[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0044] The present invention provides a food processing conveyor device with a cleaning effect.

[0045] First embodiment:

[0046] Please refer to Figures 1 to 8 , a food processing conveyor device with a cleaning effect, including two conveyor frames 1, a conveying mechanism 2, a cleaning mechanism 3 and a cleaning mechanism 4;

[0047] The conveying mechanism 2 includes two conveying rollers 21 arranged inside the two conveyor frames 1. A conveyor belt 22 is sleeved on the surfaces of the two conveying rollers 21. A driving motor 23 is arranged on the left side of the back surface of the front conveyor frame 1. Transmission wheels 24 are fixedly provided at the front ends of the left conveying roller 21 and the output shaft of the driving motor 23. A transmission belt 25 is sleeved on the surfaces of the two transmission wheels 24. A protective cover 26 is fixedly provided on the left side of the front surface of the front conveyor frame 1. Protective plates 27 are fixedly provided on the opposite sides of the two conveyor frames 1 and on the top of the conveyor belt 22;

[0048] Please combine Figure 1 and Figure 2: Start the drive motor 23. The rotation of the drive motor 23 drives the bottom drive wheel 24 to rotate. The bottom drive wheel 24 drives the top drive wheel 24 to rotate through the transmission belt 25, thereby driving the left conveying roller 21 to rotate. The rotation of the conveying roller 21 drives the conveyor belt 22 to rotate, thus conveying the food to the right;

[0049] The cleaning mechanism 3 includes brackets 31 fixedly arranged at the bottoms of the two conveying frames 1. Two hydraulic rods 32 are fixedly arranged on the right side of the brackets 31. The output ends of the two hydraulic rods 32 are fixedly provided with an installation box 33. Two slide rails 34 are slidably connected to the inner side of the top of the installation box 33. The tops of the two slide rails 34 are respectively fixedly connected to the bottoms of the two conveying frames 1. A rotating rod 35 is longitudinally arranged inside the installation box 33. A moving wiping plate 36 is fixedly arranged at the top of the rotating rod 35. Both ends of the rotating rod 35 are rotatably connected with sliders 37. Slide frames 38 are fixedly arranged on the separated sides of the two conveying frames 1. The surfaces of the two sliders 37 are respectively slidably connected to the inner sides of the two slide frames 38. Springs 39 are fixedly arranged at the bottoms of the inner sides of the two slide frames 38. Gears 310 are fixedly arranged at both ends of the rotating rod 35 and on the opposite sides of the two slide frames 38. Gear plates 311 are fixedly arranged on the front and back of the installation box 33;

[0050] Please combine Figure 6 and Figure 7 : Start the two hydraulic rods 32. The two hydraulic rods 32 extend to the right and drive the installation box 33 to slide to the right on the surface of the slide rails 34. Through the setting of the guiding groove in the installation box 33, the rotating rod 35 drives the moving wiping plate 36 to move downward, and makes the two sliders 37 slide downward inside the slide frames 38, so that the moving wiping plate 36 is separated from the surface of the conveyor belt 22;

[0051] Furthermore, as the two hydraulic rods 32 continue to extend, they drive the installation box 33 to continue to move to the right. At this time, the two gears 310 will respectively contact the two gear plates 311. Through the rightward movement of the two gear plates 311, the two gears 310 drive the moving wiping plate 36 to rotate counterclockwise by 180 degrees through the rotating rod 35, so that the moving wiping plate 36 contacts the cleaning liquid at the bottom of the installation box 33;

[0052] The cleaning mechanism 4 includes an air knife 41 fixedly arranged on the inner wall of the installation box 33, a scraping plate 42 fixedly arranged on the inner side of the left side of the installation box 33, a rotating shaft 43 longitudinally rotatably connected to the inner side of the right side of the installation box 33. A cleaning brush 44 is fixedly arranged on the surface of the rotating shaft 43. A cleaning motor 45 for driving the rotating shaft 43 to rotate is arranged on the front of the installation box 33;

[0053] Please combine Figure 8: Start the cleaning motor 45. The rotation of the cleaning motor 45 drives the rotating shaft 43 and the cleaning brush 44 to rotate, thereby cleaning the food debris adhering to the surface of the conveyor belt 22. Through the setting of the scraper 42, the stubborn substances adhering to the surface of the conveyor belt 22 can be scraped off. The air knife 41 blows out gas to dry the conveyor belt 22, avoiding the contamination of food by residual moisture or cleaning liquid, and removing the food powder adhering to the surface.

[0054] Two guiding grooves are formed on the surface of the mounting box 33. When the mounting box 33 moves to the right, under the limitation of the guiding grooves, the rotating rod 35 drives the two sliders 37 to slide downward inside the two sliding frames 38. When the mounting box 33 continues to move to the right, the two gears 310 come into contact with the two gear plates 311, and the two gears 310 drive the rotating rod 35 and the moving cleaning plate 36 to rotate counterclockwise by 180 degrees.

[0055] A sliding groove matching with the two slide rails 34 is formed inside the top of the mounting box 33. The air knife 41 is externally connected with a blowing device, and a liquid inlet pipe is communicated with the surface of the mounting box 33.

[0056] In this embodiment, different from the existing food processing conveyor device, when this conveyor device conveys food, it can switch different cleaning modes according to the type of food. When conveying food with more processing powder or debris, the two hydraulic rods 32 extend to drive the mounting box 33 to move to the right, so that the moving cleaning plate 36 is separated from the conveyor belt 22, and the conveyor belt 22 is cleaned by using the air knife 41, the scraper 42 and the cleaning brush 44. When conveying sugary or gummy food, the hydraulic rod 32 extends to the right, so that the moving cleaning plate 36 dips into the cleaning liquid at the bottom of the mounting box 33. When the hydraulic rod 32 retracts, the moving cleaning plate 36 resets, and the conveyor belt 22 is cleaned by using the moving cleaning plate 36. After cleaning, the conveyor belt 22 is dried by the air knife 41. During the mode switching process, the cleaning mechanism 4 is always in a working state, which will not affect the normal conveying of food. Moreover, the device is modularly designed, easy to install, simple to maintain, and has a better combined cleaning effect.

[0057] Second Embodiment:

[0058] Please refer to Figure 1 、 Figures 9 to 11, on one side where the two conveying frames 1 are separated from each other, an adjusting mechanism 5 is fixedly installed. The adjusting mechanism 5 includes two mounting seats 51 fixedly installed on one side where the two conveying frames 1 are separated from each other. A sliding plate 52 is slidably connected to the inner side of each of the two mounting seats 51. The two ends of the right conveying roller 21 are rotatably connected to the inner sides of the two sliding plates 52. Electric telescopic rods 53 are fixedly installed on one side where the two mounting seats 51 are separated from each other. The output ends of the two electric telescopic rods 53 are respectively fixedly connected to the right sides of the two sliding plates 52;

[0059] Please combine with Figure 9 : Start the two electric telescopic rods 53. The two electric telescopic rods 53 retract to the left, thereby driving the two sliding plates 52 to slide to the left inside the two mounting seats 51 respectively. The movement of the two sliding plates 52 drives the right conveying roller 21 to move to the left, thereby canceling the tension state of the conveyor belt 22.

[0060] A supporting mechanism 6 is longitudinally rotatably connected to the inner sides of the two conveying frames 1. The supporting mechanism 6 includes a rotating shaft 61 longitudinally rotatably connected to the inner sides of the two conveying frames 1. A plurality of support frames 62 are fixedly installed on the right side of the rotating shaft 61. Passive gears 63 are fixedly installed at both ends of the rotating shaft 61. Driving toothed plates 64 are fixedly installed on the opposite sides of the two sliding plates 52. Support seats 65 are fixedly installed on the opposite sides of the two conveying frames 1. Protective seats 66 are fixedly installed on one side where the two conveying frames 1 are separated from each other;

[0061] Please combine with Figure 10 and Figure 11 : When the two sliding plates 52 move to the left, they will simultaneously drive the two driving toothed plates 64 to move to the left. When the two driving toothed plates 64 respectively come into contact with the two passive gears 63 and continue to move to the left, the two passive gears 63 are driven to rotate through the two driving toothed plates 64. The two passive gears 63 drive the support frames 62 to rotate counterclockwise through the rotating shaft 61, thereby supporting the conveyor belt 22.

[0062] Through grooves adapted to the right conveying roller 21 are respectively formed in the inner sides of the two conveying frames 1. Sliding grooves adapted to the two sliding plates 52 are respectively formed in the inner sides of the two mounting seats 51. A U-shaped groove adapted to the plurality of support frames 62 is formed in the inner side of the support seat 65.

[0063] In this embodiment, the two electric telescopic rods 53 retract to the left, so as to drive the right conveying roller 21 to move to the left by means of the two sliding plates 52. During the movement of the two sliding plates 52, the two driving tooth plates 64 are driven to move to the left at the same time, and then the rotating shaft 61 and the support frame 62 are driven to rotate counterclockwise through the two driven gears 63, so as to support the slack conveyor belt 22 upward, thus facilitating the deep cleaning of the conveyor belt 22 and the conveying roller 21, and avoiding the accumulation of food debris, dust, breeding of microorganisms or eggs in the gaps of the conveyor belt 22 or at the conveying roller 21, so as to prevent food contamination.

[0064] Third Embodiment:

[0065] Please refer to Figure 1 and Figure 12 On the top of the two conveying frames 1, a leveling mechanism 7 is fixedly installed. The leveling mechanism 7 includes adjusting seats 71 fixedly installed on the top of the two conveying frames 1. The inner sides of the two adjusting seats 71 are both threadedly connected with adjusting bolts 72. The bottom ends of the two adjusting bolts 72 are both fixedly provided with adjusting blocks 73. A leveling frame 74 is fixedly installed on the opposite sides of the two adjusting blocks 73;

[0066] Please combine Figure 12 : Rotate the two adjusting bolts 72 downward, so as to drive the two adjusting blocks 73 to slide downward inside the adjusting seats 71, and then adjust the leveling frame 74 downward, and use the leveling frame 74 to level the food, so as to avoid food accumulation and deformation of the lower-layer food under pressure;

[0067] Preferably, the position where the bottom of the leveling frame 74 contacts the food is made of food-grade silica gel material to avoid cracking of some brittle foods when leveling the food.

[0068] At the bottom on the right side of the two conveying frames 1, a collection box 8 is provided. On the left side of the inner wall of the collection box 8, a screening plate 9 is fixedly installed. On the bottom of the two conveying frames 1, support legs 10 are fixedly installed. The inner sides of the support legs 10 are threadedly connected with support feet 11;

[0069] Preferably, there are two chambers in the collection box 8. The left chamber is the collection place for food powder and debris, and the right chamber is the collection place for food. Through the threadedly connected support feet 11, the conveying device can be adjusted to a horizontal state on uneven ground, reducing the vibration or mechanical impact during the operation of the conveyor belt 22, and avoiding the edge breakage or fragmentation of brittle foods.

[0070] In this embodiment, by rotating the two adjusting bolts 72, the use height of the leveling frame 74 is adjusted by means of the two adjusting blocks 73. Through the setting of the leveling frame 74, the food on the conveyor belt 22 is prevented from accumulating too thickly, and the lower-layer food is deformed under pressure, resulting in adhesion of foods containing sugar or oil, making the screening plate 9 unable to effectively screen the food.

[0071] Please refer back again Figures 1 to 12 The working principle of the food processing conveyor device with cleaning effect provided by the present invention is as follows:

[0072] Step S1, by rotating two adjusting bolts 72, the use height of the leveling frame 74 is adjusted by means of two adjusting blocks 73. Under the action of the leveling frame 74, it is possible to prevent the food on the conveyor belt 22 from accumulating too thickly, and the food in the lower layer is deformed under pressure, resulting in adhesion of sugary or oily foods;

[0073] Start the drive motor 23. The drive motor 23 rotates to drive the bottom drive wheel 24 to rotate. The bottom drive wheel 24 drives the top drive wheel 24 to rotate through the drive belt 25, thereby driving the left conveyor roller 21 to rotate. The conveyor belt 22 is driven to rotate by the rotation of the conveyor roller 21, and the food is conveyed to the right;

[0074] Step S2, when conveying foods with a lot of powder and debris, start two hydraulic rods 32. The two hydraulic rods 32 extend to the right to drive the installation box 33 to slide to the right on the surface of the slide rail 34. Through the setting of the guide groove in the installation box 33, the rotating rod 35 drives the moving cleaning plate 36 to move downward, and the two sliders 37 slide downward inside the sliding frame 38, so that the moving cleaning plate 36 is separated from the surface of the conveyor belt 22. Then start the cleaning motor 45. The cleaning motor 45 rotates to drive the rotating shaft 43 and the cleaning brush 44 to rotate, and clean the food powder and debris adhering to the surface of the conveyor belt 22. The stubborn substances adhering to the surface of the conveyor belt 22 are scraped off by the scraper 42, and the gas knife 41 blows out gas to remove the powder adhering to the surface;

[0075] Step S3, when conveying foods containing sugar or gum-like substances, the two hydraulic rods 32 continue to extend to the right to drive the installation box 33 to move to the right. When the two gears 310 are respectively in contact with the two gear plates 311, the two gear plates 311 move to the right, so that the two gears 310 drive the moving cleaning plate 36 to rotate counterclockwise by 180 degrees through the rotating rod 35, so that the moving cleaning plate 36 is in contact with the cleaning liquid at the bottom of the installation box 33. Then control the two hydraulic rods 32 to retract to reset the position of the installation box 33. During the reset process of the installation box 33, the two gear plates 311 move to the left, so that the two gears 310 drive the rotating rod 35 and the moving cleaning plate 36 to rotate clockwise, and under the action of the guide groove, the moving cleaning plate 36 is reset and contacts the bottom of the conveyor belt 22, thereby cleaning the conveyor belt 22. Before cleaning, the food powder and debris adhering to the surface of the conveyor belt 22 are cleaned by the rotation of the cleaning brush 44. After cleaning, the conveyor belt 22 is dried by the gas knife 41, and the adhesion on the conveyor belt 22 is scraped off by the scraper 42. The extension and retraction of the hydraulic rod 32 are used to switch the sticking position and cleaning position of the moving cleaning plate 36;

[0076] Step S4, when the device needs to be deeply cleaned, start the two electric telescopic rods 53. The two electric telescopic rods 53 retract to the left, driving the two sliding plates 52 to slide to the left respectively inside the two mounting seats 51. The movement of the two sliding plates 52 drives the right conveying roller 21 to move to the left, thereby canceling the tension state of the conveyor belt 22;

[0077] When the two sliding plates 52 move to the left, they will simultaneously drive the two driving tooth plates 64 to move to the left. When the two driving tooth plates 64 respectively contact the two driven gears 63 and continue to move to the left, the two driven gears 63 are driven to rotate by the two driving tooth plates 64. The two driven gears 63 drive the support frame 62 to rotate counterclockwise through the rotating shafts 61, thereby supporting the conveyor belt 22, so as to facilitate the deep cleaning of the conveyor belt 22 and the conveying roller 21.

[0078] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
