Description

Technical Field

[0001] This utility model relates to the field of material processing equipment technology, and in particular to a pressure plate mechanism with a positioning edge. Background Technology

[0002] A pressure plate mechanism with positioning edges is a device used to fix and smooth sheet metal during material processing. It is typically installed on a lifting platform or other processing equipment, applying pressure and rolling friction to the sheet metal through the pressure plate and smoothing device to ensure the flatness and stability of the sheet metal during processing. This mechanism is widely used in metal processing, plastic molding, composite material processing, and many other fields, and is an important tool for improving the quality and efficiency of material processing.

[0003] In existing technologies, a pressure plate mechanism typically includes a top plate fixed to the equipment, with a pressure plate located below the top plate for pressing the material. A smoothing roller is connected below the pressure plate via a fixing device for smoothing the material surface. During operation, the material is first placed on the worktable, and then the pressure plate is pressed down manually or mechanically to fix the material on the worktable. Subsequently, external equipment (such as a lift) moves the pressure plate mechanism up and down to complete the material processing.

[0004] While existing pressure plate mechanisms can meet basic material fixing and smoothing requirements, the smoothing rollers struggle to consistently press firmly against both sides of materials of varying lengths. This limits the applicability of the smoothing rollers in processing materials of different lengths, leading to material loosening during processing and consequently affecting processing quality and efficiency. Therefore, a pressure plate mechanism with positioning edges is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a pressure plate mechanism with positioning edges, which aims to improve the problem in the prior art that the smoothing roller cannot always press the two sides of the material according to the length of the material plate, thereby improving processing stability and efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pressure plate mechanism with a positioning edge, comprising a top plate, two extension rods fixedly connected to the front and back sides of the top plate respectively, a connecting rod rotatably connected to the surface of each extension rod, a smoothing roller rotatably connected to the bottom end of each of the two connecting rods, two smoothing rollers, and a pressure plate provided below the top plate;

[0007] The pressure plate is provided with an adjustment structure, which includes a threaded rod that is threaded through the top of the top plate. The bottom end of the threaded rod is rotatably connected to a connecting plate via a bearing. The bottom of the connecting plate is detachably connected to the top of the pressure plate. A guide rod is fixedly connected to the top of the connecting plate. The top end of the guide rod movably passes through the bottom of the top plate. A collection structure is provided on the connecting rod.

[0008] As a further description of the above technical solution: the collecting structure includes an extension plate, which is fixedly connected to the outside of the connecting rod. The inner side of the extension plate contacts the outer shell. The front and back sides of the outer shell are respectively provided with threaded grooves. The outer wall of the extension plate is threadedly connected to the inner wall of the threaded groove by bolt B. The top of the outer shell is provided with an opening. The side of the outer shell near the smoothing roller is provided with an arc surface and contacts the outer surface of the smoothing roller.

[0009] As a further description of the above technical solution: the bottom of the connecting plate contacts the top of the pressure plate, and the top four corners of the connecting plate are respectively threaded to the top of the pressure plate by bolts A.

[0010] As a further description of the above technical solution: the top end of the guide rod is fixedly connected to a limiting plate, and there are two guide rods and two limiting plates, which are symmetrically arranged on the top of the pressure plate.

[0011] As a further description of the above technical solution: there are two sets of connecting rods, and each set has two connecting rods. The outer surfaces of the two connecting rods are respectively fixedly connected to a fixing plate, and the two ends of the spring are respectively fixedly connected to the adjacent side of the two fixing plates.

[0012] As a further description of the above technical solution: a knob is fixedly connected to the top end of the threaded rod.

[0013] As a further description of the above technical solution: mounting plates are fixedly connected to the four sides of the top plate, and threaded holes are respectively opened on the surface of the mounting plates.

[0014] As a further description of the above technical solution: the outer shell is triangular in shape and is inclined.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this invention, by adjusting the height of the pressure plate, the translational distance of the two smoothing rollers is adjusted. This allows the smoothing rollers to not only smooth the material but also maintain pressure on both sides of the material after the pressure plate is pressed against it. The height of the pressure plate can be flexibly adjusted according to the different lengths of the material, thus achieving efficient smoothing treatment for materials of different lengths. When the pressure plate is higher, the contact time with the material is longer, and the distance the two smoothing rollers move is also longer, and vice versa, thus achieving the effect of positioning edges. This adjustment method not only improves the flatness of the processed material.

[0017] 2. In this invention, the collection structure, with its curved surface in contact with the smoothing roller, effectively collects dust and impurities generated during the smoothing process. The opening at the top of the casing facilitates the discharge of collected dust and impurities, preventing their accumulation on the smoothing roller surface and thus maintaining the roller's cleanliness and ensuring stable smoothing results. This structure not only maintains a clean working environment but also reduces wear and tear on the equipment caused by dust and impurities, extending its service life and lowering maintenance costs.

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] Reference Figures 1-3 This utility model provides an embodiment of a pressure plate 7 mechanism with positioning edges, comprising a top plate 1, with mounting plates 5 fixedly connected to its four sides. The mounting plates 5 have threaded holes on their surfaces for fixing the entire mechanism to an external lifting platform, ensuring stability during operation. Two extension rods 2 are fixedly connected to the front and back of the top plate 1, respectively. Each extension rod 2 has a connecting rod 3 rotatably connected to its surface. A smoothing roller 4 is rotatably connected to the bottom end of each connecting rod 3. There are two sets of connecting rods 3, with two connecting rods 3 in each set. Fixing plates 9 are fixedly connected to the outer surfaces of the two connecting rods 3. The two ends of springs 10 are fixedly connected to adjacent sides of the two fixing plates 9. There are two smoothing rollers 4, elastically connected by springs 10. This elastic connection method can adapt to materials of different thicknesses, ensuring that the smoothing rollers 4 maintain good contact with the material during the smoothing process. A pressure plate 7 is located below the top plate 1, used to press the material firmly, ensuring stability during smoothing and preventing material movement or deformation.

[0026] Reference Figure 2 The pressure plate 7 is provided with an adjustment structure 6, which includes a threaded rod 602. A knob 601 is fixedly connected to the top of the threaded rod 602. The threaded rod 602 is threaded through the top of the top plate 1. The bottom of the threaded rod 602 is rotatably connected to a connecting plate 603 through a bearing. The bottom of the connecting plate 603 contacts the top of the pressure plate 7. The four corners of the top of the connecting plate 603 are threadedly connected to the top of the pressure plate 7 through bolts A606. The bottom of the connecting plate 603 is detachably connected to the top of the pressure plate 7. This detachable connection method facilitates the replacement or maintenance of the pressure plate 7. A guide rod 604 is fixedly connected to the top of the connecting plate 603. The top end of the guide rod 604 extends through the bottom of the top plate 1. A limit plate 605 is fixedly connected to the top end of the guide rod 604. There are two guide rods 604 and two limit plates 605, which are symmetrically arranged on the top of the pressure plate 7. The function of the guide rods 604 and the limit plates 605 is to ensure that the pressure plate 7 remains stable during up and down movement and to prevent the pressure plate 7 from shifting. A collecting structure 8 is provided on the connecting rod 3.

[0027] Reference Figure 3 , Figure 4The collecting structure 8 includes an extension plate 803, which is fixedly connected to the outside of the connecting rod 3. The inner side of the extension plate 803 contacts the outer shell 801. The front and back sides of the outer shell 801 are respectively provided with threaded grooves 802. The outer wall of the extension plate 803 is threadedly connected to the inner wall of the threaded groove 802 by bolts B804. This connection method facilitates the installation and disassembly of the outer shell 801, and is convenient for cleaning and maintenance. The top of the outer shell 801 is provided with an opening. The side of the outer shell 801 near the smoothing roller 4 is provided with an arc surface that contacts the outer surface of the smoothing roller 4. The outer shell 801 is triangular and inclined, so that the outer shell 801 can effectively collect the dust and impurities attached to the smoothing roller 4 during the smoothing process, prevent the dust and impurities from accumulating on the surface of the smoothing roller 4, thereby keeping the smoothing roller 4 clean and ensuring the smoothing effect.

[0028] Working Principle: The mechanism is fixed to an external lifting platform via mounting plate 5, and the up-and-down movement of the lifting platform drives the entire mechanism. During operation, the material to be processed is first placed on the worktable, ensuring it is flat and correctly positioned. By rotating knob 601, the threaded rod 602 is adjusted to move up and down, thereby moving the pressure plate 7 up and down, thus adjusting the height of the pressure plate 7. This adjustment method allows the pressure plate 7 to adapt to materials of different lengths, ensuring that the smoothing roller 4 effectively contacts and smooths the material throughout its entire length.

[0029] When the pressure plate 7 presses down and comes into contact with the material, the smoothing roller 4, supported by the elasticity of the spring 10, keeps the material pressed against both sides. As the pressure plate 7 moves up and down, the smoothing roller 4 rolls along the material surface, smoothing the material. The higher the pressure plate 7, the longer the smoothing roller 4 is in contact with the material and the longer it moves, and vice versa. This allows for efficient smoothing of materials of different lengths, providing a positioning edge effect. Throughout the processing, the elastic connection of the smoothing roller 4 can adapt to materials of different thicknesses, ensuring the stability and consistency of the smoothing effect. Through this design, the device not only improves the flatness of the processed material but also enhances the versatility and flexibility of the mechanism, making it suitable for various material processing scenarios and significantly improving production efficiency and processing quality.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
