Description

Technical Field

[0001] This utility model belongs to the field of reflective aluminum coil production technology, specifically relating to a cutting device for reflective aluminum coil production. Background Technology

[0002] Reflective aluminum can be used in a wide range of applications, including signs, nameplates, vehicle license plates, vehicle body reflectivity, and architectural decoration. It mainly involves coating the aluminum base with reflective adhesive and protective adhesive layers, and requires multiple processes such as unwinding, applying adhesive layers, bonding metal reflective layers, drying, applying reflective adhesive layers, drying, applying protective adhesive layers, drying, and rewinding.

[0003] In the actual production and processing process, in order to meet production needs, large aluminum coils usually need to be cut and slit to meet different processing requirements. Existing aluminum coil cutting devices typically include an unwinding device, a conveyor roller group, a cutting blade and a cutting blade drive assembly, and a slitting and rewinding device arranged in sequence. The cutting blade drive assembly and the cutting blade are located above the aluminum sheet to be cut. The cutting blade drive assembly drives the cutting blade to press down, cutting the aluminum coil into the required length and then slitting and rewinding it. Since the aluminum coil is separated into two sections by the cutting blade after cutting, the ends of the aluminum sheet at the cut section need to be manually pulled through under the cutting blade and pulled to the slitting and rewinding device for the next cutting and slitting and rewinding. Continuous cutting and rewinding is not possible, which is very inconvenient. Each cut requires manual operation, which is not only cumbersome but also unsafe and inefficient.

[0004] Therefore, in order to solve the above problems, it is necessary to develop a cutting device for the production of reflective aluminum coils. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cutting device for the production of reflective aluminum coils, which realizes continuous cutting and automatic winding, is easy and labor-saving to operate, and effectively improves work efficiency and operational safety.

[0006] The purpose of this utility model is achieved as follows: A cutting device for producing reflective aluminum coils includes a frame, an unwinding assembly on the frame, a horizontal transmission roller group on one side of the unwinding assembly, a steering roller on the other side of the horizontal transmission roller group, an upper transmission roller group below the steering roller, a cutting assembly below the upper transmission roller group, a lower transmission roller group below the cutting assembly, a winding assembly below the lower transmission roller group, and multiple sets of positioning components around the winding assembly.

[0007] The cutting assembly includes a cutting support plate fixedly mounted on the frame, a cutting blade on one side of the cutting support plate, and a horizontal drive assembly fixedly connected to the other side of the cutting blade. The cutting support plate and the cutting blade together form a cutting space through which the aluminum sheet can pass.

[0008] The positioning component includes a rotating plate disposed on one side of the winding component. One end of the rotating plate is rotatably connected to a hinge seat, and the other end is close to the winding component. A rotating component is disposed on the side of the rotating plate close to the winding component, and a telescopic spring and an adsorption component are disposed on the other side of the rotating plate close to the winding component. The adsorption component drives the rotating plate to rotate through adsorption force. During the rotation adjustment process, the rotating plate drives the rotating component to abut or separate from the surface of the aluminum sheet wound on the winding component through the elastic action of the telescopic spring.

[0009] Furthermore, a tensioning roller is also provided between the unwinding assembly and the horizontal transfer roller group.

[0010] Furthermore, the cutting support plate has a square opening adapted to the cutting blade, through which the cutting blade can pass.

[0011] Furthermore, the width of the cutting blade is set to be adapted to or greater than the width of the aluminum coil.

[0012] Furthermore, the horizontal drive assembly is a pneumatic cylinder assembly or a hydraulic cylinder assembly.

[0013] Furthermore, the positioning components are disposed on the left and right sides and the bottom side of the winding component in the direction of rotation, and the positioning components are configured in three or four groups.

[0014] Furthermore, the rotating component is a rotating wheel or a rotating roller.

[0015] Furthermore, the adsorption component is implemented using an electromagnet component.

[0016] Furthermore, the rack is also equipped with a controller and a drive power supply.

[0017] Furthermore, a meter counter is also installed on the frame.

[0018] The beneficial effects of this utility model are as follows: By adopting a steering structure, the winding assembly is positioned below the cutting assembly. After cutting, the aluminum sheet automatically hangs down due to its own gravity, and combined with the power conveying of the upper transmission roller group, it automatically passes through the cutting space and enters the lower transmission roller group, realizing continuous feeding at the cutting assembly. This eliminates the need for manual pulling of the aluminum sheet, resulting in higher safety and easier, less labor-intensive operation. Furthermore, by setting multiple positioning components around the winding assembly, the aluminum sheet conveyed to the winding assembly by the upper and lower transmission roller groups is pressed firmly, allowing it to adhere to the winding rollers of the winding assembly, achieving automatic winding of the cut aluminum sheet and automatic rewinding of the slit sheet. In summary, this utility model has the advantages of continuous cutting and automatic rewinding, safe, convenient, and labor-saving operation, and high cutting efficiency.

[0026] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a cutting device for producing reflective aluminum coils includes a frame 1, on which an unwinding assembly 2 is mounted. A horizontal transmission roller group 3 is mounted on one side of the unwinding assembly 2, and a guide roller 4 is mounted on the other side of the horizontal transmission roller group 3. An upper transmission roller group 5 is mounted below the guide roller 4, a cutting assembly 6 is mounted below the upper transmission roller group 5, a lower transmission roller group 7 is mounted below the cutting assembly 6, and a winding assembly 8 is mounted below the lower transmission roller group 7. Multiple sets of positioning components 9 are arranged around the winding assembly 8. Preferably, a tension roller 10 is also mounted between the unwinding assembly 2 and the horizontal transmission roller group 3. The aluminum sheet unwound by the unwinding assembly 2 is sequentially wound around the tension roller 10, the horizontal transmission roller group 3, the guide roller 4, and the upper transmission roller group 5, and then passes through the cutting assembly 6 into the lower transmission roller group 7 before being wound onto the winding assembly 8.

[0028] The cutting assembly 6 includes a cutting support plate 6a fixedly mounted on the frame 1. A cutting blade 6b is provided on one side of the cutting support plate 6a. Preferably, the cutting support plate 6a has a square opening 6e adapted to the cutting blade 6b and allowing the cutting blade 6b to pass through, facilitating complete cutting of the aluminum sheet by the cutting blade 6b. A horizontal drive assembly 6c is fixedly connected to the other side of the cutting blade 6b. The cutting support plate 6a and the cutting blade 6b together form a cutting space 6d through which the aluminum sheet can pass. The horizontal drive assembly 6c drives the cutting blade 6b to move in the direction of the aluminum sheet passing through the cutting space 6d until the cutting blade 6b completes the cutting of the aluminum sheet. After the cutting is completed, the cutting blade 6b is driven to return to its original position. Preferably, the width of the cutting blade 6b is adapted to or greater than the width of the aluminum coil, facilitating complete cutting of the aluminum sheet by the cutting blade 6b. Preferably, the horizontal drive assembly 6c can be a cylinder assembly or a hydraulic cylinder assembly.

[0029] The positioning component 9 includes a rotating plate 9a disposed on one side of the winding component 8. One end of the rotating plate 9a is rotatably connected to a hinge seat 9b, and the other end is close to the winding component 8. A rotating element 9c is disposed on the side of the rotating plate 9a near the winding component 8. Preferably, the rotating element 9c can be a rotating wheel or a rotating roller. The rotating wheel or rotating roller can abut against the surface of the aluminum sheet wound on the winding component and maintain relative rotation, so that the aluminum sheet can be wound on the winding roller of the winding component. A telescopic spring 9d and an adsorption component 9e are disposed on the other side of the rotating plate 9a near the winding component 8. The adsorption component 9e drives the rotating plate 9a to rotate through adsorption force. Preferably, the adsorption component 9e can be implemented by an electromagnet component. During the rotation adjustment process, the rotating plate 9a drives the rotating element 9c to abut or separate from the surface of the aluminum sheet wound on the winding component 8 through the elastic action of the telescopic spring 9d.

[0030] Preferably, the positioning components 9 are disposed on the left and right sides and the bottom side of the winding component 8 in the direction of rotation, and the positioning components 9 are configured in three or four groups.

[0031] The specific implementation process of the positioning component 9 automatically winding the aluminum sheet onto the winding component is as follows: The leading end of the aluminum sheet is driven by the lower transmission roller group 7 and transported to the top of the winding component 8. Based on the winding rotation direction of the winding component 8, the adsorption components 9e of the positioning component 9, arranged along the winding direction, are activated sequentially. The adsorption component 9e adsorbs and drives the rotating plate 9a to rotate away from the winding component 8. During rotation, the rotating plate 9a drives the rotating part 9c to change from a contact state to a separation state with the winding component 8. At this time, the telescopic spring 9d is further compressed until the leading end of the aluminum sheet passes through the position of the rotating part 9c, at which point the adsorption component 9e stops. After the adsorption stops and the rotating plate 9a loses the adsorption force of the adsorption component, it is pushed by the reset elastic force of the telescopic spring 9d and rotates towards the winding component 8 until the rotating part 9c abuts against the outer surface of the aluminum plate. At the same time, the aluminum plate is tightly pressed against the winding roller of the winding component 8, so that it can be wound along the winding roller. During the winding process with the rotation of the winding roller of the winding component 8, its head end passes through the positioning component 9 set along the winding direction in sequence. Whenever it passes the positioning component 9, the adsorption component 9e of the positioning component 9 is activated to perform the above operation process, tightly pressing the aluminum plate against the winding roller of the winding component 8, realizing the automatic winding of the aluminum plate.

[0032] Preferably, the frame 1 is also equipped with a meter counter for automatically measuring the length of the cut aluminum sheet, which facilitates automatic cutting and makes it more convenient and labor-saving to use.

[0033] The frame 1 is also equipped with a controller and a drive power supply. The controller and drive power supply are electrically connected to the unwinding assembly 2, tension roller 10, horizontal transmission roller group 3, steering roller 4, upper transmission roller group 5, cutting assembly 6, lower transmission roller group 7, winding assembly 8, positioning assembly 9, and meter counter. It should be noted that the unwinding assembly 2 and winding assembly 8 should respectively include an unwinding roller and a winding roller assembly for receiving aluminum sheets, as well as a drive assembly such as a drive motor for driving the unwinding roller and the winding roller to rotate respectively, and other necessary components. This is common knowledge to those skilled in the art, so no specific limitations are made here. The controller, drive power supply, unwinding assembly 2, tension roller 10, horizontal transmission roller group 3, steering roller 4, upper transmission roller group 5, cutting assembly 6, lower transmission roller group 7, winding assembly 8, positioning assembly 9, and meter counter, as well as their specific circuit connection structures, are all prior art and common knowledge to those skilled in the art. No other special requirements are made in this application, as long as they can achieve the functions described in this application, so no specific limitations are made here.

[0034] In a specific implementation of this utility model, during a single cutting process, the unwinding assembly 2 unwinds the aluminum sheet. The first end of the aluminum sheet passes sequentially through the tension roller 10, the horizontal transmission roller group 3, the steering roller 4, and the upper transmission roller group 5, and then passes through the cutting assembly 6 into the lower transmission roller group 7. With the assistance of the positioning assembly 9, it automatically winds onto the winding assembly 8. When the aluminum sheet wound on the winding assembly 8 reaches the required length, unwinding and winding stop, and the cutting assembly 6 is started to cut the aluminum sheet. The cut aluminum sheet separates at the cutting space 6d, with the upper end being the first end of the next cut and the lower end being the last cut. The lower transmission roller group 7 and the winding assembly 8 are then started to continue rotating to complete the slitting of this segment. The aluminum sheet can be coiled up. When cutting for the next time, the uncoiling assembly 2, tension roller 10, horizontal transmission roller group 3, steering roller 4, and upper transmission roller group 5 are started again. At this time, the first end of the aluminum sheet to be cut is located in the upper part of the cutting space 6d. Under the driving transmission of the upper transmission roller group 5 and its automatic gravity, it moves down automatically until it is transmitted to the lower transmission roller group 7. Under the driving action of the lower transmission roller group 7 and its own gravity, it continues to move down. With the assistance of the positioning assembly 9, it is automatically wound onto the coiling assembly 8. The above process is repeated to complete the automatic continuous cutting. There is no need to manually pull the cut aluminum sheet. The operation is convenient and labor-saving, safer, and more efficient.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
