Description

Technical Field

[0001] The utility model relates to the field of die-cutting processing equipment, in particular to a base film waste discharge and recycling device. Background Art

[0002] In the current die-cutting industry, after a die-cutting operation, the base film is often not effectively recycled because of the difficult-to-remove glue stains on the surface. This situation has led to a large waste of base film resources, which not only increases production costs, but also imposes a certain degree of burden on the environment. As the concept of sustainable development has become popular, how to achieve efficient recycling of base film has become one of the problems that the die-cutting industry needs to solve. Utility Model Content

[0003] In view of this, the utility model provides a base film waste discharge and reuse device, which can efficiently scrape off the glue stains adhered to the base film through a scraper rod to restore the cleanliness of the base film, thereby realizing the reuse of the base film, significantly reducing the waste of the base film, realizing the recycling of resources, thereby reducing production costs and improving production efficiency.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A base film waste discharge and recycling device comprises a machine base, a material discharge roller arranged on the machine base, a material collection roller arranged on the machine base, a first material roller located next to the material discharge roller, a second material roller located next to the material collection roller, and a scraper rod located between the first material roller and the second material roller.

[0006] The scraper rod is located between the first material roller and the second material roller and is the core component of the device. The scraper rod can efficiently scrape off the glue stains adhering to the base film and restore the cleanliness of the base film, thereby realizing the reuse of the base film, significantly reducing the waste of the base film, realizing the recycling of resources, thereby reducing production costs and improving production efficiency.

[0007] Preferably, one end of the scraper rod is connected to the output end of the first lifting cylinder, and the other end is connected to the output end of the second lifting cylinder.

[0008] The scraper bar achieves efficient removal of glue stains on the base film. Its two ends are connected to the output ends of the first lifting cylinder and the second lifting cylinder respectively. This structural layout not only gives the scraper bar precise positioning capabilities, but also ensures its stability and reliability during operation. When the scraper bar needs to be moved to a specific position, the synergy of the first lifting cylinder and the second lifting cylinder enables the scraper bar to rise or fall smoothly, thereby accurately adjusting the distance between the scraper bar and the base film. This precise control capability means that the scraper bar can effectively scrape off glue stains without damaging the base film, maintaining the integrity and service life of the base film. In addition, this design also improves the working efficiency of the scraper bar. Through the rapid response of the cylinder, the scraper bar can complete multiple scraping actions in a short period of time, greatly speeding up the cleaning speed of the base film. This efficient working mode is crucial for continuous operation on the production line because it can significantly reduce downtime and improve overall production efficiency.

[0009] Preferably, a scraper is provided at the bottom of the scraper rod.

[0010] The working principle of the scraper bar is to use the scraper at the bottom to peel off and remove the glue stains adhering to the bottom film when it contacts the bottom film. This process is not only fast, but also effective, and can quickly restore the cleanliness of the bottom film to the standard that it can be reused. The efficient operation of the scraper bar directly translates into improved production efficiency. By reducing the waste of bottom film, enterprises can not only save raw material costs, but also reduce environmental pollution caused by improper disposal of waste bottom film. This recycling of resources is not only in line with the concept of sustainable development, but also brings considerable economic benefits to enterprises. At the same time, the application of the scraper bar also improves production efficiency. Because the bottom film can be quickly cleaned and put back into use, the material flow speed on the production line can be accelerated, reducing downtime and improving the operating efficiency of the production line. This efficient operation method helps enterprises better meet market demand and enhance their competitiveness.

[0011] Preferably, a knife groove is dug at the bottom of the scraper rod, and the scraper is embedded in the knife groove.

[0012] The bottom of the scraper rod is dug with a knife groove, which allows the scraper to be firmly embedded in it, ensuring that when scraping the glue stains on the base film, the scraper and the base film maintain a constant contact pressure and angle, thereby achieving uniform and efficient scraping. This design not only improves the scraping accuracy, but also reduces the sliding and jumping of the scraper during the working process, extending the service life of the scraper.

[0013] Preferably, a first inclined surface and a second inclined surface are dug on both sides of the bottom of the scraper rod.

[0014] The first and second bevels on both sides of the bottom of the scraper bar further optimize the scraping performance. The existence of these two bevels enables the scraper bar to adapt to the bending and undulations of the base film when it contacts the base film, achieving a scraping that fits the base film more closely, reducing the risk of incomplete scraping or scratching the base film. At the same time, the bevel design also helps guide the scraper during the scraping process, ensuring that the scraper always moves along the correct path, improving the consistency and repeatability of scraping.

[0015] Preferably, the scraper rod is provided with a fixing hole connected to the blade groove, and a threaded member for fixing the scraper is installed in the fixing hole.

[0016] The scraper rod is provided with a fixing hole connected to the knife groove and a threaded piece for fixing the scraper. This design provides great convenience for the installation and adjustment of the scraper. The scraper can be easily fixed on the scraper rod through the threaded piece, and the position and angle of the scraper can be adjusted as needed to adapt to the base film of different thickness and texture. This adjustable design enables the scraper rod to flexibly cope with various working conditions, improving the adaptability and flexibility of the work.

[0017] Preferably, the blade of the scraper is in an inverted V shape.

[0018] The blade of the scraper is designed in an inverted V shape. This unique shape brings significant advantages to the scraping process. The inverted V-shaped blade can cut into the glue stains on the base film more effectively, and can provide sufficient cutting force to ensure thorough scraping, whether it is scraping thick or thin glue. In addition, the inverted V-shaped blade can naturally guide the movement direction of the scraper during the scraping process, reducing the lateral sliding of the scraper on the base film, thereby reducing the risk of scratching the base film and protecting the integrity of the base film.

[0019] Preferably, the blade of the scraper is arranged outwards.

[0020] The blade of the scraper is set outwards. This design allows the scraper to be closer to the edge of the base film during the scraping process, reducing the gap between the scraper and the edge of the base film and improving the scraping accuracy. At the same time, the design of the blade facing outwards also makes the cutting resistance of the scraper relatively small during the scraping process, which helps to reduce the wear of the scraper and extend the service life of the scraper. In addition, this design also facilitates the installation and removal of the scraper, improving the convenience of work.

[0021] Preferably, the lifting direction of the scraper rod is perpendicular to the line connecting the first material roller and the second material roller.

[0022] The design that the lifting direction of the scraper rod is perpendicular to the line connecting the first material roller and the second material roller enables the scraper rod to maintain the best contact angle with the material roller during the lifting process. This vertical design ensures that the scraper rod can apply pressure evenly when scraping the bottom film. No matter what height the scraper rod is at, it can ensure that the contact surface between the scraper and the bottom film remains consistent, thereby achieving stability and reliability in the scraping process. The advantages of this design are that it improves the scraping efficiency, ensures the scraping quality, reduces the wear of the scraper during the scraping process, and extends the service life of the scraper.

[0023] Preferably, the unloading roller and the collecting roller are symmetrically placed on both sides of the scraper rod.

[0024] The unwinding roller and the receiving roller are placed symmetrically on both sides of the scraper rod. This symmetrical layout is not only beautiful, but also has significant functional advantages. The symmetrically placed unwinding roller and the receiving roller can ensure the balance of the bottom film during the conveying process, avoiding the deflection or winding of the bottom film caused by uneven force on one side. This balanced conveying method helps to improve production efficiency and reduce downtime caused by bottom film problems. In addition, the symmetrical layout also simplifies the maintenance of the equipment, because the two unwinding rollers and the receiving roller are the same in structure and working principle, which is convenient for unified management and maintenance.

[0025] Compared with the prior art, the utility model has the following beneficial effects:

[0026] The scraper rod of the utility model is located between the first material roller and the second material roller, and is the core component of the device. The scraper rod can efficiently scrape off the glue stains adhered to the base film to restore the cleanliness of the base film, thereby realizing the reuse of the base film, significantly reducing the waste of the base film, realizing the recycling of resources, thereby reducing production costs and improving production efficiency.
