DETAILED DESCRIPTION

[0038] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] like Figure 1~Figure 5 As shown, this embodiment provides an aluminum profile spray curing furnace, including a furnace body 1, and also including:

[0040] A transport device 2, cyclically rotatably disposed on the furnace body 1;

[0041] The clamping device is used to move and transport the aluminum profiles following the transport device 2 in the furnace body 1. The clamping device includes two clamping members 3. The two clamping members 3 are respectively supported and clamped on the upper and lower sides of the aluminum profile. The clamping members 3 include:

[0042] An inner support clamping portion 301, the end of which is slidably abutted against the inner wall of the aluminum profile;

[0043] The cross 302 is arranged on the inner support clamping portion 301 and is located outside the aluminum profile;

[0044] A connecting shaft 303, through which the cross 302 is rotatably connected to the transport device 2;

[0045] The limiting device 4 includes:

[0046] At least two limit plates 401 and at least two first limit members 402, a limit plate 401 and a first limit member 402 are relatively arranged at the upper and lower sides of the furnace body 1, and the limit plate 401 and an end face of the cross 302 on one of the upper and lower sides are slidably matched, the first limit member 402 is abutted against the side of the cross 302 on the other side, and the cross 302 rotates after abutting against the first limit member 402 when the cross 302 moves, and the limit plate 401 and the first limit member 402 on the same side are arranged in sequence along the transportation direction of the aluminum profile.

[0047] In this embodiment, the transport device 2 is a chain, rope, etc., which circulates inside and outside the furnace body 1 to drive the aluminum profile to move and solidify. In order to improve the solidification effect of the aluminum profile and enable multiple aluminum profiles to be efficiently solidified, the clamping device moves the aluminum profile vertically along the height direction. The end of the inner support clamping portion 301 slides against the inner wall of the aluminum profile, and the aluminum profile is fixed by abutting against the inner wall of the aluminum profile, so that the aluminum profile remains stably fixed in the vertical direction. The cross 302 and the connecting shaft 303 are used to connect the inner support clamping portion 301 and the transport device. When the aluminum profile moves, the limit plates 401 and the first limit members 402 located at the upper and lower ends of the aluminum profile simultaneously contact the crosses 302 on the upper and lower sides, so that the abutment portion 4022 between the inner support support portion and the inner wall of the aluminum profile changes;

[0048] Specifically, a plurality of limit plates 401 and first limit members 402 are arranged in the moving direction of the aluminum profile, and the first limit members 402 and the limit plates 401 are arranged opposite to each other up and down, and are arranged in groups in the moving direction of the aluminum profile; during the movement of the aluminum profile, taking the case where the first limit member 402 is arranged at the top and the corresponding limit plate 401 is arranged at the bottom as an example, the first limit member 402 located at the top abuts against the cross 302 at the top, so that the cross 302 rotates, and at the same time, the end face of the cross 302 located at the bottom abuts against the limit plate 401 at the bottom, and the limit plate 401 at the bottom shapes the cross 302 at the bottom. The limiter 302 is formed to limit the rotation of the lower cross 302, so that only the upper cross 302 can rotate, which drives the upper inner support clamping part 301 to rotate, thereby realizing the change of the fixed position while keeping the aluminum profile stable; further, after the aluminum profile moves, the limit plate 401 is set at the top and the first limit member 402 is set at the bottom. This process refers to the above process to realize the rotation of the lower inner support clamping part 301, and further realize the change of the lower fixed position. During the movement of the aluminum profile, a corresponding number of limit devices 4 can be set according to actual conditions, and at least two groups are required to realize the change of the upper and lower fixed positions.

[0049] Through the above scheme, the fixed position of the aluminum profile changes during the mobile solidification process, thereby effectively improving the solidification effect of the aluminum profile and reducing the influence of the clamping device on the solidification effect of the clamping part.

[0050] Furthermore, the transport device 2 is a chain transmission component, and the transport device 2 is arranged on both the upper and lower sides of the furnace body 1, and also includes: a second limit member 403, which is arranged on the upper or lower side of the furnace body 1. When the cross 302 moves and abuts against the second limit member 403, the cross 302 and the aluminum profile body on the upper and lower sides rotate synchronously.

[0051] In this embodiment, the conveying device is a chain transmission member. Compared with the belt transmission, there is no elastic sliding, and the accurate average transmission ratio can be maintained, and the transmission efficiency is high. The chain does not require a large tensioning force, so the load on the shaft and the bearing is small. It will not slip, the transmission is reliable, the overload capacity is strong, and it can work well under low speed and heavy load. The second limiter 403 is a convex block, which is set at the same height as the first limiter 402 and the limiter plate 401. A second limiter 403 is set on the upper side or the lower side of the aluminum profile body, or a second limiter 403 is set on the upper and lower sides.

[0052] Specifically, taking the case where a second limit piece 403 is provided on the upper side (or lower side) of the aluminum profile, during the movement of the aluminum profile, after the cross 302 abuts against the second limit piece 403, the cross 302 rotates, driving the connected inner support clamping part 301 to rotate. After the inner support clamping part 301 rotates, it drives the aluminum profile to rotate. Further, the aluminum profile drives the inner support clamping part 301 on the lower side to rotate, thereby achieving synchronous rotation.

[0053] During the curing process, the furnace body 1 is relatively large and the heating zone 8 is usually located on one side. During the heating process, the temperature at different positions of the furnace body 1 may be different. Therefore, the second limit member 403 is used to drive the overall rotation of the aluminum profile, so that the outer side surface of the aluminum profile is adjusted in position, thereby improving the curing quality.

[0054] Furthermore, the first limiting member 402 has a mounting portion 4021 and an abutting portion 4022, wherein the abutting portion 4022 is arranged on one side of the mounting portion 4021, the mounting portion 4021 is arranged on the inner wall of the furnace body 1, the abutting portion 4022 abuts against the side of the cross 302, and the four ends of the cross 302 all have chamfered structures.

[0055] In this embodiment, the mounting portion 4021 of the first limiting member 402 is arranged on the inner wall of the furnace body 1, and the abutting portion 4022 abuts against the side of the cross 302, so that the cross 302 rotates more smoothly. The four ends of the cross 302 are chamfered structures to improve the abutting effect.

[0056] Furthermore, the inner support clamping portion 301 includes: a main body tube 3011, the middle part of the side wall of the main body tube 3011 is connected to the axis of the cross 302; an abutment rod 3012, which has two, and the two abutment rods 3012 are slidably connected to both sides of the main body tube 3011; an elastic member 3013, which has two, is arranged in the main body tube 3011, and respectively connects the two abutment rods 3012 and the main body tube 3011, and is used to provide pressure for the abutment rod 3012 to abut against the inner wall of the aluminum profile.

[0057] In this embodiment, the interior of the main tube 3011 is a partially hollow structure, and the middle part of the side wall is connected to the axis of the cross 302. After the cross 302 rotates, it drives the main tube 3011 to rotate around the connection with the cross 302. The abutment rod 3012 is used to abut against the inner wall of the aluminum profile. The elastic member 3013 is arranged in the main tube 3011 to provide pressure for the abutment rod 3012 to abut against the inner wall of the aluminum profile.

[0058] During the processing and curing of the aluminum profile, the inner diameter of the aluminum profile may be different. The arrangement of the elastic member 3013 and the abutment member can better adapt to aluminum profiles with different inner diameters, thereby improving adaptability.

[0059] Furthermore, there are multiple clamping devices, and the multiple clamping devices are arranged in an array along the transportation direction of the aluminum profile.

[0060] In this embodiment, there are multiple clamping devices, and multiple clamping devices can transport multiple aluminum profiles at the same time. During the transportation process, the fixed position of the inner support clamping part 301 can be changed through the limiting device 4, thereby improving work efficiency.

[0061] Furthermore, the four end faces of the cross 302 are all planes.

[0062] In this embodiment, after the cross 302 enters the limiting plate 401, the limiting plate 401 needs to fix the cross 302 so that the cross 302 on the other side can be rotated while the cross 302 located on the inner side of the limiting plate 401 is fixed and stable. Therefore, the four end faces of the cross 302 are designed to be planes. After the end faces abut against the side of the limiting plate 401, the fixing effect can be improved.

[0063] Furthermore, the furnace body 1 has a feeding zone 5 , a discharging zone 6 and a curing zone 7 . The curing zone 7 is located between the feeding zone 5 and the discharging zone 6 . The feeding zone 5 and the discharging zone 6 are higher than the curing zone 7 .

[0064] In this embodiment, the furnace body 1 is a high-temperature environment and needs to maintain a high temperature. In order to save energy and improve the insulation effect, the feeding area 5 and the discharging area 6 are designed to be higher than the curing area 7 to form a certain slope, thereby improving the insulation effect of the curing area 7 located in the middle.

[0065] Furthermore, the transport device 2 passes through the feeding area 5, the curing area 7 and the discharging area 6 in sequence during transport.

[0066] In this embodiment, the transport route of the transport device 2 is the same as the arrangement position of the feeding area 5, the discharging area 6 and the curing area 7 in the furnace body 1, driving the aluminum profile to be cured to enter the feeding area 5, the curing area 7 and the discharging area 6 in sequence.

[0067] Furthermore, the furnace body 1 also has a heating zone 8 , which is located below the curing zone 7 , and the curing zone 7 is connected to the heating zone 8 through a plurality of heating ports 9 .

[0068] In this embodiment, in order to improve the temperature uniformity in the curing zone 7 , a plurality of heating ports 9 are designed, and the plurality of heating ports 9 are connected to the heating zone 8 , thereby effectively improving the temperature uniformity in the curing zone 7 .

[0069] Furthermore, it also includes: a collecting area 10, located at the upper end of the furnace body 1; a collecting port 11, arranged on the furnace body 1, and the feeding area 5 and the discharging area 6 are both connected to the collecting area 10 through the collecting port 11; a filtering device 12, arranged in the collecting area 10, the filtering device 12 has an air inlet and an exhaust port, and the exhaust port is connected to the outside of the collecting area 10; an exhaust pump 13, having an exhaust end and an exhaust end, the exhaust end is connected to the inside of the collecting area 10, and the exhaust end is connected to the air inlet.

[0070] In this embodiment, the collection area 10 is used to collect the exhaust gas after heating in the furnace body 1. The collection port 11 is located above the heating area 8, so that the hot air enters the collection area 10 after the aluminum profile is heated. The filter device 12 can collect and filter the exhaust gas, and the vacuum pump 13 is used to extract the exhaust gas and allow it to enter the filter device 12.

[0071] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
