Description

Technical Field

[0001] This utility model relates to the field of waste collection technology for slitting machines, and specifically to a waste collection device for protective film processing. Background Technology

[0002] In the protective film processing industry, slitting machines are commonly used production equipment to cut large rolls of protective film into smaller rolls according to specific specifications. However, the slitting process generates a large amount of waste, such as film debris. If this waste is not cleaned up in time, it will not only scatter around the equipment, polluting the production environment, but may also enter the equipment, affecting its normal operation and even causing malfunctions. Traditional waste cleaning methods often rely on manual labor, requiring operators to periodically stop the machine and manually clean the waste from the equipment. This method is not only inefficient and increases labor costs, but may also pose safety hazards during the cleaning process. Furthermore, manual cleaning is difficult to achieve thoroughly, and some small pieces of waste may still remain on the equipment, affecting subsequent production. To solve these problems, a device is needed that can automatically and efficiently collect the waste generated during the protective film processing. Summary of the Invention

[0023] To provide a clearer explanation and illustration of the technical solution and implementation of this utility model, several preferred specific embodiments for implementing the technical solution of this utility model are introduced below. The following description is merely exemplary and not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these drawings, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically illustrate the concept and principles of the embodiments of this disclosure and do not necessarily show the specific dimensions and scale of each embodiment. Specific parts in particular drawings may be exaggerated to illustrate relevant details or structures of the embodiments of this disclosure. The disclosures of various publications, patents, and published patent specifications cited herein are incorporated herein by reference in their entirety. The technical solution of this utility model will be clearly and completely described below in conjunction with embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model.

[0024] Example 1: Waste collection mechanisms 2 are installed at the top and bottom of the slitting machine 1. In the slitting machine 1, the traction cutting component 12 is the core component. The left side housing 11 is fixed to the left side of the traction cutting component 12 by bolts, and the control box 13 is welded to the right side of the left side housing 11. In the negative pressure generator 21 of the waste collection mechanism 2, the membrane debris collection tank 211 is made of stainless steel, and the air filter element 213 has a cylindrical structure and is fixed to the end cover by screws. The end cover is then locked to the top port of the membrane debris collection tank 211 by bolts. The negative pressure fan 214 is installed on the top of the end cover, and a barrier mesh plate 215 is welded to its bottom port. The suction nozzle 212 is welded to the top of the outer side of the membrane debris collection tank 211. The upper negative pressure pipe 23 and the lower negative pressure pipe 28 are connected to the suction nozzle 212 via tee connectors. The upper collection trough 27 and the lower collection trough 25 are fixed to the top and bottom of the traction cutting component 12 by bolts, and are welded to the side walls of the left-side housing 11 and control box 13. Branch pipes 24 are welded in a linear array to the side walls of the upper negative pressure pipe 23 and the lower negative pressure pipe 28 facing the slitting machine 1, and penetrate through the round holes 26 in the side walls of the upper collection trough 27 and the lower collection trough 25.

[0025] Example 2: Based on Example 1, the waste collection mechanism 2 is optimized. A support plate 22 is welded to the top surface of the control box 13, and the bottom of the membrane debris collection tank 211 is fixed to the upper surface of the support plate 22 with screws to enhance stability. The openings of the upper collection trough 27 and the lower collection trough 25 are designed in a funnel shape to expand the waste suction range. The branch pipe 24 uses a telescopic flexible hose for easy adjustment of the suction angle. The negative pressure fan 214 is driven by a variable frequency motor, and the wind speed can be adjusted according to the amount of waste generated. For the large slitting machine equipment 1, the layout of the waste collection mechanism 2 is adjusted. The length of the traction cutting component 12 of the slitting machine equipment 1 is increased, and the left side casing 11 and control box 13 are correspondingly extended. In the waste collection mechanism 2, the upper negative pressure pipe 23 and the lower negative pressure pipe 28 adopt a segmented design, with each segment connected by a flange for easy installation and maintenance. The upper collection trough 27 and the lower collection trough 25 adopt a segmented splicing structure, with each segment connected by a sealing strip. The membrane debris collection tank 211 has an increased volume and is equipped with multiple air filter elements 213 inside to improve filtration efficiency.

[0026] Example 3: Based on Example 2, an intelligent control system is added. A PLC controller is integrated into the control box 13 of the slitting machine equipment 1, connected to the variable frequency motor of the negative pressure fan 214. Pressure sensors are installed in the upper collection tank 27 and the lower collection tank 25 to monitor waste accumulation in real time. When the pressure exceeds the set value, the PLC controller automatically increases the speed of the negative pressure fan 214 to enhance suction capacity. Simultaneously, a liquid level sensor is installed in the membrane debris collection tank 211. When waste accumulates to a certain height, an alarm device is triggered to remind the operator to clean it. For processing protective membranes of special materials, the filtration system of the waste collection mechanism 2 is adjusted. The slitting machine equipment 1 retains its original structure. In the waste collection mechanism 2, a two-stage filtration system is installed in the membrane debris collection tank 211. The first stage is a coarse filter to intercept large particles of waste; the second stage is a high-efficiency air filter element 213 to filter small particles. The negative pressure fan 214 uses an explosion-proof motor to ensure safety. Static electricity elimination devices are installed at the openings of the upper collection tank 27 and the lower collection tank 25 to prevent static electricity from causing a fire.

[0027] Based on the above preferred technical solution, the workflow of this technical solution is described as follows:

[0028] After the slitting machine 1 starts, the traction cutting component 12 performs traction cutting of the protective film, generating waste such as membrane debris. Simultaneously, the waste collection mechanism 2 starts working, and the negative pressure fan 214 in the negative pressure generator 21 operates, creating a negative pressure environment inside the membrane debris collection tank 211. External air carrying waste is drawn into the membrane debris collection tank 211 through the suction nozzle 212. After the air is filtered by the air filter element 213, the waste is intercepted and retained in the space between the outer surface of the air filter element 213 and the inner wall of the membrane debris collection tank 211. The filtered air is discharged by the negative pressure fan 214. The barrier plate 215 at the bottom port of the negative pressure fan 214 prevents larger debris from accidentally entering and damaging the fan. At the same time, negative pressure is generated by the upper negative pressure... The upper negative pressure pipe 23 and the lower negative pressure pipe 28 transmit the negative pressure. Since the upper negative pressure pipe 23 and the lower negative pressure pipe 28 have several branch pipes 24 fixed in a linear array on the side wall of the slitting machine equipment 1, the negative pressure is applied to the upper collection tank 27 and the lower collection tank 25 through the branch pipes 24. The openings on the side surfaces of the upper collection tank 27 and the lower collection tank 25 that are close to each other form a waste suction channel. The waste generated at the top of the slitting machine equipment 1 is sucked into the upper collection tank 27 by the negative pressure at the opening of the upper collection tank 27, and then drawn into the membrane debris collection tank 211 through the upper negative pressure pipe 23 and the branch pipes 24 connected to the upper collection tank 27.

[0029] Waste generated at the bottom of the slitting machine 1 is drawn into the lower collection tank 25 by negative pressure at the opening of the lower collection tank 25, and then drawn into the membrane debris collection tank 211 through the lower negative pressure pipe 28 and branch pipe 24 connected to the lower collection tank 25. The left and right side walls of the lower collection tank 25 are fixedly connected to the bottom of the left side box 11 and control box 13, which are close to each other. The left and right side walls of the upper collection tank 27 are fixedly connected to the top of the left side box 11 and control box 13, which are close to each other. This fixing method ensures that the collection tanks collect waste stably. When it is necessary to clean the waste in the membrane debris collection tank 211, the operator can open the end cover on the top port of the membrane debris collection tank 211, which is locked by bolts, and take out the air filter element 213 for cleaning or replacement. The bottom surface of the membrane debris collection tank 211 is fixedly connected to the upper surface of the support plate 22 by screws. The support plate 22 is fixed to the top surface of the control box 13, providing stable support for the membrane debris collection tank 211.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
