Description

3D printer buffer stop
Technical Field
The utility model relates to a 3D printing technique, especially a 3D printer buffer stop.
Background
At present, 3D printers on the market can not effectively prevent a printing head from colliding with a printing bottom plate, often, due to the fact that leveling parameters are set incorrectly or parameters are lost, the printing head collides with the bottom plate, or the printing head is damaged, or the printing bottom plate is scratched, the printing bottom plate is uneven, printing quality is affected, and in more serious cases, the mechanical structure of the printer can be damaged. The device can effectively avoid the problems by simply adjusting the screw in the structure.
Disclosure of Invention
The utility model discloses an aim at solving the problem among the prior art, provide a 3D printer buffer stop, can solve the problem of proposing in the background art.
The utility model provides a technical scheme that its technical problem adopted is: including fixed plate and micro-gap switch, fixed plate department installs adjusting part, adjusting part is used for touching micro-gap switch when beating printer head nozzle and printing the bottom plate and be about to contact, micro-gap switch department is connected with the signal line, and this signal line establishes ties in the power-off protection circuit of printer.
Adopt above-mentioned technical scheme, establish ties in the power-off protection circuit of printer through setting up a micro-gap switch, be provided with an adjusting part simultaneously, when beating printer head nozzle and printing the bottom plate and be about to contact, through adjusting part touching micro-gap switch for the micro-gap switch starts, and in signal transmission to power-off protection circuit through the signal line, finally starts power-off protection circuit, makes 3D printer stop operation, can avoid beating printer head nozzle and printing the collision of bottom plate.
Further setting the following steps: the adjusting component comprises a locking screw and a plurality of adjusting screws which are arranged on the fixing plate, fine adjusting plates are arranged at the lower ends of the locking screw and the adjusting screws, and a coarse adjusting block is arranged at one end of each fine adjusting plate.
Adopt above-mentioned technical scheme, through adjusting part's setting, can simple effectual realization, the thick adjusting block of adjusting part touches micro-gap switch earlier when beating printer head nozzle and printing the bottom plate and be about to contact.
The method is further provided with the following steps: the fixing plate is fixedly arranged on a support which moves up and down along with the printing bottom plate.
The method is further provided with the following steps: the micro switch is fixedly arranged at a fixing plate connected with the printing head.
The utility model has the advantages that: the utility model relates to a 3D printer buffer stop's design can effectual solution beat printer head and print the bottom plate and collide to lead to beating printer head and bottom plate and colliding, perhaps destroy and beat printer head, perhaps the scratch prints the bottom plate, leads to printing the bottom plate not flat, the whole quality of printing that influences, can destroy the mechanical structure's of printer problem when more serious.
Drawings
FIG. 1 is a schematic diagram of an embodiment of the present invention;
fig. 2 is a schematic structural diagram of an adjusting assembly according to an embodiment of the present invention.
In the figure, a fixing plate 1, a locking screw 2, an adjusting screw 3, a microswitch 4, a fine adjusting plate 5, a coarse adjusting block 6, a printing bottom plate 7, a printing head 8 and an adjusting component 9 are arranged.
Detailed Description
The invention will be further described with reference to the accompanying drawings:
as shown in fig. 1 and 2, the present embodiment includes a fixing plate 1 and a micro switch 4, where an adjusting component 9 is installed at the fixing plate 1, the adjusting component 9 is used for touching the micro switch 4 when a nozzle of a printing head 8 is about to contact with a printing bottom plate 7, and the micro switch 4 is connected with a signal line, and the signal line is connected in series in a power-off protection circuit of a printer. This adjusting part 9 is including installing locking screw 2 and a plurality of adjusting screw 3 on fixed plate 1, and fine setting board 5 is installed to this locking screw 2 and a plurality of adjusting screw 3 lower extreme, thick adjusting block 6 is installed to fine setting board 5 one end. The fixing plate 1 is fixedly arranged on a support which moves up and down along with the printing bottom plate 7. The microswitch 4 is fixedly arranged at the fixing plate 1 connected with the printing head 8.
In the device, an assembly connected with a fixed plate 1 is fixedly arranged on a structural member which moves up and down with a printing bottom plate 7 at the same time, a microswitch 4 is fixedly arranged on the fixed plate 1 connected with a printing head 8 and is static relative to the Z-axis direction of the printing head 8, and a signal wire is connected with a normally closed contact of the microswitch 4 and is connected in series in a power-off protection circuit of a printer.
The utility model discloses in the course of the work, the adjustment method does: when the Z axis of the 3D printer returns to a system 0 point (namely a nozzle of a printing head 8 is just contacted with a printing bottom plate 7), firstly adjusting a coarse adjusting block 6 to enable the coarse adjusting block to be close to a microswitch 4; the adjusting screw 3 is adjusted while the locking screw 2 is loosened until the printer is power-off protected, and the printer retracts 1/4 turns of threads and locks the locking screw 2. Adjusting the OFFSETZ value to ensure that the increment of the value of the printing head 8 close to the printing bottom plate 7 is equal to the system point, the printing head 8 is about to impact the printing bottom plate 7, and the micro switch 4 acts to generate power-off protection; and manually moving the Z axis to enable the microswitch 4 to be switched on, adjusting back the OFFSETZ value again, returning to the 0 point of the system again, enabling the printing head 8 not to impact the printing bottom plate 7, and enabling the microswitch 4 not to act to generate power-off protection.
The utility model relates to a 3D printer buffer stop's design can effectual solution beat printer head 8 and print bottom plate 7 and collide to lead to beating printer head 8 and bottom plate and colliding, perhaps destroy and beat printer head 8, perhaps the scratch prints bottom plate 7, leads to printing bottom plate 7 uneven, whole influence printing quality, can destroy the mechanical structure's of printer problem when more serious.
The above-mentioned embodiment is right the utility model discloses an explanation, it is not right the utility model discloses a limited, any right the scheme after the simple transform of the utility model all belongs to the protection scope of the utility model.
