In the fields of printing and the like, such as wallpaper printing, newspaper printing, posters and the like, a plate roller is an important part. Plate making is needed before the plate roller is used, and different patterns or characters and the like are formed on the surface of the plate roller, so that subsequent printing is facilitated. Laser plate making is adopted in the plate making industry at present, laser black glue (mainly coated on the surface of a plate roller, which is convenient for a subsequent laser machine to carve and process patterns or characters and remove redundant black glue covering objects after processing) is used as an indispensable consumable material in the laser plate making link, and the quality of the laser black glue directly influences the production quality and yield of the plate roller. At present, the black glue is mainly combined with a plate roller in a glue hanging mode in the using process, and old glue is continuously formed in the glue hanging (coating) process (the old glue generated in the original plate surface is removed, and the old glue generated in the new plate manufacturing process is dripped or modified). Because the black glue has higher cost and can be repeatedly used, the old glue is repeatedly used in the laser plate making, and the purposes of recycling resources and saving production cost are achieved.

Before the old black glue is reused, the performance of the new glue cannot be achieved due to the series of problems of caking and the like, so the old black glue can be reused only by being crushed into powder (the performance of the new glue can be achieved after being ground).

The black glue powder after putting into the scrap rubber and taking out the smashing at every turn, operating personnel all rotate down electric grinding mechanism earlier and then operate, because electric grinding mechanism weight is heavier, all can bring inconvenience for operating personnel when consequently rotating down and follow-up installation electric grinding mechanism. And when an operator puts a certain amount of waste rubber into the crushing bin at each time and needs to crush the waste rubber with a certain amount in the crushing bin, the operator operates the electric crushing mechanism of the electric black rubber crusher to crush the waste rubber (manually presses a power switch of the electric crushing mechanism), so that the aim of intelligent control cannot be fulfilled. And smash the interior cull volume of storehouse enough, when operating personnel forgot to operate electronic rubbing crusher structure because of various reasons, then can bring the influence for adding the cull next time (if the cull volume is enough not smashed, just can put into the cull again after smashing, smashing the interior cull of storehouse earlier before adding the cull next time, also can cause production efficiency to reduce relatively like this).

When the amount of the waste glue in the crushing bin 103 is enough and the infrared beam emitted by a detection head of the photoelectric switch A1 is shielded, the 3 pin of the photoelectric switch A1 can output high level under the action of the internal circuit thereof, and then the high level enters the 3 pin (4 pin is normally open with the 4 pin of the stabilized voltage power supply A) of the relay timing switch module finished product A2 and the other end of the resistor R1, and then the relay timing switch module finished product A2 can be triggered by a power supply signal. After 3 and 4 feet of relay time switch module finished product A2 were triggered by the power, under the effect of 5 feet output power supply time that its internal circuit and technical staff set for, 5 feet of relay time switch module finished product A2 can be at a certain time (for example 1 minute, concrete time technical staff adjusts according to the crushing time of black glue) output power supply entering relay K1 power input both ends, and then, relay K1 gets electric actuation its control power input end and normally open contact end closure. Because the normally open contact end of the relay K1 (one pole of the 220V alternating current power supply and the control power supply input end of the relay K1 are normally open), the other pole of the 220V alternating current power supply and the two ends of the power supply input end of the electric crushing mechanism M are respectively connected, the electric crushing mechanism M can work to drive the crushing blade 102 to rotate at a high speed and crush the waste rubber in the crushing bin 103 into powder within one minute. When the black glue in the crushing bin is crushed to a height lower than the height of the emitting head of the photoelectric switch A1, the pin 3 of the photoelectric switch A1 does not output high level any more and enters the pin 3 of the finished product A2 of the relay timing switch module, the pin 5 of the finished product A2 of the relay timing switch module stops outputting after 1 minute of power supply, and the electric crushing mechanism M stops working. When the user puts the waste rubber material into the crushing bin 103 next time, the waste rubber material shields the emitting head of the photoelectric switch A1 again, and the electric crushing mechanism M crushes the waste rubber material and the rubber powder and is higher than the infrared light beam emitted by the emitting head of the photoelectric switch A1, the electric crushing mechanism M stops working; because photoelectric switch A1's 3 feet keep exporting the high level and get into the resistance R1 other end, like this, after the high level entered the anodal power input end of emitting diode VL through resistance R1 step-down current-limiting, emitting diode VL will have the electroluminescence to give the suggestion to the user, smash the interior cull volume of storehouse 103 and be enough, in time take out the black glue powder after smashing, prevent to put into the cull subsequently and cause the influence. This is novel because a rubber powder section of thick bamboo 8 and crushing storehouse 103 are connected through the magnet actuation, not only take off and the actuation is convenient, and because upper and lower magnet actuation is inseparable, can prevent that the rubber powder from wafting to the air in. This is novel can bring the facility and have certain intellectuality for operating personnel, has increased the market competition of product. The resistance of the resistor R1 is 1.9K; the light emitting diode VL is a red light emitting diode; relay K1 is a DC4100 type 12V relay. This novel use a period of time after, the adhesive powder of detachable photoelectric switch A1 with the detecting head front end adhesion is clear away, prevents to bring the influence to photoelectric switch A normal work.
