Description

Technical Field

[0001] This utility model relates to the technical field of material transportation equipment in the printing industry, and in particular to a cardboard transportation pallet for printing plants. Background Technology

[0002] In the printing industry, cardboard, as a crucial raw material or semi-finished product, has a significant impact on product quality and production efficiency during its transportation and storage. Existing cardboard transport pallets typically include a pallet, supporting structure, and simple securing devices, but in practical applications, the following problems urgently need to be addressed:

[0003] 1. Traditional pallets often use external straps or ropes to secure cardboard stacks, requiring manual and repeated adjustments to the tightness. During transportation, vibrations can easily cause the straps to loosen, posing a risk of cardboard slippage. Some built-in fixing structures in the winding devices lack effective limits, making it difficult to maintain stable tension in the fixing straps.

[0004] 2. Printed paperboard is sensitive to environmental humidity. Most existing pallets do not have built-in moisture-proof components. In humid environments, the paperboard is easily deformed, stuck or moldy due to moisture erosion. Especially during long-distance transportation or storage, additional moisture-proof packaging materials are required, which increases costs and makes the operation cumbersome.

[0005] 3. The functional modules such as fixing devices, moisture-proof components, and bottom plate connection structure are independent of each other and lack systematic design, resulting in a bulky overall pallet structure, high maintenance costs, and difficulty in adapting to the transportation needs of different specifications of cardboard. Summary of the Invention

[0006] In view of the technical problems existing in the background art, the present invention provides a new type of cardboard transport pallet for printing plants, which integrates efficient fixing, moisture protection and convenient loading and unloading, so as to meet the professional needs of the printing industry for material transport equipment.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A cardboard transport pallet for a printing plant includes a pallet, a flexible fixing strap, a pull-out plate, and a winding device. The bottom of the pallet is vertically provided with legs, and the flexible fixing strap and the winding device are provided inside the legs. The flexible fixing strap is wound up by the winding device. A clamping plate is inserted into the side of the pallet, and a bottom plate is installed on the upper end of the pallet. When transporting cardboard stacks, they are stacked on the bottom plate and secured by the flexible fixing strap.

[0009] In a preferred embodiment, the pull-out plate is provided with a retaining rail on its side, and a placement groove is provided on the upper end face of the tray. A corresponding sliding groove is provided on the inner side of the placement groove, and the pull-out plate is inserted into the sliding groove through the retaining rails on both sides.

[0010] In a preferred embodiment, a material trough is provided at the upper end of the pull-out plate, and the material trough is filled with a desiccant.

[0011] In a preferred embodiment, a slot is provided at the upper end of the tray, a metal sheet is installed in the slot, and a magnetic strip is provided on the bottom surface of the base plate. The base plate is magnetically connected to the slot through the magnetic strip.

[0012] In the preferred embodiment, ventilation holes are provided on the base plate.

[0013] In a preferred embodiment, a flexible fixing strap is rolled inside one of the support legs, and a strip hole is opened on the side wall of the other support leg. A clamping plate is provided at the end of the flexible fixing strap, and the clamping plate is engaged with the strip hole after passing around the cardboard stack above.

[0014] In a preferred embodiment, the winding device includes a rotating shaft and a knob. The rotating shaft passes vertically through the side wall of the support leg and can rotate freely around its own axis. A knob is provided at one end of the rotating shaft, and the other end of the rotating shaft is perpendicularly connected to the chuck.

[0015] In the preferred embodiment, limit holes are provided on the side walls of the chuck and the support legs, and the locking pin passes through the limit holes to lock and fix the position of the chuck and the rotating shaft.

[0016] A cardboard transport pallet for printing plants, which, in practical use, can achieve the following beneficial effects:

[0017] 1. The efficient and stable fixing system adopts a structural design that combines a built-in winding device with a flexible fixing strap. The flexible fixing strap can be quickly wound up and down by rotating the knob. The tension is locked by using the locking pins passing through the limiting holes of the chuck and the support feet to avoid loosening of the binding due to transportation vibration. The locking structure of the end plate and the strip hole forms a closed loop fixation, which eliminates the need for frequent manual adjustments and significantly improves the reliability and operational efficiency of cardboard stack fixing.

[0018] 2. Integrated moisture-proof protection function: The pull-out panel is connected to the tray via a sliding groove on the rail. The desiccant filled in the material slot can actively absorb moisture inside the tray. Combined with the ventilation hole design of the bottom plate, it forms a "moisture-proof-ventilation" dual protection mechanism, which effectively prevents the cardboard from deforming, sticking or becoming moldy due to abnormal humidity. It is especially suitable for long-distance transportation and storage in humid environments, reducing additional moisture-proof packaging costs.

[0019] 3. The magnetic connection structure of the quick-installation and removal magnetic base plate tray slot and the magnetic strip of the base plate allows for quick installation and removal of the base plate without tools, solving the problem of time-consuming and laborious traditional bolt or clip connections; the high-strength adsorption force of the metal sheet and the magnetic strip ensures that the base plate is stable and does not shift during transportation, while also facilitating the individual replacement or cleaning of the base plate, improving the convenience of pallet maintenance.
