Description

Technical Field

[0001] The utility model relates to the technical field of gold sheet embroidery, in particular to a driving mechanism for gold sheet embroidery. Background Art

[0002] The gold leaf embroidery feeding device includes a feeding mechanism and a slicing mechanism. The driving rod of the driving mechanism drives the cutter to slice through a series of connecting rod assemblies, and then uses a spring to drive the cutter to reset. The reset of the cutter needs to rely on a spring. The elastic force of the spring is fixed, and the reset speed is limited. As the needle speed of the machine continues to increase, the reset speed fixed by the spring cannot keep up with the needle speed of the machine, which is a bottleneck for increasing the machine speed. In particular, after the spring is pulled and used many times, the elastic force becomes worse and the reset effect becomes worse. Resetting the spring will cause problems such as inadequate slicing and affecting the feeding of the film. Utility Model Content

[0003] In order to solve the above problems of the prior art, the utility model provides a driving mechanism for a gold sheet cutter, which uses a driving rod and a reset spring to drive the cutter to reset. The cutter resets quickly, is efficient, and has a low slicing error rate.

[0004] The technical solutions adopted are as follows:

[0005] A driving mechanism for gold plate embroidery comprises a film feeding structure and a slicing structure arranged on a mounting seat, and also comprises a driving rod which drives a cutter of the slicing structure to slice by forward rotation and drives the cutter of the slicing structure to reset by reverse rotation and drives a prying rod of the film feeding structure to retract at the same time; a driving motor which drives the driving rod to rotate is arranged on the mounting seat.

[0006] Furthermore, the film feeding structure includes a film feeding driving arm, a film shifting rod, and a film feeding transmission rod disposed between the film feeding driving arm and the film shifting rod.

[0007] Furthermore, the slicing structure includes a slicing drive arm, a cutter, a cutter drive shaft, and a cutter transmission assembly disposed between the cutter drive shaft and the slicing drive arm.

[0008] Furthermore, a first driving structure that matches the driving rod and the slicing driving arm is provided, and the first driving structure includes a first cam provided on the driving rod and a first slot provided on the slicing driving arm.

[0009] Furthermore, a second driving structure that matches the driving rod and the film-feeding driving arm is provided, and the second driving structure includes a second cam provided on the driving rod and a second slot provided on the film-feeding driving arm.

[0010] Furthermore, a first return spring is provided between the mounting seat and the film feeding structure.

[0011] Further, a second return spring is provided between the mounting base and the slicing structure.

[0012] Further, a film feeding base plate is provided at the lower end of the film feeding structure, and a film feeding groove for film transportation is provided on the film feeding base plate.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] The present utility model provides a driving mechanism for gold embroidery, including a driving rod and a corresponding driving motor. The driving rod rotates forward to drive the cutter provided in the slicing structure to slice; the driving rod rotates reversely to drive the cutter provided in the slicing structure to reset, and at the same time, it also drives the paddle rod provided in the film feeding structure to retract. Using the same driving rod to drive the film feeding structure and the slicing structure can save costs and reduce space. The forward and reverse rotations drive respectively without mutual influence, and the efficiency is high.

[0015] When the driving rod rotates reversely to drive the paddle rod to retract, it can also drive the cutter to reset. By using the return spring and the reverse rotation of the driving rod to drive the cutter to reset at the same time, the reset speed of the cutter is greatly increased, making it easier to keep up with the speed of the machine needle going down, which can improve the running speed of the machine and the efficiency. It reduces problems such as incomplete slicing and affecting film feeding. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following further describes the present utility model in conjunction with specific embodiments.

[0022] In the present utility model, forward rotation and reverse rotation are relative concepts, that is, towards one direction and the opposite direction. In this embodiment, for the convenience of explaining the creative idea of the present utility model, as an example, "forward rotation" refers to clockwise rotation based on the attached drawings, and the "reverse rotation" refers to counterclockwise rotation based on the attached drawings.

[0023] Reference Figures 1-4 , a driving mechanism for gold flake embroidery, comprising a sheet feeding structure 1 and a slicing structure 2 provided on a mounting base 5, and further comprising a driving rod 3 that drives the cutter 202 of the slicing structure 2 to slice in the forward rotation and drives the cutter 202 of the slicing structure 2 to reset and simultaneously drives the paddle rod 102 of the sheet feeding structure 1 to retract in the reverse rotation. A driving motor 4 for driving the driving rod 3 to rotate is provided on the mounting base 5.

[0024] The sheet feeding structure 1 comprises a sheet feeding driving arm 101, a paddle rod 102, and a sheet feeding transmission rod 103 provided between the sheet feeding driving arm 101 and the paddle rod 102. The slicing structure 2 comprises a slicing driving arm 201, a cutter 202, a cutter driving shaft, and a cutter transmission assembly 203 provided between the cutter driving shaft and the slicing driving arm 201. The cutter transmission assembly can adopt the prior art.

[0025] A first driving structure 6 is provided between the driving rod 3 and the slicing driving arm 201. The first driving structure 6 comprises a first cam 601 provided on the driving rod 3 and a first slot 602 provided on the slicing driving arm 201. Of course, the first cam 601 can also be provided on the slicing driving arm 201, and the first slot 602 can be provided on the driving rod 3, as long as the cooperation between the driving rod 3 and the slicing driving arm 201 is ensured to realize the bidirectional driving of the driving rod 3 on the slicing driving arm 201.

[0026] A second driving structure 7 is provided between the driving rod 3 and the sheet feeding driving arm 101. The second driving structure 7 comprises a second cam 701 provided on the driving rod 3 and a second slot 702 provided on the sheet feeding driving arm 101. Of course, the second cam 701 can also be provided on the sheet feeding driving arm 101, and the second slot 702 can be provided on the driving rod 3, as long as the cooperation between the driving rod 3 and the sheet feeding driving arm 101 is ensured to realize the driving of the driving rod 3 on the sheet feeding driving arm 201.

[0027] A first return spring 8 is provided between the mounting base 5 and the sheet feeding structure 1. A second return spring 9 is provided between the mounting base 5 and the slicing structure 2.

[0028] When the driving rod 3 rotates forward, the first cam 601 cooperates with one end of the first slot 602 to drive the slicing driving arm 201 to swing, and drives the cutter driving shaft to rotate in the corresponding direction through the cutter transmission assembly 203, thereby driving the cutter 202 to slice.

[0029] When the driving rod 3 reverses, the first cam 601 cooperates with the other end of the first slot 602 to drive the slicing driving arm 201 to swing, and drives the cutter driving shaft to rotate in the corresponding direction through the cutter transmission assembly 203, so that the cutter 202 is reset. A second return spring 9 is provided between the mounting seat 5 and the slicing structure 2. The second return spring 9 is arranged between the mounting seat 5 and the slicing driving arm 201 to assist the slicing driving arm 201 to reset, that is, to assist the cutter 202 to reset. By the active drive of the driving rod 3 and the assistance of the second return spring 9 to reset the cutter, the reset speed of the cutter is faster, and it can keep up with the lower needle speed of the sewing needle faster, reducing the phenomena of missing slices and incomplete slicing.

[0030] While the driving rod 3 reverses, the second cam 701 cooperates with the second slot 702 to drive the sheet feeding driving arm 101 to swing, and drives the sheet pushing rod 102 to retract through the sheet feeding transmission rod 103. A first return spring 8 is provided between the mounting seat 5 and the sheet feeding structure 1. The first return spring 8 is arranged between the mounting seat 5 and the sheet feeding driving arm 101.
