Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to bundling and packaging equipment for multi-layer plastic plates. Background Art

[0002] Multilayer plastic sheets are materials made by stacking and pressing multiple layers of plastics through a specific process. This structure can provide better physical and chemical properties than single-layer plastic sheets, such as better strength, rigidity, impact resistance and heat resistance. They are commonly used in construction, decoration, billboards, noise barriers and various manufacturing industries. Depending on the application requirements, multilayer plastic sheets can contain different types of plastic materials, such as polycarbonate, ABS, PVC, etc. In order to facilitate the transportation and storage of multilayer plastic sheets, multiple multilayer plastic sheets need to be stacked and bundled together. Therefore, baling and packaging equipment is needed for bundling and packaging in the production process of multilayer plastic sheets.

[0003] The patent with the publication number CN117002786A discloses a plate alignment and bundling device, including a bundling machine, a pair of connecting devices, a pair of alignment devices, a pair of extrusion devices and a synchronous controller; an operating panel is provided on the top surface of the bundling machine, and the connecting devices are detachably installed at the two ends of the front side of the operating panel, and the connecting devices are provided with a positioning frame located on the surface of the operating panel, and a positioning groove is provided in the positioning frame along the length direction of the stacked plates; the alignment devices are detachably installed in the two positioning grooves and can move in the positioning grooves; the extrusion devices are installed on the two pushing mechanisms; the synchronous controller controls each device to perform alignment, extrusion and bundling operations in a preset order. The present invention can use the alignment device to align the length side and width side of the stacked plates, and use the extrusion device to extrude, and use the bundling machine to tighten, weld and cut the binding belt, so that the stacked plates are neatly bundled, the bundling process is semi-automatic, the work efficiency is high, and the labor of the operator is reduced.

[0004] In the specific use of the above-mentioned prior art, the staff needs to stack the plates on the operation panel in the length direction, and stack the front end of the plates close to the right angle formed by the long alignment plate and the wide alignment plate. Then the operator pushes the rear end of the plates and uses the wide alignment plate to align the width side of the plates. Then the synchronous controller controls the two first electric push rods to run forward at the same time, and uses the long alignment plate to push the two side surfaces of the length of the plates at the same time to align the length side of the plates. The above operation can indeed align the positions of multiple stacked plates, but the staff needs to align the multiple plates with the long alignment plate and the wide alignment plate in turn, and then push the multiple plates multiple times. There are many manual operations in this part, which will affect the bundling efficiency of the plates. Moreover, after the multiple plates are stacked and bundled, they need to be rotated 90° to bundle the other two sides of the multiple plates. In this way, the staff needs to readjust the positions of the two alignment devices. The single bundling of plates requires repeated adjustment of the positions of the two alignment devices, which will seriously affect the bundling efficiency of the plates. In view of this, we propose a bundling and packaging device for multi-layer plastic plates. Utility Model Content

To center align the plastic sheets, the staff only needs to stack multiple multi-layer plastic sheets on the workbench of the strapping machine body, and then start the alignment component to center align the multiple stacked multi-layer plastic sheets, ensuring that the strapping belt can be strapped in the middle of the multiple stacked multi-layer plastic sheets. When it is necessary to turn to the multiple stacked multi-layer plastic sheets, the alignment component works in the reverse direction to release the positioning of the multi-layer plastic sheets. After the staff rotates the multi-layer plastic sheets 90°, the alignment component can be started again to center align the multiple stacked multi-layer plastic sheets that have been strapped once, which is conducive to the second strapping operation and improves the efficiency of strapping and packaging.

[0010] Preferably, a servo motor is provided on the left side of the U-shaped fixed plate, and the output shaft of the servo motor is coaxially connected to the left end of the bidirectional screw rod.

[0018] 1. The bundling and packaging equipment for multi-layer plastic sheets drives two moving blocks to move synchronously through a bidirectional screw rod, so that the two moving blocks respectively drive two secondary alignment parts to move synchronously.

When it is necessary to turn to the multiple stacked multi-layer plastic sheets, the alignment component works in the reverse direction to release the positioning of the multi-layer plastic sheets. After the staff rotates the multi-layer plastic sheets 90°, the alignment component can be started again to align the multiple stacked multi-layer plastic sheets that have been strapped once in the center, which is beneficial to the second strapping operation and improves the efficiency of strapping and packaging.
