Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hardware transportation, in particular to a transfer device for hardware production workshop. BACKGROUND

[0002] According to the search, the invention patent disclosed in CN119059218A relates to the technical field of hardware product transfer equipment, specifically a hardware product processing transfer equipment, which comprises a cleaning mechanism for cleaning the debris on the surface of the transfer main body, the cleaning mechanism comprises a hollow rotating rod, a plurality of through grooves are formed through the surface of the hollow rotating rod, a scraper is slidably connected in the through groove, a hollow cylinder is arranged in the hollow rotating rod, and two driving grooves are formed on the surface of the hollow cylinder; the vibration mechanism can vibrate the hollow rotating rod, the vibration mechanism comprises a driven rod, a plurality of equidistantly arranged discs are sleeved on the surface of the driven rod, an annular groove is formed on the surface of the disc, a plurality of V-shaped grooves are symmetrically formed on the surface of the annular groove, a plurality of equidistantly distributed rollers are slidably connected on the surface of the annular groove and the V-shaped groove, and a top rod is movably connected on the surface of the roller. Through the cooperation between the various parts, the debris falling on the surface of the transfer main body can be cleaned, and the transfer efficiency of the hardware parts is ensured.

[0003] The above-mentioned patent still has some deficiencies in actual use. The scraper is mostly made of metal or hard plastic material, and when it directly contacts the surface of the conveying belt, it will generate a large friction force. When the conveying belt is running, the hard scraper continuously scrapes the surface of the belt, which not only accelerates the wear of the rubber layer of the conveying belt and reduces its tensile strength, but also may form scratches on the surface of the belt, which become new embedding points of the debris and form a vicious cycle of "wear-embedding debris-accelerating wear".

[0004] In addition, the cleaning method of the scraper lacks flexibility adjustment ability. For firmly adhered metal debris, the pressure of the scraper needs to be increased to remove it, but this will further aggravate the mechanical damage to the conveying belt. For loose debris, excessive scraping will cause unnecessary wear. At the same time, the scraper cannot adapt to conveying belts of different materials and different thicknesses, and has poor universality. Moreover, the scraper itself will also be worn out after long-term use, which will reduce the cleaning efficiency and need to be replaced frequently, increasing the production downtime and maintenance cost.

[0005] Based on this, the present application discloses a transfer device for hardware production workshop. SUMMARY

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0031] The existing hardware products are manufactured on processing equipment, and need to be transferred to a specified position. Generally, a conveyor 1 is used to convey the hardware products. However, some metal scraps or other impurities will be left on the processed hardware products, which will directly adhere to the conveyor 1, causing damage to the conveyor 1 and affecting the long-term conveying of the conveyor 1.

[0032] Therefore, the present application provides a transfer device for a hardware production workshop, which is shown inFigure 1 - Figure 9 As shown, it includes a conveyor 1, on which a drive mechanism is provided. The drive mechanism includes a mounting box 301 and a drive assembly. Inside the mounting box 301 is a cleaning mechanism driven by the drive assembly. The cleaning mechanism includes a mounting frame 402. Two first rotating shafts 405 are rotatably connected to the mounting frame 402. A connecting plate 401 is fixedly installed at the close end of each of the two first rotating shafts 405. An arc plate 410 is fixedly installed between the two connecting plates 401. Several hollow tubes 408 are fixedly installed on the arc plate 410. The hollow tubes 408 are filled with magnetorheological fluid 409.

[0033] An electromagnet 403 is fixedly installed between the two connecting plates 401. The magnetic force of the electromagnet 403 is controlled by a controller. As the magnetic force of the electromagnet 403 changes, the hardness of the hollow tube 408 is changed.

[0034] For details, see Figure 2 and Figure 6 As shown, the drive assembly includes a perforated plate 302, which is fixedly connected to the mounting box 301. A positioning box 306 is fixedly mounted on the perforated plate 302. A dual-axis motor 308 is fixedly installed inside the positioning box 306. A sliding tube 304 is fixedly mounted on the power output shaft at the top of the dual-axis motor 308. A sliding column 303 is slidably connected inside the sliding tube 304. The sliding column 303 is fixedly connected to the mounting bracket 402.

[0035] During operation, after the hardware products are manufactured on the processing equipment, they need to be rotated to a designated position. The manufactured hardware products are then placed into conveyor 1, which is started to transport them. However, some metal shavings or other impurities remain on the processed hardware products. These shavings or impurities adhere directly to conveyor 1, causing damage and affecting its long-term transport capacity. Therefore, when conveyor 1 starts working, the dual-shaft motor 308 is activated. The sliding tube 304 rotates, which in turn drives the sliding column 303 to rotate. The sliding column 303 then drives the mounting frame 402 to rotate, which in turn drives the connecting plate 401 and the hollow tube 408 to rotate together. This allows for a rotary cleaning of the conveyor belt on the conveyor 1. Because it is a rotary cleaning process, the hollow tube 408 can clean at different angles. When some debris gets embedded in the conveyor belt of the conveyor 1, the hollow tube 408 can clean it from different angles, thus removing the debris more effectively.

[0036] Since the electromagnet 403 is controlled by the controller, the magnetic force can be adjusted according to the needs. When the magnetic force becomes larger, the magnetic flow rheological fluid 409 will be hardened due to the action of the magnetic force, so that the overall structure of the hollow tube 408 will increase in hardness, forming a hard bristle. The hard bristle can exert a larger pressure and friction force on the surface of the conveyor belt, which is good for removing tightly adhered and difficult-to-clean debris. It can also better clean embedded debris. When the magnetic force becomes smaller, the magnetic flow rheological fluid 409 will also soften, so that the overall structure of the hollow tube 408 will decrease in hardness, forming a soft bristle. The soft bristle is relatively soft and has a smaller friction force on the surface of the conveyor belt, which is suitable for cleaning debris that is relatively loose and easy to fall off. In this way, the hardness of the hollow tube 408 can be controlled according to the actual situation of the debris. When it needs to be hardened, it will be hardened. When it needs to be softened, it will be softened. The hollow tube 408 can clean the conveyor belt on the conveyor 1 in the best state, reducing the wear of the hollow tube 408 on the conveyor belt on the conveyor 1.

[0037] Further, if the hardware product is similar to an iron hardware product, it can be magnetically attracted. After the hollow tube 408 cleans the debris and other impurities remaining on the conveyor belt on the conveyor 1, part of the falling impurities will be attracted by the electromagnet 403. These impurities that are attracted can be recycled later. Impurities that are not attracted cannot be used continuously and remain on the perforated plate 302 for subsequent processing. When the electromagnet 403 is turned off, the magnetic force disappears, and the debris will automatically fall off, facilitating discharge.

[0038] Further, referring to Figure 6 , the driving mechanism further includes a fan blade 309 located below the positioning box 306 and fixedly connected to the power output shaft at the bottom end of the double-shaft motor 308.

[0039] When the double-shaft motor 308 starts to work and drives the sliding tube 304 to rotate, the fan blade 309 will also rotate, so that the fan blade 309 will continuously draw air downward. When the hollow tube 408 cleans the impurities on the conveyor belt on the conveyor 1 and falls off, it will be guided by the wind force and fall onto the perforated plate 302 to be collected. The air suction can also assist in cleaning the impurities, so that the impurities on the conveyor belt on the conveyor 1 can be better cleaned.

[0040] Among them, referring to Figure 2 and Figure 7As shown, the drive mechanism also includes a first connecting ring 508, which is rotatably mounted on the sliding column 303. A first auxiliary frame 504 is fixedly mounted on the first connecting ring 508. Several first locking teeth 506 are fixedly mounted on the top of the first auxiliary frame 504. A second gear 407 is provided above the first auxiliary frame 504. A second rotating shaft 406 is fixedly mounted on the second gear 407. The second rotating shaft 406 is rotatably connected to the mounting frame 402. The first gear 404 meshes with the second gear 407. The first gear 404 and the second gear 407 mesh.

[0041] The drive mechanism also includes a connecting box 501, which is fixedly connected to the mounting box 301. A slide rod 502 is fixedly installed inside the connecting box 501. A slider 503 is slidably connected to the slide rod 502. A first spring 505 is sleeved on the slide rod 502. One end of the first spring 505 is fixedly connected to the slider 503, and the other end of the first spring 505 is fixedly connected to the slide rod 502.

[0042] During operation, when the dual-axis motor 308 starts, it causes the mounting bracket 402 to rotate. The rotation of the mounting bracket 402 drives the second gear 407 and the first gear 404 to rotate together. In this way, the second gear 407 rotates under the action of the first locking tooth 506. The rotation of the second gear 407 causes the first gear 404 to rotate. The rotation of the first gear 404 drives the connecting plate 401 to rotate. The rotation of the connecting plate 401 drives the hollow tube 408 to rotate. In this way, the hollow tube 408 can continuously rotate around the sliding column 303 and also continuously rotate around the first rotating shaft 405. Thus, while the hollow tube 408 is cleaning the conveyor belt of the conveyor 1 by rotating around the sliding column 303, it further rotates to clean the impurities on the conveyor belt of the conveyor 1. It can better clean some waste embedded in the conveyor belt.

[0043] Among them, see Figure 3 and Figure 8 and Figure 9 As shown, a plurality of first extrusion balls 507 are fixedly installed at the bottom of the first auxiliary frame 504;

[0044] A compression mechanism is fixedly installed on the sliding tube 304. The compression mechanism includes a second connecting ring 601. Multiple compression columns 603 are fixedly installed on the second connecting ring 601. The compression columns 603 are fixedly connected to the sliding tube 304. Multiple compression components are slidably connected to the second connecting ring 601.

[0045] When the double-shaft motor 308 starts to rotate, the sliding tube 304 is driven to rotate, the sliding tube 304 drives the second connecting ring 601 to rotate through the extrusion column 603, so that the extrusion assembly is also rotated, and the extrusion assembly rotates to extrude the first extrusion ball 507. Because the plurality of first extrusion balls 507 are arranged at intervals, after being extruded by the extrusion assembly, the first auxiliary frame 504 will fluctuate up and down continuously, so that the hollow tube 408 can fluctuate up and down continuously when the impurities are transported on the double-rotating cleaning conveyor 1. The up-and-down fluctuation and vibration can produce more intense mechanical vibration on the surface of the conveyor belt, so that the waste chips adhered to the surface of the conveyor belt and embedded in the conveyor belt are more easily loosened and fallen off. For some stubborn and difficult-to-clean waste chips, the vibration can increase the relative motion and friction between the hollow tube 408 and the waste chips, thereby improving the cleaning effect.

[0046] As shown in Figure 8 and Figure 9 , the extrusion assembly comprises a fixed tube 604, the fixed tube 604 is in sliding connection with the second connecting ring 601, the bottom of the fixed tube 604 is threadedly connected with a screw rod 611, the top of the screw rod 611 is rotatably connected with a second extrusion ball 602, and the second extrusion ball 602 is located inside the fixed tube 604 and is in sliding connection with the fixed tube 604.

[0047] When working, the position of the second extrusion ball 602 can be controlled by rotating the screw rod 611. The distance of the second extrusion ball 602 moving out of the fixed tube 604 is the range of the second connecting ring 601 fluctuating up and down. Thus, the fluctuation range of the second connecting ring 601 can be adjusted according to actual needs, so that the hollow tube 408 can better clean the impurities and reduce the wear on the conveyor belt on the conveyor 1.

[0048] As shown in Figure 8 and Figure 9 , the extrusion assembly further comprises a U-shaped tube 605, the inside of one end of the U-shaped tube 605 is in sliding connection with a second extrusion rod 608, one end of the second extrusion rod 608 is fixedly connected with a fixed plate 610, the other end of the second extrusion rod 608 is connected with the U-shaped tube 605 through a third spring 609, the inside of the other end of the U-shaped tube 605 is in sliding connection with a first extrusion rod 606, and the first extrusion rod 606 is connected with the U-shaped tube 605 through a second spring 607. The interiors of the plurality of U-shaped tubes 605 are filled with liquid, and the amounts of the liquid in the interiors of the plurality of U-shaped tubes 605 decrease successively.

[0049] The extrusion assembly further comprises a rotating disc 307, the rotating disc 307 is in rotational connection with a positioning box 306, and the positioning box 306 is threadedly connected with a threaded disc 305.

[0050] When working, by rotating the threaded disc 305, the threaded disc 305 can be constantly moved downwards, so that the threaded disc 305 can extrude the first extrusion rod 606. Since the amount of liquid stored in the plurality of U-shaped tubes 605 is different and decreases in turn, the order in which the liquid acts on the second extrusion rod 608 is also in turn decreasing order, so that the order in which the plurality of second extrusion rods 608 moves upwards is also in turn, so that it can effectively control whether the plurality of second extrusion balls 602 extends to the first auxiliary frame 504 to interact with the first extrusion ball 507. The more second extrusion balls 602 interact with the first extrusion ball 507, the faster the frequency of vibration of the first auxiliary frame 504 will be, and vice versa, so that it can effectively control the cleaning of the hollow tube 408 on the conveyor 1 according to the actual needs.

[0051] As shown in Figure 1 The bottom of the installation box 301 is fixedly connected with two connecting seats 2, the connecting seat 2 is slidably connected with the conveyor 1, and is fixed with the connecting seat 2 through bolts.

[0052] In summary, the problems of easy damage, single cleaning method, inconvenience of scrap collection and severe wear of the existing conveyor 1 due to metal scrap residues are effectively solved.

[0053] Working principle:

[0054] First, place the hardware products on the conveyor 1, start the conveyor 1 to start conveying the hardware products.

[0055] Synchronously start the double-shaft motor 308, the top power output shaft drives the sliding pipe 304 to rotate clockwise, the sliding pipe 304 drives the mounting frame 402 to rotate through the sliding column 303 slidably connected inside, and then the connecting disc 401 and the hollow tube 408 make circular motion around the sliding column 303 as the axis, and the surface of the conveying belt is rotated and cleaned, covering different angles to remove embedded scrap.

[0056] The controller adjusts the magnetic force of the electromagnet 403 according to the type of scrap, such as loose or tightly adhered. When the magnetic force increases, the magnetorheological fluid 409 is hardened under the action of the magnetic field, and the hollow tube 408 becomes a "hard bristle" for removing tightly adhered or embedded scrap. When the magnetic force decreases, the magnetorheological fluid 409 softens, and the hollow tube 408 becomes a "soft bristle" for cleaning loose scrap and reducing wear on the conveying belt.

[0057] The bottom power output shaft of the double-shaft motor 308 drives the fan blade 309 to rotate counterclockwise, generating downward air suction force, guiding the scrap cleaned by the hollow tube 408 to the upper part of the hollow plate 302 for centralized collection. Ferromagnetic scrap will be attracted by the electromagnet 403, and non-ferromagnetic scrap will fall onto the hollow plate 302. After the electromagnet 403 is turned off, the attracted scrap automatically falls off for recycling.

[0058] When the mounting bracket 402 rotates, it drives the second gear 407 to mesh with the first gear 404 and rotate. Under the intermittent meshing action of the first locking tooth 506 on the top of the first auxiliary bracket 504, the second gear 407 drives the first gear 404 to drive the connecting plate 401 to rotate around the first rotating shaft 405. At this time, the hollow tube 408 simultaneously realizes the compound motion of "revolving around the sliding column 303" and "rotating around the first rotating shaft 405", which enhances the scraping and peeling effect on embedded waste.

[0059] When the sliding tube 304 rotates, it drives the second connecting ring 601 to rotate synchronously through the extrusion column 603. The extrusion assembly installed on the second connecting ring 601 includes the fixed tube 604 and the second extrusion ball 602, which periodically extrudes the first extrusion ball 507 at the bottom of the first auxiliary frame 504. Since the first extrusion balls 507 are distributed at intervals, the first auxiliary frame 504 will fluctuate up and down, causing the hollow tube 408 to generate high-frequency vibration, which causes the adhering waste to loosen and fall off due to mechanical vibration.

[0060] Rotating the screw 611 can control the length of the second extrusion ball 602 extending out of the fixed tube 604, thereby adjusting the fluctuation range of the second connecting ring 601 to adapt to conveyor belts of different thicknesses or the amount of waste.

[0061] Rotate the threaded disc 305 to move it downwards, squeezing the first squeezing rod 606. As the amount of liquid in the U-shaped tube 605 decreases sequentially, the liquid pressure is transmitted to the second squeezing rod 608 in sequence, controlling the number of interactions between the multiple second squeezing balls 602 and the first squeezing ball 507. The more second squeezing balls 602 that participate in the action, the higher the vibration frequency of the first auxiliary frame 504, achieving high-intensity cleaning of stubborn waste.

[0062] First, turn off the dual-shaft motor 308. After the hollow tube 408, fan blades 309 and other moving parts have completely stopped, turn off the conveyor 1 to avoid the accumulation of residual waste during equipment shutdown.

[0063] The mounting box 301 is slidably connected to the conveyor 1 via the bottom connecting seat 2. After being adjusted to a suitable position, it is tightened with bolts to ensure that the device remains stable when running at high speed and to prevent the components from loosening due to vibration.
