Description

Technical Field

[0001] The utility model relates to the technical field of suction machines, in particular to a suction machine which can prevent material blocking. Background Art

[0002] Suction machines are widely used in the raw material conveying industry for injection molding machines, extruders and other equipment. They are easy to install, simple to use, have strong long-distance conveying capabilities, stable production, and reliable operation. They are auxiliary equipment for achieving fully automated production and can automatically feed materials to the injection molding machine. When the barrel of the plastic central feeding system is short of material, a signal will be given to the suction machine. The suction machine uses the principle of exhaust to convey the plastic raw materials to the barrel of the injection molding machine. When the material reaches a certain level, the suction machine will stop and wait until the material is insufficient to convey again.

[0003] At present, a new type of anti-blocking suction machine, such as the one described in the patent with announcement number CN219971163U, comprises: a motor, the driving end of the motor is fixedly connected with a slot column, the top and bottom outer walls of the slot column are both rotatably connected with a first support plate, the outer wall of the slot column is provided with a corrugated groove, the inner wall of the corrugated groove is slidably connected with a connecting rod, the left end of the connecting rod is fixedly connected with a dredging rod, the rear end of the connecting rod is fixedly connected with a sliding ball, the outer wall of the sliding ball is slidably connected with a slide groove, and the right end of the slide groove is fixedly connected with a second support plate. In this utility model, the motor drives the slot column to rotate, thereby driving the connecting rod to slide in the corrugated groove, that is, it simultaneously drives the dredging rod to do up and down reciprocating motion at the discharge port 4, so as to achieve the purpose of dredging the discharge port. When inspecting the suction pipe, first rotate the suction pipe counterclockwise until the groove is out of the position of the limit strip, and then pull the suction pipe to the right.

[0004] In view of the above-mentioned related technologies, the applicant found that when a new type of anti-blocking suction machine is used, the exhaust fan and the suction pipe cooperate to suck in the plastic raw materials, but when the plastic raw materials enter the storage tank through the opening, it is easy for the lighter plastic raw materials to be directly adsorbed on the filter net at the exhaust port of the exhaust fan. When too much raw material is adsorbed on the filter net, it will affect the exhaust effect of the exhaust fan, thereby reducing the efficiency of the plastic raw materials when passing through the suction pipe, thereby reducing the practicality of the device in use. For this reason, we propose a suction machine with anti-blocking material. Utility Model Content
