Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a cylindrical packaging device for imitation leather texture roll packaging. Background Technology

[0002] Simulated PU leather is a type of artificial leather. Because it is made of polyurethane, it is simply called simulated PU leather. Existing imitation leather textured rolls are usually packaged in compatible packaging tubes for easy storage and transportation.

[0003] A search revealed a patent document with publication number "CN208666050U" that discloses a packaging tube for a film roll, comprising a tube body open at least one end, with a cover at one end of the tube body; the cover includes an insertion part for inserting into the hollow portion of the roll material and a locking part for engaging with the tube body; the insertion part is a cylindrical body closed at one end and open at the other; the locking part includes an upper cover plate, an inner ring and an outer ring disposed at the edge of the upper cover plate; the side wall of the tube body is inserted between the inner ring and the outer ring; the insertion part and the upper cover plate are connected by a connecting tube.

[0004] The aforementioned packaging tubes may also be used in the packaging of imitation leather texture rolls. Based on the above search and combined with existing technology, it was found that although existing packaging devices are convenient for packaging rolls (such as imitation leather texture rolls), they are inconvenient to use. For example, when packaging shorter imitation leather texture rolls, there will be a large gap inside the packaging device, and the shorter imitation leather texture rolls will move back and forth inside the packaging device, generating friction and impact that will damage the imitation leather texture rolls. On the other hand, longer imitation leather texture rolls cannot be packaged, which is inconvenient to use. Therefore, a cylindrical packaging device for packaging imitation leather texture rolls is needed. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0030] Example: Reference Figures 1-4 The illustrated cylindrical packaging device for imitation leather textured roll packaging includes a first cylindrical body 1, a second cylindrical body 2, a third cylindrical body 3, a cylindrical cover 4, and fastening bolts 5;

[0031] The first cylinder 1 is a cylinder with one end closed, and the second cylinder 2 is a cylinder with both ends open. The inner and outer diameters of the second cylinder 2 are the same as those of the first cylinder 1. An annular receiving groove is provided on the side of the first cylinder 1 and the second cylinder 2 that are close to each other.

[0032] The third cylinder 3 is a cylinder with openings at both ends. The two ends of the third cylinder 3 are slidably connected to the annular receiving grooves of the first cylinder 1 and the second cylinder 2, respectively. The cylinder cover 4 is closed on the end of the second cylinder 2 away from the first cylinder 1, and the cylinder cover 4 and the second cylinder 2 are detachably fixed.

[0033] Multiple fastening bolts 5 are provided, and the multiple fastening bolts 5 are respectively screwed to the outer side of the first cylinder 1 and the second cylinder 2 that are close to each other. One end of the fastening bolt 5 extends into the annular receiving groove and is interference-fitted with the outer wall of the third cylinder 3.

[0034] Based on the above structure, during use, the operator can adjust the overall length of the cylindrical packaging device for the imitation leather texture roll material by stretching the first cylinder 1 and the second cylinder 2 to make the exposed part of the third cylinder 3 longer or shorter. After adjustment, simply tighten the fastening bolt 5 so that one end of the fastening bolt 5 is interference-fitted with the outer wall of the third cylinder 3, thereby fixing both ends of the third cylinder 3 to the first cylinder 1 and the second cylinder 2, forming a cylindrical packaging device of fixed length. This can be used to meet the packaging needs of imitation leather texture roll materials of different lengths, and can avoid the disadvantages of shorter imitation leather texture roll materials moving back and forth inside the cylindrical packaging device and causing damage, or longer imitation leather texture roll materials being unable to be packaged, making it more flexible and convenient to use.

[0035] Furthermore, both the first cylinder 1 and the second cylinder 2 are equipped with arc-shaped retaining plates 6. Taking the arc-shaped retaining plate 6 installed in the first cylinder 1 as an example: the arc-shaped retaining plate 6 is an arc-shaped plate adapted to the curved surface of the inner wall of the first cylinder 1. A spring 61 is fixed on the side of the arc-shaped retaining plate 6 close to the inner wall of the first cylinder 1, and the end of the spring 61 away from the arc-shaped retaining plate 6 is fixed to the inner wall of the first cylinder 1.

[0036] It should be noted that the installation method of the arc-shaped clamping plate 6 inside the second cylinder 2 is the same as that inside the first cylinder 1.

[0037] By using the arc-shaped clamping plate 6 and the spring 61, the arc-shaped clamping plate 6 can elastically clamp the periphery of the placed imitation leather texture roll material, and can clamp imitation leather texture roll materials of different outer diameters, further improving the applicability of the cylindrical packaging device for imitation leather texture roll material packaging, thereby further improving the flexibility of the cylindrical packaging device for imitation leather texture roll material packaging during use.

[0038] Furthermore, both ends of the arc-shaped retaining plate 6 are integrally formed with flared edges 62. The flared edges 62 extend outward at an angle away from the axis of the first cylinder 1. The flared edges 62 are also arc-shaped plates. Through the setting of the flared edges 62, the imitation leather texture roll material is guided to maintain its stable posture during the insertion and removal process, thereby facilitating the insertion and removal of the imitation leather texture roll material and making it more convenient and faster to use or store the imitation leather texture roll material.

[0039] Furthermore, a central positioning protrusion 11 is formed on the inner side wall of the end of the first cylinder 1 away from the second cylinder 2. The front end of the central positioning protrusion 11 is chamfered. The central positioning protrusion 11 is inserted into the hollow shaft in the middle of the imitation leather texture roll. The central positioning protrusion 11 can be used to axially position the imitation leather texture roll, ensuring that the imitation leather texture roll is always in the middle position after being placed, thereby avoiding radial movement.

[0040] The cap 4 and the first cylinder 1 are both provided with grooves 9 on the sides that are far apart from each other. The grooves 9 make it easy for workers to hold the cylindrical packaging device of the imitation leather texture roll packaging, or to use transport machinery to lift and move the cylindrical packaging device of the imitation leather texture roll packaging, so as to facilitate the movement and transportation after packaging.

[0041] Furthermore, a threaded groove 21 is provided on the outer side of the end of the second cylinder 2 away from the first cylinder 1, and a threaded part 41 is formed on the inner side of the cylinder cover 4 to be threaded and adapted to the threaded groove 21.

[0042] Both the outer sides of the first cylinder 1 and the second cylinder 2 are provided with stepped holes 8 for fastening bolts 5 to be screwed in, and the fastening bolts 5 are threaded to the stepped holes 8.

[0043] A groove 7 is provided on the outer wall of the annular receiving groove away from the central axis of the first cylinder 1. The end of the groove 7 extends to the inner side of the opening of the annular receiving groove. Limiting sliders 31 are fixed on the outer walls of both ends of the third cylinder 3. The limiting sliders 31 are slidably embedded in the groove 7. Through the cooperation of the groove 7 and the limiting sliders 31, the third cylinder 3 is more stable during the sliding process. At the same time, it can limit the relative sliding distance between the third cylinder 3 and the first cylinder 1 and the second cylinder 2, so as to prevent the third cylinder 3 from falling off the first cylinder 1 or the second cylinder 2, and ensure the structural integrity of the cylindrical packaging device of the imitation leather texture roll packaging when adjusting the length.

[0044] The working principle of this utility model is as follows: In daily use, the operator can stretch the first cylinder 1 and the second cylinder 2 to make the exposed part of the third cylinder 3 longer or shorter, thereby adjusting the overall length of the cylindrical packaging device for the imitation leather texture roll material. After adjustment, simply tighten the fastening bolt 5 so that one end of the fastening bolt 5 is interference-fitted with the outer wall of the third cylinder 3, thereby fixing both ends of the third cylinder 3 to the first cylinder 1 and the second cylinder 2, forming a cylindrical packaging device of fixed length. This can be used to meet the packaging needs of imitation leather texture roll materials of different lengths, and can avoid the disadvantages of shorter imitation leather texture roll materials moving back and forth inside the cylindrical packaging device and causing damage, or longer imitation leather texture roll materials being unable to be packaged, making it more flexible and convenient to use.

[0045] In addition, the curved clamping plate 6 can elastically hold the periphery of the placed imitation leather texture roll material and can hold imitation leather texture roll materials of different outer diameters, further improving the applicability of the cylindrical packaging device for imitation leather texture roll material packaging, thereby further improving the flexibility of the cylindrical packaging device for imitation leather texture roll material packaging during use.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
