Description

Technical Field

[0001] This utility model relates to the field of corrugated paper production technology, and in particular to a pressing device for corrugated paper production. Background Technology

[0002] Corrugated cardboard, also known as corrugated paperboard, is made of at least one layer of corrugated paper and one layer of linerboard bonded together. It has good elasticity and extensibility and is mainly used to manufacture cartons, carton fillings, and other packaging materials for fragile goods. In the production process of corrugated cardboard, the corrugated paper and linerboard need to be bonded together with adhesive.

[0003] During the gluing process, corrugated cardboard needs to be pressed and bonded using a clamping device. Existing clamping devices typically use gravity rollers to roll and press the corrugated cardboard. However, the side compression effect of gravity rollers is poor, thus reducing the clamping effect. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as poor side-extrusion effect on corrugated cardboard, which reduces the pressing effect on corrugated cardboard, and to propose a pressing device for corrugated paper production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a pressing device for corrugated paper production, including a fixed frame, which is fixedly connected to the upper end of a belt conveyor. A movable frame is slidably connected to the fixed frame, and a threaded rod is rotatably connected to the upper end of the movable frame. The fixed frame has a threaded hole, and the threaded rod mates with the threaded hole. A pressing roller is rotatably connected to the bottom end of the fixed frame. A grooved frame is fixedly connected to the movable frame, and a spacing adjustment mechanism is connected to the grooved frame. Two parallel pressing mechanisms are connected to the spacing adjustment mechanism.

[0007] Preferably, a turntable is fixedly connected to the upper end of the threaded rod.

[0008] Preferably, the turntable is fitted with an anti-slip sleeve.

[0009] Preferably, the spacing adjustment mechanism includes two parallel movable plates, both of which are slidably connected to the groove frame. A bidirectional screw for adjusting the distance between the two movable plates is rotatably connected to the groove frame. One end of the bidirectional screw is fixedly connected to a connecting shaft, and one end of the connecting shaft extends outside the groove frame. The pressing mechanism is connected to each movable plate.

[0010] Preferably, a handle is fixedly connected to one end of the connecting shaft.

[0011] Preferably, the pressing mechanism includes a movable rod that is slidably inserted into the movable plate. A ball is connected to the bottom end of the movable rod, and a fixing block is fixedly connected to the upper end of the movable rod. An L-shaped plate is fixedly connected to the upper end of the movable plate, and a spring is fixedly connected to the L-shaped plate. One end of the spring is fixedly connected to the upper end of the fixing block.

[0012] The pressing device for corrugated paper production proposed in this utility model has the following advantages:

[0013] The movable frame drives the grooved frame to move downwards, and the grooved frame drives two edge pressing mechanisms to move downwards through the spacing adjustment mechanism. Each edge pressing mechanism squeezes the edge of the corrugated cardboard. After the belt conveyor starts, it transports the corrugated cardboard. After the corrugated cardboard moves, it rolls into contact with the extrusion roller and the edge pressing mechanism. The extrusion roller rolls the surface of the corrugated cardboard, and the edge pressing mechanism rolls and squeezes the edge of the corrugated cardboard, thereby improving the pressing effect on the corrugated cardboard.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1: Refer to Figure 1-2 A pressing device for corrugated paper production includes a fixed frame 1, which is fixedly connected to the upper end of a belt conveyor 2. A movable frame 3 is slidably connected to the fixed frame 1. A threaded rod 4 is rotatably connected to the upper end of the movable frame 3. A threaded hole is opened on the fixed frame 1, and the threaded rod 4 cooperates with the threaded hole. A turntable 5 is fixedly connected to the upper end of the threaded rod 4. An anti-slip sleeve is fitted on the turntable 5. A pressing roller 6 is rotatably connected to the bottom end of the fixed frame 1. A grooved frame 7 is fixedly connected to the movable frame 3. A spacing adjustment mechanism 8 is connected to the grooved frame 7. Two parallel pressing mechanisms 9 are connected to the spacing adjustment mechanism 8.

[0021] Work process:

[0022] The corrugated cardboard is placed on the belt conveyor 2. The spacing adjustment mechanism 8 adjusts the position of the two edge pressing mechanisms 9 so that each edge pressing mechanism 9 is located directly above the edge of the corrugated cardboard. The turntable 5 drives the threaded rod 4 to rotate. After the threaded rod 4 rotates, it moves downward under the limit of the threaded hole. The threaded rod 4 drives the movable frame 3 to move downward. The movable frame 3 drives the pressure roller 6 to move downward. After the pressure roller 6 moves downward a certain distance, it contacts the corrugated cardboard and squeezes it.

[0023] At the same time, the movable frame 3 also drives the groove frame 7 to move downward. The groove frame 7 drives the two edge pressing mechanisms 9 to move downward through the spacing adjustment mechanism 8. Each edge pressing mechanism 9 squeezes the edge of the corrugated cardboard. After the belt conveyor 2 starts, it transports the corrugated cardboard. After the corrugated cardboard moves, it rolls into contact with the extrusion roller 6 and the edge pressing mechanism 9. The extrusion roller 6 rolls the surface of the corrugated cardboard, and the edge pressing mechanism 9 rolls and squeezes the edge of the corrugated cardboard, thereby improving the pressing effect on the corrugated cardboard.

[0024] Example 2: Refer to Figure 4 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the spacing adjustment mechanism 8 includes two parallel movable plates 81. Both parallel movable plates 81 are slidably connected to the groove frame 7. A bidirectional screw 82 for adjusting the distance between the two movable plates 81 is rotatably connected to the groove frame 7. One end of the bidirectional screw 82 is fixedly connected to a connecting shaft 83. One end of the connecting shaft 83 extends outside the groove frame 7. A handle 84 is fixedly connected to one end of the connecting shaft 83. Each movable plate 81 is connected to a pressing mechanism 9. When adjusting the position of the pressing mechanism 9, the handle 84 drives the connecting shaft 83 to rotate. The connecting shaft 83 drives the bidirectional screw 82 to rotate. After the bidirectional screw 82 rotates, the movable plate 81 moves along the length direction of the groove frame 7. The movable plate 81 drives the pressing mechanism 9 to move, thereby adjusting the position of the pressing mechanism 9.

[0025] Example 3: Refer to Figure 4As another preferred embodiment of this utility model, the difference from embodiment 2 is that the pressing mechanism 9 includes a movable rod 91, which is slidably inserted into the movable plate 81. A ball 92 is connected to the bottom end of the movable rod 91, and a fixing block 93 is fixedly connected to the upper end of the movable rod 91. An L-shaped plate 94 is fixedly connected to the upper end of the movable plate 81, and a spring 95 is fixedly connected to the L-shaped plate 94. One end of the spring 95 is fixedly connected to the upper end of the fixing block 93. After the ball 92 contacts the side edge of the corrugated paper, it pushes the movable rod 91 upward. The movable rod 91 pushes the fixing block 93. After the fixing block 93 moves upward, it squeezes the spring 95. The spring 95 generates elastic force after being compressed. The elastic force generated by the spring 95 acts on the movable rod 91, thereby making the ball 92 in close contact with the edge of the corrugated paper.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
