Description

Technical Field

[0001] The utility model relates to the field of gallon bottle capping devices, in particular to a gallon bottle capping device. Background Art

[0002] Automatic capping devices are an essential component in the automation of liquid bottling equipment, such as those used for purified water, cooking oil, and cosmetics. These devices are crucial for unmanned, highly efficient production lines. With the continuous development of my country's industry, the output of high-purity chemical products is increasing, and product quality control is becoming increasingly stringent. For example, G5-grade high-purity acids and bases, photoresists, and stripping fluids are essential products for the semiconductor industry. With the increasing production volume of these products, efficient and fast automated production lines are also required. Currently, automated capping systems in the food and general chemical industries generally fall into two categories: the pneumatic gripper system, which clamps the bottle cap with a pneumatic gripper. A servo motor controls the speed, number of revolutions, and height of the rotation to achieve the capping action. The twisting capping system, on the other hand, uses a pneumatic cylinder to press four rubber wheels against the bottle cap. A motor then drives the wheels in both forward and reverse rotation, passively rotating the cap and automatically adjusting its height to open and twist the cap. The two current capping methods are relatively mature, but are limited to the food and general chemical industries. For the semiconductor, high-purity chemical, and photoresist industries, the current gallon bottle capping device has a considerable number of moving parts and exposed moving parts, which will drop a lot of particles and metal ions during operation. Therefore, a gallon bottle capping device is needed.

[0003] Existing gallon bottle capping devices, whether pneumatic gripping or twisting capping, have a significant number of moving parts and exposed moving parts during operation. This releases a significant number of particles and metal ions during operation, completely failing to meet the PPt (parts per trillion) standards required by the semiconductor industry. Furthermore, the semiconductor chemical industry often uses corrosive liquids, which emit various corrosive gases. When metal materials in existing devices come into contact with these materials, they can cause severe corrosion, potentially contaminating the liquid at best and shortening the life of the mechanism, leading to unexpected failures and potentially causing unforeseen losses. Therefore, a gallon bottle capping device is urgently needed. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a gallon bottle capping device to solve the problem that a lot of Particals, metal ions and materials do not meet the standards will fall off during the operation of the existing gallon bottle capping device.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a gallon bottle capping device, comprising a servo motor, wherein the output shaft of the servo motor is fixedly connected to a rotating rod via a coupling, a capping sleeve is installed on the outer wall of the rotating rod, a card slot is provided inside the capping sleeve, a card strip is installed inside the capping sleeve, and an O-ring is installed inside the capping sleeve.

[0006] A Teflon plastic layer is fixedly connected to the interior of the cap screwing sleeve.

[0007] Preferably, the capping sleeve forms a rotating structure through a rotating rod and a servo motor, and the capping sleeve is arranged in parallel with the servo motor.

[0008] Preferably, the clamping strip is arranged in a ring shape with the central axis of the cover screwing sleeve as the center, and the clamping strip is fixedly connected to the inner wall of the clamping groove.

[0009] Preferably, the O-ring is fixedly connected to the inner wall of the slot, and the O-ring is elastically arranged.

[0010] Preferably, the clamping strip and the O-ring are vertically distributed, and the rotating rod is fixedly connected to the cap screwing sleeve.

[0011] Preferably, the Teflon plastic layer is tightly fitted to the cap screw sleeve, and the Teflon plastic layer is embedded in the inner wall of the cap screw sleeve.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model is provided with a servo motor, a rotating rod, a capping sleeve, a clamping slot, a clamping strip and an O-ring. By moving the capping sleeve, the capping sleeve is sleeved on the outer wall of the bottle cap, driving the bottle cap to be clamped into the clamping slot, so that the clamping strip is matched with the clamping block on the bottle cap. Starting the servo motor can make the rotating rod rotate, drive the capping sleeve to rotate, so that the bottle cap is screwed off. At this time, the O-ring in the capping sleeve will hold the bottle cap tightly and fix it in the capping sleeve, which can prevent particles caused by mechanical transmission and other structures from falling into the bottle during the capping process. By replacing some moving parts with an ingenious mechanical mechanism, the cost is effectively reduced, the capping torque and the capping height are adjustable, and the application range of the structure is improved.

[0014] 2. The utility model provides a screw cap sleeve and a Teflon plastic layer, and the Teflon plastic layer is fixedly connected to the interior of the screw cap sleeve, so that the screw cap sleeve can withstand various corrosive gases and liquids, thereby solving the problem of raw material pollution from the material essence.
