Description

Technical Field

[0001] The invention relates to the technical field of food processing, and in particular to a device capable of conveying vegetables at multiple stations. Background Art

[0002] At present, the preparation and production of vegetables has gradually entered the stage of automated production. For example, in the process of processing mustard greens into pickled mustard greens, it is necessary to wash, desalt, dehydrate, mix, fry and other processes. The transportation between different processes is also achieved through conveyor belts. In order to improve the versatility and convenience of the equipment, the conveyor belt should preferably be able to meet the function of allocating mustard greens to different positions. For this multi-station transportation demand, a telescopic conveyor belt is a better choice. It can adjust the length of the conveyor belt so that the mustard greens can be transported to different processes.

[0003] The application announcement number is CN116495408A, which discloses a telescopic belt conveyor control system, method and device. Combined with its specification and drawings, the main body of the telescopic belt conveyor is composed of a first transmission mechanism, a third transmission mechanism and a second transmission mechanism, which are successively reduced in volume and are successively connected in a socket manner. The first transmission mechanism has the largest volume and is fixedly arranged on a base, and the base can be arranged on an assembly plane. The third transmission mechanism has the second largest volume and can be nested inside the first transmission mechanism and extend or retract from the inside of the first transmission mechanism under control. The second transmission mechanism has the smallest volume and can be nested inside the third transmission mechanism and extend or retract from the inside of the third transmission mechanism under control. Through the extension and retraction of the transmission mechanism, the telescopic belt conveyor can realize the increase or decrease of the transmission surface length. However, this scheme can only meet the requirements for the transmission distance during logistics transportation, that is, its conveying angle cannot be changed, and only the conveying length changes. However, during the transportation of mustard, it is sometimes necessary to change the conveying angle to meet its transportation to different processes. Therefore, this structural design brings inconvenience to production. Summary of the invention

The first tensioning roller 62 is arranged at the left end of the top of the second supporting frame 3, and the second tensioning roller 63 is arranged at the right end of the top of the second supporting frame 3 and its two sides are connected to the supporting rollers 65. It should be noted that the winding method of the first conveyor belt 7 is to wind around the first tensioning roller 62, the third roller 53, the fourth roller 54, the second roller 52, the first roller 51 and the second tensioning roller 63 and then reconnect to the first tensioning roller 62, and the surface of the first conveyor belt 7 is connected with a plurality of inclined first material discharge guide plates 71, and the surface of the lifting fuselage 22 close to the first material discharge guide plate 71 is also provided with an inclined second material discharge guide plate 27, and the first material discharge guide plate 71 and the second material discharge guide plate 71 are connected to each other. The setting of 27 is to facilitate the mustard transported by the second conveyor belt 24 to fall exactly onto the surface of the first conveyor belt 7. The second support frame 3 and the tensioning support plate 61 are provided with a plurality of roller support plates 57. The ends of the first tensioning roller 62, the second tensioning roller 63, the first roller 51, the second roller 52, the third roller 53 and the fourth roller 54 that need to be hinged are connected to the roller support plate 57. The surface of the roller support plate 57 at the end of the second roller 52 is also provided with an adjusting screw 58 for adjusting the height, wherein rotating the adjusting screw 58 can control the height of the roller support plate 57 at the end of the second roller 52, thereby realizing the adjustment of the tension of the entire first conveyor belt 7.After being set up in this way, when the telescopic adjustment position is needed, the telescopic adjustment mechanism 8 will drive the rectangular tooth plate 64 to slide and adjust the position. During the sliding process, the rectangular tooth plate 64 supports the roller 65 to roll relative to the profile inside the second support frame 3, and the rectangular tooth plate 64 also drives each tensioning support plate 61 to move at the same time.

[0021] In this embodiment, in this embodiment, a telescopic adjustment mechanism 8 for driving the tensioning mechanism 6 to slide is provided on both sides of the second support frame 3, and the telescopic adjustment mechanism 8 includes a telescopic support box 82, a worm 83, a worm wheel 85, a second gear 84, a driving shaft 86, a fourth reducer 87 and a fourth driving motor 81. A telescopic support plate 31 is extended outward from one side of the second support frame 3, and telescopic support boxes 82 are provided on both sides of the surface of the telescopic support plate 31. A worm 83 is rotatably connected to the interior of each of the telescopic support boxes 82, and a second gear 8 is connected to the top of each of the worm 83. 4. Each of the second gears 84 is connected to the tooth groove on the rectangular tooth plate 64, and the surface transmission of each of the worm 83 is connected to a worm wheel 85. Adjacent worm wheels 85 are connected by a driving shaft 86, and one end of the driving shaft 86 is connected to a fourth reducer 87. The fourth reducer 87 is arranged on the side of the telescopic support box 82. The shaft of the fourth drive motor 81 is connected to the fourth reducer 87. Two sensors 9 are also arranged on the side of the second support frame 3. The sensors 9 can monitor the movement changes of the rectangular tooth plate 64, wherein the sensors 9 can adopt linear Hall effect sensors. Linear Hall effect sensors monitor position changes by measuring the changes in the magnetic field generated when a magnet moves above the sensor. This configuration can provide a linear output, making the monitoring of position changes more accurate and easy. After such setting, the two sensors 9 represent the extended length of the first conveyor belt 7 with two gears. Whenever the worker starts the first gear, the shaft of the fourth drive motor 81 can drive the drive shaft 86 to rotate through the fourth reducer 87. During the rotation of the drive shaft 86, the worm gear 85 inside each telescopic support box 82 can be driven to rotate at the same time. During the rotation of each worm gear 85, the worm 83 can be driven to rotate. During the rotation of each worm gear 85, the second gear 84 can be driven to rotate through the tooth grooves on the rectangular tooth plate 64. The rectangular tooth plate 64 starts to slide. When the sliding distance of the rectangular tooth plate 64 reaches the set value of the first sensor 9, the fourth drive motor 81 will be turned off. Similarly, when the first conveyor belt 7 is further extended and retracted, the fourth drive motor 81 will also be turned off when the other sensor 9 reaches the set value.

[0022] Working principle and use method of the present invention: First, when the shaft of the second drive motor 26 rotates, it can drive the lifting roller 23 to rotate through the second reducer 25. When the lifting rollers 23 at both ends rotate, they can drive the second conveyor belt 24 to produce a reciprocating movement, so that the mustard transported from the outside can be lifted and transported by the second conveyor belt 24 until it falls to the surface of the first conveyor belt 7; then the two sensors 9 represent the extended length of the first conveyor belt 7 with two gears. Whenever the worker starts the first gear, the shaft of the fourth drive motor 81 can drive the driving shaft 86 to rotate through the fourth reducer 87. During the rotation of the driving shaft 86, it can simultaneously drive the worm gear 85 inside each telescopic support box 82 to rotate. During the rotation of each worm gear 85, it will drive the worm 83 to rotate. During the rotation of each worm gear 83, it can drive the second gear 84 to rotate. The second gear 84 will drive the rectangular tooth plate 64 to start sliding through the tooth grooves on the rectangular tooth plate 64. During the sliding process, the rectangular tooth plate 64 The support roller 65 will roll relative to the profile inside the second support frame 3, and the rectangular toothed plate 64 will also drive each tensioning support plate 61 to move simultaneously. During the movement, each tensioning support plate 61 will simultaneously drive the first tensioning roller 62 and the second tensioning roller 63 to change position. The distance between the left end of each tensioning support plate 61 and the left end of the second support frame 3 will continue to increase, but at this time, the positions of the first roller 51, the second roller 52, the third roller 53 and the fourth roller 54 will not change, and these will rotate relative to the inside of the roller support plate 57 to play a supporting and guiding role. Since the first tensioning roller 62 and the second tensioning roller 63 have changed their positions to the left, and the distance between the left end of the tensioning support plate 61 and the left end of the second support frame 3 has increased, the area of ​​the first conveyor belt 7 relative to the surface of the second support frame 3 will continue to increase, and the entire conveying mechanism will realize the function of telescopic conveying distance.

[0023] If the angle of the support frame 3 needs to be adjusted, the rotation shaft of the first drive motor 41 drives the first gear 43 to rotate through the first reducer 42. During the rotation process of the first gear 43, the angle of the entire first drive motor 41 and the first reducer 42 changes under the guiding action of the arc-shaped toothed plate 15. At this time, the angle of the left end of the entire second support frame 3 will also be driven to change at the same time. Since the right end of the second support frame 3 supports the rotation shaft and is connected to the inside of the shaft support column 14, only the left end of the support frame 3 produces an angle change during the rotation process. Moreover, during the angle change of the support frame 3, the universal wheel 44 also slides on the surface of the arc-shaped support plate 13, playing a supporting and guiding role. Finally, after reaching the appropriate position, the third drive motor 56 will drive the first roller 51 to rotate through the third reducer 55, and the first roller 51 will drive the entire first conveyor belt 7 to start reciprocating motion, thereby transporting the mustard on the surface of the first conveyor belt 7.
