Description

Technical Field

[0001] This utility model relates to a bottle cap picking, adjusting and sealing mechanism for a can sealing machine, and more particularly to a technical field that can automatically adjust the height and width of the container cap, accurately guide the container cap and the container can to align and engage, and further improve the sealing tightness of the cap through segmented pressing action. Background Technology

[0002] Existing can sealing machines typically transport beverage cans, food cans, or other metal containers to the sealing station via a conveyor belt, where a lid feeding mechanism provides the lid for sealing. However, in traditional structures, the lid is often transported to the can via a single path using a slide, lacking further angular guidance and positioning adjustment. This leads to lid misalignment, tilting, or jamming during the sealing process, reducing sealing efficiency and affecting sealing quality. Furthermore, existing lid feeding mechanisms are mostly limited to single-size lids. Changing to different sizes often requires altering the entire slide or replacing components, resulting in inconvenience and insufficient production line flexibility. Additionally, current pressing and sealing methods are mostly single-stage, where the lid is directly sealed by pressure applied by the pressure head. This method can easily cause excessive instantaneous force on the lid, leading to lid deformation or uneven sealing, failing to balance efficiency and sealing quality. Therefore, it is necessary to improve the design of a simple structure that is compatible with container caps of different sizes and has multi-stage guiding and phased pressing functions to ensure that the container cap can be sealed smoothly and accurately onto the container. Utility Model Content

[0003] This utility model is designed on the body of a can sealing machine. The machine body has a conveyor belt for transporting containers and is equipped with: a container lid feeding cylinder for holding multiple container lids, which are then sequentially output via an output slide and its internal guide rails; a container lid adjustment unit connected to the guide rails for adjusting the placement of the container lids; this unit includes a height adjustment module and a width adjustment module, allowing for flexible adjustment of height and width for container lids of different sizes, thus providing multi-specification compatibility; a container lid guiding unit connected to the container lid adjustment unit and corresponding to the conveyor belt position; through the first and second guide surfaces of its upper track, in conjunction with the front boxes and side rails on both sides, guiding the container lid to an appropriate angle before it enters the container, preventing offset or jamming, and ensuring precise alignment between the lid and the can; and a sealing and pressing unit connected to the container lid guiding unit, equipped with a first pressure rod and a second pressure rod. When the container lid is initially closed, the first pressure surface applies pressure at an inclined angle to form a preliminary position, and then the second pressure surface seals it fully at a horizontal angle. This achieves segmented pressing, avoids excessive instantaneous force on the container lid and deformation, and improves the sealing quality and reliability.

[0081] Please see Figures 1 to 13 The image shown is a preferred embodiment of the "bottle cap picking, adjusting and sealing mechanism of a can sealing machine" disclosed in this utility model. However, it should be noted that these embodiments are only for illustrating the technical features of this utility model and are not intended to limit the scope of implementation of this utility model. All embodiments that do not depart from the technical concept of this utility model should be included within the scope of protection of this utility model.

[0082] The bottle cap picking, adjusting, and sealing mechanism of this utility model can sealing machine mainly includes: a machine body A, a container cap feeding cylinder 10, a container cap adjusting unit 20, a container cap guiding unit 30, a sealing and pressing unit 40, and a conveyor belt 70. The conveyor belt 70 is set on the machine body A to carry and transport the container 50, so that its threaded opening end 51 can correspond to the position of the container cap feeding end.

[0083] A container cap feeding cylinder 10 is mounted on the machine body A, and its interior forms a feeding space 12 for accommodating multiple container caps 60. An output slide 11 is provided on one side of the container cap feeding cylinder 10, and a slide rail 13 is provided inside the output slide 11, allowing the container caps 60 to be sequentially discharged along the slide rail 13 and conveyed to the container cap adjusting unit 20.

[0084] A container lid adjustment unit 20 is mounted on the body A and connected to the slide rail 13. It includes a base 21 forming a track 211, and an upper cover 24 is mounted above the base. A height adjustment module 22 is provided between the base 21 and the upper cover 24 to adjust the height distance between them to accommodate container lids 60 of different thicknesses.

[0085] In this embodiment, the height adjustment module 22 includes a height adjustment knob 221, which can drive the first bevel gear 222 to rotate. The first bevel gear 222 meshes with and drives the second bevel gear 223, thereby driving the two longitudinal gear rods 23 to make the upper cover 24 move vertically up and down.

[0086] In addition, the base 21 has a width adjustment module 25 inside the track 211 to adjust the width of the track 211 to accommodate container lids 60 with different outer diameters.

[0087] The width adjustment module 25 includes a width adjustment knob 251, which can drive a forward and reverse screw 253. The two ends of the screw 253 respectively drive the slider 252 to move relative to each other, so that the slider 252 moves inward or outward, thereby achieving the inward or outward contraction of the track 211.

[0088] The container lid adjustment unit 20 has a set part 26 at one end for assembling the container lid guide unit 30. The container lid guide unit 20 has an adjustment hole 29 on one side, and an adjustment nut 28 is fixedly installed in the adjustment hole 29. The adjustment nut 28 can be fitted with an adjustment knob 27, which can be rotated to adjust the side rail assembly 39 of the container lid guide unit 30.

[0089] A container lid guiding unit 30 is mounted on the machine body A, corresponding to the conveyor belt 70, and connected to the container lid adjusting unit 20. The container lid guiding unit 30 includes a base component 31, one end of which forms an assembly end 32, which is assembled in the assembly part 26. An upper track 35 is connected to the base component 31, forming a first guide surface 351 and a second guide surface 352 to guide the container lid 60 smoothly into the threaded opening end 51 of the container tank 50. Track front boxes 36 are respectively provided on both sides of the upper track 35, each track front box 36 having multiple connecting holes 37 for selectively assembling the first guide rod 33 and the second guide rod 34. A locking part 38 is also provided on the track front box 36, which can accommodate the locking holes 392 of the side rail assembly 39, and a side rail part 391 protrudes from the bottom edge of the track front box 36 to enhance the positioning of the container lid 60.

[0090] In addition, one end of the container lid guide unit 30 is provided with a traction rod 303 and a traction rod spring 302, which can provide elastic reset function. A container lid track 304 is formed at its bottom to stably transport the container lid 60, and a guide port 301 is provided at the end for aligning with the threaded opening end 51 of the container 50.

[0091] A sealing and pressing unit 40 is provided on the machine body A, corresponding to the conveyor belt 70, and connected to the container lid guide unit 30. The sealing and pressing unit 40 includes a first pressing rod 41 and a second pressing rod 45. The bottom end of the first pressing rod 41 is provided with a first pressing seat 42, which is pivotally connected to the end of the first pressing rod 41 through a first pivot part 43, and the bottom of the first pressing seat forms a first pressing surface 44 with an inclination angle of 10 to 20 degrees. The bottom end of the second pressing rod 45 is provided with a second pressing seat 46, which is pivotally connected to the end of the second pressing rod 45 through a second pivot part 47, and the bottom of the second pressing seat 46 forms a second pressing surface 48 with a horizontal angle.

[0092] When container 50 is placed on conveyor belt 70 and passes through container lid guide unit 30, container lid 60 is aligned with threaded opening end 51 by guide port 301. Subsequently, the first pressing surface 44 and the second pressing surface 48 of sealing pressing unit 40 act sequentially to provide preliminary oblique pressing and final horizontal pressing, respectively, so that container lid 60 can be firmly screwed onto container 50, completing the sealing process.

[0093] A control unit C is configured inside the machine body A to control the opening and closing of the conveyor belt 70, adjust the speed of conveying multiple containers 50, and synchronously coordinate the supply, guidance and pressing of the container lids 60 to improve the overall automation efficiency.

[0094] The bottle cap picking, adjusting, and sealing mechanism of this invention's can sealing machine, through the height adjustment module 22 and the width adjustment module 25, can adapt to container caps 60 of different specifications; through the multi-guided design of the container cap guiding unit 30, it can ensure that the container cap 60 is accurately aligned with the threaded opening end 51 of the container can 50; and then the sealing and pressing unit 40 presses in stages, making the sealing process smooth and firm, effectively improving the efficiency and quality of automated can sealing.

[0095] Please see Figure 8 As shown, during the operation of the can sealing machine of this utility model, multiple containers 50 are conveyed forward in coordination with the operation of the conveyor belt 70, and multiple container caps 60 supplied simultaneously by the container cap supply cylinder 10 are guided by the output slide 11 and slide rail 13 and enter the container cap adjustment unit 20 in sequence. After adjustment and positioning, the container caps 60 then enter the container cap guiding unit 30 and correspond to the forward-moving container 50 on the conveyor belt 70 at the intersection position, so that each container cap 60 can be coupled and configured with the threaded opening end 51 of the corresponding container 50.

[0096] Please see Figure 9 As shown, when the container lid 60 enters the container lid guide unit 30 from the container lid adjustment unit 20, the first guide surface 351 of the upper track 35 is inclined, which can guide the container lid 60 at an angle, so that it is gradually pressed and formed into a configuration angle corresponding to the threaded opening end of the container can 50. At the same time, the second guide surface 352 of the upper track 35 connects with another container lid 60 that is about to enter, forming a continuous guide, so that the subsequent container lid 60 can complete the preparation state for the next configuration step.

[0097] Please see Figure 10As shown, when the container lid 60 enters the container lid guide unit 30, its two sides are supported and guided by the side rails 391 located at the bottom edge of the front rail box 36, preventing the container lid 60 from shifting during its forward movement. Furthermore, the upper surface of the container lid 60 is simultaneously supported and guided by the first guide surface 351 and the second guide surface 352 of the upper rail 35, thereby achieving comprehensive positioning of the upper end and periphery of the container lid 60. The user can also adjust the angle of the container lid guide unit 30 as needed to create a suitable tilt angle between the container lid 60 and the container 50, facilitating subsequent pressing and sealing.

[0098] Please see page 11 and... Figure 12 As shown, when the container lid 60 is already fitted onto the threaded opening end 51 of the container 50, initial pressing is first performed by the first pressing surface 44 of the sealing pressing unit 40. This first pressing surface 44 is at an inclined angle (approximately 10 to 20 degrees), allowing the container lid 60 to gradually press against the container 50 and complete the initial fixation. Subsequently, as the container lid 60 further enters the second pressing surface 48, the full pressing effect at a horizontal angle achieves a complete and stable seal between the container lid 60 and the container 50, thereby improving the reliability and sealing quality of the lid.

[0099] In summary, the structure of this utility model can effectively overcome the shortcomings of conventional models and further possess the numerous advantages and practical value mentioned above. Therefore, this utility model is a highly creative structure.
