Description

Technical Field

[0001] This application relates to the field of aluminum strip cutting technology, specifically to an aluminum strip trimmer. Background Technology

[0002] Edge trimmers are frequently used in aluminum strip finishing equipment. The waste edges after trimming need to be collected by winding or crushing. When the thickness of the aluminum strip is ≤3mm, the waste edges are generally collected by winding. When the thickness of the aluminum strip is >3mm, the edge crushing mode is activated.

[0003] In existing technologies, conventional edge trimming and shredding mechanisms consist of two independent edge trimmers and edge shredders. During operation, the strip material is sheared by the disc of the edge trimmer, and the resulting waste edge enters the edge shredder through a guide groove. The edge shredder's edge shredder then shreds the strip material into suitable lengths. The shredded waste material enters the waste bin, thus completing the entire edge trimming and shredding process. However, when the strip material thickness exceeds 10 mm, the diameter of the edge shredder becomes relatively large, and the distance between the edge trimmer and the edge shredder becomes relatively far. This results in a large bending angle for the waste edge when it passes through the waste edge guide groove, making it difficult to thread the strip. Furthermore, the waste edge tends to accumulate in the guide groove, requiring frequent machine shutdowns for manual clearing. This leads to a decrease in equipment operating rate and, in severe cases, triggers tool overload damage, affecting production efficiency. Summary of the Invention

[0004] This application provides an aluminum strip trimmer that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: an aluminum strip edge trimmer, comprising a base; two drive shafts are mounted on the upper left side of the outer side of the base, the two drive shafts rotating synchronously at the same speed, and circular edge trimmers are mounted on the drive shafts, the two circular edge trimmers being symmetrically arranged vertically and interlocking together, the circular edge trimmers being positioned at the edge of the aluminum strip; two drive shafts are mounted on the right side of the outer side of the base, the two drive shafts being mounted on each drive shaft, the edge trimmers being positioned close to the circular edge trimmers.

[0006] The edge-breaking cutter includes a mounting plate, which is fixedly mounted on the output shaft of the second drive shaft. The outer side of the mounting plate is provided with multiple mounting grooves, and a shearing blade protruding from the mounting plate is provided in the mounting groove. The end of the shearing blade is provided with an arc-shaped surface. The shearing blades mounted on the upper and lower mounting plates are engaged together at the meshing point. A guide plate is mounted on the base.

[0007] Preferably, both the second drive shaft and the first drive shaft are connected to the output shaft of an external motor via a coupling.

[0008] Preferably, each of the mounting discs has six mounting slots evenly distributed in a ring on its outer surface.

[0009] Preferably, the shearing blade is fixed in the mounting groove by bolts.

[0010] Preferably, the guide plate consists of a horizontal section and an inclined section. The horizontal section is set close to the outer side of the circular cutting blade, and the inclined section points downward toward the mounting plate. The guide plate is set below the biting point of the two circular cutting blades.

[0011] Preferably, an inclined guide channel is installed on the outer side of the base, the inlet of the guide channel is located close to the mounting plate, and a waste collection box is provided at the outlet of the guide channel.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] 1. This application integrates the circular cutting blade and the edge-breaking blade into the same base and adopts a symmetrical interlocking cutting and edge-breaking blade design, which significantly improves the efficiency of cutting and edge-breaking. The mounting plate of the edge-breaking blade has multiple sets of shearing blades on the outside, and with the arc blade design, it can effectively reduce the blade diameter requirement while ensuring the shearing strength. At the same time, the cutting and edge-breaking blades are close together, avoiding the problem of sharp bends in the guide groove caused by the excessively large edge-breaking shearing volume when the strip thickness is >10mm.

[0014] 2. The guide plate adopts a combination structure of horizontal and inclined sections. The horizontal section closely follows the outer side of the circular cutting blade to guide the waste edge for precise feeding, avoiding the 90° sharp bend of the traditional guide channel. This greatly reduces the abnormal friction between the waste edge and the guide surface and the risk of rebound jamming, solves the problem of large-thickness waste edge accumulation, and reduces the frequency of downtime for troubleshooting.

[0015] 3. The shearing blade is fixed to the mounting plate by bolts and has a detachable structure, which supports quick replacement or adjustment of the blade configuration. By replacing the shearing blade with different curvatures and adjusting the tilt angle of the guide plate, the equipment's compatibility with multi-specification production is significantly enhanced.

Figure 1 The orientations or positional relationships shown are for the convenience of describing this application and simplifying the description only, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0021] Please see Figure 1-2 This application provides the following technical solution: an aluminum strip edge trimmer, including a base 7; two synchronously rotating drive shafts 1 are installed on the upper left side of the outer side of the base 7, and circular edge trimmers 2 are installed on the drive shafts 1. The two circular edge trimmers 2 are symmetrically arranged vertically and interlocked together. The circular edge trimmers 2 are located at the edge of the aluminum strip 4; two drive shafts 9 are installed on the right side of the outer side of the base 7. There are two drive shafts 9, and each drive shaft 9 is equipped with an edge trimmer 3. The edge trimmers 3 are arranged close to the circular edge trimmers 2.

[0022] Specifically, the aluminum strip 4 moves from left to right, and the edges of the aluminum strip 4 are first cut off by two synchronously rotating and interlocking circular cutting blades 2 to form waste strip. Then the waste strip enters the edge-breaking blade 3, and the two synchronously rotating edge-breaking blades 3 cut the waste strip into segments.

[0023] The edge-breaking cutter 3 includes a mounting plate 34, which is fixedly mounted on the output shaft of the second drive shaft 9. The outer side of the mounting plate 34 is provided with multiple mounting grooves 33. A shearing blade 32 protruding from the mounting plate 34 is provided in the mounting groove 33. The end of the shearing blade 32 is provided with an arc-shaped surface. The shearing blades 32 mounted on the upper and lower mounting plates 34 are engaged together at the meshing point 31. A guide plate 8 is mounted on the base 7.

[0024] Specifically, the guide plate 8 feeds the waste strip into the edge-breaking cutter 3. Since the guide plate 8 is in close contact with the cutting point of the circular edge-breaking cutter 2, the edge generated by cutting directly contacts the guide plate 8, which can effectively prevent the edge from bending at a large angle.

[0025] More specifically, the mounting plate 34 is a circular plate, and the shearing blade 32 is a strip blade.

[0026] Furthermore, both the second drive shaft 9 and the first drive shaft 1 are connected to the output shaft of an external motor via a coupling.

[0027] Furthermore, each of the mounting discs 34 has six mounting slots 33 evenly distributed in a ring on its outer surface.

[0028] Furthermore, the shearing blade 32 is fixed in the mounting groove 33 by bolts.

[0029] Specifically, the bolt connection facilitates the replacement of the shear blade 32.

[0030] Furthermore, the guide plate 8 is composed of a horizontal section and an inclined section. The horizontal section is set close to the outer side of the circular cutting blade 2, and the inclined section points downward toward the mounting plate 34. The guide plate 8 is set below the biting point of the two circular cutting blades 2.

[0031] Furthermore, an inclined guide channel 5 is installed on the outer side of the base 7, the inlet of the guide channel 5 is located close to the mounting plate 34, and a waste collection box 6 is provided at the outlet of the guide channel 5.

[0032] Specifically, waste collection bin 6 is used to collect waste materials after cutting.

[0033] In use: The aluminum strip 4 moves from left to right. Two synchronously rotating and interlocking circular cutting blades 2 first cut off the edge of the aluminum strip 4 to form a waste strip. It first contacts the guide plate 8. Under the guidance of the guide plate 8, the waste strip passes between the two mounting plates 34. When the shearing blades 32 set on the outer surface of the two synchronously rotating mounting plates 34 interlock, the waste strip is cut off. The cut waste strip is sent into the waste collection box 6 through the guide groove 5.

[0034] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
