Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to a tape sealing machine mechanism. Background Technology

[0002] With the rapid development of the logistics and manufacturing industries, there are increasingly stringent challenges to the equipment in the field of packaging machinery technology. The requirements for the sealing quality and packaging efficiency of packaging boxes have been greatly improved. Generally, automatic or semi-automatic box sealing machines are used to seal packaging boxes. Box sealing machines are mainly used in automated production lines in factories for assembly line operations. The core of the tape sealing machine is the device that applies tape to the area to be sealed on the packaging box. It is used to stick the tape to the area to be sealed on the packaging box and cut the tape.

[0003] For example, Chinese utility model patent CN220243745U describes a tape sealing machine mechanism. Its connector is hinged to a second side plate, and a blade is mounted on the connector. This blade moves in an arc around a point to cut the tape passing between the tape pressure rollers on both sides. For some harder and more resilient tape materials, such as cloth tape and fiber tape, the arc-motion cutter may have difficulty cutting smoothly. This is because the contact method and force conditions between the blade and the tape are relatively complex during cutting. For hard tape materials, blade slippage and incomplete cutting may occur. Summary of the Invention

[0004] This utility model aims to solve one of the technical problems existing in the prior art.

[0005] This application provides a core mechanism for a tape sealing machine, including a side plate and a cutter assembly. The cutter assembly includes a connector, a cutter, and an actuator. The cutter is linearly slidably mounted on the side plate via the connector and has a certain angle with the tape surface. When the packaging box approaches or moves away from the cutter, the actuator, in conjunction with the connector, controls the cutter to retract or extend.

[0006] The cutting blade slides perpendicular to the tape surface, cutting the tape at a 90° angle.

[0007] The actuator is a bent plate, with the middle part rotatably mounted on the side plate via a hinge. One end is the actuating end, which extends out of the side plate and abuts against the outer end of the connector. The other end is the limiting end. A limiting rod is provided on the side plate, which works with the limiting end to limit the range of outward swing of the actuating end.

[0008] The connector includes a lifting plate and a connecting plate. The lifting plate is slidably mounted on the side plate via a slide rail and a slider, and its outer end abuts against the actuator. The connecting plate includes a connecting section and a mounting section that are perpendicularly connected to each other. The connecting section is fixed to the lifting plate by screws, and the cutter is fixed to the outer end of the mounting section by screws.

[0009] Each slider and slide rail is provided in pairs. Each slider has a vertical slide groove and is fixedly mounted on the side plate. Each slide rail is symmetrically fixed on both sides of the lifting plate. Each pair of slide rails is slidably inserted into the vertical slide groove.

[0010] The connector also includes a bracket, which is fixed to the side plate by screws. A sliding rod that can float up and down is mounted on the bracket. A spring is fitted over the sliding rod. One end of the sliding rod is fixed to the connector, and the other end extends out of the bracket.

[0011] The connecting section is provided with a horizontal waist-shaped groove, and the lifting plate is provided with several screw holes.

[0012] The cutter has a pair of symmetrical vertical waist-shaped grooves, and the mounting section has corresponding screw holes.

[0013] A ring is mounted on the top of the connector by screws. The ring is made of flexible material and its peripheral wall slides and rubs against the top and bottom sides of the actuator.

[0014] An extension plate is detachably mounted on the actuator end via screws, and an extension portion extending towards the tool and contacting the circumferential wall of the annulus is provided at the bottom of the actuator end.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The cutter has been changed from the circular motion cutting in the prior art to the straight up and down motion cutting in this application. Compared with the prior art, the cutter of this application can cut the tape at a preset angle, which makes it easier to cut the tape, reduces failures, and improves work efficiency.

[0017] 2. The stability of the cutter's lifting and lowering is improved by setting up a bracket, a slide bar, a pair of slide rails, and a pair of sliders;

[0018] 3. By setting horizontal oblong holes on the connecting section, a pair of vertical oblong holes on the cutter, and several screw holes on the lifting plate and connecting plate respectively, the horizontal position and initial height of the cutter can be adjusted with screws, and the position of the cutter cutting the tape can be adjusted to adapt to different scenarios.

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0026] The following description, in conjunction with the accompanying drawings, details the tape sealing machine mechanism provided in this application through specific embodiments and application scenarios.

[0027] Example 1:

[0028] like Figures 1 to 3 As shown in the figure, this application embodiment provides a tape sealing machine core, including a side plate 1 and a cutter assembly 2. The cutter assembly includes a connector 21, a cutter and an actuator 22. The cutter is linearly slidably mounted on the side plate 1 at a preset angle through the connector. When the packaging box is close to the cutter / away from the cutter, the actuator 22 cooperates with the connector 21 to control the cutter to retract / extend.

[0029] Furthermore, the sliding trajectory of the cutter is perpendicular to the surface of the tape, and the cutter cuts the tape at a 90° angle.

[0030] Furthermore, the actuator 22 is in the shape of a bent plate, and is rotatably mounted on the side plate 1 via a hinge in the middle. One end is the actuating end 221, which extends out of the side plate 1 and abuts against the outer end of the connector 21 on its inner side. The other end is the limiting end 222. The side plate 1 is provided with a limiting rod 23, which works with the limiting end 222 to limit the range of outward swing of the actuating end 221.

[0031] Furthermore, the connector 21 includes a lifting plate 211 and a connecting plate 212. The lifting plate 211 is slidably mounted on the side plate 1 via a sliding pair, and its outer end abuts against the actuator 22. The connecting plate 212 includes a connecting section 2121 and a mounting section 2122 that are perpendicularly connected to each other. The connecting section 2121 is fixed to the lifting plate 211 by screws, and the cutter is fixed to the outer end of the mounting section 2122 by screws.

[0032] Furthermore, each slider 6 and slide rail 7 is provided in pairs. Each slider 6 has a vertical slide groove and is fixed on the side plate 1 respectively. Each slide rail 7 is symmetrically fixed on both sides of the lifting plate 211. Each pair of slide rails 7 is slidably inserted into each vertical slide groove.

[0033] Furthermore, it also includes a bracket 3, which is fixed to the side plate 1 by screws. A sliding rod 4 that can float up and down is installed on the bracket 3. A spring 24 is installed on the sliding rod 4. The upper end is fixed to the connector 21, and the lower end extends to the bottom of the bracket 3 and is provided with a retaining ring 5 on the peripheral wall.

[0034] Furthermore, the outer end of the cutter is a blade with serrations.

[0035] In this embodiment of the application, due to the above-described structure, when the carton passes under the cutter assembly 2, it first contacts the limiting end 222. Through the pushing force, the actuator 22 rotates around the hinge axis, the actuating end 221 lifts up, the limiting end 222 moves away from the limiting rod 23, and the lifted actuating end 221 presses down on the connecting member 21, causing the connecting member 21, the cutter, and a pair of slide rails 7 to slide along the vertical slide groove towards the side plate 1. The spring 24 is compressed, and the retaining ring 5 disengages from the top surface of the bracket 3. When the limiting end 222 disengages from the carton, the spring 24 releases its elastic potential energy, causing the connector 21, the cutter, and a pair of slide rails 7 to slide out of the side plate 1 along the vertical slide groove. The cutter extends out of the side plate 1 to cut the tape. The connector 21, which moves out of the side plate 1, pushes the actuator 22 to rotate around the pin, causing the actuator 221 to extend out of the side plate 1. The limiting end 222 approaches and contacts the outer wall of the limiting rod 23, thus completing one tape cutting action.

[0036] Serrated blades help cut tape because the contact between the serrated blade and the tape is intermittent, resulting in a smaller actual contact area compared to a smooth blade. According to the pressure formula p = F / S (where p is pressure, F is force, and S is the area of ​​contact), under the same applied pressure, a smaller contact area generates greater pressure, making it easier for the blade to cut into the tape.

[0037] Example 2:

[0038] like Figures 1 to 3 As shown, in this embodiment, in addition to the structural features included in the foregoing embodiments,

[0039] Furthermore, the connecting section 2121 is provided with a transverse waist-shaped groove 8, and the lifting plate 211 is provided with several screw holes.

[0040] Furthermore, the cutter is symmetrically provided with a pair of vertical waist-shaped grooves 9, and the mounting section 2122 is provided with corresponding screw holes.

[0041] In this embodiment of the application, due to the above-described structure, the transverse waist-shaped groove 8 on the connecting section 2121 is arranged horizontally. After the screw passes through the transverse waist-shaped groove 8, it is threadedly connected to the screw hole on the lifting plate 211 to fix the connecting section 2121. The pair of vertical waist-shaped grooves 9 on the cutter are arranged vertically. After the screw passes through the vertical waist-shaped grooves 9, it is threadedly connected to the screw hole on the mounting section 2122. Loosening these screws allows the connecting section 2121 to move horizontally, allowing the cutter to move vertically to adjust the height and front-back position of the cutter. After the position adjustment is completed, tightening these screws fixes the position of the cutter, thereby controlling the timing of the cutter's contact with the tape. The higher the initial position of the cutter and / or the farther away from the front tape pressure roller 100, the longer the tape left on the carton when cutting the tape. Conversely, the lower the initial position of the cutter and / or the closer to the front tape pressure roller 100, the shorter the tape left on the carton when cutting the tape.

[0042] Example 3:

[0043] like Figures 1 to 3 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, a ring 10 is installed on the top of the connector 21 by screws. The ring 10 is made of flexible material, and its peripheral wall slides and rubs against the bottom side of the actuator 221.

[0044] Furthermore, an extension plate 11 is detachably mounted on the execution end 221 by screws, and the bottom of the execution end 221 is provided with an extension portion that extends toward the tool and contacts the circumferential wall of the ring 10.

[0045] Furthermore, the extension plate 11 is provided with a pair of parallel waist-shaped grooves 12 parallel to its extension direction, and the execution end 221 is provided with several screw holes. By passing several screws through the pair of parallel waist-shaped grooves 12 and tightening these screws, the extension plate 11 is fixed on the execution end 221.

[0046] In this embodiment of the application, due to the above-described structure, the extension at the bottom of the actuator 221 rubs against the circumferential wall of the annulus 10 when the actuator 221 is raised or lowered. By loosening the screws corresponding to the extension plate 11, the extension plate 11 can extend and retract along the extension direction of the parallel waist-shaped groove 12. The longer / shorter the free end of the actuator 221 extends, the longer / shorter the length of the tape between the carton and the cutter when the carton is separated from the actuator 221. Tightening these screws can fix the extension plate 11.
