Description

Technical Field

[0001] This utility model relates to the field of bag making machine technology, specifically to a high-speed bag making machine with a transmission roller. Background Technology

[0002] A high-speed bag-making machine is a device used to quickly produce various types of plastic or paper bags. It manufactures packaging bags made of various plastic or other materials, with a processing range including bags of different sizes and thicknesses. Generally, plastic packaging bags are the primary product. These machines are commonly used to produce food packaging bags, pharmaceutical packaging bags, cosmetic bags, and everyday item bags.

[0003] Currently, the conveying mechanism of the bag making machine is larger than the size of the material roll to accommodate material rolls of different sizes. However, when replacing the material roll in the bag making machine, the position of the previous material roll needs to be considered to make the new material roll correspond to the previous material roll, which is quite troublesome and affects the material changing efficiency of the bag making machine. There is an urgent need to design a high-speed bag making machine with a drive roller to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-speed bag-making machine with a drive roller to overcome the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-speed bag making machine with drive rollers includes a support platform, a fixed frame and a bracket mounted on the top of the support platform, a hot cutting mechanism disposed within the fixed frame, an inclined slide corresponding to the fixed frame mounted on one side of the support platform for collecting the cut packaging bags, two drive rollers rotatably fitted within the bracket, a motor mounted on one side of the bracket with its output end connected to one of the drive rollers, a slide rail disposed on one side of the bracket, a movable rod slidably fitted within the slide rail, and a sealing device mounted at the bottom of the movable rod.

[0007] A fixed frame is installed on one side of the support platform. A rotating rod is rotatably fitted inside the fixed frame. A loading rod is installed on both sides of the rotating rod. A fixing component is provided at one end of the loading rod. A limiting plate is slidably fitted on the periphery of the rotating rod and the periphery of the two loading rods. A fixing bolt corresponding to the rotating rod is provided on the limiting plate.

[0008] Furthermore, the hot cutting mechanism includes a cylinder mounted on the top of the fixed frame, a movable seat slidably fitted within the fixed frame, and a hot melt blade mounted on the bottom of the movable seat. The top of the movable seat is connected to the output end of the cylinder, and a cutting groove corresponding to the hot melt blade is formed on the bottom of the inner wall of the fixed frame.

[0009] Furthermore, fixing blocks are installed on both the front and rear sides of the movable seat, and a sliding rod is slidably fitted inside the fixing block. A pressure rod is installed at the bottom end of the sliding rod, and a first spring is provided between the top end of the sliding rod and the top of the fixing block.

[0010] Furthermore, the inner wall of the bracket is provided with sliding grooves on both opposite sides, and sliders are slidably fitted in the sliding grooves. One of the transmission rollers is rotatably fitted between the two sliders. A pull rod is installed on the top of the slider, and a second spring is sleeved on the periphery of the pull rod. The top of the pull rod passes through the top of the bracket.

[0011] Furthermore, the circumference of the feeding rod is fitted with multiple rotating rings, which are used for the material roll to rotate around the circumference of the feeding rod.

[0012] Furthermore, the fixing component includes a storage groove formed at one end of the loading rod, two retaining plates rotatably fitted in the storage groove, the two retaining plates being symmetrically arranged, a movable rod elastically fitted at one end of the loading rod, and connecting rods rotatably fitted on both sides of the movable rod, with one end of each of the two connecting rods rotatably fitted to one side of the two retaining plates respectively.

[0013] In the above technical solution, the high-speed bag making machine with a transmission roller provided by this utility model has the following advantages:

[0014] The fixed components and limiting plates allow for adjustment of the limiting plate's position to accommodate material rolls of different sizes. This allows the material roll to pass through the fixed components and fit around the loading rod, ensuring that the newly replaced material roll corresponds to the previous one. This enables quick material roll installation and improves material change efficiency. The rotating rod allows for rotation, which in turn moves the two loading rods, allowing the new material roll to be installed on the rear loading rod. Rotating the rotating rod enables quick material changes and reduces the hassle of changing materials. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-5 As shown in the figure, this utility model embodiment provides a high-speed bag making machine with a transmission roller.

[0024] The system includes a support platform 1, a fixed frame 2 and a bracket 5 mounted on the top of the support platform 1, a hot cutting mechanism 3 installed inside the fixed frame 2, an inclined slide 4 corresponding to the fixed frame 2 installed on one side of the support platform 1, the inclined slide 4 is used to collect the cut packaging bags, two drive rollers 6 are rotatably fitted inside the bracket 5, a motor 7 is installed on one side of the bracket 5, the output end of the motor 7 is connected to one of the drive rollers 6, a slide rail 8 is provided on one side of the bracket 5, a movable rod 9 is slidably fitted inside the slide rail 8, and an edge sealer 10 is installed at the bottom of the movable rod 9.

[0025] A fixed frame 11 is installed on one side of the support platform 1. A rotating rod 12 is rotatably fitted inside the fixed frame 11. A loading rod 13 is installed on both sides of the rotating rod 12. A fixing component 14 is provided at one end of the loading rod 13. A limiting plate 15 is slidably fitted on the periphery of the rotating rod 12 and the periphery of the two loading rods 13. A fixing bolt 16 corresponding to the rotating rod 12 is provided on the limiting plate 15.

[0026] Reference Figure 2 The hot-cutting mechanism 3 in this embodiment includes a cylinder 17 mounted on the top of the fixed frame 2, a movable seat 18 slidably fitted within the fixed frame 2, and a hot-melt blade 19 mounted on the bottom of the movable seat 18. The top of the movable seat 18 is connected to the output end of the cylinder 17. A cutting groove 20 corresponding to the hot-melt blade 19 is provided on the bottom of the inner wall of the fixed frame 2. The cylinder 17 can drive the movable seat 18 to move downward, which in turn drives the hot-melt blade 19 downward, allowing the hot-melt blade 19 to cut the packaging bag. The cutting groove 20 protects the hot-melt blade 19 and reduces the chance of it colliding with other parts of the packaging bag.

[0027] Reference Figure 2 In this embodiment, fixed blocks 21 are installed on both the front and rear sides of the movable seat 18. A sliding rod 22 is slidably fitted inside the fixed block 21. A pressure rod 23 is installed at the bottom end of the sliding rod 22. A first spring 24 is provided between the top end of the sliding rod 22 and the top of the fixed block 21. When the movable seat 18 moves downward, it will drive the fixed block 21 to move downward, causing the fixed block 21 to drive the sliding rod 22 and the pressure rod 23 to move downward. This causes the two pressure rods 23 to press and fix the packaging bag. The sliding rod 22 will slide inside the fixed block 21 and press the first spring 24, allowing the hot melt knife 19 to cut the packaging bag. When the hot melt knife 19 rises, the pressure rod 23 continues to press and fix the packaging bag to prevent the hot melt knife 19 from sticking to the packaging bag. Then, the first spring 24 will drive the sliding rod 22 and the pressure rod 23 to return to their original positions.

[0028] Reference Figure 3 In this embodiment, the inner wall of the bracket 5 has grooves 25 on both opposite sides. Sliding blocks 26 are slidably fitted within the grooves 25. One transmission roller 6 is rotatably engaged between the two sliding blocks 26. A pull rod 27 is mounted on the top of the sliding blocks 26, and a second spring 28 is sleeved around the periphery of the pull rod 27. The top of the pull rod 27 passes through the top of the bracket 5. By pulling the sliding blocks 26, the pull rod 27 can be pulled, causing the sliding blocks 26 to move upwards along the grooves 25. The movement of the sliding blocks 26 causes the transmission rollers 6 to move upwards, allowing the packaging bag to pass between the two transmission rollers 6. Releasing the pull rod 27 causes the second spring 28 to compress the sliding blocks 26 downwards, causing the two transmission rollers 6 to compress the packaging bag. The motor 7 drives one of the transmission rollers 6 to rotate, thus conveying the packaging bag.

[0029] Reference Figure 4 In this embodiment, the feeding rod 13 is rotatably fitted with multiple rotating rings 29. The rotating rings 29 are used for the material roll to rotate around the feeding rod 13. Through the rotating rings 29, the material roll can be fitted onto the feeding rod 13, so that the material roll contacts the circumference of the rotating rings 29. When the material roll rotates and is released along the circumference of the feeding rod 13, the material roll can drive the rotating rings 29 to rotate.

[0030] Reference Figure 5 The fixing component 14 in this embodiment includes a receiving groove 30 at one end of the loading rod 13 and two clamping plates 31 rotatably engaged within the receiving groove 30. The two clamping plates 31 are symmetrically arranged. A moving rod 32 is elastically engaged at one end of the loading rod 13, and connecting rods 33 are rotatably engaged on both sides of the moving rod 32. One end of each of the two connecting rods 33 is rotatably engaged with one side of each of the two clamping plates 31. When installing the material roll, the clamping plates 31 can push the two clamping plates 31 into the receiving groove 30, allowing the material roll to be installed around the periphery of the loading rod 13. The two clamping plates 31 can fix the material roll when they are spread out. Pressing the moving rod 32 can move the moving rod 32 to pull the two connecting rods 33, causing the connecting rods 33 to pull the clamping plates 31 to rotate. The rotating clamping plates 31 will enter the receiving groove 30, releasing the fixation of the material roll. The elastic engagement of the moving rod 32 can drive the clamping plates 31 to open and reset.

[0031] Working principle: In use, the material roll is first installed on the loading rod 13, and then the position of the limiting plate 15 is adjusted so that the limiting plate 15 and the fixing component 14 position the material roll. Then, the rotating rod 12 can be moved to drive the loading rod 13 to move so that the loading rod 13 corresponds to the transmission roller 6. The position of the sealing device 10 is adjusted as needed so that the movable rod 9 moves along the slide rail 8 so that the sealing device 10 seals the material. Then, the material in the material roll passes through the two transmission rollers 6. The motor 7 is started to drive one of the transmission rollers 6 to rotate so that the transmission roller 6 conveys the material to the fixed frame 2. The hot cutting mechanism 3 in the fixed frame 2 will cut the material to complete the bag making. The finished packaging bag will enter the inclined slide 4.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
