Description

Technical Field

[0001] This invention relates to the field of color coating technology, specifically to a multi-layer reciprocating energy-saving color coating production line. Background Technology

[0002] A color coating production line is an automated production line used to produce color-coated products. It consists of multiple workstations and machines used to complete various production stages of color-coated products. Currently, most production lines use a single-layer feeding machine design, which means that the machine must stop when the roll material is exhausted, making it impossible to achieve cyclic feeding operation.

[0003] Among the many existing technologies, Chinese patent CN115318523A discloses a steel plate color coating production line that facilitates feeding. By setting a base plate, guide rail, limit wheel, support block, support plate, rubber plate, support rod, fixing plate and spring, it realizes the convenient installation of steel plate coils on the feeding device, making feeding and installation more convenient.

[0004] However, its feeding device uses single-layer roll material feeding, which means that when the roll material is exhausted, the equipment needs to be stopped to replace the roll material, thus affecting production efficiency.

[0005] Based on this, the present invention designs a multi-layer reciprocating energy-saving color coating production line to solve the above problems. Summary of the Invention

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] The present invention will be further described below with reference to embodiments.

[0035] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-9 The device includes a main body 1, on which a double-layer roll material running drive assembly 2 is installed. A roll sleeve fixing assembly 3 is provided on the double-layer roll material running drive assembly 2 and connected to the main body 1. The double-layer roll material running drive assembly 2 includes a double-layer roll material assembly 21, a first running assembly 22, and a second running assembly 23.

The roll sleeve fixing assembly 3 is disposed on the double-layer roll material assembly 21.

[0036] It also includes a coil pressing and welding assembly 4, which is installed on the main body 1 of the equipment and is used to weld the two coils of the double-layer coil assembly 21.

[0037] The double-roll assembly 21 enables alternating reciprocating feeding. When one roll is exhausted, the other roll can take over to continue feeding, thus avoiding frequent shutdowns when the roll is exhausted. The first operating component 22 enables a single drive to feed the two rolls of the double-roll assembly 21. At the same time, the first operating component 22 also provides power to the second operating component 23, which transports the two rolls of the double-roll assembly 21. The roll fixing component 3 facilitates fixing the rolls of the double-roll assembly 21 when changing them, preventing the rolls from slipping. The roll pressing and welding component 4 enables the welding of the two rolls of the double-roll assembly 21. When one roll is exhausted, the exhausted roll is welded to the new roll, thus achieving uninterrupted production line operation when switching consumables.

[0038] In some embodiments, such as Figure 1-9 As shown, in a preferred embodiment of the present invention, the main body 1 of the equipment includes a base plate 11, a housing 12 and a mounting frame 13. The housing 12 and the mounting frame 13 are both fixedly installed on the base plate 11. The double-layer roll assembly 21, the first running assembly 22 and the second running assembly 23 are all installed on the housing 12. The roll pressing and welding assembly 4 is installed on the mounting frame 13 and the base plate 11. The roll sleeve fixing assembly 3 is connected to the housing 12.

[0039] The double-layer roll assembly 21 includes a first roll 211, a second roll 212, a first roller 213, a second roller 214, and a sleeve 215. The outer ends of the first roll 211 and the second roll 212 face opposite directions. The inner ends of the first roll 211 and the second roll 212 are fixedly connected to the outer ends of the sleeve 215. The inner ends of the two sleeves 215 are respectively sleeved on the first roller 213 and the second roller 214. The first roller 213 and the second roller 214 are both connected to the first running assembly 22. The fixing assembly 3 is connected to the sleeve 215.

[0040] The first operating component 22 includes a first drive disk 221, a second drive disk 222, a ratchet groove 224, a transmission ring 225, a first transmission wheel 226, a second transmission wheel 227, and a motor 228. The motor 228 is fixedly mounted on the housing 12. The output end of the motor 228 is fixedly connected to both the first drive disk 221 and the second drive disk 222. The output end of the motor 228 is also connected to the second operating component 23. Both the first drive disk 221 and the second drive disk 222 are hinged with pawls 223, and the two pawls 223 face opposite directions. There are two transmission rings 225, each with a ratchet groove 224 that engages with the two pawls 223. The transmission ring 225 on the first drive disk 221 is connected to the first transmission wheel 226 via a first belt, and the transmission ring 225 on the second drive disk 222 is connected to the second transmission wheel 227 via a second belt.

[0041] The second operating component 23 includes a third rotating roller 231, a fourth rotating roller 232, a fifth rotating roller 233, a main gear 234, a first driven gear 235, a second driven gear 236, and a pulley assembly 237. The third rotating roller 231, the fourth rotating roller 232, and the fifth rotating roller 233 are arranged vertically from top to bottom. The third rotating roller 231, the fourth rotating roller 232, and the fifth rotating roller 233 are all rotatably connected to the housing 12. The first driven gear 235, the main gear 234, and the second driven gear 236 are respectively fixedly installed on the third rotating roller 231, the fourth rotating roller 232, and the fifth rotating roller 233. The main gear 234 is meshed with the first driven gear 235 and the second driven gear 236. The fourth rotating roller 232 is connected to the output end of the motor 228 through the pulley assembly 237.

[0042] When the production line is running, one of the first roll 211 and the second roll 212 is put into production. When the first roll 211 is put into production, the motor 228 rotates, which drives the first drive disk 221 to rotate. At this time, the rotation direction of the first drive disk 221 is the same as the meshing direction of the pawl 223 and the ratchet groove 224 that the pawl 223 engages with. At this time, the first drive disk 221 drives the transmission ring 225 on it to rotate. The transmission ring 225 drives the first transmission wheel 226 to rotate through the first belt. The first transmission wheel 226 drives the first rotating roller 213 to rotate. The first rotating roller 213 drives the sleeve 215 that is used in conjunction with the first roll 211 to rotate through the sleeve fixing assembly 3. The sleeve 215 drives the second roll 212 to rotate.

[0043] Meanwhile, the output of motor 228 drives the fourth roller 232 to rotate via pulley assembly 237. The fourth roller 232 drives the first driven gear 235 to rotate, and the first driven gear 235 drives the second driven gear 236 and pulley assembly 237 to rotate. The second driven gear 236 and pulley assembly 237 drive the third roller 231 and the fifth roller 233 to rotate respectively. At this time, the third roller 231 and the fourth roller 232 reverse their directions. The third roller 231 and the fourth roller 232 push the first roll material 211 between them for transmission. Thus, motor 228 provides power for both the rotation and transportation of the roll material, achieving energy saving.

[0044] When the first roll 211 is exhausted, the last section of the first roll 211 slides past the third roller 231 and the fourth roller 232. Then the control motor 228 reverses. At this time, the first drive disc 221 cannot drive the transmission ring 225 that it works with to rotate, while the second drive disc 222 drives the transmission ring 225 that it works with to rotate. At this time, the transmission ring 225 drives the second roller 214 to rotate through the second belt. The second roller 214 drives the sleeve 215 that works with the second roll 212 to rotate through the sleeve fixing assembly 3.

[0045] The coil pressing and welding assembly 4 includes a pressing assembly 41 and a welding assembly 42. The pressing assembly 41 is mounted on the mounting frame 13, and the welding assembly 42 is mounted on the pressing assembly 41.

[0046] The pressing assembly 41 includes a cylinder 411, a first slider 412, a second slider 413, a third slider 414, a slide rod 415, a turntable 417, and a first connecting rod 418. The cylinder 411 is mounted on the base plate 11. The output end of the cylinder 411 is fixedly connected to the first slider 412. The first slider 412, the second slider 413, and the third slider 414 are all slidably connected to the slide rod 415. The slide rod 415 is fixedly mounted on the mounting bracket 13. A second spring 416 is fixedly connected between the second slider 413 and the third slider 414. The welding assembly 42 is mounted on the first slider 412 and the second slider 413. The turntable 417 is rotatably connected to the housing 12. One end of the first connecting rod 418 and the second connecting rod 419 are rotatably connected to the turntable 417. The other end of the first connecting rod 418 is rotatably connected to the third slider 414, and the other end of the second connecting rod 419 is rotatably connected to the first slider 412.

[0047] The welding assembly 42 includes an upper welding block 421 and a lower welding block 422, which are respectively fixedly installed on the second slider 413 and the first slider 412.

[0048] Simultaneously, motor 228 drives the fourth roller 232 to reverse direction via the second transmission wheel 227. At this time, the rotation directions of the fourth roller 232 and the fifth roller 233 are opposite. Simultaneously, the fourth roller 232 and the fifth roller 233 drive the second roll 212 to run. When the foremost end of the second roll 212 slides past the fourth roller 232 and the fifth roller 233, the foremost end of the second roll 212 overlaps vertically with the rear end of the first roll 211. This activates cylinder 411, which drives the first slider 412 to slide on slide rod 415. The first slider 412 then drives the first connecting rod 418 to move. 8 drives the turntable 417 to rotate, the turntable 417 drives the second connecting rod 419 to move, the second connecting rod 419 drives the third slider 414 to slide downward on the sliding rod 415, the third slider 414 compresses the second spring 416, the second spring 416 drives the second slider 413 to slide downward on the sliding rod 415 until the lower welding block 422 and the upper welding block 421, which are fixedly installed on the first slider 412 and the second slider 413, press and weld the second roll 212 and the first roll 211 together. Then the fourth roller 232 and the fifth roller 233 continue to push the second roll 212 to run on the production line equipment.

[0049] In some embodiments, such as Figure 1-9 As shown, in a preferred embodiment of the present invention, the sleeve fixing assembly 3 includes a fixing sleeve 31, an oil supply pipe 33, an oil supply groove 35, an oil storage groove 36, a pressing block 37, and a first spring 38. There are two fixing sleeves 31, which are fixedly installed on the housing 12. The two fixing sleeves 31 are respectively fitted onto the ends of the first rotating roller 213 and the second rotating roller 214. Each fixing sleeve 31 has a through hole 32, and the oil supply pipe 33 is fixedly connected to the through hole 32. The first rotating roller 213 and the second rotating roller 214... Both rollers have main gear ring grooves 34 that are connected to the through holes 32. The oil delivery grooves 35 are opened on the first roller 213 and the second roller 214. One end of the oil delivery grooves 35 is connected to the main gear ring grooves 34 and the other end is connected to the oil storage grooves 36. The oil storage grooves 36 are equally spaced on the outer walls of the first roller 213 and the second roller 214. The extrusion block 37 is slidably connected to the oil storage grooves 36. The first spring 38 is fixedly installed between the extrusion block 37 and the oil storage grooves 36. The oil delivery pipe 33 is connected to a hydraulic device.

[0050] When the first roll 211 or the second roll 212 is replaced, hydraulic oil is drawn from the oil supply pipe 33. The hydraulic oil flows from the oil reservoir 36 into the oil supply trough 35, then from the oil supply trough 35 into the main gear ring groove 34, and then from the main gear ring groove 34 into the through hole 32. Finally, it flows back to the hydraulic equipment through the oil supply pipe 33. At this time, the extrusion block 37 disengages from the inner end of the sleeve 215 under the action of the first spring 38, so that the sleeve 215 can be removed from the first roller 213 or the second roller 214. When a new first roll 211 or second roll 212 is installed, the sleeve 215 fixed to it is fitted onto the first roller 213 or the second roller 214. By injecting hydraulic oil in the opposite direction, the extrusion block 37 fixes the inner end of the sleeve 215. Thus, when the first roller 213 or the second roller 214 rotates, the extrusion block 37 drives the sleeve 215 to rotate, and the sleeve 215 drives the first roll 211 or the second roll 212 fixed to its outer end to rotate.
