Description

Technical Field

[0001] This utility model relates to the field of bag making technology, and in particular to a bag making die-cutting device. Background Technology

[0002] In online bag manufacturing processes, roll materials such as plastic films and other composite materials can be cut into bags of specific shapes and sizes using a die-cutting machine. After die-cutting, the film will produce "ear" material at the sealing edge of the bag. This can easily lead to incomplete cutting, causing the ear material to stick to the sealing edge, thus affecting the normal collection of ear material and the transfer of finished bags. It can even affect the cutting quality of the finished bag, causing die-cutting disorder and affecting cutting efficiency. Utility Model Content

[0026] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1 As shown, the present invention provides a bag making die-cutting device, including a die-cutting mechanism 1, a support plate 2, a conveyor roller 3, a conveyor belt 4, a base plate 5, a material transfer assembly 7, and a material separator 8. The die-cutting mechanism 1 is located between the support plate 2 and the conveyor belt 4.

[0028] like Figure 2-3 As shown, the die-cutting mechanism 1 includes a frame 11, a pressure plate 12, a cutter 15, and a first driving member 17. The first driving member 17 is connected inside the frame 11 and is connected to the pressure plate 12. The bottom of the pressure plate 12 is provided with the cutter 15.

[0029] The frame 11 is equipped with a guide rod 18, which is connected to the pressure plate 12. The first driving component 17 is an existing cylinder that drives the pressure plate 12 to rise and fall. The guide rod 18 plays a guiding role to prevent the pressure plate 12 from being misaligned and affecting the bag cutting position.

[0030] The die-cutting mechanism 1 also includes a connecting plate 13. The cutter 15 is connected to the pressure plate 12 via the connecting plate 13, and the connecting plate 13 is connected to the pressure plate 12 via a first fastener 16. The arrangement and size of the cutter 15 can be pre-made on the connecting plate, so that the matching connecting plate 13 can be quickly installed via the first fastener 16 according to the size of the cut finished bag body 9.

[0031] The connecting plate 13 is provided with a stop bar 14, which is arranged on both sides of the cutter 15, and the cutting part of the cutter 15 extends out of the stop bar 14. The stop bar 14 can protect the cutter 15 and prevent the cutter 15 from becoming skewed after repeated cutting, thus affecting the cutting quality.

[0032] like Figure 4 As shown, the base plate 5 is located above the support plate 2 and below the cutter 15. After edge sealing, the film material 6, which is conveyed online, enters the die-cutting mechanism 1 from the base plate 5 for cutting. The base plate 5 plays a supporting role, so that the film material 6 remains flat when it comes into contact with the cutter 15, and also avoids the film material 6 from sagging or wrinkling when entering the die-cutting mechanism 1, which would affect the accuracy of the cutting position.

[0033] The support plate 2 is provided with a connecting groove 21. The connecting groove 21 is connected to a positioning plate 22 through a second fastener 23. The positioning plate 22 presses against the side of the base plate 5 and plays a positioning role for the base plate 5 to prevent the base plate 5 from shifting. Since the base plate 5 is in frequent contact with the cutter 15, the second fastener 23 also facilitates the replacement of the base plate 5.

[0034] like Figure 5 As shown, the conveyor roller 3 is located between the conveyor belt 4 and the die-cutting mechanism 1, and the conveyor roller 3 is provided with a second driving member 31; the material transfer assembly 7 is located above the conveyor roller 3, and the material transfer assembly 7 includes a third driving member 71 and a driven roller 72, with the third driving member 71 connected to the driven roller 72.

[0035] The second driving component 31 is an existing motor, which drives the conveyor roller 3 to rotate continuously. The cut bag body 9 is transferred from the conveyor roller 3. The third driving component 71 can be a cylinder, which cooperates with the die-cutting mechanism 1 to control the lifting and lowering of the driven roller 72. The bag body 9 is transferred between the driven roller 72 and the conveyor roller 3, and is quickly transferred to the conveyor belt 4. Compared with only the conveyor roller 3, the driven roller 72 presses on the bag body 9 for auxiliary transfer, which can speed up the transfer of the bag body 9 and control the transfer direction of the bag body 9, preventing the bag body 9 from falling out of the gap between the conveyor roller 3 and the conveyor belt 4.

[0036] The material transfer assembly 7 also includes a mounting plate 73, a slider 75, and a third fastener 76. The mounting plate 73 has a mounting groove 74, and the slider 75 is connected to the mounting groove 74 via the third fastener 76. The third drive component 71 is connected to the slider 75. Depending on the different transport positions of the bags 9, the position of the slider 75 in the mounting groove 74 can be adjusted via the third fastener 76. The number of driven rollers 72 can also be increased according to the number of bags 9.

[0037] Several partition plates 8 are arranged side by side on the conveyor belt 4. The ends of the partition plates 8 are provided with ear material positioning parts 81. The ear material positioning parts 81 are close to the roller surface of the conveyor roller 3 and face the discharge end of the die-cutting mechanism 1. The ear material 91 generated after cutting the bag body 9 is conveyed along the conveyor roller 3 to the ear material collection device for unified collection and recycling. The ear material positioning parts 81 can scrape off and position the ear material 91 on the edge of the bag body 9, preventing the ear material 91 from sticking to the edge of the bag body 9, causing ear material entanglement and other abnormal phenomena, which would affect the normal transmission of the bag body 9.

[0038] The bags 9 on the conveyor belt 4 are transported one by one between the partition plates 8, facilitating the subsequent collection and packaging of the bags 9. Figure 6 As shown, the partition plate 8 is provided with a connecting rod 82 and a connecting ring 83. The fourth fastener 84 is connected to the connecting rod 82 through the connecting ring 83. According to the size of the bag body 9, the position of the partition plate 8 can be quickly adjusted by the fourth fastener 84 to adjust the positioning position of the ear material 91 and the partition position of the bag body 9.

[0039] This utility model discloses a bag-making die-cutting device. The sealed film 6 is conveyed online to the base plate 5 and then enters the die-cutting mechanism 1. The die-cutting mechanism 1 cuts the film 6, and the cut bags are conveyed one by one from the driven roller 72 and the conveyor roller 3 onto the conveyor belt 4. Figure 7As shown, after the sealing edge 92 of the finished bag body 9 is cut, ear material 91 will be generated on the side. The ear material 91 is positioned and guided to the existing ear material collection device by the separator plate 8. The operation of the third drive member 71 and the first drive member 17 is adapted to the speed of the online transmission of the membrane 6.

[0040] The preferred embodiments of this utility model have been described in detail above, but this utility model is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
