[0002] The paint bucket lid capping machine is a machine used to seal the lids of paint buckets or other liquid containers. The paint bucket lid capping machine can quickly and accurately press the lids tightly on the paint buckets or other liquid containers to ensure the sealing and quality of the products and avoid leakage or contamination of liquid products.

[0003] The paint bucket capping machine usually consists of two parts: a clamp base and a capping head. The outer wall of the paint bucket is fixed by two arc-shaped clamps in opposite directions on the base, and the top cover of the paint bucket is pressed and sealed on the paint bucket in cooperation with the capping head.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 2The utility model provides an embodiment: a paint bucket capping machine, comprising a base 1, a processing table 2 is fixedly connected to the top of the base 1, the base 1 and the processing table 2 are the main supporting parts of the capping machine, which are used to hold the paint bucket, so as to facilitate the capping of the paint bucket later. Four slide grooves 3 are provided inside the processing table 2, a slider 4 is slidably connected inside the slide groove 3, a clamping block 5 is fixedly connected to the top of the slider 4, and the four clamping blocks 5 are equidistantly distributed on the circumference, so that the four clamping blocks 5 can realize all-round limit fixing of the paint bucket. A motor 6 is fixedly connected to the middle side of the top of the base 1, and a threaded rod 7 is fixedly connected to the output end of the motor 6. A movable block 8 is threadedly connected to the outer periphery of the threaded rod 7. A connecting rod 9 is arranged between the movable block 8 and the slider 4. The motor 6 is started to drive the threaded rod 7 to rotate, and the movable block 8 is driven downward by the rotation of the threaded rod 7, so that the movable block 8 will synchronously drive the four sliders 4 to move by pulling the four connecting rods 9, and the four sliders 4 will synchronously move toward each other inside the slide groove 3 and approach the center position of the processing table 2. At the same time, the four clamping blocks 5 will also move accordingly, touching the outer wall of the paint bucket and slowly pushing the paint bucket toward the center of the processing table 2, and finally clamping the paint bucket on the processing table 2.

[0032] Reference Figure 1-Figure 2 The top edge of the base 1 is fixedly connected with a bracket 11, the bottom of the bracket 11 is fixedly connected with a connecting column 12, a replacement component is installed at the bottom of the connecting column 12, a mounting shaft 14 is installed at the bottom of the replacement component, a positioning hole 15 is opened inside the mounting shaft 14, and a capping head 16 is fixedly connected at the bottom of the mounting shaft 14. By starting the connecting column 12, the mounting shell 13 and the capping head 16 are pushed downward, so that the capping head 16 moves down and contacts the lid placed on the top of the paint bucket, and pressure is applied to the lid to embed it into the top of the paint bucket, thereby completing the capping process of the paint bucket, sealing the paint bucket, and completing the packaging of the paint. The inside of the slide 3 is fixedly connected with a support rod 10, and the inside of the slider 4 is slidably connected to the outer periphery of the support rod 10. The slider 4 is made by the support rod 10 to prevent the slider 4 from being pulled out of the inside of the slide 3 through the connecting rod 9 when the threaded rod 7 reverses and drives the movable block 8 to move downward, thereby ensuring that the four sliders 4 can be reset so that the clamping block 5 releases the clamped paint bucket. One end of the connecting rod 9 is hinged to the bottom of the slider 4, and the other end of the connecting rod 9 is hinged to the outside of the movable block 8.

At this time, the locking between the mounting shaft 14 and the mounting shell 13 is disengaged. At this time, the worker holds the bottom of the gland head 16 with one hand to continue to pull the positioning rod 17 until it is completely received inside the mounting shell 13. At this time, the clamping plate 20 will fall downward under the action of gravity, and insert into the mounting shell 13 to block the end of the positioning rod 17, so as to prevent the positioning rod 17 from resetting under the action of the spring 18. At this time, the gland head 16 and the mounting shaft 14 can be easily disassembled and replaced. Then, the installation shaft 14 at the top of another type of gland head 16 is inserted into the installation shell 13, and the card plate 20 is pushed upward to disengage it from the installation shell 13. At this time, the compressed spring 18 is reset to push the stopper 19 to drive the positioning rod 17 to reset, and then the positioning rod 17 is inserted into the positioning hole 15 of another type of gland head 16, so that the gland head 16 can be replaced quickly and conveniently. The outer periphery of the installation shaft 14 is slidably connected to the inside of the installation shell 13, and the outer periphery of the positioning rod 17 passes through the installation shell 13 and is inserted into the positioning hole 15.

One end of the spring 18 is fixedly connected to the middle of the stopper 19, and the other end of the spring 18 is fixedly connected to the inner wall of the installation shell 13. The spring 18 can apply a thrust to the stopper 19, thereby ensuring that the positioning rod 17 and the positioning hole 15 will not be separated.

[0034] Working principle: When sealing the paint bucket filled with paint, first put the paint cover on the paint bucket, and then place the paint bucket in the middle of the top of the processing table 2. Start the motor 6 to drive the threaded rod 7 to rotate, and the threaded rod 7 rotates to drive the movable block 8 to move downward, so that the movable block 8 will synchronously drive the four sliders 4 to move by pulling the four connecting rods 9, and the four sliders 4 will synchronously move towards each other inside the slide 3, approaching the center of the processing table 2, and at the same time, the four clamping blocks 5 will also move accordingly, touching the outer wall of the paint bucket and slowly pushing the paint bucket toward the center of the processing table 2. Until the four clamping blocks 5 contact and clamp the outer wall of the paint bucket. At this time, the positioning and clamping of the paint bucket are completed, and at this time, the connecting column 12 is started to push the mounting shell 13 and the capping head 16 downward, so that the capping head 16 moves down and contacts the lid placed on the top of the paint bucket, and applies pressure to the lid to embed it into the top of the paint bucket, and then completes the capping operation of the paint bucket.

[0035] When it is necessary to cap different types of paint cans, the worker only needs to pull the pull ring outside the positioning rod 17 to pull out the positioning rod 17, so that the positioning rod 17 is disengaged from the inside of the positioning hole 15. At this time, the locking between the mounting shaft 14 and the mounting shell 13 is disengaged. At this time, the worker holds the bottom of the capping head 16 with one hand to continue to pull the positioning rod 17 until it is completely received into the mounting shell 13. At this time, the clamping plate 20 will fall downward under the action of gravity and insert into the mounting shell 13 to block the end of the positioning rod 17, preventing the positioning rod 17 from resetting under the action of the spring 18. At this time, the capping head 16 and the mounting shaft 14 can be easily disassembled and replaced. Then, the mounting shaft 14 at the top of another type of capping head 16 is inserted into the mounting shell 13, and the clamping plate 20 is pushed upward to disengage it from the mounting shell 13. At this time, the compressed spring 18 is reset to push the stopper 19 to drive the positioning rod 17 to reset, and then the positioning rod 17 is inserted into the positioning hole 15 of another type of capping head 16, so that the replacement of the capping head 16 can be completed quickly and conveniently, reducing the time required for replacing different types of capping heads 16.
