Description

Technical Field

[0001] The utility model relates to the technical field of cardboard production, in particular to a cardboard production deviation rectifying device. Background Art

[0002] With the rapid development of people's living standards, cardboard is used more and more frequently in life, and cardboard is widely used in carton processing and packaging, etc.

[0003] A corrugated cardboard production line generally includes equipment such as a raw paper stand, a gluing machine, a double-sided machine, a longitudinal cutting and indentation machine, a cross-cutting machine, and a stacking machine. When the corrugated cardboard enters the subsequent cutting equipment from the paper outlet of the double-sided machine, due to the different degrees of lateral shaking of the corrugated cardboard during the operation of each wheel, belt or cutter, the cardboard will be deflected and the tail will swing. Therefore, a deviation rectifying device is needed to rectify the cardboard. When rectifying the cardboard, the deviation rectifying mechanism contacts the side of the cardboard and squeezes it. After the side of the cardboard is squeezed, it is easy to warp, thus reducing the deviation rectifying effect of the cardboard. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defect that in the prior art, the deviation rectifying mechanism contacts the side of the cardboard and squeezes it, and after the side of the cardboard is squeezed, it is easy to warp, thus reducing the deviation rectifying effect of the cardboard, and to propose a cardboard production deviation rectifying device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] Design a cardboard production deviation rectifying device, including a mounting frame. A motor is fixedly connected to the bottom end of the mounting frame. Both sides of the upper end of the mounting frame are slidably connected with deviation preventing mechanisms. The output end of the motor is fixedly connected with a bidirectional screw rod for adjusting the distance between the two deviation preventing mechanisms. Each deviation preventing mechanism is connected with a roll-up preventing mechanism for preventing the side of the cardboard from warping;

[0007] The roll-up preventing mechanism includes a connecting plate. One end of the connecting plate is fixedly connected to the deviation preventing mechanism. The other end of the connecting plate is rotatably connected with a rotating plate. A spring is fixedly connected to the upper end of the rotating plate. One end of the spring is fixedly connected to the connecting plate. One side of the rotating plate is rotatably connected with a pressing wheel through a connecting shaft.

[0008] Preferably, an anti-corrosion layer is sprayed on the mounting frame.

[0009] Preferably, the anti-deviation mechanism includes a movable plate which is slidably connected to the mounting frame. A threaded hole is formed in the movable plate and is engaged with the bidirectional screw. A fixing plate is fixedly connected to the upper end of the movable plate, and a mounting plate is fixedly connected to the fixing plate. The connecting plate is fixedly connected to the lower surface of the mounting plate. A plurality of limiting rollers are rotatably connected to the lower surface of the mounting plate at equal intervals along the length direction.

[0010] Preferably, there is a gap between the bottom end of the limiting roller and the upper end surface of the mounting frame.

[0011] Preferably, a recovery mechanism for recovering the side plate of the cardboard is connected to each fixing plate. The recovery mechanism includes a fixing frame which is fixedly connected to the fixing plate. An air inlet is formed on one side of the fixing frame, and an air outlet is formed on the other side of the fixing frame. A heating pipe is fixedly connected inside the fixing frame, and a fan is fixedly connected inside the fixing frame.

[0012] Preferably, a dust-proof net is fixedly connected to the air inlet.

[0013] The beneficial effects of a cardboard production deviation correction device proposed by the present utility model are as follows:

[0014] After the cardboard is corrected, it passes through the bottom end of the pressing wheel. The cardboard pushes the pressing wheel upward, and the pressing wheel drives the rotating plate to rotate upward. After the rotating plate rotates upward, it squeezes the spring. After the spring is compressed, it generates an elastic force. The elastic force generated by the spring pushes the rotating plate downward, and the rotating plate drives the pressing wheel to rotate downward. The pressing wheel rotates downward to roll and squeeze the side of the cardboard, so that the warped part of the cardboard side is flattened, thereby improving the deviation correction effect on the cardboard.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Embodiment 1: Refer to Figures 1 - 3 , a cardboard production deviation correction device, including a mounting frame 1, an anti-corrosion layer is sprayed on the mounting frame 1, a motor 2 is fixedly connected to the bottom end of the mounting frame 1, and both sides of the upper end of the mounting frame 1 are slidably connected with an anti-deviation mechanism 4. The output end of the motor 2 is fixedly connected with a bidirectional screw 3 for adjusting the distance between the two anti-deviation mechanisms 4. Each anti-deviation mechanism 4 is connected with an anti-rolling-up mechanism 5 for preventing the side edges of the cardboard from warping;

[0023] The anti-rolling-up mechanism 5 includes a connecting plate 51. One end of the connecting plate 51 is fixedly connected to the anti-deviation mechanism 4, and the other end of the connecting plate 51 is rotatably connected with a rotating plate 52. The upper end of the rotating plate 52 is fixedly connected with a spring 53. One end of the spring 53 is fixedly connected to the connecting plate 51. One side of the rotating plate 52 is rotatably connected with a pressing wheel 54 through a connecting shaft.

[0024] Working process: The cardboard moves onto the mounting frame 1 and is located between the two anti-deviation mechanisms 4. According to the width of the cardboard, after the motor 2 is powered on and starts, it drives the bidirectional screw 3 to rotate a set number of turns. After the bidirectional screw 3 rotates, the two anti-deviation mechanisms 4 move towards each other by a set distance. The two anti-deviation mechanisms 4 move towards each other by a set distance and contact the two sides of the cardboard to limit the cardboard and correct the deviation of the cardboard, avoiding the cardboard from deviating during the movement;

[0025] After the cardboard is corrected for deviation, it passes through the bottom end of the pressing wheel 54. The cardboard pushes the pressing wheel 54 upward. The pressing wheel 54 drives the rotating plate 52 to rotate upward. After the rotating plate 52 rotates upward, it squeezes the spring 53. After the spring 53 is compressed, it generates an elastic force. The elastic force generated by the spring 53 pushes the rotating plate 52 downward. The rotating plate 52 drives the pressing wheel 54 to rotate downward. The pressing wheel 54 rotates downward to roll and squeeze the side edge of the cardboard, so that the warped part of the side edge of the cardboard is flattened, thereby improving the deviation correction effect on the cardboard.

[0026] Embodiment 2: In Embodiment 1, when rectifying the cardboard by the deviation prevention mechanism 4, the friction between the deviation prevention mechanism 4 and the cardboard is relatively large, which is not conducive to the movement of the cardboard. Refer to Figure 3 , as another preferred embodiment of the present invention, the difference from Embodiment 1 is that the deviation prevention mechanism 4 includes a movable plate 41. The movable plate 41 is slidably connected to the mounting frame 1. A threaded hole is provided in the movable plate 41, and the threaded hole is matched with the bidirectional screw 3. A fixing plate 42 is fixedly connected to the upper end of the movable plate 41. A mounting plate 43 is fixedly connected to the fixing plate 42. A connecting plate 51 is fixedly connected to the lower surface of the mounting plate 43. A plurality of limiting rollers 44 are rotatably connected to the lower surface of the mounting plate 43 at equal intervals along the length direction. There is a gap between the bottom end of the limiting roller 44 and the upper end surface of the mounting frame 1. After the bidirectional screw 3 rotates, it drives the movable plate 41 to move. The movable plate 41 drives the fixing plate 42 to move. The fixing plate 42 drives the mounting plate 43 to move. The mounting plate 43 drives the limiting rollers 44 to move. After the limiting rollers 44 contact the side of the cardboard, they perform limiting and rectifying on it. After the cardboard contacts the limiting rollers 44, it drives the limiting rollers 44 to rotate, thereby reducing the friction suffered by the cardboard during the movement process, and thus not affecting the movement of the cardboard.

[0027] Embodiment 3: In Embodiment 1, when flattening the warped part of the cardboard side plate by the pressing wheel 54, the side of the cardboard shrinks after being pressed, causing the side of the cardboard to be sunken. Refer to Figures 4 - 5 , as another preferred embodiment of the present invention, the difference from Embodiment 1 is that a recovery mechanism 6 for recovering the cardboard side plate is connected to each fixing plate 42. The recovery mechanism 6 includes a fixing frame 61. The fixing frame 61 is fixedly connected to the fixing plate 42. An air inlet 62 is provided on one side of the fixing frame 61. A dust-proof net is fixedly connected to the air inlet 62. An air outlet 63 is provided on the other side of the fixing frame 61. A heating pipe 64 is fixedly connected inside the fixing frame 61. A fan 65 is fixedly connected inside the fixing frame 61. The fan 65 and the heating pipe 64 are powered on and started. After the fan 65 starts, it sucks in external gas. The external gas enters the fixing frame 61 through the air inlet 62. The heating pipe 64 heats the gas inside the fixing frame 61. The heated gas is released from the air outlet 63. The heated gas blows the side of the cardboard, causing the side of the cardboard to expand and the sunken part of the side of the cardboard to recover, thereby improving the rectifying effect of the cardboard.

[0028] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
