Technical Field
[0001] This utility model belongs to the field of liquid level control devices, specifically relating to a liquid level control device for printing ink. Background Technology
[0002] In the printing industry, ink level control is one of the key links to ensure printing quality and production efficiency. Traditional ink level control methods often rely on manual monitoring, which is not only inefficient but also prone to errors, resulting in too much or too little ink being injected, which in turn affects the quality of printed products, causes ink waste or printing equipment malfunctions. In addition, in some large-scale printing production scenarios, manual monitoring is difficult to meet the requirements of real-time and accuracy.
[0003] Meanwhile, with the development of automation technology, some liquid level control devices have been gradually applied to the printing industry. However, existing devices still have shortcomings in terms of adaptability and reliability. For example, they cannot be flexibly adjusted according to the depth of different ink cartridges and the density of ink, and the reliability of the sensing components needs to be improved, as they are prone to misjudgment or failure. In order to solve the above problems, a liquid level control device for printing ink is proposed. Utility Model Content

[0009] An extension component is detachably mounted at the bottom of the drive component;
[0010] The float is detachably mounted in the extension.
[0011] The float rises with the liquid level and drives the extension and drive components to rise. When the liquid level reaches the warning height, the drive component contacts the sensor.

[0014] Furthermore, the extension includes a shaft; a stud located at the top of the shaft and threaded into the bottom of the sleeve; and a threaded groove at the bottom of the shaft.
[0015] Furthermore, the top of the float is set at stud two, which is screwed into the threaded groove.

[0017] Furthermore, several balls are embedded inside the support frame, and the balls roll and fit against the outer wall of the sleeve; a limit ring is provided on the upper outer wall of the sleeve.
[0018] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:
[0019] This invention relates to a printing ink level control device that not only allows adjustment of the ink level control height, but also allows adjustment of the extension rod distance and replacement of the float ball according to the depth requirements of the ink cartridge and the ink density. This enables the device to adapt to different usage environments and improves its applicability. 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] Please see Figure 1-3 This utility model provides a printing ink level control device, including a sleeve 1; it is installed on the ink cylinder by an external bracket to ensure that the installation is firm and the position is appropriate;
[0026] The sensing element 2 has one end embedded in the outer wall of the sleeve 1;
[0027] Support frame 3 is installed on top of sleeve 1;
[0028] The driving component 4 can slide through the sleeve 1 and the support frame 3 respectively; the support frame 3 provides support and guidance for the driving component 4.
[0029] Extension 5 is detachably mounted at the bottom of drive 4;
[0030] The float 6 is detachably installed in the extension 5;
[0031] When ink is injected into the ink cartridge, the float 6 will rise with the liquid level. Since the float 6 is connected to the extension 5 and the drive 4, it will drive the extension 5 and the drive 4 to rise together. When the liquid level reaches the warning height, the drive 4 will contact the sensor 2. The sensor 2 will sense this state and send it to the remote control center in the form of a signal, so that the remote control center can stop the ink injection.
[0032] Specifically, refer to Figure 2 The sensing element 2 includes a mounting frame 21 with one end embedded in the outer wall of the sleeve 1 and communicating with the inside of the sleeve 1; a drive rod 22 with an inclined surface at one end and sliding through the mounting frame 21; a pressure sensor 23 with one end embedded in the outer end of the mounting frame 21; and a spring 24 disposed in the mounting frame 21 and connected at both ends to the drive rod 22 and the pressure sensor 23 respectively.
[0033] Specifically, refer to Figure 2 The driving component 4 includes a rod sleeve 41 that slides through the sleeve 1 and the support frame 3; a threaded rod 42 that is rotatably disposed inside the rod sleeve 41 and whose top end passes through the rod sleeve 41; a lifting block 43 that is threadedly sleeved on the outer wall of the threaded rod 42 and can slide in the rod sleeve 41, the lifting block 43 slidingly passing through the rod sleeve 41; a driving frame 44 that is sleeved on the outer wall of the lifting block 43 and can slide on the outer wall of the rod sleeve 41, the upper part of the driving frame 44 being conical; and a locking piece 45 that is threadedly sleeved on the upper part of the threaded rod 42 and used to fix the threaded rod 42.
[0034] In this embodiment, when the liquid level reaches the warning height, the drive frame 44 of the drive component 4 will contact the drive rod 22 of the sensor 2. One end of the drive rod 22 has an inclined surface. Under the action of the drive frame 44, the drive rod 22 will slide into the mounting frame 21, compress the spring 24, and trigger the pressure sensor 23. After the pressure sensor 23 senses the pressure change, it sends this state to the remote control center as a signal. After receiving the signal, the remote control center immediately stops the ink injection, thereby realizing the control of the ink level.
[0035] If it is necessary to adjust the height of the liquid level control, the lifting block 43 can be moved up and down on the threaded rod 42 by rotating the threaded rod 42, thereby adjusting the position of the drive frame 44 and changing the liquid level warning height.
[0036] Specifically, referring to Figure 3, the extension member 5 includes a rod body 51; a stud 52 located at the top of the rod body 51 and threaded into the bottom of the rod sleeve 41; and a threaded groove 53 opened at the bottom of the rod body 51.
[0037] In this embodiment, according to the depth requirements of the ink cartridge, an appropriate number of extension pieces 5 are selected, and the studs 52 of the extension pieces 5 are screwed into the bottom of the sleeve 41 to achieve a detachable connection between the extension pieces 5 and the drive piece 4. When it is necessary to adapt to ink cartridges of different depths, the number of extension pieces 5 can be increased or decreased. The detachable design of the extension pieces 5 allows for unlimited splicing according to usage requirements.
[0038] Specifically, refer to Figure 3 The top of the float ball 6 is set on the stud 2 61, and the stud 2 61 is screwed into the threaded groove 53.
[0039] In this embodiment, the stud 61 at the top of the float 6 is screwed into the threaded groove 53 at the bottom of the rod 51 of the extension member 5, thus completing the detachable connection between the float 6 and the extension member 5. When using inks of different densities, floats 6 with different buoyancy can be replaced to ensure that the float 6 can rise accurately with the liquid level. The detachable design of the float 6 provides convenience for this purpose.
[0040] Specifically, refer to Figure 1-3The number of sensors 2 is two and they are symmetrically arranged on the frame 1 to improve reliability and avoid the failure of one side of the sensor 2.
[0041] Specifically, refer to Figure 2 Several balls 7 are embedded inside the support frame 3. The balls 7 roll and fit against the outer wall of the sleeve 41. The balls 7 can reduce the frictional resistance of the drive component 4 during the sliding process. A limit ring 8 is provided on the upper outer wall of the sleeve 41 to prevent the drive component 4 from sliding excessively and causing it to detach from the sleeve 1.
[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
