Detailed Description
The technical solutions in the present application are described in further detail below with reference to the accompanying drawings.
Referring to fig. 1 and 2, in order to disclose an automatic production system for a high-density polyethylene outer protection pipe foaming pipe according to an embodiment of the present application, the system is composed of a workbench 11, an extrusion die 12, a rail 13, an extruder 14, a cutting die set 2, a first transportation die set 3, a second transportation die set 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 fixedly installed 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, and 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 rail 13 is provided with a first transport module 3 and a second transport module 4, which serve to lift the pipe flowing out of the extrusion die 12. The rail 13 is also provided with a cutting module 2 for cutting the pipe flowing out of the extrusion die 12 according to instructions.
The cutting module 2 can also move on the rail 13, specifically, the cutting module 2 moves along with the movement of the cutting slit on the pipe during the cutting process of the pipe, and remains relatively stationary with the pipe, that is, the extrusion speed of the extrusion die 12 is not affected during the cutting process.
Referring to fig. 3, the extrusion die 12 is further provided with a speed sensor 51, and the speed sensor 51 is used for feeding back the moving speeds of the pipe to the cutting die set 2, the first transporting die set 3 and the second transporting die set 4, so that the moving speeds of the cutting die set 2, the first transporting die set 3 and the second transporting die set 4 can be matched with the extrusion speeds 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 fitting, for example, the cutting module 2 moves on the track 13 when the pipe fitting is cut, the distance measuring sensor 52 and the pipe fitting are in a relatively static state at the moment, but when the cutting module 2 is reset 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 fitting, so that the actual extrusion length of the pipe fitting is calculated, and the cutting module 2 is used for guiding the cutting module 2 to complete the next cutting process.
In some possible implementations, the cutting module 2, the first transport module 3 and the second transport module 4 each have independent control units, which use programmable logic controllers, which has the advantage that no excessive cables and control cables are deployed.
In connection with a particular process, when the extrusion of a tube is initiated in the extrusion die 12, the extruded tube will first come into contact with the distance sensor 52 on the cutting die set 2, at which point the distance sensor 52 begins to calculate the tube extension.
In this process, the speed sensor 51 on the extrusion die 12 operates simultaneously, feeding back the extrusion speed of the pipe to the cutting die set 2, the first transporting die set 3 and the second transporting die set 4.
In the pipe extrusion process, the second transporting module 4 holds the pipe away from the end of the extrusion die 12 and moves on the rail 13 at the same time, and the moving speed of the second transporting module 4 on the rail 13 is consistent with the extrusion speed of the pipe.
After the extrusion length of the pipe fitting reaches the requirement, the first transportation module 3 is started to hold the pipe fitting and move on the track 13 at the same time, and the moving speed of the first transportation module 3 on the track 13 is consistent with the extrusion speed of the pipe fitting.
At the same time as the first transport module 3 is started, the cutting module 2 is started and starts to move on the rail 13, where the movement speed of the cutting module 2 is kept consistent with the extrusion speed of the pipe. The cutting module 2 cuts off the pipe during the movement.
For convenience of description, the cut pipe is called a pipe, two ends of the pipe are lifted by the first transport module 3 and the second transport module 4, and then the pipe can be quickly moved to a discharging area under the transportation of the first transport module 3 and the second transport module 4, and after the discharging is completed, the first transport module 3 and the second transport module 4 are quickly reset and the above process is repeated.
For the resetting of the first transport module 3 and the second transport module 4, it should be noted here that the first transport module 3 needs to be not operated for a certain period of time after resetting, so that the first transport module 3 can be directly moved to the original position and then wait for the next starting, but the second transport module 4 needs to synchronously lift one end of the pipe away from the extrusion die 12 in the resetting process, in order to realize the flexible change of the position, the following scheme is used,
the infrared ranging unit 5 is additionally arranged on the second transportation module 4, the infrared ranging unit 5 is started in the resetting process of the second transportation module 4, at this time, the data fed back by the infrared ranging unit 5 are recorded as S1, when a pipe fitting appears above the infrared ranging unit 5, the data fed back by the infrared ranging unit 5 are recorded as S2, and obviously, the numerical value of S2 can be obviously smaller than that of S1.
That is, when the feedback data of the infrared ranging unit 5 is rapidly lowered, 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.
