The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Referring to fig. 1 to 2, a schematic structural diagram of a nozzle wire drawing and cutting device in an embodiment of the present invention is shown, and fig. 1 and fig. 2 are different in terms of placing angle. The nozzle wire drawing and cutting device in the embodiment comprises a recovery part 1, a cutting part 2 and a limiting part 3. The product placing device is further provided with a placing table 4 for placing a demoulded product 5, and the limiting portion 3 is used for limiting the product 5 placed on the placing table 4. The recovery unit 1 and the cutting unit 2 are located on the side of the placement table 4. The recovery part 1 is positioned below the water gap 51, and the raw material in a molten state in the water gap 51 is drawn into a wire shape by the suction force of the recovery part 1, and is continuously sucked into the recovery part 1. The cutting section 2 is located between the nozzle 51 and the collection section 1 and cuts the drawn wire.

The limiting part 3 includes a first limiting rod 31, a second limiting rod 32, a connecting plate 33 and a limiting cylinder 34. A first stopper rod 31 is fixed to a first side of the placement table 4, and a stopper groove 41 is provided on a second side. Wherein the first side is a side adjacent to the cut portion 2, and the second side is an opposite side of the first side. The second limit rod 32 is fixedly connected with a connecting plate 33, and the connecting plate 33 is connected with a limit cylinder 34. The limiting cylinder 34 can drive the connecting plate 33 and the second limiting rod 32 to slide in the limiting groove 41, so that two sides of the product are respectively supported by the first limiting rod 31 and the second limiting rod 32. In the present embodiment, the number of the first limiting rods 31 and the number of the second limiting rods 32 are set to be 2, but other numbers are also possible.

The recovery part 1 comprises a recovery port 11 and a suction device, the recovery port 11 is communicated with the suction device, and after the suction device is opened, raw materials which are not completely solidified in a water gap 51 positioned above the recovery port 11 are sucked into the recovery port 11.

While the incompletely solidified raw material moves toward the recovery port 11 by the suction force of the suction device, the raw material is rapidly cooled and solidified when contacting with air in a normal temperature state, and the temperature in the nozzle 51 gradually decreases as the molten raw material in the nozzle 51 is continuously sucked away, and the raw material remaining in the nozzle 51 also starts to solidify. Since the wire is already cooled and solidified at this time, the wire cannot be broken only by the suction force of the suction device, and therefore, an additional cutting section 2 is required to cut the wire.

The cutting unit 2 includes a cutting blade 21 and a cutting power source 22, and the cutting blade 21 is connected to the cutting power source 22 and is capable of moving toward the wire under the drive of the cutting power source 22 to cut the wire. The cutting power source can be a cylinder or a motor and the like. The suction device can quickly suck the cut wire drawing and prevent the wire drawing from winding on a cutter or other components. A recessed portion 211 is provided at an end of the cutting blade 21, and when the cutting portion 2 moves toward the wire, the wire enters the recessed portion 211 and is cut. Because this depressed part 211 has certain space can block the wire drawing, can play certain limiting displacement to the wire drawing, prevent that the wire drawing from sliding along the cutting edge and can't cut off.

In the above embodiment, the placing table 4 is divided into the left placing table and the right placing table, the recovery portion 1 and the cutting portion 2 are located between the left placing table and the right placing table, the left side and the right side of the product 5 are respectively placed on the left placing table and the right placing table, and the water gap 51 is suspended downward and extends from the space between the left placing table and the right placing table. However, the present invention is not limited to this, and only one placing table may be used. In fact, the placing table can be matched with the size and shape of the product as long as the water gap can be fixed in position without shaking, and the recovery part 1 and the cutting part 2 are located on one side of the placing table 4.

In the present embodiment, the product 5 is limited by the first limiting rod 31 and the second limiting rod 32, so that the position of the nozzle 51 integrally connected with the product is fixed and can be located in the range of the recess 211 of the cutting tool 21. However, no stopper is provided in the cutting direction of the cutting section 2 because the suction force of the suction device is large, and the molten raw material in the nozzle 51 can be sucked out even if the recovery port 11 is not located directly below the nozzle 51 in this direction. Therefore, the water gap 51 only needs to be positioned within the range of the recessed portion 211 of the cutter 21 in the direction perpendicular to the cutting direction in the horizontal plane.

Of course, a set of limiting rods can be arranged to limit the product along the cutting direction. In another embodiment of the present invention, the limiting portion includes a first limiting rod, a second limiting rod, a third limiting rod, a fourth limiting rod, a first limiting cylinder and a second limiting cylinder. The first side of the placing table is fixed with a first limiting rod, the second side of the placing table is provided with a first limiting groove, the second limiting rod is connected with the first limiting cylinder, and the second limiting rod can move along the first limiting groove under the driving of the first limiting cylinder. A third limiting rod is fixed on the third side of the placing table, a second limiting groove is formed in the fourth side of the placing table, a fourth limiting rod is connected with a second limiting cylinder, and the fourth limiting rod can move along the second limiting groove under the driving of the second limiting cylinder.

In addition, a groove matched with the shape of the product can be arranged on the placing table 4, and the product is placed in the groove for limiting.

The collecting section 1 and the cutting section 2 may be provided on the top of the placing table 4, and the water gap 51 may be directed upward when the product 5 is placed on the placing table 4. However, it is preferable that the recovery part 1 and the cutting part 2 are positioned at the bottom of the placement stage 4 with the nozzle 51 facing downward. Since the nozzle 51 is directed downward, the raw material in a molten state in the auxiliary nozzle under the action of gravity can be removed more quickly.

While the preferred embodiments of the present invention have been described in detail, the present invention is not limited to the embodiments, and those skilled in the art can make various equivalent modifications and substitutions without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
