Description

Technical Field

[0001] This utility model relates to the field of epoxy curing agent production technology, and in particular to a paint film drying oven. Background Technology

[0002] A paint film, also known as a coating film, is a solid continuous film formed by one or more coatings applied to a substrate. It is usually composed of multiple coatings, the specific number of which depends on the requirements of the object being coated. Generally, it includes a primer layer, an intermediate coating layer, and a topcoat layer. After adding a curing agent, the paint film needs to be dried and cured, so an oven is required.

[0003] A search revealed a Chinese patent for a temperature-controlled rotary internal circulation adjustable oven (authorization announcement number CN211823652U), comprising a base plate, a DHG-9030 oven body, a rotating disk, and a door. The DHG-9030 oven body is fixedly mounted on the top of the base plate via a shock-absorbing device. A rotating disk is fixedly mounted at the center of the bottom of the DHG-9030 oven body. A YRF60 servo motor is fixedly mounted at the center of the bottom of the DHG-9030 oven body, with its output end fixedly connected to the rotating disk. The YRF60 servo motor is electrically connected to the DHG-9030 oven body. A heating plate is fixedly mounted on the top of the DHG-9030 oven body. Although this invention can buffer external vibrations through the shock-absorbing device to prevent vibrations from affecting the DHG-9030 oven body.

[0004] However, the above-mentioned device still has some drawbacks in actual use. The most obvious one is that the heating plate used in the oven is used to heat the object. However, when the heating plate is damaged, the staff needs to remove and replace the entire heating plate, which will increase the maintenance cost of the oven. In addition, due to the high temperature after drying, the staff is prone to burns when changing materials. Utility Model Content

A hinge is provided between the installation seat and the fixing member. The installation seat and the fixing member are connected by the hinge. One end of the heating core rod is engaged with the insertion hole, and the other end of the heating core rod is in contact with the inner wall of the fixing member.

[0007] By adopting the above technical solution, when the heating source is damaged, the staff only needs to use the fixing components to remove the heating core rod in the corresponding mounting base and then replace it with a new heating core rod, without having to replace the entire heating source.

[0008] In a preferred embodiment, the oven body is provided with a support component inside. The support component includes three high-temperature insulating frames disposed inside the oven body.

[0019] By adopting the above technical solution and using a blower, the circulation speed of hot air in the oven body can be increased, thereby improving drying efficiency.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1. In this utility model, the paint film is heated and dried by the continuous heating of multiple heating cores.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] Reference Figure 1-4 A paint film drying oven includes an oven body 1. A mounting frame 10 is fixedly installed inside the oven body 1. Air inlet slots 11 are equidistantly spaced inside the mounting frame 10. Mounting seats 12 are fixedly connected inside the mounting frame 10, located between two air inlet slots 11. Each mounting seat 12 has a heating core rod 13 inside. One side of each mounting seat 12 has an insertion hole 17 for engaging with the heating core rod 13. The other side of each mounting seat 12 has a fixing member 14. A hinge 16 connects the mounting seat 12 and the fixing member 14. One end of the heating core rod 13 engages with the insertion hole 17. The other end of 13 is attached to the inner wall of the fixing part 14. When the paint film is dried and cured after the fixing agent is added, the staff can place the paint film flat in each wire mesh frame 9. The paint film is heated and dried by the continuous heating of multiple heating cores 13. Compared with the traditional electric heating plate heating method, this solution uses multiple independently operating heating cores 13 as a substitute. When the heating source is damaged, the staff only needs to use the fixing component to remove the heating core 13 in the corresponding mounting base 12 and then replace it with a new heating core 13. There is no need to replace the entire heating source, which can reduce the subsequent maintenance cost of the oven body 1.

[0030] Specifically, the oven body 1 has a supporting component inside, which includes three high-temperature insulating frames 8 installed inside the oven body 1. These high-temperature insulating frames 8, made of high-temperature resistant ceramic and aluminum silicate materials, maintain good heat insulation performance in high-temperature environments. This allows workers to easily remove the high-temperature insulating frames 8 from the oven body 1 after the drying process, reducing the risk of burns. Each high-temperature insulating frame 8 has a wire mesh frame 9 fixedly connected inside. The high-temperature insulating frames 8 are also made of high-temperature resistant ceramic and aluminum silicate materials. The top of the mounting base 12 has a fixing component, which includes a fixing connection... A half-screw 15 is connected to the fixing part 14 and the mounting base 12 on one side. A nut 18 is threaded between the two half-screws 15. By using the nut 18, the two half-screws 15 can be fixed together, thereby achieving the purpose of fixing the heating core rod 13. At the same time, it can facilitate the disassembly of the heating core rod 13. The oven body 1 has slots 6 on both sides of the high temperature insulation frame 8. The slots 6 have clips 7 slidably installed inside. The two clips 7 are fixedly connected to the two sides of the high temperature insulation frame 8, which can play a certain positioning role, making it easier to insert the high temperature insulation frame 8 into the oven body 1.

[0031] Specifically, the oven body 1 has a hinged door 2 on its outer side, and a viewing window is fixedly installed inside the door 2. The viewing window allows staff to easily check the drying status inside the oven body 1. A temperature controller is fixedly installed inside the oven body 1. Through the setting of the temperature sensor, the drying temperature inside the oven body 1 can be monitored and the temperature value can be displayed on the control panel 3. The control panel 3 is fixedly installed on the outer side of the oven body 1. The control panel 3 can control the start and stop of the blower 5. A temperature control knob 4 is fixedly installed on the outer side of the oven body 1. The blower 5 is fixedly installed at the bottom of the oven body 1. The use of the blower 5 can increase the circulation speed of hot air inside the oven body 1 and improve the drying efficiency. There are air vents arrayed on the rear side of the oven body 1 to stabilize the air pressure inside the oven body 1.

[0032] Working principle: First, after the paint film is dried and cured with the fixative, the operator can open the oven door 2 and place the paint film flat in each wire mesh rack 9. Then, close the oven door 2 and start the blower 5 and heating core rods 13 through the control panel 3. Through the continuous heating of multiple heating core rods 13, the paint film is heated and dried. The drying temperature inside the oven body 1 can be monitored by the temperature sensor and the temperature value can be displayed on the control panel 3. At the same time, the heating temperature of the heating core rods 13 can be adjusted by using the temperature control knob 4. When the heating core rods 13 generate heat... When damaged, the operator can unscrew the nut 18 at the corresponding mounting base 12 to detach the two half screws 15, thereby disassembling the heating core rod 13 and facilitating the installation of a new heating core rod 13 without replacing the entire heating source. This reduces the subsequent maintenance costs of the oven body 1. Furthermore, the high-temperature insulation frame 8, made of high-temperature resistant ceramic and aluminum silicate materials, maintains good heat insulation performance in high-temperature environments. After the drying process is completed, the operator can easily remove the high-temperature insulation frame 8 from the oven body 1 to reduce the risk of burns.
