Description

Technical Field

[0001] This invention relates to the field of food processing and conveying technology, and in particular to a food conveying device with aseptic protection function. Background Technology

[0002] In the food processing industry, food safety and hygiene are core elements for protecting consumer health, and the aseptic nature of the food transportation process, as a crucial link in the production process, directly affects the quality of the final product.

[0003] Application number CN201821718459.5 discloses a food conveying device with aseptic protection function, including a placement platform, a protective shell, a semiconductor cooler, a cooling cover, a fan, a motor, a drive wheel, an auxiliary wheel, a track, a protective cover, an operating hole, a connecting protective sleeve, and a fixing ring. This food conveying device with aseptic protection function has an ingenious structure and powerful function. First, through the protective conveying design, it can effectively prevent external particles from contacting the food during the conveying process, thus improving the hygiene of food conveying. Second, through the cooperation of the cooling mechanism, it can also effectively prevent high temperature from affecting the food's solidification process, effectively avoiding the problem of food spoilage due to high temperature. Ultimately, it is conducive to the promotion and application in the food processing industry.

[0004] Based on the above patent search and understanding of the application of existing food conveying devices: some devices can only perform simple disinfection and sterilization on the food itself, but neglect the conveying equipment itself, especially the cleaning and aseptic maintenance of the conveyor belt surface. During long-term use, food particles, stains and microorganisms are easily left on the conveyor belt. These residues will not only contaminate the food that is subsequently conveyed, but may also breed bacteria, affecting the shelf life and safety of the food.

[0005] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a food conveying device with aseptic protection function in order to achieve a more practical purpose. Summary of the Invention

[0011] Furthermore, gear A is located at the lower left of the adjustment frame, and the wiping wet roller, particle wiping roller, and wet stain wiping roller are designed at the same height, and all of them are located below the conveyor belt.

[0012] Furthermore, an adjustment plate is slidably connected to the left and right sides of the adjustment frame, the two adjustment plates are symmetrically distributed, and an elastic plate is elastically connected to the top of the two adjustment plates by a spring. The two elastic plates are slidably connected to the left and right sides of the adjustment frame, and the middle position of the two adjustment plates is rotatably connected to the left and right sides of the perforated roller, with the perforated roller located directly above the wiping wet roller.

[0013] Furthermore, a threaded hole is provided at the top center of each of the two elastic plates, and an adjusting bolt B is rotatably connected in the threaded hole of each elastic plate.

[0014] Furthermore, the perforated roller has a hollow interior and a tapered groove on its circumference. An absorption pump is fixedly connected to the left side of the adjustment plate on the left side of the adjustment frame. The air inlet of the absorption pump is connected to the left side of the perforated roller. A detachable storage cover is provided on the left side of the absorption pump.

[0015] Furthermore, an adjustable adjustment frame is provided at the rear end of the conveyor belt. A mating frame is fixedly connected to the lower front of the adjustment frame. Both ends of the mating frame have through-hole plates. The through-hole plates on both sides of the mating frame are slidably connected to the sides of the reciprocating frame.

[0016] Furthermore, the motor C shaft is fixedly connected to the mating shaft, which is located inside the mating frame. A cam is symmetrically fixedly connected to each side of the mating shaft, and the two cams are respectively in contact with the bottom sides of the reciprocating frame. A circular ring-shaped limiting cylinder is fixedly connected to the left side of the mating frame, and the inner wall of the limiting cylinder is corrugated. The left side of the mating shaft is located in the middle of the limiting cylinder. A rotating wheel is fixedly connected to the left side of the mating shaft. The rotating wheel is located inside the limiting cylinder. Six extendable arms are elastically rotated on the circumference of the rotating wheel. When the rotating wheel is stopped, the six extendable arms are retracted and in contact with the circumference of the rotating wheel.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. During normal use of the conveyor belt, material residues and particles may remain on its surface. Continued use of the conveyor belt can easily interfere with the product itself. Therefore, the absorption pump is activated. The absorption pump itself generates suction force, which, through the hollow structure of the perforated roller and the cooperation of the conical groove on the circumferential surface, performs dust suction on the conveyor belt area located below the perforated roller. The particles and residues present in the conveyor belt conveying area are adsorbed and transferred to the storage cover for temporary storage. The storage cover can be removed for cleaning later, thus avoiding the presence of particles and residues in the conveyor belt conveying area.

[0018] 2. When the upper end of the conveyor belt adsorbs residual adhesive material, and the absorption pump cannot remove it through adsorption force, the adhesive residue contacts the perforated roller, and the spring between the adjusting plate and the elastic plate contracts. The perforated roller and the conveyor belt will not interfere with each other, and the normal operation of the conveyor belt will not be affected.

[0019] 3. When motor C is started, it will drive the mating shaft to rotate. The two cams will complete their rotation. Through the contact between the two cams and the bottom of the reciprocating frame, and the return spring's restriction on the reciprocating frame, the reciprocating frame will drive the scraping component to move up and down in an inertial motion. The up and down reciprocating motion of the scraping component assists in scraping away the solidified material behind the conveyor belt, and can better cover the scraping area at the rear of the conveyor belt. In addition, if motor C drives the mating shaft to rotate too fast, the rotational inertia of the mating shaft will drive the six extension arms that elastically rotate on the outside of the rotating wheel to unfold until the unfolded position of the six extension arms contacts the corrugated position of the inner wall of the limiting cylinder for friction, reducing the rotational inertia of the rotating wheel, thereby limiting the rotational speed of the mating shaft, adjusting the up and down movement speed of the scraping component, and avoiding the scraping component having too much scraping inertia on the solidified material of the conveyor belt, which could damage the transmission capacity of the conveyor belt.

[0020] 4. The motor B shaft drives the wiping wet roller to rotate. The direction of rotation of the wiping wet roller is the same as that of the conveyor belt. At this time, the wiping wet roller is driven by the meshing of gears A and B and gear C respectively. The particle wiping roller and the wet stain wiping roller rotate in the opposite direction to the wiping wet roller. The particle wiping roller and the wet stain wiping roller perform secondary and tertiary wiping cleaning on the position of the conveyor belt that is attracted by the perforated roller. This ensures that the conveyor belt is cleaned once a week during transportation, avoiding manual wiping and avoiding the possibility that regular cleaning cannot guarantee that the transportation mechanism will not get dirty during use.

[0021] 5. After connecting valve B to the water pipe that delivers the disinfectant solution, open valve B. The disinfectant solution will be immersed in the wiping roller to clean the residual debris adhering to the conveyor belt. The cleaned residue and disinfectant solution will fall into the storage tank for temporary storage due to gravity. At the same time, the wet wiping roller will clean the water source on the conveyor belt. When the conveyor belt continues to work, the heat generated by its own rotation and friction will evaporate the residual water source.

[0022] 6. When gear A meshes with gear D, the wiping wet roller and the perforated roller rotate in opposite directions, and the rotation direction of the perforated roller is also opposite to that of the conveyor belt. At this time, the perforated roller rotates while the absorption pump is in operation, allowing the perforated roller to adsorb and collect particulate residues on the surface of the conveyor belt over a larger area, and avoiding adsorption blockage of the perforated roller.

The storage tank 106 is located at the lower middle position inside the mounting frame 2 and is located directly below the wiping wet roller 206.

[0033] Among them, gear A207 is located at the lower left of the adjusting frame 201.

[0036] The perforated roller 303 has a hollow interior and a tapered groove on its circumference. An absorption pump 305 is fixedly connected to the left side of the adjusting plate 3 on the left side of the adjusting frame 201. The air inlet of the absorption pump 305 is connected to the left side of the perforated roller 303. A detachable storage cover 306 is provided on the left side of the absorption pump 305. A gear D304 is fixedly installed on the right side of the perforated roller 303. The bottom of the gear D304 meshes with the top of the gear A207.

[0037] The rear end of the conveyor belt 101 is equipped with an adjustable adjustment frame 111. The lower front of the adjustment frame 111 is fixedly connected to the mating frame 112. Both ends of the inner side of the mating frame 112 are provided with through-hole plates. The through-hole plates on both sides of the mating frame 112 are slidably connected to the sides of the reciprocating frame 113. A return spring 131 is fixedly fixed on the lower sides of the reciprocating frame 113. The top of the return spring 131 is in contact with the bottom of the through-hole plate of the mating frame 112. A scraper 114 is fixedly connected to the top of the reciprocating frame 113. The front end of the scraper 114 has a serrated design, and the serrations of the scraper 114 are staggered. The serrations of the scraper 114 are in contact with the rear end of the conveyor belt 101. A motor C115 is fixedly connected to the right side of the mating frame 112.

[0038] Among them, the rotating shaft of motor C115 is fixedly connected to the mating shaft 116, which is located inside the mating frame 112. A cam 117 is symmetrically fixedly connected to both sides of the mating shaft 116. The two cams 117 are respectively in contact with the bottom sides of the reciprocating frame 113. A circular ring-shaped limiting cylinder 118 is fixedly connected to the left side of the mating frame 112, and the inner wall of the limiting cylinder 118 is corrugated. The left side of the mating shaft 116 is located in the middle of the limiting cylinder 118. A rotating wheel 119 is fixedly connected to the left side of the mating shaft 116. The rotating wheel 119 is located inside the limiting cylinder 118. Six extension arms 191 are elastically rotated on the circumference of the rotating wheel 119. When the rotating wheel 119 is stopped, the six extension arms 191 are retracted and in contact with the circumference of the rotating wheel 119.

[0039] When using: First, the food material is placed at the top front end of the conveyor belt 101. The conveyor belt 101 transports the food material from the top front end to the rear, transferring it to the interior of the sterilization machine 1 for sterilization. When the food material passes between the two auxiliary plates 105, the motor A104 is started to drive the bidirectional screw 141 to rotate. Through the cooperation between the bidirectional screw 141 and the threaded holes of the two auxiliary plates 105, the two auxiliary plates 105 will move synchronously in opposite directions, thereby adjusting the distance between the two auxiliary plates 105. This facilitates the centered positioning of the food material in the middle of the conveyor belt 101 for transportation, avoiding manual adjustment of the food material's position.

[0040] During normal use of the conveyor belt 101, food residues and particles may remain on its surface. Continued use of the conveyor belt 101 could easily interfere with the product itself. Therefore, the absorption pump 305 is activated. The absorption pump 305 generates suction force, which, through the hollow structure of the perforated roller 303 and the cooperation of the circumferential conical groove, vacuums the area of ​​the conveyor belt 101 located below the perforated roller 303. The particles and residues present in the conveying area of ​​the conveyor belt 101 are adsorbed and transferred to the storage cover 306 for temporary storage. The storage cover 306 can be removed for cleaning afterward, thus preventing particles and residues from remaining in the conveying area of ​​the conveyor belt 101.

[0041] When food residue adheres to the upper end of the conveyor belt 101 and the absorption pump 305 cannot remove it through adsorption, the residue contacts the perforated roller 303. The spring between the adjusting plate 3 and the elastic plate 301 contracts, and the perforated roller 303 will not interfere with the conveyor belt 101, thus not affecting the normal operation of the conveyor belt 101.

[0042] In addition, although the absorption pump 305 performs particle and residue adsorption treatment on the conveyor belt 101 conveying area through the perforated roller 303, a small amount of particles and food materials will still adhere to the conveyor belt 101. Therefore, the motor B204 is started, and the shaft of the motor B204 drives the wiping wet roller 206 to rotate. The direction of rotation of the wiping wet roller 206 is the same as that of the conveyor belt 101. At this time, the wiping wet roller 206 is driven by the meshing of gear A207 with gear B209 and gear C211 respectively. The particle wiping roller 208 and the wet stain wiping roller 210 rotate in the opposite direction to the wiping wet roller 206. The particle wiping roller 208 and the wet stain wiping roller 210 perform secondary and tertiary wiping cleaning on the part of the conveyor belt 101 that is adsorbed by the perforated roller 303 to ensure the cleanliness of the surface of the conveyor belt 101.

[0043] After valve B205 is connected to the water pipe that delivers disinfectant, valve B205 is opened. The disinfectant is then immersed in the wiping roller 206 to clean the residual debris adhering to the conveyor belt 101. The cleaned residue and disinfectant liquid will fall into the storage tank 106 for temporary storage due to gravity. At the same time, the wet wiping roller 210 cleans the water source on the conveyor belt 101. When the conveyor belt 101 continues to work, the heat generated by its own rotation and friction evaporates the residual water.

[0044] When gear A207 meshes with gear D304, the wiping wet roller 206 and the perforated roller 303 rotate in opposite directions. The rotation direction of the perforated roller 303 is also opposite to that of the conveyor belt 101. At this time, when the perforated roller 303 rotates and the absorption pump 305 is in working condition, the perforated roller 303 can adsorb and collect particulate residues on the surface of the conveyor belt 101 over a larger area, and avoids adsorption blockage of the perforated roller 303.

[0045] When the conveyor belt 101 is in normal transport and the absorption pump 305 is unable to handle the sticky and solidified material residue on the conveyor belt 101, the conveyor belt 101 will move the area of ​​solidified material to the rear and then contact the serrated position on the top of the scraper 114. The solidified material will be removed by the rotational inertia of the conveyor belt 101 without affecting the rotational ability of the conveyor belt 101. In addition, the scraper 114 can also limit the rear of the conveyor belt 101.

[0046] When the motor C115 is started, it will drive the mating shaft 116 to rotate. The two cams 117 will complete the rotation. Through the contact between the two cams 117 and the bottom position of the reciprocating frame 113, and the reset spring 131 to limit the reset of the reciprocating frame 113, the reciprocating frame 113 will drive the scraping part 114 to move up and down inertial motion. The up and down reciprocating motion of the scraping part 114 will assist in scraping the solidified food material behind the conveyor belt 101, and can better cover the scraping area at the rear of the conveyor belt 101. Furthermore, if the motor C115 drives the mating shaft 116 to rotate too fast, the rotational inertia of the mating shaft 116 will cause the six extension arms 191 that rotate elastically on the outside of the rotating wheel 119 to unfold until the unfolded position of the six extension arms 191 is in contact with the corrugated position of the inner wall of the limiting cylinder 118 to rub against each other, thereby reducing the rotational inertia of the rotating wheel 119, thereby limiting the rotational speed of the mating shaft 116, adjusting the up-and-down movement speed of the scraper 114, and avoiding the scraper 114 having too much scraping inertia on the solidified material of the conveyor belt 101, which could damage the transmission capacity of the conveyor belt 101.

[0047] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. The scope of protection of this disclosure shall be determined by the scope of the claims.
