Description

Technical Field

[0001] This invention relates to the field of food processing technology, specifically to a self-cleaning conveying device for food processing. Background Technology

[0002] During food processing, food needs to be transported by conveying equipment. When food raw materials or semi-finished products are transported on the conveyor belt, it is inevitable that debris, juice, powder and other impurities will remain on the surface of the conveyor belt. If they are not cleaned in time, these impurities will not only breed bacteria and affect food hygiene and safety, but may also contaminate other foods in the subsequent transportation process. In some cases, the accumulation of impurities may even cause the conveyor belt to run poorly, increasing the risk of equipment failure.

[0003] To address the aforementioned issues, existing technology 1 (Chinese Patent No. CN223267630U, Publication Date: 2025-08-26) discloses a food conveyor belt, comprising a frame, a first support frame, and a second support frame. The conveyor belt body is mounted on the inner side of the frame. The first support frame is fixed to the lower right side of the frame, and a cleaning mechanism is provided on its inner side. The cleaning mechanism includes a mounting base, a cleaning brush, a connecting plate, a limiting rod, and a first spring. The cleaning brush is tightly fitted to the lower part of the conveyor belt body, and the limiting rod is slidably connected to the mounting base via the first spring. The second support frame is fixed to the upper left side of the frame, and a guiding mechanism is provided within it. The guiding mechanism includes a first connecting wheel, a second connecting wheel, a fixing column, and a second guiding plate. This mechanism can automatically clean food residue from the conveyor belt, ensuring cleanliness and hygiene. It is easy to install and disassemble, simple and quick to operate, and convenient for cleaning. It can also separate food according to its size, facilitating separate conveying.

[0004] There is also prior art 2 (Chinese patent with announcement number CN119929445B, announcement date 2022-11-15) a cleaning and conveying device for food raw materials, including a cleaning box, a discharge valve and a cleaning and conveying unit; the cleaning box has a threaded sealing connection to the discharge valve on its side opening; the cleaning box is equipped with a cleaning and conveying unit; the cleaning and conveying unit includes a fixed seat, a fixed shaft and a rotating tube; the two outer surfaces of the cleaning box are symmetrically fixed with fixed seats; by two first motors rotating in opposite directions, two cleaning conveyor belts are driven to rotate in opposite directions, thereby realizing the function of circulating water rotation in the cleaning box, thereby moving and cleaning the food raw materials, and the cleaning speed can be adjusted according to different food types; by the alternating reciprocating movement of the two cleaning conveyor belts, opposite vortices are realized, thereby driving the food raw materials to tumble and clean quickly, achieving the function of cleaning food raw materials efficiently and without damage.

[0005] While existing technologies have achieved some degree of cleaning of conveyor belts or food ingredients, they still have some shortcomings. The existing cleaning methods are relatively simple, relying mainly on cleaning brushes or scrapers at fixed angles for passive scraping. It is difficult to flexibly adjust the cleaning force and angle according to different conditions such as the adhesion and thickness of impurities on the conveyor belt surface. When encountering stubborn adhesive impurities, it is easy to have incomplete cleaning problems.

[0006] Therefore, we propose a self-cleaning conveyor for food processing to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a self-cleaning conveyor for food processing, in order to solve the problem that the cleaning methods currently available on the market are relatively simple, and mostly rely on cleaning brushes or scrapers at fixed angles for passive scraping. It is difficult to flexibly adjust the cleaning force and angle according to different conditions such as the adhesion and accumulation thickness of impurities on the conveyor belt surface. When encountering stubborn adhesive impurities, it is easy to have incomplete cleaning.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a self-cleaning conveyor for food processing, comprising a conveyor body, a conveyor belt on the conveyor body, and a fixed frame fixedly connected to the lower outer side of the conveyor body. A positioning shaft is fixedly connected inside the fixed frame, and a scraper for scraping impurities from the surface of the conveyor belt is rotatably mounted on the outer side of the positioning shaft. An adjustment mechanism is provided between the lower part of the scraper and the inside of the fixed frame. The adjustment mechanism drives the scraper to rotate by the lateral movement of its included drive rod, thereby meeting the cleaning needs under different conditions. A cleaning mechanism is also provided inside the fixed frame and on the surface of the scraper. The cleaning mechanism drives the deformation of its included cleaning soft plate by the operation of the adjustment mechanism, thereby vibrating and cleaning the impurities remaining on its surface.

[0009] Preferably, the outer surface of the conveyor belt is fixedly connected with abutment blocks at equal intervals, and the inside of the fixing frame is fixedly connected with a fixing airbag. When the conveyor belt is running, it drives the abutment blocks to squeeze the fixing airbag.

[0010] Preferably, the fixed airbag is provided with a connecting pipe, and the other end of the connecting pipe is provided with a jet pipe, and the air outlet of the jet pipe is set towards the scraper side. The gas inside the fixed airbag is transported to the jet pipe and sprayed out from the air outlet to blow away the scraped impurities.

[0011] Preferably, the adjustment mechanism includes an electric telescopic rod, which is fixedly connected to the inner side of the fixed frame, and a movable plate is fixedly connected to the output end of the electric telescopic rod. An abutment rod is fixedly connected to the upper surface of the movable plate, and two sets of movable plates are symmetrically arranged about the center point of the fixed frame.

[0012] Preferably, a buffer spring is fixedly connected between the side of the scraper and the inner wall of the fixed frame, and a linkage plate is fixedly connected below the scraper. A linkage groove is provided on the linkage plate, and a drive rod is slidably connected inside the linkage groove. By sliding the drive rod in the linkage groove, the scraper is driven to rotate around the positioning shaft.

[0013] Preferably, a drive plate is fixedly connected to the inner end of the drive rod, and an abutment groove is provided on the drive plate. The abutment groove is arranged in an inclined structure. An abutment rod is fixedly connected to the upper surface of the moving plate, and the abutment rod is slidably disposed inside the abutment groove.

[0014] Preferably, the cleaning mechanism includes a squeezing plate, which is fixedly connected to the inner side of the movable plate. A soft cavity is fixedly connected between the two sets of squeezing plates, and a connecting hose is connected through the side of the soft cavity.

[0015] Preferably, the scraper is inclined to one side of the conveyor belt running direction, and a cleaning airbag is fixedly connected to the scraper side facing the conveyor belt. The cleaning airbag is connected to the other end of the connecting hose.

[0016] Preferably, a cleaning soft plate is fixedly connected to the outer surface of the cleaning airbag, and the cleaning soft plate is arranged in an arc shape when viewed from the side. The cleaning soft plate deforms synchronously with the deformation of the cleaning airbag.

[0017] Compared with the prior art, the beneficial effects of the present invention are: (1) The scraper is inclined and the upper end of the scraper is in contact with the surface of the conveyor belt. It can effectively scrape off solid impurities, viscous juices and other substances attached to the surface of the conveyor belt during the operation of the conveyor belt, preventing impurities from remaining on the surface of the conveyor belt for a long time. The buffer spring can always give the scraper an upward elastic force, ensuring that the scraper and the surface of the conveyor belt maintain a good contact and fit, and ensuring the stability of the scraping effect.

[0018] (2) When it is necessary to clean impurities of different thicknesses and viscosity, or when the conveyor belt is worn to a certain extent and the surface height changes, start the electric telescopic rod. The electric telescopic rod drives the moving plate to move back and forth, which in turn drives the drive rod to move left and right, thereby pushing or pulling the linkage plate, causing the scraper to rotate around the positioning shaft, thereby changing the angle between the scraper and the surface of the conveyor belt and the contact force to adapt to different cleaning conditions.

[0019] (3) When the moving plate moves laterally, the squeezing plate on its inner side will squeeze or release the soft cavity, causing the cleaning airbag to expand or contract. Since the cleaning airbag is fixedly connected to the outer surface of the cleaning airbag with an arc-shaped cleaning soft plate, the expansion or contraction of the cleaning airbag will cause the cleaning soft plate to deform, causing the cleaning soft plate to vibrate and deform, which will shake off the impurities that may be scraped off the scraper surface, such as small food scraps and sticky residues, and keep the scraper surface clean.

[0020] (4) During the operation of the conveyor belt, the fixed contact blocks on its outer surface at equal intervals will periodically squeeze the fixed airbags inside the fixed frame. After being squeezed, the gas in the fixed airbags will be sprayed out from the jet pipe toward the air outlet on the side of the scraper. The airflow can blow toward the contact area between the scraper and the conveyor belt and the scraping surface of the scraper to prevent impurities from adhering again. At the same time, it can also blow away the impurities on the scraper surface and the impurities shaken off by the vibration of the cleaning soft plate, blowing them away from the inside of the equipment, avoiding the accumulation of impurities in the fixed frame, and further improving the overall cleaning effect.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1: As Figures 1-3 , Figure 5 and Figure 9 The present invention provides the following technical solution: a self-cleaning conveyor for food processing, wherein a conveyor body 1 is provided with a conveyor belt 2, and a fixed frame 5 is fixedly connected to the lower outer side of the conveyor body 1. Abutment blocks 3 are fixedly connected at equal intervals on the outer surface of the conveyor belt 2. A positioning shaft 9 is fixedly connected inside the fixed frame 5, and a scraper 11 for scraping impurities on the surface of the conveyor belt 2 is rotatably arranged on the outer side of the positioning shaft 9. A buffer spring 10 is fixedly connected between the side of the scraper 11 and the inner wall of the fixed frame 5. A fixed airbag 4 is fixedly connected inside the fixed frame 5. When the conveyor belt 2 is running, it drives the abutment blocks 3 to squeeze the fixed airbag 4. A connecting pipe 7 is provided through the two sets of fixed airbags 4, and a jet pipe 6 is provided through the other end of the connecting pipe 7. The air outlet of the jet pipe 6 is arranged facing the scraper 11. The gas inside the fixed airbag 4 is transported to the jet pipe 6 and sprayed out from the air outlet to blow away the scraped impurities.

[0025] A scraper 11 is provided, with its upper end in contact with the surface of the conveyor belt 2. During the operation of the conveyor belt 2, it can effectively scrape off solid impurities, viscous liquids, etc., adhering to its surface, preventing impurities from remaining on the surface of the conveyor belt 2 for a long time. The scraper 11 is rotatably connected to the fixed frame 5 through the positioning shaft 9. The buffer spring 10 provided below it can always provide an upward elastic force to the scraper 11, ensuring that the scraper 11 and the surface of the conveyor belt 2 maintain a good contact and fit. Even if there is slight unevenness on the surface of the conveyor belt 2, it can be adaptively adjusted by the extension and contraction of the buffer spring 10 to ensure the stability of the scraping effect.

[0026] During the operation of the conveyor belt 2, the abutment blocks 3, evenly distributed on its outer surface, move synchronously with the cyclic rotation of the conveyor belt 2. When the abutment blocks 3 move into the interior of the fixed frame 5 and come into contact with the fixed airbag 4, they exert a squeezing effect on the fixed airbag 4. The fixed airbag 4 is made of elastic rubber. After being squeezed by the abutment blocks 3, its internal volume shrinks and the gas pressure increases. Since the fixed airbag 4 is connected to the jet pipe 6 through the connecting pipe 7, the compressed air in the fixed airbag 4 flows along the connecting pipe 7 to the jet pipe 6 under pressure. The jet pipe 6 is installed inside the fixed frame 5 near the scraper 11. It has multiple small air outlets on the side facing the contact area between the scraper 11 and the conveyor belt 2. When the compressed air is ejected from these air outlets, it forms multiple airflows that directly act on the surface of the conveyor belt 2 after the scraper 11 has removed impurities and on the scraper 11 itself. In addition to the surface, for small food scraps or liquid residues that may still be partially adhered to the surface of the conveyor belt 2 after being scraped off by the scraper 11, the high-speed airflow can quickly blow them away from the surface of the conveyor belt 2, preventing them from re-attaching or being carried to the next process during subsequent conveying. At the same time, the airflow will also blow the impurities remaining on the surface of the scraper 11 due to the scraping action, as well as the impurities shaken off by the cleaning soft plate 20, to the outside of the fixed frame 5 or the preset collection area, effectively avoiding the problem of impurities accumulating inside the fixed frame 5 and affecting the normal operation of the equipment or the growth of bacteria. As the conveyor belt 2 continues to run, the contact block 3 will periodically squeeze and release the fixed airbag 4, so that the jet pipe 6 can intermittently spray airflow, forming a continuous purging effect. This, together with the scraping action of the scraper 11 and the vibration cleaning action of the cleaning soft plate 20, significantly improves the cleaning efficiency and cleanliness of the conveyor belt 2.

[0027] Example 2: When the characteristics of the food material being conveyed on conveyor belt 2 need to be considered, such as thicker impurities, stronger viscosity, or slight changes in the height of conveyor belt 2 due to wear after long-term use, which affects the scraping effect of scraper 11, such as... Figures 3-7The present invention provides the following technical solution: a self-cleaning conveying device for food processing, wherein an adjustment mechanism is provided between the lower part of the scraper 11 and the interior of the fixed frame 5. The adjustment mechanism drives the scraper 11 to rotate by the lateral movement of the drive rod 14 included therein, so as to meet the cleaning needs under different conditions. The adjustment mechanism includes an electric telescopic rod 8, which is fixedly connected to the inner side of the fixed frame 5, and a moving plate 15 is fixedly connected to the output end of the electric telescopic rod 8. An abutment rod 18 is fixedly connected to the upper surface of the moving plate 15. The moving plate 15 is about the fixed frame 5. Two sets of components are symmetrically arranged at the center point of the frame 5. A linkage plate 12 is fixedly connected to the lower part of the scraper 11, and a linkage groove 13 is provided on the linkage plate 12. A drive rod 14 is slidably connected inside the linkage groove 13. By sliding the drive rod 14 in the linkage groove 13, the scraper 11 is driven to rotate around the positioning shaft 9. A drive plate 16 is fixedly connected to the inner end of the drive rod 14, and an abutment groove 17 is provided on the drive plate 16. The abutment groove 17 is set in an inclined structure. An abutment rod 18 is fixedly connected to the upper surface of the moving plate 15, and the abutment rod 18 is slidably arranged inside the abutment groove 17.

[0028] The electric telescopic rod 8 in the adjustment mechanism adjusts the working state of the scraper 11. The cylinder of the electric telescopic rod 8 is fixed to the side of the fixed frame 5 by bolts, and its output end is rigidly connected to the moving plate 15 to ensure the stability of power transmission. When the electric telescopic rod 8 receives a control signal and starts working, its output end will drive the moving plate 15 to move back and forth along the slide rail preset inside the fixed frame 5. The upper surface of the moving plate 15 is welded with a vertically upward extending abutment rod 18. The top of the abutment rod 18 is embedded in the abutment groove 17 opened on the drive plate 16, and the two are in sliding fit. Since the abutment groove 17 has an inclined structure at a certain angle, when the moving plate 15 drives the abutment rod 18 to move back and forth, the abutment rod 18 will slide relative to the abutment groove 17. At this time, the inclined inner wall of the abutment groove 17 will abut against the scraper 11. The rod 18 generates a lateral force, which in turn pushes or pulls the drive plate 16 to move left and right. The two ends of the drive plate 16 are fixedly connected to the inner ends of the drive rod 14. Therefore, the left and right movement of the drive plate 16 will synchronously drive the drive rod 14 to move laterally. The outer end of the drive rod 14 is slidably connected to the linkage groove 13 on the linkage plate 12 below the scraper 11. When the drive rod 14 moves laterally, it will slide in the linkage groove 13 and apply a pushing or pulling force to the linkage plate 12, so that the linkage plate 12 drives the scraper 11 to rotate clockwise or counterclockwise around the positioning shaft 9. This changes the angle between the scraper 11 and the surface of the conveyor belt 2, flexibly adapting to the cleaning needs of impurities of different thicknesses and viscosity, as well as the height changes of the surface of the conveyor belt 2 due to wear and other reasons, ensuring that a good scraping effect can be maintained under various working conditions.

[0029] Example 3: Figures 5-8 The present invention provides the following technical solution: a self-cleaning conveying device for food processing, wherein a cleaning mechanism is provided inside the fixed frame 5 and on the surface of the scraper 11. The cleaning mechanism drives the deformation of the cleaning soft plate 20 contained therein through the operation of the adjustment mechanism, and vibrates to clean the impurities remaining on its surface. The cleaning mechanism includes a squeezing plate 21, which is fixedly connected to the inner side of the moving plate 15. A soft cavity 22 is fixedly connected between the two sets of squeezing plates 21, and a connecting hose 23 is connected through the side of the soft cavity 22. The scraper 11 is inclined to one side in the direction of the conveyor belt 2, and a cleaning airbag 19 is fixedly connected to the side of the scraper 11 facing the conveyor belt 2. The cleaning airbag 19 is connected through the other end of the connecting hose 23. The cleaning soft plate 20 is fixedly connected to the outer surface of the cleaning airbag 19, and the cleaning soft plate 20 is arranged in an arc-shaped structure when viewed from the side. The cleaning soft plate 20 deforms synchronously with the deformation of the cleaning airbag 19.

[0030] When the movable plate 15 in the adjustment mechanism moves laterally under the drive of the electric telescopic rod 8, the squeezing plate 21 fixedly installed on the inner wall of the movable plate 15 will move synchronously. Since the two sets of movable plates 15 are symmetrically arranged, when they approach each other, the squeezing plates 21 on both sides will jointly exert a squeezing force on the soft cavity 22 located between them. After being squeezed, the volume of the sealed space inside the soft cavity 22 decreases, and the gas pressure increases accordingly. At this time, the compressed gas inside the soft cavity 22 will be forced into the cleaning airbag 19 fixedly connected to the surface of the scraper 11 facing the conveyor belt 2 through the connecting hose 23. The cleaning airbag 19 is also made of elastic material. After being filled with gas, it will expand and deform, and its volume will increase. When the movable plates 15 move away from each other under the drive of the electric telescopic rod 8, the squeezing force of the squeezing plate 21 on the soft cavity 22 disappears, and the soft cavity 22 returns to its original position under its own elasticity. When the airbag 19 is in a negative pressure state, the gas inside will flow back to the soft cavity 22 through the connecting hose 23, causing the airbag 19 to contract. Since the cleaning soft plate 20 with an arc-shaped structure in side view is fixedly connected to the outer surface of the cleaning airbag 19, when the cleaning airbag 19 expands or contracts, it will simultaneously drive the cleaning soft plate 20 to produce corresponding bending deformation and slight vibration, which effectively acts on the scraping surface of the scraper 11. Various impurities that may adhere to and accumulate on the scraping surface of the scraper 11 during the scraping of impurities on the surface of the conveyor belt 2, such as fine flour particles, meat residue, fruit peels, and sticky syrup and sauce residues, are shaken off by vibration, thereby keeping the scraping surface of the scraper 11 clean at all times, avoiding the accumulation of impurities on the surface of the scraper 11 and affecting the subsequent scraping effect, and ensuring that the scraper 11 can continuously and efficiently clean the conveyor belt 2.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
