Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, specifically to an industrial-grade 3D printing equipment platform with multi-zone temperature control function. Background Technology

[0002] 3D printing equipment is an additive manufacturing device that builds solid objects by depositing materials layer by layer based on digital model files. Its core principle is to break down a three-dimensional design into two-dimensional sections and use technologies such as fused deposition modeling to achieve physical shaping. Industrial-grade 3D printing equipment is widely used in aerospace, automotive manufacturing, medical and other fields, significantly shortening the research and development cycle and reducing production costs.

[0003] Existing 3D printing equipment suffers from several drawbacks during printing. The printing platform cannot accurately position the heating system to coordinate with the printing process, and it struggles to adapt to the varying temperature requirements of different materials (such as PLA and ABS). This leads to significant differences in cooling rates across different areas of large-sized parts, potentially causing thermal stress, warping, or cracking. Furthermore, the platform's surface plate, which directly supports the printed product, is typically made of tough plastic or highly thermally conductive metal, failing to maintain both sufficient bending flexibility and good thermal conductivity. Therefore, this paper proposes an industrial-grade 3D printing platform with multi-zone temperature control capabilities. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides an industrial-grade 3D printing equipment platform with multi-zone temperature control function.

[0005] The technical solution adopted by this utility model to solve its technical problem is an industrial-grade 3D printing equipment platform with multi-zone temperature control function, including a printing platform, the printing platform including a platform base and a platform plate, the platform plate being installed on the top of the platform base; The platform plate includes a base plate, a heating plate, and a panel. The heating plate and the panel are sequentially arranged on the top of the base plate. A heating groove is formed on the top surface of the heating plate. A polyimide heating element is arranged in the heating groove. At least one set of polyimide heating elements is arranged at equal intervals along the heating groove.

[0006] By adopting the above technical solution, a platform structure with multiple independent temperature zones is provided for industrial-grade 3D printing equipment through a platform plate composed of a base plate, a heating plate, and a panel, and a printing platform formed by the cooperation of the base plate and the platform seat. The panel used to support the printing process has a certain degree of flexibility and high thermal conductivity, which allows the heat from the heating area in the heating plate to be better conducted to the printing material on the top of the panel, thus ensuring the quality of the print.

[0007] Specifically, countersunk holes are provided at equal intervals on the outer periphery of the heating plate, and the countersunk holes of the heating plate are fixed to the platform base by countersunk bolts passing through the base plate.

[0008] By adopting the above technical solution and setting countersunk holes, the surface of the heating plate has good flatness after it is installed with the platform base by countersunk bolts.

[0009] Specifically, L-shaped locking blocks are provided at both ends on one side of the panel, and a corresponding locking slot is provided on one side of the heating plate. A plug is provided on the top of the panel, and corresponding insertion holes are provided on the panel, the L-shaped locking blocks, and the heating plate. The bottom of the plug is inserted into the plugs of the panel, the L-shaped locking blocks, and the heating plate in sequence.

[0010] Specifically, a tension spring is fitted onto the plug, and the two ends of the tension spring are glued and fixed to the plug and the panel, respectively.

[0011] By adopting the above technical solution, the L-shaped card block and card slot make it easy for the panel to be inserted into the heating plate, so as to ensure the stability of the panel on the heating plate during printing. The insertion of the plug provides auxiliary positioning. When disassembling, the panel can be quickly disassembled by pulling out the plug and then pulling the panel out horizontally. It is flexible and convenient to use, and makes it easier for personnel to load and unload materials.

[0012] Specifically, the panel includes a PPS panel layer, and steel needles for heat conduction are embedded at equal intervals at the bottom of the PPS panel layer. The diameter of the top of the steel needles is larger than the diameter of the bottom, and a frosted layer is provided on the top surface of the PPS panel layer.

[0013] By adopting the above technical solution, the frosted layer can improve the anti-slip properties of the top surface of the panel to the bottom surface of the printed product. If a high degree of flatness of the bottom surface of the printed product is required, a panel without a frosted layer and with a glossy top can be selected. Alternatively, during printing, an additional support structure can be printed between the panel and the printed product using printing material to isolate the direct contact between the printed product and the panel. The actual printing settings are determined according to the requirements of the printed product.

[0014] Specifically, the base plate and the heating plate are provided with equally spaced wiring openings for the polyimide heating element.

[0015] By adopting the above technical solution, the wiring holes opened on the base plate and heating plate facilitate the passage of the polyimide heating element's wiring to connect to the external temperature control equipment.

[0016] The beneficial effects of this utility model are as follows: The platform plate, composed of a base plate, a heating plate, and a panel, along with the printing platform formed by their cooperation with the platform base, provides an industrial-grade 3D printing equipment with a platform structure featuring multiple independent temperature zones. The panel, which supports the printing process, possesses both flexibility and high thermal conductivity, allowing heat from the heating area of ​​the heating plate to be better transferred to the printing material on top of the panel, ensuring print quality. By setting several independent polyimide heating elements on the top of the heating plate, heating can be selectively activated in localized areas based on the position and size of the printed product, reducing the heating energy consumption of small-sized printed products. Furthermore, when printing products using mixed materials, the heating energy can be controlled separately. This invention utilizes polyimide heating elements to adapt to the temperature differences of different printing materials. When the printed product needs to be removed from the platform, if some areas of the printed product stick to the platform, the operator can individually control the polyimide heating element in that area to heat the sticky area, promoting the separation of the sticky area. During this process, the heating temperature is controlled according to the melting point of the printing material, and it is necessary to avoid heating the temperature above the melting point of the printing material. This application is flexible and convenient to use. Through the independent heating design of multiple areas, it can effectively solve the problem that the printing platform cannot accurately position the heating to cooperate with the printing during the existing printing process, and cannot adapt well to the temperature difference requirements of different materials. This can easily lead to large differences in the cooling rate of different areas of large-sized parts, which can easily generate thermal stress and cause warping or cracking.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-7 As shown, the industrial-grade 3D printing equipment platform with multi-zone temperature control function of this utility model includes a printing platform 1, which includes a platform base 11 and a platform plate 12, and the platform plate 12 is installed on the top of the platform base 11. The platform plate 12 includes a base plate 121, a heating plate 122, and a panel 123. The heating plate 122 and the panel 123 are sequentially disposed on the top of the base plate 121. A heating groove 1221 is formed on the top surface of the heating plate 122. A polyimide heating element 1222 is disposed in the heating groove 1221. At least one set of the polyimide heating elements 1222 is disposed and arranged at equal intervals along the heating groove 1221.

[0021] The present invention also includes countersunk holes 1225 evenly spaced around the outer periphery of the heating plate 122, and the countersunk holes 1225 of the heating plate 122 are installed and fixed to the platform base 11 through the base plate 121 by countersunk bolts.

[0022] When in use, the countersunk hole 1225 allows the heating plate 122 to be installed on the platform base 11 with countersunk bolts, resulting in a smooth surface on the heating plate 122.

[0023] The present invention further includes that L-shaped locking blocks 1231 are respectively provided at both ends of one side of the panel 123, and a locking groove 1223 corresponding to the L-shaped locking blocks 1231 is provided on one side of the heating plate 122. A plug 1232 is provided at the top of the panel 123. A corresponding insertion hole 1224 is provided on the panel 123, the L-shaped locking blocks 1231 and the heating plate 122. The bottom of the plug 1232 is sequentially inserted into the plug 1232 of the panel 123, the L-shaped locking blocks 1231 and the heating plate 122.

[0024] The present invention also includes a tension spring 1233 sleeved on the plug 1232, and the two ends of the tension spring 1233 are respectively glued and fixed to the plug 1232 and the panel 123.

[0025] In use, the L-shaped locking block 1231 and the slot 1223 facilitate the easy insertion of the panel 123 into the heating plate 122, ensuring stability on the heating plate 122 during printing. The insertion of the plug 1232 provides auxiliary positioning. When disassembling, the panel 123 can be quickly removed by pulling out the plug 1232 and then pulling it out laterally. The panel 123 is flexible and convenient to use, making it easier for personnel to load and unload materials.

[0026] The present invention also includes that the panel 123 includes a PPS panel layer 1234, and steel needles 1235 for heat conduction are embedded at equal intervals in the bottom of the PPS panel layer 1234. The diameter of the top of the steel needles 1235 is larger than the diameter of the bottom. A frosted layer 1236 is provided on the top surface of the PPS panel layer 1234.

[0027] When in use, the frosted layer 1236 helps to improve the anti-slip properties of the top surface of the panel 123 to the bottom surface of the printed product. If a high degree of flatness of the bottom surface of the printed product is required, a panel 123 without the frosted layer 1236 and with a glossy top can be selected. Alternatively, during printing, an additional support structure can be printed between the panel 123 and the printed product using printing material to isolate the direct contact between the printed product and the panel 123. The actual printing settings are determined according to the needs of the printed product.

[0028] The present invention also includes that the base plate 121 and the heating plate 122 are provided with wire holes at equal intervals for wiring of the polyimide heating element 1222.

[0029] In use, the wiring openings on the base plate 121 and heating plate 122 facilitate the passage of the polyimide heating element 1222's wiring to connect to the external temperature control equipment.

[0030] In use, the printing platform 1 is bolted to the workbench or frame of the industrial-grade 3D printing equipment, and the power supply components around the site provide power to the polyimide heating element 1222. The polyimide heating element 1222 is equipped with a temperature controller or connected to the temperature control unit of the 3D printing equipment so that the printing personnel can control the heating of the polyimide heating element 1222. During use, the panel 123 is placed on top of the heating plate 122, and the L-shaped locking block 1231 on the side of the panel 123 is pushed into the slot 1223 of the heating plate 122. Then, the panel 123 and the heating plate 122 are vertically connected using the plug 1232 for simple positioning. Subsequently, industrial-grade 3D printing equipment performs printing on the panel 123. During this process, the printer activates the heating of the polyimide heating element 1222 within the area to be printed, based on the material being printed and the size range of the printed product. The heating temperature of the polyimide heating element 1222 is set by the printer according to the actual printing material. The steel needle 1235 facilitates better upward heat conduction from the polyimide heating element 1222 to the product. After printing, the plug 1232 can be pulled out to quickly remove the panel 123. By applying a certain force to the panel 123, it can bend slightly, facilitating the separation of the printed product from the panel 123, allowing the printed product to be removed. If a portion of the printed product sticks to the platform, the operator can individually control the polyimide heating element 1222 in that area to heat the sticky area, promoting heat separation of the sticky area. It is flexible and convenient to use and suitable for printing various types of materials.

[0031] Furthermore, the steel needles 1235 in the panel 123 are pre-embedded before the PPS panel layer 1234 is heated and cooled. After the extruded plastic cools, the steel needles 1235 are fixed in the panel 123, so that the panel 123 as a whole has good vertical support. After removal, based on the plastic flexibility of the PPS panel layer 1234, the panel 123 can be bent under certain pressure, which facilitates the removal of the printed material.

[0032] Furthermore, the polyimide heating element 1222 has a size of 10mm*20mm to 50mm*100mm, and the polyimide heating element 1222 is laid in an array in the heating groove 1221. The number of laying elements is set according to actual needs. After the panel 123 is placed on the heating plate 122, the bottom surface of the panel 123 and the steel needle 1235 are in contact with the polyimide heating element 1222.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
