Description

Technical Field

[0001] The utility model belongs to the field of air-dropped water bags, and in particular relates to welding and forming equipment for air-dropped water bags. Background Art

[0002] Airdropped water bladders are extremely important for quickly resupplying water during wartime or in response to sudden disasters. Compared to traditional water bladders, airdropped water bladders must withstand strong impact forces, otherwise they will break and fail to achieve their purpose of water supply. Furthermore, airdropped water bladders in cold regions must ensure that they do not freeze during transportation and storage, which could affect normal drinking water. Furthermore, prolonged storage of drinking water in the bladders can easily breed bacteria and other harmful microorganisms, directly threatening the health of the drinker. Currently, the base material of airdropped water bladders is TPU composite, which has excellent thermal insulation, impact resistance, water retention, and lightweight properties.

[0003] When producing and molding the airdrop water bag, the water bag base material needs to be cut to form two upper and lower covering bodies and a side surrounding body. When welding the circumferential welding line between the covering body and the side surrounding body, the circumferential welding line of the covering body and the side surrounding body is manually positioned, and the pressing block in the high-frequency welding machine directly presses down the circumferential welding line of the covering body and the side surrounding body. Under the action of the high-frequency electromagnetic field of the high-frequency welding machine, the molecules inside the material collide violently with each other to produce high-temperature welding. However, directly pressing and welding with a high-frequency welding machine has the following technical problems: Technical defects: The operator needs to manually position the side enclosure and the cover body on the high-frequency welding machine, and needs to accurately adjust the position of the side enclosure and the cover body on the high-frequency welding machine. Once a position deviation occurs with the pressure block inside the high-frequency welding machine, it needs to be readjusted, otherwise it will affect the welding quality of the circumferential seam welding line and cause welding position deviation; and this direct high-frequency welding machine internal pressure block pressing welding method can only meet the welding forming of small-sized airdrop water bags, and is extremely inconvenient for the welding forming of large-sized airdrop water bags. Utility Model Content

[0004] The purpose of this utility model is to overcome the above shortcomings and provide a welding and forming equipment for airdrop water bags, which does not require the operator to repeatedly adjust the welding position of the cover body and the side surrounding body, ensures the welding quality of the circumferential seam welding line, and meets the welding and forming requirements of large-sized airdrop water bags.

[0005] The purpose of the utility model is achieved through the following technical solutions: a welding and forming device for an airdrop water bag, used for welding the annular connecting line between the cover body and the side surrounding body of the airdrop water bag, comprising a high-frequency welding machine and a sliding platform placed on one side of the high-frequency welding machine, the sliding platform having a clamping auxiliary forming mold, the clamping auxiliary forming mold entering or leaving the high-frequency welding machine along with the sliding platform;

[0006] The clamping auxiliary forming mold includes a base and a lower positioning plate placed on the base, and the base and the lower positioning plate are connected by multiple fixed struts, and the lower positioning plate is provided with an upper pressure plate, and the upper pressure plate is connected to the base with vertically arranged telescopic connecting column assemblies on all sides, the upper end of the telescopic connecting column assembly is fixedly connected to the lower end surface of the upper pressure plate, and the lower end of the telescopic connecting column assembly is fixedly connected to the base, and the telescopic connecting column assembly drives the upper pressure plate to rise and fall, thereby adjusting the distance between the upper pressure plate and the lower positioning plate, and the upper pressure plate is provided with a visible through hole, and the inner wall of the visible through hole is placed on the inner side of the outer wall of the lower positioning plate.

[0007] A further improvement of the present invention is that the outer edge of the upper end surface of the lower positioning plate has an inclined surface 1, and the lower end surface of the upper pressure plate is located at the outer edge of the visible through hole and has an inclined surface 2 that matches the inclined surface 1.

[0008] A further improvement of the present invention is that the telescopic connecting column assembly includes an insertion rod fixedly connected to the lower end surface of the upper pressure plate and a hollow support column fixed on the base, the end of the insertion rod vertically extends into the hollow support column, and the insertion rod and the hollow support column are clearance-matched.

[0009] A further improvement of the present invention is that the hollow support column has a through hole for accommodating the vertical insertion of the insertion rod, the through hole has an electric push rod for driving the insertion rod to move up and down, and the lower end of the insertion rod is non-contact connected to the driving end of the electric push rod.

[0010] A further improvement of the present invention is that a trumpet-shaped guide opening is provided at the upper end of the through hole.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. The utility model sets a sliding platform beside the high-frequency welding machine, and sets a clamping auxiliary forming mold on the sliding platform. The cover body and the side surrounding body are clamped and positioned on the clamping auxiliary forming mold, and slide into the high-frequency welding machine to weld the circumferential seam welding line.

[0013] 2. In the present invention, the inclined surface 1 on the lower positioning plate and the inclined surface 2 on the upper pressure plate cooperate with each other, and the outer circumference position of the cover body and the upper edge position of the side enclosure are pressed and overlapped here, which expands the contact area between the cover body and the side enclosure, improves the contact friction, and ensures the pressing force between the cover body and the side enclosure; secondly, when the side enclosure passes through the inclined surface 1 on the lower positioning plate from bottom to top, the bending angle is obtuse, which can better protect the inner wall structure of the side enclosure and avoid wear of the inner wall of the side enclosure compared to vertical bending.

DETAILED DESCRIPTION

[0022] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0023] In the description of the present invention, it should be understood that terms indicating orientation or positional relationships, such as the orientation or positional relationships based on the accompanying drawings, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the structure or unit referred to must have a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0024] In the present utility model, unless otherwise clearly stipulated and limited, terms such as "connected", "provided with", "having" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. It can be said to be a mechanical connection, or it can be directly connected, or it can be connected through an intermediate medium. For those skilled in the art, the basic meaning of the above terms in the present utility model can be understood according to the specific circumstances.

[0025] A welding and forming device for air-dropped water bags, such as Figures 1 to 3 As shown, the annular connection line between the cover body 1 and the side surrounding body 2 for welding the airdrop water bag includes a high-frequency welding machine 5 and a sliding platform 3 placed on one side of the high-frequency welding machine 5. The sliding platform 3 has a clamping auxiliary forming mold 4. The clamping auxiliary forming mold 4 enters or leaves the high-frequency welding machine 5 along with the sliding platform 3;

[0026] The clamping auxiliary forming mold 4 includes a base 41 and a lower positioning plate 42 placed on the base 41. There are multiple fixed struts 43 between the base 41 and the lower positioning plate 42. The lower positioning plate 42 has an upper pressure plate 44. The upper pressure plate 44 is connected to the base 41 on all sides with a vertically arranged telescopic connecting column assembly 45. The upper end of the telescopic connecting column assembly 45 is fixedly connected to the lower end surface of the upper pressure plate 44, and the lower end of the telescopic connecting column assembly 45 is fixedly connected to the base 41. The telescopic connecting column assembly 45 drives the upper pressure plate 44 to rise and fall, thereby adjusting the distance between the upper pressure plate 44 and the lower positioning plate 42. The upper pressure plate 44 has a visible through hole 46, and the inner wall of the visible through hole 46 is placed on the inner side of the outer wall of the lower positioning plate 42.

[0027] Working principle: The telescopic connecting column assembly 45 is lifted to separate the upper pressure plate 44 from the lower positioning plate 42, and the cover body 1 is positioned on the lower positioning plate 42, and the side surrounding body 2 is surrounded and positioned outside the clamping auxiliary forming mold 4. Figure 4The enclosing direction makes the upper end surface of the side enclosure 2 pass through the inclined surface 47 of the lower positioning plate 42, and the outer edge of the side enclosure 2 surrounded by the lower positioning plate 42 overlaps with the outer edge of the cover body 1 (the outer edge of the side enclosure 2 is placed on the upper side of the outer edge of the cover body 1), and the telescopic connecting column assembly 45 contracts, so that the upper pressure plate 44 presses the lower positioning plate 42 downward, thereby pressing the side enclosure 2 and the cover body 1 tightly. As the sliding platform 3 enters the high-frequency welding machine 5, the high-frequency electromagnetic field of the high-frequency welding machine 5 causes the internal molecules of the mutually clamped side enclosure 2 and the cover body 1 to collide violently with each other at the connection point to produce high-temperature welding. After the circumferential seam welding line is completed, the telescopic connecting column assembly 45 is lifted, and the upper pressure plate 44 is separated from the lower positioning plate 42, and the welded cover body 1 and the side enclosure 2 are turned over for the next welding process (the other end of the side enclosure 2 is welded to the other cover body 1 again).

[0028] The utility model is provided with a sliding platform 3 beside the high-frequency welding machine 2, and a clamping auxiliary forming mold 4 is provided on the sliding platform 3. The cover body 1 and the side surrounding body 2 are clamped and positioned on the clamping auxiliary forming mold 4, and slide into the high-frequency welding machine 5 to weld the circumferential seam welding line. There is no need for the operator to repeatedly adjust the welding position of the cover body 1 and the side surrounding body 2, and the pressing of the pressure block of the high-frequency welding machine 5 is cancelled, thereby ensuring the welding quality and welding position accuracy of the circumferential seam welding line, and meeting the welding forming requirements of large-sized airdrop water bags.

[0029] Based on this embodiment, the outer edge of the upper end surface of the lower positioning plate 42 has an inclined surface 1 47 , and the lower end surface of the upper pressure plate 44 located at the outer edge of the visible through hole 46 has an inclined surface 2 48 that matches the inclined surface 1 47 .

[0030] In the present invention, the inclined surface 1 47 on the lower positioning plate 42 cooperates with the inclined surface 2 48 on the upper pressure plate 44, and the outer circumferential position of the cover body 1 and the upper edge position of the side surrounding body 2 are pressed and overlapped here, thereby expanding the contact area between the cover body 1 and the side surrounding body 2, improving the contact friction, and ensuring the pressing force between the cover body 1 and the side surrounding body 2.

[0031] Secondly, when the side enclosure 2 passes through the inclined surface 47 on the lower positioning plate 42 from bottom to top, the bending angle is an obtuse angle, which can better protect the inner wall structure of the side enclosure 2 and avoid wear of the inner wall of the side enclosure 2 compared to vertical bending.

[0032] Based on this embodiment, the telescopic connecting column assembly 45 includes an insertion rod 451 fixedly connected to the lower end surface of the upper pressure plate 44 and a hollow support column 452 fixed on the base 41. The end of the insertion rod 451 extends vertically into the hollow support column 452, and the insertion rod 451 and the hollow support column 452 are clearance-matched.

[0033] Based on this embodiment, the hollow support column 452 has a through hole 453 for the insertion rod 451 to be vertically inserted, and the through hole 453 has an electric push rod 454 for driving the insertion rod 451 to move up and down, and the lower end of the insertion rod 451 is not contact-connected to the driving end of the electric push rod 454.

[0034] In the present application, if there is no electric push rod 454, the technical solution of the present application can also be implemented, and manual removal or installation of the upper pressure plate 44 is required. However, when positioning the cover body 1 and the side surrounding body 2, one operator is required to position the cover body 1 on the lower positioning plate 42 and surround the side surrounding body 2 outside the lower positioning plate 42 (the operator is required to continuously position the side surrounding body 2). At the same time, two operators are required to move the upper pressure plate 44 until the upper pressure plate 44 is pressed tightly against the lower positioning plate 42. Therefore, three operators are required to operate at the same time.

[0035] After the electric push rod 454 is set, two operators move the upper pressure plate 44, the electric push rod 454 is lifted, and the insertion rod 451 on the lower side of the upper pressure plate 44 cooperates with the hollow support column 452. At this time, the upper pressure plate 44 is initially positioned on the upper side of the lower positioning plate 42, but there is a certain distance between the upper pressure plate 44 and the lower positioning plate 42. The two operators evacuate the upper pressure plate 44 and then position the covering body 1 and the side surrounding body 2. Therefore, only two operators are needed to operate at the same time. When the positioning is completed, the electric push rod 454 retracts, and the upper pressure plate 44 moves downward by itself under the action of its own gravity and then clamps the annular welding line between the covering body 1 and the side surrounding body 2.

[0036] It should be noted that the lower end of the insertion rod 451 is not in contact with the driving end of the electric push rod 454, which facilitates the subsequent removal of the upper pressure plate 44 after welding is completed, and further facilitates the removal of the cover body 1 and the side surrounding body 2.

[0037] Based on this embodiment, the upper end of the through hole 453 has a trumpet-shaped guide opening 455. The setting of the guide opening 455 plays a good guiding and positioning role in positioning the insertion rod 451 at the lower end of the upper pressure plate 44 and the hollow support column 452.

[0038] Those skilled in the art should understand that the present invention is not limited to the above-described embodiments. The above-described embodiments and the specification are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
