DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figure 1-Figure 7 , which is the first embodiment of the utility model, provides a roller adjustment device for rolling metal materials. The roller adjustment device for rolling metal materials includes a main body component 100, an adjustment component 200 and an opening and closing component 300. The three can cooperate to quickly replace the rollers according to the material.

[0033] Specifically, the main component 100 includes a rolling roller 101, a first placement rack 102, a second placement rack 103 and a base 104. The first placement rack 102 is arranged at one end of the rolling roller 101, the second placement rack 103 is arranged at the other end of the rolling roller 101, and the base 104 is arranged at the bottom of the first placement rack 102 and the second placement rack 103, and both are arranged in the second placement rack 103.

[0034] A locking groove is provided on the inner wall of the roller 101. By moving the expansion plate to the inner wall of the locking groove of the roller 101 for support, the two are tightly fitted. At this time, the adjacent locking grooves of the roller 101 are convex, and the convex part can provide stronger supporting force, thereby preventing the roller 101 from being deformed. The engagement of the expansion plate with the locking groove can prevent the roller 101 from separating from the expansion plate.

[0035] The rolling roller 101 is mainly used for rolling processing of metal materials. The rolling roller 101 is usually large in size and heavy in weight. The primary function of the first placement rack 102 and the second placement rack 103 is to physically support the rolling roller 101, and the base 104 is used to stably support the first placement rack 102 and the second placement rack 103.

[0036] Since the materials rolled by the roller 101 are different, the roller 101 can be replaced and adjusted accordingly according to the material quality and the size of the required rolling.

[0037] Specifically, the adjustment assembly 200 includes an adjustment part 201, including a sliding ring 201a, a moving ring 201b, a threaded rod 201c, a fixed block 201d and a connecting rod 201e. The moving ring 201b is rotatably connected to the sliding ring 201a, the threaded rod 201c is arranged on the inner wall of the moving ring 201b, the moving ring 201b is movably connected to the threaded rod 201c, the sliding ring 201a is threadedly connected to the threaded rod 201c, there are four fixed blocks 201d, all of which are arranged on the surface of the moving ring 201b, and there are four connecting rods 201e, all of which are hinged to the fixed block 201d.

[0038] The adjustment assembly 200 is disposed between the first placement rack 102 and the second placement rack 103 , and the roller 101 is used to roll the metal material.

[0039] The rolling roller 101 is prepared with multiple fixed sizes. The support roller below the rolling roller 101 is of fixed size and does not need to be replaced or adjusted in position. A driving motor fixed to one side of the first placement rack 102 is provided at the end of the supporting roller. The driving motor is used to drive the supporting roller to rotate, so that the supporting roller drives the metal material on its top to move. When facing materials of different materials, it is only necessary to replace the rolling roller 101 with the corresponding material to perform fine processing on the material. When it is necessary to adjust the distance between the rolling roller 101 and the support roller, the distance between the two can be changed by moving the rolling roller 101, thereby processing materials with different requirements.

[0040] When the material needs to be rolled, when the roller 101 needs to be replaced with a material of a different material, the sliding ring 201a is rotated, and the sliding ring 201a moves on the threaded rod 201c. The movement of the sliding ring 201a drives the moving ring 201b to move, and the movement of the moving ring 201b drives the fixed block 201d to move, and the movement of the fixed block 201d drives the connecting rod 201e to move.

[0041] Specifically, the opening and closing assembly 300 is arranged on one side of the threaded rod 201c, and includes an opening and closing member 301, including a door body 301a, a moving bar 301b and a locking block 301c. The moving bar 301b is arranged on one side of the door body 301a, and the locking block 301c is arranged on one side of the moving bar 301b for locking.

[0042] A door shaft is inserted into the inner wall of the door body 301a, and the door shaft is fixed in the second placement rack 103. The door body 301a is movably connected to the door shaft.

[0043] When the roller 101 needs to be replaced, the locking block 301c is lifted to separate the locking block 301c from the moving bar 301b, and then the door body 301a is pulled, and the door body 301a moves and drives the moving bar 301b to move. After the door body 301a is opened, the roller 101 can be placed. After the placement is completed, the door body 301a is pushed, and the door body 301a moves and drives the moving bar 301b to move, so that the moving bar 301b squeezes the chamfer of one end of the locking block 301c, so that the locking block 301c is opened and then engaged with the moving bar 301b, thereby completing the closing of the door body 301a.

[0044] Example 2

[0045] Reference Figure 1-Figure 7 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0046] Specifically, a connecting plate 202a is hinged between the two connecting rods 201e, and an expansion plate 202b is provided on the top of each connecting plate 202a.

[0047] The inner wall shape of the expansion plate 202b fits the inner wall of the roller 101, and a plurality of slots are provided on the expansion plate 202b to increase friction.

[0048] When the connecting rod 201e moves, it drives the four connecting plates 202a to move, and the movement of the connecting plate 202a drives the four expansion plates 202b to move.

[0049] Specifically, a connecting shaft 202c is provided at one end of the threaded rod 201c, four hinged rods 202d are hinged on the connecting plate 202a, and the other end of the hinged rod 202d is hinged to a fixed plate 202e.

[0050] The connecting shaft 202c is used to support the fixed plate 202e, and the fixed plate 202e is used to support the hinge rod 202d. By moving the connecting plate 202a, the hinge rod 202d is driven to move, and the movement of the hinge rod 202d can increase the supporting force of the expansion plate 202b.

[0051] Specifically, a fixing ring 202f is provided on the inner wall of the fixing plate 202e, and the fixing ring 202f is sleeved on the outer side of the connecting shaft 202c.

[0052] The fixing ring 202f is used to support the fixing plate 202e, and the connecting shaft 202c is used to support the fixing ring 202f.

[0053] Specifically, four support rods 202g are hinged on the outer side of the connecting plate 202a, and the other end of the support rod 202g is hinged to a placement block 202h.

[0054] The placement block 202h is used to support the support rod 202g. When the connecting plate 202a moves, it will also drive the support rod 202g to move. Through the movement of the support rod 202g, a supporting force can be provided to one end of the expansion plate 202b.

[0055] Specifically, a placement ring 202i is provided at one end of the placement block 202h, and the placement ring 202i is sleeved on one end of the connecting shaft 202c.

[0056] The placement ring 202i is used to support the placement block 202h.

[0057] Specifically, a support shaft 302a is fixed to one end of the movable bar 301b, and the other end of the support shaft 302a is fixed to one side of the door body 301a. A rotating shaft 302b is inserted into the inner wall of the locking block 301c, and the rotating shaft 302b is movably connected to the locking block 301c. A support frame 302c is sleeved on the outside of the rotating shaft 302b, a chamfer 301c-1 is provided at the end of the locking block 301c, and a right-angle surface 301c-2 is provided on the inner wall of the locking block 301c.

[0058] The support shaft 302a is used to support the moving bar 301b, the rotating shaft 302b is used to support the locking block 301c, and the support frame 302c is used to support the rotating shaft 302b. The moving bar 301b squeezes the chamfer 301c-1 at one end of the locking block 301c to open the locking block 301c. The setting of the right-angled surface 301c-2 on the locking block 301c makes it impossible to squeeze the locking block 301c open when the moving bar 301b is in the locking block 301c, thereby preventing the moving bar 301b from moving out of the locking block 301c by itself.

[0059] Specifically, a torsion spring 302d is sleeved on the outer side of the rotating shaft 302b. One end of the torsion spring 302d is fixed to the inner wall of the support frame 302c, and the other end is fixed to one side of the locking block 301c.

[0060] When the door body 301a needs to be opened, the locking block 301c is pushed away, and the locking block 301c applies pressure to the torsion spring 302d, and then the locking block 301c is separated from the moving bar 301b, and then the locking block 301c is released. At this time, the rebound force of the torsion spring 302d is used to return the locking block 301c to its original position. After opening the door body 301a, the roller 101 is placed outside the expansion plate 202b. After the placement is completed, the door body 301a is closed. The movement of the door body 301a drives the support shaft 302a to move, and the movement of the support shaft 302a drives the moving bar 301b to move. The moving bar 301b moves to squeeze the chamfer 301c-1 at one end of the locking block 301c, so that the locking block 301c is slightly opened, and then the moving bar 301b is moved to the inner wall of the locking block 301c to engage, thereby completing the closing of the door body 301a.

[0061] Specifically, a support plate 302e is provided at one end of the locking block 301c, and a placement plate 302f is provided at one end of the support frame 302c.

[0062] One end of the placement plate 302f is fixed to one end of the second placement rack 103. The placement plate 302f is used to support the support rack 302c. By moving the support plate 302e, the movement of the support plate 302e will drive the locking block 301c to move. The support plate 302e is used to support the locking block 301c to prevent the locking block 301c from shifting.

[0063] Specifically, the adjusting member 201 also includes an adjusting column 201f which is rotatably connected to the end of the threaded rod 201c through a bearing, a lifting column 201g is fixed to the top of the adjusting column 201f, a lifting plate 201h is fixed to the top of the lifting column 201g, a fixing frame 201i is fixed between the first placement rack 102 and the second placement rack 103, an adjusting bolt 201j is connected to the fixing frame 201i through rotation, a lifting sleeve 201k is fixed to the bottom of the lifting column 201g, a connecting sleeve 201l slides inside the lifting sleeve 201k, a spring 201m is fixed to one side of the connecting sleeve 201l, the other end of the spring 201m is fixed to the inner wall of the lifting sleeve 201k, and the end of the connecting shaft 202c is inserted into the connecting sleeve 201l.

[0064] The lifting sleeve 201k is slidably connected to the door body 301a and can be stably lifted and lowered in the door body 301a. The lifting column 201g above the lifting sleeve 201k is a two-section splicing structure. When the door body 301a is opened, the lifting sleeve 201k can drive the lower section and the upper section of the lifting column 201g to separate, thereby preventing the lifting column 201g from hindering the replacement of the roller 101. The lifting plate 201h and the adjusting bolt 201j are connected by a threaded rotation. By rotating the adjusting bolt 201j, the lifting plate 201h can be driven to rotate. 1h is lifted and lowered, so that the lifting plate 201h can drive the lifting columns 201g at both ends thereof to lift and lower, so that the two lifting columns 201g drive the threaded rod 201c and the connecting shaft 202c to lift and lower through the adjusting column 201f and the connecting sleeve 201l, so that the roller 101 can be lifted and lowered stably, and the spring 201m is in a compressed state. By pulling the connecting sleeve 201l, the connecting shaft 202c and the connecting sleeve 201l can be separated, so that the door body 301a can be opened at this time.

[0065] When in use, if the size or material of the roller 101 needs to be changed, first open the door body 301a, move the support plate 302e, and the support plate 302e moves to drive the engaging block 301c to move. The engaging block 301c moves to apply pressure to the torsion spring 302d, and the engaging block 301c moves to separate from the moving bar 301b. Then open the door body 301a, and the movement of the door body 301a drives the support shaft 302a to move. The movement of the support shaft 302a drives the moving bar 301b to move. 01b moves, and then releases the support plate 302e. At this time, the rebound force of the torsion spring 302d returns the locking block 301c to its original position. After the door body 301a is opened, the roller 101 is placed outside the expansion plate 202b, and then the door body 301a is closed, so that the connecting shaft 202c enters the inner wall of the door body 301a. The movement of the door body 301a drives the moving bar 301b to squeeze the locking block 301c, so that the locking block 301c is slightly opened, and then the moving bar 301b is moved to the locking position. The inner wall of the closing block 301c is engaged, thereby completing the closing of the door body 301a. When the spacing needs to be adjusted, the sliding ring 201a is rotated, and the sliding ring 201a moves on the threaded rod 201c. The movement of the sliding ring 201a drives the moving ring 201b to move, and the movement of the moving ring 201b drives the fixed block 201d to move, and the movement of the fixed block 201d drives the connecting rod 201e to move. When the connecting rod 201e moves, it drives the four connecting plates 202a to move, and the connecting rod 201e moves. The movement of the connecting plate 202a drives the four expansion plates 202b to move. The movement of the connecting plate 202a drives the hinged rod 202d to move. The movement of the hinged rod 202d can increase the supporting force of the expansion plate 202b. When the connecting plate 202a moves, it will also drive the support rod 202g to move. Through the movement of the support rod 202g, supporting force can be provided to one end of the expansion plate 202b. By moving the expansion plate 202b into the engaging groove of the rolling roller 101, the replacement of the rolling roller 101 is completed.

[0066] By rotating the adjusting bolt 201j, the lifting column 201g can be driven to move, and the position of the threaded rod 201c can be adjusted by the movement of the lifting column 201g, thereby adjusting the distance between the roller 101 and the support roller.

[0067] By replacing the roller 101, it is possible to adapt to materials of different materials, and by moving the roller 101, the distance between the roller 101 and the support roller can be adjusted.
