Description

Technical Field

[0001] The utility model relates to the technical field of paint stripping furnaces, in particular to a thermal paint stripping furnace. Background Art

[0002] A pyrolysis paint stripping furnace is a device used to remove coatings from the surface of an object. It is often used to remove objects coated with paint, coatings or powder coatings, such as metal workpieces, plastic products, etc. The coating becomes brittle after pyrolysis and loses its adhesion, and can be removed from the surface of the object by physical methods (such as scraping or brushing).

[0003] When using physical methods to treat brittle coatings, the heated object must first be cooled. During cooling, since the paint stripping furnace still retains residual heat after shutdown, it is not conducive to the cooling of the object, so the object needs to be taken out of the paint stripping furnace, and the high-temperature object may cause burns when it is manually taken out. In view of this, the utility model proposes a thermal paint stripping furnace. Utility Model Content

[0031] Example

[0032] like Figure 1 As shown, the utility model provides a thermal paint stripping furnace, comprising a furnace body 1 and a furnace door hinged on one side thereof, the furnace door being fixed with a door lock. A base frame 11 is provided at the bottom of the furnace body 1, and the base frame 11 is used to raise the bottom position of the furnace body 1. A placing rack 2 for placing objects is provided at the bottom of the placing rack 2, and a plurality of moving wheels 21 are installed at the bottom of the placing rack 2 for moving the objects.

[0033] For details, please refer to Figure 1 and Figure 2The paint stripping furnace also includes a support mechanism 3 arranged on one side of the furnace door of the furnace body 1 for driving the placement rack 2 to rise and fall. The support mechanism 3 includes a bottom plate 31, a top plate 32, and a support rod 33. The bottom plate 31 is fixedly connected to one side of the bottom frame 11, and the top plate 32 is arranged above the bottom plate 31. Multiple groups of support rods 33 are rotatably connected between the bottom plate 31 and the top plate 32, and the multiple groups of support rods 33 are parallel to each other. The support rods 33 are used to support the top plate 32. At the same time, when the top plate 32 moves, the multiple groups of support rods 33 keep parallel to each other and deflect synchronously, and drive the height of the top plate 32 to change. The support mechanism 3 also includes a support plate 34, a slider 35, a fixed block 36, a sliding column 37, and a connecting plate 38. The support plate 34 is fixedly connected to the bottom of the top plate 32. When the top plate 32 moves to the lowest position, the bottom of the support plate 34 contacts the bottom plate 31 for support. Multiple groups of sliders 35 are all slidably connected to the support plate 34. The slider 35 is a T-shaped structure to make it slide stably, and limit blocks are set on both sides to prevent the slider 35 from sliding off the support plate 34. The fixed block 36 is installed on the side of the slider 35 away from the support plate 34, and the fixed block 36 moves synchronously with the slider 35. The sliding column 37 is slidably connected to the fixed block 36. The sliding column 37 is a T-shaped structure to prevent it from falling off, so that the sliding column 37 slides relative to the support plate 34, and the slider 35 and the fixed block 36 increase the movable distance of the sliding column 37. The connecting plate 38 is fixedly connected to one end of the multiple groups of sliding columns 37 away from the slider 35, and the connecting plate 38 drives the two groups of sliding columns 37 to move synchronously. The support mechanism 3 also includes a push rod motor 39 installed on the top of the bottom plate 31. The output end of the push rod motor 39 is fixedly connected to the connecting plate 38. The push rod motor 39 is used to drive the connecting plate 38 to move after starting, thereby driving the top plate 32 to move. The end of the bottom plate 31 away from the bottom frame 11 is also fixedly connected with an auxiliary block 5, which is inclined to facilitate pushing and moving the placement rack 2 to the top of the top plate 32. The inclined surface of the auxiliary block 5 and the top of the top plate 32 are both provided with a slide groove corresponding to the moving wheel 21 to limit the movement of the placement rack 2.

[0034] Further, such as Figure 1 and Figure 3As shown, a pushing assembly 4 is installed on the supporting mechanism 3 to drive the placement rack 2 to enter the furnace body 1 from the top of the supporting mechanism 3. The pushing assembly 4 includes a first fixed plate 41, a second fixed plate 42, a limiting rod 43, a limiting sleeve 44, and a synchronous plate 45. Two groups of L-shaped first fixed plates 41 are fixedly connected to the top of the top plate 32 and one end extends into the interior of the furnace body 1, so as to facilitate pushing the placement rack 2 into the furnace body 1. Two groups of second fixed plates 42 are fixedly connected to the top of the top plate 32, and the positions of the first fixed plate 41 and the second fixed plate 42 are fixed. Two groups of limiting rods 43 are respectively fixedly connected between the first fixed plate 41 and the second fixed plate 42 relative to each other, and the position of the limiting rod 43 is fixed. Two groups of limiting sleeves 44 are respectively slidably connected to the limiting rod 43, and the limiting sleeve 44 moves along the length direction of the limiting rod 43. The synchronous plate 45 is fixedly connected between the two groups of limit sleeves 44, and the synchronous plate 45 drives the two groups of limit sleeves 44 to move synchronously, so that the synchronous plate 45 moves smoothly under the limiting action of the limit sleeves 44 and the limit rod 43. The pushing assembly 4 also includes a moving sleeve 46, a pushing rod 47, a mounting plate 48, and a clamping column 49. The moving sleeve 46 is arranged in the synchronous plate 45, and the moving sleeve 46 moves synchronously with the synchronous plate 45. The pushing rod 47 is rotatably connected in the moving sleeve 46, and the pushing rod 47 drives the moving sleeve 46 to move synchronously when moving, and the pushing rod 47 itself can rotate. A handle is installed at one end of the pushing rod 47 away from the furnace body 1, which is convenient for pushing the pushing rod 47. Two groups of mounting plates 48 are arranged on the side of the moving sleeve 46 close to the furnace body 1 and are fixedly installed on the outer ring of the pushing rod 47. The clamping column 49 is fixedly connected between the two groups of mounting plates 48, and the pushing rod 47 drives the mounting plate 48 and the clamping column 49 to move synchronously when rotating. A movable plate 22 is also installed at the bottom of the placement rack 2 away from the furnace body 1, and the movable plate 22 moves synchronously with the placement rack 2. A limiting groove 23 is provided on the movable plate 22, and the clamping column 49 is slidably connected to the limiting groove 23, so that after the clamping column 49 enters the limiting groove 23, the push rod 47 drives the installation plate 48 to move when moving, thereby pushing or pulling the placement rack 2 to move.

[0035] In this embodiment, first, in the initial state, Figure 1In this case, place the object on the placement rack 2, hold the handle and push the push rod 47 to move. The push rod 47 drives the mounting plate 48 and the clamping column 49 to move, and at the same time pushes the placement rack 2 to move in the slide groove through the moving plate 22, so that the placement rack 2 moves into the furnace body 1. At this time, the push rod 47 is rotated to make the clamping column 49 slide out of the limit groove 23. At this time, the mounting plate 48 no longer drives the moving plate 22 to move when moving. Then, the push rod motor 39 is started to contract, so that it drives the connecting plate 38 away from the furnace body 1, and at the same time drives the sliding column 37, the fixed block 36, the slider 35, and the support plate 34 to move synchronously, and the top plate 32 is away from the furnace body 1. At this time, multiple groups of support rods 33 deflect, and the top plate 32 moves downward synchronously. Since the height of the sliding column 37 and the connecting plate 38 is fixed, the fixed block 36 slides downward, and the support plate 34 slides downward until the bottom of the support plate 34 contacts the bottom plate 31. At this time, one side of the top plate 32 contacts the auxiliary block 5. At this time, the top plate 32 no longer hinders the opening and closing of the furnace door, which is convenient for closing the furnace door to perform thermal release on the object. After the thermal release is completed, open the furnace door, start the push rod motor 39 to raise the top plate 32 and reset it after approaching the furnace body 1, move the push rod 47 and rotate it, so that the clamping column 49 slides into the limit groove 23, and the moving push rod 47 can drive the placement rack 2 to move out of the furnace body 1, which is convenient for cooling the object. Finally, start the push rod motor 39 to shrink so that the top plate 32 is close to the auxiliary block 5, and the placement rack 2 can be slid out of the top plate 32, which is convenient for the coating to be removed.

[0036] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
