Description

Technical Field

[0001] The invention relates to the technical field of apple cleaning, and in particular to an apple surface cleaning device. Background Art

[0002] In the process of fruit processing and production, the fruit needs to be cleaned, especially apples, which can be eaten directly. Apples are spherical in shape, sweet in taste, and crisp in taste. Apples are a low-calorie food, producing only 60 kcal of calories per 100 grams of apples. Apples are rich in iron, copper, iodine, manganese, zinc and other elements, and the nutrients in apples are highly soluble and easily absorbed by the human body. Therefore, apples are loved by most people. Apples can be eaten raw, juiced, or processed into other foods such as preserved fruits for human consumption. When apples are just picked, there is still a lot of dirt and residual pesticides on the surface. Therefore, apples usually need to be cleaned before processing. After cleaning, the moisture attached to the apples should be wiped dry to wait for the next step. At present, the apple cleaning equipment mainly includes bubble cleaning machines and flat roller cleaning machines. The apples are first placed in the interior of the bubble cleaning machine for preliminary cleaning, and then transported to the interior of the flat roller cleaning machine through a conveying device, and the apples are cleaned twice by the rollers inside.

[0003] When the apples are cleaned a second time by the flat roller cleaning machine, since the flat roller cleaning machine is provided with multiple groups of rollers, the surfaces of these rollers are covered with bristles for cleaning the surfaces of the apples, and there are gaps between the multiple rollers, when the apples are cleaned by the rollers, the apples will be located inside the gaps, so that the surfaces of the apples will be cleaned by the bristles of the apples.

[0035] The following will refer to the attached Figures 1 to 8 The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0036] Embodiment 1

[0037] Since the flat roller cleaning machine 11 is provided with multiple groups of rollers, the surfaces of these rollers are covered with bristles for cleaning the surface of the apples, and there are gaps between the multiple rollers. When the apples are cleaned by the rollers, the apples will be located inside the gaps, so that the surface of the apples will be cleaned by the bristles of the apples. However, due to the shape of the apples and the wear of the bristles, the apples will continue to flip inside the gaps, making it impossible for the apples to move to the discharge end of the flat roller cleaning machine 11 for discharge.

[0038] As attached Figure 1-Figure 8 As shown, an apple surface cleaning device comprises:

[0039] The bubble cleaning machine 10 has a flat roller cleaning machine 11 installed on one side of the bubble cleaning machine 10. The bubble cleaning machine 10 cooperates with the flat roller cleaning machine 11 to clean apples.

[0040] The flat roller cleaning machine 11 is provided with a pushing assembly 20 for pushing the apples between two adjacent rollers on the flat roller cleaning machine 11, thereby preventing the apples from being stuck in the gap between the two adjacent rollers.

[0041] The pushing assembly 20 includes a driving source 21 installed on a side wall of the flat roller cleaning machine 11. The inner wall of the flat roller cleaning machine 11 is rotatably connected to two driving shafts 22, and the two driving shafts 22 are respectively located at the head and tail ends of the flat roller cleaning machine 11. The output end of the driving source 21 passes through the flat roller cleaning machine 11 and is connected to one end of the driving shaft 22, and the driving source 21 is located at the head end of the flat roller cleaning machine 11. Two transmission gears 23 are fixed on the surfaces of the two driving shafts 22, and a transmission belt 24 is installed between the two corresponding transmission gears 23 at the head and tail of the flat roller cleaning machine 11.

[0042] An end block 25 is fixed on one side of the two transmission belts 24, and an external connecting block 26 is fixed between the two end blocks 25. In this embodiment, the external connecting block 26 is in a U-shape, and the inner wall of the external connecting block 26 is slidably connected to a limiting end plate 27, and a sponge 28 is installed at the bottom of the limiting end plate 27.

[0043] The bubble cleaning machine 10 and the flat roller cleaning machine 11 are both prior art. The tail end of the bubble cleaning machine 10 is connected to the head end of the flat roller cleaning machine 11. The head end of the bubble cleaning machine 10 is used to pour apples to be cleaned, and the tail end of the bubble cleaning machine 10 is used to discharge the apples. The head end of the flat roller cleaning machine 11 is used to receive the apples cleaned by the bubble cleaning machine 10, and the tail end of the flat roller cleaning machine 11 is used to discharge the cleaned apples. When in use, the staff first pours the apples to be cleaned into the interior of the bubble cleaning machine 10 for preliminary cleaning. The apples after preliminary cleaning are transported to the tail end of the bubble cleaning machine 10 through the conveying device inside the bubble cleaning machine 10, and then fall to the head end of the flat roller cleaning machine 11.

[0044] The rollers on the flat roller cleaning machine 11 are in a rotating state, and there are gaps between the multiple rollers. The apples will be stuck in the gaps and cleaned by the bristles of the rollers. The bristles on the surface of the rollers are in contact with the surface of the apples to clean the surface of the apples. Due to the rotation of the rollers, the bristles produce friction on the surface of the apples. At the same time, the water spray system on the flat roller cleaning machine 11 sprays cleaning liquid on the apples and the bristles, thereby removing dirt, impurities, etc. on the surface of the apples.

[0045] The output end of the driving source 21 drives the driving shaft 22 at the front end of the flat roller cleaning machine 11 to rotate, and the driving shaft 22 at the front end of the flat roller cleaning machine 11 drives the driving shaft 22 at its rear end to rotate through the transmission belt 24. At this time, the two end blocks 25 drive the external connecting block 26 to slide along the sliding track of the transmission belt 24, and the external connecting block 26 pushes the apples inside the gap to the rear end of the flat roller cleaning machine 11 through the limiting end plate 27 and discharges them, thereby preventing the apples from being stuck inside the gap.

[0046] Through the cooperation of the driving source 21, the driving shaft 22, the transmission gear 23 and the transmission belt 24, the limiting end plate 27 on the external connecting block 26 can push the apples stuck in the gap to slide toward the tail end of the flat roller cleaning machine 11 for discharge, thereby preventing the apples from being stuck in the gap continuously and causing blockage, thereby reducing the cleaning efficiency of the flat roller cleaning machine 11.

[0047] Embodiment 2

[0048] When the limiting end plate 27 pushes the apples inside the gap, the apples contacted by the limiting end plate 27 will move against the apples behind them, and when the apples are pushed by the limiting end plate 27, the apples will be accelerated to leave the flat hair roller cleaning machine 11, which can easily cause low apple cleaning efficiency, and when the limiting end plate 27 continues to push the apples, the apples will be squeezed and stacked, which will make the hair roller unable to clean some apples. In view of this, improvements are made on the basis of Example 1.

[0049] Reference Figure 3-Figure 8 As shown, a lifting assembly 30 is provided on the limiting end plate 27, which is used to enable the limiting end plate 27 to push the apples inside the gap in stages, thereby preventing the apples from being continuously pushed, which causes low cleaning efficiency.

[0050] The lifting assembly 30 includes two limiting sliders 31 fixed on the side walls of the limiting end plate 27. The two limiting sliders 31 are symmetrical with the limiting end plate 27 as the center. The inner walls on both sides of the external connecting block 26 are provided with limiting grooves 32, and the limiting sliders 31 are slidably connected to the inside of the limiting grooves 32, which are used to limit the limiting end plate 27, thereby maintaining the stability of the limiting end plate 27 when sliding.

[0051] A first return spring 33 is fixed between the limit sliding block 31 and the limit sliding groove 32 for supporting the limit end plate 27 so as to facilitate the return of the limit end plate 27 .

[0052] An outer cylinder 34 is fixed on both sides of the limiting end plate 27, and an inner column 35 is slidably connected to the inner wall of the outer cylinder 34. A second reset spring 36 is fixed between one end of the inner column 35 and the inner wall of the outer cylinder 34 for supporting the inner column 35, thereby facilitating the reset of the inner column 35.

[0053] A connecting plate 37 is fixed to one side of the inner column 35, and a side plate 38 is fixed to the inner wall of the flat roller cleaning machine 11, and a guide rail 39 is installed on the side plate 38. The guide rail 39 has a first working surface 390, a second working surface 391, a third working surface 392 and a fourth working surface 393, and the first working surface 390, the second working surface 391, the third working surface 392 and the fourth working surface 393 are connected, the first working surface 390 and the third working surface 392 are both oblique, the second working surface 391 and the fourth working surface 393 are both straight, the top end of the first working surface 390 is connected to one end of the second working surface 391, the other end of the second working surface 391 is connected to the top end of the third working surface 392, the bottom end of the third working surface 392 is connected to one end of the fourth working surface 393, and the other end of the fourth working surface 393 is connected to the bottom end of the first working surface 390 located behind it.

[0054] When the transmission belt 24 drives the limiting end plate 27 on the external connecting block 26 to slide, the connecting plate 37 of the external connecting block 26 will first contact the first working surface 390, and the connecting plate 37 will move upward along the inclined surface of the first working surface 390, and the connecting plate 37 drives the limiting end plate 27 to move upward inside the external connecting block 26 through the outer tube 34 and the inner column 35, and the limiting slider 31 of the limiting end plate 27 will compress the first return spring 33 above it and pull the first return spring 33 below it.

[0055] Since the distance between the first working surface 390 and the third working surface 392 corresponds to a gap, and the width of the fourth working surface 393 also corresponds to a gap, when the connecting plate 37 slides from the first working surface 390 to the third working surface 392, the limiting end plate 27 moves up and crosses the gap below. At this time, the apples in the gap below are not pushed by the limiting end plate 27, so that they can be cleaned by the hair roller. When the connecting plate 37 slides from the third working surface 392 to the fourth working surface 393, the limiting end plate 27 moves down to the top of the hair roller, and the connecting plate 37 When sliding from the fourth working surface 393 to the first working surface 390, the limiting end plate 27 will push the apples in the corresponding gap to slide into the next gap, and the contact between the apples will cause the apples to flow into the next gap. When the connecting plate 37 slides to the first working surface 390, it will move up again, thereby passing over the apples that have been pushed, thereby preventing the apples from being pushed continuously. When the connecting plate 37 slides along the guide rail 39, the above action will be repeated, so that the limiting end plate 27 can push the apples inside the gap in stages, thereby keeping the hair roller clean on the apples.

[0056] Reference Figure 3-Figure 8 As shown, a cleaning assembly 40 is provided on the limiting end plate 27, which is used to clean the area of ​​the apple contacting the limiting end plate 27 when the limiting end plate 27 pushes the apple, thereby improving the cleaning efficiency of the apple.

[0057] The cleaning component 40 includes a plurality of equidistantly arranged linkage blocks 41 fixed on the guide rail 39, wherein the distances between any two of the plurality of linkage blocks 41 are equal, and one side of the linkage blocks 41 has an arcuate surface, and each linkage block 41 is respectively located on the corresponding first working surface 390, and an opening 42 is provided on the limiting end plate 27, and the inner bottom wall of the opening 42 is rotatably connected to a plurality of equidistantly arranged rotating shafts 43, and a cleaning brush 44 is provided on the plurality of rotating shafts 43 for cleaning the apples, thereby improving the cleaning efficiency of the apples.

[0058] A plurality of equidistantly arranged receiving grooves 45 are provided on the limiting end plate 27, and the number of the receiving grooves 45 is the same as the number of the rotating shafts 43. In the present embodiment, the receiving grooves 45 are circular, and the inner walls of the plurality of receiving grooves 45 are rotatably connected to the rotating shafts 46, and linkage gears 47 are fixed to the tops of the plurality of rotating shafts 46. A linkage rack 410 is slidably connected to the inner wall of the limiting end plate 27, and the linkage rack 410 is meshedly connected to the linkage gear 47.

[0059] A push column 411 is fixed on one side of the connecting plate 37 facing the limiting end plate 27, and accommodating holes are provided on both sides of the limiting end plate 27, and the push column 411 is slidably connected inside the accommodating hole, and a limiting groove 412 is provided on one side of the linkage rack 410, one of the push columns 411 is fixed on a side wall of the linkage rack 410, and the other push column 411 is slidably connected inside the limiting groove 412.

[0060] Since the upper end of the limiting end plate 27 has a cavity, and the linkage gear 47 and the linkage rack 410 are both located inside the cavity, and the width of the linkage rack 410 is smaller than the width of the cavity, when the connecting plate 37 slides on the guide rail 39, the connecting plate 37 will first contact the arc surface of the linkage block 41, and the linkage block 41 will push the connecting plate 37 to slide toward the limiting end plate 27. At this time, the inner column 35 slides toward the inside of the outer cylinder 34 to compress the second return spring 36. The pushing column 411 fixed to the linkage rack 410 will drive the linkage rack 410 to slide inside the limiting end plate 27, and the other pushing column 411 will slide inside the limiting groove 412. At this time, the linkage rack 410 will drive the linkage gear 47 to rotate, and the linkage gear 47 drives the rotating shaft 43 to rotate through the rotating shaft 46, so that the cleaning brush 44 cleans the apples.

[0061] When the connecting plate 37 is separated from the linkage block 41, the second reset spring 36 drives the inner column 35 to reset, and the connecting plate 37 drives the linkage rack 410 to slide and reset through the pushing column 411, and the linkage rack 410 drives the rotating shaft 46 to rotate again through the linkage gear 47, so that the cleaning brush 44 of the rotating shaft 43 cleans the surface of the apple again.

[0062] When the connecting plate 37 slides on the guide rail 39, the connecting plate 37 can drive the limiting end plate 27 to slide up and down through the outer cylinder 34 and the inner column 35, thereby pushing the apples inside the flat roller cleaning machine 11 in stages, so that the apples can be evenly cleaned by the roller when sliding from the head end of the flat roller cleaning machine 11 to the tail end thereof.

[0063] The connecting plate 37 contacts the linkage block 41, and the connecting plate 37 drives the linkage rack 410 to slide through the pushing column 411. The linkage rack 410 drives the rotating shaft 46 to rotate through the linkage gear 47, and the rotating shaft 46 drives the rotating shaft 43 to rotate, so that the cleaning brush 44 cleans the apples when being pushed, thereby improving the cleaning efficiency of the apples.

[0064] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
