Description

Technical Field

[0001] This invention relates to the field of filling production line technology, and more specifically, to a filling and sealing machine. Background Technology

[0002] Filling and sealing machines are widely used in product packaging in industries such as pharmaceuticals, daily chemicals, food, and chemicals. On the filling production line, before filling, the filling and sealing machine inevitably performs can feeding and stopping actions on the cans. If the cans suddenly stop while in transport, it can easily cause the following two situations: 1. The cans are squeezed, deformed, or scratched, resulting in damage to the can body and can cap, forming unqualified cans. The can qualification rate is low, and after filling, the filling accuracy and the qualification rate of the cap are low; 2. The cans jump or tip over, and the cans cannot enter the filling machine smoothly, resulting in low production efficiency. In addition, the cans are easy to roll into the filling machine and get stuck inside, resulting in a high can loss and scrap rate and high production costs.

[0003] In summary, how to provide a filling and sealing machine that can effectively protect the cans, thereby improving the can qualification rate, filling accuracy, and capping qualification rate, while also increasing production efficiency and saving production costs, is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a filling and sealing machine that can effectively protect cans, thereby improving the can qualification rate, filling accuracy, and capping qualification rate, while improving production efficiency and saving production costs.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A filling and sealing machine, comprising:

[0007] A pair of bottle conveyor chain side plates, forming a bottle conveyor chain channel between them, for conveying cans;

[0008] A buffer device includes a buffer plate and a first drive mechanism. The buffer plate is movably extended into the bottle conveying chain channel and is disposed opposite to another bottle conveying chain side plate. The fixed end of the first drive mechanism is connected to one of the bottle conveying chain side plates, and the drive end is connected to the buffer plate to drive the buffer plate to move relative to the other bottle conveying chain side plate.

[0009] A can-stopping device is located behind the buffer device. The can-stopping device includes a can-stopping assembly and a second drive mechanism. The can-stopping assembly is movable through the side plate of the bottle conveying chain and extends into the bottle conveying chain channel. The fixed end of the second drive mechanism is connected to the side plate of the bottle conveying chain, and the drive end is connected to the can-stopping assembly to drive the can-stopping assembly to extend into or out of the bottle conveying chain channel.

[0010] Preferably, the buffer device further includes a fixing member and a limiting member arranged parallel to each other. The first driving mechanism is perpendicular to the fixing member, and the fixing member is connected between the first driving mechanism and the bottle conveying chain side plate. One end of the limiting member is connected to the bottle conveying chain side plate, and the other end is provided with a limiting groove, with its groove opening facing the bottle conveying chain channel. One end of the buffer plate is connected to the driving end of the first driving mechanism, and the other end is movably inserted into the limiting groove.

[0011] Preferably, the limiting member includes a baffle and a U-shaped limiting block. One end of the baffle is connected to the side plate of the bottle conveying chain, and the other end has a notch that communicates with the interior of the limiting block to form the limiting groove.

[0012] Preferably, an adjustment pad is provided between the limiting member and the side plate of the bottle conveying chain.

[0013] Preferably, the can-stopping device further includes a mounting plate and a column assembly. The mounting plate is fixed to the side plate of the bottle conveying chain via the column assembly, and the driving end of the second driving mechanism passes through the mounting plate and is connected to the can-stopping assembly.

[0014] Preferably, the can-stopping assembly includes a U-shaped bent plate and a roller, the roller being rotatably disposed between the two side walls of the bent plate.

[0015] Preferably, a positioning rod is provided between the bending plate and the mounting plate.

[0016] Preferably, it further includes a control device, wherein a first solenoid valve assembly connected to the first drive mechanism is provided on the side plate of the bottle conveying chain and near the first drive mechanism, the first solenoid valve assembly being signal-connected to the control device, and / or a second solenoid valve assembly connected to the second drive mechanism is provided on the mounting plate, the second solenoid valve assembly being signal-connected to the control device.

[0017] Compared to the aforementioned background technology, the filling and sealing machine provided by the present invention has a buffer device and a can-stopping device, both of which are installed on the side plate of the bottle conveying chain. The buffer device is located in front of the can-stopping device. When it is necessary to stop the can in the bottle conveying chain channel, the first drive mechanism in the buffer device drives the buffer plate to move toward the opposite side plate of the bottle conveying chain to reduce the width of the bottle conveying chain channel and slow down the movement speed of the can. At the same time, the second drive mechanism in the can-stopping device drives the can-stopping component to pass through the side plate of the bottle conveying chain and extend into the bottle conveying chain channel to block the can in the bottle conveying chain channel, so that the decelerated can stops at the can-stopping component, thereby completing the can-stopping action.

[0018] In summary, this application uses a buffer device to first cushion the can, slowing its movement. Once the can has slowed, it moves to a stopping device, which then stops its movement, gradually bringing the can to a stop. This avoids the sudden stopping action in existing technologies, which can cause can deformation, scratches, jumping, or tipping. Therefore, this application effectively protects the can and ensures smooth can loading, improving the can's pass rate, thereby increasing filling accuracy and capping pass rate, while also improving production efficiency and saving production costs.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] The core of this invention is to provide a filling and sealing machine that can effectively protect cans, thereby improving the can qualification rate, filling accuracy, and capping qualification rate, while also increasing production efficiency and saving production costs.

[0031] It should be noted that in this embodiment, the orientation or positional relationship indicated by terms such as "upper" and "lower" is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] Please refer to Figure 1 This application provides a filling and sealing machine including a pair of bottle conveying chain side plates, a buffer device 3, and a can-stopping device 4; wherein, a bottle conveying chain channel is formed between the pair of bottle conveying chain side plates for conveying cans; the buffer device 3 includes a buffer plate 37 and a first drive mechanism 32, the buffer plate 37 is movably extended into the bottle conveying chain channel and is disposed opposite to the other bottle conveying chain side plate, the fixed end of the first drive mechanism 32 is connected to one bottle conveying chain side plate and the drive end is connected to the buffer plate 37 to drive the buffer plate 37 to move relative to the other bottle conveying chain side plate; the can-stopping device 4 is located behind the buffer device 3, the can-stopping device 4 includes a can-stopping assembly and a second drive mechanism 48, the can-stopping assembly is movably passed through the bottle conveying chain side plate and extended into the bottle conveying chain channel, the fixed end of the second drive mechanism 48 is connected to the bottle conveying chain side plate and the drive end is connected to the can-stopping assembly to drive the can-stopping assembly to extend into or out of the bottle conveying chain channel.

[0033] It should be noted that the two bottle conveyor chain side plates are arranged vertically and opposite to each other, that is, the upper bottle conveyor chain side plate 1 and the lower bottle conveyor chain side plate 2 form a bottle conveyor chain channel. When several cans enter the production line, they are all transported in the bottle conveyor chain channel.

[0034] The buffer device 3 is fixedly mounted on the lower bottle conveyor side plate 2. Specifically, the fixed end of the first drive mechanism 32 is fixedly connected to the lower bottle conveyor side plate 2, and the drive end is fixedly connected to the buffer plate 37. The buffer plate 37 is positioned opposite to the upper bottle conveyor side plate 1. A notch is provided on the lower bottle conveyor side plate 2 at a position corresponding to the buffer plate 37, allowing the first drive mechanism 32 to drive the buffer plate 37 through the lower bottle conveyor side plate 2, forming an adjustable bottle conveyor channel with the upper bottle conveyor side plate 1. This means that moving the buffer plate 37 towards the upper bottle conveyor side plate 1 reduces the width of the bottle conveyor channel; conversely, increasing the width of the bottle conveyor channel results in the first drive mechanism 32 performing the opposite operation. Alternatively, the buffer device 3 can also be fixed to the upper bottle conveyor side plate 1, as long as the buffer plate 37 can move relative to the lower bottle conveyor side plate 2 to adjust the width of the bottle conveyor channel.

[0035] The can-stopping device 4 is fixedly mounted on the upper bottle conveyor side plate 1 and located behind the buffer device 3. Specifically, the fixed end of the second drive mechanism 48 is fixedly connected to the upper bottle conveyor side plate 1, and the drive end is fixedly connected to the can-stopping assembly. A notch is provided on the upper bottle conveyor side plate 1 at a position corresponding to the can-stopping assembly, allowing the second drive mechanism 48 to drive the can-stopping assembly through the upper bottle conveyor side plate 1 and into the bottle conveyor channel to close the channel and prevent can movement. When the can-stopping action ends, the second drive mechanism 48 simply drives the can-stopping assembly upwards to extend out of the bottle conveyor channel. Alternatively, the can-stopping device 4 can also be fixedly mounted on the lower bottle conveyor side plate 2, as long as the can-stopping assembly can extend into and out of the bottle conveyor channel.

[0036] In use, when it is necessary to stop the can in the bottle conveying chain channel, the first drive mechanism 32 in the buffer device 3 drives the buffer plate 37 to move toward the upper bottle conveying chain side plate 1 to reduce the width of the bottle conveying chain channel and slow down the movement speed of the can. At the same time, the second drive mechanism 48 in the can-stopping device 4 drives the can-stopping component to pass through the upper bottle conveying chain side plate 1 and extend into the bottle conveying chain channel to block the can in the bottle conveying chain channel, so that the decelerated can stops at the can-stopping component, thereby completing the can-stopping action.

[0037] In summary, this application uses the buffer device 3 to first buffer the can, slowing down its movement. After deceleration, the can moves to the can-stopping device 4, where it then stops the can's movement, causing it to gradually come to a stop. This avoids the sudden stopping action in existing technologies, which can cause can deformation, scratches, jumping, or tipping. Therefore, this application effectively protects the can and ensures smooth can loading, improving the can's pass rate, thereby increasing filling accuracy and capping pass rate, while also improving production efficiency and saving production costs.

[0038] Please refer to Figure 2Based on the above embodiments, the buffer device 3 further includes a fixing member 31 and a limiting member arranged in parallel with each other. The first driving mechanism 32 is perpendicular to the fixing member 31, and the fixing member 31 is connected between the first driving mechanism 32 and the side plate of the bottle conveying chain. One end of the limiting member is connected to the side plate of the bottle conveying chain, and the other end is provided with a limiting groove, and its groove opening is set towards the bottle conveying chain channel. One end of the buffer plate 37 is connected to the driving end of the first driving mechanism 32, and the other end is movably inserted into the limiting groove.

[0039] Specifically, the fixing member 31 and the limiting member are parallel to each other and are distributed sequentially along the extension direction of the bottle conveying chain side plate. One end of the fixing member 31 is fixedly connected to the lower bottle conveying chain side plate 2, and the first driving mechanism 32 is vertically disposed at the other end of the fixing member 31. One end of the limiting member is fixedly connected to the lower bottle conveying chain side plate 2, and the other end is provided with a limiting groove, with the opening of the limiting groove facing the upper bottle conveying chain side plate 1. One end of the buffer plate 37 is provided with a connecting plate 33, and the driving end of the first driving mechanism 32 is fixedly connected to the connecting plate 33. The other end of the buffer plate 37 is inserted into the limiting groove and abuts against its side wall. The buffer plate 37 is then securely installed near the lower bottle conveyor side plate 2. In use, the first drive mechanism 32 drives the buffer plate 37 through the notch in the lower bottle conveyor side plate 2 and moves toward the upper bottle conveyor side plate 1. At this time, the other end of the buffer plate 37 disengages from the limiting groove, and the can moves along the bottle conveyor channel formed between the buffer plate 37 and the upper bottle conveyor side plate 1. The buffer plate 37 is compressed and deforms downward. The limiting groove can limit the deformation of the buffer plate 37 to prevent the buffer plate 37 from tilting too much and causing the can to shake, thereby ensuring the safe movement of the can.

[0040] Based on the above embodiments, the limiting component includes a baffle 34 and a U-shaped limiting block 35. One end of the baffle 34 is connected to the side plate of the bottle conveying chain, and the other end has a notch and communicates with the interior of the limiting block 35 to form a limiting groove.

[0041] Specifically, the limiting block 35 is fixed to one end of the baffle 34, and the other end of the baffle 34 is fixedly connected to the lower bottle conveying chain side plate 2. The limiting block 35 is arranged opposite to the first driving mechanism 32. The limiting block 35 has a U-shaped structure with a U-shaped hollow structure inside. There is a notch on the connecting rod and at the position corresponding to the limiting block 35. The notch and the U-shaped hollow structure form a limiting groove, so that the limiting groove has a certain thickness in the vertical direction. When in use, the first driving mechanism 32 drives the buffer plate 37 to pass through the notch of the lower bottle conveying chain side plate 2 and move towards the upper bottle conveying chain side plate 1 to the set position. At the same time, the other end of the buffer plate 37 moves from the bottom of the limiting groove to the opening of the groove. At this time, one end of the buffer plate 37 is fixedly connected to the first driving mechanism 32, and the other end is clamped through the opening of the limiting groove to prevent the buffer plate 37 from tilting and better ensure the smooth and stable movement of the can.

[0042] Optionally, an adjustment pad 36 is provided between the limiting member and the lower bottle conveying chain side plate 2 to reduce the gap between the two, thereby ensuring that the buffer plate 37 is stably installed on the lower bottle conveying chain side plate 2, and thus preventing the buffer plate 37 from shaking.

[0043] Please refer to Figure 3 Based on the above embodiments, the can-stopping device 4 also includes a mounting plate 46 and a column assembly 47. The mounting plate 46 is fixed to the side plate of the bottle conveying chain through the column assembly 47, and the driving end of the second driving mechanism 48 passes through the mounting plate 46 and is connected to the can-stopping assembly.

[0044] Specifically, to ensure that the can-stopping device 4 is securely installed on the upper bottle conveying chain side plate 1, several columns are connected between the mounting plate 46 and the upper bottle conveying chain side plate 1. The second drive mechanism 48 is vertically inserted through the fixing member 31, and its drive end is fixedly connected to the can-stopping assembly to smoothly drive the can-stopping assembly to extend into or out of the bottle conveying chain channel.

[0045] Based on the above embodiments, the can-stopping assembly includes a U-shaped bent plate 42 and a roller 44, with the roller 44 rotatably disposed between the two side walls of the bent plate 42.

[0046] Specifically, the open end of the bending plate 42 has a U-shaped structure, and a roller 43 is set between its two side walls. The roller 43 is fitted with a roller 44, and the driving end of the second driving mechanism 48 is connected to the closed end of the bending plate 42. In use, the second driving mechanism 48 drives the bending plate 42 to extend into the bottle conveying chain channel. When the can moves to the can-stopping device 4 after deceleration, the roller 44 slides in contact with the can to avoid scratching or squeezing the can, thereby ensuring the can qualification rate.

[0047] Based on the above embodiment, a positioning rod 45 is provided between the bending plate 42 and the mounting plate 46. Specifically, a round hole is provided on the mounting plate 46 at a position corresponding to the closed end of the bending plate 42. A bushing 49 is fitted inside the round hole. The positioning rod 45 passes through the bushing 49 and is fixedly connected to the bending plate 42 to restrict the rotation of the bending plate 42, so that the bending plate 42 only extends into or out of the bottle conveying chain channel vertically.

[0048] Based on the above embodiments, a first solenoid valve assembly connected to the first drive mechanism 32 is provided on the side plate 2 of the lower bottle conveying chain and near the first drive mechanism 32. The first solenoid valve assembly is signal-connected to the control device. And / or, a second solenoid valve assembly 41 connected to the second drive mechanism 48 is provided on the mounting plate 46. The second solenoid valve assembly 41 is signal-connected to the control device, so that the operator can remotely control the first drive mechanism 32 and the second drive mechanism 48 to realize the automated control of the filling and sealing machine's can-stopping action.

[0049] Optionally, both the first drive mechanism 32 and the second drive mechanism 48 adopt a single-cylinder double-acting cylinder with a simple structure and small space occupation, and both are equipped with speed regulating joints 5 at the air inlet and outlet to adjust the speed of the drive rod of the single-cylinder double-acting cylinder. In addition, the two drive mechanisms can also be selected from various structures such as hydraulic cylinders, electric cylinders, and motors.
