Description

Technical Field

[0001] This application relates to the field of milk powder sealing machine technology, and more specifically, to a sealing machine for milk powder production and processing. Background Technology

[0002] Sealing milk powder cans is a crucial step in the milk powder production process. Traditional semi-automatic can sealing machines often rely too heavily on manual operation, resulting in slow feeding and unloading, low manual sealing efficiency, and difficulty in meeting the needs of large-scale production. Furthermore, they are labor-intensive, and the equipment lacks precision, especially when processing batches of different milk powder cans of varying sizes. The feeding device cannot accurately control the position and height of the cans, leading to deviations during sealing and inconsistent sealing quality. This can result in problems such as incomplete can lid seals, affecting the product's shelf life and quality. Additionally, the lack of protective enclosures for some high-speed moving parts of the sealing machine increases the risk of safety accidents. Therefore, we propose a new can sealing machine for milk powder production. Utility Model Content

[0003] 1. Technical problems to be solved The purpose of this application is to provide a can sealing machine for milk powder production and processing, which solves the technical problems mentioned in the background art. The can sealing machine has a compact and reasonable layout, occupies little space, is suitable for flexible arrangement in the production workshop, has a protective cover for safety, uses an electric cylinder to accurately lift the material, and is adapted to multiple can sizes with an adjustable limit mechanism for accurate positioning. During sealing, the dual motors work together and multiple components are linked, and the intermittent feeder supplies material on demand, perfectly matching the sealing rhythm. Combined with the conveyor belt guiding along the arc plate, it achieves high-quality and accurate can sealing processing, improving overall efficiency, stabilizing quality, reducing labor intensity, and helping enterprises to achieve efficient production.

[0004] 2. Technical Solution This application provides a can sealing machine for milk powder production and processing, comprising: a machine housing, on which a bracket, a conveyor belt mechanism for conveying milk powder cans, a top material mechanism for supporting milk powder cans, and a limiting mechanism for limiting the maximum lifting limit of the milk powder cans are mounted. The bracket includes a T-shaped seat fixed to the upper surface of the machine housing and a top shell fixed to the upper end of the T-shaped seat. A can sealing mechanism for sealing the can lids of the milk powder cans and an intermittent feeder for intermittently conveying the milk powder cans on the conveyor belt to the can sealing area are mounted on the bracket. A U-shaped protective cover is fixed to the top shell by bolts to protect the can sealing mechanism.

[0005] By adopting the above technical solution, the can sealing machine uses a chassis as the carrier and basic frame of the entire equipment. A bracket is installed on the chassis to support the sealing mechanism and intermittent conveyor. During processing, a conveyor belt mechanism transports the milk powder cans to the designated position in an orderly manner. Then, the intermittent conveyor transports the milk powder cans to be sealed one by one to the sealing area. The top material mechanism lifts the milk powder cans in the sealing area to a suitable height so that the sealing mechanism can perform accurate sealing operations. A limit mechanism is set to restrict the maximum lifting limit of the milk powder cans, and the maximum lifting limit can be pre-adjusted according to the specifications and dimensions of the milk powder cans to ensure the vertical positioning accuracy of the cans. This ensures that each milk powder can enters the sealing area at the appropriate time for precise sealing, greatly improving processing efficiency. A U-shaped protective cover is installed on the top shell to surround some high-speed components of the sealing mechanism, mainly for safety protection purposes, to prevent operators from accidentally touching the high-speed rotating sealing components and causing danger.

[0006] Optionally, the top material mechanism includes an electric cylinder fixed inside the machine housing. The piston rod of the electric cylinder moves through the machine housing and is fixedly connected to a tray. A circular storage groove is provided on the upper surface of the machine housing at the sealing area. When the piston rod of the electric cylinder is retracted and reset, the tray is completely embedded in the circular storage groove.

[0007] By adopting the above technical solution, the piston rod of the electric cylinder can drive the tray to make linear reciprocating motion. The circular storage groove set on the upper surface of the machine box cooperates with the tray. When the piston rod of the electric cylinder is retracted and reset, the tray can be completely embedded in the circular storage groove, so that the milk powder can be smoothly transported or output from the tray.

[0008] Optionally, the limiting mechanism includes an arc-shaped guide plate fixed to the upper surface of the chassis and a fixing block fixed to the arc-shaped guide plate. A J-shaped limiting plate is slidably inserted into the fixing block, and a threaded rod is threadedly installed on the fixing block. The upper end of the threaded rod is rotatably connected to the J-shaped limiting plate, and the tray rises and abuts against one end of the J-shaped limiting plate.

[0009] By adopting the above technical solution, the shape of the arc-shaped guide plate conforms to the movement trajectory of the milk powder can, enabling the milk powder can to smoothly enter the sealing area along the predetermined path. The height position of the J-shaped limiting plate can be precisely adjusted by rotating the threaded rod. When the tray rises, the tray will abut against one end of the J-shaped limiting plate, thereby limiting the maximum lifting limit of the tray and indirectly controlling the height position of the milk powder can, ensuring the accuracy and consistency of the sealing operation.

[0010] Optionally, the two ends of the arc-shaped guide plate are fixedly connected to the guard plate of the conveyor belt mechanism, and the guard plate of the conveyor belt mechanism is provided with a notch at the arc-shaped guide plate, and the conveyor belt of the conveyor belt mechanism is flush with the upper surface of the machine box.

[0011] By adopting the above technical solution, the two ends of the arc-shaped guide plate are fixedly connected to the guard plate of the conveyor belt mechanism, and the guard plate of the conveyor belt mechanism is provided with a notch at the arc-shaped guide plate. This ensures that the milk powder cans on the conveyor belt can smoothly pass through the arc-shaped guide plate at the notch and enter the sealing area without being obstructed by the guard plate. At the same time, the conveyor belt of the conveyor belt mechanism is flush with the upper surface of the machine box, which enables the milk powder cans to maintain a stable horizontal state during the conveying process, reduces the bumps and tilts caused by height differences, and further improves the stability and accuracy of the conveying.

[0012] Optionally, the sealing mechanism includes a second motor fixed to one end of the top shell and a toothed belt assembly rotating inside the top shell. The output end of the second motor is connected to one gear of the toothed belt assembly. The other gear of the toothed belt assembly is fixed to a vertical shaft, which rotates on the top shell and has a pressure cap fixed at its bottom end. The sealing mechanism also includes a third motor fixed to a T-shaped seat. The output end of the third motor is connected to a large gear, which meshes with two small gears. Each small gear has a rotating rod fixed to it. Each rotating rod has a rotating plate fixed to it, and the bottom end of the rotating rod rotates on the T-shaped seat. A pressure wheel is rotatably mounted on the end of the rotating plate away from the rotating rod via a shaft. A spring is fixed between the rotating plates.

[0013] By adopting the above technical solution, motor 2 serves as the power source for driving the toothed belt assembly. The toothed belt assembly drives the vertical shaft to rotate, causing the pressure cap to apply rotational pressure to the lid of the milk powder can. The output end of motor 3 drives the large gear to rotate. Because the large gear meshes with two small gears, the large gear drives the two small gears to rotate, causing the two rotating plates to rotate in opposite directions. As a result, the pressure wheel installed at the end of the rotating plate will press against the edge of the lid on the milk powder can. Combined with the rotational pressure applied by the pressure cap, the edge of the milk powder can is rolled and sealed. In order to ensure that the pressure wheel can always maintain appropriate pressure on the edge of the can, a spring is also installed between the rotating plates. The entire sealing mechanism achieves efficient and precise sealing of the milk powder can through the coordinated work of multiple components.

[0014] Optionally, the intermittent feeder includes a motor fixed to the top shell, the output shaft of the motor movably passes through the top shell and is fixed with a feeding disc, the feeding disc is located above the conveyor belt and has multiple U-shaped grooves evenly arranged along the circumference, and the feeding disc rotates to fit against the inner wall of the arc-shaped guide plate.

[0015] By adopting the above technical solution, the output shaft of motor one drives the conveyor plate to rotate. Each U-shaped groove of the conveyor plate can accurately accommodate a milk powder can through the circumferential design. When the conveyor plate rotates, the U-shaped groove will pass through the position of the milk powder can on the conveyor belt in turn, and transport the milk powder can one by one to the area directly below the sealing area.

[0016] Optionally, the front end of the chassis is provided with a slope, and a control switch is installed on the slope of the chassis for electrically controlling the drive equipment.

[0017] By adopting the above technical solution, the front of the chassis is designed with a slope, which conforms to ergonomic principles, making it convenient for operators to stand and operate. The control switch installed on the slope integrates various control function buttons and display screens, allowing operators to easily start, stop, adjust speed, and set parameters. The control switch uses electrical control to drive the various components of the equipment, realizing automated control and management, and improving production efficiency and ease of operation.

[0018] 3. Beneficial effects One or more technical solutions provided in this application have at least the following technical effects or advantages: 1. Through the precise coordination of the conveyor belt mechanism, the top material mechanism, the intermittent feeder, and the sealing mechanism, milk powder cans can be intermittently transported to the sealing area and sealed one by one with high efficiency and precision. By designing a limiting mechanism, the height of the J-shaped limiting plate can be precisely adjusted in advance according to the specifications and dimensions of the milk powder cans, so that the lifting height of the tray holding the milk powder cans can be precisely adjusted, ensuring that each milk powder can be accurately lifted to the same height, guaranteeing the accuracy and consistency of sealing, greatly improving the product qualification rate, and having strong versatility and flexibility, making it convenient for enterprises to adjust according to different production needs; 2. The can sealing machine has a compact and reasonable layout, occupies little space, and is suitable for flexible arrangement in the production workshop. The U-shaped protective cover fixed on the top shell protects the can sealing mechanism, effectively preventing operators from accidentally coming into contact with the high-speed rotating can sealing components, avoiding safety accidents, and also reducing the interference of external factors on the can sealing process, ensuring the stability and reliability of the can sealing operation.

[0020] The present application will be further described in detail below with reference to the accompanying drawings. Reference Figures 1 to 5 This application provides a can sealing machine for milk powder production and processing, comprising: a chassis 1, on which a bracket 2, a conveyor belt mechanism 6 for conveying milk powder cans 9, a top material mechanism 5 for lifting milk powder cans 9, and a limiting mechanism 7 for limiting the maximum lifting limit of milk powder cans 9 are mounted. The bracket 2 includes a T-shaped seat 21 fixed to the upper surface of the chassis 1 and a top shell 22 fixed to the upper end of the T-shaped seat 21. A can sealing mechanism 4 for sealing can lids 91 of milk powder cans 9 and an intermittent feeder 3 for intermittently conveying milk powder cans 9 from the conveyor belt to the can sealing area are mounted on the bracket 2. A U-shaped protective cover 10 is bolted to the top shell 22 to protect the can sealing mechanism 4. The can sealing machine uses the chassis 1 as the carrier and basic frame of the entire equipment. The bracket 2 mounted on the chassis 1 can be used to support and install the can sealing mechanism 4 and the intermittent feeder 3. During processing... The conveyor belt mechanism 6 is responsible for orderly transporting the milk powder cans 9 to the designated position. Then, the intermittent feeder 3 transports the milk powder cans 9 to be sealed one by one to the sealing area. The top material mechanism 5 lifts the milk powder cans 9 in the sealing area to a suitable height so that the sealing mechanism 4 can perform accurate sealing operations. The limit mechanism 7 is set to limit the maximum lifting limit of the milk powder cans 9. The maximum lifting limit of the milk powder cans 9 can be pre-adjusted according to the specifications and dimensions of the milk powder cans 9 to ensure the vertical position accuracy of the milk powder cans 9. This allows each milk powder can 9 to enter the sealing area at the appropriate time and perform accurate sealing processing, which greatly improves processing efficiency. The U-shaped protective cover 10 is installed on the top shell 22 to surround some of the high-speed components of the sealing mechanism 4. This is mainly for safety protection purposes to prevent operators from accidentally touching the high-speed rotating sealing components and causing danger.

[0021] Reference Figure 1 and Figure 2 The feeding mechanism 5 includes an electric cylinder 51 fixed inside the housing 1. The piston rod of the electric cylinder 51 moves through the housing 1 and is fixedly connected to a tray 52. ​​A circular storage groove 11 is provided on the upper surface of the housing 1 at the sealing area. When the piston rod of the electric cylinder 51 is retracted and reset, the tray 52 is completely embedded in the circular storage groove 11. The piston rod of the electric cylinder 51 can drive the tray 52 to perform linear reciprocating motion. The circular storage groove 11 provided on the upper surface of the housing 1 cooperates with the tray 52. ​​When the piston rod of the electric cylinder 51 is retracted and reset, the tray 52 can be completely embedded in the circular storage groove 11, so that the milk powder can 9 can smoothly transport or output the tray 52.

[0022] Reference Figure 2 and Figure 3 The limiting mechanism 7 includes an arc-shaped guide plate 71 fixed to the upper surface of the housing 1 and a fixing block 72 fixed to the arc-shaped guide plate 71. A J-shaped limiting plate 73 is slidably inserted into the fixing block 72. A threaded rod 74 is threadedly installed on the fixing block 72. The upper end of the threaded rod 74 is rotatably connected to the J-shaped limiting plate 73. The tray 52 rises and abuts against one end of the J-shaped limiting plate 73. The shape of the arc-shaped guide plate 71 conforms to the movement trajectory of the milk powder can 9, allowing the milk powder can 9 to smoothly enter the sealing area along the predetermined path. By rotating the threaded rod 74, the height position of the J-shaped limiting plate 73 can be precisely adjusted. When the tray 52 rises, the tray 52 abuts against one end of the J-shaped limiting plate 73, thereby limiting the maximum lifting limit of the tray 52, which indirectly controls the height position of the milk powder can 9, ensuring the accuracy and consistency of the sealing operation.

[0023] Reference Figure 2 and Figure 3 The arc-shaped guide plate 71 is fixedly connected to the guard plate of the conveyor belt mechanism 6 at both ends, and the guard plate of the conveyor belt mechanism 6 has a notch 61 at the arc-shaped guide plate 71. The conveyor belt of the conveyor belt mechanism 6 is flush with the upper surface of the machine box 1. The arc-shaped guide plate 71 is fixedly connected to the guard plate of the conveyor belt mechanism 6 at both ends, and the guard plate of the conveyor belt mechanism 6 has a notch 61 at the arc-shaped guide plate 71. This ensures that the milk powder can 9 on the conveyor belt can smoothly pass through the arc-shaped guide plate 71 at the notch 61 and enter the sealing area without being obstructed by the guard plate. At the same time, the conveyor belt of the conveyor belt mechanism 6 is flush with the upper surface of the machine box 1, which allows the milk powder can 9 to maintain a stable horizontal state during the conveying process, reducing the bumps and tilting caused by height differences, and further improving the stability and accuracy of the conveying.

[0024] Reference Figure 4 and Figure 5The sealing mechanism 4 includes a second motor 41 fixed to one end of the top shell 22 and a toothed belt assembly 42 rotating inside the top shell 22. The output end of the second motor 41 is connected to one gear of the toothed belt assembly 42. The other gear of the toothed belt assembly 42 is fixed to a vertical shaft 43, which rotates on the top shell 22 and has a pressure cap 44 fixed at its bottom end. The sealing mechanism 4 also includes a third motor 45 fixed to a T-shaped seat 21. The output end of the third motor 45 is connected to a large gear 46, which meshes with two small gears 47. Each small gear 47 has a rotating rod 471 fixed to it, and each rotating rod 471 has a rotating plate 48 fixed to it. The bottom end of the rotating rod 471 rotates on the T-shaped seat 21. A pressure wheel 481 is rotatably mounted on the end of the rotating plate 48 away from the rotating rod 471 via a shaft. A spring 49 is fixed between the rotating plates 48. 41 serves as the power source for the drive belt assembly 42. The drive belt assembly 42 rotates the vertical shaft 43, causing the pressure cap 44 to apply rotational pressure to the lid 91 of the milk powder can 9. The output end of the motor 3 45 drives the large gear 46 to rotate. Since the large gear 46 meshes with two small gears 47, the large gear 46 drives the two small gears 47 to rotate, causing the two rotating plates 48 to rotate in opposite directions. As a result, the pressure wheel 481 installed at the end of the rotating plate 48 presses against the edge of the lid 91 on the milk powder can 9. Combined with the rotational pressure applied by the pressure cap 44, the edge of the milk powder can 9 is rolled and sealed. In order to ensure that the pressure wheel 481 can always maintain appropriate pressure on the edge of the can, a spring 49 is also provided between the rotating plates 48. The entire sealing mechanism 4 achieves efficient and precise sealing of the milk powder can 9 through the coordinated work of multiple components.

[0025] Reference Figure 4 and Figure 5 The intermittent feeder 3 includes a motor 31 fixed on the top shell 22. The output shaft of the motor 31 moves through the top shell 22 and is fixed with a feeding disc 32. The feeding disc 32 is located above the conveyor belt and has multiple U-shaped grooves 321 evenly arranged along its circumference. The feeding disc 32 rotates to fit against the inner wall of the arc-shaped guide plate 71. The output shaft of the motor 31 drives the feeding disc 32 to rotate. Each U-shaped groove 321 of the feeding disc 32 can accurately accommodate a milk powder can 9. When the feeding disc 32 rotates, the U-shaped grooves 321 will pass through the positions of the milk powder cans 9 on the conveyor belt in sequence and transport the milk powder cans 9 one by one to the area directly below the sealing area.

[0026] Reference Figure 1 and Figure 2The front of the chassis 1 has a slope, and a control switch 8 is installed on the slope for electrically controlling the equipment. This sloped design conforms to ergonomic principles, allowing operators to operate the equipment while standing. The control switch 8, installed on the slope, integrates various control function buttons and a display screen, allowing operators to easily start, stop, adjust speed, and set parameters. The control switch 8 uses electrical control to drive the various components of the equipment, achieving automated control and management, improving production efficiency and ease of operation.

[0027] Working Principle: After the equipment is started, the conveyor belt mechanism 6 transports the milk powder cans 9 to be sealed along the conveyor belt towards the feeding tray 32. The motor 31 drives the feeding tray 32 to rotate. The U-shaped groove 321 on the feeding tray 32 accurately grabs a milk powder can 9. The milk powder can 9, located at the notch 61, gradually approaches the sealing area under the guidance of the arc-shaped guide plate 71. When the milk powder can 9 reaches directly below the sealing area, the motor 31 stops conveying and waits for the next working cycle. After receiving the signal, the electric cylinder 51 extends the piston rod, pushing the tray 52 to rise and lift the milk powder can 9 on the feeding tray 32. As the tray 52 rises, it abuts against one end of the J-shaped limiting plate 73. Since the height of the J-shaped limiting plate 73 has been preset by the threaded rod 74, the tray 52 will accurately lift the milk powder can 9 to the predetermined height and hold the cap. 44. After the milk powder can 9 is accurately positioned, motor 2 41 drives the toothed belt assembly 42 to rotate, which in turn causes the vertical shaft 43 to rotate. The pressure cap 44 moves accordingly to press the can lid 91 of the milk powder can 9. At the same time, motor 3 45 drives the large gear 46 to mesh with two small gears 47, which drives the rotating rod 471 and the rotating plate 48 to rotate. The pressure wheel 481 rolls and seals the edge of the can lid 91 under the action of the spring 49, completing the sealing operation of the milk powder can 9. After sealing, the piston rod of the electric cylinder 51 is retracted and reset, the tray 52 descends and puts the sealed milk powder can 9 back into the U-shaped groove 321 on the conveyor tray 32. As motor 1 31 starts again, the sealed milk powder can 9 is transported to the conveyor belt again and smoothly transported to the next processing step and enters the next work cycle. This process is repeated to achieve efficient semi-automatic sealing processing.
