Description

Axial-variable USB comprehensive electric cutter tool for rapidly cutting foam

Technical Field

The invention relates to the technical field of foam cutting, in particular to a variable axial USB comprehensive electric cutter tool for rapidly cutting foam, which is suitable for artist operators, school students, housewives, artists and foam cutting factories.

Background

In the field of material technology, the material can be analyzed and applied according to different material characteristics, for example, foam, plastic, sponge and the like are common materials in production and processing, and can always take on a certain shape, which is also an advantage to be utilized. However, when cutting, the foam can bear some pressure without large deformation, but if the surface formed by processing with a knife, a saw and the like is often not smooth and flat enough, if the surface cannot be cut by a shearing knife, only small planes can be cut by a particularly sharp blade, and a slightly larger plane and a curved blade cannot be used. For another example, the sponge is deformed by slightly pressing, and tools such as a knife and a scissors inevitably apply pressure to the material, and if the material is deformed, the amount of the material to be cut is difficult to grasp, so that the sponge is difficult to obtain a good work by the knife and the scissors.

According to incomplete statistics, the conventional main current cutting technology of foam, sponge and the like by the person skilled in the art still adopts a manner of using a utility knife, a dry battery to connect with a heating wire and the like, but the related situation is discussed above, and the adopted tools have a plurality of fatal defects when in use, and the foam is foamed to form a rather soft tissue, so that the expected shape is difficult to cut when in cutting, which is known from practical application:

when the cutter is used for cutting, the cutter is likely to cut into seven or eight parts, the edge is very uneven, and the serious problem is that foam scraps accompanied with cutting can scatter on the ground along with the friction of the cutter, pollute the environment and are more unfavorable for human health;

when cutting, if a dry battery is used to connect the heating wire, a user needs to grasp a large arc-shaped holding part and shuttle the arc-shaped holding part back and forth in the foam, and although the edge is more neat for the craft knife, the tool for connecting the heating wire by using the dry battery is not easy to hold by one hand or two hands, especially for the minor adults with smaller palms, students or women, the labor is more laborious, and in addition, the foam to be cut sometimes has a shape with a solid geometry or a wider meat thickness, the angle is limited, and the operation is difficult.

Although these conventional tools are not practically suitable, foam, plastic and sponge have a common characteristic that they are easily melted by heat and are poor conductors of heat, and it is tried to be easy to implement if a high Wen Tiesi piece is used for cutting, and the shape of other parts is not affected if the speed is well known just like a knife cutting bean curd, so that the use of thermal cutting method for processing foam, plastic and sponge is a more ideal method.

The technical solution of the electric cutting knife is designed according to the principle of hot cutting by a person skilled in the art, but even if the person can implement according to the technical teaching of this hot cutting method, after excessive cost development, only the smooth cutting end face can be ensured and the generation of scraps can be reduced, forming a series of tools for hot cutting foam, however, the intended setting purpose is still difficult to achieve, because a number of unexpected problems are also accompanied.

These problems occur under the condition that the different requirements of users cannot be met: because these foam electric heat cutters all adopt fixed straight handle, grip the direction fixed, different sexes, different age groups etc. use the palm size of crowd, grip the degree size of strength different, the user that the palm area is less can obviously feel very hard when gripping this kind of straight handle electric cutter and cut the foam, once take off the hand, easily injure oneself, even if can avoid this potential safety hazard, still have fundamental defect when the user cuts the foam, can't operate the cutter and cut the foam of arbitrary shape according to different actual operation demands.

In summary, the present invention is based on the prior art, and combines with the verification of practical application to discuss how to solve the fatal defects of the above analysis in one technical solution at a time, and provides a technical solution for further developing and designing the product structure in the technical field, and is also beneficial to solving a plurality of technical problems in the same technical field and improving the expansibility of the technical solution.

Detailed Description

Example 1

As shown in fig. 1, fig. 1-2, fig. 1-3, fig. 1-4, fig. 1-5, and fig. 1-6, the technical means implemented by the variable axial USB integrated electric cutter tool for rapidly cutting foam according to the first embodiment of the present invention is to achieve the purpose of enabling various groups of people to operate cutting tools with different cutter heads and cut foam bodies with arbitrary shapes in a manner of forming a certain angle with the objects to be cut through hand-held tools on the basis of ensuring smooth and chipless cutting end surfaces, thereby flexibly, time-saving, labor-saving and zero-error. Therefore, in order to embody the most basic humanized design, the technical scheme of the invention firstly comprises a handle body 10, the outer surface of the handle body 10 is used for basic handheld functions and is matched with corresponding anti-skid patterns and the like, and the tail end of the handle body is connected with a wiring for connecting to an external USB interface, so that the USB interface is used for taking electricity, and the USB interface of all computers, or an android mobile phone charger or a USB (5 VDC) interface on a charger, namely the USB interface can be used for taking electricity (further comprising a notebook computer, a tablet computer, a mobile power supply, a smart mobile phone charger and the like), so that better portability is formed and the USB interface can be used for connecting to a power supply. From the most basic design, it can be seen that the integrated electric cutter tool implemented by the invention is not completely used for producing and cutting materials such as foam in a general factory, but the mode of cutting the foam by a factory technician is changed by the tool, and the tool is applicable to the use except for cutting the foam by a general non-technician; accordingly, the handle body 10 may also be provided with LED indicator lights for display purposes as other electronic or electric products, and a corresponding switch assembly may be provided on the handle body 10.

Further analysis of the handle body 10 structure set forth above:

when the person skilled in the art designs, the handle body 10 is not directly in a one-section round, square or other shape, but the front end part of the handle body is provided with a handle rotating part 5, and the handle body 10 can relatively rotate at a certain angle, so that various different user groups can hold the handle by hand

The handle body 10 is provided with a hollow rotating shaft part 9, the rotating shaft part 9 is obliquely arranged, and referring to fig. 1-4 and 1-5, the rotating shaft part 9 is formed by two cylinders, one cylinder is used for fixedly contacting the handle rotating part 5, the other bottom cylinder is used as a handle fixing part 92 for fixedly contacting the handle body 10, a limiting groove 91 is formed on the outer surface of the cylinder fixedly contacting the handle rotating part 5, the shaft connecting part 52 of the handle rotating part 5 is clamped in the limiting groove 91 and can rotate within a certain angle range in the limiting groove 91, for example, because the end surface of the connecting part of the handle body 10 and the handle rotating part 5 is of an elliptic structure, that is, the handle rotating part 5 rotates along the elliptic end surface of the handle body 10, the rotation direction is obviously not perpendicular to the length direction of the handle body 10, but the handle rotation part 5 can rotate by 45 degrees around the rotation shaft part 9 along the inclined rotation shaft part 9, in fact, the handle rotation part 5 after the rotation is in a vertical state with the handle body 10, so that the electric knife is further in an angle with the object to be cut, the electric knife is more convenient to operate, the electric knife can be directly used for facilitating the smooth holding of a user (such as a student or a woman) with smaller palm or insufficient grip, the assembled handle body 10 and the handle rotation part 5 can be seen from the figures 1-3, when the handle body 10 is assembled, the handle fixing part 92 of the rotation shaft part 9 is clamped on the groove position in the end face of the handle body 10, the shaft connecting part 52 of the handle rotating part 5 is clamped in the limit groove 91 of the rotating shaft part 9, and meanwhile, a shaft fixing piece 8 with an elliptical cross section is added between the connecting end surfaces of the handle body 10 and the handle rotating part 5 so as to improve the installation stability of the rotating shaft part 9;

according to the design of the rotating shaft part 9, a designer in the technical scheme firstly considers the technical scheme from the aspect that the main working end of the handle can be presented with a certain angle with a to-be-cut object, and for the technical field of foam cutting knives, no suggestion exists in the past that the designer can be reminded of the design in the technical field of foam cutting, and no intention of the design exists in any product in the past;

accordingly, due to the adoption of the design scheme that the handle is at a certain angle with the object to be cut, people with smaller palms or insufficient grip strength can directly benefit, the traditional straight pipe one-section structure enables some people to continuously operate, the grip strength is insufficient and the hand is ache in a short time, by the design of the link of the invention, a proper operation direction can be obtained by adopting the handle with two vertical sections, and a larger grip strength is not needed, for example, after rotation, the handle rotating part 5 vertical to the handle body 10 can easily perform cutting operation in a downward vertical state, or a certain angle can be formed between the handle rotating part 5 and the object to be cut according to needs, and no matter what cutting mode is, the cutting mode is obviously superior to the traditional straight pipe one-section cutting mode.

For the above-mentioned handle rotating portion 5, a critical first step is realized for achieving the purpose of flexibly cutting different shapes, and likewise, the technician continues to design the cutting bit portion to be adopted along the thought of this handle rotating portion 5, and obviously, the conventional structure cannot be adopted, and the specific embodiment is as follows:

as shown in fig. 1-6, the implemented connecting end of the knife part of the handle rotating part 5 is flexibly provided with a plurality of replaceable knife heads, in the first embodiment, a half-moon-shaped knife head is preferably adopted, a fixed end seat 4 is additionally arranged for fixing the knife head, the top of the fixed end seat 4 is provided with a corresponding fixing position for fixing the knife head, the fixed end seat 4, the handle rotating part 5 and the handle body 10 are respectively formed in the same way, the fixed end seat 4 is spliced by a left part and a right part, electrode guide holes are formed on the bottom surface of the end seat after the splicing, correspondingly, after the left part and the right part of the handle rotating part 5 fixedly combined with the fixed end seat 4 are spliced, another electrode guide hole is formed on the top of the handle rotating part 5, and the electrode guide hole position corresponds to the electrode guide hole position of the fixed end seat 4, so that the conductive electrode 31 of any knife head can be inserted into the handle rotating part 5 through the corresponding electrode guide hole;

correspondingly, the copper pipe 7 with the copper post 6 is arranged in the handle rotating part 5, the lower end of the copper pipe 7 is connected with corresponding wires, the wires penetrate through the hollow rotating shaft part 9 and enter the handle body 10, the technical scheme of the invention also considers the safety problem of the wires, and the handle rotating part 5 only makes 45-degree reciprocating displacement along the fixing direction of the rotating shaft part 9 instead of making a whole 360-degree arbitrary rotation when rotating, so the problem that the wires are twisted off is not involved in the whole rotating process, and one of the potential safety hazards is solved;

further, in order to realize "zero error operation of cutting tools with different tool bits and cutting foam bodies with arbitrary shapes", the bottom of the implemented fixed end seat 4 is additionally provided with a positioning pin 41, meanwhile, the part of the conductive electrode 31 penetrating into the handle rotating part 5 is additionally provided with a pair of positioning pin holes 51 (or at least one) for fixing and clamping the positioning pin 41, and the position of each positioning pin hole 51 is respectively located at the adjacent position of the corresponding electrode guide hole, thereby realizing the structure of preventing misplug of one positioning pin hole 51 beside each electrode guide hole, so that the conductive electrode 31 of the positive electrode and the conductive electrode 31 of the negative electrode cannot be reversely inserted, and the fixed end seat 4 and the handle rotating part 5 can be fixedly combined only when each positioning pin 41 of the fixed end seat 4 can be smoothly inserted into the corresponding correct positioning pin hole 51, and the specific embodiment is that: the size of the designed pin hole can be determined by the use requirement, for example, the width of the cross section is designed to be one large and one small for two positioning pins 41, and accordingly, the aperture of the positioning pin hole 51 configured by the handle rotating part 5 is also one large and one small correspondingly, so that the positioning pin 41 with the larger cross section can only be inserted into the positioning pin hole 51 with the larger aperture, even if the position is inserted incorrectly, the positioning pin 41 with the larger cross section cannot be inserted into the positioning pin hole 51 with the smaller aperture due to the restriction of the aperture, and thus, the positive and negative conductive electrodes 31 can be prevented from being inserted reversely in this way, on the basis of clamping the electric knife, the correct polarity of the power supply and the clamping of the electric knife can be ensured to the greatest extent, and the other potential safety hazard is solved.

From the above, it is known that when the two conductive electrodes 31 of the tool bit penetrate from the top to the bottom of the fixed end seat 4, the lower ends of the two conductive electrodes 31 extend to the lower side of the fixed end seat 4, and then are assembled together with the fixed end seat 4 on the handle rotating portion 5, because the fixed end seat 4 is fixed with the positioning pin 41 structure implemented by the above cooperation of the handle rotating portion 5, after the fixation, the lower ends of the two conductive electrodes 31 of the tool bit are inserted into the inner portion of the handle rotating portion 5 and contact with the corresponding copper column 6, thereby completing the installation of the tool bit, obviously, for the assembly of each tool bit, a fixed end seat 4 can be matched, the function of flexibly inserting and extracting the fixed end seat 4 on the handle rotating portion 5 is realized, and the disassembly and assembly of the corresponding tool bit are completed.

According to the variable axial USB comprehensive electric cutter tool for rapidly cutting foam, the adopted half-moon-shaped cutter head comprises the heating wire 1, the copper strips 2 and the stainless steel heat conduction frames 3, the two stainless steel heat conduction frames 3 are of arc structures, the lower ends of the two stainless steel heat conduction frames are respectively provided with the corresponding positive and negative electric conduction electrodes 31, the other end of each stainless steel heat conduction frame 3 is fixedly connected with the heating wire 1 through the copper strips 2, when the variable axial USB comprehensive electric cutter tool is used, a power switch outside the handle body 10 is stirred, any electric cutter arranged on the handle rotating part 5 can be rapidly heated for about ten seconds, the temperature for cutting foaming glue is reached, the electric cutters can be moved to cut according to a preset shape, meanwhile, when the power switch is stirred backwards to cut off, the selected heating electric cutters can be rapidly cooled, when the cutting operation is required, the repeated operation is performed, and the forming can be successfully completed.

The variable axial USB comprehensive electric cutter tool for rapidly cutting foam in the embodiment of the invention not only comprises half-moon-shaped cutter heads, but also comprises any cutter head which is flexibly replaced so as to cut different shapes according to different cutting requirements, all the cutter heads cut materials such as foam by adopting a hot cutting method, and in fact, people in the field begin to develop around the hot cutting method, so that the cutting end face is basically smooth and free of scraps, and if the effect of the hot cutting method is further exerted, the technical scheme is further deepened from two angles of various users and cutting objects, and from the fact that the cutter is held by the user to be in a certain angle with the cutting object, the cutter head can cut the required different shapes in a labor-saving and zero-error way, and in fact, a coherent innovative scheme is adopted, and different operation processes are realized by the technical scheme:

for example, when students in schools perform art designing operation or housewives perform material cutting, firstly, a required cutter head is selected, the fixed end seat 4 and the handle rotating part 5 are easily and fixedly assembled by utilizing an anti-insertion structure, and the cutting mode of any cutter head is hot cutting, so that zero error operation is performed on the basis of ensuring smooth cutting end face without scraps, then, the angle of the handle rotating part 5 and a cutting object, which is most convenient for cutting, is adjusted to perform cutting, thereby further realizing flexible and labor-saving cutting of materials with required shapes, and after the operation is finished, the handle rotating part 5 is reversely rotated back to a linear handle state without influencing storage; for example, when a worker in a factory performs foam cutting, the worker can stand or sit in the middle area, put the object to be cut on a cutting platform around the worker and form an annular cutting assembly line, and the worker can hold the electric cutting tool to perform cutting one by one in the annular range, even if the worker meets the need of cutting different shapes, the worker does not need to leave the area, and only needs to replace the required tool bit by himself.
