Description

Paper container foaming device

The present invention relates to a paper container foaming device.

Background technique

Generally known heat-insulating disposable containers are often used for hot drinks or hot soups, and the heat-insulating layer is usually a foamed layer, which is coated with a foamed material on the outer wall of the formed paper container, and then applied at a high temperature. Its foaming expands.

In the currently known technology, a paper container carrying a plurality of coated foamed materials in a conveyor belt is foamed by a heating device, and after foaming and cooling are completed, the stack is collectively collected. However, in such a structure, the paper containers are placed directly on the conveyor belt and then moved forward with the conveyor belt, that is, the paper containers are randomly distributed on the conveyor belt, if paper containers of different colors or sizes are simultaneously placed On the conveyor belt, the final centralized recycling step will result in uneven specification of the recycled stacked paper containers, which is more unfavorable for classification; however, if only one paper container of the same specification can be placed in a foaming process, it will be very disadvantageous for multiple specifications. A small amount of manufacturing not only lengthens the processing time, but also wastes energy.

Referring to FIG. 1 to FIG. 5, the present invention provides a paper container foaming device for heating and foaming a foaming material of a plurality of unfoamed paper containers 80, wherein the foaming material is coated on each of the unfired materials. The outer wall surface of the foam container 80, in the main embodiment of the present invention, the paper container foaming device comprises a feeding portion 10, a heating portion 20, a cooling portion 30, a receiving portion 40 and a complex a plurality of movable loading blocks 50, wherein the feeding portion 10, the heating portion 20, the cooling portion 30 and the receiving portion 40 are sequentially arranged in a machine, and the loading blocks 50 are located in the machine. The feeding portion 10, the heating portion 20, the cooling portion 30, and the receiving portion 40 are sequentially passed.

Each of the carriers 50 is arranged to carry the unfoamed paper containers 80 and the respective carriers 50 are sequentially arranged in the direction in which they move. Each of the carriers 50 includes a moving mechanism and a plurality of sockets 51. Arranging in a direction perpendicular to the moving direction of the carrier 50, each of the sockets 51 includes a rotating mechanism, and the rotating mechanism rotates the bearing 51 about a predetermined rotating shaft when the respective loading blocks 50 are moved by the moving mechanism. The predetermined rotation axis is perpendicular to the moving direction of the carrier 50. In more detail, the moving mechanism includes a strip conveying structure 70, and the carrier 50 is fixed to the strip conveying structure 70 and can be carried by the strip conveying structure 70 to move in a predetermined direction, wherein the strip conveying structure 70 extends to The material portion 10, the heating portion 20, the cooling portion 30, and the receiving portion 40 are in a circulating shape, and the carrier 50 is transported from the feeding portion 10 to the heating portion 20, the cooling portion 30, and the receiving portion 40, and is fed back. Material section 10. In another aspect, the paper container foaming device provided by the present invention has a plurality of rails 60. The rotating mechanism of each of the sockets 51 includes a gear 52 disposed coaxially with the socket 51. The gear 52 and one of the rails 60 abut each other. When the moving mechanism drives the carrier 50 to move, the socket 51 rotates due to the friction between the gear 52 and the rail 60. More specifically, each rail 60 is located between any two adjacent sockets 51 and opposite to each other. The sides respectively have an abutting surface 61, and the gears 52 on both sides of each rail 60 respectively abut against the two abutting surfaces 61. In addition, the top of each of the sockets 51 has a support portion 511 having a large outer diameter, and the socket 51 can extend into the interior of the unfoamed paper container 80, and the support portion 511 supports the bottom of the unfoamed paper container 80. The unfoamed paper container 80 is erected, and the opening of the unfoamed paper container 80 is open to communicate with the outside, so that the hot air enters the inside of the unfoamed paper container 80 to help accelerate the foaming speed, and also enables the hot air. At the same time, the inner foaming material is heated and foamed from the inside to avoid excessive foaming of the outer foaming material but less foaming of the inner foaming material.

The feeding portion 10 includes a plurality of feeding tubes 11 which are arranged longitudinally and in parallel, and a feeding port 111 is formed at the bottom end of each feeding tube 11, and the feeding tubes 11 are accommodated for not being placed. The foam container 80 transports the unfoamed paper container 80 to the feed port 111, wherein the opening of each unfoamed paper container 80 faces downward and the bottom faces upward, and the arrangement of the feed port 111 and the arrangement of the socket 51 Correspondingly, that is, each feeding port 111 corresponds to one of the sockets 51. When the carrier 50 is moved to the feeding portion 10, the sockets 51 respectively receive the unfoamed paper containers 80 output from the feeding port 111. . The heating unit 20 has at least one heating device 21 and at least one airflow guiding device. The heating device 21 is preferably a heating plate disposed on the top of the heating portion 20. The airflow guiding device includes a plurality of air supply ports 22 and at least one return. The gas port 23, each gas supply port 22 is located at the top of the heating portion 20, the gas return port 23 is located at the bottom of the heating portion 20, and the gas supply port 22 can output an air flow to the heating portion 20 (for example, a nozzle discharge gas flow), and the gas return port 23 can The airflow is sucked from the heating portion 20 to guide the heat generated by the heating device 21 downward. Preferably, the air supply port 22 and the air return port 23 communicate with each other to form an air circulation system, and further, the heating device 21 is below. There is also a baffle 24 for blocking the heat generated by the heating device 21 from directly radiating downward. In particular, when the carrier 50 carrying the unfoamed paper container 80 enters the heating portion 20, the position of each air supply port 22 corresponds exactly between two adjacent sockets 51, so that the air supply port 22 is provided. The ejected air stream can carry heat to the outer wall of the unfoamed paper container 80 carried on the two adjacent sockets 51 to surely heat-expand the foamed material.

The cooling unit 30 is configured to cool the heat-foamed paper container 80' for subsequent collection, packaging, etc., that is, when the carrier 50 carrying the heated foamed paper container 80' is cooled. In the portion 30, the cooling unit 30 cools the paper container 80'.

The receiving portion 40 includes a plurality of receiving tubes 41. The receiving tubes 41 are arranged longitudinally and in parallel, and a receiving port 411 is formed at the bottom end of each receiving tube 41. The receiving ports 411 are respectively facing the socket. The paper container 80' which has been foamed on 51 is recovered and transported upward through the receiving tubes 41 for subsequent packaging operations. The arrangement of the receiving port 411 and the receiving tube 41 corresponds to the arrangement of the socket 51. When the carrier 50 carries the foamed paper container 80' into the receiving portion 40, the receiving port 411 and the bearing The positions of the seats 51 correspond to each other, so that each of the receiving ports 411 can separately collect the paper containers 80' on one of the sockets 51. In other words, the feed port 1 11 corresponding to the paper container 80' is aligned with the receiving port 41 1 and corresponds to each other, so that the same group of paper containers 80' can be output by the same feed port 111 and be in the same position. The socket 51 is carried and foamed, and is recovered by the same receiving port 411. The same group is maintained before and after the process without confusion.

In actual operation, as shown in FIG. 6 and FIG. 2, the user can place the same group of unfoamed paper containers 80, 80a in each feeding tube 11 (for example, the same size, the same color, the same style or the same customer) The goods of the order are corresponding to each other through the feed port, the socket and the receiving port, and the unfoamed paper containers 80, 80a of the same group can be carried and foamed by the socket 51 at the same position, and then received by the same The material port 411 is recycled, stacked, and even packaged, so that, as shown 6 As shown in Fig. 2, different groups of paper containers can be transported, foamed, cooled and recycled simultaneously by being placed in different feeding tubes 11, and are not mixed with other groups of paper containers, only Paper containers with the same group will be recycled and stacked, which is quite conducive to subsequent processing, packaging and sorting operations, and can also be applied to small quantities, that is, when each feeding tube is placed in a paper container The average is divided into different groups, that is, a small amount of multi-style production can be performed in a short time.

The airflow guiding device in the invention can effectively transfer the heat generated by the heating device downwards quickly and uniformly, avoiding the problem of local excessively high temperature and insufficient local temperature, thereby avoiding excessive foaming and foaming in a region with more heat. Even the high temperature penetrating paper container destroys the inner laminating layer, and the less heated area is incompletely foamed; further, since the air supply port of the air guiding device is just aligned with the two adjacent sockets In other words, the airflow from the air supply port carries heat and reaches the outer wall of the two adjacent sockets, so that the heating efficiency is improved; even, because the airflow flows downward, the paper container can be more firmly supported. On the seat, it is not easy to overturn and affect the yield.

On the other hand, since the socket rotates while moving, the outer wall of the carried paper container can be uniformly heated, and even if the heating portion is not heated uniformly, the socket can still be lowered by rotating the outer wall of the paper container. The difference in the degree of bubble.

In addition, the socket can support the paper container so that the opening of the paper container communicates with the outside to be open, that is, the hot air can enter the inside of the paper container, and the inside and the outside are simultaneously heated to accelerate the foaming and make the heating more uniform.

In summary, the present invention has a plurality of spaced-apart carrier holders that continuously move forward through the refining conveyor structure, thereby achieving rapid, high-volume production, and the products of different groups are not mixed with each other. Rotating and supporting seats and high-speed airflow with hot air increase heating rate and uniformity, greatly improving yield, production and production efficiency, and are highly effective.

The above is a preferred embodiment of the present invention and the technical principles of the present invention, and those skilled in the art, based on the technical solutions of the present invention, without departing from the spirit and scope of the present invention. Obvious changes such as equivalent transformations, simple substitutions, and the like are all within the scope of the present invention.
