Description

Technical Field

[0001] This utility model relates to the field of woven bag production technology, specifically to a bag cutting machine for woven bag processing and production. Background Technology

[0002] Woven bags, also known as snake-skin bags, are a type of plastic bag used for packaging. They are typically made from various chemical plastics such as polyethylene and polypropylene. Woven bags have a wide range of applications in industrial and agricultural product packaging, food packaging, and tourism transportation, and are also indispensable engineering materials and flood control supplies. After woven bags are produced, they need to be cut. Some existing bag-cutting devices are prone to over-cutting, leading to inaccurate cuts, wrinkles, uneven cuts, and difficulties in collecting the material after unloading.

[0003] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content

[0004] This utility model proposes a bag cutting machine for woven bag processing and production, which solves the problems of existing bag cutting devices in related technologies, such as over-cutting, resulting in inaccurate cutting, wrinkles easily appearing during cutting leading to uneven cuts, and inconvenience in collecting the material during unloading.

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0028] like Figures 1-4 As shown, this embodiment proposes a bag cutting machine for woven bag processing and production, including...

[0029] A processing table 1 and a top frame 2, wherein the top frame 2 is fixed to the surface of the processing table 1;

[0030] Correction component 5, the correction component 5 being disposed on the surface of the processing table 1;

[0031] The unloading component 6 is disposed at one end of the surface of the processing table 1;

[0032] A pair of conveyor rollers 3 are mounted on the surface of the processing table 1 and located on both sides of the top frame 2. The conveyor rollers 3 are driven to rotate by a motor.

[0033] A clamping and cutting assembly 4 is disposed inside the processing table 1 and the top frame 2. The clamping and cutting assembly 4 includes a pair of through cavities 4-1, which are formed at both ends of the top frame 2. A vertical screw 4-2 is rotatably connected to each through cavity 4-1, and a round rod 4-3 is fixedly connected to each through cavity 4-1. A cross frame 4-4 is slidably fitted onto the outside of the round rod 4-3. The cross frame 4-4 is threadedly connected to the vertical screw 4-2. The bottom of the cross frame 4-4... The movable assembly is connected to a pair of pressure plates 4-5. A spring 4-6 is connected between the pressure plates 4-5 and the crossbar 4-4. A transmission wheel 4-7 is installed on the upper end of the vertical screw 4-2. A drive motor 4-8 is installed on the top of the top frame 2. The output end of the drive motor 4-8 is connected to the vertical screw 4-2. A telescopic cylinder 4-9 is installed on the surface of the top frame 2. A cutting blade 4-10 is connected to the output end of the telescopic cylinder 4-9. The bottom of the cutting blade 4-10 passes through the crossbar 4-4.

[0034] In this embodiment, in order to achieve the anti-wrinkle and anti-shift cutting effect on the woven bag, a pressing and cutting component 4 is designed. Round rods 4-3 and vertical screws 4-2 are provided on both sides of the top frame 2. The two vertical screws 4-2 rotate synchronously through the transmission wheel 4-7 at the top, which can drive the horizontal frame 4-4 on the surface to move vertically up and down. At the bottom of the horizontal frame 4-4, a pressure plate 4-5 is connected to the bottom through a spring 4-6. When the horizontal frame 4-4 descends, it can be pressed against the surface of the woven bag by the pressure plate 4-5. A telescopic cylinder 4-9 is provided in the center of the top frame 2 and a cutting blade 4-10 is connected to the output end. The woven bag can be cut vertically downward by the cutting blade 4-10. With the help of the pressure plate 4-5, wrinkles and shifting will not occur.

[0035] Furthermore, the correction component 5 includes a groove 5-1, which is formed on the surface of the processing table 1. A side plate 5-2 is fixedly connected to the surface of the processing table 1. A second cylinder 5-3 is installed on the side surface of the side plate 5-2. The output end of the second cylinder 5-3 is connected to a limit plate 5-4.

[0036] In this embodiment, in order to achieve a certain corrective effect during the conveying of woven bags, a corrective component 5 is designed. Side plates 5-2 are installed on both sides of the surface of the processing table 1, and a limiting plate 5-4 is connected to the surface of the side plates 5-2 through a second cylinder 5-3. The limiting plate 5-4 is pressed against both sides of the woven bag to facilitate position adjustment.

[0037] Furthermore, the unloading assembly 6 includes a notch 6-1, which is formed on the surface of the processing table 1. An unloading plate 6-2 is rotatably connected inside the notch 6-1. A pair of bottom rods 6-3 are fixedly connected to the bottom surface of the processing table 1. A third cylinder 6-4 is rotatably connected between the bottom rods 6-3 and the unloading plate 6-2 via a pin.

[0038] In this embodiment, in order to quickly discharge the cut woven bags, a feeding assembly 6 is designed. A notch 6-1 is opened on one side of the processing table 1 and a feeding plate 6-2 is rotatably connected inside. The feeding plate 6-2 can be flipped downwards. A third cylinder 6-4 is rotatably connected to the feeding plate 6-2 at the bottom of the processing table 1 via a bottom rod 6-3. The feeding plate 6-2 can be pulled downwards by the output end of the third cylinder 6-4, which can quickly discharge the woven bags.

[0039] Furthermore, the limiting plate 5-4 is bent inward at both ends with a certain tilt angle.

[0040] In this embodiment, the inward bending angle allows the limiting plate 5-4 to slide and fit against the woven bag without being stuck at the edge.

[0041] Furthermore, the transmission wheels 4-7 are connected by a belt drive.

[0042] In this embodiment, the transmission wheel 4-7 drives the two vertical screws 4-2 to rotate synchronously through the belt drive, so that the cross frame 4-4 can be raised and lowered smoothly.

[0043] Furthermore, the feed plate 6-2 can be rotated downwards by 45-60° through the rotatable connection with the notch 6-1.

[0044] In this embodiment, a sufficient tilt angle is used to allow the woven bag to slide downwards without obstruction.

[0045] Furthermore, the groove 5-1 has a larger opening size than the horizontal length of the limiting plate 5-4.

[0046] In this embodiment, the groove 5-1 ensures that the surface of the limiting plate 5-4 is flush with the surface of the processing table 1, without any gaps, thus preventing the woven bag from getting stuck in the gaps.

[0047] When bag cutting is required, adjust the distance between the two limit plates 5-4 according to the size of the woven bag, and then send it to the bottom of the infeed roller 3. Start the conveyor roller 3 to move the woven bag to the cutting position. Start the drive motor 4-8 to make the two transmission wheels 4-7 rotate synchronously to drive the vertical screw 4-2, so that the cross frame 4-4 moves vertically downward. Through the elastic force of the pressure plate 4-5 and the spring 4-6, it is pressed against the surface of the woven bag. Then, start the telescopic cylinder 4-9 to drive the cutting knife 4-10 to quickly cut the woven bag. Then lift the pressure plate 4-5 and start the two conveyor rollers 3 at the same time. The cut woven bag moves to the surface of the feed plate 6-2. At the same time, adjust the next cutting position and start the third cylinder 6-4 at the bottom. The third cylinder 6-4 pulls the feed plate 6-2 down to make the woven bag slide down.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
