The cutting device is used for cutting and cutting sheets in various industries, is controlled by system software, and then directly cuts corresponding products. Corresponding parameters are set on the operating platform, corresponding instructions are transmitted to the cutting device by the computer, the cutting machine performs rapid cutting according to the received design drawings, and the automatic program is high. The cutting equipment used at present is generally industrially used, has high manufacturing cost, large volume and limited application occasions, and cannot be used for cutting various sheet materials when in use. Since there is a higher demand for pressure regulation when cutting sheet materials, in the related art, a transmission mechanism such as a rack and pinion structure capable of performing linear motion is usually disposed in the cutting device to perform cutting, scribing, and other actions. For example, the gear is in transmission connection with the driving mechanism, the rack is connected with a structure provided with a workpiece, the driving gear rotates through the driving mechanism, and the gear is meshed with the rack, so that the rack moves along a linear direction, and the workpiece moves along the linear direction.

The inventor of the present application has noticed that, in order to achieve higher required pressure regulation, higher manufacturing and mounting accuracy of the rack-and-pinion structure is required, and meanwhile, the smaller the pitch between the teeth of the rack and the pitch between the teeth of the rack, the more precise the transmission of the rack-and-pinion structure is. However, in this process, wear and play between the teeth of the gear and the teeth of the rack are more likely to occur, which leads to situations in which continuous pressure regulation and failure of the transmission are not well achieved.

Based on this, this application embodiment avoids producing some of the above-mentioned problems through improving transmission mode. The following describes the pressure regulating device and the cutting device provided in the embodiments of the present application with reference to the related descriptions of some embodiments.

Fig. 1 shows a schematic perspective view of a pressure control device 10 according to an embodiment of the present disclosure; FIG. 2 illustrates a schematic perspective view of the pressure regulating device 10 with the housing 120 removed from a perspective view in an embodiment of the present application; FIG. 3 illustrates a schematic perspective view of the pressure regulating device 10 from another perspective with the housing 120 removed according to an embodiment of the present disclosure; fig. 4 is a schematic perspective view of the pressure control device 10 with the moving member 300 removed in one embodiment of the present application; for convenience of explanation, only portions related to the embodiments of the present application are shown.

Referring to fig. 1 to 4, an embodiment of the present application provides a pressure regulating device 10, where the pressure regulating device 10 includes a pressure regulating mechanism 200 and at least one moving member 300 for mounting a processing tool 20. The pressure regulating mechanism 200 includes a driving assembly 210 and a guiding element 220, and the moving element 300 is in transmission connection with the driving assembly 210 and is slidably connected to the guiding element 220 to reciprocate linearly along the first direction F1 under the driving of the driving assembly 210. The driving assembly 210 includes a transmission member 211 having a rotation center line L1 (refer to fig. 8 and fig. 9 illustrated later), and an output shaft 212 eccentrically disposed on the transmission member 211, the moving member 300 is provided with a limiting groove 310, and the output shaft 212 can extend into the limiting groove 310 and abut against an inner wall of the limiting groove 310, so as to convert a rotational motion of the transmission member 211 into a linear motion of the moving member 300. In some embodiments, referring to fig. 1, the pressure regulating device 10 further includes a device body 110 and a housing 120, the pressure regulating mechanism 200 is mounted on the device body 110, the housing 120 is detachably connected to the device body 110, and the moving member 300 and the pressure regulating mechanism 200 can be accommodated in a space formed between the housing 120 and the device body 110, so that a good appearance can be obtained and the pressure regulating mechanism 200 and the moving member 300 can be protected. Of course, in other embodiments, referring to fig. 5 shown later, an accommodating space of the pressure adjusting mechanism 200 may also be formed in the moving member 300, so as to form a structural form that the moving member 300 covers the pressure adjusting mechanism 200.

It should be noted that the phrase "at least one moving member 300 for mounting the processing tool 20" means that one or more moving members 300 can be provided for mounting the processing tool 20, and the same processing tool 20 can be mounted in each of the plurality of moving members 300, or different processing tools 20 can be mounted in each of the plurality of moving members 300. Taking fig. 2 and fig. 3 as an example, a situation that two moving members 300 are provided in the pressure regulating device 10 is illustrated, and the same processing tool 20 may be installed in the two moving members 300, or different processing tools 20 may be installed in the two moving members 300. "the output shaft 212 eccentrically provided to the transmission member 211" means that the center of rotation of the output shaft 212 is different from and has a certain distance from the center of rotation of the transmission member 211. It can be understood that, for the same rotation angle of the transmission member 211, the larger the distance generated by the eccentricity is, the larger the rotation stroke of the output shaft 212 is, and the larger the relative displacement between the output shaft 212 and the limiting groove 310 is, and under the action, the moving member 300 follows along the guide member 220. The distance may be adjusted according to the stroke of the moving member 300 and the driving precision required for practical use, which is not particularly limited by the embodiment of the present application.

In some embodiments, the output shaft 212 and the transmission member 211 may be of an integrally formed structure or a split structure. When the output shaft 212 and the transmission member 211 are designed to be a split structure, the output shaft 212 and the transmission member 211 can be fixedly connected or rotatably connected to each other, so that flexible regulation and control processes of different degrees can be realized. For example, when the output shaft 212 is rotatably connected to one side of the transmission member 211, different driving power sources may be provided between the output shaft 212 and the transmission member 211, so that a more precise flexible regulation process may be obtained by providing different rotation speeds.

Therefore, the limiting groove 310 is formed in the moving member 300, the output shaft 212 of the driving component 210 is eccentric to the transmission piece 211, and the eccentric output shaft 212 is coupled with the limiting groove 310, so that the moving member 300 can move on the guide piece 220 under the direct action of the output shaft 212 of the driving component 210 and the limiting groove 310, the abrasion of the driving component 210 is reduced, and the reliability of the whole device is improved.

Fig. 5 is a schematic perspective view illustrating the pressure control device 10 for opening the moving member 300 from a viewing angle according to an embodiment of the present disclosure; fig. 6 is a schematic perspective view illustrating the pressure control device 10 for opening the moving member 300 from another view in an embodiment of the present application; FIG. 7 is a schematic cross-sectional view of a transmission member 211 engaged with a moving member 300 according to an embodiment of the present application; for convenience of explanation, only portions related to the embodiments of the present application are shown.

In order to make the conversion process of the rotational motion of the transmission member 211 into the linear motion of the moving member 300 smoother when the output shaft 212 abuts against the inner wall of the limiting groove 310, in some embodiments, referring to fig. 5 to 7, the inner wall of the limiting groove 310 is configured as a curved surface which is in smooth transition and matches with the outline shape of the output shaft 212. Specifically to some embodiments, the inner wall of the limiting groove 310 further includes a plane connected to the two ends of the curved surface, so that when the output shaft 212 moves to the corresponding plane from the two ends of the curved surface in a smooth transition manner, the conversion process is buffered, and the moving member 300 is prevented from shaking.

FIG. 8 is a schematic diagram illustrating the structure of the transmission member 211 at a viewing angle according to an embodiment of the present application; FIG. 9 is a schematic diagram illustrating the structure of the transmission member 211 from another perspective in one embodiment of the present application; for convenience of explanation, only portions related to the embodiments of the present application are shown.

Referring to fig. 8 and 9 in combination with fig. 5 and 6 illustrated above, in some embodiments, the driving assembly 210 further includes a socket 213 that is sleeved on the output shaft 212. That is to say, the output shaft 212 generates relative motion with the aid of the socket 213 and the limiting groove 310, and the socket 213 directly contacts with the inner wall of the limiting groove 310, so that not only can the abrasion generated between the output shaft 212 and the inner wall of the limiting groove 310 be reduced, but also the socket 213 can be replaced conveniently, and the cost is reduced. In some embodiments, the friction coefficient of the socket 213 is smaller than the friction coefficient of the inner wall of the limiting groove 310. Thus, the relative movement between the output shaft 212 and the limiting groove 310 is facilitated to make the conversion process more stable and smooth, so that the processing tool 20 can have a more stable processing process.

With continued reference to fig. 5 and 6, in some embodiments, the pressure regulating mechanism 200 further includes an elastic member 230. One end of the elastic member 230 is connected to the transmission member 211, and the other end is connected to the moving member 300, for providing an elastic force acting on the moving member 300 according to the relative movement between the transmission member 211 and the moving member 300. Alternatively, the elastic member 230 may be provided with a structure such as a tension spring, so that, due to the elastic member 230, the processing process of the processing tool 20 mounted on the moving member 300 can be controlled by the elastic force during the moving process of the moving member 300. In order to provide the elastic force provided by the elastic member 230 with a larger range of elasticity in use, in some embodiments, the other end of the elastic member 230 may be connected to the top end of the moving member 300, and the transmission member 211 may be disposed relatively at the lower portion of the moving member 300. Of course, other arrangements may be adopted, and this is not particularly limited in the embodiments of the present application.

In some embodiments, the output shaft 212 is eccentrically disposed on one side of the transmission member 211, and the pressure regulating mechanism 200 further includes a connecting member 214 disposed on the periphery of the transmission member 211 and adjacent to the output shaft 212, wherein the transmission member 211 is connected to one end of the elastic member 230 by the connecting member 214. Alternatively, the connection 214 may be provided in the form of a link. The length of the connecting member 214 and the angle of offset of the connecting member 214 with respect to the center line of rotation L1 of the transmission member 211 can be set according to the use requirement. To better achieve pressure regulation, in some embodiments, referring to fig. 8 and 9, the extending direction of the perpendicular line between the central axis of the output shaft 212 and the rotation center line L1 of the transmission member 211 is the second direction F2. The connecting member 214 has a first end connected to the periphery of the driving member 211, and a second end opposite to the first end. One end of the elastic member 230 is connected to the second end. The direction in which the first end points to the second end is a third direction F3, and the third direction F3 and the second direction F2 are parallel to each other. For example, fig. 8 and 9 illustrate a case where the rotation center of the transmission member 211, the axial center of the output shaft 212, and the third direction F3 are substantially in the same plane. The elastic force of the elastic member 230 on the connecting member 214 is on the same side of the transmission member 211 as the force of the output shaft 212 on the moving member 300, so that the motion conversion process can be flexibly adjusted more deeply.

With continued reference to fig. 4-6, in some embodiments, the transmission member 211 is a gear plate. The drive assembly 210 further includes a drive member (not shown), a first gear 215 drivingly connected to the drive member, and a gear set 216 engaged between the first gear 215 and the drive member 211. In this manner, the gear ratio of the transmission member 211 may be adjusted through a gear transmission process. Taking fig. 4 to 6 as an example, a situation where two second gears are disposed in the gear set 216 is illustrated, the two second gears are disposed on the same transmission shaft, one of the two second gears is meshed with the first gear 215, and the other is meshed with the transmission member 211, so that the moving process of the moving member 300 can be adjusted more accurately. The number of the second gears can be selected according to actual use conditions, and the embodiment of the present application is not particularly limited in this respect.

In order to further combine the moving process of the linear motion of the moving member 300 to regulate the pressure of the whole device, please refer to fig. 8 and 9, in some embodiments, the transmission member 211 is an incomplete gear. Alternatively, the central axis of the output shaft 212 and the rotation center line L1 of the transmission member 211 are parallel to each other, and a plane passing through the central axis of the output shaft 212 and the rotation center line L1 of the transmission member 211 is defined as a reference plane P, and the gear teeth of the transmission member 211 are disposed on both sides of the reference plane P and are symmetrical with respect to the reference plane P. That is, since a portion of the edge of the transmission member 211 is provided with gear teeth and a portion of the edge is not provided with gear teeth, when the output shaft 212 and the limiting groove 310 generate relative movement, the process may at least include the following cases: (1) the second gear 216 is engaged with the transmission member 211, the transmission member 211 drives the output shaft 212 to move, and the clockwise rotation or the counterclockwise rotation of the transmission member 211 causes the elastic member 230 to generate a tensile elastic force between the transmission member 211 and the moving member 300; (2) the second gear 216 is not engaged with the transmission member 211, no driving force acts on the transmission member 211, and since the moving member 300 is already actuated at this time, the elastic member 230 still has an elastic force between the transmission member 211 and the moving member 300, and can perform resilient return on the actuation of the moving member 300 under the action of the elastic force; (3) in the above (2) and the above-mentioned rotatable arrangement of the output shaft 212 on the transmission member 211, the process of the moving member 300 rebounding due to the elastic force can be adjusted more flexibly by the power of driving the output shaft 212 or the rotatability of the output shaft 212. Thus, a more accurate pressure regulation process is achieved.

The pressing member 420 is rotatably connected to the clamping body 410, as shown in fig. 12, at least one through hole 412 communicating with the accommodating cavity 411 is formed in the clamping body 410, and the pressing member 420 is provided with protrusions 421 corresponding to the through holes 412. Fig. 12 shows that the clamping body 410 is provided with two through holes 412, and fig. 12 shows that the pressing member 420 is provided with two protrusions 421. During the rotation of the pressing member 420, the protrusion 421 can pass through the through hole 412 and form a clamping space with the inner wall of the receiving cavity 411 for clamping the processing tool 20. So, through the rotation that compresses tightly piece 420 and the tight effect of clamp that bulge 421 can produce machining tool 20, the structure is succinct, has realized being convenient for to change machining tool 20, has avoided pressing from both sides when tight machining tool 20 because of using a plurality of parts that compress tightly complex operation, the problem of breaking down easily has improved the reliability.

Specifically, in some embodiments, as shown in fig. 13 and 14, the rotation center line L2 of the protrusion 421 is parallel to or coincides with the rotation center line L3 of the rotation shaft 430.
