In the field of clothing, after the cutting process is completed, the obtained fabric pieces can be used for subsequent sewing, buttonhole sewing and other work.

[0003] In the existing cutting process, cutting equipment (or cutting machine, cutting bed) is usually used to perform cutting. The existing cutting equipment usually includes a frame for carrying, a support table for supporting fabrics, a controller, a position adjustment mechanism, and an electric cutting power head (or simply a cutting head), etc. The position adjustment mechanism is usually arranged on the frame, and the electric cutting power head is usually arranged on the position adjustment mechanism and corresponds to the support table below. The electric cutting power head is equipped with a blade (or punching knife, vibrating knife, etc.), and the controller is electrically connected to the position adjustment mechanism and the electric cutting power head, etc., respectively. The position adjustment mechanism is used to adjust the position of the electric cutting power head, and the electric cutting power head cuts the fabric through the blade under the control of the controller.

[0004] The existing electric cutting power head is also equipped with a cutting power, which is connected to the blade transmission and is used to drive the blade to reciprocate in the vertical direction so as to cut the tensioned fabric in the vertical direction. Since the fabric to be cut is usually tensioned on the support table, it is found in actual application that for fabrics that are not tensioned, the existing electric cutting power head is not only difficult to achieve accurate cutting, but also very likely to have problems such as uneven cutting and deviation of the cutting line, which affect the cutting effect, and it is also easy to have the problem of cutting failure; especially at the edge of the fabric, there is usually a problem of insufficient local tension, and the fabrics at these positions are usually loose, and the above problems are more obvious. Moreover, at the edge of the fabric, when using the existing electric cutting power head for cutting, it is also easy to have interference and cutting to the edge, which needs to be solved urgently.

Obviously, the described embodiment is only a part of the embodiment of the utility model, rather than all the embodiments. The components of the embodiment of the utility model generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiment of the utility model. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the utility model.

[0048] Example 1

[0049] The present embodiment provides an electric cutting power head assembly, including a first mounting frame 11, a cutting module and a static knife 3 arranged on the first mounting frame 11, wherein the first mounting frame 11 mainly plays the role of bearing and facilitating installation.

[0050] During implementation, the cutting module includes a cutting power 4 and a moving knife 2. The cutting power 4 is connected to the moving knife 2 in a transmission manner and is used to drive the moving knife 2 to rise and fall vertically, so as to achieve the effect of vibrating the moving knife 2 up and down, so that the moving knife 2 can perform cutting motion in the vertical direction. At the same time, the lower end of the moving knife 2 is configured to be inclined in the vertical direction, such as Figure 1 As shown, the lower end of the movable knife 2 is configured with a cutting edge 23, so that the cutting edge 23 is inclined in the vertical direction, as shown in FIG. Figure 1 As shown. Since the movable knife 2 can reciprocate in the vertical direction under the drive of the cutting power 4 during use, and the lower end of the movable knife 2 is constructed with a cutting blade 23, the movable knife 2 can be used to cut the cloth. In implementation, the cutting module can adopt the cutting module commonly used in the prior art that can drive the movable knife 2 (or called a punching knife or a vibrating knife 2) to perform cutting movement. In implementation, the cutting power 4 can preferably adopt a motor, such as a servo motor or a stepping motor. The cutting power 4 is connected to the movable knife 2 through a cutting transmission mechanism, and the cutting transmission mechanism is used to convert the rotational motion of the motor into a linear reciprocating motion that drives the movable knife 2 to perform cutting action. In implementation, the cutting transmission mechanism can be implemented using existing technology. As an example, the cutting transmission mechanism can adopt a crank 41 slider mechanism, such as Figures 3 - 8 As shown, the crank 41 slider mechanism includes a crank 41, a connecting rod 42, a sliding component 43 and a guide structure 5 adapted to the sliding component 43. The crank 41 is connected to the output shaft of the motor, and the motor is used to drive the crank 41 to rotate. One end of the connecting rod 42 is hinged to the crank 41, and the hinge position is offset from the rotation center of the crank 41. Figure 7 and Figure 8As shown, the other end of the connecting rod 42 is hinged to the sliding member 43. The sliding member 43 is movably constrained by the guiding structure 5. The guiding structure 5 is used to guide the linear movement of the sliding member 43. The guiding structure 5 is directly or indirectly connected to the first mounting bracket 11. The moving blade 2 is directly or indirectly connected to the sliding member 43. As Figure 8 shown. During use, the cutting power 4 drives the crank 41 to rotate. The crank 41 drives the sliding member 43 to make a linear reciprocating motion relative to the guiding structure 5 through the connecting rod 42, so that the moving blade 2 can perform a cutting motion.

[0051] To change the orientation of the cutting edge 23, in one embodiment, it further includes a bracket and a rotating power 7. The first mounting bracket 11 can be connected to the bracket through a bearing 9, so that the first mounting bracket 11 can rotate relative to the bracket, so that the cutting module can rotate relative to the bracket; the rotating power 7 can be arranged on the bracket and is in transmission connection with the first mounting bracket 11, so as to drive the entire cutting module to rotate (the rotation center is along the vertical direction) by using the rotating power 7, so as to achieve the purpose of adjusting the orientation of the moving blade 2.

[0052] In another embodiment, the cutting module can also adopt a cutting module commonly used in the prior art that can drive the moving blade 2 (or called a punching knife or a vibrating knife 2) to perform an up-and-down cutting motion and can also drive the moving blade 2 to perform a rotary cutting motion. At this time, the cutting module further includes a rotating power 7. The rotating power 7 is in transmission connection with the moving blade 2, so that the moving blade 2 can be driven to rotate by the rotating power 7, which can not only adjust the orientation of the moving blade 2, but also achieve the purpose of rotary cutting by using the rotating cutting edge 23. As an example, as Figures 3 - 8 shown, in this embodiment, the cutting module further includes a rotating transmission mechanism 71, a transmission rod 44 and a mounting head 45. The guiding structure 5 is configured as a hollow structure, and the guiding structure 5 is provided with a guiding hole 51 adapted to the sliding member 43; as Figure 8 shown, the guiding structure 5 can be connected to the first mounting bracket 11 through a bearing 9, so that the guiding structure 5 can rotate relative to the first mounting bracket 11. The rotating power 7 can be installed on the first mounting bracket 11. The rotating power 7 is in transmission connection with the guiding structure 5 through the rotating transmission mechanism 71, so as to drive the guiding structure 5 to rotate by using the rotating power 7; as Figure 8 shown, the sliding member 43 is slidably arranged in the guiding hole 51, and the guiding structure 5 can rotate relative to the sliding member 43. Therefore, during implementation, the guiding hole 51 is preferably configured as a circular hole, the sliding member 43 is also configured as a cylindrical structure, and the outer diameter of the sliding member 43 is smaller than the inner diameter of the guiding hole 51; as Figure 8As shown, the upper end of the transmission rod 44 is connected to the sliding member 43 through a bearing 9, the mounting head 45 is fixedly installed at the lower end of the transmission rod 44, a guiding notch 52 is formed on the side surface at the lower end of the guiding structure 5, the mounting head 45 is formed with a limiting protrusion 46 adapted to the guiding notch 52, the limiting protrusion 46 is inserted into the guiding notch 52, and the limiting protrusion 46 and the guiding notch 52 form a moving pair in the vertical direction, as Figure 5 and Figure 6 shown, the moving blade 2 is installed on the mounting head 45; in actual use, the cutting power 4 can drive the sliding member 43 to vertically lift relative to the guiding structure 5, the sliding member 43 drives the transmission rod 44 to vertically lift, the transmission rod 44 drives the mounting head 45 to vertically lift, and the mounting head 45 drives the moving blade 2 to vertically lift relative to the guiding structure 5, so as to achieve the purpose of driving the moving blade 2 to perform a cutting motion in the vertical direction. At the same time, in actual use, the rotating power 7 can drive the guiding structure 5 to rotate relative to the first mounting frame 11, and the guiding structure 5 drives the mounting head 45 to rotate through the cooperation of the guiding notch 52 and the limiting protrusion 46, and the mounting head 45 drives the moving blade 2 to rotate relative to the first mounting frame 11, so as to achieve the purpose of driving the moving blade 2 to rotate.

[0053] In implementation, the rotary transmission mechanism 71 can adopt one or a combination of a belt transmission mechanism, a gear transmission mechanism, a chain transmission mechanism, etc. For example, if the rotary power 7 is a motor, the rotary transmission mechanism 71 can adopt a synchronous belt transmission mechanism, and the synchronous belt transmission mechanism includes a driving pulley 711, a driven pulley 712 and a synchronous belt 713. The driving pulley 711 can be installed on the output shaft of the motor, and the driven pulley 712 can be arranged on the guiding structure 5, as Figure 3 、 Figure 4 and Figure 8 shown, the synchronous belt 713 can be tensioned between the driving pulley 711 and the driven pulley 712.

[0054] As Figure 1 and Figure 10 shown, in this embodiment, the moving blade 2 is further formed with a first cutting edge 24, and the first cutting edge 24 can be horizontally arranged or inclined relative to the horizontal direction, as Figure 1 shown, as long as the first cutting edge 24 faces upward. In a preferred implementation manner, the first cutting edge 24 is formed on the upper side of the moving blade 2 away from the cutting edge 23, as Figure 1 shown, which not only helps to simplify the structure of the entire moving blade 2, but also can effectively ensure the strength of the moving blade 2 and improve the stability and reliability of the moving blade 2. As an example, as Figure 1As shown, the moving knife 2 includes a connecting portion 21 and a knife head portion 22 connected to the lower end of the connecting portion 21. The connecting portion 21 is installed on the mounting head 45. A cutting edge 23 is formed at the lower end of the knife head portion 22, and a first trimming edge 24 is formed at the upper end of the knife head portion 22. The first trimming edge 24 corresponds to the cutting edge 23 below, as Figure 1 shown. In implementation, the connecting portion 21 may preferably adopt a strip structure, and the knife head portion 22 may preferably be configured as a triangular structure or a quadrilateral structure, etc.

[0055] In implementation, the stationary knife 3 may be installed on the cutting module or the first mounting bracket 11. By way of example, in this embodiment, the stationary knife 3 is installed on the guiding structure 5, as Figure 5 , Figure 7 and Figure 8 shown, so that the guiding structure 5, the stationary knife 3 and the moving knife 2 can rotate synchronously under the drive of the rotational power 7 to ensure that the orientations of the stationary knife 3 and the moving knife 2 are always consistent. As Figure 2 Figure 9 As shown, the stationary knife 3 is formed with a second trimming edge 31 adapted to the first trimming edge 24. The second trimming edge 31 faces the first trimming edge 24, and a trimming opening 33 (similar to scissors) is formed between the first trimming edge 24 and the second trimming edge 31. In use, when the cutting edge 23 makes a downward cutting movement driven by the moving knife 2, the first trimming edge 24 moves up and down relative to the second trimming edge 31 driven by the moving knife 2, so that a trimming movement can be realized through the cooperation of the first trimming edge 24 and the second trimming edge 31 to achieve the purpose of trimming the fabric.

[0056] In implementation, the position of the second trimming edge 31 is higher than that of the cutting edge 23, as Figure 8 shown; when the moving knife 2 moves to the lowest point, at least part of the second trimming edge 31 should be higher than the first trimming edge 24. In implementation, the second trimming edge 31 may be arranged horizontally or may be arranged obliquely with respect to the horizontal direction, as Figure 2 , Figures 9 - 12 shown, so that the second trimming edge 31 faces downward to cooperate with the first trimming edge 24.

[0057] It can be understood that in this embodiment, facing upward can be abbreviated as upward, including two cases of facing directly upward and facing obliquely upward. Similarly, in this embodiment, facing downward can be abbreviated as downward, including two cases of facing directly downward and facing obliquely downward, which will not be elaborated further hereinafter.

[0058] In implementation, the moving knife 2 may preferably adopt a plate-like structure as a whole. Correspondingly, the stationary knife 3 may also preferably adopt a plate-like structure as a whole. For example, the stationary knife 3 may preferably adopt an L-shaped plate-like structure, as Figure 2When assembled, the moving knife 2 and the stationary knife 3 are parallel to each other so that the first cutting edge 24 and the second cutting edge 31 can better cooperate with each other. When implemented, the moving knife 2 and the stationary knife 3 can be installed in a close fit, such as Figure 11 As shown, it is more conducive to the first cutting blade 24 and the second cutting blade 31 to achieve better cutting coordination, so as to better cut the fabric. At the same time, during implementation, the cutting blade 23 preferably adopts a double-sided edge, that is, the two sides of the lower end of the movable knife 2 are respectively opened with edges, and the edges on both sides together form the cutting blade 23. As shown in the figure, not only the cutting blade 23 is sharper, but also more conducive to high-speed up and down cutting movement; and when the movable knife 2 is performing rotary cutting, whether it is forward or reverse, the cutting blade 23 can be used to achieve a better rotary cutting effect, and the cutting edge is smoother. In addition, during implementation, there can also be a certain distance between the movable knife 2 and the static knife 3, so that the movable knife 2 and the static knife 3 do not contact each other, thereby avoiding the friction between the high-speed movable knife 2 and the static knife 3 to generate heat and cause damage to the fabric.

[0059] During implementation, both the first cutting blade 24 and the second cutting blade 31 can preferably adopt single-sided cutting edges. As shown in the figure, the first cutting blade 24 is cut on the side of the movable blade 2 away from the stationary blade 3. At the same time, the second cutting blade 31 is cut on the side of the stationary blade 3 away from the movable blade 2. As shown in the figure, not only can the first cutting blade 24 and the second cutting blade 31 form a sharper cutting fit, but also the cutting area is narrower, thereby meeting the cutting needs of a narrower cutting area.

[0060] In order to more conveniently fix the static knife 3 during assembly, during implementation, the static knife 3 is configured with a mounting portion for installation, and the mounting portion may include one or more mounting holes 32, as shown in the figure, so that the static knife 3 is fixedly mounted on the cutting module by a fastener 91 adapted to the mounting hole 32. For example, in an implementation provided in this embodiment, a clamping member 6 is also included, and the clamping member 6 can be detachably clamped to the lower end of the cutting module by a fastener 91. For example, the clamping member 6 can be clamped to the guide structure 5 by a fastener 91. The upper end of the static knife 3 is configured with two mounting holes 32, as shown in the figure. Accordingly, the clamping member 6 is configured with a first through hole 61 adapted to the two mounting holes 32. As shown in the figure, during assembly, the static knife 3 can be detachably mounted on the clamping member 6 by a fastener 91 adapted to the mounting hole 32 and the first through hole 61. During implementation, the clamping member 6 can preferably adopt a cylindrical structure, as shown in the figure. In this embodiment, the clamping member 6 is a clamping hoop, and the clamping member 6 is also configured with two second through holes 62 adapted to fasteners 91 such as bolts or screws, so that the clamping member 6 can hold the guide structure 5 tightly through the fasteners 91 adapted to the second through holes 62, as shown in the figure. It can be understood that in implementation, the guide structure 5 can be an integrally formed component, or can be composed of multiple components.

[0061] In a more complete embodiment,Figure 3 and Figure 4 As shown, the second mounting frame 12 and the lifting module are also included. The lifting module includes a lifting power 8. The first mounting frame 11 can be lifted and constrained to the second mounting frame 12, so that the first mounting frame 11 has the freedom of vertical lifting relative to the second mounting frame 12. The lifting power 8 is connected to the first mounting frame 11 in a transmission connection, and is used to drive the first mounting frame 11 to lift and lower vertically, so as to synchronously adjust the height of the moving knife 2 and the static knife 3. In order to enable the first mounting frame 11 to be lifted and lowered vertically with high precision, during implementation, the lifting module also includes a guide assembly, and the guide assembly includes a guide portion 81 and a matching portion 82 that are adapted to each other. The matching portion 82 can be moved movably on the guide portion 81, and the guide portion 81 is used to guide the matching portion 82. During implementation, the first mounting frame 11 is constrained to the second mounting frame 12 by the guide assembly, and the guide portion 81 can be arranged in the vertical direction to ensure that the matching portion 82 moves strictly in the vertical direction. As an example, the guide portion 81 can be set on the second mounting frame 12, and correspondingly, the matching portion 82 can be fixed to the first mounting frame 11. In implementation, the guide portion 81 may be a guide rail, and the matching portion 82 may be a slider adapted to the guide rail. Figure 3 or Figure 4 The guide portion 81 may also be a guide rod, and the matching portion 82 may be a guide ring adapted to the guide rod. In addition, the guide portion 81 may also be a guide groove, and the matching portion 82 may be a sliding block adapted to the guide groove.

[0062] In implementation, the lifting power 8 has a variety of implementation methods. For example, the lifting power 8 can use a cylinder or an electric push rod to directly drive the first mounting frame 11 to lift vertically. For another example, the lifting power 8 can also use a motor, such as a servo motor or a stepper motor. In this case, the lifting module also includes a linear transmission mechanism. The motor is connected to the first mounting frame 11 through a linear transmission mechanism to drive the first mounting frame 11 to lift vertically so as to synchronously adjust the height of the moving knife 2 and the stationary knife 3. In implementation, the linear transmission mechanism can use an existing linear transmission module. For example, the linear transmission mechanism can use a screw-nut transmission module, a gear-rack transmission module, etc. As an example, if Figure 7 and Figure 8 As shown, in this embodiment, the linear transmission mechanism adopts a screw-nut transmission module, which includes a screw 84 and a nut 85 adapted to the screw 84. The screw 84 is connected to the bearing seat 86 through the bearing 9, and the bearing seat 86 is fixed to the second mounting frame 12, so that the screw 84 is arranged in the vertical direction, as shown in FIG. Figure 3 and Figure 4As shown, accordingly, the nut 85 is fixed to the first mounting bracket 11 and threadedly connected to the lead screw 84. The motor can be drivingly connected to the linear drive mechanism through a drive mechanism 87 such as a coupling, a belt drive mechanism, a gear drive mechanism, a chain drive mechanism, etc. For example, in this embodiment, the drive mechanism 87 is a synchronous belt drive mechanism. The motor is fixed to the second mounting bracket 12. The synchronous belt drive mechanism includes a driving pulley 711, a driven pulley 712, and a synchronous belt 713. The driving pulley 711 is mounted on the output shaft of the motor, and the driven pulley 712 is mounted on the lead screw. As Figures 3 - 5 shown, the synchronous belt 713 is tensioned between the driving pulley 711 and the driven pulley 712, which can not only drive the first mounting bracket 11 to move up and down with high precision to achieve the purpose of precisely adjusting the heights of the moving cutter 2 and the stationary cutter 3, but also can arrange the motor flexibly and serve the purpose of overload protection.

[0063] During implementation, the second mounting bracket 12 in this power head assembly can be mounted on the cross beam of the cutting device. Multiple mounting holes 32 can be reserved in advance on the second mounting bracket 12 to facilitate the detachable mounting of the second mounting bracket 12.

[0064] During actual use, when it is necessary to cut the fabric with the moving cutter 2, only need to lower the cutting edge 23 to the position adapted to the fabric through the lifting power 8. When it is necessary to cut the edge of the fabric or cut the non-tensioned fabric, the first cutting edge 24 can be lowered below the fabric through the lifting power 8. Accordingly, the stationary cutter 3 is lowered synchronously, so that the second cutting edge 31 just synchronously descends above the fabric. Thus, the fabric can be cut by the cooperation of the first cutting edge 24 and the second cutting edge 31, which can not only achieve better results, but also solve the problems that the edge of the fabric is not easy to be cut and the cutting effect is poor. Since this design has two working modes of cutting and trimming, the user can switch according to actual needs, which better meets the market demand.

[0065] Embodiment 2

[0066] To improve the movement accuracy of the moving cutter 2 and at the same time simplify the structure and reduce the manufacturing difficulty, the main difference between this embodiment and the above embodiment is that in the electric cutting power head assembly provided in this embodiment, the guiding structure 5 includes a guiding cylinder 53 and a guiding shaft 54. Among them, as Figure 15 shown, a guiding hole 51 is formed in the guiding cylinder 53, and the guiding hole 51 penetrates through the lower end of the guiding cylinder 53. The guiding shaft 54 is formed with a slideway 55 adapted to the transmission rod 44. As Figure 15 shown, a guiding notch 52 can be formed on the side surface of the guiding shaft 54 and communicated with the slideway 55. During assembly, the guiding shaft 54 is mounted at the lower end of the guiding cylinder 53 and coaxial with the guiding cylinder 53. As Figure 15As shown, the slideway 55 is connected to the guide hole 51. In implementation, the guide shaft 54 can be detachably mounted on the guide cylinder 53. For example, the lower end of the guide hole 51 is configured with an internal thread, and the guide shaft 54 is configured with an external thread adapted to the internal thread, so that the guide shaft 54 can be threadedly connected to the lower end of the guide cylinder 53, as shown in FIG. Figure 15 In another embodiment, the upper end of the guide cylinder 53 is also configured with an inner cavity 56, as shown in FIG. Figure 15 As shown, the inner cavity 56 is connected to the guide hole 51, and the inner diameter of the inner cavity 56 is larger than the inner diameter of the guide hole 51, so as to provide a larger movement space for the connecting rod 42 to prevent interference with the movement of the connecting rod 42.

[0067] like Figure 15 As shown, the mounting head 45 is constructed with an adapting hole 451 adapted to the guide shaft 54 and an assembly hole 452 adapted to the movable knife 2, and the limiting protrusion 46 is constructed with a threaded hole 461 connected to the assembly hole 452, and the assembly hole 452 is connected to the adapting hole 451. During assembly, the mounting head 45 is sleeved on the guide shaft 54 through the adapting hole 451, and the connecting portion 21 of the movable knife 2 is inserted into the assembly hole 452, and a fastener 91 such as a bolt or a screw is installed in the threaded hole 461, so that the fastener 91 can be used to simultaneously lock the mounting head 45 to the guide shaft 54 and the movable knife 2 to the mounting head 45, thereby making the installation and replacement of the movable knife 2 very convenient.

[0070] In the case where the lifting power 8 is not configured, in order to facilitate switching the working mode of the electric cutting power head assembly and adapt to different thicknesses of fabrics, the electric cutting power head assembly can be installed on the position adjustment mechanism during implementation, so that the position and height of the electric cutting power head assembly can be adjusted by the position adjustment mechanism, so that the two working modes (i.e., cutting mode and cutting mode) can be conveniently switched by changing the height of the electric cutting power head assembly, which is very convenient and efficient. The position adjustment mechanism can be implemented using existing technology and will not be described in detail here.
