Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to an auxiliary device for a manual packing machine. Background Art

[0002] A baler is a cabinet-style device that wraps items with strapping tape. It tightens the strapping tape around the items and securely connects the two ends. Manual balers require manual wrapping of the strapping tape. Products are often packaged for easy storage and transportation, and are therefore widely used across various industries.

[0003] Currently, commonly used balers can only strap items once. However, due to the limited width of the strapping tape, large or loosely stacked items require multiple strapping cycles to ensure a secure package. This requires manual movement of the items to allow the strapping tape to be re-strapped at different locations. In practice, balers are often connected to other equipment via conveyor belts. Manually moving items is time-consuming and labor-intensive, and cannot keep up with the speed of the conveyor belt. This can easily lead to cargo accumulation, reduced packaging efficiency, and ultimately impact the efficiency of the entire production line.

[0004] A search revealed a Chinese invention patent with publication number CN108706114B, which discloses a carton baler for packaging with multiple straps. The device comprises a strapping machine, a conveyor belt, and a carton limiting device. The strapping machine comprises a lower support platform and an upper frame. The conveyor belt is mounted on the support platform and passes through the frame. The carton limiting device comprises a pair of horizontal support plates. The upper end surface of the frame is formed with a pair of front-to-back symmetrical upper support plates. The pair of horizontal support plates slide left and right on the opposite end surfaces of the pair of upper support plates. A pair of central support rods are synchronously rotated between the left portions of the pair of horizontal support plates. Telescopic support rods are respectively provided at both ends of the central support rods for telescopic operation. A limiting roller is pivotally connected between the pair of telescopic support rods on the same side. The device can strap multiple straps to items, but it can only strap in one direction. However, loosely stacked items need to be strapped in multiple directions, and strapping in only one direction will easily cause them to scatter. Utility Model Content

[0027] Example 1

[0028] Refer to the attached Figure 1-6The present application provides a manual baler auxiliary device, comprising a turntable 1 and a base 2 installed on the manual baler. The manual baler adopts the box-type manual baler in the prior art. The strapping reel is pre-installed in the device, and the end of the strapping tape passes upward through the top plate of the baler. The user needs to manually pull the strapping tape around the items to be packaged. When the device is used, the original top plate of the manual baler can be replaced, or the base 2 can be covered on the original top plate. A first through hole is provided in the middle of the base 2 along the length direction. The position of the first through hole should be adapted to the position where the strapping tape passes through the box body, and the width of the first through hole should be larger than the width of a conventional strapping tape. A groove is provided on the top surface of the base 2, and the groove is divided into two symmetrical parts by the first through hole. A driving belt 15 is provided on the side wall of the base 2 in the groove. The driving belt 15 is divided into two symmetrical parts by the first through hole like the groove. There are several turntables 1, and several turntables 1 are evenly arranged in the groove. The bottom edge of the turntable 1 is provided with a drive wheel 3, which is compatible with a drive belt 15. The drive wheel 3 and drive belt 15 are used to drive the turntable 1 to rotate. The rotation direction of the drive wheels 3 installed on different turntables 1 is equal. The number of turntables 1 is preferably four. Each time the four turntables 1 drive an item to rotate 90 degrees, the drive wheel 3 does not need to cross the first through hole. This prevents the drive wheel 3 from getting stuck in the first through hole when the turntable 1 rotates, ensuring smooth rotation of the turntable 1. The turntable 1 is provided with a fixed clamp 4 and a drive assembly. The fixed clamp 4 is used to clamp the items to be packaged. The fixed clamp 4 is rotatably connected to the turntable 1, and a torsion spring 13 is connected between the fixed clamp 4 and the turntable 1. A connecting belt 11 is connected below the fixed clamp 4. The drive assembly drives the fixed clamp 4 to deflect via the connecting belt 11. One end of the torsion spring 13 is fixed to the turntable 1, and the other end is connected to the fixing clamp 4. When the torsion spring 13 is not under force, the end connected to the fixing clamp 4 is parallel to the top surface of the turntable 1 and deflected in the direction of the first through hole. The driving wheel 3 is equipped with a second motor.

[0029] Preferably, the turntable 1 is configured in a sector shape, and the driving wheel 3 is disposed on one side of the arc edge at the bottom of the turntable 1. Corresponding to the turntable 1, the groove is configured in a circular shape, with the arc edge of the turntable 1 contacting the sidewall of the groove, and the driving wheel 3 disposed at the intersection of the arc edge of the turntable 1 and a straight edge. Every time the turntable 1 rotates 90°, two driving wheels 3 will move above the first through hole. Here, half of the driving wheel 2 is disengaged from the driving belt 15 and suspended in the air, while the other half remains engaged with the driving belt 15. That is, the driving wheel 3 does not completely disengage from the driving belt 15. When the turntable 1 rotates another 90° in the opposite direction, the driving wheel 3 can still rotate along the driving belt 15 without idling.

[0030] Preferably, a cavity is defined within the turntable 1, and a drive assembly is disposed within the cavity. The drive assembly includes a motor 7, which is disposed on a sidewall of the cavity. A pulley 8 is connected to the output shaft of the motor 7 via a key. The turntable 1 is also provided with a pulley 9 on the sidewall of the cavity. Pulley 9 is provided below the retaining clamp 4. The same belt 10 is sheathed around pulleys 8 and 9. A reel 12 is provided on the side of pulley 9 proximal to the turntable 1, and a connecting belt 11 is wound around reel 12. When motor 7 drives pulley 8 to rotate, pulley 8 drives pulley 9 to rotate via belt 10. When pulley 9 rotates, reel 12 rotates synchronously with it, and the connecting belt 11 can be wound around or detached from reel 12. When the connecting belt 11 is separated from the reel 12, the fixing clamp 4 is gradually lifted from the turntable 1 and deflected toward the first through hole with the torsion spring 13 as the axis. When the connecting belt 11 is wound around the reel 12, the fixing clamp 4 gradually moves away from the first through hole and deflects toward the turntable 1.

[0031] Preferably, a second through hole is provided on one side of the top of the turntable 1, and the fixing clip 4 is arranged in the second through hole. When the fixing clip 4 deflects to the top surface of the turntable 1, it will fall into the second through hole and be flush with the top surface of the turntable 1.

[0032] Preferably, an ADXL345 gravity sensor is installed at the top of motor 7. Motor 7 and the gravity sensor are connected via an electrical circuit. A button 5 is installed above the gravity sensor, and a spring 6 is installed between button 5 and the gravity sensor. When button 5 is pressed, the pressure is transmitted to the gravity sensor via spring 6. The gravity sensor transmits a signal to the 8051 single-chip microcomputer, which controls motor 7 to start. Motor 7 rotates pulley 8, and at the same time, connecting belt 11 gradually disengages from the reel, causing retaining clip 4 to deflect toward the first through hole.

[0033] Preferably, the top of the button 5 is set to be hemispherical, so that the objects on the turntable can pass over the button 5 more smoothly, and the top of the button 5 can be prevented from being too sharp and causing damage to the objects.

[0034] When used in this application, the manual baler is arranged at the end of the conveyor belt, and the strapping mechanism, motor one, and the start and shut down of motor two of the manual baler are all controlled by the 8051 single-chip microcomputer.

[0035] Working principle: When the items to be packaged are transferred from the conveyor belt to the turntable, the items are pressed onto the button 5, and the fixing clips 4 on both sides of the first through hole are lifted from the turntable 1 and deflected toward the first through hole to clamp the items to be packaged. The user manually pulls the strapping tape around the items, and the strapping mechanism of the manual strapping machine straps the items once. The strapping function of the strapping mechanism is completed, and the motor 2 is started. The four turntables 1 drive the items to rotate 90°. After the rotation is completed, the user pulls the strapping tape around the items again, and the strapping mechanism of the manual strapping machine straps the items again. At this point, the packaging work of one item is completed, and the motor 1 7 rotates in the opposite direction, and the fixing clip 4 deflects away from the first through hole. The fixing clip releases the items that have been packaged, and the unpackaged items on the conveyor belt continue to be transported to the turntable, and the packaged items on the turntable are pushed out of the turntable to start the next round of packaging.

[0036] Example 2

[0037] Refer to the attached Figure 7 The present application provides a manual baler auxiliary device. Compared with Example 1, in order to make the turntable 1 rotate more smoothly, a roller 14 is provided at the bottom of the turntable 1, and an annular slide groove is provided on the bottom surface of the base 2 within the installation area. The position and width of the slide groove are adapted to the position and width of the roller 14, and the rotation direction of the roller 14 is tangent to the slide groove.

[0038] Working principle: When the driving wheel 3 drives the turntable 1 to rotate, the roller 14 can assist the driving wheel 3 to drive the roller 14 to rotate under the action of inertia. The roller 14 can also support the turntable 1 to reduce the friction between the bottom of the turntable 1 and the base 2, making the turntable 1 rotate smoother.
