Description

Technical Field

[0001] This utility model relates to the field of 3D printing equipment technology, and in particular to a stencil that is easy to disassemble. Background Technology

[0002] 3D printing is a technology that uses digital model files as a basis and powdered metal or resin adhesive materials to construct objects layer by layer. 3D printing uses a photopolymer 3D printer to complete the printing process. Photopolymer rapid prototyping uses photosensitive resin as raw material. Under the control of a control system, an ultraviolet laser beam emitted by a laser scans the surface of the photosensitive resin point by point according to the cross-sectional information of each layer of the part. The thin layer of resin in the scanned area undergoes a photopolymerization reaction and solidifies, forming a thin layer of the part. After one layer is solidified, the stencil moves down a precise distance so that a new layer of liquid resin can be applied to the previously solidified resin surface. Then, the next layer is scanned and processed, and this process is repeated until the entire part is manufactured, resulting in a three-dimensional solid prototype. During the solidification process, the liquid level will change due to the solidification of the resin. To ensure that the liquid level remains relatively constant, the amount of change in the liquid level must be accurately detected using a liquid level sensor inside the photopolymer 3D printer.

[0003] A search revealed Chinese Patent Publication No. CN217752783U, which discloses a curing stencil for a photopolymer 3D printer, belonging to the field of photopolymer 3D printer technology. The invention includes a mounting frame with an annular groove on its upper surface, one side of which communicates with the interior of the frame. A printing stencil is mounted on the bottom of the groove, and a locking mechanism is provided on the inner wall of the groove to secure the stencil to the bottom. This invention offers the advantage of facilitating the installation and removal of the printing stencil by the operator. However, in actual use, while the device installs the stencil via the annular groove and locking mechanism, dirt adheres to the installation location after removal. This dirt buildup during repeated installation can affect the locking effect, leading to internal dirt accumulation and corrosion at the connection points, thus reducing the stencil's lifespan. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a mesh panel that is easy to disassemble, aiming to improve the problem in the prior art where dirt adheres to the installation position after disassembly, which affects the installation and locking effect during repeated installation, causes corrosion at the connection position, and reduces the service life of the mesh panel.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a detachable mesh plate, comprising a mounting shell and a mesh plate component. The front side of the mounting shell engages with the rear side of the mesh plate component. L-shaped plates are fixedly connected to both the upper and lower sides of the mounting shell. A cleaning shell is fixedly mounted on the front side of the L-shaped plates. A through groove is provided on one side of the cleaning shell. A return spring is fixedly connected to both the left and right ends of one side of the inner wall of the cleaning shell. A mounting plate is fixedly connected to one end of the return spring. Bolts are threadedly connected to both the left and right ends of one side of the mounting plate. A cleaning brush is threadedly connected to one end of each bolt. Locking plates are rotatably connected to both the left and right ends of the top wall of the mounting shell. Two locking grooves are provided in the middle of the top wall of the mounting shell and the middle of the top wall of the mesh plate component. The bottoms of the two locking plates engage with the corresponding locking grooves. A cooling mechanism is provided in the middle of the top wall of the mounting shell.

[0006] The above technical solution allows for the displacement of the mesh plate component when it engages with the mounting shell. The adjacent sides of the two cleaning brushes clean the installation position of the mesh plate component. At the same time, under the elastic force of multiple return springs, the mounting plate and the cleaning brush are squeezed, thereby improving the cleaning effect of the cleaning brush on the installation position of the mesh plate component. Secondly, the mesh plate component is fixed by flipping the locking plate, avoiding the accumulation of dirt at the installation position and causing corrosion at the connection position.

[0007] As a further description of the above technical solution:

[0008] The cooling mechanism includes a fixed shell, the bottom of which is fixedly connected to the middle of the top wall of the mounting shell. A threaded rod is rotatably connected to the inner bottom wall of the fixed shell, and a knob is fixedly connected to the top of the threaded rod. A sliding nozzle is threadedly connected to the outer wall of the threaded rod. A delivery pipe is connected to the left side of the sliding nozzle, and a connecting shell is connected to the bottom end of the delivery pipe. The right side of the connecting shell is fixedly connected to the left side of the mounting shell, and an adsorption sponge plate is slidably installed on the inner wall of the connecting shell.

[0009] The above technical solution involves connecting an air pump to the rear of the housing to deliver airflow. The delivered airflow is dried by an adsorption sponge plate, preventing moisture from affecting the 3D printed product. The airflow is then sprayed through a sliding nozzle, and the height of the nozzle can be changed by rotating a knob, thereby improving the cooling efficiency of the product.

[0010] As a further description of the above technical solution:

[0011] The cooling mechanism also includes a rubber ring, the inner wall of which is fixedly installed at the bottom of the outer wall of the conveying pipe, and the outer wall of which is fixedly connected to the top wall of the connecting shell.

[0012] The above technical solution enables the protection of the bottom connection of the delivery pipe through the connection of the rubber ring.

[0013] As a further description of the above technical solution:

[0014] A handle is fixedly connected to the left side of the absorbent sponge board, and a rubber sleeve is fixedly connected to the middle of the handle.

[0015] The above technical solution makes it easier to pull out the sponge board using the handle and rubber sleeve, while also improving the anti-slip effect.

[0016] As a further description of the above technical solution:

[0017] The outer wall of the knob is fixedly connected with multiple protrusions, all of which are arranged in a ring.

[0018] The above technical solution improves the static friction of the knob by using multiple protrusions.

[0019] As a further description of the above technical solution:

[0020] Each of the bolts has a rubber pad fixedly connected to its center, and all of the bolts are designed symmetrically.

[0021] The above technical solution reduces the rotational damage to the mounting plate caused by the bolts by fixing it with rubber pads.

[0022] As a further description of the above technical solution:

[0023] The top wall of the mesh panel is provided with multiple arc grooves, and the multiple arc grooves are all equally spaced.

[0024] The above technical solution utilizes multiple arc grooves to provide support for the printed product.

[0025] As a further description of the above technical solution:

[0026] The rear left and right ends of the mounting shell are fixedly connected to connecting plates, and the rear side of the connecting plates is provided with mounting grooves.

[0027] The above technical solution facilitates the fixing of the mounting shell by using a connecting plate and a mounting groove.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the displacement generated when the mesh plate is engaged with the mounting shell enables the two cleaning brushes to clean the installation position of the mesh plate. Furthermore, under the elastic force of multiple return springs, the contact force between the cleaning brushes and the mesh plate is increased, thereby improving the cleaning effect on the installation position of the mesh plate. Secondly, the mesh plate is fixed by flipping the locking plate, which avoids the accumulation of dirt at the installation position and causes corrosion at the connection position, thus improving the service life of the mesh plate connection.

[0030] 2. In this utility model, an air pump is connected to the rear side of the connecting shell to deliver airflow. The delivered airflow is dried by an adsorption sponge plate, which avoids the output airflow containing moisture from affecting the 3D printed product. Then, the airflow is sprayed through a sliding nozzle. At the same time, the height of the sliding nozzle can be changed by rotating the knob, thereby improving the cooling efficiency of the product.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0039] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a detachable mesh plate, comprising a mounting shell 1 and a mesh plate component 3. The front side of the mounting shell 1 engages with the rear side of the mesh plate component 3. L-shaped plates 4 are fixedly connected to both the upper and lower sides of the mounting shell 1. A cleaning shell 5 is fixedly mounted on the front side of the L-shaped plate 4. A through groove 6 is provided on one side of the cleaning shell 5. The cleaning shell 5 is connected and supported by the L-shaped plate 4. The through groove 6 facilitates the use of bolts 9. Return springs 7 are fixedly connected to the left and right ends of one side of the inner wall of the cleaning shell 5. One end of the return spring 7 is fixedly connected to a mounting plate 8. The left and right ends of one side of the mounting plate 8... All are threaded with bolts 9, and one end of bolt 9 is threaded with a cleaning brush 10. Under the elastic force of the return spring 7, the mounting plate 8 and the cleaning brush 10 are simultaneously subjected to pressure, thereby improving the cleaning effect. The left and right ends of the top wall of the mounting shell 1 are rotatably connected with locking plates 11. The middle of the top wall of the mounting shell 1 and the middle of the top wall of the mesh plate 3 are both provided with two locking grooves 12. The bottom of the two locking plates 11 respectively engages with the corresponding locking grooves 12. By flipping the locking plates 11, they pass through the locking grooves 12 to complete the fixed installation of the mesh plate 3. A cooling mechanism 2 is provided in the middle of the top wall of the mounting shell 1.

[0040] Specifically, by engaging the rear side of the mesh plate 3 with the interior of the mounting shell 1, the displacement of the mesh plate 3 during installation is effectively controlled. The two cleaning brushes 10 clean the installation location promptly during mesh plate 3 installation. The coordinated work of the two cleaning brushes 10 improves cleaning efficiency and effectiveness. Through the elastic force of multiple return springs 7, the mounting plate 8 and the cleaning brushes 10 fixed by bolts 9 are simultaneously compressed. This compression increases the contact area between the cleaning brushes 10 and the mesh plate 3, further enhancing the cleaning effect of the cleaning brushes 10 on the installation location of the mesh plate 3. This effectively avoids the potential corrosion risk to the installation location of the mesh plate 3 caused by residual dirt. The flipping operation of the locking plate 11 allows its bottom end to lock with the corresponding locking groove 12, simplifying the installation process of the mesh plate 3 and making installation more convenient and efficient. This ensures that the mesh plate 3 will not shift or loosen during installation, ultimately preventing the accumulation of dirt at the installation location and effectively extending the service life of the mesh plate 3 connection.

[0041] Reference Figure 1 , Figure 2 and Figure 5 The cooling mechanism 2 includes a fixed shell 201. The bottom of the fixed shell 201 is fixedly connected to the middle of the top wall of the mounting shell 1. A threaded rod 202 is rotatably connected to the inner bottom wall of the fixed shell 201. A knob 203 is fixedly connected to the top of the threaded rod 202. When the knob 203 is rotated, the threaded rod 202 rotates synchronously, causing the sliding nozzle 205 to be driven to rise and fall. The outer wall of the threaded rod 202 is threadedly connected to the sliding nozzle 205. The left side of the sliding nozzle 205 is connected to a conveying pipe 206. The bottom end of the conveying pipe 206 is connected to a connecting shell 207. An air pump is connected to the rear side of the connecting shell 207 so that the airflow output by it is dried through the adsorption sponge plate 208 and then output through the sliding nozzle 205. The right side of the connecting shell 207 is fixedly connected to the left side of the mounting shell 1. The adsorption sponge plate 208 is slidably installed on the inner wall of the connecting shell 207.

[0042] Specifically, by connecting the rear of the connecting shell 207 to an air pump, airflow can be output. The airflow is adsorbed and dried by the adsorption sponge plate 208, effectively avoiding the presence of moisture in the output airflow, which would adversely affect the molding effect of the 3D printed product. By rotating the knob 203, the threaded rod 202 drives the sliding nozzle 205 to slide inside the fixed shell 201, thereby completing the lifting action and changing the height. Finally, the dried airflow is sprayed through the sliding nozzle 205, improving the cooling efficiency of the product and ensuring the uniformity and consistency of the cooling process, thereby further improving the overall quality of the 3D printed product.

[0043] Reference Figure 1 , Figure 3 and Figure 5 The cooling mechanism 2 also includes a rubber ring 209, the inner wall of which is fixedly installed at the bottom of the outer wall of the conveying pipe 206, and the outer wall of which is fixedly connected to the top wall of the connecting shell 207; a handle 17 is fixedly connected to the left side of the adsorption sponge plate 208, and a rubber sleeve 18 is fixedly connected to the middle of the handle 17; a plurality of protrusions 204 are fixedly connected to the outer wall of the knob 203, and the plurality of protrusions 204 are arranged in a ring.

[0044] Specifically, the rubber ring 209 protects the bottom connection of the delivery pipe 206, thereby reducing wear at the connection and improving service life. The handle 17 and the rubber sleeve 18 facilitate the replacement of the adsorption sponge plate 208. The fixing of multiple protrusions 204 improves the anti-slip effect of the knob 203 and increases static friction.

[0045] Reference Figure 1 and Figure 3A rubber pad 15 is fixedly connected to the middle of each of the multiple bolts 9, and the multiple bolts 9 are all symmetrically designed; the top wall of the mesh plate 3 is provided with multiple arc grooves 16, and the multiple arc grooves 16 are all equally spaced; the left and right ends of the rear side of the mounting shell 1 are fixedly connected with connecting plates 13, and the rear side of the connecting plates 13 is provided with mounting grooves 14.

[0046] Specifically, the rubber pad 15 reduces the rotational damage to the mounting plate 8 during the rotational installation of the bolt 9, the multiple arc grooves 16 increase the contact area with the screen 3 during printing, thereby improving the cost ratio, and the connecting plate 13 and the mounting groove 14 facilitate the fixed installation of the mounting shell 1.

[0047] Working principle: Upon initial use, the rear side of the mesh plate 3 engages with the interior of the mounting housing 1, causing displacement during installation. Two cleaning brushes 10 then clean the installation location of the mesh plate 3. Subsequently, under the elastic force of multiple return springs 7, the mounting plate 8 and the cleaning brushes 10, fixed by bolts 9, are simultaneously compressed. This compression by the return springs 7 increases the contact area between the cleaning brushes 10 and the mesh plate 3, thus improving the cleaning effect on the installation location. Finally, the flipping of the locking plate 11 locks its bottom end into the corresponding locking groove 12, facilitating easy installation of the mesh plate 3. This design avoids the accumulation of dirt at the installation location, which could lead to corrosion at the connection points, thus improving the service life of the mesh plate 3 connection. Furthermore, by connecting the rear side of the connecting shell 207 to an air pump, airflow is output. The airflow is dried by the adsorption sponge plate 208, preventing the output airflow from containing moisture that could affect the molding effect of the 3D printed product. Then, by rotating the knob 203, the threaded rod 202 drives the sliding nozzle 205 to slide inside the fixed shell 201, thereby completing the lifting and lowering process and changing the height. Finally, the airflow is sprayed through the sliding nozzle 205, which improves the cooling efficiency of the product.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
