The AGV trolley will deliver the loaded boxes of tobacco accessories to different tobacco processing stations. The clamp 2 connected to the execution end of the robot arm at different tobacco processing stations will grab the boxes of tobacco accessories loaded on the AGV trolley, and then move the boxes of tobacco accessories to the processing station through the robot arm. Temporary placement of tobacco accessories position, convenient for operators to place the tobacco accessories on the cigarette production machinery later.

[0003] The clamps 1 and 2 mentioned above are of the same structure. Although the clamps 1 and 2 can complete the process of clamping and releasing tobacco auxiliary materials, the clamps 1 and 2 still have the following defects during use: 1. The structure of the clamps 1 or 2 lacks a mechanism for driving the clamps 1 or 2 to rotate to a certain placement angle or a certain clamping angle. When clamping or placing boxed tobacco auxiliary materials in a certain posture, it is inconvenient to clamp or place the boxed tobacco auxiliary materials in a certain posture, which indirectly affects the process of unloading the boxed tobacco auxiliary materials; 2. There are two cylinders driving the clamp arms in the structure of the clamps 1 or 2 (two cylinders driving the clamp arms: the first cylinder is connected to the first clamp arm, and the second cylinder is connected to the second clamp arm), which not only increases the overall weight of the clamps 1 or 2, but also indirectly increases the load of the mechanical arm connected to the clamps 1 or 2;

[0004] Therefore, it is necessary to improve the structure of the existing clamp one or clamp two for clamping or releasing box-packaged tobacco accessories, so as to solve the problems that the clamp one or clamp two structure lacks a mechanism for driving clamp one or clamp two to rotate to a certain placement angle or a certain clamping angle, which makes it inconvenient to clamp or place box-packaged tobacco accessories in a certain posture, and the existing clamp one or clamp two structure has two cylinders for driving the clamp arms, which indirectly increases the load on the mechanical arm connected to clamp one or clamp two due to the increase in the overall weight of clamp one or clamp two. Summary of the invention

[0005] The purpose of the present invention is to propose a rotating clamping mechanism to solve the problems that the structure of clamp one or clamp two lacks a mechanism for driving clamp one or clamp two to rotate to a certain placement angle or a certain clamping angle, making it inconvenient to clamp or place boxed tobacco accessories in a certain posture, and the existing structure of clamp one or clamp two has two cylinders for driving the clamp arms, which indirectly increases the load on the mechanical arm connected to clamp one or clamp two due to the increase in the overall weight of clamp one or clamp two.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A rotary clamping mechanism comprises a rotary drive member, a support seat, a rotary limit plate, a telescopic drive member and a clamping jaw assembly; the surface wall of the rotary drive member is connected to the top of the support seat through a connecting seat, the rotary drive member has a piston rod that is rotatably connected to the middle of the support seat, a rotary limit plate is sleeved on the piston rod between the rotary drive member and the support seat, the rotary limit member and the rotary limit plate are movably contacted and limited, the surface wall of the rotary limit member is connected to the surface wall of the support seat, the other end of the piston rod of the rotary drive member is connected to the surface wall of the telescopic drive member located below the support seat, and the driving ends of the telescopic drive member are respectively connected to the surface walls of two clamping jaw assemblies.

[0008] Furthermore, the rotation limit plate includes a turntable and a stopper; the turntable is located between the rotation drive member and the support seat, the through hole in the middle of the turntable is socketed with the piston rod of the rotation drive member, at least two stops are provided or threadedly connected on the outer wall of the turntable, and several threaded holes threadedly connected to the stops are provided along the outer wall of the turntable, and the stops are respectively movably contacted with the rotation limit member to limit the position.

[0009] Furthermore, the two stoppers are arranged at intervals along the outer wall of the turntable.

[0010] Furthermore, there are two rotation limiters, which are symmetrically arranged with respect to the support seat, and the two rotation limiters are respectively engaged with the stoppers arranged on the surface wall of the turntable in a movable manner.

[0011] Furthermore, the rotation limiter includes a support and a limit column; a stopper provided on the surface wall of the turntable movably interferes with the limit column, the limit column is provided at one end of the support close to the turntable, and the other end of the support is connected to the surface wall of the support seat.

[0012] Furthermore, the rotary driving member is a rotary cylinder, and the other end of the piston rod of the rotary cylinder is connected to the surface wall of the telescopic driving member located below the support seat.

[0013] Furthermore, the telescopic driving member is a double-acting cylinder, the surface wall of the double-acting cylinder is connected to the other end of the piston rod of the rotary cylinder, and the driving end of the double-acting cylinder is respectively connected to the surface walls of the two clamping jaw assemblies.

[0014] Furthermore, the clamping jaw assembly includes an L-shaped driving block and a clamping jaw adjusting member; the inner wall of the L-shaped driving block is connected to the driving end of the double-acting cylinder, and the L-shaped driving block is threadedly adjustable to the clamping jaw adjusting member.

[0015] Furthermore, the clamping jaw adjustment member includes an adjusting bolt with a nut, a clamping jaw arm and a buffer claw block; the adjusting bolt with a nut is threadedly connected to the L-shaped driving block, and the other end of the adjusting bolt with a nut is connected to the top of the clamping jaw arm, and the inner wall of the clamping jaw arm is connected to the buffer claw block, and the buffer claw block is an L-shaped structure.

[0016] Furthermore, the clamping jaw assembly also includes a guide block; the inner wall of the guide block is connected to the outer wall of the L-shaped driving block, and a slide bar is provided on the inner wall of the guide block, and the slide bar is slidably connected to a slide groove on the outer wall of the clamping jaw arm.

[0017] During the working process, when the rotary clamping mechanism is used to load or unload boxed tobacco accessories (boxed tobacco accessories: a box body containing tobacco accessories), the outer wall of the rotary driving member in the rotary clamping mechanism is first connected to the execution end of the mechanical arm through a bolt assembly, and the mechanical arm located next to the boxed tobacco accessories drives the rotary clamping mechanism to move to the top of the boxed tobacco accessories, and the rotary driving member in the rotary clamping mechanism then drives the clamping jaw assembly to rotate forward to a position matching the placement posture of the boxed tobacco accessories (boxed tobacco accessories: a box body containing tobacco accessories). In the process of the rotary driving member driving the clamping jaw assembly to rotate to a position matching the placement posture of the boxed tobacco accessories, since a rotary limiting disk is sleeved on the piston rod of the rotary driving member, the rotary limiting member and the rotary limiting disk are movably contacted and limited, the rotary limiting disk on the piston rod of the rotary driving member rotates to a position contacting with the rotary limiting member and stops rotating, and the position where the rotary limiting disk contacts with the rotary limiting member is also a position matching the placement posture of the boxed tobacco accessories;

[0018] When the rotary driving member in the rotary clamping mechanism drives the clamping jaw assembly to rotate to a position matching the placement posture of the box-packed tobacco auxiliary materials, the two open clamping jaw assemblies in the rotary clamping mechanism are first driven by the mechanical arm to move down to the box-packed tobacco auxiliary materials, and the box-packed tobacco auxiliary materials are located between the two open clamping jaw assemblies, and then the telescopic driving member connected to the two clamping jaw assemblies is driven to perform a retraction action to drive the two clamping jaw assemblies to clamp the box-packed tobacco auxiliary materials, and then the rotary clamping mechanism with the box-packed tobacco auxiliary materials is moved to the top of the AGV trolley by the mechanical arm, and finally the telescopic driving member connected to the two clamping jaw assemblies is driven to perform an extension action to drive the two clamping jaw assemblies to separate, and the box-packed tobacco auxiliary materials located between the two clamping jaw assemblies are unloaded onto the AGV trolley, and the AGV trolley takes the box-packed tobacco auxiliary materials to the temporary placement position of tobacco auxiliary materials at different tobacco processing stations;

[0019] When the AGV trolley brings the boxed tobacco accessories to the temporary placement position of tobacco accessories at different tobacco processing stations, the mechanical arm at the temporary placement position of tobacco accessories at different tobacco processing stations first drives the two open jaw assemblies in the rotary clamping mechanism to move down to the boxed tobacco accessories, and places the boxed tobacco accessories between the two open jaw assemblies, and then drives the telescopic driving member connected to the two jaw assemblies to perform a retraction action to drive the two jaw assemblies to clamp the boxed tobacco accessories, and then moves the rotary clamping mechanism with the boxed tobacco accessories to the temporary placement position of tobacco accessories at different tobacco processing stations through the mechanical arm. Above the placement position, the rotary driving member in the rotary clamping mechanism drives the clamping jaw assembly to rotate in the opposite direction to a position matching the placement posture of the box-packed tobacco auxiliary materials. During the process in which the rotary driving member drives the clamping jaw assembly to rotate to a position matching the placement posture of the box-packed tobacco auxiliary materials, since a rotary limiting disk is sleeved on the piston rod of the rotary driving member, the rotary limiting member and the rotary limiting disk movably contact and limit the position, the rotary limiting disk on the piston rod of the rotary driving member rotates to a position contacting with the rotary limiting member and stops rotating. The position where the rotary limiting disk contacts with the rotary limiting member is also a position matching the placement posture of the box-packed tobacco auxiliary materials.

[0020] When the rotating driving member in the rotating clamping mechanism drives the clamping jaw assembly to rotate to a position matching the placement posture of the box-packed tobacco accessories, the two open clamping jaw assemblies in the rotating clamping mechanism are first driven by the mechanical arm to move down to the temporary placement position of the tobacco accessories at different tobacco processing stations, and then the telescopic driving member connected to the two clamping jaw assemblies is driven to extend and drive the two clamping jaw assemblies to separate, and the box-packed tobacco accessories located between the two clamping jaw assemblies are unloaded to the temporary placement position of the tobacco accessories at different tobacco processing stations, completing the loading or unloading process of the box-packed tobacco accessories.

[0021] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0022] 1. The present invention connects the surface wall of the rotary driving member to the top of the support seat through a connecting seat, the piston rod of the rotary driving member is rotatably connected to the middle of the support seat, a rotary limit plate is sleeved on the piston rod between the rotary driving member and the support seat, the rotary limit member and the rotary limit plate are movably contacted and limited, the surface wall of the rotary limit member is connected to the surface wall of the support seat, the other end of the piston rod of the rotary driving member is connected to the telescopic driving member located below the support seat, the driving end of the telescopic driving member is respectively connected to the surface walls of the two clamping claw assemblies, and the clamping claw assemblies can be driven by the rotary clamping mechanism driving member to rotate to the position where the box-packed tobacco auxiliary materials are placed. During the process of positioning the tool to match the posture, since the piston rod of the rotary drive member is sleeved with a rotary limit plate, the rotary limit plate movably contacts and limits the position, the rotary limit plate on the piston rod of the rotary drive member stops rotating when it reaches the position where it contacts the rotary limit plate, and the position where the rotary limit plate contacts the rotary limit plate is also a position that matches the placement posture of the box-packed tobacco auxiliary materials. This solves the problem that the existing clamp one or clamp two structure lacks a mechanism to drive clamp one or clamp two to rotate to a certain placement angle or a certain clamping angle, making it inconvenient to clamp or place the box-packed tobacco auxiliary materials with a certain posture.

[0023] 2. The present invention adopts a rotary clamping mechanism composed of a rotary drive member, a support seat, a rotary limit plate, a telescopic drive member, a clamping jaw assembly and a rotary limit member. During the process of clamping or releasing the boxed tobacco auxiliary materials with the rotary clamping mechanism, only one telescopic drive member is used to drive the two clamping jaw assemblies to open or close, so as to complete the clamping or releasing of the boxed tobacco auxiliary materials. In this way, a telescopic drive member in the rotary clamping mechanism structure not only reduces the overall weight of the rotary clamping mechanism, but also reduces the load of the mechanical arm connected to the rotary clamping mechanism, thereby solving the problem that in the existing clamp one or clamp two structure, there are two cylinders driving the clamp arms, and the overall weight of the clamp one or clamp two is increased, which indirectly increases the load of the mechanical arm connected to the clamp one or clamp two.

[0024] 3. The present invention uses a rotary clamping mechanism connected to a robot arm to load boxed tobacco accessories onto an AGV trolley, which then takes the boxed tobacco accessories to temporary placement locations for tobacco accessories at different tobacco processing stations. A rotary clamping mechanism located at the temporary placement locations for tobacco accessories at different tobacco processing stations and connected to another robot arm unloads the boxed tobacco accessories to the temporary placement locations for tobacco accessories at different processing stations, eliminating the need for manual handling by operators and reducing the labor intensity of operators.

[0025] 4. The present invention arranges the jaw adjusting part in the jaw assembly to be adjustable in the vertical direction. The specific structure of the adjustable jaw adjusting part is that an adjusting bolt with a nut is threadedly connected to an L-shaped driving block, and the other end of the adjusting bolt with a nut is connected to the outer wall of the jaw arm. When the two jaw assemblies clamp tobacco accessories in boxes of different heights, the adjusting bolt threadedly connected to the L-shaped driving block can be turned according to the height of the box containing the tobacco accessories, so that the jaw arm connected to the other end of the adjusting bolt can be moved upward or downward in the vertical direction to a position matching the height of the box containing the tobacco accessories, thereby meeting the subsequent clamping of the two jaw assemblies on the tobacco accessories in boxes of different heights.

[0026] 5. The present invention has two blocks threadedly connected to the outer wall of the turntable, and a plurality of threaded holes threadedly connected to the blocks are arranged along the outer wall of the turntable, and the blocks are respectively movably contacted and limited with the rotation limit pieces, so that in the process of the rotating clamping mechanism driving part driving the clamping jaw assembly to rotate to different positions matching the placement posture of the box tobacco auxiliary materials, the rotating clamping mechanism driving part can drive the clamping jaw assembly to rotate to different positions matching the placement posture of the box tobacco auxiliary materials, and the block is threadedly connected to the outer wall of the turntable corresponding to the various positions where the rotating clamping mechanism driving part drives the clamping jaw assembly to rotate to match the placement posture of the box tobacco auxiliary materials, and then cooperate with the rotation limit piece to movably contact and limit the blocks installed on the outer wall of the turntable, so that the rotating clamping mechanism driving part drives the clamping jaw assembly to rotate to various positions matching the placement posture of the box tobacco auxiliary materials and stop, so as to meet the demand for rotating the clamping jaw assembly to various positions matching the placement posture of the box tobacco auxiliary materials.

DETAILED DESCRIPTION

[0036] like Figure 1-8 In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is 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.

[0037] Example

[0038] The existing clamp 1 and clamp 2 have the following defects in the process of clamping or releasing the tobacco auxiliary materials in the box: 1. In the structure of clamp 1 or clamp 2, there are two cylinders on the clamp frame for driving the clamp arms to move closer or farther away (two cylinders driving the clamp arms: the first cylinder is connected to the first clamp arm, and the second cylinder is connected to the second clamp arm). The two cylinders not only increase the overall weight of clamp 1 or clamp 2, but also indirectly increase the load of the mechanical arm connected to clamp 1 or clamp 2;

[0039] Second, there is a lack of a mechanism in the structure of clamp one or clamp two to drive clamp one or clamp two to rotate to a certain placement angle or a certain clamping angle, which makes it inconvenient to clamp or place boxed tobacco accessories in different postures, indirectly affecting the unloading process of boxed tobacco accessories.

[0040] Therefore, the present application designs a rotating clamping mechanism to solve the problem that the existing clamp one or clamp two structure has two cylinders driving the clamp arms, which indirectly increases the load on the mechanical arm connected to clamp one or clamp two due to the increased overall weight of clamp one or clamp two, and the clamp one or clamp two structure lacks a mechanism to drive clamp one or clamp two to rotate to a certain placement angle or a certain clamping angle, making it inconvenient to clamp or place boxed tobacco accessories in a certain posture.

[0041] For details, please refer to Figure 1 and Figure 2A rotary clamping machine comprises a rotary driving member 1, a support seat 2, a rotary limiting disk 4, a telescopic driving member 5 and a clamping jaw assembly 6; the surface wall of the rotary driving member 1 is connected to the top of the support seat 2 through a connecting seat 9, and the piston rod 3 of the rotary driving member 1 is rotatably connected to the middle part of the support seat 2; a rotary limiting disk 4 is sleeved on the piston rod 3 between the rotary driving member 1 and the support seat 2, and the rotary limiting member 19 is movably abutted against the rotary limiting disk 4 for limiting, and the surface wall of the rotary limiting member 19 is connected to the surface wall of the support seat 2; the other end of the piston rod 3 of the rotary driving member 1 is connected to the surface wall of the telescopic driving member 5 located below the support seat 2; the driving ends of the telescopic driving member 5 are respectively connected to the surface walls of the two clamping jaw assemblies 6.

[0042] In actual use, when the rotary clamping mechanism is used to load or unload boxed tobacco accessories (boxed tobacco accessories: a box containing tobacco accessories), the outer wall of the rotary driving member 1 in the rotary clamping mechanism is first connected to the execution end of the mechanical arm through a bolt assembly, and the mechanical arm located next to the boxed tobacco accessories drives the rotary clamping mechanism to move to the top of the boxed tobacco accessories, and the rotary driving member 1 in the rotary clamping mechanism then drives the clamping jaw assembly 6 to rotate forward to a position matching the placement posture of the boxed tobacco accessories, and the rotary driving member 1 drives the clamping jaw assembly 6 to rotate forward to a position matching the placement posture of the boxed tobacco accessories. During the process of rotating the member 6 to a position matching the placement posture of the box-packed tobacco auxiliary materials (box-packed tobacco auxiliary materials: a box body containing tobacco auxiliary materials), since the piston rod of the rotary driving member 1 is sleeved with a rotary limit plate 4, the rotary limit plate 19 movably contacts and limits the position with the rotary limit plate 4, and the rotary limit plate 4 on the piston rod 3 of the rotary driving member 19 rotates to a position contacting with the rotary limit plate 19 and stops rotating, the position where the rotary limit plate 4 contacts with the rotary limit plate 19 is also a position matching the placement posture of the box-packed tobacco auxiliary materials;

[0043] When the rotary driving member 1 in the waiting rotary clamping mechanism drives the clamping jaw assembly 6 to rotate to a position matching the placement posture of the box-packed tobacco auxiliary materials, the two open clamping jaw assemblies 6 in the rotary clamping mechanism are first driven by the mechanical arm to move down to the box-packed tobacco auxiliary materials, and the box-packed tobacco auxiliary materials are located between the two open clamping jaw assemblies 6, and then the telescopic driving member 5 connected to the two clamping jaw assemblies 6 is driven to perform a retraction action to drive the two clamping jaw assemblies 6 to clamp the box-packed tobacco auxiliary materials, and then the rotary clamping mechanism with the box-packed tobacco auxiliary materials is moved to the top of the AGV trolley by the mechanical arm, and finally the telescopic driving member 5 connected to the two clamping jaw assemblies 6 is driven to perform an extension action to drive the two clamping jaw assemblies 6 to separate, and the box-packed tobacco auxiliary materials located between the two clamping jaw assemblies 6 are unloaded onto the AGV trolley, and the AGV trolley takes the box-packed tobacco auxiliary materials to the temporary placement position of tobacco auxiliary materials at different tobacco processing stations;

[0044] When the AGV trolley brings the boxed tobacco accessories to the temporary placement position of tobacco accessories at different tobacco processing stations, the robotic arm at the temporary placement position of tobacco accessories at different tobacco processing stations first drives the two open jaw assemblies 6 in the rotary clamping mechanism to move down to the boxed tobacco accessories, and places the boxed tobacco accessories between the two opened jaw assemblies 6, and then drives the telescopic driving member 5 connected to the two jaw assemblies 6 to perform a retraction action to drive the two jaw assemblies 6 to clamp the boxed tobacco accessories, and then moves the rotary clamping mechanism with the boxed tobacco accessories to the top of the temporary placement position of tobacco accessories at different tobacco processing stations through the robotic arm, and rotates the rotary clamping mechanism to move the two jaw assemblies 6 to the top of the temporary placement position of tobacco accessories at different tobacco processing stations. The rotary drive member 1 in the rotating clamping mechanism then drives the clamping jaw assembly 6 to rotate in the opposite direction to a position that matches the placement posture of the box-packed tobacco auxiliary materials. During the process in which the rotary drive member drives the clamping jaw assembly 6 to rotate to a position that matches the placement posture of the box-packed tobacco auxiliary materials, since the rotary drive member 1 has a piston rod 3 sleeved with a rotary limit plate 4, the rotary limit plate 19 movably contacts and limits the position with the rotary limit plate 4, and the rotary limit plate 4 on the piston rod 3 of the rotary drive member 19 rotates to a position that contacts the rotary limit plate 19 and stops rotating. The position where the rotary limit plate 4 contacts the rotary limit plate 19 is also a position that matches the placement posture of the box-packed tobacco auxiliary materials.

[0045] When the rotating driving member 1 in the rotating clamping mechanism drives the clamping jaw assembly 6 to rotate to a position matching the placement posture of the box-packed tobacco accessories, the two open clamping jaw assemblies 6 in the rotating clamping mechanism are first driven by the mechanical arm to move down to the temporary placement position of tobacco accessories at different tobacco processing stations, and then the telescopic driving member 5 connected to the two clamping jaw assemblies 6 is driven to extend and drive the two clamping jaw assemblies 6 to separate, and the box-packed tobacco accessories located between the two clamping jaw assemblies 6 are unloaded to the temporary placement position of tobacco accessories at different tobacco processing stations, completing the loading or unloading process of the box-packed tobacco accessories.

[0046] In the process of loading or unloading the box-packed tobacco auxiliary materials by the rotary clamping mechanism, only one telescopic driving member 5 is used to drive the two clamping jaw assemblies 6 to open or close, so as to complete the clamping or release of the box-packed tobacco auxiliary materials. In this way, a telescopic driving member 5 in the structure of the rotary clamping mechanism not only reduces the overall weight of the rotary clamping mechanism, but also indirectly reduces the load of the mechanical arm connected to the rotary clamping mechanism. In addition, in the process of the rotary clamping mechanism rotary driving member 1 driving the clamping jaw assembly 6 to rotate to a position matching the placement posture of the box-packed tobacco auxiliary materials, due to the rotary driving member 1 having A rotation limit plate 4 is sleeved on the piston rod, and the rotation limit member 19 is movably abutted against the rotation limit plate 4 to limit the position. Then, the rotation limit plate 4 on the piston rod 3 of the rotation driving member 19 rotates to the position abutting against the rotation limit member 19 and stops rotating. The position where the rotation limit plate 4 abuts against the rotation limit member 19 is also a position matching the placement posture of the box-packed tobacco auxiliary materials, thereby solving the problem that the existing clamp one or clamp two structure lacks a mechanism to drive clamp one or clamp two to rotate to a certain placement angle or a certain clamping angle, making it inconvenient to clamp or place the box-packed tobacco auxiliary materials in a certain posture.

[0047] See also Figure 1 , Figure 3 and Figure 4 The rotating limit plate 4 that movably contacts and limits the rotating limit member 19 includes a turntable 7 and a stopper 8; wherein the turntable 7 is used to be sleeved with the piston rod 3 of the rotating driving member 1 so as to drive the turntable 7 to rotate through the rotating piston rod 3; the stopper 8 is used to be connected to the outer wall of the turntable 7 so as to rotate the stopper 8 to the rotating limit member 19 for contact and limit through the rotating turntable 7.

[0048] Specifically, the disc-shaped turntable 7 is located between the rotary drive member 1 and the L-shaped support seat 2. There is a certain interval between the disc-shaped turntable 7 and the two L-shaped support seats 2 to prevent the disc-shaped turntable 7 from interfering with the two L-shaped support seats 2 during rotation. A through hole is also provided in the middle of the disc-shaped turntable 7, which is sleeved with the piston rod 3 of the rotary drive member 1. At least two columnar stops 8 are arranged on the outer wall of the turntable 7. The two columnar stops 8 are arranged at intervals along the outer wall of the disc-shaped turntable 7. The columnar stops 8 are respectively movably abutted against and limited by the rotation limit members 19. There are two rotation limit members 19, which are symmetrically arranged about the support seat 2. The two rotation limit members are respectively limited by the two stops 8 arranged on the surface wall of the turntable 7.

[0049] In actual use, when the rotary drive member 1 drives the two-hand claw assembly 6 to rotate to the clamping position matching the placement posture of the box-packed tobacco auxiliary materials, the rotary drive member 1 will drive the turntable 7 with the block 8 and the two-hand claw assembly 6 connected to the driving end of the telescopic drive member 5 to rotate forward through the piston rod 3. During this rotation process, one of the blocks 8 on the turntable 7 will abut against the rotation limit member 19 for limiting the position. At this time, the turntable 7, the piston rod 3 connected to the turntable 7 and the two-hand claw assembly 6 connected to the driving end of the telescopic drive member 5 stop rotating. Since the block 8 that abuts against the rotation limit member 19 for limiting the position is set on the outer wall of the turntable 8, the position of the rotary drive member 1 driving the two-hand claw assembly 6 to rotate to the clamping position matching the placement posture of the box-packed tobacco auxiliary materials is completed. The process of the rotary drive member 1 driving the two-hand claw assembly 6 to rotate to the clamping position matching the placement posture of the box-packed tobacco auxiliary materials and stopping is completed.

[0050] When the rotary drive member 1 drives the two-claw assembly 6 to rotate to the release position matching the placement posture of the box-packed tobacco accessories (box-packed tobacco accessories: a box body containing tobacco accessories), the rotary drive member 1 will drive the turntable 7 with the block 8 and the two-claw assembly 6 connected to the driving end of the telescopic drive member 5 to rotate in the opposite direction through the piston rod 3. During this rotation process, the other block 8 on the turntable 7 will abut against and limit the other rotation limit member 19. At this time, the turntable 7, the piston rod 3 connected to the turntable 7 and the two-claw assembly 6 connected to the driving end of the telescopic drive member 5 stop rotating. Since the other block 8 abutting against and limiting the other rotation limit member 19 is set on the outer wall of the turntable 8, the position of the rotary drive member 1 driving the two-claw assembly 6 to rotate to the release position matching the placement posture of the box-packed tobacco accessories is completed.

[0051] It should be noted that, in order to prevent the stopper 8 on the turntable 7 from interfering with the rotation of the L-shaped support seat 2 , a certain interval is reserved between the stopper 8 and the L-shaped support seat 2 .

[0052] In this example, in order to meet the requirement that the driving component 1 drives the two-hand claw assembly 6 to rotate to different clamping / release positions that match the placement posture of the box-packed tobacco accessories, the connection method between the disc-shaped turntable 7 and the columnar stopper 8 can also be: the outer wall of the disc-shaped turntable is threadedly connected with a columnar stopper 8, and a number of threaded holes threadedly connected to the columnar stopper 8 are arranged at intervals along the outer wall of the disc-shaped turntable 7, and the columnar stopper 8 is respectively movably contacted and limited by the rotation limiter 19.

[0053] In actual use, in the process of the rotary clamping mechanism driving part 1 driving the clamping jaw assembly 6 to rotate to different positions matching the placement posture of the box-packed tobacco accessories, the rotary clamping mechanism driving part 1 can drive the clamping jaw assembly 6 to rotate to different positions matching the placement posture of the box-packed tobacco accessories, and the stopper 8 can be threadedly connected to the outer wall of the turntable 7 corresponding to the various positions that the rotary clamping mechanism driving part drives the clamping jaw assembly to rotate to match the placement posture of the box-packed tobacco accessories, and then the rotary limiter 19 cooperates with the stopper 8 threadedly connected to the outer wall of the turntable 7 to perform active resistance limiting, and the rotary clamping mechanism driving part drives the clamping jaw assembly 6 to rotate to various positions matching the placement posture of the box-packed tobacco accessories and stop, thereby meeting the demand for rotating the clamping jaw assembly to various positions matching the placement posture of the box-packed tobacco accessories.

[0054] See also Figure 1 , Figure 2 and Figure 4 The rotation limit member 4 that is in contact with the stop block 8 on the outer wall of the disc-shaped turntable 7 and limits the position includes a support 10 and a limit column 11; wherein the support 10 is used for detachable connection with the support base 2 on the one hand, and is used as a base for installing the limit column 11 on the other hand; the limit column 11 is used for contacting and limiting the stop block 8 set on the outer wall of the turntable 7.

[0055] Specifically, the columnar stopper 8 provided on the outer wall of the disc-shaped turntable 7 movably interferes with the columnar limit column 11, and the columnar limit column 11 is located between the rotating drive member 1 and the support seat 2. The columnar limit column 11 is provided at one end of the support 10 close to the turntable 7, and the other end of the support 10 is connected to the surface wall of the support seat 2.
