Description

Technical Field

[0001] This utility model relates to a packaging machine device with quantitative material feeding, belonging to the field of packaging machinery technology. Background Technology

[0002] In modern packaging production lines, the efficient and accurate counting and quantitative collection of small packaging bags is a core link in ensuring the efficiency of subsequent processes, which is currently mostly achieved through automated equipment in the industry. Chinese patent publication number "CN112810934B" discloses a technical solution that estimates the number of bags by detecting the servo motor speed of the rotating frame driven by the bag-making and filling equipment, indirectly calculating the speed of the longitudinal sealing device, deriving the conveying speed of the bag feeding mechanism, and then using the formula "quantity = bag width / speed × time". This solution has certain limitations: the counting principle is too complex, requiring multiple calculations after detecting the motor speed; furthermore, the formula does not incorporate variables such as changes in bag spacing and bag deformation, and is only a theoretical estimate, failing to meet high-precision requirements. Multiple errors accumulate, causing the actual number of bags fed from the bag feeding mechanism to the dispensing mechanism to deviate from the preset value.

[0003] In summary, the development of a quantitative feeding and packaging device that combines precise counting is of great significance for improving the automation level and flexible adaptability of packaging lines. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the efficient and accurate counting and quantitative collection of small packaging bags involved in this application, the existing technical solution works as follows: by collecting the rotational speed of the servo motor driving the rotating frame of the bag-making and filling equipment, the operating speed of the longitudinal sealing device is indirectly calculated, and the conveying speed of the bag feeding mechanism is further determined. Finally, the number of bags is estimated based on the calculation formula "quantity = bag width / speed × time". However, this solution has limitations: firstly, the counting principle is too complex; secondly, the counting formula does not incorporate variables in actual production. The superposition of multiple errors will cause the actual number of bags fed from the bag feeding mechanism to the dispensing mechanism to deviate from the preset value.

[0029] This application proposes a packaging machine device with quantitative material feeding, which aims to at least solve the technical problem that "the actual amount of bags fed from the bag feeding mechanism to the material dispensing mechanism deviates from the preset value".

[0030] Please refer to 1- Figure 3 In this embodiment, a packaging machine device with quantitative material feeding includes a frame 100, a cutting mechanism 200, a bag feeding mechanism 300, and a material dispensing mechanism 400. The cutting mechanism 200 includes a cutter holder 210, a cutter assembly 220, and a photoelectric sensor 230. The cutter holder 210 is fixedly mounted on the frame 100, the cutter assembly 220 is rotatably mounted on the cutter holder 210, and the photoelectric sensor 230 is fixedly mounted on one side of the cutter assembly 220 and configured to detect the rotation frequency of the cutter assembly 220. The bag feeding mechanism 300 is arranged in a ring along a first direction on one side of the frame 100 for conveying packaging bags. The material distribution mechanism 400 includes a hopper body 410, a partition plate 420, and a swing plate 430. The hopper body 410 is located below the bag feeding mechanism 300 on the side opposite to the cutting mechanism 200. The hopper body 410 has a receiving cavity. The partition plate 420 is fixedly disposed in the receiving cavity. The swing plate 430 is disposed at one end of the partition plate 420 and swings relative to the partition plate 420. The partition plate 420 and the swing plate 430 cooperate to divide the receiving cavity into a first collecting cavity 410a and a second collecting cavity 410b.

[0031] When the equipment is in operation, the bag feeding mechanism 100 moves in a ring on the frame 100, and the bag feeding mechanism 300 transports the row of packaging bags to be cut to the cutting mechanism 200. The cutting blade group 220 of the cutting mechanism 200 cuts them into individual packaging bags through rotational motion. The cut packaging bags are then transported by the bag feeding mechanism 300 along the first direction until they reach the material distribution mechanism 400. The hopper body 410 of the material distribution mechanism 400 divides the accommodating cavity into two independent collection cavities through the configured swing plate 430 and partition plate 420. The two cavities are always in a "one open, one blocked" state. The bag feeding mechanism 300 will put the packaging bags into the blocked collection cavity for temporary storage. At the same time, the photoelectric sensor 230 obtains the number of rotations of the cutter group 220 by sensing the rotation frequency, and indirectly counts the cut packaging bags. When the count value reaches the preset value, the swing plate 430 triggers a state switch, so that the originally blocked collection cavity becomes open to discharge all the temporarily stored packaging bags. The originally open collection cavity simultaneously becomes blocked to receive the next batch of quantitative packaging bags conveyed by the bag feeding mechanism 300, realizing the cyclical operation of "cutting and counting - quantitative temporary storage - batch discharge".

[0032] When the slitting mechanism 200 performs the packaging bag slitting operation through the cutter group 220, the photoelectric sensor synchronously detects the rotation frequency of the cutter group 220 to realize the counting function of the slitting packaging bags. When the photoelectric sensor 230 counts to the preset value, it can coordinately control the swing plate 430 to perform the swing action, drive the material distribution mechanism 400 to complete the packaging bag discharge, and synchronously switch the collection chamber to perform subsequent material collection operations, thereby effectively improving the technical problem that the actual bag feeding amount from the bag feeding mechanism 300 to the material distribution mechanism 400 is inconsistent with the preset value.

[0033] The partition plate 420 configured on the hopper body 410, in coordination with the swing plate 430, divides the accommodating cavity of the hopper body 410 into two independent collection cavities, thereby realizing the dual-station alternating bag collection and discharge function. At the same time, the structural design of the partition plate 420 allows the collection cavity to have a larger volume, which can adapt to the needs of large-volume bag collection operations.

[0034] For example, the first direction is defined as the front-to-back direction. After the packaging bag is cut by the cutter group 220, it is transported by the bag feeding mechanism 300 along this direction to the hopper body 410 in front, and the delivery operation is completed.

[0035] For example, the preset value is a baseline value set according to actual operational needs.

[0036] For example, a row of bags refers to an integrated packaging unit in which multiple bags are connected to each other and have not yet been cut.

[0037] In some embodiments, the material distribution mechanism 400 further includes a rotating shaft 440, a first cylinder 450, and a swing arm 460. Please refer to the following references. Figures 3-4 A rotating shaft 440 passes through the hopper body 410 and is fixedly connected to the swing plate 430. A first cylinder 450 is fixedly located on the side of the hopper body 410 away from the swing plate 460. One end of the swing arm 460 is connected to the rotating shaft 440, and the other end is connected to the output end of the first cylinder 450. The first cylinder 450 is configured to push the swing arm 460 so that the swing arm 460 drives the rotating shaft 440 to rotate.

[0038] The swing plate 430 and the partition plate 420 work together to precisely divide the accommodating cavity of the hopper body 410 into two independent collection cavities. When the count value of the cut packaging bags detected by the photoelectric sensor 230 reaches the preset value, the first cylinder 450 will be triggered. The cylinder shaft drives the rotating shaft 440 to rotate around its own axis through the push-pull swing arm 460. Since the swing plate 430 and the rotating shaft 440 are fixedly connected, they form synchronous motion. The swing plate 430 will swing around the rotating shaft 440 as the axis. By changing the angle of the swing plate 430, the open / closed state of the two collection cavities can be switched, thereby realizing the dual-station operation of alternating bag collection and bag discharge.

[0039] By configuring the first cylinder 450 and the swing arm 460, an automated drive is provided for the swing plate 460, enabling it to achieve automated swinging. The swing angle of the swing plate 460 is precisely controlled by the stroke of the first cylinder 450. This design ensures that the swing plate 460 moves to the designated position, thereby allowing the collection chamber to stably switch between fully open and fully closed states. This control method helps to improve the bag jamming problem caused by incomplete opening of the collection chamber and the bag leakage phenomenon caused by incomplete sealing, ensuring the operational stability of the collection chamber during bag collection and discharge processes.

[0040] For example, a pivot hole is provided in the middle of the hopper body 410, a pivot shaft 440 is rotatably inserted through the pivot hole, and a partition plate 420 is provided on the upper side of the pivot hole.

[0041] For example, the hopper body 410 is also provided with a protective seat 411, and the rotating shaft 440 is located in the protective seat 411.

[0042] In some embodiments, the cutter assembly 220 includes a first cutter 221 and a second cutter 222. Please refer to [reference needed]. Figure 2 The first cutter 221 is rotatably mounted on the cutter holder 210, and the second cutter 222 is rotatably mounted on the cutter holder 210. The rotation direction of the second cutter 222 is opposite to that of the first cutter 210. The bag feeding mechanism 300 is configured to have a bag feeding stroke path. The row of packaging bags passes between the first cutter 221 and the second cutter 222 along the bag feeding stroke path, so that the first cutter 221 and the second cutter 222 cooperate with each other to cut the row of packaging bags.

[0043] When the equipment is in operation, multiple packaging bags to be cut are conveyed by the bag feeding mechanism 300 and pass through the cutting area formed by the first cutter 221 and the second cutter 222 along the bag feeding stroke path. During the operation, the first cutter 221 and the second cutter 222 perform relative rotation, thereby cooperating to accurately cut the continuously conveyed packaging bags, so that the row of packaging bags is separated into independent units.

[0044] The first cutting blade 221 and the second cutting blade 222 form a stable shearing cooperation structure through relative rotation. When cutting the packaging bags to be cut, a uniform shearing force can be applied to the continuously conveyed material. This helps to improve the cutting quality defects such as edge tearing and burrs that are common in single-blade cutting mode, and improves the flatness and integrity of the edges of the packaging bags after cutting. At the same time, compared with the reciprocating cutting operation of a single blade, the cutting design with relative rotation of the double blades can distribute the stress load of a single cut to the two blades, thereby reducing the instantaneous stress intensity of a single blade and reducing the damage to the blades caused by local stress concentration.

[0045] For example, the first cutter 221 and the second cutter 222 are constructed as mirror images of each other.

[0046] For example, the bag delivery path is a specific conveying trajectory set according to actual operational needs.

[0047] For example, the cutting area is the area where the first cutter 221 and the second cutter 222 are set opposite each other. This area has the functional attribute of allowing the packaging bag to pass through along the bag feeding path, while providing the necessary space for the first cutter 221 and the second cutter 222 to perform cutting operations on the passing packaging bag.

[0048] Optionally, the first cutter 221 is fixedly provided with a first cutter gear 223, and the second cutter 222 is fixedly provided with a second cutter gear 224. The transmission ratio of the two cutter gears is 1:1, and a transmission structure is formed through two first transition gears 225, thereby driving the first cutter 221 and the second cutter 222 to rotate synchronously relative to each other.

[0049] In some embodiments, a plurality of first cutting edges 221a are spaced apart on the outer surface of the first cutter 221, and a plurality of second cutting edges 222a are spaced apart on the outer surface of the second cutter 222. Please refer to the reference. Figure 2 The first cutting edge 221a and the second cutting edge 222a are set in a one-to-one correspondence.

[0050] During the slitting operation, the first cutter 221 and the second cutter 222 perform relative rotation. The first blade 221a and the second blade 222a form a cooperative shearing action. When the packaging bag to be slitting is conveyed by the bag feeding mechanism 300 to the cutting area between the first cutter 221 and the second cutter 222, the first blade 221a and the second blade 222a generate shearing force through relative rotation, which is precisely applied to the position of the packaging bag to be slitting, so that the row of packaging bags is slitting and the packaging bags are separated into independent units that meet the specifications.

[0051] By arranging multiple sets of cutting edges (i.e., first cutting edge 221a and second cutting edge 222a) at preset intervals on the working surfaces of the first cutting edge 221 and the second cutting edge 222, a multi-blade collaborative cutting structure is constructed. During the equipment's slitting operation, the two cutting edges synchronously perform relative rotation. With each rotation, the multiple sets of cutting edges on their surfaces sequentially form a shearing engagement with the opposite cutting edge, thereby completing multiple continuous slitting actions. This design is beneficial for efficiently handling continuously conveyed rows of packaged bags, accurately slitting the originally connected materials into independent units that meet the size and shape specifications, significantly improving the slitting efficiency per unit time and adapting to high-capacity operation requirements.

[0052] For example, the number of first cutting edge 221a and second cutting edge 222a can be two, three, four, etc., for example, refer to Figure 2 There can be four first cutting edges 221a and four second cutting edges 222a.

[0053] In some embodiments, the slitting mechanism 200 is provided with a set.

[0054] Under operating conditions, multiple packaging bags to be cut are continuously conveyed by the bag feeding mechanism 300. The bag feeding mechanism 300 adopts a fixed-distance conveying mode. For each unit length of packaging bag conveyed (i.e., the preset conveying stroke of a single packaging bag), the cutter group 220 rotates simultaneously to perform a cutting action. Through a single cutting operation, the cutter group 200 accurately separates the continuously conveyed packaging bag material belt, so that each packaging bag is sequentially cut into independent units.

[0055] In some embodiments, the slitting mechanism 200 is provided in two sets; please refer to the relevant documentation. Figure 1 , Figure 6 The two cutting mechanisms 200 are spaced apart along the first direction.

[0056] Under operating conditions, multiple packaging bags to be cut are continuously conveyed by the bag feeding mechanism 300. The bag feeding mechanism 300 adopts a fixed-distance conveying mode. Every time two unit lengths of packaging bags are conveyed (i.e., the preset conveying stroke of two packaging bags), the cutting blade assembly 220 rotates simultaneously to perform a cutting action. Through a single cutting operation, the cutting blade assembly 220 directly separates the two continuously conveyed packaging bags synchronously, making them into independent units in sequence. Compared with the cutting method with only one cutting blade assembly 220, this design can complete the cutting of two packaging bags in a single action, significantly improving the packaging bag cutting efficiency, and thus effectively improving the overall production efficiency.

[0057] For example, the two-part slitting mechanism 200 has the same structure.

[0058] Optional, please refer to the following: Figure 2 , Figure 6 The second cutter gears 224 of the two cutting mechanisms 200 are connected by multiple second transition gears 226, and the rotation frequency of the two cutting groups 220 is consistent. At the same time, the second transition gears 226 are meshed with a power gear 227, which is driven by a motor to achieve rotational motion.

[0059] Optionally, the second transition gear 226 may include a spur gear and a bevel gear.

[0060] In some embodiments, the cutter holder 210 is fixed with a mounting base 211; please refer to the relevant documentation. Figure 2 The photoelectric sensor 230 is fixedly mounted on the mounting base 211.

[0061] For example, the photoelectric sensor 230 is fixedly mounted on the mounting base 211 and the mounting position is located above the first cutter 221. The photoelectric sensor 230 detects the number of rotations of the first blade 221a in real time and converts the detection signal into data information, thereby accurately obtaining the rotation frequency parameters of the cutter group 220.

[0062] In some embodiments, the slitting mechanism 200 further includes an adjusting assembly 240, which comprises a sliding plate 241 and a second cylinder 242. Please refer to [reference needed]. Figure 2 , Figure 5The cutter holder 210 has first adjustment grooves 210a on both its upper and lower sides, extending along a second direction. Two sliding plates 241 are correspondingly disposed within the first adjustment grooves 210a and are adjustable relative to them. The first cutter 221 has a first shaft 221b, which is rotatably connected to the two sliding plates 241. A second cylinder 242 is fixedly disposed on one side of the cutter holder 210, and the sliding plates 241 are connected to the output end of the second cylinder 242. The second direction is perpendicular to the first direction, and the second cylinder 242 is configured to push the sliding plates 241 to adjust the distance between the first cutter 221 and the second cutter 222.

[0063] The second cylinder 242, through the extension and retraction of its cylinder shaft, drives the sliding plate 241 to slide linearly along the guide trajectory of the first adjusting groove 210a. Since the first cutter 221 is mounted on the sliding plate 241, the displacement of the sliding plate 241 can cause the first cutter 221 to move synchronously, thereby achieving position adjustment of the first cutter 221 relative to the second cutter 222. This structural design allows for precise fine-tuning of the distance between the first cutter 221 and the second cutter 222 via the second cylinder 242, flexibly adapting to the slitting needs of packaging bags of different thicknesses and specifications. It eliminates the need for frequent disassembly and replacement of the cutter assembly 220, effectively improving the equipment's compatibility with various material specifications.

[0064] For example, the second direction is defined as the left and right direction. The first cutter 221 can be moved left and right by the cooperation of the sliding plate 241 and the second cylinder 242, thereby adjusting the distance between it and the second cutter 222.

[0065] For example, the second cutter 222 has a second shaft 222b and is rotatably connected to the cutter holder 210 through the second shaft 222b. The first cutter gear 223 is fixedly disposed on the first shaft 221b and the second cutter gear 224 is fixedly disposed on the second shaft 222b.

[0066] For example, please refer to the following: Figure 5 The sliding plate 241 has a shaft hole 241a that passes through the upper and lower surfaces. The first shaft 221b passes through the shaft hole 241a so that the first cutter 221 is rotatably connected to the sliding plate 241. At the same time, the sliding plate 241 also has a groove 241b extending in the second direction. The sliding plate 241 slides against the inner wall of the first adjusting groove 210a through the groove 241b.

[0067] In some embodiments, please refer to Figure 2 The adjustment component 240 includes two second cylinders 242, which are configured one-to-one with two sliding plates 241.

[0068] By configuring two second cylinders 242, and connecting the two second cylinders 242 to the two sliding plates 242 in a one-to-one correspondence, a dual-power drive structure is formed. This structure can effectively reduce the single-cylinder drive load when pushing the first cutter 221 for position adjustment, realize the effortless pushing of the first cutter 221, and improve the convenience and stability of the adjustment operation.

[0069] In some embodiments, the bag feeding mechanism 300 includes a drive shaft 310, a driven shaft 320, a sprocket assembly 330, and a gripper 340. Please refer to [reference needed]. Figures 6-8 The drive shaft 310 is rotatably mounted on one side of the frame 100, and the driven shaft 320 is rotatably mounted on one side of the frame 100, away from the drive shaft 310. The drive shaft 310 is connected to the driven shaft 320 via the sprocket assembly 300. Multiple grippers 340 are spaced apart on the sprocket assembly 330 for gripping packaging bags.

[0070] In the packaging bag conveying process, the packaging bags to be cut are positioned and clamped by the gripper 340. The sprocket assembly 330, through the cooperation of the drive shaft 310 and the driven shaft 320, drives the clamped packaging bags to move steadily along the first direction until they reach the cutting operation area of ​​the cutter group. The cutter group 220 completes the cutting action. After the cutting is completed, the sprocket assembly 330 continues to drive the gripper 340 and the cut packaging bags to move along the first direction until they reach the material distribution mechanism 400. At this time, the gripper 340 performs the bag release action, releasing the cut individual packaging bags so that they fall into the hopper body 410 under the action of gravity, completing the continuous process of conveying-cutting-collecting.

[0071] The sprocket assembly 330 can drive the gripper 340 and the packaging bag to move precisely in the first direction, which helps to improve the problem of conveying speed fluctuation or displacement deviation, ensure the consistency of the cutting position, and the sprocket assembly 330 has a strong load-bearing capacity, which can stably cope with the load requirements of continuous conveying of multiple packaging bags and reduce the risk of failure of the transmission structure due to excessive force.

[0072] Optionally, the drive shaft 310 is fixed with a drive shaft gear 310a that meshes with the power gear 227, so that it can be driven to achieve rotational action.

[0073] In some embodiments, the sprocket assembly 330 includes a driving sprocket 331, a driven sprocket 332, and a chain 333. Please refer to [reference needed]. Figure 6 , Figure 8 The driving sprocket 331 is fixedly sleeved on the driving shaft 310, and the driven sprocket 332 is fixedly sleeved on the driven shaft 320. The driving sprocket 331 is connected to the driven sprocket 332 through the chain 333. Multiple clamps 340 are arranged at intervals on the chain 333.

[0074] When the drive shaft 310 rotates, it drives the drive sprocket 331, which is fixed to it, to rotate synchronously. The drive sprocket 331 forms a transmission engagement with the driven sprocket 332 through the chain 333, and transmits power to the driven sprocket 332, thereby driving the driven shaft 320 to rotate synchronously with the driven sprocket 332, forming a complete sprocket transmission system. During the cyclic transmission of the chain 333 with the drive sprocket 331 and the driven sprocket 332, the gripper 340 remains connected to the chain 333. The transmission action of the chain 333 can synchronously drive the gripper 340 to move along the bag feeding path, providing stable power and directional guidance for the conveying of the packaging bag.

[0075] For example, the transmission ratio of the driving sprocket 331 and the driven sprocket 332 is 1:1.

[0076] In some embodiments, the gripper 340 includes a clamping base 341 and a clamping block 342. Please refer to [reference needed]. Figures 9-10 The clamp 341 is fixedly connected to the sprocket assembly 330. An iron block 341a is fixed to the clamp 341. A clamping block 342 is rotatably connected to the clamp 341 and a magnetic element 342a is fixed to the clamping block 342. The gripper 340 has a clamping state and an open state. In the clamping state, the magnetic element 342a and the iron block 341a are magnetically attracted to each other, causing the gripper 340 to clamp the packaging bag. In the open state, the magnetic element 342a and the iron block 341a are relatively separated, causing the gripper 340 to release the packaging bag.

[0077] In the packaging bag conveying process, the clamping block 342 achieves relative closure with the clamping seat 341 through the magnetic attraction between the magnetic component 342a and the iron block 341a, forming a stable clamp on the edge of the packaging bag. After the clamping action is completed, the clamping device 340 moves synchronously with the chain 333, accurately conveying the packaging bag to the cutting station of the cutting knife group 220. After the cutting action is completed, the clamping seat 341 and the clamping block 342 maintain the clamping state of the packaging bag and continue to drive it to the direction of the material distribution mechanism 400. When it reaches the preset position of the material distribution mechanism 400, the magnetic component 342a and the iron block 341a move away from each other, the magnetic attraction is released, and the clamping block 342 and the clamping seat 341 open relative to each other. The packaging bag, which has lost its clamping force, falls into the hopper body 410 under the action of gravity.

[0078] Optionally, a connecting portion 333a is formed on the link of the chain 333, and the clamp 341 is fixed to one side of the connecting portion 333a by bolts, and a gasket 343 for improving structural stability is provided between the clamp 341 and the connecting portion 333a.

[0079] Optionally, the clamping block 342 is used to form anti-slip teeth at one end that clamps with the clamping seat 341. The anti-slip teeth help improve the clamping stability of the gripper 340 on the packaging bag.

[0080] In some embodiments, the bag feeding mechanism 300 further includes a third cylinder 350. A plurality of third cylinders 350 are spaced apart on one side of the gripper 340. At least one third cylinder 350 is located above the first collection chamber 410a, and at least another third cylinder 350 is located in the second collection chamber 410b. Each of the output ends of the plurality of third cylinders 350 is provided with a push block 351. The gripper 340 is provided with a cam portion 342b. The push block 351 is configured to push the cam portion 342b to open the gripper 340.

[0081] During the movement of the packaging bag gripped by each gripper 340, the switching of the collection chamber is performed based on the counting result of the photoelectric sensor 230. When the count of the photoelectric sensor 230 has not reached the preset value, the cylinder shaft of the third cylinder 350 above the first collection chamber 410a is in the extended state, while the cylinder shaft of the third cylinder 350 above the second collection chamber 410b is in the retracted state. The cam portion 342b of the clamping block 342 is pushed by the push block 351 of the corresponding third cylinder 350 at the position of the first collection chamber 410a, causing the packaging bag to fall into the first collection chamber 410a. When the count of the photoelectric sensor 230 is less than the preset value, the switching of the collection chamber is performed based on the counting result of the photoelectric sensor 230. When the count reaches the preset value, the cylinder shaft of the third cylinder 350 corresponding to the two collection chambers switches to the extension and retraction state. The cam part 342b of the clamping block 342 is pushed by the corresponding push block 351 at the position of the second collection chamber 410b, causing the packaging bag to fall into the second collection chamber 410b. When the count of the photoelectric sensor 230 reaches the preset value again, the cylinder shaft of the third cylinder 350 switches to the extension and retraction state again, causing the packaging bag to fall back into the first collection chamber 410a. The alternating collection function of the two collection chambers is realized through the above control logic cycle.

[0082] For example, the frame 100 is provided with a first mounting plate 110, and the third cylinder 350 is fixedly connected to the first mounting plate 110.

[0083] In some embodiments, a third cylinder 350 is provided above the first collection chamber 410a, and another third cylinder 350 is provided above the second collection chamber 410b.

[0084] In some embodiments, the bag feeding mechanism 300 further includes a baffle 360. Please refer to [reference needed]. Figure 6 , Figure 10 The baffle 360 ​​is fixedly connected to the first mounting plate 110 and is located on one side of the clamp 340.

[0085] When the third cylinder 350 pushes the cam 342b to open the clamp 342, the baffle 360 ​​can apply a limiting effect to the clamp 341. This limiting effect helps to improve the offset problem of the clamp 341 caused by the force of the clamp 342, thereby reducing the deformation or slack of the chain 333.

[0086] For example, the rack 100 is provided with multiple first mounting plates 110, and the baffle 360 ​​is fixedly connected to the first mounting plates 110 one by one through multiple connecting seats 361.

[0087] In some embodiments, the bag feeding mechanism 300 further includes an adjusting seat 370 and a fastening bolt 371. Please refer to [reference needed]. Figures 7-8 An adjusting seat 370 is disposed on the surface of the second mounting plate 120 of the frame 100. The adjusting seat 370 is provided with an insertion hole 370a and a second adjusting groove 370b. The second adjusting groove 370b extends in a long strip along the first direction. The second mounting plate 120 is provided with a slot 120a and a positioning hole 120b. The slot 120a extends along the first direction. The fastening bolt 371 passes through the second adjusting groove 370b and the positioning hole 120b in sequence and is connected to the second mounting plate 120. The driven shaft 320 is rotatably disposed on the adjusting seat 370 and passes through the insertion hole 370a and the slot 120a in sequence. The adjusting seat 370 adjusts the position of the driven shaft 320 relative to the second mounting plate 120 by the position difference between the positioning hole 120b and the second adjusting groove 370b.

[0088] After loosening the fastening bolt 371, the adjusting seat 370 can slide along the first direction on the second mounting plate 120. Since the driven shaft 320 is mounted on the adjusting seat 370, the sliding of the adjusting seat 370 will synchronously change the position of the driven shaft 320. By adjusting the center distance between the driven shaft 320 and the driving shaft 310, the tension of the chain 333 can be adjusted.

[0089] Optionally, a side plate 121 is fixedly connected to one side of the second mounting plate 120, and a reinforcing bolt 122 is provided between the side plate 121 and the adjusting seat 370.

[0090] In some embodiments, the drive shaft 310 rotates on the third mounting plate 130 disposed on the frame 100.

[0091] In some embodiments, a PLC controller is also included, which is electrically connected to the cutting mechanism 200, the bag feeding mechanism 300, and the material dispensing mechanism 400.

[0092] As the core control unit of the equipment, the PLC controller establishes electrical connections with the various circuit components of the slitting mechanism 200, bag feeding mechanism 300, and material distribution mechanism 400. By receiving detection signals from the photoelectric sensor 230, the PLC controller can acquire real-time equipment operating status data and, according to the preset control program, output control commands to the slitting mechanism 200, bag feeding mechanism 300, and material distribution mechanism 400 respectively, coordinating and regulating the opening and closing sequence and operating parameters of each mechanism to ensure orderly connection of each process and realize automated collaborative operation of the equipment.
