Description

Technical Field

[0001] The utility model relates to the technical field of embossing, and particularly relates to a rubber roll grinding device. Background Art

[0002] Embossing technology and printing technology are often used in the decorative processing of coils and sheets. For example, embossing treatment is required during the processing of cigarette packet inner lining paper. An embossing device generally includes a rigid embossing roll engraved with concave and convex patterns and an elastic and smooth-surfaced wool roll. The product passes through between the embossing roll and the wool roll, and the embossing roll and the wool roll apply pressure to the product from both sides, so that the concave and convex patterns on the embossing roll are imprinted on the product.

[0003] After an embossing device is used for a period of time, due to the long-term extrusion between the embossing roll and the wool roll, the concave and convex patterns on the embossing roll will act on the wool roll to a certain extent, making the surface of the wool roll uneven, thereby affecting the subsequent embossing effect of the product. At this time, the wool roll needs to be polished. In traditional methods, a scraper and sandpaper are generally used for manual grinding of the wool roll. The grinding efficiency and effect depend on the proficiency and skill level of the operator, and the problem of uneven grinding is likely to occur. The patent document with the application number CN201821257929.2 discloses a wool roll grinding device, which includes lifting mechanisms arranged on both sides of the wool roll. A horizontal movement device is fixed on the lifting mechanism, and a grinding piece is installed under the component that makes horizontal movement in the horizontal movement device. The grinding piece generates frictional force with the wool roll by the action of the lifting mechanism, and the grinding piece moves along the axial direction of the wool roll through the horizontal movement device to realize the grinding and polishing of the wool roll. In the above solution, the magnitude of the frictional force between the wool roll and the grinding piece is controlled by the lifting mechanism, and the adjustment accuracy of the frictional force is low, which is likely to affect the grinding effect. In order to improve the adjustment accuracy, a pressure sensor and a background control system can be additionally equipped, but this will result in a higher equipment cost and additional space occupation.

Embodiment

[0028] Refer to Figure 1 and Figure 2, an embodiment of the first aspect of the present utility model provides a wool roller grinding device, which includes a lifting mechanism 1, a horizontal movement mechanism 2, a fine adjustment mechanism 3 and a grinding member 4; the lifting mechanism includes a first driving member 11 and a driving rod 12 controlled by the first driving member, the driving rod is a lead screw, and the driving rod can rotate around the axis under the control of the first driving member; the horizontal movement mechanism includes an adjustment base 21, a second driving member 22 and an adjustment substrate 23, the adjustment base 21 has a mating portion 211 threadedly connected to the driving rod 12, when the driving rod rotates, the adjustment base moves linearly along the axial direction of the driving rod, a convex guide rail 212 extending in the horizontal direction is provided on the adjustment base, the second driving member 22 has a rotatable roller 221, a guide groove 231 slidably matched with the guide rail 212 is provided on the first side of the adjustment substrate 23, and a horizontally extending mounting plate 232 is provided on the second side, the adjustment substrate 23 can slide horizontally relative to the adjustment base 21, the cylinder body of the second driving member 22 is fixedly connected to the adjustment substrate, and the roller 221 can roll along the adjustment base in the horizontal direction, so as to drive the adjustment substrate to move in the horizontal direction. The roller and the adjustment base can roll by means of friction or by means of gear meshing; the fine adjustment mechanism includes an adjustment screw 31, an adjustment block 32 and a guide rod 33, a positioning hole 233 is provided in the middle of the mounting plate 232, a limiting portion 234 is provided at the upper side position of the positioning hole, the adjustment screw passes through the positioning hole movably, a control handle 311 is provided at the upper end of the adjustment screw, and a clamping portion 312 movably matched with the limiting portion 234 is provided in the middle of the adjustment screw. The clamping portion makes the adjustment screw unable to move axially but can rotate around the axis. A part of the adjustment screw near the lower end forms an external thread. The upper end of the guide rod 33 is perpendicularly and fixedly connected to the mounting plate 232, and a limiting end 331 is formed at the lower end of the guide rod. A connecting screw hole 321 threadedly matched with the adjustment screw is formed in the middle of the adjustment block 32. The guide rod 33 passes through the adjustment block and enables the adjustment block to slide along the guide rod. The grinding member is connected to the lower end of the adjustment block.

[0029] The working principle of the present utility model is as follows: First, the first driving member 11 controls the driving rod 12 to rotate, so that the adjustment base 21 moves up and down along the driving rod, adjusting the distance between the grinding member and the wool roller to be ground. After the distance adjustment is completed, the adjustment screw 31 is rotated by the control handle 311. Under the action of the adjustment screw, the adjustment block 32 gradually moves downward until a certain pressure is formed between the adjustment block and the wool roller. Then, the rotation motor is started to make the wool roller and the grinding member rotate relative to each other, that is, the grinding starts. During the grinding process, the second driving member 22 makes the grinding member gradually move along the axial direction of the wool roller to ensure that each area of the wool roller is evenly ground, that is, the grinding and polishing treatment of the wool roller is completed.

[0030] Figure 3The structural schematic diagram of the fine-tuning mechanism in another embodiment is shown. The fine-tuning mechanism includes an adjusting screw 31, an adjusting block 32, and a guiding rod 33. A positioning hole 233 with internal threads is provided in the middle of the mounting plate 232. The adjusting screw movably passes through the positioning hole. A control handle 311 is provided at the upper end of the adjusting screw. External threads that cooperate with the positioning hole are provided in the middle of the adjusting screw. The lower end of the adjusting screw abuts against the adjusting block 32. The upper end of the guiding rod 33 is perpendicularly and fixedly connected to the mounting plate 232. The guiding rod passes through the adjusting block and enables the adjusting block to slide along the guiding rod. When the adjusting screw rotates, it will vertically move relative to the mounting plate, changing the abutting pressure with the lower adjusting block 32, thereby adjusting the frictional force.

[0031] Figure 4 The structural schematic diagram of the fine-tuning mechanism in another embodiment is shown. In this embodiment, the adjusting block 32 is divided into an upper movable block 322 and a lower movable block 323 that are arranged at intervals. Both the upper movable block and the lower movable block are slidably connected to the guiding rod. The lower end of the adjusting screw is connected to the upper movable block, and the grinding member is connected to the lower movable block. An elastic element 324 is provided between the upper movable block and the lower movable block. The upper and lower ends of the elastic element 324 respectively abut against the upper movable block and the lower movable block. When the adjusting screw is rotated, the upper movable block moves downward and squeezes the elastic element, thereby applying pressure to the lower movable block through the elastic element to increase the frictional force, and vice versa to reduce the frictional force. Figure 4 In the shown embodiment, the elastic element is a spring sleeved on the guiding rod. In some other embodiments, the elastic element can also be directly arranged at the middle position of the adjusting block and connect the upper movable block and the lower movable block. At the same time, other materials with elastic recovery ability, such as rubber, can also be selected as the elastic element. Figure 5 Another installation structure of the guiding rod in the fine-tuning mechanism is shown. The lower end of the guiding rod is fixedly connected to the lower movable block, and the upper end movably passes through the mounting plate. When the lower movable block moves up and down, it drives the guiding rod to move together.

[0032] The above-mentioned lifting mechanism and horizontal movement mechanism can also achieve the lifting and horizontal movement of the grinding member through other principles. For example, in some embodiments, the driving rod of the lifting mechanism is a telescopic vertical air rod, and the adjusting base is connected to the vertical air rod. Similarly, the second driving mechanism is connected to a telescopic horizontal air rod, and the adjusting substrate is connected to the horizontal air rod.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
