Description

Technical Field

[0001] The utility model relates to the field of printing, in particular to a mounting assembly of an ink shielding plate. Background Art

[0002] Gravure printing is based on the principle that the image part of the printing plate is lower than the blank part. During the printing process, the entire surface of the plate roller is covered with ink, and then a special scraping mechanism, such as a scraper, removes the ink from the blank part, leaving only the ink on the image part. Then, under a greater pressure, the ink on the image part is transferred to the surface of the substrate to complete the printing.

[0003] During the printing process, the plate roller is located in an ink tank filled with printing dye. As the plate roller rotates at high speed, it continuously stains the ink and prints. During the rotation of the plate roller, the ink splashes seriously due to the centrifugal force. Therefore, an ink shield needs to be set up to prevent the ink from polluting the workshop.

[0004] For example, in the Chinese patent with the authorization announcement number CN 218986108 U, the scraper is detachably mounted on the ink tank body, and the lower baffle is mounted on the bottom of the scraper. The scraper is removed from the ink tank to achieve the removal of the lower baffle. During the printing process, the continuous friction between the scraper and the plate roller will cause wear, while the lower baffle does not have friction contact with the plate roller. Therefore, the service life and replacement cycle of the scraper and the plate roller are different. If one of the scraper and the baffle is damaged, they are replaced at the same time, which results in a large consumption of resources.

[0005] In addition, if the printing color or printing pattern needs to be changed in the printing production line, it is usually necessary to replace the ink or the plate roller, and the ink tank needs to be disassembled and cleaned. This structure makes it inconvenient to disassemble the lower scraper and the scraper for cleaning, resulting in low production efficiency. In addition, the positional relationship between the lower scraper and the scraper is fixed. When the size of the plate roller is changed, the positional relationship between the scraper and the plate roller, and the scraper and the plate roller cannot be satisfied at the same time. It is necessary to configure scrapers and scrapers of various sizes to meet production needs, which makes the production cost high. Utility Model Content

[0006] The utility model aims to provide a mounting assembly for an ink shield plate, so as to solve the technical problem in the prior art that the ink shield plate is not convenient to be disassembled independently.

[0007] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an installation assembly of an ink shield plate, comprising an ink shield plate and a shield fixing component, the shield fixing component removably fixes the ink shield plate to a mounting surface, the shield fixing component comprises a bolt, a pressure plate and a compression spring, the pressure plate is provided with a through hole, the mounting surface is provided with an internal threaded hole, the bolt is a screw rod passing through the through hole of the pressure plate and threadedly connected with the internal threaded hole of the mounting surface, the compression spring is wound on the screw rod of the bolt, and the compression spring is located between the head of the bolt and the pressure plate in a compressed state; one end of the ink shield plate is clamped and fixed between the mounting surface and the pressure plate.

[0008] The principle and advantages of this scheme are as follows: in actual application, the pressure plate is pulled close to the head of the bolt, the compression spring is compressed, the distance between the pressure plate and the mounting surface is increased, one end of the ink shield is placed between the pressure plate and the mounting surface, the pressure plate is released, the compression spring is expanded, the pressure plate is pressed against the mounting surface again, and the position of the ink shield on the mounting surface is fixed; when the ink shield needs to be removed, the ink shield can be directly pulled outward by external force; the separate removal of the ink shield is realized;

[0009] The baffle fixing component makes the ink baffle easy to clean and maintain, improves equipment maintenance efficiency, speeds up ink baffle replacement, and reduces production losses caused by downtime for component replacement; convenient disassembly also reduces the difficulty of maintenance personnel's work, and ordinary workers can also complete it, reducing maintenance costs. The pressure plate and the mounting surface can clamp ink baffles of various thicknesses, which also improves the flexibility and adaptability of the equipment.

[0010] As an improvement, the pressing plate includes an integrally formed pressing surface and a lifting portion, one end of the lifting portion is arranged at the middle section of the pressing surface, and the pressing surface and the lifting portion are T-shaped.

[0011] The beneficial effect of this improvement is that the pressing surface and the lifting part are T-shaped, which makes it easy for the operator to hold the lifting part and move the pressing plate, making the operation more convenient.

[0012] As an improvement, one end of the lifting portion away from the pressing surface is tilted away from the mounting surface.

[0013] The beneficial effect of this improvement is that a gap is left between the lifting portion and the mounting surface to facilitate the operator to hold the device.

[0014] As an improvement, the pressing surface is a long rectangular surface, and the length of the pressing surface is greater than the width of the ink baffle.

[0015] The beneficial effect of this improvement is that the pressing surface is in the shape of a long strip, so that the ink shielding plate can be adjusted in position along the length direction of the pressing surface, and can adapt to plate rollers of different lengths.

[0016] As an improvement, the single pressing plate is fixed by two groups of the bolts and the compression springs, and the fixing points of the pressing plate and the mounting surface are located at both ends of the pressing plate.

[0017] The beneficial effect of this improvement is that the bolts and the compression springs are fixed at both ends of the pressure plate, making the pressure plate installation more stable.

[0018] As an improvement, the ink shield covers the plate roller and is installed at both ends of the plate roller.

[0019] The beneficial effect of this improvement is that the thin sheet-like ink shield is relatively light and can be stably clamped by the shield fixing component, and the other end of the ink shield is in a relatively free state and can lightly cover the end of the plate roller without affecting the normal operation of the plate roller.

[0020] As an improvement, the ink shielding plate is a metal plate or a polymer material plate.

[0021] The beneficial effect of this improvement is that the ink shield has a certain support and flexibility, and within the elastic deformation range, the ink shield can return to its original shape after the external force is removed. BRIEF DESCRIPTION OF THE DRAWINGS

The end of the lifting part away from the pressure surface tilts away from the mounting surface. The two ends of the pressure plate 9 are fixed to the mounting surface by two groups of bolts 7 and the clamping spring 8 respectively.

[0033] The mounting plate 3 is provided with an extension surface extending toward the ink tank 1 at one end close to the scraper 4, and the bolts 7 of the baffle fixing member for mounting the lower baffle 6 fix the pressing plate 9 on the extension surface, and one end of the lower baffle 6 is clamped between the pressing plate 9 and the extension surface; the bolts 7 of the baffle fixing member for mounting the upper baffle 5 fix the pressing plate 9 on the scraper 4, and one end of the upper baffle 5 is clamped between the pressing plate 9 and the scraper 4.

[0034] The ink outlets in the ink tank 1 are located at the two ends of the plate roller 2, so the lower baffle 6 and the upper baffle 5 are two pieces, and are respectively installed at the two ends of the plate roller 2.

[0035] As attached Figure 4 As shown, the scraper 4 fixing component includes a fixing seat 10, a fixing block 11 and a locking piece 12.

The rear end face is parallel to the front end face but relatively backward, forming a staggered parallel relationship. The front end face and the rear end face are connected by a folded surface, and the folded surface is inclined at a certain angle to the horizontal plane; the front end face of the fixing block 11 is fixed to the scraper 4 by bolts, and the rear end face of the fixing block 11 is provided with a strip hole, which is an open hole, and one side of the strip hole is open without an edge and is directly connected to the edge of the rear end face. The locking piece 12 is in the shape of a bolt, and the head of the locking piece 12 is in the shape of a disc tangent to the rear end face of the fixing block 11.

[0036] Four fixing blocks 11 are evenly spaced on the scraper 4, and two fixing seats 10 and a locking member 12 are provided on the mounting plate 3. Any two adjacent fixing blocks 11 on the scraper 4 can be assembled with the fixing seats 10 on the mounting plate 3 to adjust the relative position of the scraper 4 and the mounting plate 3.

[0039] The specific implementation process is as follows:

[0040] When the ink blocking device is adjusted and put into use, the mounting plate 3 is in a vertically upward state, the strip hole opening of the fixed block 11 on the scraper 4 is aligned with the locking member 12 and inserted, and the locking member 12 is rotated to fix the scraper on the mounting plate 3, and then the pressing plate 9 on the extension is lifted to fix the lower baffle 6 on the mounting plate 3, and the rotating shaft 16 is driven to rotate 90° to extend the lower baffle 6 into the ink tank 1, and the screw rod 13 is driven to rotate to make the mounting plate 3 approach the plate roller 2 until the scraper 4 contacts the peripheral surface of the plate roller 2, and then the pressing plate 9 on the scraper 4 is lifted to fix the upper baffle 5 on the scraper 4. The upper baffle 5 and the lower baffle 6 are formed to cover the upper and lower parts of the plate roller 2 respectively.

[0041] As attached Figure 1 As shown in the figure, when the plate roller 2 is immersed in the ink and rotates clockwise at a high speed, the circumference of the plate roller 2 presses over the ink liquid surface, generating a shearing effect on the liquid surface, so that the ink moves rapidly to both sides under the pressure of the plate roller 2, and splashes out along the circumferential edges on both sides of the plate roller 2, forming axial water splashes at the end of the plate roller 2. The splashed ink will contaminate the dyed cloth to be processed and the entire printing workshop.

[0042] The rotation of the ink plate roller 2 below the plate roller 2 forms a vortex, so that part of the ink is brought out of the liquid surface with the rotation, and the setting of the lower baffle 6 can block the formation of part of the vortex below the plate roller 2, reduce the ink splashed with the rotation of the plate roller 2, and reduce the scraping pressure of the scraper 4. Furthermore, the upper baffle 5 further blocks a small part of the splashed ink, thereby achieving comprehensive blocking of the ink.

[0043] Example 2

[0044] On the basis of Example 1, the upper baffle 5 and the lower baffle 6 are thin sheets made of metal or polymer materials, so that the upper baffle 5 and the lower baffle 6 have certain support and flexibility. In addition, within the elastic deformation range, the upper baffle 5 and the lower baffle 6 can return to their original shapes after the external force is removed. The metal material can be aluminum alloy and stainless steel, etc., and the polymer material can be polyurethane, etc.

[0045] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
