Description

Technical Field

[0001] This utility model relates to the technical field of packaging equipment, specifically, a double-row three-side sealing cat strip packaging machine. Background Technology

[0002] In the existing technology, during the packaging process of a vertical packaging machine, the packaging film first needs to be conveyed out and then cut into multiple strips so that the multiple strips of packaging film are formed into bags by the bag maker, and then sealed using the longitudinal sealer and the transverse sealer.

[0003] However, in existing film cutting and slitting mechanisms of packaging machines, multiple circular cutters are usually installed on vertically distributed cutting shafts. The packaging film is then transported between these shafts and cut by the circular cutters. However, this type of cutting device is generally only suitable for multi-row packaging machines. In small double-row packaging machines, the cutting device is relatively complex because the circular cutters are individually sleeved on the cutting shafts. During maintenance, the entire cutting shaft needs to be disassembled to replace the circular cutters, and the gap between the corresponding vertical circular cutters also needs to be adjusted, making the operation quite cumbersome. Utility Model Content

[0004] In order to overcome the defects of the existing technology, this utility model provides a double-row three-side sealing cat strip packaging machine to solve the problems in the existing technology.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a double-row three-side sealing cat strip packaging machine, which has a machine body, two collar forming devices are arranged in the machine body, and a dividing film assembly is arranged in the upstream direction of the two collar forming devices.

[0006] The segmented membrane assembly includes a central shaft, both ends of which are mounted in the machine body via mounting plates. A first guide roller and a second guide roller are arranged side by side on the central shaft, with a cutting gap between them. A cutter fixing rod is provided on one side of the central shaft, with both ends of the cutter fixing rod mounted in the machine body. A circular cutter is mounted on the cutter fixing rod via a cutter seat, and part of the circular cutter is located within the cutting gap.

[0007] The aforementioned double-row three-side sealing cat strip packaging machine also includes:

[0008] An unwinding shaft is used to unwind the packaging film. Above the unwinding shaft is a set of guide rollers mounted on the machine body. The segmented film assembly is located between the guide rollers and the collar forming device.

[0009] Two longitudinal sealers are provided, with the two longitudinal sealers located below the two lapel forming devices;

[0010] The horizontal sealer is located below the vertical sealer;

[0011] The bag cutter is located below the horizontal sealer.

[0012] In the above-mentioned double-row three-side seal cat strip packaging machine, a material tube is installed inside the collar forming device. A feed pipe and a blocking pipe are connected at the upper end of the material tube. A blocking cylinder is installed on the blocking pipe. A storage hopper is installed at the upper end of the machine body. The storage hopper is connected to the feed pipe. The blocking cylinder is used to open or close the channel between the feed pipe and the material tube.

[0013] In the above-mentioned double-row three-side sealing cat strip packaging machine, the cylinder shaft of the blocking cylinder is located inside the blocking tube, and a blocking head is installed at the end of the cylinder shaft of the blocking cylinder.

[0014] In the aforementioned double-row three-side-seal cat strip packaging machine, the bag cutter includes a fixed base installed inside the machine body. Two movable receiving boxes are provided on one side of the fixed base. A vertical channel is provided inside the receiving box. A cutter cylinder seat is provided at the lower end of the fixed base. Two cutter cylinders are provided on the cutter cylinder seat. The cylinder shafts of the two cutter cylinders are equipped with cutters. The cutters are located below the receiving boxes.

[0015] In the above-mentioned double-row three-side sealing cat strip packaging machine, a box frame is provided on the side of the receiving box, and a strip-shaped hole is opened on the box frame. The receiving box is connected to the strip-shaped hole by connecting bolts, and the box frame is connected to the fixed base.

[0016] The beneficial effects of this utility model are as follows: by placing part of the circular cutter body inside the cutting gap, and the first guide roller and the second guide roller being coaxially arranged and only used for guiding or conveying the packaging film, the packaging film can be directly cut by the circular cutter. The structure is simpler than the traditional upper and lower distributed cutter structure, and is more suitable for double-row packaging machines. Moreover, the maintenance process of the cutter body does not require the removal of multiple shafts. The circular cutter can be directly disassembled and assembled on the cutter seat, making maintenance more convenient and operation simpler. Attached Figure Description

[0021] Combination Figure 1 and Figure 2 The illustrated double-row three-side-seal cat strip packaging machine has a body 1. Two collar forming devices 4 are installed inside the body 1, and a dividing film assembly is positioned upstream of each collar forming device 4. This assembly divides the packaging film into two halves, which are then fed onto the corresponding collar forming devices 4 to form a bag shape. The dividing film assembly includes a central shaft 11, with both ends of the central shaft 11 mounted inside the body 1 via mounting plates 14. A first guide roller 12 and a second guide roller 13 are arranged side-by-side on the central shaft 11, with a cutting gap between them. A cutter fixing rod 15 is located on one side of the central shaft 11, with both ends of the cutter fixing rod 15 installed inside the body 1. A cutter seat 16 is positioned on the cutter fixing rod 15. A circular cutter 17 is installed, with part of the blade body located within the cutting gap. In this embodiment, the first guide roller 12 and the second guide roller 13 are coaxially arranged and are only used for guiding or conveying the packaging film, allowing the packaging film to be directly cut by the circular cutter 17. The structure is simpler than the traditional top-and-bottom distributed cutter structure and is more suitable for double-row packaging machines. Moreover, the maintenance process of the blade body does not require the removal of multiple shafts, and the circular cutter 17 can be directly installed and removed on the cutter holder 16, making maintenance more convenient and operation simpler.

[0022] In some embodiments, the center of the circular cutter 17 is bolted to the side of the cutter holder 16, making disassembly and assembly simpler. Furthermore, the cutter fixing rod 15 can be rotatably mounted inside the machine body 1 to adjust the depth of the circular cutter 17 within the cutting gap.

[0023] The double-row three-side seal cat strip packaging machine of this embodiment also includes: an unwinding shaft 2, a longitudinal sealer 5, a transverse sealer 8, and a bag cutter 9. The unwinding shaft 2 is used to unwind the packaging film. A guide roller group 3 installed on the machine body 1 is arranged above the unwinding shaft 2. The guide roller group 3 is provided with multiple layers of guide rollers for guiding the winding and conveying of the packaging film. The dividing film assembly is located between the guide roller group 3 and the collar forming device 4. There are two longitudinal sealers 5, which are located below the two collar forming devices 4. The transverse sealer 8 is located below the longitudinal sealers 5. The bag cutter 9 is located below the transverse sealer 8 and is used to cut the sealed bag into individual bags.

[0024] It is worth noting that the longitudinal sealer 5 and the transverse sealer 8 in this embodiment are both existing technologies, and their structures will not be described in detail.

[0025] In this embodiment, the collar forming machine 4 has a material pipe 7 inserted inside. The upper end of the material pipe 7 is connected to a feed pipe and a blocking pipe. A blocking cylinder 6 is installed on the blocking pipe. A storage hopper 10 is installed on the upper end of the machine body 1, and the storage hopper 10 is connected to the feed pipe. The blocking cylinder 6 is used to open or close the channel between the feed pipe and the material pipe 7. It is worth noting that in this embodiment, the cylinder shaft of the blocking cylinder 6 is located inside the blocking pipe, and a blocking head is installed at the end of the cylinder shaft. Material from the storage hopper 10 is fed into the material pipe 7 through the feed pipe, allowing the material to fall into the bag body through the material pipe 7. Under the action of the blocking cylinder 6, after the material has fallen, the channel between the feed pipe and the material pipe 7 can be closed to prevent accidental material leakage during the sealing process.

[0026] like Figure 3 As shown, the bag cutter 9 in this embodiment includes a fixed base 18 installed inside the machine body 1. Two movable receiving boxes 20 are provided on one side of the fixed base 18. A vertical channel is provided inside the receiving box 20. A cutter cylinder seat 22 is provided at the lower end of the fixed base 18. Two cutter cylinders 23 are provided on the cutter cylinder seat 22. Each of the cylinder shafts of the two cutter cylinders 23 is equipped with a cutter 24. The cutter 24 is located below the receiving box 20. This allows multiple bags that have been sealed and are connected in a line to enter the vertical channel inside the receiving box 20, preventing shaking. Then, the cutter cylinders 23 drive the cutter 24 to cut the bags coming out of the vertical channel, resulting in a more accurate cut.

[0027] The side of the container 20 in this embodiment is provided with a frame 19, and the frame 19 has a strip hole 21. The container 20 is connected to the strip hole 21 by connecting bolts, and the frame 19 is connected to the fixing base 18. This allows the position of the container 20 to be adjusted, and the spacing of the bags coming out of the vertical channel can be adjusted to prevent the cutter from hitting the cutter when cutting.

[0028] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
