Description

Technical Field

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

[0002] During the transportation, storage, and sales of products, a protective packaging layer, such as pearl cotton, is usually needed to protect the products from damage and improve their safety during distribution. Currently, in the product manufacturing and packaging process, pearl cotton and other packaging materials need to be cut to fit products of different sizes and with different protection requirements.

[0003] Existing cutting equipment includes a frame, a guiding mechanism, and a cutting mechanism. The guiding mechanism consists of a driver and rollers, which are fixed to the frame. Packaging materials such as pearl cotton are the parts to be cut. The parts are placed on the frame base plate. The driver drives the rollers to rotate, pulling the parts along the frame base plate to the cutting mechanism. The cutting mechanism cuts the parts to obtain parts that meet dimensional requirements. However, because the rollers are fixed in position, when the parts are thin, the rollers cannot contact them, preventing them from moving forward. When the parts are thick, they cannot be placed between the rollers and the frame base plate. Therefore, existing cutting equipment is not suitable for parts of different thicknesses.

[0063] The present invention proposes a cutting device 100.

[0064] Reference Figures 1 to 10 In some embodiments of the cutting device 100 of the present invention, the cutting device 100 includes a body 1, a guide mechanism 3, and a drive mechanism 2. The body 1 is provided with a support platform 11 for carrying the workpiece 6 to be cut. The guide mechanism 3 is used to drive the workpiece 6 to be cut to move along the support platform 11. The drive mechanism 2 is used to drive the guide mechanism 3 to move closer to or away from the support platform 11. The drive mechanism 2 is mounted on the body 1, and the guide mechanism 3 is connected to the drive mechanism 2. Exemplarily, the movement mode in which the guide mechanism 3 drives the workpiece 6 to move along the support platform 11 is not limited. The force applied by the guide mechanism 3 to the workpiece 6 can be a contact force, such as pressure, pushing force, pulling force, friction force, etc., or it can be a non-contact force, such as magnetic force, etc. The drive mechanism 2 can drive the guide mechanism 3 to approach and contact the workpiece 6, or it can drive the guide mechanism 3 to approach but not contact the workpiece 6. For example, the body 1 includes a base plate and two side plates disposed on both sides of the base plate. The base plate is a support platform 11 for supporting the workpiece 6 to be cut, and the upper surface of the base plate is the support surface. For example, the workpiece 6 to be cut can be packaging materials such as pearl cotton.

[0065] In the technical solution provided by this invention, the cutting device 100 includes a body 1, a guiding mechanism 3, and a driving mechanism 2. The body 1 is provided with a support platform 11, which supports the workpiece 6 to be cut, making the movement of the workpiece 6 more stable. The guiding mechanism 3 is used to drive the workpiece 6 to move along the support platform 11, guiding the workpiece 6 to different workstations. The driving mechanism 2 is used to drive the guiding mechanism 3 closer to or further away from the support platform 11. When the workpiece 6 to be cut is thin, the driving mechanism... Drive mechanism 2 can drive guide mechanism 3 to move closer to support platform 11, thereby reducing the distance between guide mechanism 3 and support platform 11, allowing guide mechanism 3 to guide thinner workpieces 6. When workpiece 6 is thicker, drive mechanism 2 can drive guide mechanism 3 to move away from support platform 11, thereby increasing the distance between guide mechanism 3 and support platform 11, allowing guide mechanism 3 to guide thicker workpieces 6. With this structure, by adjusting the distance between guide mechanism 3 and support platform 11 through drive mechanism 2, guide mechanism 3 can guide workpieces 6 of different thicknesses, thus making the cutting device 100 suitable for workpieces 6 of different thicknesses.

[0066] Specifically, in one embodiment, please refer to Figures 1 to 6 The guiding mechanism 3 applies a contact force to the workpiece 6 to be cut. The driving mechanism 2 includes a first driving component 21 and a driving member 22, and the guiding mechanism 3 includes a second driving component 31 and a guiding member 32. The driving member 22 is connected to either the second driving component 31 or the guiding member 32. The first driving component 21 drives the driving member 22 to move, causing the guiding member 32 to move closer to or further away from the support platform 11. The second driving component 31 drives the guiding member 32 to move, and the guiding member 32 contacts and drives the workpiece 6 to move along the support platform 11. For example, the first driving component 21 can be a linear driving component, such as an electric push rod. The contact force applied by the guiding mechanism 3 to the workpiece 6 can be a pushing force, a pulling force, or a frictional force. The guiding mechanism 3 can be a pushing mechanism for applying a pushing force to the workpiece 6, a pulling mechanism for applying a pulling force to the workpiece 6, or a frictional driving mechanism that uses the frictional force between the workpiece 6 and the guiding member 32 to drive the workpiece 6 to move. With this structure, the guide 32 contacts the workpiece 6 to be cut, and the second drive assembly 31 drives the guide 32 to move in order to apply force to the workpiece 6, so that the guide mechanism 3 can drive the workpiece 6 to move along the support platform 11; the first drive assembly 21 and the drive member 22 drive the guide assembly to move closer to or away from the support platform 11, so that the drive mechanism 2 can drive the guide 32 to contact or move away from the workpiece 6 to be cut, making it easy for the cutting device 100 to be suitable for workpieces 6 of different thicknesses.

[0067] Please see Figure 4 and Figure 5 Furthermore, the machine body 1 is provided with a first limiting groove 13, the driving member 22 is located in the limiting groove, the bearing platform 11 has a bearing surface, the driving member 22 moves relative to the first limiting groove 13 in the direction perpendicular to the bearing surface, and the driving member 22 and the first limiting groove 13 are mutually limited in the direction parallel to the bearing surface. The machine body 1 includes a base plate and two side plates on both sides of the base plate. The base plate is the bearing platform 11 used to support the workpiece 6 to be cut, and the upper surface of the base plate is the bearing surface. In this embodiment, the base plate is horizontally arranged, the direction perpendicular to the bearing surface is the vertical direction, and the direction parallel to the bearing surface is the horizontal direction. For example, the side plates of the machine body 1 have a first limiting groove 13 inside, and the driving member 22 is a block structure located within the first limiting groove 13. By adopting this structure, the first limiting groove 13 limits the drive component 22, which can improve the stability of the movement of the drive component 22, making the drive mechanism 2 drive the guide mechanism 3 to move more stably, thereby improving the overall stability of the cutting device 100.

[0068] Please see Figure 4 and Figure 5 Furthermore, the body 1 is also provided with a second limiting groove 14, and the driving member 22 is provided with a limiting rod 221 at least partially located in the second limiting groove 14. The limiting rod 221 moves relative to the second limiting groove 14 in a direction perpendicular to the bearing surface, and the limiting rod 221 and the second limiting groove 14 limit each other in a direction parallel to the bearing surface. A first spring 222 is sleeved on the outer periphery of the limiting rod 221. When the limiting rod 221 moves relative to the second limiting groove 14, the first spring 222 is compressed or released. For example, a limiting rod 221 is provided on each of the opposite sides of the driving member 22, and a first spring 222 is sleeved on each limiting rod 221. A protrusion extends from each of the opposite sides of the driving member 22. One end of the limiting rod 221 is connected to the protrusion, and the other end extends vertically into the second limiting groove 14. The first spring 222 is limited between the protrusion and the second limiting groove 14. With this structure, the limiting rod 221 and the second limiting groove 14 mutually limit each other, which can further improve the stability of the movement of the driving member 22. When the driving member 22 moves downward, it compresses the first spring 222. The elastic force applied by the first spring 222 to the driving member 22 can prevent the driving mechanism 2 from shaking, and further improve the overall stability of the driving mechanism 2.

[0069] Specifically, when the force applied by the guide mechanism 3 to the workpiece 6 is a contact force, the specific structure of the guide mechanism 3 can be implemented in the following two ways:

[0070] Implementation Method 1: The second driving component 31 is a rotary driving component, which drives the guide 32 to rotate. When the guide 32 rotates, it presses against the workpiece 6 to be cut and applies a force to the workpiece 6, thereby causing the workpiece 6 to move along a first direction. For example, the machine body 1 has an inlet end and an outlet end. The workpiece 6 moves from the inlet end to the support platform 11 of the machine body 1 and leaves the support platform 11 of the machine body 1 from the outlet end. The first direction is the direction extending from the inlet end to the outlet end of the machine body 1. The machine body 1 has a cutting station. The guide mechanism 3 can drive the workpiece 6 to move towards the cutting station, or it can drive the workpiece 6 into or out of the support platform 11. Using this mechanism, the rotary driving component can drive the guide 32 to rotate, thereby causing the workpiece 6 to move along the support platform 11, allowing the workpiece 6 to move to different stations.

[0071] Please see Figures 1 to 3 , Figure 6 , Figures 8 to 10 In one embodiment, the second drive assembly 31 includes a driver 311 and a rotating rod 313. A guide member 32 is fixedly connected to the rotating rod 313. The driver 311 drives the rotating rod 313 to rotate. When the rotating rod 313 rotates, it drives the guide member 32 to rotate. When the guide member 32 rotates, it presses against the workpiece 6 to be cut and applies a force to the workpiece 6, thereby causing the workpiece 6 to move along a first direction. The driver 311 is fixed to the machine body 1. The drive member 22 is rotatably connected to the rotating rod 313. When the drive member 22 moves, it drives the rotating rod 313 to move closer to or away from the support platform 11. For example, the drive member 22 has a cylindrical structure and a through hole 223. The rotating rod 313 passes through the through hole 223 and is rotatable relative to the drive member 22. For example, the driver 311 can be a motor, cylinder, etc. With this structure, the drive mechanism 2 can use the rotating rod 313 to drive the guide 32 to move closer to or away from the support platform 11 to accommodate workpieces 6 of different thicknesses; the driver 311 can drive the guide 32 to rotate through the rotating rod 313, and when the guide 32 rotates, it can drive the workpiece 6 to move along the support platform 11, so that the workpiece 6 can move to the cutting station or move away from the support platform 11.

[0072] Further, please refer to Figures 1 to 4 , Figure 6 , Figures 8 to 10The rotating rod 313 has at least two, such as two, three, four, or five. The drive mechanism 2 also includes a connecting member 23. When the driver 311 is fixed to the body 1 and the driving member 22 is rotatably connected to the rotating rod 313, each end of a single rotating rod 313 is provided with a driving member 22. The two driving members 22, which are respectively connected to two adjacent rotating rods 313 and located on the same side, are connected by the connecting member 23. The first drive assembly 21 is connected to the connecting member 23 to simultaneously drive at least two driving members 22 to move. For example, there are two rotating rods 313 arranged in parallel. Each end of a single rotating rod 313 is rotatably connected to a driving member 22. The connecting member 23 is a plate-shaped structure. The two driving members 22 located on one side of the two rotating rods 313 are connected by the connecting member 23. The first drive assembly 21 is connected to the middle position of the connecting member 23. With this structure, the guides 32 on multiple rotating rods 313 drive the workpiece 6 to move, which can improve the stability of the movement of the workpiece 6 and facilitate the movement of the workpiece 6 to the designated position. Multiple rotating rods 313 can be driven to move simultaneously through a first drive assembly 21, which simplifies the structure of the drive mechanism 2 and improves the convenience and accuracy of position control of multiple rotating rods 313.

[0073] In another embodiment, the drive member 22 is fixedly connected to the driver 311. When the drive member 22 moves, it drives the second drive assembly 31 to move closer to or away from the support platform 11. With this structure, the guide mechanism 3 is mounted entirely on the drive member 22. The drive mechanism 2 can drive the entire guide mechanism 3 to move, thereby moving the guide member 32 closer to or away from the support platform 11, so that the cutting device 100 can adapt to the workpiece 6 of different thicknesses. The driver 311 in the guide mechanism 3 can drive the guide member 32 to rotate through the rotating rod 313. When the guide member 32 rotates, it can drive the workpiece 6 to move along the support platform 11, so that the workpiece 6 can move to the cutting station or move away from the support platform 11.

[0074] Furthermore, at least two rotating rods 313 are provided, such as two, three, four, five, etc. The drive mechanism 2 also includes a connecting member 23. When the drive member 22 is fixedly connected to the driver 311, the driver 311 is provided at least two and is respectively connected to at least two rotating rods 313. The drive member 22 is provided at least two and is respectively connected to at least two drivers 311. Adjacent drive members 22 are connected through the connecting member 23. The first drive assembly 21 is connected to the connecting member 23 to drive at least two drive members 22 to move simultaneously. With this structure, multiple actuators 311 drive multiple rotating rods 313 to rotate, and each rotating rod 313 drives its guide member 32 to rotate. The rotation of the guide member 32 can drive the workpiece 6 to move. By driving the workpiece 6 to move through the guide members 32 on the multiple rotating rods 313, the stability of the movement of the workpiece 6 can be improved, and it is convenient to guide the workpiece 6 to move to the designated position. A first drive assembly 21 can drive multiple actuators 311 and rotating rods 313 to move at the same time, which simplifies the structure of the drive mechanism 2 and improves the convenience and accuracy of position control of multiple rotating rods 313.

[0075] Please see Figure 1 , Figures 6 to 10Furthermore, the second drive assembly 31 also includes a transmission mechanism 312. The driver 311 is connected to the rotating rod 313 via the transmission mechanism 312. The transmission mechanism 312 can be any known mechanism capable of driving the rotating rod 313 to rotate, such as a gear transmission mechanism 312. As an example, the transmission mechanism 312 in this embodiment is a pulley transmission structure. When there are at least two rotating rods 313, the driver 311 is fixed on the body 1, and the drive member 22 is rotatably connected to the rotating rod 313, the pulley transmission structure includes a first pulley 3121, a conveyor belt 3122, and at least two second pulleys 3123. The first pulley 3121 is connected to the driver 311, and the at least two second pulleys 3123 are respectively connected to at least two rotating rods 313. The first pulley 3121 and the at least two second pulleys 3123 are connected via the conveyor belt 3122. During operation, the driver 311 drives the first pulley 3121 to rotate. The rotation of the first pulley drives at least two second pulleys 3123 to rotate via the conveyor belt 3122. The rotation of the at least two second pulleys 3123 respectively drives at least two rotating rods 313 to rotate. For example, there are two rotating rods 313 and two second pulleys 3123. Each end of a single rotating rod 313 is connected to a transmission mechanism 312 and a driver 311. For example, each end of a rotating rod 313 is provided with a set of drivers 311 and a transmission mechanism 312. With this structure, a single driver 311 can drive multiple rotating rods 313 to rotate, simplifying the overall structure of the guiding mechanism 3. At the same time, the flexibility of the conveyor belt 3122 can be utilized so that when the driving mechanism 2 moves the rotating rods 313 and the second pulley 3123 closer to or away from the support platform 11, the driver 311 can still use the first pulley 3121 and the conveyor belt 3122 to drive the second pulley 3123 to rotate, thereby driving the rotating rods 313 to rotate. This avoids the rotating rods 313 being unable to rotate during or after moving closer to or away from the support platform 11 in order to guide the movement of the workpiece 6 to be cut.

[0076] It should be noted that when the driver 311 of the guide mechanism 3 is fixed to the body 1, during the process of the drive mechanism 2 driving the rotating rod 313 to move closer to or away from the support platform 11, the driver 311 in the guide mechanism 3 is fixed, while the rotating rod 313 is movable; when the driver 311 and the rotating rod 313 are connected through the aforementioned transmission mechanism 312, since the first pulley 3121 is connected to the driver 311, the position of the first pulley 3121 is fixed, and since the second pulley 3123 is connected to the rotating rod 313, the second pulley 3123 will move together with the rotating rod 313. Therefore, when the drive mechanism 2 drives the rotating rod 313 to move closer to or away from the support platform 11, the position of the first pulley 3121 is relatively fixed relative to the driver 311, and the position of the second pulley 3123 moves together with the rotating rod 313. Furthermore, when there are at least two rotating rods 313, the drive mechanism 2 simultaneously drives at least two rotating rods 313 to move closer to or away from the support platform 11, thereby simultaneously driving at least two second pulleys 3123 connected to the rotating rods 313 to move. At this time, due to the second pulley 312... When the movement moves closer to or away from the support platform 11, the distance between the pulley 3121 and the first pulley 3121 will decrease or increase. However, the distance between two adjacent second pulleys 3123 is fixed. Therefore, during the movement of the second pulley 3123 closer to or away from the support platform 11, the conveyor belt 3122 that transmits power between the first pulley 3121 and the second pulley 3123 may become loose or excessively tense, which will affect the transmission between the first pulley 3121 and the second pulley 3123, and thus affect the rotation of the rotating rod 313.

[0077] To resolve the above issues, please refer to [link / reference]. Figure 1 , Figures 6 to 10Furthermore, in this embodiment, the second drive assembly 31 also includes a belt actuator 314, which includes a movable rod 3141 and an upper limit member 3142 and a lower limit member 3143 respectively connected to the movable rod 3141. The transmission belt is located between the upper limit member 3142 and the lower limit member 3143. The drive mechanism 2 also includes an extension rod 24 connected to the first drive assembly 21. A connecting air groove 12 is provided inside the body 1. The movable rod 3141 is located at one end of the connecting air groove 12, and the extension rod 24 is located at the other end of the connecting air groove 12. The first drive assembly 21 drives the extension rod 24 to move. When the extension rod 24 moves, it squeezes the air in the connecting air groove 12 to drive the movable rod 3141 to move. Preferably, the upper limit member 3142 and the lower limit member 3143 are both wheel structures. For example, the actuator 314 further includes two vertical rods and two horizontal rods. The two horizontal rods are arranged in parallel and their ends are respectively connected to the two vertical rods. The first limiting member and the second limiting member are rotatably connected to the two horizontal rods. One end of the movable rod 3141 is a tubular structure sleeved on the outside of one of the vertical rods. For example, the openings at both ends of the connecting air groove 12 face the same direction, the movement direction of the extension rod 24 is opposite to the movement direction of the movable rod 3141, and the connecting air groove 12 is a U-shaped groove. With this structure, when the drive mechanism 2 drives the rotating rod 313 to approach the support platform 11, the rotating rod 313 drives the second pulley 3123 to move towards the first pulley 3121, reducing the distance between the second pulley 3123 and the first pulley 3121. At this time, the extension rod 24 of the drive mechanism 2 can compress the air in the communicating air groove 12 to drive the movable rod 3141 to move away from the support platform 11, thereby driving the conveyor belt 3122 to move away from the support platform 11 through the lower limit member 3143, so that the conveyor belt 3122 can be kept taut and prevent the conveyor belt 3122 from slackening and falling off; when the drive mechanism 2 drives the rotating rod 3123 to approach the support platform 11, the extension rod 3123 drives the second pulley 3123 to move towards the first pulley 3121, reducing the distance between the second pulley 3123 and the first pulley 3121. When the moving rod 313 moves away from the support platform 11, the rotating rod 313 drives the second pulley 3123 to move away from the first pulley 3121, increasing the distance between the second pulley 3123 and the first pulley 3121. At this time, the extension rod 24 of the drive mechanism 2 can draw air from the air groove 12 to drive the moving rod 3141 to move towards the support platform 11, and then drive the conveyor belt 3122 to move towards the support platform 11 through the upper limit member 3142, so that the conveyor belt 3122 can be appropriately relaxed, avoiding excessive tension of the conveyor belt 3122, thereby improving the reliability of the connection between the first pulley 3121 and the second pulley 3123. In addition, when both the upper limit member 3142 and the lower limit member 3143 are wheel structures, the friction between the upper limit member 3142 and the conveyor belt 3122 is rolling friction, and the friction between the lower limit member 3143 and the conveyor belt 3122 is rolling friction, which reduces the wear of the conveyor belt 3122 and reduces the influence of the upper limit member 3142 and the lower limit member 3143 on the movement of the conveyor belt 3122.

[0078] Please see Figures 1 to 3 , Figure 6 , Figures 8 to 10 Furthermore, the guide member 32 includes a ring 321, a second spring 323, and a pressure block 324. The ring 321 is sleeved on the rotating rod 313, and the pressure block 324 is connected to the ring 321 via the second spring 323. When the guide member 32 rotates, it drives the pressure block 324 to press against the workpiece 6 to be cut and apply force to the workpiece 6 to move it along the first direction. When the pressure block 324 presses against the workpiece 6, it compresses the second spring 323. Preferably, the rotating rod 313 is provided with at least two guide members 32, and / or the ring 321 is connected with at least two pressure blocks 324. For example, the central hole of the ring 321 is interference-fitted with the rotating rod 313, and the two ends of the second spring 323 are fixedly connected to the ring 321 and the pressure block 324, respectively. With this structure, when the guide 32 rotates and presses against the workpiece 6 to be cut, the pressure block 324 contacts the workpiece 6 to be cut and compresses the second spring 323. Through the elastic action of the second spring 323, the pressure applied by the pressure block 324 to the workpiece 6 to be cut can be increased, thereby improving the stability of the guide 32 in pulling the workpiece 6 to be cut. At the same time, by utilizing the elastic force applied by the second spring 323 to the pressure block 324, the pressure block 324 can apply a forward pushing force to the workpiece 6 to be cut, making it easier for the workpiece 6 to be cut to move to different work positions.

[0079] Please see Figure 2 , Figure 3 and Figure 6 Furthermore, the ring 321 is provided with a positioning tube 322, and the pressure block 324 includes a positioning part and a pressing part. The positioning part is at least partially located inside the positioning tube 322 and mutually limits the positioning tube 322. The pressing part has an arc-shaped structure, and the second spring 323 is located inside the positioning tube 322. For example, a positioning tube 322, the second spring 323, and the pressure block 324 form a set of pressing structures. Four sets of pressing structures are evenly provided on the ring 321 along its circumferential direction, and a rotating rod 313 is provided with two guide members 32. With this structure, the positioning part of the pressure block 324 mutually limits the positioning tube 322, and the positioning tube 322 limits the second spring 323, which can improve the stability of the movement of the pressure block 324 and prevent the pressure block 324 from moving off course. When the pressing part has an arc-shaped structure, it can prevent the pressure block 324 from pressing the workpiece 6 and causing damage to it when it has a sharp corner structure.

[0080] In addition, the guide 32 can also be a roller structure. When the roller structure rotates, the friction between it and the workpiece 6 to be cut can drive the workpiece 6 to move along the support platform 11. The second drive component 31 drives the roller to rotate, and the drive mechanism 2 drives the roller structure to move closer to or away from the support platform 11.

[0081] Implementation Method 2: The second driving component 31 is a linear driving component. This component drives the guide 32 to perform linear motion. The guide 32 is in frictional contact with the workpiece 6 to be cut. When the guide 32 moves, it utilizes the static friction between itself and the workpiece 6 to drive the workpiece 6 to move along a first direction. For example, the guide 32 is a plate. The plate contacts the workpiece 6 to be cut and uses friction for transmission. The linear driving component drives the plate to perform linear motion, thereby driving the workpiece 6 to perform linear motion.

[0082] Please see Figure 1 , Figure 4 , Figures 7 to 10 Furthermore, the first drive assembly 21 includes a threaded connector 211. The machine body 1 has a threaded hole that engages with the threaded connector 211. The drive component 22 is connected to the threaded connector 211. When the threaded connector 211 is screwed relative to the machine body 1, it drives the drive component 22 to move. For example, the first drive assembly 21 is a bolt, which engages with the threaded hole on the machine body 1, and one end of the bolt is rotatably connected to the connector 23. For example, there are two first drive assemblies 21, each located on one of the two side plates of the machine body 1, and each side plate has a threaded hole. With this structure, the drive component 22 can be moved closer to or away from the support platform 11 by screwing the bolt, thereby moving the guide component 32 in the guide mechanism 3 closer to or away from the support platform 11 to accommodate workpieces 6 of different thicknesses. This drive assembly has a simple structure and is easy to install and process. Alternatively, the first drive assembly 21 can also be a linear drive assembly, a gripping mechanism, or other structures.

[0083] Please see Figures 1 to 4 , Figures 8 to 10 Furthermore, the cutting device 100 also includes a cutting mechanism 4 for cutting the workpiece 6 to be cut. The cutting mechanism 4 includes a third drive assembly 41, a cutter 43, and a guide rail 42. The guide rail 42 is mounted on the machine body 1, and the cutter 43 is slidably connected to the guide rail 42. The third drive assembly 41 drives the cutter 43 to move along the length of the guide rail 42 to cut the workpiece 6 to be cut. For example, the cutter 43 has a through hole, and the guide rail 42 is inserted into the through hole. The guide rail 42 is a long strip structure, and its two ends are respectively fixed to the two side plates of the machine body 1. With this structure, the third drive assembly 41 can drive the cutter 43 to move along the guide rail 42 to cut the workpiece 6 to be cut, thereby obtaining a workpiece 6 that meets the size requirements. At this time, the thickness of the workpiece 6 can be disregarded when cutting it by cutting. It is only necessary to ensure that the blade height of the cutter 43 is greater than the thickness of the workpiece 6. Of course, the position of the cutter 43 can also be adjusted. The cutting mechanism 4 can include a fourth driving component for driving the cutting mechanism 4 closer to or away from the workpiece 6. By driving the cutter 43 closer to or away from the workpiece 6 through the fourth driving component, workpieces 6 of different thicknesses can be cut.

[0084] For example, when there are at least two rotating rods 313, the cutter 43 is located between at least two rotating rods 313. With this structure, firstly, the guides 32 on both sides of the cutter 43 can be used to press the workpiece 6 to be cut, so as to prevent the workpiece 6 to be cut from shifting when the cutter 43 moves, thus affecting the cutting effect. Secondly, the cutter 43 cuts the workpiece 6 into two independent cut pieces, and the two cut pieces can be driven by the guides 32 on both sides of the cutter 43 respectively, so as to prevent the workpiece 6 from being unable or inconvenient to move to other workstations after cutting.

[0085] Please see Figures 1 to 4 , Figures 8 to 10 Furthermore, the third drive assembly 41 includes a drive body 411 and a telescopic rod 412. The drive body 411 is fixed to the machine body 1. The two ends of the telescopic rod 412 are respectively connected to the cutter 43 and the drive body 411. The cutter 43 is rotatably connected to the telescopic rod 412. The drive body 411 is used to drive the telescopic rod 412 to rotate. When the telescopic rod 412 rotates, it extends and retracts, driving the cutter 43 to move along the guide rail 42 to cut the workpiece 6. For example, the telescopic rod 412 includes an outer tube 4121 and an inner rod 4122 that are nested together. The inner rod 4122 is rotatably connected to the cutter 43, and the outer tube 4121 is connected to the drive body 411. For example, the machine body 1 also includes a top plate, the two ends of which are respectively connected to the top of two side plates. The drive body 411 is mounted on the top plate. For example, the drive body 411 can be a motor, cylinder, etc. With this structure, the drive body 411 can swing the telescopic rod 412 to drive the cutter 43 to move along the guide rail 42, thereby realizing the cutting action of the cutting mechanism 4.

[0086] In some embodiments, the cutting device 100 is applied in the field of packaging equipment technology to cut packaged products, such as cutting pearl cotton.

[0087] Please see Figures 1 to 4 , Figures 8 to 10 Furthermore, the cutting device 100 is used for cutting pearl cotton, and the cutting device 100 also includes a guide roller 5 for flattening the pearl cotton. For example, the two side plates of the machine body 1 are respectively provided with U-shaped holes facing the same direction, and the guide roller 5 has rotating shafts at both ends, which are placed inside the U-shaped holes. In addition, pearl cotton can be sleeved on the outside of the guide roller 5; utilizing the elasticity of the pearl cotton itself, the flattening effect of the guide roller 5 can be improved. With this structure, when the pearl cotton enters the cutting device 100, it is first flattened by the guide roller 5, preventing the pearl cotton from being difficult to move using the guiding mechanism 3 when it is curled; furthermore, the guide roller 5 can move within the U-shaped hole to accommodate pieces 6 of different thicknesses to be cut.

[0088] As an example, there are two rotating rods 313, which are the first rotating rod 313 and the second rotating rod 313 in sequence along the direction in which the workpiece 6 is fed into the machine body 1. The workpiece 6 is pearl cotton. The cutting steps of the cutting device 100 in this embodiment are as follows:

[0089] First, the staff places one end of the pearl cotton on the support platform 11 and moves it towards the inside of the machine body 1. The guide roller 5 is used to spread the pearl cotton, so that one end of the pearl cotton moves between the first rotating rod 313 and the support platform 11.

[0090] Secondly, depending on the thickness of the pearl cotton, the threaded connector 211 is screwed on to drive the drive member 22 to move toward or away from the support platform 11, thereby adjusting the positions of the first rotating rod 313 and the second rotating rod 313 until the guide member 32 on the first rotating rod 313 can press against the pearl cotton. At this time, the first pulley 3121 is driven to rotate by the driver 311. The first pulley 3121 drives the two second pulleys 3123 to rotate in sequence through the conveyor belt 3122, thereby driving the first rotating rod 313 and the second rotating rod 313 to rotate. When the first rotating rod 313 rotates, it drives the guide member 32 on it to rotate to guide the pearl cotton to move forward. When the pearl cotton contacts the guide member 32 on the second rotating rod 313, the guide member 32 on the second rotating rod 313 rotates to further guide the pearl cotton to move forward until the pearl cotton moves to the designated cutting position.

[0091] Then, the telescopic rod 412 is driven to swing by the drive body 411. When the telescopic rod 412 swings, it drives the cutter 43 to move along the guide rail 42 to cut the pearl cotton, thus completing the cutting operation.

[0092] Finally, the first pulley 3121 is driven to rotate by the driver 311. The first pulley 3121 drives the two second pulleys 3123 to rotate in sequence via the conveyor belt 3122, which in turn drives the first rotating rod 313 and the second rotating rod 313 to rotate. When the second rotating rod 313 rotates, it drives the guide 32 on it to rotate to guide the cut pearl cotton away from the carrying platform 11. When the first rotating rod 313 rotates, it drives the guide 32 on it to rotate to guide the uncut pearl cotton to the next cutting operation.
