Description

Technical Field

[0001] This utility model relates to the field of pallet transportation, and in particular to a transportation device for the production of plastic pallets. Background Technology

[0002] Currently, Chinese utility model patent CN216509997U discloses a transport device for plastic pallet production, including a transport platform and a blocking mechanism. The blocking mechanism is located at the top of the transport platform and includes two stop bars, both of which are fixedly installed at the top of the transport platform. A movable plate is arranged between the two stop bars, with its two sides movably connected to the top of the two stop bars respectively. First bolts are threaded through both sides of the movable plate. A pressure plate is movably arranged at the bottom of the movable plate, and three sets of elastic components are arranged between the movable plate and the pressure plate. This utility model allows multiple plastic pallets to be stacked on the transport platform. The two stop bars can limit and block the sides of the plastic pallets, and the pressure plate, through the elastic components, can exert pressure on the top plastic pallet, positioning the multiple plastic pallets on the transport platform and preventing them from shaking or tipping over, thus improving the protective performance of the plastic pallets during transport.

[0003] While existing transport devices can carry plastic pallets, they also have other problems during use, such as poor limiting effect, the need for pallets to be continuously stacked during placement, difficulty for personnel to load or unload excessively high stacks, and difficulty in passing through height-restricted areas such as doorways, resulting in poor practicality. Furthermore, they lack width adjustment functionality. Due to the varying sizes of plastic pallets, larger pallets will extend beyond the device's exterior after placement, leaving the extended portions unprotected. When the device moves through corners, the extended portions of the pallets are highly susceptible to contact with buildings and wear, leading to poor safety. To address these issues, we propose a transport device for plastic pallet production. Utility Model Content

[0004] The purpose of this invention is to provide a transport device for the production of plastic pallets, which solves the problems of poor limiting effect and lack of width adjustment function of existing transport devices.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a transport device for producing plastic pallets, comprising a frame, a lead screw rotatably connected to the inside of the frame via a bearing, a motor fixedly sleeved at the other end of the lead screw, a movable plate threadedly connected to the surface of the lead screw, a push plate welded to the top of the movable plate, a fixed plate welded to the top of the frame, adjusting plates provided on both the front and back of the frame, connecting plates symmetrically welded to opposite sides of the two adjusting plates, a threaded rod welded to one side of the connecting plate, the other end of the threaded rod penetrating to the outside of the frame and threadedly connected to a fixing nut, and sliding grooves provided on both sides of the frame.

[0006] The above technical solution provides width adjustment, is easy and convenient to operate, avoids wear on the excess part of the pallet, ensures high safety, improves the limiting effect on the pallet, prevents the pallet from falling due to shaking, and is also convenient to pick up and put down the pallet, making it highly practical.

[0007] The present invention is further configured such that: two limiting rods are provided through one side of the movable plate, and both ends of the limiting rods are welded to the inside of the frame.

[0008] By adopting the above technical solution, the moving plate can be limited by the setting of the limiting rod, preventing the moving plate from rotating during left and right movement.

[0009] The present invention is further configured such that a protective cover is bolted to one side of the frame.

[0010] By adopting the above technical solution, the motor can be protected by the protective cover, preventing damage caused by collisions with external objects.

[0011] The present invention is further configured such that: a caster wheel is installed at the bottom of the frame, and a brake pad is installed on the surface of the caster wheel.

[0012] By adopting the above technical solution, the installation of casters and brake pads makes it easy for personnel to push the device.

[0013] The present invention is further configured such that rubber pads are adhered to the opposite sides of the push plate and the fixed plate.

[0014] By adopting the above technical solution, the rubber pad can protect the plastic pallet and prevent the push plate from scratching the surface of the plastic pallet when clamping.

[0015] The present invention is further configured such that both the threaded rod and the fixing nut are made of stainless steel.

[0016] Using the above technical solution, the threaded rod and the fixing nut have the characteristics of high strength, low density and excellent corrosion resistance.

[0017] The present invention is further configured such that the top of the adjustment plate is flush with the top of the frame.

[0018] By adopting the above technical solution, the excess portion of the pallet can be supported, thus improving the stability of pallet placement.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. This utility model involves first erecting the tray onto the frame, then moving the tray to the center, and then loosening the fixing nut with a tool. Once loosened, the fixing nut releases the fixing of the connecting plate. Then, a person can grasp the adjusting plate and pull it outward until it exceeds the tray. After the adjusting plate is pulled out to the appropriate distance, the fixing nut is tightened again. This method has a width adjustment function, is simple and convenient to operate, avoids wear on the part of the tray that exceeds the limit, and has high safety.

[0021] 2. This utility model involves starting the motor after all the trays are placed. The motor drives the lead screw to rotate, and the lead screw, in conjunction with the limiting rod, drives the moving plate to the left. As the moving plate moves to the left, it drives the pushing plate to push the tray. The pushing plate, in conjunction with the fixing plate, clamps the tray, which improves the limiting effect on the tray and prevents the tray from falling due to shaking. It is also more convenient to pick up and put down the tray, making it highly practical. Attached Figure Description
