Detailed Description

The following describes a specific embodiment of the present embodiment with reference to the drawings.

Fig. 1 is a schematic view of a partial structure of the present invention. Fig. 2 is a partial front view of the present invention. Referring to fig. 1 and 2, the present invention discloses a combined chain for a paint dripping machine. The direction of X in the figure does the utility model discloses local structure schematic's front end, the direction of Y in the figure does the utility model discloses local structure schematic's right-hand member. A combination chain for a paint dripping machine comprises: outer link joint 1, sleeve 2 and round pin axle 6.

The outer chain plates 1 are arranged at two ends of the sleeve 2. An oilless bearing 4 is arranged in the sleeve 2, and a first roller 3 is arranged outside the sleeve 2. An inner chain plate 5 is arranged between the adjacent outer chain plates 1. The pin shaft 6 is respectively connected with the outer chain plate 1 and the inner chain plate 5. A second roller 7 is arranged outside the pin 6.

The sleeve 2 is symmetrically provided with first bosses 21 at both ends. The first boss 21 is embedded in the outer link plate 1.

Preferably, the sleeve 2 is cylindrical. The first bosses 21 are symmetrically provided at front and rear ends of the sleeve 2. The sleeve 2 is horizontally arranged in the front-back direction. Preferably, the first boss 21 is cylindrical. The diameter of the sleeve 2 is larger than the diameter of the first boss 21. The front surface of the first boss 21 is provided with a first through hole. The first through hole penetrates the first boss 21 and the sleeve 2.

The outer chain plates 1 are symmetrically arranged at the front end and the rear end of the sleeve 2. The outer surface of the first boss 21 is embedded in the outer link plate 1. The end surface of the sleeve 2 is pressed against the inner side surface of the outer chain plate 1.

Preferably, the outer link plate 1 is rhombic. And the corners of the outer chain plate 1 are subjected to fillet treatment.

The rhombus outer chain plate 1 is compared with the straight edge chain plate, so that the waste of materials is avoided. The rhombic outer chain plate 1 reduces the space occupation, and the combined chain for the paint dripping machine can be more conveniently arranged on the paint dripping machine. The fillet processing's outer chain plate 1 has avoided outer chain plate 1 scratch paint dripping machine.

A second boss 22 for restricting the movement of the oilless bearing 4 is provided in the sleeve 2.

The second boss 22 is disposed in the first through hole. The second boss 22 is provided at the rear end of the first through-hole. Preferably, the second boss 22 is an annular boss. The outer surface of the second boss 22 contacts the first through hole.

The oilless bearing 4 is embedded in the sleeve 2 from the front end of the sleeve 2. The rear end of the oilless bearing 4 contacts the front end of the second boss 22. The second boss 22 abuts against the oilless bearing 4. The second boss 22 restricts the oilless bearing 4 from continuing to move rearward in the first through hole.

Fig. 1 is a schematic view of a partial structure of the present invention. Fig. 3 is a cross-sectional view of the oilless bearing of the present invention. As shown in fig. 1 and 3, oil grooves 41 are formed in parallel on the inner surface of the oilless bearing 4. Preferably, the oil sump 41 has a diamond shape. The oil tank 41 is filled with solid grease. The oil sump 41 is used for storing solid grease. The solid grease facilitates rotation of the rotating shaft.

The choice of the type of oilless bearing 4 is common knowledge. Those skilled in the art can select the type of oil-free bearing SF-1, for example, according to the working condition of the device.

When the combined chain for the paint dripping machine is installed on the paint dripping machine, the rotating shaft on the paint dripping machine is inserted into the oilless bearing 4. The outer surface of the rotating shaft is attached to the inner surface of the oilless bearing 4.

The rotation shaft is inserted into the oilless bearing 4 from the front end of the oilless bearing 4. After the rotation shaft is inserted into the oilless bearing 4, the rotation shaft restricts the forward movement of the oilless bearing 4. The second boss 22 and the rotation shaft ensure that the oilless bearing 4 does not undergo positional deviation in operation.

When the paint dripping machine works, the rotating shaft rotates in the first through hole through the oilless bearing 4. The rotation axis can carry out the plug fast in oilless bearing 4, and oilless bearing 4 has guaranteed the rotation that the rotation axis can be smooth and easy.

The oilless bearing 4 avoids the phenomenon that the rotating shaft bites. In order to ensure that the rotating shaft can rotate smoothly, a gap is reserved between the rotating shaft and the sleeve 2. When the rotation shaft rotates, the rotation shaft and the sleeve 2 generate friction, which generates noise. The clearance between the rotation shaft and the sleeve 2 is eliminated by the oilless bearing 4. The rotating shaft is inserted into the oilless bearing 4, and the solid lubricating grease ensures that the rotating shaft can rotate smoothly, so that the noise generated when the rotating shaft rotates is reduced.

Preferably, the first roller 3 is cylindrical. The first rollers 3 are horizontally arranged in the front-rear direction. The front surface of the first roller 3 is provided with a second through hole. The outer surface of the sleeve 2 passes through the first roller 3. The sleeve 2 is placed in the second through hole.

The inner chain plate 5 is connected with the outer chain plate 1 through a pin shaft 6. Preferably, the pin 6 is cylindrical. The pin shaft 6 is horizontally arranged in the front-back direction. The pin shaft 6 respectively penetrates through the outer chain plate 1 and the inner chain plate 5. The outside surface of the inner link plate 5 is fitted to the inside surface of the inner link plate 5.

The pin shaft 6 is also provided with a second roller 7. Preferably, the second roller 7 is cylindrical. The second rollers 7 are horizontally installed in the front-rear direction. The front surface of the second roller 7 is provided with a third through hole. The outer surface of the pin 6 passes through the second roller 7. The pin shaft 6 is arranged in the third through hole. The second roller 7 is located inside the inner link plate 5. The second roller 7 rotates along the outer surface of the pin 6. The pin shaft 6 ensures that the inner chain plate 5 and the outer chain plate 1 can be stably connected.

In the present embodiment, the second boss 22 is described as an annular boss, but the present invention is not limited thereto, and may be a boss having another shape within a range capable of functioning.

In the present embodiment, the inner link plates 5 are described as being straight plates, but the present invention is not limited thereto, and may be inner link plates having other shapes within a range where the function thereof can be exerted.
