Description

Technical Field

[0001] The invention relates to the technical field of tableware processing, in particular to an integrated aluminum foil lunch box forming device. Background Art

[0002] Aluminum foil lunch boxes, also known as aluminum disposable lunch boxes, are a widely used tableware. Their thickness is generally between 0.03mm and 0.20mm. They can be divided into two types: wrinkled and wrinkle-free, and also into two types: disposable and reusable. They are made of 3-series or 8-series aluminum ingot raw materials, cold-rolled or hot-rolled into aluminum foil mother rolls with uniform thickness, smooth surface, no pinholes, no dust particles, and no odor, and then formed by one-time fully automatic cold stamping through special equipment and molds. Aluminum foil lunch boxes have a wide range of applications, mainly including aviation food, home cooking, large chain cake shops, and pre-prepared dishes. Aluminum foil lunch boxes are available in square and round shapes.

[0003] In the process of forming aluminum foil lunch boxes, forming equipment is needed. The forming equipment drives the mold through hydraulic pressure. There are cutters around the mold. For example, for a round aluminum foil lunch box, there is a round cutter around the mold. The mold drives the cutter down to cut the aluminum foil from the flattened raw material roll to form a round piece of aluminum foil. The round aluminum foil is pressed into the mold below to form, and then pushed out of the mold by the ejection structure inside the mold.

[0004] However, the cutter around the mold only cuts by pressing down, and the cutter does not rotate. When the blade does not rotate, the friction and resistance between the aluminum foil and the blade increase, which can easily cause the surface of the aluminum foil to be torn or form burrs. Since the blade does not rotate, unevenness may occur during the cutting process, resulting in uneven incisions, causing burrs on the cut round aluminum foil, affecting the quality of the product. Dust is generated around the mold during cutting. A large amount of dust will affect the molding and needs to be cleaned regularly, which is very troublesome. After the formed lunch box is ejected, the staff needs to pick it up. The lunch box is close to the mold, which poses a safety hazard. Moreover, after cutting, aluminum foil scraps with holes in the middle are formed. The scraps still maintain their original width, which takes up a large space when recycled. The scraps need to be transferred and put into the crushing equipment, which consumes extra working time and increases the workload. Summary of the invention

[0045] The rotary drive mechanism 16 includes a fixed plate 161, a transmission column 162 and a toothed track 163. The fixed plate 161 is bolted to the surface of the lifting seat 9, the transmission column 162 is rotatably connected to the surface of the fixed plate 161, the toothed track 163 is bolted to the surface of the column 3, one end of the transmission column 162 is bolted with a transmission gear 164, the transmission gear 164 and the toothed track 163 are meshed with each other, and the other end of the transmission column 162 is connected to the rotating drum 10 through a bevel gear transmission.

[0046] The blowing mechanism 17 includes a fixed sleeve 171, a long cylinder 172 and a lifting plate 173. The fixed sleeve 171 is bolted to the upper surface of the column 3, the long cylinder 172 is bolted to the inner side of the fixed sleeve 171, and the lifting plate 173 is bolted to one side of the lifting seat 9. The top of the lifting plate 173 is bolted with a movable column 174, and the movable column 174 is slidably connected to the inlet of the long cylinder 172. The top of the movable column 174 is bolted with a first piston 175, and the first piston 175 is slidably connected to the inner wall of the long cylinder 172. The two sides of the top of the long cylinder 172 are respectively connected to an air inlet 176 and an air outlet 178, and the inner hinge of the air inlet 176 is connected to the inner wall of the long cylinder 172. There is a first one-way door 177, which is hinged by a spring hinge. The first one-way door 177 can only be opened in the direction of the interior of the long tube 172. A second one-way door 179 is hinged inside the air outlet 178. The second one-way door 179 is hinged by a spring hinge. The first one-way door 177 can only be opened in the direction away from the inside of the long tube 172. The blowing mechanism 17 also includes a transverse tube 1711 bolted to one side of the top of the lower mold base 5. The top of the air outlet 178 is connected to an air supply pipe 1710, and the end of the air supply pipe 1710 away from the air outlet 178 is connected to the transverse tube 1711. The surface of the transverse tube 1711 is connected to a plurality of air nozzles 1712. The number of the air nozzles 1712 is several and they are equidistantly arranged. When the lifting seat 9 descends, it can drive the lifting plate 173 to descend together. Then the lifting plate 173 drives the movable column 174 and the first piston 175 to descend together. The descent of the first piston 175 forces the space volume above the interior of the long cylinder 172 to increase, causing the air pressure above the interior of the long cylinder 172 to decrease. Under the effect of the internal and external air pressure difference, the external air pushes open the first one-way door 177 and enters the interior of the long cylinder 172, while the second one-way door 179 is closed and cannot be opened to the inside.

The first one-way door 177 will not open to the outside, so the gas will not be discharged from the air inlet 176. After that, the gas passes through the air pipe 1710 and the cross pipe 1711, and is discharged from the air nozzle 1712. The direction of the gas flow passes through the top of the lower mold 6 and blows toward the lower material table 4.

[0047] The cutting mechanism 19 includes a shell 191, a first rotating column 192 and a second rotating column 193. The shell 191 is bolted to the surface of the column 3. The first rotating column 192 and the second rotating column 193 are both rotatably connected to the shell 191, and the first rotating column 192 and the second rotating column 193 are connected by gear transmission.

The number of the first cutter 195 and the second cutter 196 are both several and staggered. The cutting mechanism 19 also includes a driving motor 194, a first pinch roller 197 and a second pinch roller 198. The first pinch roller 197 and the second pinch roller 198 are both rotatably connected to the column 3.

The first rotating column 192 is connected to the first pinch roller 197 are connected by belt transmission, and the first pinch roller 197 and the second pinch roller 198 are connected by gear transmission. The surface of the column 3 and the two sides of the lower mold base 5 are rotatably connected with the first auxiliary roller 21 and the second auxiliary roller 22 respectively. Turn on the driving motor 194, and its output shaft can drive the first rotating column 192 to rotate through gears. The first rotating column 192 drives the second rotating column 193 to rotate through gears. The rotation directions of the first rotating column 192 and the second rotating column 193 are opposite. Then the first rotating column 192 drives the first pinch roller 197 to rotate through a belt, and the first pinch roller 197 drives the second pinch roller 198 to rotate through gears. The rotation direction of the first pinch roller 197 is the same as the rotation direction of the first rotating column 192, while the rotation direction of the first pinch roller 197 is opposite to the rotation direction of the second pinch roller 198.

[0048] When working, the equipment is equipped with a bracket for placing the aluminum foil roll (not shown in the figure), the aluminum foil is placed on the bracket, and the aluminum foil is unrolled and pulled between the first pinch roller 197 and the second pinch roller 198 on both sides. At the same time, the aluminum foil passes through the first auxiliary roller 21 and the second auxiliary roller 22, and the drive motor 194 is turned on to drive the first rotating column 192 and the second rotating column 193 to rotate, and the first pinch roller 197 and the second pinch roller 198 rotate synchronously.

At this time, the ring The annular knife 14 rotates, and the annular knife 14 is at a lower position than the upper mold 12. The annular knife 14 contacts the aluminum foil first, and cuts a circular piece from the surface of the aluminum foil during the rotation. The rotating annular knife 14 can cut the aluminum foil more effectively, because the kinetic energy generated by the rotation helps the blade to penetrate the material more smoothly, and can reduce the friction and resistance during the cutting process, thereby reducing the risk of the aluminum foil being torn or generating burrs, while ensuring uniform wear of various parts of the blade, extending the service life of the blade, and making the edge of the circular aluminum foil cut smoother; during the descent of the lifting seat 9, the annular knife 14, etc., gas enters the interior of the long cylinder 172.

A slider 185 is welded on one side of the surface of the push rod 182, and the slider 185 is slidably connected to the inner wall of the vertical groove 184. The slider 185 can slide up and down along the inner wall of the vertical groove 184, so that the push rod 182 can only move in the vertical direction, preventing the push rod 182 from rotating and causing the first spring 183 to twist. The ejection mechanism 18 also includes a sliding sleeve 186, a receiving plate 187 and a movable rod 188. The sliding sleeve 186 is bolted to one side of the lower mold base 5.

The bottom end of the vertical rod 1810 is bolted to the cross bar 189. A circular plate 1812 is bolted to the surface of the vertical rod 1810 and is located on the inner side of the lower mold 6. The bottom of the circular plate 1812 is fixed. There is a second spring 1811, the first spring 183 and the second spring 1811 are both compression springs, the other end of the second spring 1811 is fixed to the inner wall of the lower die seat 5, when the receiving plate 187 is not subjected to force, the upward reaction force of the second spring 1811 causes the circular plate 1812, the vertical rod 1810 and the ejector plate 1814 to be subjected to an upward force, so that the ejector plate 1814 is at a high position inside the lower die 6, and the top of the ejector plate 1814 is slightly higher than the lower die 6, and when the lifting seat 9 descends and the annular knife 14 cuts the aluminum foil, the sleeve 181 and the ejector rod 182 follow the decline, and then the annular knife 14 enters the annular groove 7, and the upper die 12 follows the decline, and is about to cut the aluminum foil on the aluminum foil. The aluminum foil contacts with the upper mold 6, and at the same time, the ejector rod 182 contacts with the receiving plate 187 first. The elastic modulus of the first spring 183 is greater than the elastic modulus of the second spring 1811. The ejector rod 182 is subjected to the force from the first spring 183 to push the receiving plate 187 downward, so that the receiving plate 187 is subjected to a downward force, and drives the cross bar 189, the vertical rod 1810, the ejector plate 1814 and the circular plate 1812 to descend together, and the ejector plate 1814 is temporarily retracted into the vertical cylinder 1813 and flush with the bottom of the inner wall of the lower mold 6, and the upper mold 12 presses the cut circular aluminum foil into the lower mold 6 for molding; during the downward pressing process, the first pinch roller 197 and the second pinch roller 198 are temporarily stopped.

[0050] After the molding is completed, the output shaft of the hydraulic cylinder 8 contracts to drive the lifting seat 9 and the lifting plate 173 to rise, which causes the ejector rod 182 to continue to rise. When the receiving plate 187 lacks external force, the vertical rod 1810, the circular plate 1812 and the ejector plate 1814 rise, and the formed lunch box is ejected to the outside of the lower mold 6. The lifting plate 173 drives the movable column 174 and the first piston 175 to rise, so that the gas is ejected from the gas nozzle 1712. Since the aluminum foil lunch box is light in weight, it is easy to be blown away, and then the aluminum foil lunch box falls on The surface of the unloading table 4 does not require the staff to take the material from near the mold by hand, which is safer. At the same time, the aluminum foil lunch box is lightweight and will not be broken when it falls. At the same time, the first clamping roller 197 and the second clamping roller 198 continue to operate to transport the aluminum foil into the shell 191. At this time, circular holes appear on the surface of the aluminum foil scraps, and the first rotating column 192 and the second rotating column 193 can respectively drive the first cutter 195 and the second cutter 196 to rotate to cut the scraps into pieces, without the need for staff to transfer the scraps to the cutting equipment.

[0051] The adsorption mechanism 23 includes an annular tube 231, a short tube 232, a first pipeline 233, a box body 234 and a box body 237. The annular tube 231 is arranged on the inner side of the lower mold base 5, the short tube 232 is connected to the top of the annular tube 231, and the top of the short tube 232 passes through the inner side of the annular groove 7, one end of the first pipeline 233 is connected to the annular tube 231, the box body 234 is bolted to the top of the base 1, the box body 237 is bolted to the surface of the column 3, the end of the first pipeline 233 away from the annular tube 231 is connected to the box body 234, a blocking net 235 is bolted to the top of the box body 234, the top of the box body 234 is connected to a conveying pipe 236, the bottom of the box body 237 is connected to a lower inlet 2315, the top of the box body 237 The lower inlet 2315 and the upper outlet 2317 are connected to each other with a first one-way cover 2316 and a second one-way cover 2318 respectively hingedly connected inside the box body 237. The first one-way cover 2316 can only be opened toward the inside of the box body 237, while the second one-way cover 2318 can only be opened toward the outside of the box body 237. The adsorption mechanism 23 also includes a turntable 238 bolted to one end of the first rotating column 192, and a driving rod 239 is rotatably connected to the surface of the turntable 238. A ring 2312 is penetrated on the surface of the box body 237, and a piston rod 2311 is slidably connected to the inner wall of the ring 2312. One end of the piston rod 2311 is bolted to a connecting piece 2310, and the end of the driving rod 239 away from the turntable 238 is hinged to the connecting piece 2310. , the end of the piston rod 2311 away from the connecting piece 2310 is bolted with the second piston 2313, and the second piston 2313 is slidably connected to the inner wall of the box body 237. During the rotation of the first rotating column 192, it can drive the turntable 238 to rotate, and the turntable 238 drives one end of the driving rod 239 to make a circular motion. The other end of the driving rod 239 drives the piston rod 2311 to reciprocate through the connecting piece 2310. The piston rod 2311 drives the second piston 2313 to reciprocate inside the box body 237. When the second piston 2313 moves toward the direction close to the ring 2312, the volume of the box body 237 near the lower inlet 2315 increases, the internal pressure decreases, and the external air passes through the delivery pipe 236 and the lower inlet 2315 and The first one-way cover 2316 is pushed open to enter the box body 237, and the second one-way cover 2318 will not be opened to the inside of the box body 237. When the second piston 2313 moves in the direction away from the ring 2312, the volume of the box body 237 near the lower inlet 2315 is reduced, the gas is squeezed, and the second one-way cover 2318 is pushed open and discharged from the upper outlet 2317. At the same time, the first one-way cover 2316 will not be pushed open. At this time, these structures form a principle similar to that of a reciprocating pump, and the air in the box body 234 is extracted, which forms a negative pressure in the box body 234 and generates a negative pressure at the inlet of the short tube 232. The dust generated by the annular knife 14 cutting the aluminum foil and the surrounding air pass through the short tube 232, the annular tube 231, and the first pipe 233 and then enter the box body 234.And it is intercepted by the blocking net 235, so as to realize the cleaning of the cutting part of the mold and prevent a large amount of dust from accumulating near the mold. In actual use, the surface of the box 234 can be designed with a door that can be opened to clean the dust inside. One side of the surface of the box 234 is also connected with a second pipe 2319. The surface of the second pipe 2319 is connected with a plurality of inlet pipes 2314, and the end of the inlet pipe 2314 away from the second pipe 2319 passes through the interior of the shell 191. In the process of generating negative pressure inside the box 234, suction is also generated at the inlet pipe 2314. The dust generated by cutting the scraps can also enter the interior of the box 234 through the inlet pipe 2314 and the second pipe 2319, so as to realize the adsorption of dust at the cutting part of the scraps. The cut scraps become strips, and the conveyor belt 20 is turned on (the conveyor belt 20 is a prior art, and its specific structure and working principle are not described in detail) to transport the cut scraps to the outside of the equipment for cleaning.
