Description

Technical Field

[0001] This invention relates to the field of packaging bag manufacturing equipment technology, and in particular to a cutting component of a bag making machine. Background Technology

[0002] Packaging bags are containers widely used in product packaging, playing an important role in protecting products, facilitating carrying, promoting sales, and enhancing brand image.

[0003] Bag making typically uses continuous rolls or rectangular substrates as raw materials, which are conveyed through multiple processes before being finally formed and sealed. For example, during the conveying process, it is usually necessary to cut the edges of the raw materials. The cutting components of existing bag making machines mostly use relatively arranged blades and blade holders to complete the cutting. The size and shape of the cutting area formed by the blades are fixed. Faced with the production needs of different bag types, opening sizes, or packaging bags of different specifications, different cutting requirements can only be achieved by changing the cutting blades and blade holders. The changeover and debugging of the cutting components is time-consuming and the downtime is high, which significantly reduces the continuous production efficiency and multi-specification adaptability of the bag making machine.

[0004] Furthermore, once the cutting area of ​​existing cutting components is formed, it cannot be adjusted. Even when producing packaging bags of similar specifications, the entire cutting assembly still needs to be replaced, resulting in a large number of cutting spare parts, high inventory costs, and cumbersome disassembly and assembly. At the same time, conventional cutting structures cannot adapt to the actual working conditions on the production floor, such as fluctuations in substrate width and minor adjustments to bag size. This easily leads to unreasonable cutting allowances and bag size deviations, affecting not only the finished product qualification rate but also wasting raw materials. In addition, frequent replacement of cutting components can exacerbate the accumulation of assembly errors, affecting cutting consistency and cut quality, making it difficult to meet the high-efficiency and high-precision large-scale production needs of the packaging industry. Summary of the Invention

[0005] The purpose of this invention is to solve the technical problem that the cutting components of existing bag making machines cannot meet the cutting requirements of different bag types, different opening sizes, or different specifications of packaging bags.

[0006] To solve the above-mentioned technical problems, embodiments of the present invention disclose a cutting component of a bag making machine, including a cutting unit. The cutting unit includes a cutting tool and a cutting tool holder that are spaced apart on the frame of the bag making machine along the cutting direction and are opposite to each other in the cutting direction. At least one of the cutting tool and the cutting tool holder can move toward each other along the cutting direction.

[0007] Furthermore, the surface of the cutting tool facing the tool holder is provided with a cutting edge facing the tool holder. The cutting edge surrounds the cutting area on the cutting tool along the cutting direction, and the projected area of ​​the cutting area on the tool holder is adjustable.

[0008] Using the above technical solution, this cutting component can move towards each other along the cutting direction via at least one of the cutting blade and the blade holder, thereby achieving the cutting of the substrate between the cutting blade and the blade holder. Furthermore, since the projected area of ​​the cutting area formed by the blades on the blade holder is adjustable, it can adapt to the cutting needs of substrates of different sizes and specifications without changing the cutting blade and blade holder, significantly reducing downtime for bag making machines and improving the production efficiency and multi-specification applicability of the bag making machine.

[0009] Furthermore, the bag making machine does not require frequent replacement of the entire cutting unit, reducing the number of tool parts, simplifying the debugging and disassembly process, and avoiding assembly errors caused by multiple disassembly and assembly, thus ensuring the accuracy of the cutting position and the stability of the cutting edge quality.

[0010] In addition, the size of the cutting area can be flexibly adjusted according to on-site conditions such as the width of the substrate and the design size of the bag, optimizing the cutting allowance, reducing raw material waste, improving the finished product qualification rate, and better meeting the needs of high-precision large-scale bag production.

[0011] The embodiments of the present invention also disclose a cutting component of a bag making machine. The cutting component further includes an adjustment unit, which is connected to the cutting unit in a transmission manner and moves relative to the planar linkage cutter and the cutter holder perpendicular to the punching direction.

[0012] By adopting the above technical solution, the adjustment unit can accurately link the cutting tool and the tool holder to move relative to each other in a plane perpendicular to the cutting direction. This allows for precise and stable adjustment of the projected area of ​​the cutting zone on the tool holder, meeting the cutting requirements of the bag-making machine for different specifications of substrates. Compared to manual adjustment, this significantly improves the adjustment accuracy and efficiency of the cutting zone.

[0013] The present invention also discloses a cutting component of a bag making machine. The cutting component includes a plurality of cutting units spliced ​​together along a first direction, and two components of two adjacent cutting units located on the same side in the punching direction are connected together.

[0014] Furthermore, the adjustment unit is connected to at least a number of components on the same side of the cutting unit in the punching direction, and moves in conjunction with the multiple components on the same side of the punching direction along a plane perpendicular to the punching direction.

[0015] The first direction is perpendicular to the punching direction.

[0016] By adopting the above technical solution, the cutting area can be set more flexibly through multiple sets of cutting units. The adjustment unit can link multiple components of multiple cutting units located on the same side to move synchronously, so as to realize the overall unified adjustment of the projected area of ​​multiple cutting areas. In addition, the components on the same side of adjacent cutting units are connected to each other, which makes the overall rigidity stronger and less prone to vibration and displacement during high-speed punching. This effectively improves cutting stability and cut quality, and reduces defects such as burrs and misalignment.

[0017] The present invention also discloses a cutting component of a bag making machine, wherein in a plurality of cutting units, the blade holders and blades of the two outermost cutting units located in a first direction are located on different sides in the punching direction.

[0018] Furthermore, the adjustment unit moves at least a number of components of multiple cutting units located on the same side of the punching direction along the first direction.

[0019] By adopting the above technical solution, since the blade holders and blades of the two outermost cutting units are located on different sides in the punching direction, when the adjustment unit moves multiple components of multiple cutting units located on the same side of the punching direction along the first direction, the length of multiple cutting areas in the first direction can be adjusted to meet the cutting requirements of different widths.

[0020] The present invention also discloses a cutting component of a bag making machine, wherein the adjusting unit and multiple cutting units are connected in a transmission manner to multiple components located on both sides in the punching direction, and the multiple components on both sides move toward or away from each other in a first direction.

[0021] Compared to single-sided adjustment, the dual-sided adjustment of multiple components on both sides of the cutting direction, achieved by simultaneously linking the adjustment unit with the cutting unit, offers advantages such as a wider adjustment range and higher efficiency. It can quickly adapt to the cutting needs of substrates of varying specifications, from narrow to wide widths. Furthermore, the synchronous movement of the components on both sides, either facing or back to back, enables symmetrical adjustment of the projected area of ​​the cutting zone, ensuring the center position of the cutting zone remains stable and preventing center offset during adjustment. In addition, the adjustment unit is simultaneously connected to multiple components on both sides, eliminating the need for dedicated adjustment structures for the components on both sides of the cutting direction, thus facilitating the arrangement of the cutting components on the bag-making machine frame.

[0022] The present invention also discloses a cutting component for a bag making machine, the cutting component comprising two cutting units.

[0023] In this design, the cutting tool of one cutting unit and the cutting tool holder of another cutting unit are located on one side of the punching direction and are joined together to form a first cutting component, while the cutting tool holder of one cutting unit and the cutting tool of another cutting unit are located on the other side of the punching direction and are joined together to form a second cutting component.

[0024] Furthermore, on the first and second cutting components, the cutting edges of each tool extend along the first direction, and both ends of the first direction are bent and extended along the second direction respectively; and in the projection in the punching direction, the cutting edges extending along the first direction are aligned with each other, and the cutting edges at both ends are bent and extended toward the same side in the second direction.

[0025] Furthermore, the second direction is perpendicular to the first direction.

[0026] By employing the above technical solution, the cutting of a predetermined area of ​​substrate is achieved through the cooperation between the cutting tool on the first cutting member and the cutting tool holder on the second cutting member, and the cooperation between the cutting tool holder and the cutting edge on the second cutting member. Furthermore, the cutting edges on the second cutting member and the second cutting member extend along a first direction and are bent at both ends along a second direction. When the adjusting unit moves the first cutting member and the second cutting member relative to each other along the first direction, the cutting area enclosed by the first cutting member and the second cutting member can be changed.

[0027] The present invention also discloses a cutting component of a bag making machine, wherein a first cutting component is movably mounted on a first guide member extending along a first direction on a frame via a first mounting component, and a second cutting component is movably mounted on a second guide member extending along the first direction via a second mounting component.

[0028] Furthermore, the adjustment unit has two transmission parts that are respectively connected to the first mounting component and the second mounting component, and the first mounting component and the second mounting component move synchronously towards or away from each other in a first direction.

[0029] By adopting the above technical solution, the first and second guide members respectively guide and support the first and second cutting components, making the translational movement of each cutting component in the first direction smoother and preventing offset or jamming during adjustment, thus ensuring adjustment accuracy. Furthermore, the adjustment unit drives the first and second mounting components respectively through two transmission parts, enabling the first and second cutting components to move synchronously towards or away from each other, allowing for precise and symmetrical adjustment of the overall cutting width and cutting area size.

[0030] The present invention also discloses a cutting component of a bag making machine. The adjustment unit includes an adjustment drive and an intermediate transmission component disposed at the output end of the adjustment drive. The adjustment drive is disposed on the frame. The intermediate transmission component is connected to a first mounting component via a first transmission part and to a second mounting component via a second transmission part. The adjustment drive drives the intermediate transmission component and moves the first mounting component and the second mounting component synchronously in the same or opposite directions in a first direction.

[0031] Using the above technical solution, the adjustment unit is equipped with only one adjustment drive component, which has a simple and compact structure and is easy to arrange on the bag making machine. The adjustment drive component drives the intermediate transmission component, and the first and second installation components are linked by the first transmission part and the second transmission part respectively. This can ensure that the first installation component and the second installation component move at the same height, avoid problems such as inconsistent adjustment speed and position deviation, and significantly improve the size adjustment accuracy of the cutting area.

[0032] The present invention also discloses a cutting component of a bag making machine. The adjusting drive component is configured as an adjusting drive motor, and the intermediate transmission component is configured as a transmission belt assembly. A pair of transmission wheels of the transmission belt assembly are respectively sleeved on the ends of the first lead screw constituting the first transmission part and the second lead screw constituting the second transmission part. The screws of the first lead screw and the second lead screw have opposite screw directions. The first lead screw is drivenly connected to the first nut on the first mounting component, and the second lead screw is drivenly connected to the second nut on the second mounting component.

[0033] Furthermore, both the first guide member and the second guide member are configured as adjusting guide rails extending along the first direction, and the first mounting component and the second mounting component are slidably adapted to the corresponding adjusting guide rails.

[0034] By employing the above technical solution, the drive motor, in conjunction with the transmission belt assembly, simultaneously drives the first and second lead screws, which rotate in opposite directions. Utilizing the transmission characteristics of the lead screw and nut pair, the first and second mounting components automatically achieve synchronous translation towards or away from each other, thereby enabling accurate adjustment of the cutting area. Furthermore, the lead screw and nut pair possesses excellent self-locking properties, automatically locking the position of the cutting components after adjustment. This effectively resists vibration and impact during high-speed punching, preventing unexpected dimensional shifts in the cutting area and ensuring cutting stability during long-term continuous production.

[0035] The present invention also discloses a cutting component of a bag making machine. A punching guide extending along the punching direction is provided between a first mounting component and a corresponding first cutting component. A punching driving component is also provided on the first mounting component, and the punching driving component drives the first cutting component to move along the punching direction.

[0036] By employing the above technical solution, a punching guide extending along the punching direction is provided between the first mounting component and the first cutting component, ensuring that the cutter on the first cutting component and the cutter holder on the second cutting component maintain precise alignment throughout the punching process, thus avoiding defects such as chipped edges, burrs, and incomplete cuts caused by off-center loading. Furthermore, during the cutting process, the second cutting component on the second mounting component does not require an additional drive structure, which facilitates the compactness of the cutting components.

[0037] The present invention also discloses a cutting component of a bag making machine. The punching drive component includes a punching drive motor, a transmission disk, and a swing arm. The transmission disk is disposed at the output end of the punching drive motor. One end of the swing arm is eccentrically connected to the transmission disk, and the other end is hinged to the side of the first cutting component away from the second cutting component.

[0038] Furthermore, the blanking guide is configured as a blanking guide rail extending along the blanking direction.

[0039] By adopting the above technical solution, the transmission disk is rotated by the punching drive motor, and the rotary motion is converted into linear reciprocating motion of the first cutting component along the punching direction by the eccentrically connected swing arm. This transmission method is smooth and the power is transmitted directly, which can drive the first cutting component to perform continuous and regular punching action. It can be adapted to high-speed bag making conditions and can maintain a stable punching stroke and cutting force at high speed.

[0040] The present invention also discloses a cutting component of a bag making machine, wherein the cutting direction is vertical and the first cutting component is located above the second cutting component in the vertical direction.

[0041] Furthermore, a waste collection component is provided on the side of the frame next to the second cutting component, and a waste transfer component is provided between the waste collection component and the second cutting component. The waste transfer component can transfer the waste on the second cutting component to the waste collection component.

[0042] By adopting the above technical solution, by setting up a waste transfer component and a waste collection component next to the second cutting component, the cutting waste that falls on the second cutting component after punching can be transferred to the waste collection component in a timely manner, which effectively avoids the accumulation and jamming of waste at the cutting position, prevents waste from interfering with the base material conveying, bag forming and subsequent cutting operations, and ensures the continuous and smooth bag making process.

[0043] Furthermore, the punching direction is set to the vertical direction, and the first cutting component is located above the second cutting component. The cut waste can fall naturally onto the second cutting component below under the action of gravity. With the help of the waste transfer component, the waste can be transported more smoothly without the need for additional complex guide or lifting structures.

[0044] The present invention also discloses a cutting component of a bag making machine. The waste transfer component includes a waste discharge drive component, a waste discharge transmission component, and a waste discharge trolley. The waste discharge trolley is provided with an adsorption part and is slidably disposed on the waste discharge guide component. The first cutting component is provided with an avoidance groove adapted to the waste discharge trolley on one side of the blade. The waste collection component is a waste collection hopper.

[0045] Among them, the waste discharge drive can drive the waste discharge transmission component and link the waste discharge trolley to extend into the avoidance groove, and the adsorption part adsorbs the waste on the second cutting component. The waste discharge drive can also drive the waste discharge transmission component and link the waste discharge trolley to extend out of the avoidance groove and release the waste into the waste collection hopper.

[0046] Using the above technical solution, the adsorption unit on the waste discharge tray can reliably adsorb and fix the waste material remaining on the second cutting component after cutting. Combined with the sliding conveyor of the tray, it can accurately remove the waste material from the cutting station and send it into the waste collection hopper, preventing waste material from sticking, falling, or getting stuck in the cutting area. Furthermore, the waste discharge guide component guides the waste discharge tray, preventing it from shaking or tilting during the waste discharge process, and preventing waste material from falling off or scattering during transfer, further improving the reliability of waste discharge.

[0047] The present invention also discloses a cutting component of a bag making machine, wherein a heating component is provided on the side of the blade holder away from the blade.

[0048] A heating element is provided on the side of the cutting tool away from the tool holder.

[0049] By employing the above technical solution, and by installing heating components on the blade holder and / or blade, the high temperature during heat cutting of flexible packaging materials such as plastic film allows the cut edges to melt and solidify rapidly, effectively preventing problems such as stringing, burrs, loose threads, and delamination. This results in smooth and clean bag edges, improving the appearance and performance of the finished packaging bag. Furthermore, heating reduces the adhesion between waste material and the blade / blade holder, making it easier for waste material to be absorbed and detached from the cutting area. Combined with the waste material conveying component, this enables smoother waste removal and reduces the likelihood of jamming and clogging.

[0050] The present invention also discloses a cutting component of a bag making machine. The cutting tool includes multiple individual cutting tools that can be arbitrarily spliced ​​and combined to form cutting areas of different shapes.

[0051] By adopting the above technical solution, the enclosing size of a single cutting tool can be changed by adjusting the splicing position and the number of splices, thus achieving flexible adjustment of the cutting area size and enabling rapid adaptation to the cutting needs of different substrate specifications. Furthermore, if a single cutting tool is worn or damaged, it can be replaced individually without requiring overall replacement, reducing maintenance costs and extending the overall service life of the cutting components.

[0052] The present invention also discloses a bag making machine, including a frame and a cutting component of any of the above-mentioned bag making machines. The frame is further provided with a support plate for supporting the substrate to be cut. The support plate extends along a plane perpendicular to the punching direction. Furthermore, the support plate surrounds the cutting area where the cutter and the cutter holder of the cutting unit are connected and is flush with the cutting part in the punching direction.

[0053] By adopting the above technical solution, the cutting component of this bag-making machine has an adjustable projection area on the cutter holder due to the enclosed cutting area formed by the blades. This allows it to adapt to the cutting needs of different sizes and specifications of substrates without changing the blades and cutter holder, significantly reducing the machine's downtime for changeovers. Furthermore, the receiving plate extends in a plane perpendicular to the cutting direction, providing continuous and flat support to the substrate to be cut. This effectively prevents problems such as sagging, wrinkling, and shifting of flexible film substrates during transport, keeping the substrate taut and flat during cutting, significantly improving cutting dimensional accuracy and cut neatness.

[0054] The beneficial effects of this invention are as follows:

[0055] This invention discloses a cutting component for a bag-making machine, including a cutting unit. The cutting unit includes a cutting tool and a cutting tool holder, which are spaced apart on the frame of the bag-making machine along the cutting direction and are opposite to each other in the cutting direction. At least one of the cutting tool and the cutting tool holder can move towards each other along the cutting direction. The surface of the cutting tool facing the cutting tool holder is provided with a cutting edge facing the cutting tool holder. The cutting edge surrounds the cutting tool along the cutting direction to form a cutting area. The projected area of ​​the cutting area on the cutting tool holder is adjustable. This invention can adapt to the cutting needs of different sizes and specifications of substrates without changing the cutting tool and the cutting tool holder, significantly reducing the changeover downtime of the bag-making machine and improving the production efficiency and multi-specification applicability of the bag-making machine.

[0077] As mentioned in the background section, the cutting components of existing bag-making machines cannot meet the cutting requirements of different bag types, opening sizes, or specifications of packaging bags.

[0078] Therefore, the present invention provides a cutting component for a bag making machine, which can adjust the cutting area between the cutter and the cutter holder to meet the cutting requirements of substrates of different specifications and sizes.

[0079] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0080] like Figure 1 and Figure 2 As shown, this embodiment provides a cutting component for a bag making machine. This cutting component includes a cutting unit 10, which includes a cutter 101 and a cutter holder 102 that are spaced apart on the frame of the bag making machine along the cutting direction Z. The cutter 101 and the cutter holder 102 are arranged opposite to each other in the cutting direction Z. At least one of the cutter 101 and the cutter holder 102 can move toward each other along the cutting direction Z. The substrate cut by the cutting component can be plastic, paper, cloth, etc. In this embodiment, the substrate processed by the bag making machine is non-woven fabric as an example for explanation.

[0081] The surface of the cutting tool 101 facing the tool holder 102 is provided with a cutting edge 103 facing the tool holder 102 (see...). Figure 4 The cutting edge 103 forms a cutting area on the cutting tool 101 along the cutting direction Z, and the projected area of ​​the cutting area on the tool holder 102 is adjustable. It should be noted that the cutting edge 103 can be a strip-shaped sharp structure protruding towards the tool holder 102, which achieves cutting by shearing force, or it can be a strip-shaped pattern formed on the surface of the cutting tool 101 that is heated, which achieves cutting by high-temperature melting. This embodiment does not limit this to a single one. For ease of understanding, the example of the cutting edge 103 being a strip-shaped sharp structure protruding towards the tool holder 102 will be used for explanation.

[0082] It should be noted that the projected area of ​​the cutting area on the cutter holder 102 can be adjusted by changing the part where the cutting edge 103 on the cutter 101 meets the cutter holder 102. Only the part of the cutting edge 103 on the cutter 101 that meets the cutter holder 102 can perform the cutting function. For example, on a plane perpendicular to the punching direction Z, changing the position of the cutter 101, or changing the position of the cutter holder 102, or changing the positions of both the cutter 101 and the cutter holder 102, can change the part where the cutting edge 103 on the cutter 101 meets the cutter holder 102, thereby changing the projected area of ​​the cutting area on the cutter holder 102, which in turn changes the shape of the substrate cut by the cutting unit 10. Of course, the projected area of ​​the cutting area on the cutter holder 102 can also be adjusted by changing the cutting edge 103 along the punching direction Z to form the cutting area on the cutter 101. For example, changing the shape of the cutting edge 103 can achieve this, thereby changing the shape of the substrate cut by the cutting unit 10. This embodiment does not limit this only.

[0083] This cutting component allows at least one of the cutter 101 and the cutter holder 102 to move towards each other along the cutting direction Z, thereby cutting the substrate between the cutter 101 and the cutter holder 102. Furthermore, since the projected area of ​​the cutting area formed by the blades 103 on the cutter holder 102 is adjustable, it can adapt to the cutting needs of substrates of different sizes and specifications without changing the cutter 101 and the cutter holder 102, significantly reducing the changeover downtime of the bag-making machine and improving its production efficiency and multi-specification applicability.

[0084] Furthermore, the bag making machine does not require frequent replacement of the entire cutting unit 10, reducing the number of spare parts for the cutting tool 101, simplifying the debugging and disassembly process, and avoiding assembly errors caused by multiple disassembly and assembly, thus ensuring the accuracy of the cutting position and the stability of the cutting edge quality.

[0085] In addition, the size of the cutting area can be flexibly adjusted according to on-site conditions such as the width of the substrate and the design size of the bag, optimizing the cutting allowance, reducing raw material waste, improving the finished product qualification rate, and better meeting the needs of high-precision large-scale bag production.

[0086] The following is a detailed explanation of this adjustment method, which changes the part where the cutting edge 103 on the tool 101 mates with the tool holder 102.

[0087] Specifically, such as Figure 2 and Figure 3 As shown, in this embodiment, the cutting component further includes an adjustment unit 20, which is connected to the cutting unit 10 and moves relative to the planar linkage tool 101 and tool holder 102 perpendicular to the punching direction Z. Of course, the cutting unit 10 of the cutting component can also be manually adjusted, and this embodiment does not limit this to a single method.

[0088] In this embodiment, the adjustment unit 20 can accurately link the cutter 101 and the cutter holder 102 to move relative to each other in a plane perpendicular to the punching direction Z, thereby precisely and stably adjusting the projected area of ​​the cutting region on the cutter holder 102 to meet the cutting requirements of the bag making machine for different specifications of substrates. Compared with manual adjustment, this greatly improves the adjustment accuracy and efficiency of the cutting region. Specifically, the adjustment unit 20 can link the cutter 101 to move relative to the cutter holder 102 in a plane perpendicular to the punching direction Z, or link the cutter holder 102 to move relative to the cutter 101 in a plane perpendicular to the punching direction Z, or simultaneously link the cutter 101 and the cutter holder 102 to move relative to each other in a plane perpendicular to the punching direction Z. The movement method is not limited to moving along a certain direction in the plane perpendicular to the punching direction Z, or rotating around the axis of the punching direction Z, or moving along a certain direction in the plane perpendicular to the punching direction Z while rotating around the axis of the punching direction Z. The specific method can be selected according to the cutting region to be adjusted, and this embodiment does not impose a unique limitation on this.

[0089] In this embodiment, the cutting component includes a plurality of cutting units 10 spliced ​​together along the first direction X. The number of cutting units 10 can be two, three, or four, etc. Two adjacent cutting units 10 are connected together on the same side in the punching direction Z. For example, if the knife holder 102 and the knife 101 of two adjacent cutting units 10 are located on different sides in the punching direction Z, then the corresponding two components (knife holder 102 and knife 101) are connected together. For example, if the knife holder 102 and the knife 101 of two adjacent cutting units 10 are located on the same side in the punching direction Z, then the corresponding two components (knife holder 102 or knife 101) are connected together. The first direction X is perpendicular to the punching direction Z.

[0090] It should be noted that, in this embodiment, the cutting tool 101 and the tool holder 102 can be configured as opposing cuboid structures. The punching direction Z is the thickness direction of the cutting tool 101 and the tool holder 102. The first direction X can be the length direction of the cutting tool 101 and the tool holder 102, and the second direction Y is the width direction of the cutting tool 101 and the tool holder 102. The first direction X and the second direction Y are perpendicular to each other. The first direction X can also be the width direction of the cutting tool 101 and the tool holder 102, and the second direction Y can be the length direction of the cutting tool 101 and the tool holder 102. This embodiment does not limit this to a single direction.

[0091] Two adjacent components can be connected by snap-fit, screw-fit, or magnetic attraction. Of course, multiple components on the same side can also be formed together. This embodiment does not limit this to a single method.

[0092] Furthermore, the adjustment unit 20 is connected to at least a plurality of components of the plurality of cutting units 10 located on the same side in the punching direction Z, and moves in conjunction with the plurality of components located on the same side in the punching direction Z along a plane perpendicular to the punching direction Z.

[0093] This cutting component allows for more flexible setting of the cutting area through multiple sets of cutting units 10. The adjustment unit 20 can link multiple components of multiple cutting units 10 located on the same side to move synchronously, achieving overall unified adjustment of the projected area of ​​multiple cutting areas. Furthermore, the components on the same side of adjacent cutting units 10 are interconnected, resulting in stronger overall rigidity. During high-speed punching, it is less prone to vibration and displacement, effectively improving cutting stability and cut quality, and reducing defects such as burrs and misalignment.

[0094] Specifically, the adjustment unit 20 can be drivenly connected to multiple components located on the same side of the multiple cutting units 10 in the punching direction Z, and can move multiple components along the first direction X, or move multiple components along the second direction Y, thereby adjusting the cutting area. Of course, the adjustment unit 20 can also be drivenly connected to multiple components on both sides of the multiple cutting units 10 in the cutting direction, that is, it can move multiple components on both sides separately for adjustment. This embodiment does not limit this to a single method.

[0095] In one embodiment, among the plurality of cutting units 10, the tool holders 102 and the cutting tools 101 of the two outermost cutting units 10 located in the first direction X are located on different sides in the punching direction Z.

[0096] Furthermore, the adjustment unit 20 can move at least a number of components of the multiple cutting units 10 located on the same side of the punching direction Z along the first direction X, thereby adjusting the length of multiple cutting areas in the first direction X to meet the cutting requirements of different widths.

[0097] In this embodiment, the adjustment unit 20 and the multiple components located on both sides of the multiple cutting units 10 in the punching direction Z are connected by transmission and linkage, and the multiple components on both sides move towards or away from each other in the first direction X.

[0098] Compared to single-sided adjustment, the dual-sided adjustment of the adjustment unit 20, which simultaneously links multiple components on both sides of the cutting direction Z, offers advantages such as a wider adjustment range and higher adjustment efficiency. It can quickly adapt to the cutting needs of substrates of different specifications, from narrow to wide widths. Furthermore, the synchronous movement of the components on both sides, either facing or back to back, enables symmetrical adjustment of the projected area of ​​the cutting zone, ensuring that the center position of the cutting zone remains stable and preventing cutting center offset during adjustment. In addition, the adjustment unit 20 is simultaneously connected to multiple components on both sides via transmission, eliminating the need for dedicated adjustment structures for the components on both sides of the cutting direction Z, thus facilitating the arrangement of the cutting components on the frame of the bag-making machine.

[0099] More specifically, such as Figure 4 and Figure 5 As shown, taking a cutting component comprising two cutting units 10 as an example, the cutter 101 of one cutting unit 10 and the cutter holder 102 of the other cutting unit 10 are located on one side in the cutting direction Z and are joined together to form a first cutting component 110, and the cutter holder 102 of one cutting unit 10 and the cutter 101 of the other cutting unit 10 are located on the other side in the cutting direction Z and are joined together to form a second cutting component 120. It should be noted that in any cutting component, the cutting edge 103 on the cutter 101 and the receiving surface of the adjacent cutter holder 102 are flush in the cutting direction Z.

[0100] Furthermore, on the first cutting member 110 and the second cutting member 120, the cutting edges 103 of each cutter 101 extend along the first direction X, and both ends of the first cutting member X bend and extend along the second direction Y respectively. In the projection on the punching direction Z, the cutting edges 103 extending along the first direction X are aligned with each other, and the cutting edges 103 at both ends bend and extend towards the same side in the second direction Y. During the cutting process, the cutting edge 103 part of the first cutting member 110 extending along the first direction X may come into contact with the receiving surface of the cutter holder 102 on the second cutting member 120, or after the first cutting member 110 moves closer to the second cutting member 120 along the first direction X, the cutting edge 103 part of the first cutting member 110 extending along the first direction X will come into contact with the cutting edge 103 part of the second cutting member 120 extending along the first direction X. At this time, the cutting function can also be achieved.

[0101] This cutting component achieves the cutting of a predetermined area of ​​substrate by having the cutter 101 on the first cutting member 110 cooperate with the cutter holder 102 on the second cutting member 120, and the cutter holder 102 cooperate with the cutting edge 103 on the second cutting member 120. Furthermore, the cutting edges 103 on the second cutting member 120 and the second cutting member 120 extend along the first direction X and bend at both ends along the second direction Y. When the adjusting unit 20 moves the first cutting member 110 and the second cutting member 120 relative to each other along the first direction X, the cutting area enclosed by the first cutting member 110 and the second cutting member 120 can be changed.

[0102] Of course, the cutting edge 103 on each tool 101 is not limited to the structure in the above embodiment. The cutting edge 103 extending along the arc can also be designed according to the actual situation and specific needs. This embodiment does not limit this to a single one.

[0103] Furthermore, in this embodiment, the first cutting member 110 is movably disposed on the first guide member 410 extending along the first direction X on the frame via the first mounting member 310, and the second cutting member 120 is movably disposed on the second guide member 420 extending along the first direction X via the second mounting member 320.

[0104] Furthermore, the adjustment unit 20 has two transmission parts that are respectively connected to the first mounting component 310 and the second mounting component 320, and the first mounting component 310 and the second mounting component 320 move synchronously towards or away from each other in the first direction X.

[0105] Therefore, the cutting component provided in this embodiment guides and supports the first cutting member 110 and the second cutting member 120 through the first guide member 410 and the second guide member 420 respectively, making the translational movement of each cutting member in the first direction X more stable and smooth, avoiding deviation or jamming during the adjustment process, and ensuring adjustment accuracy. Furthermore, the adjustment unit 20 drives the first mounting member 310 and the second mounting member 320 through two transmission parts respectively, realizing synchronous movement of the first cutting member 110 and the second cutting member 120 towards or away from each other, which can precisely and symmetrically adjust the overall cutting width and the size of the cutting area.

[0106] Specifically, such as Figure 2 and Figure 3 As shown, the adjustment unit 20 includes an adjustment drive 210 and an intermediate transmission 220 disposed at the output end of the adjustment drive 210. The adjustment drive 210 is disposed on the frame. The intermediate transmission 220 is connected to the first mounting component 310 via a first transmission part 230 and to the second mounting component 320 via a second transmission part 240. The adjustment drive 210 drives the intermediate transmission 220 and moves the first mounting component 310 and the second mounting component 320 synchronously in the same or opposite directions in the first direction X.

[0107] In this embodiment, the adjustment unit 20 is provided with only one adjustment drive component, which has a simple and compact structure and is easy to arrange on the bag making machine. The adjustment drive component 210 drives the intermediate transmission component 220, and the first transmission part 230 and the second transmission part 240 respectively link the first mounting component 310 and the second mounting component 320, which can ensure that the first mounting component 310 and the second mounting component 320 move at the same height, avoiding problems such as inconsistent adjustment speed and position deviation, and significantly improving the size adjustment accuracy of the cutting area.

[0108] More specifically, the adjustment drive component 210 is configured as an adjustment drive motor 211, the intermediate transmission component 220 is configured as a transmission belt assembly 221, and a pair of transmission pulleys of the transmission belt assembly 221 are respectively sleeved on the ends of the first lead screw 231 constituting the first transmission part 230 and the second lead screw 241 constituting the second transmission part 240. The screws of the first lead screw 231 and the second lead screw 241 are screwed in opposite directions. The first lead screw 231 is connected to the first nut on the first mounting component 310, and the second lead screw 241 is connected to the second nut on the second mounting component 320.

[0109] Furthermore, both the first guide member 410 and the second guide member 420 are configured as adjusting guide rails extending along the first direction X, and the first mounting member 310 and the second mounting member 320 are slidably adapted to the corresponding adjusting guide rails.

[0110] In this embodiment, the drive motor 211, in conjunction with the transmission belt assembly 221, simultaneously drives the first lead screw 231 and the second lead screw 241, which rotate in opposite directions. Utilizing the transmission characteristics of the lead screw and nut pair, the first mounting component 310 and the second mounting component 320 automatically achieve synchronous translation towards or away from each other, thereby enabling accurate adjustment of the cutting area. Furthermore, the lead screw and nut pair possesses excellent self-locking characteristics, automatically locking the position of the cutting components after adjustment. This effectively resists vibration and impact during high-speed punching, preventing unexpected deviations in the cutting area size and ensuring cutting stability during long-term continuous production.

[0111] Of course, a gear set can also be set between the output end of the adjusting drive motor 211 and the first lead screw 231 and the second lead screw 241, with a driving gear fitted at the output end of the adjusting drive motor 211 and a driven gear fitted at the ends of the first lead screw 231 and the second lead screw 241, thereby achieving the purpose of the adjusting drive motor 211 driving the first lead screw 231 and the second lead screw 241 to move.

[0112] Of course, the adjustment unit 20 may also include a first adjustment component and a second adjustment component. The first adjustment component can drive the first mounting component 310 to move along the first direction X, and the second adjustment component can drive the second mounting component 320 to move along the first direction X, thereby realizing independent adjustment of the first cutting component 110 and the second cutting component 120. Specifically, the first adjustment component and the second adjustment component can be configured as a drive cylinder or a linear motor, etc., and their output ends are directly connected to the corresponding mounting components. This embodiment does not limit this to a single configuration.

[0113] The following is a detailed explanation of the adjustment method for changing the shape of the blade 103.

[0114] In this embodiment, the cutter 101 can be configured as a combination of multiple individual cutter units. The enclosing size of each individual cutter unit can be changed by adjusting the splicing position and the number of splices, thereby achieving flexible adjustment of the cutting area size and enabling quick adaptation to the cutting needs of different specifications of substrates. Furthermore, if a single cutter unit is worn or damaged, it can be replaced individually without replacing the entire unit, reducing maintenance costs and extending the overall service life of the cutting components.

[0115] It should be noted that the adjustment method of changing the part where the cutting edge 103 on the tool 101 mates with the tool holder 102 can be used in combination with the adjustment method of changing the shape of the cutting edge 103. This embodiment does not make specific limitations on this.

[0116] The following is a detailed description of the relevant structures of the cutting component used to drive the cutting process.

[0117] In this embodiment, as Figure 6As shown, a punching guide 311 extending along the punching direction Z is provided between the first mounting component 310 and the corresponding first cutting component 110. A punching drive component 50 is also provided on the first mounting component 310, and the punching drive component 50 drives the first cutting component 110 to move along the punching direction Z.

[0118] This cutting component, by providing a punching guide 311 extending along the punching direction Z between the first mounting component 310 and the first cutting member 110, ensures that the cutter 101 on the first cutting member 110 and the cutter holder 102 on the second cutting member 120 maintain precise alignment during the punching process, avoiding defects such as chipped edges, burrs, and incomplete cuts caused by off-center loading. Furthermore, during the cutting process, the second cutting member 120 on the second mounting component 320 does not require an additional drive structure, which contributes to the compactness of the cutting component.

[0119] Specifically, the die-cutting drive component 50 includes a die-cutting drive motor 510, a transmission disk 520, and a swing arm 530. The transmission disk 520 is located at the output end of the die-cutting drive motor 510. One end of the swing arm 530 is eccentrically connected to the transmission disk 520, and the other end is hinged to the side of the first cutting member 110 away from the second cutting member 120. Furthermore, the die-cutting guide 311 is configured as a die-cutting guide rail extending along the die-cutting direction Z. By driving the transmission disk 520 to rotate through the die-cutting drive motor 510, the rotational motion is converted into linear reciprocating motion of the first cutting member 110 along the die-cutting direction Z by the eccentrically connected swing arm 530. This transmission method provides smooth transmission and direct power transmission, enabling the first cutting member 110 to perform continuous and regular die-cutting actions. It is suitable for high-speed bag making operations and can maintain a stable die-cutting stroke and cutting force even at high speeds.

[0120] Of course, the punching drive component 50 can also be provided with a drive cylinder or linear motor that outputs power in a straight line. Furthermore, the punching drive component 50 can also be provided on the side of the second cutting component 120 away from the first cutting component 110, so that the first cutting component 110 and the second cutting component 120 move toward each other. This embodiment does not limit this to a single one.

[0121] In one embodiment, the punching direction Z is vertical, and the first cutting member 110 is located above the second cutting member 120 in the vertical direction.

[0122] And, as Figure 7 As shown, a waste collection component 60 is provided on the side of the second cutting component 120. A waste transfer component 70 is provided between the waste collection component 60 and the second cutting component 120. The waste transfer component 70 can transfer the waste on the second cutting component 120 into the waste collection component 60.

[0123] In this embodiment, the cutting component is equipped with a waste transfer component 70 and a waste collection component 60 on the side of the second cutting component 120. The cutting waste that falls on the second cutting component 120 after punching can be transferred to the waste collection component 60 in a timely manner, which can effectively prevent the waste from accumulating and getting stuck at the cutting position, prevent the waste from interfering with the base material conveying, bag forming and subsequent cutting operations, and ensure the continuous and smooth bag making process.

[0124] Furthermore, the punching direction Z is set to the vertical direction, and the first cutting member 110 is located above the second cutting member 120. The cut waste can fall naturally onto the second cutting member 120 below under the action of gravity. With the help of the waste transfer member 70, the waste can be transported more smoothly without the need for additional complex guide or lifting structures.

[0125] Specifically, the waste transfer component 70 includes a waste discharge drive component 710, a waste discharge transmission component 720, and a waste discharge tray 730. The waste discharge tray 730 is provided with an adsorption part and is slidably disposed on the waste discharge guide component 740. The first cutting component 110 is provided with a clearance groove 111 adapted to the waste discharge tray 730 on one side of the blade 103. The waste collection component 60 is a waste collection hopper 610.

[0126] The waste discharge drive component 710 can be a waste discharge drive motor or a waste discharge drive hydraulic cylinder, etc., which drives the waste discharge transmission component 720 (e.g., a connecting rod) and links the waste discharge slide 730 to extend into the clearance groove 111, and the adsorption part (e.g., multiple adsorption holes) adsorbs the waste on the second cutting component 120. The waste discharge drive component 710 can also drive the waste discharge transmission component 720 and link the waste discharge slide 730 to extend out of the clearance groove 111 and release the waste into the waste collection hopper 610.

[0127] In this embodiment, the adsorption section on the waste discharge tray 730 can reliably adsorb and fix the waste material remaining on the second cutting member 120 after cutting. Combined with the sliding transport of the tray, it can accurately remove the waste material from the cutting station and send it into the waste collection hopper 610, preventing the waste material from sticking, falling, or getting stuck in the cutting area. Furthermore, the waste discharge guide 740 guides the waste discharge tray 730, preventing shaking or tilting during the waste discharge process and preventing the waste material from falling off or scattering during transport, further improving the reliability of waste discharge.

[0128] Of course, the waste discharge tray 730 can also be replaced with a gripper, and the groove 111 can be avoided at the corresponding positions of the first cutting member 110 and the second cutting member 120. Then the gripper can pick up the waste from both sides of the waste and transfer it to the waste collection hopper 610. This embodiment does not limit this to a single method.

[0129] Furthermore, such as Figure 5As shown, a heating element 80 can be provided on the side of the blade holder 102 opposite to the blade 101. For example, the heating element 80 can be provided on the side of the second cutting member 120 opposite to the first cutting member 110. The heating element 80 can be an ultrasonic generator 810, an electric heating wire, or an electromagnetic heater commonly used in the art. When hot-cutting flexible packaging materials such as plastic film, the high temperature can quickly melt and solidify the cut edge, effectively avoiding problems such as stringing, rough edges, loose threads, and delamination at the cut, making the bag opening edge smooth and clean, and improving the appearance and performance of the finished packaging bag. In addition, heating can reduce the adhesion between waste material and the blade 103 and the blade holder 102, making it easier for waste material to be adsorbed and detached from the cutting area. Combined with the waste material transfer member 70, it can achieve smoother waste discharge and reduce the probability of material jamming and clogging.

[0130] Of course, the heating element 80 can also be provided on the side of the tool 101 away from the tool holder 102, or the heating element 80 can be provided on both the side of the tool holder 102 away from the tool 101 and the side of the tool 101 away from the tool holder 102. This embodiment does not limit this to a single one.

[0131] This embodiment also discloses a bag-making machine, such as Figure 1 As shown, the bag making machine includes a frame and a cutting component of any of the above-mentioned types. The frame is also provided with a support plate 90 for supporting the substrate to be cut. The support plate 90 extends along a plane perpendicular to the punching direction Z. Furthermore, the support plate 90 surrounds the cutting area where the cutter 101 and the cutter holder 102 of the cutting unit 10 are connected to each other, and is flush with the cutting part in the punching direction Z.

[0132] In this embodiment, the cutting component of this bag-making machine has an adjustable projection area on the cutter holder 102 due to the cutting area formed by the blades 103. This allows it to adapt to the cutting needs of different sizes and specifications of substrates without changing the blades 101 and the cutter holder 102, significantly reducing the machine's downtime for changeovers. Furthermore, the receiving plate 90 extends in a plane perpendicular to the punching direction Z, providing continuous and flat support to the substrate to be cut. This effectively prevents problems such as sagging, wrinkling, and shifting of flexible film substrates during transport, keeping the substrate taut and flat during cutting, and significantly improving the cutting dimensional accuracy and cut neatness.

[0133] Furthermore, such as Figure 1 As shown, the receiving plate 90 may have a pressure plate 910 spaced apart on the side of the punching direction Z toward the first cutting member 110, and the substrate is located between the receiving plate 90 and the pressure plate 910 to improve the stability of the substrate during cutting.
