Abstract
The invention relates to a roller type rapier forming mechanism of rapier loom, which comprises a rolling bearing (1), a separate sleeve (2), a rapier forming base (3), screws (4), guide rails (5), a left rapier head (6), a rapier forming block (7), yarn clamping reeds (8), and yarn clamping blocks (9), wherein the rolling bearing (1) and the separate sleeve (2) are arranged on the rapier formingbase (3) through the screws (4); the rapier forming base (3) is arranged on the guide rails (5); the rapier forming block (7), the yarn clamping reeds (8) and the yarn clamping blocks (9) are arranged on the left rapier head (6); and the left rapier head (6) is slidably connected with the guide rails (5). When the left rapier head (6) retracts along the guide rails (5), the rapier forming block (7) contacts the rolling bearing (1) and is compressed by the rolling bearing (1) to drive the yarn clamping reeds (8) to move downwards, so that the rapier head is opened. The rapier forming mechanismcan ensure accurate open amount of the rapier head and less motion resistance, and solve the abrasion problem of rapier former of high-speed rapier loom.
Description
Technical field
The invention belongs to Rapier looms, be specifically related to roller wheel type gripper opening mechanism of gripper loom.
Background technology
At present; the left sword of domestic and international Rapier looms is opened sword mechanism and is to use nylon block to open sword mostly; nylon block is installed in out on the sword seat; the sword head is opened the sword piece and is slipped under nylon block; be subjected to nylon block and press down, drive the yarn clipping reed and move downward, thereby the sword head is opened; so that air draught mouth cleaning sword head is weaved at a high speed.Its basic structure as shown in Figure 3 and Figure 4.
In Fig. 3,16-yarn clipping reed, 17-opens the sword piece, 18-yarn clipping piece
In Fig. 4,10-spacer, 11-are opened the sword seat, 12-screw, 13-left side sword head, 14-guide rail, 15-nylon block.
Zuo Jiantou send latitude to finish to do setback, when setback during near terminal point, on the sword head open the sword piece and nylon block is in contact with one another, the sword head is opened the sword piece and is slipped over from the nylon block lower surface, this motion belongs to sliding friction, and frictional resistance is big, and nylon block weares and teares easily, especially when the loom rotating speed was higher, the nylon block wearing and tearing were comparatively serious.Nylon block after the wearing and tearing can't press off the sword piece down, and sword head-clamp yarn mouth can not be opened, and the air draught mouth can't clean the sword head, causes latitude to stop frequently influencing weave quality.This class is driven the sword device and can not accurately be located, and wearing and tearing easily need often to adjust, and influence weave quality and efficient.
Summary of the invention
The technical problem to be solved in the present invention is to knit Zuo Jiantou and open the problem that exists in the sword process a kind of roller wheel type gripper opening mechanism of gripper loom is provided for overcoming high speed arrow shaft.
Technical scheme of the present invention: a kind of roller wheel type gripper opening mechanism of gripper loom; comprise rolling bearing 1, spacer 2, open sword seat 3, screw 4, guide rail 5, left sword head 6, drive sword piece 7, yarn clipping reed 8; yarn clipping piece 9; rolling bearing 1 and spacer 2 are arranged on out on the sword seat 3 by screw 4; opening sword seat 3 is arranged on again on the guide rail 5; open sword piece 7, yarn clipping reed 8, yarn clipping piece 9 and be arranged on the left sword head 6, left sword head 6 is slidingly connected with guide rail 5.
The present invention compared with prior art has following beneficial effect: replace nylon block to make out the sword device with rolling bearing, when sword head rollback during near terminal point, rolling bearing with open contacting of sword piece, the sword head continues rollback, rolling bearing is being opened the rolling of sword piece upper surface, simultaneously owing to open the ramp structure of sword piece, rolling bearing presses down opening the sword piece, driving the yarn clipping reed moves downward, thereby the yarn clipping jaw that sword head-clamp yarn piece and yarn clipping reed are formed is opened, be convenient to air draught mouth cleaning sword head, reduce latitude and stop number of times, improve weave quality.The present invention is compared with prior art: 1. rolling bearing can accurately be located, and guarantees sword head open amount accurately, guarantees that loom efficiently moves.2. rolling bearing is not easy to wear, long service life.3. rolling bearing is with to open the sword piece be rolling movement, and running resistance is little, can prolong sword belt service life.Design of the present invention has solved the wear problem that the sword device exists of opening of high speed Rapier looms.

The specific embodiment
A kind of roller wheel type gripper opening mechanism of gripper loom; comprise rolling bearing 1, spacer 2, open sword seat 3, screw 4, guide rail 5, left sword head 6, drive sword piece 7, yarn clipping reed 8; yarn clipping piece 9; rolling bearing 1 and spacer 2 are arranged on out on the sword seat 3 by screw 4; opening sword seat 3 is arranged on again on the guide rail 5; open sword piece 7, yarn clipping reed 8, yarn clipping piece 9 and be arranged on the left sword head 6, left sword head 6 is slidingly connected with guide rail 5.When left sword head 6 when guide rail 5 is made recoil movement, the sword piece 7 of opening that is installed on the sword head contacts with rolling bearing 1, rolling bearing 1 is depressed opening sword piece 7, drives yarn clipping reed 8 and moves downward, thereby the sword head is opened.
