Abstract
Description
Technical Field
[0001] This utility model relates to the field of hole-pull belt processing technology, and in particular to an auxiliary forming tool for hole-pull belts. Background Technology
[0002] Inflatable mattresses are becoming increasingly popular due to their portability and minimal storage space requirements, such as for outdoor camping and picnics. A typical inflatable mattress structure includes an upper panel, a lower panel, a pull strap, and surrounding straps. The pull strap is usually a ring-shaped structure, with its top and bottom welded to the lower surface of the upper panel and the upper surface of the lower panel, respectively. When the inflatable mattress is inflated, the pull strap tightens the upper and lower panels, keeping the mattress surface flat.
[0003] Traditional perforated stretch tape processing typically uses fixed molds. Long strips of film are manually cut, then wrapped around the mold and the ends are welded together to form the perforated stretch tape. However, this processing method is not only inefficient, but the fixed molds also make demolding very inconvenient. Utility Model Content
[0004] Therefore, it is necessary to provide a hole-pulling tape auxiliary forming tool to address the shortcomings of existing technologies.
[0005] A tooling for assisting in the forming of a perforated strap includes a main support rod, two sets of auxiliary support rods, several movable rotating rods, and several forming modules. The main support rod and the two sets of auxiliary support rods are all elongated structures, with the two sets of auxiliary support rods respectively located on both sides of the main support rod. The main support rod also has several pivot holes penetrating both sides, and the two sets of auxiliary support rods have corresponding connecting holes penetrating both sides. Several movable rotating rods are respectively pivotally connected to the pivot holes of the main support rod and can rotate. The two ends of these movable rotating rods are respectively pivotally connected to the connecting holes on the two sets of auxiliary support rods.
[0006] Furthermore, the molding module includes a through block and a molding ring. The through block has a first through hole extending through both sides. The molding ring has a ring-shaped structure and is sleeved on the outside of the through block. The side of the molding ring also has a second through hole and a perforated hole. The main support rod passes through the second through hole and the first through hole in sequence to fix the through block and the molding ring on it.
[0007] Furthermore, each end of the main support rod is provided with a protective sleeve. The protective sleeve is designed in the shape of a square column and is fixedly fitted onto the end of the main support rod.
[0008] Furthermore, the hole-pulling belt auxiliary forming tooling also includes a limiting piece, which is installed on one side of the main support rod and one end of it abuts against and limits the movable rotating rod.
[0009] Furthermore, both the main support rod and the auxiliary support rod are designed as hollow structures with openings at both ends.
[0010] In summary, the beneficial effects of this utility model's auxiliary forming fixture for perforated pull strips are as follows: by designing an adjustable auxiliary forming fixture, the perforated pull strips can be demolded more easily and conveniently after processing, greatly improving the efficiency and reliability of perforated pull strip processing; the forming module and the main support rod are designed as an assembly forming structure, allowing the auxiliary forming fixture to flexibly adjust the number and specifications of forming modules according to the production needs of perforated pull strips of different specifications and quantities, greatly expanding its applicability; this utility model is highly practical and has significant promotional value.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.
[0019] like Figures 1 to 7 As shown, this utility model provides a hole-pulling belt auxiliary forming tool 100, which includes a main support rod 10, two sets of auxiliary support rods 20, several movable rotating rods 30 and several forming modules 40.
[0020] The main support rod 10 and the two sets of auxiliary support rods 20 are both designed as elongated structures, with the two sets of auxiliary support rods 20 respectively located on both sides of the main support rod 10. The main support rod 10 is also provided with several pivot holes 11 penetrating both sides, and the two sets of auxiliary support rods 20 are respectively provided with several connecting holes 21 penetrating both sides. Several movable rotating rods 30 are respectively axially connected to the pivot holes 11 of the main support rod 10 and can rotate movably. The two ends of these movable rotating rods 30 are respectively axially connected to the several connecting holes 21 on the two sets of auxiliary support rods 20.
[0021] When processing the perforated pull strip, first adjust the rotating rod 30 to adjust the fixture so that the main support rod 10 and the auxiliary support rods 20 on both sides maintain a large distance. Then, wrap the cut strip around the fixture and weld the ends to form a loop-shaped perforated pull strip. Next, adjust the rotating rod 30 again to reduce the distance between the main support rod 10 and the auxiliary support rods 20 on both sides. At this time, a clear gap will appear between the formed perforated pull strip and the fixture, allowing the fixture to be easily pulled out of the loop-shaped perforated pull strip.
[0022] The molding module 40 includes a through block 41 and a molding ring 42. The through block 41 has a first through hole 411 extending through both sides. The molding ring 42 has a ring-shaped structure and is sleeved on the outside of the through block 41. The side of the molding ring 42 also has a second through hole 421 and a hollow hole 422. The main support rod 10 passes through the second through hole 421 and the first through hole 411 in sequence to fix the through block 41 and the molding ring 42 on it. The molding module 40, which is flexibly assembled on the support rod, is easier to assemble and disassemble, thus enabling it to be matched with different numbers of perforated strips for processing and molding. The hollow hole 422 design of the molding ring 42 can further reduce the contact area between the perforated strip and the molding module 40, making the perforated strip easier to demold.
[0023] The main support rod 10 is also provided with protective sleeves 12 at both ends. The protective sleeves 12 are square column-shaped and fixedly fitted onto the ends of the main support rod 10. The square column-shaped protective sleeves 12 can not only effectively prevent the tooling from accidentally rolling over during use and affecting the forming of the hole-pulling belt, but also make it easier for manual or automatic equipment to pick up, put down and transfer the tooling.
[0024] The hole-pulling tape auxiliary forming fixture 100 also includes a limiting piece 50, which is installed on one side of the main support rod 10 and has one end abutting against and limiting the movable rotating rod 30. The limiting piece 50 can limit the movable rotating rod 30, preventing the movable rotating rod 30 from rotating accidentally during the hole-pulling tape forming process, thus avoiding the problem of affecting the hole-pulling tape forming effect.
[0025] Both the main support rod 10 and the auxiliary support rod 20 are hollow structures with openings at both ends. The hollow structure of the main support rod 10 and the auxiliary support rod 20 not only saves on the cost of manufacturing tooling, but also reduces the weight of the tooling, making it easier for manual or mechanical equipment to pick up, place, or transfer the tooling.
[0026] In summary, the beneficial effects of this utility model's auxiliary forming fixture 100 for perforated pull strips are as follows: by designing an adjustable auxiliary forming fixture, the perforated pull strips can be demolded more easily and conveniently after processing, greatly improving the efficiency and reliability of perforated pull strip processing; the forming module 40 and the main support rod 10 are designed as an assembly forming structure, allowing the auxiliary forming fixture to flexibly adjust the number and specifications of the forming module 40 according to the production needs of perforated pull strips of different specifications and quantities, greatly expanding its applicability; this utility model is highly practical and has strong promotional significance.
[0027] The embodiments described above illustrate only one implementation of the utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept, and these all fall within the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be determined by the appended claims.
