Description

Technical Field

[0001] The invention relates to the technical field of aluminum profile conveying, and in particular to a discharging and conveying device for aluminum profiles after extrusion. Background Art

[0002] During the extrusion process, aluminum profiles will generate a lot of heat due to the high pressure and high temperature. If this heat is not dissipated in time, it will affect the quality and performance of the aluminum profiles. Therefore, the extruded aluminum profiles need to be cooled to ensure their shape stability and performance improvement. The cooling process can not only improve the mechanical and physical properties of the material, but also help eliminate internal stress and prevent deformation and cracks. Common cooling methods include forced cooling with coolants (such as water or oily coolants), or air cooling, water mist cooling, etc., and it is convenient to perform surface processing on aluminum profiles after cooling.

[0003] At present, aluminum profiles are generally transported to cooling beds for centralized cooling through transportation devices after extrusion. However, the transportation process takes a certain amount of time, which may cause deformation and cracking of the aluminum profiles during transportation. After cooling on the cooling bed, the aluminum profiles need to be manually transported and collected. However, the surface of the aluminum profiles at this time has not been processed, and some burrs may remain on the surface and in the grooves of the aluminum profiles. As a result, some burrs remaining in the production process may injure the hands of the staff during transportation. In particular, aluminum profiles generally have grooves. Sometimes, in order to facilitate application, fingers are inserted into the grooves for transportation, which poses certain safety hazards. Summary of the invention

A circulating cooling mechanism is provided between the coolant tank 2, the U-shaped frame 3, the first cooling mechanism 5 and the second cooling mechanism 6. The circulating cooling mechanism is used to save cooling resources and reduce cooling costs;

[0047] The side grinding mechanism 4 is arranged between the first cooling mechanism 5 and the second cooling mechanism 6. The side grinding mechanism 4 is detachably connected to the bracket 1 and is distributed on both sides of the top of the bracket 1. The burrs on both sides of the aluminum profile body 7 are removed by friction between the side grinding mechanism 4 and the aluminum profile body 7.

[0048] The first cooling mechanism 5 includes a first limit block 51, which is fixedly connected to the U-shaped frame 3. A first through slot for accommodating the aluminum profile body 7 is provided on the inner side of the first limit block 51. Side plates 53 are fixedly connected to the inner walls on both sides of the through slot. An upper shower plate 52 is fixedly connected to the inner wall on the top side of the through slot. Spray holes 54 communicating with the circulating cooling mechanism are provided on the side plates 53 and the upper shower plate 52. The surface of the aluminum profile body 7 is cooled by the spray holes 54. The surfaces of the side plates 53 and the upper shower plate 52 are provided with frosted particles, which facilitate the removal of burrs from the aluminum profile body 7.

[0049] The second cooling mechanism 6 includes a second limit block 69, and the second limit block 69 is provided with a second through groove. The upper pressure plate 63 and the lower support plate 65 are detachably connected at the corners of the inner wall of the second through groove. According to the shape and size of the aluminum profile body 7, a suitable upper pressure plate 63 and a lower support plate 65 are selected, and the burrs in the groove are removed by the adapted first sandpaper rod 64 and second sandpaper rod 66. The upper pressure plate 63 and the lower support plate 65 are respectively fixedly connected with the first sandpaper rod 64 and the second sandpaper rod 66 that fit the groove of the aluminum profile body 7. The inner wall of the second through groove is detachably connected with a transfer pipe 61 that communicates with the circulating cooling mechanism. The outer wall of the transfer pipe 61 is fixedly connected to the extrusion plate 62. The outer wall of the extrusion plate 62 is fixedly connected with a plurality of nozzles 67 to facilitate cooling the side grooves. The outer wall of the extrusion plate 62 is fixedly connected with a third sandpaper rod 68 that fits the groove of the side wall of the aluminum profile body 7.

[0050] Specifically, during transportation, first add coolant to the coolant tank 2, and select different first cooling mechanisms 5 and second cooling mechanisms 6 for installation according to the shape and size of the aluminum profile body 7. It should be noted that the upper pressing plate 63 and the lower supporting plate 65 are fixed and replaceable with screws. After the extruded aluminum profile body 7 falls on the conveyor belt 13, the driving mechanism works to drive the conveyor belt 13 to move, and the aluminum profile body 7 first enters the first cooling mechanism 5. The circulating cooling mechanism cools down the aluminum profile body 7 inside the first cooling mechanism 5 and removes burrs on the outer side of the aluminum profile body 7. At the same time, during transportation, During the feeding process, the side grinding mechanism 4 trims the side of the aluminum profile body 7 and limits the position to ensure that the aluminum profile body 7 can accurately enter the second cooling mechanism 6 for cooling. When entering the first cooling mechanism 5, the coolant is sprayed out from the spray holes 54 on the side plates 53 and the upper shower plate 52 through the circulating cooling mechanism to complete the external preliminary cooling. When entering the second cooling mechanism 6, the first sandpaper rod 64, the second sandpaper rod 66 and the third sandpaper rod 68 are respectively inserted into the corresponding grooves of the aluminum profile body 7 to remove burrs to ensure the quality of burr removal, and the nozzle 67 cools the side grooves.

[0051] Reference Figure 5 and Figure 7 Specifically, in the embodiment of the present invention, a bottom portion of the lower support plate 65 close to the first cooling mechanism 5 is fixedly connected with an inclined sliding plate 651, and the upper pressing plate 63 and the lower support plate 65 are in contact with the outer wall of the aluminum profile body 7, and frosted particles are provided on the surface.

[0052] During the conveying process, the setting of the sliding plate 651 facilitates the aluminum profile body 7 to enter between the upper pressing plate 63 and the lower supporting plate 65 to complete the targeted burr treatment, such as Figure 5 As shown, the aluminum profile body 7 with rounded corners can be rounded to prevent burrs at the rounded corners and improve the deburring effect.

[0053] Reference Figure 1-Figure 3 Specifically, in the embodiment of the present invention, the circulating cooling mechanism includes an infusion pipe 31 and a connecting pipe 32, one end of the infusion pipe 31 is connected to the coolant tank 2, and the other end is fixedly connected to the connecting pipe 32, and a boost pump 33 is provided on the infusion pipe 31, and an electromagnetic multi-way valve 34 is fixedly connected to the connecting pipe 32, and the electromagnetic multi-way valve 34 is respectively located in the first limit block 51 and the second limit block 69, and the output end of the electromagnetic multi-way valve 34 located in the first limit block 51 is respectively connected to the upper shower plate 52 and the side plate 53 pipeline, and the output end of the electromagnetic multi-way valve 34 located in the second limit block 69 is connected to the transfer pipe 61 pipeline.

[0054] When cooling is performed, the boost pump 33 is started. Under the action of the boost pump 33, the coolant in the coolant tank 2 can flow into the electromagnetic multi-way valve 34 through the infusion pipe 31 and the connecting pipe 32, and then the electromagnetic multi-way valve 34 performs diversion. The coolant is transported to the upper shower plate 52, the side plate 53 or the transfer pipe 61 through pipeline transportation to complete the spraying of the coolant and achieve cooling of the aluminum profile body 7.

[0055] Reference Figure 3 Specifically, in the embodiment of the present invention, both ends of the coolant tank 2 are fixedly connected with an inclined feed pipe 21, the sum of the lengths of the coolant tank 2 and the feed pipe 21 is greater than the length of the conveyor belt 13, and a filter screen 22 is arranged in the coolant tank 2, and the filter screen 22 is an H-shaped structure.

[0056] When in use, coolant is added from the feed pipe 21, and the amount of coolant is convenient to observe. During transportation, the used coolant falls into the coolant tank 2 from both sides of the conveyor belt 13 and both ends of the conveyor belt 13. The used coolant is filtered by the filter screen 22 and returned for secondary utilization. Specifically, the vertical part of the filter screen 22 filters the coolant returning from both sides, and the horizontal part filters the coolant falling from above, so as to prevent the secondary coolant from clogging the pipeline.

[0058] When driving, the motor 11 is started to drive the transmission wheel set 12 to work, the transmission wheel set 12 drives the rotating roller to rotate, and then drives the conveyor belt 13 to move to complete the transportation. It should be noted that the conveyor belt 13 here is made of high temperature resistant material to prevent the extruded aluminum profile body 7 from damaging the conveyor belt 13.

[0059] Reference Figure 1 and Figure 2 Specifically, in the embodiment of the present invention, the side grinding mechanism 4 includes a sliding rod 41 and a locking tube 42, the locking tube 42 is detachably connected to the outer top wall of the bracket 1, the sliding rod 41 is slidably connected to the locking tube 42, one end of the sliding rod 41 is rotatably hinged with a hinge 43, and the hinge 43 is fixedly connected to a connecting sticker 44 on the side away from the sliding rod 41, and the connecting sticker 44 is detachably connected to a sandpaper belt 45.

[0060] Before transportation, the distance of the sliding rod 41 is adjusted according to the size of the aluminum profile body 7 to be transported, and then the sliding rod 41 and the locking tube 42 are locked with screws. When the aluminum profile body 7 is being transported, the sandpaper belt 45 is in contact with the aluminum profile body 7 to clean the burrs on the surface of the aluminum profile body 7. In order to facilitate the control of the sliding rod 41 and the locking tube 42, the screws between the locking tube 42 and the sliding rod 41 can be removed, and a cylinder for controlling the movement of the sliding rod 41 can be connected to the locking tube 42 (existing technology, no further elaboration is required).
