DETAILED DESCRIPTION

[0036] The utility model makes further detailed explanation in combination with example.

[0037] Example 1

[0038] As Figure 1 , Figure 3 and Figure 7 shown, the utility model provides a fish slice rolling and rubbing machine of rolling and rubbing part self-cleaning, including fixed frame 1, the top rotationally connected of fixed frame 1 has outer cylinder 2, and one end of outer cylinder 2 is connected with external motor, and the inner wall of outer cylinder 2 is provided with inner cylinder 8, and the inner wall of inner cylinder 8 is provided with honeycomb type protruding piece, and the front end of outer cylinder 2 is detachably connected with cylinder cover 3, and the outer wall of inner cylinder 8 is fixedly connected with gear ring 9, and gear ring 9 and the inner wall of outer cylinder 2 are engagedly connected, and the top of outer cylinder 2 is provided with pre-washing subassembly, and pre-washing subassembly is used for pre-washing the surimi remaining in the inner wall of outer cylinder 2, and pre-washing subassembly includes high-pressure jet 21 fixedly connected at the top of outer cylinder 2, and the inner wall of inner cylinder 8 is provided with cleaning subassembly, and cleaning subassembly is used for eliminating the oil dirt of the inner wall of inner cylinder 8.

[0039] In the embodiment, the inner wall of inner cylinder 8 is provided with honeycomb type protrusion, which increases the collision frequency of fish slice and curing material, forms directional guide groove by the protrusion texture, generates vortex along the texture direction when washing, reduces surface adsorption, improves washing effect, when needing to wash, the outer cylinder 2 starts to rotate, and drives inner cylinder 8 to rotate under the action of gear ring 9, uses centrifugal force to cooperate with honeycomb protrusion to throw out the surimi remaining in the inner wall, sprays fan-shaped water body to the inner wall of inner cylinder 8 by high-pressure jet 21, realizes the preliminary cleaning of the inner wall of inner cylinder 8, and the inner wall of inner cylinder 8 is cleaned twice by cleaning subassembly, improves the cleaning effect of the inner wall of inner cylinder 8.

[0040] Example 2

[0041] As Figure 1 , Figure 4 and Figure 9As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the cleaning component includes a water storage tank 4 fixedly connected to the bottom of the fixing frame 1, a heating pipe 23 fixedly connected inside the water storage tank 4, a high-pressure nozzle 21 connected to the water storage tank 4 through a pipe, a paddle 10 rotatably connected to the inner wall of the inner cylinder 8, and a plurality of steam nozzles 13 slidably connected to the top of the paddle 10.

[0042] During the marinating process, fish fillet fragments, seasonings, and oil adhere to the inner wall of the inner cylinder 8. Rinsing with water can only remove some of the fish fillet fragments, leaving the oil and other components on the inner wall of the inner cylinder 8. This results in a slippery oil film forming on the inner wall of the inner cylinder 8, which affects the quality of subsequent marinating and processing of the fish fillets.

[0043] In this embodiment, the water inside the water storage tank 4 is heated by the heating pipe 23. During the cleaning process, high-temperature atomized steam can be sprayed onto the inner wall of the inner cylinder 8 through the steam nozzle 13 to melt the solidified grease. Combined with the centrifugal force generated by the rotation of the inner cylinder 8, the liquid grease is thrown out, which increases the cleaning effect on the inner wall of the inner cylinder 8, reduces the adsorption of grease, and thus increases the self-cleaning effect of the equipment. The equipment is also sterilized by using high temperature.

[0044] Example 3

[0045] like Figure 4 and Figure 5 As shown, based on Embodiment 2, this utility model provides a technical solution: Preferably, a plurality of baffle plates 12 are fixedly connected to the top of the blade 10, and weakening grooves are provided on both sides of the baffle plates 12. The bottom of the baffle plates 12 is slidably connected to the steam nozzle 13. The bottom of the steam nozzle 13 is fixedly connected to a fixing plate 16. A plurality of fixing rods 18 are fixedly connected to the bottom of the fixing plate 16. A spring 19 is sleeved on the outer wall of the fixing rod 18. A conveying pipe 17 is fixedly connected to the bottom of the steam nozzle 13. A limiting rod 14 is slidably connected to the top of the fixing plate 16. The limiting rod 14 is slidably connected to the blade 10. A cleaning cloth 11 is slidably connected to both sides of the blade 10. A scraper 15 is fixedly connected to the side of the cleaning cloth 11 near the inner wall of the inner cylinder 8. The scraper 15 is made of shape memory alloy.

[0046] Since the steam nozzle 13 is located on the top of the blade 10, it is easier to spray the atomized high-temperature steam over a wider range. The blade 10 needs to rotate when marinating fish fillets. The steam nozzle 13 is exposed during the marinating process and is prone to damage, which increases the cost of maintenance.

[0047] In the embodiment, the blocking plate 12 is arranged in an inclined manner, and the top of the blocking plate 12 covers the top of the steam nozzle 13 to prevent the steam nozzle 13 from contacting the fish slices. Specifically, when the steam nozzle 13 is used for cleaning, the limiting rod 14 at the front end of the paddle 10 is removed, the steam nozzle 13 is popped up at the bottom under the action of the fixing rod 18 and the spring 19, and the blocking plate 12 is offset to the two sides under the action of the weakened grooves at the two sides of the blocking plate 12. The steam nozzle 13 is protected under the action of the structure, and the service life of the steam nozzle 13 is prolonged.

[0048] It should be noted that the inner cylinder 8 is heated by the steam nozzle 13, and at this time, the scraper 15 expands to increase the friction effect with the inner wall, and further increase the cleaning effect on the inner wall of the inner cylinder 8.

[0049] As shown in Figure 1 and Figure 2 Preferably, the front end of the fixed frame 1 is fixedly connected with a limiting frame 6, the top of the limiting frame 6 is rotatably connected with a cleaning rod 7, and the cleaning rod 7 is slidably connected with the cylinder cover 3.

[0050] During the process of taking out the fish slices after the device is used for marinating the fish slices, the material port is left with marinating materials, and the staff needs to flush and wipe the material port, which increases the workload and reduces the cleaning efficiency.

[0051] In the embodiment, the cleaning rod 7 is arranged at the front end of the cylinder cover 3 under the action of the inner cylinder 8, so that the outlet of the cylinder cover 3 can be cleaned while the outer cylinder 2 rotates, automatic cleaning is realized, and the workload is reduced.

[0052] As shown in Figure 8 Preferably, the top of the fixed frame 1 is fixedly connected with a recovery box 5, the recovery box 5 is connected with the fixed frame 1 through a pipeline, and a filter screen 22 is slidably connected to the inner side wall of the recovery box 5.

[0053] Because the sewage after cleaning contains fish meat scraps and other components, direct discharge of the water body will cause blockage of the pipeline and pollution of water resources.

[0054] In the embodiment, the filter screen 22 is made of flexible material and can filter solid blocks in the water body. The staff can regularly remove the filter screen 22 to remove the upper debris, so that the phenomenon of blockage of the pipeline is avoided.

[0055] As shown in Figure 7 Preferably, the top of the outer cylinder 2 is fixedly connected with a disinfection lamp 20.

[0056] In the embodiment, the disinfection lamp 20 is arranged to automatically irradiate for fifteen minutes after cleaning is completed, so as to damage the DNA of microorganisms and improve the sterilization rate.

[0057] The working principle of this self-cleaning fish fillet tumbler is explained in detail below.

[0058] like Figures 1-9 As shown, when cleaning is required, the outer cylinder 2 starts to rotate, and under the action of the gear ring 9, it drives the inner cylinder 8 to rotate. Centrifugal force, combined with honeycomb protrusions, throws out the fish paste remaining on the inner wall. High-pressure nozzles 21 spray fan-shaped water onto the inner wall of the inner cylinder 8 for rinsing, achieving initial cleaning of the inner wall. The inner wall of the inner cylinder 8 has honeycomb-shaped protrusions, which increase the collision frequency between the fish fillets and the marinade. The textured surface forms a directional flow channel, causing the water to swirl along the texture during cleaning, reducing surface adsorption. Then, heating pipes 23 heat the water inside the water tank 4. During the cleaning process, high-temperature atomized steam is sprayed onto the inner wall of the inner cylinder 8 through steam nozzles 13, melting the solidified grease. Combined with the centrifugal force generated by the rotation of the inner cylinder 8, the liquid grease is thrown out, increasing the cleaning effect on the inner wall of the inner cylinder 8, reducing grease adsorption, and thus increasing the cleaning efficiency. The system features a self-cleaning effect and utilizes high temperature for sterilization. The baffle plate 12 is inclined, with its top covering the top of the steam nozzle 13, preventing contact between the steam nozzle 13 and the fish fillets. When the steam nozzle 13 is to be used for cleaning, the limiting rod 14 at the front end of the paddle 10 is removed. At this time, the steam nozzle 13 pops upward under the action of its bottom fixing rod 18 and spring 19, and the baffle plate 12 shifts to both sides under the action of its two side weakening grooves. The inner cylinder 8 experiences an increase in internal temperature under the action of the steam nozzle 13. At this time, the scraper 15 expands, increasing the friction effect with the inner wall and further enhancing the cleaning effect on the inner wall of the inner cylinder 8. The cleaning rod 7 is located at the front end of the cylinder cover 3 under the action of the inner cylinder 8, and can clean the outlet of the cylinder cover 3 while the outer cylinder 2 rotates. Finally, the sterilization lamp 20 automatically irradiates for fifteen minutes after cleaning to destroy the DNA of microorganisms and improve the sterilization rate.

[0059] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
