Description

Technical Field

[0001] This utility model relates to the field of paper and plastic product processing technology, specifically a paper and plastic product feeding and trimming mechanism. Background Technology

[0002] Paper-plastic products, such as disposable lunch boxes, require edge trimming after molding to remove excess material from the product edges. Existing edge trimming machines require operators to manually place the paper-plastic product onto the machine and manually remove it after trimming. Because lunch boxes are thin, lightweight, and easily deformed, they are difficult to handle, especially once placed on the trimming mold. Furthermore, the lunch boxes are easily deformed during handling. If multiple lunch boxes need to be cut at once, the efficiency of handling is also low.

[0003] Therefore, we designed this feeding and trimming mechanism, which can realize automatic feeding and discharging of paper and plastic products without the need to pick up and put down materials, and can greatly improve trimming efficiency. Utility Model Content

[0013] 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. Example 1

[0014] Please see Figure 1-4 This embodiment provides a paper-plastic product feeding and trimming mechanism, including a frame 1, and further including... The edge-trimming assembly is used to perform edge-trimming operations on paper-plastic products. Specifically, the edge-trimming assembly is an edge-trimming machine, a conventional paper-plastic product edge-trimming machine. It includes a hydraulic cylinder 6 fixedly mounted on a frame 1, with a lower edge-trimming mold 7 fixedly connected to the output end of the hydraulic cylinder 6. Guide brackets 8 are fixedly mounted on the frame 1, passing through the four corners of the lower edge-trimming mold 7 and slidably connected to it. An upper edge-trimming mold 9, corresponding to the lower edge-trimming mold 7, is fixedly mounted on the upper end of the guide brackets 8. The upper edge-trimming mold 9 is equipped with corresponding blades. By placing the paper-plastic product onto the lower edge-trimming mold 7 and lifting it with the hydraulic cylinder 6, the lower edge-trimming mold 7 and the upper edge-trimming mold 9 are aligned, thus achieving edge trimming. This is a conventional and universally used piece of equipment, and will not be further described in detail.

[0015] It also includes a processing storage platform 3 for placing paper-plastic products to be trimmed; and a finished product storage platform 2 for placing paper-plastic products after trimming; such as Figure 1 As shown, the processing storage platform 3 and the finished product storage platform 2 are located on both sides of the trimming assembly. Taking a lunch box as an example, the lunch boxes to be processed are stacked on the processing storage platform 3, and the lunch boxes after trimming are stacked on the finished product storage platform 2.

[0016] It also includes a feeding component and a picking component. The feeding component is located above the processing storage platform 3 and is used to transport the paper and plastic products on the processing storage platform 3 to the edge cutting component. The picking component is located above the finished product storage platform 2 and is used to transport the paper and plastic products that have been edge-cut on the edge cutting component to the finished product storage platform 2.

[0017] Specifically, such as Figure 1-3 As shown, the feeding assembly and the picking assembly have the same structure. The feeding assembly and the picking assembly each include a lifting and horizontally movable feeding suction cup frame 5 and a picking suction cup frame 4, respectively. The feeding suction cup frame 5 and the picking suction cup frame 4 are located above the material storage platform 3 and the finished product storage platform 2, respectively. Both the feeding suction cup frame 5 and the picking suction cup frame 4 are equipped with multiple negative pressure suction cups 22 for picking up materials. Figure 2-3As shown, to achieve the movement of the suction cup frame, upper support plates 10 are fixedly installed on both sides of the top of the frame 1, located above the feeding suction cup frame 5 and the picking suction cup frame 4, respectively. A horizontally movable sliding plate 12 is installed on the upper support plate 10, and a first motor 15 is fixedly installed on the sliding plate 12 to drive its movement on the upper support plate 10. Specifically, a guide rail 11 is fixedly installed on the upper support plate 10, and the sliding plate 12 is slidably mounted on the guide rail 11. A horizontally fixed rack 13 is also fixedly installed at the upper end of the upper support plate 10, located below the sliding plate 12. A first gear 14 is rotatably mounted at the bottom of the sliding plate 12, meshing with the horizontally fixed rack 13. The first motor 15 drives the first gear 14 to rotate, and when the first gear 14 rotates, it... The sliding plate 12 moves along the horizontal fixed rack 13 and the guide rail 11. A vertically lifting rack 18 that can be raised and lowered is provided on the sliding plate 12, and a second motor 19 is used to drive the vertically lifting rack 18. The vertically lifting racks 18 on both sides pass through the sliding plate 12 and are fixedly connected to the feeding suction cup frame 5 and the picking suction cup frame 4 respectively. Specifically, a mounting plate 16 is fixedly provided on the sliding plate 12, and a guide slider 17 is fixedly provided on the mounting plate 16. The vertically lifting rack 18 is slidably connected to the guide slider 17. A second gear 20 that meshes with the vertically lifting rack 18 is rotatably provided on the mounting plate 16. The second motor 19 is used to drive the second gear 20 to rotate. When the second gear 20 rotates, it drives the vertically lifting rack 18 to move up and down. Meanwhile, the lower ends of the two vertical lifting racks 18 are each fixedly connected to a connecting rod 21, which is used to connect to the material picking suction cup frame 4 and the material discharging suction cup frame 5 respectively, so that the material picking suction cup frame 4 and the material discharging suction cup frame 5 can smoothly reach the top of the cutting edge lower die 7.

[0018] It should be noted that after the paper-plastic product is trimmed, some trimmed material will remain on the mold. According to the technical solution in this application, after the material suction cup 4 removes the trimmed paper-plastic product, the trimmed material can be quickly removed manually without affecting the paper-plastic product; in addition, referring to Figure 4 As shown, a material receiving plate 23 can also be fixedly installed on the upper end of the material suction cup frame 4. By evenly distributing multiple negative pressure suction heads corresponding to the edge material on the upper cutting mold 9, after the cutting is completed and the upper and lower molds are separated, the edge material is adsorbed onto the upper cutting mold 9 by the negative pressure suction heads. When the material suction cup frame 4 adsorbs the paper-plastic product on the lower cutting mold 7, the negative pressure suction heads on the upper cutting mold 9 stop adsorbing the edge material, and the edge material falls onto the material receiving plate 23 at the same time. It then moves with the material suction cup frame 4 to the top of the finished product storage platform 2, where it can be quickly removed manually. The design of setting negative pressure suction heads or opening negative pressure suction holes on the upper cutting mold 9 is a conventional mold design familiar to those skilled in the art, and this application will not elaborate further.

[0019] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and features of this application. Solutions or features that are prior art or common knowledge to those skilled in the art will not be described in detail in the above embodiments.

[0020] Furthermore, the technical solutions of this application are not limited to the above embodiments. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
