Description

TECHNICAL FIELD

[0001] The present application relates to packaging equipment, more particularly, it relates to a syringe packaging system. BACKGROUND

[0002] In the medical industry, disposable syringes are widely used. Due to their convenient and safe and sanitary characteristics, disposable syringes have been widely used in various medical scenarios. However, the current packaging method of disposable syringes has many problems, mainly relying on manual operation. Manual packaging not only has low efficiency, but also easily causes bacteria to adhere to the packaging bag, thereby causing the product to be unqualified in hygiene, increasing production costs, and being not conducive to large-scale production.

[0003] The existing automatic packaging technology also has some shortcomings:

[0004] Patent document CN104590621B discloses an automatic packaging machine for disposable syringes, which realizes automatic packaging through the cooperation of multiple mechanisms, but still has some limitations:

[0005] Structural complexity: The packaging machine needs a feeding mechanism to arrange the disposable syringes in the feeding screw groove one by one, and then a taking mechanism to suck the syringes by vacuum suction cups and transport them forward to the receiving groove of the bag receiving mechanism. The whole process needs precise cooperation of multiple motors, lead screws, sliding rails and other components, the structure is relatively complex, which increases the manufacturing cost and maintenance difficulty of the equipment.

[0006] Packaging efficiency: Although automatic packaging is realized, there may be some delay in the taking, bag receiving and pushing steps, which leads to slow packaging speed and makes it difficult to meet the high efficiency demand of large-scale production.

[0007] Safety: Although manual contact is reduced during packaging, the complex structure of the equipment may cause some safety hazards, such as pinching accidents caused by the movement of mechanical parts.

[0008] Patent document CN105000205B discloses a syringe packaging machine, which realizes automatic packaging of syringes through a series of devices such as syringe feeding mechanism, conveying mechanism, taking mechanism, flat pushing mechanism, bag storage mechanism, taking mechanism, tray translation mechanism and sealing mechanism. However, this scheme also has some shortcomings:

[0009] Cost problem: Multiple independent mechanisms and driving devices need to be set, such as the inclined turntable of the syringe feeding mechanism, the synchronous belt and clamp of the syringe conveying mechanism, the sliding plate and push rod of the syringe flat pushing mechanism, etc., which makes the manufacturing cost of the equipment higher, and some small and medium-sized production enterprises may not be able to afford it.

[0010] Operation complexity: due to the coordination of multiple agencies involved in the action, the operation and maintenance personnel need to have a high level of technical expertise to master the operation method and maintenance points of the equipment, otherwise it is easy to malfunction, affecting the production schedule.

[0011] In view of the deficiencies of the prior art, the present application aims to provide a syringe packaging system with reasonable structure, low cost, safety and reliability, to overcome the defects in the prior art and meet the high efficiency, safety and hygiene requirements of the medical industry for disposable syringe packaging.

DETAILED DESCRIPTION

[0050] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the protection scope of the present application.

[0051] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0052] As shown in Figure 1 and Figure 2 , the syringe packaging system comprises a syringe conveying device 1, a packaging processing device 2 and a cutting processing device 3. The syringe conveying device 1 comprises a feeding mechanism 11, a transfer mechanism 12, a conveying mechanism 13 and a discharging mechanism 14, the feeding mechanism 11 is used to convey the syringes to the transfer mechanism 12, the transfer mechanism 12 is used to transfer the syringes to the conveying mechanism 13, and the conveying mechanism 13 is used to convey the syringes to the discharging mechanism 14; the packaging processing device 2 comprises a base material conveying mechanism 21, a forming mechanism 22, an auxiliary material conveying mechanism 23 and a fusion welding mechanism 24, the base material conveying mechanism 21 is used for pulling transmission of the base material, the forming mechanism 22 is used for forming a syringe accommodating cavity on the base material (PE, PET material), the discharging mechanism 14 is used to grab the syringes on the conveying mechanism 13 into the accommodating cavity, the auxiliary material conveying mechanism 23 is used to convey and pull the auxiliary material (medical dialysis paper coated with a glue layer, which is melted by heat) to the base material, and the fusion welding mechanism 24 is used to melt and bond the auxiliary material and the base material and seal the syringe in the accommodating cavity; the cutting processing device 3 comprises a cutting mechanism 31, a material separating mechanism 32 and a waste edge collecting mechanism 33, the material separating mechanism 32 is used for longitudinal product separation, the cutting mechanism 31 is used for transverse product separation, and the waste edge collecting mechanism 33 is used for collecting the generated waste edges.

[0053] The feeding mechanism 11 transfers the syringes from the initial position to the processing line. The device can be a combination of a transmission belt 111a with a limiting channel 102 and a sliding plate 112a. The physical guidance achieves the directional arrangement of the syringes. The transfer mechanism 12 is used to connect the feeding mechanism 11 and the transmission mechanism 13. The device can be a combination of a disc with a transfer gap 1201 and an arc-shaped guide ring 122. The rotational motion transfers the syringes. The forming mechanism 22 is a device for forming a containing cavity on the base material. The device can be a hot forming die set. After softening the base material by heating, the mold forming is achieved. The fusion welding mechanism 24 is a device for sealing the packaging material. The device can be a hot pressing channel with an arc-shaped material supporting plate. The gradual pressure ensures the reliability of the sealing. The scrap edge collection mechanism 33 processes the cutting waste. The device can be a traction wheel set with a counterweight sliding block. The gravity self-adapting adjustment adjusts the waste winding tension.

[0054] Specifically, the syringes complete directional arrangement through the limiting channel 102 of the transmission belt 111a, and then enter the transfer gap 1201 of the transfer mechanism 12 through the sliding plate 112a. During the rotation of the transfer disc 121, the arc-shaped guide ring 122 restricts the syringes in the transfer space 104 until they are transferred to the limiting clamping seat of the transmission mechanism 13. The base material conveying mechanism 21 continuously supplies the base material to the forming station. The lower mold assembly cooperates with the upper mold assembly to mold the containing cavity on the surface of the base material after heating. The suction nozzle of the discharging mechanism 14 accurately grabs the syringes on the transmission chain to the forming cavity, and the auxiliary material conveying mechanism 23 synchronously covers the protective film. The base material and the auxiliary material are guided into the fusion welding channel by the arc-shaped material supporting plate, and are fused and sealed under the action of the heating element. The longitudinal material dividing cutter wheel cuts the independent packaging units along the gap between the material pressing rollers. The transverse cutting knife completes the final product segmentation, and the scrap edge is dragged to the collection wheel by the adjusting wheel for automatic winding.

[0055] As Figure 3As shown, the substrate conveying mechanism 21 comprises a cabinet 211, a feeding assembly 212, a first tension adjusting assembly 213 and a conveying assembly 214. The conveying assembly 214 comprises two film clamping chains 211a, rotating rollers 211b and four sprockets 211c disposed on the cabinet 211, each of the film clamping chains 211a corresponding to two sprockets 211c. The feeding assembly 212 comprises an air inflation shaft 212a rotationally connected with the cabinet 211, a locking disc 212b detachably connected with the air inflation shaft 212a, a first air cylinder 212c fixed on the cabinet 211 and a brake block 212d connected with the output end of the first air cylinder 212c, the first air cylinder 212c driving the brake block 212d to move and correspondingly cooperate with the air inflation shaft 212a. The first tension adjusting assembly 213 comprises a rotating plate 213a, a first traction roller 213b, a second traction roller 213c and a third traction roller 213d, the rotating plate 213a being L-shaped, one end of the rotating plate 213a being rotationally connected with the cabinet 211, the first traction roller 213b being fixed on the other end of the rotating plate 213a, the second traction roller 213c and the third traction roller 213d both being fixed on the cabinet 211 and both being disposed above the first traction roller 213b, the third traction roller 213d corresponding to the rotating roller 211b.

[0056] The film clamping chain 211a is a closed loop chain structure driven by the sprocket 211c, which can be implemented by a metal chain with clamping protrusions, for clamping the edge of the substrate and driving it to transmit along a straight line. The rotating roller 211b is a cylindrical roller body with smooth surface, which can be implemented by a steel roller body with chrome plating treatment, for changing the transmission direction of the substrate and reducing the friction resistance. The air inflation shaft 212a is a reel support shaft that can be inflated, which can be implemented by an axis body with an air bag structure inside, for quickly fixing the substrate reel with different inner diameters. The locking disc 212b is a disc structure with a locking groove, which can be implemented by a metal disc body with a spring buckle, for clamping and fixing the substrate reel with the end of the air inflation shaft 212a. The brake block 212d is a braking component with friction material, which can be implemented by a block structure of ceramic composite material or metal material, for generating braking torque by contacting the surface of the air inflation shaft 212a. The rotating plate 213a is a plate structure that can swing around the shaft, which can be implemented by an L-shaped or Z-shaped bent steel plate, for supporting the first traction roller 213b and automatically adjusting the angle according to the change of the substrate tension.

[0057] Specifically, two film clamping chains 211a form a closed-loop transmission path under the symmetrical arrangement of four sprockets 211c, and the substrate edges are clamped to realize synchronous linear conveying. The inflatable shaft 212a is tightly attached to the inner wall of the substrate roll after inflation, and the locking disc 212b is quickly assembled and disassembled through the buckle structure, which can conveniently replace the substrate roll and clamp the substrate on the rotating shaft. The first cylinder 212c pushes the brake block 212d against the surface of the inflatable shaft 212a to form a braking force, keeping the tension constant during the unwinding process. The rotating plate 213a swings when the substrate tension changes, driving the first traction roller 213b to move up and down, and the second traction roller 213c and the third traction roller 213d form a fixed transmission path. When the substrate is loose, the rotating plate 213a swings down to tighten the material, and when it is too tight, it swings up to release the tension.

[0058] As shown in Figure 4 and Figure 5 , the forming mechanism 22 includes a second cylinder 221, a lower mold assembly 222, and an upper mold assembly 223. The second cylinder 221 drives the lower mold assembly 222 to move towards the upper mold assembly 223. The lower mold assembly 222 includes a mounting frame 222a, a heating module 222b, a pre-forming module 222c, and a lower forming module 222d. The output end of the second cylinder 221 is fixedly connected with the mounting frame 222a. The pre-forming module 222c and the lower forming module 222d are fixed on the mounting frame 222a. The heating module 222b is embedded in the mounting frame 222a and is used to provide a heat source for the pre-forming module 222c and the lower forming module 222d. The upper mold assembly 223 includes a positioning frame 223a, a mounting box 223b, a third cylinder 223d, and an upper forming module 223e. The positioning frame 223a is fixedly connected with the mounting box 223b. The positioning frame 223a is a rectangular frame and corresponds to the pre-forming module 222c. The third cylinder 223d is fixed on the mounting box 223b. The output end of the third cylinder 223d is connected with the upper forming module 223e. The upper forming module 223e corresponds to the lower forming module 222d.

[0059] The heating unit of the heating module 222b embedded in the mounting frame 222a can be implemented by an array of electric heating tubes, which realizes heat conduction by directly contacting the pre-forming module 222c and the lower forming module 222d. The pre-forming module 222c is a mold component for preliminary forming of the substrate, which can be implemented by a metal module with a protruding structure to guide the plastic deformation of the substrate through geometric shapes. The lower forming module 222d is a mold component for completing the final forming, which can be implemented by a metal module with a cavity structure to continue the forming work to form the accommodating cavity of the syringe based on the pre-forming. The positioning frame 223a is a guide structure for positioning the upper and lower molds, which can be implemented by a rectangular metal frame to form physical limiting through geometric correspondence with the pre-forming module 222c.

[0060] Specifically, the second cylinder 221 pushes the mounting frame 222a to move the preforming module 222c and the lower forming module 222d as a whole upward the module assembly 223, and the heat generated by the heating module 222b is conducted to the preforming module 222c and the lower forming module 222d. When the preforming module 222c contacts the base material, the geometric correspondence between the positioning frame 223a and the preforming module 222c ensures accurate alignment of the upper and lower molds, and the base material is preliminarily deformed under the action of the protruding structure of the preforming module 222c to form a relatively shallow groove. After the preformed base material is pulled to the forming station by the conveying assembly 214, the third cylinder 223d pushes the upper forming module 223e to move downward to cooperate with the lower forming module 222d to complete the final forming of the base material and form the final accommodating cavity on the relatively shallow groove. The setting of the preforming station cooperates with the forming station to greatly improve the yield rate of the accommodating cavity forming through secondary forming.

[0061] As shown in Figure 6 and Figure 7 , the auxiliary material conveying mechanism 23 includes a feeding roller 231, a second tension adjusting assembly 232, a flattening assembly 233, and a pressing assembly 234. The feeding roller 231 is used for placing and feeding the auxiliary material. The second tension adjusting assembly 232 includes a swing roller 232a and a guide roller 232b. The flattening assembly 233 includes a limiting roller 233a, a flattening plate 233b, and a traction roller 233c. The pressing assembly 234 includes a pressing frame 234a, a lifting roller 234b, and two lower pressing rollers 234c.

[0062] The feeding roller 231 is a roller shaft structure for carrying and releasing the auxiliary material roll, and a motor can be connected to the end thereof to control the feeding speed. The swing roller 232a in the second tension adjusting assembly 232 adjusts the tension of the auxiliary material in real time by changing the swing angle thereof, and a counterweight or a spring mechanism can be used to achieve dynamic balance. The guide roller 232b is a fixed-path roller body for constraining the transmission trajectory of the auxiliary material. The limiting roller 233a of the flattening assembly 233 is a roller body with a width limiting structure, and a roller cylinder with flanges on both sides can be used to limit the lateral deviation of the auxiliary material. The flattening plate 233b is a plate with a smooth surface for eliminating wrinkles by contacting the surface of the auxiliary material. The lifting roller 234b of the pressing assembly 234 is a roller body with adjustable height, and a cylinder can be used to achieve vertical displacement. The two lower pressing rollers 234c are fixed rollers symmetrically distributed on both sides of the lifting roller 234b, and form a wave-shaped path of the auxiliary material through three-point contact to adjust the tension.

[0063] Specifically, the auxiliary material is released from the feed roller 231, passes through the second tension adjusting assembly 232 composed of the swing roller 232a and the guide roller 232b, the swing roller 232a automatically adjusts the swing angle according to the change of the auxiliary material tension, and keeps the tension constant. The auxiliary material then enters the smoothing assembly 233, the limiting roller 233a restricts its transverse position, the smoothing plate 233b eliminates surface wrinkles through friction, and the traction roller 233c provides the extension direction of the auxiliary material. After the auxiliary material enters the pressing assembly 234, the lifting roller 234b lifts the auxiliary material upward to form a protruding part, and the two downward pressing rollers 234c respectively apply downward pressure to the auxiliary material on both sides to form a wave-shaped path to adjust the local tension, finally making the auxiliary material flat and adhere to the surface of the base material.

[0064] As shown in Figure 8 The feeding mechanism 11 includes a driving transmission assembly 111 and a material sliding assembly 112. The driving transmission assembly 111 includes two transmission belts 111a and two limiting plates 111b. The two transmission belts 111a form a transmission channel 101, and the two limiting plates 111b form a limiting channel 102. The transmission channel 101 and the limiting channel 102 correspond to each other. The material sliding assembly 112 includes two sliding plates 112a, which form a sliding channel 103 that communicates with the limiting channel 102. The transfer mechanism 12 includes a transfer disc 121 and an arc-shaped guide ring 122. The transfer disc 121 is provided with a plurality of transfer notches 1201 corresponding to the sliding channel 103. The arc-shaped guide ring 122 cooperates with the transfer notches 1201 to form a transfer space 104.

[0065] The transmission channel 101 is a linear conveying path formed by two parallel transmission belts 111a. Specifically, a synchronous belt transmission belt 111a can be used. The transmission belt 111a is driven by a motor or the like. The double-belt spacing matches the outer diameter of the syringe to achieve conveying. The limiting channel 102 is a guide structure composed of two limiting plates 111b. Specifically, a metal plate can be used to prevent the syringe from falling. The sliding channel 103 is a gravity chute formed by two inclined sliding plates 112a. Specifically, a metal plate with a smooth surface can be used. By adjusting the inclination angle, the syringe sliding speed can be adjusted. The transfer notches 1201 are arc-shaped grooves on the edge of the transfer disc 121. Specifically, they are U-shaped grooves with equal angles. The groove depth matches the diameter of the syringe to achieve positioning and receiving. The arc-shaped guide ring 122 is a semicircular guide arranged coaxially with the transfer disc 121. Specifically, a stainless steel arc-shaped guide rail can be used to guide the syringe to rotate into the transfer space 104.

[0066] Specifically, the syringes are clamped forward by the double transmission belt 111a in the transmission channel 101, and the limiting channel 102 formed by the limiting plate 111b synchronously restricts its lateral deviation. When the syringes reach the end of the transmission channel 101, the slide-down channel 103 makes them slide down along the inclined slide-down plate 112a to the position of the transfer gap 1201 by gravity. During the rotation of the transfer disc 121, the transfer gap 1201 is aligned with the outlet of the slide-down channel 103 in turn, and the syringes are received into the transfer gap 1201 one by one. The closed transfer space 104 formed by the arc-shaped guide ring 122 and the transfer gap 1201 forces the syringes to be stably transmitted by curved surface guidance during the rotation of the transfer disc 121. The transmission belt 111a can be arranged horizontally or obliquely, and the height difference between the transmission belt 111a and the slide-down channel 103 can be adjusted to adapt to the space layout of different production lines.

[0067] As shown in Figure 9 The transmission mechanism 13 includes a transmission frame 131 and a transmission chain belt 132, the transmission chain belt 132 is installed on the transmission frame 131, and the transmission chain belt 132 includes a plurality of limiting seats 133, and the limiting seats 133 are provided with limiting grooves 1301; the blanking mechanism 14 includes a horizontal slide rail 141, a horizontal slide 142, a fourth cylinder 143, a mounting seat 144, and a plurality of suction nozzles 145, the horizontal slide 142 slides on the horizontal slide rail 141, the fourth cylinder 143 is fixed on the horizontal slide 142, the fourth cylinder 143 drives the mounting seat 144 to move up and down, and the plurality of suction nozzles 145 are fixed on the mounting seat 144.

[0068] The transmission chain belt 132 is a closed loop conveying structure formed by connecting a plurality of link units in series, which can be made of engineering plastic or metal material, and the link units are connected by hinge shafts, each link unit is integrated with a limiting seat 133, the limiting seat 133 forms a limiting groove 1301 by injection molding or stamping process, the inner wall of the limiting groove 1301 matches the outer contour of the syringe, and is used to constrain the position deviation of the syringe during transmission. The horizontal slide rail 141 and the horizontal slide 142 refer to a sliding pair composed of a linear guide rail and a sliding block, which can be a ball linear guide rail, the slide rail is fixed on the frame by bolts, the sliding block is connected with the mounting plate of the fourth cylinder 143, and the suction nozzles 145 can be controlled to move in the horizontal direction. The suction nozzle 145 is a negative pressure suction head made of silica gel or rubber material, which can be designed as a bowl-shaped structure, and is connected with a vacuum generator through an air pipe inside, so as to grasp the syringe by negative pressure adsorption force, and avoid surface indentation caused by mechanical clamping.

[0069] Specifically, the transmission chain belt 132 is driven to circulate by the driving motor, and the injectors are sequentially fed into the clamping grooves of the limiting clamping seat 133. The geometric shape of the clamping groove is matched with the outer diameter of the injector, so that the injector can be kept in a flat state during the transmission process. In the feeding mechanism 14, the horizontal sliding seat 142 moves to a designated position above the transmission chain belt 132 along the horizontal sliding rail 141, the fourth cylinder 143 drives the mounting seat 144 to descend, so that the suction nozzle 145 contacts the top of the injector, and the vacuum generator is started to adsorb and fix the injector. Then the fourth cylinder 143 retracts, the horizontal sliding seat 142 moves to above the packaging station, and the vacuum release completes the accurate feeding of the injector. The parallel layout of multiple suction nozzles 145 enables multiple injectors to be transferred in a single action, improving the work efficiency.

[0070] As shown in Figure 10 The welding mechanism 24 includes a material supporting plate 241, a welding box 242, and a heating element 243. The heating element 243 is fixed in the welding box 242, and the heating element 243 and the material supporting plate 241 have a welding channel therebetween. The material supporting plate 241 is arc-shaped and the middle part of the material supporting plate 241 is higher than the two ends.

[0071] The material supporting plate 241 is a support component for carrying the base material and the auxiliary material, which can be formed by stamping a stainless steel plate into a curved surface structure with a middle part protruding upward. The curved surface structure presents a continuous and smooth arc change in the longitudinal cross-section. The welding box 242 is a closed box structure for accommodating the heating element 243, which can be realized by a composite structure of double-layer metal plates with a heat insulation layer sandwiched therebetween. The internal space of the welding box 242 forms a heat conduction region with the lower surface of the material supporting plate 241. The heating element 243 is an element for generating heat, which can be realized by an array of resistance wires or carbon fiber heating sheets, and is installed on the inner wall of the welding box 242 by a fixing support. The welding channel is a path region for the base material and the auxiliary material to be heated and melted during the welding process, and the channel spacing can be controlled by adjusting the vertical distance between the material supporting plate 241 and the heating element 243.

[0072] Specifically, the closed design of the welding box 242 limits the heat generated by the heating element 243 in a fixed space, avoiding heat loss and reducing external environmental interference. The arc-shaped structure of the material supporting plate 241 forms a curved surface shape with the middle part being high and the two sides being low during the conveying process of the base material. When the base material and the auxiliary material enter the welding channel, the arc surface guides the melted material to uniformly extend along the tangent direction of the curved surface. The pre-stress generated by the curved surface shape can offset the linear deformation caused by the thermal expansion of the material, preventing wrinkles or cracks from occurring at the sealing interface.

[0073] As shown in Figure 11As shown, the cutting mechanism 31 includes a cutting frame 311, a sliding frame 312, a first driving member 313, a cutting seat 314, a second driving member 315, a pushing seat 316, and a cutting knife 317. The cutting frame 311 and the second driving member 315 are fixed on the cabinet, the sliding frame 312 is in sliding connection with the cutting frame 311, the first driving member 313 is fixed on the sliding frame 312, the cutting seat 314 is fixed on the output end of the first driving member 313, the cutting knife 317 is installed on the pushing seat 316, the pushing seat 316 is fixed on the output end of the second driving member 315, the sliding frame 312 drives the first driving member 313 to reciprocate in the direction of transverse product cutting, the first driving member 313 drives the cutting seat 314 to move towards the product, and the second driving member 315 drives the cutting knife 317 to move towards the product, and the cutting knife 317 is correspondingly matched with the cutting seat 314.

[0074] The cutting frame 311 is a support structure fixed on the cabinet, which provides a stable sliding track for the sliding frame 312. The sliding frame 312 is a moving part in sliding cooperation with the cutting frame 311 and is used to fix the first driving member 313. Specifically, a linear guide rail and a sliding block combination structure can be adopted to achieve the transverse movement range covering the entire width of the product cutting area. The first driving member 313 is a power device driving the cutting seat 314 to reciprocate up and down, which can be realized by a pneumatic push rod or an electric linear module, and the displacement height of the cutting seat 314 is controlled by vertical movement. The cutting seat 314 includes a seat body and a rotating wheel, the seat body is fixed on the output end of the second driving member, and the rotating wheel is in the shape of an I or an inverted 8. The cutting knife 317 is a cutter for cutting, which can be realized by a hard alloy blade, and the edge shape is matched with the transverse cutting line of the product. The second driving member 315 is a power device driving the cutting knife 317 to reciprocate up and down, which can be realized by a pneumatic push rod or an electric linear module, and the displacement height of the cutting knife 317 is controlled by vertical movement.

[0075] Specifically, the cutting frame 311 is fixed on the top of the cabinet by a rigid connection method to form a stable work platform. The sliding frame 312 moves transversely along the linear guide rail on the cutting frame 311 to drive the first driving member 313 and the cutting seat 314 to move transversely.

[0076] When cutting, the second driving member 315 pushes the cutting knife 317 to move upward until the cutting knife 317 approaches or touches the base material. Then the sliding frame 312 drives the first driving member 313 to move, and when the sliding frame 312 moves to the target cutting position, the first driving member 313 starts and pushes the cutting seat 314 to move vertically downward, and the cutting seat 314 presses the packaging material formed by the base material and the auxiliary material towards the cutting knife 317. After the sliding frame 312 drives the cutting seat 314 to move transversely, the cutting seat 314 and the cutting knife 317 complete the transverse cutting of the packaging material.

[0077] After cutting is completed, the second driving member 315 drives the cutting knife 317 to reset, and the first driving member 313 drives the cutting seat 314 to reset. The cutting mode realizes continuous horizontal cutting operation through the composite action of horizontal movement and vertical cutting. When the rotating wheel on the cutting seat 314 cooperates with the cutting knife 317, the cutting edge of the cutting knife 317 extends into the middle space of the rotating wheel, at this time, the two ends of the rotating wheel press down on the packaging material, and then the clamping and fixing of the conveying assembly on the base material are cooperated, so as to realize stable cutting of the packaging material.

[0078] As shown in Figure 12 and Figure 13 , the material distribution mechanism 32 includes a pressing assembly 321, a material distribution assembly 322, and two sets of edge distribution assemblies 323, the two sets of edge distribution assemblies 323 are respectively arranged on both sides of the material distribution assembly 322 and correspond to the two collecting assemblies 332 respectively, the pressing assembly 321 includes a pressing frame 321a fixed on the cabinet, a pressing shaft 321b rotationally connected with the pressing frame 321a, and a pressing roller 321c sleeved on the pressing shaft 321b, the material distribution assembly 322 includes a guide cover 3221 fixed on the cabinet and a plurality of material distribution pieces 3222, the plurality of material distribution pieces 3222 are evenly arranged in the direction of finished product cutting, the material distribution piece 3222 includes a spring 301 fixed on the cabinet, a material distribution seat 302 connected with the spring 301, and a material distribution knife wheel 303 rotationally connected with the material distribution seat 302, the guide cover 3221 is provided with a plurality of guide holes 304 for the material distribution seat 302 to pass through, the material distribution knife wheel 303 corresponds to the pressing roller 321c, and the edge distribution assembly 323 includes an edge distribution seat 323a fixed on the cabinet and an edge distribution knife wheel 323b installed on the edge distribution seat 323a, the edge distribution knife wheel 323b corresponds to the end of the pressing roller 321c.

[0079] The pressing roller 321c is a cylindrical component rotationally connected with the pressing shaft 321b and the pressing frame 321a, which can be realized by a steel roller body with a rubber layer on the surface, and its function is to apply constant pressure to the packaging material through rotary contact to keep the material flat. The material distribution knife wheel 303 is a circular cutting tool installed on the material distribution seat 302, which can be realized by a hard alloy blade and a bearing support structure, and its function is to realize self-adaptive adjustment of the longitudinal cutting depth through cooperation with the pressing roller 321c. The guide hole 304 is a through hole provided on the guide cover 3221, which can be realized by a rectangular or circular hole structure, and its function is to prevent the material distribution knife wheel 303 from shifting horizontally by restricting the movement track of the material distribution seat 302. The edge distribution knife wheel 323b is an edge cutting tool arranged on the edge distribution seat 323a, which can be realized by a double-blade knife and an adjustable mounting seat, and its function is to complete the waste edge cutting through the corresponding position of the end of the pressing roller 321c.

[0080] Specifically, in the longitudinal slitting process, the pressure roller 321c applies uniform pressure to the packaging material through rotary contact, and the slitting knife wheel 303 maintains constant contact pressure with the pressure roller 321c under the action of the spring 301, so that the cutting depth is automatically adjusted according to the material thickness. The guide hole 304 of the guide cover 3221 guides the slitting seat 302 to move in the preset direction, ensuring the straightness of the cutting track of the slitting knife wheel 303. The side trimmer wheel 323b is arranged corresponding to the end of the pressure roller 321c, which separates the two side trimmings from the finished product at the same time of longitudinal slitting. The two groups of side trimming assemblies 323 correspond to the two collection assemblies 332 respectively, so that the waste edges are collected by the collection wheels 332b through independent paths. The uniform arrangement of the slitting knife wheel 303 along the cutting direction can realize the synchronous completion of multi-channel slitting operation, and the slitting seat 302 connected by the spring 301 can absorb the cutting vibration to maintain the stable contact between the slitting knife wheel 303 and the pressure roller 321c.

[0081] As Figure 12 described, the waste edge collection mechanism 33 includes a fixed frame 331 and two collection assemblies 332 placed on the fixed frame 331. The collection assembly 332 includes a motor 332a, a collection wheel 332b, a first traction wheel 332c, a second traction wheel 332d, and an adjusting member 332e. The motor 332a is fixed to the fixed frame 331, and the collection wheel 332b is connected to the output end of the motor 332a.

The adjusting wheel 3004 is placed between the first traction wheel 332c and the second traction wheel 332d.

[0082] The fixed frame 331 is a support frame for bearing the collection assembly 332, which can be implemented by a welded steel frame or an aluminum alloy profile frame. Its function is to provide an installation reference for the collection wheel 332b, the traction wheel, and the adjusting member 332e. The collection assembly 332 is a functional unit that independently completes the waste edge winding, which can realize synchronous processing of waste edges through bidirectional symmetric arrangement. Its function is to improve the waste edge processing efficiency through a double-station structure. The adjusting member 332e is a mechanical device for dynamically controlling the tension of the waste edge, which can realize self-adaptive adjustment of the tension through the sliding of the counterweight sliding block 3003 on the guide column 3002. Its function is to replace the traditional sensor feedback control through gravity balance, avoiding the rupture or accumulation of waste edges due to tension fluctuations.

[0083] Specifically, the motor 332a drives the collection wheel 332b to rotate to actively recover the scrap edge, and the first traction wheel 332c and the second traction wheel 332d form a scrap edge transmission path to avoid deviation of the scrap edge during transmission. The position of the adjusting wheel 3004 is dynamically adjusted by the sliding of the counterweight sliding block 3003 on the guide column 3002: when the scrap edge tension increases, the adjusting wheel 3004 moves upward under the tension, and the counterweight sliding block 3003 moves downward along the guide column 3002 to offset the tension; when the scrap edge tension decreases, the counterweight sliding block 3003 drives the adjusting wheel 3004 to move downward due to gravity to tighten the scrap edge. The process realizes self-balancing of the tension through mechanical linkage, without relying on external power or electronic control systems.
