When the mounting plate 2 needs to be adjusted up and down, the motor 31 is started, the output shaft of the motor 31 drives the screw 34 to rotate, and the threaded barrel 35 moves up and down by cooperating with the screw 34, so that the threaded barrel 35 drives the mounting plate 2 to move up and down, thereby realizing the function of adjusting the position of the mounting plate 2; The clamping assembly 4 includes a clamping plate 41. The clamping assembly 4 is a symmetrical structure. The two clamping plates 41 are slidably installed on the mounting plate 2. A mounting groove 9 is opened in the mounting plate 2. A slider 42 is slidably connected to the mounting groove 9. The slider 42 is fixedly connected to the clamping plate 41. A spring 43 is connected between the slider 42 and the inner wall of the mounting groove 9. A pressure plate 44 is slidably installed on the mounting plate 2. A connecting rod 45 is fixedly connected to the bottom of the pressure plate 44. A slide plate 46 is slidably connected to the mounting groove 9. The slide plate 46 is fixedly connected to the connecting rod 45. A spring 47 is connected between the slide plate 46 and the mounting groove 9. The two ends of the slide plate 46 are fixedly connected to the limiting blocks 48. Slots 49 are opened on the two slide plates 42. The position of the slots 49 matches the limiting blocks 48. The initial position of the mounting plate 2 is not at the bottom, and at this time it is not released from the inclined plate 53 of the recovery assembly 5. When the goods are placed on the pressure plate 44, the goods squeeze and drive the pressure plate 44 to slide downward, and the pressure plate 44 drives the slide plate 2 46 to slide downward through the connecting rod 45, and the slide plate 2 46 drives the limit blocks 48 on both sides to move downward, and the initial position of the limit block 48 is located above the slot 49, and the spring 1 46 is initially in a compressed state. At the same time, the limit block 48 initially contacts with the slide plate 1 42 and restricts its sliding.

[0017] The restoration component 5 includes a touch rod 51. The restoration component 5 is a symmetrical structure. Two slide grooves 52 are opened at the bottom of the mounting plate 2, and the two slide grooves 52 are connected to the mounting groove 9. The touch rod 51 is fixedly connected to the bottom of the slide plate 42. The two touch rods 51 are slidably connected to the two slide grooves 52 respectively. Two inclined plates 53 are fixedly connected to the base 1. The positions of the two inclined plates 53 match the two touch rods 51. When the device transports the goods to the designated position, the driving motor 31 causes the rotating lifting component 3 to drive the mounting plate 2 to descend to the lowest point. During this process, the two slide bars 51 are released from the two inclined plates 53 and under the action of the inclined plates 53, the two slide bars 51 slide to both sides respectively, and at the same time drive the two slide plates 42 to slide to both sides, and the two slide plates 42 drive the two clamping plates 41 to slide to both sides to restore their original positions.

A detection element 11 for detecting the height of the goods is installed on the mounting plate 2, and a motor two is installed on the mounting plate 2, one of the rotating shafts 64 is fixedly connected to the output shaft of the motor two, and the detection element 11 is connected to the power supply of the motor two. When the detection element 11 detects that the goods are higher, the motor two is triggered to run, and the output shaft of the motor two drives the rotating shaft 2 64 to rotate, and the rotating shaft 2 64 drives the gear one 65 to rotate. Through the cooperation of the two gears one 65, the two rotating shafts 2 64 rotate at the same time, and the two rotating shafts 2 64 drive the two rotating shafts 1 62 to rotate through the belt 63 respectively, as shown in FIG. Figure 5 As shown, the two rotating shafts 1 62 respectively drive the two protective plates 61 to rotate to the specified positions to achieve the protection of higher goods. During this movement, the rack 1 67 contacts the baffle 12 and slides under the force of the baffle 12. The sliding of the rack 1 67 drives the gear 2 66 to rotate, and the gear 2 66 drives the rack 2 68 to slide outward. The rack 2 68 drives the pad 69 to slide outward, so that when the protective component 6 is triggered, the pad 69 pops out to further protect the goods.

[0024] When the mounting plate 2 needs to be adjusted up and down, the motor 31 is started, and the output shaft of the motor 31 drives the screw 34 to rotate, and the threaded cylinder 35 moves up and down by cooperating with the screw 34, so that the threaded cylinder 35 drives the mounting plate 2 to move up and down, thereby realizing the function of adjusting the position of the mounting plate 2. When the goods are placed on the pressure plate 44, the goods squeeze and drive the pressure plate 44 to slide downward, and the pressure plate 44 drives the slide plate 2 46 to slide downward through the connecting rod 45, and the slide plate 2 46 drives the limit blocks 48 on both sides to move downward. After the limit blocks 48 slide downward, the limit blocks 48 enter the slots 49 to cancel the interference limit on the slide plate 1 42, and the two slide plates 1 42 slide toward the center respectively under the elastic force of the two springs 1 43, and at the same time drive the two clamping plates 41 to slide toward the center, correcting the position of the goods while fixing the goods, thereby avoiding the situation that the mounting plate is unevenly stressed due to uneven placement of the goods, causing the mounting plate 2 to tilt. After reaching the specified position, the motor 1 31 is driven to make the rotating lifting assembly 3 drive the mounting plate 2 to descend to the lowest point. In this process, the two sliding bars 51 and the two inclined plates 53 are released and under the action of the inclined plates 53, the two sliding bars 51 slide to both sides respectively, and at the same time drive the two sliding plates 1 42 to slide to both sides, and the two sliding plates 1 42 drive the two clamping plates 41 to slide to both sides to restore to their original positions. At this time, the goods are taken down, and the sliding plate 2 46 slides upward under the elastic force of the spring 2 47, and at the same time drives the limit blocks 48 on both sides to slide upward, and limits the two sliding plates 1 42 again, thereby realizing the recovery of the clamping assembly 4, which is convenient for the subsequent use of the device. When the detection element 11 detects that the goods are higher, the motor 2 is triggered to run, and the output shaft of the motor 2 drives the rotating shaft 2 64 to rotate, and the rotating shaft 2 64 drives the gear 1 65 to rotate. Through the cooperation of the two gears 1 65, the two rotating shafts 2 64 rotate at the same time, and the two rotating shafts 2 64 respectively drive the two rotating shafts 1 62 to rotate through the belt 63, as shown in FIG. Figure 5 As shown, the two rotating shafts 1 62 respectively drive the two protective plates 61 to rotate to the specified positions to achieve the protection of higher goods. During this movement, the rack 1 67 contacts the baffle 12 and slides under the force of the baffle 12. The sliding of the rack 1 67 drives the gear 2 66 to rotate, and the gear 2 66 drives the rack 2 68 to slide outward. The rack 2 68 drives the pad 69 to slide outward, so that when the protective component 6 is triggered, the pad 69 pops out to further protect the goods.
