Description
Technical Field
[0001] This utility model relates to an ink supply cartridge for filtering ink, belonging to the field of printing ink filtration technology. Background Technology
[0002] In the printing industry, film thickness has a crucial impact on product quality, performance, and appearance. For example, in electronic circuit printing, uneven film thickness can lead to problems such as short circuits, open circuits, and insufficient resistance, severely affecting the performance and stability of electronic products. To improve printing quality and ensure product stability, printing accuracy can be guaranteed by reducing the impurity content in the ink during ink supply. However, in practice, a simple method of ink filtration uses a fixed-structure filter. While convenient, this filter structure easily accumulates impurities on its surface, reducing filtration efficiency. Furthermore, it requires frequent replacement or cleaning over time, making long-term operation cumbersome and affecting normal ink supply. Therefore, to simplify the filtration process, a filter structure that requires less frequent maintenance is urgently needed. Summary of the Invention
[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an ink supply cartridge for filtering ink. It is used for filtering ink before ink supply and can eliminate the need for frequent maintenance or replacement while ensuring high filtration efficiency. It can effectively reduce the complexity of ink supply operation and ensure good ink supply quality.
[0004] To achieve the above objectives, this utility model employs the following technical solution: This utility model provides an ink supply box for filtering ink, including an ink supply chamber. A feeding roller and a receiving roller are rotatably mounted on both sides of the ink supply chamber. A motor for driving the receiving roller is also provided on the ink supply chamber. A feeding tube is installed inside the ink supply chamber, and the feeding tube has a through-hole. Several guide rollers are also provided inside the ink supply chamber. A composite filter cloth is wound around the feeding roller. The composite filter cloth is guided and wound onto the receiving roller by the guide rollers. The guide rollers are positioned to allow the composite filter cloth to pass through the through-hole at the bottom of the feeding tube. A cylinder is also provided on the ink supply chamber. A connecting block is provided on the output shaft of the cylinder. A pressure plate that can slide along the wall of the ink supply chamber is mounted on the connecting block. The width of the pressure plate is sufficient to cover the width of the through-hole.
[0005] Specifically, the feeding tube is provided with two protruding edges that are flush with the bottom surface of the corresponding through-hole, and the bottom of the pressure plate matches the shape of the upper surface of the protruding edges.
[0006] Specifically, the composite filter cloth has a multi-layer structure, and the bottom layer of the composite filter cloth has a pore size that can filter impurities as small as 5 μm.
[0007] Specifically, the internal space of the ink supply box decreases in a stepped manner from top to bottom, and an ink supply trough is connected to the bottom of the ink supply box. An ink supply port for supplying ink to the ink roller is opened at the bottom of the ink supply trough.
[0008] Specifically, an ink inlet groove is provided above the ink supply box, and a guide tube is connected to the bottom of the ink inlet groove. The ink outlet of the guide tube is located above the discharge tube or inside the discharge tube.
[0009] Specifically, the top of the ink supply box is provided with abutment strips on both sides, and mounting plates are positioned on the two abutment strips. The cylinder is fixedly mounted on the mounting plate, and the mounting plate is also provided with a handle.
[0010] Specifically, the convex edge is annular in shape around the feed tube, and the bottom of the pressure plate can form an annular surface to press against the convex edge.
[0011] Specifically, the extension direction of the discharge tube is vertical, the liquid inlet of the discharge tube faces upward and the liquid outlet faces horizontal. Two sets of the discharge tube and the corresponding composite filter cloth are provided. Two sets of cylinders are provided and are located on both sides of the ink supply box. The two cylinders are respectively connected to two pressure plates to press the corresponding composite filter cloth along the wall of the discharge tube.
[0012] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This invention uses a composite filter cloth to pass through an opening in the discharge pipe and utilizes the pressure plate to form a stable sealing surface with the discharge pipe, allowing the composite filter cloth to complete its normal filtration function. After filtration is completed, as the service life is extended, the filter surface can be quickly switched by loosening the pressure plate and rotating the receiving roller. This allows the used filter surface to be switched to the reverse and the unfiltered filter surface to be replaced, thus ensuring filtration efficiency. The operation is more convenient and does not require manual disassembly and maintenance, simplifying the work. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.
[0015] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example:
[0017] This utility model provides an ink supply box for filtering ink, used for filtering ink before ink supply. It eliminates the need for frequent maintenance or replacement while ensuring high filtration efficiency, effectively reducing the complexity of ink supply operations and ensuring good ink supply quality. To achieve the structural performance of the ink supply box and simplify manual operation, the device includes an ink supply box 1, with a feed roller 2 and a take-up roller 3 rotatably mounted on both sides of the ink supply box 1. A motor 4 is mounted on the ink supply box 1 to drive the take-up roller 3 to rotate. (Refer to...) Figure 1 as well as Figure 3 As shown, the ink supply box 1 is equipped with a discharge pipe 6, which has a through-hole. The ink supply box 1 also contains several guide rollers 7. At this time, a composite filter cloth 5 is wound around the discharge roller 2, allowing it to be guided and wound onto the take-up roller 3 via the guide rollers 7. (Refer to...) Figure 3 The connection configuration shown is such that the guide roller 7 is positioned to allow the composite filter cloth 5 to pass through the opening at the bottom of the feed tube 6. In this connection state, when the motor 4 drives the take-up roller 3 to rotate, the composite filter cloth 5 discharged by the feed roller 2 will be driven by the guide roller 7. Since the composite filter cloth 5 covers the filter surface inside the feed tube 6, the composite filter cloth 5 forms a movable filter layer. To ensure stable operation of the filter layer, a cylinder 9 is also provided on the ink supply box 1. Figure 3 As shown, a connecting block 10 is provided on the output shaft of cylinder 9, and a pressure plate 11 that can slide along the wall of ink supply box 1 is installed on the connecting block 10. The width of the pressure plate 11 is set to cover the width of the opening. With this structural configuration, when cylinder 9 pushes the pressure plate 11 down, it can form a tight closure on the composite filter cloth 5 located at the edge of the feed tube 6, thereby forming a stable filter surface in the feed tube 6. After the filter cloth used for filtration in this part deteriorates in performance after a period of use, the position of the filter cloth can be shifted by releasing the pressure plate 11 and rotating the take-up roller 3, thereby automatically replacing the filter cloth surface. This can simplify manual work while ensuring the filtration effect and has good application prospects.
[0018] This utility model provides an ink supply cartridge for filtering ink. In some embodiments, to avoid instability, warping, or deformation of the pressure plate 11 when pressing the edge of the filter cloth due to its thickness, two protruding edges 8 that are flush with the bottom surface of the corresponding through-hole can be provided on the feed tube 6. Figure 4As shown, the bottom of the pressure plate 11 is used to press the filter cloth onto the convex edge 8, thereby forming a stable fixation and preventing abnormal deformation. The bottom of the pressure plate 11 should match the shape of the upper surface of the convex edge 8. In some preferred embodiments, the convex edge 8 can be configured to form an annular shape around the discharge pipe 6. In this case, the bottom of the pressure plate 11 can form an annular surface to press against the convex edge 8, thereby stabilizing the sealing structure and ensuring that material does not easily leak from the sides.
[0019] This utility model provides an ink supply cartridge for filtering ink. In order to ensure the filtration of impurities, the composite filter cloth 5 can be configured with a multi-layer structure. For example, the filtration pore size of the bottom layer of the composite filter cloth 5 is sufficient to filter impurities of 5μm. Here, it is controlled that impurities larger than 5μm can be intercepted by the bottom layer, while larger impurities are intercepted by other layers of the composite filter cloth 5.
[0020] This utility model provides an ink supply box for filtering ink. In order to facilitate the stable collection of filtered ink and its supply to the printing roller, the internal space of the ink supply box 1 can be set to decrease in a stepped manner from top to bottom, so as to form a sufficient filtration space above the ink supply box 1 and ensure that the filtration area is large enough. In order to facilitate ink supply, an ink supply trough 12 is connected to the bottom of the ink supply box 1. The bottom of the ink supply trough 12 is provided with an ink supply port for supplying ink to the ink roller. The ink is collected and then supplied stably through the ink supply port.
[0021] This utility model provides an ink supply box for filtering ink. In some embodiments, considering that a cylinder 9 is installed above the ink supply box 1, it can easily cause obstruction during ink feeding. To facilitate ink feeding, an ink inlet groove 13 can be provided above the ink supply box 1, such as... Figure 3 As shown, the bottom of the ink inlet trough 13 is connected to a guide tube 14. The ink outlet of the guide tube 14 is located above or inside the discharge tube 6, so that the ink material that can be easily entered by the ink inlet trough 13 can be accurately guided into the discharge tube 6 for filtration. In some other embodiments, the cylinder 9 can be removed for ink refilling. For this purpose, abutment strips can be provided on both sides of the top of the ink supply box 1, and mounting plates 15 are positioned on the two abutment strips. The cylinder 9 is then fixed on the mounting plate 15, and a handle 16 is provided on the mounting plate 15. With this structure, the cylinder 9 can be directly lifted by the handle 16 to remove the entire assembly connected to it, thus facilitating replacement, maintenance, or ink refilling.
[0022] This utility model provides an ink supply cartridge for filtering ink. To achieve step-by-step filtration by adding different filter layers, in some other embodiments, the extension direction of the discharge tube 6 can be configured to be vertical. In this case, the inlet of the discharge tube 6 faces upward and the outlet faces horizontally (the other surfaces are sealing surfaces). Two sets of the inlet and the corresponding composite filter cloth 5 are provided, and two sets of cylinders 9 are also provided, located on both sides of the ink supply box 1 (not shown in the figure). The two cylinders 9 are connected to two pressure plates 11 to press the corresponding composite filter cloth 5 along the wall of the discharge tube 6. This structure can avoid rapid clogging by dividing the filtration layers. The means of monitoring ink flow clogging is not further limited here; for example, a liquid level sensor can be used, as long as it is feasible.
[0023] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
