Abstract
The utility model relates to a rolling wheel type rapier opening mechanism of a rapier loom, comprising a rolling bearing (1), a sleeve gasket (2), a rapier opening seat (3), a screw (4), a guide rail (5), a left rapier head (6), a rapier opening block (7), a yarn clipping reed (8) and a yarn clipping block (9); wherein, the rolling bearing (1) and the sleeve gasket (2) are arranged on the rapier opening seat (3) through the screw (4); the rapier opening seat (3) is positioned on the guide rail (5); the rapier opening block (7), the yarn clipping reed (8) and the yarn clipping block (9) are arranged on the left rapier head (6) which is connected with the guide rail (5) in a sliding way; when the left rapier head 6 makes return movements along the guide rail 5, the rapier opening block 7 touches the rolling bearing 1, and the rolling bearing 1 screws down the rapier opening block 7 to drive the yarn clipping reed 8 to move downward so as to open the rapier head. The rolling wheel type rapier opening mechanism can ensure the accurate opening amount of the rapier head with little operation resistance and solves the wear problem of the rapier opening device of a high-speed rapier loom.
Description
Technical field
The utility model belongs to Rapier looms, is 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 problems to be solved in the utility model 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.
The technical solution of the utility model: 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 utility model 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 utility model is compared with prior art: 1. rolling bearing can accurately be located, guarantee sword head open amount accurately, guarantee that the efficient operation of loom 2. rolling bearings are not easy to wear, long service life 3. rolling bearings are rolling movements with opening the sword piece, running resistance is little, can prolong sword belt service life.Design of the present utility model 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.
