DETAILED DESCRIPTION

[0075] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0076] Example 1

[0077] like Figures 1 to 10 As shown, this embodiment provides a metal roof, characterized by comprising:

[0078] There are two color steel plates, both of which have a pressed edge 1;

[0079] The pressing plate 2 has pressing sections 3 at both ends and an abutting section 4 in the middle. The abutting section 4 is used to abut against the pressing edge 1. The pressing ends and the pressing edge 1 form a pressing groove 5.

[0080] A locking machine, characterized in that it is used for processing a metal roof, comprising:

[0081] A first frame 6, a second frame 7 and a pressing assembly 8, the pressing assembly 8 is used to press or separate the first frame 6 and the second frame 7;

[0082] A first pressing wheel group 9, which includes a plurality of first pressing wheel groups 9 and is disposed on the first frame 6;

[0083] The second pressing wheel group 10 includes a plurality of second pressing wheel groups 10, and the second pressing wheel group 10 is arranged on the second frame 7;

[0084] A driving member 11 is provided on the first frame 6 and is used to drive the first pressing wheel assembly 9 to rotate;

[0085] After the first frame 6 and the second frame 7 are pressed tightly, the first pressing wheel group 9 drives the second pressing wheel group 10 to rotate, and the first pressing wheel group 9 and the second pressing wheel group 10 cooperate to press the pressing section 3;

[0086] A first conical wheel set 12 is rotatably mounted on the first frame 6 and is located between two adjacent first pressing wheel sets 9;

[0087] The second conical wheel group 13 is rotatably arranged on the second frame 7 and is located between the two adjacent second pressing wheel groups 10. The first conical wheel group 12 and the second conical wheel group 13 form a conical pressing gap, and the pressing section 3 and the pressing edge 1 pass through the conical pressing gap. After the first conical wheel group 12 and the second conical wheel group 13 rotate, they are used to press the pressing section 3 and the pressing edge 1 to form an inclined edge.

[0088] In this embodiment, in order to perform the edge locking operation on the metal roof, the edge locking machine in this scheme is divided into two frames, wherein the first frame 6 has a plurality of first pressing wheel groups 9, a first conical wheel group 12 and a driving member 11, and the second frame 7 has a plurality of second pressing wheel groups 10 and a second conical wheel group 13. Specifically, when the two frames are clamped together, the wheel assemblies cooperate with each other to press the metal roof, wherein the specific pressing process of the pressing plate 2 of the metal roof and the pressing edge 1 is as follows Figures 8 to 10 As shown, first, after the initial pressing by the first pressing wheel group 9 and the second pressing wheel group 10, the pressing section 3 is bent inward and pressed against the pressing edge 1, and then processed by two cone wheels, the pressing section 3 and the pressing edge 1 are bent at a certain angle to facilitate the subsequent secondary pressing. When the pressing section 3 and the pressing edge 1 have a certain bevel angle, they are pressed by the two wheel assemblies to complete the second inward bending, thereby achieving the effect of twice locking the edge. Compared with the single-sided locking machine in the prior art, this solution performs a secondary pressing on the special pressing plate 2 of the metal roof, and uses the one-time forming and pressing of the locking machine, which greatly improves the work efficiency while also having a great improvement in wind resistance compared with the prior art.

[0089] Furthermore, the pressing assembly 8 includes: a pressing rod 14, which has a plurality of pressing rods 14, one end of which is provided on the first frame 6, and the other end of which is a threaded section 15, and the threaded section 15 passes through the second frame 7;

[0090] There are a plurality of adjusting nut plates 16 , one of which is provided on each threaded segment 15 . The adjusting nut plates 16 are rotatably mounted on the second frame 7 via a bearing. The adjusting nut plates 16 rotate to drive the second frame 7 toward or away from the first frame 6 .

[0091] There are several rotating handles 17, which are respectively arranged on several adjusting nut plates 16;

[0092] Linking rod 18 , several rotating handles 17 are connected through the linking rod 18 .

[0093] In this embodiment, the clamping assembly 8 of this scheme is designed in the form of threaded locking. Compared with the elastic clamping mechanism in the prior art, the clamping effect of this scheme is stronger and the adjustable stroke is richer. It can be adjusted for color steel plates and pressed plates 2 of different thicknesses. The specific structure is that a number of clamping rods 14 are set on the first frame 6, and the end of the clamping rod 14 is a threaded section 15, and it is made to pass through the second frame 7. By rotating the adjusting nut plate 16 on the threaded section 15, the clamping degree of the two frames is adjusted. In particular, the adjusting nut plate 16 of this scheme has a handle 17 for easy rotation. It should be noted that the rotation in this scheme is at the same horizontal position, and the rotating shaft is connected through a linkage to ensure that all nut plates rotate the same number of turns when one nut plate is rotated, thereby ensuring that the two frames are in the same clamping state horizontally.

[0094] Furthermore, it also includes:

[0095] There are two fixing components 19, which are respectively provided on the first frame 6 and the second frame 7 and located in the pressing groove 5;

[0096] The fixing assembly 19 includes:

[0097] Mounting seat 20, the mounting seat 20 is arranged on the first frame 6 or the second frame 7;

[0098] A first fixing member 21, one end of which is hingedly mounted on the mounting base 20, and the other end of which has a first guide wheel 22;

[0099] A second fixing member 23, one end of the second fixing member 23 is hingedly disposed on the mounting seat 20, and the other end has a second guide wheel 24, the first guide wheel 22 abuts against the pressing section 3, and the second guide wheel 24 abuts against the pressing edge 1;

[0100] The first elastic member 25 has one end disposed on the first fixing member 21 and the other end disposed on the second fixing member 23 . The first elastic member 25 is used to provide a force to move the first fixing member 21 and the second fixing member 23 away from each other.

[0101] In this embodiment, since the pressing plate 2 may slide during the pressing process, resulting in inconsistent lengths of the two pressing sections 3, this solution is designed with a fixing assembly 19 in its two pressing grooves 5. Specifically, a mounting frame is provided on both frames, and its position corresponds to the pressing groove 5. Two fixing parts are hingedly provided on the mounting frame, and the top of the fixing part has a pulley. At the same time, a spring is provided between the two fixing parts. The two fixing parts are moved away from each other by the elastic force of the spring. When the pressing operation is performed, since there is this fixing assembly 19 in both pressing grooves 5, one of the two fixing parts is in contact with the pressing section 3 and the other is in contact with the pressing edge 1, the size of the two pressing grooves 5 is ensured to be consistent, which solves the problem that the sliding of the pressing plate 2 causes inconsistent lengths of the pressing section 3, resulting in the inability to lock the edges.

[0102] Furthermore, it also includes:

[0103] A first support frame 26, the first support frame 26 is hingedly disposed on the first frame body 6;

[0104] A first pressing roller 27 is rotatably mounted on the first support frame 26 and has a plug-in slot 28;

[0109] The third elastic member 33 has one end disposed on the second frame 7 and the other end disposed on the second pressing roller 30 . The third elastic member 33 is used to provide a force for the second pressing roller 30 to abut against the abutting section 4 .

[0110] In this embodiment, in order to avoid the situation where the pressing plate 2 is misaligned up and down due to extrusion during the pressing process, this solution is designed with a downward pressure device on the two frames to apply a downward pressure to the pressing plate 2 to limit its longitudinal displacement. Specifically, the frame is provided with a support frame, and a pressing roller is hingedly installed on the support frame, and a spring is provided to provide a downward pulling force for the pressing roller. What is special is that in this solution, the first pressing roller 27 has a plug-in groove 28, and the second pressing roller 30 has a plug-in protrusion 31. When the two frames are pressed against each other, the two pressing rollers are plugged into each other to form a complete pressing roller, thereby ensuring that the pressing plate 2 will not be misaligned longitudinally during the pressing process.

[0111] Furthermore, the first pressing wheel group 9 and the second pressing wheel group 10 each include:

[0112] The first rotating shaft 34 is rotatably mounted on the first frame 6 or the second frame 7.

[0113] A first driven wheel 35 , which is disposed on the first rotating shaft 34 , and the driving member 11 drives the first driven wheel 35 to rotate;

[0114] The pressing wheel 36 is disposed on the first rotating shaft 34 and rotates along with the first rotating shaft 34;

[0115] Also includes:

[0116] A second rotating shaft 37, the second rotating shaft 37 is rotatably disposed on the first frame 6;

[0117] The first connecting wheel 38, which has several first connecting wheels 38, is arranged on the second rotating shaft 37. After the first frame 6 and the second frame 7 are abutted, the first connecting wheel 38 rotates and cooperates with the first driven wheel 35 of the first pressing wheel group 9 and the first driven wheel 35 of the second pressing wheel group 10 respectively.

[0118] In this embodiment, in order to further improve the working efficiency of the device, a transmission structure is provided between the first pressing wheel group 9 and the second pressing wheel group 10 of this scheme, so that during the pressing process, the second pressing wheel group 10 is no longer a simple follow-up role, and the second pressing wheel group 10 has a certain driving force, thereby ensuring the consistency of pressing on both sides during the pressing process. At the same time, since both sides have driving force, the working efficiency of this scheme is further improved.

[0119] Furthermore, the pressing wheel 36 has pressing protrusions 40 at both ends, and a pressing gap is formed between the pressing protrusions 40 at both ends. The pressing gap is connected to the conical pressing gap, and the pressing section 3 and the pressing edge 1 pass through the pressing gap and the conical pressing gap in sequence.

[0120] Furthermore, the first frame 6 has a first sliding groove 41, the second frame 7 has a second sliding groove 42, and further includes:

[0121] The first pre-pressing component 43 is disposed in the first frame 6.

[0122] The second pre-pressing assembly 44 is disposed in the second frame 7. The first pre-pressing assembly 43 and the second pre-pressing assembly 44 have the same structure, and both include:

[0123] A third rotating shaft 45, the third rotating shaft 45 is rotatably disposed on the first frame 6 or the second frame 7;

[0124] The second driven wheel 61 is arranged on the third rotating shaft 45, and the first driven wheel 35 drives the second driven wheel 61 to rotate;

[0125] Cam 48, cam 48 is arranged on the third rotating shaft 45, and both sides of cam 48 have convex edges 49;

[0126] The extrusion member 50 is slidably arranged on the first sliding groove 41.

[0127] There are a plurality of first pulleys 51 , all of which are rotatably mounted on the extrusion member 50 ;

[0128] The second pulley 52 includes a plurality of second pulleys 52, all of which are rotatably mounted on the extrusion member 50. The first pulley 51 and the second pulley 52 form a limiting gap, and the convex edge 49 is located in the limiting gap. After the cam 48 rotates, the first pulley 51 and the second pulley 52 roll along the convex edge 49, and the extrusion member 50 slides along the first slide groove 41 or the second slide groove 42;

[0129] After the first pre-pressing assembly 43 and the second pre-pressing assembly 44 are matched, the extrusion piece 50 is used to pre-extrude the pressing section 3 .

[0130] In this embodiment, since the pressing section 3 of the pressing plate 2 is arranged at a right angle to the pressing edge 1 of the color steel plate, it may be that the pressing is not completely completed when passing through the first pressing wheel group 9 during the pressing process. In order to solve this problem, this solution is designed with a pre-pressing component, which pre-stamps the pressing section 3 slightly to make it bend at a certain angle to facilitate the subsequent bending of the first pressing wheel group 9. Specifically, a third rotating shaft 45 is provided on both frames, which has a second driven wheel 61 and a cam 48. The second driven wheel 61 rotates with the first driven wheel 35 and drives the cam on the third rotating shaft. The wheel 48 rotates, wherein the cam 48 is a structure with a convex edge 49, and the extrusion piece 50 cooperating with the cam 48 is clamped on the convex edge 49 by the first pulley 51 and the second pulley 52. ​​When the cam 48 rotates to its small diameter, the extrusion piece 50 extends, and when the cam 48 rotates to the large diameter, the extrusion piece 50 is retracted. As the cam 48 rotates, the extrusion piece 50 reciprocates in this way, so that when the locking operation is performed, the pressing section 3 can be pre-extruded and bent at a certain angle to facilitate subsequent operations. This solution greatly improves the working efficiency of pressing and locking by setting pre-extrusion.

[0131] Furthermore, the second frame 7 has a plurality of sockets 53 and further includes:

[0132] The latches 54 , which are in plurality, are disposed on the first frame 6 . After the first frame 6 and the second frame 7 are pressed together, the latches 54 are inserted into the insertion holes 53 .

[0133] Furthermore, it also includes:

[0134] There are multiple telescopic rods 56, which are arranged on the first frame 6 and the second frame 7;

[0135] Steering seats 57, which have a plurality of steering seats 57 and are rotatably arranged on the telescopic rod 56 on the second frame 7;

[0136] There are a plurality of rotating wheels 59, which are rotatably mounted on the telescopic rod 56 of the first frame 6;

[0137] There are several steering wheels 60 , and the steering wheels 60 are arranged on the steering seat 57 .

[0138] In this embodiment, in order to ensure smooth operation during the pressing process of the first frame 6 and the second frame 7, a steering seat 57 is installed on the telescopic rod 56 on the second frame 7. When it is necessary to adjust the pressing state of the second frame 7 and the first frame 6, the steering seat 57 is rotated, and the steering wheel 60 on the steering seat 57 is directed toward the first frame 6. After the adjustment is completed, the steering seat 57 is rotated again so that the steering wheel 60 and the rotating wheel 59 are in the same direction, ensuring the forward and backward movement of the entire overlock machine.

[0139] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
