Description

Technical Field

[0001] The present invention relates to an adhesive tape cutter, and in particular to an adhesive tape cutter which can easily adhere adjacent surfaces of an adhered object which form a certain angle with each other at one time. Background Art

[0002] Generally speaking, tape refers to a tool that is applied with adhesive on one side to stick to an object. The tape is in the form of a strip and rolled into a roll. It is cut into appropriate lengths when used. The tape is produced in various widths according to its use. As one of the most commonly used tapes, the sealing tape used for packaging cartons can be taken as an example.

[0003] Before products are delivered by express or mail, they need to be packaged with needles or bubble pads, which requires the use of sealing tape. During the packaging process, a knife or scissors can be used to repeatedly cut the sealing tape into a certain length, but this causes a lot of inconvenience for the workers who are mainly engaged in packaging work. In order to solve the above inconvenience, a tape cutter that can install tape and is equipped with a blade that can cut the tape has been developed.

[0004] In addition, when sealing a carton, it is necessary to tape one side (the upper side of the carton) covering the open entrance and the other side (the side of the carton) at a certain angle thereto at once. That is, in order to firmly seal the direction, it is necessary to start from one side of the carton and pass over the upper side of the carton covering the entrance and tape to the other side of the carton, and the tape cutter only provides the function of cutting the tape with a blade while leading the tape stored inside to the outside. Even if the tape cutter is used, the operator needs to rotate the carton so that one side of the carton, the upper side of the carton and the other side of the carton face upward in turn and tape, or bend the arm to tape while holding the tape cutter, which increases the burden on the operator and reduces the work efficiency. Summary of the invention

[0005] The present invention aims to solve the existing problems as described above, and its purpose is to provide a tape cutter that can complete the operation without rotating the carton or bending the operator's arms when pasting adjacent pasted surfaces that form a certain angle with each other, thereby preventing the user from being injured and improving the working efficiency.

[0006] In order to achieve the above-mentioned purpose, the tape cutter of the present invention comprises: a cutter body, in which a roll-shaped tape accommodated inside can be led out to the outside through a lead-out hole formed on the bottom surface, and a blade can be provided to cut the led-out tape, and in the cutter body, a sticking induction component is provided, which is formed downward from the front side adjacent to the lead-out hole and the non-sticking surface of the tape contacts the rear and is led out, thereby rotating forward after being supported.

[0007] In addition, the pasting induction component may include: a rotating shaft, formed along the width direction on the inner side of the cutter body; and a pasting induction piece, which is rotatably combined with the rotating shaft and configured downward, and in the rotating shaft, a snap-in protrusion can be formed by protruding in a direction that will not interfere with the rotation of the pasting induction piece, and the snap-in protrusion can achieve elastic snap-in when subjected to the force of rotating the pasting induction piece forward, and can be released when subjected to a force of a certain magnitude or more.

[0008] In addition, in the cutter body, a supporting component that can elastically engage the engaging protrusion can be provided inside, and the supporting component can include a supporting member that is elastically supported by being formed in a manner in which the end portion is located on the upper side adjacent to the end portion of the engaging protrusion.

[0009] Furthermore, the support member may be formed in such a manner that a bottom surface of a distal end portion is inclined upward toward the rear.

[0010] Furthermore, the adhesion inducing member may be restored to its original position by elastic force after rotating forward.

[0011] In the present invention, for adjacent adhered surfaces that form a certain angle with each other, when the cutter body is moved across the other adhered surface in a state where the downward-facing adhesion induction component is adjacent to one adhered surface, the tape can be adhered to one adhered surface with the support of the adhesion induction component, and then the tape can be adhered to the other adhered surface without interfering with the adhesion induction component by causing the adhesion induction component to rotate forward along with the movement of the cutter body.

[0012] Thereby, the adjacent surfaces to be pasted can be pasted at one time without rotating the pasted object or bending the operator's arm, thereby preventing the user from being injured and improving the working efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In the present invention, a tape cutter is provided. When adhering to adjacent adhered surfaces which form a certain angle with each other, the operation can be completed without rotating a carton or bending the operator's arms, thereby preventing the user from being injured and improving the operation efficiency. The invention is characterized in that it comprises: a cutter body, in which a roll-shaped tape accommodated inside can be led out to the outside through a lead-out hole formed on the bottom surface, and a blade is provided so that the led-out tape can be cut; in the cutter body, a sticking induction component is provided, which is formed downward from a front side adjacent to the lead-out hole and the non-sticking surface of the tape contacts the rear and is led out, thereby rotating forward after forming support.

[0019] The scope of the claims of the present invention is not limited to the embodiments described below, but can be implemented in various modifications by a person having ordinary knowledge in the relevant technical field without departing from the technical spirit of the present invention.

[0020] Next, we will refer to Figures 1 to 9 The tape cutter of the present invention will be described in detail.

[0021] The adhesive tape cutter of the present invention is as follows Figures 1 to 3 As shown, the cutter body A includes a cutter body A, which can be used to draw out the roll-shaped adhesive tape 10 stored inside to the outside, and is equipped with a blade 120 that can cut the drawn-out adhesive tape 10.

[0022] The cutter body A can be formed in various forms, such as Figures 1 to 3 As shown, it is preferred that the inside has a structure for installing the roll-shaped adhesive tape 10 and is preferably constructed in the form of a box whose bottom surface is entirely or partially in contact with the adhered object in order to press the adhesive tape 10 that is drawn out and adhered to the adhered object.

[0023] As a specific example, the cutter body A can be constructed in the form of a box with a bottom surface excluding the front end and one side surface open and an empty interior. A mounting ring 151 for the tape 10 to be embedded can be formed on the other side, and in order to prevent the tape 10 embedded in the mounting ring 151 from escaping to one side, an anti-escaping ring 152 coupled to one side of the mounting ring 151 can be provided.

[0024] The tape 10 received in the cutter body A can be led out to the outside through the open bottom surface. At this time, in order to specify the position where the tape 10 is led out, it is preferable to form a lead-out hole 110 on the bottom surface of the cutter body A. As an example, the lead-out hole 110 can be formed as follows: Figure 3 The above-mentioned method is formed between the bottom surface of the front end of the unopened cutter body A and the lead-out guide pin 140 formed at a certain distance from the rear along the width direction of the cutter body A. By this, the adhesive tape 10 embedded in the mounting ring 151 and torn off can be led out to the outside through the lead-out hole 110 formed between the bottom surface of the front end of the cutter body A and the lead-out guide pin 140. However, the lead-out hole 110 can be formed in various forms according to the form of the cutter body A, and is not limited to the above example.

[0025] In addition, the blade 120 provided in the cutter body A is as shown in FIG. Figures 1 to 3 As shown, the blade 120 may be provided at the front end of the cutter body A, and may be not only integrally formed with the cutter body A, but may also be separated from the cutter body A and replaced. In addition, although not shown in the drawings, the blade 120 may also be provided inside the cutter body A, so that it is ejected to the outside under the operation of the user and the tape 10 is cut.

[0026] In the present invention, in order to facilitate pasting of adjacent pasted surfaces that form a certain angle with each other at one time, a pasting induction component 200 is provided in the cutter body A. The certain angle refers to the angle formed between adjacent pasting surfaces among a plurality of pasted surfaces forming the pasted object. As an example, when the pasted object is a carton, the angle between adjacent pasted surfaces is usually 90 degrees. Therefore, for the convenience of explanation, the following content will be explained based on the premise that the certain angle is 90 degrees, but it is not limited to this, and it can also be an acute angle or an obtuse angle.

[0027] Paste the induction component 200 as Figures 1 to 4 As shown, it can be formed downward on the front side adjacent to the lead-out hole 110 so that the pasted surface of the tape 10 led out through the lead-out hole 110 contacts the rear thereof. Figure 6As shown, when the pasting guide member 200 is vertically formed, the tape 10 led out to the outside through the lead-out hole 110 can be vertically led downward while contacting the rear of the pasting guide member 200.

[0028] The pasting guide member 200 formed downward can rotate forward, and a support will be formed first before rotating forward, so that the tape 10 led out to the outside and located at the rear can be pasted onto the surface to be pasted. The support of the pasting guide member 200 as described above can be achieved in various ways. As an example, the pasting guide member 200 can be elastically supported.

[0029] For this purpose, the pasting guide member 200 can include, for example, a rotating shaft 210 and a pasting guide piece 220. As Figures 1 to 5 shown, the rotating shaft 210 can be formed along the width direction of the cutter body A near the bottom surface adjacent to the lead-out hole 110 inside the cutter body A, and the pasting guide piece 220 can be coupled to the rotating shaft 210 and arranged downward so as to rotate forward together with the rotating shaft 210. As a specific example, the pasting guide piece 220 can be formed in a "匚" shape and arranged in an upwardly open manner, and both ends can be coupled to both ends of the rotating shaft 210 protruding from both side surfaces of the cutter body A.

[0030] On the rotating shaft 210, a clamping protrusion 211 can be protrudingly formed in a direction that does not interfere with the rotation of the pasting guide piece 220, such as the front. The clamping protrusion 211 can be elastically clamped when subjected to the force that rotates the pasting guide piece 220 forward, and then the clamping is released when subjected to a force in the same direction above a certain level.

[0031] As an example, the cutter body A can be internally equipped with a support member 300 that can elastically clamp the clamping protrusion 211. The support member 300 as Figures 1 to 5 shown can include: a support piece 310 formed in such a way that its end portion is located on the upper side adjacent to the end portion of the clamping protrusion 211 when the pasting guide piece 220 is arranged downward and thereby elastically supported.

[0032] As a specific example, as Figure 4 shown, a support installation portion 130 for installing the support piece 310 can be provided inside the front end portion of the cutter body A. The front end portion of the support piece 310 can be located inside the support installation portion 130 and arranged rearward, so that the remaining portion except the front end portion protrudes from the support installation portion 130. As Figure 5As shown, in order to prevent the support member 310 in the support installation portion 130 from being detached while allowing it to move in the up and down directions, a guide piece 311 can be protruded along both sides at the front end of the support member 310, and a moving passage 133 that can accommodate the guide piece 311 can be formed in the support installation portion 130 along the up and down directions.

[0033] In addition, in order to elastically clamp the clamping protrusion 211 with the aid of the support member 310, a first support spring 320 and a second support spring 330 for applying elastic force to the support member 310 may be formed on the support component 300. Figure 4 as well as Figure 5 As shown, a first spring installation passage 131 communicating with the moving passage 133 can be formed between the moving passages 133 for accommodating the guide pieces 311 on both sides of the support member 310 in the support installation portion 130, and the first support spring 320 can be formed in a manner that one end contacts the first spring installation passage 131 and the other end contacts the upper end of the support member 310. In addition, a second spring installation passage 132 can be formed forward from the lower end of the first spring installation passage 131 in the support installation portion 130, and the second support spring 330 can be formed in a manner that one end contacts the front end of the second spring installation passage 132 and the other end contacts the front end of the support member 310. At this time, in order to allow the second support spring 330 to play an elastic role, the support member 310 is required to be movable in the front-to-back direction, so it is preferable that the first spring installation passage 131 and the moving passage 133 are formed in a manner that the lower portion thereof has a larger width in the front-to-back direction than other portions. For example, the lower portion of the first spring installation passage 131 and the lower portion of the moving passage 133 may be formed such that the width in the front-rear direction gradually increases downward.

[0034] Thus, the support member 310 can be elastically acted downward by the first support spring 320, and can also be elastically acted backward by the second support spring 330. As described above, the guide piece 311 of the support member 310 to which the first support spring 320 and the second support spring 330 exert elastic action is accommodated in the moving passage 133, and thus will not be separated from the support mounting portion 130.

[0035] In the present invention as described above, the process of realizing elastic engagement and releasing engagement of the engaging protrusion 211 is as follows: Figure 6As shown, the end portion protruding from the support member 310 toward the support mounting portion 130 is located on the upper side adjacent to the end portion of the engaging protrusion 211 when the pasting inducing member 220 is arranged downward. When the pasting inducing member 200 is subjected to a force for rotating the pasting inducing member 200 forward, the support member 310 will not move before being subjected to a force greater than the elastic force of the first support spring 320 and the second support spring 330, so that the engaging protrusion 211 is elastically engaged.

[0036] Next, when subjected to a force greater than the elastic force of the first support spring 320 and the second support spring 330, as shown in FIG. Figure 7 as well as Figure 8 As shown, the end portion of the engaging protrusion 211 will push the end portion of the support member 310 forward while pushing the end portion of the support member 310 upward, thereby releasing the engagement with the support member 310. At this time, in order to allow the engaging protrusion 211 to easily release the engagement with the support member 310, the support member 310 is preferably formed in a manner in which the bottom surface of the end portion is tilted upward toward the rear. That is, the end portion of the engaging protrusion 211 located on the lower side of the support member 310 can push up the end portion of the support member 310 and move upward along the bottom surface of the end portion of the support member 310 when subjected to a force above a certain level, thereby releasing the engagement with the support member 310. Thereby, the elastic engagement between the engaging protrusion 211 and the support member 310 will be released, thereby allowing the pasting induction component to be as shown in the figure. Fig. 9 Rotate forward in the manner shown.

[0037] In order to enable the sticking inducing member 200 rotating forward as described above to play a role in pressing the adhesive tape 10 stuck to the sticking surface, the portion of the bottom surface of the front end portion of the cutter body A where the sticking inducing member 200 rotating forward is arranged may be formed in an upwardly concave shape. Thus, the sticking inducing member 200 rotating forward and received in the concave portion of the bottom surface of the front end portion of the cutter body A can press the adhesive tape 10 stuck to the sticking surface together with the non-concave portion of the front end portion of the cutter body A.

[0038] That is, in the present invention, for adjacent adhered surfaces that form a certain angle with each other, such as Figures 6 to 9As shown, when the cutter body A is moved across the other surface to be adhered in a state where the sticking induction member 200 facing downward is adjacent to one surface to be adhered, the adhesive tape 10 is adhered to one surface to be adhered with the support of the sticking induction member 200, and then the sticking induction member 200 is rotated forward along with the movement of the cutter body A, and the adhesive tape 10 is adhered to the other surface to be adhered without interfering with the sticking induction member 200. In this way, the adjacent surfaces to be adhered can be adhered at one time without rotating the adhered object or bending the operator's arm, thereby preventing the user from being injured and improving the work efficiency.

[0039] Furthermore, in order to allow the adhesion inducing member 200 rotated forward to resume its original function, the adhesion inducing member 200 may be restored to its original position by elastic force after being rotated forward.

[0040] As an example, Figure 4 as well as Figure 5 As shown, the sticking inducing member 200 can be elastically reset by a reset spring 230 provided on the rotating shaft 210, and the reset spring 230 can be a torsion spring. In order to apply elastic force by the reset spring 230 composed of a torsion spring, the reset spring 230 can be wound around the portion of the rotating shaft 210 adjacent to the other side of the cutter body A. In addition, one end of the reset spring 230 protruding from the wound portion can be formed in a state of being fixed by a first spring fixing protrusion 212 formed protruding from the rotating shaft 210, and the other end protruding from the wound portion can be formed in a state of being fixed by a second spring fixing protrusion 160 formed protruding inward from the other side of the cutter body A.

[0041] Thereby, when the force pressing the tape 10 adhered to the adhered surface is released, the adhesion inducing member 200 that has rotated forward can be rotated backward by the elasticity of the return spring 230 and repositioned downward.
