Description

Technical Field

[0001] The present application relates to the technical field of garment processing equipment, and in particular to an independent cutting device based on a flat car and a working method. Background Art

[0002] With the development of technology in the field of garment manufacturing, there has been an emergence of automatic machine technology in the form of manipulators, which can automate processes such as upper collars or cuffs, improving production efficiency. The characteristic of this technology is that it integrates the action of the cutter and the sewing machine needle in one body, aiming to achieve the continuity of cutting and sewing.

[0003] In the related art, this integrated cutter flat sewing machine is usually used to process the stopper in the process. However, in actual application, due to the simultaneous action of the cutter and the sewing machine needle, the cutter and the fabric often interfere when processing the corner or arc position of the cut piece, thereby affecting the forming effect of the cut piece.

[0004] However, the above-mentioned integrated cutter flat car method has obvious limitations. It cannot effectively avoid the interference between the cutter and the fabric in the processing of complex-shaped pieces, which in turn affects the final quality of the product. Therefore, although automation has brought about efficiency improvements, this problem still plagues producers in the garment industry and results in the need to rely on manual cutting of the stop in actual production, thereby increasing the number of processes and reducing overall production efficiency.

[0005] Therefore, in order to solve the above technical problems, it is urgent to study a cutting device that can be independent of the sewing action of the sewing machine to solve the problems existing in automatic machine production. Summary of the invention

[0006] Based on this, it is necessary to provide an independent cutting knife device and working method based on a flat car to address the above problems, so that the cutter can be independent of the sewing action of the sewing machine. When cloth passes through, the cutter can cut off the incoming cloth by moving up and down without affecting the forming effect of the cut piece.

[0007] An independent cutting device based on a flat car comprises:

[0008] Mechanism fixing plate, used to assemble the entire cutter device on the flat car;

[0009] A driving motor is fixed on a driving motor fixing seat, and the driving motor fixing seat is fixed on the mechanism fixing plate;

[0010] A transmission mechanism, used for transmitting the driving force provided by the driving motor to the transmission eccentric shaft;

[0011] The transmission eccentric shaft has one end supported by the driving motor fixing seat and the other end connected to the connecting rod mechanism;

[0012] A connecting rod mechanism is connected to the cutter fixing mechanism and is used to drive the cutter fixing mechanism to move;

[0013] A cutter is fixed at the end of the cutter fixing mechanism and is directly opposite to the position where the cloth passes;

[0014] At least one limiting mechanism is used to constrain the movement direction of the cutter fixing mechanism.

[0015] In one embodiment, the limiting mechanism includes a first radial limiting mechanism and a second radial limiting mechanism; one end of the first radial limiting mechanism is connected to the cutter fixing mechanism to limit the linear movement of the cutter fixing mechanism in the vertical direction; the cutter fixing mechanism and the second radial limiting mechanism are slidably matched to provide stability and guidance for the cutter fixing mechanism on the movement path.

[0016] In one of the embodiments, the second radial limiting mechanism is fixed on the bottom plate of the mechanism fixing plate, and the cutter fixing mechanism slides freely in the second radial limiting mechanism in the vertical direction; the first radial limiting mechanism and the second radial limiting mechanism work together to make the cutter fixing mechanism face the position where the cloth passes and move up and down in the vertical direction.

[0017] In one embodiment, the mechanism fixing plate includes a sewing machine fixing plate, a transition plate and a bottom plate, and the sewing machine fixing plate, the transition plate and the bottom plate are a separate structure or an integrated structure;

[0018] Furthermore, the sewing machine fixing plate, transition plate and bottom plate are split structures; the sewing machine fixing plate is fixed to the side or top surface of the sewing machine, one side of the bottom plate is connected to the sewing machine fixing plate through the transition plate, and the other side of the bottom plate is attached to the plane of the sewing machine.

[0019] In one of the embodiments, the transmission mechanism includes two synchronous wheels, one of which is fixed to the output end of the drive motor, and the other is fixedly connected to the transmission eccentric shaft. The two synchronous wheels in the transmission mechanism cooperate with each other for synchronous transmission, so that the driving force output by the drive motor is transmitted to the transmission eccentric shaft.

[0020] In one embodiment, the power transmission between the two synchronous wheels is achieved through a transmission medium, and the structure of the transmission medium is a belt transmission structure, a chain transmission structure or a gear transmission structure.

[0021] In one embodiment, the transmission eccentric shaft and the connecting rod mechanism are connected via a bearing.

[0022] A working method of an independent cutting device based on a flat car, using the cutting device to cut cloth, includes the following steps:

[0023] The driving motor rotates, driving the transmission mechanism connected thereto to rotate;

[0024] The transmission mechanism transmits the driving force to the transmission eccentric shaft, causing the transmission eccentric shaft to rotate;

[0025] Since the transmission eccentric shaft is an eccentric structure, when it rotates, the eccentric side will drive the connecting rod mechanism to perform an elliptical rotation motion;

[0026] The connecting rod mechanism drives the cutter fixing mechanism to perform elliptical rotational motion;

[0027] The cutter fixing mechanism is connected to the first radial limiting mechanism, and the cutter fixing mechanism slides in the second radial limiting mechanism, thereby limiting the cutter fixing mechanism to move up and down only along the vertical direction with the first radial limiting mechanism;

[0028] The cutter is fixed on the cutter fixing mechanism, and when cloth passes through, the cutter cuts the cloth by moving up and down.

[0029] In one of the embodiments, the mechanism fixing plate fixes the entire set of cutter devices to the side or top of the flat car, and the position of the mechanism fixing plate is adjusted according to different types of flat cars during fixing.

[0030] The above-mentioned independent cutting knife device and working method based on the flat car can realize the lifting and lowering of the knife to cut the cloth at any time or position during the sewing process of the cut piece through the independent cutting knife structure and the control of the sewing machine, which is more flexible; at the same time, it solves the problem that the flat car with its own cutter can only move together with the sewing machine needle during the cutting process, and cannot avoid interference with the arc or corner position of the cut piece when the cutter is lowered, causing the cut piece to arch and affect the forming effect of the cut piece. The present application enables the cutter to be independent of the sewing action of the sewing machine needle, and will not affect the forming effect of the cut piece.

[0048] Embodiment 1:

[0049] Please refer to FIG1 , which shows a schematic diagram of the overall structure of a cutter device in one embodiment of the present application.

[0050] In conjunction with FIG. 2 , FIG. 2 shows a top view of FIG. 1 .

[0051] An independent cutter device based on a flat car provided in an embodiment of the present application includes the following parts: a mechanism fixing plate 1, a drive motor 2, a drive motor fixing seat 3, a transmission mechanism 4, a transmission eccentric shaft 5, a connecting rod mechanism 6, a first radial limiting mechanism 7, a cutter fixing mechanism 8, a second radial limiting mechanism 9 and a cutter 10. The entire device is assembled on a sewing machine 11 through the mechanism fixing plate 1.

[0052] The structure of the mechanism fixing plate 1 is as follows: The mechanism fixing plate 1 is used to assemble the entire cutter device on the sewing machine 11, specifically, it includes a sewing machine fixing plate 101, a transition plate 102 and a bottom plate 103 (see Figure 3 and Figure 4 ). The sewing machine fixing plate 101 is fixed to the side of the sewing machine 11, the transition plate 102 is connected between the sewing machine fixing plate 101 and the bottom plate 103, and one side of the bottom plate 103 is attached to a plane of the sewing machine 11, thereby ensuring that the cutter device is firmly installed on the sewing machine. Specifically, the mechanism fixing plate 1 in this embodiment is a split structure, which is formed by the cooperation of the sewing machine fixing plate 101, the transition plate 102 and the bottom plate 103.

[0053] The installation structure of the drive motor 2 is as follows: the drive motor 2 is fixed on the drive motor fixing seat 3, and the drive motor fixing seat 3 is fixed on the bottom plate 103. In this way, the position of the drive motor 2 is relatively stable, and a stable driving force can be provided for the subsequent transmission mechanism.

[0054] The transmission structure is as follows: the transmission mechanism 4 is used to transmit the driving force provided by the driving motor 2 to the transmission eccentric shaft 5. Figure 5-6 The figure shows the transmission matching view in this embodiment, and the transmission mechanism 4 adopts the synchronous wheel transmission form. Specifically, the transmission mechanism 4 includes two synchronous wheels, one of which is fixed to the output end of the driving motor 2, and the other synchronous wheel is fixedly connected to the transmission eccentric shaft 5. The two synchronous wheels realize power transmission through a synchronous belt. When the driving motor 2 rotates, the driving force is transmitted to the transmission eccentric shaft 5 through the cooperation of the synchronous wheel and the synchronous belt, so that it rotates.

[0055] The connection structure between the transmission eccentric shaft 5 and the connecting rod mechanism 6 is as follows: one end of the transmission eccentric shaft 5 is supported by the driving motor fixing base 3, and the other end is connected to the connecting rod mechanism 6 through a bearing. In this way, the rotational motion of the transmission eccentric shaft 5 can be converted into the rotational motion of the connecting rod mechanism 6.

[0056] The installation structure of the cutter fixing mechanism 8 and the cutter 10 is as follows: the connecting rod mechanism 6 is connected to the cutter fixing mechanism 8, and is used to drive the cutter fixing mechanism 8 to move. The cutter 10 is fixed at the end of the cutter fixing mechanism 8, and the cutter 10 is directly opposite to the position where the cloth passes. When the cloth passes, the cutter 10 will perform a cutting action.

[0057] The limiting structure is as follows: in order to ensure that the cutter 10 can move along a specific direction (vertical direction in this example), two limiting mechanisms are provided: a first radial limiting mechanism 7 and a second radial limiting mechanism 9;

[0058] Specifically, the first radial limiting mechanism 7: one end of the mechanism is connected to the cutter fixing mechanism 8, and is used to limit the straight-line movement of the cutter fixing mechanism 8 in the vertical direction. In this embodiment, the first radial limiting mechanism 7 adopts a slider rail structure to achieve the movement limiting effect;

[0059] Specifically, the second radial limiting mechanism 9 is fixed on the bottom plate 103, and the cutter fixing mechanism 8 slides freely in the vertical direction in the second radial limiting mechanism 9. In this way, the second radial limiting mechanism 9 not only provides stability for the cutter fixing mechanism 8 on the movement path, but also plays a guiding role.

[0060] The first radial limiting mechanism 7 and the second radial limiting mechanism 9 of the present application cooperate with each other to ensure that the cutter fixing mechanism 8 is directly opposite to the position where the cloth passes and moves up and down in the vertical direction.

[0061] The working method in this embodiment is as follows: when the driving motor 2 rotates, the driving force is transmitted to the transmission eccentric shaft 5 through the transmission mechanism 4 to make it rotate. Since the transmission eccentric shaft 5 is an eccentric structure, when it rotates, the eccentric side will drive the connecting rod mechanism 6 to make an elliptical rotational motion. The movement of the connecting rod mechanism 6 then drives the cutter fixing mechanism 8 to make the same elliptical rotational motion. However, since the cutter fixing mechanism 8 is connected to the first radial limiting mechanism 7 and slides in the second radial limiting mechanism 9, these limiting mechanisms limit the cutter fixing mechanism 8 to only make linear movements up and down in the vertical direction. Therefore, when the cloth passes under the cutter 10, the cutter 10 cuts the cloth by moving up and down.

[0062] Embodiment 2:

[0063] See also Figure 8 , which is a schematic diagram of the assembly state of the cutting device and the sewing machine 11 in another embodiment of the present application.

[0064] The difference between this embodiment and the above-mentioned embodiment 1 is that the installation structure of the mechanism fixing plate 1 is different.

[0065] Specifically, in this embodiment, the mechanism fixing plate 1 fixes the entire set of cutting devices to the top of the sewing machine 11 (see Figure 8). This installation method can adjust the position of the mechanism fixing plate 1 according to different types of sewing machines 11, so that the cutter device can flexibly adapt to various types of sewing machines. In addition, installing the cutter device on the top of the sewing machine may be more conducive to the cutting operation, especially when processing high-position cut pieces.

[0066] Except for the installation position and method of the mechanism fixing plate, the implementation method of other parts of the structure in this embodiment is exactly the same as that in the above-mentioned embodiment 1.

[0067] Embodiment three:

[0068] The difference between this embodiment and the above-mentioned embodiment 1 is that the implementation method of the transmission mechanism 4 is different.

[0069] In the first embodiment, the transmission mechanism 4 adopts a transmission form of synchronous wheels and synchronous belts. However, the transmission mechanism 4 in this embodiment is not limited to synchronous wheel transmission. In this embodiment, the transmission mechanism 4 can adopt other forms of transmission, such as gear transmission or motor direct drive.

[0070] Gear transmission: The transmission mechanism 4 may include two meshing gears, one of which is fixed to the output end of the drive motor 2, and the other is fixedly connected to the transmission eccentric shaft 5. When the drive motor 2 rotates, the driving force is transmitted to the transmission eccentric shaft 5 through the meshing of the gears.

[0071] Direct motor drive: In some cases, a drive motor 2 may also be configured, and the output shaft of the drive motor 2 may be directly connected to the transmission eccentric shaft 5 via a coupling, thereby omitting the intermediate transmission mechanism.

[0072] Regardless of which transmission mode is adopted, the purpose of the transmission mechanism 4 is to transmit the driving force provided by the driving motor 2 to the transmission eccentric shaft 5 to drive the subsequent cutting action.

[0073] In this embodiment, except for the different implementations of the transmission mechanism 4, the implementations of other structures in this embodiment are exactly the same as those in the first embodiment, and their working principles and structural features are also consistent.

[0074] Embodiment 4:

[0075] The difference between this embodiment and the above-mentioned embodiment 1 is that the structure of the limiting mechanism is different.

[0076] Regarding the structure of the first radial limiting mechanism 7: In the first embodiment, the first radial limiting mechanism 7 adopts a slider rail structure. However, the first radial limiting mechanism 7 in this embodiment is not limited to the slider rail structure. In this embodiment, the first radial limiting mechanism 7 can adopt a guide shaft or a dovetail groove structure to achieve the same motion limiting effect.

[0077] Guide shaft: The first radial limiting mechanism 7 may include a guide shaft and a guide sleeve; the guide shaft is fixed on the cutter fixing mechanism 8, and the guide sleeve is fixed on the mechanism fixing plate 1; when the cutter fixing mechanism 8 moves, the guide shaft slides in the guide sleeve, thereby limiting its movement direction.

[0078] Dovetail groove: The first radial limiting mechanism 7 can also adopt a dovetail groove structure; the dovetail groove is fixed on the mechanism fixing plate 1, and a slider matching the dovetail groove is fixed on the cutter fixing mechanism 8; when the cutter fixing mechanism 8 moves, the slider slides in the dovetail groove, thereby limiting its movement direction.

[0079] In this embodiment, the structure of the first radial limiting mechanism 7 includes but is not limited to the matching form of the guide shaft and the guide sleeve and the matching form of the slider and the dovetail groove. However, no matter which form, the core function of the first radial limiting mechanism 7 is to limit the cutter fixing mechanism 8 to perform linear motion along a specific direction (vertical direction in this case).

[0080] Embodiment five:

[0081] The difference between this embodiment and the above-mentioned embodiment 1 is that the structure of the mechanism fixing plate 1 is different.

[0082] In the first embodiment, the mechanism fixing plate 1 includes a sewing machine fixing plate 101, a transition plate 102 and a bottom plate 103, which are separate structures. However, the mechanism fixing plate 1 of the present invention can also be an integrated structure.

[0083] In actual work, the mechanism fixing plate 1 can be in the form of a split structure or an integrated structure to adapt to different installation requirements and manufacturing convenience.

[0084] Exemplarily, the mechanism fixing plate 1 in this embodiment is an integrated structure, which is designed as an integral plate-like structure, on which a mounting surface for fixing the drive motor fixing seat 3 and other components is directly provided.

[0085] In this embodiment, except for the different implementations of the mechanism fixing plate 1, the implementations of other parts in this embodiment are exactly the same as those in the first embodiment. Therefore, their working principles and structural features are also consistent.

[0086] The present application uses an independent cutting knife device in conjunction with the sewing machine control, so that the cutting knife can be lifted and lowered to cut the cloth at any time or position during the sewing process, which is more flexible; at the same time, it solves the problem that a flat sewing machine with its own cutting knife can only move together with the sewing machine needle during the stop cutting process and cannot avoid interference with the cutting knife when the cutting knife is lowered at the arc or corner position of the cutting piece, causing the cutting piece to bulge and affecting the forming effect of the cutting piece; in the present application, when the cloth passes through, the cutting knife 10 cuts off the incoming cloth by moving up and down, which will not affect the forming effect of the cutting piece.

[0087] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0088] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
