DETAILED DESCRIPTION

[0042] In order to better understand and implement, the technical solutions in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model.

[0043] In the description of the utility model, it needs to be explained that the directions or position relations indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like are the directions or position relations shown based on the drawings, and are only for the convenience of describing the utility model and simplifying the description, and are not intended to indicate or imply that the devices or elements indicated must have a particular direction, be constructed and operated in a particular direction, and therefore cannot be understood as a limitation on the utility model.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terms used in the specification of the utility model herein are only for the purpose of describing the specific embodiments and are not intended to limit the utility model.

[0045] Specifically, please combine Figure 1 and Figure 2The utility model discloses a paperboard cutting device, including drive component 1, linear transmission mechanism 2, knife bar component 3 and casing component 4, drive component 1 is drive motor here, wherein, casing component 4 includes casing lateral wall 43, casing top wall 44 and the casing bottom wall for abutting support surface, the support surface here includes but is not limited to ground, desktop, mesa and the base surface of machining, casing top wall 44 and casing bottom wall are opposite and set up, and casing lateral wall 43 is located between casing top wall 44 and casing bottom wall, and casing lateral wall 43 extends along the circumferential side direction of casing bottom wall, and casing top wall 44, casing bottom wall and casing lateral wall 43 are cooperatively shaped into the casing inner chamber 41 of casing component 4, and knife bar component 3, drive component 1 and linear transmission mechanism 2 are all installed in casing inner chamber 41, then the paperboard cutting device in the process of operation, the operator especially children will not contact knife bar component 3, drive component 1 and linear transmission mechanism 2, guarantee the use safety and the comfort of operator and children.

[0046] Understandably, the paperboard cutting device is not limited to be applied to soft paperboard or hard paperboard, for example can also be used for cutting tin paper or aluminum film etc. Casing component 4 can be selected as hard transparent non-metal material (such as glass, acrylic etc.), to facilitate the observation and study of internal components by children, and can also be selected as metal material.

[0047] In the embodiment, specifically please combine Figure 1 、 Figure 2 、 Figure 4 And Figure 5 It is shown that drive component 1 is drivingly connected to the input portion of linear transmission mechanism 2, and knife bar component 3 is fixedly installed on the execution portion of linear transmission mechanism 2, then drive component 1 provides rotational torque to the input portion of linear transmission mechanism 2, then linear transmission mechanism 2 converts the rotational torque provided by drive component 1 into linear motion and transmits it to knife bar component 3, so that knife bar component 3 can make reciprocating linear motion.

[0048] Further, specifically please combine Figure 1 、 Figure 3 And Figure 6 It is shown that the outer top surface of casing top wall 44 is configured as a cutting station surface 42 on casing component 4, to facilitate children to place and push paperboard. A protective component 5 is provided on casing component 4 at the cutting station surface 42, and a station space 6 is provided between the cutting station surface 42 and the protective component 5, knife bar component 3 is provided in the protective component 5, and the cutting edge end of knife bar component 3 can protrude out of the protective component 5 and extend into the station space 6 under the driving of linear transmission mechanism 2, to provide paperboard blanking processing, and reset to retract into the interior of the protective component 5, to avoid the fingers of the operator from being cut by the cutting edge end of knife bar component 3 after penetrating into the station space 6, to ensure and improve the use safety of the paperboard cutting device.

[0049] It can be understood that the specific Figure 3 and Figure 6 It is shown that the distance between the cutting station surface 42 and the protection component 5 in the direction of the central axis of the cutter bar component 3 is the cutting thickness H of the station space 6, and the size of the cutting thickness H ranges between 1.5 mm and 3 mm.

[0050] When the cutting thickness H is less than 1.5 mm, the cutting thickness H is too small, which is not convenient for the paperboard to be quickly transferred into the station space 6 for punching, and the cutting thickness H is too small, which causes the paperboard to rub between the paperboard and the cutting station surface 42 and between the paperboard and the protection component 5 when the paperboard is transferred into the station space 6, which easily causes the surface of the paperboard to wrinkle, affecting the cutting effect of the paperboard. When the cutting thickness H is greater than 3 mm, the cutting thickness H is relatively large, which not only easily causes the risk of the fingertips of children being inserted into the station space 6 and being cut by the blade end of the cutter bar component 3, but also causes the risk of the thicker board being mistakenly transferred into the station space 6 by the children, thereby damaging the paperboard cutting device.

[0051] The size of the cutting thickness H of the station space 6 ranges between 1.5 mm and 3 mm, which not only effectively ensures the relatively good safety performance of the paperboard cutting device during use, but also ensures the stability of the paperboard cutting device during punching and cutting of the paperboard, thereby improving the service life of the paperboard cutting device. Preferably, the size of the cutting thickness H is 2 mm, 2.2 mm, or 2.5 mm.

[0052] As a preferred mode of the present embodiment, it is specifically shown in Figure 2 , Figure 3 , Figure 5 and Figure 6 The above-mentioned protection component 5 includes a protection seat body 51 and a protection cover body 52 arranged outside the cabinet component 4, and the protection cover body 52 can be selected from hard plastic or metal material. The material of the protection seat body 51 is preferably high-strength wear-resistant metal to ensure the service life. The protection cover body 52 is connected to the protection seat body 51, and the protection seat body 51 is fixedly connected to the cabinet component 4. Specifically, the cabinet top wall 44 of the cabinet component 4 is provided with a seat assembly opening, the shape and size of the seat assembly opening are matched with the shape and size of the protection seat body 51, the protection seat body 51 is embedded in the seat assembly opening, and the protection seat body 51 can be connected to the cabinet top wall 44 by using fasteners (such as bolts, nuts, and screws). For example, the protection seat body 51 is close to the cutting station surface 42, and the protection seat body 51 can also be welded to the cabinet top wall 44. Considering that the paperboard can be stably and smoothly transferred into the station space 6, the plane of the side of the protection seat body 51 close to the cutting station surface 42 is preferably flush with the cutting station surface 42.

[0053] Further, it is specifically shown in Figure 2 ,Figure 5 and Figure 6 As shown in Figs. 5 and 6, the protective seat body 51 is provided with a cutter bar through hole, the hole diameter of the cutter bar through hole is preferably matched with the diameter of the cutter bar component 3, or, within the assembly tolerance range, the hole diameter of the cutter bar through hole is larger than the diameter of the cutter bar component 3, then the cutter bar component 3 can be arranged in the protective seat body 51 and can do reciprocating linear motion. It can be understood that the inner hole wall of the cutter bar through hole and the surface of the cutter bar component 3 are matched in size and are smooth processed to ensure the accuracy and stability of the cutting process. The protective cover body 52 and the cutting station surface 42 are arranged to form a station space 6, then the cutter bar component 3 passes through the cutter bar through hole and can extend into the station space 6 to cut the paperboard in the station space 6.

[0054] As a preferred mode of the present embodiment, please refer to Figs. 5 and 6 Figure 5 and Figure 6 As shown in Figs. 5 and 6, the protective component 5 further comprises a protective connecting body 53, the protective connecting body 53 is arranged on one side of the cutter bar component 3, and the protective cover body 52 is connected with the protective seat body 51 through the protective connecting body 53. Specifically, the protective connecting body 53 comprises a support sleeve arranged between the protective cover body 52 and the protective seat body 51 and a connecting fastener, which can be a bolt, a screw or a stud. During installation, the connecting fastener is sequentially threaded through the support sleeve of the protective cover body 52 and the protective connecting body 53 and is threadedly connected to the protective seat body 51, so as to achieve the purpose of connecting the protective cover body 52 with the protective seat body 51 through the protective connecting body 53.

[0055] It can be understood that the protective cover body 52 is integrally formed with the support sleeve, for example, by injection molding, so as to facilitate the disassembly of the paperboard cutting device. Of course, the support sleeve of the protective connecting body 53 can also be an independent part, so that the cutting thickness H between the cutting station surface 42 and the protective component 5 can be changed by replacing the support sleeve, thereby achieving the purpose of efficiently and easily adjusting the cutting thickness H of the station space 6.

[0056] In some embodiments, the side surface of the cutter bar component 3 close to the station space 6 is provided as a cutter bar blade surface, and the circumferential side edge of the cutter bar blade surface is configured as the blade end of the cutter bar component 3, that is, the cutter bar component 3 is a blunt cutter bar. Not only is it convenient for processing and manufacturing the cutter bar component 3, but more importantly, it can avoid the risk of scratches to the operator (especially children) during the cutting process of the paperboard or during the disassembly process of the paperboard cutting device, thereby more effectively improving the safety performance of the paperboard cutting device.

[0057] In the process of cutting paperboard, the linear transmission mechanism 2 drives the knife bar component 3 to move along the central axis direction of the knife bar component 3 relative to the protective seat body 51 and extend into the working space 6, so that the knife bar surface of the knife bar component 3 is misaligned with the cutting working surface 42, thereby achieving the purpose of punching and cutting the paperboard.

[0058] For example, after the knife bar component 3 extends into the working space 6, the knife bar surface of the knife bar component 3 can abut and contact the protective cover body 52, thereby completing the punching and cutting of the paperboard. Of course, the inventor also discloses a preferred mode, that is, a knife position space is arranged on the protective cover body 52 along the central axis direction of the knife bar component 3. The knife position space can be a through hole structure, and can also be a groove structure. The diameter of the knife position space is preferably matched with the diameter of the knife bar component 3, or within the assembly tolerance range, the diameter of the knife position space can be larger than the diameter of the knife bar component 3. When the knife bar component 3 extends into the working space 6, the blade end of the knife bar component 3 is inserted into the knife position space.

[0059] On the one hand, the knife position space provides a buffer space for the knife bar component 3, avoiding the collision phenomenon when the knife bar component 3 directly abuts against the protective cover body 52, thereby avoiding damage to the protective cover body 52 by the knife bar component 3. On the other hand, during the process that the blade end of the knife bar component 3 extends into the knife position space, the blade end of the knife bar component 3 and the knife position space form relative sliding, that is, the knife position space can effectively guide the sliding of the blade end of the knife bar component 3, thereby reducing the vibration of the knife bar component 3 during punching and cutting, and improving the stability during punching and cutting of the paperboard.

[0060] As a preferred mode of the embodiment, the protective component 5 further comprises a protective shell sleeved outside the protective cover body 52. The protective shell can be made of transparent high-strength plastic. The protective shell is provided with a feeding conveying port communicating with the working space 6, so as to ensure that the paperboard can be conveyed into the working space 6 through the feeding conveying port for punching and cutting. It can be understood that the distance between the cutting working surface 42 and the protective component 5 along the central axis direction of the knife bar component 3 is greater than or equal to the width of the feeding conveying port. That is, through the constraint of the feeding conveying port of the protective shell, the following technical effects are achieved:

[0061] 1. The size of the paperboard that can pass through the feeding conveying port can be effectively limited, thereby avoiding that children mistakenly convey too thick paperboard into the working space 6 for forced processing, and improving the service life of the paperboard cutting device.

[0062] 2. The feeding port width is limited, and the distance between the feeding port and the cutter bar is appropriately increased, so as to better reduce or even eliminate the risk of children inserting their fingers into the working space 6, and further improve the safety of the paperboard cutting device.

[0063] 3. The assembly precision between the cutting working surface 42 and the protection component 5 and the machining precision of the protection component 5 are effectively reduced, so as to reduce the production requirements and assembly difficulty of the paperboard cutting device. In addition, the thickness of the paperboard that can enter the working space 6 for processing can be limited by replacing the protection shell, and the adjustment convenience and efficiency are further improved, so as to improve the experience of using the paperboard cutting device.

[0064] It should be noted that the linear transmission mechanism 2 includes a push rod member 21, which is an execution part of the linear transmission mechanism 2, and the cutter bar component 3 is fixedly connected to the push rod member 21. The push rod member 21 is drivingly connected to the driving end of the driving component 1, so that the driving end of the driving component 1 drives the push rod member 21 to move linearly and reciprocally, thereby driving the cutter bar component 3 to move linearly and reciprocally, achieving the purpose of punching and cutting paperboard.

[0065] In some embodiments, the driving end of the driving component 1 can be directly connected to the push rod member 21, and the push rod member 21 is driven to move linearly by the driving component 1. The driving component 1 can be a linear motor, or a pneumatic cylinder, or a hydraulic cylinder, or an electric cylinder, or other electrical elements capable of linear reciprocating motion.

[0066] As a preferred form of the present embodiment, please refer to the specific description of Figure 2 , Figure 4 and Figure 5 , the linear transmission mechanism 2 further includes a transmission assembly 22 and a guide assembly 23. The guide assembly 23 is guided to move in a direction consistent with the central axis direction of the cutter bar component 3. The push rod member 21 is slidingly connected to the guide assembly 23. The transmission assembly 22 is drivingly connected to the push rod member 21. The transmission assembly 22 is detachably connected to the driving end of the driving component 1. The guide assembly 23 is fixedly connected to the housing component 4.

[0067] In this way, the driving component 1 provides power and transmits it to the push rod member 21 through the transmission assembly 22, so as to drive the push rod member 21 to move linearly and reciprocally along the direction in which the guide assembly 23 is guided to move, thereby stably driving the cutter bar component 3 fixedly connected to the push rod member 21 to move linearly and reciprocally, achieving the purpose of punching and cutting paperboard.

[0068] Preferably, please refer to the specific description of Figure 2 and Figure 5As shown, the push rod member 21 has a transmission inner cavity 211, and the transmission assembly 22 is installed in the transmission inner cavity 211, so that the push rod member 21 covers at least a part of the transmission assembly 22, thereby effectively reducing the risk of the child touching the transmission assembly 22 during the assembly of the paperboard cutting device and / or during the operation of the paperboard cutting device, and achieving the purpose of double protection in cooperation with the cabinet part 4.

[0069] In some embodiments, specifically according to Figure 2 As shown, the transmission assembly 22 is a cam member, which is an input part of the linear transmission mechanism 2, and the peripheral curved surface of the cam member abuts against a first inner cavity surface of the transmission inner cavity 211, which is a side surface of the transmission inner cavity 211 close to the cutter bar part 3. The cam member cooperates with the push rod member 21 to form a cam transmission mechanism, and the cam member is connected to the driving part 1. In this way, the cam transmission principle is used to push the driven push rod member 21 to move back and forth according to a predetermined rule by the rotary motion of the cam member, which not only has a simple and compact structure, but also can accurately achieve the required motion rule. As long as the profile curve of the cam is properly designed, the push rod can obtain various expected motion rules.

[0070] In other embodiments, the transmission assembly 22 includes a crank member and a connecting rod member. The crank member is an input part of the linear transmission mechanism 2, and the crank member is connected to the push rod member 21 through the connecting rod member. The crank member is connected to the driving part 1, i.e., one end of the crank member is fixedly connected to the driving end of the driving part 1, and the other end of the crank member is hingedly connected to one end of the connecting rod member, and the other end of the connecting rod member is hingedly connected to the push rod member 21. The crank member, the connecting rod member, and the push rod member 21 form a crank slider mechanism, which can also achieve the purpose of converting the rotary torque provided by the driving part 1 into the reciprocating linear motion of the push rod member 21.

[0071] In other embodiments, the transmission assembly 22 includes a rotating body member and a translating body member. The translating body member engages or engages with the rotating body member. The rotating body member is an input part of the linear transmission mechanism 2, the translating body member is connected to the push rod member 21, and the translating body member is connected to the driving part 1. For example, the rotating body member can be selected as a gear, and the translating body member corresponds to a rack that engages with the gear. Of course, the rotating body member can also be selected as a worm gear, and the translating body member corresponds to a worm that engages with the worm gear. The rotating body member and the translating body member cooperate to form a gear and rack transmission mechanism or a worm and gear transmission mechanism, which can also achieve the purpose of converting the rotary torque provided by the driving part 1 into the reciprocating linear motion of the push rod member 21, and the transmission assembly 22 has a large transmission ratio and a compact structure. At the same time, the transmission is stable and noiseless.

[0072] It should be further noted that the guiding assembly 23 comprises a first guiding member 231 and a second guiding member 232, the second guiding member 232 is provided with a guiding hole for inserting the first guiding member 231, the extending direction of the first guiding member 231 is consistent with the direction of the central axis of the cutter bar component 3, and the first guiding member 231 and the second guiding member 232 are slidingly connected. Among them, the first guiding member 231 is arranged on the push rod component 21, and the second guiding member 232 is arranged on the cabinet component 4, that is, the first guiding member 231 is configured as a sliding block, and the second guiding member 232 is configured as a fixed guide rod / slide rail slidingly connected with the sliding block. In addition, the first guiding member 231 can also be arranged on the cabinet component 4, and the second guiding member 232 is correspondingly arranged on the push rod component 21, that is, the first guiding member 231 is configured as a sliding guide rod, and the second guiding member 232 is configured as a fixed sliding seat. In this way, not only the translation of the push rod component 21 is more stable and smooth, but also the moving accuracy of the cutter bar component 3 is higher, effectively improving the processing accuracy of the paperboard cutting device.

[0073] It should be further noted that the stroke of the cutter bar component 3 extending in the direction of the translation of the work station space 6 is the cutter bar stroke of the cutter bar component 3, the size of the protective component 5 in the direction of the central axis of the cutter bar component 3 is the total length of the protective component 5 of the protective component 5, and the cutter bar stroke is less than the total length of the protective component 5 of the protective component 5. It can be understood that the cutter bar stroke is greater than or equal to the cutting thickness H of the work station space 6, so as to ensure that the cutter bar component 3 can fully and completely cut the paperboard.

[0074] In this way, for example, when the cutter station space is a through hole structure, the cutter bar stroke is less than the total length of the protective component 5 of the protective component 5, which can ensure that the cutter bar component 3 will not extend through the through hole and extend out of the through hole structure, avoid the risk that the blade end of the cutter bar component 3 will extend through the hole and injure children, and also prevent the hair or other objects of children from being wrapped into the through hole structure, thereby further improving the use safety of the paperboard cutting device. For example, when the cutter station space is a sunken groove structure, the problem that the blade end of the cutter bar component 3 abuts against the groove wall of the sunken groove structure to cause damage to the cutter bar component 3 and the protective component 5 can be avoided.

[0075] As a preferred mode of the present embodiment, please refer to Figure 2 and Figure 5As shown, the paperboard cutting device further comprises a coupling 7, which is preferably a torque limiting coupling 7, so that when overload or mechanical failure causes the required torque to exceed the set value, it limits the torque transmitted by the transmission system in the form of slip, and at the same time stops the driving part 1 with a signal output, and restores the connection automatically when the overload condition disappears. With the driving part 1, it can effectively ensure that the cutting device can only cut paperboards within a certain thickness range, such as 2mm, and cannot cut harder or thicker materials, thereby preventing children from putting materials with too high hardness into the driving part 1 and causing damage, and achieving the purpose of avoiding high-risk operation.

[0076] Here, the coupling 7 also enables detachable connection between the driving part 1 and the linear transmission mechanism 2, so that the driving part 1, the coupling 7 and the linear transmission mechanism 2 can be independently disassembled and replaced, which not only facilitates maintenance, but also facilitates subsequent upgrading and functional expansion.

[0077] Based on the structure and connection relationship of the above paperboard cutting device, the inventor also discloses a blanking system comprising the above paperboard cutting device, an overload protection device and a total control module, the overload protection device is used to monitor the operation state of the knife bar part 3, and the driving part 1 of the paperboard cutting device and the overload protection device are electrically connected to the total control module.

[0078] In this way, when a child mistakenly moves a paperboard with high hardness to the work station space 6 of the paperboard cutting device, causing the knife bar part 3 to be unable to process, the overload protection device will be able to monitor that the knife bar part 3 cannot move and / or the driving part 1 cannot rotate in time, and generate a monitoring signal to the total control module. The total control module receives the monitoring signal and sends a control instruction to the driving part 1 to control the driving part 1 to stop providing rotating torque (stop running), so as to ensure that the knife bar part 3 and the driving part 1 are not damaged, and the user can also be reminded through color-changing indicator lights and sound alarms, thereby further improving the service life and use safety of the paperboard cutting device and preventing potential safety hazards.

[0079] The technical means disclosed by the utility model scheme is not limited to the technical means disclosed by the above-mentioned embodiments, but also includes technical solutions composed of any combination of the above technical features. It should be noted that for ordinary skilled persons in the art, without departing from the principles of the utility model, a number of improvements and refinements can be made, and these improvements and refinements are also considered within the protection scope of the utility model.
