Description

Technical Field

[0001] This application relates to the technical field of barrel packaging, and in particular to a packaging device for paint barrels. Background Technology

[0002] Paint is an engineering material that is applied to the surface of an object and, after drying, forms a tough protective film. It is widely used in construction, industry, and home furnishing. To meet the requirements of transportation, construction, and performance, paint is usually stored in paint containers.

[0003] Currently, common paint buckets are divided into two types: metal buckets and plastic buckets. Metal buckets have higher production costs and are prone to deformation during impacts, making plastic buckets the most commonly used. After paint is filled into plastic buckets, the lids need to be press-fitted to the bucket body to achieve a seal. However, existing sealing equipment requires manual placement of the lids on top of the bucket, increasing labor costs in the paint bucket sealing process. Utility Model Content

[0004] In order to reduce the labor costs in the process of sealing paint buckets, this application provides a paint bucket sealing device.

[0005] The paint bucket sealing device provided in this application adopts the following technical solution: A paint bucket sealing device includes a frame and a sealing assembly disposed on the frame. The frame has a sealing position and a loading position located on the side of the sealing position. The sealing assembly includes a pressing and gripping structure and a driving structure. The driving structure is used to drive the pressing and gripping structure to move between the sealing position and the loading position. The pressing and gripping structure can grip the bucket lid located at the loading position and can drive the bucket lid to the sealing position under the action of the driving structure and apply downward pressure to the bucket lid.

[0006] By adopting the above technical solution, when using the paint bucket sealing device of this application, the stacked bucket lids are placed in the loading position, and then the bucket body is placed in the sealing position. The driving structure drives the pressing and gripping structure to move to the loading position. Then, the pressing and gripping structure grips the bucket lid located in the loading position. Then, the driving structure drives the pressing and gripping structure in the opposite direction, so that the pressing and gripping structure moves the gripped bucket lid to the sealing position. Finally, the bucket lid is located directly above the bucket body. Then, the pressing and gripping structure applies downward pressure to the bucket lid, so that the bucket lid moves downward under the action of the pressing and gripping structure, and the pressing and gripping structure applies downward pressure to the bucket lid to press the bucket lid onto the bucket body, thereby completing the sealing of the paint bucket.

[0007] When using the paint bucket sealing device in the application to seal paint buckets, the need for manual installation of the lid onto the bucket body is avoided, thus reducing the labor cost of sealing paint buckets and improving the sealing efficiency.

[0008] Optionally, the pressing and gripping structure includes a moving seat, a power component disposed on the moving seat, a pressing plate disposed on the power component, and a negative pressure pipe passing through the moving seat. The moving seat is slidably connected to the frame and can move between the packaging position and the loading position. The power component is used to drive the pressing plate to move so that the pressing plate applies downward pressure to the barrel lid. The pressing plate is provided with a negative pressure chamber with the opening facing downward, and the negative pressure pipe is connected to the negative pressure chamber.

[0009] By adopting the above technical solution, when using the paint bucket sealing device of this application, the negative pressure pipe is first connected to the external negative pressure equipment; when gripping the bucket lid, the drive structure drives the moving seat, which then moves the moving seat from the sealing position toward the loading position, so that the pressing plate moves to the loading position. Then, the power component drives the pressing plate, which then moves toward the direction of the bucket lid located at the loading position, so that the pressing plate abuts against the bucket lid. Then, the external negative pressure equipment evacuates the negative pressure pipe to create negative pressure. A vacuum is created in the cavity, causing the lid to adhere to the pressure plate under negative pressure. Then, the power component drives the pressure plate upward, causing the lid to move upward. The drive structure then drives the motion seat to the sealing position. Once the motion seat reaches the sealing position, the lid is directly above the container. The power component then drives the pressure plate downward, causing the lid to move downward. Finally, the lid is pressed onto the container by the pressure plate and the power component, thus completing the sealing of the paint container.

[0010] Because the negative pressure pipe passes through the pressure plate, it can not only transport gas, but also guide the pressure plate, thereby increasing the stability of the pressure plate.

[0011] Optionally, the pressing plate is provided with a negative pressure channel inside, the negative pressure cavity is provided with a suction cup communicating with the negative pressure channel, and the negative pressure tube is connected to the negative pressure channel.

[0012] By adopting the above technical solution, after the pressing plate comes into contact with the bucket lid, the suction cup comes into contact with the bucket lid, and then the external negative pressure device evacuates the air, thereby causing the gas in the suction cup, the connecting channel and the negative pressure pipe to be drawn away by the external negative pressure device, so that the suction cup is attached to the bucket lid to achieve the gripping of the bucket lid. After the bucket lid is pressed onto the bucket body, the external negative pressure device vents the negative pressure pipe, and finally causes the suction cup to release its attachment to the bucket lid.

[0013] Optionally, the pressing plate is provided with a downward-facing receiving cavity, the cross-sectional shape of which is adapted to the bucket lid, and the negative pressure cavity is located at the center of the receiving cavity.

[0014] By adopting the above technical solution, since the pressing plate is provided with a downward-facing receiving cavity, the cross-sectional shape of the receiving cavity is adapted to the barrel lid. When the pressing plate grips the barrel lid, the barrel lid can be inserted into the receiving cavity to achieve positioning of the barrel lid, thereby achieving the effect of precise pressing of the barrel lid. In addition, it also increases the contact area between the pressing plate and the barrel lid, thereby increasing the connection stability between the barrel lid and the pressing plate.

[0015] Optionally, the accommodating cavity has an annular groove corresponding to the ribs of the bucket lid, and the negative pressure channel has a connecting hole communicating with the annular groove.

[0016] By adopting the above technical solution, since the annular groove is set with the ribs corresponding to the bucket lid, and the negative pressure channel has a connecting hole that communicates with the annular groove, the position of the annular groove can also adsorb the bucket lid when the bucket lid is gripped, thereby increasing the gripping stability of the bucket lid.

[0017] Optionally, at least two negative pressure pipes are provided at intervals and are located on both sides of the power component, the press plate is provided with an air connector communicating with the negative pressure channel, and the negative pressure pipe is threaded to the air connector.

[0018] By adopting the above technical solution, since at least two negative pressure pipes are arranged at intervals and located on both sides of the power component, the sliding fit points between the negative pressure pipe and the motion seat are increased, thereby further increasing the motion stability of the motion seat. At the same time, since the negative pressure pipe is threadedly connected to the air connector, the difficulty of assembling the negative pressure pipe and the pressure plate is reduced, thereby reducing the production difficulty of the paint bucket sealing device.

[0019] Optionally, the top of the frame has a support beam located at the bottom of the motion seat and a limiting beam located at the top of the motion seat. The support beam is provided with a guide rail, and the bottom of the motion seat is provided with a slider that slides with the guide rail.

[0020] By adopting the above technical solution, since the support beam is located at the bottom of the motion seat, it can support the motion seat and increase its stability; since the limiting beam is located at the top of the motion seat, it can limit the motion seat and prevent it from detaching from the support beam; and since the support beam is equipped with a guide rail, and the bottom of the motion seat is equipped with a slider that slides with the guide rail, the sliding cooperation between the slider and the guide rail can guide the movement of the motion seat and further increase its stability.

[0021] Optionally, the top of the motion seat is provided with a roller, the rotation axis of the roller is arranged perpendicular to the length direction of the guide rail, and the outer peripheral surface of the roller contacts the limiting beam.

[0022] By adopting the above technical solution, since the top of the motion seat is equipped with rollers, the rotation axis of the rollers is set perpendicular to the length direction of the guide rail, and the outer circumferential surface of the rollers contacts the limiting beam, the rollers and the limiting beam roll relative to each other when the motion seat moves. This ensures the limiting effect of the limiting beam on the motion seat on the one hand, and reduces the friction between the motion seat and the limiting beam on the other hand, thereby reducing the driving load of the drive structure.

[0023] Optionally, the paint bucket sealing device further includes a feeding assembly located at the feeding position. The feeding assembly includes a base, a storage bucket disposed above the base, a push plate disposed in the storage bucket, and an actuator disposed on the base for driving the push plate to move in the vertical direction.

[0024] By adopting the above technical solution, when placing the lids, multiple lids are placed in a storage container. As the lids are continuously gripped by the pressing and gripping structure, the actuator can push the push plate upward, causing the push plate to push the lids upward. This reduces the downward distance required for the pressing and gripping structure to grip the lids, thereby improving the sealing efficiency of the paint buckets.

[0025] Optionally, the paint bucket sealing device further includes a roller conveyor located at the sealing position, and the pressing and gripping structure is located above the roller conveyor.

[0026] By adopting the above technical solution, when sealing paint buckets, the buckets can be placed on a roller conveyor and then transported to the sealing position by the roller conveyor, thereby further realizing the automation level of pressing paint buckets. At the same time, the pressing and gripping structure can be used to grip the lid while the roller conveyor is transporting the bucket, thereby further improving the sealing efficiency of paint bucket lids.

[0027] In summary, this application includes at least one of the following beneficial technical effects: The paint bucket sealing device of this application includes a frame and a sealing component disposed on the frame. The frame has a sealing position and a loading position located on the side of the sealing position. The sealing component includes a pressing and gripping structure and a driving structure. The driving structure is used to drive the pressing and gripping structure to move between the sealing position and the loading position. The pressing and gripping structure can grip the lid located at the loading position and, under the action of the driving structure, can drive the lid to the sealing position and apply downward pressure to the lid. Therefore, when sealing paint buckets using the paint bucket sealing device of this application, the need for manual installation of the lid onto the bucket body is avoided, thus reducing the labor cost of sealing paint buckets and improving the sealing efficiency of paint buckets.

[0028] The pressing and gripping structure in this application includes a moving seat, a power component located on the moving seat, a pressing plate located on the power component, and a negative pressure pipe passing through the moving seat. The moving seat is slidably connected to the frame and can move between the sealing position and the loading position. The power component is used to drive the pressing plate to move so that the pressing plate applies downward pressure to the barrel lid. The pressing plate is provided with a negative pressure chamber with the opening facing downward. The negative pressure pipe is connected to the negative pressure chamber, thereby realizing the gripping of the barrel lid and increasing the stability of the pressing plate.

[0029] The pressing plate in this application has a negative pressure channel inside, and a suction cup connected to the negative pressure channel is installed in the negative pressure chamber. The negative pressure pipe is connected to the negative pressure channel. After the pressing plate is pressed against the bucket lid, the suction cup is pressed against the bucket lid. Then, the external negative pressure device evacuates the air, thereby removing the gas in the suction cup, the connecting channel, and the negative pressure pipe. This causes the suction cup to adhere to the bucket lid, thus gripping the bucket lid. After the bucket lid is pressed onto the bucket body, the external negative pressure device vents the negative pressure pipe, ultimately causing the suction cup to release its grip on the bucket lid.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a paint bucket sealing device.

[0034] Reference Figures 1 to 4 A paint bucket packaging device is disclosed, including a frame 1 and a packaging component 2 disposed on the frame 1. The frame 1 has a packaging position and a loading position located on the side of the packaging position. The packaging component 2 includes a pressing and gripping structure 21 and a driving structure 22. The driving structure 22 is used to drive the pressing and gripping structure 21 to move between the packaging position and the loading position. The pressing and gripping structure 21 can grip the bucket lid located at the loading position and can drive the bucket lid to the packaging position under the action of the driving structure 22 and apply downward pressure to the bucket lid.

[0035] When using the paint bucket sealing device of this application, the stacked bucket lids are placed in the loading position, and then the bucket body is placed in the sealing position. The drive structure 22 drives the pressing and gripping structure 21 to move the pressing and gripping structure 21 to the loading position. Then, the pressing and gripping structure 21 grips the bucket lid located in the loading position. Then, the drive structure 22 drives the pressing and gripping structure 21 in the opposite direction, so that the pressing and gripping structure 21 moves the gripped bucket lid to the sealing position, so that the bucket lid is located directly above the bucket body. Then, the pressing and gripping structure 21 applies downward pressure to the bucket lid, so that the bucket lid moves downward under the action of the pressing and gripping structure 21 and applies downward pressure to the bucket lid to press the bucket lid onto the bucket body, thereby completing the sealing of the paint bucket.

[0036] When using the paint bucket sealing device in the application to seal paint buckets, the need for manual installation of the lid onto the bucket body is avoided, thus reducing the labor cost of sealing paint buckets and improving the sealing efficiency.

[0037] This application does not specifically limit the press-fit gripping structure 21; preferably, refer to... Figure 1 and Figure 2 The pressing and gripping structure 21 includes a motion seat 211, a power component 212 disposed on the motion seat 211, a pressing plate 213 disposed on the power component 212, and a negative pressure pipe 214 passing through the motion seat 211. The motion seat 211 is slidably connected to the frame 1 and can move between the packaging position and the loading position. The power component 212 is used to drive the pressing plate 213 to move so that the pressing plate 213 applies downward pressure to the barrel lid. The pressing plate 213 is provided with a negative pressure chamber 217 with the cavity opening facing downward, and the negative pressure pipe 214 is connected to the negative pressure chamber 217.

[0038] When using the paint bucket sealing device of this application, the negative pressure pipe 214 is first connected to an external negative pressure device. When gripping the bucket lid, the drive structure 22 drives the moving seat 211, causing the moving seat 211 to move from the sealing position toward the loading position, so that the pressing plate 213 moves to the loading position. Then, the power component 212 drives the pressing plate 213, causing the pressing plate 213 to move toward the bucket lid located at the loading position, so that the pressing plate 213 abuts against the bucket lid. Then, the external negative pressure device evacuates the negative pressure pipe 214 to form a vacuum in the negative pressure chamber 217, thereby... The lid is then held in place by the pressure plate 213 under negative pressure. The power unit 212 drives the pressure plate 213 upward, causing the lid to move upward. The drive structure 22 then drives the motion seat 211 to the sealing position. Once the motion seat 211 is in the sealing position, the lid is directly above the container. The power unit 212 then drives the pressure plate 213 downward, causing the lid to move downward. Finally, the lid is pressed into the container by the pressure plate 213 and the power unit 212, thus completing the sealing of the paint container.

[0039] Since the negative pressure pipe 214 passes through the pressure plate 213, it can not only transport gas, but also guide the pressure plate 213, thereby increasing the stability of the pressure plate 213.

[0040] This application does not specifically limit the material of the negative pressure tube 214. Preferably, the negative pressure tube 214 is made of a metal material, such as iron, copper, or aluminum, to give it a certain rigidity, thereby enabling the sliding fit between the negative pressure tube 214 and the motion seat 211 to guide the pressing plate 213. In other embodiments, the negative pressure tube 214 can also be made of other materials such as plastic.

[0041] This application does not specifically limit the structure of the power component 212. Preferably, the power component 212 is a cylinder. The cylinder body is fixedly connected to the motion seat 211, and the piston rod of the cylinder passes through the motion seat 211 and is fixedly connected to the pressing plate 213, so as to use the cylinder to start the movement of the pressing plate 213, thereby realizing the pressing plate 213 applying downward pressure to the barrel lid.

[0042] It is understandable that the negative pressure pipe 214 is set parallel to the piston rod of the cylinder, which on the one hand ensures the normal movement of the pressing plate 213, and on the other hand ensures the guiding effect of the negative pressure pipe 214 on the pressing plate 213.

[0043] In other embodiments, the power component 212 may also be a hydraulic cylinder, an electric actuator, or other structure capable of driving the pressing plate 213 to perform linear motion.

[0044] Furthermore, refer to Figure 4 The pressure plate 213 has a negative pressure channel 219 inside, and a suction cup 218 connected to the negative pressure channel 219 is provided in the negative pressure chamber 217. The negative pressure pipe 214 is connected to the negative pressure channel 219.

[0045] It is understandable that the suction cup 218 is fixedly connected to the pressure plate 213 so that after the suction cup 218 is attached to the lid, the suction cup 218 can move the lid to the sealing position under the action of the pressure plate 213.

[0046] After the pressing plate 213 is pressed against the bucket lid, the suction cup 218 is pressed against the bucket lid. Then, the external negative pressure device evacuates the air, thereby removing the gas from the suction cup 218, the connecting channel, and the negative pressure pipe 214. This causes the suction cup 218 to adhere to the bucket lid, thus gripping the lid. After the bucket lid is pressed onto the bucket body, the external negative pressure device vents the negative pressure pipe 214, ultimately causing the suction cup 218 to release its grip on the bucket lid.

[0047] Furthermore, refer to Figure 4 The pressing plate 213 is provided with a downward-facing receiving cavity 221. The cross-sectional shape of the receiving cavity 221 is adapted to the barrel lid, and the negative pressure cavity 217 is located at the center of the receiving cavity 221.

[0048] Understandably, after the suction cup 218 is attached to the lid, at least a portion of the top of the lid extends into the receiving cavity 221.

[0049] Because the pressing plate 213 is provided with a downward-facing receiving cavity 221, the cross-sectional shape of which is adapted to the barrel lid, the barrel lid can be inserted into the receiving cavity 221 when the pressing plate 213 grips the barrel lid, thereby achieving the positioning of the barrel lid and realizing the effect of precise pressing of the barrel lid. In addition, it also increases the contact area between the pressing plate 213 and the barrel lid, thereby increasing the connection stability between the barrel lid and the pressing plate 213.

[0050] Furthermore, refer to Figure 4 The accommodating cavity 221 has an annular groove 222 corresponding to the rib of the bucket lid, and the negative pressure channel 219 has a connecting hole 223 communicating with the annular groove 222.

[0051] Understandably, after the lid is inserted into the receiving cavity 221, the top of the protruding rib on the lid contacts the opening of the connecting hole 223.

[0052] Since the annular groove 222 is designed to correspond to the ribs of the bucket lid, and the negative pressure channel 219 has a connecting hole 223 that communicates with the annular groove 222, the position of the annular groove 222 can also adsorb the bucket lid when it is gripped, thereby increasing the gripping stability of the bucket lid.

[0053] This application does not specify a particular number of negative pressure tubes 214; preferably, refer to... Figure 1 At least two negative pressure pipes 214 are provided at intervals and are located on both sides of the power component 212 respectively. The pressure plate 213 is provided with an air connector that communicates with the negative pressure channel 219. The negative pressure pipes 214 are threadedly connected to the air connector.

[0054] It is understandable that the air connector is integrally formed on the pressure plate 213, or the air connector is fixedly connected to the pressure plate 213 by other means.

[0055] Since at least two negative pressure pipes 214 are provided at intervals and are located on both sides of the power component 212, the sliding fit points between the negative pressure pipes 214 and the motion seat 211 are increased, thereby further increasing the motion stability of the motion seat 211. At the same time, since the negative pressure pipes 214 are threadedly connected to the air connector, the difficulty of assembling the negative pressure pipes 214 with the pressure plate 213 is reduced, thereby reducing the production difficulty of the paint bucket sealing device.

[0056] In other embodiments, multiple negative pressure pipes 214 may be evenly spaced along the circumference of the power member 212.

[0057] In other embodiments, the press-grip structure 21 can also be a robotic arm or other structures.

[0058] In a preferred embodiment, refer to Figure 3The top of the frame 1 has a support beam 11 located at the bottom of the motion seat 211 and a limiting beam 12 located at the top of the motion seat 211. The support beam 11 is provided with a guide rail 111, and the bottom of the motion seat 211 is provided with a slider 215 that slides with the guide rail 111.

[0059] Understandably, the top of the frame 1 forms a space for installing the motion seat 211, the support beam 11 is used to support the motion seat 211, and the limiting beam 12 is used to limit the motion seat 211.

[0060] Since the support beam 11 is located at the bottom of the motion seat 211, it can support the motion seat 211, thereby increasing the stability of the motion seat 211. Since the limiting beam 12 is located at the top of the motion seat 211, it can limit the motion seat 211, thereby preventing the motion seat 211 from detaching from the support beam 11. Furthermore, since the support beam 11 is provided with a guide rail 111, and the bottom of the motion seat 211 is provided with a slider 215 that slides with the guide rail 111, the sliding engagement between the slider 215 and the guide rail can guide the movement of the motion seat 211, thereby further increasing the movement stability of the motion seat 211.

[0061] This application does not impose specific limitations on the connection method between the slider 215 and the motion seat 211. Preferably, the slider 215 is integrally formed into the motion seat 211 to increase the connection stability between the two. In other embodiments, the slider 215 can also be fixedly connected to the motion seat 211 by means of screws or other methods.

[0062] Furthermore, refer to Figure 3 The top of the motion seat 211 is provided with a roller 216. The rotation axis of the roller 216 is perpendicular to the length direction of the guide rail 111, and the outer peripheral surface of the roller 216 contacts the limiting beam 12.

[0063] It is understandable that when the motion seat 211 moves under the action of the drive structure 22, the roller 216 rolls relative to the limiting beam 12.

[0064] Since the top of the motion seat 211 is provided with a roller 216, the rotation axis of the roller 216 is set perpendicular to the length direction of the guide rail 111, and the outer peripheral surface of the roller 216 contacts the limiting beam 12, the roller 216 and the limiting beam 12 roll relative to each other when the motion seat 211 moves. On the one hand, this ensures the limiting effect of the limiting beam 12 on the motion seat 211, and on the other hand, it reduces the friction between the motion seat 211 and the limiting beam 12, thereby reducing the driving load of the drive structure 22.

[0065] This application does not specifically limit the drive structure 22. Preferably, the drive structure 22 includes a cylinder, the cylinder body of which is fixedly connected to the frame 1, and the piston rod of which is fixedly connected to the motion seat 211. When the piston rod of the cylinder retracts or extends, the piston rod drives the motion seat 211 to move between the loading position and the packaging position. In other embodiments, the drive structure 22 may also include a linear motor, a hydraulic cylinder, an electric actuator, or other structures capable of driving the motion seat 211 to move between the loading position and the packaging position.

[0066] In a preferred embodiment, refer to Figure 1 The paint bucket sealing device also includes a feeding component 3 located at the feeding position. The feeding component 3 includes a base 31, a storage tank 32 located above the base 31, a push plate 33 located in the storage tank 32, and an actuator 34 located on the base 31 for driving the push plate 33 to move in the vertical direction.

[0067] It is understandable that the top opening of the storage tank 32 is provided so that the lid can be inserted into the storage tank 32 through the top opening of the storage tank 32. After the pressing gripping structure 21 moves to the loading position, the pressing plate 213 is located directly above the storage tank 32.

[0068] When placing the lids, multiple lids are placed in the storage tank 32 so that multiple lids are stored in the storage tank 32. Then, as the lids are continuously gripped by the pressing and gripping structure 21, the actuator 34 can be used to push the push plate 33 upward, so that the push plate 33 pushes the lid upward, thereby reducing the downward distance required for the pressing and gripping structure 21 to grip the lid, and thus improving the sealing efficiency of the paint bucket.

[0069] This application does not specifically limit the structure of the actuator 34. Preferably, the actuator 34 is a cylinder mounted on the base 31, with the cylinder body fixedly connected to the base 31. The piston rod of the cylinder passes through the base 31, extends into the storage tank 32, and is connected to the push plate 33, so that the actuator 34 drives the push plate 33 to move upward. In other embodiments, the actuator 34 may also be a hydraulic cylinder, an electric actuator, or other structures capable of driving the push plate 33 to move upward.

[0070] In a preferred embodiment, refer to Figure 1 and Figure 2 The paint bucket sealing device also includes a roller conveyor 4 located at the sealing position, and a pressing and gripping structure 21 located above the roller conveyor.

[0071] When sealing paint buckets, the buckets can be placed on roller conveyor 4, and then the roller conveyor 4 can be used to transport the buckets to the sealing position, thereby further realizing the automation level of pressing paint buckets. At the same time, the pressing gripping structure 21 can be used to grip the lid while the roller conveyor 4 is transporting the buckets, thereby further improving the sealing efficiency of paint bucket lids.

[0072] This application does not specify the specific structure of the roller conveyor 4, but may refer to the prior art.

[0073] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
