[0017] Technical effects and advantages of the present invention:

[0018] 1. The present invention arranges structures such as a support plate, an interception plate, and a first elastic member so that the stacked PE bottles cannot pass normally from under the interception plate and are intercepted by the interception plate. The bottles will impact the interception plate under the driving action of the conveyor belt of the feeding section.

[0019] 2. The present invention arranges structures such as a slider, a half gear and a second rack. When tightly overlapped PE bottles cause a feed blockage, the two gears can drive the rotating rod to rotate by meshing with the corresponding first rack. When the rotating rod rotates, it can drive the meshing of the half gear and the second rack to drive the slider to further slide inside the second chute and compress a plurality of second elastic members to store energy. When the half gear loses meshing with the second rack, the slider is released and quickly slides out of the second chute under the action of the plurality of second elastic members, thereby striking the blocked PE bottle, unblocking the blocked PE bottle, preventing the PE bottle from being blocked, and separating the tightly overlapped PE bottles by striking, thereby further improving the overlapping separation effect, and further improving the picking efficiency and picking accuracy.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1

[0032] refer to Figure 1 - Figure 3 A PE bottle flakes incoming material quality inspection and selection system according to an embodiment of the present invention comprises a quality inspection device 1, a packing unpacking device 2 and a selection device 3 which are sequentially arranged along the material conveying direction. The selection device 3 comprises a mounting frame 31. A vibrating screen 32 and a sorting machine 33 are sequentially arranged above the mounting frame 31 along the material conveying direction. The vibrating screen 32 is used to separate impurities in the disassembled PE bottles. The sorting machine 33 is used to select the colors of the PE bottles. The vibrating screen 32 and the sorting machine 33 are prior arts and will not be described in detail herein.

[0033] refer to Figure 3 The quality inspection device 1 includes a first conveyor line 11, which can be a roller conveyor line. Microwave moisture meters 12 for detecting moisture content of bottle bricks are installed on both sides of the first conveyor line 11. The microwave moisture meter 12 includes a transmitter and a receiver. The microwave signal is transmitted to the bottle bricks through the transmitter, and the receiver is responsible for receiving the microwave signal passed through the bottle bricks. The roller conveyor line and the microwave moisture meter 12 are existing technologies and will not be described in detail here.

[0034] refer to Figure 3The unpacking device 2 includes a second conveyor line 21, which can be a belt conveyor line. An unpacking machine 22 for disassembling bottle bricks is installed at one end of the second conveyor line 21 away from the quality inspection device 1. A baffle 23 is installed above the second conveyor line 21 to prevent the bottle bricks from scattering randomly when they are disassembled. The belt conveyor line and the unpacking machine 22 are existing technologies and will not be described in detail here.

[0035] refer to Figure 2 A third feeding device 5 is installed between the unpacking device 2 and the picking device 3. The third feeding device 5 can be a screw conveyor. The third feeding device 5 is used to convey the PE bottles unpacked by the unpacking machine 22 to the vibrating screening machine 32. The screw conveyor is a prior art and will not be described in detail here.

[0036] In actual use, the bottle bricks that are weighed for sampling quality inspection are placed on the first conveyor line 11, and the bottle bricks are conveyed to the second conveyor line 21 through the first conveyor line 11. During the conveying process, the microwave moisture meter 12 can detect the water content in the bottle bricks. The bottle bricks conveyed to the second conveyor line 21 will be conveyed in the direction of the unpacking machine 22, and the bottle bricks will be broken up by the unpacking machine 22. The broken PE bottles will fall into the third feeding device 5 and be conveyed to the vibration screening machine 32. The vibration screening machine 32 separates some impurities in the PE bottles by vibration and conveys the PE bottles to the sorting machine 33. The sorting machine 33 selects the PE bottles according to color and type through visual inspection, thereby realizing automated quality inspection and selection work, reducing manual intervention, and improving the quality inspection and selection accuracy and efficiency of PE bottles.

[0037] Embodiment 2

[0038] There may be a phenomenon of mixing and overlapping of PE bottles transported to the sorting machine 33. The mixing and overlapping of PE bottles will cause the sorting machine 33 to need more time to distinguish and is prone to selection errors, resulting in the need for more manpower for selection in the later stage, which increases production costs and affects the accuracy and processing efficiency of PE bottle quality inspection and selection. Therefore, this embodiment improves the device described in the above embodiment.

[0039] refer to Figure 1 and Figure 2 The sorting machine 33 includes a feeding part 331 and a picking part 332. An overlapping processing device 4 is arranged above the feeding part 331. The overlapping processing device 4 is used to intercept the mixed and overlapping PE bottles before the sorting machine 33 picks the PE bottles, and cooperate with the feeding part 331 to separate the overlapping PE bottles.

[0040] refer to Figure 4 - Fig. 9The overlapping processing device 4 includes two symmetrically arranged support plates 41, and the two support plates 41 are fixedly connected to the top of the feeding part 331 and are respectively located on both sides of the feeding part 331. The two support plates 41 are provided with first slide grooves 42 along the feeding direction of the feeding part 331. The two first slide grooves 42 are commonly slidably connected with an intercepting plate 43 located between the two support plates 41. The two first slide grooves 42 are each provided with a first elastic member 44, one end of the two first elastic members 44 is connected to the side of the intercepting plate 43 away from the vibrating screening machine 32, and the other ends of the two first elastic members 44 are respectively connected to the inner wall of the corresponding first slide groove 42.

[0041] In actual use, the PE bottles transported from the vibrating screening machine 32 to the sorting machine 33 will fall onto the conveyor belt of the feeding part 331. At this time, the PE bottles can pass normally from under the interception plate 43. When the PE bottles falling from the vibrating screening machine 32 are too concentrated or too many, the PE bottles falling onto the conveyor belt of the feeding part 331 may appear mixed and stacked. At this time, the height of the stacked PE bottles will change, and they will not be able to pass normally from under the interception plate 43 and will be intercepted by the interception plate 43. After stacking, the PE bottles will impact the interception plate 43 under the driving action of the conveyor belt of the feeding part 331. On the one hand, the PE bottles that are mixed and overlapped loosely are separated under the action of the impact, so that they can pass under the interception plate 43. On the other hand, the PE bottles that fall onto the conveyor belt of the feeding part 331 can pass through in an orderly manner, which can prevent the PE bottles from being transported too densely and improve the detection and selection accuracy of the selection part 332.

[0042] It should be noted that when the intercepting plate 43 is impacted, the first elastic member 44 can act as a buffer for the intercepting plate 43, thereby reducing the direct force of the intercepting plate 43 on the supporting plate 41, preventing the supporting plate 41 and the feeding part 331 from being subjected to excessive force at the installation position, and reducing the problem of loose installation.

[0043] When the PE bottle is intercepted by the interception plate 43, it will rub against the conveyor belt of the feeding part 331. During the friction, impurities and notes on the bottle body will gradually fall off, which plays a cleaning role, can reduce the interference factors of the selection part 332 when selecting PE bottles, and improve the detection and selection accuracy.

[0044] To sum up, through the arrangement of structures such as the support plate 41, the interception plate 43 and the first elastic member 44, the stacked PE bottles cannot pass normally from under the interception plate 43 and are intercepted by the interception plate 43. They will impact the interception plate 43 under the driving action of the conveyor belt of the feeding part 331. On the one hand, the PE bottles that are mixed and overlapped loosely are separated by the impact so that they can pass under the interception plate 43. On the other hand, the PE bottles that fall onto the conveyor belt of the feeding part 331 can pass through in an orderly manner, which can prevent the PE bottles from being transported too densely and improve the detection and selection accuracy of the selection part 332.

[0045] Embodiment 3

[0046] In actual use, there are cases where the PE bottles separated by the unpacking machine 22 are not completely separated. In this case, the mixed and overlapped PE bottles are relatively tight, and the tightly overlapped PE bottles cannot be separated only by intercepting with the interception plate 43, which can easily cause PE bottle feeding blockage and affect the working efficiency of the sorting machine 33. Therefore, this embodiment improves the device described in the above embodiment.

[0047] refer to Figure 4 - Fig. 9 A second chute 45 is provided at the lower part of the intercepting plate 43 near the vibrating screening machine 32, a slider 46 is slidably connected in the second chute 45, a plurality of second elastic members 47 are evenly connected between the side of the slider 46 away from the vibrating screening machine 32 and the inner wall of the second chute 45, a driving groove 48 is provided inside the intercepting plate 43, and both ends of the intercepting plate 43 located inside the two first chute 42 are provided with rotating grooves 49 connected to the driving groove 48, a rotating rod 410 is rotatably connected inside the driving groove 48, and both ends of the rotating rod 410 are fixed. A gear 411 is fixedly connected, and the two gears 411 are rotatably connected in the corresponding two rotating grooves 49 respectively. The tops of the two first sliding grooves 42 are fixedly embedded with first racks 412 that mesh with the two gears 411. A connecting groove 413 connecting the driving groove 48 and the second sliding groove 45 is opened inside the intercepting plate 43. A half gear 414 is fixedly connected to the outer wall of the rotating rod 410, and the half gear 414 is rotatably connected in the connecting groove 413. A second rack 415 that can mesh with the half gear 414 is fixedly embedded on the top of the sliding block 46.

[0048] In actual use, tightly overlapped PE bottles will gradually cause feeding blockage, and the conveyor belt of the feeding part 331 will drive the blocked PE bottles to push the intercepting plate 43 to slide in the first slide groove 42 and compress the first elastic member 44. During the movement, the intercepting plate 43 can drive the rotating rod 410 to rotate through the engagement of the two gears 411 with the corresponding first rack 412. When the rotating rod 410 rotates, it can drive the half gear 414 to rotate in the connecting groove 413, and drive the slider 46 to further rotate in the second slide groove through the engagement of the half gear 414 with the second rack 415. The inside of the groove 45 slides in a direction away from the vibrating screening machine 32 and compresses multiple second elastic members 47 to store energy. When the half gear 414 loses engagement with the second rack 415, the slider 46 is released and quickly slides out of the second slide groove 45 under the action of multiple second elastic members 47, thereby hitting the blocked PE bottle, clearing the blocked PE bottle, preventing the PE bottle from being blocked, and separating the tightly overlapping PE bottles by hitting, thereby further improving the overlapping separation effect, and further improving the working efficiency and selection accuracy of the sorting machine 33.

[0049] It should be noted that when the blockage is cleared, the first elastic member 44 pushes the intercepting plate 43 back to the initial position, and the half gear 414 will reverse under the driving action of the rotating rod 410. The half gear 414 will contact the second rack 415 during the reversal process. At this time, the half gear 414 will push the second rack 415 and the slider 46 to further extend out of the second slide groove 45 and stretch the second elastic member 47, so that the reversal of the half gear 414 will not affect the meshing of the half gear 414 with the second rack 415 during forward rotation.

[0050] By adjusting the number of teeth of the half gear 414 and the second rack 415 , the force accumulation degree and release timing of the slider 46 can be changed, thereby changing the impact force on the overlapping PE bottles.

[0051] To sum up, through the arrangement of the slider 46, the half gear 414 and the second rack 415 and other structures, when the tightly overlapped PE bottles cause feeding blockage, the two gears 411 can drive the rotating rod 410 to rotate by engaging with the corresponding first rack 412. When the rotating rod 410 rotates, it can drive the engagement of the half gear 414 and the second rack 415 to drive the slider 46 to further slide inside the second slide groove 45 and compress the multiple second elastic members 47 to store energy. When the half gear 414 loses engagement with the second rack 415, the slider 46 is released and quickly slides out of the second slide groove 45 under the action of the multiple second elastic members 47, thereby hitting the blocked PE bottles, unblocking the blocked PE bottles, preventing the PE bottles from being blocked, and separating the tightly overlapped PE bottles by hitting, thereby further improving the overlapping separation effect, and further improving the picking efficiency and picking accuracy.

[0052] Moreover, when the slider 46 quickly slides out of the second slide groove 45 under the action of multiple second elastic members 47 and clears and separates the blocked PE bottles, since the PE bottles are no longer excessively overlapped and piled on one side of the interception plate 43, the pressure applied to one side of the interception plate 43 is reduced, and the interception plate 43 returns to its initial position under the action of the first elastic member 44. During this process, the interception plate 43 can drive the slider 46 to further push the PE bottles to separate from each other, so that the overlapping separation effect of the PE bottles is further improved.

[0053] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
