[0042] The utility model proposes a sliding structure 100, which is applied to a processing device 1000. The processing device 1000 is provided with a track structure 210. The sliding structure 100 can be used to fix a processing head 300 of the processing device 1000 and is slidably connected to the track structure 210, thereby driving the processing head 300 to move.

[0043] Combined with reference Figures 1 to 4 In some embodiments of the present application, the sliding structure 100 includes:

[0044] A motion bracket 10, wherein the motion bracket 10 has two sides arranged opposite to each other;

[0045] A first pulley 20 and a second pulley 30, wherein the first pulley 20 and the second pulley 30 are respectively disposed on two opposite sides of the moving bracket 10;

[0046] The movable member 40 is rotatably connected to at least one of the first pulley 20 and the second pulley 30 . The movable member 40 is slidably disposed on the motion bracket 10 to adjust the distance between the first pulley 20 and the second pulley 30 .

[0047] The sliding structure 100 proposed in the present application is used in a processing equipment 1000, and is mainly used to fix a processing head 300 or other structures that need to be translated; wherein the processing equipment 1000 may be, but is not limited to, a knife processing equipment 1000 such as a mechanical engraving machine, a mechanical drilling machine, or a laser processing equipment 1000 such as a laser engraving machine, a laser cutting machine, a laser marking machine, or a 3D printing device, etc. The structure or component that needs to be translated may be a processing head 300 such as a laser head or a print head, or may be a sensor such as a distance detector or other components, which is not limited here.

[0048] The sliding structure 100 includes a moving bracket 10 and a pulley block arranged on opposite sides of the moving bracket 10, each pulley block includes at least one rotatable pulley; when the sliding structure 100 is applied to a processing device 1000, two guide members 211 arranged side by side are correspondingly arranged on the processing device 1000, and the guide member 211 can be a guide rail or an optical axis, so that the guide member 211 is extended along the direction to be slidable, at this time, the first pulley 20 and the second pulley 30 can be located between the two guide members 211, and the first pulley 20 and the second pulley 30 can be arranged between the two guide members 211. The wheels 30 are slidably arranged on the corresponding guide members 211 respectively; the two guide members 211 can also be located on the inner side of the first pulley 20 and the second pulley 30, so that the first pulley 20 and the second pulley 30 can slide on the corresponding guide members 211, and when the sliding structure 100 slides along the guide members 211, the pulleys roll, so that the friction between the sliding structure 100 and the guide members 211 is rolling friction, which reduces the friction force of the sliding structure 100 during the sliding process, reduces friction loss, and is also conducive to improving the stability of the sliding process.

[0049] In addition, in the present embodiment, at least one of the first pulley 20 and the second pulley 30 in the sliding structure 100 is arranged on the movable part 40, so that it can move in the direction close to or away from the other pulley to adjust the distance between the first pulley 20 and the second pulley 30. When the pulley structure is applied to the processing equipment 1000 and slides with the two guide members 211, the distance between the first pulley 20 and the second pulley 30 can be adjusted according to the spacing between the two guide members 211, so that the first pulley 20 and the second pulley 30 are always close to the corresponding guide members 211; wherein, a driving member such as a motor or a hydraulic cylinder or a pneumatic cylinder can be set to drive the movable part 40 to drive the pulley to move to adjust the distance between the two pulleys, or an elastic member 42 can be set in the following embodiment to adjust the distance between the two pulleys through the movement of the elastic member 42, which is not limited here.

[0050] Therefore, it can be understood that the technical solution of the present invention enables at least one of the first pulley 20 and the second pulley 30 on both sides of the sliding structure 100 to be on one end of the movable bracket 10 so that the distance between the first pulley 20 and the second pulley 30 can be changed, so that the corresponding pulley position can be adjusted according to the position of the guide member 211 of the track structure 210 that cooperates with the pulley, so that the first pulley 20 and the second pulley 30 can always maintain contact with the guide member 211, making the sliding process more stable.

[0051] Please refer to Figure 4 In some embodiments of the present application, the motion bracket 10 has two surfaces arranged back to back, the first pulley and the second pulley are rotatably arranged on one of the surfaces, and the other surface serves as a mounting surface.

[0052] In this embodiment, the motion bracket 10 has two surfaces arranged back to back. The motion bracket 10 is roughly a plate-shaped structure, so that one of the surfaces is used to install the processing head 300 waiting for the installation structure, so that the pulley is set on the surface away from the installation surface. In this way, structures such as pulleys and guide members 211 are hidden on the back side of components such as the processing head 300. In some embodiments, components such as the processing head 300 need to be raised and lowered during operation to operate on processing surfaces at different heights. Structures such as pulleys and guide members 211 are hidden on the back side of components such as the processing head 300 to avoid interference between structures such as pulleys and processing heads 300, etc., thereby improving the stability and safety of the working process of the processing equipment 1000.

[0053] Please refer to Figure 4 In some embodiments of the present application, the first pulley 20 is rotatably connected to the movable member 40, and the second pulley 30 is rotatably connected to the moving bracket 10;

[0054] Alternatively, the sliding structure 100 is provided with at least two movable members 40 , and the first pulley 20 and the second pulley 30 are rotatably connected to the two movable members 40 , respectively.

[0055] In this embodiment, at least one of the first pulley 20 and the second pulley 30 in the sliding structure 100 is arranged on the movable member 40. It is possible that only the first pulley 20 is arranged on the movable member 40, and the first pulley 20 is moved closer to or farther away from the second pulley 30 to adjust the distance between the first pulley 20 and the second pulley 30. It is also possible that the first pulley 20 and the second pulley 30 are arranged on different movable members 40, so that the first pulley 20 and the second pulley 30 can be movably arranged to move closer to or farther away from each other, wherein the first pulley 20 and the second pulley 30 can be moved at the same time, or one of the pulleys can be moved according to actual needs, which is not limited here, thereby improving the flexibility of adjusting the distance between the first pulley 20 and the second pulley 30.

[0056] Please refer to Figure 5 In some embodiments of the present application, the movable member 40 includes a slider 41 , the moving bracket 10 is provided with a slide groove 11 , and the slider 41 is disposed in the slide groove 11 and slides along an extension direction of the slide groove 11 .

[0057] In this embodiment, the movable member 40 includes a slider 41 for carrying a pulley, and a slide groove 11 is provided in the motion bracket 10, and the slide groove 11 extends along the arrangement direction of the first pulley 20 and the second pulley 30, so that the slider 41 can be slidably provided in the slide groove 11. In this way, the slide groove 11 is used to limit and guide the slider 41 to prevent the slider 41 from being displaced during the sliding process relative to the motion bracket 10, so that the pulley and the guide member 211 maintain good contact and make the sliding process more stable. Among them, the slide groove 11 can be closed at both ends, or one end can be through to the edge of the motion bracket 10 in the following embodiment.

[0058] It should be noted that, in some embodiments, at least two pulleys are provided on each side of the sliding structure 100, for example, at least two first pulleys 20 are provided, and at least two second pulleys 30 may also be provided. In this case, at least two first pulleys 20 or at least two second pulleys 30 may be provided on the same slider 41, or each first pulley 20 or second pulley 30 may be provided on a slider 41, which is not limited here.

[0059] Please refer to Figure 5 In some embodiments of the present application, the movable member 40 further includes an elastic member 42, one end of the elastic member 42 is connected to the slider 41 and the other end is connected to the slide groove 11, and the elastic member 42 is used to apply a force to the slider 41 to slide in the slide groove 11.

[0060] In this embodiment, the movable part 40 also includes an elastic part 42 connected to the sliding part. When both ends of the slide groove 11 are closed, the elastic part 42 can be arranged on the side of the slider 41 away from the other pulley, that is, the elastic part 42 is arranged between the slider 41 and the end groove wall of the slide groove 11 away from the other pulley, or the elastic part 42 can be arranged on the side of the slider 41 facing the other group of pulleys, that is, the elastic part 42 is arranged between the slider 41 and the end groove wall of the slide groove 11 close to the other pulley; with such arrangement, when the sliding structure 100 cooperates with the track structure 210, the guide part 211 applies a force to the pulley to cause the elastic part 42 to produce elastic deformation. The elastic part 42 can be in a compressed state to elastically press the slider 41, or in a stretched state to pull the slider 41 to provide a force for the slider 41 to move along the slide groove 11. For example, taking the two pulley groups located between the two guide members 211 as an example, the guide member 211 applies pressure to the pulley to deform the elastic member 42. At this time, if the elastic member 42 is arranged on the side of the pulley facing the guide member 211, the elastic member 42 is stretched when the pulley is under pressure; if the elastic member 42 is arranged on the side of the pulley away from the guide member 211, the elastic member 42 is compressed when the pulley is under pressure. At this time, when the two guide members 211 are always kept parallel, the distance between the pulley and the guide member 211 remains unchanged and they are always in contact. When the distance between the two guide members 211 changes, if the distance between the two guide members 211 increases, a gap will be generated between one of the guide members 211 and the pulley on that side. At this time, the elastic member 42 will recover without being squeezed and move the pulley until the pulley is close to the guide member 211 again. For example, if the elastic member 42 is stretched when the pulley is under pressure, when a gap is generated between the guide member 211 and the pulley and the pulley is not under force, the elastic member 42 retracts to pull the pulley to move so that the pulley is close to and close to the guide member 211. If the elastic member 42 is compressed when the pulley is under pressure, when a gap is generated between the guide member 211 and the pulley and the pulley is not under force, the elastic member 42 stretches to push the pulley out so that the pulley is close to and close to the guide member 211; if the distance between the two guide members 211 is reduced, the guide member 211 will squeeze the elastic member 42 so that the elastic member 42 continues to produce elastic deformation and the two groups of pulleys are close to each other, so that a suitable contact force is maintained between the pulley and the guide member 211 to avoid excessive abutment force between the pulley and the guide member 211, which may cause the pulley to roll on the guide member 211 and make the sliding of the sliding structure 100 more stable.

[0061] Similarly, if the two guide members 211 are located between the two pulleys, when the distance between the two guide members 211 increases, the pulleys will be pushed to deform the elastic member 42 and increase the distance between the two pulley sets. When the distance between the two guide members 211 decreases, the elastic member 42 will drive the two pulleys closer to each other to maintain stable contact with the guide members 211, thereby improving the stability of the sliding process of the sliding structure 100. The elastic member 42 can be, but is not limited to, a spring, an elastic ejector pin, an elastic airbag, etc.

[0062] Please refer to Figure 5 In some embodiments of the present application, the elastic member 42 is disposed on a side of the slider 41 close to another pulley, and the elastic member 42 is used to apply a force to the slider 41 away from the slide groove 11.

[0063] The technical solution of the present application enables the elastic member 42 to be in an elastic deformation state when the sliding structure 100 is applied in the processing equipment 1000, so that the elastic member 42 can be used to elastically adjust the position of the pulley block so that the pulley block always keeps in contact with the guide member 211. In this embodiment, the elastic member 42 is arranged in the slide groove 11 and is located on the side of the slider 41 facing the other pulley block. When the sliding structure 100 is applied in the processing equipment 1000, the two pulley blocks are located between the two guide members 211 and the elastic member 42 is in a partially contracted state, so that when the distance between the two guide members 211 changes, the elastic member 42 can be restored to extend or continue to compress so that the pulley block always keeps in contact with the guide member 211. In this embodiment, the elastic member 42 is arranged on the side of the slider 41 close to the other pulley, and the elastic member 42 is in a compressed state. This arrangement can ensure that the slider 41 is always subjected to the elastic force of the elastic member 42, so that the slider 41 has a tendency to move away from the other pulley, thereby maintaining a good fit between the pulley connected to the slider 41 and the guide member 211.

[0064] Please refer to Figure 5 In some embodiments of the present application, a limiting hole 13 is provided on the side wall of the end of the slide groove 11, and part of the elastic member 42 is disposed in the limiting hole 13;

[0065] And / or, a mounting hole 411 is formed on a side wall of the sliding block 41 facing the end of the sliding groove 11 , and a portion of the elastic member 42 is disposed in the mounting hole 411 .

[0066] In this embodiment, a limiting hole 13 for installing the elastic member 42 is opened on the groove wall at the end of the slide groove 11, and part of the elastic member 42 is installed in the limiting hole 13. Such a configuration can improve the position stability of the elastic member 42 between the installation of the slider 41 and the movement, and prevent the elastic member 42 from falling off, so as to ensure that the elastic member 42 can always provide elastic force to the slider 41. At the same time, the limiting hole 13 can be used to avoid the elastic member 42, so as to prevent the elastic member 42 from occupying a longer space in the slide groove 11 and affecting the sliding distance of the slider 41.

[0067] Similarly, in some embodiments, a mounting hole 411 is opened on the side wall of the slider 41, and part of the elastic member 42 is arranged in the mounting hole 411. Such a setting can improve the position stability of the elastic member 42 between the installation on the slider 41 and the movement, and prevent the elastic member 42 from falling off, so as to ensure that the elastic member 42 can always provide elastic force to the slider 41. At the same time, the mounting hole 411 can be used to avoid the elastic member 42, so as to prevent the elastic member 42 from occupying a longer space in the slide groove 11 and affecting the sliding distance of the slider 41.

[0068] Of course, the limiting hole 13 and the mounting hole 411 can be simultaneously opened on the groove wall of the sliding groove 11 and the side wall of the sliding block 41, which can better limit the elastic member 42 and prevent the elastic member 42 from falling off.

[0069] Combined with reference Figure 6 and Figure 7 In some embodiments of the present application, the side wall of the slide groove 11 is provided with one of the plug-in groove 14 and the plug-in portion 412, and the side wall of the slider 41 is provided with the other of the plug-in groove 14 and the plug-in portion 412. The plug-in groove 14 extends along the length direction of the slide groove 11, and the plug-in portion 412 is inserted in the plug-in groove 14 and can slide along the plug-in groove 14.

[0070] The technical solution of the present application enables one of the pulleys in the sliding structure 100 to be arranged in a translational manner, and the pulley on the pulley group is arranged on the motion bracket 10 through the sliding cooperation of the slider 41 and the slide groove 11. In this embodiment, a matching structure of the plug-in portion 412 and the plug-in groove 14 is arranged between the groove side wall of the slide groove 11 and the side wall of the slider 41. The plug-in groove 14 extending along the length direction of the slide groove 11 can be opened on the groove side wall of the slide groove 11, and the plug-in portion 412 is convexly arranged on the side wall of the slider 41. The plug-in portion 412 can be any shape that is compatible with the plug-in groove 14, such as cylindrical, sheet-shaped, or block-shaped, which is not limited here; in addition, a plug-in portion 412 can be opened on the side wall of the slider 41. The slot 14 has a protruding connecting portion 412 on the side wall of the slot 11 and extending in the length direction of the slot 11; the connecting portion 412 is also inserted into the connecting slot 14. When the slider 41 slides in the slot 11, the connecting portion 412 and the connecting slot 14 also slide relatively. The connection between the slider 41 and the motion bracket 10 can be improved to prevent the slider 41 from being separated from the slot 11, thereby improving the stability of the overall structure.

[0071] Please refer to Figure 4 and Figure 5 In one embodiment of the present application, the sliding structure 100 also includes a stopper 43, a first portion of the stopper 43 is fixedly connected to the moving bracket 10, a second portion of the stopper 43 is arranged corresponding to the outlet of the slide groove 11, and is connected to the movable member 40; the stopper 43 is elastic.

[0072] In this embodiment, one end of the slide groove 11 is passed through to the edge of the moving bracket 10, and a stopper 43 is fixed on the side of the moving bracket 10. The stopper 43 is generally in the shape of a long strip and has a certain elasticity. The stopper 43 is defined to have a first part and a second part connected to each other. The first part is arranged opposite to and fixedly connected to the side of the moving bracket 10, and the second part is covered at the end opening of the slide groove 11 and connected to the slider 41. In this way, the slider 41 can be restricted by the stopper 43 to prevent the slider 41 from escaping from the slide groove 11. On the other hand, the stopper 43 can be elastically bent and deformed into the slide groove 11 or outside the slide groove 11, thereby providing elastic force for the slider 41. For example, when the pulley is bent and deformed by the pressure of the guide member 211, the stopper 43 provides elastic force to the slider 41. When the distance between the two guide members 211 changes, the stopper 43 is restored and the slider 41 can drive the pulley to slide along the slide groove 11 under the action of the elastic force to adjust the distance between the first pulley 20 and the second pulley 30, so that the pulley is close to the guide member 211 again. The stopper 43 and the slider 41 or the motion bracket 10 can be connected by a locking member 44 such as a bolt, or by bonding, welding, etc., which is not limited here.

[0073] Please refer to Figure 5 In one embodiment of the present application, a side edge of the motion bracket 10 facing the stopper 43 is provided with an avoidance groove 12 , one end of the avoidance groove 12 is connected to the slide groove 11 , and the groove depth of the avoidance groove 12 is less than the groove depth of the slide groove 11 .

[0074] In this embodiment, an avoidance groove 12 is opened on one side of the slide groove 11, so as to form an avoidance space between the stopper 43 and the movement. Such a configuration increases the length of the stopper 43 that can bend and deform toward the inside of the slide groove 11, thereby increasing the depth that the slider 41 can slide toward the inside of the slide groove 11, and increasing the sliding range of the slider 41, thereby increasing the adjustment range of the distance between the first pulley 20 and the second pulley 30, so that the sliding structure 100 can be suitable for track structures 210 of different sizes, thereby improving the applicability of the sliding structure 100.

[0075] Please refer to Figure 4 In some embodiments of the present application, a limiting groove 21 is provided on the circumferential side of the first pulley 20, and the limiting groove 21 is arranged around the circumference of the first pulley 20;

[0076] And / or, a second limiting groove 31 is formed on the circumferential side of the second pulley 30 , and the second limiting groove 31 is arranged around the circumference of the second pulley 30 .

[0077] In this embodiment, a first limiting groove 21 is opened on the circumferential side of the first pulley 20, and the limiting groove 21 is arranged around the circumference of the pulley. With this arrangement, when the sliding structure 100 is used in the processing equipment 1000 and cooperates with two guide members 211 arranged side by side, the guide member 211 can be arranged in the first limiting groove 21 to improve the connection strength between the first pulley 20 and the guide member 211, and further reduce the risk of the first pulley 20 falling off the guide member 211. The setting of the first limiting groove 21 can also guide the rolling of the first pulley 20 on the guide member 211, and avoid the first pulley 20 from being displaced and separated from the guide member 211 during the rolling process, thereby improving the stability of the sliding structure 100 during the sliding process.

[0078] Similarly, a second limiting groove 31 is opened on the circumferential side of the second pulley 30, and the second limiting groove 31 is arranged around the circumference of the pulley. With such an arrangement, when the sliding structure 100 is used in the processing equipment 1000 and cooperates with two guide members 211 arranged side by side, the guide member 211 can be arranged in the second limiting groove 31 to improve the connection strength between the second pulley 30 and the guide member 211, and further reduce the risk of the second pulley 30 falling off the guide member 211. The setting of the second limiting groove 31 can also guide the rolling of the second pulley 30 on the guide member 211, and avoid the second pulley 30 from being displaced and separated from the guide member 211 during the rolling process, thereby improving the stability of the sliding process of the sliding structure 100.

[0079] Please refer to Figure 1 and Figure 2 The present application also proposes a processing device 1000, which includes:

[0080] The device body 200 is provided with two guide members 211 arranged side by side;

[0081] As in the sliding structure 100 in any of the above embodiments, the first pulley 20 of the sliding structure 100 rolls with one of the guide members 211 , and the second pulley 30 of the sliding structure 100 rolls with the other guide member 211 ; and

Among them, the equipment body 200 of the processing equipment 1000 is provided with two guide members 211 arranged side by side as a guide structure and a support structure. The guide member 211 can be a guide rail or an optical axis, so that the guide member 211 is extended along the direction in which it is required to slide. In addition, a sliding structure 100 is provided for fixing and installing the processing head 300. The specific structure of the sliding structure 100 refers to any of the aforementioned embodiments. The sliding structure 100 includes a moving bracket 10 and a first pulley 20 and a second pulley 30 arranged on opposite sides of the moving bracket 10; it can be such that the first pulley 20 and the second pulley 30 are located on the two guide members. 211, and the first pulley 20 and the second pulley 30 are slidably arranged on the corresponding guide members 211 respectively; it is also possible that the two guide members 211 are located at the inner sides of the first pulley 20 and the second pulley 30, and the first pulley 20 and the second pulley 30 can also slide on the corresponding guide members 211, and when the sliding structure 100 slides along the guide members 211, the pulleys roll, so that the friction between the sliding structure 100 and the guide members 211 is rolling friction, which reduces the friction force suffered by the sliding structure 100 during the sliding process, reduces friction loss, and is also conducive to improving the stability of the sliding process.

[0084] In addition, at least one of the first pulley 20 and the second pulley 30 in the sliding structure 100 is arranged on the movable part 40, so that it can move in the direction close to or away from the other pulley to adjust the distance between the first pulley 20 and the second pulley 30. When the pulley structure is applied to the processing equipment 1000 and slides with the two guide members 211, the distance between the first pulley 20 and the second pulley 30 can be adjusted according to the spacing between the two guide members 211, so that the first pulley 20 and the second pulley 30 are always close to the corresponding guide members 211; wherein, a driving member such as a motor or a hydraulic cylinder or a pneumatic cylinder can be set to drive the movable part 40 to drive the pulley to move to adjust the distance between the two pulleys, or an elastic member 42 can be set in the following embodiment to adjust the distance between the two pulleys through the movement of the elastic member 42, which is not limited here.

[0085] Please refer to Figure 3 In some embodiments of the present application, the first pulley 20 and the second pulley 30 are disposed between the two guide members 211 .

[0086] In this embodiment, the first pulley 20 and the second pulley 30 are located between the two guide members 211, so that the two guide members 211 are used to limit the first pulley 20 and the second pulley 30, so that the connection between the sliding structure 100 and the guide members 211 is more stable and not easy to fall off.
