Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag processing, in particular to a substrate cutting device used for bag body forming equipment. Background Art

[0002] Packaging bags are a type of container widely used in commodity packaging. They play an important role in protecting products, facilitating carrying, promoting sales and enhancing brand image.

[0003] Traditional packaging bag substrates are generally in the shape of a whole rectangle formed by a cutting knife when they are sent to the forming component. The substrate is then pressed into the forming component by a pressing component to form the packaging bag. However, as user needs and the shape of the packaging bag change, the substrate may need to be cut or punched.

[0004] In the prior art, the punching structure is fixed on the frame, and when the substrate is conveyed to the cutting and punching mechanism, the substrate is cut or punched. However, during the molding process, since the substrate needs to go through multiple steps, each step more or less exerts a force on the substrate on the conveyor belt, causing the continuous substrate to shake frequently when moving on the conveyor belt, which greatly affects the accuracy of the punching mechanism when punching or cutting the substrate, resulting in some of the cut substrate failing to meet the molding requirements, reducing the yield of the packaging bag, and also causing some of the substrate to be wasted. Utility Model Content

[0005] The purpose of the utility model is to solve the technical problem in the prior art that a continuous substrate frequently shakes when moving on a conveyor belt, which greatly affects the accuracy of the punching mechanism when punching or cutting the substrate, resulting in part of the cut substrate failing to meet the molding requirements, reducing the yield of the packaging bag and also causing part of the substrate to be wasted.

[0006] In order to solve the above technical problems, the embodiment of the utility model discloses a substrate cutting device for bag forming equipment, and the substrate cutting device is arranged outside one side edge of the substrate in the transport direction.

[0007] This substrate cutting device includes a cutting component, a driving component and a substrate stabilizing component, wherein the cutting component includes a cutter and a cutter holder arranged relatively on both sides of the substrate in a direction perpendicular to the surface of the substrate, and the cutter and the cutter holder overlap with at least a portion of the edge area of ​​the substrate in a projection perpendicular to the direction along the surface of the substrate; the cutter is transmission-connected to the driving component, and the driving component drives the cutter to move in a direction perpendicular to the surface of the substrate and in a direction close to or away from the cutter holder.

[0008] Moreover, the substrate stabilizing member is located on the upstream side of the cutting member in the transport direction and has a material stabilizing channel that extends through the substrate stabilizing member in the transport direction. In the transport direction, the material stabilizing channel is aligned with the cutting channel between the tool holder and the cutting tool, and at least a part of the substrate is located in the material stabilizing channel during cutting.

[0009] With the above technical solution, this substrate cutting device is arranged outside one edge of the substrate in the transport direction. When the substrate is transported in the transport direction, since the cutting tool and the tool holder at least coincide with a part of the edge area of the substrate, the driving member drives the cutting tool to move towards the tool holder in a direction perpendicular to the surface of the substrate, and will cut a part of the substrate between the cutting tool and the tool holder. Moreover, in the transport direction, a substrate stabilizing member is arranged on the upstream side of the cutting member. Before the substrate is cut, the substrate will first pass through the material stabilizing channel of the substrate stabilizing member, thereby restricting the jitter of the substrate, enabling the substrate to pass through the cutting channel between the cutting tool and the tool holder more stably, and thus being cut by the cutting tool, improving the cutting accuracy of the cutting member for the substrate, ensuring that the substrate can be cut into the expected shape, meeting the subsequent production requirements, and improving the yield rate of the packaging bag.

[0010] In addition, in the transport direction, the material stabilizing channel is aligned with the cutting channel between the tool holder and the cutting tool, which can ensure that the substrate before entering the cutting channel will necessarily pass through the material stabilizing channel first to achieve a better material stabilizing effect.

[0011] An embodiment of the present invention also discloses a substrate cutting device for a bag body forming device. In the transport direction, the material stabilizing channel includes an inlet section, a middle section, and an outlet section that are interconnected.

[0012] Wherein, in a cross-section taken along the transport direction, the channel depth of the inlet section in the direction perpendicular to the substrate is greater than the channel depth of the middle section, and the channel depth of the outlet section is equal to or greater than the channel depth of the middle section. Moreover, the inner walls of the inlet section, the middle section, and the outlet section are smoothly connected in sequence.

[0013] With the above technical solution, when the substrate passes through the material stabilizing channel, it first passes through the inlet section of the material stabilizing channel. The channel depth of the inlet section in the direction perpendicular to the substrate is greater than the channel depth of the middle section, which is convenient for the substrate to extend into the material stabilizing channel, while the channel depth of the outlet section is equal to or greater than the channel depth of the middle section, which is beneficial for the substrate to extend out of the material stabilizing channel. Therefore, this structure of the material stabilizing channel can improve the passability of the substrate.

[0014] In addition, the inner walls of the inlet section, the middle section, and the outlet section are smoothly connected in sequence, ensuring that the substrate can move smoothly in the material stabilizing channel along the transport direction.

[0015] An embodiment of the present utility model also discloses a base material cutting device for a bag body forming device. The base material stabilizing component includes a first stabilizing plate and a second stabilizing plate that are spaced apart from each other in a direction perpendicular to the base material. The gap cavity between the first stabilizing plate and the second stabilizing plate forms a stabilizing channel. The surface of the first stabilizing plate is flush with the upper surface of the tool holder. The second stabilizing plate is closer to the tool than the first stabilizing plate and extends at least partially parallel to the transportation direction.

[0016] With the above technical solution, the first stabilizing plate and the second stabilizing plate that are spaced apart from each other in a direction perpendicular to the base material can limit the shaking of the base material in a direction perpendicular to the surface of the base material. Moreover, the surface of the first stabilizing plate is flush with the upper surface of the tool holder, ensuring that the base material output from the first stabilizing plate and the second stabilizing plate can be output to the upper surface of the tool holder, thus facilitating cutting.

[0017] An embodiment of the present utility model also discloses a base material cutting device for a bag body forming device. The upstream portion of the second stabilizing plate in the transportation direction extends obliquely in a direction close to the first stabilizing plate, and an inlet section of the stabilizing channel is formed between the upstream portions of the first stabilizing plate and the second stabilizing plate.

[0018] The middle portion of the second stabilizing plate in the transportation direction extends parallel to the transportation direction, and a middle section of the stabilizing channel is formed between the middle portions of the first stabilizing plate and the second stabilizing plate.

[0019] The downstream portion of the second stabilizing plate in the transportation direction extends curvedly in a direction away from the first stabilizing plate, and an outlet section of the stabilizing channel is formed between the downstream portions of the first stabilizing plate and the second stabilizing plate.

[0020] With the above technical solution, when the base material enters between the first stabilizing plate and the second stabilizing plate, the lower surface of the base material adheres to the first stabilizing plate. The upstream portion of the second stabilizing plate in the transportation direction extends obliquely in a direction close to the first stabilizing plate, which can smooth out the wrinkles on the base material and play a guiding role. The middle portion of the second stabilizing plate in the transportation direction extends parallel to the transportation direction, that is, parallel to the upper surface of the base material, thereby restricting the shaking of the base material in a direction perpendicular to the surface of the base material. The downstream portion of the second stabilizing plate in the transportation direction extends curvedly in a direction away from the first stabilizing plate, which is beneficial for the base material to extend out from the downstream side.

[0021] An embodiment of the present utility model also discloses a base material cutting device for a bag body forming device. The first stabilizing plate and the second stabilizing plate are connected to each other through a connecting portion beside the stabilizing channel.

[0022] Moreover, the first stabilizing plate is fixedly connected to the upstream side edge of the tool holder in the transportation direction.

[0023] With the above technical solution, the connecting part arranged beside the material stabilizing channel can ensure the stability of the material stabilizing channel formed between the first material stabilizing plate and the second material stabilizing plate on the premise of ensuring the firm connection between the first material stabilizing plate and the second material stabilizing plate.

[0024] In addition, the first material stabilizing plate is connected to the upstream side edge of the tool holder in the transportation direction, avoiding the relative movement of the first material stabilizing plate and the second material stabilizing plate with respect to the tool holder, and ensuring that in the transportation direction, the material stabilizing channel is aligned with the cutting channel between the tool holder and the cutting tool to achieve a better material stabilizing effect.

[0025] An embodiment of the present utility model also discloses a base material cutting device for a bag body forming device. The base material cutting device further includes a mounting frame mounted on the tool holder, and a driving component and a transmission component are arranged on the mounting frame, and the cutting tool is connected to the output end of the driving component through the transmission component.

[0026] Among them, the transmission component includes a guiding member arranged on the side of the cutting tool facing away from the tool holder and extending in a direction perpendicular to the surface of the base material. The guiding member is adapted to a guiding groove extending in a direction perpendicular to the surface of the base material on the mounting frame.

[0027] And the transmission component further includes an intermediate transmission unit. The input end of the intermediate transmission unit is in transmission connection with the output end of the driving component, and the output end is in transmission connection with the guiding member, and the cutting tool is driven to move in a direction perpendicular to the surface of the base material through the guiding member.

[0028] With the above technical solution, the driving component drives the cutting tool to move through the intermediate transmission unit to transmit power to the guiding member, and the guiding member assembled in the guiding groove can ensure that the cutting tool moves in a direction perpendicular to the surface of the base material, so as to cut the base material. This structure can utilize the cooperation between the guiding member and the guiding groove to limit the moving direction of the cutting tool, so that the cutting direction of the cutting tool on the base material is always perpendicular to the direction of the surface of the base material, thereby improving the cutting accuracy.

[0029] An embodiment of the present utility model also discloses a base material cutting device for a bag body forming device, and the driving component is set as a rotary motor.

[0030] Among them, the intermediate transmission unit includes a reducer and an intermediate transmission member. The reducer is connected to the rotary motor by belt transmission, and an eccentric wheel shaft is provided on the output shaft of the reducer. A connecting member is connected to the end of the eccentric wheel shaft, the connecting member is connected to the intermediate transmission member, and the intermediate transmission member is fixedly connected to the guiding member.

[0031] The eccentric wheel shaft rotates and drives the intermediate transmission member and the guiding member to move in a direction perpendicular to the surface of the base material through the connecting member.

[0032] With the above technical solution, the power of the rotary motor is output to the speed reducer. The eccentric wheel shaft on the speed reducer rotates, and through the connecting member, the intermediate transmission member and the guiding member are linked to move in a direction perpendicular to the surface of the base material. The speed reducer plays a role in reducing speed and increasing torque, ensuring that the force transmitted to the tool is sufficient for the tool to cut the base material. By cooperating the connecting member with the intermediate transmission member, the rotation of the eccentric wheel shaft is converted into the movement of the guiding member in a direction perpendicular to the surface of the base material, and the guiding member links the tool to perform cutting.

[0033] An embodiment of the present utility model also discloses a base material cutting device for a bag body forming device. The connecting member is arranged in a plate-like structure, and one side wall surface of the connecting member is connected to the eccentric wheel shaft, and a limiting groove extending in a direction parallel to the surface of the base material is formed on the other side wall surface. A limiting guide rail adapted to the limiting groove is formed on the corresponding side wall of the intermediate transmission member.

[0034] With the above technical solution, the limiting groove on the connecting member cooperates with the limiting guide rail on the intermediate transmission member. On the one hand, when the eccentric wheel shaft rotates, the connecting member can move relative to the intermediate transmission member in a direction parallel to the surface of the base material, and the intermediate transmission member, under the linkage of the connecting member, moves along the extending direction of the guiding groove, that is, in a direction perpendicular to the surface of the base material, so as to drive the tool to perform cutting; on the other hand, it also plays a role in limiting the connecting member, avoiding the shaking of the connecting member arranged on the eccentric wheel shaft.

[0035] This structure cleverly utilizes the cooperation of two sets of sliding members (the guiding member and the guiding groove, the limiting groove and the limiting guide rail) to realize the conversion of the rotation of the eccentric wheel shaft into the translation of the tool in a direction perpendicular to the surface of the base material. Compared with using a linkage rod to transmit the power of the eccentric wheel shaft to the tool, the transmission method using sliding members has less wear and is more reliable, thereby prolonging the service life of the transmission components.

[0036] An embodiment of the present utility model also discloses a base material cutting device for a bag body forming device. The surface of the tool facing the tool holder is a plane, and a cutting groove adapted to the edge of the tool is formed on the surface of the tool holder facing the tool.

[0037] Furthermore, the base material cutting device further includes a tool guiding portion spaced from the tool holder in a direction perpendicular to the surface of the base material. A tool guiding groove adapted to the tool is formed on the tool guiding portion, and the tool is slidably arranged in the tool guiding groove in a direction perpendicular to the surface of the base material.

[0038] Wherein, one end of the tool guiding portion is connected to the corresponding end of the tool holder, and a cutting channel is formed between the opposite end faces of the tool holder and the tool guiding portion.

[0039] With the above technical solution, a cutting groove matching the edge of the cutter is formed on the surface of the cutter seat facing the cutter, and when the cutter moves toward the cutter seat to cut the substrate, it can be embedded in the cutting groove, thereby ensuring that the portion to be cut is separated from the substrate as a whole. In addition, the cutter guide groove on the cutter guide part can further guide the moving direction of the cutter and improve the cutting accuracy of the cutter.

[0040] The embodiment of the utility model also discloses a substrate cutting device for bag forming equipment, which also includes a follower component, which is transmission-connected to a knife holder and links the knife holder to move along the transport direction.

[0041] The follower assembly includes a follower motor, a transmission screw and a follower guide rail along the transport direction, and the follower motor and the transmission screw are connected through a belt drive.

[0042] In addition, a connecting block matched with the follower screw rod and a sliding block slidably connected with the follower guide rail are arranged at the bottom of the knife seat.

[0043] With the above technical solution, due to the requirements of bag forming, the intervals between two adjacent cutting parts on the substrate are different. Through the follower assembly, the knife seat can be linked to move along the transport direction to adjust the position of the substrate cutting device in the transport direction. In addition, since the screw drive has the advantage of high transmission accuracy, the power transmitted by the follower motor is output to the knife seat through the transmission screw, which can more accurately control the movement of the knife seat, and the follower guide rail extending along the transport direction can guide the movement of the knife seat through the slider on the knife seat.

[0044] The embodiment of the utility model also discloses a substrate cutting device for bag forming equipment, which also includes a waste collecting member, which is located on the side of the substrate away from the cutting member in a direction perpendicular to the surface of the substrate; wherein

[0045] In a direction perpendicular to the surface of the substrate, the waste collecting member is in a funnel-shaped structure which is recessed in a direction away from the cutting member, and a waste discharge port is formed at the bottom of the waste collecting member.

[0046] By adopting the above technical solution, the waste collection piece arranged on the side of the substrate away from the cutting component can, on the one hand, collect the cut waste for easy cleaning; on the other hand, prevent the waste from falling onto other parts of the bag forming equipment and affecting the normal operation of other parts.

[0047] Furthermore, the waste collecting member is a funnel-shaped structure that is recessed in a direction away from the cutting member, and can guide the waste falling into the waste collecting member to fall toward the waste discharge port at the bottom, thereby avoiding waste accumulation.

[0048] The beneficial effects of the utility model are:

[0049] The utility model discloses a base material cutting device for a bag body forming device, which comprises a cutting component, a driving component and a base material stabilizing component. Among them, the cutting component includes a cutter and a tool holder which are oppositely arranged on both sides of the base material in a direction perpendicular to the surface of the base material, and, within the projection in the direction perpendicular to the surface of the base material, the cutter and the tool holder at least coincide with a partial edge area of the base material; the cutter is in transmission connection with the driving component, and the driving component drives the cutter to move in a direction perpendicular to the surface of the base material and towards or away from the tool holder. The base material stabilizing component is located on the upstream side of the cutting component in the transportation direction and has a material stabilizing channel that extends through the base material stabilizing component in the transportation direction. In the transportation direction, the material stabilizing channel is aligned with the cutting channel between the tool holder and the cutter. When being cut, the base material is at least partially located in the material stabilizing channel. The base material will first pass through the material stabilizing channel of the base material stabilizing component, thereby restricting the jitter of the base material, enabling the base material to pass through the cutting channel between the cutter and the tool holder more stably, and thus being cut by the cutter, improving the cutting accuracy of the cutting component for the base material.

[0082] Packaging bags are flexible containers used to hold, protect and transport goods, usually made of plastic, paper, cloth and other materials. With the increasing awareness of environmental protection, non-woven bags, as an environmentally friendly product, have a growing market demand. Non-woven bags are made of non-woven fabrics. Non-woven fabrics are a new type of fiber product with the characteristics of moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating. The material can be naturally decomposed in 90 days outdoors and has a service life of up to 5 years indoors. It is non-toxic, odorless, and has no residual substances when burned, and does not pollute the environment.

[0083] During the production process of packaging bags, the entire substrate needs to be processed so that the shape of the substrate meets the molding requirements. Specifically, when the transport component transports the substrate to the molding component, a cutting and punching mechanism is provided upstream of the molding component. When the substrate is transported to the cutting and punching mechanism, the substrate is cut or punched. However, during the entire molding process, since the substrate needs to go through multiple processes (such as creases, ironing, folding, etc.), each process more or less exerts a force on the substrate on the conveyor belt, resulting in frequent shaking of the continuous substrate when moving on the conveyor belt, which greatly affects the accuracy of the punching mechanism when punching or cutting the substrate, resulting in part of the cut substrate failing to meet the molding requirements, reducing the yield of the packaging bag, and also causing part of the substrate to be wasted.

[0084] To this end, the utility model provides a substrate cutting device for bag forming equipment, the substrate cutting device for bag forming equipment includes a cutting component, a driving component and a substrate stabilizing component, the cutting component includes a cutter and a cutter holder arranged relative to each other in a direction perpendicular to the surface of the substrate, the cutter and the cutter holder at least overlap with a portion of the edge area of ​​the substrate, the cutter is connected to the driving component in a transmission manner, and the driving component drives the cutter to move in a direction perpendicular to the surface of the substrate to cut the substrate. The substrate stabilizing component is located on the upstream side of the cutting component in the transport direction, and has a material stabilizing channel extending through the substrate stabilizing component in the transport direction. The substrate will first pass through the material stabilizing channel of the substrate stabilizing component, thereby limiting the shaking of the substrate, so that the substrate can pass through the cutting channel between the cutter and the cutter holder more stably, thereby improving the cutting accuracy of the substrate by the cutting component.

[0085] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0086] like Figure 1 and Figure 9 As shown, the embodiment of the utility model provides a substrate cutting device 10 for a bag forming device, and the substrate cutting device 10 is arranged outside the edge of one side of the substrate in the transport direction Y. It should be noted that the substrate processed by the bag forming device can be plastic, paper, cloth, etc. In this embodiment, the substrate processed by the bag forming device is a non-woven fabric. Of course, regarding the specific selection of the substrate, those skilled in the art can design it according to the actual situation and specific needs, and this embodiment does not make specific limitations on this.

[0087] Specifically, Figure 1 As shown, the substrate cutting device 10 includes a cutting component 100, a driving component 200 and a substrate stabilizing component 400, wherein the cutting component 100 includes a tool 110 and a tool holder 120 which are relatively arranged on both sides of the substrate in a direction perpendicular to the surface of the substrate, and, in a projection perpendicular to the direction along the surface of the substrate, the tool 110 and the tool holder 120 at least overlap with a portion of the edge area of ​​the substrate; the tool 110 is transmission-connected to the driving component 200, and the driving component 200 drives the tool 110 to move in a direction Z perpendicular to the surface of the substrate, toward or away from the tool holder 120.

[0088] And, if Figure 2 As shown, the substrate stabilizing component 400 is located on the upstream side of the cutting component 100 in the transport direction Y, and has a material stabilizing channel 401 extending through the substrate stabilizing component 400 along the transport direction Y. In the transport direction Y, the material stabilizing channel 401 is aligned with the cutting channel 101 between the knife seat 120 and the knife 110, and the substrate is at least partially located in the material stabilizing channel 401 during cutting.

[0089] This substrate cutting device 10 is arranged outside one side edge of the substrate in the transportation direction Y. When the substrate is transported along the transportation direction Y, since the cutter 110 and the tool holder 120 at least coincide with part of the edge area of the substrate, the driving component 200 drives the cutter 110 to move towards the tool holder 120 in the direction Z perpendicular to the surface of the substrate, and will cut part of the substrate between the cutter 110 and the tool holder 120. Moreover, in the transportation direction Y, a substrate stabilizing component 400 is arranged on the upstream side of the cutting component 100. Before the substrate is cut, the substrate will first pass through the material stabilizing channel 401 of the substrate stabilizing component 400, thereby restricting the jitter of the substrate, enabling the substrate to pass through the cutting channel 101 between the cutter 110 and the tool holder 120 more stably, and thus being cut by the cutter 110, improving the cutting accuracy of the cutting component 100 for the substrate, ensuring that the substrate can be cut into the expected shape, meeting the subsequent production requirements, and improving the yield rate of the packaging bag.

[0090] In addition, in the transportation direction Y, the material stabilizing channel 401 is aligned with the cutting channel 101 between the tool holder 120 and the cutter 110, which can ensure that the substrate before entering the cutting channel 101 will necessarily pass through the material stabilizing channel 401 first to achieve a better material stabilizing effect.

[0091] As described above, the cutting component 100 is a component for cutting the substrate. The driving component 200 drives the cutter 110 to move in the direction Z perpendicular to the surface of the substrate, towards or away from the tool holder 120, thereby cutting the substrate. The cutter 110 cuts the substrate in the direction Z perpendicular to the surface of the substrate, that is, cuts the substrate directly facing it, with a better cutting effect, and can reduce the burrs on the cut edge of the substrate. Of course, those skilled in the art can design according to the actual situation and specific requirements. For example, in the case of limited space, the cutter 110 is made to move obliquely towards the substrate relative to the direction Z perpendicular to the surface of the substrate. The present utility model does not make specific limitations on this.

[0092] Furthermore, regarding the driving component 200 for driving the cutter 110 to move, it can be set as a commonly used rotary motor in the art, and through multiple groups of sliding components, it cooperates to realize the linkage of the cutter 110 in the direction Z perpendicular to the surface of the substrate. Of course, a cylinder or a linear motor with linear input power can be set to drive the cutter 110 to move in the direction Z perpendicular to the surface of the substrate. This embodiment does not make a unique limitation on this.

[0093] In addition, regarding the shape of the cutter 110, it can be designed according to the cutting requirements on the substrate. For example, in this embodiment, the shape of the cutter 110 is rectangular, which can cut regular rectangular notches at the edge of the substrate. Of course, rectangular holes can also be cut inside the substrate according to the requirements. The shape of the cutter 110 can also be set as circular, elliptical or triangular. This embodiment does not make specific limitations on this.

[0094] The substrate stabilizing member 400 provided on the upstream side of the cutting member 100 is to weaken the tendency of the substrate to vibrate in the direction Z perpendicular to the surface of the substrate, so that the substrate can enter the cutting channel 101 more smoothly and thus be cut by the cutting tool 110. The substrate stabilizing member 400 can be provided with stabilizing plates disposed at intervals on both sides of the substrate perpendicular to the substrate. The substrate is restricted by the stabilizing plates on both sides, reducing the amplitude and frequency of vibration of the substrate before entering the cutting channel 101. Of course, the substrate stabilizing member 400 can also be provided as transport rollers disposed at intervals on both sides of the substrate in the direction Z perpendicular to the surface of the substrate. Those skilled in the art can design according to the actual situation and specific requirements, and this embodiment does not make specific limitations in this regard.

[0095] The structure of the substrate stabilizing member 400 will be described in detail below.

[0096] As Figure 2 shown, in the transport direction Y, the stabilizing channel 401 includes an inlet section 402, an intermediate section 403, and an outlet section 404 that are interconnected.

[0097] Among them, in the cross-section taken along the transport direction Y, the channel depth of the inlet section 402 in the direction perpendicular to the substrate is greater than the channel depth of the intermediate section 403, and the channel depth of the outlet section 404 is greater than the channel depth of the intermediate section 403. Moreover, the inner walls of the inlet section 402, the intermediate section 403, and the outlet section 404 are smoothly connected in sequence. Of course, in another embodiment, the channel depth of the outlet section 404 can also be equal to the channel depth of the intermediate section 403.

[0098] It should be noted that in this embodiment, the channel height of the intermediate section 403 is adapted to the thickness of the substrate. Of course, the channel height of the intermediate section 403 can also be slightly greater than the thickness of the substrate. Those skilled in the art can design according to the actual situation and specific requirements, and this embodiment does not make specific limitations in this regard.

[0099] When the substrate passes through the stabilizing channel 401, it first passes through the inlet section 402 of the stabilizing channel 401. The channel depth of the inlet section 402 in the direction perpendicular to the substrate is greater than the channel depth of the intermediate section 403, which is convenient for extending the substrate into the stabilizing channel 401. And the channel depth of the outlet section 404 is equal to or greater than the channel depth of the intermediate section 403, which is beneficial for the substrate to extend out of the stabilizing channel 401. Therefore, the stabilizing channel 401 with this structure can improve the passing performance of the substrate.

[0100] In addition, the inner walls of the inlet section 402, the intermediate section 403, and the outlet section 404 are smoothly connected in sequence, ensuring that the substrate can move smoothly in the stabilizing channel 401 along the transport direction Y.

[0101] Specifically, asFigure 2 and Figure 3 As shown in Figure 3 , the substrate stabilizing member 400 includes a first material stabilizing plate 410 and a second material stabilizing plate 420 that are spaced apart from each other in a direction perpendicular to the substrate. The gap cavity between the first material stabilizing plate 410 and the second material stabilizing plate 420 forms a material stabilizing channel 401. The surface of the first material stabilizing plate 410 is flush with the upper surface of the tool holder 120. The second material stabilizing plate 420 is closer to the tool 110 than the first material stabilizing plate 410 and extends at least partially parallel to the transport direction Y.

[0102] In this embodiment, the first material stabilizing plate 410 and the second material stabilizing plate 420 that are spaced apart from each other in a direction perpendicular to the substrate can limit the shaking of the substrate in the direction Z perpendicular to the surface of the substrate. Moreover, the surface of the first material stabilizing plate 410 is flush with the upper surface of the tool holder 120, ensuring that the substrate output from the first material stabilizing plate 410 and the second material stabilizing plate 420 can be output to the upper surface of the tool holder 120, facilitating cutting.

[0103] Furthermore, in this embodiment, the upstream portion of the second material stabilizing plate 420 in the transport direction Y extends obliquely in a direction close to the first material stabilizing plate 410, and an inlet section 402 of the material stabilizing channel 401 is formed between the upstream portions of the first material stabilizing plate 410 and the second material stabilizing plate 420.

[0104] The middle portion of the second material stabilizing plate 420 in the transport direction Y extends parallel to the transport direction Y, and a middle section 403 of the material stabilizing channel 401 is formed between the middle portions of the first material stabilizing plate 410 and the second material stabilizing plate 420.

[0105] The upstream and downstream portions of the second material stabilizing plate 420 in the transport direction Y extend in a direction away from the first material stabilizing plate 410 in a curved manner, and an outlet section 404 of the material stabilizing channel 401 is formed between the downstream portions of the first material stabilizing plate 410 and the second material stabilizing plate 420.

[0106] When the substrate enters between the first material stabilizing plate 410 and the second material stabilizing plate 420, the lower surface of the substrate fits on the first material stabilizing plate 410. The upstream portion of the second material stabilizing plate 420 in the transport direction Y extends obliquely in a direction close to the first material stabilizing plate 410, which can smooth the wrinkles on the substrate, play a guiding role, and can prevent the substrate from being scratched by the edge of the second material stabilizing plate 420 when the substrate shakes. The middle portion of the second material stabilizing plate 420 in the transport direction Y extends parallel to the transport direction Y, that is, parallel to the upper surface of the substrate, thus restricting the shaking of the substrate in the direction perpendicular to the surface of the substrate. The downstream portion of the second material stabilizing plate 420 in the transport direction Y extends in a direction away from the first material stabilizing plate 410 in a curved manner, which is beneficial for the substrate to extend out from the downstream side.

[0107] As Figure 2 and Figure 3As shown, in this embodiment, the first material stabilizing plate 410 and the second material stabilizing plate 420 are connected to each other through a connecting portion 440 beside the material stabilizing channel 401. It should be noted that the connecting portion 440 can be set as connecting holes at corresponding positions on the first material stabilizing plate 410 and the second material stabilizing plate 420. By passing fastening bolts through the connecting holes at corresponding positions on the first material stabilizing plate 410 and the second material stabilizing plate 420, the first material stabilizing plate 410 and the second material stabilizing plate 420 are connected together.

[0108] Specifically, on the side of the material stabilizing channel 401, the first material stabilizing plate 410 and the second material stabilizing plate 420 are provided with two pairs of connecting holes at intervals along the transportation direction Y. Of course, three pairs, four pairs or other numbers of connecting holes can be set, and this embodiment does not make a unique limitation on this.

[0109] In another embodiment, the connecting portion 440 is set as: a protruding structure at the side position of the first material stabilizing plate 410 beside the material stabilizing channel 401, and a concave structure adapted to the protruding structure is formed at the corresponding position on the second material stabilizing plate 420, and the first material stabilizing plate 410 and the second material stabilizing plate 420 are clamped to each other.

[0110] And, as Figure 2 and Figure 3 shown, the first material stabilizing plate 410 is fixedly connected to the upstream side edge of the tool holder 120 in the transportation direction Y. Specifically, a connecting plate 411 extending in the direction Z perpendicular to the surface of the substrate is formed on one side edge of the first material stabilizing plate 410 close to the tool holder 120. The first material stabilizing plate 410 is fixedly connected to the tool holder 120 through the connecting plate 411. Regarding the structural connection method, it can be screwed or clamped, and this embodiment does not make a specific limitation on this.

[0111] More specifically, two round holes are provided on the connecting plate 411, and a strip hole corresponding to the round holes on the connecting plate 411 and extending in the direction Z perpendicular to the surface of the substrate is formed on the upstream side edge of the tool holder 120. And by passing fastening bolts through the round holes on the connecting plate 411 and the corresponding strip holes on the tool holder 120, the first material stabilizing plate 410 and the tool holder 120 are fixedly connected. And through the strip hole, the installation position of the first material stabilizing plate 410 can be adjusted in the direction Z perpendicular to the surface of the substrate.

[0112] In this embodiment, the connecting portion 440 provided beside the material stabilizing channel 401 can ensure the stability of the material stabilizing channel 401 formed between the first material stabilizing plate 410 and the second material stabilizing plate 420 on the premise of a firm connection between the first material stabilizing plate 410 and the second material stabilizing plate 420.

[0113] In addition, the first material stabilizing plate 410 is connected to the upstream side edge of the tool holder 120 in the transport direction Y, preventing the first material stabilizing plate 410 and the second material stabilizing plate 420 from moving relative to the tool holder 120, ensuring that in the transport direction Y, the material stabilizing channel 401 is aligned with the cutting channel 101 between the tool holder 120 and the cutting tool 110 to achieve a better material stabilizing effect.

[0114] In another embodiment, the substrate stabilizing member 400 is configured such that: along the direction Z perpendicular to the surface of the substrate, relative to the transport rollers on both sides of the substrate, the distance between the two transport rollers is adapted to the thickness of the substrate. When the substrate passes between the two transport rollers, the two transport rollers squeeze the substrate, reducing the amplitude and frequency of the substrate jitter. Of course, the specific structure of the substrate stabilizing member 400 is not limited to the above two structures, and those skilled in the art can design according to the actual situation and specific requirements, and this embodiment does not make specific limitations in this regard.

[0115] The structures of the cutting member 100 and the driving member 200 will be described in detail below.

[0116] As Figure 5 shown, the substrate cutting device 10 further includes a mounting frame 500 mounted on the tool holder 120, and a driving member 200 and a transmission member 300 are provided on the mounting frame 500. The cutting tool 110 is connected to the output end of the driving member 200 through the transmission member 300.

[0117] Among them, the transmission member 300 includes a guide member 310 disposed on the side of the cutting tool 110 facing away from the tool holder 120 and extending along the direction Z perpendicular to the surface of the substrate. The guide member 310 is adapted to be within a guide groove 320 extending along the direction Z perpendicular to the surface of the substrate on the mounting frame 500.

[0118] And, as Figure 5 shown, the transmission member 300 further includes an intermediate transmission unit 330. The input end of the intermediate transmission unit 330 is in transmission connection with the output end of the driving member 200, and the output end is in transmission connection with the guide member 310. The cutting tool 110 is linked to move along the direction Z perpendicular to the surface of the substrate through the guide member 310.

[0119] When this substrate cutting device 10 cuts the substrate, the driving member 200 drives the cutting tool 110 to move through the intermediate transmission unit 330 to transmit the power to the guide member 310. The guide member 310 assembled in the guide groove 320 can ensure that the cutting tool 110 moves along the direction Z perpendicular to the surface of the substrate, thereby cutting the substrate. This structure can utilize the cooperation between the guide member 310 and the guide groove 320 to limit the moving direction of the cutting tool 110, so that the cutting direction of the cutting tool 110 for the substrate is always perpendicular to the direction Z of the surface of the substrate, thereby improving the cutting accuracy.

[0120] Specifically, in this embodiment, the driving component 200 is set as a rotating motor 210. Regarding the model and specifications of the rotating motor 210, those skilled in the art can design according to the actual situation and specific requirements, and this embodiment does not make specific limitations on this.

[0121] Among them, as Figure 6 and Figure 7 shown, the intermediate transmission unit 330 includes a reducer 331 and an intermediate transmission member 350. The reducer 331 is connected to the rotating motor 210 by a belt drive, and an eccentric wheel shaft 332 is provided on the output shaft of the reducer 331. A connecting member 340 is connected to the end of the eccentric wheel shaft 332. The connecting member 340 is connected to the intermediate transmission member 350, and the intermediate transmission member 350 is fixedly connected to the guiding member 310. It should be noted that the belt for the transmission between the reducer 331 and the rotating motor 210 is covered by a protective cover to prevent the belt from being affected by external impurities during the transmission process.

[0122] The eccentric wheel shaft 332 rotates and drives the intermediate transmission member 350 and the guiding member 310 to move in the direction Z perpendicular to the surface of the substrate through the connecting member 340.

[0123] When this substrate cutting device 10 cuts the substrate, the power of the rotating motor 210 is output to the reducer 331. The eccentric wheel shaft 332 on the reducer 331 rotates and drives the intermediate transmission member 350 and the guiding member 310 to move in the direction Z perpendicular to the surface of the substrate through the connecting member 340. The reducer 331 plays a role of reducing speed and increasing torque to ensure that the acting force transmitted to the cutter 110 is sufficient for the cutter 110 to cut the substrate. By cooperating with the intermediate transmission member 350 through the connecting member 340, the rotation of the eccentric wheel shaft 332 is converted into the movement of the guiding member 310 in the direction Z perpendicular to the surface of the substrate, and the cutter 110 is driven by the guiding member 310 to perform cutting.

[0124] More specifically, as Figure 6 and Figure 7 shown, in this embodiment, the connecting member 340 is provided with a plate-like structure, and one side wall surface of the connecting member 340 is connected to the eccentric wheel shaft 332, and a limiting groove 341 extending in the direction parallel to the surface of the substrate is formed on the other side wall surface. A limiting guide rail 351 adapted to the limiting groove 341 is formed on the corresponding side wall of the intermediate transmission member 350. It should be noted that the length of the limiting groove 341 must be greater than the rotation diameter of the eccentric wheel shaft 332 around the center.

[0125] Therefore, the limiting groove 341 on the connecting member 340 cooperates with the limiting guide rail 351 on the intermediate transmission member 350. On the one hand, when the eccentric wheel shaft 332 rotates, the connecting member 340 can move relative to the intermediate transmission member 350 in a direction parallel to the surface of the substrate. Under the linkage of the connecting member 340, the intermediate transmission member 350 moves along the extension direction of the guiding groove 320, that is, in the direction Z perpendicular to the surface of the substrate, thereby driving the cutter 110 to perform cutting. On the other hand, it also plays a role in limiting the connecting member 340, preventing the connecting member 340 provided on the eccentric wheel shaft 332 from shaking.

[0126] This structure cleverly utilizes the cooperation of two sets of sliding members (the guiding member 310 and the guiding groove 320, the limiting groove 341 and the limiting guide rail 351) to realize the conversion of the rotation of the eccentric wheel shaft 332 into the translation of the cutter 110 in the direction Z perpendicular to the surface of the substrate. Compared with using a linkage rod to transmit the power of the eccentric wheel shaft 332 to the cutter 110, the transmission method using sliding members has less wear and is more reliable, thus extending the service life of the transmission component 300.

[0127] In another embodiment, the driving component 200 is set as a component that outputs power linearly, such as a linear motor. The output end of the linear motor is directly connected to the end of the guiding member 310 away from the cutter 110, and the guiding member 310 and the cutter 110 are driven by the linear motor. Of course, it can also be a cylinder that outputs power linearly, and the present invention does not make a unique limitation on this.

[0128] Furthermore, as Figure 4 shown, in this embodiment, the surface of the cutter 110 facing the tool holder 120 is a plane, and the surface of the tool holder 120 facing the cutter 110 is formed with a cutting groove 121 adapted to the edge of the cutter 110.

[0129] Moreover, the substrate cutting device 10 further includes a cutter guiding portion 130 spaced from the tool holder 120 in the direction Z perpendicular to the surface of the substrate. A cutter guiding groove 131 adapted to the cutter 110 is formed on the cutter guiding portion 130, and the cutter 110 is slidably disposed in the cutter guiding groove 131 in the direction Z perpendicular to the surface of the substrate.

[0130] Wherein, one end of the cutter guiding portion 130 is connected to the corresponding end of the tool holder 120, and a cutting channel 101 is formed between the opposite end faces of the tool holder 120 and the cutter guiding portion 130.

[0131] In this embodiment, since the surface of the cutter holder 120 facing the cutter 110 is formed with a cutting groove 121 adapted to the edge of the cutter 110, when the cutter 110 moves toward the cutter holder 120 to cut the substrate, it can be embedded in the cutting groove 121, thereby ensuring that the portion to be cut is separated from the substrate as a whole. In addition, the cutter guide groove 131 on the cutter guide portion 130 can further guide the moving direction of the cutter 110 and improve the cutting accuracy of the cutter 110.

[0132] In addition, if Figure 8 As shown, the substrate cutting device 10 for bag forming equipment provided by the utility model further includes a follower component 600, which is transmission-connected to the knife holder 120 and moves along the transport direction Y with the knife holder 120.

[0133] The follower assembly 600 includes a follower motor 610, a transmission screw 620 and a follower guide rail 630 along the transport direction Y. The follower motor 610 and the transmission screw 620 are connected by belt transmission. It should be noted that the belt transmitted between the follower motor 610 and the transmission screw 620 is also covered by a protective cover to prevent the belt from being affected by external impurities during the transmission process.

[0134] In addition, the bottom of the knife seat 120 is provided with a connecting block 122 matched with the follower screw and a slider 123 slidably connected with the follower guide rail 630. Specifically, the connecting block 122 has a threaded hole matched with the follower screw, and is sleeved on the follower screw through the threaded hole, and the connecting block 122 and the bottom of the knife seat 120 can be fixed by screw connection, clamping or other connection methods. Those skilled in the art can design according to actual conditions and specific needs, and this embodiment does not make specific limitations on this.

[0135] It should be noted that, due to the requirements of bag forming, the intervals between two adjacent cutting parts on the substrate are different, and the follower assembly 600 can be linked to move the knife seat 120 along the transport direction Y to adjust the position of the substrate cutting device 10 in the transport direction Y. In addition, since the screw drive has the advantage of high transmission accuracy, the power transmitted by the follower motor 610 is output to the knife seat 120 through the transmission screw, which can more accurately control the movement of the knife seat 120, and the follower guide rail 630 extending along the transport direction Y can guide the movement of the knife seat 120 through the slider 123 on the knife seat 120.

[0136] Furthermore, if Figure 9 As shown, in this embodiment, the substrate cutting device 10 further includes a waste collecting member 700. In the direction Z perpendicular to the surface of the substrate, the waste collecting member 700 is located on the side of the substrate away from the cutting member 100;

[0137] In the direction Z perpendicular to the surface of the substrate, the waste collection member 700 has a funnel-shaped structure that is recessed in the direction away from the cutting member 100, and a waste discharge port 710 is formed at the bottom of the waste collection member 700.

[0138] Among them, the waste collection member 700 disposed on the side of the substrate away from the cutting member 100 can, on the one hand, collect the cut waste, facilitating cleaning; on the other hand, prevent the waste from falling onto other components of the bag forming device and affecting the normal operation of other components.

[0139] Furthermore, the waste collection member 700 has a funnel-shaped structure that is recessed in the direction away from the cutting member 100, which can guide the waste falling into the waste collection member 700 to fall towards the waste discharge port 710 at the bottom, avoiding waste accumulation.

[0140] And, as Figure 4 shown, in this embodiment, a baffle 800 is provided on the downstream side of the tool holder 120 along the transport direction Y. The lower edge of the baffle 800 is aligned with the upper surface of the substrate passing through the cutting channel 101. On the one hand, it can further reduce the jitter of the substrate; on the other hand, it can prevent the cut waste from being transported along the transport direction Y.

[0141] As Figure 9 shown, when this substrate cutting device 10 is installed on the bag forming device, along the transport direction Y, the substrate cutting device 10 is disposed on the upstream side of the forming unit, and the tool holder 120 of the substrate cutting device 10 is disposed on the mounting plate 20. The mounting plate 20 is disposed on the frame (not shown) through the width adjustment guide rail 30. The position of the mounting plate 20 on the width adjustment guide rail 30 can be adjusted according to the cutting requirements, thereby changing the overlapping portion of the tool 110 and the tool holder 120 with the substrate in the direction perpendicular to the surface of the substrate, that is, adjusting the portion of the substrate to be cut by the tool 110, so that the substrate cutting device 10 can perform cutting according to requirements.

[0142] In summary, when this substrate cutting device 10 is installed on the bag forming equipment, the substrate transported along the transport direction Y first passes through the material stabilizing channel 401 between the first material stabilizing plate 410 and the second material stabilizing plate 420, thereby greatly reducing the jitter of the substrate, and then enters the cutting channel 101 between the cutting tool 110 and the tool holder 120. The rotation motor 210 transmits power to the reducer 331 through the belt. The reducer 331 outputs the power through the eccentric wheel shaft 332 and transmits it to the intermediate transmission member 350 through the connecting member 340. The connecting member 340 slides along a direction parallel to the transport direction Y relative to the intermediate transmission member 350, and drives the intermediate transmission member 350 and the guiding member 310 to move along the guiding groove 320. As a result, the cutting tool 110 is driven by the guiding member 310 to move towards the cutting groove 121 on the tool holder 120, so as to cut the substrate located between the cutting tool 110 and the cutting groove 121. Further, according to the cutting requirements, the follower member drives the tool holder 120 to move along the transport direction Y, and the cut waste will fall into the waste collection member 700 and be discharged from the waste discharge port 710.
