Description

Technical Field

[0001] This invention relates to the field of packaging box technology, and more specifically, to a device for tearing off sealing tape. Background Technology

[0002] Currently, packaging boxes are generally sealed with tape. After the packaging of servers and computer products or components is sealed, some need to be unpacked and reprocessed. During the unpacking process, the sealing tape is difficult to peel off or clean from the surface of the cardboard box. If the operation is not done properly, the sealing tape will tear the cardboard box cover and the cardboard box will peel off and be scrapped.

[0003] The unpacking methods currently in use mainly include:

[0004] The first method is to manually and slowly tear the tape. This method is very inefficient and can easily tear the tape on the surface of the cardboard box.

[0005] The second method involves using a heat gun to blow hot air onto the tape, reducing its stickiness, and then peeling it off by hand. This method increases the workload and also makes it difficult to avoid tearing the cardboard box.

[0006] In summary, how to provide a device for quickly removing the tape from packaging boxes without peeling off the box body is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0077] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0078] The core of this invention is to provide a device for tearing off sealing tape, which can quickly tear off the tape 800 on the packaging box 700 and prevent the box from peeling off.

[0079] This specific embodiment discloses a device for tearing off sealing tape, used to tear off tape 800 adhered to a packaging box 700. The device includes a base 100, a handheld component 200, a pressing component 300, and a heating component 400. The base 100 is placed on the packaging box 700 with partially torn tape 800 and is movable relative to the length of the tape 800. The handheld component 200 is mounted on the base 100, and an outlet 500 is provided between the handheld component 200 and the base 100. The torn end of the tape 800 extends through the outlet 500 into the base 100. The first side; the pressing component 300 is disposed on the second side of the base 100. The pressing component 300 includes two pressing members 310 disposed opposite to each other. The two pressing members 310 can be close to or far from each other. The two pressing members 310 press the packaging box 700 along the two side edges of the tape 800 in the width direction. The heating component 400 is disposed on the lower surface of the handheld component 200 or the lower surface of the base 100. It is used to attach and heat the surface of the tape 800 that has not been torn off. By moving the base 100, the heated tape 800 is passed through the outlet 500 to the first side to tear off the tape 800 stuck on the packaging box 700.

[0080] The relationship between the device for removing the sealing tape and the packaging box 700 during use is as follows: Figure 1 As shown.

[0081] It should be noted that, before the formal use of the device for tearing off the sealing tape mentioned in this specific embodiment, in order to facilitate the subsequent exit of the tape 800 through the outlet 500, a portion of the tape 800 can be manually torn off first, and the torn tape 800 can be passed through the device for tearing off the sealing tape along a preset path and exited through the outlet 500.

[0082] In addition, an automatic tape-threading structure can be set up so that, at the initial stage of the device for tearing off the sealing tape, the torn end of the tape 800 is picked up by a suction cup or other related structure, and the torn part of the tape 800 is threaded through a preset path, which is determined according to the actual situation.

[0083] In using the device for tearing off sealing tape provided in this specific embodiment, first adjust the spacing between the pressing members 310 so that the spacing between the two pressing members 310 is just equal to or slightly greater than the width of the tape 800 to be torn. Then press the pressing members 310 onto both sides of the tape 800 to be torn in the width direction, so that the two pressing members 310 are as close as possible to the two side edges of the tape 800 in the width direction, so as to avoid damaging the surface of the box in contact with the tape 800 during the process of tearing off the tape 800; then start the heating assembly. 400, to bring the temperature of the heating component 400 to a suitable level and to make the heating component 400 adhere to the surface of the tape 800 to be removed, and the heating component 400 can completely cover the tape 800 in the width direction of the tape 800. The device for tearing the sealing tape is controlled to move forward continuously. The heating component 400 heats different positions of the tape 800 along the length direction of the tape 800. After heating, the viscosity between the tape 800 and the box body is reduced, making it easier to tear. The torn tape 800 is then passed out through the outlet 500.

[0084] The device for tearing off sealing tape provided in this specific embodiment can effectively prevent the box from peeling off during the process of tearing off the tape by pressing the box surface on both sides of the tape 800 with the pressing member 310; in addition, by setting the heating component 400, the efficiency of tearing off the tape 800 can be effectively improved.

[0085] Based on the above embodiments, such as Figure 5 As shown, the base 100 is provided with a guide ramp 110, such as Figure 7 As shown, the handheld assembly 200 is provided with a guide roller 210, and the torn tape 800 is conveyed along the guide roller 210 and the guide ramp 110 to the outlet 500.

[0086] The specific structural form of guide roller 210 is as follows: Figure 20 As shown, the surface of the guide roller 210 is smooth to minimize friction with the tape 800; as Figure 9 As shown, the handheld assembly 200 is provided with a guide roller mounting hole 2101. The guide roller 210 is rotatably mounted in the guide roller mounting hole 2101.

[0087] On the other hand, when the path of the tape 800 after being torn is relatively tortuous and requires multiple adjustments to the direction, multiple guide rollers 210 can be set up to form a guide roller group. The torn tape 800 passes through multiple guide rollers 210 in sequence so that the tape 800 can smoothly pass out of the outlet 500.

[0088] Multiple guide rollers 210 are provided to accommodate situations where the output path of the tape 800 is complex and requires multiple direction adjustments, so that the tape 800 can pass through smoothly.

[0089] In this specific embodiment, the guide slope 110 and guide roller 210 can be set to guide the tape 800 to pass through, so as to prevent the tape 800 to be torn from getting stuck inside the device for tearing off the sealing tape, so that the tape 800 can pass through smoothly.

[0090] Based on the above embodiments, the device for tearing off the sealing tape further includes a glue-drawing roller 120 rotatably disposed on the base 100 and a compression roller 220 rotatably disposed on the handheld component 200. The tape 800 passes between the glue-drawing roller 120 and the compression roller 220, and the friction between the glue-drawing roller 120 and the tape 800 and the friction between the compression roller 220 and the tape 800 cause the tape 800 to be output.

[0091] like Figure 18 As shown, the surface of the glue-drawing roller 120 is provided with spiral recessed textures to increase friction, such as... Figure 19 As shown, the outer surface of the extrusion roller 220 is provided with axially extending strip-shaped protrusions to increase friction; during the actual installation process, such as... Figure 4 As shown, the base 100 is provided with a glue-drawing roller shaft hole 1201, and the glue-drawing roller 120 shaft is rotatably mounted in the glue-drawing roller shaft hole 1201, as shown. Figure 9 As shown, the handheld component 200 is provided with a compression roller mounting position 2201. The compression roller 220 is rotatably mounted on the compression roller mounting position 2201 of the handheld component 200. Specifically, the compression roller mounting position 2201 can be configured as an arc-shaped recess for accommodating the compression roller 220.

[0092] In practical use, such as Figure 3 As shown, the heating component 400 heats the tape 800 to be torn. After heating, the viscosity between the tape 800 and the packaging box 700 decreases, making it easier to tear. During the tearing process, the device for tearing the sealing tape moves forward continuously, specifically towards the tape 800 to be torn. The tape 800 to be torn is wrapped around the guide roller 210, passes through the guide inclined surface 110, and passes between the glue-drawing roller 120 and the extrusion roller 220. Under the action of the friction between the glue-drawing roller 120 and the extrusion roller 220, the tape 800 is continuously conveyed outward.

[0093] On the other hand, the device for removing the sealing tape also includes a roll shaft rotatably disposed on the base 100 and located outside the outlet 500, and a roll shaft power component for driving the roll shaft to rotate. The roll shaft is provided with a clamping part or an adhesive part for fixing the tape 800. The base 100 is provided with a U-shaped shaft seat and an openable sealing member disposed at the opening of the U-shaped shaft seat. The roll shaft is disposed in the U-shaped groove of the U-shaped shaft seat.

[0094] In practical use, the initially torn tape 800 needs to be fixed to the roll shaft so that the tape 800 can be continuously wrapped around the outer circumference of the roll shaft when the roll shaft rotates. The end of the tape 800 can be glued and fixed to the roll shaft by the adhesive part, or the end of the tape 800 can be clamped and fixed to the roll shaft by the clamping part, depending on the actual situation.

[0095] The reel power unit can be a rotating structure such as a motor or electric cylinder. The reel power unit drives the reel to rotate. During the rotation of the reel, the torn tape 800 is wound around the reel, realizing the collection of tape 800. After the tape 800 is collected to a certain thickness, the sealing part can be opened, the reel with tape 800 wound on it can be taken out, the tape 800 can be removed, and the reel can be reinstalled to continue collecting tape 800.

[0096] It should be noted that in this specific embodiment, the conveying speed of the roll shaft needs to be determined according to the speed at which the tape 800 is torn off. It is necessary to ensure that there is a certain amount of slack at the connection between the un-torn part and the torn part of the tape 800, and that it is not excessively taut.

[0097] The device for tearing off sealing tape provided in this specific embodiment can pull out the tape 800 through the roll shaft and collect the tape 800. During the collection process, the roll shaft provides a certain amount of power, making it easy to operate.

[0098] In one specific embodiment, such as Figure 2 As shown, the base 100 is provided with a traveling component 600, such as Figure 15 , Figure 16As shown, the traveling component 600 includes a belt 610 and a gear set 620 disposed within the belt 610 and driven to rotate by the belt 610. At least one gear in the gear set 620 meshes with the glue-drawing roller 120 to drive the glue-drawing roller 120 to rotate. The gear set 620 includes a first tension gear 6201 and a second tension gear 6202 located at both ends within the belt 610, and a top support gear 6203 disposed at the middle position within the belt 610. One of the first tension gear 6201 and the second tension gear 6202 meshes with the glue-drawing roller 120. Along the output direction of the conveyor belt 800, a guide roller 210 and a guide ramp 110 are disposed between the heating component 400 and the glue-drawing roller 120. The conveyor belt 800 passes sequentially through the guide roller 210, the guide ramp 110, the glue-drawing roller 120, the extrusion roller 220, and the outlet 500.

[0099] In actual use, when tearing off the tape 800 from the surface of the packaging box 700, such as Figure 1 As shown, the device for tearing off the sealing tape needs to be placed on the surface of the packaging box 700. The heating component 400 heats the tape 800 to be torn. After heating, the device for tearing off the sealing tape is moved. Due to the friction between the belt 610 and the surface of the packaging box 700, the belt 610 will be driven to move. During the conveying process, the belt 610 will drive the first tension gear 6201, the second tension gear 6202, and the top support gear 6203 in the gear set 620 to rotate. The first tension gear 6201 meshes with the glue-drawing roller 120, thereby driving the glue-drawing roller 120 to rotate. During the rotation of the glue-drawing roller 120, the friction between the glue-drawing roller 120 and the tape 800 will drive the tape 800 to be output outward.

[0100] like Figure 5 As shown, the base 100 is provided with a mounting slot 150 for accommodating the traveling component 600, such as... Figure 4 As shown, a gear hole 180 is provided in the mounting groove 150, and the gear in the gear set 620 is rotatably mounted in the gear hole 180.

[0101] In this specific embodiment, the gear set 620 includes a first tension gear 6201, a second tension gear 6202, and a top support gear 6203. The top support gear 6203 can prevent the middle of the belt 610 from becoming loose and does not require an additional power structure, further simplifying the structure of the device for tearing off the sealing tape and reducing costs.

[0102] Of course, in order to prevent slippage between the belt 610 and the packaging box 700, anti-slip textures can be provided on the outer surface of the belt 610, or a traveling power component can be provided to drive at least one gear in the gear set 620 to rotate, so as to provide power for the forward movement of the traveling component 600 and the rotation of the glue-pulling roller 120.

[0103] In one specific embodiment, such as Figure 11 As shown, the heating assembly 400 includes a heating plate 410, a guide post 420, and an elastic element; the heating plate 410 has a heating surface for contacting the tape 800 to be torn off; the guide post 420 is disposed on the upper surface of the heating plate 410 and is installed in the guide hole 250 of the handheld assembly 200; one end of the elastic element is connected to the guide hole 250 and the other end is connected to the guide post 420. Specifically, the elastic element can be set as a spring and sleeved on the guide post 420, depending on the actual situation; the elastic element is compressible in the height direction of the guide post 420 so that the heating plate 410 has elastic displacement in the direction perpendicular to the surface of the tape 800 to be torn off.

[0104] like Figure 6 As shown, the handheld component 200 is provided with fastening screw holes 280, such as... Figure 11 As shown, the guide post 420 in the heating assembly 400 is provided with a screw hole 4201. The screw passes through the fastening screw hole 280 and connects to the screw hole 4201, so that the heating assembly 400 can be detached and installed. Depending on the actual situation, different models of heating assembly 400 can be replaced.

[0105] like Figure 12 As shown, the front end of the heating component 400 is provided with a transition surface 4101, which is a transition arc surface, or it can be a transition slope surface. During the forward movement of the device that removes the sealing tape, there is a certain gap between the transition surface 4101 and the upper surface of the tape 800, which can prevent the protrusion of the tape 800 surface from affecting the normal movement during the movement.

[0106] In this specific embodiment, by setting an elastic element, a certain pre-tightening pressure can be provided to the heating plate 410, so that the heating plate 410 can better fit with the tape 800. In addition, when there are protrusions or depressions on the surface of the tape 800, the heating plate 410 can have a certain lifting space under the action of the elastic element, which can better fit with the tape 800 and improve the tearing efficiency and tearing quality of the tape 800.

[0107] On the other hand, a temperature sensor, an indicator light, and a controller can also be set in the heating assembly 400; the temperature sensor is used to obtain the temperature information of the heating surface in the heating plate 410 and transmit the temperature information to the controller. When the temperature of the heating surface is within a preset range and continues for a preset time, the controller controls the indicator light to light up.

[0108] In practical use, two different usage modes can be set:

[0109] The first method for heating the heating component 400 in the device for removing packing tape includes:

[0110] Obtain the temperature information of the heating plate 410.

[0111] Determine whether the temperature information is within the preset temperature range. If yes, proceed to the next step. If no, obtain the minimum difference between the temperature information and the preset temperature range, and adjust the temperature of the heating plate 410 to the preset temperature range.

[0112] Determine whether the heating plate 410 has been continuously heated at the preset temperature for the preset time. If yes, proceed to the next step; otherwise, control the device for tearing off the sealing tape to maintain its current position until the heating plate 410 has been continuously heated at the preset temperature for the preset time.

[0113] The device for controlling the removal of the sealing tape moves forward a preset distance.

[0114] In the specific implementation of the above method, the heating temperature and heating time of the heating plate 410 can be precisely controlled, which can effectively improve the tearing quality and tearing effect of the tape 800.

[0115] The second method for heating the heating component 400 in the device for removing packing tape includes:

[0116] Obtain the temperature information of the heating plate 410.

[0117] Determine whether the temperature information is within the preset temperature range. If yes, proceed to the next step. If no, obtain the minimum difference between the temperature information and the preset temperature range, and adjust the temperature of the heating plate 410 to the preset temperature range.

[0118] The device that controls the removal of the sealing tape moves forward at a preset speed at a uniform speed.

[0119] In the above method of use, apart from the initial stage of waiting for the heating plate 410 to heat to the preset temperature range, the rest of the time only requires controlling the device for tearing off the sealing tape to move at a uniform speed, making the control process convenient.

[0120] In one specific embodiment, the base 100 is provided with a guide slide shaft and an adjusting member 130.

The control connection hole 3104 is provided with a limit to restrict the axial movement of the adjusting member 130. During the process of screwing the adjusting member 130, the adjusting member 130 rotates relative to the pressing member 310, and at the same time drives the two pressing members 310 to move closer or further apart, so as to adapt to tapes 800 of different widths.

[0123] During the assembly process, the heating component 400 is positioned between two opposing pressing members 310, and the pressing members 310 are provided with a clearance groove 3101 for avoiding the heating component 400, so as to maximize the width of the heating component 400 and enable the same heating component 400 to accommodate tapes 800 of different widths.

[0124] like Figure 14 As shown, the pressing bottom surface 3105 of the pressing member 310 is flat, which allows the pressing bottom surface 3105 to fully contact the tape 800. In order to facilitate the installation of the guide roller 210, a receiving groove 3102 is provided at the rear end of the pressing member 310, which provides a certain installation space for the guide roller 210.

[0125] In actual use, there are often situations where the tape 800 is wrapped more than 1 time and is layered. A sliding cutter can be provided on the base 100.

[0126] Specifically, the cutter can be rotatably mounted on the base 100, or the cutter can be retracted and mounted outside the base 100, or the cutter can be slidably mounted within the space enclosed by the base 100 and the handheld component 200. In actual use, the cutter slides through the power structure to cut the tape 800 in advance.

[0127] To facilitate the insertion of the tape 800 between the guide roller 210, the glue-drawing roller 120, and the extrusion roller 220 within the handheld assembly 200, the handheld assembly 200 can be rotatably mounted on the base 100. Specifically, one end of the handheld assembly 200 is rotatably mounted on the base 100 via a rotating shaft, and a buckle 230 is provided at one end of the handheld assembly 200 and the base 100, while a slot 190 is provided at the other end of the handheld assembly 200 and the base 100 for engaging or disengaging with the buckle 230.

[0128] like Figure 4 As shown, the base 100 is provided with a second rotating shaft hole 160, such as Figure 9 As shown, the handheld component 200 is provided with a first rotating shaft hole 270, and the rotating shaft of the handheld component 200 is installed in the first rotating shaft hole 270 and the second rotating shaft hole 160; as Figure 8 As shown, the handheld component 200 is provided with a snap-fit ​​hole 260, which is used to install the snap-fit ​​230, as shown. Figure 4 As shown, the base 100 is provided with a slot 190, and the buckle 230 includes a main body 2301, a protrusion 2302, a guide 2303, and an elastic pre-tightening member; wherein, the main body 2301 is disposed on the base 100 or the handheld component 200; the protrusion 2302 protrudes from the main body 2301 and is used to engage with the slot 190; the guide 2303 is disposed on the main body 2301 and engages with the guide groove of the base 100 or the handheld component 200 to restrict the movement direction of the main body 2301; The elastic pretensioner is disposed in the guide groove, with one end of the elastic pretensioner abutting against the guide groove and the other end abutting against the guide portion 2303; when the elastic pretensioner is in the first compression state, the protrusion portion 2302 is in the retracted state, and the buckle 230 is disengaged from the slot 190; when the elastic pretensioner is in the second compression state, the protrusion portion 2302 is in the extended state, and the buckle 230 is engaged with the slot 190; the compression amount of the elastic pretensioner in the first compression state is greater than the compression amount of the elastic pretensioner in the second compression state.

[0129] In actual use, pressing the main body 2301 can disengage the protrusion 2302 from the slot 190. At this time, the handheld component 200 can be flipped relative to the base 100 to facilitate the insertion of the tape 800. After the tape 800 is inserted, in order to fix the handheld component 200, flip the handheld component 200 and press the main body 2301 so that the protrusion 2302 corresponds to the slot 190. Then release the main body 2301. Under the elastic force of the elastic pre-tightening member, the protrusion 2302 can be engaged with the slot 190.

[0130] On the other hand, a gripping part 240 that is easy to grip can also be provided on the handheld component 200, and the gripping part 240 is provided with anti-slip texture to prevent slipping.

[0131] like Figure 5 As shown, the base 100 is provided with a pressing part 140 for pressing against the surface of the part of the box 700 where the tape 800 is torn off. The pressing part 140 is located on the rear side of the heating assembly 400. During the process of tearing off the tape 800, since the pressing part 140 is pressed against the surface of the packaging box 700, the surface of the packaging box 700 is not damaged when the tape 800 is torn off, which helps to maintain the integrity of the packaging box 700 and realize reuse.
