Description

Technical Field

[0001] This utility model relates to the field of paint filling technology, and in particular to a paint bucket capping machine. Background Technology

[0002] A paint bucket capping machine is a machine used to seal the caps of paint buckets or other liquid containers. It can quickly and accurately press the cap onto the paint bucket or other liquid container, ensuring the product's airtightness and quality, and preventing leakage or contamination. A paint bucket capping machine typically consists of two parts: a clamping base and a capping head. Two opposing arc-shaped clamps on the base fix the outer wall of the paint bucket, while the capping head presses the top cap tightly onto the paint bucket. However, during use, because paint buckets of different sizes have varying diameters, the two opposing arc-shaped clamps cannot perfectly fit and fix different sizes of paint buckets, causing the paint bucket to easily shift during the capping process.

[0003] According to Chinese Patent Publication No. CN222540448U, a paint bucket capping machine is proposed. A motor drives a threaded rod to rotate, which, through the cooperation of a movable block and a connecting rod, synchronously drives four clamping blocks to move closer together, thus centering the paint bucket. Simultaneously, the machine clamps and fixes the outer wall of the paint bucket from four directions, enabling simultaneous fixation of the paint bucket's outer wall from four directions. It also automatically centers the paint bucket, preventing displacement during capping and ensuring accuracy. By pulling the positioning rod to disengage it from the positioning hole, and then using a clamping plate to block the positioning plate, the machine allows workers to quickly and easily change different capping heads using both hands. This enables convenient and rapid capping head changes, shortening preparation time and improving capping efficiency when processing paint buckets of different sizes.

[0004] The application document can fix paint buckets of different sizes when in use. However, in actual use, the worker needs to place the paint bucket on the workbench and then put on the lid. At this time, the worker's hand will be under the capping head along with the paint bucket or lid, which poses some safety hazards to the worker during operation. Therefore, a paint bucket lid capping machine is proposed to solve the above problems. Utility Model Content

For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1-3 As shown, the present invention proposes a paint bucket capping machine, which includes a base 1, an L-shaped support 2 on the outside of the base 1, and a capping structure 3 inside the L-shaped support 2.

[0024] In this utility model, the L-shaped bracket 2 can be used to install the capping structure 3, and the capping structure 3 can be used to cap the paint bucket. During the capping process, the top outer side of the paint bucket can also be protected to avoid the safety hazard caused by the worker's hand being above the paint bucket cap.

[0025] In an optional embodiment, the pressure cap structure 3 includes a first screw 31, a handle 32, a lifting circular plate 33, two guide rods 34, a protective component 35, and a pressing component 36. The first screw 31 is threadedly connected to the top of the L-shaped bracket 2 and extends into it. The handle 32 is located at the top of the first screw 31. The lifting circular plate 33 is rotatably connected to the bottom of the first screw 31. Both guide rods 34 are located at the top of the lifting circular plate 33 and extend to the top of the L-shaped bracket 2. Both guide rods 34 are slidably connected to the L-shaped bracket 2. The protective component 35 is located on the outside of the lifting circular plate 33, and the pressing component 36 is located at the bottom of the lifting circular plate 33.

[0026] It should be noted that when the handle 32 is turned, the handle 32 will drive the first screw 31 to rotate. Under the action of the two guide rods 34, the lifting plate 33 will not rotate. When the first screw 31 rotates, under the action of the thread thrust, the first screw 31 will drive the lifting plate 33 to move up or down. The lifting plate 33 will drive the protective component 35 and the pressing component 36 to move up or down, so that the protective component 35 and the pressing component 36 correspond to the top position of the paint bucket. This allows the protective component 35 and the pressing component 36 to adapt to paint buckets of different sizes, thereby improving the capping efficiency of the paint bucket.

[0027] In an optional embodiment, the protective assembly 35 includes two ear plates 351, two first cylinders 352, two mounting plates 353, and a protective ring 354. The two ear plates 351 are both located on the outside of the lifting circular plate 33 and are symmetrically distributed. The two first cylinders 352 are respectively located at the bottom of the two ear plates 351. The two mounting plates 353 are respectively located on the piston rods of the two first cylinders 352. The protective ring 354 is located between the opposite sides of the two mounting plates 353.

[0028] It should be noted that after the position of the protective component 35 is adjusted, the paint bucket and lid are placed first, and then the two first cylinders 352 are activated. The piston rods of the two first cylinders 352 will drive the two mounting plates 353 to move up or down respectively. The two mounting plates 353 will drive the protective ring 354 to move up or down until the protective ring 354 blocks the inner pressing component 36 and the lid. Then the pressing component 36 can be activated to press the lid of the paint bucket, so that the lid is stably installed and the sealing of the lid is ensured.

[0029] In an optional embodiment, the pressing assembly 36 includes a U-shaped frame 361, a second cylinder 362, a connecting circular plate 363, an installation module 364, and a pressing head 365. The U-shaped frame 361 is located at the bottom of the lifting circular plate 33, the second cylinder 362 is located on the inner bottom wall of the U-shaped frame 361 and extends to its bottom, the connecting circular plate 363 is located on the piston rod of the second cylinder 362, the pressing head 365 is located at the bottom of the connecting circular plate 363, and the installation module 364 is located on the outer side of the connecting circular plate 363. The connecting circular plate 363 is connected to the pressing head 365 through the installation module 364.

[0030] It should be noted that when the protective ring 354 protects the inner pressing component 36 and the lid, the second cylinder 362 is activated. The piston rod of the second cylinder 362 will drive the connecting round plate 363 to move downward. Under the action of the installation module 364, the connecting round plate 363 will drive the pressing head 365 to move downward. The pressing head 365 presses the lid of the paint bucket to ensure the sealed installation of the paint bucket lid.

[0031] In an optional embodiment, the mounting module 364 includes two mounting blocks 3641, two mounting grooves 3642, two connecting blocks 3643, two threaded grooves 3644, two second screws 3645, and two knobs 3646. The two mounting blocks 3641 are both located on the outer side of the connecting circular plate 363 and are symmetrically distributed. The two mounting grooves 3642 are respectively opened at the bottom of the two mounting blocks 3641. The two connecting blocks 3643 are both located at the top of the pressing head 365. The two connecting blocks 3643 are slidably connected to the inside of the two mounting grooves 3642. The two threaded grooves 3644 are respectively opened on opposite sides of the two connecting blocks 3643. The two second screws 3645 are respectively located on opposite sides of the two mounting blocks 3641 and extend into the inside of the two threaded grooves 3644. The two second screws 3645 are threadedly connected to the two threaded grooves 3644. The two knobs 3646 are respectively located at opposite ends of the two second screws 3645.

[0032] It should be noted that when dealing with paint buckets of different sizes, the pressing head 365 of different sizes can be replaced by installing module 364, which can ensure that the preparation time can be shortened and the capping efficiency can be improved when processing paint buckets of different sizes.

[0033] When the press head 365 needs to be replaced, turn the two knobs 3646. The two knobs 3646 will drive the two second screws 3645 to rotate. Under the action of the thread thrust, the two second screws 3645 will move to opposite sides. When the two second screws 3645 are disengaged from the two threaded grooves 3644, the two connecting blocks 3643 can be removed from the two mounting grooves 3642, thereby removing the press head 365.

[0034] In addition, when installing the press head 365, the two connecting blocks 3643 need to be slidably connected to the inside of the two mounting slots 3642 respectively. Then, rotate the two knobs 3646 in opposite directions. The two second screws 3645 will move to the opposite side. When the two second screws 3645 are engaged with the two threaded grooves 3644 respectively, the two connecting blocks 3643 can be fixed by the two second screws 3645 and the two threaded grooves 3644 respectively, thereby fixing the press head 365.

[0035] In an optional embodiment, the base 1 has four evenly distributed support columns 4 on its top, the four support columns 4 have a worktable 5 on their top, and the base 1 has a fixing structure 6 extending to the top of the worktable 5.

[0036] It should be noted that the workbench 5 can be supported by four support columns 4, and the paint buckets can be placed on the workbench 5. After the paint buckets are placed, the fixing structure 6 can fix the paint buckets of different sizes.

[0037] In addition, the fixed structure 6 includes four sliding grooves inside the workbench 5, with sliders slidably connected inside the grooves. Clamping blocks are fixedly connected to the top of the sliders. A motor is fixedly connected to the top center of the base 1. A threaded rod is fixedly connected to the output end of the motor. A movable block is threadedly connected to the outer circumference of the threaded rod. A connecting rod is provided between the movable block and the slider. When the motor is started, the output shaft of the motor will drive the threaded rod to rotate. Under the action of the threaded thrust, the threaded rod will drive the movable block to move downward. Under the action of the connecting rod, the four sliders will move inward. The four sliders will drive the four clamping blocks to move inward respectively. The paint bucket can be fixed by the four clamping blocks.

[0038] In an optional embodiment, a controller is provided on the outside of the workbench 5. The first cylinder 352, the second cylinder 362, and the motor are all electrically connected to the controller. The controller can control the first cylinder 352, the second cylinder 362, and the motor. Each of the two first cylinders 352 is equipped with a throttle valve. The operating speed of one first cylinder 352 is used as a reference to adjust the movement speed of the other first cylinder 352 so that the two first cylinders 352 are synchronized within the relative error range. Then, the two first cylinders 352 are connected to the two mounting plates 353 together, thereby ensuring that the two first cylinders 352 can drive the protective ring 354 to move stably upward or downward.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
