Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a capping device for barrel-type fireproof coating. Background Technology

[0002] Fire-retardant coatings, due to their high solids content and tendency to settle, are typically packaged in sealed metal drums. With the rapid expansion of green building and high-rise steel structure projects, coating output has surged, placing higher demands on the production cycle and sealing reliability of the filling and capping process. Traditional operations rely on manual handling of drum caps and hand-held capping devices for sealing, resulting in high labor intensity and a production cycle affected by human factors.

[0003] Existing production lines mostly use manual capping and a rotating pressing plate. The operator places the cap on the barrel opening and then presses it down with a pressing pliers while rotating the cap to complete the edge rolling. Although this solution reduces physical labor, the cap pre-positioning process still requires manual supervision. The rotating pressing plate is sensitive to the ovality of the barrel opening, often resulting in uneven edge rolling and sealing failure. The current problem is that the cap supply, barrel positioning, and capping action are carried out in stages, lacking synchronous coordination. This leads to unstable capping rhythm and insufficient positioning accuracy, making it difficult to meet the requirements of continuous production. Utility Model Content

[0004] The purpose of this utility model is to propose a barrel-type fire-retardant coating capping device to solve the technical problem that the barrel cap supply, barrel positioning and capping action cannot be synchronized and coordinated in the prior art.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A capping device for fire-retardant coating in drums includes a conveyor belt with drums loaded with fire-retardant coating arranged on top; a support frame spanning the conveyor belt, on which sealing claws for sealing the drum caps are vertically mounted; a drive mechanism vertically mounted on the support frame and driving the sealing claws to perform the sealing operation; and a cap supply mechanism spanning the conveyor belt and located on one side of the support frame, which supplies the caps to the top of the drums when the drums move to the lower part of the cap supply mechanism.

[0007] By adopting the above technical solution, the cap supply, positioning, and cap pressing are integrated into the same conveying path. By using a transverse support frame and synchronously lifting sealing claws, continuous cooperation between the barrel cap and the barrel is achieved, shortening the cycle interval and improving positioning consistency.

[0008] Furthermore, a drive cylinder is provided on one side of the conveyor belt along its length to block the movement of the cylinder, and clamping members are provided on both sides of the conveyor belt along its length to hold the cylinder.

[0009] By adopting the above technical solution, the drive cylinder and the clamping component move synchronously at the cap feeding and cap pressing stations, and the barrel is accurately positioned and fixed, avoiding capping failure caused by barrel displacement.

[0010] Furthermore, the support frame includes guide columns fixedly disposed on both sides of the conveyor belt and a top plate installed on the top of the guide columns, and a hydraulic cylinder for driving the sealing claw to rise and fall is installed on the top plate.

[0011] By adopting the above technical solution, the guide column and the top plate form a rigid gantry frame, and the hydraulic cylinder directly drives the sealing claw to rise and fall smoothly along the direction of the guide column, ensuring that the sealing force acts vertically on the center of the lid.

[0012] Furthermore, a panel is raised and lowered on the guide column, a U-shaped frame is fixedly installed on the top surface of the panel, the piston rod of the hydraulic cylinder is fixedly connected to the U-shaped frame, and the drive mechanism is installed on the panel.

[0013] By adopting the above technical solution, the panel and the U-shaped frame form an integrated lifting module, and the drive mechanism moves synchronously with the panel, reducing the length of the transmission chain and improving the response speed.

[0014] Furthermore, a damper for buffering is provided between the hydraulic cylinder and the U-shaped frame.

[0015] By adopting the above technical solution, the damper absorbs the impact load when the sealing claw contacts the barrel lid, avoiding instantaneous overload that could cause barrel lid deformation or barrel damage.

[0016] Furthermore, the sealing claw includes a base that abuts against the barrel lid, a column fixedly mounted on the base and fixedly connected to the U-shaped frame, a pressure plate slidably mounted on the column, and a swing clamp rotatably connected to the base, with a connecting rod rotatably connected to the edge of the pressure plate and the top of the swing clamp.

[0017] By adopting the above technical solution, the pressure plate slides along the column and is driven by the connecting rod to swing the clamp to retract synchronously, so that the edge of the bucket lid is evenly stressed to complete the rolling and ensure consistent sealing.

[0018] Furthermore, multiple sets of the connecting rod and the swing clamp are arranged around the circular axis of the base.

[0019] By adopting the above technical solution, multiple sets of connecting rods and swing clamps are evenly distributed along the circumference, and the bucket lid is subjected to balanced forces in all directions, avoiding the risk of leakage caused by insufficient local rolling.

[0020] Furthermore, the driving mechanism includes a motor fixedly mounted on the panel, a threaded sleeve passing through the motor, and a round sleeve that drives the pressure plate to rise and fall and passes through the column, wherein the round sleeve is screwed to the threaded sleeve.

[0021] By adopting the above technical solution, the motor-threaded sleeve-round sleeve form a precision helical transmission, and the lifting stroke of the pressure plate is controllable, which can adapt to the edge rolling requirements of barrel lids of different heights.

[0022] Furthermore, the lid supply mechanism includes a platform spanning the conveyor belt, a cylindrical bin vertically disposed on the platform for placing the lid, a pusher plate for pushing the lid out of the cylindrical bin, and a linear module for driving the pusher plate.

[0023] By adopting the above technical solution, the barrel lids are stacked inside the silo, and the pusher plate pushes them out one by one under the drive of the linear module, realizing uninterrupted lid supply that matches the rhythm of the conveyor belt.

[0024] Furthermore, the platform is provided with a groove for the bucket lid to slide laterally, and the push plate and the linear module are respectively disposed in the groove, the height of the groove being the same as the thickness of the bucket lid.

[0025] By adopting the above technical solution, the groove restricts the stacking and lateral movement of the bucket lids, and the pusher plate pushes only a single bucket lid at a time, ensuring lid supply accuracy and avoiding jamming.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The barrel fireproof coating capping device of this utility model integrates barrel cap supply, barrel positioning, and capping action by arranging the cap supply mechanism, support frame, and sealing claws sequentially along the conveyor belt, significantly shortening the cycle time. The drive cylinder and clamping components work together to accurately position and fix the barrel at the cap supply and capping stations, avoiding capping failure caused by barrel misalignment. The hydraulic cylinder-damper combination provides smooth lifting and buffering to prevent damage to the barrel cap or barrel body caused by instantaneous impact. Multiple sets of connecting rods and swing clamps uniformly roll the edge, combined with precision screw transmission, to ensure consistent sealing and adapt to barrel caps of different specifications.

[0048] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0049] This embodiment relates to a capping device for barrel-packaged fire-retardant coating. In terms of overall structure, as follows... Figure 1 and Figure 2 As shown, it includes a conveyor belt 1, a support frame 2, a sealing claw 7, a drive mechanism 8, and a cap supply mechanism 9.

[0050] The conveyor belt 1 carries barrels loaded with fire-retardant coating. A support frame 2 spans across the conveyor belt 1. Sealing claws 7, which are raised and lowered on the support frame 2, seal the barrel lids onto the barrels. A drive mechanism 8 drives the sealing claws 7 to perform the sealing operation. A lid supply mechanism 9 spans across the conveyor belt 1 and is located on one side of the support frame 2. When the barrels move to the lower part of the lid supply mechanism 9, the lid supply mechanism 9 delivers the lids to the top of the barrels.

[0051] It is worth mentioning that the barrel moves from one end to the other along the conveyor belt 1. First, a barrel lid is delivered to the barrel by the lid supply mechanism 9, and then it moves to the bottom of the sealing claw 7. The sealing claw 7 descends to the top of the barrel lid to seal it. After sealing, it is then conveyed out by the conveyor belt 1. The support frame 2 is installed on both sides of the length of the conveyor belt 1 to ensure that it does not affect the movement of the conveyor belt 1. When the barrel moves to the bottom of the sealing claw 7, the sealing claw 7 descends to abut against the barrel lid. Then, the drive mechanism 8 drives the sealing claw 7 to seal the barrel lid on the barrel. The lid and the barrel are common press-fit loading containers in the prior art, which will not be described in detail here.

[0052] In addition, a drive cylinder 10 is vertically installed on one side of the conveyor belt 1 along its length. The drive rod of the drive cylinder 10 extends across the conveyor belt 1. Drive cylinders 10 are also installed on the support frame 2 and the lid supply mechanism 9. When the sealing claw 7 seals the lid, the drive cylinder 10 can block the movement of the cylinder, preventing it from moving out of the working position of the sealing claw 7. When the lid supply mechanism 9 delivers the lid to the cylinder, the drive cylinder 10 can also block the movement of the cylinder, ensuring that the lid falls accurately onto the top of the cylinder. After the sealing operation and lid placement are completed, the drive rod of the drive cylinder 10 retracts, and the cylinder continues to move with the conveyor belt 1. To improve the stability of the cylinder, clamping parts 11 can be installed on both sides of the conveyor belt 1 along its length during the sealing operation and lid placement to hold the cylinder and prevent it from deviating. The clamping parts 11 consist of an electric cylinder and a top block. The electric cylinder is installed on the conveyor belt 1, and the top block moves with the drive rod of the drive cylinder 10 to abut the cylinder, thereby achieving clamping.

[0053] Based on the above overall introduction, this embodiment presents an exemplary structure of the barrel-type fire-retardant coating capping device, such as... Figure 2 and Figure 3 As shown, the support frame 2 includes guide columns 201 fixedly installed on both sides of the conveyor belt 1 and a top plate 202 installed on the top of the guide columns 201. A panel 4 for installing the drive mechanism 8 is lifted and lowered on the guide columns 201. A U-shaped frame 5 is fixedly installed on the panel 4. A hydraulic cylinder 3 for driving the panel 4 to rise and fall is installed on the top plate 202. The piston rod of the hydraulic cylinder 3 is fixedly connected to the U-shaped frame 5. The sealing claw 7 passes through the panel 4 and the drive mechanism 8 and is fixedly connected to the U-shaped frame 5.

[0054] It should be noted that four guide columns 201 can be used, with two columns on each side of the conveyor belt 1. This arrangement can improve the stability of the panel 4 lifting and lowering. The panel 4 passes through the four guide columns 201, ensuring that the panel 4 can remain horizontal while lifting and lowering on the four guide columns 201. The top plate 202 is used to install the hydraulic cylinder 3. The piston rod of the hydraulic cylinder 3 passes through the top plate 202 and is connected to the U-shaped frame 5. When the piston rod of the hydraulic cylinder 3 extends or retracts, it can drive the panel 4 to lift and lower. The sealing claw 7 follows the lifting and lowering of the panel 4. This arrangement ensures that the sealing claw 7 can rise again to perform sealing operation after sealing the barrel lid. The U-shaped frame 5 can be set across the drive mechanism 8 to avoid affecting the installation of the drive mechanism 8. The sealing claw 7 is directly installed on the U-shaped frame 5 to ensure that the drive mechanism 8 can drive the sealing claw 7 to work.

[0055] As a preferred implementation method, such as Figure 4 and Figure 5As shown, the sealing claw 7 in this embodiment includes a base 701 that abuts against the bucket lid, a column 702 fixedly mounted on the base 701 and connected to the U-shaped frame 5, a pressure plate 703 slidably mounted on the column 702, a swing clamp 704 rotatably connected to the base 701 for clamping the bucket lid, and a connecting rod 705 rotatably connected between the pressure plate 703 and the swing clamp 704.

[0056] Specifically, the column 702 is fixedly installed in the middle of the base 701, and its top passes through the panel 4 and the drive mechanism 8 and is connected to the U-shaped frame 5. This arrangement ensures that the base 701 can rise and fall with the hydraulic cylinder 3. When the base 701 descends, it presses down on the barrel lid. The drive mechanism 8 controls the pressure plate 703 to descend. The pressure plate 703 passes through the column 702 in the middle. When the pressure plate 703 descends, it drives the connecting rod 705 to move. The connecting rod 705 pushes the swing clamp 704 to rotate. The swing clamp 704 fits the sealing edge of the barrel lid onto the barrel. This arrangement completes the sealing of the barrel and the barrel lid. There are multiple sets of connecting rods 705 and swing clamps 704 around the base 701 to ensure that each sealing edge of the barrel lid can be pressed onto the barrel.

[0057] As a preferred implementation method, such as Figure 6 As shown, in this embodiment, the drive mechanism 8 includes a motor 801 fixedly mounted on the panel 4, a threaded sleeve 802 passing through the motor 801, and a circular sleeve 803 fixedly mounted on the pressure plate 703 and passing through the column 702. The circular sleeve 803 and the threaded sleeve 802 are screwed together. Specifically, the motor 801 is fixedly mounted on the panel 4, the motor 801 and the threaded sleeve 802 are keyed together, the circular sleeve 803 is fixedly connected to the pressure plate 703, and can slide on the column 702. When the motor 801 starts, it drives the threaded sleeve 802 to rotate. Since the threaded sleeve 802 and the circular sleeve 803 are screwed together, the circular sleeve 803 can move up and down under the drive of the threaded sleeve 802, and the pressure plate 703 will move up and down with the circular sleeve 803. This arrangement realizes the swing of the swing clamp 704. The bottom of the swing clamp 704 and the top edge of the cylinder have the same shape. When the sealing edge of the barrel lid enters the swing clamp 704, it will completely adhere the sealing edge to the barrel.

[0058] As a preferred option, such as Figure 7As shown, in this embodiment, a damper 6 is provided between the hydraulic cylinder 3 and the U-shaped frame 5 to provide a buffering effect. The lid feeding mechanism 9 includes a platform 901 spanning the conveyor belt 1, a cylindrical chamber 902 vertically arranged on the platform 901 for placing the lid, a push plate 903 for pushing the lid out of the cylindrical chamber 902, and a linear module 904 for driving the push plate 903 to move. The platform 901 is provided with a groove 905 for the lid to slide laterally, and the push plate 903 is slidably arranged in the groove 905. It should be noted that the platform 901 is mounted on top of the conveyor belt 1 via support legs, which are fixedly mounted on both sides of the conveyor belt 1 along its length. The cylindrical bin 902 is mounted on top of the groove 905, and the height of the groove 905 is the same as the thickness of the barrel lid. After the barrel lid in the cylindrical bin 902 falls into the groove 905, the linear module 904 drives the push plate 903 to move. The push plate 903 pushes the barrel lid out of the groove 905. At this time, the cylindrical bin is blocked by the drive cylinder 10 at the barrel lid output position. This setting ensures that the barrel lid can be pushed to the top of the cylindrical bin. The linear module 904 can be an electric cylinder, which is also installed in the groove 905 to ensure that the push plate 903 can directly push the barrel lid out.

[0059] In this embodiment, the barrel fireproof coating capping device integrates barrel cap supply, barrel positioning, and capping actions by arranging the cap supply mechanism 9, support frame 2, and sealing claw 7 sequentially along the conveyor belt 1, significantly shortening the cycle interval. The drive cylinder 10 and clamping component 11 work together to precisely position and fix the barrel at the cap supply and capping stations, avoiding capping failure caused by barrel displacement. The combination of hydraulic cylinder 3 and damper 6 provides smooth lifting and buffering to prevent damage to the barrel cap or barrel body caused by instantaneous impact. Multiple sets of connecting rods 705 and swing clamps 704 uniformly roll the edges, combined with precision screw transmission, to ensure consistent sealing and adapt to barrel caps of different specifications.

[0060] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
