Description

Technical Field

[0001] This utility model relates to the field of cutting technology, and in particular to a folding cutting device. Background Technology

[0002] In the tobacco industry, a maintenance room is typically set up within the tobacco production workshop to repair malfunctioning tobacco equipment. The repair process utilizes various maintenance platforms, such as cutting tables with cutting functions. These cutting tables are specifically used to process twisted or deformed trusses in the faulty equipment. Specifically, when replacing a twisted or deformed truss, the repair worker first uses the cutting table to cut the intersection angles of the various profiles forming the truss, based on the specifications of the previously undistorted truss. Then, one end of the cut profile is joined to the other end of another cut profile, and a connecting sleeve and bolts are used to secure the joint. This process is repeated until the entire truss frame is fabricated. Finally, the twisted or deformed truss is removed from the faulty tobacco equipment, and the new truss is installed.

[0003] Although the above-mentioned cutting workbench with cutting function can complete the process of cutting profiles, the existing cutting workbench with cutting function still has the following defects in actual use: (1) Due to the large overall size of the cutting workbench with cutting function and the inconvenience of storage, coupled with the limited maintenance space in the maintenance room, the maintenance of tobacco equipment in the maintenance room with limited maintenance 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 of the existing cutting workbench with cutting function cannot be adjusted. When cutting the profile at a certain angle, the profile can only be tilted at a certain angle for cutting. Therefore, the processing method of the cutting workbench with cutting function is relatively simple, which reduces the practicality of the equipment.

[0004] Therefore, it is necessary to improve the overall structure of the cutting workbench in order to solve the problems of the existing cutting workbench with cutting function being inconvenient to store, hindering other maintenance activities, and having relatively limited processing methods.

[0021] In the work process, when cutting the profiles used in the truss of the faulty tobacco equipment in the maintenance room, the folding cutting device can be laid flat and placed horizontally. Then, each support leg that is pre-stored on the cutting worktable of the horizontally placed folding cutting device can be rotated to a position that is 90° with one of the walls of the cutting worktable.

[0022] After the four support legs have rotated into place, place the folding cutting device with the support legs in place in a standing position.

[0023] To determine the required cutting angle for the profile to be cut, the adjustable cutting component on the side of the cutting table is adjusted to match the required cutting angle of the profile to be cut.

On one hand, when not using the folding cutting device, the support leg of the folding cutting device can be folded up and stored in a corner of the maintenance room, saving space and allowing for other maintenance activities on tobacco equipment. On the other hand, when cutting profiles at the required angle, the angle of the adjustable-angle cutting component can be adjusted to cut the profile at the desired angle. Alternatively, the profile can be tilted at a certain angle and cut using the adjustable-angle cutting component without adjusting the cutting angle. This dual cutting method addresses the limitations of existing cutting workbenches with cutting functions, such as inconvenience in storage, hindering other maintenance activities, and the limited processing capabilities of existing cutting workbenches.

Detailed Implementation

[0048] like Figure 1-17 As shown, to make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0049] Example

[0050] The existing cutting workbench with cutting function can complete the process of cutting profiles, but the existing cutting workbench with cutting function still has the following defects in actual use: (1) Due to the large overall size of the cutting workbench with cutting function and the inconvenience of storage, coupled with the limited maintenance space in the maintenance room, the maintenance of tobacco equipment in the maintenance room with limited maintenance 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 of the existing cutting workbench with cutting function cannot be adjusted. When cutting the profile at a certain angle, the profile can only be tilted at a certain angle for cutting. Therefore, the processing method of the cutting workbench with cutting function is relatively simple, which reduces the practicality of the equipment.

[0051] Therefore, this application proposes a folding cutting device to solve the problems of existing cutting workbenches with cutting functions being inconvenient to store, hindering other maintenance activities, and having limited processing capabilities.

[0052] For details, please refer to Figure 1 and Figure 2 A folding cutting device includes a support leg 1, a cutting worktable 2, an angle-adjustable cutting component 3, and an adjustable component 5. One end of the support leg 1, which is away from the ground, is rotatably and adjustablely connected to the bottom of the cutting worktable 2. The cutting end of the angle-adjustable cutting component 3 passes through a through slot 4 opened at the top of the cutting worktable 2 and extends out. One end of the angle-adjustable cutting component 3 is rotatably and adjustablely connected to one of the inner side walls of the cutting worktable 2, and the other end of the angle-adjustable cutting component 3 is rotatably and adjustablely connected to the other inner side wall of the cutting worktable 2 through the adjustable component 5.

[0053] In practical applications, when cutting the profiles used in the truss of a malfunctioning tobacco equipment in a maintenance room, the folding cutting device, stored in a corner of the maintenance room, can be placed in a suitable position. The four support legs 1, pre-stored at the bottom of the cutting worktable 2, should be unfolded to support the entire cutting worktable 2 (supporting the entire cutting worktable 2 ensures the folding cutting device remains upright). Then, adjust the adjustable parts 5 on the side of the cutting worktable 2 according to the required cutting angle of the profiles used in the truss. Adjust the angle-adjustable cutting parts 3 on the cutting worktable 2 to the appropriate cutting angle. Push the profile to be cut towards the cutting end of the pre-adjusted angle-adjustable cutting parts 3 on the top of the cutting worktable 2. The rotating angle-adjustable cutting parts 3 will cut the profile into the required shape. Then, retract the angled profiles and scraps from the top of the cutting worktable 2. Finally, retract the cutting worktable 2. The top support leg 1 folds and fits snugly against the bottom of the cutting workbench 2. Finally, the folded cutting device with the support leg 1 folded up is placed in the corner of the maintenance room. In this way, on the one hand, when the folded cutting device is not in use, the support leg of the folded cutting device can be folded up and the folded cutting device with the support leg 1 folded up can be stored in the corner of the maintenance room, saving space in the maintenance room for other maintenance activities of tobacco equipment and machinery. On the other hand, when cutting profiles to the required cutting angle, the angle of the cutting end of the angle-adjustable cutting piece 3 can be adjusted to cut the profile at an angle. The profile can also be tilted at a certain angle and cut with the angle-adjustable cutting piece without adjusting the cutting angle. In this way, the two cutting methods make the processing methods no longer single, which solves the problems of existing cutting workbenches with cutting functions being inconvenient to store, hindering other maintenance activities, and having relatively limited processing methods.

[0054] Please see Figure 3 To ensure that the support leg 1 can stably support the cutting worktable 2 when it is unfolded, the support leg 1 includes an L-shaped adjustable base 44, a support leg 6, and a locking bolt 7. The L-shaped adjustable base 44 and the locking bolt 7 work together to temporarily lock the support leg 1 when it is changed from the folded state to the unfolded state. This ensures that the unfolded support leg 1 stably supports the cutting worktable and allows for a rotatable and adjustable connection between the end of the support leg 1 away from the ground and the bottom of the cutting worktable 2. The support leg is used to support the cutting worktable 2, which facilitates the subsequent cutting of profiles on the cutting worktable 2.

[0055] Specifically, two L-shaped adjustable seats 44 are symmetrically arranged at the bottom of the cutting worktable 2. The space 8 for the support leg 6 to rotate is defined between the two L-shaped adjustable seats 44. Part of the support leg 6 is located in the space 8 for the support leg 6 to rotate and is rotatably connected to the bottom of the cutting worktable 2. The bolt rod of the locking bolt 7 passes through the arc-shaped adjustment groove 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 leg 6. The nut in the locking bolt 7 abuts against the surface wall of the arc-shaped adjustment groove 9 opened on the side wall of the L-shaped adjustable seat 44. The arc-shaped adjustment groove 9 is an arc-shaped adjustment groove. The width of the arc-shaped adjustment groove is greater than the outer diameter of the bolt rod in the locking bolt 7, and the width of the arc-shaped adjustment groove is less than the diameter of the nut in the locking bolt 7.

[0056] In practical applications, after the pre-installed support leg 6 at the bottom of the cutting table 2 is extended to a position at a 90° angle to the bottom of the cutting table 2, the bolt rod of the locking bolt 7 can be passed through the arc-shaped adjustment groove 9 on the side wall of the L-shaped adjustable seat 44 and threadedly connected to the threaded hole on the side wall of the support leg 6. Then, the locking bolt 7 is tightened so that the nut in the locking bolt 7 is in tight contact with the surface of the arc-shaped adjustment groove 9 on the side wall of the L-shaped adjustable seat 44, thereby locking the support leg 6 at a 90° angle to the bottom of the cutting table 2. This prevents the support leg 6 from rotating around the bottom of the cutting table 2 at will, which would affect the subsequent cutting of the profile on the cutting table and indirectly improve the stability of the support leg 6 for the cutting table 2.

[0057] When folding the support leg 6, which is at a 90° angle to the bottom of the cutting table 2, the locking bolt 7 at the arc-shaped adjustment groove 9 on the side wall of the L-shaped adjustable seat 44 can be turned so that the nut in the locking bolt 7 does not abut against the surface of the arc-shaped adjustment groove 9 on the side wall of the L-shaped adjustable seat 44. Then, pull the support leg 6 to fold it inwards towards the cutting table 2. When the support leg 6 is folded to the bottom of the cutting table 2, turn the locking bolt 7 again so that the nut in the locking bolt 7 abuts against the surface of the arc-shaped adjustment groove 9 on the side wall of the L-shaped adjustable seat 44. This locks the position of the support leg 6 at the bottom of the cutting table 2 and prevents the support leg 6 from rotating around the bottom of the cutting table 2 during the handling of the folding cutting device, which would make it inconvenient to move the folding cutting device.

[0058] It should be noted that some of the legs 6 are located in the space 8 for the legs 6 to rotate and are rotatably connected to the bottom of the cutting table 2. That is, the legs 6 located in the space 8 are rotatably connected to the L-shaped adjustable seats 44. This means that when the legs 6 rotate from the space 8 for the legs 6 to rotate between the two L-shaped adjustable seats 44, they are not interfered with by the two L-shaped adjustable seats 44.

[0059] It should be noted that the nut in the locking bolt 7 abuts against the surface of the arc-shaped adjustment groove 9 on the side wall of the L-shaped adjustable seat 44. That is, when the locking bolt 7 is used to lock the extended support leg, the nut in the locking bolt 7 abuts against the surface of the arc-shaped adjustment groove 9 on the side wall of the L-shaped adjustable seat 44; when the locking bolt 7 is not used to lock the extended support leg, the nut in the locking bolt 7 abuts against the surface of the arc-shaped adjustment groove 9 on the side wall of the L-shaped adjustable seat 44.

[0060] It should be noted that the cutting workbench 2 is a rectangular structural frame with one side wall closed, three side walls open, and a closed top.

[0061] Please see Figure 3 To facilitate the use of the folding cutting device for cutting profiles by maintenance workers of different heights, the support leg 6 for adjusting the height of the folding cutting device includes a support column 10, an adjusting sleeve 11, a locking handle 43 with a threaded rod, and a base 12; wherein, the support column 10 is used to rotatably connect with the bottom of the cutting workbench 2; the adjusting sleeve 11 is used to slide to the other end of the support column 10 to adjust the overall height of the folding cutting device; the locking handle 43 with a threaded rod is used to temporarily lock the support column 10 when it moves up or down into position inside the adjusting sleeve 11.

[0062] Specifically, a threaded hole is opened on the side wall of the support column 10 near the bottom of the cutting worktable 2. One end of the support column 10 away from the ground passes through the space 8 defined between the two L-shaped adjustable seats 44 and is rotatably connected to the bottom of the cutting worktable 2. That is, an internal threaded hole is opened on the side wall of the adjusting sleeve 11. One end of the threaded rod in the locking handle 43 with the threaded rod is threadedly connected to the internal threaded hole on the outer wall of the adjusting sleeve 11 and extends into the adjusting sleeve 11 to abut against the side wall of the support column 10 inside the adjusting sleeve 11. The closed end of the adjusting sleeve 11 away from the support column 10 is connected to the top of the base 12.

[0063] In practical applications, before cutting profiles using a standing folding cutting device (a standing folding cutting device: the legs in the folding cutting device are unfolded and support the folding cutting device), the threaded locking handle 43 can be turned so that one end of the threaded rod in the locking handle 43 does not abut against the support column 10 inside the adjusting sleeve 11. Then, move it up or down along the inside of the adjusting sleeve 11 to a suitable position to move the overall height of the folding cutting device to a height suitable for maintenance personnel to operate. Then, turn the threaded locking handle 43 again so that one end of the threaded rod in the locking handle 43 abuts against the support column 10 that has been moved into place inside the adjusting sleeve 11 and locks it. In this way, it is convenient for maintenance workers of different heights to operate, indirectly improving the practicality of the folding cutting device.

[0064] Please see Figure 4The angle-adjustable cutting component 3 for cutting profiles includes an angle grinder 13, a connecting seat 14, and a rotating arm 15. The angle grinder 13 is used to cut the profiles. The connecting seat 14 is used to install and fix the angle grinder 13. The rotating arm 15 is used to drive the connecting seat 14 to rotate, which indirectly causes the angle grinder 13 on the connecting seat 14 to rotate synchronously, so as to realize that the angle of the angle-adjustable cutting component 3 is adjustable.

[0065] Specifically, the angle grinder 13 is located inside the cutting table 2. The cutting blade 16 of the angle grinder 13 passes through and extends out of the through slot 4 opened on the cutting table 2. The fixed end of the angle grinder 13 is connected to the side wall of the connecting seat 14 located inside the cutting table 2. The two ends of the connecting seat 14 are respectively connected to one end of the rotating arm 15. One end of the rotating arm 15 is rotatably connected to one inner wall of the cutting table 2, and the other end of the rotating arm 15 is rotatably and adjustablely connected to the other side wall of the cutting table 2 through the adjustable part 5.

[0066] In practical applications, when using the angle-adjustable cutting component 3 to cut profiles, first adjust the adjustable component 5 so that the rotating arm 15 connected to one end of the adjustable component 5 and one of the inner walls of the cutting table 2 are in an active state. Then, adjust the adjustable component 5 according to the angle to be cut of the profile so that the rotating arm 15 connected to one end of the adjustable component 5 rotates to the corresponding position, indirectly driving the connecting seat 14 connected through the rotating arm 15 to rotate to the corresponding position as well. In this way, while the connecting seat 14 rotates to the corresponding position, the cutting blade 16 in the angle grinder 13 also shifts to a certain position through the groove 4, that is, the cutting angle of the angle grinder 13 is adjusted. Then, the profile to be cut is laid flat longitudinally and pushed towards the cutting blade 16 with the adjusted cutting angle. The rotating cutting blade then cuts the profile to the required cutting angle.

[0067] It should be noted that the angle grinder 13 is existing technology. This application replaces the grinding disc on the angle grinder 13 with a cutting blade 16. As for other components of the angle grinder 13, no improvements or designs have been made to them, so their structure will not be described in detail.

[0068] The width of the slots between the through slots 4 is sufficient to allow the cutting blade 16 to deflect during the angle adjustment process. That is, the deflected cutting blade 16 will not interfere with the inner wall of the through slot 4. The cutting blade 16 is set as a circular blade with a serrated outer edge.

[0069] It should be noted that connector 14 and... Figure 7 A certain clearance is reserved between the inner wall of the cutting table 1 near reference numeral 2 in the attached figure to prevent the rotating connecting seat 14 from interfering with the inner wall of the cutting table 1 during rotation. Figure 7 Interference occurs on the inner wall of the cutting table 1 near the reference numeral 2 in the attached figure.

[0070] Please see Figure 5 , Figure 6 , Figure 8 , Figure 9 and Figure 10 The adjustable component 5 for adjusting the cutting angle of the cutting blade 16 includes an adjusting screw 17 and an adjusting nut 45. The adjusting screw 17 is connected to one of the rotating arms 15 so that moving the adjusting screw 17 drives the rotating arm 15 to rotate, which in turn drives the connecting seat 14 connected to the rotating arm 15 to rotate, so that the cutting blade 16 in the angle grinder 13 on the connecting seat 14 is offset in the through groove 4. The adjusting nut 45 is used to lock the adjusting screw 17 in place so that the cutting blade 16 with the adjusted cutting angle is temporarily held in the adjusted angle position.

[0071] Specifically, the adjusting screw 17 passes through the first arc-shaped groove 18 opened on one side wall of the cutting table 2 and is connected to the connecting post connected to the side wall of one of the rotating arms 15. The end of the adjusting screw 17 away from the side wall of one of the rotating arms 15 is threaded to the adjusting nut 45. The adjusting nut 45 abuts against the outer side wall of the cutting table 2 where the first arc-shaped groove 18 is opened. The diameter of the adjusting nut 45 is greater than the width of the first arc-shaped groove 18, and the width of the first arc-shaped groove 18 is greater than the outer diameter of the adjusting screw 17.

[0072] In practical application, when adjusting the cutting angle of the cutting blade 16 using the adjustable part 5, the adjusting nut 45, which is threadedly connected to the adjusting screw 17, can be turned to make the rotating arm 15, which is connected to one end of the adjusting screw 17 via a connecting post, movable relative to one inner wall of the cutting table 2. Then, for the angle to be cut on the profile, the adjusting screw 17, which is connected to the connecting post on the side wall of one of the rotating arms 15, is pulled along the first arc groove 18 to the corresponding position. At the same time, the connecting seat 14, which is connected to one of the rotating arms 15, also moves to the corresponding position, indirectly... The cutting blade 16 in the angle grinder on the connecting seat 14 is offset in the through groove 4. After the cutting blade 16 is offset to the corresponding position in the through groove 4, the adjusting nut 45 threaded on the adjusting screw 17 is turned to abut against the side wall of the cutting table 2 with the first arc groove 18. This makes the rotating arm 15 connected to one end of the adjusting screw 17 through the connecting column and one of the inner walls of the cutting table 2 temporarily locked, indirectly locking the angle-adjusted cutting blade 16 so that the profile cutting operation can be carried out with the angle-adjusted cutting blade 16.

[0073] Please see Figure 8 and Figure 9To provide a reference for the angle adjusted by the cutting blade 16, a folding cutting device further includes an angle adjustment reference component 19. The angle adjustment reference component 19 includes a sliding post 20, an indicator needle 21, and an angle marking arc strip 22. The sliding post 20 is connected to the side wall of the rotating arm 15 connected to the adjusting screw 17, so that when the adjusting screw 17 moves with the rotating arm 15 to adjust the cutting angle of the cutting blade 16, the sliding post 20 connected to one of the rotating arms 15 also moves. The indicator needle 21 is connected to the sliding post 20, so that when the sliding post 20 moves with the rotating arm 15, the indicator needle 21 also moves. The angle marking arc strip 22 is used in conjunction with the indicator needle 21, so that when the indicator needle 21 moves with the sliding post 20 to a position corresponding to a certain position of the angle marking arc strip 22, the cutting angle adjusted by the cutting blade 16 can be indirectly known through the angle parameters on the angle marking arc strip 22.

[0074] Specifically, the sliding column 20 is slidably connected to the first arc-shaped groove 18 opened on the side wall of the cutting worktable 2. One end of the sliding column 20 is connected to the side wall of the rotating arm 15 connected to the adjusting screw 17. The other end of the sliding column 20 extends out from the first arc-shaped groove 18 opened on the side wall of the cutting worktable 2 and is connected to the indicator needle 21. The other end of the indicator needle 21 corresponds to the angle parameter engraved on the angle marking arc strip 22. The angle marking arc strip 22 surrounds the side of the first arc-shaped groove 18 opened on the side wall of the cutting worktable 2.

[0075] In practical applications, when the adjusting screw 17 is pulled to rotate the connecting seat 14 connected to one of the rotating arms 15, indirectly adjusting the angle of the cutting blade 16 in the angle grinder 13 on the connecting seat 14, the angle to be adjusted for the cutting blade 16 can be determined by referring to the angle parameter on the angle marking arc strip 22. The adjusting screw 17 connected to one of the rotating arms 15 is pulled along the first arc groove 18. At the same time, the sliding column 20 connected to the side wall of the rotating arm 15 connected to the adjusting screw 17 also moves along the first arc groove 18. When the indicator needle 21 connected to the sliding column 20 moves to a point where the angle parameter on the angle marking arc strip 22 is close to the angle to be adjusted for the cutting blade 16, the adjusting nut threaded to the adjusting screw 17 is turned to abut against the side wall of the cutting table 2 with the first arc groove 18. This temporarily locks the rotating arm 15 connected to one end of the adjusting screw 17 through the connecting column to one of the inner walls of the cutting table 2, further improving the accuracy of adjusting the cutting angle of the cutting blade 16.

[0076] It should be noted that there is a distance between the indicator needle 21 and the angle marking arc strip 22, that is, when the indicator needle 21 rotates, it will not interfere with the angle marking arc strip 22.

[0077] Please see Figure 11To facilitate clamping of the profile to be cut and ensure stable cutting, a folding cutting device further includes a profile guide 23 and a profile stop 24. The profile guide 23 includes a moving part 25 and a profile guide 26. The profile guide 26 is used to adjust the placement angle or orientation of the profile to be cut. The profile guide 26 and the profile stop 24 clamp together to clamp the profile to be cut, which is placed between the profile guide 26 and the profile stop 24 and has been adjusted in orientation. The moving part 25 drives the profile guide 26, the profile stop 24, and the profile to be cut, which has been adjusted in orientation and is clamped between the profile guide 26 and the profile stop 24, to move horizontally on the top of the cutting table 2 toward the cutting blade 16 or away from the cutting blade 16.

[0078] Specifically, the profile guide 23 to be cut includes a movable part 25 and a profile guide 26. The movable part 25 is located on the cutting table 2 near the cutting blade 16. The movable part 25 moves along the cutting table 2. The profile guide 26 is rotatably and adjustablely connected to the movable part 25. The profile stop 24 to be cut is located on the moving path of the profile guide 23 to be cut. The profile stop 24 to be cut is adjustablely connected to the profile guide 26. The profile guide 26 and the profile stop 24 to be cut define a space 27 for placing the profile to be cut. The profile stop 24 to be cut moves along the cutting table 2.

[0079] In practical applications, when the profile guide 23 and the profile stop 24 on the standing folding cutting device clamp the profile to be cut so that the cutting blade 16 can cut the profile to be cut at the required angle, there are two processing methods for cutting the profile. The first processing method is to adjust the angle of the cutting blade without adjusting the orientation or angle of the profile to be cut between the profile guide 26 and the profile stop 24. The second processing method is to adjust the orientation or angle of the profile to be cut between the profile guide 26 and the profile stop 24 without adjusting the angle of the cutting blade.

[0080] Specifically, when cutting the profile to be cut using the first processing method (the first processing method adjusts the angle of the cutting blade, but does not adjust the orientation or angle of the profile to be cut held between the profile guide 26 and the profile stop 24), first adjust the cutting angle of the cutting blade 16 according to the previous steps for adjusting the cutting angle of the cutting blade 16, then adjust the profile guide 26 in the profile guide 23 to be parallel to the profile stop 24 to be cut, then place the profile to be cut in a horizontal longitudinal position between the profile guide 26 and the profile stop 24 to be cut, and then adjust the profile stop 24 to be cut so that the profile stop 24 to be cut moves toward the profile guide 26, thus cutting the profile that was previously placed between the profile guide 26 and the profile stop 24. The profile to be cut is clamped between the profile guide 26 and the profile stop 24. Then, the moving part 25 is pushed to move towards the cutting blade 16 with the pre-adjusted cutting angle. The profile to be cut between the profile guide 26 and the profile stop 24 is cut into the required angle by the operating cutting blade 16. Then, the moving part 25 is pushed to move away from the cutting blade 16 to one side, and the profile stop 24 is adjusted to move away from the profile guide 26. Finally, the profile to be cut with the pre-cut angle between the profile guide 26 and the profile stop 24 is taken out to complete the profile cutting process using the first processing method.

[0081] When cutting the profile using the second processing method (second processing method: without adjusting the angle of the cutting blade 16, but adjusting the orientation or angle of the profile to be cut between the profile guide 26 and the profile stop 24 to be cut), first keep the cutting blade 16 parallel to the edge of the cutting table, that is, do not adjust the angle of the cutting blade 16. Then adjust the profile guide 26 in the profile guide 23 so that it is not parallel to the profile stop 24 to be cut. Then place the profile to be cut against the profile guide 26 in its current position (placed against the profile guide 26 in its current position: the profile to be cut is placed at a certain angle to the horizontal direction). Then adjust the profile stop 24 to face the profile. The guide member 26 moves in a direction to clamp the profile to be cut, which is pre-placed between the profile guide member 26 and the profile to be cut stop member 24. Then, the moving member 25 is pushed to move towards the cutting blade 16, which has not been adjusted for cutting angle. The profile to be cut, which is clamped between the profile guide member 26 and the profile to be cut stop member 24, is then cut into the required angle by the operating cutting blade 16. Next, the moving member 25 is pushed to move away from the cutting blade 16 to one side, and the profile to be cut stop member 24 is adjusted so that it moves away from the profile guide member 26. Finally, the profile to be cut, which has been cut at the correct angle between the profile guide member 26 and the profile to be cut stop member 24, is taken out to complete the process of cutting the profile using the second processing method.

[0082] Thus, in the process of cutting profiles to the required angle using this folding cutting device, not only can the first processing method mentioned above be used to cut the profiles, but the second processing method mentioned above can also be used to cut the profiles, making the processing methods no longer limited, thereby solving the problem that the processing methods of existing cutting operation tables with cutting functions are relatively limited.

[0083] Please see Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17 The guide moving component 25, which is used to drive the profile guide 26 to move horizontally along the cutting worktable 2 or is rotatably adjustable with the profile guide 26, includes a slide bar 28, a connecting shaft 29, and a first screw 30. The slide bar 28 is slidably connected to the slide groove 46 on the top of the cutting worktable 2 to drive the slide bar 28 and other components set on the top of the slide bar 28 to move horizontally along the cutting worktable 1. The profile guide 26 is rotatably connected to the connecting shaft 29, which is used to make the profile guide 26 rotate circumferentially. The first screw 30 cooperates with the nut to temporarily lock the profile guide 26 when it is rotated into place.

[0084] Specifically, the slide bar 28 is slidably connected to the slide groove 46 opened on the top of the cutting worktable 2, the bottom of the connecting shaft 29 is connected to the top of the slide bar 28, the profile guide 26 is rotatably connected to the connecting shaft 29, and the profile guide 26 is rotatably and adjustablely connected to the top of the slide bar 28 through the first screw 30 and the nut threadedly connected to the first screw 30.

[0085] In practical applications, when the guide moving part 25 moves the profile guide part 26 on the top of the cutting table 2 toward or away from the cutting blade 16, the slide bar 28 can be pushed to move horizontally to the right or left along the top slide groove 46 of the cutting table 2. The profile guide part 26, which is 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 along the top slide groove 46 of the cutting table 2, making the profile guide part 26 move more smoothly.

[0086] When adjusting the placement posture of the profile guide 26 so that the profile to be cut can be placed in the required posture, the nut threaded to the first screw 30 can be turned to make the slide bar 28 and the profile guide 26 in an active state. Then, according to the required cutting posture of the profile to be cut (the required placement posture of the profile to be cut: the orientation of the profile to be cut or the orientation of the profile to be cut that is inclined to the horizontal direction), the profile guide 26 is rotated to the corresponding position along the connecting shaft 29. Then, the nut threaded to the first screw 30 is turned to lock the profile guide 26 and the slide bar 28. Finally, the profile to be cut is placed against the side wall of the profile guide 26, which has been adjusted to the desired cutting posture, to help place the profile to be cut in the required cutting posture.

[0087] Please read Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17 The profile guide 26, which is rotatably and adjustablely connected to the connecting shaft 29, includes a rotating seat 31 and a guide plate 32. The rotating seat 31 is rotatably connected to the connecting shaft 29 at the top of the slide bar 28. The guide plate 32 is connected to the rotating seat 31 so that the guide plate 32 is synchronously rotated to the corresponding position under the rotation of the rotating seat 31.

[0088] 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 guide plate 32, and a second arc-shaped groove 33 is provided on the rotating seat 31. The nut that is threadedly connected to the first screw 30 abuts against the surface wall of the groove opening 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 at the end away from the connecting shaft 29. The outer diameter of the first screw 30 is smaller than the groove width of the second arc-shaped groove 33, and the diameter of the nut that is threadedly connected to the first screw 30 is larger than the groove width of the second arc-shaped groove 33.

[0089] In practical applications, when the profile guide 26 is rotated and adjusted around the connecting shaft 29, the nut threaded to the first screw 30 can be turned to make the rotating seat 31 and the slide bar 28 in an active state. Then, according to the posture to be adjusted of the profile guide 26, the rotating seat 31 is rotated to the corresponding position along the surface of the slide bar 28. At the same time, the guide plate 32 connected to the side wall of the rotating seat 31 is also rotated to the corresponding position. Then, the nut threaded to the first screw 30 is turned to abut against the surface wall of the second arc groove 33, temporarily locking the rotating seat 31 and the guide plate 32 in place, so as to complete the process of rotating and adjusting the profile guide 26 around the connecting shaft 29.

[0090] It should be noted that a gap is reserved between the bottom of the rotating seat 31 and the top of the cutting table 2, so that when the rotating seat 31 rotates on the cutting table 2, there will be no interference between the bottom of the rotating seat 31 and the top of the cutting table 2.

[0091] Please see Figure 1 The profile-to-be-cutting abutment 24, used for clamping and engaging with the profile guide 26, includes an L-shaped abutment baffle 34, a guide slide 35, and an adjusting bolt 36. The L-shaped abutment baffle 34 is used in conjunction with the guide plate 32 in the profile guide 26 to clamp the profile to be cut. The adjusting bolt 36 is used to lock the adjusted L-shaped abutment baffle 34 onto the guide slide 35. The guide slide 35 is used, on one hand, to slide and adapt to the groove 46 on the top of the cutting worktable 2, so as to drive the L-shaped abutment baffle 34 locked on the guide slide 35 to move horizontally to the left or right. On the other hand, the guide slide 35 is used to... One end of the slide bar 28 in the guide moving part 25 is connected so that when the slide bar 25 moves to the left or right in the horizontal direction at the top of the cutting table 2, the rotating seat 31 located at the top of the slide bar 28 will move synchronously with the L-shaped abutment baffle 34 at the top of the cutting table 2 in the direction closer to or away from the cutting blade 16. In this way, the profile to be cut, which is clamped between the rotating seat 31 and the L-shaped abutment baffle 34, also moves synchronously in the direction closer to or away from the cutting blade 16, thus completing the process of sending 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.

[0092] Specifically, the L-shaped abutment baffle 34 and the guide plate 32 define a space 27 for placing the profile to be cut. The nut in the adjusting bolt 36 abuts against the surface of the through hole 37 on the L-shaped abutment baffle 34. The bolt rod in the adjusting bolt 36 passes through the through hole 37 on the L-shaped abutment baffle 34 and is threadedly connected to the threaded adjusting hole 38 on the guide slide 35. Multiple threaded adjusting holes 38 are spaced apart along the top of the guide slide 35. One end of the guide slide 35 away from the L-shaped abutment baffle 34 is connected to one end of the slide 28. The guide slide 35 is slidably connected to the slide groove 46 on the top of the cutting worktable 2.

[0093] In practical applications, when the L-shaped abutment baffle 34 and the guide plate 32 work together to clamp the profile to be cut, first, according to the required cutting posture of the profile to be cut, adjust the guide plate 32 to a position that matches the required cutting posture of the profile to be cut, following the previous adjustment process of adjusting the placement posture of the guide plate 32. Then, place the profile to be cut against the outer wall of the guide plate 32. Then, move the L-shaped abutment baffle 34 towards the guide plate 32 to abut against the other side of the profile to be cut. Finally, use the bolt rod of the adjusting bolt 36 to pass through the through hole 37 opened on the L-shaped abutment baffle 34 and thread it to connect with the corresponding threaded adjustment hole on the guide slide 35. Make the nut in the adjusting bolt 36 abut against the surface wall of the through hole 37 opened on the L-shaped abutment baffle 34 to temporarily lock the L-shaped abutment baffle 34 and the guide slide 35, thereby indirectly making the L-shaped abutment baffle 34 and the guide plate 32 clamp the profile to be cut more stably.

[0094] It should be noted that the top of the guide rail 35, which slides in conjunction with the slide groove 46, protrudes slightly from the top opening of the slide groove 46, and the top of the rail 28, which slides in conjunction with the slide groove 31, protrudes slightly from the top opening of the slide groove 31.

[0095] Please see Figure 13 To provide a reference for the angle adjusted by the guide plate 32, a folding cutting device further includes an angle adjustment reference component 39. The angle adjustment reference component 39 includes a connecting block 40, an indicator needle 41, and an angle marking arc strip 42. The connecting block 40 is used to connect to the top of the slide bar 28. One end of the indicator needle 41 is used to connect to the connecting block 40, and the other end is used to correspond to the angle parameter on the angle marking arc strip 42 on the rotating seat 31. The angle marking arc strip 42 is used in conjunction with the indicator needle 41 so that, during the rotation of the rotating seat 31 around the connecting shaft 29, the angle adjusted by the guide plate 32 can be indirectly determined by observing the angle parameter corresponding to the indicator needle 41 and the angle marking arc strip 22 on the rotating seat 31 when it is in position.

[0096] Specifically, the connecting block 40 is connected to one end of the slide bar 28 away from the guide plate 32, the top of the connecting block 40 is connected to the bottom of the indicator needle 41, the indicating end of the indicator needle 41 corresponds to the angle parameter engraved on the angle marking arc strip 42, and the angle marking arc strip 42 surrounds one side of the second arc groove 33 on the rotating seat 31.

[0097] In practical applications, when adjusting the angle of the rotating seat 31 around the connecting shaft 29 to indirectly adjust the angle of the guide plate 32 connected to the rotating seat 31, the angle to be adjusted for the guide plate 32 can be determined by referring to the angle parameters on the angle marking arc strip 42. The rotating seat 31 is pulled around the connecting shaft 29 and rotated to the position previously referenced by the indicator needle 41. At the same time, the guide plate 32 connected to the rotating seat 31 also rotates to the required angle position and stops. Then, the nut threaded to the first screw 30 is turned to abut against the surface wall of the second arc groove 33, temporarily locking the rotating seat 31 and guide plate 32 in place, further improving the accuracy of adjusting the angle of the guide plate.

[0098] It should be noted that a certain distance is reserved between the second indicator needle 41 and the second angle marking arc strip 42, that is, when the rotating seat 31 rotates, the second indicator needle 41 interferes with the second angle marking arc strip 42 on the rotating seat 31.

[0099] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
