Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and more specifically, it relates to a dual-module cutter and packaging machine. Background Technology

[0002] In the modern packaging industry, especially in scenarios involving automated feeding of bagged materials, such as food processing, pharmaceutical production, and chemical ingredient mixing, bag cutting and feeding machines play a crucial role. Their core function is to quickly respond and accurately, efficiently, and cleanly cut open packaging bags and then feed the contents into designated workstations.

[0003] In the existing technology, current bag cutting and feeding machines mainly include bag feeding machines that use a rotary cutting mechanism and bag feeding machines that use a straight cutting mechanism. Rotary cutting bag feeding machines have smooth cutting and are not prone to jamming, making them more suitable for cutting soft, tough, and sticky materials. However, they achieve the cutting effect by rotating and contacting two blades, and the distance between the two blades is difficult to control. This can lead to situations where the blades cannot be effectively cut when they are too far apart, and when they are too close, the blades can wear out and chip too quickly. Furthermore, replacing the blades is also relatively complicated.

[0004] Straight-cutting bag feeders have stronger cutting capabilities than rotary-cutting bag feeders and are more suitable for cutting hard and brittle materials. By keeping the feeder as perpendicular as possible to the bag, the cutting effect can be guaranteed. However, due to the reciprocating motion of the blades, the vibration generated by the equipment during high-speed operation may affect its cutting accuracy, resulting in misaligned cuts or incomplete cuts, which affects production efficiency. Therefore, the two mainstream bag feeder types currently have poor flexibility and are difficult to meet the needs of actual production, making it difficult to maximize production efficiency.

[0005] Therefore, a dual-module cutter and packaging machine is needed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a dual-module cutter and packaging machine to solve the problems mentioned in the background art.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A dual-module cutter bag-making machine includes a frame and a conveyor belt. At both ends of the frame are a roller cutter mechanism and a straight cutter mechanism, both located above the conveyor belt. Each roller cutter mechanism and straight cutter mechanism includes an intermediate pool, a traction assembly, a conveying assembly, and a slitting assembly. The slitting assembly of the rotary cutting mechanism includes a pressure spring and two rotary cutting shafts. The two rotary cutting shafts are connected in a driving relationship, and one of the rotary cutting shafts is driven by a motor. The pressure spring is mounted on the other rotary cutting shaft. Several rotary cutting blades arranged in a circular array are detachably connected to both rotary cutting shafts. The slitting assembly of the straight cutting mechanism includes a fixed cutter, an active cutter, a limiting member, and a transmission member. Both the fixed cutter and the active cutter have toothed surfaces. The limiting member is located below the fixed cutter, and the active cutter slides between the fixed cutter and the limiting member. The transmission member is rotatably connected to the end of the active cutter away from the fixed cutter. The drive source at the other end of the transmission member is also a motor, and it is detachably connected to the output shaft of the motor.

[0008] The technical solution of this utility model is further configured as follows: one end of each of the two rolling cutting shafts is provided with a transmission gear and the two transmission gears mesh; both ends of one rolling cutting shaft are provided with mounting plates and their ends are respectively rotatably connected to the two mounting plates; and the pressure spring is disposed on the two mounting plates.

[0009] The technical solution of this utility model is further configured as follows: the conveying component of the rolling cutter mechanism includes a guide rail, clamping rollers and detection sensors. The clamping rollers are distributed on the top and bottom surfaces at both ends of the guide rail, and the detection sensors are distributed on the top and bottom surfaces in the center of the guide rail. The guide rail has notches corresponding to the clamping rollers and the detection sensors.

[0010] The technical solution of this utility model is further configured as follows: the frame is provided with a plurality of track supports, the track supports are staggered with the clamping rollers and the detection sensors, the track supports are provided with through slots through which they pass, the guide track includes two track components connected to the through slots by bolts, and the notch is formed by the distance between the two track components.

[0011] The technical solution of this utility model is further configured as follows: the driving source of one of the clamping rollers located below the guide rail is a motor and it is connected to the other clamping rollers below the guide rail through a synchronous belt. All the clamping rollers are provided with linkage gears on their shafts, and the linkage gears on the two corresponding clamping rollers mesh with each other.

[0012] The technical solution of this utility model is further configured such that: both sides of the fixed cutter are connected to the two limiting members respectively through connecting plates, and the limiting members are rollers rotatably connected to the bottom end of the connecting plates and abut against the bottom surface of the active cutter.

[0013] The technical solution of this utility model is further configured as follows: the conveying component of the straight cutting knife mechanism includes a drive wheel, a follower wheel and two guide clamps. Both guide clamps are provided with grooves and through holes. The ends of the drive wheel and the follower wheel facing each other are respectively located in the two grooves. A detection sensor is also provided at the through hole.

[0014] The technical solution of this utility model is further configured as follows: the traction component of the rolling cutter mechanism includes a plurality of traction rollers, and the traction component of the straight cutter mechanism includes a plurality of traction brackets, with two conveying rollers slidably connected on each traction bracket.

[0015] The technical solution of this utility model is further configured as follows: a tensioning roller and a conveying roller are provided at the intermediate pool, the conveying roller is rotatably connected to the top of the intermediate pool, and the tensioning roller is located inside the intermediate pool.

[0016] The technical solution of this utility model is further configured such that: the rolling cutter mechanism also includes a transport component disposed at the end of its slitting component, the transport component includes a synchronous toothed belt and a transport roller, the synchronous toothed belt is connected to the transport roller in a transmission manner and its drive source is the same motor as the drive source of the rolling cutter shaft.

[0017] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: By installing a roller cutter mechanism and a straight cutter mechanism on the frame, this packaging machine can perform dual-module cutting, which provides high flexibility to adapt to most materials and packaging formats, ensuring the cutting effect of various materials. For example, when multiple different material packets need to be dispensed onto a single noodle cake, such as instant noodles, the roller cutter mechanism and the straight cutter mechanism can be activated simultaneously to maximize production efficiency. This allows the packaging machine to not only perform targeted cutting but also to operate simultaneously.

[0018] By installing pressure springs on the mounting plates at both ends of a roller cutting shaft, pressure is applied to the roller cutting shaft in a constant direction toward the other roller cutting shaft, bringing the roller cutting blades on the two roller cutting shafts closer together to ensure cutting pressure during roller cutting, thereby achieving a stable material cutting effect. In addition, the pressure springs can also buffer the vibrations generated during the operation of the bagging machine to avoid the impact of vibration on the cutting effect and ensure the quality of the finished product. The roller cutting blades on the roller cutting shaft can also be quickly replaced to adapt to different cutting effect requirements.

[0019] By mounting rollers at the bottom of the connecting plate as a limiting element, the active cutter can only slide between the fixed cutter and the limiting element, and the limiting element also rotates accordingly to reduce friction and make the sliding of the active cutter smoother. This method restricts the active cutter's activity space as much as possible to achieve stable slitting and improve slitting accuracy. The transmission component is connected to the motor, and together with the limiting element and the fixed cutter's restriction on the active cutter, it converts the rotation of the motor shaft into the sliding cutting motion of the active cutter. The motor is used as the power source to ensure the efficiency of the slitting work. Attached Figure Description

[0022] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model. Example

[0023] refer to Figure 1 and Figure 2 As shown, this utility model provides a dual-module cutter baggage machine, including a frame 1 and a conveyor belt 2. The two ends of the frame 1 are respectively provided with a roller cutter mechanism and a straight cutter mechanism, both located above the conveyor belt 2. Both the roller cutter mechanism and the straight cutter mechanism include an intermediate pool 3, a traction component, a conveying component and a slitting component. The intermediate pool 3 is provided with a tension roller 26 and a conveying roller 27. The conveying roller 27 is rotatably connected to the top of the intermediate pool 3, and the tension roller 26 is located inside the intermediate pool 3.

[0024] The material can be selected to enter the intermediate pool 3 of the rotary cutter mechanism or the straight cutter mechanism, and after passing the bottom end of the tension roller 26, it passes around the top end of the conveyor roller 27 and enters the corresponding traction component. During this process, the tension roller 26 adjusts the tension of the material by its weight. Specifically, when the tension of the material belt is insufficient, the tension roller 26 moves downward in the intermediate pool 3 under its own weight to tighten the material belt. When the tension is sufficient, the material belt drives the tension roller 26 to move upward in the intermediate pool 3.

[0025] refer to Figures 1 to 4 As shown, the traction component of the rotary cutter mechanism includes several traction rollers 23, and the conveying component of the rotary cutter mechanism includes a guide rail 13, clamping rollers 14, and detection sensors 15. The clamping rollers 14 are distributed on the top and bottom surfaces at both ends of the guide rail 13, and the detection sensors 15 are distributed on the top and bottom surfaces in the center of the guide rail 13. The guide rail 13 has notches corresponding to the clamping rollers 14 and the detection sensors 15. The frame 1 is provided with several track supports 16, which are staggered with the clamping rollers 14 and the detection sensors 15. The track supports 16 have through slots that pass through them. The guide rail 13 includes two track components that are bolted to the through slots. The notches are formed by the distance between the two track components. The drive source of one of the clamping rollers 14 located below the guide rail 13 is a motor, which is connected to the other clamping rollers 14 below the guide rail 13 via a synchronous belt 17. All the clamping rollers 14 have linkage gears 18 on their shafts, and the linkage gears 18 on the two corresponding clamping rollers 14 mesh.

[0026] After being conveyed by several traction rollers 23 of the rotary cutter mechanism, the material belt enters its conveying assembly and moves within the inclined guide rail 13. At this time, the output shaft of a motor rotates, driving the linkage gear 18 and the clamping roller 14 connected to it to rotate. The synchronous belt 17 causes the clamping rollers 14 below the other guide rails 13 to rotate, and the linkage gear 18 causes the corresponding clamping rollers 14 above these clamping rollers 14 to rotate together, thereby achieving the effect of conveying the material belt within the guide rail 13. At the same time, the detection sensor 15 detects the material belt at the guide rail 13 to obtain the current speed of the material belt. Moreover, the position of the two track components on the track support 16 can be adjusted according to the width of the material belt to adapt to the cutting requirements of material belts of different widths.

[0027] refer to Figure 3 and Figure 4 As shown, the slitting assembly of the rotary cutting mechanism includes a pressure spring 4 and two rotary cutting shafts 5. The two rotary cutting shafts 5 are connected by a drive, and the drive source of one of the rotary cutting shafts 5 is a motor. The pressure spring 4 is set on the other rotary cutting shaft 5. Several rotary cutting cutters 6 arranged in a ring array are detachably connected to both rotary cutting shafts 5 by bolts. One end of each rotary cutting shaft 5 is provided with a drive gear 11 and the two drive gears 11 mesh. Both ends of one rotary cutting shaft 5 are provided with mounting plates 12 and their ends are rotatably connected to the two mounting plates 12 respectively. The pressure spring 4 is set on the two mounting plates 12.

[0028] By installing pressure springs 4 on the mounting plates 12 at both ends of one rolling cutting shaft 5, the pressure springs 4 can not only apply pressure to the rolling cutting shaft 5 towards the other rolling cutting shaft 5, but also bring the rolling cutting blades 6 on the two rolling cutting shafts 5 closer together to ensure the cutting pressure during rolling cutting, thereby achieving a stable material cutting effect. In addition, the pressure springs 4 can also buffer the vibration generated during the operation of the bagging machine to avoid the impact of vibration on the cutting effect, ensuring the quality of the finished product while reducing the noise generated by vibration. The rolling cutting blades 6 on the rolling cutting shaft 5 can also be quickly replaced to adapt to different cutting effect requirements, and can be replaced in time when worn. When the motor is working, the output shaft of the motor rotates, driving the rolling cutting shaft 5 and the transmission gear 11 connected to it to rotate. At this time, the transmission gear 11 drives the other transmission gear 11 to rotate, thereby achieving the effect of synchronous rotation of the two rolling cutting shafts 5, so that the corresponding rolling cutting blades 6 cut the material strip.

[0029] refer to Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, the rolling cutter mechanism also includes a transport component located at the end of its slitting component. The transport component includes a synchronous toothed belt 28 and a transport roller 29. The synchronous toothed belt 28 is connected to the transport roller 29, and its drive source is the same motor as the drive source of the rolling cutter shaft 5. The synchronous toothed belt 28, the transport roller 29, and the motor are all driven by gear sets. Both ends of the synchronous toothed belt 28 are provided with synchronous pulleys 31.

[0030] This method enables the motor to not only drive the two cutting shafts 5 to rotate synchronously when started, but also to drive a synchronous pulley 31 and a gear set to rotate, thereby causing the synchronous toothed belt 28 and the conveyor roller 29 behind the two cutting shafts 5 to rotate, and transporting the material cut by the two cutting shafts 5 to the conveyor belt 2.

[0031] refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the traction component of the straight cutting mechanism includes several traction brackets 24, and two conveying rollers 25 are slidably connected to each traction bracket 24. The conveying component of the straight cutting mechanism includes a drive wheel 20, a follower wheel 21, and two guide plates 22. The two guide plates 22 are provided with grooves and through holes. The ends of the drive wheel 20 and the follower wheel 21 facing each other are located in the two grooves respectively. A detection sensor 15 is also provided at the through hole. The drive source of the drive wheel 20 is also a motor, and its surface is uniformly provided with several protrusions for increasing friction.

[0032] After passing the tension roller 26 and the conveyor roller 27, the material belt enters the two conveyor rollers 25 on the traction bracket 24. The conveyor rollers 25 are connected to the traction bracket 24 by screws and wing nuts, which allows the spacing between the two conveyor rollers 25 to be adjusted according to the width of the material belt. After passing the traction component of the straight cutter mechanism, the material belt enters the corresponding conveyor component, that is, between the two guide clamps 22. At this time, the drive wheel 20 rotates and drives the material belt to continue to move downward. The follower wheel 21 rotates after contacting the surface of the material belt. The detection sensor 15 detects the speed of the material belt when it passes the guide clamp 22.

[0033] refer to Figure 5 and Figure 6As shown, the slitting assembly of the straight cutting mechanism includes a fixed cutter 7, an active cutter 8, a limiting member 9, and a transmission member 10. Both the fixed cutter 7 and the active cutter 8 have toothed surfaces. The limiting member 9 is located below the fixed cutter 7, and the active cutter 8 slides between the fixed cutter 7 and the limiting member 9. The transmission member 10 is rotatably connected to the end of the active cutter 8 away from the fixed cutter 7. The drive source at the other end of the transmission member 10 is also a motor, and it is detachably connected to the output shaft of the motor. Both sides of the fixed cutter 7 are connected to the two limiting members 9 respectively through connecting plates 19. The limiting member 9 is a roller rotatably connected to the bottom end of the connecting plate 19 and abuts against the bottom surface of the active cutter 8. The end of the rotating shaft of the limiting member 9 that extends out of the connecting plate 19 is also provided with a tension spring 30, and the other end of the tension spring 30 is connected to the fixed cutter 7.

[0034] By installing rollers at the bottom of the connecting plate 19 as limiting members 9, the active cutter 8 can only slide between the fixed cutter 7 and the limiting member 9, and the limiting member 9 will also rotate accordingly to reduce friction and make the sliding of the active cutter 8 smoother. This method restricts the active cutter 8's activity space as much as possible to achieve stable cutting and improve cutting accuracy. The transmission member 10 is connected to the motor and, together with the limiting member 9 and the fixed cutter 7, restricts the active cutter 8 to convert the rotation of the motor shaft into the sliding cutting motion of the active cutter 8. The motor is used as the power source to ensure the efficiency of the cutting work. The tension spring 30 is used to buffer vibration and always apply an upward force to the limiting member 9 to prevent it from loosening.

[0035] refer to Figures 1 to 8 As shown above, this packaging machine, by setting a roller cutter mechanism and a straight cutter mechanism on the frame 1, enables dual-module group cutting, providing high flexibility to adapt to most materials and packaging forms, ensuring the cutting effect of various materials. Moreover, for example, when multiple different material packets need to be dispensed onto a single noodle cake, such as instant noodles, the roller cutter mechanism and the straight cutter mechanism can be activated simultaneously to maximize production efficiency. Thus, this packaging machine can not only perform targeted cutting but also operate simultaneously.

All technical solutions that fall within the concept of the present utility model are within the protection scope of the present utility model.
