Description

Technical Field

[0001] This utility model belongs to the technical field of plastic molding equipment, specifically, it relates to an edge-heating device. Background Technology

[0002] Spring-structured resin molded products are three-dimensional structures with a certain bulk density and porosity. These structures are formed by thermoplastic resins and / or thermoplastic elastomers, which are connected through contact, interweaving, and aggregation to create solid and / or hollow ring-shaped or coiled structures. The three-dimensional structure possesses good elasticity and breathability, making it a novel type of elastic pad material. Chinese utility model patent CN216609995U, published on May 27, 2022, discloses a three-dimensional structure molding device for producing block-shaped three-dimensional structures, which are rectangular in shape after production. This three-dimensional structure has the following inherent defects, requiring further processing.

[0003] (1) When the sides of a three-dimensional structure are formed, they are in a free and stretched state, which makes the sides of the three-dimensional structure fluffy and messy after forming, and cannot be used directly.

[0004] (2) After the three-dimensional structure is cut according to the usage requirements, there are burrs at the cut.

[0005] Therefore, when using it, the sides of the three-dimensional structure need to be processed to make them flat. Utility Model Content

[0006] 1. The problem to be solved

[0007] To address the problems existing in the prior art, this utility model provides a hot-edge heating device that uses high-temperature melting to flatten the sides of a three-dimensional structure.

[0008] 2. Technical Solution

[0009] To solve the above problems, the present invention adopts the following technical solution:

[0010] An edge-heating device includes a pad for placing the material to be heated; and a heating plate located at the edge of the pad and perpendicular to it. The heating plate contains several heating rods that continuously supply heat required for heating. In use, a three-dimensional structure is placed on the pad. Once the heating plate reaches a certain temperature under the heat of the heating rods, the side of the three-dimensional structure to be flattened is manually pushed towards the heating plate, and a certain pushing force is applied. When the side of the three-dimensional structure is attached to the heating plate, the adhesive threads on its side are melted by the high temperature of the heating plate, and under the continuous pushing force, the side becomes flat.

[0011] Preferably, a non-woven fabric is adhered to the side of the heating plate facing the pad. The non-woven fabric is heat-resistant and non-adhesive. By using non-woven fabric to adhere to the heating plate, the adhesive filaments of the three-dimensional structure will not stick to the heating plate after melting, facilitating the separation of the three-dimensional structure from the heating plate after its sides have been flattened.

[0012] Preferably, the heating plate is provided with a plurality of blind slots evenly distributed therein, and the heating rod is placed in close contact with each blind slot.

[0013] Preferably, the heating plate is surrounded by a baffle plate. The baffle plate can reduce the heat radiation of the heating plate to a certain extent, preventing the heating plate from affecting the surrounding environment or objects. At the same time, it also reduces the heat dissipation rate of the heating plate, reducing heat loss.

[0014] Preferably, the shielding plate includes a long side plate and a short side plate, the ends of which are connected to form an L-shaped plate.

[0015] Preferably, a junction box is fixed on the side of the shield, and the junction box contains a power supply for connecting the heating rod.

[0016] Preferably, the heating rod includes a cylindrical metal shell with a resistance wire inside, the resistance wire being connected to the power source via wiring.

[0017] Preferably, the pad has a notch. The notch allows a worker to stand, facilitating edge heating operations on small-volume three-dimensional structures.

[0018] Preferably, the pad is provided with a support column at the corner to support the weight of the pad.

[0019] Preferably, the heating plate used for heating has a flat or curved surface shape. Attached Figure Description

[0025] The following detailed description of exemplary embodiments of the present invention refers to the accompanying drawings, which form part of the description, illustrating exemplary embodiments in which the present invention may be implemented. Although these exemplary embodiments have been described in sufficient detail to enable those skilled in the art to implement the present invention, it should be understood that other embodiments may be implemented and various changes may be made to the present invention without departing from the spirit and scope thereof. The more detailed description of embodiments of the present invention below is not intended to limit the scope of the claimed invention, but is merely illustrative and does not limit the description of the features and characteristics of the invention, in order to suggest the best mode for carrying out the invention and sufficient to enable those skilled in the art to implement it. Therefore, the scope of the present invention is defined only by the appended claims.

[0026] To address the above issues, the following explanation is provided in conjunction with the accompanying drawings:

[0027] like Figure 1 As shown, this utility model provides a hot-pressing device for processing the sides of a three-dimensional structure to make it flat. The hot-pressing device includes a pad 1. The pad 1 is a thin rectangular plate with a smooth surface to reduce the friction of the three-dimensional structure on it. The pad 1 is preferably made of stainless steel. The pad 1 has a U-shaped notch 11 to facilitate the operator's standing position when handling some smaller three-dimensional structures. Four support columns 7 are fixed at the four corners below the pad 1 to support the weight of the entire pad 1.

[0028] like Figure 1-3 As shown, a heating plate 2 is vertically mounted on the side of the pad 1. The function of the heating plate 2 is to heat the sides of the three-dimensional structure, melting them. The heating plate 2 is also a cuboid plate, with its heating surface perpendicular to the pad 1. There are three heating plates 2, distributed on the three sides of the pad 1, forming a U-shape. The purpose of using three heating plates 2 is to allow the three-dimensional structure to be heated and flattened on two sides simultaneously. Compared to using one heating plate 2, which requires rotating the three-dimensional structure four times, using three heating plates 2 only requires one rotation. This greatly saves processing time. Along its length, the heating plate 2 has several blind grooves 21 inside. The blind grooves 21 extend from the side of the heating plate 2 along its width into the interior of the heating plate 2. A heating rod 3 is placed in each blind groove 21, fitting against the side wall of the blind groove 21, to provide the heat required for heating the entire heating plate 2. The blind grooves 21 are evenly distributed along the length of the heating plate 2 to ensure uniform heating of the heating plate 2. The heating plate 2 can be flat or curved, and its shape is adapted to the processing surface of the product to be processed.

[0029] The heating rod 3 includes a heat-conducting outer shell 31, such as an aluminum metal shell 31. Inside the outer shell 31 is a resistance wire 32, and the two ends of the resistance wire 32 are connected to a power source via wires 33.

[0030] How to use the edge-heating device:

[0031] (1) Power the heating rod 3 so that it heats the heating plate 2 to a certain temperature;

[0032] (2) The operator places the three-dimensional structure to be heated on the pad 1 and pushes the three-dimensional structure toward the heating plate 2 so that the two adjacent sides of the three-dimensional structure are in contact with the corresponding heating plate 2.

[0033] (3) Simultaneously apply a thrust to the three-dimensional structure and hold for 30 seconds;

[0034] (4) Remove the three-dimensional structure from the heating plate 2;

[0035] (5) Rotate the three-dimensional structure by 90° so that the side of the structure that is not heated is in contact with the heating plate 2, apply a pushing force, and hold for 30 seconds to complete the heating of the entire three-dimensional structure.

[0036] During use, because the heating plate 2 is metal, the plastic on the side of the three-dimensional structure tends to stick to the heating plate 2 after melting, making it difficult to remove. Therefore, non-woven fabric 4 is attached to the side of the heating plate 2 facing the pad 1. The non-woven fabric 4 can be made of polyester fiber, which is heat-resistant and has a smooth surface. It is less likely to stick when melting and ironing the edges of the three-dimensional structure.

[0037] A baffle plate 5 is wrapped around the outside of the heating plate 2, extending along its length and enclosing it. The baffle plate 5 consists of a long side plate 51 and a short side plate 52, connected at their ends to form an L-shaped plate with an L-shaped cross-section. The long side of the baffle plate 5 is attached to the outside of the heating plate 2, while its short side faces the pad 1. The baffle plate 5 can reduce the heat radiation from the heating plate 2 to a certain extent, preventing it from affecting the surrounding environment or objects. It also reduces the heat dissipation rate of the heating plate 2, minimizing heat loss.

[0038] A junction box 6 is fixed on the side of the baffle plate 5. The junction box 6 is equipped with a power supply for connecting the heating rod 3. The wiring 33 connected to the resistance wire 32 inside the heating rod 3 is uniformly connected to the power supply inside the junction box 6, and the power supply uniformly supplies power to several resistance wires 32.

[0039] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
