When the raw material R is a mixture of two or more types of components having different specific gravities, such as a mixture of a fiber and a binder resin, the components are separated and unevenness occurs. There was a problem of becoming.

[0004]

According to the present invention, as a means for solving the above-mentioned conventional problems, a lower conveyor belt () is suspended around a plurality of rollers (15) supported in a chamber (2). 13) and an upper conveyor belt (14) suspended by a plurality of rollers (16) supported by a sliding frame (3) arranged to be able to slide back and forth with respect to the chamber (2).
And a raw material supply tank installed on the upper surface of the chamber (2)
(5) An oblique forming part (17) is formed between the lower conveyor belt (13) and the upper conveyor belt (14) from the upper side to the lower side, and the raw material supply tank (5 ), A raw material supply port (6) is provided on the upper surface, and a raw material discharge port (7) is provided on the side surface of the raw material supply tank (5).
(14) The chamber (2) is connected to the chamber (2) through the opening (18) immediately above, and a plurality of raw material leveling rolls (28) are arranged in the raw material supply tank (5) in the horizontal direction. A forming device (1) is provided.

[0005]

The raw material R is sent from the raw material supply port (6) to the raw material supply tank (5) and falls onto the upper conveyor belt (14) through the opening (18). ) And supplied to the upper end of a forming section (17) formed between the lower conveyor belt (13) and the upper conveyor belt (14) in the chamber (2). The raw material R is pressed between the lower conveyor belt (13) and the upper conveyor belt (14) in the forming section (17) to form the mat M. In the raw material supply tank (5), surplus raw material R is discharged from a raw material discharge port (7),
Since (17) is inclined downward from above, the raw material weight is hardly affected in the forming section (17). The thickness of the mat M is adjusted by sliding the sliding frame (3) back and forth to adjust the distance between the lower conveyor belt (13) and the upper conveyor belt (14) in the forming section (17), that is, the width of the forming section (17). It is possible to adjust by doing. If the width of the forming part (17) is gradually reduced from the upper part to the lower part, the raw material R is gradually pressed in the forming part (17), so that the mat M can be formed smoothly.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to one embodiment shown in FIGS. 1 to 4. In a chamber (2) of a forming apparatus (1), a lower conveyor belt (13) and an upper conveyor belt (14) are provided.
And the lower conveyor belt (13) is a chamber.
The upper conveyor belt (14) is suspended by a plurality of rollers (15) supported in (2), and the upper conveyor belt (14) is supported by a sliding frame (3) arranged to be slidable back and forth in the chamber (2). It is suspended on a plurality of supported rollers (16), and between the lower conveyor belt (13) and the upper conveyor belt (14), an oblique forming part (17) that goes downward from above. Are formed, and the width of the forming portion (17) gradually decreases from the upper portion to the lower portion.

A chain (24) is suspended from a motor (4) around a roller (15) at one end of the lower conveyor belt (13) and a coaxial outer sprocket (20) outside the chamber (2). Further, a chain is provided between the inner sprocket (21) coaxial with the outer sprocket (20) and the roller (16) at one end of the upper conveyor belt (14) and the coaxial sprocket (22).
(25) is suspended, a tension sprocket (23) is further interposed in the chain (25), and the tension sprocket (2
3) is shown in FIG. 4 through an arm (27) by an air cylinder (26).
It is urged in the direction of the arrow to exert tension on the chain (25).

A raw material supply tank is provided on the upper surface of the chamber (2).
A material supply port (6) is provided on the upper surface of the material supply tank (5), and a material discharge port (7) is provided on the side surface. The raw material supply tank (5) is connected to the chamber through an opening (18).
(2) is communicated directly above the upper conveyor belt (14),
A plurality of raw material leveling rolls (28) are arranged inside the raw material supply tank (5), and as shown in FIG. A sprocket (29) is coaxially mounted on the outer side of the shaft, and a chain (30) is suspended from a motor (8) on each sprocket (29). A mat receiving conveyor (19) is connected to a lower end of the forming portion (17) between the lower conveyor belt (13) and the upper conveyor belt (14).

The sliding frame (3) comprises both side plates (31) and a connecting beam (32) for connecting the both side plates (31) at the upper end, and a screw is provided at the center of the foremost connecting beam (32). A block (33) is attached, and the screw block (33) is supported by a bearing (34) suspended from the upper surface of the chamber (2).
5) is screwed, and a handle (3) is attached to the tip of the screw rod (35).
6) is installed. The lower edge of the both side plates (31) is slidably fitted to rails (37) attached to both sides of the chamber (2) as shown in FIG.
(3) is guided by the rail (37) and slides back and forth.

In the forming apparatus (1), a raw material adjusting tank (38) with a stirrer is connected to the raw material supply port (6) through a raw material supply path (39), and the raw material supply path (39) is connected to the raw material supply path (39). Blower
(40) intervenes, and the raw material discharge port of the forming device (1)
(7) is connected to a raw material adjusting tank (38) via a raw material return path (41). The handle (36) rotates the screw (35) forward and backward, and the sliding frame (3) moves forward or backward to form the forming section.
The width between the lower conveyor belt (13) and the upper conveyor belt (14) in (17) is adjusted. Then, the motor (4) and the motor (8) are driven to circulate the upper and lower conveyor belts (13, 14) at a constant speed, and the material leveling roll (28) is rotated in the direction of the arrow in FIG. Then, the mat receiving conveyor (19) is circulated in the direction of the arrow in FIG.

Next, the blower (40) of the raw material supply path (39) is operated to remove scraps of waste paper, scraps such as felt and fiber knitted fabric, synthetic fibers, wood fibers, bamboo fibers, hemp from the raw material adjusting tank (38). Raw material R, which is a mixture of fibers such as fibers and coconut fibers and binder resins such as phenolic resin, melamine resin, urea resin, polyethylene, polypropylene, and acrylic resin, is supplied through a raw material supply port (6) to a raw material supply tank (5). The raw material R is dropped from the raw material supply tank (5) through the opening (18) onto the upper conveyor belt (14) in the chamber (2). At this time, the raw material R on the upper conveyor belt (14) is prevented from forming a block by the raw material leveling roll (28), and between the lower conveyor belt (13) and the upper conveyor belt (14). To the upper end of the forming section (17).

The raw material R dropped on the forming section (17) is clamped between the lower conveyor belt (13) and the upper conveyor belt (14), and has a thickness as it moves to the lower end of the forming section (17). It is gradually compressed and formed into a mat M, received by a mat receiving conveyor (19), and introduced into, for example, a heating furnace or a hot press (not shown).

In the raw material supply tank (5), surplus raw material R is discharged from a raw material discharge port (7), returned to a raw material adjusting tank (38) via a raw material return path (41), and further provided with a lower conveyor. Since the forming portion (17) between the belt (13) and the upper conveyor belt (14) is inclined, the weight of the raw material R is hardly exerted in the forming portion (17), and the separation of the fiber and the binder resin is performed. The mat M having a uniform density and a uniform composition is formed.

[0014]

According to the present invention, when the mat is formed by pressing the raw material in the forming section between the lower conveyor belt and the upper conveyor belt, the weight of the raw material hardly affects the forming section. A mat having a uniform density, composition and composition is smoothly formed.
