Description

Technical Field

[0001] The invention belongs to the technical field of packaging, and provides a device that can not only perform fixed punching and tape application on foam boxes, but also perform flipping and transportation after punching and double-sided tape application, and particularly relates to an automatic packaging device for foam boxes. Background Art

[0002] When storing items that require air circulation, such as fresh fruits and vegetables, punching holes can allow air to circulate better in the foam box, preventing items from deteriorating or rotting due to lack of oxygen or accumulation of carbon dioxide, thus extending the shelf life. For items that need to release moisture or odor during transportation or storage, such as seafood and flowers, punching holes can also help release moisture and odor, keeping the environment inside the box dry and fresh. When foam boxes are used to pack items that may produce moisture, such as frozen food that will produce blood during thawing, and some plants that may leak moisture during transportation, the punching holes can be used as drainage holes to drain the moisture in the box in time to prevent moisture from accumulating in the box and causing damage to items or breeding bacteria. Gluing can firmly stick the lid and body of the foam box together to prevent the lid from opening accidentally during handling and transportation, ensuring the safety of the items in the box. For some items that need to be separated or fixed in the foam box, such as fragile glass products, ceramic products, etc., gluing can be used to stick the partition or cushioning material to the inner wall of the foam box to keep the items in a stable position in the box, reduce shaking and collision, and avoid damage.

[0020] Specifically, the transparent tape 422 is put on the adhesive roller 403, passes through the first roller 406, the second roller 408, the third roller 410, the lever 412, and the first pressure wheel 414. When the foam box is fixed, the first pressure wheel 414 presses the transparent tape 422 over the foam box. After completely rolling over the foam box, the cutter 416 immediately cuts off the transparent tape 422 due to the elastic potential energy of the coil spring, and the slider 401 moves on the slide frame track 402, so that the transparent tape 422 can be affixed along all four sides of the foam box.

[0021] In this embodiment, the slider 401 can slide along the slide frame track 402 to drive the entire glue sticking mechanism to move along the track. The slide frame track 402 is fixed to the bottom of the cover plate 2 to provide a sliding path for the slider 401 to ensure that the slider 401 moves smoothly.

[0023] Example 3 like Figure 1 , 6As shown, based on the same concept as the above-mentioned embodiments 1 and 2, this embodiment further proposes an automatic punching mechanism 6 including a telescopic hydraulic cylinder 601, a spring 602, a curved plate 603, a transverse groove 604, an arc block 605, a punch 606, a slide rod 607 and a counterweight block 608; The telescopic hydraulic cylinder 601 is installed at the middle position of the bottom of the cover plate 2, the spring 602 is sleeved on the output shaft of the telescopic hydraulic cylinder 601, the curved plate 603 is fixed on the output shaft of the telescopic hydraulic cylinder 601, the transverse groove 604 is opened on the curved plate 603, the slide bar 607 is slidably installed in the transverse groove 604, one end of the arc block 605 is sleeved on the slide bar 607, the counterweight block 608 is fixed to the bottom end of the slide bar 607, and the punch 606 is inserted into the other end of the arc block 605; The spring 602 is used for buffering and returning to the original position after punching, and the punch 606 is a combination of terminals of various sizes.

[0024] Specifically, when punching is required, the user starts the telescopic hydraulic cylinder 601, the telescopic hydraulic cylinder 601 drives the curved plate 603, the curved plate 603 drives the arc block 605, and the arc block 605 drives the punch 606. Since the punch 606 is a combination of multiple sizes, the punch 606 can punch out positioning holes of various sizes and adjust them according to user needs. The position of the punching can also be adjusted by rotating the arc block 605 or toggling the slide bar 607 to drive the arc block 605 to move along the horizontal groove 604. The punching position can be adjusted 360 degrees in all directions.

[0025] In this embodiment, the telescopic hydraulic cylinder 601 serves as a power source, and provides the force required for punching through telescopic action. It is installed in the middle position of the bottom of the cover plate 2 and is the power source of the entire punching mechanism. The spring 602 is sleeved on the output shaft of the telescopic hydraulic cylinder 601, and is used for buffering and returning to the original position after punching, ensuring that the punch 606 can quickly return to its original position after punching, reducing the damage to the machine caused by the impact. The curved plate 603 is fixed on the output shaft of the telescopic hydraulic cylinder 601, and converts the linear motion of the telescopic hydraulic cylinder 601 into the rotational motion of the curved plate 603, thereby driving the arc block 605 and the punch 606. The transverse groove 604 is opened on the curved plate 603, providing a sliding path for the slide bar 607, allowing the arc block 605 to move along the transverse groove 604 to adjust the punching position. One end of the arc block 605 is sleeved on the slide bar 607, and the other end Insert the punch 606, and the arc block 605 rotates with the rotation of the curved plate 603, driving the punch 606 to perform the punching operation. The punch 606 is inserted at the other end of the arc block 605, and is the component that directly contacts the material for punching. Since the punch 606 is a combination of terminals of various sizes, it can punch out positioning holes of various sizes. The slide bar 607 is slidably installed in the transverse groove 604. The movement of the slide bar 607 drives the arc block 605 to move along the transverse groove 604 to adjust the punching position. The counterweight block 608 is fixed to the bottom end of the slide bar 607 to increase the stability of the slide bar 607 and prevent the slide bar 607 from unnecessary vibration or displacement during the punching process. The combination of terminals of various sizes means that the punch 606 can replace terminals of different sizes according to different needs to adapt to the needs of different apertures.

[0026] Through the coordinated work of these components, the automatic punching mechanism 6 can realize the automation of the punching operation. At the same time, by adjusting the arc block 605 or toggling the slide bar 607, the punching position can be adjusted 360 degrees in all directions, thereby improving the flexibility and accuracy of the punching. This design enables the punching mechanism to adapt to different punching requirements, thereby improving production efficiency and product adaptability.

[0027] Workflow: S1. First, place the un-taped foam boxes correctly on the conveyor line, and supply the foam boxes smoothly and continuously through rollers, guide devices and tension control systems; S2. After the loading is completed, it is then fixed on the automatic turning mechanism 3 through the clamping device 309. The user starts the telescopic hydraulic cylinder 601, and the telescopic hydraulic cylinder 601 drives the curved plate 603, the curved plate 603 drives the arc block 605, and the arc block 605 drives the punch 606. Since the punch 606 is a combination of various sizes, the punch 606 can punch out positioning holes of various sizes, which can be adjusted according to user needs. The arc block 605 can also be rotated or the slide bar 607 can be driven to move along the horizontal groove 604 to adjust the punching position. The punching position can be adjusted 360 degrees in all directions. The automatic punching mechanism 6 is used to punch out holes for drainage and ventilation on the foam box to ensure that the hole position is accurate, in preparation for subsequent assembly and fixation; S3, then use the automatic punching mechanism 6 to punch holes on the transparent tape 422 corresponding to the foam box, and the punched waste transparent tape and waste foam will fall into the waste box 5 for centralized collection; S4, then put the transparent tape 422 with holes punched in advance on the adhesive roller 403, and pass one end of the tape through the first roller 406, the second roller 408, the third roller 410, the lever 412, and the first pressing wheel 414. When the foam box is fixed, the first pressing wheel 414 presses the transparent tape 422 over the foam box. After completely rolling over the foam box, the cutter 416 immediately cuts the transparent tape 422 due to the elastic potential energy of the coil spring, and the slider 401 runs on the slide frame track 402, so that the transparent tape 422 can be attached to all sides of the foam box; S5. After the two upper foam box boards are glued, the clamping device 309 releases the foam box, the telescopic cylinder 311 shortens the output shaft, the foam box is placed on the belt 306, and then the second motor 313 is started. The output shaft of the second motor 313 first rotates forward to drive the driven shaft 308 to rotate, and the driven shaft 308 drives the roller group 307 to rotate, and the roller group 307 drives the belt 306 to move forward until half of the foam box moves out of the clamping device 309, and then the telescopic cylinder 311 is extended to push the foam box to stand sideways, shorten the telescopic cylinder 311, and then the second motor 313 is reversed, the belt 306 moves backward with the foam box, and the telescopic cylinder 311 is extended again to push the foam box standing sideways to tilt forward, and the flipping is completed; S6, immediately after turning over, glue the reverse side, and glue the reverse side in the same way. After the post-glue gluing is completed, the clamping device 309 releases the foam box, the telescopic cylinder 311 shortens the output shaft, and the foam box is placed on the belt 306, and then the second motor 313 is started, the output shaft of the second motor 313 drives the driven shaft 308 to rotate, the driven shaft 308 drives the roller group 307 to rotate, the roller group 307 drives the belt 306 to move forward, and the belt 306 drives the processed foam box to enter the next process; S7, finally collect the processed foam boxes and unused scotch tape 422, and centrally process the waste foam and waste scotch tape collected in the waste box 5.
