Description

Technical Field

[0001] This utility model mainly relates to the field of automatic bending machines, specifically to a strip feeding device for an automatic bending machine. Background Technology

[0002] In modern large storage tanks (such as crude oil and chemical product storage tanks), internal floating roofs are commonly used as energy-saving and environmentally friendly devices to cover the liquid surface in order to reduce the evaporation loss of the medium. Internal floating roofs are typically assembled from multiple float units using specific connecting components. Among these, L-shaped bending strips, as a key connecting and sealing component, are widely used for splicing and fixing between the edge units of the floating roof. These L-shaped strips must have precise bending angles and consistent dimensions to ensure that the assembled internal floating roof has sufficient structural strength, sealing performance, and flatness. When bending strips, the automatic bending machine requires the strips to be placed inside the machine.

[0003] During the operation of specific embodiments, the inventors discovered the following defects: Traditional production methods mostly involve manually pushing long strips of metal or composite materials into bending dies. This method is not only labor-intensive and inefficient, but also makes it difficult to guarantee the accuracy of the feeding length, resulting in large dimensional deviations in the bent L-shaped parts, which directly affects the splicing quality of the inner floating plate.

[0004] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0019] See attached document Figure 1-3 A strip feeding device for an automatic bending machine includes a feeding structure 1, wherein a feeding structure 2 is slidably connected to the top of the feeding structure 1. The feeding structure 2 includes a movable frame 201. A flexible strip 202 is provided on the outer wall of the movable frame 201, and the flexible strip 202 is connected to the feeding structure 1. Slide strips 203 are provided on both sides of the bottom of the movable frame 201. A drive wheel is provided at the bottom of each slide strip 203. An auxiliary plate 209 is provided in the middle of the bottom of the movable frame 201. A clamping structure is provided at the top of the movable frame 201. The clamping structure includes an electric push rod 204, which is rotatably connected to the top of the movable frame 201. A rotating bar 205 is rotatably connected to the top of the movable frame 201. 05 is rotatably connected to the electric push rod 204. One end of the rotating bar 205 is provided with a vertical rod 206. A pressure plate 208 is provided directly below the vertical rod 206. The pressure plate 208 and the vertical rod 206 are rotatably connected through a spherical rotating device 207. When the strip enters the front of the feeding structure 2, one end of the strip is aligned with the auxiliary plate 209. Then, the electric push rod 204 is started to feed the strip. The electric push rod 204 pushes the rotating bar 205 to rotate. The rotating bar 205 drives the vertical rod 206 to move downward. The vertical rod 206 drives the pressure plate 208 to move downward. The pressure plate 208 and the auxiliary plate 209 cooperate to clamp the strip. Then the drive wheel is started, and the drive wheel slides on the inner wall of the second guide groove 104. Then the drive wheel drives the moving frame 201 to move to one side of the feeding frame 101. The moving frame 201 drives the strip into the interior of the automatic bending machine through the clamping structure.

[0020] Furthermore, the feeding structure 1 includes a feeding rack 101. A mounting groove 102 is formed on one side of the top of the feeding rack 101, and a first guide groove 103 is formed on the other side of the top of the feeding rack 101. Second guide grooves 104 are formed on both sides of the first guide groove 103. Support bars 105 are provided on the inner wall of the mounting groove 102. Two support bars 105 are provided. A first blocking bar 106 is provided on one side of each support bar 105, and a second blocking bar 108 is provided on the other side of each support bar 105. A connecting bar 107 is provided between the second blocking bar 108 and the support bar 105. A cylinder 1 is provided on the top of the feeding rack 101. 09. The output end of the cylinder 109 is provided with a positioning plate 110, and the top of the positioning plate 110 is provided with a top plate 111. When the strip needs to be fed into the interior of the automatic bending machine to process the L-shaped strip of the inner floating plate by the feeding device, the strip is placed between the first blocking bar 106 and the second blocking bar 108, and there is a gap between the second blocking bar 108 and the positioning plate 110. Then the cylinder 109 is started, and the cylinder 109 pushes the positioning plate 110 forward. The top plate 111 at the top of the positioning plate 110 is used to block the top strip from moving downward, so that the bottom strip is pushed to the front of the feeding structure 2 through the gap between the feeding rack 101 and the second blocking bar 108.

[0021] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
