Description

Technical Field

[0001] The utility model relates to the technical field of aluminum plate laminating, in particular to a double-sided aluminum plate laminating machine. Background Art

[0002] In order to avoid surface scratches on the aluminum plate during transportation or installation, a double-sided laminating machine will be used to cover both sides of the aluminum plate with a film after the aluminum plate is manufactured, thereby protecting the filter plate during transportation and installation.

[0003] In the process of using a double-sided laminating machine to laminate aluminum plates, when using a pressure roller to press the film onto the surface of the aluminum plate, due to the difference in thickness of different types of aluminum plates, the height of the pressure roller needs to be adjusted. After the adjustment is completed, the pressure roller is fixed so that the distance between the pressure roller and the aluminum plate is constant. However, the thickness of the aluminum plate of the same model varies due to factors such as the rolling speed, tension setting or cooling shrinkage of the aluminum plate. This makes the distance between the pressure roller and the aluminum plate constant, resulting in uneven pressure on the film when it is pressed onto the aluminum plate, which in turn causes the film to be damaged due to excessive pressure or the film to be weakened due to insufficient pressure, which makes it easy for bubbles to appear or the film to be loosely adhered to the surface of the aluminum plate.

[0004] Therefore, a double-sided aluminum plate laminating machine is urgently needed to solve the above problems. Utility Model Content

[0025] Adjusting assembly includes adjusting hole 201 set up in mounting frame 101, adjusting hole 201 is connected with adjusting block 203 through guide rail 202, one end of rotating shaft 105 is connected with adjusting block 203 through bearing 204, the top end of mounting frame 101 is connected with mounting plate 205 through bolt, mounting plate 205 is slidingly connected with adjusting rod 206, one end of adjusting rod 206 is connected with adjusting block 203, the other end of adjusting rod 206 is fixedly connected with adjusting tube 207, adjusting tube 207 is connected with multiple counterweight rings 208 through connecting assembly,

[0026] It should be noted here that: through the setting of the adjustment component, the constant weight of the counterweight ring 208 and the dynamic connection of the upper pressure roller 106 in the adjustment hole 201 are utilized, so that the upper pressure roller 106 applies a constant pressure to the film 103, thereby reducing the uneven pressure on the film 103 caused by the thickness error of the aluminum plate body 102, thereby reducing the risk of damage or bubbles and loose adhesion of the film 103 during covering, thereby improving the quality of double-sided film 103 covering the aluminum plate body 102.

[0027] It is worth noting that: as an existing technology, the specific structure and working principle of the double-sided laminating machine have been mastered by people in this field, and will not be elaborated on here. This application only briefly illustrates the covering of the film 103 by the upper pressure roller 106 and the lower pressure roller 107 (the local position of the double-sided laminating machine), and the specific structure will not be elaborated on here.

[0028] See also Figure 5 and Figure 6 The connecting assembly shown in the figure includes a connecting tube 301 fixedly connected to the bottom wall of the adjusting tube 207, the connecting tube 301 is connected to a connecting rod 302 through a limit assembly, each counterweight ring 208 is connected to the connecting rod 302 through a guide assembly, a retaining ring 303 is fixedly connected to the side wall of the connecting rod 302, a threaded strip 304 is formed on the side wall of the connecting rod 302, and the threaded strip 304 is threadedly connected to a threaded ring 305;

[0029] It should be noted here that: through the setting of the connecting component, the counterweight ring 208 can be installed in the adjusting tube 207, and the position of the counterweight ring 208 in the adjusting tube 207 can be limited.

[0030] See also Figure 6 The guide assembly shown in the figure includes two symmetrical guide grooves 401 provided on the side wall of the connecting rod 302. The two guide grooves 401 are slidably connected to the guide bars 402. One side of the two guide bars 402 is connected to the inner wall of the counterweight ring 208.

[0031] It should be noted here that the guide assembly is provided to limit the position of the counterweight ring 208 on the connecting rod 302 .

[0032] Working principle: When double-sided lamination is performed on the aluminum plate body 102, the aluminum plate body 102 to be laminar is placed on the conveying roller 104, and the aluminum plate body 102 is conveyed by the conveying roller 104. During the conveying process, when the aluminum plate body 102 is conveyed between the upper pressing roller 106 and the lower pressing roller 107, the film 103 is pressed and covered on the upper surface and the lower surface of the aluminum plate body 102 by the upper pressing roller 106 and the lower pressing roller 107 respectively. Figure 2 , thereby achieving double-sided lamination operation on the aluminum plate body 102;

[0033] Before laminating the aluminum plate body 102 with the film 103, the pressure applied by the upper pressing roller 106 to the film 103 can be adjusted according to the model of the aluminum plate body 102. During the adjustment process, a corresponding number of counterweight rings 208 are sleeved onto the side walls of the connecting rod 302 under the action of the guide assembly, and the counterweight rings 208 sleeved onto the side walls of the connecting rod 302 are locked using the threaded ring 305. Then, the connecting rod 302 is inserted into the connecting tube 301 and the position is limited by the limit assembly.

[0034] After a corresponding number of counterweight rings 208 are installed in the adjustment tube 207, the weight of each counterweight ring 208 will be applied to the upper pressure roller 106, thereby causing the upper pressure roller 106 to provide pressure when covering the film 103, and the weight of the counterweight ring 208 is constant and the upper pressure roller 106 is dynamically connected to the adjustment hole 201, so that the upper pressure roller 106 applies constant pressure to the film 103, thereby reducing the uneven pressure on the film 103 caused by the thickness error of the aluminum plate body 102, thereby reducing the risk of damage or bubbles and loose adhesion of the film 103 when covering, thereby improving the quality of double-sided film 103 covering the aluminum plate body 102.

[0035] Example 2

[0036] See also Figure 5 and Figure 6 , this embodiment further explains Example 1. The limiting assembly shown in the figure includes two symmetrically arranged fixing holes 501 opened on the side wall of the connecting rod 302 near the connecting tube 301. The two fixing holes 501 are slidably connected to the limiting blocks 502. The inner wall of the connecting tube 301 is provided with two limiting holes 503. The two limiting holes 503 are matched with the limiting blocks 502. The two limiting blocks 502 are provided with inclined surfaces 504 on the side close to the connecting tube 301. The adjusting tube 207 is provided with a driving assembly for driving the two limiting blocks 502. The bottom walls of the two fixing holes 501 are fixedly connected to springs 505. The other ends of the two springs 505 are connected to the limiting blocks 502.

[0037] It should be noted here that: by setting the limiting assembly, the connection rod 302 is limited, and the stability of each counterweight ring 208 during use is further guaranteed.

[0038] See also Figure 5 , the driving assembly shown in the figure includes two T-shaped driving rods 601 slidably connected to the side wall of the regulating tube 207, and the opposite ends of the two T-shaped driving rods 601 are located inside the limiting hole 503 and are fixedly connected to the driving plate 602;

[0039] It should be noted here that the arrangement of the driving assembly facilitates the contact limiting between the connecting rod 302 and the connecting tube 301 .

[0040] Working principle: When installing each counterweight ring 208 in the adjustment tube 207, first use the connecting assembly to install the required number of counterweight rings 208 on the side wall of the connecting rod 302, then insert one end of the connecting rod 302 into the connecting tube 301. During the process of inserting the connecting rod 302 into the connecting tube 301, when the two limit blocks 502 abut against the side wall of the connecting tube 301, the interaction force of the inclined surface 504 and the guiding effect of the fixing hole 501 will push the two limit blocks 502 to move forward. The limiting block 502 contracts into the fixing hole 501. As the connecting rod 302 is continuously inserted, when the two limiting blocks 502 are aligned with the limiting hole 503, the elastic action of the spring 505 pushes the two limiting blocks 502 into the limiting hole 503 and abuts against the bottom wall of the limiting block 503. Thus, the connecting rod 302 is limited by the abutting action of the two limiting holes 502, further ensuring the stability of each counterweight ring 208 during use.

[0041] When it is necessary to increase or decrease the number of counterweight rings 208 installed on the connecting rod 302, the T-shaped driving rod 601 is pressed to push the driving plate 602 to move in the limiting hole 503, and the movement of the driving plate 602 is used to push the limiting block 502 out of the limiting hole 503, thereby releasing the limit between the connecting rod 302 and the connecting tube 301, and then facilitating the removal of the connecting rod 302 from the adjusting tube 207, thereby facilitating the increase or decrease in the number of counterweight rings 208 on the connecting rod 302 to meet the coating requirements of different models of aluminum plate bodies 102.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
