When purchasing fruit, people are paying more and more attention to the quality of flavor, taste and freshness. How to accurately and comprehensively judge the internal quality of fruit has become a focus of attention for both consumers and sellers. Before fruit is produced, packaged and sold, testing systems are usually used to test the internal pulp. Fruits are batched according to different sizes of pulp or the quality of pulp. However, during the testing process, it is difficult to achieve the positioning and transportation of fruit trays, which may cause the fruit trays to be not accurately transported to the corresponding testing positions, thus affecting the final testing results and making them less practical.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4 This utility model provides a pallet positioning and transportation mechanism, including symmetrically arranged conveyor frames 1, with symmetrically arranged support components 2 at the bottom of both sides of the conveyor frames 1, and fixed components 3 at both ends of the conveyor frames 1. One fixed component 3 has an active roller 4 in the middle, and the other fixed component 3 has an adjustable passive roller 5 in the middle. The active roller 4 and the passive roller 5 are connected by a belt 6. One side of the conveyor frame 1 is connected to the active roller 4 on the same side and has a drive component 7. Several position sensors 8 are arranged on the side of the conveyor frame 1. By starting the motor 73 in the drive component 7, the active rollers 4 at the ends of the two conveyor frames 1 are driven to rotate synchronously, so that the active roller 4, belt 6 and passive roller 5 are driven to move the fruit pallet 13 on the top of the two conveyor frames 1. The position of the fruit pallet 13 on the top of the conveyor frame 1 is detected by the position sensors 8. When the fruit pallet 13 is transported to a specific position, the motor 73 is stopped. The fruit in the fruit pallet 13 is detected and processed by an external detection system, thereby improving the detection effect of the equipment.

[0021] Specifically, there are three position sensors 8, which are used to gradually decelerate the fruit tray 13 during transportation to prevent the fruit tray 13 from slipping on top of the belt 6. When the fruit tray 13 contacts the first position sensor 8 near the drive roller 4, the speed of the belt 6 is reduced to 1 / 4 of its original speed; when it contacts the next position sensor 8, the belt 6 decelerates to 1 / 8 of its original speed; when it contacts the last position sensor 8, the belt 6 decelerates to 0, thus transporting the fruit tray 13 to a specific detection position, facilitating the detection of the fruit in the fruit tray 13 by an external detection system and improving the final detection effect.

[0022] like Figure 3 As shown, specifically, the support assembly 2 includes support columns 21 symmetrically arranged at the bottom of the conveyor frame 1. The top of the support column 21 is fixedly connected to the conveyor frame 1 through a connecting block 22, and the bottom of the support column 21 is connected to an adjustable foot 23. The conveyor frame 1 is fixedly connected to the support column 21 through the connecting block 22, thereby supporting the equipment through four support columns 21. At the same time, the appropriate length of the support column 21 can be selected according to the imaging distance with the external detection system to improve the detection effect of the equipment. During the installation process, the adjustable foot 23 can also further fine-tune the support column 21, improving the practicality of the equipment.

[0023] Specifically, the fixing component 3 includes fixing plates 31 symmetrically arranged at the ends of the conveyor frame 1. One side of the fixing plate 31 is connected to the drive roller 4, and the middle of the fixing plate 31 on the other side is provided with an adjustment groove 32. Fixing shafts 33 that are rotatably connected to the passive roller 5 are installed in the adjustment grooves 32 on both sides. By using the fixing plates 31 symmetrically arranged at both ends of the conveyor frame 1, the drive roller 4 and the fixing shafts 33 are installed. Furthermore, by guiding the fixing shafts 33 along the adjustment grooves 32, the tension of the belt 6 is adjusted, so that the belt 6 is always in a taut state, thereby improving the conveying effect of the belt 6 on the fruit tray 13.

[0024] Specifically, the two conveyor frames 1 on both sides are connected by several parallel shafts 9. By inserting four parallel shafts 9 in the middle of the two conveyor frames 1, the parallelism of the two conveyor frames 1 is ensured, and the two belts 6 drive the fruit tray 13 on the top to move synchronously, thereby improving the transportation effect.

[0025] Specifically, the two conveyor frames 1 on both sides are connected to a control cabinet 10 on the side closest to the passive roller 5, and the control cabinet 10 is used to control the operation of this equipment.

[0026] Specifically, several mounting frames 11 are installed on the side of the conveyor frame 1, and a barrier frame 12 is connected to the top of the mounting frame 11. By setting the barrier frame 12 on the side of the conveyor frame 1, the fruit tray 13 can move in a straight line on the top of the belt 6, so as to transport the fruit tray 13 to the special fruit inspection station and improve the subsequent inspection effect.

[0027] like Figure 4 As shown, specifically, the drive assembly 7 includes a transmission wheel 71 on the outer circular wall of one side of the active roller 4, a motor base 72 on the same side of the conveyor frame 1, a motor 73 mounted on the motor base 72, a main pulley 74 at the output end of the motor 73, the main pulley 74 being connected to the transmission wheel 71 via a second belt 75, and the active rollers 4 on both sides being connected via a coupling 76. By starting the motor 73, the main pulley 74 is driven to rotate synchronously, and then the active rollers 4 on both sides are driven to rotate via the second belt 75 and the transmission wheel 71. Then, the fruit tray 13 is driven to move on the top of the conveyor frame 1 via the first belt 6 and the passive roller 5.

[0028] The working principle of this utility model is as follows: When in use, the motor 73 is started, which drives the active rollers 4 at the ends of the conveyor frames 1 on both sides to rotate synchronously. This causes the active rollers 4, belt 6, and passive rollers 5 to work together to drive the fruit tray 13 to move on top of the conveyor frames 1 on both sides. The position of the fruit tray 13 on top of the conveyor frame 1 is detected by the position sensor 8. When the fruit tray 13 is transported to a specific position, the motor 73 is stopped. The fruit in the fruit tray 13 is then detected and processed by an external detection system, thereby improving the detection effect of the equipment.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
