Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to an automatic bagging machine for speaker packaging. Background Technology

[0002] With the continuous improvement of automation levels in modern industrial production, automated packaging equipment has been widely used in various industries, especially in the consumer electronics sector, such as speaker packaging. Automated packaging equipment can significantly improve production efficiency, reduce labor costs, and ensure consistent packaging quality.

[0003] Automatic bagging machines for speaker packaging are a common type of automated equipment. They typically utilize pneumatic actuators such as negative pressure suction cups to perform actions like gripping and opening packaging bags. Therefore, a stable and reliable air supply is fundamental to ensuring the normal operation of the entire machine. In practical applications, these pneumatic actuators need to be connected to the main air source or negative pressure system via pipelines. To facilitate equipment installation, commissioning, and routine maintenance, the pipeline connections usually need to be quick-connect and disconnectable.

[0004] Currently, common connection methods include threaded connectors or simple push-in quick-connect couplings. However, while threaded connectors offer a secure connection, the assembly and disassembly process requires tools, making it cumbersome, inefficient, and unsuitable for the fast-paced, high-efficiency maintenance demands of modern production. Traditional push-in quick-connect couplings, while convenient to assemble and disassemble, pose a risk of insufficient connection and accidental detachment in the high-frequency, continuous vibration environments of automated equipment, or when subjected to accidental pulling in complex wiring. Once detached, this can lead to air supply interruptions, equipment shutdowns, and disruptions to production continuity and stability.

[0005] Therefore, this utility model proposes a quick take-off mechanism for an automatic bagging machine for speaker packaging to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an automatic bagging machine for speaker packaging, which aims to improve the problems of cumbersome operation of pneumatic pipeline connectors in the prior art and the risk of accidental detachment during high-frequency operation of automated equipment.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an automatic bagging machine for speaker packaging, comprising: a connecting pipe, a connector, a rotating shell, a locking bead, a fixing plate, and a spring, wherein the inner wall of the rotating shell has a pressing surface and an unlocking groove communicating with the pressing surface; The connecting tube has a through hole on its wall for the radial movement of the retaining bead. The outer peripheral wall of the connector has a locking groove. The connector is pluggably fitted into the connecting tube.

The spring is sleeved on the outer wall of the connecting tube and its two ends abut against the fixing plate and the rotating shell, respectively. Through the elastic force of the spring, the rotating shell is pushed to the locking position. In the locking position, the pressing surface of the rotating shell presses against the retaining bead, so that the retaining bead is engaged in the locking groove of the connector. When the rotating shell is rotated to the unlocking position, the unlocking groove is aligned with the retaining bead to allow the retaining bead to retract radially.

[0008] Preferably, the quick-connect fitting mechanism further includes a sealing ring, which is disposed around the outer peripheral wall of the connector and provides an airtight seal when the connector is inserted into the connecting pipe.

[0009] Preferably, it includes the aforementioned quick-connection mechanism and a negative pressure lifting suction cup, wherein the connecting pipe of the quick-connection mechanism is connected to the air passage of the negative pressure lifting suction cup.

[0010] Preferably, the automatic speaker packaging bagging machine further includes a first conveyor belt, and the negative pressure lifting suction cup is disposed above the conveying path of the first conveyor belt for adsorbing and opening the packaging bag conveyed by the first conveyor belt.

[0011] Preferably, the automatic speaker packaging machine further includes a second conveyor belt and a pusher. The second conveyor belt is used to transport the speaker product, and the pusher is used to push the speaker product from the second conveyor belt into the packaging bag opened by the negative pressure lifting suction cup.

[0012] Preferably, the automatic bagging machine for speaker packaging further includes a support frame and an adjustable bag-supporting mechanism mounted on the support frame.

[0013] Preferably, the adjustable bag support mechanism includes an extension plate, a support rod fixed to the extension plate, and a hydraulic mover for driving the extension plate to move.

[0016] Preferably, the adjustable bag support mechanism further includes a scale fixed to the extension plate for indicating the spacing between the support rods.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problems of cumbersome connection operation and poor connection reliability of existing pneumatic connectors by setting a quick-connect mechanism consisting of a rotatable rotating shell, spring, locking ball and unlocking groove. It achieves the effect of quick insertion and removal by hand, stable connection and effective prevention of accidental disconnection.

[0018] 2. This utility model solves the problem that existing bag-supporting mechanisms have fixed bag-supporting widths, cannot be compatible with different sizes of packaging bags, and result in poor equipment applicability by setting a spacing adjustment mechanism composed of a bidirectional threaded rod and a threaded block that cooperates with it to control the spacing of the support rods. It achieves the effect of being able to quickly and symmetrically adjust the bag-supporting width, flexibly adapt to the packaging needs of products of different sizes, and improve the versatility of the equipment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-5 This utility model provides an embodiment of an automatic speaker packaging bagging machine, comprising a support 2, a first conveyor belt 1, a second conveyor belt 6, a negative pressure lifting suction cup 4, an adjustable bag-supporting mechanism 3, a pusher 8, and a quick-connection mechanism 9. The first conveyor belt 1 is used to transport packaging bags 5, the second conveyor belt 6 is used to transport speaker products 7, the negative pressure lifting suction cup 4 is disposed above the conveying path of the first conveyor belt 1, the pusher 8 is used to push the speaker products 7 into the packaging bags 5, the adjustable bag-supporting mechanism 3 is mounted on the support 2, and the quick-connection mechanism 9 is used to connect the negative pressure lifting suction cup 4 to a negative pressure source. The quick-connect mechanism 9 includes a connecting pipe 901, a connector 908, a rotating housing 902, a locking ball 905, a fixing plate 906, and a spring 907. The connecting pipe 901 has a tubular end, and a through hole for the locking ball 905 to move radially is formed on the wall of the tubular end. A locking groove is formed on the outer peripheral wall of the connector 908, and the connector 908 is pluggably fitted into the tubular end of the connecting pipe 901. The rotating housing 902 is rotatably and axially movable and fitted onto the outer wall of the connecting pipe 901. The fixing plate 906 is fixedly connected to the outer wall of the connecting pipe 901. The spring 907 is fitted onto the outer wall of the connecting pipe 901, and the two ends of the spring 907 abut against the fixing plate 906 and the rotating housing 902, respectively. The locking ball 905... 05 is accommodated in the through hole of the connecting pipe 901. The inner wall of the rotating shell 902 has a pressing surface and an unlocking groove 903 communicating with the pressing surface. The rotating shell 902 is in the locked position under the elastic force of the spring 907. In the locked position, the pressing surface of the rotating shell 902 is aligned with and radially presses against the retaining bead 905, so that the retaining bead 905 is partially inserted into the locking groove of the connector 908. When the rotating shell 902 is rotated to the unlocked position, the unlocking groove 903 is aligned with the retaining bead 905, so that the retaining bead 905 is radially retracted into the unlocking groove 903. This realizes the mechanism that can only be unlocked at a specific rotation angle, effectively preventing the connector 908 from falling off due to vibration or accidental pulling, and at the same time realizing quick insertion and removal by hand. To ensure airtightness, the quick-connect fitting mechanism 9 also includes a sealing ring 904, which is arranged around the outer peripheral wall of the connector 908 and provides an airtight seal when the connector 908 is inserted into the connecting pipe 901. The overall structure of the adjustable bag support mechanism 3 includes an extension plate 302, a support rod 303 fixed to the extension plate 302, and a hydraulic mover 301 for driving the extension plate 302 to move. The hydraulic mover 301 is fixedly installed on the bracket 2. The output end of the hydraulic mover 301 is fixedly connected to the extension plate 302. By controlling the extension and retraction of the hydraulic mover 301, the extension plate 302 can be driven to reciprocate along a predetermined trajectory, thereby driving the support rod 303 fixed at the end of the extension plate 302 to simultaneously extend into or out of the packaging bag 5. To accommodate packaging bags 5 of different sizes, the spacing between the two support rods 303 is adjustable. The specific adjustment structure is mounted on the extension plate 302. This adjustment structure includes a threaded rod 306, a threaded block 305 threadedly connected to the threaded rod 306, a rotating head 304 for driving the threaded rod 306 to rotate, and a fixing piece 308 for axially limiting the threaded rod 306. The threaded rod 306 has two sections of threads with opposite directions of rotation. The two threaded blocks 305 are respectively threaded onto the two sections of threads on the threaded rod 306. Each support rod 303 is... The threaded rod 306 is rotatably mounted on the extension plate 302 by the fixing plate 308 and the threaded block 305. When the rotating head 304 is rotated using a tool, the rotating head 304 drives the threaded rod 306 to rotate. Due to the limiting effect of the fixing plate 308, the threaded rod 306 only rotates and does not move axially. Then, through the thread transmission, the two threaded blocks 305 are driven to move towards or away from each other along the axial direction of the threaded rod 306, ensuring that the two support rods 303 can open or close synchronously with the center as the reference, and realizing the precise adjustment of the spacing. To facilitate operators in intuitively understanding and setting the spacing of the support rods 303, the adjustable support mechanism 3 also includes a scale 307. The scale 307 is fixed on the extension plate 302 and cooperates with one of the threaded blocks 305 or its indicator mark. When the threaded block 305 moves, the operator can read the scale value on the scale 307 to accurately know the current distance between the two support rods 303, thereby quickly adapting to different specifications of speaker products 7. First, the first conveyor belt 1 transports the flat packaging bag 5 to the bottom of the negative pressure lifting suction cup 4 and positions it. Then, the negative pressure lifting suction cup 4 descends and starts the negative pressure system, adsorbs the upper surface of the packaging bag 5 and lifts it upward, initially opening the bag opening of the packaging bag 5. Next, the hydraulic mover 301 drives the extension plate 302 and the support rod 303 to extend. The support rod 303 extends from the outside into the initially opened packaging bag 5, fully opening the bag opening through a preset interval and keeping it stable. At the same time, the second conveyor belt 6 transports the speaker product 7 to the predetermined work station. The pusher 8 is activated, pushing the speaker product 7 horizontally from the second conveyor belt 6 into the packaging bag 5 that has been opened by the support rod 303, completing the bagging action. The hydraulic mover 301 drives the support rod 303 to exit from the packaging bag 5, the negative pressure lifting suction cup 4 releases the packaging bag 5, and the first conveyor belt 1 starts again, transporting the packaging bag 5 containing the speaker product 7 to the next sealing process. Thus, the complete automatic bagging cycle is completed.

[0023] Working principle: When connecting, the quick-connect mechanism 9 inserts the connector 908 directly into the tubular end of the connecting tube 901. The beveled end of the connector 908 pushes the retaining ball 905 radially outward. After full insertion, the rotating shell 902, in the locked position, is pressed back by the pressing surface of its inner wall under the force of the spring 907. This causes the retaining ball 905 to simultaneously engage in the locking groove of the connector 908 and the through hole of the connecting tube 901, achieving self-locking. When disconnection is required, the operator needs to manually rotate the rotating shell 902. This rotation compresses the spring 907 and causes the rotating shell 902 to undergo slight axial and circumferential displacement until the unlocking groove 903 on the inner wall of the rotating shell 902 rotates to a position directly opposite the retaining ball 905. At this time, the unlocking groove 903 provides radial retraction space for the retaining ball 905. The force of pulling out the connector 908 forces the retaining ball 905 to retract into the unlocking groove 903, thereby releasing the lock and achieving quick separation. When adjusting the spacing between the support rods 303, the operator uses a tool to rotate the rotating head 304. The rotating head 304 drives the threaded rod 306 to rotate. Since the threaded rod 306 is axially limited by the fixing plate 308, the rotational movement of the threaded rod 306 drives two threaded blocks 305 to move towards or away from each other along the axis of the threaded rod 306 through two threads with opposite directions. Because the support rods 303 are fixed on the threaded blocks 305, the distance between the two support rods 303 is adjusted synchronously and symmetrically.
