Description

Technical Field

[0001] This utility model relates to the field of cigarette clamping technology, and in particular to a precision cigarette clamping device based on electromagnetic pulse drive. Background Technology

[0002] During the tobacco product manufacturing process, the cigarettes produced by the cigarette rolling machine are typically subjected to physical performance testing. This is done to understand the physical properties of the cigarettes produced in the current batch, allowing for timely adjustments to the rolling machine's production process and further improving the quality of the cigarettes. The physical performance testing process involves first clamping and fixing the cigarettes to be tested, and then using testing instruments to measure the various physical indicators of the cigarettes.

[0003] In the process of clamping cigarettes, there are generally two existing methods: 1. Using rollers or elastic components to clamp the cigarette at the detection position; 2. Using a pneumatic rubber sleeve structure to fix the cigarette. Although these two methods can clamp cigarettes, they still have the following drawbacks in actual cigarette clamping:

[0004] (1) When using rollers to clamp cigarettes, since the size of the cigarettes clamped by the rollers is fixed, when it is necessary to change the cigarette specifications during the inspection process, the personnel not only need to change them manually, but also the clamp replacement steps are cumbersome and have a low degree of automation. Furthermore, they cannot be automatically adjusted according to the cigarette specifications (cannot be automatically adjusted according to the cigarette specifications: cannot automatically match roller clamps suitable for clamping different specifications according to the cigarette specifications).

[0005] (2) When using a pneumatic rubber sleeve structure to clamp cigarettes, the clamping accuracy cannot be precisely controlled, and there may be over-clamping or insufficient clamping.

[0006] Therefore, it is necessary to improve the existing cigarette clamping structure to solve the problems of the existing clamping device not being able to automatically adjust according to the cigarette specifications and the poor clamping accuracy. Utility Model Content

[0007] The purpose of this invention is to propose a precision cigarette clamping device based on electromagnetic pulse drive, so as to solve the problems of existing clamping devices not being able to automatically adjust according to cigarette specifications and having low clamping accuracy.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] A precision cigarette clamping device based on electromagnetic pulse drive includes:

[0010] case;

[0011] The coil winding is provided around the inner wall of the housing.

[0012] A rotating magnetic ring is arranged inside the coil winding, with a gap between the rotating magnetic ring and the coil winding.

[0013] The cigarette holder ring is enclosed inside the rotating magnetic ring. Both ends of the cigarette holder ring are fixedly connected to the shell, and the rotating magnetic ring is rotatably connected to the cigarette holder ring.

[0014] The cigarette clamping block has its first end rotatably connected to the inner wall of the rotating magnetic ring, and each cigarette clamping block is rotatably connected to each guide slot opened on the side wall of the cigarette receiving ring. The second end of the cigarette clamping block extends from the guide slot on the side wall of the cigarette receiving ring to the cigarette placement area defined by the cigarette receiving ring.

[0015] Preferably, the housing includes end caps and a cylindrical body; the cylindrical body is a cylindrical cavity structure with open ends, and end caps are connected to the open ends of the cylindrical body respectively. The end caps and the cylindrical body together define a space for assembling the coil winding, the rotating magnetic ring, the cigarette holder ring, and the cigarette clamping block.

[0016] Preferably, the coil winding includes a silicon steel sheet skeleton and copper wire; the silicon steel sheet skeleton is arranged in a ring on the inner wall of the cylinder, and copper wire is wound on the silicon steel sheet skeleton. A rotating magnetic ring is arranged inside the silicon steel sheet skeleton with copper wire wound on it, and a gap is left between the rotating magnetic ring and the copper wire.

[0017] Preferably, the rotating magnetic ring body includes a first magnetic ring, a second magnetic ring, and a magnetic ring cylinder; the first magnetic ring is located between the magnetic ring cylinder and the copper wire, and the second magnetic ring is also located between the magnetic ring cylinder and the copper wire. Both the second magnetic ring and the first magnetic ring are sleeved on the magnetic ring cylinder, and the first magnetic ring and the second magnetic ring are arranged from top to bottom along the outer wall of the magnetic ring cylinder.

[0018] Preferably, the rotating magnetic ring body further includes a first annular step, which is respectively opened at the open ends of the magnetic ring cylinder. The two first annular steps are respectively fitted inside the outer ring of the bearing. The inner rings of the two bearings are respectively fitted outside the outer walls near the two ends of the cigarette holder ring body. The two ends of the cigarette holder ring body are respectively fixedly connected to the inner walls of the end caps.

[0019] Preferably, a second annular step is provided on the inner wall of each end cap. The second annular step is connected to a through hole on the end cap. The through hole is connected to both ends of the cigarette holder ring. The axis of the through hole is on the same horizontal line as the axis of the cigarette holder ring.

[0020] Preferably, the second annular step corresponds to the first annular step, and the second annular step and the first annular step together define a space for assembling the bearing.

[0021] Preferably, the rotating magnetic ring also includes an arc-shaped groove located on the inner wall of the magnetic ring cylinder between the two first annular steps. The arc-shaped groove is provided in three annular intervals along the inner wall of the magnetic ring cylinder. One end of each cigarette clamping block is rotatably connected to each arc-shaped groove. Each cigarette clamping block is rotatably connected to a connecting shaft fixedly connected to each guide slot. The other end of each cigarette clamping block extends from each guide slot on the side wall of the cigarette receiving ring to the cigarette placement area defined by the cigarette receiving ring.

[0022] Prior to this, the three cigarette clamping blocks define a space for clamping the cigarette.

[0023] Preferably, a precision cigarette clamping device based on electromagnetic pulse drive also includes a rotating magnetic ring rotation limiting block, which is connected to the inner wall of the groove on the outer wall of the cigarette receiving ring. The rotating magnetic ring rotation limiting block is in motion against and limited by the limiting groove. The limiting groove is opened on the first annular stepped platform on the magnetic ring cylinder, and the end of the limiting groove near the cigarette receiving ring is open.

[0024] In the engineering process, when using an electromagnetic pulse-driven precision cigarette clamping device to clamp cigarettes of different specifications (different specifications of cigarettes: cigarettes of different thicknesses), the cigarettes to be clamped are first placed into a space defined by three cigarette clamping blocks within the cigarette receiving ring. Then, the computer automatically calculates the rotation angle data required for the rotating magnetic ring to complete the clamping of the cigarettes based on the specification information of the cigarettes preset by the user in the system. Based on this rotation angle data, and according to the coil's number of stages, the required number of pulse signals is calculated. The controller then sends a corresponding number of high-frequency pulse signals to the energized coil windings. This energizes the coil windings to generate a magnetic field, causing the rotating magnetic ring to rotate to the position where the cigarette clamping blocks hold the cigarettes to be clamped. Driven by the rotation of the magnetic ring, the three cigarette clamping blocks move into space until they just begin to clamp the cigarettes. After each cigarette clamping block reaches the point of contact with the cigarette (meaning it has just reached its position and is precisely clamping the cigarette), the resistance of each clamping block increases. This causes the coil windings to... The current in the coil increases; after the controller, which controls the coil winding, detects the increased current signal, it continuously sends a locking current to the coil. The coil then continuously flows a stable locking current, stabilizing the magnetic field generated by the coil. Under the influence of this stable magnetic field, the rotating magnetic ring causes the cigarette clamping blocks to maintain a certain clamping torque, clamping the cigarettes to be tested that have been pre-placed in the cigarette clamping space. After the cigarettes to be clamped are tested, the computer sends a zero signal to the controller, which then reverses the current flow. The reverse-energized coil drives the rotating magnetic ring to move the cigarette clamping blocks... The magnetic field that releases the cigarette causes the rotating magnetic ring to rotate each cigarette clamping block connected to it to a fully open position (fully open position: the position where each cigarette clamping block does not clamp a cigarette). The three cigarette clamping blocks then release the pre-clamped cigarettes, completing the process of clamping cigarettes of different specifications using an electromagnetic pulse-driven precision cigarette clamping device. This not only improves the clamping accuracy of the electromagnetic pulse-driven precision cigarette clamping device but also indirectly enhances its practicality by considering the clamping process of different cigarette specifications.

[0025] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0026] This invention comprises a housing, a coil winding, a rotating magnetic ring, a cigarette holder ring, and a cigarette clamping block, forming a precision cigarette clamping device based on electromagnetic pulse drive. This precision cigarette clamping device based on electromagnetic pulse drive can not only clamp cigarettes of different specifications, but also has high clamping and positioning accuracy, solving the problems of existing cigarette clamping devices that cannot automatically adjust according to cigarette specifications and have low clamping accuracy.

Detailed Implementation

[0042] like Figure 1-14 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.

[0043] Example

[0044] The existing cigarette clamping devices still have the following defects: (1) When using rollers to clamp cigarettes, since the size of the cigarettes clamped by the rollers is fixed, when it is necessary to change the cigarette specifications during the inspection process, the personnel not only need to manually change them, but also the clamping replacement steps are cumbersome and the degree of automation is low. Furthermore, they cannot be automatically adjusted according to the cigarette specifications (cannot be automatically adjusted according to the cigarette specifications: cannot automatically match roller clamps suitable for clamping different specifications according to the cigarette specifications).

[0045] (2) When using a pneumatic rubber sleeve structure to clamp cigarettes, the clamping accuracy cannot be precisely controlled, and there may be over-clamping or insufficient clamping.

[0046] Therefore, this application proposes a precision cigarette clamping device based on electromagnetic pulse drive to solve the problems caused by the existing methods of clamping cigarettes using rollers or pneumatic rubber sleeves, which cannot automatically adjust according to the cigarette specifications and have low clamping accuracy.

[0047] For details, please refer to Figure 1 and Figure 2 A precision cigarette clamping device based on electromagnetic pulse drive includes a housing 1, a coil winding 2, a rotating magnetic ring 3, a cigarette receiving ring 4, and a cigarette clamping block 5. The inner wall of the housing 1 is circumferentially fitted with the coil winding 2, i.e., the inner wall of the housing 1 is connected to the coil winding 2. The rotating magnetic ring 3 is arranged inside the coil winding 2, with a gap between the rotating magnetic ring 3 and the coil winding 2. The cigarette receiving ring 4 is arranged inside the rotating magnetic ring 3, with both ends of the cigarette receiving ring 4 fixedly connected to both ends of the housing 1. The rotating magnetic ring 3 and the cigarette receiving ring 4 rotate... The first end of each cigarette clamping block 5 is rotatably connected to the inner wall of the rotating magnetic ring 3, and each cigarette clamping block 5 is rotatably connected to each guide slot 6 opened on the side wall of the cigarette receiving ring 4. The second end of the cigarette clamping block 5 extends from the guide slot 6 on the side wall of the cigarette receiving ring 4 to the cigarette placement area 7 defined by the cigarette receiving ring 4. The coil in the coil winding 2 is connected to the power line, and the power line is electrically connected to the coil in the coil winding 2 inside the housing 1 through the through hole on the outer wall of the cylinder 9 in the housing 1. A controller is electrically connected to the power line. The controller is connected in series on the power line. The computer is electrically connected to the controller. The computer is used to automatically calculate the angle data that the rotating magnetic ring needs to rotate when the cigarette clamping block completes the clamping of the cigarette based on the user-preset specifications of the cigarette to be clamped in the system. Then, based on the angle data that the rotating magnetic ring needs to rotate when the cigarette clamping block completes the clamping of the cigarette, and based on the number of coil stages, it calculates the required number of pulse signals, and sends the corresponding number of high-frequency pulse signals to the controller that controls the coil winding to be energized, and sends a zero signal to the controller. The controller is used to receive the corresponding number of high-frequency pulse signals sent by the computer to control the coil winding to generate a magnetic field that drives the rotating magnetic ring to rotate to the position where the cigarette clamping block clamps the cigarette to be clamped. The controller is also used to receive the zero signal sent by the computer to control the coil winding to be energized in reverse. The reverse-energized coil generates a magnetic field that drives the rotating magnetic ring to move the cigarette clamping block to release the cigarette. After detecting the increase in coil current, the controller continuously sends a locking current to the coil.

[0048] In practical applications, a precision cigarette clamping device based on electromagnetic pulse drive is used to clamp cigarettes of different specifications (different specifications of cigarettes: cigarettes of different thicknesses). First, the cigarettes of different specifications to be clamped are placed into a space 21 defined by three cigarette clamping blocks 5 within the cigarette receiving ring 4. Then, with the help of a computer, based on the specification information of the cigarettes to be clamped preset by the user in the computer system, the computer automatically calculates the angle data of rotation required for the rotating magnetic ring 3 to complete the clamping of the cigarettes. Then, based on the angle data of rotation required for the rotating magnetic ring 3 to complete the clamping of the cigarettes by the cigarette clamping blocks, and based on the number of coil stages, the required number of pulse signals is calculated and then sent to the control coil winding 2. The controller, with its coil energized, sends a corresponding number of high-frequency pulse signals. The coil winding 2 is then energized to generate a magnetic field, causing the rotating magnetic ring 3 to rotate to the position where the cigarette clamping block 5 holds the cigarette to be clamped. Driven by the rotation of the magnetic ring 3, the three cigarette clamping blocks 5 move into space 21 to the position where they just begin to clamp the cigarette to be held. After each cigarette clamping block 5 reaches the point of contact with the cigarette to be clamped (meaning it has just reached its position and is precisely clamping the cigarette), the resistance of each cigarette clamping block 5 increases, which increases the current in the coil winding 2. After the controller energizing the coil in winding 2 detects an increase in coil current, it continuously sends a locking current to the coil. This stable locking current flows through the coil, stabilizing the magnetic field it generates. Under this stable magnetic field, the rotating magnetic ring 3 causes the cigarette clamping blocks 5 to maintain a certain clamping torque, clamping the cigarettes to be tested that have been pre-placed in the cigarette clamping space 21. After the cigarettes to be clamped are tested, the computer sends a zero signal to the controller, causing the controller energizing the coil in winding 2 to reverse the energization. The reverse-energized coil generates a magnetic field that drives the rotating magnetic ring 3 to release the cigarette clamping blocks 5 from the cigarettes. Under this magnetic field, the rotating magnetic ring 5... The three cigarette clamping blocks 5, connected to the rotating magnetic ring 5, rotate to the fully open position (fully open position: the position where each cigarette clamping block does not clamp a cigarette). Then, the three cigarette clamping blocks 5 release the cigarettes that were previously clamped, thus completing the process of clamping cigarettes of different specifications using an electromagnetic pulse-driven precision cigarette clamping device. In this way, not only is the clamping accuracy of the electromagnetic pulse-driven precision cigarette clamping device improved, but it can also indirectly improve the practicality of an electromagnetic pulse-driven precision cigarette clamping device by adjusting the clamping process of cigarettes of different specifications, solving the problems of existing cigarette clamping devices not being able to automatically adjust according to cigarette specifications and having low clamping accuracy.

[0049] Please see Figure 3 and Figure 4To provide protection for the coil winding 2, the rotating magnetic ring 3, the cigarette holder ring 4, and the cigarette clamping block 5, the housing 1 includes end caps 8 and a cylindrical body 9; wherein, the end caps 8 are respectively connected to the open ends of the cylindrical body 9, and the two end caps 8 and the cylindrical body 9 define a space 10 for protecting the coil winding 2, the rotating magnetic ring 3, the cigarette holder ring 4, and the cigarette clamping block 5.

[0050] Specifically, the cylinder 9 is a cylindrical cavity structure with open ends. End caps 8 are connected to the open ends of the cylinder 9. The end caps 8 and the cylinder 9 together define a space 10 for protecting the coil winding 2, the rotating magnetic ring 3, the cigarette holder ring 4, and the cigarette clamping block 5.

[0051] In practical applications, the inner wall of the housing 1 is provided with a coil winding 2, that is, the inner wall of the housing 1 is connected to the coil winding 2. The rotating magnetic ring 3 is arranged inside the coil winding 2, and a gap is left between the rotating magnetic ring 3 and the coil winding 2. The cigarette holder ring 4 is arranged inside the rotating magnetic ring 3. The two ends of the cigarette holder ring 4 are fixedly connected to the two ends of the housing 1, and the rotating magnetic ring 3 and the cigarette holder ring 4 are rotatably connected. The first end of each cigarette holder block 5 is rotatably connected to the inner wall of the rotating magnetic ring 3, and each cigarette holder block 5 is respectively connected to the cigarette holder ring 4. Each guide slot 6 on the side wall of the cigarette receiving ring 4 is rotatably connected. The second end of the cigarette clamping block 5 extends from the guide slot 6 on the side wall of the cigarette receiving ring 4 into the cigarette placement area 7 defined by the cigarette receiving ring 4. That is, the protective coil winding 2, the rotating magnetic ring 3, the cigarette receiving ring 4 and the cigarette clamping block 5 are all located in the protective space 10 defined by the end caps 8 and the cylinder 9. The protective space 10 can play a certain protective role for the protective coil winding 2, the rotating magnetic ring 3, the cigarette receiving ring 4 and the cigarette clamping block 5.

[0052] Please see Figure 5 The coil winding 2, used to drive the rotating magnetic ring 3 to clamp the cigarette with the cigarette clamping block 5 or to drive the rotating magnetic ring 3 to release the cigarette with the cigarette clamping block 5, includes a silicon steel sheet skeleton 11 and copper wire. The silicon steel sheet skeleton 11 is arranged in a ring on the inner wall of the cylinder 9 and is fixedly connected to the inner wall of the cylinder 9. A copper wire winding (copper wire winding: coil) is wound on the silicon steel sheet skeleton 11. The rotating magnetic ring 3 is arranged in a ring inside the silicon steel sheet skeleton 11 with the copper wire winding. Specifically, the rotating magnetic ring 3 is arranged in a ring defined by the copper wire winding. There is a gap between the rotating magnetic ring 3 and the copper wire, which is not very wide. The copper wire winding can be composed of a combination of copper wire windings with different magnetic field directions.

[0053] In practical applications, if it is necessary to drive the rotating magnetic ring 3 to clamp the cigarettes with the cigarette clamping blocks 5, firstly, cigarettes of different specifications to be clamped are placed in the space 21 defined by the three cigarette clamping blocks 5 within the cigarette receiving ring 4. Then, with the help of a computer, based on the specification information of the cigarettes to be clamped preset by the user in the computer system, the angle data of rotation of the rotating magnetic ring 3 required for the cigarette clamping blocks 5 to clamp the cigarettes to be clamped is automatically calculated. Then, based on the angle data of rotation of the rotating magnetic ring 3 required for the cigarette clamping blocks to clamp the cigarettes to be clamped, and based on the number of coil stages, the required number of pulse signals is calculated. Then, the corresponding number of high-frequency pulse signals are sent to the controller that controls the coil winding 2 to energize the coil, thereby generating a magnetic field that drives the rotating magnetic ring 3 to rotate to the position where the cigarette clamping blocks 5 clamp the cigarettes to be clamped. Under the rotation of the rotating magnetic ring 3, the three cigarette clamping blocks 5... The components move into space 21 until the cigarette clamping block 5 just clamps the cigarette to be clamped. After each cigarette clamping block 5 moves to the position where it just clamps the cigarette to be clamped (after moving to the position where it just clamps the cigarette to be clamped: each cigarette clamping block 5 moves to the position and just clamps the cigarette to be clamped), the resistance of each cigarette clamping block 5 increases, which increases the current in the coil winding 2. After the controller that controls the coil winding 2 detects the signal of increased coil current, the controller continuously sends a locking current to the coil, and the coil continuously flows a stable locking current, which stabilizes the magnetic field generated by the coil. Under the action of the stable magnetic field, the rotating magnetic ring 3 causes each cigarette clamping block 5 to maintain a certain clamping torque, clamping the cigarette to be tested that has been placed in the cigarette clamping space 21. The computer and controller are existing technologies and have not been improved or designed, so their structure is not described in detail.

[0054] If it is necessary to drive the rotating magnetic ring 3 to release the cigarette clamping block 5 from the cigarette, a zero signal can be sent to the controller via the computer. The controller that controls the coil winding 2 to be energized will then reverse the coil. The reverse-energized coil will generate a magnetic field that drives the rotating magnetic ring 3 to release the cigarette clamping block 5 from the cigarette. Under the action of this magnetic field, the rotating magnetic ring 5 will drive each cigarette clamping block 5 connected to the rotating magnetic ring 5 to rotate to the fully open position (fully open position: the position where each cigarette clamping block does not clamp the cigarette). Then the three cigarette clamping blocks 5 will release the cigarette that was previously clamped.

[0055] It should be noted that the silicon steel sheet frame 11 includes components connected to the inner wall of the cylinder 9. The device consists of multiple connecting strips and multiple connecting blocks with six through slots (connecting blocks are rectangular blocks); the first end of each connecting strip is connected to the cylinder body, and the second end of each connecting strip is connected to the side wall of the connecting block with six through slots. Each copper wire is wound around the six through slots on each connecting block, so that each connecting block is wound with copper wire. Each connecting block with copper wire is arranged in a ring along the inner wall of the cylinder body 9. The connecting blocks can be magnets composed of multiple layers of silicon steel sheets with grooves connected in sequence.

[0056] It should be noted that by continuously switching the power supply on and off in the coil winding 2 and changing the polarity of the power source in a regular manner, the essence is to change the magnetic field strength and polarity of the coil winding 2, thereby causing the rotating magnetic ring 3 to rotate in a preset direction.

[0057] Please see Figure 6 The rotating magnetic ring 3, used to drive the cigarette clamping block 5 to clamp the cigarette to be clamped or to drive the cigarette clamping block 5 to release the cigarette to be clamped, includes a first magnetic ring 12, a second magnetic ring 13, and a magnetic ring cylinder 14; the first magnetic ring 12 and the second magnetic ring 13 are used to generate magnetism; the magnetic ring cylinder 14 is used as a base for mounting the first magnetic ring 12 and the second magnetic ring 13.

[0058] Specifically, the first magnetic ring 12 is located between the magnetic ring cylinder 14 and the copper wire, and the second magnetic ring 13 is also located between the magnetic ring cylinder 14 and the copper wire. Both the second magnetic ring 13 and the first magnetic ring 12 are sleeved on the magnetic ring cylinder 14. The first magnetic ring 12 and the second magnetic ring 13 are arranged from top to bottom along the outer wall of the magnetic ring cylinder 14. A certain gap can be left between the first magnetic ring 12 and the second magnetic ring 13 to distinguish them. The first magnetic ring 12 and the second magnetic ring 13 can be strong magnetic rings.

[0059] Please see Figure 7 and Figure 6 To enable the rotating magnetic ring 3 to be rotatably connected to the cigarette holder ring 4, the rotating magnetic ring 3 also includes a first annular step 15. The first annular step 15 is respectively opened at the open ends of the magnetic ring cylinder 14. The two first annular steps 15 are respectively fitted inside the outer ring of the bearing 16. The inner rings of the two bearings 16 are respectively fitted outside the outer walls near the two ends of the cigarette holder ring 4. The two ends of the cigarette holder ring 4 are respectively fixedly connected to the inner walls of the end caps 8.

[0060] In practical applications, since the first annular steps 15 are respectively opened at the open ends of the magnetic ring cylinder 14, the two first annular steps 15 are respectively fitted inside the outer ring of the bearing 16, and the inner rings of the two bearings 16 are respectively fitted outside the outer walls near the two ends of the cigarette holder ring 4. The two ends of the cigarette holder ring 4 are respectively fixedly connected to the inner walls of the two end caps 8, so the rotating magnetic ring 3 can rotate around the cigarette holder ring 4 fixedly connected to the housing 1.

[0061] Please see Figure 9 and Figure 10 To achieve the function of fixing the cigarette holder ring 4 to the housing 1, a second annular step 17 is provided on the inner wall of the end cover 8. The second annular step 17 is connected to the through hole 24 on the end cover 8. The through hole 24 is connected to both ends of the cigarette holder ring 4. The axis of the through hole 24 is on the same horizontal line as the axis of the cigarette holder ring 4. The second annular step 17 is an annular groove. The end of the annular groove facing the cigarette insertion area 7 is connected to the through hole 24.

[0062] In practical applications, since the through holes 24 are connected to both ends of the cigarette holder ring 4, and the axis of the through holes 24 is on the same horizontal line as the axis of the cigarette holder ring 4, and the end caps 8 are fixedly connected to the cylinder in the shell 1, the cigarette holder ring 4 is fixedly connected to the shell 1.

[0063] It should be noted that you should refer to [link / reference]. Figure 10 and Figure 7 To facilitate the assembly of bearing 6, the second annular step 17 corresponds to the first annular step 15. The second annular step 17 and the first annular step 15 together define a space for assembling bearing 16. This space is a complete annular space that matches the contour of bearing 16.

[0064] Please see Figure 11 , Figure 12 and Figure 13 To facilitate the assembly of the cigarette holder 5 and the rotating magnetic ring 3 onto the inner wall of the rotating magnetic ring 3, the rotating magnetic ring 3 also includes an arc-shaped groove 19. The arc-shaped groove 19 is located on the inner wall of the magnetic ring cylinder 14 between the two first annular steps 15. Three arc-shaped grooves 19 are spaced annularly along the inner wall of the magnetic ring cylinder 14. One end of each cigarette holder 5 is rotatably connected to each arc-shaped groove 19, and each cigarette holder 5 is fixedly connected to a connecting shaft 20 within each guide slot 6. The two ends of each cigarette clamping block 5 are rotatably connected, with the other end extending from each guide slot 6 on the side wall of the cigarette receiving ring 4 into the cigarette placement area 7 defined by the cigarette receiving ring 4. The three cigarette clamping blocks 5 define a space 3 21 for clamping cigarettes. The guide slot 6 is a through slot with two openings. The first opening faces the space 3 21 and communicates with it, and the second opening faces the inner wall of the rotating magnetic ring 3. The cigarette clamping block 5 can be a strip structure.

[0065] In practical applications, during the process of the rotating magnetic ring 3 driving the cigarette clamping block 5 to clamp the cigarette to be clamped, the rotating magnetic ring 3 will be linked with each cigarette clamping block 5 that is rotatably connected to the inner wall of the rotating magnetic ring 3 to rotate around the connecting shaft 20 in the guide slot 6 of the cigarette receiving ring 4. As each cigarette clamping block 5 rotates around the connecting shaft 20 in the guide slot 6, each rotating cigarette clamping block 5 located in the space 3 21 will move towards the space 3 21 to form a clamping area for the cigarette to be clamped, so as to clamp the cigarette to be clamped.

[0066] During the process of the rotating magnetic ring 3 driving the cigarette clamping block 5 to release the cigarette to be clamped, the rotating magnetic ring 3 will be linked with each cigarette clamping block 5 rotatably connected to the inner wall of the rotating magnetic ring 3 to rotate around the connecting shaft 20 in the guide slot 6 of the cigarette receiving ring 4. As each cigarette clamping block 5 rotates around the connecting shaft 20 in the guide slot 6, each rotating cigarette clamping block 5 located in the space 3 21 will disperse and move towards the space 3 21 to form a release area for the cigarette to be clamped, so as to release the pre-clamped cigarette.

[0067] It should be noted that the first annular step 15 is an annular groove, and the end of the annular groove facing the cigarette insertion area 7 is connected to the cigarette insertion area 7.

[0068] It should be noted that each cigarette holder 5 is rotatably connected to a connecting shaft 20 fixedly connected to each guide groove 6. That is, a connecting shaft 20 is vertically fixed between the inner walls of each guide groove 6 (see [link]). Figure 13 The connecting shaft is rotatably connected to the cigarette holder 5; in addition, each cigarette holder 5 passes through each guide slot 6.

[0069] It should be noted that although one end of each cigarette holder 5 is rotatably connected to each arc groove 19, the rotation between each cigarette holder 5 and each arc groove 19 is not significant.

[0070] Please see Figure 13 and Figure 14 A precision cigarette clamping device based on electromagnetic pulse drive also includes a rotating magnetic ring rotation limiting block 22. The rotating magnetic ring rotation limiting block 22 is connected to the inner wall of the groove on the outer wall of the cigarette receiving ring 4. The magnetic ring rotation limiting block 22 is in contact with the limiting groove 23 for limiting. The limiting groove 23 is opened on the first annular step 15 platform on the magnetic ring cylinder 14. The end of the limiting groove 23 near the cigarette receiving ring 4 is open. The limiting groove 23 has a rectangular structure.

[0071] In practical applications, during the process of the rotating magnetic ring 3 driving the cigarette clamping block 5 inside the cigarette receiving ring 4 to clamp the cigarette, the rotating magnetic ring rotation limiting block 22 on the outer wall of the rotating magnetic ring 3 will move and abut against the limiting groove 23 on the first annular step 15 platform of the magnetic ring cylinder 14 to limit the rotation of the rotating magnetic ring 3 within a certain range, thereby controlling the rotation of the rotating magnetic ring 3 to avoid excessive interference between the cigarette clamping block 5 connected to the inner wall of the rotating magnetic ring 3 and the rotating magnetic ring 3 and the cigarette receiving ring 4.

[0072] It should be noted that the height of the rotating magnetic ring body rotation limiting block 22 is lower than the groove depth of the limiting groove 23. This way, when the bearing 16 is placed in the first annular step 15, the placement of the shaft side 16 will not be affected by the rotating magnetic ring body rotation limiting block 22 protruding from the groove surface of the first annular step 15.

[0073] This application presents a precision cigarette clamping device based on electromagnetic pulse drive, comprising a housing 1, a coil winding 2, a rotating magnetic ring 3, a cigarette receiving ring 4, and a cigarette clamping block 5. This electromagnetic pulse-driven precision cigarette clamping device can not only clamp cigarettes of different specifications but also achieves high clamping and positioning accuracy, thus solving the problems of existing cigarette clamping devices that cannot automatically adjust according to cigarette specifications and have low clamping accuracy.
