Abstract
Description
Technical Field
[0001] This utility model relates to the field of drafting machine technology, and more specifically, to a drafting machine with multi-pen adaptive clamping. Background Technology
[0002] A sketching machine is a painting aid that helps artists quickly and accurately complete the initial sketching process. It typically holds a paintbrush and controls its movement via mechanical or electronic devices to create a preliminary sketch on the canvas according to a preset pattern or trajectory, thus improving painting efficiency and precision.
[0003] A drafting machine typically consists of a pen fixing device, a motion control mechanism, a drive system, and a control system. Its working principle involves setting drawing parameters through the control system, which then drives the motion control mechanism to move the pen fixed to the device along a preset trajectory, drawing the corresponding graphic on the canvas and completing the drafting process.
[0004] In existing technologies, some drafting machines still use traditional bolts to fix different brushes, which cannot quickly clamp and fix different brushes. The operation is cumbersome and time-consuming. First, the operation efficiency is low. Installing and changing brushes requires frequent tightening of bolts, which is time-consuming and laborious, and interrupts the creative rhythm. Second, the accuracy is difficult to guarantee. If the bolt tightness is not properly controlled, the brush will be unstable or deformed, affecting the smoothness and accuracy of the drawn lines. Third, the scope of application is limited. Different brush sizes are poorly compatible, and bolts and clamping parts need to be adjusted repeatedly, which is not very versatile. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a multi-pen adaptive clamping drafting machine to solve the problem that it is impossible to quickly clamp and fix different pens in the prior art.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a multi-pen adaptive clamping drafting machine, comprising...
[0007] A support frame has a movable block slidably connected to its inner wall, a fixed block slidably connected to the outside of the movable block, a slider fixedly connected to the outside of the fixed block, multiple pressure plates slidably connected to the inner wall of the fixed block, an elastic element fixedly connected to the outside of each of the multiple pressure plates, a connecting plate fixedly connected to the end of each pressure plate away from the elastic element, an installation groove provided on the inner wall of the fixed block, a paintbrush body detachably connected to the inner wall of the fixed block, multiple gaskets fixedly connected to the inner wall of the fixed block, a retaining ring fixedly connected to the end of the connecting plate away from the pressure plate, and an anti-slip pad fixedly connected to the end of the retaining ring away from the connecting plate.
[0008] The inner wall of the fixed block is slidably connected to a pull block, the outside of the pull block is fixedly connected to a slide plate, the outside of the slide plate is fixedly connected to an elastic element two, the outside of the pull block is provided with a groove, the end of the slide plate away from the pull block is fixedly connected to two U-shaped rings, the end of each U-shaped ring away from the slide plate is fixedly connected to a retaining pad, the outside of the pull block is fixedly connected to a support rod, the end of the support rod away from the pull block is fixedly connected to a limit plate.
[0009] The support rod is externally slidably connected to the inner wall of the fixed block, and the end of the elastic element away from the slide plate is fixedly connected to the inner wall of the fixed block.
[0010] One end of the elastic element away from the pressure plate is fixedly connected to the inner wall of the fixed block, and the outer side of the connecting plate is slidably connected to the inner wall of the fixed block.
[0011] The outer side of the slide plate is slidably connected to the inner wall of the fixed block, and the outer side of the retaining ring is slidably connected to the inner wall of the fixed block.
[0012] The end of the limiting plate away from the support rod is in contact with the outside of the brush body, and the end of the anti-slip pad away from the retaining ring is in contact with the outside of the brush body.
[0013] The outer side of the U-shaped ring is slidably connected to the inner wall of the fixed block, and the end of the pad away from the U-shaped ring is in contact with the outer side of the brush body.
[0014] The end of the pad away from the fixed block is in contact with the outside of the brush body, and the end of the slider away from the fixed block is slidably connected to the inner wall of the moving block;
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] In the above solution, after the brush body is placed inside the mounting slot in the fixed block, the elastic element is squeezed by the retaining ring and pressure plate, causing the elastic element to deform and release space and potential energy. The anti-slip pad squeezes the brush body so that the brush body is tightly attached to the outside of the pad in the fixed block, forming a clamping and fixing state. This achieves adaptive clamping and fixing of brush bodies of different thicknesses to meet production needs. The anti-slip pad and pad can increase the friction on the brush body, so that the equipment maintains a stable effect on the brush body during operation and improves the painting accuracy.
[0017] In the above solution, when installing and clamping the paintbrush body, the pull block is pulled by the groove, causing the sliding plate in the pull block to compress the elastic element two. Due to the characteristics of the elastic element two, it will deform and contract to release space, allowing the U-shaped ring to be hidden inside the fixed block. When the paintbrush body is installed and rotated, the pull block is released. At this time, the elastic element two releases potential energy, causing the U-shaped ring to move and compress the paintbrush body. At the same time, when the pull block moves, it moves to the top of the paintbrush body through the limiting plate connected by the support rod. This prevents the paintbrush body from moving upward due to the force when drawing, improves work efficiency, and facilitates the quick installation and disassembly of the paintbrush body.

[0025] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0026] As attached Figure 1 To be continued Figure 5 An embodiment of this utility model provides a multi-pen adaptive clamping drafting machine, including...
[0027] A support frame 1 has a sliding block 2 slidably connected to its inner wall, allowing it to slide on the support frame 1. A fixed block 3 is slidably connected to the outer side of the sliding block 2, allowing it to move relative to the sliding block 2. A slider 4 is fixedly connected to the outer side of the fixed block 3, providing guidance and stability during movement and ensuring smoother operation of the drafting machine. Multiple pressure plates 5 are slidably connected to the inner wall of the fixed block 3, allowing them to move within the fixed block 3 and facilitating the clamping of the brush body 9. Elastic elements 6 are fixedly connected to the outer side of each pressure plate 5, providing elastic force and allowing for adaptive adjustment based on the thickness of the brush body 9 during clamping.
[0028] A connecting plate 7 is fixedly connected to the end of the pressure plate 5 away from the elastic element 6. The connecting plate 7 connects the pressure plates 5 and serves to transmit force. An installation groove 8 is provided on the inner wall of the fixing block 3, providing a mounting position for the brush body 9, allowing the brush body 9 to be accurately placed within the fixing block 3. The brush body 9 is detachably connected to the inner wall of the fixing block 3, facilitating the replacement and installation of the brush body 9. Multiple gaskets 10 are fixedly connected to the inner wall of the fixing block 3. The gaskets 10 increase the friction between the brush body 9 and the gaskets 10, and to a certain extent protect the brush body 9 from damage. A retaining ring 11 is fixedly connected to the end of the connecting plate 7 away from the pressure plate 5. The retaining ring 11 cooperates with the pressure plate 5 and the elastic element 6 to effectively clamp and fix the brush body 9. The end of the retaining ring 11 away from the connecting plate 7 is fixedly connected to an anti-slip pad 12. The anti-slip pad 12 can increase the friction between the brush body 9 and the brush body 9, prevent the brush body 9 from sliding in the fixing block 3, and improve the fixing effect of the brush body 9.
[0029] A pull block 13 is slidably connected to the inner wall of the fixed block 3. The sliding of the pull block 13 within the inner wall of the fixed block 3 allows for the installation and removal of the paintbrush body 9. A slide plate 14 is fixedly connected to the outside of the pull block 13. The slide plate 14 can slide within the fixed block 3 and provides guidance when the pull block 13 moves. An elastic element 15 is fixedly connected to the outside of the slide plate 14. The elastic element 15 provides elastic force to the slide plate 14 and the pull block 13, allowing the pull block 13 to move and be fixed adaptively within the fixed block 3. A groove 16 is provided on the outside of the pull block 13. The groove 16 facilitates the operation of the pull block 13; pulling the groove 16 moves the pull block 13 within the fixed block 3. Two U-shaped rings 17 are fixedly connected to the end of the slide plate 14 furthest from the pull block 13. The U-shaped rings 17, driven by the pull block 13, can compress the paintbrush body 9, thus fixing the paintbrush body 9. Both U-shaped rings 17 have a retaining pad 18 fixedly connected to the end furthest from the slide plate 14. The retaining pad 18 increases the friction between the retaining pad and the brush body 9, improving the fixation effect on the brush body 9. A support rod 19 is fixedly connected to the outside of the pull block 13. The support rod 19 connects the pull block 13 and the limiting plate 20, and can drive the limiting plate 20 to move when the pull block 13 moves. The end of the support rod 19 furthest from the pull block 13 is fixedly connected to the limiting plate 20. The limiting plate 20 prevents the brush body 9 from moving upward due to force when sketching, improving work efficiency and ensuring the working accuracy of the sketching machine.
[0030] The support rod 19 is externally slidably connected to the inner wall of the fixed block 3. The sliding of the support rod 19 on the inner wall of the fixed block 3 allows the pull block 13 to drive the limiting plate 20 to move stably when it moves, and it can also provide a certain support within the fixed block 3. The end of the elastic element 15 away from the slide plate 14 is fixedly connected to the inner wall of the fixed block 3. The connection between the elastic element 15 and the inner wall of the fixed block 3 allows the elastic element 15 to deform when the slide plate 14 and the pull block 13 move, thereby achieving adaptive fixing and release of the paintbrush body 9.
[0031] The end of the elastic element 6 furthest from the pressure plate 5 is fixedly connected to the inner wall of the fixing block 3. The connection between the elastic element 6 and the inner wall of the fixing block 3 allows the elastic element 6 to deform when the pressure plate 5 moves, thereby adaptively clamping and fixing the brush body 9. The outer side of the connecting plate 7 is slidably connected to the inner wall of the fixing block 3. The sliding of the connecting plate 7 on the inner wall of the fixing block 3 allows the pressure plate 5 to move within the fixing block 3 and can transmit the force of the pressure plate 5 to the retaining ring 11.
[0032] The external sliding connection of the slide plate 14 is to the inner wall of the fixed block 3. The sliding of the slide plate 14 on the inner wall of the fixed block 3 allows the pull block 13 to move within the fixed block 3 and provides a certain guiding function during movement. The external sliding connection of the retaining ring 11 is to the inner wall of the fixed block 3. The sliding of the retaining ring 11 on the inner wall of the fixed block 3 allows the retaining ring 11 to adaptively adjust according to the thickness of the brush body 9, thereby achieving effective clamping of the brush body 9.
[0033] The end of the limiting plate 20 furthest from the support rod 19 contacts the outside of the brush body 9. This contact prevents the brush body 9 from moving upwards due to force during sketching, ensuring the working accuracy and stability of the sketching machine. The end of the anti-slip pad 12 furthest from the retaining ring 11 contacts the outside of the brush body 9. This contact increases the friction between the anti-slip pad 12 and the brush body 9, preventing the brush body 9 from sliding within the fixing block 3 and improving the fixation effect on the brush body 9.
[0034] The U-shaped ring 17 is externally slidably connected to the inner wall of the fixing block 3. The sliding of the U-shaped ring 17 on the inner wall of the fixing block 3 allows the U-shaped ring 17 to press against the brush body 9 under the action of the pull block 13, thereby fixing the brush body 9. The end of the retaining pad 18 away from the U-shaped ring 17 is in contact with the outside of the brush body 9. The contact between the retaining pad 18 and the brush body 9 increases the friction between them, improving the fixing effect of the brush body 9.
[0035] The end of the gasket 10 furthest from the fixed block 3 contacts the outside of the brush body 9. This contact increases the friction between the gasket 10 and the brush body 9, and to some extent protects the brush body 9 from damage. The end of the slider 4 furthest from the fixed block 3 is slidably connected to the inner wall of the moving block 2. The sliding of the slider 4 on the inner wall of the moving block 2 allows the fixed block 3 to move relative to the moving block 2, increasing the flexibility of the drafting machine structure.
[0036] The working process of this utility model is as follows:
[0037] First, after the brush body 9 is placed inside the mounting slot 8 of the fixing block 3, the elastic element 6 is squeezed by the retaining ring 11 and the pressure plate 5, causing the elastic element 6 to deform and release space and potential energy. The anti-slip pad 12 squeezes the brush body 9 so that the brush body 9 is tightly attached to the outside of the pad 10 in the fixing block 3, forming a clamping and fixing state. This realizes the clamping and fixing of brush bodies 9 with different thicknesses to meet production needs. The anti-slip pad 12 and the pad 10 can increase the friction on the brush body 9, so that the brush body 9 can continue to maintain a stable effect during operation, thus improving the painting accuracy.
[0038] When installing and clamping the paintbrush body 9, the pull block 13 is pulled by the groove 16, causing the slide plate 14 in the pull block 13 to squeeze the elastic element 15. Due to the characteristics of the elastic element 15, it will deform and contract to release space, allowing the U-shaped ring 17 to be hidden inside the fixing block 3. When the paintbrush body 9 is installed and rotated, the pull block 13 is released. At this time, the elastic element 15 releases potential energy, causing the U-shaped ring 17 to move and squeeze the paintbrush body 9. At the same time, when the pull block 13 moves, it moves to the top of the paintbrush body 9 through the limiting plate 20 connected by the support rod 19. This prevents the paintbrush body 9 from moving upward due to the force when drawing, improving work efficiency and facilitating the quick installation and disassembly of the paintbrush body 9.
