Description
Technical Field
[0001] This utility model relates to the technical field of milk processing, and in particular to a sealing device for filling bagged milk. Background Technology
[0002] Milk is one of the oldest natural beverages, often called "white blood." It is rich in nutrients such as protein, fat, vitamins, and minerals. Bagged milk is fresh milk that has undergone pasteurization and is typically packaged in plastic bags. It is filled into these bags using a filling machine and then sealed. Existing technology publication number CN218641220U proposes a liquid packaging bag filling and sealing device. Its technical solution includes: a machine platform and a storage tank. A rotating disc is mounted on the top center of the machine platform via a rotating column. A fixed frame is mounted on the top of the machine platform near the rear surface. The storage tank is mounted on top of the fixed frame. A weighing platform is mounted on the top of the machine platform near the rotating disc. A conveyor belt A is mounted on the top of the machine platform near the weighing platform. An electric telescopic device B is mounted on the top of the machine platform near the weighing platform via a positioning plate. However, this device is only suitable for tightening the cap onto the packaging bag to seal the opening of the plastic packaging bag; it cannot guarantee the airtightness after sealing, making its practicality poor. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a sealing device for bagged milk filling that performs pre-treatment of the upper opening of the packaging bag before sealing, and detects the sealing of the packaging bag to facilitate timely removal in case of leakage, thereby improving the processing quality.
[0004] This utility model discloses a sealing device for filling bagged milk, comprising a frame, two rollers, a chain drive belt, a conveyor motor, a placement component, a clamping component, a sealing component, a detection component, and a support component. The bottom of the frame is mounted on the support component. Rollers are installed at both ends of the frame, and a chain drive belt is installed between the two rollers. The input end of the rollers is connected to the output end of the conveyor motor. The placement component is installed on the outer surface of the chain drive belt. The sealing component is installed on the outer wall at both ends of the middle of the frame. A clamping component is installed on the left side of the sealing component, and a detection component is installed on the right side of the sealing component. After the packaging bag is placed on the placement component and filling is completed, the chain drive belt drives the packaging bag to move to the right. After passing through the clamping component, the upper opening of the packaging bag is pre-treated by leveling. Then, the packaging bag passes through the sealing component to perform heat sealing on the plastic packaging bag. When the sealed packaging bag passes through the detection component, the sealing of the packaging bag is detected, so that it can be rejected in time if leakage occurs, thereby improving the processing quality.
[0005] Preferably, the placement assembly includes multiple conveyor platforms, multiple first slide rods, multiple sets of sliders, multiple trays, multiple sets of limiting clamps, and multiple springs. Multiple conveyor platforms are evenly installed on the outer surface of the chain drive belt. A sliding groove is opened inside each conveyor platform. The first slide rods are installed in the sliding grooves, and two sliders are symmetrically slidably installed in the sliding grooves, with the sliders slidably mounted on the outer wall of the first slide rods. Springs are installed at both ends of the sliders, and the springs are fitted onto the outer wall of the first slide rods. The trays are installed at the top center of the conveyor platform, and limiting clamps are installed on the top of the sliders. The packaging bag is placed in the tray, and the limiting clamps limit the front and rear sides of the packaging bag. After filling, the conveyor motor is started to drive the rotating wheel to rotate. The rotating wheel drives the chain drive belt to rotate, which in turn moves the packaging bag, thereby moving the packaging bag between multiple processes and improving work efficiency.
[0006] Preferably, the sealing assembly includes two fixed plates, a fixed frame, two support rods, two tightening sliders, two tightening springs, two uprights, two sealing frames, and two heat sealing rollers. The fixed plates are connected to the bottom of the fixed frame and are bolted to the middle of the outer wall of the frame. Rectangular slots are symmetrically opened at the top of the fixed frame, and the support rods are installed within these slots. The tightening sliders are slidably mounted on the outer wall of the support rods, and the tightening springs are fitted onto the outer wall of the support rods, with one end of the spring connected to the slider. Uprights are installed at the bottom of the sliders, and sealing frames are installed at the bottom of the uprights. The heat sealing rollers are rotatably mounted on the sealing frames. During operation, the heat sealing rollers are preheated to their operating temperature. When the chain drive belt moves the packaging bag between the two heat sealing rollers, the opening of the packaging bag is sealed. The tightening springs push the tightening sliders to slide on the support rods, ensuring tight contact between the two heat sealing rollers and improving sealing quality.
[0007] Preferably, the clamping assembly includes two first support rods, two mounting frames, two leveling rollers, and two guide arc plates. The two first support rods are symmetrically installed at the front and rear ends of the left side wall of the fixed frame by bolts. The mounting frame is installed at the end of the two first support rods that are close to each other. The leveling rollers are rotatably installed on the mounting frames. The guide arc plates are installed on the left side of the mounting frames. The front and rear guide arc plates are in the shape of a trumpet. When the chain drive belt drives the packaging bag through the two guide arc plates, it gathers the opening of the packaging bag towards the middle. At the same time, the opening of the packaging bag passes between the two leveling rollers, which level the opening of the packaging bag to ensure the subsequent sealing quality.
[0008] Preferably, the detection assembly includes two support arms, two slide rods, two telescopic arms, two telescopic springs, two detection frames, and two detection wheels. The two support arms are bolted to the front and rear ends of the right side wall of the fixed frame. Telescopic grooves are formed inside the support arms, and the slide rods are installed within these grooves. The telescopic arms are slidably mounted on the outer wall of the slide rods and within the telescopic grooves. The telescopic springs are fitted onto the outer wall of the slide rods, with one end connected to the telescopic arm. Detection frames are installed at the adjacent ends of the two telescopic arms, and detection wheels are rotatably mounted on the detection frames. When the sealed packaging bag passes between the two detection wheels, the detection frames and detection wheels push the limiting clamp to compress the packaging bag. The telescopic arms slide on the slide rods, compressing the telescopic springs. After the limiting clamp moves to the right side of the detection wheels, the spring pushes the slider to slide on the slide rod, allowing the limiting clamp to return to its original position. This avoids damage to the packaging bag, enabling non-destructive testing and facilitating timely rejection of leaked products.
[0009] Preferably, the support assembly includes two sets of support plates and a base. The two sets of support plates are installed at the bottom of the frame, and the support plates are installed at the top of the base. The support plates and the base support the bottom of the equipment, and the base increases the contact area with the ground to ensure stability during operation.
[0010] Preferably, the device also includes two sets of guide sliders and two limiting slide plates. Guide grooves are symmetrically provided on the left and right sides of the rectangular groove at the top of the fixing frame. Guide sliders are installed at both ends of the clamping slider, and the guide sliders are slidably installed in the guide grooves. Limiting guide grooves are provided at the upper and lower ends of the telescopic cavity of the slide rod. A limiting slide plate is installed at the end of the telescopic arm away from the detection frame, and the limiting slide plate is slidably installed in the limiting guide groove. When the clamping slider moves, it drives the guide sliders to slide in the guide grooves, thus limiting and guiding them. When the telescopic arm slides on the slide rod, it drives the limiting slide plate to slide in the limiting guide grooves, thus supporting and guiding it, increasing structural strength and ensuring stability.
[0011] Preferably, it also includes two sets of diagonal braces, with diagonal braces installed between the outer wall of the support plate and the bottom of the frame; the diagonal braces support the bottom of the frame, increasing the connection strength between the support plate and the frame and ensuring stability.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: After the packaging bag is placed on the placement component and filled, the chain drive belt drives the packaging bag to move to the right. After passing through the clamping component, the upper opening of the packaging bag is pre-treated by leveling. Then the packaging bag passes through the sealing component to heat seal the plastic packaging bag. When the sealed packaging bag passes through the detection component, the sealing of the packaging bag is detected, which facilitates timely rejection in case of leakage and improves the processing quality.

The conveyor table 5 has a sliding groove inside, and a first slide rod 6 is installed in the sliding groove. Two sliders 7 are symmetrically slidably installed in the sliding groove, and the sliders 7 are slidably installed on the outer wall of the first slide rod 6. Springs 10 are installed at the front and rear ends of the sliders 7, and the springs 10 are fitted on the outer wall of the first slide rod 6. A tray 8 is installed at the top center of the conveyor table 5, and a limit clamp 9 is installed on the top of the slider 7. A fixing plate 11 is connected to the bottom of the fixed frame 12. The fixing plate 11 is bolted to the middle of the outer wall of the frame 1. Rectangular slots are symmetrically opened at the top of the fixed frame 12. Support rods 17 are installed in the rectangular slots. A clamping slider 18 is slidably installed on the outer wall of the support rod 17. A clamping spring 19 is fitted on the outer wall of the support rod 17. One end of the clamping spring 19 is connected to the clamping slider 18. A vertical rod 20 is installed at the bottom of the clamping slider 18. A sealing frame 22 is installed at the bottom of the vertical rod 20. A heat sealing roller 23 is rotatably installed on the sealing frame 22. Two first support rods 13 are symmetrically installed at the front and rear ends of the left side wall of the fixed frame 12 by bolts. A mounting bracket 14 is installed at one end of the first support rod 13, close to each other. A leveling roller 15 is rotatably mounted on the mounting bracket 14. A guide arc plate 16 is installed on the left side of the mounting bracket 14. The two guide arc plates 16 are flared. Two support arms 24 are bolted to the front and rear ends of the right side wall of the fixed frame 12. A telescopic groove is opened in the support arm 24. A sliding rod 25 is installed in the telescopic groove. A telescopic arm 26 is slidably installed on the outer wall of the sliding rod 25 and in the telescopic groove. A telescopic spring 28 is fitted on the outer wall of the sliding rod 25. One end of the telescopic spring 28 is connected to the telescopic arm 26. A detection frame is installed at one end of the two telescopic arms 26, close to each other. 29. Detection wheels 30 are rotatably mounted on the detection frame 29. Two sets of support plates 31 are installed at the bottom of the frame 1 and at the top of the base 32. Guide grooves are symmetrically opened on the left and right sides of the rectangular groove at the top of the fixed frame 12. Guide sliders 21 are installed at the left and right ends of the top-tightening slider 18. The guide sliders 21 are slidably installed in the guide grooves. Limiting guide grooves are opened at the upper and lower ends of the telescopic cavity of the slide rod 25. Limiting slide plate 27 is installed at the end of the telescopic arm 26 away from the detection frame 29. The limiting slide plate 27 is slidably installed in the limiting guide groove. An inclined rod 33 is installed between the outer wall of the support plate 31 and the bottom of the frame 1. The packaging bag is placed in the tray 8, and the front and rear sides of the packaging bag are limited by the limiting clamps 9. After filling, the conveyor motor 4 is started to drive the rotating wheel 2 to rotate. The rotating wheel 2 drives the chain drive belt 3 to rotate, which can move the packaging bag, thereby moving the packaging bag between multiple processes and improving work efficiency. During operation, the heat sealing roller 23 is preheated to the operating temperature. When the chain drive belt 3 moves the packaging bag between the two heat sealing rollers 23, the opening of the packaging bag is sealed. The top spring 19 pushes the top slider 18 to slide on the support rod 17 to ensure close contact between the two heat sealing rollers 23 and improve the sealing quality. When the chain drive belt 3 moves the packaging bag between the two guide arc plates 16, the opening of the packaging bag is gathered towards the middle. At the same time, the opening of the packaging bag passes between the two leveling rollers 15 to level the opening of the packaging bag and ensure the subsequent sealing quality. When the sealed packaging bag passes between the two detection rollers 30, the detection frame 29 and the detection rollers 30 are pushed to the limit. The clamping plate 9 compresses the packaging bag, and the telescopic arm 26 slides on the slide bar 25 to compress the telescopic spring 28. After the limiting clamping plate 9 moves to the right side of the detection wheel 30, the spring 10 pushes the slider 7 to slide on the first slide bar 6, so that the limiting clamping plate 9 returns to its original position, which can avoid damage to the packaging bag, thus enabling non-destructive testing of the packaging bag. This facilitates timely rejection when leakage is detected. The bottom of the equipment is supported by the support plate 31 and the base 32. The base 32 increases the contact area with the ground to ensure stability during operation. When the pressing slider 18 moves, it drives the guide slider 21 to slide in the guide groove, which can limit and guide it. When the telescopic arm 26 slides on the slide bar 25, it drives the limiting slide plate 27 to slide in the limiting guide groove, which supports and guides it, increases the structural strength, and ensures stability. The bottom of the frame 1 is supported by the diagonal bar 33, which increases the connection strength between the support plate 31 and the frame 1 and ensures stability.
[0016] like Figures 1 to 5As shown, this utility model discloses a sealing device for filling bagged milk. During operation, the bottom of the device is supported by a support plate 31 and a base 32. The packaging bag is placed in a tray 8, and the front and rear sides of the packaging bag are limited by a limiting clamp 9. After filling, the conveyor motor 4 is started, driving the rotating wheel 2 to rotate. The rotating wheel 2 drives the chain drive belt 3 to rotate, which moves the packaging bag. When the chain drive belt 3 moves the packaging bag between two guide arc plates 16, the opening of the packaging bag is brought towards the center. At the same time, the opening of the packaging bag passes between two leveling rollers 15, which level the opening. During operation, the heat sealing roller 23 is preheated to the operating temperature. The chain drive belt 3 moves the packaging bag between two guide arc plates 16. When the two heat-sealing rollers 23 are in contact, the opening of the packaging bag is sealed. The top spring 19 pushes the top slider 18 to slide on the support rod 17 to ensure close contact between the two heat-sealing rollers 23. When the sealed packaging bag passes between the two detection wheels 30, the detection frame 29 and the detection wheels 30 push the limiting clamp 9 to squeeze the packaging bag. The telescopic arm 26 slides on the slide rod 25 to compress the telescopic spring 28. After the limiting clamp 9 moves to the right side of the detection wheel 30, the spring 10 pushes the slider 7 to slide on the first slide rod 6 to restore the limiting clamp 9 to its original position. This can avoid damage to the packaging bag, so as to perform non-destructive testing on the packaging bag and facilitate timely rejection when leakage is detected.
