Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive wheel hub parts production technology, specifically relating to a screen printing device for automotive wheel hub parts production. Background Technology
[0002] The wheel hub is the part of the car where the axle is mounted at the center of the wheel. It consists of multiple components, including the rim, offset, bead seat, flange, spokes, valve bore, and groove base. These components together form the overall structure of the wheel hub. During the production of injection-molded parts such as wheel hub components, screen printing equipment is used to print patterns, text, and other information onto the surface of the wheel hub components to enhance product recognition and added value.
[0003] Patent CN215360419U discloses "a screen printing device for injection molded parts, relating to the field of screen printing equipment technology, including a frame, a screen frame mounted on the frame, and a printing frame slidably mounted on the frame; an irregularly shaped rotating shaft is also rotatably mounted on the frame, a material tray is slidably mounted on the rotating shaft, and several positioning molds are mounted on the material tray. The positioning molds have through holes for mounting injection molded parts, and the upper edges of the mold holes are chamfered. This utility model provides a convenient and efficient screen printing device for injection molded parts."
[0004] Although the existing technology can screen print injection molded parts, the height of components such as the squeegee needs to be adjusted back and forth during the screen printing process. For example, during screen printing, the squeegee needs to be driven to move to the right to apply ink to the surface of the injection molded part through the screen. Then, the squeegee needs to be raised to move to the right of the ink to the ink to the right and then lowered to push the ink to the left and push the ink back to its original position so that the next injection molded part can be screen printed. However, raising and lowering the squeegee back and forth during the screen printing process will delay the screen printing time of the injection molded part and reduce the efficiency of screen printing. Therefore, it needs to be improved. Utility Model Content
[0005] The purpose of this invention is to provide a screen printing device for the production of automotive wheel hub parts in order to solve the above-mentioned problems.
[0006] This utility model achieves the above objectives through the following technical solutions:
[0007] A screen printing device for the production of automotive wheel hub parts includes a base plate, a fixed frame mounted on the top of the base plate, a screen plate fixedly disposed within the fixed frame, a telescopic mechanism mounted on the top of the base plate for driving the fixed frame to rise and fall, and an ink brushing mechanism mounted on the top of the fixed frame. The ink brushing mechanism includes a movable seat slidably disposed on the top of the fixed frame, two scrapers fixedly disposed on both sides of the bottom of the movable seat and cooperating to abut against the top of the screen plate, and two sealing plates fixedly disposed between the two ends of the two scrapers.
[0008] An ink cavity is formed in the gap between the bottom of the fixed frame, the two scrapers and the two sealing plates. An inkjet tube for replenishing ink into the ink cavity is fixed inside the movable seat. A drive mechanism for moving the movable seat is provided at the top of the fixed frame.
[0009] As a further optimization of this utility model, the telescopic mechanism includes two sets of multi-stage electric push rods fixedly disposed on both sides of the top of the base plate, and the fixed frame is fixedly connected between the top ends of the two sets of multi-stage electric push rods.
[0010] As a further optimization of this utility model, the driving mechanism includes a fixed frame fixedly disposed on one side of the top of the fixed frame, a threaded rod threaded in the fixed frame, and a motor fixedly installed on the outside of the fixed frame for driving the threaded rod to rotate. One end of the movable seat is movably connected in the corresponding fixed frame, and the movable seat is threadedly connected to the outer wall of the threaded rod.
[0011] As a further optimization of this utility model, the movable seat is provided with an observation hole for the user to observe the ink condition in the ink chamber, and a sealing block is movably provided in the observation hole of the movable seat.
[0012] As a further optimization of this utility model, two sets of tension springs are fixedly provided between the top of the observation hole of the movable seat and the outer wall of the sealing block.
[0013] As a further optimization of this utility model, one end of the fixed frame is fixedly provided with an ink discharge notch, and the top of the base plate is fixedly provided with an ink collection box located directly below the ink discharge notch.
[0014] The beneficial effects of this utility model are as follows:
[0015] 1. The ink cavity formed by the gap between the scraper, sealing plate, and movable seat can hold ink. After the drive mechanism moves the movable seat, the scraper can push the ink clump in the ink cavity laterally, thereby coating the ink onto injection molded parts such as automotive wheel hub parts through the screen printing plate. After the movable seat moves in the opposite direction, it can push the ink clump in the ink cavity back to its original position. This eliminates the need to raise and lower the scraper and other components on the screen printing plate during the screen printing process, thereby shortening the screen printing time and improving the efficiency of screen printing.
[0016] 2. The ink in the ink chamber can be discharged through the ink discharge notch. The discharged ink can be collected by the ink collection box. The ink can be replenished into the ink chamber by the inkjet tube, which makes it easy to replace the ink. The user can pull up the sealing block to check the remaining ink in the ink chamber through the observation hole. After releasing the sealing block, the sealing block will quickly seal the observation hole under the tension of the spring, making the operation convenient. Attached Figure Description

Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0023] Example
[0024] like Figure 1-4 As shown, a screen printing device for the production of automotive wheel hub parts includes a base plate 1, a fixed frame 2, a screen 21, a telescopic mechanism, and an ink brushing mechanism. The base plate 1 can be installed on an external workbench. The fixed frame 2 is installed on the top of the base plate 1. The screen 21 is fixedly installed inside the fixed frame 2. A through hole is provided inside the fixed frame 2, wherein the screen 21 is fixedly connected inside the through hole of the fixed frame 2, and the screen 21 is flush with the top surface of the fixed frame 2.
[0025] like Figure 1-3 As shown, the telescopic mechanism is installed on the top of the base plate 1 and is used to drive the fixed frame 2 to rise and fall. The telescopic mechanism includes two sets of multi-stage electric push rods 11 fixedly installed on both sides of the top of the base plate 1. The fixed frame 2 is fixedly connected between the top ends of the two sets of multi-stage electric push rods 11. In use, injection molded parts such as car wheel hub parts can be placed on the top of the base plate 1 and the injection molded parts such as car wheel hub parts are located below the screen plate 21. Then, controlling the telescopic extension and retraction of the multi-stage electric push rods 11 can drive the fixed frame 2 and the screen plate 21 to rise and fall. After the screen plate 21 is lowered, it can abut against the top of the injection molded parts. Since the screen plate 21 and other components can be raised and lowered, the device can screen print on injection molded parts such as car wheel hub parts of different sizes and specifications.
[0026] like Figure 1 , Figure 3 and Figure 4 As shown, the ink-brushing mechanism is installed on the top of the fixed frame 2. The ink-brushing mechanism includes a movable seat 3 that is slidably mounted on the top of the fixed frame 2, two scrapers 31 that are fixed on both sides of the bottom of the movable seat 3 and abut against the top of the filament plate 21, and two sealing plates 32 that are fixed between the two ends of the two scrapers 31. An ink cavity is formed in the gap between the bottom of the fixed frame 2, the two scrapers 31 and the two sealing plates 32. An ink jet tube 33 for replenishing ink into the ink cavity is fixedly installed inside the movable seat 3. A drive mechanism for driving the movable seat 3 to move is provided on the top of the fixed frame 2. The two sealing plates 32 are fixedly connected to both sides of the bottom of the movable seat 3. The ink jet tube 33 is connected to an external ink supply device. The external ink supply device is a publicly available technology and will not be described in detail here.
[0027] The ink cavity formed by the gap between the scraper 31, the sealing plate 32 and the movable seat 3 can hold ink. After the drive mechanism drives the movable seat 3 to move laterally, the scraper 31 can be used to push the ink clump in the ink cavity laterally, so that the ink can be coated on the injection molded parts such as automobile wheel hub parts through the screen plate 21 to complete the screen printing process of the injection molded parts.
[0028] like Figure 1-3 As shown, the drive mechanism includes a fixed frame 4 fixedly mounted on one side of the top of the fixed frame 2, a threaded rod 41 threaded inside the fixed frame 4, and a motor 42 fixedly mounted on the outside of the fixed frame 4 for driving the threaded rod 41 to rotate. One end of the movable seat 3 is movably connected to the corresponding fixed frame 4. The movable seat 3 is threadedly connected to the outer wall of the threaded rod 41. The output end of the motor 42 is fixedly connected to one end of the threaded rod 41. The fixed frame 4 can limit the internally corresponding movable seat 3, so that the movable seat 3 can move laterally within the fixed frame 4.
[0029] After the motor 42 is running, it will drive the threaded rod 41 to rotate. With the limit of the fixed frame 4, it can drive the movable seat 3 and scraper 31 and other components to move laterally. The motor 42 is an existing servo motor that can rotate forward and reverse. The multi-stage electric push rod 11 and the motor 42 are both common existing equipment. Their specific models can be selected according to actual needs, which will not be elaborated here.
[0030] like Figure 1 , Figure 3 and Figure 4As shown, the movable seat 3 has an observation hole 34 for the user to observe the ink in the ink chamber. A sealing block 35 is movably installed in the observation hole 34 of the movable seat 3. Two sets of tension springs 36 are fixed between the top of the observation hole 34 of the movable seat 3 and the outer wall of the sealing block 35. The tension springs 36 can connect the sealing block 35 and the movable seat 3. The sealing block 35 has a T-shaped longitudinal section. A handle is fixed on the top of the sealing block 35. The user can pull up the sealing block 35 by the handle and then check the remaining ink in the ink chamber through the observation hole 34. After the sealing block 35 is released, the sealing block 35 will quickly seal the observation hole 34 under the tension of the tension spring 36, so that the ink in the ink chamber is not easy to evaporate through the observation hole 34.
[0031] like Figure 1-3 As shown, a discharging ink notch 22 is fixedly provided at one end of the fixed frame 2, and an ink collection box 12 located directly below the discharging ink notch 22 is fixedly provided on the top of the base plate 1. After the movable seat 3 and other components move laterally, the remaining ink clumps on the filament plate 21 can be pushed into the discharging ink notch 22 inside the fixed frame 2. The ink clumps will flow from the discharging ink notch 22 into the ink collection box 12, thereby discharging the ink in the ink chamber. The discharged ink can be collected by the ink collection box 12, and then another type of ink can be added to the ink chamber using the inkjet tube 33, thus facilitating the replacement of ink.
[0032] It should be noted that, when using this screen printing device for the production of automotive wheel hub parts, the automotive wheel hub parts and other injection molded parts are first placed on the top of the base plate 1, and the automotive wheel hub parts and other injection molded parts are located below the screen plate 21. Then, the extension and retraction of the multi-stage electric push rod 11 can drive the fixed frame 2 and the screen plate 21 to move up and down. After the screen plate 21 is lowered, it can press against the top of the injection molded parts.
[0033] Then, the motor 42 is turned on. After the motor 42 runs, it will drive the threaded rod 41 to rotate. With the limit of the fixed frame 4, it can drive the movable seat 3 and the scraper 31 and other components to move laterally. Since the ink cavity formed by the gap between the scraper 31, the sealing plate 32 and the movable seat 3 can hold ink, after the movable seat 3 moves laterally, the scraper 31 can push the ink clump in the ink cavity laterally, so that the ink can be coated on the injection molded parts such as car wheel hub parts through the screen plate 21. After the movable seat 3 moves in the opposite direction, it can push the ink clump in the ink cavity back to its original position, so that the scraper 31 and other components on the screen plate 21 do not need to be raised and lowered back and forth during the screen printing process, thereby shortening the screen printing time and improving the efficiency of screen printing.
[0034] When the ink needs to be replaced, the movable seat 3 and other components can be moved laterally to push the remaining ink clumps on the filament 21 into the ink discharge notch 22 in the fixed frame 2. The ink clumps will flow from the ink discharge notch 22 into the ink collection box 12, thereby discharging the ink in the ink chamber. The discharged ink can be collected by the ink collection box 12, and then another type of ink can be added to the ink chamber using the inkjet tube 33, thereby replacing the ink.
[0035] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
