Description

Technical Field

[0001] The utility model relates to the technical field of leveling devices, in particular to a leveling device for producing expanded metal mesh. Background Art

[0002] Expanded metal mesh is a commonly used material in the field of mechanical processing. When it leaves the factory, it is usually wound together in a large roll. When it is used, the expanded metal mesh of the required size is cut out from the roll. Since the expanded metal mesh is rolled, the cut sheet is also curled, and thus needs to be flattened by a flattening device.

[0003] The patent for a metal mesh leveling device with the announcement number CN213350629U includes a base, a main roller, an auxiliary roller, a motor, a reducer, a pulley, a belt, a gear, a screw, and a sleeve. Axle holes are provided at opposite positions on the left and right sides of the upper end of the base, and the main roller is provided in the axle hole. A mounting through-hole is provided above the base, and a threaded hole is provided on the base above the mounting through-hole. The threaded hole is matched with a screw, and a sleeve is provided at the lower end of the screw. The sleeve can wrap the two ends of the auxiliary roller. The first auxiliary roller, the second auxiliary roller, the third auxiliary roller, and the fourth auxiliary roller can be adjusted in distance from the main roller by the screw. The metal mesh leveling device of the utility model has a simple structure and a reasonable design. Through the cooperation of the auxiliary roller and the main roller, the metal mesh can be squeezed and leveled, and the leveling efficiency is high and the effect is good.

[0004] However, during the flattening process of the metal mesh, if foreign matter adheres to the pressing roller, it may cause periodic defects on the surface of the metal mesh, such as roller marks, roller patterns, roller indentations, etc. These defects not only affect the flatness of the metal mesh, but may also lead to a decline in product quality.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0023] like Figures 1 to 3 As shown, the utility model is a flattening device for producing expanded metal mesh, comprising: a flattening roller group 1, a cleaning component 2 for cleaning the upper and lower roller surfaces of the flattening roller group 1, a transmission component 3 for driving the cleaning component 2 to move the cleaning roller surface, and a collection component 4 for collecting the cleaned waste;

[0024] The cleaning assembly 2 includes: an upper sweeping brush plate 201 and a lower sweeping brush plate 202, a threaded rod 203 for driving the upper sweeping brush plate 201 and the lower sweeping brush plate 202 to move, the threaded rod 203 being rotatably mounted on the flattening device via bearings at both ends, and the surface of the threaded rod 203 being threadedly mounted on the middle portion of the corresponding upper sweeping brush plate 201 and the lower sweeping brush plate 202, and a guide rod 204 for guiding the moving upper sweeping brush plate 201 and the lower sweeping brush plate 202;

[0025] The transmission assembly 3 includes: a rotating shaft 302, a motor 301 that drives the rotating shaft 302 to rotate, the motor 301 is fixedly mounted on the flattening device through a mounting plate, a first bevel gear 303 is symmetrically fixedly mounted on the surface of the rotating shaft 302, a positioning block is symmetrically mounted on the surface of the rotating shaft 302, and one side of the positioning block is fixedly mounted on the flattening device. The setting of the positioning block further improves the stability of the rotation of the rotating shaft 302, and the second bevel gear 304 is fixed at the end of the threaded rod 203 and meshes with the surface of the first bevel gear 303.

[0026] During the process of flattening the metal expanded mesh by the flattening device, some metal scraps will adhere to the roller surface of the flattening roller, which may cause periodic defects on the surface of the metal expanded mesh, such as roller marks, roller patterns, roller indentations, etc. These defects not only affect the flatness of the metal mesh, but may also cause a decline in product quality. Therefore, by starting the motor 301, the output end of the motor 301 drives the two first bevel gears 303 on the surface of the rotating shaft 302 to rotate, so that the first bevel gear 303 is engaged with the second bevel gear 304 at one end of the corresponding threaded rod 203, so that the two threaded rods 203 respectively drive the corresponding upper sweeping brush plate 201 and the lower sweeping brush plate 202 to move, and when the flattening roller rotates, the upper sweeping brush plate 201 and the lower sweeping brush plate 202 sweep the surface of the flattening roller to sweep off the scraps attached to the surface of the flattening roller, thereby avoiding the scraps on the surface of the flattening roller causing periodic defects on the surface of the metal expanded mesh.

[0027] Two sets of guide rods 204 are provided, symmetrically slidably mounted on either side of the adjacent upper and lower sweeping brush plates 201 and 202. The ends of the guide rods 204 are fixedly mounted on the leveling device. Because the upper and lower sweeping brush plates 201 and 202 clean the surfaces of the rollers, they are relatively long. The symmetrically slidable guide rods 204 further enhance the stability of the movement of the upper and lower sweeping brush plates 201 and 202.

[0028] The collecting assembly 4 includes: an electromagnet 401 fixedly mounted on the lower sweeping brush plate 202, two electromagnets 401 are provided, and the two electromagnets 401 are symmetrically fixedly mounted on one side of the lower sweeping brush plate 202, an extrusion block 402 fixedly mounted on the lower sweeping brush plate 202, and a normally closed button switch 403 installed on the flattening device to cut off the power to the electromagnet 401, and an electrical connection between the normally closed button switch 403 and the electromagnet 401. When an external power supply is connected through the normally closed button switch 403, the electromagnet 401 generates magnetic attraction to absorb metal waste, and a collection box 404 for collecting waste on the surface of the electromagnet 401.

[0029] When the upper sweeping brush plate 201 and the lower sweeping brush plate 202 move to clean the upper and lower roller surfaces of the rolling device, the waste debris attached to the rollers falls off, and the two electromagnets 401 on one side of the lower sweeping brush plate 202 adsorb the fallen waste debris on its surface. When the lower sweeping brush plate 202 approaches the normally closed button switch 403, the extrusion block 402 on the surface of the lower sweeping brush plate 202 presses against the surface contact of the normally closed button switch 403, and the internal circuit of the normally closed button switch 403 is disconnected. At this time, the electromagnet 401 moves to the lower end of the collection box 404, and the electromagnet 401 no longer generates magnetic attraction. The waste debris on its surface falls into the collection box 404 for collection, thereby improving the cleanliness of the device.

[0030] Working principle: When the power is turned on and the flattening device for the production of expanded metal mesh is used, the motor 301 is started, and the output end of the motor 301 drives the two first bevel gears 303 on the surface of the rotating shaft 302 to rotate, so that the first bevel gear 303 is engaged with the second bevel gear 304 at one end of the corresponding threaded rod 203, so that the two threaded rods 203 respectively drive the corresponding upper sweeping brush plate 201 and lower sweeping brush plate 202 to move, and when the flattening roller rotates, the upper sweeping brush plate 201 and the lower sweeping brush plate 202 sweep the surface of the flattening roller to sweep away the waste chips attached to the surface of the flattening roller, thereby preventing the waste chips on the surface of the flattening roller from causing the surface of the expanded metal mesh to be damaged. Periodic defects occur. When the upper sweeping brush plate 201 and the lower sweeping brush plate 202 move to clean the upper and lower roller surfaces of the flattening device, the waste chips attached to the rollers fall down, and the two electromagnets 401 on one side of the lower sweeping brush plate 202 adsorb the fallen waste chips on its surface. When the lower sweeping brush plate 202 approaches the normally closed button switch 403, the extrusion block 402 on the surface of the lower sweeping brush plate 202 presses against the surface contact of the normally closed button switch 403, and the internal circuit of the normally closed button switch 403 is disconnected. At this time, the electromagnet 401 moves to the lower end of the collection box 404, and the electromagnet 401 no longer generates magnetic attraction, and the waste chips on its surface fall into the collection box 404 for collection.
