Description

Technical Field

[0001] This invention belongs to the field of bottle cap manufacturing technology, and in particular relates to a multi-purpose packaging bottle cap pressing device. Background Technology

[0002] Canned food refers to food made by processing, blending, canning, sealing, and sterilizing qualified raw materials. It can be stored at room temperature for a long time and its flavor is preserved. Because of its sealed packaging and strict sterilization process, canned food can be stored for a long time without spoiling.

[0003] According to the search, patent document CN109016594A discloses a multi-purpose packaging bottle cap pressing device, including a working base and a support frame. The support frame is set on one side of the working base, and an mounting frame is installed on the top of the support frame. One side of the mounting frame extends vertically above one side of the working base. A servo motor and a finished product collection box are set at the bottom of the working base. The output shaft of the servo motor extends to the top side of the working base and is fixedly connected to a shifting plate. The plate of the shifting plate has a vertical through hole. A limiting mold is set in the vertical through hole. The limiting mold has a vertical placement through hole. The working base has a second vertical through hole. A servo motor is fixedly installed on one side of the mounting frame by screws. The output shaft of the servo motor is connected to a cam.

[0004] Existing pressing devices for bottle caps still have the following problems:

[0005] 1. Existing top-pressing devices for bottle caps mainly use vertically arranged spring groups to achieve the reciprocating springback of the device. However, after long-term use, the springs will have their elasticity greatly reduced due to excessive force and metal fatigue, thus causing the device to malfunction.

[0006] 2. Existing pressing devices for bottle caps can only press one cap at a time, resulting in low efficiency. They are not suitable for large-scale production activities, increase the production cost of bottle caps, and fail to meet people's needs in production and daily life.

[0007] 3. Existing cap-pressing devices cannot remove dust from bottle caps during the cap-pressing process. When the cap edges curl, dust and dirt can easily get trapped inside, which makes it difficult to preserve and use canned food later.

[0008] 4. The existing top-pressing device for bottle cap packaging does not have an automatic feeding mechanism. Unprocessed bottle caps need to be manually filled. The overall automation level of the device is low, and a certain amount of human resources is still required, which is not conducive to the device's control over production costs and demand.

Detailed Implementation

[0031] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0032] like Figures 1-6 As shown, a multi-purpose packaging bottle cap pressing device includes:

[0033] A base plate 1 is fixedly connected to two vertical connecting plates 2. A circular pressing buckle 3 is fixedly connected to the vertical connecting plates 2. Two connecting plates 4 are fixedly connected to the vertical connecting plates 2. A fixing plate 5 is fixedly connected to one end of the two connecting plates 4 away from the vertical connecting plates 2. A bottle cap storage shell 6 is provided on the fixing plate 5. Openings are provided at the top and bottom of the bottle cap storage shell 6.

[0034] A servo motor 7 is fixedly connected to the base plate 1, a drive mechanism is provided on the base plate 1, a support plate 8 is fixedly connected to the base plate 1, and a pressing mechanism, a dust removal mechanism and a material discharge mechanism are provided on the support plate 8.

[0035] The drive mechanism includes a rotating support frame 9 fixedly connected to the base plate 1. A drive rotating disk 10 is rotatably connected to the rotating support frame 9. A second pulley 11 is coaxially fixedly connected to the drive rotating disk 10. A first pulley 12 is coaxially fixedly connected to the output end of the servo motor 7. A transmission belt is sleeved between the first pulley 12 and the second pulley 11. A snap-fit ​​shaft is fixedly connected to the drive rotating disk 10 away from the axis. When the servo motor 7 is working normally, the first pulley 12 coaxially fixedly connected to the output end of the servo motor 7 can rotate. Through the transmission of the transmission belt, the second pulley 11 connected to it can rotate, thereby causing the drive rotating disk 10 to rotate.

[0036] The pressing mechanism includes a pair of matching brackets 13 fixedly connected to the receiving plate 8. A main crossbar 14 is fixedly connected to each of the two matching brackets 13. Sliding rods 15 are fixedly connected to both ends of the main crossbar 14. A sliding ring 16 is slidably connected to each sliding rod 15. A return spring 17 is sleeved on each sliding rod 15 and fixedly connected to the sliding ring 16. A U-shaped partition 18 is fixedly connected to the receiving plate 8. A vertical support sliding rod 19 is fixedly connected to the U-shaped partition 18. A sliding sleeve 20 is slidably connected to the vertical support sliding rod 19. The sliding sleeve 20 is close to the rotating drive. A connecting shaft 21 is fixedly connected to one end of the rotating disk 10. A loop yoke 22 is fixedly connected to the connecting shaft 21. The loop yoke 22 matches the snap-fit ​​shaft, and the snap-fit ​​shaft is slidably connected within the loop yoke 22. Two pairs of drive shafts 23 are rotatably connected to the sliding sleeve 20. Each pair of drive shafts 23 is rotatably connected to a sliding ring 16 on the corresponding side. Two connecting rods 24 are fixedly connected to the ends of the sliding rings 16 that are away from each other. A top-pressing plate 25 is fixedly connected to the ends of the two connecting rods 24 that are away from the sliding rings 16. The top-pressing plate 25 is positioned corresponding to the bottle cap storage shell 6. When the drive rotating disk 10 rotates, the snap-fit ​​shaft on the drive rotating disk 10 drives the snap-fit ​​yoke 22 to reciprocate up and down. The connecting shaft 21 and the sliding sleeve 20, which are fixedly connected to the sliding sleeve 22, will reciprocate on the vertical support slide rod 19. The reciprocating motion of the sliding sleeve 20 will cause the two pairs of drive shafts 23 rotatably connected to it to rotate, so that the sliding ring 16 at the end of the drive shaft 23 away from the sliding sleeve 20 can reciprocate on the sliding rod 15. The return spring 17 can make the sliding ring 16 return to the initial position with less effort, so as to reduce the installation cost. The driving force cost of the device is reduced, and when the sliding ring 16 moves, the top pressing plate 25 connected by the connecting rod 24 will also move accordingly, thereby extruding and molding the bottle cap. By setting up a pressure-blocking mechanism, the pressure is distributed by two horizontally arranged springs, which not only reduces the pressure on the springs and extends their service life, but also makes spring replacement and maintenance more convenient. Two bottle caps can be extruded and molded at the same time, thereby further improving the working efficiency of the device compared with traditional equipment, and thus making the production efficiency of the device higher.

[0037] The dust removal mechanism includes a top-pressure shaft 26 fixedly connected to the top-pressure forming plate 25. The sliding rod 15 is hollow and airtight. A piston plate 27 is slidably connected inside the sliding rod 15. The piston plate 27 is fixedly connected to the top-pressure shaft 26 on the corresponding side. A flexible hose is connected to the ends of the two sliding rods 15 that are far apart from each other. A dust removal port 28 is provided on the top-pressure forming plate 25. The flexible hose is connected to the dust removal port 28. When the sliding ring 16 moves on the sliding rod 15, the top-pressure shaft 26 will drive the piston plate 27 to move accordingly. The piston plate 27 will compress the air inside the sliding rod 15 and spray gas through the flexible hose to the dust removal port 28, thereby removing dust from the bottle cap. By setting up the dust removal mechanism, the bottle cap can also be dusted simultaneously during the extrusion forming process. This prevents dust from entering the rolled edge of the bottle cap during the extrusion forming process, which would cause inconvenience in subsequent use of the bottle cap.

[0038] The discharge mechanism includes a discharge housing 29 connected to the top opening of the bottle cap storage housing 6. A pneumatic piston 30 is slidably connected inside the discharge housing 29. Several receiving shafts 31 are fixedly connected to the sliding sleeve 20. A pressure cylinder 32 is fixedly connected to the vertical support slide rod 19. A pressure slidable plate is slidably connected inside the pressure cylinder 32. Several receiving shafts 31 are fixedly connected to the pressure slidable plate. A one-way valve is connected to the top of the pressure cylinder 32. Two connecting pipes are connected to the top of the pressure cylinder 32, and the two connecting pipes are respectively connected to two discharge housings 29. When the sliding sleeve 20 moves on the vertical support slide rod 19, the fixedly connected... Several receiving shafts 31 drive the pressure slider to continuously compress air inside the pressure cylinder 32. The air enters the discharge shell 29 through the connecting pipe, pushing the pneumatic piston 30 to move, thereby pushing the material inside the discharge shell 29, thus realizing the function of automatic discharge and feeding. The flow direction of the one-way valve installed on the pressure cylinder 32 is from the outside of the pressure cylinder 32 to the inside of the pressure cylinder 32. By setting up a discharge mechanism, unprocessed bottle caps can be automatically discharged, which greatly improves the automation level of the device, reduces the labor cost of the device when processing bottle caps, and indirectly improves the production efficiency of the device.

[0039] The working principle of this invention is as follows:

[0040] When the servo motor 7 is working normally, the first pulley 12, which is coaxially fixedly connected to the output end of the servo motor 7, can rotate. Through the transmission of the transmission belt, the second pulley 11 connected to it can rotate, thereby causing the drive rotating disk 10 to rotate.

[0041] When the drive turntable 10 rotates, the snap-fit ​​shaft on the drive turntable 10 will drive the snap-fit ​​yoke 22 to reciprocate up and down. The connecting shaft 21 and the sliding sleeve 20 fixedly connected to the sliding sleeve 22 will reciprocate on the vertical support slide rod 19. The reciprocating motion of the sliding sleeve 20 will cause the two pairs of drive shafts 23 rotatably connected to it to rotate, so that the sliding ring 16 at the end of the drive shaft 23 away from the sliding sleeve 20 can reciprocate on the sliding rod 15. The return spring 17 can make the sliding ring 16 return to the initial position with less effort, so as to reduce the driving force cost of the device. When the sliding ring 16 moves, the top pressing plate 25 connected through the connecting rod 24 will also move accordingly, thereby extruding and molding the bottle cap. By setting up the pressure-reducing mechanism and the two horizontally set springs to distribute the pressure, not only is the pressure on the spring reduced and the spring service life extended, but the spring replacement and maintenance are also more convenient. Two bottle caps can be extruded and molded at the same time, thereby further improving the working efficiency of the device compared with traditional equipment, thus making the production efficiency of the device higher.

[0042] When the sliding ring 16 moves on the sliding rod 15, the top pressure shaft 26 will drive the piston plate 27 to move accordingly. The piston plate 27 will compress the air inside the sliding rod 15 and spray the gas through the dust removal port 28 through the hose, thereby removing dust from the bottle cap. By setting up the dust removal mechanism, the bottle cap can also be dusted simultaneously during the extrusion molding process. This prevents dust from entering the rolled edge when the bottle cap is being extruded, thus avoiding inconvenience in subsequent use.

[0043] When the sliding sleeve 20 moves on the vertical support slide rod 19, the several receiving shafts 31 fixedly connected to the sliding sleeve 20 will drive the pressure slider to continuously compress the air in the pressure cylinder 32. The air enters the discharge shell 29 through the connecting pipe, pushing the pneumatic piston 30 to move, thereby pushing the material in the discharge shell 29, thus realizing the function of automatic discharge and feeding. The flow direction of the one-way valve installed on the pressure cylinder 32 is from the outside of the pressure cylinder 32 to the inside of the pressure cylinder 32. By setting up the discharge mechanism, the unprocessed bottle caps can be automatically discharged, which greatly improves the automation level of the device, reduces the labor cost of the device when processing bottle caps, and indirectly improves the production efficiency of the device.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
