Description

Technical Field

[0001] This invention belongs to the field of conveying equipment technology, and in particular relates to a thermal insulation board conveying device. Background Technology

[0002] The structure of thermal insulation boards consists of two substrates with an insulation layer sandwiched between them. Compared to solid boards, they are thicker and lighter. Currently, thermal insulation board production equipment is highly automated, capable of completing processes such as compaction, cutting, and edge trimming online. Afterward, the boards are conveyed to the packaging area for stacking and packaging.

[0003] Equipment typically used for conveying sheet metal is generally suitable for transporting insulation boards, such as the equipment disclosed in Chinese patents CN202222633622.0, CN202220376461.9, and CN202011004106.0. These conveying devices all use multiple parallel conveyor rollers to transport the sheet metal, with each roller connected to a motor or connected in series by chains to provide power. This method results in high energy consumption, numerous rotating parts in the conveyor line, and high manufacturing and maintenance costs.

[0004] To facilitate the unloading or conveying of sheet metal, a traverse mechanism is typically installed at the end of the conveyor line, as disclosed in Chinese patents CN201710651093.8 and CN201720833654.1. This complicates the overall structure of the conveyor line. When the traverse mechanism is in operation, the conveyor line needs to pause or some of the conveyor rollers at the end need to stop to complete the traverse movement of the sheet metal. This necessitates the installation of numerous sensors and complex control programs, increasing the purchase and maintenance costs of the entire conveyor line. Furthermore, a malfunction in any part of the process can cause the entire conveyor line to stop, disrupting the production cycle.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

Detailed Implementation

[0035] See Figure 1 The present invention provides a thermal insulation board conveying device, including

[0036] Conveyor 1, combined with Figure 2 The conveyor table 1 has multiple air jet holes 12 arrayed on its surface; gas is continuously ejected from the air jet holes 12, and the substrate of the insulation board 200 is relatively smooth, so an air film is formed between the insulation board 200 and the conveyor table 1, so that the insulation board 200 is slightly suspended relative to the conveyor table 1, thereby greatly reducing the friction force, and the insulation board 200 can be moved along the surface of the conveyor table 1 with a small thrust.

[0037] Better still, along the conveying direction, the jet hole array on the conveyor table 1 includes multiple parallel rows of jet holes with equal spacing, and each row of jet holes has multiple jet holes 12 with equal spacing.

[0038] See Figure 3 In one embodiment, the conveyor table 1 includes a top plate 13, on which air jet holes 12 are provided; a side plate 14 is fixedly connected to both sides of the top plate 13, and the two side plates 14 are also fixedly connected to the same bottom plate 15; a support leg 11 is fixedly provided below the bottom plate 15.

[0039] The top plate 13, bottom plate 15, and side plate 14 together form an air intake space, with an end panel at each end of the air intake space, making the air intake space a closed space; an air intake hole 151 is opened on the bottom plate 15, and the air intake hole 151 is connected to the main air intake pipe 16, combined with Figure 4 One end of the main air intake pipe 16 is closed, and the other end is connected to the air intake fan 161;

[0040] Gas at a certain pressure is blown in by the air intake fan 161, so that the gas ejected from the jet nozzle 12 has sufficient pressure to form an air film. Those skilled in the art can select the specifications of the air intake fan 161 according to the specifications of the insulation board 200 being conveyed.

[0041] See Figure 8 As one embodiment, the conveyor table 1 includes a top plate 13, on which air jet holes 12 are provided; a side plate 14 is fixedly connected to both sides of the top plate 13, and a bottom plate 15 is fixedly connected to the bottom of each side plate 14.

[0042] Even better, each side plate 14 is connected to its corresponding bottom plate 15 by multiple reinforcing plates 17;

[0043] See Figure 9 The bottom of the top plate 13 is fixed with the same number of air distribution pipes 19 as the number of jet hole rows; each air distribution pipe 19 has a long strip opening, and the opening is connected to all the jet holes 12 in the corresponding jet hole row; each air distribution pipe 19 is connected to an air intake pipe 18, and each air intake pipe 18 is connected to the main air intake pipe 16.

[0044] The connection between the gas distribution pipe 19 and the top plate 13 in this invention is a sealed connection; it can be achieved by welding, preferably by resistance welding, which results in fast weld formation and good sealing. Fusion welding or brazing can also be used for the connection.

[0045] The gas is distributed through the gas distribution pipe 19, ensuring stable pressure of the gas ejected from the jet holes 12 in each jet hole row, and providing strong resistance to pressure fluctuations. During regular maintenance, only the leaking locations need to be repaired, or the damaged gas distribution pipe 19 needs to be replaced. Maintenance costs are low.

[0046] In this embodiment, the end panel can be omitted, and the two base plates 15 only need to meet the installation and fixation of the support legs 11; thus reducing the overall weight of the conveyor table 1, saving manufacturing materials, and reducing manufacturing costs.

[0047] Combination Figure 5 A drive assembly is installed on each of the two side plates 14; the drive assembly includes two end sprockets 21 rotatably mounted on the side plates 14, and a drive chain 2 is wound between the two end sprockets 21; a plurality of push rods 23 are installed on the drive chain 2; one end sprocket 21 of each drive assembly is connected to a drive motor.

[0048] The width of the conveying table 1 of the present invention is smaller than the width of the insulation board 200 being conveyed; the push rods 23 of the two side plates 14 abut against the ends of the insulation board 200, and with the transmission of the drive chain 2, push the insulation board 200 to move along the conveying table 1; since the air film between the insulation board 200 and the conveying table 1 greatly reduces the friction, the drive motor does not need to output a large power to complete the conveying of the insulation board 200, which significantly reduces the energy consumption of the conveying.

[0049] Those skilled in the art can set the length of the conveyor table 1 according to the actual length of the workshop and the required conveying distance. To avoid excessive sag in the middle part of the drive chain 2 during long-distance conveying, causing the push rod 23 to lose contact with the insulation plate 200.

[0050] Even better, 2-4 transition sprockets 22 are provided between the two end sprockets 21 of each drive component to divide the drive chain 2 into multiple segments of equal length, thereby reducing the amplitude of sag.

[0051] As a preferred option, see Figure 6 A push rod box 24 is fixedly connected to the drive chain 2. The push rod box 24 is open at both ends and has an open top. A push rod shaft 231 is fixed inside the push rod box 24. The push rod shaft 231 rotatably passes through the push rod 23. The lower end of the push rod 23 is connected to a stop plate 232. When the push rod 23 is in an upright state, the stop plate 232 abuts against the bottom outer end face of the push rod box 24.

[0052] When the insulation board 200 is delivered onto the conveyor table 1 with a certain initial velocity, it can slide along the conveyor table 1 on its own. Figure 7 When the insulation board 200 encounters the push rod 23 in front during sliding, the push rod 23 rotates forward and falls down to avoid obstructing the insulation board 200. During the return stroke of the drive chain 2, the push rod 23 returns to an upright state under the action of gravity, without affecting the pushing of the insulation board 200.

[0053] Even better, multiple vertical side guard rollers 3 are respectively provided on the two side plates 14 to prevent the insulation board 200 from slipping off the side. Each side guard roller 3 is rotatably sleeved with a roller shaft 31, and the lower end of the roller shaft 31 is fixed to a support plate 32, which is fixed to the side plate 14.

[0054] As one embodiment, the conveyor table 1 of the present invention includes a conveying section and an unloading section; the drive assembly and the side rollers 3 are both arranged within the length range of the conveying section;

[0055] See Figure 10 A side-pushing mechanism is provided on one side of the unloading section; combined with Figure 11 The side-pushing mechanism includes a reciprocating carriage 4, one side of which is connected to a side-pushing plate 41, and the other end is connected to a side-pushing cylinder 42.

[0056] The side-push cylinder 42 extends, and the side-push plate 41 pushes the insulation board 200 off the conveyor table 1. Those skilled in the art can install a receiving mechanism or receiving cart 300 with lifting function at the other end of the unloading section; after each insulation board 200 is received, it lowers by a distance slightly greater than the board thickness, allowing each insulation board 200 to slide down horizontally. Because the air film reduces friction, a large lateral thrust is not required. The side-push cylinder 42 of this invention is preferably a pneumatic cylinder, with rapid extension and retraction, enabling quick pushing down of the insulation board 200.

[0057] As a preferred embodiment, the reciprocating carriage 4 of the present invention is equipped with an auxiliary suction assembly 100; the auxiliary suction assembly 100 includes a fixing plate 51 fixed on the reciprocating carriage 4; a lifting cylinder 54 is installed on the fixing plate 51, and the telescopic part of the lifting cylinder 54 is connected to a lifting plate 52; at least two suction cup components 5 are fixed on the lifting plate 52.

[0058] The suction cup 5 extends to the middle of the conveyor table 1 and is connected to a negative pressure source. During unloading, the lifting cylinder 54 descends, causing the suction cup 5 to adhere to the surface of the insulation board 200. Then, the side push cylinder 42 actuates, pushing the insulation board 200 down. Due to the adhesion of the suction cup 5, the insulation board 200 is better kept horizontal during the pushing process.

[0059] Since the suction cup component 5 of this invention only needs to maintain the horizontal posture of the insulation board 200, a large suction force is not required. Depending on the specifications of the insulation board 200 being conveyed, a suction force of 10-20 kg per suction cup component 5 is sufficient to meet the requirements, and the power demand is not high.

[0060] Even better, multiple guide rods 53 that are movably connected to the lifting plate 51 are fixedly connected to the lifting plate 52, so that the lifting plate 52 can be raised and lowered smoothly.

[0061] The present invention can install a baffle on the conveyor table 1 to prevent the insulation board 200 from sliding down.

[0062] In summary, the present invention provides an insulation board conveying device, which uses air jet holes on the surface of the conveying table to continuously eject gas, forming an air film between the insulation board and the conveying table, thereby greatly reducing friction. The insulation board can be moved along the surface of the conveying table with a small thrust, significantly reducing conveying energy consumption.

[0063] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.
