Description

Technical Field

[0001] This invention relates to the field of sheet metal cutting technology, and more specifically, to a child-safe cardboard die-cutting workstation. Background Technology

[0002] Currently, children's creative crafts and STEAM education (STEAM refers to science, technology, engineering, art, and mathematics) are developing rapidly. The demand for safe, visual, and easy-to-use cutting tools in families and schools is constantly increasing. On the one hand, traditional children's craft tools are mainly scissors and craft knives, which have problems such as high force, low precision, and easy hand injury, and are not suitable for creating thick cardboard, large-sized structures, or complex shapes. On the other hand, platform tools such as electric table saws, coping saws, and jigsaws for adults are relatively mature, but they generally use sharp blades that rotate at high speed or reciprocate, and their safety protection and interaction methods are not suitable for children.

[0003] Currently, most electric paper cutters for children are limited to simple straight-line cutting or thin paper cutting, which is insufficient to meet the actual needs of families and classrooms for large-area cardboard building and structural creation. In addition, existing electric paper cutters do not adequately consider the cleaning, collection, and safety of waste materials. For example, the applicant's earlier Chinese utility model patent application, application number 202422543626.9, discloses a cardboard cutting device and its punching system, which solves the problem that children cannot use existing cutting tools to cut thicker cardboard and effectively ensures the safety of children in the process of cutting cardboard by hand. However, it has certain limitations in the cleaning and collection of waste materials, and it is easy to get clogged when cutting adhesive paper, felt and other sticky and fibrous materials. There is still room for improvement in terms of safety.

[0004] Therefore, it is necessary to propose a child-safe cardboard die-cutting workstation to at least partially solve the problems existing in the prior art. Summary of the Invention

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0020] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0021] like Figure 1 As shown, the present invention provides a child-safe cardboard die-cutting workstation, comprising: The outer casing 1 has an operating platform 2 mounted on it; The punching and cutting assembly 3 includes a protective blade holder 4 and a punching blade bar 5. The protective blade holder 4 extends out of the operating platform 2 and forms a work station space 9 with the table surface of the operating platform 2. The punching blade bar 5 moves up and down reciprocally within the protective blade holder 4 to cut the material that enters the work station space 9. The drive assembly 6, which is located inside the housing 1, is connected to the punching cutter bar 5 for transmission. Waste collection component 7 is located below workstation space 9.

[0022] The top of the outer casing 1 and the operating platform 2 are both provided with through holes that allow the punching and cutting assembly 3 to pass through. The operating platform 2 is movably connected to the outer casing 1. The top of the outer casing 1 is provided with a groove corresponding to the operating platform 2, and the operating platform 2 can be limited and overlapped in the groove; thus making it easy to replace the operating platform 2.

[0023] A portion of the protective blade holder 4 is fixed inside the outer shell 1, while the other portion passes through the outer shell 1 and the operating platform 2, forming a workstation space 9 between the protective blade holder 4 and the operating platform 2. The height of the workstation space 9 is set to allow only materials of a set thickness to pass through, and its maximum height (e.g., 2mm~5mm) is less than the thickness that can accommodate a child's finger or other large, hard foreign objects, and greater than the thickness of the material after compression, which is set to a thickness of 0.5mm~5mm. The main applicable materials of this invention are soft or semi-soft boards such as cardboard, adhesive paper, and felt, and it can also be extended to other non-metallic lightweight sheets, such as EVA foam (EVA is ethylene-vinyl acetate copolymer), thin plastic sheets, thin cork sheets, and other low-hardness materials. The punching cutter bar 5 is driven by the drive assembly 6, and it can move up and down within the protective cutter holder 4. The side of the punching cutter bar 5 used for cutting materials is exposed in the work station space 9. Therefore, the punching cutter bar 5 can cut materials that enter the work station space 9. The cut waste can fall from the workstation space 9 and be collected by the waste collection component 7, thereby preventing waste from accumulating on the operating platform 2 and affecting the cutting.

[0024] Through the above design, the workstation space 9 can provide a safe space for material cutting, avoid the cutting part of the cutting blade 5 being exposed, ensure safety during cutting, and reduce the potential risk of injury to child users; the waste collection component 7 can collect the waste discharged downward from the workstation space 9, realize the unified collection of waste, avoid accumulation or scattering in the workstation space 9, make cleaning easier, and reduce the cleaning burden.

[0025] like Figure 2 and Figure 3 As shown, in one embodiment, the driving component 6 includes: The drive unit 61 is disposed inside the outer casing 1; The eccentric shaft 62 is connected to the output end of the drive body 61; The slider 63 moves up and down inside the outer casing 1 and has a transverse limiting groove 631. The end of the eccentric shaft 62 away from the driving body 61 is limited and set in the transverse limiting groove 631. The slider 63 is connected to the punching cutter bar 5.

[0026] The slider 63 slides up and down within the limiting frame 10 inside the housing 1. The outer side of the eccentric shaft 62 is provided with a bearing 64, which is fixedly connected to one side of the limiting frame 10. The protective knife holder 4 is fixed on the limiting frame 10, and its top passes through the limiting frame 10, the housing 1, and the operating platform 2 in sequence.

[0027] The drive body 61 can be any type of motor in the prior art, which can be fixed in the housing 1 by the frame; the eccentric shaft 62 is coaxially connected to the output end of the drive body 61, and the end of the eccentric shaft 62 away from the drive body 61 is provided with a drive shaft body that is eccentrically set with the drive body 61, and the drive shaft body slides in the transverse limiting groove 631 of the slider 63; During the blanking process, the drive body 61 operates, causing the eccentric shaft 62 to rotate. Since the drive shaft is eccentrically set with the drive body 61, the drive shaft rotates in a circular motion around the axis of the drive body 61, thereby driving the slider 63, which is slidably connected to the drive shaft, to move. Since the slider 63 is restricted by the limit frame 10, the slider 63 can only move up and down, thereby driving the blanking cutter bar 5, which is fixedly connected to the slider 63, to move up and down.

[0028] In addition, a control module for controlling the operation of the drive body 61 can be selectively set. Through pulse width modulation (PWM) speed regulation or multi-speed selection control mode, a suitable punching frequency can be provided for different materials and working modes. The punching frequency is the frequency of the up-and-down reciprocating motion of the punching cutter bar 5.

[0029] like Figure 4 and Figure 5 As shown, in one embodiment, the protective blade holder 4 includes: The knife holder body 41 is located inside the outer casing 1, and its interior is provided with a limiting shaft hole 412 for the up and down movement of the punching and cutting knife bar 5; The protective part 42, which is connected to the tool holder body 41, is located above the table surface of the operating platform 2. The limiting shaft hole 412 extends upward into the protective part 42, and a work station space 9 is formed between the protective part 42 and the table surface of the operating platform 2. The blanking section 51 is located at the position corresponding to the work station space 9, and a chip removal gap 8 is formed between the blanking section 51 and the limiting shaft hole 412. The tool holder body 41 is provided with a chip removal channel 411 that communicates with the chip removal gap 8, and the chip removal channel 411 is located below the chip removal gap 8.

[0030] The chip removal channel 411 is inclined downward on the side away from the axis of the cutter body 41; at least two chip removal channels 411 are provided to ensure chip removal efficiency and further avoid clogging when cutting adhesive paper, felt and other sticky and fibrous materials. Furthermore, such as Figure 3As shown, the top of the limiting frame 10 inside the outer shell 1 is provided with a mounting hole, the tool holder body 41 is provided with a stepped surface, and the tool holder body 41 is provided with an external thread on the outer side above the stepped surface. The part of the tool holder body 41 located below the stepped surface is inside the limiting frame 10, and the part located above the stepped surface passes through the top of the limiting frame 10. The tool holder body 41 is locked and fixed to the limiting frame 10 by means of a nut and an external thread connection.

[0031] like Figure 5 As shown, the limiting shaft hole 412 is provided through the knife holder body 41 and the protective part 42. When the punching knife bar 5 moves up and down reciprocatingly, its top will not pass through the protective part 42, thus ensuring safety. The blanking section 51 is located at the position corresponding to the workstation space 9. A blanking opening is formed on one side of the blanking section 51, creating a chip removal gap 8 between the blanking section 51 and the limiting shaft hole 412. The chip removal gap 8 is connected to the chip removal channel 411. During blanking, the blanking section 5 moves downwards to perform a biting cut on the material (e.g., cardboard). Figure 5 As shown, the waste material from the punching process can fall from the chip removal gap 8 into the chip removal channel 411 under the downward movement of the punching cutter bar 5, and then be guided along the chip removal channel 411 into the waste material collection assembly 7, thereby preventing the waste material from accumulating at the workstation space 9 and affecting the punching and cutting.

[0032] like Figure 4 As shown, the bottom surface of the outer casing 1 is provided with an upwardly recessed receiving groove 16, and the protective part 42 of one punching workstation can be inserted into the receiving groove 16 of another punching workstation, which facilitates the stacking and storage of multiple punching workstations.

[0033] like Figure 4 and Figure 6 As shown, in one embodiment, the waste collection assembly 7 includes: The chip removal guide groove 71 is installed inside the outer casing 1 and is inclined. The tool holder body 41 is installed through the chip removal guide groove 71 and the chip removal channel 411 is located above the chip removal guide groove 71. Waste bin 72 is located below the discharge end of chip discharge guide trough 71. The outer shell 1 is provided with a mounting groove 11 for accommodating waste bin 72. Waste bin 72 is detachably connected to the mounting groove 11.

[0034] Furthermore, the waste bin 72 can be a pull-out type, which can be completely pulled out from the mounting slot 11 under the action of external force, so as to facilitate the cleaning of the waste collected in the waste bin 72.

[0035] like Figure 4As shown, the chip discharge guide trough 71 is connected to the top of the outer shell 1, and the tool holder body 41 is installed through the chip discharge guide trough 71. Waste chips are guided from the chip discharge channel 411 into the chip discharge guide trough 71, and then slide down the inclined surface of the chip discharge guide trough 71 into the waste bin 72 for collection.

[0036] In one embodiment, to ensure user safety, a safety detection and protection module may be selectively provided, which includes: a safety detection unit and a waste detection unit for detecting the waste bin 72, an overload protection unit for detecting the punch cutter bar 5, and a time monitoring unit for detecting the drive assembly 6; the safety detection unit, waste detection unit, overload protection unit, time monitoring unit, and drive assembly 6 are all communicatively connected to the control board 13 disposed in the housing 1.

[0037] Furthermore, the safety detection unit and waste detection unit for detecting waste bin 72 are as follows: A safety detection unit is used to detect the open and closed states of the waste bin 72; The waste detection unit is used to detect whether the waste bin 72 is full of waste.

[0038] The safety detection unit can be any existing technology capable of detecting the opening of the waste bin 72 (e.g., ...). Figure 7 The waste bin 72 shown is pulled out from the mounting slot 11) and closed (as shown). Figure 8 The device that allows the waste bin 72 to be fully pushed back into the mounting slot 11 is preferably a proximity switch (e.g., a Hall effect proximity switch), which is disposed in the mounting slot 11, and the waste bin 72 is provided with a trigger block corresponding to the proximity switch; Specifically, the trigger block uses a magnetic sheet, which is set on the outer wall of the waste bin 72 near the drive assembly 6. The proximity switch is set in the mounting slot 11 near the side wall of the drive assembly 6. When the waste bin 72 is closed correctly, the proximity switch remains closed when the magnetic sheet approaches it (the principle is that the internal circuit state of the proximity switch changes, thereby identifying the presence of a magnetic object nearby). When the waste bin 72 is opened, the proximity switch changes state, i.e., it is in the open state. Thus, the opening and closing of the waste bin 72 can be detected based on the closed and open states of the proximity switch. For example, the closed and open signals of the proximity switch are input to the control board 13. If the control board 13 receives a closed signal, it indicates that the waste bin 72 is completely closed, and the drive assembly 6 can be controlled to run. If the control board 13 receives an open signal, it indicates that the waste bin 72 is not closed. At this time, the user can be reminded, and the drive assembly 6 can be controlled to stop running. The waste detection unit can be any device in the prior art that can detect the height of waste accumulation in the waste bin 72. It is preferably an ultrasonic sensor, which is set at the top of the mounting groove 11 to emit ultrasonic waves downwards and receive the returned ultrasonic waves. An ultrasonic sensor mounted on the top of the mounting slot 11 emits ultrasonic waves downwards. When the ultrasonic waves encounter the accumulated waste, they return and are received by the ultrasonic sensor. By measuring the return time of the ultrasonic waves and the known wave speed, the distance between the ultrasonic sensor and the accumulated waste can be obtained. The distance can be used to determine whether the height of the accumulated waste has reached the preset height. If the preset height has been reached, it indicates that the waste bin 72 is full. After receiving the signal detected by the ultrasonic sensor, the control board 13 controls the drive component 6 to stop running and reminds the user to clean the waste bin 72.

[0039] Furthermore, the overload protection unit that detects the punch cutter bar 5 is as follows: An overload protection unit, installed on the drive assembly 6, is used to detect load changes in the punching cutter bar 5.

[0040] The overload protection unit is a pressure sensor installed on the bottom surface of the transverse limiting groove 631. Any pressure sensor that can be installed on the bottom surface of the transverse limiting groove 631 can be used, preferably a thin-film pressure sensor. The sensor covers the bottom surface of the transverse limiting groove 631. When the eccentric shaft 62 rotates and drives the slider 63 to move downward, the drive shaft of the eccentric shaft 62 will exert a force on the bottom surface of the transverse limiting groove 631. The pressure sensor will detect the pressure and input the detected pressure signal to the control board 13. After receiving the pressure signal, the control board 13 will make a judgment. For example, if the punching bar 5 encounters a load that exceeds the design range (such as encountering a hard object or an excessively thick material), the pressure detected by the pressure sensor will exceed the set pressure value. The control board 13 will then control the drive assembly 6 to rotate in the opposite direction so that the punching bar 5 moves upward to relieve the force and form overload protection. Alternatively, the overload protection unit is a torque limiting coupling connected between the eccentric shaft 62 and the drive body 61. When the punching bar 5 is cutting and encounters a load that exceeds the design range (such as when encountering a hard object or an excessively thick material), the torque transmitted by the torque limiting coupling will exceed the set value. The torque limiting coupling will disengage or slip, causing the eccentric shaft 62 and the drive body 61 to separate, thereby forming protection.

[0041] Furthermore, the time monitoring unit for detecting the drive component 6 is as follows: The time monitoring unit is electrically connected to the drive component 6 and is used to detect the standby time of the drive component 6; when the standby time of the drive component 6 exceeds the set time, it will automatically shut down.

[0042] The time monitoring unit can be implemented by a timer integrated on the control board 13. The control board 13 detects the operation signal of the drive component 6 to start or reset the standby timer. After the standby timer is started, if the standby time exceeds the set time, the device will automatically shut down to prevent children from forgetting to turn it off.

[0043] The security detection and protection module also includes a platform detection unit for detecting the operating platform 2, as detailed below: The platform detection unit is communicatively connected to the control board 13. The platform detection unit is located on the bottom surface of a groove on the top of the housing 1. It can employ any existing device capable of detecting whether the operating platform 2 is placed in the groove, such as a pressure sensor or microswitch similar to those used in the transverse limiting groove 631. When a pressure sensor is used, the operating platform 2 exerts a force on the pressure sensor when placed in the groove, detecting the pressure. When the operating platform 2 is not placed in the groove, the pressure sensor does not detect pressure, and the detected pressure signal is input to the control board 13 to control the operation of the drive assembly 6, thus ensuring safety. When a microswitch is used, the operating platform 2 is placed in the groove and presses down on the plunger of the microswitch, causing its internal contacts to actuate (e.g., changing from a normally open state to a closed state). The signal corresponding to the closed or normally open state is input to the control board 13, which then controls the operation of the drive assembly 6. In other words, when the operating platform 2 is not placed in the groove, the drive assembly 6 does not operate, ensuring safety.

[0044] Furthermore, it also includes: The indicator light 12, which is set on the housing 1, is electrically connected to the safety detection unit, waste detection unit, overload protection unit and time monitoring unit through the control board 13.

[0045] The control board 13 is located inside the housing 1. The outer side of the housing 1 is provided with indicator lights 12 and buttons, including a power switch 14 and a speed adjustment key 15 that are electrically connected to the drive assembly 6. like Figure 7 As shown, the power switch 14 is located on the front side of the housing 1, and the indicator light 12 is ring-shaped and located on the outside of the power switch 14; when in use, it is convenient for the user to operate the power switch 14 and at the same time to observe the color change of the indicator light 12. The speed adjustment key 15 is located on the side of the housing 1 and is used to adjust the rotation speed of the drive body 61 in order to adjust the punching frequency of the punching cutter bar 5.

[0046] The indicator light 12 can be set as a ring-shaped three-color indicator light 12, or three ring-shaped three-color indicator lights 12. One indicator light 12 corresponds to the safety detection unit and the waste detection unit, and the other two indicator lights 12 correspond to the overload protection unit and the time monitoring unit, respectively.

[0047] Specifically, indicator light 12 can perform the following operations: When the punching and cutting assembly 3, the waste bin 72 and the drive assembly 6 are all in normal operating condition, the indicator light 12 will light up white. When the safety detection unit detects that the waste bin 72 is open or that the waste inside is full, or when the overload protection unit detects that the load on the punching bar 5 is overloaded, the indicator light 12 will light up red. When the time monitoring unit detects that the standby time of the drive component 6 exceeds the set time and automatically shuts down, the indicator light turns yellow.

[0048] For the control board 13, any existing circuit board or device that can realize the communication connection of the safety detection unit, waste detection unit, overload protection unit, time monitoring unit, drive component 6, indicator light 12 and button 14 and realize the corresponding functions can be adopted, such as microcontroller (MCU), such as STM32F103 series or GD32 series devices.
