Here, the support unit 202 is not limited to moving the preheating unit 210, the side heating unit 220, the bottom heating unit 230, and the curved unit up and down, and as necessary, the preheating unit 210, The side heating unit 220, the bottom heating unit 230, and the curved unit can each be moved up and down.

The support unit 202 may have various structures as long as the preheating unit 210, the side heating unit 220, the bottom heating unit 230, and the curved unit can be moved up and down. Here, the preheating unit 210, the side heating unit 220, the bottom heating unit 230, and the curve unit may be arranged to be sequentially spaced apart.

In addition, the support portion 202 is connected to a driving source, receives power from the driving source, and can be operated under the control of the processor 2.

Referring to FIG. 4, the preheating unit 210 may preheat the lower part of the paper tableware P in which the side and bottom are assembled before joining. Here, the lower part of the paper tableware (P) may mean an area where the bottom of the side of the paper tableware (P) and the edge of the bottom in contact with the bottom of the side overlap.

The preheating part 210 is located at the center of the cylindrical first edge part 211 and the first edge part 211, and is located at the center of the diagonal part 212 and the preheating part 210 whose height increases toward the center. It may include a flat top portion 213 that is located and formed flatly.

The first edge portion 211 may be disposed at an edge area of the preheating portion 210 to form the appearance of the preheating portion 210 . The first edge portion 211, together with the diagonal portion 212 and the flat portion 213, may form a preheating space (S210) for preheating the paper cutlery (P).

Accordingly, the first edge portion 211 can prevent heat from leaking into the preheating space S210 to the edge of the preheating portion 210.

The diagonal portion 212 extends from the bottom of the first edge portion 211, and its height may gradually increase toward the center of the preheating portion 210. That is, the diagonal portion 212 may have a slanted cross-sectional shape.

In addition, the diagonal portion 212 may include a first heating element H1 disposed below along the diagonal portion 212 to heat the surface of the diagonal portion 212 to a first temperature. Here, the first heating wire portion H1 may be made of a metal material with high thermal conductivity. For example, the first heating wire unit H1 may include a copper heating wire.

The first heating element H1 is connected to a heat source and its temperature can be adjusted under the control of the processor 2.

The flat portion 213 extends from the diagonal portion 212 and may be formed high and flat at the center of the preheating portion 210. The first heating element H1 may not be located in the flat top 213.

In addition, the first edge portion 211, the diagonal portion 212, and the flat top portion 213 are made of a metal material and may be formed as one piece.

Additionally, the first edge portion 211, the diagonal portion 212, and the flat top portion 213 may form a preheating space (S210) for preheating the paper cutlery (P).

Here, when the paper cutlery (P) is placed in the preheating space (S210), the processor 2 may raise the support unit 202 so that the paper cutlery (P) is spaced apart from the preheating unit 210.

That is, heat is dispersed from the diagonal portion 212 corresponding to the adhesive portion of the paper tableware (P), and the side (P1) and bottom (P2) of the paper tableware (P) located adjacent to the diagonal portion (212) are Since heat is concentrated in the overlapping area and is placed at a distance from the paper tableware (P), rapid heat increase in the paper tableware (P) can be prevented.

Accordingly, heat can be indirectly transferred to the side of the paper tableware (P) and the waterproof coating in the sea, distributing heat evenly over the entire area of the waterproof coating, thereby preheating the waterproof coating.

In other words, if heat is applied directly to the waterproof coating, the heat of the waterproof coating may be concentrated and only part of the waterproof coating may be melted or the paper tableware (P) located inside the waterproof coating may be damaged.

Therefore, heat can be evenly distributed to the waterproof coating through a structure in which the preheating unit 210 and the paper tableware (P) are spaced apart.

Referring to Figure 5, the side heating unit 220 inserts the cylindrical second edge portion 221 and the side (P1) and bottom (P2) of the paper tableware (P). It may include a joint 222 that joins the side P1 and the bottom P2 from the side.

The second edge portion 221 may be disposed at the edge of the side heating portion 220 to form the outer shape of the side heating portion 220. The second edge portion 221 may be made of a metal material.

The joint portion 222 may include a joint space (S220) into which the paper cutlery (P) is inserted and a second heating wire portion (H2) disposed adjacent to the joint space (S220). Here, the second heating wire portion H2 may be made of a metal material with high thermal conductivity. For example, the second heating wire unit H2 may include a copper heating wire.

The second heating element H2 is connected to a heat source so that its temperature can be controlled by the processor 2.

The joint 222 may be formed in a circular shape at the bottom of the side heating unit 220. Here, the cross section of the joint 222 may have a shape whose width gradually decreases toward the bottom.

In addition, the side (P1) and bottom (P2) of the paper tableware (P) are inserted into the joint portion 222, so that the side (P1) and bottom (P2) of the paper tableware (P) can be pressed and joined.

Here, the separation distance (L2) passing through the center of the side heating unit 220 is greater than the shortest distance (L1) between the side and bottom of one end of the paper tableware (P) and the side and bottom of the other end opposite to the one end. can be formed.

Accordingly, the side of the paper tableware (P) is structured so that its diameter gradually decreases toward the bottom, so when the area requiring joining of the paper tableware (P) is inserted into the joint 222, the paper tableware (P) The area where the side (P1) and the bottom (P2) overlap are physically spread, and in the process of spreading, a pressing force is applied to the area where the side (P1) and the bottom (P2) of the paper tableware (P) overlap, creating a strong physical bond between them. Upon contact, heat is applied and the waterproof coating partially melts, allowing them to be physically bonded to each other.

The processor 2 may raise the support portion 202 so that the side (P1) and bottom (P2) of the paper cutlery (P) are inserted into the joint portion (222). Here, the second temperature of the second heating wire unit (H2) can be controlled to be higher than the first temperature of the first heating wire unit (H1).

Here, the second temperature may be higher than the melting point of the waterproof coating. In addition, the side (P1) and bottom (P2) of the paper tableware (P) are in direct contact with the joint 222 and receive temperature, thereby greatly improving heat transfer efficiency.

The bottom heating unit 230 may include a cylindrical third edge portion 231 and a circular plate 232 connected to the third edge portion 231 and positioned at the lower portion.

The third edge portion 231 is disposed at the edge of the floor heating unit 230 and can form the external shape of the floor heating unit 230.

The circular plate 232 is formed integrally with the third edge portion 231 and may form the bottom of the bottom heating unit 230. In addition, the circular plate 232 may include a third heating element H3 disposed at the lower portion.

Here, the third heating wire portion H3 may be made of a metal material with high thermal conductivity. For example, the third heating wire unit H3 may include a copper heating wire. The third heating element H3 is connected to a heat source and its temperature can be adjusted under the control of the processor 2.

In addition, the third edge portion 231 and the circular plate 232 may form a bottom heating space (S230) where the paper cutlery (P) is placed.

The curved part 290 is located at the top of the holding part 291 and the holding part 291 that holds the paper tableware (P), and moves to the bottom to roll the upper end of the paper tableware (P). The gripper 291 may include a moisture port 291a that sprays water vapor along the outer peripheral surface of the gripper 291.

The grip portion 291 can fix the paper tableware (P) by contacting the inner surface of the paper tableware (P). In addition, the gripper 291 can rotate while holding the paper cutlery (P) as needed.

The pressing part 292 is structured to surround the holding part 291 on the upper side, and when necessary, the pressing part 292 moves to the lower part and interferes with the top of the paper tableware (P). Curling can be achieved by rolling the top of the paper tableware (P).

The moisture port 291a is disposed adjacent to the top of the paper tableware (P) along the outer peripheral surface of the grip part 291, and can spray water vapor on the top of the paper tableware (P) to provide moisture to the top.

The moisture outlet 291a is connected to an external water vapor source (not shown) and can selectively spray water vapor under the control of a processor.

Accordingly, during the process of drying the paper tableware (P), a certain amount of moisture is provided to the top of the paper tableware (P) under the control of the processor, so that the top of the paper tableware (P) is dried and curled. This can prevent tearing or damage.

At this time, the sprayed water vapor can be controlled by the processor to an amount that does not cause the paper cutlery (P) to become overhydrated.

The processor 2 may raise the support portion 202 so that the paper cutlery P contacts the circular plate 232.

That is, the processor 2 transfers heat directly to the bottom of the area where the side (P1) and the bottom (P2) of the paper tableware (P) overlap to push up or remove the part where the waterproof coating has flowed, thereby making the paper tableware (P) ) can be cleaned up.

In addition, the processor 2 may maintain the third heating element H3 at the third temperature. Here, the third temperature may be smaller than the second temperature and may be larger than the first temperature. Accordingly, if the third temperature is greater than the second temperature, damage may occur to the paper material, and if the third temperature is less than the first temperature, the waterproof coating may not melt.

Therefore, by contacting the paper tableware (P) at the third temperature, bonding of the waterproof coating to the bottom of the paper tableware (P) can be completed.

Accordingly, the paper tableware manufacturing apparatus 1 according to an embodiment of the present disclosure increases thermal efficiency by sequentially applying heat to the area where the side and bottom of the paper tableware P overlap and simultaneously applying physical bonding. This can greatly improve manufacturing stability.
