Abstract
Description
- The technical field relates to a nozzle head cleaning module for a heat-melting type three-dimensional printer and, in particular, to a hidden type nozzle head cleaning module.
- Usually, a three-dimensional (3D) printer with a coloring function has a formation nozzle head for extruding a melted material and also has a coloring nozzle head for coloring. Therefore, the 3D printer is provided with a cleaning module for cleaning the coloring nozzle head and a cover set module which is used to cover the coloring nozzle head to prevent ink from drying out when the 3D printer is not in use. Normally, the cleaning module includes a scraper protruding out of a formation plane, and the coloring nozzle head moves to the scraper to rub against the scraper for cleaning. The cover set module can ascend or descend, and at least a portion of the cover set module protrudes out of the formation plane, so that the coloring nozzle head can push to raise a cover of the cover set module.
- At least the above-mentioned components are protrudingly disposed on the formation plane. During a printing process, the formation nozzle head or the coloring nozzle head should not interfere with the above-mentioned protruding components. When the formation nozzle head moves to an edge of the formation plane, the coloring nozzle head may exceed an area of the formation plane to interfere with the above-mentioned protruding components. Therefore, the formation nozzle head in particular movement courses is not allowed to move to the edge of the formation plane, and consequently, a portion of the area of the formation plane cannot be used for printing a product, and thereby a size of the finished product is limited.
- The scraper and the cover are not associated. Therefore, to receive the scraper and the cover below the formation plane, two sets of a motor and gears are required for driving the scraper and the cover, respectively, which leads to a larger overall size and higher production costs.
- In views of this, in order to solve the above disadvantage, the inventor studied related technology and provided a reasonable and effective solution in the present disclosure.
- The disclosure is directed to a hidden-type nozzle head cleaning module.
- One of the exemplary embodiments, the disclosure is directed to a nozzle head cleaning module, including a base housing, a main carrier, a sub-carrier and an interference structure. The base housing includes a main slope, and a set of horizontal planes is formed on the main slope. The main carrier is received in the base housing, a scraper protrudes upwardly from the main carrier, a set of main slide pins in contact with the main slope protrudes from the main carrier, the main carrier includes a sub-slope, the main carrier is lifted or lowered obliquely along the main slope with respect to the base housing so as to lift or lower the scraper. When disposed on the horizontal planes, the main slide pin is in contact with the horizontal plane by multiple contact points. The sub-carrier is accommodated in the main carrier, the movement of the main carrier moves the sub-carrier at the same time, a cover protruding upwardly is arranged on the sub-carrier, and at least a portion of the sub-carrier is in contact with the sub-slope. The interference structure is arranged corresponding to the sub-carrier. When the interference structure is in contact with the sub-carrier while the sub-carrier is moving, the interference structure pushes the sub-carrier to move along the sub-slope with respect to the main carrier, and the cover thereby ascends. When the main slide pins is moved to the horizontal planes, the horizontal planes support the main slide pins to maintain the cover in a raised position.
- In the nozzle head cleaning module according to the present disclosure, the interference structure is disposed inside the base housing.
- In the nozzle head cleaning module according to the present disclosure, the driving assembly is connected to the main carrier to move it. The driving assembly includes a motor and a gear set, and the gear set is operatively associated with the motor and the main carrier. The main carrier includes a rack, and the rack meshes with the gear set. The rack is parallel to the main slope.
- In the nozzle head cleaning module according to the present disclosure, the main slope and the sub-slope are inclined in opposite directions; an upper end of the main slope is arranged corresponding to the interference assembly. A sub-slide pin in contact with the sub-slope protrudes from the sub-carrier. The scraper is ascendable to protrude out of a top surface of the base housing.
- The nozzle head cleaning module according to the present disclosure includes a plurality of cylindrical main slide pins and a plurality of horizontal planes corresponding to the main slide pins respectively. When the main slide pins are disposed on the main slope, the main slide pins are in contact with the main slope. When the main slide pins are disposed on the horizontal planes, the main slide pins are in contact with the horizontal planes respectively.
- The nozzle head cleaning module according to the present disclosure includes a single main slide pin which is a diamond-shaped pillar, and a single horizontal plane corresponding to the main slide pin. The main slide pin includes a first support plane and a second support plane inclined to each other. When the main slide pin is disposed on the main slope, the first support plane is in contact with the main slope. When main slide pin is disposed on the horizontal plane, the second support plane is in contact with the horizontal plane.
- In the nozzle head cleaning module according to the present disclosure, the main carrier moves obliquely, and the movement direction is changed by means of the sub-slope and the interference structure. Therefore, by moving the main carrier solely, the scraper and the cover can ascend or descend vertically. When the main carrier moves to the end of the movement course, the horizontal plane of the main slope of the base housing can support the main carrier, so that the main carrier does not slip down when it stops.

FIGS. 1 to 4 showing a nozzle head cleaning module according to one embodiment of the present disclosure. The nozzle head cleaning module is used in a heat-melting type three dimensional (3D) printer (not illustrated) and is disposed corresponding to aformation plane 10 of the 3D printer. The nozzle head cleaning module includes abase housing 100, amain carrier 200, asub-carrier 300, adriving assembly 400, and aninterference structure 120. - In the present embodiment, the
base housing 100 is a hollow casing however, the present disclosure is not limited to any particular material of thebase housing 100. Thebase housing 100 is fixed to the 3D printer and is disposed at one side of theformation plane 10. Atop surface 101 of thebase housing 100 includes at least one opening 102. Thetop surface 101 of thebase housing 100 is not higher than a level of theformation plane 10. Thetop surface 101 of thebase housing 100 is preferably flush with theformation plane 10, but alternatively thetop surface 101 of thebase housing 100 can be lower than theformation plane 10. At least onemain slope 110 is disposed inside thebase housing 100. In the present embodiment, thebase housing 100 includes twomain slopes 110 with the same structure and functions, a portion of eachmain slope 110 includes a set of one or morehorizontal planes 111, and the set of one or morehorizontal planes 111 includes a single or multiple horizontal planes 111 (in the present embodiment, there are two horizontal planes 111); however, only onemain slope 110 is described hereinafter for simplicity of description. - The
main carrier 200 is received in thebase housing 100, ascraper 230 protrudes upwardly from themain carrier 200, and themain carrier 200 includes at least onesub-slope 220. In the present embodiment, themain carrier 200 includes multiplesame sub-slopes 220. Themain slopes 110 and thesub-slopes 220 are inclined in opposite directions. Arack 201 is obliquely disposed on an outer bottom side of themain carrier 200, and therack 201 is parallel to themain slope 110. At least one set ofmain slide pins 210 protrudes from an outer side surface of themain carrier 200. In the present embodiment, there are two sets of one or moremain slide pins 210 with the same structure and functions, corresponding to the respective twomain slopes 110, protrude from respective outer side surfaces of themain carrier 200. The two sets of one or more main slide pins 210 are respectively in contact with the twomain slopes 110, and each set of one or more main slide pins 210 includes a single or multiple main slide pins 210 (there are two main slide pins 210 in this embodiment), the number of the main slide pins 210 corresponds in number to the number of thehorizontal planes 111, and eachmain slide pin 210 collaborates with eachhorizontal plane 111; however, only one set of one or moremain slide pin 210 is described hereinafter for simplicity of description. When disposed on themain slope 110, the set of one or more main slide pins 210 contacts, along a longitudinal direction of themain slope 110, themain slope 110 by multiple contact points. By supporting multiple main slide pins 210 on themain slope 110, themain carrier 200 is prevented from rotation and maintains the same posture while moving along themain slope 110. When the set of one or more main slide pins 210 is disposed on the set of one or morehorizontal plane 111, the set of one or more main slide pins 210 is in contact with the set of one or morehorizontal planes 111 by multiple contact points. By supporting the main slide pins 210 on thehorizontal plane 111, themain carrier 200 is prevented from rotation and maintains the same posture after moving to thehorizontal plane 111. Themain carrier 200 is lifted or lowered obliquely along themain slope 110 with respect to thebase housing 100 so as to lift or lower thescraper 230. In detail, in the present embodiment, when the set of one or more main slide pins 210 rests on themain slope 110, eachmain slide pin 210 contacts themain slope 110. When themain slide pin 210 rests on thehorizontal plane 111, eachmain slide pin 210 contacts a respective corresponding one of thehorizontal planes 110. - The
sub-carrier 300 is accommodated in themain carrier 200, acover 320 protruding upwardly is arranged on thesub-carrier 300, and at least a portion of thesub-carrier 300 is in contact with the sub-slope 220. At least onesub-slide pin 310 protrudes from an outer side surface of thesub-carrier 300. In the present embodiment, there are multiplesub-slide pins 310 with the same structure and functions, the multiplesub-slide pins 310 protruding from outer side surfaces of thesub-carrier 300 are disposed respectively corresponding to the above-mentionedsub-slopes 220. Eachsub-slide pin 310 is in contact with a respective corresponding one of the sub-slopes 220; however, only onesub-slide pin 310 is described hereinafter for simplicity of description. - The driving
assembly 400 is connected to themain carrier 200 and obliquely lifts or lowers themain carrier 200 with respect to thebase housing 100 to lift or lower thescraper 230, and thescraper 230 is lifted to protrude out of atop surface 101 of thebase housing 100 through theopening 102. In the present embodiment, the drivingassembly 400 includes amotor 410 and agear set 420, themotor 410 is fixed to thebase housing 100, and the gear set 420 is operatively associated with themotor 410 and themain carrier 200. In detail, the gear set 420 is connected to themotor 410 and meshes with therack 201 of themain carrier 200, so themotor 410 can drive themain carrier 200 to ascend or descend along themain slope 110. The movement of themain carrier 200 moves thesub-carrier 300 accommodated inside themain carrier 200 at the same time. - The
interference structure 120 is arranged inside thebase housing 100 corresponding to thesub-carrier 300. In the present embodiment, theinterference structure 120 is a protruding block inside thebase housing 100. A top end of themain slope 110 is arranged corresponding to theinterference structure 120. When theinterference structure 120 is in contact with thesub-carrier 300 while thesub-carrier 300 is moving, theinterference structure 120 blocks thesub-carrier 300 and maintains a horizontal position of thesub-carrier 300. Once themain carrier 200 continues to move toward theinterference structure 120, theinterference structure 120 pushes the sub-carrier 300 to move along the sub-slope 220 with respect to themain carrier 200, and thecover 320 thereby ascends. Thecover 320 ascends to pass through theopening 102 to protrude out of thetop surface 101 of thebase casing 100. - Referring to
FIGS. 3 to 5 , in the present embodiment, thetop surface 101 of thebase housing 100 is flush with theformation plane 10. When the 3D printer is in operation, themain carrier 200 is at a lower end of themain slope 110, and thescraper 230 is received in thebase housing 100 and is disposed below thetop surface 101 of thebase housing 100. In addition to that, thesub-carrier 300 is at a lower end of the sub-slope 220, and thecover 320 is received in themain carrier 200 and is disposed below thetop surface 101 of thebase housing 100. Therefore, during printing operation, acoloring head 20 is allowed to move beyond theformation plane 10, so there is more room available for use on theformation plane 10. - To clean the
coloring head 20, themain carrier 200 is driven by themotor 410 to ascend along themain slope 110 toward theinterference structure 120, so that thescraper 230 protrudes out of thetop surface 101 of thebase housing 100. At this point, thesub-carrier 300 does not yet touch theinterference structure 120, and thecover 320 is still received inside themain carrier 200 and is disposed below thetop surface 101 of thebase housing 100. Then, thecoloring head 20 is moved to contact thescraper 230, and thecoloring head 20 is moved back and forth for cleaning. - Referring to
FIGS. 6 to 8 , after cleaning, thecoloring head 20 is moved to a standby position, the standby position is arranged corresponding to a position of theinterference structure 120. Themotor 410 continues to drive themain carrier 200 to move toward theinterference structure 120 along themain slope 110. When the sub-carrier 300 touches theinterference structure 120, thesub-carrier 300 is blocked from moving horizontally by theinterference structure 120, and thecover 320 is at a standby position. Themotor 410 continues driving themain carrier 200 to move toward theinterference structure 120 along themain slope 110, and thesub-carrier 300 is pushed by theinterference structure 120 to an upper end of the sub-slope 220 to vertically raise thecover 320 to cover thecoloring head 20. When the set of one or more main slide pins 210 moves to the set of one or morehorizontal planes 111, the set of one or morehorizontal planes 111 support the set of one or more main slide pins 210 to maintain thecover 230 in a raised position. - In the nozzle head cleaning module according to the present disclosure, the
main carrier 200 is driven by themotor 410 to move obliquely. The oblique movement achieves horizontal displacement and vertical displacement. Due to the vertical displacement, thescraper 230 ascends or descends vertically. By means of theinterference structure 120 and the sub-slope 220, the horizontal displacement of themain carrier 200 is changed to vertical displacement to achieve vertical ascending/descending of thecover 320. Therefore, in the nozzle head cleaning module of the present disclosure, only onemotor 410 is required to drive thescraper 230 and thecover 320 to ascend or descend vertically. Moreover, when themain carrier 200 moves to the end of the movement course, thehorizontal plane 111 of themain slope 110 of thebase housing 100 can support themain carrier 200, so that themain carrier 200 does not slip down when it stops. - Referring to
FIGS. 9 and 10 illustrating the main slide pin according to another embodiment of the present disclosure, the set of one or more main slide pins 210 includes a singlemain slide pin 210 which is a diamond-shaped pillar, and themain slide pin 210 includes afirst support plane 211 and asecond support plane 212 inclined to each other. An included angle included by thefirst support plane 211 and thesecond support plane 212 is equal to an included angle included by themain slope 110 and thehorizontal plane 111. A singlehorizontal plane 111 is formed on an upper end of themain slope 110 and is arranged corresponding to the singlemain slide pin 210. When themain slide pin 210 is disposed on themain slope 110, thefirst support plane 211 is in contact with themain slope 110. By resting thefirst support plane 211 on themain slope 110, themain carrier 200 is prevented from rotation and maintains the same posture while moving along themain slope 110. When themain slide pin 210 rests on thehorizontal plane 111, thesecond support plane 212 is in contact with thehorizontal plane 111. By supporting thesecond support plane 212 on thehorizontal plane 111, themain carrier 200 is prevented from rotation and maintains the same posture after moving to thehorizontal plane 111. - It is to be understood that the above descriptions are merely the preferable embodiments of the present disclosure and are not intended to limit the scope of the present disclosure. Equivalent changes and modifications made in the spirit of the present disclosure are regarded as falling within the scope of the present invention.
