[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figures 1 to 5As shown, the present invention provides a technical solution of a raisin oiling device: it includes a support base 1 and a drum 2, the upper surface of the support base 1 is rotatably provided with a drum 2 through a support block and a support ring, the drum 2 is provided with a feed port 21 for feeding raisins, and a sealing plug is provided at the feed port 21, the drum 2 is provided with an oil brushing and evacuating mechanism 4 for brushing oil and evacuating the raisins, the drum 2 and the oil brushing and evacuating mechanism 4 are driven to rotate by a power mechanism 3, and a discharge and collecting mechanism 5 is provided below the drum 2, and the discharge and collecting mechanism 5 is used to discharge the raisins after adding oil from the drum 2; the present invention is designed, therefore, the present invention is designed, when it is necessary to add oil to the raisins, the processing personnel first open the sealing plug of the feed port 21 on the drum 2, and then feed the raisins into the drum 2, and then seal the sealing plug to the feed port 21, and then control the power mechanism 3 to discharge the raisins. The making drum 2 rotates on the support seat 1 through the cooperation of the support block and the support ring. At the same time, the power mechanism 3 can drive the oil brushing and evacuation mechanism 4 to rotate in the opposite direction in the drum 2. Then, the oil brushing and evacuation mechanism 4 can rotate to apply the oil to be added to the surface of the raisins rolling in the drum 2, thereby realizing the smearing and adding of oil to the raisins rolling in the drum 2. Since the oil is not directly injected into the drum 2, it will not cause a large amount of oil waste, and it will not cause oil accumulation at the bottom of the drum 2. When the raisins are smeared with oil in the drum 2, the rotation of the drum 2 is stopped, so that the discharge and collection mechanism 5 is located below the drum 2, and then the discharge and collection mechanism 5 is opened to facilitate the rapid discharge and collection of the raisins with oil added in the drum 2, and then the discharge and collection mechanism 5 is closed below the drum 2, so that the drum 2 can continue to add oil to the raisins.

[0023] As an embodiment of the present invention, the power mechanism 3 includes a support frame 31, a driving gear 32, a gear plate 33, a driving shaft 34, a driving wheel 35, a rotating ring 36, a connecting shaft 37, a driven wheel 38 and a driving belt 39;

[0024] A support frame 31 is fixed to an upper surface of one side of the support base 1, and the support frame 31 is used to fix and support the drive motor;

[0025] A driving gear 32, the output shaft of the driving motor is sleeved with the driving gear 32 via a driving shaft 34;

[0026] The gear plate 33 is fixed to the outer ring surface of the left end face of the drum 2, and the teeth of the outer ring surface of the gear plate 33 mesh with the teeth of the driving gear 32;

[0027] A driving wheel 35, which is sleeved on a driving shaft 34 extending from the left side of the driving gear 32;

[0028] A rotating ring 36 is rotatably mounted on the left and right end caps of the drum 2, and a connecting shaft 37 is inserted into the rotating ring 36 on the left end cap, and the connecting shaft 37 is connected to the oil brushing and evacuation mechanism 4;

[0029] The driven wheel 38 and the driving belt 39 are respectively sleeved on the connecting shaft 37 and connected to the driving wheel 35 through the driving belt 39; according to the design of the present invention, when the drum 2 needs to rotate, the processing personnel controls the driving motor through the control box on the side of the support seat 1, and the output shaft of the driving motor drives the drum 2 to rotate through the driving gear 32 and the meshing gear plate 33, and at this time the driving wheel 35 on the left side of the driving gear 32 drives the driven wheel 38 to rotate through the driving belt 39, and since the connecting shaft 37 is rotatably connected to the end cover of the left end face of the drum 2 through the rotating ring 36, the connecting shaft 37 drives the oil brushing and evacuation mechanism 4 to rotate in the opposite direction to the drum 2 in the drum 2, so that the oil brushing and evacuation mechanism 4 can not only rotate and apply oil to the raisins rolling in the drum 2, but also rotate and disperse the raisins that are stuck to each other, thereby improving the uniformity of oil addition to the raisins.

[0030] As an embodiment of the present invention, the oil brushing and evacuation mechanism 4 includes an oil pipe shaft 41, a plug-in block 42, an oil injection main pipe 43, an oil distribution pipe 44, a guide strip 45 and an oil-draining tooth pipe 46;

[0031] The oil pipe shaft 41, the end cover on the right end face is detachably mounted on the drum 2 by bolts, and the oil pipe shaft 41 is plugged into the rotating ring 36 on the end cover on the right end, and the left end face of the oil pipe shaft 41 is inserted into the drum 2;

[0032] A plug-in block 42 is fixed to the left end face of the oil pipe shaft 41, and a plug-in square hole 371 is opened on the right end face of the connecting shaft 37, and the plug-in block 42 is slidably inserted into the plug-in square hole 371;

[0033] An oil injection manifold 43 rotatably disposed on the right end surface of the oil pipe shaft 41 via a rotating ring 36 ;

[0034] The oil distribution pipes 44 are connected to a plurality of groups of oil pipes 44 in a circumferential array on the outer ring surface of the oil pipe shaft 41, and each group of oil pipes 44 is provided with at least three;

[0035] The guide strips 45 are arranged in a circumferential array on the outer ring surface of the oil pipe shaft 41 with a plurality of guide strips 45 having a cavity structure, and each guide strip 45 having a cavity structure is supported and connected by a group of multiple oil distribution pipes 44;

[0036] The oil-repellent tooth tube 46 is fixed on the outer side of each guide strip 45, and the upper tube openings of the plurality of oil-repellent tooth tubes 46 are connected to the guide strip 45 of the cavity structure. The outer ring surface of each oil-repellent tooth tube 46 is provided with a plurality of oil seepage holes 461 in a circumferential array. When the oil needs to be applied to the raisins, the end cover with the oil pipe shaft 41, the plug-in block 42 and the plurality of oil-repellent tooth tubes 46 is inserted into the drum 2, so that the plug-in block 42 is inserted into the plug-in block 42 opened on the connecting shaft 37. The oil pipe is connected to the square hole 371, and then the end cover on the right is fixed to the drum 2 by bolts. The processing personnel connect the oil delivery pipe to the oil filling main pipe 43 through the oil pump. At this time, the oil delivery pipe will inject a certain proportion of oil into the oil pipe shaft 41 through the oil filling main pipe 43, and then inject the oil in the oil pipe shaft 41 into the guide strip 45 through the multi-component oil pipe 44. The oil in the guide strip 45 will enter the multiple oil-draining tooth tubes 46. Since the multiple oil-draining tooth tubes 46 are provided with multiple oil seepage holes 461, the oil seepage holes 461 will seep into the oil pipe shaft 41. The oil will drip onto the surface of the oil-repellent tooth tubes 46. Therefore, when the connecting shaft 37 drives the oil pipe shaft 41 to rotate through the plug-in block 42, the multiple groups of oil-repellent tooth tubes 46 will rotate in the opposite direction in the drum 2 to contact the raisins turned over in the drum 2, and can also play a role in evacuating the raisins in the drum 2. When the raisins pass through two adjacent oil-repellent tooth tubes 46, the oil dripping from the surface of the oil-repellent tooth tubes 46 will contact the raisins, and the oil will be added to the raisins in a scraping and smearing manner. The oil seepage holes 461 opened on the tooth tube 46 are small, so as not to cause a large amount of oil to be wasted, and can also play the role of evacuating and smearing the oil on the raisins rolling in the drum 2; and when it is necessary to clean the impurities adhering to the surface of the oil-repellent tooth tube 46, the driving motor stops rotating, so that the drum 2 and the oil pipe shaft 41 will stop rotating, and then the end cover bolts on the right side of the drum 2 are removed, and then the extended oil pipe shaft 41 is pulled to drive the multiple oil-repellent tooth tubes 46 to be pulled out from the drum 2 for cleaning or replacement.

[0037] As an embodiment of the present invention, the oil brushing and evacuation mechanism 4 further includes a sponge column 47. The outer ring surface of each of the oil-repelling tooth tubes 46 is sleeved with a sponge column 47, and the end of each oil-repelling tooth tube 46 is in contact with the inner ring surface of the drum 2. The present invention is designed to sleeve the sponge column 47 on the outer ring surface of the oil delivery pipe, so that the oil falling on the outer ring surface of the oil-repelling tooth tube 46 will penetrate into the sponge column 47, thereby preventing the oil from excessively dripping onto the inner wall of the drum 2 through the oil seepage hole 461, thereby reducing the generation of oil in the drum 2. At the same time, multiple sponge columns 47 rotate in the drum 2 and come into contact with the rolling raisins, which can evenly spread the oil that has seeped into the sponge columns 47 on the raisins, thereby improving the effect of grease coating on the raisins, and the end of the oleophobic tooth tube 46 is in contact with the inner ring surface of the drum 2, so that the oleophobic tooth tube 46 can scrape and clean the raisins that are adhered to the surface of the drum 2 due to the grease when rotating, thereby preventing the raisins that come into contact with the inner wall of the drum 2 from adhering to the inner wall of the drum 2 due to excessive accumulation.

[0038] As an embodiment of the present invention, the discharge collection mechanism 5 includes an arc-shaped sealing plate 51, a sliding insert 52, a pulling block 53 and a collection box 54. The outer ring surface of the bottom of the drum 2 is provided with a guide groove 22 along its length direction, and the guide groove 22 is provided with support grooves 23 on both sides along its length direction. The bottom of the support ring is provided with a notch groove, and the notch groove corresponds to the guide groove 22. The right end surface of the guide groove 22 is open, and the arc-shaped sealing plate 51 is slidably inserted in the guide groove 22. The two sides of the arc-shaped sealing plate are provided with support grooves 23 on both sides. A sliding insert 52 is fixed, and the symmetrical sliding insert 52 is squeezed and sealed into the support groove 23. A pulling block 53 is fixed to the right end face of the arc-shaped sealing plate 51. A collecting box 54 is placed on the upper surface of the support seat 1, and the upper surface opening of the collecting box 54 is aligned with the guide groove 22. According to the design of the present invention, when the raisins coated with oil need to be discharged from the drum 2, the guide groove 22 opened on the drum 2 is rotated to the bottom, and then the driving motor on the support frame 31 is stopped, so that the drum 2 and the multiple sets of oil-repellent tooth pipes are 46 stops rotating, and then the processing personnel clamps the pulling block 53 through the mechanical clamping claw or clamping device, and then continuously pulls the clamping block to the right, so that the arc-shaped sealing plate 51 is pulled out from the guide groove 22, and the sliding insert 52 is pulled out from the support groove 23, thereby facilitating the opening of the guide groove 22 below the drum 2, and then the raisins coated with oil in the drum 2 will fall into the collection box 54 placed on the upper surface of the support seat 1, thereby facilitating the collection of the raisins coated with oil. When the raisins in the drum 2 are completely discharged, The processing personnel insert the end face of the arc-shaped sealing plate 51 from the opening of the material guide groove 22, and the sliding insert 52 will be squeezed and inserted into the support groove 23. Then, when the arc-shaped sealing plate 51 is fully inserted into the material guide groove 22, the cooperation between the sliding insert 52 and the support groove 23 can support the arc-shaped sealing plate 51, preventing the arc-shaped sealing plate 51 from detaching from the material guide groove 22. At this time, the processing personnel can pull out the collection box 54 from the bottom of the drum 2, thereby facilitating the subsequent processing of the raisins collected in the collection box 54.

[0039] As an embodiment of the present invention, an oil suction chamber 511 is provided inside the arc-shaped sealing plate 51, and a plurality of oil suction holes 512 are provided on the upper cavity wall of the oil suction chamber 511, a sealing membrane 55 is slidably fitted on the upper cavity wall of the oil suction chamber 511, and an electromagnetic plate 56 is provided on the lower cavity wall of the oil suction chamber 511, a metal plate 57 is provided on the lower surface of the sealing membrane 55, and the metal plate 57 and the electromagnetic plate 56 are supported by a rubber spring 58, and the oil suction nozzle is fixed to the cavity wall of the right end face of the oil suction chamber 511; according to the design of the present invention, when the arc-shaped sealing plate 51 on the drum 2 rotates to the bottom and the raisins in the drum 2 need to be discharged, in order to avoid a small amount of dripping oil accumulating on the upper surface of the arc-shaped sealing plate 51 and being discharged into the collection box 54 along with the raisins, the processing personnel can energize the electromagnetic plate 56 to make it have magnetic adsorption force on the metal plate above The metal plate 57 is adsorbed, and then the sealing template will be separated from the upper cavity wall of the oil suction chamber 511 and slide downward under the drive of the metal plate 57. At this time, the rubber spring 58 located between the metal plate 57 and the electromagnetic plate 56 will be compressed, thereby facilitating the opening of the oil suction hole 512. The orifice diameter of the oil suction hole 512 is smaller than the size of a raisin, and the grease accumulated on the upper surface of the arc-shaped sealing plate 51 will drip into the oil suction chamber 511 through the oil suction hole 512, and then be extracted through the oil suction pipe connected to the oil suction nozzle on the right end face of the arc-shaped sealing plate 51. After the dripping grease is extracted, the electromagnetic plate 56 is powered off and loses its magnetism, and the elastic restoring force of the rubber spring 58 will push the sealing membrane plate 55 to slide upward and fit into the upper cavity wall of the oil suction chamber 511, thereby realizing the closure of multiple oil suction holes 512, preventing the oil falling into the oil suction chamber 511 from being discharged through the oil suction hole 512 when the drum 2 rotates.

[0040] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
