Description

Technical Field

[0001] This invention relates to the technical field of metal cap production for packaging cans, specifically a three-mold cap production line. Background Technology

[0002] In the production of metal caps for packaging cans, the material must first be punched and blanked before subsequent processing. Existing production lines generally unfold the metal sheet and punch it in a straight single row before processing. To improve efficiency, the width of the metal sheet is increased to cover the width of three sets of metal caps, resulting in a three-mold cap production line. After the metal cap is shaped at the front end of the three-mold cap production line, there are two requirements for sealing the cap: one is to insert a rubber strip into the inner wall of the cap, and the other is to inject glue into the inner cavity of the cap. Current technology uses two independent production lines. Since the processes for processing the cap are the same, the independent setup of the two production lines results in high equipment costs. Therefore, there is an urgent need to develop a three-mold cap production line that can simultaneously accommodate rubber strip insertion and glue injection, thereby reducing equipment costs. Summary of the Invention

[0003] To address the aforementioned issues, this invention provides a three-mold cap production line that allows the post-processing line for inserting rubber strips and injecting adhesive to be simultaneously adapted to the pre-processing line for three-mold caps, thereby reducing equipment and site costs.

[0004] A three-mold cap production line, characterized in that it comprises: The front-end module of the three-mold cover production line includes a strip unwinding mechanism, a strip tensioning mechanism, a first punching module, a second punching module, a middle sheet conveying mechanism, two side sheet conveying mechanisms, a three-mold processing and forming mechanism, and a three-mold linear conveying module. A rubber strip insertion module includes a linear feeding assembly, a rubber strip insertion machine, and a finished product collection cap. The linear feeding assembly includes a linear switching feeding mechanism and a linear receiving feeding mechanism. And the glue injection module, which includes a three-mold conveying module, a three-mold glue injection machine, an oven, and a receiving mechanism; The output end of the three-mode linear conveyor module is connected to the linear input line of the three-mode conveyor module. The linear input line of the three-mode conveyor module is arranged lower than the three-mode linear conveyor module. The linear switching feeding mechanism includes a horizontal state and a vertical state. In the vertical state, the linear switching feeding mechanism is perpendicular to the three-mode linear conveyor module and connected to the output end of the three-mode linear conveyor module. In the horizontal state, the linear switching feeding mechanism is parallel to the linear input line and located beside the linear input line, and is not in operation. When the front-end process module of the three-mold cap production line is connected to the rubber strip plugging module, the linear switching feeding mechanism is in a vertical state. The linear switching feeding mechanism is stacked on the linear input line. The three-mold linear conveying module synchronously conveys the three sets of caps to the conveyor belt of the linear material changing mechanism and to the linear receiving feeding mechanism until the rubber strip plugging machine completes the processing and sends them to the corresponding finished cap collector. When the front-end process module of the three-mold cap production line is connected to the glue injection module, the linear switching feeding mechanism is in a horizontal state. The three-mold linear conveying module synchronously conveys the three sets of caps to the linear input line of the three-mold conveying module, and the caps are finally collected by the receiving mechanism after passing through the three-mold glue injection machine and the drying oven.

[0005] Its further features are: The linear feeding assembly further includes a first switching conveyor line and a second switching conveyor line. The first switching conveyor line and the second switching conveyor line are both perpendicular to the linear receiving and feeding mechanism and are respectively arranged on both sides of the end of the linear receiving and feeding mechanism. The end of the linear receiving and feeding mechanism is provided with a diversion baffle. When the diversion baffle is not in use, the cover of the linear receiving and feeding mechanism is conveyed to the input end of the second switching conveyor line. When the diversion baffle is open and in use, the cover of the linear receiving and feeding mechanism is guided to the input end of the first switching conveyor line through the diversion baffle. A first push cylinder group is set on one side of the end of the first switching conveyor line, and a first rubber strip insertion machine is set on the other side of the end of the first switching conveyor line. The first rubber strip insertion machine is equipped with rubber strip insertion stations corresponding to the number of push cylinders of the first push cylinder group. After all the rubber strip insertion stations have completed the rubber strip insertion of the cap, the cap is conveyed in a straight line to the finished cap collector for collection. A second push cylinder group is set on one side of the end of the second switching conveyor line, and a second rubber strip insertion machine is set on the other side of the end of the second switching conveyor line. The second rubber strip insertion machine is equipped with rubber strip insertion stations corresponding to the number of push cylinders of the second push cylinder group. After all the rubber strip insertion stations have completed the rubber strip insertion of the cap, the cap is conveyed in a straight line to the finished cap collector for collection. The output ends of the first and second switching conveyor lines are respectively equipped with cap collectors for excess caps. When the production line cap production speed is normal, but there is a rubber strip material switching station with a blocked rubber strip, the excess caps will be buffered in the cap collector to ensure the normal operation of the production line. The three-mold conveyor module includes a linear input line and a circular conveyor belt. The linear input line is connected to the input end of the circular conveyor belt. The circular conveyor belt synchronously inputs three sets of covers into the three-mold glue injection machine. The output end of the three-mold glue injection machine is connected to the first linear input end of a U-shaped conveyor belt. The second linear output end of the U-shaped conveyor belt corresponds to the input end of the oven. A synchronous push rod synchronously pushes several covers located at the input end of the oven into the oven. The output end of the oven is equipped with a buffer wide material belt. The output end of the buffer wide material belt is equipped with a single-cover conveyor belt. The conveying direction of the cover conveyor belt is perpendicular to the buffer wide material belt. The output end of the single-cover conveyor belt corresponds to the buffer long material belt. The output end of the buffer long material belt is equipped with a receiving mechanism. The oven is a tunnel-type oven, and the material width of the oven is covered with at least 4 lids, which ensures that more lids can be accommodated in the tunnel-type oven for baking at the same time, resulting in high drying efficiency of the colloid.

[0006] By adopting the solution of this invention and coordinating with capacity calculation, the switching between the horizontal and vertical states of the linear switching feeding mechanism can be completed, which is quick and convenient. This allows the downstream production line for rubber strip insertion and glue injection to be adapted to the upstream production line for three-mold caps, reducing equipment and site costs.

The linear input line 131 of the three-mode conveyor module 130 is arranged below the three-mode linear conveyor module 80. The linear switching feeding mechanism 91 includes a horizontal state and a vertical state. In the vertical state, the linear switching feeding mechanism 91 is perpendicular to the three-mode linear conveyor module 80 and connected to the output end of the three-mode linear conveyor module 80. In the horizontal state, the linear switching feeding mechanism 91 is parallel to the linear input line 131 and is located beside the linear input line 131 and is not in operation. When the front-end module 100 of the three-mold cap production line connects to the rubber strip plugging module 200, the linear switching feeding mechanism 91 is in a vertical state. The linear switching feeding mechanism 91 is stacked on the linear input line 131. The three-mold linear conveying module 80 synchronously conveys the three sets of caps to the conveyor belt of the linear material changing mechanism 91 and then to the linear receiving feeding mechanism 92, until the rubber strip plugging machine 110 completes the processing and sends them to the corresponding finished cap collector 120. When the front-end process module 100 of the three-mold cap production line connects to the glue injection module 300, the linear switching feeding mechanism 91 is in a horizontal state. The three-mold linear conveying module 80 synchronously conveys the three sets of caps to the linear input line 131 of the three-mold conveying module 130, and the caps pass through the three-mold glue injection machine 140 and the oven 150 before finally being collected by the receiving mechanism 160.

[0009] In specific implementation, the linear feeding assembly 90 also includes a first switching conveyor line 93 and a second switching conveyor line 94. The first switching conveyor line 93 and the second switching conveyor line 94 are both perpendicular to the linear receiving and feeding mechanism 92 and are respectively arranged on both sides of the end of the linear receiving and feeding mechanism 92. The end of the linear receiving and feeding mechanism 92 is provided with a diversion baffle 95. When the diversion baffle 95 is not in use, the cover of the linear receiving and feeding mechanism 92 is conveyed to the input end of the second switching conveyor line 94. When the diversion baffle 95 is open and in use, the cover of the linear receiving and feeding mechanism 92 is guided to the input end of the first switching conveyor line 93 through the diversion baffle 95.

After all the rubber strip inserting stations have completed the rubber strip insertion of the cap, the cap is conveyed in a straight line to the finished cap collector 120 for collection. A second push cylinder group 180 is provided on one side of the end of the second switching conveyor line 94, and a second rubber strip inserting machine 112 is provided on the other side of the end of the second switching conveyor line 94.

The output ends of the first switching conveyor line 93 and the second switching conveyor line 94 are respectively equipped with a cover collector 190 for excess covers. When the production line cover production speed is normal, but there is a rubber strip material switching station with a blocked rubber strip, the excess covers will be buffered in the cover collector 190 to ensure the normal operation of the production line. The three-mold conveyor module 130 includes a linear input line 131 and a circular conveyor belt 132. The linear input line 131 is connected to the input end of the circular conveyor belt 132.

The output end of the three-mold glue injection machine 140 is connected to the first linear input end of the U-shaped conveyor belt 210. The second linear output end of the U-shaped conveyor belt 210 corresponds to the input end of the oven 150. A synchronous push rod synchronously pushes several lids located at the input end of the oven into the oven 150. The output end of the oven 150 is equipped with a buffer wide material belt 220. The output end of the buffer wide material belt 220 is equipped with a single-lid conveyor belt 230. The conveying direction of the lid conveyor belt 230 is perpendicular to the buffer wide material belt 220. The output end of the single-lid conveyor belt 230 corresponds to the buffer long material belt 240. The output end of the buffer long material belt 240 is equipped with a receiving mechanism 160. The buffer long material belt 240 is used for natural cooling of the lids. Oven 150 is a tunnel oven, and the material width of oven 150 is covered with at least 4 lids, which ensures that more lids can be accommodated in the tunnel oven for baking at the same time, resulting in high drying efficiency of the colloid.

[0010] In conjunction with capacity calculation, the switching between the horizontal and vertical states of the linear switching feeding mechanism can be completed for the cap stuffing rubber strips and glue injection. The switching is quick and convenient, which allows the downstream production line for stuffing rubber strips and injecting glue to be adapted to the upstream processing production line for three-mold caps, reducing equipment and site costs.
