Description

Technical Field

[0001] The invention relates to the technical field of sheet material processing, in particular to a punching device. Background Art

[0002] The punching machine is a kind of mechanical equipment widely used in industrial production, mainly used for accurate punching, cutting or forming of materials. Specifically, the working principle of the punching machine is based on the principle of stamping, that is, the material placed on the working table of the equipment is punched through the die to make it plastically deformed or broken, so as to achieve the desired shape or size of the punching.

[0003] For example, paper tableware, especially knives, forks, spoons and other items, are made by pressing multiple layers of paper into paper sheets with a certain hardness, and then punching them into blanks of predetermined shapes before continuing with subsequent forming work.

[0004] The punching equipment in the prior art generally transports the sheet material horizontally to the bottom of the punching die through a conveyor belt, and then the punching die moves downward to cut the sheet material. The punched parts cut into predetermined shapes need to be collected manually immediately to avoid affecting subsequent punching.

[0005] This vertical punching machine is mainly suitable for stamping processing in the vertical direction. Its applicability is limited to workpieces that require bevel or complex shape stamping. In contrast, the horizontal punching machine can more easily adapt to stamping needs in different directions, so it has more advantages in processing complex workpieces.

[0006] However, when the horizontal punching machine is in use, the sheet needs to be unfolded in the vertical direction and placed on one side of the punching die. The sheet is only transported to the top of the punching die by a conveyor belt, and then hung on one side of the punching die in the horizontal direction. The punching accuracy of the punching die on the sheet cannot be guaranteed. Summary of the invention

[0007] In the prior art, the vertical punching machine is mainly suitable for stamping processing in the vertical direction. Its applicability is limited to workpieces that require bevel or complex shape stamping, and the blanks formed by the vertical punching machine are not easy to store. The horizontal punching machine transports the sheet to the top of the punching die through a conveyor belt, and then hangs the sheet on one side of the punching die in the horizontal direction, which cannot guarantee the punching accuracy of the punching die on the sheet.

[0008] To this end, an embodiment of the present invention provides a blanking device, including a frame, and a material guiding component, a blanking component and a discharging component arranged on the frame. The material guiding component is used to transport the sheet material to move along the feeding direction, and has a material guiding channel for transporting the sheet material along the feeding direction. The blanking component and the discharging component are located on the downstream side of the material guiding channel and are arranged at intervals in the horizontal direction. A blanking channel extending in the vertical direction is formed between the blanking component and the discharging component. The downstream end of the material guiding channel is smoothly connected to the inlet end of the blanking channel. Therefore, this blanking device transports the sheet material smoothly to the blanking channel through the material guiding channel of the material guiding component. The blanking component moves toward the sheet material maintaining a stable posture in the blanking channel to cut out the blanking piece of a predetermined shape and transport it to the discharging component. During the blanking process, the process of transferring the blanking piece to the discharging component is completed at the same time. Then the new sheet material is transported to the blanking channel for the next blanking.

[0009] Moreover, in the present embodiment, the material guiding component also includes a traction assembly and a retaining assembly arranged beside the material guiding channel. The traction assembly drives the sheet material to move along the material guiding channel, and the sheet material is retained in the material guiding channel by the retaining assembly, thereby preventing the sheet material from shaking unexpectedly (i.e., deviating from the feeding direction), thereby improving the transportation stability of the sheet material.

[0010] The blanking component includes a blanking die and a discharge plate which are located on both sides of the blanking channel in the horizontal direction and are relatively adapted to each other; wherein the blanking die is located on the side away from the discharge component relative to the blanking channel and is detachably installed on the driving end of the blanking drive assembly in the frame, and the blanking drive assembly drives the blanking die to move in the horizontal direction; the discharge plate is vertically extended and fixed on the frame, on one side close to the discharge component, and the discharge plate is opposite to the end face of the blanking die and has a discharge hole of a predetermined shape; and the discharge component is extended in the horizontal direction and is arranged on the side of the discharge plate away from the blanking channel, corresponding to the discharge hole, and has a storage channel adapted to the blanking part of the predetermined shape.

[0011] During use, the punching drive assembly drives the punching die to move in the horizontal direction, thereby cutting the sheet material located in the punching channel. Part of the sheet material will be cut into punched parts of predetermined shapes, and discharged from the discharge hole of the discharge plate and transported to the storage channel. The storage channel can neatly store the punched parts produced by multiple punching processes, which is convenient for subsequent handling. There is no need for manual sorting and stacking of the punched parts, thereby reducing labor costs and improving production efficiency.

[0012] In summary, the punching equipment provided by the present invention can quickly and accurately cut the sheet material multiple times through the cooperation of the material guiding parts, punching parts and discharging parts arranged on the frame, and the cut punched parts will be neatly stored, which greatly improves the work efficiency of punching the sheet material.

[0049] The horizontal punching machine in the prior art transports the sheet material to the top of the punching die through a conveyor belt, and then makes the sheet material hang on one side of the punching die in the horizontal direction, which cannot ensure the punching accuracy of the punching die on the sheet material.

[0050] To this end, the present invention provides a blanking device, which includes a frame, and a material guiding component, a blanking component and a discharging component arranged on the frame. The material guiding component is used to transport the sheet material to move along the feeding direction, and has a material guiding channel for transporting the sheet material along the feeding direction. The blanking component and the discharging component are located on the downstream side of the material guiding channel and are arranged at intervals in the horizontal direction. A blanking channel extending in the vertical direction is formed between the blanking component and the discharging component. The downstream end of the material guiding channel is smoothly connected to the inlet end of the blanking channel. Therefore, this blanking device smoothly transports the sheet material to the blanking channel through the material guiding channel of the material guiding component. The blanking component moves toward the sheet material maintaining a stable posture in the blanking channel to cut out the blanking piece of a predetermined shape and transport it to the discharging component, and then transports the new sheet material to the blanking channel for the next blanking. This blanking device improves the work efficiency of blanking the sheet material while ensuring the blanking accuracy.

[0051] To make the objectives, technical solutions and advantages of the present invention more clear, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0052] like Figure 1-Figure 3 As shown, an embodiment of the present invention provides a punching device 10, including a frame 100, and a material guiding component 200 arranged on the frame 100 for conveying sheet materials, a punching component 300 for punching sheet materials, and a discharge component 400 for storing punched parts cut into predetermined shapes.

[0053] Among them, the material guiding component 200 has a material guiding channel for transporting the sheet material along the feeding direction, and the material guiding component 200 also includes a traction component 220 and a retaining component 230 arranged beside the material guiding channel. The traction component 220 drives the sheet material to move along the material guiding channel, and the sheet material is retained in the material guiding channel by the retaining component 230, so as to avoid unexpected shaking of the sheet material (i.e., deviating from the feeding direction) and improve the transportation stability of the sheet material.

[0054] The blanking component 300 includes a blanking die 310 and a discharge plate 320 which are located on both sides of the blanking channel in the horizontal direction and are relatively adapted to each other; wherein the blanking die 310 is located on the side away from the discharge component 400 relative to the blanking channel and is detachably installed on the driving end of the blanking drive assembly 330 in the frame 100, and the blanking drive assembly 330 drives the blanking die 310 to move in the horizontal direction; the discharge plate 320 is vertically extended and fixed on the frame 100, close to the side of the discharge component 400, and the discharge plate 320 is opposite to the end face of the blanking die 310 and has a discharge hole 321 of a predetermined shape; and the discharge component 400 is extended in the horizontal direction and is arranged on the side of the discharge plate 320 away from the blanking channel, at a position corresponding to the discharge hole 321 and has a storage channel adapted to the blanking parts of the predetermined shape.

[0055] During use, the sheet material enters the material guide channel from the upstream end of the material guide channel and is held in the material guide channel by the retaining component 230. The traction component 220 pulls the sheet material to move along the material guide channel and enters the punching channel through the downstream end of the material guide channel. The punching drive component 330 drives the punching die 310 to move in a horizontal direction, thereby cutting the sheet material in the punching channel. Part of the sheet material will be cut into punching parts of predetermined shapes and discharged from the discharge hole 321 of the discharge plate 320 and transported to the storage channel. The storage channel can neatly store the punching parts produced by multiple punching processes, which is convenient for subsequent handling. There is no need for manual sorting and stacking of the punching parts, which reduces labor costs and improves production efficiency.

[0056] It should be noted that the sheet material processed by the punching device 10 can be a sheet structure made of soft materials such as paper, paper-like materials, plastic, etc., or a sheet structure made of metal with good ductility. This embodiment does not make any specific limitations on this.

[0057] Furthermore, after the sheet material is punched out, a punched piece of a predetermined shape is formed. The shape of the punched piece is related to the specific product to be processed. For example, if the product to be processed is a fork in tableware, the shape of the punched piece is adapted to the shape of the fork. For another example, if the product to be processed is a spoon in tableware, the shape of the punched piece is adapted to the shape of the spoon. This embodiment does not make any specific limitation on this.

[0058] Next, the individual components of the punching device 10 will be described.

[0059] For ease of explanation, a paper sheet structure is used as an example for explanation below. Paper sheets can be used to produce disposable tableware, such as knives, forks, spoons and the like. In order to ensure that the tableware produced from paper has a high structural strength, multiple layers of paper are usually composited and pressed into sheets of a certain thickness, and then punched. That is, the sheet punched by the punching device 10 is not necessarily a single sheet of paper, but may also be a sheet of multiple layers of paper stacked together. Regarding the structure of pressing and compounding multiple layers of paper, this embodiment does not make any specific limitation on this.

[0060] First, the frame 100 of the punching equipment 10 will be described in detail.

[0061] like Figure 1-Figure 3 As shown, the frame 100 serves as a supporting structure of the entire punching device 10 , and needs to provide installation locations for the material guiding component 200 , the punching component 300 , and the material discharging component 400 , and ensure the placement stability of the entire punching device 10 .

[0062] Optionally, in one embodiment, the frame 100 includes a base 110 and a pair of installation walls 120 disposed on the base 110 and spaced apart, and the material guide component 200, the punching component 300, and the material discharge component 400 are all located between the pair of installation walls 120. The upper surface of the base 110 can be fixed to the installation wall 120 at the corresponding position by screwing, welding, or clamping, and the lower surface is abutted against a flat placement platform to improve the placement stability. The placement platform can be the ground or the table top of a stand, and the present invention does not specifically limit this.

[0063] Furthermore, in order to prevent the sheet material from accumulating in the punching device 10, a waste discharge port aligned with the lower end of the punching channel is formed on the base 110 below the punching channel. The remaining part (i.e., the waste material) after being punched in the punching channel will be discharged from the lower port of the punching channel and then discharged from the punching device 10 from the waste discharge port of the base 110.

[0064] Specifically, in this embodiment, the waste discharge port is set as a rectangular opening on the base 110. The four corners of this rectangular opening are rounded, and the shape is regular and easy to process while facilitating the discharge of waste. Of course, the waste discharge port can also be set as an elliptical opening or a shuttle-shaped opening, and this embodiment does not make the sole limitation to this.

[0065] The specific structure of the frame 100 is not limited to the structure in the above embodiment. For example, in another alternative embodiment, the frame 100 is formed by splicing multiple groups of frame beams, for example, two groups of frame beams are arranged at intervals along the vertical direction, wherein the frame beams located at the upper part are used to assemble the material guiding parts 200, and the frame beams located at the lower part are used to assemble the punching parts 300 and the discharging parts 400. The specific structure can be designed by those skilled in the art according to actual conditions and specific needs, and this embodiment does not make specific limitations on this.

[0066] Therefore, the structure of the frame 100 may be formed by overlapping a plurality of plates, or may be formed by splicing a plurality of frame beams, and the embodiments of the present invention do not make any sole limitation to this.

[0067] Next, the material guide member 200 of the punching equipment 10 will be described.

[0068] like Figure 4 and Figure 5 As shown, the material guide component 200 is used to transport the sheet material along the feeding direction. In order to form a material guide channel for stable transportation of the sheet material, at least one material guide plate 210 can be used to form the wall of the material guide channel, or a through hole penetrating the solid structure can be set to form the material guide channel. This embodiment does not make a sole limitation on this.

[0069] Optionally, in one embodiment, Figure 5 As shown, the material guiding component 200 includes a material guiding plate 210 arranged above the punching component 300, and the upper surface of the material guiding plate 210 constitutes the bottom wall of the material guiding channel. The material guiding component 200 also includes a traction component 220 and a retaining component 230 arranged beside the material guiding plate 210. The traction component 220 drives the sheet material to move along the material guiding channel, and the sheet material is retained in the material guiding channel by the retaining component 230, so as to avoid unexpected shaking of the sheet material (i.e., deviation from the feeding direction), thereby improving the transportation stability of the sheet material.

[0070] It should be noted that, in general, the sheet material is generally transported to the punching device 10 in a horizontal direction, and the sheet material needs to be converted to a vertical direction in the material guide channel until it enters the punching channel extending in the vertical direction. Since the sheet material may be composed of multiple layers of paper materials, it has a certain strength and is not easy to bend 90 degrees. Moreover, a 90-degree bend may generate greater resistance, affecting the traction of the sheet material. For this reason, in one embodiment, Figure 4As shown, the guide plate 210 has a first guide section 211, a transition section 212 and a second guide section 213 in sequence along the feeding direction. The first guide section 211 extends downwardly at an inclination relative to the horizontal direction, and the lower end is connected to the upper end of the transition section 212. The second guide section 213 extends in the vertical direction, and the lower end is aligned with the side of the punching channel close to the punching component 300. The transition section 212 is smoothly curved, and the lower end is connected to the upper end of the second guide section 213.

[0071] In this embodiment, the sheet material is pulled by the pulling assembly 220, and enters the guide plate 210 from the upstream end of the first guide section 211, and is transported in sequence along the first guide section 211, the transition section 212, and the second guide section 213, so that the sheet material transported in the horizontal direction is smoothly turned to the vertical direction, so as to facilitate entering the punching channel for subsequent punching. The sheet material on the guide plate 210 will not be bent significantly, which, on the one hand, reduces the risk of damage to the sheet material during transportation; on the other hand, reduces the difficulty of pulling the sheet material to move.

[0072] Furthermore, since the guide plate 210 only abuts against the lower surface of the sheet, when the sheet is transported to the transition section 212, it is possible for the sheet to separate from the outer surface of the guide plate 210, and the retaining component 230 can prevent this from happening.

[0073] Alternatively, if Figure 5 As shown, in one embodiment, the traction assembly 220 includes a traction roller group arranged at the downstream end of the material guide channel, the traction roller group includes a pair of traction rollers 221 arranged opposite to each other on both sides of the thickness direction of the sheet, and a traction driving member 222 drivingly connected to any one of the pair of traction rollers 221, a roller gap adapted to the thickness direction of the sheet is formed between the pair of traction rollers 221 to ensure that the sheet can be tightly clamped between the pair of traction rollers 221, when the sheet moves to the roller gap between the pair of traction rollers 221, the wall surfaces of the pair of traction rollers 221 close to each other will abut against both sides of the sheet in the thickness direction, when the traction rollers 221 are driven to rotate by the traction driving member 222, the traction rollers 221 will drive the sheet located between the pair of traction rollers 221 to move along the feeding direction. This traction assembly 220 cleverly converts the rotation of the traction roller group into the translation of the sheet along the transportation direction, and can continuously traction the sheet to move.

[0074] In one embodiment, the traction drive member 222 is fixed on the frame 100, and is drivingly connected to one end of a traction roller 221 of a pair of traction rollers 221 that is away from the discharge part 400, and the other end of one traction roller 221 is drivingly connected to the corresponding end of the other traction roller 221 through an adjustable transmission gear set 2221. It should be noted that the traction drive member 222 can be a rotary motor commonly used in the art. Regarding the model and specification of the rotary motor, those skilled in the art can design it according to actual conditions and specific needs, and this embodiment does not specifically limit this.

[0075] In this embodiment, one end of a traction roller 221 (which can be called "active roller") away from the discharge part 400 is connected to the traction drive 222. When the traction drive 222 is working, it will directly drive the active roller to start rotating. The other traction roller 221 (which can be called "driven roller") is not directly driven by the traction drive 222. On the contrary, the other end of the driven roller (the end opposite to the active roller) is connected to the corresponding end of the active roller through a gear set. When the active roller is driven to rotate by the traction drive 222, the active roller transmits power to the driven roller through the adjustable transmission gear set 2221. Since the transmission ratio of the adjustable transmission gear set 2221 is fixed (but adjustable within a certain range), the active roller and the driven roller will rotate at the same speed (or at a certain ratio of speed). In this way, a pair of traction rollers 221 can synchronously drive the sheet material to move along the feeding direction. Since the sheet material is pulled by the traction rollers 221 on both sides of the thickness, the force is even, so it is not easy to generate wrinkles.

[0076] In another embodiment, the traction drive member 222 is connected to any one of the pair of traction rollers 221 (i.e., the active roller). When the traction drive member 222 drives the active roller to rotate, since the active roller and the driven roller are in contact with each other through the sheet, when the active roller rotates, the driven roller will also be affected by the friction of the sheet and start to rotate. In this way, the pair of traction rollers 221 will jointly drive the sheet between them to move along the feeding direction.

[0077] Furthermore, in one embodiment, the other traction roller 221 of a pair of traction rollers 221, which is closer to the discharge component 400, includes a movable roller shaft 223 and a traction sleeve 224 sleeved on the movable roller shaft 223. The movable roller shaft 223 will link the traction sleeve 224 to rotate, and the traction sleeve 224 cooperates with the other traction roller 221 to clamp and transport the sheet material. The outer surface of the traction sleeve 224 has a large friction coefficient, or a plurality of protrusions are provided on the outer surface of the traction sleeve 224 to increase the friction between the traction sleeve 224 and the sheet material, thereby facilitating the traction of the sheet material. This design does not require the outer surface of the movable roller shaft 223 to contact the sheet material, and has a lower requirement on the processing accuracy of the outer surface of the movable roller shaft 223, thereby reducing costs.

[0078] Specifically, in this embodiment, the movable roller 223 is provided with two traction sleeves 224 at intervals along its axial direction, and the spacing between the two traction sleeves 224 is adapted to the width of the sheet material, ensuring that the two traction sleeves 224 can act on the sheet material. Of course, in order to adapt to sheets of different widths, on the movable roller 223, corresponding positions of the two traction sleeves 224 form strip holes extending along the axial direction, and the traction sleeves 224 are assembled on the movable roller 223 through the corresponding strip holes, and the spacing between a pair of traction sleeves 224 can be changed by manually connecting the position of the traction sleeves 224 on the strip holes.

[0079] Further, if Figure 6 As shown, both ends of the movable roller shaft 223 are movably arranged in the horizontal direction in the corresponding slide groove 121 extending in the horizontal direction on the corresponding mounting wall 120 through the slider 225. By adjusting the position of the slider 225 in the slide groove 121, the gap between the pair of traction rollers 221 can be adjusted to ensure that when processing sheets of different thicknesses, they can all be clamped in the roller gap of the pair of traction rollers 221, and the immovable traction roller 221 plays a positioning role.

[0080] Of course, the method for adjusting the position of the slider 225 in the slide groove 121 can be to push the slider 225 for adjustment by a slider adjustment member 226 (such as a motor or a cylinder) acting on the slider 225 through the output end, or to manually change the position of the slider 225 in the slide groove 121. This embodiment does not make a sole limitation on this.

[0081] Of course, in order to increase the traction force on the sheet material, the traction assembly 220 not only includes a traction roller group arranged at the downstream end of the material guide channel, but also another traction roller group can be arranged at the upstream end of the material guide channel. Its structure is similar to that of the traction roller group arranged at the downstream end of the material guide channel, and will not be repeated here.

[0082] Further, in this embodiment, if Figure 5As shown, the retaining assembly 230 includes a pressure roller 231 arranged opposite to the first guide section 211; wherein the pressure roller 231 includes a pressure roller 231 shaft rotatably arranged on the mounting wall 120, and a pressure sleeve 232 sleeved on the roller shaft, and a retaining gap is formed between the pressure sleeve 232 and the upper surface of the corresponding guide plate 210.

[0083] Specifically, the axis of the pressure roller 231 is the main part of the pressure roller 231, which is rotatably arranged on the mounting wall 120, which means that the axis of the pressure roller 231 can rotate freely on the frame 100, thereby allowing the pressure roller 231 to roll above the material, and the pressure sleeve 232 is sleeved on the axis of the pressure roller 231 to directly contact the sheet material.

[0084] When the sheet material is transmitted on the first material guide section 211, the pressing roller 231 shaft applies a certain pressure to the material through the pressing sleeve 232 to keep the material on the first material guide section 211, thereby preventing the material from deflecting or falling during the transmission process.

[0085] At the same time, since the pressing roller 231 is rotatable, the pressing sleeve 232 will not cause excessive friction resistance to the material, thereby ensuring the smoothness of material transmission. The pressing sleeve 232 sleeved on the pressing roller 231 shaft is similar in structure to the traction sleeve 224 sleeved on the movable roller shaft 223. A pair of pressing sleeves 232 can also be arranged on the pressing roller 231 shaft at intervals along the axial direction, and the assembly structure between the pressing roller 231 shaft and the pressing sleeve 232 is also similar to the assembly structure between the movable roller shaft 223 and the traction sleeve 224, which will not be repeated here.

[0086] However, during transportation, the power transmission between the two and the sheet material is different. The traction sleeve 224 mounted on the movable roller shaft 223 drives the sheet material forward along the feeding direction through its own rotation, while the clamping sleeve 232 mounted on the shaft of the clamping roller 231 is driven to rotate by the sheet material.

[0087] Furthermore, both ends of the axis of the pressing roller 231 are vertically movably disposed on the frame 100. Specifically, Figure 7 As shown, a pair of mounting grooves 122 extending in the vertical direction are formed at corresponding positions on the frame 100 and at the lower end of the first guide section 211. Both ends of the axis of the pressure roller 231 can be horizontally slidably arranged in the corresponding mounting grooves 122 through mounting blocks 233. By adjusting the position of the mounting block 233 in the mounting groove 122, the gap between the pressure roller 231 and the guide plate 210 can be adjusted to ensure that when processing sheets of different thicknesses, they can all be clamped in the gap between the pressure roller 231 and the guide plate 210.

[0088] Of course, the method for adjusting the position of the mounting block 233 in the mounting groove 122 can be by manually changing the position of the mounting block 233 in the mounting groove 122, or by pushing the mounting block 233 for adjustment through a mounting block adjustment member (such as a motor or a cylinder) acting on the mounting block 233 through the output end. This embodiment does not make a sole limitation on this.

[0089] Of course, if the transport distance of the guide plate 210 is long, not only can a clamping roller 231 be set at the corresponding position of the first guide section 211, but also multiple clamping rollers 231 can be set at the corresponding positions of the transition section 212 or the second guide section 213. The present invention does not make a sole limitation on this.

[0090] Generally, the width of the guide plate 210 needs to be greater than or equal to the width of the sheet. When the width of the guide plate 210 is greater than the width of the sheet, the sheet may deviate in the width direction during transportation. Figure 5 As shown, the material guide component 200 also includes a plurality of pairs of sheet material limiting components 240 arranged on the frame 100 and spaced apart along the feeding direction. Specifically, one pair, two pairs, three pairs or other number of sheet material limiting components 240 may be arranged along the feeding direction, and those skilled in the art may design them according to actual conditions and specific requirements, and this embodiment does not specifically limit this.

[0091] Specifically, each pair of sheet material limiting assemblies 240 are spaced apart in the width direction of the sheet material, and limiting portions 241 adapted to the side edges of the sheet material are respectively formed on the side walls opposite to each other. The edges on both sides of the width direction of the sheet material transported in the material guiding channel cooperate with the limiting portions 241 respectively, thereby limiting the shaking of the sheet material in the width direction.

[0092] Optionally, in one embodiment, each limiting assembly includes a mounting rod 242 movably mounted on the frame 100 along the width direction of the sheet, and a limiting wheel 243 sleeved on the mounting rod 242, the limiting portion 241 is a circumferential limiting groove 244 on the side wall of the limiting wheel 243, and a pair of limiting wheels 243 clamp the edges of the corresponding sides of the sheet through the circumferential limiting groove 244 on the side walls.

[0093] Among them, a plurality of pairs of sheet material limiting components 240 are sequentially arranged at intervals on the upstream side of the material guide plate 210 and arranged in the material guide channel along the extension direction of the material guide plate 210, so as to ensure that the deviation of the sheet material in the width direction is always limited during transportation. It should be noted that the sheet material limiting components 240 arranged in the material guide channel extend into the material guide channel from the corresponding position of the material guide plate 210, so as to limit the sheet material in the material guide channel.

[0094] In one embodiment, two pairs of sheet material limiting components 240 are arranged at intervals along the feeding direction on the frame 100. One pair of sheet material limiting components 240 is located on the upstream side of the material guide plate 210, and the other pair of sheet material limiting components is arranged in the material guide channel, located in the second material guide section 213.

[0095] Specifically, a connecting rod 123 is provided between a pair of mounting walls 120 and located on the upstream side of the guide plate 210, and a pair of mounting rods 242 of sheet material limiting assemblies 240 are connected to the connecting rod 123, thereby being arranged on the upstream side of the guide plate 210, and the circumferential limiting groove 244 of the limiting wheel 243 is parallel to the first guide plate 210 of the guide plate 210.

[0096] Another connecting rod 123 is provided on the inner side of the second material guide plate 210 between the pair of mounting walls 120, and the mounting rods 242 of the other pair of sheet material limiting assemblies 240 are connected to the connecting rod 123. The second material guide plate 210 of the material guide plate 210 forms a mounting hole 214 corresponding to the limiting wheel 243 at a corresponding position of the sheet material limiting assembly 240, and the circumferential limiting groove 244 of the limiting wheel 243 of the sheet material limiting assembly 240 extends from the mounting hole 214 from the inner side of the material guide plate 210. It should be noted that the position of the mounting rods 242 of the pair of sheet material limiting assemblies 240 on the connecting rod 123 is adjustable to accommodate sheets of different widths.

[0097] Of course, the setting positions of multiple pairs of sheet material limiting components 240 are not limited to the positions in the above-mentioned embodiments. In another alternative embodiment, at least one pair of sheet material limiting components 240 are set in the first guide section 211 and the second guide section 213 of the guide plate 210. A pair of sheet material limiting components 240 can also be set between the guide channel and the punching channel. Those skilled in the art can design according to actual conditions and specific needs, and this embodiment does not make any specific limitations on this.

[0098] In addition, since the transport speed of the sheet from the outside to the punching device 10 may be inconsistent with the transport speed of the sheet in the material guide channel, for example, the transport speed from the outside to the punching device 10 is greater than the transport speed of the sheet in the material guide channel, the sheet will be accumulated at the entrance end of the material guide channel, and the transport speed from the outside to the punching device 10 is less than the transport speed of the sheet in the material guide channel, the sheet at the entrance end of the material guide channel is tightened and may even be pulled to produce cracks. Therefore, in one embodiment, if Figure 5 As shown, a sheet tensioning roller 250 rotatably disposed on the frame 100 is also provided on the upstream side of the guide plate 210. In the feeding direction, the sheet tensioning roller 250 is located between the sheet limiting assembly 240 on the upstream side of the guide plate 210 and the upstream end of the guide plate 210.

[0099] Specifically, both ends of the sheet tensioning roller 250 are respectively mounted on the corresponding mounting wall 120. The sheet tensioning roller 250 applies a certain tension to the sheet through its rotation and contact with the sheet, and this tension helps to keep the sheet flat and stable, and prevent it from being loose or wrinkled during the transmission process. In addition, the sheet tensioning roller 250 can also position the sheet to ensure that it is in the correct position and angle when entering the guide plate 210.

[0100] Next, the punching member 300 of the punching equipment 10 will be described.

[0101] like Figure 8 As shown, the blanking component 300 includes a blanking die 310 and a discharge plate 320 which are located on both sides of the blanking channel in the horizontal direction and are relatively adapted to each other; wherein, the blanking die 310 is located on the side away from the discharge component 400 relative to the blanking channel and is detachably mounted on the driving end of the blanking drive assembly 330 in the frame 100, and the blanking drive assembly 330 drives the blanking die 310 to move in the horizontal direction; the discharge plate 320 is vertically extended and fixed on the frame 100, close to one side of the discharge component 400, and the discharge plate 320 is opposite to the end face of the blanking die 310 and has a discharge hole 321 of a predetermined shape. It should be noted that the shape of the discharge hole 321 is determined by the blanking piece to be cut, and can be the shape of a fork, spoon or knife in tableware.

[0102] Specifically, the punching drive assembly 330 includes a punching drive member 331, a punching transmission mechanism 332, and a mounting seat 333. The punching transmission mechanism 332 connects the punching drive member 331 and the mounting seat 333. The mounting seat 333 acts as a driving end of the punching drive assembly 330 to link the punching die 310 to move in the horizontal direction. It should be noted that the punching drive member 331 can be a driving motor commonly used in the art. The model and specification of the driving motor are not specifically limited in this embodiment.

[0103] And, if Figure 8 and Fig. 9 As shown, the frame 100 is also provided with a guide assembly 340 which is connected to the mounting seat 333 and extends in a horizontal direction.

[0104] During use, the punching drive member 331 drives the punching drive mechanism 332 and the linkage mounting seat 333 to drive the punching die 310 to reciprocate along the extending direction of the guide assembly 340 .

[0105] In one embodiment, the mounting seat 333 is configured as a plate-like structure, which is fixed to the side of the punching die 310 facing away from the discharge plate 320 by means of screw connection, clamping connection or locking pin connection. Since different punching dies 310 need to be replaced for different punching parts, a detachable connection is generally adopted between the mounting seat 333 and the punching die 310.

[0106] Furthermore, since the punching die 310 itself is heavy, in order to reduce the load of the punching drive member 331 , a weight-reducing hole may be provided on the mounting seat 333 .

[0107] As mentioned above, different punching dies 310 need to be replaced for different punching parts. In order to more conveniently replace the punching dies 310, in the horizontal direction, a pair of mounting walls 120 are provided with a die changing channel beside the punching channel. The replaced punching die 310 can be removed and transported to the outside from the die changing channel, and then the punching die 310 to be replaced can be transported from the die changing channel to the corresponding installation position of the mounting seat 333.

[0108] Furthermore, since the mass of the punching die 310 is relatively large, in order to reduce the labor intensity of the workers, such as Fig.10 As shown, an auxiliary mold changing assembly 130 is formed on the outside of at least one installation wall 120 and the outside of the corresponding position of the mold changing channel.

[0109] Specifically, the auxiliary mold changing assembly 130 includes a support frame 131 installed on the outer side of the installation wall 120 and flush with the lower side of the mold changing channel. On the support frame 131, a plurality of groups of support rods 132 are arranged at intervals along the extension direction of the mold changing channel. The number of support rods 132 can be two groups, three groups, six groups, seven groups or other numbers, and this embodiment does not make any specific limitation on this.

[0110] The support frame 131 is installed on the outside of the installation wall 120. This position selection ensures that the support frame 131 can stably support the mold without hindering the normal replacement operation of the mold. In addition, the lower side of the support frame 131 is flush with the lower side of the mold change channel. This design allows the punching mold 310 to be stably placed on the support frame 131 when replacing, avoiding shaking or tilting of the punching mold 310 due to height differences.

[0111] A plurality of groups of support rods 132 are arranged at intervals along the extension direction of the die changing channel, and each group of support rods 132 can be used to carry the punching die 310. Such spaced support rods 132 not only ensure the stability of the punching die 310 during the replacement process, but also can convert the sliding friction during the moving of the punching die 310 into rolling friction, greatly reducing the difficulty of carrying the punching die 310.

[0112] Furthermore, in order to improve the connection strength between the support frame 131 and the installation wall 120 , a reinforcing rib plate 133 is further provided between the lower side of the support frame 131 and the installation wall 120 to enhance the connection strength between the support frame 131 and the installation wall 120 .

[0113] Of course, in another embodiment, auxiliary die changing assemblies 130 are formed on the outside of a pair of mounting walls 120 and on the outside of the corresponding positions of the die changing channel, wherein the auxiliary die changing assembly 130 on one side is used to move the replaced punching die 310 out of the punching equipment 10, while the auxiliary die changing assembly 130 on the other side is used to move the new punching die 310 into the punching equipment 10, thereby improving the die changing efficiency.

[0114] In this embodiment, if Figure 8 As shown, the blanking transmission mechanism 332 includes a driving sprocket set 3320 and a driven sprocket set 3321 located between the driving sprocket set 3320 and the mounting seat 333 , and a tensioning sprocket set 3322 is further arranged between the driving sprocket set 3320 and the driven sprocket set 3321 .

[0115] The driving sprocket group 3320 includes a driving wheel shaft 3323 rotatably mounted on a pair of mounting walls 120 and a driving sprocket 3324 sleeved on the driving wheel shaft 3323, the tensioning sprocket group 3322 includes a tensioning sprocket 3327 rotatably mounted on the frame 100, the driven sprocket group 3321 includes a driven wheel shaft 3325 rotatably mounted on the frame 100 and a driven sprocket 3326 sleeved on the driven wheel shaft 3325, the two ends of the transmission chain are respectively sleeved on the driving sprocket 3324 and the driven sprocket 3326, and the tensioning sprocket 3327 is located in the middle of the transmission chain. The tensioning sprocket 3327 is used to adjust the tension of the transmission chain to ensure that the chain maintains an appropriate tightness during the transmission process, and avoid poor transmission or damage caused by the chain being too loose or too tight.

[0116] The output end of the punching drive member 331 is connected to the driving wheel shaft 3323 through a reducer 3328 installed on the base 110. An eccentric connecting arm 3329 is sleeved on the driven wheel shaft 3325. The free end of the connecting arm is connected to the end of the mounting seat 333 away from the punching die 310. The punching die 310 is fixed to the end of the mounting seat 333 away from the punching drive assembly 330.

[0117] In one embodiment, in order to improve the transmission efficiency and carrying capacity, a pair of driving sprockets 3324 are arranged on the driving wheel shaft 3323, the tensioning sprocket group 3322 includes a pair of tensioning sprockets 3327 respectively arranged on a pair of mounting walls 120, and a pair of driven sprockets 3326 are arranged on the driven wheel shaft 3325. The pair of driving sprockets 3324, the pair of tensioning sprockets 3327 and the pair of driven sprockets 3326 are respectively connected by two transmission chains.

[0118] And, if Fig. 9As shown, the guide assembly 340 includes a plurality of guide rods 341 arranged at intervals along the circumference of the mounting seat 333, one end of each guide rod 341 can be slidably arranged on the frame 100 along the horizontal direction, and the other end is fixedly connected to the side of the mounting seat 333 away from the punching die 310.

[0119] Specifically, four guide rods 341 are arranged at intervals along the circumference of the mounting seat 333, and the four guide rods 341 are respectively located at four angles of the mounting seat 333, and a connecting wall 140 is arranged between a pair of mounting walls 120 and located inside the mounting seat 333, and the connecting wall 140 is formed with guide holes at corresponding positions of the four guide rods 341, and each guide rod 341 is matched with a corresponding guide hole. In addition, in order to improve the support for the driven wheel shaft 3325, a support arm 141 for supporting the driven wheel shaft 3325 is also arranged on the connecting wall 140.

[0120] During the punching process, the power of the punching drive 331 is decelerated and torque-increased by the reducer 3328 and transmitted to the driving wheel shaft 3323. The driving wheel shaft 3323 rotates and transmits the power to the tensioning sprocket 3327 and the driven sprocket 3326 through the driving sprocket 3324 sleeved on the driving wheel shaft 3323. The driven sprocket 3326 drives the driven wheel shaft 3325 to rotate. When the driving wheel shaft rotates, the eccentric connecting arm 3329 swings and pushes the mounting seat 333 and the punching die 310 arranged on the mounting seat 333 to reciprocate along the extension direction of the multiple guide rods 341, thereby realizing the punching of the sheet.

[0121] It should be noted that the punching transmission mechanism 332 is not limited to the structure in the above embodiment. In another alternative embodiment, the punching transmission mechanism 332 includes a rack extending in the horizontal direction. A driving gear is arranged at the output end of the punching drive member 331. The driving gear is meshed with the driven gear, and the driven gear cooperates with the rack. One end of the rack is connected to the mounting seat 333. During the punching process, the punching drive member 331 drives the driving gear to rotate, and transmits the power to the rack through the driven gear, so that the rack drives the mounting seat 333 and the punching die 310 to move.

[0122] Alternatively, the punching transmission structure includes a screw extending in the horizontal direction, one end of which is fixedly connected to the mounting seat 333, and a transmission sleeve is arranged at the output end of the punching drive member 331. The transmission sleeve is sleeved on the screw, and the inner wall surface of the transmission sleeve has an internal thread that matches the external thread of the outer wall of the screw. The power of the punching drive member 331 is transmitted to the screw through the transmission sleeve, and the screw converts the rotational motion of the transmission sleeve into linear motion in the horizontal direction, thereby driving the mounting seat 333 and the punching die 310 to move.

[0123] Therefore, those skilled in the art may design the punching transmission mechanism 332 according to actual conditions and specific requirements, and the present invention does not make a sole limitation thereto.

[0124] Of course, in other embodiments, the punching drive component 331 can also be set as a cylinder, a hydraulic cylinder or a linear motor that outputs power in the horizontal direction, and the output end of the punching drive component 331 can be directly connected to the mounting seat 333, so that the mounting seat 333 and the punching die 310 can be directly driven to move in the horizontal direction through the punching drive component 331.

[0125] Further, if Fig.10 As shown, in this embodiment, in order to improve the stability of the sheet entering the punching channel, a guide plate 350 extending vertically to the traction roller 221 is provided at the entrance end of the punching channel to ensure that the sheet output from the material guide channel can enter the punching channel smoothly and accurately.

[0126] In addition, the outlet end of the punching channel is provided with a plurality of waste tensioning rollers 360 arranged in sequence along the vertical direction. The remaining part discharged from the lower end of the punching channel passes through at least two waste tensioning rollers 360 in sequence. The number of waste tensioning rollers 360 can be two, three or four, and this embodiment does not make a sole limitation on this.

[0127] The function of these waste tensioning rollers 360 is to guide and tension the waste, ensuring that the waste can maintain a certain tension and directionality during the discharge process, avoiding entanglement, knotting or disorderly scattering, improving the efficiency of waste treatment, and ensuring the cleanliness and safety of the working environment.

[0128] Finally, the discharge member 400 of the punching device 10 will be described.

[0129] like Fig.10 and Fig.11 As shown, the discharge component 400 is extended in the horizontal direction and is arranged on the side of the discharge plate 320 away from the punching channel and at a position corresponding to the discharge hole 321 and has a storage channel adapted to the punched parts of the predetermined shape. The punched parts cut into the predetermined shape will be discharged from the discharge hole 321 of the discharge plate 320 and transported to the storage channel. The storage channel can neatly store the punched parts produced by multiple punching processes, which is convenient for subsequent transportation and does not require manual sorting and stacking of the punched parts, thereby reducing labor costs and improving production efficiency.

[0130] Optionally, in one embodiment, the discharge component 400 includes a bottom support member 410 installed on the side of the discharge plate 320 away from the punching channel, and a pair of support members 420, and the bottom support member 410 and the pair of support members 420 are arranged to form a storage channel.

[0131] The bottom support member 410 is located at the lower end of the corresponding discharge hole 321 in the vertical direction, and a side of the bottom support member 410 close to the discharge hole 321 forms a support groove 411 adapted to the lower end of the discharge hole 321 .

[0132] A pair of support members 420 are respectively located on both sides of the discharge hole 321 in the horizontal direction, are higher than the bottom support member 410 in the vertical direction, and, when viewed from the side of the discharge plate 320 away from the punching die 310 in the horizontal direction, a side wall surface of each support member 420 close to the discharge hole 321 is aligned with the edge corresponding to the discharge hole 321.

[0133] The blanks pass through the discharge plate 320 from the discharge hole 321 and enter the discharge component 400 in sequence along the thickness direction. The lower end of each blank is supported on the supporting groove 411 of the bottom support 410, and the edges on both sides are respectively abutted against the corresponding support members 420.

[0134] This discharge component 400 forms at least three supporting points on the outer circumference of the blank through the bottom support member 410 and a pair of support members 420, and the contact points between the pair of support members 420 and the blank are higher than the contact points between the bottom support member 410 and the blank in the vertical direction, which can reduce the risk of the blank tipping over and ensure the placement stability of the blank.

[0135] Furthermore, the blanks formed after multiple cuts are stacked in sequence in the thickness direction in the discharge component 400. After a predetermined number of blanks are stacked in the discharge component 400, the entire stack of blanks are transported to the subsequent workstation manually or by other transfer structures. Compared with manually stacking and storing the materials, this discharge component 400 greatly improves production efficiency.

[0136] Optionally, in one embodiment, each support member 420 is configured as a plate-like structure, and a wall surface of one side of the support member 420 close to the discharge hole 321 is provided with multiple rows of brushes 421 arranged at equal intervals in the vertical direction.

[0137] When viewed from the side of the discharge plate 320 away from the punching die 310 in the horizontal direction, the free ends of each row of brushes 421 extend into the edge contour of the discharge hole 321 .

[0138] When the blank enters the discharge component 400 from the discharge hole 321, the bottom end of the blank is lifted on the supporting groove 411 of the bottom support 410, and the edges of the blank on both sides will squeeze the brushes 421 on the corresponding support members 420, so that the free ends of the brushes 421 are elastically deformed. Specifically, the brushes 421 of a pair of support members 420 located on the side of the blank close to the discharge plate 320 will be squeezed and bent in the direction close to the discharge plate 320; the part located on the side away from the discharge plate 320 will be squeezed and bent in the direction away from the discharge plate 320. The restoring force of the brush 421 reacts on the four corners of the blank, which can prevent the blank from tipping over, so that the blank is lifted upright on the bottom support 410.

[0139] Furthermore, when the edge of the blanking piece contacts the brush 421 , burrs formed by cutting the edge of the blanking piece will be cleaned by the brush 421 .

[0140] It should be noted that the number of discharge components 400 is not limited to one. The number of discharge components 400 corresponds one-to-one to the number of discharge holes 321 on the discharge plate 320. When multiple discharge holes 321 are provided on the discharge plate 320, a corresponding number of discharge components 400 are provided on the side of the discharge plate 320 away from the punching die 310.

[0141] Optionally, in one embodiment, two discharge holes 321 are arranged on the discharge plate 320 in the vertical direction, and a discharge component 400 is arranged at the corresponding position of each discharge hole 321. When viewed in the horizontal direction, in two adjacent discharge components 400 in the same row, the support members 420 close to each other are arranged at intervals, and two adjacent bottom support members 410 among the multiple bottom support members 410 are connected to each other, and the multiple bottom support members 410 are formed in one piece.

[0142] The specific structure of the support member 420 is not limited to the structure in the above-mentioned embodiment. In another alternative embodiment, an elastic layer is provided on one side wall of the support member 420, such as an elastic surface layer paved with rubber or sponge. When the blank enters the discharge component 400 from the discharge hole 321, the bottom end of the blank is supported on the support groove 411 of the bottom support member 410, and the edges of the blank on both sides will squeeze the corresponding elastic layer, the elastic layer will be squeezed to form a depression, and the elastic restoring force of the elastic layer will react on the blank, thereby preventing the blank from tipping over.

[0143] In summary, an embodiment of the present invention provides a punching device 10, which will be described below in conjunction with a specific working process.

[0144] Before the sheet material from the outside enters the material guide channel, it first passes through the sheet material tensioning roller 250 and a pair of sheet material limiting components 240 to enter the first material guide section 211 of the material guide plate 210, and is held on the upper wall of the material guide plate 210 by the pressing roller 231 arranged in the first material guide section 211, and then moves to the second material guide section 213 through the transition section 212, and is limited by the sheet material limiting component 240 of the second material guide section 213, and then is output from the downstream end of the material guide channel and driven by the traction roller group, passes through the guide plate 350 and enters the punching channel. At this time, the power of the punching drive member 331 is decelerated and torque-increased by the reducer 3328, and is transmitted to the driving wheel shaft 3323, and the driving wheel shaft 3323 rotates and is sleeved on the driving wheel shaft 3 The driving sprocket 3324 on 323 transmits power to the tensioning sprocket 3327 and the driven sprocket 3326 through a transmission chain. The driven sprocket 3326 drives the driven wheel shaft 3325 to rotate. When the driven wheel shaft rotates, the eccentric connecting arm 3329 swings, and pushes the mounting seat 333 and the blanking die 310 set on the mounting seat 333 to move toward the sheet in the blanking channel along the extension direction of the multiple guide rods 341, so as to cut part of the sheet into blanking parts of predetermined shapes. The blanking parts will be discharged from the discharge hole 321 of the discharge plate 320 into the storage channel of the discharge component 400; the rest of the sheet will be discharged from the lower end of the blanking channel and will be discharged after passing through at least two waste tensioning rollers 360 in sequence.

[0145] In the subsequent production process, the sheet material is continuously transported along the feeding direction driven by the traction roller group and is cut in turn by the punching component 300 in the punching channel. The punched pieces formed by multiple cuttings are stacked in the storage channel of the discharge component 400.
