Description

Technical Field

[0001] This utility model relates to the field of powder packaging machine technology, and in particular to a silicon carbide micro powder packaging machine. Background Technology

[0002] Silicon carbide micron powder refers to micron-sized silicon carbide powder that has undergone ultrafine grinding and classification using JZFZ equipment. Silicon carbide micron powder is mainly available in 1200# and 1500# grades. Because silicon carbide micron powder is primarily used in the abrasive industry, there are specific requirements for its classification; large particles must not be present. Therefore, to meet international and domestic product requirements, high-precision classification using JZF classification equipment is generally employed in production. Domestically produced silicon carbide micron powder is mainly available in black and green varieties.

[0003] Patent document CN221251816U discloses the technical field of silicon carbide micro powder packaging machine, specifically disclosing a silicon carbide micro powder packaging machine, including a silicon carbide micro powder filling machine body, a feed inlet located at the top of the silicon carbide micro powder packaging machine, a discharge outlet located at the bottom of the silicon carbide micro powder packaging machine, and a switching valve for controlling the flow rate of the discharge outlet; it also includes a dustproof component detachably connected to the discharge outlet, the dustproof component including a cylinder, a cavity fixed around the cylinder to form an isosceles trapezoidal block with the cylinder, and a connecting groove on the cylinder that is detachably connected to the discharge outlet, the bottom surface of the connecting groove being set as an inclined surface, the two side walls of the connecting groove having connecting holes communicating with the cavity, and the bottom of the cavity communicating with several outflow pipes, the outflow pipes being placed inside the packaging bag. This device solves the problem that traditional silicon carbide micro powder packaging machines do not have a dustproof effect at the discharge outlet, thus affecting the workshop environment.

[0004] In actual use, the above solution lacks a mechanism to fix the packaging bag at the discharge port, which means that external rubber bands or ropes are still needed to fix the packaging bag to the discharge port, making the operation cumbersome. Utility Model Content

[0005] This utility model discloses a silicon carbide micro powder packaging machine, which aims to solve the technical problem of existing powder packaging machines lacking fixed packaging bags.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A silicon carbide micro powder packaging machine includes a filling machine body, a discharge pipe is provided below the filling machine body, a fixing mechanism is provided on the surface of the discharge pipe, and a dustproof mechanism is provided below the filling machine body.

[0008] The fixing mechanism includes an internal thread on the surface of the discharge pipe, a threaded sleeve is threadedly connected to the surface of the discharge pipe through the internal thread, a fixing cap is rotatably connected to the lower end of the threaded sleeve, and an abutment is provided on the lower end surface of the discharge pipe.

[0009] In a preferred embodiment, a silicone gasket is embedded in the upper surface of the abutment.

[0010] The silicone gaskets protect the packaging bag when the cap is pressed against it.

[0011] In a preferred embodiment, a powder sensor is embedded in the surface of the discharge pipe.

[0012] By setting up a powder sensor, the amount of powder conveyed in the discharge pipe can be controlled.

[0013] In a preferred embodiment, the dustproof mechanism includes an annular tube fixedly installed on the lower surface of the filling machine body. The inner annular surface of the annular tube has a dust suction hole. A fan and a filter box are fixedly installed on the right side surface of the filling machine body. The filter box has a filter screen plate slidably connected to it by a slide rail. The exhaust end of the fan extends into the interior of the filter box. The lower surface of the filter box is provided with a pipe communicating with the interior of the annular tube.

[0014] In a preferred embodiment, the number of suction holes is several, and the several suction holes are arranged in a circumferential array on the inner ring surface of the annular tube.

[0015] In a preferred embodiment, the right side surface of the filter box is rotatably connected to a limiting block for restricting the filter screen via a rotating seat.

[0016] As can be seen from the above, the silicon carbide micro powder packaging machine provided by this utility model has the following technical effects.

[0017] Firstly, the packaging bag is placed on the discharge pipe, and the fixed cover is moved down by rotating the threaded sleeve through the internal thread until the fixed cover closes with the edge, fixing the bag opening on it. At this time, the filling work can be carried out. When removing the packaging bag, the threaded sleeve is reversed to separate the fixed cover from the edge, and the packaging bag can be removed, which provides convenience for the loading and unloading of the packaging bag.

[0018] Secondly, under the operation of the fan, the annular pipe generates suction force through the filter box and pipeline. After the annular pipe generates suction force, the powder mist overflowing during the filling of the filling machine body is drawn into the filter box and filtered through the filter screen plate, so that the device can achieve the effect of dust prevention and avoid dust generation.
