Description

Technical Field

[0001] The utility model relates to the technical field of tire packaging, and more specifically, to a packaging film quick-changing system. Background Art

[0002] After the production of various products is completed, they need to be packaged. For large items, most of them are packaged by packaging film, tape or packaging rope.

[0003] Automobile tires are one of the important parts of automobiles. They are in direct contact with the road surface and work together with the automobile suspension to mitigate the impact of the car when it is driving. Whether it is a semi-steel tire, a full-steel tire or a special tire, the tire needs to be packaged after production. When packaging, the packaging film is passed through the inner hole of the tire and then wrapped around the tire. The tire is packaged through multiple turns of winding.

[0004] When packaging automobile tires, the packaging film is set in a roll. The packaging film needs to be installed on the tire packaging equipment, and the packaging film is unrolled by rotating the packaging film, so as to wrap the packaging film around the tire. When installing the packaging film roll, the packaging film roll is put on the cylinder of the packaging equipment, and then a baffle is screwed on the cylinder by threaded connection. The baffle prevents the packaging film roll from sliding off the cylinder. This installation method requires frequent unscrewing and installing of the baffle when replacing the packaging film roll, making the operation cumbersome and inconvenient. Utility Model Content

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should all fall within the scope of protection of this application. In addition, the directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only referenced to the directions of the drawings. Therefore, the directional words used are used to illustrate rather than limit the invention.

[0027] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0028] Embodiment: A packaging film quick change system, see attached Figure 1 -Attached Figure 4, comprising a fixed column 1 detachably connected to the tire packaging equipment, a rotating column 2 sleeved outside the fixed column 1 and rotatably connected to the fixed column 1, a plurality of expansion pieces 3 arranged around the rotating column 2, and a plurality of elastic members 8 arranged on the rotating column 2. The length direction of the expansion piece 3 is arranged along the axial direction of the rotating column 2, and the plurality of expansion pieces 3 are evenly arranged around the axis of the rotating column 2. The side of the expansion piece 3 close to the rotating column 2 is embedded in the rotating column 2 and can slide in the rotating column 2 along the radial direction of the rotating column 2. Each expansion piece 3 corresponds to at least one elastic member 8. When the packaging film roll is sleeved outside the rotating column 2 and contacts the side of the plurality of expansion pieces 3 away from the rotating column 2, the elastic member 8 is squeezed and applies an elastic force to the expansion piece 3 away from the axis of the rotating column 2.

[0029] When the packaging film roll is installed outside the rotating column 2, the packaging film roll pushes the expansion piece 3 to slide in the direction close to the axis of the rotating column 2, so that the expansion piece 3 squeezes the elastic member 8. When the packaging film roll is completely sleeved on the outside of the rotating column 2, under the action of the elastic member 8, multiple expansion pieces 3 are simultaneously pressed against the inner side of the packaging film roll under the action of the elastic member 8, so that the packaging film roll is limited outside the rotating column 2.

[0034] Specifically, a limiting ring 6 is provided on the outer sleeve of the fixed column 1, and the limiting ring 6 is arranged between the retaining ring 4 and the tire packaging equipment; the end of the fixed column 1 away from the limiting ring 6 is detachably connected with a pressure ring 7, and the pressure ring 7 and the limiting ring 6 limit the retaining ring 4, the rotating column 2 and the fixed ring 5 between the pressure ring 7 and the limiting ring 6, thereby realizing the assembly of the quick-change system.

[0035] Specifically, thrust bearings may be provided between the pressure ring 7 and the fixed ring 5 and between the limit ring 6 and the retaining ring 4 to improve the smoothness of the rotation of the rotating column 2 outside the fixed column 1 .

[0036] Specifically, the pressure ring 7 is detachably connected to the end of the fixing column 1 by means of threaded connection or retaining spring.

[0037] Specifically, a receiving groove 21 is provided outside the rotating column 2 corresponding to each telescopic piece 3, and the side of the telescopic piece 3 close to the axis of the rotating column 2 is embedded in the receiving groove 21, and the limiting groove penetrates the rotating column 2 along the axial direction of the rotating column 2 and is connected with the retaining ring 4 and the card groove 9 on the fixing ring 5.

[0038] Specifically, each expansion piece 3 corresponds to a plurality of elastic members 8, and the plurality of elastic members 8 corresponding to the same expansion piece 3 are arranged along the axis of the rotating column 2. A plurality of mounting grooves 22 are provided on one side of the receiving groove 21 close to the axis of the rotating column 2. The plurality of mounting grooves 22 correspond to the plurality of elastic members 8, respectively, and the elastic members 8 are arranged in the corresponding mounting grooves 22; the mounting grooves 22 penetrate the rotating column 2 in a direction away from the axis of the rotating column 2, so as to facilitate the installation of the elastic member 8 into the mounting grooves 22.
