The bottom end of the push rod 1104 is fixedly connected with a rubber block 1103 extending to the outside of the vacuum negative pressure suction plate 4. The slide frame 7 is used to slide on the slide rail frame 2 The sliding of the surface allows the vacuum negative pressure suction plate 4 to move to one side of the top of the first conveyor rack 6 or the second conveyor rack 8, and then the pneumatic telescopic rod 3 works to realize the up and down sliding of the vacuum negative pressure suction plate 4, and then the external vacuum pump and other equipment generate negative pressure inside the negative pressure chamber 12, so that the bottom end of the vacuum negative pressure suction plate 4 can firmly adsorb the plastic container, and then through the above cooperation, multiple plastic containers can be stacked one by one on one side of the top of the second conveyor rack 8, and then they can be packaged by the packaging machine body 9, thereby realizing its automatic stacking and stacking packaging action.

[0032] Example 2

[0033] On the basis of Example 1, a preferred embodiment of the plastic container rapid stacking packaging device provided by the utility model is as follows: Figures 1 to 5 As shown: the centering component 1 includes a centering frame 101, which is fixedly connected to the upper ends of both sides of the slide rail frame 2, and the inner wall of the centering frame 101 is rotatably connected with a positive and negative threaded rod 107, one end of the positive and negative threaded rod 107 is fixedly connected with a turning handle 105 extending to the outside of the centering frame 101, and both ends of the surface of the positive and negative threaded rod 107 are threadedly connected with threaded blocks 106, and the bottom end of the threaded block 106 is fixedly connected to a connecting frame 102 extending to the outside of the centering frame 101, and the bottom end of the connecting frame 102 is fixedly connected with a centering plate 104, and the positive and negative threaded rods 107 are rotated by rotating the turning handle 105, so that the centering plate 104 can slide to a distance therebetween that is slightly larger than the width of the plastic container, so that the plastic container can be located on the transverse center axis of the first conveying frame 6 and the second conveying frame 8 after passing through the centering plate 104, so as to avoid conveying deviation and cause subsequent stacking or packaging errors.

[0034] In this embodiment, the cross-section of the connecting frame 102 is H-shaped, and the bottom end of the connecting frame 102 and the top end of the center plate 104 are welded into an integrated structure. The welding between the H-shaped connecting frame 102 and the center plate 104 is used to improve the structural strength of the connection between the two.

[0035] In this embodiment, the inner wall of the centering plate 104 is rotatably connected with rotating rollers 103 at equal intervals. The diameter of the cross section of the rotating rollers 103 is larger than the width inside the centering plate 104. The rotating rotating rollers 103 are used to reduce the friction between the plastic container and the inner wall of the centering plate 104, so that the plastic container can pass through the centering plate 104 more smoothly.

[0036] In this embodiment, a sliding structure is formed between the threaded block 106 and the interior of the center frame 101. The cross-sections of the center frame 101 and the threaded block 106 are inverted convex. The inverted convex center frame 101 and threaded block 106 are used to prevent the threaded block 106 from rotating with the rotation of the forward and reverse threaded rods 107, thereby allowing the threaded block 106 to move more smoothly.

[0037] In addition, the conveyor belt surfaces at the upper ends of the first conveyor rack 6 and the second conveyor rack 8 are provided with anti-skid grooves 5 at equal intervals, and the shape of the anti-skid grooves 5 in a top view is an inverted V shape. The inverted V-shaped anti-skid grooves 5 are utilized to increase the friction force of contact between the plastic containers and the conveyor belts at the upper ends of the first conveyor rack 6 and the second conveyor rack 8, thereby improving the anti-skid stability of the plastic containers during transportation.

[0038] The working principle and use process of the utility model are as follows: first, the connecting pipe 10 is connected with an external vacuum pump or other equipment, and then the positive and negative threaded rods 107 are driven to rotate by rotating the rotating handle 105, and the threads of the positive and negative threaded rods 107 and the threaded block 106 are matched, so that the threaded block 106 slides and drives the connecting frame 102 to slide, and then drives the centering plate 104 to slide until the distance between them is slightly larger than the width of the plastic container, so that the plastic container can be located on the transverse center axis of the first conveying frame 6 and the second conveying frame 8 after passing through the centering plate 104, so as to avoid conveying deviation and causing subsequent stacking or packaging errors, and at the same time, the rotating roller 103 is used to reduce the friction between the plastic container and the inner wall of the centering plate 104, so that the plastic container can pass through the centering plate 104 more smoothly;

[0039] Then the anti-slip groove 5 works to move the plastic container slide rail frame 2, and then the sliding frame 7 slides on the surface of the sliding rail frame 2 to the top side of the first conveying frame 6, and then the pneumatic telescopic rod 3 is started to drive the vacuum negative pressure suction plate 4 to descend. At this time, the rubber block 1103 will first contact the surface of the plastic container, so that the top rod 1104 rises and drives the installation slide plate 1105 to slide and compress the reset spring 1107 until it completely enters the negative pressure chamber 12. After that, an external vacuum pump and other equipment generates negative pressure inside the negative pressure chamber 12, and this negative pressure is much greater than the elastic force of the reset spring 1107, which can cause the opening at the bottom of the negative pressure chamber 12 to generate suction, which sucks the plastic container, and then the pneumatic telescopic rod 3 is started to make the vacuum negative pressure suction plate 4 rise and drive the plastic container to rise, and then the sliding frame 7 slides to the second conveying The top side of the rack 8 is activated, and the pneumatic telescopic rod 3 is started to lower the vacuum negative pressure suction plate 4. Then the external vacuum pump is turned off, and the plastic container loses suction and falls to the top side of the second conveyor rack 8. At this time, the elastic force of the reset spring 1107 is used to make the mounting slide 1105 descend to drive the top rod 1104 to descend, so that the rubber block 1103 can make it easier for the plastic container to be separated from the bottom end of the vacuum negative pressure suction plate 4, avoiding the inconvenience of separation caused by too close contact between the plastic container and the bottom end of the vacuum negative pressure suction plate 4, and then repeat the above operation, stack multiple plastic containers one by one to a suitable height, and then use the upper end conveyor belt of the second conveyor rack 8 to transport the stacked plastic containers to the bottom of the packaging machine body 9, and then the packaging machine body 9 can be used for packaging.

[0040] The above are only preferred embodiments of the present invention and are 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.
