Description

Technical Field

[0001] The present invention relates to the technical field of bottle cap assembly, and in particular to a device and method for automatically assembling inner and outer covers of a sauce bottle cap. Background Art

[0002] With the continuous development of automation technology, the market demand for automatic assembly devices for inner and outer caps of bottle caps continues to grow, especially in the food and cosmetics industries, which have higher requirements for efficient and hygienic production methods. When assembling sauce bottle caps, automatic assembly devices can be used to assemble the outer cap, inner cap and soft aluminum film of the sauce bottle caps.

[0003] Among them, the soft aluminum film is usually located under the inner cover, which plays a role of further sealing and preservation. Before the first use, the soft aluminum film can effectively prevent the leakage and deterioration of the material in the container. When the user needs to use it, the soft aluminum film needs to be torn off first. The soft aluminum film has good barrier properties and can prevent air, moisture and bacteria from entering the container.

[0004] When installing soft aluminum film in bottle caps, multiple rolls of aluminum film are required. In the process of replacing the aluminum film rolls, it is often necessary to pause the device first and continue working after the aluminum film is replaced. In the process of replacing the aluminum film rolls, pausing the device often leads to a decrease in production efficiency. Especially in large-scale production, frequent shutdowns to replace aluminum film rolls will significantly affect the continuity and production capacity of the production line. Moreover, when the equipment is stopped to replace the aluminum film rolls, restarting the equipment will also cause changes in production parameters (such as temperature, pressure, speed, etc.), affecting product quality, and ultimately reducing the product qualification rate, increasing the scrap rate and rework rate, affecting the sealing and preservation effect of the product, especially in the food industry, which can easily lead to product deterioration or contamination.

[0056] A method for automatically assembling the inner and outer covers of a sauce bottle cap, using the above-mentioned automatic assembly device for the inner and outer covers of a sauce bottle cap, comprises the following steps:

[0057] The first step is injection molding of the outer cover, which is performed using a horizontal injection molding machine to form the outer cover;

[0058] The second step is cap sorting. The outer caps after injection molding are transported to three vibration plates through the conveyor track for cap sorting.

[0059] The fourth step is feeding, which is transferred from the vibrating plate to the feeding track. There are also 3 feeding tracks. A mobile feeding channel is set in the middle of the feeding track. Each feeding track is provided with a sensor. When the outer covers on the feeding track reach the sensor position, the number of outer covers on the feeding track reaches the predetermined number, and the mobile feeding channel moves to the corresponding feeding track, so that the outer covers that have reached the predetermined number move forward through the mobile feeding channel until they move to the closing mechanism.

[0060] The fifth step is to close the cover. A plurality of fixed claws are provided on the outer periphery of the turntable to fix the outer cover. A closing block is also provided on the outer periphery of the turntable. The outer cover passes through the closing block under the drive of the turntable to close the outer cover. The closed outer cover is then transported to the inner and outer cover assembly mechanism.

[0061] The sixth step is assembly. In the inner and outer cover assembly mechanism, the soft cover and the soft cover bracket are first assembled together, and the two assembled together are taken out and moved upward. The pressure rod is pressed down again to press the soft cover bracket and the soft cover into the closed outer cover to complete the assembly of the inner and outer covers. The assembled covers are then transported to the soft aluminum film assembly mechanism.

[0062] The seventh step is loading. The bottle caps are fed into a group of feeding troughs side by side through the feeding equipment, that is, three bottle caps are fed into the corresponding feeding troughs at the same time. Then the third motor is started to drive the feeding tray to rotate intermittently in the installation tray. Each time it rotates, three bottle caps will enter the feeding troughs at the corresponding positions. At the same time, each time it stops, three bottle caps will enter the lower part of the positioning frame. The three bottle caps in this area correspond to the three punching holes on the positioning frame respectively, and can be punched and installed.

[0063] The eighth step is stamping. Start the fourth electric cylinder to drive the carrier frame to rise, align the punching rod with the punching hole, then retract the fourth electric cylinder to allow the punching rod to enter the punching hole. Then start the fifth electric cylinder to push the connecting frame to drive the punching rod downward to punch the aluminum film into the bottle cap to ensure that the aluminum film and the bottle cap are tightly combined. After the stamping is completed, the carrier frame is pushed up by the fourth electric cylinder, and the fifth electric cylinder is retracted at the same time. At this time, the punching rod is separated from the punching hole, completing a stamping cycle.

[0064] The ninth step is to load the aluminum film. The first motor is started synchronously to drive the fixed frame and the mounting frame to rotate, so that the aluminum film on the corresponding aluminum film roll is removed. At the same time, the second motor is started to drive one of the feed rollers to rotate, thereby driving the aluminum film to move with the cooperation of the other feed roller.

[0065] The tenth step is to replace the aluminum film. Without stopping the Azhuang aluminum film, the second and third electric cylinders at ABCD are used to connect the old and new sections of aluminum film.

[0066] The eleventh step is unloading. After the aluminum film is installed, the bottle caps will fall into the discharge rack as the feed tray rotates and passes through the discharge chute. By setting a discharge device in the discharge rack, the bottle caps with the aluminum film installed can be sent to the next link to complete the bottle cap assembly.

[0067] The working principle and beneficial effects of the present invention are:

[0068] 1. In the present invention, through the cooperation of the arc-shaped pressure strip and the arc-shaped groove, the edge of the arc-shaped groove and the welding frame are smoothly transitioned, thereby preventing the aluminum film from being bent, ensuring the flatness of the aluminum film and the welding quality, and making the docking and welding of the aluminum film more efficient and accurate.

[0069] 2. In the present invention, by cooperating with the second electric cylinder and the third electric cylinder at four points ABCD, the aluminum film can be quickly replaced without stopping the installation process of the aluminum film and the bottle cap, while ensuring the neatness and tightness of the docking of the two sections of aluminum film, thereby ensuring the stability of the production process and the consistency of product quality.

[0070] 3. In the present invention, the continuity of the bottle cap assembly is improved through the cooperation of the continuous stamping component and the feeding component. The crimping component is set in four areas, and the second electric cylinder and the third electric cylinder in the four areas cooperate with each other. The aluminum film can be docked without stopping the installation, and the accuracy of the docking is improved. The setting of the unwinding component facilitates the replacement of the used aluminum film, and at the same time, space is reserved for docking the old and new aluminum films, which further reduces the impact on the installation during the replacement of the aluminum film.

[0084] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0085] Example 1, as Figures 1 to 11As shown, this embodiment proposes an automatic assembly device for the inner and outer covers of sauce bottle caps, including an equipment frame 1, a discharge frame 2 is provided on one side of the equipment frame 1, including a punching frame 3, a discharge assembly, a crimping assembly, a continuous punching assembly and a feeding assembly, the punching frame 3 is fixedly installed inside the equipment frame 1, the discharge assembly is installed on the discharge frame 2, and is used to place the soft aluminum film roll, the discharge assembly includes a fixed frame 4, a mounting frame 5, a first motor 6 and a guide conveying part, the discharge frame 2 is symmetrically and rotatably installed with two fixed frames 4 on one side away from the equipment frame 1, and the ends of the two fixed frames 4 are detachably installed with mounting frames 5, two first motors 6 are fixedly installed on the discharge frame 2, and the output ends of the two first motors 6 are respectively fixedly connected to the two fixed frames 4, and the guide conveying part is installed on the discharge frame 2 for guiding the soft aluminum film.

[0086] The bottle cap consists of an outer cap, an inner cap and a soft aluminum film. After the inner and outer caps are assembled, the assembly of the cap and the aluminum film can begin.

[0087] Specifically, before assembling the cap and the aluminum film, the aluminum film roll to be used is installed first, and the aluminum film roll is placed on the fixing frame 4. The two fixing frames 4 are both equipped with aluminum film rolls, and the sleeves of the aluminum film rolls are fixed on the fixing frames 4. Then the mounting frame 5 is installed on the fixing frame 4 in the form of a threaded connection, so as to fix the axial position of the aluminum film roll and facilitate disassembly and assembly. The aluminum film end on one of the aluminum film rolls is passed through the crimping assembly and the guide conveying part. At this time, the guide conveying part is started to drive the aluminum film roll to move intermittently, and the first motor 6 is started at the same time. The first motor 6 drives the fixing frame 4 and the mounting frame 5 to rotate, so that the aluminum film on the corresponding aluminum film roll is removed, which is convenient for installation operation. At the same time, the bottle cap is continuously transported to the inside of the feeding assembly. Through the setting of the feeding assembly, the bottle cap is continuously sent to the inside of the continuous stamping assembly. At this time, the continuous stamping assembly can be started to stamp the aluminum film, and the punched aluminum film is installed in the bottle cap. Then, through the setting of the feeding assembly, the bottle cap with the installed aluminum film is sent out.

[0088] The above, such as Figures 2 to 4As shown, the guide conveying part includes a guide roller 7, an arc-shaped guide frame 8 and a pressing frame 9. Two guide rollers 7 are rotatably and symmetrically installed on the unloading frame 2. The arc-shaped guide frame 8 is fixedly installed on the unloading frame 2. The tail of the arc-shaped guide frame 8 is fixedly installed inside the equipment frame 1, wherein the arc-shaped guide frame includes a straight section and an arc-shaped section. The straight section is located inside the equipment frame 1, and the arc-shaped section is located between the equipment frame 1 and the unloading frame 2, and the opening direction of the arc-shaped section is upward. The pressing frame 9 is rotatably installed on the arc-shaped section, and the free end of the pressing frame 9 abuts against the upper side of the arc-shaped section. It also includes a conveying frame 10, a feeding roller 11 and a second motor 12. The conveying frame 10 is fixedly installed at the discharge end of the equipment frame 1, and two feeding rollers 11 are symmetrically and rotatably installed on the conveying frame 10. A second motor 12 is fixedly installed on the conveying frame 10, and the output end of the second motor 12 is fixedly connected to the feeding roller 11.

[0089] Specifically, after the end of the aluminum film on one of the aluminum film rolls passes through the crimping assembly, the end of the aluminum film passes through the two guide rollers 7, then bypasses the lower part of the pressing frame 9, and can pass into the straight section of the arc-shaped guide frame 8 until it enters between the two feed rollers 11. The two feed rollers 11 clamp the aluminum film. When it is necessary to drive the aluminum film to move, start the second motor 12. The second motor 12 drives one of the feed rollers 11 to rotate, thereby driving the aluminum film to move with the cooperation of the other feed roller 11. During the movement, the pressing frame 9 and the aluminum film maintain relative sliding. Under the action of the gravity of the pressing frame 9, the aluminum film slides and cooperates with the arc section of the arc-shaped guide frame 8, so that work can continue during the process of replacing the aluminum film roll without stopping, thereby improving work efficiency.

[0090] like Figures 5 to 8 As shown, a crimping assembly is installed on the unloading frame 2 for replacing the soft aluminum film roll during operation and sending it to the working position. The crimping assembly includes an ultrasonic welding machine 13, which is fixedly mounted on the unloading frame 2. The crimping assembly also includes a first electric cylinder 14, a welding frame 15, a welding plate 16, a welding plate 17, an adjustment portion and a positioning portion. The first electric cylinder 14 is fixedly mounted on the unloading frame 2. The first electric cylinder 14 is located at the lower part of the ultrasonic welding machine 13. The output end of the first electric cylinder 14 is connected to the lower part of the ultrasonic welding machine 13. Both welding frames 15 are fixedly installed, and the two welding frames 15 are symmetrically arranged. A welding plate 16 is fixedly installed on the welding frame 15 located at the bottom of the ultrasonic welding machine 13, and the welding plate 16 is fixedly connected to the working end of the ultrasonic welding machine 13. A welding plate 17 is fixedly installed on the welding frame 15 located at the output end of the first electric cylinder 14. Two adjustment parts are symmetrically installed on the welding plate 16 and the welding plate 17. A positioning part is installed at both ends of each adjustment part for fixing the soft aluminum film, and the adjustment part is used to adjust the position of the positioning part.

[0091] Specifically, when the aluminum film on the upper fixing frame 4 enters the working position, the end of the aluminum film roll on the lower fixing frame 4 is placed on the welding frame 15 on the first electric cylinder 14 until the end of the aluminum film roll is located in the area of ​​the welding plate 17. At this time, the position of the positioning part is adjusted by the adjusting part, and then the aluminum film is fixed in the position on the welding plate 17 by the positioning part. When the aluminum film roll entering the working position is about to be used up, the tail end of the aluminum film enters the area of ​​the welding plate 16. At this time, the aluminum film is fixed by the setting of the adjusting part and the positioning part on the welding frame 15 at the bottom of the ultrasonic welding machine 13, and then the first electric cylinder 14 is started. The first electric cylinder 14 pushes the corresponding welding frame 15 to move until the new and old sections of aluminum film are docked, and the two sections of aluminum film are pressed by the welding plate 16 and the welding plate 17. At this time, the ultrasonic welding machine 13 is started to dock the two sections of aluminum film together, and then the first electric cylinder 14 can be retracted.

[0092] The above, such as Figure 8 As shown, the positioning part includes a positioning frame 18 and a second electric cylinder 19. Two positioning frames 18 are symmetrically and slidingly installed on the welding plate 16 and the welding plate 17. Two second electric cylinders 19 are symmetrically and fixedly installed on the two welding frames 15. The output end of the second electric cylinder 19 is fixedly connected to the positioning frame 18.

[0093] Specifically, when the position of the arc-shaped beading 21 needs to be adjusted, the second motor 12 is started, and the second motor 12 drives the adjustment frame 18 to move, thereby adjusting the position of the arc-shaped beading 21, thereby fixing and adjusting the position of the aluminum film.

[0094] The above, such as Figure 8 As shown, the positioning part includes an arc groove 20, an arc pressure strip 21 and a third electric cylinder 22. Two arc grooves 20 are symmetrically opened on the two welding frames 15. The edges of the arc groove 20 smoothly transition with the welding frames 15. The two ends of each adjustment frame 18 are symmetrically and slidably installed with an arc pressure strip 21. The two ends of each adjustment frame 18 are symmetrically and fixedly installed with a third electric cylinder 22. The output end of the third electric cylinder 22 is fixedly connected to the arc pressure strip 21.

[0095] Specifically, when it is necessary to fix the position of the aluminum film on the welding frame 15, the third electric cylinder 22 is started with the cooperation of the second electric cylinder 19, and the third electric cylinder 22 pushes the arc pressure strip 21 out until the aluminum film is between the welding frame 15 and the arc pressure strip 21, and then the second electric cylinder 19 is retracted. The position of the aluminum film on the welding frame 15 can be fixed by the cooperation of the arc pressure strip 21 and the arc groove 20, and the setting of the arc groove 20 can prevent the aluminum film from being bent, thereby ensuring the flatness and welding quality of the aluminum film, making the docking and welding of the aluminum film more efficient and accurate.

[0096] Supplement for replacing soft aluminum film roll during work, such as Figure 7 As shown, first, if the aluminum film on the upper fixing frame 4 enters the work, it is necessary to make the aluminum film pass through the arc bead 21 at position B. At this time, relative sliding occurs between the aluminum film, the arc bead 21 and the arc groove 20. At the same time, the end of the lower aluminum film is passed through the arc bead 21 and the arc groove 20 at position C until the end of the lower aluminum film is located in the upper area of ​​the welding plate 17, and the position of the aluminum film can be fixed. When the upper aluminum film is about to be used up, until the tail end of the aluminum film enters the area of ​​the welding plate 16, the second electric cylinder 19 at position B can be started to drive the adjustment frame 18 to move, thereby adjusting the position of the arc bead 21, and fixing the aluminum film through the cooperation of the arc bead 21 and the arc groove 20. Then, the first electric cylinder 14 is immediately started, and the first electric cylinder 14 drives the lower welding frame 15 to move until the welding The end of the aluminum film on the plate 17 is docked with the tail end of the aluminum film on the welding plate 16 to ensure a tight fit, and then the ultrasonic welding machine 13 is started for welding, and then the third electric cylinder 22 at B is retracted, so that the arc pressure strip 21 at B is separated from the aluminum film, and then the first electric cylinder 14 is retracted to drive the lower welding frame 15 to move downward for a distance, which is less than the stroke of the second electric cylinder 19, and then the second electric cylinder 19 at D is started to adjust the arc pressure strip 21 at D to above the aluminum film, and the third electric cylinder 22 at D is started to push the corresponding arc pressure strip 21 out, and then the second electric cylinder 19 at D is retracted so that the arc pressure strip 21 limits the aluminum film between the arc groove 20 at D and the arc pressure strip 21, and does not affect the normal movement of the aluminum film, and then the used aluminum film roll on the upper fixed frame 4 is taken down and replaced with a new aluminum film roll.

[0097] When the lower aluminum film roll is about to be used up, the upper aluminum film roll is replaced first, and then the end of the upper aluminum film is passed through the gap between the arc pressure strip 21 and the arc groove 20 at A until the upper aluminum film is located in the area of ​​the welding plate 16, and the position of the aluminum film can be fixed. When the lower aluminum film is about to be used up, until the tail end of the aluminum film enters the area of ​​the receiving plate 17, the second electric cylinder 19 at D is started to fix the lower aluminum film through the arc pressure strip 21, and then the first motor 6 is started to push the lower welding frame 15 to move until the tail end of the aluminum film on the receiving plate 17 is docked with the end of the aluminum film on the welding plate 16, and ensure that Tightly fit, then start the ultrasonic welding machine 13 for welding. After welding is completed, retract the first electric cylinder 14, drive the lower welding frame 15 to move downward a distance, and then start the second electric cylinder 19 at B, adjust the arc bead 21 at B to under the aluminum film, start the third electric cylinder 22 at B, push the corresponding arc bead 21 out, and then retract the second electric cylinder 19 at B, so that the arc bead 21 limits the aluminum film between the arc groove 20 and the arc bead 21 at B, and does not affect the normal movement of the aluminum film, then take down the used aluminum film roll on the lower fixed frame 4 and replace it with a new aluminum film roll.

[0098] By repeating the above steps, the aluminum film can be quickly replaced without stopping the installation process of the aluminum film and the bottle cap, while ensuring the neatness and tightness of the two sections of aluminum film docking, ensuring the stability of the production process and the consistency of product quality.

[0099] like Figure 9 、 Figure 10 As shown, the continuous stamping assembly is installed on the stamping frame 3, which is used to stamp the soft aluminum film into the inside of the bottle cap. The continuous stamping assembly includes a positioning frame 23, a supporting frame 24, a fourth electric cylinder 25, a fifth electric cylinder 26, a connecting frame 27, a stamping rod 28 and a stamping hole 29. The positioning frame 23 is fixedly installed on the stamping frame 3, the positioning frame 23 is located at the upper part of the straight section, and the supporting frame 24 is arranged on the upper part of the positioning frame 23. Two fourth electric cylinders 25 are fixedly installed on the inner bottom wall of the equipment frame 1, and the output ends of the two fourth electric cylinders 25 are respectively fixedly connected to the two ends of the bottom of the supporting frame 24, and the fifth electric cylinder 26 is fixedly installed inside the supporting frame 24. The output end of the fifth electric cylinder 26 is fixedly installed with a connecting frame 27, and three stamping rods 28 are fixedly installed on the connecting frame 27 at equal distances. Three stamping holes 29 are provided on the positioning frame 23 and the arc-shaped guide frame 8, and the stamping holes 29 correspond to the stamping rods 28.

[0100] Specifically, when stamping the aluminum film, the fourth electric cylinder 25 is started to drive the supporting frame 24 to rise, so that the punching rod 28 is aligned with the punching hole 29, and then the fourth electric cylinder 25 is retracted, so that the punching rod 28 enters the punching hole 29, and then the fifth electric cylinder 26 is started to push the connecting frame 27 to drive the punching rod 28 to press down, and the aluminum film is accurately stamped into the inside of the bottle cap to ensure that the aluminum film and the bottle cap are tightly combined. After the stamping is completed, the supporting frame 24 is pushed up by the fourth electric cylinder 25, and the fifth electric cylinder 26 is retracted at the same time. At this time, the punching rod 28 is separated from the punching hole 29, and a stamping cycle is completed. During the stamping process, the electric cylinders work together to ensure uniform stamping force, prevent the aluminum film from tearing or deformation, and ensure the quality of bottle cap packaging.

[0101] like Figure 11 As shown, the feeding assembly is installed on the punching frame 3 and is used for loading and unloading bottle caps. The feeding assembly includes a mounting plate 30, a feeding plate 31, a feeding trough 32, a third motor 33, a discharge trough 34 and a discharge rack 35. The mounting plate 30 is fixedly mounted on the punching frame 3, and the feeding plate 31 is rotatably mounted on the mounting plate 30. The feeding plate 31 is circularly provided with multiple groups of feeding troughs 32 at equal angles, and each group of feeding troughs 32 is provided with three feeding troughs 32. The feeding troughs 32 are adapted to the punching rod 28. The third motor 33 is fixedly mounted on the punching frame 3, and the output end of the third motor 33 is fixedly connected to the feeding plate 31. A discharge trough 34 is provided on the mounting plate 30, and a discharge rack 35 is installed on the punching frame 3. The discharge rack 35 is located at the bottom of the discharge trough 34.

[0102] Specifically, when installing aluminum film on the bottle caps, the feeding equipment is used to feed the bottle caps side by side into a group of feeding troughs 32, that is, three bottle caps are fed into the corresponding feeding troughs 32 at the same time, and then the third motor 33 is started to drive the feeding tray 31 to rotate intermittently in the installation tray 30. Three bottle caps will enter the feeding troughs 32 at corresponding positions each time the feeding tray 31 rotates, and three bottle caps will enter the lower part of the positioning frame 23 each time the feeding tray 31 stops. The three bottle caps in this area correspond to the three punching holes 29 on the positioning frame 23 respectively, and can be stamped and installed. After the aluminum film is installed, the bottle caps will fall into the discharge rack 35 when passing through the discharge trough 34 as the feeding tray 31 rotates. By setting a discharge device in the discharge rack 35, the bottle caps with the aluminum film installed can be sent to the next link.

[0103] The working principle or usage process of this application is as follows:

[0104] After completing the assembly of the inner and outer covers, start assembling the cover and the aluminum film. Before assembling the cover and the aluminum film, first install the aluminum film roll to be used and place the aluminum film roll on the fixing frame 4. Both fixing frames 4 are equipped with aluminum film rolls. The sleeve of the aluminum film roll is fixed on the fixing frame 4. Then, the mounting frame 5 is installed on the fixing frame 4 in the form of a threaded connection, thereby fixing the axial position of the aluminum film roll and facilitating disassembly and assembly.

[0105] After the end of the aluminum film on one of the aluminum film rolls passes through the corresponding arc groove 20 and the arc pressure strip 21, the end of the aluminum film passes through the two guide rollers 7, then bypasses the lower part of the pressing frame 9, and can pass into the straight section of the arc guide frame 8 until it enters between the two feed rollers 11. The two feed rollers 11 clamp the aluminum film. When it is necessary to drive the aluminum film to move, start the second motor 12. The second motor 12 drives one of the feed rollers 11 to rotate, thereby driving the aluminum film to move with the cooperation of the other feed roller 11. During the movement, the pressing frame 9 and the aluminum film maintain relative sliding, and the aluminum film slides with the arc section of the arc guide frame 8 under the action of the gravity of the pressing frame 9.

[0106] At this time, the aluminum film is installed on the bottle caps synchronously. At this time, the bottle caps are fed into a group of feeding troughs 32 side by side through the feeding equipment, that is, three bottle caps are fed into the corresponding feeding troughs 32 at the same time, and then the third motor 33 is started to drive the feeding tray 31 to rotate intermittently in the installation tray 30. Three bottle caps will enter the feeding troughs 32 at the corresponding positions each time they rotate, and three bottle caps will enter the lower part of the positioning frame 23 each time they stop. The three bottle caps in this area correspond to the three punching holes 29 on the positioning frame 23, respectively, and can be stamped and installed. At this time, the fourth electric cylinder 25 is started to drive the carrying frame 24 to rise, so that the punching rod 28 is aligned with the punching hole 29, and then the fourth electric cylinder 25 is retracted, so that the punching rod 28 enters the punching hole 29, and then the fifth electric cylinder 26 is started to push the connecting frame 27 to drive The punching rod 28 is pressed down to accurately punch the aluminum film into the inside of the bottle cap to ensure that the aluminum film is tightly combined with the bottle cap. After the punching is completed, the fourth electric cylinder 25 pushes the supporting frame 24 to rise, and the fifth electric cylinder 26 is retracted at the same time. At this time, the punching rod 28 disengages from the punching hole 29, and a punching cycle is completed. At the same time, the first motor 6 is started, and the first motor 6 drives the fixing frame 4 and the mounting frame 5 to rotate, so that the aluminum film on the corresponding aluminum film roll is removed for easy installation operation. During the stamping process, the electric cylinders work together to ensure uniform punching force, prevent the aluminum film from tearing or deforming, and ensure the packaging quality of the bottle cap. After the aluminum film is installed, the bottle cap will fall into the discharge rack 35 when passing through the discharge chute 34 as the feed tray 31 rotates. By arranging a discharge device in the discharge rack 35, the bottle cap with the aluminum film installed can be sent to the next link.

[0107] When the aluminum film on the upper fixing frame 4 is about to be used up, the end of the aluminum film roll on the lower fixing frame 4 is placed on the welding frame 15 on the first electric cylinder 14 until the end of the aluminum film roll is located in the area of ​​the welding plate 17. At this time, the aluminum film is fixed to the position on the welding plate 17 by the arc groove 20 and the arc pressure strip 21. When the aluminum film roll entering the working position is about to be used up, the tail end of the aluminum film enters the area of ​​the welding plate 16. At this time, the aluminum film on the welding frame 15 at the bottom of the ultrasonic welding machine 13 is fixed, and then the first electric cylinder 14 is started. The first electric cylinder 14 pushes the corresponding welding frame 15 to move until the new and old sections of aluminum film are docked, and the two sections of aluminum film are pressed by the welding plate 16 and the welding plate 17. At this time, the ultrasonic welding machine 13 is started to dock the two sections of aluminum film together, and then the first electric cylinder 14 is retracted.

[0108] Through the cooperation of the second electric cylinder 19 and the third electric cylinder 22 at four positions ABCD, the new and old sections of aluminum film can be quickly and accurately docked without stopping work, thereby improving work efficiency.

[0109] Example 2: This example is based on an automatic assembly device for the inner and outer covers of a sauce bottle cap, and also proposes an automatic assembly method for the inner and outer covers of a sauce bottle cap. The specific assembly process is as follows:

[0110] The first step is injection molding of the outer cover, which is performed using a horizontal injection molding machine to form the outer cover;

[0111] The second step is cap sorting. The outer caps after injection molding are transported to three vibration plates through the conveyor track for cap sorting.

[0112] The fourth step is feeding, which is transferred from the vibrating plate to the feeding track. There are multiple air blowing ports inclined above and below the feeding track. The upper air blowing port blows hot air to keep the connection of the outer cover at a certain temperature to prevent the connection of the outer cover from being too hard due to too fast cooling and breaking during the subsequent closing process. The wind blown out by the upper and lower air blowing ports drives the outer cover to move forward. There are also 3 feeding tracks. A mobile feeding channel is provided in the middle of the feeding track. A sensor is provided on each feeding track. When the outer covers on the feeding track reach the sensor position, the number of outer covers on the feeding track reaches a predetermined number. The mobile feeding channel moves to the corresponding feeding track, so that the outer covers that have reached a predetermined number move forward through the mobile feeding channel until they move to the closing mechanism.

[0113] The fifth step is to close the cover. A plurality of fixed claws are provided on the outer periphery of the turntable to fix the outer cover. A closing block is also provided on the outer periphery of the turntable. The outer cover passes through the closing block under the drive of the turntable to close the outer cover. The closed outer cover is then transported to the inner and outer cover assembly mechanism.

[0114] The sixth step is assembly. The soft cover and the soft cover bracket are first assembled together in the inner and outer cover assembly mechanism. The inner and outer cover assembly mechanism includes a turntable. Several positioning pins are provided on the outer peripheral side of the turntable. One of the vibration disks feeds the soft cover onto the positioning pins. A cross scratch is provided in the middle of the soft cover. The other vibration disk also feeds the soft cover bracket onto the positioning pins and is located above the soft cover. The pressure rod above the turntable is pressed down to combine the soft cover bracket and the soft cover together. The combined two are taken out of the positioning pins and moved upward. The pressure rod is pressed down again to press the soft cover bracket and the soft cover into the closed outer cover to complete the assembly of the inner and outer covers. The assembled covers are transported to the soft aluminum film assembly mechanism.

[0115] The seventh step is loading. The bottle caps are fed into a group of feeding troughs 32 side by side through the feeding equipment, that is, three bottle caps are fed into the corresponding feeding troughs 32 at the same time, and then the third motor 33 is started to drive the feeding tray 31 to rotate intermittently in the mounting tray 30. Each time it rotates, three bottle caps enter the feeding troughs 32 at the corresponding positions. At the same time, each time it stops, three bottle caps enter the lower part of the positioning frame 23. The three bottle caps in this area correspond to the three punching holes 29 on the positioning frame 23, and can be punched and installed.

[0116] Step 8: Stamping. Start the fourth electric cylinder 25 to drive the carrier frame 24 to rise, align the punching rod 28 with the punching hole 29, then retract the fourth electric cylinder 25 so that the punching rod 28 enters the punching hole 29. Then start the fifth electric cylinder 26 to push the connecting frame 27 to drive the punching rod 28 downward, accurately punching the aluminum film into the inside of the bottle cap to ensure that the aluminum film and the bottle cap are tightly combined. After the stamping is completed, the carrier frame 24 is pushed up by the fourth electric cylinder 25, and the fifth electric cylinder 26 is retracted at the same time. At this time, the punching rod 28 is separated from the punching hole 29, and a stamping cycle is completed.

[0117] The ninth step is to load the aluminum film. The first motor 6 is started synchronously to drive the fixing frame 4 and the mounting frame 5 to rotate, so that the aluminum film on the corresponding aluminum film roll is removed to facilitate the installation operation. At the same time, the second motor 12 is started. The second motor 12 drives one of the feed rollers 11 to rotate, thereby driving the aluminum film to move with the cooperation of the other feed roller 11.

[0118] The tenth step is to replace the aluminum film. Without stopping the Azhuang aluminum film, the second electric cylinder 19 and the third electric cylinder 22 at four points ABCD cooperate to quickly and accurately connect the new and old sections of aluminum film, thereby improving work efficiency.

[0119] The eleventh step is unloading. After the aluminum film is installed, the bottle caps will fall into the discharge rack 35 when passing through the discharge chute 34 as the feed tray 31 rotates. By setting a discharge device in the discharge rack 35, the bottle caps with the aluminum film installed can be sent to the next link to complete the bottle cap assembly.

[0120] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
