The apparatus for producing a knitted resin according to the present embodiment includes an extruder 20 that extrudes molten resin, a resin pool 30 that receives the molten resin extruded from the extruder 20 and causes the molten resin to flow down from a large number of holes in the bottom surface 31 into a thread shape. A molding induction roller 40 that receives thread-like molten resin (hereinafter referred to as thread-like molten resin) flowing down from the resin pool 30 and guides it to the cooling water, and a cooling water tank 50 that stores the cooling water are provided.

The thread-like molten resin is formed when it flows down from the hole in the bottom surface 31 of the resin pool 30.
The cooling water tank 50 includes a rotation roller 60 that hooks and pulls the knitted resin 10 formed by cooling the filament-shaped molten resin in the cooling water tank 50.
The extruder 20 melts and kneads the thermoplastic resin at a predetermined temperature to obtain a molten resin, and extrudes the molten resin to the resin pool 30 at a predetermined extrusion speed.

The forming guide roller 40 places cooling water on the forming guide roller 40 by positioning a part of the forming guide roller 40 in the cooling water. Since the cooling water always adheres to the cylindrical surface of the molding guide roller 40 due to the rotation, the molten resin does not adhere to the molding guide roller 40. In addition, it is preferable that the surface of the shaping | molding induction | guidance | derivation roller 40 is roughened so that a water film may be formed. The rough surface can be formed by, for example, sandblasting. Further, the surface of the forming guide roller 40 may be subjected to a hydrophilic treatment.

The molten resin extruded from the extruder 20 to the resin pool 30 flows down as a thread-like molten resin from the hole in the bottom surface 31 of the resin pool 30. At this time, a part of the filamentous molten resin reaches the forming induction roller 40 and then is guided to the cooling water tank 50, and the remaining filamentous molten resin is guided to the cooling water tank 50 without reaching the forming induction roller 40. Since the thread-like molten resin guided to the cooling water tank 50 after reaching the forming induction roller 40 has a higher density than the thread-like molten resin guided to the cooling water tank 50 without reaching the forming induction roller 40, the surface portion is internal. It is possible to form the knitted resin 10 that is dense with respect to the resin.
In other words, the high-density knitted resin layer 11 is formed by the thread-shaped molten resin guided to the cooling water tank 50 after reaching the forming induction roller 40, and is reduced by the thread-shaped molten resin guided to the cooling water tank 50 without reaching the forming induction roller 40. A density knitted resin layer 12 is formed.
As shown in the figure, when the thread-shaped molten resin reaches the pair of forming guide rollers 40, the knitted resin having a three-layer structure of the high density knitted resin layer 11, the low density knitted resin layer 12, and the high density knitted resin layer 13 is shown. 10 can be formed.
Further, when the thread-like molten resin reaches only one of the forming guide rollers 40, the knitted resin 10 having a two-layer structure of the high-density knitted resin layer 11 and the low-density knitted resin layer 12 can be formed.

In the molding step, a part of the thread-shaped molten resin is guided to the cooling water tank 50 after contacting the molding induction roller 40, and the remaining thread-shaped molten resin is guided to the cooling water tank 50 without contacting the molding induction roller 40.

  The apparatus for producing knitted resin according to the present embodiment is formed by changing the distance from the resin pool 30 to the water surface 51 by the resin pool moving means 71, so that the thickness or density of the thread-shaped molten resin changes. Ten hardnesses or mesh sizes can be varied.

  In the knitting resin manufacturing apparatus according to the present embodiment, the forming guide roller control means 72 changes the position of the forming guide roller 40 forward, backward, left, and right with respect to the resin pool 30, thereby reaching the forming guide roller 40. The number of molten resins can be changed, and by changing the distance between the forming guide roller 40 and the resin pool 30 or the distance between the forming guide roller 40 and the water surface 51, the hardness of the filamentous molten resin or the mesh size can be changed. Can be changed. Further, the density of the filamentous molten resin can be changed by changing the radial dimension of the forming guide roller 40.

  Further, in the knitting resin manufacturing apparatus according to the present embodiment, the water surface changing means 75 can change the distance from the forming guide roller 40 to the water surface 51, so that the thickness or density of the thread-like molten resin changes. The hardness of the resin 10 or the size of the mesh can be changed.

  In addition, it is preferable to provide the constant temperature member 90 formed in the cylinder or the polygonal cylinder between the resin pool 30 and the shaping | molding induction | guidance | derivation roller 40. FIG. The constant temperature member 90 surrounds the periphery of the thread-shaped molten resin from the resin pool 30 to the forming guide roller 40, thereby preventing a temperature decrease of the thread-shaped molten resin. The filamentous molten resin is cooled by being affected by wind, for example, from the resin pool 30 to the forming guide roller 40. The constant temperature member 90 prevents cooling of the filamentous molten resin by at least blocking the flow of wind. For example, it is effective when using a thermoplastic resin having a high freezing point such as polyethylene terephthalate (PET) and capable of solidifying before reaching the water surface.

In the knitting resin manufacturing apparatus according to the present embodiment, the speed changing means 76 changes the rotational speed of the rotary roller 60, so that the density and elasticity of the thread-shaped molten resin and the knitting resin 10 and the cooling water tank 50 are changed. The cooling time of the knitting resin 10 can be changed.
By repeating the operation of the rotation speed of the rotating roller 60 at a speed V1 for a predetermined time T1, and the operation at a speed V2 (however, V1> V2, V2 may be zero) for a predetermined time T2 (where T1> T2), The high-density knitted resin layer 11 in the width direction can be obtained at a predetermined interval. Further, the high-density knitted resin layer 11 in the longitudinal direction can be obtained by a pair of molding guide rollers 40. Therefore, the knitting resin 10 shown in FIG. 9 can be obtained by cutting with the high-density knitting resin layer 11 in the width direction.
