Description

Technical Field

[0001] The invention relates to the technical field of food can welding, in particular to a large food can welding device. Background Art

[0002] In food production, because the raw materials can be stored for a short period of time, and the space and energy consumption required for refrigeration are very huge, the commonly used storage method is canning. Canning means that after the raw materials are initially processed, they are placed in food cans for sealed storage. This not only consumes very little energy, but also takes up less space. However, in the production of food cans, manual welding is often inefficient due to their large size and large amount of welding, and the welding process is unstable. The Chinese utility model patent with announcement number CN21451856UA discloses a food can welding system. This prior art fixes the food can with a bracket and a support plate, and uses a motor and a slider to drive the welding gun to move, thereby realizing fixed track welding. However, this prior art cannot realize automated food can welding operations, and is not suitable for welding operations on large food cans. Summary of the invention

[0004] The metal coil is placed in the coil feeding device, and the metal coil is sent into the can body device through the coil feeding device, and the metal tube is welded into the food can wall. Then the food can wall enters the cover welding device, and the can top is welded to the food can wall through the cover welding device, and then the food can bottom is welded through the bottom cover device to complete the welding of the entire food can.

[0006] Furthermore, the cutting mechanism includes a cutting frame fixedly mounted on a winding frame, a cutting electric cylinder fixedly mounted on the cutting frame, an upper cutter fixedly mounted on the top of the cutting electric cylinder, the upper cutter slidably mounted on the cutting frame, a lower cutter slidably mounted on the cutting frame, a cutter pulling rope is arranged between the lower cutter and the upper cutter, and the cutter pulling rope is wound around the cutting frame.

[0007] The metal coil is placed on the coil drum, and the roller motor rotates, and the roller gear and the outer coil roller are driven to rotate through the motor gear, thereby driving the inner transfer gear and the inner coil roller to rotate through the outer transfer gear and the transfer belt, thereby driving the metal coil forward through the outer coil roller and the inner coil roller. The metal coil passes through the slope and passes between the upper cutter and the lower cutter. The inner roll roller and the middle roller gear drive the inner roller gear and the inner rotating roller to rotate through the long transmission belt, and the inner rotating roller drives the inner roller transfer wheel to rotate, thereby driving the outer roller transmission wheel and the outer roller to rotate through the transmission belt. The metal coil will reach the inner rotating roller and the outer roller through the knife rope, and the metal coil is sent into the tank device through the rotation of the inner rotating roller and the outer roller. After a certain length of the metal coil is fed in, the cutting electric cylinder extends and drives the upper cutter to descend along the cutting frame. The upper cutter descends and drives the lower cutter to rise along the cutting frame through the knife rope, and the metal coil is cut into a specified length by the upper cutter and the lower cutter.

[0008] Furthermore, the tank device includes an outer cylinder fixedly mounted on the base frame, a discharge plate fixedly mounted on the outer cylinder, an inner frame fixedly mounted on the outer cylinder, a cylinder pushing electric cylinder fixedly mounted on the inner frame, a push rod fixedly mounted on the top of the cylinder pushing electric cylinder, a rotating card rotatably mounted on the push rod, a cylinder welding module fixedly mounted on the inner frame, a docking gear rotatably mounted on the outer cylinder, the docking gear meshes with the outer roller gear, three rotating rollers are rotatably mounted on the outer cylinder, rotating rollers are fixedly mounted with rotating roller gears, the rotating roller gears mesh with the docking gears, an inner roller rotatably mounted on the outer cylinder, an inner rotating gear fixedly mounted on the inner roller, the inner rotating gear meshes with the three rotating roller gears, and the metal coil becomes a cylindrical metal coil after being wound up.

[0009] The metal coil enters between the rotating roller and the inner roller. The rotation of the outer roller gear will drive the docking gear to rotate, thereby driving the rotating roller gear and the rotating roller to rotate, thereby driving the inner rotating gear and the inner roller to rotate. The metal coil is rolled into a cylinder along the inner wall of the outer cylinder through the rotating roller and the inner roller to form a cylindrical metal coil. Then the cylinder pusher electric cylinder extends, driving the push rod to push the cylindrical metal coil to slide forward along the outer cylinder. The push rod and the rotating clamp will clamp the cylindrical metal coil to prevent the cylindrical metal coil from rotating during the forward movement. As the cylindrical metal coil advances in the outer cylinder, the cylindrical metal coil is welded by the cylinder welding module. After welding, it enters the discharge plate and the welding cover device.

[0010] Furthermore, the welding cover device includes a flip electric cylinder fixedly installed on the transfer frame, the flip frame is rotatably installed on the top of the flip electric cylinder, the drag drum frame is rotatably installed on the flip frame, a can drum is placed on the drag drum frame, the drag drum frame and the transfer frame are rotatably installed, a transmission motor is fixedly installed on the transmission motor shaft, a lower transmission column is fixedly installed on the lower transmission column, a driving gear is fixedly installed on the lower transmission column, the lower transmission column and the transfer frame are rotatably installed, an upper transmission column is rotatably installed on the transfer frame, an external gear is fixedly installed on the upper transmission column, a flat transmission wheel is rotatably installed on the transfer frame, a flat toothed belt is wound around the flat transmission wheel, a driven gear is rotatably installed on the transfer frame, a transmission belt is wound around the driven gear and the driving gear, a number of convex columns are fixedly installed on the transmission belt, a number of toggle wheels are rotatably installed on the transfer frame, a toggle gear is fixedly installed on the toggle wheel, the toggle gear is meshed with the flat toothed belt, a fixed side plate is fixedly installed on the transfer frame, and a cover feeding mechanism is arranged next to the transfer frame.

[0011] Furthermore, a bent column is slidably installed in the lower transmission column, and the bent column is slidably installed with the upper transmission column.

[0012] Furthermore, the cover feeding mechanism includes a stand, which is placed on the ground, with a cylinder shell fixedly installed on the stand, a cover welding module fixedly installed on the stand, a tank cover placed in the cylinder shell, a sliding column fixedly installed on the stand, a blocking frame slidably installed on the sliding column, a return spring arranged between the blocking frame and the stand, and an upper blocking block and a lower blocking block arranged on the blocking frame.

[0013] The cylindrical metal roll after welding becomes a can and falls onto the can drag rack. The contraction of the flip electric cylinder drives the flip rack to rotate, thereby driving the can drag rack to rotate along the transfer rack, thereby flipping the can to the outside of the convex column of the transmission belt. The rotation of the transmission motor drives the lower transmission column and the driving gear to rotate. The rotation of the driving gear drives the transmission belt to transport the can. At the same time, the lower transmission column rotates, driving the bending column to rotate, and the sliding of the bending column in the lower transmission column and the upper transmission column drives the upper transmission column to rotate, thereby driving the outer gear to rotate, thereby driving the flat toothed belt to rotate, thereby driving the toggle gear and the toggle wheel to rotate together. When the can moves on the transmission belt, the other side contacts the fixed side plate. The rotation of the toggle wheel makes the can rotate at the same time as it moves with the transmission belt. When the can reaches the bottom of the cylinder shell, The can barrel will squeeze the blocking frame, causing the blocking frame to slide inward along the sliding column, and the reset spring will be squeezed, causing the can cover originally located on the lower blocking block to fall onto the can barrel. At the same time, the upper blocking block will block the next can cover to prevent it from falling. Then the can barrel continues to move forward, driving the can cover to move forward together. The can barrel and the can cover rotate while moving forward. When passing the cover welding module, the can cover and the can barrel are welded. Since the can cover and the can barrel are rotating, a circle of welds on the can cover and the can barrel are welded. When the can barrel leaves the blocking frame, the reset spring begins to rebound, driving the blocking frame to slide outward, so that the upper blocking block no longer blocks the next can cover, and the can cover falls onto the lower blocking block to prepare for the next welding. After the welding is completed, the transmission belt will transport the can barrel to the transfer rack and finally enter the bottom cover device.

[0014] Furthermore, the bottom cover device includes a tank rotating roller rotatably mounted on a tank rotating frame, a motor frame and a tank rotating motor frame are placed on the ground, a propulsion motor is fixedly mounted on the motor frame, an eccentric wheel is fixedly mounted on the motor shaft of the propulsion motor, a connecting rod is rotatably mounted on the eccentric wheel, a cover pushing rod is rotatably mounted on the connecting rod, the cover pushing rod is slidably mounted with the tank rotating frame, a tank rotating motor is fixedly mounted on the tank rotating motor frame, the tank rotating roller is rotatably mounted with the tank rotating motor frame, a rotating gear is fixedly mounted on the motor shaft of the tank rotating motor, a tank rotating gear is fixedly mounted on the tank rotating roller, a tank rotating gear and a rotating gear are wrapped around a tank rotating belt, a bottom welding module is arranged at the bottom of the tank rotating frame, and a tank top cover is placed on the tank rotating frame.

[0037] like Figure 5-Figure 7 As shown, the tank device includes an outer cylinder 202 fixedly mounted on a bottom frame 201, a discharge plate 203 fixedly mounted on the outer cylinder 202, an inner frame 204 fixedly mounted on the outer cylinder 202, a cylinder pusher electric cylinder 205 fixedly mounted on the inner frame 204, a push rod 206 fixedly mounted on the top of the cylinder pusher electric cylinder 205, a rotating card 207 rotatably mounted on the push rod 206, a cylinder welding module 213 fixedly mounted on the inner frame 204, and a docking gear 214 rotatably mounted on the outer cylinder 202. 08, the docking gear 208 is meshed with the outer roller gear 116, three rollers 210 are fixedly installed on the outer cylinder 202, and roller gears 209 are fixedly installed on the rollers 210. The roller gears 209 are meshed with the docking gear 208, an inner roller 212 is rotatably installed on the outer cylinder 202, and an inner rotating gear 211 is fixedly installed on the inner roller 212.

[0038] The metal coil 104 enters between the rotating roller 210 and the inner roller 212.

The metal coil 104 is rolled into a cylinder along the inner wall of the outer cylinder 202 by the rotating roller 210 and the inner roller 212 to form a cylindrical metal coil 214. Then, the cylinder push cylinder 205 extends, driving the push rod 206 to push the cylindrical metal coil 214 to slide forward along the outer cylinder 202. The push rod 206 and the rotating clamp 207 will clamp the cylindrical metal coil 214 to prevent the cylindrical metal coil 214 from rotating during the forward movement. As the cylindrical metal coil 214 advances in the outer cylinder 202, the cylindrical metal coil 214 is welded by the cylinder welding module 213.

[0040] like Fig.11 As shown, a bent column 312 is slidably installed in the lower transmission column 311, and the bent column 312 is slidably installed with the upper transmission column 313.

[0041] like Figure 8-Figure 10As shown, the cover feeding mechanism includes a stand 320, the stand 320 is placed on the ground, a cylinder shell 322 is fixedly installed on the stand 320, a cover welding module 321 is fixedly installed on the stand 320, a tank cover 323 is placed in the cylinder shell 322, a sliding column 325 is fixedly installed on the stand 320, a blocking frame 324 is slidably installed on the sliding column 325, a return spring 326 is arranged between the blocking frame 324 and the stand 320, and an upper blocking block 3241 and a lower blocking block 3242 are arranged on the blocking frame 324.

[0042] After welding, the cylindrical metal coil 214 becomes a can 305 and falls onto the can drag rack 304. The reversing electric cylinder 302 contracts to drive the reversing rack 303 to rotate, thereby driving the can drag rack 304 to rotate along the transfer rack 301, so that the can 305 is turned over to the outside of the convex column 310 of the transmission belt 309. The transmission motor 307 rotates to drive the lower transmission column 311 and the driving gear 308 to rotate. The driving gear 308 rotates to drive the transmission belt 309 to transport the can 305. At the same time, the lower transmission column 311 rotates to drive the bending column 312 to rotate. The sliding of the bent column 312 in the lower transmission column 311 and the upper transmission column 313 drives the upper transmission column 313 to rotate, thereby driving the outer gear 314 to rotate, thereby driving the flat toothed belt 316 to rotate, thereby driving the toggle gear 317 and the toggle wheel 318 to rotate together. When the can barrel 305 moves on the transmission belt 309, the other side contacts the fixed side plate 306. The rotation of the toggle wheel 318 makes the can barrel 305 rotate at the same time as it moves with the transmission belt 309. When the can barrel 305 reaches the bottom of the barrel shell 322 The can barrel 305 will squeeze the blocking frame 324, causing the blocking frame 324 to slide inward along the sliding column 325, and the return spring 326 will be squeezed, so that the can cover 323 originally located on the lower blocking block 3242 will fall onto the can barrel 305, and at the same time, the upper blocking block 3241 will block the next can cover 323 to prevent it from falling. Then the can barrel 305 continues to move forward, driving the can cover 323 to move forward together. The can barrel 305 and the can cover 323 move forward and rotate at the same time. When passing through the cover welding module 321, the can cover 323 and the can barrel 305 are welded. 5 is welded. Since the tank cover 323 and the tank barrel 305 are rotating, a circle of weld seams of the tank cover 323 and the tank barrel 305 is welded. When the tank barrel 305 leaves the blocking frame 324, the return spring 326 starts to rebound, driving the blocking frame 324 to slide outward, so that the upper blocking block 3241 no longer blocks the next tank cover 323, and the tank cover 323 falls onto the lower blocking block 3242, preparing for the next welding. After the welding is completed, the transmission belt 309 will transport the tank barrel 305 to the transfer frame 301 and finally enter the bottom cover device.

A rotating gear 410 is fixedly installed on the motor shaft of the tank rotating motor 409, and a tank rotating gear 412 is fixedly installed on the tank rotating roller 411. A tank rotating belt 413 is wrapped around the tank rotating gear 412 and the rotating gear 410. A bottom welding module 402 is arranged at the bottom of the tank rotating frame 401, and a tank top cover 408 is placed on the tank rotating frame 401.

[0044] The can barrel 305 and the can cover 323 will fall onto the can rotating roller 411, and the eccentric wheel 405 will be driven to rotate by the propulsion motor 404, thereby driving the connecting rod 406 to rotate, thereby driving the cover pushing rod 407 to slide on the can rotating rack 401, and pushing the can top cover 408 onto the can barrel 305. At the same time, the can rotating motor 409 rotates to drive the rotating gear 410 to rotate, and the can rotating gear 412 and the can rotating roller 411 are driven to rotate through the can rotating belt 413, thereby driving the can barrel 305 to rotate, and the can top cover 408 is welded to the can barrel 305 through the bottom welding module 402, completing the welding of the entire food can.

[0045] The working principle of a large food can welding device disclosed in the present invention is as follows: a metal coil 104 is placed on a coil barrel 103, a roller motor 102 rotates, and a roller gear 106 and an outer roll roller 110 are driven to rotate through a motor gear 105, thereby driving an inner transfer gear 113 and an inner roll roller 111 to rotate through an outer transfer gear 112 and a transfer belt 114, thereby driving the metal coil 104 forward through the outer roll roller 110 and the inner roll roller 111, the metal coil 104 passes through a slope 115, and passes between an upper cutter 123 and a lower cutter 125, the inner roll roller 111 and the middle roll gear 107 drive the inner roller gear 109 and an inner rotating roller 126 to rotate through a long transmission belt 108, and the inner rotating roller 126 drives the inner roller transfer wheel 118 to rotate, thereby The belt 120 drives the outer roller drive wheel 119 and the outer roller 117 to rotate, and the metal coil 104 reaches the inner roller 126 and the outer roller 117 through the knife rope 124. The metal coil 104 is fed between the rotating roller 210 and the inner roller 212 through the rotation of the inner roller 126 and the outer roller 117. After a certain length of the metal coil 104 is fed in, the cutting electric cylinder 122 extends and drives the upper cutter 123 to descend along the cutting frame 121. The upper cutter 123 descends and drives the lower cutter 125 to rise along the cutting frame 121 through the knife rope 124. The metal coil 104 is cut to a specified length by the upper cutter 123 and the lower cutter 125. After the metal coil 104 enters between the rotating roller 210 and the inner roller 212, the rotation of the outer roller gear 116 drives the docking gear 208 to rotate. Thereby, the roller gear 209 and the roller 210 are driven to rotate, thereby driving the inner gear 211 and the inner roller 212 to rotate, and the metal coil 104 is rolled into a cylinder along the inner wall of the outer cylinder 202 by the roller 210 and the inner roller 212 to form a cylindrical metal coil 214. Then, the cylinder pusher electric cylinder 205 extends, driving the push rod 206 to push the cylindrical metal coil 214 to slide forward along the outer cylinder 202. The push rod 206 and the rotating card 207 will clamp the cylindrical metal coil 214 to prevent the cylindrical metal coil 214 from rotating during the forward movement. As the cylindrical metal coil 214 advances in the outer cylinder 202, the cylindrical metal coil 214 is welded by the cylinder welding module 213, and enters the discharge plate 203 after welding. After welding, the cylindrical metal coil 214 becomes a can The barrel 305 falls onto the barrel dragging frame 304, and the flip electric cylinder 302 contracts to drive the flip frame 303 to rotate, thereby driving the barrel dragging frame 304 to rotate along the transfer frame 301, so that the can barrel 305 is flipped to the outside of the convex column 310 of the transmission belt 309, and the transmission motor 307 rotates to drive the lower transmission column 311 and the driving gear 308 to rotate, and the driving gear 308 rotates to drive the transmission belt 309 to transport the can barrel 305. At the same time, the lower transmission column 311 rotates to drive the curved column 312 to rotate, and the sliding of the curved column 312 in the lower transmission column 311 and the upper transmission column 313 drives the upper transmission column 313 to rotate, thereby driving the outer gear 314 to rotate, thereby driving the flat toothed belt 316 to rotate, thereby driving the toggle gear 317 and the toggle wheel 318 to rotate together,When the can 305 moves on the transmission belt 309, the other side contacts the fixed side plate 306. The can 305 rotates while moving along with the transmission belt 309 through the rotation of the toggle wheel 318. When the can 305 reaches the bottom of the cylinder shell 322, the can 305 squeezes the blocking frame 324, causing the blocking frame 324 to slide inward along the sliding column 325. The return spring 326 is squeezed, causing the can cover 323 originally located on the lower blocking block 3242 to fall to the bottom of the cylinder shell 322. The upper stopper 3241 blocks the next can cover 323 to prevent it from falling. Then the can 305 continues to move forward, driving the can cover 323 to move forward together. The can 305 and the can cover 323 rotate while moving forward. When passing through the cover welding module 321, the can cover 323 and the can 305 are welded. Since the can cover 323 and the can 305 are rotating, a circle of weld seams of the can cover 323 and the can 305 are welded. When the can 305 leaves the can The blocking frame 324 is opened, and the return spring 326 begins to rebound, driving the blocking frame 324 to slide outward, so that the upper blocking block 3241 no longer blocks the next tank cover 323, and the tank cover 323 falls onto the lower blocking block 3242 to prepare for the next welding. After the welding is completed, the transmission belt 309 will transport the tank barrel 305 to the transfer frame 301, and the tank barrel 305 and the tank cover 323 will fall onto the tank rotating roller 411, and the eccentric wheel 405 will rotate by the propulsion motor 404. The can rotating gear 410 is driven by the can rotating belt 413 to rotate the can rotating gear 412 and the can rotating roller 411, thereby driving the can barrel 305 to rotate, and the can top cover 408 is welded to the can barrel 305 through the bottom welding module 402, thus completing the welding of the entire food can.
