Description

Technical Field

[0001] This application relates to the technical field of packaging machine installation, and more specifically, to a drawer-type blanking device for a packaging machine. Background Art

[0002] A packaging machine is a machine that packages products in a plastic-sealed structure. The plastic-sealed structure is used to protect the products and make them look nice. The packaging machine uses a drawer-type blanking device to improve the feeding and discharging efficiency. It usually consists of one or more drawers that can move horizontally. The design of the drawers makes the installation and disassembly of product materials and plastic-sealing materials more convenient and fast, thus improving the blanking efficiency. The traditional blanking device of a packaging machine requires a separate horizontal driving device to make the drawer slide out horizontally and cannot move synchronously and coordinately with the heat-sealing plate. Generally, a vertical driving mechanism needs to be set up separately for the heat-sealing plate, resulting in the inability to achieve synchronous movement between the heat-sealing plate and the drawer. This not only reduces the feeding and discharging efficiency but also increases the equipment investment and energy consumption due to the installation of more driving mechanisms. In view of this, we propose a drawer-type blanking device for a packaging machine. Summary of the Utility Model

[0021] By adopting the above technical solution, the packaging structure of the heat-sealing packaging machine 1 is composed of a drawer die base 3 and a heat-sealing plate 7. The built-in heating device of the heat-sealing packaging machine 1 can heat-treat the heat-sealing plate 7. By placing hard plastic boxes and sealing paper bags in two rows of multiple die slots 31 provided on the drawer die base 3, and by moving the heat-sealing plate 7 downward and cooperating with the drawer die base 3, the encapsulation packaging treatment of the hard plastic boxes and the sealing paper bags can be realized. In order to facilitate the quick blanking treatment of the drawer die base 3 after the encapsulation packaging, the drawer die base 3 is threadedly installed on the sliding drawer 2. By using the switch device 5, the electric cylinder 41 can be electrically started, so that the concave slide 42 drives the heat-sealing plate 7 and the rack 43 to move up and down. The rack 43 drives the gear 44 and the lead screw 45 to rotate, and the purpose of the sliding drawer 2 sliding horizontally along the guide rail 6 can be achieved. Thus, when the sliding drawer 2 slides into the interior of the heat-sealing packaging machine 1, the heat-sealing plate 7 can press the drawer die base 3 to achieve the purpose of encapsulation packaging. When the heat-sealing plate 7 moves upward, the drawer die base 3 will slide out along the guide rail 6 to the extension plate 13 with the sliding drawer 2, thereby facilitating the blanking treatment of the encapsulated and packaged hard plastic boxes.

[0022] Refer to Figure 2 and Figure 3 , a rectangular guide cavity 11 is provided on the back of the heat-sealing packaging machine 1, and guide grooves 12 are provided on both sides of the heat-sealing packaging machine 1 where the rectangular guide cavity 11 is located.

Thus, the heat-sealing plate 7 can achieve the purpose of stable displacement up and down.

[0024] Refer to Figure 3 andFigure 4 On the upper surface of the sliding drawer 2, an embedding groove 21 is provided. The drawer mold base 3 is embedded and installed in the embedding groove 21. On both side surfaces of the drawer mold base 3, connecting blocks 32 are fixedly provided, and a screw rod 33 is threadedly installed between the connecting block 32 and the sliding drawer 2.

[0025] By adopting the above technical solution, the drawer mold base 3 is embedded and installed in the embedding groove 21 of the sliding drawer 2, and is fixedly installed by using the screw rod 33 through threading.

[0026] Refer to Figure 3 and Figure 4 On the upper end of each mold cavity 31 of the drawer mold base 3, a paper sealing groove 311 and a C-shaped blanking groove 312 are provided. The cross-section of the mold cavity 31 and the paper sealing groove 311 is of a convex structure.

[0027] By adopting the above technical solution, the hard plastic box to be packaged is pre-placed in the mold cavity 31, and the upper edge of the hard plastic box is limited at the paper sealing groove 311. Then, the packaging bag for encapsulation is placed on the upper part of the hard plastic box. When the drawer mold base 3 slides along the two guide rails 6 with the sliding drawer 2 into the internal part of the heat-sealing packaging machine 1, the maximum stroke of the piston rod of the electric cylinder 41 just enables the heat-sealing plate 7 to press the paper sealing bag, so as to achieve the purpose of heat-sealing packaging.

[0028] Refer to Figure 2 and Figure 3 At the four corners of the bottom surface of the sliding drawer 2, a slider 22 is fixedly provided at each corner. The slider 22 is slidably connected to the corresponding guide rail 6. A screw block 23 is fixedly provided on the bottom surface of the sliding drawer 2, and the screw block 23 is threadedly connected to the lead screw 45.

[0029] By adopting the above technical solution, the sliding drawer 2 horizontally slides along the two parallel guide rails 6 through the four sliders 22. Thus, when the lead screw 45 rotates, the sliding drawer 2 is driven to horizontally displace through the screw block 23.

[0030] Refer to Figure 2 and Figure 3 Inside the heat-sealing packaging machine 1, a power supply device and a power supply circuit are provided for electrically connecting the electric cylinder 41, and a power cord 51 is electrically connected between the switch device 5 and the electric cylinder 41.

[0031] By adopting the above technical solution, by manually controlling the switch device 5, the piston rod of the electric cylinder 41 can be controlled to stretch and retract, so as to achieve the purpose of moving the heat-sealing plate 7 up and down.

[0032] Working principle: The packaging structure of the heat-sealing packaging machine 1 consists of a drawer die base 3 and a heat-sealing plate 7. The heat-sealing packaging machine 1 is internally provided with a heating device to heat-treat the heat-sealing plate 7. By placing hard plastic boxes and sealing paper bags in multiple die slots 31 arranged in two rows opened in the drawer die base 3, and by moving the heat-sealing plate 7 downward and cooperating with the drawer die base 3, the packaging process of the hard plastic boxes and the sealing paper bags can be realized. In order to facilitate the quick blanking of the drawer die base 3 after packaging, the drawer die base 3 is threadedly installed on the sliding drawer 2. Using the switch device 5, the electric cylinder 41 can be electrically started, so that the concave sliding frame 42 drives the heat-sealing plate 7 and the rack 43 to move up and down. The rack 43 drives the gear 44 and the lead screw 45 to rotate, and the purpose of the horizontal sliding of the sliding drawer 2 along the guide rail 6 can be achieved. Thus, when the sliding drawer 2 slides into the heat-sealing packaging machine 1, the heat-sealing plate 7 can press the drawer die base 3 to achieve the packaging purpose. When the heat-sealing plate 7 moves upward, the drawer die base 3 will slide out along the guide rail 6 to the extension plate 13 with the sliding drawer 2, thus facilitating the blanking of the packaged hard plastic boxes.
