Because the top of the folding roller is higher than the top of the U-shaped groove, under the traction of the second steel roller, two sides of the blank wire are rapidly folded into the inner part to form the four-folded wire, and the folded finished wire has no sharp edge and is not easy to damage the appearance of agricultural products.
Description
Technical Field
The invention relates to the technical field of plastic machinery, in particular to a plastic embryonic silk folding structure.
Background
The existing plastic woven bag is woven by plastic wires, so that the plastic woven bag is light in weight and low in cost and is widely applied to the field of packaging; the mesh bag silk of the woven bag is generally folded into three-folded silk (the folded edge is on the outer side) by adopting the monofilament or flat blank silk produced by a spinneret plate process, and the monofilament produced by the process is hard and has poor hand feeling; the produced three-folded silk (with the folded edge on the outer side) has sharp edges, can cause scratches when packaging thin-skinned agricultural products such as potatoes, sweet potatoes and the like, influences the sale of the agricultural products, and can also shorten the storage time of the agricultural products.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: the technical problem that the traditional mesh bag silk edges used for weaving plastic woven bags are sharp and can scratch agricultural products is solved.
The invention provides a plastic embryonic silk folding mechanism which comprises a first rubber roller and a first steel roller which are connected in a vertical rolling manner, wherein a first preheating roller is arranged on one side of the first steel roller, the upper end of the first preheating roller is flush with the upper end of the first steel roller, a folding device is arranged on one side of the first preheating roller, which is far away from the first steel roller, and a second rubber roller and a second steel roller which are connected in a vertical rolling manner are arranged on one side of the folding device, which is far away from the first preheating roller;
the folding device comprises a support, a thread guide plate arranged on the support and a folding roller arranged on the support, wherein a plurality of U-shaped grooves are formed in the lower end of the thread guide plate, a plurality of V-shaped grooves corresponding to the U-shaped grooves are formed in the folding roller, and the tops of the V-shaped grooves are higher than the tops of the U-shaped grooves;
the rotating speed of the second steel roller is 6-8 times faster than that of the first steel roller.
The working principle of the invention is as follows: the plastic flat blank wire enters from the joint of the first rubber roller and the first steel roller, is heated by the first preheating roller to be softer, then enters the U-shaped groove in the wire guide plate, so that the section of the plastic flat blank wire is changed into a U-shaped shape with a downward opening, then enters the V-shaped groove, and finally enters the joint of the second rubber roller and the second steel roller.
Further, a second preheating roller is arranged below the position between the first steel roller and the first preheating roller. The second preheating roller prolongs the running path of the plastic flat blank wire before being folded, so that the plastic flat blank wire has better preheating effect, is softer and is easier to form after entering the folding device.
Furthermore, a transition roller is arranged below the folding device and the second steel roller. The transition roller enables the embryonic filament to move obliquely downwards after coming out of the folding device, so that the contact area of the embryonic filament and the folding roller is increased, and the embryonic filament is easier to fold and form.
