Description

Technical Field

[0001] This utility model belongs to the field of paper product manufacturing equipment, and specifically relates to a paper product forming and wet pressing production line. Background Technology

[0002] Currently, the manufacturing process of paper products generally includes forming and wet pressing. First, a forming machine collects pulp and presses it into a wet blank. Then, the wet blank is transferred to a wet press using transfer equipment or manually. The wet press further presses the paper to produce the finished product. Since the forming machine completes the forming process by collecting pulp and pressing, while the wet press requires dehumidification and other processes, the wet pressing process takes much longer than the forming process. In assembly line production, the efficiency of the forming machine needs to be reduced to match the working time of the wet press. This reduces the overall production efficiency, as the forming machine's efficiency is not fully utilized, resulting in a waste of effective working time. Utility Model Content

[0003] To overcome the shortcomings and problems of existing technologies, this utility model provides a paper product forming and wet pressing production line, which can effectively improve the working efficiency of the forming machine and greatly enhance the overall working efficiency.

[0006] The molding machine includes a molding frame with a slurry tank at the bottom. The molding frame is equipped with two slurry lifting mechanisms, each of which is connected to a slurry lifting mold. The molding frame is also equipped with two sets of transverse slide rails, each of which is equipped with an upper molding mold that matches the two slurry lifting molds. The upper molding mold is connected to a transverse pushing cylinder, which drives the upper molding mold to slide along the transverse slide rail.

[0007] The slurry lifting mechanism includes a lifting cylinder, which is connected to a cross frame. Vertical sliding columns are connected to both ends of the cross frame.

DETAILED DESCRIPTION

[0017] In order to facilitate the understanding of those skilled in the art, the utility model is further described in detail in combination with the drawings and specific embodiments.

[0018] For example, Figure 1As shown, a paper product forming and wet pressing production line includes a forming machine 1 and a wet press 2. The forming machine 1 is a dual-station forming machine with two stations, capable of simultaneously forming two wet blanks. There are four wet presses 2, arranged in pairs as a group. The two groups of wet presses 2 are located on opposite sides in front of the forming machine 1, and all four wet presses 2 can operate simultaneously. A material transfer robot 3 is installed between the two groups of wet presses 2. A discharge conveyor 4 is located on one side of the material transfer robot 3. The material transfer robot 3 is used for material transfer, transferring the wet blanks produced by the forming machine 1 to the wet press 2, and transferring the finished products completed by the wet press 2 to the discharge conveyor 4. The discharge conveyor 4 is used to convey the finished products out. The material transfer robot 3 is a multi-jointed robot, which is flexible and facilitates material transfer.

[0019] like Figure 2 and Figure 3 As shown, the forming machine 1 includes a forming frame 11, with a pulp tank 12 at the bottom for storing pulp. Two pulp-scooping and lifting mechanisms 13 are mounted on the forming frame 11, each connected to a pulp-scooping mold 14. The lifting mechanisms 13 drive the pulp-scooping mold 14 to rise from the pulp tank 12, thus completing pulp scooping. The forming frame 11 also has two sets of transverse slide rails 15, each with a forming upper mold 16 matching the two pulp-scooping molds 14. The forming upper mold 16 is connected to a transverse pushing cylinder 17, which drives it to slide along the transverse slide rails 15. The pulp-scooping and lifting mechanisms 13 drive the pulp-scooping mold 14 to rise and press against the forming upper mold 16, thus completing the production of the wet blank. The transverse pushing cylinder 17 drives the forming upper mold 16 to move laterally, exposing the wet blank for easy handling and transfer by the material transfer robot 3. The slurry lifting mechanism 13 includes a lifting cylinder 131, which is connected to a crossbeam 132. Vertical sliding columns 133 are connected to both ends of the crossbeam 132. The vertical sliding columns 133 are connected to the slurry mold 14. The forming frame 11 is provided with a sliding hole 134 fitted onto the vertical sliding column 133. The lifting cylinder 131 drives the vertical sliding column 133 to rise and fall through the crossbeam 132, thereby driving the slurry mold 14 to rise and fall. The vertical sliding column 133 slides along the sliding hole 134, which plays a good guiding and positioning role.

[0020] like Figure 4As shown, the wet press 2 comprises a wet press frame 21, which is provided with a fixed lower die 22 and a movable upper die 23 arranged oppositely, the movable upper die 22 is connected with a wet press lifting mechanism 24, and the movable upper die 22 is driven to lift through the wet press lifting mechanism 24. The wet press lifting mechanism 24 comprises a wet press lifting cylinder 241 fixed on the top of the wet press frame 21, the cylinder rod of the wet press lifting cylinder 241 is connected with the movable upper die 23, and the cylinder rod of the wet press lifting cylinder 241 is telescopic to drive the movable upper die 23 to lift. Four guide columns 25 are arranged on the wet press frame 21, the wet press upper die 23 is provided with guide holes 26 matched with the guide columns 25, the guide columns 25 are inserted into the guide holes 26, and the guide holes 26 slide along the guide columns 25 when the wet press upper die 23 lifts, so that the wet press upper die 23 is well guided and positioned. The wet blank is placed on the fixed lower die 22, the wet press lifting mechanism 24 drives the movable upper die 23 to descend and press with the fixed lower die 22, so that the wet blank is wet pressed.

[0021] The working process of the embodiment is as follows: the two stations of the forming machine 1 work simultaneously, when the wet blank is made, the material transfer manipulator 3 transfers the wet blank to a wet press 2 for wet pressing, so that the wet blank is transferred to four wet presses 2, and the four wet presses 2 also work continuously, when the finished product is produced, the material transfer manipulator 3 transfers the finished product from the wet press 2 to the discharging conveying device 4, and the discharging conveying device 4 continuously conveys the finished product out, so that the forming machine 1 and the wet press 2 work continuously.

[0022] The above embodiment is a preferred implementation manner of the utility model, and is not a limitation on the utility model, and any obvious replacement without departing from the utility model concept is within the protection scope of the utility model.
