Description

Technical Field

[0001] The utility model relates to the technical field of capping machines, and more specifically, to an automatic toothpaste capping machine. Background Art

[0002] An automatic toothpaste capping machine is a piece of automated machinery that automatically tightens the caps on toothpaste tubes to ensure the tubes are sealed and intact. This equipment is typically connected to a toothpaste production line, automating the entire process from production to packaging.

[0003] The existing publication number is CN218617305U. A toothpaste automatic capping machine is disclosed, specifically comprising a mounting base and a conveying mechanism. Two conveying mechanisms are disposed on the top of the mounting base. A tracking capping mechanism and a tracking capping mechanism are disposed on the top of the mounting base, located above the conveying mechanisms. The two conveying mechanisms are mirror-imaged and located on the front and rear sides of the mounting base. The conveying mechanisms include a mounting base. This automatic toothpaste capping machine utilizes two conveying mechanisms disposed on the top of the mounting base, with positioning slots defined on the exterior of the conveyor belts of the two conveying mechanisms. Two second servo motors drive the conveyor belts to rotate synchronously, placing toothpaste tubes on the platforms of the two conveyor belts and locking them into corresponding positioning slots to position the tubes. This ensures stable conveyance of flattened tubes and ensures precision during subsequent capping.

[0004] Existing automatic toothpaste capping machines are prone to slippage between the capping mechanism and the toothpaste cap, which can prevent the cap from being securely screwed onto the tube, compromising the seal. This poor seal can cause the toothpaste to dry out, deteriorate, or even become contaminated during use, impacting the product's effectiveness and safety. Slippage can also cause the capping mechanism to repeatedly re-tighten the cap, increasing production time for each product and reducing overall efficiency. To address this issue, we propose an automatic toothpaste capping machine. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides an automatic toothpaste capping machine, which has the advantage that the capping mechanism and the toothpaste cap are not prone to slipping.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 4 As shown, the utility model provides an automatic toothpaste capping machine, comprising a frame 1, a vertical shaft 2 being rotatably mounted on the frame 1, a plurality of storage slots 4 distributed in a circular array being arranged outside the vertical shaft 2, a connecting rod 3 being fixedly mounted on each of the storage slots 4, the ends of each of the storage slots 4 being fixedly connected to the vertical shaft 2, a capping mechanism being arranged at the upper end of the frame 1, and the capping mechanism being movable to the upper end of the storage slot 4. The screw capping mechanism includes an annular plate 5, which is arranged at the upper end of the storage slot 4. Two electric push rods 6 are fixedly installed at intervals on the frame 1. The output ends of the electric push rods 6 are fixedly connected to the annular plate 5. An annular member 7 is rotatably installed in the annular plate 5. The annular member 7 is hollow inside. A plurality of slide grooves 8 are provided on the inside of the annular member 7. A slider 9 is slidably provided in the slide groove 8. A non-slip pad is fixedly connected to one side of the slider 9. Two springs 10 are fixedly connected to the slider 9. The other end of the spring 10 is fixedly connected to the annular member 7. Two guide holes 11 are provided at intervals on the top of the annular member 7. The guide hole 11 is connected to the inner cavity of the annular member 7. A piston 12 is slidably provided in the guide hole 11. Two telescopic rods 13 are fixedly installed on the annular member 7. The output end of the telescopic rod 13 is fixedly connected to the piston 12.

[0022] The frame 1 is equipped with a rotating mechanism, which is connected to the vertical axis 2 and is used to drive the storage tank 4 to rotate about the vertical axis 2. The rotating mechanism includes a first motor 14, which is fixedly mounted on the frame 1, and the output shaft of the first motor 14 is fixedly connected to the vertical axis 2. A ring gear 15 is mounted on the outer surface of the annular member 7 and fixedly connected to it. A second motor 16 is fixedly mounted on the annular plate 5, and a driving wheel 17 is fixedly mounted on the output shaft end of the second motor 16, which meshes with the ring gear 15. The inner side of the annular member 7 is provided with anti-slip grooves. The frame 1 is provided with multiple threaded mounting holes.

[0023] The working principle and use process of this utility model:

[0024] By installing the frame 1 on an external capping machine, toothpaste is placed in the storage tank 4. The electric push rod 6 drives the annular plate 5 and the annular member 7 to be sleeved on the toothpaste cap. The telescopic rod 13 then drives the piston 12 downward, increasing the air pressure inside the annular member 7. As a result, one end of the slider 9 is pressed against the toothpaste cap, which increases the static friction between the annular member 7 and the toothpaste cap. Subsequently, the second motor 16 drives the driving wheel 17 to rotate, which drives the ring gear 15 to rotate, which in turn drives the annular member 7 to rotate. The annular member 7 then drives the toothpaste cap to rotate. Simultaneously, the electric push rod 6 drives the annular member 7 downward, completing the capping operation. The device is then reset, and the electric push rod 6 drives the annular member 7 upward to its original position. The first motor 14 then drives the vertical shaft 2 to rotate, causing the next storage tank 4 and the toothpaste therein to rotate to the lower end of the annular member 7.

[0025] The ring 7 fits snugly with the toothpaste cap, making it less likely to slip and more efficient. This ensures the cap is accurately and securely screwed onto the tube, effectively preventing the toothpaste from drying out, deteriorating, or becoming contaminated during use. This helps improve the product's effectiveness and safety.
