Description

Technical Field

[0001] This technical solution relates to the field of template machine technology, and specifically refers to a cutting device for a template machine. Background Technology

[0002] Chinese patent CN114960054B discloses a cutting device for a sewing machine and a sewing machine. This cutting device has a separate drive motor and can independently perform cutting work. However, when this cutting device is working, because the cutter is flat and its two sides are the cutting surfaces, and the cutting edge is located at the intersection of the two cutting surfaces on the edge of the cutting surface, the cutter can only perform cutting work along the direction of the cutting surface. In the above-mentioned cutting device, the axis of the output shaft of the drive motor is perpendicular to the plane where the cutting surface is located. However, during the operation of the drive motor and the transmission to the cutting assembly through the crank-connecting rod assembly, the drive motor will inevitably swing perpendicular to the direction of the cutting surface. This swinging motion will cause the cutting edge to be subjected to a force perpendicular to the direction of the cutting surface during operation, which poses a risk of bending the cutter and can also cause damage to the fabric. Summary of the Invention

[0003] The purpose of this technical solution is to provide a cutting device for a template machine. By changing the setting direction of the drive motor, the axis of the output shaft is made parallel to the plane where the cutting blade is located, thus solving the problem that the cutting blade of the original equipment is always bent.

[0004] The purpose of this technical solution is achieved as follows:

[0005] A cutting device for a template machine includes: a frame; a drive motor mounted on the frame and having a horizontally arranged output shaft; a transmission mechanism disposed within the frame for receiving power input from the drive motor and transmitting the power to a cutting mechanism; and a cutting mechanism disposed at the output end of the transmission mechanism and including a vertically arranged cutting blade; wherein the axis of the output shaft of the drive motor is parallel to the plane containing the cutting blade.

[0006] Preferably, the transmission mechanism includes: a crank-connecting rod assembly connected to the output shaft; and a connecting assembly disposed on the inner wall of the frame for connecting the crank-connecting rod assembly and the cutting mechanism; wherein the crank-connecting rod assembly, in conjunction with the connecting assembly, is used to convert the rotation of the output shaft of the drive motor into the lifting and lowering of the cutting rod of the cutting mechanism.

[0007] Preferably, the crank-connecting rod assembly includes: a tool holder crank sleeved outside the output shaft; a crank pin disposed at the lower end of the tool holder crank; and a tool holder connecting rod, the upper end of which is sleeved outside the crank pin, and the lower end of which is connected to the connecting assembly; wherein the output shaft drives the tool holder crank to rotate, and the tool holder crank drives the tool holder connecting rod to swing.

[0008] Preferably, the connecting assembly includes: a guide slide, which is disposed on the inner wall of the frame and has a guide groove; a guide slider, which is movably disposed in the guide groove; and a connecting rod, the middle of which is connected to the lower end of the cutter bar connecting rod and the front end of which is connected to the guide slider; wherein the cutter bar of the cutter mechanism is disposed at the rear end of the connecting rod.

[0009] Preferably, the cutting mechanism includes: a cutting bar; a cutting holder disposed at the lower end of the cutting bar; and a cutting blade disposed on the cutting holder.

[0010] Preferably, the inner wall of the frame is provided with a mounting groove, and part of the transmission mechanism is disposed in the mounting groove.

[0011] Preferably, the frame is provided with a guide block, and the cutter holder end is provided with a guide part, which has a guide groove; the guide part moves on the guide block through the guide groove.

[0012] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0013] 1. The output shaft of the drive motor designed in this technical solution is parallel to the plane where the cutter blade is located. In this way, when the drive motor swings in any direction, it will not exert a force perpendicular to the direction of the cutter blade, thus ensuring that the cutter blade will not be bent.

[0014] 2. The crank-connecting rod assembly and connecting assembly designed in this technical solution work together to convert the rotation of the output shaft into the lifting and lowering of the cutting blade. Attached Figure Description

[0020] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 and Figure 2 As shown, the cutting device is installed inside the frame 1 of the template machine. The cutting device includes a drive motor 2, a transmission mechanism 3, and a cutting mechanism 4. The drive motor 2 is located at the rear of the frame 1 and has a horizontally arranged output shaft 21. The transmission mechanism 3 is located inside the frame 1 and is used to receive the power input from the drive motor 2 and transmit the power to the cutting mechanism 4. The cutting mechanism 4 is located at the output end of the transmission mechanism 3 and partially extends out of the frame 1. The cutting mechanism 4 includes a vertically arranged cutting blade 41. The axis of the output shaft 21 of the drive motor 2 is parallel to the plane where the cutting blade 41 is located. When the drive motor 2 is working, it will swing in the front-back and left-right directions. No matter which direction the swing is in, it will not affect the operation of the cutting blade 41 in this application, thus avoiding the bending of the cutting blade 41 and improving the processing quality of the fabric.

[0022] like Figure 2-4 As shown, the transmission mechanism 3 includes a crank-connecting rod assembly 31 and a connecting assembly 32. The crank-connecting rod assembly 31 is connected to the output shaft 21, and the connecting assembly 32 is disposed on the inner wall of the frame 1 for connecting the crank-connecting rod assembly 31 and the cutting mechanism 4. The crank-connecting rod assembly 31, in cooperation with the connecting assembly 32, is used to convert the rotation of the output shaft 21 of the drive motor 2 into the lifting and lowering of the cutting rod 42 of the cutting mechanism 4.

[0023] Furthermore, the crank-connecting rod assembly 31 includes a tool holder crank 311, a crank pin 312, and a tool holder connecting rod 313. The upper end of the tool holder crank 311 is sleeved outside the output shaft 21. The crank pin 312 is located at the lower end of the tool holder crank 311 and is connected to the tool holder connecting rod 313 through a bushing. The upper end of the tool holder connecting rod 313 is sleeved outside the crank pin 312, and the lower end is connected to the connecting assembly 32. The output shaft 21 drives the tool holder crank 311 to rotate, and the tool holder crank 311 drives the tool holder connecting rod 313 to swing.

[0024] like Figure 2-4As shown, the connecting assembly 32 includes a guide slide 321, a guide slider 323, and a connecting rod 324. The guide slide 321 is disposed on the inner wall of the frame 1 and has a vertical guide groove 322. The guide slider 323 is movably disposed in the guide groove 322. The middle part of the connecting rod 324 is connected to the lower end of the cutter bar connecting rod 313, the front end of the connecting rod 324 is connected to the guide slider 323, and the rear end of the connecting rod 324 is connected to the cutter bar 42 of the cutter mechanism 4. When the cutter bar connecting rod 313 swings, its lower end, through the limiting effect of the guide slider 323, will drive the guide slider 323 to rise and fall in the guide groove 322, thereby realizing the rising and falling of the cutter bar 42.

[0025] Furthermore, an installation groove 11 is provided on the inner wall of the frame 1. The guide slide 321 and the tool bar connecting rod 313 are arranged in the installation groove 11. The groove wall of the installation groove 11 can limit the tool bar connecting rod 313 to prevent its upper end from swinging excessively.

[0026] like Figure 2-4 As shown, the cutting mechanism 4 includes a cutting rod 42, a cutting holder 43, and a cutting blade 41. The upper end of the cutting rod 42 is connected to the connecting rod 324. The cutting holder 43 is set at the lower end of the cutting rod 42 by screws. The cutting blade 41 is set on the cutting holder 43 by screws.

[0027] like Figure 2-4 As shown, a guide block 12 is provided on the frame 1, and a guide part 431 is provided on the end side of the cutter holder 43. The guide part 431 has a guide groove 432. When the cutter holder 43 is installed, the guide block 12 can cooperate with the guide groove 432. The guide part 431 moves on the guide block 12 through the guide groove 432, thereby guiding the cutter blade 41.
