Description

Technical Field

[0001] The utility model relates to an empty pallet folding and positioning device, belonging to the field of guarantee machinery. Background Art

[0002] After the material pallet transports the materials, it needs to be uniformly stored and sorted so as to be sent back to the packaging area of the goods for reuse. At present, the folding of the material pallet is mainly carried out by a forklift through the operation of the forklift operator. However, because the forklift cannot move horizontally, and the self-weight of some nylon pallets is relatively large and the stacking height is relatively high, it is impossible to conveniently stack the pallets accurately. The pallets placed in a staggered manner are not only prone to unstable stacking, but also have a low space utilization rate during transportation. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the technical problems in the prior art and provide an empty pallet folding and positioning device.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] An empty pallet folding and positioning device; comprising:

[0006] A pallet placement frame, which includes support columns arranged on the left and right sides. Between the middle parts of the support columns, there is a pallet placement partition. Below the pallet placement partition corresponding to the pallet placement frame, there is an equipment cavity, and above the pallet placement partition corresponding to the pallet placement frame, there is a storage cavity;

[0007] A folding mechanism, which is arranged in the equipment cavity. The folding mechanism includes a main support beam fixed between the support columns. On the main support beam, two groups of mirror-symmetrically arranged support rods are rotatably connected. The support rods are driven by a swing motor. The support rods are of a rectangular closed structure. On the extended ends of the support rods, there are fixed rollers. The rotating ends of the support rods are rotatably connected into the main support beam; in the middle of the support beam, there is a winding groove, and in the winding groove, there is a winding roller rotatably connected. The winding roller is driven by a winding motor. A folding belt is arranged between the winding roller and the fixed roller.

[0008] As a further improvement of the utility model, the winding roller includes winding plates rotatably connected to both ends of the winding groove. On the symmetry axis of the two groups of winding plates, two groups of reversing rods are mirror-symmetrically arranged. The end of the folding belt is fixed to the winding plate and is reversed around the reversing rod.

[0009] As a further improvement of the utility model, the pallet placement partition includes a pallet support frame. In the middle of the pallet support frame, there is a pallet inlay groove. On the side wall of the pallet inlay groove, there are two groups of pallet positioning plates for fixing the pallet.

[0010] As a further improvement of the utility model, the support rod includes two groups of telescopic parts for connecting the protruding end and the rotating end, and the telescopic part includes a group of telescopic sleeves; two groups of cable winches are arranged on the top of the supporting column, and the cable winches are connected with lifting steel cables, and the ends of the lifting steel cables are fixed to the protruding ends of the support rods.

[0011] As a further improvement of the utility model, the gathering belt is made of Oxford cloth.

[0012] The beneficial effects of the utility model are:

[0013] 1. The utility model uses two sets of retractable retracting belts to achieve left and right support and positioning of the pallet during the placement of the pallet. After the pallet is placed, the pallet can be accurately arranged by tightening the retracting belts to ensure the accuracy of pallet stacking. After the retracting belts are tightened, the pallet can be conveniently bundled.

[0014] 2. The winding roller uses a winding plate and a reversing rod instead of a large-diameter integrated structure, which can reduce the deadweight of the entire winding roller and allow the winding plate and the reversing rod to have a certain elastic deformation ability to prevent the gathering belt from being too tight and tearing.

[0015] 3. The pallet support frame can accurately position and fix the bottom pallet, so that the upper pallet can be aligned accordingly.

[0016] 4. The lifting cables and telescopic sleeves can make the mechanism adapt to pallets with different stacking heights.

[0017] 5. Oxford cloth is wear-resistant and pull-resistant. BRIEF DESCRIPTION OF THE DRAWINGS
