Description

Technical Field

[0001] This invention relates to the field of food industrial processing and intelligent manufacturing equipment technology, and in particular to a cooling food conveying device and method. Background Technology

[0002] Cooled conveying (usually referring to the integration of rapid cooling processes on the production line or low-temperature conveying under specific conditions) is a key technology in the food industry. The core reasons for this can be attributed to the following key points, which are interconnected and work together to ensure the safety, quality, and economic benefits of food.

[0003] Existing cooling food conveying equipment involves placing food on a conveyor belt and allowing it to pass through a cooling chamber for cooling. However, since the food is conveyed inside the cooling chamber, the lower surface of the food is in direct contact with the conveyor belt, which creates a cooling blind spot. The part of the food at the contact point has poor cooling effect. In addition, the food is prone to stacking due to friction during the conveying process, which further reduces the cooling effect. Summary of the Invention

[0004] This invention discloses a cooling food conveying device, aiming to solve the technical problems of existing cooling food conveying devices. In the process of using these devices, food is placed on a conveyor belt and passed through a cooling chamber for cooling and conveying. However, the food is conveyed inside the cooling chamber, and the lower surface of the food is in direct contact with the conveyor belt. This creates a cooling blind zone, and the cooling effect is poor in the part of the food at the contact point. At the same time, the food is prone to stacking due to friction during the conveying process, which further reduces the cooling effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cooling food conveying device includes four shaft plates.

[0008] In a preferred embodiment, the outer wall of the hollow rotating shaft is provided with a circumferential branch hole, and a branch pipe is fixedly connected inside each branch hole, with one end of the branch pipe inserted into the interior of an adjacent vacuum tube.

[0009] In a preferred embodiment, air plates are fixedly connected to the inner walls of both sides of the docking frame, and airflow elongated holes are equally spaced on opposite sides of the two air plates.

An air extraction pipe is fixedly connected to the air inlet end of the circulation pump, and one end of the air extraction pipe is inserted into the interior of one of the air plates. A circulation pipe is fixedly connected to the air delivery end of the circulation pump and is inserted into the interior of the cooling box. An air guide pipe is fixedly connected to the air guide end of the vacuum pump, and one end of the air guide pipe is inserted into the interior of the other air plate.

[0010] In a preferred embodiment, the cooling box is provided with an anti-stacking mechanism between the turning mechanism and the circulating sealing mechanism. The anti-stacking mechanism includes an operating plate, which is fixedly connected to the inner walls of both sides of the cooling box. An adjustment hole is opened on the top of the operating plate, and two positioning slide rods are fixedly connected to the inner walls of both sides of the adjustment hole.

[0011] In a preferred embodiment, the top of each end of the operating plate at both ends of the adjustment hole is fixedly connected to an end block, and a hydraulic cylinder is fixedly connected to one side of each end block. The output ends of the two hydraulic cylinders are fixedly connected to a sliding bracket, which is slidably connected to two positioning slide rods. A motor plate is fixedly connected to one side of the sliding bracket, and a drive motor is fixedly connected to the top of the motor plate. The output shaft of the drive motor is fixedly connected to a drive shaft via a coupling. An outer ring is fixedly connected to the outer wall of the drive shaft.

The adjusting sleeve is sleeved on the outer wall of the drive shaft, and a push rotating plate is fixedly connected to the bottom of the adjusting sleeve.

[0012] In a preferred embodiment, the top of the control panel has a lifting hole, and a lifting baffle is inserted into the lifting hole. An upper frame is fixedly connected to the top of the control panel, and two lifting cylinders are fixedly connected to the top of the upper frame.

Pressure sensors are fixedly connected at equal intervals inside the installation groove. Two telescopic connecting rods are fixedly connected to the periphery of each pressure sensor in the installation groove.

[0013] In a preferred embodiment, a conveyor motor is fixedly connected to one side of one of the shaft plates, and the output shaft of the conveyor motor is connected to one end of the transmission roller via a coupling. A circulating refrigeration mechanism is fixedly connected to the top of the cooling box, and inner support rods are fixedly connected at equal distances to the opposite sides of the two connecting rods, with the inner support rods in contact with the conveyor belt.

[0014] A cooling food conveying method, using a cooling food conveying device as described above, includes the following steps: Step 1: Place the food on the conveyor belt. The conveyor motor drives the conveyor rollers to rotate, thereby moving the conveyor belt. The food enters the cooling box along with the conveyor belt, and the circulating refrigeration mechanism cools the inside of the cooling box. Step 2: After the food enters the cooling and sealing box along the conveyor belt, start the second drive motor. The second drive motor drives the rotating plate to rotate. Adjust the first hydraulic cylinder to drive the rotating plate to move back and forth, thereby flattening the stacked food and preventing the cooling effect from being reduced due to stacking. At the same time, the flattened food is transported to the lifting baffle by the conveyor belt. When a specified number of pressure sensors reach a specified value, the lifting cylinder moves the lifting baffle upward to realize the sorting of the food. Step 3: After being spread and arranged, the food moves along the conveyor belt to the area below the flipping mechanism. The food then moves along the anti-jamming guide frame to the area below the corresponding vacuum suction cup. The vacuum pump is running, and the vacuum pumps on the long vacuum tube vacuum-adsorb the food below. The drive motor drives the hollow shaft to rotate. When the food is passively rotated 120°, the contact point between the food and the conveyor belt moves along the conveyor belt, causing the food to be flipped at a 60° angle. The solenoid valve on the long vacuum tube closes, and the vacuum suction cup loses its suction force on the food. The food gradually falls down with the rotation of the conveyor belt, achieving the flipping of the food. The food is flipped twice during the entire conveying process. After the two flips, the food is removed from the cooling and sealing box by the conveyor belt.

[0015] As can be seen from the above, the cooling food conveying equipment provided by the present invention has the following technical effects: when food is conveyed inside the cooling sealed box, the anti-stacking mechanism spreads and organizes it, and then it enters the area below the flipping mechanism. The food moves along the anti-jamming guide frame to the area below the corresponding vacuum suction cup. The vacuum pump is in operation, and the vacuum pumps on the long vacuum tube perform vacuum adsorption on the food below. The drive motor drives the hollow rotating shaft to rotate. When the food is passively rotated 120°, the contact point between the food and the conveyor belt moves along the conveyor belt, so that the food presents a 60° angle after being flipped. The solenoid valve located on the long vacuum tube closes, and the vacuum suction cup loses its adsorption force on the food. The food gradually falls down with the rotation of the conveyor belt, realizing the flipping of the food. This ensures that there are no blind spots in the contact of the food during the cooling conveying process, and improves the technical effect of food cooling conveying. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] The cooling food conveying device disclosed in this invention is mainly applied to the use of existing cooling food conveying devices. In this process, food is placed on a conveyor belt and passed through a cooling chamber to achieve cooling and conveying. However, when the food is conveyed inside the cooling chamber, the lower surface of the food is in direct contact with the conveyor belt, which creates a cooling blind zone. The part of the food at the contact point has poor cooling effect. At the same time, the food is prone to stacking due to friction during the conveying process, which further reduces the cooling effect of the food.

[0029] Reference Figures 1-10A cooling food conveying device includes four shaft plates 1. Each pair of adjacent shaft plates 1 has a transmission roller 3 connected to its opposite side via bearings. The outer walls of the two transmission rollers 3 are fitted with the same conveyor belt 5. A single docking rod 6 is fixedly connected to two shaft plates 1 on one side. Two fixing plates 10 are fixedly connected to the top of each of the two docking rods 6. A cooling sealing box 9 is fixedly connected to multiple fixing plates 10. The cooling sealing box 9 contains two sets of tipping mechanisms 11. Each tipping mechanism 11 includes a hollow rotating shaft 1101, with both ends of the hollow rotating shaft 1101 connected to the inner walls of both sides of the cooling sealing box 9 via bearings. A drive motor 1104 is fixedly connected to the outer wall of the cooling sealing box 9 near the end of the hollow rotating shaft 1101. The output shaft of the drive motor 1104 is connected to one end of the hollow rotating shaft 1101 via a coupling. Mounting rods 1105 are distributed in a ring on the outer wall of the hollow rotating shaft 1101. A connecting collar 110 is fixedly connected to the outer wall of each mounting rod 1105. 9. A fine-tuning rail 1112 is fixedly connected to the side of the connecting collar 1109 away from the hollow rotating shaft 1101. A fine-tuning slider 1110 is slidably connected inside the fine-tuning rail 1112. A self-adjusting spring rod 1113 is fixedly connected to the side of the fine-tuning slider 1110 facing the connecting collar 1109. One end of the self-adjusting spring rod 1113 is fixedly connected to one side of the connecting collar 1109. An extension rod 1111 is fixedly connected to the other side of the fine-tuning slider 1110. The end of the extension rod 1111... A vacuum tube 1102 is fixedly connected. Vacuum holes are evenly spaced on the arc surface of the vacuum tube 1102 away from the hollow rotating shaft 1101. A vacuum suction cup 1103 is fixedly connected inside each vacuum hole. A solenoid valve is connected to the outer wall of the connection between the vacuum tube 1102 and the vacuum suction cup 1103 through a flange. An anti-jamming guide frame 1106 is fixedly connected to the outer wall of the vacuum tube 1102. The lowest point of the anti-jamming guide frame 1106 is at the same horizontal level as the vacuum suction cup 1103.

[0030] In specific application scenarios, when food is transported inside the cooling and sealing box 9, the anti-stacking mechanism 12 spreads and organizes it, and then it enters the area below the flipping mechanism 11. The food moves along the anti-jamming guide frame 1106 to the area below the corresponding vacuum suction cup 1103. The vacuum pump 703 is in operation, and the vacuum pumps 703 on the vacuum tube 1102 perform vacuum adsorption on the food below. The drive motor 1104 drives the hollow rotating shaft 1101 to rotate. When the food is passively rotated 120°, the contact point between the food and the conveyor belt 5 moves along the conveyor belt 5, so that the food presents a 60° angle after being flipped. The solenoid valve located on the vacuum tube 1102 closes, and the vacuum suction cup 1103 loses its adsorption force on the food. The food gradually falls down with the rotation of the conveyor belt 5, realizing the flipping of the food and ensuring that there are no blind spots in the contact of the food during the cooling and transportation process, thereby improving the cooling and transportation effect of the food.

[0031] Specifically, as the food is conveyed along the anti-jamming guide frame 1106 to the vacuum suction cup 1103, the fine-tuning slider 1110 moves on the fine-tuning rail 1112, and the self-adjusting spring rod 1113 retracts or extends accordingly, thereby preventing excessive squeezing between the food and the turning mechanism 11, which could damage the food and protect it.

[0032] Reference Figure 1 , Figure 2 , Figure 3 and Figure 7 In a preferred embodiment, the cooling box 9 is provided with a circulating sealing mechanism 7 on both sides, and the circulating sealing mechanism 7 includes a docking frame 701. Both sides of the cooling box 9 have inlet and outlet holes. The docking frame 701 is fixedly connected to the inner side wall of the inlet and outlet holes. Two guide vanes 710 are symmetrically distributed on one side of the docking frame 701. The two guide vanes 710 are distributed outwards.

[0033] Reference Figure 3 , Figure 4 and Figure 7 In a preferred embodiment, a pump frame 712 is fixedly connected to the outer wall of the cooling box 9 near the hollow rotating shaft 1101, and a vacuum pump 703 is fixedly connected inside the pump frame 712. A vacuum tube 704 is fixedly connected to the vacuum pump 703 at the vacuum pump end, and one end of the vacuum tube 704 is connected to the shaft hole opened at one end of the hollow rotating shaft 1101 through a bearing.

[0034] Reference Figure 4 and Figure 6 In a preferred embodiment, the outer wall of the hollow rotating shaft 1101 is provided with a circumferential branch hole 1108, and a branch pipe 1107 is fixedly connected inside each branch hole 1108, with one end of the branch pipe 1107 inserted into the interior of an adjacent vacuum tube 1102.

[0035] Reference Figure 6 In a preferred embodiment, air plates 702 are fixedly connected to the inner walls of both sides of the docking frame 701, and airflow elongated holes 705 are equally spaced on opposite sides of the two air plates 702. A pump frame 711 is fixedly connected to the top of the docking frame 701. A circulation pump 707 is fixedly connected inside the pump frame 711. An air extraction pipe 706 is fixedly connected to the air inlet end of the circulation pump 707. One end of the air extraction pipe 706 is inserted into the interior of one of the air plates 702. A circulation pipe 709 is fixedly connected to the air delivery end of the circulation pump 707. The circulation pipe 709 is inserted into the interior of the cooling box 9. An air guide pipe 708 is fixedly connected to the air guide end of the vacuum pump 703. One end of the air guide pipe 708 is inserted into the interior of the other air plate 702.

[0036] Specifically, during the operation of vacuum pump 703, it extracts the cold gas inside the cooling box 9 and delivers it to the air plate 702 through air guide pipe 708. Then, it is ejected through airflow elongated hole 705. Circulation pump 707 is turned on and collects the gas ejected from airflow elongated hole 705, thus forming an air wall. The air wall isolates most of the gas outside the cooling box 9, preventing excessive external gas from entering the cooling box 9 with the food transport and weakening the cooling effect. At the same time, circulation pump 707 reintroduces the collected cold gas into the cooling box 9, reducing cold gas loss.

[0037] Reference Figure 2 , Figure 3 and Figure 8 In a preferred embodiment, the cooling box 9 is provided with an anti-stacking mechanism 12 between the turning mechanism 11 and the circulating sealing mechanism 7, and the anti-stacking mechanism 12 includes an operating plate 1201. The operating plate 1201 is fixedly connected to the inner walls of both sides of the cooling box 9. An adjustment hole 1208 is opened on the top of the operating plate 1201, and two positioning slide rods 1203 are fixedly connected to the inner walls of both sides of the adjustment hole 1208.

[0038] Reference Figures 8-10 In a preferred embodiment, the top of the operating plate 1201 at both ends of the adjustment hole 1208 is fixedly connected to end blocks 1202, and hydraulic cylinders 1206 are fixedly connected to opposite sides of the two end blocks 1202.

A motor plate 1204 is fixedly connected to one side of the sliding bracket 1205, and a drive motor 1212 is fixedly connected to the top of the motor plate 1204. The output shaft of the second drive motor 1212 is fixedly connected to the drive shaft 1213 via a coupling. An outer ring 1218 is fixedly connected to the outer wall of the drive shaft 1213. Two hydraulic cylinders 1214 are symmetrically distributed at the bottom of the outer ring 1218. The output ends of the two hydraulic cylinders 1214 are fixedly connected to the same mating outer ring 1215. An adjusting sleeve 1216 is fixedly connected to the mating outer ring 1215. The adjusting sleeve 1216 is sleeved on the outer wall of the drive shaft 1213. A push rotating plate 1217 is fixedly connected to the bottom of the adjusting sleeve 1216.

[0039] Reference Figure 9 and Figure 10In a preferred embodiment, the top of the operation panel 1201 has a lifting hole, and a lifting baffle 1209 is inserted into the lifting hole. The top of the operation panel 1201 is fixedly connected to the upper frame 1211, and the top of the upper frame 1211 is fixedly connected to two lifting cylinders 1210. The output ends of the two lifting cylinders 1210 are fixedly connected to the top of the upper frame 1211. The side of the upper frame 1211 facing the docking frame 701 has an installation groove 1207. Pressure sensors 1219 are fixedly connected at equal intervals inside the installation groove 1207. The installation groove 1207 is fixedly connected to two telescopic connecting rods 1221 around each pressure sensor 1219. The ends of each pair of adjacent telescopic connecting rods 1221 are fixedly connected to the same pressure plate 1220.

[0040] Specifically, after the food enters the cooling and sealing box 9 along the conveyor belt 5, the second drive motor 1212 is started. The second drive motor 1212 drives the rotating plate 1217 to rotate. The first hydraulic cylinder 1206 drives the rotating plate 1217 to move back and forth, thereby flattening the stacked food and preventing the cooling effect from being reduced due to stacking. At the same time, the flattened food is transported to the lifting baffle 1209 along the conveyor belt 5. When a specified number of pressure sensors 1219 reach a specified value, the lifting cylinder 1210 moves the lifting baffle 1209 upward to sort the food, ensuring that the flipping mechanism 11 can flip a batch of food in a single operation, thus improving the efficiency of food flipping.

[0041] Reference Figure 1 and Figure 2 In a preferred embodiment, a conveyor motor 2 is fixedly connected to one side of one of the shaft plates 1, and the output shaft of the conveyor motor 2 is connected to one end of the transmission roller 3 via a coupling.

[0042] A cooling food conveying method, using a cooling food conveying device as described above, includes the following steps: Step 1: Place the food on the conveyor belt 5. The conveyor motor 2 drives the conveyor roller 3 to rotate, thereby moving the conveyor belt 5. The food enters the cooling box 9 along with the conveyor belt 5. The circulating refrigeration mechanism 4 refrigerates the inside of the cooling box 9. Step 2: After the food enters the cooling box 9 along the conveyor belt 5, start the second drive motor 1212. The second drive motor 1212 drives the rotating plate 1217 to rotate. Adjust the first hydraulic cylinder 1206 to drive the rotating plate 1217 to move back and forth, thereby flattening the stacked food and preventing the cooling effect from being reduced due to stacking. At the same time, the flattened food is transported to the lifting baffle 1209 along the conveyor belt 5. When a specified number of pressure sensors 1219 reach a specified value, the lifting cylinder 1210 moves the lifting baffle 1209 upward to realize the sorting of food. Step 3: After being spread and arranged, the food moves along the conveyor belt 5 to below the flipping mechanism 11. The food moves along the anti-jamming guide frame 1106 to below the corresponding vacuum suction cup 1103. The vacuum pump 703 is in operation, and the vacuum pumps 703 on the vacuum tube 1102 perform vacuum adsorption on the food below. The drive motor 1104 drives the hollow rotating shaft 1101 to rotate. When the food is passively rotated 120°, the contact point between the food and the conveyor belt 5 moves along the conveyor belt 5, so that the food presents a 60° angle after being flipped. The solenoid valve on the vacuum tube 1102 closes, and the vacuum suction cup 1103 loses its adsorption force on the food. The food gradually falls down with the rotation of the conveyor belt 5, realizing the flipping of the food. The food is flipped twice in the entire conveying process. After the two flips, the food is removed from the cooling and sealing box 9 along the conveyor belt 5, completing the cooling and conveying.

10. A method for conveying cooled food, using a cooled food conveying device as described in claim 9, characterized in that, Includes the following steps: Step 1: Place the food on the conveyor belt (5), and the conveyor motor (2) drives the conveyor roller (3) to rotate, thereby moving the conveyor belt (5). The food enters the cooling box (9) along with the conveyor belt (5), and the circulating refrigeration mechanism (4) refrigerates the inside of the cooling box (9). Step 2: After the food enters the cooling box (9) along the conveyor belt (5), start the second drive motor (1212). The second drive motor (1212) drives the push plate (1217) to rotate. Adjust the first hydraulic cylinder (1206) to drive the push plate (1217) to move back and forth, thereby flattening the stacked food and preventing the cooling effect from being reduced due to stacking.

When the food is passively rotated 120°, the contact point between the food and the conveyor belt (5) moves along the conveyor belt (5), so that the food presents a 60° angle after flipping. The solenoid valve on the vacuum tube (1102) is closed, and the vacuum suction cup (1103) loses its suction force on the food. The food gradually falls down with the rotation of the conveyor belt (5), realizing the flipping of the food. The food is flipped twice in the entire conveying process. After the two flips, the food is removed from the cooling and sealing box (9) along the conveyor belt (5).
