Description

Technical Field

[0001] The utility model relates to the technical field of 3D printers, and in particular to a material box fixing device for a light-curing 3D printer. Background Art

[0002] There are many molding technologies used in 3D printers, such as stereolithography (SLA), fused deposition modeling (FDM) and selective laser sintering (SLS). Among them, SLA enjoys a high reputation in the field of 3D printing due to its high molding precision. SLA technology mainly uses a laser with a specific intensity to focus on the surface of the photocurable material (mainly resin), so that it can complete the printing work on a layer from point to line and from line to surface. After one layer is completed, the next layer will be carried out, and it will be repeated in sequence until the final product is completed.

[0003] The photocurable resin used as the printing material has certain toxicity and needs to be sealed. Therefore, the photocurable resin needs to be placed in a sealed material box. Since the amount of resin that can be held in the material box is limited, after the resin is used up, the material box needs to be removed and replaced with a new one.

[0004] Application No. CN202022826354.5 discloses a photocuring 3D printer material box fixing device, including a 3D printer cover and a material box. The material box is arranged on the 3D printer cover. The overall locking process is convenient and efficient. It only needs to connect the clamping component with the limit piece. At this time, the clamping component is clamped relative to the limit piece. Since a clamping component is provided on opposite sides of the material box, when the clamping component is clamped relative to the limit piece on the 3D printer cover, the material box can be fixed on the 3D printer cover. The whole process does not require repeated removal of screws, thereby avoiding the possibility of screw loss.

[0005] In actual use, it was found that when disassembling and replacing the material box, the fingers need to continuously press the buckle handle so that the first connection part drives the elastic part to compress, driving the slot on the second connection part of the buckle handle to separate from the screw of the fixing screw. Because the fingers need to keep pressing the buckle handle, the buckle handle resets after releasing the fingers, and the material box is immediately fixed on the cover of the 3D printer, which requires two people to cooperate when replacing the material box, which is very inconvenient.

[0006] To this end, we propose a light-curing 3D printer material box fixing device. Utility Model Content

[0007] The main purpose of the utility model is to provide a light-curing 3D printer material box fixing device, which facilitates the replacement of the material box body through the provided rotating clamping assembly, side frame and magnetic suction block. When performing the replacement operation, it is not necessary to have multiple people cooperate to replace the material box body due to continuous pressing of fingers, which can effectively solve the problems in the background technology.

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0009] A material box fixing device for a light-curing 3D printer, comprising a printer cover and a positioning strip bonded and fixed to the surface of the printer cover, wherein the inner periphery of the positioning strip is configured with a positioning notch, a material box body is bonded to the surface of the printer cover, the outer periphery of the material box body is bonded to the inner periphery of the positioning strip, and a positioning block adapted to the positioning notch is fixed to the side wall of the material box body;

[0010] The side wall of the positioning block is structured with a side clamping groove, and a rotating clamping assembly is arranged in the side clamping groove;

[0011] The inner periphery of the positioning strip is structured with a receiving groove which is in communication with the positioning notch, the outer periphery of the positioning strip is fitted and fixed with a side frame, and the inner periphery of the side frame is slidably provided with a magnetic attraction block.

[0012] Preferably, the rotating clamping assembly includes a round rod horizontally arranged and inserted in the side clamping groove and an iron sheet rotatably arranged on the outer circumference of the round rod, and a torsion spring sleeved on the outer circumference of the round rod is arranged between the side wall of the iron sheet and the side clamping groove.

[0013] Preferably, a handle is bonded to the side wall of the magnetic block, and the cross-section of the handle is U-shaped.

[0014] Preferably, the side wall of the positioning block is configured with an inclined surface, and the inclined surface is symmetrically arranged with respect to the side clamping groove.

[0015] Preferably, the outer wall of the positioning strip is configured with a rectangular groove, and the end of the magnetic block extends into the rectangular groove.

[0016] Preferably, a symmetrically arranged sealing cover plate is rotatably provided on the top of the material box body through a hinge, and the edge sides of the sealing cover plate are in contact with each other.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] 1. The light-curing 3D printer material box fixing device can attract the iron sheet to deflect to one side of the magnetic block through the magnetic force of the magnetic block, and when the iron sheet deflects and enters the storage slot, the material box body is lifted up, and the top of the iron sheet is pressed against the storage slot, so the material box body cannot be removed, thereby fixing the material box body. When the material box needs to be replaced, the magnetic block is pulled out, and after the magnetic force of the magnetic block is lost, the iron sheet rotates along the outer circumference of the round rod to the side card slot under the action of the torsion spring, and the material box body can be easily lifted up at this time, without the need for continuous finger pressing and the need for multiple people to cooperate in replacing the material box body, and the material box body replacement operation is relatively simple;

[0019] 2. The light-curing 3D printer cartridge fixing device can quickly position and install the cartridge body through the positioning strip, the positioning block and the positioning notch when the cartridge body is attached to the printer cover surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1-4 As shown, a material box fixing device for a light-curing 3D printer comprises a printer cover 1 and a positioning strip 2 bonded and fixed to the surface of the printer cover 1, wherein the inner periphery of the positioning strip 2 is configured with a positioning notch, a material box body 3 is bonded to the surface of the printer cover 1, the outer periphery of the material box body 3 is bonded to the inner periphery of the positioning strip 2, and a positioning block 5 adapted to the positioning notch is fixed to the side wall of the material box body 3;

[0027] The positioning strip 2 is a closed square-shaped structure, and the positioning block 5 cooperates with the positioning notch to facilitate the rapid positioning of the material box body 3 and fit it on the inner periphery of the positioning strip 2;

[0028] The side wall of the positioning block 5 is configured with a side card slot 6, and a rotating card assembly is arranged in the side card slot 6, the rotating card assembly comprises a round rod horizontally arranged and inserted in the side card slot 6 and an iron sheet 7 rotatably arranged on the outer periphery of the round rod, and a torsion spring 8 sleeved on the outer periphery of the round rod is arranged between the side wall of the iron sheet 7 and the side card slot 6;

[0029] When the rotating clamping assembly is completely located in the side clamping groove 6, the material box body 3 can be flexibly moved up and down. When the parts in the rotating clamping assembly are deflected, the material box body 3 and the positioning strip 2 are relatively fixed at this time, and the material box body 3 cannot move;

[0030] The inner periphery of the positioning strip 2 is constructed with a receiving groove 9 which is connected with the positioning notch, the outer periphery of the positioning strip 2 is fitted and fixed with a side frame 10, the inner periphery of the side frame 10 is slidably provided with a magnetic block 11, when the magnetic block 11 approaches the rotating clamping assembly, it can attract the iron sheet 7 to rotate into the receiving groove 9 under the action of its magnetic force, so that when the material box body 3 is lifted up, the material box body 3 together with the iron sheet 7 are blocked by the receiving groove 9 and cannot move up.

[0031] Furthermore, a handle 12 is bonded to the side wall of the magnetic block 11, and the cross-section of the handle 12 is U-shaped.

[0032] The handle 12 is used to conveniently pull the magnetic block 11 horizontally, thereby changing the distance between the magnetic block 11 and the iron sheet 7 and controlling the attraction of the magnetic block 11 to the iron sheet 7 .

[0033] Furthermore, the side wall of the positioning block 5 is configured with an inclined surface, and the inclined surface is symmetrically arranged with respect to the side clamping groove 6 .

[0034] Under the action of the inclined surface, the positioning block 5 can smoothly enter the positioning notch.

[0035] Furthermore, the outer wall of the positioning bar 2 is configured with a rectangular groove, and the end of the magnetic block 11 extends into the rectangular groove.

[0036] Under the effect of the rectangular groove, the distance between the magnetic block 11 and the iron sheet 7 can be shortened, thereby enhancing the attraction of the magnetic block 11 to the iron sheet 7 .

[0037] Furthermore, a symmetrically arranged sealing cover plate 4 is rotatably provided on the top of the material box body 3 through a hinge, and the edge sides of the sealing cover plate 4 are in contact with each other.

[0038] Under the action of the sealing cover plate 4, the top of the material box body 3 is sealed to prevent the light-curing resin from polluting the air.

[0039] It should be noted that the utility model is a light-curing 3D printer material box fixing device. When a new material box body 3 needs to be replaced, the finger pinches the handle 12 to pull the magnetic block 11 away from the positioning bar 2, so that the magnetic block 11 loses its attraction to the iron sheet 7. The iron sheet 7 withdraws from the storage slot 9 under the action of the torsion spring 8 and is deflected and reset to the inside of the side slot 6. Then the material box body 3 can be easily lifted up, and the positioning block 5 of the side wall of the new material box body 3 is aligned with the positioning notch and then put down, and the magnetic block 11 is reset. Under the magnetic force of the magnetic block 11, the iron sheet 7 is attracted to deflect to the side of the storage slot 9, and the top of the iron sheet 7 is pressed in the storage slot 9. At this time, the iron sheet 7 of the material box body 3 cannot move upward with it, thereby fixing the material box body 3.
