DETAILED DESCRIPTION

[0024] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0025] Example:

[0026] Reference Figure 1 and Figure 2As shown, the present embodiment provides a logistics box unpacking device, which is mainly used for the process of unpacking the sealing strip of the logistics carton and transferring the internal goods. During the unpacking process, since the logistics cartons may be of different sizes, it is impossible to accurately and effectively keep the sealing ring of the logistics box in the center position, and it is easy to cause damage to the carton body during the unpacking process. In order to solve this kind of problem, a logistics box unpacking device in the present embodiment includes an unpacking frame 11 and a working chamber 32 opened on one side of the unpacking frame 11, and a logistics box slides in the working chamber 32, and it is characterized in that a correction mechanism for aligning the logistics box and an unpacking machine for unpacking the logistics box are provided in the working chamber 32. The correction mechanism comprises a correction slide bar 12 and a slide door 22 which slide in the working chamber 32, the unpacking mechanism comprises an unpacking base 25 which slides at the lower side of the slide door 22 and an unpacking component which is arranged on the unpacking base 25 and is used for unpacking the logistics box with a tape, the unpacking base 25 is provided with a power mechanism which drives the unpacking base 25 to move, the correction mechanism is used for correcting the position of the logistics box and triggering the unpacking mechanism to unpack the logistics box; when the logistics box is pushed into the working chamber 32, the sealing strip of the logistics box is not necessarily in the middle, so it is impossible to ensure that the unpacking mechanism can unseal the sealing strip through the unpacking mechanism;

[0027] When correction is needed, the correction mechanism starts to start, so that the two correction slide bars 12 begin to approach each other on the end face of the unpacking frame 11, and then the two correction slide bars 12 continue to approach the logistics box, and then the correction slide bars 12 push the logistics box to the center position, thereby ensuring that the sealing strip of the logistics box can be opened by the unpacking mechanism.

[0028] It should be noted that the power mechanism includes a driving motor fixedly mounted on the unpacking frame 11, and a threaded shaft is driven on one end of the driving motor, and the threaded shaft is threadedly connected to the opening base 25; when the correction mechanism completes the correction, the opening mechanism is triggered to start running, and the power mechanism in the opening base 25 starts to run, thereby driving the opening base 25 to start moving, and then driving the opening assembly to start moving, thereby achieving the purpose of making the opening mechanism start to open the logistics box.

[0029] Reference Figure 1 and Figure 5As shown, the logistics box is prone to detachment and falling during the transfer process. In order to solve this problem, the top surface of the unpacking frame 11 is provided with a rectangular groove 13 opening upward, and the sliding door 22 slides between the end walls of the rectangular groove 13. The sliding door 22 is provided with a storage groove 26 opening upward, and the rear side of the storage groove 26 is through-connected; when the logistics box falls into the storage groove 26, since the storage groove 26 is in the shape of a groove, the logistics box can be restricted by the edge and will not fall, and at the same time, it can smoothly enter the storage groove through the through part of the rear side of the sliding door 22.

[0030] Combination Figures 1 to 5 As shown, after the calibration is completed, the sealing strip needs to be unsealed, and at the same time, the unpacking mechanism should be prevented from causing damage to the logistics box. In the process of transferring goods in the logistics box, the traditional upper side unpacking method makes the method of transferring goods not conducive to transfer when taking out large objects, and it is easy to cause damage to the objects. In order to solve this kind of problem, a half groove is opened on the end surface of the two sliding doors 22 close to each other, and the sliding doors 22 abut against each other to form an unpacking groove 23 that runs through from top to bottom. A telescopic mechanism is provided on the end surface of the sliding doors 22 away from each other, and the telescopic mechanism includes a telescopic rod 20. The telescopic rod 20 is provided on the end surface of the two sliding doors 22. One end of the retractable rod 20 is connected to the unpacking frame 11, and the other end of the telescopic rod 20 is connected to the sliding door 22; when the unpacking is completed, the bottom sealing strip of the logistics box is opened, and the telescopic mechanism starts to operate and starts to retract the telescopic rod 20, thereby driving the telescopic rod 20 to move away continuously, thereby driving the two sliding doors 22 to move away continuously, and the unpacking slot 23 is continuously opened. At this time, the correction slide bar 12 abuts against the outer end of the logistics carton, and the goods on the storage slot 26 can fall onto the unpacking base 25 through the unpacking slot 23, thereby achieving the purpose of directly transferring the goods.

[0031] Reference Figure 1 and Figure 3 as well as Figure 4 , Figure 5As shown, when it is necessary to unseal the bottom tape of the logistics box, it is impossible to unseal it manually. In order to solve this problem, the unseal component includes a spring groove 28 opened on the top surface of the unseal base 25, and the spring groove 28 is opposite to the box opening groove 23. A rotating shaft 30 is fixed between the end walls of the spring groove 28, and an unsealing tip block 27 is rotatably provided on the outer periphery of the rotating shaft 30. One end of the unsealing tip block 27 extends out of the outside, and the protruding end of the unsealing tip block 27 is in a pointed shape; when the unsealing component is needed to unseal, the unsealing base 25 starts to move, thereby driving the unsealing tip block 27 to move until one end surface of the unsealing tip block 27 abuts against the bottom surface of the sliding door 22. At this time, the unsealing The tip block 27 is abutted by the sliding door 22 and starts to drive the rotating shaft 30 to rotate. At this time, the unsealing tip block 27 has not entered the opening groove 23. When the unsealing base 25 continues to move, the unsealing tip block 27 begins to enter a section of the opening groove 23. At this time, the unsealing tip block 27 is no longer abutted by the sliding door 22, and then the unsealing tip block 27 is restored to a normal state under the influence of the deformation of the reset spring 31, and then the unsealing tip block 27 begins to abut against one end face of the sealing strip of the logistics carton. At this time, the unsealing tip block 27 can puncture the sealing strip. At the same time, the movement of the unsealing base 25 drives the unsealing tip block 27 to continue to unseal the sealing strip, so that the lower end of the logistics box is in an unsealed state, thereby ensuring the purpose of unsealing the sealing strip at the bottom of the logistics box.

[0032] It should be noted that spring blocks 29 are respectively fixed on the front and rear end surfaces of the unpacking tip block 27, and a return spring 31 is fixedly connected to the bottom surface of the spring block 29. The other end of the return spring 31 is fixedly connected to the top wall of the spring groove 28, thereby ensuring that when the unpacking tip block 27 is abutted by the sliding door 22, it starts to drive the rotating shaft 30 to rotate, thereby driving the spring block 29 to start rotating, and then causing the return spring 31 to start deforming. When the unpacking tip block 27 is no longer abutted by the sliding door 22, it is affected by the deformation of the return spring 31 and the unpacking tip block 27 returns to a normal state, thereby ensuring that the unpacking tip block is in a vertical upward state when in the unpacking groove 23, thereby ensuring that the unpacking can be carried out effectively.

[0033] At the same time, since the unsealing tip block 27 in this embodiment needs to unseal the sealing strip without affecting the carton, it is necessary to ensure that the length of the unsealing tip block 27 entering the carton during unsealing is limited to a certain extent, so that the unsealing tip block 27 can unseal the sealing strip without affecting the carton.

[0034] Reference Figure 1 and Figure 2 as well as Figure 5As shown, if the running speed of the correction mechanism is too fast, the correction slide bar 12 will cause a certain impact on the logistics box, which will cause damage to the logistics box. At the same time, it is necessary to provide power for the correction mechanism. In order to solve this kind of problem, the two sides of the unpacking frame 11 are semi-cylindrical, and the left and right front end surfaces of the unpacking frame 11 are respectively fixed with fixed bases 24, and two semicircular grooves are provided in the fixed base 24. A power shaft 17 is rotatably connected in the end surface of the semicircular groove. A driving gear 18 is fixed on the outer periphery of the power shaft 17. The driving gear 18 rotates in the semicircular groove. The height of the driving gear 18 is greater than the height of the fixed base 24. Two rotating motors are fixedly installed on the top surface of the unpacking frame 11, and the rotating motor drives the two outer power shafts 17 to rotate. Pulleys are provided on the outer peripheries of the power shafts 17 on the left and right sides, and belts are respectively connected between the pulleys on the left and right sides. When the correction mechanism needs to be started, the rotating motor drives the two outer power shafts 17 to rotate. The rotation of the two outer power shafts 17 drives the rotation of the pulleys, and then drives the movement of the belt, and then drives the two inner power shafts 17 to rotate, thereby achieving the purpose of driving the driving gear 18 to rotate, thereby ensuring that a stable power source is provided for the correction mechanism and that smooth correction can be performed.

[0035] In addition, in order to ensure that the two correction slide bars can slide smoothly, and further to ensure that the sealing strip of the logistics box can always face the box slot 23, in order to solve such problems, the top surfaces of the two fixed bases 24 are respectively fixed with two fan-shaped limiting fan blocks 15, and two abutting and sliding buffer gear rods 14 are slidably provided between the two mutually adjacent limiting fan blocks 15, and the upper end surface of the outer driving gear 18 is meshed with the front end surface of one of the buffer gear rods 14, and the upper end surface of the inner driving gear 18 is meshed with the front end surface of the other buffer gear rod 14. The two limiting fan blocks 15 can ensure that the buffer gear rod 14 can always ensure movement in one direction, thereby achieving the purpose of making the correction slide bar 12 slide smoothly.

[0036] It should be noted that a limiting groove is provided in the buffer gear rod 14, and a center shaft 19 is fixed on the top surface of the fixed base 24. The center shaft 19 slides in two limiting grooves, and the center shaft 19 is located between the two power shafts 17; while the buffer gear rod 14 slides, it ensures that the center shaft 19 always slides in the limiting groove, further ensuring that the correction slide 12 can slide smoothly.

[0037] At the same time, due to the cross-sliding of the buffer gear rods, a certain angle difference will be caused. In order to avoid the influence of this difference on the correction sliding, and to make the buffering effect of the correction sliding on the logistics box more obvious, and to ensure that the logistics box will not be damaged, a guide groove is provided in the opposite end face of the correction slide bar 12, and two guide sliding blocks are slidingly provided in the guide groove, and a rotating cavity is provided in the guide sliding block, and a rotating shaft is fixed between the end walls of the rotating cavity. The ends of the buffer gear rods 14 on both sides that are close to each other are rotatably connected to the outer periphery of the rotating shaft, and buffer pads 21 are fixed on the end faces of the correction slide bars 12 that are facing each other, and the end faces of the buffer pads 21 that are close to each other abut against the end faces of the logistics box. When the buffer gear rod moves, it will continuously drive the two guide sliding blocks to slide in the guide groove, thereby achieving the purpose of ensuring that the correction slide bar is always stable. At the same time, the buffer pad 21 can ensure that the impact on the logistics box is minimized, thereby achieving the purpose of protecting the logistics box.

[0038] The above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the scope of protection required by the present invention.
