Technical Field
[0001] This utility model relates to the field of packaging bag processing technology, and in particular to a packaging bag surface embossing device. Background Technology
[0002] Plastic bags are a widely used packaging material, made primarily of plastic, and are commonly used for packaging various items in daily life and industrial production. They are popular due to their lightweight, waterproof, moisture-proof, and durable properties.
[0003] For example, the patent entitled "An Embossing Device for Plastic Packaging Bag Production" (patent application number: CN202421338127.X) discloses an embossing device for plastic packaging bag production. This device involves inserting a plastic roll into the outer wall of a rotating roller, then moving the roll along the roller's path until it reaches a suitable position. A sliding block is then placed inside a groove, and the block is slid until it contacts one end of the plastic roll. Next, limiting sleeves one and two are rotated to engage, thus fixing the plastic roll relative to the rotating roller. This device can effectively limit and fix plastic rolls of different sizes. However, in actual use, this embossing device is only suitable for plastic rolls with a single inner diameter. When a larger inner diameter plastic roll is used, it is prone to shaking, affecting the embossing quality, and its efficiency needs improvement.
[0004] Therefore, it is necessary to propose a packaging bag surface embossing device to solve the above problems. Utility Model Content

[0026] This utility model provides, for example Figures 1-6 The illustrated packaging bag surface embossing device includes a workbench 1, with an embossing machine 2 mounted on top of the workbench 1 and connected to the factory's power supply.
[0027] Embossing machine 2 includes a mold part, a heating system part, and other structures.
[0028] The mold part includes a textured embossing roller and a matching roller. The texture on the surface of the embossing roller is designed according to the pattern to be pressed. The roller is used to work with the embossing roller to apply pressure to the plastic bag material, so that the texture can be clearly printed on the plastic bag. The mold is generally made of metal, such as copper or steel.
[0029] In the heating system section, since plastic materials are relatively hard at room temperature and not easy to shape, a heating system is needed to soften the plastic bag material so that it is easier to shape during the embossing process. It generally includes heating elements such as electric heating plates and electric heating tubes, as well as temperature control components such as temperature sensors and temperature controllers.
[0030] The embossing machine 2 and its working principle are common existing technologies, and will not be elaborated here.
[0031] A rotating drum 4 is installed above the workbench 1, and a vertical plate 3 is installed on the top of the workbench 1. The rotating drum 4 is rotatably connected to the vertical plate 3, and the packaging bag roll is fitted on the outside of the rotating drum 4.
[0032] Considering the varying inner diameters of packaging bag rolls, and to improve the applicability of the packaging bag surface embossing device, a sliding column 5 is installed inside the rotating drum 4. A square groove 7 is provided on the outer wall of the rotating drum 4. Multiple square grooves 7 are provided and evenly distributed around the rotating drum 4. A block 8 is slidably installed inside the square groove 7. An arc strip 9 is fixedly connected to one end of the block 8 located outside the rotating drum 4. The side of the arc strip 9 closest to the block 8 is a concave side.
[0033] The outer wall of the sliding column 5 is provided with side grooves 6 corresponding to the blocks 8. The ear plate 10 is slidably arranged inside the side groove 6. The inner wall of the side groove 6 is provided with a sliding groove 11. The sliding groove 11 is inclined. The slider 12 is slidably arranged inside the sliding groove 11. The slider 12 is fixedly connected to the ear plate 10.
[0034] In actual use, ball bearings can be installed between the ear plate 10 and the inner wall of the side groove 6, between the slider 12 and the inner wall of the slide groove 11, and other positions where necessary, to ensure smooth sliding and prevent jamming.
[0035] The rotating drum 4 is provided with an adjustment assembly for driving the sliding column 5 to move along the axial direction of the rotating drum 4. The adjustment assembly consists of a threaded cylinder 15 and a threaded rod 16. The threaded cylinder 15 is fixedly connected to the sliding column 5, and the threaded rod 16 is rotatably connected to the rotating drum 4. The threaded rod 16 is threadedly connected to the threaded cylinder 15.
[0036] The coefficient of friction between the threaded rod 16 and the threaded cylinder 15 is suitable, and the threaded rod 16 will not rotate arbitrarily.
[0037] A cylinder 13 is fixedly connected to the end of the sliding column 5 away from the threaded cylinder 15. A fixing rod 14 is slidably installed inside the cylinder 13 and is fixedly connected to the inner wall of the rotating cylinder 4. The cylinder 13 and the fixing rod 14 are provided to ensure the stability of the sliding column 5 during use, and the upright plate 3 is close to the fixing rod 14.
[0038] The sliding column 5, the cylindrical column 13, the threaded cylinder 15, and the rotating cylinder 4 are all arranged concentrically.
[0039] Reference Figure 4 As shown, the right side of the slide 11 is inclined upward.
[0040] In use, the packaging bag roll is inserted into the outside of the multiple arc strips 9 to form a cylindrical structure. The threaded rod 16 is rotated. Since the threaded rod 16 is threadedly connected to the threaded cylinder 15, the sliding column 5 moves to the left under the limiting cooperation of the square block 8, the square block 8 extends outward of the rotating cylinder 4, and the arc strips 9 are pressed against the inner wall of the packaging bag roll to achieve the compression and positioning of the packaging bag roll, so that the packaging bag roll will not shake at will and the stability of the embossing process is guaranteed.
[0041] Since the extension length of block 8 is adjustable, it is suitable for packaging bag rolls with different inner diameters, thus improving the applicability of the packaging bag surface embossing device.
[0042] This invention achieves compression positioning of the packaging bag roll by setting up a rotating drum 4, a sliding column 5, a block 8, and an adjustment component, so that the packaging bag roll will not shake randomly, ensuring the stability of the embossing process, and is applicable to packaging bag rolls with different inner diameters, thus improving the applicability of the packaging bag surface embossing device.
[0043] To prevent the packaging bag roll from slipping off the adjusting component, multiple insertion holes 17 are provided on the outer wall of the rotating drum 4. The insertion holes 17 correspond to the threaded rods 16. An insertion rod 18 is inserted into one of the insertion holes 17 and abuts against the threaded rod 16. A rubber sleeve 19 is fixedly connected to the insertion rod 18. The rubber sleeve 19 is made of rubber and multiple insertion rods 18 can be prepared for easy replacement.
[0044] During use, the insertion rod 18 will not come into contact with the workbench 1.
[0045] After the packaging bag roll is fitted onto the outside of the multiple arc strips 9 to form a cylindrical structure and the packaging bag roll is squeezed and positioned, the insert rod 18 is inserted into the corresponding insertion hole 17. The rubber sleeve 19 passes through the insertion hole 17 and abuts against the inner wall of the rotating drum 4. The insert rod 18 will not fall off at will, thus limiting the packaging bag roll. The insertion hole 17 is provided with multiple holes, which are suitable for packaging bag rolls of various axial lengths. At the same time, the insert rod 18 abuts against the threaded rod 16, providing a certain frictional resistance for the rotation of the threaded rod 16, further reducing the probability of the threaded rod 16 rotating at will.
[0046] When it is necessary to reverse the rotation of the threaded rod 16, simply pull out the insert rod 18 first.
