Description

Technical Field

[0001] This utility model relates to the technical field of thermoplastic powder spraying and melting devices, and in particular to a thermoplastic powder spraying and melting device. Background Technology

[0002] During the production of metal parts for home appliances, a spraying device is needed to perform surface treatment on the metal parts of the appliances—the thermoplastic powder is sprayed onto the surface of the metal parts, and the thermoplastic powder solidifies on the metal surface after being heated to form a protective layer.

[0003] The storage containers of some existing common thermoplastic powder melt spraying devices are generally used for storing materials and have relatively simple functions. However, sometimes, in order to improve performance or meet specific needs, some additives or other materials may be added. These materials need to be mixed before heating. If the mixing is not in place, it will affect the smoothness of the protective layer. For example, a thermoplastic powder melt spraying device with publication number CN106111383B is described. Therefore, it is necessary to design a thermoplastic powder melt spraying device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a thermoplastic powder spraying and melting device.

[0006] A thermoplastic powder spraying and melting device includes a high-pressure powder container body, a can lid, a connecting pipe, and a spray gun. The upper end of the high-pressure powder container body is fixedly connected to a mounting plate. The high-pressure powder container body is provided with a mixing mechanism for mixing. The mixing mechanism includes a liquid storage box fixedly connected to the can lid. A motor is mounted on the upper end of the liquid storage box via a mounting bracket. The output shaft of the motor is fixedly connected to a rotating pipe. A connecting rod is fixedly connected to the lower end of the rotating pipe. Multiple stirring blades are fixedly connected to the side wall of the connecting rod. The can lid is provided with a preheating mechanism for preheating the material.

[0007] Preferably, the preheating mechanism includes a circulating pump and a heating box fixedly connected to the mounting plate. A temporary storage box is fixedly connected to the lower end of the high-pressure powder container body. The temporary storage box is provided with a rotating tube and a connecting tube communicating with its interior. The rotating tube is connected to the rotating tube through two flow tubes. An inlet hole is opened on the side wall of the rotating tube.

[0008] Preferably, two rotating plates are fixedly connected to the side wall of the flow tube, and the rotating tube is rotatably connected to the temporary storage box.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-3A thermoplastic powder spraying and melting device includes a high-pressure powder container body 1, a can lid 2, a connecting pipe 9, and a spray gun 10. The high-pressure powder container body 1 is an existing high-pressure container. An installation plate is fixedly connected to the upper end of the high-pressure powder container body 1. A mixing mechanism for mixing principle is provided inside the high-pressure powder container body 1. The mixing mechanism includes a liquid storage box 3 fixedly connected to the can lid 2. A motor 4 is mounted on the upper end of the liquid storage box 3 through a mounting bracket. A rotating pipe 6 is fixedly connected to the output shaft of the motor 4. A connecting rod 7 is fixedly connected to the lower end of the rotating pipe 6. Multiple stirring blades 8 are fixedly connected to the side wall of the connecting rod 7.

[0021] The can lid 2 is equipped with a preheating mechanism for preheating materials. The preheating mechanism includes a circulating pump 15 and a heating box 5 fixedly connected to the mounting plate. The heating box 5 contains an electric heater, such as an electric heating wire or an electric heating rod, which can heat the heating oil. The lower end of the high-pressure powder container body 1 is fixedly connected to a temporary storage box 11. The temporary storage box 11 is equipped with a rotating tube 12 and a connecting tube 16 that communicate with its interior. The rotating tube 12 is connected to the rotating tube 6 through two flow tubes. The rotating tube 6 has a liquid inlet hole on its side wall.

[0022] In this invention, two rotating plates 13 are fixedly connected to the side wall of the flow tube. The rotating plates 13 can stir the material and improve the stirring effect. The rotating tube 12 is rotatably connected to the temporary storage box 11.

[0023] In this utility model, a temperature controller 18 is fixedly connected to the upper end of the mounting plate. The temperature controller 18 is model P8100-22100020. A temperature sensor 14 is provided on the side wall of the high-pressure powder container body 1. The temperature sensor 14 can be a monitoring sensor of model WZP-230. Its probe is inserted into the container to monitor the temperature of the material in the container and avoid overheating of the material.

[0024] In this utility model, a display 19 is installed on the upper end of the mounting plate, and an alarm 17 is installed on the upper end of the mounting plate. The alarm 17 can be an alarm device of the brand name Deyansi, which can sound an alarm when the temperature is too high, reminding people that the material has reached the preset temperature of the temperature controller 18.

[0025] In this utility model, motor 4 is a servo motor. Motor 4 can be a drive device with model number 130ZFMA1-0003CBNM. The output shaft speed is controllable, thereby changing the mixing speed of the material. The cross-section of the flow pipe is U-shaped, and the horizontal part of the flow pipe can stir the material, thereby achieving a certain stirring effect.

[0026] When in use, remove the can lid 2 and pour various materials into the container. You can start the motor 4. The output shaft of the motor 4 drives the rotating tube 6 to rotate. The rotating tube 6 drives the connecting rod 7 to rotate. The connecting rod 7 drives multiple stirring blades 8 to rotate, which can stir and mix the materials, making the materials more uniform. This can make the materials entering the spray gun 10 more uniform and improve the spraying effect.

[0027] By starting the circulating pump 15 and the heating box 5, the circulating pump 15 continuously sends the heating oil in the heating box 5 into the storage box 3. The heating oil in the storage box 3 enters the rotating tube 6 and then enters the rotating tube 12 through two flow tubes. The heating oil enters the temporary storage box 11 from the rotating tube 12 and finally returns to the heating box 5 through the connecting tube 16. During the process, the heating oil flowing in the flow tube can preheat the material, making it easier for the raw material to flow when it enters the spray gun 10, which helps to form a more uniform protective layer.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and practical concept of the present utility model, should be included within the protection scope of the present utility model.
