Description

Technical Field

[0001] The utility model relates to the field of mechanical transmission, in particular to a conveying device. Background Art

[0002] The tunnel furnace is a tunnel-type mechanical equipment that bakes products through heat conduction, convection and radiation. The tunnel furnace body is generally very long, and the baking chamber is a narrow tunnel with a continuously running conveyor line in the tunnel. The product is placed on the tooling, and the tooling generates relative movement between the conveyor chain plate, steel belt or mesh belt and the electric heating element or direct combustion rod. Thus, the work of uniform baking and conveying is completed. In order to fully bake the product in the tunnel furnace, the running speed of the conveyor line is usually slowed down, but this will result in a small amount of loading and a long production cycle.

[0031] like Figure 2 The first conveyor line 1, the second conveyor line 2 and the third conveyor line 3 form a continuous "S"-shaped conveying device through the first material picking and transferring mechanism 8 and the second material picking and transferring mechanism 9. The structure is compact. Under the condition that the length and width of the tunnel furnace are determined, the flow path of the product in the tunnel furnace is extended to the maximum extent, so that the product has sufficient baking time and is baked evenly.

[0032] like Figure 3Any one of the first conveyor line 1, the second conveyor line 2, the third conveyor line 3 and the fourth conveyor line 4 includes a conveyor chain assembly 10, an auxiliary wheel assembly and a guide component; the conveyor chain assembly 10 includes a driving sprocket, a driven sprocket, a chain and a motor 11, the chain is wound around the driving sprocket and the driven sprocket, the motor 11 drives the driving sprocket to rotate, and a plurality of positioning blocks 12 are installed on the chain at equal intervals. The conveyor chain assembly 10 also includes a plurality of push blocks 13, the push blocks 13 are detachably plugged into the positioning blocks 12, and the plurality of push blocks 13 are distributed at equal intervals along the chain; the auxiliary wheel assembly includes two rows of rollers 15, and the conveyor chain assembly 10 is located between the two rows of rollers 15; the guide component includes two guide bars 14 parallel to the conveyor chain assembly 10, the two guide bars 14 are respectively located on the side of the two rows of rollers 15 facing away from the conveyor chain assembly 10, and the top surface of the guide bar 14 is higher than the top of the roller 15. The product is placed between two push blocks 13, and two guide bars 14 are used to limit the two sides of the product. The guide bars 14 and the push blocks 13 limit the four sides of the product to prevent the product from moving on the conveyor line. Photoelectric sensors 16 are installed at both ends of the conveyor chain assembly 10. Proximity switches 17 are installed at both ends of the chain, which can sense the push blocks 13 installed at equal distances on the chain.

Specifically, a groove 18 is provided on the top surface of the positioning block 12, and a positioning column that plugs and matches the groove 18 on the positioning block 12 is provided at the bottom of the push block 13. In other embodiments, the groove 18 can also be provided at the bottom of the push block 13, and the positioning column can be provided on the top surface of the positioning block 12. Preferably, the positioning block 12 and the push block 13 are both in the shape of long strips, and the length direction of both is perpendicular to the chain transmission direction. The top surface of the positioning block 12 is provided with at least two grooves 18 along the length direction, and correspondingly, at least two positioning columns are provided at the bottom of the push block 13. The long strip-shaped push block 13 is conducive to increasing the contact surface between the push block 13 and the product or tooling 20, and avoiding the displacement of the product or tooling 20. Chamfers 19 are provided on the top of both sides of the push block 13 in the width direction, which is conducive to placing the tooling 20 or the product between the two push blocks 13.

The motor 11 drives the chain to move, and the tooling 20 is placed between the push blocks 13 installed at equal distances on the chain. When the chain moves, the push blocks 13 push the tooling 20 to slide forward on the two rows of rollers 15.

The feed transition mechanism 5 is a belt conveying mechanism, specifically including a motor 11, a plurality of rollers 15 and a belt 21 wound around the rollers 15. The motor 11 drives the rollers 15 to rotate, thereby driving the belt 21 to run. The belt 21 conveyor line can be replaced by a linear module, a cylinder, a conveyor chain and other mechanisms. The feed transition mechanism 5 conveys the tooling 20 loaded with products to the feed transfer mechanism 6.

[0036] like Figure 5 The feeding and moving mechanism 6 includes a first cylinder 61 and two rows of rollers 15. The two rows of rollers 15 are mounted on the slide of the first cylinder 61. The axial direction of the rollers 15 is perpendicular to the reciprocating direction of the slide. Baffles 62 are installed on both sides of the first cylinder 61 to prevent the tooling 20 from falling. The first cylinder 61 can be replaced by a linear module, a conveyor chain and other mechanisms. The first cylinder 61 transports the tooling 20 with products placed on the two rows of rollers 15 to the bottom of the feeding and pushing mechanism 7.

[0037] The running direction of the feeding pushing mechanism 7 is the same as that of the feeding transition mechanism 5, and both are perpendicular to the running direction of the feeding moving mechanism 6. Figure 5 The feeding and pushing mechanism 7 includes two docking rails 71 arranged side by side at intervals, a second cylinder 72 located above the two docking rails 71, and a pushing block 73 connected to the slide of the second cylinder 72 and extending downward. The second cylinder 72 is straddled on the first conveyor line 1 and the feeding and moving mechanism 6. The second cylinder 72 drives the pushing block 73 to reciprocate along the extension direction of the docking rails 71. The two docking rails 71 are docked with the first conveyor line 1 and with the two rows of rollers 15 moved to the bottom of the second cylinder 72. The pushing block 73 is used to push the tooling 20 placed on the two rows of rollers 15 to the first conveyor line 1 via the two docking rails 71.

[0038] The first material picking and moving mechanism 8 and the second material picking and moving mechanism 9 have the same structure. Figure 5The first material picking and moving mechanism 8 includes a column, a fifth cylinder 81 installed horizontally on the column, a third cylinder 82 connected to the slide of the fifth cylinder 81 and vertically arranged, and a fourth cylinder 83 connected to the end of the push rod of the third cylinder 82. A clamping block 84 is respectively connected to the cylinder body and the push rod of the fourth cylinder 83. The fourth cylinder 83 drives the two clamping blocks 84 to move closer to or away from each other in the horizontal plane, thereby picking up or releasing the tooling 20.
