Description

Technical Field

[0001] This utility model belongs to the field of packing strap cutting, specifically involving automatic cutting of packing straps through automatic control. Background Technology

[0002] Packing straps are a type of composite material widely used for bundling boxes. They are typically made of materials such as polypropylene (PP), polyester (PET), paper tape, and nylon tape, and are commonly used in logistics, warehousing, manufacturing, electronics, and carton packaging. When using them, the packing straps need to be disassembled, specifically involving the disassembly and assembly of semi-finished products, and the disassembly and assembly of tea and tobacco reprocessing. Therefore, the cutting process of the packing straps is particularly important. In assembly line applications, the speed of disassembly affects work efficiency. Existing packing strap cutting equipment cannot cut the packing straps in different positions or cannot insert the packing straps between the cutters for cutting, which to some extent affects the success rate of cutting.

[0003] Current tape cutting equipment, such as the Chinese patent CN 214084926 U which proposes a cutting structure and a packing machine with a cutting structure, first inserts the packing tape into the equipment, and then drives the cutter to reciprocate through the crankshaft, thereby cutting the packing tape; however, when the gap between the packing tape and the box is small, the equipment cannot be inserted between the two, so it cannot perform the cutting task. The cutter must be manually adjusted according to the position information of the packing tape, which greatly reduces its automation level and has poor cutting feasibility.

[0004] Therefore, this invention addresses the aforementioned problems by proposing a multi-degree-of-freedom intelligent strapping cutting device for box-shaped packaging. This device can efficiently perform strapping cutting tasks, adapt to various cutting environments, possesses good feasibility and a high cutting success rate, and can be applied to various strapping cutting assembly line operations. Summary of the Invention

[0005] The purpose of this invention is to design a multi-degree-of-freedom intelligent tape cutting device for box packing straps to address the above-mentioned problems.

[0006] The technical solution adopted in this utility model patent is as follows:

[0007] A multi-degree-of-freedom intelligent strapping cutting device for box packing straps, characterized in that: the device includes at least a power component, a support component, a detection component, a strapping pressing component, a strapping cutting component, and auxiliary devices;

[0008] The power component includes two motors: a first motor and a second motor. The support component includes at least a fixed bracket, a rotating bracket, and a frame. The first motor is fixedly mounted on the fixed bracket of the support component, and the rotor of the first motor is connected to the rotating bracket of the support component. The second motor is fixedly mounted on the reducer of the auxiliary device. The reducer is fixedly mounted on the rotating bracket, and the rotor of the reducer is connected to the frame of the support component. The first motor drives the rotating bracket to rotate, and the second motor drives the frame to rotate.

[0009] The rotating bracket of the supporting component is fixedly equipped with detection plate one and detection plate two. Detection plate one is fixedly installed at the top of the rotating bracket, and detection plate two is fixedly installed at the bottom of the rotating bracket near the reducer.

[0010] The angle sensor of the detection component includes angle sensor one and angle sensor two. Angle sensor one is fixedly installed on the fixed bracket of the support component. The detection plate one of the rotating bracket moves in the gap between angle sensors one. Angle sensor one is used to limit the rotation angle of the rotating bracket along the vertical plane of the axis of motor one and control its rotation angle to not exceed 60°. Angle sensor two is fixedly installed on the frame of the support component. The detection plate two of the rotating bracket moves in the gap between angle sensors two. Angle sensor two is used to limit the rotation angle of the frame along the vertical plane of the axis of motor two and control its rotation angle to not exceed 60°.

[0011] The angle sensor of the detection component includes at least three detection heads, namely detection head a, detection head b and detection head c. Detection head a and detection head c are located on the left and right sides of detection head b and are on the same plane. The axes of detection head a and detection head c form certain angles with the axis of detection head b, namely θ1 and θ2. The detection piece moves between detection head a and detection head c. When detection head a and detection head c detect the detection piece, they will stop rotating.

[0012] The tape cutting component includes at least a tape cutting cylinder, a cutter holder, and a cutter; the tape cutting cylinder of the tape cutting component is fixedly mounted on the frame, and the cutter of the tape cutting component is connected to the tape cutting cylinder through the cutter holder. The cutter consists of two symmetrical blades and can perform tape cutting tasks from both sides of the packing tape; the cutter, driven by the tape cutting cylinder, passes through the guide groove of the guide seat of the auxiliary device to perform tape cutting tasks.

[0013] The pressing component includes at least a pressing cylinder, a connecting frame, and a pressing block; the pressing cylinder of the pressing component is fixedly mounted on the frame, and the pressing block of the pressing component is connected to the pressing cylinder through the connecting frame. The pressing block consists of two symmetrical blocks, and the pressing block passes through the guide groove of the guide seat of the auxiliary device to fix the packing strap under the drive of the pressing cylinder.

[0014] The auxiliary device has a strap-lifting head fixedly installed at the bottom of the guide seat. The strap-lifting head has two grooves in the middle. The strap-lifting head lifts up the packing strap, and the packing strap enters the groove along the upper surface of the strap-lifting head. A position sensor is installed on the side of the strap-lifting head near the pressing block to detect whether the packing strap has entered the groove.

[0015] When the position sensor of the detection component detects that the packing strap has entered the groove, the pressing cylinder drives the pressing block to press the packing strap downward, and then the cutting cylinder drives the cutter to cut the packing strap.

[0016] The first motor controls the horizontal rotation angle of the frame. The cutter and clamping block rotate synchronously with the frame to keep the picking head groove and the packing strap parallel. The first sensor of the detection component will command the frame to stop rotating if it detects that the frame rotation angle exceeds the maximum limit angle. The second motor controls the rotation angle of the frame. The second motor controls the frame to rotate a certain angle, and the picking head is inserted under the packing strap to enter the groove. The position sensor detects the packing strap, and the second motor drives the frame to straighten and start the tape cutting task.

[0017] The first motor rotates according to the degree of inclination of the packing strap, so that the frame and its cutter are perpendicular to the packing strap, ensuring that the packing strap can smoothly enter the groove; the second motor rotates during operation, so that the picking head is at a certain angle to the horizontal position, making it easier for the picking head to be inserted between the packing strap and the box, avoiding the failure of cutting the strap due to the packing strap and the box being too close together.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This utility model proposes an innovative rotating bracket with horizontal rotation function. When the packing strap is tied to the box at an angle, the bracket can adaptively rotate according to the tilt angle of the packing strap, ensuring that the cutter always remains perpendicular to the packing strap, thereby significantly improving the success rate of cutting the strap.

[0020] 2. This utility model also features a rotatable frame specifically designed to address the problem of difficulty in inserting the cutter when the packing strap is tightly fitted to the box. By vertically rotating the frame, in conjunction with the strapping head, the packing strap can be smoothly lifted to the ideal position where the cutter can cut, thus ensuring a smooth cutting process.

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] Example:

[0030] Please refer to Figures 1 to 6 The present invention relates to a multi-degree-of-freedom intelligent tape cutting device for box packing straps, characterized in that: the device includes at least a power component, a support component, a detection component, a tape pressing component, a tape cutting component, and auxiliary devices;

[0031] The power component includes at least two motors; the support component includes at least a fixed bracket (201), a rotating bracket (301), and a frame (1101); the detection component includes at least two angle sensors and one position sensor (801); the cutting component includes at least a cutting cylinder (601), a cutter holder (602), and a cutter (603); the pressing component includes at least a pressing cylinder (701), a connecting frame (702), and a pressing block (703); the auxiliary device includes at least a reducer (103), a guide seat (1001), and a picking head (901).

[0032] Specifically, the motor of the power component includes motor one (101) and motor two (102). Motor one (101) is fixedly installed above the fixed bracket (201) of the support component, and the rotor of motor one (101) is connected to the rotating bracket (301) of the support component. Motor two (102) is fixedly installed on the reducer (103) of the auxiliary device. The reducer (103) is fixedly installed on the rotating bracket (301), and the rotor of the reducer (103) is connected to the frame (1101) of the support component.

[0033] When in use, motor one (101) rotates at a certain angle according to the position of the packing strap to ensure that the cutter (603) and the packing strap are in a vertical position. Motor two (102) drives the frame (1101) to rotate at a certain angle through the reducer (103) so that the frame (1101) and the packing strap are at an acute angle, which makes it easy for the picking head (901) to be inserted between the packing strap and the box.

[0034] Specifically, the rotating bracket (301) is equipped with a detection plate one (302) and a detection plate two (303) that move synchronously with the rotating bracket (301).

[0035] Preferably, the angle sensor of the detection component includes angle sensor one (401) and angle sensor two (501). The angle sensor one (401) is fixedly installed on the fixed bracket (201) of the support component. The detection plate one (302) of the rotating bracket (301) moves in the gap between the angle sensors one (401). The angle sensor one (401) is used to limit the rotation angle of the rotating bracket (301) along the vertical plane of the axis of motor one (101) and control its rotation angle to not exceed 60°. The angle sensor two (501) is fixedly installed on the frame (1101) of the support component. The detection plate two (303) of the rotating bracket (301) moves in the gap between the angle sensors two (501). The angle sensor two (501) is used to limit the rotation angle of the frame (1101) along the vertical plane of the axis of motor two (102) and control its rotation angle to not exceed 60°.

[0036] Specifically, the angle sensor 1 (401) of the detection component includes at least three detection heads, namely detection head a (402), detection head b (403) and detection head c (404). Detection head a (402) and detection head c (404) are located on the left and right sides of detection head b (403) and are on the same plane. The axes of detection head a (402) and detection head c (404) are at certain angles θ1 and θ2 with the axis of detection head b (403) and the angles are equal. Detection piece 1 (302) moves between detection head a (402) and detection head c (404). When detection head a (402) and detection head c (404) detect detection piece 1 (302), they will stop rotating.

[0037] In use, angle sensor one (401) is used to detect the angle through which the rotating bracket (301) has rotated, so as to prevent the rotating bracket (301) from rotating too much. When the rotating bracket (301) exceeds the angle detected by angle sensor one (401), it will stop rotating. Angle sensor two (501) is used to detect the angle through which the frame (1101) has rotated, so as to prevent the frame (1101) from rotating too much. When the rotating frame (1101) exceeds the angle detected by angle sensor two (501), it will stop rotating.

[0038] Specifically, the pressing cylinder (701) of the pressing component is fixedly installed on the frame (1101), and the pressing block (703) of the pressing component is connected to the pressing cylinder (701) through the connecting frame (702). The pressing block (703) is composed of two symmetrical blocks. Under the drive of the pressing cylinder (701), the pressing block (703) passes through the guide groove of the guide seat (1001) of the auxiliary device to fix the packing strap.

[0039] When in use, the position sensor (801) detects that the packing strap has entered the groove of the picking head (901), and the cutting cylinder (601) of the cutting mechanism will press down, driving the pressing block (703) to press the packing strap tightly, so as to prevent the packing strap from falling off during the cutting process.

[0040] Specifically, the cutting cylinder (601) of the cutting component is fixedly mounted on the frame (1101), and the cutter (603) of the cutting component is connected to the cutting cylinder (601) through the cutter holder (602). The cutter (603) consists of two symmetrical blades and can perform the cutting task from both sides of the packing strap. The cutter (603) performs the cutting task by passing through the guide groove of the guide seat (1001) of the auxiliary device under the drive of the cutting cylinder (601).

[0041] When in use, after the pressing mechanism tightens the strapping, the cutting cylinder (601) will drive the cutter (602) to move downwards to cut the strapping.

[0042] Specifically, the strapping head (901) of the auxiliary device is fixedly installed at the bottom of the guide seat (1001). The strapping head (901) has two grooves (902) in the middle. The strapping head (901) lifts up the packing strap, and the packing strap enters the groove (902) along the upper surface of the strapping head (901). A position sensor (801) is installed on the side of the strapping head (901) near the pressing block (703) to detect whether the packing strap has entered the groove.

[0043] Preferably, since the second motor (102) drives the frame (1101) to rotate through a certain angle through the reducer (103), the picking head (901) is fixed on the frame and will be at a certain angle with the box. One corner of the picking head (901) can smoothly penetrate between the packing strap and the box, ensuring that the packing strap can smoothly enter the groove (902) in the middle of the picking head (901).

[0044] When in use, the picker head (901) moves toward the packing strap and inserts the packing strap into the groove of the picker head (901). At this time, the position sensor (801) detects that the packing strap has entered the groove (902) and will start to drive the pressing mechanism to move.

[0045] During operation, motor 1 (101) controls the rotating bracket (301) to rotate at a certain angle according to the bundling angle of the strapping and the box, and the angle sensor 1 (401) detects the rotation angle of the rotating bracket (301) so that the cutting surface of the cutter (603) is perpendicular to the strapping; then motor 2 (102) drives the frame (1101) to rotate and the angle sensor 2 (501) detects the rotation angle of the frame (1101), thereby driving the strap picking head (901) to rotate; the strap picking head (901) begins to insert between the strapping and the box and lifts the strapping smoothly into the groove (902); after the position sensor (801) detects the position information of the strapping, the strap pressing cylinder (701) drives the pressing block (703) to press the strapping; then the strap cutting cylinder (601) drives the cutter (603) to cut the strapping in real time.

[0046] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
