Description

Technical Field

[0001] This utility model belongs to the field of canning technology, and in particular relates to a sealing device for canning. Background Technology

[0002] Canning is a crucial step in food canning. Using automated or semi-automated equipment, sterilized food is filled into clean, sterilized metal cans (such as tin cans) or glass jars, and then pre-formed lids are quickly placed on top, followed by a tight seal under vacuum or pressure. This process typically includes edge-sealing (double edge-sealing), vacuuming, heat sealing, or laser welding to ensure a good sealing environment inside the can, preventing microbial invasion and oxidation of the contents, thereby extending the shelf life and preserving the flavor and nutrients of the food. The quality of the sealing directly affects the storage safety and shelf life of the canned goods; therefore, strict control of sealing pressure, temperature, and seal integrity is essential.

[0003] For example, Chinese Patent Publication No. CN215287909U discloses a sealing device for can manufacturing and processing, relating to the field of can processing technology. This sealing device includes a base plate, on the top of which are welded and mounted two sets of vertical plates and two sets of working plates. Rollers are rotatably mounted on the front outer walls of both sets of working plates. A second motor is fixedly mounted on the rear outer wall of each working plate. The output shaft of the second motor passes through the working plate via a coupling and is welded and mounted to the rollers. Conveyor belts are installed on the two sets of rollers, and the two sets of rollers are connected by a transmission belt. Support plates are welded and mounted on the top of the two sets of vertical plates, and a working box is welded and mounted on the top of the support plates. Transport holes are opened on both sides of the working box, and the conveyor belt passes through the transport holes in the working box. This invention can provide some protection for cans during transport and can also assist in sealing cans of different sizes.

[0004] The aforementioned patent has the following problems: in actual use, it does not have the function of positioning and fixing the cans to be sealed, which easily leads to the lid deviating from the can when sealing the cans, resulting in the inability to seal them, which is not conducive to the use of workers. In view of this, we propose a sealing device for can processing. Utility Model Content

[0005] The purpose of this invention is to provide a sealing device for canning, so as to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a sealing device for can processing, including a base and a conveyor belt. The conveyor belt is disposed on one side of the base. A connecting plate is fixedly connected to one side of the base. A first motor is fixedly installed on the top of the connecting plate. A connecting plate is fixedly connected to the output end of the first motor. A hydraulic lifting rod is fixedly installed on the top of the connecting plate. A mounting plate is fixedly connected to the output end of the hydraulic lifting rod. Two symmetrically distributed second motors are fixedly installed on the top of the mounting plate. The output shafts of the two second motors extend to the bottom of the mounting plate. Suction cups are fixedly connected to the output shafts of the two second motors. The third motor has an output shaft that extends through to the top of the base. A turntable is slidably mounted on the top of the base. The output shaft of the third motor is fixedly connected to the turntable. Four housings are fixedly connected to the top of the turntable. A fixing plate is fixedly connected inside each of the four housings. A rotating shaft is rotatably mounted on the bottom of each of the four fixing plates. The bottom of each of the four rotating shafts is rotatably mounted on the bottom of the inner wall of the housing. Four clamping blocks are provided on the top of each of the four fixing plates. Four sets of rotating components are respectively installed inside the four housings and are used to drive the four rotating shafts to rotate. Four sets of moving components are respectively disposed inside the four housings and are used to drive the corresponding four clamping blocks to move.

[0007] In this technical solution, rotating the handle causes the worm gear to rotate, which in turn rotates the worm wheel and the shaft. The first bevel gear drives four second bevel gears to rotate, which in turn drives the threaded rod to rotate. The threaded sleeve slides along the groove, pushing the slider and clamping block to move towards the center and clamping the can. By activating the hydraulic lifting rod, the output end of the hydraulic lifting rod drives the mounting plate, the second motor, and the suction cup to descend. At this time, the lid below the suction cup will come into contact with the can. By activating the second motor, the output end of the second motor drives the suction cup and the lid to rotate, thus completing the capping operation. With the above structure, the can capping operation can be completed. This device fixes the can in the center of the fixing plate before capping, avoiding errors during the capping process.

[0008] By activating the third motor, the output of the third motor drives the turntable to rotate, causing the four housings on top to rotate sequentially to the position below one of the suction cups. After the first motor starts, it drives the connecting plate to rotate horizontally, causing the hydraulic lifting rod and mounting plate on top to move synchronously, bringing the two second motors at the bottom of the mounting plate and their connected suction cups closer to the can lids on the conveyor belt. The hydraulic lifting rod extends and retracts to adjust the height of the suction cups until they contact the can lids. The second motor drives the suction cups to rotate, adsorb the can lids, and adjust their angles, completing the adsorption and position adjustment of the can lids. At this point, the cans inside the next housing can be sealed. This device has a high degree of automation and can automatically complete the can lid loading operation in a short time, reducing unnecessary workload for workers and making it more convenient for them to use.

[0009] In the above technical solution, a support frame is fixedly connected to the bottom of the base, and the third motor is fixedly mounted on the support frame.

[0010] In this technical solution, the support frame ensures that the third motor will not idle during operation.

[0011] In the above technical solution, the rotating component further includes a worm gear, which is fixedly sleeved on the outside of the rotating shaft. The same worm is rotatably installed on both sides of the inner wall of the housing, and the worm and the worm gear are meshed together.

[0012] In this technical solution, since the worm and worm wheel are meshed together, the rotation of the worm can drive the rotation of the worm wheel.

[0013] In the above technical solution, a handle is rotatably mounted on one side of the housing, and the handle is fixedly connected to the worm gear.

[0014] In this technical solution, the worm gear can be rotated by the handle.

[0015] In the above technical solution, the moving component further includes four threaded rods, which are rotatably installed around the inner wall of the housing. Each of the four threaded rods is threadedly connected to a threaded sleeve, and each of the four threaded sleeves is fixedly connected to a slider on its top. Four clamping blocks are fixedly connected to one side of each of the four sliders.

[0016] In this technical solution, the slider and clamp can be moved by rotating the threaded rod.

[0017] In the above technical solution, the top of the fixing plate is provided with four circumferentially distributed sliding grooves, and the four sliders are respectively slidably installed inside the four sliding grooves.

[0018] In this technical solution, the threaded sleeve is prevented from rotating when it moves by sliding the slider inside the groove.

[0019] In the above technical solution, further, one end of each of the four threaded rods is fixedly connected to a second bevel gear, and a first bevel gear is fixedly sleeved on the outside of the rotating shaft, with the four second bevel gears meshing with the first bevel gear.

[0020] In this technical solution, since the four second bevel gears are meshed with the first bevel gear, the rotation of the first bevel gear can drive the four second bevel gears to rotate simultaneously.

[0021] The beneficial effects of this utility model are: 1. By rotating the handle, the worm gear rotates, and the worm wheel and shaft rotate. The first bevel gear drives four second bevel gears to rotate, which in turn drives the threaded rod to rotate. The threaded sleeve slides along the groove, pushing the slider and clamping block to move towards the center and clamping the can. By activating the hydraulic lifting rod, the output end of the hydraulic lifting rod drives the mounting plate, the second motor, and the suction cup to descend. At this time, the lid below the suction cup will contact the can. By activating the second motor, the output end of the second motor drives the suction cup and the lid to rotate, thus completing the capping operation. With the above structure, the can capping operation can be completed. This device fixes the can in the center of the fixing plate before capping, avoiding errors during the capping process.

[0022] 2. By starting the third motor, the output of the third motor drives the turntable to rotate, causing the four housings on the top to rotate sequentially to below one of the suction cups. After the first motor starts, it drives the connecting plate to rotate horizontally, causing the hydraulic lifting rod and mounting plate on the top to move synchronously, so that the two second motors at the bottom of the mounting plate and their connected suction cups approach the can lids on the conveyor belt. The hydraulic lifting rod extends and retracts to adjust the height of the suction cups until they contact the can lids. The second motor drives the suction cups to rotate to adsorb the can lids and adjust their angles, completing the adsorption and position adjustment of the can lids. At this time, the cans inside the next housing can be sealed. This device has a high degree of automation and can automatically complete the loading of can lids in a short time, reducing unnecessary workload for workers and making it more convenient for workers to use.

These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0027] Example 1: This example provides a canning capping device, including a base 1 and a conveyor belt 8. The conveyor belt 8 is disposed on one side of the base 1. A connecting plate 2 is fixedly connected to one side of the base 1. A first motor 3 is fixedly installed on the top of the connecting plate 2. A connecting plate 4 is fixedly connected to the output end of the first motor 3. A hydraulic lifting rod 5 is fixedly installed on the top of the connecting plate 4. A mounting plate 9 is fixedly connected to the output end of the hydraulic lifting rod 5. Two symmetrically distributed second motors 6 are fixedly installed on the top of the mounting plate 9. The output shafts of the two second motors 6 extend through to the bottom of the mounting plate 9. Suction cups 7 are fixedly connected to the output shafts of the two second motors 6. The third motor 11 has its output shaft extending through to the top of the base 1. A turntable 12 is slidably mounted on the top of the base 1. The output shaft of the third motor 11 is fixedly connected to the turntable 12. Four housings 13 are fixedly connected to the top of the turntable 12. A fixing plate 14 is fixedly connected inside each of the four housings 13. A rotating shaft 17 is rotatably mounted on the bottom of each of the four fixing plates 14. The bottom of each of the four rotating shafts 17 is rotatably mounted on the bottom of the inner wall of the housing 13. Four clamping blocks 25 are provided on the top of each of the four fixing plates 14. Four sets of rotating components are respectively installed inside the four housings 13 and are used to drive the four rotating shafts 17 to rotate. Four sets of moving components are respectively installed inside the four housings 13 and are used to drive the corresponding four clamping blocks 25 to move.

[0028] In this system, rotating the handle 16 causes the worm gear 15 to rotate, and the worm wheel 18 and the rotating shaft 17 to rotate. The first bevel gear 20 drives the four second bevel gears 21 to rotate, which in turn drives the threaded rod 19 to rotate. The threaded sleeve 22 slides along the slide groove 24, pushing the slider 23 and the clamping block 25 to move towards the center and clamp the can. By activating the hydraulic lifting rod 5, the output end of the hydraulic lifting rod 5 drives the mounting plate 9, the second motor 6, and the suction cup 7 to descend. At this time, the lid below the suction cup 7 will come into contact with the can. By activating the second motor 6, the output end of the second motor 6 drives the suction cup 7 and the lid to rotate, thus completing the sealing operation. With the above structure, the sealing operation of the can can be completed. Before sealing, this device fixes the can in the center position of the fixing plate 14, avoiding errors during the sealing process.

[0029] By starting the third motor 11, the output of the third motor 11 drives the turntable 12 to rotate, causing the four housings 13 on the top to rotate sequentially to the underside of one of the suction cups 7. After the first motor 3 starts, it drives the connecting plate 4 to rotate horizontally, causing the hydraulic lifting rod 5 and the mounting plate 9 on the top to move synchronously, so that the two second motors 6 at the bottom of the mounting plate 9 and the suction cups 7 connected to them approach the can lids on the conveyor belt 8. The hydraulic lifting rod 5 extends and retracts to adjust the height of the suction cups 7 until they contact the can lids. The second motor 6 drives the suction cups 7 to rotate to adsorb the can lids and adjust their angles, completing the adsorption and position adjustment of the can lids. At this time, the cans inside the next housing 13 can be sealed. This device has a high degree of automation and can automatically complete the loading operation of can lids in a short time, reducing the unnecessary workload of the staff and making it more convenient for the staff to use.

[0030] Example 2: This example provides a sealing device for canning. In addition to the technical solutions of the above examples, it also has the following technical features: a support frame 10 is fixedly connected to the bottom of the base 1, and a third motor 11 is fixedly installed on the support frame 10.

[0031] The support frame 10 ensures that the third motor 11 will not idle during operation.

[0032] Example 3: This example provides a sealing device for canning. In addition to the technical solutions of the above examples, it also has the following technical features: the rotating component includes a worm gear 18, which is fixedly sleeved on the outside of the rotating shaft 17. The same worm 15 is rotatably installed on both sides of the inner wall of the housing 13, and the worm 15 and the worm gear 18 are meshed together.

[0033] Since the worm 15 and the worm wheel 18 are meshed together, the rotation of the worm 15 can drive the worm wheel 18 to rotate.

[0034] Example 4: This example provides a sealing device for canning. In addition to the technical solutions of the above examples, it also has the following technical features: a handle 16 is rotatably mounted on one side of the housing 13, and the handle 16 is fixedly connected to the worm gear 15.

[0035] The worm gear 15 can be rotated by the handle 16.

[0036] Example 5: This example provides a sealing device for canning. In addition to the technical solutions of the above examples, it also has the following technical features: the moving component includes four threaded rods 19, which are rotatably installed around the inner wall of the housing 13. Each of the four threaded rods 19 is threadedly connected to a threaded sleeve 22. Each of the four threaded sleeves 22 is fixedly connected to a slider 23 on its top. Each of the four clamping blocks 25 is fixedly connected to one side of the four sliders 23.

[0037] The rotation of the threaded rod 19 can drive the slider 23 and the clamping block 25 to move.

[0038] Example 6: This example provides a sealing device for canning. In addition to the technical solutions of the above examples, it also has the following technical features: the top of the fixing plate 14 is provided with four circumferentially distributed sliding grooves 24, and four sliders 23 are respectively slidably installed inside the four sliding grooves 24.

[0039] The slider 23 is slidably installed inside the groove 24, so that the threaded sleeve 22 will not rotate when it moves.

[0040] Example 7: This example provides a sealing device for canning. In addition to the technical solutions of the above examples, it also has the following technical features: one end of each of the four threaded rods 19 is fixedly connected to a second bevel gear 21, the outside of the rotating shaft 17 is fixedly sleeved with a first bevel gear 20, and the four second bevel gears 21 are meshed with the first bevel gear 20.

[0041] Since the four second bevel gears 21 are meshed with the first bevel gear 20, the rotation of the first bevel gear 20 can drive the four second bevel gears 21 to rotate simultaneously.

[0042] Working principle: By rotating the handle 16, the handle 16 drives the worm gear 15 to rotate. Since the worm gear 15 meshes with the worm wheel 18, the rotation of the worm gear 15 drives the worm wheel 18 and the rotating shaft 17 to rotate. At the same time, the first bevel gear 20 on the rotating shaft 17 drives the four second bevel gears 21 to rotate, which drives the threaded rod 19 to rotate. The threaded sleeve 22 slides along the slide groove 24 as the threaded rod 19 rotates, pushing the slider 23 and the clamping block 25 to move towards the center and clamp the can. Rotating the handle 16 in the opposite direction will cause the clamping block 25 to move. Moving away from the can, the hydraulic lifting rod 5 is activated. The output end of the hydraulic lifting rod 5 then drives the mounting plate 9, the second motor 6, and the suction cup 7 to descend. At this time, the lid below the suction cup 7 will come into contact with the can. By activating the second motor 6, the output end of the second motor 6 drives the suction cup 7 and the lid to rotate, thus completing the sealing operation. With the above structure, the can sealing operation can be completed. This device fixes the can in the center position of the fixing plate 14 before sealing, avoiding errors during the sealing process.

[0043] By starting the third motor 11, the output of the third motor 11 drives the turntable 12 to rotate, causing the four housings 13 on the top to rotate sequentially to the underside of one of the suction cups 7. After the first motor 3 starts, it drives the connecting plate 4 to rotate horizontally, causing the hydraulic lifting rod 5 and the mounting plate 9 on the top to move synchronously, so that the two second motors 6 at the bottom of the mounting plate 9 and the suction cups 7 connected to them approach the can lids on the conveyor belt 8. The hydraulic lifting rod 5 extends and retracts to adjust the height of the suction cups 7 until they contact the can lids. The second motor 6 drives the suction cups 7 to rotate to adsorb the can lids and adjust their angles, completing the adsorption and position adjustment of the can lids. At this time, the cans inside the next housing 13 can be sealed. This device has a high degree of automation and can automatically complete the loading operation of can lids in a short time, reducing the unnecessary workload of the staff and making it more convenient for the staff to use.
