Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, specifically to an automatic heat-sealing and slitting device for multi-unit aluminum foil packaging. Background Technology

[0002] In industries such as medical devices and food, products are often packaged using aluminum foil blister packs. To facilitate production and transportation, multiple independent blister units are usually pre-assembled into multi-unit packages, such as two- or four-unit packages. Before final packaging, these multi-unit packages need to be cut into individual units, and their edges are heat-sealed to ensure airtightness.

[0003] Currently, this process is mostly completed by semi-automatic equipment or manual labor, which has the following significant drawbacks: manual feeding and receiving are labor-intensive; manual placement is prone to positioning deviations, resulting in poor heat sealing, rough cutting, curling edges or incomplete sealing, causing product leakage and scrap; the collection of finished products after cutting and the disposal of edge waste usually require additional manual operation. The process is discrete, making it impossible to achieve full automation, resulting in low efficiency and poor quality consistency.

[0004] Therefore, there is an urgent need for a specialized device that can achieve full automation, high precision, high efficiency, and ensure the quality of cutting and sealing. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic heat-sealing and slitting device for multi-unit aluminum foil packaging. This device can realize full automation from feeding, positioning, heat sealing, slitting, finished product collection and waste disposal, effectively improving production efficiency, processing accuracy and product quality consistency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] The positioning mechanism is located at the feed end of the frame and is used to position and guide the multi-unit aluminum foil packaging placed on the conveying device in the width direction.

[0009] The heat sealing mechanism and the cutting mechanism are arranged sequentially along the conveying direction of the conveying device, and are respectively used to heat seal the outer perimeter of the predetermined cutting line of the aluminum foil packaging and to cut along the inner side of the heat sealing line;

[0010] The cleaning mechanism is located at the discharge end of the frame and is used to remove residual edge waste after slitting.

[0016] Furthermore, the cleaning mechanism includes an air duct fixed to the frame, several branch pipes connected to the air duct, and an air blowing nozzle located at the bottom of the branch pipe; a collection box is provided at the bottom of the frame corresponding to the position of the air blowing nozzle.

[0017] Furthermore, it also includes an automatic material handling device, which includes a linear guide rail mounted on the rear side of the cutting mechanism, a slider driven by a second drive device to slide along the linear guide rail, and a suction cup mounted on the bottom of the slider and driven by a third drive device.

[0018] Furthermore, the frame is also equipped with photoelectric sensors to detect the material feeding status and processing station status, and to feed the signals back to the control system.

[0030] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0031] like Figures 1 to 5As shown, the present invention provides an automatic heat-sealing and slitting device for multi-unit aluminum foil packaging, including a frame 1, a conveying device, a positioning mechanism 8, a heat-sealing mechanism, a cutting mechanism, a cleaning mechanism 10, an automatic material handling device, and a control system.

[0032] The conveying device includes two sets of motor-driven transmission chains 2, with several equidistant positioning shafts 3 fixed between the transmission chains 2 for supporting the blister pack portion of the aluminum foil packaging.

[0033] The positioning mechanism 8 is installed at the front end of the frame 1. Its adjusting rod 13 drives two shaft blocks 14 with positioning plates 15 to move synchronously in opposite directions through positive and negative threads, thereby precisely limiting the placement width of the aluminum foil packaging.

[0034] The heat-sealing mechanism consists of an upper heat-sealing mold 4 and a lower heat-sealing mold 17, while the cutting mechanism consists of an upper cutting mold 5 and a lower cutting mold 18. The upper heat-sealing mold 4 and the upper cutting mold 5 are mounted on the top of the frame via a first drive device. The lower heat-sealing mold 17 and the lower cutting mold 18 are mounted inside the frame via a guide frame 19 and a lifting cylinder 20 (forming a lifting mechanism 9), enabling them to rise and close with the upper mold.

[0035] The suction cup 7 of the automatic material handling device is mounted on the slider of the linear guide rail 6 via a third drive device, and the slider is driven to move laterally by a second drive device.

[0036] The air duct 21 of the cleaning mechanism 10 is fixed to the rear end of the frame, and it is connected to multiple downward blowing nozzles 23 through a diversion pipe 22. A collection box 24 is provided at the bottom of the frame 1.

[0037] Two sets of through-beam photoelectric sensors 11 are installed on the frame 1, located behind the positioning mechanism 8 and the heat-sealing upper mold 4 respectively, for detecting the material being released into place and conveyed to the processing station.

[0038] The control system (not shown in the figure, but may be a PLC) is electrically connected to the motor, various drive devices, lifting cylinder 20, photoelectric sensor 11, etc.

[0039] The workflow is as follows:

[0040] 1. Loading and Positioning: Adjust the distance between the two positioning plates 15 by rotating the rocker arm 16 according to the width of the aluminum foil package. The operator places the multi-unit aluminum foil package on the positioning shaft 3, positioning it between the two positioning plates 15. The front-end photoelectric sensor 11 detects the material.

[0041] 2. Conveying and Heat Sealing: The control system starts the motor, driving the transmission chain 2 to deliver the package to the heat sealing station. After the rear photoelectric sensor 11 detects the positioning, the motor stops. The upper heat sealing mold 4 presses down, while the corresponding lifting cylinder 20 pushes the lower heat sealing mold 17 up, heating and pressurizing the edges of the package to complete the sealing.

[0042] 3. Conveying and Slitting: The drive chain 2 delivers the heat-sealed packaging to the cutting station. The upper cutting die 5 is pressed down, and the corresponding lifting cylinder 20 pushes the lower cutting die 18 up to complete the slitting and obtain an independent sealing unit.

[0043] 4. Automatic material handling: The transmission chain 2 delivers the finished product to the material handling station. The suction cup 7 descends to pick up the finished product, then rises and moves laterally along the linear guide rail 6 to the top of the storage basket next to the frame for release.

[0044] 5. Waste removal: The cut frame waste is conveyed to the end of the frame by the transmission chain 2 and falls off after being flipped by the sprocket. At the same time, the external blower sends air to the air duct 21 and blows it out through the air nozzle 23 to blow off the waste that may be stuck on the positioning shaft 3. All the waste finally falls into the collection box 24.

[0045] 6. Cyclic Process: While steps 2-5 are being performed, the next package to be processed can be placed at the front end to achieve continuous automated production.

[0046] The control logic of this utility model is conventional technology in the field, and its circuit connection and program compilation can be realized by existing technology. The core of this utility model lies in the innovative integration and layout of the above-mentioned mechanical structure.

[0047] The above description is merely a preferred embodiment of this utility model and does not limit its patent scope. Any equivalent structural modifications made based on the description and drawings of this utility model, or direct / indirect applications to other related technical fields, should be included within the protection scope of this utility model.
