Technical Field

[0002] A plastic pallet welding machine is a device used to connect the various parts of a plastic pallet to form a complete pallet. It mainly achieves a strong bond between materials by heating and pressing to melt the surface of the plastic material and then cooling and solidifying it.

[0003] Chinese Patent Publication No. CN221775296U, published on 20240927, discloses a plastic pallet welding machine. The plastic pallet welding machine includes: an upper worktable on which multiple third clamps capable of holding third pallet plastic parts are mounted; a third driving device capable of driving the upper worktable to move up and down; a first lower worktable on which multiple first clamps capable of holding first pallet plastic parts are fixed; a first driving device capable of driving the first lower worktable to move below the upper worktable; a second lower worktable on which multiple second clamps capable of holding second pallet plastic parts are fixed; a second driving device capable of driving the second lower worktable to move it below the upper worktable; and a fourth driving device capable of moving multiple upper heating plates and multiple lower heating plates to heat between the third pallet plastic parts and the second pallet plastic parts.

[0004] In existing plastic pallet welding machines, pallet components are mostly fixed using molds. However, slight expansion occurs after welding, resulting in uncertain deformation. Therefore, the pallet positioning structure can be further optimized, and a corresponding pallet positioning calibration structure is urgently needed to solve the above problems. Utility Model Content

The tops of side frame one and side frame two are respectively fixedly connected to flat push cylinder one and flat push cylinder two, and the output ends of flat push cylinder one and flat push cylinder two are respectively fixedly connected to limit block one and limit block two. The top of the pallet plate is integrated with a base plate, and the top of the base plate is integrated with an upper support assembly for supporting pallet components.

[0008] Preferably, a lifting cylinder is fixedly connected to the bottom of the pallet, a placement frame is fixedly connected to the output end of the lifting cylinder, and the placement frame is fixedly connected to the push cylinder.

[0009] Preferably, a push cylinder is fixedly connected to the bottom of the pallet, and the output end of the push cylinder is fixedly connected to the bottom of the base plate.

[0010] Preferably, the upper support assembly includes an upper support cylinder fixedly connected to the top of the base plate, and the output end of the upper support cylinder is fixedly connected to an upper support seat.

[0011] Preferably, a limiting frame is fixedly connected to the top of the base plate, and the limiting frame has an L-shaped structure.

[0012] Preferably, a guide rail is fixedly connected to the top of the placement rack, and a slide is fixedly connected to the bottom of the connecting rack, with the slide being slidably connected to the guide rail.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, after the pallet component is placed in the corresponding position on the pallet plate, the upper support cylinder pushes the upper support seat, which in turn pushes the pallet component upward to a specified height. Then, the entire push cylinder is connected via...

[0015] After the pusher moves side frame one and side frame two by the same distance, the pusher cylinder one and pusher cylinder two push the limit block one and limit block two respectively. The limit block one and limit block two are correspondingly engaged with the horizontal outer wall of the pallet component. The traditional mold is replaced by multiple caliable cylinders, which can adapt to the heating deformation of the pallet component and ensure the stable positioning of the pallet component.

[0016] 2. In this application, a lifting cylinder is fixed at the bottom of the pallet. The lifting cylinder can be linked with the push cylinder and the two corresponding flat push cylinders through the placement frame to change the height.

The top of the pallet 2 is integrated with a base plate 11. The top of the base plate 11 is integrated with an upper support assembly for supporting the pallet components.

[0026] After the pallet component is placed in the corresponding position on the pallet plate 2, the upper support cylinder 13 pushes the upper support seat 10, and the upper support seat 10 pushes the pallet component upward to a specified height. Then, the push cylinder 9 pushes the side frame 3 and the side frame 4 to move the same distance through the connecting frame. Then, the horizontal push cylinder 5 and the horizontal push cylinder 7 push the limit block 6 and the limit block 8 respectively. The limit block 6 and the limit block 8 are correspondingly engaged with the horizontal outer wall of the pallet component. The traditional mold is replaced by a set of caliable cylinders, which can adapt to the heating deformation of the pallet component and ensure the stable positioning of the pallet component.

A limit frame 12 is fixedly connected to the top of the base plate 11, and the limit frame 12 has an L-shaped structure, which can be used to limit the horizontal movement of the tray components. A guide rail is fixedly connected to the top of the placement frame 15, and a slide is fixedly connected to the bottom of the connecting frame.

[0030] Working principle: After the pallet component is placed in the corresponding position on the pallet plate 2, the upper support cylinder 13 pushes the upper support seat 10, which in turn pushes the pallet component upward to a specified height. Then, the main push cylinder 9 pushes the side frame 3 and the side frame 4 to move the same distance through the connecting frame. Then, the horizontal push cylinder 5 and the horizontal push cylinder 7 push the limit block 6 and the limit block 8 respectively.
