Description

Technical Field

[0001] The invention relates to the field of packaging equipment, and in particular to a full-automatic packaging device. Background Art

[0002] In a product production line, usually the last step is to pack the processed or packaged products for easy transportation and storage. Initially, the packing process was done manually, that is, the strapping tape was put on the carton, iron rollers were strung on both ends of the strapping tape, the strapping tape was tightened manually, the rollers were clamped, and then the excess strapping tape was cut off. This method is cumbersome to operate, has low efficiency, and high labor intensity. Therefore, a baler has appeared in the prior art. The baler is a machine that wraps the product or packaging box with the strapping tape, tightens it, and melts the two ends through thermal effect or connects them with buckles and other materials, so that the strapping tape can be tightly attached to the surface of the strapped product or packaging box. The baler is highly efficient, does not require manual processing, and has a high degree of automation. It is the future trend of baling processing on the packaging production line.

[0027] The pre-feed belt mechanism is arranged between the strapping belt 201 storage area 101 and the belt feeding area 102. The pre-feed belt mechanism includes a pre-feed belt motor 3 and a pre-feed belt pulley group 4. The pre-feed belt pulley group 4 includes a pre-feed belt driving wheel 401 and a pre-feed belt driven wheel 402 that match each other. The pre-feed belt motor 3 is connected to the pre-feed belt driving wheel 401.

[0028] In a specific implementation of the present invention, a packaging box 10 placement platform 106 is provided on the frame 1, which is convenient for bundling and packing the packaging box 10, and is also convenient for loading and unloading; a control device is provided on the platform 106, and an execution command in the bundling process is issued by the control device, which is convenient for remote operation; a strapping belt 201 storage area 101 and a strap feeding area 102 are provided below the platform 106, wherein the strapping belt 201 is installed in the strapping belt 201 storage area 101 by means of a tape reel 2, and the strapping belt 201 is transferred from the strapping belt 201 storage area 101 to the strap feeding area 102 to complete the strap feeding, strap withdrawal and strapping processes. In order to prevent the strapping belt 201 from being entangled on the platform 106 during the strapping process, a groove 104 for accommodating the strapping belt 201 is provided in the middle of the platform 106, and a cutting device 105 is provided below the groove 104; it also includes a strap feeding and retreating mechanism 5 and a pre-feeding mechanism.

[0029] In the specific use of the pre-feed belt mechanism, the strapping belt 201 is sent out from the belt reel 2 in the strapping belt 201 storage area 101, passes through the pre-feed belt mechanism, and reaches the advance and retreat belt mechanism 5 in the belt feeding area 102. Since the pre-feed belt mechanism includes a pre-feed belt motor 3 and a pre-feed belt pulley group 4, the pre-feed belt pulley group 4 includes a pre-feed belt driving wheel 401 and a pre-feed belt driven wheel 402 that match each other, the pre-feed belt motor 3 is connected to the pre-feed belt driving wheel 401, and the strapping belt 201 is arranged between the pre-feed belt driving wheel 401 and the pre-feed belt driven wheel 402. After power is turned on, the pre-feed belt motor 3 rotates, driving the driving wheel to rotate. After the strapping tape 201 is transported from the strapping tape 201 storage area 101 to the strap feeding area 102, when a certain amount of strapping tape 201 remains in the strap feeding area 102, the pre-feeding motor 3 stops running, and then stops feeding the strapping tape to the strap feeding area 102, so that the strapping tape 201 sent out by the turntable due to inertia stays in the strapping tape 201 storage area 101, ensuring that the amount of strapping tape 201 remaining in the strap feeding area is limited, avoiding chaotic entanglement of the strapping tape 201 in the strap feeding area 102, solving the problem of the equipment not being able to operate normally due to too much strapping in the strap feeding area 102, and improving the use efficiency of the baling machine. In addition, if the pre-feed belt motor 3 reverses, it drives the pre-feed belt driving wheel 401 to reverse, and returns the excess strapping belt 201 in the strapping area 102 to the strapping belt 201 storage area 101, further avoiding the occurrence of chaotic entanglement of the strapping belt 201 due to excessive strapping belt 201 in the strapping area 102; especially after the strapping belt in the storage area 101 is used up, it is convenient to take out the excess strapping belt in the strapping area 102.

[0030] The belt advance and retreat mechanism 5 is installed on the frame 1 of the baler, wherein the base adopts a plate-shaped structure and is fixedly installed on the frame 1. A belt advance wheel group and a belt retreat wheel group are arranged on the base, wherein the belt advance wheel group and the belt retreat wheel group are arranged up and down, the belt advance wheel group includes a belt advance driving wheel 501 and a belt advance driven wheel 502 that match each other, and the belt retreat wheel group includes a belt retreat driving wheel 505 and a belt retreat driven wheel 506 that match each other. After the pre-feeding mechanism sends the strapping belt 201 to the belt advance and retreat mechanism 5, the strapping belt 201 enters from the gap between the belt advance driving wheel 501 and the belt advance driven wheel 502, and is retracted from the belt retreat The gap between the driving wheel 505 and the belt-retracting driven wheel 506 is derived; the belt-advancing and belt-retracting motor and the strapping motor are both mounted on the baler frame 1, and the output end of the belt-advancing and belt-retracting motor is connected to the belt-advancing driving wheel 501 and the belt-retracting driving wheel 505 through the conveyor belt; since the belt-advancing wheel group and the belt-retracting wheel group are arranged up and down, when the same conveyor belt is used, the belt-advancing driving wheel 501 and the belt-retracting driving wheel 505 have the same direction of rotation, so they guide the strapping belt 201 to move in the same direction, but since they are arranged up and down, there is no need to change the direction of rotation of the belt-advancing and belt-retracting motor, and the strapping belt 201 can realize the belt-advancing and belt-retracting functions;

[0031] When the strapping machine is in operation, the control device controls the belt-retracting driven wheel 506 to enlarge the gap between the belt-retracting driven wheel 506 and the belt-retracting active wheel 505, and the control device controls the belt-in driven wheel 502 to reduce the gap between the belt-in driving wheel 501 and the belt-in driven wheel 502, thereby driving the strapping belt 201 to enter; when the strapping machine is in operation, the control device controls the belt-in driven wheel 502 to enlarge the gap between the belt-in driven wheel 502 and the belt-in driving wheel 501, and the control device controls the belt-retracting driven wheel 506 to reduce the gap between the belt-retracting active wheel 505 and the belt-retracting driven wheel 506, thereby driving the strapping belt 201 to withdraw through the friction between the belt-retracting active wheel 505 and the belt-retracting driven wheel 506; thereby ensuring that the motor rotates in one direction during the use of the strapping machine, thereby increasing the service life of the motor, thereby reducing the use cost of the strapping machine and solving the problem of high use cost of the strapping machine;

[0032] In this embodiment, the working process of the cutting device 105 can refer to the patent previously applied for by the applicant, and its authorization announcement number is CN 202508295 U, so it is not described in detail in this document.

[0033] Furthermore, in order to reduce the damage to the strapping belt 201 during the strapping process, the present invention also includes a swinging mechanism, which includes a cover plate 6 arranged above the groove 104, and one end of the cover plate 6 is hinged to the side wall of the groove 104; it also includes a connecting rod 8, a swing rod 9 and a driving unit; the driving part is fixedly arranged on the frame 1, and the swing rod 9 is rotatably connected to the frame 1, wherein one end of the swing rod 9 is connected to the driving part, and the other end of the swing rod 9 is hinged to the connecting rod 8, and the other end of the connecting rod 8 is connected to the cover plate 6. In specific use, the strapping belt 201 is sent into the groove 104 through the advance and retreat belt mechanism 5, and the cover plate 6 is composed of a horizontal plate and a vertical plate to form a bent structure, wherein the horizontal plate matches the opening of the groove 104, and the bottom of the vertical plate is hinged to the side wall of the groove 104. When the strap is advanced, the cover plate 6 is closed to cover the groove 104; the cover plate 6 is connected to the swing rod 9 through the connecting rod 8; when the strap is withdrawn, the driving unit starts to run, wherein the driving unit can be driven by manpower or other automatic machinery, the driving unit drives the swing rod 9 to swing, and the swing rod 9 drives the connecting rod 8 to move. Since one end of the cover plate 6 is hinged to the side wall of the groove 104, the connecting rod 8 drives the cover plate 6 to rotate when it moves, exposing the groove 104, so that the strapping belt 201 can move freely during the withdrawal process, thereby solving the problem of friction between the existing strapping belt 201 and the groove 104 cover plate 6 during the withdrawal process, avoiding wear of the strapping belt 201 during the withdrawal process, and improving the service life of the strapping belt 201.

[0034] Furthermore, in order to allow the strapping strap 201 outside the packaging box 10 to reach a predetermined strapping force after strapping, the present invention further provides a strapping wheel group and a strapping motor on the base, wherein the strapping wheel group is arranged on the side of the belt feed wheel group, and the strapping wheel group includes a strapping driving wheel 503 and a strapping driven wheel 504 that match each other. In specific use, the strapping strap 201 enters from the gap between the belt feed driving wheel 501 and the belt feed driven wheel 502, passes through the gap between the strapping driving wheel 503 and the strapping driven wheel 504, and then is led out from the gap between the belt withdrawal driving wheel 505 and the belt withdrawal driven wheel 506; during the strapping process, the strap is first withdrawn, and the control device controls the belt withdrawal driven wheel 506 and the belt feed driven wheel 502, so that the gap between the belt withdrawal driven wheel 506 and the belt withdrawal driving wheel 505 is reduced, and the gap between the belt feed driving wheel 501 and the belt feed driven wheel 502 is reduced. The gap is enlarged, and the belt-retracting active wheel 505 cooperates with the belt-retracting driven wheel 506 to drive the strapping belt 201 to be withdrawn. After the belt is withdrawn, the packaging box 10 is then strapped. The control device controls the belt-retracting driven wheel 506 and the belt-feeding driven wheel 502, so that the gap between the belt-retracting driven wheel 506 and the belt-retracting active wheel 505 is enlarged, and the gap between the belt-feeding active wheel 501 and the belt-feeding driven wheel 502 is also enlarged. At the same time, the control device controls the strapping driven wheel 504, so that the gap between the strapping driven wheel 504 and the strapping active wheel 503 becomes smaller, and the friction force between the strapping active wheel 503 and the strapping driven wheel 504 is used to drive the carton to be tightened. The control device controls the length of time that the strapping active wheel 503 and the strapping driven wheel 504 are in contact with each other, and then the tightening force is controlled, so that the strapping belt 201 outside the packaging box 10 after strapping reaches a predetermined strapping force.

[0035] Furthermore, in order to accurately control the switching time between unbundling and bundling during the bundling process, the present invention further includes a proximity switch sensor, wherein the proximity switch sensor is arranged on the substrate and is located on the side of the unbundling driven wheel 506; one end of the proximity switch sensor is connected to the unbundling driven wheel 506, and the other end is electrically connected to the control device. In the beginning of unbundling, the bundling belt 201 is subject to less resistance, and at this time, the friction between the unbundling driving wheel 505 and the unbundling driven wheel 506 is small. When the unbundling ends and enters the bundling stage, the bundling belt 201 is blocked by the bundled object. , resulting in greater friction between the unwinding active wheel 505 and the unwinding driven wheel 506. The proximity switch sensor checks the stress borne by the unwinding driven wheel 506 and transmits it to the control device, which is compared with a threshold value preset in the control device. When the stress value is greater than the preset threshold value, the control device controls the unwinding driven wheel 506 to increase the gap between the unwinding driven wheel 506 and the unwinding active wheel 505. At the same time, the control device controls the tying driven wheel 504 to reduce the gap between the tying driven wheel 504 and the tying active wheel 503, thereby completing the tightening of the tied object.

[0036] Furthermore, in order to facilitate the adjustment of the gap between the belt-feeding driven wheel 502 and the belt-feeding driving wheel 501, the gap between the belt-retracting driven wheel 506 and the belt-retracting driving wheel 505, and the gap between the tying driven wheel 504 and the tying driving wheel 503, in the present invention, the belt-feeding driven wheel 502, the belt-retracting driven wheel 506 and the tying driven wheel 504 are all eccentric wheel structures, and the eccentric wheel structure includes an eccentric shaft and a round roller sleeved outside the eccentric shaft.
