Description

Technical Field

[0001] This utility model relates to the field of bottle and can sealing technology, and more specifically to a bottle and can positioning mechanism for an aluminum foil sealing machine. Background Technology

[0002] Aluminum foil electromagnetic induction sealing technology has been widely used in the packaging processes of food, pharmaceuticals, cosmetics, and chemical products due to its excellent sealing performance, strong anti-counterfeiting properties, and convenient opening. Its basic principle is as follows: a composite gasket with aluminum foil is placed inside the bottle opening. When the container is passed through a high-frequency electromagnetic field, the aluminum foil layer generates eddy currents and heats up, instantly melting the heat-sealing coating underneath and bonding it to the bottle opening. After cooling, a seal is achieved.

[0003] In the entire sealing equipment, the bottle positioning mechanism is a crucial component. Its core function is to precisely constrain the position and orientation of the container when it is conveyed to the area directly below the sealing head, ensuring that the center line of the bottle mouth coincides with the electromagnetic field center axis of the sealing coil.

[0004] However, in order to provide the necessary physical space and pressure relief channels during the heat sealing process, it is necessary to ensure that the outer cap is loose when sealing the aluminum foil. When the conveyor belt is transporting the bottles, the vibration of the machine during operation can cause the cap to shift, which can easily lead to misalignment of the aluminum foil. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a bottle and can positioning mechanism for an aluminum foil sealing machine, so as to solve the problem that the bottle cap will shift due to the vibration of the machine during the conveyor belt transporting bottles and cans.

[0006] This utility model provides the following technical solution: a bottle and can positioning mechanism for an aluminum foil sealing machine, including a bottle and can conveyor belt and a sealing equipment body installed on one side of the bottle and can conveyor belt, and outer cover straightening components are provided on both sides of the bottle and can conveyor belt. The outer cap straightening assembly includes limiter conveyor belts symmetrically arranged on both sides of the bottle conveyor belt. Each limiter conveyor belt has two positioning cylinders symmetrically arranged on both sides away from the bottle conveyor belt. The positioning cylinder at the front end is fixedly connected to the limiter conveyor belt through a bracket. Several limiter bodies are evenly arranged along the axis on the surface of the limiter conveyor belt. The limiter body has a contour groove for the bottle body and the outer cap on the side facing the bottle. A limit frame is fixedly connected to the top surface of the limiter body. An insert block is fixedly connected to the piston rod of the positioning cylinder. The insert block is inserted into the inside of the limit frame.

[0007] As a further embodiment of this utility model, each of the limiting device bodies has a magnet embedded on the side facing the bottle or can, and the two opposing limiting device bodies are attracted to each other by the magnet.

[0008] As a further embodiment of this utility model, two shielding cylinders are symmetrically fixedly connected to the surface of the main body of the sealing device. Each shielding cylinder is fixedly connected to a baffle via a bracket, and the baffle is in close contact with the bottle or can.

[0009] As a further embodiment of this utility model, a lifting cylinder is provided at the bottom of the positioning cylinder at the rear end, and the piston rod of the lifting cylinder is fixedly connected to the positioning cylinder at the rear end.

[0010] As a further embodiment of this invention, the insert block of the positioning cylinder push rod located at the rear end is made of rubber.

[0011] As a further embodiment of this utility model, a limiting cone is fixedly connected to the bottom surface of the rear baffle, and a slot corresponding to the limiting cone is provided on the top surface of the limiting device body.

[0012] As a further embodiment of this utility model, the top surface of the bottle conveyor belt is symmetrically fixed with two guide rods by bolts, and the bottles are located between the two guide rods.

[0013] As a further embodiment of this utility model, each of the limiter conveyor belts has a photoelectric sensor mounted on its top surface via a bracket, with the lens of the photoelectric sensor facing the foremost limiter body.

[0014] The technical effects and advantages of this utility model are as follows: 1. This utility model, through the symmetrically arranged limiter body and its contour groove on both sides, can accurately clamp and wrap the bottle cap from both sides. Combined with the magnetic attraction force, it ensures that the bottle cap remains stable and centered during the conveying and sealing process, effectively preventing the bottle cap from shifting during sealing, thereby significantly improving the tightness and consistency of the seal and ensuring the packaging quality of the product.

[0015] 2. This utility model can reliably separate two mutually adsorbed limiter bodies by cooperating with the rear lifting cylinder, the limiting cone and the slot; combined with the characteristics of the rubber plug and the setting of the stop block, the unloading and recycling of the limiter body are realized.

[0016] 3. This utility model guides and restricts the movement path of bottles and cans by using bottle guide rods, effectively preventing bottles and cans from tipping over or shifting due to vibration or collision during the conveying process, thus reducing product damage and equipment operation risks.

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Reference Figures 1-8 This utility model provides a bottle and can positioning mechanism for an aluminum foil sealing machine, including a bottle and can conveyor belt 1 and a sealing equipment body 2 installed on one side of the bottle and can conveyor belt 1. Outer cover straightening components are provided on both sides of the bottle and can conveyor belt 1. The outer cap straightening assembly includes limiter conveyor belts 3 symmetrically arranged on both sides of the bottle conveyor belt 1. Each limiter conveyor belt 3 has two positioning cylinders 7 symmetrically arranged on the side away from the bottle conveyor belt 1. The positioning cylinder 7 at the front end is fixedly connected to the limiter conveyor belt 3 through a bracket. Several limiter bodies 4 are evenly arranged along the axis on the surface of the limiter conveyor belt 3. The side of the limiter body 4 facing the bottle has a contour groove that matches the bottle body and the outer cap. A limit frame 9 is fixedly connected to the top surface of the limiter body 4. An insert block 8 is fixedly connected to the piston rod of the positioning cylinder 7. The insert block 8 is inserted into the inside of the limit frame 9.

[0028] Each limiter body 4 has a magnet embedded on the side facing the bottle or can, and two opposite limiter bodies 4 are attracted to each other by the magnet.

[0029] A lifting cylinder 10 is provided at the bottom of the rear positioning cylinder 7. The piston rod of the lifting cylinder 10 is fixedly connected to the rear positioning cylinder 7. The insert block 8 of the push rod of the rear positioning cylinder 7 is made of rubber.

[0030] A limiting cone 11 is fixedly connected to the bottom surface of the rear end baffle 6, and a slot 13 corresponding to the limiting cone 11 is opened on the top surface of the limiter body 4.

[0031] When the outer cap of the bottle needs to be stabilized before sealing, the bottle is placed on the top surface of the bottle conveyor belt 1, so that the bottle and the insert block 8 are on the same axis. Then, the front positioning cylinder 7 is activated, which causes the insert block 8 to insert into the inside of the limiting frame 9. Subsequently, the limiting device body 4 will move towards the bottle due to the force applied by the positioning cylinder 7 until the limiting device bodies 4 on both sides are in contact with the bottle. The two limiting device bodies 4 will attract each other due to magnetism, thereby achieving the positioning of the outer cap. Then, the bottle is moved towards the sealing equipment body 2 by the bottle conveyor belt 1, and the positioning of the outer cap is achieved by the two limiting device bodies 4.

[0032] When the bottle passes over the sealing equipment body 2, it stops moving when it is aligned with the axis of the rear lifting cylinder 10. Then, the rear positioning cylinder 7 is activated, which moves the rubber block 8 toward the limiter body 4 until it is inserted into the limit frame 9. Then, the lifting cylinder 10 is activated, causing the rear positioning cylinder 7 to move upward. The limiter body 4 also moves upward until the limit cone 11 is inserted into the slot 13. The two limiter bodies 4 are separated by the cooperation of the limit cone 11 and the slot 13. Then, the rear positioning cylinder 7 retracts the limiter body 4. Because there is a stop block fixedly connected to the side of the limiter conveyor belt 3 adjacent to the rubber block 8, when the rear positioning cylinder 7 retracts the limiter body 4, the limiter body 4 will be blocked by the stop block, thus detaching from the surface of the rubber block 8 and falling onto the surface of the limiter conveyor belt 3.

[0033] Because the insert 8 is made of rubber, when the limiting cone 11 separates from the limiter body 4, the insert 8 will be appropriately compressed, and the rubber material has greater friction and is more stable.

[0034] In this utility model, two shielding cylinders 5 are symmetrically fixedly connected to the surface of the sealing equipment body 2. The shielding cylinders 5 are fixedly connected to baffles 6 by brackets, and the baffles 6 are in close contact with the bottles and cans.

[0035] When the bottle / can is coaxial with the positioning cylinder 7 at the rear or front end, the blocking cylinder 5 is activated. The piston rod of the blocking cylinder 5 will drive the baffle 6 to move downward, thereby blocking the bottle / can and making it easier to place or remove the limiter body 4.

[0036] In this invention, the top surface of the bottle conveyor belt 1 is symmetrically fixed with two guide rods 14 by bolts, and the bottles are located between the two guide rods 14.

[0037] The two guide rods 14 can limit the body of the bottle to prevent it from shifting due to vibration.

[0038] In this utility model, each limiter conveyor belt 3 has a photoelectric sensor 12 mounted on its top surface via a bracket, with the lens of the photoelectric sensor 12 facing the foremost limiter body 4.

[0039] After the front positioning cylinder 7 places the limiter body 4, the photoelectric sensor 12 will detect that the front limiter body 4 has disappeared. Then, the limiter conveyor belt 3 will be started, and the limiter conveyor belt 3 will move the limiter body 4 forward until the photoelectric sensor 12 detects the presence of the limiter body 4, at which point the movement of the limiter conveyor belt 3 will stop.

[0040] It should be noted that the conveyor belt model in this application is TF-SSD, which is only used for moving goods. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0041] It should be noted that in this application, the cylinder is a power actuator that converts the pressure energy of compressed air into mechanical energy. By controlling the gas in and out, it drives the piston to perform linear reciprocating motion. It can be used in conjunction with a magnetic switch, proximity switch or photoelectric switch to achieve precise control of the extension and retraction displacement of the cylinder piston rod. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0042] It should be noted that the main part number of the sealing equipment in the application is JN2500. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0043] It should be noted that the photoelectric sensor 12 is model E3Z-D61. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0044] The use of this utility model involves the following steps: S1: When the bottle is coaxial with the positioning cylinder 7 at the rear or front end, the blocking cylinder 5 is activated. The piston rod of the blocking cylinder 5 will drive the baffle 6 to move downward, thereby blocking the bottle, making it easier to place or remove the limiter body 4. S2: When it is necessary to stabilize the outer cap of the bottle before sealing, place the bottle on the top surface of the bottle conveyor belt 1, so that the bottle and the insert block 8 are on the same axis. Then, start the front positioning cylinder 7. The front positioning cylinder 7 will cause the insert block 8 to be inserted into the inside of the limiting frame 9. Then, the limiting device body 4 will move towards the bottle due to the force applied by the positioning cylinder 7 until the limiting device bodies 4 on both sides are in contact with the bottle. The two limiting device bodies 4 will attract each other due to magnetism, thereby achieving the positioning of the outer cap. Then, the bottle is moved towards the sealing equipment body 2 by the bottle conveyor belt 1, and the positioning of the outer cap is achieved by the two limiting device bodies 4. S3: When the bottle passes over the sealing equipment body 2, until it is aligned with the axis of the rear lifting cylinder 10, the bottle stops moving. Then, the rear positioning cylinder 7 is activated, which drives the rubber block 8 to move towards the limiter body 4 until the rubber block 8 is inserted into the limit frame 9. Then, the lifting cylinder 10 is activated, which moves the rear positioning cylinder 7 upward. The limiter body 4 also moves upward until the limit cone 11 is inserted into the slot 13. Through the cooperation of the limit cone 11 and the slot 13, the two limiter bodies 4 are separated. Then, the rear positioning cylinder 7 retracts the limiter body 4. Because there is a stop block fixedly connected to the side of the limiter conveyor belt 3 adjacent to the rubber block 8, when the rear positioning cylinder 7 retracts the limiter body 4, the limiter body 4 will be blocked by the stop block, thus detaching from the surface of the rubber block 8 and falling onto the surface of the limiter conveyor belt 3. S4: After the front positioning cylinder 7 places the limiter body 4, the photoelectric sensor 12 will detect that the front limiter body 4 has disappeared, and then start the limiter conveyor belt 3. The limiter conveyor belt 3 will move the limiter body 4 forward until the photoelectric sensor 12 detects the presence of the limiter body 4, and then stop the movement of the limiter conveyor belt 3.
