[0002] Thermal break aluminum includes two aluminum profiles and a heat insulation strip connected between the two aluminum profiles. The production process of aluminum thermal break is generally to first insert the two sides of the heat insulation strip into the notches of the two aluminum profiles, and then roll the vertical heads of the notches to fix the heat insulation strip. This process requires the use of rolling equipment. For example, a thermal break aluminum profile rolling machine disclosed in Chinese invention patent application 2021104524716 is used to realize the rolling of thermal break aluminum.

[0003] In the prior art, the specifications of thermally-insulated aluminum are various, and the heights of the vertical heads required for rolling by the corresponding rolling equipment are also inconsistent. In particular, with the continuous innovation of products, the prior art also has the problem that the heights of the left and right vertical heads in the thermally-insulated aluminum are different, that is, the rolling heights of the left and right sides of the same aluminum profile are different, the rolling heights of the two sides of the upper profile are different, and the rolling heights of the two sides of the lower profile are also different. In the prior art, there is a method of adjusting the height of the upper rolling wheel through a threaded structure to solve the problem of different rolling heights on both sides of the upper profile.

However, this adjustment method has low working efficiency, and the adjustment accuracy is limited by the thickness of the gasket, resulting in low adjustment accuracy. This problem needs to be solved urgently. Utility Model Content

[0030] The following is a detailed description of the embodiments of the present utility model.

[0031] In this embodiment, unless otherwise clearly specified and limited, when terms such as "set on", "connected", and "connected" appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or connected through one or more intermediate media. For those skilled in the art, the specific meanings of the above terms in this embodiment can be understood according to the specific circumstances. The directional words that appear in this embodiment are to better illustrate the characteristics of the features and the relationship between the features. It should be understood that when the placement direction of this embodiment changes, the characteristics of the features and the direction of the relationship between the features also change accordingly. Therefore, the directional words do not constitute an absolute limitation on the characteristics of the features and the relationship between the features in space, but only play a relative limitation role.

[0032] The utility model provides a thermal insulation aluminum rolling equipment, such as Figures 1 to 8 As shown, it includes a frame 1 and a conveying device 5 and multiple sets of rolling devices 2 arranged on the frame 1. The multiple sets of rolling devices 2 are arranged along the conveying direction of the conveying device 5. For example, in the prior art thermal insulation aluminum rolling equipment, three sets of rolling devices 2 are generally arranged. The thermal insulation aluminum conveyed by the conveying device 5 passes through three sets of rolling devices 2 in sequence. The first set is used for guiding, the second set is used for correction, and the third set is used for rolling. Of course, according to different processes, the number of sets of rolling devices 2 can also be different, and other sets of rolling devices 2 should also fall within the protection scope of the present utility model. The three sets of rolling devices 2 are generally driven by a driving mechanism to move simultaneously. The first rotating shaft 31 and the second rotating shaft 41 described below are driven by the driving mechanism to rotate simultaneously, so as to drive the first upper rolling wheel 32 and the first lower rolling wheel 33 installed on the first rotating shaft 31 to rotate simultaneously, and also drive the second upper rolling wheel 42 and the second lower rolling wheel 43 on the second rotating shaft 41 to rotate simultaneously. The structure of the driving mechanism, how the driving mechanism is arranged in the frame 1 and how the driving mechanism is connected to the rolling device 2 are prior art, and reference may be made to prior art such as Chinese invention patent application No. 2021104524716, so its structure will not be repeated in this application.

[0033] The height of the conveying device 5 relative to the frame 1 is fixed. Since the frame 1 is installed on the ground, the height of the conveying device 5 relative to the ground is fixed, and the height of the rolling device 2 relative to the frame 1 is adjustable, that is, the height of the rolling device 2 relative to the ground is adjustable. Further, the height of the rolling device 2 relative to the conveying device 5 is adjustable. This is to adapt to lower profiles of different heights. When the height of the lower profile changes, the height of the vertical head of the lower profile also changes accordingly. The conveying height of the entire production line is fixed. At this time, it is only necessary to adjust the height of the rolling device 2 so that the rolling device 2 adapts to the lower profile. The prior art generally uses a lifting mechanism to realize the lifting and lowering of the rolling device 2. The structure of the lifting mechanism, how the lifting mechanism is set in the frame 1, and how the lifting mechanism is connected to the rolling device 2 are prior art. Reference may be made to prior art such as Chinese invention patent application No. 2021104524716, so its structure is not repeated in this application.

[0034] Each set of rolling devices 2 includes a first side rolling assembly 3 and a second side rolling assembly 4 arranged on both sides of the conveying direction of the thermally-broken aluminum. The first side rolling assembly 3 includes a first rotating shaft 31 and a first upper rolling wheel 32 and a first lower rolling wheel 33 installed on the first rotating shaft 31. The second side rolling assembly 4 includes a second rotating shaft 41 and a second upper rolling wheel 42 and a second lower rolling wheel 43 installed on the second rotating shaft 41. When rolling the thermally-broken aluminum, the first upper rolling wheel 32 and the second upper rolling wheel 42 roll the upper profile of the thermally-broken aluminum, and the first lower rolling wheel 33 and the second lower rolling wheel 43 roll the lower profile of the thermally-broken aluminum.

[0035] It is easy to understand that the first side rolling assembly 3 of each set of rolling devices 2 is located on the same side of the conveying device 5 , and the second side rolling assembly 4 of each set of rolling devices 2 is located on the other side of the conveying device 5 .

[0036] The difference between this embodiment and the prior art mainly lies in the structures of the first side rolling assembly 3 and the second side rolling assembly 4 .

[0037] In this embodiment, the first upper rolling wheel 32 is connected to the first rotating shaft 31 by means of a threaded adjustment structure and can be raised and lowered relative to the first rotating shaft 31, and the first lower rolling wheel 33 is fixed relative to the first rotating shaft 31; the second upper rolling wheel 42 is connected to the second rotating shaft 41 by means of a threaded adjustment structure and can be raised and lowered relative to the second rotating shaft 41, and the second lower rolling wheel 43 is connected to the second rotating shaft 41 by means of a threaded adjustment structure and can be raised and lowered relative to the second rotating shaft 41.

[0038] Through the above-mentioned structural setting, the four rolling wheels in the same rolling device 2 are configured as three movable and one fixed, and the height of the first lower rolling wheel 33 is used as a reference for the lifting mechanism to adjust the overall height of the entire rolling device 2. During production, one of the vertical heads of the thermally broken aluminum is made opposite to the first lower rolling wheel 33, and then the heights of the other three rolling wheels are adjusted so that the heights of the other three rolling wheels are opposite to the other three vertical heads. In this way, the thermally broken aluminum rolling equipment can be quickly adapted to thermally broken aluminum of different models and specifications, and the threaded adjustment structure is used for stepless adjustment, with high adjustment efficiency and high adjustment accuracy.

[0039] In this embodiment, the first side rolling assembly 3 further includes a first bolt 34, a first adjustment cap 35 and a first sleeve 36. The first sleeve 36 is sleeved on the first rotating shaft 31. The first sleeve 36 is circumferentially fixed to the first rotating shaft 31 and can slide along the axial direction of the first rotating shaft 31, that is, when the first rotating shaft 31 rotates, the first sleeve 36 will be driven to rotate at the same time, and the first sleeve 36 can only slide relative to the first rotating shaft 31 but cannot rotate relative to the first rotating shaft 31. The first adjustment cap 35 is threadedly connected to the first sleeve 36. The first bolt 34 passes through the first adjustment cap 35 and is threadedly connected to the middle of the top end of the first rotating shaft 31. After the first bolt 34 is loosened, the first adjustment cap 35 can rotate relative to the first rotating shaft 31. The first upper rolling wheel 32 is connected to the first sleeve 36. In this way, when the height of the first upper rolling wheel 32 needs to be adjusted, the first bolt 34 is first loosened to allow the first adjusting cap 35 to be rotated, and then the first adjusting cap 35 is rotated. With the help of the threaded connection between the first adjusting cap 35 and the first sleeve 36, the first sleeve 36 slides up and down, thereby driving the first upper rolling wheel 32 to slide up and down. When the first upper rolling wheel 32 slides to the desired height, the first bolt 34 is tightened again, the first adjusting cap 35 is locked, and the height adjustment of the first upper rolling wheel 32 is completed.

[0040] In this embodiment, the first sliding sleeve 36 is slidably connected to the first rotating shaft 31 by means of a connection structure of a key slot and a sliding key.

[0041] In this embodiment, the first side rolling assembly 3 further includes a lower flange 37 disposed on the first rotating shaft 31 , and the first lower rolling wheel 33 is fixedly connected to the lower flange 37 .

[0042] Based on the above structure, when the first rotating shaft 31 rotates, it will drive all the above components installed thereon to rotate together, and the height of the first upper rolling wheel 32 relative to the first rotating shaft 31 is adjustable, and the height of the first lower rolling wheel 33 relative to the first rotating shaft 31 is always fixed.

[0043] In this embodiment, the second side rolling assembly 4 further includes a second bolt 44, a second adjustment cap 45 and a second sleeve 46. The second sleeve 46 is sleeved on the second shaft 41. The second sleeve 46 is circumferentially fixed to the second shaft 41 and can slide along the axial direction of the second shaft 41, that is, when the second shaft 41 rotates, the second sleeve 46 is driven to rotate at the same time, and the second sleeve 46 can only slide relative to the second shaft 41 but cannot rotate relative to the second shaft 41. The second adjustment cap 45 is threadedly connected to the second sleeve 46. The second bolt 44 passes through the second adjustment cap 45 and is threadedly connected to the middle of the top end of the second shaft 41. After the second bolt 44 is loosened, the second adjustment cap 45 can rotate relative to the second shaft 41. The second upper rolling wheel 42 is connected to the second sleeve 46. In this way, when the height of the second upper rolling wheel 42 needs to be adjusted, the second bolt 44 is first loosened to allow the second adjusting cap 45 to be rotated, and then the second adjusting cap 45 is rotated. With the help of the threaded connection between the second adjusting cap 45 and the second sleeve 46, the second sleeve 46 slides up and down, thereby driving the second upper rolling wheel 42 to slide up and down. When the second upper rolling wheel 42 slides to the desired height, the second bolt 44 is tightened again, the second adjusting cap 45 is locked, and the height adjustment of the second upper rolling wheel 42 is completed.

[0044] In this embodiment, the second sliding sleeve 46 is slidably connected to the second rotating shaft 41 by means of a connection structure of a key slot and a sliding key.

[0045] In this embodiment, the second side rolling assembly 4 also includes an adjusting sleeve 47 and a third sleeve 48. The third sleeve 48 is sleeved on the second rotating shaft 41. The third sleeve 48 is circumferentially fixed to the second rotating shaft 41 and can slide along the axial direction of the second rotating shaft 41. That is, when the second rotating shaft 41 rotates, the third sleeve 48 will be driven to rotate at the same time, and the third sleeve 48 can only slide relative to the second rotating shaft 41 but cannot rotate relative to the second rotating shaft 41. The adjusting sleeve 47 is connected to the second rotating shaft 41 in an axially fixed and circumferentially rotatable manner. The adjusting sleeve 47 is threadedly connected to the third sleeve 48, and the second lower rolling wheel 43 is connected to the third sleeve 48. In this way, when it is necessary to adjust the height of the second lower rolling wheel 43, the adjusting sleeve 47 is rotated, and the third sleeve 48 slides up and down by means of the threaded connection between the adjusting sleeve 47 and the third sleeve 48, that is, the second lower rolling wheel 43 is driven to slide up and down, thereby completing the height adjustment of the second lower rolling wheel 43.

[0046] In this embodiment, the third sliding sleeve 48 is slidably connected to the second rotating shaft 41 by means of a connection structure of a key slot and a sliding key.

[0047] In order to keep the height of the adjustment sleeve 47 relative to the second rotating shaft 41 unchanged, in this embodiment, the second rotating shaft 41 is provided with a circumferential positioning groove 411, and the adjustment sleeve 47 is provided with a positioning hole 471 connected to the second rotating shaft 41, and a positioning block 472 is provided in the positioning hole 471, and the positioning block 472 partially extends into the positioning groove 411. In this way, the positioning block 472 is inserted into the positioning groove 411 to limit the up and down movement of the adjustment sleeve 47, and the positioning block 472 only extends into the positioning groove 411 but does not press against the positioning groove 411, so that the adjustment sleeve 47 can rotate relative to the second rotating shaft 41.

[0048] In this embodiment, the adjusting sleeve 47 is provided with a locking hole 473 connected to the third sliding sleeve 48, and the locking hole 473 is threadedly connected with a top screw 474, and a copper washer 475 is placed between the top screw 474 and the third sliding sleeve 48. The top screw 474 is used to lock and unlock the adjusting sleeve 47 and the third sliding sleeve 48. When the height of the second lower rolling wheel 43 needs to be adjusted, the top screw 474 is first loosened to allow the adjusting sleeve 47 to rotate relative to the third sliding sleeve 48. After the second lower rolling wheel 43 is adjusted to the required height, the top screw 474 is re-tightened, and the adjusting sleeve 47 and the third sliding sleeve 48 are relatively fixed. In order to prevent the top screw 474 from damaging the thread of the third sliding sleeve 48, a copper washer 475 is placed between the top screw 474 and the third sliding sleeve 48 in this embodiment. The copper washer 475 is more easily deformed and will not damage the thread of the third sliding sleeve 48 when tightened.

[0049] In summary, this type of rolling equipment can quickly adapt to thermally broken aluminum of different models and specifications, with high adjustment efficiency and high adjustment accuracy.

[0050] In the absence of conflict, the above-mentioned embodiments and features thereof may be combined with each other.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the preferred technical solutions of the utility model, rather than limiting the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solutions of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the utility model.
