Description

Technical Field

[0001] This utility model relates to the field of metal filter screen straightening technology, specifically a straightening device for metal filter screen production. Background Technology

[0002] Metal filter screen straightening devices are used to restore deformed filter screens to a flat state. However, existing devices have certain drawbacks. For example, CN209647282U describes a straightening device for metal filter screen production, which includes a workbench and four mounting brackets. The four mounting brackets are fixed to the outer wall of the workbench via a movable structure, and each mounting bracket is equipped with a fastening structure. The movable structure includes a pair of slide rails and a pair of drive units. The pair of slide rails are embedded in the surface of the workbench, and the pair of drive units are fixed inside the workbench. Four telescopic motors are fixed to the four mounting brackets.

[0003] Although the above-mentioned device can correct the shape of the metal filter screen, the correction process is relatively complicated. For thicker metal filter screens, the filter screen itself has greater rigidity, and it is difficult and unsuitable to use the method of overall compression and expansion. It is necessary to use a local flattening method for correction. Utility Model Content

[0004] The purpose of this invention is to provide a straightening device for the production of metal filter screens, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A shaping device for producing metal filter screens includes a base plate, a top plate fixedly connected above the base plate, a fixing frame fixedly connected above the top plate, and an electric push rod fixedly connected to the upper surface of the fixing frame.

[0007] A guide module is fixedly connected to the upper surface of the base plate. The guide module includes a guide rail, a first sliding frame, a second sliding frame, and a double-ended lead screw. The guide rail is fixedly connected to the upper surface of the base plate. The first sliding frame is slidably connected to the inside of the guide rail. The second sliding frame is slidably connected to the inside of the guide rail. The double-ended lead screw is rotatably connected to the inner side of the guide rail.

[0008] Two flattening modules are provided above the base plate. Each flattening module includes a mounting base and a rotating roller. There are several mounting bases, which are respectively fixedly connected to the lower surface of the top plate and the upper surface of the base plate. The rotating roller is rotatably connected to the inner surface of the mounting base, and an extrusion belt is nested on the outer surface of the rotating roller.

[0009] Furthermore, the lower surface of the base plate is fixedly connected to a screw seat near each of the four corners, and the lower surface of the screw seat is threaded with a leveling seat foot.

[0010] Furthermore, the outer surfaces of both the first and second sliding frames are movably connected with universal balls, and the second and first sliding frames are threadedly connected to a double-ended lead screw.

[0011] Furthermore, the flattening module also includes a baffle and a distribution roller. The baffle is fixedly connected to the outer surface of the mounting base, and the distribution roller is rotatably connected to the inner surface of the baffle. A servo motor is fixedly connected to the outer surface of the baffle, and the output end of the servo motor is fixedly connected to the rotating roller.

[0012] Furthermore, the outer surface of the baffle is threaded with a first bolt, and the baffle is fixedly connected to the mounting base by the first bolt.

[0013] Furthermore, the upper surface of the fixing frame is embedded with a mounting column, the mounting column penetrates the baffle, and the output end of the electric push rod is fixedly connected to the top plate.

[0014] Furthermore, the outer surface of the mounting column is threaded with a second bolt, and the mounting column is fixedly connected to a baffle near the base plate by the second bolt.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Slide the metal filter screen between the two flattening modules along the first and second sliding frames. Use an external electric wrench to rotate the double-ended screw to change the position of the first and second sliding frames under the push of the thread. This guides and limits the metal filter screen when it enters between the two flattening modules, preventing the filter screen from shifting when entering and affecting the correction effect.

[0017] 2. During the process of the filter screen entering between the two flattening modules, the servo motor of the upper flattening module is activated. The output of the servo motor drives one of the rotating rollers to rotate. The rotating roller drives the extrusion belt to run. The upper extrusion belt squeezes the filter screen and applies an outward force to the filter screen, so that the filter screen moves in conjunction with the extrusion belt located on the lower flattening module. This achieves the correction of the filter screen from local to overall, ensuring the correction effect of the filter screen. In addition, the distribution roller contacts the inner surface of the extrusion belt, sharing the reaction force on the extrusion belt, making the force on the filter screen more uniform.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0024] Please see Figure 1-4 In this embodiment of the utility model, a straightening device for producing metal filter screens includes a base plate 1, a top plate 5 fixedly connected above the base plate 1, a fixing frame 602 fixedly connected above the top plate 5, and an electric push rod 603 fixedly connected to the upper surface of the fixing frame 602.

[0025] A guide module 2 is fixedly connected to the upper surface of the base plate 1. The guide module 2 includes a guide rail 201, a first sliding frame 202, a second sliding frame 203, and a double-ended lead screw 205. The guide rail 201 is fixedly connected to the upper surface of the base plate 1. The first sliding frame 202 is slidably connected to the inside of the guide rail 201. The second sliding frame 203 is slidably connected to the inside of the guide rail 201. The double-ended lead screw 205 is rotatably connected to the inner side of the guide rail 201.

[0026] Two flattening modules 3 are provided above the base plate 1. The flattening module 3 includes a mounting base 301 and a rotating roller 302. There are several mounting bases 301, which are fixedly connected to the lower surface of the top plate 5 and the upper surface of the base plate 1 respectively. The rotating roller 302 is rotatably connected to the inner surface of the mounting base 301. An extrusion belt 306 is nested on the outer surface of the rotating roller 302.

[0027] Specifically, during use, the metal filter screen is manually slid into the space between the two flattening modules 3 along the first sliding frame 202 and the second sliding frame 203. An external electric wrench is used to rotate the double-ended screw 205, which changes the position of the first sliding frame 202 and the second sliding frame 203 under the push of the screw. This guides and limits the metal filter screen as it enters the space between the two flattening modules 3, preventing the filter screen from shifting during entry and affecting the correction effect. The electric push rod 603 is then activated, causing one of the flattening modules 3 to descend, changing the distance between the two extrusion bands 306. This allows the device to be used with filter screens of different thicknesses, expanding the applicability of the device.

[0028] Example 1

[0029] like Figure 1-4 As shown, engagement seats 101 are fixedly connected to the lower surface of the base plate 1 near the four corners, and leveling feet 102 are threadedly connected to the lower surface of the engagement seats 101.

[0030] In this embodiment, the leveling foot 102 can be manually rotated to extend downwards under the push of the thread, which facilitates the leveling operation of the device.

[0031] like Figure 1-4 As shown, universal balls 204 are movably connected to the outer surfaces of sliding frame 202 and sliding frame 203, and sliding frame 203 and sliding frame 202 are threadedly connected to double-ended lead screw 205.

[0032] In this embodiment, the distance between the first sliding frame 202 and the second sliding frame 203 is adjusted by the double-ended lead screw 205, and the metal filter screen and the universal ball 204 are in contact, reducing the friction force on the metal filter screen during the guiding process.

[0033] Example 2

[0034] Based on Example 1, in order to overcome the problem that it is inconvenient to correct filters of different thicknesses in Example 1.

[0035] like Figure 1-4 As shown, the flattening module 3 also includes a baffle 304 and a sharing roller 305. The baffle 304 is fixedly connected to the outer surface of the mounting base 301, and the sharing roller 305 is rotatably connected to the inner surface of the baffle 304. A servo motor 4 is fixedly connected to the outer surface of the baffle 304. The output end of the servo motor 4 is fixedly connected to the rotating roller 302. A first bolt 303 is threadedly connected to the outer surface of the baffle 304. The baffle 304 is fixedly connected to the mounting base 301 through the first bolt 303.

[0036] In this embodiment, during the process of the filter screen entering between the two flattening modules 3, the servo motor 4 is only installed on the upper flattening module 3. When the servo motor 4 is started, its output end drives one of the rotating rollers 302 to rotate. The rotating roller 302 drives the extrusion belt 306 to run. The upper extrusion belt 306 extrudes the filter screen and applies an outward force to it, causing the filter screen to move in coordination with the extrusion belt 306 located on the lower flattening module 3. This achieves the correction of the filter screen from local to overall, ensuring the correction effect of the filter screen. In addition, the sharing roller 305 contacts the inner surface of the extrusion belt 306, sharing the reaction force on the extrusion belt 306, making the force on the filter screen more uniform.

[0037] like Figure 1-4 As shown, a mounting post 6 is embedded and fixedly connected to the upper surface of the fixing frame 602. The mounting post 6 passes through the baffle 304. The output end of the electric push rod 603 is fixedly connected to the top plate 5. A second bolt 601 is threadedly connected to the outer surface of the mounting post 6. The mounting post 6 is fixedly connected to the baffle 304 near the bottom plate 1 by the second bolt 601.

[0038] In this embodiment, the fixing frame 602 and the mounting column 6, together with the second bolt 601 and the lower baffle 304, form a stable whole. At this time, the electric push rod 603 is activated. The output end of the electric push rod 603 applies a downward force to the flattening module 3 on the top plate 5 through the top plate 5. At the same time, the mounting column 6 guides the moving baffle 304. The distance between the two flattening modules 3 can be changed by the electric push rod 603, thereby improving the adaptability of the device to filters of different thicknesses.
