DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figures 1 to 4 A translation mechanism includes a first plate body 100, a second plate body 200 capable of moving along the X direction is slidably connected to the first plate body 100, a third plate body 300 capable of moving along the X direction is slidably connected to the second plate body 200, a fourth plate body 400 capable of moving along the X direction is slidably connected to the third plate body 300, and a conveying mechanism is installed on the fourth plate body 400 for conveying objects.

[0028] The first driving assembly is installed on the first plate body 100. Specifically, a support block 140 is provided on one side of the first plate body 100 facing the second plate body 200, and a first screw rod 111 and a second screw rod 121 are installed on the support block 140. A first connecting member 110 is provided on the first screw rod 111, and the first connecting member 110 can be driven to move by the rotation of the first screw rod 111, and the first connecting member 110 is connected to the second plate body 200. A second connecting member 120 is provided on the second screw rod 121, and the rotation of the second screw rod 121 can drive the movement of the second connecting member 120. An opening 210 is provided on the second plate body 200, and the second connecting member 120 passes through the opening 210 to connect to the third plate body 300.

[0029] The same end of the first screw rod 111 and the second screw rod 121 are connected to the first gear 112 and the second gear 122 respectively. The first motor 130 is installed on the first plate body 100, and the output end of the first motor 130 is connected to the third gear 131. The third gear 131 is meshed with the first gear 112 and the second gear 122 at the same time, so that the first motor 130 can drive the first screw rod 111 and the second screw rod 121 to rotate at the same time, so that the first connecting member 110 and the second connecting member 120 move at the same time. The first connecting member 110 drives the second plate body 200 to move, and the second connecting member 120 drives the third plate body 300 to move on the second plate body 200. The movement of the second plate body 200 superimposed on the movement of the third plate body 300 can accelerate the movement of the fourth plate body 400 and the conveying mechanism installed on the fourth plate body 400, thereby improving the efficiency of palletizing.

[0030] The transmission ratio between the third gear 131 and the second gear 122 is twice the transmission ratio between the third gear 131 and the first gear 112. Through the cooperation of the first gear 112, the second gear 122 and the third gear 131, the moving speed of the second connecting member 120 can be twice the moving speed of the first connecting member 110, that is, when the first plate body 100 moves 100mm, the second plate body 200 moves 200mm, and the combined movement of the two is 300mm, which can achieve three times the movement stroke relative to the movement of the single first plate body 100.

[0031] A second motor 410 is installed on the fourth plate body 400, and the output end of the second motor 410 is connected to the fourth gear 420. A rack 310 meshing with the fourth gear 420 is provided on the surface of the third plate body 300 facing the fourth plate body 400, so that the second motor 410 can drive the fourth plate body 400 to move on the third plate body 300 to adjust the position of the conveying mechanism.

[0032] A transition assembly 500 is installed on the top of the first plate body 100. The transition assembly 500 includes a bracket 510 installed on the first plate body 100. The bracket 510 extends to the top of the third plate body 300. A mounting port 511 is provided on the bracket 510. A roller 520 is embedded in the mounting port 511. The articles transported from the upstream of the translation mechanism to the translation mechanism are transported from the first plate body 100 to the third plate body 300 through the roller 520, so that the articles can move across the first plate body 100, the second plate body 200 and the third plate body 300 to the top of the fourth plate body 400 and can be carried by the conveying mechanism, thereby avoiding the large span between the first plate body 100, the second plate body 200 and the third plate body 300 due to the thickness of their own structures, which affects the normal transportation of the articles.

[0033] Meanwhile, a mounting seat 512 is provided on the bracket 510, and a support member 530 is installed in the mounting seat 512. The support member 530 is a universal ball. Two groups of support members 530 are provided, one group contacts the top of the second plate body 200, and the other group contacts the top of the third plate body 300, thereby supporting the bracket 510. When the second plate body 200 and the third plate body 300 move, the support member 530 rolls on the top of the second plate body 200 and the third plate body 300, thereby ensuring the stability of the bracket 510.

[0034] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
