An automatic ink stack lifting system for 3D printers

Abstract

This utility model belongs to the field of printer ink stack technology, and in particular to an automatic lifting ink stack for 3D printers. It includes a support platform with a fixed plate on top; an ink pad is mounted on the fixed plate; and two sets of limiting components are located on both sides of the top of the support platform for installing and fixing the ink pad. In this utility model, the positioning pin and the first and second positioning holes effectively limit the rotation of the rotating rod, preventing it from rotating arbitrarily during the lifting of the ink pad, thus improving the overall structural stability. Furthermore, the height of the positioning pin is greater than the height of the insertion pin, preventing the positioning pin from affecting the normal use of the insertion pin and ensuring smooth installation and removal of the ink pad. In addition, the insertion tube fixed to the bottom of the connecting plate and the mounting holes on the support platform provide initial limiting for the ink pad, further improving its stability during lifting.

Description

Technical Field

[0001] This utility model belongs to the field of printer ink stack technology, specifically relating to an automatic lifting ink stack for 3D printers. Background Technology

[0002] 3D printing is the process of transforming a digital model into a physical object, which can be accomplished using a 3D printer.

[0003] In the prior art, Chinese utility model patent with authorization announcement number CN218171803U discloses "a high-precision lifting ink stack". It uses the principle of lead screw, drives the motor to drive the lead screw to rotate, thereby driving the rotating carrier plate to move, thereby driving the driving carrier plate and two sliding plates to move laterally along the sliding space. During the lateral movement of the driving carrier plate, the sliding plates drive the sliding column to move up and down along the vertical sliding through-hole, thereby driving the two driving slide plates to move up and down, thereby driving the bearing platform to move up and down, thus causing the ink pad to move up and down.

[0004] While existing lifting ink stack devices can precisely control the vertical movement of the support platform by controlling the number of clockwise and counterclockwise rotations of the lead screw—meaning that the aforementioned high-precision lifting ink stack precisely controls the longitudinal movement of the support platform by precisely controlling the lateral movement of the drive frame through the drive mechanism—in order to precisely drive the ink pad to the preset position, in actual use, if the ink pad is installed with bolts, more than six components such as the drive slide plate and sliding column need to be disassembled when replacing the ink pad, resulting in a long maintenance time per operation. If a movable placement method is used (such as direct placement), the ink pad will cause lateral displacement due to vibration when the ink stack is frequently raised and lowered, exceeding the precision threshold required for the inkjet head seal. To solve the above problems, this application proposes an automatic lifting ink stack for 3D printers. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides an automatic lifting ink stack for 3D printers, which facilitates ink pad replacement and prevents the ink pad from shifting during the lifting process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic lifting ink stack for a 3D printer, including a support platform.

[0007] A fixing plate is provided on the top of the support platform;

[0008] An ink pad is provided on the fixing plate;

[0009] Two sets of limiting components are disposed on the top two sides of the support platform for the installation and fixation of the ink pad.

[0010] Preferably, the limiting component includes connecting plates fixed on both sides of the ink pad, and each of the two connecting plates is provided with a pair of limiting holes;

[0011] A rotating rod is provided through the bearing platform, and a fixing member is fixed at one end of the rotating rod. The bottom of the fixing member is provided with a pair of pins that are adapted to the limiting hole.

[0012] The outer wall of the rotating rod is fitted with a washer and a spring in sequence, and the two ends of the spring abut against the washer and the bottom of the bearing platform, respectively.

[0013] Preferably, the end of the rotating rod away from the fixing member has a threaded section and is locked by a nut.

[0014] Preferably, the support platform has a pair of storage holes corresponding to the position of the pin.

[0015] Preferably, a positioning pin is fixed on the fixing member, and a first positioning hole and a second positioning hole are provided on the bearing platform. The positioning pin can be inserted into the first positioning hole and the second positioning hole to limit the rotation angle of the rotating rod.

[0016] Preferably, the height of the locating pin is greater than the height of the latch.

[0017] Preferably, the bottom of the connecting plate is fixed with an insertion tube, and the bearing platform is provided with an installation hole adapted to the insertion tube.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] In this invention, the positioning pin and the first and second positioning holes effectively limit the rotation rod, preventing it from rotating arbitrarily during the lifting and lowering of the ink pad, thus improving the overall structural stability. Furthermore, the height of the positioning pin is greater than the height of the insertion pin, preventing the positioning pin from interfering with the normal use of the insertion pin and ensuring smooth installation and removal of the ink pad.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example

[0031] Please see Figures 1-6 This utility model provides the following technical solution: an automatic lifting ink stack for a 3D printer, including a support platform 1.

[0032] A fixing plate 2 is provided on the top of the supporting platform 1;

[0033] An ink pad 3 is provided on the fixed plate 2;

[0034] Two sets of limiting components 100 are provided on the top two sides of the bearing platform 1 for the installation and fixing of the ink pad 3. The limiting components 100 include connecting plates 110 fixed on both sides of the ink pad 3, and each of the two connecting plates 110 is provided with a pair of limiting holes 111.

[0035] A rotating rod 101 is provided through the bearing platform 1. One end of the rotating rod 101 is fixed with a fixing member 102. The bottom of the fixing member 102 is provided with a pair of pins 103 that are adapted to the limiting hole 111.

[0036] A washer 104 and a spring 105 are sequentially fitted onto the outer wall of the rotating rod 101. The two ends of the spring 105 abut against the washer 104 and the bottom of the support platform 1, respectively. In use, the support platform 1 can be installed at a designated position on the 3D printer. When the ink pad 3 needs to be installed, the rotating rod 101 can be rotated to both sides to adjust the angle of the fixing member 102, preventing the fixing member 102 from obstructing the ink pad 3. The ink pad 3 can then be placed on the fixing plate 2. Then, the fixing member 102 is pulled upwards and the rotating rod 101 is rotated, causing the spring 105 to be compressed by the washer 104. While rotating the rotating rod 101, the pin 103 can be adjusted to its limit. Above the positioning hole 111, the fixing member 102 is then released. Under the elastic force of the spring 105, the pin 103 will be inserted into the limiting hole 111, thereby completing the installation and fixing of the ink pad 3. When the ink pad 3 needs to be replaced, simply rotate the rotating rod 101 again to pull the pin 103 out of the limiting hole 111, and the ink pad 3 can be easily removed. The replacement process is simple and quick, without the need to disassemble too many parts, which greatly improves maintenance efficiency. In addition, due to the cooperation between the pin 103 and the limiting hole 111, as well as the elastic force of the spring 105, the ink pad 3 is not easy to shift during the lifting and lowering process, ensuring the accuracy threshold required for the inkjet head sealing.

[0037] Preferably, by Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, the end of the rotating rod 101 away from the fixing member 102 is provided with a threaded section and is locked by a nut 106; the washer 104 and the spring 105 can be sleeved on the rotating rod 101, and finally the nut 106 is tightened on the threaded section of the rotating rod 101, so as to limit the washer 104 and the spring 105 by the nut 106, so as to facilitate the installation and removal of the limiting component 100.

[0038] Preferably, by Figure 2 , Figure 4 and Figure 5As shown, in this embodiment, the support platform 1 has a pair of storage holes 112 corresponding to the position of the pin 103. After removing the ink pad 3, the pin 103 can be rotated to the top of the storage hole 112, and then the fixing member 102 can be pressed down to insert the pin 103 into the storage hole 112, so as to prevent the fixing member 102 from rotating randomly.

[0039] Preferably, by Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, a positioning pin 107 is fixed on the fixing member 102, and a first positioning hole 108 and a second positioning hole 109 are provided on the bearing platform 1. The positioning pin 107 can be inserted into the first positioning hole 108 and the second positioning hole 109 to limit the rotation angle of the rotating rod 101. The cooperation between the positioning pin 107 and the first positioning hole 108 can increase the limiting effect on the rotating rod 101, so as to prevent the rotating rod 101 from rotating arbitrarily when raising and lowering the ink pad 3, thereby improving the stability of the overall structure. When it is necessary to rotate the rotating rod 101, simply pull the positioning pin 107 out of the first positioning hole 108 and rotate it above the second positioning hole 109 so that the positioning pin 107 is inserted into the interior of the second positioning hole 109, so that the pin 103 and the positioning pin 107 can be inserted into the limiting hole 111 and the receiving hole 112 respectively, so as to facilitate the installation and removal of the ink pad 3.

[0040] Preferably, by Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, the height of the positioning pin 107 is greater than the height of the insertion pin 103; this avoids the positioning pin 107 from affecting the normal use of the insertion pin 103, and ensures the smooth installation and removal process of the ink pad 3.

[0041] Preferably, by Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, the bottom of the connecting plate 110 is fixed with a tube 5, and the bearing platform 1 is provided with an installation hole 4 that is compatible with the tube 5. When placing the ink pad 3, the tube 5 can be inserted into the installation hole 4. Through the cooperation of the tube 5 and the installation hole 4, the ink pad 3 can be initially limited to facilitate subsequent operations.

[0042] Components not described in detail in this article are existing technologies.

[0043] The working principle and usage process of this utility model: the rotating rod 101 is in the initial locked position, the positioning pin 107 is inserted into the first positioning hole 108, the pin 103 of the fixing member 102 is facing away from the ink pad 3 installation area, and the spring 105 is in a naturally extended state.

[0044] Pull the fixing member 102 upward, the spring 105 is compressed by the washer 104, and at the same time rotate the rotating rod 101 counterclockwise, so that the pin 103 rotates to above the storage hole 112. At this time, the fixing member 102 no longer blocks the installation path of the ink pad 3.

[0045] Place the ink pad 3 on the fixing plate 2, and insert the tube 5 at the bottom of the connecting plate 110 into the mounting hole 4 of the bearing platform 1 to complete the initial positioning of the ink pad 3 and prevent it from shifting during installation.

[0046] Pull the fixing member 102 upward again, rotate the rotating rod 101 to align the pin 103 with the limiting hole 111 of the connecting plate 110, release the fixing member 102, the spring 105 returns to its original position and pushes the fixing member 102 downward, the pin 103 is inserted into the limiting hole 111, and at the same time the positioning pin 107 automatically falls into the first positioning hole 108, completing the locking of the ink pad 3. At this time, the elasticity of the spring 105 ensures that the pin 103 and the limiting hole 111 are tightly engaged, preventing the ink pad 3 from shaking during the lifting and lowering process;

[0047] Pull the fixing piece 102 upward to compress the spring 105, and at the same time pull the positioning pin 107 out of the first positioning hole 108. Rotate the rotating rod 101 clockwise to make the pin 103 disengage from the limiting hole 111 and rotate it to above the storage hole 112.

[0048] After the pin 103 is completely disengaged from the limiting hole 111, the ink pad 3 can be lifted directly upwards, and the insertion tube 5 of the connecting plate 110 can be pulled out from the mounting hole 4, thus completing the disassembly of the ink pad 3. The whole process does not require tools.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
