[0024] In addition, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present utility model, the meaning of "plurality" is more than two, unless otherwise clearly and specifically limited.

[0025] like Figure 1-4 As shown, the utility model provides a preform box packing machine, which is arranged between a first belt conveyor 10 and a second belt conveyor 20. A plurality of preform transfer plates arranged at intervals are placed on the first belt conveyor 10, and a plurality of preforms are placed on each of the preform transfer plates. A plurality of boxes arranged at intervals are placed on the second belt conveyor 20. The above contents are all prior art, and the specific structure will not be repeated here.

[0026] The utility model comprises a base 30 , an electric turntable 31 , a guide shaft 40 , a lifting mechanism 50 and an adsorption mechanism 60 .

[0027] The base 30 is located between the first belt conveyor 10 and the second belt conveyor 20 , and the electric turntable 31 is disposed on the top of the base 30 and is electrically connected to an external control cabinet.

[0028] The guide shaft 40 is arranged in the longitudinal direction, the lower end of the guide shaft 40 is fixedly connected to the top of the electric turntable 31, and the upper end of the guide shaft 40 is fixedly mounted with a top plate 41. The axis center line of the electric turntable 31 is collinear with the axis center line of the guide shaft 40.

[0029] The lifting mechanism 50 includes a lifting plate 51 and a cylinder 52. The lifting plate 51 is disposed on the guide shaft 40 in a transverse direction and is slidably connected to the guide shaft 40. The cylinder 52 is disposed in a longitudinal direction, the cylinder body of the cylinder 52 is fixedly connected to the top plate 41, the piston rod of the cylinder 52 passes through the top plate 41 and is fixedly connected to the lifting plate 51, and the cylinder 52 is electrically connected to an external control cabinet for controlling the lifting plate 51 to move up and down.

[0030] The suction mechanism 60 is disposed on the first side of the lifting plate 51 , and is used for suctioning the preform.

[0031] In the initial state, the cylinder 52 is in a contracted state.

[0032] The specific working process is:

[0033] First, the external control cabinet controls the cylinder 52 to start, and the piston rod of the cylinder 52 extends to drive the lifting plate 51 to move downward until the adsorption mechanism 60 contacts the preforms on the preform transfer plate, and the adsorption mechanism 60 starts to adsorb all the preforms on the preform transfer plate at the same time.

[0034] Then, the external control cabinet controls the piston rod of the air cylinder 52 to retract, and the lifting plate 51 will move upward. At this time, the preform will be separated from the preform transfer plate and taken away, and will be adsorbed in the air.

[0035] Next, the external control cabinet controls the electric turntable 31 to rotate 180°, and the sucked preforms will move to the top of the second belt conveyor 20. The external control cabinet controls the piston rod of the air cylinder 52 to extend, and the lifting plate 51 will move downward until the bottom of the preforms touches the bottom of the inner wall of the box, and the suction mechanism 60 is closed, and the preforms are automatically placed in the box. Compared with manual boxing, the placement of the preforms is more orderly and the boxing efficiency is higher.

[0036] Finally, the external control cabinet controls the various components of the utility model to reset, and prepares to continue the next packing work.

[0037] In one embodiment, a guide rail is fixedly mounted on the bottom of the lifting plate 51 .

[0038] The adsorption mechanism 60 includes a negative pressure pump 61 and a plurality of sliders 62. The negative pressure pump 61 is fixedly mounted on the lifting plate 51 and electrically connected to the external control cabinet. The plurality of sliders 62 are arranged at intervals on the guide rail and are all slidably connected to the guide rail. A connecting groove 63 extending in the transverse direction is provided inside the slider 62, and the connecting groove 63 is connected to the negative pressure port of the negative pressure pump 61 through a pipe 66. A plurality of negative pressure holes 64 connected to the connecting groove 63 are provided at the bottom of the slider 62. A locking screw 65 is provided on the slider 62, and the locking screw 65 is used to lock the slider 62 on the lifting plate 51.

[0039] When the external control cabinet controls the piston rod of the air cylinder 52 to extend and the slider 62 moves to the vicinity of the preform transfer plate, the external control cabinet controls the negative pressure pump 61 to start, and under the action of the pipeline 66 and the connecting groove 63, negative pressure is formed at the negative pressure holes 64, so that all the preforms on the preform transfer plate are respectively adsorbed at the multiple negative pressure holes 64.

[0040] When the external control cabinet controls the piston rod of the air cylinder 52 to extend and the bottom of the preform contacts the bottom of the inner wall of the box, the external control cabinet controls the negative pressure pump 61 to close, and the preform is automatically placed in the box.

[0041] The adsorption mechanism 60 has a simple structure, is easy to manufacture and use, and has better stability during operation.

[0042] In one embodiment, the threaded end of the locking screw 65 passes through the slider 62 and contacts the lifting plate 51 , and the locking screw 65 is threadedly connected to the slider 62 .

[0043] The spacing between adjacent preforms on preform transfer boards of different specifications is different. Therefore, in order to adapt to preform transfer boards of different specifications, the staff can first loosen the locking screw 65, move the slider 62 to a suitable position, and then tighten the locking nut, so that the spacing between adjacent sliders 62 can be adjusted to adapt to preform transfer boards of different specifications, thereby improving the adaptability of the utility model.

[0044] In one embodiment, a rubber pad 67 is fixedly mounted on the end surface of the threaded end of the locking screw 65. When the locking nut is tightened, the rubber pad 67 can increase the friction between the locking nut and the lifting plate 51, further preventing the slider 62 from moving, and improving the stability of the utility model.

[0045] In one embodiment, there are two adsorption mechanisms 60 , and the two adsorption mechanisms 60 are respectively disposed on both sides of the lifting plate 51 .

[0046] In this way, when one of the suction mechanisms 60 is sucking the preforms on the preform transfer plate, the other suction mechanism 60 can simultaneously put the sucked preforms into the box, and the two mechanisms operate alternately, further improving the packing efficiency of the utility model.

[0047] In one embodiment, there are scale lines 53 on the side wall of the lifting plate 51 to facilitate the staff to accurately adjust the distance between adjacent sliders 62.

[0048] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is defined by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model.

[0049] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
