Description

A material handling device for a high-speed heat shrink packaging machine Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically to a material handling device for a high-speed heat shrink packaging machine. Background Technology

[0002] High-speed heat shrink packaging machines are mainly used for the automated lamination and sealing of packaging boxes. The equipment automatically feeds the material via a conveyor belt, precisely wrapping the heat shrink film around the surface of the packaging box. After being heated and shrunk, the film adheres tightly to the box, forming a transparent protective layer that is both moisture-proof and dust-proof, while also enhancing the display and sales effect. Finally, the finished product is automatically unloaded via a conveyor belt.

[0003] During the unloading process, a collection box is usually placed at the exit end of the conveyor belt (as shown in Figure 7). One or two workers pick up the unloaded packaging boxes and stack them. However, the packaging boxes are continuously falling from the conveyor belt. Before the previous packaging box can be successfully stacked, the next packaging box is unloaded. During long working hours, the workers often do not have time to stack them, resulting in a messy unloading site and frequent occurrences of uneven stacking. Summary of the Invention

[0004] The purpose of this invention is to provide a material handling device for a high-speed heat shrink packaging machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a material handling device for a high-speed heat shrink packaging machine, comprising a packaging machine body and a support frame, and further comprising:

[0006] Vertical plates are bolted to both sides of the top of the bracket. Several rotating rollers are rotatably connected to the opposite side of the vertical plates. A diversion channel is welded to one side of the vertical plate. A connecting plate is also welded to the side of the diversion channel near the vertical plate. Fixing blocks are bolted to the upper and lower parts of one side of the connecting plate. A rotating column is provided through the surface of the fixing block, and the rotating column and the fixing block are fixed to each other by bearings. A transmission gear is bolted to the upper surface of the rotating column.

[0007] A support plate is bolted to the top of the vertical plate, and an electric cylinder is bolted to the top of the support plate. A connecting rod is bolted to the output shaft of the electric cylinder. A rack is meshed with one side of the transmission gear, and the rack is bolted to the connecting rod. A frame is welded to one side of the rotating column, and auxiliary rollers are rotatably connected to both sides inside the frame.

[0008] Preferably, a sliding rod is also bolted to the top of the vertical plate, and a sliding sleeve is also bolted to one side of the rack, with the sliding sleeve and the surface of the sliding rod being slidably connected.

[0009] Preferably, limiting plates are also bolted to both sides of the slide bar surface, and the limiting plates are circular in design.

[0010] Preferably, an infrared sensor is also fixed to the surface of the vertical plate.

[0011] Preferably, the auxiliary rollers are located on the inner side of the frame in an alternating design.

[0012] Preferably, the diversion channel is arc-shaped, and there are two sets of diversion channels.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention uses the guiding action of the frame and auxiliary rollers to guide the packaging boxes into the diversion channel on one side after they are unloaded. By activating the electric cylinder to extend or shorten its output shaft, the rack moves, which in turn drives the transmission gear and rotating column to rotate, changing the position of the frame and auxiliary rollers. This allows the packaging boxes to enter the diversion channels on both sides in batches, preventing the unloaded boxes from concentrating and facilitating the sorting and stacking work for the staff on both sides.

Detailed Implementation

[0023] 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.

[0024] Please refer to Figures 1-7. A material handling device for a high-speed heat shrink packaging machine includes a packaging machine body 1 and a support 2. Vertical plates 3 are bolted to both sides of the top of the support 2. Several rotating rollers 4 are rotatably connected to the opposite side of the vertical plates 3. A diversion channel 5 is welded to one side of the vertical plates 3. The diversion channel 5 is arc-shaped and there are two sets of diversion channels 5. A connecting plate 6 is also welded to the side of the diversion channel 5 near the vertical plate 3. Fixing blocks 7 are bolted to the upper and lower parts of one side of the connecting plate 6. A rotating column 8 is provided through the surface of the fixing block 7, and the connection between the rotating column 8 and the fixing block 7 is fixed by bearings. The rotating column 8 is fixed so that it can rotate. A transmission gear 9 is bolted to the top of the rotating column 8. A support plate 10 is bolted to the top of the vertical plate 3. An electric cylinder 11 is bolted to the top of the support plate 10. A connecting rod 12 is bolted to the output shaft of the electric cylinder 11. A rack 13 is meshed with one side of the transmission gear 9 and is bolted to the connecting rod 12. Under the action of the connecting rod 12, the rack 13 and the output shaft of the electric cylinder 11 are fixed to each other. A frame 14 is welded to one side of the rotating column 8. Auxiliary rollers 15 are rotatably connected to both sides inside the frame 14. The auxiliary rollers 15 are located inside the frame 14 in an alternating design.

[0025] A sliding rod 16 is also attached to the top of the vertical plate 3, and a sliding sleeve 18 is attached to one side of the rack 13. The sliding sleeve 18 is slidably connected to the surface of the sliding rod 16. During the movement of the rack 13, the sliding sleeve 18 can be driven to slide along the surface of the sliding rod 16, increasing the stability of the movement of the rack 13. Limiting plates 17 are also attached to both sides of the surface of the sliding rod 16. The limiting plates 17 are circular in design and are used to limit the range of movement of the sliding sleeve 18 on the surface of the sliding rod 16 and to limit the range of movement of the rack 13.

[0026] An infrared sensor 19 is also fixed on the surface of the vertical plate 3. During operation, the infrared sensor 19 and the electric cylinder 11 are connected to the PLC controller in the packaging machine body 1 (not shown in the figure, the PLC controller is existing technology).

[0027] During operation, the electric cylinder 11 is activated, extending its output shaft. This extends the connecting rod 12 and rack 13, causing the transmission gear 9 and rotating column 8 to rotate counterclockwise (from the perspective of Figure 1 or Figure 2). This causes the frame 14 to align to one side and fit against the vertical plate 3. Boxes for collecting finished packaging boxes are placed below the diversion channels 5 on both sides. Packaging boxes discharged from the outlet of the packaging machine body 1 fall onto the surface of the rotating roller 4 and slide down its surface. Simultaneously, the infrared sensor 19 detects the passing of a packaging box. The packaging box then contacts the auxiliary roller 15 and, guided by the auxiliary roller 15, enters one side of the connecting plate 6, then one of the diversion channels 5. The next packaging box then enters the same diversion channel 5 on the same side. After two packaging boxes are discharged (the PLC control can be adjusted), the process continues. The program (e.g., changing the position of frame 14 for three or four packages) allows workers on that side of the diversion channel 5 to pick up and stack the packages in the collection box placed below the diversion channel 5. When the infrared sensor 19 detects the passing of the third package, the output shaft of the electric cylinder 11 quickly retracts, driving the rack 13 to approach the electric cylinder 11 and causing the frame 14 to move to the other side, thus contacting another set of vertical plates 3. At this time, after the package comes into contact with the auxiliary roller 15, it enters the interior of another set of diversion channels 5. This achieves the sorting of the unloading, allowing the package to enter the diversion channels 5 on both sides in batches. While a package is entering one of the diversion channels 5, the workers on the other side can use the interval time to stack the packages, so that the workers can pick up and stack them without being overwhelmed. This allows the workers to collect and stack the packages.
