DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-5 As shown, the utility model provides a composite pipe plate rolling machine, comprising a plate rolling machine body 1, the plate rolling machine body 1 is a three-roller symmetrical plate rolling machine, a feed plate 2 is arranged at the feed inlet of the plate rolling machine body 1, the middle part of the feed plate 2 is a disconnected structure, and a plurality of rollers 3 arranged at intervals are rotatably installed at the disconnected part, the axis of the roller 3 is parallel to the axis of the working roller of the plate rolling machine body 1, and the top of the roller 3 and the top of the working roller below the plate rolling machine body 1 are located on the same horizontal plane, so as to facilitate the feeding of the plate, a centering limit mechanism 4 is arranged on the feed plate 2, and a clamping mechanism 5 is arranged on the top of the centering limit mechanism 4;

[0030] The centering limit mechanism 4 includes a bidirectional screw 41 rotatably installed at the bottom of the feed plate 2 and a driving motor 42 whose rotating shaft is fixed to the bidirectional screw 41. The axis of the bidirectional screw 41 is parallel to the axis of the roller 3. Two relatively arranged moving seats 43 are threadedly connected to the bidirectional screw 41. The two moving seats 43 are respectively located on opposite threaded sections of the bidirectional screw 41. A plurality of limit rods 44 are vertically fixed to the top of the moving seat 43. The tops of the plurality of limit rods 44 respectively pass through the intervals between the plurality of rollers 3 and extend above them. A rotating drum 45 is rotatably installed on the side walls of the limit rods 44. The rotating drum 45 is located above the roller 3.

[0031] After the staff puts the plate onto the roller 3, the driving motor 42 drives the bidirectional screw 41 to rotate, so that the two moving seats 43 move toward each other, and the limit rods 44 press against the two sides of the plate. During the movement, the horizontal position of the plate is corrected to prevent it from shifting, and the setting of the rotating drum 45 makes it smoother during feeding.

[0032] The clamping mechanism 5 includes a horizontal plate 51 and a clamping rod 52. One end of the horizontal plate 51 is fixed to the top of the limiting rod 44, and the other end thereof extends toward the middle section of the feed plate 2. A clamping rod 52 is vertically slidably mounted on the horizontal plate 51. The clamping rod 52 is located on the side of the limiting rod 44 close to the middle section of the feed plate 2, and a roller 55 is rotatably mounted on the bottom end thereof. A plurality of slots 53 are spaced apart along the vertical direction on one side of the clamping rod 52, and a clamping plate 54 which is engaged with one of the slots 53 is slidably mounted on the top of the horizontal plate 51.

[0033] After the centering limit mechanism 4 limits the orientation of the plate, the clamping rod 52 can limit the tail end of the plate to prevent the tail end of the plate from being greatly lifted up when the front end of the plate is rolled, causing danger to the staff. At the same time, the setting of multiple slots 53 and clamping plates 54 enables the clamping rod 52 to have an adjustment function. The clamping plate 54 can be inserted into the corresponding slot 53 according to the thickness of different plates to expand the scope of application. The setting of the roller 55 can reduce the friction between the plate and prevent large wear on the plate.

[0034] As a preferred technical solution of the utility model: teeth 56 are provided at the bottom of the clamping plate 54, and grooves 57 engaged with the teeth 56 are provided at the top of the cross plate 51. The arrangement of the teeth 56 and the grooves 57 can enhance the stability of the clamping plate 54 when fixing the clamping rod 52, and prevent it from escaping from the clamping groove 53.

[0035] As a preferred technical solution of the utility model: multiple horizontal plates 51 are connected and fixed by a first connecting plate 6, multiple card plates 54 are connected and fixed by a second connecting plate 7, a handle 8 is provided on the top of the first connecting plate 6, and a handle 9 is provided on the second connecting plate 7. The setting of the first connecting plate 6 and the second connecting plate 7 enables the multiple horizontal plates 51 or multiple card plates 54 to move synchronously to shorten the adjustment time. The setting of the handle 8 and the handle 9 makes it convenient for the staff to move the first connecting plate 6 and the second connecting plate 7.

[0036] As a preferred technical solution of the utility model: the feed plate 2 and the rolling machine body 1 are hingedly connected, and a support rod 10 is connected to one side of the bottom of the feed plate 2. The end of the support rod 10 away from the feed plate 2 is plugged into a slot opened on the rolling machine body 1. The hinged method allows the feed plate 2 to be folded when not in use to reduce the occupied space.
