Description

Technical Field

[0001] This utility model belongs to the field of printing press technology, and in particular relates to a protective device for a printing press viscosity controller. Background Technology

[0002] As the printing industry continues to develop towards higher precision, higher efficiency, and higher quality, the precise control of ink viscosity is crucial for ensuring the color consistency, dot clarity, and production efficiency of printed products. As a key device for real-time monitoring and adjustment of ink viscosity, the performance stability of the printing press viscosity controller directly determines the final quality of the printed products. Therefore, protective devices are needed to ensure its safe and efficient operation.

[0003] However, existing protective devices are not good at buffering impact forces during use. The impact force is directly and rigidly transmitted from the protective plate to the controller, which not only affects the protective effect of the protective plate on the controller, but also increases the damage to the protective plate itself and shortens the service life of the protective plate. Utility Model Content

[0004] The purpose of this utility model is to provide a protective device for a printing press viscosity controller. By setting up a buffer protection part, the existing protective devices are not convenient for buffering impact forces during use. The impact force is directly transmitted to the controller through the rigidity of the protective plate, which not only affects the protective effect of the protective plate on the controller, but also increases the damage to the protective plate itself and shortens the service life of the protective plate.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a protective device for a viscosity controller of a printing press, comprising a controller and further comprising: a plurality of buffer protection parts, all of which are mounted on the controller; a plurality of quick-installation parts, all of which are mounted on the controller; each buffer protection part comprising a buffer assembly mounted on the controller; and an elastic guide assembly mounted on the controller; the buffer assembly comprising a protective plate disposed on the rear side of the controller, the front side of which has a rectangular groove. The inner wall of the rectangular slide groove is slidably connected to two hook-shaped sliders, each of which is provided with a triangular block. An elastic element is provided between the two triangular blocks, and guide elements are provided on the two hook-shaped sliders and the two triangular blocks. The two hook-shaped sliders are symmetrically arranged on the protective plate. The quick-installation part includes a snap-fit ​​assembly located in front of the protective plate and an anti-detachment assembly located behind the controller. The buffer assembly, through the cooperation of the hook-shaped sliders, triangular blocks, elastic element, and guide elements, absorbs and disperses the impact force when the protective plate is subjected to force, providing buffer protection for the controller.

[0007] Furthermore, the elastic guide assembly includes two spring telescopic rods fixedly connected to the front side of the protective plate, and a rectangular plate is fixedly connected to the front side of the two spring telescopic rods; wherein, the two spring telescopic rods are mirror images of each other, and the rear side of the two triangular blocks is fixedly connected to the rectangular plate. The elastic guide assembly, with the help of the spring telescopic rods and the rectangular plate, provides guidance and assists in buffering the movement of the protective plate, thereby enhancing the buffering stability of the protective plate.

[0008] Furthermore, the buckle assembly includes two square blocks fixedly connected to the front side of the rectangular plate, and a cylindrical block rotatably connected to the front side of each of the two square blocks. Several limiting blocks are fixedly connected to the outer walls of each of the two cylindrical blocks. Two cylindrical shells are fixedly connected to the rear side of the controller, and two slots are respectively provided on the two cylindrical shells. The two square blocks are mirror images of each other. The buckle assembly realizes the rapid installation and fixation of the protective device and the controller through the cooperation of the square blocks, cylindrical blocks, limiting blocks and other components.

[0009] Furthermore, the anti-detachment component includes cylindrical grooves respectively formed on the corresponding square blocks, and limit pins are provided on the inner walls of the two cylindrical grooves; wherein, the two limit pins are distributed in a linear array, and the anti-detachment component uses the cylindrical grooves and limit pins to reinforce the installation state of the buckle component and prevent the protective device from accidentally falling off.

[0010] Furthermore, the elastic element includes a spring telescopic rod fixedly connected between the two hook-shaped sliders; wherein, the top and bottom of the spring telescopic rod are provided with gaskets, and the guide element includes T-shaped grooves respectively opened on the side of the two triangular blocks that are close to each other, and T-shaped sliders are slidably connected to the inner walls of the two T-shaped grooves; wherein, the side of the two T-shaped sliders that are close to each other is fixedly connected to the two hook-shaped sliders respectively.

[0011] Furthermore, the slot component includes a limiting block two fixedly connected to the inner wall of the corresponding cylindrical shell, and a rectangular block is fixedly connected to the right side of the limiting block two; wherein, a plurality of rectangular blocks are arranged in a circumferential array on the inner wall of the cylindrical shell.

[0012] This utility model has the following beneficial effects:

[0013] 1. By setting up a buffer protection section, the buffer assembly and the elastic guide assembly work together to achieve buffer protection for the viscosity controller of the printing press. When the controller is impacted, the protective plate drives the hook-shaped slider to move. With the cooperation of the triangular block, elastic element and guide element, the impact force is converted into the deformation energy of the elastic element. At the same time, the spring telescopic rod 2 further absorbs the impact energy during the guiding process. After the impact ends, each component resets under the elastic action, thereby absorbing and dispersing the impact force and avoiding the impact force being directly rigidly transmitted from the protective plate to the controller. This not only enhances the protective effect of the protective plate on the controller, but also reduces the impact damage to the protective plate itself, extends the service life of the protective plate, and ensures that it can continuously and stably play a protective role.

[0014] 2. A quick-installation section, consisting of a snap-fit ​​assembly and an anti-detachment assembly, is designed for rapid installation and disassembly of the protective device and the controller. During installation, initial fixation is achieved by aligning the limiting block in the snap-fit ​​assembly and rotating the component. The limiting pin of the anti-detachment assembly then reinforces the installation, ensuring stability. For disassembly, simply release the limiting pin and reverse the snap-fit ​​assembly. This simplifies the installation and disassembly process, facilitating future maintenance, replacement, or repair of the protective device and the controller, thus improving operational convenience and efficiency.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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 1-5 As shown, this utility model is a protective device for a printing press viscosity controller, including a controller 111, and further including: a buffer protection part 2, of which a plurality of buffer protection parts 2 are provided, and the plurality of buffer protection parts 2 are all provided on the controller 111; and a quick installation part 3, of which a plurality of quick installation parts 3 are provided, and the plurality of quick installation parts 3 are all installed on the controller 111.

[0026] The buffer protection unit 2 includes a buffer assembly 21, which is mounted on the controller 111; and an elastic guide assembly 22, which is mounted on the controller 111. The buffer assembly 21 includes a protective plate 211 located on the rear side of the controller 111. A rectangular groove 212 is provided on the front side of the protective plate 211. Two hook-shaped sliders 213 are slidably connected to the inner wall of the rectangular groove 212. Each of the two hook-shaped sliders 213 is provided with a triangular block 214. An elastic element is provided between the two triangular blocks 214. Guide elements are provided on the two hook-shaped sliders 213 and the two triangular blocks 214. The two hook-shaped sliders 213 are symmetrically arranged on the protective plate 211. The elastic guide assembly 22 includes two spring telescopic rods 221 fixedly connected to the front side of the protective plate 211. A rectangular plate 222 is fixedly connected to the front side of the two spring telescopic rods 221. The two spring telescopic rods 221 are mirror images of each other, and the rear sides of the two triangular blocks 214 are fixedly connected to the rectangular plate 222. The elastic element includes a spring telescopic rod 215 fixedly connected between the two hook-shaped sliders 213. The top and bottom of the spring telescopic rod 215 are provided with pads. The guide element includes T-shaped grooves 216 respectively opened on the side of the two triangular blocks 214 that are close to each other. T-shaped sliders 217 are slidably connected to the inner walls of the two T-shaped grooves 216. The side of the two T-shaped sliders 217 that are close to each other is fixedly connected to the two hook-shaped sliders 213 respectively. By setting the buffer protection part 2, the impact force can be avoided from being directly rigidly transmitted from the protective plate to the controller. This not only enhances the protective effect of the protective plate on the controller, but also reduces the damage to the protective plate itself caused by the impact, extends the service life of the protective plate, and ensures that it can continuously and stably play a protective role.

[0027] The quick-installation unit 3 includes a snap-fit ​​assembly 31, which is located in front of the protective plate 211; and an anti-detachment assembly 32, which is located behind the controller 111. The snap-fit ​​assembly 31 includes two square blocks 311 fixedly connected to the front side of the rectangular plate 222. A cylindrical block 312 is rotatably connected to the front side of each of the two square blocks 311. Several limiting blocks 313 are fixedly connected to the outer walls of each of the two cylindrical blocks 312. Two cylindrical shells 314 are fixedly connected to the rear side of the controller 111. Two slots are provided on each of the two cylindrical shells 314. The two square blocks 311 are mirror images of each other. The anti-detachment assembly 32 includes... A cylindrical groove 321 is formed on the corresponding square block 311, and a limit pin 322 is provided on the inner wall of each of the two cylindrical grooves 321.

[0028] A specific application of this embodiment is as follows: When the protective plate 211 is impacted, it will move towards the rectangular plate 222, thereby compressing the two spring telescopic rods 221. That is, the protective plate 211 will move closer to the rectangular plate 222 under the guidance of the two spring telescopic rods 221. At the same time, the two hook-shaped sliders 213 move accordingly. Since the inclined surface of the corresponding triangular block 214 is slidably connected to the hook-shaped slider 213 through the corresponding T-shaped groove 216 and T-shaped slider 217, the two hook-shaped sliders 213 will move closer to each other under the action of the two triangular blocks 214. At this time, the first spring telescopic rod 215 is compressed until the impact ends. The first spring telescopic rod 215 and the two spring telescopic rods 221... 221 rebounds and resets all components, thereby protecting the controller 111 and buffering and absorbing the impact force. When the protective plate 211 needs to be installed, the first limit block 313 and the second limit block 315 on the device are aligned and inserted. Then, the cylindrical block 312 is rotated until the cylindrical block 312 drives the upper limit block 313 to contact the rectangular block 316. At this time, the limit pin 322 is inserted into the cylindrical groove 321. The limit pin 322 is locked into the upper limit block 313 to complete the fixation. The installation of the protective plate 211 is completed by fixing the other quick installation part 3. Conversely, by lifting the limit pin 322 and reversing the cylindrical block 312, the quick installation part 3 can be opened and the protective plate 211 can be removed.
