DETAILED DESCRIPTION

[0033] In order to better understand the purpose, structure and function of the present invention, the present invention is clearly and completely described below in conjunction with the accompanying drawings.

[0034] like Figure 1-Figure 4 The duct prefabrication processing device shown in the figure comprises: a conveyor 1 and a pressing mechanism, a positioning mechanism, a cutting mechanism and a cooling mechanism 7 arranged on the upper part of the conveyor 1. The pressing mechanism, the positioning mechanism, the cooling mechanism 7, the cutting mechanism and another pressing mechanism are arranged in sequence along the conveying direction. The upper part of the conveyor 1 is used to convey the duct prefabricated parts. In this embodiment, the conveyor 1 is a roller conveyor 1, comprising two frames 1-1, a plurality of conveying rollers 1-3 arranged between the two frames 1-1, and a motor 1-4 coaxially connected to any of the conveying rollers 1-3. The motor 1-4 is connected to the conveying roller 1-3 through a coupling. The motor 1-4 is installed on the frame 1-1 through a motor seat. When the motor 1-4 is started, it drives the conveying roller 1-3 connected thereto to rotate, thereby driving the duct prefabricated parts to move in the conveying direction to achieve the purpose of conveying. In order to increase the stability of the conveyor 1, a plurality of legs 1-5 are provided at the bottom of the frame 1-1, and the legs 1-5 at the bottom of the two frames 1-1 are symmetrically arranged, and the upper parts are connected to the frames 1-1 by bolts.

[0035] The positioning mechanism is adapted to the width of the air duct prefabricated part to prevent the air duct prefabricated part from shaking left and right during the conveying process. Figure 1 and Figure 2 As shown, the locking mechanism includes a locking assembly 6 symmetrically arranged on the two frames 1-1; each of the locking assembly 6 includes a spring 6-1 and a top plate 6-2, the spring 6-1 is horizontally arranged, one end of which is connected to the frame 1-1, and the other end is connected to one side of the top plate 6-2, the other side of the top plate 6-2 is used to abut against the air duct prefabricated part, and the horizontal plane where the bottom of the top plate 6-2 is located is tangent to the upper part of the conveying roller 1-3, and does not affect the normal operation of the conveying roller 1-3 when cooperating with the air duct prefabricated part, and can adapt to air duct prefabricated parts of various thicknesses; each of the frames 1-1 is provided with two "∟"-shaped limit plates 1-2, the two limit plates 1-2 are symmetrically arranged, and slide with the top plate 6-2. In order to increase stability, two springs 6-1 are arranged between each top plate 6-2 and the frame 1-1. Since the spring 6-1 is retractable, the two symmetrical top plates 6-2 can adapt to air duct prefabricated parts of different widths, and the limit plate 1-2 slides with the top plate 6-2, that is, the limit plate 1-2 can limit the movement of the top plate 6-2. Specifically, the bottom of the limit plate 1-2 can prevent the top plate 6-2 from moving downward, and the two sides prevent the top plate 6-2 from moving in the conveying direction or in the opposite direction.

[0036] The cutting mechanism is used to cut the air duct prefabricated parts; Figure 3 As shown, the cutting mechanism includes an adjustment component 2, two lifting components 3 connected to the adjustment component 2, and two cutters 4 respectively connected to the two lifting components 3. The adjustment component 2 is used to adjust the distance between the two cutters 4 and the two frames 1-1 on the left and right sides of the conveyor 1, and the lifting component 3 is used to drive the cutters 4 to move up and down. The position of the cutter 4 is adjusted by the adjustment component 2 to adjust the cutter 4 to the position to be cut, and the cutter 4 is driven downward by the lifting component 3 to cut the air duct prefabricated part.

[0037] Specifically, the adjustment component 2 includes two pairs of mounting plates 2-1, a double-headed screw 2-2 and a guide rod 2-3, and the surface of the guide rod 2-3 is smooth; the two pairs of mounting plates 2-1 are respectively installed on the upper part of the two frames 1-1, the guide rod 2-3 is arranged between one pair of the mounting plates 2-1, and the double-headed screw 2-2 is rotatably connected between the other pair of mounting plates 2-1 through bearings, one end of the double-headed screw 2-2 passes through the mounting plate 2-1 and is coaxially connected to the motor 2-4; the guide rod 2-3 and the double-headed screw 2-2 both pass through the two ends of the lifting component 3, and are respectively slidably connected and threadedly connected to the lifting component 3. When the motor 2-4 is working, it can drive the double-headed screw 2-2 to rotate. Under the guiding effect of the guide rod 2-3 and the threaded connection between the double-headed screw 2-2 and the lifting component 3, the lifting component 3 drives the cutter 4 to move along the axial direction of the guide rod 2-3. Since the screw is a double-headed screw 2-2, when the motor 2-4 is working, the two lifting components 3 drive the two lifting components 3 and the cutter 4 to move closer to or away from each other, thereby symmetrically adjusting the positions of the two cutters 4 so that the positions of the cutters 4 are adapted to the positions of the air duct prefabricated parts to be cut.

[0038] The lifting assembly 3 includes a cylinder 2, which is connected to the adjustment assembly 2, and the output shaft of the cylinder 2 is connected to the upper end of the cutter 4. For the convenience of connection, both ends of the cylinder 2 are welded or bolted to the connecting blocks, one of which is provided with a threaded hole matching the double-headed screw 2-2, and the other is provided with a through hole passing through the guide rod 2-3, so that the motor 1 2-4 can drive the cylinder 2 and the cutter 4 to move closer to or away from each other.

[0039] Since friction generates heat during the cutting process, a cooling mechanism 7 is provided in the device to avoid accidents. In this embodiment, the cooling mechanism 7 includes a water tank 7-1, a water outlet pipe 7-2, and a limit block 7-3 connected to the cutting mechanism; the water tank 7-1 is located at the upper part of the frame 1-1, and its outlet is connected to the water outlet pipe 7-2. The water outlet pipe 7-2 is inserted into the limit block 7-3, and its free end points to the cutter 4. Specifically, the end of the limit block 7-3 is connected to the connecting block, and a channel for passing the water outlet pipe 7-2 is provided inside the limit block 7-3, and an outlet connected to the channel is provided at the bottom. The water outlet pipe 7-2 passes through the channel and then passes out from the outlet to the cutter 4; since the limit block 7-3 is connected to the cylinder 2, when the cylinder 2 and the cutter 4 move, the free end of the water outlet pipe 7-2 also moves accordingly, always pointing to the direction of the cutter 4. Of course, the water outlet pipe 7-2 is also provided with a valve and a power pump to provide power and control the flow rate of the water outlet pipe 7-2.

[0040] In order to prevent the duct prefabricated parts away from the cutting mechanism from deviating upward during the cutting process, resulting in errors in the shearing size, the pressing mechanism is provided to apply downward pressure to the duct prefabricated parts. Two groups of the pressing mechanism are provided, which are respectively located at the beginning and end of the conveying direction of the conveyor 1.

[0041] like Figure 4 As shown, each group of the pressing mechanism includes two pressing assemblies 5, and the two pressing assemblies 5 are respectively arranged on the upper part of the two racks 1-1; each pressing assembly 5 includes a "┐"-shaped mounting frame 5-1, a cylinder 1 5-2 and a pressing plate 5-3; the bottom of the vertical part 5-11 of the mounting frame 5-1 is connected to the upper part of the rack 1-1, the bottom of the horizontal part 5-12 is connected to the cylinder 1 5-2, and the output shaft of the cylinder 1 5-2 is downwardly connected to the pressing plate 5-3. After the air duct prefabricated part is placed on the conveyor 1, the cylinder 1 5-2 is started to drive the pressing plate 5-3 to move downward, and the pressing plates 5-3 of the two racks 1-1 apply pressure to the left and right sides of the air duct prefabricated part to limit the height direction of the air duct prefabricated part.

[0042] A method for using a duct prefabrication device, characterized in that it comprises the following steps:

[0043] Step 1: Place the air duct prefabricated part on the upper part of the conveyor 1; after placement, turn on the motor 2 1-4 to transfer the end of the air duct prefabricated part to the position of the locking mechanism.

[0044] Step 2: Adjust the locking mechanism so that the two ends of the air duct prefabricated part contact the end of the locking mechanism to limit the left and right directions of the air duct prefabricated part; specifically, press the top plate 6-2 toward one side of the frame 1-1, and the top plate 6-2 slides along the end of the limiting plate 1-2 so that the air duct prefabricated part is located between the two top plates 6-2; release the top plate 6-2, and under the action of the restoring force of the spring 6-1, the end of the top plate 6-2 contacts the air duct prefabricated part to limit the left and right directions of the air duct prefabricated part.

[0045] Step three: adjust the pressing mechanism so that the upper part of the air duct prefabricated part contacts the lower part of the pressing mechanism, and limit the upper and lower directions of the air duct prefabricated part; since there is already an air duct prefabricated part between the head end of the conveyor 1 and the clamping mechanism, first adjust the pressing mechanism at the head end, start the cylinder 1 5-2 to drive the pressing plate 5-3 to move downward, so that the bottom of the pressing plate 5-3 contacts the upper part of the air duct prefabricated part, and limit the upper part of the air duct prefabricated part; adjust the position of the end pressing mechanism according to the position of the pressing plate 5-3 in the pressing mechanism at the head end, so that the position heights of the pressing plates 5-3 on both sides are consistent.

[0046] Step 4: Adjust the lifting assembly 3 and the adjusting assembly 2 so that the cutter 4 is located at the position to be cut; first start the motor 1 2-4 to drive the stud to rotate, thereby driving the cutter 4 to the position to be cut, and then start the cylinder 2 to drive the cutter 4 to move downward, so that the horizontal plane where the bottom of the cutter 4 is located is tangent to the upper part of the conveying roller 1-3.

[0047] Step 5: Start the conveyor 1 and the cooling mechanism 7 to drive the air duct prefabricated part to be transported. During the transport process, the cutter 4 cuts the air duct prefabricated part, and the cooling mechanism 7 cools down the cutting position.
