Description

Technical Field

[0001] The present invention relates to the technical field of cutting, and particularly relates to a folding cutting device and a using method thereof. Background Art

[0002] In the tobacco industry, a maintenance room is usually equipped in a tobacco production workshop to repair faulty tobacco equipment. During the repair process of faulty tobacco equipment, various maintenance operation platforms are required, such as a cutting operation table with a cutting function. The cutting operation table with a cutting function is specifically used to process the distorted trusses in faulty tobacco equipment. That is, when replacing the distorted trusses in faulty tobacco equipment, maintenance workers will first base on the specifications of the trusses that were not distorted before in the faulty tobacco equipment, and then use the cutting operation table with a cutting function to cut the intersection angles of the profiles that make up the truss. Then, one end of the profile with the cut angle is spliced with one end of another profile with a cut angle, and then a connecting sleeve and bolts are used to firmly connect the splicing part of the two profiles. By repeating this process, the overall framework of the truss in the tobacco equipment is fabricated. Finally, the distorted truss is removed from the faulty tobacco equipment, and a new truss is replaced on the faulty tobacco equipment.

[0003] The above-mentioned cutting operation table with a cutting function can complete the process of cutting profiles. However, in the actual use process of the existing cutting operation table with a cutting function, there are still the following defects: (1) Since the overall size of the cutting operation table with a cutting function is large and it is not convenient to store, and considering the limited maintenance space in the maintenance room itself, the maintenance and repair of tobacco equipment in a maintenance room with limited space will be restricted to a certain extent, that is, it is not conducive to the development of other maintenance activities; (2) The cutting blade angle in the existing cutting operation table with a cutting function cannot be adjusted. When cutting the inclined angle of the profile, the profile can only be inclined at a certain angle for cutting. Therefore, the processing means of the cutting operation table with a cutting function is relatively single, which reduces the practicability of the equipment.

[0004] Therefore, it is necessary to improve the overall structure of the cutting operation table to solve the problems that the existing cutting operation table with a cutting function is not convenient to store, not conducive to the development of other maintenance activities, and the processing means of the existing cutting operation table with a cutting function is relatively single.

Detailed implementation manners

[0049] As Figure 1-17As shown below, to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0050] Embodiment

[0051] For the existing cutting operation table with a cutting function, although it can complete the process of cutting profiles, in the actual use process of the existing cutting operation table with a cutting function, the following defects still exist: (1) Since the overall size of the cutting operation table with a cutting function is large and it is not convenient to store, and considering the limited maintenance space in the maintenance room itself, maintaining and servicing tobacco equipment in a maintenance room with limited space will be restricted to a certain extent, that is, it is not conducive to the development of other maintenance activities.

[0052] (2) The angle of the cutting blade in the existing cutting operation table with a cutting function cannot be adjusted. When cutting profiles at an inclined angle, the profiles can only be inclined at a certain angle for cutting. Therefore, the processing means of this cutting operation table with a cutting function are relatively single, which reduces the practicability of the equipment.

[0053] Therefore, this application proposes a folding cutting device and its usage method to solve the problems that the existing cutting operation table with a cutting function is inconvenient to store, not conducive to the development of other maintenance activities, and the processing means of the existing cutting operation table with a cutting function are relatively single.

[0054] Specifically, in the first aspect of this application, a folding cutting device is proposed. Please refer to Figure 1 and Figure 2 . A folding cutting device includes a support foot 1, a cutting workbench 2, an angle-adjustable cutting member 3 and an adjustable member 5; one end of the support foot 1 away from the ground is rotatably and adjustably connected to the bottom of the cutting workbench 2. The cutting end of the angle-adjustable cutting member 3 passes through a through groove 4 opened at the top of the cutting workbench 2 and extends out. One end of the angle-adjustable cutting member 3 is rotatably and adjustably connected to one inner side wall of the cutting workbench 2, and the other end of the angle-adjustable cutting member 3 is rotatably and adjustably connected to the other inner side wall of the cutting workbench 2 through the adjustable member 5.

[0055] In actual operation, when cutting the profiles used in the truss of a faulty tobacco equipment in the repair room, the foldable cutting device stored in the corner of the repair room can be placed at a suitable position in the repair room, and the four support feet 1 pre-stored at the bottom of the cutting workbench 2 can be unfolded to support the entire cutting workbench 2 (support the entire cutting workbench 2: keep the foldable cutting device in a standing posture). Then, according to the angle to be cut for the profiles used in the truss, the adjustable member 5 provided on the side of the cutting workbench 2 is adjusted to adjust the angle-adjustable cutting member 3 on the cutting workbench 2 to a suitable cutting angle. Then, the profile to be cut is pushed towards the cutting end direction of the angle-adjustable cutting member 3 with a pre-adjusted angle on the top of the cutting workbench 2. The running angle-adjustable cutting member 3 will cut the profile to be cut into the profile to be cut that meets the requirements. Subsequently, the profile with the cut angle and the scraps on the top of the cutting workbench 2 are collected. Then, the support feet 1 on the top of the cutting workbench 2 are folded to fit with the bottom of the cutting workbench 2. Finally, the foldable cutting device with the support feet 1 stored is taken to the corner of the repair room for placement; in this way, on the one hand, when the foldable cutting device is not used for cutting, the support feet in the foldable cutting device can be folded and the foldable cutting device with the folded support feet 1 can be stored in the corner of the repair room to save the space of the repair room for other maintenance activities of the tobacco equipment machinery to be carried out; on the other hand, when the profile is cut into the required cutting bevel angle, the inclination angle of the profile can be cut by adjusting the cutting end angle of the angle-adjustable cutting member 3, and the profile can also be inclined at a certain angle and cut with the angle-adjustable cutting member without adjusting the cutting angle. In this way, the two cutting processing methods make the processing means no longer single, so as to solve the problems that the existing cutting operation table with cutting function is inconvenient to store and is not conducive to the development of other maintenance activities, and the processing means of the existing cutting operation table with cutting function is relatively single.

[0056] Please refer to Figure 3 , to ensure that the support feet 1 in the unfolded state can stably support the cutting workbench 2, the support feet 1 include an L-shaped adjustable seat 44, a support leg 6 and a first locking bolt 7; among them, the L-shaped adjustable seat 44 and the first locking bolt 7 cooperate to temporarily lock the support feet 1 converted from the folded state to the unfolded state. On the one hand, it ensures that the unfolded support feet 1 stably support the cutting workbench, and on the other hand, it realizes the function of rotatable adjustment connection between one end of the support feet 1 away from the ground and the bottom of the cutting workbench 2; the support leg is used to support the cutting workbench 2, facilitating the subsequent work of cutting profiles on the cutting workbench 2.

[0057] Specifically, two L-shaped adjustable seats 44 are symmetrically arranged at the bottom of the cutting workbench 2. A space one 8 for the rotation of the support feet 6 is defined between the two L-shaped adjustable seats 44. Part of the support feet 6 are located in the space one 8 for the rotation of the support feet 6 and are rotatably connected to the bottom of the cutting workbench 2. The bolt rod of the first locking bolt 7 passes through the arc-shaped adjustment slot 9 on the side wall of the L-shaped adjustable seat 44 and is threadedly connected to the threaded hole opened on the side wall of the support foot 6. The nut of the first locking bolt 7 abuts against the surface of the notch of the arc-shaped adjustment slot 9 opened on the side wall of the L-shaped adjustable seat 44. The arc-shaped adjustment slot 9 is an arc-shaped through slot. The width of the arc-shaped through slot is greater than the outer diameter of the bolt rod of the first locking bolt 7, and the width of the arc-shaped through slot is less than the diameter of the nut of the first locking bolt 7.

[0058] In actual use, after the support feet 6 pre-stored at the bottom of the cutting workbench 2 are unfolded to a position at a 90° angle to the bottom of the cutting workbench 2, the bolt rod of the first locking bolt 7 can be passed through the arc-shaped adjustment slot 9 on the side wall of the L-shaped adjustable seat 44 and threadedly connected to the threaded hole opened on the side wall of the support foot 6. Then, the first locking bolt 7 is turned to make the nut of the first locking bolt 7 tightly abut against the surface of the notch of the arc-shaped adjustment slot 9 opened on the side wall of the L-shaped adjustable seat 44, so as to lock the support feet 6 at a 90° angle to the bottom of the cutting workbench 2, avoid the support feet 6 rotating randomly around the bottom of the cutting workbench 2, which affects the subsequent cutting of profiles on the cutting workbench, and indirectly improve the stability of the support of the support feet 6 for the cutting workbench 2.

[0059] When folding and retracting the support feet 6 at a 90° angle to the bottom of the cutting workbench 2, the first locking bolt 7 at the arc-shaped adjustment slot 9 on the side wall of the L-shaped adjustable seat 44 can be turned to make the nut of the first locking bolt 7 not abut against the surface of the notch of the arc-shaped adjustment slot 9 opened on the side wall of the L-shaped adjustable seat 44. Then, the support feet 6 are pulled and folded into the cutting workbench 2. When the support feet 6 are folded and located at the bottom of the cutting workbench 2, the first locking bolt 7 is turned again to make the nut of the first locking bolt 7 tightly abut against the surface of the notch of the arc-shaped adjustment slot 9 opened on the side wall of the L-shaped adjustable seat 44, so as to lock the position of the support feet 6 with the bottom of the cutting workbench 2 at this time, avoid the support feet 6 rotating around the bottom of the cutting workbench 2 during the handling of the folding cutting device, and prevent the situation that it is inconvenient to move the folding cutting device.

[0060] It should be noted that part of the support feet 6 are located in the space one 8 for the rotation of the support feet 6 and are rotatably connected to the bottom of the cutting workbench 2, that is, the support feet 6 located in the space one 8 are rotatably connected to the L-shaped adjustable seats 44. This means that when the support feet 6 rotate from the space one 8 defined between the two L-shaped adjustable seats 44 for the rotation of the support feet 6, they are not interfered by the two L-shaped adjustable seats 44.

[0061] It should be noted that the nut in the first locking bolt 7 abuts against the surface of the notch of the arc-shaped adjustment groove 9 opened on the side wall of the L-shaped adjustable seat 44. That is, when the first locking bolt 7 locks the deployed support feet, the nut in the first locking bolt 7 is in a state of abutting against the surface of the notch of the arc-shaped adjustment groove 9 opened on the side wall of the L-shaped adjustable seat 44; when the first locking bolt 7 does not lock the deployed support feet, the nut in the first locking bolt 7 is not in a state of abutting against the surface of the notch of the arc-shaped adjustment groove 9 opened on the side wall of the L-shaped adjustable seat 44.

[0062] It should be noted that the cutting workbench 2 is a rectangular structural frame with one side wall closed, three side walls open, and the top closed.

[0063] Please refer to Figure 3 , to facilitate maintenance workers of different heights to use the folding cutting device to cut profiles, the support feet 6 for adjusting the height of the folding cutting device include a support foot column 10, an adjustment sleeve 11, a locking handle 43 with a threaded rod, and a base 12; among them, the support foot column 10 is used for rotatably connecting with the bottom of the cutting workbench 2; the adjustment sleeve 11 is used for slidably connecting with the other end of the support foot column 10 to adjust the overall height of the folding cutting device; the locking handle 43 with a threaded rod is used for temporarily locking the support foot column 10 that has moved up or down in place in the adjustment sleeve 11.

[0064] Specifically, the threaded hole is opened on the side wall of the support foot column 10 near the bottom of the cutting workbench 2. One end of the support foot column 10 away from the ground passes through the space 8 defined between the two L-shaped adjustable seats 44 and is rotatably connected with the bottom of the cutting workbench 2. That is, an internal threaded hole is opened on the side wall of the adjustment sleeve 11. One end of the threaded rod in the locking handle 43 with a threaded rod is threadedly connected to the internal threaded hole on the outer wall of the adjustment sleeve 11 and extends into the adjustment sleeve 11 to abut against the side wall of the support foot column 10 in the adjustment sleeve 11. The closed end of the adjustment sleeve 11 away from the support foot column 10 is connected to the top of the base 12.

[0065] In actual use, before cutting profiles with the folding cutting device in a standing posture (the folding cutting device in a standing posture: the support feet of the folding cutting device are deployed and support the folding cutting device), the locking handle 43 with a threaded rod can be turned so that one end of the threaded rod in the locking handle 43 does not abut against the support foot column 10 in the adjustment sleeve 11, and then move up or down along the adjustment sleeve 11 to a suitable position to move the overall height of the folding cutting device to a height suitable for the maintenance personnel to operate. Then, turn the locking handle 43 with a threaded rod again so that one end of the threaded rod in the locking handle 43 abuts against the support foot column 10 that has moved in place in the adjustment sleeve 11 for locking. In this way, it is convenient for maintenance workers of different heights to operate, indirectly improving the practicality of the folding cutting device.

[0066] Please refer to Figure 4, The angle-adjustable cutting member 3 for cutting profiles includes an angle grinder 13, a connecting seat 14 and a rotating arm 15; the angle grinder 13 is used for cutting profiles; the connecting seat 14 is used for mounting and fixing the angle grinder 13; the rotating arm 15 is used to drive the connecting seat 14 to rotate, indirectly causing the angle grinder 13 on the connecting seat 14 to rotate synchronously, so as to realize the angle adjustment of the angle-adjustable cutting member 3.

[0067] Specifically, the angle grinder 13 is located inside the cutting workbench 2, and the cutting blade 16 of the angle grinder 13 passes through and extends out from the through groove 4 opened on the cutting workbench 2. The fixed end of the angle grinder 13 is connected to the side wall of the connecting seat 14 located inside the cutting workbench 2. Both ends of the connecting seat 14 are respectively connected to one end of the rotating arm 15. One end of one rotating arm 15 is rotatably connected to one inner wall of the cutting workbench 2, and one end of the other rotating arm 15 is rotatably and adjustably connected to the other side wall of the cutting workbench 2 through the adjustable member 5.

[0068] In actual use, when using the angle-adjustable cutting member 3 to cut the angle of the profile, first adjust the adjustable member 5 to make the rotating arm 15 connected to one end of the adjustable member 5 in an active state with one inner wall of the cutting workbench 2. Then, according to the angle to be cut of the profile, adjust the adjustable member 5 to make the rotating arm 15 connected to one end of the adjustable member 5 rotate to the corresponding position, indirectly driving the connecting seat 14 connected through the rotating arm 15 to also rotate to the corresponding position. In this way, when the connecting seat 14 rotates to the corresponding position, the cutting blade 16 in the angle grinder 13 also offsets a certain position in the through groove 4, that is, the adjustment of the cutting angle of the angle grinder 13 is completed. Then, push the profile to be cut longitudinally flat towards the cutting blade 16 with the adjusted cutting angle, and the running cutting blade cuts the profile into the required cutting angle.

[0069] It should be noted that the angle grinder 13 is a prior art. In this application, the grinding disc on the angle grinder 13 is replaced with a cutting blade 16. As for other components of the angle grinder 13, no improvement or design is made to them, so their structures will not be described in detail.

[0070] The groove width between the through grooves 4 can satisfy the offset of the cutting blade 16 during the angle adjustment, that is, the offset cutting blade 16 will not interfere with the inner wall of the through groove 4. The cutting blade 16 is set as a circular blade, and the outer edge of the circular blade is serrated.

[0071] It should be noted that there is a certain clearance distance reserved between the connecting seat 14 and the inner wall of the cutting workbench 1 near the reference numeral 2 in Figure 7 to prevent the rotating connecting seat 14 from interfering with the inner wall of the cutting workbench 1 near the reference numeral 2 in Figure 7 when the connecting seat 14 rotates.

[0072] Please refer to Figure 5 、Figure 6 , Figure 8 , Figure 9 and Figure 10 , the adjustable member 5 for adjusting the cutting angle of the cutting blade 16 includes an adjusting screw 17 and an adjusting nut 45; wherein, the adjusting screw 17 is used to connect with one of the rotating arms 15, so as to drive one of the rotating arms 15 to rotate by moving the adjusting screw 17, and indirectly drive the connecting seat 14 connected by the rotating arm 15 to rotate, so that the cutting blade 16 in the angle grinder 13 on the connecting seat 14 deflects in the through groove 4; the adjusting nut 45 is used to lock the adjusting screw 17 in place after it has been moved, so that the cutting blade 16 with the adjusted cutting angle is temporarily held in the adjusted angle position.

[0073] Specifically, the adjusting screw 17 passes through a first arc-shaped groove 18 opened on one side wall of the cutting workbench 2 and is connected to a connecting column connected to the side wall of one of the rotating arms 15. One end of the adjusting screw 17 away from the side wall of one of the rotating arms 15 is threadedly connected to the adjusting nut 45. The adjusting nut 45 abuts against the outer side wall of the cutting workbench 2 provided with the first arc-shaped groove 18. The diameter of the adjusting nut 45 is larger than the width of the first arc-shaped groove 18, and the width of the first arc-shaped groove 18 is larger than the outer diameter of the adjusting screw 17.

[0074] In actual use, during the process of adjusting the cutting angle of the cutting blade 16 with the adjustable member 5, the adjusting nut 45 threadedly connected to the adjusting screw 17 can be turned, so that the rotating arm 15 connected to one end of the adjusting screw 17 through the connecting column is in an active state with one inner wall of the cutting workbench 2. Then, according to the angle to be cut of the profile, the adjusting screw 17 connected to the connecting column on the side wall of one of the rotating arms 15 is pulled along the first arc-shaped groove 18 to the corresponding position. At the same time, the connecting seat 14 connected to one of the rotating arms 15 also moves to the corresponding position, indirectly causing the cutting blade 16 in the angle grinder on the connecting seat 14 to deflect in the through groove 4. After the cutting blade 16 deflects to the corresponding position in the through groove 4, the adjusting nut 45 threadedly connected to the adjusting screw 17 is turned to abut against the side wall of the cutting workbench 2 provided with the first arc-shaped groove 18, so that the rotating arm 15 connected to one end of the adjusting screw 17 through the connecting column is in a temporarily locked state with one inner wall of the cutting workbench 2, indirectly locking the cutting blade 16 with the adjusted angle in place, so as to facilitate the subsequent operation of cutting the profile with the cutting blade 16 with the adjusted angle.

[0075] Please refer to Figure 8 and Figure 9, for referring to the adjusted angle of the cutting blade 16, a folding cutting device further includes a first angle adjustment reference member 19, which includes a sliding column 20, a first indicating needle 21 and a first angle marking arc strip 22; wherein, the sliding column 20 is used to connect with the side wall of the rotating arm 15 connected with the adjusting screw 17, so that when the adjusting screw 17 drives the rotating arm 15 to move to adjust the cutting angle of the cutting blade 16, the sliding column 20 connected with one of the rotating arms 15 also moves; the first indicating needle 21 is used to connect with the sliding column 20, so that when the sliding column 20 moves with the rotating arm 15, the first indicating needle 21 also moves; the first angle marking arc strip 22 is used to cooperate with the first indicating needle 21, so that when the first indicating needle 21 moves to a position corresponding to a certain position on the first angle marking arc strip 22 along with the sliding column 20, the cutting angle adjusted by the cutting blade 16 can be indirectly known through the angle parameter on the first angle marking arc strip 22.

[0076] Specifically, the sliding column 20 is slidably connected with a first arc groove 18 opened on the side wall of the cutting workbench 2. One end of the sliding column 20 is connected with the side wall of the rotating arm 15 connected with the adjusting screw 17, and the other end of the sliding column 20 extends out from the first arc groove 18 opened on the side wall of the cutting workbench 2 and is connected with the first indicating needle 21. The other end of the first indicating needle 21 corresponds to the angle parameter engraved on the first angle marking arc strip 22, and the first angle marking arc strip 22 is arranged around one side of the first arc groove 18 opened on the side wall of the cutting workbench 2 close to it.

[0077] In actual use, during the process of pulling the adjusting screw 17 to drive the connecting seat 14 connected with one of the rotating arms 15 to rotate, indirectly adjusting the angle of the cutting blade 16 in the angle grinder 13 on the connecting seat 14, for the angle to be adjusted by the cutting blade 16, referring to the angle parameter on the first angle marking arc strip 22, pulling the adjusting screw 17 connected with one of the rotating arms 15 to move along the first arc groove 18. At the same time, the sliding column 20 connected with the side wall of the rotating arm 15 connected with the adjusting screw 17 also moves along the first arc groove 18. When the first indicating needle 21 connected with the sliding column 20 moves to a position where the angle parameter on the first angle marking arc strip 22 is close to the angle to be adjusted by the cutting blade 16, screw the adjusting nut threadedly connected with the adjusting screw 17 to abut against the side wall of the cutting workbench 2 provided with the first arc groove 18, so that the rotating arm 15 connected with one end of the adjusting screw 17 through the connecting column is in a temporarily locked state with one of the inner walls of the cutting workbench 2, further improving the accuracy of adjusting the cutting angle of the cutting blade 16.

[0078] It should be noted that a distance is reserved between the first indicating needle 21 and the first angle marking arc strip 22, that is, when the first indicating needle 21 rotates, it will not interfere with the first angle marking arc strip 22.

[0079] Please refer to Figure 11, to facilitate the clamping of the profile to be cut for subsequent stable cutting of the profile, a folding cutting device further includes a profile to be cut guiding member 23 and a profile to be cut resisting member 24; the profile to be cut guiding member 23 includes a moving member 25 and a profile guiding member 26; wherein, the profile guiding member 26 is used to adjust the placement angle or placement orientation of the profile to be cut; the profile guiding member 26 and the profile to be cut resisting member 24 are clamped and cooperated to clamp the profile to be cut that is placed between the profile guiding member 26 and the profile to be cut resisting member 24 and has been adjusted in placement angle; the moving member 25 is used to drive the profile guiding member 26, the profile to be cut resisting member 24, and the profile to be cut that is clamped between the profile guiding member 26 and the profile to be cut resisting member 24 and has been adjusted in orientation, to move horizontally on the top of the cutting workbench 2 in a direction close to or away from the cutting blade 16.

[0080] Specifically, the profile to be cut guiding member 23 includes a moving member 25 and a profile guiding member 26. The moving member 25 is located on the cutting workbench 2 on the side close to the cutting blade 16. The moving member 25 moves along the cutting workbench 2. The profile guiding member 26 is rotationally and adjustably connected to the moving member 25. The profile to be cut resisting member 24 is located on the moving path of the profile to be cut guiding member 23. The distance between the profile to be cut resisting member 24 and the profile guiding member 26 is adjustably connected. A space two 27 for placing the profile to be cut is defined between the profile guiding member 26 and the profile to be cut resisting member 24. The profile to be cut resisting member 24 moves along the cutting workbench 2.

[0081] In actual use, when clamping the profile to be cut with the profile to be cut guiding member 23 and the profile to be cut resisting member 24 on the folding cutting device in a standing posture for subsequent cutting the profile to be cut into the required angle by the cutting blade 16, there are the following two processing means for cutting the profile. The first processing means is to adjust the angle of the cutting blade without adjusting the orientation or angle of the profile to be cut clamped between the profile guiding member 26 and the profile to be cut resisting member 24. The second processing means is to not adjust the angle of the cutting blade and adjust the orientation or angle of the profile to be cut clamped between the profile guiding member 26 and the profile to be cut resisting member 24.

[0082] Specifically, when cutting the profile to be cut with the first processing method (the first processing method adjusts the angle of the cutting blade and does not adjust the orientation or angle of the profile to be cut clamped between the profile guide 26 and the profile to be cut abutment 24), first adjust the cutting angle of the cutting blade 16 according to the previous steps of adjusting the cutting angle of the cutting blade 16. Then, adjust the profile guide 26 in the profile cutting guide 23 and the profile to be cut abutment 24 to be placed in parallel. Then, place the profile to be cut in a horizontal longitudinal posture between the profile guide 26 and the profile to be cut abutment 24. Next, adjust the profile to be cut abutment 24 to move the profile to be cut abutment 24 towards the profile guide 26 to clamp the profile to be cut pre-placed between the profile guide 26 and the profile to be cut abutment 24. Subsequently, push the moving member 25 towards the cutting blade 16 with the cutting angle pre-adjusted. The profile to be cut clamped between the profile guide 26 and the profile to be cut abutment 24 is then cut into the profile with the required angle by the rotating cutting blade 16. Then, push the moving member 25 to move to one side away from the cutting blade 16, and adjust the profile to be cut abutment 24 to move the profile to be cut abutment 24 away from the profile guide 26. Finally, take out the profile to be cut with the cut angle between the profile guide 26 and the profile to be cut abutment 24 to complete the process of cutting the profile with the first processing method.

[0083] When cutting the profile to be cut with the second processing method (the second processing method: does not adjust the angle of the cutting blade 16 and adjusts the orientation or angle of the profile to be cut clamped between the profile guide 26 and the profile to be cut abutment 24), first keep the cutting blade 16 parallel to the edge of the cutting workbench, that is, do not adjust the angle of the cutting blade 16. Then, adjust the profile guide 26 in the profile cutting guide 23 and the profile to be cut abutment 24 not to be placed in parallel. Then, place the profile to be cut according to the current placement posture of the profile guide 26 (placing according to the current placement posture of the profile guide 26: the profile to be cut is placed at a certain angle to the horizontal direction). Next, adjust the profile to be cut abutment 24 to move the profile to be cut abutment 24 towards the profile guide 26 to clamp the profile to be cut pre-placed between the profile guide 26 and the profile to be cut abutment 24. Subsequently, push the moving member 25 towards the cutting blade 16 without adjusting the cutting angle. The profile to be cut clamped between the profile guide 26 and the profile to be cut abutment 24 is then cut into the profile with the required angle by the rotating cutting blade 16. Then, push the moving member 25 to move to one side away from the cutting blade 16, and adjust the profile to be cut abutment 24 to move the profile to be cut abutment 24 away from the profile guide 26. Finally, take out the profile to be cut with the cut angle between the profile guide 26 and the profile to be cut abutment 24 to complete the process of cutting the profile with the second processing method.

[0084] In this way, when using this folding cutting device to cut the profile into the required angle, not only can the profile be cut by the first processing method described above, but also the profile can be cut by the second processing method described above, making the processing methods no longer single, so as to solve the problem that the processing methods of the existing cutting operation table with cutting function are relatively single.

[0085] Please refer to Figure 12 、 Figure 13 、 Figure 14 、 Figure 15 、 Figure 16 and Figure 17 , the guiding moving part 25 used to drive the profile guiding part 26 to move horizontally along the cutting workbench 2 or to move in a rotationally adjustable manner with the profile guiding part 26 includes a slide bar 28, a connecting shaft 29 and a first screw 30; wherein, the slide bar 28 is used for sliding connection with the chute 46 at the top of the cutting workbench 2 to drive the slide bar 28 and other components arranged on the top of the slide bar 28 to move horizontally along the cutting workbench 1; the profile guiding part 26 is rotatably connected with the connecting shaft 29, and the connecting shaft 29 is used for circumferentially rotating the profile guiding part 26; the first screw 30 is matched with a nut for temporarily locking the profile guiding part 26 that has rotated in place.

[0086] Specifically, the slide bar 28 is slidably connected with the chute 46 opened at the top of the cutting workbench 2, the bottom of the connecting shaft 29 is connected to the top of the slide bar 28, the profile guiding part 26 is rotatably connected with the connecting shaft 29, and the profile guiding part 26 is rotationally and adjustably connected to the top of the slide bar 28 through the first screw 30 and a nut threadedly connected with the first screw 30.

[0087] In actual use, when the guiding moving part 25 drives the profile guiding part 26 to move on the top of the cutting workbench 2 in the direction close to or away from the cutting blade 16, the slide bar 28 can be pushed to move horizontally to the right or left along the chute 46 at the top of the cutting workbench 2. Then, the profile guiding part 26 rotatably connected to the top of the slide bar 28 through the connecting shaft 29 also moves horizontally to the right or left along with the slide bar 28. In this way, the slide bar 28 slides and cooperates with the chute 46 at the top of the cutting workbench 2, making the movement of the profile guiding part 26 smoother.

[0088] When adjusting the placement posture of the profile guide 26 to the posture required for placing the profile to be cut subsequently, the nut threadedly connected to the first screw 30 can be turned to make the slide bar 28 and the profile guide 26 in an active state. Then, for the posture required for cutting the profile to be cut subsequently (the posture required for placing the profile to be cut: the posture facing the profile to be cut or the posture of the profile to be cut inclined to the horizontal direction), the profile guide 26 is rotated along the connecting shaft 29 to the corresponding position. Then, turn the nut threadedly connected to the first screw 30 to lock the profile guide 26 and the slide bar 28. Finally, place the profile to be cut against the side wall of the profile guide 26 with the adjusted placement posture to assist in placing the profile to be cut in the required cutting posture.

[0089] Please refer to Figure 12 、 Figure 13 、 Figure 14 、 Figure 15 、 Figure 16 and Figure 17 The profile guide 26 that is rotatably and adjustably connected to the connecting shaft 29 includes a rotating seat 31 and a guiding vertical plate 32. Among them, the rotating seat 31 is used for rotatably connecting to the connecting shaft 29 at the top of the slide bar 28; the guiding vertical plate 32 is used for connecting to the rotating seat 31 so that under the drive of the rotation of the rotating seat 31, the guiding vertical plate 32 is synchronously rotated to the corresponding position.

[0090] Specifically, the rotating seat 31 is rotatably connected to the connecting shaft 29, the side wall of the rotating seat 31 is connected to the side wall of the guiding vertical plate 32, a second arc-shaped groove 33 is formed on the rotating seat 31, the nut threadedly connected to the first screw 30 abuts against the surface of the notch of the second arc-shaped groove 33, one end of the first screw 30 away from the nut passes through the second arc-shaped groove 33 and is connected to the top of the slide bar 28. The first screw 30 is located at the top of the slide bar 28 away from one end of the connecting shaft 29. The outer diameter of the first screw 30 is smaller than the width of the second arc-shaped groove 33, and the diameter of the nut threadedly connected to the first screw 30 is larger than the width of the second arc-shaped groove 33.

[0091] In actual use, when specifically rotating and adjusting the profile guide 26 around the connecting shaft 29, the nut threadedly connected to the first screw 30 can be turned to make the rotating seat 31 and the slide bar 28 in an active state. Then, for the posture to be adjusted of the profile guide 26, the rotating seat 31 is rotated along the surface of the slide bar 28 to the corresponding position. At the same time, the guiding vertical plate 32 connected to the side wall of the rotating seat 31 is also rotated to the corresponding position. Then, turn the nut threadedly connected to the first screw 30 to abut against the surface of the notch of the second arc-shaped groove 33 to temporarily lock the entire rotating seat 31 and the guiding plate 32 in place, so as to complete the process of rotating and adjusting the profile guide 26 around the connecting shaft 29.

[0092] It should be noted that a gap is reserved between the bottom of the rotating seat 31 and the top of the cutting workbench 2, so that there will be no interference between the bottom of the rotating seat 31 and the top of the cutting workbench 2 when the rotating seat 31 rotates on the cutting workbench 2.

[0093] Please refer to Figure 1 , the profile to be cut 24 for clamping and cooperating with the profile guide 26 includes an L-shaped abutting baffle 34, a guide slide bar 35 and an adjusting bolt 36; wherein, the L-shaped abutting baffle 34 is used for clamping and cooperating with the guide vertical plate 32 in the profile guide 26 to clamp the profile to be cut; the adjusting bolt 36 is used to lock the L-shaped abutting baffle 34 in place on the guide slide bar 35; on the one hand, the guide slide bar 35 is used for slidingly adapting to the chute 46 at the top of the cutting workbench 2 to drive the L-shaped abutting baffle 34 locked on the guide slide bar 35 to move left or right horizontally, and on the other hand, the guide slide bar 35 is used for connecting to one end of the slide bar 28 in the guide moving member 25, so that when the slide bar 25 moves left or right horizontally on the top of the cutting workbench 2, the rotating seat 31 located on the top of the slide bar 28 will move synchronously with the L-shaped abutting baffle 34 towards the cutting blade 16 or away from the cutting blade 16 on the top of the cutting workbench 2. In this way, the profile to be cut clamped between the rotating seat 31 and the L-shaped abutting baffle 34 also moves synchronously towards the cutting blade 16 or away from the cutting blade 16, completing the process of feeding the clamped profile to the cutting head 16 for cutting and the process of taking the profile with the cut angle away from the cutting head 16.

[0094] Specifically, an accommodation space two 27 for placing the profile to be cut is defined between the L-shaped abutting baffle 34 and the guide vertical plate 32. The nut in the adjusting bolt 36 abuts against the outer wall of the orifice of the through hole 37 opened on the L-shaped abutting baffle 34. The bolt rod in the adjusting bolt 36 passes through the through hole 37 opened on the L-shaped abutting baffle 34 and is threadedly connected to the threaded adjusting hole 38 on the guide slide bar 35. A plurality of threaded adjusting holes 38 are arranged at intervals along the top of the guide slide bar 35. One end of the guide slide bar 35 away from the L-shaped abutting baffle 34 is connected to one end of the slide bar 28. The guide slide bar 35 is slidably connected to the chute 46 at the top of the cutting workbench 2.

[0095] In actual operation, when the L-shaped abutting baffle 34 and the guiding vertical plate 32 cooperate to clamp the profile to be cut, first, according to the cutting posture required for the profile to be cut, in accordance with the adjustment process of adjusting the placement posture of the guiding vertical plate 32 as described above, the guiding vertical plate 32 is adjusted to a position matching the required cutting posture of the profile to be cut. Then, the profile to be cut is placed against the outer wall of the guiding vertical plate 32. Next, the L-shaped abutting baffle 34 is moved towards the guiding vertical plate 32 to abut against the other side of the profile to be cut. Finally, the bolt rod in the adjusting bolt 36 passes through the through hole 37 opened on the L-shaped abutting baffle 34 and is threadedly connected to the corresponding threaded adjusting hole on the guiding slide bar 35, and the nut in the adjusting bolt 36 abuts against the surface of the orifice of the through hole 37 opened on the L-shaped abutting baffle 34, so as to temporarily lock the L-shaped abutting baffle 34 and the guiding slide bar 35, indirectly making the L-shaped abutting baffle 34 and the guiding vertical plate 32 clamp the profile to be cut more stably.

[0096] It should be noted that the top of the guiding slide bar 35 that is slidably engaged with the chute 46 protrudes slightly from the top slot of the chute 46, and the top of the slide bar 28 that is slidably engaged with the chute 31 protrudes slightly from the top slot of the chute 31.

[0097] Please refer to Figure 13 , for referring to the angle adjusted by the guiding vertical plate 32, a folding cutting device further includes an angle adjustment reference member II 39. The angle adjustment reference member II 39 includes a connecting block 40, an indicating needle II 41 and an angle marking arc bar II 42. Among them, the connecting block 40 is used to connect with the top of the slide bar 28; one end of the indicating needle II 41 is used to connect with the connecting block 40, and the other end is used to correspond to the angle parameter on the angle marking arc bar II 42 on the rotating seat 31; the angle marking arc bar II 42 is used to cooperate with the indicating needle II 41, so that during the rotation of the rotating seat 31 around the connecting shaft 29, the angle parameter corresponding to the indicating needle II 41 and the angle marking arc bar I 22 on the rotating seat 31 in place of rotation can be seen, and indirectly, the angle adjusted by the guiding vertical plate 32 can be known.

[0098] Specifically, the connecting block 40 is connected to one end of the slide bar 28 away from the guiding vertical plate 32. The top of the connecting block 40 is connected to the bottom of the indicating needle II 41. The indicating end of the indicating needle II 41 corresponds to the angle parameter engraved on the angle marking arc bar II 42. The angle marking arc bar II 42 is disposed around one side of the second arc groove 33 on the rotating seat 31.

[0099] In actual use, when adjusting the angle of the rotating seat 31 around the connecting shaft 29 to indirectly adjust the angle of the guiding vertical plate 32 connected to the rotating seat 31, during the process, for the angle to be adjusted of the guiding vertical plate 32, referring to the angle parameters on the angle marking arc strip two 42, pull the rotating seat 31 to rotate around the connecting shaft 29 until it stops at the position previously referred to by the indicating needle two 41. At the same time, the guiding vertical plate 32 connected to the rotating seat 31 also rotates to the required angle position and stops. Then, turn the nut threadedly connected to the first screw 30 to abut against the outer wall of the notch of the second arc groove 33, temporarily locking the entire rotated rotating seat 31 and guiding plate 32, further improving the accuracy of adjusting the angle of the guiding vertical plate.

[0100] It should be noted that a certain distance is reserved between the indicating needle two 41 and the angle marking arc strip two 42, that is, when the rotating seat 31 rotates, the indicating needle two 41 interferes with the angle marking arc strip two 42 on the rotating seat 31.

[0101] The above is the folding cutting device proposed by the present invention in the first aspect. The following is the usage method of the folding cutting device proposed by the present invention in the second aspect. Please refer to 1. A usage method of a folding cutting device includes the following steps:

[0104] S3. For the cutting angle required for the profile to be cut, adjust the angle-adjustable cutting member 3 provided on the cutting workbench 2 to the cutting angle of the profile to be cut by adjusting the adjustable member 5 on the side of the cutting workbench 2.

[0105] S4. After the angle-adjustable cutting member 3 is adjusted to match the cutting angle of the profile to be cut, place the profile to be cut on the top of the cutting workbench 2 in a lying and longitudinal posture.

[0106] S5. Drive the angle-adjustable cutting member 3 to operate, and push the profile to be cut in the direction of the cutting end of the angle-adjustable cutting member 3 pre-adjusted on the top of the cutting workbench 2.

Then, according to the cutting angle required for the profile to be cut, adjust the angle-adjustable cutting member 3 provided on the cutting workbench 2 to the cutting angle of the profile to be cut by adjusting the adjustable member 5 on the side of the cutting workbench 2. After the angle-adjustable cutting member 3 is adjusted to match the cutting angle of the profile to be cut, place the profile to be cut in a horizontal and longitudinal position on the top of the cutting workbench 2. Subsequently, drive the angle-adjustable cutting member 3 to operate, and push the profile to be cut towards the cutting end direction of the angle-adjustable cutting member 3 with a pre-adjusted angle on the top of the cutting workbench 2. The angle-adjustable cutting member 3 cuts the profile to be cut into the required profile. After all the profiles to be cut are cut, drive the angle-adjustable cutting member 3 to stop operating, remove the cut profile finished products and cutting waste from the cutting workbench 2, and then place the previously upright-standing folded cutting device in a horizontal lying position. Finally, fold each support leg 1 on the cutting workbench 2 of the horizontally lying folded cutting device to fit with the cutting workbench 2, and then place the folded cutting device with the support legs 1 stored properly at the maintenance appliance storage location to solve the problem that the existing cutting operation table with a cutting function is inconvenient to store.
