Detailed Description
The technical solution of the present application will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1 and 2, an automatic production system for foamed pipe fittings of an outer sheath of high density polyethylene disclosed in an embodiment of the present application is composed of a workbench 11, an extrusion die 12, a rail 13, an extruder 14, a cutting module 2, a first transportation module 3, a second transportation module 4, and the like, specifically, the workbench 11 is placed on a horizontal plane, the extrusion die 12, the rail 13, and the extruder 14 are all fixedly mounted on the workbench 11, and the extrusion die 12 is located between the rail 13 and the extruder 14.
The input end of the extrusion die 12 is connected with the output end of the extruder 14, in the production process, the extruder 14 sends the processed raw materials into the extrusion die 12, and the raw materials flow out from the output end of the extrusion die 12 after being molded in the extrusion die 12.
The track 13 is provided with a first transport module 3 and a second transport module 4, which serve to lift the pipe emerging from the extrusion die 12. The rail 13 is further provided with a cutting module 2 for cutting the pipe flowing out of the extrusion die 12 according to the instruction.
The cutting die set 2 can also move on the rail 13, and specifically, during the process of cutting the pipe, the cutting die set 2 moves along with the movement of the cutting slit on the pipe, and remains stationary relative to the pipe, that is, the cutting process does not affect the extrusion speed of the extrusion die 12.
Referring to fig. 3, a speed sensor 51 is further installed on the extrusion die 12, and the speed sensor 51 is used for feeding back the moving speed of the pipe to the cutting module 2, the first transporting module 3 and the second transporting module 4, so that the moving speed of the cutting module 2, the first transporting module 3 and the second transporting module 4 can be matched with the extrusion speed of the pipe.
Meanwhile, the distance measuring sensor 52 is further installed on the cutting module 2, the distance measuring sensor 52 is used for calculating the cutting length of the pipe, for example, the cutting module 2 can move on the rail 13 when the pipe is cut, at this time, the distance measuring sensor 52 and the pipe are in a relatively static state, but when the cutting module 2 resets and waits for the next cutting process, the distance measuring sensor 52 can continuously calculate the relative position change between the cutting module 2 and the pipe, so that the actual extrusion length of the pipe is calculated, and the cutting module 2 is guided to complete the next cutting.
In some possible implementations, the cutting module 2, the first transport module 3 and the second transport module 4 each have a separate control unit using a programmable logic controller, which has the advantage of not deploying too many cables and control cables.
In conjunction with a specific process, when the pipe begins to be extruded in the extrusion die 12, the extruded pipe first contacts the distance measuring sensor 52 on the cutting die set 2, and at this time, the distance measuring sensor 52 begins to calculate the extending length of the pipe.
In this process, the speed sensor 51 on the extrusion die 12 operates simultaneously to feed back the extrusion speed of the pipe to the cutting module 2, the first transport module 3, and the second transport module 4.
During the extrusion of the pipe, the second transportation module 4 will support the end of the pipe far from the extrusion die 12 and move on the rail 13 at the same time, and the moving speed of the second transportation module 4 on the rail 13 is consistent with the extrusion speed of the pipe.
After the extrusion length of the pipe reaches the requirement, the first transportation module 3 is started to support the pipe and move on the rail 13 at the same time, and the moving speed of the first transportation module 3 on the rail 13 is consistent with the extrusion speed of the pipe.
At the same time as the first transport module 3 is started, the cutting module 2 is started and starts to move on the track 13, where the speed of movement of the cutting module 2 is kept the same as the speed of extrusion of the pipe. The cutting die set 2 cuts off the pipe during the movement.
For convenience of description, the cut pipe is referred to as a pipe, after both ends of the pipe are lifted by the first transportation module 3 and the second transportation module 4, the pipe can be rapidly moved to the unloading area under the transportation of the first transportation module 3 and the second transportation module 4, and after the unloading is completed, the first transportation module 3 and the second transportation module 4 are rapidly reset and the above process is repeated.
For the resetting of the first transportation module 3 and the second transportation module 4, it should be noted here that the first transportation module 3 does not need to work for a while after being reset, and therefore can be directly moved to the original position and wait for the next start, but the second transportation module 4 needs to synchronously lift one end of the pipe far away from the extrusion mold 12 during the resetting process, in order to realize the flexible change of the position, the following scheme is used,
install infrared ranging unit 5 additional on second transportation module 4, the second transportation module 4 resets the in-process, and infrared ranging unit 5 starts, and at this moment, the data that infrared ranging unit 5 fed back are marked as S1, and when the pipe fitting appeared in the top of infrared ranging unit 5, the data that infrared ranging unit 5 fed back are marked as S2, and it is obvious, and the numerical value of S2 can be obviously less than the numerical value of S1.
That is, when the feedback data of the infrared ranging unit 5 rapidly drops, the second transporting module 4 stops moving and starts lifting, and then starts moving on the rail 13 according to the feedback data of the speed sensor 51.
