Description

Technical Field

[0001] The utility model relates to the technical field of plastic bag production, in particular to a cutting device for plastic bag processing. Background Art

[0002] Plastic bags are bags made of plastic as the main raw material. They are indispensable items in people's daily lives and are often used to hold other items. They are widely used because of their advantages of being cheap, extremely light, large in capacity and easy to store. However, due to the disadvantages of plastic bags' extremely long degradation cycle and difficulty in disposal, their production and use are banned in some countries.

[0003] The existing patent announcement number CN215471672U, entitled "A Bag Cutting Device for Plastic Bag Production and Processing", proposes that the utility model is provided with a cutting blade. When the plastic bag needs to be cut during processing, the plastic bag is pushed into the bottom end of the cutting blade, and then the drive motor inside the equipment box starts to operate, so that the cutting blade cuts the plastic bag through the heating plate on the cutting table. When the cut plastic bag enters the bag cutting device body through the feed port, the servo motor starts to operate, and the operation of the servo motor causes the threaded rod to rotate. The rotation of the threaded rod causes the sleeve rod to extend, so that the push plate pushes the cut plastic bag to be discharged through the discharge port, which is very convenient.

[0004] When the appealed patent cuts the next section of plastic bag, it is necessary to manually pull the plastic bag out of the lower end of the cutting blade to a specified length, and then start the drive motor to allow the cutting blade to cut the plastic bag. This process has the following shortcomings: first, the plastic bag needs to be pulled out manually, and the processing efficiency is low. Second, there is a certain risk because the human hand shuttles around the lower end of the cutting blade. Third, the employee cannot pull the plastic bag out to the specified length. Therefore, it is necessary to propose a cutting device for plastic bag processing to solve the above problems. Utility Model Content

[0013] Technical effects and advantages of this utility model:

[0014] 1. When using the device, the plastic bag to be cut is placed on the processing table, the cutting component is operated to cut the plastic bag. When the next section of the plastic bag needs to be cut, the convenient component is moved to the top of the end of the next section of the plastic bag through the power component, the end of the next section of the plastic bag is adsorbed by the convenient component, and then the convenient component is reversely displaced by the power component, so that the next section of the plastic bag is pulled out from under the cutting component by a specified distance. This process does not require manual pulling out of the plastic bag, does not require manual movement under the cutting component, and can pull out the specified length of the plastic bag, thereby solving the problems of the existing plastic bag processing cutting device when cutting the next section of the plastic bag, first, the need to manually pull out the plastic bag, which has low processing efficiency, second, there is a certain risk due to manual movement under the cutting component, and third, the employee cannot pull the plastic bag to the specified length;

[0015] 2. When the lifting plate and the cutting knife move downward, the pressure plate touches the plastic bag first, so that when the lifting plate and the cutting knife continue to move downward, the spring is compressed and elastic, thereby pressing and flattening the two ends of the cut part of the plastic bag, avoiding the problem of uneven cutting caused by the deviation of the plastic bag when cutting the plastic bag. After the lifting plate and the cutting knife move upward, the pressure plate can also press the plastic bag, preventing the plastic bag from moving upward with the cutting knife, causing the suction cup to be unable to adsorb the end of the plastic bag.

[0024] Furthermore, the convenient component includes a movable plate 12, which is slidably arranged between the two side plates 1 through a power component. Electric push rods 13 are fixedly arranged at both ends of the bottom of the movable plate 12, and a connecting plate 14 is fixedly connected between the telescopic ends of the two electric push rods 13. A plurality of evenly distributed suction cups 15 are fixedly arranged at the bottom of the connecting plate 14, and a diversion pipe is arranged inside the connecting plate 14. The diversion pipe and the suction cup 15 are connected to each other. An electric vacuum pump 16 is fixedly arranged on the top of the movable plate 12, and the electric vacuum pump 16 is connected to the diversion pipe through a corrugated hose 17.

[0025] Specifically, when the convenient component is above the end of the next section of plastic bag, the electric push rod 13 is started, so that the connecting plate 14 and the suction cup 15 are synchronously displaced downward, so that the suction cup 15 is close to the end of the plastic bag, and the electric air pump 16 is started to pump air into the suction cup 15, so that the plastic bag can be firmly adhered to the suction cup 15, and then the electric push rod 13 is started in the reverse direction to drive the end of the plastic bag to rise a small distance to avoid the problem of the plastic bag falling off the suction cup 15 due to contact between the processing table 2 when being pulled out. The power component is used to drive the convenient component to move a specified distance, thereby pulling the plastic bag out of a specified length, and finally the electric push rod 13 is started to put the plastic bag down, and the electric air pump 16 is started at the same time to perform air buffering inside the suction cup 15, so that the plastic bag and the suction cup 15 are separated from each other, wherein the electric air pump 16 is designed to be used for both pumping and inflating.

[0026] Furthermore, the power assembly includes a first slide groove 8, which is fixedly arranged on one of the side plates 1, and a motor 9 is fixedly arranged at the end of the first slide groove 8.

In order to improve the stability of the displacement of the movable plate 12, a second slide groove with the same length as the first slide groove 8 is provided on the other side plate 1. The end of the movable plate 12 away from the movable block 11 is movable and extends into the second slide groove, and is adapted to the second slide groove. The displacement stability of the movable plate 12 is improved through the limit support of the second slide groove.

[0028] Furthermore, the cutting assembly includes a support frame 3, which is fixedly arranged on the top of the two side panels 1. A hydraulic cylinder 4 is fixedly arranged on the inner wall of the top of the support frame 3. The telescopic end of the hydraulic cylinder 4 is fixedly connected to a lifting plate 5. A detachable cutting knife 6 is arranged at the bottom of the lifting plate 5, and a cutting groove 7 corresponding to the position of the cutting knife 6 is provided on the upper surface of the processing table 2.

[0029] Start the hydraulic cylinder 4 to drive the lifting plate 5 and the cutting knife 6 to move downward, and cut the plastic bag through the cooperation of the cutting groove 7.
