BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a cloth pin tenter, which eliminates the need for supplying lubricating oil to sliding parts of a tenter rail and a pin chain.

[0002]

2. Description of the Related Art As a cloth pin tenter, a roller chain type pin chain running along a tenter rail is known. For example, Jitsuko Sho 54-2
In Japanese Patent No. 5517, a bush and a roller are sequentially fitted to a large number of vertically connecting pins, and upper and lower ends of the two bushes are intermediate links, and lower protruding ends of the two connecting pins are lower. The bottom of the rail groove where the upper end of the upper link is fixed with the pin plate support plate, and the lower surface of the lower link is attached to the tenter rail by connecting the upper protruding end with the link In addition, the vertical part of the upper link slides on the groove of the rail groove, and the end of the horizontal part of the upper link slides on the lower surface of the upper guide plate provided above the center of the tenter rail. It is disclosed.

[0003]

However, in the pin tenter described above, oil passages are provided in the groove wall of the rail groove and the upper guide plate to lubricate the sliding surfaces, and the upper link and the upper intermediate link are respectively provided. Since the oil groove and the oil hole for supplying oil were provided in the fitting portion of the connecting pin and the bush, it is difficult to supply an appropriate amount of lubricating oil according to the temperature in the chamber of the tenter and the fabric speed. There is a problem in that excess or deficiency is likely to occur, and therefore excess causes soiling of the fabric due to scattering of lubricating oil, or insufficient wear of the sliding surface.

This invention eliminates the need for supplying lubricating oil and prevents the cloth from being contaminated by the scattering of lubricating oil and the sliding surface from being worn due to insufficient lubrication.

[0005]

A cloth pin tenter according to the present invention is a pin chain provided on a bottom surface of a rail groove provided on a tenter rail, a groove wall on a side where the pin chain slides, and a central portion of the tenter rail. Heat-resistant and wear-resistant liners are fixed to the lower surface of the upper guide plate where the ends of the upper links slide, and the heat resistance is secured to the bushes that connect the upper and lower intermediate links of the pin chain that runs along the rail groove. The inner ring of the heat-resistant shield type ball bearing is fixed, and the outer ring is brought into contact with the heat resistant and abrasion resistant liner fixed to the groove wall of the rail groove.

[0006]

[Function] Wrap the pin chains between the sprockets at both ends so that the heat-resistant shield type ball bearings of the pin chains mesh with the teeth of the sprockets provided at both ends of the tenter rail, and the intermediate part other than both ends of the pin chain is tentered. When the pin chain is inserted by inserting it into the rail groove of the rail and engaging the ears of the fabric with the pins on the pin plate and running the pin chain, the lower link of the pin chain contacts the heat resistant and abrasion resistant liner on the bottom of the rail groove and slides. In addition, the outer ring of the heat resistant shield type ball bearing rolls by pressing against the heat resistant and wear resistant liner on the groove wall of the rail groove, and the end of the upper link contacts the heat resistant and wear resistant liner on the lower surface of the upper guide plate. Slide.

In this case, since the lower link of the pin chain, the outer ring of the ball bearing and the end of the upper link are all in contact with the heat resistant and abrasion resistant liner, the lower link, the ball bearing and the upper link are worn even if oil is not supplied. The heat-resistant crease is filled only between the inner ring and the outer ring of the ball bearing, which enables long-term oil-free operation. When the above heat and abrasion resistant liner is worn, only the liner can be replaced. Since the outer ring of the ball bearing comes into contact with the heat resistant and wear resistant liner on the groove wall of the rail groove due to the action of fabric tension, a larger pressure is applied than the heat resistant and wear resistant liner of the bottom of the rail groove and the upper guide plate. However, since the ball bearing rolls, its wear is small.

EXAMPLE In FIG. 2, 10 is a tenter rail and 11 is a tenter rail.
Is a rail groove on the conveying side, and an upper guide plate 12 is provided above the center in the width direction (to the left in the figure).
A rail groove (not shown) on the return side is provided on the opposite side of the rail. Then, on the bottom surface of the rail groove 11, the outer groove wall, and the lower surface of the upper guide plate 12, a heat-resistant and abrasion-resistant liner containing a phenolic thermosetting resin as a main component (trade name "Hightem S", Starlight Industrial Co., Ltd. (Made by company) 13, 14 and 15 are fixed.

In the pin chain 20 running along the rail groove 11 (see FIGS. 1 and 2), a bush 22 shorter than the connecting pin 21 is rotatably fitted to a vertically connecting pin 21. An inner ring of a heat-resistant shield type ball bearing 23 is fixed to the center of the bush 22, and a connecting pin 21 having a large number of the bushes 22 is connected to a pair of upper and lower intermediate links 24, which connects the bushes 22 at both ends. 24
And a lower link 25 connecting two connecting pins 21 at the lower protruding end and an upper link 26 connecting at the upper protruding end.
They are formed by alternately connecting and.

The lower link 25 has a length that extends between the ends of two adjacent lower intermediate links 24, 24, and is formed in a narrow plate shape that slides on the bottom liner 13 of the rail groove 11. To be done. Further, the upper link 26 has a length spanning between the ends of two adjacent upper intermediate links 24, 24, and a width extending from above the upper intermediate link 24 to the upper liner 15 fixed to the upper guide plate 12. Bolt part 2 formed on the upper end of the connecting pin 21
A pin 28 and a pin plate supporting plate 27 are tightened and fixed to the la 1a. Then, the pin plate 29 is fixed to the pin plate support plate 27.

In the above structure, when the ears of the cloth F are locked to the pins of the pin plate 29 and the pin chain 20 is run, the lower surface of the lower link 25 of the pin chain 20 and the upper surface end of the upper link 26 are separated. The bottom liner 13 of the rail groove 11 and the upper liner 15 of the upper guide plate 12 respectively
The heat-resistant shield type ball bearing 23, which slides along the rail and is attached to the connecting pin 21 via the bush 22, rolls along the groove wall liner 14 of the rail groove 11.

[0012]

As described above, the pin tenter of the present invention has a heat resistant and wear resistant liner fixed to the bottom surface of the rail groove of the tenter rail, the groove wall on one side and the lower surface of the upper guide plate, respectively, and the bush is heat resistant. Since the inner ring of the shield type ball bearing is fixed and the outer ring is brought into contact with the heat resistant and abrasion resistant liner fixed to the groove wall of the rail groove,
By filling the heat-resistant shield type ball bearings with heat-resistant crease, it is possible to continue operation for a long time without refueling, and there is no oil splash due to excessive refueling. The lower link, heat-resistant shielded ball bearing and upper link of the pin chain that come into contact with it will not be worn. When the heat resistant and abrasion resistant liner of the bottom surface of the rail groove, the groove wall and the upper guide plate is worn, it is sufficient to replace only the liner, and it is not necessary to replace the tenter rail. Further, since the outer ring of the ball bearing comes into contact with the liner of the groove wall to which the greatest pressure is applied among the bottom surface of the rail groove, the groove wall and the upper guide plate, the liner is less worn.
