When the printing consumables 100 pass between the first rotating wheel 2 and the second rotating wheel 3, the sliding piece 6 moves towards the mounting block 8, and the sliding piece 6 contacts and presses the micro contact 7, so that the micro switch is switched on. On the contrary, when the printing supplies 100 are absent between the first wheel 2 and the second wheel 3, the second wheel 3 is absent of the thrust of the printing supplies 100, so that the pressure of the slider 6 on the micro-contact 7 is eliminated, and the micro-switch is turned off.
During the use, including three kinds of circumstances to the detection of printing consumables 100, have normal defeated material, lack material or putty respectively, state in this device that three kinds of circumstances correspond explains below:
normal material conveying: the printing consumables 100 are normally moved and output, the first rotating wheel 2 and the second rotating wheel 3 are normally rotated, the sliding part 6 presses the micro contact 7, and the photoelectric sensor 5 detects a periodically-changed signal, which indicates that the printing consumables 100 are normally output.
Material shortage: the printing consumables 100 are missing and do not enter between the first wheel 2 and the second wheel 3, the micro-contact 7 is opened, and the first wheel 2 stops rotating due to the missing of the printing consumables 100, so that the code disc 4 also stops rotating, and the photoelectric sensor 5 detects a constant signal which does not change, which indicates that the printing consumables 100 are missing.
Thirdly, material blocking: the printing consumables 100 jam and stop moving, at this time, although the sliding piece 6 presses the micro contact 7, the first rotating wheel 2 stops rotating due to the stop moving of the printing consumables 100, so that the code disc 4 also stops rotating, and the photoelectric sensor 5 detects a constant signal without change.
It can be understood that, can be through connecting a controller, for example 51 singlechip or 3D printer's control system, connect photoelectric sensor 5 and micro-gap switch, when photoelectric sensor 5 received periodic variation's signal and micro-gap switch and switched on simultaneously, just show the normal defeated material of printing consumables 100, otherwise show that there is the problem (putty or lack of material) in the output of present printing consumables 100, because the detection decision mechanism of setting means is come to the testing result through the sensor, common custom control sets for, the reason is no longer repeated here.
It will be appreciated that the mounting block 8 may alternatively be fixed within the housing 1, or the manner in which the mounting block 8 is slidably connected to the housing 1 may also be selected, in this embodiment, the mounting block 8 is slidably connected to the housing 1.
It is understood that, in the present embodiment, the micro-contact 7 and the mounting block 8 constitute a micro-switch, for example, a common micro-switch device with a model number of D2FC-F-7N, D2FC-FL-NH or D2 FC-F-K.
Referring to fig. 2, a first sliding groove 11 is formed in the housing 1 at a position corresponding to the sliding member 6, a second sliding groove 12 is formed in the housing corresponding to the mounting block 8, two sides of the sliding member 6 are in contact with the first sliding groove 11, two sides of the mounting block 8 are in contact with the second sliding groove 12, a boss 13 is formed between the first sliding groove 11 and the second sliding groove 12, and the boss 13 is used for limiting the sliding range of the mounting block 8 to prevent the micro switch from being triggered in the case of material shortage.
Referring to fig. 2, a through hole 14 and a sleeve 15 are disposed in the casing 1, the sleeve 15 is disposed coaxially with the through hole 14, a cut-off portion is disposed at a position of the sleeve 15 corresponding to the first rotating wheel 2 and the second rotating wheel 3, and the printing consumable 100 passes through the through hole 14 and the sleeve 15 and contacts with the first rotating wheel 2 and the second rotating wheel 3 at the cut-off portion.
