Description

Technical Field

[0001] This utility model relates to the field of packaging bag processing technology, specifically a cutting device for packaging bag processing. Background Technology

[0002] In the packaging bag manufacturing process, cutting is a crucial step in dividing the bag-making raw materials (such as plastic film, composite film, etc.) into preset sizes and shapes, directly affecting the final dimensional accuracy, edge smoothness, and subsequent processing efficiency of the packaging bags. Traditional packaging bag cutting devices mostly use manual feeding combined with fixed cutting tools, which not only suffers from high labor intensity and low production efficiency, but is also prone to inconsistent cutting sizes due to human error, resulting in material waste.

This structure facilitates the cutting of packaging bags by workers, achieving a high degree of automation. It eliminates the need for workers to flatten and fix the packaging bags during cutting, automatically flattening and fixing them, preventing edge curling, and resulting in better cutting performance. However, a drawback is that the device lacks a braking mechanism for fixing and raising / lowering the device during cutting. This means that the device does not provide corresponding adjustment assistance during processing, hindering more efficient cutting operations. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Please see Figures 1-4 As shown, this utility model is a cutting device for processing packaging bags, including a support assembly 1. A pneumatic clamp assembly 3 is installed on the top of the support assembly 1 via a rotating assembly 2, and a pneumatic shearing assembly 4 is provided on the bottom side of the support assembly 1. The pneumatic shearing assembly 4 and the rotating assembly 2 are symmetrically arranged.

[0026] The pneumatic clamp assembly 3 includes a pneumatic push rod 301, a hinge plate 302 at the output end of the pneumatic push rod 301, and a movable clamping plate 303 at the other end of the hinge plate 302. The movable clamping plate 303 and the fixed clamping plate 304 are symmetrically arranged.

[0027] By installing the pneumatic clamp assembly 3 on the device, the packaging bag to be cut can be clamped and fixed at different heights when using the device, thus achieving auxiliary clamping to facilitate better cutting work. This makes the device more convenient to use.

[0028] The bracket assembly 1 includes a mounting base plate 101, with support rods 102 mounted on both sides of the top of the mounting base plate 101, and a mounting top rod 103 mounted on the top of the support rods 102. The bracket assembly 1 provides overall structural support, with the mounting base plate 101 providing bottom support and the support rods 102 connecting the mounting base plate 101 and the mounting top rod 103 to form a stable three-dimensional mounting frame, providing a mounting foundation for the rotating assembly 2, the pneumatic clamp assembly 3, and the pneumatic shear assembly 4.

[0029] The rotating assembly 2 includes an extension support plate 201, which is fixedly installed on the outer wall of the mounting rod 103. A pneumatic push rod 202 is mounted on the top of the extension support plate 201 via a bracket. The output end of the pneumatic push rod 202 is provided with a linkage hinge rod 203, and an electric telescopic rod 204 is installed at the end of the linkage hinge rod 203. The pneumatic push rod 202 can brake the electric telescopic rod 204 to achieve rotation. A mounting bracket 205 is installed at the bottom of the electric telescopic rod 204. The rotating assembly 2 uses the pneumatic push rod 202 to push the linkage hinge rod 203, which drives the electric telescopic rod 204 to rotate around the bracket on the extension support plate 201. At the same time, the electric telescopic rod 204 can extend and retract to adjust its length, thereby realizing the position and height adjustment of the bottom mounting bracket 205 and the pneumatic clamp assembly 3.

[0030] A pneumatic push rod 301 is located on the top of the mounting frame 205. A hinge plate 302 is rotatably located on one side of the mounting frame 205. A movable clamping plate 303 and a fixed clamping plate 304 clamp each other. The fixed clamping plate 304 is fixedly installed on the other side of the mounting frame 205. The pneumatic clamping assembly 3 pushes the hinge plate 302 to rotate through the pneumatic push rod 301, causing the movable clamping plate 303 to move closer to or further away from the fixed clamping plate 304 to complete the clamping and release of the packaging bag.

[0031] The pneumatic shearing assembly 4 includes a limiting side plate 401, which is fixedly installed on the top of both sides of the mounting base plate 101. A brake rod 403 is provided between the limiting side plates 401. The middle of the brake rod 403 is connected to the end of the second pneumatic push rod 402 by a hinge. There are two brake rods 403 in total, which are symmetrically arranged. The second pneumatic push rod 402 is installed on the top of the mounting base plate 101 by a bracket. Clamping brackets 404 are fixedly installed on both sides of the brake rod 403. There are two clamping brackets 404 in total, which are symmetrically arranged. A cutting blade 405 is installed at the end of the clamping bracket 404.

[0032] The two cutting blades 405 can be combined together. The pneumatic shearing assembly 4 uses the pneumatic push rod 402 to drive the brake rod 403 to rotate around the limiting side plate 401, which drives the two clamping brackets 404 and the end cutting blade 405 to open and close. When the two cutting blades 405 are combined, the packaging bag is cut.

[0033] This packaging bag processing cutting device achieves overall structural support through the bracket assembly 1. The mounting base plate 101 provides bottom support, and the support rod 102 connects the mounting base plate 101 and the mounting top rod 103, forming a stable three-dimensional mounting frame. This provides the mounting foundation for the rotating assembly 2, the pneumatic clamping assembly 3, and the pneumatic shearing assembly 4. The device relies on the rotating assembly 2 to drive the pneumatic clamping assembly 3 to complete the gripping and position adjustment of the packaging bag. Combined with the pneumatic shearing assembly 4, which is symmetrically arranged with the rotating assembly 2, the device achieves precise clamping, positioning, and cutting of the packaging bag through pneumatic drive and mechanical linkage between the components. Specifically, the rotating assembly 2 uses a pneumatic push rod 202 to push the linkage hinge rod 203, causing the electric telescopic rod 204 to rotate around the bracket on the extension support plate 201. Simultaneously, the electric telescopic rod 204 can extend and retract to adjust its length, thereby achieving position and height adjustment of the bottom mounting frame 205 and the pneumatic clamping assembly 3. The pneumatic clamping assembly 3 uses a pneumatic push rod 301 to push the hinge plate 302. The rotation causes the movable clamping plate 303 to move closer to or further away from the fixed clamping plate 304 to complete the clamping and release of the packaging bag. The pneumatic shearing assembly 4 uses the pneumatic push rod 402 to drive the brake rod 403 to rotate around the limiting side plate 401, thereby driving the clamping brackets 404 on both sides and the end cutting blade 405. The device opens and closes, cutting the packaging bag when the two cutting blades 405 on both sides come together. In the workflow, after the device is powered on, it enters the initial preparation stage, with each pneumatic component in its initial state. At this time, the movable clamping plate 303 and the fixed clamping plate 304 in the pneumatic clamping assembly 3 open, the electric telescopic rod 204 in the rotating assembly 2 retracts, and the two cutting blades 405 on both sides in the pneumatic shearing assembly 4 separate, waiting for the packaging bag to be conveyed to the clamping position. Then, the packaging bag clamping stage begins. The rotating assembly 2 starts first, and the pneumatic push rod 202 pushes the connecting hinge rod 203, causing the electric telescopic rod 204 to rotate directly above the packaging bag. Then, the electric telescopic rod 204 extends, causing the movable clamping plate of the pneumatic clamping assembly 3 to... 303 and the fixed clamping plate 304 are fitted onto the outside of the packaging bag to be clamped. Then the pneumatic clamping assembly 3 is activated. The pneumatic push rod 301 outputs power to push the hinge plate 302 to rotate, which drives the movable clamping plate 303 to move towards the fixed clamping plate 304 until the packaging bag is clamped, thus completing the fixed clamping. The next step is the packaging bag positioning stage. The rotating assembly 2 continues to adjust, and the electric telescopic rod 204 retracts to the preset length. At the same time, the pneumatic push rod 202 pulls the linkage hinge rod 203 in the opposite direction, which drives the electric telescopic rod 204 and the pneumatic clamping assembly 3 that clamps the packaging bag to rotate, transferring the packaging bag to the cutting area of ​​the pneumatic shearing assembly 4, ensuring that the part to be cut is aligned with the cutting blades 405 on both sides.After positioning is completed, the packaging bag cutting stage begins. The pneumatic shearing assembly 4 is activated, and the pneumatic push rod 402 outputs power to drive the two brake levers 403 to rotate inward around the limiting side plate 401. This causes the two clamping brackets 404 to move synchronously towards the center, gradually closing the end cutting blades 405. When the two cutting blades 405 are completely closed, the portion of the packaging bag to be cut is severed, completing the cutting action. Finally, the finished product release and reset stage begins. After cutting, the pneumatic push rod 402 retracts in the opposite direction, driving the brake levers... The rod 403, clamping bracket 404, and cutting blade 405 reset and separate. Simultaneously, the pneumatic push rod 301 in the pneumatic clamping assembly 3 retracts in the opposite direction, pulling the hinge plate 302 to move the movable clamping plate 303 away from the fixed clamping plate 304, releasing the cut packaging bag and causing it to fall into the collection area. Subsequently, the electric telescopic rod 204 in the rotating assembly 2 retracts, and the pneumatic push rod 202 pulls the linkage hinge rod 203, causing the electric telescopic rod 204 and the pneumatic clamping assembly 3 to rotate back to their initial positions, awaiting the processing cycle of the next packaging bag.
