Description

Technical Field

[0001] This invention relates to the field of printing roller processing technology, specifically to a chrome plating system for printing rollers. Background Technology

[0002] As a core component of printing equipment, the surface hardness, wear resistance, and smoothness of printing rollers directly affect printing quality and service life. Therefore, chrome plating is a crucial process in the manufacturing of printing rollers. The chrome plating process typically involves several key steps, including roller handling, positioning and installation, degreasing and copper removal, and chrome plating. Each step relies on corresponding processing equipment working in concert. Currently, the equipment used for chrome plating of printing rollers in the industry is mostly distributed, with each process's equipment operating independently. The lack of a unified coordination mechanism means that the transfer of printing rollers between processes requires multiple transfers using various handling tools, increasing operational steps and reducing processing efficiency.

[0003] In the existing technology, due to the lack of an integrated processing system specifically adapted to the entire process of chrome plating of printing rollers, there are still many problems in actual processing: on the one hand, the coordination accuracy between the handling mechanism and the installation equipment is insufficient, which can easily lead to the installation and positioning deviation of the printing roller, thus affecting the uniformity of subsequent degreasing and chrome plating; on the other hand, the layout of the degreasing structure and the chrome plating structure is unreasonable, and it is impossible to form an efficient connection with the handling mechanism. This makes it easy for impurities to adhere to the surface of the printing roller when it is transferred to the chrome plating process after degreasing. At the same time, the decentralized structural design also increases the space occupied by the equipment and the complexity of operation, which seriously restricts the large-scale and efficient production of chrome plating of printing rollers.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-7 This invention provides a technical solution: Please refer to [link / reference]. Figures 1-7 This invention provides a technical solution: a chrome plating system for printing rollers, used for chrome plating printing rollers 5. The previous step before chrome plating is copper plating, which facilitates engraving on the printing rollers 5. Now, it is necessary to remove the copper and plate chrome to improve the hardness of the printing rollers 5, including: A moving unit, used for clamping and transporting the printing roller 5, includes a crane frame 1, a transport mechanism 2, and a connecting structure 3. The crane frame 1 is also equipped with a slide rail 11, which defines the movement trajectory of the transport mechanism 2. The transport mechanism 2 is connected to the slide rail 11, and moves laterally on the slide rail 11, thereby loading the printing roller 5 and moving it to the corresponding step, such as the degreasing structure 7 and the chrome plating structure 8. The connecting structure 3 is located on the transport mechanism 2 and is used to connect the printing roller 5.

[0020] The conveying mechanism 2 includes a crane 21, which has a built-in driver that can move the crane 21 on the slide rail 11 and also drive the traction chain 23. The crane 21 is connected to the slide rail 11 and moves on the slide rail 11. The bottom of the crane 21 is provided with a limiting plate 22, which is used to limit the moving plate 24 to ensure that the moving plate 24 can move vertically downward and drive the hook plate 25 to move downward synchronously. The moving plate 24 is provided between the limiting plates 22 and is used to connect with the connecting structure 3. The moving plate 24 is connected to the connecting shaft 26, which connects the hook plate 25 to the moving plate 24. The moving plate 24 is provided with a traction chain 23, which is connected to the crane 21. The crane 21 uses the traction chain 23 to control the movement of the moving plate 24. When the movable plate 24 moves downward, the hook plate 25 is blocked by the snap-fit ​​connector 32 and rotates through the connecting shaft 26, causing the movable plate 24 and the hook plate 25 to fold. This allows the hook plate 25 to pass through the snap-fit ​​connector 32 and be located below it. When the hook plate 25 is below the snap-fit ​​connector 32, the movable plate 24 is driven upward by the traction chain 23. At this time, the hook plate 25 is affected by its width and the connection position of the connecting shaft 26 and will not rotate downward. Instead, the hook plate 25 will drive the snap-fit ​​connector 32 to move upward.

[0021] The overhead crane 21 has a built-in driver, which can move the overhead crane 21 along the slide rail 11 to adjust the transport position, and drive the traction chain 23 to move, thereby controlling the movement of the moving plate 24 connected to the traction chain 23. The limiting plate 22 at the bottom of the overhead crane 21 will limit the movement of the moving plate 24, ensuring that the moving plate 24 moves vertically and drives the hook plate 25 connected to it via the connecting shaft 26 to move synchronously. When it is necessary to connect to the connecting structure 3, the overhead crane 21 controls the moving plate 24 to move downward through the traction chain 23. At this time, the hook plate 25 will be engaged by the connecting structure 3. The obstruction of head 32 causes the connecting shaft 26 to rotate, causing the moving plate 24 and hook plate 25 to fold, allowing the hook plate 25 to pass through the clamping joint 32 and be located below the clamping joint 32. When the hook plate 25 reaches below the clamping joint 32, the overhead crane 21 drives the moving plate 24 to move upward via the traction chain 23. At this time, the hook plate 25 cannot rotate downward due to its own width and the connection position with the connecting shaft 26. Then, the hook clamping joint 32 drives the connecting structure 3 and the printing roller 5 connected to the connecting structure 3 to move upward together, completing the clamping and transportation preparation of the printing roller 5.

[0022] The connecting structure 3 includes two connecting plates 31 arranged in a mirror image to ensure connection between the push rod 35 and the fixing rod 36. The two connecting plates 31 are fixed by the connecting rod 33. All connecting plates 31 have snap-fit ​​connectors 32 on their outer sides, which are used to connect the conveying mechanism 2 and the connecting structure 3 with the hook plate 25. A linear rotary motor 34 is connected to one of the connecting plates 31, and a push rod 35 is connected to the linear rotary motor 34. The linear rotary motor 34 moves the push rod 35 inward, thereby pushing and squeezing the printing rollers 5 placed on the mounting machine 4 and fixing and clamping all the printing rollers 5 placed on the mounting machine 4. A fixing rod 36 is connected to the other connecting plate 31, and the fixing rod 36 is fixed on one side and does not move independently. The push rod 35 and the fixing rod 36 are used to fix the printing rollers 5.

[0023] The core of the connecting structure 3 consists of two mirror-image opposing connecting plates 31. The two connecting plates 31 are fixed together by connecting rods 33 to form a stable frame. This configuration ensures that the two connecting plates 31 are stably connected to the push rod 35 and the fixed rod 36 respectively. All connecting plates 31 have snap-fit ​​connectors 32 on their outer sides. The core function of the snap-fit ​​connectors 32 is to cooperate with the hook plate 25 of the conveying mechanism 2 to achieve a detachable connection between the connecting structure 3 and the conveying mechanism 2, providing a foundation for the subsequent transfer of the printing roller 5. When the printing roller 5 is placed on the mounting machine 4, the straight line connected to one of the connecting plates 31... The rotary motor 34 starts, and the linear rotary motor 34 drives the push rod 35 connected to it to move inward. Meanwhile, the fixed rod 36 connected to another connecting plate 31 remains fixed and does not move independently. During the inward movement of the push rod 35, it generates a pushing and squeezing force on the printing roller 5, and finally forms a clamping engagement with the fixed rod 36. The push rod 35 drives the connected printing roller 5 to rotate, ensuring that the concentricity of the connected printing roller 5 is consistent. This securely fixes all the printing rollers 5 placed on the mounting machine 4, ensuring the positional stability of the printing rollers 5 during subsequent processing.

[0024] The mounting machine 4, located at the bottom of the moving unit, is used to install the printing roller 5 in conjunction with the moving unit. The mounting machine 4 has an insertion slot 43 for accommodating the connecting plate 31. It also has a placement slot containing a lifting platform 41 that moves up and down within the slot. The lifting platform 41 has a support seat 42 for pushing the printing roller 5. The support seat 42 has a V-shaped rotating shaft to reduce friction between the support seat 42 and the printing roller 5. The mounting machine 4 also has a spray head 44 that sprays water onto the printing roller 5 for lubrication. The spray head 44 sprays liquid onto the printing roller 5 connected to the connecting structure 3 to lubricate its surface and further reduce friction. When the linear rotary motor 34 drives the push rod 35 to move, it rotates. At this point, manual correction of any bent printing roller 5 is required to ensure concentricity.

[0025] The mounting machine 4 is located at the bottom of the moving unit. Its core function is to cooperate with the moving unit to complete the installation of the printing roller 5. During operation, it first uses its own insertion slot 43 to accommodate the connecting plate 31 of the connecting structure 3, achieving precise positioning and docking between the connecting structure 3 and the mounting machine 4. After the printing roller 5 is placed in the placement slot area of ​​the mounting machine 4, the lifting platform 41 in the placement slot starts and moves upward in the placement slot. The support seat 42 with a V-shaped rotating shaft on the lifting platform 41 moves upward simultaneously and pushes the printing roller 5. The V-shaped rotating shaft structure can effectively reduce the friction between the support seat 42 and the printing roller 5. Then, the spray head 44 on the mounting machine 4 sprays water onto the printing roller 5 connected to the connecting structure 3, further reducing friction in subsequent operations through lubrication. After lubrication is completed, the linear rotary motor 34 drives the push rod 35 to move and rotate the printing roller 5. At this time, manual correction is required for the bent printing roller 5 to ensure that the concentricity of the printing roller 5 is consistent. Finally, the printing roller 5 is adapted and installed on the mounting machine 4, laying the foundation for subsequent processing.

[0026] The conveying mechanism 2 is also connected to a blocking structure 6. The blocking structure 6 is mainly used to shield the connected printing roller 5 to prevent water droplets or other materials from dripping and causing environmental pollution. The blocking structure 6 includes a drive mechanism 61 on the conveying mechanism 2. The drive mechanism 61 is a drive motor used to start the baffle 63 to move in the chute 62. The drive mechanism 61 is provided with the chute 62, and the baffle 63 is provided in the chute 62. The drive mechanism 61 drives the baffle 63 to move laterally, which is used to receive the material dripping from the printing roller 5. After the trolley 21 drives the moving plate 24 to connect with the connecting structure 3, when the printing roller 5 is moved from the mounting machine 4 to the degreasing structure 7, the driving traction chain 23 moves the moving plate 24 to the top, and after the connecting structure 3 and the printing roller 5 are separated from the mounting machine 4, the blocking structure 6 is activated, and the baffle 63 is driven to the bottom of the printing roller 5 to catch the water droplets dripping from the printing roller 5, or when the printing roller 5 is lifted out of the degreasing structure 7, the baffle 63 is used to block the material dripping from the printing roller 5 into the degreasing structure 7.

[0027] The blocking structure 6 is connected to the conveying mechanism 2. Its core function is to shield the connected printing roller 5, preventing water droplets or other materials from dripping and causing environmental pollution. It also catches any dripping materials. Its operation is precisely coordinated with the conveying mechanism 2's transfer action on the printing roller 5. When the trolley 21 drives the moving plate 24 to connect with the connecting structure 3 and moves the printing roller 5 from the mounting machine 4 to the degreasing structure 7, the blocking structure 6 is activated after the traction chain 23 moves the moving plate 24 to the top and the connecting structure 3 and printing roller 5 are completely detached from the mounting machine 4. The drive mechanism 61 drives the baffle 63 located in the slide 62 to move laterally through its own slide 62 until the baffle 63 moves precisely below the printing roller 5 to catch water droplets dripping from the surface of the printing roller 5. When the printing roller 5 completes the degreasing process and is removed from the degreasing structure 7 by the transport mechanism 2, the blocking structure 6 is activated again, and the drive mechanism 61 still drives the baffle 63 to move to the corresponding position below the printing roller 5 through the slide 62 to catch the material dripping from the degreasing structure 7 on the surface of the printing roller 5. The entire process achieves the dual functions of preventing contamination and catching materials through precise coordinated movements.

[0028] The degreasing structure 7 is located at the bottom of the moving unit and on one side of the mounting machine 4, and is used to degrease and remove copper from the printing roller 5. The degreasing structure 7 is equipped with a material inlet 71 for manually injecting the required material into it. The degreasing structure 7 also includes an automatic feeding mechanism for automatically distributing and using the injected material.

[0029] A chrome-plating structure 8 is located at the bottom of the moving unit and on one side of the degreasing structure 7, and is used for chrome plating the printing rollers 5. There are at least three chrome-plating structures 8, allowing for simultaneous chrome plating of at least three sets of printing rollers 5. All chrome-plating structures 8 are equipped with connecting pipes 91, all of which are connected to a storage box 9. The storage box 9 contains a distribution mechanism that evenly distributes the material stored in the storage box 9 to all chrome-plating structures 8.

[0030] Both the degreasing structure 7 and the chrome-plated structure 8 are provided with insertion slots 43 for inserting the connecting structure 3 and the printing roller 5 into them.

[0031] Both the degreasing structure 7 and the chrome plating structure 8 work in conjunction with the moving unit and the connecting structure 3. The degreasing structure 7, located at the bottom of the moving unit and on the same plane as the mounting machine 4, is manually injected with the required material through its own injection port 71 before operation. After injection, the automatic feeding mechanism within the degreasing structure 7 is activated, automatically distributing the injected material to the corresponding processing area. When the conveying mechanism 2 of the moving unit moves the connecting structure 3, which is connected to the printing roller 5, to the degreasing structure 7, the connecting structure 3 and the printing roller 5 are inserted into the degreasing structure 7 through the insertion slot 43. Subsequently, the degreasing structure 7 degreases and removes copper from the printing roller 5. After degreasing is completed... The conveying mechanism 2 once again drives the connecting structure 3 to detach from the degreasing structure 7 and the printing roller 5, and moves it to the chrome-plated structure 8 located on the side of the degreasing structure 7 and at the bottom of the moving unit. The insertion and positioning are completed through the insertion slot 43 on the chrome-plated structure 8. Since there are at least three chrome-plated structures 8, at least three sets of printing rollers 5 can be chrome-plated at the same time. All chrome-plated structures 8 are connected to the storage box 9 through the connecting pipe 91. After the distribution mechanism in the storage box 9 is activated, the chrome-plated material stored in the box is evenly distributed to each chrome-plated structure 8 to ensure that the printing rollers 5 in each chrome-plated structure 8 can obtain a uniform supply of chrome-plated material, and finally complete the synchronous chrome-plating of multiple sets of printing rollers 5.

[0032] When using the chrome plating system for printing rollers, the core of the system is used to remove copper and chrome plate the copper-plated printing roller 5 after copper engraving to improve its hardness. During operation, the installation machine 4 located at the bottom of the moving unit first assists the moving unit in completing the initial installation of the printing roller 5. The installation machine 4 achieves precise positioning by accommodating the connecting plate 31 of the connecting structure 3 through its own insertion slot 43. After the printing roller 5 is placed in the placement slot area, the lifting platform 41 in the placement slot drives the support seat 42, which is set with a V-shaped rotating shaft, to move upward and push the printing roller 5. The V-shaped rotating shaft reduces friction. Then, the spray head 44 of the installation machine 4 sprays water onto the printing roller 5 for lubrication. After lubrication is completed, the linear rotary motor 34 connected to the connecting plate 31 in the connecting structure 3 starts and drives the roller. The push rod 35 moves inward, forming a clamping fit with the fixing rod 36 fixed on the other connecting plate 31 to fix all the printing rollers 5. At the same time, the linear rotary motor 34 drives the printing rollers 5 to rotate. The bending parts are manually corrected to ensure concentricity. The two connecting plates 31 are fixed by the connecting rod 33, and the snap-fit ​​connector 32 on their outer side is used to connect with the conveying mechanism 2. Then the moving unit starts. The slide rail 11 of the crane frame 1 defines the trajectory of the conveying mechanism 2. The built-in driver of the crane 21 drives itself to move along the slide rail 11. At the same time, the traction chain 23 drives the moving plate 24 to move. The limit plate 22 at the bottom of the crane 21 ensures that the moving plate 24 moves vertically and drives the hook plate 25 connected to the connecting shaft 26 to move down. The hook plate 25 is subjected to The clamp connector 32 blocks the connection shaft 26, which rotates and folds through the clamp connector 32 to its lower position. Then, the moving plate 24 moves upward. The hook plate 25, limited by its own width and connection position, cannot rotate downward. Thus, the hook connector 32 drives the connecting structure 3 and the printing roller 5 to move upward. When the trolley 21 drives the moving plate 24 to the top via the traction chain 23, and the connecting structure 3 and the printing roller 5 are separated from the installation machine 4, the blocking structure 6 on the transport mechanism 2 is activated. The drive mechanism 61 drives the motor to drive the baffle 63 to move laterally to the lower position of the printing roller 5 via the slide 62 to collect the dripping water droplets. Then, the transport mechanism 2 drives the printing roller 5 to the degreasing structure 7 located on the same plane as the installation machine 4, at the bottom of the moving unit. The degreasing structure 7... The insertion slot 43 completes the insertion. Before degreasing, the material is manually injected through the injection port 71. The internal automatic feeding mechanism automatically distributes the material. After degreasing and copper removal, the conveying mechanism 2 drives the printing roller 5 to detach from the degreasing structure 7. The blocking structure 6 restarts to receive the dripping degreasing material. Finally, the conveying mechanism 2 moves the printing roller 5 to the chrome-plated structure 8 at the bottom of the moving unit on one side of the degreasing structure 7. It is inserted and positioned through the insertion slot 43 of the chrome-plated structure 8. At least three chrome-plated structures 8 can process multiple sets of printing rollers 5 simultaneously. All chrome-plated structures 8 are connected to the storage box 9 through the connecting pipe 91. The distribution mechanism in the storage box 9 distributes the chrome-plated material evenly to each chrome-plated structure 8, and finally completes the synchronous chrome plating processing of multiple sets of printing rollers 5.
