Description

Technical Field

[0001] This invention relates to the field of paper feeding machine technology, specifically to a paper feeding machine for rapidly cutting packaging paper. Background Technology

[0002] A packaging paper feeder is a specialized piece of equipment used in the packaging industry. It primarily controls the conveying and positioning of packaging materials (such as paper and plastic film) during the packaging production process. Compared to paper feeders used in the general paper industry, packaging paper feeders typically require more precise control to accommodate different types and sizes of packaging materials.

[0003] Existing packaging paper feeding machines are divided into those with and without cutting structures. Packaging paper feeding machines without cutting structures require tearing the packaging paper by hand after packaging an item. Packaging paper feeding machines with cutting structures require control by foot or press switch after packaging an item. Foot-operated switches are prone to hand-foot incoordination, affecting cutting efficiency, and the foot needs to be constantly on the switch. Pressing switches requires one hand to press the switch, which is also relatively inefficient. Therefore, a paper feeding machine that can quickly cut packaging paper is designed. Summary of the Invention

[0004] The purpose of this invention is to provide a paper feeder for rapidly cutting packaging paper, so as to solve the problem of low paper cutting efficiency of packaging paper feeders mentioned in the background art.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Please see Figure 1-4 A paper feeder for rapidly cutting packaging paper includes a paper feeder body 1, a cutting module 2 disposed on one side of the paper feeder body 1, and the cutting module 2 and the paper feeder body 1 being fixed together in a detachable manner. Preferably, the paper feeder body 1 has two sockets 4 fixed on the side near the housing 21, and the side wall of the housing 21 is provided with a plug 3, and the plug 3 and the socket 4 are plugged in and matched.

[0016] The cutting module 2 and the paper feeder body 1 are electrically connected by a wire 5. Specifically, the wire 5 extends out of the electrical box 22 and has a charging head 6 at its end. A socket 7 is provided on the side wall of the paper feeder body 1. The cutting module 2 and the paper feeder body 1 are electrically connected by inserting the charging head 6 into the socket 7.

[0017] The paper feeder body 1 feeds out the honeycomb paper for packaging, and the cutting module 2 cuts it. Traditional paper feeders do not have a cutting structure. They are usually torn by hand or a cutting mechanism is set up. However, the cutting mechanism is controlled by a foot switch, but sometimes the hands and feet are not synchronized, resulting in low paper cutting efficiency.

[0018] In this invention, the cutting module 2 includes a housing 21, which has a semi-enclosed structure and a pad 23 fixedly connected to the middle. A slide rod 24 and a lead screw 25 are provided on the top of the pad 23. The slide rod 24 is fixed to the housing 21. The lead screw 25 is driven by a servo motor fixed to the side wall of the housing 21. An electrical box 22 is fitted outside the servo motor. The lead screw 25 passes through a paper cutting head 26 and is threadedly connected to it. The paper cutting head 26 slides along the slide rod 24. A proximity switch 27 is provided on the top of the housing 21. A trigger head 28 is provided below the proximity switch 27. The trigger head 28 passes through the housing 21 and its bottom abuts against the paper passing below. When the paper passes through and abuts against the trigger head 28, the top of the trigger head 28 touches the proximity switch 27.

[0019] The electrical box 22 contains a PLC, a servo driver, a servo motor, and a power module. The power module is connected to the wire 5. The proximity switch 27 is connected to the PLC, the PLC is connected to the servo driver, and the servo driver is connected to the servo motor. When the proximity switch 27 receives a touch signal, it transmits the signal to the PLC. The PLC controls the servo driver to send pulses, which in turn causes the servo motor to run.

[0020] The servo motor runs and drives the lead screw 25 to rotate. The lead screw 25 drives the paper cutting head 26 to move along the slide bar 24. After cutting the paper at its bottom, it returns to its original position.

[0021] The trigger head 28 has the following structure: It includes a guide rod 281 that penetrates the top wall of the housing 21. A limit ring 282 is located in the middle of the guide rod 281, and a spring 284 is fitted onto it. The spring 284 is located between the limit ring 282 and the bottom of the housing 21. The guide rod 281 has threads, and an adjusting nut 285 is threaded onto its top. The adjusting nut 285 is located above the housing 21. A roller 283 is rotatably connected to the bottom of the guide rod 281. When the paper is wrapped and needs to be cut, simply twist the paper. As the paper twists, it will press against the roller 283 and push the entire guide rod 281 upwards. The top of the guide rod 281 contacts the proximity switch 27. The proximity switch 27 receives the corresponding signal and transmits it to the PLC.

[0022] The guide rod 281 has a groove on its side wall, and a sleeve 8 is fitted on the outside of the guide rod 281. The inner wall of the sleeve 8 has a protrusion, and the protrusion is slidably installed in the groove. The sleeve 8 is fixedly inserted into the through hole of the guide rod 281 at the top of the housing 21. The sleeve 8 allows the guide rod 281 to slide smoothly up and down without the threads scratching the housing 21.

[0023] Preferably, the paper cutting head 26 has the following structure: the paper cutting head 26 includes a blade holder, the blade holder and the lead screw 25 are threadedly connected and slidably connected to the slide rod 24, the bottom of the blade holder is rotatably connected to the blade, and the blade and the top of the pad 23 abut against each other.

[0024] Working Principle: This invention provides a rapid paper feeding machine for cutting packaging paper. In use, the plug 3 is inserted into the socket 4, connecting and fixing the paper feeding machine body 1 and the cutting module 2. The paper feeding machine body 1 feeds out the honeycomb paper for packaging, which is then cut by the cutting module 2. Traditional paper feeding machines do not have a cutting structure and are generally operated by hand tearing, or by setting up a cutting mechanism. However, the cutting mechanism is controlled by foot pedals or a press switch, resulting in low paper cutting efficiency. The cutting method in this invention is as follows: The trigger head 28 passes through the housing 21 and its bottom abuts against the paper passing below. When the paper is wrapped, it needs to be cut. Simply twist the paper. As the paper twists, it will abut against the roller 283 and push the entire guide rod 281 upward. The top of the guide rod 281 contacts the proximity switch 27. The proximity switch 27 receives the corresponding signal and transmits the signal to the PLC. The PLC controls the servo driver to send pulses, which in turn causes the servo motor to run. The servo motor runs and drives the lead screw 25 to rotate. The lead screw 25 drives the paper cutting head 26 to move along the slide bar 24. After the bottom of the head cuts the paper, it resets.

[0025] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
