Description

Technical Field

[0001] This utility model relates to a circulating air guide structure for a coating machine oven, and more particularly to a circulating air guide structure for a coating machine oven. Background Technology

[0002] The coating machine oven is one of the core pieces of equipment in the coating production line. It is essentially a controllable high-temperature drying system, which is specifically designed to quickly and uniformly dry and cure coated materials (such as films, paper, fabrics, etc.).

[0003] In the production of coated materials, hot air drying is a crucial step in ensuring coating quality. Traditional drying systems typically use hot air convection to dry the coated material, ensuring uniform curing of the coating on the material surface. During operation, air enters the oven through external air ducts and inlet pipes, and after being heated by heating plates, it dries the material. However, this unidirectional airflow can lead to significant heat loss through the oven openings, reducing drying efficiency and increasing energy consumption.

[0004] Therefore, a circulating air guide structure for the coating machine oven is needed. Utility Model Content

[0005] In order to overcome the shortcomings of existing drying systems, which may cause a large amount of heat to be lost through the opening of the oven due to the unidirectional airflow during operation, thereby reducing drying efficiency and increasing energy consumption, this utility model provides a circulating air guide structure for a coating machine oven.

[0006] The technical solution of this utility model is as follows: a circulating air guide structure for a coating machine oven, including an oven body, heating plates, connecting pipes, air inlet pipes, and a mounting box. Heating plates are installed on both the left and right sides inside the oven body. A mounting box is installed on the top of the oven body. The other end of the connecting pipe is connected to one side of the heating plate. Connecting pipes are connected and communicated on both the left and right sides of the mounting box. An air inlet pipe is connected and communicated on the front side of the mounting box. It also includes a suction pipe, an air pump, a baffle, and a cylinder. A suction pipe is connected and communicated on the bottom of the mounting box. An air pump is installed on the suction pipe. A baffle is slidably installed inside the mounting box. The baffle can block the air outlet at the upper end of the suction pipe. A cylinder is installed on the top of the oven body. The telescopic rod of the cylinder is connected to the baffle.

[0007] As a preferred technical solution of this utility model, it also includes a fixed frame, a guide rod, a bidirectional screw, a dual-axis motor, a sliding plate, a limiting plate, and a placement plate. Fixed frames are installed on both the left and right sides of the oven body. A guide rod is fixedly connected to the fixed frame on the right side. A dual-axis motor is installed on the fixed frame on the right side. The two output shafts of the dual-axis motor are connected to the bidirectional screw via couplings. The end of the bidirectional screw away from the dual-axis motor is rotatably connected to the fixed frame. A sliding plate is threadedly connected to the bidirectional screw. Two sliding plates are slidably arranged on the guide rod. Two sliding plates at the same horizontal height are fixedly connected to two limiting plates. A placement plate is fixedly connected to the front side of the lower limiting plate.

[0008] As a preferred technical solution of this utility model, it also includes a temperature detector and a warning light. The temperature detector is installed on the top of the oven body, and the warning light is installed on the top of the oven body. The warning light is electrically connected to the temperature detector.

[0009] As a preferred technical solution of this utility model, it also includes a sound generator, which is installed on the top of the oven body and is electrically connected to the temperature detector.

[0010] As a preferred technical solution of this utility model, one end of the air inlet pipe is provided with threads.

[0011] As a preferred technical solution of this utility model, a rubber block is provided on the limiting plate.

[0012] Compared with the prior art, this utility model provides a circulating air guide structure for a coating machine oven, which has the following beneficial effects: 1. When the air pump is started, the air pump draws air from inside the oven body and draws the used hot air into the installation box to realize the circulation of hot air, thereby accelerating the temperature rise and improving the drying efficiency.

[0013] 2. When the screw rotates, it drives the sliding plates to move in opposite directions. When the sliding plates move, they drive the limiting plates to move closer to each other in sync, thereby blocking the openings on the front and back sides of the oven body and effectively reducing heat loss.

[0014] 3. When the detected temperature exceeds the safe operating range, the temperature detector will trigger an alarm light to remind the operator to check the equipment in time to prevent abnormal temperature from causing product quality problems or safety accidents.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0025] Example 1: A circulating air guide structure for a coating machine oven, please refer to... Figures 1-8The oven includes an oven body 1, heating plates 2, connecting pipes 3, air inlet pipes 5, and mounting boxes 4. Heating plates 2 are installed on both the left and right sides inside the oven body 1. Mounting boxes 4 are installed on the top of the oven body 1. The other end of the connecting pipes 3 is connected to one side of the heating plates 2. The mounting boxes 4 are connected to and connected to the connecting pipes 3 on both the left and right sides. The air inlet pipes 5 are connected to and connected to the front of the mounting boxes 4. The suction pipes 6 are connected to and connected to the bottom of the mounting boxes 4. An air pump 7 is installed on the suction pipes 6. A baffle 8 is slidably installed inside the mounting boxes 4. The baffle 8 can block the air outlet at the top of the suction pipes 6. A cylinder 9 is installed on the top of the oven body 1. The telescopic rod of the cylinder 9 is connected to the baffle 8. One end of the air inlet pipe 5 is threaded to facilitate quick and reliable connection and sealing with the external fresh air duct. A rubber block is installed on the limiting plate 15 to protect the coating material and increase friction to prevent slippage.

[0026] When the coated material needs to be dried, connect the external air pipe to the air inlet pipe 5. After ensuring a secure connection, transport the coated material to be dried into the oven body 1. Start the external power source to draw air into the mounting box 4 through the external air pipe and air inlet pipe 5, and then transport it to the heating plate 2 through the air inlet pipe 5. The air is heated as it flows through the heating plate 2. The heated air is then sprayed from the heating plate 2 into the oven body 1 to dry the coated material. During the drying process, the cylinder 9 can be started to drive the baffle 8 to move upward and open the air outlet at the top of the suction pipe 6. At the same time, the air pump 7 is started. The air pump 7 draws air from inside the oven body 1 and draws the used hot air into the mounting box 4 to achieve the circulation of hot air, thereby accelerating the temperature rise and improving the drying efficiency.

[0027] Example 2: Based on Example 1, please refer to... Figure 1 , Figure 6 and Figure 7 The oven body 1 has fixed frames 10 installed on both the left and right sides. A guide rod 11 is fixedly connected to the right fixed frame 10. A dual-axis motor 13 is installed on the right fixed frame 10. The two output shafts of the dual-axis motor 13 are connected to bidirectional screws 12 through couplings. The end of the bidirectional screw 12 away from the dual-axis motor 13 is rotatably connected to the fixed frame 10. A sliding plate 14 is threadedly connected to the bidirectional screw 12. Two sliding plates 14 are slidably arranged on the guide rod 11. The two sliding plates 14 at the same horizontal height are fixedly connected to two limiting plates 15. A placement plate 16 is fixedly connected to the front side of the lower limiting plate 15.

[0028] After the coating material to be dried is conveyed into the oven body 1, the dual-axis motor 13 is started. The dual-axis motor 13 drives two bidirectional screws 12 to rotate simultaneously. When the screws rotate, they drive the sliding plate 14 to move in opposite directions. When the sliding plate 14 moves, it drives the limiting plate 15 to move closer to each other in sync, thereby blocking the openings on the front and rear sides of the oven body 1 and effectively reducing heat loss.

[0029] Please see Figure 1 and Figure 8 A temperature detector 17 is installed on the top of the oven body 1. An alarm light 18 is also installed on the top of the oven body 1. The alarm light 18 is electrically connected to the temperature detector 17. A sounder 19 is installed on the top of the oven body 1. The sounder 19 is electrically connected to the temperature detector 17. When the detected temperature exceeds the safe operating range, the temperature detector 17 will also trigger the sounder 19 to emit an alarm sound, providing an auditory alarm.

[0030] When drying the coating material, turn on the temperature detector 17 to monitor the temperature inside the oven body 1 in real time. When the detected temperature exceeds the safe operating range, the temperature detector 17 will trigger the warning light 18 to light up, reminding the operator to check the equipment in time to prevent abnormal temperature from causing product quality problems or safety accidents.

[0031] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
