Description

Technical Field

[0001] This utility model relates to the technical field of foaming and drying equipment, specifically an automatically adjustable foaming and drying oven. Background Technology

[0002] In the foaming molding process or in foamed polymer materials, a honeycomb or porous structure is formed through the addition and reaction of physical or chemical foaming agents. The basic steps of foaming molding are the formation of bubble nuclei, the growth or expansion of bubble nuclei, and the stabilization of bubble nuclei.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN208232182U) discloses a foaming curing oven, comprising a metal cylinder. A support frame is fixed to the outer wall of the bottom end of the metal cylinder by bolts. A motor is fixed to the middle position of the outer wall of the bottom end of the metal cylinder by bolts. A horizontally placed support plate is welded to the bottom end of the outer wall of one side of the metal cylinder. An annular groove is formed on the inner wall of the bottom end of the metal cylinder, and a bearing turntable is engaged with the inner wall of the annular groove. A rectangular frame is fixed to the outer wall of the bearing turntable by bolts, and a pin is provided at the middle position of the outer wall of the top of the rectangular frame. A bearing hole is formed at the middle position of the outer wall of the top of the metal cylinder, and a bearing component is engaged with the inner wall of the bearing hole. The pin is inserted into the inner wall of the bearing component.

[0004] In the aforementioned patent, the rectangular frame is pulled out to facilitate the loading and unloading of materials, making cleaning easier and reducing cleaning difficulty. The operation is simple, resulting in more uniform heating, which is beneficial for improving the curing effect. It also helps to drive airflow and facilitate temperature control. However, during the drying process, the continuous operation of the electric heating lamp inside the metal cylinder will cause the internal air pressure to rise continuously. When the curved door is opened after drying is completed, the high-pressure gas accumulated inside the cylinder may be released instantly, forming a high-speed hot airflow, which poses a safety hazard of burns to the operator from the high-temperature airflow.

[0005] Therefore, this utility model provides an automatically adjustable foaming oven to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This invention provides an automatically adjustable foaming oven, which aims to solve the problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the present invention provides the following technical solution: an automatically adjustable foaming oven, the automatically adjustable foaming oven comprising a base plate, a support frame fixedly mounted on the base plate, an oven body fixedly mounted on the support frame, a first exhaust pipe fixedly mounted on the oven body, a second exhaust pipe fixedly mounted on the first exhaust pipe, and a pressure relief mechanism disposed inside the first exhaust pipe and the second exhaust pipe for automatic exhaust.

[0010] The pressure relief mechanism includes an arc-shaped groove inside the second vent pipe, a first fixed plate fixedly installed inside the first vent pipe, a limiting rod fixedly installed on the first fixed plate, a second fixed plate fixedly installed inside the second vent pipe, a magnetic baffle slidably installed on the limiting rod, a tension spring sleeved on the limiting rod, a vent plate rotatably installed on the limiting rod, an airbag fixedly installed inside the arc-shaped groove, and magnetorheological fluid disposed inside the airbag.

[0011] As a preferred technical solution of this application, the end of the limiting rod away from the first fixing plate is fixedly connected to one side of the second fixing plate, one end of the tension spring is fixedly connected to one side of the first fixing plate, and the other end of the tension spring is fixedly connected to one side of the magnetic baffle.

[0012] As a preferred technical solution of this application, the oven body is provided with a base frame inside, and a rotating shaft is rotatably connected to the bottom inner wall of the oven body.

[0013] As a preferred technical solution of this application, the top of the rotating shaft is fixedly connected to the bottom of the base frame, the top of the base frame is movably connected to a placement rack, and the bottom of the oven body is fixedly connected to a motor.

[0014] As a preferred technical solution of this application, the output end of the motor passes through the oven body, and the output end of the motor is fixedly connected to the end of the rotating shaft away from the base frame.

[0015] As a preferred technical solution of this application, a fan is fixedly connected inside the oven body, and multiple electric baking lamps are fixedly connected inside the oven body, and the electric baking lamps are arranged in a ring array inside the oven body.

[0016] (III) Beneficial Effects

[0017] This invention features a simple structure and convenient operation. Through a pressure relief mechanism, when the internal air pressure of the oven body is too high, the high-pressure air pushes the magnetic baffle outwards. When the insert on the magnetic baffle contacts the outlet plate, the slot on the outlet plate and the insert are not on the same horizontal line. The magnetic baffle approaches the air bladder, and the magnetorheological fluid changes from liquid to solid, increasing its volume. This enlarges the air bladder, causing the outlet plate to rotate until the insert is inserted into the slot. At this point, the high-pressure air moves through the first outlet pipe to the second outlet pipe and is then discharged through the outlet plate. The high-pressure gas accumulated inside the cylinder is released in advance, reducing the risk of operators being burned by the high-temperature airflow. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides an automatically adjustable foaming oven, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the automatic regulating foaming oven includes a base plate 1, a support frame 2 fixedly installed on the base plate 1, an oven body 3 fixedly installed on the support frame 2, a first exhaust pipe 4 fixedly installed on the oven body 3, a second exhaust pipe 5 fixedly installed on the first exhaust pipe 4, and a pressure relief mechanism for automatic exhaust inside the first exhaust pipe 4 and the second exhaust pipe 5.

[0028] The pressure relief mechanism includes an arc-shaped groove 6 inside the second vent pipe 5, a first fixing plate 7 fixedly installed inside the first vent pipe 4, a limiting rod 8 fixedly installed on the first fixing plate 7, a second fixing plate 9 fixedly installed inside the second vent pipe 5, a magnetic baffle 10 slidably installed on the limiting rod 8, a tension spring 11 sleeved on the limiting rod 8, an vent plate 12 rotatably installed on the limiting rod 8, an airbag 13 fixedly installed inside the arc-shaped groove 6, and a magnetorheological fluid 14 disposed inside the airbag 13.

[0029] One end of the limiting rod 8 away from the first fixing plate 7 is fixedly connected to one side of the second fixing plate 9, one end of the tension spring 11 is fixedly connected to one side of the first fixing plate 7, and the other end of the tension spring 11 is fixedly connected to one side of the magnetic baffle 10.

[0030] When using this automatic regulating foaming oven, first place the base plate 1 in a suitable position, then place the material inside the oven body 3. When the internal air pressure of the oven body 3 is too high, the high-pressure air pushes the magnetic baffle 10 outward, causing the magnetic baffle 10 to move along the limit rod 8, while simultaneously stretching the tension spring 11. When the insert on the magnetic baffle 10 contacts the air outlet plate 12, the slot on the air outlet plate 12 and the insert are not on the same horizontal line. When the magnetic baffle 10 approaches the air bladder 13, the magnetorheological fluid 14 changes from liquid to solid, increasing in volume, thereby enlarging the air bladder 13. The vent plate 12 rotates along the limiting rod 8. When the slot on the vent plate 12 rotates to the same horizontal line as the insert on the magnetic baffle 10, the magnetic baffle 10 begins to move until the insert is inserted into the slot. At this time, the high-pressure air moves through the first vent pipe 4 to the inside of the second vent pipe 5 and is then discharged through the vent plate 12. After the high-pressure air in the oven body 3 is discharged, the magnetic baffle 10 is pulled back to its initial position by the tension spring 11. When the magnetic baffle 10 moves away from the air bag 13, the magnetorheological fluid 14 changes from liquid to solid, and its volume decreases, causing the vent plate 12 to rotate in the opposite direction and return to its initial position.

[0031] Furthermore, to facilitate more uniform drying of the materials, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the oven body 3 has a base frame 15 inside, and a rotating shaft 17 is rotatably connected to the bottom inner wall of the oven body 3.

[0032] The top of the rotating shaft 17 is fixedly connected to the bottom of the base frame 15, the top of the base frame 15 is movably connected to the placement rack 16, and the bottom of the oven body 3 is fixedly connected to the motor 18.

[0033] The output end of motor 18 passes through the oven body 3, and the output end of motor 18 is fixedly connected to the end of rotating shaft 17 away from the base frame 15.

[0034] When using this automatic adjustable foaming oven, the material is placed on the placement rack 16, and then the placement rack 16 is placed on the base frame 15. Then, the motor 18 is started, and the output shaft of the motor 18 drives the rotating shaft 17 to rotate synchronously. The rotation of the rotating shaft 17 drives the base frame 15 to rotate synchronously, and the rotation of the base frame 15 drives the placement rack 16 to rotate synchronously, so that the material rotates evenly inside the oven body 3, and the material can be dried more evenly.

[0035] Furthermore, in order to facilitate the control of the temperature inside the oven body 3, such as... Figure 1 , Figure 2 and Figure 3 As shown, a fan 19 is fixedly connected inside the oven body 3, and multiple electric baking lamps 20 are fixedly connected inside the oven body 3. The electric baking lamps 20 are arranged in a ring array inside the oven body 3.

[0036] When using this automatic adjustable foaming oven, after placing the material inside the oven body 3, the material is dried by turning on the electric baking lamp 20. Then, the rotation of the fan 19 can drive the air flow, making it easy to control the temperature.

[0037] 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 the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
