Description

Technical Field

[0001] This utility model relates to the field of open bag processing technology, and in particular to a cutting device for open bags. Background Technology

[0002] In the packaging industry, open bags are a common packaging form, widely used in food, chemical, building materials and other fields.

[0003] In the production process of open bags, cutting and sealing are two key steps that directly affect the quality of the bag and production efficiency. Traditional cutting devices usually adopt a fixed design, and the cutting length is not adjustable. This means that when producing open bags of different specifications, it is necessary to change equipment or make complex adjustments. At the same time, the sealing work is carried out separately after the open bags are cut, which reduces the processing efficiency. Therefore, we propose a cutting device for open bags.

Detailed Implementation

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] This utility model provides, for example Figures 1-3 A cutting device for an open bag is shown.

[0041] Example 1 includes a workbench 101, a cutting mechanism, an adjusting mechanism, a pressing mechanism, and a hot pressing mechanism. The cutting mechanism is located above the workbench 101. The adjusting mechanism is connected to the cutting mechanism and is used to change the position of the cutting mechanism. The pressing mechanism is used to position the open bag at the top of the workbench 101. The hot pressing mechanism is used to seal one side of the open bag. The pressing mechanism positions the bag at the top of the workbench 101. Then, the cutting mechanism and the hot pressing mechanism work simultaneously. The cutting mechanism processes the opening position of the open bag, and the hot pressing mechanism processes the bottom position of the open bag, thereby improving the convenience and efficiency of open bag processing. At the same time, with the cooperation of the adjusting mechanism, the cutting mechanism can produce open bags of different lengths, thereby improving the applicability of the cutting mechanism.

[0042] The cutting mechanism includes a blade holder 201 and a cutting blade 202. The blade holder 201 is connected to the adjustment mechanism. The cutting blade 202 is installed at the bottom of the blade holder 201. The cutting blade 202 is moved down by the blade holder 201, so that the cutting blade 202 comes into contact with the bag body and the cutting work can be carried out.

[0043] The adjustment mechanism includes a lifting seat 301 and a slider 302. The top of the lifting seat 301 is equipped with a lifting mechanism, and the bottom of the lifting seat 301 is provided with a groove 303. The outer wall of the slider 302 is slidably connected to the inner wall of the groove 303, and the bottom of the slider 302 is fixedly connected to the top of the cutter holder 201. By moving the slider 302 in the groove 303, the position of the cutter holder 201 can be adjusted, thereby achieving the effect of changing the cutting position.

[0044] The inner wall of the slide groove 303 is provided with a lead screw 304, and a threaded hole 305 is provided on one side of the slider 302. The outer wall of the lead screw 304 is threadedly connected to the inner wall of the threaded hole 305. One end of the lead screw 304 passes through the inner wall of the slide groove 303 and is fixedly connected to a knob 401. By rotating the lead screw 304 and engaging the threaded connection between the outer wall of the lead screw 304 and the inner wall of the threaded hole 305, the lead screw 304 can rotate and drive the slider 302 to move within the slide groove 303. The knob 401 makes it easy to rotate the lead screw 304, thereby improving the convenience of the adjustment mechanism.

[0045] The lifting mechanism includes an inverted U-shaped frame 501 and a hydraulic cylinder 502. The inverted U-shaped frame 501 is fixedly connected to the top of the workbench 101. The lifting seat 301 is located inside the inverted U-shaped frame 501. The hydraulic cylinder 502 is installed on the top of the inverted U-shaped frame 501. The output end of the hydraulic cylinder 502 is connected to the top of the lifting seat 301. The lifting seat 301 can be lifted and lowered by the operation of the hydraulic cylinder 502. The hydraulic cylinder 502 is electrically connected to an external power supply through an external switch, which facilitates the operator to control the hydraulic cylinder 502 and improves the safety and convenience of operating the hydraulic cylinder 502.

[0046] In Embodiment 2, compared to Embodiment 1, the pressing mechanism includes a pressing block 601 and a rubber pad 602. A connecting mechanism is provided between the pressing block 601 and the lifting seat 301. The rubber pad 602 is attached to the bottom end of the pressing block 601. When the lifting seat 301 descends, it will cause the pressing block 601 to descend until the rubber pad 602 abuts against the bag body at the top of the workbench 101, thereby positioning the bag body and ensuring that the bag body can be stably cut and heat-pressed. At the same time, the setting of the rubber pad 602 avoids damage to the bag body.

[0047] The connecting mechanism includes a fixed block 603, a connecting rod 605, a limiting block 607, and a spring 608. The top end of the fixed block 603 is fixedly connected to the bottom end of the lifting seat 301, and the bottom end of the connecting rod 605 is fixedly connected to the top end of the pressure block 601. A movable hole 604 is provided at the bottom end of the fixed block 603. The outer wall of the connecting rod 605 is movably inserted into the inner wall of the movable hole 604. A limiting cavity 606 is provided in the inner wall of the movable hole 604. The bottom end of the limiting block 607 is connected to the connecting rod 608. The top of 605 is fixedly connected, the outer wall of the limiting block 607 is slidably connected to the inner wall of the limiting cavity 606, and the spring 608 is set above the limiting block 607. When the lifting seat 301 descends and drives the pressure block 601 to descend, so that the rubber pad 602 contacts the bag body, the cutting mechanism and the hot pressing mechanism are not yet in place. At this time, the lifting seat 301 continues to move down, and the limiting block 607 will move up in the limiting cavity 606 to squeeze the spring 608 until the cutting mechanism and the hot pressing mechanism work.

[0048] In Example 3, compared to Example 2, the hot pressing mechanism includes a connecting block 701, a first hot pressing block 702, and a second hot pressing block 703. The top end of the connecting block 701 is fixedly connected to the bottom end of the lifting seat 301. The first hot pressing block 702 is installed at the bottom end of the connecting block 701. An installation groove is provided at the top end of the workbench 101. The second hot pressing block 703 is installed inside the installation groove. The first hot pressing block 702 and the second hot pressing block 703 are positioned opposite each other. When the bag is at the top of the workbench 101, it is located between the open bag body and the connecting block 701 and the second hot pressing block 703. Then, the lifting seat 301 descends, causing the connecting block 701 to descend until the first hot pressing block 702 abuts against the bag body. At this time, the first hot pressing block 702 and the second hot pressing block 703 are powered on to heat press the bag body, thereby sealing the bag body on one side to obtain an open bag.
