Abstract
Description
Technical Field
[0001] This utility model relates to the field of adapter technology, specifically an ink inlet adapter for a book and magazine rotary press. Background Technology
[0002] A rotary printing press is a common type of printing equipment that uses rollers for printing; it is also known as a web-fed printing press.
[0003] As a type of large-scale printing equipment, the ink supply system of a book and magazine rotary press uses a pump-and-ink-tank design. A peristaltic pump extracts ink from the ink tank and delivers it to the printhead of the rotary press via a flexible hose. Since different sizes of rotary presses have different inlet sizes for their printheads, an adapter is usually required. The adapter connects to the printhead via a flexible hose. Currently, most adapters on the market are similar in overall structure, consisting of a housing with connectors of different sizes fixed on both sides. However, this design has some functional limitations and room for improvement. For example, since different sizes of rotary presses have different inlet sizes for their inkjet mechanisms, the adapter's outlet size must be compatible when connecting the hose. Currently, adapters are purchased according to the specific model, resulting in an integrated structure. If the outlet is damaged, the entire adapter needs to be replaced, which is costly and lacks the feature of replaceable outlets.
[0004] Now, a new type of ink inlet adapter for a book and periodical rotary press is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide an ink inlet adapter for a book and magazine rotary press, so as to solve the problem mentioned in the background art of not having a replaceable ink outlet.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an ink inlet adapter for a book and magazine rotary press, comprising an adapter body, a bottom fixing plate fixedly connected to the bottom end of the adapter body, an ink outlet provided on the right side of the adapter body, an ink inlet fixedly connected to the left side of the adapter body, and an adapter assembly with replaceable connectors provided on the right side of the adapter body.
[0007] The adapter assembly includes a conductive cavity, which is located inside the right side of the adapter body. An internal threaded cavity is provided on the right side of the conductive cavity. A pressure plate is fixedly connected to the left side of the ink outlet. An external hexagonal fixing block is fixedly connected to the right side of the pressure plate. A conductive tube is fixedly connected to the left side of the pressure plate. A first external threaded tube is fixedly connected to the right side of the conductive tube. A first sealing ring is sleeved on the right side of the first external threaded tube. A second sealing ring is sleeved on the right side of the conductive tube.
[0008] As a further technical solution of this utility model, the ink outlet and the internal connection of the conductive tube are connected, and the horizontal center lines of the ink outlet and the conductive tube coincide.
[0009] As a further technical solution of this utility model, the internal threaded cavity is threaded inside, and the thread inside the internal threaded cavity matches the thread outside the first external threaded tube.
[0010] As a further technical solution of this utility model, the outer diameter of the conductive tube and the inner diameter of the conductive cavity are consistent, and the outer diameter of the first external threaded tube and the inner diameter of the internal threaded cavity are adapted to each other.
[0011] As a further technical solution of this utility model, a filter ring is horizontally placed on the left side inside the conductive cavity, a polypropylene filter element is provided inside the filter ring, and a third sealing ring is glued to the left and right sides of the filter ring respectively. The outer diameters of the conductive tube and the filter ring are the same, and the third sealing rings are symmetrically distributed about the vertical center line of the filter ring.
[0012] As a further technical solution of this utility model, a second external threaded tube is fixedly connected to the outside of the right side of the ink inlet, an internal threaded tube sleeve is sleeved on the outside of the ink inlet, and a closing ring is fixedly connected to the left side inside the internal threaded tube sleeve. The threads inside the internal threaded tube sleeve and the threads outside the second external threaded tube match each other, and the closing ring is in the shape of a flared tube with a smaller left side and a larger right side.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the ink inlet adapter for the book and magazine rotary press not only realizes the function of replaceable outlet, but also realizes the function of filtering and buffering, and also realizes the function of fastening the inlet pipe;
[0014] (1) By setting up an ink outlet, an external hexagonal fixing block, a pressure plate, a first external threaded tube, a guide tube, a first sealing ring, a second sealing ring, a guide cavity, and an internal thread cavity, when in use, the output hose of the peristaltic pump is connected to the ink inlet, and the ink is pumped into the body of the adapter through the ink inlet. The ink enters the inlet hose of the inkjet mechanism along the guide tube and the ink outlet. According to the inlet specification of the inkjet mechanism, the corresponding ink outlet can be selected. The ink outlet, the external hexagonal fixing block, the pressure plate, the first external threaded tube, and the guide tube constitute a set of modular outlet components. The guide tube is inserted along the guide cavity, the first external threaded tube and the internal thread cavity are locked, and the first sealing ring and the second sealing ring increase the sealing of the connection, realizing the function of replaceable outlet.
[0015] (2) By setting up a filter ring, a polypropylene filter element and a third sealing ring, when in use, the ink passes through the filter ring before entering the conduit. The polypropylene filter element inside the filter ring can intercept particulate matter in the ink to prevent the nozzle from clogging. At the same time, it can buffer the ink and reduce its pressure. The third sealing ring increases the sealing performance and realizes the filtering and buffering function.
[0016] (3) By setting a second external threaded tube, an ink inlet, an internal threaded tube sleeve and a sealing ring, when in use, first pass the hose through the internal threaded tube sleeve. As the peristaltic pump hose is sleeved outside the ink inlet and pressed against it, push the internal threaded tube sleeve towards the second external threaded tube and tighten it. The sealing ring then squeezes the hose inward. With the pagoda-shaped ink inlet, the hose head can be pressed against it to prevent leakage or detachment, thus realizing the function of fastening the feed port pipe. Attached Figure Description

[0024] 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.
[0025] Example: Please refer to Figure 1-6 An ink inlet adapter for a book and magazine rotary press includes an adapter body 1, a bottom fixing plate 2 fixedly connected to the bottom end of the adapter body 1, an ink outlet 3 provided on the right side of the adapter body 1, an ink inlet 16 fixedly connected to the left side of the adapter body 1, and an adapter assembly with replaceable connectors provided on the right side of the adapter body 1.
[0026] Please see Figure 1-6 An ink inlet adapter for a book and magazine rotary printer also includes an adapter assembly. The adapter assembly includes a through cavity 10, which is located inside the right side of the adapter body 1. An internal thread cavity 11 is provided on the right side of the through cavity 10. A pressure plate 5 is fixedly connected to the left side of the ink outlet 3. An external hexagonal fixing block 4 is fixedly connected to the right side of the pressure plate 5. A through tube 7 is fixedly connected to the left side of the pressure plate 5. A first external thread tube 6 is fixedly connected to the right side of the outside of the through tube 7. A first sealing ring 8 is sleeved on the right side of the outside of the first external thread tube 6. A second sealing ring 9 is sleeved on the right side of the outside of the through tube 7.
[0027] The ink outlet 3 and the guide tube 7 are internally connected, and the horizontal center lines of the ink outlet 3 and the guide tube 7 coincide. The internal threaded cavity 11 is threaded, and the internal thread of the internal threaded cavity 11 matches the external thread of the first external threaded tube 6. The outer diameter of the guide tube 7 is consistent with the inner diameter of the guide cavity 10, and the outer diameter of the first external threaded tube 6 is adapted to the inner diameter of the internal threaded cavity 11, so that the outlet can be flexibly changed.
[0028] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, according to the inlet specifications of the inkjet mechanism, an ink outlet 3 of the corresponding specifications can be selected. The ink outlet 3, the external hexagonal fixing block 4, the pressure plate 5, the first external threaded tube 6, and the guide tube 7 constitute a set of modular outlet components. The guide tube 7 is inserted along the guide cavity 10, and the first external threaded tube 6 and the internal threaded cavity 11 are locked together. The first sealing ring 8 and the second sealing ring 9 increase the sealing of the connection.
[0029] A filter ring 12 is horizontally placed on the left side inside the conduit cavity 10. A polypropylene filter element 13 is installed inside the filter ring 12. A third sealing ring 14 is glued to the left and right sides of the filter ring 12 respectively. The outer diameters of the conduit tube 7 and the filter ring 12 are the same. The third sealing rings 14 are symmetrically distributed about the vertical center line of the filter ring 12, which facilitates the filtering of ink.
[0030] Specifically, such as Figure 2 and Figure 6 As shown, the polypropylene filter element 13 inside the filter ring 12 can intercept particulate matter in the ink to prevent the printhead from clogging, and at the same time buffer the ink to reduce its pressure. The third sealing ring 14 increases the sealing performance.
[0031] A second external threaded tube 15 is fixedly connected to the outside of the ink inlet 16 on the right side. An internal threaded tube sleeve 17 is sleeved on the outside of the ink inlet 16. A closing ring 18 is fixedly connected to the left side inside the internal threaded tube sleeve 17. The threads inside the internal threaded tube sleeve 17 match the threads outside the second external threaded tube 15. The closing ring 18 is flared with the left side smaller and the right side larger, which makes it easy to compress the hose.
[0032] Specifically, such as Figure 1 and Figure 2 As shown, the hose first passes through the internal threaded sleeve 17. As the peristaltic pump hose is sleeved outside the ink inlet 16 and pressed against it, the internal threaded sleeve 17 is pushed towards the second external threaded tube 15 and tightened. The sealing ring 18 then squeezes the hose inward. Together with the pagoda-shaped ink inlet 16, the end of the hose can be pressed against the tube to prevent leakage or detachment.
[0033] Working Principle: In use, the peristaltic pump's output hose is first connected to the ink inlet 16, pumping ink into the adapter body 1 through the ink inlet 16. The ink then flows along the guide tube 7 and ink outlet 3 to the inlet hose of the inkjet mechanism. Depending on the inlet specifications of the inkjet mechanism, a corresponding ink outlet 3 can be selected. The ink outlet 3, the external hexagonal fixing block 4, the pressure plate 5, the first external threaded tube 6, and the guide tube 7 constitute a modular outlet component. The guide tube 7 is inserted along the guide cavity 10, and the first external threaded tube 6 and the internal threaded cavity 11 are locked together. The first sealing ring 8 and the second sealing ring 9 enhance the sealing of the connection. Before entering the guide tube 7, the ink passes through the filter ring 12. The polypropylene filter element 13 inside the filter ring 12 intercepts particulate matter in the ink, preventing printhead clogging and buffering the ink to reduce its pressure. The third sealing ring 14 further enhances the sealing. First, pass the hose through the internal threaded sleeve 17. As the peristaltic pump hose is fitted over the ink inlet 16 and pressed against it, push the internal threaded sleeve 17 towards the second external threaded tube 15 and tighten it. The sealing ring 18 then squeezes the hose inward. Together with the pagoda-shaped ink inlet 16, the end of the hose can be pressed against the tube to prevent leakage or detachment.
