A first support is fixedly provided at the bottom of the first sliding plate 55. The nut of the first lead screw pair is fixed on the first support. The front section of the lead screw 73 of the first lead screw pair is supported on the frame through the first pedestal bearing. The rear end of the lead screw 73 of the first lead screw pair is fixedly connected to the front output shaft 71 of the double-output shaft motor 7.

[0040] A first sprocket is fixedly arranged on the front end of the lead screw 73 of the first lead screw pair, and a second sprocket is fixedly arranged on the front end of the lead screw 76 of the second lead screw pair. The front side chain 70 is wound around the first sprocket and the second sprocket to form a front side chain drive; A third sprocket 741 is fixedly arranged on the rear end of the lead screw 74 of the third lead screw pair, and a fourth sprocket 781 is fixedly arranged on the rear end of the lead screw 78 of the fourth lead screw pair. The rear side chain 79 is wound around the third sprocket 741 and the fourth sprocket 781 to form a rear side chain drive.

[0041] A front side tensioning wheel adjusting mechanism for tensioning and adjusting the front side chain 70 is arranged on the frame 1; A rear side tensioning wheel adjusting mechanism for tensioning and adjusting the rear side chain 79 is arranged on the frame 1. Both the front side tensioning wheel adjusting mechanism and the rear side tensioning wheel adjusting mechanism adopt the tensioning form of the tensioning wheel 710. Using the tensioning wheel to tension the chain drive is a common means, so the front side tensioning wheel adjusting mechanism and the rear side tensioning wheel adjusting mechanism will not be elaborated here.

[0042] A space for installing and operating a conveying device for goods or pallet groups after transportation and stacking is left between the bottom surfaces of each shaping door 3, the front side shaping door 5, the rear side shaping door 6 and the bottom of the frame 1. In this embodiment, the four-sided shaping machine is usually installed at the conveying device, and at this time, the conveying device passes through the space left between the bottom surfaces of each shaping door 3, the front side shaping door 5, the rear side shaping door 6 and the bottom of the frame 1.

[0043] A first proximity switch 81 and a second proximity switch 82 are arranged on the frame 1 at any one of the four sliding plates, namely the first sliding plate 55, the second sliding plate 57, the third sliding plate 65 and the fourth sliding plate 67. As Figure 1 and Figure 2 shown, in this embodiment, the first proximity switch 81 and the second proximity switch 82 are arranged at the first sliding plate 55. Of course, it is also possible to arrange the first proximity switch 81 and the second proximity switch 82 at other sliding plates.

[0044] For convenience of description, here, taking the example of setting the first proximity switch 81 and the second proximity switch 82 at the first sliding plate 55, the first proximity switch 81 is located at the outermost displacement position set when the first sliding plate 55 slides outwards, and this position is the set maximum opening displacement position when the front shaping door 5 opens outwards. When the front shaping door 5 opens outwards to the set maximum opening displacement position, for the goods or pallet group that can be allowed to enter the rack 1, regardless of whether there is skew or stack collapse, the longest length of its front and rear outer contours does not exceed the distance between the front shaping door 5 and the rear shaping door 6 in this state.

[0045] Among them, the second proximity switch 82 is located at the innermost displacement position set when the first sliding plate 55 slides inwards, and this position is the set maximum closing displacement position when the front shaping door 5 closes inwards. When the front shaping door 5 closes inwards to the set maximum closing displacement position, the goods or pallet group located in the rack 1, under the action of the front shaping door 5 and the rear shaping door 6, its front side and rear side are restored to the neatly stacked state again.

[0046] The four electric cylinders 4 in the above-mentioned first shaping device, the double-output shaft motor 7 in the second shaping device, the first proximity switch 81 and the second proximity switch 82 are all connected to the control system to achieve automatic control.

[0047] When the four shaping doors 3 all open outwards synchronously, and after the front shaping door 5 and the rear shaping door 6 open outwards to the set maximum opening displacement position, the goods or pallet group to be shaped is sent into the rack 1 through the conveying device. At this time, the periphery of the goods or pallet group to be shaped is surrounded by the four shaping doors 3, the front shaping door 5 and the rear shaping door 6. Then, the control device controls the four electric cylinders 4 and the double-output shaft motor 7 to make the four shaping doors 3 all close inwards synchronously, and the front shaping door 5 and the rear shaping door 6 close inwards to the set maximum closing displacement position. At this time, under the joint action of the four shaping doors 3, the front shaping door 5 and the rear shaping door 6, the front side, rear side, left side and right side of the goods or pallet group located in the rack 1 are shaped, and the goods or pallet group in the rack 1 is restored to the neatly stacked state again.

[0048] The four-sided shaping machine adopting the above structure can realize automatic shaping, reduce labor intensity and cost, has high working efficiency, good shaping effect, and can adapt to the shaping operations of goods and pallet groups of various specifications.
