A regulator valve 15 is released under this state, compressed air is supplied to a coloring agent tank 10 through air piping 13, adjusted by a flow adjusting valve 11 and a coloring agent 7 is poured into the scores 4 from the tip of an injection needle 12 through a supply pipe 16.

Description

[Detailed description of the invention]

[Technical Field] The present invention relates to an apparatus for manufacturing a linear colored molding material by continuously applying linear coloring to a molding material extruded from an extruder. [Background technology] In the past, an operator manually made lines (4) with a cutter knife in the molding material (3) extruded from an extruder, and then made the lines (4) with a so-called corner cutter made of bamboo. Colorant (7) was injected to produce linear colored molding material +91", but
Not only is workability poor, but the colored pattern may vary due to individual differences among workers, and the injected colorant (7) can be pushed away with a cutting tool, resulting in streaks (4) of the molding material (3) as shown in Figure 1. The coloring agent (7) was sticking out. [Objective of the Invention] The object of the present invention is to manufacture a linear colored molding material that enables continuous production of a linear colored molding material, greatly improves productivity, and allows for arbitrary linear coloring. The goal is to provide equipment. [Disclosure of the Invention] (Configuration) The manufacturing apparatus of the present invention includes an outlet nozzle (2) of an extruder (1).
A cutter (5) is placed adjacent to the extruded molding material (3) to insert the creases (4) into the extruded molding material (3), and a cutter (5) which inserts the creases (4) into the extruded molding material (3), and a receiver 0- which supports the molding material (3) in a horizontal state with 41 creases inserted therein.
The colorant (71) is continuously injected into the grooves (4) of the molding material (3) supported horizontally by the cutter (6). By inserting the groove (4) into the groove and continuously injecting the coloring agent (7) into the groove (4) using the syringe (8), the above objective was achieved. (Example) vJ2 Figures 3 and 3 show an embodiment of the present invention.
), there are streaks (4) in the extruded molding material (3).
) are held at predetermined intervals by a cutter holder (not shown). The plurality of cutters (6) are set at an angle of 01 to 10 to prevent the molding material (3) from escaping when making the creases (4). 900, it is held in the cutter holster so that it can move up and down, adjust the spacing, and tilt freely.The depth d of the grooves (4) is T// with respect to the thickness T of the molding material (3). The molding material (3) with grooves (4) placed in front of the outlet nozzle (2) of the extruder (1) is placed in the range of 2 to T/3. A receiver O-ra (8) is arranged.In front of the cutter (6), a viscous coloring agent (7) such as a mixture of pigment, dye or fcIfi carbon black and styrene chlorine is molded. Feed compressed air into the colorant tank (lO) through the supply pipe (l: 1) to the line +41 of material (3), adjust the flow rate by adjusting the pulp (1), and insert the injection needle (12 + colorant + 71t). - Molding material (3
) so that it can be injected into the muscle (4). A band heater is placed around the outer periphery of the g outlet nozzle (2). The operation of the above embodiment configured as follows will be explained. Extruder +11 for resin molding materials such as polyester
The sheet-shaped molding material (3) that has been put into the machine, mixed, melted, and extruded from the exit nozzle (2) now has a degree of θ of 9.
Cutter (6) set at 0° has multiple lines (
4) is included. The molding material (3) into which the grooves (4) have been inserted is maintained in a horizontal state by the receiving rows 5 (6). In this state, the ink letter pulp (I5) is opened and compressed air is supplied to the coloring agent tank (l) through the air pipe 031t.
The coloring agent (7) is sent to the tip of the supply pipe O @ the injection needle 02), and the coloring agent (7) is sent to the flow rate adjusting pulp (1) and the coloring agent (7) is fed to the tip of the supply pipe O ). In this way, a sheet-shaped linear colored molding material (9) is produced. In this linear colored molding material (9), the amount of colorant (7) is adjusted by the flow rate regulating pulp (Ill), so it does not protrude from the streaks (4) as shown in Figure 4. This sheet-shaped linear colored molding material 191 Fi is cut into predetermined dimensions and then used as a molding material for a molded product having a marble pattern. Fig. 5 shows another embodiment of the present invention. This is an example, and in this embodiment, a rotational speed detection unit 0η? such as a photoelectric sensor is housed in the receiver 0-ra (6), and the receiver 0-ra (6) corresponds to the extrusion speed of the molding material (3).
6) is detected and fed back to the injector (8) to control the amount of colorant (7) injected into the veins (4) and change the injection pattern. It is possible. FIG. 6 shows still another embodiment of the present invention, in which a plurality of cutters (6) are arranged in front of the outlet nozzle + 21 of the extruder (1; Container (8) T - Two units are placed at the upper and lower sides, and several II lines 1411 are placed on the upper and lower surfaces of the extruded molding material (9), and the coloring agent (7) is injected into these lines (4). I'm trying to make it possible.'1

【Effect of the invention】

In the present invention, since the cutter is placed adjacent to the exit nozzle of the extruder, the extruded molding material is not completely cooled and is easily scored by the cutter.5. ! ! A cutter is used to continuously score the molding material, and the molding material with the streaks is supported in a horizontal position by a 9-piece machine, and the coloring agent can be continuously injected into the streaks using a syringe. can be carried out stably, and furthermore, by adjusting the amount of coloring agent injected using a syringe, it is possible to color the molding material in an arbitrary linear manner.
