Description

Technical Field

[0001] The present invention relates to the technical field of packaging machinery, and more particularly to a double-module cutter bag-dropping machine. Background Art

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

[0003] In the prior art, current bag cutting and delivering machines mainly include those using a rolling cutter mechanism and those using a straight cutter mechanism. The rolling cutter delivering machine has smooth cutting and is not prone to material jamming, and is more suitable for cutting soft, tough, and sticky materials. However, it achieves the cutting effect by rotating and contacting two cutters, and the distance between the two cutters is difficult to control, resulting in an ineffective cutting when the cutters are too far away, and a rapid wear and chipping of the two cutters when the cutters are too close, and the replacement of the cutters is also relatively complicated.

[0004] The straight-cutting bag-dispensing machine has a stronger cutting capability than the rolling-cutting bag-dispensing machine and is more suitable for cutting hard and brittle materials. It ensures the cutting effect by keeping the blade as vertical as possible to the bag. However, it is limited by the reciprocating motion of the blade. When the equipment runs at high speed, the vibration generated by the equipment may affect its cutting accuracy, resulting in crooked or uninterrupted cutting, affecting production efficiency. Therefore, the two mainstream bag-dispensing machines currently have poor flexibility and are difficult to meet the needs of actual production and maximize production efficiency.

[0022] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention. Example

[0023] refer to Figure 1 and Figure 2As shown, the present invention provides a dual-module cutter bagging machine, including a frame 1 and a conveyor belt 2. The two ends of the frame 1 are respectively provided with a rolling cutter mechanism and a straight cutter mechanism, both of which are located above the conveyor belt 2. The rolling cutter mechanism and the straight cutter mechanism both include an intermediate pool 3, a traction component, a conveying component and a slitting component. A tensioning roller 26 and a conveying roller 27 are provided at the intermediate pool 3. The conveying roller 27 is rotatably connected to the top of the intermediate pool 3, and the tensioning roller 26 is located in the intermediate pool 3.

[0024] The material can be selected to enter the intermediate pool 3 of the rolling cutter mechanism or the straight cutter mechanism according to the situation, and then pass through the bottom end of the tensioning roller 26 and around the top end of the conveying roller 27 to enter the corresponding traction component. During this process, the tensioning roller 26 adjusts the tension of the material by its weight. Specifically, when the tension of the material belt is insufficient, the tensioning roller 26 moves downward in the intermediate pool 3 under its gravity, tightening the material belt. When the tension is sufficient, the material belt drives the tensioning roller 26 to move upward in the intermediate pool 3.

[0025] refer to Figures 1 to 4 As shown, the traction assembly of the rolling cutter mechanism includes several traction rollers 23, and the conveying assembly of the rolling cutter mechanism includes a guide rail 13, a pinching roller 14 and a detection sensor 15. The pinching roller 14 is distributed on the top and bottom surfaces at both ends of the guide rail 13, and the detection sensor 15 is distributed on the top and bottom surfaces in the center of the guide rail 13. A notch corresponding to the pinching roller 14 and the detection sensor 15 is provided on the guide rail 13. A plurality of rail brackets 16 are provided on the frame 1. The rail brackets 16 are staggered with the pinching roller 14 and the detection sensor 15. A through groove is provided on the rail bracket 16 for passing through it. The guide rail 13 includes two rail components connected at the through groove by bolts. The notch is formed by the distance between the two rail components. The driving source of one of the pinching rollers 14 located below the guide rail 13 is a motor and is connected to the remaining pinching rollers 14 below the guide rail 13 through a synchronous belt 17. A linkage gear 18 is provided on the rotating shaft of all the pinching rollers 14, and the linkage gears 18 on the two corresponding pinching rollers 14 above and below are engaged.

[0026] After being conveyed by several traction rollers 23 of the rolling cutter mechanism, the material belt enters its conveying assembly and moves in the inclined guide track 13. At this time, the output shaft of a motor rotates to drive the linkage gear 18 and the pinch roller 14 connected to it to rotate. The synchronous belt 17 rotates the pinch rollers 14 below the remaining guide tracks 13, and the linkage gear 18 rotates the corresponding pinch rollers 14 above these pinch rollers 14 to achieve the effect of conveying the material belt in the guide track 13. At the same time, the detection sensor 15 detects the material belt at the guide track 13 to obtain the current speed of the material belt, and can adjust the position of the two track components on the track bracket 16 according to the width of the material belt, so as to adapt to the slitting requirements of material belts of different widths.

[0027] refer to Figure 3 and Figure 4 As shown, the slitting assembly of the rolling cutter mechanism includes a pressure spring 4 and two rolling cutter shafts 5. The two rolling cutter shafts 5 are transmission connected and the driving source of one of the rolling cutter shafts 5 is a motor. The pressure spring 4 is arranged on the other rolling cutter shaft 5. The two rolling cutter shafts 5 are detachably connected with a plurality of rolling cutter tools 6 distributed in a ring array by bolts. One end of the two rolling cutter shafts 5 is provided with a transmission gear 11 and the two transmission gears 11 are meshed. Both ends of a rolling cutter shaft 5 are provided with a mounting plate 12 and its two ends are respectively rotatably connected in the two mounting plates 12. The pressure spring 4 is arranged on the two mounting plates 12.

[0028] By arranging pressure springs 4 on the mounting plates 12 at both ends of a rolling cutting shaft 5, it is possible not only to apply pressure to the rolling cutting shaft 5 always toward the other rolling cutting shaft 5, so that the rolling cutting tools 6 on the two rolling cutting shafts 5 are close to each other to ensure the cutting pressure during rolling cutting, thereby achieving the effect of stable cutting of materials, but also the pressure springs 4 can buffer the vibration generated when the bag throwing machine is working, to avoid the influence of vibration on the cutting effect, to ensure the quality of the finished product while reducing the noise generated by vibration, and the rolling cutting tools 6 on the rolling cutting shaft 5 can also be quickly replaced to meet 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 thereto to rotate. At this time, the transmission gear 11 drives the other transmission gear 11 to rotate, thereby achieving the effect of making the two rolling cutting shafts 5 rotate synchronously, so that the corresponding rolling cutting tools 6 cut the material belt.

[0029] refer to Figure 3 、 Figure 4 、 Figure 7 and Figure 8 As shown, the rolling cutter mechanism also includes a transport component arranged at the end of its slitting component, and the transport component includes a synchronous toothed belt 28 and a transport roller 29. The synchronous toothed belt 28 is transmission-connected to the transport roller 29 and its driving source is the same motor as the driving source of the rolling cutter shaft 5. The synchronous toothed belt 28 and the transport roller 29 and the motor are all transmitted through a gear set, and synchronous pulleys 31 are provided at both ends of the synchronous toothed belt 28.

[0030] In this way, the start-up of the motor can not only drive the two rolling shafts 5 to rotate synchronously, but also drive a synchronous pulley 31 and a gear set to rotate, thereby rotating the synchronous toothed belt 28 and the transport roller 29 behind the two rolling shafts 5, and transporting the materials cut out by the two rolling shafts 5 to the conveyor belt 2.

[0031] refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6As shown, the traction assembly of the straight cutter mechanism includes several traction brackets 24, each of which is slidably connected to two conveying rollers 25. The conveying assembly of the straight cutter mechanism includes a driving wheel 20, a driven wheel 21 and two guide splints 22. The two guide splints 22 are both provided with grooves and through holes. The ends of the driving wheel 20 and the driven wheel 21 facing each other are respectively located in the two grooves. A detection sensor 15 is also provided at the through hole. The driving source of the driving wheel 20 is also a motor and its surface is evenly provided with a plurality of protrusions for increasing friction.

[0032] After the material belt passes through the tensioning roller 26 and the conveying roller 27, it enters the two conveying rollers 25 on the traction bracket 24. The conveying rollers 25 are connected to the traction bracket 24 by screws and butterfly nuts, so that the distance between the two conveying rollers 25 can be adjusted according to the width of the material belt. After passing through the traction component of the straight cutting mechanism, the material belt enters the corresponding conveying component, that is, enters between the two guide splints 22. At this time, the driving wheel 20 rotates to drive the material belt to continue moving downward. After the driven wheel 21 contacts the surface of the material belt, it rotates accordingly. The detection sensor 15 detects the speed of the material belt when passing through the guide splint 22.

[0033] refer to Figure 5 and Figure 6 As shown, the slitting assembly of the straight cutting knife mechanism includes a fixed tool 7, an active tool 8, a limiting member 9 and a transmission member 10. The fixed tool 7 and the active tool 8 both have tooth surfaces. The limiting member 9 is located below the fixed tool 7 and the active tool 8 slides between the fixed tool 7 and the limiting member 9. The transmission member 10 is rotatably connected to the end of the active tool 8 away from the fixed tool 7. The driving source of the other end of the transmission member 10 is also a motor and is detachably connected to the output shaft of the motor. Both sides of the fixed tool 7 are respectively connected to the two limiting members 9 through a connecting plate 19. The limiting member 9 is a roller rotatably connected to the bottom end of the connecting plate 19 and is against the bottom surface of the active tool 8. The end of the rotating shaft of the limiting member 9 extending 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 tool 7.

[0034] By installing a roller at the bottom end of the connecting plate 19 as a limiting member 9, the active tool 8 can only slide between the fixed tool 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 tool 8 smoother. This method limits the activity space of the active tool 8 as much as possible to achieve stable slitting and improve the slitting accuracy. The transmission member 10 is connected to the motor and cooperates with the limiting member 9 and the fixed tool 7 to limit the active tool 8 to convert the rotation of the motor shaft into a sliding cutting motion of the active tool 8. The motor is used as a source of power to ensure the efficiency of the slitting work. The tension spring 30 is used to buffer vibration while always applying an upward force to the limiting member 9 to prevent it from loosening.

[0035] refer to Figures 1 to 8 As shown, in summary, the present bag throwing machine is provided with a rolling cutter mechanism and a straight cutter mechanism on the frame 1, so that the present bag throwing machine can be dual-module cutting, with high flexibility, to adapt to most materials and packaging forms as much as possible, to ensure the cutting effect of various materials, and for example, in the case of instant noodles and the need to throw a variety of different material packages on a piece of noodle, the rolling cutter mechanism and the straight cutter mechanism can be started at the same time to maximize the production and processing efficiency, so that the present bag throwing machine can not only perform targeted cutting, but also can be started together to work.

All technical solutions under the concept of the present invention belong to the scope of protection of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications without departing from the principle of the present invention should also be regarded as the scope of protection of the present invention.
