Description

Technical Field

[0001] The utility model relates to the technical field of tape cutting, in particular to a tape cutting device. Background Technique

[0002] A tape cutting device is a commonly used tape shearing tool. Its principle is that through the contact between the tape and the blade, the blade cuts the tape into the length required by the user. The appearance of the tape cutting device brings more accurate cutting accuracy and saves the trouble of the user using a small knife to cut in the past. Most tape cutting devices on the current market can adapt to the cutting of tapes with different diameters, but they cannot be applied to the cutting of tapes with different widths. If a tape cutting device with a large width is used to install a narrow tape, the narrow tape is likely to slide along the fixed axis during the pulling process, resulting in the cutting length being affected by the sliding and unable to be accurately controlled. And a tape cutting device with a small width cannot be used to install a tape with a large width. Therefore, how to make the tape cutting device better adapt to tapes with different widths has become the direction of upgrading and optimization of the tape cutting device.

Thus, the features defined with "first", "second", and "third" may explicitly or implicitly include one or more of such features.

[0042] It should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0043] The following will further illustrate the technical solutions of the embodiments of a tape cutting device of the present utility model in conjunction with the attached Figures 1 to 9 drawings and through specific implementation manners.

[0044] A tape cutting device, as Figure 1 shown, includes a base body 11, a tape cutting unit 12, a connection unit A, and two sets of tape fixing components;

[0045] As Figure 7 shown, the base body 11 is provided with a tape accommodating area 111, a cutting area 112, and two side mounting areas 113 arranged back to back. The tape cutting unit 12 is installed in the cutting area 112, and the connection unit A is provided in the side mounting area 113;

[0046] The tape fixing assembly includes a side plate body 21, a tape fixing structure 22, and a connecting unit B; the tape fixing structure 22 and the connecting unit B are both arranged inside the side plate body 21, and two sets of the tape fixing assemblies are respectively oppositely arranged in different side mounting areas 113. The tape fixing assembly is detachably connected to the connecting unit A through the connecting unit B, and the two tape fixing structures 22 are respectively oppositely located in the tape accommodating area 111;

[0047] The two tape fixing structures 22 can be respectively independently used to limit a narrow tape, or the two tape fixing structures 22 can be jointly used to limit the same wide tape.

[0048] Specifically, through the arrangement of the two tape fixing structures 22 in the tape cutting device proposed by the present utility model, it can be realized that a single tape fixing structure 22 fixes a narrow tape, that is, two narrow tapes can be fixed simultaneously or only one tape fixing structure 22 is used to fix one narrow tape. In addition, it can also be realized that the two tape fixing structures 22 fix the same wide tape, solving the problems that the existing tape cutting device is only applicable to the installation of tapes of one width and has low applicability, and that the narrow tape is prone to slide along the fixed axis during cutting, and the cutting length is affected by the sliding and cannot be accurately controlled.

[0049] The instructions for using the two tape fixing structures 22 to be respectively independently used to limit a narrow tape are as follows: Install a single narrow tape in any one of the tape fixing structures 22, and another narrow tape can also be installed in the other tape fixing structure 22. At the same time, connect the connecting unit A and the connecting unit B, which can prompt the base body 11 and a single set of the tape fixing assemblies to complete the connection. The narrow tape will be fixed by the single set of the tape fixing structures 22, and the tape cutting device is also assembled and can be used by the user. When the user needs to remove the tape, the user separates the connecting unit A and the connecting unit B, releases the tape from the fixing effect of the single tape fixing structure 22, and takes out the tape.

[0050] The instructions for using the two tape fixing structures 22 to jointly limit the same wide tape are as follows:

[0051] Detach the connecting unit A and the connecting unit B on either side, and install the wide tape in any one of the tape fixing structures 22

[0052] Then connect the detached connecting unit A and the connecting unit B, so that the wide tape is aligned with the other tape fixing structure 22, and the two tape fixing structures 22 complete the limitation of the same wide tape and can be used by the user.

[0053] It should be noted that the above-mentioned narrow tape and wide tape refer to tapes with different widths. The width of the narrow tape is less than that of the wide tape. There is no limitation on how narrow the narrow tape is and how wide the wide tape is. In actual production, the size of the tape fixing structure 22 can be determined according to production requirements. The tape that can be fixed by a single tape fixing structure 22 can be defined as a narrow tape, and the tape that requires two tape fixing structures 22 to fix it together can be defined as a wide tape. "Narrow" and "wide" are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific size. Therefore, it should not be construed as a limitation to the present invention.

[0054] As Figures 1 to 3 shown, the tape fixing structure 22 includes a plurality of elastic adjustment units 222 and a plurality of elastic stretchable bands 223; the plurality of elastic adjustment units 222 are circumferentially and equally spaced with the same center on the inner side of the middle part of the side plate body 21;

[0055] The elastic adjustment unit 222 includes a spring holder 2221, a spring limiting part 2222, a spring 2223 and a support rod 2224;

[0056] The spring holder 2221 and the spring limiting part 2222 are respectively installed on the inner side of the middle part of the side plate body 21. The spring limiting part 2222 has a guide groove extending towards the center of the circle. The spring 2223 is limited and movable in the guide groove. The fixed end of the spring 2223 is connected to the spring holder 2221, and the movable end of the spring 2223 is connected to one end of the support rod 2224. A sleeving area 2224A is provided on the outer circumference of the support rod 2224. The sleeving area 2224A is used to limit the elastic stretchable band 223 and allows the elastic stretchable band 223 to elastically connect two adjacent elastic adjustment units 222.

[0057] Specifically, through the arrangement of a plurality of elastic adjustment units 222 and a plurality of elastic stretchable bands 223, when any support rod 2224 is pulled, the other support rods 2224 can move inwards or outwards synchronously, so that the tape fixing structure 22 has an automatic adaptation and fixing function to adapt to the limiting of tapes with different diameters. The specific principle is as follows: As Figures 4 to 5As shown, the spring fixer 2221 fixes one end of the spring 2223, and the guide groove of the spring limiter 2222 is provided to ensure that the spring 2223 can reciprocate in its own extension direction and in the direction toward the center of the circle; within its elastic range, the spring 2223 and the elastic stretch band 223 respectively connected to the support rod 2224 are both kept in a stretched state, and the spring 2223 and the elastic stretch band 223 simultaneously exert a force on the support rod 2224 so that the support rod 2224 is in a stable state; when the tape is cut When there is no tape inside the cutting device, this steady state is called a no-tape steady state; when there is tape inside the tape cutting device, the inner frame of the tape will have an inward squeezing effect on the support rod 2224, and this inward squeezing effect will cause the spring 2223, the elastic stretch band 223 and the support rod 2224 to reach a new steady state again, which is called a tape steady state; according to this principle, as long as the tape installation size of the tape cutting device is not exceeded, tapes of different diameters can be automatically adapted without manual adjustment.

[0058] In a specific embodiment, the support rod 2224 is a cylindrical structure, and two circular rings are provided on the outer periphery of one end of the support rod 2224; a sleeve area 2224A for the elastic stretch band 223 to be sleeved is formed between the two circular rings, and the sleeve area 2224A is formed on the support rod 2224 by the two circular rings so as to limit the elastic stretch band 223 to the outer periphery of the support rod 2224.

[0059] In a specific embodiment, the spring retainer 2221 is a cylindrical structure, the bottom surface of which is connected to the inner side of the side plate body 21. The side surface of the spring retainer 2221 is provided with an inwardly concave and sloped annular groove, the width and curvature of which match the width and curvature of the round hook at one end of the spring 2223. The spring 2223 is hooked and fixedly connected to the annular groove of the spring retainer 2221 via the round hook. The annular groove can well fix one end of the spring 2223 in the annular groove. When the spring 2223 is damaged and needs to be replaced, the sloped annular groove also makes it easy to remove and replace the spring 2223.

[0060] like Figures 4 to 6As shown, the elastic adjustment unit 222 further includes a limit disk 2224B, which is rotatably installed on the other end face of the support rod 2224. When the limit disk 2224B rotates outward, a clamping groove is formed between the limit disk 2224B and the spring 2223. The clamping groove is used to prevent the narrow tape from detaching from the elastic adjustment unit 222. When the limit disk 2224B rotates inward, the narrow tape can be detached from the elastic adjustment unit 222.

[0061] Through the arrangement of the limit disk 2224B, when installing the narrow tape, the tape fixing structure 22 on one side can be used alone. To prevent the narrow tape from detaching during rotation, rotating the limit disk 2224B can limit and clamp the inner frame of the narrow tape in the clamping groove to fix the narrow tape. When the narrow tape needs to be detached, the limit disk 2224B can be rotated to make the clamping groove disappear, and the narrow tape can be detached from the tape fixing structure 22.

[0062] Further, the shape of the limit disk 2224B is a semi - disk or a triangular plate; when the limit disk 2224B is a semi - disk, the center of the straight edge of the semi - disk is the rotation center; when the limit disk 2224B is a triangular plate, the center of any long side of the triangular plate is the rotation center.

[0063] Specifically, using a semi - disk or a triangular plate as the limit disk 2224B is simpler and more stable in structure and has a lower production cost compared with a square plate or a circular plate. It should be noted that if it is a square - plate or circular - plate structure, the rotation point is any point on the outer contour of the square plate or circular plate.

[0064] In a specific embodiment, the movable end of the spring 2223 passes through the inside of the support rod 2224 along the axial direction of the support rod 2224 and protrudes from the other end face of the support rod 2224. The end of the spring 2223 protruding from the other end face of the support rod is rotatably installed with the limit disk 2224B. By passing the spring 2223 through the support rod 2224 and rotatably installing the limit disk 2224B at the protruding end, the rotatable movement of the limit disk 2224B is realized, while adding the function of clamping the narrow tape and reducing the addition of parts.

[0065] As Figures 4 to 6 shown, the tape fixing structure 22 further includes a central column 221. A plurality of elastic adjustment units 222 are circumferentially distributed at equal intervals and with equal angular differences around the center of the central column 221 on the inner side of the middle part of the side - plate body 21; the two central columns 221 in the two tape fixing structures 22 are designed to be sleeved with each other, and one central column 221 is sleeved on the outer circumference of the other central column 221.

[0066] The installation stability of the tape cutting device is improved by adding a center column 221. Specifically, the center columns 221 that are nested with each other have two functions. When the two groups of the tape fixing components are connected to the tape cutting component, the two side panel bodies 21 are easily affected by external forces and subjected to uneven force, and are over-extruded, resulting in the two tape fixing structures 22 losing their fixing effect on the tape, and may also cause the connection between the connecting unit A and the connecting unit B to be disconnected; the function of the center column 221 is that when the two groups of the tape fixing components are connected to the tape cutting component, the two center columns 221 are nested and relatively fixedly installed with each other, so that the two groups of the tape fixing components are subjected to uniform force and are not easily affected by external forces to cause deformation of the internal structure or disconnection from the tape cutting component; at the same time, it can also provide a support function for the tape after the elastic adjustment unit 222 is damaged, so that the tape still remains in the tape cutting device.

[0067] Preferably, the spring limiting portion 2222 is composed of two annular belts facing each other, one end of the two annular belts is connected to the inner side of the side plate body 21, and the other ends of the two annular belts are spaced apart to form a gap; the size of the cavity formed between the two annular belts matches the size of the spring 2223, and the spring 2223 is embedded in the cavity, and the cavity is the guide groove.

[0068] The spring 2223 is hidden in the guide groove, which can well resist the influence of external vibration or shaking; at the same time, a gap is left at one end of the spring limiting portion 2222, which also facilitates the removal and replacement of the spring 2223.

[0069] Furthermore, the number of the elastic adjustment units 222 is three; the elastic stretch bands 223 are rubber bands, and the number of the elastic stretch bands 223 is three.

[0070] The more the elastic adjustment units 222 are, the better the tape fixing effect is; however, if the number of the elastic adjustment units 222 is too large, the tape fixing structure 22 becomes complicated; Figures 4 to 5 As shown, when the number of the elastic adjustment units 222 is three, the tape fixing structure 22 just forms a stable equilateral triangle structure. Such a structure ensures the stability of the tape fixing effect while being relatively simple in structure and relatively cheap in cost.

[0071] Furthermore, at least two tape cutting units 12 are provided. The base body 11 has a concave structure with high platforms on both sides. Each of the high platforms is provided with a tape cutting unit 12, and the cutting edges of the two tape cutting units 12 face in opposite directions. The connecting unit A is respectively arranged on the side surfaces of the high platforms. An opening groove is provided on the outer side of the high platform, and the notch of the opening groove communicates with the top and the outer side of the high platform. The tape cutting unit 12 includes a blade, and the blade is accommodated and installed in the opening groove.

[0072] Specifically, as Figures 1 to 3 shown, the tape is installed in the concave portion of the base body 11 (i.e., the tape accommodating area 111) through the two tape fixing structures 22. The concave portion of the base body 11 is an area provided for the tape to roll during use. At the same time, two relatively arranged tape cutting units 12 are provided. Whether the tape is installed forward or backward, the tape can select the corresponding tape cutting unit 12 for cutting, which well solves the problem that the tape cannot be cut when it is installed reversely. During specific use, two rolls of narrow tapes can be respectively installed reversely in the tape cutting device at the same time, and bidirectional cutting can be achieved.

[0073] The opening groove matches the size of the blade, which can make the blade be hidden in the opening groove as much as possible, playing a certain protective role for the user when cutting the tape. The blade is serrated, which can make it easier for the user to cut the tape. At the same time, the end of the blade is bent and faces outward, making the tape cutting effect more neat.

[0074] Furthermore, as Figure 8 shown, the side plate body 21 is divided into a middle part and two side parts. The two side parts are respectively horizontally connected to both sides of the middle part, and a concave avoidance area E is formed between the two side parts and the middle part. The tape fixing structure 22 is installed on the inner side of the middle part, and the connecting unit B is respectively installed on the inner sides of the two side parts.

[0075] Specifically, a concave area E is provided between the middle part and the two side parts of the side plate body 21. The concave area E is an area that can provide the user with a space to turn over the tape to pull out the tape opening or reach out to replace the tape.

[0076] When the user wants to remove the tape, the user can reach in through the recessed area E and squeeze all the support rods 2224 inward, breaking the original steady state with the tape and releasing the self-adaptive fixing effect of the tape fixing structure 22 on the tape. At the same time, the user also needs to separate the two sets of tape fixing components from the tape cutting component, so that the tape can be taken out from the tape cutting device, and the state of the elastic adjustment unit 222 is also adjusted to the steady state without tape. Similarly, when the user wants to install a new tape, the user can reach in through the recessed area E and squeeze all the support rods 2224 inward, breaking the steady state without tape of the elastic adjustment unit 222. While slipping the new tape over all the support rods 2224, connect the two sets of tape fixing components to the tape cutting component, so that the new tape can be installed into the tape cutting device, and the elastic adjustment unit is also adjusted to the steady state with tape. When the user wants to cut the tape, just select the corresponding blade according to the installation direction of the tape for cutting.

[0077] Preferably, the connecting unit A is a positioning mounting hole, the connecting unit B is a positioning mounting post, the positioning mounting post is detachably inserted into the positioning mounting hole, and the tape fixing component is detachably connected to the positioning mounting hole through the positioning mounting post.

[0078] The structures of the positioning mounting post and the positioning mounting hole are simple. At the same time, the combination and separation of the positioning mounting post and the positioning mounting hole can not only realize the detachable connection between the base body 11 and the two sets of tape fixing components, but also ensure the stability of the connection between the above two after connection. In a specific embodiment, the number of positioning mounting holes is four; two positioning mounting holes are respectively arranged on the side surface of each high platform; the number of positioning mounting posts is four; the four positioning mounting posts match the four positioning mounting holes, and each side is fixed by two points, making the assembled structure more stable.

[0079] As Figure 9 shown, it further includes a plurality of tool boxes 23. The inner side of the tool box 23 is hollowed out, and a connecting unit D is arranged on the edge of the inner side of the tool box 23; a connecting unit C is arranged on the outer side of the side plate body 21; the tool box 23 is detachably connected to the connecting unit C through the connecting unit D.

[0080] The design of the tool box 23 can well provide a storage space for auxiliary tools related to tape cutting for the user, such as marking pens and rulers, etc., making the user more handy when using the tape cutting device.

[0081] Specifically, the connecting unit C is a pair of positioning and mounting buckle seats, and the connecting unit D is a pair of positioning and mounting buckles; the toolbox 23 is detachably connected to the pair of positioning and mounting buckle seats through the pair of positioning and mounting buckles. The structures of the pair of positioning and mounting buckle seats and the pair of positioning and mounting buckles are simple, which can not only realize the detachable connection between the toolbox 23 and the two groups of tape fixing components, but also ensure the stability of the connection between the above two; users can also, according to their own usage requirements, choose to hang multiple toolboxes 23 at the same time when there is enough space outside the side plate body 21.

[0082] The technical principle of the present invention has been described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be construed in any way as a limitation on the protection scope of the present invention. Based on the explanations herein, those skilled in the art can readily conceive of other specific embodiments of the present invention without creative efforts, and these embodiments will fall within the protection scope of the present invention.
