Specifically, fresh products refer to primary products that have not undergone deep processing such as cooking and making, and are only sold after necessary preservation and simple arrangement on the shelves. Among them, vegetable and meat products need to be transported by conveyor belts before packaging, and different vegetables are transported to different locations for subsequent packaging operations; during the use of existing PU conveyor belts for fresh products, vegetables are usually placed in multiple open boxes on top, and then the boxes are placed on the conveyor belt 2, so that multiple boxes are transported to designated locations in sequence, and by setting up the boxes, a relatively stable space can be provided for the vegetables, which can effectively prevent the vegetables from being physically damaged by collision, extrusion, friction, etc. during transportation, and the boxes can also prevent the products from rolling or sliding during transportation, ensuring that the products can arrive at the designated location intact, but when the boxes arrive at the designated location, they need to be manually removed from the conveyor belt 2, which is relatively labor-intensive, and the multiple boxes removed may be in a messy state, which is not conducive to the classification and identification of the vegetables in the boxes, and thus it is not convenient for the subsequent packaging of the vegetables in the boxes, and confusion is prone to occur, affecting the normal progress of the packaging work;

Therefore, when this embodiment is used, it is used for a batch of square boxes with the same specifications. According to the side length of the box, the electric push rod 11 is started to drive the connecting block 9 to rise and fall, and under the action of the connecting rod 10, multiple limit plates 6 can slide on the adjustment plate 4 at the same time. The angle inside the limit plate 6 is regarded as a corner of the square. Under the action of the four limit plates 6, a square with the same side length as the box is formed, and the preliminary adjustment work can be completed.

Then place the box containing vegetables on the conveyor belt 2. Since the conveyor belt 2 is made of PU material, the conveyor belt 2 can maintain stable performance at a high temperature, is not easy to deform or damage, and has excellent wear resistance, can resist long-term friction and wear, and extend the service life. As the conveyor belt 2 runs, the box moves to the leftmost end of the conveyor belt 2, and after the box is detached from the conveyor belt 2, it will be on the adjustment table 5, and then start the electric push rod 2 18 to drive the connecting plate 24 to rise, so that multiple fitting columns 19 can rise at the same time and pass through the groove of the adjustment table 5 until the upper end surface of the fitting column 19 is higher than the upper end surface of the adjustment table 5, and then start the motor 1 25 to drive the connecting plate 24 to rise. The connecting rod three 37 and the gear 35 on the side rotate, and under the effect of the gear ring 22, multiple connecting rods three 37 and connecting rod two 36 rotate at the same time. When the angle between the connecting rod two 36 and the connecting rod three 37 changes, the sliding rod four 40 can slide in the inner cavity of the sliding sleeve 39, and the multiple displacement blocks 26 move at the same time, so that the multiple fitting columns 19 are close to the center of the adjustment platform 5 at the same time. When the multiple fitting columns 19 are all fitted with the box body, the box body is straightened, and the four sides of the box body are parallel to the four sides of the adjustment platform 5. At this time, the four corners of the box body are just aligned with the inner angle of the limit plate 6, and then the electric push rod three 28 is started to drive the lifting plate 29 to slide and rise on the sliding rod three 27 until the hard tube 20 The suction cup 21 passes through the through hole in the middle of the adjustment table 5, and contacts and fits with the bottom of the box. Then, the vacuum pump 30 is used to extract the air at the suction cup 21, so that the suction cup 21 adsorbs the box, and then the multiple fitting columns 19 are driven away from the box again. Then, under the action of the electric push rod 3 28, the suction cup 21 drives the box to rise. When the upper angle of the box contacts the bottom of the support block 41, the support block 41 is squeezed, causing the support block 41 to slide, and the slide bar 14 slides in the inner cavity of the sleeve 13, and the spring 15 is compressed. When the end face of one side of the support block 41 is flush with the end face of one side of the limit plate 6, the edge of the box fits with the inner side of the limit plate 6, and the box continues to rise. When the box When the lower end surface is higher than the upper end surface of the support block 41, the spring 15 is restored, and the support block 41 is reset, so that the bottom of the box can be supported, thereby realizing the placement of the box. By repeating the above operation, multiple boxes can be stacked and aligned at the edges by squeezing the upper box with the subsequent box, thereby eliminating the process of manually unloading the box from the conveyor belt 2, which is relatively labor-saving. In addition, the multiple boxes taken down are neatly stacked. When packaging, multiple boxes can be taken down in turn to package the vegetables therein, which is convenient for personnel to classify and identify the vegetables in the boxes, and it is not easy to cause packaging confusion, thereby ensuring the smooth progress of the packaging work.

Furthermore, since the box is open at the top, when vegetables are loaded inside the box, the vegetables may lean against the edge of the box and be above the upper end surface of the box. When this happens, if the boxes are stacked, the vegetables will be squeezed between the boxes, which may easily cause damage to the vegetables and affect the quality of the vegetables. Therefore, when the box is on the adjustment table 5 and is straightened, the electric push rod 4 32 is used to drive the push plates 7 on both sides to rise and fall according to the height of the upper end surface of the box, so that the lower end surface of the push plate 7 is flush with the upper end surface of the box, and then the motors 2 34 on both sides are started at the same time to drive the bidirectional threaded rod 38 By rotating, the sliders 33 on the left and right sides can slide simultaneously and approach each other, so that the push plate 7 can approach the middle of the box from the left and right sides. When the lower end surface of the box passes over the upper end surface of the box, the vegetables on the upper end surface of the box that are leaning on it can be pushed to fall down and lay flat until the two push plates 7 fit together. In addition, by moving the two push plates 7 from the left and right sides of the box and approaching each other, the push plates 7 can be prevented from squeezing the vegetables to the edge of the box, causing damage to the vegetables. This can avoid squeezing of the vegetables between the boxes when the boxes are stacked, thereby ensuring the quality of the vegetables and preventing them from being damaged.

Therefore, by utilizing the anti-squeezing stacking mechanism, when multiple boxes containing vegetables are transported to the designated position by the conveyor belt 2, the multiple boxes can be collected and neatly stacked, eliminating the process of manually unloading the boxes from the conveyor belt 2, which is relatively labor-saving. In addition, since the multiple boxes are neatly stacked, when it is necessary to pack the vegetables, the multiple boxes can be taken down in turn to pack the vegetables therein, which is convenient for personnel to classify and identify the vegetables in the boxes, and it is not easy to cause packaging confusion, thereby ensuring the smooth progress of the packaging work. In addition, before the boxes are straightened and moved upward, the push plate 7 can be driven from the left and right sides of the box to the middle of the box. By the way that the lower end surface of the box passes over the upper end surface of the box, the vegetables that are high on the upper end surface of the box due to leaning can be pushed to make them tilt and lie flat and lower than the upper end surface of the box, thereby avoiding the situation that the boxes squeeze the vegetables when they are stacked, thereby ensuring the quality of the vegetables and preventing them from being damaged.

In this embodiment, as shown in FIG. 1 and FIG. 10 , the front and rear ends of the right side of the support frame 1 are rotatably provided with brush rollers 8, the front end of the right side of the support frame 1 is fixedly connected to a motor 3 42, and the output end of the motor 3 42 is fixedly connected to the brush roller 8;

Specifically, when the conveyor belt 2 is running, the motor 3 42 can be started to drive the brush roller 8 to rotate, and the brush roller 8 can be used to form friction with the surface of the conveyor belt 2 to clean the vegetable residues remaining on the surface of the conveyor belt 2, thereby ensuring the cleanliness of the surface of the conveyor belt 2, avoiding the phenomenon of poor operation or blockage of the conveyor belt 2 due to the residual vegetable residues on the surface of the conveyor belt 2, and reducing the odor and dirt in the working area, thereby improving the comfort of the working environment.

Working principle: according to the side length of the box, start the electric push rod 11 to drive the connecting block 9 to rise and fall, and under the action of the connecting rod 10, multiple limit plates 6 can slide on the adjustment plate 4 at the same time, and the angle inside the limit plate 6 is regarded as a corner of the square. Under the action of the four limit plates 6, a square with the same side length of the box is formed, and the preliminary adjustment work can be completed; then the box filled with vegetables is placed on the conveyor belt 2. As the conveyor belt 2 runs, the box moves to the leftmost end of the conveyor belt 2, and after the box is detached from the conveyor belt 2, it will be on the adjustment table 5, and then start the electric push rod 2 18 to drive the connecting plate 24 to rise, so that multiple fitting columns 19 can be raised and lowered at the same time. The gear 35 is rotated by the motor 25, and the connecting rod 37 and the gear 35 on one side are driven to rotate. Under the effect of the gear ring 22, the connecting rods 37 and the connecting rods 23 are rotated at the same time. When the angle between the connecting rods 23 and the connecting rods 37 changes, the sliding rod 40 can slide in the inner cavity of the sliding sleeve 39, and the displacement blocks 26 move at the same time, so that the multiple fitting columns 19 are close to the center of the adjusting platform 5 at the same time. When the multiple fitting columns 19 are fitted with the box body, the box body is straightened, and the four sides of the box body are parallel to the four sides of the adjusting platform 5. At this time, the four corners of the box body are just aligned with the inner angle of the limit plate 6. Then, the electric push rod 3 28 is started to drive the lifting plate 29 to slide and rise on the slide rod 3 27 until the hard tube 20 passes through the through hole in the middle of the adjustment table 5, and the suction cup 21 contacts and fits with the bottom of the box. Then, the vacuum pump 30 is used to extract the air at the suction cup 21, so that the suction cup 21 adsorbs the box, and then the multiple fitting columns 19 are driven away from the box again. Then, under the action of the electric push rod 3 28, the suction cup 21 drives the box to rise. When the upper angle of the box contacts the bottom of the support block 41, the support block 41 will be squeezed, causing the support block 41 to slide, and the slide rod 14 slides in the inner cavity of the sleeve 13. The spring 15 is compressed. When the end face of one side of the support block 41 contacts the side of the limit plate 6 When the end faces are flush, the edge of the box body fits against the inner side of the limit plate 6, and the box body continues to rise. When the lower end face of the box body is higher than the upper end face of the support block 41, the spring 15 recovers and the support block 41 is reset to support the bottom of the box body, thereby realizing the placement of the box body. The above operation can be repeated, and multiple boxes can be stacked and aligned at the edges by squeezing the upper box body by subsequent boxes, thereby eliminating the need for manual unloading of the boxes from the conveyor belt 2, which is more labor-saving. In addition, the multiple boxes taken down are neatly stacked. When packaging, multiple boxes can be taken down one by one to package the vegetables therein, which is convenient for personnel to classify and identify the vegetables in the boxes. The situation that packaging is easily confused is ensured to be carried out smoothly; and, because the box body is open at the top, when vegetables are loaded inside the box body, the vegetables may lean on the edge of the box body and be on the upper end surface of the box body. When this happens, if the boxes are stacked, the vegetables will be squeezed between the boxes, which may easily cause damage to the vegetables and affect the quality of the vegetables. Therefore, when the box body is on the adjustment table 5 and is straightened, according to the height of the upper end surface of the box body, the electric push rod 4 32 is used to drive the push plates 7 on both sides to rise and fall, so that the lower end surface of the push plate 7 is flush with the upper end surface of the box body, and then the motors 2 34 on both sides are started at the same time to drive the two-way threaded rod 3 When the two push plates 7 are in contact with each other, the push plates 7 can prevent the vegetables from being squeezed toward the edge of the box body and causing the vegetables to be damaged. This can prevent the vegetables from being squeezed between the boxes when they are stacked, thereby ensuring the quality of the vegetables and preventing them from being damaged. After being transported to the designated position by the conveyor belt 2, the multiple boxes can be collected and neatly stacked, eliminating the need to manually unload the boxes from the conveyor belt 2, which saves manpower. In addition, since the multiple boxes are neatly stacked, when it is necessary to pack the vegetables, the multiple boxes can be taken down in turn to pack the vegetables therein, which is convenient for personnel to classify and identify the vegetables in the boxes, and it is not easy to cause packaging confusion, thereby ensuring the smooth progress of the packaging work. In addition, before the boxes are straightened and moved upward, the push plate 7 can be driven from the left and right sides of the box to the middle of the box, and the lower end surface of the box can be passed through the upper end surface of the box to The vegetables on the upper end surface of the box body can be pushed to fall down and lie flat and lower than the upper end surface of the box body, so that the vegetables can be avoided from being squeezed between the boxes when the boxes are stacked, thereby ensuring the quality of the vegetables and preventing them from being damaged. When the conveyor belt 2 is running, the brush roller 8 can be driven to rotate by starting the motor 3 42, and the brush roller 8 can be used to form friction with the surface of the conveyor belt 2 to clean the vegetable residues remaining on the surface of the conveyor belt 2, thereby ensuring the cleanliness of the surface of the conveyor belt 2, avoiding the phenomenon of poor operation or blockage of the conveyor belt 2 due to the vegetable residues remaining on the surface of the conveyor belt 2, and reducing the odor and dirt in the working area, thereby improving the comfort of the working environment.
