Manufacturing method of novel hand mold base for nitrile glove production line

- Oct 22, 2020-

Background technique:


Nitrile gloves are our hand protection and safety disposable tools, as well as one of our daily supplies. In the mass production of nitrile gloves, a complete set of production equipment is inevitably needed. The production equipment cannot be separated from the glove mold, also called the hand mold. The hand mold is a necessary condition for glove production. The quality and structure of the hand mold base are good or bad. Determines the cost of glove production. The hand mold holders currently used in the market basically have a base, a spring, a bending arm and a bearing.


However, the existing hand mold seat design still has shortcomings. The bearings are all combined. The structure is single-point support. The single-point support has poor control of the left and right swing of the hand mold. It is also easy to quickly wear the bearings and cause bending. When the arm swings, the hand mold swings from side to side during the production process, which can easily cause hand mold fights, collisions with gloves, and a large amount of waste products, which is not conducive to reducing the defective rate. Moreover, the bearing chamber and spring do not have a closed protection mechanism, which is easy to adhere to dust or enter The corrosive gas produces sludge and the falling sludge contaminates the product. For this reason, a new type of hand mold holder for the nitrile glove production line is proposed to solve the above problems.

Technical realization elements:


The purpose of the utility model is to solve the shortcomings existing in the prior art, and proposes a new type of hand mold base for the nitrile glove production line.


In order to achieve the above objective, the present invention adopts the following technical solution: a new type of hand mold base for the nitrile glove production line, including a hand mold base on which a seat rod is slidably mounted, and the bottom of the hand mold base is provided There are quincunx card holders and nuts. The top of the hand mold base is fixedly installed with a sub-disc. The upper rotating sleeve of the seat post is provided with a bearing chamber with an opening at the bottom. One side of the bearing chamber is fixedly installed with an l-shaped arm and a l-shaped bending A curved arm sleeve is fixedly installed on the top of the arm, an oil hole is opened on the curved arm sleeve, two bearings are fixedly installed in the bearing chamber, and the inner rings of the two bearings are sliding sleeves on the seat post, and the seat post is fixedly installed with A circlip, the lower bearing is matched with the first circlip, the sliding sleeve on the seat post is provided with a top tube, the top and bottom ends of the top tube respectively contact the inner ring of the corresponding bearing, and the lower seal is fixedly installed in the bearing chamber The two bearings are located above the lower sealing ring. The top of the lower sealing ring is in contact with the outer ring of the corresponding bearing. The top inner wall of the bearing chamber is provided with a first through hole, and the top of the seat post penetrates through the first through hole. An upper sealing ring is provided on the seat post, which is matched with the first through hole, and a second circlip is fixedly installed on the seat post. The second circlip is in contact with the top of the upper sealing ring, and the seat post has a fixed sleeve It is provided with a top bowl with an opening at the bottom, a groove is provided on the top of the auxiliary tray, a pipe is fixedly installed on the inner wall of the bottom of the groove, the top of the pipe extends into the top bowl, and the bottom of the top bowl extends into the groove, and The top bowl is slidably connected with the inner wall of the groove, the seat post penetrates the guide tube and is slidably connected to the inner wall of the guide tube, the guide tube and the seat post are provided with the same spring in the sliding sleeve, the bottom of the spring contacts the bottom inner wall of the groove, and the top of the spring In contact with the top inner wall of the top bowl, the top of the top bowl extends into the bearing chamber and contacts the bottom of the first circlip. The third circlip is fixedly installed on the top bowl, and the third circlip is in contact with the bottom of the lower sealing ring. The sealing ring is rotated and sleeved on the top bowl.


Compared with the prior art, the beneficial effects of this utility model are:


(1) By opening the groove, the spring can be penetrated into the base of the hand mold to meet the requirement of 3cmm between the two bearings, thus changing the single support point to double support point, which greatly slows down the wear speed of the bearing and increases l The stability of the curved arm effectively reduces shaking and improves the yield;


(2) By adding a sealing ring to the bearing chamber, it is avoided that dust and corrosive gases enter the bearing chamber and react with the lubricating grease of the bearing to produce colloidal substances, ensuring the smooth rotation of the bearing, and adding a top bowl to the spring. It can effectively prevent dust from adhering to produce sludge and reduce the pollution of products by sludge.


The utility model has a reasonable structure, improves the stability of the hand mold base, avoids the shaking of the hand mold base, extends the service life, improves the production efficiency, reduces the maintenance cost in the later stage, reduces the defective product rate, and is more suitable for large-scale Nitrile glove production line.
