Abstract
The utility model relates to a needle foot alternative roller guide rail for a double-needle integrated feeding flat seamer. A guide rail is in plate shape. The utility model is characterized in that a guide rail plate (9) is arranged on a plane which is arranged on a machine head body near a roller (10) in a face mask plate by screws; the roller (10) contacts the side edge of the guide rail plate (9). The utility model can be used for installing the face mask plate after visually regulating the gap between the guide rail plate and the roller, can improve the installation speed and the assembly precision and prolong the service life of external pressure foot rods.
Description
Technical field:
The utility model relates to Sewing machines, and the comprehensive feeding flat seam machine of particularly a kind of crosspointer replaces the roller guide device with presser feet.
Background technology:
Usually the comprehensive feeding flat seam machine of crosspointer is interior presser feet 1 and shank 2 and feed dog while work feed, and this moment, outer presser feet 3 lifted.After work feed was finished, outer presser feet 3 falls pushed down sewing, and interior presser feet 1 and shank 2 lift and leave sewing, as shown in Figure 1 and Figure 2.This moment, connecting rod 4 pulling cranks 5 rotated around axle 6, give moment of torsion of outer presser bar, and this moment of torsion can produce resistance to machine run, enhance faster wear.In order to eliminate this moment of torsion, normally mask plate is divided into two 7 and 8, to design a guide rail plate 9 and be screwed inner face at cover plate 7, contact guide rail plate side rolls and eliminates moment of torsion when allowing roller 10 on the axle 6 move up and down.But cannot see its back when problem is installed surface cover plate 7, whether roller 10 contacts good with guide rail 9, can't know also and can't regulate, and the gap is big can collision to produce noise, and enhance faster wear is too tightly understood in contact.
Summary of the invention:
The purpose of this utility model provides a kind of energy mounting guide rail directly perceived and the convenient comprehensive feeding flat seam machine of crosspointer of regulating replaces the roller guide device with presser feet.
The described in the utility model kind of comprehensive feeding flat seam machine of crosspointer replaces the roller guide device with presser feet, guide rail is plate shape, it is characterized in that this guide rail plate is installed on the plane that the close roller position of head processes in the cover plate with screw, roller contacts with guide rail plate side.
The guide rail plate can be folded into L shaped.The screw hole of guide rail plate is made counterbore shape.
The utility model is owing to directly be installed in the guide rail plate near crosshead body position in the roller cover plate with screw, earlier the guide rail plate is installed, can intuitively regulate the gap between guide rail plate and the roller, again mask plate is installed, improve installation rate and assembly precision, prolong the service life of outer presser bar.And mask plate need not to be divided into two, makes profile more neat and artistic.
Description of drawings:
Fig. 1 needs improved station diagram for prior art.
Fig. 2 is Fig. 1 position structural representation.
Fig. 3 is the utility model structural representation.
The specific embodiment:
With reference to Fig. 1,2, the prior art mask plate is divided into two 7 and 8, and guide rail plate 9 is screwed the inner face at cover plate 7.Presser feet in the mark 1-among the figure, 2-shank, the outer presser feet of 3-, 4-connecting rod, 5-crank, 6-crank axle, 7-mask plate, 8-mask plate, 9-guide rail plate, 10-roller.
With reference to Fig. 3, under the condition that satisfies intensity and installation, it is the smaller the better that guide rail plate 9 designs.Process a plane and two screws at head near roller 10 positions.The plane degree of depth is slightly larger than the thickness of guide rail plate 9, and the thickness of guide rail plate 9 approximates the twice of head of screw height, makes the mounting screw hole be designed to counterbore, and purpose is to allow guide rail and head of screw not exceed the panel installed surface.Prefabricated guide rail plate 9 is screwed in the plane, and roller 10 and guide rail plate 9 sides roll and contact, and roller situation about contacting with guide rail is very directly perceived like this.Under the situation of installing space permission, guide rail plate 9 is made L shaped (not drawing among the figure), can increase the contact-making surface of roller and guide rail plate.
Claims (3)
1, the comprehensive feeding flat seam machine of a kind of crosspointer replaces the roller guide device with presser feet, guide rail is plate shape, it is characterized in that this guide rail plate (9) is installed on the plane that the interior head of mask plate (7) processes near roller (10) position with screw, roller (10) contacts with guide rail plate (9) side.
2, presser feet according to claim 1 replaces the roller guide device, it is characterized in that guide rail plate (9) can be folded into L shaped.
3, presser feet according to claim 1 replaces the roller guide device, it is characterized in that the screw hole of guide rail plate (9) is made counterbore shape.
