Description

Technical Field

[0001] This utility model relates to the field of laser printer technology, and in particular to a laser printer mounting platform. Background Technology

[0002] Laser printers are non-impact printing devices that combine laser imaging technology with electrophotographic principles. Laser printers use a computer-controlled laser beam to form an electrostatic latent image on the surface of a photosensitive drum. Then, using toner adsorption and thermal fixing technology, the image is transferred to paper. Laser printers are often fixed in a mounting table, which has a positioning grid on the top.

[0003] A search revealed a utility model patent with publication number CN205202472U, which discloses a laser printer for processing leather. It includes a main frame, a secondary frame, a worktable, and a galvanometer device. The secondary frame is horizontally positioned at the bottom of the main frame, and the galvanometer device is mounted on the top of the main frame. The worktable is mounted on the secondary frame and can move relative to it. A position sensor is also installed on the main frame to detect whether the worktable's working area is fully inside the main frame. The printer features a simple structure, allows for continuous production, and offers high production efficiency. By incorporating the position sensor, the movement of the worktable can be precisely controlled, preventing the leather from being partially inserted into the processing area.

[0004] In the aforementioned structure, since the grid coordinate lines are directly printed on the worktable surface, long-term friction will cause the grid to wear down, resulting in inaccurate positioning. Frequent calibration is required, and replacement is difficult, leading to long downtime and significantly increased subsequent maintenance costs. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a laser printer mounting platform.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a laser printer mounting table, comprising a mounting frame and a positioning grid plate, wherein a mounting plate is fixed in the middle of the mounting frame, and the inner wall of the mounting plate is provided with a limiting module, a fixing module and an auxiliary module; the positioning grid plate is slidably connected to the inner wall of the mounting plate through the limiting module, the positioning grid plate is fixed to the inner wall of the mounting plate through the fixing module, and the mounting plate is detached from the positioning grid plate through the auxiliary module.

[0007] Preferably, the limiting module includes a wing plate, one end of which is fixed to the side of the positioning grid plate, and a rectangular groove is provided on the inner wall of the mounting plate, the inner wall of which is slidably connected to the surface of the wing plate.

[0008] Preferably, the limiting module further includes a triangular component. One end of the inner wall of the rectangular groove of the mounting plate is provided with a plurality of triangular grooves. The triangular component is slidably connected to the inner wall of the triangular groove. One side of the triangular component is fixed to the side of the positioning grid plate, and the bottom of the triangular component is fixed to the surface of the wing plate.

A return spring is fixed to the side of the L-shaped component away from the wing plate, and one end of the return spring is fixed to the inner wall of the mounting plate. A push rod is rotatably connected to the side of the L-shaped component away from the wing plate. The push rod is nail-shaped, and its circumference is slidably connected to the inner wall of the mounting plate. The bent part of the L-shaped component is in contact with the surface of the wing plate.

[0010] Preferably, the L-shaped part is covered with a rubber layer at the bend, and the thickness of the rubber layer is not less than 0.2 mm.

[0011] Preferably, an inclined piece is fixed to the end of the wing plate away from the L-shaped piece, and an inclined surface is provided at the end of the inclined piece away from the wing plate. The inclined surface is sloping downwards, and a shovel-shaped inclined surface is provided at the inclined surface of the inclined piece.

[0014] Beneficial effects:

[0015] 1. This utility model enables the positioning grid plate to slide within the mounting plate via a limiting module, allowing for quick disassembly. The fixing module allows for convenient fixing and unfixing of the mounting plate when it needs to be replaced. Simultaneously, when the fixing module is unfixed, the auxiliary module causes the wing plate to pop out from the inner wall of the mounting plate, facilitating operator operation. No calibration is required when the grid is worn, allowing for quick replacement. This improves the efficiency of positioning grid plate replacement and reduces downtime.

[0016] 2. This utility model achieves the goal of keeping the positioning grid plate parallel within the mounting plate by means of the wing plate and the rectangular groove, and improves the fixing effect of the positioning grid plate and the wing plate by means of the triangular parts, thereby increasing the strength of the positioning grid plate and the wing plate. Even when the positioning grid plate and the wing plate are long, they can still be kept parallel to each other and prevent them from tilting. This achieves the effect of improving the stability of the positioning grid plate and the wing plate, preventing abnormal wear, and increasing their service life.

[0017] 3. This utility model increases the contact area between the inclined part and the dust in the rectangular groove by using the inclined surface of the shovel and the V-shaped shovel. The dust is then shoveled away by the inclined surface and finally pushed away by the through groove, preventing paper scraps and toner from mixing and clogging the rectangular groove due to paper friction, thereby improving the user experience and reducing the maintenance time in the later stage.

[0033] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0034] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0036] Reference Figures 1-6 A laser printer mounting table includes a mounting frame 1 and a positioning grid plate 101. A mounting plate 2 is fixed to the center of the mounting frame 1. The inner wall of the mounting plate 2 is provided with a limiting module, a fixing module, and an auxiliary module. The positioning grid plate 101 is slidably connected to the inner wall of the mounting plate 2 via the limiting module. The positioning grid plate 101 is fixed to the inner wall of the mounting plate 2 via the fixing module. The mounting plate 2 is detached from the positioning grid plate 101 via the auxiliary module. The limiting module of the mounting plate 2 allows the positioning grid plate 101 to slide within the mounting plate 2, enabling quick disassembly. The fixing module allows for convenient fixing and removal of the mounting plate 2 when it needs to be replaced. Simultaneously, when the fixing module is removed, the auxiliary module causes a wing plate 3 to pop out from the inner wall of the mounting plate 2, facilitating operator operation. No calibration is required when the grid is worn, allowing for quick replacement, thus improving the replacement efficiency of the positioning grid plate 101 and reducing downtime.

[0037] The limiting module includes a wing plate 3, one end of which is fixed to the side of the positioning grid plate 101. A rectangular groove is formed on the inner wall of the mounting plate 2, and the inner wall of the rectangular groove is slidably connected to the surface of the wing plate 3. The limiting module also includes a triangular member 4. Multiple triangular grooves are formed on one end of the inner wall of the rectangular groove of the mounting plate 2, and the triangular member 4 is slidably connected to the inner wall of the triangular groove. One side of the triangular member 4 is fixed to the side of the positioning grid plate 101, and the bottom of the triangular member 4 is fixed to the surface of the wing plate 3. The wing plate 3 and the rectangular groove ensure that the positioning grid plate 101 remains parallel in the mounting plate 2. The triangular member 4 improves the fixing effect between the positioning grid plate 101 and the wing plate 3, and also improves the strength of the positioning grid plate 101 and the wing plate 3. Even when the positioning grid plate 101 and the wing plate 3 are long, the parallelism between the positioning grid plate 101 and the wing plate 3 can be maintained, preventing them from tilting.

[0038] The fixing module includes an L-shaped component 6, which is rotatably connected to the inner wall of the mounting plate 2 via a pivot. A return spring 601 is fixed to the side of the L-shaped component 6 away from the wing plate 3, with one end of the return spring 601 fixed to the inner wall of the mounting plate 2. A push rod 602 is rotatably connected to the side of the L-shaped component 6 away from the wing plate 3. The push rod 602 is nail-shaped, and its circumference is slidably connected to the inner wall of the mounting plate 2. The bent part of the L-shaped component 6 is in contact with the surface of the wing plate 3. Because the end of the L-shaped component 6 away from the push rod 602 is set as an angled end, and one end of the wing plate 3 is also set as an angled end, when the mounting plate 2 contacts the wing plate 3, the L-shaped component 6 is pressed to one side, causing the L-shaped component 6 to rotate clockwise via the pivot, while simultaneously compressing the return spring. Spring 601 allows it to accumulate elastic potential energy. When the wing plate 3 has completely passed through, the L-shaped part 6 loses its obstruction and the spring 601 releases its elastic potential, causing the L-shaped part 6 to rotate counterclockwise by the pivot, thereby resetting the L-shaped part 6. This allows the L-shaped part 6 to lock onto the wing plate 3, preventing the wing plate 3 and the positioning grid plate 101 from leaving the mounting plate 2, making it easier for workers to install the positioning grid plate 101. When workers need to replace or remove the positioning grid plate 101, they press the push rod 602 to squeeze one end of the L-shaped part 6, causing the L-shaped part 6 to rotate clockwise again and leave one end of the wing plate 3. This allows workers to easily remove the wing plate 3 and the positioning grid plate 101, improving user experience and increasing work efficiency.

[0039] The L-shaped part 6 is covered with a rubber layer at the bend, and the thickness of the rubber layer is not less than 0.2 mm. Since the L-shaped part 6 is subjected to a large impact force when it is reset by the return spring 601, the rubber layer prevents the L-shaped part 6 from having a hard collision when it comes into contact with the wing plate 3, thereby improving the service life of both.

[0040] An inclined piece 5 is fixed to the end of the wing plate 3 away from the L-shaped piece 6. The inclined piece 5 has an inclined surface at the end away from the wing plate 3, with the inclined surface pointing downwards. A shovel inclined surface 501 is provided on the inclined surface of the inclined piece 5. The shovel inclined surface 501 is V-shaped. A through groove 502 is provided at the bottom of the inner wall of the rectangular groove at the end away from the L-shaped piece 6. The inclined surface of the shovel inclined surface 501 and the V-shaped shovel inclined surface 501 increase the contact area between the inclined piece 5 and the dust in the rectangular groove. The dust is shoveled by the inclined surface and finally pushed away by the through groove 502, preventing paper scraps and toner from mixing and clogging the rectangular groove due to paper friction.

[0041] The auxiliary module includes a slider 701, a pressure plate 702 fixed to one side of the slider 701, and an auxiliary spring 703 fixed to the side of the pressure plate 702 near the slider 701. One end of the auxiliary spring 703 is fixed to the inner wall of the mounting plate 2. The inner wall of the mounting plate 2 near the through groove 502 is provided with a sliding groove 7. The inner wall of the sliding groove 7 is slidably connected to the slider 701. When the pressure plate 702 contacts the inclined piece 5 of the wing plate 3, the auxiliary spring 703 accumulates elastic potential energy. When the wing plate 3 is no longer restricted by the L-shaped piece 6, the auxiliary spring 703 releases the elastic potential energy to push the wing plate 3 out of the positioning grid plate 101, thereby facilitating disassembly by the staff and improving the user experience.

[0042] A reinforcing rib 8 is fixed to the top of the slider 701. One end of the reinforcing rib 8 is fixed to one side of the pressure plate 702. The reinforcing rib 8 prevents the fixing point between the pressure plate 702 and the slider 701 from tilting, thereby improving the service life of the component. Specific Implementation Example 2:

[0044] Reference Figures 1-6 Staff members used the structure disclosed in this utility model in a printing factory. In March, due to high-frequency use, the laser printer positioning grid 101 grid wore out by 0.5mm, resulting in a ±1.2mm registration deviation when printing ID photos.

[0045] Maintenance personnel activate the device. The mounting frame 1 is welded from Q235 steel plate. The inner rectangular groove of the mounting plate 2 is 12.8mm wide. The wing plate 3 (SPCC cold-rolled steel, 2.0mm thick) is laser-welded to the positioning grid plate 101 (304 stainless steel, 0.8mm thick). During replacement, press the push rod 602 (6mm diameter). The rubber layer (Shore hardness 70) of the L-shaped part 6 detaches from the wing plate 3. The auxiliary spring 703 (1.2mm wire diameter, 5mm preload stroke) pushes the pressure plate 702, which pushes out the positioning grid plate 101 through the V-shaped shovel inclined surface 501 of the inclined part 5. The entire process takes 3 seconds. When the new positioning grid plate 101 is installed, the wing plate 3 slides in along the rectangular groove, and the 55° inclined surface of the inclined piece 5 removes the toner clumps in the groove (measured removal rate 92%), and the through groove 502 (3mm wide) discharges the debris; when the wing plate 3 contacts the L-shaped piece 6, its inclined surface compresses the return spring 601 (elastic coefficient 8N / mm), causing the L-shaped piece 6 to rotate 12°. After the triangular piece 4 (with 35% enhanced bending stiffness) slides into the triangular groove, the L-shaped piece 6 locks back. After replacement, the printing test page registration error is ≤0.1mm, and the maintenance time is reduced from the traditional 45 minutes to 3 minutes. After six months of continuous use, the rectangular groove is not clogged, and the replacement frequency of the positioning grid plate 101 is reduced from 1.8 times per month to 0.2 times per month.

[0046] The working principle of this utility model is as follows: the positioning grid plate 101 is slidably installed by embedding the wing plate 3 into the rectangular groove of the mounting plate 2. The triangular piece 4 enhances the bending strength of the positioning plate. When the wing plate 3 slides to the position of the L-shaped piece 6, its inclined surface presses the L-shaped piece 6 to rotate clockwise and compress the return spring 601. After the wing plate 3 has completely passed, the return spring 601 releases its elastic force to drive the L-shaped piece 6 to rotate counterclockwise and lock the wing plate 3 to achieve mechanical locking. The rubber layer buffers the collision.

[0047] When the staff needs to replace the worn positioning grid plate 101, press the nail-shaped push rod 602 to force the L-shaped piece 6 to disengage from the wing plate 3. At the same time, the auxiliary spring 703 pushes the pressure plate 702 through the inclined piece 5 to push out the wing plate 3 and the positioning grid plate 101, so that the positioning grid plate 101 pops out automatically.

[0048] During installation, the V-shaped shovel 501 of the inclined piece 5 moves with the wing plate 3 to scrape away the paper scraps and toner mixture in the rectangular groove, and discharges it through the through groove 502 to prevent blockage.
