DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0021] like Figures 1 to 10 As shown, a local trimming device for electronic cigarette shell mold forming includes: a workbench 1, an electronic cigarette tube 3 and a cutting knife 7; also includes: a placing rotating part, which is arranged on the workbench 1; a clamping part 2, which is provided with four groups, and the four groups of clamping parts 2 are equidistantly arranged on the placing rotating part; so as to achieve internal and external clamping of the electronic cigarette tube 3; a cutting moving part 4, which is connected to the workbench 1 through a support member to control the rotation and up and down movement of the cutting knife 7; a cutting limiting part, which is connected to the cutting moving part 4 to limit the rotation trajectory of the cutting knife 7 to be the same as the specified elliptical trajectory; a cutting adjusting part, which is connected to the cutting limiting part and to the cutting knife 7 to accurately adjust the position of the cutting knife 7.

[0022] In the embodiment of the present invention, a clamping portion 2 is provided on the placement and rotation portion, so that multiple groups of clamping portions 2 are contacted with the cutting knife 7 in turn for cutting, so that multiple workpieces to be processed can form a cutting process and be cut in turn; at the same time, a cutting limit portion is provided to limit the moving path of the cutting knife 7 to be the same as the cutting path of workpieces to be processed of different shapes, so that the surfaces of workpieces to be processed of different shapes can be cut and scraped; a cutting adjustment member is provided to change the direction of the cutting knife 7, and when cutting the electronic cigarette tube 3, it cooperates with the clamping portion 2 so that both the inner wall and the outer surface of the electronic cigarette tube 3 can be cut to remove excess material, burrs, flash and other problems on the electronic cigarette tube 3.

[0023] like Figure 3 As shown, the placement and rotation part includes: a rotation groove 105, which is opened on the workbench 1; a rotation disk 104, which rotates in the rotation groove 105; and a first motor 106, which is arranged on the workbench 1, and the output end is connected to the rotation disk 104.

[0024] In the embodiment of the present invention, the rotating disk 104 is driven to rotate by starting the first motor 106. Since the clamping member is arranged on the rotating disk 104, the four groups of rotating disks 104 are driven to sequentially pass through the position of the cutting knife 7 for cutting; thereby, a group of clamping parts 2 before cutting performs a loading operation, and a group of clamping parts 2 after cutting performs a unloading operation, thereby realizing a complete process flow of cutting the electronic cigarette tube 3.

[0025] like Figures 4 to 5As shown, the clamping portion 2 includes: a placement plate 201, which is arranged on the rotating plate 104; a limiting groove 202, which is opened on the placement plate 201; a clamping member, which is arranged in the limiting groove 202 to clamp the electronic cigarette tube 3; a limiting member, which is arranged on the placement plate 201 to improve the placement efficiency of the electronic cigarette tube 3; a cleaning groove 209, which is opened on the placement plate 201 and is connected to the limiting groove 202 to facilitate cleaning of processing debris in the limiting groove 202.

[0026] like Figures 4 to 5 As shown, the clamping member includes: a second micro motor 203, which is arranged on the placement plate 201; a bidirectional screw 204, one end of which is connected to one end of the limiting groove 202 away from the second micro motor 203, and the other end is connected to the output end of the second micro motor 203; a threaded sleeve 205, which is provided in two groups, and the two groups of threaded sleeves 205 are symmetrically sleeved on the bidirectional screw 204 and threadedly connected to the bidirectional screw 204; a bidirectional clamping block 206, which is provided in two groups, and the two groups of bidirectional clamping blocks 206 are provided on the corresponding two groups of threaded sleeves 205.

[0027] like Figures 4 to 5 As shown, the limiting member includes: a first limiting rod 207 disposed at the center of the placement plate 201; and placement grooves 208 opened at both ends of the first limiting rod 207 to cooperate with the bidirectional clamping block 206.

[0028] In the embodiment of the present invention, before cutting the electronic cigarette tube 3, the electronic cigarette tube 3 is first clamped internally, so as to facilitate cutting the outer side of the electronic cigarette tube 3; when clamping, the electronic cigarette tube 3 is sleeved on the first limiting rod 207, so that the electronic cigarette tube 3 is placed on the placement plate 201, and then the second micro motor 203 is started, thereby driving the bidirectional screw 204 to rotate, and the rotation of the bidirectional screw 204 drives the two threaded sleeves 205 to move away from each other, thereby driving the two bidirectional clamping blocks 206 to move away from each other, until the two bidirectional clamping blocks 206 are both against the inner wall of the electronic cigarette tube 3 to clamp the electronic cigarette tube 3, and at this time, the rotation of the second micro motor 203 is stopped, thereby completing the internal clamping of the electronic cigarette tube 3.

[0029] Among them, before the electronic cigarette tube 3 is mounted on the first limiting rod 207, since the electronic cigarette tube 3 is elliptical, in order to avoid the two sides corresponding to the secondary axis being difficult to be mounted within the two bidirectional clamping blocks, the bidirectional clamping blocks are placed in the placement groove 208 on the first limiting rod 207, so that the two bidirectional clamping blocks are combined with the first limiting rod 207, thereby facilitating the mounting of the electronic cigarette tube 3.

[0030] When the two-way screw 204 is driven to rotate by the second micro motor 203 so that the two two-way clamping blocks move outward to clamp the elliptical electronic cigarette tube 3, if the two-way clamping blocks do not touch the elliptical sleeve, i.e., the two sides of the electronic cigarette tube 3 corresponding to the main axis, i.e., the two farthest ends of the elliptical sleeve, the elliptical sleeve will be driven to rotate under the action of the extrusion force until the two two-way clamping blocks are squeezed and fixed at the farthest ends on the inner wall of the elliptical sleeve. At this time, the clamping position of the elliptical sleeve is fixed in a fixed direction. Therefore, when clamping inside, the electronic cigarette tube 3 only needs to be arbitrarily mounted on the first limit rod 207 to achieve clamping and fixing of the electronic cigarette tube 3 in a fixed direction.

[0031] At the same time, when the electronic cigarette tube 3 is clamped externally, the two bidirectional clamping blocks need to be moved to the two ends of the placement plate 201, and then the staff will place the two sides corresponding to the main axis of the electronic cigarette tube 3 on the placement plate 201 corresponding to the two bidirectional clamping blocks, and then start the second micro motor 203 to drive the bidirectional screw 204 to rotate. The rotation of the bidirectional screw 204 drives the two threaded sleeves 205 to approach each other, thereby driving the two bidirectional clamping blocks 206 to approach each other, and finally clamping at the two ends farthest from the outer surface of the electronic cigarette tube 3 to perform the internal cutting operation.

[0032] Among them, the two-way clamping block is set in a "crescent shape", that is, the side of the two-way clamping block facing outward is set as a convex arc block, so as to facilitate the clamping with the arc-shaped inner wall of the electronic cigarette tube 3, making the internal clamping more stable; and the side of the two-way clamping block facing outward is set as a concave arc block, so as to facilitate the clamping with the arc-shaped outer surface of the electronic cigarette tube 3, making the external clamping more stable.

[0033] like Figure 1 to Figure 2 As shown, the support member includes: a support side plate 102, which is arranged on one side of the top of the workbench 1; a support top plate 103, one end of which is connected to the top of the support side plate 102; and a support rod 101, which is arranged at the bottom of the workbench 1.

[0034] In the embodiment of the present invention, a support rod 101 is provided to support the workbench 1 to ensure the stability of the workbench 1, and a supporting side plate 102 and a supporting top plate are provided to stably support the cutting moving part 4, the cutting limiting part and the cutting adjusting part.

[0035] like Figures 6 to 10As shown, the cutting moving part 4 includes: a cylinder 401, which is arranged on the supporting top plate 103; a first connecting disk 402, the top end of which is connected to the output end of the cylinder 401; a protective shell 403, one end of which is connected to the bottom end of the first connecting disk 402; a second limiting rod 406, one end of which is connected to the first connecting disk 402; a second connecting disk 405, one end of which is connected to the other end of the second limiting rod 406; a third motor 404, which is arranged in the protective shell 403, and the output end of the third motor 404 passes through the second connecting disk 405 and is connected to the cutting limiting part.

[0036] like Figures 6 to 10 As shown, the cutting limit part includes: an elliptical track 501, connected to the cutting moving part 4; a mounting hole 502, opened on the elliptical track 501, to facilitate the installation and disassembly of the elliptical track 501; an arc-shaped slider 508, sliding in the elliptical track 501; a rotating block 503, connected to the output end of the third motor 404; a telescopic member, one end of which is connected to the rotating block 503, and the other end is connected to the arc-shaped slider 508 via a first connecting square rod 507.

[0037] like Figures 6 to 10 As shown, the telescopic member includes: a connecting sleeve 504, one end of which is connected to the side of the rotating block 503; a limit spring 506, which is arranged in the connecting sleeve 504; a connecting shaft 505, which is passed through the connecting sleeve 504, one end of which is connected to the limit spring 506, and the other end is connected to the first connecting square rod 507.

[0038] like Figures 6 to 10 As shown, the cutting adjustment part includes: a first adjustment groove 603, which is opened on the first connecting square rod 507; an adjustment rod 602, one end of which is inserted into the first adjustment groove 603; a first bolt 604, which is threadedly connected to the first connecting square rod 507 to fix the position of the first connecting square rod 507 and the adjustment rod 602; a second connecting square rod 601, one end of which is connected to the other end of the adjustment rod 602; a second adjustment groove 605, which is opened on the end of the second connecting square rod 601 away from the adjustment rod 602; an adjustment block 607, which is inserted into the second adjustment groove 605 and the bottom end is connected to the cutting knife 7; a second thread, which is threadedly connected to the end of the second connecting square rod 601 away from the adjustment rod 602 to fix the position of the second connecting square rod 601 and the adjustment block 607.

[0039] In the embodiment of the present invention, after the clamping is completed, the first motor 106 is started to drive the rotating disk 104 to rotate along the rotating groove 105, thereby driving the clamping part 2 that clamps the electronic cigarette tube 3 to support the bottom end of the top plate 103 to rotate. When it rotates to the bottom end of the supporting top plate 103, the cylinder 401 is started to drive the first connecting disk 402 to move downward, thereby driving the cutting knife 7 to move downward through the second connecting disk 405, the rotating block 503, the first connecting square rod 507 and the second connecting square rod 601 and other parts, so as to contact the electronic cigarette tube 3 to be cut, and by rotating the first bolt 604, the position of the adjusting rod 602 is adjusted so that the cutting knife 7 is in contact with the outer side of the electronic cigarette tube 3; the third motor 404 is started to drive The rotating block 503 rotates, and the rotating block 503 drives the arc-shaped slider 508 to slide along the elliptical track 501 through the connecting sleeve 504, the limit spring 506, the connecting shaft 505 and the first connecting square rod 507. Since the connecting shaft 505 is connected to the limit spring 506, when the arc-shaped slider 508 slides along the elliptical track 501 with different radii, the limit spring 506 will be driven to extend and retract through the connecting shaft 505; when the arc-shaped slider 508 slides along the elliptical track 501, the adjusting rod 602 will be driven to rotate, thereby driving the second connecting square rod 601 to rotate, and finally driving the cutting knife 7 to rotate and cut along the outer surface of the electronic cigarette tube 3; thereby burrs and flash on the outer surface of the electronic cigarette tube 3 are scraped off.

[0040] When it is necessary to cut the inner wall of the electronic cigarette tube 3, cooperate with the external clamping of the clamping part 2, take the adjusting block 607 out of the second adjusting groove 605 by rotating the second bolt 606, rotate 180 degrees, make the blade of the cutting knife 7 face outward, put the adjusting block 607 into the second adjusting groove 605, and fix it with the second bolt 606.

[0041] By providing an elliptical track 501, the elliptical track 501 is installed on the Durr connecting plate through the fixing piece passing through the mounting hole 502, so that the elliptical track 501 is easy to disassemble; the track path of the elliptical track 501 and the track of the elliptical tube to be processed are in an equidistant magnification relationship, rather than a proportional magnification relationship; so that under the equidistant conversion of the second connecting square rod 601, the moving path of the cutting knife 7 connected to the second connecting square rod 601 is consistent with the processing path of the elliptical tube to be processed; through this design, by replacing different tracks, a variety of different shapes of workpieces to be processed can be processed, thereby increasing the adaptability of the device.

[0042] Working principle: when cutting the outer surface of the electronic cigarette tube 3; first, the electronic cigarette tube 3 is sleeved on the first limiting rod 207, so that the electronic cigarette tube 3 is placed on the placement plate 201, and then the second micro motor 203 is started, thereby driving the bidirectional screw 204 to rotate, and the rotation of the bidirectional screw 204 drives the two threaded sleeves 205 to move away from each other, thereby driving the two bidirectional clamping blocks 206 to move away from each other, until the two bidirectional clamping blocks 206 are both against the inner wall of the electronic cigarette tube 3 to clamp the electronic cigarette tube 3, and at this time, the rotation of the second micro motor 203 is stopped, thereby completing the internal clamping of the electronic cigarette tube 3. The first motor 106 is rotated to drive the rotating disk 104 to rotate, so that the clamped electronic cigarette tube 3 moves to the lower end of the supporting top plate 103; the cylinder 401 is then started to drive the first connecting disk 402 to move downward, so that the cutting knife 7 is driven to move downward through the second connecting disk 405, the rotating block 503, the first connecting square rod 507 and the second connecting square rod 601, so as to contact the electronic cigarette tube 3 to be cut, and the position of the adjusting rod 602 is adjusted by rotating the first bolt 604, so that the cutting knife 7 is in contact with the outer side of the electronic cigarette tube 3. When the third motor 404 is started, the rotating block 503 is driven to rotate. The rotating block 503 drives the arc-shaped slider 508 to slide along the elliptical track 501 through the connecting sleeve 504, the limit spring 506, the connecting shaft 505 and the first connecting square rod 507. When the arc-shaped slider 508 slides along the elliptical track 501, it will drive the adjusting rod 602 to rotate, thereby driving the second connecting square rod 601 to rotate, and finally driving the cutting knife 7 to rotate and cut along the outer surface of the electronic cigarette tube 3; thereby shaving off the burrs and flash on the outer surface of the electronic cigarette tube 3.

[0043] Then cut the inner wall of the electronic cigarette tube 3. After the outer surface cutting of a group of electronic cigarette tubes 3 is completed, move the two bidirectional clamping blocks to the two ends of the placement plate 201, and then place the two sides corresponding to the main axis of the electronic cigarette tube 3 on the placement plate 201 corresponding to the two bidirectional clamping blocks by the staff, and then start the second micro motor 203 to drive the bidirectional screw 204 to rotate. The rotation of the bidirectional screw 204 drives the two threaded sleeves 205 to approach each other, thereby driving the two bidirectional clamping blocks 206 to approach each other, and finally clamp them at the farthest ends of the outer surface of the electronic cigarette tube 3; at the same time, rotate the second bolt 606, take the adjusting block 607 out of the second adjusting groove 605, rotate 180 degrees, so that the blade of the cutting knife 7 faces outward, and then put the adjusting block 607 into the second adjusting groove 605 and fix it with the second bolt 606. The cylinder 401 is started again to drive the first connection plate 402 to move downward, thereby driving the cutting knife 7 to move downward through the second connection plate 405, the rotating block 503, the first connecting square rod 507 and the second connecting square rod 601, so as to contact the electronic cigarette tube 3 to be cut. By rotating the first bolt 604, the position of the adjusting rod 602 is adjusted so that the cutting knife 7 fits the outer side of the electronic cigarette tube 3; when the third motor 404 is started, the rotating block 503 is driven to rotate, and the rotating block 503 drives the arc-shaped slider 508 to slide along the elliptical track 501 through the connecting sleeve 504, the limit spring 506, the connecting shaft 505 and the first connecting square rod 507. When the arc-shaped slider 508 slides along the elliptical track 501, it will drive the adjusting rod 602 to rotate, thereby driving the second connecting square rod 601 to rotate, and finally driving the cutting knife 7 to rotate and cut along the outer surface of the electronic cigarette tube 3; thereby burrs and flash on the inner wall of the electronic cigarette tube 3 are scraped off. Finally, the local trimming work of the electronic cigarette tube 3 is completed.

[0044] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
