Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical packaging printing, specifically to a device for precisely controlling the amount of ink used in pharmaceutical paper boxes. Background Technology

[0002] Pharmaceutical packaging printing aims to provide safe, compliant, and clearly labeled packaging for pharmaceuticals, encompassing various forms such as cartons and bottles. Precise ink control is crucial for ensuring printing quality, reducing costs, and meeting pharmaceutical packaging regulations. It also effectively prevents packaging defects caused by excessive or insufficient ink, further enhancing the overall image of the pharmaceutical product in the market.

[0003] In existing pharmaceutical packaging printing technologies, there are many shortcomings in controlling the amount of ink used in pharmaceutical paper boxes: On the one hand, traditional ink control methods are difficult to adjust precisely, often only allowing for relatively rough ink volume settings. This leads to unstable ink usage during actual printing, easily resulting in too much or too little ink. Too much ink will cause the printed pattern to be blurry and the edges to be unclear, affecting the accurate transmission of pharmaceutical information; too little ink will cause uneven printing colors and incomplete coverage, reducing the aesthetics and recognizability of the packaging. On the other hand, the lack of an effective filtration mechanism means that impurities that may be present in the ink cannot be filtered out in time. These impurities will adhere to the pharmaceutical paper box along with the ink, which not only affects the printing quality but may also pose a potential threat to the safety of the pharmaceutical packaging, failing to meet the strict safety and hygiene standards for pharmaceutical packaging.

[0004] Therefore, we have made improvements to this by proposing a device for precise control of ink usage in pharmaceutical paper boxes. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a device for precisely controlling the amount of ink used in pharmaceutical paper boxes, thus solving the problems mentioned in the background art.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: A device for precisely controlling the amount of ink used in pharmaceutical paper boxes is provided to solve the above problems.

[0007] The application is as follows: The ink container includes an ink tank, an ink outlet pipe is fixedly installed at the lower end of the ink tank, and a fixing block is installed at the lower end of the ink outlet pipe. A control mechanism is provided inside the fixing block, and a filter mechanism is provided on the lower side of the fixing block. The control mechanism includes an ink supply chamber, which is located inside the fixed block and is connected to the ink outlet pipe. The fixed block has a cavity inside, and an elastic diaphragm is fixedly installed inside the cavity on one side of the ink supply chamber.

[0008] As a preferred technical solution of this application, a movable block is slidably connected inside the cavity, and a sealing plug is fixedly installed on one side surface of the movable block. The sealing plug is slidably connected inside the cavity and is made of rubber.

[0009] As a preferred technical solution of this application, a fixing plate is provided between the elastic diaphragm and the sealing plug, and the fixing plate is fixedly installed inside the cavity, and the surface of the fixing plate is uniformly provided with a plurality of holes.

[0010] As a preferred technical solution of this application, a threaded rod is rotatably connected inside the cavity, and the threaded rod is connected to the moving block by a threaded connection. A knob is fixedly installed at the other end of the threaded rod.

[0011] As a preferred technical solution of this application, a pointer is fixedly installed on one side surface of the fixing block, and scale lines are provided on the outer surface of the knob.

[0012] As a preferred technical solution of this application, the filtering mechanism includes a fixed tube, which is fixedly installed on the lower surface of the fixed block and is connected to the ink supply cavity. A connecting tube is provided on the lower side of the fixed tube, and an installation groove is provided on the inner wall of the upper part of the connecting tube. The fixed tube and the installation groove are threaded together. An installation ring is provided inside the installation groove, and a filter screen is fixedly installed on the lower surface of the installation ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. Through the use of the control mechanism, the operator only needs to turn the knob, and the threaded rod will rotate accordingly, driving the moving block and sealing plug to move precisely within the cavity. The sealing plug pushes the elastic diaphragm to deform, cleverly changing the size of the ink supply cavity, thereby finely controlling the amount of ink used. Combined with the pointer and scale, the required amount of ink can be set intuitively and accurately, effectively avoiding problems such as blurry printing and uneven color caused by too much or too little ink, greatly improving the quality and stability of pharmaceutical paper box printing.

[0014] 2. Through the use of the filtration mechanism, the fixed tube is connected to the ink supply chamber, and the connecting tube is connected to the fixed tube via threads. A filter screen is fixedly installed on the mounting ring in the mounting groove. After the ink flows out of the ink supply chamber, it passes through the fixed tube and enters the connecting tube. When passing through the filter screen, impurities in the ink are effectively intercepted, ensuring the purity of the ink entering the printing process. This not only guarantees printing quality but also meets the strict safety and hygiene standards for pharmaceutical packaging. Attached Figure Description

In addition, the terms "first" and "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] To address the technical problems in the background section, the following device for precisely controlling the ink usage of pharmaceutical paper boxes is provided: Combination Figure 1 - Figure 4 As shown, the present invention provides a device for precise control of ink usage in pharmaceutical paper boxes, comprising an ink tank 1, an ink outlet pipe 2 fixedly installed at the lower end of the ink tank 1, and a fixing block 3 installed at the lower end of the ink outlet pipe 2, a control mechanism 4 disposed inside the fixing block 3, and a filter mechanism 5 disposed on the lower side of the fixing block 3; the control mechanism 4 includes an ink supply chamber 401, which is opened inside the fixing block 3 and is connected to the ink outlet pipe 2; a cavity 402 is opened inside the fixing block 3, and an elastic diaphragm 403 is fixedly installed inside the cavity 402 on one side of the ink supply chamber 401.

[0023] In this embodiment, ink flows from ink container 1 through ink outlet pipe 2 fixed at the lower end and enters the position where fixed block 3 is installed. The control mechanism 4 inside fixed block 3 is the core component. Its ink supply chamber 401 is connected to ink outlet pipe 2. The elastic diaphragm 403 in cavity 402 can deform with the control action. With the help of subsequent components, it can adjust the space of ink supply chamber 401, thereby accurately controlling the amount of ink used. The filter mechanism 5 on the lower side of fixed block 3 can filter the ink.

[0024] In a preferred embodiment, a movable block 404 is slidably connected inside the cavity 402, and a sealing plug 405 is fixedly installed on one side surface of the movable block 404. The sealing plug 405 is slidably connected inside the cavity 402 and is made of rubber.

[0025] In this embodiment: the sealing plug 405 is made of rubber. Utilizing the good sealing and flexibility of rubber, when the moving block 404 moves the sealing plug 405, it can effectively ensure a tight fit with the inner wall of the cavity 402, preventing air leakage. When the moving block 404 and the sealing plug 405 move towards the elastic diaphragm 403, they can squeeze the air between the elastic diaphragm 403 and the sealing plug 405, causing the elastic diaphragm 403 to deform and squeeze the ink delivery cavity 401, thus reducing the flow rate. By precisely controlling the moving distance of the moving block 404, precise control of the ink flow rate can be achieved, meeting the strict requirements for ink usage in pharmaceutical paper box printing and effectively improving printing quality.

[0026] In a preferred embodiment, a fixing plate 406 is provided between the elastic diaphragm 403 and the sealing plug 405, and the fixing plate 406 is fixedly installed inside the cavity 402. The surface of the fixing plate 406 is uniformly provided with a plurality of holes 407.

[0027] In this embodiment, the fixed plate 406 can limit and block the moving block 404 and the sealing plug 405, preventing the sealing plug 405 from moving excessively and damaging the elastic diaphragm 403. The holes 407 on the surface ensure that air can flow smoothly between the sealing plug 405 and the elastic diaphragm 403, so that the elastic diaphragm 403 can deform evenly and stably when subjected to pressure, thereby achieving precise control of ink flow.

[0028] In a preferred embodiment, a threaded rod 408 is rotatably connected inside the cavity 402, and the threaded rod 408 is connected to the movable block 404 by a threaded connection. A knob 409 is fixedly installed at the other end of the threaded rod 408.

[0029] In this embodiment: when the operator rotates the knob 409 fixed at the other end of the threaded rod 408, the threaded rod 408 rotates accordingly, and the moving block 404 moves linearly along the axial direction of the threaded rod 408 within the cavity 402, thereby driving the sealing plug 405 to move, achieving precise control over the degree of deformation of the elastic diaphragm 403, and ultimately achieving precise control over the amount of ink used in pharmaceutical paper boxes.

[0030] In a preferred embodiment, a pointer 410 is fixedly mounted on one side surface of the fixing block 3, and a scale line 411 is provided on the outer surface of the knob 409.

[0031] In this embodiment, when the operator rotates the knob 409 to control the amount of ink, they only need to observe the position of the scale line 411 corresponding to the pointer 410 to clearly and accurately know the current adjustment amount. This allows the operator to adjust the amount of ink to the required value more quickly and accurately, greatly improving the convenience of operation and the accuracy of ink usage control.

[0032] In a preferred embodiment, the filter mechanism 5 includes a fixed tube 501, which is fixedly installed on the lower surface of the fixed block 3 and is connected to the ink supply chamber 401. A connecting tube 502 is provided on the lower side of the fixed tube 501, and an installation groove 503 is provided on the upper inner wall of the connecting tube 502. The fixed tube 501 and the installation groove 503 are threadedly connected. An installation ring 504 is provided inside the installation groove 503, and a filter screen 505 is fixedly installed on the lower surface of the installation ring 504.

[0033] In this embodiment, the fixing tube 501 is securely installed on the lower surface of the fixing block 3 and communicates with the ink supply chamber 401, providing a smooth channel for ink flow. The fixing tube 501 and the connecting tube 502 are connected by a threaded connection through the mounting groove 503. This connection method not only facilitates installation and disassembly, making it easy to clean and replace the filter components, but also ensures a tight connection to prevent ink leakage. The mounting ring 504 set in the mounting groove 503 and the filter bag 505 fixed on its lower surface can effectively intercept impurities in the ink, ensuring the purity of the ink entering the subsequent printing process, thereby improving the printing quality of the pharmaceutical paper box.

[0034] Specifically, the working principle of this solution is as follows: Ink flows from ink container 1 through ink outlet tube 2 into ink delivery chamber 401 within fixed block 3. Rotating knob 409 rotates threaded rod 408, causing threaded movable block 404 to move linearly within cavity 402, which in turn moves sealing plug 405, made of rubber with good sealing and flexibility. A fixed plate 406 is positioned between sealing plug 405 and elastic diaphragm 403, with holes 407 ensuring smooth airflow. The movement of sealing plug 405 compresses the air between them, causing elastic diaphragm 403 to deform uniformly, compressing ink delivery chamber 401 and changing its size to precisely control ink flow. During operation, observing the position of pointer 410 on fixed block 3 corresponding to the scale line 411 of knob 409 allows for quick and accurate determination of the adjustment amount.

[0035] Ink flows into the filter mechanism 5 through the ink supply chamber 401. The fixed tube 501 and the connecting tube 502 are connected by a threaded connection through the mounting groove 503 for easy assembly and disassembly. As the ink flows through, the filter screen 505 on the lower surface of the mounting ring 504 effectively intercepts impurities, ensuring the purity of the ink entering subsequent printing stages. This ultimately achieves precise control over the amount of ink used in pharmaceutical paper boxes, improving printing quality.

[0036] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0037] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
