Description

Technical Field

[0001] This utility model relates to the field of colored pen production technology, specifically to a quantitative filling device for colored pens. Background Technology

[0002] Colored markers, also known as watercolor pens, are a type of drawing tool. Their advantages include rich and vibrant colors, while their disadvantages include a shorter lifespan, uneven water distribution, unnatural transitions, and difficulty in mixing two colors. Therefore, they are generally suitable for children's drawings. Some colored markers have casings divided into several vertical watercolor slots, each filled with different watercolors. This allows the marker to write large characters or draw different patterns in different colors at once, and the colors can be adjusted arbitrarily. One marker can write large characters or color large areas of calligraphy or painting in one go, and the rich color variations are more suitable for artistic creation, improving the drawing effect and helping to enhance students' learning interest and calligraphy / painting skills. In actual production, the bottom of the colored marker casing usually has a groove, which is inserted into a protrusion to fix the casing in place.

[0003] Referring to Chinese Patent Publication No. CN220662109U, with a publication date of March 26, 2024, a watercolor pen ink filling device is disclosed. This device uses a base, a fixing plate, a return spring, a limiting half-ring, and a damping half-ring to hold the ink bottle inside the base. At the same time, the return spring, the limiting half-ring, and the damping half-ring limit the ink bottle, increasing the friction when the ink bottle is held in place and improving the stability of the ink bottle when filling it with ink. Additionally, the protective ring seals the top of the ink bottle to prevent watercolor pen ink from splashing out during filling.

[0004] However, in the production process of colored pencils, the limiting semi-rings are connected to the fixed plate by a return spring, without a specific limiting component. Therefore, the opposing limiting semi-rings are prone to tilting, which is not conducive to positioning and filling. Moreover, during filling, ink will inevitably remain on the lower side of the filling head, which is easy to drip onto the upper side of the base plate, which is not conducive to use. Therefore, there is still room for further improvement.

[0005] Therefore, we propose a quantitative filling device for colored pens to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a quantitative filling device for colored pens, in order to solve the problem mentioned in the background art that in the production process of colored pens, the limiting semi-ring is connected to the fixed plate by a return spring and there is no specific limiting component. Therefore, the opposing limiting semi-rings are prone to tilting, which is not conducive to positioning and filling. Moreover, during filling, ink will inevitably remain on the lower side of the filling head and easily drip onto the upper side of the bottom plate, which is not conducive to use. Therefore, there is still room for further improvement.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a quantitative filling device for colored pencils, comprising: A base plate, wherein a bracket is provided on the upper side of the base plate, and a pen and ink box is provided on the side of the bracket; Also includes: The front side of the bracket is provided with a filling mechanism for precisely controlling the filling amount, and the top of the base plate is provided with a collection mechanism for collecting ink. The upper side of the base plate is provided with a positioning mechanism for placing the pen holder, and the pen holder is tightly fitted with the arc-shaped ring.

[0008] The positioning mechanism is composed of a vertical plate, a sliding rod, an arc ring, a connecting cylinder, a connecting bolt, and a return spring. The vertical plate is set on the upper side of the base plate and is arranged in an array. The vertical plate is slidably connected to the sliding rod, and the sliding rod is fixedly connected to the arc ring.

[0009] The arc-shaped ring is fixedly connected to the connecting cylinder, and the connecting cylinder is threadedly connected to the connecting bolt. A return spring is provided on the outer side of the connecting cylinder.

[0010] Preferably, the filling mechanism is composed of a first electric telescopic rod, a connecting frame, a quantitative filling head, a limiting telescopic rod, and an elastic conveying tube. The first electric telescopic rod is located on the front side of the support, and the output end of the first electric telescopic rod is fixedly connected to the connecting frame. The quantitative filling head is provided inside the connecting frame, and the quantitative filling head is distributed in an array.

[0011] Preferably, the limiting telescopic rod is disposed on the rear side of the bracket, and the lower side of the limiting telescopic rod is fixedly connected to the connecting frame, and the upper side of the quantitative filling head is fixedly connected to the elastic conveying tube, and the upper side of the elastic conveying tube is fixedly connected to the pen and ink box.

[0012] Preferably, the collecting mechanism is composed of a second electric telescopic rod, a collecting trough, and a limiting rod. The second electric telescopic rod is located on the right side of the bracket, and the output end of the second electric telescopic rod is fixedly connected to the collecting trough, and the collecting trough is fixedly connected to the limiting rod.

[0013] Preferably, the limiting rod is slidably connected to the bracket, and the limiting rod is symmetrical about the vertical central axis of the bracket.

[0014] Compared with the prior art, the beneficial effects of this utility model are: After the filling of the colored pen quantitative filling equipment is completed, the second electric telescopic rod is activated to move the collection tank to the right, thereby preventing ink from dripping when the pen holder is replaced, which helps to keep the working environment clean and tidy. When the return spring needs to be replaced, the connecting bolt is disconnected from the connecting cylinder, and the sliding rod on the side of the arc ring and the connecting cylinder are disconnected from the vertical plate, ensuring that the return spring has good elastic potential energy and is convenient for clamping the pen holder. 1. It is equipped with a first electric telescopic rod, a connecting frame and a quantitative filling head. The lower side of the first electric telescopic rod is fixedly connected to the connecting frame. When the first electric telescopic rod is working, the first electric telescopic rod will move up and down with the quantitative filling head through the connecting frame, so as to facilitate the quantitative filling head to fill the ink in the ink box into the pen holder. 2. It is equipped with a second electric telescopic rod, a collection trough and a limit rod. After filling is completed, the quantitative filling head is moved up, and then the second electric telescopic rod is activated. The second electric telescopic rod will move the collection trough to the right, thereby preventing ink from dripping when changing pen holders and helping to keep the working environment clean and tidy. 3. It is equipped with a vertical plate, a sliding rod and an arc ring. The arc ring is slidably connected to the vertical plate through the sliding rod and the connecting cylinder, and the sliding rod plays a limiting role to facilitate the horizontal movement of the arc ring; 4. It is equipped with a connecting cylinder, connecting bolts and a return spring. When the pen holder is placed inside the arc-shaped ring, the arc-shaped ring will move outward. At this time, the return spring will undergo elastic deformation, which is beneficial for clamping the pen holder. 5. It is equipped with an arc-shaped ring, connecting bolts, and a return spring. When the return spring needs to be replaced, disconnect the connecting bolts from the connecting cylinder. This will disconnect the sliding rod on the side of the arc-shaped ring and the connecting cylinder from the vertical plate, ensuring that the return spring has good elastic potential energy and making it easy to hold the pen holder.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Please see Figures 1-4 As shown, this utility model provides a technical solution: a quantitative filling device for colored pens, comprising: a base plate 1, a support 2, an ink box 3, a first electric telescopic rod 4, a connecting frame 5, a quantitative filling head 6, a limiting telescopic rod 7, an elastic conveying pipe 8, a second electric telescopic rod 9, a collection trough 10, a limiting rod 11, a pen holder 12, a vertical plate 13, a sliding rod 14, an arc-shaped ring 15, a connecting cylinder 16, a connecting bolt 17, and a return spring 18.

[0019] In the existing production process of colored pencils, the limiting semi-ring is connected to the fixed plate by the return spring 18, without a specific limiting component. Therefore, the opposing limiting semi-rings are prone to tilting, which is not conducive to positioning and filling. Moreover, during filling, ink will inevitably remain on the lower side of the filling head, which is easy to drip onto the upper side of the base plate 1, which is not conducive to use. Therefore, there is still room for further improvement.

[0020] like Figure 1 and Figure 4 As shown, when filling the colored pencils, the pencil holder 12 is inserted between two opposing arc-shaped rings 15. The upper side of the arc-shaped rings 15 is an inwardly sloping arc, so the pencil holder 12 can be easily inserted into the arc-shaped rings 15. Since the side of the arc-shaped rings 15 is provided with a sliding rod 14 and a connecting cylinder 16, and both the sliding rod 14 and the connecting cylinder 16 are slidably connected to the vertical plate 13, the arc-shaped rings 15 will push the sliding rod 14 and the connecting cylinder 16 to slide within the vertical plate 13. The vertical plate 13, the sliding rod 14, the arc-shaped rings 15, the connecting cylinder 16, the connecting bolt 17, and the return spring 18 are arranged opposite to each other. Therefore, when the pencil holder 12 is inserted into the inner side of the arc-shaped rings 15, the opposing arc-shaped rings 15 will move synchronously.

[0021] It should be noted that, as Figure 3 As shown, if the elasticity of the return spring 18 deteriorates, rotate the connecting bolt 17 to disconnect it from the connecting cylinder 16. Then push the arc ring 15 in the opposite direction. At this time, the arc ring 15 will disconnect from the corresponding vertical plate 13, thereby removing the return spring 18 on the outside of the connecting cylinder 16 and replacing it with a new return spring 18. Then connect the arc ring 15 to the vertical plate 13 in the reverse order and thread the connecting bolt 17 to the connecting cylinder 16. The connecting bolt 17 has a limiting function to prevent the arc ring 15 from disconnecting from the vertical plate 13.

[0022] like Figure 1 , Figure 2 and Figure 4 As shown, during filling, the first electric telescopic rod 4 is activated. When the first electric telescopic rod 4 is working, it will move up and down with the quantitative filling head 6 through the connecting frame 5. The upper side of the connecting frame 5 is fixedly connected to the limiting telescopic rod 7, which has a limiting function, thereby facilitating the quantitative filling head 6 to move down and fill the ink in the ink box 3 into the pen holder 12 through the elastic feed tube 8. The elastic feed tube 8 can extend and retract, which facilitates filling.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, after filling is completed, the quantitative filling head 6 is moved upward, and then the second electric telescopic rod 9 is activated. The second electric telescopic rod 9 will move the collection tank 10 to the right. Since the collection tank 10 is fixedly connected to the limiting rod 11 and the limiting rod 11 is slidably connected to the bracket 2, the limiting rod 11 has a limiting effect on the collection tank 10, which facilitates the horizontal movement of the collection tank 10. This prevents ink from dripping onto the upper side of the bottom plate 1 when replacing the new pen holder 12, which helps to keep the working environment clean and tidy.
