2. The dustproof chain of claim 1, wherein the free end of the convex plate is tilted to one side of the circumference of the upper end of the butterfly-shaped elastic sheet.

3. The dustproof chain of claim 1, wherein the raised plate has a plurality of grooves on both sides.

4. The dustproof chain of claim 1, wherein the gasket is a circular gasket.

Technical Field

The invention relates to the field of printing and dyeing, in particular to a dustproof chain.

Background

Patent No. CN208997263U discloses a dustproof chain, but in this patent dust can pile up at the bearing oil filling mouth department, and the accumulational dust can get into inside the bearing when filling grease, leads to high-speed operation to generate heat, card dead scheduling problem, influences bearing life. In addition, some special cloth materials can generate oily substances under the high-temperature working condition, and the oily substances enter the bearing to cause the overflow of high-temperature lubricating grease, so that the service life of the chain is influenced.

Disclosure of Invention

The invention aims to provide a four-footed mechanical wooden ox and flow horse with simulated gait.

The novel chain oil injection device has the innovation points that dust or oily substances can be effectively prevented from entering the bearing oil injection port, and the service life of the chain is prolonged.

In order to achieve the purpose, the technical scheme of the invention is as follows: a dustproof chain is composed of several chain units consisting of upper and lower plates, chain links consisting of upper and lower chain plates and bearing, and pin axle for linking said chain links with said chain seats, a sealing gasket is arranged between the bearing and the chain link lower chain sheet, the butterfly-shaped elastic sheet is of a hollow round table-shaped structure, the upper end of the butterfly-shaped elastic sheet is attached to the upper plate of the chain seat in a circumferential manner, the lower end of the butterfly-shaped elastic sheet is attached to the upper chain sheet of the chain link in a circumferential manner and completely covers the pin shaft hole on the upper chain sheet, the circumference of the lower end of the butterfly-shaped elastic sheet is provided with a convex plate, and a bulge inserted into the bearing oil injection port is arranged on the convex plate.

Furthermore, the free end part of the convex plate tilts towards one side of the circumference of the upper end of the butterfly-shaped elastic sheet. So that the bearing oil filling port is convenient to operate when being opened.

Furthermore, a plurality of grooves are formed in two sides of the convex plate. So that the convex plate of the butterfly-shaped elastic sheet is pushed by a tool to have a clamping point and is not easy to slip.

Further, the sealing gasket is a circular ring-shaped sealing gasket. And the loss of grease in the bearing is reduced.

The invention has the beneficial effects that:

1. the invention can effectively prevent dust or oily substances from entering the bearing oil injection port and prolong the service life of the chain.

2. The free end part of the convex plate tilts towards the upper plate of the chain seat, so that the bearing oil filling port is convenient to operate when being opened.

3. According to the butterfly-shaped elastic piece, the grooves are formed in the two sides of the convex plate, so that clamping points are formed when a tool is used for pushing the convex plate of the butterfly-shaped elastic piece, and the butterfly-shaped elastic piece is not easy to slip.
