Description

Technical Field

[0001] The present invention relates to the field of welding technology, in particular to a welding device for producing a folding cigarette display rack. Background Art

[0002] The folding cigarette display rack breaks through the limitations of traditional shops selling cigarettes at fixed counters, and provides a flexible and efficient sales solution for mobile vendors, night market stalls and temporary promotional activities. Compared with the shortcomings of traditional cigarette cabinets that are bulky and immovable, this display rack adopts a hinge structure or a multi-section folding design, which can be quickly unfolded into a stable display platform. When stored, it can be folded into a compact form, which is easy to carry and transport. It is not only convenient for vendors to operate on the streets, markets or event venues with heavy traffic, but also can adjust the display angle according to different sales scenarios to maximize the display effect. Through lightweight materials (such as aluminum alloy or thin-walled stainless steel) and stable welding technology, the folding cigarette display rack strikes a balance between portability and durability, significantly broadening the coverage scenarios of tobacco retail and creating more profit opportunities for small and micro businesses.

[0003] The existing welding devices for foldable cigarette display racks still have several practical deficiencies. Since the inner wall of the cover serves as the core display area, multiple brands and sizes of cigarettes need to be arranged in a reasonable manner, placing high demands on the precision and efficiency of the partition welding. However, in traditional manufacturing processes, the welding and positioning of the partitions relies entirely on manual labor. Workers must manually measure and determine the spacing between the partitions, and constantly adjust them during the welding process to ensure the perpendicularity between the partitions and the cover. This makes it difficult to ensure accuracy, and manual measurement and positioning can easily lead to cumulative errors, resulting in uneven partition spacing, affecting the overall aesthetics and practicality. Welding efficiency is low, as each partition requires multiple welds on both sides and longitudinally, which is cumbersome and time-consuming to weld a single partition. Quality is also inconsistent, as manual deviations in maintaining the perpendicularity can lead to insufficient structural strength after welding or difficulty in assembly. Production costs are high, and the excessive reliance on skilled labor not only increases labor costs but also hinders standardized mass production. Therefore, a welding device for foldable cigarette display racks is proposed to address these issues. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the background technology and to propose a welding device for producing a folding cigarette display rack.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0034] The horizontal and vertical synchronous welding mechanism 202 includes a fixed rod 29 and a fixed rod 37.

[0039] In this embodiment, when in use, the cover plate 10 is placed on the supporting frame 7, and several partitions 11 are placed between the horizontal push plate 6 and the storage frame 8. The longitudinal telescopic rod 42 is extended to drive the displacement connecting plate 16 and the storage frame 8 to move upward, so that the partition 11 on the innermost side of the storage frame 8 conflicts with the longitudinal push plate 3, so that the partition 11 falls between the two longitudinal limit plates 32 and is clamped by the clamping plate 39.

[0040] Then the longitudinal telescopic rod 42 retracts, so that the longitudinal limit plate 32 and the limit frame 13 extend into the cover plate 10, and the partition 11 is tightly attached to the inner wall of the cover plate 10. The partition 11 is limited by the clamping plate 39 and always remains vertical to the cover plate 10 without manual support. When the electric telescopic rod 12 is fully extended, the fixed rod 2 37 and the fixed rod 1 29 are located above the frame of the cover plate 10, which will not affect the normal falling of the partition 11.

[0041] Among them, the outer wall of the fixed side plate 4 is provided with an automatic spacing adjustment structure 101, and the automatic spacing adjustment structure 101 includes a connecting frame 21, the connecting frame 21 is fixedly connected to the fixed side plate 4, and the outer wall of the positioning hole 24 is rotatably connected to the ratchet 20 and the first gear 23.

[0043] Among them, a plurality of positioning holes 24 are opened on the outer wall of the bottom of the supporting frame 7, and the number of the positioning holes 24 is consistent with that of the partition 11. The inner wall of the base 1 is slidably connected with an insertion rod 25, and the end of the insertion rod 25 is arc-shaped. A second spring 26 is fixedly connected between the base 1 and the insertion rod 25.

[0044] In this embodiment, the connecting rod 17 drives the second rack 19 to move upward at the same time, so that the first gear 23 drives the ratchet 20 to rotate through the pawl assembly 22, and the ratchet 20 drives the first rack 18 to move, so that the supporting frame 7 moves with the cover plate 10 to the bottom of the storage frame 8. At this time, the insertion rod 25 is inserted into the first positioning hole 24 on the outer wall of the supporting frame 7 to complete the spacing adjustment.

[0045] Finally, the two electric telescopic rods 12 are retracted, so that the second fixing rod 37 and the driving rod 28 push the limit seats 31, the mounting seats 15 and the welding gun 14 on both sides to slide to the middle position along the slide rail 1 38. After the mounting seats 15 at both ends of the slide rail 1 38 are tightly attached, the second fixing rod 37 and the driving rod 28 squeeze into the inclined clamping plate 30 and the limit seat 31, completing the docking of the welding process.

[0046] Then the welding gun 14 is started, so that the welding gun 14 welds the bottom surfaces of the partition 11 and the cover plate 10 on both sides. When the mounting seat 15 moves to the two ends of the slide rail 1 38, the longitudinal telescopic rod 42 moves up to the same length as the cover plate 10, so that the welding gun 14 welds the partition 11 and the longitudinal inner wall of the cover plate 10. Finally, the electric telescopic rod 12 is fully extended, so that the limit seat 31 is disengaged from the fixed rod 2 37 and the driving rod 28, and the longitudinal telescopic rod 42 is also fully extended, continuing to drive the partition 11 under the longitudinal push plate 3 to squeeze into the longitudinal limit plate 32, and at the same time drive the supporting frame 7 to move a distance so that the insertion rod 25 is inserted into the next positioning hole 24.

[0047] The specific working principle and usage method of the present invention are explained in detail below: when in use, the cover plate 10 is placed on the supporting frame 7, and several partitions 11 are placed between the horizontal pushing plate 6 and the storage frame 8. The longitudinal telescopic rod 42 is extended to drive the displacement connecting plate 16 and the storage frame 8 to move upward, so that the partition 11 on the innermost side of the storage frame 8 conflicts with the longitudinal pushing plate 3, so that the partition 11 falls between the two longitudinal limit plates 32 and is clamped by the clamping plate 39. At the same time, the connecting rod 17 drives the second rack 19 to move upward, so that the first gear 23 drives the ratchet 20 to rotate through the pawl assembly 22, and the ratchet 20 drives the first rack 18 to move, so that the supporting frame 7 moves with the cover plate 10 to the bottom of the storage frame 8. At this time, the insertion rod 25 is inserted into the first positioning hole 24 on the outer wall of the supporting frame 7 to complete the spacing adjustment.

[0048] Then the longitudinal telescopic rod 42 retracts, so that the longitudinal limit plate 32 and the limit frame 13 extend into the cover plate 10, and the partition 11 is tightly attached to the inner wall of the cover plate 10. The partition 11 is limited by the clamping plate 39 and always remains vertical to the cover plate 10 without manual support. When the electric telescopic rod 12 is fully extended, the fixed rod 2 37 and the fixed rod 1 29 are located above the frame of the cover plate 10, which will not affect the normal falling of the partition 11.

[0049] Finally, the two electric telescopic rods 12 are retracted, so that the second fixing rod 37 and the driving rod 28 push the limit seats 31, the mounting seats 15 and the welding gun 14 on both sides to slide to the middle position along the slide rail 1 38. After the mounting seats 15 at both ends of the slide rail 1 38 are tightly attached, the second fixing rod 37 and the driving rod 28 squeeze into the inclined clamping plate 30 and the limit seat 31, completing the docking of the welding process.

[0050] Then the welding gun 14 is started, so that the welding gun 14 welds the bottom surfaces of the partition 11 and the cover plate 10 on both sides. When the mounting seat 15 moves to the two ends of the slide rail 1 38, the longitudinal telescopic rod 42 moves up to the same length as the cover plate 10, so that the welding gun 14 welds the partition 11 and the longitudinal inner wall of the cover plate 10. Finally, the electric telescopic rod 12 is fully extended, so that the limit seat 31 is disengaged from the fixed rod 2 37 and the driving rod 28, and the longitudinal telescopic rod 42 is also fully extended, continuing to drive the partition 11 under the longitudinal push plate 3 to squeeze into the longitudinal limit plate 32, and at the same time drive the supporting frame 7 to move a distance so that the insertion rod 25 is inserted into the next positioning hole 24.

[0051] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are common means well known to those skilled in the art.
