DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figure 1-7 As shown, a curing furnace for glass wool board production includes a conveying frame 1, a curing furnace 2 arranged on the conveying frame 1, and limiting slide grooves 3 opened on both sides of the table of the conveying frame 1.

[0032] The protective assembly 4 is also provided on the limiting slide groove 3, and the protective assembly 4 includes a sliding seat 41 slidably provided inside the limiting slide groove 3, a threaded shaft 42 and a limiting slide rod 43 provided at one end of the sliding seat 41, the threaded shaft 42 and the sliding seat 41 are rotatably connected, a lifting sleeve 44 sleeved on the threaded shaft 42, a traction sleeve rod 45 provided on the outside of the lifting sleeve 44, and the traction sleeve rod 45 and the limiting slide rod 43 are slidably connected, a supporting slide rod 46 provided on the outside of the lifting sleeve 44, and two groups of right-angle plates 47 slidably provided on the supporting slide rod 46, The windshield 48 arranged on the opposite side of the right-angle plate 47 is rotated, and the bidirectional screw 49 arranged on the right-angle plate 47 away from one end of the support slide rod 46 is rotated. A transparent visual window is arranged on one side of the curing furnace 2. The front and rear ends of the curing furnace 2 are provided with inlet and outlet ports. The limiting slide groove 3 is located inside the curing furnace 2, and the shape of the limiting slide groove 3 is T-shaped. The highest end of the protective component 4 is lower than the inlet and outlet ports of the curing furnace 2. The edge corners of the glass wool board can be covered by the right-angle plate 47, thereby reducing the wind volume at the edge corners of the glass wool board, so that the glass wool board The temperature at the edge corners is reduced to avoid the phenomenon of charring and burning the edges due to excessive temperature. When heat curing glass wool boards of different specifications, the staff can pull the protective component 4 out of the curing furnace 2, and drive the lifting sleeve 44 to move up and down by rotating the threaded shaft 42, so as to change the height of the right-angle plate 47, so as to form a good coverage for glass wool boards of different thicknesses. The lifting sleeve 44 is connected to the limiting slide rod 43 through the traction sleeve rod 45, so that the lifting sleeve 44 can only move in the vertical direction and cannot rotate with the threaded shaft 42. To ensure the stability of the right-angle plate 47 during movement, one end of the right-angle plate 47 is slidably mounted on the supporting slide rod 46, and the other end is threadedly connected to the bidirectional screw rod 49. The supporting slide rod 46 forms a limit for the right-angle plate 47, so that when the staff rotates the bidirectional screw rod 49 in different directions, the right-angle plates 47 can be driven to move closer or farther away from each other, thereby covering glass wool boards of different widths. In addition, the highest end of the protective component 4 is lower than the inlet and outlet of the curing furnace 2, which is convenient for the staff to pull the protective component 4 out of the curing furnace 2 to adjust the upper parts thereof.

[0033] In the present embodiment, specifically, a handle 410 is provided in the center of the bidirectional screw rod 49, a fixed connection is formed between the wind shield plate 48 and the right angle plate 47 by a pin shaft 411, a follower gear 412 is provided at one end of the pin shaft 411, a limiting groove 413 is provided at one end of the right angle plate 47 close to the follower gear 412, and a limiting piece 414 for fixing the follower gear 412 is provided in the internal engagement of the limiting groove 413. During curing, the hot air flow diffuses from the center of the glass wool board to both sides, and the staff can adjust the air intake of the space formed by the edge corners of the right angle plate 47 and the glass wool board by adjusting the angle of the wind shield plate 48, so as to achieve the control of the ambient temperature at the edge corners of the glass wool board. The degree of control is as follows: specifically, when it is necessary to lower the ambient temperature at the edge corners of the glass wool board, the staff can pull the limit piece 414 to one side. The limit piece 414 is provided with a conical head, which can be used to engage the follower gear 412, thereby preventing the pin shaft 411 from rotating at will, thereby ensuring the stability of the wind shield 48. After pulling the limit piece 414, the fixation of the follower gear 412 is released. At this time, the wind shield 48 can be flipped downward by a certain angle, so that the cross-sectional area of ​​the space formed by the right-angle plate 47 and the edge corners of the glass wool board where hot air enters is reduced, thereby lowering the temperature. When it is necessary to increase the ambient temperature at the edge corners of the glass wool board, the staff can flip the wind shield 48 upward.

[0034] In the present embodiment, specifically, an interlayer cavity 415 is provided inside the right-angle plate 47, and a multi-directional screw rod 416 is provided inside the rotating frame of the interlayer cavity 415. A through hole 417 communicating with the interlayer cavity 415 is provided through the top end surface of the right-angle plate 47, and a plurality of groups of sealing strips 418 sleeved on the multi-directional screw rod 416 are provided inside the interlayer cavity 415, and the sum of the widths of the two through holes 417 spliced ​​together is equal to the diameter of the sealing strip 418. A positioning groove 419 is provided at the bottom of the sliding seat 41, and the through hole 417 provided on the right-angle plate 47 is used to discharge the hot air in the space formed by the edge corners of the right-angle plate 47 and the glass wool board to avoid excessively high ambient temperature. When the heating temperature at the edge corners of the glass wool board needs to be adjusted, the staff can also adjust the temperature by changing the straight The temperature is controlled by the air circulation cross-sectional area of ​​the through hole 418 opened on the corner plate 47, and the flow rate of hot air at the edge corners of the glass wool board is controlled by changing the air circulation cross-sectional area of ​​the through hole 417, so as to achieve the purpose of temperature control. Specifically, when the temperature at the edge corners of the glass wool board needs to be increased, the staff rotates the multi-directional screw 416 to make the sealing strips 418 in groups of two approach each other. The sealing strips 418 can block the through hole 417 in the process of approaching, thereby achieving the purpose of changing the air circulation cross-sectional area of ​​the through hole 417. The interlayer cavity 415 opened can limit the movement of the sealing strip 418. When the multi-directional screw 416 drives the sealing strip 418, the sealing strip 418 is not easy to deflect, thereby ensuring the stability of the sealing strip 418 during movement.

[0035] In the present embodiment, specifically, the inner top of the curing furnace 2 is provided with a blower 5 and a heating box 6 for heating the glass wool board, an air outlet hood 7 is set up inside the curing furnace 2, and the air outlet hood 7 is connected to the output end of the heating box 6 through a conduit, a hanging plate 8 is provided on one side of the interior of the curing furnace 2, an exhaust fan 9 is provided on the hanging plate 8, an air inlet pipe 10 is provided on the top of the curing furnace 2, a circulation pipe 11 is provided on the air inlet pipe 10, the input end of the circulation pipe 11 is connected to the curing furnace 2 and is located on a side close to the exhaust fan 9, a sealing cover 12 is provided on the top of the air inlet pipe 10, the blower 5 can convey the outside air to the inside of the curing furnace 2 through the air inlet pipe 10, and the input air can be heated by the heating box 6, thereby achieving For the purpose of thermal curing of the glass wool board, the exhaust fan 9 arranged on the curing furnace 2 can discharge the gas inside the curing furnace 2, so as to avoid overheating inside the device and ensure the temperature of the glass wool board when curing. One end of the exhaust gas delivery pipeline is connected to the air inlet pipe 10, so a part of the hot air will re-enter the heating box 6 during exhaust. Thus, while the device can stably maintain the internal temperature, the heat waste is greatly reduced. When the device needs to be heated up quickly, the staff can seal the air inlet pipe 10 through the sealing cover 12, so that the air inlet pipe 10 directly draws negative pressure air from the inside of the device, which further improves the heating speed of the device and reduces energy loss.

[0036] In the present embodiment, specifically, a receiving groove 13 is provided on the bottom wall of the limiting slide groove 3, a spring 14 is arranged inside the receiving groove 13, and a clamping strip 15 matching the positioning groove 419 is arranged on the top of the spring 14. When the staff pulls the protective component 4 outward, the sliding seat 41 squeezes the clamping strip 15, the spring 14 is deformed and compressed, and the clamping strip 15 is recovered to the inside of the receiving groove 13. At this time, the clamping strip 15 is released from the fixing of the sliding seat 41, and the sliding seat 41 can slide freely. When resetting the protective component 4, the protective component 4 can be pushed into the curing furnace 2. At this time, the clamping strip 15 is automatically inserted into the positioning groove 419 arranged on the sliding seat 41 under the elastic support of the spring 14, thereby limiting and fixing the protective component 4, thereby ensuring the stability of the protective component 4 during use.
