Referring to fig. 3, for the utility model discloses an embroidery machine tabouret, including fixed frame 15, cloth fixing device 2 and cloth height positioner 7, cloth fixing device 2 includes clamp plate 3, tucking 4 and actuating mechanism 5, and actuating mechanism 5 is including driving actuating cylinder.

As shown in fig. 3, the fixing frame 15 is formed with a fixing groove 16 extending in a longitudinal direction of the fixing frame 15, and one side of the fixing groove 16 penetrates a side wall of the fixing frame 15 toward a center area of the embroidery frame so that a cross section of the fixing frame 15 is stepped.

Drive actuating cylinder and install on fixed frame 15 and be located fixed slot 16 one side back to tabouret central zone, the piston rod that drives actuating cylinder sets up towards the tabouret is inside, the end of the piston rod portion that drives actuating cylinder articulates there is connecting rod 51, connecting rod 51 keeps away from the one end of piston rod and is articulated with clamp plate 3, clamp plate 3 articulates on fixed frame 15 and articulated position is located fixed slot 16 and drive between the actuating cylinder, form the compress mouth between clamp plate 3 and the fixed slot 16, the piston rod that drives actuating cylinder is articulated with clamp plate 3 surface to fixed slot 16 back to in order to drive clamp plate 3 and be close to or keep away from fixed slot 16 and rotate when.

As shown in fig. 3 and 4, a pressing strip 41 is fixed on the surface of the pressing plate 3 facing the fixing groove 16, the length direction of the pressing strip 41 is parallel to the fixing groove 16, pinholes 42 distributed along the length direction are formed on the surface of the pressing strip 41 facing the fixing groove 16, the needle tail of the pressing needle 4 is inserted into the pinholes 42, positioning holes 43 corresponding to the pinholes 42 in number and communicating the pinholes 42 are formed in the side surface of the pressing strip 41, positioning bolts 44 are connected to the positioning holes 43 in a threaded manner, and the bottom of a screw rod of each positioning bolt 44 extends into the pinhole 42 and abuts against the needle tail of the pressing needle 4, so that the pressing needle 4 is fixed on the pressing strip 41.

Set up the mounting groove 61 that extends along 6 length direction of fixed slot in the fixed slot 16, mounting groove 61 tank bottom bonding is fixed with flexible strip 6, and the upper surface of flexible strip 6 is higher than the fixed slot 6 surface, and flexible strip 6 includes rubber strip or foam adhesive tape, and when driving actuating cylinder and driving clamp plate 3 and rotate the fixed slot 16 top, layering 41 bottom surface and flexible strip 6 surface are contradicted, and tucking 4 passes the selvedge between layering 41 and the flexible strip 6 and pricks into in the flexible strip 6.

A convex strip 18 which protrudes upwards and is parallel to the length direction of the fixed groove 16 is fixed on the fixed groove 16, the cross section of the convex strip 18 is cylindrical, and the convex strip 18 is positioned on one side of the flexible strip 6, which is back to the driving cylinder. The surface of the convex strip 18 is integrally provided with an anti-slip convex rib 19 with the length direction parallel to the length direction of the convex strip 18 in a protruding manner, and the anti-slip convex rib 19 is provided with a plurality of strips which are distributed along the circumferential direction of the convex strip 18.

Cloth height positioner 7 includes spacing lug, spacing lug an organic whole sets up in clamp plate 3 bottom surface, spacing lug is located raised line 18 one side back to flexible strip 6, the bottom surface height of spacing lug is highly unanimous with the cloth cover that requires when embroidery machine embroiders, the height that highly is higher than spacing lug of raised line 18 to make the cloth stretch into the surface that can laminate raised line 18 behind the compress mouth, form crooked shape, again through between tucking 4 and flexible strip 6.

The height of the top surface of the flexible strip 6 is between the highest point of the convex strip 18 and the height of the bottom of the fixed groove 16, and the height of the bottom surface of the limiting convex block is lower than the height of the bottom of the fixed groove 16.

The implementation principle of the embodiment is as follows: during the use, draw in the compress mouth earlier with the selvedge, draw in the in-process, the selvedge is earlier with the below of following spacing lug and walk around, then gets into from the clearance between spacing lug and the fixed slot 16, and the protrusion 18 of bypassing, gets into the compress mouth along protrusion 18 surface again to along with the top of the effect process flexible strip 6 of granny rag. When the cloth is tensioned, the surface of the cloth below the limiting convex block is abutted against the bottom surface of the limiting convex block, so that the height of the cloth in the embroidery area is the same as the height of the cloth required by embroidery.

Then the driving cylinder is started, the piston rod of the driving cylinder moves to drive the pressing plate 3 to rotate around the hinge, the cloth pressing opening is gradually reduced during rotation, and the pressing needle 4 penetrates through the cloth edge and is pricked into the flexible strip 6 to complete the fixing work of the cloth.

And then embroidery is performed.

When the pressing pin 4 on the pressing bar 41 is damaged, the pressing pin 4 is pulled out from the needle hole 42 after the positioning bolt 44 is unscrewed, then a new pressing pin 4 is replaced, and then the positioning bolt 44 is screwed down, so that the replacement of the pressing pin 4 can be completed.

An embroidery machine comprises an embroidery frame of the embroidery machine. When the cloth clamping device is used, the complicated cloth clamping process and the higher labor intensity can be avoided, so that the cloth clamping process of workers is simpler and more convenient, and the cloth clamping effect is good.

Example 2: as shown in fig. 5, the embodiment 2 is different from the embodiment 1 only in that in the embodiment 2, the presser pin 4 is fixed on the surface of the fixed frame 15 through the presser bar 41, the flexible strip 6 is adhered to the bottom of the pressing plate 3, when the pressing plate 3 is driven to rotate by the driving cylinder, the flexible strip 6 rotates along with the pressing plate 3 and causes the presser pin 4 to penetrate through the cloth and then penetrate upwards into the flexible strip 6, and when the cloth is pressed, the height of the bottom surface of the flexible strip 6 is between the highest point of the convex strip 18 and the height of the bottom of the fixed groove 16.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
