Description

Technical Field

[0001] The invention relates to the technical field of card bag production equipment, in particular to a card bag making machine. Background Art

[0002] Card bags are generally used to store cards such as IC cards and commemorative cards for protection from scratches. Generally, card bags are made of PE film through folding, sealing, cutting and other processes. However, the card bags made by this single-material bag-making process have relatively single uses. For example, it is difficult to achieve the effect of one side being transparent and the other side being matte. Therefore, composite film bag-making machines suitable for different materials have appeared on the market. The upper and lower stacked structures are used to combine two films by gluing, hot melting and other methods to form a bag body. For example, the Chinese invention patent "A composite packaging bag production method" (Announcement No. CN101670685B, announcement date 2011.07.20) provides a composite packaging bag production method, which is to dry-combine non-woven fabrics and PE films to obtain composite films and then pass through a bag-making machine to form composite packaging bags. However, the above bag-making method still requires folding the film in half to form a tube material and then heat-sealing and cutting the film to make the bag, and still cannot achieve the effect of different functions on both sides of the bag body. Summary of the invention

[0003] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.

[0004] A card bag making machine comprises a frame, a first feeding mechanism installed at one end of the frame, a second feeding mechanism and a receiving mechanism installed at the other end of the frame, the first feeding mechanism is loaded with a rolled film material strip, the second feeding mechanism is loaded with a rolled base material strip, the base material strip is provided with a U-shaped hot melt adhesive strip, a heating workbench is installed on the frame, a hot pressing plate is arranged above the heating workbench, a pressing strip aligned with the hot melt adhesive strip is arranged at the bottom of the hot pressing plate, and lifting cylinders for driving the hot pressing plate to rise and fall are also installed on both sides of the heating workbench, the film material strip is covered on the base material strip and fed into the heating workbench so that the two are adhered together by the hot melt adhesive strip to form a bag body material strip, which is then rolled up by the receiving mechanism.

[0005] Furthermore, two rows of hot-melt adhesive strips are provided on the base material strip, and a cutting line is provided between the two rows of hot-melt adhesive strips. A slitting mechanism is also installed on the frame on the outlet side of the heating workbench. The slitting mechanism includes a slitting bracket fixedly installed on the frame, and a cutting shaft is installed on the slitting bracket to rotate with the slitting bracket. The cutting shaft is provided with a cutting wheel for cutting the bag material strip along the slitting line.

[0006] Furthermore, the material receiving mechanism includes a material receiving bracket fixedly installed at the rear end of the frame and a first material receiving roller and a second material receiving roller rotatably installed on the material receiving bracket. The material receiving bracket is also equipped with a slitting roller group that tears the bag material strip along the slitting line and guides it into the first material receiving roller and the second material receiving roller respectively.

[0007] Furthermore, the cutting blade shaft is provided with cutting blade wheels on both sides of the bag material strip.

[0008] Furthermore, a heat dissipation fan is fixedly installed on the slitting bracket.

[0009] Furthermore, a pressing roller is rotatably mounted on the slitting bracket to further compact the film material strip and the base material strip.

[0010] Furthermore, at least two groups of heating workbenches are provided on the frame, and the material receiving mechanism cooperates with the heating workbenches to perform intermittent winding.

[0011] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the card bag making machine of the present invention heats the hot-melt adhesive strip through the film through the pressure strip to make the film and the base layer directly adhere to each other into a bag body, so that the bag body can achieve the effect of different functions on both sides, and has high applicability. The film material strip and the base material strip can be made of various materials to achieve different functions; the bag making machine of the present invention directly makes bags on a heated workbench without folding the material strip into a tube, which is beneficial to reducing equipment costs and improving production efficiency.
