DETAILED DESCRIPTION
[0029] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are used for explaining the utility model only, and cannot be understood as limiting the utility model.
[0030] The embodiments will be described below according to the overall structure of the utility model.
[0031] Embodiment one
[0032] A type of anti-rebound plate rolling machine, such as Figures 1-6 As shown, the machine includes a body 1, on which a first extrusion roller 2 and a second extrusion roller 3 are rotatably connected. Specifically, two second extrusion rollers 3 are provided on both sides below the first extrusion roller 2. A first fixing plate 4 and a second fixing plate 5, with their tops flush with the tops of the second extrusion rollers 3, are fixedly connected to both sides of the body 1. At least two guide blocks 10 are slidably connected to the top of the second fixing plate 5 in the vertical direction. The guide blocks 10 allow the rotating shaft of the baffle 7 to rise and fall vertically. Specifically, after the guide blocks 10 are raised, the guide blocks 10 and the baffle 7... The pivot between the plates 7 is flush with the top surface of the first extrusion roller 2. The top of the guide block 10 is rotatably connected to a baffle 7, which can block the curled metal plate. A groove 12 is fixedly connected to the middle of the back of the baffle 7, and a slider 13 is slidably connected in the groove 12. A telescopic column 11 is fixedly connected to the second fixed plate 5. The telescopic column 11 includes a fixed part fixedly connected to the second fixed plate 5 and a telescopic part slidably connected in the fixed part. The telescopic part of the telescopic column 11 is vertically upward and fixedly connected to the slider 13.
[0033] Please see Figures 3-6 The bottom end of the guide block 10 is provided with a limiting structure. Specifically, the limiting structure is a protruding part at the bottom end of the guide block 10. This protruding part cannot pass through the area where the guide block 10 and the second fixed plate 5 are slidably connected. Therefore, it can restrict the guide block 10 from sliding upward. When the guide block 10 moves upward to the highest point, the top end of the guide block 10 is flush with the top end of the first extrusion roller 2. The limiting structure at the bottom end of the guide block 10 can effectively prevent the guide block 10 from uncontrollably separating from the second fixed plate 5. After the top end of the guide block 10 is flush with the first extrusion roller 2, it is beneficial for the metal plate between the baffle 7 and the first extrusion roller 2 to pass over the first extrusion roller 2. The sliding direction of the slider 13 in the groove 12 is parallel to the side of the baffle 7, so that when the telescopic column 11 is extended, the baffle 7 can rotate about the axis of rotation at the connection with the slider 13.
[0034] Example 2
[0035] A type of anti-rebound plate rolling machine, such as Figures 1-6As shown, based on the embodiment one, different from the embodiment one, the side of the body 1 away from the baffle 7 is rotationally connected with a rotating plate 6, the rotating shaft of the rotating plate 6 is located at the top end, the bottom surface of the rotating plate 6 is flush with the bottom end of the first extrusion roller 2, the front surface of the rotating plate 6 is connected with the tension spring 9 between the body 1, the tension spring 9 is used to pull the rotating plate 6, in the process that the curled steel plate pushes the rotating plate 6 to rotate and then falls from the rotating plate 6 and the first fixed plate 4, the elastic force generated by the tension spring 9 being stretched can play a good buffering effect on the falling of the metal plate, so as to avoid that the metal plate suddenly falls and causes the worker to be injured, after the metal plate leaves the rotating plate 6, the tension spring 9 pulls the rotating plate 6 to reset, the top end of the baffle 7 and the top end of the rotating plate 6 are all higher than the top end of the first extrusion roller 2, so as to avoid that the metal plate after being curled and pressed falls off from the top end of the baffle 7 or the rotating plate 6.
[0036] Please refer to Figures 2-6 The body 1 is fixedly connected with at least two blocking rods 8 on the side provided with the first fixed plate 4, the blocking rod 8 is arc-shaped, and the top end is flush with the top surface of the second extrusion roller 3, the blocking rod 8 can block the metal plate falling from the rotating plate 6 and the first fixed plate 4, so as to avoid that the metal plate after being curled falls and causes the worker to be injured, the rotating plate 6 does not contact the first extrusion roller 2, the second extrusion roller 3 and the blocking rod 8 when rotating, so as to avoid that the first extrusion roller 2, the second extrusion roller 3 and the blocking rod 8 limit the rotation of the rotating plate 6.
[0037] The working principle of the utility model is as follows: the metal plate is inserted into the first extrusion roller 2 and the second extrusion roller 3 from one side of the rotating plate 6, and is subjected to curling and pressing under the action of friction between the first extrusion roller 2 and the second extrusion roller 3, the metal plate after curling and pressing falls between the first extrusion roller 2 and the baffle 7, at this time, the telescopic column 11 at the back of the baffle 7 is elongated, because the telescopic column 11 is elongated along the vertical direction, the sliding block 13 slides in the sliding groove 12, the guide block 10 is lifted, at the same time, the baffle 7 is rotated around the rotating shaft connected with the guide block 10, after the guide block 10 is lifted, the rotating shaft between the guide block 10 and the baffle 7 is flush with the top surface of the first extrusion roller 2, at this time, the center of gravity of the curled metal plate is located between the rotating shaft of the guide block 10 and the first extrusion roller 2, under the pushing of the subsequent rotation of the baffle 7, the center of gravity of the curled metal plate moves away from the baffle 7, the curled metal plate is pushed by the baffle 7 to pass the top end of the first extrusion roller 2 and falls between the rotating plate 6 and the first fixed plate 4, under the influence of the gravity and inertia of the metal plate, the rotating plate 6 is impacted and rotated, the tension spring 9 is stretched in the process and plays a certain buffering role, so that the metal plate can fall between the blocking rod 8 and the first fixed plate 4 after being buffered, if the metal plate still needs to be curled and pressed again, the metal plate is inserted into the first extrusion roller 2 and the second extrusion roller 3 from one side of the rotating plate 6 again.
[0038] Although the embodiments of the utility model have been shown and described, the specific embodiments are only the explanation of the utility model, and are not the limitation of the utility model, and the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable way, and the person skilled in the art can make the modification, replacement and change of the embodiments without the creative contribution after reading the specification without departing from the principles and the purpose of the utility model, but as long as in the claim range of the utility model, it is protected by the patent law.
