For the problems referred to above, the utility model proposes a kind of novel cloth feeding mechanism.
The utility model content:
The purpose of this utility model is to overcome the prior art weak point, and a kind of novel cloth feeding mechanism is provided.
The utility model realizes that the technical scheme that its purpose adopts is: a kind of novel cloth feeding mechanism comprises: one is installed on tooth seat, on the body is installed on retainer on the tooth seat, and a tooth lifting cam is installed on this retainer; One is installed on the feed dog on the retainer, on the described tooth seat left and right regulating block is installed, and a guide plate is installed between left and right regulating block, and this left and right regulating block has the spigot surface that the guiding guide plate slides up and down; Described retainer is installed on the tooth seat by guide plate; Set up a wear plate between described tooth lifting cam and the retainer.
Furthermore, in the technique scheme, establish a concave surface on the described tooth seat; Described left and right regulating block is installed on this concave surface, fixes by the regulating block screw.
Furthermore, in the technique scheme, described guide plate is stuck between the left and right regulating block, and has the inclined plane that cooperates with spigot surface.
Furthermore, in the technique scheme, described retainer comprises a main board and takes shape in the installing plate that one of main board lower end has installing port; Described tooth lifting cam is installed in the installing port, sets up described wear plate between tooth lifting cam top and installing plate.
Furthermore, in the technique scheme, described main board and guide plate are fixed by a guider screw; Fix by the wear plate hold-down screw between described wear plate and the installing plate.
Furthermore, in the technique scheme, described tooth lifting cam two ends are provided with the left and right sides catch that prevents tooth lifting cam left and right sides play.
Furthermore, in the technique scheme, the main board of described feed dog and retainer is by feed dog screw fixed installation.
After the utility model adopts said structure, compared with prior art have following beneficial effect:
1, the utility model is equipped with left and right regulating block at the tooth seat, the part spigot surface is had in the situation of wearing and tearing, adjust simultaneously the left and right regulating block of both sides, guaranteed that retainer is in the position at tooth seat center forever, prevent the phenomenon of retainer off-centre, thereby guaranteed well the precision of cloth feeding mechanism.
2, the utility model only needs the left and right regulating block of replacing or guide plate to get final product owing to making spigot surface that very large wearing and tearing be arranged for a long time this moment, need not change retainer, saves cost.
3, left and right sides catch is widened and increased to its tooth lifting cam of the utility model, makes like this mechanism's duty more steady and can effectively prevent tooth lifting cam left and right sides play, thereby reduced the generation of the bad phenomenon such as the machine generation broken needle, wire jumper.
4, the utility model is installed a wear plate at retainer, can effectively reduce the tooth lifting cam rotation to the wearing and tearing of retainer, and after the wear plate wearing and tearing, its reverse side is installed continuation to be used, behind two surface wears, only need to change to get final product with wear plate, can effectively reduce cost of parts like this.

The specific embodiment:
Below in conjunction with specific embodiments and the drawings the utility model is further specified.
See Fig. 1-4, a kind of novel cloth feeding mechanism comprises: one is installed on tooth seat 1, on the body is installed on retainer 2 on the tooth seat 1, and a tooth lifting cam 6 is installed on this retainer 2; One is installed on the feed dog 7 on the retainer 2, and left and right regulating block 3,4 is installed on the described tooth seat 1, and a guide plate 5 is installed between left and right regulating block 3,4, and this left and right regulating block 3,4 has the spigot surface that guiding guide plate 5 slides up and down; Described retainer 2 is installed on the tooth seat 1 by guide plate 5; Set up a wear plate 8 between described tooth lifting cam 6 and the retainer 2.
Particularly, described tooth seat 1 both sides offer screw, are installed on the body by attachment screw 11.Establish a concave surface on the tooth seat 1, on concave surface, offer screw.Offer microscler screw on the left and right regulating block 3,4; Guide plate 5 is stuck between the left and right regulating block 3,4, and the two sides of guide plate 5 are the inclined plane that cooperates with spigot surface.Described retainer 2 comprises a main board 21 and takes shape in the installing plate 22 that one of main board 21 lower ends have installing port; Tooth lifting cam 6 is installed in the installing port, sets up described wear plate 8 between tooth lifting cam 6 tops and installing plate 22, and is fixing by hold-down screw 81 between wear plate 8 and the installing plate 22.Tooth lifting cam 6 is installed by trip bolt 63 and body.Described tooth lifting cam 6 both end sides have the left and right sides catch 61,62 that prevents tooth lifting cam 6 left and right sides plaies.
During installation, left and right regulating block 3,4 is installed on the tooth seat 1 and is affixed with concave surface, by regulating block screw 31,41 and tooth seat 1 fixing; Guide plate 5 inserts between the left and right adjustable plate 3,4.Then main board 21 is installed on the guide plate 5, by a guider screw 51 both is fixed; At last feed dog 7 and the main board 21 of retainer 2 are fixedly finished installation by a feed dog screw 71.
The utility model in use, tooth lifting cam 6 is activated, tooth lifting cam 6 High Rotation Speeds drive retainer 2 motions, then drive guide plate 5 and feed dog 7 motions, because guide plate 5 is stuck between the left and right regulating block 3,4, can only slide up and down along spigot surface by left and right regulating block 3,4 restricted guidance plates 5, therefore determine the movement locus of feed dog 7, namely feed dog 7 can move up and down under the drive of tooth lifting cam 6.When tooth lifting cam 6 rotated, its left and right catch 61,62 had prevented tooth lifting cam 6 left and right sides plaies effectively.
