Technical Field

[0001] This utility model relates to the field of liquid silicone technology, and in particular to a liquid silicone foaming and baking device. Background Technology

[0002] The main function of liquid silicone foaming and baking is to form a foam structure with a certain density and elasticity through heating and foaming reaction.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0020] Please see Figure 1-5 This utility model provides a technical solution: a liquid silicone foaming and baking device, including an oven shell 1, a sealing door 2 movably disposed at the front end of the oven shell 1, a material loading mechanism disposed on the inner side of the sealing door 2, a high-temperature resistant sealing sleeve 21 fixedly installed on the inner side frame of the sealing door 2, a driving mechanism for moving the sealing door 2 disposed on one outer surface of the oven shell 1, support legs 6 fixedly installed on both sides of the lower surface of the oven shell 1, and a baking mechanism disposed inside the oven shell 1.

[0021] In this embodiment, a sealing door 2 is movably installed on the front side of the oven shell 1, and a material loading mechanism is provided on one side of the sealing door 2. At the same time, a driving mechanism for moving the sealing door 2 is provided on the outer surface of one side of the oven shell 1. Under the action of the driving mechanism, the sealing door 2 and the material loading mechanism can freely enter and exit the interior of the oven shell 1. Meanwhile, a baking mechanism is provided inside the oven shell 1. Under the action of the baking mechanism, the material loading mechanism carrying liquid silicone can be baked with hot air foaming. The entire baking process is fully automatic, reducing human intervention and is convenient and fast. At the same time, when removing the product, it is not necessary to manually reach into the interior of the oven shell 1 to remove the product, avoiding the risk of workers being burned.

[0022] Specifically, the high-temperature resistant sealing sleeve 21 is a high-temperature resistant polytetrafluoroethylene component, and the inner surface of the high-temperature resistant sealing sleeve 21 is in contact with the outer surface of the oven shell 1.

[0023] Specifically, the material loading mechanism includes several material loading boxes 3 fixedly installed on the inner surface of the sealing door 2. The material loading boxes 3 are arranged vertically from top to bottom. Each material loading box 3 has two symmetrically distributed material loading slots 31 on its inner side, and each material loading slot 31 has a semiconductor cooling chip 32 embedded at its bottom.

[0024] In this embodiment, by setting a material loading mechanism inside the sealing door 2, when it is necessary to foam and bake the liquid silicone, the liquid silicone is first placed inside the material loading tank 31, and then the semiconductor cooling chip 32 embedded at the bottom of the material loading tank 31 is controlled externally to cool the liquid silicone to 10-15°C. Its function is to increase its viscosity and suppress bubble migration. After the cooling is completed, the material loading box 3 carrying the liquid silicone is driven by the driving mechanism to enter the oven shell 1 for baking.

[0025] Specifically, the drive mechanism includes a reversible motor 51 fixedly installed on the outer surface of one side of the oven shell 1, and a heat insulation pad 53 fixedly installed between the reversible motor 51 and the oven shell 1. A one-way lead screw 5 is fixedly installed on the output shaft of the reversible motor 51. A movable kit 52 is screwed onto the outer surface of the one-way lead screw 5. The movable kit 52 has a threaded groove adapted to the one-way lead screw 5 inside. The other side of the movable kit 52 is fixedly connected to the side surface of the sealing door 2. Several guide rods 11 are fixedly installed from top to bottom on both sides of the interior of the oven shell 1. The guide rods 11 are distributed on both sides of the material box 3. A collar 33 is movably sleeved on the outer surface of each guide rod 11. The other side of the collar 33 is fixedly connected to the outer surface of the material box 3. Several positioning sleeves 22 are fixedly installed from top to bottom on the inner surface of the sealing door 2. The positions of the positioning sleeves 22 and the guide rods 11 are corresponding and adapted.

[0026] In this embodiment, a drive mechanism for moving the sealing door 2 is provided on the outer surface of one side of the oven shell 1. When liquid silicone is placed inside the material box 3, the forward and reverse motor 51 is started by the external controller. Under the action of the forward and reverse motor 51, the one-way screw 5 rotates accordingly, thereby driving the movable kit 52 to move on the outer surface of the one-way screw 5, thereby driving the sealing door 2 and the material loading mechanism provided on its inner side to move and enter the interior of the oven shell 1. The guide rods 11 and collars 33 are provided on both sides inside the oven shell 1 to prevent the material box 3 and the sealing door 2 from deviating during the movement, thus making the movement more stable.

[0027] Specifically, the baking mechanism includes a hot air blower 4 fixedly installed on the top rear side of the oven shell 1. The lower end of the hot air blower 4 is fixedly and sealed with a fixed air guide pipe 41. The fixed air guide pipe 41 is fixedly installed on the inner rear side of the oven shell 1. Several ventilation pipes 42 are fixedly installed at the front end of the fixed air guide pipe 41. Each ventilation pipe 42 has a branch jet shell 43 at both ends. One side of the branch jet shell 43 is provided with a 45-degree slope to the horizontal. Several nozzles 44 are fixedly installed on the slope of one side of the branch jet shell 43. The branch jet shell 43 is located on the side and above the material loading mechanism. The branch jet shell 43, the fixed air guide pipe 41, and the ventilation pipes 42 are interconnected. Two strip-shaped ventilation slots 12 are opened on the rear side of the oven shell 1. Strip-shaped filter screens 13 are fixedly installed inside the strip-shaped ventilation slots 12.

[0028] In this embodiment, a baking mechanism is provided on the rear side of the oven shell 1. When the material carrier 3 carries liquid silicone into the oven shell 1, the hot air blower 4 is started by the external controller. The hot air passes through the fixed air guide duct 41, the ventilation duct 42, and the branch jet shell 43 in sequence and is sprayed out by the nozzle 44. Since the nozzle 44 is installed on the inclined surface of the branch jet shell 43 and the branch jet shell 43 is located on both sides of the material carrier 3 at an angle, the liquid silicone placed in the material carrier 31 can be baked in all directions. The strip-shaped ventilation groove 12 and the strip-shaped filter screen 13 provided on the rear side of the oven shell 1 can discharge gas and prevent external debris from entering the interior of the oven shell 1. After baking, the sealing door 2 is moved by the drive mechanism, so that the material carrier mechanism exits the interior of the oven shell 1, and the staff can take out the material.

[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
