Description

Technical Field

[0001] This application relates to the field of packaging machinery technology, specifically to a bag-feeding machine. Background Technology

[0002] Packaging machines, widely used automated equipment in the food, pharmaceutical, and daily necessities industries, primarily function to precisely cut connected strips of packaging bags and accurately place the individual bags onto designated target items, such as seasoning packets in instant noodles, or desiccant and preservative packets in pharmaceutical or food packaging. The widespread application of this equipment significantly improves production efficiency and packaging quality.

[0003] In its patent application with publication number CN109733697A, the applicant details a technical solution for a high-speed bag-feeding machine. This high-speed bag-feeding machine includes a stable frame, on which are sequentially arranged a bag belt intermediate pool, a conveyor roller assembly, a precise tension control assembly, a reliable traction assembly, a high-efficiency cutting assembly, and a precise bag-feeding assembly. A target material conveyor belt is located at the lower part of the frame, and the frame also includes an inclined bag-feeding channel arranged from high to low along the conveying direction of the target material conveyor belt, ensuring smooth bag flow. The traction assembly, cutting assembly, and bag-feeding assembly are arranged sequentially from high to low on the bag-feeding channel, optimizing the bag-feeding process.

[0004] Specifically, the cutting assembly includes a rotary cutting frame mounted on a main frame. The rotary cutting frame has mutually compatible driving and driven rotary rollers mounted on it via bearings. Both are driven by the same rotary roller drive motor to move in opposite directions, ensuring precise cutting. Each driving and driven rotary roller is equipped with at least one cutter, enabling fast and accurate bag feeding, neatly placing the bag onto the target material, greatly improving production efficiency. At the same time, the cutter replacement design is simple, reducing the failure rate and improving equipment reliability.

[0005] However, as can be seen from the aforementioned patent, although this high-speed baggage feeder has significant advantages in terms of accuracy and efficiency, reducing the labor intensity and labor costs for workers, it still has certain limitations in actual use. Specifically, the metal and rubber traction wheels in the traction assembly remain fixed after installation and are in close contact with the upper and lower sides of the baggage conveyor belt, respectively. When the baggage conveyor belt becomes stuck or blocked in the conveyor channel, this design makes it difficult for workers to remove the baggage conveyor belt for unblocking, complicating the operation, increasing the difficulty of work, and reducing the maintenance efficiency of the baggage feeder.

[0029] Beneficial effects:

[0030] 1. Through the above technical solution, in one aspect, the guide rail of this application is set in an inclined downward direction, which can make the strip bag of material pulled by the traction component to the cutting component form an inclined downward transportation direction. Compared with the horizontal transportation method in the prior art, the strip bag of material can have better support, which can also make it easier for the cutting component to cut the strip bag of material more effectively.

[0031] On the other hand, the guide rail includes a first rail body and a second rail body that are spaced apart from each other. This not only allows for good adaptation to the stable traction of strip-shaped material bags, but also facilitates the adjustment of the distance between the first rail body and the second rail body according to the width of the strip-shaped material bags, so as to be suitable for strip-shaped material bags of different widths.

[0032] On another note, the adjusting component of this application can quickly and stably separate the first traction wheel and the second traction wheel, that is, switch from the traction state to the maintenance state, so that the stuck or blocked strip-shaped material bags can be cleaned more quickly and conveniently. This not only effectively reduces the difficulty of unblocking the strip-shaped material bags, but also helps to effectively improve maintenance efficiency.

[0033] More importantly, the adjusting component of this application has a very small dimension in the width direction (only the width of the mounting frame needs to be considered; all other components are located within the mounting frame). Therefore, it can be installed at any position on the adjusting plate (except at the hinge between the adjusting plate and the frame), and can be well adapted to the traction assembly of compact baggage droppers. For example, see [reference needed]. Figure 3 , Figure 3 The adjusting component is installed in the middle of the adjusting plate. It can be seen that there are other structures or parts on its left, right and bottom. The adjusting component of this application has a very small installation space requirement and can be well adapted to the compact traction assembly.

[0056] The technical solution of this application will be described in detail below with reference to the accompanying drawings.

[0057] Example 1

[0058] like Figures 1 to 9 As shown, this embodiment provides a bag-feeding machine 100, including a frame 1, and a traction component 2 and a bag-cutting component 3 respectively installed on the frame 1. The traction component 2 is used to pull the strip-shaped material bag to the bag-cutting component 3, and the bag-cutting component 3 is used to cut the strip-shaped material bag at preset intervals.

[0059] The traction assembly 2 includes a guide rail 21, a first drive member 22, a first traction wheel 23, an adjusting plate 24, a second traction wheel 25, and an adjusting member 26. The guide rail 21 is mounted on the frame 1 in a downward inclined direction. The guide rail 21 is used to carry strip-shaped material bags and guide the strip-shaped material bags to the cutting assembly 3 in a downward inclined direction. The guide rail 21 includes a first rail body 211 and a second rail body 212 that are spaced apart from each other. The first rail body 211 and the second rail body 212 are used together to carry the strip-shaped material bags. The first traction wheel 23 is rotatably mounted on the frame 1 and is located between the first rail body 211 and the second rail body 212. One end of the adjusting plate 24 is rotatably mounted on the frame 1, and the second traction wheel 25 is rotatably mounted on the adjusting plate 24. The second traction wheel 25 is located above the first traction wheel 23 to jointly clamp and pull the strip-shaped material bags. The adjusting member 26 includes a mounting bracket 261. The machine comprises a support block 262, an operating handle 263, a first connecting rod 264, a second connecting rod 265, a third connecting rod 266, and a connecting rod 267. A mounting bracket 261 is mounted on the frame 1. The support block 262 is mounted on the mounting bracket 261. The operating handle 263 is located above the support block 262, with one end of the operating handle 263 near the support block 262 connected to the first connecting rod 264. The end of the first connecting rod 264 away from the operating handle 263 is rotatably mounted on the support block 262. At the bottom, a protrusion 2621 is formed on the side of the support block 262 away from the top of the frame 1. One end of the second connecting rod 265 is hinged to the middle of the first connecting rod 264, and the other end of the second connecting rod 265 is hinged to the third connecting rod 266. The second connecting rod 265 is located between the support block 262 and the operating handle 263 and abuts against the support block 262. The end of the third connecting rod 266 away from the second connecting rod 265 is connected to the connecting rod 267. The connecting rod 267 is connected to the adjusting plate 24.

[0060] Traction component 2 includes traction state (see reference) Figure 3 ) and maintenance status (see reference) Figure 4In the traction state, the second connecting rod 265 is separated from the protrusion 2621, the adjusting plate 24 extends in the same direction as the guide rail 21, and there is a first preset distance between the first traction wheel 23 and the second traction wheel 25 so that the first traction wheel 23 and the second traction wheel 25 can be used together to clamp and pull the strip-shaped material bag; in the maintenance state, the second connecting rod 265 abuts against the protrusion 2621, there is an angle between the extension direction of the adjusting plate 24 and the extension direction of the guide rail 21, and there is a second preset distance between the first traction wheel 23 and the second traction wheel 25 so that the strip-shaped material bag between the first traction wheel 23 and the second traction wheel 25 can be disassembled or cleaned.

[0061] Through the above technical solution, on the one hand, the guide rail 21 of this application is set in an inclined downward direction, so that the strip-shaped material bag pulled by the traction component 2 to the cutting component 3 forms an inclined downward transportation direction. Compared with the horizontal transportation method in the prior art, the strip-shaped material bag can have better support, which is more conducive to the cutting component 3 cutting the strip-shaped material bag more effectively.

[0062] On the other hand, the guide rail 21 includes a first rail body 211 and a second rail body 212 that are spaced apart from each other. It can not only be well adapted to the stable traction of the strip bag, but also facilitate the adjustment of the distance between the first rail body 211 and the second rail body 212 according to the width of the strip bag, so as to be suitable for strip bags of different widths.

[0063] On another note, the adjusting member 26 of this application can quickly and stably separate the first traction wheel 23 and the second traction wheel 25, that is, switch from the traction state to the maintenance state, so that the stuck or blocked strip-shaped material bags can be cleaned more quickly and conveniently. This not only effectively reduces the difficulty of unblocking the strip-shaped material bags, but also helps to effectively improve maintenance efficiency.

[0064] More importantly, the adjusting member 26 of this application has a very small dimension in the width direction (only the width dimension of the mounting bracket 261 needs to be considered, and all other components are located within the mounting bracket 261), so it can be installed at any position of the adjusting plate 24 (except at the hinge between the adjusting plate 24 and the frame 1), and can be well adapted to the traction assembly 2 of the compact baggage dropper 100. For example, see [reference needed]. Figure 3 , Figure 3 The adjusting component 26 is installed in the middle of the adjusting plate 24. It can be seen that there are other structures or components on its left, right and bottom. The adjusting component 26 of this application has a very small installation space requirement and can be well adapted to the compact traction assembly 2.

[0065] In this embodiment, it is understood that, firstly, the frame 1 of this application may also include, as in the applicant's prior patent application (CN109733697A), a material bag intermediate pool, a conveying roller assembly, a tension control assembly, and a bag conveying assembly, to complete the bag cutting operation more conveniently, accurately, and stably. Since the above structure has been disclosed in the prior patent application, it will not be described again in this application.

[0066] Second, to facilitate understanding by relevant technical personnel, the working process / working principle of the adjusting component 26 will be explained below.

[0067] Please see Figure 3 and Figure 4 When it is necessary to clear the strip-shaped material bags (for example, when the strip-shaped material bags are stuck or blocked), you can hold the operating handle 263 and turn it downwards away from the adjusting plate 24. The operating handle 263 drives the first connecting rod 264 to rotate around the bottom of the support block 262. The first connecting rod 264 drives the second connecting rod 265 to rotate. During the rotation, the second connecting rod 265 will abut against the protrusion 2621 on the support block 262, which will then drive the third connecting rod 266 to rotate around the support block 262. The end of the third connecting rod 266 away from the support block 262 will move upwards. The third connecting rod 266 will then drive the connecting rod 267 to move upwards. Since one end of the adjusting plate 24 is rotatably connected to the frame 1, the connecting rod 267 will drive the adjusting plate 24 connected to it to rotate upwards, which will in turn drive the second traction wheel 25 to move upwards and separate from the first traction wheel 23.

[0068] Third, in this application, the first traction wheel 23 is the driving wheel and the second traction wheel 25 is the driven wheel. The first traction wheel 23 is directly mounted on the frame 1 and the second traction wheel 25 is mounted on the adjustment plate 24. This is beneficial for arranging a corresponding drive device for the first traction wheel 23. At the same time, the second traction wheel 25 does not need to be equipped with a corresponding drive device, which can further effectively reduce the installation space requirement of the adjustment component 26.

[0069] Fourth, in the traction state, the first preset distance between the first traction wheel 23 and the second traction wheel 25 can be 0, that is, the first traction wheel 23 and the second traction wheel 25 abut against each other to jointly traction the strip-shaped material bag. The first preset distance between the first traction wheel 23 and the second traction wheel 25 can also be negative, that is, there is a certain degree of mutual compression between the first traction wheel 23 and the second traction wheel 25. For example, the first traction wheel 23 is made of flexible material to jointly traction the strip-shaped material bag. The first preset distance between the first traction wheel 23 and the second traction wheel 25 can also be slightly greater than 0, for example, 0.1mm-3.5mm, which can also achieve joint traction of the strip-shaped material bag. This application does not specifically limit the value of the first preset distance.

[0070] Fifth, in the maintenance state, the second preset distance between the first traction wheel 23 and the second traction wheel 25 should meet the needs of manual operation. For example, it can be set to 1cm-30cm to facilitate the operator to clean and unclog the stuck or blocked strip-shaped material bags. This application does not specify the value of the second preset distance, but it is understood that the second preset distance must be greater than the first preset distance.

[0071] In one embodiment of this application, such as Figures 3 to 5 As shown, the traction assembly 2 of this application may further include a drive motor 27, a first transmission rod 281, a second transmission rod 282, and a first gear 283 and a second gear 284 meshing with each other. The two ends of the first transmission rod 281 are respectively connected to the output end of the drive motor 27 and the first traction wheel 23. The first gear 283 is sleeved on the first transmission rod 281. The second transmission rod 282 is mounted on the adjusting plate 24. The second traction wheel 25 and the second gear 284 are respectively sleeved on the second transmission rod 282. The ratio of the number of first gears 283 to the number of second gears 284 is 1:1.

[0072] In this way, by configuring the drive motor 27, the first transmission rod 281, the second transmission rod 282, the first gear 283, and the second gear 284 as described, it is possible to effectively enable the drive motor 27 to synchronously drive the first traction wheel 23 and the second traction wheel 25 to rotate. This not only ensures the reliable traction of the first traction wheel 23 and the second traction wheel 25 for the strip-shaped material bag, but also effectively reduces the installation space requirement of the adjusting component 26 (compared to the solution that also requires the installation of a corresponding drive device for the second traction wheel 25).

[0073] In one embodiment of this application, such as Figures 3 to 5 As shown, the first transmission rod 281, second transmission rod 282, first gear 283, second gear 284, first traction wheel 23, and second traction wheel 25 of this application can each be configured as two, and are spaced apart along the extension direction of the guide rail 21. The two first transmission rods 281 are respectively connected to the drive motor 27 via a synchronous belt drive structure, so that the drive motor 27 can drive the two first transmission rods 281 to rotate synchronously. In this way, the first transmission rod 281, second transmission rod 282, first gear 283, second gear 284, first traction wheel 23, and second traction wheel 25 configured in this manner can more smoothly and reliably pull the strip-shaped material bag.

[0074] In one embodiment of this application, such as Figures 6 to 9As shown, the first link 264 of this application can be configured as two, with the two first links 264 arranged at intervals between each other. The first link 264 includes a first mounting plate 2641, a connecting plate 2642, a U-shaped plate 2643, and a second mounting plate 2644 connected in sequence. The first mounting plate 2641 is connected to the bottom of the operating handle 263. One end of the second link 265 is hinged to the connecting plate 2642. The U-shaped plate 2643 protrudes in a direction away from the second link 265. The second mounting plate 2644 is rotatably mounted on the bottom of the support block 262. The second link 265 and a portion of the third link 266 are located within the U-shaped plate 2643.

[0075] In this way, the two second links 265 can rotate more smoothly and reliably, thereby enabling the traction assembly 2 to switch from the traction state to the maintenance state more smoothly and reliably. In this embodiment, the first mounting plate 2641 is used to connect to the operating handle 263, the connecting plate 2642 is used to hinge the second link 265, the U-shaped plate 2643 is used to avoid the mounting structure of the second link 265 (e.g., bolts, pins, etc.), and the second mounting plate 2644 is used to connect to the support block 262.

[0076] In this implementation, it can be understood that, as Figure 9 As shown, the second link 265 of this application can also be configured as two, with the two second links 265 respectively hinged to the two ends of the third link 266, so as to further drive the third link 266 to rotate smoothly and reliably, and further improve the stability and reliability of the traction assembly 2 when switching from the traction state to the maintenance state.

[0077] In one embodiment of this application, such as Figures 6 to 9 As shown, the adjusting member 26 of this application may further include a first limiting block 2681 and a second limiting block 2682; the first limiting block 2681 is disposed between two first connecting rods 264 and both ends of the first limiting block 2681 are respectively connected to two second connecting rods 265. In the traction state, the first limiting block 2681 abuts against the third connecting rod 266; the second limiting block 2682 is disposed on the support block 262. In the maintenance state, the first connecting rod 264 abuts against the second limiting block 2682.

[0078] In this way, the first limiting block 2681 can be set in a more stable and reliable traction state, and the operating handle 263 can be effectively prevented from rotating in the opposite direction, so as to prevent the first traction wheel 23 and the second traction wheel 25 from getting too close, thereby avoiding structural damage or excessive compression.

[0079] Meanwhile, the second limit block 2682, which is set in this way, can make the traction assembly 2 more stable and reliable in the maintenance state, and can effectively prevent the operating handle 263 from being rotated too much, so as to avoid the adjustment plate 24 or other structures from being raised too much and causing spatial interference with other structures or components, thereby avoiding structural damage.

[0080] In one embodiment of this application, such as Figures 7 to 9 As shown, the end of the third link 266 away from the second link 265 is sleeved on the connecting rod 267. The connecting rod 267 includes a threaded section. The adjusting member 26 also includes two locking nuts 269. The two locking nuts 269 are respectively sleeved on the threaded section and the two locking nuts 269 clamp the third link 266 from the top and bottom directions respectively.

[0081] In this way, the third link 266, locking nut 269, and connecting rod 267 are configured in such a way that the connection between the third link 266 and the connecting rod 267 can be reliably and stably achieved under the condition of minimizing the size, and the assembly and disassembly of the third link 266 and the connecting rod 267 are convenient.

[0082] In existing related technologies, two interlocking cutters are generally used to cut strip-shaped packaging bags (e.g., Chinese patent document CN109733697A). However, this cutter design has the following problems: the fit between the two cutters needs to reach an extremely high standard, and the cutters themselves also have certain processing errors. The fit gap between the two cutters is difficult to adjust. If the fit gap is too large, it will result in ineffective cutting of the strip-shaped packaging bags, affecting production efficiency; if the fit gap is too small, it will generate greater cutting noise and increase equipment wear. This poses a great challenge to the installation and debugging of the cutters.

[0083] In view of this, in one embodiment of this application, such as Figures 10 to 15As shown, the package cutting component 3 of this application includes a first cutting component 31 and a second cutting component 32. The first cutting tool assembly 31 includes a fine-tuning bolt 311, a first tool holder 312, and two first blades 313. The first tool holder 312 is connected to a drive device so that it can be driven by the drive device to rotate. The first tool holder 312 has two oppositely arranged first slots 3121. The extension direction of the first slots 3121 is the same as the rotation axis direction of the first tool holder 312. The two first blades 313 are detachably installed in the two first slots 3121 respectively. The first tool holder 312 has a through adjustment hole 3122. The first tool holder 312 includes two oppositely arranged adjustment bolt holes 3123. One end of the two adjustment bolt holes 3123 is connected to the adjustment through hole 3122, and the other end is connected to the two first slots 3121 respectively. The adjustment bolt holes 3123 are used for threaded connection of the fine-tuning bolt 311. The adjustment bolt is used to abut against the first blade 313 to adjust the relative position of the first blade 313 and the first slot 3121.

[0084] The second cutting blade assembly 32 includes a second blade holder 321 and two second blades 322. The second blade holder 321 is connected to a drive device so that it can be driven by the drive device to rotate. The rotation direction of the second blade holder 321 is opposite to that of the first blade holder 312. The second blade holder 321 has two oppositely arranged second slots 3211. The extension direction of the second slots 3211 is in the same direction as the rotation axis of the second blade holder 321. The two second blades 322 are detachably installed in the two second slots 3211 respectively.

[0085] The cutting assembly 3 includes a cutting state in which the side of the first blade 313 away from the first blade holder 312 and the side of the second blade 322 away from the second blade holder 321 abut against each other to cut the package.

[0086] Through the above technical solution, compared with the existing related technologies, this application designs a brand-new bag cutting assembly 3. The adjustment bolt hole 3123 and the fine adjustment bolt 311 can adjust the position of the first blade 313 relative to the second blade 322, so that the fitting clearance between the first blade 313 and the second blade 322 can reach a better state, thereby ensuring that the fitting accuracy of the two meets the production needs. It can not only effectively ensure that the first blade 313 and the second blade 322 can reliably cut the strip packaging bag to improve production efficiency, but also effectively reduce cutting noise and reduce equipment wear.

[0087] In the above technical solution, it should be noted that, firstly, the method by which the first blade 313 is installed in the first slot 3121 can be implemented in various ways. For example, it can be a snap-fit ​​type (i.e., the first blade 313 is provided with a snap block, and the second slot 3211 is provided with a corresponding slot, and the first blade 313 is detachably installed by snapping the snap block into the slot), or a bolt fastener type (refer to the implementation of mounting bolt holes and fastening bolts below), or a pin type (i.e., a mounting hole is provided on the first blade 313, which can be a through hole or a blind hole, and a corresponding mounting through hole is opened on the first tool holder 312, and the first blade 313 is detachably installed by using a pin passing through the mounting hole and the mounting through hole). This application does not specifically limit this. Similarly, the second blade 322 can also be installed in the second slot 3211 in various ways, which will not be elaborated here.

[0088] Second, the principle of adjusting the fit gap between the first blade 313 and the second blade 322 by the fine-tuning bolt 311 in this application is as follows: Since the second blade 322 is installed in the second slot 3211, its relative position can be regarded as fixed. By turning the fine-tuning bolt 311, the fine-tuning bolt 311 abuts against the first blade 313 (during the fine-tuning process, the fixing structure of the first blade 313 can be slightly loosened, for example, the fastening bolt described below, so as to make it easier to adjust the position of the first blade 313) and pushes the first blade 313 toward the second blade 322 to make a small movement, thereby realizing the fine adjustment of the fit gap between the first blade 313 and the second blade 322.

[0089] Third, since the cutting assembly 3 provided in this application has two first blades 313 and two second blades 322, and the two first blades 313 and two second blades 322 are respectively arranged opposite to each other, two cutting states will be formed during the rotation of the first cutter holder 312 or the second cutter holder 321, which can also help improve the working efficiency of the cutting assembly 3 of this application in cutting the package.

[0090] Fourth, the first cutter holder 312 and the second cutter holder 321 of this application rotate in opposite directions. In this way, during the cutting state, the corresponding first blade 313 and second blade 322 can rotate in opposite directions to a position where they contact each other, thereby reliably and stably cutting the strip-shaped packaging bag, which helps to ensure the cutting effect and avoid the problem of being unable to cut.

[0091] In existing related technologies, for example, Chinese patent document CN109733697A (a high-speed baggage dispenser) uses two interlocking cutters to cut strip-shaped packaging bags. However, in actual application, the two interlocking cutters may often fail to cut the strip-shaped packaging bags. The applicant found that the reason is that both cutters have serrated blades. During the cutting process, the cutting process of the two cutters only occurs when the two cutters are in contact with the strip-shaped packaging bag. Since the strip-shaped packaging bag is flexible, when the two cutters are in contact with the strip-shaped packaging bag, the two sides of the strip-shaped packaging bag that are in contact with the cutters may fall naturally under the action of gravity. As a result, the two cutters cannot form sufficient clamping force on the strip-shaped packaging bag, and thus cannot cut the strip-shaped packaging bag.

[0092] In view of this, in one embodiment of this application, such as Figure 14 As shown, the first blade 313 of this application may include a blade body 3131 and a toothed cutting head 3132 connected to each other. The blade body 3131 is formed as a plate structure and is used to be detachably installed in the first slot 3121. The toothed cutting head 3132 protrudes from the first tool holder 312. The second blade 322 is formed as a plate structure and is used to be detachably installed in the second slot 3211, and a portion of the second blade 322 protrudes from the second tool holder 321. In the cutting state, the toothed cutting head 3132 and the second blade 322 abut against each other to cut the material bag.

[0093] In this way, during the process of cutting the material bag, the strip-shaped packaging bag located on both sides of the first blade 313 is supported by the end face of the second blade 322 and kept flat, so that the first blade 313 and the second blade 322 can form sufficient clamping force on the strip-shaped packaging bag, thereby effectively cutting the strip-shaped packaging bag.

[0094] It is understood that the blade body 3131 and the toothed blade head 3132 of this application can be integrally formed or solidly connected, and this application does not make specific limitations on this.

[0095] In one embodiment of this application, such as Figure 14 and Figure 15 As shown, the toothed cutter head 3132 of this application may include a first end 3132a and a second end 3132b disposed opposite to each other. The first end 3132a is connected to the blade body 3131, and the second end 3132b is formed into a zigzag structure, with all endpoints of the zigzag structure located on two parallel lines respectively.

[0096] With the toothed blade 3132 configured in this way, the first blade 313 and the second blade 322 can form a regular and uniformly stressed clamping state on the strip-shaped packaging bag, thereby enabling the first blade 313 and the second blade 322 to stably and reliably clamp the strip-shaped packaging bag.

[0097] In one embodiment of this application, as shown in the figure, the slicing assembly 3 further includes a second driving member 33. The second driving member 33 includes a drive motor 331, and a third gear 332 and a fourth gear 333 meshing with each other and having a gear ratio of 1:1. The output end of the drive motor 331 is connected to the first cutter holder 312 to drive the first cutter holder 312 to rotate. The third gear 332 is sleeved on the output end of the drive motor 331, and the fourth gear 333 is sleeved on the second cutter holder 321, so that the first cutter holder 312 and the second cutter holder 321 rotate at the same speed in opposite directions. Alternatively, the output end of the drive motor 331 is connected to the second cutter holder 321 to drive the second cutter holder 321 to rotate. The third gear 332 is sleeved on the output end of the drive motor 331, and the fourth gear 333 is sleeved on the first cutter holder 312, so that the first cutter holder 312 and the second cutter holder 321 rotate at the same speed in opposite directions.

[0098] In this way, the drive unit is configured in such a way that not only can the first tool holder 312 and the second tool holder 321 be driven simultaneously to save equipment space and reduce energy consumption, but also the first tool holder 312 and the second tool holder 321 can rotate at the same speed in opposite directions. In this way, during the cutting process, the corresponding first blade 313 and second blade 322 can rotate in opposite directions to the position of mutual contact, thereby reliably and stably cutting the strip-shaped packaging bag, which helps to ensure the cutting effect and avoid the problem of being unable to cut.

[0099] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
