Description

Technical Field

[0001] This utility model belongs to the technical field of flattening equipment, and specifically relates to a flattening device with an edge-guided positioning structure. Background Technology

[0002] Many existing flattening devices lack precise edge-guiding and positioning structures, making it easy for the edges of the material to shift or misalign during the flattening process. This results in inconsistent dimensional accuracy of the flattened workpiece, deviating from the design dimensions and affecting the accuracy and efficiency of subsequent processes. Uneven pressure distribution between the material edges and the flattening rollers during flattening can also lead to excessive deformation or even damage, such as curling, indentations, and scratches, reducing the surface quality and appearance of the workpiece.

[0003] Conventional solutions include: employing more precise positioning mechanisms, such as photoelectric sensors and laser sensors, to detect and position material edges in real time, and using precision control devices such as servo motors to adjust the position and pressure of the flattening rollers; and improving the design of the flattening rollers. However, these methods also have some drawbacks: high-precision sensors and control systems are expensive, increasing equipment investment costs; improving the design of the flattening rollers and using auxiliary guiding devices increases equipment complexity and maintenance difficulty; the pre-flattening process requires additional equipment and procedures, increasing production time and costs; and some methods may still not completely solve the problem of edge deformation and scratches, especially when processing workpieces with uneven material thickness or hard materials. Therefore, we hope to design a flattening device with a novel structure to solve this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a flattening device with an edge-guided positioning structure to solve the problems mentioned in the background technology.

[0005] This utility model is achieved through the following technical solution: a flattening device with an edge guiding and positioning structure, comprising: a flattening component and a positioning and guiding component, wherein the flattening component is provided with a positioning and guiding component for positioning and guiding the edge of the product to be flattened on the front side;

[0006] The positioning and guiding assembly includes a fixed rod, a mounting frame, an upper guide roller, and a lower guide roller. The left and right ends of the fixed rod are respectively movably mounted with a mounting frame for supporting the upper guide roller and the lower guide roller. Each mounting frame has an upper guide roller and a lower guide roller rotatably mounted on the inner side of its upper end for guiding and positioning the product edge.

[0007] In a preferred embodiment, the flattening assembly includes a support and flattening rollers. The left and right ends of the two vertically aligned flattening rollers are rotatably connected to the inside of a support. In actual use, two flattening rollers are provided, and a gap is provided between the two flattening rollers. The upper flattening roller is movable and can be adjusted within a small range to accommodate products of different thicknesses.

[0008] In a preferred embodiment, a limiting protrusion is provided radially outward on the outer wall of the outer end of the upper guide roller, and a guide groove limiting protrusion is provided radially inward on the outer wall of the outer end of the lower guide roller. This can limit the edge of the product and prevent it from shifting to the outer side between the upper guide roller and the lower guide roller when the edge of the product shifts, thus helping to improve the stability of the product when flattening.

[0009] In a preferred embodiment, the radial depth of the guide groove matches the radial length of the limiting protrusion, and the width of the guide groove matches the width of the limiting protrusion.

[0010] In a preferred embodiment, a gap is provided between the outer wall of the upper guide roller and the outer wall of the lower guide roller, and the limiting protrusion is in rolling connection with the inside of the guide groove.

[0011] In a preferred embodiment, the mounting bracket includes a mounting base, a mounting block, a fixing block, and a mounting rod. The lower end of the mounting base forms a through hole from left to right, and the lower end of the through hole forms a notch for engaging with a locking knob to lock the connecting rod.

[0012] In a preferred embodiment, a fixing block for supporting the mounting block is installed on the upper end of the mounting base, and a mounting rod is movably installed on the upper side of the fixing block by bolts, with the inner end of the mounting rod being fixedly connected to the outer end of the mounting block.

[0013] In a preferred embodiment, a connecting rod for mounting the lower guide roller is fixed to the lower inner end of the mounting block, and a groove for movably mounting the swing block is formed by a downward indentation at the upper end of the mounting block. A swing block for mounting the upper guide roller is movably mounted at the upper end of the mounting block via a pin.

[0014] In a preferred embodiment, the outer end of the swing block is threaded with a limiting bolt for limiting the position, and the lower end of the limiting bolt is in movable contact with the upper side of the mounting rod.

[0015] The inner end of the swing block is slidably connected to the lower side of the guide post, the lower end of the guide post is fixedly connected to the upper side of the connecting rod, and the upper end of the guide post is fitted with a compression spring for pressing the inner end of the swing block.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are as follows: by setting the positioning and guiding components, when the edge of the product contacts the upper guide roller and the lower guide roller, the limiting protrusion ring located on the outer wall of the upper guide roller can limit the edge of the product, while the upper guide roller and the lower guide roller guide the edge of the product. This can prevent the edge of the product from wrinkling or deflecting when entering the flattening component, which would cause excessive deformation or even damage to the edge, such as defects such as curling, indentation, and scratches. This helps to improve the surface quality and appearance of the workpiece.

[0017] The mounting rod and fixing block can adjust the upper and lower guide rollers on both sides to move in opposite directions, thereby changing the distance between the upper and lower guide rollers on both sides. This allows the equipment to adapt to products of different widths, helping to improve the equipment's adaptability. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 3 The present invention provides a technical solution: a flattening device with an edge guiding and positioning structure, comprising: a flattening component 100 and a positioning guide component 200, wherein the flattening component 100 is provided with a positioning guide component 200 for positioning and guiding the edge of the product to be flattened on the front side;

[0026] The positioning and guiding assembly 200 includes a fixed rod 210, a mounting frame 230, an upper guide roller 220, and a lower guide roller 240. The left and right ends of the fixed rod 210 are respectively movably mounted with a mounting frame 230 for supporting the upper guide roller 220 and the lower guide roller 240. Each mounting frame 230 has an upper guide roller 220 and a lower guide roller 240 rotatably mounted on the inner side of its upper end for guiding and positioning the product edge.

[0027] Please see Figures 1 to 3 The flattening assembly 100 includes a support 110 and flattening rollers 120. The left and right ends of two vertically aligned flattening rollers 120 are rotatably connected to the inside of a support 110. In actual use, two flattening rollers 120 are provided, and a gap is provided between the two flattening rollers 120. The upper flattening roller 120 is movable and can be adjusted within a small range to accommodate products of different thicknesses.

[0028] A limiting protrusion ring 221 is provided radially outward on the outer wall of the outer end of the upper guide roller 220, and a guide groove 241 is provided radially inward on the outer wall of the outer end of the lower guide roller 240. The limiting protrusion ring 221 can limit the edge of the product. When the edge of the product deviates, it can limit the edge and prevent it from deviating to the outside between the upper guide roller 220 and the lower guide, which helps to improve the stability of the product when flattening.

[0029] The radial depth of the guide groove 241 matches the radial length of the limiting protrusion 221, and the width of the guide groove 241 matches the width of the limiting protrusion 221.

[0030] A gap is provided between the outer wall of the upper guide roller 220 and the outer wall of the lower guide roller 240, and the limiting protrusion 221 is in rolling connection with the inside of the guide groove 241.

[0031] As the first embodiment of this utility model, by setting the positioning and guiding component 200, in actual use, the product to be flattened is first turned and transported to the flattening component 100 by guide rollers, etc. Before entering the flattening component 100, the two sides of the product are positioned and guided by the two sets of upper guide rollers 220 and lower guide rollers 240. When the edge of the product contacts the upper guide rollers 220 and lower guide rollers 240, the limiting protrusion ring 221 located on the outer wall of the upper guide roller 220 can limit the edge of the product, while the upper guide rollers 220 and lower guide rollers 240 guide the edge of the product. This can prevent the edge of the product from wrinkling or deflecting when entering the flattening component 100, which would cause excessive deformation or even damage to the edge, such as defects such as curling, indentation, and scratches. This helps to improve the surface quality and appearance of the workpiece.

[0032] Please see Figures 2 to 3 The mounting bracket 230 includes a mounting base 232, a mounting block 233, a fixing block 238, and a mounting rod 239. The lower end of the mounting base 232 forms a through hole from left to right, and the lower end of the through hole forms a notch for locking the connecting rod 234 with the locking knob 231.

[0033] The upper end of the mounting base 232 is equipped with a fixing block 238 for supporting the mounting block 233. The upper side of the fixing block 238 is movably mounted with a mounting rod 239 by bolts. The inner end of the mounting rod 239 is fixedly connected to the outer end of the mounting block 233.

[0034] The lower inner side of the mounting block 233 is fixed with a connecting rod 234 for mounting the lower guide roller 240. The upper end of the mounting block 233 is recessed downward to form a groove for movably mounting the swing block 235. The upper end of the mounting block 233 is movably mounted with a swing block 235 for mounting the upper guide roller 220 via a pin.

[0035] The outer end of the swing block 235 is threaded with a limiting bolt 237 for limiting, and the lower end of the limiting bolt 237 is in movable contact with the upper side of the mounting rod 239.

[0036] The inner end of the swing block 235 is slidably connected to the lower side of the guide post 236, the lower end of the guide post 236 is fixedly connected to the upper side of the connecting rod 234, and a compression spring for pressing the inner end of the swing block 235 is sleeved on the upper end of the guide post 236.

[0037] As a second embodiment of this utility model, based on the first embodiment described above, by setting up a swinging component, guide post 236, and limiting bolt 237, the upper guide roller 220 can be moved upward when necessary, thereby adapting to changes in product thickness within a certain range. This avoids the feeling of blockage caused by sudden thickness changes when the product passes through the upper guide roller 220 and lower guide roller 240, which could lead to wrinkles in the product. The mounting rod 239 and fixing block 238 can adjust the upper guide roller 220 and lower guide roller 240 on both sides to move in opposite directions when necessary, thereby changing the distance between the upper guide roller 220 and lower guide roller 240 on both sides. This allows the equipment to adapt to products of different widths, helping to improve the adaptability of the equipment.
