wall of the filter cartridge, which can fully stir the nut and make the nut fully contact with the cleaning liquid. The spray pipe can spray the nut to further improve the cleaning effect. In addition, each cleaning cabinet is connected to a circulating water tank on one side. The cleaning liquid is delivered to the spray pipe through a high-pressure pump, realizing the recycling of the cleaning liquid, saving resources and reducing costs.

[0026] In summary, this application has the following beneficial effects: 1. This application removes residues from the surface of the nut using a cleaning device, and then uses the spiral cylinder and spiral blades of the mixing device to increase the residence time and mixing effect of the nut, ensuring that the nut can be evenly contacted with the cleaning liquid, thereby improving the uniformity and thoroughness of cleaning.

[0027] 2. This application can perform multiple cleanings on the surface of the nut using the first and second cleaning cabinets, which can effectively remove stubborn stains or residues from the surface of the nut, reduce waste of cleaning solution, lower production costs, reduce environmental pollution, and thus extend the service life of the equipment.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0031] This application discloses a fully automatic nut cleaning device.

[0032] Reference Figure 1 The cleaning device 1 includes a first cleaning cabinet 11 and a second cleaning cabinet 12. Each of the first and second cleaning cabinets 11 and 12 has a feeding device 2 on one side. The outlets of the two feeding devices 2 are located above the inlets of the first or second cleaning cabinet 11 and 12, respectively. The feeding devices 2 are used to stably transport nuts into the first or second cleaning cabinet 11 or 12 for cleaning. In this application, the feeding device 2 is a conveyor belt lifting feeding device 2, which is prior art and will not be described further here. A debris removal device 3 is provided at the outlet of the first cleaning cabinet 11. The debris removal device 3 cleans residual debris on the nuts after initial cleaning by vibration. A mixing device 4 is provided at the outlet of the debris removal device 3 for mixing the cleaning agent with the nuts. A filter box 5 is provided below the outlet of the mixing device 4, and the lower end of the other feeding device 2 is fixedly connected to one side of the filter box 5, for guiding the nuts in the filter box 5 into the second cleaning cabinet 12 for secondary cleaning. The discharge port of the second cleaning cabinet 12 is equipped with a vibration device 7 for removing water stains from the surface of the nuts. The water then falls into the collection box 8 through the discharge port of the vibration device 7 for unified collection and processing. In this application, the structure of the vibration device 7 is the same as that of the impurity removal device 3, but the purpose is different.

[0033] Reference Figure 1 , Figure 2 and Figure 6The impurity removal device 3 and the vibration device 7 are interconnected devices, both including a fixed frame 31, four corner damping rods 34 fixedly installed on the upper end of the fixed frame 31, and a vibrating disk 32 fixedly connected to the upper end of the piston rods of the four damping rods 34. Vibration springs 35 are fitted on the outer sides of the damping rods 34 and fixedly connected between the fixed frame 31 and the vibrating disk 32. The vibration springs 35 provide elastic support for the vibrating disk 32, and through their cooperation with the damping rods 34, allow the vibrating disk 32 to vibrate within a certain range, thereby extending the service life of the equipment and improving its operational stability. A vibration motor 33 for driving the vibration of the vibrating disk 32 is fixedly connected to the lower side of the vibrating disk 32. The upper end of the vibrating disk 32 has multiple grid-like holes, the diameter of which is smaller than the diameter and width of the nut, preventing the nut from falling out of these holes and allowing residual debris or liquid on the nut to fall through. The upper edge of the vibratory feeder 32 is fixedly connected with a protective plate to prevent the nut from falling off due to vibration. The lower end of the vibratory feeder 32 is provided with a conical drain port 36, which allows the debris or liquid that is shaken off to be discharged through the conical drain port 36 for easy collection and treatment.

[0034] Reference Figure 2 , Figure 3 The mixing device 4 includes a cabinet 41 and a spiral cylinder 42 rotatably mounted inside the cabinet 41. Spiral blades 421 are fixed to the inner wall of the spiral cylinder 42. When the spiral cylinder 42 rotates, the spiral blades 421 push the nut forward, promoting uniform mixing of the nut and the cleaning agent. In this application, the spiral cylinder 42 is a hollow roller composed of cylindrical ends and an elliptical middle section joined together. The pitch of the spiral blades 421 at both ends, located on the inner wall of the cylindrical portion of the spiral cylinder 42, is 10cm to 15cm, which increases the forward distance of the nut and improves the nut's conveying speed. The pitch of the spiral blades 421 in the middle is 5cm to 10cm, which reduces the forward distance of the nut, allowing it to remain in the spiral cylinder 42 for a longer time, thus ensuring thorough mixing of the nut and the cleaning agent.

[0035] Reference Figure 2 , Figure 3A limit switch 45 is fixedly connected to one side of the guide plate 44, and a pump 46 electrically connected to the limit switch 45 is fixedly connected to the inner wall of one side of the cabinet 41. A storage tank 47 connected to the inlet of the pump 46 is installed on the outer side of the cabinet 41. A circulation pipe 471 is fixedly connected to one side of the storage tank 47, and a collection box 6 is fixedly connected to one end of the circulation pipe 471. The collection box 6 is located below the filter box 5 and is used to collect the cleaning agent dripping from the through hole of the filter box 5. The cleaning agent then flows into the storage tank 47 through the circulation pipe 471, completing the recycling of the cleaning agent and reducing the consumption of the cleaning agent. A movable nozzle 461 is fixedly connected to one end of the outlet of the pump 46. The movable nozzle 461 is used to spray the cleaning agent into the spiral cylinder 42 and mix it with the nut. The contact of the limit switch 45 is located on one side of the upper end of the baffle 441. When the baffle 441 rotates, it can contact the contact of the limit switch 45, thereby controlling the limit switch 45 to send a command to the pump 46, causing the pump 46 to operate and spray the cleaning agent from the movable nozzle 461 into the spiral drum 42. When the baffle 441 is in the closed state and is not in contact with the contact of the limit switch 45, the pump 46 will not operate.

[0036] refer to Figure 2 , Figure 7 and Figure 8 Both the first cleaning cabinet 11 and the second cleaning cabinet 12 include a body 13, a filter cartridge 14 fixedly installed inside the body 13, and a stirring blade 15 rotatably connected inside the filter cartridge 14. The feed inlet of the filter cartridge 14 is fixedly connected to the upper end of the body 13 and is located directly below the discharge port of the feeding device 2, ensuring that the nut can stably enter the filter cartridge 14. A drive box 16 for driving the stirring blade 15 to rotate is installed on one side of the body 13. The drive box 16 contains a motor, gears, a chain, and a transmission rod. The transmission rod is fixedly connected to one end of the stirring blade 15. This driving method is existing technology and will not be described in detail here. The drive box 16 is used to drive the stirring blade 15 to rotate back and forth inside the filter cartridge, and to complete the rotation of the nut through the stirring blade, thereby improving the cleaning effect. A port 141 communicating with the discharge port of the body 13 is opened on one side of the filter cartridge 14. When the stirring blade 15 rotates, it can push some of the cleaned nuts out of the port 141 and slide onto the upper side of the vibrating plate 32 through the discharge port of the machine body 13.

[0037] refer to Figure 2 , Figure 7 and Figure 8A spray pipe 17, with one end penetrating the inner wall of a filter cartridge 14, is fixedly connected to one side of the machine body 13. Multiple high-pressure nozzles arranged in an array are fixedly connected to the lower side of the spray pipe 17 for cleaning oil and impurities from the surface of the nuts. A circulating water tank 18 is fixedly connected to one side of both the first cleaning cabinet 11 and the second cleaning cabinet 12. A high-pressure pump 19, which is fixedly connected to one end of the spray pipe 17, is fixedly connected to the upper end of each of the two circulating water tanks 18. The high-pressure pump 19 is used to draw water from inside the circulating water tanks 18, increasing the pressure and flow rate of the water jet, thereby enhancing the cleaning effect on the nuts. Furthermore, the lower end of the circulating water tank 18 is connected to the lower end of the machine body 13, allowing the water used for cleaning the nuts to be recycled, reducing water consumption.

[0038] Reference Figure 3 , Figure 5 A drive mechanism 43 is fixedly connected to the inner wall of the cabinet 41. The drive mechanism 43 is used to drive the spiral cylinder 42 to rotate stably inside the cabinet 41, thereby completing the conveying and mixing of nuts. In this application, the drive mechanism 43 consists of a motor, transmission gears, a gear ring, rollers, and a positioning ring. This drive mechanism 43 is prior art and will not be described in detail here.

[0039] Reference Figure 3 , Figure 4 and Figure 5 A guide plate 44 is fixedly connected to one end of the cabinet 41 near the impurity removal device 3 to guide the nut into the screw cylinder 42. One end of the discharge port of the impurity removal device 3 extends into the inside of the guide plate 44 to ensure the nut falls stably onto it. One end of the screw cylinder 42 is rotatably connected to the inside of the guide plate 44 to prevent the nut from falling out when it slides into the screw cylinder 42. A baffle 441 is hinged to one side of the guide plate 44 to control the amount of nut conveyed, reducing nut accumulation during conveying and ensuring stable nut conveying. An elastic pad 442 is fixedly connected to one side of the baffle 441 to reduce collisions between the nut and the baffle 441, improving the service life of the baffle 441. The lower ends of both the elastic pad 442 and the baffle 441 are arc-shaped, reducing damage to the nut and preventing scratches as it passes under the baffle 441, thus ensuring the quality of the nut.

[0040] The implementation principle of the fully automatic nut cleaning device in this application embodiment is as follows: First, the first feeding device 2 transports the freshly produced nuts to the filter cartridge 14 inside the first cleaning cabinet 11. The high-pressure pump 19 is activated to draw water from the circulating water tank 18, which is then sprayed out by the high-pressure nozzle of the spray pipe 17 to perform preliminary cleaning of the nuts. Second, the drive box 16 inside the first cleaning cabinet 11 is activated to drive the stirring blades 15 to rotate, moving the cleaned nuts to the outlet 141, where they slide from the discharge port of the machine body 13 onto the vibrating plate 32. Third, the vibration motor 33 is activated, causing the vibrating plate 32 to vibrate along the damping rod 34 and the upper side of the vibration spring 35, effectively cleaning any remaining impurities or liquid on the nut surface. Fourth, the nuts, after vibration treatment, slide from the guide plate 44 into the spiral cylinder 42 of the mixing device 4, and during the sliding process on the guide plate 44… The nut will push the lower end of the baffle 441 to rotate. At this time, the upper end of the baffle 441 will contact the contact of the limit switch 45, controlling the pump 46 to operate, so that the cleaning agent can be sprayed from the movable nozzle 461 into the spiral cylinder 42 to mix with the nut. In the fifth step, the drive mechanism 43 inside the cabinet 41 is started to drive the spiral cylinder 42 to rotate. The spiral blades 421 inside the spiral cylinder 42 push the nut and cleaning agent forward. The nut will roll during the forward movement, fully mixing with the cleaning agent, until the nut is discharged from the other end of the spiral cylinder 42 and falls into the filter box 5. In the sixth step, the second feeding device 2 is started to transport the nut inside the filter box 5 to the second cleaning cabinet 12. The above operation is repeated to complete the secondary cleaning of the nut and transport it to the vibration device 7. Finally, the vibration device 7 is started to remove the liquid on the surface of the nut, and then the nut falls into the collection box 8 to complete the cleaning of the nut.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
